Evaluating Liver Fibrosis by Transient Elastometry in Patients With HIV-HCV Coinfection and Monoinfection.

BACKGROUND: Due to the high efficacy of combination antiretroviral therapy (cART), the number of patients living with HIV is increasing. Chronic HCV infection has become a leading cause of non-AIDS related morbidity and mortality in patients with HIV infection. OBJECTIVES: The aim of this cross-sectional study was to identify factors associated with liver fibrosis (LF) in patients with HIV monoinfection and HIV-HCV coinfection. PATIENTS AND METHODS: We analyzed LF by transient elastometry ([TE], Fibroscan) in three groups of patients (HIV, HIV-HCV and HCV) followed at the Infectious Diseases Department of University of Ancona, Italy, between October 2009 and November 2012. RESULTS: In total, 354 adults including 98 HIV, 70 HIV-HCV and 186 HCV patients were studied. HIV-HCV patients had a longer duration of HIV (P < 0.006) and HCV (P < 0.001) infections. Additionally, they were receiving cART therapy for a longer period (P < 0.001); they had higher prevalence of lipodystrophy (P < 0.001) and higher HCV load (P = 0.004). LF was significantly more pronounced in HCV and HIV-HCV compared to HIV patients (P < 0.001). A total of 13.3%, 39.2% and 51.4% of HIV, HCV and HIV-HCV, respectively, showed a LF ≥ F2. Additionally, a severe LF (F = 4) was significantly more frequent among HIV-HCV compared to other groups. A longer exposure to didanosine, stavudine, lopinavir/ritonavir and fosamprenavir resulted in increased LF by univariate analysis (P ranging from < 0.001 to 0.007). By logistic regression analysis, the only variables significantly associated with increased LF were HCV coinfection, older age, and high AST values (P ranging from < 0.001 to 0.036). CONCLUSIONS: HCV coinfection, older age and AST were associated with LF in patients with HIV infection.

Comparison of liver fibrosis progression in HIV/HCV co-infected and HCV mono-infected patients by transient elastometry.

Monitoring of liver fibrosis (LF) is an essential tool for preventing liver-related complications in HIV/HCV co-infected patients. In this study, we compared LF progression by transient elastometry (TE) in 50 HIV/HCV co-infected and 115 HCV mono-infected patients followed in our institution between June 2006 and December 2011. Patients naive to interferon therapy and with at least two measurements of liver stiffness by TE were included. In all, 76% of HIV/HCV co-infected and 75% of HCV mono-infected patients remained in the same stage of LF over time. Conversely, 19% and 15% of HIV/HCV co-infected and HCV mono-infected subjects, respectively, had progression to advanced LF (≥ F3). Our study found a similar proportion of HIV/HCV co-infected and HCV mono-infected patients that developed an advanced LF during the follow-up time considered. Alcohol abuse was the only factor significantly associated with the progression as evidenced by multiple quantile regression analysis.

Cognitive-motor profile, clinical characteristics and diagnosis of CHARGE syndrome: an Italian experience.

Since 2005, the Pediatric Clinic of Maternal-Infantile Sciences Institute in Ancona, in collaboration with the Lega del Filo d'Oro in Osimo, has been taking care of 35 patients with clinical and molecular diagnosis of CHARGE syndrome. Our investigation is the largest Italian cohort study of CHARGE patients. CHARGE syndrome is a multiple malformation syndrome involving ocular coloboma, heart defects, choanal atresia, retardation of growth and\or development, genital anomalies and\or urinary and ear abnormalities which leads to visual-auditory disabilities, cognitive impairment and behavioral abnormalities. Our purpose is to expand the knowledge of this syndrome by reviewing this group of affected patients in order to delineate in detail the natural history of the disease, and in particular to define the cognitive and motor profiles using an Italian questionnaire called "Progress Guide". Our main results show that Italian CHARGE patients have more delayed development in their physical abilities or skills with respect to normal patients. In particular, the delay is statistically significant in regard to self-care skills (worse toileting, better washing) and the communication skill (language). On the other hand, the expressive skills are still preserved. When patients are considered according to their age (≤3 years) and (>3 years), the older ones have more delayed development than the younger ones when compared with healthy individuals of the same age.

Role of small intestinal bacterial overgrowth and Helicobacter pylori infection in chronic spontaneous urticaria: a prospective analysis.

The aim of this study is to assess the associations between chronic spontaneous urticaria (CSU), Helicobacter pylori infection and small intestinal bacterial overgrowth. Forty- eight patients with CSU were studied by scoring the urticaria activity and assesing the quality of life. Patients with H. pylori infection (n=11) or small intestinal bacterial overgrowth (n=13) were specifically treated for one week and clinically evaluated both before and 4 weeks after the eradication therapy. Eradication of H. pylori infection led to a significant improvement in CSU (p<0.002). In contrast, eradication of small intestinal bacterial overgrowth was not associated with any clinical improvement in CSU, despite the fact that these patients had statistically significant more urticaria activity at baseline. Thus there is no evidence to support the eradication of small intestinal bacterial overgrowth in CSU, but eradication of H. pylori infection may result in an improvement of the disease.
