    Epidermolysis bullosa acquisita is an uncommon autoimmune bullous disease of the skin and mucous membranes. It is chronic, disabling, and difficult to treat. We describe a case of severe epidermolysis bullosa acquisita of 7 years' duration that had been treated with azathioprine, corticosteroids, chlorambucil, plasma exchanges, cyclophosphamide, cyclosporine, and colchicine without any lasting effect. Seven cycles of treatment were administered with immunoglobulin given intravenously at a low dose, 40 mg/kg body weight daily for 5 days. The patient was free of disease for 10 months after the initiation of therapy. We suggest that low-dose regimens of immunoglobulins may be as effective in this disease as the high-dose regimens suggested in the literature, and at much lower cost.

    Full Text Available Abstract Background Multiple system atrophy (MSA is a progressive neurodegenerative disorder of unknown etiology, manifesting as combination of parkinsonism, cerebellar syndrome and dysautonomia. Disease-modifying therapies are unavailable. Activation of microglia and production of toxic cytokines suggest a role of neuroinflammation in MSA pathogenesis. This pilot clinical trial evaluated safety and tolerability of intravenous immunoglobulin (IVIG in MSA. Methods This was a single-arm interventional, single-center, open-label pilot study. Interventions included monthly infusions of the IVIG preparation Privigen®, dose 0.4 gram/kg, for 6 months. Primary outcome measures evaluated safety and secondary outcome measures evaluated preliminary efficacy of IVIG. Unified MSA Rating Scale (UMSARS was measured monthly. Quantitative brain imaging using 3T MRI was performed before and after treatment. Results Nine subjects were enrolled, and seven (2 women and 5 men, age range 55–64 years completed the protocol. There were no serious adverse events. Systolic blood pressure increased during IVIG infusions (p Conclusions Treatment with IVIG appears to be safe, feasible and well tolerated and may improve functionality in MSA. A larger, placebo-controlled study is needed.

    Full Text Available Alzheimer's disease (AD is the most common neurodegenerative disorder. Currently available therapies are symptomatic but do not alter underlying disease progression. Immunotherapeutic approaches such as anti Aβ peptide active vaccination trials have had limited success to date. Intravenous immunoblobulin (IVIg is widely used in immune-mediated neurological disorders such myasthenia gravis and Guillain-Barre syndrome. These preparations have been obtained from the pooled plasma of healthy human donors and contain natural anti-amyloid antibodies and are well tolerated. A small pilot study of passive immunotherapy using IVIg has suggested cognitive improvement. A multicenter phase III trial is ongoing and will determine whether or not this treatment can ameliorate cognitive deficits in mild-to-moderate AD. Here, we briefly review the pathogenic role of amyloid and tau in AD, as well as immunotherapeutic efforts to date. We also summarize what is known about naturally occurring anti-Aβ and tau antibodies in IVIg with a view toward explaining potential mechanisms underlying their therapeutic effects.

    Full Text Available Mohamed Mahdi-Rogers, Yusuf A RajaballyNeuromuscular Clinic, Department of Neurology, University Hospitals of Leicester, Leicester, UKAbstract: Chronic inflammatory demyelinating polyneuropathy (CIDP is an acquired heterogeneous disorder of immune origin affecting the peripheral nerves, causing motor weakness and sensory symptoms and signs. The precise pathophysiology of CIDP remains uncertain although B and T cell mechanisms are believed to be implicated. Intravenous immunoglobulins (IVIg have been shown in a number of trials to be an effective treatment for CIDP. IVIg is thought to exert its immunomodulatory effects by affecting several components of the immune system including B-cells, T-cells, macrophages and complement.

    Gait impairment is a common presenting symptom in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). However, gait parameters have not previously been evaluated in detail as potential independent outcome measures. We prospectively measured changes in spatiotemporal gait parameters of 20 patients with CIDP at baseline and following treatment with intravenous immunoglobulin (IVIG), using GAITRite® a computerized walkway system with embedded sensors. Overall, study patients showed significant improvements in gait velocity, cadence, stride length, double support time, stance phase, and swing phase following IVIG treatment. Mean changes in velocity, stance phase, and swing phase, exhibited the greatest statistical significance among the subgroup that exhibited clinically meaningful improvement in Inflammatory Neuropathy Cause and Treatment disability score, Medical Research Council sum score, and grip strength. Assessment of gait parameters, in particular velocity, step phase and swing phase, is a potentially sensitive outcome measure for evaluating treatment response in CIDP.

    Full Text Available Intravenous immunoglobulin (IVIG is used in the treatment of neuropathy. This case report presents, for the first time, a patient with severe periodontal destruction after chronic therapy with IVIG. The patient reported having extracted his maxillary anterior teeth himself due to high mobility. Clinical examination and radiographic images show a generalized and severe periodontitis. No significant alterations in genetic or microbiological features were observed. The present case suggests that periodontal disease aggravation could be considered a new adverse effect of IVIG therapy. Postulated mechanisms are immune complexes formation, complement activation, and a direct effect in osteoclasts. In conclusion, it is important that patients that will receive IVIG treatment underwent dental evaluation.

    Epilepsy is the most common neurological disease in childhood; depending on the definition of drug-resistant epilepsy, incidence varies from 10% to 23% in the paediatric population. The objective of this study was to account for the decrease in the frequency and/or monthly duration of epileptic seizures in paediatric patients with drug-resistant epilepsy treated with antiepileptic drugs, before and after adding intravenous immunoglobulin G (iIV IgG). This is an analytic, observational, retrospective case-control study. We studied paediatric patients with drug-resistant epilepsy who were treated with IV IgG at the Centro Médico Nacional 20 de Noviembre, in Mexico City, from 2003 to 2013. One hundred and sixty seven patients (19.5%) had drug-resistant epilepsy and 44 (5.1%) started adjuvant treatment with IV IgG. The mean age of patients at the beginning of treatment was 6.12 years±5.14); aetiology was structural acquired in 28 patients (73.6%), genetic in 5 (13.1%), immune in 1 (2.6%), and unknown in 4 (10.5%). At 2 months from starting IV IgG, seizure duration had reduced to 66.66%; the frequency of seizures was reduced by 64% at 4 months after starting treatment (P<.001). According to the results of this study, intravenous immunoglobulin may be an effective therapy for reducing the frequency and duration of seizures in paediatric patients with drug-resistant epilepsy.

    We conducted a study to evaluate the efficacy of intravenous (IV) anti-D against IV immunoglobulin (IVIG) in newly diagnosed immune thrombocytopenia (ITP) in children and to identify the clinical characteristics of the children most likely to benefit from one or the other treatment. Children (6 mo to 14 y) with newly diagnosed ITP and a platelet count D or with 0.8 to 1 g/kg IVIG in a randomized manner. Twenty-five patients, mean age of 6.8 years, were treated either with IV anti-D (n=10) or with IVIG (n=15). Both drugs were equally efficient in raising the platelet count above 20,000/μL at 24 hours posttreatment. Children who presented with bleeding stage 1 or 2 (no mucosal bleeding) responded better to IVIG treatment, in terms of an increase in platelet count at 24 hours posttreatment (P=0.04). Hemoglobin drop was greater in the anti-D group (P=0.002). A single bolus dose of 50 μg/kg of IV anti-D is a safe and effective first-line treatment in newly diagnosed ITP in childhood and mucosal bleeding is a poor prognostic factor for treatment with IVIG.

    The management of refractory recurrent pericarditis is challenging. Previous clinical reports have noted a beneficial effect of high-dose intravenous human immunoglobulins (IvIgs) in isolated and systemic inflammatory disease-related forms. In this article, we analyzed retrospectively our clinical experience with IvIg therapy in a series of clinical cases of pericarditis refractory to conventional treatment. We retrospectively analyzed 9 patients (1994 to 2010) with refractory recurrent pericarditis, who received high-dose IvIg as a part of their medical treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs), steroids, or colchicine treatment was not discontinued during IvIg treatment. No patients had a history of autoimmune or connective tissue diseases. During an average period of 11 months from the first recurrence, patients had experienced a mean of 5 relapses before the first IvIg treatment. In 4 cases, patients showed complete clinical remission with no further relapse after the first IvIg cycle. Two patients experienced a single minor relapse, responsive to short-term nonsteroidal anti-inflammatory drugs. In 2 patients, we performed a second cycle of IvIg after a recurrence of pericarditis, with subsequent complete remission. One patient did not respond to 3 cycles of IvIg and subsequently underwent pericardial window and long-term immunosuppressive treatment. No major adverse effect was observed in consequence of IvIg administration in all the cases. In conclusion, although IvIg mode of action is still poorly understood in this setting, this treatment can be considered as an option in patients with recurrent pericarditis refractory to conventional medical treatment and, in our small series, has proved to be effective in 8 of 9 cases.

    Acute or sub-acute pure dysautonomia is uncommon. We report a case of sub-acute pure pandysautonomia with favorable outcome after intravenous immunoglobulin therapy. A 29-year-old right-handed student, with an uneventful medical history presented, for one month, bilateral loss of visual acuity and digestive disorders, associating diarrhea, vomiting and anorexia. Physical examination revealed bilateral intrinsec oculomotor nerve palsy, a dryness syndrome and severe orthostatic hypotension. Ophthalmologic examination showed bilateral diffuse parasympathic impairment associating an Argyll Robertson pupil and full pupil light reflex abolition. Elevated protein level (0.93g/l) was the only cerebrospinal fluid anomaly. Serum tests were negative for anti-gangliosides antibodies. The patient improved slowly after two series of intravenous immunoglobulin infusions. Clinical course and laboratory findings suggest that acute or sub-acute pure pandysautonomia events are likely to be related to acute polyradiculoneuritis. Therefore intravenous polyvalent immunoglobulin infusions should be attempted, even if their efficacy needs to be confirmed.

    Recurrent pericarditis is a troublesome complication of idiopathic acute pericarditis and occurs more frequently in pediatric patients after cardiac surgery (postpericardiotomy syndrome). Conventional treatment with nonsteroidal antiinflammatory drugs, corticosteroids, and colchicine is not always effective or may cause serious adverse effects. There is no consensus, however, on how to proceed in those patients whose disease is refractory to conventional therapy. In such cases, human intravenous immunoglobulin, immunosuppressive drugs, and biological agents have been used. In this report we describe 2 patients with refractory recurrent pericarditis after cardiac surgery who were successfully treated with 3 and 5 monthly high-dose (2 g/kg) intravenous immunoglobulin until resolution of the effusion. Our experience supports the effectiveness and safety of this therapy. Copyright © 2014 by the American Academy of Pediatrics.

    Toxic epidermal necrolysis (TEN) is a rare, severe adverse drug reaction. Steven-Johnson syndrome (SJS) represents the milder end of the spectrum. The exact pathogenesis of TEN and SJS is still unknown and many drugs, including prednisolone, cyclosporin and intravenous immunoglobulin (IVIG), have been used in an attempt to halt the disease process. The use of IVIG in particular is controversial. We share our experience with the use of IVIG in six patients with TEN. We will also review the various proposed mechanisms underlying TEN, the mechanism of action of IVIG in TEN and summarise useful treatment options.

    Intramuscular Immunoglobulin (IMIG) have been used for 40 years in substitution therapy for antibody deficiencies and as prophylaxis for and treatment of several infectious diseases. Modified and intact intravenous immunoglobulin preparations (IVIG) have now been available for more than 10 years: only the intact product express full Fc- mediated functions with a biological half-life of IgG (3-4 weeks). These preparations have constituted an important achievement in the treatment of humoral immunodeficiencies also resulting in a dramatic improvement of the prognosis. The use of IVIG has also modified the therapeutic approach to several secondary and acquired immunodeficiencies. Treatment with IVIG for immune modulation in several diseases is investigated: substantial data indicate a useful role in selected cases of idiopathic thrombocytopenic purpura, Kawasaky disease and in some neurologic diseases. IVIG are substantially safe and severe side effects have been rarely reported.

    2005-12-01

    Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease with diverse manifestations. We suggest that intravenous immunoglobulin (IVIg) therapy may be beneficial and safe for various manifestations in SLE. A structured literature search of articles published on the efficacy of IVIg in the treatment of SLE between 1983 and 2005 was conducted. We searched the terms "IVIg," "intravenous immunoglobulin," "lupus," "SLE," and "systemic lupus erythematosus." The various clinical manifestations of SLE that were reported to be successfully treated by IVIg in case reports include autoimmune hemolytic anemia, acquired factor VIII inhibitors, acquired von Willebrand disease, pure red cell aplasia, thrombocytopenia, pancytopenia, myelofibrosis, pneumonitis, pleural effusion, pericarditis, myocarditis, cardiogenic shock, nephritis, end-stage renal disease, encephalitis, neuropsychiatric lupus, psychosis, peripheral neuropathy, polyradiculoneuropathy, and vasculitis. The most extensive experience is with lupus nephritis. There are only a few case series of IVIg use in patients with SLE with various manifestations, in which the response rate to IVIg therapy ranged from 33 to 100%. We suggest that IVIg devoid of sucrose, at a dose of 2 g/kg over a 5-d period given uniformly and at a slow infusion rate in patients without an increased risk for thromboembolic events or renal failure, is a safe and beneficial adjunct therapy for cases of SLE that are resistant to or refuse conventional treatment. The duration of therapy is yet to be established. Controlled trials are warranted.

    2012-02-01

    Idiopathic solar urticaria (SU) is a rare, debilitating photodermatosis, which may be difficult to treat. First-line treatment with antihistamines is effective in mild cases, but remission after phototherapeutic induction of tolerance is often short-lived. Other treatment options include plasma exchange, photopheresis and cyclosporin. We present two cases of severe, idiopathic SU, which were resistant to conventional treatment. Both patients achieved remission after administration of intravenous immunoglobulin (IVIg) and have remained in remission at 13 months and 4 years, respectively. There are only two case reports of successful treatment of solar urticaria with IVIg. In our experience IVIg given at a total dose of 2 g\\/kg over several 5-day courses about a month apart is an effective treatment option for severe idiopathic SU. It is also generally safe, even if certainly subject to significant theoretical risks, such as induction of viral infection or anaphylaxis.

    To evaluate factors influencing the efficacy and safety of intravenous immunoglobulins (IVIG) therapy for West syndrome. We investigated seizure outcomes in 70 patients who received IVIG treatment for West Syndrome during the first 3months after the onset of epileptic spasms. IVIG was administered for 3 consecutive days (initial IVIG treatment) at dosages ranging from 100 to 500mg/kg/day. If spasms disappeared within 2weeks of the initial treatment, maintenance IVIG treatment was commenced. We evaluated seizure outcomes at 2weeks (initial evaluation), at 2years (long-term evaluation), and the last visit (last follow-up evaluation) after the initial IVIG treatment. We analyzed dosages of IVIG, age at onset of spasms, treatment lag, and etiologies between responders and non-responders. Among the patients, 7/70 (10.0%) had cessation of spasms and resolution of hypsarrhythmia at the initial evaluation. Another 6/70 patients (8.6%) were found to have cessation of spasms at the long-term evaluations. The treatment lag in responders was shorter than that in non-responders (PWest syndrome. IVIG therapy has a good safety profile and we would recommend it for West syndrome cases with drug resistance, severe complications associated with profound brain damage, severe brain atrophy, and in immunocompromised patients.

    Kawasaki disease (KD) is a systemic vasculitis of unknown etiology and it is therefore worth examining the multifactorial interaction of genes and environmental factors. Targeted genetic association and genome-wide association studies have helped to provide a better understanding of KD from infection to the immune-related response. Findings in the past decade have contributed to a major breakthrough in the genetics of KD, with the identification of several genomic regions linked to the pathogenesis of KD, including ITPKC, CD40, BLK, and FCGR2A. This review focuses on the factors associated with the genetic polymorphisms of KD and the pharmacogenomics of the response to treatment in patients with intravenous immunoglobulin resistance.

    1995-07-01

    In this uncontrolled study 15 patients with ANCA-associated systemic vasculitis, who were poor responders to conventional therapy, were treated with single or multiple courses of intravenous immunoglobulin (IVIG), 30 g/day over 5 days. Clinical and serological evaluation was performed before and 4 weeks after IVIG. Six of the 15 patients experienced clinically significant benefit from IVIG. Improvement was confined to single organ manifestations (skin, ENT findings), no improvement was seen with conjunctivitis and scleritis, pericarditis or nephritis. No patient experienced complete remission after IVIG. Repeated courses of IVIG at 4-week intervals were no more effective than single courses. In six anti-proteinase 3 (PR3)-positive patients pretreatment sera were incubated with F(ab')2 fragments of the IVIG preparation in vitro to measure the inhibitory effect of IVIG on anti-PR3 activity. An inhibition of anti-PR3 activity by 25-70% was observed; this did not correlate with clinical effects. Approximately 40% of patients benefited from IVIG treatment, though complete remission of disease activity did not occur. Neither clinical characteristics nor the inhibitory effect of the IVIG preparation on serum anti-PR3 activity in vitro predicted clinical response to this treatment modality.

    The effects of immunoglobulin G and immunoglobulins enriched with immunoglobulin A and immunoglobulin M on blood-brain barrier integrity and survival rates in septic rats were comparatively investigated. Sepsis was induced by cecal ligation and perforation in Sprague-Dawley rats. The animals were divided into the following groups: Sham, cecal ligation and perforation, cecal ligation and perforation plus immunoglobulin G (250 mg/kg, intravenous), and cecal ligation and perforation plus immunoglobulins enriched with immunoglobulin A and immunoglobulin M (250 mg/kg, intravenous). Immunoglobulins were administered 5 mins before cecal ligation and perforation and the animals were observed for behavioral changes for 24 hrs following cecal ligation and perforation. Blood-brain barrier permeability was functionally and structurally evaluated by determining the extravasation of Evans Blue and horseradish peroxidase tracers, respectively. Immunohistochemistry and Western blotting for occludin were performed. The high mortality rate (34%) noted in the septic rats was decreased to 15% and 3% by immunoglobulin G and immunoglobulins enriched with immunoglobulin A and immunoglobulin M, respectively (p immunoglobulin G and immunoglobulins enriched with immunoglobulin A and immunoglobulin M alleviated the symptoms of sickness behavior in the septic rats, with the animals becoming healthy and active. Increased extravasation of Evans Blue into the brain tissue of the septic rats was markedly decreased with the administration of both immunoglobulin G and immunoglobulins enriched with immunoglobulin A and immunoglobulin M (p immunoglobulin G or immunoglobulins enriched with immunoglobulin A and immunoglobulin M treatment, no ultrastructural evidence of leaky capillaries in the brain was observed in the septic rats, indicating the blockade of the transcellular pathway by immunoglobulins administration.

    Full Text Available La sindrome di Churg-Strauss è una malattia estremamente rara e ancora più raro è riscontrarla in una paziente in stato di gravidanza. Il trattamento iniziale della malattia consiste nella somministrazione di alte dosi di corticosteroidi. I pazienti più gravi o che rispondono poco o insoddisfacientemente ai corticosteroidi vengono solitamente trattati con farmaci citotossici. Le immunoglobuline somministrate per via endovenosa (IgEV stanno dimostrando di essere efficaci nel trattamento di questa patologia, tuttavia non esiste un consenso universale sulla loro effettiva utilità nelle vasculiti sistemiche. Noi presentiamo il caso di una donna con sindrome di Churg-Strauss resistente al trattamento con corticosteroidi e ciclofosfamide. Allorché si riscontrò che la paziente era al 3° mese di gravidanza fu iniziata una terapia con alte dosi di IgEV con ottimi risultati. Questo caso conferma l’utilità del trattamento con IgEV della sindrome di Churg-Strauss e ne dimostra l’efficacia anche in stato di gravidanza.

    Intravenous immunoglobulin (IVIG) has been found to decrease hemolysis in neonatal jaundice due to blood group incompatibility, but a consensus on its usage has not been reached. We conducted a study to compare single versus multiple dose of IVIG in combination with light emitting diode (LED) phototherapy in patients with neonatal jaundice secondary to ABO blood incompatibility, and compared the efficacy of these treatments with that in a group of patients who received LED phototherapy solely. Thirty-nine term neonates with ABO blood group incompatibility were enrolled in the study. Group I received one dose of IVIG (1 g/kg) and LED phototherapy, and group II two doses of IVIG (1 g/kg) and LED phototherapy, whereas group III received LED phototherapy only. In group I, exchange transfusion was performed in one patient (6%) and in group II in one patient (10%). In the control group, none of the patients required exchange transfusion. Duration of LED phototherapy was 4.3 ± 0.7 days in group I + II (IVIG group), 3.9 ± 0.6 days in group III (P = 0.06). Lowest hematocrit level in group I + II was 35.0 ± 7.8 and group III was 38.9 ± 4.2, this was statistically significant (P = 0.034). IVIG therapy, single or multiple, did not affect exchange transfusion, need of erythrocyte transfusion and hospitalization time when used in combination with LED phototherapy in the treatment of ABO hemolytic jaundice in neonates.

    Kawasaki disease (KD) is a systemic vasculitis primarily affecting children who are initial IVIG treatment. This study was conducted to investigate the risk factors for initial IVIG treatment failure in KD. Children who met KD diagnosis criteria and were admitted for IVIG treatment were retrospectively enrolled for analysis. Patients were divided into IVIG-responsive and IVIG-resistant groups. Initial laboratory data before IVIG treatment were collected for analysis. A total of 131 patients were enrolled during the study period. At 48 h after completion of initial IVIG treatment, 20 patients (15.3%) had an elevated body temperature. Univariate analysis showed that patients who had initial findings of high neutrophil count, abnormal liver function, low serum albumin level (≤2.9 g/dL) and pericardial effusion were at risk for IVIG treatment failure. Multivariate analysis with a logistic regression procedure showed that serum albumin level was considered the independent predicting factor of IVIG resistance in patients with KD (p = 0.006, OR = 40, 95% CI: 52.8-562). There was no significant correlation between age, gender, fever duration before IVIG treatment, haemoglobin level, total leucocyte and platelet counts, C-reactive protein level, or sterile pyuria and initial IVIG treatment failure. The specificity and sensitivity for prediction of IVIG treatment failure in this study were 96% and 34%, respectively. Pre-IVIG treatment serum albumin levels are a useful predictor of IVIG resistance in patients with KD. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.

    The clinical significance of platelet associated IgG in ITP detected by direct platelet suspension immunofluorescence test (PSIFT) was studied. The platelet mean life span (MLS) was measured with /sup 111/In-labelled platelets in 17 adult patients. All the patients had shortened platelet MLS. The direct PSIFT was positive in 14 patients. Patients were initially treated with prednisone; 12 patients with poor response to the drug were splenectomised. 8 of these 12 patients were treated with intravenous immunoglobulin (IvIg) before splenectomy. The response to IvIg was as good or better in the 3 patients with negative PSIFT, than in the 5 patients with positive PSIFT.

    The appropriate treatment of pandemic H1N1 influenza which was first identified in April 2009 in Mexico is insufficient especially for immunocompromised patients. We aimed to evaluate the features and prognostic factors of the children with H1N1, especially immunocompromised ones, and whether intravenous immunoglobulin G (IVIG) replacement could aid for a better outcome. Twenty-one hospitalized children with laboratory-confirmed H1N1 were evaluated retrospectively. Data were extracted from files and electronic medical records. The median age was 37 (1-216) months; 62% of them were under 5 years of age and 71.4% had one or more underlying disorders. Main symptoms were high fever, cough, fatigue and vomiting. Lower respiratory tract manifestations were seen in 66.6% of children. Mortality rate was 4.7%. The patient who died had the lowest lymphocyte (100/mm(3) ), thrombocyte (21 000/mm(3) ) and highest blood urea nitrogen (87 mg/dL) levels. Fifty-eight percent of evaluated patients had one of the primary immunodeficiency disorders. Surprisingly, none of the six patients with primary immunodeficiency who are on regular IVIG replacement needed intensive care unit and died. Although median durations of cough, fever and hospitalization were lower, they did not change statistically according to get IVIG replacement regularly (P = 0.47, 0.97, 0.09, respectively). Our study is important while it is the first one that shows the course of primary immunodeficient children with H1N1 infection who were on regular IVIG replacement. A trial of high-dose IVIG may be a useful adjunctive therapy in severe H1N1 influenza, particularly in the immunocompromised patients. © 2014 John Wiley & Sons Ltd.

    Conclusion: The results of this study suggest that although IVIG treatment within 10 days is important to minimize development of cardiac pathology, neither occurrence of CA lesions in IVIG-treated children nor the time frame for resolution of established CA abnormalities was associated with the timing of IVIG administration. Age 40 mm/hour predict a delay in resolution of CA lesions among children with KD.

    Full Text Available Background/Aim. Intravenous immunoglobulin is a blood product made of human polyclonal immunoglobulin G. The mode of action of intravenous immunoglobulin is very complex. It is indicated in treatment of neonatal immune thrombocytopenia and haemolytic disease of the newborn. The aim of the study was to present our experience in the use of intravenous immunoglobulin in a group of term neonates. Methods. We analysed all relevant clinical and laboratory data of 23 neonates who recieved intravenous immunoglobulin during their hospitalization in Neonatal Intensive Care Unit of Mother and Child Health Care Institute over a five year period, from 2006. to 2010. Results. There were 11 patients with haemolytic disease of the newborn and 12 neonates with immune thrombocytopenia. All of them recieved 1-2 g/kg intravenous immunoglobulin in the course of their treatment. There was no adverse effects of intravenous immunoglobulin use. The use of intravenous immunoglobulin led to an increase in platelet number in thrombocytopenic patients, whereas in those with haemolytic disease serum bilirubin level decreased significantly, so that some patients whose bilirubin level was very close to the exchange transfusion criterion, avoided this procedure. Conclusion. The use of intravenous immunoglobulin was shown to be an effective treatment in reducing the need for exchange transfusion, duration of phototherapy and the length of hospital stay in neonates with haemolytic disease. When used in treatment of neonatal immune thrombocytopenia, it leads to an increase in the platelet number, thus decreasing the risk of serious complications of thrombocytopenia.

    Intravenous immunoglobulin therapy is standard for Kawasaki disease (KD) treatment; however, anaphylactic reactions to immunoglobulins are a risk in KD patients with selective IgA deficiency (sIgAD). The therapy for KD associated with sIgAD has not been established. The IgA immune response is believed to play an important role in KD vasculitis. We report the case of a 5-year-old boy with KD and sIgAD treated with intravenous cyclosporine A (CsA, 3.0 mg/kg/day) instead of intravenous immunoglobulin (IVIG). The fever and inflammation immediately resolved without a coronary artery lesion. In KD patients with sIgAD, we believe that an IgA immune response is lacking, which is the reason for milder KD symptoms than in those without sIgAD. This case report aids in clarifying the role of IgA antibodies in KD and provides evidence that CsA is a potential candidate for first-line therapy for patients with KD with contraindications to IVIG.

  1. Treatment response in Kawasaki disease is associated with sialylation levels of endogenous but not therapeutic intravenous immunoglobulin G.

    Full Text Available Although intravenous immunoglobulin (IVIG is highly effective in Kawasaki disease (KD, mechanisms are not understood and 10-20% of patients are treatment-resistant, manifesting a higher rate of coronary artery aneurysms. Murine models suggest that α2-6-linked sialic acid (α2-6Sia content of IVIG is critical for suppressing inflammation. However, pro-inflammatory states also up-regulate endogenous levels of β-galactoside:α2-6 sialyltransferase-I (ST6Gal-I, the enzyme that catalyzes addition of α2-6Sias to N-glycans. We asked whether IVIG failures correlated with levels of α2-6Sia on infused IVIG or on the patient's own endogenous IgG.We quantified levels of α2-6Sia in infused IVIG and endogenous IgG from 10 IVIG-responsive and 10 resistant KD subjects using multiple approaches. Transcript levels of ST6GAL1, in patient whole blood and B cell lines were evaluated by RT-PCR. Plasma soluble (sST6Gal-I levels were measured by ELISA.There was no consistent difference in median sialylation levels of infused IVIG between groups. However, α2-6Sia levels in endogenous IgG, ST6GAL1 transcript levels, and ST6Gal-I protein in serum from IVIG-resistant KD subjects were lower than in responsive subjects at both pre-treatment and one-year time points (p <0.001, respectively.Our data indicate sialylation levels of therapeutic IVIG are unrelated to treatment response in KD. Rather, lower sialylation of endogenous IgG and lower blood levels of ST6GALI mRNA and ST6Gal-I enzyme predict therapy resistance. These differences were stable over time, suggesting a genetic basis. Because IVIG-resistance increases risk of coronary artery aneurysms, our findings have important implications for the identification and treatment of such individuals.

    Intravenous immunoglobulin (IVIG) is an established treatment of immune mediated demyelinating neuropathy including Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy. Recent trials suggest its efficacy in treating relapsing- remitting multiple sclerosis. IVIG exerts a number of effects, which may be beneficial in treating multiple sclerosis (MS): Reduction of inflammation, inhibition of macrophages, and promotion of remyelination. The aim of this study was to provide an overall assessment of the existing trials of safety and effectiveness of IVIG in relapsing- remitting MS compared to other drugs currently available for the treatment of disease activity in MS. A systematic search strategy was applied to MEDLINE (PubMed and Ovid Medline (1990- Nov 2014)), Cochrane Library 2014, and Trip Database 2014, CRD. The reference lists from the identified trials, MS clinical handbooks and guidelines for the use of IVIG were studied. This article was conducted without language restrictions. Randomized controlled trials of IVIG in MS were selected. Sixteen double-blinded trails were randomly selected. Ten trials were excluded and we performed a meta-analysis on the six trials (537 participants) of IVIG in comparison to placebo. The methodological quality of the trials was assessed using Jadad checklist. The meta-analysis showed a significant beneficial effect on proportion of relapse-free patients (OR: 1.693; 95% CI-1.205-2.380), on the proportion of patients who improved (OR:2.977; 95% CI 1.769-5.010; p=0.0001) and deteriorated (OR:0.522; 95% CI0.330-0.827; p=0.006) between placebo and IVIG-treated patients. In addition, there was a reduction in the annual relapse rate in the IVIG group compared to placebo, which was statistically significant (SMD=-0.218; 95% CI-0.412 to -0.024; p=0.028). The results of the meta-analysis did not show significant differences between Expanded Disability Status Scale (EDSS) changes from baseline (SMD,-0.025; 95% CI,-0

    Intravenous immunoglobulin (IVIG) for the treatment of primary immunodeficiency disorders have been administrated for more than 25 years. However, the recognition of the anti-inflammatory and immune-modulatory actions of IVIG resulted broader applications to autoimmunity and systemic inflammatory conditions. The major focus of this review is the usefulness of IVIG therapy in children kidney disease, particularly in severe, atypical hemolytic-uremic syndrome and thrombotic thrombocytopenic purpura, refractory to standard therapy, including plasmaferesis. The role of intravenous immunoglobulins in the treatment and prevention of infection, the most common complication in nephrotic syndrome is also discussed. Probably, in the future, similarly to adults, IVIG will be used for the therapy of some forms of glomerulopathies.

    Kawasaki disease (KD) has become the most common cause of acquired heart disease in children and is also a risk factor for ischemic heart disease in adults. However, Kawasaki disease lacks specific laboratory diagnostic indices. Thus, this study analyzed the T cell activation profiles of Kawasaki disease and assessed their value in the diagnosis of Kawasaki disease and the prediction of intravenous immunoglobulin (IVIG) sensitivity. We analyzed human leukocyte antigen-DR (HLA-DR), CD69 and CD25 expression on peripheral blood CD4+ and CD8+ T cells during the acute phase of KD. We compared the percentages of HLA-DR+/CD69+/CD25+ T cells in the CD4+ and CD8+ T cell populations of IVIG-effective and IVIG-resistant groups. Receiver operating characteristic curves were used to assess the diagnostic value of the above parameters. The median percentage of CD8+HLA-DR+ T cells and the median ratio of CD8+HLA-DR+ T cells/CD8+CD25+ T cells were significantly elevated in the patient group compared with those in the control group during the acute phase of KD. Regarding the diagnosis of Kawasaki disease, the area under the ROC curve was 0.939 for the percentage of CD8+HLA-DR+ T cells. There was a significant difference in the ratio of CD8+HLA-DR+ T cells/CD8+CD69+ T cells between IVIG-resistant patients and IVIG-sensitive patients. Regarding IVIG sensitivity, the area under the ROC curve was 0.795 for it. Excessive CD8+ T cell activation, as well as an imbalance between CD8+ T cell activation and inhibition, underlies the pathogenesis of Kawasaki disease. The percentage of CD8+ HLA-DR+ T cells may be used as an index to diagnose Kawasaki disease. IVIG inhibits CD8+ T cell activation, but excessive CD8+ T cell activation may cause IVIG resistance. The ratio of CD8+HLA-DR+ T cells/CD8+CD69+ T cells may be used as a predictor of IVIG sensitivity. Copyright © 2016. Published by Elsevier Inc.

    While there are guidelines for the use of intravenous immunoglobulins in children with Guillain-Barre syndrome and myasthenia gravis based on high-level evidence studies, data are scarce for the majority of neurologic disorders in this age group. Neuronal antibodies are detected in children with seizures of autoimmune etiology. Intravenous immunoglobulins with their broad immunomodulatory mechanism of action could be ideally effective in different forms of immunedysregulated intractable epilepsies such as autoimmune epilepsy and autoimmune Rasmussen encephalitis. We conducted a systematic review of the literature for evidence of the use of intravenous immunoglobulins in a variety of neurologic diseases in childhood. A comprehensive literature search was conducted using Pubmed as the medical database source without date range. Prospective studies in pediatric groups including objective measures of clinical outcomes were systematically selected. A total of 11 prospective studies were identified in the literature demonstrating a favorable effect of this therapeutic option in children with drug-resistant epilepsy and in cases of encephalitis. No serious adverse effects were reported. No prospective studies about the use of intravenous immunoglobulins in children with demyelinating disorders or neurologic paraneoplasmatic syndromes were found. In this review, we summarize the recent advances in the field of intravenous immunoglobulins used in pediatric neurological diseases. Literature data supports a beneficial effect in this age group. Whilst awaiting the results of large scale studies, administration of intravenous immunoglobulins could be justified in refractory child epilepsy. Otherwise, its use should be guided by the individual needs of each child, depending on the underlying neurological disease.

    Anti-E alloimmunisation is a less common cause of haemolytic disease in the newborn (HDN) and is usually associated with mild to moderate clinical manifestations, that are often less severe than anti-D immunisation. Conventional treatments for HDN are phototherapy and exchange transfusion, the latter still representing a high-risk procedure. Currently, intravenous immunoglobulin has been used as alternative treatment for HDN to reduce the need for exchange transfusion, as well as the length of phototherapy and hospitalisation. We report a case of anti-E HDN treated successfully with intravenous immunoglobulin, as adjuvant treatment to phototherapy.

    Full Text Available Although the measles vaccine has been part of routine national childhood vaccination programs throughout Europe, measles remains a public health concern. High numbers of cases and outbreaks have occurred throughout the European continent since 2011, and an increasing number of cases have been reported in Turkey since 2012. During a recent measles outbreak in Turkey, 2 pregnant women contracted measles prior to delivering preterm infants at Hacettepe University Hospital. Measles virus genomic RNA and IgM antibodies against measles were detected in the cord blood of infants and mothers in both cases. The infants were treated with intravenous immunoglobulin (IVIG and vitamin A. Transient thrombocytopenia was present in 1 infant and treated with an additional dose of IVIG and vitamin A. The infants were discharged, without complications, within 10 days of birth. The successful treatment of these cases suggests that infants who have been exposed to, or infected with, measles may benefit from cotreatment of vitamin A and IVIG.

    Full Text Available Background Glucose-6-phosphate dehydrogenase deficiency alone or concomitant with ABO isoimmunisation is a widespread indication for neonatal exchange transfusion. Aims To evaluate the effectiveness of Intravenous Immunoglobulin in the treatment of neonatal hyperbilirubinemia due to glucose-6-phosphate dehydrogenase deficiency. Methods A retrospective cohort study was conducted between 2006 and 2014 at the Jordan University of Science and technology. The medical records of 43 infants admitted to the neonatal intensive care unit for isolated glucose-6- phosphate dehydrogenase deficiency hemolytic disease of the newborns were reviewed. Patients were divided into two groups. Group I, a historical cohort, included newborns born between 2006 and 2010, Treatment included phototherapy and exchange transfusion. Group II included newborns born between 2011 and 2014, where, in addition to phototherapy, intravenous immunoglobulin was administered. The duration of phototherapy and number of exchange transfusions were evaluated. Results Of 412 newborns that were admitted with neonatal hyperbilirubinemia, Glucose-6-phosphate dehydrogenase deficiency was present in 43. Of these, 22, did not receive intravenous immunoglobulin and served as a control group. The other 21 newborns received intravenous immunoglobulin. There was no difference in the demographic characteristics between the two groups. Infants in the control group were significantly more likely to receive exchange blood transfusion than infants in the immunoglobulin treatment group, but were significantly less likely to need phototherapy. Conclusion Intravenous immunoglobulin is an effective alternative to exchange transfusion in infants with glucose-6-phosphate dehydrogenase deficiency hemolytic disease of the newborn. It is suggested that intravenous immunoglobulin may be beneficial as a prophylaxis for infants with hyperbilirubinemia.

    To evaluate whether the use of intravenous immunoglobulin in newborn infants with isoimmune hemolytic jaundice due to Rh and ABO incompatibility is an effective treatment in reducing the need for exchange transfusion. This study included all direct Coombs' test positive Rh and ABO isoimmunized babies, who admitted in the Neonatal Intensive Care Unit of Ghaem Hospital of Mashhad University of Medical Sciences, Iran, from October 2003 to October 2004. Significant hyperbilirubinemia was defined as rising by >or=0.5 mg/dl per hour. Babies were randomly assigned to received phototherapy with intravenous immunoglobulin (IVIg) 0.5 g/kg over 4 hours, every 12 hours for 3 doses (study group) or phototherapy alone (control group). Exchange transfusion was performed in any group if serum bilirubin exceeded >or=20mg/dl or rose by >or=1mg/dl/h. A total of 34 babies were eligible for this study (17 babies in each group). The number of exchange transfusion, duration of phototherapy and hospitalization days, were significant shorter in the study group versus control group. When we analyzed the outcome results in ABO and Rh hemolytic disease separately, the efficacy of IVIg was significantly better in Rh versus ABO isoimmunization. Late anemia was more common in the IVIg group 11.8% versus 0%, p=0.48. Adverse effects were not observed during IVIg administration. Administration of IVIg to newborns with significant hyperbilirubinemia due to Rh hemolytic disease reduced the need for exchange transfusion but in ABO hemolytic disease there was no significant difference between IVIg and double surface blue light phototherapy.

    Full Text Available Abstract Background Expression of inflammatory cytokines in cerebrospinal fluid (CSF has led to the hypothesis of intrathecal chronic inflammation to explain the denervation observed in post-polio syndrome (PPS. It has been shown that therapy with intravenous immunoglobulin (IVIG improves physical performance and dampens down the inflammatory process at 6 months in PPS patients. We here examined the effects of IVIG on cytokine expression and clinical outcome one year after IVIG treatment. Methods From a previous study with 135 PPS patients included, 41 patients were further evaluated before un-blinding for one year (21 placebo and 20 treated with IVIG, Xepol® 50 mg/ml, and were assessed for clinical variables by performing the Short Form-36 survey (SF-36 questionnaire assessment, the 6 minute walk distance test (6MWT and registering pain level by Visual Analogue Scale (VAS after IVIG treatment. A separate cohort of 37 PPS patients went through lumbar puncture (LP at baseline and 20 patients, treated with IVIG, repeated the LP one year later. Thirty patients affected with other neurological diseases (OND were used as control group. Inflammatory cytokines TNF, TGFβ, IFNγ, IL-23, IL-13 and IL-10 were measured in blood cells and CSF cells with RT-PCR. Results Scores of the physical components of SF-36 were significantly higher at the one year follow up time-point in the IVIG-treated patients when compared to baseline as well as to the control subjects. Pain VAS score and 6MWT improved significantly in the IVIG-treated patients when compared with baseline Relative expression of TNF and IFN-γ in both PBMCs and CSF from PPS patients were increased compared to OND subjects at baseline (p  Conclusions IVIG has effects on relevant QoL variables and inflammatory cytokines up to one year in patients with PPS. This gives a basis for scheduling IVIG in upcoming trials with this therapy.

  16. Is intravenous immunoglobulin effective in toxic epidermal necrolysis and Stevens-Johnson syndrome?

    Full Text Available Toxic epidermal necrolysis and Stevens-Johnson syndrome are severe cutaneous adverse drug reactions. Intravenous immunoglobulin is described as a therapeutic option, however its use is still controversial. Using Epistemonikos database, which is maintained by screening over 20 databases, we identified six systematic reviews, including 39 primary studies. We combined the evidence using tables for summary of findings, following the GRADE approach, and concluded there is uncertainty about the effects of intravenous immunoglobulin because the certainty of the evidence is very low; it probably leads to important adverse effects; and has high cost. Intravenous immunoglobulin should not be used outside the context of a clinical trial, or only in cases where other treatments have failed and there are no resource constraints.

    Pain is a common symptom that affects quality of life in patients with post-polio syndrome. An increase in cytokine in the cerebrospinal fluid suggests that inflammation is pathophysiologically important in post-polio syndrome. Intravenous immunoglobulin might therefore be a therapeutic option. The aim of this study was to analyse the effect of intravenous immunoglobulin treatment on pain in post-polio syndrome. An uncontrolled clinical study. Patients with post-polio syndrome and pain (n = 45) underwent a neurological examination and were interviewed about pain before and 6 months after treatment with intravenous immunoglobulin. Pain intensity was measured on a visual analogue scale. The pain was classified according to the International Association for the Study of Pain criteria as neuropathic when it occurred in an area with decreased sensibility, or nociceptive when signs of inflammation and/or painful joints movements were present. After treatment 31/45 (69%) patients were improved, with a mean visual analogue scale decrease from 53 to 42 (p = 0.001). Eighteen patients (40%) had a decrease of 20 or more points on the visual analogue scale. The effect of treatment did not differ regarding age, gender and severity of disability. Two-thirds of 45 patients with post-polio syndrome and pain reported a decrease on the visual analogue scale for pain after treatment with intravenous immunoglobulin, and 40% reported a decrease of 20 or more points on the visual analogue scale.

    Transverse myelitis (TM) is an immune-mediated disorder of the spinal cord that affects adults and children and that causes motor, sensory and autonomic dysfunction. There is a prolonged recovery phase, which may continue for many years. Neuromyelitis optica (NMO) is an uncommon relapsing inflammatory central nervous system condition in which TM can be the first presenting symptom. As TM and NMO affect many patients in the prime of their working life, the disorder can impose a significant demand on health resources. There are currently no robust controlled trials in children or adults to inform the optimal treatment of TM. However, treatment with intravenous immunoglobulin (IVIG) is being effectively used in the management of a range of neurological conditions. Although other interventions such as plasma exchange (PLEX) in addition to intravenous (IV) methylprednisolone therapy can be beneficial in TM, PLEX is costly and technically challenging to deliver in the acute setting. IVIG is more readily accessible and less costly. To evaluate whether additional and early treatment with IVIG is of extra benefit in TM compared with standard therapy with IV steroids. A multicentre, single-blind, parallel-group randomised controlled trial of IVIG compared with standard therapy for the treatment of TM in adults and children. Patients aged ≥ 1 year diagnosed with either acute first-onset TM or first presentation of NMO. Target recruitment was 170 participants (85 participants per arm). Participants were randomised 1 : 1 to treatment with IV methylprednisolone only or treatment with IV methylprednisolone plus 2 g/kg of IVIG in divided doses within 5 days of the first commencement of steroid therapy. Primary outcome measure - American Spinal Injury Association (ASIA) Impairment Scale at 6 months post randomisation, with a good outcome defined by a two-grade change. Secondary and tertiary outcome measures - ASIA motor and sensory scales, Expanded Disability Status Scale

    Full Text Available Abstract Background The latency of HIV-1 in resting CD4+ T-lymphocytes constitutes a major obstacle for the eradication of virus in patients on antiretroviral therapy (ART. As yet, no approach to reduce this viral reservoir has proven effective. Methods Nine subjects on effective ART were included in the study and treated with high dosage intravenous immunoglobulin (IVIG for five consecutive days. Seven of those had detectable levels of replication-competent virus in the latent reservoir and were thus possible to evaluate. Highly purified resting memory CD4+ T-cells were activated and cells containing replication-competent HIV-1 were quantified. HIV-1 from plasma and activated memory CD4+ T-cells were compared with single genome sequencing (SGS of the gag region. T-lymphocyte activation markers and serum interleukins were measured. Results The latent HIV-1 pool decreased with in median 68% after IVIG was added to effective ART. The reservoir decreased in five, whereas no decrease was found in two subjects with detectable virus. Plasma HIV-1 RNA ≥ 2 copies/mL was detected in five of seven subjects at baseline, but in only one at follow-up after 8–12 weeks. The decrease of the latent HIV-1 pool and the residual plasma viremia was preceded by a transitory low-level increase in plasma HIV-1 RNA and serum interleukin 7 (IL-7 levels, and followed by an expansion of T regulatory cells. The magnitude of the viral increase in plasma correlated to the size of the latent HIV-1 pool and SGS of the gag region showed that viral clones from plasma clustered together with virus from activated memory T-cells, pointing to the latent reservoir as the source of HIV-1 RNA in plasma. Conclusion The findings from this uncontrolled proof-of-concept study suggest that the reservoir became accessible by IVIG treatment through activation of HIV-1 gene expression in latently-infected resting CD4+ T-cells. We propose that IVIG should be further evaluated as an adjuvant

In this study, we aimed to identify useful predictors of therapeutic failure in children with KD. &lt;b&gt;Methods:&lt;/b&gt; We examined 309 children diagnosed with KD at the Kyungpook National University Hospital and the Inje University Busan Paik Hospital between January 2005 and June 2011. We retrospectively reviewed their medical records and analyzed multiple parameters in responders and nonresponders to IVIG. &lt;b&gt;Results:&lt;/b&gt; Among the 309 children, 30 (9.7% did not respond to IVIG. They had significantly higher proportion of neutrophils, and higher levels of aspartate aminotransferase, alanine aminotransferase (ALT, total bilirubin, and N-terminal fragment of B-type natriuretic peptide than did responders. IVIGnonresponders had a significantly longer duration of hospitalization, and more frequently experienced coronary artery lesion, and sterile pyuria. No differences in the duration of fever at initial treatment or, clinical features were noted. &lt;b&gt;Conclusion:&lt;/b&gt; Two independent predictors (ALT?#248;4 IU/L, total bilirubin?#240;.9 mg/dL for nonresponse were confirmed through multivariate logistic regression analysis. Thus elevated ALT and total bilirubin levels might be useful in predicting nonresponse to IVIG therapy in children with KD.

    The dramatic increase in both the number of novel infectious agents and resistance to antimicrobial drugs has incited the need for adjunct therapies in the war against infectious diseases. Exciting recent studies have demonstrated the use of antibodies in the form of intravenous immunoglobulin (IVIg) against infections. By virtue of the diverse repertoire of immunoglobulins that possess a wide spectrum of antibacterial and antiviral specificities, IVIg provides antimicrobial efficacy independently of pathogen resistance and represents a promising alternative strategy for the treatment of diseases for which a specific therapy is not yet available.

    Full Text Available The lack of BTK in X-linked agammaglobulinemia (XLA patients does not affect monocytes and polymorphonuclear cells (PMN phenotype and functions. In this study, we show that XLA patients had an increased frequency of the intermediate monocytes subset and that BTK-deficient monocytes and PMN had a normal expression of receptors involved in the activation and cellular responses. We demonstrate that BTK is not required for migration, phagocytosis and the production of reactive oxygen species (ROS following engagement of FC gamma receptors (FcγR. XLA monocytes and PMN showed an efficient calcium (Ca2+-independent activation of oxidative burst, suggesting that oxidative burst is less dependent by Ca2+ mobilization. The phagocytosis was functional and it remained unaltered also after Ca2+ chelation, confirming the independence of phagocytosis on Ca2+ mobilization. Intravenous immunoglobulin (IVIg infusion exerted an anti-inflammatory effect by reducing the frequency of pro-inflammatory monocytes. In monocytes, the IVIg reduce the oxidative burst and phagocytosis even if these functions remained efficient.

    Full Text Available The problem of intrauterine infection (IUI is still relevant today. Ineffective treatment of this pathology is associated with physiological decline of the immunity in these patients. We have proposed the additional use of intravenous immunoglobulin for the treatment of pregnant women with IUI. There were examined 75 patients with IUI, which was diagnosed in the II trimester. The I group consisted of 40 individuals who received conventional treatment, the II group was formed from 35 women who additionally received intravenous immunoglobulin. On the background of IUI, pregnancy was characterized by an increased incidence of threatened miscarriage and premature labor, gestosis and placental dysfunction; during delivery, premature rupture of amniotic membrane and fetal distress were more common. These patients had placenta with both ultrasonic and histological signs of infection. Among newborns, there was a significant increase in the incidence of pathology associated with intrauterine infection. Additional use of intravenous immunoglobulin in the treatment of IUI during the II trimester of pregnancy in comparison with conventional therapy leads to a significant reduction in the incidence of both obstetric complications and perinatal pathology.

    Kawasaki disease, which is characterised by systemic vasculitides accompanied by acute fever, is regularly treated by intravenous immunoglobulin to avoid lesion formation in the coronary artery; however, the mechanism of intravenous immunoglobulin therapy is unclear. Hence, we aimed to analyse the global expression profile of serum exosomal proteins before and after administering intravenous immunoglobulin. Two-dimensional electrophoresis coupled with mass spectrometry analysis was used to identify the differentially expressed proteome of serum exosomes in patients with Kawasaki disease before and after intravenous immunoglobulin therapy. Our analysis revealed 69 differential protein spots in the Kawasaki disease group with changes larger than 1.5-fold and 59 differential ones in patients after intravenous immunoglobulin therapy compared with the control group. Gene ontology analysis revealed that the acute-phase response disappeared, the functions of the complement system and innate immune response were enhanced, and the antibacterial humoral response pathway of corticosteroids and cardioprotection emerged after administration of intravenous immunoglobulin. Further, we showed that complement C3 and apolipoprotein A-IV levels increased before and decreased after intravenous immunoglobulin therapy and that the insulin-like growth factor-binding protein complex acid labile subunit displayed reverse alteration before and after intravenous immunoglobulin therapy. These observations might be potential indicators of intravenous immunoglobulin function. Our results show the differential proteomic profile of serum exosomes of patients with Kawasaki disease before and after intravenous immunoglobulin therapy, such as complement C3, apolipoprotein A-IV, and insulin-like growth factor-binding protein complex acid labile subunit. These results may be useful in the identification of markers for monitoring intravenous immunoglobulin therapy in patients with Kawasaki disease.

    This is a retrospective analysis of 25 children with severe Guillain-Barre syndrome admitted to our PICU. All children were treated with intravenous immunoglobulins (IVIG) in a dose of 2 g/kg body weight over 2-5 days in addition to supportive and respiratory care. Seventeen children were elective admissions to the PICU whereas 8 children were transferred from other hospitals in a critical condition. Five of 8 of the late referrals died as compared to none of the elective admissions. All 8 of the late referrals required mechanical ventilation as against 3 of the 17 elective admissions. Mean duration of PICU stay in the late referrals was 27 days as compared to 15 days in the elective admissions. The authors concur with previously published reports, that early use of IVIG could reduce the mortality and the need for intubation and mechanical ventilation.

    This study aimed to evaluate the efficacy, cost, and effects of anti-D immunoglobulin (anti-D Ig), methylprednisolone, or intravenous immunoglobulin (IVIG) therapy on the development of chronic disease in children who are Rh-positive with diagnosed immune thrombocytopenic purpura (ITP). Children with newly diagnosed ITP and platelet count D Ig (50 μg/kg), methylprednisolone (2 mg/kg/day), or IVIG (0.4 g/kg/day, 5 days). Sixty children with a mean age of 6.7 years were divided into three equal groups. No difference was observed between platelet counts before treatment and on day 3 of treatment. However, platelet counts at day 7 were lower in the methylprednisolone group than in the IVIG group (P = 0.03). In the anti-D Ig group, hemoglobin and hematocrit levels were significantly lower at the end of treatment (P D Ig group, 35% of the methylprednisolone group, and 25% of the IVIG group, but no significant difference was noted among the groups. The cost analysis revealed that the mean cost of IVIG was 7.4 times higher than anti-D Ig and 10.9 times higher than methylprednisolone. In the treatment of ITP in childhood, one 50 μg/kg dose of anti-D Ig has similar effects to IVIG and methylprednisolone. Among patients who were treated with anti-D Ig, serious anemia was not observed, and the cost of treatment was less than that of IVIG treatment.

  16. THE ROLE OF IgM-ENRICHED INTRAVENOUS IMMUNOGLOBULIN IN TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    Szabó Judit

    2014-04-01

    Full Text Available After organ transplantation, gamma globulin and intravenous immunoglobulin enriched with IgM are most frequently used in septic shock as early immune-support. If the explanted organ is infected, the transplantation, as a life-saving operation, can be performed if there is no systemic inflammation and the patient receives IgM enriched immunoglobulin prophylaxis during surgery. The period after transplantation can be divided into three parts from the infection point of view: the first month after transplantation, the first sixth months and the following six months. Infections within the first month are basically related to the surgical procedure. Because of the immunosuppressive therapy, the opportunistic and fungal infections are more common during the first sixth months. After this period, the occurrence and the type of infections are similar to that of the non-transplant population except for pulmonary infections. The latter is two to three times more frequent. This is explained by the secondary hypogammaglobulinaemia (lower blood levels of IgM and IgG which is caused by the steroids but most of mycophenolate mofetil by inhibition of the T and B lymphocyte proliferation. Septic shock develops with a continuing fall of IgM levels. Under these circumstances additional intravenous immunoglobulin therapy with IgM can be lifesaving. Besides, immunoglobulin concentrates with IgM may also be used in the case of viral infections without prophylaxis and/or without etiological therapy such as in the case of West Nile virus infection. As a result of the increase in antibiotic resistance, the application of immunotherapy, including immunoglobulins may become the mainstream in the treatment of septic shock.

    Yap, P L

    A number of episodes of non-A, non-B hepatitis (NANB) have been associated in the recent past with the administration of intravenous immunoglobulin (IGIV). It now appears that hepatitis C virus (HCV) is the cause of NANB, although not all the factors leading to HCV transmission by IGIV are completely understood. Nevertheless, based on a retrospective analysis of two episodes of HCV transmitted by anti-Rh D immunoglobulin (anti-D), cold ethanol fractionation clearly is important in ensuring viral safety; both of these intravenous anti-D preparations were manufactured without benefit of this purification step. Other episodes of HCV transmission have been associated with IGIV produced using chromatography (particularly DEAE-Sephadex chromatography), which has been used after cold ethanol fractionation to further purify immunoglobulin G. DEAE-Sephadex chromatography may have only a marginal partitioning capacity, such that infective HCV virions are not further fractionated into waste fractions. All IGIV preparations associated with HCV transmission were formulated as lyophilized preparations, which may be important in stabilizing HCV before administration to patients. The role of anti-HCV screening in improving the viral safety of IGIV preparations remains unclear, but additional viral inactivation steps, such as solvent-detergent treatment or incubation at pH 4.0, probably are required for IGIV manufactured using chromatographic procedures.

    There is a growing interest in new therapeutic strategies for the treatment of Alzheimer disease (AD) which focus on reducing the beta-amyloid peptide (Aβ) burden in the brain by sequestering plasma Aβ, a large proportion of which is bound to albumin and other proteins. This review discusses the concepts of interaction between Aβ and albumin that have given rise to AMBAR (Alzheimer's Disease Management by Albumin Replacement) project, a new multicentre, randomised, controlled clinical trial for the treatment of AD. Results from preliminary research suggest that Albutein(®) (therapeutic albumin, Grifols) contains no quantifiable levels of Aβ. Studies also show that Albutein(®) has Aβ binding capacity. On the other hand, AD entails a high level of nitro-oxidative stress associated with fibrillar aggregates of Aβ that can induce albumin modification, thus affecting its biological functions. Results from the phase ii study confirm that using therapeutic apheresis to replace endogenous albumin with Albutein(®) 5% is feasible and safe in patients with AD. This process resulted in mobilisation of Aβ and cognitive improvement in treated patients. The AMBAR study will test combination therapy with therapeutic apheresis and haemopheresis with the possible leverage effect of Albutein(®) with intravenous immunoglobulin replacement (Flebogamma(®) DIF). Cognitive, functional, and behavioural changes in patients with mild to moderate AD will be assessed. the AMBAR study represents a new therapeutic perspective for AD.

    To observe and compare the clinical curative effect of the plasma exchange (PE) and intravenous immunoglobulin (IVIg) for Guillian-Barre Syndrome (GBS). Overall, 64 adult patients with GBS for PE and IVIg treatment, respectively, and nerve function were observed pre-treatment and at 1 week/2 weeks after completion of treatment; the blood immunoglobulin, complement, fibrinogen (Fib) and monocyte percentage (MON%) were detected simultaneously. After PE treatment, nerve function defect appeared to improve better than the IVIg group and clinical effect was better than the IVIg group. Treatment effective rates of the two groups after 2 weeks, respectively, are 96 and 79%. PE and IVIg can significantly reduce the GBS patients' blood immunoglobulin IgG, IgA, IgM, C3 and C4, but these were significantly lower in the PE group than in the IVIg group. Fib and MON% were significantly lower in the PE group than in the IVIg group. Both PE and IVIg have a high response as therapy and are reasonable therapeutic options for GBS. However, PE treatment has a more significantly curative effect, as it can effectively improve symptoms and be helpful in the early rehabilitation of patients. © 2014 British Blood Transfusion Society.

    Full Text Available Nonparaneoplastic opsoclonus–myoclonus ataxia syndrome is a rare neuroinflammatory condition featured by opsoclonus, myoclonus, ataxia, and cognitive behavioral disturbance. The authors report an observation of enterovirus 71-associated opsoclonus–myoclonus ataxia syndrome evolving toward full recovery on intravenous intravenous immunoglobulin (IG treatment. Based on this case report, enterovirus 71 should be added to the list of infectious agents likely involved in opsoclonus–myoclonus ataxia syndrome, including the emerging subgroup of opsoclonus–myoclonus ataxia syndrome recovering without aggressive or prolonged immunosuppressive intervention. Further studies are mandatory to define the precise role, incidence, treatment, and outcome of enterovirus 71 and other infectious agents in benign forms of opsoclonus–myoclonus ataxia syndrome.

    Drug-induced hemolytic anemia is an immune-mediated phenomenon that leads to the destruction of red blood cells. Here, we present a case of life-threatening ceftriaxone-induced hemolytic anemia (CIHA) in a previously healthy 3-year-old girl. We also reviewed the literature to summarize the clinical features and treatment of hemolytic anemia. Acute hemolysis is a rare side effect of ceftriaxone therapy associated with high mortality. Our patient had a sudden loss of consciousness with macroscopic hematuria and her hemoglobin dropped from 10.2 to 2.2 g/dl over 4 hours, indicating that the patient had life-threatening hemolysis after an intravascular dose of ceftriaxone who had previously been treated with ceftriaxone in intramuscular form for six days. CIHA is associated with a positive direct antiglobulin test, revealing the presence of IgG in all cases and C3d in most cases. Our patient's direct antiglobulin test was positive for IgG (3+) and for C3d (4+). The case was managed successfully with supportive measures and intravenous immunoglobulin therapy. Ceftriaxone is used very frequently in children; an early diagnosis and proper treatment of hemolytic anemia are essential to improve the patient outcome. The pathophysiological mechanism is the same as for non-drug autoimmune hemolytic anemia. However, there is still no consensus treatment for CIHA. Intravenous immunoglobulin can be used in clinical emergencies, such as our case, or in refractory cases.

    Full Text Available Intravenous immunoglobulins (IVIGs, a mixture of variable amounts of proteins (albumin, IgG, IgM, IgA, and IgE antibodies, as well as salt, sugar, solvents, and detergents, are successfully used to treat a variety of dermatological disorders. For decades, IVIGs have been administered for treatment of infectious diseases and immune deficiencies, since they contain natural antibodies that represent a first-line defense against pathogens. Today their indication has expanded, including the off-label therapy for a variety of autoimmune and inflammatory diseases. In dermatology, IVIGs are administered for treatment of different disorders at different therapeutic regimens, mostly with higher doses then those administered for treatment of infectious diseases. The aim of this prospective review is to highlight the indications, effectiveness, side effects, and perspectives of the systemic treatment with IVIGs for patients with severe, life-threatening, and resistant to conventional therapies autoimmune or inflammatory dermatoses.

    Five patients treated with intraperitoneal 131I-labeled mouse monoclonal antibody for ovarian cancer also received i.v. exogenous polyclonal human anti-murine immunoglobulin antibody. The pharmacokinetics of 131I-labeled monoclonal antibody in these patients were compared with those of 28 other patients receiving i.p.-radiolabeled monoclonal antibody for the first time without exogenous human anti-murine immunoglobulin, and who had no preexisting endogenous human anti-murine immunoglobulin antibody. Patients receiving i.v. human anti-murine immunoglobulin antibody demonstrated a rapid clearance of 131I-labeled monoclonal antibody from their circulation. The (mean) maximum 131I blood content was 11.4% of the injected activity in patients receiving human anti-murine immunoglobulin antibody compared to 23.3% in patients not given human anti-murine immunoglobulin antibody. Intravenous human anti-murine immunoglobulin antibody decreased the radiation dose to bone marrow (from 131I-labeled monoclonal antibody in the vascular compartment) 4-fold. Following the injection of human anti-murine immunoglobulin antibody, 131I-monoclonal/human anti-murine immunoglobulin antibody immune complexes were rapidly transported to the liver. Antibody dehalogenation in the liver was rapid, with 87% of the injected 131I excreted in 5 days. Despite the efficient hepatic uptake of immune complexes, dehalogenation of monoclonal antibody was so rapid that the radiation dose to liver parenchyma from circulating 131I was decreased 4-fold rather than increased. All patients developed endogenous human anti-murine immunoglobulin antibody 2 to 3 weeks after treatment

    Common variable immunodeficiency (CVID) represents a large heterogeneous group of antibody-deficiency syndromes associated with a wide range of clinical features and a lack of defined causes in the realm of primary immunodeficiencies. Here, we present a case of CVID in a 62-year-old white male patient with a history of longstanding complex regional pain syndrome (CRPS). His medical history included multiple sinus infections per year and several pneumonias requiring antibiotics. He has had various back surgeries, including a laminectomy at the L4 level 1 year prior to his diagnosis. Thereafter, he underwent four sympathetic nerve blocks with minimal pain relief. Blood chemistries showed a normal white blood cell count with a normal differential, but increased erythrocyte sedimentation rate and C-reactive protein levels. Total Ig (Immunoglobulin)G was 611 mg/dL (normal 700-1,600), IgG1 was 425 mg/dL (341-894), IgG2 was 114 mg/dL (171-632), IgG3 was 14.4 mg/dL (18.4-106), and IgG4 was 7.4 mg/dL (2.4-121). IgA was 47 mg/dL (normal 70-400), IgM was 131 mg/dL (40-230), and IgE was 4.5 kU/L (post-vaccination. Upon treatment of the CVID with intravenous immunoglobulin, the patient's pain levels were significantly decreased and have been maintained for more than 2 years. Therefore, immunoglobulin therapy appears to have been beneficial in the treatment of the patient's symptoms of CRPS, including pain. Additional studies investigating the mechanism by which immunoglobulin therapy may reduce the inflammation and pain of CRPS are needed.

    Full Text Available We aimed to determine the effects of treatment with intravenous immunoglobulin on bacterial infections in patients with hypogammaglobulinemia (HGG after lung transplantation.We performed a randomized, double-blind, placebo-controlled two-period crossover trial of immune globulin intravenous (IVIG, 10% Purified (Gamunex, Bayer, Elkhart, IN monthly in eleven adults who had undergone lung transplantation more than three months previously. We randomized study participants to three doses of IVIG (or 0.1% albumin solution (placebo given four weeks apart followed by a twelve week washout and then three doses of placebo (or IVIG. The primary outcome was the number of bacterial infections within each treatment period.IVIG had no effect on the number of bacterial infections during the treatment period (3 during IVIG and 1 during placebo; odds ratio 3.5, 95% confidence interval 0.4 to 27.6, p = 0.24. There were no effects on other infections, use of antibiotics, or lung function. IVIG significantly increased trough IgG levels at all time points (least square means, 765.3 mg/dl during IVIG and 486.3 mg/dl during placebo, p<0.001. Four serious adverse events (resulting in hospitalization occurred during the treatment periods (3 during active treatment and 1 during the placebo period, p = 0.37. Chills, flushing, and nausea occurred during one infusion of IVIG.Treatment with IVIG did not reduce the short-term risk of bacterial infection in patients with HGG after lung transplantation. The clinical efficacy of immunoglobulin supplementation in HGG related to lung transplantation over the long term or with recurrent infections is unknown.Clinicaltrials.gov NCT00115778.

    Full Text Available Introduction: Direct costs for treating Guillain-Barré Syndrome (GBS represent a significant financial burden to public hospitals. Few studies compared the cost of plasma exchange (PE treatment with human intravenous immunoglobulin (IVIg. Objectives: To compare the cost of two therapies for GBS: IVIg and PE. Secondary objective was to evaluate compliance to IVIg prescription guidelines of the Pharmacy and Therapeutics Committee (PTC. Methods: A cross-sectional study included 25 patients with GBS admitted in a university affiliated hospital from June, 2003 through June, 2008. The costs of IVIg (n=20 and PE (n=5 were evaluated through the cost minimization method, considering direct medical costs yield by the management of the institution. Patients receiving treatments other than PE or IVIg were excluded. Data were collected by medical records review. Clinical endpoint was disability on discharge, established by the 7-point scale of Hughes. Compliance to the PTC guidelines was evaluated considering the dose and prescription regime of IVIg. Results: Twenty-five participants, ranging from 2 to 70 years of age, were included. No difference occurred in any medical variables related to the treatment or in the main clinical outcome measured by the Hughes’ scale. The mean direct cost of PE treatment was US$ 6,059± 1,701 per patient, and the same expense for IVIg was US$ 18,344±12,259 (P = 0.035. Total inpatient cost was US$ 25,730± 18,714 in the PE group, and 34,768± 27,766 (p=0.530 in the IVIg group. Conclusions: In a university-based hospital, PE is equally effective and less expensive than IVIg to treat GBS.

    A 7-year-old girl had presented with high body temperature and joint pain which continued for 3 days. Because of the prolonged history of unexplained fever, rash, bilateral nonpurulent conjunctival injection, oropharyngeal erythema, strawberry tongue, and extreme of age, incomplete Kawasaki disease was considered and started on an intravenous immunoglobulin infusion. Six days after this treatment, patient was referred to eye clinic with decreased vision and photophobia. Visual acuity was reduced to 20/40 in both eyes. Slit-lamp examination revealed bilateral diffuse corneal punctate epitheliopathy and anterior stromal haze. Corneal epitheliopathy seemed like crystal deposits. One day after presentation, mild anterior uveitis was added to clinical picture. All ocular findings disappeared in one week with topical steroid and unpreserved artificial tear drops. We present a case who was diagnosed as incomplete Kawasaki disease along with bilateral diffuse crystalline-like keratopathy. We supposed that unusual ocular presentation may be associated with intravenous immunoglobulin treatment.

    Full Text Available Much attention has been placed recently in transplantation in highly HLA-sensitized patients. In attempts to remove these antibodies and enable successful renal transplantation, several approaches have been developed. Intravenous immunoglobulin (IVIG was found to be effective in the treatment of autoimmune and inflammatory disorders (e. g. Kawasaki disease, Guillain-Barre syndrome. Recently, a beneficial effect of IVIG on the reduc- tion of anti-HLA antibodies was described. The anti-inflammatory effect of IVIG provides hopeful opportunities in antibody-mediated rejection (AMR management. There are several protocols of IVIG administration for pre-transplant desensitization and AMR treatment: high-dose IVIG, low-dose IVIG + plasmapheresis, IVIG + plasmapheresis + rituximab. These advancements have enabled transplantation in patients previously considered untransplantable and in concert with new diagnostic techniques has resulted in new approaches to management of AMR. 

  13. Non-ST Elevation Myocardial Infraction after High Dose Intravenous Immunoglobulin Infusion

    2009-01-01

    Full Text Available Intravenous immunoglobulins (IVIgs are used for several indications, including autoimmune conditions. IVIg treatment is associated with several possible adverse reactions including induction of a hypercoagulable state. We report a 76-year-old woman treated with IVIg for myasthenia gravis, which developed chest pain and weakness following IVIg infusion. The symptoms were associated with ST segment depression in V4–6 and elevated troponin levels. The patient was diagnosed with non-ST elevation myocardial infarction (NSTEMI. The patient had no significant risk factor besides age and a cardiac perfusion scan was interpreted as normal (the patient refused to undergo cardiac catheterization. This case is compatible with IVIg-induced hypercoagulability resulting in NSTEMI. Cardiac evaluation should therefore be considered prior to initiation of IVIg treatment especially in patients with multiple cardiovascular risks.

    A 63-year-old female with no significant past medical history was presented with a 5-day history of progressive opsoclonus-myoclonus, headaches, and fevers. Her workup was significant only for positive West-Nile Virus serum serologies. She received a 2-day course of intravenous immunoglobulin (IvIG). At an 8-week follow up, she had a complete neurological remission. Adult-onset opsoclonus-myoclonus syndrome is a rare condition for which paraneoplastic and infectious causes have been attributed. To our knowledge, this is the first case reported of opsoclonus-myoclonus secondary to West-Nile Virus treated with intravenous immunoglobulin monotherapy.

    Because immune mediated mechanisms are suspected in epileptogenesis, IVIg and corticosteroids have been used as alternatives to treat refractory seizures. We present our experience treating intractable epileptic children with IVIg and prednisone. Children with intractable epilepsy treated with prednisone or IVIg between 2005-2016 were reviewed retrospectively. Children with infantile spasms and autoimmune epilepsy were excluded. Data analyzed include epilepsy type and etiology, duration of epilepsy prior to treatment, seizure outcome, time to best seizure outcome, and adverse effects. Fifty-one patients were included: 26 received IVIg; 25 received prednisone. Etiologies were similar between cohorts: genetic (13 IVIg; 10 prednisone), lesional (8 IVIg; 7 prednisone), and unknown (5 IVIg; 8 prednisone). In the prednisone cohort, 92.0% had generalized epilepsy compared to 61.5% for IVIg. Among the IVIg treated, 84.6% responded (10 genetic, 4 unknown, and 8 lesional) with mean seizure reduction of 77.3% and mean time to best response of 9.8 weeks. With prednisone, 24.0% responded (2 genetic, 3 unknown, and 1 lesional) with a mean seizure reduction of 95.0% and mean time to best response of 2.7 weeks. Adverse effects occurred in 2 and 16 patients treated with IVIg and prednisone, respectively. The difference in responders and seizure reduction was statistically significant (p<0.0001 and p=0.001, respectively). IVIg had greater responders and lower adverse effects and honeymoon effect. This response was independent of epilepsy type, etiology, and duration suggesting different mechanisms of action between prednisone and IVIg and a common, reversible, immune-mediated pathway to intractability.

    We hypothesized that subcutaneous administration of immunoglobulins (SCIG) in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is feasible, safe and superior to treatment with saline for the performance of muscle strength. Thirty patients with motor involvement in maintenance therapy with intravenous immunoglobulin (IVIG) fulfilling the EFNS/PNS criteria for CIDP, aged 18-80 years, were randomized either to SCIG at a dose corresponding to their pre-study IVIG dose or to subcutaneous saline given twice or thrice weekly for 12 weeks at home. At the start and end of the trial as well as 2 weeks before (-2, 0, 10, 12 weeks), isokinetic strength performance of four predetermined and weakened muscle groups was measured. Also, an Overall Disability Sum Score (ODSS), 40-m-walking test (40-MWT), nine-hole-peg test, Neurological Impairment Score (NIS), Medical Research Council (MRC) score, grip strength, standardized electrophysiological recordings from three nerves, and plasma IgG levels were evaluated. SCIG treatment was well tolerated in all 14 patients. Six patients complained of mild side-effects at the injection site. In the SCIG group there was an increase of isokinetic muscle strength of 5.5 ± 9.5% (P < 0.05) as compared with a decline of 14.4 ± 20.3% (P < 0.05) in the placebo group; the difference between the two groups being significant (P < 0.01). ODSS, NIS, MRC, grip strength and 40-MWT improved following SCIG versus saline. SCIG treatment in CIDP is feasible, safe and effective, and seems an attractive alternative to IVIG. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

    The therapeutic efficacy of high-dose intravenous immunoglobulin in systemic lupus erythematosus (SLE) patients is well established. However, side effects might limit its use and lead to the consideration of therapeutic alternatives, such as the subcutaneous formulation of immunoglobulin, which has been used in some patients with other autoimmune diseases. We report a case of SLE refractory to classical therapies. High-dose intravenous immunoglobulin was effective, but gave rise to significant side effects. The patient was successfully treated with subcutaneous human immunoglobulin, achieving and maintaining clinical and laboratory remission. A lower immunoglobulin dose was needed and no side effects were observed, compared to the intravenous administration. Subcutaneous immunoglobulin could be a better-tolerated and cost-saving therapeutic option for select SLE patients. © The Author(s) 2016.

    Objective: To compare the therapeutic outcomes of plasmapheresis with intravenous immunoglobulins (IVIG) for Guillain Barre syndrome. Study Design: Randomized controlled trial. Place and Duration of Study: Medicine department; PNS Shifa Hospital Karachi from Jan 2011 to Jun 2012. Patients and Methods: Adult patients admitted to internal medicine department with the diagnosis of Guillain Barre Syndrome (GBS) fulfilling the inclusion and exclusion criteria were included after taking ethical approval and informed consent. They were randomly assigned to plasmapheresis and IVIG treatment groups. Their presenting features, investigations and management plan were followed over 6 months duration. Hughes disability scale for Guillain Barre syndrome was documented and compared at admission, 4 weeks, 12 weeks and 6 months by non-parametric tests via SPSS version 17. Results: Total 36 patients (31 males and 5 females) were included. Mean age was 37 ± 15 (18-70) years, mean duration of symptoms 11.6 ± 12.7 days. Plasmapheresis and IVIG groups were comparable with respect to age and gender (p>0.05). Significant improvement of mean disability score was observed in each group from baseline score (p<0.0005). At specified intervals, comparison between the two groups in terms of mean improvement in disability scores showed significant improvement at 4 weeks (p<0.05) in IVIG group as compared to plasmapheresis group; however on further observation at 12 weeks and 6 months, mean improvement was comparable between two groups with no significant difference (p>0.05). There was no significant difference in need for assisted ventilation between two groups (p>0.05). Variants of GBS observed were AIDP (50%), AMAN (31%) and AMSAN (19%). Conclusion: Our study suggests that both plasmapheresis and intravenous immunoglobulins are useful and effective modes of treatment for Guillain Barre Syndrome. Significant short term improvement was observed in the IVIG group at 4 weeks of treatment; however

    Full Text Available Impetigo herpetiformis (IH, if left untreated, is associated with a high rate of perinatal morbidity and mortality and may lead to the decision of termination of pregnancy. There are various and effective therapeutic agents available for the treatment of the disease. A 23-year-old woman with a history of plaque psoriasis presented with a sudden generalized pustular eruption on the 25th week of her first gestation. The diagnosis was made based on the clinical and histopathological findings. The patient was treated with systemic prednisolone (2 mg/kg/d first and, cyclosporine A (3 mg/kg/d was added to the treatment after two weeks because prednisolone was not effective alone. The lesions did not regress despite four weeks of combined treatment with prednisolone and cyclosporine. Intravenous immunoglobuline (IVIG (0.3 g/kg/d, 6 days was added on the 30th week of gestation and resulted in regression of cutaneous rashes. On the 33rd week of gestation, IVIG (0.7 g/kg/d, 3 days was repeated due to reactivation of pustules, and an improvement was observed. In this case report, we called attention to IVIG therapy in IH, for having the pregnancy continued enough for the fetal maturation before the delivery.

    Full Text Available Background Kawasaki Disease (KD is a vasculitis with multi-organ involvementof unknown etiology; it is the most common cause of pediatric-heart diseases in developed countries. Treatment with Intravenous Immunoglobulin (IVIG prevents coronary artery lesions; although there are some IVIG-resistant cases, combination therapy with corticosteroids and IVIG is one of the recommendations for treatment of these cases. The aim of this study was to compare these three options for treatment of Kawasaki Disease and to evaluate their ability to deal with coronary artery complication of Kawasaki Disease. Materials and Methods A prospective cross- sectional study of hospitalized cases of Kawasaki Disease, conducted in pediatric department of Imam Reza hospital, Mashhad-Iran, during 2013 to 2015 (18 months. Based on demographic and clinical data of these patients, children with high risk of unresponsiveness to IVIG therapy (based on Harada score, were determined and treated with IVIG and corticosteroids- combination initially. Follow-up patients for heart complications were 6 weeks. Results Twenty five patients (89.2% out of total 28 hospitalized patients in this period of time who fulfilled diagnostic criteria were considered as complete Kawasaki Disease. Coronary Artery Lesions (CALs were shown in 4 patients during the follow-up period, with high risk in patients with incomplete presentation (33.3% versus 12%, P

    Flebogamma 5% dual inactivation and filtration (DIF), a new 5% liquid intravenous immunoglobulin with a stability of 2 years when stored at temperatures between 2 and 30 degrees C, has been developed. This new product is the result of the accumulated experience provided by Flebogamma, with more than 30 million grams administered since 1992 in Europe and the United States, and the implementation of the latest technology to improve Flebogamma even more by increasing its viral safety margin further. In addition to the specific inactivation stage for Flebogamma 5% (pasteurization), the new process includes a solvent-detergent treatment and nanofiltration through a Planova filter down to 20 nm. The preparation presents a mean purity of 99.6 +/- 0.2% with a correct chromatographic profile. Percentage values of immunoglobulin (Ig)G subclasses are equivalent to the physiological values of normal serum. The content in IgA as well as other possible impurities is very low, and the product presents a mean result of 109 +/- 5% in the Fc fragment functionality assay, demonstrating the integrity of the IgG molecule. The functionality is also reflected in neutralization tests carried out against poliomyelitis, diphtheria, measles and vaccinia which, apart from the antibody titres determined by enzyme-linked immunosorbent assay, guarantees that antibodies are capable of reacting against these pathogens. Regarding safety, the combination of multiple methods with capacity to inactivate or remove biological agents which include chemical inactivation, heat inactivation, nanofiltration and precipitations, with very different mechanisms of action, provides Flebogamma 5% DIF very wide margins of safety regarding to potential pathogens.

    Full Text Available The article describes a case of late diagnosis of mucocutaneous lymphonodular syndrome (Kawasaki syndrome. At the beginning of the therapy, the child had fever, conjunctivitis, stomatitis, rash, solid swelling of hands and feet, and coronaritis with the development of aneurysms. The article describes the successful use of normal human immunoglobulin for intravenous administration at a dose of 2 g/kg body weight per course in combination with acetylsalicylic acid at the dose of 80 mg/kg per day. After 3 days of treatment, the rash disappeared; limb swelling and symptoms of conjunctivitis significantly reduced; and laboratory parameters of disease activity became normal (erythrocyte sedimentation rate, C-reactive protein concentration. After 3 months, inflammation in the coronary arteries was stopped. After 6 months, a regression of coronary artery aneurysms was recorded. No adverse effects during the immunoglobulin therapy were observed.

    Vitamin D is associated with various pathological conditions such as cardiovascular diseases and cancer. We investigated the relationship between vitamin D and Kawasaki disease (KD). We performed a retrospective review of the medical records of patients with KD between February 2013 and March 2016 in Daegu Fatima Hospital. Study participants were grouped according to vitamin D serum concentration. Group 1 included patients with 25(OH)-vitamin D ≥20 ng/mL. Group 2 included patients with 25(OH)-vitamin D immunoglobulin was more frequent in group 2 ( P =0.023). No significant difference in the incidence of coronary artery complications was observed. Low vitamin D levels are associated with resistance to intravenous immunoglobulin therapy in KD. Vitamin D deficiency might be a risk factor for immunoglobulin resistance in KD.

    Neonatal appendicitis is a rare clinical condition that may cause high morbidity and mortality if diagnosis is delayed. There is usually an underlying disease; it can also be a localized form of necrotizing enterocolitis. Here, we present a term neonate who was treated with intravenous immunoglobulin because of severe isoimmune hemolytic jaundice. The patient developed abdominal symptoms within 10 hours of therapy, was diagnosed with acute perforated appendicitis and completely recovered after surgery. (author)

  8. Does intravenous immunoglobulin therapy prolong immunodeficiency in transient hypogammaglobulinemia of infancy?

    Full Text Available Transient hypogammaglobulinemia of infancy (THI is characterized by recurrent infections and one or more reduced serum immunoglobulin levels. Typically, THI patients recover spontaneously, mostly within 30-40 months of age, but sometimes recovery may be delayed until 5-6 years of age. The use of intravenous immunoglobulin (IVIg as an alternative to antibiotic prophylaxis remains contraversial also in symptomatic THI patients. In fact, some authors believe that IVIg therapy may cause a delay in the maturation of the humoral immune system because of the interference from passively transfered antibodies. The aim of this study was to investigate the effect of IVIg replacement on recovery from immunodeficiency in THI patients and determine new parameters in order to include these patients in IVIg therapy groups. In this retrospective study, 43 patients (65% received IVIg replacement therapy while 23 patients (34.8% showed spontaneous normalization without IVIg. The percentages of patients who had more than six times the number of febrile infections in a year decreased from 91% to 21% in the group receiving IVIg treatment. At admission, before being recruited to IVIg therapy, serum immunoglobulin G (IgG levels and anti-hemophilus B (Hib antibody titers were found to be significantly low in cases who were selected for IVIg replacement. The percentages of patients who did not have protective levels of anti-Hib, anti-rubella or anti-rubeola-IgG were also significantly high in IVIg cases. There was no statistically significant difference in the age at which IgG levels normalized between the IVIg and the non-IVIg group. Patients in the IVIg group and non-IVIg group reached normal IgG levels at the age of 42.9±22.0 and 40.7±19.8 months, respectively. In conclusion, IVIg infusions do not cause a delay in the maturation of the immune system in THI patients. Besides the well-established criteria, very low and non-protective specific antibody responses

    The antiphospholipid syndrome (APS) is defined by the occurrence of venous and arterial thromboses and recurrent fetal losses, frequently accompanied by a moderate thrombocytopenia, in the presence of antiphospholipid antibodies (aPL), namely lupus anticoagulant (LA), anticardiolipin antibodies (aCL), or anti-β2 glycoprotein-I (β2GPI) antibodies. The current mainstay of treatment for thrombotic APS is heparin followed by long-term anticoagulation, while in obstetric APS, the accepted first-line treatment consists in low-dose aspirin (LDA) plus prophylactic unfractionated or low-molecular-weight heparin (LMWH). Recently, new emerging treatment modalities, including intravenous immunoglobulins (IVIG), have been implemented to manage APS refractory to conventional therapy. The objective of this review is to summarize the currently available information on the IVIG therapy in APS, focusing on the use of IVIG in the obstetric form, CAPS and on primary or secondary thromboprophylaxis. We analyzed 35 studies, reporting the effects of IVIG in APS patients, and we discussed their results. IVIG in obstetric APS seem to be very useful in selected situations (patients not responsive to the conventional treatment, concomitant autoimmune manifestations or infections or patients in whom anticoagulation is contraindicated). IVIG treatment represents an important component of the combination therapy of CAPS and they could be useful, in addition to the standard therapy, to prevent recurrent thrombosis in APS patients refractory to conventional anticoagulant treatment. Anyway, in some cases we also found controversial results that claim the need of further well-designed studies to definitely state the efficacy and tolerability of IVIG in CAPS, obstetric and non-APS.

  11. Role of the Egami Score in Predicting Intravenous Immunoglobulin Resistance in Kawasaki Disease Among Different Ethnicities.

    Science.gov (United States)

    Loomba, Rohit S; Raskin, Alexander; Gudausky, Todd M; Kirkpatrick, Edward

    Early treatment with intravenous immunoglobulin (IVIG) is necessary to help reduce the risk of coronary artery abnormalities, such as coronary artery aneurysms and to help alleviate symptoms, in Kawasaki disease. Some patients, however, do not respond to an initial dose of IVIG and require additional doses. Prediction of these IVIG nonresponders may be of assistance in altering initial therapy to make it more effective. The Egami score has been validated in the Japanese population to predict IVIG nonresponders but has shown to be ineffective in US populations. This study evaluates the Egami score in a Midwest US population, subdividing patients by race and the diagnosis of typical or atypical type of Kawasaki disease. Patients were included in the study if they met criteria for Kawasaki disease and received IVIG in the inpatient setting. A total of 182 patients were studied, and in all studied groups, the Egami score had poor sensitivity at predicting IVIG nonresponders. Sensitivity of the score differed between races and differed between typical and atypical Kawasaki disease. The Egami score, as well as other systems, have been validated to predict IVIG nonresponders. These, however, lack sensitivity in the US population. Other scores developed in the United States have also lacked sensitivity, likely due to the absence of race or Kawasaki disease classification as variables. The development of a sensitive scoring system to predict IVIG nonresponders in US populations will require the incorporation of race and Kawasaki disease classification, factors that seem to alter IVIG response.

  12. Critical review of the role of intravenous immunoglobulins in idiopathic inflammatory myopathies.

    2017-02-01

    The aim of this review was to summarize key findings from the literature concerning the therapeutic role of intravenous immunoglobulins (IVIg) in idiopathic inflammatory myopathies (IIM), dissecting the evidence according to disease subtype and treatment indication, and to review the evidence relating to the mechanism of action of IVIg in IIM to ascertain rationale for continued research. Medline (Ovid) and Pubmed databases were searched from inception to July 2016 using relevant keywords. Original and review articles were retrieved for full-text review. Bibliographies of selected articles were also hand-searched for additional references. Data were summarized qualitatively and in tabular form. The efficacy of IVIg in IIM is supported by 3 randomized controlled trials, involving dermatomyositis and polymyositis subjects, in refractory, relapsed, or steroid-dependent disease, as well as part of first-line therapy in elderly dermatomyositis subjects. Other indications for IVIg are supported by uncontrolled evidence only. Limitations of studies include open, uncontrolled or retrospective study designs, small and selected samples, short-term follow-up and ad hoc outcome measures. Despite the limited evidence, there is strong biological plausibility for the role of IVIg in IIM. Robust, controlled evidence to support the use of IVIg using validated outcome measures is urgently required to guide therapeutic decision-making and maximize outcomes in IIM.

    1999-01-01

    Following the second series of intravenous human immunoglobulins (IVIg; 0.4 g/kg) prescribed to treat a sensorimotor polyneuritis, a 28-year-old woman developed pompholyx that recurred after each of the following monthly treatments with IVIg. During the administration of the 10th series, the patient developed a typical baboon syndrome. Immunohistochemical studies of a skin biopsy revealed an unexpected epidermal expression of P-selectin, usually expressed by endothelial cells. Patch, prick and intradermal tests performed with IVIg on the back, arms and buttocks gave negative results on immediate and delayed readings. IVIg were re-administered, with the informed consent of the patient, and induced a generalized maculopapular rash. This is the first reported case of baboon syndrome induced by IVIg. Although extensive skin testing was performed, all test sites remained negative. We wonder whether IVIg could reproduce immunological mechanisms involved in the 3 types of systemic contact dermatitis (pompholyx, baboon syndrome and maculopapular rash), including the epidermal expression of P-selectin.

    2015-10-01

    Full Text Available  Background: Drug use evaluation (DUE aims at improving the patients’ care. Studying the administration pattern of intravenous immunoglobulin (IVIG is an important research topic due to its significant role in the treatment and controlling of many disorders, high prices, and limited availability of this drug.  Methods:This observational cross-sectional study was conducted at Shahid Sadoughi Hospital in Yazd, central Iran, from May to September 2014. The orders of different wards in the hospital for IVIG given to the hospital central pharmacy were surveyed. Also, a special form developed for evaluation the method of administration. The related physician and nurse were consulted on drug complications and the causes. Finally, the gleaned data were compared to the available standards on the prescription and administration of IVIG.Results:A total of 75 patients received IVIG during this study. 58.7% of the prescriptions belonged to the cases approved by Food and Drug Administration (FDA. The most frequent cause of the use of IVIG was idiopathic thrombocytopenic purpura (ITP. The rate and dose of administration was suitable in most of the patients, yet, the measurement of laboratory parameters required for IVIG were observed in only a few cases. Complications occurred in 26.7% of the patients receiving it, which was mostly related to infusion-related reactions. On the whole, 3922 g IVIG was used during this study of which 1848 g belonged to the cases approved by FDA.Conclusion:Regarding the high costs of IVIG, complications, and limited information on the quality of the effect of this drug in the treatment of many cases, physicians should be cautious enough with its appropriate use. Besides, the presence of a clinical pharmacist in the health-care team not only improves the quality of drug therapy and treatment results, but also plays an important part in decreasing the treatment costs for the patients.

    Immunoadsorption (IA) is increasingly used instead of plasma exchange due to lower risk of side effects and a higher selectivity. As a consequence of the reduction of immunoglobulins (Ig), the rate of infectious complications might increase in those patients. We therefore aimed to investigate the infection rate following IA without intravenous IG (IVIG) substitution in our apheresis center, where patients do not receive IVIG on a regular basis. We conducted a retrospective analysis of the IA treatments performed between 2010 and 2015 without IVIG substitution and collected data on patient age, diagnosis, number of IA treatments, serum levels of Ig, total protein, albumin, C-reactive protein (CRP) and infectious complications that occurred within 2 months after the IA treatment cycle. A total number of 52 patients (27 females) received at least 5 IA sessions using the following adsorbers: TheraSorb™-Ig (n = 3), TheraSorb™-Ig flex (n = 44), TheraSorb™ Ig pro (n = 1) and TheraSorb™-IgE (n = 5). The median number of treatment sessions was 8.8 [range 5-16], the median IgG reduction was 82 [11-99] %. Serum albumin was decreased by 8%. The median CRP levels remained normal until the end of therapy and within 2 months after that (3.10 and 4.30 mg/L respectively). Only 4 patients had infections (7.7%). Three of them received additional immunosuppressive therapy. Immunoadsorption leads to a significant reduction of IgG. CRP as inflammatory marker is not affected. Even without substitution of IVIG the complication rate directly linked with IA is low and questionable. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although pulse-dose dexamethasone is increasingly favored for treating pediatric opsoclonus-myoclonus syndrome (OMS), and multimodal immunotherapy is associated with improved clinical response, there have been no neuroimmunologic studies of dexamethasone-based multimodal disease-modifying therapy. In this observational retrospective study, 19 children with OMS (with or without associated neuroblastoma) underwent multibiomarker evaluation for neuroinflammation. Nine children of varying OMS severity, duration, and treatment status were treated empirically with pulse dexamethasone, intravenous immunoglobulin (IVIg), and rituximab combination immunotherapy (DEXIR-CI). Another 10 children on dexamethasone alone or with IVIg at initial evaluation only provided a comparison group. Motor severity (total score) was scored rater-blinded via videotapes using the validated OMS Evaluation Scale. DEXIR-CI was associated with a 69% reduction in group total score (P = 0.004) and was clinically well tolerated. Patients given the dexamethasone combination exhibited significantly lowered B cell frequencies in cerebrospinal fluid (-94%) and blood (-76%), normalizing the cerebrospinal fluid B cell percentage. The number of patients with positive inflammatory markers dropped 87% (P = 0.002) as did the number of markers. Cerebrospinal fluid oligoclonal bands were positive in four of nine pretreatment patients but zero of six post-treatment patients. In the comparison group, partial response to dexamethasone alone or with IVIg was associated with multiple positive markers for neuroinflammation despite an average of seven months of treatment. Multimechanistic dexamethasone-based combination immunotherapy increases the therapeutic armamentarium for OMS, providing a viable option for less severely affected individuals. Partial response to dexamethasone with or without IVIg is indicative of ongoing neuroinflammation and should be treated promptly and accordingly. Copyright © 2017

    Immunoglobulin therapy can be used to treat a wide variety of diseases. However, intravenous immunoglobin products can cause several adverse reactions, including hemolysis. The objective of this study was to determine the extent of anemia and hemolysis after high dose intravenous immunoglobin (2g/kg) and its relationship to the ABO blood type system and hemolytic anemia blood parameters in pediatric patients. Incidence of 'Intravenous immunoglobulin related hemolysis' was %19 (6/31) after high dose intravenous immunoglobulin therapy. The blood parameters were measured before IVIG infusion (1-24h before infusion) and 3-10 days after the first day of infusion. In terms of decrease in Hb levels; decline of 2g/dL (severe hemolysis) in 4 patients (12.9%) after infusion. The decrease in hemoglobin, haptoglobin levels, the increase of reticulocyte count or direct bilirubin were statistically significant after infusion. Five of 6 hemolysis patients had non-O blood group, however statistically significant difference was not noted between these two groups. Also, intravenous immunoglobulin-related hemolysis was determined significantly higher in female than male patients. Mild to moderate hemolysis may be undetected after infusion and the true incidence of such reactions is difficult to document without careful clinical and laboratory follow-up. A careful risk assessment analysis should be performed before intravenous immunoglobulin infusion. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Intravenous immunoglobulin (IVIg) is a polyclonal immunoglobulin G preparation with potent immunomodulatory properties. The mode of action of IVIg has been investigated in multiple disease states, with various mechanisms described to account for its benefits. Recent data indicate that IVIg increases both the number and the suppressive capacity of regulatory T cells, a subpopulation of T cells that are essential for immune homeostasis. IVIg alters dendritic cell function, cytokine and chemokine networks, and T lymphocytes, leading to development of regulatory T cells. The ability of IVIg to influence Treg induction has been shown both in animal models and in human diseases. In this review, we discuss data on the potential mechanisms contributing to the interaction between IVIg and the regulatory T-cell compartment.

    Common variable immunodeficiency (CVID) is a heterogeneous subset of immunodeficiency disorders. Recurrent bacterial infection is the main feature of CVID, but various non-infectious complications can occur. A 42-year-old woman presented with cough and abnormal chest X-ray shadows. Laboratory tests showed remarkable hypogammaglobulinemia. Computed tomography revealed multiple consolidation and nodules on the bilateral lung fields, systemic lymphadenopathy, and splenomegaly. A surgical lung biopsy specimen provided the final diagnosis of lymphoproliferative disease in CVID, which was grouped under the term granulomatous lymphocytic interstitial lung disease. Interestingly, the lung lesions of this case resolved immediately after the initiation of intravenous immunoglobulin monotherapy.

    Cardiopulmonary manifestations of adult-onset Still's disease (AOSD) include pericarditis, pleural effusion, transient pulmonary infiltrates, pulmonary interstitial disease and myocarditis. Serositis are common but pneumonitis and myocarditis are not and bring elevated risk of mortality. They may manifest on disease onset or flares. Previously reported cases were treated with high-dose glucocorticoids and immunosupressants and, when refractory, intravenous immunoglobulin (IVIG). We report an AOSD patient whose flare presented with severe pleupneumonitis and myopericarditis and, following nonresponse to a methylprednisolone pulse, high dose of prednisone and cyclosporine A, recovered after a 2-day 1g/kg/day IVIG infusion.

    Refractory recurrent pericarditis is a major clinical challenge after colchicine failure, especially in corticosteroid-dependent patients. Human intravenous immunoglobulins (IVIGs) have been proposed as possible therapeutic options for these cases. The goal of this systematic review is to assess the efficacy and safety of IVIGs in this context. Studies reporting the use of IVIG for the treatment of recurrent pericarditis and published up to October 2014 were searched in several databases. All references found, upon initial assessment at title and abstract level for suitability, were consequently retrieved as full reports for further appraisal. Among the 18 citations retrieved, 17 reports (4 case series and 13 single case reports, with an overall population of 30 patients) were included. The mean disease duration was 14 months and the mean number of recurrences before IVIG was 3. Approximately 47% of patients had idiopathic recurrent pericarditis, 10% had an infective cause, and the remainder a systemic inflammatory disease. Nineteen out of the 30 patients (63.3%) were on corticosteroids at IVIG commencement. IVIGs were generally administered at a dose of 400-500 mg/kg/day for 5 consecutive days with repeated cycles according to the clinical response. Complications were uncommon (headache in ~3%) and not life-threatening. After a mean follow-up of approximately 33th months, recurrences occurred in 26.6% of cases after the first IVIG cycle, and 22 of the 30 patients (73.3%) were recurrence-free. Five patients (16.6%) were on corticosteroids at the end of the follow-up. IVIGs are rapidly acting, well tolerated, and efficacious steroid-sparing agents in refractory pericarditis.

  2. The Nuts and Bolts of Immunoglobulin Treatment for Antibody Deficiency.

    Science.gov (United States)

    Wasserman, Richard L

    Immunoglobulin therapy is a key element in the management of most patients with primary immunodeficiency disease. Allergist/immunologists should be familiar with the appropriate evaluation of candidates for immunoglobulin, the characteristics of immunoglobulin products, and how to use them to provide the best care to their patients. Available immunoglobulin products appear to be equally efficacious, but they are not interchangeable. Minimizing the risk of serious adverse events and controlling minor side effects is important to ideal patient care. Immunoglobulin may be administered intravenously or subcutaneously. Individualizing the choice of immunoglobulin product, mode of administration, and site of care can optimize the clinical outcome and minimize the burden of care.

    Hemolytic disease of newborn (HDN) is a condition that develops in a fetus, when the IgG molecules produced by the mother pass through the placenta and attack the fetal red blood cells. HDN can occur due to Rh and ABO incompatibilities between the mother and the fetus as well as due to other allo-immune antibodies belonging to Kell (K and k), Duffy (Fya), Kidd (Jka and Jkb), and MNS (M, N, S, and s) systems. Role of intravenous immunoglobulin in management of HDN is not clear.SARA red blood cell antigen, first discovered in 1990 is a low frequency antigen. We report, a multiparous female whose pregnancy was complicated by HDN due to anti-SARA antibodies requiring both exchange transfusion and intravenous immunoglobulin. The response was sustained after intravenous immunoglobulin (IVIG) rather than after exchange transfusion.

    2011-01-01

    Full Text Available Common variable immunodeficiency is the most common form of symptomatic primary antibody failure in adults and children. Replacement immunoglobulin is the standard treatment of these patients. By using a differential proteomic approach based on 2D-DIGE, we examined serum samples from normal donors and from matched, naive, and immunoglobulin-treated patients. The results highlighted regulated expression of serum proteins in naive patients. Among the identified proteins, clusterin/ApoJ serum levels were lower in naive patients, compared to normal subjects. This finding was validated in a wider collection of samples from newly enrolled patients. The establishment of a cellular system, based on a human hepatocyte cell line HuH7, allowed to ascertain a potential role in the regulation of CLU gene expression by immunoglobulins.

However, nationwide studies with longitudinal follow-up are still lacking. The aim of this study was to evaluate the comparative effectiveness of immunoglobulin preparations from a nationwide perspective. MATERIALS AND METHODS: This is a nationwide retrospective cohort study with a new user design. Data came from the National Health Insurance Research Database of Taiwan. From 1997 to 2008, children under 2 years old who received immunoglobulin therapy for the first time under the main diagnosis of Kawasaki disease were enrolled. The manufacturing processes were divided into β-propiolactonation, acidification and those containing IgA. The endpoints were immunoglobulin non-responsiveness, acute aneurysm, prolonged use of anti-platelets or anti-coagulants, and recurrence. RESULTS: In total, 3830 children were enrolled. β-propiolactonation had a relative risk of 1.45 (95% CI 1.08~1.94 of immunoglobulin non-responsiveness, however, the relative risks for acidification and containing IgA were non-significant. For acute aneurysms, acidification had a relative risk of 1.49 (95% CI 1.17~1.90, however the relative risks for β-propiolactonation and containing IgA were non-significant. For prolonged use of anti-platelets or anti-coagulants, β-propiolactonation had a relative risk of 1.44 (95% CI 1.18~1.76, and acidification protected against them both with a relative risk of 0.82 (95% CI 0.69~0.97, whereas the relative risk for containing IgA was non-significant. For recurrence, all three factors were non-significant. CONCLUSIONS: The effectiveness of immunoglobulin may differ among different manufacturing processes. β-propiolactonation had a higher risk of treatment failure and prolonged use of anti-platelets or anti-coagulants. Acidification may increase the risk of acute coronary aneurysms.

    Autoimmune hemolytic anemia is rare in children. First-line therapies for this disease consist of corticosteroids and intravenously administered immunoglobulin that are effective in most patients. However, a small proportion of cases (5 to 10%) is refractory to these therapies and may represent a medical emergency, especially when hemolysis is due to warm immunoglobulin M. Recently, reports of the use of rituximab in adult autoimmune diseases have shown promising results. In children, there are few studies on the use of rituximab in the treatment for autoimmune hemolytic anemia, especially on its long-term efficacy and adverse effects. Here, we report the case of a 10-year-old Tunisian girl with refractory acute autoimmune hemolytic anemia caused by warm-reactive immunoglobulin A, immunoglobulin G, immunoglobulin M, and C3d autoantibodies. First-line treatments using corticosteroids and intravenously administered immunoglobulin were ineffective in controlling her severe disease. On the other hand, she was successfully treated with rituximab. In fact, her hemolytic anemia improved rapidly and no adverse effects were observed. The case that we report in this paper shows that rituximab could be an alternative therapeutic option in severe acute autoimmune hemolytic anemia with profound hemolysis refractory to conventional treatment. Moreover, it may preclude the use of plasmapheresis in such an urgent situation with a sustained remission.

    Full Text Available A 57-year-old male presented with a 6-month history of blisters and painful erosions on the right buccal mucosa. No skin or other mucosal involvement was seen. The findings of histopathological and direct immunofluorescence examinations were sufficient for the diagnosis of oral mucous membrane pemphigoid in the context of adequate clinical correlation. No response was seen after topical therapies and oral corticosteroids or dapsone. Intravenous immunoglobulin was started and repeated every three weeks. Complete remission was achieved after three cycles and no recurrence was seen after two years of follow-up. The authors report a rare unilateral presentation of oral mucous membrane pemphigoid on the right buccal and hard palate mucosa, without additional involvement during a period of five years. Local trauma or autoimmune factors are possible etiologic factors for this rare disorder, here with unique presentation.

    Full Text Available Miller-Fisher syndrome (MFS is a rare condition characterized by the classical triad of ophthalmoplegia, ataxia, and areflexia (Fisher, 1956. It is considered a variant of Guillain-Barré syndrome (GBS with which it may overlap, or it can occur in more limited forms. We report a case of a thirty-five-year-old male who presented with a six-day history of diplopia, following a recent chest infection. On examination, he was found to have bilateral sixth nerve palsy, bilateral fourth nerve palsy, bilateral areflexical mydriasis, ataxia and total absence of reflexes. After excluding other conditions, a diagnosis of Miller-Fisher syndrome was made. The patient was administered intravenous immunoglobulin and made an uneventful recovery.

    We report a screen of plasma donors confirming that widespread use of childhood measles vaccination since 1963 resulted in a decrease in average measles virus antibody titers among plasma donors, which is reflected in intravenous immunoglobulins (IVIGs). The measles virus antibody titer, however, is a potency requirement for IVIGs, as defined in a Food and Drug Administration regulation. To mitigate the decline in measles virus antibody titers in IVIGs and to ensure consistent product release, revaccination of plasma donors was investigated as a means to boost titers. However, revaccination-induced titer increases were only about 2-fold and short-lived. © The Author 2017. Published by Oxford University Press for the Infectious Diseases Society of America.

    The use of intravenous immunoglobulin (IVIg) has been reported as an immunomodulating agent in several autoimmune diseases, including systemic lupus erythematosus (SLE). Herein we report a SLE patient with severe clinical presentation that included pericarditis, pleural effusion, nephrotic range proteinuria, leukopenia, and lymphopenia. The patient received one course of high-dose IVIg (2.8 g/kg body weight), and within a week of post-IVIg therapy, her condition significantly improved. One-month post-IVIg there were decreased proteinuria, elevated leukocytes and lymphocytes count, decrease in antinuclear and anti-dsDNA antibodies, and disappearance of pericarditis and pleuritis. This case demonstrates the efficacy of IVIg in severe SLE with various clinical manifestations.

  12. Gene expression profiling in peripheral blood mononuclear cells of patients with common variable immunodeficiency: modulation of adaptive immune response following intravenous immunoglobulin therapy.

    Marzia Dolcino

    Full Text Available BACKGROUND: Regular intravenous immunoglobulin treatment is used to replace antibody deficiency in primary immunodeficiency diseases; however the therapeutic effect seems to be related not only to antibody replacement but also to an active role in the modulation of the immune response. Common variable immunodeficiency is the most frequent primary immunodeficiency seen in clinical practice. METHODS: We have studied the effect of intravenous immunoglobulin replacement in patients with common variable immunodeficiency by evaluating the gene-expression profiles from Affimetrix HG-U133A. Some of the gene array results were validated by real time RT-PCR and by the measurement of circulating cytokines and chemokines by ELISA. Moreover we performed FACS analysis of blood mononuclear cells from the patients enrolled in the study. RESULTS: A series of genes involved in innate and acquired immune responses were markedly up- or down-modulated before therapy. Such genes included CD14, CD36, LEPR, IRF-5, RGS-1, CD38, TNFRSF25, IL-4, CXCR4, CCR3, IL-8. Most of these modulated genes showed an expression similar to that of normal controls after immunoglobulin replacement. Real time RT-PCR of selected genes and serum levels of IL-4, CXCR4 before and after therapy changed accordingly to gene array results. Interestingly, serum levels of IL-8 remained unchanged, as the corresponding gene, before and after treatment. FACS analysis showed a marked decrease of CD8+T cells and an increase of CD4+T cells following treatment. Moreover we observed a marked increase of CD23⁻CD27⁻IgM⁻IgG⁻ B cells (centrocytes. CONCLUSIONS: Our results are in accordance with previous reports and provide further support to the hypothesis that the benefits of intravenous immunoglobulin therapy are not only related to antibody replacement but also to its ability to modulate the immune response in common variable immunodeficiency.

    The development of effective, safe, liquid intravenous immunoglobulins (IVIG) preparations has represented a major therapeutic advancement in the treatment of patients with antibody deficiencies. Flebogamma 5% was the first liquid IVIG licensed in Europe that has been widely used in the treatment of immunodeficiency diseases. It has been proven to have an excellent efficacy and safety profile. Flebogamma 5% dual inactivation and filtration (DIF) is a newly developed IVIG preparation that shares formulation characteristics and identical biochemical and stability profiles with Flebogamma 5%. In addition to pasteurization, already performed in Flebogamma 5%, solvent-detergent treatment and sequential nanofiltration through filters with pore sizes of 35 nm followed by 20 nm have been added to further enhance the pathogen safety margin. The purpose of this study was to evaluate the efficacy, safety, and pharmacokinetics of Flebogamma 5% DIF for immunoglobulin replacement therapy in patients with primary immunodeficiency diseases (PID). Flebogamma 5% DIF was administered at seven clinical sites to 46 subjects with well-defined primary immunodeficiency diseases at a dose of 300-600 mg/kg every 21-28 days for 12 months. The serious bacterial infection rate was 0.021/subject/year. The incidence of adverse events considered potentially related to Flebogamma 5% DIF during or within 72 h after completing an infusion was approximately 10%. The half-life in serum of the administered IgG was around 31 days. In summary, Flebogamma 5% DIF is efficacious and safe, has good pharmacokinetic properties, is well-tolerated and maintains the profile of Flebogamma 5% for the treatment of patients with primary humoral immune deficiency diseases.

    Full Text Available The efficacy of intravenous immunoglobulins (IVIg in patients with autoimmune diseases (AID has been known for several decades. Majority of these patients received IVIg in hospital. A retrospective study was conducted in 22 centers in France to evaluate the feasibility of the administration of Tegeline, an IVIg from LFB Biomedicaments, and assess its safety at home, compared to in hospital, in patients with AID. The included patients were at least 18 years old, suffering from AID, and treated with at least 1 cycle of Tegeline at home after receiving 3 consecutive cycles of hospital-based treatment with Tegeline at a dose between 1 and 2 g/kg/cycle. Forty-six patients with AID, in most cases immune-mediated neuropathies, received a total of 138 cycles of Tegeline in hospital and then 323 at home. Forty-five drug-related adverse events occurred in 17 patients who received their cycles at home compared to 24 adverse events in hospital in 15 patients. Serious adverse events occurred in 3 patients during home treatment, but they were not life-threatening and did not lead to discontinuation of Tegeline. Forty-five patients continued their treatment with Tegeline at home or in hospital; 39 (84.8% were still receiving home treatment at the end of the study. In conclusion, the study demonstrates the good safety profile of Tegeline administered at home at high doses in patients with AID who are eligible for home administration of Tegeline.

    Patients with antibody deficiencies depend on the presence of a variety of antibody specificities in intravenous immunoglobulin (IVIG) to ensure continued protection against pathogens. Few studies have examined levels of antibodies to specific pathogens in IVIG preparations and little is known about the specific antibody levels in patients under regular IVIG treatment. The current study determined the range of antibodies to tetanus, diphtheria, measles and varicella in IVIG products and the levels of these antibodies in patients undergoing IVIG treatment. We selected 21 patients with primary antibody deficiencies who were receiving regular therapy with IVIG. Over a period of one year, we collected four blood samples from each patient (every 3 months), immediately before immunoglobulin infusion. We also collected samples from the IVIG preparation the patients received the month prior to blood collection. Antibody levels to tetanus, diphtheria, measles and varicella virus were measured in plasma and IVIG samples. Total IgG levels were determined in plasma samples. Antibody levels to tetanus, diphtheria, varicella virus and measles showed considerable variation in different IVIG lots, but they were similar when compared between commercial preparations. All patients presented with protective levels of antibodies specific for tetanus, measles and varicella. Some patients had suboptimal diphtheria antibody levels. There was a significant correlation between serum and IVIG antibodies to all pathogens, except tetanus. There was a significant correlation between diphtheria and varicella antibodies with total IgG levels, but there was no significant correlation with antibodies to tetanus or measles. The study confirmed the variation in specific antibody levels between batches of the same brand of IVIG. Apart from the most common infections to which these patients are susceptible, health care providers must be aware of other vaccine preventable diseases, which still exist

    Flebogamma 10% DIF represents an evolution of intravenous immune globulin from the previous 5% product to be administered at higher rates and with smaller infusion volumes. Pathogen safety is enhanced by the combination of multiple methods with different mechanisms of action. The objective of this study as to evaluate the efficacy, pharmacokinetics, and safety of Flebogamma 10% DIF for immunoglobulin replacement therapy in primary immunodeficiency diseases (PIDD). Flebogamma 10% DIF was administered to 46 subjects with well-defined PIDD at a dose of 300-600 mg/kg every 21-28 days for 12 months. Serious bacterial infection rate was 0.025/subject/year. Half-life in serum of the administered IgG was approximately 35 days. No serious treatment-related adverse event (AE) occurred in any patient. Most of the potentially treatment-related AEs occurred during the infusion, accounting for 20% of the 601 infusions administered. Flebogamma 10% DIF is efficacious and safe, has adequate pharmacokinetic properties, and is well-tolerated for the treatment of PIDD.

    Our goal was to perform a scoping systematic review of the literature on the use of intravenous immunoglobulins (IVIG) for refractory status epilepticus (RSE) in adults. Articles from MEDLINE, BIOSIS, EMBASE, Global Health, Healthstar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform, clinicaltrials.gov (inception to May 2016), reference lists of relevant articles, and gray literature were searched. The strength of evidence was adjudicated using both the Oxford and GRADE methodology by two independent reviewers. Twenty-four original articles were identified. A total of 33 adult patients were described as receiving IVIG for RSE. Seizure reduction/control with IVIG occurred in 15 of the 33 patients (45.4%), with 1 (3.0%) and 14 (42.4%) displaying partial and complete responses respectively. No adverse events were recorded. Oxford level 4, GRADE D evidence exists to suggest an unclear impact of IVIG therapy in adult RSE. Routine use of IVIG in adult RSE cannot be recommended at this time.

    Pompholyx is a common eruption of small vesicles on the palms, soles, and/or lateral aspects of the fingers. It has a multifactorial etiology, including genetic determinants, allergy to metals, and id reaction; rarely it is a drug-related side effect. We report a paediatric case of pompholyx of the hands related to the intravenous immunoglobulin (IVIG) therapy for Clinically Isolated Syndrome (CIS). A 10-year-old boy, received an IVIG therapy (Venital, Kedrion Spa, Italy) at a dose of 400 mg/kg daily for five days. The fifth day of IVIG infusion, a symmetrical vesicular eruption appeared on the palms of the hands and on lateral aspects of the fingers. The lesions improved with application of topical steroids in few days. The mechanism of induction of pompholyx by IVIG therapy is unknown. A review of the Literature suggests the hypothesis that dyshidrotic eczematous reactions may be related not only to the type of IVIG, to the dose and the rates of infusion, but also to an allergic response to excipients and preservatives contained in the drug, probably elicited by an underlying neurological disease in some cases.

    Full Text Available Immunoglobulin G (IgG of excellent quality for intravenous use was obtained from the cryosupernatant of human plasma by a chromatographic method based on a mixture of ion-exchange, DEAE-Sepharose FF and arginine Sepharose 4B affinity chromatography and a final purification step by Sephacryl S-300 HR gel filtration. The yield of 10 experimental batches produced was 3.5 g IgG per liter of plasma. A solvent/detergent combination of 1% Tri (n-butyl phosphate and 1% Triton X-100 was used to inactivate lipid-coated viruses. Analysis of the final product (5% liquid IgG based on the mean for 10 batches showed 94% monomers, 5.5% dimers and 0.5% polymers and aggregates. Anticomplementary activity was 0.3 CH50/mg IgG and prekallikrein activator levels were less than 5 IU/ml. Stability at 37ºC for 30 days in the liquid state was satisfactory. IgG was stored in flasks (2.5 g/flask at 4 to 8ºC. All the characteristics of the product were consistent with the requirements of the 1997 Pharmacopée Européenne.

    Intravenous immunoglobulin (IVIg) therapy has shown promising results in treating Alzheimer’s disease (AD). In this study, a Random Forest classification model was used to identify possible effects of IVIg on a group of eight subjects who underwent immunotherapy. Cerebrospinal fluid (CSF) samples from eight AD subjects who underwent IVIg therapy were collected before the therapy, after six months of therapy, and after a three-month drug washout period. Samples were analyzed using two-dimensional gel electrophoresis and further studied using a Random Forest classification model to identify effects of IVIg on a panel of 23 putative diagnostic AD biomarkers previously identified. Six of the eight subjects showed improvements with respect to the 23 AD diagnostic biomarkers after six months of therapy compared to the samples taken at the outset of the trial. All subjects reverted back to baseline during drug washout. These results are also consistent with clinical observations. The observed improvements in subjects during six months of IVIg therapy and the reversion back to baseline during drug washout provides preliminary evidence regarding the potential use of IVIg as an AD immunotherapy.

Foi realizada uma segunda sessão de IgEV, também com melhora inicial, seguida de piora aos 65 dias de doença. Uma terceira etapa de IgEV foi realizada, sendo a melhora definitiva e sem outros episódios após 3 anos de seguimento. Os autores revisam a literatura sobre flutuações relacionadas ao tratamento. Concluem que na SGB é importante uma observação clínica rigorosa nas primeiras semanas após tratamento com IgEV e que seriam necessários estudos para elaborar protocolos alternativos de prevenção nesses casos.The authors report the case of a patient with severe Guillain-Barré syndrome (tetraplegic and on mechanical ventilation, that was treated with intravenous immunoglobulin (IVIg, 2 g/Kg. At first, there was clinical improvement, followed by clinical deterioration two weeks later. On the second course of IVIg there was, again, clinical improvement and then deterioration, 65 days after treatment. Finally, on the third course of treatment definitive recovery was achieved and no more relapses happened so far (three years after the treatment. The authors review the literature about fluctuations related to treatment with IVIg. Conclusions are that these patients should be closely observed during the first weeks after IVIg treatment, and that further studies are still necessary to elaborate alternative protocols on the prevention of these cases.

    To analyze haemolytic episodes in patients with warm antibody autoimmune haemolytic anemia (AIHA) and compare corticosteroids treatment with intravenous immunoglobulins (IVIG) (group A) or without IVIG (group B). Observational study that includes 21 haemolytic episodes occurred in 17 patients (9 males and 12 females), with a median age of 59 years (26-82). In group A, 8 episodes received IGIV + corticosteroids and in group B, 12 episodes received only corticosteroids and one rituximab. Hemoglobin (Hb) value at diagnosis was 1.8 g/dl lower (95% confidence interval: 0.6 to 3.1; P = .007) in group A, with a median Hb of 6.3g/dl in this group vs 7.9 g/dl in group B. There were non-significant differences in red blood cells transfusion (50 vs 23%; P > .20) and global increase of Hb values (7.3 vs 5.6; P > .20). Overall hematological responses were similar: 88 vs 92% (P > .20). Hematological response achieved in more severe episodes with the use of IVIG was similar to non-severe episodes treated without IVIG. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    The previous studies with Flebogamma(®) 5 % DIF intravenous immunoglobulin (IVIG) contained insufficient numbers of pediatric subjects to fully warrant a pediatric indication by the FDA. The objective of this study was to evaluate the efficacy, safety, and pharmacokinetics of Flebogamma® 5 % DIF for replacement therapy in children (age 2-16) with primary immunodeficiency diseases (PIDD). IVIG was administered at eight clinical sites to 24 subjects with well-defined PIDD at a dose of 300-800 mg/kg every 21-28 days for 12 months. The pharmacokinetics endpoint in this study was the dose-adjusted increment of the serum IgG trough levels. The calculated serious bacterial infection rate was 0.05/subject/year. The incidence of adverse events considered potentially related to IVIG during or within 72 h after completing an infusion was within the FDA guidance threshold of DIF 5 % indicating no evidence of a different pharmacokinetic profile in this pediatric population if compared to those profiles in previous Flebogamma studies in predominately adult populations. Flebogamma(®) 5 % DIF is efficacious and safe, has adequate pharmacokinetic properties, is well-tolerated, and maintains the profile of Flebogamma(®) 5 % for the treatment of children with primary humoral immunodeficiency diseases.

    A new human liquid intravenous immunoglobulin product, Flebogamma DIF, has been developed. This IgG is purified from human plasma by cold ethanol fractionation, PEG precipitation and ion exchange chromatography. The manufacturing process includes three different specific pathogen clearance (inactivation/removal) steps: pasteurization, solvent/detergent treatment and Planova nanofiltration with a pore size of 20 nm. This study evaluates the pathogen clearance capacity of seven steps in the production process for a wide range of viruses through spiking experiments: the three specific steps mentioned above and also four more production steps. Infectivity of samples was measured using a Tissue Culture Infectious Dose assay (log(10) TCID(50)) or Plaque Forming Units assay (log(10) PFU). Validation studies demonstrated that each specific step cleared more than 4 log(10) for all viruses assayed. An overall viral clearance between > or =13.33 log(10) and > or =25.21 log(10), was achieved depending on the virus and the number of steps studied for each virus. It can be concluded that Flebogamma DIF has a very high viral safety profile. 2010 The International Association for Biologicals. Published by Elsevier Ltd. All rights reserved.

    Although intravenous immunoglobulin G (IVIG) therapy has been reported in hyperbilirubinemia of Rh hemolytic disease, its use in ABO hemolytic disease has been reported in only a few studies. In our institute we have observed that almost 30% of babies with hyperbilirubinemia due to ABO hemolytic disease required exchange transfusion. To determine whether administration of IVIG to newborns with significant hyperbilirubinemia due to ABO hemolytic disease would reduce the need for exchange transfusion as a primary goal in these babies. This was a prospective study involving all newborns with significant hyperbilirubinemia due to direct Coombs-positive ABO hemolytic disease. All healthy term babies with ABO hemolytic disease with positive direct Coombs test in the period between 2000 and 2002 were identified. Significant hyperbilirubinemia was defined as hyperbilirubinemia requiring phototherapy and/or rising by 8.5 micromol/l per h (0.5 mg/dl per h) or more to require exchange transfusion. Babies were randomly assigned into two groups: group 1 (study group) received phototherapy plus IVIG (500 mg/kg); and group 2 (control group) received phototherapy alone. Exchange transfusion was carried out in any group if at any time the bilirubin level reached 340 micromol/l (20 mg/dl) or more, or rose by 8.5 micromol/l per h (0.5 mg/dl per h) in group 2. A total of 112 babies were enrolled over 2 years, 56 in each group. Exchange transfusion was carried out in four babies in the study group, while 16 babies in the control group required exchange. Late anemia was not of concern in either group. No adverse effects related to IVIG administration were recorded. Administration of IVIG to newborns with significant hyperbilirubinemia due to ABO hemolytic disease with positive direct Coomb's test reduces the need for exchange transfusion without producing immediate adverse effects.

    It has been proposed that the anti-inflammatory effects of intravenous immunoglobulin (IVIG) might be due to the small fraction of Fc-sialylated IgG. In this study we biochemically and functionally characterized sialic acid-enriched IgG obtained by Sambucus nigra agglutinin (SNA) lectin fractionation. Two main IgG fractions isolated by elution with lactose (E1) or acidified lactose (E2) were analyzed for total IgG, F(ab')(2) and Fc-specific sialic acid content, their pattern of specific antibodies and anti-inflammatory potential in a human in vitro inflammation system based on LPS- or PHA-stimulated whole blood. HPLC and LC-MS testing revealed an increase of sialylated IgG in E1 and more substantially in the E2 fraction. Significantly, the increased amount of sialic acid residues was primarily found in the Fab region whereas only a minor increase was observed in the Fc region. This indicates preferential binding of the Fab sialic acid to SNA. ELISA analyses of a representative range of pathogen and auto-antigens indicated a skewed antibody pattern of the sialylated IVIG fractions. Finally, the E2 fraction exerted a more profound anti-inflammatory effect compared to E1 or IVIG, evidenced by reduced CD54 expression on monocytes and reduced secretion of MCP-1 (CCL2); again these effects were Fab- but not Fc-dependent. Our results show that SNA fractionation of IVIG yields a minor fraction (approx. 10%) of highly sialylated IgG, wherein the sialic acid is mainly found in the Fab region. The tested anti-inflammatory activity was associated with Fab not Fc sialylation.

    Full Text Available It has been proposed that the anti-inflammatory effects of intravenous immunoglobulin (IVIG might be due to the small fraction of Fc-sialylated IgG. In this study we biochemically and functionally characterized sialic acid-enriched IgG obtained by Sambucus nigra agglutinin (SNA lectin fractionation. Two main IgG fractions isolated by elution with lactose (E1 or acidified lactose (E2 were analyzed for total IgG, F(ab'(2 and Fc-specific sialic acid content, their pattern of specific antibodies and anti-inflammatory potential in a human in vitro inflammation system based on LPS- or PHA-stimulated whole blood. HPLC and LC-MS testing revealed an increase of sialylated IgG in E1 and more substantially in the E2 fraction. Significantly, the increased amount of sialic acid residues was primarily found in the Fab region whereas only a minor increase was observed in the Fc region. This indicates preferential binding of the Fab sialic acid to SNA. ELISA analyses of a representative range of pathogen and auto-antigens indicated a skewed antibody pattern of the sialylated IVIG fractions.

    The worldwide seroprevalence of hepatitis A virus (HAV) and hepatitis B virus (HBV) has changed over the last two decades, indicating a declining incidence of HAV and HBV infections. Therefore, vaccinations against HAV and HBV are recommended for unimmunized people before traveling to an endemic area. Unfortunately, primary antibody deficiency (PAD) patients can only obtain humoral immunity through intravenous immunoglobulin G (IVIG) replacement and not from vaccination because of a defect in antibody production. However, few studies have analyzed the titers of antibodies against HAV or HBV in IVIG products. In this study, the titers of anti-HAV and anti-HBs antibodies were measured in nineteen lots of IVIG products from five manufacturers from three countries (A, B from Korea; C, D from Japan; and E from the USA), and trough titers in plasma were estimated. Concentrations of anti-HAV antibody ranged from 1,888-8,927 mIU/mL and estimated trough titers exceeded the minimal protective value in all evaluated IVIG products. Concentrations of anti-HBs antibody ranged from 438-965 mIU/mL in products A and B and were 157, 123, and 1,945 mIU/mL in products C, D, and E, respectively. Estimated trough titers in products A, B, and E exceeded the minimal protective value but those in products C and D did not reach this threshold. These data demonstrated that available IVIG products generally provide sufficient antibodies against HAV and HBV to protect patients with PAD, although the trough concentrations of anti-HBs antibody in two IVIG products did not reach the minimum protective value.

    Full Text Available Japanese encephalitis (JE virus (JEV is a mosquito-borne flavivirus found across Asia that is closely related to West Nile virus. There is no known antiviral treatment for any flavivirus. Results from in vitro studies and animal models suggest intravenous immunoglobulin (IVIG containing virus-specific neutralizing antibody may be effective in improving outcome in viral encephalitis. IVIG's anti-inflammatory properties may also be beneficial.We performed a pilot feasibility randomized double-blind placebo-controlled trial of IVIG containing anti-JEV neutralizing antibody (ImmunoRel, 400mg/kg/day for 5 days in children with suspected JE at two sites in Nepal; we also examined the effect on serum neutralizing antibody titre and cytokine profiles. 22 children were recruited, 13 of whom had confirmed JE; 11 received IVIG and 11 placebo, with no protocol violations. One child (IVIG group died during treatment and two (placebo subsequently following hospital discharge. Overall, there was no difference in outcome between treatment groups at discharge or follow up. Passive transfer of anti-JEV antibody was seen in JEV negative children. JEV positive children treated with IVIG had JEV-specific neutralizing antibody titres approximately 16 times higher than those treated with placebo (p=0.2, which was more than could be explained by passive transfer alone. IL-4 and IL-6 were higher in the IVIG group.A trial of IVIG for JE in Nepal is feasible. IVIG may augment the development of neutralizing antibodies in JEV positive patients. IVIG appears an appealing option for JE treatment that warrants further study.ClinicalTrials.gov NCT01856205.

    We conducted a double-blind, placebo-controlled study in 13 patients (aged 22 to 54 years) with relapsing-remitting multiple sclerosis (MS). They were randomly assigned to receive a loading dose of immunoglobulin IgG, 0.4 g/kg body weight/day for 5 consecutive days, followed by single booster doses of 0.4 g/kg/day, or placebo, once a month for 9 months. MRI was obtained before and during the 3rd and 6th months of treatment; examinations in the 9th and 12th months were planned. Qualitative and quantitative blinded assessments were performed. There were seven patients who received active treatment and six who received placebo. Statistical analysis was performed by the Wilcoxon test. A decrease in the size and number of lesions was observed on MRI in five patients (71 %) in the treatment group, and in two (33 %) of the placebo group at 3-month follow-up. At 6 months follow-up MRI, a decrease in the amount of lesions was observed in all patients treated with IV IgG, and in two (33 %) of the placebo group; four patients (66 %) receiving placebo showed an increase. Quantitative analysis showed a statistically significant decrease in the volume of lesions in treatment group at both 3 and 6 month follow-up. There was no statistically significant change in the placebo group. (orig.)

    Full Text Available Abstract Intravenous immunoglobulin (IVIg is a blood-derived product, used for the treatment of immunodeficiency and autoimmune diseases. Since a range of immunotherapies have recently been proposed as a therapeutic strategy for Parkinson’s disease (PD, we investigated the effects of an IVIg treatment in a neurotoxin-induced animal model of PD. Mice received four injections of MPTP (15 mg/kg at 2-hour intervals followed by a 14-day IVIg treatment, which induced key immune-related changes such as increased regulatory T-cell population and decreased CD4+/CD8+ ratio. The MPTP treatment induced significant 80% and 84% decreases of striatal dopamine concentrations (P P P

    Maternal D alloimmunization detected in early gestation requires aggressive intervention to prevent severe fetal anemia. An intrauterine transfusion (IUT) is indicated to prevent fetal death once severe fetal anemia has been detected, but is not without risk. Protocols combining therapeutic plasma exchange (TPE) and intravenous immunoglobulin (IVIG) have been described, but they usually bridge to IUT. We describe a 27-year-old G4, P0-1-2-0 Caucasian female with a history of ruptured ectopic pregnancy presented at 12 weeks' gestation with a very high anti-D titer (2048). TPE was performed on that week and twice more in the following week, with a fourth final exchange during Week 14. A loading dose of IVIG (2 g/kg) was administered over 2 days after the third TPE and then 1 g/kg per week until Week 28 (total, 14 doses). The antibody titer decreased to 256 by the beginning of 15 weeks' gestation and remained stable at that level for the remainder of the pregnancy. Doppler ultrasonographic measurements of the fetal middle cerebral artery peak flow velocity performed throughout gestation showed no evidence of fetal anemia. A healthy male infant was delivered at 37 weeks' gestation with mild immune-mediated hemolysis. The infant underwent successful treatment with an IVIG dose of 750 mg/kg and a red blood cell exchange. Our unique TPE-IVIG protocol was successful at preventing the onset of severe fetal anemia in a patient with high titer anti-D. Since IUT may be fatal, our approach offers a safer and less-invasive treatment regime that can adequately sustain a fetus until term. Published 2014.

    In the production process of a new 5% liquid intravenous immunoglobulin (IVIG-L) product (Nanogam(®) ), a combined pepsin/pH 4·4 treatment/15-nm filtration (pH 4·4/15NF) step and a solvent-detergent (SD) treatment step were incorporated to improve the virus inactivating/reducing capacity of the manufacturing process. Two prospective uncontrolled multicentre studies were performed to evaluate the safety and efficacy of this product. Efficacy, including pharmacokinetics, of IVIG-L was studied for 6 months in 18 primary immunodeficiency (PID) patients, succeeded by a long-term follow-up study (mean 2·2 years, n=17). Second, in 24 patients with idiopathic thrombocytopenic purpura (ITP), IVIG-L was studied for efficacy for 14 days. In both studies, adverse events and vital signs were recorded to study safety. In PID patients treated with IVIG-L, 0·60 and 0·38 severe infections per patient per year were reported during, respectively, the short-term and long-term follow-up. Pharmacokinetic studies resulted in an IgG half-life of 30·9 ± 11·3 days and a mean IgG trough level of 6·8 ± 1·2 g/l. In the ITP study, all patients showed an increase in platelet counts after infusion with IVIG-L, and 20/24 patients responded with a platelet count >50 × 10(9) /l (83·3%) within 1 week. IVIG-L infusions did not cause clinical relevant changes in laboratory parameters or vital signs. In clinical studies, IVIG-L (Nanogam®) demonstrated to be efficacious, well tolerated and safe. © 2011 The Author(s). Vox Sanguinis © 2011 International Society of Blood Transfusion.

    Aseptic meningitis is a rare but significant complication of intravenous immunoglobulin (IVIG) therapy. The majority of literature is limited to case reports, so the true incidence of this complication is uncertain. A retrospective review of all cases of IVIG-associated adverse transfusion reactions was performed at London Health Sciences Centre (LHSC) from January 1, 2008, to December 31, 2013. All reported transfusion reactions were evaluated to identify cases of aseptic meningitis due to IVIG. All documented IVIG infusions and lumbar punctures performed during the study period were reviewed; patients with both interventions were identified and further chart review was performed to identify aseptic meningitis. During our study period, 1324 unique patients received a total of 11,907 IVIG infusions (554,566 g) for various conditions. Eight cases of aseptic meningitis were identified, suggesting an overall incidence of 0.60% for all patients and 0.067% for all IVIG infusions. Patients presented with symptoms within 24 to 48 hours of the infusion and were treated with antibiotics initially. The reactions were self-limited, as symptoms self-resolved within 5 to 7 days. Treatment was supportive, with subsequent IVIG infusions likely requiring preinfusion medication or possibly a switch in product formulation. This review of IVIG-induced aseptic meningitis over a 6-year period identifies a more robust estimate of incidence and risk of 0.60% and 0.067% for all patients and infusions, respectively. Given that this complication can mimic infectious meningitis and cause considerable morbidity, physicians need to be aware of this rare but important condition. © 2015 AABB.

She received five pulses of IVMP (30 mg/kg/day. Two weeks after steroid weaning, she developed right hemiplegia and coma. Brain magnetic resonance imaging showed a left frontal necrotico-hemorrhagic lesion and new multifocal areas of demyelination. She underwent decompressive craniotomy and evacuation of an ongoing left frontoparietal hemorrhage. Comprehensive investigations ruled out vascular and infectious process. The neurological deterioration stopped concomitantly with combined neurosurgical drainage of the hematoma, decompressive craniotomy, IVMP, and intravenous immunoglobulins (IVIG. She developed during the following months Crohn disease and sclerosing cholangitis. After 2-year follow-up, there was no new neurological manifestation. The patient still suffered right hemiplegia and aphasia, but was able to walk. Cognitive/behavioral abilities significantly recovered. A heterozygous novel rare missense variant (c.4993A>G, p.Lys1665Glu was identified in RANBP2, a gene associated with acute necrotizing encephalopathy. RANBP2 is a protein playing an important role in the energy homeostasis of neuronal cells.ConclusionIn any ADS occurring in the context of SCD and/or autoimmune condition, we recommend to slowly wean steroids and to closely monitor the patient after weaning to quickly treat any recurrence of neurological symptom

    Schilder's disease (SD) is a rare variant of multiple sclerosis with a predilection to children. It is characterized by focal neurological abnormalities, which are atypical for MS, in conjunction with tumor-like white matter lesions on MRI. We report the case of an 11-year-old girl that demonstrates two important features of the disease: a) the clinical presentation and subsequent course in conjunction with the serial neuroradiological findings stress the feasibility of a non-invasive diagnosis of SD; and b) we report a significant clinical response to treatment with intravenous human Immunoglobulins.

    Cationization of proteins in general enhances the cellular uptake of these macromolecules, and cationized antibodies are known to retain antigen binding properties. Therefore, cationized antibodies may be therapeutic and allow for intracellular immunization. The present studies test the hypothesis that the tissue uptake of cationized immunoglobulin G (IgG) after intravenous administration may be greatly increased relative to the uptake of native proteins. The pharmacokinetics of cationized immunoglobulin G clearance from blood, and the volume of distribution of the cationized or native protein (albumin, IgG) for 10 organs was measured both in anesthetized rats and in an anesthetized adult Macaca irus cynomologous monkey. Initial studies on brain showed that serum factors inhibited uptake of 125I-cationized IgG, but not 3H-cationized IgG. The blood-brain barrier permeability surface area product for 3H-cationized IgG was 0.57 ± 0.04 microliters min-1 g-1. The ratio of the volume of distribution of the 3-H-cationized IgG compared to 3H-labeled native albumin ranged from 0.9 (testis) to 15.7 (spleen) in the rat at 3 hr after injection, and a similarly enhanced organ uptake was observed in the primate. In conclusion, these studies demonstrate that cationization of immunoglobulin greatly increases organ uptake of the plasma protein compared to native immunoglobulins, and suggest that cationization of monoclonal antibodies may represent a potential new strategy for enhancing the intracellular delivery of these proteins

    Intravenous immunoglobulin therapy and plasma exchange through transfusion of fresh frozen plasma are therapeutic options for patients with refractory pemphigus vulgaris. Passive acquisition of various clinically important antibodies through these therapies can occur, leading to false serology and negatively affecting patients' clinical care. It is recommended that dermatologists recognize the possibility of these phenomena and interpret them appropriately. Here, we report false-positive serology following intravenous immunoglobulin therapy and plasma exchange through transfusion of fresh frozen plasma in a patient with refractory pemphigus vulgaris. We also discuss the measure for misinterpretation and unnecessary clinical intervention. © 2015 Japanese Dermatological Association.

    To assess safety and efficacy of a 10% intravenous immunoglobulin in patients with primary immune thrombocytopenic purpura (ITP). ITP patients in two multicenter studies (Trials A/B) were treated with 2 g/kg Flebogamma ® 10% DIF (over 2-5 days) and were followed up to 1-3 months. 18 patients in Trial A and 58 in Trial B were enrolled (12 children in Trial B). The response rate (platelet count ≥50 × 10 9 /l) was 72.2% (Trial A) and 76.1/100% (adults/children; Trial B). Most patients improved bleedings (83.3% Trial A; 88.9% Trial B). Potential treatment-related adverse events were reported by 38.9% (Trial A) and 30.4/83.3% (adults/children; Trial B) of patients. All serious adverse events (five patients) resolved without sequelae. Flebogamma 10% DIF was effective and safe in patients with primary ITP.

    To define and characterize responders and non-responders in a group of 124 patients with post-polio syndrome who received a single treatment with intravenous immunoglobulin. Open trial, prospective follow-up study. Clinical examination and data from medical records. Short Form 36 (SF-36), Physical Activity Scale for the Elderly (PASE) and visual analogue scale (VAS) measured quality of life, physical activity and intensity of pain, respectively. Data were obtained before treatment and at 6-month follow-up. Two responder groups were identified with the outcome SF-36 Vitality and 3 with Bodily pain, respectively. Forty-five percent were positive-responders, identified before treatment by reduced physical function, muscle atrophy in the lower extremities, higher levels of fatigue and pain, and a VAS pain score above 20. Negative-responders were identified by good physical function and mental health, lesser muscle atrophy in the lower extremities, and low levels of fatigue and pain. Intravenous immunoglobulin is a biological intervention, and therefore it is important to be able to identify responders and non-responders. In order to maximize a positive outcome it is suggested that patients with a high level of fatigue and/or pain and reduced physical function are selected.

    2015-08-01

    Full Text Available In connective tissue diseases, autoantibodies cause pulmonary interstitial inflammation and fibrosis, and patients require treatment with an immunosuppressive agent such as a steroid. Dermatomyositis is an incurable, uncommon form of connective tissue disease that occasionally causes diffuse pulmonary inflammation leading to acute severe respiratory failure. In such cases, the prognosis is very poor despite treatment with high-dose steroid. In the present case, a 46-year-old man was admitted to our hospital with dyspnea. He was diagnosed with dermatomyositis combined with cryptogenic organizing pneumonia (COP with respiratory failure and underwent treatment with steroid and an immunosuppressive agent, but the COP was not improved. However, the respiratory failure did improve after treatment with intravenous immunoglobulin, which therefore can be considered a treatment option in cases where steroids and immunosuppressive agents are ineffective.

    IVIG consumption is increasing due to the fact that in many cases the drugs are being used off-label. IVIG were more likely to be used in autoimmune and systemic inflammatory diseases. However, in randomized clinical trials, a good effect was achieved only in Kawasaki disease and immune thrombocytopenic purpura. Current clinical guidelines narrowed the indications for IVIG, limiting their use in sepsis. Immunoglobulin replacement therapy is recommended for children with physiological delay of immunoglobulin production only in repeated infections, which can not be controlled or prevented with antibiotics. In secondary ID, replacement therapy must be carried out if the cause of hypogammaglobulinemia can not be eliminated or elimination is contraindicated, as well as in association with β-cell cancers, in which severe infections caused by encapsulated bacteria persist despite preventive antibiotic therapy.

    Neuralgic amyotrophy (NA) is a distinct peripheral nervous system disorder characterized by attacks of acute neuropathic pain and rapid multifocal weakness and atrophy unilaterally in the upper limb. The current hypothesis is that the episodes are caused by an immune-mediated response to the brachial plexus, however, therapeutic strategies for NA have not been well established. We retrospectively reviewed 15 case series of NA; 10 of the 15 patients received intravenous immunoglobulin (IVIg) with methylprednisolone pulse therapy (MPPT) and 9 of these 0 patients showed clinical improvement of motor impairment. Our clinical observations do not contradict the possibility that IVIg with MPPT may be one of the potential therapeutics for NA, however the efficacy remains to be established. Further confirmatory trials are needed in patients with various clinical severities and phases of NA. Further basic research and confirmatory trials should be performed to survey the efficacy of such immunomodulation therapy for NA.

    Full Text Available Abstract For patients who require replacement therapy for primary immunodeficiency, subcutaneous infusions of immunoglobulin G (IgG may be preferable to intravenous infusions for several reasons. However, at present, there is no preparation marketed for use by this route in North America. In this article, we describe the reasons patients have selected this route of therapy and the range of treatment regimens used. Approximately 20% of our patients have chosen the subcutaneous route, mainly because of adverse effects from intravenous (IV infusions or difficulties with venous access. Unit dose regimens using whole bottles of currently available 16% intramuscular preparations or sucrose-containing lyophilized preparations intended for IV use but reconstituted to 15% IgG for subcutaneous administration were individually tailored to each patient. In most cases, self-infusions or home infusions were administered once or twice a week, most commonly requiring two subcutaneous sites and 2 to 3 hours per infusion. On average, patients took 0.18 mL of IgG per kilogram of body weight per site per hour. There were no systemic adverse effects. In patients for whom comparative data were available, trough serum IgG levels were higher with subcutaneous therapy than with IV therapy.

    Full Text Available Suzanne Skoda-Smith, Troy R Torgerson, Hans D OchsSeattle Children’s Research Institute and Department of Pediatrics, University of Washington, Seattle, WashingtonAbstract: Antibody deficiency is the most frequently encountered primary immunodeficiency disease (PIDD and patients who lack the ability to make functional immunoglobulin require life-long replacement therapy to prevent serious bacterial infections. Human serum immunoglobulin manufactured from pools of donated plasma can be administered intramuscularly, intravenously or subcutaneously. With the advent of well-tolerated preparations of intravenous immunoglobulin (IVIg in the 1980s, the suboptimal painful intramuscular route of administration is no longer used. However, some patients continued to experience unacceptable adverse reactions to the intravenous preparations, and for others, vascular access remained problematic. Subcutaneously administered immunoglobulin (SCIg provided an alternative delivery method to patients experiencing difficulties with IVIg. By 2006, immunoglobulin preparations designed exclusively for subcutaneous administration became available. They are therapeutically equivalent to intravenous preparations and offer patients the additional flexibility for the self-administration of their product at home. SCIg as replacement therapy for patients with primary antibody deficiencies is a safe and efficacious method to prevent serious bacterial infections, while maximizing patient satisfaction and improving quality of life.Keywords: subcutaneous immunoglobulin, primary immunodeficiency disease, antibody deficiency, X-linked agammaglobulinemia, common variable immune deficiency

    To investigate the clinical effect and safety of anti-D immunoglobulin (anti-D) in the treatment of children with newly diagnosed acute immune thrombocytopenia (ITP) through a Meta analysis. PubMed, EMBASE, Cohrane Library, Ovid, CNKI, and Wanfang Data were searched for randomized controlled trials (RCTs) published up to April 2017. Review Manager 5.3 was used for the Meta analysis. Seven RCTs were included. The Meta analysis showed that after 72 hours and 7 days of treatment, the intravenous immunoglobulin (IVIG) group had a significantly higher percentage of children who achieved platelet count >20×10 9 /L than the anti-D group (Panti-D (50 μg/kg) group and the IVIG group (P>0.05), and there were also no significant differences in platelet count after 24 hours and 7 days of treatment between the 50 μg/kg and 75 μg/kg anti-D groups (P>0.05). The anti-D group had a significantly greater reduction in the hemoglobin level than the IVIG group after treatment, but did not need transfusion. No children in the anti-D group or the IVIG group experienced serious adverse reactions. Intravenous injection of anti-D may have a similar effect as IVIG in improving platelet count in children with acute ITP, but it may be slightly inferior to IVIG in the rate of platelet increase after treatment. The anti-D dose of 50 μg/kg may have a similar effect as 75 μg/kg. The recommended dose of anti-D for treatment of ITP is safe.

    Endotoxins have been measured routinely in the final product and during the production process to produce non-pyrogenic parenterals. Limulus-amoebocyte-lysate-reactive material was found in in-process samples and final product of one of Octapharma's intravenous immunoglobulin (IVIG) preparations. Limulus-amoebocyte-lysate (LAL) is activated by bacterial endotoxins and by (1→3)-β-D-glucans. The contribution of both compounds on the LAL-related signal was determined by three different approaches: (1) using a test specific for (1→3)-β-D-glucans, (2) by addition of β-glucan blocker, and (3) by the use of a recombinant endotoxin assay. It was shown that none of our IVIG concentrates contained elevated endotoxin contents but that the higher LAL reaction could be ascribed to (1→3)-β-D-glucans extracted from cellulose filter pads. The use of an endotoxin test kit highly sensitive for (1→3)-β-D-glucans might lead to false-positive results. (1→3)-β-D-glucans spike solutions did not evoke an increase of temperature in rabbits, suggesting that a pyrogenic reaction is not expected in patients.

When corticosteroid treatment is unsuccessful, patients may receive intravenous immunoglobulin (IVIg, rituximab, or repository corticotropin injection (RCI. This study compared real-world, non-medication MRU between patients treated with RCI and those treated with IVIg and/or rituximab for DM/PM.Methods: Claims of DM/PM patients were analyzed from the combination of three commercial health insurance databases in the United States from July 2009 to June 2014. Patients treated with RCI were propensity score matched to those treated with IVIg, rituximab, and both (IVIg+rituximab based on demographics, prior clinical characteristics, and prior MRU. Per-patient per-month (PPPM MRU and costs were compared using Poisson regression and generalized linear modeling, respectively.Results: One-hundred thirty-two RCI, 1,150 IVIg, and 562 rituximab patients had an average age of 52.6, 46.6, and 51.7 years, respectively, and roughly two-thirds were female. After matching, there were no significant differences in demographics or prior clinical characteristics.

    We conducted this prospective randomized trial of intravenous immunoglobulin (IVIG) treatment in children with newly diagnosed immune thrombocytopenic purpura (ITP) to compare the efficacy of IVIG to standard and higher doses of anti-D IVIG. Seventy-eight patients who were previously untreated and between the age of 1 and 18 years with newly diagnosed acute ITP and a platelet concentration less than 20×10/l were eligible for enrollment. In this study IVIG treatment was compared with two different doses of anti-D. Study patients were randomized to receive treatment according to one of the two single anti-D IVIG doses [50 μg/kg (n=19) or 75 μg/kg (n=20)] or 2 g/kg (400 mg/kg per day, 5 day) total dose of IVIG (n=39). There is a significant increase of 24th hour, 48th hour, 72nd hour, 7th day and 30th day platelet counts in IVIG (2 g/kg, total dose) group compared to anti-D IVIG 50 μg/kg and anti-D IVIG 75 μg/kg groups. However, there were no difference between 24th hour, 48th hour, 72nd hour, 7th day and 30th day platelet counts across anti-D IVIG 50 μg/kg and anti-D IVIG 75 μg/kg groups. In conclusion, this study suggests that IVIG is well tolerated and significantly more effective than standard and high-dose anti-D IVIG for the treatment of newly diagnosed ITP in children. Apart from this, we believe that IVIG might be the first-line treatment of these patients. Regarding this issue further prospective studies comparing different IVIG treatment regimens with anti-D IVIG treatment regimens are needed.

    Understanding the interactions between antibodies and the linear epitopes that they recognize is an important task in the study of immunological diseases. We present a novel computational method for the design of linear epitopes of specified binding affinity to Intravenous Immunoglobulin (IVIg). We show that the method, called Pythia-design can accurately design peptides with both high-binding affinity and low binding affinity to IVIg. To show this, we experimentally constructed and tested the computationally constructed designs. We further show experimentally that these designed peptides are more accurate that those produced by a recent method for the same task. Pythia-design is based on combining random walks with an ensemble of probabilistic support vector machines (SVM) classifiers, and we show that it produces a diverse set of designed peptides, an important property to develop robust sets of candidates for construction. We show that by combining Pythia-design and the method of (PloS ONE 6(8):23616, 2011), we are able to produce an even more accurate collection of designed peptides. Analysis of the experimental validation of Pythia-design peptides indicates that binding of IVIg is favored by epitopes that contain trypthophan and cysteine. Our method, Pythia-design, is able to generate a diverse set of binding and non-binding peptides, and its designs have been experimentally shown to be accurate.

    Full Text Available Intravenous immunoglobulin (IVIG is commonly used for a wide range of diagnoses, by multiple pediatric subspecialists. We report two cases of hepatitis B screening results post IVIG infusion, where positive anti-Hepatitis B core antigen serology tests indicated possible occult hepatitis infection, leading to a delay in care. However, serial antibody testing showed results consistent with the passive transfer of antibodies.

    Intravenous immunoglobulin (IVIG) is the treatment of choice in Kawasaki disease (KD). IVIG is used to prevent cardiovascular complications related to KD. However, a proportion of KD patients have persistent fever after IVIG treatment and are defined as IVIG resistant. To develop a risk scoring system based on genetic markers to predict IVIG responsiveness in KD patients, a total of 150 KD patients (126 IVIG responders and 24 IVIG nonresponders) were recruited for this study. A genome-wide association analysis was performed to compare the 2 groups and identified risk alleles for IVIG resistance. A weighted genetic risk score was calculated by the natural log of the odds ratio multiplied by the number of risk alleles. Eleven single-nucleotide polymorphisms were identified by genome-wide association study. The KD patients were categorized into 3 groups based on their calculated weighted genetic risk score. Results indicated a significant association between weighted genetic risk score (groups 3 and 4 versus group 1) and the response to IVIG (Fisher's exact P value 4.518×10 - 03 and 8.224×10 - 10 , respectively). This is the first weighted genetic risk score study based on a genome-wide association study in KD. The predictive model integrated the additive effects of all 11 single-nucleotide polymorphisms to provide a prediction of the responsiveness to IVIG. © 2017 The Authors.

    Direct comparisons of tolerability and safety of concentrated intravenous immunoglobulin (IVIG) versus less concentrated products are scarce. In this postauthorization, prospective, observational, multicenter study, a systematic comparison of 10% and 5% concentrations of Flebogamma® DIF IVIG was performed in both adult and pediatric patients treated with the studied IVIG products according to the approved indications under routine conditions. Dose of product administered, adverse events (AEs), physical assessments, laboratory tests, and concomitant therapy were analyzed. Patient recruitment in the 10% and 5% product groups was, respectively, 34 (32 analyzed, 13 of them children, receiving 130 IVIG infusions) and 35 (34 analyzed, receiving 135 IVIG infusions). Twenty-four infusions (18.5%; 95% CI: 11.8, 25.1) with the 10% product and 3 (2.2%; 95% CI: -0.3, 4.7) with the 5% product were associated with potentially treatment-related AEs (P DIF 10% and 5% concentrations, which were therefore deemed as safe and well-tolerated IVIG in the studied population. The frequency of infusions associated with treatment-related AEs was lower with the 5% concentration. © 2017 The Authors.

    Recent reports of severe haemolytic reactions upon high dose treatment with new generation intravenous immunoglobulins (IVIGs) prompted us to examine the anti-A and anti-B haemagglutinin content of these therapeutics. We compared four different test methods, namely the indirect and direct haemagglutination test as described in the European Pharmacopoiea (Ph. Eur.) and two commercial gelcard systems with the aim to define the most reliable method for a large-scale comparison of different IVIG products. Absolute titres varied when the same samples were analyzed by the four methods, while the relative ranking of six different IVIG preparations representing different manufacturing classes was identical. New generation IVIGs showed 1-2 titre steps higher anti-A titres than the older products. Haemagglutinin titres of all 48 IVIG batches analyzed were within the current Ph. Eur. specification of ≤1:64 when tested by the official pharmacopoeial method. Based on efficiency, reliability and lower costs, the direct gelcard method could be a valid alternative to the official Ph. Eur. method to serve as a limit test. However, due to the highest intermediate precision, the official Ph. Eur. method seems to be most suitable to compare haemagglutinin titres of different IVIG products.

    Prior to investing in a large, multicentre randomised controlled trial (RCT), the National Institute for Health Research in the UK called for an evaluation of the feasibility and value for money of undertaking a trial on intravenous immunoglobulin (IVIG) as an adjuvant therapy for severe sepsis/septic shock. In response to this call, this study assessed the clinical and cost-effectiveness of IVIG (using a decision model), and evaluated the value of conducting an RCT (using expected value of information (EVI) analysis). The evidence informing such assessments was obtained through a series of systematic reviews and meta-analyses. Further primary data analyses were also undertaken using the Intensive Care National Audit & Research Centre Case Mix Programme Database, and a Scottish Intensive Care Society research study. We found a large degree of statistical heterogeneity in the clinical evidence on treatment effect, and the source of such heterogeneity was unclear. The incremental cost-effectiveness ratio of IVIG is within the borderline region of estimates considered to represent value for money, but results appear highly sensitive to the choice of model used for clinical effectiveness. This was also the case with EVI estimates, with maximum payoffs from conducting a further clinical trial between £ 137 and £ 1,011 million. Our analyses suggest that there is a need for a further RCT. Results on the value of conducting such research, however, were sensitive to the clinical effectiveness model used, reflecting the high level of heterogeneity in the evidence base.

    We report a case of a 36-year old patient with prior history of thrombosis in a setting of antiphospholipid antibody syndrome (APS) as well as pregnancy-associated catastrophic antiphospholipid syndrome (CAPS), resulting in multi-organ infarction and pregnancy loss. The episode of CAPS occurred while she was receiving antepartum low-dose aspirin and therapeutic-dose enoxaparin. This patient presented again at 6 weeks gestation and ultrasounds were consistent with fetal growth restriction, concerning for placental insufficiency and thrombosis. This time, hydroxychloroquine and monthly intravenous immunoglobulin (IVIG) infusions were added to her prophylaxis regimen, resulting in a successful delivery. Platelet count and antiphospholipid antibody titers were routinely monitored throughout pregnancy as markers of disease activity for APS. Current thromboprophylaxis guidelines do not address therapeutic options to prevent further pregnancy morbidity in women who develop recurrent episodes of thrombosis or CAPS despite receiving adequate anti-thrombotic treatment. Use of hydroxychloroquine and IVIG has been associated with good outcomes in this subset of patients.

    Although there are many reports on the resistance of Kawasaki disease (KD) to initial intravenous immunoglobulin (IVIg) therapy, risk factors for coronary artery lesions in such cases remain to be established. The objective of this study was to explore when additional therapies should be administered and to identify factors helpful for selecting a therapeutic option. Based on their written clinical records, we performed a retrospective review of KD patients who did not respond to initial IVIg therapy and who therefore then underwent plasma exchange (PE) therapy. This was a case-control study to compare the presence or absence of acute coronary lesions in patients treated by PE for IVIg-unresponsive KD at Yokohama City University Hospital or at Yokohama City University Medical Center. Fifteen of 44 patients had acute coronary artery lesions (CAL) correlating with high levels of white blood cells (WBC) (P = 0.045), D-dimer (P = 0.008), and fibrin/fibrinogen degradation products (P = 0.009) and lower levels of fibrinogen (P = 0.013) prior to PE therapy. There was a strong correlation between pre-PE levels of albumin and D-dimer (Pearson's correlation coefficient of 0.610). Multivariate analyses revealed that the odds ratio for CAL when D-dimer was ≥ 4.5 μg/mL was 25.06 (95% CI, 2.56-244.91, P = 0.006). D-dimer elevation and albumin decline in IVIg-unresponsive KD patients could be risk factors for acute CAL, suggesting the possibility that angitis has spread throughout the arterial system, as far as the coronary artery. © 2014 The Authors.

    Human intravenous immunoglobulin (IGIV) has been in use for the past 20 years. This biological product is commonly provided in liquid or lyophilized dosage form. When the lyophilized product is rehydrated, it is usually administered within 2-3 h from time of complete dissolution. While this practice is advisable whenever possible, occasionally the patient or care-giver may need to delay the infusion. Hence, a study of the stability of lyophilized IGIV after reconstitution with water for injection was conducted. The reconstituted product was stored either in its original glass container or pooled into poly(vinyl chloride) (PVC) bags. The effect of extended storage on the active ingredient (IgG), excipients (glucose, albumin) and extractables [sodium from glass vials, and di-(2-ethyl-hexyl) phthalate and cyclohexanone from PVC bags] was evaluated. The stability of the active ingredient was evaluated by physico-chemical tests (molecularsize distribution, pH, appearance, total protein), monitoring titres of a specific antibody (hepatitis B surface antigen) and an antibody functional test (bacterial opsonization). To evaluate the risk of microbial contamination during reconstitution and pooling procedures, sterility, pyrogen and animal-safety tests were included in the protocol. The potential of IgG polymerizing in solution during storage and subsequent complement activation was evaluated by assaying for non-specific binding of complement (anti-complement activity). Results show that aseptically reconstituted IGIV is stable and remains sterile up to 48 h at 5 degrees C. The reconstituted product was also found to be stable at room temperature (25 degrees C) up to 12 h.

    Group B streptococcus (GBS) infection is a leading cause of sepsis and meningitis among infants, and is associated with high rates of morbidity and mortality in many countries. Protection against GBS typically involves antibody-mediated opsonization by phagocytes and complement components. The present study evaluated serotype-specific functional antibodies to GBS among Korean infants and in intravenous immunoglobulin (IVIG) products. An opsonophagocytic killing assay (OPA) was used to calculate the opsonization indices (OIs) of functional antibodies to serotypes Ia, Ib, and III in 19 IVIG products from 5 international manufacturers and among 98 Korean infants (age: 0-11 months). The GBS Ia, Ib, and III serotypes were selected because they are included in a trivalent GBS vaccine formulation that is being developed. The OI values for the IVIG products were 635-5,706 (serotype Ia), 488-1,421 (serotype Ib), and 962-3,315 (serotype III), and none of the IVIG lots exhibited undetectable OI values (Korean manufacturers. The seropositive rate among infants was significantly lower for serotype Ia (18.4%), compared to serotype Ib and serotype III (both, 38.8%). Infant age of ≥ 3 months was positively correlated with the seropositive rates for each serotype. Therefore, only a limited proportion of infants exhibited protective immunity against serotype Ia, Ib, and III GBS infections. IVIG products that exhibit high antibody titers may be a useful therapeutic or preventive measure for infants. Further studies are needed to evaluate additional serotypes and age groups. © 2017 The Korean Academy of Medical Sciences.

    Full Text Available Objective. Kawasaki disease (KD is an acute systematic vasculitis in children which causes coronary arterial lesions and hydrops of gallbladder. Our objective is to correlate the clinical significance and influence on disease outcome of patients with gallbladder abnormalities in Kawasaki dissease. Methods. Children who met KD diagnosis criteria and were admitted for IVIG treatment were retrospectively enrolled for analysis. Patients with abdominal sonography were divided into 2 groups based on the absence (Group A, N=61 or presence (Group B, N=16 of gallbladder abnormalities (GBA, defined as hydrops or acalculous cholecystitis. Between the two groups, clinical features, demographic data (including admission days, coronary artery lesions, IVIG resistance, and laboratory data before/after IVIG treatment were collected for analysis. Results. The presence of sonographic gallbladder abnormalities is correlated with higher levels of serum CRP, GPT, and neutrophils. It also points to an increased number of IVIG resistance rates in group B. There was no significant statistical difference among clinical features, age, gender, admission days, or coronary artery lesions between the two groups. Conclusion. Sonographic gallbladder abnormalities are associated with higher CRP, GPT, neutrophil and IVIG resistance in KD. It can be used as a predictor of IVIG resistance in patients with KD.

    Women with elevated natural killer (NK) cell frequency and function during pregnancy, suffer from recurrent pregnancy loss (RPL). In the present study, the possible effect of intravenous immunoglobulin (IVIG) administration on Th1 and Th2 cell frequency, cytokine secretion, and expression of transcription factors is compared between RPL patients and control group. Totally, 44 women with a history of RPL (32 women as treated group and 12 as control group) were enrolled in the study. The frequency of Th1 and Th2 lymphocytes, the expression of transcription factors related to these cells and the serum levels of associated cytokines were assessed by flowcytometry, real-time PCR and ELISA, respectively. All, assessments were performed both before and after treatment with IVIG. A significant reduction in Th1 lymphocyte frequency, transcription factor expression and cytokine levels were observed in IVIG-treated group, while all the above parameters indicated a significant increase for Th2 lymphocytes. Th1/Th2 ratio decreased significantly (p value<0.0001) at the end of treatment and 28 out of 32 (87.5%) women in IVIG-treated group had live birth in comparison with 5 out of 12 (41.6%) in untreated group. IVIG administration proves to be an efficient therapeutic strategy which is able to enhance the success rate of pregnancy through a shift in Th2 responses. Furthermore, IVIG presents efficacy for the treatment of reproduction failures especially in subjects with immune cell abnormalities and increased NK cell level and function.

    Patients with primary antibody deficiency (PAD) are being increasingly diagnosed in the developing world. However, care of these children continues to remain suboptimal due to financial and social constraints. Immunoglobulin (Ig) trough level is an important predicting factor for infections in children on replacement immunoglobulin therapy. There are no data on this aspect from the developing world. Therefore, we studied serial immunoglobulin G (IgG) trough levels in 14 children with X-linked agammaglobulinemia (XLA) receiving replacement intravenous immunoglobulin (IVIG). Infections during the course of enrolment were documented prospectively. Mean age at the time of diagnosis was 5.1 years (range 2-11 years). Mean time from onset of symptoms and initiation of therapy was 3.3 years. Two children had established chronic lung disease prior to enrolment. Total numbers of major and minor infections were 7 and 40, respectively. At a mean dose of 414 mg/kg/month of IVIG, mean trough IgG level was 435 mg/dl. Median IgG trough levels during the episodes of major and minor infections were 244 and 335 mg/dl, respectively. An escalation in IVIG dose of 100 mg/kg produced an increase in serum IgG levels by 53.6 mg/dl. Median trough IgG level of 354 mg/dl was found to be protective with 64% sensitivity and 75% specificity. A median dose of 397 mg/kg was required to keep children free of infections. Despite financial constraints and several challenges in the context of a developing country, children with XLA have good outcome on replacement immunoglobulin therapy. Furthermore, mean biological trough IgG levels are much lower than reported in for Western patients; however, studies involving larger number of subjects are required in future to draw firm conclusions.

    Chemotherapy remains a mainstay of treatment for cancer patients. However, anti-cancer drugs frequently cause a wide range of side effects, including leukopenia and gastrointestinal toxicity. These adverse effects can lead to treatment delays or necessitate temporary dose reductions. Although chemotherapy-related changes in gut morphology have been demonstrated, the influences of chemotherapeutic regimens on gut immunity are understood poorly. This study aimed to examine whether the anti-cancer drug paclitaxel (PTX) impairs gut immunity in mice. Male ICR mice were randomized into three groups: Control, low-dose PTX (low PTX; 2 mg/kg), or high-dose PTX (high PTX; 4 mg/kg). A single intravenous dose was given. On day seven after the injection, lymphocytes from Peyer patches (PP), intraepithelial (IE) spaces, and the lamina propria (LP) were counted and analyzed by flow cytometry (CD4(+), CD8(+), αβTCR(+), γδTCR(+), B220(+)). Immunoglobulin A (IgA) concentrations were measured in small intestinal and respiratory tract washings. Total, CD4(+) and γδTCR(+) lymphocyte numbers in PPs were significantly lower in the high PTX than in the control group. The CD4(+) lymphocyte numbers in the IE spaces were significantly lower in both PTX groups than in the control group. Respiratory tract IgA concentrations were lower in the high PTX than in the control group. The present data suggest high-dose PTX impairs mucosal immunity, possibly rendering patients more vulnerable to infection. Careful dose selection and new therapies may be important for maintaining mucosal immunity during PTX chemotherapy.

    There is a significant group of patients with severe asthma who require chronic use of systemic steroids for control of their disease. These patients are at risk for severe side effects from oral steroids. Intravenous immunoglobulin (IVIG) has immunomodulatory properties, and a few open-label trials have suggested its possible benefit in individuals with severe asthma. This study was designed to assess the potential benefit of IVIG as a steroid-sparing agent in patients with severe asthma. Thirty-eight immunocompetent steroid-requiring patients with severe asthma were randomly enrolled in a double-blind, placebo-controlled trial of IVIG. Of the 38 patients enrolled, 28 patients completed the study. A significant reduction in oral steroid requirement was observed in both the IVIG-treated (n = 16) and the placebo-treated (n = 12) patients. Further exploration of the results showed that IVIG, but not placebo, had a significant steroid-sparing effect in patients requiring high doses of oral steroids (ie, >2000 mg in the year before the study). Within this subgroup, IVIG treatment (n = 9) resulted in a significant decrease in oral steroid requirement, with a median of 16.4 mg/day during the pretreatment period to 3 mg/day during the treatment phase (P =. 0078). No significant decrease in oral steroid requirement was observed in placebo-treated patients (n = 8) within this subgroup. Objective and subjective parameters of the patients' asthma were unchanged in spite of the steroid tapering achieved in the group treated with IVIG. IVIG may be a useful steroid-sparing agent in patients with severe asthma requiring high doses of oral steroids.

    Background Intravenous immunoglobulin (IVIG) treatment is commonly used to treat Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) with controversial therapeutic effect. Methods We conducted a comprehensive meta-analysis through combining the published eligible studies to evaluate the effectiveness of IVIG on SJS and TEN treatment. Results A total of 26 studies were selected from public available databases. The combination of IVIG and corticosteroid markedly reduced the recovery time (by 1.63 days, 95% CI: 0.83–2.43, P < 0.001), compared with solo corticosteroid group. The favorable effects were greater in Asian (2.19, 95% CI: 1.41–2.97, P < 0.001), TEN (2.56, 95% CI: 0.35–4.77, P = 0.023) and high-dose IVIG treated individuals (1.78, 95% CI: 0.42–3.14, P = 0.010). The hospitalization length reduced by 3.19 days (95% CI: 0.08–6.30, P = 0.045), though the outcome was proven to be unstable. We found heterogeneities, which sources were probably regional factors. Besides, IVIG was inclined to decrease SJS/TEN mortality (SMR: 0.84, 95% CI: 0.66–1.08, P = 0.178). This impact was possibly more profound when patients were treated with high dose IVIG (SMR: 0.74, 95% CI: 0.50–1.08, P = 0.116), or when patients were diagnosed as TEN (SMR: 0.68, 95% CI: 0.45–1.01, P = 0.058). Conclusions Our current meta-analysis suggests that IVIG combined with corticosteroid could reduce recovery time for SJS and TEN. This effect is greater among Asian patients. Whereas, its impact on reducing mortality is not significant. PMID:27902746

    A 7-year-old Japanese boy with a 4-month history of systemic juvenile idiopathic arthritis (s-JIA) experienced disease flare with spiking fever, exanthema and arthralgia. He then developed progressive dyspnea due to severe pericarditis, and proinflammatory hypercytokinemia was suspected. Methylprednisolone pulse therapy was ineffective and echocardiography showed massive pericardial effusion had persisted. Alternatively, subsequent intravenous immunoglobulin (IVIG) therapy resulted in dramatic resolution of the pericardial effusion, and his general condition significantly improved within a few days. This case report may lend further support the use of IVIG for selected patients with s-JIA and severe pericarditis.

    We previously reported that biofilms and innate immunity contribute to the pathogenesis of Kawasaki disease. Therefore, we aimed to assess the efficacy of clarithromycin, an antibiofilm agent, in patients with Kawasaki disease. We conducted an open-label, multicenter, randomized, phase 2 trial at 8 hospitals in Japan. Eligible patients included children aged between 4 months and 5 years who were enrolled between days 4 and 8 of illness. Participants were randomly allocated to receive either intravenous immunoglobulin (IVIG) or IVIG plus clarithromycin. The primary end point was the duration of fever after the initiation of IVIG treatment. Eighty-one eligible patients were randomized. The duration of the fever did not differ between the 2 groups (mean±SD, 34.3±32.4 and 31.1±31.1 hours in the IVIG plus clarithromycin group and the IVIG group, respectively [ P =0.66]). The relapse rate of patients in the IVIG plus clarithromycin group was significantly lower than that in the IVIG group (12.5% versus 30.8%, P =0.046). No serious adverse events occurred during the study period. In a post hoc analysis, the patients in the IVIG plus clarithromycin group required significantly shorter mean lengths of hospital stays than those in the IVIG group (8.9 days versus 10.3 days, P =0.049). Although IVIG plus clarithromycin therapy failed to shorten the duration of fever, it reduced the relapse rate and shortened the duration of hospitalization in patients with Kawasaki disease.

    Pregnancies at risk of fetal and neonatal alloimmune thrombocytopenia (FNAIT) are commonly treated using weekly intravenous immunoglobulin (IVIG) at 1 g/kg maternal weight. IVIG is an expensive multidonor human blood product with dose-related side effects. Our aim was to evaluate the effectiveness of IVIG at a lower dose, i.e., 0.5 g/kg. This was a randomized controlled multicenter trial conducted in Sweden, the Netherlands and Australia. Pregnant women with human platelet antigen alloantibodies and an affected previous child without intracranial hemorrhage (ICH) were enrolled. The participants were randomized to IVIG at 0.5 or 1 g/kg per week. The analyses were per intention to treat. The primary outcome was fetal or neonatal ICH. Secondary outcomes were platelet count at birth, maternal and neonatal IgG levels, neonatal treatment and bleeding other than ICH. A total of 23 women were randomized into two groups (low dose: n = 12; standard dose: n = 11). The trial was stopped early due to poor recruitment. No ICH occurred. The median newborn platelet count was 81 × 10(9)/l (range 8-269) in the 0.5 g/kg group versus 110 × 10(9)/l (range 11-279) in the 1 g/kg group (p = 0.644). The risk of adverse outcomes in FNAIT pregnancies treated with IVIG at 0.5 g/kg is very low, similar to that using 1 g/kg, although our uncompleted trial lacked the power to conclusively prove the noninferiority of using the low dose.

    Methamphetamine dependence is a significant public health concern without any approved medications for treatment. We evaluated ibudilast, a nonselective phosphodiesterase inhibitor, to assess the safety and tolerability during intravenous methamphetamine administration. We conducted a randomized, double-blind, placebo-controlled, within-subjects crossover clinical trial. Participants received ibudilast (20 mg twice daily followed by 50 mg twice daily) and placebo, with order determined by randomization, and then underwent intravenous methamphetamine challenges (15 and 30 mg). We monitored cardiovascular effects, methamphetamine pharmacokinetics, and reported adverse events. Ibudilast treatment had similar rates of adverse events compared with placebo, and there was no significant augmentation of cardiovascular effects of methamphetamine. Pharmacokinetic analysis revealed no clinically significant change in maximum concentration or half-life of methamphetamine with ibudilast. Methamphetamine administration during ibudilast treatment was well tolerated without additive cardiovascular effects or serious adverse events, providing initial safety data to pursue ibudilast's effectiveness for the treatment of methamphetamine dependence.

    Prior clinical trials have suggested that home-based Ig treatment in multifocal motor neuropathy (MMN) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and its variant Lewis-Sumner syndrome (LSS) is safe and effective and is less costly than hospital-administered intravenous immunoglobulin (IVIg). A French prospective, dual-center, cost minimization analysis was carried out to evaluate IVIg administration (5% concentrated) at home versus in hospital with regard to costs, patients' autonomy, and patients' quality of life. The primary endpoint was the overall cost of treatment, and we adopted the perspective of the payer (French Social Health Insurance). Twenty-four patients aged 52.3 (12.2) years were analyzed: nine patients with MMN, eight with CIDP, and seven with LSS. IVIg (g/kg) dosage was 1.51 ± 0.43 in hospital and 1.52 ± 0.4 at home. Nine-month total costs per patient extrapolated to 1 year of treatment were €48,189 ± 26,105 versus €91,798 ± 51,125 in the home and hospital groups, respectively ( p  home treatment were the good tolerance and absence of side effects of IVIg administration, as well as a good understanding of the advantages and drawbacks of home treatment (75% of respondents). The mRankin scores before and after switch to home treatment were 1.61 ± 0.72 and 1.36 ± 0.76, respectively ( p  =   .027). The switch from hospital-based to home-based IVIg treatment for patients with immune neuropathy represents potentially significant savings in the management of the disease.

    Immunoglobulin replacement therapy has been standard treatment in patients with primary immunodeficiency diseases for the past 3 decades. The goal of therapy is to reduce serious bacterial infections in individuals with antibody function defects. Approximately one-third of patients receiving intravenous immunoglobulin treatment experience adverse reactions. Recent advances in manufacturing processes have resulted in products that are safer and better tolerated. Self-infusion by the subcutaneous route has become popular and resulted in better quality of life. This review summarizes the use of immunoglobulin therapy in primary immunodeficiency diseases including its properties, dosing, adverse effects, and different routes of administration.

    To demonstrate the bioequivalence between 2 intravenous immunoglobulin (IVIG) preparations, TEGELINE ® and ClairYg ® , a ready-to-use 5% IVIG, in primary immunodeficiency (PID). Secondary objectives were to assess the efficacy, safety and pharmacokinetics of ClairYg ® . Twenty-two adult PID patients receiving stable doses of TEGELINE ® (5% lyophilized IVIG) were switched to ClairYg ® for 6 months. ClairYg ® was administered under the same conditions as TEGELINE ® , either every 3 or 4 weeks. The primary endpoint was mean average total IgG trough level at steady state with ClairYg ® versus TEGELINE ® . Clinical efficacy was also assessed in terms of infections and associated events. Bioequivalence was established with a mean average total IgG trough level at steady state being 8.05g/L with TEGELINE ® and 9.17g/L with ClairYg ® (i.e. geometric mean for the difference between ClairYg ® and TEGELINE ® was 1.136; [90% CI: 1.092-1.181] P4-6g/L) throughout the study. No patient was hospitalized for infection or had serious bacterial infections while receiving ClairYg ® . The median annualized infections rate per patient was similar for both products: 4.35 [0; 21.8] for TEGELINE ® and 4.30 [0; 15.1] for ClairYg ® . Infections were less common with higher IgG trough levels (>8.16g/L). ClairYg ® showed good safety, in particular good hepatic and renal tolerance, and did not induce hemolysis. ClairYg ® pharmacokinetics profile was comparable to that of TEGELINE ® . ClairYg ® is safe and effective in the treatment of adult PID.

    To assess the therapeutic effects and safety of different doses of immunoglobulin in the treatment of Kawasaki disease. The papers related to the treatment of Kawasaki disease were electronically searched in the databases of PubMed, EMBASE, Cochrane Library, CNKI, VIP and Wanfang. Randomized clinical trials (RCT) on the treatment of Kawasaki disease with different doses of immunoglobulin were included and assessed for quality. A Mata analysis was performed by RevMan 5.0. Twenty-eight RCTs involved 2596 cases were included. The results of Meta analysis showed that there were no significant differences in the incidences of coronary artery injuries at various phases, adverse effects and fever disappearance time between the immunoglobulin treatment groups at the doses of 1 g/(kg•d) for 1-2 days and 2 g/(kg•d) for single use. The fever disappearance time in the immunoglobulin treatment group at the dose of 1 g/(kg•d) for 1-2 days was significantly shorter than that in the immunoglobulin treatment group at the dose of 400 mg/(kg•d) for 4-5 days, but there were no significant differences in the incidences of coronary artery injuries at the acute phase and 6 months after treatment and adverse effects between the two groups. The incidence of coronary artery injuries at the acute phase and 6 months was lower and the fever disappearance time was shorter in the immunoglobulin treatment group at the dose of 2 g/(kg•d) for single use than those in the immunoglobulin treatment group at the dose of 400 mg/(kg•d) for 4-5 days, but there were no significant differences in the incidences of coronary artery injuries at the subacute phase and 12 months after treatment and adverse effects between the two groups. There are similar therapeutic effects for Kawasaki disease between the immunoglobulin treatment groups at the doses of 1 g/(kg•d) for 1-2 days and 2 g/(kg•d) for single use. The fever disappearance time in the two groups is shorter than that in the treatment

    Cardiac involvement was the major leading cause of death in patients with Kawasaki and IVIG administration reduces cardiac complications. The objective of this study was to determine the frequency of cardiovascular complications and duration of fever with regard to the time of intravenous immunoglobulin (IVIG) administration of patients with Kawasaki disease. This follow-up study was done on all patients with Kawasaki disease who were hospitalized at Amirkola Children's Hospital between 2006 and 2011. Diagnosis of Kawasaki was clinical and included fever more than 5 days with 4 of 5 signs containing mucosal changes, scaling and skin rash, bilateral nonexudative conjunctivitis, cervical lymph adenopathy and edema in lower extremities. After diagnosis of Kawasaki, all patients received standard treatment (intravenous immunoglobulins and aspirin) and undergoing cardiac echocardiography in 2 weeks, 2 months and 6 months. Information including age, sex, sign of diseases, laboratory findings, and cardiac complications in echocardiography were recorded. This study was performed on 100 patients (61 boys and 39 girls) with Kawasaki disease. The mean age of children was 2.8±2.6 years. Cardiac complication rate was 47% at the onset of the disease and had reached to 7% at the end of the sixth month (P=0.000). Distribution of cardiovascular complications in the second week, the second month and the sixth month after treatment was not significantly different according to the start of time of treatment (p>0.05). Duration of fever in patients who received treatment before 10 th day (1.5±1.3) did not have significant difference (P=0.78) with patients who received after 10 th day (1.6±0.9). Result shows that most of patients (99%) responded to the treatment with IVIG and ASA and cardiovascular complication ratio decreased. There was not significant relationship between duration of fever and time of IVIG treatment initiation.

    The Di(b) antigen usually occurs with high incidence, except in certain Asian and South American Indian populations. In general, hemolysis caused by anti-Di(b) is not severe and its clinical course is benign. We report a Korean neonate with severe hemolytic disease of the newborn caused by anti-Di(b). The phenotype and genotype of the Diego blood group system of the patient and his mother were Di(a+b+) and Di(a+b-), respectively. The mother's serum and eluate from the neonate's erythrocytes contained anti-Di(b). This case was successfully managed with phototherapy and high dose iv immunoglobulin. Since most commercial antibody detection panels do not contain Di(b-) red cells, it is important to consider anti-Di(b) in cases of hemolytic disease of the newborn caused by an antibody against a high frequency antigen.

    Subcutaneous immunoglobulin (SCIG) is effective as maintenance treatment in chronic inflammatory demyelinating polyneuropathy (CIDP). We investigated whether multiple subcutaneous infusions are as effective as conventional therapy with intravenous loading doses in treatment-naive patients with CIDP. Twenty patients fulfilling the clinical and electrophysiological criteria for CIDP were included and treated with either SCIG (0.4 g/kg/week) for 5 weeks or intravenous immunoglobulin (IVIG) (0.4 g/kg/day) for 5 days. After 10 weeks, patients were switched to the opposite treatment arm and followed for a further 10 weeks. All participants were evaluated at weeks 0, 2, 5 and 10 during both therapies. Primary outcome was combined isokinetic muscle strength (cIKS). Secondary outcomes were disability, clinical evaluation of muscle strength and the performance of various function tests. All participants received both therapies, 14 completing the protocol. Overall, cIKS increased by 7.4 ± 14.5% (P = 0.0003) during SCIG and by 6.9 ± 16.8% (P = 0.002) during IVIG, the effect being similar (P = 0.80). Improvement of cIKS peaked 2 weeks after IVIG and 5 weeks after SCIG. Disability improved during SCIG treatment only. Muscle strength determined by manual muscle testing improved after 5 and 10 weeks during SCIG but only after 5 weeks during IVIG. The remaining parameters improved equally during both treatments. Plasma immunoglobulin G levels at baseline and improvement of cIKS were related. In treatment-naive patients with CIDP, short-lasting SCIG and IVIG therapy improve motor performance to a similar degree, but with earlier maximal improvement following IVIG than SCIG treatment. © 2016 EAN.

  19. Successful treatment of idiopathic pulmonary capillaritis with intravenous cyclophosphamide.

    2013-03-01

    Idiopathic pulmonary hemosiderosis (IPH), a subtype of diffuse alveolar hemorrhage is a rare condition, first described by Virchow in 1864. Historically, it manifests in children in the first decade of life with the combination of hemoptysis, iron deficiency anemia, and alveolar infiltrates on chest radiograph. More recently, diffuse alveolar hemorrhage has been classified by the absence or presence of pulmonary capillaritis (PC), the latter carrying a potential for a poorer outcome. While systemic corticosteroids remain the first line treatment option, other immune modulators have been trailed including hydroxychloroquine, azathioprine, 6-mercaptopurine, and cyclophosphamide with varying results. Our case demonstrates for the first time, the successful use of intravenous cyclophosphamide in the management of chronic idiopathic PC.

    Epitope-antibody-reactivities (EAR) of intravenous immunoglobulins (IVIGs) determined for 75,534 peptides by microarray analysis demonstrate that roughly 9% of peptides derived from 870 different human protein sequences react with antibodies present in IVIG. Computational prediction of linear B cell epitopes was conducted using machine learning with an ensemble of classifiers in combination with position weight matrix (PWM) analysis. Machine learning slightly outperformed PWM with area under the curve (AUC) of 0.884 vs. 0.849. Two different types of epitope-antibody recognition-modes (Type I EAR and Type II EAR) were found. Peptides of Type I EAR are high in tyrosine, tryptophan and phenylalanine, and low in asparagine, glutamine and glutamic acid residues, whereas for peptides of Type II EAR it is the other way around. Representative crystal structures present in the Protein Data Bank (PDB) of Type I EAR are PDB 1TZI and PDB 2DD8, while PDB 2FD6 and 2J4W are typical for Type II EAR. Type I EAR peptides share predicted propensities for being presented by MHC class I and class II complexes. The latter interaction possibly favors T cell-dependent antibody responses including IgG class switching. Peptides of Type II EAR are predicted not to be preferentially presented by MHC complexes, thus implying the involvement of T cell-independent IgG class switch mechanisms. The high extent of IgG immunoglobulin reactivity with human peptides implies that circulating IgG molecules are prone to bind to human protein/peptide structures under non-pathological, non-inflammatory conditions.

    Complementary and alternative medicine (CAM) use has grown considerably, although there is little research on the topic in Spain. The aim of this study was to determine the prevalence of complementary medicine use in adult cancer patients at the same time as they were receiving conventional treatment in a Spanish referral cancer centre. An observational, descriptive, cross-sectional study was conducted in the Ambulatory Treatment Unit during 2 consecutive weeks in March 2015. Adult patients who were receiving intravenous chemotherapy were included. Study variables were obtained from a questionnaire and medical records. 316 patients were included. 32.3% of the patients reported complementary medicine use during this period and 89% were ingesting products by mouth, herbs and natural products being the most commonly used. 81% of patients started to use complementary medicine after diagnosis, and family/friends were the main source of information. 65% of the patients reported improvements, especially in their physical and psychological well-being. Significant predictors of CAM use were female gender (P=0.028), younger age (P<0.001), and secondary education (P=0.009). A large proportion of cancer patients receiving intravenous chemotherapy also use complementary medicine, which they mainly take by mouth. Due to the risk of chemotherapy-CAM interactions, it is important for health-professionals to keep abreast of research on this issue, in order to provide advice on its potential benefit and risks.

    Human immunoglobulin preparations for intravenous or subcutaneous administration are the cornerstone of treatment in patients with primary immunodeficiency diseases affecting the humoral immune system. Intravenous preparations have a number of important uses in the treatment of other diseases in humans as well, some for which acceptable treatment alternatives do not exist. We provide an update of the evidence-based guideline on immunoglobulin therapy, last published in 2006. Given the potential risks and inherent scarcity of human immunoglobulin, careful consideration of its indications and administration is warranted.

    Objective : Open-label data suggest that intravenous immunoglobulin (IVIG) might improve lower-extremity strength in human immunodeficiency virus (HIV)-associated myelopathy (HIVM), a rare but debilitating neurologic complication of HIV. We sought to determine the feasibility of testing the efficacy of IVIG for HIVM more rigorously. Design : We conducted a randomized, double-blind, placebo-controlled feasibility trial of IVIG for HIVM, using dynamometry as an outcome measure (Clinical Trial No. NCT01561755). Setting : The study took place in an academic medical center in New York, New York Participants : Only 12 participants were enrolled in four years; critical impediments to the study were the rarity of patients with new HIVM diagnoses and prior exposure to IVIG in patients with an established diagnosis. Measurements : Dynamometry of hip flexion, knee flexion, and ankle dorsiflexion were measured; the HIV Dementia Motor Score (HDMS); and the two-minute timed walk test were utilized. Results : Recruitment was the major feasibility issue. Dynamometry was generally well-tolerated, had good test-retest reliability ( r =0.71-0.86, p Dynamometry was valid and clinically meaningful based on its correlations with the HDMS and the two-minute timed walk test. Conclusion : We conclude that an adequately powered clinical trial of IVIG for HIVM would likely require a prolonged recruitment period and multiple participating sites. Lower limb dynamometry is a useful outcome measure for HIVM, which might also be useful in other HIV-related gait disorders.

    Postdischarge treatment of complicated pneumonia includes antibiotics administered intravenously via a peripherally inserted central venous catheter (PICC) or orally. Antibiotics administered via PICC, although effective, may result in serious complications. We compared the effectiveness and treatment-related complications of postdischarge antibiotics delivered by these 2 routes. This multicenter retrospective cohort study included children ≥2 months and pneumonia between 2009 and 2012. The main exposure was the route of postdischarge antibiotic administration, classified as PICC or oral. The primary outcome was treatment failure. Secondary outcomes included PICC complications, adverse drug reactions, other related revisits, and a composite of all 4 outcomes, termed "all related revisits." Among 2123 children, 281 (13.2%) received antibiotics via PICC. Treatment failure rates were 3.2% among PICC and 2.6% among oral antibiotic recipients and were not significantly different between the groups in across-hospital-matched analysis (matched odds ratio [OR], 1.26; 95% confidence interval [CI], 0.54 to 2.94). PICC complications occurred in 7.1%. Adverse drug reactions occurred in 0.6% of children; PICC antibiotic recipients had greater odds of adverse drug reaction in across hospital matched analysis (matched OR, 19.1; 95% CI, 4.2 to 87.3). The high rate of PICC complications and differences in adverse drug reactions contributed to higher odds of the composite outcome of all related revisits among PICC antibiotic recipients (matched OR, 4.71; 95% CI, 2.97 to 7.46). Treatment failure rates between PICC and oral antibiotics did not differ. Children with complicated pneumonia should preferentially receive oral antibiotics at discharge when effective oral options are available. Copyright © 2016 by the American Academy of Pediatrics.

    Buprenorphine dependence is a relatively novel addiction. To compare the treatment outcome in three groups over 12-weeks of treatment. Two hundred and four intravenous (i.v.)-buprenorphine-dependent patients were randomised into three groups. Subjects received 50 mg oral methadone tablet, or 5 mg sublingual buprenorphine tablet, or 50 mg oral naltrexone, and a weekly 30-minute clinical counselling session. The majority (80%) had a history of opium or heroin dependency before they were introduced to i.v. buprenorphine. The main source of buprenorphine for misusers was street sale (91%). The mean duration of buprenorphine dependence was 1.9 years and the mean dose per day was 3.9 ampoules (1 ampoule contains 0.3 mg of buprenorphine in 1 ml). Overall 59% of the patients completed the 12-week study. Retention in the 50 mg methadone group was significantly better than the 5 mg dose buprenorphine group (p=0.001) and the 50 mg dose naltrexone group (p=0.000). Retention in the 5 mg buprenorphine group was significantly better than the 50 mg naltrexone dose group (p=0.000). These results support the efficacy and safety of oral methadone and sublingual buprenorphine tablets for injection buprenorphine-dependent patients.

    The pan-European survey provides useful information on the accessibility and trends of intravenous and subcutaneous immunoglobulin (IVIg/SCIg) therapy, which is used to treat primary immunodeficiency disorders (PIDs). Although immunoglobulin (Ig) therapy is the first-line treatment for PIDs, the mechanisms of action of Ig therapy may differ according to the condition it is used to treat. Moreover, intriguing presentations suggest that further investigation is required to understand more clearly both the haematological and immunoregulatory effects of therapeutic immunoglobulin. This can ultimately provide more information on optimizing Ig therapy efficacy, and establish whether individualized dosing regimens for patients will be conducive to better clinical outcomes. In addition to treating autoimmune and inflammatory conditions, there is evidence to suggest that immunoglobulins can potentially play a role in transplantation, which warrants further investigation for future use. © 2014 British Society for Immunology.

    Immune dysfunction attributed to hypogammaglobulinaemia is common in chronic lymphocytic leukaemia (CLL) and infection is a major contributor to morbidity and mortality. A higher incidence of multiple immunoglobulin and immunoglobulin G (IgG) subclass deficiency was associated with more advanced disease (P < 0·001 and P < 0·001, respectively) in a cohort of 147 CLL patients. Multiple immunoglobulin and IgG subclass deficiency were significantly associated with shorter treatment-free survival (TFS) (P < 0·001 and P = 0·006, respectively). The association between disease stage and immune dysfunction demonstrated by these data suggest aspects of immune deficiency correlate with disease severity and may be associated with shorter TFS in CLL. © 2018 John Wiley & Sons Ltd.

A vaccination program was introduced in Japan in the 1960s. Older Japanese donors could have been naturally infected with the H2N2 virus or vaccinated in the early 1960s. Human intravenous immunoglobulin (IVIG reflects the epidemiological status of the donating population in a given time period. Here, the possible viral neutralizing (VN activities of IVIG against the H2N2 virus were examined. Hemagglutination inhibition (HI and VN activities of IVIG lots manufactured from 1993 to 2010 in Japan and the United States were evaluated against H2N2 viruses. High HI and VN activities against H2N2 viruses were found in all the IVIG lots investigated. HI titers were 32–64 against the isolate in 1957 and 64–128 against the isolates in 1965. VN titers were 80–320 against the isolate in 1957 and 1280–5120 against the isolates in 1965. Both the HI and VN titers were higher against the isolate in 1965 than in 1957. Thus, antibody titers of IVIG against influenza viruses are well correlated with the history of infection and the vaccine program in Japan. Therefore, evaluation of antibody titers provides valuable information about IVIGs, which could be used for immune stimulation when a new influenza virus emerges in the human population.Keywords: IVIG, influenza, H2N2, neutralization

    (1-3)-ß-D-Glucan (BDG) is a marker for invasive fungal diseases (IFD). Administration of intravenous immunoglobulin preparations (IVIG) has been reported to lead to false positive BDG serum levels >80 pg/ml. The aim of the study was to determine the time interval between IVIG infusion and normalisation of BDG serum levels. In 22 paediatric haemato-/oncologic patients, we analysed 92 BDG serum levels obtained within 4 weeks after IVIG administration (0.5 to 1 g/kg body weight), correlated them to 54 IVIG episodes and compared them to 76 BDG levels obtained in 29 patients without IVIG administration in the 4 weeks prior to BDG analyses (control group). BDG peak levels within 3 days after IVIG ranged from 21.47 to 660.38 (median 201.4) pg/ml. BDG serum levels at 7, 14 and 21 days (+/-1 day each) after IVIG infusion were significantly higher than BDG serum levels in the control group (p < 0.001 each). By days 7, 14, and 21 (+/-1 day each) after IVIG infusion, BDG serum levels have normalized (<80 pg/ml) in 64.0%, 76.5% and 100%, respectively. IVIG administration leads to false positive BDG levels in the vast majority of patients. Elevated BDG levels may be detectable for more than two weeks after IVIG administration, while BDG levels normalized within 3 weeks in all patients. Therefore, BDG should not be used to diagnose IFD within three weeks after IVIG administration. Copyright © 2017 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

    Intravenous immunoglobulin replacement therapy represents the standard treatment for hypogammaglobulinemia secondary to B-cell lymphoproliferative disorders. Subcutaneous immunoglobulin infusion is an effective, safe and well-tolerated treatment approach in primary immunodeficiencies but no extensive data are available on their use in secondary hypogammaglobulinemia, a frequent phenomenon occurring after treatment with anti-CD20 monoclonal antibodies in lymphoproliferative disorders. In this retrospective study we evaluated efficacy (serum IgG trough levels, incidence of infections per year, need for antibiotics) and safety (number of adverse events) of intravenous (300 mg/kg/4 weeks) versus subcutaneous (75 mg/kg/week) immunoglobulin replacement therapy in 61 patients. In addition, the impact of the infusion methods on quality of life was compared. All patients were treated with subcutaneous immunoglobulin, and 33 out of them had been previously treated with intravenous immunoglobulin. Both treatments appeared to be effective in replacing Ig production deficiency and in reducing the incidence of infectious events and the need for antibiotics. Subcutaneous immunoglobulin obtained a superior benefit when compared to intravenous immunoglobulin achieving higher IgG trough levels, lower incidence of overall infection and need for antibiotics. The incidence of serious bacterial infections was similar with both infusion ways. As expected, a lower number of adverse events was registered with subcutaneous immunoglobulin, compared to intravenous immunoglobulin, with no serious adverse events. Finally, we observed an improvement in health-related quality of life parameters after the switch to subcutaneous immunoglobulin. Our results suggest that subcutaneous immunoglobulin is safe and effective in patients with hypogammaglobulinemia associated to lymphoproliferative disorders. Copyright© Ferrata Storti Foundation.

    Evidence concerning the effectiveness of anti-cytomegalovirus immunoglobulin (CMVIg) following lung transplantation in the era of new antiviral agents is limited and controversial. At-risk patients (donor seropositive/recipient seronegative [D+/R-] and R+) received valganciclovir for 3 months (R+) or 6 months (D+/R). CMVIg (2 mg/kg) was given to D+/R- patients on days 1, 4, 8, 15, and 30 post-transplant, then monthly for a further year. Patients with valganciclovir-induced leukopenia were switched to CMVIg (2 mg/kg) prophylaxis. Tissue-invasive disease was treated with intravenous ganciclovir with CMVIg (2 mg/kg) every other day for 1 week and then weekly until discharge. Of 159 patients analyzed, 26 (17%) were D+/R-. Cytomegalovirus (CMV) viremia was more frequent in D+/R- recipients than in R+ patients (61% vs. 35%; P38°C), leukopenia, and detection of CMV in blood. Ten patients developed tissue-invasive disease after completion of prophylaxis (5 pneumonitis and 5 gastrointestinal disease); all were successfully treated with combined intravenous ganciclovir and CMVIg. None of the 18 donor seropositive/recipient seronegative patients who were switched from valganciclovir to CMVIg for persistent leukopenia developed CMV viremia during treatment. No cases of CMV infection or disease were attributable to ganciclovir-resistant strains. During follow-up, 44 patients died (4/26 R+/D- [15%], 40/133 R+ [30%), none directly due to CMV infection. Combined prophylaxis with valganciclovir and CMVIg delayed CMV viremia and tissue-invasive disease in D+/R- lung transplant recipients, and prevented CMV-related mortality and development of ganciclovir resistance. CMVIg monotherapy prophylaxis was effective in R+ patients with ganciclovir-related toxicity.

    The purpose of this study was to determine differences in 131 I biokinetics after oral or intravenous treatment of hyperthyroidism (0,81 GBq) or differentiated thyroid cancer (1,85 GBq) following thyroidectomy. 20 patients with differentiated carcinoma and 20 patients with hyperthyroidism were studied. In each group 10 patients were treated perorally and 10 patients intravenously. The integrated whole-body activities during therapy were significantly lower, by an average 23% (cancer) and 45% (hyperthyroidism) than after oral application. It is most likely that these differences between oral and intravenous application are due to the higher serum activity after intravenous therapy. It is concluded that a higher activity dose of 131 I must be given orally to achieve the same target dose as after intravenous application. (orig.) [de

    Evidence indicates that corticosteroid therapy might be beneficial for the primary treatment of severe Kawasaki disease. We assessed whether addition of prednisolone to intravenous immunoglobulin with aspirin would reduce the incidence of coronary artery abnormalities in patients with severe Kawasaki disease. We did a multicentre, prospective, randomised, open-label, blinded-endpoints trial at 74 hospitals in Japan between Sept 29, 2008, and Dec 2, 2010. Patients with severe Kawasaki disease were randomly assigned by a minimisation method to receive either intravenous immunoglobulin (2 g/kg for 24 h and aspirin 30 mg/kg per day) or intravenous immunoglobulin plus prednisolone (the same intravenous immunoglobulin regimen as the intravenous immunoglobulin group plus prednisolone 2 mg/kg per day given over 15 days after concentrations of C-reactive protein normalised). Patients and treating physicians were unmasked to group allocation. The primary endpoint was incidence of coronary artery abnormalities during the study period. Analysis was by intention to treat. This trial is registered with the University Hospital Medical Information Network clinical trials registry, number UMIN000000940. We randomly assigned 125 patients to the intravenous immunoglobulin plus prednisolone group and 123 to the intravenous immunoglobulin group. Incidence of coronary artery abnormalities was significantly lower in the intravenous immunoglobulin plus prednisolone group than in the intravenous immunoglobulin group during the study period (four patients [3%] vs 28 patients [23%]; risk difference 0·20, 95% CI 0·12-0·28, pKawasaki disease in Japan.

    Intravenous and intramuscular antiseizure drugs (ASDs) are essential in the treatment of clinical seizure emergencies as well as in replacement therapy when oral administration is not possible. The parenteral formulations provide rapid delivery and complete (intravenous) or nearly complete (intramuscular) bioavailability. Controlled administration of the ASD is feasible with intravenous but not intramuscular formulations. This article reviews the literature and discusses the chemistry, pharmacology, pharmacokinetics, and clinical use of currently available intravenous and intramuscular ASD formulations as well as the development of new formulations and agents. Intravenous or intramuscular formulations of lorazepam, diazepam, midazolam, and clonazepam are typically used as the initial treatment agents in seizure emergencies. Recent studies also support the use of intramuscular midazolam as easier than the intravenous delivery of lorazepam in the pre-hospital setting. However, benzodiazepines may be associated with hypotension and respiratory depression. Although loading with intravenous phenytoin was an early approach to treatment, it is associated with cardiac arrhythmias, hypotension, and tissue injury at the injection site. This has made it less favored than fosphenytoin, a water-soluble, phosphorylated phenytoin molecule. Other drugs being used for acute seizure emergencies are intravenous formulations of valproic acid, levetiracetam, and lacosamide. However, the comparative effectiveness of these for status epilepticus (SE) has not been evaluated adequately. Consequently, guidelines for the medical management of SE continue to recommend lorazepam followed by fosphenytoin, or phenytoin if fosphenytoin is not available. Intravenous solutions for carbamazepine, lamotrigine, and topiramate have been developed but remain investigational. The current ASDs were not developed for use in emergency situations, but were adapted from ASDs approved for chronic oral use. New

    Rotavirus infection is the most common neonatal nosocomial viral infection. It is a major health problem worldwide. Epidemics with the newer P(6)G9 strains have been reported in neonatal units globally. These strains can cause severe symptoms in most infected infants. Infection control measures become necessary and the utilization of hospital resources increase. Local mucosal immunity in the intestine to rotavirus is important in the resolution of infection and protection against subsequent infections. Boosting local immunity by oral administration of anti-rotaviral immunoglobulin preparations might be a useful strategy in treating rotaviral infections, especially in low birth weight babies. To determine the effectiveness and safety of oral immunoglobulin preparations for the treatment of rotavirus diarrhea in hospitalized low birth weight infants (birth weight less than 2500 g) Electronic databases including The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2004), MEDLINE, EMBASE and CINAHL, Biological Abstracts (BIOSIS) were searched by the strategy outlined in the protocol. Science Citation Index search for all articles that referenced Barnes 1982 were searched. The proceedings of the Pediatric Academic Societies published online at 'Abstracts Online' were searched. Ongoing registered trials at www.clinicaltrials.gov and www.controlled-trials.com were searched. Authors prominent in the field were contacted for any unpublished articles and more information on published articles was sought. Reference lists of identified clinical trials and personal files were also reviewed. The above search was updated in July 2011. The criteria used to select studies for inclusion were: 1) DESIGN: randomized or quasi-randomized controlled trials 2) Hospitalized low birth weight infants with rotavirus diarrhea 3) INTERVENTION: Oral immunoglobulin preparations compared to placebo or no intervention 4) At least one of the following outcomes

    Novel immune globulin (IG) products (RI-002, RI-001) have been designed to provide protection against respiratory syncytial virus (RSV) mediated respiratory illness while at the same time meeting the manufacturing requirements established by FDA for antibody supplementation in immunocompromised subjects. Areas covered: This review covers the manufacture and development of both RI-001 and RI-002, including the selection of plasma donors for IG preparation with high-titers of anti-RSV antibody, in vitro, and preclinical data in the cotton rat model S. hispidus, and clinical trials including Phase II and compassionate use studies of RI-001 and a multi-center, pivotal Phase III study of RI-002 in PIDD patients. Expert commentary: The data demonstrate that RI-002 is efficacious in the prevention and treatment of RSV in preclinical normal and immune suppressed animal models and is safe and efficacious in the treatment of patients with various forms of primary immunodeficiency disease (PIDD). This product offers potential advantages over other available IG's for prophylaxis in immunocompromised patients requiring polyclonal immunoglobulin supplementation because of its unique antibody composition. In addition to its enhanced neutralizing anti-RSV activity and its polyclonal IG composition, there is preclinical data to support the use of RI-002 for humoral protection against other respiratory pathogens.

    Incarcerated intravenous heroin users have more problematic patterns of heroin use, but are less likely to access methadone maintenance treatment by their own initiative than heroin users in the community. The present study examined predictors for receiving methadone maintenance treatment post-release among incarcerated intravenous heroin users within a 24-month period. This cohort study recruited 315 incarcerated intravenous heroin users detained in 4 prisons in southern Taiwan and followed up within the 24-month period post-release. Cox proportional hazards regression analysis was applied to determine the predictive effects of sociodemographic and drug-use characteristics, attitude toward methadone maintenance treatment, human immunodeficiency virus serostatus, perceived family support, and depression for access to methadone maintenance treatment after release. There were 295 (93.7%) incarcerated intravenous heroin users released that entered the follow-up phase of the study. During the 24-month follow-up period, 50.8% of them received methadone maintenance treatment. After controlling for the effects of the detainment period before and after recruitment by Cox proportional hazards regression analysis, incarcerated intravenous heroin users who had positive human immunodeficiency virus serostatus (HR = 2.85, 95% CI = 1.80-4.52, p maintenance treatment before committal (HR = 1.94, 95% CI = 1.23-3.05, p maintenance treatment within the 24-month follow-up period. Positive human immunodeficiency virus serostatus with fully subsidized treatment and previous methadone maintenance treatment experiences predicted access of methadone maintenance treatment post-release. Strategies for getting familiar with methadone maintenance treatment during detainment, including providing methadone maintenance treatment prior to release and lowering the economic burden of receiving treatment, may facilitate entry of methadone maintenance treatment for incarcerated intravenous heroin

    Once-daily intravenous cefazolin with probenecid is used commonly to treat cellulitis. The primary objective of this study was to determine the risk factors of treatment failure with this regimen. This was a retrospective cohort study of adult outpatients with cellulitis who were initially treated with once-daily intravenous cefazolin plus probenecid. Treatment failure is defined as inadequate improvement that necessitates either hospital admission or a change in antibiotic therapy to a different intravenous regimen. A stepwise logistic regression analysis was performed to determine the risk factors for regimen failure. From January 2003 to December 2008, 159 patients with cellulitis were initially treated with once daily intravenous cefazolin plus probenecid. Thirty-five (22%) patients had treatment failure. The treatment for 53% (9/17) of the patients with a history of chronic venous disease (CVD) failed, whereas the treatment for 18% (26/142) of patients without CVD failed (P = 0.001). Multivariate analysis identified the presence of CVD as the only risk factor associated with treatment failure (odds ratio 4.4, 95% confidence interval 1.5-13; P = .007). Patients with cellulitis and CVD who are being treated with once-daily intravenous cefazolin plus probenecid should be monitored closely for treatment failure.

    Approximately two-thirds of patients with chronic inflammatory demyelinating polyneuropathy (CIDP) need long-term intravenous immunoglobulin. Subcutaneous immunoglobulin (SCIg) is an alternative option for immunoglobulin delivery, but has not previously been investigated in a large trial of CIDP. The PATH study compared relapse rates in patients given SCIg versus placebo. Between March 12, 2012, and Sept 20, 2016, we studied patients from 69 neuromuscular centres in North America, Europe, Israel, Australia, and Japan. Adults with definite or probable CIDP who responded to intravenous immunoglobulin treatment were eligible. We randomly allocated participants to 0·2 g/kg or 0·4 g/kg of a 20% SCIg solution (IgPro20) weekly versus placebo (2% human albumin solution) for maintenance treatment for 24 weeks. We did randomisation in a 1:1:1 ratio with an interactive voice and web response system with a block size of six, stratified by region (Japan or non-Japan). The primary outcome was the proportion of patients with a CIDP relapse or who were withdrawn for any other reason during 24 weeks of treatment. Patients, caregivers, and study personnel, including those assessing outcomes, were masked to treatment assignment. Analyses were done in the intention-to-treat and per-protocol sets. This trial is registered with ClinicalTrials.gov, number NCT01545076. In this randomised, double-blind, placebo-controlled trial, we randomly allocated 172 patients: 57 (33%) to the placebo group, 57 (33%) to the low-dose group, and 58 (34%) to the high-dose group. In the intention-to-treat set, 36 (63% [95% CI 50-74]) patients on placebo, 22 (39% [27-52]) on low-dose SCIg, and 19 (33% [22-46]) on high-dose SCIg had a relapse or were withdrawn from the study for other reasons (p=0·0007). Absolute risk reductions were 25% (95% CI 6-41) for low-dose versus placebo (p=0·007), 30% (12-46) for high-dose versus placebo (p=0·001), and 6% (-11 to 23) for high-dose versus low-dose (p=0·32

    The role of specific immunoglobulins at mucosal sites in imparting protection against disease, such as rotavirus-associated diarrhoea, is well-established. Oral immunoglobulin therapy with egg yolk-derived antirotavirus immunoglobulins has previously been shown to achieve moderate therapeutic effect in diarrhoea due to rotavirus in a clinical trial. Here, data on the therapeutic potential of the same immunoglobulin preparation in an infant mouse model of rotavirus-induced diarrhoea is presented. The use of an animal model has allowed therapy to be evaluated with higher doses of immunoglobulins and has suggested that an improved therapeutic effect can be achieved by increasing the dose in the clinical setting.

  15. Intravenous ferric carboxymaltose for the treatment of iron deficiency anemia

    Directory of Open Access Journals (Sweden)

    João Ricardo Friedrisch

    2015-12-01

    Full Text Available ABSTRACT Nutritional iron deficiency anemia is the most common deficiency disorder, affecting more than two billion people worldwide. Oral iron supplementation is usually the first choice for the treatment of iron deficiency anemia, but in many conditions, oral iron is less than ideal mainly because of gastrointestinal adverse events and the long course needed to treat the disease and replenish body iron stores. Intravenous iron compounds consist of an iron oxyhydroxide core, which is surrounded by a carbohydrate shell made of polymers such as dextran, sucrose or gluconate. The first iron product for intravenous use was the high molecular weight iron dextran. However, dextran-containing intravenous iron preparations are associated with an elevated risk of anaphylactic reactions, which made physicians reluctant to use intravenous iron for the treatment of iron deficiency anemia over many years. Intravenous ferric carboxymaltose is a stable complex with the advantage of being non- dextran-containing and a very low immunogenic potential and therefore not predisposed to anaphylactic reactions. Its properties permit the administration of large doses (15 mg/kg; maximum of 1000 mg/infusion in a single and rapid session (15-minute infusion without the requirement of a test dose. The purpose of this review is to discuss some pertinent issues in relation to the history, pharmacology, administration, efficacy, and safety profile of ferric carboxymaltose in the treatment of patients with iron deficiency anemia.

    The aim of this study was to evaluate the outcome of pretreatment of Acanthamoeba keratitis with intravenous pentamidine (IVP) before therapeutic keratoplasty (TKP). A retrospective chart review was performed of the medical records of every patient treated with IVP before TKP for Acanthamoeba keratitis at a single, tertiary care eye center between January 1, 2002, and December 31, 2012. The main outcome measures were microbiological cure, graft survival, and visual outcome. Eight eyes of 7 patients met the inclusion criteria. Preoperatively, all 8 eyes had failed traditional antiamoebic therapy, including 5 eyes with recurrent infections after previous TKP. The patients were treated with IVP (190-400 mg/d) for a median of 14 days (range, 7-26 days). After 8 TKP, a microbiological cure was achieved, and a clear graft was maintained in 5 (62.5%) eyes during a mean follow-up interval of 31.2 months (range, 1.0-95.7 months). Repeat TKP in 3 eyes with recurrent Acanthamoeba keratitis resulted in 2 additional microbiological cures and 1 more clear graft. The final best-corrected visual acuity was ≥20/40 in 5 (62.5%) eyes and worse than 20/200 in 3 eyes. Overall, the final vision was improved in 6 (75.0%) eyes, remained the same in 1 (12.5%) eye, and was worse in 1 (12.5%) eye. The adjunctive use of IVP before TKP may assist with the achievement of microbiological cure, clear graft, and good visual outcome in a majority of eyes with Acanthamoeba keratitis.

DOI: 10.1002/14651858.CD006921.pub2).Multiple sclerosis (MS), a chronic inflammatory and neurodegenerative disease of the central nervous system (CNS), is characterized by recurrent relapses of CNS inflammation ranging from mild to severely disabling.  Relapses have long been treated with steroids to reduce inflammation and hasten recovery.  However, the commonly used intravenous methylprednisolone (IVMP) requires repeated infusions with the added costs of homecare or hospitalization, and may interfere with daily responsibilities. Oral steroids have been used in place of intravenous steroids, with lower direct and indirect costs. The primary objective was to compare efficacy of oral versus intravenous steroids in promoting disability recovery in MS relapses Multiple Sclerosis and Rare Diseases of the Central Nervous System Group's Trials Register (January 2012), abstracts from meetings of the American Academy of Neurology (2008-2012), the European Federation of Neurological Sciences (2008-2012), the European Committee for Treatment and Research in Multiple Sclerosis and American Committee for Treatment and Research in Multiple Sclerosis (2008-2012) handsearching.

Whereas the second consists of twenty male patients suffering from squamous cell carcinoma affecting the head and neck region without direct involvement of the major salivary glands. patients of this group received radiotherapy as the sole line of treatment where the field of gamma irradiation involved the major salivary glands. The results revealed higher rate of salivary flow and salivary IgA in the cancer patients group as compared with the control group. A progressive decrease of both salivary flow rate and IgA was observed with increasing doses of gamma irradiation. 4 figs., 2 tabs

    This is a report of the clinical characteristics and therapeutic response to treatment of 51 patients with hepatic amebic abscess, studied at a general hospital in a two year period. In this group of patients without complications, the 100% cure was achieved in 5.5 days with metronidazole I.V.; the next effective regimen was metronidazole. I.V. plus emetine I.M., that gave a 100% cure in 7.4 days, so it became obvious that other kind of treatment or the addition of antibiotics are of no benefit and are potentially dangerous. The response to the different therapeutic regimens in this study, agree with what is known about the effectiveness of metronidazole used either by the oral or I.V. route in hepatic amebic abscess.

    Multiple sclerosis (MS) is a chronic, neurological, immune-mediated disease that can worsen in the postpartum period. There is no consensus on the use of immunoglobulin for prevention of disease relapses after delivery. We have shown that the controversial beneficial effect of immunoglobulin given immediately after birth could not be observed in patients with MS.

It was shown that the isolated Immunoglobulin fraction bound enterotoxigenic Escherichia coli (ETEC) and Salmonella ssp. and inhibited...... their adhesion to porcine epithelial cells in vitro. As the immunoglobulin fraction is intended for oral use as a feed supplement, we also tested the safety of feeding 4 grams of natural immunoglobulins to 4-5 week old weaner piglets for 14 days and observed no adverse effects. In an experimental model of E....... coli F4+ induced PWD, we observed that piglets given IgG as a feed supplement cleared the E coli infection significantly faster than control weaner piglets not receiving an immunoglobulin feed supplement. Furthermore, deep sequencing of the ileal microbiota showed a significantly lowered colonization...

Single-center, retrospective review. Cardiovascular hospital within a university-affiliated teaching institution. Eighty-two patients hospitalized for heart failure between September 1, 2009, and August 31, 2011, who were receiving background intravenous furosemide therapy (total daily dose ≥ 160 mg); of those patients, 28 patients also received oral hydrochlorothiazide (median dose 25 mg [interquartile range 25-50 mg]), and 54 patients also received intravenous chlorothiazide (median dose 500 mg [interquartile range 250-750 mg]). The primary outcome was change in 24-hour urine output. Urine output was recorded from the 24 hours before and after the first administration of either oral hydrochlorothiazide or intravenous chlorothiazide. Baseline characteristics, with the exception of female sex (p=0.01) and home loop diuretic dose (p=0.03), were similar between groups. Twenty-four-hour urine output before administration of the thiazide diuretic was not significantly different between groups. After treatment, 24-hour urine output increased in both groups; however, urine output increased to a lesser extent with oral hydrochlorothiazide (from mean ± SD 2104 ± 830 ml to 3038 ± 917 ml) than with intravenous chlorothiazide (from 2342 ± 978 ml to 4128 ± 1755 ml) (p=0.005). Hypokalemia occurred frequently in both groups: 71.4% and 83.3% in the oral hydrochlorothiazide and intravenous chlorothiazide groups, respectively (p=0.21). Among hospitalized patients with heart failure receiving intravenous loop diuretics, the addition of either oral hydrochlorothiazide or intravenous chlorothiazide augmented diuresis. Urine output increased to a greater extent with intravenous chlorothiazide compared with oral hydrochlorothiazide. However

    To evaluate the efficacy and limitation of intra-arterial urokinase (IAUK) infusion for treatment of acute cerebral stroke. Twenty-seven acute cerebral stroke patients treated with IAUK infusion within six hours of stroke onset were reviewed. All patients showed normal initial brain findings on CT. In 21 patients, urokinase(5-15 x 10 5 IU) was administered through a microcatheter placed into or proximal to occluded segment. Mechanical disruption of thrombus by guidewire was performed in 17 patients. Angiographic and clinical responses and complications after IAUK infusion, were evaluated and the results were compared with those of intravenous heparin(N=19) and urokinase infusion(N=19). Complete or partial angiographic recanalization of occluded segment was found in 18 patients (67%), and neurologic improvement was followed in 14 patients(52%). The degree of improvement on the stroke scale score after IAUK infusion was statistically more significant(p<0.05) than that shown after intravenous heparin and urokinase infusion. Complications after IAUK infusion were large(15%) and small amount intracerebral hemorrhage(15%), contrast leakage into brain parenchyma(11%), and gastrointestinal bleeding(4%). Between the IAVK and the intravenous urokinase infusion group, differences in extent and types of complications were statistically insignificant, but were significantly higher in those two groups than in the intravenous heparin infusion group. IAUK infusion may be effective for the treatment of acute cerebral stroke

    under conventional heart failure treatment cannot be ruled out completely as the main cause for amelioration. ESETCID (European Study on the Epidemiology and Treatment of Cardiac Inflammatory Disease) is a double-blind, randomized, placebo-controled three-armed trial with prednisolone and azathioprine for autoreactive (virus negative) DCMi, interferon alpha for enterovirus positive DCMi, high-dose immunoglobulin for cytomegalovirus and intermediate dose for adeno- and Parvo B19 DCMi. It has now randomized more than 120 patients to the different treatment arms. Its final result has still to be awaited.-Patients not willing to randomize in the trial were included in a registry follow-up, which shows improvement of hemodynamic parameters and elimination of the inflammation in the majority of patients. This is in concordance with several non-randomized trials. Since evidence is conflicting (level of evidence C, indication class IIb; if negative viral etiology is taken into consideration class IIa) treatment with immunosuppression cannot be generally recommended but should be further evaluated in doubleblind randomized clinical trials or at least in controlled trials and registries. This also applies to treatment with interferon for enteroviral or other viral infections in the heart. : The elimination of anticardiac antibodies, which have been associated with DCMi, is a currently discussed concept, which is supported by published registry data and a few very small controlled investigations but not by a randomized double-blind trial with clinical endpoints of relevance. In some studies immunoglobulins have been substituted, so that an additional immunomodulatory effect has to be taken into account. The current proof of concept can be ranked level of evidence C, indication class IIa only. An even more challenging and still more attractive hypothesis is that cardiac inflammation caused by specific circulating beta-adrenoceptor antibodies can be eradicated with the elimination

    Both intravenous and subcutaneous immunoglobulins are therapeutic modalities approved in various conditions, including primary and secondary immune deficiencies and autoimmune disorders. To date, immunoglobulins have more often been considered as a safe medication, with minor adverse effects such as hypertension, fever and chills, nausea, myalgia or headache. However, with the wider use of immunoglobulins in the treatment of autoimmune diseases, severe side effects have also been reported to occur in immunoglobulin-treated patients, especially anaphylaxis, aseptic meningitis, acute renal impairment, thrombotic events as well as haematological manifestations. This paper reviews all the potential adverse events related to immunoglobulin therapy and establishes a comprehensive guideline for the management of these events.

  14. Omalizumab: an anti-immunoglobulin E antibody for the treatment of allergic respiratory diseases

    Directory of Open Access Journals (Sweden)

    J. Bousquet

    2008-04-01

    Full Text Available Immunoglobulin E (IgE is central to the development of allergic diseases. Cross-linking of cell-bound IgE by the allergen leads to the initiation of the inflammatory cascade. Omalizumab, an anti-IgE antibody, forms complexes with free IgE, thereby inhibiting the allergic reaction before its commencement. A survey of the clinical trials performed on omalizumab indicated that this anti-IgE antibody is efficacious and well tolerated in the treatment of separate and concomitant asthma and rhinitis. In patients with poorly controlled asthma, omalizumab reduced the asthma exacerbation and emergency visit rate, along with improving the quality of life. The improvement in asthma control was associated with a reduction of inhaled and oral corticosteroids. Improved nasal symptom scores and a reduced need for antihistamines were observed in patients with allergic rhinitis. Omalizumab was also proven to be effective as an add-on therapy for concomitant asthma and rhinitis. In conclusion, omalizumab provides an integrated approach for the treatment and management of allergic respiratory diseases.

    The results for 18 consecutive patients with severe thyroid-associated ophthalmopathy (TAO) treated with high-dose, pulsed intravenous methylprednisolone (MP) are presented in this paper. Eighteen (18) patients with severe TAO, defined as either optic neuropathy, progressive diplopia, or severe soft-tissue swelling accompanied by evidence of NOSPECS class 2b or more severe eye disease, were studied in a prospective, noncontrolled case series. Patients were treated with 1.5 g of intravenous MP, divided over 3 days, followed by a tapering course of oral prednisolone. All patients were examined before treatment, 1 week and 1 month after commencement of treatment and at 2-3 monthly intervals thereafter. Assessment of visual acuity, differential intraocular pressure (IOP), soft-tissue inflammation, diplopia, and exophthalmometry were used to calculate a modified ophthalmopathy index (OI) for each patient at each visit. Median duration of follow-up was 14 months. A statistically significant reduction in OI following treatment with high-dose MP was observed after 1 week of treatment from 10.8 +/- 3.9 standard deviation (SD) to 8.3 +/- 3.4 (SD) (P < 0.001) and between 1 week and the end of the treatment period (OI, 7.2 +/- 3.4 (SD); P < 0.05). A response occurred in 83% of patients within a week but only 66% maintained this response. There was a significant negative correlation between response to treatment (OI before treatment-OI after treatment) and duration of eye disease (P = 0.034, Spearman correlation). High-dose, pulsed intravenous MP is an effective medical treatment for severe TAO. Responders can be identified within the 1st week. Treatment response is inversely related to disease duration.

    Peptic ulcer bleeding is a common medical emergency associated with significant mortality and healthcare costs. All recent guidelines agree on the beneficial role of proton pump inhibitor treatment, but there is still controversy regarding the optimal dose and route of administration of proton pump inhibitors. The evaluated article reports on a large, single-center randomized controlled trial that compared the clinical efficacy of a low-dose twice-daily intravenous bolus regimen with a high-dose continuous intravenous infusion regimen in 875 patients with acute bleeding from peptic ulcers. The high-dose regimen was associated with significant reductions in rebleeding, blood transfusion requirements and length of hospital stay. There was no demonstrable difference in mortality or the need for endoscopic hemostatic treatment or surgery. We discuss the strengths and limitations of the evaluated article, as well as the implications for clinical practice.

    Severe imported malaria is an important problem in European countries, where approximately 8,000 cases of Plasmodium falciparum malaria are reported each year. Although the World Health Organization recommends intravenous artesunate (IVA) as the treatment of choice for severe malaria in areas of low transmission, it is rarely used in Europe, because it is not yet available as a drug manufactured under Good Manufacturing Practices. We report a series of eight imported severe falciparum malaria cases treated with IVA combined with intravenous quinine (IVQ). This combined therapy was found to be efficacious, safe, and well-tolerated. The only observed death occurred in a young man who presented 10 days after the onset of symptoms. IVA plus IVQ treatment seems to be an acceptable approach, because the legal risks in using an unlicensed drug for treating a severe malaria case denies the patient the possibility of being treated with the most effective regimen.

  18. The possible role of intravenous lipid emulsion in the treatment of chemical warfare agent poisoning

    Directory of Open Access Journals (Sweden)

    Arik Eisenkraft

    Full Text Available Organophosphates (OPs are cholinesterase inhibitors that lead to a characteristic toxidrome of hypersecretion, miosis, dyspnea, respiratory insufficiency, convulsions and, without proper and early antidotal treatment, death. Most of these compounds are highly lipophilic. Sulfur mustard is a toxic lipophilic alkylating agent, exerting its damage through alkylation of cellular macromolecules (e.g., DNA, proteins and intense activation of pro-inflammatory pathways. Currently approved antidotes against OPs include the peripheral anticholinergic drug atropine and an oxime that reactivates the inhibited cholinesterase. Benzodiazepines are used to stop organophosphate-induced seizures. Despite these approved drugs, efforts have been made to introduce other medical countermeasures in order to attenuate both the short-term and long-term clinical effects following exposure. Currently, there is no antidote against sulfur mustard poisoning. Intravenous lipid emulsions are used as a source of calories in parenteral nutrition. In recent years, efficacy of lipid emulsions has been shown in the treatment of poisoning by fat-soluble compounds in animal models as well as clinically in humans. In this review we discuss the usefulness of intravenous lipid emulsions as an adjunct to the in-hospital treatment of chemical warfare agent poisoning.

    Severe malaria is a medical emergency associated with high mortality. Adequate treatment requires initial parenteral therapy for fast parasite clearance followed by longer acting oral antimalarial drugs for cure and prevention of recrudescence. In a randomized controlled clinical trial, we evaluated the 42-day parasitological outcomes of severe malaria treatment with intravenous artesunate (AS) or intravenous quinine (QNN) followed by oral artemisinin based combination therapy (ACT) in children living in a high malaria transmission setting in Eastern Uganda. We enrolled 300 participants and all were included in the intention to treat analysis. Baseline characteristics were similar across treatment arms. The median and interquartile range for number of days from baseline to parasite clearance was significantly lower among participants who received intravenous AS (2 (1-2) vs 3 (2-3), P malaria symptoms. In this high transmission setting, we observed adequate initial treatment outcomes followed by very high rates of malaria re-infection post severe malaria treatment. The impact of recurrent antimalarial treatment on the long term efficacy of antimalarial regimens needs to be investigated and surveillance mechanisms for resistance markers established since recurrent malaria infections are likely to be exposed to sub-therapeutic drug concentrations. More strategies for prevention of recurrent malaria infections in the most at risk populations are needed. The study was registered with the Pan African Clinical Trial Registry ( PACTR201110000321348 ).

    In Switzerland, the first course of intravenous steroids for treatment of episodes of demyelinating CNS disease is usually administered in an inpatient setting. We prospectively evaluated short term tolerance of treatment with special emphasis on sleep quality. Patients with a first event of presumed demyelinating disease (CIS), multiple sclerosis relapses (MS) or sub-acute disease progression were treated with a 5-day regimen of intravenous methylprednisolone (IVMP) in our inpatient clinic. Patients' experience was documented by self-report questionnaires including a standardised depression scale (ADSL). Laboratory tests were performed on a routine basis. Fasting glucose, blood pressure and pulse were measured before every infusion. Activity and sleep patterns were analysed by wrist actigraphs during the 5 day infusion period and at follow-up after 1-2 months. A total of 66 patients participated in the study. Of these, 55 were steroid treatment naïve, and 11 patients, who had received intravenous steroid relapse treatment before, were admitted because of disabling symptoms. Mood disturbances were reported before steroid treatment, however significantly less often at the end of the steroid pulse and during follow-up. Sleep efficiency as measured by wrist actimetry was high before, during and after steroid treatment. Therapy was well tolerated without severe side effects in CIS and MS patients. Sleep efficiency was not disturbed. In conclusion there are no obstacles to change from an inpatient to an outpatient setting for the steroid treatment of relapses in MS and CIS, but rare psychotic reactions to steroid treatment are not predictable.

    Irritable bowel syndrome (IBS) is notoriously difficult to treat and this situation is unlikely to change until the pathophysiology is better understood. There is no doubt that IBS is a multifactorial condition but it is likely that the relative contribution of the various factors involved varies from patient to patient. Consequently, in some individuals one mechanism may have such a strong effect that its elimination may lead to a substantial improvement in symptoms. This paper describes a patient with severe asthma and IBS where the administration of an anti-Immunoglobulin E (IgE) monoclonal antibody not only improved her asthma but also resulted in an almost complete resolution of her IBS symptoms. This observation suggests that some form of allergic process, which may be mediated by IgE, might be driving IBS in some patients and there is evidence from the literature that atopy is more common in this condition. Therefore, in patients with IBS and atopy where the response to standard treatment is poor, it may be worth considering targeting the allergic diathesis. Possible approaches include skin testing with food antigens followed by an appropriate exclusion diet or pharmacological mast cell stabilization.

    2015-08-01

    Full Text Available Four cases of feline permethrin intoxication are described. The cause of intoxication is the application of canine permethrin spot-on product (Advantix®, Bayer by the owners. Principal clinical guidelines recommends the use of anticonvulsant drugs to treat seizures or neurological symptoms after initial stabilization and dermal decontamination. The use of lipid emulsion had an increasing interest in the last decade for treatment of toxicosis caused by lipophilic drugs as reported in human and in veterinary medical practices. All cats presented in this study, were treated with intravenous lipid emulsion (ILE at variable dosages, and dexmedetomidine was also administered by intravenous way. No adverse reaction such as thrombophlebitis, overload circulation or others was noticed during and after administration of ILE. Dexmedetomidine was proved to be helpful in tranquillizing the cats. All cats were discharged in good condition faster than other cases treated without their use.

    1993-12-01

    We compared the biochemical effects and safety of pamidronate (30 mg a day for 3 consecutive days) versus clodronate (300 mg a day for 3 consecutive days) via intravenous infusion in 14 patients with Paget's disease of bone (PDB). Both drugs induced a decrease in serum alkaline phosphatase levels as well as the elimination of hydroxyproline from urine, an effect most marked in the group treated with pamidronate. The response was maintained for 6 months after the infusion in the majority of the patients. No relevant side effects were found, except post-infusion febricula and in one patient, self-limiting thrombopenia 6 months after the infusion. We conclude that the intravenous infusion of either of the two drugs may constitute a safe and effective alternative for treatment of PDB with marked biochemical activity or resistant to conventional therapy.

    To determine the cost and efficacy of admitting patients for intravenous dihydroergotamine treatment and to identify factors associated with a higher likelihood of response to treatment. We performed a retrospective review of all pediatric hospitalizations from 2001 to 2010 for intravenous dihydroergotamine therapy for headache. Data were collected using the REDcap database and consisted of multiple variables, including preadmission demographics, headache duration, use of prophylactic medications, inpatient therapies including dihydroergotamine dosing, procedures, consultations, total hospital cost, and headache severity at discharge and at follow-up. Seventy-four percent of the 145 individuals who were hospitalized were female. Mean age was 14.9 years. Headache was described as chronic or daily in almost all patients and 28 (19%) had status migrainosus. Sixty-six percent had a first-degree relative with migraine. The average length of stay was 3.7 days, and the average cost was $7569 per hospitalization. Patients received an average of eight doses of dihydroergotamine. At the time of discharge, 63% of patients reported improvement. Follow-up information was available for 68% of the cohort at a median of 42 days after discharge, and 21 of 99 patients (21%) experienced sustained relief of headache. Response to dihydroergotamine was correlated with a lower rate of comorbid diagnoses, lumbar puncture, and outpatient neuroimaging. Response also correlated to less expensive hospitalizations with an average cost of $5379 per hospitalization versus $7105 per hospitalization without positive response. Response was also correlated with a patient receiving more doses of intravenous dihydroergotamine. Although intravenous dihydroergotamine is an effective abortive medication for intractable migraine, it may provide only short-term headache relief in many pediatric patients. Hospitalization is relatively costly with only modest long-term benefit, especially in patients

    A ketogenic diet has been used successfully to treat intractable epilepsy. However, the role of early intravenous initiation of ketogenic diet in the acute phase of super-refractory status epilepticus is not well-described. An intravenous ketogenic diet was administered to a boy with super-refractory status epilepticus. At 24 hours after intravenous ketogenic diet, moderate ketosis appeared, and thiamylal was successfully weaned at 70 hours after admission. An intravenous ketogenic regimen led to subsequent ketosis and seizure control in a child with super-refractory status epilepticus. Early induction of ketosis may be a novel strategy to effectively treat super-refractory status epilepticus. Although there are few data regarding the early use of intravenous ketogenic diet in the treatment of super-refractory status epilepticus, it may be considered an alternative option.

    Full Text Available BACKGROUND AND OBJECTIVE: Postoperative pain treatment in mastectomy remains a major challenge despite the multimodal approach. The aim of this study was to investigate the analgesic effect of intravenous lidocaine in patients undergoing mastectomy, as well as the postoperative consumption of opioids. METHODS: After approval by the Human Research Ethics Committee of the Instituto de Medicina Integral Prof. Fernando Figueira in Recife, Pernambuco, a randomized, blind, controlled trial was conducted with intravenous lidocaine at a dose of 3 mg/kg infused over 1 h in 45 women undergoing mastectomy under general anesthesia. One patient from placebo group was. RESULTS: Groups were similar in age, body mass index, type of surgery, and postoperative need for opioids. Two of 22 patients in lidocaine group and three of 22 patients in placebo group requested opioid (p = 0.50. Pain on awakening was identified in 4/22 of lidocaine group and 5/22 of placebo group (p = 0.50; in the post-anesthetic recovery room in 14/22 and 12/22 (p = 0.37 of lidocaine and placebo groups, respectively. Pain evaluation 24 h after surgery showed that 2/22 and 3/22 patients (p = 0.50 of lidocaine and placebo groups, respectively, complained of pain. CONCLUSION: Intravenous lidocaine at a dose of 3 mg/kg administered over a period of an hour during mastectomy did not promote additional analgesia compared to placebo in the first 24 h, and has not decreased opioid consumption. However, a beneficial effect of intravenous lidocaine in selected and/or other therapeutic regimens patients cannot be ruled out.

    Ketogenic diet (KD) has been used to treat refractory status epilepticus (RSE). KD is a high-fat, restricted-carbohydrate regimen that may be administered with different fat to protein and carbohydrate ratios (3:1 and 4:1 fat to protein and carbohydrate ratios). Other ketogenic regimens have a lower fat and higher protein and carbohydrate ratio to improve taste and thus compliance to treatment. We describe a case of RSE treated with intravenous KD in the Pediatric Intensive Care Unit (PICU). An 8-year-old boy was referred to the PICU because of continuous tonic-clonic and myoclonic generalized seizures despite several antiepileptic treatments. After admission he was intubated and treated with intravenous thiopental followed by ketamine. Seizures continued with frequent myoclonic jerks localized on the face and upper arms. EEG showed seizure activity with spikes on rhythmic continuous waves. Thus we decided to begin KD. The concomitant ileus contraindicated KD by the enteral route and we therefore began IV KD. The ketogenic regimen consisted of conventional intravenous fat emulsion, plus dextrose and amino-acid hyperalimentation in a 2:1 then 3:1 fat to protein and carbohydrate ratio. Exclusive IV ketogenic treatment, well tolerated, was maintained for 3 days; peristalsis then reappeared so KD was continued by the enteral route at 3:1 ratio. Finally, after 8 days and no seizure improvement, KD was deemed unsuccessful and was discontinued. Our experience indicates that IV KD may be considered as a temporary "bridge" towards enteral KD in patients with partial or total intestinal failure who need to start KD. It allows a prompt initiation of KD, when indicated for the treatment of severe diseases such as RSE. Copyright © 2016 European Paediatric Neurology Society. Published by Elsevier Ltd.

    Bisphosphonates have been widely prescribed to postmenopausal women for treatment and prevention of osteoporosis. Given a background of reports of recent safety problems, questions about optimal duration of use, and the patent expiration of Fosamax in February 2008, we accessed data from pharmaceutical marketing research databases to describe trends in dispensed prescriptions and sales of oral bisphosphonates, characteristics of patients and prescribers, and sales of intravenous bisphosphonates for osteoporosis treatment. An estimated 21.3million prescriptions for oral bisphosphonates were dispensed in U.S. retail pharmacies in 2002 that increased 46% to a peak of 31.0million in 2007 and 2008, and declined by 53% in a four year-period to 14.7million in 2012. Sales data (number of packages sold in all settings of care) showed parallel trends (66% increase from 2002 through 2007 and 51% decrease from 2007 through 2012). Similarly, intravenous bisphosphonate sales for osteoporosis treatment grew 3.8-fold from 149.5 thousand packages in 2007 to 561.6 thousand in 2010, followed by a 22% decrease in 2012. Data from an ongoing monthly office-based survey indicated physicians mentioned oral bisphosphonates primarily in visits of older aged Caucasian women with lower body mass for osteoporosis. Frequencies of oral bisphosphonate mentions increased between 2002 and 2012 in visits of Asians and for osteopenia diagnoses. These data indicate a substantial decline in prescriptions and sales of oral (since 2007-2008) and intravenous (since 2010) bisphosphonates for osteoporosis treatment in the United States. Reasons for, and implications of, the decline should be considered for future research. © 2013.

    Induced hypothermia is a promising neuroprotective therapy. We studied the feasibility and safety of hypothermia and thrombolysis after acute ischemic stroke. Intravenous Thrombolysis Plus Hypothermia for Acute Treatment of Ischemic Stroke (ICTuS-L) was a randomized, multicenter trial of hypothermia and intravenous tissue plasminogen activator in patients treated within 6 hours after ischemic stroke. Enrollment was stratified to the treatment time windows 0 to 3 and 3 to 6 hours. Patients presenting within 3 hours of symptom onset received standard dose intravenous alteplase and were randomized to undergo 24 hours of endovascular cooling to 33°C followed by 12 hours of controlled rewarming or normothermia treatment. Patients presenting between 3 and 6 hours were randomized twice: to receive tissue plasminogen activator or not and to receive hypothermia or not. Results- In total, 59 patients were enrolled. One patient was enrolled but not treated when pneumonia was discovered just before treatment. All 44 patients enrolled within 3 hours and 4 of 14 patients enrolled between 3 to 6 hours received tissue plasminogen activator. Overall, 28 patients randomized to receive hypothermia (HY) and 30 to normothermia (NT). Baseline demographics and risk factors were similar between groups. Mean age was 65.5±12.1 years and baseline National Institutes of Health Stroke Scale score was 14.0±5.0; 32 (55%) were male. Cooling was achieved in all patients except 2 in whom there were technical difficulties. The median time to target temperature after catheter placement was 67 minutes (Quartile 1 57.3 to Quartile 3 99.4). At 3 months, 18% of patients treated with hypothermia had a modified Rankin Scale score of 0 or 1 versus 24% in the normothermia groups (nonsignificant). Symptomatic intracranial hemorrhage occurred in 4 patients (68); all were treated with tissue plasminogen activator <3 hours (1 received hypothermia).

    Full Text Available Status epilepticus that cannot be controlled with first- and second-line agents is called refractory status epilepticus (RSE, a condition that is associated with significant morbidity and mortality. Most experts agree that treatment of RSE necessitates the use of continuous infusion intravenous anesthetic drugs such as midazolam, propofol, pentobarbital, thiopental, and ketamine, each of which has its own unique characteristics. This review compares the various anesthetic agents while providing an approach to their use in adult patients, along with possible associated complications.

    Full Text Available Introduction: Puncture wound in diagnostic interventions permits the entry of bacteria into the skin or soft tissue, thus precipitating nosocomial infection, such as erysipelas. There are other risk factors of nosocomial infections including old age, immunosuppressive drugs, and underlying diseases. Pemphigus foliaceus (PF is an autoimmune disease with corticosteroid treatment as the mainstay therapy, which could cause immunosuppression and predispose patients to infection. The objective of this paper was to report erysipelas as one of the manifestations of nosocomial infection in patients under immunosuppressive therapy. Case: A case of erysipelas acquired on the 9th day of hospitalization in a PF patient underwent intravenous dexamethasone injection, with history of puncture wounds on the previous day on the site of erysipelas was reported. The clinical findings of erysipelas were well defined, painful erythema and edema that felt firm and warm on palpation, with blisters and pustules on top. Gram staining from the pustules and blisters fluid revealed Gram (+ cocci. Patient was given 2 grams intravenous ceftriaxone for 7 days and saline wet compress. Improvement on the erysipelas was seen the day after ceftriaxone injection. The patient was discharged after 12 days of hospitalization with improvement both on the PF and the erysipelas. On the next visit 7 days later, the erysipelas lesion disappeared. Conclusion: Puncture wound and immunosuppresive treatment are the factors that could cause erysipelas as a nosocomial infection, and an appropriate treatment of the infection would decrease the functional disability of the patient.

    The therapeutic effects of cyclophosphamide (CP) in the treatment of systemic rheumatic diseases are related to its immune suppressive activity. However effective, the application of CP is restricted due to multiple adverse effects. This retrospective study was conducted to determine the frequency of adverse effects attributed to CP toxicity. The study involved 65 patients (17 male; 48 female) receiving intravenous CP between October 2007 and December 2010. The mean age at onset was 51.2 years (range 19-77 years). The most common diagnoses were systemic sclerosis (20), systemic lupus erythematosus (13) and vasculitis (13). The indications for treatment with CP were interstitial lung disease in the course of systemic diseases (33), vasculitis (24), glomerulonephritis (5) and changes in the central nervous system (3). The patients were administered 400-1000 mg CP in intravenous infusions at 2-16 week intervals, with the addition of sodium 2-sulfanylethanesulfonate (mesna) before and after each pulse. Out of 65 patients 40 (60%) reported adverse effects: infections in 24 (37%), nausea in 19 (29%), vomiting in 11 (17%), abdominal pain in 7 (11%) and pancytopenia in one, leading to cessation of the therapy. No association was found between the frequency of side effects and the treatment duration (p = 0.632), age (p = 0.852), diagnosis (p = 0.171) or nominal dose (p = 0.321). As knowledge about CP continues to increase, this medication remains a safe way to treat many rheumatic diseases.

    The aim of this study was to compare the efficacy and safety of 3 nonsteroidal anti-inflammatory drugs-intravenous tenoxicam, lornoxicam, and dexketoprofen trometamol-for the treatment of patients with renal colic. We conducted a prospective double-blind randomized trial of consecutive adult patients who presented to the emergency department with a chief complaint of acute flank pain and had a clinical diagnosis of suspected acute renal colic. Patients were randomly allocated to receive an intravenous bolus of tenoxicam, lornoxicam, or dexketoprofen trometamol in a blinded fashion. Primary outcome measure of the study was visual analog scale (VAS) score difference at 30 minutes. Secondary outcome measures were VAS scores at 5, 15, and 120 minutes as well as rescue analgesic need at 30 minutes and adverse events during the follow-up period. A total of 445 patients were screened, and 123 patients were enrolled in the study. The mean age was 36 ± 10 years. The mean reduction in VAS pain scores at 30 minutes was 42 ± 26 mm for tenoxicam, 57 ± 23 mm for lornoxicam, and 52 ± 25 mm for dexketoprofen (P = .047). Lornoxicam demonstrated the fastest rate of VAS score reduction over the first 30 minutes. The mean reduction values in VAS pain scores at 5, 15, and 120 minutes were similar among the 3 groups. Rescue analgesics at 30 minutes were required by 16 patients (39%) receiving tenoxicam, 10 patients (24%) receiving lornoxicam, and 8 patients (19%) receiving dexketoprofen (P = .121). No serious adverse events were observed. Intravenous tenoxicam, lornoxicam, and dexketoprofen are all effective in the treatment of renal colic, although lornoxicam appears to reduce VAS pain scores with the fastest rate in this comparison.

    Intravenous iron sucrose and oral iron therapy are the main therapies for iron deficiency anaemia (IDA), but there is still a debate regarding their efficacy and especially as to which one is the best choice during pregnancy. A meta-analysis of randomised controlled trials comparing patients treated with intravenous iron sucrose (intravenous group) with those treated with oral iron (oral group) for IDA during pregnancy was performed. The primary outcomes of interest were mean maternal haemoglobin and serum ferritin levels at the end of treatment. Secondary outcomes were treatment-related adverse events and foetal birth weight. Six randomised controlled trials, involving a total of 576 women, were included in the present review. Significant increases in haemoglobin [mean difference (MD), 0.85; 95% confidence interval (CI), 0.31-1.39; p = 0.002] and ferritin levels (MD, 63.32; 95% CI, 39.46-87.18; p < 0.00001) were observed in the intravenous group. Compared with the oral group, there were fewer adverse events in the intravenous group (risk ratio, 0.50; 95% CI, 0.34-0.73; p = 0.0003). There was no significant difference in birth weight between the two groups. For pregnant women who could not tolerate the side effects of oral treatment or required a rapid replacement of iron stores, intravenous iron sucrose was associated with fewer adverse events and was more effective than regular oral iron therapy. © 2015 S.

    Full Text Available Objectives: To evaluate the knowledge of ophthalmologists regarding local anesthesia toxicity syndrome (LATS and intravenous lipid emulsion used in treatment, and to raise awareness of this issue. Materials and Methods: A questionnaire comprising 14 questions about demographics, local anesthesia (LA use, toxicity, and treatment methods was administered to ophthalmologists at different hospitals. Results: The study included 104 ophthalmologists (25% residents, 67.3% specialists, 7.7% faculty members with a mean age of 35.71±6.53 years. The highest number of participants was from state hospitals (65.4%, and 34.6% of the physicians had been working in ophthalmology for more than 10 years. Seventy-six percent of the participants reported using LA every day or more than twice a week, but 56.7% had received no specific training on this subject. No statistically significant difference was observed between different education levels and the rates of training (p=0.419. Bupivacaine was the most preferred LA and the majority of respondents (97.1% did not use a test dose. Allergy (76% and hypotension (68.3% were the most common responses for early findings of LATS, while cardiac arrest (57.4% and hepatotoxicity (56.4% were given for late findings. The most common responses concerning the prevention of LATS included monitorization (72.4% and use of appropriate doses (58.2%. Symptomatic treatment was selected by 72.4% of respondents and cardiopulmonary resuscitation and antihistamine treatment by 58.8%. Of the ophthalmologists in the study, 62.5% had never encountered LATS. The use of 20% intravenous lipid emulsion therapy for toxicity was known by 65% of the physicians, but only 1 participant stated having used it previously. Conclusion: The importance of using 20% lipid emulsion in LATS treatment and having it available where LA is administered must be emphasized, and there should be compulsory training programs for ophthalmologists on this subject.

    The aim of the study was to investigate the significance of the level of serum 25-hydroxyvitamin D 3 [25-(OH)D 3 ] and interleukin (IL)-6 in serum prior to and after immunoglobulin treatment in children suffering from Kawasaki disease in order to provide a reference for the successful treatment of Kawasaki disease in children. From February, 2013 to February, 2015, 45 patients with Kawasaki disease were enrolled in the observation group. The normal control group comprised 43 healthy volunteers and the feverish control group 46 patients with respiratory infection and fever. Venous blood was collected from each case before and after immunoglobulin treatment and the level of 25-(OH)D 3 and IL-6 in the serum were measured using fluorescent quantitative PCR, enzyme-linked immunosorbent assay and western blotting. Before treatment, the level of 25-(OH)D 3 in the feverish control group was significantly lower than that of the normal control group, while the level of 25-(OH)D 3 in the observation group was significantly higher than that of the normal control group. The level of 25-(OH)D 3 in the feverish control group was lower than the IL-6 level in the normal children, but the difference was not statistically significant (P>0.05). The level 25-(OH)D 3 in the observation group was significantly higher than the IL-6 level in the normal control group. The serum content of 25-(OH)D 3 was significantly higher after the treatment compared to before treatment levels and after treatment IL-6 level was only slightly lower. It was observed that the 25-(OH)D 3 level in the observation group was significantly increased after immunoglobulin treatment and this was positively correlated with the effects of the treatment. The IL-6 level had no significant changes after treatment and had little correlation with the treatment effect. The results suggested that 25-(OH)D 3 may be involved in the occurrence of Kawasaki disease in children and in the aggravation of the disease to some extent.

    Despite evidence from developing world trials that intravenous (IV) artesunate (AS) is superior to IV quinine (Q) in severe falciparum malaria (FM), IV AS remains unlicensed in the UK with national guidelines listing it as an acceptable alternative to IV Q as the drug of choice. We retrospectively evaluate the safety and effectiveness of IV AS in returning travellers with severe FM. We identified adults admitted to the Infectious Diseases unit with severe FM and treated with IV Q (1991-2009) or IV AS (2009-2011). Outcomes included adverse events, mortality, length of stay, admission to intensive care and, where data were available, parasite/fever clearance time and hypoglycaemic events. Of 167 patients, 24 received IV AS and 143 IV Q. There was one potential AS-associated adverse event, a case of late onset haemolysis. Median length of stay (LOS) was significantly shorter for AS (3·5 versus 5 days, P = 0·017), even after adjusting for African ethnicity (for LOS ≥3 days, mhor = 0·33, P = 0·027; crude OR = 0·29, P = 0·013). In the AS group, there were no fatalities (versus five in Q group, NS) and fewer intensive care unit (ICU) admissions (NS). Median parasite clearance was significantly faster in AS (65 versus 85 hours in Q, P = 0·0045) with no hypoglycaemic episodes (versus five in Q). We found IV AS to be safe and effective, with shorter LOS, faster parasite and fever clearance, no fatalities or hypoglycaemic events, and fewer ICU admissions versus IV Q. This corroborates both developing world trials and smaller European case series (although these lacked comparison groups). As well as obvious benefits for patients, there are potential resource savings. A case of late-onset haemolysis may represent an adverse event, particularly as it has been documented elsewhere, warranting further investigation. Nonetheless, our experience suggests IV AS should be first-line for treating severe FM in the UK.

    Severe malaria remains a major cause of mortality and morbidity for children living in many tropical regions. With the emergence of strains of Plasmodium falciparum resistant to both chloroquine and quinine, alternative antimalarial agents are required. The artemisinin group of compounds are rapidly effective in severe disease when given by intramuscular or intravenous injection. However, these routes of administration are not always available in rural areas. In an open, randomized comparison 109 Vietnamese children, aged between 3 months and 14 years, with severe P.falciparum malaria, were allocated at random to receive artemisinin suppositories followed by mefloquine (n = 37), intramuscular artesunate followed by mefloquine (n = 37), or intravenous quinine followed by pyrimethamine/sulfadoxine (n = 35). There were 9 deaths: 2 artemisinin, 4 artesunate and 5 quinine-treated children. There was no difference in fever clearance time, coma recovery, or length of hospital stay among the 3 groups. However, parasite clearance times were significantly faster in artemisinin and artesunate-treated patients than in those who received quinine (P children receiving these drugs had lower peripheral reticulocyte counts by day 5 of treatment than those in the quinine group (P = 0.011). No other adverse effect or toxicity was found. There was no treatment failure in these 2 groups, but 4 patients in the quinine group failed to clear their parasites within 7 d of starting treatment and required alternative antimalarial therapy. Artemisinin suppositories are easy to administer, cheap, and very effective for treating children with severe malaria. In rural areas where medical facilities are lacking these drugs will allow antimalarial therapy to be instituted earlier in the course of the disease and may therefore save lives.

    The goal of this retrospective study was to evaluate the safety and efficacy of ibandronate for bone marrow oedema (BMO) syndrome and stress fracture cases, and to demonstrate an additional field of therapeutic importance-the high-performance athlete. This retrospective study included twenty-five high-performance athletes. Sixty per cent of the athletes were European soccer players and 40.0% other high-class international athletes (3 women and 22 men with an average age of 25.0±4.2), with BMO of the lower trunk or extremity diagnosed by magnetic resonance imaging (MRI). The treatment regimen consisted of high-dose vitamin D supplementation and intravenous ibandronate therapy. The time between the onset of pain and proper diagnosis of BMO was 106.3±104.1 days. Excellent pain reduction (pain at rest and under strain) and improved mobility was reported within the first two weeks after the first ibandronate administration by sixteen patients (64%). The time from first treatment until return to competition (RTC) was on average 102.6±65.2 days in total. If the time from onset of pain until diagnosis was within 40 days, the RTC was significantly reduced (p≤0.05) to almost 50% (63.8±48.1 days) when compared to the athletes with later diagnosis (124.4±63.2 days). The here-applied therapy regimen of intravenous BPs application and vitamin D supplementation in BMO syndrome has a beneficial effect for high-performance athletes. An early diagnosis and rapid treatment start can reduce the RTC significantly. An optimal bone metabolism with sufficient daily calcium and vitamin D intake is crucial and should not only be strived for the professional but also for the recreational athlete.

    Intravenous immunoglobulin (IVIg) reacted with a wide array of human leucocyte antigen (HLA) alleles, in contrast to normal sera, due possibly to the purification of IgG from the pooled plasma. The reactivity of IgG purified from normal sera was compared with that of native sera to determine whether any serum factors mask the HLA reactivity of anti-HLA IgG and whether IgG purified from sera can recognize the HLA types of the corresponding donors. The purified IgG, unlike native sera, mirrored IVIg reactivity to a wide array of HLA-I/-II alleles, indicating that anti-HLA IgG may be masked in normal sera - either by peptides derived from soluble HLA or by those from antibodies. A HLA peptides) masked HLA recognition by the purified IgG. Most importantly, some of the anti-HLA IgG purified from normal sera - and serum IgG from a few donors - indeed recognized the HLA types of the corresponding donors, confirming the presence of auto-HLA antibodies. Comparison of HLA types with the profile of HLA antibodies showed auto-HLA IgG to the donors' HLA antigens in this order of frequency: DPA (80%), DQA (71%), DRB345 (67%), DQB (57%), Cw (50%), DBP (43%), DRB1 (21%), A (14%) and B (7%). The auto-HLA antibodies, when unmasked in vivo, may perform immunoregulatory functions similar to those of therapeutic preparations of IVIg. © 2014 British Society for Immunology.

    The mucinoses of the type of scleredema and scleromyxedema are diseases marked by excessive production of mucin deposits in the skin and subcutaneous tissue, which causes skin hardening. The skin and subcutaneous deposits hamper the movement of limbs, the thorax as well as mouth. The same mechanism also damages other organs (the heart, lungs, oesophagus). It is probably caused by the stimulation of mucin production in fibroblasts by immunoglobulins, frequently monoclonal immunoglobulin. Therefore these diseases are typically associated with monoclonal gammopathy. We describe a cohort of 4 patients, skin manifestations were twice identified as scleredema and twice as scleromyxedema. All the four patients had type IgG monoclonal immunoglobulin and had clonal plasma cells in the bone marrow proven by histologic examination and flow cytometry. Therefore we commenced chemotherapy in all of them. In one case this chemotherapy was ended by a high-dose chemotherapy with transplanting of autologous red blood cells. This therapy attained the complete disappearance of monoclonal immunoglobulin as well as cutaneous and extracutaneous manifestations of scleredema (obstipation). In one case chemotherapy led to partial hematologic remission and partial improvement of skin manifestations. The other two patients did not respond to standard chemotherapy. The condition of one of them resulted in dermato-neuro syndrome (confusion, somnolence passing into coma and grand mal seizure) and improved following an intensive treatment including also intravenous application of immunoglobulins in a dose of 2 g/per 1 kg weight. This patient has now been under long-term treatment with these immunoglobulins, during which the skin symptoms have significantly diminished, but the concentration of monoclonal immunoglobulin has not changed. The fourth patient not responding to standard chemotherapy was treated with intravenous immunoglobulins also in a dose of 2 g/per 1 kg of weight 1× in a month

    Two cases of 10-fold accidental overdose with intravenous paracetamol are presented. Case 1: A 5-month-old child with intussusception received 90 mg/kg intravenous paracetamol over an 8 h period. She was not initially treated with an antidote and developed hepatic impairment. Case 2: A 6-month-old child received a single dose of 75 mg/kg intravenous paracetamol. The child was treated with N-acetylcysteine and remained well without hepatic impairment. Therapeutic errors such as 10-fold overdosing are relatively common in children. Case 1 demonstrates that intravenous paracetamol is a potentially dangerous drug. This should be taken into consideration when prescribing the intravenous formulation. The concentration-time nomogram used following oral paracetamol overdose should be used with caution following intravenous overdose. Significant overdose should be discussed with the National Poisons Information Service whose guidance suggests intervention with antidote following an overdose above 60 mg/kg.

    Full Text Available Elda Righi, Alessia Carnelutti, Antonio Vena, Matteo Bassetti Infectious Diseases Division, Santa Maria della Misericordia University Hospital, Udine, Italy Abstract: The increase in hospitalization due to acute bacterial skin and skin structure infections (ABSSSI caused by resistant pathogens supports the need for new treatment options. Antimicrobial options for ABSSSI that provide broad-spectrum coverage, including gram-negative pathogens and multidrug-resistant gram-positive bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA, are limited. Delafloxacin is a novel fluoroquinolone available as intravenous and oral formulations and is characterized by an increased efficacy in acidic environments and activity on bacterial biofilm. Delafloxacin displays enhanced in vitro activity against MRSA, and enterococci, while maintaining efficacy against gram-negative pathogens and anaerobes. Delafloxacin has been studied for the treatment of ABSSSI and respiratory infections. Phase III studies have demonstrated noninferiority of delafloxacin compared to vancomycin, linezolid, tigecycline, and the combination of vancomycin plus aztreonam in the treatment of ABSSSI. Due to its favorable pharmacokinetic characteristics, the wide spectrum of action, and the potential for sequential therapy, delafloxacin represents a promising option in the empirical and targeted treatment of ABSSSI, both in hospital- and in community-based care. Keywords: bacterial skin and skin structure infections, multidrug-resistant bacteria, methicillin-resistant Staphylococcus aureus, delafloxacin

    Full Text Available Introduction: Newborn children conceived before 32 weeks of incubation are genuinely immune deficient with cord blood centralization of IgG being not as much as half contrasted with those found in infants conceived at full term. Furthermore, exceptionally preterm newborn children have lessened supplement components, polymorphonuclear chemotaxis and are obligated to debilitate their capacity pools. Aims and Objectives: This planned study has been attempted with the accompanying targets, to concentrate on the administration of IVIG in addition with antibiotics to improves the therapeutic consequence of sepsis in preterm neonates. Materials and Methods: Sixty preterm neonates with sepsis were randomly assigned into study and control groups at a tertiary level neonatal intensive care unit, Princess Esra Hospital and Owaisi Hospital & Research Centre, Deccan College of Medical Sciences, Hyderabad, Telangana, India. Study-group was given IVIG in addition to standard treatment. Results: Total 60 patients were enrolled, 30 in study and 30 in control group. There were no gender differences (male 50%, female 50% of neonates enrolled, which is also evident in the study (males 47.7%, females 52.3% and control group (males 52.3%, females 47.7%. Conclusion: Low levels of immunity in preterm neonates results in increased morbidity and mortality in severe infection. Use of IVIG along with the antibiotics and other supportive therapy can improve the outcome.

    To describe the natural history, antenatal and postnatal therapy, and clinical outcomes of Australian patients with fetomaternal/neonatal alloimmune thrombocytopenia (NAIT) recorded in the Australian NAIT registry. Analysis of registry data of Australian mothers treated antenatally for NAIT and any fetus/newborn with thrombocytopenia (TCP) and maternal human platelet antigen (HPA) antibodies. Ninety four potential cases (91 pregnancies; three twin pregnancies) were registered between December 2004 and September 2015 with 76 confirmed or treated as NAIT. NAIT was frequently unanticipated (44 cases, 58%), whilst 32 cases (42%) were anticipated due to personal or family history. In 70/76 cases, the diagnosis of NAIT was made based on HPA antibody results; anti-HPA-1a was most commonly detected (58/70, 82%), followed by anti-HPA-5b (5/70, 7%). Intracranial haemorrhage (ICH) was detected in seven cases (9%). Maternal antenatal therapy resulted in improved clinical outcomes. For antenatally treated cases, whilst 10/29 (34%) neonates had severe TCP, only one ICH was detected. This study provides data on contemporary "real world" management of Australian mothers and babies with NAIT. Antenatal IVIG therapy was associated with better neonatal outcomes. Maternal side-effects and treatment costs were substantial.

    It was shown in experiments in 2160 CBA mice and mice of mixed breed, irradiated with LD 90/30 , that therapeutical administration (subcutaneous or intraperitoneal) of immunoglobulins - homologous (polyglobulin, IgG, IgM) or heterologous - polyglobulin, IgG (from human, equine, canine blood) repeated three times, i.e., 2, 24 and 48 hours after irradiation, not only induced longer survival, but also showed a normalizing effect on the commonly developing dysbacteriosis and increased the amount of intestinal microflora and, in addition, led to the suppression of postirradiation endogenous infection. Enterobacteria, enterococci, staphylococci and yeasts disappeared from the small intestine or their quantity decreased substantially in the treated irradiated mice in contrast to the untreated irradiated mice. In the large intestine, the number of these organisms decreased considerably while the content of lactobacteria increased; no microbes could be found in the internal organs and in the blood (or their content was small). Other conditions being equal, homologous immunoglobulins are more efficient in comparison with heterologous ones, this applying also to preparations containing normal antibodies to tissues.

    Duchenne muscular dystrophy (DMD) is a severe hereditary myopathy. Standard treatment by glucocorticosteroids is limited because of numerous side effects. The aim of this study was to test immunomodulation by human immunoglobulin G (IgG) as treatment in the experimental mouse model (mdx) of DMD. 2 g/kg human IgG compared to human albumin was injected intraperitoneally in mdx mice at the age of 3 and 7 weeks. Advanced voluntary wheel running parameters were recorded continuously. At the age of 11 weeks, animals were killed so that blood, diaphragm, and lower limb muscles could be removed for quantitative PCR, histological analysis and ex vivo muscle contraction tests. IgG compared to albumin significantly improved the voluntary running performance and reduced muscle fatigability in an ex vivo muscle contraction test. Upon IgG treatment, serum creatine kinase values were diminished and mRNA expression levels of relevant inflammatory markers were reduced in the diaphragm and limb muscles. Macrophage infiltration and myopathic damage were significantly ameliorated in the quadriceps muscle. Collectively, this study demonstrates that, in the early disease course of mdx mice, human IgG improves the running performance and diminishes myopathic damage and inflammation in the muscle. Therefore, IgG may be a promising approach for treatment of DMD. Two monthly intraperitoneal injections of human immunoglobulin G (IgG) improved the early 11-week disease phase of mdx mice. Voluntary running was improved and serum levels of creatine kinase were diminished. In the skeletal muscle, myopathic damage was ameliorated and key inflammatory markers such as mRNA expression of SPP1 and infiltration by macrophages were reduced. The study suggests that IgG could be explored as a potential treatment option for Duchenne muscular dystrophy and that pre-clinical long-term studies should be helpful. © 2015 International Society for Neurochemistry.

    To study the impact of preprocedure intravenous urography (IVU) on the outcome of SWL for renal stones. Two hundred patients with radiopaque renal stones IVU before the start of SWL, whereas patients in the second group (n = 100) underwent SWL without IVU. Thirteen patients in the IVU group and seven patients in the no-IVU group were excluded from the study. Patients in both groups received the same treatment and follow-up protocols. Intraoperative and postoperative complications were evaluated in all patients. An endpoint assessment by plain film was done 3 months after the conclusion of treatment to evaluate the success and stone-free rates. The success rate (81.6% in group 1 v 77.4% in group 2), stone-free rate (65.5% v 62.3%), re-treatment rate (59.8% v 69.9%), auxiliary-procedure rate (6.9% v 5.4%), and complication rate (11.5% v 14%) were similar in the two groups. It is not necessary to obtain an IVU for patients who have renal calculi with no or minimal back pressure before scheduling them for SWL, thus minimizing the cost, avoiding exposure to contrast medium, and reducing radiation exposure.

    Full Text Available Abstract Background Intravenous (IV artesunate is the treatment of choice for severe malaria. In Europe, however, no GMP-manufactured product is available and treatment data in European travellers are scarce. Fortunately, artesunate became available in the Netherlands and Belgium through a named patient programme. This is the largest case series of artesunate treated patients with severe malaria in Europe. Methods Hospitalized patients treated with IV artesunate between November 2007 and December 2010 in the Netherlands and Belgium were retrospectively evaluated. Patient characteristics, treatment and clinical outcome were recorded on a standardized form and mortality, parasite clearance times and the occurrence of adverse events were evaluated. Results Of the 68 treated patients, including 55 with severe malaria, two patients died (2/55 = 3.6%. The mean time to 50% parasite clearance (PCT50, 90% and 99% were 4.4 hours (3.9 - 5.2, 14.8 hours (13.0 - 17.2, and 29.5 hours (25.9 - 34.4 respectively. Artesunate was well tolerated. However, an unusual form of haemolytic anaemia was observed in seven patients. The relationship with artesunate remains uncertain. Conclusions Data from the named patient programme demonstrate that IV artesunate is effective and well-tolerated in European travellers lacking immunity. However, increased attention needs to be paid to the possible development of haemolytic anaemia 2-3 weeks after start of treatment. Treatment of IV artesunate should be limited to the period that IV treatment is required and should be followed by a full oral course of an appropriate anti-malarial drug.

    Several guidelines advocate the same treatment approaches for both early disseminated Lyme borreliosis, manifested as multiple erythema migrans (EM), and early localized Lyme borreliosis, manifested as solitary EM. Oral doxycycline (100 mg q12h) was compared on a non-inferiority premise with intravenous ceftriaxone (2 g q24h) for 14 days in 200 adult European patients with multiple EM in an open-label alternate-treatment observational trial performed in a single-centre university hospital. Treatment outcome was assessed at 14 days and at 2, 6 and 12 months post-enrolment. Non-specific symptoms in patients and 192 control subjects without a history of Lyme borreliosis were evaluated and compared. This trial was registered at http://clinicaltrials.gov (identifier NCT01163994). At the 12 month visit, 4/82 (4.9%) multiple EM patients prescribed doxycycline and 6/88 (6.8%) multiple EM patients prescribed ceftriaxone showed incomplete response manifested predominantly as post-Lyme symptoms (1.9% difference, upper limit of 95% CI 5.1%). The upper limit of 95% CI for the difference in proportion of patients with incomplete response between doxycycline and ceftriaxone groups did not exceed the predetermined non-inferiority margin of 10%. The frequency of non-specific symptoms in patients was similar to that in controls. The 14 day oral doxycycline was not inferior to the 14 day intravenous ceftriaxone in treatment of adult European patients with early disseminated Lyme borreliosis manifested as multiple EM. The frequency of non-specific symptoms in patients was similar to that in controls without a history of Lyme borreliosis. © The Author(s) 2018.

    In 60 women with breast cancer the effect of radical mastectomy and radiotherapy on the serum levels of immunoglobulins IgA, IgM and IgC was studied. It was demonstrated that surgical treatment had no significant effect on the levels of immunoglobulins in the serum. Following X-ray therapy a fall occurred in the level of immunoglobulins, mainly of the IgA class, less in that of IgM and IgG. Radiation-induced disturbances were greatest immediately after completion of treatment and disappeared only after about 12 months. The degree of disturbances in the level of IgA was increased when the thymus was exposed to radiation, this was less evident in the level of IgG. (author)

    Immune thrombocytopenia (ITP) in children is usually a benign, self-limiting disorder. An acute Epstein-Barr virus (EBV) infection usually causes atypical lymphocytosis and mild decrease in platelets. Severe thrombocytopenia is an extremely rare complication. Anti-D immunoglobulin has been used for treatment of ITP in Rh(D)-positive nonsplenectomized patients. Severe hemolysis and acute renal failure are extremely rare complications that may be aggravated by the presence of an acute EBV infection. It is believed that anti-D immunoglobulin triggers an unusual virus-induced immune response causing hemolysis. We present a 4-year-old girl with ITP caused by an acute EBV infection that developed acute kidney injury following treatment with anti-D immunoglobulin. The patient recovered completely from thrombocytopenia and renal dysfunction. Intravascular hemolysis and acute kidney injury are consistent with anti-D immunoglobulin mechanism of action. Pediatric patients treated with anti-D immunoglobulin for ITP should be closely monitored for signs and symptoms of hemolysis that may be aggravated by the presence of EBV infection leading to impaired renal function.

Bisphosphonate treatment for bone metastases is frequently administered via intravenous infusion, while a newer treatment is administered as a subcutaneous injection. This study estimated the impact of these treatment modalities on health state preference. Methods: Participants from the UK general population completed time trade-off interviews to assess the utility of health state vignettes. Respondents first rated a health state representing cancer with bone metastases. Subsequent health states added descriptions of treatment modalities (ie, injection or infusion to this basic health state. The two treatment modalities were presented with and without chemotherapy, and infusion characteristics were varied by duration (30 minutes or 2 hours and renal monitoring. Results: A total of 121 participants completed the interviews (52.1% female, 76.9% white. Cancer with bone metastases had a mean utility of 0.40 on a standard utility scale (1 = full health; 0 = dead. The injection, 30-minute infusion, and 2-hour infusion had mean disutilities of −0.004, −0.02, and −0.04, respectively. The mean disutility of the 30-minute infusion was greater with renal monitoring than without. Chemotherapy was associated with substantial

    Paradoxical hyperactivity (PH) is a known complication of sedation in children, especially with barbiturates such as pentobarbital. The accompanying inconsolable irritability and agitation, similar to behaviors reported in children with attention deficit hyperactivity disorder (ADHD), is uncomfortable for the child and anxiety-provoking for parents and health-care workers. Our objective was to describe our experience with oral (PO) and intravenous (IV) caffeine as a treatment for sedation-induced PH. From January 2000 to April 2003, 19,894 children were sedated in our institution for radiology procedures. Of these, 360 children were diagnosed with PH. A total of 229 children exhibiting symptoms of PH after sedative administration were treated with PO caffeine ( n=88; 43 boys, 45 girls; mean age 4.5 years, mean weight 18.7 kg) or IV caffeine ( n=131; 73 boys, 58 girls; mean age 4.8 years, mean weight 20.1 kg) or both ( n=10; 8 boys, 2 girls; mean age 5.0 years, mean weight 19.9 kg). A positive effect was defined as a decrease in agitation, crying, or hyperactivity within 40 min of caffeine administration. A control group ( n=45) was obtained from those 141 children who experienced post-sedation PH but were not treated with caffeine, and matched for age and sex with samples of children treated with IV caffeine ( n=45) and PO caffeine ( n=45). Children treated intravenously received the equivalent of 20 mg/kg caffeine citrate (to a maximum of 200 mg). Of those treated with IV caffeine, 82/131 (63%) showed a positive effect, and returned to baseline behavioral status after an average of 33 min (SD=23 min). The untreated control group required a significantly longer time to recover ( Pcaffeine. Children treated orally received approximately 1.0-2.5 mg/kg caffeine in Mountain Dew (Pepsi-Cola Company), and 36/88 (41%) showed a positive effect and returned to baseline behavioral status after an average of 42 min (SD=27 min). Of the 10 children treated with both PO and IV

    Approved use of intravenous alteplase for ischemic stroke offers net benefit. Pooled randomized controlled trial analysis suggests additional patients could benefit but others be harmed with treatment initiated beyond 4·5 h after stroke onset. We proposed prognostic scoring methods to identify a strategy for patient selection. We selected 500 patients treated by intravenous alteplase and 500 controls from Virtual International Stroke Trials Archive, matching modified Rankin score outcomes to those from pooled randomized controlled trial 4·5-6 h data. We ranked patients by prognostic score. We chose limits to optimize our sample for a net treatment benefit significant at P = 0·01 by Cochran-Mantel-Haenszel test and by ordinal regression. For validation, we had these applied to the pooled randomized controlled trial data for 4·5-6 h, testing for net benefit by Cochran-Mantel-Haenszel test, ordinal regression, and also by dichotomized outcomes: modified Rankin score 0-1, mortality and parenchymal hemorrhage type 2 bleeds. All analyses were adjusted for age and National Institutes of Health Stroke Scale. In the training dataset, limits of 56-95 on a prognostic score retained 714 patients in whom there was net benefit significant at P = 0·01. When applied to the 1120 patients in the pooled randomized controlled trial 4·5-6 h dataset, score limits of 56-95 retained 711 patients and gave odds ratio for improved modified Rankin score distribution of 1·13, 95% confidence interval 0·87-1·47, Cochran-Mantel-Haenszel P = 0·89. More patients achieved modified Rankin score 0-1 (odds ratio 1·44, 1·02-2·05, P = 0·04) but mortality and parenchymal hemorrhage type 2 bleeds were increased: odds ratio 1·56, 1·01-2·40, P = 0·04; odds ratio 15·6, 3·7-65·8, P = 0·0002, respectively. Selection of patients between 4·5 and 6 h based on simple clinical measures failed to deliver a population in whom the alteplase effect would be safe

    Graves' orbitopathy (GO) is the commonest extrathyroidal feature of Graves' disease. For active, moderate to severe GO intravenous glucocorticoid pulse therapy (ivGCS) is the first-line treatment, which might be followed by oral glucocorticoid therapy. Glucocorticoid treatment, especially in the time of withdrawal, carries a risk of adrenal insufficiency. The aim of this study was to assess the pituitary-adrenal axis function in patients with GO before and at the cessation of ivGCS, and after further oral glucocorticoid therapy. Twenty patients received treatment in accordance with the EUGOGO protocol (500 mg methylprednisolone once a week for six weeks, then 250 mg once a week for another six weeks) followed by oral prednisone at a gradually decreasing dose from 30 mg/day over a three-month period. Adrenal function was evaluated directly before the ivGCS, before the last pulse, and after oral glucocorticoid intake. The assessment consisted of clinical evaluation, and measurements of morning total serum cortisol (TSC) and plasma adrenocorticotropic hormone (ACTH). Patients with decreased cortisol level underwent ACTH stimulation test with TSC measurements before, and 30 minutes and 60 minutes after the administration of synthetic ACTH. All patients before and at the cessation of ivGCS treatment demonstrated intact adrenal function. One patient after prednisone therapy presented decreased adrenal reserve. TSC concentration was significantly lower after the ivGCS (p = 0.025) and oral glucocorticoid therapy (p = 0.0006) in comparison to evaluation before therapy. Therapy with ivGCS for GO does not lead to secondary adrenocortical insufficiency. Further low-dose oral glucocorticoid therapy may result in secondary adrenocortical insufficiency in some patients.

    Intravenous human immunoglobulins dominate in the treatment of autoimmune neuropathies. We introduce intrathecal application as a new option for experimental autoimmune neuritis in Lewis rats. After immunisation with neuritogenic P2 peptide, we show a therapeutic and preventive effect of intrathecal human immunoglobulins (5-40mg/kg) on clinical and electrophysiological neuritis signs. Histology corroborated a lower degree of inflammation, demyelination, ICAM-1-dependent blood-nerve-barrier permeability and complement activation in the sciatic nerve. After preventive application, immunoglobulins induced a Th2 cytokine shift in the peripheral nerves already before clinical neuritis signs. Intrathecal immunoglobulin application could be a novel immunomodulatory option for autoimmune neuropathies. Copyright © 2017 Elsevier B.V. All rights reserved.

    Patients have to be informed about the risks and benefits of medicinal products derived from human plasma. No study has examined the patient's perspective yet. Our objective was to assess perceived benefits and risks of immunoglobulins administration from the patient's point of view. Thirty-four patients receiving subcutaneous or intravenous immunoglobulins for chronic disorders at a single university hospital were asked to complete a survey. Although the level of comfort was high, the results revealed variable and incomplete knowledge, in particular about the nature of the treatment. Greater efforts should be made by health professionals to provide information to patients about plasma-derived medicinal products.

    Persistent low-level hypotension represents a barrier to discharging patients from the intensive care unit (ICU). Midodrine may be an effective adjunct to wean intravenous (IV) vasopressors and permit ICU discharge. We tested the hypothesis that midodrine, given to patients on IV vasopressors who otherwise met ICU discharge criteria, increased the magnitude of change in IV vasopressor rate. This was a prospective, observational study in 20 adult surgical ICU patients who met ICU discharge criteria except for an IV vasopressor requirement. We compared the change in phenylephrine equivalent rates during the day before midodrine to the change in phenylephrine equivalent rates after midodrine initiation and analyzed changes in total body fluid balance, heart rate, mean arterial pressure, and white blood cell count during this period. Patients received 41.0±33.4 μg/min of phenylephrine equivalents and the change in IV vasopressor rate (slope) decreased significantly from -0.62 μg/min per hour of phenylephrine equivalents before midodrine to -2.20 μg/min per hour following the initiation of midodrine treatment (P=.012). Change in total body fluid balance, heart rate, mean arterial pressure, and white blood cell count did not correlate with change in IV vasopressor rate. Midodrine treatment was associated with an increase in the magnitude of decline of the IV vasopressor rate. Oral midodrine may facilitate liberation of surgical ICU patients from an IV vasopressor infusion, and this may affect discharge readiness of patients from the ICU. Copyright © 2013 Elsevier Inc.

    Intravenous ribavirin has been reported to be an effective treatment for haemorrhagic fever with renal syndrome (HFRS) caused by Hantaan virus in Asia. However, its therapeutic benefits for HFRS caused by Puumala virus (PUUV) in Europe are still unknown. A randomized, open-label study of efficacy and safety of intravenous ribavirin in the treatment of HFRS was conducted in the European part of Russia. Seventy-three patients with suspected HFRS within 4 d of the onset of the disease were randomized to receive either intravenous ribavirin (33 mg/kg, followed by 16 mg/kg given every 6 h for 4 d and by 8 mg/kg given every 8 h for 3 d) plus standard therapy (n = 37) or standard therapy alone (n = 36). The primary outcome was the average change from baseline in viral load over time estimated as area under the viral load curve minus baseline (AUCMB). Fifty-five patients with HFRS confirmed by nested reverse transcriptase - polymerase chain reaction (PCR) assay were included in the assessment of the efficacy. All patients entered into the clinical trial were included in the assessment of the safety. PUUV was detected in all cases of confirmed HFRS. Viral load kinetics were similar in both treatment groups. Significantly more patients receiving ribavirin than standard therapy experienced low haemoglobin level (95% vs 36%), hyperbilirubinemia (81% vs 3%), sinus bradycardia (43% vs 14%), and rash (19% vs 0%). Results of the study showed insufficient efficacy and safety of intravenous ribavirin in the treatment of HFRS caused by PUUV.

    Intravenous immunoglobulin (IVIG) replacement therapy has been used in immune deficiency diseases for more than 50 years. The indications for this treatment have evolved, however, and IVIG therapy is now used in various diseases in which the immune system plays a prominent role. IVIG therapy has carved out a niche in dermatology for the treatment of such conditions as dermatomyositis, autoimmune bullous diseases, and toxic epidermal necrolysis. Special attention has been paid to this therapy in recent years. New guidelines have been published and should be taken into consideration in dermatology. This review provides a practical guide to IVIG use in our specialty. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    Bone and joint infection in adults arises most commonly as a complication of joint replacement surgery, fracture fixation and diabetic foot infection. The associated morbidity can be devastating to patients and costs the National Health Service an estimated £20,000 to £40,000 per patient. Current standard of care in most UK centres includes a prolonged course (4-6 weeks) of intravenous antibiotics supported, if available, by an outpatient parenteral antibiotic therapy service. Intravenous therapy carries with it substantial risks and inconvenience to patients, and the antibiotic-related costs are approximately ten times that of oral therapy. Despite this, there is no evidence to suggest that oral therapy results in inferior outcomes. We hypothesise that, by selecting oral agents with high bioavailability, good tissue penetration and activity against the known or likely pathogens, key outcomes in patients managed primarily with oral therapy are non-inferior to those in patients treated by intravenous therapy. The OVIVA trial is a parallel group, randomised (1:1), un-blinded, non-inferiority trial conducted in thirty hospitals across the UK. Eligible participants are adults (>18 years) with a clinical syndrome consistent with a bone, joint or metalware-associated infection who have received ≤7 days of intravenous antibiotic therapy from the date of definitive surgery (or the start of planned curative therapy in patients treated without surgical intervention). Participants are randomised to receive either oral or intravenous antibiotics, selected by a specialist infection physician, for the first 6 weeks of therapy. The primary outcome measure is definite treatment failure within one year of randomisation, as assessed by a blinded endpoint committee, according to pre-defined microbiological, histological and clinical criteria. Enrolling 1,050 subjects will provide 90 % power to demonstrate non-inferiority, defined as less than 7.5 % absolute increase in treatment

  2. Efficacy and safety of adding mizoribine to standard treatment in patients with immunoglobulin A nephropathy: A randomized controlled trial

    2017-06-01

    Full Text Available Background: Mizoribine (MZR is an immunosuppressive drug used in Japan for treating patients with lupus nephritis and nephrotic syndrome and has been also reportedly effective in patients with immunoglobulin A (IgA nephropathy. However, to date, few randomized control studies of MZR are performed in patients with IgA nephropathy. Therefore, this prospective, open-label, randomized, controlled trial aimed to investigate the efficacy and safety of adding MZR to standard treatment in these patients, and was conducted between April 1, 2009, and March 31, 2016, as a multicenter study. Methods: Patients were randomly assigned (1:1 to receiving standard treatment plus MZR (MZR group or standard treatment (control group. MZR was administered orally at a dose of 150 mg once daily for 12 months. Results: Primary outcomes were the percentage reduction in urinary protein excretion from baseline and the rate of patients with hematuria disappearance 36 months after study initiation. Secondary outcomes were the rate of patients with proteinuria disappearance, clinical remission rate, absolute changes in estimated glomerular filtration rate from baseline, and the change in daily dose of prednisolone. Forty-two patients were randomly assigned to MZR (n = 21 and control groups (n = 21. Nine patients in MZR group and 15 patients in the control group completed the study. No significant differences were observed between the two groups with respect to primary and secondary outcomes. Conclusion: The addition of MZR to standard treatment has no beneficial effect on reducing urinary protein excretion and hematuria when treating patients with IgA nephropathy.

    Intravenous glucocorticoids are recommended for multiple sclerosis (MS). However, they can be inconvenient and expensive. Due to their convenience and low cost, oral glucocorticoids may be an alternative treatment. Recently, several studies have shown that there is no difference in efficacy and safety between oral methylprednisolone (oMP) and intravenous methylprednisolone (ivMP). We sought to assess the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses in this meta-analysis. Randomized controlled trials (RCTs) evaluating the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses were searched in PubMed, Cochrane Library, Medline, EMBASE and China Biology Medicine until October 25, 2016, without language restrictions. The proportion of patients who had improved by day 28 was chosen as the efficacy outcome. We chose the risk ratio (RR) to analyze each trial with the 95% confidence interval (95% CI). We also used the fixed-effects model (Mantel-Haenszel approach) to calculate the pooled relative effect estimates. A total of 5 trials were identified, which included 369 patients. The results of our meta-analysis revealed that no significant difference existed in relapse improvement at day 28 between oMP and ivMP (RR 0.96, 95% CI 0.84 to 1.10). No evidence of heterogeneity existed among the trials (P = 0.45, I2 = 0%). Both treatments were equally safe and well tolerated except that insomnia was more likely to occur in the oMP group compared to the ivMP group. Our meta-analysis reveals strong evidence that oMP is not inferior to ivMP in increasing the proportion of patients experiencing clinical improvement at day 28. In addition, both routes of administration are equally well tolerated and safe. These findings suggest that we may be able to replace ivMP with oMP to treat MS relapses.

    There is little evidence on the prognostic influence of intravenous nitrates in patients with acute heart failure. Our purpose was to determine the influence of this treatment on early mortality and new visits. Prospective, multicenter cohort study of patients with acute heart failure in an emergency room during 2 periods (May 2009 and November-December 2011). Patients with systolic blood pressure > 110mmHg were included, grouped according to whether they received intravenous nitroglycerin or not. Endpoints were mortality at 3, 7, 14, and 30 days and new visits at 30 days. The propensity score was estimated by logistic regression to determine the prognostic influence of the treatment. We included 3178 of 4897 individuals. A total of 308 (9.7%) had died within 30 days and 465 (17%) attended new visits. The mean (standard deviation) age was 79.5 (10.0) years, and 796 (25%) patients received intravenous nitrates. After matching, there were 685 individuals in each group. The hazard ratio for 30-day mortality with nitrates was 1.21 (95% confidence interval, 0.87-1.70) and was 0.93 for new visits (95% confidence interval, 0.71-1.22). The results were similar for mortality at 3, 7, and 14 days (hazard ratio = 1.05 [95% confidence interval, 0.56-1.96], hazard ratio = 1.20 [95% confidence interval, 0.74-1.94], and hazard ratio = 1.23 [95% confidence interval, 0.82-1.84], respectively). In the presence of hypertensive pulmonary edema, the nitrates group showed a hazard ratio of 0.88 (95% confidence interval, 0.47-1.63) for 30-day mortality. Intravenous nitrates do not influence early mortality or new visits in patients with acute heart failure. Copyright © 2014 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

    2014-06-01

    Intravenous immunoglobulin therapy is of proven effect in chronic inflammatory neuropathies, including chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). In more recent years, there have been a number of anecdotal case reports and small series, followed by a few trials of variable design, of subcutaneous immunoglobulin therapy in these neuropathies. To date, limited evidence suggests that the subcutaneous route may be a more clinically effective, better-tolerated, at least cost-equivalent and a more patient-friendly option than the still more used intravenous alternative. Long-term efficacy is not as yet established in neuropathic indications by randomised controlled clinical trial evidence, and it is likely that the subcutaneous route may not be suitable in all cases with some hints to this effect appearing from the limited data available to date. Further studies are ongoing, including those of dose comparison, and more are likely to be planned in future. The literature on the use of subcutaneous immunoglobulin therapy in chronic inflammatory neuropathy is reviewed here. The current use in clinical practice, day-to-day benefits, including quality of life measures and health economics as published thus far, are evaluated. The limitations of this form of treatment in CIDP and MMN are also analysed in the light of current literature and taking into account the remaining unknowns. Future prospects and research with this mode of immunoglobulin therapy administration are discussed.

    Immunoglobulin replacement therapy (IRT) is standard treatment for patients with primary immunodeficiency (PID). Because most of the patients with PID will require long life-time immunoglobulin replacement therapy, the quality of the prescribed products is of utmost importance. The IRT is generally administered either intravenously (abbreviated IVIG), or subcutaneously (abbreviated SCIG). Both routes have been demonstrated to be effective. The preferred route may vary at different times during a given patient's life. Options are therefore not fixed and the choice of route for immunoglobulin therapy will depend on several factors, including patient characteristics, clinical indication, venous access, side effects, rural or remote location, treatment compliance and patient preference. Many years ago, immunoglobulin therapy was associated with side effects which may compromise patient's compliance and quality of life of the patients. Most of the side effects were related to impurities. Recently, major advances in the manufacturing process have been made and new processes, such as the Quality by design (QbD) approach were added into the manufacturing steps to ensure patients tolerability and safety. Due to the improved purity of the immunoglobulin products obtained by these processes, the incidence of side effects is lower, while the ways of administration of Ig therapy and the choice of the regimen has widened to suit patient's preference and needs.

    The discovery of immunoglobulin E (IgE) was a breakthrough in the field of allergy and immunology. Our understanding of mechanisms of allergic reactions and the role of IgE in these disorders has paralleled to the discovery of treatment modalities for patients with allergy. The first clue to the existence of a substance responsible for hypersensitivity reactions was demonstrated in 1921 by Prausnitz and Kustner, and after four decades it was identified as an immunoglobulin subclass by Ishizakas and co-workers. In 1968, the WHO International Reference Centre for Immunoglobulins announced the presence of a fifth immunoglobulin isotype, IgE. Copyright © 2016 Elsevier B.V. All rights reserved.

    Immunoglobulin (Ig)G4-associated cholangitis (IAC) is one of the common organ manifestations of IgG4-related systemic disease (ISD). IAC and autoimmune pancreatitis (AIP) may mimic sclerosing cholangitis, cholangiocarcinoma, or pancreatic carcinoma. Diagnosis is based on a combination of clinical, biochemical, radiological, and histological findings.To study the clinical presentation of and treatment strategy for IAC, we reviewed clinical, serologic, and imaging characteristics, as well as treatment response, in 39 patients with IAC. The majority of patients were men (82%). Clinical features on presentation included obstructive jaundice in 26 patients (67%) and abdominal pain in 20 (51%). Positive IgG4 immunostaining was seen in 27 patients. The median serum IgG4 level before treatment was 769.4 mg/dL (range, 309.1-1229.7 mg/dL). After the steroid therapy, the median serum IgG4 level in 23 patients was 247.0 mg/dL (range, 139.0-355.0 mg/dL). Cholangiograms were available in 36 (92%) patients. Stenosis of the lower part of the common bile duct was found in 26 of 39 patients. Stenosis was diffusely distributed in the intra- and extrahepatic bile ducts in 14 of 39 patients. Additionally, strictures of the bile duct were detected in the hilar hepatic lesions in 27 of 39 patients. AIP was the most frequent comorbidity (35/39 in this study) of IAC. Other affected organs included eyes (n = 6), salivary glands (sialadenitis, n = 10), lymph nodes (mediastinal and axillary, n = 3), kidneys (n = 2), and the retroperitoneum (retroperitoneal fibrosis, n = 2).Regarding treatment, 29 patients were treated with steroids, of whom one underwent pancreatoduodenectomy, and one underwent choledochojejunostomy. Eight patients were treated with biliary stents. The remaining 19 patients took prednisolone alone. Eight patients achieved spontaneous resolution. Four patients with suspected pancreatic cancer or cholangiocarcinoma underwent surgery, including 2

    Immune complex deposition in the subepithelial zone of glomerular capillaries can lead to membranous glomerulopathy. To present the case of a 23-year-old man with X-linked agammaglobulinemia (XLA) who developed idiopathic membranous glomerulopathy while receiving intravenous immunoglobulin (IVIG). We performed an immunological workup, genetic testing, and a renal biopsy. XLA was confirmed with less than 0.02% CD19+ cells in the blood after sequence analysis revealed a nonfunctional BTK gene. The patient presented with microhematuria, which persisted for 3 years and spanned treatment with 5 different preparations of intravenous gammaglobulin. Immunohistochemistry revealed membranous glomerulopathy. Although endogenous serum immunoglobulin (Ig) production is severely impaired in XLA, rare B lymphocytes that have managed to mature can produce functional IgG antibodies. The pathogenic immune complexes could reflect IVIG reacting with polymorphic autoantigens, an endogenous IgG-producing clone reacting with a common idiotype present in the IVIG, or both.

    Immunoglobulin class A is the main protein of the mucosal immune system. Selective immunoglobulin A deficiency (sIgAD) is the most common primary immunodeficiency in Caucasians. sIGAD is strongly associated with the certain major histocompatibility complex region. Most individuals with sIgAD are asymptomatic and identified coincidentally. However, some patients may present with recurrent infections, allergic disorders and autoimmune manifestations. Several autoimmune diseases, such as systemic lupus erythematosus, diabetes mellitus type 1, Graves disease and celiac disease, are associated with an increased prevalence of sIgAD. Screening for sIgAD in coeliac disease is essential. Patients need treatment of associated diseases. It is also known that IgA deficiency may progress into a common variable immunodeficiency (CVID). Pathogenesis and molecular mechanism involved in sIgAD should be elucidated in the future.

    Reinfection after two-stage revision hip arthroplasty (RHA) is still a complex issue. Only few studies revealed the factors affecting the success rate in the treatment of periprosthetic hip infection (PHI), especially risk factors. A retrospective study was conducted using records of 30 patients underwent two-stage RHA for infected total hip arthroplasty (THA). Treatment was defined as successful if a patient did not need any reoperation or invasive procedure such as image-guided drainage during the two years after reimplantation. Treatment was defined as failure if any surgery or invasive procedure or long-term antibiotic suppression was considered necessary to control infection. Four patients had infection recurrence defined as failed and three of them had intravenous drug abuse. Twenty-six patients had no infection recurrence at the end of follow-up and one of them had intravenous drug abuse but quitting after surgery. We suggest that once adequate cleaning up achieved, risk of reinfection may be little even in immunocompromised patients with RHA because of relative less old age than those with revisional total knee arthroplasty. Patients of the reinfection group were younger and non-obese with adequate nutritional status. We may consider intravenous drug abuse could take a great toll on health and lead to reinfection. Finally, we suggest performing the gold-standard two-stage reimplantation technique to manage cases with infection, educating drug abusers regarding the risk of surgical failure, and implementing a quitting program at least 1 year before the index surgery.

    Full Text Available Immunoglobulins are important biomarkers to evaluate the immune status or development of infectious diseases. To provide timely clinical treatments, it is important to continuously monitor the level of multiple immunoglobulins. Localized surface plasmon resonance (LSPR-based nanoplasmonic sensors have been demonstrated for multiplex immunoglobulins detection. However, the sensor fabrication process is usually slow and complicated, so it is not accessible for large-area and batch fabrication. Herein, we report a large-area (2 cm × 2 cm nanofabrication method using physical vapor deposition followed by a rapid thermal annealing treatment. To optimize the sensor performance, we systematically characterized three fabrication conditions, including (1 the deposition thickness; (2 the maximum annealing temperature, and (3 the annealing time. The corresponding absorbance spectrum profile and surface morphology of the nanostructures were observed by a UV-VIS spectrometer and atomic force microscopy. We then tested the sensitivity of the sensor using a glucose solution at different concentrations. The results showed that the sensor with 10 nm gold deposition thickness under 5-min 900 °C rapid thermal annealing can achieve the highest sensitivity (189 nm RIU−1. Finally, we integrated this nanoplasmonic sensor with a microchannel and a motorized stage to perform a 10-spot immunoglobulin detection in 50 min. Based on its real-time, dynamic and multi-point analyte detection capability, the nanoplasmonic sensor has the potential to be applied in high-throughput or multiplex immunoassay analysis, which would be beneficial for disease diagnosis or biomedical research in a simple and cost-effective platform.

With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients.

    Full Text Available Pain is the most common complaint in emergency department and there are several methods for its control. Among them, pharmaceutical methods are the most effective. Although intravenous morphine has been the most common choice for several years, it has some adverse effects. There are many researches about intravenous acetaminophen as an analgesic agent and it appears that it has good analgesic effects for various types of pain. We searched some electronic resources for clinical trials comparing analgesic effects of intravenous acetaminophen vs. intravenous morphine for acute pain treatment in emergency setting.In two clinical trials, the analgesic effect of intravenous acetaminophen has been compared with intravenous morphine for renal colic. The results revealed no significant difference between analgesic effects of two medications. Another clinical trial revealed that intravenous acetaminophen has acceptable analgesic effects on the post-cesarean section pain when combined with other analgesic medications. One study revealed that administration of intravenous acetaminophen compared to placebo before hysterectomy decreased consumption of morphine via patient-controlled analgesia pump and decreased the side effects. Similarly, another study revealed that the infusion of intravenous acetaminophen vs. placebo after orthopedic surgery decreased the consumption of morphine after the surgery. A clinical trial revealed intravenous acetaminophen provided a level of analgesia comparable to intravenous morphine in isolated limb trauma, while causing less side effects than morphine.It appears that intravenous acetaminophen has good analgesic effects for visceral, traumatic and postoperative pains compare with intravenous morphine.

    2011-06-01

    Full Text Available Human immunoglobulin is the most used blood product in the clinical practice. Immunoglobulin applications have increased quickly since the elucidation of its immunomodulatory and antiinflammatory properties which turned this blood product into a precious tool in the treatment of numerous diseases that present with humoral immune deficiency or that cause immune system dysfunction. Currently, the approved indications for Ig are: primary immunodeficiencies, secondary immunodeficiencies (multiple myeloma or chronic lymphoid leukemia, Kawasaki syndrome, immune thrombocytopenic purpura, Guillain Barré syndrome, graft-versus-host disease following bone marrow transplantation and repeat infections in HIV children. On the other hand, there are numerous "off-label" indications of immunoglobulin, which represent 20-60% of all clinical applications of this drug. It is important to study all these indications and, above all, the scientific evidence for its use, in order to provide patients with a new therapeutic option without burdening the health system. This review results from a wide selection of papers identified in the Pubmed and Lilacs scientific electronic databases. A group of descriptors were used from human immunoglobulin to the names of each disease that immunoglobulin is clinically applied. Our main objective is to list the numerous indications of immunoglobulin, both authorized and "off-label" and to analyze these indications in the light of the most recent scientific evidence.

  4. Oral versus intravenous methylprednisolone for the treatment of multiple sclerosis relapses: A meta-analysis of randomized controlled trials.

    Full Text Available Intravenous glucocorticoids are recommended for multiple sclerosis (MS. However, they can be inconvenient and expensive. Due to their convenience and low cost, oral glucocorticoids may be an alternative treatment. Recently, several studies have shown that there is no difference in efficacy and safety between oral methylprednisolone (oMP and intravenous methylprednisolone (ivMP.We sought to assess the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses in this meta-analysis.Randomized controlled trials (RCTs evaluating the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses were searched in PubMed, Cochrane Library, Medline, EMBASE and China Biology Medicine until October 25, 2016, without language restrictions. The proportion of patients who had improved by day 28 was chosen as the efficacy outcome. We chose the risk ratio (RR to analyze each trial with the 95% confidence interval (95% CI. We also used the fixed-effects model (Mantel-Haenszel approach to calculate the pooled relative effect estimates.A total of 5 trials were identified, which included 369 patients. The results of our meta-analysis revealed that no significant difference existed in relapse improvement at day 28 between oMP and ivMP (RR 0.96, 95% CI 0.84 to 1.10. No evidence of heterogeneity existed among the trials (P = 0.45, I2 = 0%. Both treatments were equally safe and well tolerated except that insomnia was more likely to occur in the oMP group compared to the ivMP group.Our meta-analysis reveals strong evidence that oMP is not inferior to ivMP in increasing the proportion of patients experiencing clinical improvement at day 28. In addition, both routes of administration are equally well tolerated and safe. These findings suggest that we may be able to replace ivMP with oMP to treat MS relapses.

  5. Treatment of Lead Poisoning: A Comparison between the Effects of Sodium Calciumedetate and Penicillamine Administered Orally and Intravenously1

    1967-01-01

    In 16 workers with lead poisoning of varying degrees, a comparison was made between the therapeutic efficacy of sodium calciumedetate (Ca-EDTA) and penicillamine (PCA), administered intravenously and orally. The question of comparable dosages of ligands, forming metal complexes in different ways, is discussed. With the dosages given, intravenous Ca-EDTA promoted the greatest output of lead in the urine, followed by intravenous and oral PCA. These three agents also had a very satisfactory effect on the output δ-aminolaevulinic acid (ALA) in urine. Oral Ca-EDTA was found to be greatly inferior in both these respects. In order to study the absorption of the agents and the renal excretion of the formed lead complexes, the urine was collected quantitatively and fractionated in consecutive 4-hour periods, after which the lead excretion during each period was determined. It was found that the oral absorption of PCA was rapid and quantitatively great, whereas the oral absorption of Ca-EDTA was very slow and quantitatively small. The possible resorption of ligand-lead complexes is discussed and indications were found of resorption of the Ca-EDTA-lead complex but not of the PCA-lead complex. The renal excretion of the different ligand-lead complexes was very effective and reached its maximal level within four hours. However, in some subjects excretion of the Ca-EDTA-lead complex showed some delay. An investigation, in four subjects, of a blocking effect of probenecid on the renal excretion of PCA and/or PCA-lead complexes gave no conclusive results. It is concluded that oral PCA is satisfactory in most cases of lead poisoning. However, in more severe cases intravenous treatment is preferable. Which agent should be chosen, Ca-EDTA or PCA, appears to be unimportant as both are quite satisfactory from the point of view of treatment, but it seems that Ca-EDTA may cause more serious side-effects. Oral Ca-EDTA is quite unsatisfactory and there is good evidence to indicate that

    A 3-year-old boy developed left-sided convergent strabismus one week after upper respiratory infection. All examinations, including analysis of cerebrospinal fluid, a tensilon test, and brain MRI, were negative. He was diagnosed with idiopathic sixth nerve palsy. His symptom resolved gradually with vitamin B12, and remitted completely three months after onset. At the age of 6 years, he experienced recurrence of left-sided sixth nerve palsy. After vitamin B12 failed, his symptom responded markedly to intravenous steroid pulse therapy starting on day 26 after relapse. He has been symptom-free for three years since the second remission. Steroid therapy might be effective, and should be considered in children with idiopathic sixth nerve palsy who do not show spontaneous remission.

    AbstractBackgroundSevere malaria is a medical emergency with high mortality. Prompt achievement of therapeutic concentrations of highly effective anti-malarial drugs reduces the risk of death. The aim of this study was to assess the pharmacokinetics and pharmacodynamics of intravenous artesunate in Ugandan adults with severe malaria.MethodsFourteen adults with severe falciparum malaria requiring parenteral therapy were treated with 2.4 mg\\/kg intravenous artesunate. Blood samples were collected after the initial dose and plasma concentrations of artesunate and dihydroartemisinin measured by solid-phase extraction and liquid chromatography-tandem mass spectrometry. The study was approved by the Makerere University Faculty of Medicine Research and Ethics Committee (Ref2010-015) and Uganda National Council of Science and Technology (HS605) and registered with ClinicalTrials.gov (NCT01122134).ResultsAll study participants achieved prompt resolution of symptoms and complete parasite clearance with median (range) parasite clearance time of 17 (8–24) hours. Median (range) maximal artesunate concentration (Cmax) was 3260 (1020–164000) ng\\/mL, terminal elimination half-life (T1\\/2) was 0.25 (0.1-1.8) hours and total artesunate exposure (AUC) was 727 (290–111256) ng·h\\/mL. Median (range) dihydroartemisinin Cmax was 3140 (1670–9530) ng\\/mL, with Tmax of 0.14 (0.6 – 6.07) hours and T1\\/2 of 1.31 (0.8–2.8) hours. Dihydroartemisinin AUC was 3492 (2183–6338) ng·h\\/mL. None of the participants reported adverse events.ConclusionsPlasma concentrations of artesunate and dihydroartemisinin were achieved rapidly with rapid and complete symptom resolution and parasite clearance with no adverse events.

  9. Buccal, intranasal or intravenous lorazepam for the treatment of acute convulsions in children in Malawi: An open randomized trial

    Samantha Lissauer

    2015-09-01

    Conclusions: Intravenous lorazepam effectively treats most childhood seizures in this setting. Intranasal and buccal routes are less effective but may be useful in pre-hospital care or when intravenous access cannot be obtained. Further studies comparing intranasal lorazepam to other benzodiazepines, or alternative doses by a non-intravenous route are warranted.

    No previous clinical trial has been conducted for patients with neuroblastoma associated opsoclonus myoclonus ataxia syndrome (OMA), and current treatment is based on case reports. To evaluate the OMA response to prednisone and risk-adapted chemotherapy and determine if the addition of intravenous gammaglobulin (IVIG) further improves response, the Children's Oncology Group designed a randomized therapeutic trial. Eligible subjects were randomized to receive twelve cycles of IVIG (IVIG+) or no IVIG (NO-IVIG) in addition to prednisone and neuroblastoma risk-adapted chemotherapy. All low-risk patients were treated with cyclophosphamide. The severity of OMA symptoms was evaluated at 2, 6, and 12 months using a scale developed by Mitchell and Pike and baseline versus best response scores were compared. A single patient who did not undergo neurologic assessment was excluded from OMA response analysis. This study is registered with Clinical Trials.gov (identifier NCT00033293). Of the 53 patients enrolled in the study, 62% (33/53) were female. There were 44 low-risk, 7 intermediate-risk, and 2 high-risk neuroblastoma patients. Twenty-six subjects were randomized to receive IVIG+ and 27 were randomized to NO-IVIG. The neuroblastoma 3-year event-free survival (95% confidence interval (CI)) was 94.1% (87.3%, 100%) and overall survival was 98.0% (94.1%, 100%). Significantly higher rates of OMA response were observed in patients randomized to IVIG+ compared to NO-IVIG [21/26=80.8% for IVIG+; 11/27=40.7% for NO-IVIG (odds ratio=6.1; 95% CI: (1.5, 25.9), p=0.0029)]. For the majority of patients, the IVIG+ OMA regimen combined with cytoxan or other risk-based chemotherapy was well tolerated, although there was one toxic death in a high-risk subject. This is the only randomized prospective therapeutic clinical trial in children with neuroblastoma-associated OMA. The addition of IVIG to prednisone and risk-adapted chemotherapy significantly improves OMA response rate. IVIG

    Objectives: To determine whether coadjuvant antineoplastic treatment can influence the number and size of bone exposures among patients with intravenous bisphosphonate-related osteonecrosis of the jaws (iBRONJ), and to analyze the buccodental condition of these patients. Material and methods: The study sample comprised 67 patients with iBRONJ, 53 patients without iBRONJ receiving treatment with intravenous bisphosphonates, and 36 healthy subjects. In all three groups, measurements were made of the CAO index and of resting whole saliva and stimulated whole saliva. In the patients with iBRONJ, the size (cm) and number of bone exposures were recorded. The data obtained were subjected to analysis of variance (ANOVA), the Mann-Whitney U-test, and multivariate logistic regression analysis. Results: A total of 57.6% of the patients presented single bone exposure, 25.4% presented two, and 17% more than two exposures. The mean exposure size was 2.3±1.9 cm. Neither the bivariate analysis nor the multivariate multiple regression analysis found coadjuvant antineoplastic treatment to exert a statistically significant effect upon the number and size of bone exposures. On the other hand, there were statistically significant differences among the three study groups in relation to the CAO index (p=0.02) and the number of missing teeth (p=0.00). The resting whole saliva and stimulated whole saliva levels were similar in the three groups, though the patients with osteonecrosis of the jaws showed comparatively lower SWS levels. Conclusions: Coadjuvant antineoplastic treatment alone appears to exert no influence upon the size and number of bone exposures in iBRONJ. The patients with this disease show a higher CAO index and a larger number of missing teeth. Key words:Osteonecrosis of the jaws, bisphosphonates, bone exposure, CAO index, resting whole saliva, stimulated whole saliva. PMID:23229272

    Solithromycin, a novel macrolide antibiotic with both intravenous and oral formulations dosed once daily, has completed 2 global phase 3 trials for treatment of community-acquired bacterial pneumonia. A total of 863 adults with community-acquired bacterial pneumonia (Pneumonia Outcomes Research Team [PORT] class II-IV) were randomized 1:1 to receive either intravenous-to-oral solithromycin or moxifloxacin for 7 once-daily doses. All patients received 400 mg intravenously on day 1 and were permitted to switch to oral dosing when clinically indicated. The primary objective was to demonstrate noninferiority (10% margin) of solithromycin to moxifloxacin in achievement of early clinical response (ECR) assessed 3 days after first dose in the intent-to-treat (ITT) population. Secondary endpoints included demonstrating noninferiority in ECR in the microbiological ITT population (micro-ITT) and determination of investigator-assessed success rates at the short-term follow-up (SFU) visit 5-10 days posttherapy. In the ITT population, 79.3% of solithromycin patients and 79.7% of moxifloxacin patients achieved ECR (treatment difference, -0.46; 95% confidence interval [CI], -6.1 to 5.2). In the micro-ITT population, 80.3% of solithromycin patients and 79.1% of moxifloxacin patients achieved ECR (treatment difference, 1.26; 95% CI, -8.1 to 10.6). In the ITT population, 84.6% of solithromycin patients and 88.6% of moxifloxacin patients achieved clinical success at SFU based on investigator assessment. Mostly mild/moderate infusion events led to higher incidence of adverse events overall in the solithromycin group. Other adverse events were comparable between treatment groups. Intravenous-to-oral solithromycin was noninferior to intravenous-to-oral moxifloxacin. Solithromycin has potential to provide an intravenous and oral option for monotherapy for community-acquired bacterial pneumonia. NCT01968733. © The Author 2016.

    Full Text Available Background: Both nifekalant hydrochloride (NIF, a selective IKr blocker, and intravenous amiodarone (AMD, a multi-channel (including IKr blocking blocker, have been reported to be efficacious for refractory arrhythmias. However, the optimal use of those antiarrhythmic drugs for refractory arrhythmia with severe heart failure has not been established. Intravenous AMD might be effective for arrhythmias refractory to NIF in patients with severe heart failure. Here, we report that intravenous amiodarone was effective in the treatment of nifekalant-resistant in a group of arrhythmia patients with severe heart failure. Methods: Eleven severe heart failure patients who had received intravenous AMD for treatment of NIF-resistant arrhythmias were included in this study, and retrospective analysis was performed. Clinical efficacy (terminative and preventive effects on arrhythmia of intravenous AMD was evaluated. Results: All cases were emergent cases and had depressed left ventricular ejection fraction (30 ± 13%. Clinical arrhythmias were ventricular fibrillation (VF in four patients, ventricular tachycardia (VT in six patients, and atrial fibrillation (AF in one patient. NIF was administered to all patients by intravenous injection. After administration of NIF, VT/VF/AF was terminated in seven of the 10 patients, but a preventive effect was not obtained in any of the patients (NIF-resistance. Intravenous AMD (maintenance dose: 484 ± 166 mg/day was effective both in termination (80% and in prevention (80% of VT/VF events in those patients. It was also effective in termination (80% and prevention (60% of AF events refractory to NIF. During continuous AMD administration, no significant adverse effects or proarrhythmic effects were observed in any of the patients. Five patients died within one month, but there was no arrhythmic deaths. Conclusions: Intravenous AMD was effective in NIF-resistant lethal arrhythmias and was relatively safe in emergent cases

    Although artemesinin derivatives are promising for the treatment of severe Plasmodium falciparum malaria, intravenous quinine remains the most affordable treatment. However, administration of intravenous quinine is often not feasible in rural areas in Africa because of the lack of simple equipment or trained staff. We compared the efficacy and safety of intrarectal quinine with those of intravenous quinine in the treatment of childhood cerebral malaria. In a randomized, double-blind clinical trial at Mulago Hospital (Kampala, Uganda), Uganda's national referral hospital, we studied 110 children aged 6 months to 5 years who had cerebral malaria. Patients were randomized to receive either intrarectal or intravenous quinine. Main outcome measures included parasite clearance time, fever clearance time, coma recovery time, time to sit unsupported, time to begin oral intake, time until oral quinine was tolerated, and death. Overall, there was no difference in the clinical and parasitological outcomes between the 2 groups (data are mean+/-standard deviation, intrarectal quinine group vs. intravenous quinine group): coma recovery time, 19.4+/-18.1 h versus 17.0+/-12.1 h; fever clearance time, 26.7+/-16.1 h versus 29.9+/-18.1 h; and parasite clearance time, 43.2+/-14.2 h versus 41.9+/-15.2 h. Mortality was similar in both groups; 4 of 56 patients in the intrarectal quinine group died, and 5 of 54 patients in the intravenous quinine group died (odds ratio, 1.3; 95% confidence interval, 0.3-5.2). Intrarectal quinine was well tolerated, and no major immediate adverse events occurred. Intrarectal quinine is efficacious and could be used as an alternative in the treatment of childhood cerebral malaria, especially in situations in which intravenous therapy is not feasible.

    Background Induced hypothermia is a promising neuroprotective therapy. We studied the feasibility and safety of hypothermia and thrombolysis after acute ischemic stroke. Methods ICTuS-L was a randomized, multi-center trial of hypothermia and intravenous t-PA in patients treated within 6 hours after ischemic stroke. Enrollment was stratified to the treatment time windows 0–3 and 3–6 hours. Patients presenting within 3 hours of symptom onset received standard dose intravenous alteplase (IV tPA) and were randomized to undergo 24 hours of endovascular cooling to 33°C followed by 12 hours of controlled re-warming or normothermia treatment. Patients presenting between 3 and 6 hours were randomized twice: to receive t-PA or not and to receive hypothermia or not. Results In total, 59 patients were enrolled. One patient was enrolled but not treated when pneumonia was discovered just prior to treatment. All 44 patients enrolled within 3 hours and 4 of 14 patients enrolled between 3–6 hours received t-PA. Overall, 28 patients randomized to receive hypothermia (HY) and 30 to normothermia (NT). Baseline demographics and risk factors were similar between groups. Mean age was 65.5±12.1 years and baseline NIHSS was 14.0±5.0; 32 (55%) were male. Cooling was achieved in all patients except 2 in whom there were technical difficulties. The median time to target temperature after catheter placement was 67min (Q1 57.3 –Q3 99.4). At 3 months, 18% of patients treated with HY had a modified Rankin Scale (mRS) of 0 or 1, versus 24% in the NT groups (NS). Symptomatic intracranial hemorrhage occurred in 4 patients (68), all were treated with tPA less than 3 hours (1 received HY). Six patients in the HY and 5 in the NT groups died within 90 days (NS). Pneumonia occurred in 14 patients in the HY and in 3 of the NT groups (p=0.001). The pneumonia rate did not significantly adversely affect 3 month mRS (p=0.32). Conclusion This study demonstrates the feasibility and preliminary safety

    In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

Since approval in 1996, tPA remains the only drug treatment for acute ischemic stroke approved by the US Food and Drug Administration. Over the years, an abundance of research and clinical data has supported the safe and efficacious use of intravenous tPA in all eligible patients. Despite such supporting data, it remains substantially underutilized. Challenges to the utilization of tPA include narrow eligibility and treatment windows, risk of symptomatic intracerebral hemorrhage, perceived lack of efficacy in certain high-risk subgroups, and a limited pool of neurological and stroke expertise in the community. With recent US census data suggesting annual stroke incidence will more than double by 2050, better education and consensus among both the medical and lay public are necessary to optimize the use of tPA for all eligible stroke patients. Ongoing and future research should continue to improve upon the efficacy of tPA through more rapid stroke diagnosis and treatment, refinement of advanced neuroimaging and stroke biomarkers, and successful demonstration of alternative means of reperfusion.

    Preliminary evidence supports the safety and efficacy of subanesthetic ketamine as an experimental antidepressant, although its effects are often not sustained beyond one week. Studies are lacking that have examined the sustained effects of escalating ketamine doses as augmentation in outpatients with treatment-resistant depression. Therefore, the aims of this study were twofold: (1) to assess the safety and antidepressant efficacy of two-step, repeated-dose ketamine augmentation and (2) to assess the duration of ketamine's antidepressant efficacy as augmentation to ongoing antidepressant pharmacotherapy for 3 months after the final infusion. Fourteen patients with treatment-resistant depression were eligible to receive augmentation with six open-label intravenous ketamine infusions over 3 weeks. For the first three infusions, ketamine was administered at a dose of 0.5 mg/kg over 45 minutes; the dose was increased to 0.75 mg/kg over 45 minutes for the subsequent three infusions. The primary outcome measure was response (as measured on Hamilton Depression Rating Scale-28 items). After the completion of three ketamine infusions, 7.1% (1/14) responded; after all six ketamine infusions, 41.7% (5/12) completers responded and 16.7% (2/12) remitted. Intent-to-treat response and remission rates at the end of the final infusion were 35.7% (5/14) and 14.3% (2/14), respectively. However, all but one responder relapsed within 2 weeks after the final infusion. Repeated, escalating doses of intravenous ketamine augmentation were preliminarily found to be feasible, efficacious and well tolerated. Interaction with concomitant medications and elevated level of treatment resistance are possible factors for non-response.

    Full Text Available Abstract Parenteral artesunate has been shown to be a superior treatment option compared to parenteral quinine in adults and children with severe malaria. Little evidence, however, is available on long-term safety. Recently, cases of late-onset haemolysis after parenteral treatment with artesunate have been reported in European travellers with imported Plasmodium falciparum malaria. Therefore, an extended follow-up of adult patients treated for severe imported malaria was started in August 2011 at the University Medical Center Hamburg-Eppendorf. Until January 2012, three patients with hyperparasitaemia (range: 14-21% were included for analysis. In all three patients, delayed haemolysis was detected in the second week after the first dose of intravenous artesunate. Reticulocyte production index remained inadequately low in the 7 – 14 days following the first dose of artesunate despite rapid parasite clearance. Post-treatment haemolysis after parenteral artesunate may be of clinical relevance in particular in imported severe malaria characterized by high parasite levels. Extended follow-up of at least 30 days including controls of haematological parameters after artesunate treatment seems to be indicated. Further investigations are needed to assess frequency and pathophysiological background of this complication.

    To study the effect of the introduction of a substitution by intravenous Immunoglobulins (Ig IV) at patients with immunoglobulins G (IgG) subclasses deficiency and nasal polyposis. Prospective study concerning five patients with IgG subclasses deficiency and nasal polyposis treated by Ig IV. Rhinologic, otologic and pulmonary symptoms, exacerbations of nasal polyposis, chronic otitis and asthma as well as the number of antibiotics and corticoids treatments were counted during the Ig IV substitution. To study the association between IgIV substitution and the number of exacerbations of nasal polyposis, chronic otitis, asthma and the number of antibiotics and corticoids treatments in patients with IgG subclasses deficiency and nasal polyposis. Five patients with a IgG subclass deficiency and nasal polyposis were substituted. The number of antibiotics and corticoids cures increased at one patient and remained stable at four others. The number of sinus, ear and lung infections as well as the global rhinologic score of symptoms and the endoscopic stage of the nasal polyposis remained stable. In the absence of efficiency of the treatment, this one was interrupted at the end of 6 months for patients n° 1 and n° 3, 24 months for patient n° 4 and 42 months for patient n° 5. The current study failed to highlight clinical improvement in patients wih IgG subclasses deficiency and nasal polyposis treated by Ig IV. A previous study had not allowed to find a link between IgG subclasses deficiency and severity of nasal polyposis, what seems to be confirmed by the absence of improvement brought during the substitution of this deficit in the current study.

    Full Text Available Liver cirrhosis is the 6th leading cause of death in adults aged 15–59 years in high-income countries. For many who progress to cirrhosis, the only prospect for survival is liver transplantation. While there is some indication that mesenchymal stem cells may be useful in reversing established liver fibrosis, there are limitations to their widespread use – namely their rarity, the need for extensive serial passaging and the associated potential for genomic instability and cellular senescence. To this end, we propose the use of allogeneic amnion epithelial cells. This clinical trial will assess the safety of intravenously delivered allogeneic human amnion epithelial cells (hAECs in patients with compensated liver cirrhosis. This will also provide clinical data that will inform phases 2 and 3 clinical trials with the ultimate goal of developing hAECs as a therapeutic option for patients with cirrhosis who are at significant risk of disease progression. We will recruit 12 patients with compensated cirrhosis, based on their hepatic venous pressure gradient, for a dose escalation study. Patients will be closely monitored in the first 24 h post-infusion, then via daily telephone interviews until clinical assessment on day 5. Long term follow up will include standard liver tests, transient elastography and hepatic ultrasound. Ethics approval was obtained from Monash Health for this trial 16052A, “A Pilot Study Evaluating the Safety of Intravenously Administered Human Amnion Epithelial Cells for the Treatment of Liver Fibrosis, A First in Adult Human Study.” The trial will be conducted in accordance to Monash Health Human Ethics guidelines. Outcomes from this study will be disseminated in the form of conference presentations and submission to a peer reviewed journal. This trial has been registered on the Australian and New Zealand Clinical Trials Registry ACTRN12616000437460.

    Background. Mistletoe therapy (MT) is widely used in patient-centered integrative cancer care. The objective of this study was to explore the concepts, procedures, and observations of expert doctors, with a focus on intravenous MT. Method. A qualitative interview study was conducted with 35 highly experienced doctors specialized in integrative and anthroposophic medicine. Structured qualitative content analysis was applied. For triangulation, the results were compared with external evidence that was systematically collected, reviewed, and presented. Results. Doctors perform individualized patient assessments that lead to multimodal treatment approaches. The underlying goal is to help patients to live with and overcome disease. Mistletoe infusions are a means of accomplishing this goal. They are applied to stabilize disease, achieve responsiveness, induce fever, improve quality of life, and improve the tolerability of conventional cancer treatments. The doctors reported long-term disease stability and improvements in patients' general condition, vitality, strength, thermal comfort, appetite, sleep, pain from bone metastases, dyspnea in pulmonary lymphangitis carcinomatosa, fatigue, and cachexia; chemotherapy was better tolerated. Also patients' emotional and mental condition was reported to have improved. Conclusion. Individualized integrative cancer treatment including MT aims to help cancer patients to live well with their disease. Further research should investigate the reported observations.

    Aluminium phosphide (AlP) is used to protect stored grains from rodents. It produces phosphine gas (PH3), a mitochondrial poison thought to cause toxicity by blocking the cytochrome c oxidase enzyme and inhibiting oxidative phosphorylation, which results in cell death. AlP poisoning has a high mortality rate among humans due to the rapid onset of cardiogenic shock and metabolic acidosis, despite aggressive treatment. We report a 21-year-old male who was referred to the Afzalipour Hospital, Kerman, Iran, in 2015 after having intentionally ingested a 3 g AlP tablet. He was successfully treated with crystalloid fluids, vasopressors, sodium bicarbonate, digoxin, glucagon and antioxidant agents and was discharged from the hospital six days after admission in good clinical condition. For the treatment of AlP poisoning, the combination of glucagon and digoxin with antioxidant agents should be considered. However, evaluation of further cases is necessary to optimise treatment protocols.

    To investigate the efficacy and safety of intravenous cervus and cucumis polypeptides for treating avascular necrosis of the femoral head (ANFH) in regard to pain and hip function in a randomized clinical trial. A total of 96 subjects with ANFH who were recruited at the Orthopaedic Hospital Affiliated with Hebei United University and Qian Hai Femoral Head Hospital of Beijing were assigned by lottery to an intervention group (n = 48) or a control group (n = 48). All subjects underwent physical therapy and rehabilitation exercises. In addition, subjects in the intervention group were given intravenous infusions of cervus and cucumis polypeptides. Visual analogue scale (VAS), Harris hip score, and radiography or magnetic resonance imaging were applied to assess all subjects at the beginning of treatment and 3, 6, and 9 months afterward. All the subjects were followed up for 2 years. At the beginning of treatment, there were no statistically significant differences between the two groups in terms of the general condition of patients or the VAS and Harris hip scores (all P > 0.05). At 3, 6, and 9 months after treatment, however, the VAS score decreased and the Harris hip score increased in all patients, with the improvement of intervention group significantly greater than that of the control group (P 0.05). Intravenous infusion of cervus and cucumis polypeptides relieved pain and improved hip function of subjects with ANFH. Thus, the intravenous infusion of cervus and cucumis polypeptides was a safe, effective treatment for ANFH.

    Although intravenous immunoglobulin (IVIg) is widely used for replacement therapy in immunodeficiencies and to treat autoimmune and inflammatory diseases, its mechanisms of action are not fully understood. Examination of immunoglobulin (Ig) receptors, including the Fc-gamma receptors (FCγRs) and the neonatal Fc receptor, have revealed genetic variations that are linked to autoimmune diseases and to the efficacy of IVIg treatment. However, the beneficial effect of IVIg encompasses multiple mechanisms of action. One of these is scavenging of activated complement fragments, such as C3a, C5a, C3b and C4b, by infused Ig molecules. This interaction prevents binding of complement fragments to their receptors on target cells, thus attenuating the immune damage. Additionally, anti-inflammatory effects may be facilitated by IgA via specific receptors and/or complement scavenging. Glycosylation of both the Fc- and Fab-fragments has also been implicated in the anti-inflammatory action of IVIg. Although there is evidence to support a role for sialylated IgG glycovariants in mediating the effect of IVIg, evidence from animal models of inflammatory disease suggest that sialylation may not be a critical factor. However, an increase in IgG glycosylation has been observed following IVIg treatment in Guillain-Barré syndrome patients, and this has been associated with improved clinical outcomes. © 2014 British Society for Immunology.

    Full Text Available BACKGROUND: Low Molecular Weight Heparins (LMWH are at least as effective antithrombotic drugs as Unfractionated Heparin (UFH. However, it is still unclear whether the safety profiles of LMWH and UFH differ. We performed a systematic review to compare the bleeding risk of fixed dose subcutaneous LMWH and adjusted dose UFH for treatment of venous thromboembolism (VTE or acute coronary syndromes (ACS. Major bleeding was the primary end point. METHODS: Electronic databases (MEDLINE, EMBASE, and the Cochrane Library were searched up to May 2010 with no language restrictions. Randomized controlled trials in which subcutaneous LMWH were compared to intravenous UFH for the treatment of acute thrombotic events were selected. Two reviewers independently screened studies and extracted data on study design, study quality, incidence of major bleeding, patients' characteristics, type, dose and number of daily administrations of LMWH, co-treatments, study end points and efficacy outcome. Pooled odds ratios (OR and 95% confidence intervals (CI were calculated using the random effects model. RESULTS: Twenty-seven studies were included. A total of 14,002 patients received UFH and 14,635 patients LMWH. Overall, no difference in major bleeding was observed between LMWH patients and UFH (OR = 0.79, 95% CI 0.60-1.04. In patients with VTE LMWH appeared safer than UFH, (OR = 0.68, 95% CI 0.47-1.00. CONCLUSION: The results of our systematic review suggest that the use of LMWH in the treatment of VTE might be associated with a reduction in major bleeding compared with UFH. The choice of which heparin to use to minimize bleeding risk must be based on the single patient, taking into account the bleeding profile of different heparins in different settings.

    Several studies have shown how cytostatics may cause hypofunction of salivary glands but failed to elucidate any potentially related side effects. Keeping in mind the sialochemical assistance and the role of saliva on the homeostasis of the stomatognathic system, the aim of this study was to establish potential gland disorders in patients submitted to 5- Fluorouracil (5-Fu) and Leucovorin calcium (LV) as well as their correlation with certain oral health disorders that diminish the quality of life. the focus of this research was observational and longitudinal. Twenty-five patients diagnosed with colon cancer at an initial, intermediate and late phase submitted to specifically devised therapy were assessed. Clinical history, oral health indexes and basal or stimulated saliva samples were recorded. Basal and stimulated flow dropped in the intermediate stage. Stimulated saliva pH decreased during treatment. On basal saliva, urea, sodium and potassium rose during the intermediate phase. Löe and Silness rates as well as simplified bleeding increased during therapy but reverted by the end of the treatment. Depth index of the vestibular gingival sulcus rose during the intermediate phase but did not return. This treatment caused functional salivary gland disorders as evidenced by basal and stimulated hyposialia, and acidification of stimulated saliva pH during the intermediate phase. Increase in basal urea may be due to proteic catabolism arising from plasma or glands. Variation in Na+ and K+ of basal saliva concentrates might be assumed as a possible duct disorder. Recovery of bleeding and Löe and Silness rates may point to a transient inflammatory effect associated to a decrease in salivary flow. Increase in the depth rates of the periodontal vestibular sulcus could be correlated with a higher risk of periodontal disease.

Puerperal anemia can impair postpartum maternal and neonatal well-being. Objective: To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III-hydroxide polymaltose. Methodology: A randomized controlled study in which postpartum women with moderate iron-deficiency anemia were randomized into treatment with either a single total-dose intravenous iron dextran or with daily single doses of oral iron(III-hydroxide polymaltose tablets for 6 weeks. Effects on hemoglobin concentration using either method were compared at 6 weeks postpartum. Analysis was per protocol using SPSS version 17 for windows. P-values ≤0.05 were considered significant. Results: Two hundred eighty-four women were recruited for the study: 142 women received single total dose intravenous infusion of iron dextran while 142 received daily oral iron(III-hydroxide polymaltose tablets. Approximately 84.0% (237/282 completed the study and were analyzed including 81% (115/142 of those randomized to injectable iron therapy compared to 85.9% (122/142 of those randomized to oral treatment.

    Pregnancy-associated malaria (PAM) is an important cause of maternal and neonatal suffering. It is caused by Plasmodium falciparum capable of inhabiting the placenta through expression of particular variant surface antigens (VSA) with affinity for proteoglycans such as chondroitin sulfate A....... Protective immunity to PAM develops following exposure to parasites inhabiting the placenta, and primigravidae are therefore particularly susceptible to PAM. The adverse consequences of PAM in primigravidae are preventable by intermittent preventive treatment (IPTp), where women are given antimalarials...... at specified intervals during pregnancy, but this may interfere with acquisition of protective PAM immunity. We found that Kenyan primigravidae receiving sulfadoxine-pyrimethamine IPTp had significantly lower levels of immunoglobulin G (IgG) with specificity for the type of parasite-encoded VSA-called VSA(PAM...

    Injectable opioids are an interesting option for people who inject drugs (PWID) that do not respond to oral Opioid Maintenance Treatment (OMT). To date, intravenous (IV) buprenorphine - a safer drug than full-opioid agonists in terms of overdose risk - has never been tested in a clinical trial on opioid dependence. We designed a survey to better understand the profile of PWID eligible for IV buprenorphine, and their willingness to receive it. This cross-sectional community-based national survey was conducted through face-to-face interviews (in low-threshold and addiction care services) and online questionnaires (on https://psychoactif.org and other websites). Among the 557 participants, we selected those who were eligible for IV buprenorphine treatment (history of oral OMT, regular opioid injection) (n = 371). We used regression models to study factors associated with willingness to receive IV buprenorphine treatment among those with data on willingness (n = 353). In those who were willing (n = 294), we subsequently studied their willingness to receive daily supervised IV buprenorphine treatment. Among the selected 353 participants, 59% mainly injected buprenorphine, 15% heroin, 16% morphine sulfate and 10% other opioids. Eighty-three percent of the sample reported willingness to receive IV buprenorphine treatment. Factors associated with willingness were: more than 5 injection-related complications, regular buprenorphine injection, no lifetime overdose, and completion of the questionnaire online. Factors associated with unwillingness to receive daily supervised treatment were younger age (OR[IC95%]=1.04[1.01; 1.07]) and stable housing (OR[IC95%]=0.61[0.37;1.01]) while regular heroin injectors were more willing to receive daily supervision (OR[IC95%]=2.94 [1.42; 6.10]). PWID were very willing to receive intravenous buprenorphine as a treatment, especially those with multiple injection-related complications. In addition, our findings show that IV buprenorphine

Analysis was carried out from a National Health Service (NHS perspective and also from a patient perspective. Total cost treatment reflects the cost of drugs, the cost of all resources expended in patient management such as the cost of disposables for each infusion, the monitoring costs during infusion (salaries of personnel, other hospital expenses, the cost for management of adverse events, the productivity loss, and the traveling cost for patients.Results: In the case of outpatients, the mean total cost per patient in the FCM arm was €198.6, in the IS arm €627.7, and in the LMWID arm, €510.5. For inpatients the mean total cost was estimated at €189.2 for FCM while it was €419.9 and €228.8 for IS and LMWID, respectively. Budget impact analysis for a typical Greek hospital with 100 patients revealed that the total cost of FCM (inpatients analysis was 113% and 15.4% lower against their comparators. In an

    Granulomatous lymphocytic interstitial lung disease, or GLILD, is an uncommon condition associated with common variable immunodeficiency (CVID). We present an interesting case of an 18-year-old woman with Kabuki syndrome and CVID who was seen in our clinic for an abnormal chest CT scan. She was subsequently diagnosed with GLILD. There are no established guidelines for the treatment of GLILD in CVID. Immune globulin replacement therapy is the main treatment for CVID and higher doses of intravenous immunoglobulin (IVIG) may prevent the progression of chronic lung disease. Patients with CVID and GLILD are at increased risk for malignancy and their prognosis is worse compared to patients with CVID without GLILD.

    Host genetic factors, especially genes of the immune system, are thought to contribute to the racial differences in response rates to therapy for hepatitis C virus (HCV) infection. The aim of the present investigation was to determine whether immunoglobulin gamma heavy chain marker (GM) and kappa light chain marker (KM) -were associated with sustained viral response (SVR) in patients treated with peginterferon-α-2a and ribavirin. DNA samples from 319 subjects with genotype-1 HCV infections were allotyped for alleles at four GM loci: GM3/GM17, GM23+/GM23-, GM5/GM21, GM6+/GM6- and the KM locus: KM1/KM3, using molecular methods. Noncarriage of KM1 allele, i.e., KM3 homozygosity, was associated with higher SVR in African Americans (odds ratio = 2.50, 95% confidence interval = 1.12-5.60). Consistent with this finding, the HCV RNA level in KM1 noncarriers was significantly (p = 0.013) lower than in carriers of this allele. Thus, the KM3 allele may be a marker for higher SVR in African Americans. Copyright © 2011 American Society for Histocompatibility and Immunogenetics. Published by Elsevier Inc. All rights reserved.

  8. Suppression of pokeweed mitogen-stimulated immunoglobulin production in patients with rheumatoid arthritis after treatment with total lymphoid irradiation

    Patients with intractable rheumatoid arthritis (RA) were treated with total lymphoid irradiation (TLI, 200 rad). The authors previously reported long-lasting clinical improvement in this group associated with a persistent decrease in circulating Leu-3 (helper subset) T cells and marked impairment of in vitro lymphocyte function. In the present experiments, they studied the mechanisms underlying the decrease in pokeweed mitogen stimulated immunoglobulin (Ig) secretion observed after TLI. Peripheral blood mononuclear cells (PBL) from TLI-treated patients produced 10-fold less Ig (both IgM and IgG) in response to pokeweed mitogen than before radiotherapy. This decrease in Ig production was associated with the presence of suppressor cells in co-culture studies. By using responder cells obtained from normal individuals (allogeneic system), PBL from eight of 12 patients after TLI suppressed Ig synthesis by more than 50%. In contrast, PBL from the same patients before TLI failed to suppress Ig synthesis. PBL with suppressive activity contained suppressor T cells, and the latter cells bore the Leu-2 surface antigen. In 50% of the patients studied suppressor cells were also found in the non-T fraction and were adherent to plastic. Interestingly, the Leu-2 + cells from TLI-treated patients were no more potent on a cell per cell basis than purified Leu-2 + cells obtained before TLI. Additional experiments suggested that the suppression mediated by T cells after TLI is related to the increased ratio of Leu-2 to Leu-3 cells observed after radiotherapy

    Adult Holstein cows were injected with an antiserum against Campylobacter jejuni and immunoglobulin activities in vitro were determined in blood and milk several weeks after injection. The immunoactivity of immunoglobulins in milk was measured by an ELISA after different temperature-time treatments (60-91°C and 4-3600 s) at laboratory and pilot-plant scales. Kinetic and thermodynamic parameters were determined. An increase in immunoglobulin activity in milk was detected several days after injection. Optical densities increased by three- to seven-fold in this period. The activity started to decay 4-5 weeks after injection. Immunoglobulins maintained most of their in vitro activity under pasteurisation conditions (72°C and 15 s) and were denatured following first-order kinetics. The injection protocol applied allows milk with specific immunoglobulins against Campylobacter jejuni to be obtained. Traditional pasteurisation did not reduce this activity. © 2013 Society of Chemical Industry.

    Full Text Available INTRODUCTION: This study aimed to discuss the results of the intravenous thrombolytic treatment (IV-tPA to acute ischemic stroke patients, in the light of the literature. METHODS: We performed our study with forty acute ischemic stroke patients who were receiving the IV-tPA in the intensive care unit of our neurology clinic between 2011 and 2015.. The demographic, clinical and radiological data were collected retrospectively. The intracranial hemorrhage detected within 3 months after discharge and neurological status at the end of the 3rd month were evaluated by using modified Rankin scale (MRS and National Institutes of Health Stroke Scale (NIHSS scores. The symptom-to-needle time, Alberta stroke programe early computed tomography score (ASPECT and initial and follow-up scores of NIHSS were analyzed. RESULTS: Fifteen patients were female, twenty-five were male, and the mean age was 66.45±10.56. The initial mean NIHSS score was 13±4.33, whereas it was 4,10±3,37at 3rd month. The initial mean ASPECT score was 8.23±1.20. Symptomatic intracranial hemorrhage was detected in 1 patient and asymptomatic intracranial hemorrhage was detected in 6. The mean symptom-to-needle time was 139,0±48,1 minutes. The neurological disability of 13 patients ( %32.5 were fully recovered at the end of the 3rd month, while 7 patients were died. (% 17,5 The initial NIHSS and ASPECT scores were significantly different between group of patients with a MRS score between 0-2 and between 3-6 (p=0.03 and p=0.006; respectively, while the symptom-to-needle time was not different (p=0.79. DISCUSSION AND CONCLUSION: The results of the current study are in accordance with previous studies in the literature. These results have shown that the IV-tPA treatment is efficient and safe treatment modality in acute ischemic stroke, and reduces disability at the end of the 3rd month.

    Intravenous rituximab is the standard of care in B-cell non-Hodgkin lymphoma, and is administered over 1·5-6 h. A subcutaneous formulation could reduce patients' treatment burden and improve resource utilisation in health care. We aimed to show the pharmacokinetic non-inferiority of subcutaneous rituximab to intravenous rituximab in follicular lymphoma and to provide efficacy and safety data. SABRINA is a two-stage, randomised, open-label phase 3 study at 113 centres in 30 countries. Eligible patients were aged 18 years or older and had histologically confirmed, previously untreated, CD20-positive grade 1, 2, or 3a follicular lymphoma; Eastern Co-operative Oncology Group performance statuses of 0-2; bidimensionally measurable disease (by CT or MRI); life expectancy of 6 months or more; adequate haematological function for 28 days or more; and one or more symptoms requiring treatment according to the Groupe d'Etudes des Lymphomes Folliculaires criteria. Patients were randomly assigned (1:1) by investigators or members of the research team via a dynamic randomisation algorithm to 375 mg/m 2 intravenous rituximab or 1400 mg subcutaneous rituximab, plus chemotherapy (six-to-eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone [CHOP] or eight cycles of cyclophosphamide, vincristine, and prednisone [CVP]), every 3 weeks during induction, then rituximab maintenance every 8 weeks. Randomisation was stratified by selected chemotherapy, Follicular Lymphoma International Prognostic Index, and region. The primary endpoint for stage 2 was overall response (ie, confirmed complete response, unconfirmed complete response, and partial response) at the end of induction. Efficacy analyses were done in the intention-to-treat population. Pooled data from stages 1 and 2 are reported on the basis of the clinical cutoff date of the last patient completing the maintenance phase of the study.

    The results of experimental study which have carried out on 40 outbread dogs were analyzed in this thesis. Modeling of destructive pancreatitis in animals has been achieved via canalicular-hypertensive model by S.A. Shalimov. 4 series of experimental study were made to achieve the targeted goal. The first series 10 dogs without treatment, the second series 10 dogs in which conventional conservative therapy was used for the treatment of acute experimental destructive pancreatitis in animals, the third series 10 dogs that underwent intravenous ozone therapy in the complex together with medication therapy, the forth series the effectiveness of combined administration of intravenous ozone therapy and small doses of direct current in 10 dogs was evaluated. Combined administration of small doses of DC and intravenous ozone therapy in the complex treatment of destructive pancreatitis shows antiphlogistic action, favors accelerated rejection of necrotic tissue, remits inflammatory process as well as encourages regeneration process in pancreas whereby allows to decrease the mortality in experimental animals from 60% to 20%.

    Pooled human immunoglobulins (IGs) are prepared from plasma obtained from healthy donors as a concentrated antibody-containing solution. In addition, high-titer IGs (hyperimmune) against a specific pathogen can be obtained from vaccinated or convalescing donors. Currently, IGs can be used for the treatment of a variety of infections for which no specific therapy exists or that remain difficult to treat. Moreover, the recent pathogen outbreaks for which there is no approved treatment have renewed attention to the role of convalescent plasma and IGs. Areas covered: In this review, a historical perspective of the use of sera and IGs in humans as anti-infective agents (any viral, bacterial, parasitic infection), excluding immunodeficient patients, is presented from early development to the latest clinical studies. A Medline search was conducted to examine the peer-reviewed literature, with no date limits. Expert commentary: Human pooled plasma-derived IG products benefit from the polyclonal response of every individual donor and from the interindividual variability in such response. The trend to increased availability of vaccines for infectious diseases also opens new potential applications of hyperimmune IGs for emerging or re-emerging infectious diseases (e.g.: Ebola, Zika, Dengue), for the prevention and treatment in the general population, healthcare personnel and caregivers.

    Exchange transfusion and phototherapy have traditionally been used to treat jaundice and avoid the associated neurological complications. Because of the risks and burdens of exchange transfusion, intravenous immunoglobulin (IVIg) has been suggested as an alternative therapy for alloimmune hemolytic disease of the newborn (HDN) to reduce the need for exchange transfusion. To assess the effect and complications of IVIg in newborn infants with alloimmune HDN on the need for and number of exchange transfusions. We performed electronic searches of CENTRAL, PubMed, Embase (Ovid), Web of Science, CINAHL (EBSCOhost), Academic Search Premier, and the trial registers ClinicalTrials.gov and controlled-trials.com in May 2017. We also searched reference lists of included and excluded trials and relevant reviews for further relevant studies. We considered all randomized and quasi-randomized controlled trials of IVIg in the treatment of alloimmune HDN. Trials must have used predefined criteria for the use of IVIg and exchange transfusion therapy to be included. We used the standard methods of Cochrane and its Neonatal Review Group. We assessed studies for inclusion and two review authors independently assessed quality and extracted data. We discussed any differences of opinion to reach consensus. We contacted investigators for additional or missing information. We calculated risk ratio (RR), risk difference (RD) and number needed to treat for an additional beneficial outcome (NNTB) for categorical outcomes. We calculated mean difference (MD) for continuous variables. We used GRADE criteria to assess the risk of bias for major outcomes and to summarize the level of evidence. Nine studies with 658 infants fulfilled the inclusion criteria. Term and preterm infants with Rh or ABO (or both) incompatibility were included. The use of exchange transfusion decreased significantly in the immunoglobulin treated group (typical RR 0.35, 95% CI 0.25 to 0.49; typical RD -0.22, 95% CI -0.27 to

    2016-01-01

    Cumulative recent evidence from clinical trials, observational studies and case reports has shown that subcutaneous administration of immunoglobulin (SCIg) exerts similar immunomodulatory capacity than intravenous immunoglobulin (IVIg) in autoimmune neurological diseases. Besides the beneficial clinical effects, the profile of safety and autonomy for the patient is higher for SCIg, while it is cost-saving in terms of the health resources used. However, there are still very few approved indications for SCIg and a certain resistance to choose SCIg for other autoimmune conditions even despite patients' interests. Here we present an updated review of the known immunomodulatory mechanisms of action of Ig and the current hypothesis supporting the clinical and immunological advantages of SCIg over IVIg that derive from their specific pharmacokinetic features.

    The approved treatment by the Food and Drug Administration for acute ischemic stroke is intravenous tissue-type plasminogen activator (IV tPA). After IV tPA administration, patients are monitored for adverse events using an American Heart Association/American Stroke Association guideline instituted in 1996. There is limited evidence describing the safest and most efficient method to monitor patients during the first 24 hours after tPA administration. Although the overall rates of adverse events have been reported, the time when patients may be at most risk for an event has not been studied. The purpose of this study was to identify the time of adverse event occurrences in the first 24 hours after IV tPA administration. This was a descriptive, retrospective chart review study of patients admitted to an integrated health system and treated with IV tPA for acute stroke between July 2010 and July 2012. Charts were reviewed for adverse events using the Institute for Healthcare Improvement's Global Trigger Tool for Measuring Adverse Events. Possible chart indicators of adverse events or "triggers" included neurological decline, vital signs elevated above specified parameters, and emergent imaging. Adverse events included episodes of neurological decline, angioedema, allergic reactions, bleeding, and intracerebral hemorrhage (ICH). The timing of each detected event was determined, and descriptive statistics were used for data analysis. Fourteen adverse events (2.8%) were detected in a population of 498 patients. Reactions consisted of allergic reaction (n = 1), angioedema (n = 1), neurological decline without ICH (n = 1), gastrointestinal bleeding (n = 1), bleeding gums (n = 1), and high-risk ICH (n = 9). Thirteen of the 14 adverse events (92.9%) occurred within the first 12 hours after IV tPA administration. Close monitoring during the first 12 hours after IV tPA treatment may be essential. However, close monitoring after 12 hours may not contribute significantly to

    Background Non-steroidal anti-inflammatory drugs are often used as components of multimodal therapy for postoperative pain management, but their use is currently limited by its side effects. The specific objective of this study was to evaluate the efficacy and safety of a new formulation of intravenous (IV) ibuprofen for the management of postoperative pain in a European population. Methods and Findings A total of 206 patients from both abdominal and orthopedic surgery, were randomly assigned in 1:1 ratio to receive 800 mg IV-ibuprofen or placebo every 6 hours; all patients had morphine access through a patient controlled analgesia pump. The primary outcome measure was median morphine consumption within the first 24 hours following surgery. The mean±SEM of morphine requirements was reduced from 29,8±5,25 mg to 14,22±3,23 mg (p = 0,015) and resulted in a decrease in pain at rest (p = 0,02) measured by Visual Analog Scale (VAS) from mean±SEM 3.34±0,35 to 0.86±0.24, and also in pain during movement (p = 0,02) from 4.32±0,36 to 1.90±0,30 in the ibuprofen treatment arm; while in the placebo group VAS score at rest ranged from 4.68±0,40 to 2.12±0,42 and during movement from 5.66±0,42 to 3.38±0,44. Similar treatment-emergent adverse events occurred across both study groups and there was no difference in the overall incidence of these events. Conclusions Perioperative administration of IV-Ibuprofen 800 mg every 6 hours in abdominal surgery patient’s decreases morphine requirements and pain score. Furthermore IV-Ibuprofen was safe and well tolerate. Consequently we consider appropriate that protocols for management of postoperative pain include IV-Ibuprofen 800 mg every 6 hours as an option to offer patients an analgesic benefit while reducing the potentially risks associated with morphine consumption.

    2011-01-01

    Myasthenia gravis is an autoimmune neuromuscular disorder. There are several treatment options, including symptomatic treatment (acetylcholinesterase inhibitors), short-term immunosuppression (corticosteroids), long-term immunosuppression (azathioprine, cyclosporine, cyclophosphamide, methotrexate, mycophenolate mofetil, rituximab, tacrolimus), rapid acting short-term immunomodulation (intravenous immunoglobulin, plasma exchange), and long-term immunomodulation (thymectomy). This review explores in detail these different treatment options. Potential future treatments are also discussed. PMID:21845054

  2. Somatic immunoglobulin hypermutation

    OpenAIRE

    Diaz, Marilyn; Casali, Paolo

    2002-01-01

    Immunoglobulin hypermutation provides the structural correlate for the affinity maturation of the antibody response. Characteristic modalities of this mechanism include a preponderance of point-mutations with prevalence of transitions over transversions, and the mutational hotspot RGYW sequence. Recent evidence suggests a mechanism whereby DNA-breaks induce error-prone DNA synthesis in immunoglobulin V(D)J regions by error-prone DNA polymerases. The nature of the targeting mechanism and the t...

    Our understanding of how equine immunoglobulin genes are organized has increased significantly in recent years. For equine heavy chains, 52 IGHV, 40 IGHD, 8 IGHJ and 11 IGHC are present. Seven of these IGHCs are gamma chain genes. Sequence diversity is increasing between fetal, neonatal, foal and adult age. The kappa light chain contains 60 IGKV, 5 IGKJ and 1 IGKC, whereas there are 144 IGLV, 7 IGLJ, and 7 IGLC for the lambda light chain, which is expressed predominantly in horses. Significant transcriptional differences for IGLV and IGLC are identified in different breeds. Allotypic and allelic variants are observed for IGLC1, IGLC5, and IGLC6/7, and two IGLV pseudogenes are also transcribed. During age development, a decrease in IGLVs is noted, although nucleotide diversity and significant differences in gene usage increased. The following paper suggests a standardization of the existing nomenclature of immunoglobulin genes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Pelvic inflammatory disease (PID) is mainly caused by ascending infection from the vaginal flora including the sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, and lower genital tract endogenous anaerobes, leading to serious consequences including infertility and ectopic pregnancy. To evaluate the efficacy and safety of azithromycin in the treatment of PID that requires initial intravenous therapy, we conducted a multicenter, unblinded, non-comparative phase 3 trial. Intravenous azithromycin (500 mg, once daily) for 1 or 2 days followed by oral azithromycin (250 mg once daily) to complete a total of 7 days treatment was administered to 60 Japanese women with acute PID. The clinical and bacteriological responses were assessed at the end of treatment, and on Days 15 and 29. The most commonly detected baseline causative pathogens were C. trachomatis (12 strains), Prevotella bivia (10 strains), Streptococcus agalactiae (7 strains), N. gonorrhoeae and Peptostreptococcus anaerobius (6 strains each). The clinical success rate on Day 15 was 94.1% (48/51 subjects including perihepatitis). The clinical efficacy and bacterial eradication rates against C. trachomatis and N. gonorrhoeae (including 2 quinolone-resistant strains) were both 100%. Common treatment-related adverse events were diarrhoea, injection site pain, and nausea. All adverse events were mild or moderate in severity. Azithromycin intravenous-to-oral switch therapy demonstrated excellent clinical and bacteriological effects for PID caused by various etiologic agents including quinolone-resistant strains and strains with low susceptibility to azithromycin at in vitro testing. The therapy was well tolerated in the treatment of PID in Japanese women. NCT00871494. Copyright © 2014 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.

    Full Text Available Abstract Background Taurolidine (TRD is a novel agent with multimodal antineoplastic effects. We present the case of a tumor remission after intravenous administration of taurolidine in a patient with gastric cancer re-recurrence. Case presentation A 58 years old male patient suffering from a gastric adenocarcinoma was submitted to partial gastrectomy and partial liver resection (pT2, pN1, pM1L (liver segment 2, N0, V0. 24 months later a local recurrence was diagnosed and the patient was reoperated. Postoperatively the patient underwent a palliative chemotherapy with eloxatin, FU, and leucovorin. A subsequent CT-revealed a liver metastasis and a recurrence adjacent to the hepatic artery. After successful radiofrequency ablation of the liver metastasis the patient was intravenously treated with 2% taurolidine. The patient endured the therapy well and no toxicity was observed. CT-scans revealed a stable disease without a tumor progression or metastatic spread. After 39 cycles the patient was submitted to left nephrectomy due to primary urothelial carcinoma and died 2 days later due to myocardial infarction. Postmortem histology of the esophageal-jejunal anastomosis and liver revealed complete remission of the known metastasized gastric adenocarcinoma. Conclusion The intravenous treatment with 2% taurolidine led to a histological remission of the tumor growth without any toxicity for the patient.

    Recent evidence has suggested that intra-arterial thrombolysis may provide benefit beyond intravenous thrombolysis in ischemic stroke patients. Previous meta-analyses have only compared intra-arterial thrombolysis with standard treatment without thrombolysis. The objective was to review the benefits and harms of intra-arterial thrombolysis in ischemic stroke patients. We undertook a meta-analysis of randomized controlled trials comparing the efficacy and safety of intra-arterial thrombolysis with either standard treatment or intravenous thrombolysis following acute ischemic stroke. Primary outcomes included poor functional outcomes (modified Rankin Scale 3-6), mortality, and symptomatic intracranial hemorrhage. Study quality was assessed, and outcomes were stratified by comparison treatment received. Four trials (n = 351) comparing intra-arterial thrombolysis with standard treatment were identified. Intra-arterial thrombolysis reduced the risk of poor functional outcomes (modified Rankin Scale 3-6) [relative risk (RR) = 0·80; 95% confidence interval = 0·67-0·95; P = 0·01]. Mortality was not increased (RR = 0·82; 95% confidence interval = 0·56-1·21; P = 0·32); however, risk of symptomatic intracranial hemorrhage was nearly four times more likely (RR = 3·90; 95% confidence interval = 1·41-10·76; P = 0·006). Two trials (n = 81) comparing intra-arterial thrombolysis with intravenous thrombolysis were identified. Intra-arterial thrombolysis was not found to reduce poor functional outcomes (modified Rankin Scale 3-6) (RR = 0·68; 95% confidence interval = 0·46-1·00; P = 0·05). Mortality was not increased (RR = 1·12; 95% confidence interval = 0·47-2·68; P = 0·79); neither was symptomatic intracranial hemorrhage (RR = 1·13; 95% confidence interval = 0·32-3·99; P = 0·85). Differences in time from symptom onset-to-treatment and type of thrombolytic administered were found

    Henoch-Schönlein purpura is an immunoglobulin A-mediated, small vascular inflammatory disease that can be associated with palpable purpura, arthralgia, abdominal pain, or nephritis. The presence of purpura facilitates the diagnosis of Henoch-Schönlein purpura at the onset of associated symptoms, whereas the absence of purpura makes the diagnosis challenging. It is important to diagnose Henoch-Schönlein purpura with delayed-onset skin purpura to avoid unnecessary surgery for acute abdomen. Most cases of Henoch-Schönlein purpura with severe abdominal pain are treated with low-dose steroids and intravenous immunoglobulin. A 15-year-old Korean girl complained of severe abdominal pain and delayed-onset purpura on admission. Henoch-Schönlein purpura was diagnosed based on endoscopic findings of hemorrhagic duodenitis and duodenal vasculitis and abdominal computed tomography findings of edematous bowels. Two common initial treatments, a low-dose steroid and intravenous immunoglobulin, were administered, but there was no improvement for 1 month. Subsequently, we used high-dose intravenous methylprednisolone pulse therapy (30 mg/kg/day, with a maximum of 1g/day), which dramatically alleviated her abdominal symptoms. High-dose intravenous methylprednisolone pulse therapy can be used as the ultimate treatment for delayed-onset Henoch-Schönlein purpura with severe abdominal pain when symptoms do not improve after low-dose steroid and intravenous immunoglobulin treatments.

    The United States currently has an opioid use disorder epidemic and research evaluating ways to minimize the use of opioids postsurgery are needed. One of these options is intravenous acetaminophen. If the use of preoperative intravenous acetaminophen was found to be effective for cesarean delivery, this would be beneficial for both the mother and breast-feeding neonate. The primary study objective was to see if maternal opioid use was significantly less in the postoperative period for the study group that received 1 g of intravenous acetaminophen preoperatively compared with a control group that received placebo. The secondary objectives were to evaluate maternal length of stay and pain scores postoperatively, and assess the acetaminophen level in cord blood at delivery. This study was a prospective double-blinded randomized placebo-controlled trial. All pregnant patients who entered labor and delivery for a scheduled cesarean from November 2015 through April 2017 were eligible. Once consented, the medication was supplied by the pharmacy department, which performed the blinded randomization. Both the study drug of 1000 mg (1 g) of acetaminophen and placebo of normal saline were distributed as unmarked 100-mL bags administered over 15 minutes just prior to incision. No study personnel from the obstetric or anesthesia departments had any access to the randomization. Based on a power analysis using the published surgical data results, the goal was to obtain a minimum of 100 patients (50 patients in each arm). Primary data collection included demographics, number of opioid doses and morphine milligram equivalents administered to the patient postoperatively, length of stay postdelivery, pain scores, and newborn cord blood acetaminophen levels. Exclusions were maternal acetaminophen allergy, receipt of acetaminophen in the prior 24 hours, opioid use disorder, and hepatitis/liver impairment. Statistics involved χ 2 , Fisher exact, and the Student t test where

    Some guidelines or expert consensus indicate that intravenous (IV) lorazepam (LZP) is preferable to IV diazepam (DZP) for initial treatment of convulsive status epilepticus (SE). We aimed to critically assess all the available data on efficacy and tolerability of IV LZP compared with IV DZP as first-line treatment of convulsive SE. Systematic search of the literature (MEDLINE, CENTRAL, EMBASE, ClinicalTrials.gov) to identify randomized controlled trials (RCTs) comparing IV LZP versus IV DZP used as first-line treatment for convulsive SE (generalized or focal). Inverse variance, Mantel-Haenszel meta-analysis to obtain risk ratio (RR) with 95% confidence intervals (CI) of following outcomes: seizure cessation after drug administration; continuation of SE requiring a different drug; seizure cessation after a single dose of medication; need for ventilator support; clinically relevant hypotension. Five RCTs were included, with a total of 656 patients, 320 randomly allocated to IV LZP and 336 to IV DZP. No statistically significant differences were found between IV LZP and IV DZP for clinical seizure cessation (RR 1.09; 95% CI 1.00 to 1.20), continuation of SE requiring a different drug (RR 0.76; 95% CI 0.57 to 1.02), seizure cessation after a single dose of medication (RR 0.96; 95% CI 0.85 to 1.08), need for ventilator support RR 0.93; 95% CI 0.61 to 1.43, and clinically relevant hypotension. Despite its favorable pharmacokinetic profile, a systematic appraisal of the literature does not provide evidence to strongly support the preferential use of IV LZP as first-line treatment of convulsive SE over IV DZP.

  11. Cost-minimization analysis favours intravenous ferric carboxymaltose over ferric sucrose for the ambulatory treatment of severe iron deficiency.

    Directory of Open Access Journals (Sweden)

    Xavier Calvet

    Full Text Available OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM allows administration of larger iron doses than iron sucrose (IS in each infusion (1000 mg vs. 200 mg. As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM. A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.

    Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an α of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (Pcyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences

    Rubella antibodies are not routinely measured in immunoglobulin products and there is a lack of information on the titer in Australian products. To facilitate future studies of the effectiveness of passive immunisation for preventing rubella and congenital rubella syndrome, this study measured the concentration of rubella-specific antibodies in Australian intramuscular (IM) and intravenous (IV) human immunoglobulin products suitable for post-exposure prophylaxis using a chemiluminescent immunoassay. The GMT ± GSD for the IM product was 19 ± 1.2 IU/mg (2980 ± 1.2 IU/mL). The GMT ± GSD for the IV product was 12 ± 1.5 IU/mg (729 ± 1.5 IU/mL). At present, Australian guidelines recommend offering non-immune pregnant women exposed to rubella 20 mL of intramuscular immunoglobulin within 72 hours of exposure. This equates to 42,160 IU of rubella antibodies if the lowest titer obtained for the Australian IM product is considered.

    Aldosterone prevents the uptake of norepinephrine in the myocardium. Atrial natriuretic peptide (ANP), a circulating hormone of cardiac origin, inhibits aldosterone synthase gene expression in cultured cardiocytes. We evaluated the effects of intravenous ANP on cardiac sympathetic nerve activity (CSNA) and aldosterone suppression in patients with acute decompensated heart failure (ADHF). We studied 182 patients with moderate nonischemic ADHF requiring hospitalization and treated with standard therapy containing intravenous ANP and 10 age-matched normal control subjects. ANP was continuously infused for >96 h. In all subjects, delayed total defect score (TDS), heart to mediastinum ratio, and washout rate were determined by 123 I-metaiodobenzylguanidine (MIBG) scintigraphy. Left ventricular (LV) end-diastolic volume, end-systolic volume, and ejection fraction were determined by echocardiography. All patients with acute heart failure (AHF) were examined once within 3 days and then 4 weeks after admission, while the control subjects were examined only once (when their hemodynamics were normal). Moreover, for 62 AHF patients, plasma aldosterone concentrations were measured at admission and 1 h before stopping ANP infusion. 123 I-MIBG scintigraphic and echocardiographic parameters in normal subjects were more favorable than those in patients with AHF (all p < 0.001). After treatment, all these parameters improved significantly in AHF patients (all p < 0.001). We also found significant correlation between percent changes of TDS and aldosterone concentrations (r = 0.539, p < 0.001) in 62 AHF patients. The CSNA and LV performance were all improved in AHF patients. Furthermore, norepinephrine uptake of myocardium may be ameliorated by suppressing aldosterone production after standard treatment containing intravenous ANP. (orig.)

On the other hand, EVI antibodies are either present or absent in treated patients presenting positive CS but negative CoML. Since CoML detects antibodies associated to resistance, EVI antibodies are not likely to participate in the control of T. cruzi infections although they might be induced by cross-reacting antigens of heart cells and the parasite. They are neither necessarily related to antibodies responsible for CS. Absorption with T. cruzi and heart tissue confirms the suggestion that EVI antibodies are induced by a number of antigenic determinants, most from heart structures with a minor participation of T. cruzi antigens.Anticorpos contra estruturas vasculares do coraçao e interstício de musculatura estriada (anticorpos EVI persistem em pacientes com doenças de Chagas curados por tratamento específico e que apresentam negativos o xenodiagnóstico, sorologia convencional (SC e o teste de lise mediada por complemento (LMCo.

    Using percutaneous nephrolithotomy (PNL), it is easy to reach stones in various parts of the kidney via a single access tract. In the current study, we set out to demonstrate that the intravenous catheter is a safe way to gain renal access, and that PNL is safe in children. We retrospectively reviewed the medical records of patients who underwent PNL as a treatment for renal stone disease at our center between September 2013 and December 2014. There were no specific exclusion criteria. We used 14 gauge intravenous catheter for renal access in all cases. Eleven of the 32 patients (34.4%) were female and 21 (65.6%) were male. The mean ± SD patient age was 4.7 ± 3.71 years (9 months-16 years). Six patients (18.7%) were infants less than 1 year of age. Fifteen of the stones (46.8%) were located in the right kidney, and 17 of the stones (53.1%) were located in the left kidney. The average stone size was 13.9 ± 4.8 mm (range, 12-28). The average duration of operation was 69.7 ± 10.4 minutes (range, 50-110), and the average duration of fluoroscopy was 2.21 ± 1.06 minutes (range, 1-6). There were complications in 5 of the cases (15.6%). The access and dilatation stages are quite important. We propose that the intravenous catheter is a safe and inexpensive tool for renal access in PNL in pediatric age group patients.

    Intravenous (iv) administration of an antidepressant is a common practice in some European countries, particularly in France, Spain, and Italy in the initial treatment phase of hospitalised, severe depressed patients. After a beneficial response is observed, patients are switched to an oral formulation. The approved treatment period of the iv form of citalopram is limited to 8-10 days. The high bioavailability of citalopram permits the use of identical iv and oral doses. Citalopram is a racemate, consisting of a 1:1 mixture of the S- and R-enantiomers. The therapeutically active component is the S-enantiomer (escitalopram). Pharmacokinetic single dose administration studies in healthy subjects have demonstrated that daily oral administration of 20 mg of escitalopram or 40 mg citalopram results in similar plasma concentrations of the S-enantiomer of citalopram. This open-label multicentre French prospective study investigated the tolerability and efficacy of oral escitalopram 10 and 20 mg/day, administered for a 6-week period as continuation treatment of citalopram (20 mg or 40 mg daily) intravenous (iv), in patients with Major Depressive Disorder. A total of 171 patients were enrolled, of whom 147 (85%) completed the study. The mean MADRS score at inclusion (last citalopram dose) was 31.6 +/- 9.9. The total MADRS score decreased after 3 days of oral treatment with escitalopram. Escitalopram demonstrated a continuous effect in treating depressive symptoms throughout the study. The decrease in MADRS mean total score from baseline was statistically significant to each visit (day 3, 15; p or = 50%), and the majority of them were considered remitters (final MADRS score escitalopram was well tolerated in the study population. In all, 57 patients (33%) reported at least one adverse event (AE) during the study (21 patients in the 10 mg group and 36 patients in the 20 mg group); of these, 7 patients (4%) withdrew from the study. The most frequently reported AEs were

    Full Text Available Single long-chain omega-3 fatty acids (e.g. docosahexaenoic acid (DHA or eicosapentaenoic acid (EPA are known for their neuroprotective properties associated with ischemic stroke. This pilot study aimed to test the effectiveness of an acute treatment with a long-chain omega-3 lipid emulsion (Omegaven 10%®, OGV that contains fish oil (DHA 18 mg/ml; EPA 21 mg/ml and α-tocopherol (0.2 mg/ml in a transient middle cerebral artery occlusion (MCAO model of ischemic stroke in mice. For this purpose, female CD-1 mice were anesthetized and subjected to 90 minutes of MCAO. To reflect a clinically relevant situation for an acute treatment, either after induction of stroke or after reperfusion, a single dose of OGV was injected intravenously into the tail vein (5 ml/kg b.w.. A neurological severity score was used to assess motor function and neurological outcome. Stroke-related parameters were determined 24 hours after MCAO. Microdialysis was used to collect samples from extracellular space of the striatum. Mitochondrial function was determined in isolated mitochondria or dissociated brain cells. Inflammation markers were measured in brain homogenate. According to control experiments, neuroprotective effects could be attributed to the long-chain omega-3 content of the emulsion. Intravenous injection of OGV reduced size and severity of stroke, restored mitochondrial function, and prevented excitotoxic glutamate release. Increases of pro-inflammatory markers (COX-2 and IL-6 were attenuated. Neurological severity scoring and neurochemical data demonstrated that acute OGV treatment shortly after induction of stroke was most efficient and able to improve short-term neurological outcome, reflecting the importance of an acute treatment to improve the outcome. Summarising, acute treatment of stroke with a single intravenous dose of OGV provided strong neuroprotective effects and was most effective when given immediately after onset of ischemia. As OGV is an

    While pharmacotherapy with intravenous ceftriaxone, a third-generation cephalosporin, is a potential treatment of Lyme neuroborreliosis, there is concern that it can cause the formation of biliary sludge, leading to hepatobiliary complications such as biliary colic, jaundice and cholelithiasis, which are reflected in changes in serum levels of bilirubin and markers of cholestatic liver injury (alkaline phosphatase and γ-glutamyltranspeptidase). It has been suggested that the naturally occurring substances α-lipoic acid and glutathione may be helpful in preventing hepatic disease. α-Lipoic acid exhibits antioxidant, anti-inflammatory and anti-apoptotic activities in the liver, while glutathione serves as a sulfhydryl buffer. The aim of this study was to determine whether co-administration of α-lipoic acid and glutathione is associated with significant changes in serum levels of bilirubin, alkaline phosphatase and γ-glutamyltranspeptidase during the treatment of Lyme neuroborreliosis with long-term intravenous ceftriaxone. Serum levels of bilirubin, alkaline phosphatase and γ-glutamyltranspeptidase were measured in 42 serologically positive Lyme neuroborreliosis patients before and after long-term treatment with intravenous ceftriaxone (2-4 g daily) with co-administration of oral/intravenous α-lipoic acid (600 mg daily) and glutathione (100 mg orally or 0.6-2.4 g intravenously daily). None of the patients developed biliary colic and there were no significant changes in serum bilirubin, alkaline phosphatase or γ-glutamyltranspeptidase levels over the course of the intravenous ceftriaxone treatment (mean length 75.0 days). Co-administration of α-lipoic acid and glutathione is associated with no significant changes in serum bilirubin, alkaline phosphatase or γ-glutamyltranspeptidase levels during the treatment of neuroborreliosis with intravenous ceftriaxone.

    Purpose: To test the hypothesis that daily intravenous pre-hydration decreases renal toxicity and improves chemotherapy adherence in patients receiving daily cisplatin to concurrent radiotherapy for locally advanced non-small cell lung cancer (NSCLC). Patients and methods: Patients with locally advanced NSCLC were treated between 2008 and August 2012 with daily 6 mg/m 2 cisplatin as a bolus injection in 10 ml; of saline and 66 Gy/24 fr radiotherapy in 32 days. Since January 2011, the administration of cisplatin was routinely preceded by intravenous pre-hydration with 1 L of natriumchloride 0.9%. Patients were divided in a pre-hydrated (PH) and non-pre-hydrated (NPH) cohort. Serum-creatinine and glomerular filtration rate (GFR) were assessed twice weekly during treatment. Retrospectively, baseline data, toxicity, treatment adherence and efficacy data were compared. Results: Of the 356 patients 232 NPH patients and 100 PH patients were eligible. Patient-and treatment characteristics compared equally. The median of the maximum decrease in GFR was 24% and 8% for NPH and PH (p < 0.01), respectively. Sixty-nine percent of the patients in the NPH group completed the 24 administrations of cisplatin, as compared to 83% of the PH group (p < 0.01). Nineteen percent vs. 2% of the patients in the NPH and PH group discontinued cisplatin treatment because of renal toxicity. Surprisingly, the incidence of acute esophageal toxicity grade ⩾2 decreased following prehydration: 62% vs. 34% (p < 0.001) for the NPH and PH groups, respectively. The one-year survival was comparable between groups (75% for NPH and 71% for PH). Conclusion: Daily pre-hydration was associated with a reduced rate of both renal and acute esophageal toxicity and an increased chemotherapy adherence in patients receiving daily dose of cisplatin and concurrent radiotherapy for locally advanced NSCLC

    To investigate the role of quantitative three phase bone scintigraphy (QTPBS) in the evaluation of efficacy of intravenous regional blockade treatment in patients having reflex sympathetic dystrophy (RSD) of the upper extremity. Twenty-six patients with stage-I RSD were focused on in this study. Patients were treated with physical therapy and intravenous (I.V.) regional blockade therapy consisting of dexamethasone and lidocaine. All patients were clinically evaluated before and 1 month after the completion of the therapy protocol. QTPBS was applied to patients before therapy and 1 month after the therapy. As a control group, 11 healthy subjects also underwent QTPBS. Perfusion, hyperemic and fixation indices were calculated from three-phase bone scintigraphy. All patients showed statistically significant clinical improvement after the therapy (p < 0.01). Pre-treatment, perfusion (1.67 +/- 0.63), hyperemic (1.44 +/- 0.48) and fixation (1.69 +/- 0.48) indices of patients were higher than those of healthy subjects (PI: 0.95 +/- 0.05, HI: 0.94 +/- 0.06, FI: 1.01 +/- 0.2) (p < 0.01) and all indices significantly decreased after the treatment (PI: 1.33 +/- 0.46, HI: 1.18 +/- 0.23, FI: 1.42 +/- 0.26) (p < 0.01). I.V. regional blockade therapy combined with corticosteroids is a simple, safe and effective method for the treatment of patients with stage-I RSD in the upper extremity. QTPBS is a valuable and objective method to evaluate the response to therapy and may be useful for staging of patients and predicting the response to therapy.

    Symptomatic intracranial hemorrhage (sICH) is the most feared complication of intravenous thrombolytic therapy in acute ischemic stroke. Treatment of sICH is based on expert opinion and small case series, with the efficacy of such treatments not well established. This document aims to provide an overview of sICH with a focus on pathophysiology and treatment. A literature review was performed for randomized trials, prospective and retrospective studies, opinion papers, case series, and case reports on the definitions, epidemiology, risk factors, pathophysiology, treatment, and outcome of sICH. The document sections were divided among writing group members who performed the literature review, summarized the literature, and provided suggestions on the diagnosis and treatment of patients with sICH caused by systemic thrombolysis with alteplase. Several drafts were circulated among writing group members until a consensus was achieved. sICH is an uncommon but severe complication of systemic thrombolysis in acute ischemic stroke. Prompt diagnosis and early correction of the coagulopathy after alteplase have remained the mainstay of treatment. Further research is required to establish treatments aimed at maintaining integrity of the blood-brain barrier in acute ischemic stroke based on inhibition of the underlying biochemical processes. © 2017 American Heart Association, Inc.

    Stroke patients with unknown onset (UKO) are excluded from thrombolytic therapy. We aim to study the safety and efficacy of intravenous alteplase in ischemic stroke patients with UKO of symptoms compared with those treated within 4.5 hours in a large cohort. Data were analyzed from 47 237 patients with acute ischemic stroke receiving intravenous tissue-type plasminogen activator in hospitals participating in the Safe Implementation of Treatment in Stroke-International Stroke Thrombolysis Registry between 2010 and 2014. Two groups were defined: (1) patients with UKO (n=502) and (2) patients treated within 4.5 hours of stroke onset (n=44 875). Outcome measures were symptomatic intracerebral hemorrhage per Safe Implementation of Treatment in Stroke on the 22 to 36 hours post-treatment neuroimaging and mortality and functional outcome assessed by the modified Rankin Scale at 3 months. Patients in UKO group were significantly older, had more severe stroke at baseline, and longer door-to-needle times than patients in the ≤4.5 hours group. Logistic regression showed similar risk of symptomatic intracerebral hemorrhage (adjusted odds ratio, 1.09; 95% confidence interval, 0.44-2.67) and no significant differences in functional independency (modified Rankin Scale score of 0-2; adjusted odds ratio, 0.79; 95% confidence interval, 0.56-1.10), but higher mortality (adjusted odds ratio, 1.58; 95% confidence interval, 1.04-2.41) in the UKO group compared with the ≤4.5 hours group. Patients treated within 4.5 hours showed reduced disability over the entire range of modified Rankin Scale compared with the UKO group (common adjusted odds ratio, 1.29; 95% confidence interval, 1.01-1.65). Our data suggest no excess risk of symptomatic intracerebral hemorrhage but increased mortality and reduced favorable outcome in patients with UKO stroke compared with patients treated within the approved time window. © 2017 American Heart Association, Inc.

    The level of plasma diamine oxidase (DAO) activity is associated with the maturation and integrity of small intestinal mucosa. This study in rats investigated whether a decreased level of plasma DAO could reflect the severity of mucosal injury due to intravenous 5-fluorouracil (5-FU) treatment. The beneficial effect of soluble dietary fiber (SDF) on preventing diarrhea after 5-FU treatment was also examined. To induce diarrhea, 5-FU (50 mg/kg/day for four days) was administered via the tail vein with or without SDF supplementation. After 5-FU treatment, the majority of rats developed moderate to severe diarrhea, and levels of plasma DAO activity significantly decreased compared to those of control group (P < 0.05). Scanning electron microscopy revealed disarrangement of the small intestinal villi. Contrarily, the rats supplemented with SDF had diarrhea less frequently (50.0 vs. 91.7 %, P = 0.025) on day five, and DAO activity levels were significantly higher than in those rats administered 5-FU alone (8.25 ± 5.34 vs. 5.50 ± 4.32, P = 0.023). In conclusion, plasma DAO activity decreases in response to severe intestinal mucosal injury after 5-FU treatment, and SDF supplementation might be a practical and useful treatment for reducing the intestinal toxicity of 5-FU.

    The aim of this study was to determine the effect of increased levels of prolactin (PRL) on the concentration of immunoglobulins in the blood, colostrum and milk of mares. The study was conducted on 12 mares of the Polish Pony breed (6 in the control and 6 in the experimental group). To induce hyperprolactinaemia in mares of the experimental group, 750 mg sulpiride was administered orally once a day. The initial PRL concentration was 52.22 ± 11.21 ng/ml in the control group and 49.39 ± 10.12 ng/ml in the experimental group. In the subsequent days, the concentration of PRL dynamically changed. Statistical analysis showed highly significant differences (P prolactin is involved in the transfer of immunoglobulins into the colostrum in horses.

    BACKGROUND: Most chemotherapeutics are administrated intravenously (iv), but some are also available in an oral (po) formulation. This study was designed with the primary objective to estimate the patients' preference for po or iv vinorelbine in combination with carboplatin for the palliative...... treatment of non-small cell lung cancer (NSCLC). Secondary aims were to evaluate toxicity, efficacy, and subjective reasons the preference. PATIENTS AND METHODS: Sixty-one patients were randomized in a cross-over trial to two cycles of carboplatin day 1 and vinorelbine day 1 and day 8 iv followed by two...... cycles of carboplatin and vinorelbine po, or the opposite. Patients, who did not show progressive disease after four cycles, had a free choice of iv or po vinorelbine for the next two cycles. RESULTS: Forty-three patients were evaluable for preference and 32 (74%, 95% CI 61-88%) chose po (p

    Sjogren's syndrome, involving sicca symptoms with xerostomia, stomatitis, and considerable pain is a difficult-to-treat autoimmune disease where the treatment options are limited and, as in the case of methotrexate, have a low therapeutic index. This case report concerns a male patient, aged 75 years and vegetarian, with Sjogren's syndrome subsequently confirmed by salivary gland biopsy. Serum antinuclear antibodies (ANA) were elevated (1 : 320). Low serum vitamin B12 and iron levels could be improved after 20 days using vitamin B12 and iron oral supplements. Despite symptomatic treatment, xerostomia, glossitis, and glossodynia were still present, at times marked, after 12 months when the ANA titer was unchanged. Following treatment with an anti-inflammatory polyvalent immunoglobulin formulation (Lactobin®N, 7 g daily), a bovine colostrum concentrate given orally in combination with oral vitamin D3 (2,000 IU daily), sicca symptoms and xerostomia progressively decreased and at day 750 were confined to occasional and minor glossitis of the upper lip. This case report demonstrates the satisfactory control of Sjogren's syndrome using oral polyvalent immunoglobulins with vitamin D3. In contrast to treatment options involving antimalarial drugs and methotrexate, there are no safety issues in patients tolerant to milk products.

    The availability of reptile genomes for the use of the scientific community is an exceptional opportunity to study the evolution of immunoglobulin genes. The genome of Chrysemys picta bellii and Pelodiscus sinensis is the first one that has been reported for turtles. The scanning for immunoglobulin genes resulted in the presence of a complex locus for the immunoglobulin heavy chain (IGH). This IGH locus in both turtles contains genes for 13 isotypes in C. picta bellii and 17 in P. sinensis. These correspond with one immunoglobulin M, one immunoglobulin D, several immunoglobulins Y (six in C. picta bellii and eight in P. sinensis), and several immunoglobulins that are similar to immunoglobulin D2 (five in C. picta belli and seven in P. sinensis) that was previously described in Eublepharis macularius. It is worthy to note that IGHD2 are placed in an inverted transcriptional orientation and present sequences for two immunoglobulin domains that are similar to bird IgA domains. Furthermore, its phylogenetic analysis allows us to consider about the presence of IGHA gene in a primitive reptile, so we would be dealing with the memory of the gene that originated from the bird IGHA. In summary, we provide a clear picture of the immunoglobulins present in a turtle, whose analysis supports the idea that turtles emerged from the evolutionary line from the differentiation of birds and the presence of the IGHA gene present in a common ancestor.

    Full Text Available Intravenous levodopa has been used in a multitude of research studies due to its more predictable pharmacokinetics compared to the oral form, which is used frequently as a treatment for Parkinson’s disease (PD. Levodopa is the precursor for dopamine, and intravenous dopamine would strongly affect vascular tone, but peripheral decarboxylase inhibitors are intended to block such effects. Pulse and blood pressure, with orthostatic changes, were recorded before and after intravenous levodopa or placebo—after oral carbidopa—in 13 adults with a chronic tic disorder and 16 tic-free adult control subjects. Levodopa caused no statistically or clinically significant changes in blood pressure or pulse. These data add to previous data that support the safety of i.v. levodopa when given with adequate peripheral inhibition of DOPA decarboxylase.

    Substance use disorders (SUD) are inheritable and the culprit is hypodopaminergic function regulated by reward genes. We evaluated a natural dopaminergic agonist; KB220 intravenous (IV) and oral variants, to improve dopaminergic function in SUD. Our pilot experiment found a significant reduction of chronic symptoms, measured by the Chronic Abstinence Symptom Severity (CASS) Scale. The combined group (IV and oral) did significantly better than the oral-only group over the first week and 30-day follow-up period. Next, the combination was given to129 subjects and three factors; Emotion, Somatic, and Impaired Cognition, with eigenvalues greater than one were extracted for baseline CASS-Revised (CASS-R) variables. Paired sample t-tests for pre and post-treatment scales showed significant declines (p = .00001) from pre- to post-treatment: t = 19.1 for Emotion, t = 16.1 for Somatic, and t = 14.9 for Impaired Cognition. In a two-year follow-up of 23 subjects who underwent KB220IV therapy (at least five IV treatments over seven days) plus orals for 30+ days: 21 (91%) were sober at six months, 19 (82%) having no relapse; 19 (82%) were sober at one year, 18 (78%) having no relapse; and 21 (91%) were sober two-years post-treatment, 16 (70%) having no relapse. We await additional research and advise caution in interpreting these encouraging results. PMID:23457891

  19. Intra-arterial and intra-venous chemotherapy combined with radiation in the treatment of brain tumours

    The present investigations were undertaken to study the effect of combining different modalities of chemotherapy with radiation in post-operative treatment of brain tumours. The conclusions and clinical implication of the investigations are as follows: The combination of combined intra-arterial chemotherapy followed by radiation leads to an increased median survival with more long term survivors in patients with anaplastic astrocytomas and in patients older than 40 years with astrocytomas. In patients with glioblastoma multiforme, this modality of treatment do not improve median survival, but an increased number of long-term survivors may be seen. Patients younger than 40 years with astrocytomas do not benefit from this modality of treatment. A parallelism exists between sensitivity to chemotherapy and response to radiotherapy. Patients who will benefit from the treatment may be selected early, normally two months after treatment start. Combining intra-arterial chemotherapy and radiation does not lead to an increased incidence of adverse CNS reactions. Specific transient abnormalities in the brain may occur during the first year after treatment and may be misinterpreted as tumour recurrence. EEG may be valuable in predicting adverse CNS reactions following treatment. Nuclear brain scan may be of valuable in selecting the patients who are in danger of developing adverse CNS reactions. Intra-arterial chemotherapy does have an effect in patients with brain tumours who have recurrent tumour after radiation. The most important prognostic factors are age, corticosteroid dependency at treatment start, performance status, histology and frontal lobe location. 103 refs., 2 tabs

    Early administration of intravenous recombinant tissue plasminogen activator (rt-PA) after ischaemic stroke improves outcome. Previous analysis of combined data from individual patients suggested potential benefit beyond 3 h from stroke onset. We re-examined the effect of time to treatment with intravenous rt-PA (alteplase) on therapeutic benefit and clinical risk by adding recent trial data to the analysis. We added data from ECASS III (821 patients) and EPITHET (100 patients) to a pool of common data elements from six other trials of alteplase for acute stroke (2775 patients). We used multivariate logistic regression to assess the relation of stroke onset to start of treatment (OTT) with treatment on favourable 3-month outcome (defined as modified Rankin score 0-1), mortality, and occurrence and outcome of clinically relevant parenchymal haemorrhage. The presence of an arterial occlusion was inferred from the patient's symptoms and absence of haemorrhage or other causes of ischaemic stroke. Vascular imaging was not a requirement in the trials. All patients with confirmed OTT within 360 min were included in the analysis. Treatment was started within 360 min of stroke onset in 3670 patients randomly allocated to alteplase (n=1850) or to placebo (n=1820). Odds of a favourable 3-month outcome increased as OTT decreased (p=0.0269) and no benefit of alteplase treatment was seen after around 270 min. Adjusted odds of a favourable 3-month outcome were 2.55 (95% CI 1.44-4.52) for 0-90 min, 1.64 (1.12-2.40) for 91-180 min, 1.34 (1.06-1.68) for 181-270 min, and 1.22 (0.92-1.61) for 271-360 min in favour of the alteplase group. Large parenchymal haemorrhage was seen in 96 (5.2%) of 1850 patients assigned to alteplase and 18 (1.0%) of 1820 controls, with no clear relation to OTT (p=0.4140). Adjusted odds of mortality increased with OTT (p=0.0444) and were 0.78 (0.41-1.48) for 0-90 min, 1.13 (0.70-1.82) for 91-180 min, 1.22 (0.87-1.71) for 181-270 min, and 1.49 (1.00-2.21) for

    We performed a preliminary feasibility and safety study using intravenous (IV) administration of a platelet glycoprotein IIb/IIIa inhibitor (abciximab) in conjunction with intraarterial (IA) administration of a thrombolytic agent (reteplase) in a primate model of intracranial thrombosis. We introduced thrombus through superselective catheterization of the intracranial segment of the internal carotid artery in 16 primates. The animals were randomly assigned to receive IA reteplase and IV abciximab (n =4), IA reteplase and IV placebo (n =4), IA placebo and IV abciximab (n =4) or IA and IV placebo (n =4). Recanalization was assessed by serial angiography during the 6-h period after initiation of treatment. Postmortem magnetic resonance (MR) imaging was performed to determine the presence of cerebral infarction or intracranial hemorrhage. Partial or complete recanalization at 6 h after initiation of treatment (decrease of two or more points in pre-treatment angiographic occlusion grade) was observed in two animals treated with IA reteplase and IV abciximab, three animals treated with IA reteplase alone and one animal treated with IV abciximab alone. No improvement in perfusion was observed in animals that received IV and IA placebo. Cerebral infarction was demonstrated on postmortem MR imaging in three animals that received IA and IV placebo and in one animal each from the groups that received IA reteplase and IV abciximab or IV abciximab alone. One animal that received IV abciximab alone had a small intracerebral hemorrhage on MR imaging. (orig.)

    High-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs, G3) are aggressive cancers of the digestive system with poor prognosis and survival. Platinum-based chemotherapy (cisplatin/carboplatin + etoposide) is considered the first-line palliative treatment. Etoposide is frequently...... administered intravenously; however, oral etoposide may be used as an alternative. Concerns for oral etoposide include decreased bioavailability, inter- and intra-patient variability and patient compliance. We aimed to evaluate possible differences in progression-free survival (PFS) and overall survival (OS......) in patients treated with oral etoposide compared to etoposide given as infusion. Patients (n = 236) from the Nordic NEC study were divided into three groups receiving etoposide as a long infusion (24 h, n = 170), short infusion (≤ 5 h, n = 33) or oral etoposide (n = 33) according to hospital tradition.

  3. A CASE OF SELECTIVE IMMUNOGLOBULIN A DEFICIENCY ASSOCIATED WITH AUTOIMMUNE GASTRITIS

    Directory of Open Access Journals (Sweden)

    O. V. Moskalets

    2016-01-01

    Full Text Available Selective immunoglobulin A (IgA deficiency is considered to be the most common primary immune deficiency. Up to now, no specific genetic mutation causing this disorder has been found. True prevalence of selective IgA deficiency in the population is unknown, because in most cases it is asymptomatic and occurs as an incidental laboratory finding. In some patients, it can manifest by respiratory and gastrointestinal infections, as well as allergic and autoimmune disorders. According to the literature, autoimmune disorders in patients with selective IgA deficiency have a more aggressive course and a worse prognosis. This clinical case of a combination of selective IgA deficiency and autoimmune gastritis demonstrates that patients with primary immunodeficiency, especially adults, may not know about their disease for a long time. The paper may be of interest for practicing doctors of various specialties, first of all, for gastroenterologists, internists, general practitioners, and is intended to increase awareness about diagnosis of selective IgA deficiency. There is no specific treatment for this immunodeficiency, but one should bear in mind that blood transfusions and intravenous immunoglobulin preparations with high IgA content are contra-indicated in these patients due to a high risk of anaphylactic reactions.

    The aim of this study was to assess the clinical application of a near-patient testing (NPT) device for capillary blood hydroxybutyrate (HOB) measurement in evaluating a new end-point for intravenous insulin therapy in the treatment of diabetic ketoacidosis (DKA) in children. Children fulfilling the criteria for DKA were treated according to an integrated care pathway (ICP) with fluid replacement and insulin infusion. We measured capillary HOB hourly by NPT (Abbott Optium meter, analytical range 0-6.0 mmol/L), venous blood gases 4 hourly, and venous HOB 4 hourly by laboratory enzymatic method and tested all urine passed for ketones. Two possible ICP end-points were compared: A, pH > 7.3 followed by two successive NPT HOB measurements L, and B, pH > 7.3 and urine ketone free (our current end-point). In 35 patient episodes, the ICP was completed (28 to negative ketonuria) without significant variation. Before treatment, median (range) laboratory HOB was 9.5 mmol/L (4.6-15.70 mmol/L), pH 7.18 (6.98-7.38), and standard bicarbonate 11.5 mmol/L (4.3-18.6 mmol/L). ICP end-point A was reached after 17 h (4-39 h), whereas end-point B was not reached until 28 h (14-64 h) after starting treatment. The median lag was 11 h (1-36 h). For 59 paired venous samples (excluding samples with laboratory HOB >6 mmol/L), the relation between NPT (y) and laboratory (x) HOB was y = 0.92x - 0.05, r(2)= 0.94, mean bias -0.25 mmol/L. (i) Serial measurement of NPT HOB allows evaluation of a new, simple, earlier end-point for intravenous insulin therapy. (ii) Agreement between NPT and laboratory HOB was clinically acceptable for HOB levels within the meter's analytical range.

    To improve the scintigraphic detection of bacterial infections a protein charge-purified fraction of polyclonal human immunoglobulin was applied as a radiopharmaceutical. This purification was achieved by attaching the immunoglobulin to an anion-exchanger column and by obtaining the column-bound fraction with buffer. The binding to bacteria in vitro and the target to non-target ratios of an experimental thigh infection with Staphylococcus aureus or Klebsiella pneumoniae in mice were evaluated to compare the purified and the unpurified immunoglobulin. The percentage of binding to all gram-positive and gram-negative bacteria used in this study was significantly (P<0.03) higher for the purified than for the unpurified immunoglobulin. For the in vivo study, mice were infected in the thigh muscle with Staph. aureus or K. pneumoniae. After 18 h 0.1 mg of technetium-99m labelled polyclonal immunoglobulin or [sup 99m]Tc-labelled protein charge-purified polyclonal human immunoglobulin was administered intravenously. At all time intervals the target (infected thighs) to non-target (non-infected thighs) ratios for both infections were significantly higher (P<0.03) for protein charge-purified polyclonal immunoglobulin than for unpurified polyclonal human immunoglobulin. Already within 1 h the infected tissues could be detected by the purified immunoglobulin. It is concluded that [sup 99m]Tc-labelled protein charge-purified immunoglobulin localizes both a gram-positive and a gram-negative thigh infection more intensely and faster than [sup 99m]Tc-labelled unpurified immunoglobulin.

    Ferric Carboxymaltose (FCM), Iron Sucrose (IS) and Oral Iron (OI) are alternative treatments for preoperative anaemia. To compare the cost implications, using a cost-minimization analysis, of three alternatives: FCM vs. IS vs. OI for treating iron-deficient anaemia before surgery in patients with colon cancer. Data from 282 patients with colorectal cancer and anaemia were obtained from a previous study. One hundred and eleven received FCS, 16 IS and 155 OI. Costs of intravenous iron drugs were obtained from the Spanish Regulatory Agency. Direct and indirect costs were obtained from the analytical accounting unit of the Hospital. In the base case mean costs per patient were calculated. Sensitivity analysis and probabilistic Monte Carlo simulation were performed. Total costs per patient were 1827® in the FCM group, 2312® in the IS group and 2101® in the OI group. Cost savings per patient for FCM treatment were 485® compared to IS and 274® compared to OI. A Monte Carlo simulation favoured the use of FCM in 84.7% and 84.4% of simulations when compared to IS and OI, respectively. FCM infusion before surgery reduced costs in patients with colon cancer and iron-deficiency anaemia when compared with OI and IS.

    Neurological disorders are among the main clinical problems affecting preterm children and often result in the development of communication and learning disabilities later in life. Several factors are of importance for brain development, however the role of immunoglobulins (passive immunity transfer) has not yet been investigated. Piglets are born agammaglobulinemic, as a result of the lack of transfer of maternal immunoglobulins in utero, thus, they serve as an ideal model to mimic the condition of immunoglobulin deficiency in preterm infants. Thirty six, unsuckled newborn piglets were fed an infant formula or colostrum and supplemented orally or intravenously with either species-specific or foreign immunoglobulin and then compared to both newborn and sow-reared piglets. Two days after the piglets were born behavioural tests (novel recognition and olfactory discrimination of conspecifics scent) were performed, after which the piglets were sacrificed and blood, cerebrospinal fluid and hippocampi samples were collected for analyses. Both parameters of neuronal plasticity (neuronal maturation and synapse-associated proteins) and behavioural test parameters appeared to be improved by the appearance of species-specific porcine immunoglulin in the circulation and cerebrospinal fluid of the piglets. In conclusion, we postulate possible positive clinical effects following intravenous infusion of human immunoglobulin in terms of neuronal plasticity and cognitive function in preterm infants born with low blood immunoglobulin levels.

    Purpose: to investigate the influence of local density increase by i.v. contrast agent on dose calculation in linac-based radiosurgery (RS) of cerebral arteriovenous malformations (AVMs). Material and methods: RS was performed after three-dimensional (3-D) treatment planning using a total number of nine to 14 beams. Mean target volume was 5.3 cm{sup 3} (range, 0.1-41.2 cm{sup 3}). Mean maximum diameter was 23.2 mm (range, 8-51 mm). Dose deviation was estimated and calculated from the enhanced and unenhanced datasets of 30 patients. Dose calculation was performed using the same RS treatment plan on both datasets. Both plans were standardized to 1 Gy at isocenter with the same dose weight for all beams. Results: mean difference of Hounsfield units ({delta}HU) between enhanced and unenhanced CT was 152 HU (range, 50-350 HU). The estimated dose deviation was {<=} 1% in 80% of cases with a mean deviation of 0.67% and a maximum dose deviation of 1.8%. With increasing {delta}HU and increasing maximum diameter dose deviation increased as well. The calculated overdosage in ten datasets of enhanced and unenhanced CT scans was 0.66% mean (range, 0.2-1.2%). Conclusion: the use of i.v. contrast agent in 3-D treatment planning for RS of cerebral AVMs may lead to an underestimation of actual applied dose. The effect on dose calculation is rather low with dose deviations < +1% in most of the cases. However, there are cases especially in large AVMs with high {delta}HU located next to critical, radiosensitive structures in which an additional unenhanced CT scan is recommended for exact dose calculation to avoid side effects.

    Pre-evaluation of endogenous immunoglobulin levels is a potential strategy to improve the results of intravenous immunoglobulins in sepsis, but more work has to be done to identify those patients who could benefit the most from this treatment. The objective of this study was to evaluate the impact of endogenous immunoglobulins on the mortality risk in sepsis depending on disease severity. This was a retrospective observational study including 278 patients admitted to the ICU with sepsis fulfilling the SEPSIS-3 criteria, coming from the Spanish GRECIA and ABISS-EDUSEPSIS cohorts. Patients were distributed into two groups depending on their Sequential Organ Failure Assessment score at ICU admission (SOFA < 8, n = 122 and SOFA ≥ 8, n = 156), and the association between immunoglobulin levels at ICU admission with mortality was studied in each group by Kaplan-Meier and multivariate logistic regression analysis. ICU/hospital mortality in the SOFA < 8 group was 14.8/23.0%, compared to 30.1/35.3% in the SOFA ≥ 8 group. In the group with SOFA < 8, the simultaneous presence of total IgG < 407 mg/dl, IgM < 43 mg/dl and IgA < 219 mg/dl was associated with a reduction in the survival mean time of 6.6 days in the first 28 days and was a robust predictor of mortality risk either during the acute or during the post-acute phase of the disease (OR for ICU mortality: 13.79; OR for hospital mortality: 7.98). This predictive ability remained in the absence of prior immunosuppression (OR for ICU mortality: 17.53; OR for hospital mortality: 5.63). Total IgG < 407 mg/dl or IgG1 < 332 mg/dl was also an independent predictor of ICU mortality in this group. In contrast, in the SOFA ≥ 8 group, we found no immunoglobulin thresholds associated with neither ICU nor hospital mortality. Endogenous immunoglobulin levels may have a different impact on the mortality risk of sepsis patients based on their severity. In patients with moderate organ failure, the

    Background Several nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to be effective in the treatment of migraine. However, few commercially available NSAIDs can be administered IV. Lysine clonixinate (LC), an NSAID derived from nicotinic acid, has been proved effective in various algesic syndromes (eg, renal colic, muscular pain, nerve compression, odontalgia). The oral formulation of LC has been shown to be effective in the treatment of migraine of moderate severity. Objective The aim of this study was to assess the efficacy and tolerability of the IV formulation of LC in the treatment of severe migraine. Methods This double-blind, randomized, placebo-controlled, prospective study enrolled patients with severe migraine (without aura) as defined by the criteria of the International Headache Society. When patients presented to a neurology hospital with an outpatient headache unit (Instituto de Neurologia Deolindo Couto, Rio de Janeiro, Brazil) with a severe migraine attack that had lasted <4 hours, they were randomized to 1 of 2 groups (IV placebo [25 mL of 0.9% saline] or IV LC [21 mL of 0.9% saline plus 4 mL of LC 200 mg]). Headache intensity and adverse effects (AEs) were assessed before (0 minute) and 30, 60, and 90 minutes after study drug administration. Rescue medication was available 2 hours after study drug administration, and its use was compared between groups. Results Thirty-two patients (23 women, 9 men; mean [SD] age, 32 [2] years; range, 18–58 years) entered the study. Twenty-nine patients (21 women, 8 men; mean [SD] age, 32 [2] years; range, 18–56 years) completed the study. Three patients (all in the placebo group) did not complete the study (1 patient was unable to rate the pain severity after drug administration and 2 patients refused IV drug administration). Among study completers, 17 patients received LC and 12 placebo. At 30 minutes, 1 patient (8.3%) in the placebo group and 5 patients (29.4%) in the LC group were pain free

    The effect of prior antiplatelet (AP) therapy on the risk of hemorrhagic transformation (HT), and on functional outcomes of acute ischemic stroke (AIS) after intravenous thrombolysis (IVT), is not known. We performed a retrospective analysis to determine whether history of AP therapy is associated with post-thrombolysis HT and poor prognosis in AIS patients. Data pertaining to 145 patients with AIS, who underwent IVT between October 2008 and January 2015, were analyzed. The patients were divided into 2 groups based on whether or not they had received prior AP therapy. Neurological outcomes at 24 hours and 3 months after IVT therapy were assessed. Intergroup difference in cost of treatment was also evaluated. A multivariate logistic regression model was used to identify independent predictors of post-thrombolysis HT. Among 145 patients, 23 (15.8%) had received prior AP therapy. On multivariate analyses, older age (odds ratio [OR]: 1.084; confidence interval [CI], 1.028-1.144) and prior AP therapy (OR: 3.318; CI, 1.172-9.398) were found to be independent predictors of HT. In this study, prior AP therapy was independently associated with post-thrombolysis HT in AIS. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Linezolid is 100% bioavailable in oral and intravenous formulations. In a recent prospective, randomized, open-label, comparator-controlled, multicenter, phase 4 clinical trial in adults with complicated skin and soft tissue infections (cSSTIs) caused by methicillin-resistant Staphylococcus aureus (MRSA), linezolid achieved clinical and microbiologic success comparable to appropriately dosed intravenous vancomycin. Although patients were randomly assigned to receive linezolid or vancomycin, the protocol allowed patients to start therapy using oral or intravenous linezolid on the basis of investigator discretion and patient ability to tolerate oral medication. The objective of this study was to assess the efficacy and tolerability of linezolid when administered orally in adults with cSSTI caused by MRSA. In this retrospective analysis, we examined data collected from the aforementioned trial to compare outcomes in patients who received either oral linezolid or intravenous vancomycin therapy. This study analyzed outcomes in patients who received treatment for 7 to 14 days with either oral linezolid (600 mg q12h; n = 95) or intravenous vancomycin (15 mg/kg q12h, adjusted for creatinine clearance and trough concentration; n = 210). By design, these groups were not randomized. Propensity score matching on baseline variables was used to balance these groups by identifying a comparable group of patients who received vancomycin therapy and comparing them with patients who received oral linezolid therapy. Clinical and microbiologic success rates at the end of treatment and the end of the study (EOS) were then directly compared between the groups using matched-pair logistic regression. The tolerability of the 2 treatments (within this matched group) was also described. Ninety-two patients with well-matched baseline characteristics were included in each treatment group. At EOS, the odds ratio for clinical success of oral linezolid therapy vs intravenous vancomycin therapy was

    accumulating in support of calreticulin as a polypeptide binding chaperone. In contrast to mammalian immunoglobulin G (IgG), which has complex type N-glycans, chicken immunoglobulin Y (IgY) possesses a monoglucosylated high mannose N-linked glycan, which is a ligand for calreticulin. Here, we have used solid...... and solution-phase assays to analyze the in vitro binding of calreticulin, purified from human placenta, to human IgG and chicken IgY in order to compare the interactions. In addition, peptides from the respective immunoglobulins were included to further probe the binding specificity of calreticulin....... The experiments demonstrate the ability of calreticulin to bind to denatured forms of both IgG and IgY regardless of the glycosylation state of the proteins. Furthermore, calreticulin exhibits binding to peptides (glycosylated and non-glycosylated) derived from trypsin digestion of both immunoglobulins...

    Full Text Available Background and Aims: A retrospective analysis of treatment outcome using recommended dose of sodium stibogluconate (SSG alone and in combination with other antileishmanial drugs in adults with post-kala-azar dermal leishmaniasis (PKDL attending as outpatients. Methods: A total of 61 patients seen over ten years were included in the report. All had polymorphic lesions. Diagnosis was based on clinical picture, hailing from kala-azar (KA endemic area, exclusion of other dermatoses, histopathology, and therapeutic response. Patients were distributed into two groups: Group I (n = 32, where SSG was given intravenously; in Group II (n = 29, they were allocated to one of four categories using SSG in combination with other drugs. In the first category, SSG was given along with allopurinol (n = 10; in second with rifampicin (n = 6; and in third with both allopurinol and rifampicin (n = 5. In the fourth category, SSG was administered with an immunomodulator (n = 8, Mw vaccine, known to enhance host Th1 response. Results: Only 12 out of 61 patients completed treatment till histopathologic evidence of cure, five in Group I and seven in Group II, no patient being from third category. None had taken SSG without interruptions. Time taken for papulonodules to subside was similar in both groups, but erythema and induration subsided earlier in Group II. Group I patients attained cure after 120 injections while in Group II it took 95 injections in SSG + allopurinol and Mw vaccine categories respectively, and 110 with SSG + rifampicin. Nevertheless this was insufficient to facilitate compliance. Poor performance and high dropouts related to long duration of therapy, thrombophlebitis, difficulty in accessing veins, disabling rheumatic side-effects and practical problems. Liver, renal and pancreatic functions and ECG remained normal. Conclusion: No major advantage was obtained using allopurinol, rifampicin or Mw vaccine along with SSG as compared to SSG alone.

    Intrauterine infection with Ureaplasma spp. is strongly associated with preterm birth and adverse neonatal outcomes. We assessed whether combined intraamniotic (IA) and maternal intravenous (IV) treatment with one of two candidate antibiotics, azithromycin (AZ) or solithromycin (SOLI), would eradicate intrauterine Ureaplasma parvum infection in a sheep model of pregnancy. Sheep with singleton pregnancies received an IA injection of U. parvum serovar 3 at 85 days of gestational age (GA). At 120 days of GA, animals (n=5 to 8/group) received one of the following treatments: (i) maternal IV SOLI with a single IA injection of vehicle (IV SOLI only); (ii) maternal IV SOLI with a single IA injection of SOLI (IV+IA SOLI); (iii) maternal IV AZ and a single IA injection of vehicle (IV AZ only); (iv) maternal IV AZ and a single IA injection of AZ (IV+IA AZ); or (v) maternal IV and single IA injection of vehicle (control). Lambs were surgically delivered at 125 days of GA. Treatment efficacies were assessed by U. parvum culture, quantitative PCR, enzyme-linked immunosorbent assay, and histopathology. Amniotic fluid (AF) from all control animals contained culturable U. parvum. AF, lung, and chorioamnion from all AZ- or SOLI-treated animals (IV only or IV plus IA) were negative for culturable U. parvum. Relative to the results for the control, the levels of expression of interleukin 1β (IL-1β), IL-6, IL-8, and monocyte chemoattractant protein 2 (MCP-2) in fetal skin were significantly decreased in the IV SOLI-only group, the MCP-1 protein concentration in the amniotic fluid was significantly increased in the IV+IA SOLI group, and there was no significant difference in the histological inflammation scoring of lung or chorioamnion among the five groups. In the present study, treatment with either AZ or SOLI (IV only or IV+IA) effectively eradicated macrolide-sensitive U. parvum from the AF. There was no discernible difference in antibiotic therapy efficacy between IV-only and IV
