Evidence for the presence of autochthonous (locally acquired) cases of acute hepatitis E virus infections in Italy since the 80s.

BACKGROUND: Autochthonous (locally acquired) cases of acute hepatitis E virus have been recently reported in several developed countries. AIM: To evidence cases, if any, and characteristics of acute hepatitis E virus infections in North-East of Italy several years ago. METHODS: In 2014, stored sera of 165 nonA-nonB acute hepatitis referred to the hospital of Padua during the period 1978-1991 were tested for hepatitis C virus antibodies by EIA III and for anti-hepatitis E virus IgM by Wantai HEV IgM ELISA. Anti-hepatitis E virus IgM positive sera were tested by Real Star HEV RT-PCR kit (Altona Diagnostics, Hamburg, Germany). RESULTS: Ninety-six (58.1%) sera resulted anti-HCV positive, and thus classified as acute C hepatitis. None of these subjects was anti-HEV IgM positive. Out of the 69 anti-HCV negative cases, 4 (5.8%) resulted anti-HEV IgM positive (one case hepatitis E virus-RNA positive), with an increasing trend from 2.8% during the years 1978-1984 to 9.1% during the years 1985-1991. All cases occurred in Italian patients with no travel abroad history. CONCLUSIONS: There is evidence for the presence of autochthonous cases of acute hepatitis E virus infections in Italy since 80s.

Spectral domain optical coherence tomography imaging of tubercular chorioretinitis and intraretinal granuloma. Intraretinal tuberculosis: a case report.

The aim of this study is to report the clinical and spectral domain optical coherence tomography (SD-OCT) findings in a patient suffering from ulcerative colitis with bilateral tubercular chorioretinitis and intraretinal granuloma regressed with systemic antitubercular therapy (ATT). This study is a case report of a 33-year-old Bangladeshi male with ulcerative colitis treated with oral corticosteroids and azathioprine who was referred to our department with a diagnosis of central serous chorioretinopathy. Serological tests, the Mantoux skin test, complete ophthalmologic examination, ocular fundus photography, fundus fluorescein angiography, and SD-OCT scans were performed. The ophthalmological inflammatory pattern and serological investigations provided an early diagnosis of ocular tuberculosis. Systemic ATT led to significant improvement and resolution of the ocular inflammation. SD-OCT was a useful non-contact imaging technique in the follow-up of tubercular choroiditis. The excellent response to systemic ATT confirmed the clinical diagnosis. This is an unusual case of tubercular chorioretinitis with intraretinal granuloma and is the first such SD-OCT description reported in the ophthalmological literature.
