Hand, shoulder and back stiffness in long-term type 1 diabetes; cross-sectional association with skin collagen advanced glycation end-products. The Dialong study.

AIMS

We aimed to: (i) estimate the prevalence of Dupuytren's disease, trigger finger, carpal tunnel syndrome and frozen shoulder; (ii) assess stiffness of the hand, shoulder and back; and (iii) explore the association of joint stiffness with both long-term HbA and collagen advanced glycation end-products (AGEs) in long-term type 1 diabetes mellitus (T1DM).

METHODS

Patients with T1DM from 1970 or earlier attending a specialized diabetes center were included in this cross-sectional controlled study. We collected HbA/HbA measurements from 1980 to 2015 and data on hand and shoulder diagnoses and joint stiffness through interviews, charts, and standardized examination. Skin biopsies were analyzed for collagen AGEs by liquid chromatography-mass spectrometry.

RESULTS

Lifetime prevalence of hand and shoulder diagnoses in the diabetes group (n=102) ranged from 37%-76% (frozen shoulder) versus 11%-15% in controls (n=73) (p<0.001). There was an association between joint stiffness and long-term HbA (odds ratio 2.01 [95% CI 1.10-3.7]) and the AGEs methyl-glyoxal-lysine-dimer (odds ratio 1.68 [95% CI 1.03-2.73]) and pentosidine (odds ratio 1.81 [95% CI 1.04-3.16]).

CONCLUSIONS

Patients with T1DM >45years had a very high prevalence of hand and shoulder diagnoses versus controls. Joint stiffness was associated with collagen AGEs. However, joint biopsies and prospective studies must explore this association further.
