METHODS: Maximum body temperatures, fever duration, chest CT and viral shedding, lymphocyte counts, and titer of SARS-CoV-2 antibody were compared between COVID-19 patients with and without HIV infection in Zhongnan Hospital of Wuhan University from January 20th to February 14th, 2020. RESULTS: Compared with 53 COVID-19 patients without HIV infection, the patients with SARS-CoV-2 and HIV coinfection had higher maximum body temperatures (38.7°C vs 37.6°C, P = 0.044), longer duration of fever (8.7 ± 4.5 vs 4.2 ± 2.1 days, P = 0.038), longer time to have improvement of chest CT images (22 vs 15 days from the onset of illness, P = 0.011), lower level of SARS-CoV-2 IgG (5.11 ± 32.33 vs 37.45 ± 15.48 AU/ml, P = 0.042). However, no statistically significant difference of duration of SARS-CoV-2 shedding in the two groups was found (12.3 ± 2.6 vs 13.4 ± 2.4 days, , P = 0.813). CONCLUSION: Lower level of CD4(+) T lymphocyte counts caused by HIV infection itself might be one of reasons for relatively weak ability to produce SARS-CoV-2 specific antibodies. The effects of anti-HIV drugs in prevention and treatment of COVID-19 appears to be limited. COVID-19 is a public health emergency that is spreading worldwide and seriously affecting global economy [1] [2] [3] [4] [5] . There are currently no drugs available to inhibit SARS-CoV-2 replication. Due to the limited experience of combination of lopinavir, ritonavir and interferon beta (LPV/RTV-IFNβ) in the treatment of MERS [6, 7] , the question of whether or not anti-HIV drugs can play a role in the the prevention and treatment of COVID-19 has been drawn attention by public [8] . In China, the permanent resident population was 1.4 billion. The number of people living with HIV/AIDS is approximate one million and the recently reported patients with COVID-19 is 85 thousand [9, 10] . Wuhan was a high incidence of COVID-19 in the early stages of the epidemic, but the number of patients with SARS-CoV-2 and HIV infection is still limited. In this background, limited information on COVID-19/HIV coinfection patients were showed and analyzed in this study, in order to provide clinical clues for future prospective studies. The patients confirmed with COVID-19 and HIV infection were hospitalized to Zhongnan Hospital of Wuhan University from January 20th to February 14th. Among COVID-19 patients who were hospitalized during the same period, those patients with same gender and age were used as control groups. This retrospective study was approved by the ethics committee of Zhongnan Hospital of Wuhan University (No. 2,020,011). Informed written consent was waived by the Ethics Commission of Zhongnan Hospital of Wuhan University in consideration of the retrospective nature of the study and the urgency of reporting on emerging infectious diseases. COVID-19 was confirmed by detecting SARS-CoV-2 RNA in throat swab samples using a virus nucleic acid detection kit according to the manufacturer's protocol (Shanghai BioGerm Medical Biotechnology Co.,Ltd). Briefly, the RT-PCR assay for SARS-CoV-2 amplifies simultaneously two target genes: open reading frame 1ab (ORF1ab) and the ORF for the nucleocapsid protein (N). Target 1 (ORF1ab): forward primer CCCTGTG GGTTTTACACTTAA; reverse primer ACGATTGTGCATCAGCTGA; probe 5ʹ-VICCCGTCTGCGGTATGTGGAAAGGTTATGG-BHQ1-3ʹ. Target 2 (N): forward primer GGGGAACTTCTCCTGCTAGAAT; reverse primer CAGACATTTTGCTCTCAAGCTG; probe 5ʹ-FAM-TTGCTGCTGCTTGACAGATT-TAMRA-3ʹ. Positive (pseudovirus with a fragment of ORF1ab and N) and negative (pseudovirus with a standard fragment) quality control samples were tested simultaneously. A cycle threshold (Ct) value of less than 37 was defined a positive test, while a Ct value of more than 40 was defined as a negative test. For the cases with an intermediate Ct value (37-40), a second sample was tested and weakly positive was defined as a recurrence of Ct value of 37-40. The diagnostic criteria were based on the recommendation from the National Institute for Viral Disease Control and Prevention (China) [111213]. The following information, such as age, gender, COVID-19related exposure history, symptoms, signs, severity assessment on admission, laboratory findings, and chest CT findings were collected. The data were reviewed by a trained team of physicians. All statistical analyses were performed using GraphPad Prism 8.0.2 software. The comparison of highest body temperature, duration of fever and lung recovery, and levels of SARS-CoV-2 specific antibodies, changes of lymphocyte and CD4 + T lymphocyte counts were used independent group t tests. P < 0.05 was considered statistically significant. The selection of 56 COVID-19 patients in this study was shown in Figure 1 . There were three patients with COVID-19 and HIV coinfection, and the other 53 COVID-19 patients without HIV infection were analyzed as control group. All the three patients with COVID-19 and HIV coinfection were male and receiving ART therapy, and the patients in control group were comparable in gender and age. Their baseline characteristics, such as fever, lymphocyte count, CD4 + T lymphocyte counts and chest CT manifestation, were compared in Table 1 . • HIV coinfection does not affect the diagnosis and clinical typing of COVID-19. • Patients coinfection with SARS-CoV-2 and HIV had longer duration of fever and lung imaging recovery. • Lymphocytopenia associated with SARS-CoV-2 infection can return to normal along with the improvement of the disease, which is different from lymphocytopenia caused by HIV infection which requires ART for a long time to recovery. • No statistically significant difference in the duration of SARS-CoV-2 shedding was found between COVID-19 patients with and without HIV coinfection in this study. • For HIV-infected patients with severe immune deficiency, the ability to produce SARS-CoV-2 antibodies could also be weakened. In Chest CT images of the three patients with SARS-CoV-2 and HIV coinfection were shown in Figure 3 . Two of them showed typical clinical and radiological manifestations on admission while chest CT manifestation of the third patient showed no abnormalities. Table 2 . Cases of COVID-19/HIV coinfection were not common until now. Although a few of studies involving patients with SARS-CoV-2 In this study, even if COVID-19 patients coinfected with HIV, they have symptoms and imaging manifestations of typical viral pneumonia [1] , or they are asymptomatic SARS-CoV-2 carrier, which suggesting that HIV coinfection does not affect the diagnosis and clinical typing of COVID-19. Fever and cough are the initial symptoms and primary cause of hospitalization for most COVID-19 patients [16] . Compared with COVID-19 patients without HIV infection, except for the highest body temperature, those patients with COVID-19 and HIV coinfection had longer duration of fever and lung imaging recovery. We hypothesized that the delayed SARS-CoV-2 specific antibody response caused by HIV infection may affect the recovery of lung lesions, but this hypothesis needs to be confirmed by in-depth randomized controlled observation. In terms of blood test indicators, lymphocytopenia is one of the characteristics of advanced stage of AIDS after HIV infection. Meanwhile lymphocytopenia is common among COVID-19 patients [17] . In this study, the levels of lymphocyte counts in COVID-19 patients without HIV infection returned to normal in later stage of the disease, but persistently lymphocytopenia was common in patients with COVID-19 and HIV infection throughout the observation period. The target cells for HIV infection are CD4 + T lymphocyte cells. As a component of lymphocyte subsets, the changes of CD4 + T lymphocyte counts can affects the level of total lymphocyte counts. For patients with COVID-19 and HIV infection, we hypothesized that, both the extremely low CD4 + T lymphocyte cells levels and the persistent lymphocytopenia after recovery from COVID-19 were associated with immunodeficiency by HIV infection itself. Moreover, we can preliminarily speculate that the lymphocytopenia associated with SARS-CoV-2 infection can return to normal along with the improvement of the disease. This is different from the lymphocytopenia caused by chronic HIV infection which requires ART for a long time to recovery. In generally, it is difficult to obtain an effective treatment options during a short time of the outbreak of a new emerging viral diseases. As such, treatments designed and approved for other diseases are administered to patients with emerging viral syndromes empirically based on limited clinical or laboratory data. By referring the limited experience on Middle East respiratory syndrome coronavirus (MERS-CoV) treatment [6] , a combination of lopinavir, ritonavir and interferon beta (LPV/RTV-IFNβ) is speculated to be valid for severe COVID-19 patients. This has led to speculation about the use of anti-HIV drugs to treat COVID-19. However, no statistically significant difference in their duration of SARS-CoV-2 shedding from the onset of symptoms was found between COVID-19 patients with and without HIV coinfection in this study. Although we cannot confirm or exclude the same incubation period between the two groups, we speculated that the anti-HIV drugs taken by patients with COVID-19 and HIV coinfection in this cluster failed to shorten the duration of SARS-CoV -2 shedding. In addition, all COVID-19/HIV coinfection patients in this study acquired SARS-CoV-2 infection during ART process, suggesting that anti-HIV drugs have limited effect on the prevention of SARS-CoV-2 infection. Of course, to draw the final conclusion, systematical observations are needed by comparing the SARS-CoV-2 infection rate in patients with ART and without ART under the same exposure environment. Lymphocytes can play an important role in the maintenance of immune system function [18] . In this study, both on admission and after pulmonary symptoms recovery, the level of CD4 + T lymphocyte counts of patients with COVID-19 and HIV coinfection was lower than that of the COVID-19 patients without HIV infection. Moreover, the level of SARS-CoV-2 IgG was found to be lower in patients with COVID-19 and HIV coinfection. We speculated that the low level of CD4 + T lymphocyte counts in HIV coinfection group might be one of the reasons for the relatively weak ability to produce antibodies. In view of the previous reports about hepatitis B vaccination in HIV-infected patients, it was found that the lower the CD4 + T lymphocyte count, the lower proportion of patients to acquire protective HBsAb [19] [20] [21] [22] [23] . Therefore, as for those HIV-infected patients with severe immune deficiency, we speculated that their ability to produce SARS-CoV-2 antibodies could also be weakened. As for this particular population of HIV infection, the impact of CD4 + T lymphocyte counts on SARS-CoV-2 antibodies screening results should be taken into account, when conducting an epidemiological investigation of COVID-19 herd immunity. There are some limitations in this study. First, the number of patients with COVID-19/HIV coinfections is limit. The situation of COVID-19/HIV coinfection did not receive enough attention in the early stage of COVID-19 outbreak. As far as we know, the total number of reported patients with SARS-CoV-2 and HIV coinfection is 142 cases all over the world [24] . Second, the three patients with COVID-19/HIV coinfection and the control group reported in this study were all male, which could not fully reflect the clinical characteristics of the overall population. A recent review reported that, of those patients with COVID-19 and HIV coinfection, 84.5% were male [24] , which was consistent with the situation that all the three cases in this study were male. Future research on the effects of immunodeficiency on COVID-19 can be expanded to follow the clues provided in this study. For COVID-19 patients coinfected with HIV coinfection, their highest body temperature were higher, and they had longer duration of fever and lung imaging recovery. Their lower level of CD4 + T lymphocyte counts caused by HIV infection itself might be one of the reasons for the relatively weak ability to produce SARS-CoV-2 specific antibodies. The effects of anti-HIV drugs in prevention and treatment of COVID-19 appears to be limited, but larger sample size of systematic observations are needed to draw conclusions. The authors present an interesting report on COVID-19 in HIV positive patients. Compared to 50 COVID-19 cases, the authors report that the co-infections were characterized by higher and longer duration fever. They also took longer to recover from their lung disease. Their lung lesions took additional days to resolve. This report, although limited by the low number of subjects, will add clinical insights to the literature, which will be needed for future studies.
