Cj. Glueck et al., IMPROVEMENT IN SYMPTOMS OF DEPRESSION AND IN AN INDEX OF LIFE STRESSORS ACCOMPANY TREATMENT OF SEVERE HYPERTRIGLYCERIDEMIA, Biological psychiatry, 34(4), 1993, pp. 240-252
In 14 men and nine women referred because of severe primary hypertrigl
yceridemia, our specific aim in a 54-week single-blind treatment (Rx)
period was to determine whether triglyceride (TG) lowering with a Type
V diet and Lopid would lead to improvement in symptoms of depression,
improvement in an index of life stressors, change in locus of control
index, and improved cognition, as serially tested by Beck (BDI), Hass
les (HAS) and HAS intensity indices, Locus of Control index, and the F
olstein Mini-Mental status exam. On Rx, median TG fell 47%, total chol
esterol (TC) fell 15%, and HDLC rose 19% (all p less-than-or-equal-to
0.001). BDI fell at all nine Rx visits (p less-than-or-equal-to 0.001)
, a major reduction in a test of depressive symptoms. The HAS score al
so fell at all nine visits (p less-than-or-equal-to 0.05 - less-than-o
r-equal-to 0.001). Comparing pre-Rx baseline BDI vs BDI at 30 and 54 w
eeks on Rx, there was a major shift towards absence or amelioration of
depressive symptoms (chi2 = 5.9, p = 0.016). On Rx, the greater the p
ercent reduction in TG, the greater the percent fall in BDI (r = 0.47,
p less-than-or-equal-to 0.05); the greater the percent reduction in T
C, the greater the percent fall in HAS (r = 0.41, p less-than-or-equal
-to 0.05). Improvement in the BDI and HAS accompanied treatment of sev
ere hypertriglyceridemia, possibly by virtue of improved cerebral perf
usion and oxygenation. There may be a reversible causal relationship b
etween high TG and symptoms of depression.
