Color blindness not closely linked to bipolar illness. Report of a new pedigree series.

A new pedigree series of bipolar manic-depressive patients admitted to the National Institute of Mental Health intramural research program was evaluated for linkage between bipolar illness and red-green color blindness, since previous studies had indicated that close linkage was generally present. Using family study methods, six informative pedigrees were investigated. Analysis was performed using a multigenerational procedure and taking into account variable penetrance. Close linkage could be definitively ruled out as a general finding. Bipolar and related illnesses are thus not generally transmitted by a single major gene close to the protan/deutan region of the human X-chromosome.

New data do not suggest linkage between the Xg blood group and bipolar illness.

The Xg blood group antigen (a genetic marker of a region of the X chromosome at a considerable distance from protan/deutan color blindness) was studied for linkage to bipolar manic-depressive illness. A multigenerational analytic method, taking variable penetrance into account, was used. In our series of six informative pedigrees, very close linkage could be definitively ruled out, and the likelihood of less tight linkage was consistently less than the likelihood of nonlinkage.

Postpartum mania in bipolar manic-depressive patients withdrawn from lithium carbonate.

Three women, previously diagnosed as bipolar I manic-depressive, were withdrawn from lithium carbonate prophylaxis immediately prior to their pregnancies. The patients had been euthymic while on lithium carbonate for at least 3 1/2 years prior to their pregnancies. Two of the three patients developed a manic syndrome within 2 weeks postpartum. The use of lithium carbonate during pregnancy, and particularly in the postpartum period, requires reassessment. We advocate an ongoing clinical relationship and the reinstitution of lithium in the third trimester in most cases.

Human leukocyte antigen system not closely linked to or associated with bipolar manic-depressive illness.

An association and linkage study of the HLA system and bipolar affective illness is reported. HLA B-14 showed an increased frequency and HLA-Bw27 a decreased frequency in 92 bipolar patients compared to 210 controls, but significance is not reached when appropriate statistical corrections are made. It is shown that ethnological differences can lead to sampling biases; a purported increased frequency of HLA-Bw 16 in Ashkenazi Jewish bipolar patients is negated when ethnologically similar controls are used. The transmission of HLA alleles in nine families with at least two generations of affective illness revealed independent assortment, and nonlinkage to either locus A or B was demonstrated using a multigenerational method of linkage analysis. The nonreplicability of the HLA association studies, and the failure to demonstrate linkage of the HLA loci with afe development of affective illness, although further analyses are necessary.

Screening for PKU heterozygosity in bipolar affectively ill patients.

There were no significant differences noted between bipolar manic-depressive patients and normal controls for plasma phenylalanine or tyrosine following an L-phenylalanine loading test given to determine if some affective illness may be related to the heterozygous phenotypic expression of phenylketonuria (reduced liver phenylalanine hydroxylase). The test was able to distinguish known PKU heterozygotes from the other subjects. It is possible that other heterozygous states may be implicated in the development of some psychiatric disorders.

Menstrual cycle phase and psychiatric admissions.

Several surveys have demonstrated increased psychiatric admissions during the para-menstrual phases of the menstrual cycle (4-5 days before and during the onset of menses). We assessed menstrual cycle phase in 51 carefully diagnosed women at the time of emergency psychiatric admission and contrasted their cycle phase distribution with 113 normal hospital staff members assessed at random upon arrival at work. Consistent with other studies, 47% of psychiatric admissions occurred during the para-menstrual phase in contrast to 22% of staff controls (chi 2 = 9.27; df = 1; P = 0.002). Within the group of psychiatric patients, 33.3% of admissions occurred within 4 days of the onset of menses (chi 2 = 12.45; df = 6; P = 0.052). There were no significant phase differences found between major depressive and schizophrenic patients, between acutely suicidal and non-suicidal patients, and no significant correlation was noted with depression rating scales. Thus, it appears that menstrual cycle entrainment and associated late luteal phase biological changes may have additive effects which are sufficient to exacerbate the expression of psychiatric disorder in vulnerable patients, independent of their diagnosis.
