Background: Several studies have suggested that Helicobacter pylori (H. pylori) infection is a risk factor for colorectal cancer (CRC), while others have not confirmed this hypothesis. This work aimed to assess the relation of CRC with H. pylori seropositivity and with seropositivity to 16 H. pylori proteins, in the MultiCase-Control study, MCC-Spain. Methods: MCC-Spain is a multicase-control s...
background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...
OBJECTIVE We conducted a large-scale cross-sectional study to assess the prevalence of Chlamydia pneumoniae and clarify the association between seropositivity and risk factors, such as smoking status, physical activity and body mass index in Japanese rural districts. METHODS A total of 1,063 men and 1,573 women aged 18-94 years participated in 1999. Serum index values (ID) of IgA and IgG anti...
We report the HIV seropositivity among adult TB patients from our hospital, a tertiary care hospital in north India between 2000-2002. Of the 555 patients with various forms of tuberculosis, 52 were found to be seropositive (9.4%). In 1994-1999, the HIV seropositivity in this hospital was only 0.4 per cent (2 of 500 patients). This communication describes a dramatic increase in seropositivity a...
Getah virus (GETV), which is transmitted by mosquitoes, causes lower limb edema and stiffness in horses. In this study, we investigated the sero-surveillance of GETV among Thoroughbred racehorses in Korea during 2013 and 2014. A total of 1,182 equine serum samples collected from Thoroughbred racehorses in four provinces (Gyeongnam, Gyeonggi, Jeonbuk and Jeju provinces) were analyzed using virus...
Because Helicobacter pylori colonization can produce systemic as well as local effects, it may be associated with carcinogenesis in extra gastric target organs. The currently available data regarding a possible link between H. pylori seropositivity and colorectal cancer risk are limited and inconclusive. In this prospective case-control study nested within the Alpha-Tocopherol, Beta-Carotene St...
BACKGROUND Infection with cytomegalovirus (CMV) is considered a risk factor for progression of atherosclerotic disease. Patients with end-stage renal disease (ESRD) display signs of frequent CMV re-activation, which may be caused by the uraemia-associated defect in cellular immunity. The possible contribution of CMV seropositivity to the hugely increased risk for cardiovascular disease in patie...
Objective: To determine whether exposure to tobacco smoke is associated with double stranded DNA (dsDNA) seropositivity in patients with systemic lupus erythematosus (SLE). Methods: Medical record review was used to confirm the diagnosis of SLE and evaluate dsDNA antibody status. Smoking status at the time of autoantibody testing was assessed by patients’ questionnaire responses. Multivariate r...
Polyomaviruses (PyV) are potentially tumorigenic in humans. However, limited data exist on the population seroprevalence of PyVs and individual characteristics that relate to seropositivity. Using multiplex serology, we determined the seroprevalence of 10 human PyVs (BK, JC, KI, WU, MCV, HPyV6, HPyV7, TSV, HPyV9, and HPyV10) among controls from a population-based skin cancer case-control study ...
PURPOSE To investigate an association between Helicobacter pylori seropositivity and HLA-B27-positive acute anterior uveitis (AAU) in Korean patients. METHODS Retrospective analysis was performed with data from 106 patients previously diagnosed with AAU without clinical evidence of spondyloarthropathy. Serum immunoglobulin G antibodies to H. pylori were measured by enzyme-linked immunosorbent...
