In this report, we present a case with presumed unilateral tuberculosis uveitis from an endemic region. A 23-year-old male presented with decreased vision in his left eye for 15 days. Visual acuities were 1.0 in his right eye and 0.3 in his left eye. Ophthalmologic examination was normal for the right eye. Slit-lamp examination revealed 2+ cells in the vitreous without anterior chamber reaction in his left eye. Fundus examination revealed occlusive vasculitis and granuloma. His history revealed that he had a respiratory infection with fever 3 months ago while visiting his native country, Rwanda, and was treated with non-specific antibiotic therapy...

BACKGROUND: When planning a study to estimate disease prevalence to a pre-specified precision, it is of interest to minimize total testing cost. This is particularly challenging in the absence of a perfect reference test for the disease because different combinations of imperfect tests need to be considered. We illustrate the problem and a solution by designing a study to estimate the prevalence of childhood tuberculosis in a hospital setting. METHODS: All possible combinations of 3 commonly used tuberculosis tests, including chest X-ray, tuberculin skin test, and a sputum-based test, either culture or Xpert, are considered...

BACKGROUND: Systematic screening is often proposed as a way to improve case finding for tuberculosis (TB), but the cost-effectiveness of specific strategies for systematic screening remains poorly studied. METHODS: We constructed a Markov-based decision analytic model to analyse the cost-effectiveness of triage testing for TB in Uganda, compared against passive case detection with Xpert MTB/RIF. We assumed a triage algorithm whereby all adults presenting to healthcare centres would be screened for cough, and those with cough of at least 2 weeks would receive the triage test, with positive triage results confirmed by Xpert MTB/RIF...

BACKGROUND: Kanamycin, an injectable agent, is currently used to treat drug-resistant tuberculosis (TB). Parenteral kanamycin causes high systemic toxicity which could be avoided by direct delivery to the lungs. This study focused on producing a highly aerosolizable dry-powder of hygroscopic kanamycin by spray-drying with l-leucine. METHODS: Kanamycin powders were prepared with different concentrations (0, 5, 10, 15 and 20% w/w) of l-leucine using the Buchi B-290 Mini Spray-Dryer...

Psoriatic patients with latent tuberculosis infection (LTBI) need a prophylaxis before starting a treatment with biological drugs. The aim of this study is to investigate the safety and efficacy of prophylaxis of LTBI in psoriatic patients receiving long-term biological drugs. The study included 56 patients (42 male and 14 female) affected by moderate-to-severe psoriasis (mean PASI: 12.8 ± 6.9 SD) treated with anti-TNF-α and/or anti IL 12, 23 and/or anti-CD11 drugs with a diagnosis of LTBI. LTBI diagnosis was based on tuberculin skin test and/or QuantiFERON TB Gold test positivity and chest X-ray suggestive, without clinical, or microbiological evidence of active disease...

BACKGROUND: The carbapenem subclass of β-lactams is among the most potent antibiotics available today. Emerging evidence shows that, unlike other subclasses of β-lactams, carbapenems bind to and inhibit non-classical transpeptidases (L,D-transpeptidases) that generate 3 → 3 linkages in bacterial peptidoglycan. The carbapenems biapenem and tebipenem exhibit therapeutically valuable potencies against Mycobacterium tuberculosis (Mtb). RESULTS: Here, we report the X-ray crystal structures of Mtb L,D-transpeptidase-2 (LdtMt2) complexed with biapenem or tebipenem...

BACKGROUND: High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics...

Several ruthenium complexes have been investigated regarding anti-Mycobacterium tuberculosis (anti-MTb) activity, with some diphosphine-containing ruthenium complexes comparable to first and second line drugs. However, to the best of our knowledge, there is no PNP-containing ruthenium complexes applied as metallodrugs. Thus, this study focused on the synthesis, characterization and anti-MTb activity of a new series of coordination compounds with general formula [RuCl(η(6)-p-cymene)(PN(R)P)]X (R=CH2Py (Py=pyridine)-[1a], CH2Ph (Ph=phenyl)-[1b], Ph-[1c] and p-tol (p-tol=p-tolyl)-[1d]; X=PF6(-) or BF4(-))...

Native nanoelectrospray ionization mass spectrometry is an underutilized technique for fragment screening. In this study, the first demonstration is provided of the use of native mass spectrometry for screening fragments against a protein-DNA interaction. EthR is a transcriptional repressor of EthA expression in Mycobacterium tuberculosis (Mtb) that reduces the efficacy of ethionamide, a second-line antitubercular drug used to combat multidrug-resistant Mtb strains. A small-scale fragment screening campaign was conducted against the EthR-DNA interaction using native mass spectrometry, and the results were compared with those from differential scanning fluorimetry, a commonly used primary screening technique...

Mycobacteria employ a versatile machinery of the mycothiol-dependent system, containing the proteins mycothiol disulfide reductase (Mtr), the oxido-reductase Mycoredoxin-1 (Mrx-1) and the alkyl-hydroperoxide subunit E (AhpE). The mycothiol-dependent protein ensemble regulates the balance of oxidized-reduced mycothiol, to ensure a reductive intracellular environment for optimal functioning of its proteins even upon exposure to oxidative stress. Here, we determined the first low-resolution solution structure of Mycobacterium tuberculosis Mtr (MtMtr) derived from small-angle X-ray scattering data, which provides insight into its dimeric state...

The F1FO ATP (F-ATP) synthase is essential for growth of Mycobacterium tuberculosis, the causative agent of tuberculosis (TB). In addition to their synthase function most F-ATP synthases possess an ATP-hydrolase activity, which is coupled to proton-pumping activity. However, the mycobacterial enzyme lacks this reverse activity, but the reason for this deficiency is unclear. Here, we report that a Mycobacterium-specific, 36 amino acid long C-terminal domain in the nucleotide-binding subunit α (Mtα) of F-ATP synthase suppresses its ATPase activity and determined the mechanism of suppression...
