People Living with HIV Easily lose their Immune Response to SARS-CoV-2: Result From A Cohort of COVID-19 Cases in Wuhan, China.

ABSTRACT

Background To date, whether the immune response for SARS-CoV-2 infection among people living with HIV(PLWH) is different from HIV-naïve individuals is still not clear. Methods In this cohort study, COVID-19 patients admitted to hospital in Wuhan between January 15 and April 1, 2020, were enrolled. Patients were categorized into PLWH and HIV-naïve group. All patients were followed up regularly (every fifteen days) until November 30, 2020, and the immune response towards SARS-CoV-2 was observed. Results Totally, 18 PLWH and 185 HIV-naïve individuals with COVID-19 were enrolled. The positive conversion rates of IgG were 56% in PLWH and 88% in HIV-naïve patients respectively, and the peak was on the 45th day after COVID-19 onset. However, the positive rate of IgG dropped to 12% in PLWH and 33% among HIV-naïve individuals by the end of the study. The positive conversion rate of IgG among asymptomatic carriers is significantly lower than that among moderate patients (AOR = 0.18, 95% CI 0.05-0.65) and PLWH had a lower IgG seroconversion rate compared to the HIV-naive group (AOR = 0.22, 95% CI 0.05-0.90). Patients with lower lymphocyte counts at onset had a higher positive conversion rate (AOR = 0.29, 95% CI 0.09-0.90) and longer duration for IgG (AHR = 4.01, 95% CI 1.78-9.02). Conclusions The positive conversion rate of IgG for SARS-CoV-2 was relatively lower and quickly lost in PLWH, which meant PLWH was in a disadvantaged situation when affected with COVID-19.
