- AIDS-related cytomegalovirus encephalitis in the late ART era: A retrospective cohort study at a referral center in Brazil(2023) LUCAS JUNIOR, Rodovaldo M.; BOGONI, Giuliane; SCHNEIDER, Gustavo A. Reis; SOUZA, Nidyanara F. Castanheira de; CARVALHO, Maria Kassab; VIDAL, Jose ErnestoBackground AIDS-related cytomegalovirus (CMV) encephalitis has declined in the combined antiretroviral therapy (ART) era in high-income countries. However, there is scarce information on CMV encephalitis in low- and middle-income countries. The objectives of this study were to identify the prevalence of AIDS-related CMV encephalitis and describe its main features. Methods This was a retrospective cohort study carried out at a referral center in Sao Paulo, Brazil. We included adult people living with HIV/AIDS (PLWHA), hospitalized in 2019, with a CD4 cell count <= 100/mm(3) and quantitation CMV DNA results in plasma. Cases with compatible neurological manifestations and detection of CMV DNA by polymerase chain reaction (PCR) in cerebrospinal fluid samples were defined as CMV encephalitis. Results Among 761 PLWHA hospitalized, 248 (32.5%) cases were included in this study. Prevalence of CMV encephalitis was 2.4% (6/248) among all included cases and 7.7% (6/78) among individuals with neurological opportunistic diseases. The six patients with CMV encephalitis were males and had CD4 cell count <50/mm(3). Five (83%) cases had CMV encephalitis as AIDS-defining disease and showed CMV DNA detection by PCR >500,000 UI/mL plasma. All six cases received anti-CMV therapy (ganciclovir, n = 4; ganciclovir plus foscarnet, n = 2) and five were discharged to home. CMV encephalitis was not uncommon among hospitalized PLWHA with neurological opportunistic diseases. Conclusions The epidemiological and immunological profile of individuals with CMV encephalitis was similar to that described in the pre-ART era, but in contrast, most cases were treated and discharged from the hospital.
- Cytomegalovirus retinitis in hospitalized people living with HIV in the late antiretroviral therapy era in Sao Paulo, Brazil(2023) BOGONI, Giuliane; LUCAS JUNIOR, Rodovaldo M.; SCHNEIDER, Gustavo Arthur Reis; SOUZA, Nidyanara F. Castanheira de; CARVALHO, Maria Kassab; MARCUSSO, Rosa Maria; VIDAL, Jose ErnestoBackground There is scarce information on AIDS-related cytomegalovirus (CMV) retinitis in middle-income countries. The objectives of this study were to identify the prevalence of active CMV retinitis in severely immunosuppressed people living with HIV (PLWHIV) and to describe its main features. Methods This retrospective cohort study was carried out at a tertiary center in Sao Paulo, Brazil. We included hospitalized adults PLWHIV with CD4 count <= 100 cells/mu L, >= one quantitation of CMV DNA in plasma, and indirect ophthalmoscopy evaluation. Results Thirty-eight (21.6%) of 176 participants had at least an ophthalmoscopy diagnosis and only 3 (1.7%) individuals presented active CMV retinitis. All these participants were male, and retinitis was asymptomatic in 2 cases. Two participants had extraocular end-organ CMV disease and detectable CMV DNA in plasma. Conclusions These results show a low prevalence of active CMV retinitis in the evaluated population. However, 2 of 3 participants had asymptomatic active CMV retinitis and a fifth of participants had at least one ophthalmoscopy diagnosis, suggesting the need for routine ophthalmologic evaluation in hospitalized severely immunosuppressed PLWHIV. The profile of participants with active CMV retinitis was similar to that described in the pre-ART era and quantitation of CMV DNA in plasma was variable.
