Gout

LA JOLLA, CALIF. – Twelve years ago, an international task force of the European Alliance of Associations for Rheumatology (EULAR) released recommendations regarding nomenclature in calcium pyrophosphate deposition disease (CPPD), aiming to standardize the way the condition is described. “Pseudogout” was out, and “acute CPP crystal arthritis” was in, and a confusing array of multi-named phenotypes gained specific labels.

Since 2011, the nomenclature guidelines have been cited hundreds of times, but a new report finds that the medical literature mostly hasn’t followed the recommendations. The findings were released at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network (G-CAN), which is taking another stab at overhauling CPPD nomenclature.

“The objective is to uniform and standardize the labels of the disease, the disease elements, and the clinical states,” rheumatologist Charlotte Jauffret, MD, of the Catholic University of Lille (France), said in a presentation. CPPD is a widely underdiagnosed disease that’s worth the same efforts to standardize nomenclature as occurred in gout, she said.

As Dr. Jauffret explained, CPPD has a diversity of phenotypes in asymptomatic, acute, and chronic forms that pose challenges to diagnosis. “The same terms are used to depict different concepts, and some disease elements are depicted through different names,” she said.

Among other suggestions, the 2011 EULAR recommendations suggested that rheumatologists use the terms chronic CPP crystal inflammatory arthritis instead of “pseudo-rheumatoid arthritis,” osteoarthritis with CPPD, instead of “pseudo-osteoarthritis,” and severe joint degeneration instead of “pseudo-neuropathic joint disease.”

Later reports noted that terms such as CPPD and chondrocalcinosis are still wrongly used interchangeably and called for an international consensus on nomenclature, Dr. Jauffret said.

For the new report, Dr. Jauffret and colleagues examined 985 articles from 2000-2022. The guidelines were often not followed even after the release of the recommendations.

For example, 49% of relevant papers used the label “pseudogout” before 2011, and 43% did afterward. A total of 34% of relevant papers described CPPD as chondrocalcinosis prior to 2011, and 22% did afterward.

G-CAN’s next steps are to reach consensus on terminology through online and in-person meetings in 2024, Dr. Jauffret said.
 

Use of correct gout nomenclature labels improved

In a related presentation, rheumatologist Ellen Prendergast, MBChB, of Dunedin Hospital in New Zealand, reported the results of a newly published review of gout studies before and after G-CAN released consensus recommendations for gout nomenclature in 2019. “There has been improvement in the agreed labels in some areas, but there remains quite significant variability,” she said.

The review examined American College of Rheumatology and EULAR annual meeting abstracts: 596 from 2016-2017 and 392 from 2020-2021. Dr. Prendergast said researchers focused on abstracts instead of published studies in order to gain the most up-to-date understanding of nomenclature.

“Use of the agreed labels ‘urate’ and ‘gout flare’ increased between the two periods. There were 219 of 383 (57.2%) abstracts with the agreed label ‘urate’ in 2016-2017, compared with 164 of 232 (70.7%) in 2020-2021 (P = .001),” the researchers reported. “There were 60 of 175 (34.3%) abstracts with the agreed label ‘gout flare’ in 2016-2017, compared with 57 of 109 (52.3%) in 2020-2021 (P = .003).”

And the use of the term “chronic gout,” which the guidelines recommend against, fell from 29 of 596 (4.9%) abstracts in 2016-2017 to 8 of 392 (2.0%) abstracts in 2020-2021 (P = .02).

LA JOLLA, Calif. – A new analysis suggests that it may not be necessary to delay urate-lowering therapy (ULT) in gout flares, and a study warns of the potential heightened risk of peripheral arterial disease (PAD) in gout.

The reports were released at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network (G-CAN).

The urate-lowering report, a systematic review and meta-analysis, suggests that the use of ULT during a gout flare “does not affect flare severity nor the duration of the flare or risk of recurrence in the subsequent month,” lead author Vicky Tai, MBChB, of the University of Auckland (New Zealand), said in a presentation.

She noted that there’s ongoing debate about whether ULT should be delayed until a week or two after gout flares subside to avoid their return. “This is reflected in guidelines on gout management, which have provided inconsistent recommendations on the issue,” Dr. Tai said.

As she noted, the American College of Rheumatology’s 2020 gout guidelines conditionally recommended starting ULT during gout flares – and not afterward – if it’s indicated. (The guidelines also conditionally recommend against ULT in a first gout flare, however, with a few exceptions.)

The British Society for Rheumatology’s 2017 gout guidelines suggested waiting until flares have settled down and “the patient was no longer in pain,” although ULT may be started in patients with frequent attacks. The European Alliance of Associations for Rheumatology’s gout guidelines from 2016 didn’t address timing, Dr. Tai said.

For the new analysis, Dr. Tai and colleagues examined six randomized studies from the United States (two), China (two), Taiwan (one), and Thailand (one) that examined the use of allopurinol (three studies), febuxostat (two studies), and probenecid (one). The studies, dated from 2012 to 2023, randomized 226 subjects with gout to early initiation of ULT vs. 219 who received placebo or delayed ULT. Subjects were tracked for a median of 28 days (15 days to 12 weeks).

Three of the studies were deemed to have high risk of bias.

There were no differences in patient-rated pain scores at various time points, duration of gout flares (examined in three studies), or recurrence of gout flares (examined in four studies).

“Other outcomes of interest, including long-term adherence, time to achieve target serum urate, and patient satisfaction with treatment, were not examined,” Dr. Tai said. “Adverse events were similar between groups.”

She cautioned that the sample sizes are small, and the findings may not be applicable to patients with tophaceous gout or comorbid renal disease.

A similar meta-analysis published in 2022 examined five studies (including three of those in the new analysis); among the five was one study from 1987 that examined azapropazone and indomethacin plus allopurinol. The review found “that initiation of ULT during an acute gout flare did not prolong the duration of acute flares.”
 

Risk for PAD

In the other study, researchers raised an alarm after finding a high rate of PAD in patients with gout regardless of whether they also had diabetes, which is a known risk factor for PAD. “Our data suggest that gout is an underrecognized risk factor for PAD and indicates the importance of assessing for PAD in gout patients,” lead author Nicole Leung, MD, of NYU Langone Health, said in a presentation.

According to Dr. Leung, there’s little known about links between PAD and gout, although she highlighted a 2018 study that found that patients with obstructive coronary artery disease were more likely to have poor outcomes if they also developed gout after catheterization. She highlighted a 2022 study that found higher rates of lower-extremity amputations in patients with gout independent of cardiovascular disease and diabetes. However, she noted that a link to PAD is unclear, and the study found a link between gout and amputations that was independent of PAD.

Patients with gout, she added, are not routinely screened for PAD.

For the new retrospective, cross-sectional analysis, Dr. Leung and colleagues examined Veterans Administration data from 2014 to 2018 for 7.2 million patients. The population was largely male.

Of those, 140,862 (2.52%) – the control group – had no gout or diabetes. In comparison, 11,449 (5.56%) of 205,904 with gout but not diabetes had PAD, for a rate 2.2 times greater than the control group). PAD occurred in 101,582 (8.70%) of 1,168,138 with diabetes but not gout, giving a rate 3.2 times greater than the control group. The rate was highest among people with both gout and diabetes, at 9.97% (9,905 of 99,377), which is about four times greater than the control group.

The link between gout and PAD remained after adjustment for creatinine levels, age, gender, and body mass index. Diabetes was linked to a higher risk for PAD than was gout, and the effect of both conditions combined was “less than additive.” This “may suggest an overlap and pathophysiology between the two,” she said.

TOPLINE:

The prevalence of reported diagnosed arthritis in the United States is highest overall in older adults with comorbid chronic conditions.

METHODOLOGY:

• Researchers reviewed data from the National Health Interview Survey (NHIS) from 2019 to 2021 to update the prevalence of self-reported arthritis in the United States.
• The sample sizes for the 2019, 2020, and 2021 NHIS were 31,997, 21,153, and 29,482, with survey response rates of 59.1%, 48.9%, and 50.9%, respectively.
• The unadjusted and age-standardized prevalence estimates were calculated for adults aged 18 years and older and based on self-reported health and demographic data.

TAKEAWAY:

• Overall, arthritis was diagnosed in 53.2 million adults aged 18 years and older in the United States; of these, 88.3% were aged 45 years and older and 48.3% were 65 years and older.
• Age-standardized prevalence of arthritis was higher in women vs men and among veterans vs nonveterans (20.9% vs 16.3% and 24.2% vs 18.5%, respectively).
• When categorized by race, age-standardized prevalence of arthritis was higher among non-Hispanic White individuals, compared with Hispanic or Latino individuals or non-Hispanic Asian individuals (20.1%, 14.7%, and 10.3%, respectively).
• The prevalence of arthritis also was higher among individuals with self-reported diagnosis of chronic conditions including dementia, chronic obstructive pulmonary disease, stroke, heart disease, diabetes, and cancer than in those without these conditions; approximately half of adults aged 65 years and older with arthritis reported at least one of these conditions.

IN PRACTICE:

“These prevalence estimates can be used to guide public health policies and activities to increase equitable access to physical activity opportunities within the built environment and other community-based, arthritis-appropriate, evidence-based interventions,” the authors write.

SOURCE:

The study was led by Elizabeth A. Fallon, PhD, of the Centers for Disease Control and Prevention, Atlanta, Georgia. The data were published online in the CDC’s Morbidity and Mortality Weekly Report.  

LIMITATIONS:

The cross-sectional design prevented conclusions of causality between individual characteristics and arthritis diagnosis; other limitations included the reliance on self-reports, possible response bias, and the inability to calculate prevalence of arthritis subtypes. 

DISCLOSURES:

The study received no outside funding. The researchers had no financial conflicts to disclose.

• Overall, arthritis was diagnosed in 53.2 million adults aged 18 years and older in the United States; of these, 88.3% were aged 45 years and older and 48.3% were 65 years and older.
• Age-standardized prevalence of arthritis was higher in women vs men and among veterans vs nonveterans (20.9% vs 16.3% and 24.2% vs 18.5%, respectively).
• When categorized by race, age-standardized prevalence of arthritis was higher among non-Hispanic White individuals, compared with Hispanic or Latino individuals or non-Hispanic Asian individuals (20.1%, 14.7%, and 10.3%, respectively).
• The prevalence of arthritis also was higher among individuals with self-reported diagnosis of chronic conditions including dementia, chronic obstructive pulmonary disease, stroke, heart disease, diabetes, and cancer than in those without these conditions; approximately half of adults aged 65 years and older with arthritis reported at least one of these conditions.

IN PRACTICE:

“These prevalence estimates can be used to guide public health policies and activities to increase equitable access to physical activity opportunities within the built environment and other community-based, arthritis-appropriate, evidence-based interventions,” the authors write.

SOURCE:

The study was led by Elizabeth A. Fallon, PhD, of the Centers for Disease Control and Prevention, Atlanta, Georgia. The data were published online in the CDC’s Morbidity and Mortality Weekly Report.  

LIMITATIONS:

The cross-sectional design prevented conclusions of causality between individual characteristics and arthritis diagnosis; other limitations included the reliance on self-reports, possible response bias, and the inability to calculate prevalence of arthritis subtypes. 

DISCLOSURES:

The study received no outside funding. The researchers had no financial conflicts to disclose.

TOPLINE:

Matched cohort studies revealed infrequent adverse events (AEs) with either treatment, but the number needed to harm for any AE was more than three times higher with colchicine versus NSAIDs.

METHODOLOGY:

• The researchers conducted two matched retrospective cohort studies using the U.K. Clinical Practice Research Datalink and the Hospital Episode Statistics primary care datasets to compare AEs in adults initiating allopurinol for gout with and without colchicine or NSAID prophylaxis.
• For the study, 13,945 patients with gout who received colchicine were matched to 13,945 patients who received no prophylaxis. In addition, 25,980 patients with gout who received NSAIDs were matched to 25,980 who received no prophylaxis.
• The researchers used proportional hazard models to explore the associations between prophylaxis with either colchicine or NSAIDs and AEs.

TAKEAWAY:

• The incidence of most AEs was less than 200 per 10,000 patient-years, but the most common AE among patients given colchicine was diarrhea, with an incidence of 784.4 per 10,000 person-years, whereas the most common AE in those given NSAIDs was angina, with an incidence of 466.6 per 10,000 person-years.
• The number needed to harm in relation to any AE was 14.7 for colchicine, driven mainly by diarrhea, and 48.1 for NSAID.
• Compared with patients who started allopurinol without prophylaxis, those treated with colchicine were more likely to experience diarrhea, myocardial infarction, neuropathy, myalgia, and bone marrow suppression, whereas those treated with NSAIDs were more likely to experience angina, acute kidney injury, myocardial infarction, and peptic ulcer disease.
• Diarrhea, the most common AE, occurred in 17.9% of individuals who received colchicine.

IN PRACTICE:

“Our findings will provide much-needed information about the safety of flare prophylaxis that can inform treatment decisions and the choice between colchicine or NSAID for prophylaxis when initiating allopurinol, directly benefiting people with gout and their clinicians,” the authors write.

First author Edward Roddy, MD, of Keele (England) University, and colleagues published their report online in BMJ’s Annals of the Rheumatic Diseases.

LIMITATIONS:

The study identified gout based on clinical diagnosis in primary care and only considered AEs serious enough to merit consultation or hospitalization; other limitations included the observational design and lack of data on the use of over-the-counter NSAIDs.

DISCLOSURES:

The study was supported by the National Institute for Health and Care Research’s Research for Patient Benefit program. The researchers had no financial conflicts to disclose.

The use of colchicine prophylaxis during the process of up-titrating allopurinol slowly to reach target serum urate levels for patients with gout proved necessary to reduce the risk of flares in a randomized, double-blind, placebo-controlled noninferiority trial conducted by researchers in New Zealand.

Use of colchicine led to fewer flares during the first 6 months after initiating treatment with allopurinol, but when colchicine and placebo were stopped at 6 months, the number of flares rose, and there was no overall difference in the average number of flares between the placebo and colchicine groups over 12 months.

“Gout flares are common when starting urate-lowering therapy, although may be less frequent using the newer allopurinol ‘start-low, go-slow’ dose escalation strategy,” Lisa Stamp, MBChB, PhD, of the University of Otago, Christchurch, New Zealand, and colleagues write in Annals of the Rheumatic Diseases. “This study was undertaken to determine whether colchicine prophylaxis is required with the more gradual dose escalation of allopurinol to achieve target serum urate.”

The study was published online  in the BMJ.

The researchers randomly assigned 200 participants to receive colchicine 0.5 mg daily or placebo. At the same time, allopurinol 50 mg daily was initially given to those with an estimated glomerular filtration rate (eGFR) less than 60 mL/min/1.73 m2, and 100 mg daily was given to those with eGFR greater than or equal to 60 mL/min/1.73 m2; doses were increased monthly by 50 mg daily for those with eGFR less than 60 and by 100 mg daily for those with eGFR greater than or equal to 60 until the target urate level of less than 0.36 mmol/L (about < 6 mg/dL) was achieved. In total, 93% of patients were male, and 69% were White. Patients were enrolled from February 2019 through December 2021. The final study visit was in January 2023. Researchers tracked the mean number of patient-reported gout flares per month with a prespecified noninferiority margin of 0.12 gout flares/month. After the first 6 months, colchicine and placebo were stopped, and researchers continued to track outcomes up to month 12.

From baseline to 6 months, there were more gout flares per month in the placebo group (0.61) than in the colchicine group (0.35). From 6 to 12 months, there were more gout flares among patients who previously received colchicine, compared with those who received placebo. While 22.8% of patients in the colchicine group experienced flares at month 6, the following month – after stopping the drug – 41.2% experienced flares. For comparison, 30.8% of the placebo group experienced flares at month 6, and in month 7, 23.5% experienced flares. The spike in flares in the colchicine group began to decline after month 9.

Among the colchicine and placebo groups, reductions in serum urate at 6 and 12 months were similar, and mean serum urate levels declined below 0.36 mmol/L at 4 months and thereafter. Both groups reached a mean allopurinol dose of 280 mg/d at 6 months.

It is not clear what caused this rise in flares in the colchicine group, Stamp noted in an email to this news organization. Overall, there was no difference in the average number of gout flares between either group over the entire 12-month study period.

The study findings make a case for continuing colchicine prophylaxis considerably beyond the point at which the target urate serum level is reached, said Robert Terkeltaub, MD, professor emeritus of medicine in the division of rheumatology, allergy, and immunology at the University of California, San Diego. He was not involved with the research.

“The flare burden with this really conservative allopurinol dosing regimen is really stunning,” he said in an interview. Despite this “start low and go slow” strategy, flares remained a problem, he noted. “It argues that you need at least a year to get out of the woods and have a lower flare burden, even if colchicine prophylaxis is used for the first 6 months.”

The current standard of care in rheumatology for gout treatment includes flare prophylaxis when starting urate-lowering therapy. In daily practice, “this can (and often does) mean continuing flare prophylaxis for longer than the recommended minimum duration from [established] gout treatment guidelines for an individual patient,” explained Elizabeth R. Graef, DO, assistant professor of medicine at Boston University and a rheumatologist at Boston Medical Center.

There are many different factors to consider when determining a patient’s flare risk beyond serum urate levels and date of last flare, she noted. Flare severity, concurrent diuretic use, dose changes, tophus count, and additional health conditions such as diabetes can all contribute to individual patient outcomes.

“Gout is an erosive arthritis, and every time someone flares, there’s a risk of permanent erosive damage, so I tend to be more aggressive with prophylaxis,” she said.

The study was funded by the Health Research Council of New Zealand. Dr. Graef disclosed no relevant financial relationships. Dr. Terkeltaub consults for LG Chem, Fortress/Urica, Selecta Biosciences, Horizon Therapeutics, Atom Biosciences, Acquist Therapeutics, Generate Biomedicines, AstraZeneca, and Synlogic. Dr. Terkeltaub serves as the nonsalaried president of the Gout, Hyperuricemia, and Crystal-Associated Disease Network, which annually receives unrestricted arms-length grant support from pharma donors.

The glucose-lowering drug class sodium-glucose cotransporter 2 (SGLT2) inhibitors appear to reduce the risk for recurrent gout flares in people with gout and type 2 diabetes, and to lessen excess mortality in those individuals, compared with those who initiated other types of glucose-lowering medications, new data suggest.

Among nearly 6,000 adults with both type 2 diabetes and gout from a U.K. primary care database, initiation of SGLT2 inhibitor treatment was associated with 19% fewer recurrent gout flares and 29% lower mortality.

Moreover, unlike other urate-lowering therapies, there were no apparent transient increases in the risk of gout flares after initiating therapy, Jie Wei, PhD, of Health Management Center, Xiangya Hospital, Central South University, Changsha, China, and colleagues reported in JAMA Network Open.

These results are important because current management of gout is suboptimal. Many patients either don’t receive adequate urate-lowering therapies such as allopurinol or stop taking them, Dr. Wei and colleagues said.

In addition to lowering glucose, SGLT2 inhibitors also reduce the risk for major adverse cardiovascular events and all-cause mortality in people regardless of their diabetes status. Previous studies have also found that SGLT2 inhibitors reduce the risk for developing gout and of gout flares.

Asked to comment, gout specialist John D. FitzGerald, MD, PhD, clinical chief of rheumatology at the University of California, Los Angeles, said in an interview: “I think it’s a well-done paper, with a large dataset. I think it just reinforces the findings from the other papers. Mostly anything that lowers uric acid levels is going to lower recurrent gout attacks, so it all makes sense.”

However, while Dr. FitzGerald thinks the drug class is a good option for people with diabetes or cardiorenal indications for them who also have gout, he doesn’t envision it as first-line for most other patients with gout. “The current treatments are very effective. Allopurinol brings down uric acid levels by 5-7 points. There are patients who fail allopurinol, but those are less than 5%.”

The most common reason patients stop taking allopurinol is the frequent initial gout flare. But that’s preventable, Dr. FitzGerald said, either by titrating up slowly, or by adding colchicine along with it. “By going slowly, you can avoid that flare risk. I think that’s what’s going on with the SGLT2 inhibitor. It’s not a dramatic urate-lowering drug, but it is clinically meaningful. I think that’s what this paper is showing.”

But, he noted, “I think there are so many reasons to start the SGLT2 inhibitors that if somebody also has gout, all the better. And, if somebody is on the margin with diabetes and gout control and can’t go with allopurinol, it would be great to add for both conditions.”

Less gout recurrence, lower mortality

The retrospective study was conducted from Jan. 1, 2013, to March 31, 2022. Among 5,931 patients with both type 2 diabetes and gout, 1,548 (26.1%) initiated an SGLT2 inhibitor (dapagliflozin, empagliflozin, or canagliflozin), while 4,383 (73.9%) initiated treatment with other active comparators, mostly (92.6%) dipeptidyl peptidase–4 inhibitors.

Gout flares were identified in the charts for a total of 86% of the participants. The weighted incidence rates for the first recurrent flare were 32.4 versus 41.2 per 1,000 person-years in the SGLT2 inhibitor versus comparator groups, with a weighted absolute rate difference of –8.8/1,000 and weighted hazard ratio of 0.81, a significant difference.

All-cause mortality was 18.8 versus 24.9 per 1,000 person-years, respectively, giving an HR of 0.71 at 5-year follow-up.

Dr. FitzGerald, who chaired the American College of Rheumatology’s 2020 gout guidelines, said he anticipates that the SGLT2 inhibitors will be mentioned in the next update to the ACR’s now “living” guidelines, although he was not speaking on the organization’s behalf.

“We talk about losartan in the current [ACR guidelines], about its specific uric acid–lowering effect. Drugs can make uric acid worse or better. For example, thiazides make it higher. I think the SGLT2 [inhibitors] are important, but I don’t think they’re huge. The study is great, and I think the drugs are great, but I don’t think they will change the way gout is managed.”

This work was supported by grants from the National Key Research and Development Plan, the National Natural Science Foundation of China, the Project Program of National Clinical Research Center for Geriatric Disorders, and from the Natural Science Foundation of Hunan Province. Dr. Wei reported receiving grant funding from Xiangya Hospital Central South University Project Program of National Clinical Research Center for Geriatric Disorders and the Science and Technology Department of Hunan Province, the Natural Science Foundation of Hunan Province, during the conduct of the study. Dr. FitzGerald reported no relevant financial relationships.

I think that’s what’s going on with the SGLT2 inhibitor. It’s not a dramatic urate-lowering drug, but it is clinically meaningful. I think that’s what this paper is showing.”

But, he noted, “I think there are so many reasons to start the SGLT2 inhibitors that if somebody also has gout, all the better. And, if somebody is on the margin with diabetes and gout control and can’t go with allopurinol, it would be great to add for both conditions.”

Less gout recurrence, lower mortality

The retrospective study was conducted from Jan. 1, 2013, to March 31, 2022. Among 5,931 patients with both type 2 diabetes and gout, 1,548 (26.1%) initiated an SGLT2 inhibitor (dapagliflozin, empagliflozin, or canagliflozin), while 4,383 (73.9%) initiated treatment with other active comparators, mostly (92.6%) dipeptidyl peptidase–4 inhibitors.

Gout flares were identified in the charts for a total of 86% of the participants. The weighted incidence rates for the first recurrent flare were 32.4 versus 41.2 per 1,000 person-years in the SGLT2 inhibitor versus comparator groups, with a weighted absolute rate difference of –8.8/1,000 and weighted hazard ratio of 0.81, a significant difference.

All-cause mortality was 18.8 versus 24.9 per 1,000 person-years, respectively, giving an HR of 0.71 at 5-year follow-up.

Dr. FitzGerald, who chaired the American College of Rheumatology’s 2020 gout guidelines, said he anticipates that the SGLT2 inhibitors will be mentioned in the next update to the ACR’s now “living” guidelines, although he was not speaking on the organization’s behalf.

“We talk about losartan in the current [ACR guidelines], about its specific uric acid–lowering effect. Drugs can make uric acid worse or better. For example, thiazides make it higher. I think the SGLT2 [inhibitors] are important, but I don’t think they’re huge. The study is great, and I think the drugs are great, but I don’t think they will change the way gout is managed.”

This work was supported by grants from the National Key Research and Development Plan, the National Natural Science Foundation of China, the Project Program of National Clinical Research Center for Geriatric Disorders, and from the Natural Science Foundation of Hunan Province. Dr. Wei reported receiving grant funding from Xiangya Hospital Central South University Project Program of National Clinical Research Center for Geriatric Disorders and the Science and Technology Department of Hunan Province, the Natural Science Foundation of Hunan Province, during the conduct of the study. Dr. FitzGerald reported no relevant financial relationships.

The glucose-lowering drug class sodium-glucose cotransporter 2 (SGLT2) inhibitors appear to reduce the risk for recurrent gout flares in people with gout and type 2 diabetes, and to lessen excess mortality in those individuals, compared with those who initiated other types of glucose-lowering medications, new data suggest.

Among nearly 6,000 adults with both type 2 diabetes and gout from a U.K. primary care database, initiation of SGLT2 inhibitor treatment was associated with 19% fewer recurrent gout flares and 29% lower mortality.

Moreover, unlike other urate-lowering therapies, there were no apparent transient increases in the risk of gout flares after initiating therapy, Jie Wei, PhD, of Health Management Center, Xiangya Hospital, Central South University, Changsha, China, and colleagues reported in JAMA Network Open.

These results are important because current management of gout is suboptimal. Many patients either don’t receive adequate urate-lowering therapies such as allopurinol or stop taking them, Dr. Wei and colleagues said.

In addition to lowering glucose, SGLT2 inhibitors also reduce the risk for major adverse cardiovascular events and all-cause mortality in people regardless of their diabetes status. Previous studies have also found that SGLT2 inhibitors reduce the risk for developing gout and of gout flares.

Asked to comment, gout specialist John D. FitzGerald, MD, PhD, clinical chief of rheumatology at the University of California, Los Angeles, said in an interview: “I think it’s a well-done paper, with a large dataset. I think it just reinforces the findings from the other papers. Mostly anything that lowers uric acid levels is going to lower recurrent gout attacks, so it all makes sense.”

However, while Dr. FitzGerald thinks the drug class is a good option for people with diabetes or cardiorenal indications for them who also have gout, he doesn’t envision it as first-line for most other patients with gout. “The current treatments are very effective. Allopurinol brings down uric acid levels by 5-7 points. There are patients who fail allopurinol, but those are less than 5%.”

The most common reason patients stop taking allopurinol is the frequent initial gout flare. But that’s preventable, Dr. FitzGerald said, either by titrating up slowly, or by adding colchicine along with it. “By going slowly, you can avoid that flare risk. I think that’s what’s going on with the SGLT2 inhibitor. It’s not a dramatic urate-lowering drug, but it is clinically meaningful. I think that’s what this paper is showing.”

The U.S. Food and Drug Administration has approved canakinumab (Ilaris) for the treatment of gout flares in adults who cannot be treated with NSAIDs, colchicine, or repeated courses of corticosteroids. The drug is also indicated for people who could not tolerate or had an inadequate response to NSAIDs or colchicine.

The drug, a humanized anti–interleukin-1 beta monoclonal antibody, is the first and only biologic approved in the United States for the treatment of gout flares, according to Novartis. It is administered in a single, subcutaneous injection of 150 mg.

“At Novartis, we are committed to bringing medicines that address high unmet needs to patients. We are proud to receive approval on our eighth indication for Ilaris in the U.S. and provide the first biologic medicine option for people with gout flares to help treat this painful and debilitating condition,” the company said in a statement to this news organization.

Canakinumab was first approved in the United States in 2009 for the treatment of children and adults with cryopyrin-associated periodic syndrome (CAPS). Since then, it has been approved for the treatment of several other autoinflammatory diseases, including Still’s disease and recurrent fever syndromes.

In 2011, an FDA advisory panel voted against the approval of canakinumab to treat acute gout flares refractory to NSAIDs, colchicine, or repeated courses of corticosteroids, while in 2013, the European Medicine Agency approved the drug for this treatment indication.

Since that FDA advisory committee meeting and the FDA’s subsequent rejection letter, “[Novartis] has conducted additional studies in patients with gout flares and other related populations to further characterize the short- and long-term safety of canakinumab supporting the current application. To further support the benefit-risk [profile of the drug], the indication is for a more restricted population than initially proposed in 2011,” the FDA’s Center for Drug Evaluation and Research said in a statement to this news organization. “Given these considerations and the available safety information, the Agency determined that canakinumab, at the recommended dosage, has a favorable risk-benefit profile” in the specified patient population.

The prevalence of gout is skyrocketing worldwide, and while drugs in the pipeline hold promise for improving the efficacy and safety of treatment, experts warn that “gout remains suboptimally managed.”

“For a really well-understood disease, gout is remarkably undertreated,” said Robert A. Terkeltaub, MD, professor of medicine emeritus at the University of California, San Diego. “This is amazing and depressing because allopurinol has been around for about 60 years or so.”

Randomized, controlled trials show that 80%-90% of patients with gout can be effectively treated to target with existing gout therapies. “Over a year or two, gout flares improve and patients do well,” Dr. Terkeltaub said.

By lowering excessive levels of serum urate, current therapies slow the formation of monosodium urate crystals that precipitate within joints and soft tissues, inducing a highly inflammatory local response with superimposed systemic inflammation. These therapies reduce the frequency of excruciatingly painful gout flares.

“Many patients with gout are not taking urate-lowering therapy at all,” Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School, Boston, and head of crystal-induced arthritis diseases at Brigham and Women’s Hospital, also in Boston, said in an interview.

“Unfortunately, a common problem in gout is treatment inertia,” said Tuhina Neogi, MD, PhD, chief of rheumatology at Boston Medical Center.

On a global scale, only one-third of patients with gout are started on urate-lowering therapy, and more than 50% abandon treatment after 1 year. As a result, the effectiveness of urate-lowering therapies in reality is well below 50%, Dr. Terkeltaub said.

“I think gout has been taken less seriously than it should be for quite some time,” he explained in an interview. Gout’s impact on health and well-being is no trivial matter. A recent study showed that a diagnosis of gout was associated with an increased risk of anxiety and depression, and there is new evidence suggesting that gout flares are associated with an increased risk of cardiovascular events, including fatal myocardial infarction and stroke.

“We need drugs that are not just effective but also safe, and we need to incorporate real-world data into our assessment of treatment effectiveness, especially in the presence of comorbidities,” Dr. Terkeltaub said.

The prevalence of what used to be thought of as the “disease of kings” has increased 100% over the last 30 years, outstripping world population growth and life expectancy. In the United States, an estimated 5% of adults, or 12 million, have gout. Globally, the number affected exceeds 50 million.

The patient demographics associated with gout have also expanded. Once seen primarily in fleshy, middle-aged men of privilege, gout affects more women, more adults at either end of the age spectrum, and more people in Third World countries than ever before.
 

Management

In the United States, the optimal management of gout remains the subject of debate, with differences in expert opinion reflected in evidence-based clinical guidelines. “We know that the perception of gout is different between primary care physicians, patients, and rheumatologists,” Dr. Terkeltaub said.

The 2017 American College of Physicians guidelines for the management of gout recommend a treat-to-symptom approach to urate-lowering therapy. However, the 2020 American College of Rheumatology guidelines reinforce a standard treat-to-target strategy to a serum urate target of < 6.0 mg/dL.

In their report, the ACR guidelines’ authors stated that the use of urate-lowering therapy for gout has not increased in the last decade. Research shows that adherence to treatment for gout continues to be the lowest among seven common chronic medical conditions, including hypertension and seizure disorders, they said.

Some physicians don’t recommend urate-lowering medication to their patients with gout, and others don’t up-titrate it sufficiently to meet the recommended serum urate target, said Dr. Tedeschi. The latter “can require increasing the dose of allopurinol well beyond the 300 mg that often seems the landing point for many patients with gout,” she pointed out.

In fact, it can take up to 800 mg a day of allopurinol – less in patients with moderate to severe kidney disease – to reduce the symptom burden in gout. And it can take a year or longer of drug testing and titration to reach the optimal serum urate target. Paradoxically, gout flares usually get worse during this time.

“We need to reduce the time it takes to get the patient to the serum urate target, and simplify regimens with once-a-day dosing,” Dr. Terkeltaub said. “We also need greater precision so that we can get a home run, hitting the serum urate target the first or second visit, with minimal dose titration.”

Clinician education is important, but education alone is not enough, Dr. Neogi emphasized. “Just as clinicians treat-to-target in other conditions such as hypertension and diabetes, or titrate warfarin to maintain a certain level of anticoagulation, gout must be monitored and treatments adjusted accordingly,” she said.

Practice changes, such as partnering with nursing or pharmacy, may help facilitate in-clinic dose titration, “much like a warfarin clinic,” Dr. Neogi suggested.

That’s exactly what Dr. Terkeltaub has done. Overwhelmed by the number of gout consults, Dr. Terkeltaub and his team set up a pharmacist-managed, rheumatology-supervised clinic to care for gout patients remotely. The model has been very successful, he said. Nurses and clinical pharmacists educate the patients and manage their lab testing and prescriptions, all according to ACR guidelines.

The treatment of gout has become more complex, with a greater risk of drug complications and interactions, particularly in older patients with comorbid diabetes, chronic kidney disease, and heart disease. Many of the patients he sees are already on “10, 15, or 20 other medications,” Dr. Terkeltaub noted.

The steps involved in the titration of urate-lowering therapy also complicate the treatment of gout, making it impractical for many patients and impossible for others whose access to primary care is limited to one or two visits a year. The process of drug titration, with steadily increasing doses, can make patients anxious about the possibility of being overmedicated. Taking a drug every day, even when joints feel “normal,” can also increase the risk of nonadherence.

“In our conversations with patients with gout, it’s extremely important that we counsel them about the need to take urate-lowering therapy on an ongoing basis to reduce the risk of a gout flare,” said Dr. Tedeschi. “Patients need to have prescription refills available and know to contact the doctor before they run out, so that the chances of having a gout flare are reduced.”
 

Current drugs

Although urate-lowering drugs form the cornerstone of gout therapy, there are only three oral medications available in the United States currently, and all have significant limitations. “We need more drugs, basically,” Dr. Terkeltaub said.

• Allopurinol (Zyloprim, Aloprim), an inexpensive xanthine oxidase inhibitor (XOI), is still considered a first-line treatment, but is associated with allopurinol hypersensitivity syndrome. In select patients of Asian, African, and Arab descent, this adverse drug reaction can be life-threatening, and is associated with a mortality rate of 20%-25%.
• Febuxostat (Uloric), another XOI, is considered a second-line drug in the treatment of gout, but has carried a boxed warning from the Food and Drug Administration since 2019. It is associated with a significantly increased risk of cardiovascular death.
• Probenecid (Probalan), a uricosuric agent that increases renal uric acid excretion, is associated with an increased risk of drug interactions and kidney stones, and is rarely used.

Drugs in the pipeline

New drugs in the pipeline offer treatment options that are not only effective but also safe. “This will be important in clinical practice, especially for patients in whom existing medications are contraindicated or there is an increased risk of side effects,” Dr. Neogi said.

Most of these investigational drugs are uricosuric agents that increase the renal excretion of uric acid, reducing serum levels. “The pipeline of new drugs is rich,” Dr. Terkeltaub said. “These drugs are very selective and really work well and they appear to be safe.”

AR882, an inhibitor of selective uric acid transporter 1 (URAT1), is shaping up to be one of them. In July, results from a phase 2b study of AR882 were presented at the annual European Congress of Rheumatology in Milan. They showed that in the intent-to-treat population, 73% of patients had serum uric acid levels < 5 mg/dL and 55% had < 4 mg/dL by week 12 of therapy. In the per-protocol analysis, 82% had serum uric acid levels < 5 mg/dL and 63% < 4 mg/dL.

“These efficacy results are not typically what you see with a once-daily oral medication, so it is really exciting,” said Robert Keenan, MD, chief medical officer of Arthrosi Therapeutics, San Diego, who presented the results.

“More efficacious URAT1 inhibitors that are safe and have a reduced pill burden will be useful additions to current urate lowering options,” Dr. Neogi said.

The recent phase 3 DISSOLVE I and II trials of the investigational uricase-based infusion therapy SEL-212 in refractory gout have also demonstrated encouraging results, particularly in older patients. In DISSOLVE I, a response rate of 65% was observed in patients 50 years of age and older at least 80% of the time during month 6 of treatment. In DISSOLVE II, a response rate of 47% was reported in older patients.

SEL-212, which is made up of PEGylated uricase (pegadricase) coadministered with sirolimus (Rapamycin), will be submitted for U.S. regulatory approval in the first half of 2024.

In the management of gout flares, interleukin (IL)-1beta and inflammasome inhibitors, both of which target specific inflammatory pathways, could also provide attractive additions to urate-lowering therapies. Other agents commonly used in the treatment of flares, such as NSAIDs, steroids, and colchicine (Colcrys), are not as specific, and have side effects that often limit their usability, Dr. Neogi said.

In the meantime, new research indicates that an inflammasome inhibitor that has already been approved for use in diabetes may provide distinct benefits for the management of gout. An analysis of data from 15,067 adults with both gout and type 2 diabetes showed that when a sodium-glucose cotransporter 2 (SGLT-2) inhibitor was added to urate-lowering therapy, the symptoms of gout, including flares, were significantly reduced, resulting in fewer emergency department visits and hospitalizations.

“SGLT-2 inhibitors have anti-inflammatory activity that limits the progression of kidney failure, heart failure, and will also lower the serum uric acid,” said Dr. Terkeltaub. “That’s a major development.”

Dr. Neogi disclosed relationships with Novartis, Pfizer/Lilly, and Regeneron, Dr. Terkeltaub reported relationships with Dyve, Fortress, and Atom, and Dr. Tedeschi reported a relationship with Novartis.

“More efficacious URAT1 inhibitors that are safe and have a reduced pill burden will be useful additions to current urate lowering options,” Dr. Neogi said.

The recent phase 3 DISSOLVE I and II trials of the investigational uricase-based infusion therapy SEL-212 in refractory gout have also demonstrated encouraging results, particularly in older patients. In DISSOLVE I, a response rate of 65% was observed in patients 50 years of age and older at least 80% of the time during month 6 of treatment. In DISSOLVE II, a response rate of 47% was reported in older patients.

SEL-212, which is made up of PEGylated uricase (pegadricase) coadministered with sirolimus (Rapamycin), will be submitted for U.S. regulatory approval in the first half of 2024.

In the management of gout flares, interleukin (IL)-1beta and inflammasome inhibitors, both of which target specific inflammatory pathways, could also provide attractive additions to urate-lowering therapies. Other agents commonly used in the treatment of flares, such as NSAIDs, steroids, and colchicine (Colcrys), are not as specific, and have side effects that often limit their usability, Dr. Neogi said.

In the meantime, new research indicates that an inflammasome inhibitor that has already been approved for use in diabetes may provide distinct benefits for the management of gout. An analysis of data from 15,067 adults with both gout and type 2 diabetes showed that when a sodium-glucose cotransporter 2 (SGLT-2) inhibitor was added to urate-lowering therapy, the symptoms of gout, including flares, were significantly reduced, resulting in fewer emergency department visits and hospitalizations.

“SGLT-2 inhibitors have anti-inflammatory activity that limits the progression of kidney failure, heart failure, and will also lower the serum uric acid,” said Dr. Terkeltaub. “That’s a major development.”

Dr. Neogi disclosed relationships with Novartis, Pfizer/Lilly, and Regeneron, Dr. Terkeltaub reported relationships with Dyve, Fortress, and Atom, and Dr. Tedeschi reported a relationship with Novartis.

The prevalence of gout is skyrocketing worldwide, and while drugs in the pipeline hold promise for improving the efficacy and safety of treatment, experts warn that “gout remains suboptimally managed.”

“For a really well-understood disease, gout is remarkably undertreated,” said Robert A. Terkeltaub, MD, professor of medicine emeritus at the University of California, San Diego. “This is amazing and depressing because allopurinol has been around for about 60 years or so.”

Randomized, controlled trials show that 80%-90% of patients with gout can be effectively treated to target with existing gout therapies. “Over a year or two, gout flares improve and patients do well,” Dr. Terkeltaub said.

By lowering excessive levels of serum urate, current therapies slow the formation of monosodium urate crystals that precipitate within joints and soft tissues, inducing a highly inflammatory local response with superimposed systemic inflammation. These therapies reduce the frequency of excruciatingly painful gout flares.

“Many patients with gout are not taking urate-lowering therapy at all,” Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School, Boston, and head of crystal-induced arthritis diseases at Brigham and Women’s Hospital, also in Boston, said in an interview.

“Unfortunately, a common problem in gout is treatment inertia,” said Tuhina Neogi, MD, PhD, chief of rheumatology at Boston Medical Center.

On a global scale, only one-third of patients with gout are started on urate-lowering therapy, and more than 50% abandon treatment after 1 year. As a result, the effectiveness of urate-lowering therapies in reality is well below 50%, Dr. Terkeltaub said.

“I think gout has been taken less seriously than it should be for quite some time,” he explained in an interview. Gout’s impact on health and well-being is no trivial matter. A recent study showed that a diagnosis of gout was associated with an increased risk of anxiety and depression, and there is new evidence suggesting that gout flares are associated with an increased risk of cardiovascular events, including fatal myocardial infarction and stroke.

“We need drugs that are not just effective but also safe, and we need to incorporate real-world data into our assessment of treatment effectiveness, especially in the presence of comorbidities,” Dr. Terkeltaub said.

The prevalence of what used to be thought of as the “disease of kings” has increased 100% over the last 30 years, outstripping world population growth and life expectancy. In the United States, an estimated 5% of adults, or 12 million, have gout. Globally, the number affected exceeds 50 million.

The patient demographics associated with gout have also expanded. Once seen primarily in fleshy, middle-aged men of privilege, gout affects more women, more adults at either end of the age spectrum, and more people in Third World countries than ever before.
 

Management

In the United States, the optimal management of gout remains the subject of debate, with differences in expert opinion reflected in evidence-based clinical guidelines. “We know that the perception of gout is different between primary care physicians, patients, and rheumatologists,” Dr. Terkeltaub said.

The 2017 American College of Physicians guidelines for the management of gout recommend a treat-to-symptom approach to urate-lowering therapy. However, the 2020 American College of Rheumatology guidelines reinforce a standard treat-to-target strategy to a serum urate target of < 6.0 mg/dL.

In their report, the ACR guidelines’ authors stated that the use of urate-lowering therapy for gout has not increased in the last decade. Research shows that adherence to treatment for gout continues to be the lowest among seven common chronic medical conditions, including hypertension and seizure disorders, they said.

Some physicians don’t recommend urate-lowering medication to their patients with gout, and others don’t up-titrate it sufficiently to meet the recommended serum urate target, said Dr. Tedeschi. The latter “can require increasing the dose of allopurinol well beyond the 300 mg that often seems the landing point for many patients with gout,” she pointed out.

In fact, it can take up to 800 mg a day of allopurinol – less in patients with moderate to severe kidney disease – to reduce the symptom burden in gout. And it can take a year or longer of drug testing and titration to reach the optimal serum urate target. Paradoxically, gout flares usually get worse during this time.

“We need to reduce the time it takes to get the patient to the serum urate target, and simplify regimens with once-a-day dosing,” Dr. Terkeltaub said. “We also need greater precision so that we can get a home run, hitting the serum urate target the first or second visit, with minimal dose titration.”

Clinician education is important, but education alone is not enough, Dr. Neogi emphasized. “Just as clinicians treat-to-target in other conditions such as hypertension and diabetes, or titrate warfarin to maintain a certain level of anticoagulation, gout must be monitored and treatments adjusted accordingly,” she said.

Practice changes, such as partnering with nursing or pharmacy, may help facilitate in-clinic dose titration, “much like a warfarin clinic,” Dr. Neogi suggested.

That’s exactly what Dr. Terkeltaub has done. Overwhelmed by the number of gout consults, Dr. Terkeltaub and his team set up a pharmacist-managed, rheumatology-supervised clinic to care for gout patients remotely. The model has been very successful, he said. Nurses and clinical pharmacists educate the patients and manage their lab testing and prescriptions, all according to ACR guidelines.

The treatment of gout has become more complex, with a greater risk of drug complications and interactions, particularly in older patients with comorbid diabetes, chronic kidney disease, and heart disease. Many of the patients he sees are already on “10, 15, or 20 other medications,” Dr. Terkeltaub noted.

The steps involved in the titration of urate-lowering therapy also complicate the treatment of gout, making it impractical for many patients and impossible for others whose access to primary care is limited to one or two visits a year. The process of drug titration, with steadily increasing doses, can make patients anxious about the possibility of being overmedicated. Taking a drug every day, even when joints feel “normal,” can also increase the risk of nonadherence.

“In our conversations with patients with gout, it’s extremely important that we counsel them about the need to take urate-lowering therapy on an ongoing basis to reduce the risk of a gout flare,” said Dr. Tedeschi. “Patients need to have prescription refills available and know to contact the doctor before they run out, so that the chances of having a gout flare are reduced.”
 

Current drugs

Although urate-lowering drugs form the cornerstone of gout therapy, there are only three oral medications available in the United States currently, and all have significant limitations. “We need more drugs, basically,” Dr. Terkeltaub said.

• Allopurinol (Zyloprim, Aloprim), an inexpensive xanthine oxidase inhibitor (XOI), is still considered a first-line treatment, but is associated with allopurinol hypersensitivity syndrome. In select patients of Asian, African, and Arab descent, this adverse drug reaction can be life-threatening, and is associated with a mortality rate of 20%-25%.
• Febuxostat (Uloric), another XOI, is considered a second-line drug in the treatment of gout, but has carried a boxed warning from the Food and Drug Administration since 2019. It is associated with a significantly increased risk of cardiovascular death.
• Probenecid (Probalan), a uricosuric agent that increases renal uric acid excretion, is associated with an increased risk of drug interactions and kidney stones, and is rarely used.

Drugs in the pipeline

New drugs in the pipeline offer treatment options that are not only effective but also safe. “This will be important in clinical practice, especially for patients in whom existing medications are contraindicated or there is an increased risk of side effects,” Dr. Neogi said.

Most of these investigational drugs are uricosuric agents that increase the renal excretion of uric acid, reducing serum levels. “The pipeline of new drugs is rich,” Dr. Terkeltaub said. “These drugs are very selective and really work well and they appear to be safe.”

AR882, an inhibitor of selective uric acid transporter 1 (URAT1), is shaping up to be one of them. In July, results from a phase 2b study of AR882 were presented at the annual European Congress of Rheumatology in Milan. They showed that in the intent-to-treat population, 73% of patients had serum uric acid levels < 5 mg/dL and 55% had < 4 mg/dL by week 12 of therapy. In the per-protocol analysis, 82% had serum uric acid levels < 5 mg/dL and 63% < 4 mg/dL.

“These efficacy results are not typically what you see with a once-daily oral medication, so it is really exciting,” said Robert Keenan, MD, chief medical officer of Arthrosi Therapeutics, San Diego, who presented the results.

“More efficacious URAT1 inhibitors that are safe and have a reduced pill burden will be useful additions to current urate lowering options,” Dr. Neogi said.

In DISSOLVE II, a response rate of 47% was reported in older patients.

TOPLINE:

Treatment of adults with type 2 diabetes and gout with a sodium-glucose cotransporter 2 (SGLT2) inhibitor was significantly linked with fewer gout flares, compared with matched patients treated with a dipeptidyl peptidase–4 (DPP-4) inhibitor.

METHODOLOGY:

• The study used observational data collected from the entire population of British Columbia that included 15,067 adults with both gout and type 2 diabetes in 2014-2020.
• The group included 8,318 patients who initiated an SGLT2 inhibitor and 6,749 patients who initiated a DPP-4 inhibitor during the study period after at least 1 year of continuous enrollment.
• Using propensity-score matching, 4,075 matched pairs were identified, where one person initiated an SGLT2 inhibitor and the other started a DPP-4 inhibitor.
• Primary outcome was recurrent gout flare counts during follow-up that required an ED visit, hospital admission, or an outpatient visit for a gout flare coupled with appropriate treatment, tallied from the first day of drug receipt until June 30, 2022, with an average follow-up of 1.6 years.
• Secondary endpoints included the incidence of myocardial infarction and stroke.

TAKEAWAY:

• Total gout-flare rates after SGLT2 inhibitor initiation were 52.4/1000 person-years and after DPP-4 inhibitor initiation were 79.7/1,000 person-years, an adjusted rate ratio of 0.66, a reduction significantly linked with SGLT2 inhibitor use.
• For flares that required an ED visit or hospitalization, initiation of an SGLT2 inhibitor was linked with a significant, reduced aRR of 0.52, compared with DPP-4 inhibitor initiation.
• The flare-rate reduction linked with SGLT2 inhibitor use was consistent regardless of sex, age, baseline diuretic use, prior treatment with a urate-lowering agent, and baseline gout intensity.
• SGLT2 inhibitor initiation was also significantly linked with an adjusted reduced hazard ratio of 0.69 in the incidence of myocardial infarction, compared with DPP-4 inhibitor initiation, but stroke incidence was not significantly different between the groups.

IN PRACTICE:

These findings suggest that SGLT2 inhibitors could have a much-needed ability to simultaneously reduce the burden of recurrent gout flares and coronary sequelae in patients with gout and type 2 diabetes, indicating that “SGLT2 inhibitors may offer distinct benefits,” making the drug class “a particularly attractive addition to current urate-lowering therapies,” the researchers write.

SOURCE:

The study was primarily conducted by researchers at Massachusetts General Hospital in Boston. The study was published online July 24 in Annals of Internal Medicine.

LIMITATIONS:

The data used in the study did not include gout flares that did not require medical attention and did not include laboratory findings for study participants. Because the data were observational the findings may be susceptible to unmeasured confounding.

DISCLOSURES:

The study received no commercial funding. One author has reported receiving consulting fees from ANI and LG Chem.

The recent Food and Drug Administration approval of colchicine 0.5 mg (Lodoco) for use in atherosclerotic cardiovascular disease (ASCVD) prevention will possibly create opportunities to use the drug to treat residual risk for ASCVD in some patients with immune-mediated inflammatory diseases, particularly in rheumatology.

Potential in rheumatology

The 0.5-mg dose is just a shade under the 0.6-mg, twice daily dosing rheumatologists typically prescribe for gout, Christie Bartels, MD, MS, chief of rheumatology at the University of Wisconsin–Madison, said in an interview. Clinicians also use the 0.6-mg dose off-label for pseudogout or calcium pyrophosphate deposition disease (CPPD), Dr. Bartels noted.

University of Wisconsin

The new formulation opens the consideration for using colchicine more in patients with psoriatic arthritis, lupus, and rheumatoid arthritis, she said. “I think we could certainly discuss it, particularly, in secondary prevention patients who already had an event or who are at the highest risk and already on optimal traditional agents,” she said.

She cited previous comments by Paul Ridker, MD, director of the center for cardiovascular disease prevention at Brigham and Women’s Hospital in Boston, and developer of the high-sensitivity C-reactive protein (hsCRP) test for measuring inflammatory markers. “We might not know the answer because Dr. Ridker pointed out he used colchicine 0.5 mg in patients that had a high-sensitivity CRP that was high; we need patients who have had inflammation of unknown origin, so those patients presumably weren’t already on another anti-inflammatory,” she said, noting that hydroxychloroquine, methotrexate, and some biologics provide some protection from cardiovascular risks.

However, a potential role for long-term colchicine 0.5 mg in ASCVD prevention may cause consideration for changing the drug’s role in gout treatment, Dr. Bartels said. “In gout, where we do have an FDA-approved indication for colchicine, we used to use it only for the first 6 months while we were getting patients to goal on allopurinol, which was usually then monotherapy after the first 6 months,” she said. “I think this will likely change how I treat gout patients in that I may also offer to continue both medications [colchicine and allopurinol] if they are tolerating them well.

“And then in patients where I’m using it off-label in CPPD, I might again share with them that in addition to possibly helping their CPPD, there may be this added benefit to reduce inflammation just in discussing the risks and benefits of the medicine.”

However, rheumatologists must be careful in using colchicine beyond the typical 6-month cycle, Dr. Bartels said. “One of the tricky things with colchicine, and part of the reason we did not traditionally continue it specifically past the first 6 months, was that it can cause myopathies or cytopenias, so we still have to counsel patients regarding these risks and monitor that,” she said.

Additionally, colchicine can have drug interactions with statins or calcium channel blockers that can change colchicine levels. “I think the dose here is so low, the 0.5 mg, that it’s probably still safe, but again, it’s something that we have to take a look at in the patient’s whole picture and the rest of their burden of their meds in order to make a decision with them,” Dr. Bartels said.

Possibilities in dermatology

The LoDoCo2 trial one of two major randomized trials that supported approval of colchicine 0.5 mg, reported that treated patients had a 60% lower rate of gout than the placebo group (1.4% vs. 3.4%). Joel Gelfand, MD, MSCE, the James J. Leyden professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, pointed to this in evaluating the dermatologic implications of the drug’s approval. “This may be of particular interest as people with psoriasis have an increased risk of gout,” he said in emailed comments.

University of Pennsylvania

Colchicine’s mechanism of action to reduce inflammation parallels that of tumor necrosis factor (TNF) inhibitors used for dermatologic indications, namely by inhibiting leukocyte adhesion to disrupt the downregulation of TNF receptors, Dr. Gelfand said.

“Interestingly, observational data suggests biologics that target TNF such as adalimumab, etanercept, etc., are associated with a reduction in CV events, and in placebo-controlled trials we conducted in psoriasis patients, it reduced key inflammatory mediators of cardiovascular disease, including IL [interleukin]-6,” he said. “Randomized clinical trials to evaluate the ability of TNF inhibitors, which are now available as biosimilars, to prevent cardiovascular events in high-risk patients, should be conducted, and more work is needed to identify which additional immune-targeted treatments may lower CV risk with an acceptable safety profile.”

Colchicine currently has few indications for rare conditions in dermatology, Dr. Gelfand said, including Sweets syndrome, subcorneal pustular dermatosis, and cutaneous vasculitis. “There are some reports to suggest it may help psoriatic disease, but current data are limited and insufficient to recommend its use for psoriasis and/or psoriatic arthritis,” he said.

The approval of colchicine 0.5 mg for ASCVD could be meaningful for people with psoriasis who are also being treated for CV risk factors, Dr. Gelfand said. “Additional considerations such as signs of residual inflammation (elevated hsCRP) and CV imaging findings may be used to further guide shared decision-making for optimal use,” he said.

Another consideration he noted: “This is also a novel 0.5-mg formulation, and thus cost may be an issue.”
 

Would side effects bar use in gastroenterology?

Colchicine 0.5 mg may not move the needle much for expanding treatment of ASCVD in patients with inflammatory bowel disease (IBD) and potentially other gastrointestinal conditions, Edward Loftus Jr., MD, the Maxine and Jack Zarrow Family professor of gastroenterology specifically for IBD at the Mayo Clinic in Rochester, Minn., told MDEdge in emailed comments. “Given the GI side effect profile [of colchicine], I am not sure I would go there,” he said.

Mayo Clinic

“Hopefully, the prescribers of this low-dose formulation are aware of the gastrointestinal side effects, such as diarrhea and nausea, and educate patients about these side effects so that a proper risk-benefit discussion can ensue,” he said.

Dr. Bartels reporting a previous financial relationship with Pfizer. Dr. Gelfand said he has financial relationships with AbbVie, Amgen, Bristol-Myers Squibb, Boehringer Ingelheim, Celldex, GlaxoSmithKline, Twill, Lilly, Leo, Moonlake, Janssen Biologics, Novartis, Pfizer, UCB, Neuroderm, and Veolia North America. Dr. Loftus disclosed relationships with AbbVie, Alvotech, Amgen, Arena, Avalo, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene/Receptos, Celltrion Healthcare, Eli Lilly, Fresenius Kabi, Genentech, Gilead, GlaxoSmithKline, Gossamer Bio, Iterative Health, Janssen, KSL Diagnostics, Morphic, Ono, Pfizer, Sun, Surrozen, Takeda, Theravance, and UCB.

The approval of colchicine 0.5 mg for ASCVD could be meaningful for people with psoriasis who are also being treated for CV risk factors, Dr. Gelfand said. “Additional considerations such as signs of residual inflammation (elevated hsCRP) and CV imaging findings may be used to further guide shared decision-making for optimal use,” he said.

Another consideration he noted: “This is also a novel 0.5-mg formulation, and thus cost may be an issue.”
 

Would side effects bar use in gastroenterology?

Colchicine 0.5 mg may not move the needle much for expanding treatment of ASCVD in patients with inflammatory bowel disease (IBD) and potentially other gastrointestinal conditions, Edward Loftus Jr., MD, the Maxine and Jack Zarrow Family professor of gastroenterology specifically for IBD at the Mayo Clinic in Rochester, Minn., told MDEdge in emailed comments. “Given the GI side effect profile [of colchicine], I am not sure I would go there,” he said.

“Hopefully, the prescribers of this low-dose formulation are aware of the gastrointestinal side effects, such as diarrhea and nausea, and educate patients about these side effects so that a proper risk-benefit discussion can ensue,” he said.

The recent Food and Drug Administration approval of colchicine 0.5 mg (Lodoco) for use in atherosclerotic cardiovascular disease (ASCVD) prevention will possibly create opportunities to use the drug to treat residual risk for ASCVD in some patients with immune-mediated inflammatory diseases, particularly in rheumatology.

Potential in rheumatology

The 0.5-mg dose is just a shade under the 0.6-mg, twice daily dosing rheumatologists typically prescribe for gout, Christie Bartels, MD, MS, chief of rheumatology at the University of Wisconsin–Madison, said in an interview. Clinicians also use the 0.6-mg dose off-label for pseudogout or calcium pyrophosphate deposition disease (CPPD), Dr. Bartels noted.

The new formulation opens the consideration for using colchicine more in patients with psoriatic arthritis, lupus, and rheumatoid arthritis, she said. “I think we could certainly discuss it, particularly, in secondary prevention patients who already had an event or who are at the highest risk and already on optimal traditional agents,” she said.

She cited previous comments by Paul Ridker, MD, director of the center for cardiovascular disease prevention at Brigham and Women’s Hospital in Boston, and developer of the high-sensitivity C-reactive protein (hsCRP) test for measuring inflammatory markers. “We might not know the answer because Dr. Ridker pointed out he used colchicine 0.5 mg in patients that had a high-sensitivity CRP that was high; we need patients who have had inflammation of unknown origin, so those patients presumably weren’t already on another anti-inflammatory,” she said, noting that hydroxychloroquine, methotrexate, and some biologics provide some protection from cardiovascular risks.

However, a potential role for long-term colchicine 0.5 mg in ASCVD prevention may cause consideration for changing the drug’s role in gout treatment, Dr. Bartels said. “In gout, where we do have an FDA-approved indication for colchicine, we used to use it only for the first 6 months while we were getting patients to goal on allopurinol, which was usually then monotherapy after the first 6 months,” she said. “I think this will likely change how I treat gout patients in that I may also offer to continue both medications [colchicine and allopurinol] if they are tolerating them well.

“And then in patients where I’m using it off-label in CPPD, I might again share with them that in addition to possibly helping their CPPD, there may be this added benefit to reduce inflammation just in discussing the risks and benefits of the medicine.”

However, rheumatologists must be careful in using colchicine beyond the typical 6-month cycle, Dr. Bartels said. “One of the tricky things with colchicine, and part of the reason we did not traditionally continue it specifically past the first 6 months, was that it can cause myopathies or cytopenias, so we still have to counsel patients regarding these risks and monitor that,” she said.

Additionally, colchicine can have drug interactions with statins or calcium channel blockers that can change colchicine levels. “I think the dose here is so low, the 0.5 mg, that it’s probably still safe, but again, it’s something that we have to take a look at in the patient’s whole picture and the rest of their burden of their meds in order to make a decision with them,” Dr. Bartels said.

Possibilities in dermatology

The LoDoCo2 trial one of two major randomized trials that supported approval of colchicine 0.5 mg, reported that treated patients had a 60% lower rate of gout than the placebo group (1.4% vs. 3.4%). Joel Gelfand, MD, MSCE, the James J. Leyden professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, pointed to this in evaluating the dermatologic implications of the drug’s approval. “This may be of particular interest as people with psoriasis have an increased risk of gout,” he said in emailed comments.

Colchicine’s mechanism of action to reduce inflammation parallels that of tumor necrosis factor (TNF) inhibitors used for dermatologic indications, namely by inhibiting leukocyte adhesion to disrupt the downregulation of TNF receptors, Dr. Gelfand said.

“Interestingly, observational data suggests biologics that target TNF such as adalimumab, etanercept, etc., are associated with a reduction in CV events, and in placebo-controlled trials we conducted in psoriasis patients, it reduced key inflammatory mediators of cardiovascular disease, including IL [interleukin]-6,” he said. “Randomized clinical trials to evaluate the ability of TNF inhibitors, which are now available as biosimilars, to prevent cardiovascular events in high-risk patients, should be conducted, and more work is needed to identify which additional immune-targeted treatments may lower CV risk with an acceptable safety profile.”
