TB Journal Club

Monthly online #tuberculosis journal club hosted at research institutions in London & beyond - to join mailing list

[TB Journal Club @Tb_JournalClub]

Join us next on Thursday 24th July at 4pm when the ID team @LNWH_NHS will be hosting!

[TB Journal Club @Tb_JournalClub]

This month Dr Iman Raza chaired by @hanifesmail_tb from @UCLTB presented a TB diagnostic study of LIT-TB, a lab-in-tube system with a portable reading device that targets IS6110 cell-free DNA using recombinase polymerase amplification and CRISPR-Cas12a: https://t.co/V348WyupdR

[TB Journal Club @Tb_JournalClub]

Limitations discussed included serum preparation means not truly POC, no TST+ controls, cannot detect rif resistance, arguably essential for any novel diagnostic, although the authors have found it can be adapted to detect resistant strains (? with ⬇️ sens).

The May TB Journal Club takes place *tomorrow* Thursday 29th, 4pm UK time. Liv-TB will be taking us through https://t.co/xizrCsXNMe trial of pyrazinamide dosing, safety & efficacy. Look forward to seeing you there! #tuberculosis #TB

[TB Journal Club @Tb_JournalClub]

Discussion focussed on the clear importance of Bdq containing regimens, the concerning rise of Bdq-resistance, the poor outcomes associated with it (https://t.co/j1H5Tv6P1t), and the importance of regimens to preserve Bdq.

Join us next month with @NaomiTropMed 22nd May 4pm!

[TB Journal Club @Tb_JournalClub]

This month @mnoursad & @UCLTB presented EndTB's RCT on oral regimens for FQ-sensitive RR-TB https://t.co/e29ZeuKVkR

This 7-country 6-arm open-label Phase III RCT in adults (≥15y) found 9m BLMZ, BCLLfxZ and BDLLfxZ non-inferior to WHO SOC; 1ry endpoint favourable outcome at W73.

[TB Journal Club @Tb_JournalClub]

n=699. 1˚ endpoint favourable outcome @ W73. 12% non-inferiority margin. Pregnancy at enrolment was exclusion. 14% PWH, 57% cavitatory dis. DCMZ non-inferior in mITT only. Phenotypic pyraz resistance >50%.

SAE similar across groups, no deaths considered related to study drugs.

Hope to see you there!

72% would prioritise further research into NAC for individuals with TB - and we were lucky to be joined by @BNadjm who was able to tell us more about plans for a further upcoming trial 🇹🇿🇬🇲🇲🇿

Thanks so much to all who attended and contributed - see you next month.

This Halloween @Mimi_Malhotra & @NaomiTropMed @LSTMnews took us to the spine-chilling world of post-TB lung disease👻 via this RCT of adjunctive NAC https://t.co/rdWytw9WCy

In our straw poll, 11% would consider NAC for their TB patients; 22% said no and 67% wanted more evidence.

See you there!

In this correspondence in @LancetRespirMed we highlight the challenges of inferring TB preventive therapy effectiveness from observational studies: https://t.co/nQPDPhTEcu

A product of the September @Tb_JournalClub... great forum for discussion

@JamesGB_ @mnoursad

[TB Journal Club @Tb_JournalClub]

General discussion: remains important to know differential diagnosis (?malaria ?viral) in different settings, temptation with TDA to maximise sensitivity and risk over-treatment, but this can miss other diagnoses.

Join us on 31st October for the next JC hosted by @LSTMnews!

[TB Journal Club @Tb_JournalClub]

Thanks to @JamesSeddon10 and Ola Joseph yesterday who discussed https://t.co/uUkQKrhQJo

Study in Zambia and Uganda in 603 children offers a one-step (AUC 0.91, Se 86%, Sp 81%) and two-step TDA for initiating TB Rx in hospitalised <5s with sev. malnutrition.

[TB Journal Club @Tb_JournalClub]

Limitations: gap between admissions over study period (1,906) and enrolments (603) ?any bias, inclusion of GXP in TDA despite definitive diagnostic, challenges acquiring all results in reasonable time in real-world setting, lack of gold standard (3/4).
