[Tubulointerstitial nephritis in chronic viral diseases of the liver].

The paper reports 4 cases of tubulointerstitial nephritis (TIN) in chronic diffuse diseases of the liver (CDDL). The latter comprised such conditions of virus etiology as chronic active hepatitis, chronic lobular hepatitis. TIN presented with pronounced renal tubular affections: defects of concentration capacity, distal renal tubular acidosis, renal diabetes insipidus. In 3 cases renal lesions occurred 1 and 6 years prior to CDDL detection. TIN pathogenesis in CDDL of viral etiology is discussed.
