ABSTRACT

BACKGROUND: While existing research on people living with HIV (PWH) during the COVID-19 pandemic primarily focused on their clinical outcomes, a critical gap remains in understanding the implications of COVID-19 delivery of in-hospital care services to PWH. Our study aimed to describe the characteristics and outcomes of PWH hospitalised during 2020 in Mexico City, comparing patients admitted due to COVID-19 vs. patients admitted due to other causes. METHODS: All PWH hospitalised for ≥ 24 h at four institutions in Mexico City from January 1st to December 31st, 2020 were included. Patients were classified into two groups according to the leading cause of their first hospitalisation: COVID-19 or non-COVID-19. Characteristics among groups were compared using chi-square and Kruskal tests. A Cox model was used to describe the risk of death after hospitalisation and the characteristics associated with this outcome. Mortality and hospitalisation events were compared to data from 2019. RESULTS: Overall, we included 238 PWH hospitalised in 2020. Among them, 42 (18%) were hospitalised due to COVID-19 and 196 (82%) due to non-COVID-19 causes, mainly AIDS-defining events (ADE). PWH hospitalised due to COVID-19 had higher CD4 + cell counts (380 cells/mm3 [IQR: 184-580] vs. 97 cells/mm3 [IQR: 34-272], p < 0.01) and a higher proportion of virologic suppression (VS) compared to those hospitalised due to non-COVID-19 causes (92% vs. 55%, p < 0.01). The adjusted hazard ratio (aHR) for AIDS was 3.1 (95%CI: 1.3-7.2). COVID-19 was not associated with death (aHR 0.9 [95%CI: 0.3-2.9]). Compared to 2019, mortality was significantly higher in 2020 (19% vs. 9%, p < 0.01), while hospitalisations decreased by 57%. CONCLUSIONS: PWH with COVID-19 had higher VS and CD4 + cell counts and lower mortality compared to those hospitalised due to non-COVID-19-related causes, who more often were recently diagnosed with HIV and had ADEs. Most hospitalisations and deaths in 2020 in PWH were related to advanced HIV disease. The increased mortality and decreased hospitalisations of PWH during 2020 evidence the impact of the interruption of health services delivery for PWH with advanced disease due to the pandemic. Our findings highlight the challenges faced by PWH during 2020 in a country where advanced HIV remains a concern.

ABSTRACT

The epidemiology of lymphomas has changed since the use of antiretroviral therapy. The incidence of Non-Hodgkin Lymphomas (NHL) has significantly decreased in high income countries but not in low and middle-income countries where AIDS-related events remain high. This observational study describes the characteristics, infectious complications and main outcomes of patients diagnosed with HIV and lymphoma at the Instituto Nacional de Cancerología.All adults >18 years diagnosed with HIV and lymphoma from January 2010 to December 2017 were included. Information on HIV and lymphoma was collected, as well as the occurrence of co-infections at diagnosis and during therapy. Multiple regression was done with NHL patients to evaluate independent variables associated to death.One hundred fifty three patients were included: 127 patients with NHL (83%) and 26 (17%) with Hodgkin lymphoma (HL). Of the NHL, 49 (38%) were diffuse large B cell Lymphomas (DLBCL), 35 (27%) plasmablastic, 28 (23%) Burkitt, 10 (8%) primary DLBCL of Central Nervous system, 3 (2%) T-cell lymphomas, and 2 (2%) pleural effusion lymphoma. Most patients were diagnosed in an advanced stage: 70% of NHL had a high International Prognostic Index (IPI); 68% of patients had <200 cells/mm. Almost 25% of NHL patients had an opportunistic infection at lymphoma diagnosis. During chemotherapy, 60% of all patients presented with at least 1 serious non-opportunistic infectious complication, and 50% presented 2 or more infectious complications, mostly bacterial infections. Thirty six percent of NHL and 23% of HL died. After adjusting for confounders, the variables associated with death were IPI and lymphoma type.HIV positive patients with lymphoma in our institution are diagnosed with an advanced stage and a high burden of infections complications. Death remains high and the variables strongly associated with death are those related to lymphoma prognosis such as lymphoma type and IPI.
