Leukocyte-adhesion deficiency-1 is a recessively inherited disorder associated with recurrent bacterial infections, severe periodontitis, peripheral leukocytosis, and impaired wound healing. We diagnosed moderate-type leukocyte-adhesion deficiency-1 in a 7-year-old girl who developed a necrotizing ulcer after Bacillus Calmette-Guerin vaccination. The patient showed moderate expression of CD18 in neutrophils with a homozygous splice mutation with c.41_c.58+2dup20 of ITGB2 and experienced recurrent severe infections complicated with systemic lupus erythematosus...

BACKGROUND: Oxidative stress produces molecular modifications of serum albumin that disturb its biological functions and interfere with its detection by the bromocresol green assay (BCG). Oxidative stress, inflammation, and hypoalbuminemia are common peritoneal dialysis (PD). This study aimed to evaluate the relationship between serum albumin, oxidized serum albumin (OSA), oncotic pressure, and blood pressure in hypoalbuminemic PD patients. METHODS: Twenty-four PD patients with serum albumin levels <3...

Bacillus Calmette-Guérin (BCG) is the only available vaccine against tuberculosis. Although its protective efficacy against pulmonary tuberculosis is still under debate, it provides protection against other mycobacterial diseases. BCG is also an effective therapy against superficial bladder cancer and potentially decreases overall childhood mortality. Areas covered. The purpose of this paper is to provide a state-of-the-art summary of the beneficial effects of BCG in inflammatory and auto-immune diseases. As a strong inducer of Th1 type immunity, BCG has been reported to protect against atopic conditions, such as allergic asthma, a Th2-driven disorder...

Accurate estimates of Mycobacterium tuberculosis (M.tb) infection in young children provide a critical indicator of on-going community M.tb transmission. Cross reactions due to infection with environmental mycobacteria and/or Bacille Calmette-Guérin (BCG) vaccination compromise the estimates derived from population-level tuberculin skin test surveys using traditional cut-off methods. Newer statistical approaches are prone to failure of model convergence, especially in settings where the prevalence of M.tb infection is low and environmental sensitisation is high...

In order to develop an improved BCG vaccine against tuberculosis we have taken advantage of the adjuvant properties of a non-toxic derivative of Escherichia coli heat labile enterotoxin (LT), LTAK63. We have constructed rBCG strains expressing LTAK63 at different expression levels. Mice immunized with BCG expressing low levels of LTAK63 (rBCG-LTAK63lo) showed higher Th1 cytokines and IL-17 in the lungs, and when challenged intratracheally with Mycobacterium tuberculosis displayed a 2.0-3.0 log reduction in CFU as compared to wild type BCG...

Tuberculosis (TB) is a contagious, infectious disease, due to Mycobacterium tuberculosis (MT) that has always been a permanent challenge over the course of human history, because of its severe social implications. It has been hypothesized that the genus Mycobacterium originated more than 150 million years ago. In the Middle Ages, scrofula, a disease affecting cervical lymph nodes, was described as a new clinical form of TB. The illness was known in England and France as "king's evil", and it was widely believed that persons affected could heal after a royal touch...

Immunotherapy, via intra-vesical instillations of BCG, is the therapy of choice for patients with high-risk non-muscle invasive bladder cancer. The subsequent recruitment of lymphocytes and myeloid cells, as well as the release of cytokines and chemokines, is believed to induce a local immune response that eliminates these tumors, but the detailed mechanisms of action of this therapy are not well understood. Here, we have studied the phenotype and function of the responding lymphocyte populations as well as the spectrum of cytokines and chemokines produced in an in vitro model of human peripheral blood mononuclear cells (PBMCs) co-cultured with BCG...

The humanized mouse model has been developed as a model to identify and characterize human immune responses to human pathogens and has been used to better identify vaccine candidates. In the current studies, the humanized mouse was used to determine the ability of a vaccine to affect the immune response to infection with Mycobacterium tuberculosis. Both human CD4(+) and CD8(+) T cells responded to infection in humanized mice as a result of infection. In humanized mice vaccinated with either BCG or with CpG-C, a liposome-based formulation containing the M...

BACKGROUND: Tuberculosis (TB) remains a significant global health concern and its diagnosis is challenging due to the limitations in the specificity and sensitivity of the current diagnostic tests. Exosomes are bioactive 30-100 nm vesicles produced by most cell types and are found in almost all human body fluids. Exosomal microRNAs (miRNAs) can transfer biological information between cells and tissues and may act as potential biomarkers in many diseases. In this pilot study, we assessed the miRNA profile of exosomes released from human monocyte-derived macrophages upon infection with Mycobacterium bovis Bacillus Calmette-Guerin (BCG)...

BACKGROUND: Development of a tuberculosis vaccine to boost BCG is a major international health priority. SRL172, an inactivated whole cell booster derived from a non-tuberculous mycobacterium, is the only new vaccine against tuberculosis to have demonstrated efficacy in a Phase 3 trial. In the present study we sought to determine if a three-dose series of DAR-901 manufactured from the SRL172 master cell bank by a new, scalable method was safe and immunogenic. METHODS: We performed a single site, randomized, double-blind, controlled, Phase 1 dose escalation trial of DAR-901 at Dartmouth-Hitchcock Medical Center in the United States...

Cytotoxic chemotherapy has been the only systemic treatment of locally advanced and metastatic urothelial carcinoma for decades. Long-term survival remains stagnant around 12-14 months for patients with advanced disease who have progressed on or recurred after receiving first-line platinum-based chemotherapy. Improving clinical outcomes for patients with urothelial carcinoma in all disease settings requires the development of novel treatments, especially for patients who failed on first-line chemotherapy. Since the discovery of intravesical Bacillus-Calmette Guerin (BCG) in the 1970s for non-muscle invasive disease, there have not been any major breakthrough drugs that exploit the immune-sensitivity of bladder cancer until recently...
