Reported alcohol consumption was quantified and scored by a validated questionnaire administered by an interviewer to 64 patients (10 female) with Dupuytren's contracture (DC) before hand surgery and to 89 controls (44 female) admitted for other hand or foot surgery. Serum urate (SUA), gamma-glutamyl transferase (GGT), and mean red cell volume (MCV) were measured on admission. Thirteen of 54 men with DC reported current daily alcohol intake of 40 g or more compared with one of 45 male controls (p = 0.0001). Two of 10 women with DC (but none of 44 controls) admitted consuming at least 40 g alcohol daily (p = 0.03). MCV was higher in men (but not women) with DC than in controls (p less than 0.0005). Current alcohol consumption score of patients with DC correlated with SUA (r = 0.308, p less than 0.05), MCV (r = 0.44, p less than 0.01), and GGT (r = 0.54, p much less than 0.001) on admission. DC among men is strongly associated with heavy drinking, reflected both in self reporting and haematological data.
