2000-09-01 · The proliferative phase of DAD is the stage of organization of the intra-alveolar and interstitial exudate acquired in the acute phase. 19, 36, 52, 55, 59 Type 2 cells begin to proliferate along alveolar septa as early as 3 days following the onset of clinical ARDS, and fibrosis is apparent by the 10th day. 36, 59 This rapid conversion of the lung to a noncompliant, end-stage organ is an important limiting factor for survival in ARDS. 28, 41
Vascular lesions include thrombotic, fibroproliferative, and obliterative changes, which, like the parenchymal lesions, correlate with the temporal phase of diffuse alveolar damage. The pathophysiology of ARDS is complex, and can be divided into an exudative phase, a proliferative phase, and a fibrotic phase. The exudative phase results in a diffuse alveolar damage (Fig. 1), initiated from the initial tissue injury (as per Table 1). Progression of the diffuse alveolar damage in ARDS is divided into three phases.
1. Exudative phase. Duration The respiratory symptoms of ARDS usually start within 6–72 hours after an eliciting risk factor and progress rapidly. The exudative phase usually lasts about 7 days. Pathology Begins 1 to 2 weeks after the initial lung injury.
Proliferative Phase This phase of ARDS usually lasts from day 7 to day 21. Most patients recover rapidly and are liberated from mechanical ventilation during this phase.
It is important to note that DAD can occur in settings other than ARDS and that ARDS can occur with histology other than DAD. Das Acute Respiratory Distress Syndrome (ARDS) ist eine massive Reaktion der Lunge auf diverse schädigende Faktoren und geht mit einer schweren Einschränkung der Oxygenierung einher. Diffuse alveolar damage, abbreviated DAD, is a relatively common lung pathology that is grouped with the diffuse lung diseases and has several clinical correlates.

Accordingly, this could be a first step on to get a more consistent performance than is the (GSK 3β during ARDS via inhibition of alveolar epithelial protein transport. LincRNA-p21, a novel regulator of cell proliferation, apoptosis and DNA

The exudative phase is defined by capillary congestion and intra-alveolar oedema, and is maximum during the first week after the onset of ARDS. The second phase, proliferative, is a phase of repair marked by intense cellular proliferation, especially of alveolar type-2 cells and fibroblasts.
