Impact of country of origin on drug-resistant tuberculosis among foreign-born persons in British Columbia.

SETTING: Provincial tuberculosis (TB) services, British Columbia, Canada. OBJECTIVES: To estimate the risk of drug resistance among foreign-born TB patients and to identify risk factors associated with drug resistance. DESIGN: Using the provincial TB database, we examined all culture-positive foreign-born TB patients for the years 1990-2001. The risk of having a drug-resistant isolate was estimated according to country and region of origin. RESULTS: Of 1940 foreign-born patients identified, 247 (12.7%, 95%CI 11.3-14.3) cases had isolates resistant to at least one of the first-line drugs, wi

Gut Microbiota Condition the Therapeutic Efficacy of Trastuzumab in HER2-Positive Breast Cancer.

Emerging evidence indicates that gut microbiota affect the response to anticancer therapies by modulating the host immune system. In this study, we investigated the impact of gut microbiota on immune-mediated trastuzumab antitumor efficacy in preclinical models of HER2-positive breast cancer and in 24 patients with primary HER2-positive breast cancer undergoing trastuzumab-containing neoadjuvant treatment. In mice, the antitumor activity of trastuzumab was impaired by antibiotic administration or fecal microbiota transplantation from antibiotic-treated donors. Modulation of the intestinal micr

Tuberculosis treatment outcome and predictors in northern Ethiopian prisons: a five-year retrospective analysis.

BACKGROUND: The prison situations are notorious for causing interruptions of tuberculosis (TB) treatment and occurrence of unfavorable outcomes. In Ethiopian prisons, though TB treatment programs exist, treatment outcome results and factors contributing to unsuccessful outcome are not well documented. In this study, we assessed the treatment outcome of TB cases and identified risk factors for unsuccessful outcome in northern Ethiopian prisons. METHODS: A retrospective record review was conducted for all prisoners diagnosed with TB between September 2011 and August 2015. Outcome variables were

Chronic Brucella Infection Induces Selective and Persistent Interferon Gamma-Dependent Alterations of Marginal Zone Macrophages in the Spleen.

The spleen is known as an important filter for blood-borne pathogens that are trapped by specialized macrophages in the marginal zone (MZ): the CD209+ MZ macrophages (MZMs) and the CD169+ marginal metallophilic macrophages (MMMs). Acute systemic infection strongly impacts MZ populations and the location of T and B lymphocytes. This phenomenon has been linked to reduced chemokine secretion by stromal cells. Brucella spp. are the causative agent of brucellosis, a widespread zoonotic disease. Here, we used Brucella melitensis infection as a model to investigate the impact of chronic stealth infec

Critically timed ethanol exposure reduces GABAAR function on septal neurons developing in vivo but not in vitro.

Six-day 'binge' ethanol intoxication postnatal days (PD) 4-9 delays up-regulation of gamma-aminobutyric acid type A receptors (GABAARs) in developing rat septal neurons [Dev. Brain Res. 130 (2001) 25]. This distortion occurs during synaptogenesis and could contribute to cognitive dysfunction in fetal alcohol syndrome (FAS). Here, we asked two questions concerning requirements for vulnerability to GABAAR blunting by ethanol. First, we asked whether receptor blunting required PD 4-9 ethanol exposure in rat pups and found that just a brief 2-day exposure (PD 8-9) was as effective as all 6 days. H

[Agranulocytosis due to anti-tuberculosis drugs including isoniazid (INH) and rifampicin (RFP)--a report of four cases and review of the literature].

We experienced 4 cases of agranulocytosis due to anti-tuberculosis drugs (rifampicin [RFP], isoniazid [INH], ethambutol [EB], streptomycin [SM] or pyrazinamide [PZA]) among some 6,400 tuberculosis patients who underwent chemotherapy over the past 20 years from 1981 to 2002 in our hospital, and the incidence rate of agranulocytosis was estimated at 0.06%. The 4 cases of agranulocytosis were as follows. CASE 1: A 51-year-old woman with right chest pain and fever was admitted to our hospital on Jan 4, 2001. The white blood cell (WBC) count was 5,200/microliter. The tubercle bacilli were cultured …

MSC-EV therapy for bone/cartilage diseases.

Mesenchymal stromal cells (MSCs) have been utilized in cell therapy for various diseases. Recent studies have demonstrated that extracellular vesicles (EVs) released by MSCs play an important role in their therapeutic activities. EVs contain a variety of bioactive molecules such as proteins, messenger RNAs (mRNAs), and micro RNAs (miRNAs) and modify the function of the recipient cells by transferring these molecules. Despite the promising potential of EV therapy as a substitute for MSC therapy, there are challenges that need to be addressed for the clinical success of EV therapy. EV quality ha

Regulatory B cells induced by pancreatic cancer cell-derived interleukin-18 promote immune tolerance via the PD-1/PD-L1 pathway.

Dysregulation of regulatory B cells (Bregs), a type of immunosuppressive lymphocyte, are associated with development of autoimmune diseases and cancers. Bregs produce immune tolerance-inducing cell surface molecules and tolerogenic cytokines (interleukin [IL]-10 and transforming growth factor-beta). We previously showed that levels of the inflammatory cytokine IL-18 were increased in patients with pancreatic cancer. In the present study study, we found that pancreatic cancer cell-derived IL-18 increases Breg-induced immunosuppression. IL-18 also promoted B-cell proliferation and IL-10 expressi
