Are dexamethasone suppression test nonsuppression and thyroid dysfunction related to a family history of dementia in patients with major depression? An exploratory study.

OBJECTIVE: Recent data suggest that the low thyroid function syndrome in depression is nonspecific. They also suggest that depression may constitute a risk factor for the development of dementia, especially in atypical patients who have high rates of hypothalamo-pituitary-adrenal axis disorders. This study aimed to search for correlations among Dexamethasone Suppression Test (DST) cortisol levels, thyroid indices, and family history of dementia in patients with depression. METHODS: A sample of 30 patients, aged 21 to 60 years and suffering from major depression according to DSM-IV criteria, took part in the study. Three had a family history of dementia in first-degree relatives. We measured their serum levels of free T3, free T4, thyroid-stimulating hormone, thyroid binding inhibitory immunoglobulines, thyroglobulin antibodies, and thyroid microsomal antibodies (TMAs). We applied the 1-mg DST to all patients. The statistical analysis included 1-way multivariate analysis of covariance using t tests as the post hoc tests. RESULTS: Significantly higher levels of TMAs were found in patients with a family history of dementia, compared with those who did not have this family history. CONCLUSION: The results of this study suggest that a more pronounced autoimmune process may characterize depression patients with a family history of dementia.

Transient appearance of lactate dehydrogenase (LDH)-linked immunoglobulin and thyroid dysfunction at the postpartum period.

Here, we report a 28-year-old woman who transiently showed lactate dehydrogenase (LDH)-linked immunoglobulin during postpartum thyroiditis. She demonstrated high levels of serum LDH (794 IU/l) and thyroid hormones 7 months after delivery. Electrophoretic isoenzyme analysis of LDH showed an abnormal broadband caused by LDH-linked immunoglobulin (IgG-kappa). Transient thyrotoxicosis due to postpartum thyroiditis improved without any specific treatment, and elevated serum concentration of LDH decreased to the normal level (395 IU/l) with disappearance of LDH-linked IgG. LDH-linked immunoglobulin may also appear at the postpartum period.

[Reversible alterations of peripheral nerve function in thyroid dysfunction (author's transl)].

In 7 patients with hyperthyroidism and 9 patients with hypothyroidism both thve before treatment and after a period of normal thyroid function of at least one year duration. As far as conduction velocity and relative refractory period are concerned there was no difference between hyperthyroid patients and normal persons, whereas in cases of hypothyroidism before treatment the conduction velocity was shown to be significantly reduced; moreover a prolonged relative refractory period and a decline in amplitude of the nerve action potential were found. These alterations of peripheral nerve function, interpreted as evidence of neuropathy, proved to be reversible when the thyroid function returned to normal.
