Peroperative and postoperative blood loss was studied in 20 patients. Both peroperative and postoperative blood loss was found to correlate together (p less than 0.05) and with the weight of resected tissue (p less than 0.05). The characteristics of the postoperative blood loss demonstrated a strong negative correlation with time, and calculation of the t50 showed that a 50% reduction in postoperative blood loss occurred within 16 h.

Lupus nephritis has been described as the most serious complication of systemic lupus erythematosus (SLE) and the strongest predictor of poor outcome. While the incidence of childhood SLE is relatively low, renal involvement appears to be more common and more severe in childhood SLE. This study aims to characterize the features and outcome of renal involvement in childhood-onset SLE based on a study of 100 Egyptian patients (mean age at diagnosis 10.1 years, range 2-17 years). Initial data regarding disease manifestations and biopsy findings were reviewed. Disease activity was assessed using SLEDAI scores. Follow-up data (mean duration 6 years) were noted regarding specific treatment, response, complications and renal survival. Initial renal involvement was present in 78 patients, including 66 with hypertension and 23 with renal impairment. Pathologically, class IV nephropathy was found in 18 patients, class V in 9 and low-grade lesions (class II-III) in 49. Twenty patients required follow-up biopsy, and all transformations were observed. SLEDAI scores significantly decreased from initial (mean ± SD) of 21.4 ± 7.3 to 13.4 ± 7.8, in association with response to therapy (P < 0.0001). Poor response was associated with initial hypertension and renal impairment but not with initial SLEDAI score or pathological class. The projected renal survival was 82.4 and 64.7% 5 and 10 years from diagnosis. Early renal involvement in childhood SLE is common, serious and requires proper evaluation and management.
