Autologous Hematopoietic Stem Cell Transplantation (AHSCT): Standard of Care for Relapsing–Remitting Multiple Sclerosis Patients

Abstract Autologous hematopoietic stem cell transplantation (AHSCT) has been used in the treatment of highly active multiple sclerosis (MS) for over two decades. It has been demonstrated to be highly efficacious in relapsing–remitting (RR) MS patients failing to respond to disease-modifying drugs (DMDs). AHSCT guarantees higher rates of no evidence of disease activity (NEDA) than those achieved with any other DMDs, but it is also associated with greater short-term risks which have limited its use. In the 2019 updated EBMT and ASBMT guidelines, which review the clinical evidence of AHSCT in MS, AHSCT indication for highly active RRMS has changed from “clinical option” to “standard of care”. On this basis, AHSCT must be proposed on equal footing with second-line DMDs to patients with highly active RRMS, instead of being considered as a last resort after failure of all available treatments. The decision-making process requires a close collaboration between transplant hematologists and neurologists and a full discussion of risk–benefit of AHSCT and alternative treatments. In this context, we propose a standardized protocol for decision-making and informed consent process

Assessment of food contamination and dietary intake of lead and thallium in a Northern Italy population.

Lead and thallium are heavy metals released in the environment after natural and anthropogenic activities. Food and water intake are the major sources of human exposure to these elements. In this study, we aimed at characterizing lead and thallium content in foods consumed in Northern Italy population, in order to estimate the dietary intake of these metals. To do that we bought food samples in markets and groceries collected during the period from October 2016 to February 2017 in the Emilia Romagna region, and we measured their element content using inductively coupled plasma-mass spectrometry. Finally, after assessing dietary habits of an Emilia-Romagna community by using a validated food frequency questionnaire, we eventually estimated dietary intake of these metals in that community. In the 890 analyzed food samples, the highest lead contamination levels were found in seafood, vegetables, sweets and beverages. The estimated dietary intake of lead was 5.758 (interquartile range-IQR: 4.547-7.427) µg/day, corresponding to 0.089 (IQR: 0.069-0.113) µg/kg of body weight per day, with cereals, beverages and vegetables as major contributors. About thallium, one third of specimens showed very low levels below the limit of detection, with the highest contamination levels in vegetables, dry fruits and sweets. The dietary intake of thallium was 0.236 (IQR: 0.183-0.312) µg/day, mainly from vegetables, beverages, cereals and sweets. In conclusion, our study provides an estimation of lead and thallium intake in a Northern Italian community and shows a generally low exposure levels from dietary sources

Dietary intake of calcium, phosphorus and magnesium in a Northern Italian community.

Minerals are essential micronutrients for growth, development, and maintenance of healthy tissues, the long term insufficient intake of minerals may lead to bone demineralization and often requires the use of food supplements. The ratios of certain minerals intake like calcium and phosphorus are also proved to can affect the bioavailability of calcium and even lead to adverse health consequence. This study was designed to explore the dietary sources of calcium (Ca), phosphorus (P), and magnesium (Mg) and the ratios between different minerals (Ca/P). We measured the content of these elements in foods composing typical Italian diet using inductively coupled plasma-mass spectrometry and we estimated their daily dietary intakes assessing through a semi-quantitative food frequency questionnaire specifically developed within the European Prospective Investigation into Cancer and Nutrition (EPIC) study in a Northern Italian Community. In 890 analyzed food samples the main contributors to calcium are milk and dietary products, dry fruits, legumes and sweet products. Important sources of phosphorus are represented by dry fruits, legumes, milk and dairy products and meat. While dry fruits, legumes, cereals and fish symbolized the most important sources for magnesium. In our Italian population sample, the estimated median (interquartile range) dietary daily intakes are 786.3 (592.2-1062.7) μg/day for calcium; 1291.7 (1017.2-1591.4) mg/day for phosphorus and 323.2 (260.3-396.6) mg/day for magnesium. The calcium-phosphorus (Ca/P) ratio in this study was 0.63 (0.52-0.73). These values are in agreement with those suggested by European and International recommended intake for adult population, with the exception of calcium which is slightly lower than recommended values and suggest that this population does not present nutritional deficiencies requiring any supplementation

NF-κB dysregulation in microRNA-146a–deficient mice drives the development of myeloid malignancies

MicroRNA miR-146a has been implicated as a negative feedback regulator of NF-κB activation. Knockout of the miR-146a gene in C57BL/6 mice leads to histologically and immunophenotypically defined myeloid sarcomas and some lymphomas. The sarcomas are transplantable to immunologically compromised hosts, showing that they are true malignancies. The animals also exhibit chronic myeloproliferation in their bone marrow. Spleen and marrow cells show increased transcription of NF-κB–regulated genes and tumors have higher nuclear p65. Genetic ablation of NF-κB p50 suppresses the myeloproliferation, showing that dysregulation of NF-κB is responsible for the myeloproliferative disease
