The Role of Pai-1 Gene 4g/5g Polymorphism and Diagnostic Value of Biomarkers in Allergic and Non-Allergic Asthma Phenotype.

Asthma is a chronic inflammatory disease that is characterized by reversible obstruction of airways, bronchial hyper-reactivity and airway remodeling. The etiology of asthma is multifactorial, with inheritance playing an important role. The aim of our study was to investigate the importance of biomarkers of asthma and the role of plasminogen activator inhibitor-1 (PAI-1) gene as a genetic factor that could be involved in the pathogenesis of asthma. The research was conducted at Jordanovac University Department for Lung Diseases and Croatian Institute of Transfusion Medicine. The research included 149 patients with asthma and 89 healthy individuals. We collected demographic data of both study groups, determined asthma severity using GINA guidelines, and the values of biomarkers and PAI-1 by using laboratory techniques. Based on the results, we concluded that patients with allergic phenotype of asthma were younger, had better lung function and higher levels of IgE. By observing FeNO values, we were not able to distinguish asthmatic patients that had been diagnosed with obstruction of airways from asthmatic patients with normal lung function because FeNO indicates the inflammatory component of disease. The 4G/5G polymorphism of PAI-1 gene did not show any statistically significant difference in the distribution of 4G/4G, 4G/5G and 5G/5G between the group of asthmatic patients and control group.

Toxicity by NSAIDs. Counteraction by stable gastric pentadecapeptide BPC 157.

Stable gastric pentadecapeptide BPC 157 is an anti-ulcer peptidergic agent, proven in clinical trials to be both safe in inflammatory bowel disease (PL-10, PLD-116, PL 14736) and wound healing, stable in human gastric juice, with no toxicity being reported. Recently, we claim that BPC 157 may be used as an antidote against NSAIDs. We focused on BPC 157 beneficial effects on stomach, duodenum, intestine, liver and brain injuries, adjuvant arthritis, pain, hyper/hypothermia, obstructive thrombus formation and thrombolysis, blood vessel function, counteraction of prolonged bleeding and thrombocytopenia after application of various anticoagulants and antiplatelet agents and wound healing improvement. The arguments for BPC 157 antidote activity (i.e., the role of BPC 157 in cytoprotection, being a novel mediator of Robert's cytoprotection and BPC 157 beneficial effects on NSAIDs mediated lesions in the gastrointestinal tract, liver and brain and finally, counteraction of aspirin-induced prolonged bleeding and thrombocytopenia) obviously have a counteracting effect on several established side-effects of NSAIDs use. The mentioned variety of the beneficial effects portrayed by BPC 157 may well be a foundation for establishing BPC 157 as a NSAIDs antidote since no other single agent has portrayed a similar array of effects. Unlike NSAIDs, a very high safety (no reported toxicity (LD1 could be not achieved)) profile is reported for BPC 157. Also, unlike the different dosage levels of aspirin, as a NSAIDs prototype, which differ by a factor of about ten, all these beneficial and counteracting effects of BPC 157 were obtained using the equipotent dosage (µg, ng/kg) in parenteral or peroral regimens.
