RESUMO
BACKGROUND: Despite multiple therapy regimens, the decline in the Helicobacter pylori eradication rate poses a significant challenge to the medical community. Adding Lactobacillus reuteri probiotic as an adjunct treatment has shown some promising results. This study aims to investigate the efficacy of Lactobacillus reuteri DSM 17648 in H. pylori eradication and its effect in ameliorating gastrointestinal symptoms and adverse treatment effects. MATERIALS AND METHODS: This randomized, double-blinded, placebo-controlled trial involved treatment-naïve H. pylori-positive patients. Ninety patients received standard triple therapy for 2 weeks before receiving either a probiotic or placebo for 4 weeks. The posttreatment eradication rate was assessed via a 14 C urea breath test in Week 8. The Gastrointestinal Symptom Rating Scale (GSRS) questionnaire and an interview on treatment adverse effects were conducted during this study. RESULTS: The eradication rate was higher in the probiotic group than in the placebo group, with a 22.2% difference in the intention-to-treat analysis (91.1% vs. 68.9%; p = 0.007) and 24.3% difference in the per-protocol analysis (93.2% vs. 68.9%; p = 0.007). The probiotic group showed significant pre- to post-treatment reductions in indigestion, constipation, abdominal pain, and total GSRS scores. The probiotic group showed significantly greater reductions in GSRS scores than the placebo group: indigestion (4.34 ± 5.00 vs. 1.78 ± 5.64; p = 0.026), abdominal pain (2.64 ± 2.88 vs. 0.89 ± 3.11; p = 0.007), constipation (2.34 ± 3.91 vs. 0.64 ± 2.92; p = 0.023), and total score (12.41 ± 12.19 vs. 4.24 ± 13.72; p = 0.004). The probiotic group reported significantly fewer adverse headache (0% vs. 15.6%; p = 0.012) and abdominal pain (0% vs. 13.3%; p = 0.026) effects. CONCLUSIONS: There was a significant increase in H. pylori eradication rate and attenuation of symptoms and adverse treatment effects when L. reuteri was given as an adjunct treatment.

Severe facial burns cause significant deformities that are technically challenging to treat. Conventional treatments almost always result in poor aesthetic and functional outcomes. This is due to the fact that current treatments cover or replace the delicate anatomical facial tissues with autologus grafts and flaps from remote sites. The recent introduction of clinical composite tissue allotransplantation (CTA) that uses healthy facial tissue transplanted from donors to reconstruct the damaged or non-existing facial tissues with original tissues makes it possible to achieve the best possible functional and aesthetic outcomes in these challenging injuries. The techniques required to perform this procedure, while technically challenging, have been developed over many years and are used routinely in reconstructive surgery. The immunosuppressive regimens necessary to prevent transplanted facial tissue from rejecting (tacrolimus/mycophenolate mofetil/steroid) were developed for and have been used successfully in solid organ transplants for many years. The psychosocial and ethical issues associated with this new treatment have some nuances but generally have many similarities with solid organ and more recently hand transplantation, both of which have been performed clinically for 40 and 10+ years respectively. Herein, we will discuss the technical and immunological aspects of facial tissue transplantation. The psychosocial and ethical issues will be discussed separately in another article in this issue.
