Potassium Iodide for Cutaneous Inflammatory Disorders: A Monocentric, Retrospective Study

Area of Science:

• Dermatology
• Pharmacology

Background:

• Potassium iodide (KI) is a long-standing dermatological treatment.
• Recent data on KI efficacy is limited.

Purpose of the Study:

• To retrospectively evaluate the therapeutic response to Potassium iodide (KI).

Main Methods:

• Retrospective analysis of 35 patients treated with KI over 20 years (1998-2017).
• KI was prescribed for conditions including erythema nodosum and sarcoidosis.

Main Results:

• Improvement observed in approximately one-third of patients.
• No response in 14 patients; disease progression in 9.
• Adverse events documented in 16 out of 35 patients.

Conclusions:

• KI demonstrated limited efficacy, with improvement in only about a third of cases.
• Mild side effects were noted in nearly half of the patients.
