Article Synopsis
  • A study compared fatigue levels in a large group of people with systemic sclerosis (SSc) to typical fatigue levels in the general population, finding that SSc patients experienced significantly more fatigue.
  • Participants included 2,385 individuals, with a majority being female and averaging around 55 years old, and it was noted that 18% reported mild fatigue, 27% moderate fatigue, and 8% severe fatigue.
  • Factors such as age, gender, marital status, fatigue-related lifestyle choices (like smoking and BMI), and specific disease features (like gastrointestinal issues and joint problems) were all linked to higher fatigue scores in SSc patients.

Article Synopsis
  • The study examined changes in work status, financial adequacy, and preferences for remote versus in-office work among individuals with systemic sclerosis during the COVID-19 pandemic.
  • Conducted with 298 participants, findings revealed that most people's work status and financial well-being remained stable from April 2020 to August 2022, with only a few changes in employment.
  • Participants preferred flexible work arrangements, but most were required to work in a fixed, in-person setting, suggesting a need for more adaptable workplace policies to accommodate their conditions.

Article Synopsis
  • - The study aims to categorize systemic lupus erythematosus (SLE) patients into distinct phenotypes based on various clinical and laboratory characteristics, excluding autoantibody profiles.
  • - Researchers analyzed data from 440 SLE patients, mainly women, and identified three subgroups: one with severe manifestations linked to antiphospholipid syndrome, another with mild articular symptoms, and a third with diverse clinical features and high autoantibody positivity.
  • - The findings emphasize the heterogeneity of SLE, suggesting that different patient subgroups may require tailored treatment approaches based on their specific disease manifestations.

Objective: Symptoms of anxiety increased early in the COVID-19 pandemic among people with systemic sclerosis (SSc) then returned to pre-pandemic levels, but this was an aggregate finding and did not evaluate whether vaccination may have contributed to reduced anxiety symptom levels. We investigated whether being vaccinated for COVID-19 was associated with reduced anxiety symptoms among people with SSc.

Methods: The longitudinal Scleroderma Patient-centered Intervention Network (SPIN) COVID-19 Cohort was launched in April 2020 and included participants from the ongoing SPIN Cohort and external enrollees.

Article Synopsis
  • Patients with X linked agammaglobulinemia and those receiving anti-CD20 monoclonal antibodies (mAbs) for immune-mediated inflammatory diseases (IMIDs) are at increased risk for severe enterovirus (EV) infections, particularly meningoencephalitis.
  • A study collected data from nine original cases and 17 previously published cases, revealing a high occurrence of meningoencephalitis (81%) and a mortality rate of 27% among affected patients treated with multiple anti-CD20 mAbs.
  • The findings suggest that clinicians should consider EV infections in IMID patients presenting unusual symptoms and recognize that anti-CD20 mAbs can impair B-cell responses to EV infections, potentially indicating
