Abstract
Idiopathic pulmonary fibrosis is a lethal, progressive, and irreversible condition that has become a significant focus of medical research due to its increasing incidence. This rising trend presents substantial challenges for patients, healthcare providers, and researchers. Despite the escalating burden of pulmonary fibrosis, the available therapeutic options remain limited. Currently, the United States Food and Drug Administration has approved two drugs for the treatment of pulmonary fibrosis-nintedanib and pirfenidone. However, their therapeutic effectiveness is limited, and they cannot reverse the fibrosis process. Additionally, these drugs are associated with significant side effects. Myofibroblasts play a central role in the pathophysiology of pulmonary fibrosis, significantly contributing to its progression. Consequently, strategies aimed at inhibiting myofibroblast differentiation or promoting their dedifferentiation hold promise as effective treatments. This review examines the regulation of myofibroblast dedifferentiation, exploring various signaling pathways, regulatory targets, and potential pharmaceutical interventions that could provide new directions for therapeutic development.

A phase II investigator-initiated pilot study with low-dose cyclosporine A for the treatment of articular involvement in primary Sjögren's syndrome. Clin Rheumatol 2016; 35:2203-10. [PMID: 27470087 DOI: 10.1007/s10067-016-3360-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2016] [Revised: 07/15/2016] [Accepted: 07/15/2016] [Indexed: 11/30/2022]
Abstract
UNLABELLED This study aims to investigate the efficacy and safety of low-dose cyclosporine A (CyA) in patients with primary Sjögren's syndrome (pSS) and articular involvement. This phase II open-label clinical study included 30 patients meeting the American-European Consensus group criteria for pSS with active joint involvement under stable symptomatic therapy. Treatment consisted of approximately 2 mg kg(-1) body weight of CyA day(-1) over a period of 16 weeks. The primary endpoint was defined as a reduction in the number of painful and/or swollen joints at end of treatment (EOT). Secondary endpoints included the changes in general health, sicca symptoms, European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI), arthrosonography, and safety profile. At baseline (BL), the mean number of tender joints (68 count) was 16.2 (±13.2) and at EOT 10.4 (±11.9; p = 0.002). The mean number of swollen joints (66 counts) was reduced from 3.2 (±3.3) at BL to 1.3 (±3.2) at EOT (p < 0.001). Overall, 21 (70 %) and 13 (43.3 %) patients had a reduction of two or more tender and swollen joints, respectively, in the 68/66 joint counts. The disease activity score (DAS28) showed a statistically and clinically meaningful decrease over the 16-week period of treatment. Treatment was well tolerated, and adverse events were consistent with the known safety profile of CyA (e.g., hypertension, headache). In this pilot study, promising effects of low-dose CyA treatment on articular involvement were observed in patients with pSS justifying further controlled studies in this indication. No new or unexpected safety observations were made. TRIAL REGISTRATION Low-Dose Cyclosporin A in Primary Sjögren Syndrome (CYPRESS), ClinicalTrials.gov Identifier: NCT01693393 .

Abstract
BACKGROUND Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is considered to be a nearly fatal condition during the clinical course of IPF, as it is unresponsive to most conventional therapies. SUBJECTS AND METHODS To evaluate the efficacy of cyclosporin A (CsA) for AE of IPF, we conducted a retrospective study on autopsied IPF cases who developed AE and were treated with corticosteroids (CS) combined with CsA. The subjects comprised 11 males with a mean age of 69.9 years. The clinical features and prognosis of the CsA-treated group was compared to a group of 11 autopsied IPF cases with a mean age of 68.7 years who developed AE and were treated with CS alone (non-CsA-treated group). RESULTS CS pulse therapy followed by CS maintenance treatment were conducted in all cases of AE. Patients in the CsA-treated group received in addition a low dosage of CsA (100-150 mg). Although 7 out of 11 patients in the CsA-treated group died of AE per se, 4 patients survived the AE. Only 2 patients died during the first episode of AE. In comparison, 7 out of 11 patients in the non-CsA-treated group died during the first episode of AE. The mean survival period after the first onset of AE was 285 days in the CsA-treated group and 60 days in the non-CsA-treated group. The prognosis of the CsA-treated group therefore was significantly better than that of non-CsA-treated group after AE of IPF. CONCLUSION Administration of CsA combined with CS may be efficacious in the treatment of AE of IPF.
