| Abstract |
Hypertension is highly prevalent in patients with rheumatoid arthritis (RA). In other populations, high sodium (Na+) and low potassium (K+) intake are associated with an increased risk of hypertension, and in animal models, a high salt intake exacerbated arthritis. Patients with RA have many comorbidities associated with salt sensitivity, but their salt intake and its relationship to blood pressure and inflammation is unknown. Using the Kawasaki formula, Na+ and K+ urinary excretion (reflecting intake) was estimated in 166 patients with RA and 92 controls, frequency matched for age, sex, and race. Inflammatory markers and disease activity were measured in RA patients. We tested the associations between blood pressure and Na+ and K+ excretion. Estimated 24-h Na+ excretion was similarly high in both RA (median [IQR] 5.1 g, [3.9-6.6 g]) and controls (4.9 g, [4.0-6.5 g]), p = 0.9, despite higher rates of hypertension in RA (54 vs. 39%, p = 0.03). The Na+:K+ excretion ratio was significantly higher in RA (2.0 [1.6-2.4]) vs. 1.7 [1.5-2.1]), p = 0.02] compared to controls. In RA, a lower K+ excretion was inversely correlated with diastolic blood pressure (adjusted β = - 1.79, p = 0.04). There was no significant association between Na+ or K+ excretion and inflammatory markers. Despite a similar Na+ excretion, patients with RA had higher rates of hypertension than controls, a finding compatible with increased salt sensitivity. Patients with RA had a lower Na+:K+ excretion ratio than controls, and lower K+ excretion was associated with higher diastolic blood pressure in RA. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 April 2018.
All research outputs
#20,480,611
of 23,041,514 outputs
Outputs from Clinical Rheumatology
#2,666
of 3,043 outputs
Outputs of similar age
#374,819
of 439,402 outputs
Outputs of similar age from Clinical Rheumatology
#44
of 58 outputs
Altmetric has tracked 23,041,514 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,043 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.9. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 439,402 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 58 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
