Hermansky-Pudlak Syndrome.

Area of Science:

• Genetics and rare diseases
• Pulmonology
• Hematology

Background:

• Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder.
• Key features include oculocutaneous albinism, platelet dysfunction, and bleeding diathesis.
• Certain subtypes present with progressive fibrosing interstitial lung disease (ILD), inflammatory bowel disease, and immunodeficiency.

Purpose of the Study:

• To highlight the variable manifestations of HPS.
• To emphasize the need for early recognition and diagnosis to prevent complications.
• To underscore the critical management strategies for HPS-1 and HPS-4 patients at risk of pulmonary fibrosis.

Main Methods:

• Literature review of HPS manifestations and outcomes.
• Analysis of clinical data regarding disease progression in HPS subtypes.
• Review of current management guidelines for interstitial lung disease in HPS.

Main Results:

• Progressive pulmonary fibrosis and respiratory failure are the primary causes of mortality in HPS-1 and HPS-4.
• Early detection of ILD and consistent lung function monitoring are crucial.
• Timely intervention for pulmonary fibrosis and consideration for lung transplantation are essential.

Conclusions:

• Hermansky-Pudlak syndrome requires comprehensive management tailored to its specific manifestations.
• Proactive surveillance and treatment of interstitial lung disease are critical for improving survival in HPS-1 and HPS-4.
• Multidisciplinary care, including early referral for lung transplantation, is vital for patients with progressive pulmonary fibrosis.
