Hypertension, renal function and gout
Insights
Hypertension affects 18% of untreated gout patients, a lower rate than expected. Hypertensive gout patients showed higher body weight and reduced glomerular filtration rate compared to controls.
Area of Science:
- Nephrology
- Rheumatology
- Cardiology
Background:
- Gout is a common condition associated with metabolic disturbances.
- Hypertension is a known comorbidity in patients with gout.
- Previous studies suggested a higher prevalence of hypertension in gout patients.
Purpose of the Study:
- To determine the prevalence of hypertension in untreated gout patients.
- To compare clinical characteristics and renal function between hypertensive and normotensive gout patients, and normouricemic controls.
Main Methods:
- Cross-sectional study comparing three groups: untreated hypertensive gout patients, normotensive gout patients, and normouricemic patients.
- Assessment of clinical characteristics, including body weight.
- Evaluation of renal function, including glomerular filtration rate.
Main Results:
- Hypertension was identified in 18% of 65 untreated gout patients.
- Hypertensive gout patients exhibited significantly greater body weight compared to control groups.
- A significantly lower glomerular filtration rate was observed in hypertensive gout patients.
Conclusions:
- The prevalence of hypertension in this cohort of untreated gout patients was 18%.
- Hypertension in gout patients is associated with increased body weight and impaired renal function (reduced GFR).
- The complex interplay of factors makes a simple causal relationship between gout, hypertension, and renal impairment unlikely.
Abstract:
Hypertension was found in 18% of 65 patients with untreated gout, a lower prevalence than that previously reported. The clinical characteristics and renal function of these patients were compared with those of age matched groups of both normotensive gouty subjects and normouricaemic patients. The hypertensive patients had significantly greater body weights than their controls and also had a lower glomerular filtration rate. Other aspects of renal function were not significantly different between the three groups. The association of hypertension with gout and impaired renal function is complicated by many possible contributory factors and a simple cause and effect relationship is unlikely.
