Platelet Indices as a marker for early prediction of erectile dysfunction in diabetic patients.

Erectile dysfunction is one of the major concerns in diabetic patients. Platelet Indices including mean platelet volume, platelet count and platelet distribution width are important biomarkers for platelet activation and pathophysiology of atherothrombosis. Measurement of Platelet Indices may early predict erectile dysfunction in diabetic men. This study aimed to measure Platelet Indices in diabetic patients with erectile dysfunction and to correlate between them and erectile dysfunction especially of vasculogenic type. The study included 30 diabetic patients with diagnosed erectile dysfunction and 20 normal males as a control. Each patient was evaluated by history, International Index of Erectile Function-5, general and local examination, HbA1c, pharmaco-penile duplex ultrasonography and blood sample to measure Platelet Indices. Platelet distribution width and mean platelet volume were significantly higher in patients than controls (p < 0.001). Their levels were significantly higher in vasculogenic erectile dysfunction than other types (p < 0.001). No statistically significant association regards the platelet count (p > 0.05). We concluded that Platelet Indices are high in diabetic patients with erectile dysfunction especially those with vasculogenic aetiology. They can predict erectile dysfunction in diabetic men early, and so they may be considered as cheap, available and useful biomarker for early diagnosis of vasculogenic erectile dysfunction in diabetic patients.
