Insights
One in five stroke survivors in Ghana have chronic kidney disease (CKD). This study identified age, male sex, rural residence, and antihypertensive use as key risk factors for CKD in this population.
Area of Science:
- Nephrology
- Neurology
- Public Health
Background:
- Chronic kidney disease (CKD) is linked to adverse outcomes in stroke survivors.
- Stroke and CKD incidence are rising in Africa, yet CKD burden in stroke survivors remains understudied.
- This research addresses the knowledge gap in sub-Saharan Africa.
Purpose of the Study:
- To determine the prevalence of CKD among stroke survivors in Ghana.
- To identify factors associated with CKD in this patient group.
- To stratify findings by primary stroke type.
Main Methods:
- Prospective data collection from stroke survivors at a Ghanaian outpatient clinic (Jan 2018-Mar 2020).
- Estimated glomerular filtration rate (eGFR) calculated using CKD-EPI formula; CKD defined as eGFR <60ml/min.
- Multiple logistic regression used to identify factors associated with CKD.
Main Results:
- A prevalence of 21.0% (159/759) for CKD was observed among stroke survivors.
- Significant CKD associations included: higher age (per decile rise), male sex, rural dwelling, prior antihypertensive use, and number of antihypertensive classes.
- Individuals with CKD were significantly older (61.6 vs 57.5 years).
Conclusions:
- Approximately 21% of stroke survivors in this Ghanaian cohort exhibit signs of CKD.
- Interventions targeting blood pressure management and rural populations are recommended.
- Addressing CKD in stroke survivors may reduce the risk of poor health outcomes.
Background:
Chronic kidney disease (CKD) is associated with poor outcomes among stroke survivors. In Africa, where both stroke and CKD incidence rates are escalating, little, if anything, is known about the burden of CKD among stroke survivors.
Objective:
To assess the frequency and factors associated with CKD among stroke survivors by primary stroke types.
Methods:
Stroke registry data were prospectively collected on consecutively encountered stroke survivors seen at an out-patient clinic in Ghana between January 2018 and March 2020. We calculated estimated glomerular filtration rate (eGFR) using the CKD-EPI formula and defined CKD as eGFR <60ml/min. Factors associated with CKD were assessed using multiple logistic regression modelling.
Results:
Among 759 stroke survivors, 159 had CKD giving a prevalence of 21.0% (95%CI: 18.1% - 23.8%). The mean age of those with CKD was 61.6 ± 14.2 years compared with 57.5 ± 13.6 years, p=0.0007 among those without CKD. Five factors remained significantly associated with CKD with the following adjusted odds ratio (aOR and 95% CI). Age per decile rise 1.30 (1.13-1.50), male sex 1.99 (1.36-2.93), rural dwelling residence 1.95 (1.06-3.59), prior use of antihypertensive meds before index stroke onset 1.63 (1.08-2.47), and number of antihypertensive medication classes 1.25 (1.06-1.45).
Conclusion:
1 in 5 stroke survivors have evidence of chronic kidney disease in this Ghanaian study. Targeted interventions focusing on optimizing blood pressure control and rural dwellers may mitigate their risk for adverse outcomes.
