BACKGROUND A few recent studies have suggested that other sexually transmitted infections may increase the likelihood of a human papillomavirus (HPV) infection progressing to high-grade cervical neoplasia and cancer. GOAL The goal was to assess whether exposures to Chlamydia trachomatis, human T-cell lymphotrophic virus type 1 (HTLV-I), and/or human(More)
OBJECTIVE We investigated changes in hematologic and biochemical parameters associated with human T lymphotropic virus type 1 (HTLV-1) infection, antibody titer, and provirus load. Additionally, on a subset of participants, we assessed the epidemiologic relationship of HTLV-1 with Strongyloides stercoralis. METHODS Among volunteer blood donors in Jamaica,(More)
BACKGROUND Infection by Helicobacter pylori is often acquired during childhood. Recent studies suggest that inflammatory cytokines may play a role in susceptibility to, and disease phenotype caused by, H. pylori infection, but the association of host genetic variability with risk of H. pylori infection has not been studied in children. METHODS We(More)
The natural history of human T-lymphotropic virus type I (HTLV-I) has been shown to differ markedly by geographic area. The differences include contrasting patterns of risk of adult T-cell lymphoma (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP), which may be due in part to differences in host immune response to infection. To(More)
To characterize a host polygenic profile associated with susceptibility to human T lymphotropic virus type I (HTLV-I) infection, we examined common variants in 11 immune-related genes among Jamaican children born to HTLV-I-seropositive mothers. Compared with HTLV-I seronegatives, haplotypes of IL6 (-660G/-635C/-236G) and IL10 (-6653C/-1116G) were(More)
