tretinoin and Sweat-Gland-Diseases

The retinoids are synthetic derivatives of vitamin A. Isotretinoin (13-cis-retinoic acid) is now being widely used in the United States for severe acne and etretinate is available in Europe and other countries for psoriasis. These drugs are also effective for a number of other skin diseases. This is an attempt to review basic knowledge of retinoids with which the practicing dermatologist should be familiar, to review the current status of studies, and to speculate on the present and future roles of these drugs in dermatology.

In the one year since isotretinoin has been available in the United States for the treatment of severe, recalcitrant, nodulocystic acne, there has been extensive clinical verification of the reports of its dramatic efficacy in the treatment of this troublesome disease. Proper selection of patients, as well as treatment with adequate doses of drug for 3 to 5 months, will most often result in significant clinical improvement or total clearing. Although dosages of less than 1 mg/kg/day may produce a nearly equivalent degree of improvement with somewhat fewer or less severe side effects, the recommended daily dose remains 1 mg/kg/day because lower dosages are associated with more frequent relapses. In severe cases, the daily dosage may be increased to 2 mg/kg/day. Teratogenicity, elevation of serum triglycerides, liver function abnormalities, pancreatitis, and pseudotumor cerebri may all be associated with isotretinoin therapy and require close monitoring of the patient.

Eight patients with a long-standing hidradenitis suppurativa were treated with isotretinoin, 0.71 to 1.2 mg/kg/day, as a single agent for 4 months and have had follow-up of at least 2 months. The clinical status was judged as cleared in one patient, almost cleared in three patients, improved in one patient, not changed in two patients, and worse in one patient.

Hidradenitis suppurativa, a chronic relapsing disease of apocrine gland-bearing areas, most frequently occurs in the axillae, groin, perineal, and perianal regions. Hidradenitis of vulva is frequently misdiagnosed and inadequately treated. The case of a 15-year-old nulliparous black female adolescent referred for evaluation of multiple draining fistulas of the anogenital region is presented. Diagnostic studies for granulomatous disease were negative. Results of a barium enema were normal and biopsies were compatible with the diagnosis of hidradenitis suppurativa. She was treated for 22 weeks with isotretinoin, 1 mg/kg daily, with an excellent response. Side effects were minor and included cheilitis, mild xerosis, and a transient elevation of serum alkaline phosphatase levels. Few patients with severe hidradenitis have been responsive to this synthetic vitamin A derivative. A review of the literature indicates that the results of treatment with isotretinoin for hidradenitis have been at best equivocal. Isotretinoin should never be used during pregnancy because of known teratogenic effects. Women of childbearing age must use effective contraception during treatment.

56 patients with nodulocystic acne, hidrosadenitis (2 cases) and steatocystoma multiplex (2 cases) were treated with oral isotretinoin. 52 patients cleared completely or were much improved without local treatment; 2 failures involved patients with steatocystoma, while 2 patients with ano-inguinal lesions were only improved. 19 patients received a dose of 0.5 mg/kg/day for six months; in 37 patients the dose was adapted to the initial response but did not exceed 1 mg/kg/day. Reversible elevated triglyceride concentration was observed in 5% of the patients. 18 patients were followed up and 4 (22%) presented moderate relapses.
