Study Description
Brief Summary:

Although the advent of advanced medical support for respiratory failure, the mortality rate of acute severe respiratory failure is still high and the life quality is frequently compromised from pulmonary fibrosis.

The investigators hypothesize that the treatment using mesenchymal stem cell can be beneficial in patients with respiratory failure. The present study is a pilot study evaluating the efficacy and safety of mesenchymal stem cell treatment in patients with respiratory failure.


Condition or disease Intervention/treatment Phase
Respiratory Distress Syndrome, Adult Biological: Mesenchymal Stem Cell Phase 2

Detailed Description:

Although the advent of advanced medical support for respiratory failure, the mortality rate of acute severe respiratory failure is still reported to be more than 40%. The respiratory distress syndrome may develop in all ages resulting in progressive pulmonary fibrosis. A number of survivors from respiratory failure suffer from the sequelas of pulmonary fibrosis.

However, the treatments of respiratory failure are limited to the correction of baseline disease, cardiopulmonary support, and conservative management to minimize the lung injury. There has not been any effective and specific treatment for respirator distress nor medicine to reduce mortality.

There have been reports of mesenchymal stem cell experimental animals with chronic obstructive pulmonary disease, interstitial lung disease, and sepsis. In addition, the mesenchymal stem cell treatment showed beneficial effect in bleomycin endotoxin induced lung injury.

Authors hypothesize that the mesenchymal stem cell treatment in patients with respiratory failure will show efficacy. We would conduct the present pilot study to evaluate the efficacy and safety in patients with respiratory failure and intend to suggest an additional alternative treatment option for those without additional treatment option.

Outcome Measures

Primary Outcome Measures :
  1. Oxygen index at 3 days after mesenchymal stem cell infusion [ Time Frame: 3 days after mesenchymal stem cell infusion ]
    Oxygen index at 3 days after mesenchymal stem cell infusion. Oxygen index is calculated as follows; ((FiO2) x (Mean airway pressure)) / (PaO2)


Secondary Outcome Measures :
  1. Lung mechanics [ Time Frame: at 3, 14, and 28 days after mesenchymal stem cell infusion ]
    Lung mechanics includes arterial oxygen saturation, tidal volume, minute ventilation, and ratio of PaO2/FiO2.

  2. Hemodynamic parameters [ Time Frame: at 3, 14, and 28 days after mesenchymal stem cell infusion ]
    Systolic, diastolic, and mean arterial blood pressure Amount of required vasopressor Heart rate

  3. Mortality [ Time Frame: at 14 and 28 days after mesenchymal stem cell infusion ]
    Death from any cause at 14 and 28 days after mesenchymal stem cell infusion

  4. Plasma cytokines [ Time Frame: at 3, 14, and 28 days after mesenchymal stem cell infusion ]
    Interleukin (IL)-1, IL-6, IL-8, and IL-10

  5. Markers for inflammation and infection [ Time Frame: at 3, 14, and 28 days after mesenchymal stem cell infusion ]
    Lactate, DIC score, SOFA score, C-reactive protein, and procalcitonin

  6. Ventilator weaning parameters [ Time Frame: at 3, 14, and 28 days after mesenchymal stem cell infusion ]
    Failure of ventilator weaning, weaning time, ventilation time

  7. ICU and hospital stay [ Time Frame: at 28 days after mesenchymal stem cell infusion ]
    Total duration of ICU stay and hospital stay
