Changes in plasma cholesterol in mood disorder patients: Does treatment make a difference?

Objectives mine the impact of treatment in patients with acute episodes of major depressive (MD) and manic or hypomanic (M/HM) episodes and co-morbid generalized anxiety symptoms, on the total cholesterol blood levels (TC). enting series of patients with acute episodes of DSM IV-R confirmed diagnosis of MD or M/H were included. Subjects were treated with antidepressants, mood stabilizers, or both. The Hamilton depression scale (HAM-D21), the modified mania rating scale (MMRS), and the Hamilton anxiety scale (HAM-A) were utilized to evaluate clinical symptoms. Blood samples were drawn for TC estimations after 10 h of fasting on two occasions over time. The first sample was taken before treatment was started, and the second 4 weeks after treatment. The relationship between changes in TC and the severity of psychiatric symptoms, as measured on HAM-D, MMRS, and the HAM-A, were analysed. s jects (34 with MD and 22 with M/HM episodes) completed the study. About 4 weeks after treatment there was a statistically significant increase in the TC in patients with MD versus a significant decrease in patients with M/HM episodes. sion sults replicate earlier reports of significant increase in the cholesterol levels in depressed patients after treatment. We report a significant decrease of TC levels in M/HM episodes with treatment. Although the results in previous reports and in our study are statistically significant, their clinical significance requires further examination in longer-term studies.
