Cryoglobulins are associated with chronic infections.
To investigate the prevalence of mixed cryoglobulinemia in patients with HIV-1 infection, the clinical spectrum of cryoglobulinemia in these patients, and the possible role of HIV-1 in cryoglobulin formation.
Prospective cohort study.
Laiko Hospital, Athens, Greece.
89 patients with HIV-1 infection.
Serum and cryoglobulins were evaluated for antibodies to HIV and hepatitis C virus (HCV), HIV-1, and HCV viral load.
Mixed cryoglobulins were detected in 24 patients with HIV-1 infection (27% [95% CI, 18% to 36%]). The HIV-1 viral load was higher in cryoglobulin-positive patients (median, 38.25 × 103 copies/mL [25th, 75th percentiles: 13.8 × 103 copies/mL, 78.55 × 103 copies/mL]) than in cryoglobulin-negative patients (median, 5.3 × 103 copies/mL [25th, 75th percentiles: 0.7 × 103 copies/mL, 27.2 × 103 copies/mL]) (P = 0.001). Antibodies to HIV were detected in all cryoprecipitates, and HIV-1 RNA sequences were identified in 22 of the 23 cryoprecipitates examined. Nine cryoglobulin-positive patients (38% [CI, 19% to 54%]) had clinical manifestations compatible with cryoglobulinemia.
Mixed cryoglobulinemia is common in patients with HIV-1 infection.
