Background
Current studies have suggested a close link between nesfatin‐1, an appetite‐related neuropeptide and gonadal hormones.
Objectives
We investigated the association between nesfatin‐1 serum level and erectile dysfunction severity in men with diabetes as well as the generalized anxiety disorder‐7 questionnaire, the patient health questionnaire‐9, serum testosterone, kidney and liver functions, glycated haemoglobin and lipid profile.
Materials and methods
Seventy‐five participants between 30 and 60 years were enrolled, 25 erectile dysfunction patients with type 2 diabetes (group I), 21 with diabetes and preserved erectile function (group II) and 29 healthy controls (group III). Erectile dysfunction status and severity were determined by the Arabic version of the international index of erectile function‐5 for all the participants. Psychological wellbeing was checked by the generalized anxiety disorder‐7 questionnaire and the patient health questionnaire‐9. Finally, participants were evaluated for serum nesfatin‐1, serum testosterone, kidney and liver functions, glycated haemoglobin and lipid profile.
Results
Serum nesfatin‐1 levels were significantly lower in groups I and II compared to the controls. The international index of erectile function‐5 scores had shown significant correlations with serum nesfatin‐1, serum testosterone, generalized anxiety disorder‐7, patient health questionnaire‐9, diastolic blood pressure, glycated haemoglobin, triglycerides, creatinine and albumin/creatinine ratio. Receiver operating characteristic analysis revealed that serum nesfatin‐1 ≥ 0.62 ng/ml, serum testosterone ≥2.9 ng/ml, generalized anxiety disorder‐7 score ≥7.5, patient health questionnaire‐9 score ≥5, glycated hemoglobin ≥6.4%, triglycerides ≥ 144 mg/dl, creatinine ≥ 0.85 mg/dl and albumin/creatinine ratio ≥ 26.5 are useful predictors of erectile dysfunction in men with type 2 diabetes, and the area under the curve for those variables was respectively 0.83, 0.76, 1, 0.75, 0.88, 0.72, 0.67 and 0.77. Finally, a linear regression analysis revealed that generalized anxiety disorder‐7 was the only strong independent predictor of the international index of erectile function‐5 (p < 0.001).
Discussion and conclusion
Nesfatin‐1 can be used as a biomarker for the severity of anxiety in erectile dysfunction patients with diabetes. Use of this molecule in treatment of diabetes and erectile dysfunction should be strengthened by larger studies. Psychiatric care must be offered to patients with diabetes and erectile dysfunction and low serum nesfatin‐1 as they experience intense anxiety and depression.
