Hepatitis C virus serotypes and sources of infection in HCV-positive patients from a restricted geographical area were evaluated. HCV serotypes were determined by Murex serotyping assay. Of 192 samples, serotypes were detected in 189 (98.5%): type 1 proved to be the most common (53.1%), followed by types 2 (15.2%), 3 (6.2%), 6 (5.3%), 4 (3.6%) and 5 (1.6%).(More)
Post-zygotic activating mutations in PIK3CA and other genes encoding members of PI3K-AKT-mTOR pathway have been found in various overgrowth syndromes that have been grouped together as PIK3CA-related overgrowth spectrum (PROS). We report a female patient with gait disturbance, leg pain, isolated macrodactyly of the foot, and mild intellectual disability.(More)
We investigated the relation between the presence of IgM antibodies to hepatitis C virus (HCV) and serotypes of HCV, in particular when a high level of IgM antibodies are present in patients infected with HCV serotype I and may be associated with the source, duration and evolution of infection. The study involved two anti-HCV positive groups with chronic(More)
Hepatitis C virus serotypes and the duration of infection HCV positive subjects from a restricted geographical area in Italy, were evaluated. HCV serotypes were determined by Murex serotyping assay. Serotypes were detected in 592 (88.0%) of 669 samples. Type 1 proved to be the most frequent (48.9%), followed by types 2 (29%), 3(4.5%) and 4 (2.1%). The(More)
Hepatitis C virus (HCV) infection is highly prevalent in haemodialysis patients. To date, only a few studies involving a small number of subjects have characterized HCV-infected dialysis patients by serotyping. The spread of HCV serotypes in 114 HCV-positive dialysis patients from the same geographical area was evaluated by Murex HCV serotyping assay.(More)
In order to evaluate hepatitis C virus-RNA (HCV-RNA), immunoglobulin M (IgM) anti-HCV and risk factors in haemodialysis patients, 180 subjects (45 HCV negative and 135 HCV positive) were studied. Sex, age, duration of dialysis, number of transfusions and ALT were also considered. HCV-RNA was determined by the Amplicor HCV test, and IgM anti-HCV by the(More)
