Factors Associated with Fibromyalgia Syndrome in Peritoneal Dialysis Patients.

Purpose: We evaluated the prevalence of fibromyalgia syndrome (FMS) in peritoneal dialysis (PD) patients and whether this syndrome is associated with gender, age, duration of PD, or other laboratory parameters.

Methods

A total of 60 chronic PD patients (26 women, 34 men) and 60 healthy controls (30 women, 30 men) were included. We recorded each participant's age, gender, cause of kidney failure, PD duration, laboratory parameters, education level, and symptoms related to FMS, diagnosed according to the 2010 American College of Rheumatology criteria.

Results

Eleven patients (18%) in the PD group and nine (15%) in the control group met the diagnostic criteria for FMS. There were no statistically significant differences in age; gender; education level; PD duration; laboratory parameters; or sleepdisturbance, fatigue, or cognitive symptoms between the FMS and non-FMS groups among the PD patients. We next compared control and PD patients with FMS. Both groups were of a similar age and gender and had similar sleep disturbance and cognitive symptoms, but more patients had fatigue in the control group.

Conclusions

The prevalence of FMS among PD patients was similar to that in the general population, and FMS was not associated with gender, age, duration of PD, or other laboratory parameters.
