Article Abstract
Objectives: To assess the value of serum ferritin and Krebs von den Lungen-6 (KL-6) levels for predicting severe COVID-19 (death or requirement for invasive mechanical ventilation [IMV]/high-flow oxygen).
Methods: Data were analyzed on 2495 patients with COVID-19 from February 2020 to November 2022 using data from a nationwide COVID-19 database.
Results: Patients with high KL-6 and low ferritin levels were older with more comorbidities and higher mortality rates, whereas those with high ferritin and low KL-6 levels were younger, predominantly male, and more likely to need IMV. A high level of both markers was strongly associated with critical outcomes (adjusted odds ratio: 13.6, 95% confidence interval: 8.58-21.5). The combination of both markers had higher predictive value than either marker alone (area under the curve: 0.709, 0.745, and 0.781 for KL-6, ferritin, and KL-6 + ferritin, respectively).
Conclusions: The combination of both markers accurately predicted COVID-19 severity.

Diagnostic efficacy of serum Krebs von den Lungen-6 for dermatomyositis/polymyositis-associated interstitial lung diseases: A systematic review and meta-analysis.

Background: Previous studies have reported inconsistent findings regarding the diagnostic role of Krebs Von den Lungen-6 (KL-6) in dermatomyositis/polymyositis-associated interstitial lung disease (PM/DM-ILD) and its correlation with disease severity. This meta-analysis aimed to evaluate the diagnostic efficacy of serum KL-6 in detecting DM/PM-ILD and its association with pulmonary function.
Methods: In April 2023, we systematically searched PubMed, Web of Science, Cochrane Library, CNKI, Wan Fang, and VIP databases to identify studies investigating the association of KL-6 with DM/PM-ILD.
A comparative analysis of clinical phenotypes and outcomes in childhood interstitial lung disease due to surfactant dysfunction disorders: focusing on mutations in SFTPC, ABCA3, and NKX2-1 genes.

Background: Surfactant dysfunction disorders are a group of rare diseases that lead to childhood interstitial lung diseases (ILD). SFTPC, ABCA3, and NKX2-1 are the three genetic forms of this condition. The differences in clinical presentations and prognostic outcomes across these genotypes are not well understood, warranting comparative analysis.

To analyze the clinical characteristics of anti-melanoma differentiation associated gene 5 (MDA5) antibody-positive juvenile dermatomyositis (JDM) patients. A retrospective case-control study was conducted. The positive group included 18 children with anti-MDA5 antibody-positive JDM who were admitted to the Department of Rheumatology and Immunology at Capital Center for Children's Health with Capital Medical University between January 2016 and January 2023.

Objective: To comprehensively characterize clinical features, diagnostic challenges, and prognostic biomarkers of anti-MDA5 antibody-positive dermatomyositis (MDA5-DM), incorporating transcriptomic analysis to elucidate underlying molecular mechanisms.
Methods: We conducted a retrospective analysis of 29 MDA5-DM patients, collecting detailed clinical and laboratory data. Prognostic factors were identified using LASSO regression, validated by Cox proportional hazards and Kaplan-Meier survival analyses.

Background: Interstitial lung disease (ILD) is a severe complication affecting 10-30% of rheumatoid arthritis (RA) patients. Current diagnostic methods typically detect ILD only after substantial lung damage has occurred. This delay emphasizes the need for early detection strategies.
