An observational study in Acne Vulgaris, sponsored by Biruni University. Recruiting at 1 site in Turkey (Türkiye). Open to female participants aged 18 Years to 40 Years. Per ClinicalTrials.gov, last updated 2026-09-14.
Sponsored by Biruni University · Observational
Acne vulgaris is a common dermatological condition in adult women, often influenced by hormonal factors. Androgens such as dehydroepiandrosterone sulfate (DHEAS) can stimulate sebaceous gland activity, while gonadotropins (FSH and LH) reflect ovarian and hypothalamic-pituitary axis function. Although systemic isotretinoin is highly effective in severe or treatment-resistant acne, variability in treatment response has been observed among female patients. The role of baseline hormonal levels in predicting isotretinoin response remains unclear. Identifying hormonal predictors of treatment response may improve patient stratification and personalized management. Aim of the study is to evaluate whether baseline serum levels of DHEAS, FSH, and LH are associated with clinical response to systemic isotretinoin in women aged 18 years and older with acne vulgaris.
790 studies on the registry are indexed under Acne Vulgaris; 93 are open to participants now.
This study's planned enrollment of 64 is below the median of 88 across 95 observational studies indexed under Acne Vulgaris.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

The number of months and doses during which no new acne breakouts occur after starting isotretinoin treatment will be recorded.
Time frame: from enrollment to the end of treatment at 6 months

Started Jan 2026 (actual). Primary completion is estimated for Dec 2026, 11 months after the start.
Of 37 observational studies under Acne Vulgaris, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 13. This study's planned 11 months is close to that.
