Leprosy reactions, not the bacteria, cause irreversible nerve damage. Early recognition of these inflammatory reactions is crucial for preventing long-term leprosy complications.

Area of Science:

Immunology
Neurology
Infectious Diseases

Context:

Leprosy, caused by Mycobacterium leprae, presents unique challenges due to slow bacterial proliferation.
The primary source of irreversible morbidity in leprosy stems from "reactions," which involve inflammatory damage to peripheral nerves.

Purpose:

To review recent advances in understanding leprosy reactions.
To discuss the pathogenesis, immunology, clinical features, pathology, treatment, and prevention of leprosy reactions.

Summary:

Leprosy reactions are immune-mediated inflammatory events causing significant peripheral nerve damage and morbidity.
These reactions can be the initial presentation of leprosy, necessitating awareness in patients with cutaneous lesions or nerve disturbances.
This review synthesizes current knowledge on the multifaceted aspects of leprosy reactions.

Impact:

Highlights the critical role of "reactions" in leprosy pathogenesis and patient outcomes.
Emphasizes the need for heightened clinical suspicion for leprosy and its reactions in relevant patient populations.
Provides a comprehensive overview to guide future research and clinical management strategies for leprosy reactions.
