AB To get a measure of the extent of induction of nitric oxide synthase in
infection with human immunodeficiency virus type-1 (HIV-1) in vivo, we
estimated serum nitrite plus nitrate concentrations in 110 HIV-1
infected individuals compared to 76 blood donors. To monitor cytokine
action and to measure induction of pteridine synthesis, we determined in
parallel neopterin, biopterin, soluble tumor necrosis factor-alpha
receptor 55 and 75, and beta 2-microglobulin. Serum nitrite plus nitrate
concentrations were elevated in patients as compared to blood donor
controls. In sera of patients, nitrite plus nitrate levels correlated
significantly with neopterin, soluble tumor necrosis factor receptor 55
and 75, and beta 2-microglobulin. Nitrite plus nitrate levels were
higher and correlations were stronger in groups of patients with lower
CD4+ cell count. These results suggest that cytokine-mediated nitric
oxide synthesis occurs in individuals with HIV-1 infection.
