Seroprevalence of HIV with Hepatitis B and C Co-Infection in Patients at the Al Nadjma Multi-purpose Center Laboratory in N'Djamena, Chad

Co-infection with hepatitis B and C is one of the major challenges in the management of HIV since access to antiretroviral drugs has improved in Africa. The aim of this study was to determine the seroprevalence HIV/Hep B and C co-infection in patients treated at the Al Nadjma multi-purpose centre in N'Djamena, Chad. This prospective study was conducted from June 2023 to May 2024 on 3,430 patients seen at the laboratory of the Al Nadjma multi-purpose Center in N'Djamena for screening for both HIV and hepatitis B and C. HIV was detected by immuno-chromatography using specific kits. The detection of hepatitis B and C by detection of HBsAg and HCV AC was carried out by immunochromatography using specific kits. The mean age of the patients was 38 years, with extremes of 18 and 60 years. Males were predominant (71.2%), with a sex ratio (M/F) of 1.22. The most common age was 31 to 40 (38.48%). The prevalence of HIV, hepatitis B and hepatitis C was 4.84%, 4.46% and 0.93% respectively. The prevalence of HIV/HBV, HIV/HCV and HIV/HBV/HCV co-infections was 4.17%, 0.79% and 0.09% respectively. This study shows that HIV and hepatitis B seroprevalence are high in N'Djamena. On the other hand, hepatitis C virus and HIV/HCV and HIV/HBV/HCV co-infections are relatively low compared with most of the data reported in other Sub-Saharan African countries. However, HIV/HBV co-infection could be considered a public health problem, requiring early diagnosis by organizing awareness and screening campaigns in the population, thus enabling better management of co-infected patients (HIV/HBV) by dual antiretroviral and anti-hepatitis B treatment.

Evaluating the Efficacy of Repurposed Antiretrovirals in Hepatitis B Virus Treatment: A Narrative Review of the Pros and Cons

Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) continue to be global public health issues. Globally, about 39.9 million persons live with HIV in 2023, according to the Joint United Nations Programme on HIV/AIDS (UNAIDS) 2024 Fact Sheet. Consequently, the World Health Organisation (WHO) reported that about 1.5 million new cases of HBV occur, with approximately 820 thousand mortalities yearly. Conversely, the lower percentage of HBV (30%) cases that receive a diagnosis is a setback in achieving the WHO 2030 target for zero HBV globally. This has necessitated a public health concern to repurpose antiretroviral (ARV) drugs for the treatment of HBV diseases. This review provides an introductory background, including the pros and cons of repurposing antiretrovirals (ARVs) for HBV treatment. We examine the similarities in replication mechanisms between HIV and HBV. We further investigate some clinical studies and trials of co-infected and mono-infected patients with HIV–HBV. The topical keywords including repurposing ARV drugs, repurposing antiretroviral therapy, Hepatitis B drugs, HBV therapy, title, and abstracts are searched in PubMed, Web of Science, and Google Scholar. The advanced search includes the search period 2014–2024, full text, clinical trials, randomized control trials, and review. The search results filtered from 361 to 51 relevant articles. The investigations revealed that HIV and HBV replicate via a common route known as ‘reverse transcription’. Clinical trial results indicate that an early initiation of ARVs, particularly with tenofovir disoproxil fumarate (TDF) as part of a regimen, significantly reduced the HBV viral load in co-infected patients. In mono-infected HBV, timely and correct precise medication is essential for HBV viral load reduction. Therefore, genetic profiling is pivotal for successful ARV drug repurposing in HBV treatment. Pharmacogenetics enables the prediction of the right dosages, specific individual responses, and reactions. This study uniquely explores the intersection of pharmacogenetics and drug repurposing for optimized HBV therapy. Additional in vivo, clinical trials, and in silico research are important for validation of the potency, optimum dosage, and safety of repurposed antiretrovirals in HBV therapy. Furthermore, a prioritization of research collaborations comprising of regulators and funders to foster clinically adopting and incorporating repurposed ARVs for HBV therapy is recommended.

Metagenomics: a new frontier for routine pathology testing of gastrointestinal pathogens

BackgroundAccurate and comprehensive identification of enteropathogens, causing infectious gastroenteritis, is essential for optimal patient treatment and effective isolation processes in health care systems. Traditional diagnostic techniques are well established and optimised in low-cost formats. However, thorough testing for a wider range of causal agents is time consuming and remains limited to a subset of pathogenic organisms. Metagenomic next-generation sequencing (mNGS) allows the identification of all pathogens in a sample in a single test, without a reliance on culture or introduction of target selection bias. This study aims to determine the ability to routinely apply mNGS testing, in comparison to traditional culture or polymerase chain reaction (PCR) based tests, for the identification of causal pathogens for gastrointestinal infections.ResultsThe performance of mNGS, PCR and microscopy, culture and sensitivity (MCS) assays was established using 2,619 prospectively collected faecal samples from patients with symptomology indicative of infectious gastroenteritiss. Commonly experienced pathogens including Aeromonas spp, Campylobacter spp, Salmonella spp and Giardia spp, in single and co-infected patients, were used to establish test outcomes. When testing for these organisms, using the combined result from either or both PCR and MCS testing as the comparator, the mNGS assay had clinically acceptable sensitivity (89.2–100%). Further, the mNGS assay detected 14 additional enteropathogens, that were either not detected or not tested, by initial PCR/MCS testing.ConclusionsThe advantage of mNGS compared to other syndromic testing systems is the broad range of detectable targets and the ability to interrogate samples without clinician informed or assay specific bias. With the development of newer sequencing assays, it is now feasible to test for a wide range of target organisms in a sample using a single mNGS test. Overall, the mNGS based approach enabled pathogen detection that was comparable to conventional diagnostics and was shown to have the potential to be extended for the detection of many pathogens and genes of clinical interest. In conclusion, the mNGS assay offers an easy, sample to answer workflow with rapid detection of enteropathogens and has the potential to improve diagnosis, therapy and infection control precautions.

Additive Effects of Glutathione in Improving Antibiotic Efficacy in HIV-M.tb Co-Infection in the Central Nervous System: A Systematic Review.

HIV and tuberculosis (TB) co-infection poses a significant health challenge, particularly when involving the central nervous system (CNS), where it leads to severe morbidity and mortality. Current treatments face challenges such as drug resistance, immune reconstitution inflammatory syndrome (IRIS), and persistent inflammation. Glutathione (GSH) has the therapeutic potential to enhance treatment outcomes by improving antibiotic efficacy, reducing inflammation, and mitigating immune dysfunction. Relevant studies were identified through systematic searches of PubMed, Elsevier, WHO, and related databases. Inclusion criteria focused on preclinical and clinical research examining GSH or its precursors in HIV, TB, or co-infection, with emphasis on microbial control, immune modulation, and CNS-related outcomes. Preclinical studies showed that GSH improves macrophage antimicrobial function, reduces oxidative stress, and limits Mycobacterium tuberculosis (M.tb) growth. Animal models demonstrated reduced bacterial burden in the lungs, liver, and spleen with GSH supplementation, along with enhanced granuloma stability. Clinical studies highlighted increased TH1 cytokine production, reduced inflammatory markers, and improved CD4+ T cell counts in HIV-M.tb co-infected patients. N-acetylcysteine (NAC), a GSH precursor, was shown to significantly enhance the efficacy of first-line TB antibiotics and mitigate treatment-associated toxicity. GSH shows promise as an adjunct therapy for HIV-M.tb co-infection, particularly for cases involving the CNS, where it may improve immune recovery and reduce inflammation. However, evidence is limited by small sample sizes and a lack of randomized trials. Future research should focus on developing CNS-directed GSH formulations and evaluating its integration into current treatment protocols to address the dual burden of HIV and TB, ultimately improving patient outcomes.

Profound Immunosuppression with Reversed CD4:CD8 Ratio in a Tuberculosis Patient with Acquired Immunodeficiency Syndrome: A Case Report

Background: The co-occurrence of tuberculosis (TB) and acquired immunodeficiency syndrome (AIDS) presents a formidable clinical challenge due to the synergistic impact on the immune system. This case report describes a patient with TB/AIDS co-infection exhibiting profound immunosuppression characterized by a severely diminished CD4 count and an unusual reversal of the CD4:CD8 ratio. Case presentation: A 39-year-old male presented with symptoms indicative of both TB and advanced HIV infection, including shortness of breath, weight loss, and oral thrush. Physical examination revealed bilateral lung crackles. Laboratory investigations confirmed pulmonary TB and revealed a critically low CD4 count (6 cells/µL), and a CD8 count of 71 cells/µL, resulting in a reversed CD4:CD8 ratio of 0.08. The patient's HIV viral load was markedly elevated at 598,403 copies/mL. This case underscores the complex interplay between TB and HIV, highlighting the profound impact of co-infection on immune system function. The patient's severely depleted CD4 count and the atypical CD4:CD8 ratio reflect the advanced stage of HIV infection and the superimposed TB. The findings emphasize the need for close monitoring and aggressive management of co-infected patients to mitigate the risk of opportunistic infections and disease progression. Conclusion: This case report documents a rare and severe presentation of TB/AIDS co-infection with profound immunosuppression and a reversed CD4:CD8 ratio. It serves as a reminder of the significant morbidity and mortality associated with advanced HIV and TB co-infection, particularly in cases of delayed diagnosis or suboptimal treatment adherence.

Effects of Hbv and Hcv on Cd4+ T-Lymphocytes Count and Two Liver Enzymes of Hiv-Infected Patients in Orlu, Imo State, Nigeria

Co-infection of Hepatitis B virus (HBV) and Hepatitis C virus (HCV) are very prevalent and the primary cause for morbidity and mortality among patients with Human immunodeficiency virus (HIV). The aim of the study was to assess the effect of HBV and HCV on CD4+ count and two liver enzymes; Aspartate transaminase (AST) and Alanine transaminase (ALT), among HIV-infected patients. The study was a hospital based cross-sectional study conducted at the anti-retroviral therapy (ART) clinics in Orlu, Imo State, Nigeria. Whole blood samples were collected from 720 patients and serologically analyzed for HBsAg and Anti-HCV using test strips. The samples were also analyzed for the CD4+ count using Cyflow conting system, and two liver enzymes (AST and ALT) using an auto-chemistry analyzer (Cobas C111). Data were entered and analyzed by SPSS version 29 and p-value less than 0.05 was taken as significant. Of the 720 patients, 514 (71.4%) were females and 206 (28.6%) were males. The overall prevalence of HIV/HBV, HIV/HCV, HIV/HBV/HCV, and HIV alone were 332 (46.1%), 82 (11.4%), 105 (14.6%), and 201 (27.9%), respectively. Generally, HIV patients co-infected with HBV and/or HCV had lower mean CD4+ count, AST, and ALT compared to those with HIV alone, but only that of those co-infected with both HBV and HCV were statistically significant (p < 0.05). The HIV/HBV/HCV patients have CD4+ count, AST, and ALT of 76.25 cell/µL, 13.47 IU/L, and 12.20 IU/L, respectively compared to 506.60 cell/ µL, 199.81 IU/L, and 65.85 IU/L observed among those having only HIV, respectively. In a unisex comparison, the male patients with HIV/HBV had significantly lower AST and ALT than male patients with HIV only (p < 0.05). But, male and female patients with HIV/HBV/HCV had significantly lower AST and ALT compared to the males and females with HIV only (p < 0.05), respectively. Across gender, only HIV/HBV/HCV patients had significantly lower CD4+ and AST in males compared to females (p < 0.05). There was no statistically significant correlation of CD4, AST and ALT with age in all the groups (p > 0.05). In conclusion, HBV and HCV co-infected HIV patients are more likely to have a lower CD4+ counts, liver enzyme levels (AST and ALT) than mono-infected HIV patients, highlighting the detrimental impact of these coinfections on immune functions as well as the crucial role of hormonal factors and health-seeking behaviors on the clinical outcomes of liver enzymes among the co-infected patients.

The burden, clinical features and outcomes of SARS-CoV-2, Influenza and co-infections during concurrently out-of-season outbreaks in Brazil

Little is known about the burden and the clinical presentation and prognosis of individuals with Influenza and SARS-CoV-2 during concurrent outbreaks. We aimed to describe the burden, clinical characteristics and outcomes of hospitalized adults during the Influenza A/H3N2 and Omicron outbreaks in Brazil. Cross-sectional analysis of national surveillance data. We described the health system burden and clinical features of confirmed cases of Influenza and/or SARS-CoV-2 reported in the national surveillance system during the Influenza A H3N2 out-of-season outbreak and the first Omicron surge between November 2021 and March 2022 in Brazil. A multilevel mixed-effects logistic regression model adjusted by a priori defined confounders was used to evaluate the association between the infection type and resource use and mortality. The outbreaks occurred simultaneously across all Brazilian regions. Coinfected patients had clinical features from both infections. Influenza coinfected cases had similar odds for requiring ICU admission (adjusted odds ratio, aOR 0.96, 95% CI, 0.80-1.15, p=0.634), mechanical ventilation (aOR 0.88, 95% CI, 0.70-1.11, p=0.290), and in-hospital mortality (aOR 1.02, 95% CI, 0.84-1.23, p=0.847) compared to COVID-19 only. Influenza had lower odds for requiring ICU admission, mechanical ventilation and in-hospital mortality compared to COVID-19 only. Simultaneous surges of Influenza and SARS-CoV-2 increased the pressure on the health system of Brazil. Coinfection was not associated with higher resource use or death; Influenza was associated with better outcomes, compared to COVID-19.

Cost analysis of hidden hepatitis D virus infection in Spain.

A significant percentage of patients coinfected with hepatitis B virus (HBV) and hepatitis D virus (HDV) are undiagnosed. Coinfected patients progress to advanced liver disease faster than HBV monoinfected patients, thereby consuming more healthcare resources. The aim was to perform an analysis to determine the cost of hidden HDV infection in Spain. An analytical model was developed to estimate the prevalence of hidden HDV infection with/without advanced liver disease at the time of diagnosis. An epidemiological flow chart was established to quantify undiagnosed chronic hepatitis D patients. The percentages of patients with compensated cirrhosis (CC), decompensated cirrhosis (DC), hepatocellular carcinoma (HCC) and requiring liver transplantation (LT) and their annual costs were subsequently obtained from the literature. Direct healthcare costs were considered within a time horizon of 1 year. For patients without advanced disease, the consumption of healthcare resources was obtained from a experts panel. A total of 2,180 patients with hidden HDV infection were estimated; of these, 1,188 (54%) had advanced liver disease (29%-CC, 57%-DC, and 8%-HCC) or underwent LT (6%), and 992 (46%) patients did not have advanced disease. The total annual cost of hidden HDV would be euro 17.8 million (euro 16.9 million with advanced disease and euro 882,400 for those without). Hidden HDV infection represents a high economic burden in Spain due to the rapid progression of liver disease in affected patients. These results highlight the importance of early diagnosis to prevent future clinical and economic burden related to liver disease progression.

Daily activities change is linked to acute angle closure occurrence in COVID-19 co-infected patients.

To analyze the influence of daily activity-related factors associated with COVID-19 infection on the occurrence of acute angle closure (AAC). A multicenter hospital-based study was conducted at 23 ophthalmic centers in 17 provincial-level regions across China to recruit patients with confirmed AAC during the post-lockdown time of COVID-19 (P-TOC) from Dec 7, 2022, to Jan 17, 2023, and three lockdown time of COVID-19 (TOC) periods, which included the TOC-2022 (Sep 7, 2022 - Dec 6, 2022), TOC-2021(Sep 7, 2021 - Jan 6, 2022) and TOC-2020 (Sep 7, 2020 - Jan 6, 2021). Patient information, including demographic, a questionnaire on daily activity changes during the AAC period, COVID-19 history, and eye examination results, was collected. The study involved 3216 AAC cases, with 76.2% being female and 78.9% aged over 60 years. AAC occurrences during P-TOC was nearly tripled compared to the corresponding months in TOC-2021 and TOC-2020. Patients with AAC comorbidity and COVID-19 had significantly higher water intake (37.3% vs. 2.2%, p < 0.001) and poorer sleep quality (49.16% vs. 4.07%, p < 0.001) than those without COVID-19 comorbidity, while about 58.4% of these patients received antipyretic analgesic drugs for symptom management. The COVID-19 group showed higher intraocular pressure as well as worse uncorrected distance visual acuity, when compared to non-COVID-19 patients. The relationship between AAC occurrence and daily activity factors associated with COVID-19 suggests that patient management should account for changes in daily activities.

Risk factors for hepatocellular carcinoma in cirrhosis: A comprehensive analysis from a decade-long study

BACKGROUND Cirrhosis is a significant risk factor for the development of hepatocellular carcinoma (HCC). Variability in HCC risk among patients with cirrhosis is notable, particularly when considering the diverse etiologies of cirrhosis. AIM To identify specific risk factors contributing to HCC development in patients with cirrhosis. METHODS This retrospective study analyzed data from cirrhotic patients at Beijing Youan Hospital from January 1, 2012 to September 30, 2022 with at least 6 mo of follow-up. Patient demographics, medical histories, etiologies, and clinical characteristics were examined. Cox regression analysis was used to analyze correlations of the above parameters with hepatocarcinogenesis, while competing risk regression was used to estimate their adjusted hazard ratios accounting for death. The cumulative incidence was plotted over time. RESULTS Overall, 5417 patients with cirrhosis (median age: 54 years; 65.8% males) were analyzed. Hepatitis B virus (HBV) was the most common etiology (23.3%), with 25% (n = 1352) developing HCC over a 2.9-year follow-up period. Patients with multiple etiologies had the HCC highest incidence (30.3%), followed by those with HBV-related cirrhosis (29.5%). Significant risk factors included male sex, advanced age, hepatitis C virus (HCV) infection, elevated blood ammonia, and low platelet count. Men had a higher 5-year HCC risk than women (37.0% vs 31.5%). HBV, HCV, and HBV/HCV co-infected patients had 5-year risks of HCC of 45.8%, 42.9%, and 48.1%, respectively, compared to 29.5% in nonviral hepatitis cases, highlighting the significant HCC risk from viral hepatitis, especially HBV, and underscores the importance of monitoring these high-risk groups. CONCLUSION In conclusion, HBV-related cirrhosis strongly correlates with HCC, with male sex, older age, viral hepatitis, elevated blood ammonia, and lower albumin and platelet levels increasing the risk of HCC.

Hepatic Flare Following Effective Antiretroviral Therapy Is Associated With HBsAg Seroclearance in HBV/HIV-1 Co-Infection.

Little is known about the clinical significance of hepatic flare following effective antiretroviral therapy (ART) on HBsAg seroclearance and prognosis in HBV/HIV co-infection. This observational cohort study recruited HBV/HIV-1 co-infected patients from the China National Free Antiretroviral Treatment Program. We obtained longitudinal information on demographic characteristics, clinical indicators, and treatment outcomes. Hepatic flare was defined as an elevation of ALT of more than five times the upper limit of the normal range without an upsurge of HBV DNA or HBsAg at any time point between ART initiation and 12 months. Among the 1354 enrolled patients, 98.7% received two anti-HBV drugs containing ART and 95.1% achieved good viral control. Hepatic flare was observed in 88 (6.5%) patients and was more frequent in those with lower baseline immune function but subsequently enhanced immune reconstitution. Over a median follow-up of 4.7 years, we observed 99 HBsAg seroclearance, 9 hepatic events, 6 HIV-associated malignancy, 3 non-HIV-associated malignancy, and 3 all-cause mortality. The 3-, 5-, and 10-year cumulative incidence of HBsAg seroclearance was 6.4%, 8.9%, and 12.9%, respectively. Compared to patients without hepatic flare, patients with hepatic flare had significantly higher rates of HBsAg seroclearance (13.6% vs. 6.9%, p = 0.018) but had no recorded adverse outcome. Multivariate analysis with different models indicated that hepatic flare was independently associated with HBsAg seroclearance especially in patients with low immune function, normal ALT, and high levels of HBV DNA and HBsAg at baseline. In HBV/HIV-1 co-infection, hepatic flare following effective ART is associated with HBsAg seroclearance. HBV-specific T cells immune reconstitution may represent a potential mechanism which deserves further investigation.

Evolution of Hematobiochemical Profiles in Newly Diagnosed HIV Patients and HIV-TB Co-Infected Patients: Correlation with Immunological and Virological Status.

CD4+ cells, HIV-1 plasma viral load (PVL), and IFN-γ have been observed to enhance susceptibility in TB infection/reactivation among HIV-1 infected people, leading to unusual clinical manifestations. HIV-TB co-infection is significant for immunological and virological response, making it a great clinical challenge for patient management. The objective of this study was to explore the correlation among various hematological and biochemical profiles with CD4+ count and PVL in order to decipher mechanisms of TB development or reactivation in HIV-infected patients. In this cross-sectional study, we included 200 newly diagnosed treatment naïve HIV-1 infected patients, of which 118 were HIV-TB co-infected and 82 were HIV-alone. The CD4+ T count was determined using the BD FACS Count System, and the plasma HIV-1 viral load was estimated using the Abbott m2000 real-time platform. The hematobiochemical testing was performed on fully-automated analyzer ADVIA® 560 and Cobas® 501 Roche Diagnostics. Statistical software SPSS-2, Spearman correlation analysis was used for data analysis and a P-value less than 0.05 was considered statistically significant. Declined hemoglobulin level positively correlated with CD4 counts (r = 0.229; p = 0.001), and a negative correlation was observed with HIV-1 plasma viral load (r = -0.171; p = 0.016). Moreover, the CD4+ count and HIV-1 plasma viral load (PVL) were also correlated to anomalies such as thrombocytopenia, leucopenia, eosinophils, neutrophils, ESR, potassium, Albumin, globulin, SGOT, uric acid. Studies also found significantly higher absolute neutrophil count, ESR, and serum fasting blood sugar, creatine, uric acid, total bilirubin, globulin, and alkaline phosphatase in HIV-TB co-infected patients. The initial value of Hb, ESR, absolute neutrophil counts, serum calcium, uric acid, and potassium can be used as an early indicator for active tuberculosis (TB) and as a substitute marker for the course of HIV disease, especially in areas with low resources.

Higher levels of IL-6 and IL-10 cytokines in visceral leishmaniasis-HIV co-infected patients from Brazilian high endemic area

Visceral Leishmaniasis (VL) is an endemic disease in Latin America, and the clinical outcome worsens when a patient has HIV co-infection. In these patients, the immune response is complex and cytokines profile variable. We evaluate Th1/Th2/Th17 cytokine profile in VL/HIV patients from Brazilian high endemic area. In this cross-sectional study, the serological cytokines production was compared with clinical and epidemiological traits of the VL/HIV, VL and HIV patients. VL/HIV patients are predominantly male (89.2 %) with relapses in 35.5 % of the cases. There is higher serum levels of IL-6 (p = 0.006) and IL-10 (p < 0.001) in VL/HIV patients. Furthermore, there is a moderate or strong positive correlation in the serum levels of IL-6 and TNF-α (Rho = 0.635, p < 0.001), IL-10 and IFN-γ (Rho = 0.523, p < 0.001), IL-6 and IL-10 (Rho = 0.506, p < 0.001), IL-2 and IL-4 (Rho = 0.506, p < 0.001). Then, VL/HIV patients who died during VL treatment (p = 0.033), patients with oedema (p = 0.011), and patients with jaundice (p = 0.019) had statistically high levels of IL-6. In conclusion, VL/HIV patients have production or reduction of specific cytokines, highlights IL-6 and IL-10.

Hepatitis B Virus Prevalence and Genotype Distribution in Human Immunodeficiency Virus Infected Patients from Brazzaville, Republic of the Congo

Hepatitis B virus infection is a major global health problem, particularly in HIV-infected patients and increases the risk of liver damage. The purpose of this study was to assess the HBV prevalence and genotypes among HIV-infected patients in Brazzaville, Republic of the Congo. This cross-sectional study was conducted among HIV-positive patients attending an outpatient treatment center for HIV/AIDS in Brazzaville, from June 2018 to February 2020. Blood samples were screened for HBsAg by ELISA and HBV genotypes were determined by phylogenetic inference. Data analysis was done using SPSS V.21.0 and P value less than 0.05 was considered as statistically significant. A total of 275 patients HIV-infected were included. The prevalence of HIV-HBV coinfection was 6.9% (95%CI:4.21-10.58). The majority of the co-infected with HBV were mainly male patients (7.7%). HIV-positive individuals aged 28-38 (8.4%) were mostly affected. None of the risk’s factors tested was significantly associated with HBV in HIV-infected patients. Phylogenetic analysis revealed that 9/15 (60%) belonged to genotype E while 6/15 (40%) belonged to genotype A including subgenotypes A3 and A5. In conclusion, these data underline the importance of HBV genotype identification as an integrated measure of HIV routine care to improve the treatment of HIV/HBV co-infected patients.

Expression of anti-HBe in HBeAg and HIVp24 seropositive patients and its relation to antibodies against HIV-specific proteins in Warri, Nigeria

BackgroundCo-infection with hepatitis B virus (HBV) and human immunodeficiency virus (HIV) poses significant clinical challenges, particularly in high-prevalence regions. The presence of anti-HBe antibodies can offer insights into immune responses and disease progression in co-infected patients.ObjectivesThis study aims to investigate the prevalence and clinical significance of anti-HBe antibodies in HBV and HIV co-infected patients in Warri, Nigeria, while analyzing their relationship with HIV-specific antibody profiles.MethodsA cross-sectional study involving 200 HBeAg and HIVp24 seropositive patients was conducted. Blood samples were analyzed for anti-HBe using ELISA, alongside assessments for HBeAg and HIVp24. HIV-specific antibodies were detected using Western blot. Data were analyzed using chi-square tests and logistic regression models (IBM SPSS 23.0).ResultsThe study enrolled 200 patients with dual seropositivity for HBeAg and HIVp24. Among these, 150 patients had confirmed HBeAg positivity, of whom 68 (45%) tested positive for anti-HBe. This presence was significantly associated with HIVp24 positivity (p = 0.04). Anti-HBe levels positively correlated with HIV-specific antibodies, with higher mean anti-HBe expression in patients with antibodies to gp120 (1.8 ± 0.4 AU/mL) and gp41 (1.7 ± 0.3 AU/mL). The odds ratio for anti-HBe presence with HIV-specific antibodies was 2.3 (95% CI: 1.5–3.5, p = 0.008).ConclusionThe findings indicate a prevalent presence of anti-HBe antibodies among HBeAg-positive HIV co-infected patients, highlighting significant correlations with HIV-specific antibodies. This underscores the complex immune interactions between HBV and HIV, emphasizing the need for integrated management strategies and the potential role of anti-HBe as a marker for disease progression.

Tuberculosis treatment outcome of TB/HIV co-infected patients at Adare Hospital, Hawassa City Administration, Sidama Region

BackgroundThere is lack of evidence on the TB treatment outcomes of TB/HIV co-infected patients who received anti-TB treatment in Sidama region. In this study, we aimed to assess the treatment outcome of TB/HIV co-infected patients receiving care at Adare Hospital in Hawasa City, Sidama Region.MethodsA cross sectional study based on retrospective data among TB/HIV co-infected cases was conducted at Adare Hospital. The unit TB registry and antiretroviral therapy (ART) registry were reviewed for the period between September 1, 2016 and August 31, 2022 to measure TB treatment outcomes. Target population for this study was all TB/HIV co-infected cases aged 15 years or more treated at Adare Hospital in the Hawassa City Administration. The data sources for this study were the unit TB register at the TB clinics, patient charts, and the ART register of the facility. Data were entered and analysed using the statistical package SPSS version 26. A summary descriptive analysis was calculated. Bivariable and multivariable analyses were performed to identify associations between variables.ResultsDuring the study period, 298 TB/HIV co-infected cases were treated for TB in the Hospital. Thirty three (11.1%), of the cases had an unfavourable TB treatment outcome. The risk of an unfavourable treatment outcome was over three times higher among re-treated TB cases than among the new TB cases (AOR = 3.3, 95% CI (1.4, 7.9)). The risk of death was higher among stage-IV HIV cases (AOR = 8.1, 95% CI (2.3, 28.9)), and among participants who used non-communicable diseases medications during the cohort period (AOR = 7.3, 95% CI (1.6, 33.6).ConclusionTB treatment success rate among TB/HIV co-infected cases in the current study was comparable to many other reports. There are factors that contributed for unsuccessful TB treatment outcome. Cautious follow-up of cases and managing these factors could help in improving the TB treatment outcome.

Concomitant parasite infections influence tuberculosis immunopathology and favor rapid sputum conversion of pulmonary tuberculosis patients

Immunopathology of human tuberculosis (TB) in a subgroup of patients is characterized by aberrantly high concentrations of inflammatory cytokines, for example Interleukin (IL)-6. Concomitant (co-)infections by parasites can affect host immunity, but the impact on immunopathology in TB patients is poorly defined. Here we characterized a group of patients with TB ( n = 76) from Ghana with different protozoan and helminth co-infections. Plasma cytokines were measured at the onset of disease and anti-mycobacterial treatment efficacy was monitored during disease course. A subgroup of TB patients had co-infections with protozoan (n = 19) or helminth (n = 16) parasites. Plasma analyses for candidate cytokines identified lower levels of IL-6 in parasite co-infected patients with TB. Moreover, it took less time for co-infected patients to become sputum-negative for Mycobacterium tuberculosis during treatment. These results indicated an influence of parasite co-infections on immunopathology in TB and suggested positive effects on treatment efficacy.

Efficacy of 8-week daclatasvir-sofosbuvir regimen in chronic hepatitis C: a systematic review and meta-analysis

BackgroundThe high rates of the sustained virologic response 12 weeks after treatment (SVR12) in real world settings provoked the adoption of shortened courses of the costly direct-acting antivirals (DAAs) regimens. This study provides, to our knowledge, the first systematic review and meta-analysis for the efficacy of the shortened 8-week course of sofosbuvir (SOF) plus daclatasvir (DCV), the most accessible DAAs in the low-middle income countries (LMICs).MethodsWe performed a proportion meta-analysis to determine a reliable rate of SVR12 by pooling all studies that evaluated the results of the 8-week regimen of DCV + SOF. In addition, we applied sensitivity analyses using two imputation paradigms: a conservative approach, and a pragmatic approach to avoid overestimating the efficacy of the 8-week regimen in studies that followed a response-guided treatment (RGT) approach.ResultsSix studies with a total of 159 patients were included. The pooled SVR12 rate ranged from 91 to 97% in the included scenarios. The pragmatic scenario showed that the pooled SVR12 was 97% (95% confidence interval (CI) 91%; 100%) with lower variability as assessed by the prediction interval. The conservative approach revealed an SVR12 of 93% (95% CI 84%; 95%).ConclusionThe 8-week course of 60 mg DCV with SOF provided a comparable SVR12 to the standard 12-week regimen in treatment-naïve, non-HIV co-infected patients with a minimum estimated efficacy of 90%.

Prevalence of Co-infection of Hepatitis B Virus and Hepatitis C Virus among Human Immunodeficiency Virus Patients on Antiretroviral Therapy at A Tertiary Care Centre, Eluru, Andhra Pradesh, India

HIV, HBV, and HCV can form a pretty challenging trio when they coexist. Managing co-infection is crucial for the overall health of the individual, especially considering the potential impact on the liver. Regular monitoring and appropriate medical care can make a significant difference in the outcome for co-infected patients. To ascertain the seroprevalence of HBV and HCV in individuals with HIV attending the Anti-Retroviral Therapy (ART) center affiliated with a tertiary care hospital in Eluru, Andhra Pradesh. Over an 8-month duration, blood samples were obtained from all the individuals visiting the ART Centre. These samples underwent screening for surface antigen of HBV (HBsAg) and antibodies against HCV (anti HCV) by using rapid card tests. Positive samples were subsequently validated through ELISA testing. Baseline CD4 counts, CD4 count after receiving ART were assessed in individuals with HIV alone and those with coinfection of HBV. HIV viral load tests were conducted in individuals with HIV infection and those with coinfection of HBV, assessing their response to ART. Statistical analysis was applied to examine the obtained results. Among the 4382 participants, the seroprevalence of HBV &amp; HCV was 0.02%. The baseline CD4 values averaged 310 for HIV mono-infection cases and 223 for HIV/HBV co-infection cases, indicating a statistically significant distinction with a P value of 0.03. Likewise, the mean values of the CD4 counts after taking ART in individuals with HIV alone and those with coinfection of HBV were 675 and 599, respectively, with a statistically significant P value of 0.05. The study revealed a substantial enhancement in the effectiveness of ART, as indicated by HIV-1 viral load values, in both mono-infection and co-infection cases. Considering the similarity in the main transmission routes of HIV, HBV, and HCV, it is anticipated that hepatotropic viruses would be present in individuals with HIV infection.

Mucosal leishmaniasis of the lips and cheeks: a first concomitant presentation of visceral and mucosal leishmaniasis in a patient living with HIV/AIDS in Monastir, Tunisia

BackgroundVisceral Leishmaniasis (VL) is the most severe and fatal disease if left untreated. In people living with HIV/AIDS (PLHA), VL is considered an emerging opportunistic infection. The aim of this manuscript was to report a first case in Tunisia of a concomitant presentation of visceral and oral leishmaniasis in a patient LHA. A systematic review of the literature was performed according to PRISMA guidelines, as well.Case presentationThe patient, a 43-year-old heterosexual man, treated for HIV/AIDS was referred for macrocheilitis of the upper and lower lips. A noticeable nodular and painless swelling extending to the cheeks’ mucosa was noted. The patient's poor oral hygiene was evident due to the presence of multiple dental caries. Histological analysis of the biopsied lower lip sample revealed the presence of numerous Leishmania amastigotes. The diagnosis of VL was clinically confirmed by the presence of a mild splenomegaly and pancytopenia and biologically by the identification of the parasite using PCR Lei and the species L. infantum involved using RFLP-PCR and culture. The treatment consisted of an intravenous administration of liposomal Amphotericin B (Ambisome®, 40 mg/kg/weight) for a period of 6 weeks. A favorable outcome was noted after one year with the resolution of clinical symptoms and a negative Leishmania blood PCR test. After 2 years, the patient remained asymptomatic but showed a positive Leishmania blood PCR test. Dolutegravir® was introduced in the patient’s ART regimen.ConclusionsTo the best of our knowledge, this is the first case report in Tunisia of atypical VL diagnosed through an uncommon oral location in an HIV/AIDS co-infected patient . Since VL is a severe and potentially fatal disease, it is essential for dentists to perform a thorough clinical examination and adopt a multidisciplinary approach in order to ensure an early diagnosis and an effective treatment outcome.
