Long-term metabolic effects of aripiprazole, ziprasidone and quetiapine: a pragmatic clinical trial in drug-naïve patients with a first-episode of non-affective psychosis
Abstract
The use of second-generation antipsychotics (SGA) has been associated with metabolic changes. However, there are differences in the metabolic profile between SGAs. We have previously observed that ziprasidone had a more benign early metabolic profile compared to aripiprazole and quetiapine. However, a long-term follow-up is preferred to detect clinically relevant impairment in metabolic parameters. We aimed to compare the effect of aripiprazole, ziprasidone, and quetiapine on metabolic measures in first-episode non-affective psychosis patients after 1 year of treatment. One hundred and sixty-five drug-naïve patients, suffering from a first episode of non-affective psychosis, were randomly assigned to receive quetiapine, ziprasidone, or aripiprazole. Weight and glycemic/lipid parameters were recorded at baseline and after 1 year of treatment. After 1 year of antipsychotic treatment, we found significant increments in weight, BMI, total cholesterol, LDL-cholesterol, triglycerides, and the triglyceride/HDL index in the sample as a whole. These changes produced a significant rise in the percentage of patients with obesity, hypercholesterolemia, and hypertriglyceridemia. However, when comparing the differential effect of each antips...Continue Reading

ApoE, Lipids & Cholesterol
Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases.
