Abstract:
Objective To observe the effects of olanzapine treatment upon liver tat content (LFC)in first-episode schizophrenia patients.Methods A total of 25 first-episode schizophrenia patients were administered olanzapine alone with dosage ranging from 10 to 20 mg per day for eight weeks.1H-magnetic resonance spectroscopy (1H-MRS) was used for LFC measurements before and after eight-week olanzapine treatment.The results were compared with those of the normal control group (n =25).Other indicators,including body mass index (BMI),waist-height ratio (WHR),fasting plasma glucose (FPG),triglyceride (TG),total cholesterol (TC) and homeostasis model assessment of insulin resistance (HOMA-IR),were also assessed in the patients group.Results After olanzapine treatment,the LFC significantly increased against the pre-treatment level ((4.99 ± 1.79) % vs.(3.98 ± 0.83) %,t =2.958,P < 0.01),and against that of the normal control group ((4.99 ± 1.79)% vs.(4.02 ± 0.80)%,t =2.436,P<0.05).The levels of BMI,WHR,TG,TC and HOMA-IR were all significantly elevated after treatment.Before treatment,LFC was positively correlated to HOMA-IR,BMI,WHR and TG (r =0.447,0.424,0.421,0.413 ; all P < 0.05),while after treatment,LFC was positively correlated to HOMA-IR and TG(r =0.425,0.400; both P <0.05) ; the increase of LFC between pre-and post-treatment was positively correlated to the increases of HOMA-IR and WHR (r =0.478,P < 0.01 ; r =0.430,P < 0.05).After treatment,the LFC of 4 patients (16%) surpassed the threshold diagnostic value of fatty liver (LFC > 5.5%).Conclusion Olanzapine treatment would significantly elevate liver fat deposition in first-episode schizophrenia patients.
