Polysorbate 80, a sorbitan derivate, is a surfactant used as an emulsifier in some foods in concentrations of up to 0.5%. It was recently shown in vitro that polysorbate 80 decreases the minimum bactericidal concentrations of clarithromycin and metronidazole and may also revert antibiotic resistance.

The spliceosome accurately promotes precursor messenger-RNA splicing by recognizing specific noncoding intronic tracts including the branch point sequence (BPS) and the 3'-splice-site (3'SS). Mutations of Hsh155 (yeast)/SF3B1 (human), which is a protein of the SF3b factor involved in BPS recognition and induces altered BPS binding and 3'SS selection, lead to mis-spliced mRNA transcripts. Although these mutations recur in hematologic malignancies, the mechanism by which they change gene expression remains unclear.

The diagnosis of small intestinal bacterial overgrowth: Two steps forward, one step backwards?

Neurogastroenterol Motil

November 2018

Lynda K and David M Underwood Center for Digestive Disorders, Division of Gastroenterology and Hepatology, Houston Methodist Hospital and Weill Cornell Medical College, Houston, Texas.

Small intestinal bacterial overgrowth (SIBO) was originally described decades ago as a cause of malabsorption among individuals with abnormal intestinal anatomy and/or impaired gastric acid secretion and intestinal motor functions. More recently, the concept of SIBO has been expanded to explain symptoms among a much broader patient population-a move that brings the definition of SIBO into much sharper focus. For largely logistical reasons, breath tests and, especially, those based on the excretion of hydrogen consequent on the fermentation of unabsorbed carbohydrate substrates, have almost entirely replaced jejunal aspirates in the diagnosis of SIBO.

Background: A clinically meaningful impairment of bone mass secondary to malabsorption is frequent in untreated celiac disease. In adult patients, a rigorous gluten-free diet (GFD) significantly improves, but does not always normalize, bone mineral density (BMD). The reason for this marginal response is unclear.

In irritable bowel syndrome, postprandial abdominal distention is associated with a reduction of intestinal tone.

Neurogastroenterol Motil

October 2017

Department of Internal Medicine, IRCCS "S. Matteo" Hospital Foundation, University of Pavia, Pavia, Italy.

Background: The pathophysiology of abdominal distention in irritable bowel syndrome (IBS) is still a matter of debate, but the relationship between modifications of intestinal tone and abdominal volume has never been analyzed.

Methods: Eighty-four patients affected by IBS and reporting moderate to severe abdominal distention were enrolled. Thirty-nine presented abdominal distention immediately after and forty-five presented abdominal distention independently of meal intake.

Tie2 Expressing Monocytes in the Spleen of Patients with Primary Myelofibrosis.

PLoS One

July 2017

Biotechnology Research Area, IRCCS Policlinico S. Matteo Foundation, Pavia, Italy.

Primary myelofibrosis (PMF) is a Philadelphia-negative (Ph-) myeloproliferative disorder, showing abnormal CD34+ progenitor cell trafficking, splenomegaly, marrow fibrosis leading to extensive extramedullary haematopoiesis, and abnormal neoangiogenesis in either the bone marrow or the spleen. Monocytes expressing the angiopoietin-2 receptor (Tie2) have been shown to support abnormal angiogenic processes in solid tumors through a paracrine action that takes place in proximity to the vessels. In this study we investigated the frequency of Tie2 expressing monocytes in the spleen tissue samples of patients with PMF, and healthy subjects (CTRLs), and evaluated their possible role in favouring spleen angiogenesis.

Pancreatic ductal adenocarcinoma is characterized by a poor prognosis and a low median survival, despite improvements observed for many other solid tumours. Intensive research efforts have been undertaken during the last decades to discover new prognostic and treatment predictive biomarkers for pancreatic ductal adenocarcinoma. The mainstay of medical treatment for the disease has been the well-tolerated nucleoside analogue, gemcitabine.

Objectives: Little information is available on the mechanisms responsible for dyspeptic symptoms in postprandial distress syndrome (PDS), characterized by the presence of prevalently meal-related early satiation and fullness, and the epigastric pain syndrome (EPS), characterized by the prominent symptom of epigastric pain, generally not meal related. In a group of PDS patients, the presence of hypersensitivity to gastric distension in both fasting and postprandial phases was described as the main pathophysiological mechanism; on the contrary, we have no information on the pathophysiology of EPS.

Methods: Sixty Helicobacter pylori (HP)-negative, irritable bowel syndrome (IBS)-negative, and gastroesophageal reflux disease (GERD)-negative patients with functional dyspepsia according to Rome III criteria underwent symptom, anxiety, depression, and somatization evaluation, gastric barostat test, and gastric emptying time evaluation for solids.

Hydrogen breath test and intestinal gas production.

Eur Rev Med Pharmacol Sci

April 2015

1st Department of Internal Medicine, University of Pavia, IRCCS S. Matteo Hospital Foundation, Pavia, Italy.

Despite extensive use in clinical practice, difficulties regarding interpretation of hydrogen breath test are still very frequent, even on research grounds. After the administration of a non-absorbable sugar, such as lactulose, an increase of breath hydrogen and methane is evident; this phenomenon is considered an index of colonic fermentation. It is not clear, however, if the levels of these compounds correlate with the presence and severity of functional symptoms, nor if they accurately reflect gas production at colonic level.

Osteoporosis affects many patients with celiac disease (CD), representing the consequence of calcium malabsorption and persistent activation of mucosal inflammation. A slight increase of fracture risk is evident in this condition, particularly in those with overt malabsorption and in postmenopausal state. The adoption of a correct gluten-free diet (GFD) improves bone derangement, but is not able to normalize bone mass in all the patients.

Extrahepatic textiloma long misdiagnosed as calcified echinococcal cyst.

Case Rep Gastrointest Med

March 2013

Division of Infectious and Tropical Diseases, University of Pavia, IRCCS S. Matteo Hospital Foundation, WHO Collaborating Center for Clinical Management of Cystic Echinococcosis, 27100 Pavia, Italy.

Textiloma or gossypiboma is a retained surgical swab in the body after an operation and is a complication that can remain undetected for many years and may represent a diagnostic dilemma depending on its location. It may be confused with several focal lesions and an accurate history taking, combined with clinical and instrumental data, is key to suspecting the diagnosis. We report a case of abdominal textiloma that was initially misdiagnosed as echinococcal cyst and discuss the differential diagnosis based on sonographic features and the WHO-IWGE classification.

Expert consensus for the diagnosis and treatment of cystic and alveolar echinococcosis in humans.

Acta Trop

April 2010

Division of Infectious and Tropical Diseases, University of Pavia, IRCCS S.Matteo Hospital Foundation, WHO Collaborating Center for Clinical Management of Cystic Echinococcosis, 27100 Pavia, Italy.

The earlier recommendations of the WHO-Informal Working Group on Echinococcosis (WHO-IWGE) for the treatment of human echinococcosis have had considerable impact in different settings worldwide, but the last major revision was published more than 10 years ago. Advances in classification and treatment of echinococcosis prompted experts from different continents to review the current literature, discuss recent achievements and provide a consensus on diagnosis, treatment and follow-up. Among the recognized species, two are of medical importance -Echinococcus granulosus and Echinococcus multilocularis - causing cystic echinococcosis (CE) and alveolar echinococcosis (AE), respectively.
