The methylation and transsulfuration pathways are intimately linked and have been implicated in the progression of neurologic damage and immune cell depletion caused by human immunodeficiency virus (HIV) infection. We studied the following metabolites related to these pathways: S-adenosylmethionine (SAMe), homocysteine, cysteine, cysteinyl-glycine, and(More)
An involvement of calcitonin in the mechanism of pain perception has recently been hypothesized. In order to collect information about the relationship between this hormone and well known analgesic substances such as opioids, we have studied the serum levels of calcitonin in a group of heroin addicts, finding higher average concentrations than in normal(More)
In a study of 497 injection drug users who had isolated presence of antibody to hepatitis B core antigen (anti-HBc) at the time of enrollment, 404 (81%) retained this condition after a mean of 49 months of follow-up, during which time no new hepatitis B surface antigen marker was detected. These findings support the hypothesis that patients with isolated(More)
BACKGROUND In Italy, about 5% of the population is represented by immigrants. The epidemiology of hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infection in Africa is very different from Europe; the present study aimed to assess the seroprevalence of viral hepatitis infections in sub-Saharan African immigrants living in(More)
A nested polymerase chain reaction (PCR) was evaluated for the detection of cytomegalovirus (CMV) DNA in cerebrospinal fluid (CSF). CSF and serum samples from 19 AIDS patients with intracerebral CMV infection diagnosed at autopsy were retrospectively examined. As controls, CSF and serum samples from 15 AIDS patients with only extracerebral CMV involvement(More)
