Decrease in circulating immune complexes during hemodialysis.

Raji cell radioimmunoassay and Clq solid phase radioimmunoassay were used to determine serially circulating immune complexes in a patient with rapidly progressive glomerulonephritis who was receiving hemodialysis therapy. Initiation of hemodialysis was associated with a significant decrease in detectable immune complexes which, in turn, was associated with improvement and stabilization of renal function. We suggest that hemodialysis may remove immune complexes from the circulation and that it could be of therapeutic benefit in selected patients with presumed immune complex-mediated glomerulonephritis.

Application of the solid phase C1q and Raji cell radioimmune assays for the detection of circulating immune complexes in glomerulonephritis.

The C1q solid phase and Raji cell radioimmune assays were used to determine the frequency of detectable circulating immune complexes in patients with glomerulonephritis. In this study, 46% of 56 patients with glomerulonephritis had evidence of circulating immune complexes. More important, circulating immune complexes were associated with some, but not other, types of glomerulonephritis. Thus, immune complexes were detected in lupus glomerulonephritis (9/9 patients), rapidly progressive glomerulonephritis (5/6 patients), and acute nephritis (5/6 patients), but not in IgA-IgG glomerulonephritis (0/7 patients), or membranous glomerulonephritis (0/8 patients). The Raji cell radioimmune assay and the C1q solid phase radioimmune assay showed concordance of 79% in the detection of circulating immune complexes. Serial determinations, in general, showed either persistence of a negative or positive result of conversion of positive to negative.

Circulating immune complexes in disseminated gonorrheal infection.

Circulating immune complexes were detected by the Raji-cell radioassay or the C1q solid-phase assay in 13 of 17 patients with disseminated gonococcal infection. In contrast, only three of 20 patients with local gonococcal infection and four of 40 normal persons were positive. The immune complexes were found to be 19S or larger in size, and complement abnormalities suggestive of complement activation showed some correlation with the levels of immune complexes in disseminated gonorrheal infection. These results indicate that in addition to bacterial dissemination, circulating immune complexes may be involved in the pathogenesis of disseminated gonococcal syndrome.

Antacid-induced hypophosphatemia: an unusual cause of "pseudo-myopathy".

A 69 year old man presented with painful proximal muscle weakness which clinically simulated polymyositis. Further evaluation revealed normal muscle enzymes and hypophosphatemia which resulted from unsuspected antacid abuse. "Pseudo-myopathy" is one example of the myriad of rheumatic diseases which may be mimicked by hypophosphatemia.
