Aim. To study the causes of falciparum malaria deaths in Russian Federation and to optimize therapy for severe forms of the disease. Materials and methods. The analysis of falciparum malaria cases with deaths recorded in Russian Federation from 2013 to 2017 was conducted. The results of optimization of pathogenetic therapy of severe forms of falciparum malaria for the prevention of adverse outcomes in the intensive care unit of the Infectious Clinical Hospital №2 of Moscow in 44 patients with severe course are presented. Treatment, clinical laboratory and instrumental investigations were carried out in accordance with our intensive care protocol, which took into account the current WHO recommendations. Results. From 2013 to 2017 there were nine deaths from falciparum malaria reported in patients from African countries (6) and India (3). In Russia, due to the lack of effective drugs of artemisinin group, quinine with tetracycline or doxycycline is used for etiotropic therapy of patients with complicated form of falciparum malaria. In the management of such patients, the basis for treatment was the prevention of ischemic, reperfusion injuries of organs and hemorrhagic complications. In the infectious clinical hospital №2 of Moscow, since 2007, the intensive care unit has developed and tested a protocol for intensive therapy in patients with severe and complicated forms of falciparum malaria, including preventive methods of extracorporeal hemocorrection with prolonged veno-venous hemodiafiltration therapy and plasmapheresis, as a result of which the mortality rate decreased from 84 to 6.8% Conclusion. The country's lack of anti-malarial drugs, the insufficient awareness of the population about the risk of infection and measures to prevent malaria, late referral of cases for medical care and errors of clinical diagnosis and treatment annually lead to fatal outcomes. In such situation, the experience of optimizing the treatment of severe falciparum malaria is particularly useful, allowing decreasing the mortality.

The aim of the study was to analyze the incidence and prevalence of opportunistic diseases and comorbidities in patients admitted in the intensive care unit. Materials and methods. A specialized intensive care unit (ICU) for patients with severe HIV infection was set up in 2014 at the infectious diseases 2nd state hospital Moscow. It provides intensive care and treatments for HIV patients with severe co-morbidities and opportunistic infections. Retrospective analysis of medical records from 2014-2016 was carried out. Also carried out was a comparative study of the most common presentation of secondary diseases with available data of HIV patients in Russia from 1993-1997. Results. The number of patients treated increased from 455 to 852, and the death rate in the department decreased from 64.8 to 50.2% since it began operating. The opportunistic infections noted were cytomegalovirus, pneumocystis pneumonia, esophageal candidiasis, tuberculosis and toxoplasmosis of the brain. The most common comorbidities were chronic hepatitis C and mixed form of chronic hepatitis with cirrhosis complications. Despite the vast diagnostic possibilities, bacterial pneumonia and encephalitis of unknown origin significantly occurred. Comparative study of secondary disease since the early 1990s revealed a significant increase in cerebral toxoplasmosis (from 1.7 to 10.4%), pneumocystis pneumonia (from 5.2 to 16.0%) and encephalitis of unspecified etiology (from 13.8 to 39.4%) Conclusion. Disease severity among HIV patients is increasing. CMV and pneumocystis pneumonia were predominant opportunistic diseases. There were significant changes in the presentation of secondary diseases compared to data from 1993-1997.

The systemic inflammatory response plays a key role in the development of atherosclerosis, insulin resistance (IR) and diabetes mellitus 2-type (diabetes mellitus). IR in patients with chronic hepatitis C (CHC) is considered as a possible factor in the progression of fibrosis, a predictor of the development of DM T2 and a component of the metabolic syndrome. The use of biomarkers of non-specific inflammation can be a valuable tool for assessing the risks of IR and cardiovascular diseases in patients with chronic hepatitis C. Aim of the study. To determine the role of nonspecific inflammation in the formation of IR and metabolic syndrome in patients with chronic hepatitis C. Materials and methods. The study included 205 patients with CHC aged 18 to 69 years. Patients with CHC are randomized into two groups depending on the presence of IR: group 1 - patients with a HOMA index ≥2.77, which corresponded to IR (n=110); group 2 (n=95). The levels of serum iron, C-reactive protein (CRP), serum ferritin and adipose tissue hormones [leptin, resistin, adiponectin and tumor necrosis factor-α (TNF-α)] were additionally investigated. Results. At all stages of development of IR, nonspecific inflammation was detected (according to ferritin, CRP and serum iron), increasing with increasing HOMA index [Homeostasis Model of Assessment - Insulin Resistance (HOMA-IR)] (Matthews D., 1985), metabolic syndrome and its components. In the analysis of indicators in patients with chronic hepatitis C with a body mass index <25 kg/m2, conjugacy of IR with low-intensity inflammation, high viral load and hypersecretion of TNF-α was detected. Conclusion. Given the high predictor role of CRP indicators in predicting IR, it should be used as a surrogate screening marker of IR in patients with chronic hepatitis C and should be actively treated for violations.

The aim of the study. To evaluate of parameters of lipid peroxidation - antioxidant defense changes in women of fertile age with chronic viral hepatitis (CVH) and with HIV (human immunodeficiency virus) infection, depending on the degree of inflammatory process activity in the liver. Materials and methods. 99 women of reproductive age were examined, of them 44 patients with chronic parenteral viral hepatitis, 27 patients with HIV co-infection (HIV + hepatitis B and/or C) and 28 practically healthy women (control group). Results. Patients with CVH in combination with HIV-infection with the presence of minimal and low degree of inflammatory activity in comparison with patients with CVH-monoinfection had a higher content of lipid peroxidation products (an increase in the content of diene conjugates and ketodienes and conjugated trienes), reduced values of total antioxidant activity, superoxide dismutase activity, as well as the concentration of fat-soluble vitamins α-tocopherol and retinol. In the group with CVH and HIV with moderate and high degree of activity, similar, but even more pronounced changes in the system of lipid peroxidation were observed. Conclusion. The presence of co-infection - CVH in combination with HIV infection with minimal and low, as well as moderate and high inflammatory activity, is characterized by more intensive lipid peroxidation processes and a pronounced lack of antioxidant factors than with CVH-monoinfection.

The aim of the study was to evaluate the clinical and interferon-modulating efficacy of a combination of rectal and topical dosage forms of IFN-α2b with antioxidants in the treatment of acute respiratory infections (ARIs) in comparison with other variants of antiviral therapy. Materials and methods. A total of 90 servicemen aged 19.2±0.9 years with uncomplicated forms of ARI were hospitalized not later than 48 hours after the onset of the disease. Patients were randomized into 3 groups of 30 people each. In the first group, patients received rectal suppositories containing IFN-α2b (1 million IU) and antioxidants (alpha-tocopherol acetate and ascorbic acid) twice a day for 5 days. In the second group, patients received intranasally a gel formulation containing IFN-α2b (36 000 IU/1 g) and antioxidants 3 times a day in addition to the above suppositories. In the third group, patients were prescribed umifenovir (reference drug) at dose of 200 mg 4 times a day for 5 days. The dynamics of regression of clinical manifestations of ARI in different groups, changes in concentrations of IFN-α and IFN-γ in blood plasma, as well as spontaneous and induced production of these cytokines by blood cells ex vivo were evaluated. After that, the patients were observed for another 3 months to register repeated cases of hospitalization for ARI. Results. Marked tendency to accelerate the regression of symptoms of intoxication and fever was observed when intranasal dosage form of IFN-α2b was administered to patients receiving the rectal form of this cytokine. The combination of rectal and topical dosage forms of IFN-α2b with antioxidants was more effective than monotherapy with the rectal suppositories in preventing repeated hospitalization for ARI. The above combination caused the most complete correction of induced production of IFN-α by blood cells ex vivo at its initial deviation from the norm. Conclusion. The obtained data indicate the expediency of using the combination of rectal and topical dosage forms of IFN-α2b with antioxidants for treatment of ARI.

Patent foramen ovale and hereditary thrombophilia are both known risk factors for ischemic stroke. Artery of Percheron is a rare anatomical variant in which vast areas of the midbrain and thalamus have a single source of blood supply. This case report presents a 45-years old female patient with bilateral thalamic stroke due to Percheron artery occlusion, with a combination of hereditary thrombophilia and patent foramen ovale as the risk factors. Modern approaches to the diagnosis and secondary prevention of this pathology are also discussed herein.

In the article we present three clinical observations demonstrating that HCV infection in patients with remission of Wilson disease causes an recrudescence of the disease, in one of the observations - decompensation of liver cirrhosis. In this study we first describe on the successful treatment of HCV infection with direct antiviral drugs in patients with Wilson disease. Establishment of all factors of liver damage and successful treatment (elimination of the virus, adequate lifelong medical treatment) allow to expect a favorable prognosis in patients with a combination of Wilson disease and HCV infection.

The article describes the clinical observation with an unfavorable outcome of the generalized form of salmonella infection caused by Salmonella typhimurium group B in a woman of 60 years without immunodeficiency, complicated by the development of multiple abscesses of the lower parts of abdominal cavity, probably of appendicular origin. In a short literary review, the pathogenetic mechanisms that contribute to the formation of generalized and extraintestinal forms of salmonella infection are discussed.

Injections of botulinum toxin are widely used in different medical fields, namely neurology, urology, stomatology, cosmetology, gastroenterology etc. Preparations of botulinum toxin type A (BTA) prevent the release of acetylcholine at the endings of motor nerves leading to the long-term muscle relaxation. It has been acknowledged that treatment with BTA has very good safety profile and tolerability. Extremely rare but severe complication of botulinotherapy (BT) is a condition, which is associated with generalized muscle Weakness, swallowing difficulty, respiratory arrest, and may lead to the lethal outcomes in the solitary cases. Such disorders, which present like botulism, are known as botulism-like syndrome and iatrogenic botulism. We report a clinical case of such complication in the paper. The probability of the development of such rare but severe complications necessitates certain awareness and vigilance among clinicians performing BT.

In the modern clinic of internal diseases, the specific gravity of the infectious pathology, manifested by various clinical syndromes, is increasing. Infectious pathology is represented by diseases of the respiratory system, heart disease (infective endocarditis, cardioimplant infections, viral myocarditis), infectious arthropathies, extrahepatic manifestations of viral hepatitis, cytopenic syndromes, various manifestations of sepsis and some other conditions.In most cases, the diagnosis and management of such patients is the responsibility of the internist, who must be able to suspect the infection and carry out its verification. In the process of diagnostic search and management of patients, close interaction of the internist with a clinical microbiologist, clinical pharmacologist and other related specialists is necessary.
