ABO and Rh blood group distribution in ANA positive patients
Aims: Antinuclear antibody (ANA) positivity is a common finding in various autoimmune diseases, particularly those of rheumatologic origin. While ANA positivity alone may not be diagnostic, it serves as a valuable marker when supported by clinical findings, aiding in the diagnosis and prediction of autoimmune diseases. The relationship between blood group systems and various diseases has been an area of interest in medical research. In this study, we aimed to investigate the potential association between ABO blood group and ANA positivity, specifically examining whether the ABO blood group status poses a risk for autoimmune diseases in individuals with rheumatologic conditions.
Methods: In this retrospective study, we analyzed the blood group data of 536 patients who tested positive for ANA and were receiving treatment for rheumatologic diseases. The blood group status of these individuals was determined using standard serologic techniques. The distribution of ABO and Rh factor blood groups among ANA-positive patients was compared with the blood group distribution in the general population. Statistical analysis was performed to assess any significant differences.
Results: The analysis revealed that the distribution of ABO and Rh factor blood groups among ANA-positive individuals did not show a statistically significant difference compared to the general population. Specifically, there was no significant deviation in the prevalence of ABO blood groups (A, B, AB, O) or Rh factor (positive or negative) among ANA-positive patients compared to expected frequencies based on population data.
Conclusion: Based on our findings, there appears to be no significant association between ABO blood group status and ANA positivity in patients with rheumatologic diseases. The distribution of ABO and Rh blood groups among ANA-positive individuals closely resembled that of the general population. Therefore, our study suggests that current blood group status may not serve as a predictive factor for autoimmune diseases in individuals who test positive for ANA. Further research is warranted to explore other potential factors contributing to autoimmune disease susceptibility.
