Objective: To determine the clinical characteristics of secundary amyloidosis. Material and methods: Retrospective study of 115 patients with histopatologic diagnosis of secundary amyloidosis since 1964 up to 1997, performed by renal (97.5%) or minor salival gland biopsy (2.5%).. Results: Conditioning diseases were tuberculosis (90.43%), bronchiectasis (6.08%) osteomielitis (1.74%). The clinical manifestations were edema in 98.2% of cases, proteinuria in 100%, hypotension in 30.43% and diahrrea in 33.91% of the patients. Proteinuria in 24 hour fluctuated between 1.26 gr. and 3.23 gr. The ranged in which serum albumin fluctuated was 0.6 to 3 gr/dl. Only 5% of patients had normal renal function and 95% renal insufficiency. ( Rev Med Hered 1999; 10:45-48 ).

Introduction. Percutaneous renal biopsy is one of the procedures that has contributed most to the knowledge of kidney diseases. Our country does not have updated data on this specific topic. Our objective is to report the proportion of different types of primary and secondary glomerulopathies in renal biopsies performed by the Nephrology Service of the National Hospital Dos de Mayo from 2007 to 2016. Methods. Retrospective case series with review of records clinics in the Nephrology Service of the Dos de Mayo National Hospital. The renal biopsies registry of the Nephrology Department was taken from 2007 to 2016. The results of the reports of renal biopsies were reviewed, the results are reported in proportions. Results. 139 kidney biopsies were recorded. In relation to primary glomerulopathies, the most frequent cause reported was focal and segmental glomerulonephritis, then membranoprol...
