Abstract

Purpose To evaluate the rates of new-onset cytomegalovirus (CMV) retinitis and worsening existing CMV retinitis in patients with AIDS after initiating combination antiretroviral therapy (cART) and the role of an immune recovery inflammatory syndrome (IRIS). Design Cohort study. Methods Immune recovery was defined as an increase in CD4+ T cells to ≥100 cells/μL; rates of new-onset CMV retinitis and of worsening of CMV retinitis (either increasing border activity or retinitis progression) were compared between those with and without immune recovery. Results Among patients without CMV retinitis, 1 of 75 patients with immune recovery developed CMV retinitis in the first 6 months after initiating cART vs 1 of 31 without immune recovery (P =.14). Among patients with CMV retinitis, the rates of retinitis progression and increasing retinitis border activity among patients during the first 6 months after initiating cART in those with immune recovery were 0.11 per person-year (PY; 95% confidence interval [CI] 0–0.62) and 0.11 per PY (95% CI 0–0.62), respectively, vs 0.67 per PY (95% CI 0.22–1.56) and 0.40 per PY (95% CI 0.08–1.17), respectively, for those without immune recovery (P =.11 and .47). Conclusions Among persons with AIDS who experience immune recovery, there was neither an increased rate of new-onset CMV retinitis nor worsening of existing CMV retinitis in the first 6 months after initiating cART vs those without immune recovery. These data are consistent with the known 3- to 6-month lag in recovery of specific immunity to CMV after initiating cART and suggest that “immune recovery retinitis,” a proposed immune recovery inflammatory syndrome phenomenon, is rare.
