Cutaneous adverse effects of biologic medications

Area of Science:

• Oncology
• Dermatology
• Pharmacology

Background:

• Biologic therapies are increasingly utilized for various conditions.
• Cutaneous adverse effects are common complications of these treatments.
• Understanding these side effects is crucial for patient management.

Purpose of the Study:

• To review the spectrum of cutaneous adverse effects associated with common biologic therapies.
• To provide guidance on managing these dermatologic reactions.
• To identify criteria for referral to a dermatologist.

Main Methods:

• Literature review of adverse cutaneous events related to specific drug classes.
• Analysis of reported side effect profiles for tumor necrosis factor (TNF) alpha inhibitors.
• Examination of side effects for epidermal growth factor receptor (EGFR) inhibitors and small-molecule tyrosine kinase inhibitors (TKIs).
• Review of reactions to cell surface-targeted monoclonal antibodies.

Main Results:

• Common adverse skin reactions include rash, pruritus, and xerosis.
• Specific patterns of cutaneous toxicity are associated with different drug classes.
• Early recognition and management can mitigate severity and improve patient outcomes.

Conclusions:

• Cutaneous adverse effects are a significant concern with biologic therapies.
• Appropriate management strategies can often resolve or control these reactions.
• Dermatologist consultation is essential for complex or persistent cases.
