We report the case of a 10-year-old child treated for latent tuberculosis infection (LTBI) with pyrazinamide (PZA) and levofloxacin after contact with a smear-positive multidrug-resistant tuberculosis adult. Over the course of the treatment, the patient developed a drug-induced fulminant hepatitis attributed to the combination of PZA and levofloxacin. This case highlights the hepatotoxicity of the association of second-line anti-TB treatment in children.

Conclusions: It is necessary for the Ministerio de Salud y Protección Social and the Instituto Nacional de Salud to promote the use of faster and more sensitive diagnostic tests such as the molecular ones recommended by the World Health Organization. PMID: 31529820 [PubMed - in process]

In this study, we investigated the uptake and biological effects of 2′-OMe PGO in mycobacteria. The results indicated that 2′-OMe PGO specific for the alanine dehydrogenase-encoding ald gene inhibited the growth of Mycobacterium smegmatis and downregulated ald expression at both the transcriptional and translational levels through an RNase H-independent mechanism, showing higher biological activity than its phosphorothioate oligonucleotide counterpart. Confocal microscopy revealed that the anti-ald 2′-OMe PGO was taken up by intracellular mycobacteria residing in RAW 264.7 macrophages without exerting tox...

Abstract Worldwide, tuberculosis (TB) is the leading cause of death due to infection with a single pathogenic agent, Mycobacterium tuberculosis In the absence of an effective vaccine, new, more powerful antibiotics are required to halt the growing spread of multidrug-resistant strains and to shorten the duration of TB treatment. However, assessing drug efficacy at the preclinical stage remains a long and fastidious procedure that delays progression of drugs down the pipeline and towards the clinic. In this investigation, we report the construction, optimization and characterization of genetically engineered near-i...

Over the past decade, the number of patients infected with Mycobacterium tuberculosis resistant to the most effective drugs against tuberculosis (ie, rifampicin and isoniazid), which is called multidrug-resistant tuberculosis, has continued to increase. Globally, 4·6% of patients with tuberculosis have multidrug-resistant tuberculos...

Conclusions: Adherence to ART was higher than to MDR-TB treatment among persons with MDR-TB/HIV coinfection. Missed clinic visits may be a simple measure for identifying patients at risk of unsuccessful MDR-TB treatment outcome.

Abstract A drug resistance survey involving Mycobacterium tuberculosis isolated from patients of a tertiary Hospital in the Rio de Janeiro city (RJ), Brazil, between the years 1996 and 1998 revealed a high frequency of isoniazid (HR) resistance. These isolates were revisited and genotyped. Patients came from different RJ neighborhoods and municipalities, and 70% were outpatients. Applying the 3' and 5' IS 6110 -RFLP and the Spoligotype genotyping methods, the clonal structure of this population was investigated obtaining a snapshot of past epidemiological events. The 3' clusters were subsequently 5' IS 6110 -RFLP ...

Tuberculosis (TB), which is estimated to be the deadliest infectious disease worldwide with ~1.6 million deaths yearly [1], is a clinical issue due to the "ancient" diagnostics and drugs currently available. If compared with the management of other highly prevalent infectious diseases, such as HIV/AIDS and hepatitis C virus infection, it is clear that the clinical approach for TB disease requires innovation, being still based on means with limited efficacy (e.g. treatment of multidrug-resistant TB; MDR-TB), and characterised by the denominator "long duration": conventional bacteriological diagnosis, the...
