    Lupus nephritis. Part I. Histopathological classification, activity and chronicity scores
    (Health & Medical Publishing Group, 1991) Bates, W. D.; Halland, A.-M.; Tribe, R. D.; Rossouw, D. J.
    Renal biopsy has made a major contribution to the understanding and management of patients with lupus nephritis. In a 5-year retrospective study the renal morphology of 55 biopsies from 51 patients with lupus nephritis was classified acccrding to World Health Organisation criteria. In addition, semi-quantitative activity and chronicity scores were documented. The findings were similar to series from other parts of the world. Of the biopsies reviewed, 6 were class II, 13 class III, 32 class IV and 4 class V. In situations of overlap, segmental proliferative features determined the class to which a biopsy specimen was assigned. Twenty-five of the patients, all WHO class IV, showed activity scores in the severe range. Most of the activity score features were common and easily recognised but necrotising angiitis was only seen in 1 patient. Haematoxylin bodies were difficult to document and the nature and value of the haematoxylin body is questioned.

    Lupus nephritis. Part II. A clinicopathological correlation and study of outcome
    (Health & Medical Publishing Group, 1991) Halland, A.-M.; Bates, W. D.; Tribe, R. D.; Cooper, R.; Chalton, D.; Klemp, P.
    A 5-year retrospective study of lupus nephritis at Tygerberg Hospital was performed in an attempt to document the clinical and histological spectrum of the disease and to study the outcome of the illness. Activity and chronicity scores were used in addition to the World Health Organisation classification system. Of 55 biopsies from 51 patients reviewed, 6 were class II, 13 class III, 32 class IV and 4 class V. There were 19 deaths and in 15 of these the histological classification was IV. Renal failure and infections, often with uncommon pathogens, were the most important causes of death. Serum creatinine values and creatinine clearance at the time of biopsy or follow-up, and hypertension at follow-up showed a significant relationship with outcome. WHO class IV was associated with a poor outcome (P= 0,048) when compared with the other WHO classes combined. Activity scores showed a significant relationship to the outcome (P = 0,018). The anticardiolipin antibodies IgG and IgM were not associated with WHO class or outcome. The study revealed a spectrum of histological results similar to that of other studies, with a high mortality rate, particularly in class IV disease. Poor renal function, persistent hypertension, histological classification IV, and high activity scores were found to be important prognostic indicators.
