Objective: To assess the prevalence of and risk factors for depression in a cohort of patients with polymyalgia rheumatica (PMR) compared with a cohort of participants without PMR (control group).

Methods: In a longitudinal cohort study, patients with recently diagnosed PMR (within 3 months of starting treatment) were recruited together with matched control subjects. Assessments were undertaken 3 and 21 months after initiation of steroid therapy. Mood was assessed using the Hospital Anxiety and Depression Scale (HADS) and the 36-item Short-Form Survey (SF-36) Mental Health (MH) scale, with scores ≥8 on the HADS and ≤56 on the SF-36 MH Scale indicating depression. Other data collected included current prednisolone dose, PMR-Activity Score, pain visual analog scale, SF-36, and Health Assessment Questionnaire Disability Index.

Results: Thirty-six subjects with PMR and 32 control subjects were recruited. At baseline, depression rates were significantly higher in PMR cases than in control subjects (22.2% vs. 3.1% and 25.0% vs. 0.0% as determined by HADS and SF-36 MH Scale, respectively). After adjusting for a previous diagnosis of depression, poor physical function (Health Assessment Questionnaire Disability Index) had the strongest association with depression determined by SF-36 MH Scale, with odds ratios of 8.19 (95% confidence interval, 1.06-63.46; p = 0.04) and 13.25 (95% confidence interval, 1.15-152.31; p = 0.04) at baseline and follow-up, respectively. Other significant associations with depression were identified with current prednisolone dose, disease activity (PMR-Activity Score), pain (pain visual analog scale and SF-36 Bodily Pain Scale), and fatigue (SF-36 Vitality Scale).

Conclusion: Depression affects up to 1 in 4 patients with PMR. The strongest association is with poor physical function, highlighting the psychological impact of physical limitations in PMR and the need to address comorbid depression to optimize patient outcomes.

Background: Patients with autoimmune rheumatic diseases (ARDs) are at an increased risk for herpes zoster (HZ). Vaccination is recommended for this population.

Objective: The aim of this study was to evaluate the safety of vaccination with the recombinant zoster vaccine (Shingrix) in ARD patients, humoral immunogenicity (HI), cellular immunogenicity (CI), and the incidence of HZ.

Methods: This randomized, double-blind, placebo-controlled phase 4 study involves 1180 ARD patients and a control group (CG) of 393 balanced healthy individuals, aged ≥50 years. ARD patients will be randomly assigned in a blinded manner (1:1 ratio) to 2 groups: vaccine or placebo (on days 0 and 42), administered intramuscularly. Outcomes will be assessed at baseline, 6 weeks, and 12 weeks after vaccination, including disease activity (using specific disease activity scores), HI, and CI. Adverse events will be assessed using a standardized questionnaire after each vaccine dose. Incident HZ cases will be monitored throughout the study. One year following the second dose, the persistence of HI and CI will be evaluated in both ARD patients and CG. HI and CI will be assessed using serum concentrations of anti-gE antibodies and the frequencies of gE-specific CD4+ T cells, respectively. Comparisons of anti-gE titers between ARD patients and CG at different time points will be analyzed using 2-way repeated-measures analysis of variance. Multiple regression analysis will be conducted, with a positive immune response as the dependent variable, and variables with p < 0.2 from univariate analysis as independent variables.

Conclusions: This large trial addresses a critical gap by examining disease safety, efficacy, adverse effects, and immunogenicity, considering the impact of diverse therapies following recombinant zoster vaccine administration in ARD patients.

Objectives: The aims of this study were to describe the frequency of pleuropulmonary computed tomography (CT) findings in patients with IgG4-related disease (IgG4-RD) and to compare clinical and laboratory characteristics between patients with and without pleuropulmonary involvement in chest CT.

Methods: This is a study conducted within the IgG4-RD study group of the Argentine Society of Rheumatology (GESAR IgG4) cohort of patients with IgG4-RD. Member centers of the group were requested to submit pulmonary CT scans of the patients. Lung lesions were classified into 4 subtypes: (1) nodules, (2) ground-glass opacity, (3) interstitial-alveolar involvement, and (4) bronchovascular involvement. The presence of pleural involvement and mediastinal adenopathy was also assessed.

Results: We examined data from 28 patients, with 17 (61%) showing pulmonary involvement. The subtypes of pulmonary involvement, in order of frequency, were as follows: type 4 (n = 17, 100%), type 3 (n = 10, 59%), type 2 (n = 6, 36%), and type 1 (n = 5, 29%). Pleural lesions were observed in 2 (12%) cases, and mediastinal adenopathies were found in 4 (23%) cases. No demographic, clinical, or laboratory differences were noted between patients with and without pulmonary involvement, except for serum levels of IgG4, which were higher among patients without pulmonary involvement (339.0 [293.1-1592.1 mg/dL] vs 2869 [1156.3-4037.4 mg/dL]; p = 0.022).

Conclusions: In this case series, the predominant subtype of pulmonary involvement was septal thickening and increased bronchovascular tissue. Patients with and without pleuropulmonary involvement exhibited similar clinical and laboratory manifestations, except for serum IgG4, which was higher in patients without pleuropulmonary involvement.

Background/objective: To determine if anti-RA33 antibodies, which can be seen in early forms of inflammatory arthritis, are present in patients with Lyme arthritis (LA).

Methods: Anti-RA33 antibodies were tested using a commercially available assay in patients with LA (n = 47) and compared with patients with erythema migrans who returned to health (EM RTH, n = 20) and those with post-treatment Lyme disease (PTLD) (n = 50), characterized by noninflammatory arthralgia, as an observational comparative study utilizing Lyme-exposed patients from various original cohorts.

Results: We found that anti-RA33 was present in higher proportions of patients with LA (23.4% vs. 0%, p = 0.001) and PTLD (12.0% vs. 0%, p = 0.040) than healthy controls. There was also a trend toward a higher percentage of anti-RA33 positivity in patients with EM RTH versus controls (10.0% vs. 0%, p = 0.080). There were no statistically significant differences among groups of patients with LA, PTLD, and EM RTH ( p ≥ 0.567). There was also no difference in the proportion of patients with antibiotic-responsive LA compared with those with persistent synovitis after antibiotics, termed post-infectious LA, and there were no differences in clinical manifestations, musculoskeletal ultrasound evaluation (synovial hypertrophy, power Doppler, tendinopathy), or patient-reported outcomes based on anti-RA33 status.

Conclusions: This is the first study to identify anti-RA33 antibodies in patients with LA, though these antibodies did not identify a unique clinical subset of patients in this cohort. Unexpectedly, we found anti-RA33 antibodies at similar levels in patients with PTLD and EM RTH; further study is needed to determine the relevance of this finding.

Background: We aimed to estimate the risk of malignancy associated with ixekizumab in randomized controlled trials (RCTs) and long-term extension studies (LTEs) in patients with rheumatological indications.

Methods: A systematic review of the literature up to June 2024 was performed to analyze the risk of malignancy associated with ixekizumab use in patients with psoriatic arthritis and axial spondyloarthritis. The primary endpoint was overall malignancy risk in RCTs and LTEs. Meta-analyses of RCTs were performed when at least 3 studies had comparable outcome measures using Peto odds ratios. For LTEs, meta-analyses were performed using random-effects computing incidence rates (IRs) per 100 patient-years.

Results: Twelve articles, 4 LTEs and 8 pooled analyses, were included. Meta-analyses of RCTs for malignancy risk at week 24 showed a Peto odds ratio of 0.45 (0.11-1.86), with an I2 of 43.0%. When stratified according to the comparator, heterogeneity decreased. Malignancy risk comparing ixekizumab with placebo was 1.43 (0.18-11.53), with an I2 of 39.6%. Malignancy risk comparing ixekizumab with adalimumab was 0.11 (0.01-0.77), with an I2 of 0%. At week 52, the IR of all malignancies with ixekizumab was 0.31 (0.07-0.72), with an I2 of 18.9%. At 156 weeks, the IR of all malignancies with ixekizumab was 0.58 (0.29-0.96), with an I2 of 0%.

Conclusion: Ixekizumab appears to confer a low malignancy risk in patients treated for rheumatological indications. Patients with psoriatic arthritis and axial spondyloarthritis appeared to be at similar risk, except for those with nonmelanoma skin cancer.

Background/historical perspective: Facial asymmetry has been recognized and represented in Mesoamerican and South American pre-Hispanic cultures.

Summary: This study aims to describe and contextualize an ancient pre-Hispanic stone face carving from the Early Postclassic Period (1200-1500 AD) discovered during excavations for the construction of what is now the National Rehabilitation Institute in Mexico City. The remarkable facial asymmetry of the artifact, suggesting facial paralysis, is a focal point for an interdisciplinary study combining bioarchaeology, anthropology, paleopathology, and rheumatology.

Conclusions: Although most causes of facial paralysis are idiopathic and pre-Hispanic Mesoamerican populations may have had a higher incidence of infections that could be the leading triggering cause, the potential connection between facial paralysis and rheumatic diseases in pre-Hispanic or pre-Columbian contexts is still a topic of ongoing investigation. This task remains highly relevant for rheumatologists who have traced the history and evolution of rheumatic diseases.

Future research: To understand the potential causes of disabilities in ancient societies, a comprehensive, holistic, and transdisciplinary approach is needed, including evidence-based reviews to analyze the relationship between facial paralysis and rheumatic diseases.
