ReviewAdvances in the management of pulmonary disease due to Mycobacterium abscessus complex.
Mycobacterium abscessus complex is a group of rapidly growing mycobacteria, and an emerging cause of non-tuberculous mycobacterial lung disease in patients with cystic fibrosis and chronic lung diseases, such as bronchiectasis. M. abscessus complex is the most drug-resistant of the mycobacterial pathogens, resulting in limited therapeutic options and a high treatment failure rate. M. abscessus complex is comprised of three closely related subspecies: M. abscessus (sensu stricto), M. massiliense and M. bolletii. ⋯ However, this inducible macrolide resistance is not seen in M. massiliense, as the erm(41) gene of this subspecies is non-functional. Accordingly, treatment success rates with macrolide-based antibiotic treatment are much higher in patients with M. massiliense infections than in those infected with M. abscessus. Precise speciation of M. abscessus complex is important for predicting antibiotic susceptibilities and patient outcome.

Value of adding an IGRA to the TST to screen for latent tuberculous infection in Greek health care workers.
Ioannina University Hospital, Ioannina, Greece. ⋯ Poor overall agreement between TST and QFT-GIT was found. Use of IGRA as a second step in TST-positive cases offers an appropriate tool for LTBI detection among BCG-vaccinated HCWs in low-TB-incidence settings.

LTBI screening in rheumatoid arthritis patients prior to anti-TNF treatment in an endemic area.
Recommendations for screening for latent tuberculous infection (LTBI) in patients eligible for anti-tumour necrosis factor (TNF) agents remain unclear in endemic regions. ⋯ LTBI screening and treatment before anti-TNF treatment is effective in endemic areas and reinforces the importance of establishing contact history for diagnosing LTBI in RA patients.
