VOLUME | MAR 2022 Antibiotic Treatment of Leptospirosis Linked to Lower Risk of Dementia

Imagine your body is a bustling city, with different parts working together to keep everything running smoothly. In this study, scientists investigated the relationship between leptospirosis, a bacterial infection, and dementia, a condition that affects memory and thinking abilities. Using a national database from Taiwan, they followed over 1,400 individuals for 16 years to see if there was a connection. They found that those with leptospirosis had a higher risk of developing dementia compared to a control group. However, here comes the exciting part! When the researchers looked closer and focused on those who received antibiotic treatment for leptospirosis, they discovered something incredible: these individuals had a reduced risk of dementia! It’s like having a superhero antibiotic swoop in and save the day by protecting against dementia. While this study shows a promising link, more research is needed to uncover the underlying mechanisms. So, grab your lab coat and dive into the realm of science to learn more about this fascinating connection!

BackgroundTo explore the association between leptospirosis, the risk of dementia, and the potential protective role of antibiotic treatment.MethodsWe conducted a retrospective cohort nationwide, population-based study, from Taiwan’s National Health Insurance Research Database (NHIRD). We enrolled 1,428 subjects aged 50 years or above, in the index year of 2000, which included those retrieved from the NHIRD record. Dementia diagnosis and incidence over 16 years follow-up was retrieved from the NHIRD records. The Fine and Gray survival analysis was used to determine the risk of dementia, and the results were presented as a sub-distribution hazard ratio (SHR) with a 95% confidence interval.ResultsIn the study period, 43 of the 357 leptospirosis patients developed dementia, as compared to 103 of the control group (930.90 vs. 732.49 per 105 person-years). By the Fine and Gray survival analysis, the leptospirosis was associated with the risk of dementia, and the adjusted SHR was 1.357 (95% confidence interval [CI]: 1.213–1.519, P < 0.001), across 16-year of the follow-up period. To exclude the protopathic bias, the sensitivity analysis was conducted. This analysis revealed that the leptospirosis was associated with the increased risk of dementia, even after excluding the dementia diagnosis within the first year (adjusted SHR = 1.246, 95%CI: 1.114–1.395, P < 0.001) or within the first 5 years (adjusted SHR = 1.079, 95%CI: 1.023–1.152, P = 0.028), antibiotic treatment for leptospirosis was associated with the reduced risk of dementia (P = 0.001).ConclusionLeptospirosis was associated with an increased risk for dementia, and antibiotic treatment was associated with a reduced risk. Further research will be necessary to explore the underlying mechanisms of this association.
