[Advantages and limitations of initial combination therapy in pulmonary arterial hypertension patients in Russia].
Pulmonary arterial hypertension (PAH) is severe and often times rapidly progressive disease with fatal outcome. The concept of initial combination of PAH-specific therapies in high risk patients at baseline was first described in the European guidelines on pulmonary hypertension (PH) in 2009, and in low or intermediate risk patients at baseline in 2015. Interestingly, that in Cologne Experts Consensus, and then in the 6th World Symposium on PH medical community started considering initial combination therapy as one of the most important pillars in PAH treatment algorithms in 2018. ⋯ In this narrative review paper we attempted to describe studies on initial dual combination therapy with PAH-specific drugs registered in Russia, i.e. ambrisentan and riociguat, macitentan and riociguat, macitentan and sildenafil in low or intermediate risk patients at baseline, as well as iloprost inhaled and sildenafil, iloprost inhaled and bosentan in high risk patients. Some beneficial pharmacological effects due to the synergy between ambrisentan plus riociguat, and inhaled iloprost plus sildenafil appear to be interesting and require further clinical confirmation. Other initial combinations of PAH-specific agents require large-scale clinical trials as well.

Vitiligo is a common polygenic autoimmune disease in which the foci of depigmentation are formed on the skin and/or mucous membranes as a result of the death of melanocytes. There are several hypotheses for the pathogenesis of the disease, the leading role among them is played the autoimmune hypothesis. This review summarizes the available literature data on the prevalence and structure of comorbid endocrine autoimmune pathology in vitiligo patients. ⋯ In addition, it was shown that the prevalence of endocrine diseases increases with increasing area of depigmentation. The data obtained justify the advisability of conducting a timely examination of vitiligo patients with the aim of early detection of comorbid diseases and the appointment of appropriate treatment. Further studies are needed to investigate the effect of the identified associations on the course of vitiligo and comorbid endocrinopathies, as well as the effectiveness of therapy and the quality of life of patients.

Risk stratification among patients with aortic stenosis remains inadequate, and there is a clinical need for the correct identification of high-risk patients who would benefit from aortic valve intervention before developing left ventricular decompensation. Since the publication of the results of the PARTNER study, transcatheter aortic valve implantation (TAVI) has become the method of choice for aortic valve stenosis in inoperable patients and is a real alternative to conventional surgical replacement of the aortic valve in high-risk patients. ⋯ However, in recent years, the interest of researchers in the use of magnetic resonance imaging in this category of patients has increased. The review article examines the potential role of magnetic resonance imaging in patients with aortic stenosis before and after TAVI.

Hypertrophic cardiomyopathy is the most common inherited heart disorder with high clinical heterogeneity. Every fifth patient is older than 60 years at first diagnosis. This review discusses the possible causes for the late onset of hypertrophic cardiomyopathy, the diagnostic and treatment approaches in the elderly.

The article provides data on modern approaches to the treatment of patients with severe uncontrolled bronchial asthma with an emphasis on the use of dupilumab, a human recombinant monoclonal antibody to the alpha subunit of the interleukin (IL)-4 receptor, which inhibits signal transmission from both IL-4 and IL-13. The results of dupilumab pivotal randomized clinical trials DRI12544, QUEST and VENTURE are summarized. ⋯ Clinical cases with various clinical course of bronchial asthma are described, including cases with frequent exacerbations. In conclusion, dupilumab could be a treatment of choice for the patients with severe bronchial asthma and it is reasonable from an economic, clinical and pathogenetic point of view.
