Histopathologic studies were performed on systemic amyloidosis of leprosy patients in two Japanese leprosaria. Amyloid deposits were observed in 23 of 50 cases (46%) autopsied from 1955 to 1959 (Group A), and in 17 of 110 cases (15.4%) from 1962 to 1971 (Group B). These incidences are higher than those of the pre-chemotherapeutic period in Japan. The average age of amyloidal cases was significantly lower than that of nonamyloidal cases in both groups. There was no predilection for either type of leprosy in Group B. Pyelonephritis was frequently observed in both groups; the incidence of amyloidosis in Group B correlated with pyelonephritis. Amyloid deposits may be related to renal disorders associated with lepra reactions or inflammatory lesions. Amyloidosis has been classified into primary and secondary type, but the criteria seem uncertain. We referred to a classification based on immunologic finginds. In the severely affected lesion of the kidney of one case, we observed foci of foreign body type giant cells, suggesting a possibility of resorptive process in human renal amyloidosis.

A study of 64 cases of leprosy (44 lepromatous and 20 nonlepromatous) revealed that the duration of the disease has a significant relationship with renal involvement (chi 2 = 16.9, P less than 0.001). Proteineuria, microscopic haematuria, granular and hyaline casts are mainly seen in lepromatous cases and specially with lepra reaction (100%) while few of the non-lepromatous (2%) cases may show these abnormalities. Impaired renal functions are mostly observed in lepromatous leprosy (62.9%) specially those with lepra reaction (100%) while 2% nonlepromatous cases have these impaired renal functions. Histo-pathological studies revealed non-specific changes in 44.4% of cases and those of chronic pyelonephritis in 15.5% of the cases. Renal amyloidosis is less common occurrence (4.4%). The specific lesion, that is 'leproma kidney', is rare and seen in one patient only. Acid fast bacilli could not be seen in any of the kidney tissue. It is therefore, concluded that the renal involvement in the form of inflammatory lesions and non-specific changes in the glomeruli and tubules are very common in lepromatous leprosy specially during the reactive phase.

A study of 133 necropsies on leprosy patients showed that renal disease, pyogenic infections, and tuberculosis were the most frequent causes of death. Major kidney lesions encountered included glomerulonephritis of different types, pyemic abscess, acute tubercular necrosis, amyloidosis, and chronic pyelonephritis. In many cases the renal lesions were secondary to infections in other organs. Case control studies are required to determine if the high prevalence of these diseases is related to leprosy, its complications, or its therapy, per se, or if it is a reflection of the disadvantaged and poor socioeconomic status of these patients.

Using medical manuscripts and texts from the Byzantine period (330-1453), this article describes various, to date little discussed, aspects of Byzantine nosology, public health and therapeutics. Many diseases in the Byzantine era were widespread and had a high morbidity such as respiratory disease, various kinds of anaemia, pestilential diseases (e.g. quartan fever, plague, dysentery and cholera), parasitic diseases, orthopaedic, rheumatic and psychiatric disorders, trachoma and alcoholism. Other very serious and relatively frequent conditions included leprosy, mania, gout, cancerous tumours and ulcers. Important elements of nephrology and various renal diseases were described and investigated, such as acute and chronic renal failure, acute and chronic nephritis, pyelonephritis, necrotic renal diseases, crush syndrome, and ulcers of the kidneys, i.e. tuberculosis or renal tumours. The microhistology and physiology of the kidneys were first studied by Oribasius, who discerned the existence of the capillaries--tau rho iota chi omicron epsilon iota delta eta--some centuries before Malpighi. He also correctly described the blood circulation, general and pulmonary, as a precursor to Harvey. The first hospitals were organised during the Byzantine period, and the practice of Byzantine medical science and its social applications were regulated by a special medical legislation and deontology. Byzantine medicine was fruitfully connected with the Christian faith and developed the supreme model of the saints unmercenary--alpha nu alpha rho gamma epsilon rho omicron iota--physicians such as Cosmas and Damian (3rd century), Panteleemon (3rd-4th centuries) and the women physicians and miracle-worker saints, Zenais and Philonilla (1st century), the 'friends of peace', and Hermione (1st-2nd centuries).

Leprosy is a chronic disease caused by Mycobacterium leprae, highly incapacitating, and with systemic involvement in some cases. Renal involvement has been reported in all forms of the disease, and it is more frequent in multibacillary forms. The clinical presentation is variable and is determined by the host immunologic system reaction to the bacilli. During the course of the disease there are the so called reactional states, in which the immune system reacts against the bacilli, exacerbating the clinical manifestations. Different renal lesions have been described in leprosy, including acute and chronic glomerulonephritis, interstitial nephritis, secondary amyloidosis and pyelonephritis. The exact mechanism that leads to glomerulonephritis in leprosy is not completely understood. Leprosy treatment includes rifampicin, dapsone and clofazimine. Prednisone and non-steroidal anti-inflammatory drugs may be used to control acute immunological episodes.

Renal involvement in 20 lepromatous leprosy (LL) and 5 non- lepromatous patients was assessed by (a) biochemical analysis of blood and urine, (b) renal functional tests, and (c) histopathological examination of renal biopsies. Ten age-matched healthy normals formed the control group. LL patients had a varying degree of renal involvement as indicated by the presence of pus cells, granular, hyaline and red cell casts, reversal of albumin/globulin ratio and lowered creatinine clearance rates. Renal biopsies showed significant histopathological lesions in 50% of lepromatous as compared to 20% of the non-lepromatous patients. The pathological changes were predominantly of chronic glomerulonephritis followed by chronic pyelonephritis and interstitial nephritis. Surprisingly none of the patients studied showed granulomas, acid-fast bacilli or amyloid in the kidney.
