Investigation of the effect of fibromyalgia frequency on quality of life, daily living activities, disease perception, and clinical parameters in patients with chronic kidney failure undergoing dialysis treatment
Aims: Fibromyalgia syndrome (FMS) may be under-recognized in hemodialysis populations, where chronic inflammation, musculoskeletal complaints, and reduced health-related quality of life (HRQoL) frequently overlap. This study evaluated the prevalence of FMS in hemodialysis and examined its associations with pain, activities of daily living, HRQoL, and routine dialysis/laboratory parameters.
Methods: In this cross-sectional study, 127 adults were analyzed: 69 patients receiving maintenance hemodialysis (dialysis group) and 58 non-dialysis patients with FMS diagnosed using the ACR 2011 criteria and the 2016 revision (FMS group). Within the dialysis cohort, participants were stratified as FMS(+) (n=38) and FMS(–) (n=31). Pain intensity was assessed using a 0–10 Visual Analog Scale (VAS), functional independence with Katz Activities of Daily Living (ADL), and HRQoL with SF-36 (domain scores and summary measures). Dialysis/laboratory variables included pre- and post-dialysis blood urea nitrogen (BUN), Kt/V, parathyroid hormone (PTH), sodium (Na), and calcium (Ca). The primary outcome was SF-36 Role Limitations–Emotional. Multivariable logistic regression (dialysis cohort) and ROC analyses were performed to evaluate predictors of FMS.
Results: The prevalence of FMS within the hemodialysis cohort was 55.1% (38/69). Between-group comparisons (dialysis vs FMS) showed higher BMI in the FMS group (28.7 ± 4.8 vs 25.3 ± 5.7; p<0.001), while VAS pain and Katz ADL scores were similar. SF-36 summary scores were higher in the FMS group (PCS, p=0.039; MCS, p=0.008; Total, p=0.012). At the domain level, General Health (45.1 ± 16.1 vs 38.6 ± 13.5; p=0.015) and Role Limitations–Emotional (62.0 ± 40.2 vs 28.5 ± 38.4; p<0.001) were higher in the FMS group. Within the dialysis cohort, Role Limitations–Emotional remained higher in FMS(+) patients (36.8 ± 39.3 vs 18.2 ± 35.3; p=0.024), and post-dialysis BUN was higher in FMS(+) patients (27.5 ± 13.4 vs 19.8 ± 4.3; p=0.008). In multivariable analysis, only post-dialysis BUN was independently associated with FMS (OR=1.10; 95% CI 1.02–1.19; p=0.012). Discrimination was moderate for post-dialysis BUN alone (AUC=0.684) and improved slightly with the multivariable model (AUC=0.726).
Conclusion: FMS was common among hemodialysis patients and was associated with differences in emotional role functioning and higher post-dialysis BUN. These findings support a multidimensional approach to screening in dialysis care that integrates symptom-based FMS assessment with HRQoL profiling and selected biochemical signals.
