Thus, we assessed if multidrug-resistant tuberculosis treatment practices from 2012-2018 in Uzbekistan were compliant with national guidelines in terms of regimens prescribed, weight-based drug dosages used, and documentation of treatment changes (such as prolongation of intensive phase, change of drugs, and their reasons) in the treatment card and Consilium form. A total of 1481 patients were included.

Effectiveness and safety of fully oral modified shorter treatment regimen for multidrug-resistant tuberculosis in Georgia, 2019-2020.

Tuberculosis treatment is challenging, especially among people with drug-resistant forms of tuberculosis. The introduction of fully oral modified short treatment regimen has a great potential to shorten duration of treatment, improve safety and ultimately increase treatment success rate. In 2019 Georgia has piloted the modified fully oral shorter treatment regimen in a routine programmatic condition.

Incidence rate and time to serious adverse events among rifampicin resistant tuberculosis patients in Georgia treated with new and repurposed anti-tuberculosis drugs, 2016-2018.

Considering the complexity of second-line anti-tuberculosis (TB) treatment regimens, the management of drug-resistant TB (DR-TB) in Georgia remains a major challenge. Since the introduction of new and repurposed anti-TB medications, the implementation of active TB Drug Safety Monitoring (aDSM) was a critical program component to help establish safety and manage all treatment related Serious Adverse Events (SAEs). In our study, we aimed to describe the occurrence, characteristics and timing of SAE among patients with Rifampicin Resistant and Multi-Drug Resistant TB (RR/MDR-TB) receiving new and/or repurposed anti-TB medications (bedaquiline, delamanid, linezolid, clofazimine, imipenem) during the period of 2016-2018 in Georgia and identify predictors of SAE.

The reporting of the mode of transmission among HIV-positive men who have sex with men in Lviv oblast, Ukraine, 2014-2018.

Introduction: Men who have sex with men (MSM) are one of the key populations driving HIV/AIDS epidemic globally. To date, MSM is the only population in Ukraine where the prevalence and incidence of HIV is increasing. As HIV-positive MSM might feel uncomfortable to report homosexual intercourses as a possible mode of transmission (MoT) of HIV, they prefer being registered as patients with heterosexual or non-defined MoT.

When will the coughing stop? Characteristics of children with pertussis (whooping cough) in Armenia (2014-2018).

Introduction: Despite the reported cases of whooping cough in Armenia, there has been no formal evaluation of "who these cases are and their load on hospital wards". In a tertiary reference hospital, we determined the trend in hospitalized pertussis cases stratified by vaccination status and risk factors associated with apnea and hospital stay.

Methodology: Retrospective cohort study of children (< 18 years) with confirmed pertussis hospitalized at the Republican Infectious Diseases Hospital between 2014 and 2018.

Free hospitalization for acute respiratory infections in children: what effect and how much does it cost for Armenia?

Introduction: The "Child Certificate" program, launched in Armenia in 2011, made hospitalization for children less than seven years free in order to improve access to hospitalization, reduce out-of-pocket expenses and ensure Universal Health Coverage. We aimed to estimate trends in the number of outpatient and hospitalized acute respiratory infection (ARI) cases and related under-five mortality.

Methodology: Cross-sectional study using data from national databases before (2008-2011) and after (2012-2017) Program implementation.

Mind the gap: Improving the performance of the reference laboratory to end-tuberculosis in Armenia.

Introduction: A one of the step towards achieving TB related targets is to ensure early and quality diagnosis of TB in national laboratories. WHO recommends that all national reference laboratories in TB burden countries strive to reach accreditation by 2025, based on ISO15189:2012 quality management system standard. To identify gaps, progress and evaluated the evolution in implementation QMS we performed a formal assessment of the national TB reference laboratory of Armenia, as well as estimates the specific quality indicators of NRL activity.

Shifting from an inpatient to outpatient centered model through transforming the TB financing in ex-Soviet countries.

Introduction: In former Soviet Union countries, tuberculosis (TB) financing largely relies on a hospital-centered model. The World Health Organization favors transformation to ambulatory treatment since it is cheaper and patient-centered. We explored policy and decision maker's perspectives on: a) enabling factors for transformation in Armenia and b) challenges and ways forward in doing so in Ukraine and Tajikistan.

People with high HIV viral load within risk networks: who are these people and who refers them best?

Introduction: Viral load is one of the most important determinants for HIV transmission. Identification of people with high viral load (PHVL) can be effective in limiting onward HIV transmission. In order to improve the identification of these individuals within risk networks, we determined a) the number of PHVL recruited through risk networks b) their socio-demographic, behavioural and clinical characteristics and c) the characteristics of individuals who referred these PHVL to the study.
