https://www.selleckchem.com/products/sodium-l-lactate.html The goal of this review is to firstly address the concept of chimeric antigen receptor T-cell (CAR T-cell) therapy and where it fits in the evolving landscape of the management of patients with refractory/relapsed diffuse large B-cell lymphoma. The recognition of the indications for CAR T-cell therapy for patients with aggressive B-cell lymphoma will be discussed, including a review of the algorithms and selection criteria for CAR T-cell therapy and finally, the role of bridging therapy and the timing of CAR T-cell therapy in augmenting chances of a successful outcome.BACKGROUND Probiotics are known to stimulate the immune system but the effect on thymus size in late infancy is unknown. We examined the effect of probiotics on thymus size and C-reactive protein (CRP) in healthy Danish infants starting daycare. We further examined associations between thymus size, CRP and recent infections. METHODS The study included 186 children randomized to a combination of Lactobacillus rhamnosus, LGG® and Bifidobacterium animalis spp. lactis, BB-12® or placebo for 6 months. Thymus size, assessed as thymus index (TI) and thymus weight index (TWI), was measured by ultrasound at baseline and at endpoint. Blood samples were drawn to measure CRP. Infections were parent-reported. RESULTS There was no significant difference in thymus size between the probiotic group and placebo (p ≥ 0.248) but TWI tended to be higher in the probiotic group corresponding to 5% higher than placebo (p = 0.068) in an adjusted model. There was no effect of probiotics on CRP (p = 0.331). At the endpoint, thymus size was inversely associated with CRP (p ≤ 0.040), diarrhea (p ≤ 0.050), and TI was also associated with the absence from daycare due to respiratory or gastrointestinal infections (p = 0.010). CONCLUSION The probiotic intervention had no effect on thymus size or CRP in Danish children at the age of starting daycare. IMPACT Overall there was no
