Abstract
BACKGROUND Studies have shown that the immunosuppression induced by the human immunodeficiency virus (HIV) accelerates the natural history of liver disease associated with hepatitis C virus (HCV), with 3- to 5-fold higher odds of coinfected individuals developing cirrhosis. However, estimates of the seroprevalence of hepatitis C among people living with HIV/acquired immune deficiency syndrome (AIDS) (PLHA) in Latin America and the Caribbean (LAC) are widely variable. METHODS We performed a systematic review to estimate the seroprevalence of HCV among PLHA. We searched studies on HIV and HCV infections in LAC included in the PubMed, LILACS and Embase databases in December of 2014 with no time or language restrictions. The following combinations of search terms were used in the PubMed and Embase databases: (HIV OR Acquired Immunodeficiency Syndrome Virus OR AIDS OR HTLV OR Human Immunodeficiency Virus OR Human T Cell) AND (HCV OR HEPATITIS C OR HEPATITIS C VIRUS OR HEPACIVIRUS) AND (name of an individual country or territory in LAC). The following search terms were used in the LILACS database: (HIV OR AIDS OR Virus da Imunodeficiencia Humana) AND (HCV OR Hepatite C OR Hepacivirus). An additional 11 studies were identified through manual searches. A total of 2,380 publications were located, including 617 duplicates; the remaining articles were reviewed to select studies for inclusion in this study. RESULTS A total of 37 studies were selected for systematic review, including 23 from Brazil, 5 from Argentina, 3 from Cuba, 1 from Puerto Rico, 1 from Chile, 1 from Colombia, 1 from Mexico, 1 from Peru and 1 from Venezuela. The estimated seroprevalence of HCV infection varied from 0.8 to 58.5 % (mean 17.37; median 10.91), with the highest in Argentina and Brazil and the lowest in Venezuela and Colombia. CONCLUSIONS Investigation of HCV infection among PLHA and of HIV infection among people living with HCV is highly recommended because it allows for better follow up, counseling and treatment of HIV/HCV-coinfected patients. Future studies with larger sample sizes are needed in both South and Central America to understand and address the risk factors associated with the acquisition of infection.

Abstract
SUMMARY Objective: to determine the prevalence and epidemiological factors associated with hepatitis (HCV) coinfection in human immunodeficiency virus (HIV) patients from Curitiba and the metropolitan region. Methods: a study with 303 HIV+ patients, mean age 41.2 years (18-73); 50.5% men, followed at the Hospital de Clínicas, Universidade Federal do Paraná, between April 2008 and March 2009. Clinical and epidemiological data were obtained through questionnaires and retrospective analysis of medical records. Anti-HCV antibodies were detected by chemiluminescence immunoassay. Results: a total of 12.9% of HIV+ patients were positive for anti-HCV antibodies, 64.1% were men and 35.9% women, with mean age of 44.5 years (24-66). The frequency of HCV among men was 16.7% and among women 9.1% (p=0.06). HCV prevalence was associated to HIV infection when compared to the general population (p<10-6, OR=100.4; 95CI=13.7-734.9). The parenteral route of transmission was the most frequent among coinfected patients (46.1%), and the sexual transmission among HIV+/HCV- (71.8%) (p=0.02, OR=0.2; 95CI=0.1-0.7). The frequency of intravenous drug users was higher among the coinfected patients (61.5%) compared to the non coinfected (12.6%) (p<10-6, OR=11.1; 95CI=4.5-27.7). Conclusion: the prevalence of coinfection with HCV in HIV+ patients is 12.9%, 88 times higher than in the general population in Curitiba. The most frequent route of transmission in the coinfected patients is parenteral, but the sexual route is also representative (34.6%).

Abstract
This study aimed to estimate the prevalence of infection by the hepatitis B virus (HBV) and hepatitis C virus (HCV) in people infected by the human immunodeficiency virus (HIV) and analyze sociodemographic and behavioral factors associated with such co-infection. A cross-section study was performed in 495 individuals treated at a public center in the city of Goiânia. Participants were interviewed and blood collected for evaluation of serological and molecular markers for HBV and HCV. The rate of exposure to HBV was 33.5% (95% CI 29.4–37.9). Nineteen patients (3.8%) were diagnosed as HBV carriers, of whom 68.4% were HBV DNA positive. The prevalence of anti-HCV was 9.7% (95% CI 7.3–12.7). Genotype 1a was identified in 72.7% of the PCR samples positive for HCV. Co-infection by all three viruses was 4.4% (95% CI 2.9–6.8). Being, male, aged ≥40 years, history of sexually transmitted disease (STD), and having homosexual practices were independently associated with the presence of markers of HBV exposure. A history of injectable drugs use and STDs showed association with HCV seropositivity. Approximately 50% of participants were not aware of their HBV and HCV serostatus. The results obtained may contribute to assess the burden of viral hepatitis in people living with HIV and to guiding preventive measures for more vulnerable groups.

Abstract
In 2009, we conducted a case-control study to explore the routes of HCV transmission in people living with HIV/AIDS (PLHIV) in Cambodia. Cases were HCV/HIV co-infected patients (who tested RT-PCR positive for HCV-RNA or had confirmed presence of HCV antibodies) (n = 44). Controls were HIV mono-infected patients, with no HCV antibodies (n = 160). They were recruited among the PLHIV presenting at one national reference centre of HIV/AIDS. Multivariate analysis showed that factors associated with the co-infection were the age older than 50 years (OR 5.4, 95 % confidence interval (CI) 1.5-19.6), the exposure to multiple parenteral infusions before the year 2000 (OR 3.4, 95 % CI 1.5-7.6), to surgery (OR 2.6, 95 % CI 1.2-5.7) and to fibroscopy (OR 2.4, 95 % CI 1.0-5.7). These results show the need to implement HCV screening in PLHIV, to support the implementation of national infection control guidelines, and to reinforce public awareness on the risks linked to parenteral medications.

Abstract
The hepatitis C virus and human immunodeficiency virus share the same transmission routes, which makes co-infection an unfavorable condition for the natural history of both viral diseases. In this context, it should be highlighted that the knowledge of the extent of co-infection and associated risk factors is a vital tool for prevention and control over infectious diseases. The aim of this study was to review the literature, seeking to examine the prevalence of human immunodeficiency virus/hepatitis C virus co-infection reported in studies conducted in Brazil, and identify the main risk factors associated with co-infection. The electronic search was conducted in the Medline, Lilacs and SciELO databases. The following keywords were used: human immunodeficiency virus and Hepatitis C or hepatitis C virus and Brazil. The search led to 376 articles, of which 69 were selected for data extraction. We excluded animal studies, reports or case series, review articles, letters to the editor, other types of hepatitis and those studies in which co-infected patients were intentionally selected for comparison to single infected individuals. As a result, 40 articles were reviewed. The majority of the population in these studies was male (71%) and young adults, with a mean age of 26.7 years. The prevalence of hepatitis C virus co-infection among individuals living with human immunodeficiency virus in the studies conducted in Brazil ranged from 3.3% (serum samples) to 82.4% (drug users), with an average of 20.3%. The findings reveal that the prevalence of human immunodeficiency virus/hepatitis C virus co-infection is highly variable, depending on the characteristics of the study population. Risk factors associated with human immunodeficiency virus/hepatitis C virus co-infection were injection drug use and blood transfusion.

Abstract
BACKGROUND/AIMS There are conflicting data regarding the incidence and factors implicated in the spontaneous clearance of hepatitis C virus (HCV) after acute infection. The aim of this study was to determine the epidemiological factors that predict the resolution of acute HCV infection without therapy in patients with human immunodeficiency virus (HIV) infection. METHODS We conducted a retrospective, multivariate analysis of epidemiological data from HIV-infected patients presenting from 2000 to 2007 with evidence of past or present HCV infection. Data were collected from one American and two European HIV treatment clinics. A final cohort of 769 HIV-infected patients referred for treatment with available test results for antibody to HCV, HCV RNA, and hepatitis B surface antigen were included for the analysis. We calculated spontaneous clearance rates based on race, geographical location, gender, transmission risk factors, and hepatitis B virus coinfection. RESULTS Patients who admitted to a history of injection drug use spontaneously cleared the HCV infection significantly less often (11.6%) than those in whom sexual transmission was the presumed route of HCV infection (21.9%) (p=0.004). This difference was more pronounced when heterosexual contact as the source of infection was analyzed separately. Multivariate analysis identified heterosexual HCV transmission (OR 2.81, 95% CI 1.55-5.09) and hepatitis B surface antigen carrier status (OR 10.3, 95% CI 4.29-24.73) as independent factors predicting spontaneous HCV clearance. No differences according to gender, race or geographical origin were observed. CONCLUSIONS In summary, sexual transmission, particularly heterosexual, and hepatitis B virus coinfection were the only factors associated with spontaneous HCV clearance in this HIV-infected population.
