The patient was a 69-year-old man with idiopathic pulmonary fibrosis who was taking pirfenidone. After 7 weeks of treatment, he suffered from left-sided eosinophilic pleurisy. Medical thoracoscopy was performed and the histopathological examination of the parietal pleura revealed the massive infiltration of eosinophils and lymphoid follicles. After stopping pirfenidone therapy, the patient's pleural effusion disappeared without additional treatment, and never recurred. This is the first case report of pirfenidone-induced pleurisy...

Recently the FDA approved the first two drugs (pirfenidone and nintedanib) indicated for the treatment of idiopathic pulmonary fibrosis (IPF). The purpose of this analysis was to leverage publicly available data to quantify comparative efficacy of compounds that are approved or in development. An analysis-ready database was developed, and the analysis dataset is composed of summary-level data from 43 arms in 20 trials, with treatment durations ranging from 8 to 104 weeks. A hierarchical multivariable regression model with non-parametric placebo estimation was used to fit the longitudinal profile of change from baseline of percent predicted forced vital capacity (%predicted FVC) data...

BACKGROUND: Inhalation drug delivery is a fast, effective, and safe route of delivering medication directly to the lungs. Thanks to the large surface area and highly vascularized epithelium in lung, pulmonary drug delivery has been considered as an effective route to deliver drugs to the systemic circulation. Pirfenidone (PF), an oral antifibrotic agent, has been shown to slow down the progression of the lung fibrosis. Inhalation or intrapulmonary delivery of PF appears to be a good alternative to optimize drug delivery and minimize the dosage, adverse and nonspecific effects...

The epithelial-to-mesenchymal transition (EMT) in cancer is associated with invasion, metastasis and chemoresistance. Recent studies have revealed the increased expression of programmed death-ligand 1 (PD-L1) in cells undergoing EMT. The underlying mechanism of EMT involves transforming growth factor-β (TGF-β) and fibroblast growth factor-2 (FGF-2). Pirfenidone and the known EMT-suppressor nintedanib suppress pulmonary fibrosis partially through suppression of TGF-β. The present study aimed to determine whether pirfenidone has the potential to induce EMT-reversion, using nintedanib as a reference...

In vivo phototoxicity studies are important to predict drug-induced phototoxicity in humans; however, a standard methodology has not established. To determine differences in sensitivity to drug-induced phototoxicity among various skin sites, we evaluated phototoxic reactions in the back and abdominal skin of female Sprague-Dawley rats orally dosed with phototoxic drugs (pirfenidone, 8-methoxysoraren, doxycycline, and lomefloxacin) or a non-phototoxic drug (gatifloxacin) followed by solar-simulated light irradiation comprising 18J/cm(2) ultraviolet A...

Pulmonary fibrosis (PF) is a lethal, chronic and progressive respiratory disease leading to interstitial lung damage and serious breathing problems. The pathogenic mechanism involves activation, migration, proliferation and differentiation of fibroblasts into myofibroblats inducing extracellular matrix accumulation that destroy lung parenchyma. Available antifibrotic treatment options are limited to Pirfenidone and Nintedanib that prevent deterioration without an improvement of this disease. The use of plant extracts and natural bioactive compounds for the treatment of PF has been known for more than thirty years in China...

Objective Depression is reported to be relatively common in idiopathic pulmonary fibrosis (IPF) patients. Thus far, however, whether or not depression independently determines the health-related quality of life (HRQOL) has not been evaluated exclusively in IPF patients. We designed this study to identify independent determinants of the St. George' s Respiratory Questionnaire (SGRQ) score among various factors, including a depression scale, in IPF patients. Methods We retrospectively analyzed consecutive subjects with IPF who completed a systematic evaluation including pulmonary function tests, PaO2 at rest, 6-minute walk test (6MWT), SGRQ, Baseline Dyspnea Index (BDI), and Hospital Anxiety and Depression Scale (HADS)...

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease that up to now has been associated with a poor prognosis. However, the results of the INPULSIS and ASCEND trials and the approval of nintedanib and pirfenidone have marked the beginning of a new era for IPF patients. Questions remain, however. Should these drugs be used earlier? What effect will they have on more severe disease? Will their effects last beyond the trial period? This manuscript is the outcome of a multidisciplinary meeting between pulmonology, radiology, and pathology clinicians on the use of antifibrotic agents in IPF...

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and debilitating lung disease with a median survival time of 3-5 years. For now, pirfenidone (PIR) and nintedanib (NTB) are the only drugs that can slow down the disease's progression. In Poland, these drugs, although registered for legal use, had not been reimbursed for IPF patients until the end of the year 2016. Aim of the study was to assess what was common practice in terms of diagnosis and treatment in the period before antifibrotic drugs became available for IPF patients in Poland...

BACKGROUND AND PURPOSE: Src-homology 2 domain-containing inositol-5-phosphatase 1 is a negative regulator of the phosphoinositide-3-kinase (PI3K) pathway and its predominant expression within cells of the hematopoietic compartment make SHIP1 activation a novel strategy to limit inflammatory signaling generated through PI3K. AQX-1125 is the only clinical-stage, orally administered, SHIP1 activator with demonstrated anti-inflammatory effects in animals and humans. This work demonstrates the prophylactic and therapeutic effects of AQX-1125, in the mouse model of bleomycin-induced lung fibrosis...

Pirfenidone is an anti-inflammatory and anti-fibrotic drug that has shown efficacy in lung and kidney fibrosis. Because inflammation and fibrosis have been linked to the progression of osteoarthritis, we investigated the effects of oral Pirfenidone in a mouse model of cartilage injury, which results in chronic inflammation and joint-wide fibrosis in mice that lack hyaluronan synthase 1 (Has1(-/-) ) in comparison to wild-type. Femoral cartilage was surgically injured in wild-type and Has1(-/-) mice, and Pirfenidone was administered in food starting after 3 days...

A new scoring system based on histo-morphology of mouse intervertebral disc (IVD) was established to assess changes in different mouse models of IVD degeneration and repair. IVDs from mouse strains of different ages, transgenic mice, or models of artificially-induced IVD degeneration were assessed. Morphological features consistently observed in normal, and early/later stages of degeneration were categorised into a scoring system focused on nucleus pulposus (NP) and annulus fibrosus (AF) changes. "Normal NP" exhibited a highly cellularised cell mass that decreased with natural ageing and in disc degeneration...

Pharmacological modulation of responses to injury is complicated by the need to deliver multiple drugs with spatiotemporal resolution. Here, a novel controlled delivery system containing three separate compartments with each releasing its contents over different timescales is fabricated. Core-shell electrospun fibers create two of the compartments in the system, while electrosprayed spheres create the third. Utility is demonstrated by targeting the foreign body response to implants because it is a dynamic process resulting in implant failure...

PURPOSE OF REVIEW: Therapeutic advances in the management of idiopathic pulmonary fibrosis (IPF) has led to improved outcomes with the use of the antifibrotic agents pirfenidone and nintedanib, with a number of randomized studies demonstrating benefits in slowing disease progression in IPF. However, treatment of other fibrosing interstitial lung diseases (ILD) remains challenging. RECENT FINDINGS: Observational and uncontrolled studies investigating pirfenidone and nintedanib in non-IPF ILDs suggest potential benefits, although the data is weak...

This paper outlines a treatment protocol to run alongside of standard current treatment of glioblastoma- resection, temozolomide and radiation. The epithelial to mesenchymal transition (EMT) inhibiting sextet, EIS Regimen, uses the ancillary attributes of six older medicines to impede EMT during glioblastoma. EMT is an actively motile, therapy-resisting, low proliferation, transient state that is an integral feature of cancers' lethality generally and of glioblastoma specifically. It is believed to be during the EMT state that glioblastoma's centrifugal migration occurs...

Abdominal surgery is linked with peritoneal adhesions. We investigated that the anti-fibrotic agent pirfenidone (PFD) has immune modulating activities and evaluated its effects on the function of T helper type 1 (Th1), Th2 and T regulatory (Treg) cells, which may play important roles in peritoneal adhesions. Eighteen female Wistar rats underwent right-sided parietal peritoneal and right uterine horn adhesion model. Rats were randomized into 3 groups as group 1 (control) (closure of midline abdominal incision without any agent administrations), group 2 (closure of incision after intraperitoneal administration of PFD) and group 3 (closure of incision and only oral administration of PFD for 14 days)...

Tracheal stenosis (TS) is a fibrosis originated by prolonged inflammation and increased transforming growth factor beta 1 (TGF-β1) expression and collagen deposition (CD) in the tracheal wound. Several wound-healing modulators (WHMs) have been used to modulate the tracheal healing process and prevent TS, but they have failed, justifying the need to evaluate alternative WHM. The pirfenidone (PFD) and collagen-polyvinylpyrrolidone (Collagen-PVP) decrease inflammation and fibrosis. This study assessed the effect of PFD administration and Collagen-PVP topical application on macroscopic and microscopic changes, TGF-β1 expression, and CD in an experimental model of tracheal wound healing...

BACKGROUND: Pirfenidone (PFD) is an anti-fibrotic agent used to treat idiopathic pulmonary fibrosis (IPF), but its precise mechanism of action remains elusive. Accumulation of profibrotic myofibroblasts is a crucial process for fibrotic remodeling in IPF. Recent findings show participation of autophagy/mitophagy, part of the lysosomal degradation machinery, in IPF pathogenesis. Mitophagy has been implicated in myofibroblast differentiation through regulating mitochondrial reactive oxygen species (ROS)-mediated platelet-derived growth factor receptor (PDGFR) activation...
