RESUMO

To establish a plasma model to predict the risk of liver fibrosis in HIV/HBV co-infected individuals. Quantitative liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to identify differentially expressed proteins (DEPs) in plasma collected from HIV/HBV co-infected individuals with and without liver fibrosis. In total, 97 DEPs were identified, among which 11 were further validated as potential biomarkers, with immunoglobulin and complement components being the most common proteins. These markedly altered proteins were found to mediate pathophysiological pathways, including humoral immune response, complement and coagulation cascades, and complement activation. A visual logistic model, in which immunoglobulin heavy variable 3-20 (IGHV3-20), immunoglobulin heavy variable 1-24 (IGHV1-24), and macrophage colony-stimulating factor 1 receptor (CSF1R) proteins were included, has been established to predict liver fibrosis in HIV/HBV co-infected individuals. The preliminary conclusion showed that the combination of IGHV3-20, IGFHV1-24, and CSF1R is expected to become a predictive model for liver fibrosis in the context of HIV/HBV co-infection and a further validation should be performed.

RESUMO

The identification of circulating proteins associated with acquired immunodeficiency syndrome-related non-Hodgkin lymphoma (AIDS-NHL) may help in the development of promising biomarkers for screening, diagnosis, treatment, and prognosis. Here, we used quantitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify differentially expressed proteins (DEPs) in plasma collected from patients with AIDS-NHL and human immunodeficiency virus (HIV)-infected patients without NHL (HIV+ ). Proteins with a log2 (fold change) in abundance >0.26 and p < 0.05 were considered differentially abundant. In total, 84 DEPs were identified, among which 20 were further validated as potential biomarkers, with immunoglobulin and complement components being the most common proteins. Some of the proteins were further verified in a retrospective analysis of the medical records of patients in a larger cohort. These markedly altered proteins were found to mediate pathophysiological pathways that likely contribute to AIDS-NHL pathogenesis, such as the humoral immune response, complement activation, and complement and coagulation cascades. Our findings provide a new molecular understanding of AIDS-NHL pathogenesis and provide new evidence supporting the identification of these proteins as possible biomarkers in AIDS-NHL.

RESUMO

BACKGROUND: Liver fibrosis is common in individuals with HIV/HBV co-infection, but whether cART could reverses liver fibrosis is unclear. METHODS: This was a retrospective observational study. Binary logistic regression was used to assess predictors of liver fibrosis in individuals with HIV/HBV co-infection. Comparison of FIB-4 scores before and after cART were compared using X2 test and t test. RESULTS: Four hundred and fifty-eight individuals with HIV/HBV co-infection were included in this study. It was found that cART (HR 0.016, 95% CI: 0.009-0.136; P < 0.001) was one of protection factors to against liver fibrosis. Forty individuals who had normal levels of ALT, AST and PLT during the whole course of diseases were stratified into FIB-4 < 1.45 (n = 14), 1.45 ≤ FIB-4 ≤ 3.25 (n = 19) and FIB-4 > 3.25 (n = 7) groups by their FIB-4 scores before cART. In 1.45 ≤ FIB-4 ≤ 3.25 group, 57.9%(11/19) of the individuals dropped to FIB-4 < 1.45 group by cART; in FIB-4 > 3.25 group, 85.7%(6/79) dropped to 1.45 ≤ FIB-4 ≤ 3.25 group, while 14.3%(1/7) dropped to FIB-4 < 1.45 group. In cART-naive group, 1 year, 2-5 years and 5-10 years post-cART groups, FIB-4 scores were 4.29 ± 0.43, 3.63 ± 0.38, 2.90 ± 0.36 and 2.52 ± 0.38, respectively (P = 0.034); and the incidence of liver fibrosis were 7.38%(104/141), 63.6%(98/154), 60.8%(62/102) and 47.5%(29/61), respectively (P = 0.004). CONCLUSION: cART was associated with decreased FIB-4 scores and the benefit of cART in reversing liver fibrosis can sustain for a decade in patients with HIV/HBV co-infection.

RESUMO

The aim of this retrospective study was to observe hepatitis B surface antigen (HBsAg) seroclearance and explore predictors of HBsAg loss in HIV/HBV-co-infected patients receiving long-term lamivudine or both tenofovir and lamivudine containing therapies. Quantification of HBsAg, hepatitis B e antigen and HBV DNA before and after initiation of HBV-active antiretroviral therapy in a total of 268 HIV/HBV-co-infected patients started treatment between 2005 and 2017 were performed. Over a median of 65.63 months of follow-up, 10 (3.7%) were observed HBsAg loss and the quantification of HBsAg in 7 (2.6%) patients were less than 50 IU/mL. With the prolongation of antiretroviral therapy duration time, the rates of HBsAg seroclearance tended to increase gradually, rising from 1.8% (3/163) during 2-4 years treatment to 29.4% (10/34) after antiretroviral therapy for up to 10 years. Lower baseline qHBsAg and HBV DNA levels and strong 12-month declines in qHBsAg were significantly associated with HBsAg seroclearance. The event of HBsAg seroclearance is uncommon among Chinese individuals with HIV/HBV co-infection who have been treated with anti-HBV containing antiretroviral therapy, and lifelong therapy for HBV is needed for HIV/HBV co-infected patients. Baseline qHBsAg and HBV DNA levels and qHBsAg decline rate were predictors for HBsAg seroclearance.

RESUMO

BACKGROUND: The program for the prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) was launched in 2003 in China, but few studies have been conducted to describe the panorama of PMTCT. We investigated the rate and associated factors of mother-to-child transmission (MTCT) in China from 2004 to 2018. METHODS: HIV-infected pregnant women from two areas in China between 2004 and 2018 were enrolled. Antiretrovirals (ARVs) were provided to the mothers and their babies, and the children were followed and tested for HIV. RESULTS: In total, 857 mothers and their 899 children were enrolled, and the overall MTCT rate was 6.6% (95% CI 5.0-8.2). The MTCT rates of nonintervention, only formula feeding (FF), infant prophylaxis (IP) + FF, single dosage antiretrovirals (sdARVs) + IP + FF, zidovudine (AZT) alone+IP + FF and prenatal combination antiretroviral therapy (cART) + IP + FF were 36.4, 9.4, 10.0, 5.7, 3.8 and 0.3%, respectively. The MTCT rate declined over time. No ARVs, CD4 count < 200/µL, low birth weight, and breastfeeding were associated with MTCT of HIV. For different ARVs, a higher MTCT rate was observed for AZT alone, sdARVs, and no ARVs compared to cART for pregnant women. CONCLUSIONS: Although the overall MTCT rate remains relatively high, the real-world effect of prenatal cART+IP + FF in China has exerted the same protective effects in high-income countries. With the extension of prenatal cART for pregnant women with HIV, the MTCT rate of HIV has gradually declined in China. However, the coverage of prenatal cART for pregnant women should be further improved. The effect of only post-exposure prophylaxis for infants was limited.

RESUMO

BACKGROUND: Although antiretroviral therapy (ART) has greatly improved the prognosis of acquired immunodeficiency syndrome (AIDS) patients globally, opportunistic infections (OIs) are still common in Chinese AIDS patients, especially cryptococcosis. CASE PRESENTATION: We described here two Chinese AIDS patients with cryptococcal infections. Case one was a fifty-year-old male. At admission, he was conscious and oriented, with papulonodular and umbilicated skin lesions, some with ulceration and central necrosis resembling molluscum contagiosum. The overall impression reminded us of talaromycosis: we therefore initiated empirical treatment with amphotericin B, even though the case history of this patient did not support such a diagnosis. On the second day of infusion, the patient complained of intermittent headache, but the brain CT revealed no abnormalities. On the third day, a lumbar puncture was performed. The cerebral spinal fluid (CSF) was turbid, with slightly increased pressure. India ink staining was positive, but the cryptococcus antigen latex agglutination test (CrAgLAT: IMMY, USA) was negative. Two days later, the blood culture showed a growth of Cryptococcus neoformans, and the same result came from the skin culture. We added fluconazole to the patient's treatment, but unfortunately, he died three days later. Case two was a sixty-four-year-old female patient with mild fever, productive cough, dyspnea upon movement, and swelling in both lower limbs. The patient was empirically put on cotrimoxazole per os and moxifloxacin by infusion. A bronchofibroscopy was conducted with a fungal culture, showing growth of Cryptococcus laurentii colonies. Amphotericin B was started thereafter but discontinued three days later in favor of fluconazole 400 mg/d due to worsening renal function. The patient became afebrile after 72 h of treatment with considerable improvement of other comorbidities and was finally discharged with continuing oral antifungal therapy. CONCLUSIONS: Our cases illustrate that cryptococcal disease is an important consideration when treating immunocompromised individuals such as AIDS patients. Life threatening meningitis or meningoencephalitis caused by C. neoformansmay still common in these populations and can vary greatly in clinical presentations, especially with regard to skin lesions. Pulmonary cryptococcosis caused by C. laurentii is rare, but should also be considered in certain contexts. Guidelines for its earlier diagnosis, treatment and prophylaxis are needed.

RESUMO

BACKGROUND: CSF PCR is the standard diagnostic technique used in resource-rich settings to detect pathogens of the CNS infection. However, it is not currently used for routine CSF testing in China. Knowledge of CNS opportunistic infections among people living with HIV in China is limited. METHODS: Intensive cerebrospiral fluid (CSF) testing was performed to evaluate for bacterial, viral and fungal etiologies. Pathogen-specific primers were used to detect DNA from cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6) and John Cunningham virus (JCV) via real-time polymerase chain reaction (PCR). RESULTS: Cryptococcal meningitis accounted for 63.0% (34 of 54) of all causes of meningitis, 13.0% (7/54) for TB, 9.3% (5/54) for Toxoplasma gondii. Of 54 samples sent for viral PCR, 31.5% (17/54) were positive, 12 (22.2%) for CMV, 2 (3.7%) for VZV, 1 (1.9%) for EBV, 1 (1.9%) for HHV-6 and 1 (1.9%) for JCV. No patient was positive for HSV. Pathogen-based treatment and high GCS score tended to have a lower mortality rate, whereas patients with multiple pathogens infection, seizures or intracranial hypertension showed higher odds of death. CONCLUSION: CNS OIs are frequent and multiple pathogens often coexist in CSF. Cryptococcal meningitis is the most prevalent CNS disorders among AIDS. The utility of molecular diagnostics for pathogen identification combined with the knowledge provided by the investigation may improve the diagnosis of AIDS related OIs in resource-limited developing countries, but the cost-efficacy remains to be further evaluated.

RESUMO

BACKGROUND: Maternal-infant transmission of hepatitis B virus(HBV) occurs even after passive-active immunization. Some scholars speculate that in-utero infection may be the main cause of immunoprophylaxis failure. However, there is a lack of evidence about the possible occurrence periods of perinatal transmission. METHODS: From 2008 to 2012, 428 pairs of HBsAg-positive mothers and neonates were enrolled and 385 infants aged 8-12 months were followed. HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc, HBV-DNA) were performed on all subjects. RESULTS: Of mothers who were positive for HBsAg, HBeAg, HBV-DNA, 35.1 %, 94.3 %, 12.7 % of their neonates were positive for those indices, respectively. Neonates' mean titers of those indices were significantly lower than their mothers'. There were no significant differences in rates of positivity and mean titers of anti-HBe and anti-HBc between neonates and mothers. Most of the positive indices turned negative during the follow-up period. Immunoprophylaxis failed in seventeen infants: four infants had HBV-DNA > 6 log 10copies/mL both at birth and in follow-up; in six infants, mean viral load was 3.72 ± 0.17 log 10copies/mLat birth and 7.62 ± 0.14 log 10copies/mL at follow-up; seven infants were HBV-DNA negative at birth but were found to have > 6 log 10copies/mL during follow-up. Infants that were immunoprophylaxis failures were all born to HBeAg-positive mothers with HBV-DNA > 6 log 10copies/mL. CONCLUSIONS: The placental barrier can partly prevent maternal HBsAg, HBeAg, HBV-DNA from passing through to fetus. Performing HBsAg, HBeAg, HBV-DNA once at birth can neither diagnose nor exclude maternal-infant transmission. The diagnosis of infection period depends on the dynamic changes in viral load from birth through the follow-up period but whether the infection occurred in utero, at delivery or during the neonatal period could not be determined.

RESUMO

UNLABELLED: Hepatitis B virus (HBV) infection is of high prevalence in China. Mother-to-infant transmission is the major route for HBV transmission and subsequent chronicity. This study aimed to investigate current HBsAg-positive rate among pregnant women and immunoprophylaxis outcome in China. Multicenter prospective study was conducted in 10 centers. From 2008 to 2012, 67,720 pregnant women were screened and 1,150 HBsAg-carrier mothers and their infants aged 8-12 months were studied in four out of all centers, among whom HBV markers (HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb) and HBV DNA (in three centers) were measured. The results showed that HBsAg-positive rate of pregnant women was 6.7 % (4,533/67,720) and infants' immunoprophylaxis failure rate was 3.4 % (39/1,150). Immunoprophylaxis failure infants were all born to mothers of HBeAg-positive and HBV DNA ≥6 log10 copies/ml. Among infants of HBeAg-positive mothers, multivariable analyses showed the following: mother's age <28 years vs ≥28 years, RR = 0.157, 95 % confidence interval (CI) [0.067, 0.369], p = 0.000; Neonates receiving vaccine vs vaccine plus hepatitis B immune globulin (HBIG), RR = 0.371, 95 % CI [0.167, 0.825], p = 0.015. Pregnant women receiving HBIG in the third trimester, vaginal delivery and breastfeeding had no significant effects on HBV mother-to-infant transmission. CONCLUSIONS: Pregnant women are still of high HBsAg prevalence in China. HBV mother-to-infant transmission still occurs after passive-active immunization. Pregnant women of high HBV replication levels are the major risk population of HBV mother-to-infant transmission. Passive-active immunization is necessary for neonates of HBeAg-positive mothers. Mother's age <28 years and neonate receiving vaccine only were the risk factors for HBV mother-to-infant transmission. Breastfeeding did not put children at risk of mother-to-infant transmission.

RESUMO

INTRODUCTION: The window period, defined as HIV nucleic acid test (NAT) reactivity but Western blot (WB) test inconclusive, is garnering more attention. Improving the detection efficiency of HIV high-risk populations in the window period is critical to reducing the risk of unanticipated transmission. The purpose of this study was to create an additional strategy for distinguishing indeterminate HIV infection cases. METHODS: Based on WB follow-up results, the individuals in this study were divided into persons in the HIV window period and persons without HIV. Plasma was analyzed using quantitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) to detect differentially expressed proteins (DEPs). The biological implications of these DEPs were investigated using enrichment analysis. Protein-protein interaction (PPI) analysis and LASSO regression were used to identify key proteins. The calibration curve, decision curve, and nomogram were utilized to create the model. RESULTS: Fifty-seven DEPs were screened out, with 33 up-regulated and 24 down-regulated in persons with HIV at window period. The most important Gene Ontology (GO) enrichment items are oxidoreductase activity and heme binding. Oxidoreductases account for half of the 10 main proteins identified from various DEPs. An auxiliary diagnostic model comprised of peroxiredoxin-2 (P32119), band 3 anion transport protein (P02730), and histone H2A type 1 (P0C0S8) was developed. The results of the confusion matrix parameters revealed that this diagnostic approach had strong practicability in distinguishing indeterminate HIV infection cases. CONCLUSIONS: The three DEPs identified and predicted by proteomics are useful for the supplemental identification of persons in the HIV window period.

RESUMO

BACKGROUND: The burden of hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis coinfections remains disproportionately high among people living with HIV/AIDS. Hubei province is located in central China, where there are distinct regional characteristics of the distribution of people living with HIV/AIDS acquired via diverse transmission routes and the AIDS epidemic itself. OBJECTIVE: We aimed to estimate the magnitude of HBV, HCV, or syphilis coinfections among people living with HIV/AIDS with blood-borne transmission, which includes former paid blood donors, contaminated blood recipients, and intravenous drug users, as well as among people with sex-borne HIV transmission (including heterosexual people and men who have sex with men) and people with mother-to-child HIV transmission. METHODS: From January 2010 to December 2020, people living with HIV/AIDS were tested for hepatitis B surface antigen (HBsAg), HCV antibodies, and syphilis-specific antibodies. The positive patients were further tested for HBV markers, HBV DNA, and HCV RNA, and received a rapid plasma reagin circle card test. All people living with HIV/AIDS were first divided into transmission groups (blood, sex, and mother-to-child); then, people with blood-borne HIV transmission were divided into former paid blood donors, contaminated blood recipients, and intravenous drug users, while people with sex-borne HIV transmission were divided into heterosexual people and men who have sex with men. RESULTS: Among 6623 people living with HIV/AIDS, rates of chronic HCV infection were 80.3% (590/735) in former paid blood donors, 73.3% (247/337) in intravenous drug users, 57.1% (444/777) in contaminated blood recipients, 19.4% (21/108) in people with mother-to-child HIV transmission, 8.1% (240/2975) in heterosexual people, and 1.2% (21/1691) in men who have sex with men. Chronic HBV infection rates were similar among all people with blood-borne HIV transmission. However, compared to heterosexual people, the chronic HBV infection rate was greater in men who have sex with men (213/1691, 12.6% vs 308/2975, 10.4%; χ21=5.469; P=.02), although HBV exposure was less common (827/1691, 48.9% vs 1662/2975, 55.9%; χ21=20.982; P<.001). Interestingly, the combination of HBsAg and hepatitis B e antigen (HBeAg) was found in 11 patients with sex-borne HIV transmission, but in 0 people with blood-borne HIV transmission (11/196, 5.6% vs 0/521, 0%; χ21=29.695, P<.001). In people with sex-borne HIV transmission, the proportions of patients with a syphilis titer ≥1:16 and neurosyphilis were 8.6% (105/1227) and 7.8% (37/473), respectively, whereas these values were 0 in people with blood-borne HIV transmission. CONCLUSIONS: In people living with HIV/AIDS, HCV transmission intensity was significantly associated with specific exposure modes of blood or sexual contact. The rate of chronic HBV infection among men who have sex with men was higher than in any other population. Attention should be paid to the high prevalence of neurosyphilis in people living with HIV/AIDS who contract HIV by sexual intercourse.

RESUMO

BACKGROUND: Due to economic shortages and concern about occupational exposure to HIV, liver biopsy and transient elastography (TE) are rarely available in patients with HIV/HBV co-infection in China, where HIV/HBV co-infection is prevalent. METHODS: The accuracy of FIB-4 and APRI for predicting liver fibrosis was compared with TE results in a series of 460 HIV/HBV co-infected patients. RESULTS: FIB-4 and APRI scores were strongly correlated to liver stiffness measurement scores by TE, and the correlation index was 81.4-96.3. An FIB-4 index >1.5 had a positive predictive value of 95.2% to consider fibrosis with a sensitivity of 85.7%. An APRI index >0.5 had a positive predictive value of 98.2% to consider fibrosis with a sensitivity of 76.0%. A FIB-4 value <1.5 or APRI <0.5 were concordant with TE results to exclude fibrosis in 94.4% and 96.8%, respectively. A FIB-4 value >1.5 or APRI >0.5 were concordant with fibrosis diagnosed by TE in 77.6-89.4% and 70.7-80.9%, respectively. CONCLUSIONS: In areas with limited resources, FIB-4 and APRI indexes were accurate, simple and inexpensive methods for assessing liver fibrosis in patients with HIV/HBV co-infection.

RESUMO

Background: To analyze the changing characteristics of continuous monitoring of refined lymphocyte subsets in people living with HIV/AIDS (PLWHA) during ART period. Methods: Refined lymphocyte subsets was continuously monitored using flow cytometry for 173 PLWHA, who were hospitalized in Zhongnan Hospital of Wuhan University from August 17, 2021 to September 14, 2022. The effect of ART status and duration of ART on changes of refined lymphocyte subsets were compared in different groups. Then, the levels of refined lymphocyte subsets in PLWHA treated for more than 10 years were compared to those of 1086 healthy individuals. Results: In addition to conventional CD4+ T lymphocytes and CD4+/CD8+ ratio, gradually increasing in numbers of CD3+CD4+CD45RO cells, CD3+CD4+CD45RA cells, CD45RA+CD3+CD4+CD25+CD127low and CD45RO+CD3+CD4+CD25+CD127low cells were found with the increase of ART duration. The number of CD4+CD28+ cells and CD8+CD28+ cells were 174/ul and 233/ul at 6 months post-ART, which gradually increased to 616/ul and 461/ul after ART initiation more than 10 years. Moreover, in ART ≤ 6 months, 6 months-3years, 3-10 years and >10 years groups, the percentage of CD3+CD8+HLA-DR+/CD8 were 79.66%, 69.73%, 60.19% and 57.90%, respectively, and the differences between groups showed statistical significance (F=5.727, P=0.001). For those PLWHA with ART more than 10 years, the levels of CD4+ T lymphocytes, CD3+CD4+CD45RO cells, CD3+CD4+CD45RA cells, CD4+CD28+ cells and CD8+CD28+ cells can increase to levels similar to those of healthy control. However, for those PLWHA with ART more than 10 years, CD4+/CD8+ ratio was 0.86 ± 0.47, which was lower than that of healthy control (0.86 ± 0.47 vs 1.32 ± 0.59, t=3.611, P=0.003); absolute counts and percentage of CD3+CD8+HLA-DR+ cells were 547/ul and 57.90%, which were higher than those of healthy control(547/ul vs 135/ul, t=3.612, P=0.003; 57.90% vs 22.38%, t=6.959, P<0.001). Conclusion: Persistent ART can gradually improve the immune status of PLWHA, which is manifested in the increase of lymphocytes, function recovery of lymphocytes and reduction of aberrant activation status of the immune system. After 10 years of standardized ART, most lymphocytes could return to levels of healthy persons, although it may take longer to complete recovery for CD4+/CD8+ ratio and CD3+CD8+HLA-DR+ cells.

RESUMO

OBJECTIVE: To investigate prevalence HPV infections in cervix among HIV-infected Chinese women. METHODS: From September 2009 to May 2011, 293 women with positive HIV underwent cervical cancer screening as study group matched with 200 women with negative HIV as control group. Questionnaires including demographic information and HIV associated information were collected, Pap smear and 23 subtype of HPV were performed in those women. The women with positive HPV were followed up per 6 months, and the period of following up were more than 12 months. Binary logistic analysis was used for high risk factors of HPV persistent infection. RESULTS: Prevalent HPV infection was 44.4% (130/293) in study group and 20.0% (40/200) in control group, respectively, which reached statistical difference (P < 0.05). The most common genotype of HPV was HPV 16, which prevalence was 13.7% (40/293) in study group and 7.0% (14/200) in control group. The other HPV subtype prevalence was HPV-58, HPV-52, HPV-43 and HPV-18, which was 9.2% (27/293), 8.2% (24/293), 8.2% (24/293), 6.8% (20/293) in study group and 3.0% (6/200), 2.5% (5/200), 1.5% (3/200), 2.5% (5/200) in control group. At time point of 12 months following up, the persistent prevalence of HPV was 47.5% (48/101) in study group and 21.1% (8/38) in control group, which reached statistical difference (P < 0.05). Multiple HPV infections (OR = 6.4, 95%CI: 1.6 - 25.6), abnormal cytology (OR = 18.1, 95%CI: 4.5 - 76.9) and lower CD(4) T cell count (compared with CD(4) > 3.5 × 10(8)/L, if 2.0 × 10(8) ≤ CD(4) ≤ 3.5 × 10(8), OR = 8.1, 95%CI: 1.3 - 56.3; if CD(4) < 2.0 × 10(8)/L, OR = 9.1, 95%CI: 1.8 - 46.9) were independently associated with HPV persistence among HIV-positive subjects. CONCLUSIONS: Prevalence and persistence of HPV infections were more common among HIV-positive Chinese women than those in HIV-negative Chinese women. Improving immune function, decreasing multiple HPV infections, treating abnormal cervical cytology could decrease prevalence of HPV infection.

RESUMO

Clinical management and optimal treatment are essential to improving outcomes for people living with HIV (PLWH). We assessed trends and outcomes of chronic kidney disease (CKD) in PLWH in a resource-limited center of central China. All PLWH who were followed up in a tertiary referral center in Wuhan, China, from July 2016 to June 2021 were evaluated. CKD was defined as glomerular filtration rate (GFR) <60 mL/min/1.73 m2 during two consecutive measurements 3 months apart. Baseline characteristics of the participants were extracted from the hospital medical records. The prevalence rate and associated risk factors of CKD were analyzed. A total of 863 PLWH with normal kidney function at baseline were analyzed. The median age was 33 (interquartile ranges: 26-49) years, and 778 (90.2%) were male and 85 (9.8%) were female. Among them, 50 (5.8%) had their GFR falling below 60 mL/min/1.73 m2 after a median of 54 months. Adjusted multivariate logistic regression revealed older age [adjusted odds ratio (aOR) = 1.04, 95% confidence interval (95% CI): 1.01-1.07], female sex (aOR = 3.17, 95% CI: 1.14-8.84), lower body weight (aOR = 0.95, 95% CI: 0.91-1.00), lower hemoglobin (aOR = 3.54, 95% CI: 1.51-8.30), longer duration of antiretroviral therapy exposure (aOR = 1.02, 95% CI: 1.00-1.04), and a baseline GFR between 60 and 90 mL/min/1.73 m2 (aOR = 3.89, 95% CI: 1.21-12.46) were associated with the development of CKD. Our findings showed that CKD is not infrequent in PLWH with a combination of traditional and HIV-specific risk factors for kidney disease, highlighting the suboptimal monitoring and treatment options of CKD in PLWH in resource-limited settings. Scalable monitoring strategy to improve care for this population is warranted.

RESUMO

The clinical and cellular interactions between hepatitis B virus (HBV) and hepatitis C virus (HCV) were investigated in patients co-infected with the human immunodeficiency virus (HIV). One hundred ninety-nine patients followed for 6 years were evaluated to compare the level of HBV DNA and HCV RNA in patients co-infected with HIV and HBV, and patients co-infected with HIV, HBV, and HCV. A full-length HBV genome and HCV JFH1 RNA were co-transfected into HuH-7.5.1 cells in vitro to examine the impact of co-infection and dependence on the HBV PreC mutant for replication interference. Before 2',3'-dideoxy-3'-thiacytidine (3TC)-based antiretroviral therapy (ART) was initiated, HBV DNA was found in 56/123 (45.4%) patients co-infected with HIV and HBV, and in 19/76 (25.0%) patients co-infected with HIV, HBV, and HCV. After 3TC-based ART was initiated, detectable HBV DNA decreased to 7/76 (9.2%) in patients co-infected with HIV, HBV, and HCV, but HCV RNA increased from 43/76 (56.6%) to 60/76 (78.9%) (P = 0.003). In vitro HBV and HCV co-infection led to decreased replication of both viruses. The primary factors that influenced the decreased replication were the order of the HBV and HCV infection and the HBV PreC mutation.

RESUMO

OBJECTIVES: To analyze characteristics of asymptomatic/pres-ymptomatic patients with SARS-CoV-2 infection. METHODS: Chest computed tomography(CT), indicators for organ and coagulation function, inflammation cytokines, of asymptomatic/pre-symptomatic patients with SARS-CoV-2 infection were retrospectively analyzed in Zhongnan Hospital of Wuhan University from 20 December 2019, to 8 March 2020. RESULTS: The proportion of normal chest CT in asymptomatic and pre-symptomatic patients with SARS-CoV-2 infection were 35.4% (17/48) and 3.3%(2/61), respectively (P< 0.001). In 17 asymptomatic patients, their images of chest CT maintained normal during the whole course of diseases, while the normal images of chest CT in 2 pre-symptomatic patients progressed to abnormal later (P< 0.001). All the six asymptomatic patients with SARS-CoV-2 infection maintained unilateral lesion, while the proportion was 29.4%(5/17) in pre-symptomatic patients(P= 0.003). Compared with asymptomatic patients, pre-symptomatic COVID-19 patients had worse levels of Lymphocyte count (P= 0.001), Albumin (P= 0.045), Aspartate aminotransferase (P= 0.044), γ-glutamyl transpeptadase (P= 0.016), Globulin (P= 0.036), Creatinine (P= 0.021), Lactate dehydrogenase (P= 0.008), C-reactive protein (P< 0.001), Serum amyloid A (P< 0.001), and Erythrocyte sedimentation rate (P< 0.001). Except for above indicators, Alkaline phosphatase (P= 0.009), Procalcitonin (P= 0.010), and D-dimer(P< 0.001) increased further during periods of symptoms compared with those levels in pre-symptomatic period. CONCLUSION: In early stage after SARS-CoV-2 infection, images of chest CT and blood tests of asymptomatic patients were different from pre-symptomatic patients.

RESUMO

BACKGROUND: Information about the impact of HIV coinfection on clinical characteristics of COVID-19 patients remains limited. 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.

RESUMO

BACKGROUND: Liver injury in coronavirus disease 2019 (COVID-19) patients was poorly understood. METHODS: The markers of liver injury, severity of disease and prognosis among 495 COVID-19 patients in Zhongnan Hospital of Wuhan University from 1st January 2019 to 11th March 2019 were retrospectively analyzed. RESULTS: The levels of aspartate aminotransferase (AST) (50.1 ± 38.4 vs. 31.4 ± 39.1, P < 0.001), gamma-glutamyl transpeptidase (GGT) (70.3 ± 70.2 vs. 34.1 ± 34.7, P < 0.001) and fibrinogen-to-albumin-ratio (FAR) (13.4 ± 4.0 vs. 10.4 ± 3.4, P < 0.001) were greater than mild COVID-19 patients, whereas the levels of albumin(35.0 ± 6.2 vs. 39.9 ± 3.7, P < 0.001) and albumin/globulin (A/G) ratio (1.21 ± 0.24 vs. 1.50 ± 0.31, P < 0.001) were lower in severe COVID-19 patients. By comparing the changes of liver injury markers 7-10 days after hospitalization, the level of albumin deteriorated from 35.0 ± 6.2 to 30.20 ± 5.5 (P < 0.001), A/G ratio from 1.21 ± 0.24 to 1.06 ± 0.25 (P < 0.001), and FAR from 13.4 ± 4.0 to 15.4 ± 2.9(P < 0.001) in severe COVID-19 patients, while the changes of albumin, A/G ratio and FAR showed opposite patterns in mild COVID-19 patients. FAR > 12 [2.566 (1.410-4.670), P = 0.012) on admission and changes of albumin >5g/l [22.489 (6.422-78.757), P = 0.001] were two risk factors for death, and the sensitivity and specificity for the poor prognosis were 80.8% and 64.0%, 82.6% and 76.3%, respectively. CONCLUSION: The levels of AST, GGT, albumin and FAR are correlated with disease severity after severe acute respiratory syndrome coronavirus-2 infection. FAR > 12 on admission and changes of albumin > 5 g/l were good predictors for the prognosis of COVID-19 patients.
