Kidney damage relates to agonal bacteremia: a single-center retrospective study.
Background: Agonal bacteremia, diagnosed with postmortem positive blood culture results, is considered a possible contributing factor to death. We hypothesized that some premortem organ damage, such as kidney damage, can enhance agonal bacteremia.
Methods: We performed a postmortem blood and alveolar fluid culture study in 30 cadavers and evaluated the relationship between blood culture results and clinical parameters, including organ damage (brain, heart, lung, kidney, liver and gastrointestinal tract).
Results: A total of 23 cases (76.7%) were positive for blood culture; the number of cultured species was one in 12 cases, two in 7 cases, and three in 4 cases. The ratio of agonal bacteremia was significantly higher in patients with heart damage (100%, n = 13) and those with kidney damage (end-stage kidney damage, acute kidney injury, obstructive kidney failure, or metastatic kidney tumours) (100%, n = 13). The mean number of cultured species was 0.67 ± 0.98 in heart or kidney damage, 1.40 ± 0.55 in heart damage only, 1.40 ± 0.55 in kidney damage only, and 2.00 ± 0.93 in heart and kidney damage. As the number of damaged organs increased (0 organs, no heart/kidney damage; 1 organ, heart or kidney damage; and 2 organs, heart and kidney damage), the mean number of cultured species increased significantly (p for trend = 0.001964).
Conclusion: Premortem kidney damage relates to agonal bacteremia.
期刊介绍：
Clinical and Experimental Nephrology is a peer-reviewed monthly journal, officially published by the Japanese Society of Nephrology (JSN) to provide an international forum for the discussion of research and issues relating to the study of nephrology. Out of respect for the founders of the JSN, the title of this journal uses the term “nephrology,” a word created and brought into use with the establishment of the JSN (Japanese Journal of Nephrology, Vol. 2, No. 1, 1960). The journal publishes articles on all aspects of nephrology, including basic, experimental, and clinical research, so as to share the latest research findings and ideas not only with members of the JSN, but with all researchers who wish to contribute to a better understanding of recent advances in nephrology. The journal is unique in that it introduces to an international readership original reports from Japan and also the clinical standards discussed and agreed by JSN.
