INTRODUCTION: Acute glomerulonephritis (AGN) after infection of the upper airways or skin is a kidney disease usually caused by streptococcal nephritogenic strains and may present with sudden onset of gross hematuria, hypertension, edema and, occasionally, acute renal failure, is common in childhood and little incident in adults and younger individuals. OBJECTIVE: To analyze, in a descriptive way, data from the initial presentation of GNA after infection of the upper airways or skin in patients over 14 years of age, with emphasis on its epidemiological and clinical aspects. PATIENTS AND METHODS: We reviewed the clinical data of 82 patients treated at our department during the period 1972-2001, divided into three groups: group 1, with individuals between 14 and 20 years (n = 52), group 2, between 21 and 30 years (n = 19) and group 3, aged >; 31 years (n = 11). RESULTS: There was a predominance of the table among younger patients (group 1), male and white, mostly preceded by infection of the skin, appearing most commonly on lower extremity edema and/or face. In some cases, even with nephrotic syndrome, and hypertension, especially in adults over 30 years (group 3), being the least frequent finding of gross hematuria, and rarely, acute renal failure. CONCLUSION: Our findings underscore the importance of studying the AGN after infection of the upper airways or skin in younger individuals and adults, seeking to better characterize its clinical, mainly because it is a group of patients where the disease is less incident.
