Abstrakt: Aim: Present study aimed at determining lipid profiles in acutely symptomatic drug-naïve/drug-free patients of schizophrenia, comparing them with healthy controls and exploring relationships between various lipid fractions, aggression, suicidality and impulsivity in this population.
Materials and Methods: This was a cross-sectional hospital-based study, comparing patients with schizophrenia (M=46, F=14; mean age 32.40±6.6 years; 48 drug-free for 10.50±9.2 weeks) with 60 age-sex matched healthy controls. Upon recruitment, fasting venous blood samples of all subjects were analysed for total cholesterol, HDL, LDL, VLDL and TG levels, and patients were rated on PANSS for symptom severity, Modified Overt Aggression Scale for aggression, Impulsivity Rating Scale for impulsivity and Scale for Suicide Ideation for suicidality.
Results: The socio-demographic characteristics of the patients were comparable to controls. In patients, total cholesterol, HDL and LDL levels were found to be significantly lower (p<0.01) than the control group. When explored further in patients, lower total cholesterol and LDL levels showed significant negative correlations with scores on impulsivity (p<0.01) and suicidality (p<0.05); and TG level showed a negative correlation with impulsivity (p<0.05).
Conclusions: This study adds to a growing literature on a complex relationship between lipid fractions and impulsivity, suicidality and aggression in schizophrenia; providing interesting insights into the biochemical basis of human behaviour and confirming these in a developing-world population. The implications are many, including a need to review judiciously the promotion of weight loss and cholesterol reduction programmes in constitutionally vulnerable population, at least during their acutely-symptomatic states.
