Clinical characteristics of COVID-19 in patients with tuberculosis and factors associated with the disease severity.

Background: Data on patients with COVID-19 who have pulmonary tuberculosis (TB) are limited. In this study, we compared the clinical characteristics of patients with COVID-19/TB and patients with COVID-19 only. In addition, we analyzed the links between the severity of COVID-19 disease and the clinical characteristics of patients with COVID-19/TB.

The Biological and Clinical Aspects of a Latent Tuberculosis Infection.

Tuberculosis (TB), caused by bacilli from the complex, remains a serious global public health problem, representing one of the main causes of death from infectious diseases. About one quarter of the world's population is infected with and has a latent TB infection (LTBI). According to the World Health Organization (WHO), an LTBI is characterized by a lasting immune response to antigens without any TB symptoms.

Factors associated with culture conversion among adults treated for pulmonary extensively drug-resistant tuberculosis during 2018-2019 in the Russian Federation: an observational cohort study.

Treatment outcomes for Multidrug/Rifampicin-Resistant Tuberculosis (MDR/RR-TB) and Extensively Drug-Resistant Tuberculosis (XDR-TB) remain poor across the globe and in the Russian Federation. Treatment of XDR-TB is challenging for programmes and patients often resulting in low success rates and onward transmission of drug-resistant strains. Analysis of factors affecting culture conversion rate among XDR-TB patients may serve as a basis for optimization of treatment regimens.

Latent tuberculosis infection in children and adolescents in Russia.

Background: After the breakup of the Soviet Union, the annual incidence of tuberculosis (TB) in children 15-17 years of age increased in the Russian Federation from 16 per 100 000 population in 1992 to 37 per 100 000 in 2009, and new control measures were implemented.

Methods: Children were screened annually for TB exposure with a tuberculin skin test (TST) at age 1-8 years. If positive, they were investigated for active TB.

Prediction of unfavorable outcomes in West Nile virus neuroinvasive infection - Result of a multinational ID-IRI study.

Background: WNV causes 1.4% of all central nervous system infections and is the most common cause of epidemic neuro-invasive disease in humans.

Objectives: Our main objective was to investigate retrospectively West Nile virus neuroinvasive disease (WNND) cases hospitalized during 2010-2017 and identified factors that can influence prognosis.

Recent autochthonous cases of leishmaniasis in residents of the Republic of Dagestan, Russian Federation.

Eighty years after the last published record of human leishmaniasis from Dagestan, Russian Federation, we report two recent cases which were most probably acquired locally: one case of visceral leishmaniasis in a 2-year old child, and one cutaneous leishmaniasis case in a 39-year-old man co-infected with HIV, both resident in Dagestan.

Epidemiological and etiological features of travel-related febrile illnesses in hospitalized Russian children and adults: A single-centre, retrospective analysis in Moscow.

Background: A number of factors can lead to differences in infectious disease morbidity in children versus adults after a trip abroad. We aimed to investigate the epidemiological and etiological features of infectious diseases in children after international travel.

Methods: we analyzed the medical records of 2135 patients (416 children) who were hospitalized during the period 2009-2017 after return from international travel.
