The TBNET academy provides an excellent forum for 20 young European clinicians and researchers in the field of tuberculosis to exchange ideas and to learn from each other under expert guidance and mentorship. It is a very good opportunity for upcoming researchers to participate in a pan-European research network, to get to know colleagues in the same field from different parts of Europe and to plan future collaborations.
 
Everyone who will take part in the TBNET Academy will have an active role. Participants will be selected on basis of their motivation letter, research experience and career plans. They can choose among 5 categories:
 
1. TB Epidemiology
2. TB diagnostics
3. TB Prevention
4. TB treatment
5. Clinical pearls (case reports)
 
and will be asked to provide a state-of-the-art lecture on their topic or clinical case report together with colleagues from other countries. The presentations will be prepared under guidance of experienced mentors. Apart from keynote lectures and career development sessions there will be a teaching ward round at the national MDR-TB center and visit to the national TB laboratory.
 

The TBNET Academy is open for interested medical students who perform research in the area of tuberculosis or NTM diseases . Clinicans and scientists who apply should have had their last academic exam within 3 years of the application. Distributed representation of participants throughout Europe will be ensured. Participation in the TBNET Academy will be funded with travel/accommodation stipends up to the amount of 500 Euros per person. Travel and accommodation will be booked by the TBNET office for those 20 applicants who will be selected.

Depleting Mycobacterium tuberculosis of the transcription termination factor Rho causes pervasive transcription and rapid death.

 

Authors: 

Laure Botella, Julien Vaubourgeix, Jonathan Livny & Dirk Schnappinger

 

Abstract: 

Rifampicin, which inhibits bacterial RNA polymerase, provides one of the most effective treatments for tuberculosis. Inhibition of the transcription termination factor Rho is used to treat some bacterial infections, but its importance varies across bacteria. Here we show that Rho of Mycobacterium tuberculosis functions to both define the 3' ends of mRNAs and silence substantial fragments of the genome. Brief inactivation of Rho affects over 500 transcripts enriched for genes of foreign DNA elements and bacterial virulence factors. Prolonged inactivation of Rho causes extensive pervasive transcription, a genome-wide increase in antisense transcripts, and a rapid loss of viability of replicating and non-replicating M. tuberculosis in vitro and during acute and chronic infection in mice. Collectively, these data suggest that inhibition of Rho may provide an alternative strategy to treat tuberculosis with an efficacy similar to inhibition of RNA polymerase.

Comments:

Appropriate termination of RNA synthesis is a prerequisite for bacterial viability. The RNA/DNA helicase/translocase Rho is the main termination factor for transcription termination, absent from the genome of eukaryotes and can be selectively inhibited by bicyclomycin (Link). In this study Schnappinger and his team used conditional knockdown mutants to show that Rho from MTB (link) is important for silencing gene expression including insertion elements and phages as well as of PE/PPE genes. More importantly they found that Rho depletion led to a widespread increase of antisense transcription leading to bactericidal effects in vitro as well as in vivo effectively eliminating M. tuberculosis during acute and chronic mouse infection. Rho depletion could also eradicate class II persisters. Currently bicyclomycin is not very active and poorly absorbed when given orally, but targeting Rho from MTB for drug development is promising.

The Tuberculosis Network Clinical Trialsgroup (TBNET), an international consortium of clinicians and scientists, has proposed new treatment outcome definitions for MDR-TB. TBNET documented the management of patients with MDR-TB at 23 different sites across Europe where they found that treatment outcomes according to the definitions proposed by the WHO did not correlate to sustained culture conversion and being free of relapse in the absence of therapy. Applying the novel TBNET MDR-TB outcome criteria “cure” is reached twice as often as compared to the WHO criteria in their study.

 

The number of patients with MDR-TB has dramatically increased worldwide over the past decade. The largest number of patients who have been identified with MDR-TB lives in the WHO region Europe. Chances for “cure” for these patients were thought to be small. In the latest report of the European Centre for Diseases Prevention and Control (ECDC) and the WHO Regional office for Europe, “treatment success” from MDR-TB was less than 50 %. The definition of “treatment success” by the WHO includes patients who are “cured” (having three negative sputum cultures taken at least 30 days apart during the continuation phase of treatment) but also patients who simply “complete the treatment” without failure. An observational follow-up period, to identify disease recurrence in the absence of therapy is not included in the WHO criteria for MDR-TB treatment outcome presently.

 

International cohort with 380 patients

 

As part of the EU Commission funded TB-PANNET project 380 patients with MDR-TB were observed at 23 TBNET centers in countries of high, intermediate and low incidence of TB in Europe over a period of 5 years. Observation started from the time of diagnosis and lasted until one year after the end of the treatment. The researchers found that the WHO criterion for “cure” could not be applied in the majority of patients, simply because most patients who were being treated successfully were not able to produce sputum after 8 months of therapy.

 

TBNET proposed new definitions for “cure” and “failure” of MDR-TB treatment based on the sputum culture status at 6 month after the initiation of therapy and whether patients were free from disease recurrence one year after the end of therapy. “No-one would call a patient with cancer to be cured at the end of chemotherapy. Patients with MDR-TB also need to be closely monitored after the end of treatment to identify patients who experience disease recurrence”, states a TBNET scientists.

 

In their study the results for “cure” from MDR-TB correlate very well with the level of drug resistance and the time to culture conversion. The new definitions are also independent of the total duration of treatment and can be applied to the standard 20 months MDR-TB regimen as well as to the 9-12 months shorter course MDR-TB treatment that was recently proposed by the WHO.

 

Cure-rates from MDR-TB were 61% in this study, compared to only 31% when using the WHO criteria.

 

Hope, but still a lot to be done

 

Results from the TBNET study are encouraging. “There is still a lot to do to improve treatment outcomes in MDR-TB as 1/3 of affected patients still cannot be cured in Europe. The prognosis may be worse in other parts of the world. We are optimistic that outcomes can be improved with novel medicines and individually tailored treatment managements, rather than programmatic fixed combinations of drug-regimens and a one-for-all duration of therapy” says a TBNET spokesman.

TBnet #16 A database for paediatric tuberculosis in Europe Principal investigator: Beate Kampmann (UK) This study was facilitated by the award of the TBnet Grant 2010. The project started in October 2010. The data-base will include (1) demographic characteristics (2) information about active TB and Microbiology (3) LTB (4)Follow-up (5) children with TB contact but not treated and (6) adverse events of treatment. 


TBnet #34 / NTM-NET #5 Treatment of M. xenopi infections (CaMoMy Trial) Principal Investigator: Claire Andrejak

The main objective of this study is to determine the 6-months sputum conversion rate with a clarithromycin- or moxifloxacin-containing regimen in patients with a M. xenopi pulmonary infection. This study is originally located and facilitated in France, other European centers are now asked to participate.


TBnet #39 Differentiation of antigen-specific T-cells in pulmonary tuberculosis Principal Investigator: Barbara Kalsdorf (Germany)

This study aims to characterize the immunophenotype and function of peripheral blood and BAL-derived Mycobacterium (M.) tuberculosis specific T-cells in suspects of tuberculosis to identify whether expansion of antigen-specific T-cells occurs only at a central compartment (lymph nodes) or in addition, at the site of the infection. We will identify the phenotype of unstimulated and antigen-specific T-cells in blood and BAL for the ability to relocate (CD3, CD4, CD8, CD27, CD45RO, CCR7) and to replicate at the site of infection (CD25, IL-2, Ki67). Early apoptosis markers like Annexin V will be used on blood and BAL-cells to investigate whether the local activation of M. tuberculosis-specific CD4 /CD8 T-cells induces protection against cell death in the course of acute pulmonary infection.

Polypharmacy on Pulmonary Tuberculosis treatment

 

If one family consists of 2 adults with Pulmonary Tuberculosis and 3 children with Latent Tuberculosis, then this would result in a mandatory daily dose of 24 tablets, 2 intramuscular injections and 45.5 ml of syrup.

Complying with this is assumed as a major challenge in the treatment of the disease.

Besides the stigma that still brings with it, social isolation that implies obligatory use of a mask to prevent the spread, concerns about 11 and 6 years and 21 months children, plus such immense daily dosages.

The permanent anguish, regarding the children's health, is often the motivation to comply with the treatment. It is desirable, that in the not too distant future, that advances, through research, will concur to minimize the number of medications needed to treat Pulmonary Tuberculosis.

Its all in the head!

Cerebral Tuberculosis - One of the rarest forms of TB, it can be a silent killer!

Until the fatal day when the first symptom of massive seizure occured, my condition could have remained undiagnosed.

Normal TB diagnosis involves blood tests, X-Ray/CT/MRI of all vital organs; here is the catch, all organs except the master controller "The Brain"! Cerebral TB is an atypical, irregular form of TB, alarming to most specialists due to its rarity.

Absolutely no classic symptoms, no pre-warning until the disease had spread so far and so wide.

The initial CT scan showed several lesions with massive inflammation, can take several months to cure.

How did the disease spread? Why could it not be diagnosed earlier and curbed?

There are some questions that remains unswered.

The field of medicine requires belief and patience, the past one year has thought me both.
