    Plasmapheresis plays an important role in the acute management of patients with severe myasthenia gravis. Although plasmapheresis is now in use for more than 20 years, some controversies remain about the indication and the place in the therapy. It is generally found that the effect starts one week

    Plasmapheresis can benefit a variety of critically ill patients. A woman with diabetic ketoacidosis and severe hypertriglyceridemia was treated with plasmapheresis when conventional treatments did not markedly reduce her triglyceridemia. The patient was admitted to a medical intensive care unit because of diabetic ketoacidosis with severe lipemia. The lipemia-associated interference in laboratory studies made treatment of electrolyte abnormalities extremely difficult. The hypertriglyceridemia was initially treated with insulin, antilipidemic medications, and heparin, but the levels of triglycerides remained elevated, delaying results of needed laboratory studies for hours. After plasmapheresis, the serum level of triglycerides decreased by 77% in less than 24 hours. Severe lipemia interferes with photometric laboratory studies, yielding an underestimation of serum levels of electrolytes. Plasmapheresis is safe, rapid, and effective for emergent management of severe hypertriglyceridemia in critically ill patients. The impact of the procedure on critical care nursing is growing as nurses become involved in the treatment and follow-up care of patients who have plasmapheresis.

    In experiments with dogs exposed to 2.9 Gy (LD 80/45 ) it was found that plasmapheresis treatment 4-6 h after irradiation reduce the severity of the radiation sickness clinical manifestations and post-radiation toxemia thus increasing the rate of animal survival up to 60 %. Sham plasmapheresis included all the manipulations of plasmapheretic treatment except plasma substitution and had no detoxication effect and did not affect the irradiated animals survival. This is evidence for leading role of detoxiation in the mechanisms of th therapeutic action of plasmapheresis in acute irradiation

    Plasmapheresis performed weeks before an operation producing autologous plasma has proved to be of benefit in elective operations. First experiences in acute plasmapheresis, which is performed immediately before the operation, have been reported recently. When acute plasmapheresis is used in cardiac operations, however, it must be viewed in connection with other techniques for reducing blood consumption such as the Cell Saver (CS) and ultrafiltration devices. In 60 patients undergoing elective aortocoronary bypass grafting, acute plasmapheresis was performed, producing either platelet-poor plasma or platelet-rich plasma, in combination with either the Cell Saver or hemofiltration. Fluid balance during cardiopulmonary bypass was significantly lower in the hemofiltration patients. Postoperatively, none of these patients received donor blood, whereas 4 patients of the Cell-Saver groups needed packed red blood cells. AT-III, fibrinogen, the number of platelets, albumin, total protein, and colloid osmotic pressure were less compromised when hemofiltration was used in combination with acute plasmapheresis in contrast to combination with the Cell-Saver technique. Plasma hemoglobin was without differences during the investigation period, and polymorphonuclear elastase was less increased when platelet-rich plasma was produced preoperatively. On the first postoperative day, most of the differences between the groups had already disappeared. We conclude that when acute plasmapheresis is used in cardiac operations, discarding of plasma by the Cell Saver should be avoided and ultrafiltration devices should replace centrifugation techniques for blood conservation.

    Full Text Available Although severe hypertriglyceridemia is rarely seen in pregnancy, it may result in acute pancreatitis leading to increased morbidity in both mother and fetus. Restriction of dietary lipid and lipid-lowering medications are the cornerstones of the treatment. Experiences with plasmapheresis are limited. Herein, a pregnant woman with hypertriglyceridemia who was given preconceptional counseling and medical therapy and kept under close observation since the early weeks of gestation, succesfully managed with dietary lipid restriction and especially with serial plasmapheresis is discussed. Her previous pregnancy was remarkable with fetal demise due to acute pancreatitis at 24th weeks of gestation. It is important that the clinicians have a clear understanding of the normal lipid profile during pregnancy, the clinical picture, the potential complications, available treatment options of hypertriglyceridemia particularly during pregnancy.

    Antibody-mediated rejection (AMR) continues to pose a serious challenge in renal transplantation with potentially devastating consequences. Treatment options for this condition include plasmapheresis, high-dose intravenous immunoglobulin (IVIG), plasmapheresis with low-dose IVIG, and the use of rituximab (anti-CD20 chimeric antibody). We previously reported on the short-term outcome of plasmapheresis as a rescue therapy for AMR in our centre. We now report on the long-term follow up.

    Full Text Available Nephrogenic systemic fibrosis (NSF is a recently identified idiopathic cutaneous fibrosing disorder that occurs in the setting of renal failure. The disease initially called nephrogenic fibrosing dermopathy is closely linked to exposure to gadolinium-based contrast media used during magnetic resonance imaging in patients with renal insufficiency. Although little is known about the pathogenesis of this disease, the increased expression of transforming growth factor-beta has been demonstrated recently. Herein, we present a case of NSF was partially treated due to a moderate and temporary response to plasmapheresis with no recurrence for 6 months, but returned at the end of 6th month.

    Full Text Available Background: Guillain–Barre syndrome (GBS is an autoimmune acute inflammatory demyelinating polyneuropathy affecting the peripheral nervous system treated with high-dose immunoglobulin, physical therapy, or plasmapheresis. Immunoglobulins are expensive and even plasmapheresis might not be affordable to patients visiting government set-ups.Aims: This study was undertaken to emphasize the efficacy of plasmapheresis in treatment of adult GBS patients and to narrate methods of reducing the economic burden in the treatment of these patients using modified plasmapheresis. Methods: A study was conducted on 12 adult GBS patients at Sir Takhtasinhji General Hospital, Bhavnagar from July 2012 to July 2014. Patients were assessed on a 6-point disability scale. They were treated with plasmapheresis over 10 days with REF627 kit from Haemonetics Corporation Limited on MCS+ machine. Improvement was noted by the change in the disability scale score and expenses of various modes of treatment were also considered. Results: Seventy-five percent showed improvement at the end of the treatment. The cost of modified plasmapheresis was Rs. 8000/cycle, i.e., Rs. 40,000/patient. Conclusion: Plasmapheresis along with proper supportive measures is a more cost-effective efficacious mode of therapy in adult patients of GBS. Further, modified plasmapheresis using REF627 kit and 6% hexastarch as replacement fluid on MCS+ apheresis machine reduces the cost of therapy for poor patients visiting government set-ups.

    BACKGROUND: It has been proposed that plasmapheresis is most effective when applied early in Gram-negative sepsis. We therefore studied the effect of early plasmapheresis on immunity in experimental Escherichia coli endotoxin-induced sepsis. METHODS: 20 pigs received 30 microg/kg of E. coli...... endotoxin. 40 min later, half of the pigs were treated with plasmapheresis which lasted 4 h. The adhesion molecules, the oxidative burst, the number of neutrophils in blood and lungs, and cytokines were measured. RESULTS: Infusion of endotoxin was associated with activation of adhesion molecules increased...... oxidative burst, increased concentration of cytokine, and accumulation of granulocytes in lung tissue. Plasmapheresis reduced the oxidative burst, and there was a tendency towards a reduced accumulation of granulocytes in the lung. CONCLUSION: Though plasmapheresis was initiated early after the endotoxin...

    Antiphospholipid antibody syndrome (APS) is a systemic autoimmune disease characterized by arterial and/or venous thrombosis, recurrent abortions and detection of antiphospholipid antibodies. In fulminant cases, involvement of multiple organs can lead to significant morbidity and even fatal outcomes, so that a rapid, interdisciplinary treatment is needed. Here, we describe the case of a 39-year-old woman with a severe hard-to-treat APS with arterial occlusion and progressive skin necrosis, who was successfully treated with a combination therapy with plasmapheresis and rituximab. The treatment led to complete remission of the skin lesions for over a year. Clinical response correlated with a long-lasting reduction of antiphospholipid antibodies and B-cell depletion. This case demonstrates the use of antiphospholipid antibodies for monitoring APS-activity and shows that this severe vascular disease requires rigorous therapeutic approaches.

    Full Text Available A 12 year old, 38 kg, mix-breed, intact male dog presented with a 20 day history of clinical signs consistent with hyperviscosity syndrome secondary to multiple myeloma. The dog received three double filtration plasmapheresis treatments on day 0, 7 and 22 after presentation. A significant (p<0.05 reduction in serum total protein, alpha-2 and gamma globulins was found following each treatment. These reductions were accompanied by a complete resolution, although temporary, of the clinical signs of hyperviscosity syndrome. The present study reported for the first time the use of double filtration plasmapheresis to reduce clinical signs of hyperviscosity syndrome in a dog with multiple myeloma.

    Acute humoral rejection (AHR) is uncommon after ABOcompatible liver transplantation. Herein, we report two cases of AHR treated with plasmapheresis and rituximab in two ABO-compatible liver-transplant patients with preformed anti-human leukocyte antigen donor-specific antibodies. Patient 1 experienced a biopsy-proven AHR at day 10 post-transplant. She was treated by steroid pulses, and OKT3. Because of persisting signs of biopsy-proven AHR at day 26, she was treated by plasmapheresis and rituximab. Liver enzyme levels did not improve, and she died on day 41. Patient 2 experienced a biopsy-proven AHR on day 10 post-transplant. She was treated by steroid pulses, plasmapheresis, and rituximab.Liver enzymes returned to within normal range 18 dafter diagnosis. Liver biopsies, at 3 and 9 mo post-transplant,showed complete resolution of AHR. We conclude that plasmapheresis should be started as soon as AHR is diagnosed, and be associated with a B-cell depleting agent. Rituximab may be considered as a first-line therapy.

    Hypertriglyceridemia and hyperlipidemia are the most remarkable metabolic complications seen with long-term sirolimus therapy. We report the case of a 36-year-old woman status post bilateral lung transplantation on a maintenance immunosuppression regimen of sirolimus, tacrolimus, and prednisone who presented with status migrainosus, chest pain, abdominal discomfort, and triglyceride levels greater than 4425 mg/dL. In previously reported cases of severe hypertriglyceridemia that developed on maintenance sirolimus therapy, plasmapheresis has been utilized as an early strategy to rapidly lower triglycerides in order to minimize the risk of acute complications such as pancreatitis, but our case was managed medically without plasmapheresis. The most recent triglyceride was down to 520 mg/dL 2 months after discontinuation of sirolimus. We estimate the probability of this reaction to sirolimus as probable based on a score of 5 points on the Naranjo scale. This is the first case report to our knowledge that highlights the sole use of oral lipid-lowering drug agents to treat severe hypertriglyceridemia secondary to sirolimus without the use of plasmapheresis. Sirolimus-induced severe hypertriglyceridemia can be managed with oral lipid-lowering agents without plasmapheresis. Clinician needs to be aware of the importance of baseline and regular triglyceride monitoring in patients on sirolimus.

    2017-03-01

    Full Text Available Chylomicronemia is a severe type of hypertriglyceridemia characterized by chylomicron accumulation that arises from a genetic defect in intravascular lipolysis. It requires urgent and proper management, because serious cases can be accompanied by pancreatic necrosis or persistent multiple organ failure. We present the case of a 1-month-old infant with chylomicronemia treated by plasmapheresis. His chylomicronemia was discovered incidentally when lactescent plasma was noticed during routine blood sampling during a hospital admission for fever and irritability. Laboratory investigation revealed marked triglyceridemia (>5,000 mg/dL with high chylomicron levels. We therefore decided to perform a therapeutic plasmapheresis to prevent acute pancreatitis. Sequence analysis revealed a homozygous novel mutation in exon 4 of GPIHBP1: c.476delG (p.Gly159Alafs. Glycosylphosphatidylinositol-anchored high density lipoprotein-binding protein 1 (GPIHBP1 stabilizes the binding of chylomicrons near lipoprotein lipase and supports lipolysis. Mutations of GPIHBP1, the most recently discovered gene, can lead to severe hyperlipidemia and are known to make up only 2% of the monogenic mutations associated with chylomicronemia. The patient maintains mild hypertriglyceridemia without rebound after single plasmapheresis and maintenance fibrate medication so far. Here, we report an infant with chylomicronemia due to GPIHBP1 mutation, successfully treated by plasmapheresis.

    2017-01-01

    Full Text Available Currently in the literature there are insufficient data on the use of efferent hemocorrection methods in neonatal practice. The basic principle of this method is the removal of plasma containing endotoxins and exotoxins and other pathological substances, replacing it with donor plasma, colloid and crystalloid solutions. The therapeutic effect of plasmapheresis includes detoxification, anti-inflammatory and immunomodulatory effects by removing toxins and removal of circulating immune complexes, inflammatory mediators, and activated structures of the complement system. Discrete plasmapheresis in neonatal practice may be used in any body mass of the patient. This article describes a clinical case of successful application of discrete plasmapheresis in full-term newborn baby is in critical condition. The severity was due to severe early neonatal sepsis, development of multiple organ failure and accompanying RH-conflict. After two sessions of plasmapheresis was observed a positive clinical effect in reducing intoxication, systemic inflammatory response syndrome. Reducing the level of bilirubin is allowed to avoid the operation replacement blood transfusion.

    Severe hypertriglyceridemia (HTG) leads to major complications such as acute pancreatitis. Lipoprotein apheresis has been proposed as a therapeutic tool for decreasing triglyceride levels, although experience is limited. To describe our experience with double filtration plasmapheresis (DFPP) in patients with severe HTG and pancreatitis in the plasmapheresis unit of a tertiary hospital in Spain. We recruited 4 patients with severe HTG (triglycerides [TGs] >1000 mg/dL) and acute pancreatitis. All the patients underwent DFPP as part of their treatment. Epidemiologic and laboratory data were collected before and after each plasmapheresis session. The average TG level before plasmapheresis was 3136 mg/dL (35.44 mmol/L; range, 1306-6693 mg/dL, 14.76-75.63 mmol/L), and the average Acute Physiology And Chronic Health Evaluation (APACHE) II level before the first session was 6 (range, 3-8). All patients made a full recovery, with a significant improvement in TG levels after plasmapheresis. The mean number of sessions was 2.1 (range, 1-3), and mean TG level after plasmapheresis was 428 mg/dL (4.84 mmol/L; range, 169-515 mg/dL; 1.91-5.82 mmol/L). After the first session, the mean decrease in TG levels was 69.16% (2169 mg/dL, range, 945-5925 mg/dL; 24.51 mmol/L, range, 10.78-66.95 mmol/L), and after the last session, TG levels fell by 89.09% (2794 mg/dL, range, 945-6198 mg/dL; 31.57 mmol/L, range, 10.68-70.04 mmol/L). None of the patients developed complications related to plasmapheresis. According to available evidence and our own experience, DFPP can be an effective and rapid treatment option in patients with severe HTG and complications. However, further research, including randomized controlled studies, is necessary. Copyright © 2015 National Lipid Association. Published by Elsevier Inc. All rights reserved.

    We report the case of a 36-year old pregnant woman with a Kell alloimmunization (anti-K1), probably secondary to a previous blood transfusion, and a severe hemolytic disease of the fetus. Once the first fetal blood transfusion by cordocentesis was performed, we started treatment with repeated plasmapheresis to maintain anti-K1 titer below 1:32. With this scheme we did not need to perform a second intrauterine fetal blood transfusion and only mild anemia was found in the newborn. Taking into account that the rate of serious complications with plasmapheresis is lower than that related with intrauterine blood transfusion, this could be an alternative approach to repeated transfusions.

    Severe hypertriglyceridemia is a common indication for the need of plasma exchange in treatment of hypertriglyceridemic-induced pancreatitis when normal therapies fail to garner a response. Application of plasmapheresis to prevent complication of hypertriglyceridemia is limited because of its cost and availability. We present a case of a 44-year-old man with metabolic syndrome and a medical history of secondary polycythemia in obesity hypoventilation syndrome, whose laboratory tests revealed a triglycerides value of 3965 mg/dL. To prevent the complication of pancreatitis due to hypertriglyceridemia, we performed plasma exchange 3 times when conventional treatments did not sufficiently reduce the high level of triglycerides. A review of the current available literature was therefore conducted to provide an overview of the present data on apheretic treatment for patients with severe hypertriglyceridemia. Several case reports and case series have used plasmapheresis in acute treatment of hypertriglyceridemia pancreatitis related. In our case, the choice of plasmapheresis was applied in prevention of possible complications of hypertriglyceridemia.

    2015-01-01

    Full Text Available An imbalance of angiogenic and antiangiogenic placental factors such as endoglin and soluble fms-like tyrosine kinase 1 has been implicated in the pathophysiology of preeclampsia. Extraction of these substances by plasmapheresis might be a therapeutical approach in cases of severe early-onset preeclampsia. Case Report. A 21-year-old primigravida with antiphospholipid syndrome developed early-onset preeclampsia at 18 weeks’ gestation. She was treated successfully with plasmapheresis in order to prolong pregnancy. Endoglin and sflt-1-levels were measured by ELISA before and after treatment. Endoglin levels decreased significantly after treatment (p < 0.05 and showed a significant decrease throughout pregnancy. A rerise of endoglin and sflt-1 preceded placental abruption 4 weeks before onset of incident. Conclusion. Due to the limited long-term therapeutical possibilities for pregnancies complicated by PE, plasmapheresis seems to be a therapeutical option. This consideration refers especially to pregnancies with early-onset preeclampsia, in which, after first conventional treatment of PE, prolongation of pregnancy should be above all.

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

    The objective of this paper is to assess the role of plasmapheresis in immune hematology by reviewing published clinical outcome data and narrative review articles. This information will be used to define evidence levels for appraisal of the efficacy and rank of plasmapheresis among other management options. This evidence-based strategy conforms to the concepts of the American Society of Hematology (ASH). as put forward in 1996 in the context of immune thrombocytopenia (ITP) treatment. The term 'experimental' is used to describe indications where the only scientific evidence of the efficacy of plasmapheresis consists of pathophysiological reasoning and empiric clinical findings. We reviewed the available literature on the use of plasmapheresis in autoimmune hemolytic anemia (AIHA), hemolytic disease of the newborn (HDN), autoimmune thrombocytopenic purpura (AITP), heparin-induced thrombocytopenia type II (HIT II), post-transfusion purpura (PTP), refractoriness to platelet transfusion (RPT), coagulation factor inhibitor (CFI) and catastrophic antiphospholipid syndrome (CAS). Plasmapheresis completes the spectrum of management options as it eliminates physically circulating free antibodies involved in the pathogenesis of these immune hematological syndromes. Because of the paucity of data, evidence levels had to be defined based on the findings of uncontrolled case series and the opinions of independent experts. In many cases, randomized clinical trials were not feasible because the syndromes are so rare. When defined as an 'experimental indication', plasmapheresis has a firm scientific basis, but larger scale clinical experience with the method is still lacking. In these cases, the detection and monitoring of symptomatic disease-related circulating free antibodies or immune complexes is a mandatory prerequisite for the use of plasmapheresis. The therapeutic benefit of plasmapheresis is substantiated by the level V of evidence of its efficacy in treatment of HDN, HIV

    Full Text Available Introduction. One of the current tasks of transplantology is to overcome «graft-host» immune confl ict. Partially this confl ict is caused by the presence of circulating pre-existing antibodies. Highly sensitized patients have a greater risk of rejection and subsequent graft loss. There are several methods to remove the antibodies, one of which is a double fi ltration plasmapheresis (DFPF. This report presents our experience of DFPF in recipients of high immunologic risk.Aim: to compare the effectiveness of traditional and double filtration plasmapheresis in desensitization of patients with high risk of immunological complications.Methods. The study included 30 patients after kidney transplantation. All patients were classifi ed as high-immunologic risk group. In 15 patients of study group we performed DFPF, in 15 patients of comparison group – traditional plasmapheresis. We monitored the immune status: markers of humoral immunity activation – IgG, IgM, IgA before and after the procedures. DFPF procedure was performed on OctoNova (MeSys, Germany with a plasmafi lter and plasma components separator. Protocol biopsies were performed on days 30 and 90.Results. The concentration of antibodies may be effectively reduced with DFPF. Total IgM and IgG antibodies were reduced by 30–55% of the original level. There was a less albumin loss in case of DFPF application. There is 1 patient with antibody-mediated rejection with graft dysfunction in study group. There are no signs of rejection in 30- and 90-day biopsy in study group. But there were three patients with subclinical antibody-mediated rejection in the comparison group.Conclusion. DFPF can safely and effectively reduce the high titers of antibodies that are responsible for humoral rejection of renal allograft. Reduction of antibodies in sensitized patients immediately after transplantation may improve graft function.

    The paper provides the results of a follow-up of 70 patients with active pulmonary tuberculosis in whom the administration of antituberculous drugs induced eosinophilia and bronchial obstructive syndrome. To eliminate the side effects of antituberculous therapy, a plasmapheresis regimen was performed in 44 patients, the remaining patients were given only bronchodilators and antihistamine drugs. Plasmapheresis as a means for correcting drug-induced eosinophilia and bronchial obstructive syndrome was found to be more effective than drug therapy and, in some cases, enabled antituberculous therapy to be continued, without changing a combination of drugs. It is recommended that plasmapheresis should be used in cases of inadequate efficiency of conventional methods for correcting drug intolerance.

    Here we report a case of planned pregnancy in a Hyper immunized Rh D negative Banker lady who was interested to have a healthy baby in her fourth Gestation as previous conceptions were ended by intra uterine death (IUDs) due to Rhesus Hemolytic diseases of new born (HDN) which is a condition where the lifespan of the infant's red cells is shortened by the action of specific antibodies derived from the mother by placental transfer. The disease begins in intrauterine life and is therefore correctly described as hemolytic disease of the fetus (HDF) and new born, but the simple term HDN has been used for a long time and can be taken to include hemolytic disease of the fetus (HDF). This hemolytic process takes place in utero and results in marked compensatory overproduction of young nucleated red cells in fetal erythropoietic sites. For this reason the disease also called erythroblastosis foetalis. Elective plasmapheresis done at the Transfusion Medicine Department of BSMMU, Dhaka on her, 800 ml. plasma were extracted in 4 different sessions during her antenatal period. One healthy male baby was delivered by LUCS at 32 weeks of pregnancy; the Baby has to receive 170 ml. O negative fresh Whole Blood as Exchange Transfusion to correct mild hyper bilirubinimia and anemia. Manual plasmapheresis may thus be practiced to all Hyper-immunized carrying mothers to prevent intra uterine death (IUD) in Rhesus D negative carrying mothers.

    Full Text Available Introduction. The development of immunological confl ict in the form of host-versus-graft reaction has always been main problem in transplantation. The worst case is the development of humoral rejection with the presence of circulating immune complexes and antibodies. There are several methods for quick removal of antibodies; among those are traditional plasmapheresis (PA and double fi ltration plasmapheresis (DFPF. In this paper we present our experience with these two methods and give a comparative evaluation of the effectiveness in the treatment of acute humoral rejection in renal allograft. Aim: to compare the effectiveness of traditional and double fi ltration plasmapheresis while processing different volumes of plasma in the treatment of host-versus-graft disease after kidney transplantation.Methods. The study included 58 patients after kidney transplantation. All patients had increased activity of humoral immunity, which was confi rmed by immunofl uorescence with luminescence C4d complement component. In 26 patients we performed DFPF, in 32 patients – traditional PA. We divided the DFPF patients into 4 subgroups depending on the amount of processed plasma: > 50% (5 patients, 50–100% (8 patients, 100–150% (7 patients, 150–200% (6 patients of circulating plasma volume. We also divided PA patients into four subgroups depending on the volume of plasma removed: >50% (8 patients, 50–70% (12 patients, 70–90% (7 patients, 90–110% (5 patients of the volume of circulating plasma. We monitored the immune status with markers of humoral immunity activation IgM, IgG before and after each of the procedures.Results. Each procedure of traditional PA and DFPF was accompanied by a marked decrease in blood concentrations of IgM and IgG antibodies. Their level decreased by an average of 30–55% of the original. However, some patients in both groups showed an increase in the concentration of these immunoglobulins in 1–2 days

    Hypertriglyceridemia is one of the rare causes of the acute pancreatitis. The prevalance of hypertriglyceridemia has increased recently due to the changing eating habits, sedentary lifestyle, alcohol consumption, obesity and concomitant diabetes mellitus. Therefore, the frequency of the acute pancreatitis due to hypertriglyceridemia may increase in coming years. Diagnosis of the acute pancreatitis by hypertriglyceridemia can be overlooked easily and may be very severe if untreated accurately on time. In addition to the standard management of pancreatitis, specific treatment for hypertriglyceridemia that is insulin, heparin and anti-hypertriglyceridemic drugs are used. Therapeutic plasmapheresis is the last treatment option and seems the most effective one in this subject through developing device and membrane technologies when we review the current literature. Not only triglycerides but also proinflammatory cytokines and adhesion molecules that play an active role in pathogenesis are removed by plasmapheresis. So, the effectiveness of treatment appears promising. However, the exact pathophysiology of hypertriglyceridemia-induced pancreatitis could not be fully understood and the majority of published experience comes from the case reports and the benefit of randomized clinical trials is not available. Therefore, there are no data about what are the exact indications and when we start therapeutic plasmapheresis in literature. This manuscript describes our hospital experience with treatment options and analyzes reports published recently about plasmapheresis as a treatment modality for hypertriglyceridemia induced acute pancreatitis. © Acta Gastro-Enterologica Belgica.

    The acronym PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) has been assigned to a subgroup of patients experiencing pediatric onset obsessive-compulsive symptoms and tics as a result of autoimmune response to group A beta-hemolytic streptococcal infection. It has been hypothesized that an immune process initiated by infection affects the basal ganglia and causes neuropsychiatric symptoms. In cases with severe neuropsychiatric symptoms, the use of treatment strategies that interrupt the autoimmune process responsible for the pathogenesis of PANDAS, such as therapeutic plasmapheresis or intravenous immunoglobulin, has been proposed. In this paper, we discuss the effect of plasmapheresis treatment in 4 adult cases of obsessive-compulsive disorder and tic disorder triggered by streptococcal infections.

    Current reimbursement policy of health insurance for therapeutic plasmapheresis requires proof of efficacy using the concept of evidence-based medicine. The aim of this paper is to review the outcome of plasmapheresis used to treat thrombotic microangiopathy (TMA)-associated syndromes in the last decade to provide scientific evidence to back up reimbursement applications. The strength of evidence of each reviewed study was assessed using the five levels of evidence criteria as defined by the American Society of Hematology in 1996 for assessment of the treatment of immune thrombocytopenia. The level Experimental indication was added for situations where only case reports or small series supported by pathophysiological reasoning are available. The definitions of evidence used in this paper are as follows: Level I, randomized clinical trial with low rates of error (p historical control group; Level V, case series without a control group or expert opinion; and Experimental, case reports and pathophysiological reasoning. The results of this analysis based on the published data is summarized as follows: The indication of plasmapheresis is assigned to Level IV evidence for thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS); cancer/chemotherapy-associated TTP/HUS is assigned to Level V evidence; and TTP/HUS refractory to standard plasma exchange and post-bone marrow transplantation TTP/HUS are assigned to Experimental indication. For both subsets, protein A immunoadsorption is reportedly successful. The other TMA-associated syndromes, hemolysis elevated liver enzymes low platelets and HUS in early childhood, are no indication of plasmapheresis. Two randomized clinical trials were performed in order to demonstrate the superiority of plasma exchange/fresh frozen plasma (PEX/FFP) over plasma transfusion in the management of TTP/HUS. The results prove the greater clinical success of the latter type of plasma administration. Standard PEX/FFP has reduced the

    Full Text Available Introduction: In Guillain Barre syndrome (GBS, worsening of weakness or disability after initial period of recovery or stabilization is described as treatment-related fluctuations (TRF. Aim: This study aims to describe the clinical characteristics and outcome of six patients with GBS and TRF. Patients and Methods: Six patients with GBS fulfilling NINCDS criteria, evaluated at a tertiary care university hospital during 2008–2017, were diagnosed to have TRF. They form the basis of this report. Results: All patients were men and their mean age was 40 years. At presentation, mean duration of illness was 15 days; the illness had plateaued in three and progressive in other three patients. Two of the four patients had variant GBS. Initially, five patients were treated with large volume plasmapheresis (LVPP and one patient with methyl prednisolone. At 17–28 days after disease onset, three patients developed new neurologic deficits (bilateral facial paresis in two; paralytic ileus in one. Other three patients with worsening of limb weakness (medical research council sum score of >5 and disability (Hughes disability grade by ≥1 fulfilled Kleyweg's criteria for TRF. All the six patients were treated with the completion of five cycles or additional cycles of LVPP. Conclusion: Awareness about TRF is essential for correct diagnosis and management of patients with GBS.

    Concerns regarding the safety of transfused blood have generated considerable enthusiasm for the use of technologies intended to reduce the use of allogeneic blood (blood from an unrelated donor). Platelet-rich plasmapheresis (PRP) offers an alternative approach to blood conservation. To examine the evidence for the efficacy of PRP in reducing peri-operative allogeneic red blood cell (RBC) transfusion, and the evidence for any effect on clinical outcomes such as mortality and re-operation rates. We identified studies by searching MEDLINE (1950 to 2009), EMBASE (1980 to 2009), The Cochrane Library (Issue 1, 2009), the Internet (to March 2009) and the reference lists of published articles, reports, and reviews. Controlled parallel group trials in which adult patients, scheduled for non-urgent surgery, were randomised to PRP, or to a control group which did not receive the intervention. Primary outcomes measured were: the number of patients exposed to allogeneic RBC transfusion, and the amount of RBC transfused. Other outcomes measured were: the number of patients exposed to allogeneic platelet transfusions, fresh frozen plasma, and cryoprecipitate, blood loss, re-operation for bleeding, post-operative complications (thrombosis), mortality, and length of hospital stay. Treatment effects were pooled using a random-effects model. Trial quality was assessed using criteria proposed by Schulz et al (Schulz 1995). Twenty-two trials of PRP were identified that reported data for the number of patients exposed to allogeneic RBC transfusion. These trials evaluated a total of 1589 patients. The relative risk (RR) of exposure to allogeneic blood transfusion in those patients randomised to PRP was 0.73 (95%CI 0.59 to 0.90), equating to a relative risk reduction (RRR) of 27% and a risk difference (RD) of 19% (95%CI 10% to 29%). However, significant heterogeneity of treatment effect was observed (p transfused (weighted mean difference [WMD] -0.69, 95%CI -1.93 to 0.56 units). Trials

    Full Text Available Abstract Background Cisplatin is widely used as an antineoplastic agent since it is effective against a broad spectrum of different tumours. Nevertheless, it has several potential side effects affecting different organ systems and an overdose may lead to life-threatening complications and even death. Case presentation We report on a 46-year old woman with non-small cell lung cancer who accidentally received 225 mg/m2 of cisplatin, which was threefold the dose as scheduled, within a 3-day period. Two days later, the patient presented with hearing loss, severe nausea and vomiting, acute renal failure as well as elevated liver enzymes. In addition, she developed a severe myelodepression. After plasmapheresis on two consecutive days and vigorous supportive treatment, the toxicity-related symptoms improved and the patient recovered without any sequelae. Conclusion To date, no general accepted guidelines for the treatment of cisplatin overdoses are available. Along with the experience from other published cases, our report shows that plasmapheresis is capable of lowering cisplatin plasma and serum levels efficiently. Therefore, plasma exchange performed as soon as possible can ameliorate all side effects of a cisplatin overdose and be a potential tool for clinicians for treatment. However, additional intensive supportive treatment-modalities are necessary to control all occurring side effects.

A further complication of the apheresis issue is represented by the indication of sepsis with multi organ dysfunction syndrome (MODS as the most common cause of death in patients in non-coronary intensive care units. Presently, an effective treatment to reduce mortality in sepsis and MODS patients is still not available. Therapeutic PEX in the management of sepsis and MODS was suggested several years ago and more recently (7, 8. On the other side, even a selective LA technique such as Heparin induced Extracorporeal Lipoprotein Precipitation (H.E.L.P. was used in the treatment of sepsis and it is still on use (9. In conclusion, extracorporeal therapeutic techniques can be clinically helpful in emergency, in deferred urgency and in chronic, long-term use. As these techniques are invasive and relatively complex, appropriate equipment and highly skillful medical and non-medical staff personnel is a necessary complement.   Key words: Therapeutic Plasmapheresis, Plasma Exchange, Lipoprotein Apheresis, Hyperlipidemic Pancreatitis, Acute Pancreatitis, Homozygous- Heterozygous Familial Hypercholesterolemia, Hyper Lp(a lipoproteinemia

    Plasmapheresis (PP) is widely known as the standard therapy for thrombotic thrombocytopenic purpura (TTP). Citrate is used as an anticoagulant in fresh frozen plasma, and the large amount of citrate infused during PP induces metabolic alkalosis. A 29-year-old woman was diagnosed with TTP associated with systemic lupus erythematosus, and was treated by daily PP in addition to a steroid, an immunosuppressant, vincristine, and cyclophosphamide. Uncompensated alkalosis caused by a combination of metabolic and respiratory alkalosis developed after artificial ventilation was discontinued. Her metabolic status improved after controlling her respiratory status and the activity of the TTP. Metabolic alkalosis is a common complication in TTP patients treated by frequent PP, but several factors that affect metabolic status may aggravate the alkalosis and induce uncompensated alkalosis.

    Full Text Available BackgroundHashimoto’s encephalopathy (HE is a rare immunological neuropsychiatric disorder characterized by increased antithyroid antibodies and mixed neurological and psychiatric symptoms. HE has been previously discussed as a differential diagnosis for rapid progressive dementia. However, most of these patients suffered from additional neurological symptoms, like ataxia or seizures.Case presentationHere, we present the case of a 59-year-old female patient suffering rapid onset dementia with salient frontal executive dysfunction. She developed rapid onset symptoms, including apathy, verbal depletion up to a stuporous state, severe working memory deficits, evidence of primitive reflexes, disturbed Luria’s three-step test, and micturition disorder. Analysis of her cerebrospinal fluid was normal. The serum analyses showed increased antithyroid (antithyroid peroxidase and antithyroglobulin antibodies. In the cerebral magnetic resonance imaging, supratentorial deep and peripheral white matter lesions were found; the electroencephalography showed intermittent slowing, and the [18F]fluorodeoxyglucose positron emission tomography (FDG-PET depicted medial and superior dorsolateral frontal hypometabolism. Several different psychopharmacological therapeutic approaches with various neuroleptics, antidepressants, and high doses of lorazepam were unsuccessful. Due to the organic alterations, including increased antithyroid antibodies, HE was suspected. Against expectations, treatment with high-dose corticosteroids proved to be ineffective and was associated with worsening symptoms. However, escalated treatment with plasmapheresis over 5 days led to significant improvement in all reported symptoms and in psychometric testing. The neuropsychological improvement was stable over a 6-month follow-up period, and the FDG-PET normalized.ConclusionThis case report reveals that (1 HE can mimic rapid onset dementia with predominantly frontal dysfunction; (2 this

    Full Text Available A 26-year-old man highly suspected of having antiglomerular basement membrane (GBM disease was treated with corticosteroid pulse therapy 9 days after initial infection-like symptoms with high procalcitonin value. The patient required hemodialysis the next day of the treatment due to oliguria. In addition to corticosteroid therapy, plasmapheresis was introduced and the patient could discontinue hemodialysis 43 days after the treatment. Kidney biopsy after initiation of hemodialysis confirmed anti-GBM disease with 86.3% crescent formation. Physician should keep in mind that active anti-GBM disease shows even high procalcitonin value in the absence of infection. To pursue recovery of renal function, the challenge of the immediate and persistent treatment with high-dose corticosteroids plus plasmapheresis for highly suspected anti-GBM disease is vitally important despite the presence of reported predictors for dialysis-dependence including oliguria and requiring hemodialysis at presentation.

    To present a case of nonparaneoplastic autoimmune retinopathy in association with myasthenia gravis in a young woman, and to report the effect of plasmapheresis as well as passage of antiretinal antibodies through the placenta. Case report. A 31-year-old woman presented with a history of myasthenia gravis and rapidly progressive vision loss at the age of 23. Funduscopic appearance and fluorescein angiographic findings on presentation were consistent with an autoimmune retinopathy. Paraneoplastic etiology was ruled out, and antiretinal antibody testing revealed positivity for autoantibodies against GAPDH, aldolase, enolase, arrestin, as well as unnamed 48-kDa and 60-kDa proteins. ARA Western Blot and immunohistochemistry profiles were unchanged by either plasmapheresis therapy or passage of serum through the maternal placenta. However, the patient's 6-month and 8-year-old daughters appeared unaffected. This is the first report of nonparaneoplastic autoimmune retinopathy associated with myasthenia gravis, although a strong history of autoimmune disorders is a known risk factor. Our patient's antiretinal antibody panel was unaffected immediately after plasmapheresis treatment. Antibodies to GAPDH and unnamed 38-kDa and 86-kDa proteins were able to pass through the placenta into the fetal circulation, although their effect on the growing fetus is not clear.

    In acute liver failure (ALF), urea production is severely impaired, and detoxification of ammonia by glutamine synthesis plays an important protective role. The aim of this study was to examine the effects of therapeutic high-volume plasmapheresis (HVP) on arterial concentrations and splanchnic exchange rates of ammonia, urea, and amino acids-in particular, glutamine. A quantity of 8 L of plasma was exchanged over the course of 7 h in 11 patients with ALF after development of hepatic encephalopathy grade III-IV. Splanchnic exchange rates of ammonia, urea, and amino acids were measured by use of liver vein catheterization. HVP removed ammonia and glutamine at a rate of 1 micromol/min and 27 micromol/min, respectively. Arterial ammonia decreased from 160 +/- 65 to 114 +/- 50 micromol/L (p HVP) were as follows: for ammonia, -93 +/- 101 versus -70 +/- 80 micromol/min (NS); urea-nitrogen, 0.08 +/- 1.64 versus -0.31 +/- 0.45 mmol/min (NS); alanine, -73 +/- 151 versus 12 +/- 83 micromol/min (p HVP in patients with ALF. The data suggest that this effect of HVP could be explained by increased hepatic urea synthesis and possibly by increased glutamine synthesis in muscle tissue.

To assess the impact of plasmapheresis on the time course of changes in pro- and anti-inflammatory interleukins and the results of treatment in patients after complicated operations on the heart and great vessels.Material and methods. 44 patients were examined. In 33 patients, the intra- and postoperative period was complicated by a prolonged extracorporeal circulation (EC, massive blood loss, acute hemolysis, the development of disseminated intravascular coagulation. The above complications gave grounds to perform plasmapheresis (PA in different postoperative periods. The patients were equally divided into 4 groups (each containing 11 patients: 1 patients with multiple organ dysfunction (MOD, in whom PA was conducted within 2—6 hours after surgery; 2 those without MOD, in whom PA was also performed within 2—6 hours after surgery; 3 those with MOD in whom PA was made 16-20 hours after surgery; 4 a control group (receiving no PA, the early postoperative period was normal. Interleukins (IL 6, 8, and 10 and the oxygenation index (OI after surgery and in the first 24 postoperative hours, the duration of EC, the volume of blood loss, and a postoperative clinical period were studied.Results. The duration of EC was highest in Group 1 patients and 37 and 130% greater in Groups 2 and 3, respectively. The elevated levels of IL-6 were noted in all the patients. In the early post-PA periods, the content of IL-6 was decreased by 30% in Groups 1 and 2 patients. In Group 3, the level of IL-6 remained unchanged within the first 24 hours. The postoperative concentration of IL-8 was increased in all the patients. There were no changes in the content of IL-8 after surgery and within the first 12 hours. In Group 3 patients, the level of IL-8 within the first 24 hours was 5 times higher than that observed just after surgery. In patients with developed MOD, a correlation was found between IL-8 and OI postoperatively and within the first 24 hours after

    Liver failure represents a major therapeutic challenge, and yet basic pathophysiological questions about hepatic perfusion and oxygenation in this condition have been poorly investigated. In this study, hepatic blood flow (HBF) and splanchnic oxygen delivery (DO2, sp) and oxygen consumption (VO2,sp) were assessed in patients with liver failure defined as hepatic encephalopathy grade II or more. Measurements were repeated after high-volume plasmapheresis (HVP) with exchange of 8 to 10 L of plasma. HBF was estimated by use of constant infusion of D-sorbitol and calculated according to Fick's principle from peripheral artery and hepatic vein concentrations. In 14 patients with acute liver failure (ALF), HBF (1.78 +/- 0.78 L/min) and VO2,sp (3.9 +/- 0.9 mmol/min) were higher than in 11 patients without liver disease (1.07 +/- 0.19 L/min, P HVP, HBF increased from 1.67 +/- 0.72 to 2.07 +/- 1.11 L/min (n=11) in ALF, and from 1.89 +/- 1.32 to 2.34 +/- 1.54 L/min (n=7) in AOCLD, P HVP. Blood flow was redirected to the liver as the systemic vascular resistance index increased (1,587 +/- 650 vs. 2, 020 +/- 806 Dyne. s. cm-5. m2, P HVP, but as cardiac output increased from 9.1 +/- 2.8 to 10.1 +/- 2.9 L/min (P HVP (n=18), DO2,sp increased by 15% (P HVP. Changes of ET-1 were positively correlated with changes in HBF (P HVP (P HVP did not correlate. Our data suggest that liver failure is associated with increased HBF and VO2, sp. HVP further increased HBF and DO2,sp but VO2,sp was unchanged, indicating that splanchnic hypoxia was not present.

    Full Text Available Posttransplant antiglomerular basement membrane (anti-GBM disease occurs in approximately 5% of Alport patients and usually ends in irreversible graft failure. Recent research has focused on characterizing the structure of the anti-GBM alloepitope. Here we present a case of a 22-year-old male with end-stage renal disease secondary to Alport syndrome, with a previously failed renal allograft, who received a second deceased-donor kidney transplant. Six days after transplantation, he developed acute kidney injury. The serum anti-GBM IgG was negative by enzyme immunoassay (EIA. On biopsy, he had crescentic glomerulonephritis with linear GBM fixation of IgG. With further analysis by western blotting, we were able to detect antibodies to an unidentified protein from the basement membrane. This patient was treated with plasmapheresis twice per week and monthly intravenous immunoglobulin (IVIG for a total of five months. At the end of treatment, these unknown antibodies were no longer detected. His renal function improved, and he has not required dialysis. We conclude that anti-GBM disease in patients with Alport Syndrome may be caused by circulating antibodies to other components of the basement membrane that are undetectable by routine anti-GBM EIA and may respond to treatment with plasmapheresis and IVIG.

    Full Text Available To study the effects of plasmapheresis in preparation for thymectomy, two groups of 40 patients were selected from a sample of 286 patients with myasthenia gravis examined by the first author Group 1 included patients (15 male and 25 female; age range 8-64 yrs who underwent thymectomy without previous plasmapheresis, whereas patients in group 2 (17 male and 23 female; age range 11-61 yrs were thymectomized after plasmapheresis. We required patients to have a minimum follow-up period of 12 months to be included in the study. A clinical evaluation protocol composed of 76 items was developed for the study. We found significant improvement in respiratory function and muscular strength in patients thymetomized after plasmapheresis. Furthermore, the combined treatment reduced cost and length of hospital stay. Therefore, we conclude that plasmapheresis should be considered as a coadjuvant to thymectomy in the treatment of myasthenia gravis.No intuito de estudar as repercussões de um curso de plasmaferese como método preparatório para a timectomia, tomamos duas amostras de 40 pacientes selecionados de um universo de 286 casos de miastenia gravis, em que a investigação clínica, eletrofisiológica, laboratorial, o seguimento e o protocolo foram completamente realizados. Consideramos como grupo 1 aquele em que a timectomia foi realizada sem preparação pre-operatória e grupo 2 aquele em que a plasmaferese foi executada como coadjuvante a timectomia. O grupo 1 era composto de 15 pacientes do sexo masculino e 25 do feminino; a idade variou de 8 a 64 anos com mediana de 30 anos.

    Full Text Available Background. High-dose IVIG (2 g/kg alone or low-dose IVIG (100 mg/kg in conjunction with plasma exchange is typically administered as a renal transplantation desensitization therapy. Herein, we monitored changes in T cell and B cell flow cytometry crossmatch (FCXM to assess the effects of short-term super high-dose IVIG (4 g/kg administration with plasmapheresis before living-donor renal transplantation. Methods. Seventeen patients, each showing positive T cell FCXM (median ratio, ≥ 1.4 after 2 rounds of double-filtration plasmapheresis, received 4-day regimens of IVIG (1 g/kg per day over 1-week periods. T cell and B cell FCXM determinations were obtained after every IVIG dose and again up to 4 weeks after initiating IVIG to ascertain negative conversion of T cell FCXM (median ratio < 1.4. The primary study endpoint was the percentage of patients achieving T cell FCXM-negative status after the 4-dose IVIG regimen. Results. Upon completion (4 g/kg total or discontinuation of IVIG administration, 8 (47.1% of 17 patients displayed negative T cell FCXM. Based on Kaplan-Meier estimates, the cumulative T cell FCXM-negative conversion rate 4 weeks after IVIG administration initiation was 60.3%. The T cell FCXM-negative conversion rates after cumulative doses of 1, 2, 3, and 4 g/kg IVIG were 29.4%, 35.3%, 56.3%, and 46.7%, respectively. Conclusions. Desensitization of donor-specific antibody-positive renal transplant recipients seems achievable in only a subset of recipients through IVIG dosing (1 g/kg × 4 within 1 week after double-filtration plasmapheresis. The T cell FCXM-negative conversion rate resulting from a cumulative IVIG dose of 3 g/kg or greater surpassed that attained via conventional single-dose IVIG (2 g/kg protocol. This short-term high-dose IVIG desensitization protocol may be an alternative to conventional protocols for recipients with donor-specific antibody.

    Blood group incompatibility in kidney transplants from a living donor can be successfully overcome by using various desensitization protocols: intravenous immunoglobulin, plasmapheresis (PP), immunoadsorption, and double filtration PP. From July 2010 to October 2013, we performed 10 ABO incompatible kidney transplantation (KT) procedures from a living donor. The desensitization protocol was based on rituximab and PP+cytomegalovirus immune globulin. All patients received induction with basiliximab, except 1 case treated with Thymoglobuline® (ATG) for the simultaneous presence of donor-specific antibody. Tacrolimus and mycophenolate mofetil were initiated at the time of desensitization and continued after the transplant. After a mean follow-up of 11.6±10.4 months, all patients are alive with a functioning graft. The mean serum creatinine concentration at 1 month, 3 months, 6 months, and 1 year was 1.48±0.29, 1.47±0.18, 1.47±0.27, and 1.5±0.27 mg/dl. Three episodes of acute cellular rejection occurred in 2 patients. There was only 1 case of BK virus infection, treated with reduction of immunosuppressive therapy. The protocol biopsy specimens at 1, 3, and 6 months were C4d positive in the absence of acute rejection. Desensitization with rituximab, PP, and anti-cytomegalovirus immune globulin allowed us to perform transplants from living donors to ABO incompatible recipients with excellent results and reduced costs.

    Asparaginase-associated concurrence of hyperlipidemia, hyperglobulinemia, and thrombocytosis is a rare complication requiring aggressive lipoprotein apheresis, but no one of currently available lipoprotein apheresis methods can simultaneously resolve the 3 abnormalities. Herein, we reported a construction of double-filtration plasmapheresis (DFPP) using a combination of centrifugal/membranous plasma separation techniques to successfully treat a patient with hyperlipidemia, hyperglobulinemia, and thrombocytosis. A male presented with severe hyperlipidemia, hyperglobulinemia, and thrombocytosis during asparaginase treatment for NK/T-cell lymphoblastic lymphoma and was scheduled to receive lipoprotein apheresis. To simultaneously remove lipoproteins, immunoglobulin, and deplete platelets from blood, a centrifuge/membrane hybrid DFPP was constructed as following steps: plasma and part of platelets were separated first from whole blood by centrifugal technique and then divided by a fraction plasma separator into 2 parts: platelets and plasma components with large size, which were discarded; and those containing albumin, which were returned to blood with a supplement of extrinsic albumin solution. DFPP lasted 240 minutes uneventfully, processing 5450-mL plasma. The concentrations of plasma components before DFPP were as follows: triglycerides 38.22 mmol/L, total cholesterols 22.98 mmol/L, immunoglobulin A (IgA) 15.7 g/L, IgG 12.7 g/L, and IgM 14.3 g/L; whereas after treatment were 5.69 mmol/L, 2.38 mmol/L, 2.5 g/L, 7.7 g/L, and 0.4 g/L, respectively. The respective reduction ratio was 85.1%, 89.6%, 83.9%, 39.4%, and 96.9%. Platelet count decreased by 40.4% (from 612 × 10(9)/L to 365 × 10(9)/L). Centrifuge/membrane hybrid DFPP can simultaneously remove lipoproteins, immunoglobulin, and deplete platelets, with a success in treatment of asparaginase treatment-induced hyperlipidemia, hyperglobulinemia, and thrombocytosis, and may be useful for patients

    Full Text Available In 1960's, with succesfully renal transplantations, acute rejection became to be a serious problem for graft survival. From 1965 to 2010, with the introduction of new immunosuppressant agents such as cyclosporine, mycophenolate mofetile and tacrolimus, the acute rejection rates declined from 80% to 10% . There is an ongoing gradual improvement in allograft survival. Use of Therapeutic plasma exchange (TPE is not evidence based treatment, but TPE is necessary for pre- and also post transplantation in patients with DSA. TPE is also a main treatment for antibody mediated rejection (AMR , but in clinical practice the duration and frequency of TPE and individual difference of antibody production is unclear. There is a requirement for more specific antibody elimination. Further randomised controlled studies are needed to elucidate TPE use before and after kidney transplantation.

    In December 2017, 79 delegates attended the 2nd regional plasmapheresis conference and workshop for Southeast Asia (SEA) on the immunomodulatory role of plasma exchange in central and peripheral nervous system disorders in Kuala Lumpur, Malaysia. This meeting featured 6 plenary lectures, interactive sessions dedicated for experience sharing, case presentations, and a practical session for paramedics. Clinical experts and researchers from 7 SEA countries and India shared experience and challenges in treating autoimmune neurological disorders. While the spectrum of diseases and neurology practice remained largely similar, there was great disparities in accessibility of therapeutic plasma exchange (TPE) within SEA countries and between urban or rural settings. Costs, human resources, and healthcare policies are common challenges in providing sustainable TPE services. Novel techniques and innovative ideas in performing TPE were explored. A working consortium comprising of key opinion leaders was proposed to improve standards of TPE and enhance future research. © 2018 Wiley Periodicals, Inc.

    Full Text Available La plasmaféresis terapéutica es un procedimiento extracorpóreo en el que, a partir de la extracción de sangre total, se separa el plasma del resto de los componentes celulares con el objetivo de disminuir o eliminar determinadas sustancias patológicas que intervienen en la fisiopatología de la enfermedad. En la actualidad, es el procedimiento de aféresis más frecuentemente usado en la medicina clínica. Se mencionan los avances fundamentales en sus indicaciones, métodos y soluciones de reposición, y se evalúan las indicaciones de plasmaféresis realizadas en el Instituto de Hematología e Inmunología en el período comprendido entre enero de 2009 y diciembre de 2010. Se evaluaron 295 plasmaféresis realizadas a 35 pacientes con 9 enfermedades o condiciones asociadas con ellas; el 60 % correspondieron con la categoría I de la Asociación Americana de Aféresis (ASFA y el proceder mostró efectividad en el 88,6 % de los casos. El volumen de recambio osciló entre 750 y 2 400 mL y la solución de reposición más empleada fue la solución salina, seguida del plasma fresco congelado y la albúmina. En el 4,06 % de los casos se evidenció alguna reacción adversa relacionada con el proceder, pero estas fueron leves y de fácil control.

    Hypertriglyceridemia can cause severe diseases such as acute pancreatitis (AP) and coronary artery disease. The routine management of hypertriglyceridemia is dietary restriction of fat and lipid-lowering medications to manage the secondary or precipitating causes of hypertriglyceridemia. However, in cases of AP with severe hypertriglyceridemia (SHTG) (triglycerides [TG] >1000 mg/dl) rapid reduction of TG levels to well below 1000 mg/dl can improve outcome and prevent further episodes of pancr...

    The goal of this project was to study the feasibility of using a DNA-immobilized nanocellulose-based immunoadsorbent for possible application in medical apheresis such as systemic lupus erythematosus (SLE) treatment. Calf thymus DNA was bound to high surface area nanocellulose membrane at varying concentrations using UV-irradiation. The DNA-immobilized samples were characterized with scanning electron microscopy, atomic force microscopy, and phosphorus elemental analysis. The anti-ds-DNA IgG binding was tested in vitro using ELISA. The produced sample showed high affinity in vitro to bind anti-ds-DNA-antibodies from mice, as much as 80% of added IgG was bound by the membrane. Furthermore, the binding efficiency was quantitatively dependent on the amount of immobilized DNA onto nanocellulose membrane. The described nanocellulose membranes are interesting immunoadsorbents for continued clinical studies. Copyright © 2016 Elsevier B.V. All rights reserved.

    A correlation exists between polyomavirus BK (BKV) viremia in renal transplant recipients (RTR) and the degree of immunosuppression. However, the impact of pre-transplant desensitization on the incidence of BKV viremia is unknown. This retrospective study evaluated living-donor RTR between January 2004 and December 2008 receiving routine BKV viral load monitoring. Patients were divided into those who underwent pre-transplant desensitization (n = 20) and those who did not (n = 71). The primary endpoint was the incidence of BKV viremia at 1 year post transplant. All demographic data were similar, except for more female patients (65% vs. 36.6%; P = 0.0392) in the desensitized group. More desensitized patients had a previous transplant (75% vs. 12.7%; P < 0.0001) and were more likely to be induced with basiliximab (75% vs. 35.2%; P = 0.0021). Following transplantation, antibody-mediated rejection (AMR) rates were highest in the desensitized group (55% vs. 1.4%; P < 0.0001). The incidence of BKV viremia at 1 year post transplant was significantly higher in desensitized patients (45% vs. 19.7%; P = 0.0385). Desensitization was also associated with a higher prevalence of BKV viremia at any time post transplant (50% vs. 22.5%; P = 0.0245), polyomavirus-associated nephropathy (20% vs. 2.8%; P = 0.0198) and BKV-related allograft loss (10% vs. 0%; P = 0.0464). Also of note, in a subgroup analysis of only our desensitized patients, it did not appear that development of AMR significantly impacted the incidence of BKV viremia in these individuals. This analysis reveals that pre-transplant desensitization significantly increases the risk for BKV viremia and nephropathy. © 2013 John Wiley & Sons A/S.

    There is a need of comprehensive work dealing with the quality of plasma for fractionation with respect to the IgG content as today most plasma derivates are used to treat patients with immunodeficiencies and autoimmune disorders. Therefore, a prospective study was carried out to analyse IgG levels before plasmapheresis and every 200ml collected plasma. Fifty-four experienced plasmapheresis donors were recruited for subsequent 850ml plasmapheresis using the Aurora Plasmapheresis System. Donorś peripheral blood counts were analysed before and after plasmapheresis using an electronic counter. Total protein, IgG and citrate were measured turbidometrically before, during and after apheresis as well as in the plasma product. Furthermore, platelets, red and white blood cells were analysed as parameters of product quality. An average of 2751±247ml blood was processed in 47±6min. The collected plasma volume was 850±1mL and citrate consumption was 177±15mL. A continuous drop of donors' IgG level was observed during plasmapheresis. The drop was 13% of the IgG baseline value at 800mL collected plasma. Total protein, IgG and cell counts of the plasma product met current guidelines of plasma for fractionation. Donors' IgG levels during apheresis showed a steady decrease without compromising the quality of plasma product. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Paraneoplastic melanocytic proliferation (bilateral diffuse uveal melanocytic proliferation, BDUMP) is a rare but devastating disease that causes progressive visual loss in patients who usually have an occult malignancy. Visual loss occurs as a result of paraneoplastic changes in the uveal tissue. In a masked fashion, the serum of two patients with BDUMP was evaluated for the presence of cultured melanocyte elongation and proliferation (CMEP) factor using cultured human melanocytes. We evaluated the efficacy of plasmapheresis as a treatment modality early in the disease in conjunction with radiation and chemotherapy. The serum of the first case patient was investigated after plasmapheresis and did not demonstrate proliferation of cultured human melanocytes. The serum of the second case was evaluated prior to treatment with plasmapheresis and did induce this proliferation. These findings are in accordance with the diminution of CMEP factor after plasmapheresis. Treatment with plasmapheresis managed to stabilise the ocular disease progression in both patients. In the past, visual loss due to paraneoplastic melanocytic proliferation was considered progressive and irreversible. We treated two patients successfully with plasmapheresis and demonstrated a relation between CMEP factor in the serum of these patients and proliferation of cultured melanocytes.

    Full Text Available The main problem of severe bacterial infections intensive therapy in children is toxemia, disorder of hemodynamic and oxygen transport. Aim. The aim of the work was to study the features of hemodynamics, oxygen transport, the level of toxemia during bacterial intoxication treatment in children, including discrete plasmapheresis. Methods and results. The study included 28 children with severe bacterial infections. We found that the inclusion of efferent methods of intensive care, such as a discrete plasmapheresis, helped to reduce circulation hyperdynamia and restore a balanced mode of delivery and oxygen consumption within 24 hours after the plasmapheresis session. Conclusion. Reduction of toxemia was noted after plasmapresis, which was confirmed by a significant decreasing in the toxicity markers level – middle molecules in the blood and leukocyte index of intoxication.

    2014-07-01

    Hashimoto encephalopathy is a steroid-responsive encephalopathy associated with elevated titers of antithyroid antibodies. Clinical symptoms are characterized by behavioral and cognitive changes, speech disturbance, seizures, myoclonus, psychosis, hallucination, involuntary movements, cerebellar signs, and coma. The standard treatment is the use of corticosteroids along with the treatment of any concurrent dysthyroidism. Other options are immunoglobulins and plasmapheresis. We described symptoms and outcomes on 3 teenage girls with Hashimoto encephalopathy. Presenting symptoms were seizure or altered mental status. One patient took levothyroxine due to hypothyroidism before presentation of Hashimoto encephalopathy. After confirmation of elevated antithyroid antibodies, all patients were treated with steroids. One patient needed plasmapheresis because of the lack of response to steroids and immunoglobulins. Hashimoto encephalopathy should be considered in any patient presenting with acute or subacute unexplained encephalopathy and seizures. Even though the use of steroids is the first line of treatment, plasmapheresis can rescue steroid-resistant patients. © The Author(s) 2013.

    Full Text Available Objective: to improve the results of victims with massive crushes of soft tissues in severe concomitant injury (SCI, by applying extracorporeal detoxification techniques as soon as possible. Subjects and methods. The results of examination and treatment were studied in 41 victims with SCI treated at the N. N. Burdenko Main Military Clinical Hospital in 2006 to 2008. In the early posttraumatic period (on days 1—3, all the victims (n=41 were divided into 2 groups. Group 1 victims (n=19 underwent hemodiafiltration (HDF with replacement at 35 ml/kg/hr; Group 2 (n=22 had plasmapheresis. Results. Early HDF applied to Group 1 victims could achieve 32, 44, and 37% reductions in the elevated levels creatine phosphokinase, myoglobin, and middle-sized molecules, respectively. In Group 2, plasmapheresis showed a lower effect (19, 25, and 26% reductions. Furthermore, there was a decrease in total protein in Group 1, which was absent in Group 2. Conclusion. The timely use of extracorporeal detoxification techniques in victims with massive crushes of soft tissues in the early posttraumatic period prevents the development of fatal complications of SCI, at the same time HDF is more effective and safe than plasmapheresis. Key words: severe concomitant injury, rhabdomyolysis, myoglobin, plasmapheresis, hemodiafiltration.

    Antibody-mediated anti-glomerular basement membrane (anti-GBM) disease occurs rarely in the presence of another B-cell disorder, membranous nephropathy. The coexistence of these two autoimmune disorders would be anticipated to require differing, specific therapies targeted to each disease process. We describe a case of concomitant membranous nephropathy and anti-GBM disease in which conventional therapy, including steroids, plasmapheresis and cyclophosphamide, failed to attenuate the anti-GBM disease, yet responded to an alternative treatment of rituximab. This B-cell directed, monoclonal, chimeric antibody treatment substantially reduced anti-GBM antibody titers and led to discontinuation of plasmapheresis, while maintaining the remission of membranous nephropathy and anti-GBM disease.

    We describe a case of a 47 years old male, with a history of 2 days of progressive, ascendant, symmetrical weakness in the lower extremities; a lumbar puncture was performed after the brain CT scan, as well as an electromyography, evidencing pure motor polyradiculopathy with axonal pattern, compatible with Guillain Barre syndrome. Afterwards, he received four plasmapheresis sessions, with clinical improvement from the second session. Due to his epidemiological background, Brucella set testing was done. Rose Bengal was positive, antibiotic treatment with rifampin and doxicicline was initiated, as well as rehabilitation. Three months later the patient recovered completely. The relevance of early treatment with plasmapheresis and the definition of the etiologic diagnosis determine that the prognosis of the Guillain Barre syndrome is favorable.

    Full Text Available Acute hemorrhagic leukoencephalitis (AHLE is a rare demyelinating disease characterized by an acute rapidly progressive fulminant inflammation of the white matter. In this case report, we introduce a case of AHLE in children with an interesting and lengthy process and successful treatment. A previously healthy 13-year-old girl was admitted to the hospital because of fever and loss of consciousness. After 4 days, she was referred to our pediatric intensive care unit in Mashhad, Iran. On admission, she had right-sided parotiditis. With a diagnosis of AHLE, our patient was treated with methylprednisolone, intravenous immunoglobulin, acyclovir, and plasmapheresis. AHLE is a rare and severe demyelinating disease, the mortality and morbidity of which can be decreased by early detection and treatment with steroid therapy, intravenous immunoglobulin, acyclovir, and plasmapheresis.

    2015-01-01

    Central nervous system complications of bone marrow transplant are a common occurrence and the differential diagnosis is quite broad, including opportunistic infections, medications toxicities, graft versus host disease, and other autoimmune processes. We summarize previously reported cases of autoimmune myelitis in post-transplant patients and discuss a 17-year-old boy who presented with seronegative neuromyelitis optica after a bone marrow transplant for acute myeloid leukemia. Our patient had a marked improvement in symptoms after plasmapheresis. Including our patient, there have been at least eight cases of post-transplant autoimmune myelitis presented in the literature, and at least three of these are suspicious for neuromyelitis optica. Several of these patients had poor outcomes with persistent symptoms after the myelitis. Autoimmune processes such as neuromyelitis optica should be carefully considered in patients after transplant as aggressive treatment like early plasmapheresis may improve outcomes.

    2011-01-01

    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. 

  7. Hypertriglyceridemia: Is there a role for prophylactic apheresis? A case report

    Directory of Open Access Journals (Sweden)

    Ana Rita Francisco

    Full Text Available Abstract Severe hypertriglyceridemia has been consistently associated with an increased risk of cardiovascular disease and other complications, namely acute pancreatitis. We report a case of a 64 year-old woman with hypertrophic cardiomyopathy and metabolic syndrome with triglyceride level of 3260 mg/dL. Plasma exchange was performed with simultaneous medical treatment to achieve a rapid and effective lowering of triglycerides in order to prevent clinical complications. After three plasmapheresis sessions a marked reduction in triglyceride and total cholesterol levels was observed. Several cases have shown the importance of plasmapheresis in the treatment of acute pancreatitis. We intend to demonstrate the applicability of this technique as primary prophylaxis in the presence of extremely high serum triglyceridemia levels.

A 14-year-old girl with type 1 diabetes mellitus presented with recurrent hypoglycemia. High insulin, low C-peptide and raised insulin antibody levels documented during hypoglycemia. Plasmapheresis led to remission of hypoglycemia. Antibodies to exogenous insulin should be considered as a cause of recurrent refractory hypoglycemia in type 1 diabetes mellitus patients.

    During pregnancy, a progressive increase in serum triglyceride (TG) and cholesterol levels is observed whereas TG levels mostly remain hypertriglyceridemia, pregnancy may cause extremely elevated TG levels leading to potentially life-threatening pancreatitis attacks and chylomicronemia syndrome. The only safe medical treatment option during pregnancy is ω-3 fatty acids, which have moderate TG lowering effects. Therapeutic apheresis could be used as primary treatment approach during pregnancy. We reported the effect of double filtration apheresis in one pregnant women with severe hypertriglyceridemia, therapeutic plasmapheresis and double filtration methods in the other severe hypertriglyceridemic pregnant woman; a 32-year-old pregnant woman (patient 1) with a history of hypertriglyceridemia-induced acute pancreatitis during pregnancy and a 30-year-old pregnant woman with extremely high TG levels (12,000 mg/dl) leading to chylomicronemia syndrome (patient 2). Medical nutrition therapy and ω-3 fatty acids were also provided. Double filtration apheresis (patient 1) and plasmapheresis + double filtration apheresis (patient 2) were used. When we calculated the TG levels before and after therapeutic apheresis, maximum decrease achieved with double filtration apheresis was 46.3 % for patient 1 and 37.3 % for patient 2. However, with plasmapheresis TG level declined by 72 % in patient 2. Plasmapheresis seemed to be more efficient to decrease TG levels. Iron deficiency anemia was the main complication apart from technical difficulties by lipemic obstruction of tubing system. Healthy babies were born. Delivery led to decreases in TG levels. It is concluded that during pregnancy therapeutic apheresis is an effective method to decrease extremely high TG levels and risks of its potentially life-threatening complications.

    Plasmapheresis is a well-accepted treatment option in severe hypertriglyceridemia-induced pancreatitis (HTGP). The rationale behind this approach is the depletion of triglycerides and the reduction of inflammatory cytokines. The time span between onset of clinical symptoms and start of plasmapheresis might have an important impact on mortality. Hyperviscosity of patients' plasma represents another special challenge for the applied separation technology. The procedures can be performed either by centrifugal device (CFD) or membrane based (MBS) units. The present study reports the outcome of 10 patients suffering from HTG. The expected mortality of the collective was 25%. Plasmapheresis was started after an average 16.3 h (SD ± 6.7 h) after onset of symptoms. No mortality occurred. Apheresis was statistically equally effective with both devices. A median of 3 sessions reduced the TG level to normal and correlated with patients' improvement. During follow up, three patients developed a pancreatic pseudocyst requiring surgical intervention without further complication. © 2015 The Authors.

    2017-01-01

    Full Text Available Introduction. Acquired thrombotic thrombocytopenic purpura (TTP has been associated with different autoimmune disorders. However, its association with pernicious anemia is rarely reported. Case Report. A 46-year-old male presented with blood in sputum and urine for one day. The vitals were stable. The physical examination was significant for icterus. Lab tests’ results revealed leukocytosis, macrocytic anemia, severe thrombocytopenia, renal dysfunction, and unconjugated hyperbilirubinemia. He had an elevated LDH, low haptoglobin levels with many schistocytes, nucleated RBCs, and reticulocytes on peripheral smear. Low ADAMTS13 activity (<10% with elevated ADAMTS13 antibody clinched the diagnosis of severe acquired TTP, and plasmapheresis was started. There was an initial improvement in his hematological markers, which were however not sustained on discontinuation of plasmapheresis. For his refractory TTP, he was resumed on daily plasmapheresis and Rituximab was started. Furthermore, the initial serum Vitamin B12 and reticulocyte index were low in the presence of anti-intrinsic factor antibody. So with the concomitant diagnosis of pernicious anemia, Vitamin B12 was supplemented. The rest of the immunological workups were negative. Subsequently, his symptoms resolved and his hematological parameters improved. Discussion. While pernicious anemia can masquerade as TTP, an actual association between the two can also occur and needs further evaluation and characterization.

    Full Text Available Severe hemolysis was observed in a critically ill patient with G6Pd deficiency where the causative trigger could not be identified. We describe one young patient with severe hemolysis treated with two cycles of plasmapheresis which proved to be an effective tool in the treatment. The patient presented with diffuse pain abdomen, vomiting, yellowish discoloration of sclera and skin and acute breathlessness. Hemoglobin 5.4 mg/dl and total (T serum bilirubin 17.08 mg/dl: Direct (D 4.10 mg/dl and Indirect (I 12.98 mg/dl. Subsequently patient started passing black color urine. As the patient developed severe hemolysis and the trigger agent of hemolysis was unknown, two cycles of plasmapheresis were performed with the aim to remove unknown causative agent. Consequently no trace of hemolysis was found and patient stabilized. Plasmapheresis can be used to treat G6PD deficient patients with severe hemolysis due to unidentified trigger agent.

  5. Antibody-Mediated Rejection of the Heart in the Setting of Autoimmune Demyelinating Polyneuropathy: A Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Kathryn J. Lindley

    2012-01-01

    Full Text Available Background. Antibody-mediated rejection (AMR is caused by the production of donor-specific antibodies (DSA which lead to allograft injury in part via complement activation. The inflammatory demyelinating polyneuropathies (IDP are inflammatory disorders of the nervous system, involving both cellular and humoral immune mechanisms directed against myelin. Case Report. A 58-year-old man five years after heart transplant presented with progressive dyspnea, imbalance, dysphagia, and weakness. Nerve conduction studies and electromyogram were consistent with IDP. Plasmapheresis and high-dose steroids resulted in improvement in neurologic symptoms. Within two weeks, he was readmitted with anasarca and acute renal failure, requiring intravenous furosemide and inotropic support. Echocardiogram and right heart catheterization revealed reduced cardiac function and elevated filling pressures. DSA was positive against HLA DR53, and endomyocardial biopsy revealed grade 1R chronic inflammation, with strong capillary endothelial immunostaining for C4d. Plasmapheresis and intravenous immunoglobulin (IVIG were initiated. His anasarca and renal failure subsequently resolved, echocardiogram showed improved function off inotropes, and anti-DR53 MFI was reduced by 57%. Conclusions. This is an example of a single immune-mediated process causing concurrent IDP and AMR. The improvement in cardiac function and neurologic symptoms with plasmapheresis, IVIG, and high-dose steroids argues for a unifying antibody-mediated mechanism.

    Donor vigilance is an important part of the quality management system of blood transfusion services. The evaluation of donor side effects helps to improve the donation process and donor compliance. The aim of the present study was to evaluate donor vigilance data in whole blood and plasmapheresis donors of a blood donor service. Donors fulfilling current national and European eligibility criteria underwent whole blood and plasmapheresis donation (PCS and MCS+ (Haemonetics, Braintree, USA), A 200 (Fenwal, Round Lake, USA). Whole blood was collected at fixed and mobile sites while plasmaphereses were performed at 8 plasma centers. From 2011 to 2013 donor information was provided for gender, age, body weight, height, first and repeat donation. Donors were monitored for venipuncture and circulatory associated side effects. The total incidences of adverse events were 5004 (0.56%) in repeat donors and 2111 (2.78%) in first time donors for whole blood donation and 3323 (1.01%) and 514 (7.96%) for plasmaphereses, respectively. Circulatory associated events were 2679 (0.30%) for whole blood donation and 1624 (0.49%) for plasmaphereses. Our donor vigilance data of a blood transfusion service show that whole blood and plasmapheresis are safe with low incidences of adverse events. Repeat donation and age are predictors for low rates of adverse events. On the other hand, first time donation and female gender were associated with higher incidences of adverse events.

    To determine whether a new desensitization protocol (mycophenolate mofetil [MMF], plasmapheresis and antithymocyte globulin [ATG], complemented with human leucocyte antigen [HLA] amino acid residue matching) could reduce panel-reactive antibody (PRA) levels in sensitized patients, to facilitate successful renal transplantation. Patients awaiting transplantation with PRA levels >10% received treatment with MMF; those with PRA levels >30% were also treated with plasmapheresis. Patients whose PRA level was desensitization were eligible for transplantation. When a donor became available, traditional HLA matching and HLA amino acid residue matching were performed. All patients received ATG induction therapy postoperatively. Thirty-two sensitized patients were enrolled. Desensitization produced a significant decrease in PRA levels; 27 patients (84.4%) became eligible for transplantation and 26 (81.2%) subsequently underwent successful transplantation. Residue matching improved the proportion with a mismatch number of 0-1 from 7.7% to 65.4%, compared with traditional HLA matching. Postoperatively, all patients showed immediate graft function. Acute rejection occurred in three patients (11.5%) and infections in seven patients (25.9%); all were treated successfully. The combination of a desensitization protocol (MMF, plasmapheresis and ATG) and residue matching appears to be an effective strategy for sensitized patients awaiting renal transplantation.

    Outcome data in paediatrics regarding the use of plasmapheresis for immunological kidney disease are scarce. We aimed to evaluate the role of plasmapheresis in children presenting with severe renal impairment secondary to immunological kidney diseases. A retrospective chart review of children admitted between January 2009 and August 2013 to the Paediatric Nephrology Unit, Christian Medical College, Vellore, India, and requiring plasma exchange was undertaken. Demographic and clinical data were studied and descriptive statistics applied for analysis. Sixteen children underwent plasmapheresis with a male:female ratio of 10:6 and a mean age of 10.2 years (range 5-15 years). Twelve children had atypical haemolytic uraemic syndrome, two had anti-glomerular basement disease and one each had lupus nephritis with neurological manifestation and anti-nuclear cytoplasmic antibody-associated vasculitis. The mean serum creatinine at presentation was 6.52 [interquartile range (IQR) 4.96-7.85] mg/dL with a mean eGFR of 43 (IQR 27.54-56.7) mL/min/1.73 m(2). Other presenting features included nephrotic range proteinuria (69%), gross haematuria (27%), hypertension (94%) and seizures (37.5%). All children received 1.5 times plasma volume plasmapheresis (mean 11 sessions, range 5-26), dialysis and immunosuppressive therapy. The mean duration of follow-up was 4 months (range 2-24 months) with a majority of the children (15/16, 93.75%) surviving acute illness. One child died of overwhelming sepsis and another was lost to follow-up. Of the survivors, eight had eGFR >60 mL/min/1.73 m(2), while eGFR was 15-60 mL/min/1.73 m(2) in the remaining six children. Eight children were still requiring antihypertensive medications and two were continuing peritoneal dialysis at the last follow-up. Thus early introduction of plasmapheresis along with other supportive therapy in immunological kidney disease may improve outcome.

    Full Text Available Effective selection of antibiotics in children with severe bacterial infections is often difficult because of microflora resistance. Extracorporeal detoxication methods, particularly discrete plasmapheresis are usually used for septic shock and total organ failure prevention. The aim of research. To conduct microbiological monitoring and to study a dynamics of medium molecular peptides in discrete plasmapheresis for intensive care optimization in children with severe bacterial infections in Anesthesiology and Intensive Care Department (AICU. Materials and methods. We investigated respiratory tract microflora by bacteriological method in 120 newborns and 30 children from 1 month with severe bacterial infections at admission and during prolonged stay in AICU. Discrete plasmapheresis was held in four children. Dynamic of medium molecular peptides was studied at admission, before discrete plasmapheresis and after it. Statistical data processing was performed using the Microsoft Excel software package. Results. It was found that in AICU in older children in admission grampositive and gramnegative flora was defined in equal quantity. The best sensitivity of the respiratory tract microflora was for the glycopeptides, oxazolidinones , II generation cephalosporins and macrolides, more than 60% - for aminoglycosides and lincosamides. However, when children spent more than 7-14 days in the department, nosocomial microflora was represented primarily by gram-negative organisms (80%, especially Pseudomonas aeruginosa. It was found to be inappropriate to use cephalosporins and macrolides in AICU for older children after their long stay there; the sensitivity to aminoglycosides was less than 60%, to anti-pseudomonal carbapenems not more than 30%. In AICU of newborns grampositive flora was found in 95%, mostly Staphylococcus haemolyticus. It was entirely sensitive for glycopeptides, oxazolidinones, fluoroquinolones, carbapenems, and also for co-trimoxazole and

    Anti-glomerular basement membrane (GBM) disease is a rare autoantibody-mediated disorder presenting as rapidly progressive glomerulonephritis, and often with pulmonary hemorrhage. Antibody removal with plasmapheresis and immunosuppressive drugs are the cornerstones of the treatment. Data regarding the use of specific B-cell depleting therapy such as rituximab are lacking. We conducted a retrospective observational study of 8 patients with severe and/or refractory GBM disease that received rituximab therapy. Eight patients (2 men, 6 women) with a mean age of 26 ± 13.1 years old were included. Seven had severe renal involvement [median creatinin level was 282 μmol/l, range (65-423)] requiring high immunosuppressive or plasmapheresis dependent, and two had relapse of pulmonary hemorrhage including one with renal failure. Patients received an initial immunosuppressive treatment including steroid and cyclosphosphamide (n = 8) and plasmapheresis (n = 5). Except one late relapse, rituximab therapy was started within two months after diagnosis. All patients except one received 4 weekly dose of rituximab (375 mg(2)). Anti-GBM antibodies were still present in 6/8 patients, at rituximab initiation. Complete remission was observed in 7 out of 8 patients, mostly 3 months after rituximab therapy. After a mean follow-up of 25.6 months (range 4-93), patient and renal survival were 100% and 75% respectively, but rituximab use did not improve GFR. Anti-GBM antibodies remained negative for all patients during follow-up. Only one patient developed a severe bacterial infection but no opportunistic or viral infections were reported. Rituximab may represent an additional and/or alternative therapy in the induction treatment of anti-GBM disease. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Introduction: Amiodarone as an antiarrhythmic medication is necessary in the prevention and treatment of malignant ventricular arrhythmias, however, it can induce thyroid dysfunction. Thyroid dysfunction may be either hypothyroidism or thyrotoxicosis, however, 50% of patients who have used amiodarone are euthyroid. Case report: A 27-year-old female patient, hospitalized at the Clinic for Endocrinology due to type 2 amiodarone-induced thyrotoxicosis. The patient had previously received amiodarone for two years. At age 25, the patient was diagnosed with dilated cardiomyopathy (EF 25%, EDD/ESD 56-57/47 mm with mild Ebstein’s anomaly, WPW Sy and recorded episodes of non-sustained VT. In order to reduce the risk of sudden death and prevent malignant ventricular arrhythmias, ICD-VR was implanted and amiodarone was prescribed. Treatment with propylthiouracil (PTU and dexamethasone was initiated after thyrotoxicosis was diagnosed. Three weeks after the introduction of PTU, hepatotoxicity was registered, thus the medication was discontinued. Thyrozol, which regulates the hepatotoxicity parameters, was introduced. Sodium perchlorate and glucocorticoid (per os, IV and intrathyroidal therapy was introduced. The treatment had lasted for fifty days and laboratory signs of thyrotoxicosis were still present, which is why a total of eight plasmapheresis sessions were performed. Each plasmapheresis resulted in a significant decrease in FT4 and a slight decrease in FT3. After seventy two days of treatment, an optimal hormonal status of the thyroid gland was established and total thyroidectomy was performed. Conclusion: Patient was treated for amiodarone-induced thyrotoxicosis (AIT type 2, which was resistant to conventional therapy for a long period of time. Successful treatment was achieved by applying plasmapheresis although the effect of perchlorate and glucocorticoids application cannot be disregarded.

    A positive crossmatch indicates the presence of donor-specific alloantibodies and is associated with a graft loss rate of >80%; anti-ABO blood group antibodies develop in response to exposure to foreign blood groups, resulting in immediate graft loss. However, a desensitization protocol for highly HLA-sensitized and ABO-incompatible high-titer kidney transplantation has not yet been established. We treated 6 patients with high (≥1:512) anti-A/B antibody titers and 2 highly HLA-sensitized patients. Our immunosuppression protocol was initiated 1 month before surgery and included mycophenolate mofetil (1 g/d) and/or low-dose steroid (methylprednisolone 8 mg/d). Two doses of the anti-CD20 antibody rituximab (150 mg/m(2)) were administered 2 weeks before and on the day of transplantation. We performed antibody removal with 6-12 sessions of plasmapheresis (plasma exchange or double-filtration plasmapheresis) before transplantation. Splenectomy was also performed on the day of transplantation. Postoperative immunosuppression followed the same regimen as ABO-compatible cases, in which calcineurin inhibitors were initiated 3 days before transplantation, combined with 2 doses of basiliximab. Of the 8 patients, 7 subsequently underwent successful living-donor kidney transplantation. Follow-up of our recipients showed that the patient and graft survival rates were 100%. Acute cellular rejection and antibody-mediated rejection episodes occurred in 1 of the 7 recipients. These findings suggest that our immunosuppression regimen consisting of rituximab infusions, splenectomy, plasmapheresis, and pharmacologic immunosuppression may prove to be effective as a desensitization protocol for highly HLA-sensitized and ABO-incompatible high-titer kidney transplantation.

    The use of bortezomib as a treatment modality of AHR improved and stabilized graft function (clinical response) in the majority of patients. Its use in single dose, even combined with rituximab, does not seem to be useful to obtain a sustained clinical response neither to reduce HLAabs level. The use of 4 doses of bortezomib in days 1, 4, 7, and 10 (1.3 mg/m2 BSA each) plus plasmapheresis produced both a good clinical response and a reduction in DSA. Moving forward, it will necessary to define the long-term effectiveness of bortezomib and whether rituximab administration is indispensable to achieve this goal.

    2003-01-01

    Full Text Available Serum immunoglobulins (IgG, IgA and IgM and immune complexes IgG (IcG were measured in 58 cases of acute inflammatory demyelinating neuropathy, popularly known as Guillian Barre′ syndrome, and in 30 healthy controls using single radial immunodiffusion assay. Immunoglobulin and immune complex levels were significantly elevated in patients as compared to controls. The increased levels of immunoglobulins and immune complexes may contribute to the pathogenesis of the disease and provide rationale for therapeutic plasmapheresis.

    Rheumatoid arthritis (RA) is one of the commonest rheumatological diseases. Renal involvement is not common but can occur as a result of chronic inflammation as part of disease process or drug toxicity. Thrombotic microangiopathy (TMA) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ failure of variable severity. Only a few cases of TMA in patients with RA were reported to date. We describe a 45-year-old female patient with RA who presented with oliguria and edema. Renal biopsy showed TMA with patchy cortical necrosis. She improved with hemodialysis and plasmapheresis.

    Human error has been identified as a major source of ABO-incompatible blood transfusion which most often results from blood being given to the wrong patient. We present a case of inadvertent administration of ABO-incompatible blood to a 6-mo-old child who underwent congenital heart surgery and discuss the use of invasive therapeutic approaches. Invasive techniques included total circulatory arrest and large-volume exchange transfusion, along with conventional ultrafiltration and plasmapheresis, which could all be performed rapidly and effectively. The combination of standard pharmacologic therapies and alternative invasive techniques after a massive ABO-incompatible blood transfusion led to a favorable outcome in our patient.

    2016-01-01

    Full Text Available We report three cases of effective management of infertility in women with a history of repeated unsuccessful IVF attempts, who have developed antibodies to hCG. A novel approach to conservative treatment of immunologic reproductive failure, suggested for selected patients, included membrane plasmapheresis, combined prednisolone, and intravenous immunoglobulin therapy. No adverse side effects were observed; all cases resulted in pregnancy and subsequent life births. In order to be given an adequate efficient treatment, women with recurrent implantation failure should be suspected for autoimmune factor of infertility and its possible association with anti-hCG autoimmunity.

    Full Text Available Purpose: We report a case of unilateral exudative retinal detachment in a patient with thrombotic thrombocytopenic purpura (TTP, without associated hypertension, successfully treated with plasmapheresis. Case Report: A 46-year-old woman with a medical history of TTP presented with unilateral exudative retinal detachment. Biological and radiological assessment eliminated other causes of exudative retinal detachment, including hypertension. Plasma exchange was performed, followed by a rapid improvement in visual acuity and total disappearance of serous detachment. Conclusion: Exudative unilateral retinal detachment is a rare complication of TTP and can be successfully treated by plasma exchange.

    2016-03-01

    Full Text Available Renal disease secondary to vasculitis associated with anti-neutrophil cytoplasmic antibodies (ANCA can lead to chronic renal disease requiring renal replacement therapy. In these patients, kidney transplantation offers excellent long-term rates of allograft and patient survival; consequently, they can be trasplanted when the clinical disease activity has remitted. However, the risk of disease relapses in the renal allograft remains, although at lower rates due to modern immunosuppressive regimes. We describe the case of a male patient with extracapillary glomerulonephritis type III C-ANCA (+ who developed a recurrence in the renal allograft 8 years after transplantation. Intensive immunosupression with plasmapheresis controlled the disease.

    Fifteen patients with multiple myeloma stage III were treated with a combination of cytostatics and plasmapheresis in a sequential trial running for 60 weeks. Thirteen patients showed clinical improvement and ten a reduction of thieir myeloma protein by at least 50%. Bone X-ray examination was performed every 15 weeks. Progression of bone lesions was seen in one patient, whereas the radiographic picture was unchanged in the others. It is concluded that bone X-ray, although essential in the diagnosis and staging of multiple myeloma, is not suitable for the monitoring of patients during treatment.

    2015-02-01

    De novo thrombotic microangiopathy (TMA) following renal transplantation is a severe complication associated with high rates of allograft failure. Several immunosuppressive agents are associated with TMA. Conventional approaches to managing this entity, such as withdrawal of the offending agent and/or plasmapheresis, often offer limited help, with high rates of treatment failure and graft loss. We herein report a case of drug induced de novo TMA successfully treated using the C5a inhibitor eculizumab in a renal transplant patient. This report highlights a potentially important role for eculizumab in settings where drug-induced de novo TMA is refractory to conventional therapies.

    Full Text Available Guillain-Barré syndrome (GBS is an acute symmetrical pa- ralyzing disease due to a demyelinating polyrradiculoneuropathy, often induced by a preceding infection 1. The main modalities for the treatment of GBS include plasmapheresis and intrave- nous immune globulin. Reports of the use of IVIG in children with GBS are limited: 1 g/kg for two days or 400 mg/kg for five days. While these studies in children are not definitive because of design limitations, their results are consistent with the larger randomized trials in adults 2,3.

    Thrombotic thrombocytopenic purpura (TTP) is a disseminated form of thrombotic microangiopathy with clinical findings consisting of fever, microangiopathic hemolytic anemia (MAHA), thrombocytopenia, fluctuating neurologic impairment and renal dysfunction. However, Microangiopathic hemolytic anemia has been described in association with disseminated malignancies, most commonly adenocarcinoma of the breast or stomach. We present three patients with microangiopathic anemia in whom metastatic cancer was finally diagnosed; however, they died of refractory hemolytic anemia in the end. The occurrence of microangiopathic hemolytic anemia and thrombocytopenia in patients with disseminated malignant in gastric adenocarsinoma is well documented. Therefore, the diagnosis of tumor-associated TTP should be considered in unresponsive TTP patient treated with plasmapheresis. (author)

    2017-06-01

    Full Text Available A female 27 presented with nausea and diplopia for 1 week. On examination she had normal vertical gaze but would develop convergence with miosis whenever she made horizontal saccades. Pupils were 6 mm and unreactive to light. MRI showed extensive hyperintensity in the dorsal midbrain and thalamus. Spinal MRI and CSF were both normal. Serum aquaporin-4-antibody was positive. She was treated with steroids and plasmapheresis and after 3 months convergence spasm resolved but pupils remained unreactive. Neuromyelitis optica often presents with brainstem signs, rarely a dorsal midbrain syndrome. Convergence spasm is occasionally of organic neurologic origin.

    2016-07-01

    Cast nephropathy is the most common manifestation of renal injury in patients with multiple myeloma but is rarely reported in other conditions. We are reporting our experience in caring for a teenager with a metastatic neuroendocrine carcinoma who developed rapidly progressive kidney injury that advanced to end-stage renal disease. On renal biopsy extensive tubular necrosis and intratubular eosinophilic casts were noted. This previously unreported finding should prompt oncologists to closely monitor for such a complication in patients with secretory tumors. Whether early plasmapheresis could be of benefit, as has been tried in multiple myeloma, remains to be determined.

    Full Text Available Diagnostic criteria and treatment protocols for acute antibody-mediated rejection (AMR of kidney allograft remain controversial. We report the case of early severe AMR after primary kidney transplantation. The graft removal was considered in the absence of treatment efficacy and in the presence of systemic infl ammatory response syndrome. However, at surgery the graft looked normal and it was not removed. The repeated treatment course (plasmapheresis, antithymocyte globulin, intravenous immunoglobulin and rituximab was effective. The patient has good and stable graft function in 1 year after transplantation.

    Adsorption of viral particles from the blood plasma of patients with viral hepatitis B and C on modified nanodiamonds (MNDs) was shown in the in vitro experiments. PCR method showed the treatment of plasma with MNDs leads to a decrease in the viral load by 2-3 orders of magnitude or more in both cases studied. These results make it possible to predict the applicability of MNDs for the development of new technologies of hemodialysis and plasmapheresis for binding and removal of viral particles from the blood of infected patients.

    Full Text Available Renato Mantegazza, Silvia Bonanno, Giorgia Camera, Carlo AntozziDepartment of Neuromuscular Diseases and Neuroimmunology, Fondazione Istituto Neurologico Carlo Besta, Milan, ItalyAbstract: Myasthenia gravis (MG is an autoimmmune disease in which autoantibodies to different antigens of the neuromuscular junction cause the typical weakness and fatigability. Treatment includes anticholinesterase drugs, immunosuppression, immunomodulation, and thymectomy. The autoimmune response is maintained under control by corticosteroids frequently associated with immunosuppressive drugs, with improvement in the majority of patients. In case of acute exacerbations with bulbar symptoms or repeated relapses, modulation of autoantibody activity by plasmapheresis or intravenous immunoglobulins provides rapid improvement. Recently, techniques removing only circulating immunoglobulins have been developed for the chronic management of treatment-resistant patients. The rationale for thymectomy relies on the central role of the thymus. Despite the lack of controlled studies, thymectomy is recommended as an option to improve the clinical outcome or promote complete remission. New videothoracoscopic techniques have been developed to offer the maximal surgical approach with the minimal invasiveness and hence patient tolerability. The use of biological drugs such as anti-CD20 antibodies is still limited but promising. Studies performed in the animal model of MG demonstrated that several more selective or antigen-specific approaches, ranging from mucosal tolerization to inhibition of complement activity or cellular therapy, might be feasible. Investigation of the transfer of these therapeutic approaches to the human disease will be the challenge for the future.Keywords: myasthenia gravis, therapy, immunosuppression, thymectomy, plasmapheresis

    Obtaining of a therapeutic dose of platelets from donors, necessary to stop spontaneous hemorrhage and sufficient enough to correct hemostasis in surgical interventions in patients with amegakaryocytic thrombocytopenia, therapeutic plasmapheresis with the removal of 1.5-2.01 of plasma, effective erythrocytapheresis can be done with the help of refrigerator centrifuges and plastic containers. This method can be also employed for effective leukocytapheresis in patients with the leukocyte level exceeding 100.10(9)/l. It is simple, economical, reliable; several donors (patients) can be involved in the procedure at a time. Blood cell separators can be most effectively used for therapeutic lymphocytoplasmapheresis, massive plasmapheresis with the removal of over 2.51 of plasma, for obtaining a large number of platelets and granulocytes. The CS-3000 blood cell separator ensures automatic control over blood separation and possible complications during a procedure; a constant temperature regimen of blood separation; one-time use of equipment in direct contact with patient's (donor's) blood; a high efficacy and safety of the procedure.

    2016-04-01

    Full Text Available Pulmonary renal syndrome is a class of small vessel vasculitides that are characterized by the dual presentation of diffuse alveolar hemorrhage (DAH and glomerulonephritis. Pulmonary renal syndrome has multiple etiologies, but its development has been rarely reported following infection with group A streptococcus. We present the case of a 36-year-old Native American male who was transferred to our facility due to refractory hypoxic respiratory failure. He had been diagnosed with streptococcal pharyngitis 2 weeks prior to admission. Given the presence of hemoptysis, bronchoscopy was performed and was consistent with DAH. Urinalysis demonstrated hematuria and proteinuria, in the setting of elevated creatinine and blood urea nitrogen. Additionally, antistreptolysin O titer was positive. Given the constellation of laboratory findings and history of streptococcal pharyngitis, the patient was diagnosed with PRS secondary to streptococcal infection. High-dose methylprednisolone was initiated with concomitant plasmapheresis. He was extubated successfully after his respiratory status improved and was eventually discharged home after making a full recovery within 2 weeks after admission. This case illustrates the importance of clinically relevant sequelae of streptococcal infection as well as the appropriate treatment of PRS secondary to streptococcal pharyngitis with plasmapheresis and intravenous corticosteroids.

    Full Text Available Objective: To evaluate the efficiency of extracorporeal hemocorrection used in the complex therapy in patients with a pyoinflammatory process in the lung.Materials and methods: 62 patients, including 22 patients with lung abscess who underwent routine plasmapheresis and 40 patients with varying pyoinflammatory lung diseases who received modified hemocorrection — plasma exchange combined with laser extracorporeally washed-off cytomass irradiation, were examined and treated. The severity of their general condition was assessed by the SAPS scale and the severity of intoxication was evaluated by the content of low and medium-molecular weight substances (LMMWSs. The hemostatic system was studied by standardized studies.Results. Routine plasmapheresis was established to produce no impact on platelet functional activity within the first 24 hours and, three days later, promoted the progression of disseminated intravascular coagulation. A combination of plasma exchange and laser extracorporeally washed-off cytomass irradiation in patients with pyoinflam-matory lung diseases was attended by a lower blood coagulative activity and plasmin stabilization with attenuated throm-binemia. The plasma and erythrocytic levels of LMMWSs decreased and their urinary concentrations increased, which is indicative of the body’s detoxification block disorders irrespective of the severity of the disease.Conclusion. It is expedient to apply the plasma-exchanging technique in combination with laser extracorporeally washed-off cytomass irradiation to patients with the uncomplicated and complicated course of pulmonary pyoinflammatory processes without the signs of multiple organ dysfunction on admission to a specialized hospital.

    Carr, Rosalie A; Rejowski, Benjamin J; Cote, Gregory A; Pitt, Henry A; Zyromski, Nicholas J

    2016-01-01

    We sought to define the severity and natural history of hypertriglyceridemia induced acute pancreatitis (HTG-AP), specifically whether HTG-AP causes more severe AP than that caused by other etiologies. Systematic review of the English literature. Thirty-four studies (15 countries; 1972-2015) included 1340 HTG-AP patients (weighted mean prevalence of 9%). The median admission triglyceride concentration was 2622 mg/dl (range 1160-9769). Patients with HTG have a 14% weighted mean prevalence of AP. Plasmapheresis decreased circulating triglycerides, but did not conclusively affect AP mortality. Only 7 reports (n = 392 patients) compared severity of HTG-AP to that of AP from other etiologies. Of these, 2 studies found no difference in severity, while 5 suggested that HTG-AP patients may have increased severity compared to AP of other etiology. 1) hypertriglyceridemia is a relatively uncommon (9%) cause of acute pancreatitis; however, patients with hypertriglyceridemia have a high (14%) incidence of acute pancreatitis; 2) plasmapheresis may offer specific therapy unique to this patient population; and 3) data specifically comparing the severity of HTG-AP with AP caused by other etiologies are heterogeneous and scarce.

    2012-07-01

    Full Text Available Late-onset erythropoietic protoporphyria (EPP is rare, and it is usually associated with an acquired somatic mutation of the ferrochelatase gene secondary to hematological malignancy such as myelodysplastic syndrome or myeloproliferative disorder. In 0.5–1% of patients with EPP, deposition of protoporphyrin in the liver leads to progressive liver insufficiency. Herein, we report the case of a 67-year-old female who developed EPP with typical photosensitivity and hemolytic anemia. Six months later, she was admitted with acute liver damage with a rapidly progressing course, and developed liver insufficiency. She recovered from the liver insufficiency after undergoing plasmapheresis and red blood cell exchange transfusion. A bone marrow examination revealed normal features; however, a cytogenetic analysis identified an abnormal clone of cells with a translocation between chromosomes 13q12 and 18q21.1. This is the first report of a patient who recovered from liver insufficiency. The results of this report suggest that plasmapheresis and red blood cell exchange transfusion are effective for treating liver insufficiency in patients with late-onset EPP.

    Full Text Available  AbstractBackground: Thrombotic microangiopathy (TMA is a rare syndrome that leads to excessive formation of blood clots, microthrombosis and is accompanied by non-autoimune haemolytic anemia and thrombocytopenia. Only few cases describing TMA caused by cancer are being reported in the literature.Patient: A 42-year old male patient with metastatic carcinoma of sigma and several accompanying diagnoses (pulmonary embolism, deep vein thrombosis, cerebrovascular insult had later developed clinical and laboratory signs of TMA. TMA was unresponsive to plasmapheresis, which was discontinued and first cycle of chemotherapy was applied. The patient died soon after. The autopsy did not provide any additional information about the disease, there were no signs of malignant bone marrow infiltration.Conclusion: The diagnosis of secondary TMA remains a diagnostic and therapeutic challenge. It appears as a rare complication in patients with cancer. Treatment is difficult because the cause of TMA (malignancy is hard to remove. Patients with cancer do not respond to plasmapheresis, which often delays the application of chemotherapy, the only effective treatment for TMA. Consequently this condition has poor prognosis.

    The authors evaluated the feasibility of systemic vascular perfusion with saline (mimicking plasmapheresis) as a method to enhance tumor-specific monoclonal antibody (MoAb) tumor/background ratios. Perfusion in rats dropped whole-body 5G6.4 levels significantly at both perfusion times. The drop in whole-body radioactivity with perfusion was significantly greater for the animals perfused at 4 h post i.v. 5G6.4 antibody injection (48.3 +- 5.1%) than for those perfused at 24h post i.v. antibody injection (32.9 +- 2.9%). In the nude mice with ovarian cancer xenografts, gamma camera images of tumors were visually and quantitatively by computer image analysis enhanced by perfusion, with a 2.33-fold greater decline in whole body uptake than in the tumor. These studies show that much background antibody radioactivity can be removed using whole-body perfusion with saline, that the decline in whole body activity is larger with 4 than 24h perfusion and that tumor imaging can be enhanced by this approach. This and similar approaches that increase relative tumor antibody uptake such as plasmapheresis may be useful in imaging and therapy with radiolabeled antibodies.

    Full Text Available Objective. To comparatively analyze the efficiency of methods for extracorporeal detoxification (ED of the body in abdominal sepsis (AS and to choose the optimum detoxifying methods in relation to the level of endotoxicosis.Material and methods. 56 patients (41 males and 15 females; mean age 39.4±12.2 years with surgical abdominal infection of various genesis, complicated by the development of sepsis whose treatment included ED methods, were examined. The level of intoxication and the efficiency of detoxification were evaluated by general clinical and biochemical blood parameters, the leukocytic intoxication index, the levels of low and medium molecular-weight substances in the body’s media. Hemosorption, plasmapheresis, hemodialysis, hemodiafiltration, and hemofiltration were used for detoxification.Results. Surgical abdominal infection is accompanied by endotoxemia that has no clear nosological specificity, but it depends on the pattern of a clinical course of the disease and is most pronounced in the septic syndrome. In AS, 80.4% of the patients are observed to have an irreversible decompensation phase and a terminal degree of endotoxicosis, which require detoxification. The use of different ED methods according to the level of intoxication may reduce the level of endotoxicosis and yield a persistent beneficial effect in 85.2% of cases of its application. Conclusion. Filtration and dialysis techniques (hemodialysis, hemofiltration, and hemodiafiltration are the methods of choice in AS. Hemosorption and plasmapheresis may be recommended for use at the early stages of endotoxicosis development and in preserved renal excretory function.

    Full Text Available A plasma component is responsible for altered glomerular permeability in patients with focal segmental glomerulosclerosis. Evidence includes recurrence after renal transplantation, remission after plasmapheresis, proteinuria in infants of affected mothers, transfer of proteinuria to experimental animals, and impaired glomerular permeability after exposure to patient plasma. Therapy may include decreasing synthesis of the injurious agent, removing or blocking its interaction with cells, or blocking signaling or enhancing cell defenses to restore the permeability barrier and prevent progression. Agents that may prevent the synthesis of the permeability factor include cytotoxic agents or aggressive chemotherapy. Extracorporeal therapies include plasmapheresis, immunoadsorption with protein A or anti-immunoglobulin, or lipopheresis. Oral or intravenous galactose also decreases Palb activity. Studies of glomeruli have shown that several strategies prevent the action of FSGS sera. These include blocking receptor-ligand interactions, modulating cell reactions using indomethacin or eicosanoids 20-HETE or 8,9-EET, and enhancing cytoskeleton and protein interactions using calcineurin inhibitors, glucocorticoids, or rituximab. We have identified cardiotrophin-like cytokine factor 1 (CLCF-1 as a candidate for the permeability factor. Therapies specific to CLCF-1 include potential use of cytokine receptor-like factor (CRLF-1 and inhibition of Janus kinase 2. Combined therapy using multiple modalities offers therapy to reverse proteinuria and prevent scarring.

    Full Text Available Introduction: Hemolytic-uremic syndrome (HUS is a leading cause of acute renal failure in infants and young children. It is traditionally defined as a triad of acute renal failure, hemolytic anemia and thrombocytopenia that occur within a week after prodromal hemorrhagic enterocolitis. Severe cases can also be presented by acute respiratory distress syndrome (ARDS, toxic megacolon with ileus, pancreatitis, central nervous system (CNS disorders and multiple organ failure (MOF. Case presentation: A previously healthy 4-year old Caucasian girl developed acute renal failure, thrombocytopenia and hemolytic anemia following a short episode of abdominal pain and bloody diarrhea. In the next week of, what initially appeared as typical HUS, she developed MOF, including ileus, pancreatitis, hepatitis, coma and ARDS, accompanied by hemodynamic instability and extreme leukocytosis. Nonetheless, the girl made a complete recovery after one month of the disease. She was successfully treated in the intensive care unit and significant improvement was noticed after plasmapheresis and continuous veno-venous hemodialysis. Conclusions: Early start of plasmapheresis and meticulous supportive treatment in the intensive care unit, including renal placement therapy, may be the therapy of choice in severe cases of HUS presented by MOF. Monitoring of prognostic factors is important for early performance of appropriate diagnostic and therapeutical interventions.

    Full Text Available Abstract Background To report our experience of a rather uncommon drug interaction, resulting in hemolytic uremic syndrome (HUS. Methods Two consecutive cases of hemolytic uremic syndrome were diagnosed in our service. In both patients the use of macrolides in patients taking Tacrolimus, resulted in high levels of Tacrolimus. Results The first patient was a 48 years old female with Bilateral emphysema. She underwent Single Sequential Lung Transplantation. She developed reperfusion injury requiring prolonged stay. Tacrolimus introduced (Day 51. The patient remained well up till 5 months later; Erythromycin commenced for chest infection. High Tacrolimus levels and a clinical diagnosis of HUS were made. She was treated with plasmapheresis successfully. The second case was a 57 years old female with Emphysema & A1 Antithrypsin deficiency. She underwent Right Single Lung Transplantation. A2 rejection with mild Obliterative Bronchiolitis diagnosed 1 year later and she switched to Tacrolimus. She was admitted to her local Hospital two and a half years later with right middle lobe consolidation. The patient commenced on amoxicillin and clarithromycin. Worsening renal indices, high Tacrolimus levels, hemolytic anemia & low Platelets were detected. HUS diagnosed & treated with plasmapheresis. Conclusions There are 21 cases of HUS following lung transplantation in the literature that may have been induced by high tacrolimus levels. Macrolides in patients taking Cyclosporin or Tacrolimus lead to high levels. Mechanism of action could be glomeruloconstrictor effect with reduced GFR increased production of Endothelin-1 and increased Platelet aggregation.

  11. The Gift Relationship Revisited.

    If unremunerated blood donors are willing to participate, and if the use of them is economical from the perspective of those collecting blood, I can see no objection to their use. But there seems to me no good reason, moral or practical, why they should be used. The system of paid plasmapheresis as it currently operates in the United States and in Canada would seem perfectly adequate, and while there may always be ways in which the safety and efficiency of supply could be increased, there seems no reason whatever to think that there would be an improvement if the current system changed so as to rely entirely on unpaid donors. Further, given the adequacy of paid plasmapheresis, I could see no problem if the collection of whole blood were to take place on a similar, fully-commercial, basis. Such a view is controversial. To argue for it, this paper offers just one strand in a complex argument: a critique of Richard Titmuss's Gift Relationship, which holds an iconic position in the critical literature on the paid provision of blood. As I conclude: all told, there seems no good basis for rejecting supply of whole blood for money--let alone the supply of blood plasma.

    Full Text Available Tetanus antitoxin is quantified in Cuba at blood banks, from the serum of immunized donors, to produce aspecific human gamma globulin. A heterogeneous indirect immunoenzymatic assay is used, using the serum as analytical sample. The possible use of plasma obtained from plasmapheresis as alternative sample was evaluated in this research, to minimize the volume of total blood extracted to the donors. One hundred plasma donors who came to donate between October and November 2013 were selected by simple random sampling. Serum sample was obtained for extraction of 5 mL of blood, deposited in dry glass tube. While the other sample took 1.5 mL of plasma in a plastic tube with cover, at the end of the donation directly of the unit of plasma collected. Comparison of the difference between the means of both groups was done using SPSS for Windows. It was found that the values obtained in serum were bigger than those obtained in plasma. Difference between the means of both groups was statistically significant (p 0.00. It is not advisable to use the obtained plasma of the plasmapheresis as analytic sample in this assay.

    Graft failure due to chronic rejection is greater among renal transplant patients with donor-specific antibody (DSA) than among DSA-free patients. For patients dependent on deceased donor transplantation, preoperative desensitization to eliminate DSAs may be impractical. We speculated that perioperative desensitization might eliminate preexisting DSAs and prevent de novo DSAs and improve graft outcomes. We report that brief perioperative desensitization using either intravenous immunoglobulin (IVIG) or plasmapheresis/IVIG (PP/IVIG) treatment improves clinical outcomes among patients with positive crossmatches. Immediately following deceased donor transplantation, 235 renal recipients were assigned points for PRA and flow crossmatches (FCXM): delayed graft function (DGF) ≤ 1 point received standard therapy; 2 points received high-dose IVIG; and ≥3 points received PP/IVIG. The DSAs were serially monitored by single antigen bead luminex for 1 year. Five-year clinical outcomes were determined from the chart review. All desensitized patients had preoperatively positive FCXM with DSA. Rejection was more common (P desensitized than nonsensitized groups. However, overall graft survivals were similar between the groups (P = not significant) and superior to historic untreated patients (P 90% in all desensitizated patients with DSA elimination as well as PP/IVIG patients with residual DSA. In contrast, IVIG patients with persistent DSA had poorer graft survival (45%, P desensitization improved overall graft survival of sensitized patients compared to historic untreated patients. Plasmapheresis/IVIG had greater impact on DSA eradication and graft survival than IVIG alone. © 2016, NATCO.

    Full Text Available Ninad Parekh, Edward Epstein, Suzanne El-Sayegh Department of Medicine, Division of Nephrology, Staten Island University Hospital, Staten Island, NY, USA Introduction: Diagnosing the etiology of a rapidly progressive glomerulonephritis is of vital importance to guide appropriate therapeutic management. This case highlights the complexity involved in establishing diagnosis when presentation is atypical. In certain cases diagnosis cannot be established based on clinical presentation or biopsy findings alone, and critical analysis of biopsy findings in context of clinical presentation is crucial to guide the clinical decision-making process.Case presentation: A 47-year-old Hispanic male with history of granulomatosis with polyangiitis (GPA in remission on azathioprine, presented with fatigue and lethargy. Physical examination was unremarkable. Laboratory data revealed elevated creatinine and otherwise normal electrolytes. Urinalysis showed numerous dysmorphic red blood cells with few red cell casts. His serologic results were all negative except anti-proteinase-3 antibody at very low titers. Kidney biopsy showed necrotizing crescentic glomerulonephritis with linear immunoglobulin G staining along the basement membrane.Conclusion: This case presented conflicting serologic and histopathologic findings. The presence of anti-proteinase-3 antibody supported diagnosis of recurrence of GPA. However, linear staining of immunoglobulin G (IgG on immunofluorescence (IF staining of renal biopsy supported anti-glomerular basement membrane (GBM disease. The treatment of anti-GBM disease and GPA both involve immunosuppression with prednisone and cyclophosphamide. However, patients with anti-GBM disease are also treated with plasmapheresis early in the disease presentation to prevent further damage. The patient with GPA, on the other hand, was shown to benefit from plasmapheresis only in the case of severe renal disease (serum creatinine level more than 5 mg/dL or

    2013-01-01

    Full Text Available A young lady was ventilated on intensive care for a prolonged period with NMDA receptor encephalitis. She had undergone steroid, immunoglobulin, and plasmapheresis with no evidence of recovery. Her main management issue was the control of severe orofacial and limb dyskinesia. Large doses of sedating agents had been used to control the dystonia but were ineffective, unless she was fully anaesthetised. The introduction of a ketamine infusion was associated with a dramatic improvement in her symptoms such that it was possible to remove her tracheostomy two days after commencement. She was discharged shortly after that and is making a good recovery. The successful use of ketamine has not previously been described in this context, and we hope this case report will provide some insight into the management of this rare but serious condition.

    2015-07-01

    Full Text Available Angioedema secondary to C1 inhibitor deficiency has been rarely reported to be associated with systemic lupus erythematosus. A genetic defect of C1 inhibitor produces hereditary angioedema, which is usually presented with cutaneous painless edema, but edema of the genital area, gastrointestinal and laryngeal tracts have also been reported. In lupus patients, angioedema may be the result of an acquired type of C1 inhibitor deficiency, most probably due to antibody formation directed against the C1 inhibitor molecule. Herein we report a new case of lupus nephritis that developed angioedema and a rapid course of disease progression with acute renal failure and alveolar hemorrhage without response to high dose steroid and plasmapheresis.

  17. Strategies for building reference standards for autoantibodies

    Full Text Available Producing robust, certified, traceable reference material for autoantibody testing is a vital element in maintaining the validity of results that are generated in the daily clinical laboratory routine. This is a huge challenge because of the high number of variables involved in the detection and measurement of the autoantibodies. The production of such materials is time consuming and needs rigorous attention to detail; this is best achieved by an overarching independent body who will oversee the process in a not for profit manner.Much effort has been made to build international standards for quantitative and qualitative assays based on monoclonal antibodies, obtained from affinity purification and plasmapheresis. The big challenge is to respect individual differences in immune response to the same antigen. A promising ongoing initiative is the construction of pools with monospecific samples from different individuals.

    The use of bortezomib as a treatment modality of AHR improved and stabilized graft function (clinical response) in the majority of patients. Its use in single dose, even combined with rituximab, does not seem to be useful to obtain a sustained clinical response, or to reduce HLAabs level. The use of 4 doses of bortezomib in days 1, 4, 7, and 10 (1.3 mg/m2 BSA each) plus plasmapheresis produced both a good clinical response and a reduction in DSA. Moving forward, it will be necessary to define the long-term effectiveness of bortezomib and whether rituximab administration is indispensable to achieve this goal. Until now, it is evident that many patients needed retreatment and they were well tolerated.

    Full Text Available Severe hypertriglyceridemia (SH represents a therapeutic emergency because of the possibility of developing cardiovascular events and hyperlipemic acute pancreatitis (PA. Most patients with SH suffer primary or genetic abnormality in lipid metabolism in combination with a precipitating factor such as uncontrolled diabetes mellitus, alcoholism, and drug intake. The standard treatment of hypertriglyceridemia (HTG with omega 3 fatty acids and fibrates, along with dietary changes, has no effect on an emergency situation. There are no clinical guidelines to SH, but therapy with insulin, heparin, a combination of both, plasmapheresis, or octreotide have been tested succesfully. We report the case of a 10-year-old girl with clinical acute pancreatitis and diabetic ketoacidosis debut, along with incidental finding of an SH, who had a good outcome after treatment with insulin intravenous infusion.

    Many patients with myasthenia gravis (MG) still find it difficult to maintain daily activities due to chronic residual fatigability and long-term side effects of oral corticosteroids, since full remission is not common. Our analysis demonstrated that disease severity, oral corticosteroids, and depressive state are the major factors negatively associated with QOL, and that QOL of MM status patients taking CSR and is a target of treatment. In order to achieve early MM or better status with prednisolne strategy that can achieve early improvement by performing an aggressive therapy using combined treatment with plasmapheresis and high-dose intravenous methylprednisolone and then maintain an improved status using low-dose oral corticosteroids and calcineurin inhibitors.

    2015-01-01

    Severe gestational hypertriglyceridemia is a potentially life threatening and complex condition to manage, requiring attention to a delicate balance between maternal and fetal needs. During pregnancy, significant alterations to lipid homeostasis occur to ensure transfer of nutrients to the fetus. In women with an underlying genetic predisposition or a secondary exacerbating factor, severe gestational hypertriglyceridemia can arise, leading to devastating complications, including acute pancreatitis. Multidisciplinary care, implementation of a low-fat diet with nutritional support, and institution of a hierarchical therapeutic approach are all crucial to reduce maternal and fetal morbidity. To avoid maternal pancreatitis, close surveillance of triglycerides throughout pregnancy with elective hospitalization for refractory cases is recommended. Careful dietary planning is required to prevent neural and retinal complications from fetal essential fatty acid deficiency. Questions remain about the safety of fibrates and plasmapheresis in pregnancy as well as the optimal timing for induction and delivery of these women. PMID:27512474

    The ways of reducing endotoxemia observed for male dogs at the total X-ray radiation dose equal to 2.9 Gy with detoxicating blood substitutes and plasmapheresis have been studied. The effectiveness of detoxication measures is demonstrated in obvious reduction of intensity as far as pathological processes are concerned in the first 3 days of development of acute radiation sickness. The detoxicating measures at the imitial period of acute radiation sickness are expedient when perishing of the pool of polypotent cells of hemopoietic system is not a factor affecting survival and when the ultimate termination of acute radiation sickness bears no relation to lethal lesion of hemopoiesis. 7 refs.; 6 figs.; 1 tab

    In the last few years, there has been an explosion of new drugs acting on the clinical course of multiple sclerosis (MS) but less attention has been paid to better knowledge of the symptoms of this disease and their pathogenesis and treatment, which is essential to improve patients' quality of life. Because many patients have numerous concurrent symptoms during their clinical course, their management is complex and consequently it is important to know which symptoms are a direct result of the degenerative lesions of MS. The present article describes all the therapeutic options available for spasticity and its associated pain, paroxystic symptoms, fatigue, genitourinary disorders and sexual dysfunction, tremor, ataxia, gait disorder and cognitive impairment, with special emphasis on novel treatments. The article also defines exacerbations, how to recognize them and the available treatments, mainly oral administration of high-dose methylprednisolone and plasmapheresis.

    A case of severe Guillain-Barré syndrome (GBS) was treated with high dose intravenous immunoglobulin (IVIG), 400 mg.kg-1.days-1, over three consecutive days. The treatment was repeated once. We observed a time-related response between immunoglobulins administration and clinical improvement. The pathologic lesions of the GBS suggest that this syndrome has an immunologic basis: a humoral factor is probably not the only immunological mechanism and cellular mechanisms are also likely to be of importance. Specific mechanisms might also be present in GBS, such as anti-idiotypic suppression of autoantibodies, and elimination of circulating immune complexes. Treatment with IVIG might have several therapeutic advantages over plasmapheresis: IVIG is easily infused without any delay, is easily available and has been used widely without serious complications.

    We describe a 24-year-old woman with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis that developed 3 weeks after normal delivery. She was treated with methylprednisolone, intravenous immunoglobulin, and plasmapheresis, in addition to teratoma excision. However, her recovery was slow, and dysmnesia and mental juvenility persisted even two years after onset. To date, five patients with postpartum anti-NMDAR encephalitis have been reported. All of those patients showed psychotic symptoms and were suspected of having postpartum psychosis in the early period of the encephalitis. Changes in hormonal factors, modification of immune tolerance, or retrograde infection of the ovary may be contributing factors for postpartum anti-NMDAR encephalitis.

    Full Text Available ABSTRACT The epidemics of Chikungunya virus (CHIKV and Zika virus (ZIKV infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others. The diagnosis is based on clinical, epidemiological, and laboratory criteria. The most common symptoms of ZIKV infection are skin rash (mostly maculopapular, fever, arthralgia, myalgia, headache, and conjunctivitis. Some epidemics that have recently occurred in French Polynesia and Brazil, reported the most severe conditions, with involvement of the nervous system (Guillain-Barré syndrome, transverse myelitis, microcephaly and meningitis. The treatment for ZIKV and CHIKV infections are symptomatic and the management for neurological complications depends on the type of affliction. Intravenous immunoglobulin, plasmapheresis, and corticosteroid pulse therapy are options.

    Full Text Available Warm autoimmune hemolytic anemia (wAIHA is the most common form of AIHA, with corticosteroids in first-line treatment resulting in a 60–80% response rate. Atypical wAIHA and IgG plus complement mediated disease have a higher treatment failure rate and higher recurrence rate. We report a case of severe wAIHA secondary to Waldenström macroglobulinemia with life threatening intravascular hemolysis refractory to prednisone, rituximab, splenectomy, and plasmapheresis. A four-week treatment of eculizumab in this heavily pretreated patient resulted in a sustained increase in hemoglobin and transfusion independence, suggesting a role for complement inhibition in refractory wAIHA.

    2011-01-01

    Neuropsychiatric systemic lupus erythematosus (NPSLE) is the least understood, yet perhaps the most prevalent manifestation of lupus. The pathogenesis of NPSLE is multifactorial and involves various inflammatory cytokines, autoantibodies, and immune complexes resulting in vasculopathic, cytotoxic and autoantibody-mediated neuronal injury. The management of NPSLE is multimodal and has not been subjected to rigorous study. Different treatment regimens include nonsteroidal anti-inflammatory drugs, anticoagulation, and immunosuppressives such as cyclophosphamide, azathioprine, mycophenolate mofetil, and methotrexate. For refractory NPSLE, intravenous immunoglobulin (IVIG), plasmapheresis, and rituximab have been used. Adjunctive symptomatic treatment complements these therapies by targeting mood disorders, psychosis, cognitive impairment, seizures or headaches. Several new biological agents are being tested including Belimumab, a human monoclonal antibody that targets B lymphocyte stimulator. This review focuses on the pathophysiology, treatment, and new potential therapies for neuropsychiatric manifestations of systemic lupus erythematosus. PMID:22379459

The patient presented to an outside hospital and was treated for presumptive mixed cryoglobulinemia with corticosteroid therapy. When the patient did not improve, he was transferred to a tertiary care center for possible Rituximab and/or plasmapheresis. Further investigation revealed Enterococcus bacteremia with subsequent workup consistent with infective endocarditis (IE. This case highlights a diagnostic dilemma and demonstrates the importance of a thorough evaluation as it pertains to overlapping features of IE and mixed cryoglobulinemia.

    Full Text Available Goodpasture syndrome is a rare autoimmune disease, with significant morbidity and mortality in young people and otherwise healthy population. Complete disease remission is possible with prompt diagnosis and treatment. We report 3 cases with Goodpasture syndrome treated at the Department of Nephrology, University Clinic of Nephrology, with different outcome. All of the patients were with similar clinical feature, with renal failure that needed treatment with hemodialysis. But results of the treatment with plasmapheresis indicate that this procedure reduces morbidity in patients with Goodpasture syndrome. The clinical course and the outcome of the disease were different. The disease is unpredictable, and the early diagnosis and start with the treatment is important for the remission.

    Full Text Available Meningococcemia is a highly mortal disease that can cause septic shock and multiple organ failure, which can be accompanied by sudden onset, rapid course, purpura fulminans and diffuse intravenous coagulation tables. Mortality increases when meningococcal causes to meningitis. The fact that it is the cause of neurological sequelae and extremity losses even in the recovering cases makes the support provided by the intensive care unit quite important in the management of cases. A case with meningococcal meningitis with high mortality, who was successfully treated through the use of supportive methods, such as monitorization, mechanical ventilation practices with new modalities, plasmapheresis and sympathetic ganglion blockage, has been presented in company with the literature.

    Full Text Available Although the long-term use of immunosuppressives – supplemented with more aggressive treatments such as immunoadsorption, intravenous immunoglobulins, or plasmapheresis in recalcitrant cases has dramatically improved the prognosis of pemphigus vulgaris, opportunistic infections secondary to immunosuppression continue to cause significant mortality. We report four cases– three old ones, who had accumulated significant morbidities over their disease duration ranging from 5 to 10 years, and the fourth, a teenage female intolerant to corticosteroids and idiosyncratic to methotrexate– who achieved complete remission on administration of rituximab by the lymphoma protocol. One of the old cases who had recalcitrant mucositis experienced its complete subsidence without any adjuvant whatsoever. All continue to remain asymptomatic for 11–20 months. None had infusion reactions or any delayed side effects.

    Full Text Available Context: Chronic inflammatory demyelinating polyradiculopathy (CIDP is an acquired and autoimmune neuropathy, characterized by a chronic, rapidly progressive, symmetric weakness. In children, abnormal gait is as a first symptom of muscle weakness. Evidence Acquisition: The diagnosis of CIDP is on the basis of clinical characteristics, electrodiagnostic that shows the severity of the disease, lumbar puncture and spine magnetic resonance imaging (MRI. Results: The first-line treatments in childhood CIDP are intravenous immunoglobulin (IVIG, corticosteroids, and plasmapheresis. Response to first-line therapies is usually satisfactory; nevertheless, recommendations regarding the choice of second-line therapy can only be prepared on the basis of the existing practice described in some of the case reports. Conclusions: This review demonstrated the clinical presentation, diagnosis, and treatment of childhood CIDP.

    Full Text Available Pediatric chronic inflammatory demyelinating polyneuropathy (CIDP is an uncommon acquired disorder of unknown cause, presumed to have an immunological basis. We report 20 patients seen at Children′s Hospital Los Angeles over a period of 10 years. The outcome of our patients was favorable in a vast majority with good response to various treatments instituted. However, residual neurologic deficit was common. The choice of treatment modality was empirical and selected by the treating neurologist. Intravenous immunoglobulin (IVIG and corticosteroids were most commonly utilized for treatment. Plasmapheresis, mycophenolate mofetil, rituximab, cyclophosphamide, azathioprine, and abatacept were added if the patients were refractory to IVIG or became corticosteroid dependent. The spectrum of disease severity ranged from a single monophasic episode, to multiphasic with infrequent relapses with good response to IVIG, to progressive disease refractory to multiple therapies.

    Full Text Available Diagnosis of progressive multifocal leukoencephalopathy is usually based on the clinical presentation, on the demonstration of the brain lesions at the magnetic resonance imaging examination, and on the detection of the JC virus DNA in the cerebrospinal fluid with high sensitive polymerase chain reaction. The role of magnetic resonance imaging specifically in natalizumab-associated progressive multifocal leukoencephalopathy is strengthening, and it is gaining importance not only as an irreplaceable diagnostic tool but also as a surveillance and risk stratifying tool in treated patients. While other imaging techniques such as computed tomography lack sensitivity and specificity, magnetic resonance performed with morphological and functional sequences offers clinicians the possibility to early identify the stage of the disease and the emergence of an immune reconstitution inflammatory syndrome after natalizumab blood removal plasmapheresis.

    Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome (CSS), is a small vessel vasculitis associated with eosinophilia and asthma. Clinical manifestations commonly seen in patients presenting with EGPA range from upper airway and lung involvement to neurological, cardiac, cutaneous, and renal manifestations. Treatment for severe presentations includes steroids, cyclophosphamide, plasmapheresis, and recently, rituximab. Rituximab is associated with a good response in the treatment of vasculitis, but a variable response for the control of allergic symptoms. Here, we report a 16-year-old female patient with severe EGPA (gastrointestinal and cutaneous vasculitis, rhinitis and asthma) refractory to conventional treatment. She was treated with rituximab, which enabled rapid control of the vasculitis component of the disease, but there was no response to rhinitis and asthma. Additionally, she developed severe bronchospasm during rituximab infusion. Sequential rituximab and omalizumab were initiated, leading to remission of all manifestations of vasculitis, rhinitis, and asthma, in addition to bronchospasm related to rituximab infusion.

    Full Text Available Belatacept is a novel immunosuppressant that blocks a T-cell costimulation pathway and is approved for use in adult kidney transplant recipients. Its safety and efficacy have not been established after lung transplantation. We present a case of a lung transplant recipient treated with belatacept. A 56-year-old man underwent bilateral lung retransplantation for bronchiolitis obliterans syndrome (BOS. In the third year posttransplant, he developed hemolytic uremic syndrome (HUS attributed to tacrolimus. Tacrolimus was changed to sirolimus. One month later, he presented with worsening renal function and HUS attributed to sirolimus. Plasmapheresis and steroid pulse were initiated with clinical improvement, and sirolimus was switched to belatacept. He experienced no episodes of cellular rejection but developed recurrent BOS. Complications during treatment included anemia and recurrent pneumonias. The safety and efficacy of belatacept in lung transplantation remains unclear; further studies are needed.

    Myasthenia gravis (MG) is caused by autoantibodies, the majority of which target the muscle acetylcholine receptor (AChR). Plasmapheresis and IgG-immunoadsorption are useful therapy options, but are highly non-specific. Antigen-specific immunoadsorption would remove only the pathogenic autoantibodies, reducing the possibility of side effects while maximizing the benefit. We have extensively characterized such adsorbents, but in vivo studies are missing. We used rats with experimental autoimmune MG to perform antigen-specific immunoadsorptions over three weeks, regularly monitoring symptoms and autoantibody titers. Immunoadsorption was effective, resulting in a marked autoantibody titer decrease while the immunoadsorbed, but not the mock-treated, animals showed a dramatic symptom improvement. Overall, the procedure was found to be efficient, suggesting the subsequent initiation of clinical trials. Copyright © 2017 Elsevier B.V. All rights reserved.

    Utilization of lead-contaminated opium may lead to severe motor neuron impairment and quadriplegia. Forty years oriented old male, opium addict, was admitted to the ICU, with headache, nausea and abdominal pain, and weakness in his lower and upper extremities without definitive diagnosis. The past medical and occupational history was negative. Laboratory investigation showed; anemia (Hb 7.7 g/dl), slightly elevated liver function tests, elevated total bilirubin, and ESR. Abdominal sonography and brain CT scan were normal. EMG and NCV results and neurologic examination were suggestive for Guillain-Barre. He underwent five sessions of plasmapheresis. Blood lead level was > 200 microg/dl. He received dimercaprol (BAL) and calcium disodium edetate (CaEDTA) for two five days session. Upon discharge from ICU all laboratory tests were normal and blood lead level was reduced, but he was quadriplegic. The delayed treatment of lead poisoning may lead to irreversible motor neuron defect.

During the therapy blood samples were taken before a regular INF infusion to quantify the levels of antibodies to the drug and its concentration. According to the efficiency of the drug, two groups were formed: 1 27 (50% patients with INF inefficacy (an exacerbation occurred 2–4 weeks after infusion; 2 27 patients with drug efficacy. The levels of anti-double stranded DNA antibodies and antinuclear factor were estimated in 27 patients to investigate a relationship between the immunogenicity of INF and the presence of autoantibodies in its secondary inefficacy. A plasmapheresis session was carried out in 5 patients before a regular IFN infusion.Results and discussion. Anti-INF antibodies were found in 28 (52% patients, these being more common  in the patients with drug inefficacy than in the others (67 and 37%, respectively; p < 0.05. In the patients with INF inefficacy, anti-INF antibody levels were significantly higher than in those with preserved drug effect (18.33 and 4.67 U/ml, respectively; р < 0.05. Moreover, the serum concentration of INF was not significantly different in these groups (1.6 and 2.96 μg/ml. There was an inverse correlation  between INF concentrations and anti-INF antibodies (r = -0.7; p < 0.05. The level of autoantibodies  did not correlate with that of anti-INF antibodies. Following

    Although convalescent plasma (CP) transfusion was prioritized among potential Ebola treatments by the World Health Organization, there were concerns on the feasibility of its implementation. We report on the successful organization of donor mobilization and plasma collection as part of the Ebola-Tx clinical trial from November 2014 to July 2015 in Conakry, Guinea. Project implementation registers, tools and reports, mission reports, and minutes of research team meetings were used to reconstruct the sequence of events on how donor mobilization was organized, plasmapheresis was set up, and how effective this approach was in collecting CP. An initial needs assessment of the Guinean National Blood Transfusion Center resulted in targeted training of staff on site, resulting in autonomy and independent production of CP within 3 months. The Conakry Ebola Survivors Association played a direct role in donor mobilization and organization of CP donations. A total of 98 Ebola survivors were screened for plasma donation, of which 84 were found eligible for plasmapheresis. Of these, 26 (30.9%) were excluded. The remaining 58 donors made a total of 90 donations, corresponding to 50.9 L of CP. This sufficed to treat the 99 eligible patients enrolled in the trial. Within a poor resource emergency context, transfusion capacity could be rapidly improved through the strengthening of local capacities and gradual transfer of skills coupled with active involvement of Ebola survivors. However, large-scale plasma collection or multisite studies may require further adaptations of both strategy and logistics.

    Autoimmune diseases have common properties characterized by abnormal blood chemistry with high serum autoimmune antibodies, and inflammatory mediators. Those causative pathological substances (CPS) cannot be excreted by physiological mechanisms. Current treatments for autoimmune diseases involve steroids, cytotoxic drugs, plasmapheresis and monoclonal antibodies. Wet cupping therapy (WCT) of prophetic medicine is called Al-hijamah that treats numerous diseases having different etiology and pathogenesis via a pressure-dependent and size-dependent non-specific filtration then excretion of CPS causing clearance of blood and interstitial fluids. Al-hijamah clears blood passing through the fenestrated skin capillaries. Medical bases of Al-hijamah were reported in the evidence-based Taibah mechanism (Taibah theory). Al-hijamah was reported to be an excellent treatment for rheumatoid arthritis that improved patients’ blood chemistry and induced significant clinical improvement and pharmacological potentiation. Al-hijamah improved the natural immunity and suppressed the pathological immunity through decreasing the serum level of autoantibodies, inflammatory mediators, and serum ferritin (a key player in autoimmunity). Al-hijamah reduced significantly pain severity, number of swollen joints and disease activity with no significant side effects. Main steps of Al-hijamah are skin suction (cupping), scarification (sharatmihjam in Arabic) and second suction (triple S technique) that is better therapeutically than the traditional WCT (double S technique). Whenever an excess noxious substance is to be removed from patients’ blood and interstitial fluids, Al-hijamah is indicated. Shartatmihjam is a curative treatment in prophetic teachings according to the prophetic hadeeth: “Cure is in three: in shartatmihjam, oral honey and cauterization. I do not recommend my nation to cauterize”. Al-hijamah may have better therapeutic benefits than plasmapheresis. Al-hijamah may be

    Full Text Available Objective To formulate the best treatment plan for multiple sclerosis (MS patients by evaluating the therapeutic efficacy and side effect of various evidence-based programs. Methods Key words were defined as multiple sclerosis, immunomodulatory therapy and therapy, etc. We searched MEDLINE, Cochrane Library, Wanfang data bases for Scientific Journals in China and National Knowledge Infrastructure for Chinese Scientific Journals Database. Additionally, we applied manual searching and screened out conference paper and academic dissertation, etc, from various references. After that we obtained and evaluated by Jadad scales on systematic reviews, randomized controlled trials, controlled clinical trials and observational study cases about glucocorticoids, plasmapheresis, intravenous immunoglobulin, IFN-β, glatiramer acetate, mitoxantrone, natalizumab, fingolimod. Results After screening, all seventeen selected resources included systematic reviews 6 articles, randomized controlled trials 7 articles, controlled clinical trials 2 articles, observational study cases 2 articles, among which fifteen articles were proved to be high quality (according to Jadad scoring system, five score 4, six score 5, four score 7, two chapters were judged to be low quality scoring 3. Finally, we summerize that: 1 The first choice of treatment for acute relapses is glucocorticoids and we suggest that plasmapheresis or intravenous immunoglobulin may be tried as an alternative therapy in acute MS relapse, especially in case of contraindications to intravenous methylprednisolone. 2 Immunomodulatory or immunosuppressive treatment (IFN-β, glatiramer acetate, mitoxantrone, natalizumab can be an option to prevent new relapses and progression of disability. 3 Fingolimod is an oral treatment for multiple sclerosis to improve treatment adherence. Conclusion Using evidence-based medicine methods can provide us best clinical evidence on MS treatment.

    CD40/CD40 ligand (CD40L) dyad, a co-stimulatory bi-molecular complex involved in the adaptive immune response, has also potent pro-inflammatory actions in haematopoietic and non-haematopoietic cells. We describe here a novel role for soluble CD40L (sCD40L) as modifier of glomerular permselectivity directly acting on glomerular epithelial cells (GECs). We found that stimulation of CD40, constitutively expressed on GEC cell membrane, by the sCD40L rapidly induced redistribution and loss of nephrin in GECs, and increased albumin permeability in isolated rat glomeruli. Pre-treatment with inhibitors of CD40-CD40L interaction completely prevented these effects. Furthermore, in vivo injection of sCD40L induced a significant reduction of nephrin and podocin expression in mouse glomeruli, although no significant increase of urine protein/creatinine ratio was observed after in vivo injection. The same effects were induced by plasma factors partially purified from post-transplant plasma exchange eluates of patients with focal segmental glomerulosclerosis (FSGS), and were blocked by CD40-CD40L inhibitors. Moreover, 17 and 34 kDa sCD40L isoforms were detected in the same plasmapheresis eluates by Western blotting. Finally, the levels of sCD40Lwere significantly increased in serum of children both with steroid-sensitive and steroid-resistant nephrotic syndrome (NS), and in adult patients with biopsy-proven FSGS, compared to healthy subjects, but neither in children with congenital NS nor in patients with membranous nephropathy. Our results demonstrate that sCD40L directly modifies nephrin and podocin distribution in GECs. Moreover, they suggest that sCD40L contained in plasmapheresis eluates from FSGS patients with post-transplant recurrence may contribute, presumably cooperating with other mediators, to FSGS pathogenesis by modulating glomerular permeability.

    Full Text Available Background: AB0-incompatible kidney transplantation is one of the ways to effectively expand the pool of living donors. In Russia, this technology has been used for more than 10 years, but until now there have been no reports on its long-term results. Aim: To evaluate the short- and long-term outcomes of the living-related AB0-incompatible kidney transplantations. Materials and methods: We analyzed the results of 49 consecutive AB0-incompatible kidney transplantations, performed from 2011 to 2017. Preoperative management of recipients included administration of rituximab and intravenous immunoglobulin, plasmapheresis and/or selective immunoadsorption, and combination of tacrolimus, mycophenolates and steroids. The target of anti-A/B antibody levels were is 1:8. All patients received standard immunosuppression after transplantation. Results: At baseline, median anti-A/B titer was 1:16 (1:2 to 1:1024 for IgM and 1:4 (0 to 1:512 for IgG. Median rituximab dose was 286 mg/m2 (range, from 94 to 396. To achieve target antibody levels, up to 10 plasmapheresis and/or immunoadsorption sessions (median, 2 were required. There were no deaths during the follow-up. Five grafts were lost, one of them due to hyperacute rejection. The incidence of biopsy-proven rejection was 6%. One-, three and six-year graft survival was 94%, 90% and 80%, respectively. Conclusion: Kidney transplantation across the AB0-incompatibility barrier is a  safe, successful and reasonable option to reduce the organ shortage.

    Severe hypertriglyceridemia has been consistently associated with an increased risk of cardiovascular disease and other complications, namely acute pancreatitis. We report a case of a 64 year-old woman with hypertrophic cardiomyopathy and metabolic syndrome with triglyceride level of 3260 mg/dL. Plasma exchange was performed with simultaneous medical treatment to achieve a rapid and effective lowering of triglycerides in order to prevent clinical complications. After three plasmapheresis sessions a marked reduction in triglyceride and total cholesterol levels was observed. Several cases have shown the importance of plasmapheresis in the treatment of acute pancreatitis. We intend to demonstrate the applicability of this technique as primary prophylaxis in the presence of extremely high serum triglyceridemia levels. Resumo A hipertrigliceridemia grave tem sido associada de forma consistente ao aumento do risco cardiovascular e a outras complicações, nomeadamente, pancreatite aguda. Descrevemos um caso de uma mulher de 64 anos, com miocardiopatia hipertrófica e síndrome metabólica com valor sérico de triglicerídeos de 3260 mg/dL. Foi efectuada plasmaferese e optimizado o tratamento médico para alcançar uma redução rápida e efectiva dos níveis dos triglicerídeos, prevenindo complicações clínicas. Após três sessões de plasmaferese, verificou-se uma redução marcada dos triglicerídeos e do colesterol total. Existem alguns casos descritos na literatura demonstrado a importância da plasmaferese no tratamento da pancreatite aguda em contexto de hipertrigliceridemia grave. Os autores pretendem com este caso demonstrar a aplicabilidade desta técnica em contexto de prevenção primária em doentes com níveis de triglicerídeos extremamente aumentados.

    A prospective iterative trial of proteasome inhibitor (PI)-based therapy for reducing HLA antibody (Ab) levels was conducted in five phases differing in bortezomib dosing density and plasmapheresis timing. Phases included 1 or 2 bortezomib cycles (1.3 mg/m(2) × 6-8 doses), one rituximab dose and plasmapheresis. HLA Abs were measured by solid phase and flow cytometry (FCM) assays. Immunodominant Ab (iAb) was defined as highest HLA Ab level. Forty-four patients received 52 desensitization courses (7 patients enrolled in multiple phases): Phase 1 (n = 20), Phase 2 (n = 12), Phase 3 (n = 10), Phase 4 (n = 5), Phase 5 (n = 5). iAb reductions were observed in 38 of 44 (86%) patients and persisted up to 10 months. In Phase 1, a 51.5% iAb reduction was observed at 28 days with bortezomib alone. iAb reductions increased with higher bortezomib dosing densities and included class I, II, and public antigens (HLA DRβ3, HLA DRβ4 and HLA DRβ5). FCM median channel shifts decreased in 11/11 (100%) patients by a mean of 103 ± 54 mean channel shifts (log scale). Nineteen out of 44 patients (43.2%) were transplanted with low acute rejection rates (18.8%) and de novo DSA formation (12.5%). In conclusion, PI-based desensitization consistently and durably reduces HLA Ab levels providing an alternative to intravenous immune globulin-based desensitization. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Full Text Available Background: Respiratory failure and crisis is one of major complications of thymectomy in myasthenia gravis patients. There are different medication regimes for preparing these patients for surgery and reducing post-operative side effects. The goal of this study is to compare respiratory complications of oral vs. Parenteral preoperative administration of anticholinesterase agents for thymectomy in myasthenia gravis patients. Methods: This randomized controlled trial included 101 patients in class IIA or IIB of myasthenia gravis according to the Osserman classification system. The control group fasted for eight hours before surgery and oral anticholines-terase agents were replaced with parenteral ones. The case group also fasted for 8 hours before surgery, but pyridostigmine was continued at its usual dose until the time of operation and the last dose was given to patients with a small amount of water in the operating room on the operating bed. Results: There was no statistically meaningful difference between the two groups in terms of age, sex and pathologic findings. In comparison, the mean hospital stay for the case group was 3.98 days and 6.34 for the control group (p value = 0.003. There were eight cases of respiratory crisis or failure (16% in the control group but only 1 case (2% was observed in case group (p value = 0.014. Only one patient in the case group required re-intubation after the surgery; however, six patients in control group were re-intubated (p value = 0.053. Plasmapheresis was required for five patients in the control group and one patient in the case group (p value = 0.098. Tracheostomy was performed on two patients in the control group to accommodate prolonged intubation, but none of the case group required this procedure. Conclusion: This study shows that continuing oral anticholinesterase agents up to the time of operation, with the last dose at the operative theater, lowers the incidence of post-operative myasthenia

    Full Text Available Se describe el caso de un varón de 47 años, con tiempo de enfermedad de dos días, caracterizado por pérdida de fuerza progresiva, simétrica y ascendente de miembros inferiores, se realizó punción lumbar luego de la tomografía cerebral y electromiografía lo cual evidenció polirradiculopatía motora pura con patrón axonal, compatible con el síndrome de Guillain Barré. Posteriormente, recibió cuatro sesiones de plasmaféresis, con mejoría clínica significativa desde la segunda sesión. Debido al antecedente epidemiológico se solicitó set para Brucellas, con rosa de Bengala positivo, se inició tratamiento antibiótico con rifampicina y doxiciclina, además de rehabilitación. Tres meses después el paciente mejoró completamente. La importancia del tratamiento temprano con plasmaféresis y determinar su diagnóstico etiológico hacen que el pronóstico del síndrome de Guillain Barré sea favorable.We describe a case of a 47 years old male, with a history of 2 days of progressive, ascendant, symmetrical weakness in the lower extremities; a lumbar puncture was performed after the brain CT scan, as well as an electromyography, evidencing pure motor polyradiculopathy with axonal pattern, compatible with Guillain Barre syndrome. Afterwards, he received four plasmapheresis sessions, with clinical improvement from the second session. Due to his epidemiological background, Brucella set testing was done. Rose Bengal was positive, antibiotic treatment with rifampin and doxicicline was initiated, as well as rehabilitation. Three months later the patient recovered completely. The relevance of early treatment with plasmapheresis and the definition of the etiologic diagnosis determine that the prognosis of the Guillain Barre syndrome is favorable.

    Therapeutic plasma exchange (TPE) is a generally accepted and frequently performed procedure for numerous therapeutic indications in adults. Slowly, TPE is also becoming more and more popular in the treatment of pediatric patients. Although, we know that TPE is safe in pediatric patients, the outcome of children treated with TPE is rarely reported. Furthermore, there are only general recommendations regarding the plasma replacement fluid for children and these are adopted from adults. Data concerning outcome and the influence of different types of replacement fluids on hemostasis in children are scarce. We retrospectively evaluated 324 TPE treatments performed in 35 patients between 2008 and 2013 in our level 4 institution for pediatric hematology and oncology. The plasmapheresis procedures were categorized into three groups based on the replacement fluid used. The first group received solvent/detergent-treated (S/D) plasma (70.0% of patients), the second group was administered 5% human albumin (7.7% of patients) and the third group was treated with a combination of human albumin 5% and S/D plasma (22.3% of patients). To assess hemostasis, data on INR, aPTT, fibrinogen and ATIII were collected before and after plasmapheresis from the patients' charts. A modified Multi Organ Dysfunction Syndrome (MODS) Index was used to classify organ failure. Patient outcome, survival rate and adverse events were evaluated. We found a significant increase in the INR by 35.83% and of the aPTT by 18.53% within the human albumin group. The INR and aPTT of patients allocated to the S/D plasma group decreased by 1.58% and 15.77% on average, respectively. The combination group revealed a mild increase of the INR (9.47%), accompanied by a reduction of aPTT (5.97%). Furthermore we found that the survival rate was significantly associated with a MODS Index of <2 (p<0.001). Overall, the number of adverse events was low (1.2%) and none of these were considered life-threatening. Hemostasis

    Full Text Available A 12-year-old girl with a history of steroid and cyclosporine (CsA resistant nephrotic syndrome owing to focal and segmental glomerulosclerosis (FSGS has progressed to end-stage renal disease (ESRD for which she underwent hemodialysis for 18 months before she successfully received a fully matched kidney transplant from her sister at the age of nine years. The post transplantation (Tx period was marked by an early and massive proteinuria indicating recurrent FSGS for which she received 12 sessions of plasmapheresis (PP; unfortunately, she did not appear to have any response to the PP therapy; thereafter, a conservative management comprising essentially enalapril and losartan has been initiated and was also not successful during the first four months, however, a very gradual response has been noticed to occur after five months of conservative therapy and ultimately, the patient attained complete remission after 21 months of treatment. Amazingly, 15 months after discontinuation of enalapril and losartan, she remained in a complete and sustained remission with a good renal allograft function. To the best of our knowledge, this is the first case ever reported in the literature of a "spontaneous" remission of post transplant recurrent FSGS.

    Full Text Available We present a woman referred with underlying non-Hodgkin's lymphoma (NHL masquerading clinically with Guillain-Barré syndrome (GBS like syndrome. At first evaluation, chest CT-Scan along with brain and whole spine MRI were normal. Electrodiagnostic studies were in favor of acute generalized polyradiculoneuropathy. Laboratory evaluation revealed hypoglycorrhachia. She treated with plasmapheresis after two weeks; she was discharged from hospital, but neurological recovery was not complete. After 6 months, she came back with acute onset of weakness in lower limbs, back pain, fever and urinary incontinence. Pinprick and light touch complete sensory loss was found beneath umbilicus. Thoracic MRI with contrast revealed a dorsal epidural mass extending smoothly from T8 to T12 (10 cm with spinal cord compression. She underwent urgent laminectomy for spinal cord decompression. Histological examination revealed small round cell tumor suggestive of malignant T-cell type lymphoma. In cases with Guillain-Barré syndrome presentation, systemic hematologic disorders such as non-Hodgkin's lymphoma should be considered as one of the differential diagnosis of underlying disease.

    2017-08-01

    Beyond the major advances produced by careful clinical-radiological phenotyping and biomarker development in autoimmune central nervous system disorders, a comprehensive knowledge of the range of available immune therapies and a deeper understanding of their action should benefit therapeutic decision-making. This review discusses the agents used in neuroimmunology and their mechanisms of action. First-line treatments typically include corticosteroids, intravenous immunoglobulin, and plasmapheresis, while for severe disease second-line "induction" agents such as rituximab or cyclophosphamide are used. Steroid-sparing agents such as mycophenolate, azathioprine, or methotrexate are often used in potentially relapsing or corticosteroid-dependent diseases. Lessons from adult neuroimmunology and rheumatology could be translated into pediatric autoimmune central nervous system disease in the future, including the potential utility of monoclonal antibodies targeting lymphocytes, adhesion molecules for lymphocytic migration, cytokines or their receptors, or complement. Finally, many agents used in other fields have multiple mechanisms of action, including immunomodulation, with potential usefulness in neuroimmunology, such as antibiotics, psychotropic drugs, probiotics, gut health, and ketogenic diet. All currently accepted and future potential agents have adverse effects, which can be severe; therefore, a "risk-versus-benefit" determination should guide therapeutic decision-making.

    Full Text Available An oncologic emergency is defined as any acute, potentially life-threatening event, either directly or indirectly related to a patient′s cancer (ca or its treatment. It requires rapid intervention to avoid death or severe permanent damage. Most oncologic emergencies can be classified as metabolic, hematologic, structural, or side effects from chemotherapy agents. Tumor lysis syndrome is a metabolic emergency that presents as severe electrolyte abnormalities. The condition is treated with aggressive hydration, allopurinol or urate oxidase to lower uric acid levels. Hypercalcemia of malignancy is treated with aggressive rehydration, furosemide, and intravenous (IV bisphosphonates. Syndrome of inappropriate antidiuretic hormone should be suspected if a patient with ca presents with normovolemic hyponatremia. This metabolic condition usually is treated with fluid restriction and furosemide. Febrile neutropenia is a hematologic emergency that usually requires inpatient therapy with broad-spectrum antibiotics, although outpatient therapy may be appropriate for low-risk patients. Hyperviscosity syndrome usually is associated with Waldenstrφm′s macroglobulinemia, which is treated with plasmapheresis and chemotherapy. Structural oncologic emergencies are caused by direct compression of surrounding structures or by metastatic disease. Superior vena cava syndrome is the most common structural oncological emergency. Treatment options include chemotherapy, radiation, and IV stenting. Epidural spinal cord compression can be treated with dexamethasone, radiation, or surgery. Malignant pericardial effusion, which often is undiagnosed in ca patients, can be treated with pericardiocentesis or a pericardial window procedure.

    Full Text Available Abstract Introduction Vasculitis has been reported in a few cases of chronic lymphatic leukemia and with granulocytic colony-stimulating factor therapy. Those with granulocytic colony-stimulating factor occurred after prolonged therapy and there was a rise in total leukocyte count unlike that in our patient who received just a single injection for the first time. Case presentation We report the case of a 64-year-old Egyptian man with chronic lymphatic leukemia who developed progressive cutaneous vasculitic lesions following injection of a single dose of a granulocytic colony stimulating factor before a third cycle of chemotherapy to improve neutropenia. This is an unusual case and the pathogenesis is not fully understood. Our patient was not on any medical treatment except for bisoprolol for ischemic heart disease. Although aggressive management with steroids, anticoagulation and plasmapheresis had been carried out, the condition was aggressive and the patient's consciousness deteriorated. A magnetic resonance imaging scan of his brain revealed multiple ischemic foci that could be attributed to vasculitis of the brain. Conclusion The aim of this case report is to highlight the importance of monitoring patients on granulocytic colony-stimulating factor therapy, especially in the context of other conditions (such as a hematological malignancy that may lead to an adverse outcome.

  3. Anti-glomerular basement membrane glomerulonephritis in an HIV positive patient: case report

    Eduardo José Bellotto Monteiro

    Full Text Available We report on a case of a patient with HIV infection, diagnosed 18 months prior to the development of an anti-glomerular basement membrane (anti-GBM rapidly progressive glomerulonephritis; this is probably the first report of such an association. A 30-year-old white man presented with elevation of serum creatinine (1.3 - 13.5 mg/dL within one month. At admission, the urinalysis showed proteinuria of 7.2 g/L and 8,000,000 erythrocytes/mL. Renal biopsy corresponded to a crescentic diffuse proliferative glomerulonephritis mediated by anti-GBM, and serum testing for anti-GBM antibodies was positive; antinuclear antibodies (ANA and anti-neutrophilic cytoplasmic antibodies (ANCA were also positive. The patient underwent hemodyalisis and was treated with plasmapheresis, cyclophosphamide and prednisone. The association described here is not casual, as crescentic glomerulonephritis is not common in HIV-positive patients, anti-GBM glomerulonephritis is rare and anti-GBM antibodies are frequently observed in HIV-positive subjects when compared to the overall population. Based on the current case and on the elevated frequency of the positivity for such antibodies in this group of patients, it is advisable to be aware of the eventual association between these two conditions and to promote an active search for anti-GBM antibodies and early diagnosis of eventual urinary abnormalities in HIV-positive subjects, considering the severity of anti-GBM glomerulonephritis.

  4. Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN): could retinoids play a causative role?

    Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are overlapping manifestations on a spectrum of acute drug-induced conditions associated with severe blistering, skin peeling, and multi-organ damage. TEN is an eruption resembling severe scalding, with ≥30% skin detachment. SJS is a mild form of TEN, characterized histologically by epidermal keratinocyte apoptosis with dermo-epidermal separation and extensive small blisters with <10% body surface skin detachment. The syndrome can be induced by numerous medications and typically occurs 1-4 weeks after the initiation of therapy. Granulysin is found in the lesions of patients with SJS/TEN and plays a significant pathogenic role in the condition, but the overall mechanisms linking medications, granulysin, and disease manifestations remain obscure. This paper reviews evidence suggesting that the different medications implicated in SJS/TEN have the common property of interacting and synergizing with endogenous retinoids (vitamin A and its congeners), in many instances causing the latter to accumulate in and damage the liver, the main storage organ for vitamin A. It is hypothesized that liver damage leads to the spillage of toxic retinoid compounds into the circulation, resulting in an endogenous form of hypervitaminosis A and cytotoxicity with widespread apoptosis, mediated by granulysin and recognized as SJS/TEN. Subject to testing, the model suggests that symptom worsening could be arrested at onset by lowering the concentration of circulating retinoids and/or granulysin via phlebotomy or plasmapheresis or by pharmacological measures to limit their expression.

    Myasthenia gravis is an autoimmune disorder of peripheral nervous system, leading to fluctuating muscle weakness. It is caused by circulating antibodies that block acetylcholine nicotinic postsynaptic receptors at the postsynaptic neuromuscular junction. Myasthenic crisis is a life-threatening complication, which is defined as weakness from acquired myasthenia gravis. In this paper we described a 15-year-old boy who was admitted to the Paediatric Intensive Care Unit due to myasthenic crisis. He had suffered not only from myasthenia gravis but also hypothyroidism, cerebral palsy and epilepsy. The patient required mechanical ventilation and was successfully treated with both plasmapheresis and intravenous immunoglobulins. He recovered from the crisis and then thymectomy was performed. Perioperative period and anaesthesia passed uncomplicated. Discharged home from the hospital after 2.5 month-treatment, for the last 4 years, he has only come on scheduled outpatient medical appointments. This case reveals that myasthenic crisis, albeit rare, may occur in male adolescents. In such cases multidisciplinary care followed by surgery becomes a procedure of choice. Concomitant medical problems, if well controlled, do not affect the results of outcome of the underlying disease.

  6. Managing hypertriglyceridemia in children with systemic lupus erythematosus: Two sides of the same coin.

    Hypertriglyceridemia is common in children with systemic lupus erythematosus (SLE). A retrospective analysis of the baseline clinical-pathological presentation and treatment outcome (status of lipid profiles) was performed in two children with SLE, who presented with extreme hypertriglyceridemia over a follow-up period of four weeks. The children were treated with prednisolone, mycophenolate mofetil (MMF), hydroxychloroquine and hypolipidemic agents, depending on their disease status. On serial follow-up, the first child showed a significantly raised serum triglyceride level after receiving one week of oral prednisolone therapy. Anti-lipoprotein-lipase (LPL) autoantibody was absent. Lipid profile levels of this child gradually improved after replacing oral prednisolone with another immunosuppressant, namely MMF. The second child presented with extreme hypertriglyceridemia with positive anti-LPL autoantibody. She responded to plasmapheresis followed by increasing the dose of immunosuppressant. So, extreme hypertriglyceridemia in children with SLE may be steroid induced or due to presence of anti-LPL auto antibody. Management should be individualized depending on the etiology.

    Full Text Available Background: Thrombocytopenia is an important cause of bleeding. Different clinical conditions associated with thrombocytopenia and their reflections to the hemostatic table will be examined in this study. Methods: A total of 100 patients with thrombocytopenia who were treated in Hacettepe University between 1993 and 2013, 29 with thrombotic thrombocytopenic purpura (TTP, 36 with immune thrombocytopenic purpura (ITP, and 35 with aplastic anemia (AA, were included in the study. Clinical features and laboratory values were reviewed. Results: Thrombosis, fever, and sepsis were more frequently seen in TTP. The most common bleeding type was subcutaneous bleeding in all patient groups. Among patients with TTP, twenty-five patients (86, 2% had fever, 26 patients (89, 7% had a neurologic disorder, and 16 patients (55, 1% had renal dysfunction. Regarding the diagnostic criteria of TTP, 13 patients (44, 8% met five, 12 (41, 4% patients met four and 4 (13, 8% patients met three criteria. The median session of plasmapheresis was 17 (range; 2-127. There was no relation between session count and remission (p=0.28. Conclusion: The severity of clinical presentation and underlying disorders are the most important points with which to approach patients with thrombocytopenia. Clinical reflections may help to identify the cause of thrombocytopenia but not sufficiently demonstrative for diagnosis. [J Contemp Med 2017; 7(4.000: 316-322

    A 28-year-old Japanese male without a significant past medical history presented with new-onset generalized clonic seizure and headache. A brain MRI revealed multiple enhanced lesions on both cerebral hemispheres. Laboratory exams showed no evidence of systemic inflammation or auto-immune antibodies such as ANCAs. Despite four courses of high-dose methylprednisolone pulse therapy and five treatments with plasmapheresis, his symptoms worsened and the MRI lesions progressed rapidly. During these treatments, we performed a targeted brain biopsy, that revealed histological findings consistent with a predominant angiitis of parenchymal and subdural small vessels. He was provided with diagnosis of central nervous system vasculitis (CNSV). Subsequent cyclophosphamide pulse therapy enabled a progressive successful improvement of his symptoms. While diagnostic methods for CNSV remain controversial, histological findings are thought to be more useful in obtaining a more definitive diagnosis than findings in image studies, such as MRI and angiography. We suggest that a brain biopsy should be considered during the early period of cases with suspected CNSV and rapid clinical deterioration. We also detected human herpesvirus 7 (HHV-7) using PCR technology in brain biopsy specimens, however the relationship between CNSV and HHV-7 infection is unknow.

    Full Text Available We report a case of a 13-year-old girl with acute lymphoblastic lymphoma- leukemia, who presented with a cardiac metastasis in the right ventricle, resulting in a pulmonary embolism. At the time of her leukemia diagnosis, a cardiac mass was incidentally found. The differential diagnosis for this unusual cardiac mass included cardiac tumor, metastasis, vegetation, and thrombus. Empirical treatment was initiated, including anticoagulation and antibiotics. She underwent plasmapheresis and was administered oral prednisolone for her leukemia. Five days later, she experienced sudden hemodynamic collapse and required extracorporeal membrane oxygenation insertion and emergency surgery. These interventions proved futile, and the patient died. Pathology revealed that the cardiac mass comprised an aggregation of small, round, necrotic cells consistent with leukemia. This is the first known case of acute lymphoblastic leukemia presenting as a right ventricular mass, with consequent fatal acute pulmonary embolism. A cardiac mass in a child with acute leukemia merits investigation to rule out every possible etiology, including vegetation, thrombus, and even a mass of leukemic cells, which could result in the fatal complication of pulmonary embolism.

    Hemophagocytic syndrome (HPS) is mainly characterized by massive infiltration of bone marrow by activated macrophages and often presents with pancytopenia. Thrombotic microangiopathy (TMA) is also present with thrombocytopenia and renal involvement. Both conditions could coexist with each other and complicate the condition. Directory of Open Access Journals (DOAJ), EMBASE, Google Scholar, PubMed, EBSCO, and Web of Science with keywords relevant to; Hemophagocytic syndrome, macrophage activation syndrome, interferon-gamma and thrombotic microangiopathy, have been searched. Viral infection, rheumatologic disease and malignancies are the main underlying causes for secondary HPS. calcineurin inhibitors and viral infections are also the main underlying causes of TMA in transplant recipients. In this review, we discussed a 39-year-old male who presented with pancytopenia and renal allograft dysfunction. With the diagnosis of HPS induced TMA his renal condition and pancytopenia improved after receiving intravenous immunoglobulin (IVIG) and plasmapheresis therapy. HPS is an increasingly recognized disorder in the realm of different medical specialties. Renal involvement complicates the clinical picture of the disease, and this condition even is more complex in renal transplant recipients. We should consider the possibility of HPS in any renal transplant recipient with pancytopenia and allograft dysfunction. The combination of HPS with TMA future increases the complexity of the situation.

    Full Text Available Primary Sjorgen syndrome is one of the commonest autoimmune diseases with characteristic of involvement of lachrymal and salivary glands, but other organ involvements as peripheral and central nervous system are also possible. The reported case is a 23 year old lady presented with progressive sensory ataxia and weakness of four limbs, bilateral sensory hearing loss and cognitive impairment with minimental score equal to 15/30 since one year prior to admission with associated bilateral central corneal opacity, dry mouth and dry eyes. Electro physiologic studies showed sensory motor axonal polyneuropathy . A biopsy of sural nerve and salivary glands of lower lip showed lymphocytic infiltration. Serologic evidence showed positive Anti Ro (SS-B, negative HCV and HIV antibody, thereafter the diagnosis was confirmed and according to this diagnosis she received high dose of intravenous methyl prednisolon then both hearing loss and cognitive impairment improved partially (minimental score 21/30 . At last, she underwent plasmapheresis and her sensory ataxia improved greatly.

  12. Postulated Role of Vasoactive Neuropeptide-Related Immunopathology of the Blood Brain Barrier and Virchow-Robin Spaces in the Aetiology of Neurological-Related Conditions

    Directory of Open Access Journals (Sweden)

    D. R. Staines

    2008-01-01

    Full Text Available Vasoactive neuropeptides (VNs such as pituitary adenylate cyclase-activating polypeptide (PACAP and vasoactive intestinal peptide (VIP have critical roles as neurotransmitters, vasodilators including perfusion and hypoxia regulators, as well as immune and nociception modulators. They have key roles in blood vessels in the central nervous system (CNS including maintaining functional integrity of the blood brain barrier (BBB and blood spinal barrier (BSB. VNs are potent activators of adenylate cyclase and thus also have a key role in cyclic AMP production affecting regulatory T cell and other immune functions. Virchow-Robin spaces (VRSs are perivascular compartments surrounding small vessels within the CNS and contain VNs. Autoimmunity of VNs or VN receptors may affect BBB and VRS function and, therefore, may contribute to the aetiology of neurological-related conditions including multiple sclerosis, Parkinson's disease, and amyotrophic lateral sclerosis. VN autoimmunity will likely affect CNS and immunological homeostasis. Various pharmacological and immunological treatments including phosphodiesterase inhibitors and plasmapheresis may be indicated.

  13. Serum suPAR in patients with FSGS: trash or treasure?

    The urokinase-type plasminogen activator receptor (uPAR) has important functions in cell migration. uPAR can be shed from the cell membrane resulting in soluble uPAR (suPAR). Further cleavage gives rise to shorter fragments with largely unknown functions. Recent studies have demonstrated that both overexpression of uPAR on podocytes and the administration of suPAR cause proteinuria in mice. The common pathogenic mechanism involves the activation of podocyte β3-integrin. Increased activation of β3-integrin is also observed in patients with focal and segmental glomerulosclerosis (FSGS). These observations form the basis for the hypothesis that suPAR may be the circulating factor causing FSGS. A recent study fosters this idea by demonstrating increased suPAR levels in the serum of patients with FSGS and reporting an association with recurrence after transplantation and response to plasmapheresis. However, this study was heavily biased, and subsequent studies have given conflicting results. Although the experimental work is very suggestive, at present there is no proof that any known human suPAR fragment causes FSGS in humans. We therefore suggest that the measurement of suPAR using currently available assays has absolutely no value at the present time in decision-making in routine clinical practice.

    We obtained results of lung immune complexes (LIC), circulating immune complexes (CIC), 48-hour gallium lung scans (scans), bronchoalveolar lavage (BAL), and pulmonary function tests in 20 patients with idiopathic interstitial pneumonitis-fibrosis. Sixteen patients had predominantly interstitial (13 cases UIP) and/or intraalveolar (3 cases DIP) cellular disease (group 1). Prior to corticosteroid therapy in group 1, scans were positive in 75 percent, CIC were elevated in 86 percent, LIC were present in 64 percent, and BAL was abnormal in 90 percent. Duration of follow-up after treatment was 3.5 +/- 1.0 year. In group 1 after treatment with corticosteroids in 13 patients and corticosteroids and penicillamine (three patients) and plasmapheresis (one patient), only four patients remain stable or improved. After corticosteroid therapy, elevated CIC returned to normal values despite progressive patient deterioration. In three patients, lung immune complexes were still detected after circulating immune complexes had returned to normal after corticosteroid therapy. In group 2 were four patients with fibrotic disease; scans and CIC were uniformly negative, LIC were weakly present in only one patient, and BAL was abnormal in all. Despite corticosteroid therapy, all have died or deteriorated. These results suggest that positive gallium lung scans, BAL, circulating immune complexes, and to a lesser extent, lung immune complexes are associated with the cellular phase of interstitial pneumonia, but do not reliably identify a corticosteroid-responsive group

    We investigated the effect of implementing adaptive plasma ordering criteria in the computerized physician order entry (CPOE) system, with alerts that were automatically generated if the recipient's antecedent international normalized ratio (INR) did not meet the institutional criteria. In a regional health care system consisting of 11 hospitals using a common CPOE, data on the number of plasma orders and alerts that were generated were collected over a 4-month period before prescribers were required to select an indication for plasma. When adaptive ordering was implemented prescribers had to choose from prepopulated indications for plasma: INR of 1.6 or greater with bleeding, INR of 1.6 or greater before an invasive procedure, therapeutic exchange, massive transfusion, and other. Regardless of the antecedent INR the alert did not trigger if massive transfusion or plasmapheresis was selected. Information on prescribers and recipients was collected during this 5-month period. In the 4-month period before the adaptive alerts were implemented, 42.9% of the plasma orders generated an alert; in the 5-month period thereafter the alert rate was significantly lower at 27.9% (p plasma orders were for periprocedure or bleeding patients whose antecedent INR was less than 1.6. There were significant differences in prescriber specialties among those who ordered plasma using the other indication compared to all plasma orders. Electronic interventions improve compliance with plasma guidelines but as implemented are not sufficient to completely curtail non-evidence-based ordering. © 2013 American Association of Blood Banks.

    Pemphigoid and pemphigus diseases as well as Stevens-Johnson syndrome present as vesiculobullous disorders of the skin and may additionally involve both the oral cavity and the ocular surface. Ocular involvement ranges from mild irritation and dry eye disease to chronic conjunctivitis, symblepharon, eyelid malposition, ocular surface scarring and severe visual loss. In addition to diagnostic assessments, ophthalmologists must treat the dry eye and meibomian gland dysfunction components of these diseases using a stepladder approach, including eyelid hygiene and lubricants. Topical anti-inflammatory therapy is used to treat acute inflammatory exacerbations of the ocular surface, but it cannot prevent scarring alone. Intralesional antimetabolite therapy can cause regression of conjunctival pathology in selected cases. Hence, patients with vesiculobullous disorders should be managed by a multidisciplinary team representing ophthalmology, dermatology, otolaryngology, oral medicine and pathology, internal medicine and intensive care. Systemic treatments including corticosteroids, azathioprine, cyclophosphamide, cyclosporine and mycophenolate mofetil help control inflammation. Intravenous immunoglobulins, plasmapheresis and targeted antibody therapy can be used in selected, severe and treatment-resistant cases. Local surgical management may include debridement of pseudomembranes, lysis of symblepharon, amniotic and mucous membrane grafting as well as reconstructive procedures. Prospective, multicentre, international studies are recommended to further support evidence-based practice. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Patients with thrombotic thrombocytopenic purpura (TTP), Moschowitz's disease, run a high risk of perioperative bleeding and need intensive hematologic support. In some patients, TTP is associated with cancer but the surgical role in these patients is still unclear. To illustrate the surgical problems and outcome we present the case histories of three patients with TTP observed in our emergency department. Two patients had TTP secondary to cancer and one patient with primary TTP (no evidence of neoplasia) had emergency operation for gastric hemorrhage, occlusion and TTP unresponsive to plasmapheresis. The first two patients who had not radical resection of cancer and no splenectomy, died for TTP complications. The third patient who underwent emergency splenectomy, had an uneventful postoperative course and TTP completely regressed. These case reports suggest that patients with TTP should be screened to rule out cancer. In patients with acute cancer-related complications emergency surgery should aim to resect the cancer. An associated splenectomy may increase the effectiveness of postoperative hematologic therapy.

    The presence of circulating plasma factors (PF) altering renal permeability to proteins has been previously described in patients with focal segmental glomerulosclerosis (FSGS). Since these patients show reduced nephrin and podocin expression at renal biopsy, we evaluated the effect of serum and PF from patients with FSGS on nephrin and podocin expression in human podocytes. We studied 7 sera from patients with steroid-resistant FSGS, 3 from patients with nephrotic syndrome caused by non-immune disease, and 6 from healthy subjects. PF was prepared from plasmapheresis eluates of 2 patients with post-transplant recurrence of FSGS. Purification procedure was based on protein A Sepharose chromatography and differential precipitation in ammonium sulphate. Nephrin and podocin expression was semi-quantitatively evaluated by immunofluorescence. We found that serum and PF from FSGS patients rapidly induced redistribution and loss of nephrin in podocytes. This effect was associated with cytoskeleton redistribution and inhibited by cytochalasin B and sodium azide. On the contrary, podocin expression was unchanged after incubation with serum and PF from FSGS patients for short periods, but markedly reduced at 24 h. Our results demonstrate that serum and PF from FSGS patients may directly affect nephrin and podocin in human podocytes, thus providing new insights into the mechanisms causing proteinuria in FSGS.

    Full Text Available The serious shortage of cadaveric organs has prompted the development of ABO-incompatible live donor renal transplantation. We report our experience of the initial two live donor ABO incompatible renal transplants at our hospital. The first patient was a 55-year-old type A female who received a kidney from her AB type husband. The second patient was a 27-year-old type O male who received renal transplantation from his type A father. Preconditioning immunosuppressive therapy in the two patients with tacrolimus, mycophenolate mofetil and methylprednisolone was started 7 days before transplantation. During the period of preconditioning, double filtration plasmapheresis (DFPP was employed to remove anti-A and -B antibodies. Laparoscopic splenectomy and renal transplantation were performed after the anti-donor ABO antibodies were reduced to a titer of 1:4. Rituximab, a humanized monoclonal anti-CD20 antibody, was administered to the second patient due to a rebound in the anti-A antibody titer during the preconditioning period. Under a tacrolimus-based immunosuppressive regimen, both patients recovered very well without any evidence of rejection. Serum creatinine levels were 1.0 and 1.4 mg/dL at 6 and 3 months after transplantation, respectively. These cases illustrate that with new immunosuppressive agents, DFPP and splenectomy, ABO-incompatible renal transplantation can be successfully conducted in end-stage renal disease patients whose only available live donors are blood group incompatible.

    Full Text Available Pruritus can be a prominent symptom  in patients with chronic liver disorders, especially those  with cholestasis,  and  substantially  affects  quality  of life. Management of pruritus  in cholestatic  liver diseases  remains  a  complicated   medical  problem. The review article deals with pathophysiological mechanisms of pruritus in cholestatic liver diseases, in particular, with the role of bile acids, endogenous opioids, serotonin, and histamine. There is new data on the key pathophysiological elements, such as neuronal activation lysophosphatidic acid and autotaxin, an enzyme that produces lysophosphatidic acid and whose serum activity is associated with the intensity of pruritus. Pathophysiology-based management approaches include administration of anionic exchange resin cholestyramine, ursodeoxycholic acid, rifampicin agonists, an opioid antagonist naltrexone and a  serotonin-reuptake inhibitor sertraline. These agents are recommended for the use as a stepped treatment algorithm. Patients who do not respond to these therapies can become candidates for albumin dialysis, plasmapheresis, ultraviolet B phototherapy, or need some other individualized approaches. New knowledge on the pathophysiology of pruritus may potentially result in the development of new agents for cholestatic pruritus.

  2. [Severe hypertriglyceridemia--an important cause of pancreatitis].

    2008-05-01

    Moderate hypertriglyceridaemia is a risk factor for cardiovascular disease and serious hypertriglyceridaemia, with triglyceride values above 10 mmol/L, increases the risk of pancreatitis. Gallstones and alcohol abuse are regarded as the two most important causes of acute pancreatitis, but the considerable risk posed by hypertriglyceridaemia has probably been underrated. It is therefore crucial to acquire updated knowledge and awareness of the fact that high levels of triglycerides can cause pancreatitis. This article is based on current literature retrieved though a search on the topic and clinical experience. Serious hypertriglyceridaemia is a relatively rare condition and its usual cause is genetic predisposition combined with obesity, diabetes or alcohol abuse. Certain types of medication, as well as pregnancy, are also well known causes. Current literature suggests that hypertriglyceridaemia is the cause of pancreatitis in 1-38% of the cases--a substantial variation. The condition is often accompanied by low amylase values and may therefore be underrated as a cause. Our case reports illustrate that the etiology is complex. Plasmapheresis or LDL-apheresis may be indicated when conservative treatment proves insufficient.

    Hepatocellular carcinoma with bile duct tumor thrombus is considered an aggressive malignancy, and the prognosis of liver transplant for it remains obscure. A 42-year-old man with recurrent hepatocellular carcinoma and a history of surgical resection was admitted to our hospital with a 10-day history of yellowish urine and itchy skin. There were 3 lesions in the right lobe with the diameter of 2 cm each. A mass was found in the upper part of common bile duct, and the intrahepatic bile duct was dilated. His serum alpha-fetoprotein level was 2476 μg/L, total bilirubin level was 327 μmol/L, direct bilirubin level was 261 μmol/L, and alanine aminotransferase was 714 U/L. There was no main portal vein thrombus or extrahepatic metastases. Because of his poor liver function, he was listed for a liver transplant. During the wait (30 d), he underwent 9 episodes of plasmapheresis to decrease the serum level of bilirubin. He had an orthotopic liver transplant with the graft from a deceased donor. After the liver transplant, he received 5 cycles of chemotherapy with the regimen of oxaliplatin and 5-fluorouracil. This patient has survived without recurrence of hepatocellular carcinoma for more than 82 months and remains in good condition. Liver transplant may have a favorable result for hepatocellular carcinoma patient with a bile duct tumor thrombus, within the Milan criteria.

    Full Text Available Abstract Background Pulmonary-renal syndrome associated with anti-glomerular basement membrane (GBM antibodies, also known as Goodpasture's syndrome, is a rare but acute and life-threatening condition. One third of patients presenting as anti-GBM antibody positive pulmonary-renal syndrome or rapidly progressive glomerulonephritis are also tested positive for anti-neutrophil cytoplasmic antibodies (ANCA. Whilst anti-GBM disease is considered a non-relapsing condition, the long-term course of double-positive patients is less predictable. Case Presentation We report a patient with such dual positivity, who presented with pulmonary hemorrhage, crescentic glomerulonephritis and membranous nephropathy. Plasmapheresis in combination with immunosuppresive therapy led to a rapid remission but the disease relapsed after two years. The serum of the patient was tested positive for antibodies to human lysosomal membrane protein 2 (hLAMP2, a novel autoantigen in patients with active small-vessel vasculitis (SVV. The anti-hLAMP2 antibody levels correlated positively with clinical disease activity in this patient. Conclusion We hypothesize that this antibody may indicate a clinical course similar to ANCA-associated vasculitis in double-positive patients. However, this needs to be confirmed on comprehensive patient cohorts.

  5. A case of severe encephalitis while on PD-1 immunotherapy for recurrent clear cell ovarian cancer

    2018-05-01

    Full Text Available Recurrent clear cell ovarian carcinoma is a difficult to treat condition and early trial data has suggested a possible role for immune checkpoint inhibitors. Nivolumab is an anti-PD-1 immunotherapy that has been used in this setting. While immune related toxicity of these agents has been well described, the occurrence of immune specific neurotoxicity is thought to be rare. We present a case of severe encephalitis while on PD-1 immunotherapy for a recurrent ovarian clear cell cancer and we believe this to be the first such reported case associated with the use of PD-1 inhibitor monotherapy. In this case, a 64-year-old woman with persistent clear cell ovarian cancer on Nivolumab presented with a severe fever of unknown origin and delirium; initial imaging and diagnostic work-up suggested a neurological etiology, but with no clear source. We concluded that this was a severe case of immune related encephalitis, thought to be brought about by the anti-PD-1 immunotherapy which responded well to systemic corticosteroids and plasmapheresis and the patient able to make a full recovery. We present a summary of the case and its management as well as a review of the literature on the previously reported neurotoxicity's of PD-1 inhibitors.

    Hemolytic disease of the fetus and newborn caused by anti-G antibodies is rare, and in most previously reported cases, leads to a mild anemia. The RhG antigen is usually found in association with both RhD and RhC. We report a case of a twin pregnancy affected by both anti-G and anti-C alloantibodies leading to severe hemolytic disease of the fetus and newborn requiring multiple intrauterine transfusions and prolonged postnatal therapy. A patient with a prolonged history of previously affected pregnancies due to anti-D and anti-C was subsequently found to be affected with anti-G instead. She required aggressive therapy during her pregnancy, initially with intravenous immune globulin and plasmapheresis until umbilical blood sampling and intrauterine transfusions were feasible. Although hemolytic disease of the fetus and newborn due to anti-G antibodies is rare and usually mild, these pregnancies should be followed up closely and in utero therapy should be offered if necessary.

  7. Thyroid-associated Ophthalmopathy

    Full Text Available Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves’ disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. There is an increased volume of extraocular muscles, orbital connective and adipose tissues. Clinical findings of thyroid-associated ophthalmopathy are soft tissue involvement, eyelid retraction, proptosis, compressive optic neuropathy, and restrictive myopathy. To assess the activity of the ophthalmopathy and response to treatment, clinical activity score, which includes manifestations reflecting inflammatory changes, can be used. Supportive approaches can control symptoms and signs in mild cases. In severe active disease, systemic steroid and/or orbital radiotherapy are the main treatments. In inactive disease with proptosis, orbital decompression can be preferred. Miscellaneous treatments such as immunosuppressive drugs, somatostatin analogs, plasmapheresis, intravenous immunoglobulins and anticytokine therapies have been used in patients who are resistant to conventional treatments. Rehabilitative surgeries are often needed after treatment.

    This is a retrospective study of the clinicopathological characteristics of 50 systemic lupus erythematosus patients with nephritis who underwent a kidney biopsy and were admitted to the American University of Beirut Medical Center, in Lebanon, between 1979 and 1999. There were 43 females and seven males, with a median age of 24 y. Renal histology slides from these patients were assessed according to the World Health Organization classification, and were distributed as follows: class I (n = 3, 6%); class II (n = 14, 28%); class III (n = 11, 22%); class IV (n = 19, 38%); class V (n = 1, 2%); class VI (n = 2, 4%). All the patients received oral prednisone, in addition the following treatments were used: pulse intravenous (i.v.) cyclophosphamide (n = 23, 46%); azathioprine (n = 22, 44%); pulse i.v. steroids (n = 19, 38%); chloroquine sulfate (n = 17, 34%); methotrexate (n = 5, 10%); and plasmapheresis (n = 2, 4%). The median duration of follow-up was 5 y (range 1-33 y). On their last evaluation, out of 37 patients who were followed, 20 patients (54%) had controlled disease, eight patients (22%) were still on active medical treatment, four patients (11%) were on chronic hemodialysis, and five patients (13%) had died. Unlike three other Arab populations studies from Kuwait, United Arab Emirates and Saudi Arabia, where the most frequent histopathologic abnormality was class III, diffuse proliferative LN (class IV) was the most common type of lupus nephritis in Lebanon, similarly to reports from USA, France, Netherlands, South Africa, Thailand and Taiwan.

    Neuromyelitis optica (Devic's disease) is an inflammatory demyelinating disease of the central nervous system that mainly affects spinal cord, optic nerve and brain regions with high aquaporin 4 antigen expression. This is a severe autoimmune disease caused by autoantibodies directed against aquaporin 4 and associated with high morbidity and mortality. Unlike other inflammatory conditions such as multiple sclerosis or rheumatoid polyarthritis, pregnancy does not seem to influence the activity of neuromyelitis optica, hence the need for a thorough treatment during pregnancy. Corticosteroid therapy is the treatment of choice for neuromyelitis optica during pregnancy. Other treatments may also be used including rituximab, some immunosuppressive agents and immunoglobulins. Immunosuppressive treatment or rituximab is recommended when the long-term corticosteroid treatment is contraindicated, in case of inefficiency or if side effects are intolerable. Immunoglobulins are administered to patients with serious outbreaks of neuromyelitis optica which do not respond to bolus methylprednisolone. Immunoglobulins alone can also be continued at a dose of 0.4 g/kg/day for 6-8 weeks until delivery. Plasmapheresis is also a good alternative to bolus methylprednisolone when outbreaks are extremely severe.

    A concentrate of mononuclear bone marrow cells is often desired for ex vivo treatment with pharmacologic agents, monoclonal antibodies, cytokines, and other agents prior to transplantation. A method has been developed for automated separation of mononuclear cells from large volumes of harvested bone marrow. A programmable instrument originally designed for clinical ex vivo cell separation and the plasma-pheresis of patients and blood donors was adapted to permit rapid preparation, in a closed sterile system, of a bone marrow product enriched with mononuclear cells. A mean (+/- SEM) of 53 +/- 30 percent of the original mononuclear cells was recovered in a volume of 125 +/- 42 mL containing 82 +/- 12 percent mononuclear cells. This technique removed 95 +/- 9 percent of the red cells in the original marrow. No density gradient materials or sedimenting agents were employed in this process. Of 36 marrows processed by this technique, 19 autologous (6 of which were purged with 4-hydroperoxycyclophosphamide) and 7 allogeneic marrows have been transplanted, with all evaluable patients achieving a neutrophil count of 0.5 x 10(9) per L in a mean (+/- SEM) of 21 +/- 6 days.

    The most common form of renal involvement in Sjögren's syndrome (SS) is tubulointerstitial nephritis. Renal dysfunction is usually mild and subclinical. Glomerulonephritis (GMN) is rare in patients with SS. We report a 28-year-old multigravida patient with primary Sjögren's syndrome (pSS) and associated manifestations, who presented with acute renal failure in the 20th week of her fifth pregnancy. The complaints and clinical findings, positive Schirmer's test, findings of dry eye on ophthalmologic examination, and the salivary gland biopsy were compatible with SS. The patient exhibited no other clinical or laboratory findings indicative of other collagenous disease and/or rheumatoid arthritis. She refused renal biopsy, hesitating for fear of fetal loss; thus, based on the clinical and laboratory findings indicating rapidly progressive GMN and vasculitis, prednisolone, plasmapheresis, and one dose of cyclophosphamide were administered during the pregnancy. Hemodialysis five times weekly was performed. At the 28th week of gestation, she underwent a cesarean section due to early rupture of membranes and fetal distress. A healthy male boy was delivered. The renal biopsy performed 2 weeks after labor revealed mesangial proliferative glomerulonephritis. After the fourth cyclophosphamide treatment, her urinary output increased and she was discharged from the hemodialysis program. She remains in follow-up at our outpatient clinic free of hemodialysis for 4 months. This is the first report of mesangial proliferative GMN requiring dialysis in a pregnant pSS patient that has featured good maternal and fetal outcomes.

    Background . Renal-limited myeloperoxidase vasculitis with simultaneous rheumatoid arthritis is reported as a rare occurrence. Review of literature suggests that most patients had a diagnosis of rheumatoid arthritis for several years prior to presenting with renal failure from myeloperoxidase vasculitis. Case Presentation . A 58-year-old Caucasian male presented to the hospital experiencing malaise, fevers, decreased oral intake, nausea, and vomiting for one week duration. His past medical history consisted of newly diagnosed but untreated rheumatoid arthritis, hypertension, and non-insulin-dependent diabetes mellitus. He was found to have acute renal failure, proteinuria, and hypoglycemia. Standard therapy, including intravenous fluids, did not improve his acute renal failure. A vasculitis workup resulted in a positive myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA). Renal biopsy revealed crescentic glomerulonephritis (GN) pauci-immune type, suggestive of MPO-ANCA-associated vasculitis (MPO-AAV). Treatment consisted of prednisone, cyclophosphamide, and seven cycles of plasmapheresis, in addition to hemodialysis for uremia. Upon discharge, he received hemodialysis for another week and continued treatment with cyclophosphamide and prednisone. Conclusion . Patients with longstanding rheumatoid arthritis may develop renal failure due to nonsteroidal anti-inflammatory medication use and AA type amyloidosis; however, necrotizing glomerulonephritis with crescent formation has been rarely reported. This stresses the importance of early recognition and swift initiation of treatment.

    A previously healthy 36-year-old woman presented with visual hallucinations and acute psychosis manifested predominantly as hypersexuality. Laboratory testing demonstrated elevated free thyroxine levels, suppressed thyroid-stimulating hormone levels and presence of thyroid-stimulating immunoglobulin and thyroid peroxidase (TPO) antibodies consistent with Graves' disease. Despite achieving biochemical euthyroidism, she remained profoundly hypersexual. She did not respond to additional treatment with antipsychotics and corticosteroids, prompting further evaluation. Cerebrospinal fluid analysis detected pleocytosis, elevated IgG, and presence of antibodies against anti-N-methyl-D-aspartate receptor (NMDAR), glutamic acid decarboxylase 65 and TPO. These results suggested a diagnosis of anti-NMDAR encephalitis. Prior to initiation of immunomodulator therapy, she was discovered to be pregnant with date of conception around the time of her original presentation. She received plasmapheresis with resolution of psychosis and decrease in free thyroxine levels. Graves' disease remitted during the remainder of the pregnancy but relapsed 5 months post partum. She has not had further neuropsychiatric symptoms. 2015 BMJ Publishing Group Ltd.

    Full Text Available Pemphigus is an autoimmune blistering disease affecting skin and mucous membranes which threatens the life. In our country it is the most common disease in this group. In our region, among the pemphigus cases, the most common variant is pemphigus vulgaris. Pemphigus vulgaris consists of the 80% of pemphigus cases and it occurs 10 times more than pemphigus foliaceus. Treatment of pemphigus is accepted as a miracle in clinical medicine. The disease, which had an almost always fatal outcome, had been turned to the disease which long-term remissions or “cure” can be achievable. However, in the past the cause of the death was the disease itself, nowadays, with decreasing frequency, all of the mortalities is due to the treatment side effects. In treatment of pemphigus which drug to use and when to use it has varieties according to the intended effect. Corticosteroids are the main treatment; besides IVIg, plasmapheresis or pulse steroid prefers to control the disease rapidly. Mainly immunosuppressive agents (azathioprine, methotrexate, cyclophosphamide, cyclosporine, and mycophenolate besides gold, dapsone, antibiotics or rituximab are using for late-term effect and to reduce the corticosteroid requirement.

    Full Text Available This retrospective study examined the incidence and factors influencing the occurrence of nonsocomial pneumonia (NP in a neuromedical intensive care unit (NICU. Of the 57 patients admitted to the NICU over one year, 26% developed nosocomial pneumonia. It was observed that the infected patients were significantly older than the noninfected (43+15 vs 22+18 years; p<0.001, had a longer NICU stay (33+31 vs 18+18 days: p=0.05 and needed longer duration of mechanical ventilation (20+25 vs 9 + 12 days: P<0.05. Patients with neuromuscular diseases had a trend towards higher incidence of NP than those with encephalopathy and therapeutic interventions such as plasmapheresis, blood transfusion and inotropic therapy did not influence the incidence of nosocomial pneumonia. The NICU mortality was not significantly influenced by nosocomial pneumonia. Pseudomonas aerugenosa was the predominant organism responsible for pneumonia. Nine percent of the tracheobronchial isolates were resistant to the routinely-tested antibiotics. In conclusion, nosocornial pneumonia is a common complication in a NICU and while it increases the duration of NICU stay, mortality appears to be uninfluenced.

  18. Anti-NMDA Receptor Encephalitis Presenting as an Acute Psychotic Episode in a Young Woman: An Underdiagnosed yet Treatable Disorder

    Full Text Available Anti-NMDA receptor (NMDAR encephalitis is a recently identified autoimmune disorder with prominent psychiatric symptoms. Patients usually present with acute behavioral change, psychosis, catatonic symptoms, memory deficits, seizures, dyskinesias, and autonomic instability. In female patients an ovarian teratoma is often identified. We describe a 32-year-old woman who presented with acute psychosis. Shortly after admission, she developed generalized seizures and deteriorated into a catatonic state. Although ancillary tests including MRI, electroencephalogram, and cerebrospinal fluid (CSF analysis were unremarkable, the presentation of acute psychosis in combination with recurrent seizures and a relentless course suggested autoimmune encephalitis. The patient underwent pelvic ultrasound which disclosed a dermoid cyst and which led to an urgent cystectomy. Plasmapheresis was then initiated, yielding partial response over the next two weeks. Following the detection of high titers of anti-NMDAR antibodies in the CSF, the patient ultimately received second line immunosuppressive treatment with rituximab. Over several months of cognitive rehabilitation a profound improvement was eventually noted, although minor anterograde memory deficits remained. In this report we call for attention to the inclusion of anti-NMDAR encephalitis in the differential diagnosis of acute psychosis. Prompt diagnosis is critical as early immunotherapy and tumor removal could dramatically affect outcomes.

    Full Text Available A 6-year-old child with Reye's syndrome was successfully treated in the Department of Pediatric Anaesthesiology and Intensive Care of the Ivano-Frankivsk Regional Children's Clinical Hospital. At admission to the hospital the child's condition was critical due to cerebral vascular insufficiency (semicoma, psychomotor agitation, endogenous intoxication syndrome, severe anemic syndrome (Hb — 78g/l, and coagulopathy. Due to the progression of type II respiratory failure, hepatic failure, hemorrhagic and anemic syndromes, and cerebral deficit tracheal intubation for the purpose of controlled ventilation was performed. In order to correct anemia, hypoproteinemia and hemorrhagic syndrome washed erythrocytes, a 10% albumin solution and fresh frozen plasma were transfused. Therapeutic bronchoscopy was performed due to the progression of the expectorant component secondary to ventilator!associated pneumonia. Nonspecific detoxification therapy with discrete plasmapheresis was used. On the 3rd day of treatment tracheal extubation was performed, on the 10th day the child was transferred to the gastroenterology department. On the 13th day of hospital stay in the gastroenterology department and on the 24th day of admission the child was discharged home in satisfactory condition.

    A 55-year-old patient with multiple myeloma (IgG-{lambda}) diagnosed in November 1988 was admitted because of bone pain throughout the body. After plasmapheresis and several courses of chemotherapy, a massive tumor of the left thoracic wall involving the rib appeared. Radiotherapy was performed to ameliorate the severe chest pain, after which myelomatous pleural effusion appeared on the left side. The serum, urine and pleural effusion revealed increased activity of amylase of the salivary type. Amylase activity was also detected in the supernatant of myeloma cells cultured from pleural effusion. We reviewed 12 cases of ectopic amylase-producing multiple myeloma. All the cases except one have been reported from Japan, and hyperamylasemia in these cases was detected at diagnosis or during course of the illness. Moreover, cytogenetic analysis of myeloma cells of previous reports revealed structural abnormalities including chromosome 1, near the amylase gene locus. This case also showed t (1; 10) (q21?; q26) by examination of 8 metaphase derived from bone marrow. These observations suggested that ectopic amylase production was induced by irradiation to the plasmacytoma of thoracic wall. (author).

    2012-01-01

    Full Text Available Neuromyelitis optica (NMO is an inflammatory disease of the central nervous system characterized by severe optic neuritis and transverse myelitis, usually with a relapsing course. Aquaporin-4 antibody is positive in a high percentage of NMO patients and it is directed against this water channel richly expressed on foot processes of astrocytes. Due to the severity of NMO attacks and the high risk for disability, treatment should be instituted as soon as the diagnosis is confirmed. There is increasing evidence that NMO patients respond differently from patients with multiple sclerosis (MS, and, therefore, treatments for MS may not be suitable for NMO. Acute NMO attacks usually are treated with high dose intravenous corticosteroid pulse and plasmapheresis. Maintenance therapy is also required to avoid further attacks and it is based on low-dose oral corticosteroids and non-specific immunosuppressant drugs, like azathioprine and mycophenolate mofetil. New therapy strategies using monoclonal antibodies like rituximab have been tested in NMO, with positive results in open label studies. However, there is no controlled randomized trial to confirm the safety and efficacy for the drugs currently used in NMO.

    Full Text Available Objective: to evaluate the efficiency of cytokine sorption with carbon with a locally aminocaproic acid-modified surface from the plasma of patients with general purulent peritonitis. Materials and methods. The material of the investigation was the plasma obtained during plasmapheresis in 10 patients with acute pancreatitis complicated by pancreonecrosis and general purulent peritonitis, which was used to estimate before and after sorption the content of the cytokines: interleukin (IL-1/8, IL-4, and IL-8 by enzyme immunoassay. The sorption properties of carbon hemosor-bent and aminocaproic acid-modified sorbent were comparatively evaluated. Results. Aminocaproic acid-induced modification of the carbon adsorbent surface with its further polycondensation results in the higher content of superficial functional groups (oxygen- and nitrogen-containing that enhance the hydrophility of the surface and the specific pattern of sorption, thus acting as a means for controlling and regulating the plasma concentration of regulatory proteins, primarily the proinflammatory cytokine IL-1^3, the chemokine IL-8 and the T-helper cell clone cytokine IL-4.

    Full Text Available Abstract Introduction Anti-glomerular basement membrane disease is a rare autoimmune disorder characterized by pulmonary hemorrhage, crescentic glomerulonephritis and the presence of circulating anti-glomerular basement membrane antibodies. The simultaneous occurrence of both anti-glomerular basement membrane disease and membranous nephropathy is rare. Case presentation A 59-year-old Hispanic man presented with acute onset of nausea and vomiting and was found to have renal insufficiency. Work-up included a kidney biopsy, which revealed anti-glomerular basement membrane disease with underlying membranous nephropathy. He was treated with emergent hemodialysis, intravenous corticosteroids, plasmapheresis, and cyclophosphamide without improvement in his renal function. Conclusion Simultaneous anti-glomerular basement membrane disease and membranous nephropathy is very rare. There have been 16 previous case reports in the English language literature that have been associated with a high mortality and morbidity, and a very high rate of renal failure resulting in hemodialysis. Co-existence of membranous nephropathy and anti-glomerular basement membrane disease may be immune-mediated, although the exact mechanism is not clear.

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

    Full Text Available Antibody-mediated rejection (ABMR is a major cause of late renal allograft dysfunction and graft loss. Risks and benefits of treatment of late ABMR have not been evaluated in randomized clinical trials. We report on a 35-year-old patient with deterioration in renal function and progressive proteinuria 15 years after transplantation. Recurrent infections after a splenectomy following traumatic splenic rupture 3 years earlier had led to reduction of immunosuppression. Renal transplant biopsy showed glomerular double contours, 40% fibrosis/tubular atrophy, peritubular capillaritis, and positive C4d staining indicating chronic-active ABMR. ABMR treatment was initiated with steroids, plasmapheresis, and rituximab. Fourteen days later, she presented to the emergency department with fever, diarrhea, vomiting, and hypotension. Despite antibiotic treatment she deteriorated with progressive hypotension, capillary leak with pleural effusion, peripheral edema, and progressive respiratory insufficiency. She died due to septic shock five days after admission. Blood cultures showed Streptococcus pneumoniae, consistent with a diagnosis of overwhelming postsplenectomy infection syndrome, despite protective pneumococcus vaccination titers. We assume that the infection was caused by one of the strains not covered by the Pneumovax 23 vaccination. The increased immunosuppression with B cell depletion may have contributed to the overwhelming course of this infection.

    Full Text Available Objective: to evaluate the efficiency of extracorporeal detoxification techniques in patients with abdominal sepsis. Subjects and methods. Three hundred and seventy-nine patients with acute generalized peritonitis were examined. Extracorporeal detoxifying techniques were used during conventional therapy in Group 1 (n=319; the other patients received only traditional therapy (a control group. The time course of changes in the parameters of toxemia, a hemostasiogram, and an immunogram were examined. Results. The study indicated significantly reduced endotoxemia and better blood aggregation resulting from the use of plasmapheresis, cryoplasmasorption, and plasmasorption, as well as stimulated immunity when the above techniques were combined with autoblood photomodification and extracorporeal immunopharmacotherapy in patients with abdominal sepsis. In severe abdominal sepsis and infectious-toxic shock, there was regression of multiple organ dysfunction and lower mortality when venovenous hemofiltration was applied. Conclusion. A differential approach to using active detoxifying techniques is needed, by taking into account the severity of the disease. Key words: abdominal sepsis, detoxifying techniques.

    2005-01-01

    Full Text Available A differential approach to choosing the methods of extracorporeal detoxification in the complex treatment of abdominal sepsis in the context of endogenous intoxication in order to enhance the efficiency of medical measures was pathogeneti-cally substantiated. In 51 patients diagnosed as having abdominal sepsis, the latter was characterized as the endogenous intoxication syndrome in relation to the accumulation of low and medium molecular-weight substances (plasma and red blood cells in the body and their physiological elimination with urine. An original formula was used to calculate the integral marker – the endogenous intoxication index correlating with the routine severity rating scales APACHE II and SOFA and reflecting the severity of endotoxicosis. According to the values of the endogenous intoxication index and to the sum of scores by the APACHE II and SOFA scales, the patients were divided into 3 groups of the clinicopathogenetic types of endogenous intoxication. According to the type of endogenous intoxication, the authors proposed a differential approach to choosing the modes of efferent therapy for abdominal sepsis: high-volume plasmapheresis in the subcompensated type and prolonged venovenous hemofiltration, which improved the results of treatment and reduced mortality rates.

    A 51-year-old woman with relapsing–remitting multiple sclerosis (RRMS) and 3-year history of natalizumab use developed expressive aphasia. A brain magnetic resonance image (MRI) showed left frontotemporal and right parietal lesion with mild contrast enhancement and cerebrospinal fluid (CSF) was positive for John Cunningham virus (JCV) by polymerase chain reaction (PCR). The patient received five cycles of plasmapheresis followed by intravenous immunoglobulin. Despite this intervention, her speech deteriorated and she developed right hemiparesis. Upon referral to our institution, CSF quantitative JCV PCR was notable for 834 copies/ml. The patient was given an initial dose of 50,000 units of interleukin-2 (IL-2) subcutaneously (SQ) followed by 1 million units IL-2 SQ daily. Due to concern for immune reconstitution inflammatory syndrome (IRIS), the patient also received intravenous methylprednisone weekly. The regimen was tolerated well by the patient with no severe adverse effects. Clinically, the patient showed some improvement, and became more responsive and regained right lower extremity antigravity strength. After 12 weeks of IL-2 therapy, JCV quantitative PCR was notable for 31 copies/ml and the patient was more responsive. Due to persistence of JCV, IL-2 therapy was changed to mefloquine. At follow up after 6 months, the patient showed no clinical deterioration. PMID:27134676

    Full Text Available To determine the patterns and outcomes of the pauci-immune vasculitis in the nephrology department at hospital La Conception in Marseille, we conducted a retrospective study including all patients with diagnosis of pauci-immune renal vasculitis between January 1, 2000 and December 31, 2007. Among 33 cases, 25 were diagnosed as Wegener granulomatosis (WG, seven as microscopic polyangitis (MPA and one as Churg-Strauss syndrome (SCS. The median age of the patients was 57.7 years and the sex-ratio (M/F was 1.6. The visceral mani-festations included kidneys (100% of patients, lungs (75%, ENT (52% of WG, and nervous system (57% of MPA. The mean serum creatinine at admission was 3.3 mg/dL. Renal biopsies revealed a pauci-immune crescentic gromerulonephritis in 96% of the cases. Two patients with WG received plasmapheresis and seven patients required emergency hemodialysis. Induction therapy comprised cyclophosphamide IV and corticosteroids, while maintenance therapy included azathioprine for the majority of patients. Eighty four percent of the patients experienced complete remission after induction therapy. During maintenance therapy relapses were more frequent among patients with MPA (28% compared to WG cases (12%. After 35 months of follow-up, eight patients ended on chronic hemodialysis, and five patients died. ANCA associated vasculitis are frequent in our patients. Long-term outcomes are relatively good despite a mortality rate of 15% and 25% of the patients entering dialysis after three years of follow-up.

    Antibody-mediated rejection (AMR), also known as B-cell-mediated or humoral rejection, is a significant complication after kidney transplantation that carries a poor prognosis. Although fewer than 10% of kidney transplant patients experience AMR, as many as 30% of these patients experience graft loss as a consequence. Although AMR is mediated by antibodies against an allograft and results in histologic changes in allograft vasculature that differ from cellular rejection, it has not been recognized as a separate disease process until recently. With an improved understanding about the importance of the development of antibodies against allografts as well as complement activation, significant advances have occurred in the treatment of AMR. The standard of care for AMR includes plasmapheresis and intravenous immunoglobulin that remove and neutralize antibodies, respectively. Agents targeting B cells (rituximab and alemtuzumab), plasma cells (bortezomib), and the complement system (eculizumab) have also been used successfully to treat AMR in kidney transplant recipients. However, the high cost of these medications, their use for unlabeled indications, and a lack of prospective studies evaluating their efficacy and safety limit the routine use of these agents in the treatment of AMR in kidney transplant recipients. © 2014 Pharmacotherapy Publications, Inc.

  11. Significance of iron reduction for the therapy of chronic hepatitis C

    2005-01-01

    Full Text Available Background. It has been established that many patients with chronic hepatitis C have elevated serum iron, feritin levels and iron deposits in the liver. Therefore, the liver damage due to hepatitis C virus may be aggravated with iron overload. In many studies higher levels of iron in the blood and the liver were connected with the decreased response to interferon-alfa therapy for chronic viral hepatitis C. Recent introduction of pegylated interferons plus ribavirin has improved the therapeutic response, so it is now possible to cure more than 50% of the patients. Case report. Three patients with chronic hepatitis C and iron overload were presented. Iron reduction therapy using phlebotomy or eritrocytapheresis with plasmapheresis was done at different times in regard to specific antiviral therapy or as a sole therapy. Conclusion. It has been shown that iron reduction, sole or combined with antiviral therapy, led to the deacreased aminotransferase serum activity and might have slow down the evolution of chronic hepatitis C viral infection.

    We utilise a clinical case to highlight why exclusion of voltage-gated potassium channel (VGKC)-complex autoantibody testing in serological evaluation of patients may delay or miss the diagnosis. A 68-year-old man presented with increasing involuntary movements consistent with faciobrachial dystonic seizures (FBDS). Initial evaluation demonstrated VGKC antibody seropositivity with leucine-rich glioma-inactivated 1 (LGI1) and contactin-associated protein-like 2 (CASPR2) seronegativity. Aggressive immunotherapy with methylprednisolone and plasmapheresis was started early in the course of his presentation. Following treatment with immunotherapy, the patient demonstrated clinical improvement. Repeat serum evaluation 4 months posthospitalisation remained seropositive for VGKC-complex antibodies, with development of LGI1 autoantibody seropositivity. VGKC-complex and LGI1 antibodies remained positive 12 months posthospitalisation. Our findings suggest that clinical symptoms can predate the detection of the antibody. We conclude that when suspicion for autoimmune encephalitis is high in the setting of VGKC autoantibody positivity, regardless of LGI1 or CASPR2 seropositivity, early immunotherapy and repeat testing should be considered. 2017 BMJ Publishing Group Ltd.

  13. Myasthenia gravis: an update for the clinician

    Sieb, J P

    2014-01-01

    This paper provides a thorough overview of the current advances in diagnosis and therapy of myasthenia gravis (MG). Nowadays the term ‘myasthenia gravis’ includes heterogeneous autoimmune diseases, with a postsynaptic defect of neuromuscular transmission as the common feature. Myasthenia gravis should be classified according to the antibody specificity [acetylcholine, muscle-specific receptor tyrosine kinase (MuSK), low-density lipoprotein receptor-related protein 4 (LRP4), seronegative], thymus histology (thymitis, thymoma, atrophy), age at onset (in children; aged less than or more than 50 years) and type of course (ocular or generalized). With optimal treatment, the prognosis is good in terms of daily functions, quality of life and survival. Symptomatic treatment with acetylcholine esterase inhibition is usually combined with immunosuppression. Azathioprine still remains the first choice for long-term immunosuppressive therapy. Alternative immunosuppressive options to azathioprine include cyclosporin, cyclophosphamide, methotrexate, mycophenolate mofetil and tacrolimus. Rituximab is a promising new drug for severe generalized MG. Emerging therapy options include belimumab, eculizumab and the granulocyte– macrophage colony-stimulating factor. One pilot study on etanercept has given disappointing results. For decades, thymectomy has been performed in younger adults to improve non-paraneoplastic MG. However, controlled prospective studies on the suspected benefit of this surgical procedure are still lacking. In acute exacerbations, including myasthenic crisis, intravenous immunoglobulin, plasmapheresis and immunoadsorption are similarly effective. PMID:24117026

    Myasthenia gravis (MG) is an autoimmmune disease in which autoantibodies to different antigens of the neuromuscular junction cause the typical weakness and fatigability. Treatment includes anticholinesterase drugs, immunosuppression, immunomodulation, and thymectomy. The autoimmune response is maintained under control by corticosteroids frequently associated with immunosuppressive drugs, with improvement in the majority of patients. In case of acute exacerbations with bulbar symptoms or repeated relapses, modulation of autoantibody activity by plasmapheresis or intravenous immunoglobulins provides rapid improvement. Recently, techniques removing only circulating immunoglobulins have been developed for the chronic management of treatment-resistant patients. The rationale for thymectomy relies on the central role of the thymus. Despite the lack of controlled studies, thymectomy is recommended as an option to improve the clinical outcome or promote complete remission. New videothoracoscopic techniques have been developed to offer the maximal surgical approach with the minimal invasiveness and hence patient tolerability. The use of biological drugs such as anti-CD20 antibodies is still limited but promising. Studies performed in the animal model of MG demonstrated that several more selective or antigen-specific approaches, ranging from mucosal tolerization to inhibition of complement activity or cellular therapy, might be feasible. Investigation of the transfer of these therapeutic approaches to the human disease will be the challenge for the future. PMID:21552317

    Purpose Pembrolizumab, a monoclonal antibody which inhibits the programmed cell death 1 receptor, has been shown to efficaciously enhance pre-existing immune responses to malignancies. However, safety concerns must also be considered as pembrolizumab use has been associated with several life-threatening immune-related adverse events (irAEs). We report a fatal case of pembrolizumab-induced myasthenia gravis in a patient with no prior myasthenia gravis history. Case report A 63-year-old male presented with right eyelid drooping, puffiness, blurred vision, and shortness of breath two weeks after an initial infusion of pembrolizumab. He was subsequently diagnosed with new onset acetylcholine-receptor positive myasthenia gravis. Despite aggressive treatment with corticosteroids, pyridostigmine, intravenous immunoglobulin, and plasmapheresis, the patient clinically deteriorated and ultimately expired from acute respiratory failure after a 12-day hospitalization. Discussion Current package labeling for pembrolizumab warns against various irAEs associated with its use including pneumonitis, colitis, and endocrinopathies. To date, only one case of new onset myasthenia gravis and two case reports of myasthenia gravis exacerbation have been identified. This case further highlights the mortality risk associated with development of irAEs. Conclusion While rare, evidence for the development of MG associated with pembrolizumab is growing. Prompt recognition of symptoms and discontinuation of pembrolizumab is necessary to help improve prognosis.

    Susac’s syndrome (SS) is a triad of encephalopathy, branch retinal artery occlusion (BRAO), and sensorineural hearing loss as a result of microvascular occlusions of the brain, retina, and inner ear. It is also a disorder of autoimmune endotheliopathy. SS usually affects young women between the age of 20 and 40 years. SS can be misdiagnosed as multiple sclerosis (MS) or acute disseminated encephalomyelitis (ADEM) because of similar findings. A 15-year-old girl presented in June 2015 with vomiting and severe headache. Cerebral magnetic resonance imaging revealed multiple lesions in the corpus callosum. Cerebrospinal fluid findings gave normal results. The initial diagnosis was MS and steroid (1000 mg/day) was given. She started to describe hallucinations and became paraplegic. She then underwent plasmapheresis five times without response. Her electroencephalogram was diffusely slow with 2–3 Hz delta rhythm at the frontal regions. Audiological examination showed that she had sensorineural hearing loss in her left ear. Ophthalmologic evaluation revealed BRAO in both eyes. On the basis of these findings, she was diagnosed with SS and treated with intravenous immunoglobulin (IVIG) and aspirin. After monthly treatment with IVIG for 6 months, the patient has almost fully recovered. SS should be kept in mind in the differential diagnosis of MS and ADEM. PMID:29675082

    Organ donors are sometimes found "unsuitable" due to the presence of donor-specific anti-HLA antibodies in the recipient. In recent years, improved desensitization protocols have successfully helped to overcome HLA incompatibility hurdle. We present three cases where optimum desensitization was achieved in patients with the donor-specific anti-HLA antibody (DSA) leading to successful renal transplantation. All patient-donor pair underwent HLA typing, complement dependent cytotoxicity crossmatch (CDC-XM), flow cytometry XM (FC-XM), and panel reactive antibody. If any of the three tests was positive, single antigen bead assay was performed to determine the specificity of the anti-HLA antibody (s). Patients with DSA were offered organ-swap or anti-HLA antibody desensitization followed by transplantation. Desensitization protocol consisted of single dose rituximab and cascade plasmapheresis (CP) along with standard triple immunosuppression. The target DSA mean fluorescence index (MFI) was HLA DSA, who did not find a suitable match in organ swap program, consented to anti-HLA antibody desensitization, followed by transplantation. Mean pre-desensitization antibody MFI was 1740 (1422-2280). Mean number of CP required to achieve the target MFI was 2.3 (2-3). All the three patients are on regular follow-up and have normal renal function test at a mean follow-up of 8 months. This report underlines successful application of desensitization protocol leading to successful HLA-antibody incompatible renal transplants and their continued normal renal functions.

    2011-01-01

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is an uncommon life-threatening disease characterized by microangiopathic hemolytic anemia and thrombocytopenia, commonly associated with infections, malignancy, drugs, and autoimmune diseases. We report a case of 19-year-old previously healthy female that presents with anemia and thrombocytopenia diagnosed with thrombotic thrombocytopenic purpura that was treated successfully with plasmapheresis and corticosteroids. Laboratory findings also revealed antinuclear antibodies and antibodies to double-stranded DNA. Two weeks after presentation developed inflammatory arthritis, fulfilling diagnostic criteria for systemic lupus erythematosus (SLE. Prompt diagnosis and treatment with plasma exchange and corticosteroids should be instituted as soon as the diagnosis of TTP is suspected, even if other diagnoses, including lupus, are possible. When present, the coexistence of these two etiologies can have a higher mortality than either disease alone. An underlying diagnosis of SLE should be considered in all patients presenting TTP and the study of this association may provide a better understanding of their immune-mediated pathophysiology.

    To present a case of Graves' disease complicated by methimazole induced agranulocytosis treated with therapeutic plasma exchange (TPE) and review of the literature. A 21-year-old patient with a history of Graves' disease presented to the endocrine clinic. His history was significant for heat intolerance, weight loss, and tremors. Upon examination he had tachycardia, smooth goiter, thyroid bruit, and hyperactive reflexes. He was started on methimazole and metoprolol and thyroidectomy was to be done once his thyroid function tests normalized. On follow-up, the patient symptoms persisted. Complete blood count done showed a white blood cell count of 2100 (4000-11,000 cells/cu mm) with a neutrophil count of 400 cells/cu mm, consistent with neutropenia. He was admitted to the hospital and underwent 3 cycles of TPE and was also given filgrastim. He improved clinically and his thyroxine (T4) levels also came down. Thyroidectomy was done. He was discharged on levothyroxine for postsurgical hypothyroidism. Plasmapheresis may be useful in the treatment of hyperthyroidism. It works by removing protein bound hormones and also possibly inflammatory cytokines. Further studies are needed to clarify the role of various modalities of TPE in the treatment of hyperthyroidism.

    Fibrinogen is substantially reduced by most plasmapheresis modalities but retained in selective plasma exchange using Evacure EC-4A10 (EC-4A). Although EC-4A's fibrinogen sieving coefficient is 0, a session of selective plasma exchange reduced fibrinogen by approximately 19%. Here, we investigated sieving coefficient in five patients. When the mean processed plasma volume was 1.15 × plasma volume, the mean reduction of fibrinogen during selective plasma exchange was approximately 15%. Fibrinogen sieving coefficient was 0 when the processed plasma volume was 1.0 L, increasing to 0.07 when the processed plasma volume was 3.0 L, with a mean of 0.03 during selective plasma exchange. When fibrinogen sieving coefficient was 0, selective plasma exchange reduced fibrinogen by approximately 10%. Scanning electron microscopy images revealed internal fouling of EC-4A's hollow fiber membrane by substances such as fibrinogen fibrils. Thus, fibrinogen reduction by selective plasma exchange may be predominantly caused by membrane fouling rather than filtration. © 2017 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    Contactin-associated protein 2 (Caspr2) antibody is a neuronal surface antibody (NSAb) capable of causing disorders involving central and peripheral nervous systems (PNS). Thymoma can be found in patients with Caspr2 antibodies and is most frequently associated with PNS symptoms. Myasthenia gravis can be found in these patients, but Hashimoto thyroiditis (HT) has not been reported. A 76-year-old woman presented with sub-acute-onset changes in mental status. Further investigations revealed thymoma and HT. The presence of NSAb was tested by immunofluorescence on human embryonic kidney-293 cells. Treatment included corticosteroids, azathioprine, thyroxine, plasmapheresis, and thymectomy. Caspr2 antibody was positive in serum but absent in CSF. Brain magnetic resonance imaging (MRI) showed diffuse cortical atrophy, but did not change significantly after treatments. Brain positron emission tomography (PET) revealed diffuse hypometabolism over the cerebral cortex. The patient's mental status only partially improved. In Caspr2 antibody-associated syndromes, thymoma can occur in patients presenting only with LE, and HT can be an accompanying disease. Brain MRI and PET may not show specific lesions in limbic area. Patients with Caspr2 antibodies and thymoma may not have good prognosis. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Adult living donor liver transplantations (ALDLTs across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR. Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety.

    Full Text Available Antibody-mediated rejection (AMR is a major cause of late kidney transplant failure. It is important to have an understanding of human-leukocyte antigen (HLA typing including well-designed studies to determine anti-MHC-class-I-related chain A (MICA and antibody rejection pathogenesis. This can allow for more specific diagnosis and treatment which may improve long-term graft function. HLA-specific antibody detection prior to transplantation allows one to help determine the risk for AMR while detection of DSA along with a biopsy confirms it. It is now appreciated that biopsy for AMR does not have to include diffuse C4d, but does require a closer look at peritubular capillary microvasculature. Although plasmapheresis (PP is effective in removing alloantibodies (DSAs from the circulation, rebound synthesis of alloantibodies can occur. Splenectomy is used in desensitization protocols for ABO incompatible transplants as well as being found to treat AMR refractory to conventional treatment. Also used are agents targeted for plasma cells, B cells, and the complement cascade which are bortezomib rituximab and eculizumab, respectively.

    Several studies have suggested that a positive lymphocyte cross-matching (XM) is associated with low graft survival rates and a high prevalence of acute rejection after adult living donor liver transplantations (ALDLTs) using a small-for-size graft. However, there is still no consensus on preoperative desensitization. We adopted the desensitization protocol from ABO-incompatible LDLT. We performed desensitization for the selected patients according to the degree of T lymphocyte cross-match titer, model for end-stage liver disease (MELD) score, and graft liver volume. We retrospectively evaluated 230 consecutive ALDLT recipients for 5 yr. Eleven recipients (4.8%) showed a positive XM. Among them, five patients with the high titer (> 1:16) by antihuman globulin-augmented method (T-AHG) and one with a low titer but a high MELD score of 36 were selected for desensitization: rituximab injection and plasmapheresis before the transplantation. There were no major side effects of desensitization. Four of the patients showed successful depletion of the T-AHG titer. There was no mortality and hyperacute rejection in lymphocyte XM-positive patients, showing no significant difference in survival outcome between two groups (P=1.000). In conclusion, this desensitization protocol for the selected recipients considering the degree of T lymphocyte cross-match titer, MELD score, and graft liver volume is feasible and safe.

    The shortage of deceased donors led to an increase of living donor kidney (LDK) transplantations performed in the presence of donor-specific antibodies (DSA) or ABO incompatibility (ABOi) using various desensitization protocols. We herein analyzed 26 ABOi and 8 Luminex positive DSA patients who were successfully desensitized by anti-CD20, antigen-specific immunoadsorption and/or plasmapheresis to receive an LDK transplant. Twenty LDK recipients with non-donor-specific HLA-antibodies (low risk) and 32 without anti-HLA antibodies (no risk) served as control groups. 1-year graft survival rate and renal function was similar in all 4 groups (creatinine: 1.63 ± 0.5 vs 1.78 ± 0.6 vs 1.64 ± 0.5 vs 1.6 ± 0.3 mg/dl in ABOi, DSA, low risk and no risk group). The incidence of acute T-cell mediated rejections did not differ between the 4 groups (15% vs 12, 5% vs 15% vs 22% in ABOi, DSA, low risk and no risk), while antibody-mediated rejections were only found in the DSA (25%) and ABOi (7.5%) groups. Incidence of BK nephropathy (BKVN) was significantly more frequent after desensitization as compared to controls (5/34 vs 0/52, p = 0.03). We demonstrate favorable short-term allograft outcome in LDK transplant recipients after desensitization. However, the desensitization was associated with an increased risk of BKVN.

    Intravenous immunoglobulin (IVIG) and/or plasmapheresis (PP) are effective in preventing antibody-mediated rejection (AMR) of kidney allografts, but AMR is still a problem. This study reports our experience in living donor renal transplantation in highly sensitized patients. Ten patients with positive crossmatch tests or high levels of panel-reactive antibody (PRA) were included. Eight patients were desensitized with pretransplant PP and low dose IVIG, and two were additionally treated with rituximab. Allograft function, number of acute rejection (AR) episodes, protocol biopsy findings, and the presence of donor-specific antibody (DSA) were evaluated. With PP/IVIG, six out of eight patients showed good graft function without AR episodes. Protocol biopsies revealed no evidence of tissue injury or C4d deposits. Of two patients with AR, one was successfully treated with PP/IVIG, but the other lost graft function due to de novo production of DSA. Thereafter, rituximab was added to PP/IVIG in two cases. Rituximab gradually decreased PRA levels and the percentage of peripheral CD20+ cells. DSA was undetectable and protocol biopsy showed no C4d deposits. The graft function was stable and there were no AR episodes. Conclusively, desensitization using PP/IVIG with or without rituximab increases the likelihood of successful living donor renal transplantation in sensitized recipients. PMID:19194545

    As HLAs antibody detection technology has evolved, there is now detailed HLA antibody information available on prospective transplant recipients. Determining single antigen antibody specificity allows for a calculated panel reactive antibodies (cPRA) value, providing an estimate of the effective donor pool. For broadly sensitized lung transplant candidates (cPRA ≥ 80%), our center adopted a pretransplant multimodal desensitization protocol in an effort to decrease the cPRA and expand the donor pool. This desensitization protocol included plasmapheresis, solumedrol, bortezomib and rituximab given in combination over 19 days followed by intravenous immunoglobulin. Eight of 18 candidates completed therapy with the primary reasons for early discontinuation being transplant (by avoiding unacceptable antigens) or thrombocytopenia. In a mixed-model analysis, there were no significant changes in PRA or cPRA changes over time with the protocol. A sub-analysis of the median fluorescence intensity (MFI) change indicated a small decline that was significant in antibodies with MFI 5000–10 000. Nine of 18 candidates subsequently had a transplant. Posttransplant survival in these nine recipients was comparable to other pretransplant-sensitized recipients who did not receive therapy. In summary, an aggressive multi-modal desensitization protocol does not significantly reduce pretransplant HLA antibodies in a broadly sensitized lung transplant candidate cohort. PMID:24666831

    Diffuse alveolar hemorrhage (DAH) is a rare but potentially catastrophic manifestation with a high mortality. Among rheumatologic diseases, it occurs most frequently in patients with systemic lupus erythematosus (SLE) and systemic vasculitis. Despite new diagnostic tools and therapies, it remains a diagnostic and therapeutic challenge. The aim of this work was to characterize the SLE patients with an episode of alveolar hemorrhage followed in our Clinical Immunology Unit (CIU). A retrospective chart review was carried out for all patients with SLE followed in CIU between 1984 and the end of 2013. We reviewed the following data: demographic characteristics, clinical and laboratory data, radiologic investigations, histologic studies, treatment, and outcome. We identified 10 episodes of DAH, corresponding to seven patients, all female. These represent 1.6% of SLE patients followed in our Unit. The age at DAH attack was 42.75 ± 18.9 years. The average time between diagnosis of SLE and the onset of DAH was 7.1 years. Three patients had the diagnosis of SLE and the DAH attack at the same time. Disease activity according to SLEDAI was high, ranging from 15 to 41. All patients were treated with methylprednisolone, 37.5% cyclophosphamide and 28.6% plasmapheresis. The overall mortality rate was 28.6%. © The Author(s) 2015.

    Full Text Available This work deals with the special features of formation of individual clinical phenotype with an evident humoral sensitizing in patients with arterial hypotension in structure of neurologic symptom complexes of organic lesion of the central nervous system in accordance with the features of disorders of immune resistance and changes of the hormonal background.Materials and methods. There was carried out an examination of 201 patients: 89 with vegetative dysfunction, 50 in remote period of the closed craniocerebral trauma and 64 with cerebral arachnoiditis on the background of the chronic nidi of infection.45 examined persons with physiological arterial hypotension formed a control group. There were carried out clinical and neurological examinations, monitoring of arterial pressure, definition of the state of the primary, secondary immunity and hormonal background.Results. The main pathogenetic mechanisms in individual clinical phenotype with an evident humoral sensitizing that were formed on the background of the chronic infection are more connected with the humoral link of immunity (the high concentration of circulating immune complexes of the small values of molecular weight and peptides of the mean molecular weight, the growth of IgM content and form autoimmune disorders. This category can be related to the patients with irreversible functional states that complicates prescription of therapeutic measures.Conclusions. For patients with an evident humoral sensitizing it is reasonable to use desensitizing preparations, enterosorbents, plasmapheresis in the complex treatment. At persistent viral infection the use of specific antiviral immunoglobulins of IgG is recommended

  13. Non-pharmacological strategies for blood conservation in cardiac surgery.

    Of all surgical specialties, cardiac operations are most often associated with coagulopathy, blood loss, and the need for transfusions. This not only represents a major burden on blood procurement and banking organizations at all levels, but also constitutes a risk for each patient receiving allogeneic blood products. This paper reviews current non-pharmacological strategies aimed at decreasing blood use in patients undergoing cardiac surgery. The literature pertaining to each blood conservation strategy was searched, reviewed, and appraised. Meta- analyses were also consulted and their results complemented with subsequent reports when available. Preoperative autologous donation programs are effective in decreasing allogeneic transfusions, but are costly and applicable to elective patients only. Off-pump revascularization strategies also appear to decrease transfusion requirements in suitable patients. The effectiveness of acute normovolemic hemodilution, retrograde autologous priming, small volume cardiopulmonary bypass circuits, platelet-rich plasmapheresis, alternative heparin strategies, and postoperative cell salvage are more difficult to appraise as a high proportion of available studies suffer from lack of transfusion guidelines or the absence of blinding. Biological glues, surgical adhesives, and postoperative increases in positive end-expiratory pressure (PEEP) have no demonstrated efficacy. The applicability or effectiveness of many of these modalities remains controversial and more studies are needed before they may be employed routinely in cardiac surgical patients. The judicious use of rational transfusion guidelines may still be the simplest and most cost-effective means of blood conservation today.

    A 55-year-old patient with multiple myeloma (IgG-λ) diagnosed in November 1988 was admitted because of bone pain throughout the body. After plasmapheresis and several courses of chemotherapy, a massive tumor of the left thoracic wall involving the rib appeared. Radiotherapy was performed to ameliorate the severe chest pain, after which myelomatous pleural effusion appeared on the left side. The serum, urine and pleural effusion revealed increased activity of amylase of the salivary type. Amylase activity was also detected in the supernatant of myeloma cells cultured from pleural effusion. We reviewed 12 cases of ectopic amylase-producing multiple myeloma. All the cases except one have been reported from Japan, and hyperamylasemia in these cases was detected at diagnosis or during course of the illness. Moreover, cytogenetic analysis of myeloma cells of previous reports revealed structural abnormalities including chromosome 1, near the amylase gene locus. This case also showed t (1; 10) (q21?; q26) by examination of 8 metaphase derived from bone marrow. These observations suggested that ectopic amylase production was induced by irradiation to the plasmacytoma of thoracic wall. (author)

    outcome and prognosis will be enhanced by performing a more extensive resection of the gland and of the anterior mediastinum tissue. OBJECTIVE: To retrospectively evaluate response of MG patients to extended thymectomy. METHOD: From August 1992 to January 2003, forty-six MG patients were submitted to preoperative plasmapheresis and extended thymectomy. According to the time elapsed since onset of symptom they were divided into three groups; 25 months. RESULTS: There were 31 female and 15 male patients, mean age 30 years and average evolution time 26.3 months. Outpatient post-operative follow-up was on the average of 26.6 months. Level of response was good, 50% had full remission and a further 39% had good response. There was one death. The most common histopathology finding was thymic hyperplasia. Only 3 patients (6.5% had benign thymomas; 5 (10.8% had extra glandular thymic tissue: 2 in the perithymic fat and 3 in the pericardiac fat adjacent to the left phrenic nerve and aortal-pulmonary window. CONCLUSION: Treatment of MG by extended thymectomy is safe and efficient with high levels of complete remission. Extra glandular thymic tissue was found in some patients. As soon as diagnosis is completed, thymectomy is indicated together with plasmapheresis and medication, independent of age, onset of symptoms, and thymus pathology.

    Waldenstrom's macroglobulinaemia (WM) is an uncommon B-cell lymphoproliferative disorder characterized by bone marrow infiltration and production of monoclonal immunoglobulin. Uncertainty remains if alkylating agents, such as chlorambucil, melphalan or cyclophosphamide, are an effective form of management. To assess the effects and safety of the alkylating agents on Waldenstrom's macroglobulinaemia (WM). We searched the Cochrane Central Register of Controlled Trials (Issue 1, 2008), MEDLINE (1966 to 2008), EMBASE (1980 to 2008), the Chinese Biomedical Base (1982 to 2008) and reference lists of articles.We also handsearched relevant conference proceedings from 1990 to 2008. Randomised controlled trials (RCTs) comparing alkylating agents given concomitantly with radiotherapy, splenectomy, plasmapheresis, stem-cell transplantation in patients with a confirmed diagnosis of WM. Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. We collected adverse effects information from the trials. One trial involving 92 participants with pretreated/relapsed WM compared the effect of fludarabine versus the combination of cyclophosphamide (the alkylating agent), doxorubicin and prednisone (CAP). Compared to CAP, the Hazard ratio (HR) for deaths of treatment with fludarabine was estimated to be 1.04, with a standard error of 0.30 (95% CI 0.58 to 1.48) and it indicated that the mean difference of median survival time was -4.00 months, and 16.00 months for response duration. The relative risks (RR) of response rate was 2.80 (95% CI 1.10 to 7.12). There were no statistically difference in overall survival rate and median survival months, while on the basis of response rate and response duration, fludarabine seemed to be superior to CAP for pretreated/relapsed patients with macroglobulinaemia. Although alkylating agents have been used for decades they have never actually been tested in a proper randomised trial. This

    Cryofibrinogenemia is frequently associated with cryoglobulinemia. The aim of this study was to determine the characteristics associated with the presence of cryofibrinogenemia in patients with cryoglobulinemic vasculitis. This was a single-center retrospective study that included patients with cryoglobulinemic vasculitis who were tested for cryofibrinogen at a tertiary referral center between January 1, 2011 and December 31, 2012. Twenty-nine patients fulfilled the CryoVas (cryoglobulinemic vasculitis) Survey criteria for cryoglobulinemic vasculitis. Eighteen patients had a detectable cryofibrinogen (CF-positive) and 11 had no detectable cryofibrinogen (CF-negative). Median cryoglobulin levels were 89 ± 129 mg/L in the CF-positive group and 68 ± 82 mg/L in the CF-negative group (P = .32). Median cryofibrinogen level was 70 ± 174 mg/L. Clinical manifestations were similar in both groups. Cancers and hematological disorders were more frequent among CF-positive patients (39% vs 0%, P = .026). Levels of alpha-1 and alpha-2 globulinemia were higher in the CF-positive group. Cryofibrinogenemia ≥ 100 mg/L was associated with cryoglobulinemic vasculitis (odds ratio [OR] 2.86; 95% confidence interval [CI], 1.06-7.73) in cryoglobulinemic patients. Presence of cryofibrinogenemia was associated with use of corticosteroids, immunosuppressants, or plasmapheresis in cryoglobulinemic vasculitis patients (OR 22.7; 95% CI, 2.02-256.44). Our results strongly suggest that presence of cryofibrinogenemia is associated with a more severe phenotype among patients with cryoglobulinemic vasculitis. Copyright © 2015 Elsevier Inc.

    Cryoglobulinemic vasculitis (CryoVas) is a small-vessel vasculitis involving mainly the skin, the joints, the peripheral nervous system, and the kidneys. Type I CryoVas is single monoclonal immunoglobulins related to an underlying B-cell lymphoproliferative disorder. Type II and III cryoglobulins, often referred to as mixed cryoglobulinemia, consist of polyclonal immunoglobulin (Ig)G with or without monoclonal IgM with rheumatoid factor activity. Hepatitis C virus (HCV) infection represents the main cause of mixed CryoVas. The 10-year survival rates are 63%, 65%, and 87% in HCV-positive mixed CryoVas, HCV-negative mixed CryoVas, and type I CryoVas patients, respectively. In HCV-positive patients, baseline poor prognostic factors include the presence of severe liver fibrosis, and central nervous system, kidney, and heart involvement. Treatment with antivirals is associated with a good prognosis, whereas use of immunosuppressants (including corticosteroids) is associated with a poor outcome. In HCV-negative patients, pulmonary and gastrointestinal involvement, renal insufficiency, and age > 65 years are independently associated with death. Increased risk of lymphoma also should be underlined. Treatment of type I CryoVas is that of the hemopathy; specific treatment also includes plasma exchange, corticosteroids, rituximab, and ilomedine. In HCV-CryoVas with mild-to-moderate disease, an optimal antiviral treatment should be given. For HCV-CryoVas with severe vasculitis (ie, worsening of renal function, mononeuritis multiplex, extensive skin disease, intestinal ischemia…) control of disease with rituximab, with or without plasmapheresis, is required before initiation of antiviral therapy. Other immunosuppressants should be given only in case of refractory forms of CryoVas, frequently associated with underlying B-cell lymphoma. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a rare blood disorder with an estimated incidence of 4–5 cases per million people per year. It is characterized by small-vessel platelet-rich thrombi that cause thrombocytopenia, microangiopathic hemolytic anemia and organ damage. There are reports in literature that TTP and acute pancreatitis are associated, indicating each can be the cause of the other. However, acute pancreatitis triggering TTP is very rare. A 71 years old female presented with abdominal pain of 3 days, followed by dark urine. She had icteric sclera, petechial rash and mild epigastric tenderness. Lab findings were significant for hemolytic anemia, thrombocytopenia and elevated lipase. CT of abdomen showed evidence of pancreatitis and cholelithiasis. After admission, patient developed symptoms of stroke. Further investigation showed elevated lactate dehydrogenase and normal coagulation studied with peripheral blood smear showed 5–6 schistocytes/high power field. Disintegrin and metalloproteinase with thrombospondin motifs-13 (ADAMTS13 activity showed less than 3% with high ADAMTS13 inhibitor 2.2. Patient required 6–7 weeks of daily plasmapheresis until she showed complete response. Our patient presented with clinical features of pancreatitis prior to having dark urine and petechial rash. Therefore, we strongly believe that our patient had pancreatitis which was followed by TTP. Patient's ADMTS13 activity was 6% after 10 plasma exchanges, signifying refractory TTP and higher risk for morbidity and mortality. There are limited data and consensus on the management of refractory TTP. TTP and acute pancreatitis are associated. However, refractory TTP following acute pancreatitis is rarely mentioned in the literature. We would like to emphasize the importance of having higher clinical suspicion of the association of both disease entities.

    Anti-glomerular basement membrane (GBM) disease is a severe inflammatory renal disorder due to pathogenic autoantibodies directed mainly against the α3 chain of type IV collagen. In ~1/4 of patients with anti-GBM disease, antineutrophil cytoplasmic antibodies (ANCA) predominantly with myeloperoxidase (MPO) specificity can be detected. Although the inciting stimuli leading to the development of an immune response against the type IV collagen and neutrophils are unknown, evidence indicates that both genetic and environmental factors play a role. Of note, molecular mimicry between self-antigens and nonself-antigens such as antigenic determinants of microorganisms has been implicated in the pathogenesis of anti-GBM disease and ANCA-associated vasculitis. A mosquito-borne viral illness highly prevalent in the tropics and subtropics, dengue can be complicated by acute renal failure, proteinuria, hematuria and glomerulonephritis. We present a 66-year-old woman who was diagnosed with dengue infection and rapidly progressive glomerulonephritis during an outbreak of dengue in Honduras in the summer of 2013. Renal biopsy revealed severe crescentic glomerulonephritis. Immunofluorescence examination demonstrated strong linear IgG deposition along glomerular capillary walls. Serologic tests demonstrated antibodies against GBM, MPO and platelet glycoproteins. The patient was diagnosed with anti-GBM disease associated with p-ANCA with MPO specificity. Despite heavy immunosuppression and plasmapheresis, IgG titers against dengue virus continued to rise confirming the diagnosis of acute dengue infection. We present the first reported case of anti-GBM disease associated with p-ANCA with MPO specificity during dengue infection. This report calls for a heightened awareness of autoimmunity leading to crescentic glomerulonephritis in patients with dengue infection.

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two of the most severe dermatologic conditions occurring in the inpatient setting. There is a lack of consensus regarding appropriate management of SJS and TEN. The scientific literature pertaining to SJS and TEN (subsequently referred to as SJS/TEN) is summarized and assessed. In addition, an interventional approach for the clinician is provided. PubMed was searched with the key words: corticosteroids, cyclosporine, etanercept, intravenous immunoglobulin, Stevens-Johnson syndrome, and toxic epidermal necrolysis. The papers generated by the search, and their references, were reviewed. Supportive care is the most universally accepted intervention for SJS/TEN. Specific guidelines differ from the care required for patients with thermal burns. Adjuvant therapies are utilized in most severe cases, but the data are thus far underwhelming and underpowered. Using systemic corticosteroids as sole therapy is not supported. A consensus regarding combined corticosteroids and intravenous immunoglobulin (IVIG) has not been reached. Data regarding IVIG, currently the standard of care for most referral centers, is conflicting. Newer studies regarding cyclosporine and tumor necrosis factor inhibitors are promising, but not powered to provide definitive evidence of efficacy. Data regarding plasmapheresis is equivocal. Thalidomide increases mortality. Clinicians who manage SJS/TEN should seek to employ interventions with the greatest impact on their patients' condition. While supportive care measures may seem an obvious aspect of SJS/TEN patient care, providers should understand that these interventions are imperative and that they differ from the care recommended for other critically ill or burn patients. While adjuvant therapies are frequently discussed and debated for hospitalized patients with SJS/TEN, a standardized management approach is not yet clear based on the current data. Therefore, until further data

    The Robert Koch Institute collects and evaluates nationwide data on the incidence and prevalence of transfusion-relevant infections among blood and plasma donors in Germany. Since 2006 data not only on the number of donations tested but also on the number of the respective donors have become available. The demographic profile and donation frequencies of German whole blood, plasma and platelet donors in 2010 and the percentages among the general population are described and compared to data from 2006. Although the general population eligible to donate blood is on the decline since 2003, with a loss of 2% between 2006 and 2010, this has not led to a decrease in the number of blood donors and donations. Instead, the number of new and repeat whole blood donors increased by 8% and 7%, respectively. At the same time, the number of new plasma donors grew by 23%, that of repeat plasma donors by 41%. In 2010 more than 4.3% of the population aged 18-68 years was active as repeat whole blood donors; 0.4% repeatedly donated plasma or platelets. Since 2006 the percentage of donors among the general population increased significantly, especially among the youngest age group (18-24 years). Donation frequency varied depending on donor age and sex, with an average of 1.9 per year for whole blood donations, 12.5 for plasmapheresis and 5.0 for plateletpheresis. While the donation frequency for whole blood remained unchanged since 2006, the frequency of apheresis donations increased, especially among older donors. By recruiting more new donors and retaining and reactivating existing ones more effectively, the number of whole blood and apheresis donations was augmented.

    According to Article 22 of the Transfusion Act, the Robert Koch Institute collects and evaluates nationwide data on the prevalence and incidence of transfusion-relevant infections among blood and plasma donors in Germany. Due to revision of the Transfusion Act in 2005 not only the number of donations but also the number of donors has become available for analysis. Here we give a detailed account on the demographic profile and donation frequencies of German whole blood, plasma and platelet donors in 2006. Overall, 4 % of the German population eligible to donate were active as repeat whole blood donors in 2006; 0.3 % repeatedly donated plasma or platelets. Irrespective of the type of donation, the percentage of donors among the general population was highest among the youngest age group (18 to 24 years). While the age distribution of whole blood repeat donors roughly resembled that of the general population, with the greatest number among those aged 35 to 44, younger age groups were overrepresented among repeat plasma donors. Donation frequency varied depending on donor age and sex, with an average of 1.9 per year for whole blood donations, 11.9 for plasmapheresis and 4.0 for plateletpheresis. With the exception of the latter, men donated more frequently than women. For both sexes, donation frequency increased with age. Detailed knowledge of the demographic profile and changes in the composition of donor populations are essential for planning adequate blood supply. The data presented may serve as reference for assessing the consequences of measures that affect the number of donors and/or donations (for example changing deferral criteria) in Germany.

    Diabetes mellitus complicated with insulin antibodies is rare in clinical practice but usually difficult to control. A high amount of insulin antibodies, especially with low affinity and high binding capacity, leads to unstable glycemic control characterized by hyperglycemia unresponsive to large volume of insulin and unanticipated hypoglycemia. There are several treatment options, such as changing insulin preparation, immunosupression with glucocorticoids, and plasmapheresis, most of which are of limited efficacy. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a novel class of drug which decrease renal glucose reabsorption and lowers plasma glucose level independent of insulin action. We report here a case with diabetes complicated with insulin antibodies who was effectively controlled by an SGLT2 inhibitor. A 47-year-old man with type 2 diabetes treated with insulin had very poor glycemic control characterized by postprandial hyperglycemia unresponsive to insulin therapy and repetitive hypoglycemia due to insulin antibodies. Treatment with ipragliflozin, an SGLT2 inhibitor, improved HbA1c from 8.4% to 6.0% and glycated albumin from 29.4% to 17.9%. Continuous glucose monitoring revealed improvement of glycemic profile (average glucose level from 212 mg/dL to 99 mg/dL and glycemic standard deviation from 92 mg/dL to 14 mg/dL) with disappearance of hypoglycemic events. This treatment further ameliorated the characteristics of insulin antibodies and resulted in reduced insulin requirement. SGLT2 inhibitors may offer an effective treatment option for managing the poor glycemic control in diabetes complicated with insulin antibodies.

    The advent of effective immune treatment has meant that myasthenia gravis (MG) is most often not lethal. However, many MG patients still find it difficult to maintain daily activities due to chronic residual fatigability and long-term side effects of medication, since full remission without immune treatment is not common. Our analysis demonstrated that disease severity, dose of oral corticosteroids, and depressive state are the major independent factors negatively associated with self-reported QOL (MG-QOL15-J score). It is noteworthy that oral corticosteroid, the first-line agent for MG, is negatively associated with patients' QOL. When the analysis took into account MGFA postintervention status and dose of oral prednisolne (PSL), the MG-QOL15-J score of MM status patients taking ≤ 5 mg PSL per day is identically low (i.e., just as good QOL) as that seen in CSR and is a target of treatment. In order to veer away from high-dose oral corticosteroids and to achieve early MM or better status with PSL ≤ 5 mg/day, we advocate the early aggressive treatment strategy that can achieve early improvement by performing an aggressive therapy using combined treatment with plasmapheresis and high-dose intravenous methylprednisolone and then maintain an improved clinical status using low-dose oral corticosteroids and calcineurin inhibitors (cyclosporine microemulsion and tacrolimus). The early stages of MG are susceptible to treatment with calcineurin inhibitors. When using cyclosporine microemulsion for MG, blood concentrations 2 h after administration (C2) correlate with clinical improvement and immediately before administration (C0) with side effects (increased serum creatinine and/or hypertension). Monitoring of C2 and C0 levels is useful to estimate efficacy and safety of the drug.

    Full Text Available Introduction & Objective: Since the elimination of poliomyelitis from Iran, Guillain–Barre Syndrome (GBS has been the leading cause of acute flaccid paralysis. There are a few studies concerning clinical and epidemiologic features of Guillain-Barré syndrome in our country, therefore we evaluated ten years clinical and epidemiologic features of GBS in Sina hospital, Hamadan, Iran.Materials & Methods: In a retrospective descriptive study, we reviewed 80 records of patients with GBS who were hospitalized in Sina Hospital (Hamadan, Iran during 1993-2003. Because of incomplete data we excluded 29 patients from the study. We evaluated clinical and epidemiologic features, risk factors, lab data and management protocols. Complete remission defined as complete improved patient four weeks after the GBS treatment and partial remission as the continuation of the symptom after that time. All the data extracted manually and analyzed with SPSS software.Results: From 51 patients, 36 (70.59% were men and 15 (29.41% women, with a proportion of 2.4 men to 1 woman. The age ranged from 3 to 85 years. The highest frequency was observed in patients aged 11 to 20 (35.28%. 13 patients were student, 11 were house keeper, 11 were farmer, 7 were worker. 29 patients (56.84% had risk factors like respiratory and gastrointestinal track infection, surgery and fever before the disease onset. Complete and partial remission occurred in 17 and 28 patients respectively and 5 patients did not improve. Management failure occurred in 3 (8.83%, 2 (22.23% and 5 (62.5% patients who underwent IVIG, plasmapheresis and corticosteroids respectively.Conclusion: Our data was not similar to other studies in term of male to female proportion, age distribution and management protocols, therefore geographical pattern of the disease should be concerned for better patients’ management.

    Humoral rejection is an important cause of early and late graft loss. The late variant is difficult to diagnose and treat. There is a close correlation between sclerosing nephropathy and anti-HLA antibodies. We analyzed 113 renal allograft recipients between August 2004 and April 2007. Acute humoral rejection was defined as acute graft dysfunction in presence of donor-specific antibodies (DSA) detected by flow panel reactive antibodies (PRA) and/or C4d positive pericapilary tubules (PTC) detected histopathologically by immunofluorescent or immunoperoxidase at less than 3 months postransplantation. Late humoral rejection was defined as dysfunction occurring after 3 months postransplantation with histopathologic glomerulopathy or vasculopathy and positive C4d PTC. We included all patients who were diagnosed with early or late graft dysfunction and underwent biopsy, all of which were examined for C4d. Four patients had acute humoral rejection treated with IVIG or plasmapheresis. The patient and graft survivals were 100% and serum creatinine averaged 1.7 mg/dL. Three recipients experienced late humoral rejection at 3 to 10 years posttransplantation All received high-dose IVIG; one also was treated with thymoglobulin. Immunosuppression was switched to tacrolimus, mycophenolate mofetil, and steroids. Only one patient recovered renal function; the others returned to dialysis. Among seven patients only one had an actual PRA (>20%) and three showed 10% to 20%. However, six had a positive historical PRA of 10% to 50%. In conclusion, Recognition of acute humoral rejection has contributed to graft rescue by controlling alloantibody production through new specific immunosuppressive therapies in contrast with the clinical response to acute therapy, treatment of a chronic entity has shown poor outcomes, probably because antibody mediated chronic graft damage is already present when the late diagnosis is established by biopsy.

    Pregnant women with triple antibody positive antiphospholipid syndrome (APS) who have had thrombosis or a history of early, severe pregnancy complications are generally considered at high risk of pregnancy loss. The objectives of this study were to investigate the efficacy and safety of a relatively new treatment protocol used in addition to conventional therapy in high-risk pregnant patients affected with primary APS. The study's two inclusion criteria were: (1) the presence of triple antiphospholipid positivity, (2) previous thrombosis and/or a history of one or more early, severe pregnancy complications. Eighteen pregnancies occurring between 2002 and 2015 in 14 APS patients, (mean age 34.8±3.6 SD) were monitored. All 14 (100%) patients had triple antiphospholipid positivity. In addition, six of them (42.8%) had a history of thrombosis, four (28.6%) had one or more previous early and severe pregnancy complications, and four (30.8%) met both clinical study criteria. The study protocol included weekly plasmapheresis or immunoadsorption and fortnightly 1g/kg intravenous immunoglobulins. Seventeen of the pregnancies (94.4%) produced live neonates, all born between the 26th and 37th weeks of gestation (mean 33.1±3.5 SD). One female (5.5%), born prematurely at 24 weeks, died of sepsis a week after birth. There were two cases (11.1%) of severe pregnancy complications. No treatment side effects were registered. Given the high live birth rate and the safety associated to it, the study protocol described here could be taken into consideration by medical teams treating high-risk APS pregnant patients.

    Effective recruitment and retention of male donors are vital for the ongoing provision of blood products. Compared with females, male donors are less likely to be medically deferred or experience vasovagal reactions and are typically preferred for plasmapheresis donation in voluntary non-remunerated settings. However, females outnumber males among donors aged under 40 years. This systematic review aimed to synthesize evidence and identify key motivators for blood donation among males to inform targeted recruitment/retention campaigns. Databases (e.g. EBSCOhost, Web of Science) were searched using terms (dona* OR dono*) AND (blood OR aphaeresis OR apheresis OR plasma* OR platelet* OR platlet*) in title AND (male OR gender OR sex OR female) AND (motivat* OR intention OR attitude OR behavi* OR predictor OR barrier OR deter*) NOT (organ OR sperm OR tissue OR autologous OR oocyte) in text. Two researchers independently systematically scanned quantitative, full-text, English language, peer-reviewed publications from 1990 to 2015 that examined males/females separately with outcomes of blood donation or self-reported intention. Two additional researchers resolved discrepancies. Among 28 identified articles, the most frequently cited motivators for male blood product donation were as follows: altruism; positive attitude towards incentives; health check(s); subjective norms. Altruism was less pronounced among males compared with females and was combined with 'warm glow' in novice males (impure altruism). Perceived health benefits and incentives (e.g. coffee mugs) were stronger motivators of males than females. Marketing campaigns for recruitment/retention of male donors should focus on identified motivators rather than take a 'one-size-fits-all' approach. © 2017 International Society of Blood Transfusion.

    Full Text Available Relapse in multiple sclerosis (MS is defined as a neurologic deficit associated with an acute inflammatory demyelinating event that lasts at least 24 hours in the absence of fever and infection. Myelinoclasis and axonal transection occur in relapses. Diagnosis, prognosis, treatment, and many other features of the disease are directly related to the relapses. MS starts as the relapsing-remitting (RRMS form in 85% of patients. A large number of relapses in the first years, polysymptomatic relapses, and pyramidal system, brain stem, and spinal cord involvement are signs of a poor outcome. The average frequency of relapses is approximately one per year during the first years of RRMS. The frequency of relapses increases during systemic infections, psychological stress, and in the postpartum first 3 months. Seventy-five percent of relapses are monosymptomatic. Pseudo-relapses and paroxysmal symptoms are distinguished from relapses by their sudden onset, sudden termination, and shorter duration. Contrast enhancement is valuable in imaging, but undetectable in most relapses. The regression in the first few weeks of relapses is explained by reduction of the edema, and by remyelination in the following months. Relapses and their features are also among the main determinants of treatment. High-dose methylprednisolone and early treatment with adrenocorticotropic hormone reduce post-relapse disability and shorten the duration of relapses. Plasmapheresis is a good option for patients who do not respond to steroid treatment. Identification of relapses by patients and physicians, distinguishing them from imitators, proper evaluation, treatment when necessary, and monitoring the results are of great importance for patients with MS. The educational levels of patients and physicians regarding these parameters should be increased. Well-designed studies that evaluate the long-term effect of relapse treatment on disability are needed.

    Antibody-mediated rejection (AMR) is an important factor affecting survival after renal transplantation. A highly selective proteasome inhibitor, bortezomib, clears activated plasma cells from the body and has important therapeutic effect on AMR. We investigated the effects of bortezomib on AMR in a patient after a second renal transplant. Biopsy confirmed the diagnosis of mixed cellular rejection and AMR. Bortezomib was administered on day 1 (1.3 mg/m(2)), day 4 (1.0 mg/m(2)), and day 8 (1.0 mg/m(2)). On the same days, 250 mg methylprednisolone was administered once, and cyclosporine dose (5 mg·kg(-1)·day(-1)) was reduced by 50%. Oral mycophenolate mofetil and steroid were withdrawn on day 1 of bortezomib treatment. Intermittent double-filtration plasmapheresis was also performed. We monitored parameters, including T lymphocyte subsets, CD139 and CD19 expression, panel reactive antibody (PRA), and serum creatinine concentration. At follow-up 6 months after bortezomib treatment, we observed: 1) serum creatinine stabilized at 130 μM from a peak level of 337 μM; 2) PRA decreased from a maximum of 66.7 to 0%; 3) blood plasma cell percentage rebounded after significantly decreasing following the first dose of bortezomib; 4) in renal allograft biopsy, immunohistochemical staining for C4d shifted from strongly positive to negative, and cellular rejection shifted from type IIA to borderline; and 5) adverse effects such as platelet suppression, hypotension, and grade 3 peripheral neuropathy emerged. Bortezomib effectively treated antibody-mediated renal transplantation rejection in this case study, but clinical trials with large sample sizes are still needed to explore clinical safety and tolerability.

    Neuropsychiatric systemic lupus erythematosus (NPSLE) is a generic definition referring to a series of neurological and psychiatric symptoms directly related to systemic lupus erythematosus (SLE). NPSLE includes heterogeneous and rare neuropsychiatric (NP) manifestations involving both the central and peripheral nervous system. Due to the lack of a gold standard, the attribution of NP symptoms to SLE represents a clinical challenge that obligates the strict exclusion of any other potential cause. In the acute setting, management of these patients does not differ from other non-SLE subjects presenting with the same NP manifestation. Afterwards, an individualized therapeutic strategy, depending on the presenting manifestation and severity of symptoms, must be started. Clinical trials in NPSLE are scarce and most of the data are extracted from case series and case reports. High-dose glucocorticoids and intravenous cyclophosphamide remain the cornerstone for patients with severe symptoms that are thought to reflect inflammation or an underlying autoimmune process. Rituximab, intravenous immunoglobulins, or plasmapheresis may be used if response is not achieved. When patients present with mild to moderate NP manifestations, or when maintenance therapy is warranted, azathioprine and mycophenolate may be considered. When symptoms are thought to reflect a thrombotic underlying process, anticoagulation and antiplatelet agents are the mainstay of therapy, especially if antiphospholipid antibodies or antiphospholipid syndrome are present. Recent trials on SLE using new biologicals, based on newly understood SLE mechanisms, have shown promising results. Based on what we currently know about its pathogenesis, it is tempting to speculate how these new therapies may affect the management of NPSLE patients. This article provides a comprehensive and critical review of the literature on the epidemiology, pathophysiology, diagnosis, and management of NPSLE. We describe the most

    2015-05-01

    Hypertriglyceridemia (HTG) is a common metabolic disorder in which the concentration of very low density lipoproteins (VLDL) and of chylomicrons (CMs) is elevated in the plasma. HTG may be caused by primary and/or secondary causes and affected subjects may express HTG when children or in adulthood. In children and adults a genetic cause may underlie HTG which can be expressed as CMs a severe clinical picture known as Familial Hyperchylomicronemia due to lipoprotein lipase (LPL) or apolipoprotein (apo) CII deficiencies. Genetically determined HTG includes Familial Dysbetalipoproteinemia due to deficiency of apolipoprotein EIII of VLDL and Familial HTG. However, recent data suggest that classical Fredrickson phenotypes describing clinically HTG, which were once considered to be distinct based on biochemical features, have a shared genetic set up. The HTG has been classified according to a recent international paper: mild HTG: 2-10 mmol/L (176-882 mg/dL); severe HTG: > 10 mmol/L (>882 mg/dL) associated to CMs remnants, or Intermediate Density lipoprotein (IDL) like particles, and/or CMs. The treatment includes limitation of dietary content of saturated fat and alcohol, fibrates and omega3 fatty acids. When TG are severely elevated and associated to CMs the risk of acute pancreatitis suggests the use of more drastic therapeutic option such as therapeutic plasma exchange. This paper summarizes the experience with conventional plasmapheresis (Plasma-Exchange, PEX) and different Lipoprotein Apheresis methods with respect to acutely lowering TG levels in patients with normal TG, with mild and severe HTG. Upcoming promising therapies are gene therapy, novel apolipoprotein CIII inhibitors and lomitapide. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Materials and Methods: The data of 40 patients with Guillain-Barré syndrome who had been admitted to the Department of Pediatrics at the Istanbul University Medical Faculty between 2005 and 2011 were collected. Mann-Whitney U, Kruskal-Wallis, chi-square, and Fisher′s exact tests were used for statistical analysis. Results: Mean patient age was 5.4 ± 3.0 years; 20 out of 40 patients (50% were female and 20 (50% were male. Preceding infection was detected in 32 cases (80%. Six patients had speech impairment. Out of eight patients with respiratory distress (20%, five required respiratory support (12.5% of which three of them had speech impairment as well. According to nerve conduction studies, 21 patients (52.5% had acute inflammatory demyelinating polyradiculoneuropathy, 14 (35% had acute motor axonal neuropathy, and five (12.5% had acute motor-sensory axonal neuropathy. Thirty-three patients (82.5% received intravenous immunglobulin, 3 (7.5% underwent plasmapheresis and 4 (10% received both. Time until recovery (P = 0.022 and time until aided (P = 0.036 and unaided (P = 0.027 walking were longer in patients with acute gastrointestinal infection than in those with upper respiratory tract infection (P < 0.05.

    To determine the diverse clinical features of optic neuropathy associated with primary Sjögren's syndrome in Korean patients. Five women with acute and/or chronic optic neuropathy who were diagnosed as primary Sjögren's syndrome were retrospectively evaluated. Primary Sjögren's syndrome was diagnosed by signs and symptoms of keratoconjunctivitis sicca, positive serum anti-Ro/SSA and/or anti-La/SSB antibodies, and/or minor salivary gland biopsy. All patients underwent a complete ophthalmologic examination. Among the five patients diagnosed as optic neuropathy related to primary Sjögren's syndrome, four patients had bilateral optic neuropathy and one patient was unilateral. The clinical course was chronic in three patients and one of them showed acute exacerbation and was finally diagnosed with neuromyelitis optica spectrum disorder. The other two patients presented as acute optic neuritis and one was diagnosed with neuromyelitis optica spectrum disorder. Sicca symptoms were present in four patients, but only two patients reported these symptoms before the onset of optic neuropathy. Patients showed minimal response to systemic corticosteroids or steroid dependence, requiring plasmapheresis in the acute phase and immunosuppressive agents for maintenance therapy. Optic neuropathy associated with primary Sjögren's syndrome may show variable clinical courses, including acute optic neuritis, insidious progression of chronic optic atrophy, or in the context of neuromyelitis optica spectrum disorders. Optic neuropathy may be the initial manifestation of primary Sjögren's syndrome without apparent sicca symptoms, which makes the diagnosis often difficult. The presence of specific antibodies including anti-Ro/SSA, anti-La/SSB, and anti-aquaporin-4 antibodies are supportive for the diagnosis and treatment in atypical cases of optic neuropathy.

    The chronic idiopathic urticaria treatment is a difficult and often frustrating problem for physicians. Due to the lack of definitive medical therapeutic programs to relieve the symptoms and prevent from their recurrence, several pharmacologic approaches to the management of chronic idiopathic urticaria are proposed. The chronic urticaria pharmacologic therapy is therefore fit to abrogate effects of histamine and other mediators on cutaneous vasculature and inflammatory cells that participate in the pathogenesis of the urticaria. The most common approach is to avoid all aggravating factors and to block histamine. The mainstay therapy is the H1 antihistamines. A significant number of patients may remain unresponsive even after an increase in the dose or a change in the type of H1 antihistaminic drug. In these cases, several therapies can be associated: combinations of H1 antihistamines, nonsedating one tablet (morning) and one sedating (evening), this approach is very usual but no study has confirmed it rational; addition an H2 antagonist to the previous treatment for some patients may improve control of their symptoms; alternatively, the tricyclic antidepressant, Doxepin is usually prescribed. The results of other drugs reported in the literature is unpredictable, to include them in a strategy therapy. The results with Badrenergic agents, nifedipine, ketotifen, leukotriene antagonists and tranexamic acid are variable and don't appear better than those with H1 antagonists. The efficiency of danazol has to be confirmed by other controlled studies. Warfarin, sulfasalazine and ultraviolet radiation have been used apparently successfully, but no controlled study has been published. Only when the above treatments have failed then immunosuppresive therapies, intravenous immunoglobulin and plasmapheresis can be proposed for chronic idiopathic urticaria.

    Encephalitis caused by anti-N-methyl-d-aspartate receptor (NMDAR) antibodies is the leading cause of immune-mediated encephalitis. There are limited data on intensive care unit (ICU) management of these patients. To identify prognostic factors of good neurologic outcome in patients admitted to an ICU with anti-NMDAR encephalitis. This was an observational multicenter study of all consecutive adult patients diagnosed with anti-NMDAR encephalitis at the French National Reference Centre, admitted to an ICU between 2008 and 2014. The primary outcome was a good neurologic outcome at 6 months after ICU admission, defined by a modified Rankin Scale score of 0-2. Seventy-seven patients were included from 52 ICUs. First-line immunotherapy consisted of steroids (n = 61/74; 82%), intravenous immunoglobulins (n = 71/74; 96%), and plasmapheresis (n = 17/74; 23%). Forty-five (61%) patients received second-line immunotherapy (cyclophosphamide, rituximab, or both). At 6 months, 57% of patients had a good neurologic outcome. Independent factors of good neurologic outcome were early (≤8 d after ICU admission) immunotherapy (odds ratio, 16.16; 95% confidence interval, 3.32-78.64; for combined first-line immunotherapy with steroids and intravenous immunoglobulins vs. late immunotherapy), and a low white blood cell count on the first cerebrospinal examination (odds ratio, 9.83 for 50 cells/mm 3 ; 95% confidence interval, 1.07-90.65). Presence of nonneurologic organ failures at ICU admission and occurrence of status epilepticus during ICU stay were not associated with neurologic outcome. The prognosis of adult patients with anti-NMDAR encephalitis requiring intensive care is good, especially when immunotherapy is initiated early, advocating for prompt diagnosis and early aggressive treatment.

    There is a wide spectrum of clinical manifestations in children with anti-N-methyl-d-aspartate (NMDA) receptor antibody encephalitis from two different health care settings. We describe our experience with 13 patients (median age, 7 years; range, 5 months to 19 years) presenting to tertiary referral centers in India and the United States. Initial manifestations were neurological (seizures or movement disorders) in eight patients, and psychiatric (e.g., emotional lability and hallucination) in five patients. Symptoms during the clinical course included seizures in ten patients, movement disorders (dyskinesia and choreiform movements) in 11 patients, and behavioral changes (aggressiveness and insomnia) in ten patients. Concomitant infections (herpes simplex virus 1, tuberculous meningitis, and influenza A) were present in three patients. Analysis of the cerebrospinal fluid in all except two cases preceded by infection (herpes simplex virus encephalitis and tuberculous meningitis) was unremarkable. Treatment included intravenous immunoglobulin/methylprednisolone (11 patients), rituximab (eight patients), plasmapheresis (two patients), and cyclophosphamide (two patients). Six patients recovered completely. Two patients had mild residual neurological deficits, whereas four had severe residual neurological deficits. Two patients had profound autonomic instability, which was the cause of death for one of them. Two patients relapsed at two and six months after the initial recovery. We describe the differences and similarities of clinical presentation, test results, and response to treatment of children with anti-N-methyl-d-aspartate receptor encephalitis from India and the United States. Included is a description of one of the youngest patients with anti-N-methyl-d-aspartate receptor encephalitis (five months) and the first patient to be reported in association with tuberculous meningitis.

      The extracellular hepatitis C virus (HCV)-antigen, including HCV-Core protein, can suppress immune cells. Recently, the efficacy of double filtration plasmapheresis (DFPP) for chronic hepatitis C (CHC) was reported. However, the mechanism of efficacy of DFPP might not be only the reduction of HCV but also the effect of immune cells via direct and/or indirect mechanisms. The aim of this study is to analyze the virological and immunological parameters of difficult-to-treat HCV patients treated with DFPP combined with Peg-interferon and RBV (DFPP/Peg-IFN/RBV) therapy.   Twelve CHC patients were enrolled and treated with DFPP/Peg-IFN/RBV therapy. The immunological, virological and genetic parameters were studied.   All patients (4/4) treated with the major IL28B allele (T/T) could achieve complete early virological response (EVR). The amounts of HCV-Core antigen in the peripheral blood of EVR patients treated with DFPP/Peg-IFN/RBV rapidly declined in comparison to those of late virological response (LVR) patients treated with DFPP/Peg-IFN/RBV and EVR patients treated with Peg-IFN and RBV (Peg-IFN/RBV). The amount of IFN-γ produced from peripheral blood gradually increased. On the other hand, the amount of IL10 gradually decreased in the EVR patients. The frequencies of HCV-Core binding on CD3+ T cells rapidly declined in EVR patients treated with DFPP/Peg-IFN/RBV therapy. Moreover, the distributions of activated CD4(+) and CD8(+) T cells and CD16-CD56 high natural killer cells were significantly changed between before and after DFPP.   The rapid reduction of HCV-Core antigens and changes in the distribution of lymphoid cells could contribute to the favorable immunological response during DFPP/Peg-IFN/RBV therapy. © 2011 The Japan Society of Hepatology.

    Age influences incidence and prognosis of Guillain Barre Syndrome (GBS), common cause of ascending areflexic quadriparesis. Dedicated studies on elderly GBS are infrequent. This study aimed to describe clinical features and outcome at hospital-discharge in patients aged≥60years with GBS. Medical records of 70 elderly GBS over 15years were analysed. Mean symptom-duration was 5.78±4.5days and onset-to-peak 5.14±4.4days. Antecedent events preceded GBS by 8.07±9.9days and included: fever (n=19), respiratory infection (n=6), and gastroenteritis (n=5). Clinical features were weakness of facial (n=34), bulbar (n=13), extraocular (n=4) and respiratory (n=20) muscles and recurrence (n=4). Nine had Hughes disability score (HDS) of three or less. Sensory symptoms and signs included paresthesias (n=40), pain (n=24), and impaired kinaesthetic sensation (n=14). Laboratory abnormalities included albumino-cytological dissociation (n=50), hyponatremia (n=36) and elevated creatine kinase (n=18). Electrophysiological subtypes were: primary demyelinating (n=52), inexcitable (n=3), equivocal (n=2) and axonal (n=1). Fifty-seven patients treated with plasmapheresis (n=48) or intravenous immunoglobulin (n=9) had mean HDS of 3.53±0.7 at discharge. Twenty-one were ambulant (HDS≥3), one had persisting respiratory weakness and one died. Striking differences between the 'elderly' and 100 'adults' seen over 20months were shorter symptom-duration, higher frequency of facial palsy and hyponatremia, lower frequency of pain, lower mean MRC sum score and worse HDS at study-entry and discharge (p<0.05). Requirement for mechanical ventilation and cardiac autonomic dysfunction was higher among elderly (p:0.02). In conclusion, in this cohort of elderly GBS, there was a higher frequency severe GBS and demyelinating electrophysiology. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Guillain-Barre syndrome is classically defined as a symmetrical ascending acute polyradiculoneuropathy, although there are atypical variants that make diagnosis difficult. The medical data of six patients in our hospital area are collected during the first quarter of 2013. Lumbar punctures, imaging, neurophysiological studies, ganglioside antibodies and serologies have been proposed in all cases. We focus on the atypical features as late hyporeflexia, increased frequency of asymmetry and distal paresis and initial fever. From a neurophysiological point of view, all patients presented sensorimotor axonal forms. The most consistent datas in early studies is the F wave's alteration. A Miller Fisher variant associated with faciocervicobraquial paresis and cerebral reversible vasoconstriction syndrome has been detected. A bilateral brachial paresis and lumbar polyradiculopathy in the context of influenza A infection is other interesting case. The saltatory variant with cranial nerve involvement and lower limbs paresis has been demonstrated in one patient. Bands in cerebrospinal fluid are positive in three cases and anti-ganglioside antibodies in one patient. The syndrome of inappropriate secretion of antidiuretic hormone may explain some of the hyponatremias registered. The first line of treatment are inmunoglobulins in all patients. Plasmapheresis exchanges has been used as an additional therapy in four cases. These clusters of six axonal cases with atypical clinical features justifies the need for knowledge of these variants in order to achieve an early treatment. Late hyporeflexia and brachialfaciocervico, saltatory and lumbar forms should be considered in the spectrum of Guillain-Barre syndrome. The etiological study should rule out a lots of pathogens as influenza A.

    Practice guidelines reflect published literature. Because of the ever changing literature base, it is necessary to update and revise guideline recommendations from time to time. The Society of Thoracic Surgeons recommends review and possible update of previously published guidelines at least every three years. This summary is an update of the blood conservation guideline published in 2007. The search methods used in the current version differ compared to the previously published guideline. Literature searches were conducted using standardized MeSH terms from the National Library of Medicine PUBMED database list of search terms. The following terms comprised the standard baseline search terms for all topics and were connected with the logical 'OR' connector--Extracorporeal circulation (MeSH number E04.292), cardiovascular surgical procedures (MeSH number E04.100), and vascular diseases (MeSH number C14.907). Use of these broad search terms allowed specific topics to be added to the search with the logical 'AND' connector. In this 2011 guideline update, areas of major revision include: 1) management of dual anti-platelet therapy before operation, 2) use of drugs that augment red blood cell volume or limit blood loss, 3) use of blood derivatives including fresh frozen plasma, Factor XIII, leukoreduced red blood cells, platelet plasmapheresis, recombinant Factor VII, antithrombin III, and Factor IX concentrates, 4) changes in management of blood salvage, 5) use of minimally invasive procedures to limit perioperative bleeding and blood transfusion, 6) recommendations for blood conservation related to extracorporeal membrane oxygenation and cardiopulmonary perfusion, 7) use of topical hemostatic agents, and 8) new insights into the value of team interventions in blood management. Much has changed since the previously published 2007 STS blood management guidelines and this document contains new and revised recommendations. Copyright © 2011 The Society of Thoracic

    Full Text Available IntroductionA 60-year-old man presented with a 6-month history of low back pain and progressive rigidity of the trunk and lower limbs, followed by pruritus, dysphonia, hyperhydrosis, and urinary retention. Brain and spinal imaging were normal. EMG showed involuntary motor unit hyperactivity. Onconeural, antiglutamic acid decarboxylase (anti-GAD, voltage-gated potassium channel, and dipeptidyl peptidase-like protein 6 (DPPX autoantibodies were negative. CSF was negative. Symptoms were partially responsive to baclofen, gabapentin, and clonazepam, but he eventually developed severe dysphagia. Antiglycine receptor (anti-GlyR antibodies turned out positive on both serum and CSF. A plasmapheresis cycle was completed with good clinical response. A PET scan highlighted an isolated metabolically active axillary lymphnode that turned out to be a classic type Hodgkin lymphoma (HL, in the absence of bone marrow infiltration nor B symptoms. Polychemotherapy with ABVD protocol was completed with good clinical response and at 1-year follow-up the neurological examination is normal.BackgroundProgressive encephalomyelitis with rigidity and myoclonus (PERM is a rare and severe neurological syndrome characterized by muscular rigidity and spasms as well as brain stem and autonomic dysfunction. It can be associated with anti-GAD, GlyR, and DPPX antibodies. All of these autoantibodies may be variably associated with malignant tumors and their response to immunotherapy, as well as to tumor removal, is not easily predictable.ConclusionProgressive encephalomyelitis with rigidity and myoclonus has already been described in association with HL, but this is the first case report of a HL manifesting as anti-GlyR antibodies related PERM. Our report highlights the importance of malignancy screening in autoimmune syndromes of suspected paraneoplastic origin.

  9. Kinetic Targeting of pegylated liposomal Doxorubicin: a new Approach to Reduce Toxicity during Chemotherapy (CARL-trial

    2011-08-01

    Full Text Available Abstract Background The therapeutic success of chemotherapeutic agents is often limited by severe adverse effects. To reduce toxicity of these drugs, nanoscale particle-based drug delivery systems (DDS are used. DDS accumulate to some extent in tumor tissues, but only a very small portion of a given dose reaches this target. Accumulation of DDS in tumor tissues is supposed to be much faster than in certain other tissues in which side effects occur ("Kinetic Targeting". Once saturation in tumor tissue is achieved, most of the administered DDS still circulate in the plasma. The extracorporeal elimination of these circulating nanoparticles would probably reduce toxicity. Methods For the CARL-trial (Controlled Application and Removal of Liposomal chemotherapeutics, pegylated liposomal doxorubicin (PLD was used as chemotherapeutic agent and double filtration plasmapheresis (DFPP was performed for extracorporeal elimination of liposomes. PLD was given as 40 mg/m2 every 3 weeks in combination with vinorelbine 2 × 25 mg/m2 (neoadjuvant treatment of breast cancer, 12 patients, or as 40 mg/m2 every 4 weeks (recurrent ovarian cancer, 3 patients. Primary endpoints were the efficiency and safety profile of DFPP, and secondary endpoints were side effects and tumor response. Results DFPP eliminated ~62% of circulating PLD, corresponding to ~45% of the total dose (n = 57 cycles. AUC of doxorubicin was reduced by 50%. No leakage of doxorubicin was detected during elimination, and no relevant DFPP-related side effects occurred. Reduction in tumor size > 30% occurred in 10/12 (neoadjuvant and in 1/3 patients (recurrent. Only five grade 2 events and one grade 3 event (mucositis, neutropenia or leucopenia and a single palmar-plantar erythrodysesthesia grade 2 were reported. Conclusion Extracorporeal elimination of PLD by DFPP is safe and efficient. CARL can diminish the main dose-limiting side effects of PLD, and probably many different DDS alike. Trial

  10. Wegener’s granulomatosis and pyoderma gangrenosum – rare causes of facial ulcerations

    Directory of Open Access Journals (Sweden)

    Karolina Kędzierska

    2016-03-01

    Full Text Available Background: Pyoderma gangrenosum (PG is caused by immune system dysfunction, and particularly improper functioning of neutrophils. At least half of all PG patients also suffer from autoimmunological diseases, one of which is Wegener granulomatosis (WG. The purpose of this article was to compare cases of patients with WG and PG in terms of their clinical course, histopathology, and applied treatment. In both, histopathological features are not fully distinct. Data from microbiological and immunological evaluation and clinical presentation are required to establish the diagnosis. We also present the case of a patient with WG and deep facial skin lesions not responding to standard treatment. Methods: Systematic review of the literature in PubMed using the search terms “Wegener granulomatosis AND Pyoderma gangrenosum” and case report. Results: The finding of 22 reports in the literature (PubMed suggests that it is a rare phenomenon. This study revealed a similar rate of comorbidity of WG and PG in both genders and an increased incidence of both diseases after the age of 50. Among skin lesions there was a dominance of ulceration, most often deep and painful, covering a large area with the presence of advanced necrosis and destruction of the surrounding tissue. The most common location proved to be the cervical-cephalic area. The most popular treatment included steroids with cyclophosphamide. Discussion: The rarity of the coexistence of these two diseases results in a lack of effective therapy. In such cases sulfone derivatives are still effective and provide an alternative to standard immunosuppression methods. Hyperbaric therapy and plasmapheresis can also play an important complementary role.

    Full Text Available Background: Recurrent focal segmental glomerular sclerosis (rFSGS in renal transplant recipients (RTR is difficult to predict and treat. Early rFSGS is likely from circulating factors and preformed antibodies. Methods: We present the case of a 23-year-old white man who presented with rFSGS and acute renal failure requiring dialysis 9-months after a 1-haplotype matched living-related transplant. We retrospectively analyzed serum samples from various clinical stages for rFSGS biomarkers: serum glomerular albumin permeability (Palb, soluble urokinase-type plasminogen activator receptor (suPAR serum level with suPAR-β3 integrin signaling on human podocytes, and angiotensin II type I receptor-antibody (AT1R-Ab titer. Results: All biomarkers were abnormal at 1-year pre-transplant prior to initiation of dialysis and at the time of transplant. After initiation of hemodialysis, β3 integrin activity on human podocytes, in response to patient serum, as well as AT1R-Ab were further elevated. At the time of biopsy-proven recurrence, all biomarkers were abnormally high. One week after therapy with aborted plasmapheresis (secondary to intolerance, and high dose steroids, the Palb and suPAR- β3 integrin activity remained significantly positive. After 12-weeks of treatment with high-dose steroids, rituximab, and galactose, the patient remained hemodialysis-dependent. Three-months after his initial presentation we commenced adrenocorticotropic hormone (ACTH, Acthar® Gel, 80 units subcutaneously twice weekly. Four-weeks later he was able to discontinue dialysis. After 8-months of maintenance ACTH therapy, his serum creatinine stabilized at 1.79 mg/dL with less than 1 gram of proteinuria. Conclusion: ACTH therapy was associated with improvement in renal function within 4 weeks. The use of rFSGS biomarkers may aid in predicting development of rFSGS.

    Full Text Available Andrea P Mann,1 Elena Grebenciucova,2 Rimas V Lukas21Department of Psychiatry and Behavioral Neuroscience, 2Department of Neurology, University of Chicago, Chicago, IL, USAObjective: Anti-N-methyl-D-aspartate-receptor (NMDA-R encephalitis is a new autoimmune disorder, often paraneoplastic in nature, presenting with complex neuropsychiatric symptoms. Diagnosed serologically, this disorder is often responsive to immunosuppressant treatment. The objective of this review is to educate clinicians on the challenges of diagnosis and management of this disorder.Materials and methods: A review of the relevant literature on clinical presentation, pathophysiology, and recommended management was conducted using a PubMed search. Examination of the results identified articles published between 2007 and 2014.Results: The literature highlights the importance of recognizing early common signs and symptoms, which include hallucinations, seizures, altered mental status, and movement disorders, often in the absence of fever. Although the presence of blood and/or cerebrospinal fluid autoantibodies confirms diagnosis, approximately 15% of patients have only positive cerebrospinal fluid titers. Antibody detection should prompt a search for an underlying teratoma or other underlying neoplasm and the initiation of first-line immunosuppressant therapy: intravenous methylprednisolone, intravenous immunoglobulin, or plasmapheresis, or a combination thereof. Second-line treatment with rituximab or cyclophosphamide should be implemented if no improvement is noted after 10 days. Complications can include behavioral problems (eg, aggression and insomnia, hypoventilation, catatonia, and autonomic instability. Those patients who can be managed outside an intensive care unit and whose tumors are identified and removed typically have better rates of remission and functional outcomes.Conclusion: There is an increasing need for clinicians of different specialties, including

    Full Text Available Abstract Hydralazine is a direct-acting vasodilator, which has been used in treatment for hypertension (HTN since the 1950s. While it is well known to cause drug-induced lupus (DIL, recent reports are indicating the emergence of the drug-induced anti-neutrophil cytoplasmic antibody (ANCA associated vasculitis (DIV. Herein, we describe two patients (aged 57 and 87 years who presented with severe acute kidney injury (AKI, proteinuria, and hematuria. Both were receiving hydralazine for the treatment of hypertension. ANCA serology was positive in both patients along with anti-histone antibodies (commonly seen in drug-induced vasculitis. Renal biopsy revealed classic crescentic (pauci-immune glomerulonephritis in these patients and hydralazine was discontinued. During the hospital course, the 57-year-old patient required dialysis therapy and was treated with steroids and rituximab for the ANCA disease. Renal function improved and the patient was discharged (off dialysis with a serum creatinine of 3.6 mg/dL (baseline = 0.9 mg/dL. At a follow-up of 2 years, the patient remained off dialysis with advanced chronic kidney disease (CKD (stage IIIb. The 87-year-old patient had severe AKI with serum creatinine at 10.41 mg/dL (baseline = 2.27 mg/dL. The patient required hemodialysis and was treated with steroids, rituximab, and plasmapheresis. Unfortunately, the patient developed catheter-induced bacteremia and subsequently died of sepsis. Hydralazine can cause severe AKI resulting in CKD or death. Given this extremely unfavorable adverse-event profile and the widespread availability of alternative anti-hypertensive agents, the use of hydralazine should be carefully considered.

    Full Text Available Nephrogenic systemic fibrosis (NSF is a relatively new fibrosing disorder which has caught the attention of various specialities in the past decade. NSF is an extremely disabling and often painful condition, affecting up to 13% of the individuals with chronic kidney disease. The administration of a gadolinium chelate contrast agent has been reported to induce the development of NSF, particularly in patients who have acute or chronic renal disease with a glomerular filtration rate (GFR lower than 30-mL/min/1.73 m 2 and in those with acute renal insufficiency. Mass spectroscopy studies have demonstrated particles of gadolinium in the lesional tissue. The exact pathogenesis of this curious sclerosing condition is unknown. The role of the aberrant targeting of ′circulating fibrocytes′ to the peripheral tissues and viscera has been hypothesized. NSF has distinct clinicopathological features in the setting of renal failure and needs to be looked upon as a new entity on the block. The condition is characterized by irregular indurated plaques, with amoeba-like projections and islands of sparing, chiefly on the trunk and extremities. Flexion contractures of fingers, knees, and elbow joints are known to occur in advanced cases of NSF. The course is frequently associated with painful episodes and loss of ambulation. Histopathology shows haphazard arrangement of thickened bundles of collagen, varying amount of mucin, and increased population of fibroblast-like cells in the dermis. Immunohistochemistry shows increased deposition of type-I procollagen and CD 34+ cells having fibroblastic activity. The condition is refractory to treatment with corticosteroids and immunosuppressive agents. Various modalities of therapy such as UVA1 phototherapy, imatinib mesylate, photodynamic therapy, plasmapheresis, extracorporeal photochemotherapy, and high-dose intravenous immunoglobulin have shown a moderate degree of improvement in skin thickness scores.

    Therapeutic plasma exchange (TPE) is performed frequently and effectively in developed countries, whereas the reverse is the case in developing countries. Guillain-Barre syndrome (GBS), synonymous with acute inflammatory demyelinating polyneuropathy, is an important indication for TPE, but this is rarely administered in the treatment of such patients in Nigeria due to lack of such automated facility, limited expertise, and high cost. This report therefore presents an uncommon case of GBS in which automated TPE was utilized in the management, with the aims of highlighting the current status and challenges of therapeutic apheresis services in Nigeria. A 42-year-old male presented with rapidly progressive (in an ascending fashion) paralysis of all four limbs within 24 h without any preceding history of fever or other symptoms. Clinical examination revealed a young man, afebrile, not pale, and also not dehydrated. Central nervous system examination showed a conscious man, alert, and oriented in time, person, and place. There were no signs of meningeal irritation and the cranial nerves were grossly intact. There was no power in the limbs: global hypotonia and areflexia were noted on examination. However, he had intact sensory perceptions to touch and pain. Following a diagnosis of GBS, he was treated with four sessions of plasmapheresis and TPE. The TPE session was done using a discontinuous flow apheresis machine which exchanged one plasma volume (3 L of plasma) and 5% albumin used for replacement. The patient made gradual but steady recovery as return of power to the upper limbs and trunk started by the 2nd week of treatment. TPE is an important treatment modality in the management of GBS as well as several other conditions, and it is becoming increasingly available in Nigeria. However, it is still grossly underutilized, thus the need for more therapeutic apheresis facilities and trained personnel, in addition to concerted efforts to subsidize the cost of accessing

    More than 30% of potential kidney transplant recipients have pre-existing anti-human leukocyte antigen antibodies. This subgroup has significantly lower transplant rates and increased mortality. Desensitization has become an important tool to overcome this immunological barrier. However, limited data is available regarding long-term outcomes, in particular for the highest risk group with a positive complement-dependent cytotoxicity crossmatch (CDC XM) before desensitization. Between 2002 and 2010, 39 patients underwent living-kidney transplantation across a positive CDC XM against their donors at our center. The desensitization protocol involved pretransplant immunosuppression, plasmapheresis, and low-dose intravenous immunoglobulin±rituximab. Measured outcomes included patient survival, graft survival, renal function, rates of rejection, infection, and malignancy. The mean and median follow-up was 5.2 years. Patient survival was 95% at 1 year, 95% at 3 years, and 86% at 5 years. Death-censored graft survival was 94% at 1 year, 88% at 3 years, and 84% at 5 years. Uncensored graft survival was 87% at 1 year, 79% at 3 years, and 72% at 5 years. Twenty-four subjects (61%) developed acute antibody-mediated rejection of the allograft and one patient lost her graft because of hyperacute rejection. Infectious complications included pneumonia (17%), BK nephropathy (10%), and CMV disease (5%). Skin cancer was the most prevalent malignancy in 10% of patients. There were no cases of lymphoproliferative disorder. Mean serum creatinine was 1.7±1 mg/dL in functioning grafts at 5 years after transplantation. Despite high rates of early rejection, desensitization in living-kidney transplantation results in acceptable 5-year patient and graft survival rates.

    This present case pertains to a 48-year-old woman with a history of antiphospholipid syndrome, who presented with progressive fatigue, generalized weakness, and orthopnea acutely. She had a prior diagnosis of antiphospholipid syndrome with recurrent deep vein thromboses (DVTs) and repeated demonstration of lupus anticoagulants. She presented in cardiogenic shock with markedly elevated troponin and global myocardial dysfunction on echocardiography, and cardiac catheterization revealed minimal disease. Cardiac magnetic resonance imaging was performed, which revealed findings of perfusion defects and microvascular obstruction, consistent with the pathophysiology of catastrophic antiphospholipid syndrome (CAPS). Diagnosis was made based on supportive imaging, including head magnetic resonance imaging (MRI) revealing multifocal, acute strokes; microvascular thrombosis in the dermis; and subacute renal infarctions. The patient was anticoagulated with intravenous unfractionated heparin and received high-dose methylprednisolone, plasmapheresis, intravenous immunoglobulin, and one dose each of rituximab and cyclophosphamide. She convalesced with eventual myocardial recovery after a complicated course. The diagnosis of CAPS relies on the presence of (1) antiphospholipid antibodies and (2) involvement of multiple organs in a microangiopathic thrombotic process with a close temporal association. The myocardium is frequently affected, and heart failure, either as the presenting symptom or cause of death, is common. Despite echocardiographic evidence of myocardial dysfunction in such patients, MRIs of CAPS have not previously been reported. This case highlights the utility in assessing the involvement of the myocardium by the microangiopathic process with MRI. Because the diagnosis of CAPS requires involvement in multiple organ systems, cardiac MRI is likely an underused tool that not only reaffirms the pathophysiology of CAPS, but could also clue clinicians in to the

    Antiphospholipid syndrome (APS) is associated with pregnancy complications such as recurrent early fetal loss (RFL), fetal death, preeclampsia (PE), and intrauterine growth restriction (obstetric APS/OAPS). Other clinical manifestations are venous and/or arterial thromboses (thrombotic APS/TAPS). The data of 37 pregnancies with OAPS and 37 pregnancies with TAPS were analyzed and compared. Overall, the most frequent APS antibodies (aPl) were LA as well as "triple-positivity"; LA antibodies were significantly more frequent in women with TAPS (67.6 % TAPS vs. 29.7 % OAPS, p < 0.010), whereas "triple-positivity" was significantly more seen in women with OAPS (40.5 % OAPS vs. 13.5 % TAPS, p < 0.010). Adequate therapy has been administered in nearly all pregnancies with TAPS, whereas in 18.9 % of pregnancies with OPS, no therapy has been given at all. One woman in OAPS and four women in TAPS were treated with plasmapheresis and immunoadsorption. There was no significant association between adverse obstetric outcome and therapy. The most frequent pregnancy complications were RFL in the OAPS group (32.4 vs. 13.5 % in TAPS) and PE in the TAPS group (18.9 % in OAPS and TAPS, respectively). The data of our study showed that pregnancies with OAPS and TAPS have a similar rate of pregnancy complications. However, pregnancies with OAPS tend to have rather RFL. Although we were not able to reveal a significant association with adverse obstetric outcome, it seems that the current adequate therapy for APS in pregnancy, consisting of LDA and LMWH, might rather prevent the development of RFL. Additionally, it might be considered to divide the obstetric APS into obstetric APS with early pregnancy complications and obstetric APS with late pregnancy complications. The division into two groups of obstetric APS might facilitate the choice of additional therapy in these women.

  19. L-Tryptophan depletion bioreactor, a possible cancer therapy

    Full Text Available The cancer therapeutic strategies knownto date are not adequate for all cancer patients. Most of them are followed by a high rate of side effects and complications. The L-tryptophan depletion bioreactor is described as a possible new method of cancer therapy. L-tryptophan is an essential amino acid which has been recognized as an important cancer nutrient and its removal can lead to destruction of the tumour. Normal human cells or tumor cells cannot synthesize L-tryptophan and therefore tumor resistance is unlikely to develop. L-tryptophan is also a constituent for different bio-molecules such as Serotonin, Melatonin, and is needed for other synthesis processes in the cell growth. L-tryptophan degrading enzymes with 3 iso-enzymes called tryptophan side chain oxydase (TSO I, II, III were isolated. The 3 iso-enzymes can be differentiated by tryptic digestion. They have different molecular weights with different effectivenesses. All the TSO enzymes have heme that can catalyze essentially similar reactions involving L-tryptophan as a substrate. The most effective TSO is the type TSO III. A column which contained TSO as a bioreactor was integrated in a plasmapheresis unit and tested it in different animals. In sheep and rabbits L-tryptophan depletion in plasma was shown at 95% and 100% rates respectively by a single pass through the bioreactor. The results in immune supprimized rats with tumors were impressive, too. In 20 different tumor cell lines there were different efficacies. Brest cancer and medulloblastoma showed the greatest efficacy of L-tryptophan degrading. The gene technology of TSO production from Pseudomonas is associated with formation of endotoxins. This disadvantage can be prevented by different washing procedures or by using fungal sources for the TSO production. TSO III is developed to treat cancer diseases successfully, and has low side effects. A combination of L-tryptophan depletion with all available cancer therapies is

    Pulmonary hemorrhage (PH) occurs in 2-5% of SLE patients, and is associated with a high mortality rate (79-90%). Diagnostic criteria for this complication include: 1) Pulmonary infiltrates, with at least ¾ of lung tissue involved in a chest x ray, 2) Acute respiratory failure, 3) A decrease of 3g/dL or more in hemoglobin levels. PH might lead to organized pneumonia, collagen deposition, and pulmonary fibrosis which in time might cause changes in pulmonary function tests with either restrictive or obstructive patterns. To evaluate the existence of abnormalities in pulmonary function tests after a PH episode. We included patients with SLE and primary vasculitis that developed PH. During the acute episode, we measured SLEDAI in SLE patients, five factor score in microscopic polyangiitis (MPA) and Birmingham Vasculitis Activity Store (BVAS) in granulomatosis with polyangiitis (GPA) (Wegener). We determined the number of PH events, treatment, and ventilator assistance requirements and correlated its association with abnormal pulmonary function tests. We included 10 patients, 7 with SLE, 2 with MPA and 1 with GPA (Wegener). The mean activity measures were: SLEDAI 20.4 ± 7.5, FFS 2, and BVAS 36. Treatment consisted in methylprednisolone (MPD) in 3 patients, MPD plus cyclophosphamide (CY) in 6 patients, and MPD, CY, IV immunoglobulin, and plasmapheresis in one patient. Five patients required ventilatory support. We found abnormalities in pulmonary function tests in 8 patients, three had an obstructive pattern and five a restrictive pattern; 2 patients did not show any change. We did not find a significant association with any of the studied variables. PH might cause abnormalities in pulmonary function tests and prolonged immunosuppressive treatment could be required.

    The aim of this work is to improve the results of diagnosis and surgical treatment of mediastinal thymomas. With this reason, 128 patients with the tumors of thymus have been undergone operations at the Thoracic Department of the National Cancer Centre (NCC) of Georgia. Material and methods: Out of 128 patients, type A thymomas were diagnosed in 7, type AB - in 14, type B1 - in 52, typer B2 - in 32, type B3 - in 18 patients. Myasthenia was revealed in 51 patients. Most frequently myasthenia was found in type B1 (48.1%) and in type B2 (40.8%) thymomas while in type A and type AB - in 28.6% and in 28.5% correspondingly, but in type B3 myasthenia was found in 16.7%. Results: Helical Computerized Tomography (CT) is leading in diagnosis of mediastinal thymomas. Surgical method in the volume of thymomtymectomy is the best choice of treatment of thymomas and it is performed basically by sternotomic approach. The effectiveness of surgical treatment depended upon the optimization of patients presurgical preparing and it often included steroidal therapy and plasmapheresis. The period of post surgical liquidation of myasthenia signs was between 1 - 14 months. The remote results of treatment depend on histological type of tumor and its stage. At I-II stages of A and AB type thymomas, 100% of patients survived 5 and more years after radical operation, while in III stage - 86%. 5-year survival rate was 95-97% in thymomas of B1-3 types stage I, but at stage III it was no more than 38%.

    Myasthenia gravis is an autoimmune disease caused by antibodies leading to the destruction of nicotinic acetylcholine receptors on the neuromuscular junction. It is characterized by muscle weakness that gets aggravated with physical activity and improves at rest. Myasthenia Gravis Foundation of America made the clinical classification of Myasthenia gravis which is still in use today. "Tensilon test" is still the gold standard for the diagnosis of Myasthenia gravis. In addition to this test repeated muscular stimulation can be used as well as the analysis of specific autoantibodies. Treatment of Myasthenia Gravis. In conservative treatment of Mysthenia gravis anticholinesterases, immunosuppressants and plasmapheresis can be used. If conservative treatment does not lead to the desired remission, surgical treatment is indicated. The most accepted indication for thymectomy is the presence of thymoma with generalized form of Myasthenia gravis in adults.

    The role of autoimmune responses against central nervous system (CNS) antigens in encephalitis presenting with non-classified neurologic or psychiatric symptoms has been appreciated in the past decade. Paraneoplastic limbic encephalitis has a poor prognosis and is most commonly associated with lung, ovarium, and testicular neoplasms, leading to immune reactions against intracellular antigens (anti-Hu/ANNA1, anti-Ri/ANNA2, anti-CV2/CRMP5 and anti-Ma2/Ta). In contrast, the recently described autoimmune encephalitis subtypes present with a broad spectrum of symptoms, respond to autoimmune therapies well and usually associate with autoantibodies against neuronal cell surface receptors (NMDAR, GABA B R, AMPAR) or synaptic proteins (LGI1, CASPR2). Our aim is to bring to awareness the increasing number of autoimmune encephalitis patients requiring neurologic, psychiatric and intensive care and to emphasize the significance of detecting various autoantibodies in diagnosing patients. In the past 6 years, our laboratory received 836 autoimmune encephalitis diagnostic test requests from a total of 717 patients. Serum and cerebrospinal fluid (CSF) samples were analysed with indirect immunofluorescence using a BIOCHIP consisting of cell lines transfected with 6 different receptor proteins. IgG autoantibodies against receptor proteins were present in 7.5% of patients. The frequency of positive samples was the following: NMDAR > LGI1 > GABA B R > CASPR2. Detecting autoantibodies facilitates the diagnosis of autoimmune encephalitis in an early stage. Patients diagnosed early can be effectively treated with plasmapheresis and immunosuppressive drugs. The efficiency of therapies can be monitored by autoantibody detection. Therefore, the diagnostic immune laboratory plays an important role in proper diagnosis and in the prevention of rapidly progressing symptoms. Orv Hetil. 2018; 159(3): 107-112.

    Full Text Available Organ donors are sometimes found “unsuitable” due to the presence of donor-specific anti-HLA antibodies in the recipient. In recent years, improved desensitization protocols have successfully helped to overcome HLA incompatibility hurdle. We present three cases where optimum desensitization was achieved in patients with the donor-specific anti-HLA antibody (DSA leading to successful renal transplantation. All patient–donor pair underwent HLA typing, complement dependent cytotoxicity crossmatch (CDC-XM, flow cytometry XM (FC-XM, and panel reactive antibody. If any of the three tests was positive, single antigen bead assay was performed to determine the specificity of the anti-HLA antibody (s. Patients with DSA were offered organ-swap or anti-HLA antibody desensitization followed by transplantation. Desensitization protocol consisted of single dose rituximab and cascade plasmapheresis (CP along with standard triple immunosuppression. The target DSA mean fluorescence index (MFI was <500, along with negative CDC-XM and FC-XM for both T- and B-cells. Three patients with anti-HLA DSA, who did not find a suitable match in organ swap program, consented to anti-HLA antibody desensitization, followed by transplantation. Mean pre-desensitization antibody MFI was 1740 (1422–2280. Mean number of CP required to achieve the target MFI was 2.3 (2–3. All the three patients are on regular follow-up and have normal renal function test at a mean follow-up of 8 months. This report underlines successful application of desensitization protocol leading to successful HLA-antibody incompatible renal transplants and their continued normal renal functions.

    Full Text Available El síndrome pulmón-riñón se define como una combinación de hemorragia alveolar difusa y glomerulonefritis. La coexistencia de estas dos afecciones clínicas se produce por enfermedades con distintos mecanismos patogénicos. Las vasculitis sistémicas primarias y el síndrome de Goodpasture son las etiologías más frecuentes. El lupus eritematoso sistémico, otras colagenopatías, las vasculitis con anticuerpos anticitoplasma de los neutrófilos negativos y las secundarias a drogas son causas mucho menos comunes. El diagnóstico temprano basado en criterios clínicos, radiológicos, de laboratorio e histológicos, permite iniciar el tratamiento disminuyendo su elevada morbi-mortalidad. La terapéutica se basa en altas dosis de corticoides, inmunosupresores, inhibidores del factor de necrosis tumoral y plasmaféresis.The pulmonary-renal syndrome is defined as a combination of diffuse alveolar hemorrhage and glomerulonephritis. The coexistence of these two clinical conditions is due to diseases with different pathogenic mechanisms. Primary systemic vasculitis and Goodpasture syndrome are the most frequent etiologies. Systemic lupus erythematosus, connective tissue diseases, negative anti neutrophil cytoplasmic antibody vasculitis and those secondary to drugs are far less common causes. An early diagnosis based on clinical, radiologic, laboratory and histologic criteria enables early treatment, thus diminishing its high morbility-mortality rate. Therapy is based on high doses of corticosteroids, immunosuppressants, tumor necrosis factor inhibitors and plasmapheresis.

    Researches on blood purification membranes are fuelled by diverse clinical needs, such as hemodialysis, hemodiafiltration, hemofiltration, plasmapheresis, and plasma collection. To approach high-performance dialyzer, the integrated antifouling and antithrombotic properties are highly necessary for the design/modification of advanced artificial membranes. In this study, we propose and demonstrate that the physical blend of triblock polyurethane (PU) and polyethersulfone (PES) may advance the performance of hemodialysis membranes with greatly enhanced blood compatibility. It was found that the triblock PU could be blended with PES at high ratio owing to their excellent miscibility. The surfaces of the PES/PU composite membranes were characterized using attenuated total reflectance-Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, water contact angle measurement, and surface ζ-potentials. The results indicated that the membrane surfaces were assembled with hydrophilic segregation layer owing to the migration of amphiphilic PU segments during membrane preparation, which might confer the composite membranes with superior hemocompatibility. The cross-section scanning electron microscopy images of the composite membranes exhibited structure transformation from finger-like structure to sponge-like structure, which indicated that the composite membrane had tunable porosity and permeability. The further ultrafiltration experiments indicated that the composite membranes showed increased permeability and excellent antifouling ability. The blood compatibility observation indicated that PES/PU composite membranes owned decreased protein adsorption, suppressed platelet adhesion, and prolonged plasma recalcification time. These results indicated that the PES/PU composite membranes exhibited enhanced antifouling and antithrombotic properties than the pristine PES membrane. The strategy may forward the fabrication of blood compatible composite membranes for

    Full Text Available Abstract Introduction Goodpasture's disease is a rare immunological disease with formation of pathognomonic antibodies against renal and pulmonary basement membranes. Cerebral involvement has been reported in several cases in the literature, yet the pathogenetic mechanism is not entirely clear. Case presentation A 21-year-old Caucasian man with Goodpasture's disease and end-stage renal disease presented with two generalized seizures after a period of mild cognitive disturbance. Blood pressure and routine laboratory tests did not exceed the patient's usual values, and examination of cerebrospinal fluid was unremarkable. Cerebral magnetic resonance imaging (MRI revealed multiple cortical and subcortical lesions on fluid-attenuated inversion recovery sequences. Since antiglomerular basement membrane antibodies were found to be positive with high titers, plasmapheresis was started. In addition, cyclophosphamide pulse therapy was given on day 13. Encephalopathy and MRI lesions disappeared during this therapy, and antiglomerular basement membrane antibodies were significantly reduced. Previous immunosuppressive therapy was performed without corticosteroids and terminated early after 3 months. The differential diagnostic considerations were cerebral vasculitis and posterior reversible encephalopathy syndrome. Vasculitis could be seen as an extrarenal manifestation of the underlying disease. Posterior reversible encephalopathy syndrome, on the other hand, can be triggered by immunosuppressive therapy and may appear without a hypertensive crisis. Conclusion A combination of central nervous system symptoms with a positive antiglomerular basement membrane test in a patient with Goodpasture's disease should immediately be treated as an acute exacerbation of the disease with likely cross-reactivity of antibodies with the choroid plexus. In our patient, a discontinuous strategy of immunosuppressive therapy may have favored recurrence of Goodpasture's disease.

    For desensitization of ABO-incompatible kidney transplant recipients we recently proposed nonantigen-specific immunoadsorption (IA) and rituximab. We now compared clinical outcomes of 34 ABO-incompatible living-donor kidney recipients who were transplanted using this protocol with that of 68 matched ABO-compatible patients. In addition, we analyzed efficacy and cost of nonantigen-specific as compared to blood group antigen-specific IA. Before desensitization, the median isoagglutinin titer of 34 ABO-incompatible patients was 1:64 (Coombs technique). Patients received a median of 7 preoperative IA treatments. Twenty-four patients had a median of 2 additional plasmapheresis treatments to reach the preoperative target isoagglutinin titer of 1:8 or less. After a median postoperative follow-up of 22 months, overall graft survival in the ABO-incompatible group was not significantly different from that in ABO-compatible patients (log-rank P = 0.20), whereas patient survival tended to be lower (log-rank P = 0.05). The incidence of rejection episodes was 15% in both groups. The ABO-incompatible kidney recipients had a higher incidence of BK virus replication (P = 0.04) and nephropathy (P = 0.01) and showed more often colonization with multidrug resistant bacteria (P = 0.02). In comparison to blood group antigen-specific IA, nonantigen-specific IA showed equal efficacy but was associated with reduction in cost. Clinical outcomes of ABO-incompatible patients desensitized with a nonantigen-specific IA device and rituximab do not differ from that of matched ABO-compatible patients although a trend toward reduced patient survival was noted. Special attention must be paid to the higher incidence of BK virus infection in recipients of ABO-incompatible grafts.

    Kidney transplantation is the better option for end-stage renal disease (ESRD), but for patients with human leukocyte antigen (HLA) sensitization, the wait times are significantly longer than for patients without antibodies. Many desensitization protocols have been described involving strong immunosuppression, the use of apheresis, and B-cell-modulating therapies. We have designed a desensitization protocol from day 0 for deceased donor kidney transplantation. Our aim was to present our initial experience with five kidney transplant patients. All patients had a negative complement-dependent cytotoxicity cross-match. The desensitization protocol included five to seven doses of thymoglobulin (1.25 mg/kg) and three sessions of plasmapheresis (PP) within the first week after transplantation, with intravenous immunoglobulin (500 mg/kg) after each PP session and one dose of rituximab on day 8. The presence of donor-specific antibodies (DSA) was analyzed by use of Luminex technology; levels between 1000 and 3000 mean fluorescence intensity were considered for desensitization. The median age was 44 years and median renal replacement therapy time was 9 years. All recipients presented 1 to 3 DSA specificities. There were no severe side effects related to PP, infusion of intravenous immunoglobulin, or rituximab. The median follow-up period was 19.3 months. Median serum creatinine level at last follow-up was 1.7 mg/dL. A kidney biopsy was performed in all patients. Graft and patient survival was 100%. Until now, few data are available concerning whether HLA-incompatible kidney transplantation after desensitization would benefit patients with ERSD. The desensitization strategy using the combination of PP, low doses of intravenous immunoglobulin, and rituximab at our center resulted in a satisfactory clinical outcome.

    The number of end-stage renal disease (ESRD) patients with preformed antibodies waiting for a kidney transplant has been increasing lately. We conducted a nationwide study on the outcomes of kidney transplantation after desensitization in Korea. Six transplant centers have run desensitization programs. The patients who underwent living donor kidney transplantation after desensitization from 2002 to 2010 were retrospectively analyzed. A total of 86 cases were enrolled. Thirty-five of these were cases of re-transplantation (40.7 %). Indications of desensitization were positive complement-dependent cytotoxicity (CDC) cross-match responses (CDC(+), 36.0 %), positive flow-cytometric cross-match responses (FCX(+), 54.7 %), and positive donor-specific antibodies (DSA(+), 8.1 %). The desensitization protocols used pre-transplant plasmapheresis (95.3 %), intravenous immunoglobulin (62.8 %), and rituximab (67.4 %). Acute rejection occurred in 18 patients (20.9 %), graft failure occurred in 4 patients, and the 3-year graft survival rate was 93.8 %. The presence of DSA increased the acute rejection rate (P = 0.015) and decreased the 1-year post-transplant estimated glomerular filtration rate (P = 0.006). Although rejection-free survival rates did not differ significantly between the CDC(+) and FCX(+) groups, the 1-year estimated glomerular filtration rate was lower in the CDC(+) group (P = 0.010). Infectious and significant bleeding complications occurred in 15.5 % and 4.7 % of cases, respectively. Kidney transplantation after desensitization had good graft outcomes and tolerable complications in Korea, and therefore, this therapy can be recommended for sensitized ESRD patients.

    Pre-existing humoral barriers challenge the transplantation of living donor kidneys (LDK) into highly sensitized ABO- and human leukocyte antigen (HLA)-incompatible recipients. Conditioning these LDK recipients' immune systems is required before they undergo transplantation. We hypothesized that medical desensitization would yield higher post-transplantation rates of infection. We conducted a study in which matched controls consisting of non-desensitized (NDS) LDK recipients were compared with desensitized (DS) receipients. Pre-transplantation desensitization included treatment with rituximab and mycophenolate mofetil followed by intravenous immunoglobulin (IVIg) and plasmapheresis. All participants in the study underwent induction therapy and maintenance immunosuppression. Primary outcomes included infection (opportunistic, local, systemic) within 12 mo after transplantation. Twenty-five patients underwent desensitization and LDK transplantation. Graft survival in the DS and NDS groups of patients was 96% and 98%, respectively. The mean 3- and 12-mo serum creatinine concentrations in the DS and NDS groups were 1.1±0.2 mg/dL and 1.2±0.3 mg/dL and 0.95±0.4 mg/dL and 0.73±0.8 mg/dL (p=0.3 and p=0.01), respectively. Thirty-six percent of the patients in the DS group had one or more infections, vs. 28% of those in the NDS group (p=0.1). No difference was observed in the frequency of opportunistic or systemic infections in the two groups. Local infections were statistically significantly more frequent in the DS group (60% vs. 30%, respectively; p=0.02). Pre-operative desensitization in highly sensitized LDK recipients is followed by a similar incidence of opportunistic and systemic infections as in NDS patients. Local infections were significantly more frequent in the DS than in the NDS patients in the study. With careful monitoring of infectious complications, pre-transplant desensitization permits LDK transplantation into highly sensitized patients.

    Full Text Available Toxic epidermal necrolysis (TEN is a severe adverse drug reaction characterized by necrosis of the epidermis. Its incidence is approximately 1 per million a year and average mortality rate is high at 25–50%. TEN has a flu-like prodrome, followed by atypical, targetoid erythematous or purpuric macules on the skin. These macules coalesce to form flaccid blisters that slough off as areas of epidermal necrosis. Drugs such as allopurinol, sulfonamides, and carbamazepine are the most common causes. The human leukocyte antigen (HLA-B*15:02 in Asians being administered carbamazepine and the HLA-B*58:01 antigen in patients of all ethnicities being administered allopurinol are known to be high-risk factors. Rapid diagnosis, discontinuation of the causative drug, and supportive treatment are essential for better prognosis and improvement of sequelae. Till now, systemic corticosteroids and intravenous immunoglobulins have been used as the most common active interventions; however, no gold standard has been established. In Japan, physicians follow a unique diagnostic criteria and treatment guideline to improve the diagnosis rate and streamline treatments. This may be a contributing factor for the lower mortality rate (14.3%. The efficacy of systemic corticosteroids, immunoglobulins, and plasmapheresis may have been beneficial as well. In Japan, TEN is defined as an epidermal detachment of over 10% of the body surface area (BSA, while the globally accepted definition established by Bastuji-Garin describes it as an epidermal detachment of over 30% of the BSA. In Japanese individuals, HLA-A*02:06, HLA-A*02:07, HLA-A*31:01 and HLA-B*51:01 may be linked to higher risks of TEN.

    Full Text Available Acute glomerulonephritis due to anti-glomerular basement membrane (anti-GBM antibody disease is rare, estimated to occur in fewer than one case per million population and accounts for less than 20% of rapidly progressive glomerulonephritis. The prevalence among patients evaluated for potential glomerular disease is lower. It accounts for fewer than 3% of all kidney biopsies done with crescentic glomerulonephritis. Cases of anti-GBM disease occurring in a cluster have rarely been reported. All biopsy proven anti-GBM disease cases were collected from January 2015 to March 2015 at our Institute. All cases were analyzed for demographic and clinical profile, pathological findings, treatment received and for any common environmental antigenic source. A total of 11 new biopsy proven anti-GBM cases were seen within a span of three months. Age group varied from 17–80 years. Seven were males and four were females. All were dialysis dependent at presentation. Seven had active cellular crescents, and four had fibrocellular. Only one patient was a smoker and none had a history of exposure to any forms of hydrocarbons. The peak seen from January 2015 to March 2015 does not correlate with any of seasonal occurrence of infections in southern India. Although there was clustering of cases to southern territories of Karnataka state, no common etiological agents could be identified. No patient had any previous urological surgeries. All patients received methylprednisolone with plasmapheresis 5–7 sessions and cyclophosphamide. All 11 patients were dialysis dependent at the end of three months. We conclude anti-GBM disease cannot be regarded as a rare cause of renal failure and lung hemorrhage. The occurrence of such epidemic within a short period suggests a possible unidentified environmental factor like infection or occupational agents as inciting agents. Identification of such inciting agents could help us in instituting appropriate preventing measures.

    A 74-year-old gentleman was admitted to the regional neurosciences center with encephalopathy, myokymia, and dysautonomia. Chest imaging had previously identified an incidental mass in the anterior mediastinum, consistent with a primary thymic tumor. Antivoltage-gated potassium channel (anti-VGKC) antibodies were positive (titer 1273 pmol/L) and he was hypokalemic. Electromyogram and nerve conduction studies were in keeping with peripheral nerve hyperexcitability syndrome, and an electroencephalogram was consistent with encephalopathy. A diagnosis of Morvan syndrome was made, for which he was initially treated with high-dose steroids, followed by a 5-day course of intravenous immunoglobulin (IVIG) therapy. He also underwent thymectomy, followed by a postexcision flare of his symptoms requiring intensive care management. Further steroids, plasmapheresis, and IVIG achieved stabilization of his clinical condition, enabling transfer for inpatient neurorehabilitation. He was commenced on azathioprine and a prolonged oral steroid taper. A subsequent presumed incipient relapse responded well to further IVIG treatment. This case report documents a thymoma-associated presentation of anti-VGKC-positive Morvan syndrome supplemented by patient and carer narrative and video, both of which provide valuable further insights into this rare disorder. There are a limited number of publications surrounding this rare condition available in the English literature. This, combined with the heterogenous presentation, association with underlying malignancy, response to treatment, and prognosis, provides a diagnostic challenge. However, the association with anti-VGKC antibody-associated complexes and 2 recent case series have provided some scope for both accurate diagnosis and management. PMID:26740856

    Full Text Available Throughout the past years we stepwise modified our immunosuppressive treatment regimen for patients with antibody-mediated rejection (ABMR. Here, we describe three consecutive groups treated with different regimens. From 2005 until 2008, we treated all patients with biopsy-proven ABMR with rituximab (500 mg, low-dose (30 g intravenous immunoglobulins (IVIG, and plasmapheresis (PPH, 6x (group RLP, n=12. Between 2009 and June 2010, patients received bortezomib (1.3 mg/m2, 4x together with low-dose IVIG and PPH (group BLP, n=11. In July 2010, we increased the IVIG dose and treated all subsequent patients with bortezomib, high-dose IVIG (1.5 g/kg, and PPH (group BHP, n=11. Graft survival at three years after treatment was 73% in group BHP as compared to 45% in group BLP and 25% in group RLP. At six months after treatment median serum creatinine was 2.1 mg/dL, 2.9 mg/dL, and 4.2 mg/dL in groups BHP, BLP, and RLP, respectively (p=0.02. Following treatment, a significant decrease of donor-specific HLA antibody (DSA mean fluorescence intensity from 8467±6876 to 5221±4711 (p=0.01 was observed in group BHP, but not in the other groups. Our results indicate that graft survival, graft function, and DSA levels could be improved along with stepwise modifications to our treatment regimen, that is, the introduction of bortezomib and high-dose IVIG treatment.

    The iron overload disorder hereditary haemochromatosis is most commonly caused by HFE p.Cys282Tyr homozygosity. In the absence of results from any randomised trials, current evidence is insufficient to determine whether individuals with hereditary haemochromatosis and moderately elevated serum ferritin, should undergo iron reduction treatment. This trial aimed to establish whether serum ferritin normalisation in this population improved symptoms and surrogate biomarkers. This study was a multicentre, participant-blinded, randomised controlled trial done at three centres in Australia. We enrolled people who were homozygous for HFE p.Cys282Tyr, aged between 18 and 70 years, with moderately elevated serum ferritin, defined as 300-1000 μg/L, and raised transferrin saturation. Participants were randomly assigned, via a computer-generated random number, to undergo either iron reduction by erythrocytapheresis (treatment group) or sham treatment by plasmapheresis (control group). Randomisation was stratified by baseline serum ferritin (cognitive subcomponent (-3·6, -5·9 to -1·3, p=0·0030), but not in the physical (-1·90 -4·5 to 0·63, p=0·14) and psychosocial (-0·54, -1·2 to 0·11, p=0·10) subcomponents. No serious adverse events occurred in either group. One participant in the control group had a vasovagal event and 17 participants (14 in the treatment group and three in the control group) had transient symptoms assessed as related to hypovolaemia. Mild citrate reactions were more common in the treatment group (32 events [25%] in 129 procedures) compared with the control group (one event [1%] in 93 procedures). To our knowledge, this study is the first to objectively assess the consequences of iron removal in individuals with hereditary haemochromatosis and moderately elevated serum ferritin. Our results suggest that serum ferritin normalisation by iron depletion could be of benefit for all individuals with hereditary haemochromatosis and elevated serum

    Currently, there is an extensive but highly inconsistent body of literature regarding donor adverse events (AEs) in haemapheresis. As the reports diverge with respect to types and grading of AEs, apheresis procedures and machines, the range of haemapheresis-related AEs varies widely from about 0.03% to 6.6%. The German Society for Transfusion Medicine and Immunohaematology (DGTI) formed a 'Haemapheresis Vigilance Working Party' (Arbeitsgemeinschaft Hämapheresevigilanz; AGHV) to create an on-line registry for comprehensive and comparable AE assessment with all available apheresis devices in all types of preparative haemapheresis: plasmapheresis (PLS), plateletpheresis (PLT), red blood cell apheresis, all kind of leukaphereses (autologous/allogeneic blood stem cell apheresis, granulocyte apheresis, lymphocyte/monocyte apheresis) and all possible types of multi-component apheresis. To ensure the comparability of the data, the AGHV adopted the 'Standard for Surveillance of Complications Related to Blood Donation' from the International Society for Blood Transfusion in cooperation with the International Haemovigilance Network (IHN) and the American Association of Blood Banks for AE acquisition and automated evaluation. The registry is embedded in a prospective observational multi-centre study with a study period of 7 years. A preliminary evaluation encompassed the time period from January, 2012 to December, 2015. During this time, the system proved to be safe and stable. Out of approximately 345,000 haemaphereses 16,477 AEs were reported (4.9%) from 20 participating centres. The majority of AEs occurred in PLSs (63%), followed by PLT (34.5%) and SC (2.2%). Blood access injuries (BAI) accounted for about 55% of the supplied AEs, whereas citrate toxicity symptoms, vasovagal reactions and technical events (e.g. disposable leakages, software failures) rather equally affected haemaphereses at 8-15%. Out of 12,348 finalized AEs, 8,759 (70.1%) were associated with a procedure

With currently available immune modulation protocols and immunosuppressive therapy, excellent short- and long-term patient and graft survival rates have been achieved even in those with high anti-A/B antibody titers before plasmapheresis or immunoadsorption. Nonetheless, acute infection with an organism possessing surface markers analogous to blood group antigens such as carbohydrate structures on

Renal replacement therapy (more often hemodialysis) should be started in patients with severe AKI and end stage renal disease (ESRD). High flux or high cut-off membrane are recommended because routine hemodialysis could not remove the serum free light chain (sFLC) effectively. Plasmapheresis (PE) is recommended for patients with hyperviscosity syndrome or cast nephropathy presented with AKI, which may help to increase the dialysis-independency.

    Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening mucocutaneous adverse drug reactions with a high morbidity and mortality that require immediate medical care. The various immunomodulatory treatments include systemic corticosteroids, cyclosporine, intravenous immunoglobulin, cyclophosphamide, plasmapheresis and tumor necrosis factor-α inhibitors. The ideal therapy of Stevens-Johnson syndrome/toxic epidermal necrolysis still remains a matter of debate as there are only a limited number of studies of good quality comparing the usefulness of different specific treatments. The aim of this article is to comprehensively review the published medical literature and frame management guidelines suitable in the Indian perspective. The Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) assigned the task of preparing these guidelines to its special interest group on cutaneous adverse drug reactions. The group performed a comprehensive English language literature search for management options in Stevens-Johnson syndrome/toxic epidermal necrolysis across multiple databases (PubMed, EMBASE, MEDLINE and Cochrane) for keywords (alone and in combination) and MeSH items such as "guidelines," "Stevens-Johnson syndrome," "toxic epidermal necrolysis," "corticosteroids," "intravenous immunoglobulin," "cyclosporine" and "management." The available evidence was evaluated using the strength of recommendation taxonomy and graded using a three-point scale. A draft of clinical recommendations was developed on the best available evidence which was also scrutinized and critically evaluated by the IADVL Academy of Dermatology. Based on the inputs received, this final consensus statement was prepared. A total of 104 articles (meta-analyses, prospective and retrospective studies, reviews [including chapters in books], previous guidelines [including Indian guidelines of 2006] and case series) were critically evaluated and the evidence

    Individuals engaged in the fields of artificial kidney and artificial heart have often mistakenly stated that "the era of artificial organs is over; regenerative medicine is the future." Contrarily, we do not believe artificial organs and regenerative medicine are different medical technologies. As a matter of fact, artificial organs developed during the last 50 years have been used as a bridge to regeneration. The only difference between regenerative medicine and artificial organs is that artificial organs for the bridge to regeneration promote tissue regeneration in situ, instead of outside the body (for example, vascular prostheses, neuroprostheses, bladder substitutes, skin prostheses, bone prostheses, cartilage prostheses, ligament prostheses, etc.). All of these artificial organs are successful because tissue regeneration over a man-made prosthesis is established inside the patient's body (artificial organs to support regeneration). Another usage of the group of artificial organs for the bridge to regeneration is to sustain the functions of the patient's diseased organs during the regeneration process of the body's healthy tissues and/or organs. This particular group includes artificial kidney, hepatic assist, respiratory assist, and circulatory assist. Proof of regeneration of these healthy tissues and/or organs is demonstrated in the short-term recovery of end-stage organ failure patients (artificial organs for bridge to regeneration). A third group of artificial organs for the bridge to regeneration accelerates the regenerating process of the patient's healthy tissues and organs. This group includes neurostimulators, artificial blood (red cells) blood oxygenators, and plasmapheresis devices, including hemodiafiltrators. So-called "therapeutic artificial organs" fall into this category (artificial organs to accelerate regeneration). Thus, almost all of today's artificial organs are useful in the bridge to regeneration of healthy natural tissues and organs

    Full Text Available In spite of success in treatment and diagnostics attained last years the problem of an acute pneumonia remains actual, this fact is caused by the growing rate of prolonged clinical course and unfavorable clinical outcomes. The growth of antibiotic resistance of microflora is a substantial problem. In addition even the most vigorous modern antibacterial preparations are not effective without an adequate surgical sanitation of the nidus of infection.The aim of the work is to improve the therapy of destructive pneumonia in children that need an intensive care.Methods. 12 patients 9 month – 12 years old who underwent the treatment of heavy community-acquired pneumonia were under observation. There was carried out an X-ray examination at admission and in dynamics, microbiological examination of lavages from the respiratory tract, pleural exudate and blood, determination of laboratory indexes of intoxication (by Kalf-Kalif, Dashtayants, Lubimova and the level of the middle molecules. The statistical analysis was done using the program package "Microsoft Excel" and "StatSoft 6".Results. In the course of microbiological examination it was demonstrated the prevalence of gram-negative flora and its associations with gram-positive one, the purely gram-positive flora was detected only in 25 % of children. So there was proved an inefficiency of antibiotics that effect mainly on the gram-positive microorganisms. In addition the cephalosporins of the third generation were found insufficiently effective. Such preparations as carbapenems or protected penicillins were chosen in vitro and according to its clinical efficiency. Plasmapheresis and bronchoscopy are useful in the complex therapy. Thoracoscopy must be carried out if the conservative treatment is not effectiveConclusions. At present the gram-negative flora and its associations with gram-positive one prevails in etiological structure of the heavy community-acquired pneumonias that must be taken into

    Despite the introduction of plasmapheresis and immunoglobulin therapy, many patients with Guillain-Barré syndrome still have an incomplete recovery. Evidence from pathogenesis studies suggests the involvement of complement-mediated peripheral nerve damage. We aimed to investigate the safety and efficacy of eculizumab, a humanised monoclonal antibody against the complement protein C5, in patients with severe Guillain-Barré syndrome. This study was a 24 week, multicentre, double-blind, placebo-controlled, randomised phase 2 trial done at 13 hospitals in Japan. Eligible patients with Guillain-Barré syndrome were aged 18 years or older and could not walk independently (Guillain-Barré syndrome functional grade 3-5). Patients were randomly assigned (2:1) to receive 4 weeks of intravenous immunoglobulin plus either eculizumab (900 mg) or placebo; randomisation was done via a computer-generated process and web response system with minimisation for functional grade and age. The study had a parallel non-comparative single-arm outcome measure. The primary outcomes were efficacy (the proportion of patients with restored ability to walk independently [functional grade ≤2] at week 4) in the eculizumab group and safety in the full analysis set. For the efficacy endpoint, we predefined a response rate threshold of the lower 90% CI boundary exceeding 50%. This trial is registered with ClinicalTrials.gov, number, NCT02493725. Between Aug 10, 2015, and April 21, 2016, 34 patients were assigned to receive either eculizumab (n=23) or placebo (n=11). At week 4, the proportion of the patients able to walk independently (functional grade ≤2) was 61% (90% CI 42-78; n=14) in the eculizumab group, and 45% (20-73; n=5) in the placebo group. Adverse events occurred in all 34 patients. Three patients had serious adverse events: two in the eculizumab group (anaphylaxis in one patient and intracranial haemorrhage and abscess in another patient) and one in the placebo group (depression

    Full Text Available A retrospective study of 42 cases of acute flaccid paralysis (AFP in children aged between 7 months and 15 years, registered at the Municipal Clinical Hospital №1 throughout a 7 year period (2007—2014, was performed to investigate the features of pediatric Guillian-Barre Syndrome (GBS. GBS has shown to be the most common cause of AFP in children, with prevalence of 74% of all 31 cases. Clinical manifestations, functional status, laboratory and electrodiagnostic data were evaluated in group of 31 children in order to highlight particular features of childhood GBS in Russia. The highest frequency of GBS was observed in children aged between 1 to 3 with the median 6 [3; 11] years. Boys with GBS outnumbered girls by a 2,1:1 ratio. No seasonal dependence has been observed, with children equally suffering from this disease without a seasonal pattern throughout the year. According to the electrophysiological and clinical data, 24 children were diagnosed with acute inflammatory demyelinating polyradiculoneuropathy (AIDP (77%, 5 with acute motor axonal neuropathy (AMAN (16% and 2 with аcute motor-sensory axonal neuropathy (AMSAN in a total of cases (7%. Several exclusive features of GBS in children for Russia were discovered. The most common initial symptom was limb pain, with the impartial sensory disturbance found only in 13% of the patients observed, 10% of which were paresthesias and the remaining 3% belonging to hypostesias. Children reached the nadir state rapidly, the median time from onset to nadir was 9.5 [6,25; 12,5] days. Cranial nerve dysfunction at nadir was observed in a greater percentage of patients (51% compared to that of 23% cases at the onset, with the facial palsy increasing from 10 to 32% and the bulbar palsy from 12 to 19%. The patients were given intravenous immunoglobulin in various doses: from 0.2 to 1.75 mg/kg per course (0.5 [0.5; 0.8] g/kg and/or plasmapheresis with a median volume of 93 [81; 100] ml/kg per

    Extracorporeal membrane oxygenation is a resource-intensive mode of life-support potentially applicable when conventional therapies fail. Given the initial success of extracorporeal membrane oxygenation to support neonates and infants in the 1980s, indications have expanded to include adolescents, adults, and selected moribund patients during cardiopulmonary resuscitation. This single-institution analysis was conducted to evaluate programmatic growth, outcomes, and risk for death despite extracorporeal membrane oxygenation across all ages and diseases. Beginning in 1989, we registered prospectively all extracorporeal membrane oxygenation patient data with the Extracorporeal Life Support Organization. We queried this registry for our institution-specific data to compare the parameter of "discharge alive" between age groups (neonatal, pediatric, adult), disease groups (respiratory, cardiac, cardiopulmonary resuscitation), and modes of extracorporeal membrane oxygenation (veno-venous; veno-arterial). Extracorporeal membrane oxygenation-specific complications (mechanical, hemorrhagic, neurologic, renal, cardiovascular, pulmonary, infectious, metabolic) were analyzed similarly. Descriptive statistics, Kaplan-Meier, and linear regression analyses were conducted. After 1,052 extracorporeal membrane oxygenation runs, indications have expanded to include adults, to supplement cardiopulmonary resuscitation, to support hemodialysis in neonates and plasmapheresis in children, and to bridge all age patients to heart and lung transplant. Overall survival to discharge was 52% and was better for respiratory diseases (P < .001). Probability of individual survival decreased to <50% if pre-extracorporeal membrane oxygenation mechanical ventilation exceeded respectively 123 hours for cardiac, 166 hours for cardiopulmonary resuscitation, and 183 hours for respiratory diseases (P = .013). Complications occurred most commonly among cardiac and cardiopulmonary resuscitation runs

    and co-trimoxazole along with plasmapheresis. Four weeks after treatment, the antibody titer came down to 1:320. Melioidosis antibody was absent in the baby. This case was challenging as it was an atypical presentation of melioidosis during postpartum leading to a diagnostic conundrum. This highlights the need to look into the effect of pregnancy and postpartum as added risk factors. High index of suspicion is necessary to avoid diagnostic delays.

    Full Text Available There are few papers devoted to geriatric Guillain-Barré (GBS and many related issues remain unanswered. OBJECTIVE: To describe clinical, electrophysiological and therapeutic features in this age. METHOD: Clinico-epidemiological data and therapy of GBS patients older than 60 years were reviewed. Hughes scores were used to quantify neurological deficit and define outcome. RESULTS: Among 18 patients (mean age 64.8 years, 9 had evident prodrome and 80% noticed initially sensory-motor deficit. Demyelinating GBS was found in 8 and axonal in 6 subjects. There was one Miller-Fisher and 3 unclassified cases. Plasmapheresis (PFX was single therapy in 12 patients and intravenous immunoglobulin (IVIg in 2. Disability scores just before therapy were similar in both groups, so as short and long term outcome. CONCLUSION: Axonal GBS seems to be more frequent in the elderly and this may have prognostic implications. PFX and IVIg were suitable options, but complications were noticed with PFX. Prospective studies are needed to better understand and manage GBS in the elderly.Publicações sobre a síndrome de Guillain-Barré (SGB no idoso são escassas e várias questões sobre o tema estão abertas.

A escala de Hughes foi usada para quantificar os déficits iniciais e finais. RESULTADOS: No total de 18 pacientes (média de idade 64,8 anos, 50% tiveram pródromo e 80% tiveram déficit sensitivo-motor no início. SGB desmielinizante foi encontrada em 8 pacientes, axonal em 6 e uma síndrome de Miller-Fisher. Três casos não puderam ser classificados. Plasmaférese (PFX foi empregada isoladamente em 12 pacientes e imunoglobulina endovenosa (IVIg em 2.

    Therapeutic plasmapheresis allows the extracorporeal removal of plasmatic lipoproteins (Lipid-apheresis) (LA). It can be non selective (non specific), semi - selective or selective low density lipoprotein-lipoprotein(a) (specific [LDL- Lp(a)] apheresis) (Lipoprotein apheresis, LDLa). The LDL removal rate is a perfect parameter to assess the system efficiency. Plasma-Exchange (PEX) cannot be considered either specific nor, selective. In PEX the whole blood is separated into plasma and its corpuscular components usually through centrifugation or rather filtration. The corpuscular components mixed with albumin solution plus saline (NaCl 0.9%) solution at 20%-25%, are then reinfused to the patient, to substitute the plasma formerly removed. PEX eliminates atherogenic lipoproteins, but also other essential plasma proteins, such as albumin, immunoglobulins, and hemocoagulatory mediators. Cascade filtration (CF) is a method based on plasma separation and removal of plasma proteins through double filtration. During the CF two hollow-fiber filters with pores of different diameter are used to eliminate the plasma components of different weight and molecular diameter. A CF system uses a first polypropylene filter with 0.55 µm diameter pores and a second one of diacetate of cellulose with 0.02 µm pores. The first filter separates the whole blood, and the plasma is then perfused through a second filter which allows the recovery of molecules with a diameter lower than 0.02 µm, and the removal of molecules larger in diameter as apoB100-containing lipoproteins. Since both albumin and immunoglobulins are not removed, or to a negligible extent, plasma-expanders, substitution fluids, and in particular albumin, as occurs in PEX are not needed. CF however, is characterized by lower selectivity since removes also high density lipoprotein (HDL) particles which have an antiatherogenic activity. In the 80's, a variation of Lipid-apheresis has been developed which allows the LDL

AHA treatment includes the control of hemorrhagic manifestations and the suppression of antibody production. The recombinant factor VIIIa (rVIIIaF concentration and the prothrombin-complex concentrations (PCC are considered like the first-line antihemorrhagic treatment. As alternative therapy in some cases the FCIII concentration, the plasmapheresis and extracorporeal immuno-adsorption may be used. The prednisone alone or associated with cyclophosphamide is the firs-line immunosuppressive treatment. In refractory patients it may be administered as a second-line therapy, the Rituximab (anti-CD20. With the use of Azathioprine, Cyclosporine, Vincristine and the Mycophenolate mofetil variable results have been achieved.

    Buenos Aires area, Argentina. Data was revised in the charts from March 1997 to March 2003 and 62 patients were included in the study. During the second half of pregnancy or immediate puerperal period, diagnostic criteria were defined on the basis of preeclampsia and the following laboratory abnormalities: platelet count nadir 70 UI/l, and serum lactic dehydrogenase >600 UI/l, total bilirubin >1.2 mg/dl and/or periferical blood smear with hemolysis. The mean maternal age was 28 ± 8 years; parity 2.7 ± 2.3; gestational age 33 ± 4 weeks. According to platelet count, 23 cases were identified to class 1, 29 to class 2 and the rest to Martin's class 3. There were 16 eclamptic patients. The platelet count was 67 604 ± 31 535/mm3; alanine aminotransferase 271 ± 297 UI/l; aspartate aminotransferase 209 ± 178 UI/l; serum lactic dehydrogenase 1 444 ± 1 295 UI/l; serum creatininine levels 1.1 ± 0.8 mg/dl. Forty-one patients had diverse degree of renal function damage, renal dialysis and plasmapheresis was required in one female. Respiratory failure due to pulmonary edema was observed in four patients. All obstetric patients survived. There were four perinatal deaths. In our population sample, low rate of life-threatening maternal complications and low perinatal mortality were observed.

    Full Text Available Myasthenic crisis (MC is a life-threatening complication of myasthenia gravis (MG with a high mortality rate. The aim of our study was to review the different therapeutics approaches in the treatment of MC and their impact in the final outcome. We reviewed the medical files of patients diagnosed with MG admitted between February 1993 and October 1997, who developed MC. Sex, mean age, disease's duration, functional scale, symptoms preceding the crisis, crisis therapy in each set and mortality were then analysed. There were 24 patients who developed MC, 21 females and 3 males, with 1 neonatal, 1 congenital sporadic, 17 juvenile/adult, 3 over 50 years and 2 with thymoma. Dysphagia, dysphonia and dysartria were the most common symptoms preceding the crisis. A precipitating factor was elicited in 8 cases and the most common was infection (upper airway infection, urinary tract infection and pneumonia. 16 patients needed a nasogastric tube and 9 had a tracheostomy performed. 24 patients used anticholinesterase drugs, 21 prednisone, 7 immunosuppressive agents, 5 plasmapheresis, 3 human hyperimune gamma immunoglobulin and 12 had thymectomy. A good response was obtained in 13, satisfactory in 7 and there were 4 deaths. We concluded that in spite of all the therapeutics options, there were non statistically significant differences in the outcome of patients that underwent thymectomy and those who did not.A crise miastênica (CM é uma complicação preocupante da miastenia grave (MG que apresenta altos índices de mortalidade.

    administración endovenosa de gamma globulina.Juvenile myasthenia gravis is a chronic autoimmune disorder which occurs when serum antibodies combine with nicotinic acetylcholine receptors at the muscle membrane of the motor endplate imparing the neuromuscular transmission. It results in early muscle fatigability with progression to a complete paralysis during repetitive muscle contraction (movements or steady muscle contraction (postures, and less common persistent paralysis at rest. The cranial nerves, mainly the one innervating the extraoccular and palpebral levator, are the most susceptible to permanent weakness and paralysis at rest. Initial clinical presentations are generalized, ocular and respiratory forms. The diagnosis is suspected through medical history of abnormal fatigability and corroborated by physical examination, repetitive nerve stimulation of an affected but not complete paralyzed muscle, correction of fatigability by the intravenous administration of acetylcholine esterase inhibitors, and by the presence of serum acetylcholine receptors antibodies (ACRA. The long term treatment is symptomatic (acetylcholine inhibitors and etiopathogenic (immunosupresor drugs, plasmapheresis, intravenous gamma globulin and thymectomy. Spontaneous or post symptomatic and etiopathogenic treatment remissions occur from 1 to 10 years. Fatality is rare but children are at high risk during myasthenia crisis.

    . AIDP is associated in 30-50% of cases with cranial nerve involvement, which is not observed in AMAN. MFS is characterized by ataxia, ophthalmoplegia and areflexia, but it may also present cranial nerve dysfunction. Recent data on the pathology and pathophysiology of GBS emphasize the important role of Campylobacter jejuni infection in generating anti-ganglioside antibodies (GM1 in AIDP, GQ1b in MFS and GD1a in AMAN, which damage myelin in AIDP and MFS and axons in AMAN. The differential diagnosis must rule out other disorders of the central nervous system (encephalitis, encephalomyelitis, myelitis, myasthenic syndromes, toxic neuropathies induced by heavy meals, drugs, chemical substances or animal toxins, and myopathic conditions, especially acute benign infectious myositis and neuromyopathy of the intensive care unit patient. It is important the treatment with immune globulin, at a total dose of 2 grams per kilogram administered over 48 hours. Plasmapheresis can be equally effective. GBS has a good prognosis in children with a total recovery in 85% of cases. Rehabilitation is crucial to attain a more rapid and global improvement.

Of the 49 patients, a group of 6 children representative for individual disorders was selected. In those patients, the etiology of both endocrine disorders, epilepsy and neuropsychiatric disorders was suspected to be common, and the diagnosis was usually delayed. 1. Cranial irradiation and chemotherapy, encephalopathy associated with Hashimoto disease and some of the syndromes with the chromosomal and genetic background are the causes of non-structural CNS abnormalities and coincidence of endocrinopathies, epilepsy and psychoneurologic disorders. 2. MR/CT CNS imaging should be performed in any case of central neurological disorders, disorders of behavior, epilepsy or seizures, but also in patients with delayed psycho-motor development, delayed or accelerated growth and pubertal development. All of the above-mentioned manifestations may be symptoms of structural CNS abnormalities and their early treatment determines the child's future. 3. Excluding structural CNS abnormalities allows for forming suspicions associated with diseases resulting in non-structural disorders of the CNS function, predisposing to coincidence of endocrine and neurological disorders. 4. In the diagnosis of Hashimoto's encephalopathy, a decisive factor is exclusion of structural, infectious, traumatic and metabolic causes, intoxications, epilepsy and presence of neuropsychiatric symptoms in patients with high level of against TPO antibodies. In cases of steroids resistance, a good therapeutic effect may be achieved by plasmapheresis, Rituximab therapy and progestagene inhibition of the menstrual cycle.

    Many investigators have demonstrated the ability to treat hematologic malignancies with radiolabeled monoclonal antibodies targeting hematopoietic antigens such as anti-CD20 and anti-CD45. [1-5] Although the remission rates achieved with radioimmunotherapy (RIT) are relatively high, many patients subsequently relapse presumably due to suboptimal delivery of enough radiation to eradicate the malignancy. The dose-response of leukemia and lymphoma to radiation has been proven. Substantial amounts of radiation can be delivered by RIT if followed by hematopoietic cell transplantation to rescue the bone marrow from myeloablation.[ref] However, the maximum dose of RIT that can be used is still limited by toxicity to normal tissues affected by nonspecific delivery of radiation. Efforts to improve RIT focus on improving the therapeutic ratios of radiation in target versus non-target tissues by removing the fraction of radioisotope that fails to bind to target tissues and circulates freely in the bloodstream perfusing non-target tissues. Our group and others have explored several alternatives for removal of unbound circulating antibody. [refs] One such method, extracorporeal adsorption therapy (ECAT) consists of removing unbound antibody by a method similar to plasmapheresis after critical circulation time and distribution of antibody into target tissues have been achieved. Preclinical studies of ECAT in murine xenograft models demonstrated significant improvement in therapeutic ratios of radioactivity. Chen and colleagues demonstrated that a 2-hour ECAT procedure could remove 40 to 70% of the radioactivity from liver, lung and spleen. [ref] Although isotope concentration in the tumor was initially unaffected, a 50% decrease was noted approximately 36 hours after the procedure. This approach was also evaluated in a limited phase I pilot study of patients with refractory B-cell lymphoma. [ref] After radiographic confirmation of tumor localization of a test dose of anti-CD20

    Avascular bone necrosis is a relatively rare but significant complication in renal transplant recipients because it causes progressive pain and invalidity. It can be the consequence of the action of numerous causative factors, but it is mostly connected to corticosteroid treatment.The underlying pathophysiologic mechanism is a diminished blood flow to the bone leading to necrosis and bone destruction. During the past 25-years period, 570 renal transplantations and five combined kidney and pancreas transplantations were performed in our centre. A part of the patients was lost to follow-up due to the separation of Croatia from the former Republic of Yugoslavia. After transplantation, we revealed aseptic necrosis of the femoral head in five female patients. All patients had a history of treatment with pulse doses of corticosteroids. At transplantation the average age of the patients was 52.2 yrs (range 46 to 62 yrs), and dialytic treatment before transplantation lasted in average 9.2 yrs (range 2.5 to 21.2 yrs). The period between renal transplantation and the development of clinical signs of avascular bone necrosis lasted in average 1.2 yrs (range 0.3 to 2.3 yrs). We will demonstrate our 62-year old female patient with terminal renal failure caused by post-streptococcal glomerulonephritis, who was treated with peritoneal dialysis 2.5 years before renal transplantation. Twenty months before renal transplantation the patient received pulse doses of corticosteroids, together with immunoglobulins and plasmapheresis, for the treatment of an acute polyradiculoneuritis Guillaine Barré. After transplantation a standard immunosuppressive protocol was applied which included tacrolimus, mycophenolate mofetil, corticosteroids and induction with basiliximab. Four months after transplantation the patient started to feel pain in the right hip after longer standing, in addition to the earlier long-lasting problems caused by bilateral coxarthrosis. The pelvic radiograph showed

    hemodilution can be considered in selected patients with adequate preoperative hemoglobin to reduce post-CPB bleeding (Class IIa, Level A).The routine use of acute normovolemic hemodilution is not recommended (Class IIb, Level B). RECOMMENDATIONS FOR RETROGRADE AUTOLOGOUS PRIMING: Retrograde autologous priming is recommended as a blood conservation modality to reduce allogeneic blood transfusion for onpump cardiac surgery (Class I, Level A). RECOMMENDATIONS FOR CELL SALVAGE: Routine use of cell salvage is recommended in operations where an increased blood loss is expected (Class 1, Level A). Cell salvage should be used throughout the entire operation and not merely as a replacement for CPB cardiotomy suction (Class IIa, Level A). BIOCOMPATIBLE CPB CIRCUITS: The routine use of biocompatible coated CPB circuitry may be considered as part of a multimodal blood conservation program. However, the heterogeneity of surface-modified products, anticoagulation management, and CPB technique does not significantly impact surgical blood loss and transfusion needs (Class IIb,Level A). RECOMMENDATIONS FOR MINIATURIZED EXTRACORPOREAL CARDIOPULMONARY CIRCUIT VERSUS CONVENTIONAL EXTRACORPOREAL CARDIOPULMONARY CIRCUIT: Miniaturized extracorporeal cardiopulmonary circuit can be considered as a blood conservation technique to reduce allogeneic blood exposure (Class IIa, Level A); however, issues related to heparinization management and biocompatible coatings remain to be clarified. RECOMMENDATIONS FOR ULTRAFILTRATION (CONTINUOUS OR MODIFIED):h Ultrafiltration may be considered for blood conservation (Class IIb, Level A); however, the impact on clinically relevant outcomes remains unknown. RECOMMENDATIONS FOR PLATELET PLASMAPHERESIS:It is reasonable to recommend platelet plasmapheresis for blood management in cardiac surgery (Class IIa, Level A), although the impact on clinically relevant outcomes remains unknown. RECOMMENDATIONS FOR POINT-OF-CARE MONITORING:The evidence is too premature to

    by plasmapheresis from paid donors, carries a much higher risk of transmission of hepatitis B or C or HIV. Acquired autoimmune disease or AIDS, which is caused by HIV was once an incurable and fatal disease. However the anti-retro virus therapy, from the commencement of protease inhibitor based therapy in 1996, has increased the life expectancy of HIV patients. Nevertheless, adherence to highly active anti-retroviral therapy (HAART) medication by patients with hemophilia (66%-84%) is lower than that of patients with only HIV (98%) in Japan.Although the causes of low adherence of hemophilia therapy or HAART medication are considered to be associated with patient values, qualitative evidence of previous studies have not been synthesized We searched previous reviews and review protocols in the Cochrane Library, Joanna Briggs Institute Library (JBI), MEDLINE, CINAHL, PsycINFO, JBI COnNECT+ protocols. Regarding hemophilia or HIV, there were 11 systematic reviews, 7 protocols, and 128 other reviews. We excluded the reviews that were randomized controlled trials (RCTs) of treatment effects or therapies, and quantitative research of quality of life (QOL). We also excluded children as they are supervised by their parents to maintain high adherence. After the title and abstract review, 15 reviews remained and upon reading the full articles, one protocol and nine narrative reviews were identified.The systematic review protocol of Shaibu et al. investigated HIV positive adult patients on HAART focusing on the experience of HIV positive patients with patients' lifestyles and beliefs about HIV/AIDS and HAART effectiveness, and the role these play in adherence. However, the review differs from this one in terms of classification of HIV positive adults by the route of infection such as iatrogenic and sexually transmitted infection. Taking the deferent rate of adherence of HAART in Japan into consideration, we will focus on the experience of hemophilic patients with HIV.There were
