Review Case ReportsSevere Legionella pneumophila pneumonia and non-invasive ventilation: presentation of two cases and brief review of the literature.
Legionella pneumophila is an agent also well known to be frequently responsible for severe community acquired pneumonia. Recent studies regarding severe community-acquired pneumonia have shown that Legionella pneumophila is the second most common cause of admission to ICU, not far behind pneumococcal pneumonia. The mortality of severe Legionella pneumonia is high (30%). ⋯ The use of non-invasive ventilation in severe community acquired pneumonia is controversial. However, after recent pandemics, the number of studies reporting good rates of success for NIV has increased. Both our patients were managed in a respiratory intermediate care unit, avoiding invasive ventilation and invasive monitoring, which lowered costs yet was equally effective in providing a good outcome when compared to intubation in the Intensive Care Unit.

Review[Genetic variants of alpha-1 antitrypsin: classification and clinical implications].
Inherited alpha-1 antitrypsin deficiency is listed among the three most common genetic disorders in Caucasians. It considerably increases the risk of progressive obstructive lung diseases, mostly chronic obstructive pulmonary disease, as well as chronic liver disorders, hepatitis, cirrhosis, and cancer. It is estimated that more than 5.5% of the Polish population carries one of the most common deficiency phenotypes, which might be relatively easily detected due to low alpha-1 antitrypsin serum concentration. ⋯ These dysfunctional alpha-1 antitrypsin variants are characterized by scarce antiproteolytic activity and quite often by fully effective protein production resulting in normal serum levels. Consequently, dysfunctional variant identification is possible only by means of pheno- or genotyping. This review presents clinically useful characteristics of main genetic alpha-1 antitrypsin variants.

Review[Non-invasive ventilation in treatment of adults with chronic respiratory failure].
Non-invasive mechanical ventilation (NIV) is a modern method of chronic respiratory failure (CRF) treatment. With the development of medicine and society known as "western", the number of elderly people, in whom there is overlapping of chronic diseases such as COPD, is growing. In adult population NIV is used in the treatment of neuromuscular diseases such as amyotrophic lateral sclerosis (ALS) or spinal muscular atrophy. ⋯ The aim of this review is to disseminate knowledge on the potential role of NIV in adults with CRF. This paper attempts to analyze the available knowledge concerning NIV in adults with CRF. Special attention is paid to the potential pathomechanisms which should become the subject of future research.

Observational StudyEvaluation of COPD progression based on spirometry and exercise capacity.
Chronic obstructive pulmonary disease (COPD) is characterized by an airflow limitation that is usually progressive. The progression of COPD expressed as the rate of an annual decline in FEV 1 is very heterogeneous. Exercise capacity in COPD patients is often diminished and becomes worsened over the time. The purpose of the study was to examine how the change in FEV 1 and exercise capacity would deteriorate over long-term observation. ⋯ We observed over time deterioration in exercise capacity in COPD patients which is independent of decline in airflow limitation. The long term follow-up of exercise capacity is important in monitoring of COPD patients in addition to pulmonary function.
