ABSTRACT
Tubulointerstitial lesions (TIL) such as interstitial inflammation, fibrosis and tubular atrophy are frequently found in classes of lupus nephritis. A retrospective study evaluate lupus nephritis, the relationship between TIL and glomerular lesions, and the significance of TIL in assessing the severity and prognosis for cases of lupus nephritis. Between June 1983 and Jan 1990, 492 renal biopsies were performed. Lupus nephritis was diagnosed in 37 patients who fulfilled the American Rheumatology Association (ARA) criteria for Systemic lupus erythematosus (SLE). The results showed a significant correlation between degree of TIL and impairment of renal function. Degree of TIL and severity of glomerular lesions must be considered simultaneously to predict renal function of patients with lupus nephritis.
