Case reportSuccessful Bilateral Lung Transplantation for Pulmonary Fibrosis Associated With the Hermansky-Pudlak Syndrome

Case report
A 38-year-old Puerto Rican man with interstitial lung disease was referred for lung transplantation evaluation. HPS was suspected from the presence of oculocutaneous albinism and pulmonary fibrosis confirmed by video-assisted thoracoscopic lung biopsy. Neither this procedure nor 2 prior orthopedic surgeries were associated with excessive bleeding.
The patient’s oxygen saturation of hemoglobin while breathing 1 liter of oxygen at rest was 90% and decreased to 73% with minimal exertion. Pulmonary
Discussion
We successfully performed bilateral lung transplantation in a patient with Hermansky-Pudlak syndrome, a disease characterized by a bleeding diathesis and pulmonary fibrosis. In the past, several issues have prevented HPS patients from undergoing lung transplantation. First, the bleeding diathesis of HPS has been considered a contraindication to lung transplantation, as the absence of dense bodies in HPS patients’ platelets impedes the normal secondary aggregation response, resulting in bruising

Lung transplantation was first utilized as a treatment for Hermansky-Pudlak syndrome in 2005, when a patient with advanced pulmonary fibrosis received a bilateral lung transplant at Columbia University Medical Center in New York City [30]. This patient carried the same homozygous HPS1 16-bp deletion as our patient and was also of Puerto Rican ethnicity.

2021, European Journal of Medical GeneticsCitation Excerpt :No drugs have been approved for clinical treatment so far. Some patients with HPS who experienced severe pulmonary fibrosis received lung transplantation; however, many challenges prevail in treating these patients in clinical practice (Lederer et al., 2005; Seward and Gahl, 2013; El-Chemaly et al., 2018). Therefore, establishing a reliable HPS diagnosis is crucial to identify HPS subtypes and formulate a long-term clinical plan to maintain candidates for lung transplantation.

2018, Molecular Genetics and MetabolismCitation Excerpt :The prognosis of patients with HPS pulmonary fibrosis is poor, and approved medical therapy is not available. Patients with end-stage HPS pulmonary fibrosis succumb to progressive ventilatory failure unless they undergo lung transplantation [17, 18]. Pirfenidone, an oral anti-fibrotic drug, was investigated at the National Institutes of Health (NIH) Clinical Center as treatment for HPS pulmonary fibrosis in two clinical trials [19, 20].
