Background Fibromyalgia Syndrome (FS) is a chronic condition with widespread pain. Increased FS prevalence was observed in patients with Diabetes Mellitus (DM) in several of former studies.1,2
Objectives The aim of this study is to assess the frequency of FS in patients with Type 2 DM. Additionally; we aimed to evaluate the association of pain severity with disease control of DM.
Methods Patients with Type 2 DM who were followed in Endocrinology Clinic of Cukurova University Hospital were included in the study. FS was diagnosed according to 2013 Alternative Criteria set by American College of Rheumatology. Patients with anemia, hyper- and hypothyroidism, malignancy, pregnancy and rheumatologic conditions were excluded. Patients' pain during morning and sleep was evaluated by Visual Analog Scale (VAS). Fasting blood glucose and Hba1c levels were measured to assess disease control of DM.
Results Ninety-two patients (61 female, 31 male) with Type 2 DM were included in the study. Mean age of the patients was 57.84 ± 10.01 years. FS was diagnosed in 4.3% of the patients. No significant difference was observed between Hba1c levels of Type 2 DM patients with and without FS (P=0.87). Mean VAS scores of the patients during morning and sleep were detected as 2.97±2.96 and 2.51±2.73 respectively. There was a weak negative correlation between VAS morning scores and Hba1c levels in diabetic patients (r=-0.24, P=0.04). There were no correlations of VAS sleep scores with fasting glucose and Hba1c levels (P=0.54, P=0.34 respectively).
Conclusions According to the results of the present study, when diagnosis is based on 2013 alternative criteria of ACR, FS frequency in patients with Type 2 DM is found to be similar to that of among healthy populations. Yet, better control of blood glucose levels might decrease daily pain in diabetic patients.
