    Liver Stiffness Measurement Allows Early Diagnosis of Veno-Occlusive Disease/Sinusoidal Obstruction Syndrome in Adult Patients Who Undergo Hematopoietic Stem Cell Transplantation: Results from a Monocentric Prospective Study

    ABSTRACT Veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), is a life-threatening complication affecting patients undergoing hematopoietic stem cell transplantation (HSCT). The survival rate is higher when specific therapy is initiated early; thus, improving early, noninvasive diagnosis of VOD/SOS is an important need. In an adult population undergoing HSCT, we aimed to assess the role of liver stiffness measurement (LSM), evaluated by transient elastography (TE), for diagnosing VOD/SOS. Between April 2016 and March 2018, 78 consecutive adult patients with indications for allogeneic HSCT were prospectively included. LSM was performed before HSCT and at days +9/10, +15/17, and +22/24 post-HSCT. New European Society for Blood and Marrow Transplantation criteria were used to establish VOD/SOS diagnosis. Four patients developed VOD/SOS (5.1%) during the study period, with a median time of +17 days post-HSCT. A sudden increase in LSM compared with previously assessed values and pre-HSCT values, was seen in all patients who developed VOD/SOS. LSM increases occurred from 2 to 12 days before clinical SOS/VOD appearance. The VOD/SOS diagnostic performance of increased LSM over pre-HSCT assessment showed an area under the receiver operating characteristic curve of 0.997 (sensitivity 75%; specificity 98.7%). LSM gradually decreased following successful VOD/SOS-specific treatment. Interestingly, LSM values did not increase significantly in patients experiencing hepatobiliary complications (according to the Common Terminology Criteria) other than VOD/SOS. LSM by TE can be considered a promising method to perform an early, preclinical diagnosis and follow-up of VOD/SOS

    Chemical analysis of pottery demonstrates prehistoric origin for high-altitude alpine dairying

    Get PDF
    The European high Alps are internationally renowned for their dairy produce, which are of huge cultural and economic significance to the region. Although the recent history of alpine dairying has been well studied, virtually nothing is known regarding the origins of this practice. This is due to poor preservation of high altitude archaeological sites and the ephemeral nature of transhumance economic practices. Archaeologists have suggested that stone structures that appear around 3,000 years ago are associated with more intense seasonal occupation of the high Alps and perhaps the establishment of new economic strategies. Here, we report on organic residue analysis of small fragments of pottery sherds that are occasionally preserved both at these sites and earlier prehistoric rock-shelters. Based mainly on isotopic criteria, dairy lipids could only be identified on ceramics from the stone structures, which date to the Iron Age (ca. 3,000 - 2,500 BP), providing the earliest evidence of this practice in the high Alps. Dairy production in such a marginal environment implies a high degree of risk even by today’s standards. We postulate that this practice was driven by population increase and climate deterioration that put pressure on lowland agropastoral systems and the establishment of more extensive trade networks, leading to greater demand for highly nutritious and transportable dairy products
