Table 1.
Classification of samples being positive, by type of infection.
Table 2.
Characteristics of the study population (for prevalence analysis), and of subpopulations assorted by coinfection with HBV, HCV, and syphilis (containing study participants available for incidence analyses).
Fig 1.
Prevalences of coinfections in MSM of the HIV seroconverter cohort.
The figure shows coinfections with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis. The areas of the ellipses correspond to the calculated proportions of the respective coinfections. White numbers: proportions of respective multiple infections. All percentages are relative to the total number of HIV-positive MSM (N = 1,838). The category “HBV” comprises HIV-positive MSM testing positive for an active, cleared, or occult HBV coinfection; the category “HCV” comprises HIV-positive MSM testing positive for an acute/chronic or cleared HCV-coinfection (for a definition on the basis of the serological testing results of these categories, see Table 1).
Table 3.
Prevalences of hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis in MSM with the HIV-seroconversion cohort, by infection status and age at HIV seroconversion (N = 1,838).
Fig 2.
Incidences of coinfections in MSM of the HIV seroconverter cohort, by time period.
Incidences of hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis infection were calculated per 100 person-years (PY). Whisker graphs show lower and upper limits of calculated 95% confidence intervals. Time under follow-up (number of PY) per infection and time period are indicated below the figure.
Fig 3.
Incidence rate ratios (IRR) of coinfections in MSM of the HIV seroconverter cohort.
IRR for infection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis were calculated for persons living in Berlin and those living elsewhere in Germany and in persons testing positive for syphilis at any time point or and those always testing negative. Whisker graphs show lower and upper limits of calculated 95% confidence intervals.
