TOPLINE:
, but more information is needed on dosing and barriers to treatment.
METHODOLOGY:
- Acne can be a side effect of masculinizing hormone therapy for transmasculine individuals. While isotretinoin is an effective treatment option for acne, its effectiveness and safety in transgender and gender-diverse individuals are not well understood.
- This retrospective case series included 55 patients (mean age, 25.4 years) undergoing masculinizing hormone therapy at four medical centers, who were prescribed isotretinoin for acne associated with treatment.
- Isotretinoin treatment was started a median of 22.1 months after hormone therapy was initiated and continued for a median of 6 months with a median cumulative dose of 132.7 mg/kg.
- Researchers assessed acne improvement, clearance, recurrence, adverse effects, and reasons for treatment discontinuation.
TAKEAWAY:
- Overall, 48 patients (87.3%) experienced improvement, and 26 (47.3%) achieved clearance during treatment. A higher proportion of patients experienced improvement (97% vs 72.7%) and achieved clearance (63.6% vs 22.7%) with cumulative doses of ≥ 120 mg/kg than those who received cumulative doses < 120 mg/kg.
- The risk for recurrence was 20% (in four patients) among 20 patients who achieved clearance and had any subsequent health care encounters, with a mean follow-up time of 734.3 days.
- Common adverse effects included dryness (80%), joint pain (14.5%), and headaches (10.9%). Other adverse effects included nose bleeds (9.1%) and depression (5.5%).
- Of the 22 patients with a cumulative dose < 120 mg/kg, 14 (63.6%) were lost to follow-up; among those not lost to follow-up, 2 patients discontinued treatment because of transfer of care, 1 because of adverse effects, and 1 because of gender-affirming surgery, with concerns about wound healing.
IN PRACTICE:
“Although isotretinoin appears to be an effective treatment option for acne among individuals undergoing masculinizing hormone therapy, further efforts are needed to understand optimal dosing and treatment barriers to improve outcomes in transgender and gender-diverse individuals receiving testosterone,” the authors concluded.
SOURCE:
The study, led by James Choe, BS, Department of Dermatology, Brigham and Women’s Hospital, Harvard Medical School, Boston, was published online in JAMA Dermatology.
LIMITATIONS:
The study population was limited to four centers, and variability in clinician- and patient-reported acne outcomes and missing information could affect the reliability of data. Because of the small sample size, the association of masculinizing hormone therapy regimens with outcomes could not be evaluated.
DISCLOSURES:
One author is supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Three authors reported receiving grants or personal fees from various sources. The other authors declared no conflicts of interest.
