    2013-01-01

    Neutropenia is a feature of several primary immunodeficiency diseases (PIDDs). Because of the diverse pathophysiologies of the PIDDs and the rarity of each disorder, data are often lacking, leading to the necessity of empiric treatment. Recent developments in the understanding of neutropenia in several of the PIDDs make a review of the data timely. The category of severe congenital neutropenia continues to expand. Mutations in G6PC3 have been identified as the cause of neutropenia in a minority of previously molecularly undefined cases. Recent advances have broadened our understanding of the pathophysiology and the clinical expression of this disorder. A possible function of the C16orf57 gene has been hypothesized that may explain the clinical overlap between Clerucuzio-type poikiloderma with neutropenia and other marrow diseases. Plerixafor has been shown to be a potentially useful treatment in the warts, hypogammaglobulinemia, infection, and myelokathexis syndrome. Investigations of patients with adenosine deaminase deficient severe combined immunodeficiency have identified neutropenia, and particularly susceptibility to myelotoxins, as a feature of this disorder. Granulocyte-colony stimulating factor is the treatment of choice for neutropenia in PIDD, whereas hematopoietic cell transplantation is the only curative option. The number of PIDDs associated with neutropenia has increased, as has our understanding of the range of phenotypes. Additional data and hypotheses have been generated helping to explain the diversity of presentations of neutropenia in PIDDs.

    PURPOSE OF REVIEW Review normal blood neutrophil concentrations and the clinical approach to neutropenia in the neonatal period. A literature search on neonatal neutropenia was performed using the databases PubMed, EMBASE, and Scopus and the electronic archive of abstracts presented at the annual meetings of the Pediatric Academic Societies. RECENT FINDINGS This review summarizes current knowledge on the causes of neutropenia in premature and critically-ill neonates, focusing on common causes such as maternal hypertension, neonatal sepsis, twin-twin transfusion, alloimmunization, and hemolytic disease. The article provides a rational approach to diagnosis and treatment of neonatal neutropenia, including current evidence on the role of recombinant hematopoietic growth factors. SUMMARY Neutrophil counts should be carefully evaluated in premature and critically-ill neonates. Although neutropenia is usually benign and runs a self-limited course in most neonates, it can be prolonged and constitute a serious deficiency in antimicrobial defense in some infants.

    This case report presents a 44-year-old man with a history of schizophrenia who developed neutropenia on risperidone therapy. The patient's laboratory reports showed a gradual decline of leukocytes and neutrophils after resolution and rechallenging. This was reversed with the discontinuation of risperidone and by switching to olanzapine. In this case report, we also discuss the updated evidence base for management of risperidone-induced neutropenia.

    2011-01-01

    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 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.

    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.

    Full Text Available Amyloidosis represents a heterogeneous group of disorders of protein metabolism and is characterized by deposition of fibrillar proteins in the intra- and extracellular spaces. Here, a case of generalized amyloidosis associated with neutropenia is presented. She had a medical history of multiple bacterial infections. At the age of 14 years, she developed nephrotic syndrome. An increase of antigenic stimulation during the intermittent bouts of acute infections would have been the main factor responsible for the development of secondary amyloidosis in this case. To the best of our knowledge, coexistence between neutropenic disorders and renal amyloidosis in children has not been reported till date. The purpose of this report is to present a case of secondary amyloidosis associated with neutropenia in pediatric age group, probably for the first time.

    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 A Hiperplasia Prostática Benigna (HPB é um crescimento patológico e não maligno da próstata causada principalmente pela proliferação exacerbada das células epiteliais e, principalmente, estromais. Essa neoplasia benigna acomete a maioria dos homens de idade avançada, sendo a condição crônica mais prevalente entre a população masculina. Como mostrado em estudos, o desenvolvimento prostático é intimamente dependente da interação entre as variantes celulares estromais e epiteliais presentes nesta glândula. Entretanto, a cocultura de ambos os tipos celulares é de difícil estabelecimento, uma vez que os dois tipos celulares têm diferentes características de adesão à placa de cultivo celular.

    Neutropenia frequently occurs in patients with Human immunodeficiency virus (HIV) infection. Causes for neutropenia during HIV infection are multifactoral, including the viral toxicity to hematopoietic tissue, the use of myelotoxic agents for treatment, complication with secondary infections and malignancies, as well as the patient’s association with confounding factors which impair myelopoiesis. An increased prevalence and severity of neutropenia is commonly seen in advanced stages of HIV disease. Decline of neutrophil phagocytic defense in combination with the failure of adaptive immunity renders the host highly susceptible to developing fatal secondary infections. Neutropenia and myelosuppression also restrict the use of many antimicrobial agents for treatment of infections caused by HIV and opportunistic pathogens. In recent years, HIV infection has increasingly become a chronic disease because of progress in antiretroviral therapy (ART). Prevention and treatment of severe neutropenia becomes critical for improving the survival of HIV-infected patients. PMID:24654626

    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.

    Variations in the distribution of cardiovascular disease and risk factors by socioeconomic status (SES) have been described in affluent societies, yet a better understanding of these patterns is needed for most low- and middle-income countries. This study sought to describe the relationship between cardiovascular risk factors and SES using monthly family income, educational attainment, and assets index, in 4 Peruvian sites. Baseline data from an age- and sex-stratified random sample of participants, ages ≥35 years, from 4 Peruvian sites (CRONICAS Cohort Study, 2010) were used. The SES indicators considered were monthly family income (n = 3,220), educational attainment (n = 3,598), and assets index (n = 3,601). Behavioral risk factors included current tobacco use, alcohol drinking, physical activity, daily intake of fruits and vegetables, and no control of salt intake. Cardiometabolic risk factors included obesity, elevated waist circumference, hypertension, insulin resistance, diabetes mellitus, low high-density lipoprotein cholesterol, and high triglyceride levels. In the overall population, 41.6% reported a monthly family income education. Important differences were noted between the socioeconomic indicators: for example, higher income and higher scores on an asset index were associated with greater risk of obesity, whereas higher levels of education were associated with lower risk of obesity. In contrast, higher SES according to all 3 indicators was associated with higher levels of triglycerides. The association between SES and cardiometabolic risk factors varies depending on the SES indicator used. These results highlight the need to contextualize risk factors by socioeconomic groups in Latin American settings. Copyright © 2016 World Heart Federation (Geneva). All rights reserved.

    Thirteen cats with Chediak-Higashi syndrome and 22 control cats from the same colony, were evaluated for neutropenia. The absolute neutrophil counts of the Chediak-Higashi syndrome cats were significantly less (P less than 0.05) than those of the control cats. It is concluded that Chediak-Higashi syndrome cats, like Chediak-Higashi syndrome humans, have a neutropenia associated with the other manifestations of the syndrome. Lysozyme activity which was undetectable in the serum of both Chediak-Higashi syndrome and control cats was not of use for determining if the neutropenia was the result of neutrophil destruction.

    El tratamiento de los pacientes con neoplasia y neutropenia febril plantea muchas dudas. Una de ellas, que genera ansiedad en el personal de la salud, el paciente y sus familiares, es la necesidad de hospitalización porque ésta implica exponer a gérmenes intrahospitalarios potencialmente resistentes a un paciente cuyo sistema inmune puede no estar en las mejores condiciones; incluso con un aislamiento óptimo existe el riesgo de adquirir una infección nosocomial. Muchos estudios han tratado de validar métodos para clasificar a los pacientes con fiebre y neutropenia en grupos de diferente riesgo, como fundamento para implementar estrategias de tratamiento selectivo; así se ha abierto la posibilidad de utilizar medidas más conservadoras para el tratamiento de los episodios de bajo riesgo, entre ellas la administración de regímenes orales ambulatorios de antibióticos de amplio espectro; ello sin demeritar la necesidad de aplicar un juicio clínico adecuado, hacer un buen seguimiento y tener acceso a la atención médica inmediata. La neutropenia es una de las consecuencias graves de la quimioterapia para el cáncer, y se ha demostrado que el tratamiento del paciente neutropénico febril con antibióticos intravenosos reduce la mortalidad. La terapia oral podría ser una alternativa aceptable para pacientes bien seleccionados. Ella puede mejorar la calidad de vida de los pacientes con cáncer, evitar las complicaciones asociadas con la terapia intravenosa y disminuir los costos del tratamiento.

    Full Text Available Pain is one of the most common complaints in patients after experiencing a surgery. Surgery is a biphasic event against the human body that implies pain management. In post-surgery patients feel severe pain and 75% of patients have unpleasant experiences due to inadequate pain management.Based on the results of activity reports in Dr. Hi. Abdul Moeloek Public Hospital in Lampung Province in July-December 2016 obtained data operation BPH as many as 51 inhabitants. The objective of this research was to find out the effect of progressive relaxation to an intensity of pain for BPH (Benigna Prostate Hyperplasia post-surgery patient. This was a quasi-experiment research by using one group pretest and posttest design. 20 respondent samples were taken by using accidental sampling. Data were collected by using observation sheet and analyzed by using univariate and bivariate analyses with Wilcoxon sign test. The results showed that the mean value of pain before the progressive relaxation therapy equal to 5.20 with standard deviation 0.834.

    Full Text Available Cancer, chemotherapy, and infections all together make changes in blood rheology and may affect the defense mechanisms by changing the thrombocyte function and endothelial cell. We have examined changes of blood rheology on plasma viscosity to put on probable following criteria for starting the treatment of febrile neutropenia immediately. A total of 27 postchemotherapy patients (16 males and 11 females with febrile neutropenia diagnosed according to international guidelines have been included into the study. The plasma viscosity of the patients whose febrile neutropenia has been successfully treated was also measured to assess the impact of the duration of neutropenia on viscosity. The plasma viscosities of the patients were significantly higher during neutropenic episode than in nonneutropenic state ( except for alkaline phosphatase. All study parameters, particularly acute phase reactants, were statistically similar during both states. In the correlation of analysis with study parameters and stages, significant correlation was not observed between plasma viscosity alteration and leukocyte-neutrophil alteration, also other study parameters. We have demonstrated significantly elevated plasma viscosity in our patients during febrile neutropenic episode. Despite normal values of various parameters known to trigger plasma viscosity, particularly fibrinogen, it can be easily argued that the main mechanism may be the endothelial injury during infectious process and immune response mediated microcirculatory blood flow alterations.

    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.

    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.

    Recurrent or prolonged severe infections associated to panleukopenia strongly suggest primary immune disorders. In recent years, new immunodeficiency syndromes turned up: besides the importance of continuous clinical characterization throughout added reports, the phenotype can easily lead to diagnosis of known rare entities. Our purpose is to review main emerging genetic syndromes featuring lymphopenia combined to neutropenia and/or monocytopenia in order to facilitate diagnosis of rare primary immune deficiencies.

    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.

    Abstract. This paper describes the biology, ecology and nest architecture of Megachile (Moureapis benigna Mitchell in trap nests (NA. The NA were installed in five forest fragments of 2.1 to 920ha, and two disturbed areas (pasture and plantation. We used bamboo canes (NB and black cardboard tubes placed on wooden boards (NC to attract nesting females. Bees occupied 17 NA (12 NB - 9 to 21mm in diameter - and 5 NC - 8 to 10mm in four forest fragments forming 26 nests (one to six nests per NB. No nest was founded in disturbed areas. There was no difference between NB and NC related to the size of formed nests (t= 0.31, p= 0.763, df= 25. The number of cells ranged from 1 to 13 per nest, being larger in NB than in NC (t= 2.26, p= 0.033, df= 25. The construction activity occurred during the rainy season (October to March, with no correlation to climate parameters. Emergence (1 to 12 per nest was correlated with humidity (t= 3.013, p= 0.006. Time to adult emergence varied from 1 to 141 days. The sex ratio was 1.8:1 male/female, differing from 1:1 (Χ2= 9.39, p<0.002. The parasites were Coelioxys otomita Cresson and two other species of Coelioxys. The species demonstrates plasticity in nesting substrate, and preference for cavities with diameters larger than 9mm. There is a possible dependence of the species to forest environments, since the higher occurrence of nesting was in forest areas in advanced stages of regeneration.

    Leukopenia has a high incidence and is usually a reason for additional testing. Benign ethnic neutropenia is a relatively common cause of neutropenia in the negroid population. It can be the cause of aberrant laboratory results in negroid patients. A 55-year-old woman from Ghana was referred to the outpatient clinic because of malaise, leukopenia and neutropenia. Viral infection, haematological malignancy, auto-immune disease and vitamin deficiency were considered, but could not be confirmed by additional testing. Upon further investigation, the neutropenia in this patient was found to have existed for years. Moreover, our patient's son also had asymptomatic leukopenia. Therefore, benign ethnic neutropenia was considered the most likely diagnosis. Serological analysis of the patient's erythrocytes revealed the absence of Duffy (Fy) blood group antigens Fy(a) and Fy(b), which is associated with benign ethnic neutropenia.

    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.

    Neutropenia is a serious toxic complication of chemotherapeutic treatment. For years, mathematical models have been developed to better predict hematological outcomes during chemotherapy in both the traditional pharmaceutical sciences and mathematical biology disciplines. An increasing number of quantitative systems pharmacology (QSP) models that combine systems approaches, physiology, and pharmacokinetics/pharmacodynamics have been successfully developed. Here, I detail the shift towards QSP efforts, emphasizing the importance of incorporating systems-level physiological considerations in pharmacometrics. © 2017 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

    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

    Neutropenic sepsis results as a post-cancer treatment complications and is considered an oncologic emergency. Neutropenic sepsis can result in mortality, especially if it is not identified at an early stage. Septic syndrome is the leading cause of nonrelapse mortality in patients with hematologic malignancies and solid tumors. Therefore, intensive care unit (ICU) nurses must possess a thorough understanding of cancer treatments, hematopoiesis, neutropenia, sepsis, risk factors, and the ability to perform a comprehensive assessment of the oncology patient. Each of these components plays a vital role in the patient's overall management following treatments with chemotherapy, radiation, and stem cell transplantation. The ICU nurse who encompasses this understanding will be able to identify neutropenic sepsis in a timely manner. The early identification of neutropenic sepsis will enable the ICU nurse to expeditiously implement preventive treatment and management to prevent mortality.

    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.

    Full Text Available La hiperplasia prostática benigna, enfermedad común en hombres a partir de los 50 años de edad, consiste en el crecimiento benigno e incontrolado de la glándula prostática y produce diversos síntomas del tracto bajo urinario. Su agente causal multifactorial involucra fundamentalmente el incremento de la conversión de testosterona en dihidrotestosterona por acción de la 5 a-reductasa prostática, lo cual desencadena eventos que propician el incremento en el tamaño de la próstata (componente estático y el aumento del tono del músculo liso de vejiga y próstata (componente dinámico regulado por los adrenoreceptores (ADR-a1. El tratamiento farmacológico de la hiperplasia prostática benigna incluye los inhibidores de la 5a-reductasa, antagonistas de ADR-a1, su terapia combinada y la fitoterapia. El objetivo del presente trabajo fue presentar los aspectos más relevantes de la farmacología de los fármacos utilizados en el tratamiento de la hiperplasia prostática benigna y brindar elementos de su eficacia, seguridad y tolerabilidad.

    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.

    The objective of this study was to identify patterns of fever and neutropenia in pediatric patients undergoing initial hospitalization for hematopoietic stem cell transplantation. A retrospective review of 75 HSCTs over a 4-year period at a single institution was performed, of which 68% were allogeneic and 32% were autologous. Stem cell sources included bone marrow (29%), PBSC (52%) and umbilical cord blood (16%). Fever occurred in 74 (98%) of the episodes. Unexplained fever (FUO) occurred in 43%. Bacteremia without an anatomic focus occurred in 29%, while CVC associated infections occurred in 17%. In 49% of transplants at least one blood culture was positive. The incidence of bacteremia was higher in allogeneic HSCTs (58%) than in autologous transplants (29%). Gram-positive bacteria accounted for 71% of the isolates. Lower rates of bacteremia were observed in patients receiving oral fluoroquinolone prophylaxis. The median duration of fever was 12.5 days and time to engraftment 14 days. Regression analysis demonstrated that duration of fever was strongly associated with time to engraftment, and that time to engraftment was associated with source of cells and number of CD34+ cells/kg administered. Recipients of autologous PBSC had the shortest durations of fever and time to engraftment, while recipients of allogeneic umbilical cord blood had the longest.

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.

    Full Text Available PURPOSE: Intra-arterial chemotherapy is a promising strategy for intra-ocular retinoblastoma. Neutropenia is the most commonly encountered systemic toxicity and in this study we aimed to determine the risk factors associated with the development of severe (≥ grade 3 neutropenia. METHODS: Retrospective review of 187 evaluable cycles of melphalan-containing intra-arterial chemotherapy from the first three cycles administered to 106 patients with intra-ocular retinoblastoma from May 2006 to June 2011. Cycles were considered to be evaluable if (1 blood count results were available in the 7 to 14 days post-treatment interval and (2 concurrent intravenous chemotherapy was not administered. Toxicity was assessed via the Common Terminology Criteria for Adverse Events version 4.0. RESULTS: 54 cycles (29% were associated with grade 3 (n = 43 or grade 4 (n = 11 neutropenia. Multivariate stepwise logistic regression revealed that a higher melphalan dose (>0.40 mg/kg was significantly associated with severe neutropenia during all 3 cycles (odds ratio during cycle one 4.11, 95% confidence interval 1.33-12.73, p = 0.01, but the addition of topotecan and/or carboplatin were not. Prior treatment with systemic chemotherapy was not associated with severe neutropenia risk in any analysis. CONCLUSIONS: Intra-arterial melphalan-based chemotherapy can cause severe neutropenia, especially when a dose of greater than 0.40 mg/kg is administered. Further study with a larger sample may be warranted.

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

    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.

    2013-02-01

    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.

    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.

Embora a colestase intra-hepática recurrente benigna não se associe a dano hepático permanente, os períodos de colestase podem acompanhar-se de considerável morbidade. Relato de um caso de colestase intra-hepática recurrente benigna em adulto do sexo masculino, acompanhado por 7 anos. Durante o período de observação deste caso, três episódios de prurido intenso e icterícia foram documentados, tendo sido excluídas outras etiologias. A duração dos episódios variou de 50 a 90 dias. Como costuma acontecer nesta entidade, as enzimas hepáticas permaneciam normais nos intervalos entre as crises. Apesar de rara, a colestase intra-hepática recurrente benigna deve ser considerada no diagnóstico diferencial das colestases. O esclarecimento do paciente quanto à natureza benigna desta condição é importante para se evitar a iatrogênese.Benign recurrent intrahepatic cholestasis is a rare autosomal recessive disorder characterized by repeated episodes of intense pruritus and jaundice. Patients are completely asymptomatic for months to years between symptomatic periods. We report a case of a patient with a 7-year history of benign recurrent intrahepatic cholestasis. During the follow-up period the patient has suffered three attacks of cholestasis, confirmed by biochemical tests and histological exam. Liver enzimes were normal between the cholestasis episodes. Despite multiple attacks of cholestasis, no permanent liver damage has occurred. Although the diagnosis of benign recurrent intrahepatic cholestasis is rare, it should be included in the evaluation of a patient with cholestasis. The patients should be reassured of the benign course of this disorder.

    Transient neutropenia is reported in some patients on biologic therapy. We report two cases of severe neutropenia in patients with Crohn`s disease following treatment with anti-TNF therapy. In both cases neutrophil specific granulocyte autoantibodies were detected during period of neutropenia and disappeared on cessation of anti-TNF therapy. These may indicate that anti-TNF agents may produce autoimmune agranulocytosis by triggering production granulocyte autoantibodies. The long term management strategy for patients with anti-TNF therapy induced autoimmune neutropenia is uncertain. Copyright © 2012 European Crohn's and Colitis Organisation.

    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.

    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 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.

    Febrile neutropenia is a life-threatening complication of cytotoxic chemotherapy. Empirical antibiotic treatment should be based on predominant pathogens and epidemiological characteristics of the treated community. The aim of the present study was to review cases of febrile neutropenia at the Royal Darwin Hospital (RDH) in order to assess the appropriateness of empirical antibiotic therapy. A retrospective review of cases of febrile neutropenia secondary to malignancy or chemotherapy occurring at the RDH over the period 1994-99. In order to compare infections in this group with those in the wider hospital community, all positive blood cultures in the medical and intensive care units were reviewed for the same time period. Thirty-six episodes of febrile neutropenia were reviewed. Staphylococcus aureus (predominantly methicillin resistant), Pseudomonas aeruginosa and Escherichia coli were the most common organisms identified. Nine patients died of their infection, four with methicillin-resistant S. aureus bacteraemia. S. aureus, E. coli, Streptococcus pneumoniae and Burkholderia pseudomallei (melioid) were the most frequently isolated organisms from blood cultures taken in the medical and intensive care units. Gram-positive organisms are the predominant pathogens in febrile neutropenic episodes at the RDH. Standard empirical therapy with an extended-spectrum penicillin and an aminoglycoside remains appropriate, with the addition of vancomycin when clinical status fails to improve. When practising in the Top End, particular consideration should be given to skin integrity and scabies and testing for Strongyloides in Aboriginal patients.

    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.

    Infection is a serious cause of mortality in febrile neutropenia of pediatric cancer patients. Recently, monotherapy has replaced the combination therapy in empirical treatment of febrile neutropenia. Since there has been no reported trial comparing the efficacy of meropenem and piperacillin-tazobactam (PIP/ TAZ) monotherapies, the present retrospective study was conducted to compare safety and efficacy in febrile neutropenic children with cancer. Charts of febrile, neutropenic children hospitalized at our center between March 2008 and April 2011 for hemato-oncological malignancies were reviewed. Patients received PIP/TAZ 360 mg/kg/day or meropenem 60 mg/kg/day intravenously in three divided doses. Duration of fever and neutropenia, absolute neutrophil count, modification, and success rate were compared between the two groups. Resolution of fever without antibiotic change was defined as success and resolution of fever with antibiotic change or death of a patient was defined as failure. Modification was defined as changing the empirical antimicrobial agent during a febrile episode. Two hundred eighty four febrile neutropenic episodes were documented in 136 patients with a median age of 5 years. In 198 episodes meropenem and in 86 episodes PIP/ TAZ were used. Duration of fever and neutropenia, neutrophil count, sex, and primary disease were not different between two groups. Success rates and modification rate between two groups showed no significant differences (p>0.05). Overall success rate in the meropenem and PIP/TAZ groups were 92.4% and 91.9% respectively. No serious adverse effects occurred in either of the groups. Meropenem and PIP/TAZ monotherapy are equally safe and effective in the initial treatment of febrile neutropenia in children with cancer.

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.

On an average 66,7% patients meet neutropenia during antiviral therapy, and 37,5% and 16,7% among them was the moderate and severe grade accordingly. The major prevalence of leukopenia and neutropenia was evidenced between 12 and 24 weeks of antiviral therapy, the marked severity of neutropenia was noted. It was no correlation between the prevalence of leukopenia and neutropenia and the induction treatment regimens of PegIFNalpha-2a; the tendency for more severity in patients with advanced fibrosis and cirrhosis was detected. It was no infection complications during the therapy observed so it may be provided with full doses of PegIFNalpha-2a in case of mild and moderate grades of leukopenia and neutropenia.

    The management of congenital and acquired neutropenias presents some differences according to the type of the disease. Treatment with recombinant human granulocyte-colony stimulating factor (G-CSF) is not standardized and scanty data are available on the best schedule to apply. The frequency and the type of longitudinal controls in patients affected with neutropenias are not usually discussed in the literature. The Neutropenia Committee of the Marrow Failure Syndrome Group (MFSG) of the Associazione Italiana di Emato-Oncologia Pediatrica (AIEOP) elaborated this document following design and methodology formerly approved by the AIEOP board. The panel of experts reviewed the literature on the topic and participated in a conference producing a document that includes recommendations on neutropenia treatment and timing of follow-up.

    Pediatric patients with hemato-oncological malignancies and neutropenia resulting from chemotherapy have a high risk of acquiring invasive fungal infections. Oral antifungal prophylaxis with azoles, such as fluconazole or itraconazole, is preferentially used in pediatric patients after chemotherapy. During this retrospective analysis, posaconazole was administered based on favorable results from studies in adult patients with neutropenia and after allogeneic hematopoietic stem cell transplantation. Retrospectively, safety, feasibility, and initial data on the efficacy of posaconazole were compared to fluconazole and itraconazole in pediatric and adolescent patients during neutropenia. Ninety-three pediatric patients with hemato-oncological malignancies with a median age of 12 years (range 9 months to 17.7 years) that had prolonged neutropenia (>5 days) after chemotherapy or due to their underlying disease, and who received fluconazole, itraconazole, or posaconazole as antifungal prophylaxis, were analyzed in this retrospective single-center survey. The incidence of invasive fungal infections in pediatric patients was low under each of the azoles. One case of proven aspergillosis occurred in each group. In addition, there were a few cases of possible invasive fungal infection under fluconazole (n = 1) and itraconazole (n = 2). However, no such cases were observed under posaconazole. The rates of potentially clinical drug-related adverse events were higher in the fluconazole (n = 4) and itraconazole (n = 5) groups compared to patients receiving posaconazole (n = 3). Posaconazole, fluconazole, and itraconazole are comparably effective in preventing invasive fungal infections in pediatric patients. Defining dose recommendations in these patients requires larger studies.

    Mother-to-child HIV transmission is currently around 1% in western countries, due to prevention measures. Antiretroviral drugs do have adverse effects, anaemia and myelosupression caused by AZT being the most observed effects. In the present study, we analyse the prevalence of anaemia and neutropenia in an uninfected children cohort born to HIV-infected women. We followed up 623 uninfected children belonging to the FIPSE cohort according to standardised protocols. This cohort groups 8 hospitals from Madrid and follows up HIV infected pregnant women and their children. Anaemia and neutropenia were defined according to the ACTG (AIDS Clinical Trails Group) toxicity tables. Children were classified according to prematurity, ethnic origin, birth weight, withdrawal syndrome, in-utero treatment and neonatal prophylaxis. Categorical variables were compared with the chi2 or the Fisher tests. Anaemia was observed in 188 (30.1%) children during follow-up and 161 (25.8%) had anaemia grade 2 or higher. Prematurity (p triple therapy) did not influence either cytopenia. In our series, the proportion of children with anaemia is high: 30.1% Prematurity, low birth weight and HAART with IP were associated with a higher proportion of anaemia, which was transient and had little clinical relevance. The proportion of children with neutropenia was higher (41.9%) and was associated with prematurity, low birth weight and African origin. The type of neonatal prophylaxis does not seem to influence the development of cytopenias. Persistence of neutropenia (without clinical significance) was observed in a small percentage of the children 12.5%, at 18 months of age.

    The purpose of this study was to determine the incidence and management strategies for post-transplant leukopenia/neutropenia in kidney recipients receiving alemtuzumab induction during the first year following transplantation. We prospectively identified 233 adult patients who underwent kidney transplantation with alemtuzumab induction at a single institution. The incidence and severity of leukopenia (white blood cell count [WBC] ≤2500/mm(3)) and neutropenia (absolute neutrophil count [ANC] ≤500/mm(3)) were evaluated at 1, 3, 6, and 12 months post-transplantation. We determined any association with cytomegalovirus (CMV) infection, graft rejection, and infections requiring hospitalization. We also reviewed interventions performed, including medication adjustments, treatment with granulocyte stimulating factor, and hospitalization. The combined incidence of either leukopenia or neutropenia was 47.5% (n = 114/233) with an average WBC nadir of 1700 ± 50/mm(3) at 131.0 ± 8.5 days and an average ANC nadir of 1500 ± 100/mm(3) at 130.4 ± 9.6 days. No significant difference in graft rejection, CMV infection, or infections requiring hospitalization was found in the leukopenia/neutropenia group vs the normal WBC group (P = .3). The most common intervention performed for leukopenia/neutropenia group was prophylactic medication adjustment. Six patients (5.2%) required a change in >1 medication. The majority of these patients also required granulocyte stimulating factor (61.5%; 32/52), with an average of 2.5 doses given. A total of 25 patients (21.9%) required hospitalization due to leukopenia/neutropenia with an average length of stay of 6 days. Kidney transplant patients receiving alemtuzumab induction required significant interventions due to leukopenia/neutropenia in the first year post-transplantation. These results suggest the need for additional studies aimed at defining the optimum management strategies of leukopenia/neutropenia in this population

    Full Text Available In the novel Misericordia (2004 by Benito Perez Galdós there is a character, Doña Benigna, who has developed an altruistic behavior in favor of other characters. What is certain is that the origin of this cooperative behavior is unclear. We would think that it emanates either from an acquired moral religious education, or from a cultural predisposition or a genetic inheritance. The moral development of the individual is one of the foundations for the birth of man as free individual during this period of Spanish history. Benito Perez Galdós’s narrative raises a debate about the issue of morality as solidarity action in this critical period of Spain’s evolution.

    Full Text Available OBJETIVO: Relatar um caso de neutropenia congênita grave e alertar os pediatras sobre tal diagnóstico em pacientes jovens, com infecções recorrentes. DESCRIÇÃO DO CASO: Lactente jovem com 45 dias de vida, com história de febre alta, letargia, recusa alimentar e hemogramas repetidos com leucopenia importante à custa de polimorfonucleares. A hipótese diagnóstica foi confirmada pelo aspirado de medula óssea, que mostrou hipoplasia de série granulocítica e completa ausência de neutrófilos maduros. Foi introduzida antibioticoterapia de largo espectro e estimulador da formação de colônias de granulócitos. O paciente evoluiu para óbito em decorrência de complicações infecciosas após 21 dias de internação. COMENTÁRIOS: Trata-se de um lactente jovem, portador de uma rara desordem congênita que leva à intensa neutropenia, deixando-o vulnerável a infecções graves e potencialmente fatais. À internação, o paciente apresentava sinais e sintomas sugestivos de sepse, sendo introduzido antibioticoterapia de amplo espectro, necessária por se tratar de lactente jovem, neutropênico e febril. A hipótese diagnóstica se baseou na história clínica e nos leucogramas alterados, sendo posteriormente confirmada pelo aspirado de medula óssea. Foi introduzido o estimulador da formação de colônias de granulócitos, que geralmente é efetivo, porém, nesse caso, não houve sucesso e o paciente evoluiu para óbito devido à grave infecção.OBJECTIVE: To report a case of severe congenital neutropenia and alert pediatricians about its diagnosis in young patients with recurrent infectious diseases.

    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.

  5. ANA-Negative Presentation of SLE in Man with Severe Autoimmune Neutropenia

    Full Text Available Background. Systemic lupus erythematosus (SLE is a chronic, inflammatory, connective tissue disease that commonly affects the joints and a variety of organs due to an overactivation of the body’s immune system. There is wide heterogeneity in presentation of SLE patients, including lung, central nervous system, skin, kidney, and hematologic manifestations. Case Presentation. We report a case of atypical manifestation of SLE in a 53-year-old man who presented with neutropenic fever. Physical findings of interest included oral ulcers on the lower lip, a malar-like rash across the bridge of the nose, and a discoid-like rash on extensor surfaces of the elbows and knees. Labs include ANC <100, weakly positive anti-dsDNA, negative ANA, ferritin 1237 ng/mL, low C3/C4, and positive direct Coombs’ test. A thorough workup for infection and hematologic malignancy was negative. Two days after initiation of therapy with 25 mg IV solumedrol twice a day, the patient’s daily fevers resolved. ANC drastically improved to 2000 after two weeks of steroid treatment. He was later found to have a high titer of anti-neutrophil antibodies. Discussion. Autoimmune leukopenia is a common presentation in SLE, occurring in 50–60% of patients. Severe autoimmune neutropenia is uncommon and may correlate with high anti-neutrophil antibody activity despite a negative ANA. As neutropenia is usually mild, there are currently no guidelines for therapy. For our patient, we started him on low dose IV solumedrol and found that he responded drastically to treatment. Given strongly positive nonspecific anti-neutrophil antibodies in the setting of a negative ANA noted in our patient, it is likely that there are other currently unknown antibodies associated with SLE which may correlate strongly with autoimmune neutropenia.

    We performed a systematic review and meta-analysis to determine the impact of neutropenia or leukopenia experienced during chemotherapy on survival. Eligible studies included prospective or retrospective analyses that evaluated neutropenia or leukopenia as a prognostic factor for overall survival or disease-free survival. Statistical analyses were conducted to calculate a summary hazard ratio and 95% confidence interval (CI) using random-effects or fixed-effects models based on the heterogeneity of the included studies. Thirteen trials were selected for the meta-analysis, with a total of 9,528 patients. The hazard ratio of death was 0.69 (95% CI, 0.64-0.75) for patients with higher-grade neutropenia or leukopenia compared to patients with lower-grade or lack of cytopenia. Our analysis was also stratified by statistical method (any statistical method to decrease lead-time bias; time-varying analysis or landmark analysis), but no differences were observed. Our results indicate that neutropenia or leukopenia experienced during chemotherapy is associated with improved survival in patients with advanced cancer or hematological malignancies undergoing chemotherapy. Future prospective analyses designed to investigate the potential impact of chemotherapy dose adjustment coupled with monitoring of neutropenia or leukopenia on survival are warranted.

    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.

    Immunocompromised children and adolescents receiving treatment for cancer have a considerably increased risk for infection. Neutropenia is the most important single risk factor for infectious complications, and fever in neutropenia is considered as an emergency. Whereas guidelines for the management of fever in neutropenic adults have been established for decades, specific pediatric guidelines have not been developed until recently. As children differ in many aspects from adults such as in the underlying malignancy or in the availability and dosing of antimicrobial compounds, guidelines for pediatric patients are important. This article reviews similarities and differences between the recently published German interdisciplinary guideline of the German Societies of Pediatric Infectious Diseases and Pediatric Oncology and Hematology and a guideline developed by a panel of international experts for the management of fever in neutropenia in children and adolescents. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available En pacientes con cáncer que se presentan con neutropenia febril existe controversia sobre si es mejor utilizar una combinación de antibióticos betalactámicos y aminoglicósidos o si bastaría la monoterapia con betalactámicos de amplio espectro como tratamiento empírico inicial. 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 14 estudios aleatorizados pertinentes a esta pregunta. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que adicionar aminoglicósidos a los betalactámicos en el tratamiento de la neutropenia febril en pacientes con cáncer aumenta la nefrotoxicidad y podría aumentar la mortalidad en comparación con la monoterapia con betalactámicos.

    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.

    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.

    Invasive fungal infections are one of the major complications in pediatric patients during prolonged neutropenia after chemotherapy. Evaluation of the efficacy and safety of the triazole posaconazole in these patients is missing. This multicenter survey analyzed trough concentrations of 33 pediatric patients with a median age of 8 years during 108 neutropenic episodes who received prophylactic posaconazole oral suspension. A total of 172 posaconazole trough levels were determined to median 438 ng/ml (range 111-2011 ng/ml; mean 468 ± 244 ng/ml). Age and gender had no influence on posaconazole plasma levels. Posaconazole was not discontinued due to adverse events in any of the patients. Only hepatic parameters significantly increased beyond the upper normal limit to median values of ALT of 87 U/l (P < .0001), and AST of 67 U/l (P < .0001). One patient with a median posaconazole trough concentration of 306 ng/ml experienced an invasive fungal infection. In conclusion, posaconazole was effective, safe and feasible in 33 pediatric patients with neutropenia ≥5 days after chemotherapy. Median posaconazole plasma concentrations were approximately 1.6-fold lower than the recommended plasma level of 700 ng/ml. Larger patient cohorts are needed to evaluate these findings. © The Author 2016. Published by Oxford University Press on behalf of The International Society for Human and Animal Mycology.

    At the Austin State Hospital, Austin, TX, a number of cases of neutropenia and leukopenia have been observed in children and adolescents who were treated with the combination of valproate and quetiapine. Use of this combination has raised concerns regarding an increased risk of hematologic toxicity. To evaluate the incidence of leukopenia and neutropenia associated with the use of valproate, quetiapine, or the combination in the child and adolescent population. This study was a retrospective evaluation of patients from the child and adolescent psychiatric service of the Austin State Hospital who were treated with valproate, quetiapine, or the combination. Subjects were selected from patients discharged between August 1, 2004, and August 31, 2007. Laboratory data were evaluated to determine the incidence and severity of leukopenia and neutropenia associated with valproate, quetiapine, and a combination of the 2. A total of 131 patients were included in the study. Analysis of the laboratory data revealed a combined incidence of neutropenia and/or leukopenia of 44%, 26%, and 6% in the combination group, valproate monotherapy group, and quetiapine monotherapy group, respectively. Differences in the incidence of neutropenia and/or leukopenia between the quetiapine monotherapy group and valproate monotherapy group, as well as the quetiapine monotherapy group and the combination group reached statistical significance. A significant difference was found among groups based on absolute neutrophil count Common Toxicity Criteria severity (p leukopenia than white (not Hispanic or Latino; 29%) or Hispanic or Latino (11%) patients. Patients treated with valproate or the combination of valproate and quetiapine should be monitored for the occurrence of leukopenia and neutropenia.

    The target trough concentration of vancomycin in patients with febrile neutropenia has not been reported. The aim of this study was to estimate the target trough concentration for febrile neutropenia in patients with hematological malignancy. In this retrospective, single-center, observational cohort study, 63 hospitalized patients with hematological malignancy who were treated with vancomycin for febrile neutropenia due to bacteriologically documented or presumptive Gram-positive infections were analyzed. A significant difference in the first trough concentration of vancomycin was observed between the response and non-response groups, and between the nephrotoxicity and non-nephrotoxicity groups. Multiple logistic regression analyses identified the first trough concentration as the only independent variable associated with clinical efficacy and nephrotoxicity of vancomycin. The areas under the ROC curves were 0.72 and 0.83 for clinical efficacy and nephrotoxicity, respectively. The cut-off values of the first trough concentration were 11.1 μg/ml for clinical efficacy (sensitivity 60%, specificity 87%) and 11.9 μg/ml for nephrotoxicity (sensitivity 77%, specificity 82%). These results suggest a relationship of trough vancomycin concentration with clinical efficacy and incidence of nephrotoxicity. We propose a target trough vancomycin concentration of around 11.5 μg/ml for febrile neutropenia in patients with hematological malignancy. Copyright © 2014 Elsevier B.V. All rights reserved.

    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.

    Rituximab (RTX) is a monoclonal chimeric antibody directed against the CD20 antigen of B lymphocytes. Late onset neutropenia (LON) is a recognised complication of rituximab usually occurring 4 weeks after the last dose and is reported in both haematological and rheumatological conditions. However, it has never been described in a patient with myositis and systemic sclerosis overlap disease. We describe a case of LON in a 54-year-old man who was diagnosed with myositis and then systemic sclerosis overlap disease. It resolved within 7 days, and the patient did not suffer neutropenic sepsis or any other complications. We propose similar mechanisms for LON as described in other conditions and routine blood monitoring in such patients.

    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.

    Fluorouracil, doxorubicin, cyclophosphamide protocol (FAC) is a commonly used regimen for breast cancer due to its proven efficacy, acceptable toxicity, high affordability. While hepatic insufficiency dosing for doxorubicin and fluorouracil have been set, there is paucity of data in the literature on how to reduce doses in renal insufficiency. We sought to determine whether there is an association with pre-chemotherapy creatinine clearance, and the occurrence of clinically significant grade 3 to 5 neutropenia during the course of FAC chemotherapy. A retrospective study involving chart review from 2009 to June 2012, of breast cancer patients given FAC was conducted. Demographic profile, pre-chemotherapy complete blood count and creatinine clearance (CrCl) were recorded. Occurrence of Grade 3 to 5 neutropenia was the endpoint of the study. Descriptive statistics, one tailed t test, logistic regression analysis were done between the outcome and variables. A total of 53 patients were included in the study. The mean age of the patients was 49.77 ± 10.82 years. Patients had an ECOG performance status range of 1 to 3. Patients received mean 5.64 ± 0.92 cycles of FAC protocol chemotherapy. Pre-treatment chemotherapy WBC was 7.41 ± 2.68x109/L, Hemoglobin was 12.60 ± 1.16 g/dL, ANC 4656.89 ± 2379.32. Pre treatment CrCl was 90.79 ± 31.49 ml/min. Thirteen subjects, or 24.53% developed at least grade 3 neutropenia. Patients who developed neutropenia were significantly different from those who did not in terms of baseline WBC p=0.046 and Weight p=0.0119, CrCl p=0.032. Using logistic regression analysis, only creatinine clearance was a significant predictor of neutropenia. There was an inverse association between creatinine clearance and neutropenia, OR 0.887, 95% confidence interval (CI): 0.808- 0.973, p=0.011. The study revealed that breast cancer patients treated with FAC, there was an inverse association between creatinine clearance and occurrence of neutropenia.

    Febrile neutropenia (FN) is an oncologic emergency, and prolonged time to antibiotic administration (TTA) is associated with increased hospital length of stay (LOS) and worse outcomes. We hypothesized that a febrile neutropenia pathway (FNP) quality initiative project would reduce TTA delays for febrile patients with cancer presenting to the emergency department (ED). This prospective study compared ED FNP patients (> 18 years old), between June 2012 and June 2013 with both historical and direct admissions (DA) cohorts at a multispecialty academic center. Interventions included providing patients with FN-Alert cards, standardizing the definition of FN and recognizing it as a distinct chief complaint, revising ED triage level for FN, creating electronic FN order sets, administering empiric antibiotics before neutrophil count result, and relocating FN antibiotics to the ED. The primary outcome was TTA, with a target goal of 90 minutes after ED presentation. In total, 276 FN episodes in 223 FNP patients occurred over the 12-month study period and were compared with 107 episodes in 87 patients and 114 episodes in 101 patients in the historical and DA cohorts, respectively. Use of the FNP reduced TTA from 235 and 169 minutes in historical and DA cohorts, respectively, to 81 minutes, and from 96 to 68 minutes when the order set was not used versus used in the FNP group (P FNP is a significant quality initiative with sustainable interventions, and was able to demonstrate value by decreasing TTA compared to both historical and DA controls in cancer patients presenting to the ED.

    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.

    Prophylactic cotrimoxazole is recommended for infants born to HIV-infected mothers. However, cotrimoxazole may increase the risk of severe anemia or neutropenia. We compared the proportion of HIV-exposed uninfected (HIV-EU) infants experiencing incident severe anemia (and separately, severe neutropenia) between a prospective cohort receiving prophylactic cotrimoxazole from 1 to 6 months vs. infants from two prior trials who did not receive cotrimoxazole. Infants were from rural and urban communities in southern Botswana. A total of 1705 HIV-EU infants were included. Among these 645 (37.8%) were fed with iron-supplemented formula from birth. Severe anemia developed in 87 (5.1%) infants, and severe neutropenia in 164 (9.6%) infants. In an analysis stratified by infant feeding method, there were no significant differences in the risk of severe anemia by prophylactic cotrimoxazole exposure-risk difference, -0.69% (95% confidence interval [CI] -2.1 to 0.76%). Findings were similar in multivariable analysis, adjusted odds ratio (aOR) 0.35 (95% CI 0.07 to 1.65). There were also no significant differences observed for severe neutropenia by cotrimoxazole exposure, risk difference 2.0% (95% CI -1.3 to 5.2%) and aOR 0.80 (95% CI 0.33 to 1.93). Severe anemia and severe neutropenia were infrequent among HIV-exposed uninfected infants receiving cotrimoxazole from 1-6 months of age. Concerns regarding hematologic toxicity should not limit the use of prophylactic cotrimoxazole in HIV-exposed uninfected infants.

    Full Text Available Abstract Introduction The differential diagnosis of neutropenia includes medications, infections, autoimmune diseases, and deficiencies of Vitamin B12 and folate. The association of Vitamin B6 deficiency with severe neutropenia is a rare finding. Case presentation A 51-year-old Caucasian woman presented with fever and profound neutropenia (48 neutrophils/uL. Her clinical history included non-Hodgkin lymphoma, in remission following treatment with allogeneic bone marrow transplantation, quiescent chronic graft-versus-host disease, and squamous cell carcinoma of the skin metastatic to cervical lymph nodes. Medications included atenolol, topical clobetasol, Ditropan (oxybutynin, prophylactic voriconazole, prophylactic valganciclovir, Soriatane (acitretin, and Carac (fluorouracil cream. The bone marrow was hypocellular without metastatic cancer or myelodysplasia. Neutropenia did not respond to stopping medications that have been associated with neutropenia (valganciclovir, voriconazole and Soriatane or treatment with antibiotics or granulocyte colony stimulating factor. Blood tests revealed absence of antineutrophil antibodies, normal folate and B12 levels, moderate zinc deficiency and severe Vitamin B6 deficiency. Replacement therapy with oral Vitamin B6 restored blood vitamin levels to the normal range and corrected the neutropenia. Her cervical adenopathy regressed clinically and became negative on scintography following Vitamin B6 therapy and normalization of the blood neutrophil count. Conclusion Severe pyridoxine deficiency can lead to neutropenia. Screening for Vitamin B6 deficiency, along with folate and Vitamin B12 levels, is recommended in patients with refractory neutropenia, especially those with possible malabsorption syndromes, or a history of chronic-graft-versus host disease. Severe neutropenia may facilitate progression of squamous cell carcinoma.

    In 1931 Lindberg described a limited and benign subcutaneous form of panarteritis nodosa, which, in contrast to systemic panarteritis, only affects the skin. The terms panarteritis nodosa cutanea benigna, cutaneous polyarteritis nodosa, apoplexia cutanea Freund as well as livedo with nodules are used synonymously for this vasculitis which predominantly affects women in the fifth decade of life. Cutaneous lesions characteristically comprise painful subcutaneous nodules or vasculitis racemosa at the lower extremities. The cutaneous panarteritis may be regarded as its own entity or an isolated skin manifestation within systemic panarteritis nodosa. Seven patients (M=3, F=4) presented with subcutaneous, painful nodules (n=2), erythema and edema (n=2) or livedo racemosa (n=3) on the lower extremities. Histological examination revealed perivascular lymphocyte inflammatory infiltrates with fibrinoid necrosis and bulging of endothelial cells. In a direct immunofluorescence examination neither immunoglobulin nor complement deposits could be found. Serological autoimmune parameters, abdominal ultrasound examination, and chest X-rays showed no systemic manifestation. Erythrocyte sedimentation rate was slightly raised, and hepatitis B/C serology was negative. Topical corticosteroids under occlusion (n=3), oral methyl-prednisolone (n=4) in combination with either azathioprine (n=4) or mycophenolate mofetil (n=2) showed no relapses [follow up 28.43 (6-82) months]. The etiology of panarteritis nodosa cutanea is unknown in detail. Both focal infections and hypersensitivity reactions are discussed. Differential diagnosis includes systemic panarteritis, livedo reticularis, Sneddon's syndrome or erythema nodosum. Despite the prognostically favorable but prolonged chronic course of the disease over decades, patients should be regularly examined to exclude possible transition to systemic disease.

    Abstract Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are a critical member of systemic therapy for advanced non-small-cell lung cancer (NSCLC). Erlotinib is the first-generation EGFR-TKIs, the National Comprehensive Cancer Network (NCCN) guidelines recommend it as a first-line agent in patients with sensitizing EGFR mutations. However, the safety of erlotinib plus chemotherapy (CT) or erlotinib alone for advanced NSCLC remains controversial. We carried out a systematic meta-analysis to determine the overall risk of neutropenia and leukopenia associated with erlotinib. PubMed, EMBASE, CBM, CNKI, WanFang database, The Cochrane library, Web of Science, as well as abstracts presented at ASCO conferences and ClinicalTrials.gov were searched to identify relevant studies. RR with 95% CIs for neutropenia and leukopenia were all extracted. The random-effects model was used to calculate pooled RRs and 95% CIs. Power calculation was performed using macro embedded in SAS software after all syntheses were conducted. We identified 12 eligible studies involving 3932 patients. Erlotinib plus CT or alone relative to CT is associated with significantly decreased risks of neutropenia and leukopenia in patients with advanced NSCLC (RR, 0.38; 95% CI, 0.21–0.71; P = 0.00; incidence: 9.9 vs. 35.2%) and (RR, 0.32; 95% CI, 0.11–0.93; P = 0.04; incidence: 3.5 vs. 11.6%), respectively. The subgroup analysis by erlotinb with or without CT showed that erlotinib combine with CT have no significance decrease the relative risks of neutropenia or leukopenia (RR, 0.98; 95% CI, 0.78–1.23; P = 0.87; incidence: 26.2 vs. 30.5%) and (RR, 0.81; 95% CI, 0.34–1.95; P = 0.64; incidence: 6.5 vs. 9.3%), respectively. However, erlotinib alone could decrease incidence of neutropenia (RR, 0.14; 95% CI, 0.07–0.27; P = 0.00; incidence: 3.7 vs. 40.8%) or leukopenia (RR, 0.07; 95% CI, 0.01–0.45; P = 0.01; incidence: 0.8 vs. 15.7%).

    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.

    Chronic idiopathic neutropenia (CIN) is a granulocytic disorder associated with presence of activated, myelosuppressive T-lymphocytes. In the present study we have evaluated constituents of humoral immunity in CIN patients (n=48) compared to healthy controls (n=52). CIN patients displayed lower serum IgG levels due to a reduction in IgG1, IgG3, IgG4 but not IgG2, lower IgA and increased IgM levels compared to controls. The proportion of CD19 + cells did not differ between patients and controls; however the proportion of the naïve IgD + /CD27 - B-cells was increased and the proportion of class-switched memory IgD - /CD27 + B-cells was decreased in the patients. The percentage of CD40 + B-cells did not differ between patients and controls and no aberrations in the CD40-meadiated signal transduction pathway or in CD40-gene polymorphisms were identified. These data provide further evidence that immune disturbances are associated with the pathophysiology of CIN and point out for the first time the implication of the B-cell system.

    The risks of severe leukopenia and agranulocytosis have varied over time and among geographical regions and cultures, with little information available on South American populations. Accordingly, we reviewed and analyzed data from a 6-year experience monitored by an Argentine national registry to which reporting of adverse events reports is required. We analyzed data for 2007-2012 from the pharmacovigilance program of the Argentine drug-regulatory agency (ANMAT) using standard bivariate and multivariate statistical methods and survival analysis. We identified 378 cases of adverse hematological events over 6 years among an average of 12 305 individuals/year treated with clozapine (308±133 mg/day) to estimate the mean annualized rates of leukopenia [0.19 (95% confidence interval [CI] 0.11-0.27)], neutropenia [0.38 (95% CI 0.34-0.43)], and agranulocytosis [0.05 (95% CI 0.02-0.08)] % per year [median latency 2 (95% CI 1.3-2.1) months]; fatalities related to agranulocytosis averaged 4.2 (95% CI 0.0-9.2) per 100 000 treated individuals/year. Factors associated significantly and independently with agranulocytosis were female sex, older age, and use of other drugs in addition to clozapine. With monitoring by international standards, recent risks of clozapine-associated agranulocytosis in Argentina were lower, but fatality rates were higher than that in other regions of the world. Risk factors include the use of multiple psychotropic drugs, female sex, and older age.

  20. Neutropenia exacerbates infection by Acinetobacter baumannii clinical isolates in a murine wound model

    2015-10-01

    Full Text Available The Gram negative coccobacillus Acinetobacter baumannii has become an increasingly prevalent cause of hospital-acquired infections in recent years. The majority of clinical A. baumannii isolates display high-level resistance to antimicrobials, which severely compromises our capacity to care for patients with A. baumannii disease. Neutrophils are of major importance in the host defense against microbial infections. However, the contribution of these cells of innate immunity in host resistance to cutaneous A. baumannii infection has not been directly investigated. Hence, we hypothesized that depletion of neutrophils increases severity of bacterial disease in an experimental A. baumannii murine wound model. In this study, the anti-Ly-6G monoclonal antibody (mAb, 1A8, was used to generate neutropenic mice and the pathogenesis of several A. baumannii clinical isolates on wounded cutaneous tissue was investigated. We demonstrated that neutrophil depletion enhances bacterial burden using colony forming unit determinations. Also, mAb 1A8 reduces global measurements of wound healing in A. baumannii-infected animals. Interestingly, histological analysis of cutaneous tissue excised from A. baumannii-infected animals treated with mAb 1A8 displays enhanced collagen deposition. Furthermore, neutropenia and A. baumannii infection alter pro-inflammatory cytokine release leading to severe microbial disease. Our findings provide a better understanding of the impact of these innate immune cells in controlling A. baumannii skin infections.

    Because adenine is effective for managing cases of radiation-induced and drug-induced leukopenia, it may be effective in cases of antipsychotic-induced leukopenia and neutropenia. Here, we report our experience with patients with leukopenia and neutropenia caused by an antipsychotic overdose or discontinuation of lithium carbonate, in whom adenine administration ameliorated the white blood cell and neutrophil counts. The progress of patients suggests that adenine is effective in cases of leuk...

    Alloimmune neonatal neutropenia (ANN) is a rare but potentially life-threatening disorder of neonates. Demonstration of alloantibodies against granulocyte-specific antigens shared by neonatal and paternal granulocytes in the maternal serum is essential in the diagnosis of ANN. In contrast to granulocyte-specific alloantibodies, the significance of human leucocyte antigen (HLA) class I antibodies for ANN is still a matter of debate. We report on a case of severe isolated and prolonged neutropenia due to anti-HLA B49 alloimmunization only. Immediately after birth, severe, isolated neutropenia was observed and lasted for up to 2 months. Results of serologic testing showed only anti-HLA B49 antibodies in the maternal and neonate's sera. HLA typing showed HLA class I (B49) incompatibility between the mother and the child. Granulocyte-specific antibodies were not detected. Adsorption of the maternal serum with HLA B49-bearing platelets removed serum reactivity with paternal neutrophils. Our results support the idea that certain HLA class I antibodies can induce ANN.

    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. Systemic Amphotericin was used in 4 patients, 2 responded. Infection related mortality rate was 4%. (author)

    Full Text Available Benign rolandic epilepsy (BRE is known for its dissociation from structural alterations. Nevertheless, the number of cases with reported organic lesions has been increasing. This led to the creation of two subgroups, "benign" and "non benign" BRE, and resulted in the need for additional parameters to define electrographic benignity. We assessed the possible associations between interictal electroencephalographic findings and clinical behavior in 60 BRE cases, testing four parameters of electrographic benignity (paroxysm morphology, horizontal dipole, base rhythms, laterality of rolandic spikes. We also assessed the relationship between neuroimaging findings and electrographic and clinical classifications, and found a statistically significant association (sensitivity=73.5%; specificity=81.8%; positive predictive value=94.8%; negative predictive value=40.9%. Three of the electrographic parameters proposed were associated with clinical classification: paroxysm morphology, horizontal dipole, and base rhythms. Cases electrographically classified as benign have 21 times more chances to be equally classified as clinically benign according with the tested criteria.A epilepsia rolândica benigna da infância (ERBI é conhecida por não estar associada a alterações estruturais. Contudo, tem aumentado o número de casos com lesões orgânicas. Tal fato levou à criação de dois subgrupos, "benigno" e "não benigno", e criou a necessidade de definir parâmetros adicionais de benignidade eletrográfica. Nós avaliamos as possíveis associações entre achados do EEG interictal e comportamento clínico em 60 casos de ERBI, testando quatro parâmetros de benignidade eletrográfica (morfologia do paroxismo, dipolo horizontal, ritmos de base e lateralidade das pontas rolândicas. Também foi avaliada a associação entre os achados de neuroimagem e as classificações eletrográfica e clínica; encontrou-se uma associação estatisticamente significativa

    Filgrastim-sndz, a granulocyte-colony stimulating factor (G-CSF), was introduced as a biosimilar to filgrastim in 2015, but real-world comparative effectiveness for filgrastim versus filgrastim-sndz has not been reported to date. To (a) compare the incidence of febrile neutropenia for patients taking filgrastim versus those taking filgrastim-sndz and (b) compare the incidence of a potential serious adverse event for filgrastim versus filgrastim-sndz. This retrospective cohort study identified patients receiving a G-CSF following chemotherapy, using administrative claims from the Humana Research Database. Patients enrolled in a Medicare Advantage Prescription Drug plan with a claim for a G-CSF from October 1, 2015, through September 30, 2016, were identified. G-CSF use had to occur within 6 days of exposure to chemotherapy and without any subsequent chemotherapy within 14 days after G-CSF use. Febrile neutropenia requiring hospitalization was defined as hospitalization within 14 days after G-CSF use with (a) diagnosis of infection and/or neutropenia (broad definition) or (b) infection and neutropenia diagnoses (narrow definition). Serious adverse drug events (spleen rupture, acute respiratory syndrome, serious allergic reactions, capillary leak syndrome, thrombocytopenia, leukocytosis, cutaneous vasculitis, or bones and muscle ache) were also identified within 14 days after G-CSF use. An incidence difference of < 1% with 90% CI crossing zero qualified as support for noninferiority. Two-tailed chi-square tests were also used to investigate differences. A total of 88 filgrastim and 101 filgrastim-sndz patients were identified. Filgrastim and filgrastim-sndz met the criteria for noninferiority based on an incidence difference of -0.6% (90% CI = -5.1%-4.0%; P = 0.84) for the broad definition of febrile neutropenia and a difference of -0.8% (90% CI = -3.8%-2.1%; P = 0.64) for the narrow definition. For the analysis of serious adverse events, an incidence difference of -2

    Invasive fungal infections (IFI) cause prolonged hospitalizations and increase the possibility of death among patients with cancer and febrile neutropenia (FN). Up to 10% of febrile neutropenic episodes may be caused by IFI. To estimate the incidence of IFI among a large group of Chilean children with cancer and FN. Clinical and laboratory information was collected from a data base provided by the "Programa Infantil Nacional de Drogas Antineoplásicas" (PINDA) that included 445 FN episodes occurring in five hospitals in Santiago, Chile. This information was used to identify children that presented with signs and symptoms compatible with an IFI. According to predefined criteria based on a literature review, IFI episodes were categorized as "proven", "probable" or "possible". A total of 41/445 episodes (9.2%) were compatible with an IFI of which 4 (0.9%) were proven, 23 (5.2%) probable, and 14 (3.1%) possible. Hospitalization was longer (27 vs 8 days, p < .01), new infectious foci appeared with higher frequency (71 vs 38%, p < .01), and mortality was higher (10 vs 1.6%, p < .001) in children with IFI compatible episodes, when compared to children who did not have an IFI. The estimated incidence of IFI in Chilean children with cancer and FN ranged between 6-9% depending on the stringency of criteria selection used for classification. This estimate is similar to that reported by other studies. The low detection yield of clinically compatible IFI underscores the need of improved diagnosis of fungal infections in this population.

    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.

    Guidelines advise primary granulocyte colony-stimulating factor (G-CSF) prophylaxis during chemotherapy if risk of febrile neutropenia (FN) is more than 20%, but this comes with considerable costs. We investigated the incremental costs and effects between two treatment strategies of primary pegfilgrastim prophylaxis. Our economic evaluation used a health care perspective and was based on a randomized study in patients with breast cancer with increased risk of FN, comparing primary G-CSF prophylaxis throughout all chemotherapy cycles (G-CSF 1-6 cycles) with prophylaxis during the first two cycles only (G-CSF 1-2 cycles). Primary outcome was cost effectiveness expressed as costs per patient with episodes of FN prevented. The incidence of FN increased from 10% in the G-CSF 1 to 6 cycles study arm (eight of 84 patients) to 36% in the G-CSF 1 to 2 cycles study arm (30 of 83 patients), whereas the mean total costs decreased from € 20,658 (95% CI, € 20,049 to € 21,247) to € 17,168 (95% CI € 16,239 to € 18,029) per patient, respectively. Chemotherapy and G-CSF determined 80% of the total costs. As expected, FN-related costs were higher in the G-CSF 1 to 2 cycles arm. The incremental cost effectiveness ratio for the G-CSF 1 to 6 cycles arm compared with the G-CSF 1 to 2 cycles arm was € 13,112 per patient with episodes of FN prevented. We conclude that G-CSF prophylaxis throughout all chemotherapy cycles is more effective, but more costly, compared with prophylaxis limited to the first two cycles. Whether G-CSF prophylaxis throughout all chemotherapy cycles is considered cost effective depends on the willingness to pay per patient with episodes of FN prevented.

    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.La neutropenia y las infecciones constituyen los eventos adversos más limitantes en la aplicación de quimioterapia.

    The choice of chemotherapy regimens is often constrained by the patient's tolerance to the side effects of chemotherapeutic agents. This dose-limiting issue is a major concern in dose regimen design, which is typically focused on maximising drug benefits. Chemotherapy-induced neutropenia is one of the most prevalent toxic effects patients experience and frequently threatens the efficient use of chemotherapy. In response, granulocyte colony-stimulating factor (G-CSF) is co-administered during chemotherapy to stimulate neutrophil production, increase neutrophil counts, and hopefully avoid neutropenia. Its clinical use is, however, largely dictated by trial and error processes. Based on up-to-date knowledge and rational considerations, we develop a physiologically realistic model to mathematically characterise the neutrophil production in the bone marrow which we then integrate with pharmacokinetic and pharmacodynamic (PKPD) models of a chemotherapeutic agent and an exogenous form of G-CSF (recombinant human G-CSF, or rhG-CSF). In this work, model parameters represent the average values for a general patient and are extracted from the literature or estimated from available data. The dose effect predicted by the model is confirmed through previously published data. Using our model, we were able to determine clinically relevant dosing regimens that advantageously reduce the number of rhG-CSF administrations compared to original studies while significantly improving the neutropenia status. More particularly, we determine that it could be beneficial to delay the first administration of rhG-CSF to day seven post-chemotherapy and reduce the number of administrations from ten to three or four for a patient undergoing 14-day periodic chemotherapy.

    The effects of diabetes mellitus on the differential white blood cell count are not widely studied in the Arab populations. The objective of this cross-sectional, retrospective study is to assess the influence of chronic diabetes mellitus on white blood cell counts, absolute neutrophil (ANC) and lymphocyte counts (ALC) as well as the prevalence of benign ethnic neutropenia among Arabs attending the Dasman Diabetes Institute (DDI) in Kuwait. 1,580 out of 5,200 patients registered in the DDI database qualified for our study. Age, gender, HbA1c and creatinine levels, estimated glomerular filtration rate as well as average WBC, ANC and ALC levels, presence of diabetes-associated complications and anti-diabetic medications were analyzed. Our results showed the mean value of the WBC was 7.6 ± 1.93 x 109/L (95% CI: 2.95-17.15). The mean ANC was 4.3 x 109/L (95% CI: 0.97-10.40) and mean ALC was 2.5 x 109/L (95% CI: 0.29-10.80). Neutropenia (ANC: patients (0.94%). Six patients (0.4%) fulfilled the definition of lymphopenia (ALC Patients with an HbA1c ≥ 7% and those taking at least 3 anti-diabetic medications showed higher values for ANC and ALC. Patients with diabetes-associated neuropathy or nephropathy displayed higher mean ANC values. Our study was limited by overrepresentation of patients over 50 years old compared to those under 50 as well as selection bias given its retrospective nature. Our study showed that patients with poorly controlled diabetes displayed higher ANC and ALC levels. In addition, patients with DM-associated complications showed higher ANC levels. This finding would suggest that DM exerts a pro-inflammatory influence on differential WBC counts. Our study also showed that the prevalence of benign ethnic neutropenia was lower than previously reported in other studies.

    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.

    Dermatologists at the University of California, San Francisco recently reported two patients in the online Journal of the American Academy of Dermatology with purpura presumably induced by levamisole in contaminated cocaine. Levamisole-induced vasculitis and neutropenia has been reported elsewhere in the United States and Canada. Up to 70% of cocaine in the United States could be contaminated. We sought to describe similar cases of vasculitis associated with cocaine use. This is a retrospective case series. We report 6 remarkably similar patients seen over just the past few months with retiform purpura on the body and tender purpuric eruptions, necrosis, and eschars of the ears after cocaine use in New York and California. All of these patients had positive perinuclear antineutrophil cytoplasmic antibody values and 3 of the 6 also had an associated neutropenia. Direct immunofluorescence studies suggested an immune complex-mediated vasculitis. This case series is descriptive in nature and, because testing is not easily performed, we did not test for levamisole in the serum or blood to prove this is the causative agent. It appears the use of cocaine is associated with the peculiar clinical findings of ear purpura, retiform purpura of the trunk, and neutropenia. We believe this case series may represent the tip of the iceberg as a looming public health problem caused by levamisole. Although the direct causal relationship may be difficult to establish, the astute dermatologist or primary care physician should be able to recognize the characteristic skin lesions and should be wary of the potential development of agranulocytosis.

    Considerable variation in the management of fever and neutropenia (FN) exists, with factors associated with treatment variation not well described. An online survey of 90 pediatric cancer providers in Michigan was performed in Spring 2014. The survey frame was pediatric patients with cancer receiving treatment, with a Port-a-cath, who were clinically stable. Criteria for "Decreased" and "Increased" risk groups were defined by respondents. Survey questions addressed FN definitions, risk groups conceptualization, routine clinical practice, and management guidelines, in the context of risk groups and distance to treating institution. Fifty providers responded (56%); the majority defined a febrile event as temperature >38.3°C and/or 2 events >38.0°C within a 24-hour period. Neutropenia was defined as current or anticipated absolute neutrophil count (ANC) 2 hours away. Respondents were significantly more likely to have a "Decreased Risk" patient travel over 2 hours if they rated the local ED as "Poor to Fair" on ability to access Port-a-caths (P = .048). Most respondents would discharge patients who are afebrile for 24 hours, blood cultures negative for 48 hours, and neutrophil count of greater than 200/μL; 40% preferred discharge on oral antibiotics when the ANC pediatric patients with cancer is significantly influenced by the providers' perceptions of local EDs. Future investigation of local hospitals' ability to provide urgent evaluation, combined with parental perspectives, could lead to improvements in timely and effective management.

    Full Text Available Neutropenia secondary to chemotherapy in breast cancer patients can be life-threatening and there are no biomarkers available to predict the risk of drug-induced neutropenia in those patients. We previously performed a genome-wide association study (GWAS for neutropenia events in women with breast cancer who were treated with 5-fluorouracil, epirubicin and cyclophosphamide and recruited to the SUCCESS-A trial. A genome-wide significant single-nucleotide polymorphism (SNP signal in the tumor necrosis factor superfamily member 13B (TNFSF13B gene, encoding the cytokine B-cell activating factor (BAFF, was identified in that GWAS. Taking advantage of these existing GWAS data, in the present study we utilized a pathway-based analysis approach by leveraging knowledge of the pharmacokinetics and pharmacodynamics of drugs and breast cancer pathophysiology to identify additional SNPs/genes associated with the underlying etiology of chemotherapy-induced neutropenia. We identified three SNPs in the hyaluronan mediated motility receptor (HMMR gene that were significantly associated with neutropenia (p < 1.0E-04. Those three SNPs were trans-expression quantitative trait loci for the expression of TNFSF13B (p < 1.0E-04. The minor allele of these HMMR SNPs was associated with a decreased TNFSF13B mRNA level. Additional functional studies performed with lymphoblastoid cell lines (LCLs demonstrated that LCLs possessing the minor allele for the HMMR SNPs were more sensitive to drug treatment. Knock-down of TNFSF13B in LCLs and HL-60 promyelocytic cells and treatment of those cells with BAFF modulated the cell sensitivity to chemotherapy treatment. These results demonstrate that HMMR SNP-dependent cytotoxicity of these chemotherapeutic agents might be related to TNFSF13B expression level. In summary, utilizing a pathway-based approach for the analysis of GWAS data, we identified additional SNPs in the HMMR gene that were associated with neutropenia and also were

    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

    Fever in neutropenia (FN) is the most frequent potentially life threatening complication of chemotherapy for cancer. Prediction of the risk to develop FN during chemotherapy would allow for targeted prophylaxis. This retrospective, single centre cohort study in pediatric patients diagnosed with cancer before 17 years covered two decades, 1993 to 2012. The 583 (73%) of 800 patients diagnosed with cancer who had received chemotherapy were studied here. Data on 2113 observation periods was collected, defined by stable combinations of 11 predefined characteristics potentially associated with FN. They covered 692 years of cumulative chemotherapy exposure time, during which 712 FN episodes were diagnosed, 154 (22%) of them with bacteremia. The risk to develop FN and FN with bacteremia remained stable over time. These data can mainly be used to study FN risks over time and between centers, and to derive or externally validate FN risk prediction rules.

[{sup 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/{mu}l 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/{mu}l (range 0-730 cells/{mu}l). 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.)

    To systematically review the available evidence to evaluate (1) the prevalence and degree of leukopenia, lymphopenia, and neutropenia in patients with systemic lupus erythematosus (SLE), (2) whether these conditions carry a major infection risk for patients, and (3) whether a treatment with colony stimulating factors (CSF) can be an effective and safe option in SLE patients with leukopenia. MedLine and Embase were searched by including MeSH terms, text words, and subheadings "systemic lupus erythematosus," "leukopenia" (first search), and "colony stimulating factor" (second search). Inclusion and exclusion criteria were a priori defined and two reviewers screened the retrieved articles for selection criteria; data from the included studies were recorded in ad hoc standard forms; the results were synthesized and transported to evidence tables. A total of 17 articles were included in the systematic literature review: nine articles were retrieved for the first research question and 11 for the second while no articles satisfied the inclusion criteria for the third research question. The prevalence of leukopenia is reported in 22-41.8% of cases and lymphopenia is reported cumulatively from 15% to 82% of the patients while neutropenia is described in 20-40% of the patients. There is no evidence of a significant association between overall reduction of white blood cells and infection occurrence while some studies found a strong association between low lymphocytes/neutrophils count and the risk of major infections. Only case reports and case series have been found to investigate the safety of CSF in SLE patients. The results of this systematic literature review are inconclusive for many aspects related to the original research questions and highlight the need for further studies. Indeed, the strength of the evidence is not sufficiently robust to draw specific recommendations on how to balance between the need to treat the patient with SLE with immunosuppressive drugs and

    Prospective data on the use of granulocyte-colony-stimulating factor (G-CSF) in non-Hodgkin's lymphoma and its aggressive subtypes, including diffuse large B-cell lymphoma (DLBCL), are limited. MONITOR-GCSF is a pan-European, multicenter, prospective, observational study aiming to describe treatment patterns and clinical outcomes in patients receiving biosimilar filgrastim in the prophylaxis of chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN). This analysis describes patient characteristics, treatment patterns, and outcomes for 245 patients with stage 3 or 4 DLBCL receiving ≤6 chemotherapy cycles as part of MONITOR-GCSF study, including patients aged ≥65 years and ≥70 years. Outcomes of interest included the incidence of CIN and FN, antibiotic prophylaxis, biosimilar filgrastim prophylaxis, and adverse events (AEs). MONITOR-GCSF included 245 patients with DLBCL. Of these patients, 87 (35.5%) experienced one or more CIN (any grade) episode and 24 (9.8%) experienced FN (any grade). The most frequent AE reported was bone pain (n = 7, 2.9%), followed by arthralgia (n = 2, 0.8%) and back pain (n = 2, 0.8%). In real-life practice, biosimilar filgrastim demonstrated clinical effectiveness and safety in patients with DLBCL. The large percentage of patients aged ≥65 years adds to the evidence on how to best treat older patients with DLBCL receiving myelosuppressive chemotherapy. © 2017 The Authors.

    Benign prostatic hyperplasia is very common in the general population, both from the histological and the clinical points of view. The role of different factors in its development has been defined by means of epidemiological studies. One such factor is the composition of the diet, as the regular consumption of certain foods may either protect against benign prostatic hyperplasia or increase the risk of its development. Among foods which may play a protective role are lycopene, phytoestrogens and vegetables. On the other hand, the risk of developing the disease may be increased by a diet rich in fat and calories. In this article the main clinical trials concerning this relationship are reviewed, as a way of informing physicians on the dietetic patterns that may influence the frequency or the symptoms of this disease.

    La hiperplasia prostática benigna es muy común en la población general, tanto desde el punto de vista histológico como del clínico. El papel en ella de diversos factores se ha definido por medio de estudios epidemiológicos.

    Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are a critical member of systemic therapy for advanced non-small-cell lung cancer (NSCLC). Erlotinib is the first-generation EGFR-TKIs, the National Comprehensive Cancer Network (NCCN) guidelines recommend it as a first-line agent in patients with sensitizing EGFR mutations. However, the safety of erlotinib plus chemotherapy (CT) or erlotinib alone for advanced NSCLC remains controversial. We carried out a systematic meta-analysis to determine the overall risk of neutropenia and leukopenia associated with erlotinib. PubMed, EMBASE, CBM, CNKI, WanFang database, The Cochrane library, Web of Science, as well as abstracts presented at ASCO conferences and ClinicalTrials.gov were searched to identify relevant studies. RR with 95% CIs for neutropenia and leukopenia were all extracted. The random-effects model was used to calculate pooled RRs and 95% CIs. Power calculation was performed using macro embedded in SAS software after all syntheses were conducted. We identified 12 eligible studies involving 3932 patients. Erlotinib plus CT or alone relative to CT is associated with significantly decreased risks of neutropenia and leukopenia in patients with advanced NSCLC (RR, 0.38; 95% CI, 0.21-0.71; P = 0.00; incidence: 9.9 vs. 35.2%) and (RR, 0.32; 95% CI, 0.11-0.93; P = 0.04; incidence: 3.5 vs. 11.6%), respectively. The subgroup analysis by erlotinib with or without CT showed that erlotinib combine with CT have no significance decrease the relative risks of neutropenia or leukopenia (RR, 0.98; 95% CI, 0.78-1.23; P = 0.87; incidence: 26.2 vs. 30.5%) and (RR, 0.81; 95% CI, 0.34-1.95; P = 0.64; incidence: 6.5 vs. 9.3%), respectively. However, erlotinib alone could decrease incidence of neutropenia (RR, 0.14; 95% CI, 0.07-0.27; P = 0.00; incidence: 3.7 vs. 40.8%) or leukopenia (RR, 0.07; 95% CI, 0.01-0.45; P = 0.01; incidence: 0.8 vs. 15.7%). The power analysis suggests that a power of 61.31% was determined

    D-index which combines the intensity and duration of neutropenia is reported as a tool for evaluating the dynamics of neutropenia. This study aimed to analyze the relationship between D-index and oral complications (i.e., oral mucositis [OM] and odontogenic infection [OI]) during chemotherapies for hematological malignancies. A total of 421 chemotherapeutic courses in 104 patients were analyzed. Chemotherapeutic courses in patients who finished all of the prophylactic dental treatments were defined as "treatment Finish". Chemotherapeutic courses in patients who did not finish prophylactic dental treatments were defined as "treatment not-Finish". OM was evaluated according to the Common Terminology Criteria for Adverse Events, version 4.0. D-index was compared between chemotherapeutic courses with versus without oral complications. D-index was significantly higher in chemotherapeutic courses with grade 1 or 2 OM (p odontogenic foci, and its occurrence does not relate to higher D-index.

    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

    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.

    Compounded lomustine is used commonly in veterinary patients. However, the potential variability in these formulations is unknown and concern exists that compounded formulations of drugs may differ in potency from Food and Drug Administration (FDA)-approved products. The initial objective of this study was to evaluate the frequency and severity of neutropenia in dogs treated with compounded or FDA-approved formulations of lomustine. Subsequent analyses aimed to determine the potency of lomustine obtained from several compounding pharmacies. Thirty-seven dogs treated with FDA-approved or compounded lomustine. Dogs that received compounded or FDA-approved lomustine and had pretreatment and nadir CBCs performed were eligible for inclusion. Variables assessed included lomustine dose, neutrophil counts, and severity of neutropenia. Lomustine 5 mg capsules from 5 compounding sources were tested for potency using high-pressure liquid chromatography (HPLC) with ultraviolet (UV) detection. Twenty-one dogs received FDA-approved lomustine and 16 dogs were treated with lomustine prescribed from a single compounding pharmacy. All dogs treated with FDA-approved lomustine were neutropenic after treatment; 15 dogs (71%) developed grade 3 or higher neutropenia. Four dogs (25%) given compounded lomustine became neutropenic, with 2 dogs (12.5%) developing grade 3 neutropenia. The potency of lomustine from 5 compounding pharmacies ranged from 50 to 115% of the labeled concentration, with 1 sample within ±10% of the labeled concentration. These data support broader investigation into the potency and consistency of compounded chemotherapy drugs and highlight the potential need for greater oversight of these products.

    Seeds of Nigella sativa (NS) are used to combat various disease conditions through their antibacterial effects. To evaluate the seeds' potential, we studied their effect on the prevention of febrile neutropenia (FN) in children with brain tumors. A randomized pretest-post-test control group study including 80 children (2-18 years) with brain tumors undergoing chemotherapy were equally allocated into two groups. Intervention group received 5 g of NS seeds daily throughout treatment while controls received nothing. CBC with differentials, incidence of FN, and LOS were noted on each follow-up. The majority of children 38/40 (95%), of the intervention group, took the seeds for 3-9 consecutive months. Eight out of 372 (2.2%) FN episodes were experienced by children of intervention group compared to controls 63/327 (19.3%) (p = 0.001) and a shorter LOS (median = 2.5 days) vs 5 days in the control group (p = 0.006). Children in both groups belonged to almost same geographical area with similar socio-economic background. Weights of children were almost equal at diagnosis. NS seeds showed a decrease in incidence of FN in children with brain tumors with shortening of subsequent LOS which may improve their outcome and thereby quality of life. Larger scale studies are needed to further evaluate the seeds' potential.

    New approaches of empirical antifungal therapy (EAT) in selected hematological patients with persistent febrile neutropenia (PFN) have been proposed in recent years, but their cost-effectiveness has not been studied. The aim of this study was to compare the cost-effectiveness of two different approaches of EAT in hematological patients with PFN: the diagnosis-driven antifungal therapy (DDAT) approach versus the standard approach of EAT. A decision tree to assess the cost-effectiveness of both approaches was developed. Outcome probabilities and treatment pathways were extrapolated from two studies: a prospective cohort study following the DDAT approach and a randomized clinical trial following the standard approach. Uncertainty was undertaken through sensitivity analyses and Monte Carlo simulation. The average effectiveness and economic advantages in the DDAT approach compared to the standard approach were 2.6% and €5,879 (33%) per PFN episode, respectively. The DDAT was the dominant approach in the 99.5% of the simulations performed with average cost-effectiveness per PFN episode of €32,671 versus €52,479 in the EAT approach. The results were robust over a wide range of variables. The DDAT approach is more cost-effective than the EAT approach in the management of PFN in hematological patients. PMID:23856767

Possuem tratamentos similares, na maioria dos casos necessitando de dilatação endoscópica, no entanto a resposta terapêutica, tempo ideal de tratamento, assim como intervalo entre as sessões podem ser variáveis. OBJETIVO: Analisar, do ponto de vista endoscópico, as estenoses benignas de esôfago em 14 anos de experiência no Hospital Universitário Clementino Fraga Filho da Universidade Federal do Rio de Janeiro, RJ, avaliando etiologia, a extensão da estenose, o número de dilatações necessário para atingir resposta terapêutica satisfatória, assim como a relação entre a extensão da estenose e a resposta terapêutica. MÉTODO: Foram analisadas 2.568 dilatações endoscópicas com uso de velas de Savary-Gilliard em 236 pacientes, durante um período de 14 anos e 10 meses, até junho de 2007. RESULTADOS: A estenose péptica foi a causa mais freqüentemente encontrada, seguida pela estenose cáustica. As estenoses longas e cáusticas necessitaram de maior número de sessões para ausência de disfagia. Estenoses pépticas e curtas responderam melhor a número menor de sessões de dilatação. CONCLUSÃO: A estenose péptica foi a causa mais comum e respondeu bem à terapia endoscópica, em concordância com a literatura. As estenoses cáusticas foram as mais refratárias, principalmente as longas. Quanto maior foi a extensão da estenose, também maior foi o número de sessões necessárias. Estenoses curtas apresentaram boa evolução na maioria dos casos. O número de dilatações necessárias dependeu diretamente da causa e da extensão da estenose.BACKGROUND: Benign esophageal strictures are complications that result from different causes.

    Variation in the management of fever and neutropenia (FN) in children is well described. The aim of this study was to explore the current management of FN across Australia and New Zealand and highlight areas for improvement. A practice survey was administered to paediatric health-care providers via four clinical and research networks. Using three clinical case vignettes, we explored risk stratification, empiric antibiotics, initial investigations, intravenous-oral switch, ambulatory management and antibiotic duration in children with cancer and FN. A response was received from 104 participants from 16 different hospitals. FN guideline compliance was rated as moderate or poor by 24% of respondents, and seven different fever definitions were described. There was little variation in the selected empiric monotherapy and dual-therapy regimens, and almost all respondents recommended first-dose antibiotics within 1 h. However, 27 different empiric antibiotic combinations were selected for beta-lactam allergy. An incorrect risk status was assigned to the low-risk case by 27% of respondents and to the high-risk case by 41%. Compared to current practice, significantly more respondents would manage the low-risk case in the ambulatory setting provided adequate resources were in place (43 vs. 85%, P < 0.0001). There was variation in the use of empiric glycopeptides as well as use of aminoglycosides beyond 48 h. Although the antibiotics selected for empiric management of FN are appropriate and consistent, variation and inaccuracies exist in risk stratification, the selection of monotherapy over dual therapy, empiric antibiotics chosen for beta-lactam allergy, use of glycopeptides and duration of aminoglycosides. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Studies have raised concern about the safety of generic compared with branded drugs. Febrile neutropenia (FN) resulting in hospital admission was compared between the branded docetaxel (Taxotere®, Sanofi) and 2 generic formulations (docetaxel Ebewe and docetaxel Hospira) in patients with breast cancer. This was a retrospective study that included patients with breast cancer who received docetaxel between January 2012 and December 2014. Patients who had an admission diagnosis of FN and had received docetaxel within 14 days prior to admission were evaluated. The docetaxel brand and dose, patient characteristics, hospital length of stay, admission to the intensive care unit (ICU), and mortality were recorded. During the study period, 2904 cycles of docetaxel were given for 876 patients (1519 cycles of docetaxel Sanofi, 811 cycles of docetaxel Hospira, and 574 cycles of docetaxel Ebewe). Among the cycles given, 130 cycles were associated with FN that required hospital admission. The overall incidence of FN resulting in hospital admission was significantly higher in patients who had received docetaxel Hospira, compared with patients who had received docetaxel Sanofi (47[5.8%] cycles vs 53 [3.5%] cycles, P = .009), but there was no significant difference between docetaxel Ebewe and docetaxel Sanofi (30[5.2%] cycles vs 53 [3.5%] cycles, P = .069). All cases of FN resolved except for 1 patient who died in the ICU after receiving docetaxel Ebewe. There was a significant difference in the incidence of FN between docetaxel Sanofi and docetaxel Hospira, but all cases in both groups resolved completely. © 2016, The American College of Clinical Pharmacology.

    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.

    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.

    Full Text Available Pathogenesis of dengue involves suppression of immune system leading to development of characteristic presentation of haematological picture of thrombocytopenia and leucopenia. Sometimes, this suppression in immune response is responsible for deterioration in clinical status of the patient in spite of all specific and supportive therapy. Certain drugs like steroids are used for rescue therapy in conditions like sepsis. We present a novel use of filgrastim as a rescue therapy in a patient with dengue hemorrhagic fever (DHF with acute respiratory distress syndrome (ARDS, myocarditis, and febrile neutropenia and not responding to standard management.

    With the emergence of biosimilar filgrastim to the market, there is a gradual decrease in the listed price of the originator product of filgrastim over the years, and this could have an impact on the cost-effectiveness of filgrastim in the treatment of febrile neutropenia (FN). A cost-effectiveness analysis would allow clinicians to make informed decision when considering the therapeutic filgrastim among low-risk FN patients. This study aims to evaluate the cost-effectiveness of adding therapeutic filgrastim to antibiotics in the treatment of established FN among patients with solid tumors and lymphomas. A decision tree model was created to compare two treatment options for established FN as follows: (1) antibiotics alone (standard care) and (2) antibiotics with therapeutic filgrastim (comparator). The target population was a hypothetical cohort of adult cancer patients with solid tumors or lymphomas hospitalized with FN in Singapore. The analysis was performed from a hospital's perspective over a 21-day time horizon. The main outcome measures included costs, quality-adjusted life year (QALY) and incremental cost-effectiveness ratio (ICER). One-way sensitivity analysis and probabilistic sensitivity analysis were conducted to evaluate the robustness of the results. Compared with antibiotics alone, the treatment strategy of antibiotics with therapeutic filgrastim was a dominant choice, incurring a cost saving of US$125 per patient (comparator versus standard care: US$9110 versus US$9235) and additional health benefit of 0.0007 QALY gained per patient (comparator versus standard care: 0.0450 versus 0.0443). Model results were robust against the parameter variations in the one-way sensitivity analyses, but increasing the cost of filgrastim beyond US$87 per injection would increase the ICER to >US$50,000/QALY. Furthermore, the strategy of antibiotics with therapeutic filgrastim was the preferred choice (dominant or cost-effective) in 83.7% of the model iterations at a

    We evaluated a 32 year-old woman whose oculocutaneous albinism, bleeding diathesis, neutropenia, and history of recurrent infections prompted consideration of the diagnosis of Hermansky-Pudlak syndrome type 2 (HPS-2). This was ruled out due to the presence of platelet delta granules and absence of AP3B1 mutations. Since parental consanguinity suggested an autosomal recessive mode of inheritance, we employed homozygosity mapping, followed by whole exome sequencing, to identify two candidate disease-causing genes, SLC45A2 and G6PC3. Conventional di-deoxy sequencing confirmed pathogenic mutations in SLC45A2, associated with oculocutaneous albinism type 4 (OCA-4), and G6PC3, associated with neutropenia. The substantial reduction of SLC45A2 protein in the patient’s melanocytes caused the mis-localization of tyrosinase from melanosomes to the plasma membrane and also led to the incorporation of tyrosinase into exosomes and secretion into the culture medium, explaining the hypopigmentation in OCA-4. Our patient’s G6PC3 mRNA expression level was also reduced, leading to increased apoptosis of her fibroblasts under ER stress. This report describes the first North American patient with OCA-4, the first culture of human OCA-4 melanocytes, and the use of homozygosity mapping followed by whole exome sequencing to identify disease-causing mutations in multiple genes in a single affected individual.

    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.

    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.

    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

    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.

Foram apresentados resultados das possíveis relações entre variáveis reprodutivas e o risco para DBM. Os casos e controles foram comparados levando em conta a idade na menarca e na menopausa, o número de gravidezes, de meses em que amamentaram e de ciclos menstruais ovulatórios, e os antecedentes familiares de câncer de mama. Mostraram influência significativa, em relação às DBM, a nuliparidade, aumentando o risco enquanto a idade de 30 ou mais anos no primeiro parto o reduziu; o número de ciclos ovulatórios, que foi significativamente maior para os casos, e a média de meses de uso de pílula, menor entre as mulheres com DBM. O uso de contraceptivos orais apresentou um efeito protetor apenas quando a duração total do uso foi maior que dois anos. Os resultados não se revelaram novos ou diferentes se comparados com outros estudos, mas confirmam a relativa concordância entre os fatores de risco para DBM e para câncer de mama, ainda que as relações entre esses fatores e as DBM não sejam tão claras como o são para o câncer, e existam também algumas discrepâncias.The purpose of the study was the identification of risk factors for benign breast diseases (BBD; 257 women with BBD diagnosed through pathological anatomy or citology and a matched control for each were studied.

    Background: Febrile neutropenia (FNP) is a condition defined by fever and neutropenia. There are current only limited data on related cutaneous manifestations. This study aimed to assess cutaneous lesions and their etiologies in a Thai group of FNP patients. Methods: A retrospective analysis was conducted on 43 non-transplant febrile neutropenic patients with concurrent cutaneous lesions, as determined by dermatopathologic studies at Songklanagarind Hospital in Thailand over a five-year period. Results: The mean age was 39 years (SD: 18.8). Approximately 60% were male. The most common underlying disease was a hematologic neoplasm. Twenty-one of the participants had developed FNP within 7.5±8.7 days after presenting with skin lesions. Twenty-two participants had skin lesions 9.0±11.1 days after FNP diagnosis. Cutaneous manifestations were mostly in the form of multiple lesions (67.4%), of which the most common were nodular skin lesions (37.2%) presenting on the lower extremities of the body (58.1%). The dermatopathologic diagnoses included infections which were almost all fungal and leukemia cutis. The development of skin lesions after FNP proved to be a statistically significant risk factor for fungal infection (OR 8.13, P = 0.009), whereas age (over 40 years) proved to be a statistically significant protective factor (OR 0.20, P = 0.04). Conclusions: There are a variety of cutaneous manifestations in FNP, of which the most common were cutaneous nodular skin lesions in the lower extremities. The most frequent infection was fungal in patients under 40 who had developed skin lesions after FNP. Creative Commons Attribution License

    Purpose To update a clinical practice guideline (CPG) for the empirical management of fever and neutropenia (FN) in children with cancer and hematopoietic stem-cell transplantation recipients. Methods The International Pediatric Fever and Neutropenia Guideline Panel is a multidisciplinary and multinational group of experts in pediatric oncology and infectious diseases that includes a patient advocate. For questions of risk stratification and evaluation, we updated systematic reviews of observational studies. For questions of therapy, we conducted a systematic review of randomized trials of any intervention applied for the empirical management of pediatric FN. The Grading of Recommendation Assessment, Development and Evaluation approach was used to make strong or weak recommendations and to classify levels of evidence as high, moderate, low, or very low. Results Recommendations related to initial presentation, ongoing management, and empirical antifungal therapy of pediatric FN were reviewed; the most substantial changes were related to empirical antifungal therapy. Key differences from our 2012 FN CPG included the listing of a fourth-generation cephalosporin for empirical therapy in high-risk FN, refinement of risk stratification to define patients with high-risk invasive fungal disease (IFD), changes in recommended biomarkers and radiologic investigations for the evaluation of IFD in prolonged FN, and a weak recommendation to withhold empirical antifungal therapy in IFD low-risk patients with prolonged FN. Conclusion Changes to the updated FN CPG recommendations will likely influence the care of pediatric patients with cancer and those undergoing hematopoietic stem-cell transplantation. Future work should focus on closing research gaps and on identifying ways to facilitate implementation and adaptation.

    Full Text Available Febrile neutropenia is a common and potentially life-threatening complication of treatment for childhood cancer, which has increasingly been subject to targeted treatment based on clinical risk stratification. Our previous meta-analysis demonstrated 16 rules had been described and 2 of them subject to validation in more than one study. We aimed to advance our knowledge of evidence on the discriminatory ability and predictive accuracy of such risk stratification clinical decision rules (CDR for children and young people with cancer by updating our systematic review.The review was conducted in accordance with Centre for Reviews and Dissemination methods, searching multiple electronic databases, using two independent reviewers, formal critical appraisal with QUADAS and meta-analysis with random effects models where appropriate. It was registered with PROSPERO: CRD42011001685.We found 9 new publications describing a further 7 new CDR, and validations of 7 rules. Six CDR have now been subject to testing across more than two data sets. Most validations demonstrated the rule to be less efficient than when initially proposed; geographical differences appeared to be one explanation for this.The use of clinical decision rules will require local validation before widespread use. Considerable uncertainty remains over the most effective rule to use in each population, and an ongoing individual-patient-data meta-analysis should develop and test a more reliable CDR to improve stratification and optimise therapy. Despite current challenges, we believe it will be possible to define an internationally effective CDR to harmonise the treatment of children with febrile neutropenia.

    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.

Há várias opções para o seu tratamento, porém as efetividades terapêuticas das mesmas permanecem controversas. OBJETIVO: Avaliar a efetividade terapêutica das manobras específicas disponíveis para o tratamento da VPPB. METODOLOGIA: Realizou-se uma busca eletrônica nas principais bases de dados, selecionando-se estudos clínicos randomizados envolvendo adultos com diagnóstico de VPPB confirmado com o teste de Dix-Hallpike e tratamento com manobras específicas (Epley ou Semont, por exemplo. Considerou-se como desfecho clínico a negativação do teste de Dix-Hallpike e a melhora das queixas subjetivas. Agruparam-se em metanálise os estudos com Escala de Jadad igual ou superior a três. RESULTADOS: Cinco estudos clínicos preencheram os critérios de inclusão, ou seja, ensaios randomizados de fase I comparando a manobra de Epley com placebos e controles. A metanálise mostra evidência dos efeitos benéficos da manobra de Epley para o tratamento do canal semicircular posterior (magnitude do efeito de 0,11 [IC 95% 0.05, 0.26] de melhora objetiva (Dix-Halpike após uma semana, 0.24 [IC 95% 0.13, 0.45] após um mês e 0.16 [IC 95% 0.08, 0.33] de melhora referida pelos pacientes após a primeira semana. CONCLUSÃO: Evidencia-se boa eficácia clínica da manobra de Epley para o tratamento da VPPB do canal semicircular posterior.

    Full Text Available Background: Lipegfilgrastim (Lonquex® has demonstrated to be non-inferior to pegfilgrastim (Neulasta® in reducing the duration of severe neutropenia (SN in patients with stage II−IV breast cancer. Compared to pegfilgrastim, lipegfilgrastim also demonstrated statistically significant lower time to ANC recovery in cycles 1–3, lower incidence of SN in cycle 2 and lower depth of absolute neutrophil count (ANC nadir in cycles 2 and 3. The aim of this study was to quantify the cost utility of lipegfilgrastim compared to pegfilgrastim in stage II−IV breast cancer patients, taking the perspective of the Belgian payer over a lifetime horizon.Methods: Two Markov models were developed to track on- and post-chemotherapy related complications, including SN, febrile neutropenia (FN, chemotherapy dose delay, chemotherapy relative dose intensity of less than 85%, infection, death rates, and quality-adjusted life years (QALYs. Data on costs (2015 value and effects were obtained from literature, national references, and complemented by a survey of clinical experts using a modified Delphi method. Both deterministic and probabilistic sensitivity analyses were carried out. Outcomes measures included costs, QALYs and life-years (LY.Results: At current equivalent price of €1,169, treatment with lipegfilgrastim was associated with overall costs of €9,845 vs. €10,208 for pegfilgrastim and overall QALYs of 13.977 vs. 13.925 for pegfilgrastim. Life expectancy was increased by 21 days (or 0.058 LY gained. The difference in costs stem from avoided infection, SN and FN cases in the lipegfilgrastim compared to the pegfilgrastim group. Similarly, the difference in QALYs was explained by the difference in the number of patients in the chemotherapy/G-CSF Markov state followed by infection and FN between lipegfilgrastim and pegfilgrastim. The probability of lipegfilgrastim to be cost-effective compared to pegfilgrastim was 68, 79, and 83% at the willingness

O risco de infecção relacionada com o tipo de neoplasia pode associarse 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 doentes 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

    The aim of the study was to evaluate the quantitative relationship between duration of severe neutropenia (DSN, the efficacy endpoint) and area under effect curve of absolute neutrophil counts (ANC-AUEC, the pharmacodynamic endpoint), based on data from filgrastim products, a human granulocyte colony-stimulating factor (G-CSF). Clinical data from filgrastim product comparator and test arms of two randomized, parallel-group, phase III studies in breast cancer patients treated with myelosuppressive chemotherapy were utilized. A zero-inflated Poisson regression model best described the negative correlation between DSN and ANC-AUEC. The models predicted that with 10 × 10 9 day/L of increase in ANC-AUEC, the mean DSN would decrease from 1.1 days to 0.93 day in Trial 1 and from 1.2 days to 1.0 day in Trial 2. The findings of the analysis provide useful information regarding the relationship between ANC and DSN that can be used for dose selection and optimization of clinical trial design for G-CSF.

    Full Text Available Clericuzio-type poikiloderma with neutropenia (PN is a rare genodermatosis associated with mutations in the C16orf57 gene, which codes for the uncharacterized protein hMpn1. We show here that, in both fission yeasts and humans, Mpn1 processes the spliceosomal U6 small nuclear RNA (snRNA posttranscriptionally. In Mpn1-deficient cells, U6 molecules carry 3′ end polyuridine tails that are longer than those in normal cells and lack a terminal 2′,3′ cyclic phosphate group. In mpn1Δ yeast cells, U6 snRNA and U4/U6 di-small nuclear RNA protein complex levels are diminished, leading to precursor messenger RNA splicing defects, which are reverted by expression of either yeast or human Mpn1 and by overexpression of U6. Recombinant hMpn1 is a 3′-to-5′ RNA exonuclease that removes uridines from U6 3′ ends, generating terminal 2′,3′ cyclic phosphates in vitro. Finally, U6 degradation rates increase in mpn1Δ yeasts and in lymphoblasts established from individuals affected by PN. Our data indicate that Mpn1 promotes U6 stability through 3′ end posttranscriptional processing and implicate altered U6 metabolism as a potential mechanism for PN pathogenesis.

    To describe treatment failure and mortality rates with different antibiotic regimens and different management strategies for empirical treatment of fever and neutropenia (FN) in pediatric patients with cancer and hematopoietic stem-cell transplantation (HSCT) recipients. We conducted a systematic review and performed searches of MEDLINE, Embase, PubMed, and Cochrane Central Register of Controlled Trials. Studies were included if pediatric patients had cancer or were HSCT recipients and the intervention was related to the management of FN. Strategies synthesized were monotherapy versus aminoglycoside-containing combination therapy; antipseudomonal penicillin monotherapy versus fourth-generation cephalosporin monotherapy; inpatient versus outpatient management; oral versus intravenous antibiotics; and addition of colony-stimulating factors. Of 11,469 citations screened, 68 studies randomly assigning 7,265 episodes were included. When compared with monotherapy, aminoglycoside-containing combination therapy did not decrease treatment failures (risk ratio, 1.13; 95% CI, 0.92 to 1.38; P = 0.23), and no difference in mortality was observed. Antipseudomonal penicillin and fourth-generation cephalosporin monotherapy were associated with similar failure and mortality rates. Outpatient management and oral antibiotics were safe in low-risk FN with no infection-related mortality observed in any patient and no significant differences in outcomes compared with inpatient management and intravenous therapy. Therapeutic colony-stimulating factors were associated with a 1.42-day reduction in hospitalization (95% CI, 0.62 to 2.22 days; P pediatric randomized trials of FN management. Monotherapy for high-risk FN and outpatient and oral management for low-risk FN are effective strategies. These findings will provide the basis for guideline recommendations in pediatric FN. © 2016 by American Society of Clinical Oncology.

    The purpose of this study is to assess temporal trends in the use of granulocyte colony-stimulating factor (G-CSF) prophylaxis and risk of febrile neutropenia (FN) among older women receiving adjuvant chemotherapy for early-stage breast cancer. Women aged ≥ 66 years with diagnosis of early-stage breast cancer who initiated selected adjuvant chemotherapy regimens were identified using the SEER-Medicare data from 2002 to 2012. Adjusted, calendar-year-specific proportions were estimated for use of G-CSF primary prophylaxis (PP) and secondary prophylaxis and FN risk in the first and the second/subsequent cycles during the first course of chemotherapy, using logistic regression models. calendar-year-specific mean probabilities were estimated with covariates set to modal values. Among 11,107 eligible patients (mean age 71.7 years), 74% received G-CSF in the first course of chemotherapy. Of all patients, 5819 (52%) received G-CSF PP, and among those not receiving G-CSF PP, only 5% received G-CSF secondary prophylaxis. The adjusted proportion using G-CSF PP increased from 6% in 2002 to 71% in 2012. During the same period, the adjusted risk of FN in the first cycle increased from 2% to 3%; the adjusted risk increased from 1.5% to 2.9% among those receiving G-CSF PP and from 2.3% to 3.5% among those not receiving G-CSF PP. The use of G-CSF PP increased substantially during the study period. Although channeling of higher-risk patients to treatment with G-CSF PP is expected, the adjusted risk of FN among patients treated with G-CSF PP tended to be lower than among those not receiving G-CSF PP.

    To study dapsone in comparison with trimethoprim/sulfamethoxazole (TMP/SMX) for Pneumocystis jiroveci (PJP) prophylaxis in children with acute lymphoblastic leukemia (ALL). A retrospective study with a prospective follow-up. Pediatric ALL patients diagnosed between May 2009 and May 2014, who are still receiving or have completed their maintenance chemotherapy. Patients who completed chemotherapy were prospectively followed up for neutropenia. TMP/SMX was used as the initial PJP prophylaxis. An alternative drug was indicated if the patient remained cytopenic for >3 weeks. Average absolute neutrophilic count (ANC), average % of oral mercaptopurine (6-MP), and methotrexate doses were calculated over a period of 6 months before and after shifting to dapsone. Sixty-two ALL patients were eligible for analysis. Twenty-four patients (38.7%) received TMP/SMX for PJP prophylaxis, whereas 34 patients received Dapsone (54.8%). Only 3 patients received IV pentamidine (4.8%), whereas 1 patient (1.6%) received atovaquone. The incidence of prophylaxis failure was 1/1041 months on TMP/SMX and 1/528 months on dapsone. After shifting to dapsone, patients maintained significantly higher ANC (1.46±0.46 vs. 1.17±0.40, P=0.0053), and received significantly higher doses of 6-MP (62.61%±11.45 vs. 57.45±10.14, P=0.0081) and methotrexate (64.9%±14.29 vs. 56.5%±9.9, P=0.0176), with a significantly shorter duration of chemotherapy interruption (1.94±1.2 vs. 3.25±1.29 wk, P=0.0002). Dapsone for PJP prophylaxis in ALL allowed patients to maintain higher ANC and to receive higher doses of chemotherapy, while maintaining a low incidence of PJP breakthrough infection.

    Early breast cancer is commonly treated with anthracyclines and taxanes. However, combining these drugs increases the risk of myelotoxicity and may require granulocyte colony-stimulating factor (G-CSF) support. The highest incidence of febrile neutropenia (FN) and largest benefit of G-CSF during the first cycles of chemotherapy lead to questions about the effectiveness of continued use of G-CSF throughout later cycles of chemotherapy. In a multicenter study, patients with breast cancer who were considered fit enough to receive 3-weekly polychemotherapy, but also had > 20% risk for FN, were randomly assigned to primary G-CSF prophylaxis during the first two chemotherapy cycles only (experimental arm) or to primary G-CSF prophylaxis throughout all chemotherapy cycles (standard arm). The noninferiority hypothesis was that the incidence of FN would be maximally 7.5% higher in the experimental compared with the standard arm. After inclusion of 167 eligible patients, the independent data monitoring committee advised premature study closure. Of 84 patients randomly assigned to G-CSF throughout all chemotherapy cycles, eight (10%) experienced an episode of FN. In contrast, of 83 patients randomly assigned to G-CSF during the first two cycles only, 30 (36%) had an FN episode (95% CI, 0.13 to 0.54), with a peak incidence of 24% in the third cycle (ie, first cycle without G-CSF prophylaxis). In patients with early breast cancer at high risk for FN, continued use of primary G-CSF prophylaxis during all chemotherapy cycles is of clinical relevance and thus cannot be abandoned.

    Induction chemotherapy with docetaxel improved outcome in advanced head and neck squamous cell carcinoma (HNSCC) patients, but docetaxel was not recommended in liver dysfunction patients for treatment toxicities. Severe neutropenic events (SNE) including severe neutropenia (SN) and febrile neutropenia (FN) still developed in these patients with normal serum transaminases. Ultrasonography (US) fibrotic score represented degree of hepatic parenchymal damage and showed good correlation to fibrotic changes histologically. This study aims to evaluate the association of US fibrotic score with docetaxel treatment-related SNE in advanced HNSCC patients with normal serum transaminases. Between 1 January 2011 and 31 December 2013, a total of 47 advanced HNSCC patients treated with induction docetaxel were enrolled. The clinical features were collected to assess predictive factors for SNE. The patients were divided into two groups by the US fibrotic score with a cutoff value of 7. The Mann-Whitney U test and logistic regression method were used for the risk factor analysis. The background, treatment, and response were similar in both groups except for lower lymphocyte and platelet count in patients with higher US score. Twenty-seven patients (51 %) developed grade 3/4 neutropenia, and more SNE developed in patients with US score ≧7. In multivariate analysis, only US score ≥7 was independent predictive factor for developing SN (hazard ratio 7.71, p = 0.043) and FN (hazard ratio 20.95, p = 0.008). US score ≥7 is an independent risk factor for SNE in advanced HNSCC patients treated with induction docetaxel. US score could be used for risk prediction of docetaxel-related SNE.

    Full Text Available Abstract Background Poikiloderma with Neutropenia (PN is a rare autosomal recessive genodermatosis caused by C16orf57 mutations. To date 17 mutations have been identified in 31 PN patients. Results We characterize six PN patients expanding the clinical phenotype of the syndrome and the mutational repertoire of the gene. We detect the two novel C16orf57 mutations, c.232C>T and c.265+2T>G, as well as the already reported c.179delC, c.531delA and c.693+1G>T mutations. cDNA analysis evidences the presence of aberrant transcripts, and bioinformatic prediction of C16orf57 protein structure gauges the mutations effects on the folded protein chain. Computational analysis of the C16orf57 protein shows two conserved H-X-S/T-X tetrapeptide motifs marking the active site of a two-fold pseudosymmetric structure recalling the 2H phosphoesterase superfamily. Based on this model C16orf57 is likely a 2H-active site enzyme functioning in RNA processing, as a presumptive RNA ligase. According to bioinformatic prediction, all known C16orf57 mutations, including the novel mutations herein described, impair the protein structure by either removing one or both tetrapeptide motifs or by destroying the symmetry of the native folding. Finally, we analyse the geographical distribution of the recurrent mutations that depicts clusters featuring a founder effect. Conclusions In cohorts of patients clinically affected by genodermatoses with overlapping symptoms, the molecular screening of C16orf57 gene seems the proper way to address the correct diagnosis of PN, enabling the syndrome-specific oncosurveillance. The bioinformatic prediction of the C16orf57 protein structure denotes a very basic enzymatic function consistent with a housekeeping function. Detection of aberrant transcripts, also in cells from PN patients carrying early truncated mutations, suggests they might be translatable. Tissue-specific sensitivity to the lack of functionally correct protein accounts for the

    Invasive fungal disease (IFD) causes significant morbidity and mortality in hematologic malignancy patients with high-risk febrile neutropenia (FN). These patients therefore often receive empirical antifungal therapy. Diagnostic test-guided pre-emptive antifungal therapy has been evaluated as an alternative treatment strategy in these patients. We conducted an electronic search for literature comparing empirical versus pre-emptive antifungal strategies in FN among adult hematologic malignancy patients. We systematically reviewed 9 studies, including randomized-controlled trials, cohort studies, and feasibility studies. Random and fixed-effect models were used to generate pooled relative risk estimates of IFD detection, IFD-related mortality, overall mortality, and rates and duration of antifungal therapy. Heterogeneity was measured via Cochran's Q test, I2 statistic, and between study τ2. Incorporating these parameters and direct costs of drugs and diagnostic testing, we constructed a comparative costing model for the two strategies. We conducted probabilistic sensitivity analysis on pooled estimates and one-way sensitivity analyses on other key parameters with uncertain estimates. Nine published studies met inclusion criteria. Compared to empirical antifungal therapy, pre-emptive strategies were associated with significantly lower antifungal exposure (RR 0.48, 95% CI 0.27-0.85) and duration without an increase in IFD-related mortality (RR 0.82, 95% CI 0.36-1.87) or overall mortality (RR 0.95, 95% CI 0.46-1.99). The pre-emptive strategy cost $324 less (95% credible interval -$291.88 to $418.65 pre-emptive compared to empirical) than the empirical approach per FN episode. However, the cost difference was influenced by relatively small changes in costs of antifungal therapy and diagnostic testing. Compared to empirical antifungal therapy, pre-emptive antifungal therapy in patients with high-risk FN may decrease antifungal use without increasing mortality. We

    Evaluate the cost-effectiveness of primary vs secondary prophylaxis (PP vs SP) with pegfilgrastim to reduce the risk of febrile neutropenia (FN) in Non-Hodgkin's Lymphoma (NHL) patients receiving myelosuppressive chemotherapy from a US payer perspective. A Markov model was used to compare PP vs SP with pegfilgrastim in a cohort of patients receiving six cycles of cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) or CHOP plus rituximab (CHOP-R) chemotherapy. Model inputs, including efficacy of pegfilgrastim in reducing risk of FN and costs, were estimated from publicly available sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per life-year saved (LYS), per quality-adjusted life-year (QALY) gained, and per FN event avoided over a lifetime horizon. Deterministic and probabilistic analyses were performed to assess sensitivity and robustness of results. Lifetime costs for PP were $5000 greater than for SP; however, PP was associated with fewer FN events and more LYs and QALYs gained vs SP. Incremental cost-effectiveness ratios (ICERs) for PP vs SP for CHOP were $13,400 per FN event avoided, $29,500 per QALY gained, and $25,800 per LYS. CHOP-R results were similar ($15,000 per FN event avoided, $33,000 per QALY gained, and $28,900 per LYS). Results were most sensitive to baseline FN risk, cost per FN episode, and odds ratio for reduced relative dose intensity due to prior FN event. PP was cost-effective vs SP in 85% of simulations at a $50,000 per QALY threshold. In the absence of NHL-specific data, estimates for pegfilgrastim efficacy and relative risk reduction of FN were based on available data for neoadjuvant TAC in patients with breast cancer. Baseline risks of FN for CHOP and CHOP-R were assumed to be equivalent. PP with pegfilgrastim is cost-effective compared to SP with pegfilgrastim in NHL patients receiving CHOP or CHOP-R.

    The objective of this study was to evaluate the cost effectiveness of no prophylaxis, primary prophylaxis (PP), or secondary prophylaxis (SP) with granulocyte colony-stimulating factors (G-CSFs), i.e., pegfilgrastim, lipegfilgrastim, filgrastim (6- and 11-day), or lenograstim (6- and 11-day), to reduce the incidence of febrile neutropenia (FN) in patients with stage II breast cancer receiving TC (docetaxel, cyclophosphamide) and in patients with non-Hodgkin lymphoma (NHL) receiving R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) over a lifetime horizon from a Belgian payer perspective. A Markov cycle tree tracked FN events during chemotherapy (3-week cycles) and long-term survival (1-year cycles). Model inputs, including the efficacy of each strategy, risk of reduced relative dose intensity (RDI), and the impact of RDI on mortality, utilities, and costs (in €; 2014 values) were estimated from public sources and the published literature. Incremental cost-effectiveness ratios (ICERs) were assessed for each strategy for costs per FN event avoided, life-year (LY) saved, and quality-adjusted LY (QALY) saved. LYs and QALYs saved were discounted at 1.5% annually. Deterministic and probabilistic sensitivity analyses (DSAs and PSAs) were conducted. Base-case ICERs for PP with pegfilgrastim relative to SP with pegfilgrastim were €15,500 per QALY and €14,800 per LY saved for stage II breast cancer and €7800 per QALY and €6900 per LY saved for NHL; other comparators were either more expensive and less effective than PP or SP with pegfilgrastim or had lower costs but higher ICERs (relative to SP with pegfilgrastim) than PP with pegfilgrastim. Results of the DSA for breast cancer and NHL comparing PP and SP with pegfilgrastim indicate that the model results were most sensitive to the cycle 1 risk of FN, the proportion of FN events requiring hospitalization, the relative risk of FN in cycles ≥2 versus cycle 1, no history of FN, and the

    Full Text Available A síndrome epiléptica em chagásicos crônicos, foi referida raramente na literatura especializazda, não tendo sido feito até o momento, um estudo detalhado das suas manifestações. Partindo-se da premissa de que a moléstia de Chagas tem por substrato anatômico uma destruição neuronal, procurou-se comparar dois grupos de epilépticos, um dos quais com moléstia de Chagas crônica. Foram estudados 167 pacientes epilépticos, dos quais 44 eram comprovadamente chagásicos. O estudo permitiu coletar dados referentes à procedência dos pacientes, resultado soro-lógico, sexo, idade, época de incidência das manifestações epilépticas, elementos dos exames neurológicos, do líquido cefalorraqueano, eletrencefalográfico e os resultados da terapêutica anticonvulsivante. Como resultados principais destacamos o início tardio da epilepsia nos chagásicos, e o predomínio acentuado das crises parciais com sintomatologia elementar de tipo autonômico. O exame neurológico e o do líquido cefalorraqueano, apesar de apresentarem percentualmente nos seus resultados, taxas moderadamente mais elevadas na incidência de alterações, não caracterizaram síndromes neurológicas bem definidas. O exame eletrencefalográfico, revelou alterações sugestivas de comprometimento orgânico cerebral difuso. A terapêutica anticonvulsivante, baseada na utilização de hidantoinatos, barbitúricos, primidona e benzodiazepínicos, mostrou que o controle das crises foi mais difícil nos chagásicos, exigindo maiores quantidades de medicação, com resultados menos satisfatórios.

    One hundred thirteen children referred for chronic constipation were examined by means of diagnostic work-up including anal inspection, rectal exploration, weekly bowel frequency evaluation, measurement of total and segmental intestinal transit times (TITT, SITT), contrast enema anorectal manometry (ARM), suction rectal biopsy for histochemistry. Final diagnosis were: chronic functional simple constipation in 53 children; chronic functional constipation and soiling in 32; Hirschsprung's disease in 18. In 10 children, initially referred for constipation, TITT was in the normal range so they underwent no further examination. Conclusions are that bowel frequency identifies a real gastrointestinal problem, but definite diagnosis of constipation is relied on TITT. In the assessment of chronic constipation nature, ARM is more sensitive than radiology. Suction rectal biopsy is reliable in detection of aganglionosis: its accuracy can be improved by histochemical or biochemical determination of Acetylcholinoesterase

    Full Text Available This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.Esse estudo avaliou ações motoras manuais sequenciais em crianças com epilepsia focal benigna da infância com descarga centrotemporal (EBICT e comparou os resultados com o grupo controle pareado, através do teste de Lúria (punho-lado-palma. As crianças com EBICT realizaram single photon emission computed tomography (SPECT interictal e Teste de Desempenho Escolar (TDE. Foram encontradas diferenças significativas entre os dois grupos nas atividades motoras de três movimentos iguais e três movimentos diferentes. As crianças com piores resultados no TDE e com SPECT alterado apresentaram mais erros no teste de imitação manual. Crianças com epilepsia fracassaram nos testes de avaliação motora que envolvem programação/planejamento. Esse estudo sugere que mudanças funcionais relacionadas à atividade epileptiforme na região rolândica interfere com as funções executivas de crianças com EBICT.

O teste de PCR detectou o H. pylori em 27,5% (22/80 das lesões gástricas benignas e em 50% (9/18 dos adenocarcinomas gástricos, com diagnóstico histológico negativo para essa bactéria. Cerca de 2,5% das amostras, exclusivamente de lesões benignas, com diagnóstico histológico positivo apresentaram resultado molecular negativo, para ambos os primers. Diferenças estatisticamente significantes foram encontradas entre os métodos histológico e molecular, em metaplasia intestinal (p = 0,0461 e adenocarcinoma gástrico (p = 0,0011, devido à subdetecção do H. pylori pelo método histológico, e provavelmente pela baixa densidade da bactéria conseqüente à atrofia severa da mucosa gástrica, nesses dois tipos de lesões. Nossos achados demonstram que o método de PCR é mais eficaz para diagnosticar a infecção por H. pylori, principalmente, em metaplasia intestinal e adenocarcinoma gástrico.

    Caspofungin is approved in the United States for empiric antifungal therapy for persistent febrile neutropenia (FN). There are limited data about the use of other echinocandins in this setting. After a formulary change, we retrospectively evaluated the safety and effectiveness of caspofungin and micafungin as empiric antifungal therapy for FN at Brigham and Women's Hospital (Boston, Massachusetts). This was a retrospective, observational, sequential cohort study. We identified patients who had received >or=2 doses on concurrent days of either caspofungin (between November 2005 and October 2006) or micafungin (between November 2006 and October 2007) for empiric FN therapy. Patients were included for analysis if they were neutropenic (absolute neutrophil count or=100.5 degrees F [>or=38 degrees C]). Patients without previous exposure to an echinocandin were included; those included in the caspofungin cohort were excluded from the micafungin cohort. Those who had previously received another systemic antifungal agent for FN therapy (except fluconazole for mucosal candidiasis) were excluded. Patients were followed through hospital discharge. Outcomes analyzed were successful treatment of baseline invasive fungal disease (IFD), incidence of breakthrough IFD, overall mortality, and discontinuation because of adverse events (AEs). IFD was diagnosed and classified according to current European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group Consensus Group criteria. Three hundred twenty-three patients met inclusion criteria (caspofungin, n = 149; micafungin, n = 174). Median age was 49 years in both the caspofungin and micafungin groups; 80 (53.7%) and 99 (56.9%) patients in each group, respectively, were men. Fluconazole prophylaxis had been administered to 30 patients (20.1%) treated with caspofungin and 21 patients (12.1%) treated with

Foram estudadas 27 crianças com diagnósticos de EBICT. Foi realizado o eletrecenfalograma durante vigília, em repouso, e selecionadas cerca de 20 janelas com 2,56 s. Foram calculados os valores de potência absoluta e relativa nas faixas delta, teta, alfa e beta. Os resultados foram comparados aos de 27 crianças sadias pareadas quanto a idade e escolaridade materna. A potência absoluta foi significativamente maior no grupo EBICT nas nas bandas delta e teta para a quase totalidade dos eletrodos e para alguns eletrodos nas faixas alfa e beta. A potência relativa teta foi também maior no grupo EBICT na maioria dos eletrodos. Esses achados sugerem que na EBICT, embora a atividade epileptiforme seja focal. Ocorrem modificações funcionais difusas que incluem alterações do perfil da distribuição das faixas de frequência, com maior potência relativa teta.Quantitative EEG aspects are studied in children with benign childhood epilepsy with centrotempral spikes (BCET. A total of 27 children, from 7 to 11 years neurologically and intellectually normal was studied and compared to a control group of normal children. They were submitted to anamnesis, neurological examination, Raven test, digital electroencephalogram and quantitative eletroencephalogram analysis. There was a higher delta, theta, alpha and beta absolute power in most of the electrodes and of alpha and beta for some electrodes in the BCET group. Relative theta power was also higher for the BECT group in most of the electrodes. These findings suggest that in BECT there are diffuse differences form age-matched normal children including a difference in relative spectrum of electrical cerebral activity and that this may be related to a functional immaturity.

    implications for the management of febrile neutropenia, especially in breakthrough bacteremia and fever when patients are already on broadspectrum antibiotics. Emergence of resistance to 3GCs and, to a lesser extent, to carbapenems in GN isolates has to be considered seriously in our local guidelines for empiric treatment of febrile neutropenia, especially given that their occurrence was proven to be associated with poorer outcomes.

    The aim of this study was to investigate the mannose-binding lectin 2 (MBL-2), interleukin (IL)-4, Toll-like receptor 4 (TLR-4), angiotensin converting enzyme (ACE), chemokine receptor 5 (CCR-5), and IL-1 receptor antagonist (RA) gene polymorphisms (GPs) in acute leukemias (ALs) and to evaluate their roles in febrile neutropenia (FN) resulting from chemotherapy. The study included 60 AL patients hospitalized between the period of July 2001 and August 2006. Polymorphisms for the genes ACE(I/D), CCR-5, IL-1RA, MBL-2, TLR-4, and IL-4 were typed by polymerase chain reaction (PCR) and/or PCR-restriction fragment length polymerase. Genotype frequencies for these genes were compared in the patient and control groups. The relationships between the genotypes and the body distribution of infections, pathogens, the duration of neutropenia, and febrile episodes in AL patients were evaluated. No significant differences in either the genotype distribution or the allelic frequencies of TLR-4, IL-4, CCR-5, IL-1RN GPs were observed between patients and healthy controls. The AB/BB genotype (53.3%) in the MBL-2 gene was found to be significantly higher in the AL patients compared with control groups. There were correlations between the presence of MBL-2, TLR-4, and ACE polymorphisms and clinical parameters due to FN. Overall, bacteremia was more common in MBL BB and ACE DD. Gram-positive bacteremia was more common in ACE for ID versus DD genotype. Gram-negative bacteremia was more common for both the MBL-2 AB/BB genotype and TLR-4 AG genotype. Median durations of febrile episodes were significantly shorter in ACE DD and MBL AB/BB. Although TLR-4, ACE, and MBL-2 GPs have been extensively investigated in different clinical pictures, this is the first study to evaluate the role of these polymorphisms in the genetic etiopathogenesis of FN in patients with ALs. As a conclusion, TLR-4, ACE, and MBL-2 genes might play roles in the genetic etiopathogenesis of FN in patients with ALs.

    Full Text Available Benign childhood epilepsy with centro-temporal spikes (BECTS is a form of epilepsy with no demonstrable anatomical lesion showing spontaneous seizure remission. During the active phase of the disease the children may show cognitive deficits. The objective of this study was to assess, in children with BECTS, the relationship between clinical-EEG aspects and performance in the school performance test (SPT, Raven's progressive matrixes test and the Wechsler Intelligence Scale for Children (WISC-III. Forty-two 7 to 11 year old children were included and the following tests carried out: anamnesis, neurological examination, electroencephalogram (EEG, SPT, Raven's test and WISC-III. The children with BECTS had normal IQ values but showed inferior performance in the SPT more frequently than "healthy" children, paired with respect to age and maternal scholastic level. There was moderate positive correlation between WISC-III results and the age when the seizures started and the educational level of the parents. On the other hand, aspects linked to the epileptic nature of BECTS, such as the number of seizures, time since last seizure and the number and lateralization of the centro-temporal spikes on the EEG, showed no correlation with the neuropsychological tests.A epilepsia benigna da infância com pontas centrotemporais (EBICT é uma forma de epilepsia na qual não existem lesões anatômicas demonstráveis e há remissão espontânea das crises.

    Apoptosis is induced by binding of death receptor ligands, members of the tumor necrosis factor (TNF) superfamily, to their cognate receptors. It is suggested that TNF-related apoptosis inducing ligand (TRAIL) is involved in pathogenesis of juvenile-onset systemic lupus erythematosus (JSLE). This study aimed to assess TRAIL concentrations in sera of JSLE children and to determine their potential relationship with disease activity, anti-double-stranded DNA (anti-dsDNA) levels, neutropenia and renal involvement. Circulating levels of TRAIL were measured by enzyme-linked immunosorbent assay (ELISA) in serum samples obtained from 40 JSLE patients (20 with active and 20 with inactive disease) and 20 controls. The mean (SEM) serum TRAIL concentration in JSLE was 1750.7 (440.2) pg/mL. Serum TRAIL concentrations in patients were higher than those in controls (P nephritis compared to classes I and II nephritis (1970 [512] vs. 1330 [331] pg/mL; P lupus nephritis. © 2013 The Authors International Journal of Rheumatic Diseases © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

MÉTODOS Utilizando modelo de Markov, construiu-se coorte hipotética de 40 anos para pacientes HBeAg-positivo ou HBeAg-negativo. Foram comparados os usos de adefovir, entecavir, tenofovir e lamivudina (com terapia de resgate em caso de resistência viral para tratamento de pacientes adultos com hepatite B crônica, virgens de tratamento, com elevados níveis de alanina aminotransferase, sem evidência de cirrose e sem coinfecção por HIV. Valores para custo e efeito foram obtidos da literatura. A medida do efeito foi expressa em anos de vida ganhos (AVG. Taxa de desconto de 5% foi aplicada. Análise de sensibilidade univariada foi conduzida para avaliar incertezas do modelo. RESULTADOS O tratamento inicial com entecavir ou tenofovir apresentou melhores resultados clínicos. As menores razões custo-efetividade foram de entecavir para pacientes HBeAg-positivo (R$ 4.010,84/AVG e lamivudina para pacientes HBeAg-negativo (R$ 6.205,08/AVG. Para pacientes HBeAg-negativo, a razão custo-efetividade incremental de entecavir (R$ 14.101,05/AVG está abaixo do limiar recomendado pela Organização Mundial da Saúde. Análise de sensibilidade mostrou que variação nos custos dos medicamentos pode tornar tenofovir alternativa custo-efetiva tanto para pacientes HBeAg-positivo quanto para HBeAg-negativo. CONCLUSÕES Entecavir é alternativa recomendada para iniciar o tratamento de pacientes com hepatite B crônica no Brasil. Contudo, se houver redução no custo de tenofovir, esta pode se tornar alternativa mais custo-efetiva.

    Full Text Available A prevalência de doença crônica na infância tem aumentado, impondo à família contato contínuo com profissionais de saúde, ocasião em que a relação desempenha papel relevante. Raras explorações científicas abordam tal temática, apesar de ser apontada como núcleo fundamental para a interação efetiva. O objetivo desse estudo foi caracterizar como a família de criança doente crônica percebe sua relação com os profissionais de saúde. Foram entrevistados 20 cuidadores de criança com doença crônica. O referencial teórico e metodológico adotados foram, respectivamente, o Interacionismo Simbólico e a análise de conteúdo temática. O processo analítico revelou quatro categorias temáticas: papel do cuidador, relações angustiantes, serviços e profissionais e buscando relações acolhedoras. O resultado deste processo interacional que apresenta incongruência de expectativas e comportamentos entre profissional e família é falho e gera sentimento de desamparo, o qual é amenizado pela escuta e compreensão de outras famílias em situação similar.

    Full Text Available Fundamento: Pacientes com insuficiência cardíaca (IC apresentam disfunção ventricular esquerda e redução da pressão arterial média (PAM. O aumento do estímulo adrenérgico causa vasoconstrição e resistência dos vasos, mantendo a PAM, enquanto aumenta a resistência vascular periférica e a rigidez dos vasos condutores. O aumento da pressão de pulso (PP reflete a complexa interação do coração com os sistemas arteriais e venosos. O aumento da PP é um importante marcador de risco em pacientes com insuficiência cardíaca crônica (ICC. A ventilação não invasiva (VNI tem sido utilizada para IC aguda descompensada para melhorar a congestão e a ventilação pelos efeitos respiratórios e hemodinâmicos. No entanto, nenhum desses estudos relatou o efeito da VNI na PP. Objetivo: O objetivo deste estudo foi determinar os efeitos agudos da VNI com CPAP (pressão positiva contínua nas vias aéreas sobre a PP em pacientes ambulatoriais com ICC. Métodos: Seguindo um protocolo randomizado, duplo-cego, cruzado e controlado com placebo, 23 pacientes com ICC (17 homens, 60 ± 11 anos, IMC 29 ± 5 kg/cm2, classes II e III da NYHA foram submetidos à CPAP via máscara nasal durante 30 minutos na posição reclinada. A pressão da máscara foi de 6 cmH2O, enquanto o placebo foi fixado em 0-1 cmH2O. PP e outras variáveis hemodinâmicas não invasivas foram avaliadas antes, durante e depois do placebo e do modo CPAP.

    Full Text Available Se efectuaron potenciales evocados visuales (PEV en sus variantes flash (F y pattern (P, en 17 pacientes afectados de enfermedad de Chagas crónica. La edad del grupo se halló comprendida entre los 21 y 65 anos. Se incluyeron pacientes con período de evolución mayor de 7 anos y dos serologías positivas como mínimo. La selección fue descartando a los portadores de diabetes, alcoholismo, lepra, sífilis y enfermedades degenerativas del sistema nervioso central, como así intoxicaciones de diversas etiologías y afecciones visuales detectadas en el exámen oftalmológico. Todos fueron estudiados con exámenes clínicos y complementarios de rutina, electrocardiograma, exámen oftalmológico y específicos como la reacción de Machado-Guerreiro, test de inmunofluorescência y test de hemoaglutinación. Los resultados de los PEV mostraron fundamentalmente alteraciones en la morfología del trazado y disminución de la amplitud dei potencial, en el 35% de los pacientes estudiados. Estas alteraciones electroneurofisiológicas permitirían inferir correlación a los hallazgos anatomopatológicos, que muestran perdida de grupos neuronales en autópsias de pacientes chagásicos crónicos.

    Neutropenic complications are the primary dose-limiting toxic effects observed in patients treated with systemic cancer chemotherapy. Broad-spectrum antibiotic therapy should be promptly administered to patients with febrile neutropenia (FN). The risk assessment of FN includes the disease characteristics, chemotherapy regimen, individual patient risk factors, and treatment intent. After considering such risk factors of FN, clinicians should appropriately consider the use of granulocytecolony stimulating factor (G-CSF) as a prophylactic or therapeutic measure. Some types of lymphoma can be cured with chemotherapy. The incidence of FN in patients receiving the standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen is approximately 20%. Primary prophylactic use of G-CSF is recommended for patients aged ≥ 65 years having diffuse aggressive lymphoma and treated with curative chemotherapy in an effort to improve their quality of life (QOL). Primary prophylaxis is recommended for the prevention of FN in patients at high risk, on the basis of factors other than age. G-CSF should be avoided in patients receiving concomitant chemotherapy and radiation therapy, particularly in those with cancer involving the mediastinum. The adverse events of G-CSF are generally graded mild to moderate; however, rare life-threatening adverse effects have been published in the literature. A clinical practice guideline for the use of G-CSF was published by the Japan Society of Clinical Oncology in 2013. On the basis of this guideline, the above issues have been discussed in this paper.

    La Próstata Desconocida

    Los médicos de la antigüedad reconocieron el fenómeno de la retención urinaria, pero en general atribuyeron esta condición a la presencia de cálculos vesicales. Su apreciación de la anatomía humana fue muy limitada y el significado potencial de la próstata en la retención urinaria no se realizó por muchos siglos. Ciertamente, la próstata fue identificada solamente durante la edad media y el renacimiento. En ese entonces no obstante las teorías fueron dominadas por el concepto de carnosidades y carúnculas y muy poco avance ocurrió en el conocimiento de las causas de la retención urinaria en el hombre.

    Full Text Available A hipertrofia idiopática do músculo masseter (HIM é uma patologia pouco freqüente e de causa desconhecida. Alguns autores correlacionam tal condição com hábitos de mascar gomas, disfunção da articulação temporomandibular (ATM, hipertrofias congênitas e funcionais, e distúrbios emocionais (nervosismo e ansiedade. A maioria dos pacientes queixa-se da alteração estética decorrente da assimetria facial, também chamada "face quadrada", no entanto, sintomas como trismo, protrusão e bruxismo também podem ocorrer. Os objetivos deste estudo foram: relatar um caso de HIM e descrever a sintomatologia e o tratamento realizado. O paciente relatava aumento bilateral na região do ângulo da mandíbula de evolução lenta e progressiva. Negava dor ou desconforto, porém se queixava de otalgia bilateral, trismo noturno e ansiedade. Ao exame físico, observou-se hipertrofia bilateral de masseter sem alterações inflamatórias no local. Foi indicado tratamento cirúrgico com abordagem extra-oral. Exames complementares são indicados na dúvida diagnóstica. A conduta terapêutica varia de conservadora a cirúrgica, sendo que esta depende principalmente da experiência e da habilidade do cirurgião.Idiopathic hypertrophy of the masseter muscle is a rare disorder of unknown cause. Some authors associate it with the habit of chewing gum, temporo-mandibular joint disorder, congenital and functional hypertrophies, and emotional disorders (stress and nervousness. Most patients complain of the cosmetic change caused by facial asymmetry, also called square face, however, symptoms such as trismus, protrusion and bruxism may also occur. The goals of the present investigation were: to report a case of idiopathic masseter hypertrophy, describe its symptoms and treatment. The patient reported bilateral bulging in the region of the mandible angle, of slow and progressive evolution. He did not complain of pain or discomfort, however there was bilateral otalgia, nighttime trismus and stress. In his physical exam we noticed bilateral masseter hypertrophy without local inflammatory alterations. We indicated surgical treatment with an extraoral approach. Complementary tests are indicated when there is diagnostic doubts. Treatment varies from conservative to surgical, and the later depends on surgeon skill and experience.

    Full Text Available A despeito do caráter benigno da endometriose, estima-se que 1% dos casos esteja relacionado com câncer, especialmente quando ambas as condições ocorrem nos ovários. Lesões extra-ovarianas encontradas no septo retovaginal, cólon, bexiga, vagina e peritônio da região pélvica também já foram associadas com neoplasias malignas. Várias características do tecido endometrial ectópico o aproximam do fenótipo neoplásico, e a própria endometriose possui comportamento tipicamente neoplásico com capacidade de invasão do estroma adjacente e associação com lesões à distância. Esta revisão atualiza conhecimentos diagnósticos, clínicos e terapêuticos dos implantes intestinais de tecido endometriótico, bem como sua relação com processos neoplásicos para melhor compreensão de seu caráter benigno ou de seu eventual potencial para malignidade.Endometriosis is generally assumed to be a benign disease, but it is estimated that 1% of cases are associated with cancer, especially when both conditions are present in the ovary. Extra-ovarian lesions in the rectovaginal septum, colon, bladder, vagina and peritoneum were already associated with malign neoplasia. Several characteristics of endometrial tissue are very similar to the neoplasia phenotype. Endometriosis itself typically behaves as a neoplasia process, spreading over adjacent stroma and being associated with distant lesions. This is an update on the diagnostic, clinical, and therapeutic knowledge of, management of bowel implants of endometrial tissue, as well as the relation with neoplastic processes to better understand its benign nature or eventual potential for malignancy.

    One extremely rare complication of chemotherapy for hematologic malignancies that is burdened with a high mortality rate (50%-80%) is necrotizing gastritis and gastric gangrene as result of poor clinical outcome of neutropenic gastritis (NG). We present a unique case of a neutropenic patient with necrotizing full thickness gastritis due to bacterial and fungal infection. Up to date only few such cases have been reported in world literature. A 28-year-old patient was subjected to dose-escalated BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone), (chemotherapy regimen) for Hodgkin lymphoma. In neutropenic patient abdominal pain, bleeding from the alimentary tract was observed. Hemorrhagic gastritis was recognized at endoscopy and CT demonstrated marked gastric wall thickness. Following NG diagnosis intensive treatment was initiated. On day 2 the patient's condition deteriorated (septic shock, multiple organ failure). Repeat endoscopy revealed gastric necrosis and laparotomy was performed. As consequence of cardiac arrest and cardiopulmonary resuscitation the surgical procedure was limited to total gastrectomy, feeding jejustomy and esophageal drainage through nasoesophageal catherization. Roux-loop esophagojejunostomy was performed on day 22 and supplemented 4 days later by endoscopic placement of covered self-expandable stent due to anastomosis leak. The procedure proved successful and oral feeding was well-tolerated. The patient was discharged in 32 days following recognition of gastric necrosis. Chemotherapy complications in neutropenic patients are life-threatening conditions. Immediate pharmacological treatment usually leads to improvement. Surgical management usually the resection of necrotic zones is restricted to cases of poor prognosis or deterioration of patient's condition and complications.

    Full Text Available Doxofylline is a methyl-xanthine with bronchodilator activity which clinical efficacy in the treatment of asthma and COPD is equivalent to theophylline. Clinical trials prooved that while doxofylline is as effective as theophylline in the treatment of asthma, it is associated with lesser side effects. For our pharmacoeconomical evaluation, we employed the data of an international multi-centric study that compared the efficacy and tolerability of 12 weeks of treatment with either theophylline 250 mg tid, or doxofylline 400 mg tid, or placebo. The efficacy was evaluated with pulmonary function tests and by recording the number of asthma attacks and beta-2 agonist puffs: doxofylline 1200 mg/day and theophylline 750 mg/day resulted equally effective, but the former resulted better tolerated, as the adverse effects were lesser in number and severity. We performed a cost/effectiveness analysis in order to compare the two treatments, considering the perspective of the Italian health system (SSN and of the Italian society. For the purposes of this analysis, the efficacy indices we considered were two: one simple, consisting in the number of avoided asthma attacks (AAA, and a more complex one, i.e. UATD (Utility Adjusted Therapy Days. For the construction of this index, we extracted the survival curve of the patients remaining in therapy; this curve showed that the cumulative number of therapy days is significantly greater in the doxofylline group, although the percentage of dropouts is similar at the end of the three months: this is due to the fact that the drop-outs in the theophylline group occur earlier after treatment start. The number of therapy days was then weighed for an utility index inversely proportional to the main daily number of avoided asthma attacks, thus obtaining the UATDs. The results of the cost/effectiveness analyses showed that doxofylline dominates theophylline treatment in asthma, as it is less expensive and more effective (in terms of AAAs and UATDs for both considered decision-makers, i.e. Italian SSN and society. The consistency of these results was further confirmed by oneway sensitivity analyses.

    In ulcerative colitis (UC), the main goals of treatment are to control disease activity and normalize health-related quality of life (HRQoL). In this study, we explored the relationship between disease activity (measured using the Simple Clinical Colitis Activity Index [SCCAI]) and patient HRQoL (measured using the EuroQoL [EQ]-5D-5L). A total of 199 patients with UC were followed for 6 months. At months 3 and 6, patients completed an online SCCAI. Within 2 days of completing the SCCAI, patients completed an at-clinic EQ-5D-5L questionnaire and the treating gastroenterologist completed the SCCAI. A consistent and approximately linear relationship was identified between patient HRQoL and patient-completed and physician-completed SCCAIs. A lower SCCAI score corresponded to a higher EQ-5D-5L index value. Correlation between EQ-5D-5L index values and patient-completed online SCCAIs was moderate (ρ -0.49; P UC. In line with the treat-to-target objective in UC, complete control of all symptoms is required to achieve optimal improvement in patient HRQoL. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Full Text Available Se estudiaron 60 pacientes menores de 15 años con estenosis esofágica, 40 de ellos por ingestión de cáusticos y 20 por otras causas, susceptibles de tratamiento de dilatación endoscópica. Esta se realizó bajo anestesia general con un endoscopio GIF-XP10 de la casa Olympus y bajo pantalla fluoroscópica con las bujías de Savary-Gilliard modelo pediátrico. En las estenosis esofágicas secundarias a ingestión de cáustico se asoció al tratamiento inyectoterapia endoscópica con betametasona. El 66,6 % de la serie fue por ingestión de cáustico y en segundo lugar las ocurridas por causas posquirúrgicas, para el 20 %. El 70 % de las poscáusticos se clasificó según radiografía como severo. La localización más frecuente de las estenosis fue el tercio superior del esófago, con predominio de la variedad tubular en las debidas a cáusticos, y la anular en las otras causas. En las poscáusticos se realizaron 919 dilataciones en 288 sesiones, mientras que en las originadas por otras causas se efectuaron 223 en 67 sesiones. Como complicación se reportan 8 perforaciones, 1 sepsis y 3 seudodivertículos en el grupo de los cáusticos. No se observó mortalidad. El grupo secundario a cáustico necesitó mayor número de sesiones y de dilataciones promedio con respecto al otro grupo y con el 47,5 % de curación y el 95 % en las de otras causas. Se demostró que el método de dilataciones esofágicas de Savary-Gilliard es seguro, eficaz y con un mínimo de complicaciones.60 patients under 15 with esophageal stenosis, 40 of them due to caustic ingestion and 20 by other causes, susceptible to the treatment of endoscopic dilatation, were studied. It was performed with general anesthesia, using an Olympus GIF-XP10 endoscope and under fluoroscopic screen with Savary-Gilliard bougies, pediatric model. In the esophageal stenoses secondary to caustic ingestion, endoscopic betamethasone injection therapy was associated with the treatment. 66.6 % of the series were caused by caustic ingestion, whereas 20 % were due to postsurgical causes. 70 % of the postcaustic ingestion group were classsified as severe according to X-rays. The most frequent localization of stenosis was the upper third of the esophagus with predominance of the tubular variety among those caused by caustic ingestion and of the annulate variety in the other causes. In the postcaustic ingestion group, 919 dilatations were carried out in 288 sessions, whereas 223 were performed in 67 sessions in those originated by other causes. 8 perforations, 1 sepsis and 3 pseudodiverticula were reported as complications in the group that ingested caustics. There was no mortality. Those who ingested caustics needed a higher average number of sessions and dilatations than the other group. 47.5 % of them were cured in this group, whereas 95 % healed in the other group. It was proved that Savary-Gilliard method of esophageal dilatations is safe, efficient and has a minimum of complications.

    Full Text Available A consecutive series of 21 patients with single limb atrophy (monomelic amyotrophy is reported. Sixteen had lower limb atrophy and five had upper limb involvement. The median age of the onset was 20 years. Characteristic features were sporadic occurrence, wasting confined to one limb, insidious onset with slow progression, stabilizing in 1 to 4 years, and absence of pyramidal signs. All the patients with upper limb involvement were male, however in our cases with lower limb amyotrophy there were no male preponderance. We observed wasting of the entire length of the lower limbs in six patients. There were nine cases with amyotrophy restricted to the leg and one with amyotrophy only in the thigh. In the upper limb in four cases the involvement was distal and in one patient the atrophy was proximal. The electromyographic features were suggestive of anterior horn disease not only in the affected limb but also, in some cases, in clinically uninvolved limb. Cervical or lumbar MRI was normal. MRI of the lower limb disclosed increased signal intensity in the gastrocnemius and soleus muscles in one patient suggesting denervation.Relatamos uma série consecutiva de 21 pacientes com amiotrofia de um só membro, denominada de amiotrofia monomélica. Em 16 casos a atrofia era no membro inferior e em 5 localizava-se no membro superior. Todos eram jovens e a idade média do início foi 20 anos. Os dados mais característicos da doença foram ausência de história familiar, comprometimento de um só membro, início e progressão lenta estabilizando em até 4 anos e ausência de sinais piramidais. Nossos enfermos com amiotrofia de membro superior eram todos do sexo masculino, entretanto naqueles com amiotrofia do membro inferior havia igualdade de sexos. Dos pacientes com atrofia de membro inferior, em 9 a atrofia era restrita a perna, em 6 era em todo o membro e somente um apresentava amiotrofia localizada só na coxa. Naqueles com comprometimento do membro superior a atrofia era distal em 4 e proximal em 1. Os achados na eletromiografia foram compatíveis com acometimento do II neurônio motor. Todos foram submetidos a RM da coluna cervical ou lombar que se mostrou normal. Em um caso realizamos RM da perna acometida que evidenciou sinais hiperintensos nos músculos gastrocnemius e soleus, o que sugere desnervação.

    Active chronic osteomyelitis or complicating osteomyelitis (superimposed on diseases that changes the normal bone structure fractures, post-surgery, prosthesis) can be difficult to diagnose by anatomic radiological imaging modalities, like plain radiograph and CT. These diseases frequently cause also increased bone remodeling, leading to nonspecific uptake of Tc-99m-bone scan agents and gallium-67. New radiopharmaceuticals with greater inflammation/infection avidity and specificity are being developed, including the nonspecific polyclonal immunoglobulin (IgG) labeled with technetium-99. Tc-99m-IgG may be available as a ready to use kit, with no reported side effects, low patient absorbed radiation dose and low cost. The mechanism of IgG uptake at the inflammation site has not been fully elucidated yet. Specific (receptor linking, physico-chemical immunoglobulin properties) and nonspecific mechanisms (enhanced vascular permeability and macromolecular exudate) has been suggested. IgG scintigraphy results are affected by the isotope, labeling procedure adopted and characteristics of the inflammatory focus. Nineteen patients with suspected osteomyelitis (active chronic osteomyelitis or violated bone osteomyelitis) were studied by Tc-99m-IgG scintigraphy (directly labeled polyclonal immunoglobulin, Sandoglobuilina - Sandoz). All patients also underwent standard three-phase bone scintigraphy using methylene diphosphonate (Tc-99m-MDP), gallium-67 scintigraphy and plain radiographs. Infection was found in 8 sites. Sensitivity and specificity for Tc-99m-MDP, gallium-67 and Tc 99m-IgG scintigraphy were, respectively, 88 and 36%, 75 and 73%,88 and 82%. All patients with false positive IgG scintigraphies had previous surgery. Other current scintigraphic procedures used in the diagnosis of osteomyelitis are also reviewed. (author)

    This research is an exploratory cross-sectional study about the relationship of chronic disease and the use of nuclear technology. There is a concern over the increase of the prevalence of chronic disease in developing countries and it should hence be carefully evaluated in the context of societies, organizations and individuals. The technological advances experienced in the last decades especially in the nuclear technology area have created expectations to deal more efficiently with the challenge of chronic diseases. However little has been explored in this area under the point-of-view of medical doctors as agents who make this system of relations between disease and technology. The necessity for public and private planning to deal with this set of problems can benefit through an initial evaluation about the forthcoming theme, but should incorporate the agenda of health and technology planning for the following years. Using mixed methodology, made up of qualitative and quantitative approach, this research sought to reveal and configure important dimensions around the theme of this study. The field research was made up of interviews analyzed using techniques of fundamental theory and also of questionnaires sent by web analyzed statistically using exploratory factor analysis. These ventures allowed dimensions to be revealed that make up the perception of chronic disease and the use of nuclear technology. These dimensions presented in a form of a theoretical construct that were then discussed under the point of view of social theory and technological innovation. (author)

    New e-health technologies can improve patient-physician communication and contribute to optimal patient care. We compared the diagnostic performance of the Simple Clinical Colitis Activity Index (SCCAI) self-administered by patients with ulcerative colitis (UC) at home (through a website) with the in-clinic gastroenterologist-assessed SCCAI. Patients were followed-up over 6 months. At months 3 and 6, patients completed the SCCAI online at home; within 48 h, gastroenterologists (blinded to patients' scores) completed the in-clinic SCCAI (reference). SCCAI scores were dichotomized to remission or active disease, and SCCAI changes in disease activity from month 3 to 6 were classed as worsening, stability, or improvement. A total of 199 patients (median age: 38 years; 56% female) contributed with 340 pairs of questionnaires. Correlation of SCCAI scores by patients and physicians was good (Spearman's ρ=0.79), with 85% agreement for remission or activity (95% CI: 80.8-88.6, κ=0.66). The negative predictive value for active disease was 94.5% (91.4-96.6); the positive predictive value was 68.0% (58.8-69.2). Agreement between patient and physician was higher in the 168 month 6 pairs than in the 172 month 3 pairs of questionnaires (89.3% (83.6-93.1) vs. 80.8% (74.2-86.0), P=0.027). In patients with UC, SCCAI self-administration via an online tool resulted in a high percentage of agreement with evaluation by gastroenterologists, with a remarkably high negative predictive value for disease activity. Remote monitoring of UC patients is possible and might reduce hospital visits.

    Standard treatment for patients with primary glioblastoma (GBM) includes surgery, radiotherapy, and concomitant and adjuvant temozolomide (TMZ). Recent reports have demonstrated that TMZ-induced myelosuppression correlates with survival in patients with GBM. However, those results were evaluated before the 2016 revision of the World Health Organization classification. This study examined whether myelosuppression during concomitant TMZ phase correlates with prognosis in GBM, IDH-wildtype patients. We examined circulating blood cell counts in 50 patients with GBM, IDH-wildtype who received the standard treatment protocol between August 2005 and November 2015. We assessed relationships between rates of decrease in blood cells (white blood cells (WBC), neutrophils, lymphocytes, red blood cells, and platelets) during the concomitant TMZ phase and overall survival (OS) using univariate and multivariate analyses including other clinicopathological factors (age, sex, Karnofsky Performance Status (KPS), extent of resection, O 6 -methylguanine-DNA methyltransferase (MGMT) status). Log-rank testing revealed that age, KPS, extent of resection, MGMT status, and decrease rates of WBC, neutrophils, and platelets correlated significantly with OS. On multivariate analysis, age, MGMT status, and decrease rate of neutrophils correlated significantly with OS. Patients with a ≥ 40% decrease in neutrophils showed significantly longer OS than those with IDH-wildtype. Blood cell counts during the concomitant TMZ phase can help predict OS in patients with GBM, IDH-wildtype receiving the standard treatment protocol.

    Full Text Available We report a 72-year-old male with known myelodysplastic syndrome who presented to the emergency department with a 7-day history of fever and dyspnea. Echocardiography revealed a round echogenic mass 13×16 mm in size attached to the atrial side of the tricuspid valve. Considering the high risk of infective endocarditis in the patient with a low absolute neutrophil count (130/mm3, emergency surgery was performed. Intraoperatively, a single gelatinous neoplasm was resected, and subsequent reconstruction of the involved leaflet was accomplished using autologous pericardium. The tumor was pathologically confirmed as papillary fibroelastoma with no evidence of infective endocarditis. Papillary fibroelastoma is a rare cardiac neoplasm that occurs in either the mitral or aortic valves. Interestingly, a few cases of tricuspid valve papillary fibroelastoma have been reported so far. Similar echocardiographic findings between vegetation and tricuspid valve neoplasm make it difficult to distinguish these two disease entities.

    The authors studied 15 cases of external hydrocephalus over a 7-year period (September 1987 to May 1995). External hydrocephalus is a condition in which infants with rapidly enlarging heads are found to have a MRI showing widening of subarachnoid space with mild or no ventricular dilatation. Some of the MRI were compared with those of patients with cerebral atrophy and some etiopathogenic hypothesis are presented. These findings indicate that external hydrocephalus is an age-related self-limited condition occurring in infants with open cranial sutures and that it usually resolves without intervention after the second or third year of age.

    Full Text Available Wicket spikes (WS are a benign eletroencephalogram (EEG variant, seen mainly in adults, during somnolence, in the temporal regions, in many clinical situations. WS can appear in trains or isolatedly, sometimes being difficult to differentiate from epileptiform activity. We reviewed 2,000 EEG's, found 65 with WS (3.25% and compared them with 65 normal EEG without WS. There was statistically significant (SS association between WS and age over 33; adolescent age was correlated to absence of WS and age over 65, to the presence of WS; there was an inverse correlation between WS and epilepsy, related to differences in age; a SS association with cerebrovascular disorders disappeared after controlling for age; a SS correlation with headache was also related to age; female predominance was not SS. There was a great variety of clinical situation associated with WS. We conclude that WS are a inespecific normal variant of the EEG that is age-related.As Wicket spikes (WS são um padrão benigno, variante da normalidade do eletrencefalograma (EEG, vistas principalmente em adultos, durante a sonolência, nas regiões temporais, em situações clínicas variadas.

    To examine the impact of research design on results in two published comparative effectiveness studies. Guidelines for comparative effectiveness research have recommended incorporating disease process in study design. Based on the recommendations, we develop a checklist of considerations and apply the checklist in review of two published studies on comparative effectiveness of colony-stimulating factors. Both studies used similar administrative claims data, but different methods, which resulted in directionally different estimates. Major design differences between the two studies include: whether the timing of intervention in disease process was identified and whether study cohort and outcome assessment period were defined based on this temporal relationship. Disease process and timing of intervention should be incorporated into the design of comparative effectiveness studies.

  14. Monitoring procalcitonin in febrile neutropenia: what is its utility for initial diagnosis of infection and reassessment in persistent fever?

    Directory of Open Access Journals (Sweden)

    James Owen Robinson

    Full Text Available BACKGROUND: Management of febrile neutropenic episodes (FE is challenged by lacking microbiological and clinical documentation of infection. We aimed at evaluating the utility of monitoring blood procalcitonin (PCT in FE for initial diagnosis of infection and reassessment in persistent fever. METHODS: PCT kinetics was prospectively monitored in 194 consecutive FE (1771 blood samples: 65 microbiologically documented infections (MDI, 33.5%; 49 due to non-coagulase-negative staphylococci, non-CNS, 68 clinically documented infections (CDI, 35%; 39 deep-seated, and 61 fever of unexplained origin (FUO, 31.5%. RESULTS: At fever onset median PCT was 190 pg/mL (range 30-26'800, without significant difference among MDI, CDI and FUO. PCT peak occurred on day 2 after onset of fever: non-CNS-MDI/deep-seated-CDI (656, 80-86350 vs. FUO (205, 33-771; p500 pg/mL distinguished non-CNS-MDI/deep-seated-CDI from FUO with 56% sensitivity and 90% specificity. PCT was >500 pg/ml in only 10% of FUO (688, 570-771. A PCT peak >500 pg/mL (1196, 524-11950 occurred beyond 3 days of persistent fever in 17/21 (81% invasive fungal diseases (IFD. This late PCT peak identified IFD with 81% sensitivity and 57% specificity and preceded diagnosis according to EORTC-MSG criteria in 41% of cases. In IFD responding to therapy, median days to PCT <500 pg/mL and defervescence were 5 (1-23 vs. 10 (3-22; p = 0.026, respectively. CONCLUSION: While procalcitonin is not useful for diagnosis of infection at onset of neutropenic fever, it may help to distinguish a minority of potentially severe infections among FUOs on day 2 after onset of fever. In persistent fever monitoring procalcitonin contributes to early diagnosis and follow-up of invasive mycoses.

    To asses the role of color duplex Doppler ultrasound (CDU) in the preoperative study of patients with varicose veins in lower extremities. We employed CDU to examine varicose veins in 342 lower limbs, assessing reflux in saphenous veins (SV), deep venous system (DVS) and perforating veins (PV). We analyzed the relationship between the anatomical extent of the reflux and the clinical findings. Insufficiency of the superficial venous system alone was uncommon, occurring in only 10.8% of the limbs examined. Reflux was observed in SV and PV in 48.2% of the legs. It was detected in all three systems in 29.2% of cases. The presence of reflux in more than one system and more than one value was associated with increased clinical severity. The site of venous reflux in lower extremities with varicose veins varies. Greater clinical severity is observed in the presence of more marked reflux in the DVS and PV. CDU provides anatomic and functional data on the three venous systems of the lower limbs, allowing an individualized therapeutic surgery. Preoperative localization of incompetent PV by means of CDU facilities their ligation. CDU is the technique of choice for the preoperative examination of the venous systems of patients with varicose veins. (Author)

    The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

    In this work, trace elements were analyzed in serum of patients with chronic myelogenous leukemia (CML) by Total Reflection X-Ray Fluorescence using synchrotron radiation (SRTXRF). Chronic myelogenous leukemia (CML) affects the myeloid cells in the blood and affects 1 to 2 people per 100,000 and accounts for 7-20% cases of leukemia. Sixty patients with CML and sixty healthy volunteers (control group) were studied. Blood was collected into vacutainers without additives. Directly after collection, each blood sample was centrifuged at 3000 rev/min for 10 min in order to separate blood cells and suspended particles from blood serum. Sera were transferred into polyethylene tubes and stored in a freezer at 253 K. A 500 {sup m}u{sup L} serum quantity was spiked with Ga (50 {sup m}u{sup L} ) as internal standard. 10 {sup m}u{sup L} aliquots were pipetted on Perspex sample carrier. After deposition, the samples were left to dry under an infrared lamp. The measurements were performed at the X-Ray Fluorescence Beamline at Brazilian National Synchrotron Light Laboratory (LNLS), using a polychromatic beam. Standard solutions with gallium as internal standard were prepared for calibration system. It was possible to determine the concentrations of the following elements: P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Br and Rb. Starting from the ANOVA test was observed that the elements P, S, Ca, Cr, Mn, Fe, Cu and Rb presented real significant differences ({alpha} = 0.05) between groups (healthy subjects and CML patients) and Sex (males and females).

    Full Text Available The aim of the paper is to compare healthcare-related costs of a 5-day course with fludarabine phosphate i.v. vs a 5-day course with oral fludarabine phosphate in Italian patients with chronic leukemia. A cost-minimization analysis was performed from both Italian National Healthcare Service (INHS and hospital perspectives. Healthcare-related costs were collected from 2 out of a sample of 28 Ematology wards and included those of drug acquisition, drug preparation, drug administration, reception and discharge of patient before and after drug administration; hospital overheads were calculated as a percentage of the total healthcare-related costs. The reimbursement schemes for acquisition and administration of fludarabine phosphate i.v. were gathered from the whole sample of 28 Ematology wards taken into account. Costs were expressed in euros 2004. When compared to fludarabine phosphate i.v., oral fludarabine phosphate allowed savings ranging from 223,47 euros (hospital perspective to 477,05 euros (INHS perspective per patient. As far as hospital perspective was concerned, savings associated with oral fludarabine phosphate were due to hospital overheads (115.1%, drug preparation (19.6%, drug administration (17.3%, reception and discharge of patient before and after drug administration (2.9%, whereas costs for drug acquisition was higher for oral formulation (-54.8%. When INHS perspective was taken into account, 3 out of 28 Ematology wards (11% were reimbursed on a drug-plus-outpatient-drug-administration-basis, whereas 25 out of 28 Ematology wards (89% were reimbursed on a day-hospital-stay-basis. Savings associated with oral fludarabine phosphate were due to day-hospital stay (253.4%, outpatient drug administration (1.1%, whereas cost for drug acquisition were higher for oral formulation (-154.5%. Sensitivity analysis confirmed the robustness of basecase results. Savings associated with oral fludarabine phosphate may be of relevant interest for INHS policies aimed at reducing public expenditure for drugs in Italy.

    Full Text Available OBJETIVO: Avaliar se a repetição de manobras de Epley em uma mesma sessão resulta em um menor número de sessões para abolir o nistagmo de posicionamento do que uma única manobra por sessão. MÉTODO: A manobra de Epley foi realizada em 123 pacientes com VPPB unilateral por ductolitíase do canal posterior. O grupo I foi composto por 75 pacientes submetidos a uma única manobra de Epley por sessão semanal e o grupo II foi constituído por 48 pacientes submetidos a quatro manobras na primeira sessão. RESULTADOS: O grupo II apresentou latência e duração do nistagmo maiores do que o grupo I (pAIM: To assess whether more than one Epley’s maneuver in the same session, compared to a single one, decreases the number of sessions necessary to suppress positional nystagmus. METHOS: Epley’s maneuver was done in 123 patients with BPPV due to unilateral posterior semicircular canal canalolithiasis. The number of sessions for positional nystagmus suppression was compared in two groups of patients. Group I consisted of 75 patients submitted to a single Epley’s maneuver on weekly sessions and group II consisted of 48 patients that were submitted to four Epley’s maneuvers during the first session. RESULTS: Group II showed greater nystagmus latency and duration than group I (p<0.05. The number of sessions and standard deviation showed by group I was greater than in group II (p=0.008. We observed a significant association between number of sessions and group (p=0.039 studied. Group II had 21.4% more nystagmus-free patients following only one session (CI95% [7.7% - 35.1%]. CONCLUSION: Repeated Epley’s maneuvers in less sessions rendered more positional nystagmus-free patients when compared to those submitted to more sessions of single maneuvers.

    In the paper six cases of facial osteomyelitis as a complication of chronic sinusitis in hemophiliac-AIDS patients are reported. Osteomyelitis was suggested by an increasing of erythrocyte sedimentation rate. The diagnosis was confirmed by a positive {sup 99m} Tc MDP scintigraphy. The patients were submitted to clinical treatment. The erythrocyte sedimentation rate and 67-gallium citrate scans were used in the follow-up of the therapy. Three patients had negative gallium after three weeks of organism-specific antibiotic therapy; in two patients the gallium scintigraphy remained positive. One patient did not undergo the radionuclide scan for this clinical conditions. These results suggest that MDP scans showed higher sensitivity and specificity in detection of bone disease in chronic sinusitis. Gallium scans appeared to be valuable tool in the follow-up of the infection. There are no reports in the literature of osteomyelitis as a complication of chronic sinusitis in AIDS patient.

    The eventual relation between biliary lithiasis and chronic pancreatitis (CP) has been studied before but the research on the gallbladder involvement in chronic pancreatitis patients are rare, specially from a functional point of view. In order to study that, gallbladder emptying was evaluated in 11 patients with CP and the results were compared and analyzed statistically with the ones observed in 10 controls. This series exclude patients and controls who presented any kind of prior or current affection, or condition, that could interfere with the gastric or gallbladder emptying and the release of the entero pancreatic hormones. Gallbladder emptying was studied through the scintillographic method, using Tc-99m DISIDA, through the calculation of the ejection (EF) of the gallbladder (GB), at 30, 45 and 60 minutes. In the patients this evaluation was studied in two different periods of time with an interval of two to four weeks between them, without (CPWOP) and with (CPWP) the addition of pancreatic extract. The analyses of the results disclosed that the EF of GB at 60 minutes was significantly higher in the controls when compared tro chronic pancreatopaths. On the other hand, the EF of GB in these patients did not show any statistically significant differences after the administration of pancreatic extract. The results suggest that the delay in the gallbladder emptying does not depend exclusively on the eventual alteration in the intestinal phase of the gallbladder stimulation, but it probably also results from the association with other factors involved, as a mechanic factor, which depends on the compression of the main biliary tract through the chronic pathological process located in the cephalic portion of the pancreas.

    To show the most outstanding findings from the chronic scrotal pathology of adults and boys, determining the benefits of the Doppler echography in the diagnostical valuation of the different cases analysed. 40 patients (19 adults and 21 boys) with chronic scrotal symptomatology were examined using a B mode echography followed by a colour duplex-Doppler (CDD) echography with a lineal 7.5 MHz transducer. We compared the findings obtained with those corresponding to the contralateral testicle and, depending on the pathology, we co-related them with surgery, pathologic anatomy or clinical-echograph evolution. The pathology found was very varied, it was distributed into: varicoceles (12), testicle tumours (9), extra-testicle tumours (4) and miscellaneous pathology (13). Two patients showed no changes, currently remaining asymptomatic. The treatment was surgical in 28 (70%) of the patients and traditional in the others. The B mode echography played a fundamental role in the diagnosis of chronic scrotal pathology, which in the majority of the cases was definitive, being completed with the application of the Doppler echograph to analyse the vascular condition of the lesions and the anatomical structures. The diagnosis utility of the CDD echograph in chronic scrotal pathology is controversial, it is not specific for testicle tumors, it is very useful for variocele and complementary, tp the B mode echograph for miscellaneous pathology.

    Full text. In order to evaluate the profile of the sex steroids gonadotropin and prolactin in polycystic ovarian syndrome (POS), 24 patients with POS were studied and compared with 20 normal women during the early follicular phase of the menstrual cycle. Radioimmunoassay techniques for androstenedione (A) and estrone (E{sub 1}) were standardized for the purpose of the study. Androstenedione and estrone were extracted from plasma with ethyl ether. The assays were maintained in equilibrium and the labelled hormone-antibody complex was then separated from the free hormone using dextran charcoal. The sensitivity of the method was 6.8 pg/tube for A and 3.7 pg/tube for E{sub 1}. Nonspecific binding ws 3.4 for A and 3.3 for E{sub 1}. The interessay error at the D50 level was 15.6 for A and 8.6 for E{sub 1}. Patients with POS had significantly higher basal levels of LH, A, T E{sub 1} and PRL and similar FSH and DHEA-S levels when compared with normal women. The LH/FSH ratio was significantly elevated and the A/T ratio was significantly decreased. The A/E{sub 1} and T/E{sub 2} ratios were elevated and the E{sub 1}/E{sub 2} was decreased, although the differences were not statistically significant. A positive correlation between A and E{sub 1} was observed in patients with POS. In view of the above data, it was concluded that: the quality control parameters of the radioimmunoassay for A and E{sub 1} standardized in the present study are considered satisfactory, and the assay could be used for diagnosis and research; the patients with POS have a different sex steroid and gonadotropin profile when compared normal women during the early follicular phase of the menstrual cycle

    The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the left axilla. An ultrasound guided fine needle biopsy of this lymph node identified by I-131 SPECT/CT and FDG-F-18 PET/CT revealed lymphoma cells and was negative for thyroid tissue and thyroglobulin content. The sequential blood counts done routinely after radiation treatment showed a marked fall until return to normal values of leucocytes and lymphocytes (absolute and relative), which were still normal in the last control 19 months after the radioiodine administration. Chest computed tomography showed a decrease in size of axillary and paraaortic lymph nodes. By immunohistochemistry, cells of the lymphoid B lineage decreased from 52% before radioiodine therapy to 5% after the procedure. The authors speculate about a possible sodium iodide symporter expression by the cells of this lymphoma, similar to some other non-thyroid tumors, such as breast cancer cells. (author)

    The casiopeinas are a family of coordination compounds with copper metallic center that have shown to have antineoplastic activity. The experimental evidences suggest that its action mechanism is through the generation of free radicals. The casiopeina (Cas II-gly) is believed to causes oxidative damage in the mitochondria, leading to the cellular death. The present study has the purpose to evaluate the antioxidant potential of the tetrapyrroles: cupro-sodica chlorophyllin (CSC), protoporphyrin-Ix (Pp-Ix) and the bilirubin (Bili) against the oxidant action of the Cas II-gly. The present study will also contribute in the characterization of the biological activity of the Cas II-gly. For this purpose is quantifies the effect of these compounds in the enzymes activity, superoxide dismutase (Sod) and catalase (Cat) in wild Drosophila melanogaster strains Canton-S and in the deficient in Sod and Cat. Two protocols were used, in the first male of 1-24 h of age were pre-treated with 0, 0.01, 0.1 and 1 m M of Cas II-gly and later on they were treated with radiation (15 Gy), and the second 69 m M of CSC, Pp-Ix or Bili, during 8 days and later they were treated with 0.1 m M of Cas II-gly during 24 h. The enzymatic activity was measured with the detection packages of enzymes Sod and Cat of Sigma. It was found that none of the three pigments increment the Sod activity but, if they diminished that of Cat (p≤0.007). The three concentrations of Cas II-gly did not increase the Sod activity significantly, only the concentration of 0.1 m M diminishes in 5.6 U the Cat activity (p <0.03) the same as the treatment with 15 Gy of gamma rays (8 U, p <0.004). The Cas II-gly combination 0.1 m M with the pigments does not modify the Sod and Cat activity. These results suggest that the proven pigments act as antioxidants, avoiding the induction of exogenous antioxidants caused by the gamma rays or the Cas II-gly. (Author)

    Full Text Available BACKGROUND: Mirizzi syndrome is a rare complication of prolonged cholelithiasis, characterized by narrowing of the common hepatic duct due to mechanical compression and/or inflammation due to biliary calculus impacted in the infundibula of the gallbladder or in the cystic duct. OBJECTIVES: To describe a series of eight consecutive patients with Mirizzi syndrome, at a single institution, submitted to surgical treatment and to comment on their aspects with emphasis on the diagnosis and treatment. METHODS: Four women and four men, with a mean age of 61.6 years (42 to 82 years, presenting Mirizzi syndrome were operated between 1997 and 2003. The following items were evaluated: clinical presentation, laboratory results, preoperative evaluation, operative findings, presence of choledocholithiasis, type of Mirizzi syndrome according to the classification by Csendes, choice of operative procedures, and complications. RESULTS: The most frequent symptoms were abdominal pain (87.5% and jaundice (87.5%. All the patients presented altered hepatic function tests. The diagnosis of Mirizzi syndrome was intra-operative in seven (87.5% patients, and preoperative in one (12.5%. Cholecystocholedochal fistula associated with choledocholithiasis was observed in three (37.5% cases. Mirizzi syndrome was classified as Csendes type I in five (62.5% patients, type II in one (12.5%, type III in one (12,5% and type IV in another (12.5%. Cholecystectomy, as an isolated surgical procedure, was performed in four (50.0% patients. One (12.5% patient was submitted to partial cholecystectomy and closure of the fistulous orifice with the central part of the infundibula. Two (25.0% patients were submitted to cholecystectomy and side-to-side choledochoduodenostomy and another (12.5% to side-to-side choledochoduodenostomy remaining the gallbladder in situ. Seven (87.5% patients had an uneventful recovery and were discharged in good conditions. One (12.5% patient presented a postoperative sepsis due to a sub-hepatic abscess, and was reoperated. There was no operative mortality. CONCLUSION: The preoperative diagnosis of Mirizzi syndrome is difficult and an awarded suspicion is necessary to avoid lesions of the biliary tree. The problem may only become evident during the operation due to firm adherences around Calot's triangle. The success of the treatment is related to a precocious recognition of the condition, even at the time of surgery, and adapting the management considering to the individual characteristics of each case.RACIONAL: A síndrome de Mirizzi, é complicação rara da colelitíase de longa duração, caracterizada pelo estreitamento do ducto hepático comum devido a mecanismo de compressão e/ou inflamação por cálculos biliares impactados no infundíbulo da vesícula biliar ou no ducto cístico. OBJETIVO: Descrever série de oito enfermos consecutivos com síndrome de Mirizzi de uma única instituição, submetidos ao tratamento cirúrgico e comentar seus aspectos com ênfase no diagnóstico e tratamento. MÉTODO: Quatro mulheres e quatro homens, com média de idade de 61,6 anos (42 a 82 anos, foram operados com síndrome de Mirizzi entre 1997 e 2003. Avaliaram-se a apresentação clínica, os resultados dos exames laboratoriais e de imagem, os achados operatórios, a presença de coledocolitíase, o tipo de síndrome de Mirizzi de acordo com a classificação de Csendes, a escolha do procedimento operatório e as complicações pós-operatórias. RESULTADOS: Os sintomas mais freqüentes foram dor abdominal (87,5% e icterícia (87,5%. Todos os doentes apresentaram exames de função hepática alterados. O diagnóstico da síndrome de Mirizzi foi intra-operatório em sete (87,5% doentes, e pré-operatório em um (12,5%. Observou-se fístula colecistocoledociana associada à coledocolitíase em três (37,5% casos. A síndrome de Mirizzi foi classificada como tipo I em cinco (71,4% doentes, tipo II em um (14,3%, tipo III em um (12,5%, e tipo IV em outro (12,5%. A colecistectomia, como procedimento cirúrgico isolado, foi realizada em quatro (50,0% doentes. Um (12,5% enfermo foi submetido a colecistectomia parcial e fechamento do orifício fistuloso com a região central do infundíbulo. Dois (25,0% enfermos foram submetidos a colecistectomia e anastomose coledocoduodenal látero-lateral e outro (12,5% a anastomose coledocoduodenal látero-lateral, deixando-se a vesícula biliar in situ. Sete (87,5% doentes evoluíram sem complicações pós-operatórias e obtiveram alta hospitalar em boas condições. Um (12,5% enfermo apresentou, no pós-operatório, sepse por abscesso sub-hepático, sendo re-operado. Não houve mortalidade operatória. CONCLUSÕES: O diagnóstico pré-operatório da síndrome de Mirizzi é difícil e é necessário elevado índice de suspeita para evitar lesões da árvore biliar. O problema pode se tornar evidente apenas no momento da operação na forma de aderências firmes ao redor do triângulo de Calot. O sucesso do tratamento está relacionado ao reconhecimento precoce da condição, mesmo no intra-operatório, e na individualização da conduta, de acordo com as características de cada caso.

    Full Text Available Bacteremia remains a major cause of life-threatening complications in patients receiving anticancer chemotherapy. The spectrum and susceptibility profiles of causative microorganisms differ with time and place. Data from Lebanon are scarce. We aim at evaluating the epidemiology of bacteremia in cancer patients in a university hospital in Lebanon, emphasizing antibiotic resistance and risk factors of multi-drug resistant organism (MDRO-associated bacteremia.This is a retrospective study of 75 episodes of bacteremia occurring in febrile neutropenic patients admitted to the hematology-oncology unit at Makassed General Hospital, Lebanon, from October 2009-January 2012.It corresponds to epidemiological data on bacteremia episodes in febrile neutropenic cancer patients including antimicrobial resistance and identification of risk factors associated with third generation cephalosporin resistance (3GCR and MDRO-associated bacteremia. Out of 75 bacteremias, 42.7% were gram-positive (GP, and 57.3% were gram-negative (GN. GP bacteremias were mostly due to methicillin-resistant coagulase negative staphylococci (28% of total bacteremias and 66% of GP bacteremias. Among the GN bacteremias, Escherichia coli (22.7% of total, 39.5% of GN organisms and Klebsiellapneumoniae(13.3% of total, 23.3% of GN organisms were the most important causative agents. GN bacteremia due to 3GC sensitive (3GCS bacteria represented 28% of total bacteremias, while 29% were due to 3GCR bacteria and 9% were due to carbapenem-resistant organisms. There was a significant correlation between bacteremia with MDRO and subsequent intubation, sepsis and mortality. Among potential risk factors, only broad spectrum antibiotic intake >4 days before bacteremia was found to be statistically significant for acquisition of 3GCR bacteria.

    Full Text Available Solo il 15-20% dei pazienti con epatite C cronica presenta una risposta virologica protratta dopo terapia con solo interferon (IFN. Lo scopo di questo studio è di confrontare l’efficacia e la sicurezza dell’IFN in combinazione con ciclosporina A (CsA orale con l’IFN in monoterapia nel trattamento dell’epatite C cronica. 120 pazienti affetti da epatite C cronica hanno ricevuto la dose standard Giapponese di IFN a2b da solo per 24 settimane o questa dose di IFN a2b in combinazione con CsA, alla dose di 200 mg/die per le prime 4 settimane e poi di 100 mg/die per altre 20 settimane. In tutti i pazienti sono stati valutati la sicurezza, l’efficacia e la tolleranza alla fine delle settimane 4, 12, 24 e 48. L’efficacia è stata valutata mediante la scomparsa dei livelli sierici del genoma di HCV (RNA-HCV ricercato con reazione polimerasica a catena (PCR, e la normalizzazione delle transaminasi. L’end point primario era il mantenimento della risposta virologica; cioè il mantenimento di RNA-HCV a livelli sierici indosabili fino alla 48esima settimana. Il grado di mantenimento della risposta virologica è stata significativamente più alto nel gruppo con terapia combinata, IFN-CsA, rispetto al gruppo con IFN in monoterapia (p = 0.01. Il grado di mantenimento della risposta biochimica era più alto nel gruppo con terapia combinata rispetto a quello con monoterapia (p = 0.017. Nei pazienti con genotipo virale 1 di HCV ed alta carica virale, il grado di mantenimento della risposta virologica era marcatamente più alto nel gruppo con terapia combinata rispetto al gruppo con IFN in monoterapia (p = 0.006. Il profilo di effetti collaterali era simile nei due gruppi. In pazienti con epatite C cronica il trattamento combinato IFNCsA è più efficace rispetto alla monoterapia con IFN, soprattutto nei pazienti con genotipo virale 1 di HCV ed alta viremia. Altri studi in vitro hanno recentemente dimostrato che la CsA, a differenza di altri

    Full Text Available Il trattamento del morbo di Crohn con infliximab rappresenta una importante terapia nei pazienti con la forma fistolizzata della malattia, refrattaria al trattamento con farmaci convenzionali. Tuttavia esistono preoccupazioni nell’usare questo farmaco in pazienti con concomitante infezione cronica da HCV. Tali preoccupazioni sono determinate dal rischio teorico di un accelerato scompenso epatico dovuto all’effetto immunomodulante dell’Infliximab. Noi descriviamo il caso di un paziente affetto da morbo di Crohn e concomitante infezione attiva da epatite C sottoposto a terapia con Infliximab che non ha mostrato alcun peggioramento della funzionalità epatica e dei livelli di carica virale testati con PCR.

    2014-04-01

    A 67-year-old woman known to have iron deficiency anemia and persistent unexplained chronic leukopenia was cared for by our medical center for about 16 years. During this period she was examined thoroughly and diagnosed to have chronic idiopathic neutropenia (also known as chronic benign neutropenia). Her iron deficiency was attributed to nutritional factors and she was non-compliant with her oral iron supplements. The patient fully received her iron supplement medication by nursing staff for two and a half months during an unexpected prolonged hospital stay after her suffering an acute ischemic cerebrovascular accident. An astonishing outcome was that in addition to having her iron deficiency anemia treated, her long-term unexplained neutropenia was also corrected. Some patients diagnosed with chronic idiopathic neutropenia and clinically present as having unexplained chronic neutropenia might actually be suffering from a form of not yet described iron deficiency induced neutropenia.

    The major dose-limiting toxicity associated with myelosuppressive chemotherapy is neutropenia, which can be ameliorated with proactive administration of granulocyte colony-stimulating factor (G-CSF). Pegfilgrastim is a long-acting G-CSF, recently approved by the Food and Drug Administration. The efficacy and safety of pegfilgrastim administered once/chemotherapy cycle have been evaluated in clinical trials involving patients treated with myelosuppressive chemotherapy for breast cancer, lung cancer, non-Hodgkin's lymphoma, and Hodgkin's disease. Two pivotal phase III trials in patients with breast cancer showed that pegfilgrastim is as effective as filgrastim regarding the primary efficacy end point, which was duration of grade 4 (severe) neutropenia in cycle 1 of myelosuppressive chemotherapy. Secondary end points were the frequency of fever with neutropenia (febrile neutropenia), duration of neutropenia in cycles 2-4, depth of the absolute neutrophil count (ANC) nadir, and time to ANC recovery in cycles 1-4. Once/cycle pegfilgrastim 100 microg/kg or 6 mg was as safe and effective as daily filgrastim 5 microg/kg in reducing the frequency and duration of severe neutropenia. A trend toward a greater reduction in the overall frequency of febrile neutropenia with pegfilgrastim was observed. The availability of pegfilgrastim simplifies the use of prophylactic G-CSF, with the potential to increase patient convenience and adherence in management of chemotherapy-induced neutropenia.

    Patients with end-stage renal disease who develop hypersplenism, patients with mild neutropenia, and those patients whose WBC fails to increase in response to cortisol administration will develop significant neutropenia following transplantation with routine doses of azathioprine. This "intolerance" of azathioprine mandates a reduction in the dose of azathioprine often resulting in allograft rejection. Splenectomy will prevent azathioprine-induced neutropenia, but the hazards of splenectomy in these immunosuppressed patients have led to attempts to salvage at least part of the spleen. Partial splenic ablation by embolization has been utilized in adults prior to transplantation to prevent azathioprine-induced neutropenia while preserving the spleen's protective mechanisms against infection. Eight children in our series of transplant candidates required a reduction of splenic function to prevent azathioprine induced neutropenia. One child had a functioning renal allograft but had recurrent neutropenia limiting the azathioprine dose. Partial splenic embolization was attempted in four children and was initially successful in two. Both patients later developed recurrent neutropenia and needed partial splenectomy. The two patients in whom partial splenic embolization was unsuccessful and five further patients in whom embolization was not attempted also underwent partial splenectomy. Approximately 75% to 80% of the spleen was resected. Six children have since undergone renal transplantation and one child had a transplant with chronic rejection at the time of partial splenectomy. Routine doses of azathioprine have been used in these children with no episodes of neutropenia or sepsis observed. We recommend partial splenectomy in those children requiring renal transplantation who are at risk for development of azathioprine induced neutropenia.

    Full Text Available Pseudomonas aeruginosa is an extremely dangerous cause of sepsis in patients with antitumor chemotherapyassociated neutropenia. Sometimes, the source of infection may be localized lesions of the skin (e.g. folliculitis or its derivatives, which are not of particular concern in the absence of neutropenia. The appearance of Ecthyma gangrenosum in a patient with neutropenia, even in the absence of any signs or symptoms of sepsis, requires emergency care and the appointment of antibiotics with high antipseudomonal activity. We are report the case of the complications of chemotherapy with the sequential development of Ecthyma gangrenosum and Pseudomonas aeruginosa septicemia in a patient with concomitant skin infection (folliculitis.

    Full Text Available During the period of neutropenia due to chemotherapy, patients have high risk of infections. The use of antibiotic prophylaxis to reduce neutropenia-related complications in oncologic patients is still disputed. Recent meta-analysis and clinical trials demonstrated that antibiotic prophylaxis with chinolons reduces fever episodes, bacterial infections and mortality in adult oncologic patients with neutropenia due to chemotherapy for acute leukaemia. In paediatric patients, the only randomized, double-blind, prospective study up till now suggested that Amoxicillin clavulanate may represent an effective prophylactic treatment to reduce fever and infections in oncologic children with neutropenia, with an efficacy statistically demonstrated only in patients with acute leukaemia. Considering the risk of resistances, antibiotic-prophylaxis should be used only in selected patients.

    The granulocyte associated IgG in normal and neutropenic subjects has been determined by a direct quantitative assay using radiolabeled staphylococcal protein A. This assay allows to postulate an immunological mechanism to explain the neutropenia in 19 cases of neutropenias associated with malfunctions of the immune system and in 4 cases of idiopathic neutropenias. Discussed in this report is the possible interaction of immune complexes bound in vivo to the granulocytes. By an immunofluorescence test, it has been possible to detect IgG or IgM antibodies in only 52% of patients with a positive direct assay. The determination of granulocyte-associated IgG is therefore a better indicator for defining an auto-immune neutropenia than the detection of free antibodies in the sera [fr

    Full Text Available Background: Haematopoietic stem cell transplantation is a curative treatment option for many haematological disorders. Infection following haematopoietic stem cell transplantation is one of the major causes of mortality. Aims: To investigate the outcomes of early cessation of empirical antibiotic treatment per protocol in febrile neutropenia patients who have undergone haematopoietic stem cell transplantation at our clinic. Study Design: Descriptive study. Methods: The present study retrospectively evaluated febrile neutropenia attacks in haematopoietic stem cell transplantation recipients during the period June 2014 - January 2015 at our haematopoietic stem cell transplantation clinic. Results: A total of 72 febrile neutropenia attacks were evaluated in 53 patients. In 46 febrile neutropenia attacks, microbiologic cultures revealed positive results. In culture-positive febrile neutropenia episodes a single bacterium was isolated in 32 cases and multiple strains were isolated in 14. In 15 patients, empirical antibiotic therapy was discontinued after 72 hours. These patients were clinically stable, without evident focus of infection and had negative culture results. Only 4 recurrent episodes were observed (27% after cessation of antibiotherapy. No patient died as a result of recurrent infection. The 30-day and 100-day post-transplantation mortality rates of patients with febrile neutropenia episodes were 11.3% (6/53 and 3.8% (2/53, respectively. Infection-related 30-day and 100-day mortality rates were 7.5% (4/53 and 0% (0/53, respectively. Conclusion: The main message of our study is that early cessation of empirical antibiotherapy seems to be feasible in eligible patients without increasing febrile neutropenia mortality rates

    Despite long-term clinical experience with docetaxel, unpredictable severe adverse reactions remain an important determinant for limiting the use of the drug. To identify a genetic factor(s) determining the risk of docetaxel-induced leukopenia/neutropenia, we selected subjects who received docetaxel chemotherapy from samples recruited at BioBank Japan, and conducted a case-control association study. We genotyped 84 patients, 28 patients with grade 3 or 4 leukopenia/neutropenia, and 56 with no toxicity (patients with grade 1 or 2 were excluded), for a total of 79 single nucleotide polymorphisms (SNPs) in seven genes possibly involved in the metabolism or transport of this drug: CYP3A4, CYP3A5, ABCB1, ABCC2, SLCO1B3, NR1I2, and NR1I3. Since one SNP in ABCB1, four SNPs in ABCC2, four SNPs in SLCO1B3, and one SNP in NR1I2 showed a possible association with the grade 3 leukopenia/neutropenia (P-value of leukopenia/neutropenia, and 18 with no toxicity. The combined analysis indicated a significant association of rs12762549 in ABCC2 (P = 0.00022) and rs11045585 in SLCO1B3 (P = 0.00017) with docetaxel-induced leukopenia/neutropenia. When patients were classified into three groups by the scoring system based on the genotypes of these two SNPs, patients with a score of 1 or 2 were shown to have a significantly higher risk of docetaxel-induced leukopenia/neutropenia as compared to those with a score of 0 (P = 0.0000057; odds ratio [OR], 7.00; 95% CI [confidence interval], 2.95-16.59). This prediction system correctly classified 69.2% of severe leukopenia/neutropenia and 75.7% of non-leukopenia/neutropenia into the respective categories, indicating that SNPs in ABCC2 and SLCO1B3 may predict the risk of leukopenia/neutropenia induced by docetaxel chemotherapy.

    The aim of this study was to evaluate the efficacy and feasibility of intensified consolidation therapy employing fludarabine and ARA-C in cycle 1 and intermediate-dose ARA-C (IDAC) in cycles 2 through 4, in elderly acute myeloid leukemia (AML) patients and to analyze the effects of pegfilgrastim on the duration of neutropenia, overall toxicity, and hospitalization-time during consolidation in these patients. Thirty nine elderly patients with de novo AML (median age 69.9 years) who achieved complete remission (CR) after induction-chemotherapy were analyzed. To examine the effect of pegfilgrastim on neutropenia and hospitalization, we compared cycles 2 and 4 where pegfilgrastim was given routinely from day 6 (IDAC-P) with cycle 3 where pegfilgrastim was only administered in case of severe infections and/or prolonged neutropenia. All four planned cycles were administered in 23/39 patients (59.0%); 5/39 patients (12.8%) received 3 cycles, 3/39 (7.7%) 2 cycles, and 8/39 (20.5%) one consolidation-cycle. The median duration of severe neutropenia was 7 days in cycle 2 (IDAC-P), 11.5 days in cycle 3 (IDAC), and 7.5 days in cycle 4 (IDAC-P) (P consolidation can be administered in AML patients ≥60, and those who are consolidation shortens the time of neutropenia and hospitalization in these patients. © 2017 Wiley Periodicals, Inc.

    This is the case of a child aged 11 months with a history of systemic sepsis from Pseudomona aeruginosa at 5 months, neutropenia, leucopenia, sepsis-associated anemia and from then, recurrent acute respiratory infections of the high respiratory tract, allergic manifestations and furunculosis from pseudomona. Immunologic study conducted showed a decreased figure of IgG with a light increase of CD4 +c ooperative-IgM of T cells. Also, we found the presence of neutropenia and marked defect of phagocytosis. We made the diagnosis of granulocyte-associate congenital hypogammaglobulinemia. The patient was treated with human gamma globulin by intramuscular route, transference factor and immunoferon, with an obvious improvement

    Three UK bred Border collie puppies were presented for investigation of pyrexia and severe lameness with associated joint swelling. Investigations revealed neutropenia, radiographic findings suggesting metaphyseal osteopathy, and polyarthritis and all dogs were subsequently confirmed with trapped neutrophil syndrome. Clinical improvement was seen after treatment with prednisolone and antibiotics and the dogs all survived to adulthood with a good short- to medium-term outcome. Trapped neutrophil syndrome is an important differential diagnosis for young Border collie dogs in the UK presenting with pyrexia, neutropenia and musculoskeletal signs. © 2013 British Small Animal Veterinary Association.

    20 lactating ewes were allotted to two groups: 10 subjects received orally 100 mg/day of CdCl{sub 2} for 108 consecutive days, and the remaining 10 acted as control. Reproductive performance in ewes and cadmium tissue accumulation, both in ewes and their lambs, were investigated. The results showed that in ewes: 1) the regular cadmium intestinal intake negatively influences all reproductive parameters; 2) cadmium is particularly accumulated in kidney and liver, bur also in mammary gland, although at distinctly lower level; 3) chronic administration does not increase cadmium placental transfer in lactating pregnant subjects. [Italian] 20 pecore in lattazione sono state suddivise in 2 gruppi: 10 soggetti ricevettero per os 100 mg/giorno di CdCl{sub 2} per 108 giorni consecutivi, e i restanti 10 funsero da controllo. Sono stati studiati i parametri riproduttivi delle pecore e l'accumulo di cadmio nei tessuti, sia delle pecore che dei loro agnelli. I risultati hanno mostrato che negli ovini: 1) il regolare assorbimento intestinale di cadmio influenza negativamente tutti i parametri riproduttivi; 2) il cadmio viene accumulato principalmente nei reni e nel fegato, ma anche dalla ghiandola mammaria, sebbene in misura nettamente inferiore; 3) la somministrazione cronica di cadmio nei soggetti gravidi non incrementa il suo passaggio transplacentare.

    Full Text Available In this review paper schistosomal glomerulopathy is defined as an immune-complex disease. The disease appears in 12-15 per cent of the individuals with hepatosplenic schistosomiasis. Portal hypertension with collateral circulation helps the by pass of the hepatic clearance process and the parasite antigens can bind to antibodies in the circulation and be trapped in the renal glomerulus. Chronic membranousproliferative glomerulonephritis is the most commom lesion present and the nephrotic syndrome is the usual form of clinical presentation. The disease can be experimentally produced, and schistosomal antigens and antibodies, as well as complement, can be demonstrated in the glomerular lesions. Specific treatment of schistosomiasis does not seem to alter the clinical course of schistosomal nephropathy.A glomerulopatia esquistossomotica e um exemplo de doenca causada por complexos imunes.

    Riassunto Alcuni virus possono essere trasmessi verticalmente da madre a figlio in seguito allo sviluppo, da parte della madre, di un’infezione primaria, ricorrente o cronica. La trasmissione materno-fetale dei virus, che può avvenire in utero (infezione congenita), durante il travaglio del parto (infezione perinatale), oppure attraverso l’allattamento (infezione postnatale), può causare aborto spontaneo, morte fetale, ritardo di crescita intrauterino, anomalie congenite e patologie neonatali o postnatali di diversa entità. Alcuni fattori di rischio sembrano influenzare l’incidenza di trasmissione materno-fetale dei virus, come ad esempio la presenza di altre infezioni virali, la carica virale materna, il tipo di infezione (primaria o ricorrente), la durata della rottura delle membrane, la modalità con cui avviene il parto, le condizioni socio-economiche e l’allattamento. Oggi è possibile prevenire la trasmissione materno-fetale di molti virus grazie all’utilizzo di vaccini, immunizzazione passiva e farmaci antivirali. Il rischio di trasmissione delle infezioni perinatali e postnatali, inoltre, può essere diminuito evitando l’allattamento o ricorrendo ad un parto cesareo. PMID:19216201

No es asi con la intoxicación aguda, puesto que sus signos y síntomas son reversibles. Presentamos un paciente con convulsiones parciales complejas, secundarias a un quiste temporal, que habia sido tratado irregularmente con DFH durante dos años con dosis variables que oscilaban en los 100 mg/dia. Dada la refractariedad de su cuadro convulsivo en una entrevista previa a su ingreso se le indico un aumento brusco de la dosis del fármaco que alcanzo a los 400 mg/dia. Ello ocasiono un sindrome pancerebeloso severo que motivo su internación. Posteriormente a la suspension de la DFH y la exeresis del quiste temporal mejoro su cuadro convulsivo, aunque quedo con ataxia de miembros inferiores y asinergia de tronco, cuadro con el que fue dado de alta. Un año despues, el paciente se encontraba libre de convulsiones, pero su sindrome cerebeloso no se habia modificado. El estudio por imágenes no evidencio atrofia cerebelosa.

    2010-11-01

    The monoclonal anti-CD20 antibody Rituximab (RTX) is increasingly used in allogeneic stem cell transplantation (SCT) to treat lymphoproliferative disorders and chronic graft-versus-host disease (GVHD). RTX administration can be complicated by delayed and prolonged neutropenia, but the mechanism is unclear. We report the occurrence of profound cytopenias following RTX given in the conditioning regimen or early after T cell-deplete SCT to treat B cell lymphoproliferative disorders or chronic GVHD (cGVHD). Between 2006 and 2009, 102 patients (median age: 43 years, range: 13-68 years), received a myeloablative matched-sibling T cell-deplete SCT for lymphoid or myeloid hematologic disorders. Neutropenia occurring within 4 weeks of treatment developed in 16 of 17 patients given RTX within the first 190 days after SCT. Fourteen patients developed severe neutropenia (count SCT compared to patients with cGVHD not treated with early RTX (P SCT experienced only moderate neutropenia 3 to 5 months after treatment lasting 10 to 20 days while maintaining absolute neutrophil count (ANC) >1.0 × 10⁹/L. Although RTX rapidly controlled cGVHD, we conclude that its administration early after T cell-deplete SCT is associated with prolonged profound and life-threatening cytopenias, and should be avoided.

To evalute the incidence and severity of leukopenia and neutropenia among liver recipients treated with VGC and related factors. Retrospective analysis of clinical and analytical data related to leukopenia (leukopenia developed. In the induced neutropenia group, previous leukocyte count (3797.1 +/- 1223.9 vs 5683.9 +/- 2829.3; P = .01), MELD (18.7 +/- 8.8 vs 11.1 +/- 6.6; P = .01), and the creatinine pretreatment (1.44 +/- 0.4 vs 1.09 +/- 0.3; P = .01) were significantly different. Subsequent infections induced by the leukopenia were not observed. In our series, the concomitant use of VGC and MMF was not associated with a greater incidence of leukopenia and/or neutropenia than VGC administration alone. Previous leukocyte count was associated with them. MELD and renal dysfunction are factors related to severe neutropenia. Leukopenia was not associated with a greater incidence of infections.

    Full Text Available BACKGROUND: Azathioprine (AZA, used to treat inflammatory bowel disease (IBD, is metabolized by thiopurine methyltransferase (TPMT. The accumulation of individual metabolites varies because humans display genetic polymorphism for TPMT expression. Deficiencies in TPMT result in accumulation of toxic metabolites, followed by neutropenia and hepatic inflammation. Concern over acute toxicity frequently leads to under dosing and frequent monitoring tests and visits.

    The aim of this study was to assess changes in body composition during neoadjuvant chemotherapy (NAC) and investigate whether chemotherapy-related toxicities affect body composition in patients with esophageal cancer. In ninety-four patients who underwent NAC for esophageal cancer, body composition was assessed before and after NAC. Associations between the incidence of toxicities and change in body composition during NAC were investigated. Forty-four (46.8%) and 50 (53.2%) out of 94 patients were defined as having sarcopenia before and after NAC, respectively. There was no significant difference in the incidence of any toxicity pre-treatment between patients with sarcopenia and those without sarcopenia. No significant reduction in skeletal muscle mass or fat mass was observed in the patients during NAC (p=0.501 and p=0.072). However, patients who experienced grade 4 neutropenia or febrile neutropenia during NAC showed a significantly larger decrease in change of skeletal muscle mass compared to patients who did not experience those toxicities (p=0.013 and 0.036, respectively). The incidence of serious adverse events such as febrile neutropenia and grade 4 neutropenia is associated with a significant reduction of skeletal muscle mass during NAC. We should make an effort to reduce the incidence of adverse events in order to maintain an appropriate body composition during NAC.

    To gain a better understanding of the impact of dose and other prognostic factors on safety and efficacy of docetaxel in second-line non-small-cell lung cancer patients. A model-based meta-analysis (MBMA) of a published docetaxel monotherapy data in 6085 second-line non-small-cell lung cancer patients from 46 trials was conducted. The logit of grade 3/4 neutropenia incidence was a linear function of dose, with a 5% increase in the odds of neutropenia per mg/m(2) increase in dose [odds ratio (OR) 1.05, 95% confidence interval (CI) 1.04-1.06], and a Japanese study effect (OR 17.1, 95% CI 6.05-48.4). The logit of overall response rate (ORR) was a linear function of cumulative dose (0.4% increase in the odds of response per mg/m(2) increase; OR 1.004, 95% CI 1.001-1.008) and median population age (OR 1.08 per year, 95% CI 1.02-1.15). A Japanese study effect was identified for overall survival (OS) in addition to prognostic factors identified by a previous meta-analysis. This current MBMA identified docetaxel dose-response relationships for both neutropenia and ORR, an effect of age on ORR, and Japanese study effects on both neutropenia and OS.
