Aim. To investigate the relationship between changes in indicators of arterial stiffness of various types of vessels, hemodynamic pulsatility, renal function and renal blood flow in patients with coronary artery disease (CAD) and arterial hypertension in the presence or absence of type 2 diabetes mellitus (T2DM). Materials and Methods. The study included 96 patients with CAD and arterial hypertension; among them, 54 subjects had T2DM and 42 did not. Сarbohydrate and lipid metabolism, renal function, stiffness of various types of arteries, parameters of hemodynamic pulsatility and renal blood flow were investigated. Results. Arterial stiffness of various types of vessels was increased in the T2DM group: carotid?femoral pulse wave velocity as a marker of aortic stiffness (a vessel of the elastic type) was increased by 16% (p
In recent tuberculosis years is the main cause of morbidity and death among patients with HIV infection. Modern diagnostics of tuberculosis includes mass screening of the population: digital fluorography from the age of 15 and immunodiagnostics in children and adolescents. Detection of mycobacterium tuberculosis by microscopy occurs in forms of tuberculosis with the decay of lung tissue. Such patients represent a high epidemic risk. To improve the verification of diagnosis in the practice of a phthisiologist, molecular genetic methods for the search for mycobacteria are increasingly used, based on the identification of specific fragments of the DNA chain in the diagnostic material. The most widely used method is the polymerase chain reaction (PCR), which is based on directed DNA amplification. The latest innovation is fully automated systems using cartridge technology GeneXpert. The advantages of GeneXpert are high sensitivity, speed (result in 2 hours), real-time PCR detection, exclusion of sample contamination. The technique of cartridge technology is constantly being improved, various cartridges are used on its platform, which not only detect M. tuberculosis, but also determine the sensitivity to anti-tuberculosis drugs - rifampicin (MTB / RIF cartridge) or several anti-TB drugs (MTB / XDR). Cartridges have been developed that are able to detect Mycobacterium tuberculosis (MBT) at an even lower concentration in the test material - MTB / RIF (Ultra). GeneXpert technology can be used to diagnose extrapulmonary tuberculosis by examining various biological materials, which are more effective in detecting tuberculosis in children and adolescents, in HIV-positive individuals.
Background & Aims. This paper presents the results of the observational study of ibrutinib in patients with chronic lymphocytic leukemia (CLL), conducted in SP Botkin Municipal Clinical Hospital. The main objective was the analysis of complications of ibrutinib and identification of factors, influencing the dosage regimen; the secondary objective was the estimation of the total response to treatment, event-free and overall survival. Materials & Methods. The study included 96 patients with CLL with indications for ibrutinib therapy. The median age was 64,9 years (range 32-91 years), the study population consisted of 69 (72 %) men and 27 (28 %) women. The condition of 25 (26 %) patients according to the ECOG scale was of > 3 points. The disease of stage C were diagnosed in 36 (37 %) patients. Deletion of 17p/TP53 mutations were detected in 29 (33 %) of 87 patients. Seventy patients had refractory CLL. The median of the number of the lines of the previous therapy was 3 (range 1-9). Adverse events were assessed in accordance with the CTCAE criteria, version 4.0; the bleeding severity was evaluated using ITP-specific bleeding score; hematological complications were classified according to the recommendations of IWCLL-2008. Results. Ibrutinib was administered at a dosage of 420 mg per day daily until progression or intolerable toxicity. The median duration of ibrutinib therapy was 10.3 months. brutinib was shown to have moderate toxicity, mostly of grade I or II. The bleeding was the most frequent complication. Of the hematological complications, thrombocytopenia was the most common (35 %); neutropenia < 1 <sup>x</sup> 10<sup>9</sup>/L was observed in 4 patients. GIT complications were identified in 51 (53 %) patients. Atrial fibrillation was registered in 5 patients, who initially had sinus rhythm. The total of 144 infections were diagnosed in 64 (66 %) patients. Severe infections (> grade III) developed in 26 % of patients. The treatment response was assessed in 92 patients. The overall response to treatment was 89 %. Complete remission, partial remission and partial remission with lymphocytosis were achieved in 4 (4 %), 57 (62 %), and 21 (23 %) patients, respectively. The event-free survival and overall survival by the month 10 was 90 % and 91 %, respectively. For this observation period, ECOG status and the number of the lines of therapy prior to ibrutinib had the prognostic value. Conclusion. Ibrutinib was shown to have high efficiency in relapsed/refractory forms of CLL. The nature of the ibrutinib toxicity is fundamentally different from that of the conventional chemotherapy. The frequency of ibrutinib therapy complications and patients' non-compliance depends on the intensity of the previous treatment of CLL. Despite a short observation period, it can be concluded that ibrutinib had the greatest impact on the patient's quality of life when administered for the first relapse. The low toxicity of ibrutinib is likely to allow the combination with other antitumor agents.
Pulmonary tuberculosis has a lot of clinical manifestations, and it complicates the diagnosis of tuberculosis in the general clinical practice. We studied the clinical manifestations of tuberculosis detected in the pulmonary department and compared them with the significancy of diagnostic methods.Material and methods. People with a verified diagnosis of lung tuberculosis (n = 109) were examined using the GeneXpert MTB/RIF method if Ziehl Nielsen bacterioscopy has negative results or if there was no effect of treatment for two weeks.Results. All patients had complaints of both intoxication and bronchitis as with pneumonia on admission. Infiltrative tuberculosis (57.1 %; n = 68), disseminated tuberculosis (16.8 %; n = 20) were most often diagnosed. We looked for correlations between dyspnea and the prevalence of the process (p = 0.24), dyspnea with temperature (p = 0.24), the presence of pain in the chest (p = 0.405), the results of immunodiagnostics and sputum examination (p = 0.133). We found out that there are no such correlations in tuberculosis. The term for diagnosing tuberculosis was 7.97 ± 3.9 days in the presence of cough with sputum and 9.04 ± 4.3 days in the case of dry cough. The term for diagnosing tuberculosis was 12.31 ± 4.9 days in patients without cough. Mycobacterium tuberculosis was detected using GeneXpert MTB/RIF molecular genetic methods with nonproductive cough in 84.5 % (60 people out of 71), while in the first days of hospitalization in 46.6 % of patients (28 people out of 60, p < 0.001).Conclusion. It was found that the period of hospitalization is little related to the characteristics of patients and depends on organizational measures to identify mycobacterium tuberculosis. It is recommended to immediately apply the GeneXpert MTB/RIF method to patients with mild tuberculosis.
