Neutrophil-to-lymphocyte ratio in predicting prognosis and course of community community-acquired pneumonia in hospitalized patients.
Currently, a marker which could be used both to assess the severity of community acquired pneumonia (CAP) and determine the risk of complications is being searched. According to some authors, Neutrophil-to-Lymphocyte Ratio (NLR) could be such a marker. Therefore, the aim of our research was to determine the diagnostic significance of NLR in patients with CAP and to establish the relationship of NLR with other clinical and laboratory parameters. We conducted a retrospective analysis of 171 case histories of patients with CAP of 3 and 4 clinical groups, with the calculation of NLR (according to the common blood count). In the course of the work, it was found that NLR reflects a balance between the response of neutrophils and lymphocytes and this parameter is associated with the severity of systemic inflammation in patients with CAP. NLR has good diagnostic value in determining the mortality risk in patients with CAP, specially an increase in the level of NLR (more than 10) is associated with a high risk of life-threatening complications
Genetic Testing for Thrombophilia in Case of Unprovoked Episode of Pulmonary Embolism
Venous thromboembolism (pulmonary embolism (PE) and deep vein thrombosis (DVT)) is the third among all cardiovascular syndromes in the world, second only to heart attack and stroke. Estimation of clinical probability of this condition takes into account many factors, including age. But in case of PE probability in young patient data of scales such as Geneva Score (Revised), Wells' criteria for pulmonary embolism, the PERC rule may be misleading. For this group a new influential factor emerges – thrombophilia. The aim of our work was to demonstrate the approach to identifying whom and when to test for genetic predisposition for thrombosis, based on a clinical case of young male with unprovoked episode of PE. Testing patients for thrombophilia is a good way to develop a personalised approach in case of prescribing long-term anticoagulant treatment. Moreover, patient's awareness about congenital condition helps to increase complience which is crucial, due to the fact that in case of unprovoked pulmonary embolism another episode can occur in up to 50 % of cases during the next 5 years. In addition, further accumulation and analysis of data on the amount of genetic risk factors for thrombosis will expand our understanding of this issue and in the future will allow us to better diagnose and treat this condition
Community-aquired Pneumonia on the Background of Coronaviral Disease (COVID-19): Principles of Diagnostics and Determination of Risk Factors of Pathological Process Aggravation
The diagnosis of community-acquired pneumonia (CAP) on the background of COVID-19 is especially actual due to the prevalence of this pathology and the possible aggravation of the pathological process. The aim of our study was to improve the principles of CAP diagnostics on the background of COVID-19 and to determine risk factors for aggravating of the pathological process. Patients with respiratory symptoms who were hospitalized with suspected COVID-19 were examined. General clinical research methods were carried out, determination of SARS-CoV-2 virus RNA by PCR method, computer tomography (CT) to identify the features of lung tissue damage was performed. The main observation group consisted of 37 patients (men – 19 (51.4%), average age – 61 (57; 69) years) with pneumonia on the background of confirmed COVID-19. According to the severity of coronavirus disease, all patients of the main group were divided into 3 subgroups: subgroup 1 included 17 people with moderate COVID-19, subgroup 2 – 13 people with severe COVID-19, subgroup 3 – 7 people with critical COVID- 19 course. The levels of markers of systemic inflammation (C-reactive protein (C-RP) and fibrinogen) were also determined. Since patients with COVID-19 of moderate severity (which is characterized by the presence of community-acquired viral pneumonia) belong to the risk group of severe and critical course, it is suggested to consider the following risk factors for aggravating the pathological process as: temperature over 38.5°C, heart rate over 90 per minute, respiratory rate over 20 per minute, SpO2 ≤ 93%; absolute lymphopenia (less than 0.9 G/L) and an increase in serum levels of C-RP more than 50 mg/L and fibrinogen more than 5 g/L
