Historically inside the purview of rheumatology, gout can appropriately be managed by nephrologists for sufferers with persistent kidney illness, based on specialists who spoke with Healio | Nephrology Information & Points.
“It’s affordable for nephrologists to handle gout,” Tuhina Neogi, MD, PhD, chief of rheumatology at Boston Medical Middle, professor of epidemiology at Boston College College of Public Well being and part chief of rheumatology at Boston College Chobanian & Avedisian College of Medication, advised Healio. “For some sufferers, their nephrologist successfully is functioning as their major care doctor. Sufferers usually have monitoring labs obtained by their nephrologist, so including a urate stage for monitoring might be effectively finished with the identical blood draw. After all, as for any doctor managing gout, an analysis of medical illness exercise and adequacy of [treatment] would have to be finished by the nephrologist.”

Nissreen Elfadawy, MD, MS, FASN, FAST, medical assistant professor at Case Western Reserve College and a nephrologist at Geauga Medical Middle – College Hospitals of Cleveland, and Eldrid Baez, MD, a medical nephrologist at Dallas Renal Group, advised Healio they routinely handle sufferers with CKD and gout, and different nephrologists are additionally prone to see these sufferers.
About 23% of sufferers with CKD even have gout; 36% of these might have undiagnosed gout and 13% have un-controlled illness, based on knowledge revealed in Gout, Urate, and Crystal Deposition Illness in 2024. Within the examine, the prevalence of gout was highest amongst sufferers with CKD phases 3b and 4. Though not all sufferers with gout have kidney illness, they do have a 29% increased threat for creating superior CKD in contrast with sufferers with out gout, and their threat for end-stage kidney illness is elevated by 213%, based on knowledge revealed in BMJ Open in 2019.
Along with ache and disfigurement, gout can have severe penalties for sufferers with CKD. As Healio beforehand reported, amongst sufferers on hemodialysis, those that developed gout have been 6% much less prone to be wait-listed for a kidney transplant than these with out gout, based on knowledge introduced on the Nationwide Kidney Basis Spring Scientific Conferences in April.
CKD and gout connection
Gout begins with the kidney, based on Elfadawy. Usually functioning kidneys filter uric acid from the blood and remove it by urine. If serum ranges of uric acid rise excessive sufficient, crystals can type and accumulate in joints. This causes ache and irritation and, over time, may end up in tophi.
Not all individuals with hyperuricemia have gout, and never all sufferers with gout have kidney dysfunction. Some individuals might produce extra uric acid that can not be adequately eradicated by their wholesome kidneys.
“We all know that [with gout] the blood isn’t being filtered successfully. Now does it rise to the purpose of being ‘kidney illness’? Not essentially,” Baez stated. “There are some individuals who, by their genetics, are simply vulnerable to a lot increased uric acid ranges.”

Equally, not all sufferers with kidney dysfunction will develop gout.
Nevertheless, “the decrease the kidney perform is, the upper the danger for gout growth,” Elfadawy stated. “That’s why we see numerous gout instances in superior persistent kidney illness sufferers, particularly CKD phases 4 and 5.”
Sufferers with ESKD utilizing dialysis usually expertise much less hyperuricemia and fewer gout flares as a result of the dialysis machine filters out uric acid.
The connection between gout and kidney illness goes each methods, based on Baez. Whereas CKD can result in excessive uric acid ranges, hyperuricemia can worsen CKD.
“What we didn’t know till we had extra superior imaging research is that the uric acid is being deposited all through the physique. It permeates muscle, bones, ligaments and tendons, and connective tissue, inflicting harm. There are methods wherein excessive deposits of uric acid can have an effect on the guts and its tissues and result in types of coronary heart illness,” Baez stated.
The identical is true for the kidneys.
“Kidney illness can result in gout — to the buildup of uric acid — and that in flip can worsen the kidney illness itself,” Baez stated.
Treating gout with CKD
Treating gout in sufferers with CKD might be tough as therapies for both illness can worsen the opposite.
“No matter we do for persistent kidney illness can worsen gout, and no matter we do for gout can worsen persistent kidney illness,” Elfadawy stated.
For instance, sufferers with CKD are sometimes prescribed diuretics for comorbid hypertension, which interferes with the elimination of uric acid, Elfadawy stated. Equally, NSAIDs are really helpful for gout ache however can worsen kidney perform or trigger AKI and due to this fact are contraindicated in CKD. Actually, sufferers with gout are sometimes referred to a nephrologist for worsening kidney perform due to make use of of NSAIDs as a part of gout administration, she stated.
Administration of gout is considerably the identical whether or not a affected person additionally has CKD, based on administration steering co-written by Neogi and revealed within the American Journal of Kidney Ailments in 2017:
- Decrease serum uric acid with medicine to under 6 mg/dL or to under 5 mg/dL for sufferers with tophi.
- Use an anti-inflammatory drug, corresponding to colchicine, for prophylaxis of gout flares.
- Deal with gout flares with an anti-inflammatory drug, corresponding to colchicine or glucocorticoids; and
- Make weight loss plan and way of life changes.
First-line drugs for decreasing uric acid embrace the oral xanthine oxidase inhibitors allopurinol and febuxo-stat; IV pegloticase (Krystexxa, Amgen) can be utilized in superior CKD with extreme gout, however this biologic agent isn’t really helpful for first-line therapy, based on the 2020 gout administration guideline from the American School of Rheumatology.
Neogi cautions nephrologists treating gout that “renal-dosing” of allopurinol — adjusting the dose based on creatinine clearance worth — isn’t really helpful. “Quite a few research have demonstrated that it doesn’t lower threat of allopurinol hypersensitivity syndrome, and as a substitute, it contributes to insufficient administration of gout,” she stated. “Moreover, research have additionally demonstrated that allopurinol might be elevated above 300 mg safely with monitoring, even amongst individuals with renal insufficiency.”
Neogi additionally talked about a number of cautions when prescribing colchicine for prophylaxis or therapy of flares for pa-tients with CKD. Colchicine shouldn’t be used with robust cytochrome P450 3A4 inhibitors or P-glycoprotein in-hibitors, corresponding to clarithromycin, ketoconazole, grapefruit juice, diltiazem and verapamil, she stated. Colchicine must be used with warning for sufferers taking statins resulting from neuromyotoxicity dangers.
Who ought to handle gout
When nephrologists handle gout, they deal with the basis reason behind the illness whereas specializing in preserving kidney perform, Baez stated.
“Frankly, even recognizing that hyperlink between gout and kidney illness is one thing many medical suppliers weren’t taught by their coaching in medical faculty or in residency,” Baez stated. “If we don’t perceive an issue, it’s onerous to repair it.
“The wrestle for us as nephrologists is that a lot of the medical neighborhood thinks harm to the kidney is irre-versible, that when we’ve misplaced filtering perform there’s no approach to get it again,” he stated. “However happily, that’s now not the case. We at the moment are capable of not solely halt the development of persistent kidney illness with medical remedy, however in lots of instances reverse a few of that harm.”
Neogi stated rheumatologists ought to refer sufferers with gout and renal insufficiency to a nephrologist “to allow optimization of kidney well being, particularly to work up and tackle different contributors to declines in renal perform.”
On the whole, although, rheumatologists, nephrologists and PCPs are all effectively geared up to deal with gout, Elfadawy stated.
With shortages of nephrologists and rheumatologists, major care is usually the primary place a affected person with gout is seen. PCPs can appropriately educate sufferers about each gout and CKD, oversee way of life modifications and prescribe first-line therapies. They need to check with a specialist for escalating remedy in extreme instances, she stated.
