Three patients having lepromatous leprosy developed acute renal failure. Two patients completely recovered and one was left with a moderate degree of renal insufficiency. Renal tissue obtained by percutaneous biopsy revealed acute tubular necrosis in two and diffuse crescentic glomerulonephritis in the third case.

Acute renal failure due to intravascular hemolysis is a common clinical problem in North Indian patients. It constituted 21.5 percent of 325 patients dialyzed for acute renal failure over an 11-year period at Chandigarh. Thirty patients had developed acute intravascular hemolysis in association with erythrocyte glucose-6 phosphate dehydrogenase (G-6PD) deficiency, 17 due to copper sulphate intoxication and 8 due to envenomation by snakes. Less frequent causes were insect stings, incompatible blood transfusion, intake of anti-leprosy drug--dapsone in non-G-6PD-deficient patients, and mercuric chloride toxicity in two patients each; naphthalene poisoning in one; and uncertain causes in six patients. Renal histology was available in 55 patients. Acute tubular necrosis was seen in 54 and bilateral diffuse cortical necrosis in one patient. Fifty patients (71.43 percent) survived and 20(28.6 percent) diet. G-6PD erythrocyte deficiency, which is present in 4.5 percent of the North Indian population, was the most frequent cause of acute renal failure in this group.

Renal involvement in Hansen's disease was evaluated in 94 Portuguese patients, average age and duration of disease of 47.6 and 6.8 years respectively. Sixty-seven were studied retrospectively and 27 prospectively; renal biopsy was obtained in 4, fat-tissue needle aspiration for amyloidosis in 20, and tubular function was tested in ten. Mild proteinuria and/or haematuria was found in 33 patients, the severity increasing during erythema nodosum leprosum reactions, but without overt nephritic or nephrotic syndrome. Two patients had renal amyloidosis on biopsy and two more were confirmed by fat biopsy, a 10.5% incidence in those studied prospectively; all but one were of the lepromatous type, with frequent bouts of erythema nodosum leprosum. The two other renal biopsies showed mesangial glomerulonephritis, and one unexplained acute tubular necrosis; none had immune deposits by immunofluorescence. Proximal acidification was always normal, distal acidification tested by bicarbonate infusion was abnormal in one of nine patients, and six of nine patients had concentration defects. Leprosy causes frequent urinary sediment changes and concentration defects, usually without clinical expression; proteinuria and/or glomerular involvement is mainly due to amyloidosis.

Nephrotic syndrome was the commonest clinical presentation among 2827 consecutive adult Indian patients from whom adequate kidney biopsies were obtained for suspected renal disease. In 83 per cent of cases the nephrotic syndrome was due to minimal change disease, focal segmental glomerulosclerosis, mesangiocapillary glomerulonephritis, membranous usually secondary to tuberculosis or leprosy, was present in only 34 patients. Acute nephritis, the next most frequent clinical presentation, was due to diffuse endocapillary proliferative, crescentic or mesangial proliferative glomerulonephritis in 88 per cent of cases, almost half of whom had elevated serum streptococcal antibody titres. Eosinophilia showed a highly significant association with diffuse endocapillary proliferative and mesangiocapillary glomerulonephritis. Idiopathic IgA nephropathy was present in only 10, and antiglomerular basement membrane antibody disease in only one, of the 238 patients whose biopsies were studied by immunofluorescence. Complications of pregnancy accounted for 70 per cent of cases of cortical necrosis. Acute gastroenteritis, septicaemia, abortions, snake bite and allopathic and indigenous medicines were important causes of acute tubular necrosis.

Nephropathy as the sequences of Hansen's disease before and after the introduction of chemotherapy was compared referring to the report by Hayashi in 1943 and the summary of the autopsy reports from 1978 to 1981 at National Hansen's disease hospital Zenseien. Unlike the high rates of tuberculosis as the cause of death before the introduction of chemotherapy (41.3%) those thereafter decreased to be negligible. On the other hand the comparison of the rates of nephropathy with the same way as that of tuberculosis was impossible since the description about nephropathy by Hayashi was not sufficient to characterize each nephropathy since he included arteriolitis, glomerulonephritis and interstitial nephritis together in the term of nephritis. Death rate due to nephritis among Hansen's disease patients according to Hayashi at that time was 21.2% which was twice as many comparing to that in the other cases. According to the report about the cases of Zenseien those reported to have glomerulonephritis was 37.3% though those were not necessarily listed as the cause of death. Also the nephropathy including fibrinoid angitis with occasional microaneurysmal dilatation of afferent arteries, glomerulitis, sclerosis and stricture of efferent arteries likewise ischemic acute tubular necrosis possibly as the result of these angiopathy seemed to be present. These vascular changes partially resemble to that of microscopic periarteritis nodosa but seems to be common in the smaller arteries. In conclusion, unlike the case of tuberculosis the rate of nephritis including glomerulitis, arteriolitis and interstitial nephritis as Hayashi used as his criteria does not seem to have decreased. Therefore, the critical analysis of the nephropathy especially of that relating to the arteriolitis should be done to obtain the knowledge to suppress its occurrence.

Renal diseases unique to the tropics are those that occur in association with infectious diseases including dengue hemorrhagic fever, typhoid fever, shigellosis, leptospirosis, lepromatous leprosy, malaria, opisthorchiasis, and schistosomiasis. These renal complications can be classified on the basis of their clinical and pathologic characteristics into acute transient reversible glomerulonephritis, chronic progressive irreversible glomerulonephritis, amyloidosis, and acute renal failure (ARF) resulting from acute tubular necrosis, acute tubulointerstitial nephritis, and thrombotic microangiopathy. Certain primary glomerular diseases including immunoglobulin (Ig) M nephropathy and focal segmental and global glomerulosclerosis are prevalent in some tropical countries. Renal complications of venomous snakebites also are common in the tropics. This article discusses and summarizes important works in the literature in respect to the clinical syndromes, pathologic features, and pathogenesis of tropical renal diseases both in humans and experimental animal models.

Renal involvement in leprosy has been reported rarely in the literature. Acute kidney injury in patients with leprosy is uncommon and may occur due to acute tubular necrosis, drug-induced interstitial nephritis and rarely crescentic glomerulonephritis. The latter with histologic confirmation of the diagnosis has been reported in very few cases of leprosy. A 25-year-old male, on therapy for multibacillary leprosy, was found to have deranged renal functions on evaluation for a history of nausea, vomiting, swelling and episode of haematuria. Kidney biopsy was performed twice over a period of 2 weeks, showing progression from diffuse proliferative glomerulonephritis to crescentic glomerulonephritis, pauci-immune in nature. The patient was treated aggressively with intravenous steroids, following which his renal functions stabilized. Crescentic glomerulonephritis, an extremely rare phenomenon in leprosy, should be considered in these patients presenting with features of acute kidney injury. Timely performed renal biopsy assists in accurate diagnosis and appropriate management of the patient, hence preserving renal parenchyma. Rapid progression from diffuse proliferative glomerulonephritis to crescentic glomerulonephritis in a patient with leprosy is described herein for the first time in the literature.

Chronic kidney disease (CKD) is a major global public health problem. But kidney involvement is more common and appears more severe in Africa than in developed countries. The likely causes of end stage renal disease (ESRD) or CKD stage 3 and above in developed countries are diabetes, hypertension and less frequently glomerular diseases. In contrast, in decreasing order in Africa are glomerulopathies, hypertension and diabetes. The reasons for this preponderance of glomerular diseases are not fully known but may be linked to the persistence or reemergence of tropical diseases. This study reviews the kidney involvements more associated with common tropical diseases including HIV/AIDS. The most common HIV/AIDS lesion is a specific focal and segmental glomerulosclerosis (FSGS) termed HIV-associated nephropathy (HIV-AN). Renal complications of tropical parasites are heterogenous. Various glomerulopathies like FSGS occur during various filariasis infections. Schistosoma mansoni is responsible for membranoproliferative glomerulonephritis and amyloidosis. Human African trypanosomiasis is associated with cryoglobulinemic membranoproliferative glomerulonephritis. The Plasmodium malariae is mainly responsible for membranoproliferative glomerulonephritis. Acute patterns (acute tubular necrosis or acute postinfectious glomerulonephritis) are observed during Plasmodium falciparum infection. Several other viral, bacterial or mycobacterial infections like leprosy and tuberculosis still prevalent in Africa can also affect the kidney. Sickle cell disease is responsible for a variety of renal injuries. In conclusion, kidney lesions linked to tropical diseases partly explain the peculiar pattern of CKD of the black race and play a significant role in the current outbreak of the CKD in Subsaharan Africa.
