GERD increases susceptibility to nontuberculous mycobacterial pulmonary disease according to a recent study published in the Chest.
Gastroesophageal reflux disease (GERD) is a common comorbidity of nontuberculous mycobacteria (NTM) pulmonary disease (PD). Although GERD is associated with more symptoms and severe disease in patients with NTM PD, whether GERD is associated with an increased risk of NTM PD developing is unknown.
Research Questions:
Does GERD influence the development of NTM PD?
Are there any factors associated with an increased risk of NTM PD among patients with GERD?
What is the impact of NTM PD on the health-care use of patients with GERD?
Data from the Korean National Health Insurance Service National Sample Cohort between 2002 and 2015 were used. The incidence and risk of NTM PD were compared between patients with GERD (GERD cohort; n = 17,424) and patients matched for age, sex, type of insurance, and Charlson Comorbidity Index (matched cohort; n = 69,696). Using the GERD cohort, the factors associated with incident NTM PD also were evaluated.
Results:
- During a median follow-up duration of 5.1 years, the age- and sex-adjusted incidence of NTM PD was significantly higher in the GERD cohort with a subdistribution hazard ratio (HR) of 3.36
- Regarding risk factors associated with NTM PD, age of 60 years or older and bronchiectasis were associated with an increased risk of incident NTM PD in the GERD cohort.
- Compared with patients with GERD who did not demonstrate NTM PD, those with NTM PD showed higher all-cause and respiratory disease-related ED visits or hospitalizations.
GERD is associated with an increased incidence of NTM PD. Older age and bronchiectasis are risk factors for NTM PD in patients with GERD. NTM PD in patients with GERD is associated with increased health-care use.
