Immune responses to specific antigens can be influenced by an individual's genetic make-up. We examined whether the efficacy of a vaginal mucosal vaccine for urinary tract infections (UTI) was affected by a patient's human leucocyte antigen (HLA) phenotype. Urinary tract infection data and the HLA phenotypes of 47 women participating in a phase II clinical trial of immunization for recurrent UTI were statistically analysed for associations between HLA-A, -B, -DR, or -DQ phenotype and postimmunization infection course. Women who received the vaccine and had HLA-DR phenotypes other than DR2 had significantly delayed times to re-infection compared with women receiving placebo. Vaccine-treated patients with the HLA-DR2 phenotype had re-infection courses that were not different than women receiving placebo. These results indicate that the efficacy of a vaginal mucosal UTI vaccine may be influenced by an individual's HLA-DR phenotype.
A total of 805 positive blood cultures obtained over a 4-month period during 1997 by the AccuMed ESP-384 system were evaluated and compared with 471 positive blood cultures obtained during 1989. Of the 805 microorganisms isolated in 5-day culture and testing by the ESP-384, 671 (83.4%) were detected within the first 2 days and 758 (94.2%) within 3 days. There were 47 (5.7%) microorganisms detected in culture Days 4 and 5 from 42 patients and review of the medical records from these patients demonstrated that no significant changes in clinical management were instituted as a result of detection and identification of these isolates. These 47 organisms were considered to be zero to equivocal clinical relevance. These data suggest that a 3-day routine blood culture incubation protocol with the ESP-384 system may be sufficient when considering detection rate, clinical relevance, and cost-effectiveness. The microbial spectrum and relative frequencies in this study were found to be similar to those of positive blood cultures obtained during 1989.
There are many different rheumatic symptoms of gastrointestinal (GI) disorders and a whole range of GI symptoms that occur in rheumatologic disorders. Spondyloarthropathies (SpA) are closely related to the GI tract. Bacterial DNA has been detected in peripheral but not the sacroiliac joints of patients, including enterobacteria; the significance of this finding is not clear yet because antibiotic therapy seems not to be effective. The synovial lymphocyte proliferation of reactive arthritis (ReA) patients to the 60-kD heat-shock protein of Yersinia plays a major role in the immune response. Anti-Klebsiella antibodies are associated with gut lesions in SpA; their significance for the pathogenesis of SpA remains uncertain. ReA patients seem to have an impaired TH1-cytokine response, which might contribute to disease persistence. HLA B27-positive subjects seem to have a low tumor necrosis factor-alpha secretor status, possibly leading to diminished immune responses against certain microbes. In patients with Whipple's disease, Tropheryma whippelii can be cultured from gut biopsy specimens when interleukin-4 is added. The gene for hemochromatosis has been identified. Hepatitis C virus DNA can be found in many patients with cryoglobulinemia. Treatment with interferon-alpha might help in some patients. Effective treatment for primary biliary cirrhosis with ursodeoxycholic acid is not helpful for rheumatic symptoms. The severity of esophageal dysfunction in systemic sclerosis does not correlate with symptoms. GI symptoms do, although not frequently, occur in vasculitides.
