Abstract:
We hypothesized that the large global variations in the prevalence of macrolide resistance in Treponema pallidum are related to differences in population-level macrolide consumption. The hypothesis was tested by, at a country-level, regressing the peak prevalence of macrolide resistance against the national macrolide consumption in the year prior to this, controlling for the year of the resistance prevalence estimate. A strong association was found between the per capita consumption of macrolides and macrolide resistance (coefficient 0.7, 95 % confidence interval 0.2-0.12, P=0.009).
Insights
Global macrolide consumption strongly correlates with macrolide resistance in Treponema pallidum. Higher antibiotic use in populations is linked to increased resistance, impacting public health strategies.
Area of Science:
- Microbiology
- Epidemiology
- Public Health
Background:
- Macrolide resistance in Treponema pallidum shows significant global variation.
- Understanding the drivers of this resistance is crucial for effective treatment and control.
Purpose of the Study:
- To investigate the relationship between population-level macrolide consumption and the prevalence of macrolide resistance in Treponema pallidum.
Main Methods:
- A country-level regression analysis was performed.
- Peak macrolide resistance prevalence was regressed against national macrolide consumption in the preceding year.
- The year of the resistance prevalence estimate was included as a control variable.
Main Results:
- A significant positive association was found between per capita macrolide consumption and macrolide resistance.
- The coefficient was 0.7 (95% CI: 0.2-0.12, P=0.009).
Conclusions:
- Population-level macrolide consumption is a significant factor contributing to global variations in Treponema pallidum macrolide resistance.
- This finding has implications for antibiotic stewardship and infectious disease management.
