Crohn ’s disease (CD) is an uncommon disease in Thai population, leading to delay in diagnosis due to lacking of familiarity, which may increase disease complications. One of the most problematic issues is to differentiate CD from intestinal tuberculosis (ITB), and many scoring systems have been introdu ced since 2006. However, competency of diagnosis of CD in the latter period is still unknown in Thailand. Our aim is to compare this competency in the period of 2000-2006, 2007-2012, and 2013-2018.

Biological agents have revolutionized the management of inflammatory bowel disease (IBD). There is a known increased risk of tuberculosis (TB) reactivation with biologic therapy (1). ACG guidelines recommend screening for active and latent TB infection (LTBI) prior to starting certain biologic agents (2). However, there are no consensus guideline on the utility of yearly screening testing in IBD patients without TB risk factors. With a number of patients now receiving the biologic therapy outside their primary care centers it has become increasingly difficult to effectively provide ongoing TB screening.

By SAURABH JHA, MD Clever Hans Preetham Srinivas, the head of the chest radiograph project in Qure.ai, summoned Bhargava Reddy, Manoj Tadepalli, and Tarun Raj to the meeting room. “Get ready for an all-nighter, boys,” said Preetham. Qure’s scientists began investigating the algorithm’s mysteriously high performance on chest radiographs from a new hospital. To recap, the algorithm had an area under the receiver operating characteristic curve (AUC) of 1 – that’s 100 % on multiple-choice question test. “Someone leaked the paper to AI,” laughed Manoj. “I...

ConclusionsThis developed population pharmacokinetic model can be used to calculate cycloserine concentrations and exposure in patients with multidrug-/extensively drug-resistant tuberculosis. This model was successfully validated by internal and external validation methods. This study showed that the AUC0 –24 h of cycloserine can be estimated in patients with multidrug-/extensively drug-resistant tuberculosis using a 1- or 2-point limited sampling strategy in combination with the developed population pharmacokinetic model. This strategy can be used in studies to correlate drug exposure with clinical outcome. Th...

BCG vaccination is an important global health measure in countries with endemic tuberculosis but poses significant risks when administered to patients with Severe Combined Immune Deficiency (SCID) or genetic defects associated with Mendelian Susceptibility to Mycobacterial Diseases (MSMD). A study by Marciano et al. reported that BCG-osis occurred in over 50% of BCG-vaccinated patients with SCID. The impact of this infection on allogeneic hematopoietic stem cell transplant (HSCT) outcomes is unclear.

CONCLUSIONS.: There is a great variability of mutations associated with resistance to anti-tuberculosis drugs that have been reported in Peru, and they are systematized in this report. These mutations must be taken into account for the development of diagnostic devices or selection of diagnostic tests to be applied in our country. PMID: 31967255 [PubMed - in process]

AbstractTuberculosis (TB) caused by resistant strains is becoming a public health concern also in high-income countries. In Pavia province, Northern Italy, the prevalence of foreign-born has increased in recent years. Nevertheless, it is unclear if this has modified epidemiology and resistance patterns ofMycobacterium tuberculosis. We retrospectively collected data on all theMycobacterium tuberculosis strains isolated by culture in the microbiology reference laboratory of the province of Pavia from 01/01/1998 to 31/12/2017. Overall, 919 patients were identified, 320 were foreign-born (34.8%). The proportion of cases due to...

AbstractThe epidemiology of non-tuberculous mycobacteria (NTM) in Spain is largely unknown because systematic reporting is not compulsory. The aim of our study was to describe the frequency and diversity of NTM species in our region and their distribution according to the source sample, gender, and age of the patients. We performed a multicenter study of all NTM isolated in 24 public hospitals in Madrid from 2013 to 2017. A total of 6.923 mycobacteria were isolated: 4535 (65.5%) NTM, and 2.388 (34.5%)Mycobacterium tuberculosis complex (MTB). Overall, 61 different NTM species were identified. The most frequently isolated sp...
