Background
Individuals with chronic kidney disease have increased risk of infection and decreased serologic response to pneumococcal vaccination. The comparative effectiveness of pneumococcal vaccination in individuals with and without CKD is unknown.
Methods
Test negative design of all hospitalized adults at Geisinger Health System with a pneumococcal urine antigen test from 2016 – 2021. Cases were defined by a composite of positive urine test, body fluid culture, or diagnostic code for pneumococcal disease. Controls were those who tested negative. We used doubly robust estimation by controlling for the probability of receiving a pneumococcal vaccine using inverse probability of treatment weighting as well as multivariable logistic regression to estimate the odds ratios (ORs) of receiving vaccination between cases and controls. VE was calculated as 1-OR*100.
Results
We identified a total of 180 cases and 3,889 controls (mean age 69 years, female 48%, White 97%, mean eGFR 71 mL/min/1.73 m2). The receipt of PCV13, PPSV23, and both was seen in 42%, 76%, and 39% among cases, and 51%, 78%, and 48% among controls. In the overall population, the adjusted PCV13 VE was 36% (95% CI 2.6 – 58%), and combination PCV13 & PPSV23 was 40% (13 - 59%); but not evident for PPSV23 (VE -16% [95% CI -93 – 31%]). When stratified by eGFR, the adjusted PCV13 VE was consistent in eGFR ≥60 (VE 38% [95% CI -5.2 - 64%]) and 30-59 ml/min/1.73m2 (VE 57% [95% CI 11 – 79%]) without significant interaction; but not calculable for eGFR <30 due to small sample size.
Conclusion
Receipt of PCV13 was associated with reduced risk of pneumococcal diseases in individuals with reduced kidney function.
