> Pyrrole Disorder
> Omega 3s can worsen mental symptoms in bipolar or schizophrenic patients.... if they have a pyrrole disorder. This phenotype is dramatically short of arachidonic acid & giving omega 3 oils aggravates the situation since omega 3 and omega 6 EFA's are in competition for delta 5,6 desaturases. We use red blood cell membrane analysis for EFA's

You process flies in the face of established research.

Utilization of precursor essential fatty acids in culture by skin fibroblasts from schizophrenic patients and normal controls.

Based on the lower levels of long-chain polyunsaturated analogs of essential fatty acids (EPUFAs) in plasma membrane phospholipids of red blood cells, brain and cultured skin fibroblasts from schizophrenic patients, a defective utilization (uptake, conversion to EPUFAs and incorporation into membrane phospholipids) of precursor EFAs has been suggested. Utilization of radiolabeled linoleic (LA, 18:2(n-6)) and alpha-linolenic (ALA, 18:3(n-3)) acids was studied in cultured skin fibroblasts from patients with established schizophrenia and at the first episode of psychosis, and normal controls. Uptake and incorporation of both the EFAs were similar in fibroblasts from both groups of patients studied compared with normal controls. However, although the utilization of LA into arachidonic acid (AA, 20:4n-6) was similar in patients and controls, the utilization of eicosapentaenoic acid (EPA, 20:5(n-3)) into docosahexaenoic acid (DHA, 22:6(n-3)) was significantly lower in first-episode psychotic patients (patients, 96.33 +/- 27.16 versus normals, 161.66 +/- 26.33 nmoles per mg total protein; P = < 0.001). This data indicates that the level of delta 6- as well as delta 5-desaturase may be normal. However, the levels of delta 4-desaturase may be lower in fibroblasts from schizophrenic patients even at the first episode of psychosis.

Essential fatty acid deficiency in erythrocyte membranes from chronic schizophrenic patients, and the clinical effects of dietary supplementation.

Peet M, Laugharne JD, Mellor J, Ramchand CN.

Department of Psychiatry, Northern General Hospital Herries Road, Sheffield, UK.

There is now convincing evidence that membrane phospholipid metabolism is abnormal in schizophrenic patients. Our own studies, consistent with those of other research groups, have shown marked depletion of essential fatty acids, particularly arachidonic acid and docosahexanoic acid, in red blood cell membranes from schizophrenic patients relative to healthy control subjects. We also present preliminary evidence that similar abnormalities are present in first degree relatives of schizophrenic patients. Furthermore, it appears that changes in diet, which modify membrane levels of fatty acids, can have significant effects upon symptoms of schizophrenia and tardive dyskinesia (TD). Thus, we have found that schizophrenic patients who eat more (n-3) fatty acids in their normal diet have less severe symptoms. In a pilot study of (n-3) fatty acid supplementation we observed significant improvement in both schizophrenic symptoms and tardive dyskinesia over a 6 week period.

Schizophrenia: the role of abnormal essential fatty acid and prostaglandin metabolism.

Horrobin DF, Huang YS.

There are two series of essential fatty acids (EFAs), the n6 series starting with linoleic acid and the n3 series starting with alpha-linolenic acid. Members of both series are important in brain structure and can act as precursors for prostaglandin formation. Normally the desaturase enzymes which metabolize EFAs have a higher affinity for the n3 series. It is proposed that in schizophrenia mutant desaturases are present which prefer the n6 series. This change would account for the low levels of linoleic acid, dihomogammalinolenic acid and 1 series prostaglandins which have been reported in schizophrenia. It would also explain the high levels of arachidonic and alpha-linolenic acids and the recently described therapeutic response to alpha-linolenic acid. The abnormal pattern in n6 series EFAs in schizophrenics can almost exactly be imitated in rats by depriving them of n3 EFAs. This is the nearest experimental equivalent to an inability to metabolize EFAs because of an enzyme defect. Heterozygotes carrying such a mutant gene would have an advantage over either form of homozygote since they would be better able to cope with variations in dietary intake of n3 and n6 EFAs.

> Pyroluric mental patients will usually get worse if given fish oils, DHA, EPA, etc. They thrive on Primrose Oil, a good source of AA and other omega 6s. (June 23, 2003)

Most of the symptoms of puroluric patients arise from zinc deficiency, IMHO, as the pyrrhole effectively chelates zinc, and pulls it into the urine.
