OBJECTIVE: The aim of our study was to evaluate the frequency of skin
manifestations, including the diabetic hand syndrome, in young IDDM
patients. In addition, we studied the relation of the cutaneous
manifestations to diabetes duration, glycemic control, and microvascular
complications. RESEARCH DESIGN AND METHODS: The frequency of skin
manifestations, including the diabetic hand syndrome, were examined in 238
IDDM patients (disease duration > 5 years) and 122 healthy control
subjects in a cross-sectional study. In addition, we studied the relation
of the cutaneous manifestations with diabetes duration, glycemic control,
BMI, microvascular complications, and stratum corneum hydration using a
stepwise logistic regression. RESULTS: Diabetic skin manifestations were
detected in 168 of 238 (71%) IDDM patients and in 18 of 122 (14%) of the
control subjects. Ichthyosiform skin changes of the shins, scleroderma-like
skin changes, tinea pedis, and dry scaly palms were detected in 48 vs. 7%,
39 vs. 0%, 32 vs. 7%, and 21 vs. 0.8% of the patients and control subjects,
respectively. In the diabetic patients, a significant association was found
between ichthyosis of the shins and scleroderma-like skin changes of the
hand (P < 0.001) and between scleroderma-like skin changes and the skin
dryness of the palms (P < 0.0001). When diabetic risk factors were
considered, diabetes duration was significantly associated with
scleroderma-like skin changes and ichthyosis of the shins (P < 0.0001).
The latter was also found to be related to diabetic retinopathy (P <
0.0001). Keratosis pilaris was present in 21% of the patients versus 9% in
control subjects and was found to be exclusively associated with high BMI.
CONCLUSIONS: Acquired ichthyosis is a common finding and the most prevalent
skin manifestation in young IDDM patients. The development of several skin
manifestations in insulin-dependent patients seems to be related to
duration of diabetes and to development of diabetic microvascular
complications.
