Alopecia areata responding to immunoglobulin, with varying response to different preparations

Recurrent spontaneous abortions, Hashimoto thyroiditis and alopecia totalis: response to anticoagulation and intravenous immunoglobulin therapy

INTRODUCTION

Although numerous studies indicated a link between antithyroid antibodies and recurrent spontaneous abortions (RSA), consensus on the treatment of this condition is still lacking.

CASE REPORT

We present a case of a 35-year-old pregnant woman (gestation week 4) with primary hypothyroidism, total alopecia, high level of positive antithyroid antibodies, and history of two recurrent spontaneous abortions in early pregnancy. Along with L-thyroxin substitution, intravenous human immunoglobulin (IVIg) combined with anticoagulation and antiaggregation therapy was introduced. During pregnancy her scalp hair completely re-grew, and following gestation week 39 she delivered healthy female child.

CONCLUSION

Thyroid antibodies could contribute to previous recurrent abortions in our patient. It is suggested that in older primiparas with Hashimoto thyroiditis and history of RSA, a combined treatment with IVIg, anticoagulation and antiaggregation therapy should be considered.

Raised serum 11-deoxycortisol in men with persistent acne vulgaris

OBJECTIVE

Acne vulgaris is androgen dependent but the hormonal mechanisms are unclear. Although there have been many studies of serum hormones in women with acne there are few studies in men and the results are conflicting. We have therefore carried out a further study in men.

DESIGN AND PATIENTS

Fifty men with acne vulgaris were age-matched against 50 normal men.

MEASUREMENTS

Serum levels of dehydroepiandrosterone sulphate (DHEAS), 17 alpha-hydroxyprogesterone, 11-deoxycortisol, androstenedione and testosterone were measured by radioimmunoassay, sex hormone binding globulin (SHBG) by immunoradiometric assay and LH, FSH and oestradiol by automated ELISA.

RESULTS

The acne patients had higher levels of androstenedione, median 7.35 nmol/l, (interquartile range 2-7) vs 6.05 (2.3), P = 0.004; testosterone, 21.7 nmol/l (7.5) vs 17.55 (7.7), P = 0.04; and free androgen index (FAI) 78.26 (40) vs 65.06 (20), P = 0.007, but also had higher levels of 11-deoxycortisol, 13.65 nmol/l (4.3) vs 12.0 (4.3), P = 0.022. The LH, FSH, 17 alpha-hydroxyprogesterone, DHEAS, oestradiol and SHBG levels were not significantly different. Examination of the Spearman rank correlation coefficient matrices for the serum levels of 17 alpha-hydroxyprogesterone, androstenedione and 11-deoxycortisol showed that the strongest correlation was between androstenedione and 11-deoxycortisol.

CONCLUSION

Although there was overlap between the results of the acne patients and controls the acne patients tended to have higher levels of androstenedione, testosterone, free androgen index and 11-deoxycortisol. The higher levels of 11-deoxycortisol are suggestive of 11 beta-hydroyxlase dysfunction which could be due to a primary adrenal defect or a consequence of raised androgens. Also, a pathway between androstenedione and 11-deoxycortisol has been described in sheep and, although unsubstantiated in man, requires consideration.
