The objective of this work was to describe the profile of routinely managed tuberculosis patients whose sputum smear did not become negative after the initial phase of anti-tuberculous treatment and to analyze the factors associated with this. With this aim a cross-sectional, retrospective, descriptive and analytical study was carried out in a population of adults with pulmonary tuberculosis (PTB) between 2013 and 2014 in three cities in southern Benin (Cotonou, Porto-Novo and Abomey). The data of the patients who did not convert (PTB +) were compared with those who did (PTB-)...

Rates of migration to Europe, and within Europe, have increased in recent years, with considerable implications for health systems. Migrants in Europe face a disproportionate burden of tuberculosis, HIV, and hepatitis B and C, yet experience a large number of barriers to accessing statutory health care on arrival. A better understanding of how to deliver effective and cost-effective screening, vaccination, and health services to this group is now crucial. We did a systematic review to document and assess the effectiveness and cost-effectiveness of approaches used for infectious diseases screening, and to explore facilitators and barriers experienced by migrants to accessing screening programmes...

Ethionamide (ETH) plays a central role in the treatment of tuberculosis in patients resistant to the first-line drugs. The ETH, thioamide, and thiourea class of antituberculosis agents are pro-drugs that are oxidatively converted to their active S-oxides by the flavin monooxygenase EtaA of M. tuberculosis, thus initiating the chain of reactions that result in inhibition of mycolic acid biosynthesis and cell lysis. As part of a search for new lead candidates, we report here that several xanthates are oxidized by purified EtaA to S-oxide metabolites (perxanthates) that are implicated in the antimycobacterial activity of these compounds...

Ethambutol (EMB) and isoniazid (INH) are the first-line antituberculosis (anti-TB) drugs. However, their neurotoxicity could cause adverse effect and the patients with end-stage renal disease are especially vulnerable due to the reduction in renal drug clearance. Here, we report a 36-year-old man receiving peritoneal dialysis developed progressive paralysis in lower extremities, vision loss and hoarseness 4 months after anti-TB treatment with INH, EMB and rifapentine because of concomitant pulmonary tuberculosis...

Tuberculosis (TB) is an infectious disease that can affect any organ system of the body. Abdominal TB can be gastrointestinal, lymph nodal, visceral or peritoneal. The gallbladder (GB) is rarely involved in abdominal TB as a primary organ. Extensive research literature on gallbladder TB is limited to case reports. There has been no review on this rare abdominal pathology. GB tuberculosis is a difficult diagnosis preoperatively. It is a rare differential among the more common gallbladder pathologies such as cholelithiasis, or a gallbladder malignancy...

BACKGROUND: Cervical lymphadenitis is the most common manifestation of infection with nontuberculous mycobacteria (NTM) in immunocompetent children. Nevertheless, it is poorly known by dermatologists. Its incidence, which is currently increasing since the cessation of BCG vaccination in 2007, raises several issues regarding its pathophysiology, diagnosis and management. PATIENTS AND METHODS: We report two cases of NTM adenitis: one in a 2-year-old girl vaccinated with BCG and one in an unvaccinated 22-month-old boy, in whom a misleading presentation led to delayed diagnosis...

Student contacts of tuberculosis (TB) cases are susceptible to latent tuberculosis infection (LTBI), and chemo-prophylaxis can reduce the risk of active TB among them. This study aimed to assess the acceptance of chemo-prophylaxis for LTBI among students, and their concerns regarding TB and its preventive treatment. A total of 560 students contacts were included in the investigation. The extent of contact was categorized from high to low (4 levels) with 12.9% of the students being close contacts. About 87.0% of the students were willing to receive chemo-prophylaxis if diagnosed with, LTBI, whereas 73 students declined...

Background: The risk of short-term death for treatment naive patients dually infected with Mycobacterium tuberculosis and HIV may be reduced by early anti-retroviral therapy. Of those dying, mechanisms responsible for fatal outcomes are unclear. We hypothesized that greater malnutrition and/or inflammation when initiating treatment are associated with an increased risk for death. Methods: We utilized a retrospective case-cohort design among participants of the ACTG A5221 study who had baseline CD4 < 50 cells/mm3 ...

Multiple issues need to be addressed in order to control the HIV pandemic in sub-Saharan Africa. Combination antiretroviral therapy (cART) is key to reducing morbidity and mortality among people living with HIV and has a role in preventing HIV transmission. However, access to cART is very unevenly distributed globally, especially in sub-Saharan Africa. Although cost of cART is no longer a major barrier as effective treatment can be had for under US$100 per year, HIV management is compromised by the inadequate number of trained clinicians, the lack of clinical and laboratory infrastructure and the increased prevalence of co-morbidities (e...

Tuberculosis (TB), a common chronic-specific granulomatous disease, has become rare in the developed countries. However, it is still a common cause of morbidity and mortality in India. Although it commonly involves the lungs, its presentation in the oral cavity is quite uncommon. The very rare incidence of primary gingival TB, particularly in the absence of active pulmonary involvement often leads to misdiagnosis. Clinical features of oral lesions may include ulceration, nodules, granulomas, and fissures. TB in pregnant women is a major cause of obstetric complications and increased risk of maternal and child mortality...

Extensively drug-resistant (XDR) tuberculosis (TB) poses a threat to public health due to its complicated, expensive and often unsuccessful treatment. A cluster of three XDR TB cases was detected among foreign medical students of a Romanian university. The contact investigations included tuberculin skin testing or interferon gamma release assay, chest X-ray, sputum smear microscopy, culture, drug susceptibility testing, genotyping and whole-genome sequencing (WGS), and were addressed to students, personnel of the university, family members or other close contacts of the cases...

BACKGROUND: Over one million asylum seekers were registered in Germany in 2016, most from Syria and Afghanistan. The Refugee Convention guarantees access to healthcare, however delivery mechanisms remain heterogeneous. There is an urgent need for more data describing the health conditions of asylum seekers to guide best practices for healthcare delivery. In this study, we describe the state of health of asylum seekers presenting to a multi-specialty primary care refugee clinic. METHODS: Demographic and medical diagnosis data were extracted from the electronic medical records of patients seen at the ambulatory refugee clinic in Dresden, Germany between 15 September 2015 and 31 December 2016...

BACKGROUND: Drug resistance in Mycobacterium tuberculosis (MTB) is one of the major challenges in tuberculosis (TB) treatment. However, known mutations cannot explain all of the cases of resistance and little research has focused on the relationship between insertions / deletions (indels) and drug resistance. RESULTS: Here, we retrieved whole genome sequencing data of 743 drug-resistant MTB strains and 367 pan-susceptible strains from TB patients from the public domain to identify novel genomic markers of drug resistance...

Drug-resistant tuberculosis (DR-TB) poses a serious threat to tuberculosis (TB) control in Brazil and worldwide. The current study investigated factors associated with loss to follow-up and death in the course of treatment for DR-TB in a tertiary reference center in the city of Rio de Janeiro, Brazil. This was a retrospective cohort study of cases reported to the Information System on Special Treatments for Tuberculosis (SITETB) from January 1, 2012, to December 31, 2013. A total of 257 patients were reported to the SITETB and initiated treatment for DR-TB...

RATONALE: Sometimes, pleural effusion accompanying an acute Mycoplasma pneumoniae infection or tuberculous pleurisy has similar analysis results. We report a case of tuberculous pleurisy which was initially diagnosed as acute M pneumoniae infection, which is of special interest because anti-Mycoplasma antibody results were positive, which served as a red herring. PATIENT CONCERNS: A 20-year-old woman visited the outpatient emergency romm of our hospital for chief complaints of high fever, dry cough, and pleuralgia persiting for 2 days...

Papua New Guinea (PNG) can be roughly divided into highland, coastal and island peoples with significant mitochondrial DNA differentiation reflecting early and recent distinct migrations from Africa and East Asia, respectively. Infectious diseases such as tuberculosis, malaria and HIV severely impact on the health of its peoples for which drug therapy is the major treatment and pharmacogenetics has clinical relevance for many of these drugs. Although there is generally little information about known single nucleotide polymorphisms in the population, in some instances, their frequencies have been shown to be higher than anywhere worldwide...

Mycobacterium tuberculosis (M.tb) has the extraordinary ability to adapt to the administration of antibiotics through the development of resistance mechanisms. By rapidly exporting drugs from within the cytosol, these pathogenic bacteria diminish antibiotic potency and drive the presentation of drug tolerant tuberculosis (TB). The membrane integrity of M.tb is pivotal in retaining these drug-resistant traits. Silver (Ag) and zinc oxide (ZnO) nanoparticles (NPs) are established antimicrobial agents that effectively compromise membrane stability, giving rise to increased bacterial permeability to antibiotics...
