Ultrasonographic assessment of entheseal sites of upper and lower extremities in hemodialysis patients using Madrid Sonography Enthesitis Index

BMC Musculoskelet Disord. 2022 Jun 23;23(1):606. doi: 10.1186/s12891-022-05512-5.


BACKGROUND: There is no much information about the entheseal involvement among hemodialysis (HD) patients. The aim of this study was to assess the frequency and distribution of ultrasonographic (US) entheseal alterations in HD patients and to evaluate the association between US abnormalities and both clinical and laboratory data.

METHODS: This study was conducted on 41 HD patients and 23 sex- and age- matched controls. All participants were evaluated clinically for any signs of enthesopathy. Six entheses sites were scanned bilaterally using grey scale (GS) and power Doppler (PD) US and were scored using Madrid Sonography Enthesitis Index (MASEI) scoring system.

RESULTS: In HD patients, at least one clinical sign suggestive of enthesopathy was found in 69 (14%) of 492 entheses. HD patients had statistically significant higher scores of structural tendon abnormalities (p < 0.001), enthesis thickening (p < 0.001), bone erosions (p < 0.001) and calcification (p = 0.037) than the healthy controls. Total MASEI score was higher in HD patients than healthy controls (median;18 vs 8, p < 0.001), also, MASEI-inflammatory (median;11 vs 3, p < 0.001) and damage scores (median;6 vs 0, p < 0.001). There was a statistically significant positive association between total MASEI score and both age (p = 0.032) and duration of HD (p = 0.037). Duration of HD was predictive for both MASEI-damage component (p = 0.004) and total MASEI score (p = 0.014).

CONCLUSION: There is a high prevalence of subclinical enthesopathy in HD patients. The entheseal US alterations is much higher in HD patients than in healthy subjects. The duration of HD is the significant predictor of enthesopathy in HD patients.
