OBJECTIVES: Many afflictions have been associated with celiac disease, but chance associations may exists. The aim of this study was to establish, by means of a multicenter prospective study, the prevalence of thyroid impairment among adult patients with newly diagnosed celiac disease and to evaluate the effect of a 1-yr gluten withdrawal on thyroid function. METHODS: A total of 241 consecutive untreated patients and 212 controls were enrolled. In 128 subjects a thorough assessment, including intestinal biopsy, was repeated within 1 yr of dietary treatment. Thyroid function was assayed by measuring the levels of TSH, free T3, free T4, thyroperoxidase, and thyroid microsome antibodies. RESULTS: Thyroid disease was 3-fold higher in patients than in controls (p < 0.0005). Hypothyroidism, diagnosed in 31 patients (12.9%) and nine controls (4.2%), was subclinical in 29 patients and of nonautoimmune origin in 21. There was no difference regarding hyperthyroidism, whereas autoimmune thyroid disease with euthyroidism was present in 39 patients (16.2%) and eight controls (3.8%). In most patients who strictly followed a 1-yr gluten withdrawal (as confirmed by intestinal mucosa recovery), there was a normalization of subclinical hypothyroidism. Twenty-five percent of patients with euthyroid autoimmune disease shifted toward either a subclinical hyperthyroidism or subclinical hypothyroidism; in these subjects, dietary compliance was poor. In addition, 5.5% of patients whose thyroid function was normal while untreated developed some degree of thyroid dysfunction 1 yr later. CONCLUSIONS: The greater frequency of thyroid disease among celiac disease patients justifies a thyroid functional assessment. In distinct cases, gluten withdrawal may single-handedly reverse the abnormality.

The aim of this study was to evaluate whether the urinary excretion of low molecular weight peptides is increased in women with a history of anorexia nervosa/self starvation. The study group consisted of 12 women aged 20-38 years who were treated in a specialised day care unit for eating disorders in Stockholm between January and December 1998; the controls were eight women with primary bulimia treated in the same unit (A) and ten healthy women without any eating disorder (B). The chromatographically measured urinary peptide levels in the study group were significantly higher than those in control group A (and B when one highly influential individual with very low peptide excretion in the study group was excluded from the analyses). These findings offer some support to the speculative hypothesis that eating disorder symptoms may be linked to increased levels of neuroactive peptides, although it is necessary to define the peptides further before any definite conclusion can be drawn. Furthermore, the study group was characterised by many interpersonal differences in eating behaviour that could explain the increased urinary peptide levels.
