Abstract The date about the condition of HBV co infection with the disease progress of HIV is limited. To investigate whether the incidence of HBV co-infection is significantly higher in HIV patients with disease progression in China, we compared rates of HBV co-infection in HIV patients based on an acute and a chronic HIV infected cohort. Significance was assessed with Chi-square. HBV infection is diagnosed by the presence of hepatitis B surface antigen. The HBsAg positive rate increased from 6.18% in acute HIV infection to 11.44% in chronic HIV infection. Thirty-four acute HIV patients had been tested for HBV in their chronic phase, four of them had HBV -specific antigens and/or specific antibodies changes. The number of Hepatitis B virus-specific antibodies decreased from acute phase to chronic phase in four patients and two patients’ HBsAg changed from negative to positive. There is an increased prevalence of HBV infection in HIV patients with the disease progression in China.

ABSTRACTAntiretroviral therapy (ART) during acute HIV infection (AHI) interrupts viral dynamics and may delay the emergence of serological markers targeted by current HIV screening and confirmatory assays, thus creating challenges for correctly classifying HIV infection status. The performance of three HIV antigen/antibody combination (HIV Ag/Ab Combo) assays (the Bio-Rad GS, Abbott Architect, and Bio-Rad BioPlex 2200 assays) was evaluated with samples collected from RV254/South East Asia Research Collaboration in HIV 010 (RV254/SEARCH010) study (Bangkok, Thailand) participants at weeks 12 and 24 following the initiation of ART at Fiebig stage I (FI) (n = 23), FII (n = 39), or FIII/IV (n = 22). Supplemental, confirmatory testing was performed by the Geenius HIV 1/2 and HIV-1 Western blot assays (Bio-Rad). Samples from 30 untreated, HIV-1-infected individuals demonstrated robust HIV Ag/Ab Combo assay reactivity with well-developed HIV-1 Western blotting profiles by 24 weeks after infection. In contrast, 52.2% of samples from individuals initiating ART at FI, 7.7% of samples from individuals initiating ART at FII, and 4.5% of samples from individuals initiating ART at FIII/IV were nonreactive by the HIV Ag/Ab Combo assays, with 36.4 to 39.1% of samples having low signal-to-cutoff (S/CO) results by the Architect and BioPlex assays (S/CO < 10). Seroreversion from a reactive to a nonreactive status was observed in 10 individuals initiating ART at FII and 3 individuals initiating ART at FIII/IV. The Geenius and HIV-1 Western blot assay results were negative or indeterminate for 73.9% and 69.6% of individuals, respectively, treated at FI; 50.0% and 26.3% of individuals, respectively, treated at FII; and 54.5% and 40.9% of individuals, respectively, treated at FIII/IV. Virologic suppression of HIV-1 by ART during AHI impedes seroconversion to biomarkers of infection, limiting the utility of HIV Ag/Ab Combo and supplemental, confirmatory assays for infection status determination.

Abstract Background Among acute HIV infection （AHI）and chronic HIV infection（CHI）,the association of HIV-1 DNA and HIV-1 RNA is currently a hot spot of concern. We studied HIV-1 DNA levels in patients with AHI and CHI before initiation of ART to explore the growth characteristics of the HIV reservoir. Methods From 2016/10/31 to 2020/11/23, 97 patients were enrolled in the first hospital of Changsha in China. According to the patient’s epidemiological history, HIV-1 antibody conversion time, presence of opportunistic infection（OI）, to determine whether the patients were in the acute or chronic infection period, and divided into two arms: AHI and CHI. Lleukomonocyte, HIV-1 RNA, and CD4/8 of all patients were collected. The HIV-1 DNA in peripheral blood mononuclear (PBMC) was detected by PCR-Fluorescence Probing. The results were analyzed by SPSS 22.0 and GraphPad Prism 8.0. P-value &lt; 0.05 were statistically significant. Results 93 of 97 were male and 85 of 97 with sexual transmission. In AHI arm, the mean of HIV-1 RNA was 5.15 log10 copies/ml, and the mean of HIV-1 DNA was 2.83 log10 copies/106 PBMCs. In CHI Arm, the mean value of HIV-1 RNA was 4.90 log10 copies/ml, and the mean value of HIV-1 DNA was 3.19 log copies/106 PBMCs. The HIV-1 DNA of CHI group was higher than that of AHI group (p = 0.002) , but the HIV-1 RNA of CHI group was lower than that of AHI Group (p = 0.183) . There were no significant differences between AHI and CHI in age, sex, body weight, route of infection, ART, other viral infection, leukomonocyte, CD4+ T cell count, CD4+ T cell percentage, CD8+ T cell count, CD8+ T cell percentage and CD4/CD8 ratio (P &gt; 0.05).In Group AHI, HIV-1 DNA was positively correlated with HIV-1 RNA (r = 0.548, p &lt; 0.001), but not in Group CHI (r = 0.14, p = 0.347). Conclusion Patients with AHI have lower HIV-1 DNA levels and smaller viral reservoir than those with CHI. These data have illustrates the benefits of rapid treatment. The correlation between HIV-1 DNA and HIV-1 RNA in patients with acute infection is strong,the level of HIV-1 DNA increased with the increase of HIV-1 RNA level, but was not related to CD4 + T cells, CD8 + T cells and CD4/CD8 ratio.

Radical Damage

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme defect described in humans. Hemolysis in affected patients is usually triggered by circumstances involving free radical damage. While acute HIV infection is known to be a state of overwhelming oxidative stress, virus-induced hemolytic events in G6PD-deficient patients has rarely been reported. Despite an estimated overall prevalence of 6.8%–13% of this disorder in the HIV population, clinically significant hemolysis has been largely attributed to the use of offending medications rather than HIV infection itself. Here, we present a patient whose first episode of G6PD deficiency-associated hemolysis occurred as the main presentation of acute HIV infection.

Chronic Hiv Infection

A hallmark of HIV-1 infection is chronic inflammation, which plays a significant role in disease pathogenesis. Acute HIV infection induces robust inflammatory responses, which are insufficient to prevent or eliminate virus in mucosal tissues. While establishment of viral set-point is coincident with downregulation of acute innate responses, systemic inflammatory responses persist during the course of chronic HIV infection. Since the introduction of combination antiviral therapy (cART), most HIV-1+ individuals can suppress viremia under detection levels for decades. However, chronic immune activation persists and has been postulated to cause HIV associated non-AIDS complications (HANA). Importantly, inflammatory cytokines and activation markers associated with macrophages are strongly and selectively correlated with the incidence of HIV-associated neurocognitive disorder (HAND), cardiovascular dysfunctions (CVD) and other HANA conditions. In this review, we discuss the roles of macrophages in facilitating viral persistence and contributing to generation of persistent inflammatory responses.
