Desquamative inflammatory vaginitis: what is it?
J Reprod Med 2008 Feb;53(2):124-8.PMID:18357804doi
Objective: To record the inflammatory patterns found in desquamative inflammatory vaginitis and to investigate further the existence of an idiopathic subset of this condition. Study design: This was a retrospective case note study of 11 women over a 12-month period who presented with symptoms of painful sexual intercourse and increased vaginal discharge. Results: Examination of the vulva was usually normal or showed mild erythema and a thin purulent discharge. Examination of the vaginal wall showed erythema consistent with inflammation. A biopsy from the vaginal wall showed essentially 2 patterns of inflammation: either a lichenoid or a nonspecific mixed inflammatory infiltrate. Therapy with clindamycin and Clobetasone Propionate was largely effective. Conclusion: While this study does not fully answer the histology of desquamative inflammatory vaginitis, it does highlight the need for further study to identify whether there is an idiopathic subset of desquamative inflammatory vaginitis or whether it is erosive lichen planus.
Tinea versicolor of the neck as side effect of topical steroids for alopecia areata
J Dermatolog Treat 2019 Dec;30(8):757-759.PMID:30668183DOI:10.1080/09546634.2019.1573308.
Background: Treatment of alopecia areata (AA) involves use of high potency topical corticosteroids under occlusion that, even very effective, can lead to several adverse effects. Objective: We report 10 cases of patients with AA that, after using high potency topical corticosteroids, have developed tinea versicolor of the neck area. Methods: Ten patients with AA, aged 18-38 years, were prescribed with Clobetasone Propionate 0.05% cream under occlusion every other day but, after 3-4 months of treatment, they returned to our facility complaining the appearance of multiple white or red-brown round or oval macules in the neck area. Results: Diagnosis of pityriasis versicolor was confirmed by direct microscopy examination of skin scrapings in 10% potassion hydroxide (KOH) solution. All patients received systemic antifungal therapy associated with the daily use of ketoconazole shampoo. Conclusion: Tinea versicolor of the neck should be included among a rare but possible side effect of prolonged application of high potency topical steroids on the scalp. These cases reinforce the importance of careful dermatologic examination and recommend preventive measures in patients with alopecia areata that are using these drugs.
Liquid chromatographic determination of clobetasone-17-butyrate in ointments
J Assoc Off Anal Chem 1990 Nov-Dec;73(6):893-5.PMID:2289922doi
A liquid chromatographic (LC) method has been developed for determination of clobetasone-17-butyrate in ointment using Clobetasone Propionate as an internal standard. Separation was carried out on a C18 reverse-phase column using water-methanol as a mobile phase. Methylparaben and propylparaben (both sodium salt) used as preservatives did not interfere with separation. Compounds are detected photometrically at 235 nm. Mean assay results for 0.05% commercial ointments were 100.36% (n = 5). Mean recovery of clobetasone-17-butyrate added to commercial ointment was 99.89%.
Topical steroid containing combinations: Burden of adverse effects and why the recent regulatory action may not be enough
Indian J Pharmacol 2021 Sep-Oct;53(5):371-376.PMID:34854405DOI:10.4103/ijp.IJP_728_19.
Objectives and methods: In September 2018, the government of India banned 328 fixed dose combinations (FDCs), 24 of which are combinations containing topical steroids. To assess what impact can be expected from this regulatory action, we analyzed reports of adverse drug events due to topical corticosteroids at a hospital-based pharmacovigilance center between January 2017 and August 2018. Results: Among 34 different steroid-containing FDCs responsible for 485 reports of ADEs with topical steroids, only three preparations, accounting for 50.10% of ADEs, come under the umbrella of the recent ban. Clobetasone Propionate (68.87%) and betamethasone (28.45%) were the corticosteroids most frequently associated with adverse events. Most of the steroid preparations (87.84%) had been bought without a prescription for the treatment of dermatophytoses (76.70%). Males (77.73%) were predominantly affected, and nearly half (47.43%) of the patients were between 21 and 30 years of age. Skin atrophy (50.10%), striae (25.54%), and hypopigmentation (19.79%) were the major ADEs. Conclusion: Nearly half of the cutaneous adverse effects were due to topical steroid combinations which are still widely available over the counter.
