Type 2 diabetes, psoriasis and thiazolidinediones.
Thiazolidinediones, synthetic ligands for the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) receptor, are insulin-sensitizing drugs licensed for use in selected patients with type 2 diabetes mellitus. The potential therapeutic applications of the thiazolidinediones extend to other clinical specialties such as dermatology. Rosiglitazone and pioglitazone are being evaluated for the treatment of psoriasis. Type 2 diabetes and psoriasis may coexist prompting speculation that dual benefits might accrue for patients with both conditions. A recent open pilot study suggests that oral pioglitazone may be beneficial for moderate chronic plaque psoriasis. However, changes in antidiabetic medication must be made in the knowledge of the cautions and contraindications to oral agents as well as the impact on metabolic control. Further studies are required before the use of thiazolidinediones for psoriasis can be advocated.
