RESUMO

In the United States, approximately 25% of people with HIV (PWH) are co-infected with hepatitis C (HCV). Since 2014, highly effective and well-tolerated direct-acting antivirals (DAAs) have revolutionized HCV treatment. Uptake of DAAs by people with HIV/HCV co-infection has improved but remains suboptimal due to system, provider, and patient-level barriers. To explore patient-level issues by better understanding their attitudes towards DAA treatment, we conducted qualitative interviews with 21 persons with HIV/HCV co-infection who did not consent to DAA treatment or delayed treatment for at least 1 year after diagnosis. We found PWH perceived DAA treatment barriers and facilitators on multiple levels of the social-ecological environment: the individual (HCV disease and treatment literacy), interpersonal (peer influence), institutional (media and healthcare provider relationship), and structural levels (treatment cost and adherence support). Recommendations to improve DAA treatment uptake include HCV-treatment adherence support, HCV disease and treatment literacy training (particularly for substance use and DAA treatment interactions), and encouraging PWH who have successfully completed DAA treatment to speak with their peers.

RESUMO

BACKGROUND: Depression is common in the human immunodeficiency virus (HIV)-hepatitis C virus (HCV) co-infected population. Demographic, behavioural, and clinical data collected in research settings may be of help in identifying those at risk for clinical depression. We aimed to predict the presence of depressive symptoms indicative of a risk of depression and identify important classification predictors using supervised machine learning. METHODS: We used data from the Canadian Co-infection Cohort, a multicentre prospective cohort, and its associated sub-study on Food Security (FS). The Center for Epidemiologic Studies Depression Scale-10 (CES-D-10) was administered in the FS sub-study; participants were classified as being at risk for clinical depression if scores ≥ 10. We developed two random forest algorithms using the training data (80%) and tenfold cross validation to predict the CES-D-10 classes-1. Full algorithm with all candidate predictors (137 predictors) and 2. Reduced algorithm using a subset of predictors based on expert opinion (46 predictors). We evaluated the algorithm performances in the testing data using area under the receiver operating characteristic curves (AUC) and generated predictor importance plots. RESULTS: We included 1,934 FS sub-study visits from 717 participants who were predominantly male (73%), white (76%), unemployed (73%), and high school educated (52%). At the first visit, median age was 49 years (IQR:43-54) and 53% reported presence of depressive symptoms with CES-D-10 scores ≥ 10. The full algorithm had an AUC of 0.82 (95% CI:0.78-0.86) and the reduced algorithm of 0.76 (95% CI:0.71-0.81). Employment, HIV clinical stage, revenue source, body mass index, and education were the five most important predictors. CONCLUSION: We developed a prediction algorithm that could be instrumental in identifying individuals at risk for depression in the HIV-HCV co-infected population in research settings. Development of such machine learning algorithms using research data with rich predictor information can be useful for retrospective analyses of unanswered questions regarding impact of depressive symptoms on clinical and patient-centred outcomes among vulnerable populations.

RESUMO

Alcohol use contributes to the progression of liver disease in HIV-HCV co-infected persons, but alcohol interventions have never addressed low levels of alcohol use in this population. We enrolled 110 persons consuming at least 4 alcoholic drinks weekly in a clinical trial comparing two active 18-month long interventions, delivered every 3 months by phone, brief advice about drinking versus a motivational intervention. Final assessment was at 24 months. MI had larger reductions in alcohol use days than the BA arm at all follow-up assessments. The treatment by time effect was not significant for days of drinking (p = 0.470), mean drinks per day (p = 0.155), or for the continuous FIB-4 index (p = 0.175). Drinking declined in both conditions from baseline, but given the small sample, we do not have sufficient data to make any conclusion that one treatment is superior to the other.Trial Registry Trial registered at clinicaltrials.gov; Clinical Trial NCT02316184.

RESUMO

BACKGROUND: Acute hepatitis C virus (AHC) infection is increasingly common among HIV+ men who have sex with men (MSM). Until 2017, the guidelines recommended therapy with pegylated-interferon plus ribavirin with a mild sustained virological response (SVR). This prompted many patients to reject that treatment, at that time, waiting to be treated with better and safer options with new Direct-Acting-Antivirals (DAA). OBJECTIVES: Assess the efficacy and safety of Elbasvir/Grazoprevir to treat recent chronic hepatitis C infection, genotype 1 or 4, in HIV+ MSM patients. METHODS: Prospective, open-labeled, two center, pilot study. SVR is analyzed for treatment with Elbasvir/Grazoprevir (8 weeks in GT1b or 12 in GT1a or GT4) in patients with a recent chronic HCV infection, defined as HCV infection lasting less than 4 years and mild liver fibrosis (liver stiffness <8kPa). RESULTS: Forty-eight patients were included (May 2017-March 2018): 2 GT1b, 24 GT1a and 22 GT4. HCV-RNA>800000UI in 63% and medium liver stiffness 4.9kPa. The SVR was 98%, one patient failed due to poor adherence. 67% of patients had adverse effects, but only 16% treatment related. The most frequent side effects were gastrointestinal (19%), related with the central nervous system (18%), respiratory (16%) and systemic symptoms (15%). During one year of follow-up post-therapy, 4 AHC and 18 patients with sexually transmitted diseases (STD) were diagnosed. CONCLUSIONS: Treatment with Elbasvir/Grazoprevir in this scenario is highly effective and safe. Patients with risky sexual practices must remain linked to the medical care system to detect new STD and HCV reinfection.

RESUMO

HIV co-infection has been suggested to play a deleterious role on the pathogenesis of liver fibrosis among vertically HCV-infected children. The aim of this study was to describe the longitudinal evolution of vertically acquired HIV/HCV co-infection in youths, in comparison with HCV infection alone. This was a retrospective, multicentre study including vertically HIV/HCV-co-infected patients and age- and sex-matched vertically HCV-mono-infected patients. Progression to advanced liver fibrosis, defined as F3 or more by elastography or METAVIR biopsy staging, and response to treatment were compared by means of univariate and multivariate regression analyses and Cox regression models. Sixty-seven co-infected patients were compared with 67 matched HCV-mono-infected patients. No progression to advanced liver disease was observed during the first decade. At a median age of 20.0 [19.0, 22.0] years, 26.7% co-infected vs 20% mono-infected had progressed to advanced fibrosis (P = .617). Peg-IFN/RBV for HCV treatment was given to 37.9% vs 86.6% (P-value < .001). At treatment initiation, co-infected patients were older (16.9 ± 4.1 vs 11.7 ± 4.5 years, P < .001), and 47.1% vs 7.1% showed advanced fibrosis (P < .003), with no differences in hard-to-treat genotype distribution. Sustained viral response was comparable between groups (43.5% vs 44.0%, P = .122). In vertically HIV/HCV-co-infected patients, the progression to liver fibrosis was rare during childhood. At the end of adolescence, over 25% of patients displayed advanced liver disease. Response to Peg-IFN/RBV was poor and comparable in both groups, supporting the need for fast access to early treatment with direct-acting antivirals against HCV for vertically co-infected patients.

RESUMO

There remains a substantial gap in our understandings of the life experiences of patients following HCV cure among HIV-HCV-co-infected people who inject drugs (PWID) and men who have sex with men (MSM), two key populations targeted for HCV elimination. We described the experiences and perspectives of HIV-positive PWID and MSM, HCV-cured following treatment with direct-acting antivirals (DAA). We used an exploratory sequential mixed approach using both qualitative data (semi-structured interviews with 27 PWID and 20 MSM) and quantitative data (self-administered questionnaires with 89 PWID) via the prospective ANRS CO13 HEPAVIH cohort. PWID reported improvements in physical health-related quality of life (HRQL) and self-reported symptoms following treatment, but no significant change in mental HRQL. During interviews, several MSM, more recently diagnosed with HCV, expressed less concern regarding HCV than HIV infection and interpreted improvements in their overall well-being after HCV cure to be more related to a closer connection with healthcare providers than with viral elimination. By contrast, PWID, particularly those previously exposed to interferon-based treatments, described major improvements in their physical HRQL. Both MSM and PWID reported improvements in cognitive or psychological wellbeing, and a majority of them reported some degree of concern over potential HCV reinfection. To conclude, though health benefits of HCV cure concern both groups, HIV-infected PWID and MSM may have different representations and experiences following DAA treatment, related to their history with HCV. They are thus likely to benefit from holistic, post-treatment follow-up care that is responsive to their evolving health and social contexts.

RESUMO

In HIV patients, HCV co-infection has been associated with an increased risk of progressive multifocal leukoencephalopathy (PML). Furthermore, PML has also been described in patients with cirrhosis, whether related to HCV infection or not. We describe here the case of a HIV/HCV co-infected patient with cirrhosis who developed PML despite HIV suppression and CD4 cell count above 250/mm3 for 2 years. Immunological studies performed at onset of PML and before HCV therapy showed a decrease in naïve CD4 cells (CD45RA+CCR7+CD27+ CD4+ T cells - 23% cells, i.e. 75/mm3) and NK lymphopenia with abnormal and activated NK cells (CD3- CD16+ and/or CD56+) (5% lymphocytes, i.e. 58/mm3, CD69 91%, NKp30 26%). This impaired immunity, possibly related to HIV infection, or HCV infection or cirrhosis, or a combination thereof, could have led to the development of PML.

RESUMO

Food insecurity may lead to depressive symptoms, which are known to be associated with poor HIV related health outcomes. However, it is unclear to what extent food insecurity 'directly' affects these outcomes. We used data from the Food Security & HIV-HCV Sub-Study of the Canadian Co-Infection Cohort to assess the controlled direct effect. People experiencing severe food insecurity had 1.47 (95% CI 1.04-2.09) times the risk of having detectable HIV viral load and 0.94 (95% CI 0.87-1.02) fold change in CD4 count. After holding depressive symptoms constant, the association between severe food insecurity and HIV viral load was attenuated to a statistically non-significant level (RR 1.36, 95% CI: 0.95-1.96), whereas the association between severe food insecurity and CD4 count was unchanged. Depressive symptoms partially mediate the effect of severe food insecurity on HIV viral suppression; interventions focused on depressive symptoms alone may not be sufficient, however, to eliminate this effect.

RESUMO

BACKGROUND: HIV infection exacerbates the prognosis of HCV infection, with a faster progression of hepatitis. Hepatic fibrosis is the major disruption of the hepatic tissue architecture characterized by anarchic deposition and excess of the extracellular matrix. The objective of this study was to evaluate hepatic fibrosis in HIV/HCV co-infected individuals as compared to HCV mono-infected. METHODS: A total of 97 participants (mean age 60.2 ± 14.3 years and 0.76 male/female sex ratio) was enrolled in a study conducted in Yaoundé, Cameroon from November 2018 to January 2019. Liver fibrosis was assessed by the APRI score (Aspartate Aminotransferase or AST/Platelet Ratio Index) which identifies the stage of fibrosis as classified by the Metavir system (F0 to F4). CD4 counts and plasmatic HIV viral load of HIV/HCV co-infected individuals were determined and the correlation between hepatic fibrosis and immuno-virological status established. Statistical analysis was done using Microsoft Excel 2016 and EpiInfo7 software. RESULTS: A high proportion (63.6%) of HIV/HCV co-infected participants had an abnormal AST level: 73.6 ± 45.8 IU/L as compared to 58.5 ± 39.3 IU/L (59.3%) among HCV mono-infected participants. The frequency of thrombocytopenia was 63.6% with a mean platelet count of 137 ± 50 ×  103 IU/L in HIV/HCV co-infected participants as compared to 176 ± 67 × 103 IU/L in HCV mono-infected participants (38.4%). The progression of hepatic fibrosis in participants with clinically significant fibrosis: F2, F3 and F4 was higher among HIV/HCV co-infected and the mean APRI score was 1.7 ± 1.4 versus 1 ± 0.8 among HCV mono-infected (26.7%). All participants (100%) with detectable HIV viral load had clinically significant fibrosis compared to 33.4% in those with undetectable HIV viral load (p = 0.55). Only 42.9% participants with CD4 >  500 cells/µL had clinically significant fibrosis (p = 0.72) while 100% participants with CD4 <  200 cells/µL had clinically significant fibrosis (p = 0.58). CONCLUSIONS: A high level of AST combined with thrombocytopenia (APRI score > 1.5) is an indicator of hepatic fibrosis in HIV/HCV co-infected individuals. Because of its non-invasive and less costly nature, the APRI score can be a suitable biomarker to monitor hepatic fibrosis in HIV/HCV co-infected individuals in resource constrained settings.

RESUMO

To investigate the association between diabetes and HCV infection in persons living with HIV and to determine the impact of diabetes on the occurrence of serious liver events (SLEs) and liver-related deaths (LRDs) among HIV/HCV-co-infected patients. Patients were included if they had at least one follow-up visit. In a cross-sectional analysis among all HIV patients, we have investigated the association between diabetes and HCV infection. A further longitudinal analysis was performed in the population of HIV/HCV-co-infected free from SLE with FIB-4 index < 3.25 at baseline, using the following endpoints: (A) first event between SLE and LRD; (B) liver fibrosis progression defined as the first of two consecutive FIB-4 > 3.25; (C) first event between SLE, LRD, and liver fibrosis progression. Data from 15,571 HIV patients were analyzed: 2944 (18.9%) were HCV-Ab positive, and 739 (4.7%) presented a diagnosis of diabetes at their last follow-up. Among HIV/HCV-co-infected population, 107 patients had a diagnosis of diabetes. Viremic HCV-co-infected patients had 3-fold risk of diabetes onset than HCV-uninfected patients. On HIV/HCV-co-infected population, 85 SLEs/LRDs occurred over 20,410 person-years of follow-up (PYFU), for an incidence rate of 4.2/1000 PYFU (95%CI 3.4-5.2). Diabetic patients had 3-fold risk of pooled SLE and LRD than patients without diabetes. Furthermore, viremic HCV infection was independently associated with a higher risk of SLE/LRD (aIRR 3.35 [95%CI 1.14-9.83]). In HIV-infected patients, viremic HCV co-infection is a strong predictor of diabetes. Among HIV/HCV-co-infected population, diabetic patients showed an increased risk of SLE/LRD compared with those without diabetes.

RESUMO

BACKGROUND: Over the last 20 years, Hepatitis C virus (HCV) infection prevalence has dramatically increased among HIV-infected men who have sex with men (MSM) in many countries worldwide. It is suspected that this increase is primarily driven by sexual behaviours linked to blood exposure. Monitoring these behaviours is crucial to understand the drivers of the epidemic. This study assessed the prevalence of chronic HCV infection among MSM attending gay venues and associated chronic HCV risk factors. HCV screening and associated factors were described. METHODS: The cross-sectional survey PREVAGAY, based on time-location sampling, was conducted in 2015 among MSM attending gay venues in 5 French metropolitan cities. A self-administered questionnaire was completed and capillary whole blood on dried blood spots (DBS) collected. Possible factors associated with chronic HCV prevalence and with HCV screening in the previous year were investigated using Poisson regression. RESULTS: Chronic HCV infection prevalence from DBS analysis was 0.7% [IC95%: 0.3-1.5] in the study's 2645 participants and was 3.0% [1.5-5.8] in HIV-positive MSM. It was significantly higher in those who reported the following: (lifetime) slamming (with or without the sharing of injection equipment); (during the previous year) fisting and chemsex, unprotected anal intercourse with casual partners, using gay websites and/or of mobile-based GPS applications, and having more than 10 sexual partners. Only 41.3% [38.2-44.5] of the participants reported HCV screening during the previous year. Screening was significantly more frequent in MSM under 30 years of age, those who were HIV-positive, those vaccinated against hepatitis B and meningococcus C, and those who reported the following (during the previous year): more than 10 sexual partners, at least one sexually transmitted infection and fisting. CONCLUSION: Chronic HCV infection prevalence in MSM attending gay venues was significantly higher in HIV-positive MSM and in those with risky sexual behaviours. Reflecting current screening recommendations for specific populations, previous HCV screening was more frequent in HIV-positive individuals and those with risky sexual behaviours. Nevertheless, HCV screening coverage needs to be improved in these populations. Comprehensive medical management, which combines screening and linkage to care with prevention strategies, is essential to control HCV among MSM.

RESUMO

BACKGROUND: Alcohol consumption is a known risk factor for liver disease in HIV-infected populations. Therefore, knowledge of alcohol consumption behaviour and risk of disease progression associated with hazardous drinking are important in the overall management of HIV disease. We aimed at assessing the usefulness of routine data collected on alcohol consumption in predicting risk of severe liver disease (SLD) among people living with HIV (PLWHIV) with or without hepatitis C infection seen for routine clinical care in Italy. METHODS: We included PLWHIV from two observational cohorts in Italy (ICONA and HepaICONA). Alcohol consumption was assessed by physician interview and categorized according to the National Institute for Food and Nutrition Italian guidelines into four categories: abstainer; moderate; hazardous and unknown. SLD was defined as presence of FIB4 > 3.25 or a clinical diagnosis of liver disease or liver-related death. Cox regression analysis was used to evaluate the association between level of alcohol consumption at baseline and risk of SLD. RESULTS: Among 9542 included PLWHIV the distribution of alcohol consumption categories was: abstainers 3422 (36%), moderate drinkers 2279 (23%), hazardous drinkers 637 (7%) and unknown 3204 (34%). Compared to moderate drinkers, hazardous drinking was associated with higher risk of SLD (adjusted hazard ratio, aHR = 1.45; 95% CI: 1.03-2.03). After additionally controlling for mode of HIV transmission, HCV infection and smoking, the association was attenuated (aHR = 1.32; 95% CI: 0.94-1.85). There was no evidence that the association was stronger when restricting to the HIV/HCV co-infected population. CONCLUSIONS: Using a brief physician interview, we found evidence for an association between hazardous alcohol consumption and subsequent risk of SLD among PLWHIV, but this was not independent of HIV mode of transmission, HCV-infection and smoking. More efforts should be made to improve quality and validity of data on alcohol consumption in cohorts of HIV/HCV-infected individuals.

RESUMO

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.

RESUMO

BACKGROUND & AIMS: The recommended combination of pangenotypic direct-acting antivirals (DAAs) for the treatment of hepatitis C virus (HCV) associates the co-formulation of 2 or 3 second-generation DAAs. In the so-called "special populations" defined as patients with chronic kidney disease (CKD), HCV/HIV co-infection, HCV/HBV co-infection and an unsuccessful previous DAA regimen, these combinations have a high antiviral potency (sustained virologic response (SVR) > 95%), fair tolerance and a reduced pill burden. METHODS: We have taken into account the scientific evidence on the treatment of "special populations", in particular from the RUBY 1-2 trials, EXPEDITION 2-4 study, C-WORTHY trial, ASTRAL 5, POLARIS 1-4 studies, MAGELLAN 1 and REVENGE study. RESULTS: CKD and HCV/HIV co-infection are not predictors of a non-viral response. The glecaprevir/pibentrasvir (Maviret) combination appears to be the first-line therapy for CKD patients while the sofosbuvir/vlpatasvir/voxaliprevir (Sovesi) combination is the first-line option for DAAs failures. Both are effective in patients with HIV-or HBV-HCV co-infection and should be chosen according to the potential drug-drug interaction profile. CONCLUSIONS: The notion of "special populations" is no longer pertinent with pangenotypic DAAs combinations. International guidelines recommend treating all infected patients and the next challenge is not the therapeutic choice, but to improve the limitations for screening and access to care in HCV infection.

RESUMO

Depressive symptoms are associated with poor HIV viral control and immune recovery among people living with HIV. However, no prior studies assessed this association exclusively among people co-infected with HIV-hepatitis C virus (HCV). While people with HIV only and those with HIV-HCV co-infection share many characteristics, co-infected people may become more susceptible to the effects of depressive symptoms on health outcomes. We assessed this association exclusively among people co-infected with HIV-HCV in Canada using data from the Food Security & HIV-HCV Sub-Study (FS Sub-Study) of the Canadian Co-Infection Cohort (CCC). Stabilized inverse probability weighted marginal structural model was used to account for potential time-varying confounders. A total of 725 participants were enrolled between 2012 and 2015. At baseline, 52% of participants reported depressive symptoms, 75% had undetectable HIV viral load, and median CD4 count was 466 (IQR 300-665). People experiencing depressive symptoms had 1.32 times (95% CI: 1.07, 1.63) the risk of having detectable HIV viral load, but had comparable CD4 count to people who did not experience depressive symptoms (fold change of CD4 = 0.96, 95% CI: 0.91, 1.03). Presence of depressive symptoms is a risk factor for incomplete short-term HIV viral suppression among people co-infected with HIV-HCV. Therefore, depressive symptoms screening and related counseling may improve HIV related health outcomes and reduce HIV transmission.

RESUMO

Patients co-infected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are at high risk of liver disease progression. We report a favorable safety profile and SVR12 rates of 96.7% among HIV/HCV co-infected patients participating in an Italian compassionate-use program of ombitasvir/paritaprevir/ritonavir + dasabuvir (OBV/PTV/r + DSV) ± ribavirin (RBV).

RESUMO

BACKGROUND & AIMS: There is little data available on the use of new oral direct-acting antiviral (DAA) regimens to treat human immunodeficiency virus and hepatitis C virus (HIV/HCV) co-infected patients in real-life settings. Here, the efficacy and safety of all-oral DAA-based regimens in HIV/HCV-co-infected patients enrolled in the French nationwide ANRS CO13 HEPAVIH observational cohort are reported. METHODS: HIV/HCV-co-infected patients enrolled in the ANRS CO13 HEPAVIH observational cohort were included if they began an all-oral DAA-based regimen before 1st May 2015 (12-week regimens) or 1st February 2015 (24-week regimens). Treatment success (SVR12) was defined by undetectable HCV-RNA 12weeks after treatment cessation. Exact logistic regression analysis was used to identify factors associated with SVR12. RESULTS: A total of 323 patients (74% men) with a median age of 53years were included, 99% of whom were on combination antiretroviral therapy (cART). HIV RNA load was <50 copies/ml in 88% of patients; median CD4 cell count was 540/mm3; 60% of patients were cirrhotic; 68% had previously received unsuccessful anti-HCV treatment. cART was protease inhibitor (PI)-based in 23%, non-nucleoside reverse transcriptase inhibitor (NNRTI)-based in 15%, and integrase inhibitor (II)-based in 38%, while 24% of patients received other regimens. The SVR12 rate was 93.5% overall (95% confidence interval [CI]: 90.2-95.9), 93.3% (88.8-96.4) in patients with cirrhosis and 93.8% (88.1-97.3) in patients without cirrhosis. The SVR12 rates were 93.1% (84.5-97.7), 91.8% (80.4-97.7) and 95.8% (90.5-98.6) respectively, in patients receiving PI-based, NNRTI-based and II-based cART. In adjusted analysis, SVR12 was not associated with HIV RNA load, the cART regimen, cirrhosis, prior anti-HCV treatment, the duration of anti-HCV therapy, or ribavirin use. The most common adverse effects were fatigue and digestive disorders. CONCLUSIONS: New all-oral DAA regimens were well-tolerated and yielded high SVR12 rates in HIV/HCV-co-infected patients. LAY SUMMARY: We evaluated efficacy and safety of all-oral DAA regimens in a large French nationwide observational cohort study of HIV/HCV co-infected patients. Sustained virological response 12weeks after treatment cessation was 93.5% overall. The all-oral DAA regimens were well-tolerated and most common adverse effects were fatigue and digestive disorders.

RESUMO

BACKGROUND & AIMS: Hepatic steatosis (HS) seems common in patients infected with human immunodeficiency virus (HIV). However, the relative effect of HIV, as well as hepatitis C virus (HCV) in those co-infected, and the influence of HS on liver fibrosis progression are unclear. METHODS: The LIVEr disease in HIV (LIVEHIV) is a Canadian prospective cohort study using transient elastography and associated controlled attenuation parameter (CAP) to screen for HS and liver fibrosis, in unselected HIV-infected adults. HS progression was defined as development of any grade HS (CAP ⩾248dB/m), or transition to severe HS (CAP >292dB/m), for those with any grade HS at baseline. Fibrosis progression was defined as development of significant liver fibrosis (liver stiffness measurement [LSM] >7.1kPa), or transition to cirrhosis (LSM >12.5kPa) for those with significant liver fibrosis at baseline. Cox regression analysis was used to assess predictors of HS and fibrosis progression. RESULTS: A prospective cohort study was conducted, which included 726 HIV-infected patients (22.7% HCV co-infected). Prevalence of any grade HS did not differ between HIV mono-infected and HIV/HCV co-infected patients (36.1% vs. 38.6%, respectively). 313 patients were followed for a median of 15.4 (interquartile range 8.5-23.0) months. The rate of HS progression was 37.8 (95% confidence interval [CI] 29.2-49.0) and 21.9 (95% CI 15.6-30.7) per 100 person-years in HIV mono-infection and HIV/HCV co-infection, respectively. HCV co-infection was an independent negative predictor of HS progression (adjusted hazard ratio [aHR] 0.50, 95% CI 0.28-0.89). HS predicted liver fibrosis progression in HIV mono-infection (aHR 4.18, 95% CI 1.21-14.5), but not in HIV/HCV co-infection. CONCLUSION: HS progresses faster and is associated with liver fibrosis progression in HIV mono-infection but not in HIV/HCV co-infection. Lay summary: Fatty liver is the most frequent liver disease in Western countries. People living with HIV seem at high risk of fatty liver due to frequent metabolic disorders and the long-term effects of antiretroviral therapy. However, due to the invasiveness of liver biopsy, the traditional method of diagnosing fatty liver, there are few data regarding its frequency in people living with HIV. In this study, we used a non-invasive diagnostic tool to analyze the epidemiology of fatty liver in 726 HIV+ patients. We found that fatty liver affects over one-third of people living with HIV. When followed over time, we found that HIV+ patients without HCV co-infection develop fatty liver more frequently than those co-infected with HCV.

RESUMO

Food insecurity (FI) is associated with depressive symptoms among HIV mono-infected people. Our objective was to examine to what extent this association holds among HIV-hepatitis C virus (HCV) co-infected people. We used data from a prospective cohort study of HIV-HCV co-infected people in Canada. FI was measured using the ten-item adult scale of Health Canada's Household Food Security Survey Module and was classified into three categories: food secure, moderate FI, and severe FI. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CES-D-10) and was classified into absence or presence of depressive symptoms. FI, depressive symptoms, and other covariates were updated every 6 months. The association between FI and depressive symptoms was assessed using a stabilized inverse probability weighted marginal structural model. The study sample included 725 HIV-HCV co-infected people with 1973 person-visits over 3 years of follow up. At baseline, 23% of participants experienced moderate food insecurity, 34% experienced severe food insecurity and 52% had depressive symptoms. People experiencing moderate FI had 1.63 times (95% CI 1.44-1.86) the risk of having depressive symptoms and people experiencing severe FI had 2.01 times (95% CI 1.79-2.25) the risk of having depressive symptoms compared to people who were food secure. FI is a risk factor for developing depressive symptoms among HIV-HCV co-infected people. Food supplementation, psychosocial support and counseling may improve patient health outcomes.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) infection is a pandemic causing disease; more than 185 million people are infected worldwide. An HCV antibody (Ab) prevalence of 6.0% was estimated in Central African countries. The study aimed at providing HCV prevalence estimates among pregnant women in Rwanda. METHODS: HCV surveillance through antibody screening test among pregnant women attending antenatal clinics was performed in 30 HIV sentinel surveillance sites in Rwanda. RESULTS: Among 12,903 pregnant women tested at antenatal clinics, 335 (2.6% [95% Confidence Interval 2.32-2.87]) tested positive for HCV Ab. The prevalence of HCV Ab in women aged 25-49 years was 2.8% compared to 2.4% in women aged 15-24 years (aOR = 1.3; [1.05-1.59]); This proportion was 2.7% [2.37-2.94] in pregnant women in engaged in non-salaried employment compared to 1.2% [0.24-2.14] in those engaged in salaried employment (aOR = 3.2; [1.60-6.58]). The proportion of HCV Ab-positive co-infected with HIV was estimated at 3.9% (13 cases). Women in urban residence were more likely to be associated with HCV-infection (OR = 1.3; 95%CI [1.0-1.6]) compared to those living in rural setting. CONCLUSION: HCV is a public health problem in pregnant women in Rwanda. Few pregnant women were co-infected with HCV and HIV. Living in urban setting was more likely to associate pregnant women with HCV infection.
