Modern methods of diagnosis and treatment of pulmonary hemorrhage

The term “chronic critical illness” (CCI) refers to patients with prolonged dependence on intensive care. In most patients, CCI is triggered by severe brain injury. Ever more studies researching the microbiota in pathologic conditions are published every year, but a lot is yet to be elucidated about the composition of the gut microbiota in CCI. The aim of this study was to investigate possible correlations between changes in the taxonomic abundance of the gut microbiota, levels of proinflammatory and neurological serum biomarkers and the severity of central nervous system injury in patients with CCI. Our prospective observational pilot study included 29 patients with CCI. Using real-time PCR allowed us to detected changes in the taxonomic abundance of the gut microbiota. The correlation analysis of serum biomarkers and the taxonomic composition of the gut microbiota revealed statistically significant correlations between cortisol levels and the abundance of F. prausnitzii (r = ‒0.62; p < 0.05) and B. thetaiotaomicron (r = ‒0.57; p < 0.05) in vegetative state patients; between the CRP/albumin ratio and the abundance of S. aureus (r = 0.72; p < 0.05); between the abundance of B. fragilis group/F. prausnitzii and S100 levels (r = 0.45; p <0.05) in conscious patients; between Glasgow coma scale scores and the abundance of Enterococcus spp. (r = ‒0.77; p <0.05) in both groups. Thus, the association between the changes in the taxonomic composition of the gut microbiota and the severity of neurologic deficit can be evaluated using PCR-based diagnostic techniques and blood serum biomarkers. This approach will help to optimize antibacterial treatment regimens and/or develop alternative strategies to minimize the aggressive effect of antibiotics on the gut microbiota.

Aim. The study aimed at investigating the relationship between severe exacerbations of chronic obstructive pulmonary disease and hemorrhagic component of endobronchial inflammation. Materials and methods. Clinico-endoscopic characteristics of 118 patients presenting with severe infectious exacerbation of chronic obstructive pulmonary disease, bloody expectorations and endoscopically confirmed hemorrhagic component of endobronchial inflammation have been analyzed. All patients underwent a series (5-6) of bronchoscopic examinations accompanied by collection of bronchoalveolar lavage specimens to reveal the presence of acid-resistant mycobacteria and to determine the bacterial flora. The exclusion criteria were the concomitant pulmonary or extrapulmonary pathologic conditions which could lead to hemorrhagic endobronchial manifestations. The other direction of the study was to investigate a correlation between jugulation of the exacerbation and dynamics of such endobronchial symptoms as mucosal edema and hyperemia, quality of bronchial secretions and hemorrhagic component of endobronchial inflammation. Results. All patients were found to have diffuse endobronchitis of severity grade II (39.83%) or III (60.17%) by Lemoine. The neoplastic and tuberculosis genesis of the hemorrhagic component of endobronchial inflammation and its clinical equivalent, the bloody expectorations, had been ruled out. In 50.85% of cases the hemorrhagic component of endobronchial inflammation could not be accounted for by hemolytic properties of cultured microorganisms. The mucosal edema and hyperemia remained stable during jugulation of the exacerbation. Unlike the improvement of quality of bronchial secretions, faster reversal of the hemorrhagic component of endobronchial inflammation showed statistical significance. Conclusion. The hemorrhagic component of endobronchial inflammation can represent a non-obligatory manifestation of severe exacerbation of chronic obstructive pulmonary disease, and its relief is the earliest endobronchial sign of incipient remission from severe COPD exacerbation.
