RESUMEN
Objective: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly around the world, and COVID-19 and HIV co-infection also became common. In this study, we aimed to investigate the impact of vaccination preferences and vaccination rates on the severity of COVID-19 in patients with HIV co-infection. Materials and Methods: People living with HIV who were followed in our hospital during the COVID-19 pandemic (January 2020- December 2022) were retrospectively included in the study. The diagnosis of COVID-19 was made by detecting SARS-CoV-2 RNA in nasopharyngeal swab specimens using real-time reverse transcriptase-polymerase chain reaction (rRT-PCR). Patients requiring hospital admission were classified as severe. The patient's demographics and vaccination status were collected from the hospital data system. Results: Our study included 205 patients using antiretroviral therapy for HIV. The mean day count between the last vaccine date and SARS-CoV-2 PCR positivity was 163 days in the Comirnaty® group,149 days in the CoronaVac® group, and 154 days in the mixed-vaccinated group. Those vaccinated with Comirnaty® were statistically significantly less infected with COVID-19 after vaccination (p<0.05). Conclusion: The course and the outcomes of COVID-19 among SARS-CoV-2 vaccinated people living with HIV, especially with well-controlled HIV infection, seem to be similar to people living without HIV.
RESUMEN
OBJECTIVE: As known, older age and comorbidities are associated with poor clinical outcomes in patients with coronavirus disease 19. The aim of this study was to investigate the effect of the Charlson Comorbidity Index in predicting poor clinical outcomes in coronavirus disease 19 patients. MATERIAL AND METHODS: Demographic characteristics and poor clinical outcomes (presence of pneumonia, respiratory failure, intensive care unit admission, and mortality) of the patients were evaluated retrospectively. Classical and modified Charlson Comorbidity Index was calculated and adjusted according to age. RESULTS: In this study, 106 women and 107 men were included. The comorbidity rate was 50.7% and the most common comorbidities were hypertension (21.6%) and diabetes mellitus (15%). The rates of respiratory failure, intensive care unit admission, and mortality were 15%, 2.3%, and 2.8%, respectively. Older age was a high risk for poor outcomes. Pneumonia (odds ratio: 6.6; 95% CI: 3.4-12.7), respiratory failure (odds ratio: 5.2; 95% CI: 2.03-13.2), and intensive care unit admission (odds ratio: 1.1; 95% CI: 1.01-1.1) were significantly higher in patients with comorbid diseases than patients without any comorbidity (P < .05). Both median-modified and classical Charlson Comorbidity Index and their age-adjusted scores were significantly higher in patients with poor outcomes. CONCLUSIONS: It is suggested that evaluation of the Charlson Comorbidity Index might contribute to the management of the patients with coronavirus disease 19 by predicting risk group for poor clinical outcomes and mortality.
