Comparison of serum and plasma viral RNA measurements in primary and chronic human immunodeficiency virus type 1 infection.
We sought to define the relation between serum and plasma HIV-1 viral RNA load in patients with primary and chronic HIV-1 disease. HIV-1 viral load was determined from 116 serum and plasma samples, including 33 matched pairs, from five patients with primary and three patients with chronic HIV disease using the Roche HIV Monitor assay. The mean +/- standard deviations of the serum and plasma viral RNA levels from the 33 matched pairs were 4.372 +/- 0.885 and 4.478 +/- 0.950 log10 (copies/ml), respectively. This -0.106 log difference between serum and plasma viral RNA levels, which equates to 21% of non-log-transformed values, was not statistically significant by the Wilcoxon sign rank test (p = 0.09). The distributions of serum and plasma viral load slopes, calculated from all available viral RNA load data for each patient, were also not statistically different (p = 0.07). The levels of HIV-1 RNA measured in the serum or plasma of HIV-seropositive patients yield equivalent biologic information.
