Introduction: The radiology pattern associated with IPF is called UIP. It is unique because unlike any other form of fibrosis it is peripheral in its distribution. We investigated the peripheral nature of UIP and why it was a key feature of IPF the deadliest of the ILDS.
Areas Covered: It is not enough to say that UIP is peripheral but instead as scientists we must ask ourselves why it is peripheral. This review dives into the published hypothesis that includes vascular insult, tensile forces, microaspiration, and inflammation and looks at the pros and cons for each argument, and ultimately comes to its own conclusion. PubMed searches using the below keywords were used to identify papers that described pathogenesis of IPF with regard to a particular theory.
Expert Opinion: In this paper, we will review four ideas that support why UIP is peripheral and propose the most likely explanation given what is currently known about the pathophysiology of IPF.

Safe surgical lung biopsy in the diagnosis of interstitial lung disease under strict patient selection.
Respir Investig
January 2025
Division of First Department of Surgery, Hamamatsu University School of Medicine, 1-20-1 Handayama, Chuo Ward, Hamamatsu, Shizuoka, 431-3192, Japan. Electronic address:
Article Synopsis
- - This study evaluates the safety of surgical lung biopsy (SLB) for diagnosing idiopathic pulmonary fibrosis by excluding high-risk patients from the analysis.
- - A retrospective review of 94 patients showed a median age of 66 years, with no reported mortality at 30 or 90 days post-surgery, and only 1% experiencing an acute exacerbation.
- - The criteria for patient selection appear valid, indicating that SLB can be performed safely when specific high-risk factors are excluded.
Location of Fibroblastic Foci: Does the Lesion You Observe Really Suggest Usual Interstitial Pneumonia?
Mod Pathol

Department of Diagnostic Pathology, Kyoto University Hospital, Kyoto, Japan; Department of Diagnostic Pathology, Nara Medical University, Nara, Japan.
Article Synopsis
- Fibroblastic foci (FF) are important indicators of usual interstitial pneumonia (UIP) but can also appear in various fibrotic interstitial lung diseases (ILDs), making them non-specific for UIP.
- This study analyzed the spatial distribution of FF in different forms of ILDs in patients who underwent lung transplants, categorizing them by anatomical location.
- Results showed that idiopathic pulmonary fibrosis (IPF) had more total and peripheral FF compared to other ILDs, while centrilobular FF was more prevalent in fibrotic hypersensitivity pneumonitis (FHP), suggesting distinct spatial patterns associated with different diseases.
High resolution computed tomography in systemic sclerosis: From diagnosis to follow-up.
Rheumatol Immunol Res
September 2024
Department of Medicine and Surgery, University of Parma, Parma, Italy.
Article Synopsis
- - Early diagnosis of interstitial lung disease (ILD) and pulmonary hypertension (PH) in systemic sclerosis (SSc) is vital for effective management, but symptoms can be vague in the early stages, making diagnosis difficult.
- - High-resolution computed tomography (HRCT) is the best imaging technique for evaluating SSc-ILD, showing key features like non-specific interstitial pneumonia (NSIP), ground-glass opacities, and traction bronchiectasis.
- - Monitoring disease progression and treatment response through serial HRCT assessments is essential, as the extent of disease visible on scans correlates with patient prognosis.
Chemokine receptor CXCR4 based positron emission tomography imaging in systemic sclerosis-related interstitial lung disease.
Rheumatology (Oxford)
September 2024
Division of Clinical Immunology and Rheumatology, Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, Chandigarh, India.
Objective: To assess chemokine receptor CXCR4 expression in lung parenchyma and on peripheral immune cells in systemic sclerosis-related interstitial lung disease (SSc-ILD) patients.
Methods: SSc-ILD patients underwent 68Ga- CPCR4 Trifluoroacetate positron emission tomography (PET) scan, SUVmean in different lung regions and architecturally abnormal areas, and receiver operating characteristic (ROC) curves were analyzed. CXCR4 expression on peripheral immune cells using flow cytometer was studied and correlated with the different lung regions.
Serum Concentrations of Chemokines CCL20, CXCL8 and CXCL10 in Relapsing-Remitting Multiple Sclerosis and Their Association with Presence of Antibodies against Epstein-Barr Virus.

Epstein-Barr virus (EBV) infection and various chemokines, including CCL20, CXCL8 and CXCL10 are considered to participate in the pathogenesis of multiple sclerosis (MS), and several studies point to a direct regulatory effect of EBV on the expression of these chemokines. In our study we hypothesized that serum concentrations of CCL20, CXCL8 and CXCL0 are induced in patients with relapsing-remitting MS (RRMS) in comparison to healthy individuals, and that they are associated with EBV infection. Serum concentrations of CXCL8 and CXCL10 were lower in RRMS patients in relapse in comparison to healthy controls.
