Patterns of HIV and SARS‐CoV‐2 co‐infection in Wuhan, China

People living with HIV/AIDS (PLWHA) were initially considered to be at an increased risk of infection with SARS‐CoV‐2 due to their risk of immunosuppresion [1]. However, few studies have reported on co‐infections between HIV and SARS‐CoV‐2 and treatment outcomes, and data to date do not support either increased acquisition or severity of COVID‐19 [2, 3]. Here we present the clinical and laboratory patterns in 14 co‐infected cases, including three asymptomatic SARS‐CoV‐2 carriers in Wuhan, China, from 16 February to 30 April 2020.

The 14 cases were coded P1 to P14 in order of their infection severity, namely: critical (P1 and P2), severe (P3 to P5), mild (P6 to P11) and asymptomatic (P12 to P14) (Table 1). The case group consisted of 13 men who have sex with men (MSM) and one heterosexual female. Only P10 and P13 had smoking history, and none of them abused alcohol.

The median age of the COVID‐19 patients was 56 (range 31 to 71 years old), whereas the three SARS‐CoV‐2 carriers were 24, 57 and 64 years old. Five patients had hypertension and were on anti‐hypertensive agents.

Ten patients and two asymptomatic carriers showed undetectable HIV viral load (HIV‐VL) and CD4⁺ T lymphocyte count (CD4 count) between 141 to 817/µL prior to SARS‐CoV‐2 co‐infection. Two HIV‐VL unsuppressed individuals included patient (P5) who presented with a CD4 count of 34/µL without having ever received antiretroviral therapy (ART), and an asymptomatic carrier (P12) who presented with a CD4 count of 29/µL after two weeks of ART. Four co‐morbidity cases presented with a CD4 count less than 200/µL, including two severe cases and two mild cases (All recovered at the end of the study). Although P12 presented with a low CD4 count, he did not even show any symptoms of COVID‐19 or any abnormality in the radiograph. This may indicate that low CD4 count did not inevitably lead to death under HIV and SARS‐CoV‐2 co‐infection. On the contrary, the two deaths occurred in cases who had a relatively high CD4 count (350/µL and 695/µL). This finding is consistent with a previous study, which reported one AIDS/COVID‐19 patient who presented a low CD4 count (13/µL) and recovered finally [2]. Considering that SARS‐CoV‐2 might cause multi‐organ injury through the inflammatory cytokine storm [4], we hypothesized that previous low CD4 count might act a protective role in preventing hyperimmune response. However, our sample size limits the deduction for a generalized conclusion, and hence large‐scale investigation is needed to validate this hypothesis.

The proportion of severe cases (5/11, 45.5%) was higher among the case series than reported in the general population [5]. The COVID‐19 mortality rate (18.2%) was also higher than the overall COVID‐19 mortality (7.7%, 3869/50333) in Wuhan [6]. The median age among the co‐infected cases was older than that of overall patients, and the higher proportion of comorbidities in our patients (8/11, 72.7%) coupled with the senior age might have contributed partially to the higher proportion of severe case and mortality. Living with HIV/AIDS also played a role in leading to comorbidities prior to admission, such as lymphoma and opportunistic infection (pneumocystis pneumonia, PCP).

Reports from laboratory examinations at admission showed leukopenia in six cases and lymphopenia in discrepant six cases. Although the exact immune‐pathogenesis of the decrease in lymphocytes in peripheral blood remains unclear, lymphopenia is also reported as a frequent presentation in HIV negative COVID‐19 patients, especially in severe cases [5, 7]. The pattern of immune cells in AIDS/COVID‐19 patients showed minor differences from that of overall COVID‐19 patients [8]. However, patients’ CD4 count, HIV‐VL and inflammatory cytokines were not tested on the admission, which prevented us from knowing more about the immune status at the early stage of SARS‐CoV‐2 infection in PLHWA. Another limitation should be mentioned that only one ART naïve COVID‐19 case was enrolled in our investigation, although knowing the COVID‐19 prognosis in ART naïve patients is critical. However, together with the case series published earlier [3], the previous immune status and the clinical course of all the patients in this study still help to sum up some experiences in treating COVID‐19 in PLWHA.

The COVID‐19 pandemic has had a significant impact on people around the world, including PLWHA, and continues to grow. Health facilities should endeavour to maintain undisputed antiretroviral supply to PLWHA during the pandemic phase to ensure retention in care and treatment success. Co‐infected patients who presented with low CD4 count and high HIV‐VL, as well as opportunistic infections, should be considered for active treatments as they still have a chance to recover by proper treatment.
