Topical corticosteroid therapy and its effect on the hypothalamic-pituitary-adrenal axis.

All clinically effective topical corticosteroids have the potential for suppressing the pitutary-adrenal axis if large amounts are applied under occlusion on extensive areas. Recovery of the axis function occurs rapidly. In children, however, the risk of chronic suppression of the adrenal axis function with impairment of growth after topical treatment with potent steroids is a real one. Potent steroids in children should, therefore, only be used on refractory areas with carefully controlled quantities.

Clobetasone butyrate, a new topical corticosteroid: clinical activity and effects on pituitary-adrenal axis function and model of epidermal atrophy.

Clobetasone butyrate is a new corticosteroid, selected for study because of its combination of good activity in the vasoconstriction test and low systemic activity in animals. Formulated as an 0.05% ointment and cream (Molivate) it was clinically effective in patients with eczema, its activity being significantly greater than that of hydrocortisone 1% or fluocortolone 0.2% (Ultradil). Under conditions that predispose to maximal percutaneous absorption clobetasone butyrate ointment had minimal effect on hypothalamic-pituitary-adrenal function. In an animal model of cutaneous atrophy it caused less thinning of the epidermis than steroids other than hydrocortisone. Clobetasone butyrate 0.05% ointment and cream gave every indication of offering clinically effective topical anti-inflammatory activity with a wide margin of safety.

Plasma immunoreactive melanotrophic hormones in patients on maintenance haemodialysis.

Circulating levels of melanotrophic horomones and ACTH were determined in patients treated by maintenance dialysis for chronic renal failure. Plasma melanotrophic hormone levels were greatly increased in all patients studied (125-1100 ng/1 as compared with 12-36 ng/1 in normal adults) and were correlated with the duration of treatment. Skin pigmentation, especially in exposed areas, was notably increased, particularly in those patients with the highest plasma melanotrophic concentrations. Plasma ACTH levels were normal or only slightly raised and circulating corticosteroid concentrations, as determined by a fluorimetric method, all lay within the physiological range. The dissociation between ACTH and melanotrophic hormone levels in these patients may have been the result of a slower metabolic clearance of the latter.

Alopecia areata, autoimmunity, and Down's syndrome.

Alopecia areata occurs more often in Down's syndrome than would be expected by chance, sixty cases being found among 1000 patients with this syndrome compared with one case among 1000 subnormal controls. Because alopecia areata is associated with some organ-specific autoimmune disease and thyroid antibodies are often found in Down's syndrome sera from affected patients were examined for the presence of fluorescent autoantibodies. Antibodies against thyroid components tended to be present in female mongols with alopecia areata in comparison with females in a normal population but not in male mongols. Futhermore, eight out of 23 female mongols (35%) with alopecia areata had antibodies against thyroid components compared with two out of 23 female mongols (9%) without alopecia areata.

Angioma serpiginosum--familial incidence.

In this paper we present the first record of familial incidence in angioma serpiginosum observed in two families. The clinical and histological features are described.

Treatment of psoriasis with azathioprine.

Azathioprine treatment benefited 19 (66%) out of 29 patients suffering from severe psoriasis. Haematological complications were not troublesome and results of biochemical liver function tests remained normal. Minimal cholestasis was seen in two cases and portal fibrosis of a reversible degree in eight. Liver biopsies should be undertaken at regular intervals if azathioprine therapy is continued so that structural liver damage may be detected at an early and reversible stage.
