TOPLINE:
A study found significant associations between melasma and several comorbidities, including hypertension and hormonal contraception use, which were the most common.
METHODOLOGY:
- Melasma predominantly affects young women of color and often worsens in hyperestrogen states; understanding the association with comorbidities can improve surveillance and treatment strategies.
- Researchers evaluated 41,283 patients with melasma (mean age, 48.8 years; 93% women) from the TriNetX database and an equal number of matched control individuals.
- The main outcome was comorbidities including allergic rhinitis, atopic dermatitis, anticonvulsants, diabetes, hormonal contraceptives, hypothyroidism, hypertension, lupus, rosacea, skin cancer, and malignancy.
TAKEAWAY:
- Among those with melasma, 25% had hypertension and 24% used hormonal contraception, the two most commonly associated risk factors identified.
- Rosacea (odds ratio [OR], 5.1), atopic dermatitis (OR, 3.3), lupus (OR, 2.5), history of skin cancer (OR, 2.5), and history of internal malignancy (OR, 2.1) were associated with the highest risk of developing melasma (P

IN PRACTICE:
“Understanding the potential associations between these risk factors and melasma will better improve the management and monitoring of the most susceptible patients,” the authors wrote.
