However, a healthy GFD is more complex than the only exclusion of gluten-containing foods. Most celiac patients do not receive nutritional advice and tend to consume industrial gluten-free products (GFPs), which often lack fiber, vitamins, and other micronutrients while being rich in saturated fats and refined sugars. This review focuses on the main potential metabolic disorders and nutritional deficiencies in CD patients at diagnosis and dissects the main nutritional and metabolic issues due to a non-balanced GFD. Nutritional tips to achieve an adequate dietary approach in CD are provided. We also compared the main nutritional components of naturally gluten-free cereals (including pseudocereals) to give an exhaustive overview of the possible healthy alternatives to processed GFPs. Clinicians and dietitians should be systematically involved in the diagnosis of CD to monitor the appropriateness of GFD a...

This narrative review will focus on several aspects of sepsis in the context of Alcohol-related Liver Disease. The pathophysiology of the increased susceptibility to infections consists mainly of impaired innate and adaptive immunity, changes in gut microbiota with consequent gut translocation of bacteria due to both alcohol abuse and the underlying liver disease. The diagnosis of sepsis in the context of Alcohol-related Liver Disease is challenging. Moreover, the use of classical acute-phase serum proteins (e.g., C-reactive protein and procalcitonin) has several limitations in this setting. The early administration of an adequate antibiotic treatment is pivotal. Finally, measures of infection control and prevention are needed because the prognosis of sepsis in patients affected by Alcohol-related Liver Disease is poor.

This paper is part of a series of articles written during the difficult period of the ongoing global pandemic and published all together in this fourth issue of the Italian Journal of Medicine, with the aim of sharing the direct experiences of those who were the first to face this severe emergency, expressing each point of view in the management of COVID-19 in relation to other diseases. Each article is therefore the result of many efforts and a joint collaboration between many colleagues from the Departments of Internal Medicine or Emergency Medicine of several Italian hospitals, engaged in the front line during the pandemic. These preliminary studies therefore cover diagnostic tools available to health care personnel, epidemiological reflections, possible new therapeutic approaches, disc...

Therefore, the CD patients could be exposed to an increased risk of contracting SARS-CoV-2, a virus for which the WHO declared a pandemic status in March 2020. This study aims to investigate the incidence of SARS-CoV-2 infection in CD patients, to assess the impact of CD on the risk of contracting this virus. PATIENTS AND METHODS This retrospective multicentric cohort study evaluated 542 celiac patients, who answered a questionnaire concerning both the underlying disease (adherence to the gluten-free diet, residual symptoms) and the possible SARS-CoV-2 infection (swab outcome, presence and characteristics of symptoms and type of treatment received), referring to the period between 20th January 2020 and 27th October 2020. RESULTS Five patients (0.92%) tested positive; of these, 2 were asymptomatic and 3 developed symptoms of COVID-19. The incidence of ...

It often affects men with a history of alcohol abuse. Here we report a review of the literature about this disease together with the description of a patient affected by Madelung's disease and acute alcoholic hepatitis.

Liver transplantation (LT) could represent a risk factor for the onset of WE in AUD patients, due to the onset of chronic depletion of thiamine in this population and the high metabolic demand of surgery and the postoperative period. However, few data are available about the risk of the onset of WE in AUD patients after LT. Here we report three cases of AUD patients who developed WE with confusion and delirium after LT. Prompt parenteral administration of thiamine led to a rapid improvement of the clinical condition and a complete remission of neurological symptoms after 3–4 days. In addition, a search of the available English literature was conducted in order to perform a review of the possible association between the onset of WE and LT in AUD patients. A prophylactic treatment regimen based on the administration of thiamine cou...

The goal of this study was to describe the impact of a multidisciplinary treatment program on alcohol consumption and social reintegration in individuals with AUD experiencing homelessness. Methods Thirty-one individuals with AUD experiencing homelessness were admitted to an inpatient unit for 5–6 days for clinical evaluation and to treat potential alcohol withdrawal syndrome. A group of volunteers, in collaboration with the Community of Sant’Egidio, provided social support aimed to reintegrate patients. After inpatient discharge, all patients were followed as outpatients. Alcohol intake (number drinks/day), craving and clinical evaluation were assessed at each outpatient visit. Biological markers of alcohol use were evaluated at enrollment (T0), at 6 months (T1) and 12 months (T2). Results Compared with T0, patients at T1 showed a significant reduction in alcohol consumpt...

Preclinical and human studies suggest that baclofen, a GABA B receptor agonist, might be a novel treatment for patients with moderate to severe AUD. 6 Notably, a few years after initial randomized clinical trials (RCTs) were conducted, the potential use of this medication for AUD dramatically increased in its popularity due to a French case report describing the use of very high doses of baclofen to treat alcohol craving and drinking. 7 This intriguing yet purely anecdotical case report led to significant scientific and mass media attention and to the use of baclofen (off-label) in the treatment of AUD, such that the French drugs regulatory agency became involved in evaluating the use of baclofen in AUD. However, clinical studies conducted in Europe, USA, Australia, Israel and that evaluated baclofen efficacy in AUD have yielded conflicting results with some but not all RCTs showing an effect of baclofen. 6 The three recent meta-analyses do not draw definitive conclusions on the efficacy of baclofen in the treatment of AUD. 8-10 In fact, one meta-analysis 8 found no significant superiority of baclofen over placebo on the outcomes of each study whereas the other two found that baclofen treatment significantly increased the rate of abstinent patients 9-10 and time to first lapse 9 compared to placebo. Furthermore, one meta-analysis found larger effect sizes of baclofen among heavy drinkers and studies using lower doses. 9 The other study found no significant efficacy of baclofen in reducing the severity of craving for alcohol, anxiety, and depression. 10 In addition, these two meta-analyses reported no significant efficacy of baclofen on other important outcomes such as rate of abstinence days 9-10 or rate of heavy drinking days. 10 Chiefly, all three meta-analyses found overall a small effect size and substantial heterogeneity among studies. 8-10 Following the publication of these metaanalyses, 8-10 a further RCT has been completed and data analysis is currently under way (JC Garbutt, unpublished; ClinicalTrials.gov: NCT01980706). Despite the lack of consistent evidence of efficacy, baclofen is frequently used off-label to treat AUD, especially in some European countries and Australia. However, there is significant variability in the use of baclofen for clinical research and in medical practice, due to differences in treatment provision for AUD, clinical experience, and country-specific regulations and culture. This Consensus Statement was developed by an international group of experts in the use of baclofen for AUD, based on the current evidence from clinical practice and research of baclofen in patients with moderate to severe AUD (see Panel). Most members of the Consensus had a meeting on May 25 th , 2018 in Cagliari, Italy, at the GABA B Receptor Conference, in a post-conference closed session. To develop the Consensus Statement,

This single-site survey aimed at assessing perceived stress and risk to develop burnout syndrome among physicians operating in COVID wards. Methods: This longitudinal survey evaluated stress and burnout in 51 physicians operating in the COVID team of Gemelli Hospital, Italy. Participants were asked to complete the Maslach Burnout Inventory (MBI) and the Perceived Stress Questionnaire on a short run (PSQs) (referring to the past 7 days) at baseline (T0) and then for four weeks (T1-T4). Perceived Stress Questionnaire on a long run (PSQl) (referring to the past 2 years) was completed only at T0. Results: Compared with physicians board-certified in internal medicine, those boardcertified in other disciplines showed higher scores for the Emotional Exhaustion (EE) score of the MBI scale (P < .001). Depersonalisation (DP) score showed a reduction over time (P = .002). Attending physicians scored lower than the resident physicians on the DP scale (P = .048) and higher than resident physicians on the Personal Accomplishment (PA) scale (P = .04). PSQl predicted higher scores on the EE scale (P = .003), DP scale (P = .003) and lower scores on the PA scale (P < .001). PSQs showed a reduction over time (P = .03). Attending physicians had a lower PSQs score compared with the resident physicians (P = .04).
