Hepatitis B virus reactivation after effective sofosbuvir and ribavirin treatment in a patient with occult hepatitis B virus infection.

Reactivation of the hepatitis B virus (HBV) has been reported in patients with occult infection (OBI), i.e. HBV surface antigen (HBsAg) negative, HBV core antibody (anti-HBc) positive ± antibodies against HBsAg (anti-HBs) and detectable HBV DNA in serum or liver, receiving immunosuppressive or cytotoxic therapies. Recently, concerns have been raised regarding the risk of HBV reactivation in OBI patients treated with direct acting antiviral agents (DAAs) for chronic hepatitis C (CHC). Here we describe a case of HBV reactivation in a 72-year-old woman with OBI as a possible consequence of effective treatment with sofosbuvir (SOF) and ribavirin (Rbv) for genotype 2a/2c CHC.

Measles, rubella, mumps and chicken pox are highly contagious viral infectious diseases that may cause potentially serious complications, in particular in immunocompromised patients, newborns and pregnant women. In Italy, vaccine coverage remains sub-optimal and outbreaks continue to occur with heavy impact on public health. Immunization is one of the most beneficial available public health measures to prevent serious illness, severe complications, disabling sequelae and deaths. Attenuated live virus vaccines have been commercially available since the '90s and their efficacy, safety and favourable cost-benefit ratio have been extensively documented.

Trigger-oriented HIV testing at Internal Medicine hospital Departments in Northern Italy: an observational study (Fo.C.S. Study).

BACKGROUND: Early detection of undiagnosed HIV infected patients is of paramount importance. The attitude of Italian hospital-based Internal Medicine physicians to prescribe HIV testing following the detection of HIV-associated signs, symptoms and behaviours (triggers) has been reported to be poor. The aim of the study is to quantify the extent of the missed opportunities for early HIV diagnosis in Internal Medicine Departments (IMD). METHODS: Patients admitted to IMD of a General University Hospital in Italy in March-June 2013 were interviewed using a structured questionnaire investigating the presence of triggers for HIV testing, including patient's characteristics, symptoms and conditions associated with HIV infection. HIV tests performed during hospitalisation were recorded. RESULTS: HIV testing was performed in 73 (6.6%) out of 1113 hospitalisations (1072 patients), providing positive results in three cases (4.1%). All of them presented ≥1 triggers. Conversely, 853 triggers were identified in 528 hospitalisations with at least one trigger (47.4%). The proportion of hospitalisations where an HIV testing was prescribed was 3.1%, 9.5% and 16.0% in the presence of zero, one-to-two or more triggers, respectively. Age <70 years, female gender, length of hospital stay, haematological disease, HBV infection, multiple sexual partners and lymphadenopathy were predictors of HIV testing by logistic regression analysis. CONCLUSIONS: Although chances of an HIV test being performed in patients hospitalised in IMD increases along with the number of triggers, the number of tests being performed in people presenting with triggers is unacceptably low and requires educational interventions in order to obtain individual and public health advantages.

Chlamydia trachomatis conjunctivitis in a male teenager: a case report.

An 18 year old man was seen at a Sexually Transmitted Infections (STIs) clinic for counselling and treatment of Chlamydia trachomatis genital infection which had been diagnosed during a screening survey of high school students. For two months he had reported conjunctival hyperaemia, increased tearing, itching, and mucopurulent secretions, predominantly on the left eye. His ophthalmologist had made a diagnosis of follicular conjunctivitis and lower superficial punctate keratitis (left eye more than right eye), irresponsive to topical treatment. Chlamydial conjunctivitis was suspected and confirmed by a positive nucleic acid amplification test (NAAT) performed on conjunctival scraping. The patient was treated with azithromycin 1 g single dose orally and tetracycline/betamethasone eye ointment for one month. A complete resolution of symptoms was observed three months after aetiological treatment. This case highlights the need to include C. trachomatis infection in the differential diagnosis of acute or chronic follicular conjunctivitis among sexually active young individuals.
