Insights
Diabetes significantly increases stroke risk in women with gout. Managing diabetes and other gout comorbidities early is crucial for reducing future stroke incidence in this population.
Area of Science:
- Rheumatology
- Cardiovascular Medicine
- Epidemiology
Background:
- Gout comorbidities and their sex-specific clinical features are complex.
- Limited research exists on gout comorbidities specifically within the female population.
- Understanding comorbidity trajectories is vital for managing gout's impact.
Purpose of the Study:
- To compare comorbidity aggregation and trajectories in female and male gout patients.
- To investigate the consequences of these comorbidities, particularly stroke risk.
- To identify sex differences in gout comorbidity patterns.
Main Methods:
- Prospective cohort study utilizing Taiwan's National Health Insurance Research Database (2000-2009).
- Analysis of cardiovascular disease, hyperlipidemia, hypertension, diabetes mellitus (DM), and chronic kidney disease.
- Latent trajectory analysis to determine comorbidity transition patterns and cumulative stroke incidence (2000-2010).
Main Results:
- Five distinct comorbidity cluster transition (CT) phenotypes were identified in both sexes.
- Female gout patients in CT2 predominantly had DM, correlating with a higher stroke risk.
- Specific comorbidity patterns were observed, with varying persistence and transitions over time.
Conclusions:
- Diabetes mellitus is a significant risk factor for stroke development in female gout patients.
- Proactive assessment and management of gout comorbidities, especially DM, can mitigate stroke risk.
- This study highlights the importance of sex-specific considerations in gout management.
Objective:
Gout-related comorbidities are intricate and its clinical features may demonstrate sex difference; however, few studies have evaluated the links between comorbidities and gout in a female population. The objectives of this study were to compare the aggregation and transitive trajectories of comorbidities of gout, and their consequences in female and male gout populations.
Methods:
A prospective cohort study was conducted using data from the Taiwan National Health Insurance Research Database. A female and male gout population were followed up from 2000 to 2009 to identify the comorbidities of cardiovascular disease, hyperlipidemia, hypertension, diabetes mellitus (DM) and chronic kidney disease. The cumulative incidence of stroke from 2000 to 2010 was examined. A latent trajectory analysis was used to determine the transitive trajectories of the comorbidities of gout.
Results:
Both female and male patients with gout had five risk cluster transition (CT) phenotypes of comorbidities within 10-year follow-up: CT1 and CT2, with various persistent comorbidities; CT3, with few persistent comorbidities; and CT4 and CT5, with transfer to cluster 1 from other clusters. The female participants in CT2 predominantly experienced DM and were associated with significantly increased risk of developing stroke.
Conclusion:
Diabetes is a notable risk factor for the development of stroke in female patients with gout. Early assessment and management for the comorbidities of gout, particularly in DM, would effectively reduce future stroke risk in female gout population.
