New Therapeutic Approach in an Infant With Systemic Myofibromatosis and Intestinal Hemorrhage.

Published: April 2022

We report the case of an infant with multicentric myofibromatosis affecting the gastric and intestinal mucosa, leading to continuous intestinal hemorrhage and iron deficiency. Conventional vinblastine and methotrexate combination treatment was administered for 4 months, but persistent intestinal blood loss required repeated blood transfusions. Because of insufficient tumor response to treatment, we opted for the experimental combination of rapamycin and dasatinib. Six weeks after the start of this therapy, hemoglobin levels stabilized without transfusions, and no fecal blood loss was detected. In addition, a follow-up magnetic resonance imaging excluded tumor progression. We here show the effectiveness of an experimental therapy with rapamycin and dasatinib in a child with multicentric myofibromatosis after the failure of conventional therapy with vinblastine and methotrexate.

Diabetic nephropathy (DN) is one of the most serious and prevalent complications associated with diabetes. Consequently, antidiabetic drugs or foods potentially protecting the kidneys are of significant therapeutic value. Sulforaphene (SFE) is a natural isothiocyanate derived from radish seeds, known for its anti-inflammatory and antioxidant properties.

The research aimed to evaluate the effects of a commercial blend of phytogenic compounds on the digestibility, antioxidant system, intestinal microbiota, and performance of weaned piglets. Two experiments compared three treatments (diets): control, zinc bacitracin (300 g/t) and blended phytogenic compounds (400 g/t). The first experiment analised of digestibility of the dry matter, organic matter, crude protein, crude energy and metabolizable energy, in addition to blood parameters and gut microbiota in 15 piglets commercial cross-bred, weaned at 28 days of age, castrated males, weighing 9.

The gut microbiota is a complex and dynamic ecosystem that plays a crucial role in human health and disease, including obesity, diabetes, cardiovascular diseases, neurodegenerative diseases, inflammatory bowel disease, and cancer. Chronic inflammation is a common feature of these diseases and is closely related to angiogenesis (the process of forming new blood vessels), which is often dysregulated in pathological conditions. Inflammation potentially acts as a central mediator.

Polysaccharides from Yupingfeng granules ameliorated cyclophosphamide-induced immune injury by protecting intestinal barrier.

Immune injury is the main side effect caused by cyclophosphamide and the disruption of the intestinal barrier may be an important cause. Yupingfeng granules have been reported to have immunomodulatory effects and polysaccharides are important components of them. This study aimed to investigate the ameliorative effect of polysaccharides from Yupingfeng granules (YPFP) on cyclophosphamide induced immune injury and reveal their potential mechanisms based on its protective effect on the intestine.
