    BACKGROUND: Shoulder involvement is frequently observed in chronic renal disease (CRD) and hemodialysis patients. OBJECTIVE: Our aim is to compare shoulder Magnetic Resonance Imaging (MRI) findings of stage 4 CRD patients naive to dialysis, hemodialysis patients and healthy controls. METHODS: Twenty hemodialysis patients with shoulder pain (Group 1), 30 hemodialysis patients without shoulder pain (Group 2), 20 patients with stage 4 CRD (Group 3) and 30 healthy controls (Group 4) were enrolled. Urea, creatinine and beta 2 microglobulin were measured. Thickness, homogeneity and integrity of rotator cuff and presence of effusion were examined by MRI. RESULTS: Supraspinatus tendon was thicker in Group 1 compared to other groups, whereas infraspinatus tendon was thicker in Group 1 compared to Groups 2 and 4. Although all tendons thickness was higher in Group 3 than Group 4, there was no significant difference. Most effusion areas were present in Group 1, followed by Groups 2 and 3. There was a significant correlation between glomerular filtration rate and thickness of supraspinatus, infraspinatus tendons and between beta 2 microglobulin and thickness of infraspinatus, subscapularis tendons and total number of areas with effusion. CONCLUSIONS: Increased shoulder tendon thickness and effusion were detected in symptomatic dialysis patients, while greater effusion areas were detected in asymptomatic dialysis patients and in stage 4 CRD patients who do not require dialysis compared to healthy controls.

    Painful and painless shoulder Magnetic Resonance Imaging comparisons in hemodialysis patients and correlation with clinical findings
    (Ios Press, 2017) Turk, Ayla Cagliyan; Fidan, Nurdan; Ozcan, Oguzhan; Ozdemir, Ferda; Tomak, Leman; Ozkurt, Sultan; Sahin, Fusun
    BACKGROUND: Shoulder pain is frequently observed in haemodialysis patients. OBJECTIVE: To compare haemodialysis patients with or without shoulder pain in terms of shoulder motion ranges, beta 2 microglobulin levels and magnetic resonance imaging findings. METHODS: Forty-three patients undergoing dialysis were enrolled, of which 23 patients had explicit shoulder pain at night, which appeared during dialysis. Range of joint motion was evaluated. beta 2 microglobulin value was recorded. MRI was used to evaluate rotator cuff tendons for thickness, homogeneity, integrity and presence of effusion. RESULTS: Ranges of motion were significantly lower in the painful shoulder group. Supraspinatus tendon thickness and the number of areas with effusion were higher in the painful group. There was a positive correlation between the beta 2 microglobulin level and supraspinatus (r:0.352 p < 0.05) and subscapular (r:0.454 p < 0.05) tendon thicknesses. While effusion areas and pain (r:0.351 p < 0.05) showed positive correlation, there was a negative correlation between pain and shoulder motion ranges. CONCLUSIONS: Shoulder pain in dialysis patients can be related with tendon thickness and effusion. While the beta 2 microglobulin level affects tendon thickness, it has no relation to pain and movement constraint.
