Stem Cell Treatment for Lung Injury Caused by Major Infectious Diseases

Status Recruiting

Clinical Trial Summary

The goal of this study is to conduct a prospective, double-blind, randomized placebo-controlled clinical trial to investigate the safety and efficacy of mesenchymal stem cells treatment for Lung injury caused by major infectious diseases.

Clinical Trial Description

For patients with lung injury caused by major infectious diseases, conventional antiviral and anti-inflammatory treatments may not effectively improve lung function in the short term and may increase the risk of secondary infections. Therefore, in the clinical management of viral pneumonia, it is necessary to consider the lung tissue damage caused by acute viral replication and systemic immune stress, while also focusing on the subsequent lung functional impairment due to virus clearance-induced pulmonary fibrosis. Studies have shown that after peripheral intravenous administration of mesenchymal stem cells (MSCs), approximately 50% to 60% of the cells remain in the lung tissue within 1 hour, decreasing to around 30% after 3 hours. After 48 hours, MSCs tend to aggregate in the liver and spleen, and cell retention can still be detected 10 days later. MSCs aggregation in the lung tissue can secrete cell trophic factors such as keratinocyte growth factor (KGF), vascular endothelial growth factor (VEGF), and hepatocyte growth factor (HGF), promoting the regeneration of type II alveolar epithelial cells, improving the pulmonary microenvironment, and facilitating the repair of the alveolar epithelial barrier after ARDS injury.This study is intended to conduct a prospective, double-blind, randomized placebo-controlled clinical trial to investigate the safety and efficacy of mesenchymal stem cells treatment for Lung injury caused by major infectious diseases. ;
