Regularities of changes in laboratory parameters in patients with A/H1N1 influenza pneumonia
The medical records of 97 patients with A/H1N1 influenza pneumonia were analyzed. The important feature of the disease is a high risk of fatal outcomes, the direct cause of which is acute respiratory distress syndrome (ARDS). The most significant abnormalities of laboratory values were noted in this category of patients. In ARDS, leukopenia or normocytosis changed to leukocytosis, which is attributed to massive bacterial infection. These patients were also recorded to have immunodeficiency-induced lymphopenia and disseminated intravascular coagulation-induced thrombocytopenia. The marked elevation of transaminases mainly due to asparagine transaminase and the increase of creatine phosphokinase suggest that the most severe category of patients has rhabdomyolysis. Characteristic of this was a reactive rise of amylase. In ARDS, diminished renal functional capacity reflected the higher blood levels of creatinine and urea.
