ObjectivesTo evaluate whether nephrotic syndrome (NS) and further corticosteroid (CS) use increase the risk of osteoporosis in Asian population during the period January 2000–December 2010. DesignNationwide population-based retrospective cohort study. SettingAll healthcare facilities in Taiwan. ParticipantsA total of 28 772 individuals were enrolled. Interventions26 614 individuals with newly diagnosed NS between 2000 and 2010 were identified and included in out study. 26 614 individuals with no NS diagnosis prior to the index date were age matched as controls. Diagnosis of osteoporosis prior to the diagnosis of NS or the same index date was identified, age, sex and NS-associated comorbidities were adjusted. Primary outcome measureTo identify risk differences in developing osteoporosis among patients with a medical history of NS. ResultsAfter adjusting for covariates, osteoporosis risk was found to be 3.279 times greater in the NS cohort than in the non-NS cohort, when measured over 11 years after NS diagnosis. Stratification revealed that age older than 18 years, congestive heart failure, hyperlipidaemia, chronic kidney disease, liver cirrhosis and NS-related disease including diabetes mellitus, hepatitis B infection, hepatitis C infection, lymphoma and hypothyroidism, increased the risk of osteoporosis in the NS cohort, compared with the non-NS cohort. Additionally, osteoporosis risk was significantly higher in NS patients with CS use (adjusted HR (aHR)=3.397). The risk of osteoporosis in NS patients was positively associated with risk of hip and vertebral fracture (aHR=2.130 and 2.268, respectively). A significant association exists between NS and subsequent risk for osteoporosis. ConclusionNS patients, particularly those treated with CS, should be evaluated for subsequent risk of osteoporosis.

Abstract Background Existing research in Ethiopia has primarily focused on the individual epidemiology of HIV and HBV, often overlooking the intricate dynamics of co-infection. This study aims to address this gap by comprehensively exploring the prevalence of HBV and HIV co-infection and the associated factors influencing co-infection rates within the specific context of ART clinics. The existing study provides limited insights into the unique challenges posed by this dual infection in the Ethiopian population receiving ART. Methods An institutional-based cross-sectional study was conducted among people living with HIV aged 18 years and above attending ART clinics in northeast Ethiopia from April to May 2022. A sample size of 350(97% response rate) participants was selected by using a systematic random sampling method. Data were collected using a pre-tested interviewer-administered structured questionnaire. Data was entered into Epi Data version software and was exported to SPSS version 25 for further analysis. Descriptive statistics using Frequency, proportion, and summary measures were done. Binary logistic regressions were done to identify independent variables associated with HBV infection among HIV patients. A P-value less than 0.05 and adjusted odds ratio with a 95% confidence interval non-inclusive of one was considered statistically significant. Results The prevalence of Hepatitis B Surface Antigen (HBsAg) was identified constituting 7.14% of the study population. Females [AOR] 0.14; 95% Confidence Interval [CI] [0.041–0.478]). Participants with an educational status of only reading and writing (AOR 8.7; 95% CI [1.143–66.5]). Single individuals (AOR 2.04; 95% CI [1.346–28.6]) were associated factors. Moreover, participants with a viral load exceeding 1000 copies/ml were 6.5 times more likely to be infected with HBV compared to those with undetectable viral loads (AOR 6.53, 95% CI [1.87–22.72]). Additionally, individuals with a CD4 count ranging from 351 to 500 cells/ml were 1.2 times more likely to be infected with HBV compared to those with a CD4 count of 500 cells/ml or above (AOR 10.4, 95% CI [1.28-85]). Conclusion The prevalence of HBV infection was found to be intermediate in HIV-infected patients in the study area. Being male, marital status of single and divorced, educational level was only read and written, current viral load of > 1000 copies/ml &

Abstract Background Hepatitis C virus (HCV) infection poses a major public health challenge globally, especially among injecting drug users. China has the world’s largest burden of HCV infections. However, little is known about the characteristics of transmission networks among drug user populations. This study aims to investigate the molecular epidemiology and transmission characteristics of HCV infections among drug users in Zhuhai, a bustling port city connecting Mainland China and its Special Administrative Regions. Methods Participants enrolled in this study were drug users incarcerated at Zhuhai’s drug rehabilitation center in 2015. Their sociodemographic and behavioral information, including gender, promiscuity, drug use method, and so forth, was collected using a standardized questionnaire. Plasmas separated from venous blood were analyzed for HCV infection through ELISA and RT-PCR methods to detect anti-HCV antibodies and HCV RNA. The 5’UTR fragment of the HCV genome was amplified and further sequenced for subtype identifications and phylogenetic analysis. The phylogenetic tree was inferred using the Maximum Likelihood method based on the Tamura-Nei model, and the transmission cluster network was constructed using Cytoscape3.8.0 software with a threshold of 0.015. Binary logistic regression models were employed to assess the factors associated with HCV infection. Results The overall prevalence of HCV infection among drug users was 44.37%, with approximately 19.69% appearing to clear the HCV virus successfully. Binary logistic regression analysis revealed that those aged over 40, engaging in injecting drug use, and being native residents were at heightened risk for HCV infection among drug user cohorts. The predominant HCV subtypes circulating among those drug users were 6a (60.26%), followed by 3b (16.7%), 3a (12.8%), 1b (6.41%) and 1a (3.85%), respectively. Molecular transmission network analysis unveiled the presence of six transmission clusters, with the largest propagation cluster consisting of 41 individuals infected with HCV subtype 6a. Furthermore, distinct transmission clusters involved eight individuals infected with subtype 3b and seven with subtype 3a were also observed. Conclusion The genetic transmission networks revealed a complex transmission pattern among drug users in Zhuhai, emphasizing the imperative for a targeted and effective intervention strategy to mitigate HCV dissemination. These insights are pivotal for shaping future national policies on HCV screening, treatment, and prevention in port cities.

Background: In the Phase 3 ALLIANCE study, both bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) and dolutegravir plus emtricitabine/tenofovir disoproxil fumarate (DTG + F/TDF) achieved high rates of HIV-1 RNA suppression through Week 96 in adults with HIV-1 and hepatitis B virus (HBV) initiating treatment (NCT03547908). Here, we quantify preexisting HIV-1 resistance, evaluate its effect on HIV-1 virologic suppression, and describe postbaseline HIV-1 resistance through Week 96. Methods: Preexisting HIV-1 resistance was assessed by historical and/or screening genotyping. HIV-1 RNA suppression to

by Sarah Kimball, Marley Reynoso, Courtney McKnight, Don Des Jarlais Background The prevalence of hepatitis C virus (HCV) among people who inject drugs (PWID) is between 50–70%. Prior systematic reviews demonstrated that PWID have similar direct acting antiviral treatment outcomes compared to non-PWID; however, reviews have not examined treatment outcomes by housing status. Given the links between housing and health, identifying gaps in HCV treatment can guide future interventions. Methods We conducted a systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched six databases for articles from 2014 onward. Two reviewers conducted title/abstract screenings, full-text review, and data extraction. We extracted effect measures for treatment initiation, adherence, completion, success, and reinfection by housing status. Studies underwent quality and certainty assessments, and we performed meta-analyses as appropriate. Results Our search yielded 473 studies, eight of which met inclusion criteria. Only the treatment initiation outcome had sufficient measures for meta-analysis. Using a random-effects model, we found those with unstable housing had 0.40 (0.26, 0.62) times the odds of initiating treatment compared to those with stable housing. Other outcomes were not amenable for meta-analysis due to a limited number of studies or differing outcome definitions. Conclusions Among PWID, unstable housing appears to be a barrier to HCV treatment initiation; however, the existing data is limited for treatment initiation and the other outcomes we examined. There is a need for more informative studies to better understand HCV treatment among those with unstable housing. Specifically, future studies should better define housing status beyond a binary, static measure to capture the nuances and complexity of housing and its subsequent impact on HCV treatment. Additionally, researchers should meaningfully consider whether the outcome(s) of interest are being accurately measured for individuals experiencing unstable housing.

Abstract Background Hepatitis C virus (HCV) and hepatitis B virus (HBV) cause chronic hepatitis with important clinical differences. HCV causes hepatic steatosis and insulin resistance, while HBV confers increased risk of liver cancer. We hypothesised these differences may be due to virus-specific effects on mitochondrial function.Methods Seahorse technology was utilised to investigate effects of virus infection on mitochondrial function. Cell based assays were used to measure mitochondrial membrane potential and quantify pyruvate and lactate. Mass spectrometry was performed on mitochondria isolated from HBV expressing, HCV infected and control cells cultured with isotope-labelled amino acids, to identify proteins with different abundance. Altered expression of key mitochondrial proteins was confirmed by real time PCR and western blot.Results Reduced mitochondrial function and ATP production were observed with HCV infection and HBV expression. HCV impairs glycolysis and reduces expression of genes regulating fatty acid oxidation, promoting lipid accumulation. HBV causes lactate accumulation by increasing expression of lactate dehydrogenase A, which converts pyruvate to lactate. In HBV expressing cells there was marked enrichment of pyruvate dehydrogenase kinase, inhibiting conversion of pyruvate to acetyl-CoA and thereby reducing its availability for mitochondrial oxidative phosphorylation.Conclusions HCV and HBV impair mitochondrial function and reduce ATP production. HCV reduces acetyl-CoA availability for energy production by impairing fatty acid oxidation, causing lipid accumulation and hepatic steatosis. HBV has no effect on fatty oxidation but reduces acetyl-CoA availability by disrupting pyruvate metabolism. This promotes lactic acidosis and oxidative stress, increasing the risk of disease progression and liver cancer.
