We studied the relationship between the histopathology obtained by trans-bronchial lung biopsy (TBLB), and spirometric indices in 28 patients of pulmonary sarcoidosis in whom the diagnosis was confirmed. There was a rough correlation between FVC and the histologic granuloma load, interstitial inflammation and the overall histopathological score. Radiological features did not correlate with either spirometry or histopathology.

Interstitial lung disease (ILD) has shown limited treatment advancements, with minimal exploration of circulating protein biomarkers causally linked to ILD and its subtypes beyond idiopathic pulmonary fibrosis (IPF). In this study, we aimed to identify potential drug targets and circulating protein biomarkers for ILD and its subtypes. We utilized the most recent large-scale plasma protein quantitative trait loci (pQTL) data detected from the antibody-based method and ILD and its subtypes' GWAS data from the updated FinnGen database for Mendelian randomization analysis.

Background: Diagnosis of sarcoidosis often involves endobronchial biopsy (EBB), but studies have shown varying yields for EBB in suspected sarcoidosis, partly due to differences in identifying abnormal mucosa under white light (WL). Narrow band imaging (NBI) may assist in the visualization of abnormal mucosa, but its role in sarcoidosis remains to be characterized.
Methods: Individuals referred for suspected sarcoidosis were considered for enrollment.

Sarcoidosis is a chronic granulomatous disease with multisystemic involvement with unspecified aetiology. Pancreatic involvement is a rare manifestation of systemic sarcoidosis and is often detected in postmortem studies. This clearly implies the rarity of the disease and its diagnostic challenges.

Background: In a phase 1b/2a clinical trial of efzofitimod in patients with corticosteroid-requiring pulmonary sarcoidosis, treatment resulted in dose-dependent improvement in key end-points. We undertook a analysis pooling dose arms that achieved therapeutic concentrations of efzofitimod (Therapeutic group) those that did not (Subtherapeutic group).
Methods: Peripheral blood mononuclear cells incubated with tuberculin-coated beads were exposed to varying concentrations of efzofitimod in an assay to determine concentrations that inhibited granuloma formation.

Sarcoidosis is a systemic granulomatous disease of unknown etiology, primarily affecting the lungs and the lymphatic system. Its diagnosis is challenging, and in many cases, it requires histopathological confirmation through the identification of non-caseating granulomas. The presented case illustrates its diagnostic complexity and highlights a rare, delayed complication associated with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).
