: Anti-neutrophil cytoplasmic antibodies (ANCAs) have been found in interstitial lung disease (ILD) in recent years, although its impact on ILD prognosis is less known. To date, ANCAs are not included in the interstitial pneumonia with autoimmune features (IPAF) definition criteria. Therefore, ANCA-ILD, in the absence of known ANCA-associated vasculitis (AAV), could be underdiagnosed.

Patients with rheumatic immune-mediated diseases (rheumatic-IMID) and latent tuberculosis (LTBI) are at an increased risk of developing active tuberculosis (TB); therefore, screening is recommended before starting biological treatment. The aims of this study were as follows: (i) to assess the prevalence of LTBI, (ii) to determine the importance of using a booster test in TST-negative patients, (iii) to compare the tuberculin skin test (TST) with the interferon-gamma release assay (IGRA), (iv) to perform a review of the prevalence of LTBI. A cross-sectional hospital study was performed, including patients diagnosed with rheumatic-IMID who underwent a TST and/or IGRA during the period 2016-2020.

Background: Racial and ethnic disparities have been reported for HCC prognosis, although few studies fully account for clinically important factors and social determinants of health, including neighborhood socioeconomic status.

Methods: We conducted a retrospective multicenter cohort study of patients newly diagnosed with HCC from January 2010 through August 2018 at 4 large health systems in the United States. We used multivariable logistic regression and cause-specific Cox proportional hazard models to identify factors associated with early-stage HCC presentation and overall survival.

Objetive: To evaluate the frequency and timing of sustained drug-free remission (SDFR) in patients with giant cell arteritis (GCA) and to identify potential predictive factors of this outcome.

Methods: Retrospective review of all patients included in the large Spanish multicentre registry for GCA (ARTESER) with at least two years of follow-up. SDFR was defined as the absence of typical signs, symptoms, or other features of active GCA for ≥12 months after discontinuation of treatment.

Parasitic infections are a major global health challenge, driven in part by complex interactions between parasites, host microbiota, and immune responses. Recent advances in microbiome research highlight the critical role of microbiota in influencing disease outcomes and treatment effectiveness. This review examines how changes in the microbiota impact parasite transmission, disease progression, and responses to treatment, focusing on key parasitic diseases such as Chagas disease, leishmaniasis, and ascariasis.

The complex interactions between parasites, their hosts, and associated microbiota hold significant implications for host health and disease outcomes. Helminths like Ascaris lumbricoides and Ascaris suum can significantly alter the host's intestinal microbiota, affecting both parasite biology and host pathology. Despite extensive research on host-microbiota changes due to helminth infections, the study of helminth-associated microbiota remains limited.

IgA vasculitis (IgAV), previously named as Henoch-Schönlein purpura, is the most frequent systemic vasculitis in children. In adults, IgAV is less common although it is associated with more severe disease. In fact, the frequency of glomerulonephritis (referred to as IgAV nephritis) in adults is higher than in children and tends to present more severely, with around 10-30% of those affected eventually progressing to end-stage renal disease.

Article Synopsis
  • Polymyalgia Rheumatica (PMR) is an inflammatory condition commonly affecting people over 50, with glucocorticoids being the main treatment despite their side effects and risk of relapses upon tapering.
  • This review explores traditional PMR management and highlights emerging therapies, especially glucocorticoid-sparing agents like methotrexate and biologic agents, which show promise in reducing glucocorticoid use and managing the disease effectively.
  • The effectiveness of biologics, particularly anti-IL-6 receptor agents such as tocilizumab and sarilumab, has been noted for their ability to decrease relapse rates and help achieve long-term remission in PMR patients.

The Millennium Cohort Study is a longitudinal study which collects self-reported data from surveys to examine the long-term effects of military service. Participant nonresponse to follow-up surveys presents a potential threat to the validity and generalizability of study findings. In recent years, predictive analytics has emerged as a promising tool to identify predictors of nonresponse.

Imaging studies have transformed the diagnosis of large vessel vasculitis (LVV) involvement in giant cell arteritis (GCA). A positron emission tomography/computed tomography (PET/CT) scan with 18-fluorodeoxyglucose (18F-FDG) has emerged as a valuable tool for assessing LVV. We aimed to determine the utility of an 18F-FDG-PET/CT scan in detecting LVV in GCA in the ARTESER registry.

Introduction: Although posttraumatic stress disorder (PTSD) and depression are prominent mental health conditions affecting United States service members, only a subset of individuals with these conditions utilize mental healthcare services. Identifying factors associated with mental healthcare utilization may elucidate military subgroups with unmet mental healthcare needs.

Methods: Cross-sectional survey data from the 2019-2021 Millennium Cohort Study assessment were used to examine correlates of unmet mental healthcare needs among military personnel who screened positive for PTSD or depression symptoms (n=18,420) using modified Poisson regression models.

  • * Researchers genotyped 552 SNPs in genes related to bone health in 268 patients, using data from the PEARL study, and analyzed their connection to BMD using linear regression.
  • * Significant associations were found between specific SNPs in the RANK and OPG genes with clinical severity and BMD; one SNP (rs1805034) was highlighted as a potential biomarker for severity in rheumatoid arthritis patients.

  • - Neuro-Behçet's disease (NBD) is a serious complication of Behçet's disease (BD), and a study in Northern Spain aimed to estimate its current incidence from 1999 to 2019 based on 120 patients diagnosed with BD using international criteria.
  • - A total of 96 patients were analyzed, with NBD diagnosed in 24% of them; the average age was 44 years, and genetic testing showed HLA-B51 positivity in about 38% of the cases.
  • - The incidence rate of NBD during the study was found to be 0.13 per 100,000 people-years, with no significant gender differences and a trend towards earlier diagnosis over time,

  • The genetic factors contributing to stroke risk in South Asians remain largely unstudied, with a recent study examining 75,000 Pakistanis using exome-wide sequencing.
  • A specific genetic variant, NOTCH3 p.Arg1231Cys, was found to be more common in South Asians (0.58%) compared to Western Europeans (0.019%) and was significantly linked to hemorrhagic and overall stroke risk.
  • This variant accounts for about 2.0% of hemorrhagic strokes and 1.1% of all strokes in South Asians, emphasizing the importance of including diverse populations in genetic research for better understanding and treatment of stroke.

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease characterized by severe organ damage and lacking curative treatment. While various immune cell types, especially dysfunctional B and T cells and neutrophils, have been related with disease pathogenesis, limited research has focused on the role of monocytes in SLE. Increased DNA extracellular traps, apoptosis and necrosis have been related to lupus pathogenesis.

Malaria and babesiosis are global health threats affecting humans, wildlife, and domestic animals, particularly in Africa, the Americas, and Europe. Malaria can lead to severe outcomes, while babesiosis usually resembles a mild illness but can be severe and fatal in individuals with weakened immune systems. Swift, accurate detection of these parasites is crucial for treatment and control.
