Incidencia de la infección por el virus de la hepatitis A diagnosticadas en la ciudad de Maracaibo estado Zulia Venezuela / Incidence of infection by the hepatitis A virus diagnosed in the city of Maracaibo state Zulia Venezuela

La infección por el virus de la hepatitis A (VHA) sigue siendo un problema de salud pública en los países en vías de desarrollo. El objetivo de la presente investigación fue determinar la incidencia de la infección por el VHA en individuos de la ciudad de Maracaibo, estado Zulia, Venezuela. Durante el periodo comprendido entre enero 2004 a diciembre 2007 se seleccionaron 1056 pacientes en edades de 1 a 60 años de ambos sexos (media ± DS: 27,48 ± 5,24), procedentes de los municipio Maracaibo y San Francisco ubicados en la ciudad de Maracaibo estado Zulia, Venezuela. La presencia de anticuerpos anti-IgM contra el virus de la hepatitis A se determinó mediante métodos convencionales de micro partículas enzimoinmunoanalisis (MEIA). Los resultados encontrados indican una seropositividad en 73 (35,1%), 76 (28%), 66 (24,3%), 35 (20,3%) individuos de las zonas Norte, Sur, Este, Oeste respectivamente, correspondientes al municipio Maracaibo y 31 (23,3%) correspondiente al municipio San Francisco. La mayor prevalencia fue observada en pacientes del sexo femenino menor de 20 años (47,3%), y en pacientes del sexo masculino menor de 10 años (53,7%), siendo el signo clínico más frecuente la ictericia (95,7%). Las deficientes medidas de saneamiento ambiental y sanitario fueron factores aparentemente determinantes en la diseminación del VHA

Hepatitis A virus (HAV) infection continues to be a public health problem in developing countries. The aim of this study was to determine incidence of the hepatitis A virus infection in a population from Maracaibo, Venezuela. From January, 2004 until December, 2007, this study was carried out on 1056 individuals, whose ages were between 1-60 years (average ± DS: 27.48 ± 5.24 years), coming from the Maracaibo and San Francisco municipalities, Venezuela. The IgM antibody against HAV was determined by the ELISA technique. The overall incidence was 26.6%. The North, South, East and West areas of the Maracaibo Municipality and the San Francisco Municipality in the city of Maracaibo showed incidences of 73 (35.1%), 76 (28%), 66 (24.3%), 35 (20.3%) and 31 (23.3%), respectively. The highest incidences were observed in females under 20 years (47.3%) and males under 10 years (53.7%). The most frequent clinical sign was jaundice in 95.7% of patients. Deficient sanitary conditions and hygiene habits seemed to be the main risk factors in spreading HAV infection

Spectrum of primary immune deficiency at a tertiary care hospital.

OBJECTIVE: To report various primary immune deficiencies diagnosed in children at a tertiary care hospital, their clinical manifestations and laboratory profile. METHODS: Case records of children diagnosed to have primary immunodeficiency disorders over a period of 24 months at a tertiary care hospital in northern India were evaluated. RESULTS: Twenty-seven children (M: F=3.5: 1) with mean age of 5.4 +/- 4.6 yrs (2 mo-16 yr) were diagnosed to have primary immunodeficiency. Thirteen children had chronic granulomatous disease (CGD), 4 had severe combined immunodeficiency (SCID), 4 had hypogammaglobulinemia, 2 had Ataxia telangiectasia, and one each had DiGeorge syndrome, Wiskott Aldrich syndrome, hyper IgM syndrome and leukocyte adhesion defect. Common mode of presentation were recurrent/ persistent pneumonia in 19, recurrent/ persistent diarrhea in 10, deep seated abscesses in 8, allergy in 3, disseminated tuberculosis infection in 2, extensive fungal infections in 2 and 1 each of disseminated cytomegalovirus (CMV) infection, disseminated BCG disease, otitis media and meningitis. Family history of sibling deaths was elicited in 2 families. Infectious agents were isolated in 16 cases. CONCLUSION: From a single center 27 patients with primary immune deficiency could be identified by chart review, suggesting need for high index of suspicion for diagnosis of primary immune deficiency in India. Though the exact prevalence is not known there is need to make a registry to document the magnitude of problem of these disorders.
