Pharmacological treatment in Idiopathic Pulmonary Fibrosis: current issues and future perspectives.

Idiopathic pulmonary fibrosis (IPF) represents a fibrotic interstitial lung disease characterized by uncertain etiology and poor prognosis. Over the years, the path to effective treatments has been marked by a series of advances and setbacks. The introduction of approved antifibrotic drugs, pirfenidone and nintedanib, marked a pivotal moment in the management of IPF.

Melatonin Enhances Neural Differentiation of Adipose-Derived Mesenchymal Stem Cells.

Adipose-derived mesenchymal stem cells (ASCs) are adult multipotent stem cells, able to differentiate toward neural elements other than cells of mesodermal lineage. The aim of this research was to test ASC neural differentiation using melatonin combined with conditioned media (CM) from glial cells. Isolated from the lipoaspirate of healthy donors, ASCs were expanded in a basal growth medium before undergoing neural differentiation procedures.

Clinical and Prognostic Significance of p-ANCA Positivity in Idiopathic Pulmonary Fibrosis: A Retrospective Observational Study.

Perinuclear Anti Neutrophil Cytoplasmic Antibody (p-ANCA) is a serological marker of Microscopic Polyangiitis (MPA), a vasculitis associated with lung involvement potentially mimicking Idiopathic Pulmonary Fibrosis (IPF). In this study, we evaluated the role of p-ANCA in predicting clinical evolution and prognosis in a cohort of IPF patients. In this observational, retrospective, case-control study, we compared 18 patients with an IPF diagnosis and p-ANCA positivity with 36 patients with seronegative IPF, matched for age and sex.

Myositis-Specific and Myositis-Associated Antibodies in Fibromyalgia Patients: A Prospective Study.

Fibromyalgia (FM) is a common rheumatologic disorder characterised by widespread muscular pain. Myalgia is also a common clinical feature in Connective Tissue Disease (CTD), and FM should be studied for the concomitant presence of a CTD. The aim of this study is to evaluate the prevalence of Myositis-Specific and Myositis-Associated Antibodies (MSA/MAA) in a cohort of FM patients.

Developing PI3K Inhibitors for Respiratory Diseases.

A number of different experimental models using both non-selective and selective PI3K inhibitors have shown that many pathogenic steps of respiratory disorders, such as bronchial asthma, Chronic Obstructive Pulmonary Disease (COPD), Idiopathic Pulmonary Fibrosis (IPF), Acute Respiratory Distress Syndrome (ARDS) and Lung Cancer (LC) are, at least in part, regulated by the PI3K signaling pathway, suggesting that the inhibition of PI3K could represent an ideal therapeutic target for the treatment of respiratory diseases. This chapter summarizes the current state of the therapeutic strategies aimed to exploit the inhibition of PI3K in this context. In animal models of asthma, selective δ and γ inhibitors have shown to be effective, and when administered by inhalation, reasonably safe.
