RESUMEN

OBJECTIVE: To analyze the effectiveness, safety, outcomes, and associated factors of tuberculosis preventive treatment (TPT) in children and adolescents in Paraná, southern Brazil. METHOD: This was an observational cohort study with a retrospective collection of secondary data from the TPT information systems of the state of Paraná from 2009 to 2016, and tuberculosis in Brazil from 2009 to 2018. RESULTS: In total, 1,397 people were included. In 95.4% of the individuals, the indication for TPT was a history of patient-index contact with pulmonary tuberculosis. Isoniazid was used in 99.9% of the cases with TPT, and 87.7% completed the treatment. The TPT protection was 98.7%. Among the 18 people who had TB, 14 (77.8%) became ill after the second year of treatment, and four (22.2%) in the first two years (p < 0.001). Adverse events were reported in 3.3% of cases, most of them were gastrointestinal and medication was discontinued in only 2 (0.1%) patients. No risk factors associated with the illness were observed. CONCLUSIONS: The authors observed a low rate of illness in pragmatics routine conditions in TPT for children and adolescents, especially within the first two years after the end of treatment, with good tolerability and a good percentage of adherence to the treatment. TPT should be encouraged to achieve the goals of the End TB Strategy of the World Health Organization as an essential strategy to reduce the incidence rate of the disease, but studies with new schemes must continue to be carried out in real-life scenarios.

RESUMEN

Introduction: Children living with HIV/AIDS require specialized care. Objective: To describe clinical and epidemiological characteristics of patients living with HIV/AIDS. Methods: Observational, descriptive study using medical records data of patients with HIV/AIDS under 14 years of age. Approved by the institution's Ethics Committee under number 1,432,517. Results: 60 cases were included; the median follow-up duration was 6.8 years; 50.0% were male; 88.3% were white; 75.0% were from the capital and metropolitan region. Prenatal records were available for 51 cases, but only 44.6% received antiretroviral therapy (ART) during pregnancy (mean duration of 3.3 months). HIV diagnosis was based on clinical symptoms in 28.3% of the cases, occurring in similar proportions for both childhood common infections and opportunistic infections. According to the CDC clinical classification (1994), at the start of follow-up, 56.6% of patients had moderate or severe symptoms, which would be reduced to only 18.3% upon reclassification at the last visit (p=0.016). Initially, 41.7% showed evidence of immunosuppression, compared to 19.9% at the time of the study (p=0.5). Only 6.6% remained asymptomatic. A decrease in the average number of hospitalizations was observed during follow-up. Conclusion: Among the cases diagnosed based on clinical symptoms, half were attributed to common childhood infections and lacked immunosuppression

Introdução: Crianças que vivem com o vírus da imunodeficiência humana ­ HIV/AIDS requerem atendimento especializado. Objetivo: Descrever características clínicas e epidemiológicas de pacientes que vivem com HIV/AIDS. Métodos: Estudo observacional, descritivo, com dados de prontuários de pacientes com HIV/AIDS de até 14 anos de idade incompletos, aprovado pelo Comitê de Ética em Pesquisa da instituição sob o número 1.432.517. Resultados: Foram incluídos 60 casos. A mediana de acompanhamento foi de 6,8 anos; 50,0% eram do sexo masculino; 88,3% brancos; 75,0% naturais da capital e região metropolitana. Em 51 prontuários havia descrição de pré-natal, porém apenas 44,6% fizeram uso de terapia antirretroviral (TARV) na gestação (tempo médio de 3,3 meses). Em 28,3% o HIV foi pesquisado por sintomas clínicos, que ocorreram em proporções similares tanto por infecções habituais da infância como por oportunistas. De acordo com a classificação clínica dos Centers for Disease Control and Prevention ­ CDC (1994), ao início do acompanhamento, 56,6% dos pacientes apresentavam sintomas moderados ou graves e, na última consulta, se fossem reclassificados, seriam apenas 18,3% (p=0,016). Incialmente, 41,7% apresentavam evidência de imunossupressão, comparativamente aos 19,9% na ocasião do estudo (p=0,5). Apenas 6,6% permaneceram assintomáticos. Com o acompanhamento, verificou-se diminuição na média do número de hospitalizações. Conclusão: Dos casos que apresentaram seu diagnóstico por sintomas clínicos, metade foi por infecções habituais da infância e sem imunossupressão

RESUMEN

Racional: O impacto da infeção congênita e perinatal pelo CMV na saúde pública é muito relevante, sendo a infecção congênita mais predominante, porém pouco abordada. Objetivos: Avaliar o perfil dos pacientes com diagnóstico positivo para infecção congênita e perinatal por citomegalovírus. Métodos: Estudo observacional, analítico, transversal, com coleta de dados retrospectiva. Os dados foram obtidos segundo critérios demográficos, imunológicos, virológicos, terapêuticos e de análise dos exames de imagem.Resultados: Foram coletados dados de 35 pacientes que inicialmente receberam o diagnóstico, entretanto somente 17 preenchiam os critérios de inclusão. Conclusões: A amostra estudada foi de casos sintomáticos e reflete proporcionalmente pouco de uma doença tão prevalente. Isto se deve a dificuldade diagnóstica maternofetal; portanto, é importante enfocar e investir em pesquisa e novas ferramentas para um diagnóstico precoce.

Background: The impact of congenital and perinatal CMV infection on public health is very relevant, with congenital infection being the most prevalent, but little addressed. Objective: To evaluate, through the analysis of medical records, the profile of patients with diagnosis of congenital or perinatal cytomegalovirus infection during the stipulated study time. Methods: Observational study, analytical, cross-sectional, with retrospective data collection. The data were obtained according to demographic, immunologic, virologic and therapeutic criteria, as well as imaging exams analysis. Results: Data were collected from 35 patients who initially received the congenital or perinatal infection diagnosis during the time stipulated by the study, but only 17 met the inclusion criteria. Conclusions: The studied sample of symptomatic patients proportionally reflects little of such a prevalent disease. This happens because of the difficult mother-fetus diagnosis. Therefore, it is important to focus and invest in research and new tools seeking the early diagnosis.

RESUMEN

The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

RESUMEN

Changes in immune system functions are one of the most important consequences of human immunodeficiency virus (HIV) infection. Studies have reported a higher prevalence of disease mediated by immunological hypersensitivity mechanisms in HIV-positive patients. This study aims to observe how immunological changes in HIV-infected children interfere in atopy determinants. Fifty-seven HIV-positive children were studied between June 2004-August 2005 to evaluate the possible modifications in atopy diagnosis from prick test environmental allergen reactivity. Patients were subjected to two evaluations: on both occasions, atopic and non-atopic groups were correlated with immunological (CD4+ and CD8+ lymphocyte concentrations and serum levels of IgA, IgM, IgG and IgE) and viral parameters (HIV viral load). The percent atopy was 20.05 in the first and 29.82 in the second evaluation and atopy was diagnosed in patients without immunosuppression or with moderate immunosuppression. Six patients changed from a negative to a positive atopy profile. One patient with a decreased CD4+ T lymphocyte concentration failed to demonstrate prick test positivity between evaluations. Multivariate analysis showed that the variables associated with atopy diagnosis included a personal history of allergic diseases as well as elevated IgE for age and elevated IgE levels. Atopy development in HIV-infected children seems to be modulated by genetic and environmental factors as well as immunological condition.

RESUMEN

This study evaluated the degree of neurological compromise in HIV-infected children accompanied by the outpatient clinic of infectious diseases and pediatric neurology of the Clinical Hospital of the Federal University of Paraná (UFPR) starting in 1995. Long-term progressive prospective and cross sectional study of 88 children infected by HIV and 84 seroreverter children, using data from general neurological examinations, neuroimaging procedures (brain CT scan) and neurodevelopmental tests (CAT/CLAMS and DENVER I and II). Neurological and neurodevelopmental alterations were found in 82 percent of the HIV-infected patients and in 36 percent of the HIV-seroreverter group (P <0.01). In the CAT/CLAMS test, the development quotient (DQ) of the HIV-infected group was significantly lower than that of the HIV-seroreverter group. CAT/CLAMS scores lower than 70 (mental deficiency) were found in 31 percent of the HIV-infected patients during the first year of life and in only 1 percent of the patients of the HIV-seroreverter group, demonstrating the validity of this screening test for precocious detection of alterations in the neurodevelopment of infected patients. The same occurred with the Denver I and II tests, as the HIV-infected group failed more frequently than the HIV-seroreverter group. Nine HIV-infected children presented altered brain CT scans; calcification of basal ganglia was the main finding (five cases). Encephalopathy due to HIV causes early arrest of neurodevelopment, which can be detected with screening tests during the first year of life.

RESUMEN

The aim of the study was to detect neurological abnormalities in human immunodeficiency virus (HIV) infected children. This was achieved by a prospective evaluation, from November/1995 to April/2000, of 43 HIV infected children (group I) and 40 HIV seroreverters children (group II) through neurological exam and neurodevelopmental tests: Denver Developmental Screening Test (DDST) and Clinical Adaptive Test / Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS). A control group (III), of 67 children, were evaluated by CAT/CLAMS. Hyperactivity, irritability and hypotonia were the findings on neurological examination, without statistical differences between group I and II. On CAT/CLAMS, the group I developmental quotient (DQ) was significantly lower than the other groups. The same occurred in DDST, with group I presenting significantly more failures than group II. Nineteen HIV children of group I had brain computed tomographic scan, with abnormalities in three of them (basal ganglia calcification, white matter hypodensity and asymmetry of lateral ventricles). We conclude that in HIV infected children a neurodevelopment delay occur early in the disease, and it can be detected by screening tests

RESUMEN

A dilataçäo aneurismática dos vasos do polígono de Willis é manifestaçäo incomum da infecçäo pelo vírus da imunodeficiência adquirida (HIV), tendo sido relatados, até o momento, 15 casos na literatura. O presente estudo tem por objetivo relatar um novo caso dessa apresentaçäo rara, além de revisar aspectos importantes relacionados à mesma. Um paciente, do sexo masculino, 6 anos de idade, com síndrome da imunodeficiência adquirida (AIDS) de transmissäo perinatal e tetraparesia, desenvolveu sintomas caracterizados por episódios de crises distônicas. A tomografia computadorizada de crânio, que inicialmente era normal, mostrou dilataçäo aneurismática dos vasos do polígono de Willis. A revisäo de literatura demonstra que os principais achados patológicos em casos similares, säo, principalmente, fibrose de camada média com destruiçäo da lâmina interna e hiperplasia da íntima. A etiologia da vasculite näo é conhecida, acreditando-se que o vírus da varicela-zoster e o próprio HIV possam estar relacionados à mesma. Conclui-se que, apesar de incomum, tal complicaçäo apresenta grande importância pelo fato dos aneurismas colocarem esses pacientes em grupo de alto risco para acidentes vasculares. A sobrevida relatada na literatura é de menos de 6 meses após o diagnóstico da arteriopatia aneurismática cerebral
