A 17-year old-male presented with a 6-week history of weight loss, lassitude and calf pains. On examination he was very pale. Laboratory tests showed a very high erythrocyte sedimentation rate (155 mm in the first hour), anaemia (haemoglobin 10.1 g/dl), and a raised serum creatinine of 1.54 mg/dl. Microhaematuria (5-10 erythrocytes/microliter) and pronounced pyuria (500 leucocytes/microliter) were present, but the urine was sterile and there was no increase in albumin excretion. The serum IgG was raised to 75.7 g/l, suggesting an autoimmune disorder. Anti-nuclear antibodies (titre 1 : 1920) and anti-double-stranded DNA antibodies (31 U/ml) were present, while the serum complement C4 was decreased to 0.11 g/l. Renal histology showed an interstitial nephritis without glomerular involvement, while the bone marrow showed vasculitis accompanied by a prominent plasma-cell infiltrate. A diagnosis of interstitial nephritis associated with systemic lupus erythematosus was made, with asymptomatic cardiac and hepatic involvement. Renal function recovered rapidly with prednisolone therapy (initial dose 2 mg/kg.d). While glomerulonephritis is the most common lupus-associated renal disorder, isolated interstitial nephritis may occur in some cases, often with an absence of proteinuria.

This paper describes the clinical symptoms and signs of Balkan endemic nephropathy (BEN). The initial asymptomatic period followed by weakness and lassitude during renal insufficiency is emphasized. Non-characteristic lumbar pain may be present and episodes of macrohaematuria may occur. There is no fever, no severe dysuria, and no general disease preceding the symptoms. No oedema of the nephrotic type is recognized. Working capacity is unaffected until the late stage of the disease. In the advanced stages pallor of the skin and xantochromia of palms and soles are noticeable. Blood pressure is normal, but in the advanced phase may be elevated. In the uraemic phase a full uraemic syndrome is found. Urothelial tumours are frequent, occurring in 2-47% of cases; tumour cells may be found in the urine. Proteinuria of tubular type may be found early; in the uraemic phase it is constant. In the urinary sediment there are scarce white and red blood cells (the latter episodically abundant). Bacteriuria is present in about 20% of women patients. Glucosuria (less than 10%) and aminoaciduria (less than 10%) have been reported. In the early stages of BEN the urine concentration capacity is impaired earlier than renal blood flow and glomerular filtration rate. Enzymuria is present in the early phases. Tamm-Horsfall protein may be increased in the urine. Normo- or hypochromic normocytic hyporegenerative anaemia is a frequent finding. Bone marrow and leucocytes are normal. Serum proteins and immunoglobulins are not altered. Complement is normal; anti-glomerular basal membrane and anti-tubular basal membrane are negative. On radiography, kidney size varies from normal to the size of a small contracted kidney. The clinical picture of the disease is that of a slowly progressing tubulo-interstitial chronic nephritis.
