Abstract
OBJECTIVES Italy is a low-incidence region for hepatitis A; however, during the last 2 years an increase in the incidence of hepatitis A virus (HAV) infection was reported in Europe. The aim of this study was to describe this recent outbreak. METHODS We retrospectively analysed all cases of acute hepatitis A diagnosed at our laboratory between January 2010 and June 2017. We evaluated the following variables at the time of diagnosis: sex, age, nationality, glutamic oxaloacetic transaminase (GOT/AST), glutamic pyruvic transaminase (GPT/ALT), bilirubin concentration, international normalized ratio (INR) and the presence or absence of anti-HIV-1/2 antibodies. Hospitalization was also considered. We analysed these parameters using the χ2 test and Mann-Whitney U-test. RESULTS A total of 225 cases were analysed; 82.7% were in male patients, 94.2% were in Italians and the median age of the patients was 36.4 years. At diagnosis, the median GOT value was 306 U/L, the median GPT was 1389 U/L, and the median total bilirubin value was 5.88 mg/dL. Hospitalization was required for 142 patients, with a median duration of hospital stay of 8.5 days. In 2016-2017 we registered 141 cases, with a higher prevalence of male patients, higher GPT values and a higher prevalence of patients aged 20-39 years compared with older (2010-2015) cases. Homosexual intercourse was reported as the HAV risk factor in 70.2% of patients. HIV serology was available for 120 patients: 24 were HIV-positive, four of whom represented new diagnoses. HIV-positive patients showed lower bilirubin and GPT values and fewer hospitalizations than HIV-negative patients. CONCLUSIONS In 2016-2017, we saw a rise in the number of hepatitis A cases, with a higher prevalence of adult male patients. No significant differences regarding the prevalence of HIV coinfection emerged.

Abstract
Hepatitis A virus (HAV) is one of the most common infectious etiologies of acute hepatitis worldwide. The virus is known to be transmitted fecal-orally, resulting in symptoms ranging from asymptomatic infection to fulminant hepatitis. HAV can also be transmitted through oral-anal sex. Residents from regions of low endemicity for HAV infection often remain susceptible in their adulthood. Therefore, clustered HAV infections or outbreaks of acute hepatitis A among men who have sex with men and injecting drug users have been reported in countries of low endemicity for HAV infection. The duration of HAV viremia and stool shedding of HAV may be longer in human immunodeficiency virus (HIV)-positive individuals compared to HIV-negative individuals with acute hepatitis A. Current guidelines recommend HAV vaccination for individuals with increased risks of exposure to HAV (such as from injecting drug use, oral-anal sex, travel to or residence in endemic areas, frequent clotting factor or blood transfusions) or with increased risks of fulminant disease (such as those with chronic hepatitis). The seroconversion rates following the recommended standard adult dosing schedule (2 doses of HAVRIX 1440 U or VAQTA 50 U administered 6-12 mo apart) are lower among HIV-positive individuals compared to HIV-negative individuals. While the response rates may be augmented by adding a booster dose at week 4 sandwiched between the first dose and the 6-mo dose, the need of booster vaccination remain less clear among HIV-positive individuals who have lost anti-HAV antibodies.

Abstract
Surveillance systems for acute hepatitis C allow monitoring of disease incidence trends and transmission patterns. This study aimed to describe the epidemiological profile of reported cases of symptomatic acute hepatitis C in Italy after the achievement of blood supply safety. The incidence of symptomatic acute hepatitis C since 1991 was estimated. Risk factors for acute hepatitis C were analyzed for the period 2003-2010 through a case-control study within a population-based surveillance for acute viral hepatitis. From 1991 to 2010, the incidence decreased from 2 to 0.2 per 100,000, with a more evident decrease among persons aged 15-24 years. During 2003-2010, 1,053 cases were reported. Intravenous drug use (adjusted odds ratio [(adj) OR], 30.5; 95% confidence interval [CI], 18.9-49.1), cohabitation or sexual partnership with an hepatitis C virus (HCV) carrier ((adj) OR, 11.2; 95% CI, 6.6-19.2), nosocomial exposure ((adj) OR, 6.6; 95% CI, 4.6-9.4); unsafe sexual practices ((adj) OR, 3.1; 95% CI, 1.9-5.2), and cosmetic treatments with percutaneous exposure ((adj) OR, 1.7; 95% CI, 1.2-2.4) were independently associated with acute hepatitis C. Population attributable risk estimates indicated nosocomial exposure (39.6%) and intravenous drug use (30.5%) as responsible for most cases. In conclusion, the incidence of symptomatic acute hepatitis C is declining in Italy. Currently, the most important risk factors are: having an HCV-positive household or sexual partner, unsafe sexual practices, cosmetic percutaneous treatments, intravenous drug use, and nosocomial exposure; the latter two factors are responsible for most cases. Effective prevention programs for intravenous drug users and strict adherence to universal precautions in healthcare settings are needed.

Abstract
BACKGROUND & AIMS Several outbreaks of hepatitis A affecting homosexual men have been reported in Europe. However, the prevalence of HIV infection in patients affected by hepatitis A has not been extensively studied and hepatitis A is not considered as an indicator disease for routine HIV testing. METHODS We retrospectively analyzed all adult cases of acute hepatitis A, reported by the National Institute of Infectious Disease "L. Spallanzani", Rome-Italy, in 2002-2008. Data on HIV infection were obtained by chart review and cross-linkage with laboratory. Information on exposure to risk factors were collected from the standard questionnaire of the Local Health Unit. RESULTS We analyzed a total of 473 cases of hepatitis A, 368 (77.2%) males that accounted for 75% of all reported cases in Rome, aged 25-64 years (same gender distribution). During the study period, we diagnosed a high proportion of cases among male individuals (78%). Among the male patients, HIV serology was available for 203/368 (55.2%). The overall HIV prevalence was 15.2% (56/368); it was significantly associated with same gender sex and was significantly higher than that observed among patients with hepatitis B (4.0%). CONCLUSIONS We found a high HIV prevalence, associated with same gender sex, among adult male patients diagnosed with hepatitis A in the period 2002-2008, except for 2006. Our data suggest that in a low incidence area for hepatitis A, with a constant high proportion of cases among male individuals, all individuals with acute hepatitis A should be routinely offered an HIV test.

Abstract
BACKGROUND Acute Hepatitis A Virus (HAV) is reported to be an emergent problem in several developed countries. OBJECTIVES AND STUDY DESIGN The aim of this study was to analyse the HAV strains circulating among individuals with acute HAV infection, apparently transmitted by different routes, in several districts of Tuscany in central Italy, during the year 2008. RESULTS An outbreak of acute HAV infection occurred from May to August 2008 in Arezzo; 32 individuals were admitted to the hospital, in 25 of them at least a linkage with an infected food handler and/or household contacts was reported and in 3 homosexuality was a possible risk factor. In Florence, from January 2008 to August 2008, 41 individuals mainly homosexual men were admitted to two hospitals with the diagnosis of acute HAV. The phylogenetic analysis of VP1/2A region of HAV was used to characterize these HAV isolates. All viral sequences were assigned to genotype IA. All clustered in the same branch (bootstrap 82%) of phylogenetic tree, thus indicating the same circulating isolate. Apart of one isolate from France and one from Germany which were similar with the "Tuscany" strain reported here, high heterogeneity with the other European HAV strains reported in the GenBank in the last years, was observed. CONCLUSION The detection of a unique HAV isolate circulating in different Tuscany districts, suggests sequential transmission of HAV infection in this geographical area through possible links among acute hepatitis cases. The application of safe food handling practices and vaccination of homosexual men may contribute to the prevention of HAV infection.

Abstract
The prevalence of hepatitis A virus (HAV) infection is high in developing countries, in which low standards of sanitation promote the transmission of the virus. In Latin America, which is considered an area of high HAV endemicity, most HAV-positive individuals are infected in early childhood However recent studies have shown that prevalence rates are decreasing. Herein, we review the data on HAV prevalence and outbreaks available in scientific databases. We also use official government data in order to evaluate mortality rates in Brazil over the last two decades. Studies conducted in the northernmost regions of Brazil have indicated that, although improved hygiene has led to a reduction in childhood exposure to HAV, the greatest exposure still occurs early in life. In the Southeastern region, the persistence of circulating HAV has generated outbreaks among individuals of low socioeconomic status, despite adequate sanitation. Nationwide, hepatitis A mortality rates declined progressively from 1980 to 2002. During that period, mortality rates in the Northern region consistently exceeded the mean national rate and those for other regions. Excluding the North, the rates in all regions were comparable. Nevertheless, the trend toward decline observed in the South was paralleled by a similar trend in the North.
