The solid phase Clq radioimmunoassay was used to detect immune complexes in sera from patients with systemic lupus erythematosus (14/25), rheumatoid arthritis (4/5), vasculitis (5/15), infective endocarditis (2/2), acute rheumatic fever (2/3), pre-eclamptic toxaemia (0/14), lung cancer (3/7), glomerulonephritis (26/98) and renal transplant patients (0/5). The best correlation with disease activity was seen in systemic lupus erythematosus and infective endocarditis where serial immune complex determinations were clearly of value in monitoring therapy. The findings in primary glomerulonephritis indicate only a limited usefulness of the assay in that serum immune complexes were detected in a minority (22/73) of patients with glomerular immune deposits. In particular the data do not support a role for Clq fixing immune complexes in the pathogenesis of membranous glomerulonephritis or in pre-eclamptic toxaemia.

Membranous glomerulonephropathy (MGN) in South African black and mixed race children with the nephrotic syndrome is much commoner than in First-World countries. In this survey of 388 nephrotic children MGN was found in 51.9% of black and 20.9% of mixed race boys, and 25% of black and 5.6% of mixed race girls respectively, but was not present in 53 white and Asiatic nephrotic children. Aetiological or associated factors were documented in 84%: hepatitis B virus infection in 73%, congenital syphilis in 6% and systemic lupus erythematosus, D-penicillamine toxicity and Salmonella infective endocarditis in 1 case each. The prognosis depends on the cause and is much better than for adults with idiopathic MGN. After an average follow-up period of 4.5 years the overall remission rate was 78% and mean time to remission 30 months. One patient with syphilitic MGN died 15 years later; 3 patients are in mild renal failure. Corticosteroids and other immuno-suppressive therapy were ineffective and may do harm. The frequent occurrence of MGN is related to the high prevalence of predisposing infections in the affected population groups, and socio-economic rather than ethnic factors are important.

An autopsy case of membranous glomerulonephritis associated with enterococcal endocarditis was reported. Although enterococcal antigen was not identified in glomerular deposits, the eluate from the patient's renal tissue was shown to specifically recombine with cells of the enterococcus isolated from his own ante mortem blood. Hypocomplementemia, circulating immune complexes and antienterococcal antibodies were also observed. These findings suggest that enterococcus-related immune complexes played a role in the pathogenesis of glomerulonephritis associated with enterococcal endocarditis in this patient.
