Highlights


•
MDS cases were significantly more likely to have a previous diagnosis of autoimmune disease when compared with controls.

•
Previous diagnosis with autoimmune disease did not impact overall survival following an MDS diagnosis.

•
MDS cases were also more likely to report coronary heart disease and chronic fatigue syndrome than controls.



Abstract
Background
Autoimmune diseases and hematopoietic malignancies are known to cluster within individuals, suggesting intertwined etiologies. A limited number of studies have evaluated pre-existing medical conditions as risk factors for myelodysplastic syndromes (MDS). We evaluated associations between autoimmune disease and other medical conditions and risk of MDS.

Methods
Cases were identified through the Minnesota Cancer Reporting System. Controls were identified through the Minnesota State driver’s license/identification card list. History of autoimmune disease and other medical conditions was based on self-report; proxy interviews were not conducted. Unconditional logistic regression was used to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CI).

Results
We included 395 cases and 694 controls. Cases were significantly more likely to report a diagnosis of any autoimmune disease when compared with controls (aOR=1.41, 95% CI: 1.05–1.89) after adjustment for age, sex, education, NSAID use, exposure to benzene and body mass index. When we evaluated specific autoimmune conditions, a statistically significant association was observed for hypothyroidism (aOR=2.16, 95% CI: 1.39–3.34) and odds ratios were elevated for inflammatory bowel disease (aOR=1.75) and systemic lupus erythematosus (SLE; aOR=3.65), although these associations did not reach statistical significance. Presence of an autoimmune condition did not impact overall survival (p = 0.91).

Conclusion
Our results validate previous findings of an association between autoimmune disease and MDS. Further studies are required to determine whether this association is due to shared etiology, treatment for autoimmune diseases, or altered immune surveillance or bone marrow damage caused by the autoimmune condition.

Seems more like early misdiagnoses. Which are clearly very common. It would be great if medical specialties actually cared about "their patients" being misdiagnosed. It's not going to improve by magic, though. Or by doing more of the thing that leads to massive systemic misdiagnosis, as this particular problem is often presented as the solution to the problem. Somehow.

Or nothing could be done about it. As is tradition. Waiting until problems get worse is another way to do things. Not a good one, but it is one.
