Resumen
Objetivo: Avaliar a prevalência do prurigo estrófulo em crianças infectadas pelo HIV e sua distribuição conforme as categorias imunológicas e a carga viral. Métodos: Estudo prospectivo, observacional de pacientes menores de 14 anos infectados pelo HIV que consultaram o Serviço de Infectologia Pediátrica do HC da UFPR. Uma avaliação foi realizada por Dermatopediatra e considerado caso de prurigo estrófulo o paciente com alergia a picadas de insetos e lesões clínicas compatíveis. A determinação dos valores de linfócitos T CD4+ e da carga viral foi feita no momento da consulta. Os pacientes foram estratificados nas categorias imunológicas. O estudo estatístico foi realizado com nível de significância de 5%. Resultados: Foram examinadas 127 crianças. Prurigo estrófulo foi observado em 33 pacientes, com média de 3 anos de idade e predominou nos meses quentes. Prurigo estrófulo foi mais prevalente nos pacientes com ausência de imunodeficiência. Porém, não houve diferença da média do número de cópias virais em pacientes com ou sem a dermatose. Conclusões: O prurigo estrófulo é observado em crianças infectadas pelo HIV na classificação imunológica "sem imunossupressão". Estes achados sugerem que modificações imunológicas, promovidas pelo HIV em algumas fases da doença, podem favorecer o desenvolvimento de hipersensibilidade à picada dos insetos.

Abstract
Objective: To evaluate the prevalence of prurigo strophulus in HIV infected children and whether its distribution conforms to immunological categories and viral load. Methods: Prospective observational study in HIV infected children under 14 year olds who were seen at the Pediatric Infectology Service, UFPR University Hospital. An evaluation was performed by pediatric dermatology specialists who considered prurigo strophulus as an allergy to insect bites and compatible clinical lesions. CD4+ T lymphocyte count and viral load were determined at consultation time. Patients were stratified by immunological category. Statistical analysis was performed with a 5% significance level. Results: Prurigo strophulus was seen in 33 of 127 children, at a mean age of 3 years, with predominance in warmer months and in patients without immunodeficiency. There was no difference in mean number of viral copies between patients with or without the dermatosis. Conclusions: Prurigo strophulus is seen in HIV infected children immunoclassified as without immunosuppression. These findings suggest that immunological changes promoted by HIV in some phases of the disease could help hypersensitivity to insect bites develop.
