Abstract

Highlights: Depressed women have lower plasmatic levels of uric acid and higher levels of cholesterol. Female patients achieved more frequently remission in the last depressive episode and were more likely to have family history for psychiatric disorders. Depressed women globally had a better response to treatments but were more vulnerable to metabolic abnormalities. Abstract: Major Depressive Disorder (MDD) is a medical illness twice as common in women than in men lifetime. Purpose of this study is to identify gender differences in clinical and biochemical parameters in subjects affected by MDD to implement individualized treatment strategies. We recruited 234 patients (112 males and 122 females) consecutively hospitalized for MDD in Milan (Italy). Data were obtained through a screening of the clinical charts and blood analyses. Univariate analyses, binary logistic regressions and a final logistic regression model were performed. The final logistic regression model showed that female patients (compared to males) had lower plasmatic levels of hemoglobin ( p = 0.020) and uric acid ( p = 0.002), higher levels of cholesterol ( p < 0.001), had been treated with a lower number of antidepressants ( p = 0.011), presented lower red blood cells ( p < 0.001) and showed more frequently comorbidity with hypothyroidism ( p = 0.036). Univariate analyses identified also that women had an earlier age at onset ( p = 0.043), were less likely to have comorbidity with diabetes ( p = 0.002) and were less frequently treated with a psychiatric polytherapy ( p < 0.001). Finally, female patients had achieved more frequently remission in the last depressive episode ( p = 0.001) and were more likely to have family history for psychiatric disorders ( p < 0.001) than males. Female patients globally have a better response to treatments, but they seem to be more vulnerable to specific metabolic abnormalities as showed by more frequent hypercholesterolemia and lower plasma levels of uric acid. These results have to be confirmed by further studies.
