ascorbic-acid and Acromegaly

The aim of this study was to compare antioxidant vitamin C and vitamin E levels in the non-acromegaly control group and in patients with acromegaly with and without remission.. In this study, 100 cases, acromegaly patients of 57% (n=57, 29F, 28M, mean ages of 49.5±12.1) and control subjects of 43% (n=43, 29F, 14M, mean ages of 49.6±9.2). Acromegaly patients were classified into two groups; active acromegaly (AA; n=33) and controlled acromegaly (CA; n=24).. Vitamin C levels were significantly lower in the acromegaly group [7.6 (4.7) mg/L, as median (IQR)] when compared to the control group [12.2 (5.5) mg/L, as median (IQR)] (p <0.001). Vitamin E levels didn't show a significant difference between the acromegaly and the control groups (14.2±3.6 vs. 14.8±3.7, as mean±SD, respectively, p = 0.439). Correlation analysis showed that vitamin C levels were not significantly associated with clinical, anthropometric and laboratory parameters in the acromegaly group. Vitamin E levels were significantly associated with the total cholesterol, triglyceride, LDL-C, HDL-C, APO A1, APO B both in the acromegaly and the control groups.. This study is the first one to investigate the relationship between the levels of vitamin C & E and anthropometric & metabolic parameters in acromegaly patients and control group. In our study, vitamin C level was significantly lower in the acromegaly group compared to the level in the control group. There was no significant difference in vitamin E levels between the acromegaly and control group.
