BACKGROUND: The association between sepsis and non-infectious respiratory diseases is well-documented, yet the specific causal link between the two remains unclear. In order to explore this relationship further, we employed a Mendelian randomization (MR) analysis utilizing data from the UK Biobank and FinnGen Biobank.
METHODS: We analyzed the summary statistics of a genome-wide association study (GWAS) summary statistics for chronic obstructive pulmonary disease (COPD), asthma, pulmonary embolism (PE), idiopathic pulmonary fibrosis (IPF), obstructive sleep apnea (OSA), lung cancer, sepsis, and sepsis-related mortality. We employed the inverse-variance weighted (IVW) method and four additional MR methods. Heterogeneity and horizontal pleiotropy were assessed using the Cochrane's Q test, MR-Egger intercept, and MR-PRESSO test. A sensitivity analysis was also performed.
RESULTS: MR analysis showed associations between COPD and lung cancer with increased sepsis risk (odds ratio (OR)IVW 1.138, P = 0.006; (OR)IVW 1.123, P = 0.031; respectively) and sepsis mortality ((OR)IVW 1.350, P = 0.022; (OR)IVW 1.312, P = 0.022; respectively). Asthma exhibited a potential protective effect against sepsis mortality((OR)IVW = 0.300, P = 0.039), while PE demonstrated a risk effect ((OR)IVW = 1.148, P = 0.032). No causal association was observed between asthma, PE, and sepsis (P > 0.05). IPF and OSA were not significantly associated with sepsis or sepsis-related mortality (P > 0.05). Heterogeneity and horizontal pleiotropy were not evident for asthma or lung cancer (P > 0.05). However, horizontal pleiotropy was suggested for COPD by the MR-Egger regression (P < 0.05), but not by the MR-PRESSO test (P > 0.05). IPF and OSA were not significantly associated with sepsis or sepsis-related mortality (P > 0.05).
CONCLUSIONS: Our MR analysis offers new insights into potential links between noninfectious respiratory diseases and the risk of sepsis. However, additional investigation into the underlying mechanisms and clinical studies are necessary to confirm these findings.
