RESUMEN
45 Children suffering from rheumatic fever and its sequele were chosen for the study of renal function and the results were compared with samples taken from 15 healthy children [controls]. Full history, clinical examination, chest x-ray, ECG, routine investigations including complete blood picture, ESR, ASOT, and specific investigations for renal function namely blood urea nitrogen, serum creatinine level, and beta2 microglobulin level were done for every subject in the study. The serum creatinine level showed no statistical significance - while beta2 micro globulin [beta2 MG] showed statistical significant values when we compared the patients with the control group also the blood urea nitrogen showed statistically significant results. Although BUN, and beta2 MG are statistically significant, yet the results do not indicate either renal failure or glomerular insufficiency
