Hepatitis E virus co-infection in HIV-infected patients in Foggia and Naples in southern Italy.

BACKGROUND: Hepatitis E virus (HEV) infection represents an emerging infection in developed countries and is thought to be a zoonotic infection. It has recently been described as a new causative agent of acute and chronic hepatitis in immunosuppressed subjects, including HIV-infected patients. The aim of this study was to assess the sero-virological prevalence of HEV in HIV patients and in the general population as control group. METHODS: A prospective and observational cohort study was carried out in two hospitals in southern Italy. The seroprevalence of HEV was determined in a cohort of 959 subjects, 509 (53%) of whom were HIV-positive patients and 450 were from the general population. Serum samples were tested for anti-HEV antibodies; repeatedly positive results were confirmed by a Western blot assay. In positive patients HEV RNA and genotypes were also determined. RESULTS: A total of 46 (4.8%) of the 959 serum samples examined were reactive to anti-HEV Ig and confirmed by Western blotting. The prevalence of HEV antibodies (IgG and/or IgM) was 2.7% in the control group and 6.7% in HIV-infected patients. Anti-HEV IgM was found in 6/46 (13.0%) of the anti-HEV Ig-positive serum samples, in 5/34 HIV patients and in 1/12 of the general population. No HIV-infected patient presented chronic hepatitis with HEV infection alone. CONCLUSIONS: This study indicates a higher circulation of HEV in HIV-infected patients, whereas a low prevalence of HEV antibodies in the general Italian population was shown. Chronic hepatitis with HEV alone was absent, while it was present in subjects with HIV-HEV, co-infected with hepatitis B virus (HBV) and/or hepatitis C virus (HCV).

Evidence-based practice among nurses in Italy.

A cross-sectional survey was conducted among a random sample of 449 nurses in Italy, using a self-administered questionnaire to assess knowledge, attitudes, and behaviors regarding evidence-based practice (EBP). A significantly higher level of knowledge was observed among nurses who (a) did not work in medical and surgical wards; (b) believed that the evaluation of the efficacy of the health interventions is needed in their activity; (c) believed that the clinical experience must be combined with the evidence; (d) attended a course about EBP in the last year; and (e) received information from courses and scientific journals. The perceived importance of the application of guidelines and protocols was significantly higher among nurses who (a) worked in medical wards; (b) agreed that the guidelines are useful in identifying and selecting interventions; (c) believed that the evaluation of the efficacy of the health interventions is needed in their activity; (d) believed that the clinical experience must be combined with the evidence; (e) attended a course about EBP in the last year; and (f) received information from courses and scientific journals. Nurses were more likely to have modified their practice in the last year if they attended a course about EBP in the last year and if they often/always read scientific journals and guidelines. While these data were cross-sectional and the response rate was only 49%, the results suggest that continuing education programs are needed for improving nurses' knowledge and practice of EBP among nurses in Italy.

[Analysis of services and standards commitment charters in hospitals in the Campania Region (Italy)]. / Analisi delle carte dei servizi prodotte nelle aziende ospedaliere della regione Campania.

The healthcare services and standards commitment charter is a document produced by local health authorities/hospitals in Italy and aimed at citizens/healthcare users. With this document hospitals aim to openly express their philosophy and state which services they will commit to offer to users. In this study, services commitment charters of eight hospitals in the Campania Region were evaluated to assess contents and the ease of obtaining a copy of the document. The online versions of the document were available and updated for all hospitals while the printed versions could be found only in three. With regard to the relative legislation's highly innovative contents concerning the safeguard of patients-citizens, however, study results revealed notable shortcomings with respect to all parameters analysed, in all charters.

Virological and clinical aspects of HBV-HCV coinfection in HIV positive patients.

In a long-term follow-up study the clinical and virological presentation of HBV/HCV coinfection in anti-HIV positive patients was evaluated. Plasma HBV-DNA, HCV-RNA, and HIV-RNA were determined by PCR in 5 HBsAg/anti-HCV/anti-HIV positive patients, in 4 HBsAg/anti-HIV positive patients and in 82 anti-HCV/anti-HIV positive patients first observed at a Unit of Infectious Diseases in Naples (Italy) from 1990 to 2000 (follow up 6-16 years). All five hepatitis B and C coinfected patients showed reciprocal inhibition of viral replication on admission and during the follow up. At the end of the follow up a clearance of HBsAg from serum was observed in four patients and a clearance of anti-HCV in one of them. In two patients after clearance of HBsAg, evidence of occult HBV infection was observed, at times associated with a hepatic flare. None of the four patients with HIV/HBV coinfection lost HBsAg and none of the 82 with HIV/HCV coinfection lost anti-HCV during the follow up. In anti-HIV positive patients HBV/HCV coinfection is characterized by reciprocal inhibition of viral replication, more evident in HBV expression in plasma and at times by progression to occult HBV infection.

HPV oral infection. Case report of an HIV-positive Nigerian sex worker.

HPV infections have become a major problem in immunocompromised patients, particularly in HIV-positive subjects. HPV lesions are observed more frequently in the ano-genital area and rarely in different body areas, such as the skin and oral cavity. However, in HIV-positive subjects there is an increased risk of oral condylomas. We describe the case of an HIV-positive Nigerian young woman, who came to our notice due to the appearance of small labial and mouth mucous membrane lesions, related to HPV infection, as shown by a biopsy. These lesions were not evident in the genital area. After two years in which the patient no longer received therapy, there was a progressive reduction in CD4 count, associated with the development of the oral condylomas. Hence the patient began a new HAART combination, but after seven months, although a slight improvement emerged in the CD4 count with the disappearance of HIV-RNA, there has been no regression of oral condylomas.
