Abstract
Background Combination of tenofovir disoproxil fumarate (TDF), lamivudine (3TC) and efavirenz (EFV) is preferred in the treatment of HIV/hepatitis B virus (HBV) coinfection. We postulated that a HBV active nucleoside reverse transcriptase (RT) inhibitor/nucleotide RT inhibitor backbone of adefovir dipivoxil (ADV) +3TC would be as effective as TDF +3TC for the Indian population. Objective ADV + 3TC could be an alternative option for these HIV/HBV coinfected individuals, preserving the dually active TDF + 3TC as second-line nucleoside backbone following failure of the first-line ART. Materials and Methods This randomised control trial (CTRI/2012/03/002471) was carried out at the ART Centre of Calcutta School of Tropical Medicine, India. Seventy-eight (39 on each arm) treatment-naïve HIV/HBV coinfected patients were randomised to receive either the combination of lamivudine + tenofovir + EFV or lamivudine + adefovir + zidovudine + EFV and followed up for 120 weeks. Results Median age of the study participants was 36 years (21-62), majority were male (61/78; 78.2%) and heterosexually (39/78; 50%) infected. Baseline characteristics were identical in both arms. There was no statistically significant difference in median aspartate aminotransferase (37 vs. 29.5 U/L), alanine aminotransferase (ALT) (36 vs. 34.5 U/L), ALT normalisation rate (80 vs. 70%), AST to platelet ratio index (0.45 vs. 0.33), CD4 count (508 vs. 427 cells/mm3), HBV DNA suppression (81.8 vs. 70%), hepatitis B e antigen loss (9 vs. 5%), hepatitis B surface antigen seroclearance rate (6.06 vs. 18.75%) and death (3 vs. 3) at 120 weeks between TDF (n = 33) and ADV (n = 32), respectively. Conclusions Adefovir plus lamivudine is an effective alternative of tenofovir plus lamivudine in long-term HBV treatment outcome in HIV/HBV coinfected patients.

Abstract
BACKGROUND Currently, there is no consensus on the efficacy and safety of lamivudine (LAM) plus tenofovir disoproxil fumarate (TDF) combination therapy versus lamivudine monotherapy in HBV/HIV coinfected patients. METHODS A comprehensive literature search was performed in English and Chinese databases. Both relevant dichotomous and continuous variables were extracted, and the combined outcomes were expressed as a risk ratio (RR) or a standard mean difference (SMD). RESULTS Eleven eligible studies were included in our analysis. For HBV-relevant outcomes, the proportion of patients with undetectable HBV, the rates of serum alanine aminotransferase (ALT) normalization and hepatitis B e antigen (HBeAg) loss were higher in the combination therapy group than the monotherapy group (RR = 1.42, 95% CI: 1.14-1.76, P = 0.002; RR = 1.36, 95% CI: 1.17-1.58, P < 0.0001; RR = 2.74, 95% CI: 1.20-6.22, P = 0.02). In addition, the rate of HIV RNA-negative conversion was higher in the combination therapy group than the monotherapy group (RR = 1.26, 95% CI: 1.11-1.42, P = 0.0003). CONCLUSION LAM plus TDF combination therapy was more efficacious than LAM monotherapy in HBV/HIV coinfected patients. As time passes, this difference becomes more pronounced.

Abstract
BACKGROUND Hepatitis B (HBV)-HIV coinfection is associated with liver inflammation, which can progress to liver fibrosis/cirrhosis and hepatocellular carcinoma. We determined HBV seroprevalence in children and adolescents participating in the TREAT Asia Pediatric HIV Observational Database. METHODS A multisite cross-sectional study was conducted in HIV-infected patients currently <25 years old receiving antiretroviral treatment (ART) who had HBV surface antigen (HBsAg), or HBV surface antibody (anti-HBs) or HBV core antibody (anti-HBc) tested during 2012-2013. HBV coinfection was defined as having either a positive HBsAg test or being anti-HBc positive and anti-HBs negative, reflective of past HBV infection. HBV seroprotection was defined as having a positive anti-HBs test. RESULTS A total of 3380 patients from 6 countries (Vietnam, Thailand, Cambodia, Malaysia, Indonesia and India) were included. The current median (interquartile range) age was 11.2 (7.8-15.1) years. Of the 2755 patients (81.5%) with HBsAg testing, 130 (4.7%) were positive. Of 1558 (46%) with anti-HBc testing, 77 (4.9%) were positive. Thirteen of 1037 patients with all 3 tests were anti-HBc positive and HBsAg and anti-HBs negative. One child was positive for anti-HBc and negative for anti-HBs but did not have HBsAg tested. The prevalence of HBV coinfection was 144/2759 (5.2%) (95% confidence interval: 4.4-6.1). Of 1093 patients (32%) with anti-HBs testing, 257 (23.5%; confidence interval: 21.0-26.0) had positive tests representing HBV seroprotection. CONCLUSIONS The estimated prevalence of HBV coinfection in this cohort of Asian HIV-infected children and adolescents on ART was 5.2%. The majority of children and adolescents tested in this cohort (76.5%) did not have protective HBV antibody. The finding supports HBV screening of HIV-infected children and adolescents to guide revaccination, the use of ART with anti-HBV activity and future monitoring.

Abstract
Background HIV co-infection exacerbates hepatitis C disease, increasing the risk of cirrhosis and hepatitis C-related mortality. Combination antiretroviral therapy (cART) is the current standard treatment for co-infected individuals, but the impact of cART and antiretroviral (ARV) monotherapy on liver disease in this population is unclear. We aimed to assess the effect of cART and ARV monotherapy on liver disease progression and liver-related mortality in individuals co-infected with HIV and chronic hepatitis C. Methods A systematic review with meta-analyses was conducted. MEDLINE and EMBASE bibliographic databases were searched up to September 2015. Study quality was assessed using a modified Newcastle-Ottawa scale. Results were synthesised narratively and by meta-analysis. Results Fourteen observational studies were included. In analyses that adjusted for potential confounders, risk of liver-related mortality was significantly lower in patients receiving cART (hazard ratio/odds ratio 0.31, 95 % CI 0.14 to 0.70). Results were similar in unadjusted analyses (relative risk 0.40, 95 % CI 0.29 to 0.55). For outcomes where meta-analysis could not be performed, results were less consistent. Some studies found cART was associated with lower incidence of, or slower progression of liver disease, fibrosis and cirrhosis, while others showed no evidence of benefit. We found no evidence of liver-related harm from cART or ARV monotherapy compared with no HIV therapy. Conclusions cART was associated with significantly lower liver-related mortality in patients co-infected with HIV and HCV. Evidence of a positive association between cART and/or ARV monotherapy and liver-disease progression was less clear, but there was no evidence to suggest that the absence of antiretroviral therapy was preferable.

Abstract
A large number of people living with HIV/AIDS residing in HBV endemic regions such as in India are highly susceptible to acquire co-infections like HBV but also transmit them to other due to their high risk behaviours. The present study aimed to estimate HBV prevalence and distribution of various HBV serological markers among HIV infected individuals. This cross sectional survey covered HIV infected individuals attending the largest HIV care center in India. Socio-demographic details and blood samples to screen for HBV seromarkers using commercial ELISA kits were collected. Among 1160 HIV infected patients, prevalence of HBcAb, HBsAb, HBsAg and HBeAg was 66, 29.4, 16.6 and 5.8 % respectively. Overall, 28.9 % individuals had no evidence of any of the four markers, indicating lack of previous exposure and future risk of acquiring HBV infection. Presence of anti-HBsAg in a mere 0.9 % of individuals reflected low levels HBV vaccine conferred immunity which could be due to poor HBV vaccine coverage in this high risk population. With high prevalence and evidence of exposure to HBV as well as considering the growing literature on increase in hepatic complications in HIV-HBV co-infected individuals, the need for mandatory HBV screening of all HIV infected individuals cannot be over-emphasised. The policy makers and HIV programme managers must consider HBV vaccination for newly detected HBV naive HIV infected individuals and also focus on creating public awareness on HBV and HIV prevention.

Abstract
PURPOSE OF REVIEW Coinfection with hepatitis C virus (HCV) and HIV is a significant public health problem worldwide. The broad spectrum antivirals interferon-alpha (IFN) and ribavirin (RBV) have lower sustained virologic response rates in HIV-HCV coinfection compared with HCV monoinfection, with significant associated toxicities and prolonged treatment courses. The recent availability of direct acting antivirals (DAA) has transformed the treatment of HCV, with the opportunity of cure available for most patients with much more tolerable regimens. These regimens are now being studied in HIV-HCV coinfection. RECENT FINDINGS DAA-based regimens for HIV-HCV coinfection have shown excellent efficacy, with cure rates similar to HCV monoinfection. Either in combination with IFN and RBV, or in 'IFN-free' regimens, cure rates of over 90% are the goal for all HIV-HCV-infected individuals. Data are excellent in genotype 1 infection, but further data on genotype 2-6 are required. These regimens have been shown to be cost-effective in HCV monoinfection, and are likely to be cost-effective in HIV-HCV coinfection. Nonetheless they remain expensive. Recent guidelines have identified coinfected patients as a group for prioritization for treatment, regardless of fibrosis stage. Earlier treatment of those likely to transmit HCV is also recommended. SUMMARY With the use of DAA, HCV infection in HIV should be curable for most patients, and HIV-infected patients should be prioritized for treatment. The optimal treatment regimens for some genotypes have yet to be determined. The significant cost of DAA-containing regimens is likely to significantly impair their widespread use for the short to medium term, even in well resourced settings, and those with more advanced liver disease are likely to access them first.

Abstract
Background There is strong evidence that post-exposure prophylaxis (PEP) with antiretroviral drugs in the timely management of occupational exposures sustained by healthcare workers decreases the risk of HIV infection and PEP is now widely used. Antiretroviral drugs have well documented toxicities and produce adverse events in patients living with HIV/AIDS. In the era of “highly active antiretroviral therapy”, non-adherence to treatment has been closely linked to the occurrence of adverse events in HIV patients and this ultimately influences treatment success but the influence of adverse events on adherence during PEP is less well studied. Methods Following the introduction of a HIV post-exposure prophylaxis program in the Korle-Bu Teaching Hospital in January 2005, the incidence of adverse events and adherence were documented in occupationally-exposed healthcare workers (HCWs) and healthcare students (HCSs). Cohort event monitoring was used in following-up on exposed HCWs/HCSs for the two study outcomes; adverse events and adherence. All adverse events reported were grouped by MedDRA system organ classification and then by preferred term according to prophylaxis regimen. Adherence was determined by the completion of prophylaxis schedule. Cox proportional regression analysis was applied to determine the factors associated with the cohort study outcomes. Differences in frequencies were tested using the Chi square test and p < 0.05 was considered statistically significant. Results A total of 228 exposed HCWs/HCSs were followed up during the study, made up of 101 exposed HCWs/HCSs administered lamivudine/zidovudine (3TC/AZT) for 3 days; 75 exposed HCWs/HCSs administered lamivudine/zidovudine (3TC/AZT) for 28 days; and 52 exposed HCWs/HCSs administered lamivudine/zidovudine/lopinavir-ritonavir (3TC/AZT/LPV-RTV) for 28 days. The frequency of adverse events was 28 % (n = 28) in exposed HCWs/HCSs administered 3TC/AZT for 3 days, 91 % (n = 68) in exposed HCWs/HCSs administered 3TC/AZT for 28 days and 96 % (n = 50) in exposed HCWs/HCSs administered 3TC/AZT/LPV-RTV for 28 days. Nausea was the most commonly reported adverse events in all three regimens. Adherence was complete in all exposed HCWs/HCSs administered 3TC/AZT for 3days, 56 % (n = 42) in exposed HCWs/HCSs administered 3TC/AZT for 28 days and 62 % (n = 32) in exposed HCWs/HCSs administered 3TC/AZT/LPV-RTV for 28 days. In the Cox regression multi-variate analysis, exposed HCWs/HCSs administered 3TC/AZT for 3 days were 70 % less likely to report adverse events compared with exposed HCWs/HCSs administered 3TC/AZT for 28 days (Adjusted HR = 0.30 [95 % CI, 0.18-0.48], p < 0.001). Exposed HCWs/HCSs administered 3TC/AZT for 3 days were 75 % more likely to adhere to the schedule compared with exposed HCWs/HCSs administered 3TC/AZT for 28 days (Adjusted HR = 1.75 [95 % CI, 1.16-2.66], p = 0.008). Conclusion The intolerance to adverse events was cited as the sole reason for truncating PEP, thereby indicating the need for adequate, appropriate and effective counselling, education, active follow-up (possibly through mobile /phone contact) and management of adverse events. Education on the need to complete PEP schedule (especially for exposed HCWs/HCSs on 28-day schedule) can lead to increased adherence, which is very critical in minimizing the risk of HIV sero-conversion. The present results also indicate that cohort event monitoring could be an effective pharmacovigilance tool in monitoring adverse events in exposed HCWs/HCSs on HIV post-exposure prophylaxis.

Abstract
The number of HIV-positive people aged ≥50 years is rising each year. We measured the prevalence of non-infectious illnesses and their risk factors and described healthcare use in this UK population. A cross-sectional, observational study was conducted at an outpatient HIV specialist clinic in south east England. Patients age ≥50 years were invited to complete questionnaires measuring demographics, non-infectious illnesses, medication use, lifestyle and healthcare utilisation. The response rate was 67%. Of 299 participants, 84% reported ≥1 comorbid condition and 61% reported ≥2 (multimorbidity). Most commonly reported were high cholesterol, sexual dysfunction, hypertension and depression. In multivariate analyses, age, number of years HIV-positive and duration of antiretroviral therapy remained significant predictors of comorbidity when controlling for lifestyle factors (exercise, smoking and use of recreational drugs and alcohol). Use of non-HIV healthcare services was associated with increasing comorbidity, a longer duration of HIV and recreational drug use. The majority of HIV-patients aged ≥50 years reported multiple comorbidities and this was associated with polypharmacy and increased use of non-HIV services. Further research examining the quality, safety and patient experience of healthcare is needed to inform development of services to optimally meet the needs of older HIV-positive patients.

Abstract
Coinfections of sexually transmitted infections are frequent due to the same transmission routes which may facilitate the transmission of other sexually transmitted infections. Sexually transmitted coinfections are associated with atypical and generally more severe clinical features, more complications, resistency to treatment, unfavourable outcome, and worse prognosis. Sexually transmitted infections may increase the likelihood of acquiring and transmission of HIV infection. The authors summarize the most important characteristics of sexually transmitted infections (such as HIV and hepatitis B virus, HIV and hepatitis C virus, HIV and syphilis, HIV and gonorrhoeae, HIV and chlamydia coinfections). These infections are more frequent in HIV infected patients than in the normal population. The shared transmission routes, impairment of the immune response, elevated cytokine levels and the associated inflammatory milieu produce local tissue damage, breaches in mucosal epithelium, which increases the risk of human immunodeficiency virus infection. Regular screening for sexually transmitted infections, use of more sensitive diagnostic methods, improved reporting and avoidance of unsafe sexual behaviour among certain subpopulations as well as education are essential in the prevention of sexually transmitted coinfections.

Abstract
Tenofovir disoproxil fumarate (TDF) is approved by the Food and Drug Administration for use in children ages 2 years and older and is recommended by the World Health Organization for use as a preferred first-line nucleotide reverse transcriptase inhibitor in adults and adolescents ages 10 years and older. The simplicity of once daily dosing, few metabolic side effects and efficacy against hepatitis B virus make TDF suitable for use in a large scale program. Unlike thymidine analoge nucleoside reverse transcriptase inhibitors (NRTIs); tenofovir does not induce multi-NRTI resistance mutations, so more NRTI options are available for future second-line-regimens. Fixed-dose combinations of TDF with other ARVs as a single tablet regimen are now widely available for adults and adolescents, but none are available for young children. Current information on TDF including the pharmacokinetics, safety and tolerability in children and adolescents was reviewed. A dosing regimen according to body-weight-band has been established for pediatric use. Safety concerns of TDF mainly relate to its effects on renal function and bone mineral density. Regular monitoring of renal function in high-risk patients, including those on other nephrotoxic drugs, may be warranted to detect adverse renal effects. Long-term-data on renal and bone outcomes among HIV-infected children is needed. Lessons learned from clinical studies will help clinicians balance the risks and benefits of TDF and design appropriate antiretroviral regimens for children in different circumstances.

Abstract
This study examined the HIV patients' attitudes towards the practice of organ transplant between HIV patients using a cross-sectional survey design. In total, 206 patients participated with a mean age of 42 (±8.8) years. The majority (70%) were black African and women (54%), and 83% described themselves as heterosexual. Most participants (n = 171, 83%) were on treatment, and 159 (93%) had viral load less than 40 copies/ml. Mean duration of illness and mean duration of treatment were 77 (±42.7) and 68 (±41) months, respectively. Of all participants, 128 (62%) reported that they would consider donating either any organ or a specific organ/s to an HIV patient, 33 (16%) would not consider it and 45 (22%) were unsure about donating their organs. Furthermore, 113 (55%) participants would consider receiving an organ from an HIV patient, 37 (18%) would not consider it, and 56 (27%) were unsure. Ninety-eight participants (42%) reported that they would consider both donating and receiving an organ. Multinomial logistic regression analysis found that significantly more Black African than Caucasian participants were unsure about organ donation (p = 0.011, OR = 3.887). Participants with longer duration of infection were significantly less likely to consider receiving an organ from an HIV patient (p = 0.036, OR = 1.297). Overall, the study findings indicated that the majority of participants were in favour of organ transplant between HIV patients. Use of HIV-infected donors could potentially reduce current organ waiting list among HIV patients.

Abstract
UNLABELLED High rates of sexually transmitted infection and reinfection with hepatitis C virus (HCV) have recently been reported in human immunodeficiency virus (HIV)-infected men who have sex with men and reinfection has also been described in monoinfected injecting drug users. The diagnosis of reinfection has traditionally been based on direct Sanger sequencing of samples pre- and posttreatment, but not on more sensitive deep sequencing techniques. We studied viral quasispecies dynamics in patients who failed standard of care therapy in a high-risk HIV-infected cohort of patients with early HCV infection to determine whether treatment failure was associated with reinfection or recrudescence of preexisting infection. Paired sequences (pre- and posttreatment) were analyzed. The HCV E2 hypervariable region-1 was amplified using nested reverse-transcription polymerase chain reaction (RT-PCR) with indexed genotype-specific primers and the same products were sequenced using both Sanger and 454 pyrosequencing approaches. Of 99 HIV-infected patients with acute HCV treated with 24-48 weeks of pegylated interferon alpha and ribavirin, 15 failed to achieve a sustained virological response (six relapsed, six had a null response, and three had a partial response). Using direct sequencing, 10/15 patients (66%) had evidence of a previously undetected strain posttreatment; in many studies, this is interpreted as reinfection. However, pyrosequencing revealed that 15/15 (100%) of patients had evidence of persisting infection; 6/15 (40%) patients had evidence of a previously undetected variant present in the posttreatment sample in addition to a variant that was detected at baseline. This could represent superinfection or a limitation of the sensitivity of pyrosequencing. CONCLUSION In this high-risk group, the emergence of new viral strains following treatment failure is most commonly associated with emerging dominance of preexisting minority variants rather than reinfection. Superinfection may occur in this cohort but reinfection is overestimated by Sanger sequencing.

Abstract
Hepatitis B and human immunodeficiency virus (HBV and HIV) infection share transmission patterns and risk factors, which explains high prevalence of chronic HBV infection in HIV infected patients. The natural course of HBV disease is altered by the HIV infection with less chance to clear acute HBV infection, faster progression to cirrhosis and higher risk of liver-related death in HIV-HBV co-infected patients than in HBV mono-infected ones. HIV infected patients with chronic hepatitis B should be counseled for liver damage and surveillance of chronic hepatitis B should be performed to screen early hepatocellular carcinoma. Noninvasive tools are now available to evaluate liver fibrosis. Isolated hepatitis B core antibodies (anti-HBc) are a good predictive marker of occult HBV infection. Still the prevalence and significance of occult HBV infection is controversial, but its screening may be important in the management of antiretroviral therapy. Vaccination against HBV infection is recommended in non-immune HIV patients. The optimal treatment for almost all HIV-HBV co-infected patients should contain tenofovir plus lamivudine or emtricitabine and treatment should not be stopped to avoid HBV reactivation. Long term tenofovir therapy may lead to significant decline in hepatitis B surface Antigen. The emergence of resistant HBV strains may compromise the HBV therapy and vaccine therapy.

Abstract
BACKGROUND Hepatitis B vaccine has been recommended for use in people living with HIV (PLHIV) mostly because of the similarities in routes of infection and their prevalence in the same geographic areas. PLHIV may not develop sero-protection after receiving standard hepatitis B vaccine due to their compromised immune status. OBJECTIVES To evaluate the efficacy of hepatitis B virus vaccine in PLHIV compared to placebo or no vaccine. SEARCH METHODS We searched 6 English language databases in July 2012, and updated the search in June 2013 and August 2014. We searched the grey literature, conference proceedings, specialised web sites, and contacted experts in the field. SELECTION CRITERIA Randomised controlled trials of hepatitis B vaccine compared to placebo or no vaccine, evaluating relevant outcomes of efficacy and safety. DATA COLLECTION AND ANALYSIS Two review authors independently sought and extracted data on study design, participants, hepatitis B infection, hepatitis B related morbidity and mortality, anti-HBs immunogenicity and adverse effects related to vaccines from published articles or through correspondence with authors. Data were analysed qualitatively. MAIN RESULTS One double-blind randomised controlled trial with 26 participants who were on antiretroviral therapy (ART), comparing hepatitis B vaccine to placebo conducted in Spain met our eligibility criteria and was included in this review. The study ran for three years and participants were followed up on a monthly basis. The study reported adequate humoral response to vaccine at 12 months and no local or systematic side effects in both intervention and control groups. This humoral response was lost when the participants stopped taking ART. The sample size of the study was small and the study was conducted in a high income setting unlike the areas of highest burden of hepatitis B and HIV co-infections. AUTHORS' CONCLUSIONS The evidence from this study is insufficient to support any recommendations regarding the use of hepatitis B vaccine in PLHIV. Neither does this evidence demonstrate that hepatitis B vaccine is unsafe in PLHIV. Further randomised controlled trials in high prevalence areas are required to generate evidence on the long term efficacy and safety of hepatitis B vaccine in PLHIV with and without ART. Different regimens and routes of administration should also be explored.

Abstract
BACKGROUND Current guidelines recommend that interferon-based treatment of hepatitis C (HCV) genotype 2 or 3 in those with HIV coinfection should be for 48 weeks, especially if HCV PCR remains positive after 4 weeks of treatment. AIM To examine a single-center experience using response-guided therapy (RGT) using pegylated interferon (PegIFN) and weight-based ribavirin (RBV) for treating HCV genotype 2 or 3 in those with HIV coinfection. METHODS Electronic medical records were used to identify patients with HCV genotype 2 or 3 HIV coinfection seen at the Toronto General Hospital Immunodeficiency Clinic from February 2003 to December 2012. HCV PCR was tested after every 4 weeks of treatment until it was negative (<50 IU/mL). RGT protocol was as follows: Those with HCV PCR first negative after 4 weeks (VR4) were treated 24 weeks; first negative after 8 weeks (VR8) treated 36 weeks and VR12 treated 48 weeks. RESULT Database search identified 35 individuals with HCV genotype 2 or 3. Twelve were excluded. Total 23 patients completed the treatment and were included for data analysis. Eleven of 23 (48 %) achieved VR4 and eleven of 23 (48 %) achieved VR8. Only one individual had detectable viremia to week 12 and required 48 weeks of treatment. The majority (96 %) were successfully treated with <48 weeks of PegIFN-RBV therapy. One hundred percent achieved SVR with a response-guided HCV therapy. CONCLUSION The use of response-guided therapy allows therapy to be shortened in the majority of individuals. HCV PCR testing should be performed every 4 weeks during the first 12 weeks of therapy until HCV PCR is negative.

Abstract
Human immunodeficiency virus (HIV), Hepatitis B (HBV) and Hepatitis C (HCV) are blood-borne viruses with potentially shared routes of transmission. In high-income settings, the impact of antiretroviral therapy (ART) on survival has unmasked chronic liver disease from viral hepatitis B or hepatitis C as a leading cause of morbidity and mortality in individuals with HIV infection. It is now feared that progressive liver disease may threaten the success of ART programmes in developing countries, where HCV or HBV testing and monitoring are not yet systematic among HIV-infected patients and ART use is generally blind to these co-infections. We set out to review recent data from Sub-Saharan Africa, in order to build a detailed and up-to-date picture of the epidemiology and emerging impact of HBV and HCV coinfection in countries at the heart of the HIV pandemic. There is a preponderance of HIV/HBV coinfection compared to HIV/HCV in this region, and significant caveats exist regarding the accuracy of published HCV seroprevalence surveys. Morbidity and mortality of coinfection is significant, and may be further enhanced in African populations due to the influence of host, viral and environmental factors. Careful scrutiny of the coinfection problem is vital to inform an approach to directing resources, planning public health initiatives, providing clinical care, and guiding future research.

Abstract
HCV and HIV co-infection is associated with accelerated hepatic fibrosis progression and higher rates of liver decompensation and death compared to HCV monoinfection, and liver disease is a leading cause of non-AIDS-related mortality among HIV-infected patients. New insights have revealed multiple mechanisms by which HCV and HIV lead to accelerated disease progression, specifically that HIV infection increases HCV replication, augments HCV-induced hepatic inflammation, increases hepatocyte apoptosis, increases microbial translocation from the gut and leads to an impairment of HCV-specific immune responses. Treatment of HIV with antiretroviral therapy and treatment of HCV have independently been shown to delay the progression of fibrosis and reduce complications from end-stage liver disease among co-infected patients. However, rates of sustained virologic response with PEG-IFN and ribavirin have been significantly inferior among co-infected patients compared with HCV-monoinfected patients, and treatment uptake has remained low given the limited efficacy and tolerability of current HCV regimens. With multiple direct-acting antiviral agents in development to treat HCV, a unique opportunity exists to redefine the treatment paradigm for co-infected patients, which incorporates data on fibrosis stage as well as potential drug interactions with antiretroviral therapy.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) coinfection accelerates the rate of liver disease outcomes in individuals chronically infected with hepatitis C virus (HCV). It remains unclear to what degree combination antiretroviral therapy (ART) protects against HCV-associated liver failure. METHODS We evaluated 10 090 HIV/HCV-coinfected males from the Veterans Aging Cohort Study Virtual Cohort, who had not initiated ART at entry, for incident hepatic decompensation between 1996 and 2010. We defined ART initiation as the first pharmacy fill date of a qualifying ART regimen of ≥3 drugs from ≥2 classes. Hepatic decompensation was defined as the first occurrence of 1 hospital discharge diagnosis or 2 outpatient diagnoses for ascites, spontaneous bacterial peritonitis, or esophageal variceal hemorrhage. To account for potential confounding by indication, marginal structural models were used to estimate hazard ratios (HRs) of hepatic decompensation, comparing initiation of ART to noninitiation. RESULTS We observed 645 hepatic decompensation events in 46 444 person-years of follow-up (incidence rate, 1.4/100 person-years). Coinfected patients who initiated ART had a significantly reduced rate of hepatic decompensation relative to noninitiators (HR = 0.72; 95% confidence interval [CI], .54-.94). When we removed individuals with HIV RNA ≤400 copies/mL at baseline from the analysis (assuming that they may have received undocumented ART at entry), the hazard ratio became more pronounced (HR = 0.59; 95% CI, .43-.82). CONCLUSIONS Initiation of ART significantly reduced the rate of hepatic decompensation by 28%-41% on average. These results suggest that ART should be administered to HIV/HCV-coinfected patients to lower the risk of end-stage liver disease.

Abstract
Small cohort studies from countries where both HIV and HBV are endemic demonstrate prevalence rates of chronic hepatitis B in HIV-infected children of between 1 and 49%. While data on coinfected children are limited, results from studies in adults with HIV/HBV coinfection raise the concern that coinfected children may be at a higher risk of liver disease, hepatic fibrosis and cirrhosis. With the scale-up of combination antiretroviral therapy worldwide, of which lamivudine is included in most first-line regimens, coinfected children treated with lamivudine risk development of HBV resistance mutations. This article summarizes the current literature relevant to HIV/HBV coinfection in children, the options for treatment and highlights priorities for future research.

Abstract
The immunosuppressed state may arise due to medical illness or drug therapy, which can result in a diverse array of liver derangements. This article discusses the commonly-encountered immunosuppressed conditions and the associated specific liver diseases. Due to the frequency of blood-borne viral disease globally, viral hepatitis (hepatitis B and C) during chemotherapy, transplantation and the increasingly utilised biological therapies for autoimmune disorders is discussed. An overview of human immunodeficiency virus co-infection with hepatitis B and C is provided. This article aims to highlight the variety of liver diseases which can occur in clinically relevant, particularly iatrogenic, immunosuppressed conditions, and summarise learning and practice points for clinicians. Recognition and prevention of viral liver disease is crucial and early involvement of experts prior to administration of immunosuppressive therapy is advised.

Abstract
BACKGROUND Hepatitis B coinfection is common in HIV-positive individuals and as antiretroviral therapy has made death due to AIDS less common, hepatitis has become increasingly important. Several drugs are available to treat hepatitis B. The most potent and the one with the lowest risk of resistance appears to be tenofovir (TDF). However there are several questions that remain unanswered regarding the use of TDF, including the proportion of patients that achieves suppression of HBV viral load and over what time, whether suppression is durable and whether prior treatment with other HBV-active drugs such as lamivudine, compromises the efficacy of TDF due to possible selection of resistant HBV strains. METHODS A systematic review and meta-analysis following PRISMA guidelines and using multilevel mixed effects logistic regression, stratified by prior and/or concomitant use of lamivudine and/or emtricitabine. RESULTS Data was available from 23 studies including 550 HBV/HIV coinfected patients treated with TDF. Follow up was for up to seven years but to ensure sufficient power the data analyses were limited to three years. The overall proportion achieving suppression of HBV replication was 57.4%, 79.0% and 85.6% at one, two and three years, respectively. No effect of prior or concomitant 3TC/FTC was shown. Virological rebound on TDF treatment was rare. INTERPRETATION TDF suppresses HBV to undetectable levels in the majority of HBV/HIV coinfected patients with the proportion fully suppressed continuing to increase during continuous treatment. Prior treatment with 3TC/FTC does not compromise efficacy of TDF treatment. The use of combination treatment with 3TC/FTC offers no significant benefit over TDF alone.

Abstract
BACKGROUND The purpose of this study was to update the epidemiological data on the prevalence of coinfection with hepatitis C virus (HCV) and HIV, and to identify whether specific clinical and epidemiological factors influenced the response of HIV-positive adults to highly active antiretroviral therapy (HAART). METHODS This retrospective observational cohort study of 238 HIV-infected patients evaluated the effect of different epidemiological and clinical parameters (including HCV coinfection) on therapy response among HIV-infected adults initiating HAART. Multiple logistic regression models were used to identify factors associated with therapy response and estimated risk coefficients. RESULTS Seroprevalence of HCV infection in this population was 26% (62/238). We did not observe a significant association between immunological or virological response relating to patient gender or HAART regimen. However, this analysis showed that HCV serological status, age at HIV diagnosis, duration of treatment and WHO clinical stage of AIDS (<200 CD4 cells/ml independently of viral load either < or > to 100,000 copies/ml), were significantly associated with immunological and virological responses to HAART. CONCLUSIONS These results show further evidence that hepatitis C serostatus is associated with a reduced response to HAART.

Abstract
OBJECTIVE The aim of this study was to identify and describe patients with detectable hepatitis B virus (HBV) DNA in the presence of undetectable HIV RNA after 48 weeks of tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) or lamivudine (3TC) treatment. DESIGN Case-control study. Cases or delayed responders were defined as detectable HBV DNA (>20 IU/ml) with undetectable HIV RNA (<40 c/ml) after 48 weeks TDF/3(F)TC combination therapy. Controls or virological responders were defined as both undetectable HIV and HBV after 48 weeks TDF/3(F)TC therapy. RESULTS Twenty-three cases were identified and matched to 24 controls. 87% cases and 46% controls were eAg-positive (P=0.005). Nine of 23 (39%) cases and seven of 24 (29%) controls had 3TC monotherapy prior to TDF. Similar proportions had 3TC/FTC resistance pre-TDF (30% cases, 24% controls). The cases had significantly higher baseline HBV DNA pre-3TC (median 1.2×10(8) vs. 3.1×10(6) IU/ml; P=0.009) and pre-TDF (1.1×10(8) vs. 2.6×10(4) IU/ml; P=0.012). Sixteen of 23 cases eventually achieved undetectable HBV DNA after 42.2 (27.2, 54.9) months. Six of 23 still have detectable HBV DNA after 46.2 (28.2, 65.6) months. Only one delayed responder patient developed a new 3(F)TC mutation and they received intensification with entecavir and achieved undetectable HBV DNA. No patient developed TDF resistance. CONCLUSION We report the largest series of HIV/HBV co-infected patients failing to achieve undetectable HBV after 48 weeks TDF/3(F)TC despite undetectable HIV viraemia. This outcome was associated with positive eAg and higher baseline HBV DNA. Our data suggest that clinicians should not intensify therapy with entecavir unless there is evidence of new 3TC/FTC mutations as the majority of patients go on to suppress HBV. TDF resistance was not seen.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection is common in individuals infected with human immunodeficiency virus, especially in men who have sex with men (MSM). Almost all currently used regimens of antiretroviral therapy (ART) contain lamivudine (LAM) or tenofovir disoproxil fumarate (TDF), both of which have significant anti-HBV activity. However, the prophylactic effect of ART on HBV infection has not been assessed previously. METHODS Non-HBV-vaccinated HIV-infected MSM were serologically evaluated for HBV infection using stocked serum samples. Cases negative for HBV surface antigen (HBsAg), antibody to HBsAg (anti-HBs), and antibody to HBV core antigen (anti-HBc) in first serum samples were serologically followed until last available stocked samples. HBV genotype and LAM-resistant mutation (rtM204V/I) were analyzed in cases that became HBsAg-positive. RESULTS The first stocked samples were negative for all analyzed HBV serological markers in 354 of 1434 evaluated patients. The analysis of their last samples indicated HBV incident infection in 43 of them during the follow-up period. The rate of incident infections was lower during LAM- or TDF-containing ART (0.669 incident infections in 100 person-years) than during no ART period (6.726 incident infections in 100 person-years) and other ART (5.263 incident infections in 100 person-years) (P < .001). Genotype A was most prevalent (76.5%), and LAM-resistant HBV was more frequent in incident infections during LAM-containing ART (50.0%) than in those during no ART and other ART (7.1%) (P = .029). CONCLUSIONS LAM- and TDF-containing ART regimens seem to provide prophylaxis against HBV infection, although drug-resistant strains seem to evade these effects.

Abstract
Background Hepatitis B virus (HBV) infection is an increasingly important cause of morbidity and mortality in HIV-infected adults. This study aimed to determine the prevalence and incidence of HBV in the UK CHIC Study, a multicentre observational cohort. Methods and Findings 12 HIV treatment centres were included. Of 37,331 patients, 27,450 had at least one test (HBsAg, anti-HBs or anti-HBc) result post-1996 available. 16,043 were white, 8,130 black and 3,277 other ethnicity. Route of exposure was homosexual sex 15,223 males, heterosexual sex 3,258 males and 5,384 females, injecting drug use 862 and other 2,723. The main outcome measures used were the cumulative prevalence and the incidence of HBV coinfection. HBV susceptible patients were followed up until HBsAg and/or anti-HBc seroconversion incident infection, evidence of vaccination or last visit. Poisson regression was used to determine associated factors. 25,973 had at least one HBsAg test result. Participants with HBsAg results were typically MSM (57%) and white (59%) (similar to the cohort as a whole). The cumulative prevalence of detectable HBsAg was 6.9% (6.6 to 7.2%). Among the 3,379 initially HBV-susceptible patients, the incidence of HBV infection was 1.7 (1.5 to 1.9)/100 person-years. Factors associated with incident infection were older age and IDU. The main limitation of the study was that 30% of participants did not have any HBsAg results available. However baseline characteristics of those with results did not differ from those of the whole cohort. Efforts are on-going to improve data collection. Conclusions The prevalence of HBV in UK CHIC is in line with estimates from other studies and low by international standards. Incident infection continued to occur even after entry to the cohort, emphasising the need to ensure early vaccination.

Abstract
Co-infection with HIV and hepatitis B virus (HBV) has serious long-term consequences. We describe a case of an HIV-infected heterosexual black African man with a delayed diagnosis of HBV infection. Baseline HBV screening was performed using a sequential testing algorithm starting with a total core antibody (anti-HBc) test, which was negative. He had no evidence of immunity against HBV and subsequently received three unsuccessful courses of HBV vaccination. He had mild but persistent elevation of liver enzymes over a five-year period despite maintaining full suppression of HIV replication on efavirenz, lamivudine and zidovudine; the latter was changed to abacavir due to lipoatrophy. Further testing revealed e-antibody positive chronic HBV infection with undetectable anti-HBc reactivity. High-grade HBV viraemia associated with L180M and M240V drug-resistance mutations was confirmed. He was subsequently switched to a tenofovir-based regimen, which achieved HBV suppression. Adopting effective HBV screening strategies in HIV-infected patients is recommended.

Abstract
BACKGROUND Several studies reported an association between immunodeficiency and non-AIDS-defining diseases. We investigated whether nonstructured treatment interruptions and episodes of viremia during suppressive combination antiretroviral therapy were independently associated with non-AIDS diseases. METHODS Six thousand four hundred forty patients with viral suppression (<50 copies/mL) within 48 weeks of starting combination antiretroviral therapy were selected from the Dutch ATHENA cohort. In proportional hazards models, associations between treatment interruptions, viral suppression, low-level (50-400 copies/mL), and high-level viremia (>400), and serious non-AIDS diseases (cardiovascular disease, chronic renal failure, liver fibrosis/cirrhosis) were investigated by including time-updated cumulative exposure to either viremia and interruptions or HIV RNA >400 copies per milliliter. RESULTS During 24,603 person-years, of which 88.5% occurred during viral suppression, 102 patients developed cardiovascular disease, 54 chronic renal failure, and 70 liver fibrosis/cirrhosis. Overall incidence of non-AIDS diseases ranged from 1.41 (95% confidence interval: 0.73 to 2.46) per 100 person-years for CD4 counts <200 to 0.71 (0.49 to 1.00) for CD4 ≥500 cells per cubic millimeter. Compared with viral suppression, high-level viremia was associated only with cardiovascular disease (relative hazard: 1.37, 1.04 to 1.81 per year longer), whereas interruptions and low-level viremia were not associated with non-AIDS diseases. Relative hazards for cumulative exposure to RNA >400 versus ≤400 copies per milliliter were 1.32 (1.01 to 1.73) for cardiovascular disease, 1.13 (0.66 to 1.92) for renal failure, and 0.86 (0.51 to 1.44) for fibrosis/cirrhosis. CONCLUSIONS Lower CD4 counts are associated with increased risk of non-AIDS diseases, whereas high-level viremia seems to be independently associated with cardiovascular disease. However, the power to detect associations with viremia or interruptions may have been limited as most events occurred during viral suppression.

Abstract
OBJECTIVES This study aimed to determine the prevalence of hepatitis B virus (HBV) coinfection and HBV seropositivity in perinatally HIV-infected adolescents. A secondary objective was to describe the clinical characteristics of adolescents with chronic HBV/HIV coinfection. MATERIALS AND METHODS Multicenter cross-sectional study of perinatally HIV-infected adolescents aged 12-25 years. HBV surface antigen, surface antibody (anti-HBs) and core antibody (anti-HBc) were measured. Coinfection was defined as having persistently positive HBV surface antigen. Seroprotective antibody from immunization was defined as having anti-HBs ≥10 mIU/mL with negative anti-HBc. HBV DNA quantitation and rtM204V/I mutation analysis (lamivudine resistance-associated mutation) were performed in adolescents with chronic HBV infection. RESULTS From November 2010 to March 2011, 521 patients were enrolled. Mean (SD) of CD4 lymphocyte count was 685 (324) cells/μL. The prevalence of HBV/HIV coinfection was 3.3% (95% confidence interval: 1.9-5.2%). Protective antibody against HBV was found in 18% of population, and this was significantly higher among adolescents who received than those who did not receive HBV revaccination after receiving antiretroviral therapy (93% versus 6%, P < 0.01). Among adolescents with chronic HBV infection, 88% have received lamivudine; however, 69% have HBV DNA >10 copies/mL and 75% had the rtM204V/I mutation. CONCLUSIONS The prevalence of HBV coinfection in HIV-infected Thai adolescents was 3.3%. Most HIV-infected adolescents had no HBV protective antibody; therefore, revaccination with HBV vaccine is encouraged. The high prevalence of HBV-lamivudine resistance underscores the importance of HBV screening prior to antiretroviral therapy initiation to guide the selection of optimal regimen for coinfected children.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection has a growing impact on morbidity and mortality in patients infected with human immunodeficiency virus (HIV). We assessed trends in HCV incidence in the different HIV transmission groups in the Swiss HIV Cohort Study (SHCS). METHODS HCV infection incidence was assessed from 1998, when routine serial HCV screening was introduced in the SHCS, until 2011. All HCV-seronegative patients with at least 1 follow-up serology were included. Incidence rates (IRs) of HCV infections were compared between men who have sex with men (MSM), injection drug users (IDU), and heterosexuals (HET). RESULTS HCV incidence was assessed in 3333 MSM, 123 IDU, and 3078 HET with a negative HCV serology at baseline. Over 23 707 person-years (py) for MSM, 733 py for IDU, and 20 752 py for HET, 101 (3%), 41 (33%), and 25 (1%) of patients seroconverted, respectively. The IR of HCV infections in MSM increased from 0.23 (95% credible interval [CrI], .08-.54) per 100 py in 1998 to 4.09 (95% CrI, 2.57-6.18) in 2011. The IR decreased in IDU and remained <1 per 100 py in HET. In MSM, history of inconsistent condom use (adjusted hazard ratio [HR], 2.09; 95% CI, 1.33-3.29) and past syphilis (adjusted HR, 2.11; 95% confidence interval [CI], 1.39-3.20) predicted HCV seroconversion. CONCLUSIONS In the SHCS, HCV infection incidence decreased in IDU, remained stable in HET, and increased 18-fold in MSM in the last 13 years. These observations underscore the need for improved HCV surveillance and prevention among HIV-infected MSM.

Abstract
With effective treatment of HIV-1, hepatitis C virus (HCV) has become increasingly recognized as a major cause of morbidity and mortality in this population. Rapid progression of liver disease and cirrhosis has been documented in HIV/HCV co-infected individuals, particularly with lower CD4-counts (< 200/μL). Therefore, HCV treatment has become a priority for many clinicians, despite the presence of many. An important issue among HIV/HCV co-infected patients is the selection of antiretroviral therapy (ART) during treatment with pegylated interferon, ribavirin (RBV), plus new HCV protease inhibitors. Extensive drug-drug interactions (DDI) and overlapping drug-associated adverse events can impact the outcome of HCV therapy. In this review, we focus on the important data and studies regarding optimizing antiretroviral regimens before starting HCV treatment in HIV/HCV co-infected patients to increase the chance of sustained virologic response (SVR).

Abstract
An electronic search was performed of the electronic patient record (EPR) system to identify whether each of 13 key interventions recommended by the British HIV Association (BHIVA) had been performed for all eligible patients attending in 2009 and 2010 at one of our HIV clinics: 345 and 358 eligible HIV-positive patients were identified in 2009 and 2010, respectively. The success rates for having completed each intervention in 2009 and 2010, respectively, were all better for 2010 and none was <94%. These improved results in 2010 over those of 2009 could be attributed to the clinicians’ improved experience in using the checklist and the facility of EPR to provide flagged reminders.

Abstract
With the rapid scale up of antiretroviral therapy, there is a dramatic decline in HIV related morbidity and mortality in both developed and developing countries. Several new safe antiretroviral, and newer class of drugs and monitoring assays are developed recently. As a result the treatment guideline for the management of HIV disease continue to change. This review focuses on evolving science on Indian policy - antiretroviral therapy initiation, which drugs to start with, when to change the initial regimen and what to change.

Abstract
PURPOSE OF REVIEW Liver disease is an important cause of morbidity and mortality in the era of combination antiretroviral therapy in HIV/hepatitis C virus (HCV) co-infected patients. This review highlights the role of pegylated interferon-alpha (peg-IFN) and ribavirin (RBV) therapy and examines factors associated with response and strategies to maximize responses. RECENT FINDINGS HCV viral clearance is lower in HIV co-infected patients than in HCV mono-infected patients. However, in patients who attain sustained response there is clinical benefit in terms of liver disease associated morbidity and mortality and treatment is costeffective. Predictors of response appear similar, although there are a number of modifiable patient-associated and HIV-associated factors that could be addressed. Moreover, the use of weight-based RBV and treatment length guided by early viral responses improve response rate. Avoidance of drug-drug interactions and use of haematopoietic growth factors reduce adverse events and dose reductions and ultimately increase response rates. Very early prediction of treatment futility is promising. Induction dosing strategies have not yielded positive results, though twice weekly peg-IFN-alpha-2a induction therapy merits further investigation. SUMMARY Peg-IFN/RBV therapy plays an important role in the management of HCV in HIV-infected patients. Efforts to maximize response to current therapy need to continue while we await new therapies.

Abstract
OBJECTIVE To examine HIV and hepatitis B virus (HBV)-related outcomes in HIV/HBV-coinfected participants in the PHIDISA II study by use of HBV-active vs. non-HBV-active antiretroviral therapy (ART). DESIGN AND METHODS PHIDISA II was a randomized study of ART therapy in HIV-infected adults employing zidovudine along with didanosine, or lamivudine along with stavudine in a factorial 2x2 design. HIV/HBV-coinfected participants by randomization received HBV-active or non-HBV-active ART. The following outcomes of interest were examined: immunological recovery and HIV RNA suppression; hepatic flare; HBV DNA suppression; and mortality. RESULTS HIV/HBV coinfection was present in 106 of 1771 (6%) of participants. Participants with HIV/HBV coinfection were more likely to be men, and have higher baseline alanine aminotransferase, lower albumin, and lower platelets than those with HIV monoinfection. Median CD4 cell gain and HIV RNA suppression was similar across all groups. Hepatic flare was observed in 9.4% of coinfected and 0.02% monoinfected participants. HBV DNA suppression (<55 IU/ml) at week 48 was observed in only 33% of those on lamivudine vs. 13% in those on no HBV-active drugs (P = 0.13). Mortality over follow-up was significantly greater in coinfected (17%) than monoinfected (11%) participants (P = 0.04). CONCLUSION In summary, the use of lamivudine-containing ART in HIV/HBV participants in PHIDISA II resulted in little additional benefit over that of ART itself and failed to impact on the greater mortality in this group. These data provide strong support for recent guidelines advocating the use of tenofovir in all HIV-HBV-coinfected individuals initiating ART.

Abstract
BACKGROUND Combination emtricitabine (FTC) or lamivudine (LAM) with tenofovir disoproxil (TDF) is the recommended first-line regime for treatment in chronic hepatitis B virus (HBV)/HIV co-infection. However, in those failing to suppress, few data exist regarding further management. In HBV/HIV co-infection, there are no published data describing outcomes when entecavir (ETV) is then added to TDF-based regimes in patients no longer suppressing their HBV. We report the first series of patients using ETV with truvada-based HAART in HBV/HIV co-infected patients with previous HBV therapy failure, including inadequate suppression. METHODS A prospective observational study. RESULTS Thirteen HIV/HBV co-infected patients (all male, hepatitis B e antigen positive and hepatitis B e antibody negative) were commenced on ETV in addition to background truvada. All patients were previously exposed to LAM or FTC and TDF (median 53 months, range 6−123). Seven patients had LAM monotherapy prior to TDF/LAM or FTC combination; the remaining six patients were exposed to FTC or LAM and TDF combination. Median time of follow-up was 74 weeks (range 16−159) and median HBV decline was 2.53 log(10) IU/ml (range 1.28−7.36). Thirty-eight percent of patients achieved undetectable HBV DNA level by the end of the study and eight of 13 (62%) achieved normal alanine aminotransferase (ALT) levels with median reduction −28 U/l (range −152 to 37). TDF was stopped in one patient because of renal toxicity. ETV was well tolerated with no change of estimated glomerular filtration rate during the study. CONCLUSION Entecavir can be considered in addition to TDF/FTC in HBV/HIV co-infected treatment-experienced patients failing to fully suppress their HBV viral load.

Abstract
Chronic hepatitis C is frequent and aggressive among HIV-positive patients; evaluation for anti-hepatitis C virus (HCV)-specific therapy is mandatory, but it has many limitations, due to efficacy, tolerability but also applicability. The objective of our retrospective analysis was to evaluate the eligibility and feasibility of anti-HCV therapy in HIV/HCV-coinfected patients followed at the II Department of Infectious Diseases, L. Sacco Hospital, Milan, Italy, from 2000 to March 2010. In our database, 545 HIV/HCV-coinfected patients were present, representing 40% of our whole HIV population, and 421 included in the analysis. One hundred twenty-four patients were excluded because of loss to follow-up (81) or deceased (43). Forty-eight patients spontaneously cleared HCV during follow-up (11%). Ninety-nine patients received anti-HCV therapy (26%), while the majority was excluded for several reasons (mainly concomitant diseases and low CD4(+) cell count). Globally, we found that in at least one third of untreated patients modifiable barriers to treatment were present. The access to therapy was significantly associated with the absence of history of intravenous drug use (p=0.01), a higher CD4(+) cells count at nadir (p=0.01), the presence of more than 6 HAART regimens (p=0.04), higher alanine aminotransferase (ALT) levels (p<0.0001), HCV genotype 2 or 3 (p=0.005). In a multivariate analysis, the same factors remained significantly associated with anti-HCV therapy. In conclusion, the feasibility of anti-HCV therapy in HIV/HCV-coinfected patients, in our highly specialized center, is approximately 26%. Relative contraindications, such as substance abuses, mild and controlled concomitant conditions, and low compliance are common and modifiable in order to reconsider patients as suitable for therapy.

Abstract
Introduction of effective combined antiretroviral therapy has made HIV infection a chronic illness. Substantial reductions in the number of AIDS-related deaths have been accompanied by an increase in liver-related morbidity and mortality due to co-infection with chronic hepatitis B and C viruses. Increases in non-alcoholic fatty liver disease and drug-induced hepatotoxicity, together with development of hepatocellular carcinoma, also potentiate the burden of liver disease in individuals with HIV infection. We provide an overview of the key causes, disease mechanisms of pathogenesis, and recommendations for treatment options including the evolving role of liver transplantation.

Abstract
The aim of this work was to survey current service provision and adherence to the British HIV Association (BHIVA) guidelines for the management of HIV and hepatitis B/C co-infected patients in the UK. Sites were invited to complete a survey of local care arrangements for co-infected patients. A case-note audit of all co-infected attendees during a six-month period in 2009 was performed. Data including demographics, clinical parameters, hepatitis disease status, antiretroviral and hepatitis B/C therapy were collected. Using BHIVA guidelines as audit standards, the proportion of sites and subjects meeting each standard was calculated. One-hundred and forty sites (75%) responded and data from 973 eligible co-infected patients were submitted. Approximately a third of sites reported not re-checking hepatitis serology or vaccination titres annually. Of all co-infected patients, 122 (13%) were neither vaccinated nor immune to hepatitis A and 26 (5%) of patients with hepatitis C were neither vaccinated nor naturally immune to hepatitis B. Of HBsAg-positive subjects, 25 (6%) were receiving lamivudine as the sole drug with antihepatitis B activity. In the UK, the management of HIV and hepatitis B/C co-infection remains highly variable. Optimizing the care of this high-risk patient group is a priority.
