Renal amyloidosis secondary to childhood tuberculosis: a report of two cases.
Childhood renal amyloidosis is a rare entity and is mostly secondary in nature. We describe two cases of renal amyloidosis in association with childhood tuberculosis. The first case was a 10-year-old girl who presented with abdominal tuberculosis and nephrotic syndrome, while the second case was a 5-year-old boy who presented with disseminated tuberculosis and nephrotic syndrome. They were found to have amyloidosis on renal biopsy. The former was treated with anti-tubercular drugs, while the latter required anti-tubercular drugs and steroids. Both the cases showed clinical improvement with remission of nephrotic syndrome. Successful treatment of tuberculosis can result in remission of nephrotic syndrome due to secondary renal amyloidosis. It is important, especially in developing countries, to be aware that tuberculosis continues to be part of the differential diagnosis of amyloidosis in children.
