Effect of supraphysiologic doses of testosterone on fasting plasma total homocysteine concentrations in men with Klinefelter's syndrome.

Abstract：

OBJECTIVE:To examine the effect of supraphysiologic doses of testosterone (T) on plasma total homocysteine (tHcy) concentrations in patients with Klinefelter's syndrome (KS). DESIGN:Prospective clinical study. SETTING:University hospital. PATIENT(S):Thirty-two newly diagnosed male patients with KS, and 20 healthy, volunteer controls matched by age and body mass index. INTERVENTION(S):Testosterone was administered IM every 2 weeks for 6 months. Initially, pretreatment fasting blood samples were collected after overnight fasting. Posttreatment blood samples were drawn 7 days after the last injection. MAIN OUTCOME MEASURE(S):Plasma total homocysteine. RESULT(S):The KS patients had lower tHcy levels than the controls. However, plasma fasting tHcy concentrations increased in a statistically significant manner after 6 months of treatment. As compared with the levels among controls, pretreatment levels of the serum creatinine, hemoglobin, and hematocrit were significantly lower, and increased in a statistically significant way following treatment. Posttreatment levels of total cholesterol were statistically significantly higher than the baseline. The pretreatment folate and cobalamin levels also were statistically significantly higher in patients when compared with controls, and decreased significantly after treatment. The linear regression analysis showed that only creatinine, cobalamin, and folate were independently associated with plasma tHcy levels in patients before and after treatment. CONCLUSION(S):The patients with KS showed lower tHcy concentrations than healthy, age-matched male controls. Testosterone treatment increased plasma tHcy levels.
