Helicobacter pylori seropositivity is associated with antinuclear antibodies in US adults, NHANES 1999-2000.

ABSTRACT: Infectious diseases, such as Helicobacter pylori, which produce systemic inflammation may be one key factor in the onset of autoimmunity. The association between H. pylori and antinuclear antibodies (ANA), a marker of autoimmunity, has been understudied. Data from the 1999-2000 National Health and Nutrition Examination Survey were used to evaluate the cross-sectional association between H. pylori seroprevalence and ANA positivity in US adults aged ?20 years. ANA was measured in a 1:80 dilution of sera by indirect immunofluorescence using HEp-2 cells (positive ?3). H. pylori immunoglobulin G enzyme-linked immunosorbent assays were used to categorise individuals as seropositive or seronegative. H. pylori seropositivity and ANA positivity were common in the adult US population, with estimated prevalences of 33.3% and 9.9%, respectively. Both were associated with increasing age. H. pylori seropositivity was associated with higher odds of ANA (prevalence odds ratio = 1.89, 95% confidence interval = 1.08-3.33), adjusted for age, sex, race/ethnicity, educational attainment and body mass index. H. pylori infection may be one key factor in the loss of self-tolerance, contributing to immune dysfunction.

Project description:BACKGROUND:Clinical reports link specific medications with the development of antinuclear antibodies (ANA), but population-based evidence is limited. OBJECTIVE:The present study investigated associations between prescription medication use and ANA in a representative sample of the adult noninstitutionalized US population, first focusing on medications previously related to ANA and then considering all medications reported in the National Health and Nutrition Examination Survey (NHANES). METHODS:Based on NHANES data (1999-2004) for 3608 adults (ages ?18 years), we estimated odds ratios (ORs) and 95% confidence intervals (CIs) to assess associations between recent medication use and ANA (overall and in sex and age subgroups), adjusted for potential confounders and the survey sampling design. RESULTS:We found no evidence that most medications previously associated with ANA in specific individuals were risk factors for ANA in the general population, although statistical power was limited for some medications. Overall, ANA were less prevalent in adults who recently used any prescription medications compared with those who did not (OR?=?0.73; CI?=?0.57,0.93), and likewise several classes of medications were inversely associated with ANA, including hormones (OR?=?0.73; CI?=?0.55,0.98), thiazide diuretics (OR?=?0.43; CI?=?0.24,0.79), sulfonylureas (OR?=?0.41; CI?=?0.19,0.89), and selective serotonin reuptake inhibitor antidepressants (OR?=?0.65; CI?=?0.42,0.98). Positive associations with ANA were seen for loop diuretics (OR?=?1.72; CI?=?1.03,2.88) in all adults, and for benzodiazepines (OR?=?2.11; CI?=?1.09,4.10) and bronchodilators (OR?=?1.83; CI?=?1.00,3.38) in older (ages ?60) adults. Estrogens were positively associated with ANA in older women (OR?=?1.80; CI?=?1.00,3.23) but inversely associated with ANA in younger (ages 18-59) women (OR?=?0.43; CI?=?0.20,0.93). Regarding individual medications, ANA were positively associated with ciprofloxacin (OR?=?4.23; CI?=?1.21,14.8), furosemide (OR?=?1.79; CI?=?1.09,2.93), and omeprazole (OR?=?2.05; CI?=?1.03,4.10) in all adults, and with salmeterol (OR?=?3.76; CI?=?1.66,8.52), tolterodine (OR?=?6.64; CI?=?1.45,30.5), and triamterene (OR?=?3.10; CI?=?1.08,8.88) in older adults. Also, in younger adults, hydrochlorothiazide was inversely associated with ANA (OR?=?0.44; CI?=?0.20,0.98). CONCLUSIONS:Our findings in the general population do not confirm most clinically reported positive associations between specific medications and ANA in some individuals. However, novel positive ANA associations with other medications, as well as unexplained inverse associations with certain classes of medications and overall medication use, deserve further research to clarify the possible roles of medications as risk and protective factors in the development of autoantibodies and autoimmune disease.
