Background:
Type-2 diabetes influences the course and severity of hand infections.
Methods:
We prospectively examined glucose metabolism in 90 patients with hand infection, distinguishing between normal, prediabetic and diabetic states. HbA1c-levels were evaluated prior to surgery. Patients with normal levels took an oral glucose tolerance test and those diagnosed with prediabetes were retested after the infection subsided. Hospital stay, number of surgical interventions and inflammatory markers were examined per group.
Results:
Sixty-two patients (68.8%) had abnormal glucose metabolism: 17 (18.9%) with history of diabetes and 11 (12.2%) newly diagnosed. Prediabetes was observed in 34 patients (37.8%). At follow-up, prediabetes and diabetes were diagnosed in 7 cases each, and physiological glucose metabolism was observed in 3 patients. For the 11 patients unable to undergo a second oral glucose tolerance test, detailed phone calls confirmed absence of diabetes. C-reactive protein levels were significantly elevated in diabetic patients compared to those with normal glucose metabolism (p = 0.001) or prediabetes (p = 0.034). Patients with history of diabetes were significantly older than those with normal glucose tolerance (p = 0.001) or prediabetes (p = 0.017). There were no significant intergroup differences in thrombocyte count, length of hospital stay, interval from injury to admission or the number surgical interventions.
Conclusion:
Glucose metabolism should be assessed in patients with hand infections and reassessed after the infection has subsided in prediabetic cases.
