A cross-sectional study on co-infection of hepatitis B and hepatitis C among people living with HIV/AIDS from a tertiary care hospital of Central India

Background: Hepatitis B virus (HBV), hepatitis C virus (HCV), and Human immunodeficiency virus (HIV) infections are prevalent throughout the world. HIV infection increases the risk of HBV and HCV liver disease especially when HIV-associated immunodeficiency progresses. Aims and Objectives: This study was carried out with the objectives as follows: Estimation of the prevalence of HIV- Hepatitis co-infection, determine CD4+T lymphocyte count in co-infected patients, identify most common opportunistic infections in HIV – Hepatitis co- infection. Materials and Methods: A hospital-based, prospective, cross-sectional, and observational study was carried among people with confirmed HIV infection. HIV antibody, hepatitis B surface antigen (HBsAg), and HCV antibody tests were done in all patients visiting to integrated counseling and testing center. HIV, HBV, and HCV viral load were done in all serologically confirmed patients. In HBsAg positive patients various markers for hepatitis such as hepatitis B envelop antigen (HBeAg), anti-hepatitis B core antibody (HBcAb), and anti-hepatitis B envelop antibody were also done. Results: Out of 357 people living with HIV/AIDS (PLHA) patients 15/357 (4.20%) were co-infected with HBV, 03/357 (0.84%) were co-infected with HCV. The overall seroprevalence of Hepatitis virus (HBV+HCV) in PLHA patients was found to be 5.04% (18/357). CD4+T lymphocyte count <200 cells/μL was seen in 66/339 (19.4%), 04/15 (26.6%), and 03/03 (100%) patients of HIV mono-infected, HBV co-infected, and in HCV co-infected patients, respectively. HIV Viral load ≤1000 copies/mL was seen in 324 and 15 patients in HIV mono-infected and HIV- hepatitis co-infected patient, respectively. Among PLHA patients who were positive for HBsAg; 46.7% (n=7) patients had HBV viral load >2000 IU/mL. All hepatitis B co-infected patients were positive for HBcAb test; HBeAg was positive in 40% (n=06). All HBeAg positive were having viral load >2000 IU/mL. Conclusion: HIV-infected patients are more prone to hepatitis associated liver diseases and exposure to the HBV infection than the general population.

Normalization of circulating plasma levels of miRNAs in HIV-1/HCV co-infected patients following direct-acting antiviral–induced sustained virologic response

In a previous recent work, we recognized three plasma circulating microRNAs (miRNAs)—miR-100-5p_iso3p:-2, miR-122-5p, and miR-192-5p—that correlate largely with liver fibrosis evolution in human immunodeficiency virus type 1 (HIV-1)/hepatitis C virus (HCV) co-infected patients. Here, we investigated whether levels of these three circulating miRNAs can be associated to liver disease evolution in HIV-1/HCV co-infected patients which have achieved HCV sustained virologic response (SVR) 12 weeks after finishing treatment. Eighty-one chronic HIV-1/HCV co-infected patients were longitudinally recruited at baseline (T0) of DAA therapy and 12 weeks (T12) after finishing therapy. At T0 most of the study patients displayed transient elastography values linked to an advanced stage of liver fibrosis (F0-1 9%, F2 11%, F3 32%, F4 48%). Significant reductions in the levels of circulating miR-100-5p_iso3p:-2, miR-122-5p, and miR-192-5p were detected at T12 in SVR patients, in the overall cohort (P < 0.0001, P < 0.0001, and P = 0.0008, respectively) and in patients with advanced (F3-4) liver fibrosis (p < 0.0001, p < 0.0001, and P = 0.0011, respectively). Of note, no significant reduction in the study miRNA levels was found at T12 in patients who did not achieve SVR (P = 0.8750, P = 0.1250, and P = 0.1260, respectively). HCV-cured patients, in contrast to non-responders, significantly reduced their liver stiffness after two years of achieving SVR (p < 0.0001). DAA-induced SVR is linked with a significant reduction in circulating levels of miR-100-5p_iso3p:-2, miR-122-5p, and miR-192-5p. Our results indicate that miRNA plasma levels may be a useful biomarker of liver damage progression in HIV-1/HCV co-infected individuals that reach DAA-induced SVR.

Factors Associated with Liver Enzyme Abnormalities in HIV-HBV and/or HCV Co-infected Patients in Kinshasa, Democratic Republic of the Congo: Multicenter Cross-sectional Study.

Background and ObjectiveLiver enzyme abnormalities (LEA) are extremely common and sometimes severe in individuals infected with human immunodeficiency virus (HIV), but data for this disorder are lacking in the developing countries. The objective of this study was to identify factors associated with LEA in HIV–hepatitis B virus (HBV)/hepatitis C virus (HCV) co-infected patients in Kinshasa, Democratic Republic of the Congo.MethodsThis cross-sectional analytical study included 180 people living with HIV (PLWHIV) mono-infected or co-infected with HBV/HCV between November 10, 2013 and January 10, 2014 in Kinshasa. Sociodemographic, clinical, biological, serological, and immunological data were analyzed. Levels of serum glutamate oxaloacetate transferase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were determined. Antibody levels were determined using enzyme-linked immunosorbent assay (ELISA).ResultsThe mean age of patients was 44.2±11.0 years; female sex was predominant (76.7%). Co-infection, mainly with HBV, but also HCV, was found in 43 (23.9%) patients. Elevated liver enzymes were found in 77 (42.8%) of the patients. No difference was found in the rate of liver enzyme abnormalities between patients with HIV mono-infection or HIV co-infection (46.7% versus 30.2%, respectively; P=0.08). Factors associated with LEA were age ≥50 years (adjusted odds ratio [OR] 2.7; 95% CI 1.4–5.5), duration of HIV infection >3 years (adjusted OR 2.7; 95% CI 1.4–5.5), and CD4 T cells count ≤303 cells/mm3 (adjusted OR 2.2; 95% CI 1.1–4.5).ConclusionsLiver enzyme abnormalities are frequent in patients co-infected with HIV–HBV/HCV as well as in HIV patients without co-infection. Diagnosis is determined based on age, immunodeficiency, and length of illness.

Impact of direct-acting antiviral regimens on hepatic and extrahepatic manifestations of hepatitis C virus infection

Hepatitis C virus (HCV) is a common cause of liver disease and is associated with various extrahepatic manifestations (EHMs). This mini-review outlines the currently available treatments for HCV infection and their prognostic effect on hepatic manifestations and EHMs. Direct-acting antiviral (DAA) regimens are considered pan-genotypic as they achieve a sustained virological response (SVR) > 85% after 12 wk through all the major HCV genotypes, with high percentages of SVR even in advanced fibrosis and cirrhosis. The risk factors for DAA failure include old males, cirrhosis, and the presence of resistance-associated substitutions (RAS) in the region targeted by the received DAAs. The effectiveness of DAA regimens is reduced in HCV genotype 3 with baseline RAS like A30K, Y93H, and P53del. Moreover, the European Association for the Study of the Liver recommended the identification of baseline RAS for HCV genotype 1a. The higher rate of hepatocellular carcinoma (HCC) after DAA therapy may be related to the fact that DAA regimens are offered to patients with advanced liver fibrosis and cirrhosis, where interferon was contraindicated to those patients. The change in the growth of pre-existing subclinical, undetectable HCC upon DAA treatment might be also a cause. Furthermore, after DAA therapy, the T cell-dependent immune response is much weaker upon HCV clearance, and the down-regulation of TNF-α or the elevated neutrophil to lymphocyte ratio might increase the risk of HCC. DAAs can result in reactivation of hepatitis B virus (HBV) in HCV co-infected patients. DAAs are effective in treating HCV-associated mixed cryoglobulinemia, with clinical and immunological responses, and have rapid and high effectiveness in thrombocytopenia. DAAs improve insulin resistance in 90% of patients, increase glomerular filtration rate, and decrease proteinuria, hematuria and articular manifestations. HCV clearance by DAAs allows a significant improvement in atherosclerosis and metabolic and immunological conditions, with a reduction of major cardiovascular events. They also improve physical function, fatigue, cognitive impairment, and quality of life. Early therapeutic approach with DAAs is recommended as it cure many of the EHMs that are still in a reversible stage and can prevent others that can develop due to delayed treatment.

Single nucleotide polymorphisms in PNPLA3, ADAR-1 and IFIH1 are associated with advanced liver fibrosis in patients co-infected with HIV-1//hepatitis C virus.

Nonalcoholic fatty liver disease (NAFLD), insulin resistance and liver fibrosis are prevalent in individuals co-infected with HIV type 1 (HIV-1)/hepatitis C virus (HCV), even after HCV eradication. Our aim was to evaluate single nucleotide polymorphisms (SNPs) associated with advanced liver fibrosis in HIV-1/HCV co-infected patients. In a cohort of 102 participants, we genotyped 16 SNPs in 10 genes previously associated with NAFLD and the innate immune response and correlated the genotypes with liver fibrosis and fat accumulation. Multinomial logistic regression analysis identified three metabolic parameters that were significantly associated with advanced liver fibrosis (stage F3-F4): albumin [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.69-0.91, P = 0.001], percentage of visceral fat area (PVFA) (OR 1.06, 95% CI 1.01-1.12, P = 0.03) and BMI (OR 1.47, 95% CI 1.22-1.77, P < 0.0001). After adjustment for sex, albumin, PVFA and BMI, we found that three SNPs were significantly associated with advanced fibrosis, one each in PNPLA3/rs738409 (P = 0.016), ADAR-1/rs1127313 (P = 0.029) and IFIH1/rs1990760 (P = 0.033). Our results indicate that genotyping for these SNPs can be a useful predictive tool for liver fibrosis progression and liver fat accumulation in patients co-infected with HIV-1/HCV.

938. Identifying Gaps in the Treatment of Hepatitis C in Patients Co-Infected with HIV in Edmonton, Alberta

BackgroundThe Northern Alberta HIV Program (NAHP) provides care and support for about 2500 HIV positive individuals. Part of the program includes screening and therapy for co-morbidities such as hepatitis C virus (HCV) infection. This study aims to assess the occurrence of HCV co-infection among these patients, determine whether they had received treatment for HCV, and identify patients who are currently viremic so they can be linked to care.MethodsNAHP patients from 2010 to 2019 were linked to their HCV antibody, RNA, and genotyping laboratory testing data from January 1, 2000 to December 31, 2019 as well as HCV medication dispensation data. Each patient’s current and previous state of HCV infection and treatment status was assessed. Chart reviews were conducted for patients presently HCV viremic to assess their HIV care and social determinants.ResultsOf the 2417 NAHP patients, 392 (16.2%) were identified as having been co-infected with HCV at some point between January 1, 2000 to December 31, 2019 and meeting the inclusion criteria. Overall, 198 (50.5%) of the HIV-HCV co-infected patients had received HCV treatment and 232 (59.2%) were no longer viremic at their most recent HCV RNA test. 99 (69.2%) of the 143 HCV viremic patients had a suppressed HIV infection suggesting they are active in their HIV care and good candidates for HCV treatment.Figure 1. 2417 patients in the Northern Alberta HIV Program were evaluated for the presence of an HIV- HCV co-infection. 404 patients were identified as having been HIV-HCV co-infected at some point between January 1, 2000 and December 31, 2019. Figure 2. 404 HIV-HCV co-infected patients from the Northern Alberta HIV Program were assessed for the occurrence of treatment as well as the current status of their HCV infection. 143 patients were found to currently have an active HIV-HCV co-infection. Table 2. Characteristics of HIV-HCV co-infected patients from the NAHP with an active HCV infection (n=143) ConclusionThe NAHP has been successful in identifying and treating many of their HIV HCV co-infected patients, however, there remain patients with viremic HCV. Despite the availability of direct-acting antivirals (DAAs) in Alberta and many of these patients being successfully treated for HIV, a significant proportion of co-infected patients have not initiated HCV treatment The HIV treating physicians of these individuals will be notified and encouraged to assist in getting them linked to HCV care and treatment.Disclosures All Authors: No reported disclosures

Evidence that the second human pegivirus (HPgV-2) is primarily a lymphotropic virus and can replicate independent of HCV replication

ABSTRACT The second human pegivirus HPgV-2 is a novel blood-borne virus that is strongly associated with the hepatitis C virus (HCV) infection. However, the molecular evidence for their association as well as the natural history and tissue tropism of HPgV-2 remain to be elucidated. In this longitudinal study, a total of 753 patients including 512 HIV-1 and HCV co-infected patients were enrolled to characterize the natural history of HPgV-2 infection. Peripheral blood mononuclear cells (PBMCs) and liver biopsies were collected to determine the tissue tropism of HPgV-2 using immunohistochemical staining of the HPgV-2 antigen and in situ hybridization of HPgV-2 RNA. We documented both persistent HPgV-2 infection with the presence of HPgV-2 viral RNA and antibodies up to 4.6 years and resolved HPgV-2 infection, accompanied by a simultaneous decline of anti-HPgV-2 antibodies and clearance of HPgV-2 viremia. Furthermore, we observed the clearance of HCV, but not HPgV-2, by treatment with direct-acting antivirals (DAAs). Biochemical tests and pathological analyses did not reveal any indication of hepatic impairment caused by HPgV-2. HPgV-2 RNA and nonstructural antigen were detected in the lymphocytes, but not in the hepatocytes present in the liver biopsy samples. In addition, both positive- and negative-strand HPgV-2 RNAs were detected in PBMCs, especially in B cells. The present study is the first to provide evidence that HPgV-2 is a lymphotropic, but not a hepatotropic virus and that HPgV-2 replication is independent of HCV viremia. These new findings let us gain insights into the evolution and persistent infection of RNA viruses in humans.

Differential Viral Load of HBV and HCV in Co-infected Patients: A Potential Battle between the Viruses

Viral hepatitis is one of the major health problems in which Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) have the highest affinity to cause chronic liver disease. 5% of the people are infected from HBV and 1% are infected from HCV worldwide. In Pakistan 7.4% of the population is suffering with HBV and HCV (An Overview of Hepatitis B and C in Pakistan). Chronic infection of HBV and HCV leads to slow progressive liver diseases. In a period of 30 years or more, infection can lead to liver cirrhosis, chronic liver failure and hepatocellular carcinoma. Co-infection is more frequent than single infection particularly in areas where these two viruses are endemic. To observe and compare the viral loads of HBV and HCV in co-infected and mono infected patients in Karachi, Pakistan. A total 419 serum samples were collected from suspected patients with HBV and HCV infection. 276 were males and 143 were females, with the age ranging from 10 to 40 years. HBV DNA and HCV RNA were extracted and amplified by Abbott sp2000 and Abbott rt2000 respectively as per the manufacturing protocol. 419 serum samples were screened for HBV and HCV viral load by real time PCR. 276 (66%) were male and 143 (34%) were female. HBV viral load was detected in 157 patients (37.4%), HCV viral load was detected in 86 patients (20%), whereas HBV/HCV Co-infected patients were detected in 89 (21%) patients. In co-infected patients, an HCV viral load of 1000 was 52 (58%) patients. The HBV viral load of 1000 was in 57 (64.04%). 87 (20.76%) of the patients tested negative for both HBV and HCV. Pakistan is a developing country with limited economic and health care resources, low literacy rates and limited awareness about diseases. As HBV and HCV share the same routes of transmission, the chances of co-infection of HBV and HCV are increased. The incidence of co-infection also increases the chances of cancer possibly due to the combined oncogenic action of both viruses. Co-infected patients ranging from 10-40 years old showed that the incidence of infection is higher in younger males as compared to females. This may correlate with more exposure to high risk factors. The HBV viral load was higher than HCV viral load in co-infected patients, indicating that there may be a competition between the two viruses in which HCV is suppressed by HBV.

Effect of Treatment of Hepatitis C by Directly Acting Antivirals (DAA) on Chronic Hepatitis C, B Coinfected Patients

Background: Persons with hepatitis C virus (HCV) who are co-infected with hepatitis B virus (HBV) may be at risk for reactivation of HBV infection during or following HCV treatment. HBV and HCV share similar modes of transmission, and co-infection with the two viruses does occur. Objectives: This study aimed to evaluate the effect of HCV anti-viral treatment (DAAS) on HBV in HCV and HBV Coinfected patients. Patients and methods: The study was performed in Internal Medicine Department (Outpatient Clinic and the Inpatient Ward), Mahalla Hepatology Teaching Hospital, Gharbia, Egypt during the period from August 2016 to November 2017 on 20 HCV and HBV co-infected patients ranged from 18-70 years old. Results: The age of patients ranging from 26 to 65 years old (median 44). Male represent 55% and female represent 45% which showed male predominance. Patients were treated by different types by Hcv antiviral treatment (DAAS) like (SOF+DAC), (SOF+SIM), (SOF+DAC+RBV). At baseline, 12 patients had detectable HBV viral load, 5 Patients had positive (HBsAg) and undetectable HBV viral load and 3 patients had negative (HBsAg) and undetectable HBV viral load. Total number of HBV reactivated cases were 12 patients, 3 of them reactivated by increasing HBV DNA, and 5 of them reactivated by both increasing HBVDNA and ALT flare. Conclusion: HBV reactivation is a severe, life-threatening consequence of chemotherapy and immunotherapy in patients with chronic hepatitis B infection. Reactivation may be associated with DAA therapy in patients with HCV/HBV co-infection. HBV reactivation can be prevented through the use of pretreatment screening and anti-HBV prophylactic treatment.

Phylogenetic analysis of hepatitis C virus among HIV/ HCV co-infected patients in Nigeria.

Hepatitis C virus (HCV) infection has been associated with liver disease including liver cirrhosis and hepatocellular carcinoma (HCC) in chronically-infected persons. However, in HIV/HCV co-infected patients, increased rate of progression to cirrhosis and HCC has been reported. Limited information exists regarding genetic variants of HCV circulating among co-infected patients, which could be important in the design of broadly protective vaccine and management of the disease. Here, we determined the genotypes of HCV isolates circulating among HIV/HCV co-infected patients in Ibadan, southwestern Nigeria. One hundred and twenty-five HIV/HCV IgM positive samples obtained from HIV laboratory, University of Ibadan were used for this study. HCV NS5B gene was amplified using polymerase chain reaction (PCR). The amplified NS5B gene was sequenced using gene specific primers. Twenty isolates were amplified, out of which 13 were successfully sequenced. Phylogenetic analysis of the 13 sequenced isolates showed three HCV subtypes 1a, 3a and 5a belonging to genotypes 1, 3 and 5 respectively. Ten isolates (77%) belong to subtype 5a, followed by 2 isolates (15%) subtype 1a and 1 isolate (8%) was subtype 3a. The predominant HCV genotype was 5, followed by genotype 1 (subtype 1a). The findings, as well as the observed mutations in NS5B gene, indicate the need for screening and monitoring of HIV/HCV co-infected patients. Further study to determine the phylogeny of isolates circulating in other parts of Nigeria will be carried out.

Presence of different hepatitis C virus genotypes in plasma and peripheral blood mononuclear cell samples of Iranian patients with HIV infection.

Due to the similar routes of transmission, individuals infected with the human immunodeficiency virus (HIV) may become infected with the hepatitis C virus (HCV) simultaneously. The aim of this study was to investigate the frequency of HCV co-infection in Iranian individuals with HIV infection, and to genotype HCV in plasma and PBMC specimens of these patients. From September 2015 to October 2016, a total of 140 Iranian individuals with HIV infection were enrolled in this cross-sectional study. The RNA from plasma and PBMC specimens was extracted, and genomic HCV-RNA was amplified using RT-nested PCR with primers that target 5'-UTR. The HCV genotyping used the RFLP technique. To confirm HCV genotype, 10 randomly selected HCV-positive samples were also submitted for sequencing. The mean age of patients was 35.7 ± 13.5 years (range: 1-66). Out of 140 patients, 62 (44.3 %) were positive for anti-HCV antibodies; among these, viral genomic RNA was detected in 34 (24.3%) and 39 (27.9%) of the plasma and PBMC specimens, respectively. The HCV genotyping showed a similar pattern of subtypes 1a (44% vs 46.2%), 3a (32.4% vs 33.3%), and 1b (17.6% vs 17.9%) in all sera and PBMC samples. It is noteworthy that the HCV genotypes in plasma and PBMC specimens of 6 HCV co-infected patients were not the same. This study reveals that HIV/HCV co-infection is high in Iranian patients (44.3%), especially in people who have high-risk factors (83.9%). Also, HIV/HCV co-infected individuals may have dissimilar HCV genotypes in their plasma and PBMC specimens.

Treatment rate for HCV in the direct-acting antivirals era in HIV co-infected patients: data from an Italian cohort.

New direct antiviral agents (DAA) are now effective in hepatitis C virus (HCV) infection; persons living with human immunodeficiency virus (HIV) (PLWH) were undertreated. Aim of this study was to describe the management of HCV treatment in a HIV/HCV cohort during a 16 years period. An electronic review of all HIV patients with >1 clinic check from the year 2000 was made. Demographic, virologic and treatment data were collected. From 2000 to 2015 a total of 2352 PLWH were enrolled; 776 (33%) resulted positive at HCV antibodies, and were mostly genotype 1 and 3. 279/579 (48.2%) were treated, and 170 (29.3% of total, 60.9% of treated) obtained a SVR. Treatment rate for HCV had a significant increase in the 2015 (20.6%, P<0.05 when compared with previous years). SVR rate was significantly improved in the 2015 (P<0.05 when compared with each single previous year). At univariate analysis among the different year group there were significant differences in term of HCV RNA positive patients (P<0.001), number of treated (total) and naïve patients (P<0.001 in each of cases), SVR rate (P<0.001), mortality rate (P=0.003). HCV-Ab positive patients with HCV-RNA not detectable (cured) increased during years. At 2015, 50.4% of the HCV-Ab positive patients resulted to be HCV-RNA negative. In the DAA's era a significant increase in the number of treatments was observed. SVR rate was significantly higher. Treatment rate still remains quite low. More than a half of our population of HCV co-infected patients results to be cured for HCV.

Hepatitis C co-infection is associated with an increased risk of incident chronic kidney disease in HIV-infected patients initiating combination antiretroviral therapy

BackgroundCombination antiretroviral therapy (cART) has reduced mortality from AIDS-related illnesses and chronic comorbidities have become prevalent among HIV-infected patients. We examined the association between hepatitis C virus (HCV) co-infection and chronic kidney disease (CKD) among patients initiating modern antiretroviral therapy.MethodsData were obtained from the Canadian HIV Observational Cohort for individuals initiating cART from 2000 to 2012. Incident CKD was defined as two consecutive serum creatinine-based estimated glomerular filtration (eGFR) measurements <60 mL/min/1.73m2 obtained ≥3 months apart. CKD incidence rates after cART initiation were compared between HCV co-infected and HIV mono-infected patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox regression.ResultsWe included 2595 HIV-infected patients with eGFR >60 mL/min/1.73m2 at cART initiation, of which 19% were HCV co-infected. One hundred and fifty patients developed CKD during 10,903 person-years of follow-up (PYFU). The CKD incidence rate was higher among co-infected than HIV mono-infected patients (26.0 per 1000 PYFU vs. 10.7 per 1000 PYFU). After adjusting for demographics, virologic parameters and traditional CKD risk factors, HCV co-infection was associated with a significantly shorter time to incident CKD (HR 1.97; 95% CI: 1.33, 2.90). Additional factors associated with incident CKD were female sex, increasing age after 40 years, lower baseline eGFR below 100 mL/min/1.73m2, increasing HIV viral load and cumulative exposure to tenofovir and lopinavir.ConclusionsHCV co-infection was associated with an increased risk of incident CKD among HIV-infected patients initiating cART. HCV-HIV co-infected patients should be monitored for kidney disease and may benefit from available HCV treatments.

Depression in HIV and HCV co-infected patients: a systematic review and meta-analysis

The aim of this study was to carry out a systematic review and meta-analysis of the differences in the prevalence of depression and presence of depressive symptoms between HIV/HCV co-infection, HIV mono-infection, and hepatitis C virus (HCV) mono-infection. A systematic electronic search of bibliographic databases was performed to locate articles published from the earliest available online until December 2014. Outcomes of depression were based on clinical interviews and validated self-reported measures of depression/depressive symptoms. Of the 188 records initially screened, 29 articles were included in the descriptive systematic review and six were included in the meta-analysis. The meta-analytic results indicated that, as measured by self-reported measures of depression, HIV/HCV co-infected patients were significantly more likely to report depressive symptoms than either HIV (SMD = .24, 95% CI: .03–.46, p = .02) or HCV mono-infected (SMD = .55, 95% CI: .17–.94, p = .005) patients. The variability of the results of the reviewed studies, largely dependent on the samples’ characteristics and the methods of assessment of depression, suggests that a clear interpretation of how depression outcomes are affected by the presence of HIV/HCV co-infection is still needed. Failing to diagnose depression or to early screen depressive symptoms may have a significant impact on patients’ overall functioning and compromise treatments’ outcomes.

Biochemical profiling of tuberculosis patients co-infected with hepatitis C virus

The present research work was planned to investigate the biochemical parameters in tuberculosis (TB) patients in comparison with healthy individual and TB patients co-infected with hepatitis C virus (HCV). For the study, we determined liver enzymes, serum proteins, hemoglobin photometrically, and erythrocyte sedimentation rate (ESR) by the Westergren method. The results showed a significant ( P &lt;0.05) increase in the level of alanine aminotransferase in the Test group (TB + HCV patients) and the TB control group when compared with the healthy control group. A non-significant ( P &gt;0.05) increase in the level of aspartate aminotransferase was observed in the Test group while a non-significantly ( P &gt;0.05) reduced level was observed in the TB control group when compared with healthy controls. Alkaline phosphatase was increased significantly ( P &lt;0.05) in the Test group but non-significantly ( P &gt;0.05) in the TB control group compared to healthy control group. Significant ( P &lt;0.05) variation in the concentration of serum proteins among different groups in the studied population was also observed. Significant ( P &lt;0.05) variation in hemoglobin concentration was observed only on comparing the Test group with healthy individuals ( P = 0.013). No significant ( P &gt;0.05) variation in serum calcium level was observed among study groups. ESR was found to be lower in the healthy control group while significantly ( P &lt;0.05) increased in the Test and TB control groups. The HCV co-infected patients were investigated through HCV screening by the immunochromatographic method. We concluded that variation in biochemical and hematological parameters observed in the studied population help us to diagnose HCV co-infected TB patients.

Retrospective study of hepatitis C outcomes and treatment in HIV co-infected persons from the Australian HIV Observational Database.

The widespread availability of direct-acting antivirals (DAAs) is expected to drastically improve the treatment uptake and cure rate of hepatitis C virus (HCV). In this paper, rates of and factors associated with HCV treatment uptake and cure in the HIV co-infected population in Australia were assessed before access to DAAs. The medical records of patients in the Australian HIV Observational Database who were reported to be HCV antibody positive from 1999 to 2014 were reviewed for HCV treatment data. Patients with detectable HCV RNA were included in this analysis. Logistic regression models were applied to identify factors associated with treatment uptake and HCV sustained virological response (SVR) 24 weeks' post treatment. The median follow-up time of those with chronic HCV/HIV co-infection was 103 months (interquartile range 51-166 months). Of 179 HCV viraemic patients, 79 (44.1%) began treatment. In the adjusted model, a higher METAVIR score was the only significant factor associated with treatment uptake (odds ratio (OR) 8.87, 95% confidence interval (CI) 2.00-39.3, P=0.004). SVR was achieved in 37 (50%) of 74 treated patients. HCV genotypes 2/3 compared with 1/4 remained the only significant factor for SVR in an adjusted multivariable setting (OR 5.44, 95% CI 1.53-19.4, P=0.009). HCV treatment uptake and SVR have been relatively low in the era of interferon-containing regimens, in Australian HIV/HCV coinfected patients. With new and better tolerated DAAs, treatment of HCV is likely to become more accessible, and identification and treatment of HCV in co-infected patients should become a priority.

Magnitude of Hepatitis B Virus and Hepatitis C Virus among HAART Taking Patients and Association with Liver and Renal Function and CD4+ T Cells Level

Background: 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 this study was to assess the magnitude of HBV and HCV infection and its association with liver and renal function, and CD4+ T cell levels of highly active anti-retroviral therapy (HAART) taking patients. Method: A hospital based cross sectional study was conducted at Zewditu Memorial Hospital. Participants’ sociodemographic and clinical information were collected from the anti-retroviral therapy (ART) database. Blood samples were collected from 384 volunteer, patients taking HAART for at least 1 year to investigate CD4, HBSAg, HCVAb, liver and renal function. Data was entered and analyzed by SPSS version 20 and p value less than 0.05 was taken as statistically significant. Results: Of the 384 participants, 222 (57.81%) were females, and 168 (43.75%) were in age group 30-39 years. Overall burden of HBV and HCV were 21 (5.7%). Co-infection rates of HBV-HIV, HCV-HIV and HBV-HCV-HIV were 18 (4.7%), 4 (1%) and 1 (0.2%), respectively. Co-infected study participants had significantly raised mean liver enzyme levels (AST, ALT and ALP) than mono-infected ones. There was no statistically significant difference for renal function parameters between mono-infected and co-infected HAART taking patients. Co-infected HIV patients had lower mean level of CD4 compared to mono-infected ones. Conclusion: HBV and HCV co-infected HIV patients are more likely to have abnormal liver enzyme levels and tend to have low mean CD4 count than mono-infected HIV patients. Large scale cohort study is recommended for consolidating the current findings.

Treatment optimization for HIV/HCV co-infected patients.

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections affect millions of persons around the globe and cause profound morbidity and mortality. A major intersection exists between these two epidemics, with HCV infection being more common in persons with HIV than in the general population, largely due to shared routes of transmission. HCV co-infection increases risk for liver- and non-liver-related morbidity and mortality, making HCV treatment a priority in HIV co-infected persons, but the treatment of HCV in co-infected patients has been daunting for multiple reasons. Until recently, HCV treatment has frequently been deferred due to the low rates of cure, significant adverse effects, burdensome duration of therapy and drug-drug interactions with HIV antiretroviral medications. Untreated HCV has resulted in significant health consequences for the millions of those infected and has led to multiple downstream impacts on our healthcare systems around the world. The development of a remarkable number of new HCV direct-acting agents (DAAs) that are significantly more efficacious and tolerable than the previous interferon-based regimens has transformed this important field of medicine, with the potential to dramatically reduce the burden of infection and improve health outcomes in this population. This review will summarize the epidemiology and clinical impact of HIV/HCV co-infection and current approaches to the treatment of HCV in HIV/HCV co-infected patients.

Boceprevir plus pegylated interferon/ribavirin to re-treat hepatitis C virus genotype 1 in HIV–HCV co-infected patients: final results of the Spanish BOC HIV–HCV Study

Boceprevir (BOC) was one of the first oral inhibitors of hepatitis C virus (HCV) NS3 protease to be developed. This study assessed the safety and efficacy of BOC+pegylated interferon-α2a/ribavirin (PEG-IFN/RBV) in the retreatment of HIV-HCV co-infected patients with HCV genotype 1. This was a phase III prospective trial. HIV-HCV (genotype 1) co-infected patients from 16 hospitals in Spain were included. These patients received 4 weeks of PEG-IFN/RBV (lead-in), followed by response-guided therapy with PEG-IFN/RBV plus BOC (a fixed 44 weeks was indicated in the case of cirrhosis). The primary endpoint was the sustained virological response (SVR) rate at 24 weeks post-treatment. Efficacy and safety were evaluated in all patients who received at least one dose of the study drug. From June 2013 to April 2014, 102 patients were enrolled, 98 of whom received at least one treatment dose. Seventy-three percent were male, 34% were cirrhotic, 23% had IL28b CC, 65% had genotype 1a, and 41% were previous null responders. The overall SVR rate was 67%. Previous null-responders and cirrhotic patients had lower SVR rates (57% and 51%, respectively). Seventy-six patients (78%) completed the therapy scheme; the most common reasons for discontinuation were lack of response at week 12 (12 patients) and adverse events (six patients). Response-guided therapy with BOC in combination with PEG-IFN/RBV led to an overall SVR rate of 67%, but an SVR rate of only 51% in patients with cirrhosis. The therapy was generally well tolerated. Although the current standards of care do not include BOC+PEG-IFN/RBV, the authors believe that this combination can be beneficial in situations where new HCV direct antiviral agent interferon-free therapies are not available yet.
