[Current view on Blastocystis species: clinical forms, diagnosis and treatment].

The symptomatic form of Blastocystis spp. infection not only with mild diarrhea or dysentery-like syndrome, but also with the development of severe ulcerative necrotic lesions of the intestine. Meanwhile, the pathogenicity of these microorganisms should not be exaggerated, due to majority asymptomatic cases or infection transmission with minor impaired bowel function.

[Epidemiological and clinical aspects of diagnosis, treatment and prophylaxis of imported malaria cases in Russian Federation].

Actually one of the main tasks of health workers in the field of the tropical diseases prevention (malaria) is early detection of malaria imported cases and efficacious treatment. In order to prevent the re-establishment of local malaria transmission by Anopheles mosquitoes from imported malaria cases, and fatal cases of disease there is develop and implement the Case Management Protocol of malaria diagnosis and treatment (2014, 2019) based on long-term experience of epidemiologists and clinicians, taking into account recommendations of WHO (2013, 2015). In this article the main principles of diagnosis and treatment of different malaria species Plasmodium falciparumand Plasmodium vivax-malaria, prophylaxis measures of autochthonous cases from imported cases of the word endemic region are discussed.

[THE CLINICAL AND EPIDEMIOLOGICAL CHARACTERISTICS OF MALARIA CONCURRENT WITH OTHER INFECTIONS AND INVASIONS].

The present review considers malaria infection concurrent with different species of helminths, bacterial and viral infections, as well as mixed malaria pathogens in the subtropical and tropical countries of the world, causing the clinical picture and epidemiological situation to be different. Malaria co-infections with different pathogenic micro-organisms, such as HIV, tuberculosis, viral hepatitides, and others, affect almost one third of the planet's population. It is known that people who are at risk for malaria may be also at risk for other parasitic and infectious diseases, most commonly helminthisms.

[South African tick bite fever in a group of Russian tourists].

The paper describes a clinical case of South African tick bite fever in a group of Russian tourists. The group of 5 people who had been ill with this disease after a tourist trip to the South African Republic (the Kruger National Park in the north-eastern province of Mpumalanga) were followed up. During their trip, all of them were bitten by different insects many times.

[Human babesiasis].

The paper describes a case of imported babesiasis caused by Babesia microti. This is an account of the second case of babesiasis in the Russian-language medical literature. Its clinical picture and laboratory data in the course of the disease are depicted and analyzed.

[Methodological features of DNA isolation for nested PCR for the differential diagnosis of malaria].

Current PCR assays for the differential diagnosis of malaria need to be further developed and certified in the Russian Federation. PCR may serve as a control diagnostic method. These investigations have demonstrated that an erythrocytic clot may be used as an adjunct to microscopy and the described procedure can be employed to isolate DNA for PRC in an inpatient setting.

Peculiarities of a malaria case imported from Myanmar to Moscow (Russian Federation).

An imported case of presumably Chesson strain from Myanmar to Moscow is presented. In the absence of radical treatment with primaquine the patient experienced a series of 5 subsequent relapses after treatment with Delagil (chloroquine). The period between relapses ranged from 47-61 days.

[The specific features of imported Plasmodium vivax malaria, Chesson strain type].

The details of imported case of Chesson strain of P. vivax malaria to Russian Federation (Moscow) from border areas between Myanmar and Thailand is given. It might further confirm the expansion of this strain from its original place in the Western Pacific towards other territories in the World, described in various publications.

[Current course of pneumocystic pneumonia in HIV-infected patients].

Aim: To describe clinical and laboratory characteristics of pneumocystic pneumonia (PP) in patients with HIV-infection for improvement of diagnosis quality.

Material And Methods: Detailed examination was performed in 111 HIV-infected patients with suggested diagnosis of PP. The following investigations were made: clinical, x-ray examinations, total count and biochemical blood tests, enzyme immunoassay, indirect immunofluorescence reaction (II-FR) for Pneumocystis jiroveci antigens in bronchoalveolar lavage fluid (BALF) or induced sputum.

[Role of cytokines in the clinical course of tropical malaria in children].

The paper gives data on impaired cytokine status in children with tropical malaria. There have been heterodirectional changes in the level ofcytokines during the infectious process and in relation to the severity of the pathological process, which allow prediction of the course of tropical malaria. Correlations were found between the clinical and laboratory parameters and the level of proinflammatory cytokines, which provide evidence for an important role of inflammatory mediators in the clinical course of the disease.

[Monitoring delagil (chloroquine) efficacy against imported Plasmodium vivax strains].

The efficiency of P. vivax malaria treatment with delagil (chloroquine) was evaluated in 122 patients, including 82 cases in Moscow and the Moscow region. The origin of the cases was malaria endemic areas in Asia, Africa, the Pacific Region, South America, and Transcaucasia.

[Time course of cytochemical changes in the microbicidal system of neutrophilic granulocytes in children with tropical malaria].

The functional metabolic activity of neutrophilic leukocytes underwent clinical laboratory assessment in tropical malaria. A significant inhibited activity of myeloperoxidase and decreased levels of cationic protein, glycogen, and lipids were revealed while the activities of alkaline and acid phosphatase were increased. The degree of changes in the enzymatic activity of leukocytes and the level of intraleukocytic components depended on both the stage of the disease and the degree of the pathological process and the presence of mixed infections.

[Decline of antibodies to hepatitis C virus during antiviral therapy].

The goal of this study was to investigate interrelationship between changes in anti-hepatitis C virus antibody and response to antiviral therapy. The comparative quantitative analysis of antibodies to individual structural and nonstructural viral proteins was done during two years in three patient groups: initial responders, non-responders and a reference group (without therapy). All patients in the treated groups exhibited decrease in the analyzed antibodies to HCV proteins, but with different patterns.

[Humoral response to hepatitis C virus antigens in coinfection with human immunodeficiency virus type 1].

A humoral immune response to individual hepatitis C virus (HCV) antigens was studied in 49 patients at the subclinical stage of HIV-1 infection. These patients, as compared with a group comprising 50 patients with chronic hepatitis C, showed statistically significant higher levels of HCV-specific immunoglobulins G to nucleocapsid protein and the antigens NS3, NS4ab, NS5a. The group of patients with coinfection did not differ from those with chronic HCV monoinfection in detection rates and anti-HCV IgM.

[Actual problems in diagnosis and treatment of imported malaria].

Analyzing 66 cases of imported malaria, recorded among the patients treated at Moscow Infective Clinical Hospital No. 1 has indicated that despite its typical clinical picture and specific epidemiological history, the prehospital diagnosis of tropical and vivax malaria was correctly made in 20 and 22% of patients, respectively. As few as 3 patients had chemoprophylaxis on an individual basis during their stay in the focus, but they did not comply with the regimen recommended.

[The treatment of patients with imported helminthiases].

The authors treated helminth infestation in 856 patients who have arrived to Russia from tropical countries. Early diagnosis and treatment of helminthiasis in such patients reduce their susceptibility to other diseases in the course of relevant adaptation to new climatic conditions. The authors point to high efficacy of the drugs mebendazol, albendazol, medaminol (against ancylostomiasis, ascariasis, trichocephaliasis), praziquantel (against schistosomiasis and hymenolepiasis).
