Authors present 6 cases of abdominal bleeding associated with COVID-19, representing 1.35% of all hospitalized COVID-19 patients and hypothesize that there could be, although not very frequently, a relationship between SARS-CoV2 and bleeding. They excluded a side effect of the low molecular weight heparin therapy that all patients underwent during the course of the disease or other possible causes. Alterations of the coagulation state or a weakness of the vascular wall due toa presumed endotheliitis SARS-CoV-2 infection induced, are hypothesized by the authors. Investigation and follow-up for possible hemorrhagic problems in patients with COVID-19 is recommended. In particular, clinicians should be vigilant about retroperitoneal hemorrhage in COVID-19 patients. In addition to the fact that these patients are being treated with anticoagulants, anemia and abdominal pain are the signs that should lead us to suspect this type of haemorrhage. More studies are needed to understand if COVID-19 can be directly associated with bleeding. (www.actabiomedica.it)

Recent introduction of direct antiviral agents (DAAs) has completely changed the scenario regarding hepatitis C virus (HCV) treatment. Certain countries' economic health programs prioritize DAAs according to specific clinical features of HCV-infected patients. The aim of this study was to define epidemiological, demographic and clinical characteristics of HCV-infected patients in the Tuscany region of central Italy.We enrolled HCV patients with chronic viral hepatitis who were referred to the outpatient services of 16 hospitals in Tuscany from 1 January 2015 to 31 December 2015. Case report forms contained patient information including main demographic data, blood chemistry data, viral hepatitis markers, instrumental evaluations (liver biopsy or transient elastometry, liver ultrasound), eligibility for DAAs, and liver transplantation or therapy already in progress.Of all patients considered, 2919 HCV patients were enrolled (mean age: 57.44 ± 15.15; 54% males, 46% females). All routes of transmission were well represented (intravenous drug use in 20.7%; nosocomial/dental care in 20.6%; and coagulation factors/blood transfusions in 13.3%). Diabetes was the highest represented comorbidity (20.8%), followed by metabolic syndrome (15.5%) and ischemic heart disease (6.2%). The most prevalent HCV genotypes were 1b (47.4%) and 2 (16.5%). In the whole cohort of patients, 32.8% were cirrhotic (40 patients were listed for liver transplantation). Signs of portal hypertension were present mostly in the group older than 45 years (92.3%). Extrahepatic HCV-related diseases were present in 13.3% of cases (cryoglobulinemic syndrome in 58.3% and B-cell non-Hodgkin's lymphoma in 10.5%).Our study provides evidence of a high prevalence of epidemiological changes in HCV infection with a major prevalence of advanced liver disease, such as portal hypertension, in this elderly cohort of patients.

AIM To build a regional database of chronic patients to define the clinical epidemiology of hepatitis B virus (HBV)-infected patients in the Tuscan public health care system. METHODS This study used a cross-sectional cohort design. We evaluated chronic viral hepatitis patients with HBV referred to the outpatient services of 16 hospital units. Information in the case report forms included main demographic data, blood chemistry data, viral hepatitis markers, instrumental evaluations, and eligibility for treatment or ongoing therapy and liver transplantation. RESULTS Of 4015 chronic viral hepatitis patients, 1096 (27.3%) were HBV infected. The case report form was correctly completed for only 833 patients (64% males, 36% females; mean age 50.1 ± 15.4). Of these HBV-infected patients, 73% were Caucasian, 21% Asian, 4% Central African, 1% North African and 1% American. Stratifying patients by age and nationality, we found that 21.7% of HBV-infected patients were aged < 34 years (only 2.8% were Italian). The most represented routes of transmission were nosocomial/dental procedures (23%), mother-to-child (17%) and sexual transmission (12%). The most represented HBV genotypes were D (72%) and A (14%). Of the patients, 24.7% of patients were HBeAg positive, and 75.3% were HBeAg negative. Of the HBV patients 7% were anti-HDV positive. In the whole cohort, 26.9% were cirrhotic (35.8% aged < 45 years), and 47% were eligible for or currently undergoing treatment, of whom 41.9 % were cirrhotic. CONCLUSION Only 27.3% of chronic viral hepatitis patients were HBV infected. Our results provide evidence of HBV infection in people aged < 34 years, especially in the foreign population not protected by vaccination. In our cohort of patients, liver cirrhosis was also found in young adults.

s / Digestive and Liver Disease 48S (2016) e1–e17 e5 eGFR was ≥60mL/min/1.73m2 in 92 patients (93.8%) and between45and59mL/min/1.73m2 in6patients (6.1%).Glomerular involvement was found in 19 patients (19.4%), tubular involvement in 31 (31.6%) and they co-occurred in 10 patients (p=0.034). Subjects with glomerular or tubular involvement, or both, showed significantly lower eGFRvalues (p=0.005). AROC curvewasdrafted and a cut point of 90ml/min predicted renal involvement (RI) (sensitivity 63%, specificity 75%), although it was unable to distinguish tubular vs glomerular involvement (p=0.914). Patients with RI were older, had higher ACR and 1MCR levels and exhibited a more severe KDIGO stage. No association was found between RI and: HCV-RNA levels, liver stiffness and liver function tests. L-FABP andKIM-1 levelswere significantlyhigher inpatientswithRI. Tubular involvement was significantly associated with increased levels of L-FABPandKIM-1,while glomerular involvementwas associated only with high L-FABP level. Conclusion: Tubular and/or glomerular involvement are quite frequent in HCV cirrhotic patients. The occurrence of eGFR

Dear Sirs:The aim of anti-HIV treatment in pregnancy is the suppres-sion of the HIV-1 RNA viral load in the plasma beforedelivery [1] to prevent mother-to-child transmission of theinfection. The achievement of this outcome may be compli-cated in pregnant women who have been treated with mul-tiple drugs by the lack of active drugs available. Althoughthere are limited data on the use of the integrase inhibitorraltegravir in pregnancy, the availability of this drug isimportant in the management of multidrug-resistant virusin pregnant women.We describe a case of a 22-year-old woman who acquiredthe infection via vertical transmission and who has beenfollowed up at our Centre since March 2009. Past antiretro-viral treatments include numerous drugs; the historical ge-notypic resistance test showed mutations in the regions ofreverse transcriptase (41L, 74V, 101Q, 103N, 103S, 108I,115F, 179I, 184V, 215D, 215N, 215S, 215Y) and protease(36I, 63P). These mutations confer resistance or poor effi-cacy to all the nucleoside/nucleotide reverse transcriptaseinhibitors and non-nucleoside reverse transcriptase inhibi-tors except etravirine.Since April 2009 the patient has received treatment withtenofovir/emtricitabine (fixeddosecombination)plusdaruna-vir/ritonavir (600/100 mg twice daily) plus raltegravir(400mgtwice daily).

Mesalazine therapy for ulcerative colitis has been reported to be effective and safe. Rare cases of mesalazine-induced renal, pancreatic, myo-pericardial, pleuro-pulmonary and haematological toxicity have been described separately. We report a case characterized by the simultaneous presence of fever, pericarditis, peripheral eosinophilia, eosinophilic pneumonia, anaemia and haematuria (together with proteinuria and leukocyturia) due to mesalazine treatment in a patient with ulcerative colitis. No clinical response had been obtained with corticosteroids and various antibacterial agents. When mesalazine treatment was suspended, all symptoms rapidly and totally disappeared, confirming the direct responsibility of this drug in causing these adverse events. We conclude that mesalazine can induce multi-organ hypersensitivity, which must always be considered as a possible adverse effect during treatment with this drug. To resolve this adverse event it is essential to discontinue mesalazine treatment.
