Remission and Low Disease Activity Are Associated with Lower Health Care Costs in an International Inception Cohort of Patients with Systemic Lupus Erythematosus
This international study of lupus found that getting the disease into remission or a low disease activity state translates into lower health care costs.

More Than Half of RA Patients with a Lifetime History of Mood Disorders were Anxious and Depressed During COVID-19 Pandemic
A study of people with RA across Canada (the CATCH cohort) found that people with RA experienced increased rates of depression and anxiety, especially during the early phases of the COVID pandemic and with each subsequent waves, compared to before the pandemic This was more marked in individuals with a prior history of mood disorders; they were twice as likely to report anxiety or depression. Whereas rates of depression peaked early in the pandemic, anxiety increased with each successive COVID-19 wave.

Using Administrative Health Data to Construct a Frailty Index as a Measure of Susceptibility to Adverse Health Outcomes Among Individuals with Rheumatoid Arthritis
We created a new tool, known as a frailty index, to measure the risk of worse health outcomes among individuals living with rheumatoid arthritis (RA). Using administrative health data for the province of British Columbia, we found that frailty index scores measured shortly after RA diagnosis predicted later risk of emergency department visits, hospital admissions, and death.

In a long-term study of ~30,000 men and women, we found that adopting an overall healthy lifestyle was associated with a reduced risk of developing gout, especially among people born with a higher genetic risk for gout. Alongside more established factors like keeping a healthy body weight and reducing alcohol consumption, lifestyle factors like physical activity and smoking may also impact future risk of gout.

PROs and Sociodemographic Factors in Year Prior to COVID Predict Trajectories of Depressive Symptoms in Adults with RA in First 2 Years of Pandemic: Data from the Canadian Early Arthritis Cohort.
Although 60% of Canadian RA patients had consistently good mental health during the first 2 years of the COVID-19 pandemic, more than 1 in 5 reported deteriorating mood suggesting a cumulative impact over time; 9% had persistent depression and 8% improving mood. The proportion of adults with RA with at least mild symptoms of depression may be more than twice that reported for the general Canadian population. As compared with those with good mental health throughout, participants with worsening depressive symptoms during the pandemic were more likely to be female, obese, have higher pre-pandemic disease activity, symptoms, disability, and higher impairments in participation. Given the impact of depression on quality of life, inflammation, and disease management, vulnerable groups may benefit from more frequent evaluation and additional support from rheumatology providers.

Long-term consumption of sugared beverages has been associated with an increased risk of developing gout, and in this study of people who already had gout, we also found that greater consumption of fruit juices and other sugared beverages could lead to flares within the next 1-2 days.

Comparison of the Systemic Lupus International Collaborating Clinics Frailty Index (SLICC-FI) and the FRAIL Scale for Identifying Frailty Among Individuals with Systemic Lupus Erythematosus.
This study compared two instruments that measure frailty in people with lupus for different purposes and found moderate agreement between the two. Each frailty measure has distinct advantages in different settings. The FRAIL scale may be a more useful tool to use in clinical care, while the SLICC-FI is more suited to identifying frailty for research purposes.

Reading the Waves: Identifying Distinct Phenotypes of Multisystem Inflammatory Syndrome in Children During the 2020-2021 COVID-19 Pandemic
Children with COVID-19 are at risk of a severe disease that causes inflammation in multiple systems, called MIS-C which can require ICU admission. This study found that over the course of the COVID-19 pandemic, the clinical presentation changed, likely due distinct SARS-CoV-2 variants.
Contemporary Racial/Ethnic Disparities in Emergency Department Visits and Hospitalizations for Gout in the United States – 2019 Nationwide Analysis
We found that Black adults had much higher rates of emergency room visits and hospitalisations for gout than White adults, and longer hospital stays. These findings could reflect a higher risk of gout among Black adults than White, and potentially lower quality of care.

The Independent Impact of Gout on Mortality and Risk of Coronary Heart Disease Among Women – a Prospective Cohort Analysis of Women over 34 Years
We analysed data from >100,000 women followed over 34 years and found that women with gout had more cardiovascular risk factors (i.e., high blood pressure, high cholesterol) than women without gout and tended to die earlier, particularly from cardiovascular diseases.

Hydroxychloroquine Dosing Less Than 5 Mg/kg/day Leads to Increased Hospitalizations for Systemic Lupus Erythematosus Flares
Recent guidelines have recommended a lower dose of hydroxychloroquine in lupus based on weight (≤5 mg per kg) to reduce the risk of toxicity to the retina of the eye. This study found that people with lupus who were treated with this doses of HCQ (compared to those treated with > 5 mg/kg) had a four times higher risk of hospitalizations for a lupus flare. These results indicate the need to reassess the optimal dosing of hydroxychloroquine for patients with SLE.

Impact of Colchicine Prophylaxis on Cardiovascular Outcome Among Gout Patients: A Secondary Analysis of CARES Trial
This study used data from a clinical trial comparing gout treatments to see if the use of colchicine to prevent flares also prevented cardiovascular events, like heart attacks and strokes. No benefit was found, but colchicine use was only 6 months on average, which may not have been long enough to see a benefit on cardiovascular diseases.

Both men and women report impairments with work and leisure activities that improve over time but plateau. A small proportion of ERA patients stop work due to RA or report retiring early with sex differences between those that stop vs continue driven mostly by age, number of people living in the household, pain and mental health. Women that stop working due to RA are less likely than men to report returning to work. Interventions to optimize continued engagement in work may improve productivity outcomes for RA patients and their employers.

This study looked at the employment trajectory of young adults with lupus. Contrary to what is seen in youth from the general population, rates of employment did not increase with increasing age, and little to no increases in transitions from non-employed states to employment were observed. Difficulties in establishing employment during young adulthood is a major concern for this population.

More Meticulously Following Treat-To-Target in RA Does Not Lead to Less Radiographic Progression: A Longitudinal Analysis in BIODAM
A study of people with Rheumatoid Arthritis followed as part of a registry of patients using biologics agents (BIODAM) did not find any difference in radiographic progression over 6 months when people were treated with a strict application of the Treat-to-Target approach to treatment compared to when a more liberal treat-to-target approach was applied.
