Unequal Burdens: Exploring Racial Differences in Sarcoidosis-Related Deaths Due to Pulmonary Hypertension Versus Fibrosis in the United States (1999-2023)

Key Points

This research aims to analyze racial differences in mortality rates among patients with sarcoidosis related to pulmonary causes of death.
Conducted a retrospective repeated cross-sectional study
Utilized CDC WONDER database for death certificate data
Analyzed mortality trends in sarcoidosis from 1999 to 2023
24,156 pulmonary deaths with comorbid sarcoidosis identified
Age-adjusted mortality rate increased from 2.7 to 4.8 per million from 1999 to 2023
70% of deaths attributed to pulmonary fibrosis and hypertension
Black individuals more likely to die from pulmonary hypertension at 37.3%
White individuals primarily died from pulmonary fibrosis at 52.8%

Abstract

Introduction Sarcoidosis disproportionately affects Black Americans, who report a higher incidence (17.8 per 100,000) compared to White Americans (8.1 per 100,000) and also experience greater disease severity, leading to an overall worse prognosis. Despite these trends, racial differences in cause-specific mortality among patients with sarcoidosis remain unexplored. In light of this, we aimed to assess longitudinal trends in mortality rates attributed to pulmonary causes of death among individuals with comorbid sarcoidosis. Methods We conducted a retrospective repeated cross-sectional study to determine the cause of death attributed to pulmonary deaths with comorbid sarcoidosis in the United States from 1999 to 2023. The data were obtained from the Centers for Disease Control and Prevention’s Wide Ranging Online Data for Epidemiologic Research (CDC WONDER) database, which includes the underlying and contributing causes of death from all death certificates in the United States. Results Of the 24,156 pulmonary deaths with comorbid sarcoidosis identified, 61.1% were women, and nearly 50% were aged 55-74 years. The age-adjusted mortality rate (AAMR) increased from 2.7 (95% confidence interval (CI): 2.5-3.0) per million in 1999 to 4.8 (95% CI: 4.5-5.1) in 2023. The annual percentage change (APC) was +1.1% (95% CI: 0.85-1.35) from 2001 to 2018, with a marked rise from 2018 to 2020 (APC: +10.36%, 95% CI: 4.50-16.54). Pulmonary fibrosis (PF) and pulmonary hypertension (PH) constituted 70% of pulmonary deaths with sarcoidosis. When stratified by race, Black individuals are more likely to die from PH (37.3%), with a greater burden in Black women (40.5%). In contrast, White individuals most commonly died from pulmonary fibrosis (PF) (52.8%). Conclusions Pulmonary deaths in sarcoidosis have increased over the past two decades, with racial disparities evident in underlying phenotypes. Black individuals, especially Black women, are more likely to die from PH, while White individuals disproportionately die from fibrosis. These findings highlight the importance of phenotype-specific screening strategies and equity-focused clinical interventions.
