ABSTRACT

SUMMARY: The therapeutic effect of a granulocyte-colony stimulating factor (G-CSF) biosimilar drug, zarzio, on non-alcoholic fatty liver disease (NAFLD) in a rat model was investigated in this study. Thirty-two rats were randomly divided into four groups. Groups I and II were fed a standard laboratory diet, whereas groups III and IV were fed a high fat diet (HFD) for 14 weeks. After 12 weeks of feeding, groups I and III were administered normal saline, and groups II and IV were intraperitoneally administered zarzio (200 mg/kg/day) for two consecutive weeks. Hematoxylin-eosin (H&E) staining was used to assess hepatic and pancreatic morphology in all groups, oil red O (ORO) staining for lipid accumulation, Masson's staining for fibrosis, and immunohistochemistry assay for hepatic protein expression of insulin receptor substrate 1 (IRS1), nuclear factor erythroid 2-related factor 2 (Nrf2), tumour necrosis factor alpha (TNF-α) and pancreatic caspase-3. The NAFLD rats (group III) developed hepatic steatosis with increased lipid accumulation, perisinusoidal fibrosis, upregulated IRS1, TNF-α (all P<0.05) without a significant increase in Nrf2 protein expression compared with normal control. In comparison, model rats treated with zarzio (group IV) showed significant rejuvenation of the hepatic architecture, reduction of fat accumulation, and fibrosis. This was accompanied by the upregulation of Nrf2, downregulation of IRS1 and TNF-α protein expression (all P<0.05). No correlation was detected between NAFLD and non-alcoholic fatty pancreas disease (NAFPD). However, the pancreatic β-cells in group III showed increased caspase-3 expression, which was decreased (P<0.05) in group IV. In conclusion, zarzio ameliorates NAFLD by improving the antioxidant capacity of liver cells, reducing hepatic IRS1, TNF-α protein expression and pancreatic β-cells apoptosis, suggesting that zarzio could be used as a potential therapy for NAFLD.


En este estudio se investigó el efecto terapéutico de un fármaco biosimilar del factor estimulante de colonias de granulocitos (G-CSF), zarzio, sobre la enfermedaddel hígado graso no alcohólico (NAFLD) en un modelo de rata. Treinta y dos ratas se dividieron aleatoriamente en cuatro grupos. Los grupos I y II fueron alimentados con una dieta estándar de laboratorio, mientras que los grupos III y IV fueron alimentados con una dieta alta en grasas (HFD) durante 14 semanas. Después de 12 semanas de alimentación, a los grupos I y III se les administró solución salina normal, y a los grupos II y IV se les administró zarzio por vía intraperitoneal (200 mg/kg/ día) durante dos semanas consecutivas. Se utilizó tinción de hematoxilina-eosina (H&E) para evaluar la morfología hepática y pancreática en todos los grupos, tinción con rojo aceite O (ORO) para la acumulación de lípidos, tinción de Masson para la fibrosis y ensayo de inmunohistoquímica para la expresión de la proteína hepática del sustrato 1 del receptor de insulina (IRS1), factor nuclear eritroide 2 relacionado con el factor 2 (Nrf2), factor de necrosis tumoral alfa (TNF-α) y caspasa-3 pancreática. Las ratas NAFLD (grupo III) desarrollaron esteatosis hepática con aumento de la acumulación de lípidos, fibrosis perisinusoidal, IRS1 y TNF-α regulados positivamente (todos P <0,05) sin un aumento significativo en la expresión de la proteína Nrf2 en comparación con el control normal. En comparación, las ratas modelo tratadas con zarzio (grupo IV) mostraron un rejuvenecimiento significativo de la arquitectura hepática, una reducción de la acumulación de grasa y fibrosis. Esto estuvo acompañado por la regulación positiva de Nrf2, la regulación negativa de la expresión de la proteína IRS1 y TNF-α (todas P <0,05). No se detectó correlación entre NAFLD y la enfermedad del páncreas graso no alcohólico (NAFPD). Sin embargo, las células β pancreáticas en el grupo III mostraron una mayor expresión de caspasa-3, que disminuyó (P <0,05) en el grupo IV. En conclusión, zarzio mejora la NAFLD al mejorar la capacidad antioxidante de las células hepáticas, reduciendo el IRS1 hepático, la expresión de la proteína TNF-α y la apoptosis de las células β pancreáticas, lo que sugiere que zarzio podría usarse como una terapia potencial para la NAFLD.

ABSTRACT

Background and aims: A dysfunctional immune response is key to the pathogenesis of acute-on-chronic liver failure (ACLF). It has been suggested that treatment with granulocyte colony-stimulating factor (G-CSF) increases survival in patients with ACLF by improving immune cell dysfunction and promoting liver regeneration. The aim of the study is to evaluate the survival benefit associated with G-CSF administration compared with standard medical therapy (SMT) in ACLF. Methods: Systematic review and meta-analysis of randomized controlled trials. The primary outcome was survival at 60–90 days. We searched Ovid Medline, EMBASE, and Cochrane Central Register of Controlled Trials from inception to August 2021. Manual searches of reference lists in relevant articles and conference proceedings were also included. The revised Cochrane risk-of-bias tool was used for quality and risk of bias assessment. Two independent investigators extracted the data, and disagreements were solved by a third collaborator. Results: The initial search identified 142 studies. Four randomized controlled trials were selected for quantitative analysis including 310 patients (154 G-CSF and 156 SMT). Significant heterogeneity was observed (I2=74%, Chi2=11.57, p=0.009). G-CSF administration did not improve survival in patients with ACLF (random-effects model, risk ratio=0.64 [95% CI 0.39, 1.07]). However, when considering only the results from the studies performed in Asia, a significant decrease on mortality was observed (risk ratio=0.53 [95% CI 0.35, 0.81]). Severity scores (MELD and Child) and CD34+ peripheral cells mobilization did not significantly improve with G-CSF. Conclusion. In a systematic review and meta-analysis, G-CSF administration did not significantly improve overall survival compared to SMT in patients with ACLF...(AU)


Antecedentes y objetivos: La respuesta inmune disfuncional es clave en la patogénesis del fallo hepático agudo sobre crónico (ACLF). Se ha sugerido que la utilización de factor estimulante de colonias de granulocitos (G-CSF) aumenta la supervivencia de los pacientes con ACLF al mejorar la disfunción inmune y promover la regeneración hepática. El objetivo del estudio es evaluar el beneficio en supervivencia que proporciona la administración de G-CSF en comparación con el tratamiento médico estándar (SMT) en pacientes con ACLF. Métodos: Se llevó a cabo una revisión sistemática y meta-análisis de estudios aleatorizados y controlados. El objetivo principal fue analizar la supervivencia a los 60-90 días. Se realizó una búsqueda en Ovid Medline, EMBASE, y el registro central de estudios controlados de Cochrane desde su inicio hasta agosto 2021. También se realizaron búsquedas manuales en la bibliografía de artículos relevantes y presentaciones a congresos. Se utilizó la herramienta revisada de Cochrane para analizar la calidad y el riesgo de sesgos. Los datos fueron extraídos por dos investigadores independientes y las discrepancias fueron resueltas por un tercer investigador. Resultados: La búsqueda inicial identificó 142 estudios. De estos, 4 aleatorizados y controlados fueron elegidos para el análisis cuantitativo, incluyendo un total de 310 pacientes (154 G-CSF y 156 SMT). Se objetivó un alto grado de heterogeneidad entre los estudios (I2 = 74%, Chi 2 = 11.57, p = 0.009). La administración de G-CSF no aumentó la supervivencia en el grupo de pacientes con ACLF (modelo de efectos aleatorios, risk ratio = 0.64 [95% CI 0.39, 1.07]). Sin embargo, cuando se analizó el subgrupo de estudios realizados en Asia, sí se objetivó una disminución significativa de la mortalidad (risk ratio = 0.53 [95% CI 0.35, 0.81]). Las escalas de gravedad (MELD y Child) y la movilización de células CD34+ periféricas no mejoró significativamente tras la administración de G-CSF....(AU)

Severity scores (MELD and Child) and CD34+ peripheral cells mobilization did not significantly improve with G-CSF. CONCLUSION: In a systematic review and meta-analysis, G-CSF administration did not significantly improve overall survival compared to SMT in patients with ACLF. The beneficial effects observed in Asian studies, as opposed to the European region, suggest that specific populations may benefit from further research aiming to identify certain subgroups with favourable outcomes when using G-CSF.

ABSTRACT

La Proteinosis Alveolar Pulmonar (PAP) es una enfermedad poco frecuente, caracterizada por la acumulación de material lipoproteico derivado del surfactante pulmonar al interior de los alvéolos por una falla de depuración de este material por los macrófagos alveolares, siendo la causa más frecuente de esta disfunción la acción bloqueadora producida por anticuerpos anti factor estimulante de colonias de granulocitos y macrófagos (GM-CSF) lo que lleva a un deterioro del intercambio gaseoso. La evolución es variable abarcando desde la resolución espontánea hasta la insuficiencia respiratoria grave y la muerte. Se describen tres formas de PAP: Genética, secundaria y autoinmune (antes primaria o idiopática) siendo esta última la más frecuente en adultos. Clínicamente, se manifiesta por disnea, tos seca e hipoxemia que pueden ser progresivas. En la radiografía de tórax se encuentran opacidades bilaterales y la tomografía computarizada de tórax de alta resolución (TACAR) muestra vidrio esmerilado con sobre posición de engrosamiento septal intra e interlobulillar, patrón conocido como "crazy paving". El diagnóstico se basa en la clínica y en el lavado broncoalveolar con material PAS positivo. La biopsia quirúrgica es confirmatoria. El tratamiento clásico es el lavado pulmonar total (LPT) para remover el contenido alveolar. Otras alternativas son la administración de GM-CSF subcutáneo o inhalado, plasmaferesis y rituximab, cuyos resultados son variables. Diferentes autores han modificado la forma del LPT y combinado los diferentes métodos de tratamiento con el fin de obtener resultados más rápidos y efectivos.


Pulmonary Alveolar Proteinosis (PAP) is a rare disease characterized by the accumulation of surfactant derived lipoproteinaceous material filling the alveoli, secondary to failure of its clearance by macrophages. Most of the patients are adults that have auto antibodies directed to Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF). The evolution is towards disturbed gaseous exchange with a wide spectrum of disease from spontaneous recovery to death. There are three forms of PAP: genetic, secondary and autoimmune. Symptoms are scarce and patients may present with dyspnea, dry cough and hypoxemia. Chest X ray shows bilateral opacities and thorax CT depicts ground glass opacities surrounded by septal widening, the so called "crazy paving" pattern. Diagnosis is made on clinical and radiological grounds and confirmed by PAS positive staining of bronchoalveolar lavage material or surgical lung biopsy. Accepted treatment is whole lung lavage (WLL) with saline. Alternatives are subcutaneous or inhaled GM-CSF, Plasmapheresis or Rituximab, and even modification of the method of WLL and combination of different manner of treatment.

ABSTRACT

Introducción: La Neutropenia Febril es una complicación potencialmente fatal del tratamiento del cáncer, relacionada con mayor morbilidad, mortalidad, disminución de dosis o retardo en los ciclos de quimioterapia, y resultados finales pobres. Estudios anteriores han demostrado el beneficio de Factor Estimulante de Colonias de Granulocitos en la reducción de tiempo de hospitalización, antibióticos intravenosos, fiebre y recuperación del conteo absoluto de neutrófilos. Se decide realizar el presente reporte ya que no existen datos respecto al manejo y respuesta al tratamiento en nuestro medio. Métodos: El presente estudio descriptivo, retrospectivo, fue realizado en el Instituto del Cáncer SOLCA ­ Cuenca. Se revisaron las historias clínicas del período 2010 ­ 2011. Las variables analizadas fueron: número de días de hospitalización, fiebre, uso de antibióticos intravenosos, y días de recuperación de neutropenia a >500/mm3 y >1000/mm3. Resultados: La estancia hospitalaria tuvo una mediana de 6 días, los días de terapia antibiótica intravenosa fueron iguales a los días de hospitalización. 79 eventos se recuperaron a un conteo absoluto de neutrófilos >500/mm3, en una mediana de 4 días; 72 eventos se recuperaron a >1000 /mm3 en una mediana de 4 días. La mayoría de los eventos se volvieron afebriles en una mediana de 1 día. Conclusión: Los resultados de las variables estancia hospitalaria, uso de antibióticos intravenosos y la duración de la fiebre fueron similares a los ya descritos en estudios anteriores, la recuperación del conteo absoluto de neutrófilos, fue más tardía, mostrando diferencias importantes con la bibliografía.


Introduction: Febrile Neutropenia is a potentially fatal complication of cancer treatment, related to higher morbidity, mortality, dose reduction or retard in chemotherapy cycles, and poor final outcomes. Previous studies have demonstrated the benefit of G-CSF (Granulocyte ­ Colony Stimulating Factors) in reduction of hospital stay, the use of intravenous antibiotics, fever and absolute neutrophil count (ANC) recovery. There is no data about the management and treatment response in our population. Methods: This is a retrospective descriptive study, developed in SOLCA ­ Cuenca Cancer Institute. 83 febrile neutropenia events met the inclusion and exclusion criteria, medical records from years 2010 to 2011 were reviewed. The analyzed variables were: days of hospital stay, fever, intravenous antibiotics use, and neutropenia recovery to a level >500/mm3 and >1000/mm3. Results: The median of hospital stay was 6 days, the duration of IV antibiotic therapy was the same as the days of hospital stay. 79 events recovered to an ANC >500/mm3, with a median of 4 days; 72 events recovered to >1000 /mm3 with a median of 4 days. The majority of events became afebrile with a median of 1 day. Conclusion: The results in the variables hospital stay, use of intravenous antibiotics and fever duration, were similar to those described in previous studies. The ANC recovery was delayed, showing important differences with cited references.

ABSTRACT

Introducción: en Cuba la recolección de células madre autólogas se realizaba mediante punción de las crestas ilíacas. Para ello se requería anestesiar al paciente y disponer de un quirófano con el personal capacitado y entrenado en la técnica. La introducción de un método simplificado permitió extender el proceso a todas las provincias del país.Objetivo: analizar información actualizada sobre el proceso de movilización y el método manual para la recolección y procesamiento de las células mononucleares de la médula ósea.Método: se revisó la literatura nacional e internacional sobre el tema en los últimos 12 años, en español e inglés y en formatos impreso y digital. La búsqueda en Internet abarcó varias bases de datos y el buscador Google Académico. A partir de los materiales seleccionados se elaboró una reseña estructurada. Desarrollo: las diferentes modalidades de trasplante de células madre hematopoyéticas surgieron como alternativa terapéutica ante los efectos adversos de las altas dosis de quimioterapia y radioterapia en pacientes oncológicos. Sin embargo, mediante el trasplante autólogo de células madre hematopoyéticas es posible administrar al paciente dosis farmacológicas intensas con una toxicidad hematopoyética y orgánica tolerable. Conclusiones: los conocimientos actuales sobre el proceso de movilización celular, y el método manual para la recolección y procesamiento de las células mononucleares de la médula ósea, abren posibilidades alentadoras en la investigación básica y clínica. Las propiedades exclusivas de estas células y la sencillez de su procesamiento posibilitan su utilización en el tratamiento de diferentes enfermedades(AU)


Introduction: in Cuba the collection of autologous stem cells was performed by puncture of the iliac crests. To do this, it was necessary to anesthetize the patient and have an operating room with qualified personnel trained in the technique. The introduction of a simplified method allowed extending the process to all the provinces of the country.Objective: to analize updated information about the mobilization process and the manual method for the collection and processing of the bone marrow mononuclear cells.Method: the national and international literature on the subject was reviewed in the last 12 years, in Spanish and English, and in printed and digital formats. The search on the Internet covered several databases and the Google Scholar search engine. A structured review was prepared from the selected materials.Development: the different modalities of hematopoietic stem cell transplantation emerged as a therapeutic alternative to the adverse effects of high doses of chemotherapy and radiotherapy in cancer patients. However, through autologous hematopoietic stem cell transplantation, it is possible to administer intense pharmacological doses to the patient with tolerable hematopoietic and organic toxicity.Conclusions: the knowledge of the processes of self-renewal and differentiation of the stem cells, the methods to mobilize them to the peripheral blood, collect them and process them for their therapeutic use, opens up encouraging possibilities in basic and clinical research. The exclusive properties of these cells make possible their use in the treatment of different diseases(AU)

ABSTRACT

INTRODUCTION AND OBJECTIVE: To improve the complete remission (CR) rate of newly diagnosed acute myeloid leukemia (AML) patients and alleviate the severe side effects of double induction chemotherapy, we combined a standard regimen with granulocyte colony-stimulating factor (G-CSF) priming chemotherapy to compose a new double induction regimen for AML patients who failed to achieve CR after the first course. PATIENTS AND METHODS: Ninety-seven patients with AML who did not achieve CR after the first course of standard chemotherapy were enrolled. Among them, 45 patients received G-CSF priming combined with low-dose chemotherapy during days 20-22 of the first course of chemotherapy, serving as priming group, 52 patients were administered standard chemotherapy again, serving as control group. RESULTS: Between the two groups there were no differences in the French-American-British (FAB) classification, risk status, the first course of chemotherapy, blood cell count or blasts percentage of bone marrow before the second course. But the CR rate was significantly higher and the adverse effect was much lower in the priming group than the control group. Cox multivariate regression analysis showed that WBC level before the second course and the selection of the second chemotherapy regimen were two independent factors for long survival of patients. DISCUSSION: These results elucidate that standard chemotherapy followed by G-CSF priming new double induction chemotherapy is an effective method for AML patients to improve CR rate and reduce adverse effects.

ABSTRACT

Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the accumulation of surfactant-like lipoproteinaceous material in the distal air spaces and terminal bronchi, which may lead to impaired gas exchange. This accumulation of surfactant is due to decreased clearance by the alveolar macrophages. Its primary, most common form, is currently considered an autoimmune disease. Better knowledge of the causes of PAP have led to the emergence of alternatives to whole lung lavage, although this is still considered the treatment of choice. Most studies are case series, often with limited patient numbers, so the level of evidence is low. Since the severity of presentation and clinical course are variable, not all patients will require treatment. Due to the low level of evidence, some objective criteria based on expert opinion have been arbitrarily proposed in an attempt to define in which patients it is best to initiate treatment.

ABSTRACT

Se realizó un estudio descriptivo, transversal y prospectivo de 201 pacientes con cáncer de mama atendidos en el Servicio de Quimioterapia del Hospital Oncológico Docente Provincial Conrado Benítez García de Santiago de Cuba durante un año (de junio del 2013 a igual mes del 2014), a fin de caracterizarles y determinar la presencia de neutropenia como reacción adversa al tratamiento. La información fue analizada estadísticamente mediante el cálculo porcentual y la prueba de la Χ2, con lo cual se obtuvo que 82 pacientes padecieran neutropenia (40,7 por ciento), en quienes predominó el grupo etario de 41-60 años (50,0 por ciento), el estadio clínico II del tumor maligno (65,8 por ciento) y un único episodio de neutropenia (90,2 por ciento). En cuanto a las pacientes diagnosticadas con neutropenia, se registraron 91 episodios, con mayor frecuencia de los grados moderado (52,7 por ciento) y leve (39,5 por ciento), y una reacción favorable al factor estimulante de colonias de granulocitos humano en 81,8 por ciento de ellas. Por último, se demostró la existencia de neutropenia como efecto adverso a los citostáticos en casi 50 por ciento de las pacientes, así como el resultado beneficioso del factor estimulante en estas; sin embargo, no se halló asociación entre las diferentes combinaciones de citostáticos y los episodios y grados de neutropenia(AU)


A descriptive, cross-sectional and prospective study of 201 patients with breast cancer assisted in the Chemotherapy Service of Conrado Benítez García Teaching Provincial Oncological Hospital in Santiago de Cuba was carried out during a year (from June, 2013 to the same month of 2014), in order to characterize them and to determine neutropenia as adverse reaction to the treatment. The information was analyzed statistically by means of the percentage calculation and the test Chi squared test, with which it was obtained that 82 patients suffered neutropenia (40.7 percent) in whom the age group 41- 60 years prevailed (50.0 percent), the clinical stage II of the malignant tumor (65.8 percent) and just one neutropenia episode (90.2 percent). As for the patients diagnosed with neutropenia, 91 episodes were registered, with higher frequency of the moderated degrees (52.7 percent) and mild (39.5 percent), and a favorable reaction to the stimulating factor of human granulocytes colonies 81.8 percent of them. Lastly, the neutropenia existence as adverse effect to the cytostatic drugs in almost 50 percent of the patients was demonstrated, as well as the beneficial result of the stimulating factor in them; however, there was no association between the different combinations of cytostatic drugs and the episodes and neutropenia degrees(AU)

En cuanto a las pacientes diagnosticadas con neutropenia, se registraron 91 episodios, con mayor frecuencia de los grados moderado (52,7 %) y leve (39,5 %), y una reacción favorable al factor estimulante de colonias de granulocitos humano en 81,8 % de ellas. Por último, se demostró la existencia de neutropenia como efecto adverso a los citostáticos en casi 50 % de las pacientes, así como el resultado beneficioso del factor estimulante en estas; sin embargo, no se halló asociación entre las diferentes combinaciones de citostáticos y los episodios y grados de neutropenia.


A descriptive, cross-sectional and prospective study of 201 patients with breast cancer assisted in the Chemotherapy Service of "Conrado Benítez García" Teaching Provincial Oncological Hospital in Santiago de Cuba was carried out during a year (from June, 2013 to the same month of 2014), in order to characterize them and to determine neutropenia as adverse reaction to the treatment. The information was analyzed statistically by means of the percentage calculation and the test Chi squared test, with which it was obtained that 82 patients suffered neutropenia (40.7%) in whom the age group 41- 60 years prevailed (50.0%), the clinical stage II of the malignant tumor (65.8%) and just one neutropenia episode (90.2%). As for the patients diagnosed with neutropenia, 91 episodes were registered, with higher frequency of the moderated degrees (52.7%) and mild (39.5%), and a favorable reaction to the stimulating factor of human granulocytes colonies 81.8% of them. Lastly, the neutropenia existence as adverse effect to the cytostatic drugs in almost 50% of the patients was demonstrated, as well as the beneficial result of the stimulating factor in them; however, there was no association between the different combinations of cytostatic drugs and the episodes and neutropenia degrees.

ABSTRACT

Se efectuó un estudio descriptivo, longitudinal y prospectivo de 26 pacientes con cáncer en diferentes localizaciones asociado a leucopenia y neutropenia inducidas por citotóxicos, atendidos en el Servicio de Quimioterapia del Hospital Oncológico Docente Conrado Benítez de Santiago de Cuba, de mayo del 2011 a igual mes del 2012, con vistas a determinar el efecto del factor de colonias granulocítica recombinante Ior® LeukoCIM --producido por el Centro de Inmunología Molecular de Ciudad de La Habana-- en ellos mediante la realización de conteos globales de leucocitos y neutrófilos, antes y después de aplicar el tratamiento. En la serie predominaron el sexo femenino, el cáncer de mama y el estadio clínico II; también se obtuvo que 92,3 por ciento de los pacientes respondieron satisfactoriamente a la terapia, el estadio clínico del cáncer no modificó el efecto mielodepresor de los citotóxicos ni el mieloestimulador de la hormona, y el cisplatino y la adriamicina se relacionaron con las neutropenias mayores y la falta de reacción al factor. Para finalizar, el Ior® LeukoCIM estimuló el sistema granulopoyético de la mayoría de los afectados(AU)


A descriptive, longitudinal and prospective study was conducted in 26 patients with cancer in different locations associated with leukopenia and neutropenia induced by cytotoxic drugs, treated at the Chemotherapy Department of Conrado Benítez Teaching Oncology Hospital of Santiago de Cuba, from May 2011 to the same month of 2012, with the purpose of determining the effect of the recombinant granulocyte-colony factor Ior® LeukoCIM --produced by the Center of Molecular Immunology in Havana city-- in them by means of global counts of leukocytes and neutrophils before and after applying the treatment. Female sex, breast cancer and clinical stage II prevailed in the series. It was also found that 92.3 percent of patients responded successfully to the therapy, the clinical stage of cancer did not modify the myelosuppressive effect of cytotoxic drugs nor the myelostimulating effect of hormone, and cisplatin and adriamycin were related to higher neutropenia and lack of reaction to the factor. Finally, the Ior® LeukoCIM stimulated the granulopoietic system of most patients(AU)

ABSTRACT

La neutropenia es un motivo relativamente frecuente de referencia al Servicio de Inmunología y Reumatología Pediátrica del Hospital Nacional de Niños; el estudio pretende caracterizar los casos de neutropenia referidos a este Servicio en el periodo comprendido entre noviembre de 1988 y junio de 2008. Métodos: Se estudiaron 84 pacientes entre 0 y 12 años de edad, referidos entre el 6 de noviembre de 1988 y el 1 de junio de 2008. Se efectuó un análisis descriptivo global de las características presentadas por estos pacientes en términos de evolución clínica, patrón de infección, gérmenes más frecuentes causantes de infección, complicaciones y tratamiento. Resultados: El 52.2 por ciento de los pacientes analizados resolvieron su neutropenia espontáneamente, por lo que fueron catalogados como neutropenia transitoria; el 21.7 por ciento de los casos evolucionó como neutropenia cíclica; el 13 por ciento de los pacientes fueron catalogados como neutropenia crónica benigna; el 7.2 por ciento evolucionaron como neutropenia crónica grave sintomática; el 2.9 por ciento tuvieron neutropenia asociada a glucogenosis tipo 1B, y el 2.9 por ciento de los casos no fueron clasificables en las categorías propuestas. El 56.5 por ciento de los casos se asoció a un patrón de infección anormal, sea por un incremento enla frecuencia, mayor gravedad, compromiso multisistémico o presencia de microorganismos oportunistas. El sistema más afectado por infección fue la vía respiratoria superior...


Neutropenia is a relatively common cause of patient referral to the Immunology and Pediatric Rheumatology Department of the National Children’s Hospital. The present study characterizes the cases of neutropenia referred to this department between November 1988 andJune 2008. Methods: Eighty four patients between 0 and 12 years of age, were referred from November 6th, 1988 and June 1st, 2008. We performed a comprehensive descriptive analysis of the characteristics exhibited by these patients in terms of clinical course, pattern of infection, mostcommon causative germs, complications and treatment applied. Results: Neutropenia resolved spontaneously in 52.2% of the patients, and they were classified as transient neutropenia, 21.7% of the cases developed cyclic neutropenia, 13% of werecategorized as benign chronic neutropenia, 7.2% developed severe chronic symptomatic neutropenia, 2.9% had neutropenia associated with type 1B glycogenosis and 2.9% of the caseswere not classifiable in any of the proposed categories. More than 50% of the cases were associated with an abnormal pattern of infection in terms of frequency, severity, multiplicity ofsystems involved, or the presence of opportunistic microorganisms...
