Adrenocorticotropic hormone (ACTH) level and adrenal deficiency in patients with mucocutaneous pemphigus.

Objectives: This study aimed to evaluate the level of adrenocorticotropic hormone (ACTH) and adrenal insufficiency in patients with mucocutaneous pemphigus lesions who use oral corticosteroids.

Methods: This descriptive-analytical study was performed on 54 patients (48.44 ± 12.74 years) with mucocutaneous pemphigus in 2019. Those patients taken corticosteroids in different doses and way. At first, collected patients information including age, sex, type of pemphigus, duration of use, patient dosage, duration of corticosteroid administration, and method of administration were collected daily. Adrenal gland function was measured by evaluating ACTH levels. Data were analyzed by using Pearson correlation coefficient and t-test.

Results: Our study showed that 37 cases (68.5%) had normal ACTH average hormone level (7.3-63.3 mL/pg), 11 cases (20.4%) were lower levels (<7.2 mL/pg), and 6 cases (11.1%) were higher levels (63.3 > mL/pg). Wo observed no significant relationship between ACTH and duration of corticosteroids usage (p=0.207).

Conclusions: Taking a maintenance dose of between 12.5 and 25 mg daily does not usually lead to adrenal insufficiency. The present study showed that the lower the daily dose of corticosteroids, the lower the likelihood of adrenal insufficiency.
