Neutropenia, usually defined as a blood neutrophil count <1·5 × 10 9 /l, is a common medical problem for children and adults. There are many causes for neutropenia, and at each stage in life the clinical pattern of causes and consequences differs significantly. I recommend utilizing the age of the child and clinical observations for the preliminary diagnosis and primary management. In premature infants, neutropenia is quite common and contributes to the risk of sepsis with necrotizing enterocolitis. At birth and for the first few months of life, neutropenia is often attributable to isoimmune or alloimmune mechanisms and predisposes to the risk of severe bacterial infections. Thereafter when a child is discovered to have neutropenia, often associated with relatively minor symptoms, it is usually attributed to autoimmune disorder or viral infection. The congenital neutropenia syndromes are usually recognized when there are recurrent infections, the neutropenia is severe and there are congenital anomalies suggesting a genetic disorder. This review focuses on the key clinical finding and laboratory tests for diagnosis with commentaries on treatment, particularly the use of granulocyte colony-stimulating factor to treat childhood neutropenia. © 2017 John Wiley & Sons Ltd.

Objectives Reports of an association between antineutrophil cytoplasmic antibodies (ANCA) and autoimmune neutropenia have rarely included cases of proven vasculitis. A case of ANCA-associated vasculitis (AAV) with recurrent neutropenia is described and relevant literature on the association between ANCA, neutropenia, and vasculitis is reviewed. Methods Longitudinal clinical assessments and laboratory findings are described in a patient with AAV and recurrent episodes of profound neutropenia from December 2008 – October 2010. A PubMed database search of the medical literature was performed for papers published from 1960 through October 2010 to identify all reported cases of ANCA and neutropenia. Results A 49 year-old man developed recurrent neutropenia, periodic fevers, arthritis, biopsy-proven cutaneous vasculitis, sensorineural hearing loss, epididymitis, and positive tests for ANCA with specificity for antibodies to both proteinase 3 and myeloperoxidase. Antineutrophil membrane antibodies were detected during an acute neutropenic phase and were not detectable in a post-recovery sample, whereas ANCA titers did not seem to correlate with neutropenia. An association between ANCA and neutropenia has been reported in 74 cases from 24 studies in the context of drug/toxin exposure, underlying autoimmune disease, or chronic neutropenia without underlying autoimmune disease. In these cases, the presence of atypical ANCA patterns and other antibodies were common; however, vasculitis was uncommon and when it occurred was usually limited to the skin and in cases of underlying toxin exposure. Conclusions ANCA is associated with autoimmune neutropenia, but systemic vasculitis rarely occurs in association with ANCA and neutropenia. The interaction between neutrophils and ANCA may provide insight into understanding both autoimmune neutropenia and AAV. PMID:21507463

Full Text Available A neutropenia febril (NF é uma complicação frequente e potencialmente fatal nos pacientes em tratamento quimioterápico. Entendemos hoje que a neutropenia febril é considerada uma emergência clínica e que a administração de antibióticos de amplo espectro diminui drasticamente a mortalidade. Estudos sugerem que a neutropenia febril compreende um grupo extremamente heterogêneo e que dados clínicos como febre domiciliar, ausência de hipotensão, ausência de desidratação, ausência de doença pulmonar obstrutiva crônica, ausência de outros sintomas, ausência de infecção fúngica prévia e idade Febrile neutropenia is a frequent and potentially fatal adverse event of chemotherapy. Nowadays, febrile neutropenia is considered an emergency and it is known that prompt infusion of antibiotics decreases mortality. Several studies demonstrated that febrile neutropenia is a heterogeneous group of diseases and that factors such as outpatient status, no hypotension, no dehydration, no chronic obstructive pulmonary disease, no symptoms, no previous fungal infection and age < 60 years are protective factors against serious complications as demonstrated by the Multinational Association for Supportive Care in Cancer (MASCC. These data show that outpatient treatment and early discharge is safer and much research has shown lower costs for outpatient treatment in low-risk patients with febrile neutropenia. The aim of this work is to review and discuss tools (in particular the MASCC index for safe screening of febrile neutropenia for outpatient treatment in addition to demonstrate results of research.

Full Text Available Abstract The term congenital neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, severe ( When neutropenia is detected, an attempt should be made to establish the etiology, distinguishing between acquired forms (the most frequent, including post viral neutropenia and auto immune neutropenia and congenital forms that may either be isolated or part of a complex genetic disease. Except for ethnic neutropenia, which is a frequent but mild congenital form, probably with polygenic inheritance, all other forms of congenital neutropenia are extremely rare and have monogenic inheritance, which may be X-linked or autosomal, recessive or dominant. About half the forms of congenital neutropenia with no extra-hematopoetic manifestations and normal adaptive immunity are due to neutrophil elastase (ELANE mutations. Some patients have severe permanent neutropenia and frequent infections early in life, while others have mild intermittent neutropenia. Congenital neutropenia may also be associated with a wide range of organ dysfunctions, as for example in Shwachman-Diamond syndrome (associated with pancreatic insufficiency and glycogen storage disease type Ib (associated with a glycogen storage syndrome. So far, the molecular bases of 12 neutropenic disorders have been identified. Treatment of severe chronic neutropenia should focus on prevention of infections. It includes antimicrobial prophylaxis, generally with trimethoprim-sulfamethoxazole, and also granulocyte-colony-stimulating factor (G-CSF. G-CSF has considerably improved these patients' outlook. It is usually well tolerated, but potential adverse effects include thrombocytopenia, glomerulonephritis, vasculitis and osteoporosis. Long-term treatment with G-CSF, especially at high doses, augments the spontaneous risk of leukemia in patients with congenital neutropenia.

Full Text Available Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

Full Text Available As dental practitioners, we often come across oral ulcerations of varied etiology. Among all the causes of oral ulcers, those due to neutropenia are significant. Neutropenia can occur in many systemic conditions and also in patients on long-term therapy of certain drugs like phenytoin. The diagnosis of neutropenia in time leads to early recognition of the cause of this fatal condition. Here, we report a case of a 50-year-old female patient who developed oral ulcerations secondary to phenytoin-induced neutropenia. Early diagnosis of the condition led to discontinuation of the offending drug and significant improvement in her blood picture and also prevented her from falling prey to many other systemic infections that neutropenia can cause.

Aggressive chemotherapy protocols result in neutropenia in approximately half of all patients receiving chemotherapy. Thus, neutropenia continues to be a significant and potentially life-threatening side effect of treatment, even with use of colony-stimulating factors. Families of patients with neutropenia often provide the primary healing environment because most chemotherapy protocols are managed on an outpatient basis. To learn about the family's experience of managing chemotherapy-induced neutropenia (CIN), a grounded-theory methodology was used to analyze data from seven families. The central theme revealed by these families was "turbulent waiting with intensified connections." This meant that when families had a sense of greater vulnerability in response to the waiting after diagnosis of CIN, they connected intensely with each other and healthcare providers. Families reported that connections with nurses became more significant when neutropenia interrupted chemotherapy. Families also developed family caring strategies to manage this period of waiting for the chemotherapy to resume. These strategies included family inquiry, family vigilance, and family balancing. Nurses need to be aware of approaches to support the family's ability to manage CIN. Interventions and approaches constructed from the perspective of a family-professional partnership will enhance the family cancer experience as well as ongoing family growth and function.

Full Text Available Abstract Background Benign neutropenia, i.e., neutropenia not associated with an increased risk of infection, may result in serious medical consequences when a 'standard' definition of neutropenia (absolute neutrophil count (ANC 9cells/L is universally applied to all races. The aims of this study were to determine the prevalence of benign neutropenia among healthy Arabs and evaluate its mode of inheritance. Methods ANCs were studied prospectively amongst a healthy indigenous population (n = 1032 from the United Arab Emirates undergoing a nation-wide sickle-cell and thalassemia screening program. The mean neutrophil count and the prevalence of benign neutropenia were compared by age, sex and amongst various tribes. Results The mean neutrophil count (× 109cells/L was 3.3 (range 0.95–7.6. Benign neutropenia was present in 110 (10.7% subjects of whom 24 (2.3% individuals had moderate neutropenia (ANC 0.5 – 1.0 × 109 cells/L. In the 22 tribe-family groups, the prevalence of benign neutropenia varied between 0% and 38%. Benign neutropenia showed no difference in the frequency amongst the sexes (p = 0.23 and it was independent of age (Spearman's rho = 0.05, p = 0.13. The age-related mean neutrophil count was the lowest in Arabs when compared with other ethnic groups (Blacks, Europeans and Mexicans. The inheritance of benign neutropenia was consistent with an autosomal dominant pattern; however, the diversity of observed phenotypes suggested the presence of more than one genetic variant for this trait. Conclusion Arabs have a high prevalence of benign neutropenia that may be inherited as an autosomal dominant trait.

Richardson, Danielle; Poirier, Valerie J; Matsuyama, Arata; Calvalido, Jerome

Thirty-seven dogs with histologically or cytologically confirmed malignant tumors treated with single-agent mitoxantrone at 5 mg/m 2 were evaluated in a retrospective study assessing the correlation between body weight and neutropenia associated with a single dose of mitoxantrone in dogs. Overall, eight dogs (21%) experienced grade 3 neutropenia and five dogs (14%) experienced grade 4 neutropenia on day 7 following mitoxantrone chemotherapy. Dogs ≤10 kg body weight were significantly more likely to develop grade 3 or 4 neutropenia (5.8 relative risk; 95% confidence interval, 2.6-12.9; P 10 kg. Dogs ≤15 kg body weight were significantly more likely to develop grade 3 or 4 neutropenia (8.1 relative risk; 95% confidence interval, 2.1-31.3; P 15 kg. Of the 13 patients who developed grade 3 or 4 neutropenia, 6 (46%) were hospitalized for clinical signs related to neutropenia. Based on the severity of neutropenia and the resulting hospitalization seen in dogs ≤10 kg, a dose reduction could be considered for the initial dose of mitoxantrone, and clinicians should be aware of the increased risk of neutropenia in patients 10.1 to ≤15 kg.

This study examined the incidence, outcome and risk factors of neutropenia in infants with hemolytic disease of the newborn (HDN). A retrospective chart review was performed on infants with HDN. Of 69 evaluable infants, 45% developed neutropenia. Only one infectious complication was recorded. In most instances the neutropenia resolved spontaneously, but in seven infants it persisted for a median of 397 days. Males were at higher risk for developing neutropenia, but severity of HDN, antibody specificity, or therapy were not significant risk factors. Neutropenia is a common feature of HDN, regardless of severity of disease, treatment received, or antibody specificity. Copyright © 2011 Wiley Periodicals, Inc.

Congenital neutropenia is a heterogeneous bone marrow failure syndrome characterized by a maturation arrest of myelopoesis at the promyelocyte/myelocyte stage. Cyclic neutropenia (CyN) and severe congenital neutropenia (SCN) are two main forms of congenital neutropenia. Genetic analysis has shown that heterozygous mutations in the ELANE gene encoding the neutrophil elastase are the major cause of these disorders. We investigated the prevalence of ELANE mutations in a group of 16 patients from 14 families with congenital neutropenia. Five patients had typical manifestations of CyN, and 11 patients had SCN. Seven different heterozygous ELANE mutations were found, including four novel mutations. Copyright © 2011 Wiley-Liss, Inc.

Febrile neutropenia in haematological malignancies

Full Text Available Fever is the principle sign of infection in neutropenic patient and frequently may be the only evidence of infection. The pattern of fever in neutropenia is non-specific and not pathognomonic of any type of infections or non-infectious process and can be suppressed by the antipyretic effects of drugs such as corticosteroids. Neutropenia, resulting from cytotoxic chemotherapy is the most common risk factor for severe infections in hematological malignancies. The duration of neutropenia also contributes significantly to the risk of serious infections. This risk is significantly greater a lower neutrophil counts, such that 100% patients with ANC < 100 cells/µl lasting 3 weeks or more develop documented infections. The prompt initiation of empirical antibiotics in febrile neutropenia has been the most important advance in the management of the immunocompromised host. The initial empirical antibiotic regimen started at presentation of the febrile episode frequently requires modifications especially in high-risk febrile neutropenia. Neutropenic patients who remain febrile despite 4-7 days of broad spectrum antibacterial therapy are at a high risk of invasive fungal infection. Empirical antifungal therapy with Amphotericin B in persistently febrile neutropenic patients and other high risk patients has shown to reduce the risk of invasive fungal infection by 50-80% and the risk of fungal infection related mortality by 23-45% in 1980′s. The IDSA has recommended that amphotericin B at 0.5-0.7 mg/kg/day be administered till marrow recovery. This approach is limited however by the adverse effects caused by drug infusion (fever, chills, myalgias, nausea, hypotension and bronchospasm. Lipid formulations which improve the therapeutic ratio of the traditional formulation are available. The safety and efficacy of these formulations is well established. These formulations have comparable efficacy and are less nephrotoxic than conventional amphotericin B

Full Text Available La neutropenia febril es una de las complicaciones más frecuentes y de mayor morbilidad y mortalidad en los pacientes hematológicos. Su documentación microbiológica es una herramienta invaluable para el manejo; sin embargo, la cambiante tendencia en etiología de la bacteriemia y el patrón de susceptibilidad antimicrobiana comprometen la tasa de respuesta a los esquemas de tratamiento empírico. Objetivo: Determinar la etiología de bacteriemia en pacientes con neoplasias hematológicas y neutropenia febril, su patrón de susceptibilidad antimicrobiana y el grado de resistencia vigente a los medicamentos comúnmente utilizados en esquemas empíricos de manejo. Material y métodos: Se revisaron datos microbiológicos de las historias clínicas de pacientes hematológicos, hospitalizados en el HNERM entre diciembre 2010 y marzo 2012; que habían presentado neutropenia febril y bacteriemia concurrente. La información se analizó con el paquete estadístico STATA v. 10 y se empleó estadística descriptiva. Resultados: La bacteriemia fue predominantemente por bacterias gram negativas (75,9% y post consolidación de LMA con Ara-C por gram positivas (63,6%. La mortalidad de pacientes post reinducción con bacteriemia fue 75% y se asoció a Klebsiella pneumoniae BLEE+ en 31,2%. Conclusiones: Gérmenes gram negativos fueron la etiología más frecuente de bacteriemia en la población estudiada, particularmente en pacientes que recibieron quimioterapia de reinducción, donde se vio la mayor frecuencia de bacteriemia con mayor resistencia y asociados a mayor mortalidad. Posterior a quimioterapia de consolidación con Citarabina en altas dosis para LMA, resultó más frecuente la bacteriemia a gram positivos. Carbapenems y Amoxicilina/Clavulánico mostraron considerable menor resistencia que cefalosporinas y fluoroquinolonas.

Full Text Available La prematuridad es una problemática que se encuentra en aumento a nivel mundial. En Argentina 8 de cada 100 bebés nacen antes de tiempo, de ahí la importancia de sensibilizar a la población sobre este tema. Para la logoterapia la motivación básica y propia del ser humano es su orientación fundamental hacia el sentido, es de- cir, el encontrar y descubrir un porqué y para qué. Tener en cuenta la dimensión existencial de la persona es una forma de acercarnos al problema. Por tal motivo el objetivo del trabajo que se in forma fue relacionar el sentido de vida develado por las madres de niños que se encuentran internados en Unidad de Cuidados Intensivos Neona- tales (UCIN debido a su nacimiento prematuro con dos factores; por un lado con la capacidad que ellas mismas refieren para informarse adecuadamente acerca de la situación de su hijo y por el otro, con su vinculación con situaciones límite vividas durante el embarazo. Se realizó un estudio experimental con 30 madres de niños prematuros que han pasado por una internación en UCIN en tres instituciones hospitalarias. Se construyó un instrumento con formato de entrevista semidirigida llamado Vivencia de Madres de Niños Nacidos Prematuramente. Los resultados demuestran que las madres con mayor capacidad para solicitar información sobre la situación de sus hijos son las que pudieron dar respuestas acerca de la pregunta sobre el sentido que esta situación les permitía descubrir. En un porcentaje menor pudieron relacionarse las respuestas con situaciones límites vividas con anterioridad.

Full Text Available Extracts from deer bones, called nok-gol in Korean, have long been used to invigorate Qi. While neutropenia is not well detected in normal physiological condition, it could be a cause of severe problems to develop diseases such as infectious and cancerous diseases. Thus, a prevention of neutropenia in normal physiology and pathophysiological states is important for maintaining Qi and preventing disease progress. In cell biological aspects, activated macrophages are known to prevent neutropenia. In this study, we demonstrate that water extract of deer bone (herein, NG prevents neutropenia by activating macrophages. In mouse neutropenia model system in vivo where ICR mice were treated with cyclophosphamide to immunosuppress, an oral administration of NG altered the number of blood cells including lymphocytes, neutrophils, basophils, and eosinophils. This in vivo effect of NG was relevant to that of granulocyte colony stimulating factor (G-CSF that was known to improve neutropenia. Our in vitro studies further showed that NG treatment increased intracellular reactive oxygen species (ROS and promoted macrophagic differentiation of mouse monocytic Raw264.7 cells in a dose-dependent manner. In addition, NG enhanced nitric oxide (NO synthesis and secretions of cytokines including IL-6 and TNF-α. Consistently, NG treatment induced phosphorylation of ERK, JNK, IKK, IκBα, and NF-κB in Raw264.7 cells. Thus, our data suggest that NG is helpful for alleviating neutropenia.

Re-challenge with Etanercept in patients with Etanercept-induced Neutropenia.

TNF blockers have rarely been associated with haematological complications; however, there are scattered case reports of marked neutropenia with their use and necessitating in their withdrawal. We would like to report a series of five patients who developed neutropenia with etanercept use; however, all these patients were re-challenged with etanercept with a mean follow up of 30 months. These patients developed neutropenia within 2 months of starting etanercept. Two patients were eventually taken off etanercept; one of them needed switching to a different form of TNF blockers, and the second patient is in clinical remission with low-dose corticosteroids. All our patients continued to have mild-moderate degree of neutropenia; however, they are being monitored very closely and they are enjoying complete disease remission. It was interesting to note that none of our patients had increased infections during the re-challenge phase, even though they had grade 2 to grade 4 neutropenia. We have re-challenged these patients without any clinical complications, revealing that patients with mild to moderate neutropenia can be safely exposed to TNF blockers as long as they are monitored with regular cell count checks. Although largely noted to be clinically insignificant in our patient series, the potential of drug-induced neutropenia in causing higher rate of infections do exist. Careful clinical and hematologic monitoring is the best way to recognize this adverse event.

The introduction of granulocyte colony-stimulating factors (G-CSFs in clinical practice has remarkably reduced the duration and severity of neutropenia, as well as the incidence of FN, thus allowing the administration of chemotherapeutic agents at the optimal dose and time with lower risk. The current scenario of G-CSFs in Europe includes filgrastim, lenograstim, some G-CSF biosimilars, and pegfilgrastim. Recently, a novel long-acting G-CSF, lipegfilgrastim, became available. Lipegfilgrastim is a glycopegylated G-CSF, alternative to pegfilgrastim, and has shown in randomized trials, to be equivalent to pegfilgrastim in reducing the incidence of severe neutropenia and FN in patients with breast cancer receiving chemotherapy, with a similar safety profile. Furthermore, lipegfilgrastim was more effective than the placebo in reducing the incidence of severe neutropenia, its duration, and time to absolute neutrophil count recovery, in patients with non-small cell lung cancer receiving myelosuppressive therapy. Although the number of studies currently published is still limited, lipegfilgrastim seems to be a promising drug in the management of chemotherapy-induced neutropenia.

Is preemptive antifungal therapy a good alternative to empirical treatment in prolonged febrile neutropenia?

2016-06-01

Full Text Available La neutropenia febril prolongada conlleva un alto riesgo de desarrollar infecciones fúngicas invasoras, por lo que habitualmente se administra terapia antifúngica empírica en estos casos. Sin embargo, esta se asocia a importantes efectos adversos, por lo que se ha propuesto como alternativa la estrategia "preemptive" o anticipada, es decir, la indicación de antifúngicos sólo ante la evidencia indirecta de infección fúngica invasora. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos tres revisiones sistemáticas que en conjunto incluyen doce estudios. Cuatro estudios aleatorizados evaluaron la pregunta abordada en este artículo. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que no está claro si la estrategia "preemptive" tiene algún efecto sobre la mortalidad porque la certeza de la evidencia es muy baja, pero podría disminuir levemente el uso de antifúngicos en pacientes con neutropenia febril prolongada.

Full Text Available TAS-102 significantly improves overall survival in patients with metastatic colorectal cancer. The most common adverse event of TAS-102 is bone marrow suppression, which leads to neutropenia. The incidence of neutropenia is high, and there is no known effective prevention method. Furthermore, the administration method of TAS-102 is complicated. We reported that neutropenia could be avoided by changing to a simple administration method of TAS-102.

Full Text Available Prompt therapy with high-dose intravenous benzylpenicillin for a prolonged period is critical for neurosyphilis patients to avoid irreversible sequelae. However, life-threatening neutropenia has been reported as a complication of prolonged therapy with high doses of benzylpenicillin when treating other diseases. This study aimed to investigate the incidence, presentation, management and prognosis of benzylpenicillin-induced neutropenia in treating neurosyphilis based on a large sample of syphilis patients in Shanghai.Between 1st January 2013 and 31st December 2015, 1367 patients with neurosyphilis were treated with benzylpenicillin, 578 of whom were eligible for recruitment to this study. Among patients without medical co-morbidities, the total incidence of benzylpenicillin-induced neutropenia and severe neutropenia was 2.42% (95% CI: 1.38-4.13% and 0.35% (95% CI: 0.06-1.39%, respectively. The treatment duration before onset of neutropenia ranged from 10 to 14 days, with a total cumulative dose of between 240 and 324 megaunits of benzylpenicillin. Neutropenia was accompanied by symptoms of chills and fever (5 patients, fatigue (2 patients, cough (1 patient, sore throat (1 patient, diarrhea (1 patient and erythematous rash (1 patient. The severity of neutropenia was not associated with age, gender or type of neurosyphilis (p>0.05. Neutropenia, even when severe, was often tolerated and normalized within one week. A more serious neutropenia did not occur when reinstituting benzylpenicillin in patients with mild or moderate neutropenia nor when ceftriaxone was used three months after patients had previously experienced severe neutropenia.Benzylpenicillin-induced neutropenia was uncommon in our cohort of patients. Continuation of therapy was possible with intensive surveillance for those with mild or moderate neutropenia. For severe neutropenia, it is not essential to aggressively use hematopoietic growth factors or broad-spectrum antibiotics for

The periodontal status and treatment of three teenagers in a Finnish family with familial neutropenia is described. The mother was also diagnosed with neutropenia. At initial examination, the 15-year-old male and the 10-year-old female had severe periodontitis, whereas the 13-year-old male had oral ulcerations but no significant periodontal disease. The two siblings with periodontitis were treated and followed approximately 5 years. It was concluded that periodontal therapy including scaling, surgery, and use of antimicrobial agents can be successful in patients with familial neutropenia, and that such patients are not necessarily candidates for full mouth extraction. The role of granulocyte colony-stimulating factor in which was used in the treatment of these patients remains to be established.

A patient with primary biliary cirrhosis and associated refractory immune thrombocytopenic purpura was treated with 4 weekly courses of rituximab, a monoclonal antibody targeting B-cell surface antigen CD20. Her thrombocyte count and even cholestatic liver function tests improved. However, 17 weeks after rituximab treatment, she developed severe neutropenia (absolute neutrophil count 0.23x10(3)/mul) and recurrent thrombocytopenia with abnormal bone marrow of all three lineages. Although delayed-onset neutropenia has been reported after rituximab, reactivated viral infections have also been encountered. Parvovirus B19 was suspected and confirmed as the cause of neutropenia in our patient. The patient was supported by GCSF treatment and recovered uneventfully after several weeks. Neutropenia after rituximab can also be the predominant manifestation of reactivated parvovirus B19 infection and have a favorable prognosis.

Indomethacin-associated neutropenia with subsequent Gram-negative sepsis in a preterm infant. Cause or coincidence?

Bengtsson, B-O S; Milstein, J M; Sherman, M P

2006-06-01

A preterm male infant with a patent ductus arteriosus developed neutropenia during treatment with indomethacin. Afterward, the mother described her own history of indomethacin-associated neutropenia. During the recovery from the neutropenia, the infant became septic with bacteremia caused by Enterobacter cloacae. Although indomethacin-related neutropenia has been described in adults, no case in a neonate has been reported. If neutropenia occurs after indomethacin therapy in a neonate, a familial history of indomethacin-associated neutropenia should be sought and the increased risk of infection should be considered.

REFRACTORY THROMBOCYTOPENIA AND NEUTROPENIA: A DIAGNOSTIC CHALLENGE

Full Text Available Background. The 2008 WHO classification identified refractory cytopenia with unilineage dysplasia (RCUD as a composite entity encompassing refractory anemia, refractory thrombocytopenia (RT, and refractory neutropenia (RN, characterized by 10% or more dysplastic cells in the bone marrow respective lineage. The diagnosis of RT and RN is complicated by several factors.  Diagnosing RT first requires exclusion of familial thrombocytopenia, chronic auto-immune thrombocytopenia, concomitant medications, viral infections, or hypersplenism. Diagnosis of RN should also be made after ruling out differential diagnoses such as ethnic or familial neutropenia, as well as acquired, drug-induced, infection-related or malignancy-related neutropenia. An accurate quantification of dysplasia should be performed in order to distinguish RT or RN from the provisional entity named idiopathic cytopenia of unknown significance (ICUS. Cytogenetic analysis, and possibly in the future somatic mutation analysis (of genes most frequently mutated in MDS, and flow cytometry analysis aberrant antigen expression on myeloid cells may help in this differential diagnosis. Importantly, we and others found that, while isolated neutropenia and thrombocytopenia are not rare in MDS, those patients can generally be classified (according to WHO 2008 classification as refractory cytopenia with multilineage dysplasia or refractory anemia with excess blasts, while RT and RN (according to WHO 2008 are quite rare.These results suggest in particular that identification of RT and RN as distinct entities could be reconsidered in future WHO classification updates.

The empirical administration of a broad-spectrum beta-lactam antibiotic, either as monotherapy or in combination with an aminoglycoside, is an essential component of the initial management of patients with fever and severe neutropenia. Multiple antibiotics have been tested for this indication. Cefepime is a fourth-generation cephalosporin with in vitro activity against most gram-negative and many gram-positive bacteria. We have studied the use of this agent as monotherapy in this indication. One hundred and twenty-six episodes of febrile neutropenia in 98 adults with hematological malignancies were treated with cefepime monotherapy. Cefepime was given at a dose of 2 g every 8 h i.v. Most episodes (49%) were fever of unexplained origin, while a microbiologically documented and clinically documented infection occurred in 25% episodes each. Seventy-six (61%) episodes occurred after conventional chemotherapy, while 51 (41%) after a hematopoietic stem cell transplantation. Twelve episodes (10%) were not evaluable for response. Among the 114 evaluable episodes, 69 (55% of the initial sample and 61% of those evaluable) responded to cefepime monotherapy, while therapy failed in 45 cases (36% of the initial sample and 39% of those evaluable), including 14 cases who developed breakthrough bacteremia during therapy. There were no deaths due to bacterial infection. At the end of all antibiotic therapy (final outcome) 69 episodes were cured only with monotherapy, 47 were cured with modification of therapy and 10 patients died from an unrelated cause. The only variable that appeared to correlate with response to therapy was the duration of neutropenia, which was longer among patients who failed or developed breakthrough bacteremia than among those who responded to monotherapy. Initial empirical antibiotic therapy with cefepime as a single agent in patients with febrile neutropenia and a hematological malignancy is effective, but patients with prolonged neutropenia appear to be

A 12-year-old daughter of consanguineous Moroccan parents was diagnosed with cyclic neutropenia, based on a combination of recurrent gingivostomatitis, a fluctuating neutrophil count, and several episodes of severe neutropenia. No ELA2 gene mutations were found. At age 19 years she presented with edema of the limbs, proteinuria and renal failure. Renal amyloidosis AA was diagnosed by biopsy. Gene mutations associated with family Mediterranean fever (FMF) were sought, and a homozygous mutation (M694V) was found in the MFEV gene. This is the novel finding of FMF that masqueraded as cyclic neutropenia. (c) 2008 Wiley-Liss, Inc.

Severe neutropenia is a common dose-limiting side effect of adjuvant breast cancer chemotherapy. We aimed to test the hypothesis that weak circadian rhythm is associated with an increased risk of neutropenia using a cohort study. We consecutively recruited 193 breast cancer patients who received adjuvant chemotherapy (5-fluorouracil, epirubicin, and cyclophosphamide followed by docetaxel; doxorubicin and cyclophosphamide; docetaxel and cyclophosphamide). Participants wore a wrist actigraph continuously for 168 h at the beginning of chemotherapy. Values of percent rhythm and double amplitude below medians represented weak circadian rhythm. Mesor measured the mean activity level and acrophase symboled the peak time of the rhythm. We used Cox proportional hazard regression model to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) of grade 4 neutropenia and febrile neutropenia in relation to actigraphy-derived parameters. Low levels of percent rhythm (HR:2.59, 95% CI 1.50-4.72), double amplitude (HR:2.70, 95% CI 1.51-4.85), and mesor (HR: 2.48, 95% CI 1.44-4.29) were positively associated with the risk of grade 4 neutropenia during chemotherapy. Low levels of percent rhythm (HR: 2.41, 95% CI 1.02-5.69) and double amplitude (HR:2.49, 95% CI 1.05-5.90) were also associated with increased risks of febrile neutropenia. The HRs for acrophase were not statistically significant. This study provides the first epidemiological evidence that increased risks of grade 4 neutropenia and febrile neutropenia are associated with weak circadian rhythm among adjuvant breast cancer patients. The results suggest that circadian rhythm might be one potential target for the prevention of chemotherapy-induced neutropenia among cancer patients.

Arboviruses are a common cause of fever in the returned traveler often associated with leucopenia, especially lymphopenia and thrombocytopenia. Transient neutropenia has been described in a few cases of arboviruses. However, prolonged and severe neutropenia (dengue fever, especially in the returned traveler in Europe. A 26-year-old healthy female without any medical past history, flying back from Thailand, presented a transient fever with severe neutropenia (dengue fever. Outcome was favorable without any antimicrobial therapy. Physicians should be wary of possible unusual presentation of dengue fever with prolonged neutropenia. Although such biological sign is more often associated with malaria or severe bacterial infection, it may be a sign of arbovirus.

We describe the management of a 4-year-old child with acute lymphoblastic leukaemia (ALL) who presented with febrile neutropenia, Cryptosporidium and subsequently developed refeeding syndrome. Febrile neutropenia is common and can be life-threatening and we highlight the identification of well low-risk neutropenic children with resolved febrile illnesses suitable for early discharge. We also discuss the potential management strategies for Cryptosporidium Refeeding syndrome is not common, but should be considered as a cause of acute inpatient deterioration and is a significant risk, with potential morbidity, in children who have undergone a period of catabolism.

2012-09-01

Full Text Available OBJECTIVE: Patients with neutropenia due to cancer chemotherapy are prone to severe infections. Cancer patients can experience >1 infectious episode during the same period of neutropenia. This study aimed to determine the etiological and clinical characteristics of secondary infectious episodes in cancer patients with febrile neutropenia and to identify the factors associated with the risk of secondary infectious episodes. METHODS: All cancer patients that received antineoplastic chemotherapy at Ankara University, School of Medicine, Department of Hematology between May 2004 and May 2005 and developed neutropenia were included in the study. Data were collected using survey forms that were completed during routine infectious diseases consultation visits. Categorical data were analyzed using the chi-square test, whereas Student’s t-test was used for continuous variables. Multivariate logistic regression analysis was performed to identify independent predictors of secondary infections (SIs. RESULTS: SIs were observed during 138 (53% of 259 febrile neutropenic episodes. Of the 138 episodes, 89 (64.5% occurred in male patients with a mean age of 40.9 years (range: 17-76 years. In total, 80% of the SIs were clinically or microbiologically documented. Factors on d 4 of the initial febrile episode were analyzed via a logistic regression model. The presence of a central intravenous catheter (OR: 3.01; P < 0.001, acute myeloid leukemia (AML as the underlying disease (OR: 2.12; P = 0.008, diarrhea (OR: 4.59; P = 0.005, and invasive aspergillosis (IA during the initial febrile episode (OR: 3.96; P = 0.009 were statistically significant risk factors for SIs. CONCLUSION: Among the cancer patients with neutropenia in the present study, AML as the underlying disease, the presence of a central venous catheter, diarrhea, and IA during the initial febrile episode were risk factors for the development of SIs.

Treatment of oncology patient using cytotoxic drugs has the neutropenia and its infectious complications as the commonest dose-limiting toxicity. Its appearance provokes dose delays and reduction during post-chemotherapy cycles, as well as the quality of life deterioration of patients. Oncology Medicine Group including the Pharmacy Service carried out a study to analyze the appearance of febrile neutropenia after cytotoxic therapy administration, and the presence of other factors that may to increase the risk to these reactions. A total of 42 patients were studied admitted with febrile neutropenia after above therapy from February to August, 2007. Biomedical variables from included patient group were achieved and the previously applied cytostatic therapy. The prevalent age-group was those patients aged over 50 and predominance of male sex and advanced stages with associated affections. The more frequent tumor locations were in breast, lung, and non-Hodgkin lymphoma. The cytostatic agent more used in cases of febrile neutropenia was Adriamycin (71.4 %) followed by Cyclophosphamide (52.4 %). The factors more associated with febrile neutropenia appearance were: Anthracycline chemotherapy, age over 50, advanced stages, and presence of associated diseases

A 4-year-old, intact male Shiba dog was referred to Yamaguchi University Animal Medical Center, Yamaguchi, Japan, for the following complaints: anorexia, lethargy, intermittent fever, gingival bleeding and abdominal purpura. The dog presented with persistent neutropenia. Histopathological examination of a bone marrow sample revealed round to oval structures that resembled Hepatozoon micromerozoites and formed a "wheel-spoke" pattern. Furthermore, mature neutrophils were observed around these structures. PCR and sequencing using bone marrow aspirate confirmed Hepatozoon canis (H. canis) infection. These findings suggest that the neutropenia observed in this case was associated with osteomyelitis due to H. canis infection. This is the first report of neutropenia associated with H. canis infection. H. canis infection can be included in the differential diagnosis in canine cases of neutropenia in areas where the disease is endemic.

Full Text Available OBJECTIVES: to identify the prevalence, and describe the management of, neutropenia throughout the chemotherapy treatment among women with breast cancer.METHODS: observational study, cycles of chemotherapy. 116 neutropenic events were recorded, and 63.3% of the patients presented neutropenia at some point of their treatment, 46.5% of these presenting grade II. The management used was temporary suspension between the cycles and the mean number of delays was 6 days. The study was prospective and longitudinal, where the evaluation of the hematological toxicities was undertaken at each cycle of chemotherapy, whether neoadjuvant or adjuvant.RESULTS: 79 women were included, who received 572 cycles. However, the reasons for the suspensions were the lack of a space in the chemotherapy center, followed by neutropenia.CONCLUSION: neutropenia is one of the most common and serious adverse events observed during the chemotherapy. Nursing must invest in research regarding this adverse event and in management strategies for organizing the public health system, so as to offer quality care.

Healthcare claims databases have been used in several studies to characterize the risk and burden of chemotherapy-induced febrile neutropenia (FN) and effectiveness of colony-stimulating factors against FN. The accuracy of methods previously used to identify FN in such databases has not been formally evaluated. Data comprised linked electronic medical records from Geisinger Health System and healthcare claims data from Geisinger Health Plan. Subjects were classified into subgroups based on whether or not they were hospitalized for FN per the presumptive "gold standard" (ANC based definition (diagnosis codes for neutropenia, fever, and/or infection). Accuracy was evaluated principally based on positive predictive value (PPV) and sensitivity. Among 357 study subjects, 82 (23%) met the gold standard for hospitalized FN. For the claims-based definition including diagnosis codes for neutropenia plus fever in any position (n=28), PPV was 100% and sensitivity was 34% (95% CI: 24-45). For the definition including neutropenia in the primary position (n=54), PPV was 87% (78-95) and sensitivity was 57% (46-68). For the definition including neutropenia in any position (n=71), PPV was 77% (68-87) and sensitivity was 67% (56-77). Patients hospitalized for chemotherapy-induced FN can be identified in healthcare claims databases--with an acceptable level of mis-classification--using diagnosis codes for neutropenia, or neutropenia plus fever.

To describe parent preference for treatment of febrile neutropenia and the key drivers of parental decision making, structured face-to-face interviews were used to elicit parent preferences for inpatient versus outpatient management of pediatric febrile neutropenia. Parents were presented with 4 different scenarios and asked to indicate which treatment option they preferred and to describe reasons for this preference during the face-to-face interview. Comments were recorded in writing by research assistants. A consensus approach to thematic analysis was used to identify themes from the written comments of the research assistants. A total of 155 parents participated in the study. Of these, 80 (51.6%) parents identified hospital-based intravenous treatment as the most preferred treatment scenario for febrile neutropenia. The major themes identified included convenience/disruptiveness, physical health, emotional well-being, and modifiers of parental decision making. Most parents preferred hospital-based treatment for febrile neutropenia. An understanding of issues that influence parental decision making may assist health care workers in planning program implementation and further support families in their decision-making process.

Full Text Available Moxifloxacin is commonly prescribed in the inpatient and outpatient management of community-acquired pneumonia and other common infections. We report a case of a 76-year-old man who developed severe neutropenia after several days of treatment for community-acquired pneumonia. The patient had a history of alcohol abuse; however, there were no other offending medications prescribed, and a thorough laboratory workup for other possible causes of neutropenia was negative. The patient’s neutrophils and white blood count responded quickly to cessation of fluoroquinolones. This case highlights the importance of identifying patients that might be at high risk for neutropenia that may need closer monitoring on this commonly prescribed medication.

Background: Radiation-induced oesophagitis is a major side effect of concurrent chemotherapy and radiotherapy. A strong association between neutropenia and oesophagitis was previously shown, but external validation and further elucidation of the possible mechanisms are lacking. Methods and patients: A total of 119 patients were included at two institutions. The concurrent group comprised 34 SCLC patients treated with concurrent carboplatin and etoposide, and concurrent chest irradiation, and 36 NSCLC patients with concurrent cisplatin and etoposide, and concurrent radiotherapy, while the sequential group comprised 49 NSCLC patients received sequential cisplatin and gemcitabine, and radiotherapy. Results: Severe neutropenia was very frequent during concurrent chemoradiation (grade: 4 41.4%) and during induction chemotherapy in sequentially treated patients (grade 4: 30.6%), but not during radiotherapy (only 4% grade 1). In the concurrent group, the odds ratios of grade 3 oesophagitis vs. neutropenia were the following: grade 2 vs. grade 0/1: 5.60 (95% CI 1.55-20.26), p = 0.009; grade 3 vs. grade 0/1: 10.40 (95% CI 3.19-33.95); p = 0.0001; grade 4 vs. grade 0/1: 12.60 (95% CI 4.36-36.43); p < 0.00001. There was no correlation between the occurrence of neutropenia during induction chemotherapy and acute oesophagitis during or after radiotherapy alone. In the univariate analysis, total radiation dose (p < 0.001), overall treatment time of radiotherapy (p < 0.001), mean oesophageal dose (p = 0.038) and neutropenia (p < 0.001) were significantly associated with the development of oesophagitis. In a multivariate analysis, only neutropenia remained significant (p = 0.023). Conclusion: We confirm that neutropenia is independently correlated with oesophagitis in concurrent chemoradiation, but that the susceptibility for chemotherapy-induced neutropenia is not associated with radiation-induced oesophagitis. Further studies focusing on the underlying mechanisms are thus

In a multivariate analysis, only neutropenia remained significant (p = 0.023). Conclusion: We confirm that neutropenia is independently correlated with oesophagitis in concurrent chemoradiation, but that the susceptibility for chemotherapy-induced neutropenia is not associated with radiation-induced oesophagitis. Further studies focusing on the underlying mechanisms are thus

Full Text Available Background: Febrile neutropenia is an important cause of mortality and morbidity in hematology-oncology patients undergoing chemotherapy. The management of febrile neutropenia is typically algorithm-driven. The aim of this study was to assess the results of a standardized protocol for the treatment of febrile neutropenia. Methods: A retrospective cohort study (2011-2012 was conducted of patients with high-risk neutropenia in a hematology-oncology service. Results: Forty-four episodes of 17 patients with a median age of 48 years (range: 18-78 years were included. The incidence of febrile neutropenia was 61.4%. The presence of febrile neutropenia was associated with both the duration and severity of neutropenia. Microbiological agents were isolated from different sources in 59.3% of the episodes with bacteremia iso- lated from blood being the most prevalent (81.3%. Multiple drug-resistant gram-negative bacilli were isolated in 62.5% of all microbiologically documented infections. Treatment of 63% of the episodes in which the initial treatment was piperacillin/tazobactam needed to be escalated to meropenem. The mortality rate due to febrile neutropenia episodes was 18.5%. Conclusion: The high rate of gram-negative bacilli resistant to piperacillin/tazobactam (frontline antibiotics in our protocol and the early need to escalate to carbapenems raises the question as to whether it is necessary to change the current protocol.

Full Text Available A doença infecciosa contribui para uma elevada morbilidade e mortalidade no doente oncológico, representando a pneumonia adquirida na comunidade a mais frequente. O desenvolvimento de PAC no doente neoplásico parece advir da modificação de mecanismos de defesa imunitária resultante, quer da patologia maligna, quer do tratamento oncológico. O risco de infecção relacionada com o tipo de neoplasia pode associar-se ao défice de imunidade humoral, celular ou do número de neutrófilos. As doenças hematológicas malignas podem predispor o doente às infecções devido à substituição da medula por células neoplásicas. Consequentemente, estes doentes têm neutropenia funcional, apesar de apresentarem, muitas vezes, um número normal ou aumentado de neutrófilos. Por outro lado, estes doentes podem ter neutropenia como efeito secundário da quimioterapia e/ou radioterapia (neutropenia absoluta. A gravidade da neutropenia foi considerada como principal factor de risco isolado no doente neoplásico, com particular relevância se o número de neutrófilos ≤500cel/mm³. A mortalidade global atribuída à neutropenia febril no doente neoplásico é de 30-50%. Nas últimas décadas, o tratamento das infecções na população oncológica foi direccionado, primariamente, para o manuseamento da neutropenia febril, devido ao facto de o local da infecção não ser determinado em 50-80% dos casos. As guidelines da American Thoracic Society de 2001 utilizavam a neutropenia para identificar os quadros mais graves de PAC nos doentes oncológicos. Os doen tes com patologia hematológica e neutropenia funcional ou indivíduos com qualquer tipo de neoplasia e neutropenia absoluta foram excluídos das referidas guidelines. A decisão de incluir doentes com tumores sólidos não neutropénicos foi baseada, apenas, na opinião de especialistas. Assim, os clínicos podiam sentir-se confiantes e tratar a PAC no doente oncológico não neutropénico como na

Full Text Available Abstract Background Healthcare claims databases have been used in several studies to characterize the risk and burden of chemotherapy-induced febrile neutropenia (FN and effectiveness of colony-stimulating factors against FN. The accuracy of methods previously used to identify FN in such databases has not been formally evaluated. Methods Data comprised linked electronic medical records from Geisinger Health System and healthcare claims data from Geisinger Health Plan. Subjects were classified into subgroups based on whether or not they were hospitalized for FN per the presumptive “gold standard” (ANC 9/L, and body temperature ≥38.3°C or receipt of antibiotics and claims-based definition (diagnosis codes for neutropenia, fever, and/or infection. Accuracy was evaluated principally based on positive predictive value (PPV and sensitivity. Results Among 357 study subjects, 82 (23% met the gold standard for hospitalized FN. For the claims-based definition including diagnosis codes for neutropenia plus fever in any position (n=28, PPV was 100% and sensitivity was 34% (95% CI: 24–45. For the definition including neutropenia in the primary position (n=54, PPV was 87% (78–95 and sensitivity was 57% (46–68. For the definition including neutropenia in any position (n=71, PPV was 77% (68–87 and sensitivity was 67% (56–77. Conclusions Patients hospitalized for chemotherapy-induced FN can be identified in healthcare claims databases--with an acceptable level of mis-classification--using diagnosis codes for neutropenia, or neutropenia plus fever.

Full Text Available Brucellosis is a systemic disease in which all kind of tissues and organs can be affected. Brucellosis may present with different symptoms and symptoms are non-specific. A broad spectrum of clinical manifestations can be seen, therefore diagnosis can be difficult. Cutaneous complications and febrile neutropenia have been rarely reported. Here, a rare brucellosis case was reported that he applied with fever, skin eruption and neutropenia. We emphasized that especially in endemic areas brucellosis should always be kept on mind in the differential diagnosis of patient with skin eruption and febril neutropenia.J Microbiol Infect Dis 2014;4(1: 39-41

Full Text Available Se estudiaron en forma retrospectiva 441 historias clínicas en el período comprendido entre enero de 2003 y diciembre de 2005. De éstas, se identificaron las características de 117 episodios de neutropenia febril en 96 pacientes. La mediana de edad fue 34 años y el 56,4% de los episodios ocurrieron en hombres. Las más frecuentes neoplasias hematológicas relacionadas con neutropenia febril fueron leucemia linfoide aguda (LLA y leucemia mieloide aguda (LMA con 45 episodios de cada una, que corresponden al 76,9%. La mediana de duración de la neutropenia fue 8 días y el 60,7% de los casos entraron en la categoría de neutropenia grave. La mortalidad global fue del 32% y el 81,5% de estas muertes estuvieron asociadas directamente con la infección. Se obtuvo aislamiento microbiológico en el 51% de los eventos. Los bacilos gram negativos (BGN constituyeron el 59% de los aislamientos microbiológicos y los cocos gram positivos el 32%. El 14,3% de los BGN aislados fueron positivos para beta lactamasas de espectro extendido (BLEE y la resistencia global a ciprofloxacina alcanzó el 31,4%. El esquema antimicrobiano empírico más frecuentemente utilizado fue ciprofloxacina más ceftriaxona; la respuesta terapéutica fue desfavorable en 65% de los casos. En el Hospital San Vicente de Paúl de Medellín siguen primando los gérmenes gram negativos y son altas las tasas de resistencia a los antibióticos utilizados tradicionalmente como de primera línea, lo que sugiere la necesidad de reevaluar la pertinencia de estos esquemas.

Full Text Available Las intoxicaciones alimentarias son ocasionadas por consumo de alimentos en malas condiciones de preparación o de conservación o que han sufrido contaminación con agentes quimicos, fisicos o biológicos. La reciente incorporación de la vigilancia de este evento en el sistema de vigilancia intensificado de la Secretaria de Salud del Amazonas, ha permitido identificar la presencia de brotes de intoxicación alimentaria en el departamento. En abril de 1997, se informó a la Oficina de Epidemiologia de la Secretaria de Salud del Amazonas, la llegada de 30 pacientes al Hospital Empresa Social del Estado San Rafael de Leticia, con un cuadro clinico de dolor abdominal, vómito y cefalea. Las pacientes eran estudiantes adolescentes del internado indígena femenino de Nazareth, que presentaban como antecedente común la ingestión de pescado recalentado el día anterior a su consulta. En la investigación del presente brote de intoxicación alimentaria se comprobó por laboratorio que el alimento implicado era la carne de caimán negro, Melanosuchusniger, contaminada con Bacillus cereus. Esta carne iba a ser vendida como 'pescado seco' en Bogotá, por la gran demanda que tiene este alimento en la época de Semana Santa.

Common variable immunodeficiency (CVID) is characterized by infections and hypogammaglobulinemia. Neutropenia is rare during CVID. The French DEFI study enrolled patients with primary hypogammaglobulinemia. Patients with CVID and neutropenia were retrospectively analyzed. Among 473 patients with CVID, 16 patients displayed neutropenia (lowest count [0-1400]*10 6 /L). Sex ratio (M/F) was 10/6. Five patients died during the follow-up (11 years) with an increased percentage of deaths compared to the whole DEFI group (31.3 vs 3.4%, P < 0.05). Neutropenia was diagnosed for 10 patients before 22 years old. The most frequent symptoms, except infections, were autoimmune cytopenia, i.e., thrombopenia or anemia (11/16). Ten patients were affected with lymphoproliferative diseases. Two patients were in the infection only group and the others belonged to one or several other CVID groups. The median level of IgG was 2.6 g/L [0.35-4.4]. Most patients presented increased numbers of CD21 low CD38 low B cell, as already described in CVID autoimmune cytopenia group. Neutropenia was considered autoimmune in 11 cases. NGS for 52 genes of interest was performed on 8 patients. No deleterious mutations were found in LRBA, CTLA4, and PIK3. More than one potentially damaging variant in other genes associated with CVID were present in most patients arguing for a multigene process. Neutropenia is generally associated with another cytopenia and presumably of autoimmune origin during CVID. In the DEFI study, neutropenia is coupled with more severe clinical outcomes. It appears as an "alarm bell" considering patients' presentation and the high rate of deaths. Whole exome sequencing diagnosis should improve management.

Current guidelines do not recommend G-CSF for patients with risk factors for neutropenia. One-hundred patients undergoing chemotherapy were randomized to treatment with G-CSF at 5 Kg/kg for established febrile neutropenia (ANC <1000/microl) (Group A) or G-CSF at 263 Kg/day if ANC was 1500/microl or less on the day of the expected nadir, with the duration of treatment determined by the severity of neutropenia (Group B). The number of doses of G-CSF was similar in the two groups. There were 34 cases of febrile neutropenia in Group A, but none in Group B (p=0.0001). Hospital admission for febrile neutropenia, antibiotic use and delays in chemotherapy were all significantly more common in Group A. Total direct costs were estimated to be 66, 646 for Group A and 47, 119 for Group B. Tailoring treatment does not increase G-CSF use, but significantly reduces febrile neutropenia and treatment delays and lowers direct costs.

Infusional β-lactam antibiotics in febrile neutropenia: has the time come?

Abbott, Iain J; Roberts, Jason A

2012-12-01

Febrile neutropenia presents a clinical challenge in which timely and appropriate antibiotic exposure is crucial. In the context of altered pharmacokinetics and rising bacterial resistance, standard antibiotic doses are unlikely to be sufficient. This review explores the potential utility of altered dosing approaches of β-lactam antibiotics to optimize treatment in febrile neutropenia. There is a dynamic relationship between the antibiotic, the infecting pathogen, and the host. Great advancements have been made in the understanding of the pharmacokinetic changes in critical illness and the pharmacodynamic relationships of antibiotics in these settings. Antibiotic treatment in febrile neutropenia is becoming increasingly difficult. Patients are of higher acuity, receive more intensive chemotherapy regimens leading to prolonged neutropenia, and are often exposed to multiple antibiotic courses. These patients display significant variability in antibiotic clearances and increases in volume of distribution compared with standard ward-based patients. Rising antibiotic resistance and a lack of new antibiotics in production have prompted alternative dosing strategies based on pharmacokinetic/pharmacodynamic data, such as extended or continuous infusions of β-lactam antibiotics, to maximize the likelihood of treatment success. A definitive study that describes a mortality benefit of such dosing regimens remains elusive and the theoretical advantages require testing in well designed clinical trials.

Febrile neutropenia is a frequent adverse event experienced by people with cancer who are undergoing chemotherapy, and is a potentially life-threatening situation. The current treatment is supportive care plus antibiotics. Colony-stimulating factors (CSFs), such as granulocyte-CSF (G-CSF) and granulocyte-macrophage CSF (GM-CSF), are cytokines that stimulate and accelerate the production of one or more cell lines in the bone marrow. Clinical trials have addressed the question of whether the addition of a CSF to antibiotics could improve outcomes in individuals diagnosed with febrile neutropenia. However, the results of these trials are conflicting. To evaluate the safety and efficacy of adding G-CSF or GM-CSF to standard treatment (antibiotics) when treating chemotherapy-induced febrile neutropenia in individuals diagnosed with cancer. We conducted the search in March 2014 and covered the major electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS, and SCI. We contacted experts in hematology and oncology and also scanned the citations from the relevant articles. We searched for randomized controlled trials (RCTs) that compared CSF plus antibiotics versus antibiotics alone for the treatment of chemotherapy-induced febrile neutropenia in adults and children. We used the standard methodological procedures expected by The Cochrane Collaboration. We performed meta-analysis of the selected studies using Review Manager 5 software. Fourteen RCTs (15 comparisons) including a total of 1553 participants addressing the role of CSF plus antibiotics in febrile neutropenia were included. Overall mortality was not improved by the use of CSF plus antibiotics versus antibiotics alone (hazard ratio (HR) 0.74 (95% confidence interval (CI) 0.47 to 1.16) P = 0.19; 13 RCTs; 1335 participants; low quality evidence). A similar finding was seen for infection-related mortality (HR 0.75 (95% CI 0.47 to 1.20) P = 0.23; 10 RCTs; 897

Severe congenital neutropenia (SCN) is a heterogeneous group of disorders with a defect in granulopoiesis causing marked neutropenia and severe bacterial infections. A 17-month-old girl (patient 1) was admitted due to cervical lymphadenitis caused by methicillin-resistant Staphylococcus aureus, with neutropenia. She had Pseudomonas aeruginosa sepsis and peritonitis with perforated appendicitis at 8-month of age. Her sister, a 37-month-old girl (patient 2), had recurrent stomatitis with profound neutropenia, and her mother, a 32-yr-old woman (patient 3), had had recurrent stomatitis until her early 20s with neutropenia. We found an ELANE gene mutation (c.597+1G > A) from them in direct DNA sequencing analysis. Patients 1 and 2 did not respond to granulocyte colony stimulating factor and patient 1 was treated with prolonged antibiotics and excision. We demonstrated inherited SCN cases showing different severity even with the same mutation of the ELANE gene in a family.

Full Text Available Use of antibiotics is required in febrile neutropenia therapy. The variety choice on the use of antibiotics has increased the role of pharmacoeconomics study to determine the most effective and efficient antibiotic in a specific area. The purpose of this study was to investigate the lowest cost antibiotic between meropenem and ceftazidime that were used as one of febrile neutropenia treatments at one of referral hospitals in West Java province during 2011–2013. This study was a retrospective, observational and analytical study that was performed on February 2014 by collecting medical record data related to febrile neutropenia inpatient who received meropenem or ceftazidime therapy. The result showed that although it was not statistically significant, the total cost for ceftazidime therapy was IDR7,082,523, which was lower than meropenem therapy (IDR11,094,147. Hopefully, this result can assist the health professionals in the management of febrile neutropenia therapy.

Poikiloderma with Neutropenia (PN) is inherited genodermatosis which results from a biallelic mutation in the USB1 gene (U Six Biogenesis 1). PN, first described in Navajo Native Americans, is characterized by early onset poikiloderma, pachyonychia, palmo-plantar hyperkeratosis, and permanent neutropenia. This condition results in frequent respiratory tract infections during infancy and childhood. From 2011 to 2013, four cases of PN were diagnosed in Morocco. In this paper, we report the first four cases of PN diagnosed in Morocco, out of three unrelated consanguinous families. We investigated the genetic, immunological, and clinical features of four Moroccan patients with PN from three unrelated consanguinous families. Mean age at onset was 3 months and mean age at diagnosis was 7.5 years. The diagnosis of these PN patients was made based on clinical features and confirmed by molecular analysis for three cases. We identified two undescribed homozygous mutations in the USB1 gene: c.609 + 1G>A in two siblings and c.518 T>G(p.(Leu173Arg)) in the other case. This report confirms the clinical and genetic identity of Poikiloderma with Neutropenia syndrome.

Full Text Available Background Infection in the immunocompromised host has been a reason of concern in the clinical setting and a topic of debate for decades. In this study, the aim was to analyse the clinical profile of high-risk febrile neutropenic patients. Aims To study the clinical profile of high risk febrile neutropenia patients with the objective of identifying the most common associated malignancy, most common associated pathogen, the source of infection, to correlate the treatment and management with that of the Infectious Diseases Society of America (IDSA 2010 guidelines and to assess the clinical outcome. Methods A cross-sectional time bound study was carried out and a total of 80 episodes of high-risk febrile neutropenia were recorded among patients with malignancies from September 2011 to July 2013 with each episode being taken as a new case. Results Non-Hodgkin’s lymphoma (30 per cent was the most common malignancy associated, commonest source of infection was due to central venous catheters, the commonest pathogens were gram negative (52 per cent the treatment and management of each episode of high risk febrile neutropenia correlated with that of IDSA 2010 guidelines and the mortality rate was 13.75 per cent. Conclusion Febrile neutropenia is one of the major complications and cause of mortality in patients with malignancy and hence understanding its entire spectrum can help us reduce morbidity and mortality.

Yet, the price may be a proportion of patients dying of complications due to treatment-induced infectious complications, such as neutropenia. With the aim of decreasing morbidity and mortality related to infectious complications, recombinant human granulocyte colony-stimulating factor (G-CSF, filgrastim, and pegylated filgrastim have been used to reduce time and degree of neutropenia. A biosimilar is a copy of an approved original biologic medicine whose data protection has expired. The patent for filgrastim expired in Europe in 2006 and in the US in 2013. This review analyses the available evidence to be considered in order to design a strategy of use of G-CSF and its biosimilars. The clinical and safety outcomes of biosimilars are well within the range of historically reported data for originator filgrastim. This underscores the clinical effectiveness and safety of biosimilar filgrastim in daily clinical practice. Biosimilars can play an important role by offering the opportunity to reduce costs, thus contributing to the financial sustainability of treatment programs.

The underlying cause of neutropenia may be difficult to determine due to similar clinical presentation in many neutropenic conditions. The neutrophil protein hCAP-18 (pro-LL-37) is a major component of neutrophil secondary granules and in this prospective study we assessed the use of hCAP-18 levels...... in blood plasma for differential diagnosis of neutropenic patients (n = 133) of various aetiologies. Plasma levels of hCAP-18 were determined using immunoblot and ELISA. Patients with severe congenital neutropenia (n = 23) presented with the lowest levels of plasma hCAP-18 and differential diagnostic...... diagnostic value in differential diagnosis of chronic neutropenia. Neutropenic patients with Shwachman-Diamond syndrome, Barth syndrome, Cohen syndrome, acute myeloid leukaemia and specific granule deficiency presented with reduced plasma hCAP-18 levels as well. The blood plasma level of hCAP-18 was thus low...

Full Text Available Title. Chemotherapy-induced myelosuppression lowers the quality of life in breast cancer patients and causes many complications. Traditional Chinese Medicine (TCM is a widely used complementary and alternative medicine therapies. Objective. To study whether TCM can reduce the incidence of chemotherapy-induced leukopenia, neutropenia, and febrile neutropenia (FN in breast cancer patients. Methods. The data were analyzed retrospectively between patients who received TCM treatment (group 1, n=453 and patients who did not receive TCM treatment (group 2, n=359. Significant risk factors associated with the occurrence of chemotherapy-induced leukopenia, neutropenia, and FN were identified using multivariate analysis. Propensity score-matched patients were analyzed to adjust for any baseline differences. Results. Group 1 patients had a significantly lower rate of chemotherapy-induced severe leukopenia, neutropenia, and FN, compared with group 2 (43% versus 71%, P<0.0001, 72% versus 78%, P=0.005, 6% versus 24%, P<0.0001, resp.. Multivariate analysis revealed that chemotherapy regimens containing anthracyclines combined with paclitaxel or docetaxel were the most significant predictor. Subgroup analysis indicated that TCM treatment showed benefit in relieving chemotherapy-induced leukopenia and FN in most chemotherapy regimens. Conclusions. TCM treatment could lower the risk of severe chemotherapy-induced leukopenia, neutropenia, and FN in breast cancer patients.

Full Text Available BACKGROUND: Until recently, viral infections in patients with hematological malignancies were concerns primarily in allogeneic hematopoietic stem cell transplant (HSCT recipients. During the last years, changed treatment regimens for non-transplanted patients with hematological malignancies have had potential to increase the incidence of viral infections in this group. In this study, we have prospectively investigated the prevalence of a broad range of respiratory viruses in nasopharyngeal aspirate (NPA as well as viruses that commonly reactivate after allogeneic HSCT. METHODOLOGY/PRINCIPAL FINDINGS: Patients with hematological malignancies and therapy induced neutropenia (n = 159 were screened regarding a broad range of common respiratory viruses in the nasopharynx and for viruses commonly detected in severely immunosuppressed patients in peripheral blood. Quantitative PCR was used for detection of viruses. A viral pathogen was detected in 35% of the patients. The detection rate was rather similar in blood (22% and NPA (18% with polyoma BK virus and rhinovirus as dominating pathogens in blood and NPA, respectively. Patients with chronic lymphocytic leukemia (CLL (p<0.01 and patients with fever (p<0.001 were overrepresented in the virus-positive group. Furthermore, viral findings in NPA were associated with upper respiratory symptoms (URTS (p<0.0001. CONCLUSIONS/SIGNIFICANCE: Both respiratory viral infections and low titers of viruses in blood from patients with neutropenia were common. Patients with CLL and patients with fever were independently associated to these infections, and viral findings in NPA were associated to URTS indicating active infection. These findings motivate further studies on viruses' impact on this patient category and their potential role as causative agents of fever during neutropenia.

Due to trends of population movements, Israeli family physicians are treating increasing numbers of African immigrants from Ethiopia. These immigrants were found to have complete blood counts (CBC) that are different from other ethnic groups, with a higher prevalence of eosinophilia and neutropenia. To evaluate haematological findings in an attempt to define whether they behave as familial (genetic) or environmental. Retrospective chart review of 300 patients from a primary care clinic: 100 individuals of Ethiopian heritage born in Ethiopia (EE); 100 individuals of Ethiopian heritage born in Israel, whose parents were born in Ethiopia (EI), and a control group of 100 patients who were not of Ethiopian heritage (C). Absolute eosinophilia (greater than 500/dl) was found in 13% of the EE study group significantly higher than the two other groups (P neutropenia (defined as less than 1500/dl) was found in 32% of EE group, 20% of EI, and 1% of C (P familial-genetic nature is probably the reason for the higher prevalence of neutropenia in this population, although some environmental influence may play a role. The knowledge of these findings may be useful for physicians treating people migrating from Africa.

Dose reductions, delays in treatment administration, and the use of granulocyte colony-stimulating factors are equally recommended options to preserve absolute neutrophil count in case of chemotherapy regimens bringing a risk of febrile neutropenia of 20% or higher. Recombinant granulocyte colony-stimulating factors, such as filgrastim and lenograstim, have a short elimination half-life (t1/2 and need to be used daily, while others, like pegfilgrastim and lipegfilgrastim, are characterized by a long t1/2 requiring only a single administration per cycle. Balugrastim is a novel long-acting recombinant granulocyte colony-stimulating factor obtained by means of a genetic fusion between recombinant human serum albumin and granulocyte colony-stimulating factor. Albumin binding increases the molecular weight and determines a high plasmatic stability leading to a t1/2 of ~19 days. Balugrastim’s efficacy, safety, and tolerability have been assessed in four different clinical trials involving breast cancer patients treated with doxorubicin and docetaxel. Pegfilgrastim was chosen as a comparator. Balugrastim was noninferior to pegfilgrastim with regard to the reduction of mean duration of severe neutropenia during cycle 1. Moreover, both treatments were comparable in terms of efficacy and safety profile. Balugrastim was well tolerated, with the only related adverse event being mild to moderate bone pain. The aim of this review is to summarize the

Two antibiotics recommended by the guideline of Infectious Diseases Society of America (IDSA) were selected for treatment of febrile neutropenia, and these paired antibiotics were changed periodically three times. The clinical efficacy of each antibiotic was retrospectively evaluated at the end of the final period. There was no significant difference about efficacy rate between two kinds of antibiotics in the same sequential period. However, the efficacy rate has been rising and febrile duration has been shortening by degrees. Only a few drug resistant bacteria were recognized by the surveillance culture during antibiotic cycling. Recently, antibiotic cycling therapy has attracted attention especially in the ICU. However, a clinical study of treatment for febrile neutropenia has not been reported. Our trial suggests that cycling therapy may be useful for febrile neutropenia. However, Some deviation in the patients characteristics of each period may affect the result. It seems that further examination is necessary about usefullness of the cycling therapy for febrile neutropenia.

Neutropenia can be qualified as congenital when of neonatal onset or when associated with extra-hematopoietic manifestations. Overall, 30% of patients with congenital neutropenia (CN) remain without a molecular diagnosis after a multidisciplinary consultation and tedious diagnostic strategy. In the rare situations when neutropenia is identified and associated with intellectual disability (ID), there are few diagnostic hypotheses to test. This retrospective multicenter study reports on a clinically heterogeneous cohort of 10 unrelated patients with CN associated with ID and no molecular diagnosis prior to whole-exome sequencing (WES). WES provided a diagnostic yield of 40% (4/10). The results suggested that in many cases neutropenia and syndromic manifestations could not be assigned to the same molecular alteration. Three sub-groups of patients were highlighted: (i) severe, symptomatic chronic neutropenia, detected early in life, and related to a known mutation in the CN spectrum (ELANE); (ii) mild to moderate benign intermittent neutropenia, detected later, and associated with mutations in genes implicated in neurodevelopmental disorders (CHD2, HUWE1); and (iii) moderate to severe intermittent neutropenia as a probably undiagnosed feature of a newly reported syndrome (KAT6A). Unlike KAT6A, which seems to be associated with a syndromic form of CN, the other reported mutations may not explain the entire clinical picture. Although targeted gene sequencing can be discussed for the primary diagnosis of severe CN, we suggest that performing WES for the diagnosis of disorders associating CN with ID will not only provide the etiological diagnosis but will also pave the way towards personalized care and follow-up. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Full Text Available Abstract Background Patients with cancer must make frequent visits to the clinic not only for chemotherapy but also for the management of treatment-related adverse effects. Neutropenia, the most common dose-limiting toxicity of myelosuppressive chemotherapy, has substantial clinical and economic consequences. Colony-stimulating factors such as filgrastim and pegfilgrastim can reduce the incidence of neutropenia, but the clinic visits for these treatments can disrupt patients' routines and activities. Methods We surveyed patients to assess how clinic visits for treatment with chemotherapy and the management of neutropenia affect their time and activities. Results The mean amounts of time affected by these visits ranged from approximately 109 hours (hospitalization for neutropenia and 8 hours (physician and chemotherapy to less than 3 hours (laboratory and treatment with filgrastim or pegfilgrastim. The visits for filgrastim or pegfilgrastim were comparable in length, but treatment with filgrastim requires several visits per chemotherapy cycle and treatment with pegfilgrastim requires only 1 visit. Conclusions This study provides useful information for future modelling of additional factors such as disease status and chemotherapy schedule and provides information that should be considered in managing chemotherapy-induced neutropenia.

Immune-Mediated Neutropenia and Thrombocytopenia in a Patient with Ulcerative Colitis: An Unusual Hematological Association with IBD

1995-01-01

Full Text Available Hematological manifestations of inflammatory bowel disease (IBD are well described in the literature. However, the combination of immune-mediated neutropenia and thrombocytopenia has only been reported once in association with IBD. A case is reported of immune-mediated neutropenia and thrombocytopenia in a patient with ulcerative colitis during a relapse. No obvious causes of these hematological abnormalities were found in the patient despite an exhaustive search. An immune-mediated process was confirmed by positive antineutrophil antibody and platelet-associated antibody in the patient’s serum, and the demonstration of binding of the patient’s immunoglobulin G to autologous neutrophils. The patient was treated with high-dose steroid, intravenous gamma-globulin and eventually splenectomy. The platelet count subsequently normalized; although the severe neutropenia recurred, it has subsequently improved without further treatment. Although a definitive cause-effect relationship cannot be established, the immune-mediated neutropenia and thrombocytopenia may be an unusual hematological manifestation associated with ulcerative colitis.

Full Text Available Crizotinib, the first clinically available inhibitor of anaplastic lymphoma kinase (ALK gene rearrangement, is generally well tolerated. In contrast, neutropenia induced by crizotinib is a commonly reported grade 3 or 4 adverse event. In such cases, interruption and dose reduction of crizotinib might be necessary for some patients with severe neutropenia. However, information concerning clinical experience and management of severe neutropenia is currently limited. In this report, the successful management of crizotinib-induced neutropenia by dose reduction of crizotinib in a patient with ALK-positive non-small cell lung cancer is described.

The aim of this study was to estimate the incidence of the disease and to analyze laboratory data of 23 newborns undergoing serologic testing for alloimmune neonatal neutropenia (ANN) during the 1998-2008 period in Croatia. Laboratory data on 23 newborns undergoing serologic testing for ANN during the 1998-2008 period and epidemiologic data on the number of live births in Croatia were analyzed. Laboratory testing for ANN included serologic screening of maternal and neonatal sera and granulocytes (neutrophils) by immunofluorescence (IF) method. The monoclonal antibody immobilization of neutrophil antigens (MAINA) was employed to determine anti-HNA antibody specificity. Anti-HNA antibodies were detected in seven (54%) of 13 cases of serologically positive ANN. Only anti-HLA class I antibodies were demonstrated in four (31%) of 13 cases In the 2007-2008 period of prospective data collection, the number of serologically verified ANN cases was one case per 17,323 live births. Results of the prospective study conducted at Maternity Ward, Department of Gynecology and Obstetrics, Sestre milosrdnice University Hospital Center yielded the ANN incidence of one case per 2843 live births. Monitoring of neutrophil count in neonatal blood and serologic testing for ANN in case of isolated neutropenia in the newborn contributed considerably to timely detection of ANN.

This review focuses on the classification, diagnosis and natural history of congenital neutropenia (CN). CN encompasses a number of genetic disorders with chronic neutropenia and, for some, affecting other organ systems, such as the pancreas, central nervous system, heart, bone and skin. To date, 24 distinct genes have been associated with CN. The number of genes involved makes gene screening difficult. This can be solved by next-generation sequencing (NGS) of targeted gene panels. One of the major complications of CN is spontaneous leukaemia, which is preceded by clonal somatic evolution, and can be screened by a targeted NGS panel focused on somatic events. © 2017 John Wiley & Sons Ltd.

Neutropenia, agranulocytosis and dipyrone

Directory of Open Access Journals (Sweden)

Nelson Hamerschlak

Full Text Available CONTEXT: Neutropenia and agranulocytosis may be defined as granulocyte counts of less than 1,500/mm³ and 500/mm³, respectively. Agranulocytosis is a rare and serious disease often caused by drugs. Its mortality rate is around 10%. The most common manifestations are infections such as tonsillitis, pharyngitis, stomatitis or pneumonia. Although dipyrone is one of the drugs known to be associated with agranulocytosis, the strength of the association has been a matter of much debate. Moreover, alternative analgesic and antipyretic agents are not devoid of serious side effects. CONCLUSIONS: It is therefore necessary to establish the incidence of agranulocytosis in Latin America and the role of dipyrone. The ongoing LATIN Study is a multicenter international case-control study that will provide answers for these questions.

Full Text Available OBJETIVOS: Identificar as características das pacientes com câncer de mama que desenvolveram neutropenia febril, estabelecer fatores de risco para a sua ocorrência e indicadores de evolução desfavorável. MÉTODOS: Realizamos um estudo caso-controle com 65 pacientes. Foram incluídas 13 pacientes que desenvolveram neutropenia febril e quatro controles por caso pareados por data e número de ciclos de quimioterapia prévios, drogas e doses empregadas. Os dados clínicos e laboratoriais foram obtidos dos prontuários médicos. Utilizamos odds ratio (OR e intervalo de confiança (IC de 95% para estimar a significância dos fatores de risco. RESULTADOS: Identificamos dois fatores de risco associados à ocorrência de neutropenia febril: a realização de quimioterapia nas primeiras 24 horas após a cirurgia (OR: 159,9 IC 95%: 9,5 a 2699 e a realização concomitante de quimioterapia e radioterapia da mama (OR: 108,3 IC 95%: 4,9 a 2391. Não observamos diferenças significativas entre casos e controles quanto à idade, índice de massa corporal e contagem de neutrófilos e monócitos antes da quimioterapia. Três pacientes foram a óbito (23,1%. Duas delas tinham idade superior a 60 anos, não apresentavam comorbidades, tinham recebido o primeiro ciclo de CMF nas primeiras 24 horas após a cirurgia e tiveram infecção de sítio cirúrgico. CONCLUSÕES: Os principais fatores de risco associados a neutropenia febril em pacientes com câncer de mama foram quimioterapia nas primeiras 24 horas após a cirurgia, e uso concomitante de quimioterapia e radioterapia da mama. Nosso estudo mostra, portanto, que estas situações devem ser evitadas.PURPOSE: To identify the characteristis of patients with breast cancer who developed febrile neutropenia and to establish risk factors for its incidence and parameters for an unfavorable evolution.

Full Text Available Maternal Graves’ disease is relatively uncommon with an estimated incidence of 0.4%–1% of all pregnancies, but only 1–5% of newborns delivered to mothers with Graves’ disease develop overt clinical signs and symptoms of hyperthyroidism. Here, we describe a case of a 1380-gram female neonate who was born at 30-week gestation to a mother with Graves’ disease. Our patient presented with hyperthyroidism followed by transient hypothyroidism requiring treatment with levothyroxine. While hyperthyroid, she was treated with methimazole, iodine, and a beta-blocker. 20 days after the initiation of methimazole, she developed neutropenia. The neutrophil counts started to improve immediately after the initiation of the weaning of methimazole. To the best of our knowledge, this is the first case reported in the literature of methimazole induced neutropenia in a preterm infant being treated for neonatal Graves’ disease.

Congenital neutropenia is characterized by a severe reduction in absolute neutrophil counts, resulting in an almost total absence of neutrophils. It is well known that severe neutropenia affects periodontal status. Oral manifestations include ulcerations, gingival desquamation, gingival inflammation, attachment loss, and alveolar bone loss which may result in tooth loss. Treatment with granulocyte-colony stimulating factor (G-CSF) may improve this periodontal condition. This article reports the relationship between periodontal disease status and peripheral neutrophil levels in two consanguineous siblings with severe congenital neutropenia who did not receive routine G-CSF for 2 years prior to examination. Both siblings were given scaling, root planing, and periodontal prophylaxis in regular follow-up visits. This report demonstrates that periodontal therapy supported by adequate oral hygiene may result in restoration of neutrophil counts in siblings with congenital neutropenia.

In this exploratory, prospective study evaluated quality of life (QoL) changes in patients with diverse cancers during the first cycle of myelosuppressive chemotherapy. Of 80 patients enrolled, 71 were observed during one of five chemotherapy regimens: docetaxel; CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone); carboplatin-paclitaxel; carboplatin-docetaxel; and carboplatin-gemcitabine. Complete blood counts were taken weekly. QoL and symptom burden measures were administered at baseline and throughout the cycle, and included SF-36, Cancer Care Monitor (CCM), Hospital Anxiety and Depression Scale (HADS), and Psychosocial Adjustment to Illness Scale (PAIS). Using generalized estimating equations, we modeled the change in each measure from baseline to the end of each week using the following covariates: baseline QoL measure, baseline SF-36 Physical and Mental Health Summary scores, sex, age, cycle week, grade 4 neutropenia any time in the past 7 days (yes/no), and the interaction of the latter two covariates. Of the 71 patients observed, 33 developed grade 4 neutropenia during the first 2 weeks. Changes from baseline in SF-36 Bodily Pain, HADS Anxiety, and PAIS Social Environment scores were significantly less favorable (P<0.05) when patients experienced grade 4 neutropenia any time in the past 7 days compared to when they did not (grade 0-3). A similar, but non-significant, trend was also observed for 12 other QoL measures. QoL may be adversely affected up to 7 days after patients experience grade 4 (versus grade 0-3) neutropenia. Such findings need to be examined further in studies with adequate statistical power to test a priori hypotheses regarding specific QoL measures.

Autoimmune neutropenia of infancy is caused by neutrophil-specific autoantibodies. Primary AIN is characterized by neutrophil count familial or congenital neutropenias. To further assure the quality of the new test, we retested six samples previously tested by the gold standard method. All medical files were screened and clinical outcomes were recorded. Our method showed specificity of 85%, sensitivity of 62.5%, and a positive predictive value of 91.8%, values quite similar to those obtained by more traditional methods. The new method showed high specificity for detection of anti-neutrophil antibodies in the appropriate clinical setting and could be an effective tool for clinical decision making.

Antipsychotic drug treatment can potentially lead to adverse events such as leukopenia and neutropenia. Although these events are rare, they represent serious and life-threatening hematological side effects. We present a case study of a patient with schizoaffective disorder in a 50-year-old woman. We report a case of paliperidone extended-release (ER)-induced leukopenia and neutropenia in a female patient with schizoaffective disorder. Initiating lithium carbonate treatment and decreasing the dose of valproic acid improved the observed leukopenia and neutropenia. This treatment did not influence psychotic symptoms. The combination of paliperidone ER and valproic acid induces increased paliperidone ER plasma levels. Lithium carbonate was successfully used to treat paliperidone ER-induced leukopenia and neutropenia.

Congenital neutropenia is a group of genetic disorders that involve chronic neutropenia and susceptibility to infections. These neutropenias may be isolated or associated with immunologic defects or extra-hematopoietic manifestations. Complications may occur as infectious diseases, but also less frequently as myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). Recently, the transcription factor GATA2 has been identified as a new predisposing gene for familial AML/MDS. In the present study, we describe the initial identification by exome sequencing of a GATA2 R396Q mutation in a family with a history of chronic mild neutropenia evolving to AML and/or MDS. The subsequent analysis of the French Severe Chronic Neutropenia Registry allowed the identification of 6 additional pedigrees and 10 patients with 6 different and not previously reportedGATA2 mutations (R204X, E224X, R330X, A372T, M388V, and a complete deletion of the GATA2 locus). The frequent evolution to MDS and AML in these patients reveals the importance of screening GATA2 in chronic neutropenia associated with monocytopenia because of the frequent hematopoietic transformation, variable clinical expression at onset, and the need for aggressive therapy in patients with poor clinical outcome.

Full Text Available Patients with prolonged neutropenia are at risk for a variety of complications and infections including the development of mucositis and oral ulcers. The changes in oral flora during chemotherapy and its effects on the development of infections of the oral cavity have been studied with inconsistent results. However, there is evidence that supports the colonization of gram negative rods in patients undergoing chemotherapy. In this report, we present two leukemic patients who developed oral ulcers secondary to multi-drug resistant Pseudomonas aeruginosa. It is important to suspect multi-drug resistant gram negative rods in patients with prolonged neutropenia who develop gum infections despite appropriate antibiotic coverage.

Full Text Available Resumo: A doença infecciosa contribui para uma elevada morbilidade e mortalidade no doente oncológico, representando a pneumonia adquirida na comunidade a mais frequente.O desenvolvimento de PAC no doente neoplásico parece advir da modificação de mecanismos de defesa imunitária resultante, quer da patologia maligna, quer do tratamento oncológico. O risco de infecção relacionada com o tipo de neoplasia pode associar-se ao défice de imunidade humoral, celular ou do número de neutrófilos. As doenças hematológicas malignas podem predispor o doente às infecções devido à substituição da medula por células neoplásicas. Consequentemente, estes doentes têm neutropenia funcional, apesar de apresentarem, muitas vezes, um número normal ou aumentado de neutrófilos. Por outro lado, estes doentes podem ter neutropenia como efeito secundário da quimioterapia e/ou radioterapia (neutropenia absoluta.A gravidade da neutropenia foi considerada como principal factor de risco isolado no doente neoplásico, com particular relevância se o número de neutrófilos ≤500cel/mm3.A mortalidade global atribuída à neutropenia febril no doente neoplásico é de 30–50%. Nas últimas décadas, o tratamento das infecções na população oncológica foi direccionado, primariamente, para o manuseamento da neutropenia febril, devido ao facto de o local da infecção não ser determinado em 50–80% dos casos.As guidelines da American Thoracic Society de 2001 utilizavam a neutropenia para identificar os quadros mais graves de PAC nos doentes oncológicos.

Concomitant Use of Topiramate Inducing Neutropenia in a Schizophrenic Male Stabilized on Clozapine

Directory of Open Access Journals (Sweden)

Pravesh Sharma

2016-01-01

Full Text Available This is a case of a 23-year-old African American male with a history of paranoid schizophrenia that developed neutropenia on a clozapine-topiramate therapy. Clozapine had well addressed the patient’s psychotic symptoms, while topiramate was used as a weight-lowering agent. The patient had fairly stable leukocyte counts for eight months on clozapine 300 mg and topiramate 100 mg daily. Doubling the dosage of topiramate led to severe neutropenia after two months. Reviewing the patient’s laboratory reports showed a gradual decline of neutrophils occurring at a lower dosage, followed by a rapid decline after an increased dosage. In this case, we report that not only did topiramate act as the neutropenic agent, but also it might have done so in a dose-dependent manner.

Ha sido relacionado antes con diversas infecciones, principalmente por virus. Informamos de tres pacientes con síndrome hemofagocítico secundario a dengue hemorrágico, confirmado por exámenes específicos de laboratorio, quienes fueron internados en el Hospital Universitario Ramón González Valencia de Bucaramanga, Colombia, durante los últimos dos años. Los tres pacientes fueron escolares que presentaron dengue hemorrágico y manifestaron dolor abdominal intenso, fiebre prolongada, hipotensión y hepatomegalia dolorosa; los exámenes paraclínicos mostraron plaquetopenia, anemia y leucopenia; en la ecografía abdominal se observó colecistitis acalculosa y en todos los aspirados de medula ósea se encontraron histiocitos fagocitando células hemáticas de la serie eritroide, mieloide o plaquetaria. Se definió y clasificó el síndrome hemofagocítico, según la Sociedad Internacional de Histiocitosis, en tres grandes clases, recalcando que los casos informados corresponden a histiocitosis clase II y, más específicamente, al síndrome hemofagocítico secundario. Se mencionan las diversas asociaciones de este síndrome con infecciones, principalmente virales, y otras enfermedades no infecciosas; se hace diferenciacion entre síndrome hemofagocítico familiar o primario y el secundario. Finalmente, se enfatiza que los tres pacientes con este síndrome asociado con dengue hemorrágico tuvieron una evolución atípica durante el curso de su enfermedad; la fiebre prolongada y el dolor abdominal persistente fueron los síntomas más importantes. Los autores recomiendan realizar un aspirado de médula ósea como parte de los estudios para el diagnóstico diferencial de casos atípicos de dengue, especialmente con fiebre prolongada, buscando la posibilidad de un síndrome hemofagocítico secundario.

Full Text Available Abstract Background Several clinical trials have demonstrated the efficacy of fluconazole as empiric antifungal therapy in cancer patients with fever and neutropenia. Our objective was to assess the frequency and resource utilization associated with treatment failure in cancer patients given empiric fluconazole antifungal therapy in routine inpatient care. Methods We performed a retrospective cohort study of cancer patients treated with oral or intravenous fluconazole between 7/97 and 6/01 in a tertiary care hospital. The final study cohort included cancer patients with neutropenia (an absolute neutrophil count below 500 cells/mm3 and fever (a temperature above 38°C or 100.4°F, who were receiving at least 96 hours of parenteral antibacterial therapy prior to initiating fluconazole. Patients' responses to empiric therapy were assessed by reviewing patient charts. Results Among 103 cancer admissions with fever and neutropenia, treatment failure after initiating empiric fluconazole antifungal therapy occurred in 41% (95% confidence interval (CI 31% – 50% of admissions. Patients with a diagnosis of hematological malignancy had increased risk of treatment failure (OR = 4.6, 95% CI 1.5 – 14.8. When treatment failure occurred the mean adjusted increases in length of stay and total costs were 7.4 days (95% CI 3.3 – 11.5 and $18,925 (95% CI 3,289 – 34,563, respectively. Conclusion Treatment failure occurred in more than one-third of neutropenic cancer patients on fluconazole as empiric antifungal treatment for fever in routine clinical treatment. The increase in costs when treatment failure occurs is substantial.

Bladder cancer patients receiving methotrexate, vinblastine, adriamycin and cisplatin (MVAC) chemotherapy are co-administered with dexamethasone as an anti-emetic. We examined whether or not dexamethasone affects the severity and onset day of MVAC-induced severe neutropenia. This was a retrospective study of bladder cancer patients treated with MVAC chemotherapy with or without dexamethasone as an antiemetic at Kanazawa University Hospital during January 2005 - December 2009. Patients were categorized into three groups; no dexamethasone use (Dex (-)), dexamethasone on day 2 (Dex 1 day), and dexamethasone on days 2, 3 and 4 (Dex multiday). We evaluated the incidence of grade 3/4 neutropenia and the day of onset of first severe neutropenic episode during the first course of MVAC chemotherapy. Logistic regression was used to investigate whether co-administration of dexamethasone was a risk factor for severe neutropenia. Episodes of grade 3/4 neutropenia occurred in 3 out of 6 (50.0%), 11 out of 12 (91.7%) and 6 out of 6 (100%) patients in the Dex (-), Dex 1 day, and Dex multiday groups, respectively. The appearance day of first severe neutropenia in the Dex multiday group (13.2 ± 1.0) was significantly accelerated compared to the Dex (-) group (17.7 ± 2.1). Univariate logistic regression analysis revealed that dexamethasone is a risk factor for severe neutropenia (OR 17.0; 95%CI: 1.3-223.1). Co-administration of dexamethasone for anti-emesis brings forward the first appearance of neutropenia, and increases the severity of neutropenia, in bladder cancer patients receiving MVAC chemotherapy.

Malnutrition has been reported in the literature to be adversely associated with outcomes in paediatric malignancies. Our objective in this paper was to evaluate malnutrition as a potential predictor for adverse outcomes in febrile neutropenia associated with haematological malignancies. A prospective observational study was performed in a tertiary care teaching hospital of Kolkata, India. Forty-eight participants, suffering from haematological malignancy, were included. Participants were included if they experienced at least one episode of febrile neutropenia. For children aged malnutrition, while body mass index for age was used in children ≥5 years. A total of 162 episodes of febrile neutropenia were studied. Thirty patients (30/48, 62.5%) included in the study had malnutrition. In bivariate analyses at patient level, there is a strong association between malnutrition and death (odds ratio (OR) 7.286, 95% confidence interval (CI) 0.838-63.345, one-tailed P = 0.044), and life-threatening complications show a moderate trend towards significance (OR 3.333, 95% CI 0.791-14.052, one-tailed P = 0.084). Survival functions were significantly different between malnourished and non-malnourished children (log rank test χ(2)  = 4.609, degree of freedom = 1, P = 0.032). Wasting was associated with life-threatening complications in children aged malnutrition was not. Malnutrition may be a potential predictor of mortality in febrile neutropenia. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Results. 115 febrile episodes in 102 patients were identified. Regression analysis yielded prolonged fever >7 days prior to admission (OR 2.43; 95% CI, 0.77–7.74, isolation of a pathogen on cultures (OR 2.69; 95% CI, 1.04–6.98, and nadir absolute neutrophil count (ANC 7 days prior to admission, positive pathogen on cultures, and nadir ANC < 100 during admission predicted severe outcomes, whereas G-CSF use and complete antibiotic therapy were associated with better outcomes. These prognostic variables might be useful in identifying patients that need more intensive treatment and monitoring.

Full Text Available Estudo prospectivo, tipo coorte que visou identificar a influência da sobrecarga de trabalho da Enfermagem na ocorrência de incidentes sem lesão e eventos adversos em 399 pacientes internados em Unidades de Terapia Intensiva (UTI. Para coleta de dados, foi aplicado um questionário estruturado e feita análise de prontuários. Nessas admissões, aproximadamente 78% dos incidentes sem lesão e eventos adversos em pacientes foram relacionados à esfera da Enfermagem. Essas ocorrências foram atribuídas à sobrecarga de trabalho, aumentaram o número de dias de internação e o risco de óbito dos pacientes estudados. É fundamental que os gerentes de enfermagem atuem no processo de gestão de pessoas no âmbito hospitalar, evitando a sobrecarga de trabalho e proporcionando, consequentemente, aumento da segurança do paciente.

La mayoría de las infecciones se presentaron en pacientes con hemopatías malignas, de los cuales una gran parte tuvo neutropenia severa. En los episodios infecciosos las bacterias gramnegativas fueron las más frecuentes, seguidas de las grampositivas y los hongos, estos últimos siempre asociados con infecciones bacterianas. El estafilococo coagulasa negativo fue el microorganismo de mayor incidencia. Los pacientes que tuvieron colocado el catéter venoso central en región femoral tuvieron mayor riesgo de presentar bacteriemia por bacilos gramnegativos.A cross-sectional study was performed at the Pediatric Department of the Institute of Hematology and Immunology from December 2006 to March 2009. There were 36 patients who had 60 infections with microbiological documentation, which represented 29 % of the total. Most infections occurred in patients with hematological malignancies, of which a large portion had severe neutropenia. In infectious episodes Gram-negative bacteria was the most frequent, followed by Gram positive and fungi, this latter was always associated with bacterial infections. Coagulase negative staphylococcus was the organism with the highest incidence. Patients who had central venous catheter placed in the femoral region had a higher risk of negative bacilli bacteremia.

We report a case of familial, chronic, benign neutropenia in a 17-year-old female showing (1) the spontaneous expression of a heritable rare fragile site at 16q22 and (2) a deletion at the same region. The del(16)(q22), which most likely originated from the fragile site, was the main clonal abnormality detected in the patient's bone marrow cells, whereas a few cells with either del(16)(q22) or fra(16)(q22) were seen in the patient's peripheral blood. Interestingly, the del(16q) was also detected in the patient's uncultured cells, as demonstrated by FISH, excluding an in vitro origin of the del(16q) during culture. The bone marrow was hypocellular with decreased neutrophils and their precursors. Absolute neutrophil counts ranged from (0.62 to 1.24) x 10(9)/L with a median value of 1.02 x 10(9)/L. The patient had a more severe neutropenia than her mother, which correlated with the presence of more cells with del(16q) in the marrow. The patient's mother, who was also diagnosed with neutropenia, revealed only a few cells with the rare fra(16)(q22) in her peripheral blood cells, whereas her bone marrow showed cells with both fra(16)(q22) and del(16)(q22), although the del(16q) was present in only 2/20 cells. Some possible candidate genes contributing to the pathogenesis of the neutropenia are discussed. Chromosome abnormalities involving the 16q22 breakpoint have been observed in myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). In this patient, the del(16)(q22) risk factor is unknown for subsequent development of MDS or AML. Another point to consider is the need to determine the origin of a chromosome abnormality, particularly when the clinical picture does not fit the chromosome findings. Although, the observation of a constitutional structural abnormality in a mosaic form is an extremely rare event, it is somewhat different in the case of a fragile site expression, which can, as in this case, be present in some cells and not in others.

Managing febrile neutropenia in adult cancer patients: an integrative review of the literature

Directory of Open Access Journals (Sweden)

Juliana Nunes Ferreira

Full Text Available ABSTRACT Objective: To analyze the interventions performed by health professionals with a view to managing chemotherapy-induced febrile neutropenia. Method: Integrative literature review, the sample of 12 primary articles was selected from the following databases: LILACS, SciELO, BVS, PubMed, CINAHL and Web of Science. Results: There was a prevalence of studies, realized by doctors, focused on pharmacological treatment and on the association of methods for greater diagnostic accuracy of febrile neutropenia. A study was found on pharmaceutical management regarding antibiotic dosing efficacy and a study indicating that nurses could contribute to the identification of elderly patients who would benefit from prophylactic use of growth factor. Conclusion: There was a shortage of studies involving the participation of other health professionals, besides the doctors, and a knowledge gap regarding interprofessional practice in the management of interventions specific to their area of specialism, joint interventions and non-pharmacological interventions.

To assess cost-effectiveness of antifungal treatment on patients with persistent fever neutropenia: empiric antifungal therapy (EAT) vs. anticipated antifungal therapy (AAT). A decision model was performed to evaluate the cost-effectiveness of antifungal treatment strategies in patients with febrile neutropenia not responding to a broad spectrum antibiotic treatment. The strategies included were: 1) EAT with amphotericin B deoxycholate; 2) EAT with liposomal amphotericin B; 3) EAT with caspofungin; and 4) AAT with voriconazole and amphotericin B deoxycholate or liposomal amphotericin B or caspofungin in patients who initiate treatment despite having negative CT scan and galactomannan or fail to voriconazole. Effectiveness was measured as the number of deaths averted. Cost-effectiveness and incremental cost-effectiveness ratios were calculated. Deterministic and probabilistic sensitivity analyzes were performed. EAT with Amphotericin B deoxycholate was the least expensive and least effective strategy. The EAT with caspofungin was the most effective. The cost per death averted for caspofungin when compared with amphotericin B deoxycholate was $17,011,073.83, which would indicate that this strategy would be cost-effective for the country if the willingness to pay per death averted is equal to or greater than this value. EAT with liposomal amphotericin B and AAT with voriconazole were dominated by AET with caspofungin, which is less costly and more effective. EAT with caspofungin would be cost-effective for Colombia if the threshold per death averted is greater to $18.000.000. If the threshold is lesser the EAT with amphotericin B deoxycholate would be the election. Copyright © 2012 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Prevention of chemotherapy-induced neutropenia with pegfilgrastim: pharmacokinetics and patient outcomes.

Science.gov (United States)

Yang, Bing-Bing; Savin, Michael A; Green, Michael

2012-01-01

Patients receiving cytotoxic chemotherapy are at risk for developing chemotherapy-induced neutropenia (CIN). Filgrastim, a recombinant granulocyte colony-stimulating factor (G-CSF) that stimulates the proliferation, differentiation and function of neutrophils, is approved for the prevention of CIN. To eliminate the burden of daily filgrastim injection, pegfilgrastim, a long-acting form of filgrastim, was developed by covalently attaching a 20-kDa polyethylene glycol molecule to filgrastim to increase molecular size and thus reduce renal elimination. Consequently, neutrophil-mediated clearance is the primary mechanism for pegfilgrastim elimination. Therefore, after a single pegfilgrastim injection following chemotherapy treatment, pegfilgrastim concentration is sustained during neutropenia and decreases with neutrophil recovery. Pegfilgrastim has received marketing authorization approval from many regions to reduce the incidence of CIN based on the similar efficacy and safety of a single injection of 6 mg of pegfilgrastim administered once per chemotherapy cycle and 10 to 11 daily injections of filgrastim at 5 µg/kg. The efficient self-regulating clearance of pegfilgrastim allows administration once per chemotherapy cycle, thereby providing a more convenient treatment regimen than filgrastim. Copyright © 2012 S.

Full Text Available Gfi1 is a key molecule in hematopoietic lineage development and mutations in GFI1 cause severe congenital neutropenia (SCN. Neutropenia is associated with low bone mass, but the underlying mechanisms are poorly characterized. Using Gfi1 knock-out mice (Gfi1-ko/ko as SCN model, we studied the relationship between neutropenia and bone mass upon different pathogen load conditions. Our analysis reveals that Gfi1-ko/ko mice kept under strict specific pathogen free (SPF conditions demonstrate normal bone mass and survival. However, Gfi1-ko/ko mice with early (nonSPF or late (SPF+nonSPF pathogen exposure develop low bone mass. Gfi1-ko/ko mice demonstrate a striking rise of systemic inflammatory markers according to elevated pathogen exposure and reduced bone mass. Elevated inflammatory cytokines include for instance Il-1b, Il-6, and Tnf-alpha that regulate osteoclast development. We conclude that low bone mass, due to low neutrophil counts, is caused by the degree of systemic inflammation promoting osteoclastogenesis.

Objective: To explore the efficacy and safety of polyethylene glycal recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patiens with breast cancer. Methods: There were two parts in the present phase Ⅳ clinical study. One was a randomized, controlled clinical study. Patients in this study received PEG-rhG-CSF or rhG-CSF in the first cycle and followed with both PEG-rhG-CSF in the rest of 3 cycles. The other one was a single arm study. Patients who developed Ⅲ/Ⅳ grade neutropenia in the screening cycle received PEG-rhG-CSF in the rest of 3 cycles chemotherapy. Results: In the first cycle of randomized, controlled study, the incidence of Ⅳ grade neutropenia are 31.48% and 35.58% respectively in PEG-rhG-CSF and rhG-CSF group, with no statistically significant differences ( P =0.527 6). The duration of Ⅳ grade neutropenia respectively are 2.22±1.58 and 3.00±1.59 days, with a statistically significant difference ( P =0.016 6). In the single arm study, the incidence of Ⅳ grade neutropenia was 57.76% in screening cycle. And the incidence decreased to 16.35%, 10%, and 8.57% in the followed 3 cycle after the use of PEG-rhG-CSF. The incidence of adverse effects was 5.06%, and the major adverse effect was bone pain which with an incidence of 2.8%. Conclusion: The fixed 6mg dose of PEG-rhG-CSF can effectively prevent neutropenia in patients with breast cancer in multicycle chemotherapy and it has a low incidence of adverse events and mild adverse reaction.

Full Text Available Abstract Background Febrile neutropenia carries a high risk of sepsis complications, and the identification of biomarkers capable to identify high risk patients is a great challenge. Angiopoietins (Ang - are cytokines involved in the control microvascular permeability. It is accepted that Ang-1 expression maintains endothelial barrier integrity, and that Ang-2 acts as an antagonizing cytokine with barrier-disrupting functions in inflammatory situations. Ang-2 levels have been recently correlated with sepsis mortality in intensive care units. Methods We prospectively evaluated concentrations of Ang-1 and Ang-2 at different time-points during febrile neutropenia, and explored the diagnostic accuracy of these mediators as potential predictors of poor outcome in this clinical setting before the development of sepsis complications. Results Patients that evolved with septic shock (n = 10 presented higher levels of Ang-2 measured 48 hours after fever onset, and of the Ang-2/Ang-1 ratio at the time of fever onset compared to patients with non-complicated sepsis (n = 31. These levels correlated with sepsis severity scores. Conclusions Our data suggest that imbalances in the concentrations of Ang-1 and Ang-2 are independent and early markers of the risk of developing septic shock and of sepsis mortality in febrile neutropenia, and larger studies are warranted to validate their clinical usefulness. Therapeutic strategies that manipulate this Ang-2/Ang-1 imbalance can potentially offer new and promising treatments for sepsis in febrile neutropenia.

Recently, there has been a controversial discussion about the prognostic value of chemotherapy-induced neutropenia (CIN) in colorectal cancer patients. Thus, a meta-analysis was conducted to determine the relationship between CIN and the prognosis of colorectal cancer patients. We searched the PubMed, EMBASE, and Cochrane library databases to identify studies evaluating the association between CIN and colorectal cancer prognosis. Pooled random/fixed effect models were used to calculate pooled hazard ratios (HRs) and 95% confidence intervals (CIs) to assess the association. Eight studies were selected for the meta-analysis, for a total of 2,745 patients. There was significant improved survival among colorectal cancer patients with CIN (HR = 0.62, 95% CI = 0.47-0.76). However, significant heterogeneity was found (p = 0.000, Ι 2  = 75.0%). Through subgroup analysis, we could greatly eliminate the heterogeneity and found that neutropenia was associated with better survival in stage IV colorectal cancer patients, no matter the HR calculated by overall survival (OS) or progression-free survival (PFS). Meanwhile, the prognostic value of neutropenia in stage II/III colorectal cancer can be found when the HR is calculated by disease-free survival (DFS). Additionally, we observed significant differences after stratification according to various tumor stages, endpoints, and the use of G-CSF. Our results which, based on a cohort study, indicate that CIN is associated with improved survival in patients with colorectal cancer. However, further randomized controlled trials are warranted.

The objective of this study was to determine whether severe neutropenia on the day of port-a-catheter (PORT) insertion was a risk factor for catheter-associated infection (CAI) in children with acute lymphoblastic leukemia (ALL). This was a retrospective study of children with ALL who had a PORT insertion between January 2005 and August 2008. Early (≤ 30 days) and late (>30 days) postprocedure complications were reviewed. The length of follow-up ranged between 7 months and 42 months. In total, 192 PORTs were inserted in 179 children. There were 43 CAIs (22%), and the infection rate was 0.35 per 1000 catheter-days. The CAI rate (15%) in children who had severe neutropenia on the day of the procedure did not differ statistically from the CAI rate (24%) in children who did not have severe neutropenia (P = .137). Conversely, patients with severe neutropenia who had a CAI were more likely to have their PORT removed (P = .019). The most common organisms to cause catheter removal were coagulase-negative Staphylococcus and Staphylococcus aureus. Patients with high-risk ALL had a statistically significant higher incidence of late CAI than patients with standard-risk ALL (P = .012). Age (P = .272), positive blood culture preprocedure (P = 1.0), and dexamethasone use (P = .201) were not risk factors for CAI. Patients who had an early CAI did not have a greater chance of having a late CAI. The catheter infection-free survival rate at 1 year was 88.6%. The current results indicated that severe neutropenia on the day of PORT insertion does not increase the risk of CAI in children with ALL. © 2010 American Cancer Society.

Neutropenias (NPs), being acute and often transient, or chronic, range from life-threatening conditions with very low absolute neutrophil blood counts (ANC) to disorders characterized by only mild NP and of no obvious significance for health. Many are caused by genetic variations/mutations, e.g. the benign familial NP and the chronic severe NPs (e.g. Kostmann disease). Some of the latter are associated with various bodily malformations. Many of the mild-to-moderate NPs are signs of underlying disorders that need specialized treatments (e.g. HIV, hepatitis, autoimmune disorders, the large granular lymphocyte syndrome). We provide here means for the evaluation of a previously unknown NP, suggest a triage and treatments.

This randomized, dual-center study compared the efficacy and safety of piperacillin-tazobactam (PTZ) and imipenem-cilastatin (IMP) in hematopoietic stem cell transplantation (HSCT) recipients with febrile neutropenia. HSCT recipients with febrile neutropenia were randomized into two groups receiving either PTZ or IMP as initial empiric antibiotic. Endpoints were defervescence rate after empiric antibiotic for 48 h, success at end of therapy, and side effects. Defervescence within 48 h after empiric antibiotic was observed in 46 patients with PTZ (75.4%) and 59 patients with IMP (95.2%) (p = 0.002). Ten patients (10/46) in the PTZ group and two patients (2/59) in the IMP group switched empiric antibiotics due to recurrent fever (p = 0.005). Success of initial antibiotic with modification was achieved in 34 patients with PTZ (55.7%) and 53 patients with IMP (85.5%) at the end of therapy (p = 0.001). To treat the bacteremia, seven of 10 patients in the PTZ group and one of eight patients in the IMP group needed to switch the empiric antibiotic (p = 0.025). Compared with PTZ, IMP had more gastrointestinal adverse events (p = 0.045). This study demonstrates that IMP had better efficacy than PTZ as an empiric antibiotic for febrile neutropenia in the HSCT setting, but with more gastrointestinal side reactions. © 2015 John Wiley & Sons A/S.

We report a male with history of recurrent infections (recurrent oral aphtous disease [ROAD], middle ear infections and pharyngo amigdalitis) every 3 weeks since he was 7 months old. At the age of 3 years cyclic neutropenia was diagnosed with cyclic fall in the total neutrophil count in blood smear every 21 days and prophylactic antimicrobial therapy was indicated. Episodic events every 3 weeks of acute asthma and allergic rhinitis were detected at the age of 6 years old and specific immunotherapy to Bermuda grass was given during 3 years with markedly improvement in his allergic condition but not in the ROAD. He came back until the age of 16 with episodic acute asthma and ROAD. The total neutrophil count failed to 0 every 21 days and surprisingly the total eosinophil count increased up to 2,000 at the same time, with elevation of serum IgE (412 Ul/mL). Specific immunotherapy to D.pt. and Aller.a. and therapy with timomodulin was indicated. After 3 months we observed clinical improvement in the asthmatic condition and the ROAD disappeared, but the total neutrophil count did not improve. We present this case as a rare association between 2 diseases with probably no etiological relationship but may be physiopatological that could help to understand more the pathogenesis of asthma.

Three familial cases of each of severe congenital neutropenia (SCN) and cyclic neutropenia (CN) in addition to 3 sporadic cases of SCN were analyzed for neutrophil elastase (Ela2) gene mutation. The contents of the neutrophil-specific granule proteins cathelicidin antimicrobial peptide and neutrophil gelatinase-associated lipocalin were also analyzed in SCN. Genomic DNA was extracted from the patients' peripheral blood or bone marrow, and the coding sequence of the Ela2 gene was amplified by polymerase chain reaction and subjected to direct sequencing. The contents of antimicrobial peptides were analyzed by flow cytometry. Three cases of familial SCN (P13L, R52P, and S97L), 2 of familial CN (W212stop and P110L), and 1 of sporadic SCN (V72M) were shown to have heterozygous mutations in the Ela2 gene. W212stop found in a familial CN case was a novel mutation of Ela2. Prophylactic treatment for growth factors or antibiotic prophylaxis against bacterial infection was useful for lowering the frequency of infectious episodes. Adult patients tended to have less frequent infections compared with minors in the same family. The contents of both cathelicidin antimicrobial peptide and neutrophil gelatinase-associated lipocalin were significantly reduced in SCN compared with healthy controls. Prophylaxis by growth factor or antibiotics is useful for decreasing risks of bacterial infections in SCN and CN. Adults were likely to have less frequent infections than children in familial cases of SCN and CN with the same mutation of Ela2.

To determine if severe neutropenia at the time of chest port insertion is a risk factor for port removal and central catheter-associated bloodstream infection (CCABSI) in pediatric patients. From May 2007 to June 2015, 183 consecutive patients (mean age, 9.9 y; range, 0.75-21 y) had a port inserted at a single tertiary pediatric center. Seventy-two had severe neutropenia at the time of port insertion (absolute neutrophil count [ANC] range, 0-500/mm 3 ; mean, 185/mm 3 ). Follow-up until port removal or death and CCABSI events were recorded. Within the first 30 days, similar incidences of CCABSI (12.5% of patients with severe neutropenia [n = 9] vs 4.5% of patients without [n = 5]), port removal for infection (2.8% [n = 2] vs 2.7% [n = 3]), and local port infection (2.8% [n = 2] vs 0.9% [n = 1]) were observed in both groups (P > .05), but the rate of CCABSI per 1,000 catheter-days was higher for patients with severe neutropenia (P = .045). Overall, similar incidences of CCABSI (18.1% [n = 13] vs 16.2% [n = 18]), port removal for infection (2.8% [n = 2] vs 7.2% [n = 8]), local port infection (2.8% [n = 2] vs 2.7% [n = 3]), and CCABSIs per 1,000 catheter-days (0.332 vs 0.400) were observed in both groups (P > .05). Port placement in patients with severe neutropenia can be performed without an increased incidence of port removal for infection. The majority of CCABSIs were successfully treated without port removal. Copyright © 2016 SIR. Published by Elsevier Inc. All rights reserved.

A Patient Risk Model of Chemotherapy-Induced Febrile Neutropenia: Lessons Learned From the ANC Study Group.

Science.gov (United States)

Lyman, Gary H; Poniewierski, Marek S

2017-12-01

Neutropenia and its complications, including febrile neutropenia (FN), represent major toxicities associated with cancer chemotherapy, resulting in considerable morbidity, mortality, and costs. The myeloid growth factors such as granulocyte colony-stimulating factor (G-CSF) have been shown to reduce the risk of neutropenia complications while enabling safe and effective chemotherapy dose intensity. Concerns about the high costs of these agents along with limited physician adherence to clinical practice guidelines, resulting in both overuse and underuse, has stimulated interest in models for individual patient risk assessment to guide appropriate use of G-CSF. In a model developed and validated by the ANC Study Group, half of patients were classified as high risk and half as low risk based on patient-, disease-, and treatment-related factors. This model has been further validated in an independent patient population. Physician-assessed risk of FN, as well as the decision to use prophylactic CSF, has been shown to correlate poorly with the FN risk estimated by the model. Additional modeling efforts in both adults and children receiving cancer treatment have been reported. Identification of patients at a high individual risk for FN and its consequences may offer the potential for optimal chemotherapy delivery and patient outcomes. Likewise, identification of patients at low risk for neutropenic events may reduce costs when such supportive care is not warranted. This article reviews and summarizes FN modeling studies and the opportunities for personalizing supportive care in patients receiving chemotherapy.

Full Text Available Neutropenia and infections are the most restrictive side effects during chemotherapy application. The granulocytic colonies stimulating factor activates the neutrophils, shortens the neutropenic period and can be effective against the potential risk of infection. The purpose of this study was to evaluate the efficacy and safety of LeukoCIM® (CIMAB, Havana. A retrospective observational study was carried out with data from the patients with neutropenic episodes enrolled in the open-label, non-randomized, multicenter, phase IV clinical trial. These patients were from Gustavo Aldereguía Lima hospital. They had been evaluated for one year. Demographic information, clinical data and side effects were analyzed. As prophylaxis indication LeukoCIM® was administrated 24-72 h after the last chemotherapy dose and as treatment when neutropenia was diagnosed. In both cases, a daily single 300 µg dose was administrated subcutaneously. The application of the next chemotherapy cycle on time was the main variable of response and the product safety was assessed by measuring the side effects. Forty seven patients with 95 neutropenic episodes were enrolled. The 82.1 % of episodes received their next chemotherapy cycle on time. The most frequent side effects were: bone pain and fever (11.2 % respectively, hyperuricemia (9.2 %, leukocytosis and neutrophilia (7.1 % and increased LDH (6.1 %. LeukoCIM® was effective in patients receiving chemotherapy, because it accelerated neutrophil recovery, decreased the incidence of febrile neutropenia and improved delivery of protocol doses of chemotherapy on time. Additionally, this product was considered safe for the studied patients since just known adverse events were reported.

We studied a group of individuals with elevated urinary excretion of 3-methylglutaconic acid, neutropenia that can develop into leukemia, a neurological phenotype ranging from nonprogressive intellectual disability to a prenatal encephalopathy with progressive brain atrophy, movement disorder, cataracts, and early death. Exome sequencing of two unrelated individuals and subsequent Sanger sequencing of 16 individuals with an overlapping phenotype identified a total of 14 rare, predicted deleterious alleles in CLPB in 14 individuals from 9 unrelated families. CLPB encodes caseinolytic peptidase B homolog ClpB, a member of the AAA+ protein family. To evaluate the relevance of CLPB in the pathogenesis of this syndrome, we developed a zebrafish model and an in vitro assay to measure ATPase activity. Suppression of clpb in zebrafish embryos induced a central nervous system phenotype that was consistent with cerebellar and cerebral atrophy that could be rescued by wild-type, but not mutant, human CLPB mRNA. Consistent with these data, the loss-of-function effect of one of the identified variants (c.1222A>G [p.Arg408Gly]) was supported further by in vitro evidence with the mutant peptides abolishing ATPase function. Additionally, we show that CLPB interacts biochemically with ATP2A2, known to be involved in apoptotic processes in severe congenital neutropenia (SCN) 3 (Kostmann disease [caused by HAX1 mutations]). Taken together, mutations in CLPB define a syndrome with intellectual disability, congenital neutropenia, progressive brain atrophy, movement disorder, cataracts, and 3-methylglutaconic aciduria.

Objective: To evaluate the association between serum albumin and risk of post chemotherapy febrile neutropenia. Study Design: Cross sectional study. Place and Duration of Study: Department of oncology, Liaquat National Hospital, from 1st Jan 2015 to 31st Dec 2016. Material and Method: One hundred and sixty-six biopsy proven cancer patients with Eastern cooperative oncology group (ECOG) performance status <2 and without significant co-morbidities received first cycle of chemotherapy during two years study period. Different chemotherapies with moderate to severe risk of FN were used. Patient's pre-treatment serum albumin was measured and patients followed for occurrence of FN. Association between serum albumin and post chemotherapy FN was analyzed. Results: Data of 166 patients was available for final analysis. Post chemotherapy FN was observed in 19.9% (33/166) patients. Pre-chemotherapy serum albumin level was <3.5 mg/dl in (35/166) 21.1% of patients, out of which (15/35) 42.9% developed FN. Serum albumin (p=0.0005) was highly significantly associated with a risk of FN. On analysis of other factors age, gender, body surface area (BSA) and pre-chemotherapy hemoglobin level were not significantly associated with a risk of FN while body mass index (p=0.0005) was found to be associated with risk of FN. Conclusion: Pre-chemotherapy serum albumin levels were found to be statistically significant predictor of postchemotherapy febrile neutropenia.

Many bloodstream infections (BSIs) occurring in patients with febrile neutropenia following cytotoxic chemotherapy are due to translocation of intestinal microbiota. However, these infections meet the National Healthcare Safety Network (NHSN) definition of central line-associated BSIs (CLABSIs). We sought to determine the differences in the microbiology of NHSN-defined CLABSIs in patients with and without neutropenia and, using these data, to propose a modification of the CLABSI definition. Retrospective review. Two large university hospitals over 18 months. All hospital-acquired BSIs occurring in patients with central venous catheters in place were classified using the NHSN CLABSI definition. Patients with postchemotherapy neutropenia (500 neutrophils/mm(3) or lower) at the time of blood culture were considered neutropenic. Pathogens overrepresented in the neutropenic group were identified to inform development of a modified CLABSI definition. Organisms that were more commonly observed in the neutropenic group compared with the nonneutropenic group included Escherichia coli (22.7% vs 2.5%; P definition (removing BSI with enterococci, streptococci, or E. coli) excluded 33 of 66 neutropenic CLABSIs and decreased the CLABSI rate in one study hospital with large transplant and oncology populations from 2.12 to 1.79 cases per 1,000 line-days. Common gastrointestinal organisms were more common in the neutropenia group, suggesting that many BSIs meeting the NHSN criteria for CLABSI in the setting of neutropenia may represent translocation of gut organisms. These findings support modification of the NHSN CLABSI definition.

Hematologic toxicities of cancer chemotherapy are common and often limit the ability to provide treatment in a timely and dose-intensive manner. These limitations may be of utmost importance in the adjuvant and curative intent settings. Hematologic toxicities may result in febrile neutropenia, infections, fatigue, and bleeding, all of which may lead to additional complications and prolonged hospitalization. The older cancer patient and patients with significant comorbidities may be at highest...

Full Text Available Background: Chemotherapy for breast cancer often deteriorates quality of life, augments fatigue, and induces neutropenia. Mistletoe preparations are frequently used by cancer patients in Central Europe. Physicians have reported better quality of life in breast cancer patients additionally treated with mistletoe preparations during chemotherapy. Mistletoe preparations also have immunostimulant properties and might therefore have protective effects against chemotherapy-induced neutropenia.Patients and Methods: We conducted a prospective randomized open label pilot study with 95 patients randomized into three groups. Two groups received Iscador® M special (IMS or a different mistletoe preparation, respectively, additionally to chemotherapy with six cycles of cyclophosphamide, adriamycin, and 5-fluoro-uracil (CAF. A control group received CAF with no additional therapy. Here we report the comparison IMS (n = 30 vs. control (n = 31. Quality of life including fatigue was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30. Neutropenia was defined as neutrophil counts <1,000/µl and assessed at baseline and one day before each CAF cycle.Results: In the descriptive analysis all 15 scores of the EORTC-QLQ-C30 showed better quality of life in the IMS group compared to the control group. In 12 scores the differences were significant (p < 0.02 and nine scores showed a clinically relevant and significant difference of at least 5 points. Neutropenia occurred in 3/30 IMS patients and in 8/31 control patients (p = 0.182.Conclusions: This pilot study showed an improvement of quality of life by treating breast cancer patients with IMS additionally to CAF. CAF-induced neutropenia showed a trend to lower frequency in the IMS group.

Full Text Available Introduction: prophylaxis with granulocyte colony-stimulating factors (G-CSF is indicated for reduction in the duration of neutropenia and the incidence of febrile neutropenia in patients treated with cytotoxic chemotherapy for malignancy.
Objective: to evaluate the budgetary impact for the Italian NHS.
Design: a decision-analytic model has been developed to analyze the budget impact from the national health care system perspective. Costs include direct healthcare costs to the public payer of G-CSFs as well as their administration costs and costs of FN-related events. The comparison has been done using prophylaxis with G‑CSF (filgrastim for 11 days, pegfilgrastim, lenograstim for 11 days and antibiotics.
Patients and participants: The population of interest for the analysis were patients with breast cancer in stage II and III and patients with non-Hodgkin’s lymphoma (NHL.
Main outcome measures and results: for all the three patients group (NHL, Breast II and III, and for all the chemotherapy regimens (CHOP 21 and R-CHOP 21 for NHL, AC-T, TAC and TC for Breast stage II and III the budget impact analyses shows a cost reduction for the Italian NHS, as a result of an increase of the use of pegfilgrastim.
Conclusions: in Italy, a treatment strategy including pegfilgrastim as either primary or secondary prophylaxis provides value for money.

Se presenta una paciente de 4 años con diagnóstico de leucemia linfoide aguda, quien, luego de la quimioterapia, desarrolló neutropenia febril y diarrea. Recibió tratamiento antibiótico y antimicótico de amplio espectro. Se aisló Candida albicans y se observaron trofozoítos de Entamoeba histolytica en la materia fecal. La paciente desarrolló candidiosis crónica diseminada que fue tratada con anfotericina B y, posteriormente, con fluconazol. Se ilustra la imagen tomográfica conocida como 'ojo de buey' y su correspondiente estudio histopatológico. Candida spp. es la levadura más común en pacientes inmunosuprimidos con tumores hematológicos que reciben quimioterapia. La candidiosis diseminada que se presenta en estos pacientes persiste y se hace evidente clínicamente una vez se resuelve la neutropenia; se denomina candidiosis crónica diseminada. En la paciente se presentaron varios factores de riesgo, como el tratamiento previo con antibióticos de amplio espectro, la colonización del tracto gastrointestinal por Candida y la neutropenia prolongada. El diagnóstico por imagen se hace principalmente por ecografía, tomografía axial computarizada y resonancia magnética.

2003-01-01

Full Text Available BACKGROUND: The empirical use of antibiotic treatments is widely accepted as a means to treat cancer patients in chemotherapy who have fever and neutropenia. Intravenous monotherapy, with broad spectrum antibiotics, of patients with a high risk of complications is a possible alternative. METHODS: We conducted a prospective open-label, randomized study of patients with lymphoma or leukemia who had fever and neutropenia during chemotherapy. Patients received either monotherapy with ticarcillin/clavulanic acid (T or ceftriaxone plus amikacin (C+A. RESULTS: Seventy patients who presented 136 episodes were evaluated, 68 in each arm of the study. The mean neutrophil counts at admission were 217cells/mm³ (T and 201cells/mm³ (C+A. The mean duration of neutropenia was 8.7 days (T and 7.6 days (C+A. Treatment was successful without the need for modifications in 71% of the episodes in the T group and 81% in the C+A group (p=0.23. Treatment was considered to have failed because of death in two episodes (3% in the T group and three episodes (4% in the C+A group, and because of a change in the drug applied in one episode in the T group and two episodes in the C+A group. Overall success was 96% (T and 93% (C+A. Adverse events that occurred in group T were not related to the drugs used in this study. CONCLUSION: In pediatric and adolescent patients with leukemia or lymphoma, who presented with fever and neutropenia, during chemotherapy, ticarcillin/clavulanic acid was as successful as the combination of ceftriaxone plus amikacin. It should be considered an appropriate option for this group of patients at high risk for infections.

Febrile neutropenia remains a frequent complication in onco-hematological patients, and changes in the circulating level of inflammatory molecules (IM) may precede the occurrence of fever. The present observational prospective study was carried out to evaluate the behavior of plasma tumor necrosis factor alpha (TNF-α), soluble TNF-α I and II receptors (sTNFRI and sTNFRII), monocyte chemoattractant protein-1 [MCP-1 or chemokine (c-c motif) ligand 2 (CCL2)], macrophage inflammatory protein-1α (MIP-1α or CCL3), eotaxin (CCL11), interleukin-8 (IL-8 or CXCL8), and interferon-inducible protein-10 (IP-10 or CXCL10) in 32 episodes of neutropenia in 26 onco-hematological patients. IM were tested on enrollment and 24-48 h before the onset of fever and within 24 h of the first occurrence of fever. Eight of 32 episodes of neutropenia did not present fever (control group) and the patients underwent IM tests on three different occasions. sTNFRI levels, measured a median of 11 h (1-15) before the onset of fever, were significantly higher in patients presenting fever during follow-up compared to controls (P = 0.02). Similar results were observed for sTNFRI and CCL2 levels (P = 0.04 for both) in non-transplanted patients. A cut-off of 1514 pg/mL for sTNFRI was able to discriminate between neutropenic patients with or without fever during follow-up, with 65% sensitivity, 87% specificity, and 93% positive predictive value. Measurement of the levels of plasma sTNFRI can be used to predict the occurrence of fever in neutropenic patients.

The time for the neutrophil count to recover after subcutaneous injection of filgrastim BS1 or lenograstim was studied in patients suffering from neutropenia following preoperative combined chemotherapy using docetaxel, nedaplatin, or cisplatin (in divided doses for 5 days)and 5-fluorouracil for oral cancer. 1. There was no significant difference in the minimum leukocyte and neutrophil counts after chemotherapy. 2. There was no significant difference in the maximum leukocyte and neutrophil counts after chemotherapy. 3. Time for leukocytes to recover from their minimum count(>4,000/mm3)or for neutrophils to recover from their minimum count(>2,000/mm3)and the number of days on which treatment was administered tended to be shorter in the filgrastim BS1 group. Thus, it was concluded that filgrastim BS1 is just as effective as other prior G-CSF agents in treating patients suffering from neutropenia following chemotherapy(TPF therapy).

Efficacy of therapeutic strategies relative to patient- and family-centered outcomes in pediatric oncology must be assessed. We sought to identify outcomes important to children with acute myeloid leukemia and their families related to inpatient versus at-home management of neutropenia. We conducted qualitative interviews with 32 children ≥8 years old and 54 parents. Analysis revealed the impact of neutropenia management strategy on siblings, parent anxiety, and child sleep quality as being outcomes of concern across respondents. These themes were used to inform the design of a questionnaire that is currently being used in a prospective, multiinstitutional comparative effectiveness trial. © 2017 Wiley Periodicals, Inc.

Full Text Available We performed a prospective study in patients with chemotherapy induced febrile neutropenia to investigate the diagnostic value of low-dose computed tomography compared to standard chest radiography. The aim was to compare both modalities for detection of pulmonary infections and to explore performance of low-dose computed tomography for early detection of invasive fungal disease. The low-dose computed tomography remained blinded during the study. A consensus diagnosis of the fever episode made by an expert panel was used as reference standard. We included 67 consecutive patients on the first day of febrile neutropenia. According to the consensus diagnosis 11 patients (16.4% had pulmonary infections. Sensitivity, specificity, positive predictive value and negative predictive value were 36%, 93%, 50% and 88% for radiography, and 73%, 91%, 62% and 94% for low-dose computed tomography, respectively. An uncorrected McNemar showed no statistical difference (p = 0.197. Mean radiation dose for low-dose computed tomography was 0.24 mSv. Four out of 5 included patients diagnosed with invasive fungal disease had radiographic abnormalities suspect for invasive fungal disease on the low-dose computed tomography scan made on day 1 of fever, compared to none of the chest radiographs. We conclude that chest radiography has little value in the initial assessment of febrile neutropenia on day 1 for detection of pulmonary abnormalities. Low-dose computed tomography improves detection of pulmonary infiltrates and seems capable of detecting invasive fungal disease at a very early stage with a low radiation dose.

The Importance of Serum Cytokine Levels in Febrile Neutropenia

Directory of Open Access Journals (Sweden)

Nuray Buyukberber

2003-02-01

Full Text Available The most important evaluation of the neutropenic patients is to determine the risk group. The desired approach to patients with low risks should be either not to hospitalize or to hospitalize for a short period of time which both decreases the cost and exposure to the resistant flora. The early diagnosis of sepsis in patients with high risk may be life saving. Recently, the determination of low and high-risk groups only by the clinical variables is not found to be a reliable method. The laboratory parameters supported by the clinical variables may be more practical. The determination of serum cytokines levels in febrile neutropenia may be helpful for the early risk diagnosis, new treatment approaches, and prognosis.

To find the in-vitro sensitivity data and clinical response in order to determine the changes required in empiric antibiotic therapy for management of febrile neutropenia in paediatric patients undergoing peripheral blood stem cell transplantation. All patients were treated according to institutional protocol for febrile neutropenia. Empirical antibiotics include Ceftriaxone and Amikacin. In non-responders, changes made included Imipenem and Amikacin, Piperacillin Tazobactum/Tiecoplanin or Vancomycin/Cloxacilin/Ceftazidime. In non-responders, amphotaracin was added until recovery. Out of 52 patients, 5 did not develop any fever; in the remaining 47 patients there were 57 episodes of febrile neutropenia. The mean days of febrile episodes were 4.71 (range 3-8). Fever of unknown origin (FUO) occurred in 31 (54.3%) episodes. Microbiologically documented infection (MDI) occurred in 17 (29.8%) episodes of fever. Clinically documented infection (CDI) occurred in 9 (15.7%) episodes. Gram-negative organisms were isolated in 10 while gram-positive organisms in 7. Klebseilla, S. aureus were the most common isolates. Empirical therapy was effective in 12 of the 33 (36%) episodes. Out of 28, 26 (92%) responded to Imipenem/Amikacin as second line therapy while those who received any other second line combination, only 11 out of 22 (50%) showed response.

A number of studies have demonstrated induction of the unfolded protein response (UPR) in patients with severe congenital neutropenia (CN) harbouring mutations of ELANE, encoding neutrophil elastase. Why UPR is not activated in patients with cyclic neutropenia (CyN) carrying the same ELANE mutations is unclear. We evaluated the effects of ELANE mutants on UPR induction in myeloid cells from CN and CyN patients, and analysed whether additional CN-specific defects contribute to the differences in UPR induction between CN and CyN patients harbouring identical ELANE mutations. We investigated CN-specific p.C71R and p.V174_C181del (NP_001963.1) and CN/CyN-shared p.S126L (NP_001963.1) ELANE mutants. We found that transduction of haematopoietic cells with p.C71R, but not with p.V174_C181del or p.S126L ELANE mutants induced expression of ATF6, and the ATF6 target genes PPP1R15A, DDIT3 and HSPA5. Recently, we found that levels of secretory leucocyte protease inhibitor (SLPI), a natural ELANE inhibitor, are diminished in myeloid cells from CN patients, but not CyN patients. Combined knockdown of SLPI by shRNA and transduction of ELANE p.S126L in myeloid cells led to elevated levels of ATF6, PPP1R15A and HSPA5 RNA, suggesting that normal levels of SLPI in CyN patients might protect them from the UPR induced by mutant ELANE. In summary, different ELANE mutants have different effects on UPR activation, and SLPI regulates the extent of ELANE-triggered UPR. © 2015 John Wiley & Sons Ltd.

The relationship between oesophageal radiation dose volume metrics and dysphagia in patients having chemoradiation (CRT) for non-small cell lung cancer (NSCLC) is well established. There is also some evidence that neutropenia is a factor contributing to the severity of oesophagitis. We retrospectively analysed acute radiation oesophagitis (ARO) rates and severity in patients with NSCLC who received concurrent chemotherapy and high dose radiation therapy (CRT). We investigated if there was an association between grade of ARO, neutropenia and radiation dose volume metrics. Patients with NSCLC having concurrent CRT who had RT dose and toxicity data available were eligible. Exclusion criteria included previous thoracic RT, treatment interruptions and non-standard dose regimens. RT dosimetrics included maximum and mean oesophageal dose, oesophagus dose volume and length data. Fifty four patients were eligible for analysis. 42 (78 %) patients received 60 Gy. Forty four (81 %) patients received carboplatin based chemotherapy. Forty eight (89 %) patients experienced ARO ≥ grade 1 (95 % CI: 78 % to 95 %).

Childhood chronic neutropenia with decreased numbers of chemotactic factor receptors as well as defective chemotaxis was first demonstrated in an 8-month-old girl. Chemotactic factor receptors on neutrophils were assayed using tritiated N-formyl-methionyl-leucyl-phenylalanine ( 3 H-FMLP). The patient's neutrophils had decreased numbers of the receptors: numbers of the receptors were 20,000 (less than 3 SD) as compared with those of control cells of 52,000 +/- 6000 (mean +/- SD) (n = 10). The neutropenia disappeared spontaneously by 28 months of age parallel with the improvement of chemotaxis and increase in numbers of chemotactic factor receptors. These results demonstrate a transient decrease of neutrophil chemotactic factor receptors as one of the pathophysiological bases of a transient defect of neutrophil chemotaxis in this disorder

Blood cultures (BCs) are essential in the evaluation of neutropenic fever. Modern BC systems have significantly reduced the time-to-positivity (TTP) of BC. This study explores the probability of bacteraemia when BCs have remained negative for different periods of time. All adult patients with neutropenia and bacteraemia were included (January 2012-February 2016). Predictive clinical factors for short (≤16 hours) and long (>24 hours) TTP were determined. The residual probability of bacteraemia was estimated for the scenario of negative BC 24 hours after collection. The cohort consisted of 154 patients, accounting for 190 episodes of bacteraemia. Median age of 61 years, 60.5% were male. In 123 (64.7%) episodes, BC yielded a single Gram-positive micro-organism and in 49 (25.8%) a Gram-negative micro-organism (median TTP 16.7, 14.5 hours respectively, P hours in 91.6% of episodes. Central line-associated bacteraemia was associated with long TTP. The probability of bacteraemia if BC had remained negative for 24 hours was 1%-3%. The expected TTP offers guidance in the management of patients with neutropenia and suspected bacteraemia. The knowledge of negative BC can support a change in working diagnosis, and impact clinical decisions as soon as 24 hours after BC collection. © 2017 John Wiley & Sons A/S.

Full Text Available Background. Chemotherapy-induced neutropenia (CIN can result in poor tolerance of chemotherapy, leading to dose reductions, delays in therapy schedules, morbidity and mortality. Actively identifying predisposing risk factors before treatment is of paramount importance. We hypothesised that chemotherapy is associated with a greater increase in CIN and its complications in HIV-infected patients than in those who are not infected. Objective. To establish the incidence of CIN in HIV-infected and uninfected patients undergoing chemotherapy. Methods. A retrospective chart review and analysis was conducted in the oncology departments at Inkosi Albert Luthuli Central Hospital and Addington Hospital, Durban, South Africa. The study population consisted of 65 previously untreated women of all ages with stage II - IV breast cancer and known HIV status treated with neoadjuvant chemotherapy from January 2012 to December 2015. Results. HIV-infected patients formed 32.3% of the group, and 95.2% of them were on antiretroviral therapy. The mean age (standard deviation (SD of the cohort was 48.5 (13.2 years (40.6 (9.6 years for the HIV-infected group v. 52.0 (13.1 years for the uninfected group; p<0.001. Ninety-five neutropenia episodes were observed (rate 0.85 per 1 year of follow-up time. Following multivariate adjustment, patients with HIV infection were almost two times more likely to develop CIN (hazard ratio (HR 1.76, 95% confidence interval (CI 1.06 - 2.92; p=0.029. A high baseline absolute neutrophil count (ANC (HR 0.80, 95% CI 0.68 - 0.95; p=0.005 remained significantly associated with protection against CIN. Conclusions. HIV-infected patients were younger than those who were not infected, and presented at a more locally advanced stage of disease. HIV infection was an independent predictor for CIN. HIV-infected patients had an almost two-fold increased risk of developing CIN and developed neutropenia at a much faster rate. A high baseline white cell

Characterisation of Neutropenia-Associated Neutrophil Elastase Mutations in a Murine Differentiation Model In Vitro and In Vivo.

Directory of Open Access Journals (Sweden)

Full Text Available Severe congenital neutropenia (SCN is characterised by a differentiation block in the bone marrow and low neutrophil numbers in the peripheral blood, which correlates with increased risk of bacterial infections. Several underlying gene defects have been identified in SCN patients. Mutations in the neutrophil elastase (ELANE gene are frequently found in SCN and cyclic neutropenia. Both mislocalization and misfolding of mutant neutrophil elastase protein resulting in ER stress and subsequent induction of the unfolded protein response (UPR have been proposed to be responsible for neutrophil survival and maturation defects. However, the detailed molecular mechanisms still remain unclear, in part due to the lack of appropriate in vitro and in vivo models. Here we used a system of neutrophil differentiation from immortalised progenitor lines by conditional expression of Hoxb8, permitting the generation of mature near-primary neutrophils in vitro and in vivo. NE-deficient Hoxb8 progenitors were reconstituted with murine and human forms of typical NE mutants representative of SCN and cyclic neutropenia, and differentiation of the cells was analysed in vitro and in vivo. ER stress induction by NE mutations could be recapitulated during neutrophil differentiation in all NE mutant-reconstituted Hoxb8 cells. Despite ER stress induction, no change in survival, maturation or function of differentiating cells expressing either murine or human NE mutants was observed. Further analysis of in vivo differentiation of Hoxb8 cells in a murine model of adoptive transfer did not reveal any defects in survival or differentiation in the mouse. Although the Hoxb8 system has been found to be useful for dissection of defects in neutrophil development, our findings indicate that the use of murine systems for analysis of NE-mutation-associated pathogenesis is complicated by differences between humans and mice in the physiology of granulopoiesis, which may go beyond possible

The effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on the recovery from neutropenia induced by fractionated whole-body irradiation was investigated in mice. Male 7-week old C3H/HeN mice received a total of ten exposures of 0.25 Gy/day from day 1 to 5 and from day 8 to 12. Peripheral neutropenia with a nadir on day 17 was caused by the fractionated irradiation. Daily subcutaneous injections of rhG-CSF at 0.25 and 2.5 [mu]g/body/day from day from day 1 to 21 promoted the recovery of neutrophils in a dose-dependent manner. The kinetics of morphologically identifiable bone marrow cells were studied to clarify the mechanism behind the promotive effect of this factor. A slight decrease in mitotic immature granulocytes, such as myeloblasts, promyelocytes and myelocytes on day 5, and a drastic decrease in metamyelocytes and marrow neutrophils on days 5, 9, and 17 were seen in the femur of irradiated mice. Treatment using rhG-CSF caused an increase in immature granulocytes of all differential stages in the femur. Microscopic findings of the femurs and spleens also reveals an increase in immature granulocytes in these organs in mice injected with rhG-CSF. These results indicate that rhG-CSF accelerates granulopoiesis in the femur and spleen, thereby promoting recovery from neutropenia induced by fractionated irradiation. (author).

The recommended dose of prophylactic pegylated recombinant human granulocyte-colony stimulating factor (PEG rhG-CSF) is 100 μg/kg once per cycle for patients receiving intense-dose chemotherapy. However, few data are available on the proper dose for patients receiving less-intense chemotherapy. The aim of this phase I study is to explore the proper dose and administration schedule of PEG rhG-CSF for patients receiving standard-dose chemotherapy. Eligible patients received 3-cycle chemotherapy every 3 weeks. No PEG rhG-CSF was given in the first cycle. Patients experienced grade 3 or 4 neutropenia would then enter the cycle 2 and 3. In cycle 2, patients received a single subcutaneous injection of prophylactic PEG rhG-CSF on d 3, and received half-dose subcutaneous injection in cycle 3 on d 3 and d 5, respectively. Escalating doses (30, 60, 100 and 200 μg/kg) of PEG rhG-CSF were investigated. A total of 26 patients were enrolled and received chemotherapy, in which 24 and 18 patients entered cycle 2 and cycle 3 treatment, respectively. In cycle 2, the incidence of grade 3 or 4 neutropenia for patients receiving single-dose PEG rhG-CSF of 30, 60, 100 and 200 μg/kg was 66.67%, 33.33%, 22.22% and 0, respectively, with a median duration less than 1 (0-2) d. No grade 3 or higher neutropenia was noted in cycle 3 in all dose cohorts. The pharmacokinetic and pharmacodynamic profiles of PEG rhG-CSF used in cancer patients were similar to those reported, as well as the safety. Double half dose administration model showed better efficacy result than a single dose model in terms of grade 3 neutropenia and above. The single dose of 60 μg/kg, 100 μg/kg and double half dose of 30 μg/kg were recommended to the phase II study, hoping to find a preferable method for neutropenia treatment.

Full Text Available Abstract Background For its low cost and ease of handling, the mouse remains the preferred experimental animal for preclinical tests. To avoid the interaction of the animal immune system, in vivo antibiotic pharmacodynamic studies often employ cyclophosphamide (CPM to induce neutropenia. Although high doses (350–450 mg/kg are still used and their effects on mouse leukocytes have been described, a lower dose (250 mg/kg is widely preferred today, but the characteristics and applicability of this approach in outbred mice have not been determined. Methods Fifteen female ICR mice were injected intraperitoneally with 150 and 100 mg/kg of CPM on days 1 and 4, respectively. Blood samples (~160 μL were drawn from the retro-orbital sinus of each mouse on days 1, 4, 5, 6, 7 and 11. Leukocytes were counted manually and the number of granulocytes was based on microscopic examination of Wright-stained smears. The impact of neutropenia induced by this method was then determined with a variety of pathogens in three different murine models of human infections: pneumonia (Klebsiella pneumoniae, Streptococcus pneumoniae, Staphylococcus aureus, meningoencephalitis (S. pneumoniae, and the thigh model (S. aureus, Escherichia coli, Bacteroides fragilis. Results The basal count of leukocytes was within the normal range for outbred mice. On day 4, there was an 84% reduction in total white blood cells, and by day 5 the leukopenia reached its nadir (370 ± 84 cells/mm3. Profound neutropenia (≤10 neutrophils/mm3 was demonstrated at day 4 and persisted through days 5 and 6. Lymphocytes and monocytes had a 92% and 96% decline between days 1 and 5, respectively. Leukocytes recovered completely by day 11. Mice immunosupressed under this protocol displayed clinical and microbiological patterns of progressive and lethal infectious diseases after inoculation in different organs with diverse human pathogens. Conclusion A CPM total dose of 250 mg/kg is sufficient to induce

To validate a prognostic score predicting major complications in patients with solid tumors and seemingly stable episodes of febrile neutropenia (FN). The definition of clinical stability implies the absence of organ dysfunction, abnormalities in vital signs, and major infections. We developed the Clinical Index of Stable Febrile Neutropenia (CISNE), with six explanatory variables associated with serious complications: Eastern Cooperative Oncology Group performance status ≥ 2 (2 points), chronic obstructive pulmonary disease (1 point), chronic cardiovascular disease (1 point), mucositis of grade ≥ 2 (National Cancer Institute Common Toxicity Criteria; 1 point), monocytes < 200 per μL (1 point), and stress-induced hyperglycemia (2 points). We integrated these factors into a score ranging from 0 to 8, which classifies patients into three prognostic classes: low (0 points), intermediate (1 to 2 points), and high risk (≥ 3 points). We present a multicenter validation of CISNE. We prospectively recruited 1,133 patients with seemingly stable FN from 25 hospitals. Complication rates in the training and validation subsets, respectively, were 1.1% and 1.1% in low-, 6.1% and 6.2% in intermediate-, and 32.5% and 36% in high-risk patients; mortality rates within each class were 0% in low-, 1.6% and 0% in intermediate-, and 4.3% and 3.1% in high-risk patients. Areas under the receiver operating characteristic curves in the validation subset were 0.652 (95% CI, 0.598 to 0.703) for Talcott, 0.721 (95% CI, 0.669 to 0.768) for Multinational Association for Supportive Care in Cancer (MASCC), and 0.868 (95% CI, 0.827 to 0.903) for CISNE (P = .002 for comparison between CISNE and MASCC). CISNE is a valid model for accurately classifying patients with cancer with seemingly stable FN episodes. © 2015 by American Society of Clinical Oncology.

In two major clinical trials, voriconazole and caspofungin were recommended as alternatives to liposomal amphotericin B for empirical use in febrile neutropenia. This study investigated the health economic impact of using voriconazole vs. caspofungin in patients with febrile neutropenia. A decision analytic model was developed to measure downstream consequences of empirical antifungal therapy. Clinical outcomes measured were success, breakthrough infection, persistent base-line infection, persistent fever, premature discontinuation and death. Treatment transition probabilities and patterns were directly derived from data in two relevant randomised controlled trials. Resource use was estimated using an expert clinical panel. Cost inputs were obtained from latest Australian sources. The analysis adopted the perspective of the Australian hospital system. The use of caspofungin led to a lower expected mean cost per patient than voriconazole (AU$40,558 vs. AU$41,356), with a net cost saving of AU$798 (1.9%) per patient. Results were most sensitive to the duration of therapy and the alternative therapy used post-discontinuation. In uncertainty analysis, the cost associated with caspofungin is less than that with voriconazole in 65.5% of cases. This is the first economic evaluation of voriconazole vs. caspofungin for empirical therapy. Caspofungin appears to have a higher probability of having cost-savings than voriconazole for empirical therapy. The difference between the two medications does not seem to be statistically significant however. © 2011 Blackwell Verlag GmbH.

Full Text Available Pressure ulcers remain a major health issue for critical patients. The purpose of this descriptive and exploratory study was to analyze the risk factors for the development of pressure ulcers in patients hospitalized at an intensive care unit of a university hospital. Patients were assessed through the Braden scale to determine the risk for the development of pressure ulcers and to identify individual risks, and the Glasgow scale was used to assess their consciousness. It was found that the risks associated with pressure ulcer development were: low scores on the Braden Scale on the first hospitalization day and low scores on the Glasgow scale. The results showed that these tools can help nurses to identify patients at risk, with a view to nursing care planning.Las ulceras de presión todavía representan un gran problema de salud en pacientes críticos.

Since its publication more than 15 years ago, the MASCC score has been internationally validated any number of times and recommended by most clinical practice guidelines for the management of febrile neutropenia (FN) around the world. We have used an empirical data-supported simulated scenario to demonstrate that, despite everything, the MASCC score is impractical as a basis for decision-making. A detailed analysis of reasons supporting the clinical irrelevance of this model is performed. First, seven of its eight variables are "innocent bystanders" that contribute little to selecting low-risk candidates for ambulatory management. Secondly, the training series was hardly representative of outpatients with solid tumors and low-risk FN. Finally, the simultaneous inclusion of key variables both in the model and in the outcome explains its successful validation in various series of patients. Alternative methods of prognostic classification, such as the Clinical Index of Stable Febrile Neutropenia, have been specifically validated for patients with solid tumors and should replace the MASCC model in situations of clinical uncertainty.

Hakim, R M; Lowrie, E G

1982-01-01

The fall in white blood cells (WBC) and arterial oxygen pressure that occurs during hemodialysis was investigated as a function of different dialysis membranes and different sterilization methods. 8 chronic hemodialysis patients were studied and each was dialyzed with three different membranes: cellulosic hollow fiber, polyacrylonitrile flat sheet and polymethylmethacrylate hollow fiber. Each dialyzer was studied with a dry sterilization method and after formalin treatment. Arterialized blood gas, bicarbonate and WBC were drawn at various intervals throughout dialysis. The effect of the sterilization method was minimal. Cellulosic membranes were shown to cause significantly more neutropenia (p less than 0.001) and hypoxemia (p less than 0.01) than the other two membranes. No significant differences was seen in pH, PCO2 and bicarbonate. The results indicate differences in biocompatibility between different membranes. Clinical implications are discussed.

Fluoroquinolones reduce occurrence of fever in adult cancer patients who develop neutropenia, but there has been no randomized controlled trial in children, and there are only a few studies considering resistance in intestinal floral after ciprofloxacin has been used. Children younger than 18 years with acute lymphoblastic leukemia or lymphoma scheduled to undergo chemotherapy were randomized to receive oral ciprofloxacin 20mg/kg/day or placebo from the beginning of their chemotherapy. Rectal swab cultures were taken before and at 1 and/or 2 weeks after the intervention. Of the total of 95 patients, 45 and 50 patients received ciprofloxacin and placebo, respectively. Of the 71 patients who developed neutropenia, the proportion of children who developed fever was significantly lower in the ciprofloxacin group than in the placebo group (17/34 [50.0%] versus 27/37 [73.0%]; absolute difference in risk, -23.0%; 95% confidence interval: -45.0% to -0.9%; P = 0.046). Ciprofloxacin significantly reduced the occurrence of febrile episodes in patients with acute lymphoblastic leukemia in the induction phase of chemotherapy, but not in patients with lymphoma or in the consolidation phase of chemotherapy. Adverse effects were not different between the groups. After intervention, the percentages of Escherichia coli and Klebsiella pneumoniae susceptible to ciprofloxacin were significantly lower in the ciprofloxacin group. Ciprofloxacin can prevent fever in neutropenic patients with acute lymphoblastic leukemia during the induction phase of chemotherapy with good tolerance and no serious side effects. Due to the selective pressure of intestinal flora resistance to ciprofloxacin, the long-term effectiveness needs further investigation.

Skin, blood, and urine cultures were taken. Oral quinolone prophylaxis was started in patients with neutropenia without fever. Empiric starting therapy consisted of amikacin in combination with cefepime.Results: A total of 3624 bacteria were isolated. The most common pathogens were coagulase-negative Staphylococci (46%, followed by Escherichia coli (25%, Enterobacteriaceae (15.6%, Staphylococcus aureus (7.2%, and Pseudomonas aeruginosa (3.8%. The balance between Gram-positive and Gram-negative bacteria remained stable, with a majority of Gram-positive bacteria. A shift from oxacillin-sensitive to oxacillin-resistant coagulase-negative Staphylococci was observed. Regarding susceptibility patterns, no vancomycin resistance was detected in coagulase-negative Staphylococci or in S. aureus. The E. coli susceptibility rates remained stable. However, 66% of bloodstream infections were ciprofloxacin-resistant.

Severe neutropenia (SN) is a rare disorder in childhood. This study aimed to document the approach to diagnosis and treatment of children with SN in a single university-based children's hospital, determine the types of SN seen in a 4-year period, and determine outcomes of the subtypes of SN. Forty-five children with SN were identified between 2000 and 2004. Two patients had autoimmune, 3 congenital, 3 familial, 6 cyclic, and 31 idiopathic SN. The median age of the patients with idiopathic SN was 15 months (3 mo to 17 y). Thirteen patients with idiopathic SN received filgrastim and 18 were observed. The history of severe infection and hospitalization at presentation was significantly more common among the patients who received filgrastim than those observed, but was not different between the 2 groups during the follow-up period. SN resolved in 16 patients and persisted in 14 patients. One patient with idiopathic SN did not respond to filgrastim and died of sepsis while she was still neutropenic. In summary, the majority of patients with SN had idiopathic SN, the infection risk was variable, treatment was based on clinical judgment rather than absolute neutrophil count, and approximately half of the patients had complete recovery.

Full Text Available Abstract Background Severe congenital neutropenia type 4 (SCN4 is an autosomal recessive disorder caused by mutations in the third subunit of the enzyme glucose-6-phosphatase (G6PC3. Its core features are congenital neutropenia and a prominent venous skin pattern, and affected individuals have variable birth defects. Oculocutaneous albinism type 4 (OCA4 is caused by autosomal recessive mutations in SLC45A2. Methods We report a sister and brother from Newfoundland, Canada with complex phenotypes. The sister was previously reported by Cullinane et al., 2011. We performed homozygosity mapping, next generation sequencing and conventional Sanger sequencing to identify mutations that cause the phenotype in this family. We have also summarized clinical data from 49 previously reported SCN4 cases with overlapping phenotypes and interpret the medical histories of these siblings in the context of the literature. Results The siblings’ phenotype is due in part to a homozygous mutation in G6PC3, [c.829C > T, p.Gln277X]. Their ages are 38 and 37 years respectively and they are the oldest SCN4 patients published to date. Both presented with congenital neutropenia and later developed Crohn disease. We suggest that the latter is a previously unrecognized SCN4 manifestation and that not all affected individuals have an intellectual disability. The sister also has a homozygous mutation in SLC45A2, which explains her severe oculocutaneous hypopigmentation. Her brother carried one SLC45A2 mutation and was diagnosed with “partial OCA” in childhood. Conclusions This family highlights that apparently novel syndromes can in fact be caused by two known autosomal recessive disorders.

Is the addition of aminoglycosides to beta-lactams in cancer patients with febrile neutropenia needed?

It is still controversial if the combined use of beta-lactam antibiotics and aminoglycosides has advantages over broad-spectrum beta-lactam monotherapy for the empirical treatment of cancer patients with febrile neutropenia. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including 14 pertinent randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded the combination of beta-lactam antibiotics and aminoglycosides probably does not lead to a reduced mortality in febrile neutropenic cancer patients and it might increase nephrotoxicity.

Chronic idiopathic neutropenia (CIN) is an acquired disorder of granulopoiesis characterized by female predominance and mostly uncomplicated course. Crucial to CIN pathophysiology is the presence of activated T lymphocytes with myelosuppressive properties in both peripheral blood (PB) and bone marrow (BM). We systematically profiled the T cell receptor beta chain (TRB) gene repertoire in CD8 + cells of 34 CIN patients through subcloning/Sanger sequencing analysis of TRBV-TRBD-TRBJ gene rearrangements. Remarkable repertoire skewing and oligoclonality were observed, along with shared clonotypes between different patients, alluding to antigen selection. Cross-comparison of our sequence dataset with public TRB sequence databases revealed that CIN may rarely share common immunogenetic features with other entities, however, the CIN TRB repertoire is largely disease-biased. Overall, these findings suggest that CIN may be driven by long-term exposure to a restricted set of specific CIN-associated antigens.

Full Text Available Objective: The aim of this study is to investigate if neutrophil CD64 expression in febrile neutropenia patients could be used as an early indicator of bacteremia. Materials and Methods: All consecutive patients older than 18 years of age who had developed febrile neutropenia episodes due to hematological malignancies were included in the study. Those patients who had significant growth in their blood cultures constituted the case group, while those who had febrile neutropenia without any growth in their cultures and who did not have any documented infections formed the control group. Blood culture bottles were incubated in the Bact ALERT 3D system (bioMerieux, France, identification and susceptibility testing were performed using an automated broth microdilution method (VITEK 2, bioMerieux, and CD64 expression analysis was performed by the flow cytometry method. C-reactive protein (CRP was measured by turbidimetric methods (Biosystems, Spain and erythrocyte sedimentation rate (ESR was measured by the Wintrobe method. Results: In total, we prospectively evaluated 31 febrile episodes. The case group consisted of 17 patients while the control group included 14 patients. CD64 was found on neutrophils of the case group patients with a mean count of 8006 molecules/cell and of control group with a mean count of 2786 molecules/cell. CD64 levels of the case group were significantly higher than those of the control group (p=0.005. In the differentiation of the case group from the control group, a 2500 cut-off value for CD64 had significant [AUC=0.792 (0.619-0.965] predictive value (p=0.001. In the prediction of patients with a 2500 cut-off value for CD64, sensitivity was 94.1%, positive predictive value was 76.2%, specificity was 64.3%, and negative predictive value was 90.0%. CRP levels and ESR values did not differ significantly between the groups (p=0.005. Conclusion: Neutrophil CD64 expression could be a good predictor as an immune parameter with

Clericuzio-type poikiloderma with neutropenia is a well-defined nosological entity, but despite a remarkable number of clinical reports, no long term follow-up data has been presented to date regarding patients with this rare condition. Here we describe the results of clinical follow-up of three siblings, one male (Patient 1) and two females (Patients 2 and 3), subsequent to their first clinical and then molecular diagnosis of Clericuzio-type poikiloderma with neutropenia syndrome due to mutation of USB1gene. Patient 1 always expressed the most severe phenotype, while patients 2 and 3 showed an intermediate and mild phenotype, respectively, as observed since their first clinical evaluation. None of the patients developed skin cancer and/or myelodysplastic disorders considering the peripheral haematological findings. Lens opacity, never reported before, was found in two of the three patients. The long term follow-up observations confirm the stability over time of the pronounced intra-familial heterogeneity of clinical manifestations observed prior to and upon molecular diagnosis. We conclude that prolonged follow-up is an adjunct tool to monitor intra-familial variability of PN clinical spectrum which may favour surveillance of more serious complications of the disease among siblings, when a patient-specific clinical expressivity is present.

Full Text Available Objective and Importance. Cyclic neutropenia (CyN is a rare autosomal dominant inherited disorder due to the mutation ELANE primarily affecting bone marrow stem cells and is characterized by recurrent neutropenia every 2 to 4 weeks. Symptoms vary from benign to severe, including death. Postulations on the cause of wide spectrum in symptom presentation include the possibility of other genetic mutations, such as MEFV. Recommended treatment for CyN is G-CSF to keep ANC higher to minimize risk of infection. Case. A 25-year-old male diagnosed with CyN, on G-CSF but worsening quality of life. Pretransplant investigations revealed ELANE mutation positive severe CyN along with familial Mediterranean fever (MEFV mutation. Intervention. Bone marrow transplantation as treatment for dual mutation (ELANE and MEFV mutation positive severe CyN. Conclusion. BMT may be considered as an alternative treatment for severe CyN in patients who are refractory to G-CSF. It is postulated that in our patient the combined mutations (CyN and MEFV may have contributed to the severity of this individual’s symptoms. We suggest CyN patients who present with severe symptoms have evaluation with ELANE mutation testing, Periodic Fever Syndromes Panel, and routine marrow assessment with FISH, conventional cytogenetics, and morphological evaluation for MDS/AML.

Febrile neutropenia (FNP) is a frequent complication of cancer care and evaluation often fails to identify a cause. [ 18 F]FDG PET/CT has the potential to identify inflammatory and infectious foci, but its potential role as an investigation for persistent FNP has not previously been explored. The aim of this study was to prospectively evaluate the clinical utility of FDG PET/CT in patients with cancer and severe neutropenia and five or more days of persistent fever despite antibiotic therapy. Adult patients with a diagnosis of an underlying malignancy and persistent FNP (temperature ≥38 C and neutrophil count <500 cells/μl for 5 days) underwent FDG PET/CT as an adjunct to conventional evaluation and management. The study group comprised 20 patients with FNP who fulfilled the eligibility criteria and underwent FDG PET/CT in addition to conventional evaluation. The median neutrophil count on the day of the FDG PET/CT scan was 30 cells/μl (range 0-730 cells/μl). Conventional evaluation identified 14 distinct sites of infection, 13 (93 %) of which were also identified by FDG PET/CT, including all deep tissue infections. FDG PET/CT identified 9 additional likely infection sites, 8 of which were subsequently confirmed as ''true positives'' by further investigations. FDG PET/CT was deemed to be of 'high' clinical impact in 15 of the 20 patients (75 %). This study supports the utility of FDG PET/CT scanning in severely neutropenic patients with five or more days of fever. Further evaluation of the contribution of FDG PET/CT in the management of FNP across a range of underlying malignancies is required. (orig.)

Full Text Available Cyclic Neutropenia (CN is characterized by recurrent infections, fever, oral ulcerations, and severe periodontitis as result of the reduced host defences. The previous studies have established the effectiveness of recombinant granulocyte colony-stimulating factor (GCSF to increase the number and the function of neutrophils in the peripheral blood in this disease. In a 20-year-old Caucasian female with a diagnosis of cyclic neutropenia, oral clinical examination revealed multiple painful ulcerations of the oral mucosa, poor oral hygiene conditions, marginal gingivitis, and moderate periodontitis. The patient received a treatment with G-CSF (Pegfilgrastim, 6 mg/month in order to improve her immunological status. Once a month nonsurgical periodontal treatment was carefully performed when absolute neutrophil count (ANC was ≥500/L. The treatment with G-CSF resulted in a rapid increase of circulating neutrophils that, despite its short duration, leaded to a reduction in infection related events and the resolution of the multiple oral ulcerations. The disappearance of oral pain allowed an efficacy nonsurgical treatment and a normal tooth brushing that determined a reduction of probing depth (PD≤4 mm and an improvement of the oral hygiene conditions recorded at 6-month follow-up.

Between 30 and 50% of febrile neutropenic episodes are accounted for by infection. C-reactive protein (CRP) is a nonspecific parameter for infection and inflammation but might be employed as a trigger for diagnosis. The aim of the study was to evaluate whether {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT can be used to detect inflammatory foci in neutropenic patients with elevated CRP and whether it helps to direct treatment. Twenty-eight consecutive patients with neutropenia as a result of intensive chemotherapy for haematological malignancies or myeloablative therapy for haematopoietic stem cell transplantation were prospectively included. {sup 18}F-FDG PET/CT was added to the regular diagnostic workup once the CRP level rose above 50 mg/l. Pathological FDG uptake was found in 26 of 28 cases despite peripheral neutrophil counts less than 0.1 x 10{sup -9}/l in 26 patients: in the digestive tract in 18 cases, around the tract of the central venous catheter (CVC) in 9 and in the lungs in 7 cases. FDG uptake in the CVC tract was associated with coagulase-negative staphylococcal bacteraemia (p < 0.001) and deep venous thrombosis (p = 0.002). The number of patients having Streptococcus mitis bacteraemia appeared to be higher in patients with grade 3 oesophageal FDG uptake (p = 0.08). Pulmonary FDG uptake was associated with the presence of invasive fungal disease (p = 0.04). {sup 18}F-FDG PET/CT scanning during chemotherapy-induced febrile neutropenia and increased CRP is able to detect localized foci of infection and inflammation despite the absence of circulating neutrophils. Besides its potential role in detecting CVC-related infection during febrile neutropenia, the high negative predictive value of {sup 18}F-FDG PET/CT is important for avoiding unnecessary diagnostic tests and therapy.

Severe congenital neutropenia (SCN) is characterized by low numbers of peripheral neutrophil granulocytes and a predisposition to life-threatening bacterial infections. We describe a novel genetic SCN type in 2 unrelated families associated with recessively inherited loss-of-function mutations in CSF3R, encoding the granulocyte colony-stimulating factor (G-CSF) receptor. Family A, with 3 affected children, carried a homozygous missense mutation (NM_000760.3:c.922C>T, NP_000751.1:p.Arg308Cys), which resulted in perturbed N-glycosylation and aberrant localization to the cell surface. Family B, with 1 affected infant, carried compound heterozygous deletions provoking frameshifts and premature stop codons (NM_000760.3:c.948_963del, NP_000751.1:p.Gly316fsTer322 and NM_000760.3:c.1245del, NP_000751.1:p.Gly415fsTer432). Despite peripheral SCN, all patients had morphologic evidence of full myeloid cell maturation in bone marrow. None of the patients responded to treatment with recombinant human G-CSF. Our study highlights the genetic and morphologic SCN variability and provides evidence both for functional importance and redundancy of G-CSF receptor-mediated signaling in human granulopoiesis. © 2014 by The American Society of Hematology.

We used differential time to positivity between central and peripheral blood cultures to evaluate the positive predictive value (PPV) of the National Healthcare Safety Network central line-associated bloodstream infection (CLABSI) surveillance definition among hematology patients with febrile neutropenia. The PPV was 27.7%, which suggests that, when the definition is applied to this population, CLABSI rates will be substantially overestimated.

Chemotherapy-induced neutropenia often increases the likelihood of life-threatening infections. In this study, a nanoparticle (NP) system composed of chitosan and poly(γ-glutamic acid) conjugated with diethylene triamine pentaacetic acid (γPGA-DTPA) was prepared for oral delivery of granulocyte colony-stimulating factor (G-CSF), a hematopoietic growth factor. The therapeutic potential of this NP system for daily administration of G-CSF to treat neutropenia associated with chemotherapy was evaluated in a rat model. In vitro results indicate that the procedures of NP loading and release preserved the structural integrity and bioactivity of the G-CSF molecules adequately. Those results further demonstrated the enzymatic inhibition activity of γPGA-DTPA towards G-CSF against intestinal proteases. Additionally, the in vivo biodistribution study clearly identified accumulations of G-CSF in the heart, liver, bone marrow, and urinary bladder, an indication of systemic absorption of G-CSF; its relative bioavailability was approximately 13.6%. Moreover, significant glucose uptake was observed in bone marrow during G-CSF treatment, suggesting increased bone marrow metabolism and neutrophil production. Consequently, neutrophil count in the blood increased in a sustained manner; this fact may help a patient's immune system recover from the side effects of chemotherapy. Copyright © 2014 Elsevier Ltd.

Although the molecular pathways that cause acute myeloid leukemia (AML) are increasingly well understood, the pathogenesis of peripheral blood cytopenia, a major cause of AML mortality, remains obscure. A prevailing assumption states that AML spatially displaces nonleukemic hematopoiesis from the bone marrow. However, examining an initial cohort of 223 AML patients, we found no correlation between bone marrow blast content and cytopenia, questioning the displacement theory. Measuring serum concentration of thrombopoietin (TPO), a key regulator of hematopoietic stem cells and megakaryocytes, revealed loss of physiologic negative correlation with platelet count in AML cases with blasts expressing MPL, the thrombopoietin (scavenging) receptor. Mechanistic studies demonstrated that MPL hi blasts could indeed clear TPO, likely therefore leading to insufficient cytokine levels for nonleukemic hematopoiesis. Microarray analysis in an independent multicenter study cohort of 437 AML cases validated MPL expression as a central predictor of thrombocytopenia and neutropenia in AML. Moreover, t(8;21) AML cases demonstrated the highest average MPL expression and lowest average platelet and absolute neutrophil counts among subgroups. Our work thus explains the pathophysiology of peripheral blood cytopenia in a relevant number of AML cases. © 2016 by The American Society of Hematology.

El Hospital General de Asturias, en 1963, y la Clínica Puerta de Hierro de Madrid, en 1964, iniciaron la formación de médicos internos y residentes (MIR, pese a que contravenía lo estipulado en la Ley de especialidades de 1955 y a que entraba en conflicto con el sistema de especialización a través de las escuelas universitarias, entonces vigente. El nuevo sistema recibió un fuerte impulso coincidiendo con la expansión de las residencias de la Seguridad Social, y los principales centros hospitalarios lo fueron implantando progresivamente. En 1968 se constituyó el denominado “seminario de hospitales con programas de posgraduados”, que elaboró en 1970 el primer manual de acreditación de hospitales. Su influjo sobre el ministerio fue muy grande, y a partir de 1971 tienen lugar las primeras convocatorias de ámbito nacional, aunque por concurso de méritos y con entrevista local de los solicitantes. Recién creado el Ministerio de Sanidad y Seguridad Social, se publica el Real Decreto (RD 2015/1978, primera norma que reconoce que las enseñanzas de especialización podrán cursarse por el sistema de residencia, que se convertirá en obligatorio para las especialidades que requieran formación hospitalaria a partir de 1984. La reforma del sistema de FSE viene de la mano de la Ley 44/2003, de ordenación de las profesiones sanitarias, y sus disposiciones de desarrollo: el RD 1146/2006, que regula los derechos y deberes del residente; el RD 183/2008, que clasifica las especialidades y regula importantes aspectos del sistema de FSE; los decretos autonómicos de ordenación de la FSE (solo cinco hasta ahora, y, finalmente, el RD 639/2014, que regula la troncalidad, la reespecialización, las áreas de capacitación específica, las pruebas de acceso y otros aspectos. Sin embargo, toda esta extensa normativa reguladora, muy formalizada y que pretende la excelencia del sistema, contrasta con los importantes incumplimientos existentes y los numerosos desarrollos

Empirical antibiotics at the onset of febrile neutropenia are one of several strategies for management of bacterial infections in patients undergoing Hematopoietic Stem Cell Transplant (HSCT) (empiric strategy). Our HSCT program aims to perform HSCT in an outpatient setting, where an empiric antibiotic strategy was employed. HSCT recipients began receiving intravenous antibiotics at the onset of neutropenia in the absence of fever as part of our institutional policy from 01 Jan 2009; intravenous Prophylactic strategy. A prospective study was conducted to compare two consecutive cohorts [Year 2008 (Empiric strategy) vs. Year 2009 (Prophylactic strategy)] of patients receiving HSCT. There were 238 HSCTs performed between 01 Jan 2008 and 31 Dec 2009 with 127 and 111 in the earlier and later cohorts respectively. Infection-related mortality pre- engraftment was similar with a prophylactic compared to an empiric strategy (3.6% vs. 7.1%; p = 0.24), but reduced among recipients of autologous HSCT (0% vs. 6.8%; p = 0.03). Microbiologically documented, blood stream infections and clinically documented infections pre-engraftment were reduced in those receiving a prophylactic compared to an empiric strategy, (11.7% vs. 28.3%; p = 0.001), (9.9% vs. 24.4%; p = 0.003) and (18.2% vs. 33.9% p = 0.007) respectively. The prophylactic use of intravenous once-daily ceftriaxone in patients receiving outpatient based HSCT is safe and may be particularly effective in patients receiving autologous HSCT. Further studies are warranted to study the impact of this Prophylactic strategy in an outpatient based HSCT program. PMID:23029441

Totally implantable venous access port systems are widely used in oncology, with frequent complications that sometimes necessitate device removal. The aim of this study is to investigate the impact of the time interval between port placement and initiation of chemotherapy and the neutropenia-inducing potential of the chemotherapy administered upon complication-related port removal. Between January 2010 and December 2013, 4045 consecutive patients were included in this observational, single-center prospective study. The chemotherapy regimens were classified as having a low (20%) risk for inducing neutropenia. The overall removal rate due to complications was 7.2%. Among them, port-related infection (2.5%) and port expulsion (1%) were the most frequent. The interval between port insertion and its first use was shown to be a predictive factor for complication-related removal rates. A cut-off of 6 days was statistically significant (p = 0.008), as the removal rate for complications was 9.4% when this interval was 0-5 days and 5.7% when it was ≥6 days. Another factor associated with port complication rate was the neutropenia-inducing potential of the chemotherapy regimens used, with removal for complications involved in 5.5% of low-risk regimens versus 9.4% for the intermediate- and high-risk regimens (p = 0.003). An interval of 6 days between placement and first use of the port reduces the removal rate from complications. The intermediate- and high-risk for neutropenia chemotherapy regimens are related to higher port removal rates from complications than low-risk regimens.

Full Text Available Abstract Background Patients with chemotherapy-related neutropenia and fever are usually hospitalized and treated on empirical intravenous broad-spectrum antibiotic regimens. Early diagnosis of sepsis in children with febrile neutropenia remains difficult due to non-specific clinical and laboratory signs of infection. We aimed to analyze whether IL-6 and IL-8 could define a group of patients at low risk of septicemia. Methods A prospective study was performed to assess the potential value of IL-6, IL-8 and C-reactive protein serum levels to predict severe bacterial infection or bacteremia in febrile neutropenic children with cancer during chemotherapy. Statistical test used: Friedman test, Wilcoxon-Test, Kruskal-Wallis H test, Mann-Whitney U-Test and Receiver Operating Characteristics. Results The analysis of cytokine levels measured at the onset of fever indicated that IL-6 and IL-8 are useful to define a possible group of patients with low risk of sepsis. In predicting bacteremia or severe bacterial infection, IL-6 was the best predictor with the optimum IL-6 cut-off level of 42 pg/ml showing a high sensitivity (90% and specificity (85%. Conclusion These findings may have clinical implications for risk-based antimicrobial treatment strategies.

The purpose of this study was to compare the periodontal status of Yemenite Jews with and without benign familial neutropenia (BFN). Thirty-four volunteers were examined at baseline and after 3 years. Plaque index (PlI), bleeding index (BI) probing depth (PD), and attachment levels (AL) were recorded. Differential blood counts were done on at least three occasions during the study. Volunteers with at least one count of less than 2000 neutrophils were considered neutropenic. The majority of patients received oral hygiene instructions and scaling at the initial visit. During the study there was a significant drop in PlI (P less than 0.01) and BI (P less than 0.05). At baseline the BFN and non-BFN volunteers had similar PlI, but the BI was significantly greater in the BFN group. At follow-up, there was a significantly greater number of teeth with pockets greater than or equal to 6 mm in the BFN group (P less than 0.05). These results indicate that volunteers with BFN, a phenomenon that has not previously been associated with any pathology, are more susceptible to gingival inflammation and attachment loss than unaffected volunteers and that they respond more favorably to an improvement in oral hygiene.

Monotherapy is recommended as the first choice for initial empirical therapy of febrile neutropenia, but local epidemiological and antibiotic susceptibility data are now considered pivotal to design a correct management strategy. To evaluate the proportion of Gram-negative rods isolated in bloodstream infections in children with cancer resistant to antibiotics recommended for this indication. The in vitro susceptibility to ceftazidime, piperacillin-tazobactam, meropenem and amikacin of Gram-negatives isolated in bacteremic episodes in children with cancer followed at the Istituto "Giannina Gaslini", Genoa, Italy in the period of 2001-2013 was retrospectively analyzed using the definitions recommended by EUCAST in 2014. Data were analyzed for any single drug and to the combination of amikacin with each β-lactam. The combination was considered effective in absence of concomitant resistance to both drugs, and not evaluated by means of in vitro analysis of antibiotic combinations (e.g., checkerboard). A total of 263 strains were evaluated: 27% were resistant to piperacillin-tazobactam, 23% to ceftazidime, 12% to meropenem and 13% to amikacin. Concomitant resistance to β-lactam and amikacin was detected in 6% of strains for piperacillin-tazobactam, 5% for ceftazidime and 5% for meropenem. During the study period there was a nonsignificant increase in the proportions of strains resistant to β-lactams indicated for monotherapy, and also increase in the resistance to combined therapies. in an era of increasing resistance to antibiotics guideline-recommended monotherapy could be not appropriate for initial empirical therapy of febrile neutropenia. Strict local survey on etiology and antibiotic susceptibility is mandatory for a correct management of this complication in cancer patients.

Full Text Available Current international guidelines for the management of immuno-compromised patients with febrile neutropenia recommend a systemic antimicrobial therapy if fever hasn’t receded after three days of antibiotic treatment. Amphotericin B remains the gold standard because of its broad spectrum fungicidal action and minimal resistance development risk. Nonetheless, therapeutic use of the standard formulation, Amphotericin B deoxycholate, is limited by its toxicity, especially on the kidneys. To counteract this, amphotericin B has been encapsulated in liposomes, a process which reduces its toxicity and allows higher doses to be given. Three lipid formulations have been developed and are now available in most countries: amB colloidal dispersion (ABCD, amB lipid complex (ABLC, and liposomal amB (L-AmB. These lipid formulations differ in pharmacodynamics and pharmacokinetics, and can’t therefore be considered interchangeable. Besides, they are more expensive than Amphotericin B deoxycholate. Aim of the study is to perform a cost/effectiveness analysis (CEA comparing L-AmB (3mg/kg/die or 5mg/kg/ die and ABLC (5mg/kg/die as first-line antimicrobial empirical treatments in immuno-compromised patients with febrile neutropenia resistant to broad spectrum antibiotics. Secondly, we present a cost-minimization analysis (CMA of the considered alternatives, assuming the same efficacy for all treatments. At the end we value the principal cost items from the point of view of the Italian Health Service, with a particular focus on the economic burden caused by adverse reactions.

This report describes an international prevalidation study conducted to optimise the Standard Operating Procedure (SOP) for detecting myelosuppressive agents by CFU-GM assay and to study a model for predicting (by means of this in vitro hematopoietic assay) the acute xenobiotic exposure levels that cause maximum tolerated decreases in absolute neutrophil counts (ANC). In the first phase of the study (Protocol Refinement), two SOPs were assessed, by using two cell culture media (Test A, containing GM-CSF; and Test B, containing G-CSF, GM-CSF, IL-3, IL-6 and SCF), and the two tests were applied to cells from both human (bone marrow and umbilical cord blood) and mouse (bone marrow) CFU-GM. In the second phase (Protocol Transfer), the SOPs were transferred to four laboratories to verify the linearity of the assay response and its interlaboratory reproducibility. After a further phase (Protocol Performance), dedicated to a training set of six anticancer drugs (adriamycin, flavopindol, morpholino-doxorubicin, pyrazoloacridine, taxol and topotecan), a model for predicting neutropenia was verified. Results showed that the assay is linear under SOP conditions, and that the in vitro endpoints used by the clinical prediction model of neutropenia are highly reproducible within and between laboratories. Valid tests represented 95% of all tests attempted. The 90% inhibitory concentration values (IC(90)) from Test A and Test B accurately predicted the human maximum tolerated dose (MTD) for five of six and for four of six myelosuppressive anticancer drugs, respectively, that were selected as prototype xenobiotics. As expected, both tests failed to accurately predict the human MTD of a drug that is a likely protoxicant. It is concluded that Test A offers significant cost advantages compared to Test B, without any loss of performance or predictive accuracy. On the basis of these results, we proposed a formal Phase II validation study using the Test A SOP for 16-18 additional

Mutations in the ELA2 gene encoding neutrophil elastase are present in most patients with sporadic severe congenital neutropenia but only in some patients with the familial form of the disease.

Severe congenital neutropenia (SCN) was originally described as an autosomal recessive disorder. Subsequently, autosomal dominant and sporadic forms of the disease have been recognized. All forms are manifest by persistent severe neutropenia and recurrent bacterial infection. In contrast, cyclical hematopoiesis is characterized by periodic neutropenia inter-spaced with (near) normal neutrophil counts. Recently, linkage analysis on 13 affected pedigrees identified chromosome 19p13.3 as the likely position for mutations in cyclical hematopoiesis. Heterozygous mutations in the ELA2 gene encoding neutrophil elastase were detected in all families studied. Further work also demonstrated mutations in ELA2 in sporadic and autosomal dominant SCN. However, all mutations described to date are heterozygous and thus appear to act in a dominant fashion, which is inconsistent with an autosomal recessive disease. Therefore, the current study investigated whether mutations in ELA2 could account for the disease phenotype in classical autosomal recessive SCN and in the sporadic and autosomal dominant types. All 5 exons of ELA2 and their flanking introns were studied in 18 patients (3 autosomal recessive, 5 autosomal dominant [from 3 kindreds], and 10 sporadic) using direct automated sequencing. No mutations were found in the autosomal recessive families. A point mutation was identified in 1 of 3 autosomal dominant families, and a base substitution was identified in 8 of 10 patients with the sporadic form, though 1 was subsequently shown to be a low-frequency polymorphism. These results suggest that mutations in ELA2 are not responsible for classical autosomal recessive Kostmann syndrome but provide further evidence for the role of ELA2 in SCN.

International guidelines recommend routine microbiological assessment of patients with febrile neutropenia, but do not recommend a change from broad-spectrum antibiotic therapy to pathogen-specific therapy when a clinically relevant organism has been isolated. The aim of the study was to determine the aetiology of febrile neutropenia in adult haematology patients at Auckland City Hospital, to document the changes in treatment made following isolation of a clinically relevant organism and to assess adverse outcomes in any patient who received pathogen-specific therapy after a positive culture result. The results of all microbiological tests together with antibiotic therapy were recorded from consecutive patients with fever and a neutrophil count cultures in 40 episodes: Gram-positive cocci accounted for 46% of isolates and Gram-negative bacilli for 35%. Isolation of a pathogen from blood cultures resulted in a change of treatment in 25 of 40 (62.5%, 95%CI 46-77%) episodes. In 12 of these episodes, antibiotic therapy was optimized to a single pathogen-specific agent. No adverse events or subsequent changes in antibiotic therapy occurred in any of these 12 patients. Isolation of a pathogen from specimens other than blood seldom led to a change in therapy. Isolation of a pathogen from blood cultures often allows antibiotic therapy to be simplified to a pathogen-specific regimen. Further study of this approach is warranted.

In 51 patients (atomic bomb survivors 50, unexposed persons 1) who have had neutropenia for two years or more under indistinct cause, cell surface antigen was analyzed by flow cytometry. Twenty-nine cases of survivors were diagnosed as NK cell leukemia or NK cell cytosis because analysis data showed CD3(-), CD56(+) and CD57(+/-). Six cases were diagnosed as NK like T cell hypercytosis because analysis data showed CD3(+), CD56(+/-) and CD57(+). As for 15 cases, CD56(+) cell number was in range of 15.96{+-}5.35 of a normal person, and no relation with NK cell was recognized. But, CD4/CD8 ratio was higher than 2.1, and gain of T helper cell was recognized. One unexposed persons was diagnosed as chronic NK cell leukemia because analysis data showed CD3(-), CD56(+) and CD57(+). Anti-neutrophil antibody wasn't recognized. Cytotoxic activity for K562 and Raji cell line showed high value compared with that of a normal person. Epstein Barr virus wasn't detected. (K.H.)

Nivestim™ (filgrastim) is a follow-on biologic agent licensed in the EU for the treatment of neutropenia and febrile neutropenia induced by myelosuppressive chemotherapy. Nivestim™ has been studied in phase 2 and 3 clinical trials where its efficacy and safety was found to be similar to its reference product, Neupogen ® . Follow-on biologics continue to be scrutinised for safety. We present a design for two observational phase IV studies that are evaluating the safety profile of Nivestim™ for the prevention and treatment of febrile neutropenia (FN) in patients treated with cytotoxic chemotherapy in general clinical practice. The NEXT (Tolérance de Nivestim chez les patiEnts traités par une chimiothérapie anticancéreuse cytotoXique en praTique courante) and VENICE (VErträglichkeit von NIvestim unter zytotoxischer Chemotherapie in der Behandlung malinger Erkrankungen) trials are multicentre, prospective, longitudinal, observational studies evaluating the safety profile of Nivestim™ in 'real-world’ clinical practice. Inclusion criteria include patients undergoing cytotoxic chemotherapy for malignancy and receiving Nivestim as primary or secondary prophylaxis (NEXT and VENICE), or as treatment for ongoing FN (NEXT only). In accordance with European Union pharmacovigilance guidelines, the primary objective is to evaluate the safety of Nivestim™ by gathering data on adverse events in all system organ classes. Secondary objectives include obtaining information on patient characteristics, efficacy of Nivestim™ therapy (including chemotherapy dose intensity), patterns of use of Nivestim™, and physician knowledge regarding filgrastim prescription and the reasons for choosing Nivestim™. Data will be gathered at three visits: 1. At the initial inclusion visit, 2. At a 1-month follow-up visit, and 3. At the end of chemotherapy. Recruitment for VENICE commenced in July 2011 and in November 2011 for NEXT. VENICE completed recruitment in July 2013 with

Febrile neutropenia (FN) and infection-related mortality are major problems for children with cancer in low-income countries. Identifying predictors for adverse outcome of FN in low-income countries permits targeted interventions. We describe the nature and predictors of microbiologically documented infection (MDI) and mortality of FN in children with cancer in El Salvador. We examined Salvadoran pediatric oncology patients admitted with FN over a 1-year period. Data were collected prospectively. Demographic, treatment, and admission-related variables were examined as predictors of outcomes. Hundred six FN episodes among 85 patients were included. Twenty-three of 106 episodes (22%) were microbiologically documented; 13 of 106 episodes (12%) resulted in death. Gram-positive and gram-negative organisms were isolated in 14 of 23 and 11 of 23 specimens; polymicrobial infections were common (11 of 23 episodes of MDI). Older age decreased the MDI risk [odds ratio (OR) per year=0.87, 95% confidence interval (CI), 0.75-0.99; P=0.04] while increasing number of days since the last chemotherapy increased the risk (OR=1.03 per day, 95% CI, 1.01-1.04; P=0.002). Pneumonia diagnosed either clinically (OR=6.6, 95% CI, 1.8-30.0; P=0.005) or radiographically (OR=5.5, 95% CI, 1.7-18.1; P=0.005) was the only predictor of mortality. In El Salvador, polymicrobial infections were common. Pneumonia at admission identified children with FN at high risk of death; these children may benefit from targeted interventions.

Terrorist attacks involving radiological or nuclear weapons are a substantial geopolitical concern, given that large populations could be exposed to potentially lethal doses of radiation. Because of this, evaluating potential countermeasures against radiation-induced mortality is critical. Gut microflora are the most common source of systemic infection following exposure to lethal doses of whole-body radiation, suggesting that prophylactic antibiotic therapy may reduce mortality after radiation exposure. The chemical stability, easy administration and favorable tolerability profile of the non-systemic antibiotic, rifaximin, make it an ideal potential candidate for use as a countermeasure. This study evaluated the use of rifaximin as a countermeasure against low-to-intermediate-dose whole-body radiation in rodents. Female Wistar rats (8 weeks old) were irradiated with 550 cGy to the whole body and were evaluated for 30 d. Animals received methylcellulose, neomycin (179 mg/kg/d) or variably dosed rifaximin (150-2000 mg/kg/d) one hour after irradiation and daily throughout the study period. Clinical assessments (e.g. body weight) were made daily. On postirradiation day 30, blood samples were collected and a complete blood cell count was performed. Animals receiving high doses of rifaximin (i.e. 1000 or 2000 mg/kg/d) had a greater increase in weight from the day of irradiation to postirradiation day 30 compared with animals that received placebo or neomycin. For animals with an increase in average body weight from irradiation day within 80-110% of the group average, methylcellulose rendered an absolute neutrophil count (ANC) of 211, neomycin rendered an ANC of 334, rifaximin 300 mg/kg/d rendered an ANC of 582 and rifaximin 1000 mg/kg/d rendered an ANC of 854 (P = 0.05 for group comparison). Exposure to rifaximin after near-lethal whole-body radiation resulted in diminished levels of neutropenia.

Full Text Available Objetivo: Determinar el riesgo familiar total de las familias con mujeres diagnosticadas con cáncer de mama, que asisten a un centro de salud oncológico en la ciudad de Barranquilla. Materiales y Métodos: El estudio fue de tipo descriptivo, transversal con abordaje cuantitativo. Se utilizó el instrumento Riesgo Familiar Total RFT 5-33. El universo estuvo conformado por familias con mujeres diagnosticadas con cáncer en mama. La muestra fue de 41 familias que integraron a 154 miembros; se abordó el estudio de manera censal, y no por medio de una muestra, porque el acceso a la información de la totalidad de las familia fue viable. Resultados: Los resultados mostraron que las familias, en su mayoría, son de tipo 2. El 68 % de las pacientes categorizan sus familias como amenazadas, el 5 % como familias de alto riesgo y un 27 % de las familias con un bajo riesgo. Conclusiones: Los hallazgos encontrados en esta investigación son importantes para las familias, lo cual permitirá establecer acciones y actividades que logren orientar e implementar procesos de atención específicos con el propósito de cuidar a las familias para que se mantengan sanos en un nivel de bajo riesgo; además, desarrollar controles y seguimiento a aquellas familias que se encuentran en un riesgo alto de amenazas, mediante acciones de promoción y prevención de la enfermedad de una manera amplia. Por lo anterior, se deben emprender programas más agresivos de prevención y promoción, especialmente con las familias que asisten en busca de apoyo médico para este padecimiento; de esta forma, se podrán diagnosticar los casos de forma temprana y proceder al respectivo tratamiento.

Full Text Available Se presenta un estudio sobre la reducción catalítica selectiva (RCS de NOx con metano en presencia de oxígeno en exceso con varios catalizadores a base de las zeolitas mordenita, ferrierita y ZSM-5 intercambiadas con diferentes cargas de cobalto y con las correspondientes zeolitas en forma acida. Cuando la mezcla reactiva contenía mayormente NO2 en lugar de NO, los catalizadores ácidos mostraron las más altas velocidades de formación de N2 en condiciones secas. Las mayores actividades se obtuvieron con los catalizadores Co-mordenita, siguiendo en orden de actividad los catalizadores Co-Ferrierita y Co-ZSM-5. El catalizador Co-Mordenita más activo se ensayó con una mezcla reactiva donde predominó el NO en lugar del NO2 bajo condiciones secas e hidrotérmicas y en presencia de SO2. Con la adición de 8% de agua a la mezcla de reacción se observó desactivación reversible, especialmente a bajas temperaturas. La adición de 60 ppm de SO2 disminuyó la velocidad de reacción aproximadamente a la mitad debido posiblemente al envenenamiento de algunos sitios activos.

Game of clones: the genomic evolution of severe congenital neutropenia.

Science.gov (United States)

Touw, Ivo P

2015-01-01

Severe congenital neutropenia (SCN) is a genetically heterogeneous condition of bone marrow failure usually diagnosed in early childhood and characterized by a chronic and severe shortage of neutrophils. It is now well-established that mutations in HAX1 and ELANE (and more rarely in other genes) are the genetic cause of SCN. In contrast, it has remained unclear how these mutations affect neutrophil development. Innovative models based on induced pluripotent stem cell technology are being explored to address this issue. These days, most SCN patients receive life-long treatment with granulocyte colony-stimulating factor (G-CSF, CSF3). CSF3 therapy has greatly improved the life expectancy of SCN patients, but also unveiled a high frequency of progression toward myelodysplastic syndrome (MDS) and therapy refractory acute myeloid leukemia (AML). Expansion of hematopoietic clones with acquired mutations in the gene encoding the G-CSF receptor (CSF3R) is regularly seen in SCN patients and AML usually descends from one of these CSF3R mutant clones. These findings raised the questions how CSF3R mutations affect CSF3 responses of myeloid progenitors, how they contribute to the pre-leukemic state of SCN, and which additional events are responsible for progression to leukemia. The vast (sub)clonal heterogeneity of AML and the presence of AML-associated mutations in normally aged hematopoietic clones make it often difficult to determine which mutations are responsible for the leukemic process. Leukemia predisposition syndromes such as SCN are unique disease models to identify the sequential acquisition of these mutations and to interrogate how they contribute to clonal selection and leukemic evolution. © 2015 by The American Society of Hematology.

2017-01-01

Full Text Available Background: Invasive aspergillosis (IA is an increasingly common and fatal opportunistic fungal infection in patients with haematological diseases. Early diagnosis is difficult as mycological culture techniques have low sensitivity and the radiological tools have low specificity. Galactomannan enzyme immunoassay (GEI detects galactomannan in the human serum with a reported sensitivity and specificity between 30% and 100%. Aims: The aim of this study was to analyse the role of GEI in diagnosis of IA in patients with febrile neutropenia and to evaluate the role of GEI in the diagnosis of IA as per the revised (2008 European Organization for Research and Treatment of Cancer–Mycoses Study Group (EORTC–MSG criteria at two different optical density (OD cut-offs of 0.5 and 1.0. Setting: This prospective study was conducted in Safdarjung Hospital, New Delhi, India. Methods: GEI testing was performed in adult patients of febrile neutropenia with evidence of IA. Results at two different OD indices (ODIs of 0.5 and 1.0 were analysed. The evaluation of the diagnostic parameter, that is, GEI was measured in terms of sensitivity, specificity and positive and negative predictive value and was validated with the revised (2008 EORTC–MSG diagnostic criteria of IA. Results: One hundred and eleven patients had evidence of IA, of which 79 patients were GEI positive when cut-off ODI was 0.5, whereas with cut-off ODI 1.0, 55 patients were GEI positive. Conclusion: ODI of 1.0 should be considered as positive while in patients with OD between 0.5 and 1.0, repeat sampling from the patient is recommended.

However, high variability of these mutations has been reported. This study was designed to describe the analysis of the ELA2 gene, clinical manifestations and demographic characteristics in patients with CN and SCN.Methods: A series of 21 patients with CN or SCN were selected, based on SCINR criteria, from the immunology ward of the Pediatric Medicine Center, Tehran, Iran, from March 2004 to August 2005. The ELA2 gene, isolated from blood samples, was analyzed using RT-PCR and automated capillary sequencing. Informed consent was obtained under the tenets of the Helsinki Declaration and the Ethical Committee of the Tehran University of Medical Sciences.Results: Kostmann's syndrome and CN was diagnosed in three and 18 patients respectively. Of all the patients, one or two mutations were found in 18 cases (85.7%, including all three patients with SCN and 15 of the patients with CN. Exons two and four had the most mutations (eight and seven cases, respectively. Seven patients had double mutations in two distinct exons. Overall, 16 different mutations were found. At the time of presentation, the mean age of patients was 13.4 ±17.6 months, ranging from one month to seven years. Overall, 61.9% of patients had consanguineous parents. The mean absolute neutrophil count was 830.5 ±419.4 (150-2000/mm3. On average, each patient had been admitted to the hospital 2.2 ±1.6 times. The neutrophil counts of the SCN patients were significantly higher than those of the CN patients. However, there was no significant difference in the neutrophil counts between patients with mutations and those without mutations. All patients with SCN had two or more infectious complications, although the prevalence of infectious or non-infectious complications did not correlate with ELA2 mutations or the

Full Text Available OBJETIVO: Antibióticos são os medicamentos que mais causam eventos adversos, gerando problemas aos pacientes e custos adicionais ao sistema de saúde. Assim, objetivou-se analisar a ocorrência de eventos adversos a antibióticos em pacientes internados em um hospital. MÉTODOS: Realizou-se monitoramento intensivo do uso de antibióticos em pacientes adultos internados no município de Maringá, Paraná, de setembro de 2002 a fevereiro de 2003. Foram pesquisadas variáveis relativas aos medicamentos em uso, em particular aos antibióticos e aos eventos adversos. Com base em critérios para a avaliação do uso correto dos antibióticos, os eventos observados foram classificados como reações adversas, erros de medicação e "quase erros". Para relação de causalidade entre a administração do fármaco e o surgimento dos eventos utilizou-se o algoritmo de Naranjo. RESULTADOS: Foram acompanhados 87 pacientes e identificados 91 eventos adversos, sendo três deles (3,3% reações adversas a medicamentos, sete (7,7% erros de medicação, e 81 (89,0% "quase erros". As reações a medicamentos ocorreram devido ao uso de quinolonas e foram consideradas "prováveis" utilizando-se o algoritmo de Naranjo. Os sete erros de medicação ocorreram devido a quatro prescrições incorretas de dose e três interações medicamentosas. CONCLUSÕES: Os resultados sugerem que a falta de conhecimento do medicamento ou a falta de informação sobre o paciente no momento da prescrição tenham sido os principais fatores envolvidos na ocorrência das reações a medicamentos.OBJECTIVE: Antibiotics are the most common drugs causing adverse events and they lead to problems to patients and additional costs of the health system.

Full Text Available La mastopexia con implantes de silicona, es uno de los procedimientos más frecuentes en la práctica diaria en Cirugía Plástica. Sin embargo, la pobre calidad de la cobertura de las mamas, relacionada con piel estriada, escaso tejido subcutáneo y pérdida del parénquima mamario secundarios a la lactancia prolongada y a la pérdida masiva de peso, son causa del incremento progresivo de resultados insatisfactorios a medio y largo plazo que han sido evaluados, analizados y discutidos por los especialistas. Los resultados insatisfactorios más frecuentes en mastopexia con implantes en posición retromuscular son: doble contorno mamario, asimetrías y desplazamiento de los implantes. Los objetivos del presente estudio son: describir el nuevo método triplanar como alternativa útil para lograr mejores resultados en pacientes con mala calidad de cobertura y analizar los resultados obtenidos con el mismo. Realizamos un estudio observacional, descriptivo, prospectivo, en un grupo de 268 pacientes con diagnóstico de ptosis mamaria con hipotrofia y mala calidad de cobertura por piel estriada, escaso tejido celular subcutáneo y pérdida del parénquima mamario, secundarios a lactancia prolongada y pérdida masiva de peso, entre otros, a las que se les practicó mamoplastia de aumento con implantes de silicona mediante la aplicación del método triplanar descrito por la autora, entre enero del 2004 y enero del 2013 en el Hospital de Bocagrande de Cartagena, Colombia. El diseño de la técnica se basa en los principios de cicatriz vertical descrita por Lassus o Lejour o mediante cicatriz en "J", descrita por la autora. El método triplanar se basa en tres planos de cobertura del implante. Plano I: submuscular, para cubrir los dos tercios superiores del implante. Plano II: colgajo dermoglandular con dos prolongaciones distales triangulares de tejido adiposo, en forma de pez, para cubrir el tercio inferior del implante y el borde libre del m

Neutropenia Prediction Based on First-Cycle Blood Counts Using a FOS-3NN Classifier

Directory of Open Access Journals (Sweden)

Elize A. Shirdel

2011-01-01

Full Text Available Background. Delivery of full doses of adjuvant chemotherapy on schedule is key to optimal breast cancer outcomes. Neutropenia is a serious complication of chemotherapy and a common barrier to this goal, leading to dose reductions or delays in treatment. While past research has observed correlations between complete blood count data and neutropenic events, a reliable method of classifying breast cancer patients into low- and high-risk groups remains elusive. Patients and Methods. Thirty-five patients receiving adjuvant chemotherapy for early-stage breast cancer under the care of a single oncologist are examined in this study. FOS-3NN stratifies patient risk based on complete blood count data after the first cycle of treatment. All classifications are independent of breast cancer subtype and clinical markers, with risk level determined by the kinetics of patient blood count response to the first cycle of treatment. Results. In an independent test set of patients unseen by FOS-3NN, 19 out of 21 patients were correctly classified (Fisher’s exact test probability P<0.00023 [2 tailed], Matthews’ correlation coefficient +0.83. Conclusions. We have developed a model that accurately predicts neutropenic events in a population treated with adjuvant chemotherapy in the first cycle of a 6-cycle treatment.

Severe congenital neutropenia is an inherited disease characterized by low peripheral blood neutrophils, amenable to bone marrow transplantation. Genetic analysis in the family here described detected a ELA2 splice-site mutation in the affected child and also in his asymptomatic father. The parents requested preimplantation genetic diagnosis (PGD), coupled with HLA matching, to obtain a suitable bone marrow donor for the affected child. A PGD protocol was developed, based on multiplex nested PCR for direct analysis of the ELA2 mutation, flanking polymorphic markers and HLA typing. The amplification efficiency of the mutation was > 90% in single leukocytes from the affected child but only 67% in the father. Analysis of single haploid sperm cells from the father demonstrated three different sperm-cell populations: (1) sperm cells harboring the ELA2 mutation on the 'affected' haplotype, (2) sperm cells without the ELA2 mutation on the 'normal' haplotype, and (3) sperm cells without the ELA2 mutation on the 'affected' haplotype. These data demonstrate that the ELA2 mutation in the father occurred de novo during his embryonic development, resulting in somatic as well as germ-line mosaicism. This conclusion was also taken into consideration when PGD was performed. Copyright (c) 2010 John Wiley & Sons, Ltd.

Pegfilgrastim is widely used for the prevention of chemotherapy-induced neutropenia. In highly regulated markets, there are currently no approved biosimilars of pegfilgrastim. Pegfilgrastim Randomized Oncology (Supportive Care) Trial to Evaluate Comparative Treatment (PROTECT-2) was a confirmatory efficacy and safety study designed to compare proposed biosimilar LA-EP2006 with reference pegfilgrastim (Neulasta, Amgen) in early-stage breast cancer patients receiving adjuvant or neoadjuvant myelosuppressive chemotherapy. A total of 308 patients were randomized to LA-EP2006 or reference pegfilgrastim. Each patient received TAC (intravenous docetaxel 75 mg/m(2), doxorubicin 50 mg/m(2), and cyclophosphamide 500 mg/m(2)) on day 1 of each cycle, for six or more cycles. Pegfilgrastim (LA-EP2006 or reference) was given subcutaneously (6 mg in 0.6 mL) on day 2 of each cycle. The primary endpoint was duration of severe neutropenia (DSN) during cycle 1 (number of consecutive days with an absolute neutrophil count prevention of neutropenia in patients with early-stage breast cancer receiving TAC. The granulocyte colony-stimulating factor pegfilgrastim is widely used for the prevention of chemotherapy-induced neutropenia. Biosimilars are biologics with similar quality, safety, and efficacy to a reference product that may increase the affordability of treatment compared with their reference compounds. There are currently no approved biosimilars of pegfilgrastim in highly regulated markets. No previous phase III studies have been performed with LA-EP2006. PROTECT-2 was conducted to confirm the similarity of the proposed biosimilar LA-EP2006 to pegfilgrastim. Biosimilar pegfilgrastim (LA-EP2006) may benefit oncology patients by offering increased access to biological treatments that may improve clinical outcomes. This means that patients could potentially be treated prophylactically with biologics rather than only after complications have occurred. ©AlphaMed Press.

Para comprender qué se entiende por investigación inclusiva tenemos que remontarnos a los debates epistemológicos sobre las metodologías cuantitativas y cualitativas, acontecidos en la década de los 90, en torno a la revista Disability & Society. A partir de una síntesis de dichos debates, focalizados en el ámbito de la «discapacidad intelectual y del desarrollo», se exponen dos estrategias de colaboración con dicha población: a una aproximación etnográfica (de trabajo grupal, y b una aproximación biográfica (de trabajo individual. A continuación se esboza un posible diseño de trabajo de campo que intenta superar el paradigma cualitativo «clásico» con el objetivo de incluir a dicho colectivo más allá del rol de «sujetos de la investigación».

Genetic Associations in Acquired Immune-Mediated Bone Marrow Failure Syndromes: Insights in Aplastic Anemia and Chronic Idiopathic Neutropenia

Mavroudi, Irene; Papadaki, Helen A.

2012-01-01

Increasing interest on the field of autoimmune diseases has unveiled a plethora of genetic factors that predispose to these diseases. However, in immune-mediated bone marrow failure syndromes, such as acquired aplastic anemia and chronic idiopathic neutropenia, in which the pathophysiology results from a myelosuppressive bone marrow microenvironment mainly due to the presence of activated T lymphocytes, leading to the accelerated apoptotic death of the hematopoietic stem and progenitor cells, such genetic associations have been very limited. Various alleles and haplotypes of human leucocyte antigen (HLA) molecules have been implicated in the predisposition of developing the above diseases, as well as polymorphisms of inhibitory cytokines such as interferon-γ, tumor necrosis factor-α, and transforming growth factor-β1 along with polymorphisms on molecules of the immune system including the T-bet transcription factor and signal transducers and activators of transcription. In some cases, specific polymorphisms have been implicated in the outcome of treatment on those patients. PMID:22956967

Pediatric oncology patients are at an increased risk of invasive bacterial infection due to immunosuppression. The risk of such infection in the absence of severe neutropenia (absolute neutrophil count ≥ 500/μL) is not well established and a validated prediction model for blood stream infection (BSI) risk offers clinical usefulness. A 6-site retrospective external validation was conducted using a previously published risk prediction model for BSI in febrile pediatric oncology patients without severe neutropenia: the Esbenshade/Vanderbilt (EsVan) model. A reduced model (EsVan2) excluding 2 less clinically reliable variables also was created using the initial EsVan model derivative cohort, and was validated using all 5 external validation cohorts. One data set was used only in sensitivity analyses due to missing some variables. From the 5 primary data sets, there were a total of 1197 febrile episodes and 76 episodes of bacteremia. The overall C statistic for predicting bacteremia was 0.695, with a calibration slope of 0.50 for the original model and a calibration slope of 1.0 when recalibration was applied to the model. The model performed better in predicting high-risk bacteremia (gram-negative or Staphylococcus aureus infection) versus BSI alone, with a C statistic of 0.801 and a calibration slope of 0.65. The EsVan2 model outperformed the EsVan model across data sets with a C statistic of 0.733 for predicting BSI and a C statistic of 0.841 for high-risk BSI. The results of this external validation demonstrated that the EsVan and EsVan2 models are able to predict BSI across multiple performance sites and, once validated and implemented prospectively, could assist in decision making in clinical practice.

Full Text Available El síndrome confusional agudo (SCA o delirium en pacientes hospitalizados es un problema frecuente y grave. Se caracteriza por síntomas de comienzo agudo y curso fluctuante con inatención, pensamiento desorganizado, y con distintos niveles de alteración de la conciencia.En la bibliografía consultada, el SCA como manifestación de un síndrome de abstinencia aguda nicotínica fue descripto en solo ocho casos. Presentamos el caso de un tabaquista grave que, internado por una reagudización de su enfermedad pulmonar obstructiva crónica (EPOC, presentó un cuadro de SCA al tercer día de abstinencia tabacal, cediendo los síntomas tras la administración de un parche de nicotina. Lo descripto sugiere que en pacientes internados que presentan SCA y agitación, con fuertes antecedentes de tabaquismo, un simple ensayo con un parche de nicotina puede ofrecer en pocas horas una notable respuesta terapéutica y a su vez un test confirmatorio. El reconocimiento del SCA como forma de presentación de la abstinencia nicotínica permitirá identificar casos habitualmente complejos en los que se podrá implementar una sencilla y eficaz alternativa terapéutica.Delirium or acute confusional state among hospitalized patients is a frequent and serious problem. It is characterized by acute onset symptoms, fluctuating course, impaired attention, unorganized thinking, and altered level of conciousness. Delirium, as a manifestation of acute nicotine withdrawal syndrome has been reported in the reviewed literature only in eight cases. We report the case of a heavy smoker admitted because of a reagudization of his chronic obstructive pulmonary disease. At the third day of nicotine abstinence, he developed delirium with a rapid improvement of his symptoms after treatment with a transdermal nicotine patch. This description suggests that in hospitalized heavy smokers who develop delirium with agitation, a simple trial with a nicotine patch can offer a dramatic

Development of the pros and cons of intraperitoneal (IP) chemotherapy in the treatment of epithelial ovarian cancer based on the most prominent data published on the evolution of IP chemotherapy and on experience with this therapeutic strategy in clinical routine. The literature published on IP chemotherapy in ovarian cancer between 1970 and 2008 was identified systematically by computer-based searches in MEDLINE and the Cochrane Library. Furthermore, a preliminary analysis of data recorded during an observational nationwide multicenter study of the Austrian AGO on IP-IV chemotherapy using the GOG-172 treatment regimen was performed. The literature review unequivocally revealed a significantly greater toxicity for IP than for intravenous (IV) cisplatin-based chemotherapy. However, according to a Cochrane meta-analysis, IP-IV administration of chemotherapy is associated with a 21.6% decrease in the risk for death. In agreement with earlier reports, the most frequently mentioned side-effects in the Austria-wide observational study were long-lasting neurotoxicity, abdominal pain, fatigue, gastrointestinal and metabolic toxicities, and catheter-related complications. Most of these toxicities were identified as mirroring the toxicity profile of high-dose IV cisplatin (>or=100 mg/m(2)). In some patients, the classic IP-IV regimen with cisplatin/paclitaxel was changed to an alternative schedule comprising carboplatin AUC 5 (d1) and weekly paclitaxel 60 mg/m(2) (d1, 8, 15) completely administered via the IP route. This treatment was better tolerated and quality of life was significantly less compromised. However, neutropenia and thrombocytopenia were the limiting side-effects of this IP regimen.

This study aimed to describe severe infections with extensively drug-resistant Acinetobacter baumannii-calcoaceticus complex (XDR-ABC), as well as to investigate risk factors for mortality, in cancer patients. It was a retrospective study including all patients diagnosed with XDR-ABC bacteraemia during hospitalization in the intensive care unit of a cancer hospital between July 2009 and July 2013. Surveillance cultures were collected weekly during the study period, and clonality was analysed using pulsed field gel electrophoresis (PFGE). We analysed underlying diseases, oncology therapy, neutrophil counts, infection site and management of infection, in terms of their correlation with 30-day mortality. During the study period, 92 patients with XDR-ABC bacteraemia were identified, of whom 35 (38.0%) were patients with haematological malignancy. We identified XDR-ABC strains with four different profile patterns, 91.3% of patients harbouring the predominant PFGE type. Of the 92 patients with XDR-ABC bacteraemia, 66 (71.7%) had central line-associated bloodstream infections; infection occurred during neutropenia in 22 (23.9%); and 58 (63.0%) died before receiving the appropriate therapy. All patients were treated with polymyxin, which was used in combination therapy in 30 of them (32.4%). The 30-day mortality rate was 83.7%. Multivariate analysis revealed that septic shock at diagnosis of XDR-ABC infection was a risk factor for 30-day mortality; protective factors were receiving appropriate therapy and invasive device removal within the first 48 h. Among cancer patients, ineffective management of such infection increases the risk of death, more so than do features such as neutropenia and infection at the tumour site.

Anti-human neutrophil antigen (HNA) antibodies have been implicated in the development of neonatal alloimmune neutropenia (NAN) and autoimmune neutropenia (AIN). There are many conventional assay methods that detect anti-HNA antibodies. However, a method to measure multiple samples and detect several anti-HNA antibodies simultaneously is needed. We developed a new method, the extracted granulocyte antigen immunofluorescence assay (EGIFA), to analyze anti-HNA-1a, -1b, and -2 antibodies in sera. The results obtained by EGIFA were evaluated in comparison with those from several standard assay methods. Anti-HNA antibodies in serum samples from nine familial cases with suspected NAN (n = 19) and children with suspected AIN (n = 88) were also measured by EGIFA. The evaluation of nine serum samples with anti-HNA antibodies suggested that EGIFA demonstrated equivalent specificity and superior sensitivity to monoclonal antibody-specific immobilization of granulocyte antigens and had comparable sensitivity to the granulocyte indirect immunofluorescence test. EGIFA successfully detected anti-HNA-1a or -1b antibodies in seven of nine familial cases with suspected NAN. EGIFA detected anti-HNA antibodies in 40.9% of children with suspected AIN. Among them, isolated anti-HNA-1a or -1b antibody was detected in 4.5 or 12.5% of children, respectively, and anti-HNA-2 antibody was identified in 3.4% of children. The 30.8% (16 of 52) of children negative for anti-HNA antibody by EGIFA were positive for anti-HLA antibody. EGIFA facilitated the measurement of anti-HNA-1a, -1b, and/or -2 antibodies in sera. The prompt measurement of anti-HNA antibodies will improve the diagnosis and clinical management of patients with suspected NAN or AIN. © 2017 AABB.

RadCon: A Radiological Consequences Model

International Nuclear Information System (INIS)

Crawford, J.; Domel, R.U.

2000-05-01

RadCon estimates the dose received by user selected groups in the population from an accidental release of radionuclides to the environment. The exposure pathways considered are external exposure from the cloud and ground and internal exposure from inhalation and ingestion of contaminated food. Atmospheric dispersion modelling is carried out externally to RadCon.Given a two dimensional time varying air and ground concentration of radioactive elements, RadCon allows the user to: view the air and ground concentration over the affected area, select optional parameters and calculate the dose to people,display the results to the user, and change the parameter values. RadCon offers two user interfaces: 1) the standard graphical user interface which is started using Java DoseApp at the command line, or by setting up a shortcut to this command (particularly when RadCon is installed on a PC) and 2) the text based interface used to generate information for the model inter-comparison exercise . This is initiated using Java BIOMASS at the command line, or an equivalent shortcut. The text based interface was developed for research purposes and is not generally available. Appendices A, B and C provide a summary of instructions on setting up RadCon. This will generally be carried out by the computer support personnel

1998-09-01

Prepubertal periodontitis affects both primary and permanent dentition. The purpose of this study was to examine the composition of subgingival microflora of the permanent dentition in an 11-year-old Caucasian female, who had premature exfoliation of her deciduous teeth on her 5th year of age, and the response of this condition to the antibiotic therapy and supportive periodontal care. Gingival tissues were highly inflamed and alveolar bone loss was detected radiographically. The girl had experienced frequent upper respiratory tract infections, tonsilitis and recurrent otitis media. Her mother had history of early onset periodontitis associated with chronic idiopathic neutropenia. Blood chemistry tests and immunological examinations were also performed. Subgingival plaque samples were collected from the proximal sites of permanent molars, incisors, canines and maxillary premolars. 27 different microbial species were isolated from the subgingival microflora. Among the predominant species were Porphyromonas gingivalis (17.6%-7.3%), Prevotella intermedia (12.4%-4.7%), Capnocytophaga sputigena (14.4%-10.4%), Capnocytophaga ochracea (13.2%-6.9%) and Actinobacillus actinomycetemcomitans (9.3%-5.5%). Periodontal treatment consisted of scaling, root planing in conjunction with antibiotic administration of Augmentin 312.5 mg and Flagyl 200 mg, each t.i.d. for 10 days. 3 weeks after the antibiotic therapy, bacterial samples were collected from the same sites. All the periodontal pathogens were recovered in lower levels and A.actinomycetemcomitans was almost eliminated in the 3-week period. The evaluation of clinical indices at 3, 6 and 12 months showed that periodontal treatment in conjunction with antibiotics was effective and rapidly followed by marked clinical improvement. The microbiological monitoring at 3, 6 and 12 months after antibiotic treatment and each time prior to supportive periodontal care, revealed that the periodontal pathogens fluctuated in low levels even

Full Text Available Fundamento: el melanoma es el más terrible y mortífero de los cánceres de piel. Se origina frecuentemente a partir de un nevo melanocítico con riesgo de transformación maligna. Estas lesiones pigmentadas se diagnostican cada vez más en edades tan tempranas como la adolescencia. Objetivo: caracterizar los pacientes en edades pediátricas con signos de lesiones pigmentarias de la piel con riesgo de transformación maligna. Métodos: se realizó un estudio prospectivo de corte transversal en un grupo de 50 pacientes en edades entre 5 y 19 años, que asistieron a la consulta de dermatología del Hospital Pediátrico de Centro Habana en el año 2010, con signos de lesiones pigmentarias de la piel con riesgo de transformación maligna. Se aplicó un instrumento de recogida de datos, con previo consentimiento informado. Se utilizó la estadística descriptiva para el procesamiento de los datos. Resultados: en la población de estudio predominó la adolescencia temprana, el grupo de riesgo con daño actínico crónico y el fototipo III. Estuvo presente el antecedente familiar de cáncer de piel no-melanoma. La lesión más frecuente fue la de nevo melanocítico displásico. Además, se reportó un caso de carcinoma basal en paciente de fototipo II, perteneciente al grupo de riesgo de xeroderma pigmentoso. Conclusiones: se evidenció la transformación maligna de lesiones pigmentarias en piel de pacientes de grupos de riesgo.

Concanavalin-A (Con-A) hepatitis is regarded as a T cell-mediated model of acute liver injury. Mincle is a C-type lectin receptor (CLR) that is critical in the immune response to mycobacteria and fungi, but does not have a well-defined role in pre-clinical models of non-pathogen mediated inflammation. Since Mincle can ligate the cell death ligand SAP130, we postulated that Mincle signaling drives intrahepatic inflammation and liver injury in Con-A hepatitis. Acute liver injury was assessed in the murine Con-A hepatitis model using C57BL/6, Mincle−/−, and Dectin-1−/− mice. The role of C/EBPβ and HIF-1α signaling was assessed using selective inhibitors. We found that Mincle was highly expressed in hepatic innate inflammatory cells and endothelial cells in both mice and humans. Furthermore, sterile Mincle ligands and Mincle signaling intermediates were increased in the murine liver in Con-A hepatitis. Most significantly, Mincle deletion or blockade protected against Con-A hepatitis whereas Mincle ligation exacerbated disease. Bone marrow chimeric and adoptive transfer experiments suggested that Mincle signaling in infiltrating myeloid cells dictates disease phenotype. Conversely, signaling via other CLRs did not alter disease course. Mechanistically, we found that Mincle blockade decreased the NF-κβ related signaling intermediates, C/EBPβ and HIF-1α, both of which are necessary in macrophage-mediated inflammatory responses. Accordingly, Mincle deletion lowered production of nitrites in Con-A hepatitis and inhibition of both C/EBPβ and HIF1-α reduced the severity of liver disease. Our work implicates a novel innate immune driver of Con-A hepatitis and, more broadly, suggests a potential role for Mincle in diseases governed by sterile inflammation. PMID:27559045

Casi la generalidad de los estudios realizados sobre cementos con adición de cenizas volantes se refieren a sus características y comportamiento en pastas, morteros y hormigones, siempre en relación con aquéllos del cemento portland. Esta vez, se desarrolló un trabajo experimental orientado a relacionar entre sí los cementos con adiciones de cenizas volantes y de puzolana natural. Para ello se fabricaron a escala de laboratorio cementos de ambos tipos, empleando como materias primas comunes clinker y yeso y, como variables, diferentes porcentajes de las dos adiciones, que cumplieron previamente los requisitos normalizados en cuanto a sus actividades puzolánicas. La calidad de los cementos fabricados resultó adecuada y concordante con la del cemento portland-puzolánico obtenido a escala industrial con los mismos clinker, yeso y puzolana natural de este estudio. Posteriormente, se determinaron las características de los cementos experimentales y se confeccionaron morteros normales para la realización de ensayos físicos y mecánicos. Los resultados de ensayos indicaron que los cementos con adición de cenizas volantes (CCV requieren menos agua para consistencia normal, presentan tiempos de fraguado mayores y expansiones en autoclave menores que los cementos con adición de puzolana (CP. Los calores de hidratación a 7 y 28 días de edad fueron aproximadamente similares para ambos tipos de cemento. En morteros normales, los cementos CCV mostraron menor retracción de secado, mayor retentividad y mayor fluidez (para igual cantidad de agua que los cementos CP. En los ensayos de exudación se observó que ésta depende más de la finura que el tipo de adición. Finalmente, los ensayos mecánicos señalaron que las resistencias a compresión y flexotracción de los morteros con cementos CCV son menores a edades inferiores que 14 días (del orden de 5 a 10% a un día de edad, pero que a partir de entonces pasan a ser mayores que las de

Febrile neutropenia (FN) is the main treatment-related cause of mortality among children with cancer, as the prolonged use of broad-spectrum antibiotics can lead to antibiotic resistance in these patients. Antibiotic cycling has been reported to limit the emergence of antibiotic-resistant bacteria among adult patients. However, no studies have evaluated pediatric patients with FN. Between September 2011 and February 2014, 126 pediatric cancer patients were admitted to our center for chemotherapy and/or hematopoietic stem cell transplantation and were included in this study. Retrospective and prospective data collection were performed before and after antibiotic cycling, respectively. Between September 2011 and November 2012 (before antibiotic cycling was implemented), intravenous cefpirome was used as the empirical therapy for FN. Between December 2012 and February 2014 (after antibiotic cycling was implemented), the monthly antibiotic cycling involved intravenous piperacillin-tazobactam (PIPC/TAZ), intravenous meropenem or ciprofloxacin (CPFX), and intravenous cefepime in that order. For children aged ≥13 years, the monthly cycling involved intravenous PIPC/TAZ, and CPFX was administered. The detection rates for extended-spectrum β-lactamase producers in blood and stool culture samples decreased significantly after the implementation of antibiotic cycling (0.33/1000 patient-days vs 0/1000 patient-days, p = 0.03; 1.00/1000 patient-days vs 0/1000 patient-days, p Antibiotic cycling was associated with a decreased emergence of multidrug-resistant microbes.

Full Text Available Introdução: a infância é um período de grande importância na formação do ser humano, logo, um episódio de doença pode interromper esse processo, além de interferir na estrutura familiar e gerar ônus ao sistema de saúde. A epidemiologia e a morbidade atuam como importantes instrumentos, pois promovem o conhecimento em saúde e auxiliam na distribuição dos recursos, alcançando os vários níveis administrativos. Porém, estudos que envolvem o perfil de internações pediátricas ainda são escassos. O estudo tem como objetivo delinear perfil epidemiológico e clínico dos pacientes internados na enfermaria de pediatria. Metodologia: estudo realizado na enfermaria de pediatria do Hospital Universitário Walter Cantídio (HUWC com amostra de 119 registros, referentes aos meses de agosto a dezembro de 2015. Resultados: a idade média é de 8,6 anos, sendo que no sexo feminino houve predomínio na faixa da adolescência. Os 3 sistemas mais acometidos foram: sistema digestivo, sistema endócrino e sistema respiratório. A permanência hospitalar média foi de 10,09 dias. Condições crônicas foram encontradas em 48,1% dos registros, sendo o Diabetes Mellitus a mais comum. 25,2% dos casos possuíam internamentos prévios, em sua grande maioria portadores de patologias crônicas. A grande maioria das altas ocorreram para domicílio. Discussão e Conclusão: o estudo demonstra particularidades da enfermaria de pediatria do HUWC, sendo possível guiar o ensino de residentes e estudantes, além de auxiliar na formação de políticas, melhoria do atendimento e preparo da equipe ligada aos cuidados com o paciente.

Full Text Available El objetivo general de este artículo es evaluar los efectos de la inseguridad ciudadana en el uso del espacio público. Dicha evaluación exige analizar dos relaciones que se establecen en el ámbito de la violencia: la relación entre victimización y percepción de inseguridad; y la que se establece entre actitudes sociales y resolución pacífica de conflictos nacionales. Para ello, se analizaron las variables victimización, percepción de inseguridad, uso del espacio físico, actitudes hacia el sistema institucional político y social y hacia la resolución de conflictos nacionales, y las posibles relaciones entre ellas. Los datos para realizar el estudio se obtuvieron por medio de una encuesta que se llevó a cabo con 1 200 personas de 18 y 70 años de edad residentes en la ciudad de Santiago. Los resultados indican que Santiago es una ciudad de habitantes con temor y que el aumento de la percepción de inseguridad de sus habitantes contrasta con el hecho de que las tasas de victimización se hayan mantenido, más o menos, constantes en los años que precedieron a la encuesta. El temor se relaciona con el abandono del espacio público físico y sociopolítico, así como con el refugio en los espacios y la vida privados. La actitud de resolver los conflictos por medios no pacíficos es frecuente y se asocia en mayor medida con la inseguridad, la actitud negativa hacia la democracia y la falta de expectativas sobre el futuro del país. Los resultados de este estudio respaldan la idea de que para superar el temor la gente tiende a adaptarse a la realidad adoptando una postura conformista, homogeneizando las creencias y los comportamientos, y sobreestimando la fuerza como medio para resolver las diferencias.

We sought to develop and externally validate a nomogram and web-based calculator to individually predict the development of serious complications in seemingly stable adult patients with solid tumours and episodes of febrile neutropenia (FN). The data from the FINITE study (n=1133) and University of Salamanca Hospital (USH) FN registry (n=296) were used to develop and validate this tool. The main eligibility criterion was the presence of apparent clinical stability, defined as events without acute organ dysfunction, abnormal vital signs, or major infections. Discriminatory ability was measured as the concordance index and stratification into risk groups. The rate of infection-related complications in the FINITE and USH series was 13.4% and 18.6%, respectively. The nomogram used the following covariates: Eastern Cooperative Group (ECOG) Performance Status ⩾2, chronic obstructive pulmonary disease, chronic cardiovascular disease, mucositis of grade ⩾2 (National Cancer Institute Common Toxicity Criteria), monocytes 0.1). The concordance index was 0.855 and 0.831 in each series. Risk group stratification revealed a significant distinction in the proportion of complications. With a ⩾116-point cutoff, the nomogram yielded the following prognostic indices in the USH registry validation series: 66% sensitivity, 83% specificity, 3.88 positive likelihood ratio, 48% positive predictive value, and 91% negative predictive value. We have developed and externally validated a nomogram and web calculator to predict serious complications that can potentially impact decision-making in patients with seemingly stable FN.

Full Text Available Los aloantígenos de granulocitos se agrupan en 2 grandes categorías: antígenos específicos de granulocitos y antígenos cuya distribución es más amplia y comprende otras líneas celulares. En 1998 se acordó establecer una nueva nomenclatura de los aloantígenos de granulocitos, basada en la localización glucoproteica de estos antígenos. La molécula FcgRIIIb es un miembro de la superfamilia de inmunoglobulinas (CD 16 en la cual se asientan varios de los aloantígenos específicos de granulocitos. Existen otros aloantígenos cuya función y localización se desconocen. Estas moléculas son de gran importancia clínica, pues se ven envueltas en una serie de enfermedades como la neutropenia neonatal aloinmune, cuyo carácter clínico moderado hace que pase inadvertida, la reacción febril no hemolítica, el daño pulmonar agudo relacionado con la transfusión, la neutropenia inmune asociada con el trasplante de médula ósea y la neutropenia autoinmune. Aunque se han producido avances en la caracterización de los aloantígenos de granulocitos, muchos puntos quedan sin aclarar, entre ellos, la significación clínica de muchos antígenos. El desarrollo creciente de técnicas moleculares, bioquímicas y serológicas para el estudio de los antígenos de células sanguíneas, nos permitirá aclarar los puntos que aún permanecen oscuros en este campo de la investigaciónThe granulocyte alloantigens are grouped into 2 big categories: specific granulocyte antigens and antigens, whose distribution is wider and comprises other cellular lines.

Survival and differentiation defects contribute to neutropenia in glucose-6-phosphatase-β (G6PC3) deficiency in a model of mouse neutrophil granulocyte differentiation.

Differentiation of neutrophil granulocytes (neutrophils) occurs through several steps in the bone marrow and requires a coordinate regulation of factors determining survival and lineage-specific development. A number of genes are known whose deficiency disrupts neutrophil generation in humans and in mice. One of the proteins encoded by these genes, glucose-6-phosphatase-β (G6PC3), is involved in glucose metabolism. G6PC3 deficiency causes neutropenia in humans and in mice, linked to enhanced apoptosis and ER stress. We used a model of conditional Hoxb8 expression to test molecular and functional differentiation as well as survival defects in neutrophils from G6PC3(-/-) mice. Progenitor lines were established and differentiated into neutrophils when Hoxb8 was turned off. G6PC3(-/-) progenitor cells underwent substantial apoptosis when differentiation was started. Transgenic expression of Bcl-XL rescued survival; however, Bcl-XL-protected differentiated cells showed reduced proliferation, immaturity and functional deficiency such as altered MAP kinase signaling and reduced cytokine secretion. Impaired glucose utilization was found and was associated with ER stress and apoptosis, associated with the upregulation of Bim and Bax; downregulation of Bim protected against apoptosis during differentiation. ER-stress further caused a profound loss of expression and secretion of the main neutrophil product neutrophil elastase during differentiation. Transplantation of wild-type Hoxb8-progenitor cells into irradiated mice allowed differentiation into neutrophils in the bone marrow in vivo. Transplantation of G6PC3(-/-) cells yielded few mature neutrophils in bone marrow and peripheral blood. Transgenic Bcl-XL permitted differentiation of G6PC3(-/-) cells in vivo. However, functional deficiencies and differentiation abnormalities remained. Differentiation of macrophages from Hoxb8-dependent progenitors was only slightly disturbed. A combination of defects in differentiation

RESUMO: A avaliação do estado nutricional (ingestão alimentar, antropométrica e parâmetros laboratoriais foi realizada em 99 pacientes (67M e 32F de 50 ± 17 anos, internados na Enfermaria de Gastroclínica deste Hospital das Clínicas, nestes últimos 18 meses. Estes pacientes eram portadores de patologias hepatobiliares (39%, gastrintestinais (31%, pancreáticas (10% e outras. Quando comparados com valores de referência, verificou-se, pela associação dos resultados dos indicadores nutricionais, que 61% dos pacientes encontravam-se desnutridos ou com risco nutricional já na internação, sendo este índice de 67% na alta hospitalar. O tempo médio de internação foi de 22 ± 17 dias. Quando os resultados da internação e da alta foram pareados para cada um dos pacientes, verificou-se que cerca de 50% deles apresentaram aumento da ingestão alimentar, dos quais apenas 1/5 mostrou melhora no estado nutricional. A quase totalidade destes pacientes era composta de portadores de diarréia crônica com esteatorréia, recebendo dieta especial. Os pacientes não responsivos à maior ingestão alimentar diminuiu em 22% dos casos, o que pode ser atribuído tanto às dietas restritivas dos cirróticos quanto à falta de apetite na interfase das dietoterapias parenteral ou enteral/oral. Dos indicadores nutricionais o triptofano sérico foi o mais sensível na resposta à ingestão alimentar. Assim, pode-se concluir que a prevalência de desnutrição, entre esses pacientes, é alta, e não diminuiu com a internação, embora, neste período, a ingestão alimentar tenha aumentado. A resposta nutricional à dietoterapia foi positiva sempre que as deficiências dietéticas foram supridas e/ou o hipercatabolismo do paciente compensado. PALAVRAS-CHAVE: Avaliação do estado nutricional; desnutrição hospitalar; gastroenterologia.

Full Text Available Background. The results of the study conducted to determine whether procalcitonin (PCT and interleukin-6 (IL-6 are more sensitive and specific markers of severe infection in children with febrile neutropenia (FN than routinelly used C-reactive protein (CRP are presented in the article. 68 episodes of FN experienced by 32 patients were divided into three groups according to the site of infection. Group 1: episodes of bacteraemia and/or clinical sepsis (n = 16, group 2: episodes of focal infection (n = 16 and group 3: episodes of fever of unknown origin (FUO (n = 36. Blood samples for further PCT and IL-6 determination were collected on three consecutive days. CRP concentrations were measured daily in each patient until the resolution of fever. PCT, IL-6 and CRP concentrations were measured on one occassion in each of the 18 afebrile patients with malignant disase forming the reference group. Serum PCT and IL-6 concentrations were measured by immunochemiluminometric and immunoenzymatic assay. Receiver Operating Characteristic (ROC curves were used to determine optimum sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of the studied parameters.Conclusions. PCT and IL-6 were found to be earlier and more sensitive markers of severe infection in neutropenic patients than CRP. The erliest one was IL-6, followed by PCT and CRP. Sequential determination of PCT up to 72 hours improved its diagnostic value, which was not the case for IL-6.In patients with gramnegative bacteraemias PCT concentracions were 3–5 times higher comparing to grampositive, whereas IL-6 concentrations were comparable in both groups.

Imatinib induced severe skin reactions and neutropenia in a patient with gastrointestinal stromal tumor

Imatinib mesylate has been used for the treatment of unresectable or metastatic gastrointestinal stromal tumors (GIST). The current recommended dose of imatinib is 400 mg/day that is increased to 800 mg/day in cases with disease progression. However, imatinib can be associated with diverse adverse events, which has limited its use. We report a case of severe adverse skin reactions with neutropenic fever during imatinib treatment in a patient with GIST. A 71-year-old man was admitted with a one month history of epigastric pain and a palpable mass in the right upper quadrant. An abdominal CT scan revealed a 20 × 19 cm intraabdominal mass with tumor invasion into the peritoneum. Needle biopsy was performed and the results showed spindle shaped tumor cells that were positive for c-KIT. The patient was diagnosed with unresectable GIST. Imatinib 400 mg/day was started. The patient tolerated the first eight weeks of treatment. However, about three months later, the patient developed a grade 4 febrile neutropenia and a grade 3 exfoliative skin rash. The patient recovered from this serious adverse events after discontinuation of imatinib with supportive care. However, the skin lesions recurred whenever the patient received imatinib over 100 mg/day. Therefore, imatinib 100 mg/day was maintained. Despite the low dose imatinib, follow up CT showed a marked partial response without grade 3 or 4 toxicities. The recommended dose of imatinib for the treatment of GIST is 400 mg/day but patients at risk for adverse drug reaction may benefit from lower doses. Individualized treatment is needed for such patients, and we may also try sunitinib as a alternative drug

Full Text Available Nel 1948 venne Olivetti a Matera. Olivetti venne a Matera con un certo ambasciatore americano che praticamente aveva preparato o stava dando una mano per il piano Marschall, venne a Matera e mi vollero incontrare. Io sono stato chiamato dalla piazza, stavo nella piazza, era il mese di luglio, una cosa di questo genere, e andai in un bar, un bar ad angolo mi ricordo in Via Don Minzioni, dove questo Olivetti mi disse 'ma lei che cosa fa coi sassi?' 'Che cos'è questa storia?' Gli raccontai un po' che cosa facevo io con questi amici, avevamo fatto questo, insomma tutto quello che avevamo fatto nei sassi e che volevamo preparare ancora per presentare a qualcuno un piano di revisionamento dei sassi. Mi ricordo, era la prima volta che avevo visto Adriano Olivetti, ne avevo sentito parlare però non avevo mai visto quest'uomo con gli occhi celesti, minuto, coi capelli bianchi, riccioluto, con una cravatta bianca, cosa che mi fece impressione, una specie di angelo.

2015-03-01

Full Text Available Introducción: la talla baja se ha descrito como característica clínica de niños con retinoblastoma. Esta particularidad puede estar relacionada directamente con la enfermedad de base o con factores externos.  Objetivo: el propósito de esta investigación fue conocer la frecuencia de talla y peso bajos en niños mexicanos con retinoblastoma y correlacionar los valores antropométricos con variables de la enfermedad y ambientales. Materiales y métodos: se analizaron expedientes clínicos de 346 pacientes con retinoblastoma. Se obtuvieron los datos de peso y talla referidos al ingreso; antes del tratamiento. Se comparó el valor de Z con las referencias de la distribución normal de la población mexicana. La asociación de las medidas antropométricas con las variables clínicas, sociales y genéticas se estableció con la prueba de c2. Resultados: la talla y el peso promedio de los niños con retinoblastoma fueron significativamente más bajos que los de la población general (p < 0.001 y p = 0.013, respectivamente. La talla y peso bajos fueron más frecuentes en niños con enfermedad avanzada, provenientes de medio rural y de bajo nivel socioeconómico. Conclusiones: los déficits en peso y talla en niños con retinoblastoma se deben a factores relacionados con enfermedad avanzada al momento del diagnóstico, lo cual a su vez es consecuencia de la situación de marginación de la población rural mexicana. Dado que la mayoría de las variables sociales y ambientales están muy relacionadas y que no podemos descartar posibles factores genéticos, las conclusiones de este estudio deben verificarse analizando las medidas de los padres y hermanos y establecer grupos comparativos para controlar las variables confusas.

Introducción: La individualidad anatómica es clave para reducir el trauma quirúrgico y obtener un mejor resultado. Actualmente, el avance en las neuroimágenes ha permitido objetivar esa individualidad anatómica, permitiendo planificar la intervención quirúrgica. Con este objetivo, presentamos nuestra experiencia con el software Osirix. Descripción de la técnica: Se presentan 3 casos ejemplificadores de 40 realizados. Caso 1: Paciente con meningioma de la convexidad parasagital izquierda en área premotora; Caso 2: Paciente con macroadenoma hipofisario, operada previamente por vía transeptoesfenoidal en otra institución con una resección parcial; Caso 3: Paciente con lesiones en pedúnculo cerebeloso medio bilateral. Se realizó la planificación prequirúrgica con el software OsiriX, fusionando y reconstruyendo en 3D las imágenes de TC e IRM, para analizar relaciones anatómicas, medir distancias, coordenadas y trayectorias, entre otras funciones. Discusión: El software OsiriX de acceso libre y gratuito permite al cirujano, mediante la fusión y reconstrucción en 3D de imágenes, analizar la anatomía individual del paciente y planificar de forma rápida, simple, segura y económica cirugías de alta complejidad. En el Caso 1 se pudo analizar las relaciones del tumor con las estructuras adyacentes para minimizar el abordaje. En el Caso 2 permitió comprender la anatomía post-operatoria previa del paciente, para determinar la trayectoria del abordaje transnasal endoscópico y la necesidad de ampliar su exposición, logrando la resección tumoral completa. En el Caso 3 permitió obtener las coordenadas estereotáxicas y trayectoria de una lesión sin representación tomográfica. Conclusión: En casos de no contar con costosos sistemas de neuronavegación o estereotáxia el software OsiriX es una alternativa a la hora de planificar la cirugía, con el objetivo de disminuir el trauma y la morbilidad operatoria.

Revuelta, Lucerga

2014-01-01

El maltrato no solo se realiza por acción sino también por omisión, la indiferencia hacia la persona con discapacidad es una forma de maltrato muy frecuente. Por ejemplo, ignorar y desatender las necesidades de la persona con discapacidad o, al contrario, la sobreprotección son maneras de maltrato. Cuando a un niño con discapacidad el padre o cuidador le hace todo, el niño se siente agredido pues le están incapacitando más de lo que su enfermedad ya lo hace.

Full Text Available El presente estudio se realizó con el objetivo de estimar el almacén de carbono en sistemas agroforestales (SAF con base en café en la región de Huatusco, zona de mayor producción de café (Coffea arabiga L. en el estado de Veracruz, México, a fin de obtener información cuantitativa sobre el potencial de mitigación de carbono en los SAF de la región. Para ello, se estimaron los reservorios de carbono en biomasa vegetal y la materia orgánica edáfica existentes en sistemas agroforestales de café-plátano, café-macadamia, café-cedro rosado, café-ganado ovino y café-chalahuite, y como referencia de una condición no agroforestal se incluyeron un bosque primario y un potrero con pradera natural. La recolección de muestras se hizo en parcelas de 4 x 25 m (100 m2, donde se colectó biomasa de vegetación herbácea y mantillo, y para el suelo la profundidad de muestreo fue de 0 a 30 cm. El sistema agroforestal que presentó la mayor cantidad de carbono aéreo, estimado con modelos alelométricos, fue café-cedro rosado (Ca + Ce, con 114 Mg C·ha-1, seguido de los sistemas café - macadamia (Ca + Ma, con 34 Mg C·ha-1; café-chalahuite (Ca + Ch, con 29 Mg C·ha-1; café-plátano velillo (Ca + Pl, con 27 Mg C·ha-1; y por último el sistema silvopastoril (Sp, con 2 Mg C·ha-1. Para el caso del carbono orgánico del suelo, el tratamiento (Ca + Ce fue el que presentó mayor contenido de carbono fácilmente oxidable en el suelo, con 58 Mg C·ha-1, y el menor fue el tratamiento potrero (P, con 50 Mg C·ha-1. Del carbono orgánico total entre los SAF el tratamiento Ca + Ce fue el que tuvo el mayor valor, con 172 Mg C·ha-1, y el tratamiento silvopastoril (Sp presentó el menor, con 65 Mg C·ha-1. De los sistemas evaluados se concluye que, en promedio, los SAF almacenan 102 Mg C·ha-1, mientras que el potrero almacena 52 t C·ha-1, y el bosque primario es el sistema que más almacena carbono total, con un valor de 355 Mg C·ha-1.

Full Text Available El carcinoma folicular es un tumor maligno derivado del folículo piloso. La mayor parte de los tumores foliculares son benignos, pero en los últimos años se han publicado casos aislados de tumores anexiales con características de malignidad y con una gran agresividad local siendo en principio tumores que se consideraban benignos. Creemos que este tumor está siendo infradiagnosticado, y como consecuencia, infratratado al ser confundido con otros tumores malignos originados en la piel, como el carcinoma basocelular y sobre todo con el carcinoma epidermoide, en parte por poca documentación y por la dificultad para su diagnóstico anatomopatológico. Presentamos un caso de carcinoma tricofolicular en cuero cabelludo en una mujer de 51 años de edad que rápidamente invade sistema nervioso central y que en solo 3 meses metastatiza a pulmón.

Se comparó la eficacia de 3 métodos de diagnóstico de la PCP en 111 lavados broncoalveolares, pertenecientes a igual número de pacientes con SIDA y diagnóstico presuntivo de PCP, internados en diferentes salas del Hospital Muñiz. Preparaciones en fresco, una modificación rápida de la técnica de Grocott e inmunofluorescencia directa (IFD con anticuerpos monoclonales fueron empleadas para el diagnóstico de PCP sobre preparaciones de los materiales clínicos. Se obtuvieron iguales resultados con las 3 técnicas en 105 (93,6% muestras (15 positivas y 90 negativas; en 3 (2,7% la IFD fue positiva cuando las otras dos fueron negativas y en otras 3 (2,7%, la coloración de Grocott fue negativa cuando las otras dos técnicas resultaron positivas. En los materiales investigados, debido a la abundancia de P. jiroveci, la búsqueda de "estructuras en panal de abejas" en preparaciones al estado fresco se adapta perfectamente como prueba tamiz. La coloración de Grocott permite no sólo el diagnóstico de la PCP sino de otras micosis, y la IFD, por su elevado costo, puede emplearse cuando las otras técnicas son negativas.Since Pneumocystis jiroveci cannot be grown in vitro, laboratory diagnosis of pulmonary pneumocystosis (PCP has been based mainly upon microscopy. The usefulness of 3 diagnostic methods of PCP was compared in 111 bronchoalveolar fluids belonging to an equal number of AIDS patients assisted in different wards of the Muñiz Hospital.

Full Text Available Como humanidad sufrimos la desconexión y separación con la vida toda. Esta ruptura impuesta por el paradigma mecanicista predominante en los últimos cuatrocientos años, nos ha llevado a olvidar la visión holista promovida por las culturas originarias y ancestrales. Esta situación prevalece también en los sistemas educativos dominados por la enseñanza memorística y fragmentada, alejada de la vida, del ser y sentir de las personas aprendientes. Para la superación de la crisis planetaria actual es urgente recuperar la visión holista de la vida y del aprendizaje, para lo cual los procesos docentes universitarios son claves para la formación de personas profesionales comprometidas con la plenitud de la vida sobre la tierra. El sentido de este ensayo es reflexionar sobre la importancia que tiene para la superación de la crisis planetaria actual la recuperación de nuestra conectividad con la vida del planeta tierra en sincronicidad con los aprendizajes, porque los procesos vitales y los procesos de aprendizaje son la misma cosa. Este ensayo está organizado en tres momentos. El primero parte del intercambio de seres, saberes, sentires y experiencias para recuperar nuestra conexión perdida con la vida en nuestro planeta tierra. Un segundo momento donde presentamos reflexiones y conceptualización por medio de la construcción colectiva de conocimientos, con apoyo de personas especialistas en la visión holista y los procesos de interaprendizaje, necesarios para salvar la vida toda. El tercer momento de este ensayo está elaborado con propuestas, claves, signos y señales para la conexión de los procesos vitales en sincronía con los procesos de aprendizaje necesarios en los tiempos actuales.

Full Text Available La proliferación de trabajos biológicos sobre el proceso del VIH/Sida contrasta con el abordaje de la problemática desde la experiencia de los que lo viven. De entre los involucrados, la mujer se vio implicada desde el comienzo como una de las poblaciones de riesgo de contagiar y de enfermarse. La embarazada, objeto privilegiado de la salud pública, contó con programas especiales y normativas estrictas a través de los programas de salud, que dejaron fuera lo que pasaba con ellas en las relaciones con los compañeros y con ellas mismas; sus experiencias, sus perspectivas, sus nociones de futuro; así como su relación con el sistema de salud y con los médicos. En este trabajo se aplicó una metodología cualitativa basada en entrevistas abiertas a mujeres con VIH de la ciudad de Rosario, Argentina. Los hallazgos remiten a una serie de experiencias que relatan sus estrategias y contradicciones, abriendo puentes hacia la comprensión.

Full Text Available Nuestro país no cuenta con la cantidad de sillones de rueda necesario para suplir las necesites de la población con diferentes tipos de discapacidades, en nuestro municipio existen muchos discapacitados que no pueden trasladarse a los servicios de rehabilitación, ni cuenta con medio de traslado en sus propios hogares lo que entorpecen su evolución y los hace mas dependientes; otro grupo de pacientes poseen sillón de ruedas útil para su traslado pero no para realizar  otras  actividades  de  la  vida  diaria  y  tienen  que  valerse  de  otras personas para realizar las mismas. La silla que hemos creado se hace con recursos y materias primas propias de nuestro país sin tener necesidad de compras de accesorios en el exterior; lo que nos permite a la vez que se resuelva un gran problema económico al país.

Procesamiento de argumentos en personas con afasia

Full Text Available En las personas con afasia se alteran diversos procesos lingüísticos. Entre las alteraciones más comunes tenemos aquellas que se producen en el procesamiento sintáctico, lo cual es evidente en el procesamiento de los argumentos. Investigaciones previas realizadas a sujetos con afasia reflejan un procesamientodeficiente de argumentos, lo cual se hace más evidente a medida que el número de argumentos aumenta. Se ha encontrado que mientras mayor es la complejidad en la estructura de la oración, los sujetos afásicos manifiestan mayores dificultades en el procesamiento de la misma. El presente estudio indaga en las dificultades que presentan los sujetos adultos con trastornos afásicos hablantes de español en el procesamiento de argumentos durante tareas de descripción. Este trabajo corrobora la evidencia de que los sujetos con afasia manifiestan un manejo deficiente en el procesamiento de argumentos en las tareas señaladas.

Abstract Background Febrile neutropenia (FN) is a common complication to chemotherapy associated with a high burden of morbidity and mortality. Reliable prediction of individual risk based on pretreatment risk factors allows for stratification of preventive interventions. We aimed to develop such a risk stratification model to predict FN in the 30 days after initiation of chemotherapy. Methods We included consecutive treatment-naïve patients with solid cancers and diffuse large B-cell lymphomas at Copenhagen University Hospital, 2010–2015. Data were obtained from the PERSIMUNE repository of electronic health records. FN was defined as neutrophils ≤0.5 × 10E9/L ​at the time of either a blood culture sample or death. Time from initiation of chemotherapy to FN was analyzed using Fine-Gray models with death as a competing event. Risk factors investigated were: age, sex, body surface area, haemoglobin, albumin, neutrophil-to-lymphocyte ratio, Charlson Comorbidity Index (CCI) and chemotherapy drugs. Parameter estimates were scaled and summed to create the risk score. The scores were grouped into four: low, intermediate, high and very high risk. Results Among 8,585 patients, 467 experienced FN, incidence rate/30 person-days 0.05 (95% CI, 0.05–0.06). Age (1 point if > 65 years), albumin (1 point if 2) and chemotherapy (range -5 to 6 points/drug) predicted FN. Median score at inclusion was 2 points (range –5 to 9). The cumulative incidence and the incidence rates and hazard ratios of FN are shown in Figure 1 and Table 1, respectively. Conclusion We developed a risk score to predict FN the first month after initiation of chemotherapy. The score is easy to use and provides good differentiation of risk groups; the score needs independent validation before routine use. Disclosures All authors: No reported disclosures.

Full Text Available La creciente prevalencia de conductas suicidas en adolescentes se ha convertido en un problema de salud pública. Existen varios factores asociados con este tipo de conductas, tales como: síntomas depresivos y ansiosos, consumo de sustancias nocivas, trastornos de conducta, violencia familiar, negligencia y abuso sexual en la infancia. Otro factor importante que se asocia con la presencia del comportamiento suicida son las autolesiones, las cuales pueden definirse como conductas deliberadas destinadas a producir daño físico sin la intención de provocar la muerte. En adolescentes mexicanos, se ha reportado una frecuencia de autolesiones de 17.1%, con una relación mujer-hombre de 2:1; este problema es tan grave que las clasificaciones diagnósticas psiquiátricas internacionales han propuesto incluir las conductas autolesivas no suicidas como una categoría independiente...

Full Text Available El compromiso del seno frontal con fractura de sus paredes es un tipo de lesión infrecuente, en torno al 5-12% de todas las fracturas faciales. Suele asociarse a lesiones intracraneales, oftalmológicas y a otras fracturas máxilofaciales y cuando conlleva fractura de la pared posterior de seno frontal requiere tratamiento inmediato, siendo necesaria la obliteración del seno frontal debido a la comunicación con meninges y lóbulo frontal, con el riesgo infeccioso que ello representa. Tratamos 18 pacientes con traumatismos craneofaciales y fracturas del seno frontal con compromiso de su pared posterior en el periodo comprendido entre 2007 y 2011; 8 mujeres y 10 varones con edades comprendidas entre los 15 y los 64 años. Todos los casos fueron tratados con reducción y osteosíntesis por vía abierta con distintos abordajes y realizamos en todos colgajos pediculados de vecindad. La vitalidad de los colgajos fue del 100% . Certificamos el posicionamiento correcto mediante tomografía axial computarizada. El tratamiento de las fracturas del seno frontal con compromiso de su pared posterior o del conducto nasofrontal requiere obliteración con tejido vascularizado para evitar comunicaciones con la cavidad nasal.
