Dr Toufic Kabbani and colleagues from Massachusetts, USA investigated whether risk for non–insulin-dependent diabetes mellitus (NIDDM) and metabolic syndrome are affected by celiac disease.
The research team examined the prevalence of NIDDM and metabolic syndrome among adults with celiac disease, compared with matched controls.
The team assessed medical records of 840 patients with biopsy-proven celiac disease for diagnoses of NIDDM, hypertension, or hyperlipidemia, body mass index (BMI), lipid profile, and levels of glucose or glycosylated hemoglobin, to identify those with metabolic syndrome.
Patients without celiac disease were matched for age, sex, and ethnicity.
|Mean BMI of patients with celiac disease was lower than that of controls|
The prevalence of NIDDM and metabolic syndrome in the celiac disease cohort was compared with that of the controls and subjects included in the National Health and Nutrition Examination Survey.
The researchers found that 3% of patients with celiac disease had NIDDM compared with 10% of controls.
Similarly, the prevalence of metabolic syndrome was significantly lower among patients with celiac disease than controls.
The team observed that the mean BMI of patients with celiac disease was significantly lower than that of controls.
However, celiac disease was still associated with a lower risk of NIDDM, after controlling for BMI.
Dr Kabbani's team concludes, "The prevalence of NIDDM and metabolic syndrome are lower among patients with celiac disease than in matched controls and the general population."
"These differences are not explained by differences in BMI."
"Studies are needed to determine the mechanisms by which celiac disease affects the risk for NIDDM and metabolic syndrome."
