The HIV cascade model can be used as an epidemiological surveillance tool and for assessing the quality of medical care for HIV-positive people. It is possible to use the model for the entire population of people living with HIV, in various socio-demographic groups, by region, years and other indicators. This article describes the features of a HIV cascade model depending on the goals for its use.

Review Meta Analysis
[Umifenovir and coronavirus infections: a review of research results and clinical practice].
Coronaviruses are known to cause acute respiratory infections. Antiviral therapy, including for COVID-19, is based on clinical practice, experimental data and trial results. The purpose of this review is to: provide and systematize actual preclinical data, clinical trials results and clinical practice for antiviral agent umifenovir (Arbidol). ⋯ Therapy with umifenovir, led to an increase percentage of patients with negative results of PCR tests on days 714 (I2=69.8%, RR 0.48, 95% CI 0.190.76; p=0.001). The efficacy and safety of antivirals against SARS-CoV-2 still requires clinical investigation. Moderate forms of COVID-19 could be effectively treated by antivirals, but severe forms of COVID-19, characterized by pulmonary immunopathology, require different approaches to treatment.

Clinical characteristics of disseminated intravascular coagulation (DIC) in COVID-19 infection and assessment of the effectiveness of complex therapy for this syndrome at the stages of prevention and treatment of various complications. ⋯ DIC syndrome with the development of thrombovasculitis is the most important pathogenetic mechanism for the development of microthrombotic and hemorrhagic disorders in organs during infection with COVID-19, leading to dysfunction of the lungs, brain and other nerve tissues, kidneys, thromboembolic complications, etc. Many symptoms of the disease may be associated with a violation of the nervous regulation of the functions of organs and systems. Prevention of thrombovasculitis is effective already at the stage of the first manifestation of the disease with the outpatient use of direct anticoagulants (oral, low molecular weight heparins). In case of more severe manifestations (complications) of the disease, additional use of freshly frozen plasma and plasmapheresis is effective.

Review Classical Article
[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.
