Frecuencia y características de la encefalopatia hipertensiva secundaria a glomerulonefritis posinfecciosa en pacientes internados en un hospital de referencia nacional

Introducción: La glomerulonefritis aguda pos infecciosa (GNPI) puede cursar con complicaciones como la encefalopatía hipertensiva en 7-11% de los casos. Objetivo : determinar la frecuencia y características de la encefalopatía hipertensiva (EH) secundaria a GNPI en pacientes internados en el Departamento de Pediatría del Hospital Nacional en el periodo enero/2000-diciembre/2018. Materiales y Métodos : Estudio observacional, descriptivo, retrospectivo de pacientes con síndrome nefrítico (SN) con C3 disminuido y normalización a los tres meses, con hipertensión arterial (HTA) severa acompañada de manifestaciones neurológicas (cefalea, náuseas, vómitos, alteración de conciencia, convulsiones), que cedieron al regularizarse la HTA. Se estudiaron las características sociodemográficas (edad, sexo, procedencia, escolaridad de los padres, número de hijos) y clínicas (edema periférico, edema agudo de pulmón, hematuria, y manifestaciones neurológicas). Los datos fueron analizados utilizando estadística descriptiva mediante EPIINFO (CDC, Atlanta), expresando las variables cuantitativas como mediana y rango intercuartílico (RIC) y las cualitativas como frecuencia absoluta y porcentual. Resultados: 27 /160 (16,8%) pacientes, desarrollaron EH. La edad varió entre 3 a 16 años (mediana: 10 años; RIC: 5); el antecedente infeccioso más frecuente fue piodermitis (40,7%), seguido de faringitis aguda (37%). Todos los pacientes presentaron edema periférico y cefalea intensa. La duración de la HTA tuvo una mediana de 5 días (RIC: 4) y los días de internación una mediana de 7 (RIC: 6). Ningún paciente requirió diálisis ni quedó con secuelas, no se registraron óbitos. Conclusión: en pacientes con EH debe considerarse el diagnóstico de GNPI, investigando antecedentes infecciosos y valorando adecuadamente la volemia.

Introduction: Acute post-infectious glomerulonephritis (APGN) can present with complications such as hypertensive encephalopathy in 7-11% of cases. Objective: to determine the frequency and characteristics of hypertensive encephalopathy (HE) secondary to APGN in patients admitted to the Department of Pediatrics of the National Hospital from January/2000 to December/2018. Materials and Methods: This was an observational, descriptive and retrospective study of patients with nephritic syndrome (NS) with decreased C3 and normalization at three months, with severe arterial hypertension (AHT) accompanied by neurological manifestations (headache, nausea, vomiting, altered consciousness, seizures), which subsided when the AHT was controlled. Sociodemographic (age, sex, place of residence, parental education level, number of children in home) and clinical (peripheral edema, acute pulmonary edema, hematuria, and neurological manifestations) characteristics were studied. The data were analyzed using descriptive statistics through EPI INFO (CDC, Atlanta), expressing the quantitative variables as median and interquartile range (IQR) and the qualitative ones as absolute frequency and percentage. Results: 27/160 (16.8%) patients developed HE. Age ranged from 3 to 16 years (median: 10 years; IQR: 5); the most frequent infectious history was pyodermitis (40.7%), followed by acute pharyngitis (37%). All patients presented peripheral edema and severe headache. The duration of AHT had a median of 5 days (IQR: 4) and the days of hospitalization a median of 7 (IQR: 6). No patient required dialysis or was left with sequelae, no deaths were recorded. Conclusion: in patients with HE, the diagnosis of APGN should be considered, a history of infections obtained and adequately assessing fluid status.

ABSTRACT Introduction: Post-infectious glomerulonephritis (PIGN) is a frequent pathology in Pediatrics. Objective: describe the epidemiology of PIGN at a Reference hospital. Materials and Methods: This was a descriptive and observational study. Patients under 16 years of age diagnosed with post-infectious glomerulonephritis were included. We excluded patients with unknown C3, previous renal disease or secondary nephritic syndrome. Variables: sociodemographic factors, season of the year, type of previous infection, creatinine clearance, dialysis requirement.. Data were analyzed using the SPSS program. Results: We enrolled 160 patients, 68.1% of them were male with an M / F ratio of 2.2 to 1. The most affected age group was 6 to 12 years (65%). 60% of the patients came from the rural area, with parents who only a primary-level education and lived in overcrowded conditions. The most frequent clinical form was acute nephritic syndrome (97.5%) and the most prevalent preceding infection was pyoderma (52%). Alteration of renal function was observed in 51.25%, pulmonary edema in 40% and hypertensive encephalopathy in 17%. No patient died. Conclusion: PIGN more frequently affects males, children who live in overcrowded conditions and in from families with low socioeconomic status. Outcomes were good, without any mortality.

Natural environmental water sources in endemic regions of northeastern Brazil are potential reservoirs of viable Mycobacterium leprae

BACKGROUND The detection of live Mycobacterium leprae in soil and animals other than humans suggests that the environment plays a role in the transmission of leprosy. OBJECTIVE The objective of this study was to investigate the presence of viable M. leprae in natural water sources used by the local population in five municipalities in the state of Ceará, northeastern Brazil. METHODS Samples were collected from 30 different sources. Viable bacilli were identified by reverse transcriptase polymerase chain reaction (PCR) of the M. leprae gyrA gene and sequencing of the PCR products. Physicochemical properties of each water source were also assessed. FINDINGS M. leprae gyrA mRNA was found in 23 (76.7%) of the water sources. No association was found between depth of the water and sample positivity, nor was there any association between the type of water used by the population and sample positivity. An association between viable M. leprae and temperature and pH was found. Georeferencing showed a relation between the residences of leprosy cases and water source containing the bacterium. MAIN CONCLUSIONS The finding of viable M. leprae in natural water sources associated with human contact suggests that the environment plays an important role in maintaining endemic leprosy in the study region.

Genotyping and drug resistance patterns of Mycobacterium tuberculosis strains observed in a tuberculosis high-burden municipality in Northeast, Brazil

OBJECTIVES: This study has used a combination of clinical information, spoligotyping, and georeferencing system to elucidate the genetic diversity of the Mycobacterium tuberculosis isolates circulating in a TB-prevalent municipality of Northeast Brazil. METHODS: A total of 115 M. tuberculosis strains were isolated from pulmonary tuberculosis patients from January 2007 to March 2008 in Fortaleza. Drug susceptibility and spoligotyping assays were performed and place of residence of the patients were georeferenced. RESULTS: Of the M. tuberculosis strains studied, 51 (44.3%) isolates were resistant to at least one drug (R-TB) and 64 (55.7%) were sensitive to all the drugs tested (S-TB). A high frequency of resistance was found in previously treated cases (84%) and among new cases (16%; p < 0.001). a total of 74 (64%) isolates were grouped into 22 spoligotyped lineages, while 41 (36%) isolates were identified as new. among the predominant genotypes, 33% were latim american mediterranean (lam), 12% haarlem (h), and 5% u. there was no association of geographic distribution of rt-tb patients as compared to the controls and also the geographic location to the spoligotype patterns. the geospatial analysis revealed that 24 (23%) patients (hot spot zones) either shared the same residence or lived in a close neighborhood of a case. among these concentration zones, the patients lived in the same residence and shared a common genotype pattern and resistance pattern. DISCUSSION: it was observed that the spoligopatterns family distribution was similar to that reported for south america, prevailing the lam and h lineages. a high rate-case among the resistant TB group occurs as a result of transmitted and acquired resistance. A more effective surveillance program is needed in order to succeed in reducing tuberculosis in Northeast Brazil.

Detección de Chlamydia trachomatis, esporos micóticos y Trichomonas vaginalis en mujeres en edad fértil que acuden a los Hospitales San Pablo y Regional de San Lorenzo / Chlamydia trachomatis, fungal spores and Trichomonas vaginalis detection of childbearing age women who attend to San Pablo Hospital and Regional of San Lorenzo

Introducción: Las infecciones vulvo-cérvico-vaginales constituyen la causa más común por la que las mujeres en edad fértil acuden al Ginecólogo. Los agentes etiológicos involucrados incluyen a Chlamydia trachomatis, Trichomonas vaginalis, Cándida albicans, entre otros. La sospecha de vulvo-cervico-vaginitis debe orientar a la realización de estudios de secreción vaginal y muestreo endocervical a fin de detectar el agente causal, establecer un tratamiento específico y disminuir la prevalencia de los mismos así como las complicaciones. Objetivos: Determinar la prevalencia de esporos micóticos, Trichomonas vaginalis y Chlamydia trachomatis en mujeres en edad fértil. Materiales y Métodos: Estudio observacional, descriptivo, de corte transversal y prospectivo, con cuestionario realizado a mujeres en edad fértil que acudieron a los hospitales Materno Infantil San Pablo y Regional de San Lorenzo entre los meses de diciembre de 2010 a febrero de 2011. Resultados: De las 148 pacientes estudiadas, se observó una prevalencia de 27,7% de esporos micóticos, 2% de Trichomonas vaginalis y 4,1% de Chlamydia trachomatis. De las pacientes estudiadas, la mayoría tenían entre 25 a 29 años (26%). Conclusión:La prevalencia de esporos micóticos fue 27,7%, Trichomonas vaginalis 2% y Chlamydia trachomatis 4,1%.

Introduction: the vulvo cervicovaginal infections are the most common reason that women of childbearing age go to the gynecologist. The ethiological agents involved are Chlamydia trachomatis, Trichomonas vaginalis, Candida albicans, among others. The suspicion of cervico-vulvo-vaginitis should guide the studies of vaginal discharge and endocervical sampling to detect the causative agent, to stablish specific treatment and reduce the prevalence of these infections and the complications. Objective: to determine the prevalence of fungal spores, Trichomonas vaginalis and Chlamydia trachomatis in women of childbearing age. Materials and Methods: observational, descriptive, cross-sectional and prospective study performed in women of childbearing age who attended the San Pablo Hospital and Regional of San Lorenzo between the months of December 2010 to February 2011. Results: 148 patients were studied, there was a 27.7% prevalence of fungal spores, 2% Trichomonas vaginalis and 4.1% Chlamydia trachomatis. Of the patients studied, most were between 25 to 29 years (26%). Conclusion: the prevalence of fungal spores was 27.7%, Trichomonas vaginalis 2% and Chlamydia trachomatis 4.1%.
