ILD decreasing as cause of hospitalization, mortality in SSc
Hospital admission and mortality related to interstitial lung disease (ILD) in patients with systemic sclerosis (SSc) decreased over a 10-year period, according to a study. Infection, most often pneumonia, was the main cause of acute hospitalization and mortality.
In this retrospective analysis, all acute hospital admissions from a cohort of 95 patients with SSc from a single center over 10 years (2010-2020) were analyzed. During this time, the center treated 123 patients with SSc, 53 of whom required acute hospitalization for a total of 164 admissions.
Infectious disease was the most frequent reason for admission (27%), with the majority (70%) having pneumonia. Of the patients with pneumonia, 74% had SSc-associated ILD. Approximately 70% of patients admitted due to infection were immunosuppressed at the time of the hospitalization.
Other frequent causes for hospital admission included cardiac disease (16.5%), peripheral vascular disease (12.8%), pulmonary hypertension (9.8%), and ILD (9.1%).
Over the 10-year study period, admissions due to cardiac disease increased whereas, over the last 5 years of the study period, admissions due to ILD decreased.
There was an in-hospital mortality rate of 9%. Of the 14 patients that died, 36% were due to pneumonia, 21% due to heart failure, 21% due to neoplastic diseases, 14% due to pulmonary hypertension, and 7% due to ILD.
Gender, race, digital ulcers, cardiac dysfunction, ILD, and pulmonary hypertension were factors associated with acute admissions and mortality.
