Prevalence of inappropriate tuberculosis treatment regimens: a systematic review

A potential threat to the success of new tuberculosis (TB) drugs is the development of resistance. Using drugs in appropriate regimens, such as those recommended in the World Health Organization (WHO) treatment guidelines, prevents the development of resistance. We performed a systematic review to assess the prevalence of inappropriate prescription of TB drugs for the treatment of TB

Migration, TB control and elimination: Whom to screen and treat

Tuberculosis (TB) in migrants represents an important clinical and public health threat, particularly in low TB incidence countries. The current review is aimed to assess issues related to screening and treatment of migrants with latent TB infection or TB disease. Keywords: TB migrants, TB elimination, TB control screenin

Childhood tuberculosis: progress requires an advocacy strategy now

Childhood tuberculosis (TB) is a preventable and curable infectious disease that remains overlooked by public health authorities, health policy makers and TB control programmes. Childhood TB contributes significantly to the burden of disease and represents the failure to control transmission in the community. Furthermore, the pool of infected children constitutes a reservoir of infection for the future burden of TB. It is time to prioritise childhood TB, advocate for addressing the challenges and grasp the opportunities in its prevention and control. Herein, we propose a scientifically informed advocacy agenda developed at the International Childhood TB meeting held in Stockholm, Sweden, from March 17 to 18, 2011, which calls for a renewed effort to improve the situation for children affected by Mycobacterium tuberculosis exposure, infection or disease. The challenges and needs in childhood TB are universal and apply to all settings and must be addressed more effectively by all stakeholders

Randomized Trials to Optimize Treatment of Multidrug-Resistant Tuberculosis: The time for action is now

The time is now right for randomized trials of MDR-TB, say the authors, as the expansion of MDR-TB programs provides the setting in which trials can be implemented

Application of the hollow fibre infection model (HFIM) in antimicrobial development: a systematic review and recommendations of reporting

Item does not contain fulltextOBJECTIVES: This systematic review focuses on the use of the in vitro hollow fibre infection model (HFIM) for microbial culture. We summarize the direction of the field to date and propose best-practice principles for reporting of the applications. METHODS: Searches in six databases (MEDLINE®, EMBASE®, PubMed®, BIOSIS®, SCOPUS® and Cochrane®) up to January 2020 identified 129 studies meeting our inclusion criteria. Two reviewers independently assessed and extracted data from each publication. The quality of reporting of microbiological and technical parameters was analysed. RESULTS: Forty-seven out of 129 (36.4%) studies did not report the minimum pharmacokinetic parameters required in order to replicate the pharmacokinetic profile of HFIM experiments. Fifty-three out of 129 (41.1%) publications did not report the medium used in the HFIM. The overwhelming majority of publications did not perform any technical repeats [107/129 (82.9%)] or biological repeats [97/129 (75.2%)]. CONCLUSIONS: This review demonstrates that most publications provide insufficient data to allow for results to be evaluated, thus impairing the reproducibility of HFIM experiments. Therefore, there is a clear need for the development of laboratory standardization and improved reporting of HFIM experiments

Effectiveness of tuberculosis contact tracing among migrants and the foreign-born population

A literature review was performed to assess the effectiveness of tuberculosis (TB) contact tracing among migrants and the foreign-born population with emphasis on the European Union. Effectiveness of contact tracing was assessed using the following indicators: coverage, proportion of contacts with TB (TB yield), proportion of contacts with latent tuberculosis infection (LTBI yield) and number of investigated contacts per index case (contacts/index case ratio). The key findings from the literature review were: Among foreign-born contacts, a higher median LTBI yield was found compared with contacts born in the country, when exposed to the same foreign-born index cases. No clear differences were observed between TB and LTBI yield among contacts of foreign-born index cases compared with contacts of index cases from the general population (including the foreign-born) due to the large variation seen between the studies. The included non-European studies screened more contacts per foreign-born index case, used lower cut-off values to define a positive tuberculosis skin test and found higher LTBI yields among contacts. Although the high heterogeneity across the studies made the comparison challenging, several conclusions are made regarding contact tracing among migrant

Migrant tuberculosis screening in the EU/EEA: yield, coverage and limitations

A systematic literature review was performed with the objective of assessing the effectiveness of tuberculosis (TB) screening methods and strategies in migrants in European Union/European Economic Area (including Switzerland) countries. Extracted data on yield and coverage were used as indicators of effectiveness. Reported yields varied considerably between studies and countries. Considering only the 14 studies representative of national screening programmes, a median yield of TB disease of 0.18% (interquartile range 0.10-0.35%) was reported. The data did not indicate differences in effectiveness between the three main strategies: 1) screening at port of entry; 2) screening just after arrival in reception/holding centres; and 3) screening in the community following arrival in European Union countries. The variation seen probably reflects variation in risk factors for TB, in particular the composition of the migrants entering the country. Recommendations include the need for improved data for guiding the optimal frequency and duration of screening; assessment and improvement of cost-effectiveness; access to healthcare for migrants, including illegal migrants; ensuring a continuum of care for those screened; and consideration of screening for latent TB infection with caution. Finally, screening should be a component of a wider approach, rather than a stand-alone interventio
