Background & Aims: Inadequate data are available about retreatment of nonresponders to interferon (IFN) and ribavirin. Thus, this study evaluated the efficacy and tolerability of a 48-week therapy ...with pegylated IFN-α-2b plus high-dose ribavirin in patients who have failed to respond to the combination. Treatment up to 48 weeks also in patients who have failed to clear hepatitis C virus (HCV) RNA by week 24 was also evaluated. Methods: One hundred forty-one patients who previously did not respond to IFN and ribavirin, 86% with genotype 1 or 4 infection, 52% with high viral load (>800.000 IU/mL), 22% with cirrhosis, were retreated with pegylated IFN-α-2b 1.5 μg/kg per week and ribavirin 1000–1200 mg/day for 48 weeks and followed up for 24 weeks. Results: By intent-to-treat analysis, 20% of patients achieved a sustained virologic response (SVR). SVR of genotype 1 patients was 19%. Independent predictors of SVR were low γ-glutamyltransferase levels (OR, 22.9; 95% CI: 6.6–79.6) and low viral load (OR, 3.8; 95% CI: 1.1–12.6). Twelve (23%) out of 51 patients who were HCV RNA positive after 24 weeks of therapy achieved a late virologic response (after week 24) and 5 (10%) of them, all with genotype 1, achieved an SVR. Genotype was not associated with response (P = .2) or with early response (P = .3). Conclusions: Retreatment with pegylated IFN-α-2b and ribavirin of multiexperienced and “difficult to treat” nonresponder patients produced a very promising SVR. Accurate selection of patients, such as those with low viral load and low γ-glutamyltransferase levels, and prolongation of therapy beyond 24 weeks also in HCV RNA-positive patients may further increase the rate of SVR.
Therapy of acute hepatitis C (AHC) has not yet been standardized and several issues are still unresolved. This open, randomized, multicenter trial aimed to assess the efficacy and safety of a 24‐week ...course of pegylated IFN (Peg‐IFN) alpha‐2b versus a 12‐week course of Peg‐IFN alpha‐2b alone or with ribavirin (RBV) in AHC patients. One hundred and thirty HCV acutely infected patients who did not spontaneously resolve by week 12 after onset were consecutively enrolled and randomized to receive Peg‐IFN alpha‐2b monotherapy (1.5 μg/kg/week) for 24 or 12 weeks (arm 1, n = 44 and arm 2, n = 43, respectively) or in combination with RBV (10.6 mg/kg/day) for 12 weeks (arm 3, n = 43). The primary endpoint was undetectable HCV RNA at 6‐month posttreatment follow‐up (sustained virological response; SVR). All patients were followed for 48 weeks after therapy cessation. HCV RNA levels were determined by real‐time polymerase chain reaction (limit of detection: 15 IU/mL) at the central laboratory at baseline, week 4, end of treatment, and 6 and 12 months posttreatment. Using an intent‐to‐treat analysis, overall SVR rate was 71.5%. In particular, an SVR was achieved in 31 of 44 (70.5%), 31 of 43 (72.1%), and 31 of 43 (72.1%) patients in arms 1, 2, and 3, respectively (P = 0.898). Sixteen patients (12.3%) prematurely discontinued therapy or were lost to follow‐up; thus, sustained response rates with per‐protocol analysis were 81.6%, 81.6%, and 81.6% for patients in arms 1, 2, and 3 respectively. With multivariate analysis, virologic response at week 4 of treatment was an independent predictor of SVR. Peg‐IFN alpha‐2b was well tolerated. Conclusion: Peg‐IFN alpha‐2b induces a high SVR in chronically evolving AHC patients. Response rates were not influenced by combination therapy or treatment duration. (Hepatology 2014;59:2101‐2109)

Abstract The Italian recommendations for the therapy of hepatitis B virus (HBV)-related disease were issued in 2008. Subsequently in 2008 the nucleotide analogue (NA) Tenofovir was approved for ...antiviral treatment. The introduction of this important new drug has called for the current guidelines update, which includes some additional revisions: (a) the indication for therapy is extended to mild liver fibrosis and the indication for treatment is graded as “possible”, “optional” or “mandatory” according to the fibrosis stage; (b) two different treatment strategies are described: first line definite duration treatment with interferon, long-term treatment of indefinite duration with NA; (c) the indication to follow either strategy is also based on the stage of liver fibrosis; (d) virological monitoring is modified to include the definitions of failure and of sustained virological response to interferon therapy; (e) the recommendation to use HBV DNA assays with high sensitivity and wide linear ranges is underlined (f) guidelines on post-treatment follow-up after finite treatment with NA, potential side effects of therapy and non-virological monitoring are defined; (g) definitions and treatment of patients without optimal response to NA are reported; (f) treatment and monitoring of compensated or decompensated cirrhosis and hepatocellular carcinoma are updated.

We report a case of West Nile virus (WNV) infection in a symptomatic woman living in Tuscany in 2007. A retrospective analysis on cerebrospinal fluids drawn from people affected by neurological ...diseases with unknown etiology allowed the identification of a case of WNV infection before the WNV outbreak in the Northeast Italy in 2008. This emphasizes the importance of maintaining a high level of epidemiological surveillance all over the Italian territory.
A survey of 107 patients continuously treated for more than 12 months with a Cimicifuga racemosa rhizome (black cohosh) herbal extract was recently conducted by Firenzuoli et al to verify its ...possible hepatotoxic effects.1 The paper concluded that, despite the alert released on July 2006 by the European Medicines Agency (EMEA) and the Committee on Herbal Medicinal Products (HMPC), C racemosa rhizome herbal extract should be considered safe with regard to liver toxicity.
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.

In August, 1997, a woman with no history of travel to malarious regions developed
Plasmodium vivax malaria. She lived in a rural area of Italy where indigenous
Anophyles labranchiae mosquitoes were ...present.
An environmental investigation was done within a 3 km radius of the patient's house. Adult mosquitoes and larvae were collected and examined by PCR with the gene for plasmodium circumsporozoite protein as target. About 200 people living in the area were interviewed to detect possible carriers of
P vivax.
None of the mosquitoes captured were carrying any malarial organisms. The house-to-house investigation identified a 7-year-old girl who had had a feverish illness a few days after her arrival in Italy from India, and who, 3 months later, still had
P vivax in her blood; she and her mother had antimalarial antibodies.
These investigations suggest that the index case of malaria was caused by local anopheline mosquitoes infected with exogenous
P vivax.
