Objectives: This study was planned to define the clinical profile of pulmonary tuberculosis (PTB) patients having renal amyloidosis, to identify the factors responsible for development of amyloidosis, to detect the time period between onset of amyloidosis and PTB, and analyze clinical features of amyloidosis in PTB patients for early diagnosis and timely assessment. Materials and Methods: Patients of PTB having pedal edema, proteinuria, and grossly diseased kidneys on ultrasound abdomen were subjected to renal biopsy and appropriate biochemical investigations. Clinical profile of biopsy proven amyloidosis cases was analyzed. Results: There were 43 patients (32 males, 11 females, age range 20-65 years) having PTB with pedal edema, proteinuria, and renal medical disease on abdominal ultrasound where amyloidosis was confirmed by renal biopsy. The total duration of illness ranged from two months to seven years (mean 2.25 years) and was less than five years in 93% patients. All patients had significant proteinuria. Nephrotic syndrome was seen in 23, hypertension in 19, hypoalbuminemia in 33, hypercholesterolemia in 29, and deranged renal functions in 32 patients. Ninety percent patients had moderate to far advanced pulmonary lesions on chest radiography with smear positivity in 21 patients. Conclusions: Renal amyloidosis is an important complication of PTB and should be suspected clinically in patients presenting with a triad of pedal edema, proteinuria, and medical renal disease on ultrasound. Contrary to general belief, renal amyloidosis may occur in PTB patients having disease for relatively shorter duration, and even if adequately treated.
