Brief Summary:
The links between low LDL-C levels and psychologic symptoms (psychotic disorders, mood disorders, aggressivity, suicidal risk, etc.) and cognitive deficits (mainly executing functioning) are debated. The PARTITION study aims at estimating the prevalence of hypobetalipoproteinemia (HBL), defined as a LDL-C level ≤ 0,50 g/L, in a psychiatric population.

Condition or disease Intervention/treatment Phase
Familial Hypobetalipoproteinemia Diagnostic Test: Psychiatric population Not Applicable

Detailed Description:

Some forms of hypobetalipoproteinemia (HBL) are associated with a longevity syndrome and cardiovascular protection due to prolonged exposure to low levels of LDL-C. However, while LDL-C reduction has been studied extensively for its beneficial effect on cardiovascular risk, other studies have reported that low levels of LDL-C (either spontaneous or artificially occurring with low-fat diets or lipid-lowering drugs) may be associated with psychiatric symptoms (psychotic or mood disorders, aggression, suicidal attempts, etc.) or altered cognitive performance (particularly executive functioning). These studies have led to contradictory results, and the possible link between low LDL-C levels and psychiatric symptoms remains highly controversial so far.

The PARTITION study aims at estimating the prevalence of hypobetalipoproteinemia (HBL), defined as a LDL-C level ≤ 0,50 g/L, in a psychiatric population. Moreover, the study includes the characterization of psychiatric disorders as well as psychological and personal characteristics associated with HBL. The evolutionary profile of patients with and without HBL will be studied. Genetic characteristics and biomarkers of HBL will also be studied.

Arm Intervention/treatment
Experimental: Psychiatric population

At inclusion: Patients will have A Lipid Panel Test, other biological analyzes and a clinical assessment. In case of a low LDL-C level (≤ 0, 50 g/L), genetic analyzes will be performed to screen for genetic forms of hypobetalipoproteinemia (HBL).

At 2- 4 weeks: for patients with HBL (LDL-C ≤ 0,50 g/L with no secondary cause of LDL-C reduction), another Lipid Panel Test will be performed to confirm the maintenance of the low LDL-C level.

At 6 months : Patients with a HBL will perform a full biological examination, and the LDL-C levels and genetic analyzes will be confirmed. A dietary survey will be performed, together with a psychiatric assessment. The same numbers of matched controls will performed a quick telephone interview to collect the psychiatric characteristics.

  1. Evaluation of primary hypobetalipoproteinemia prevalence defined by a spontaneously low level of LDL-C [ Time Frame: at baseline (admission at the hospital) ]
    LDL-C level < 0,50 g/L
