Celiac disease: experience of general practitioners in Brianza Area- Monza- Milan-Italy.

Aim: The purpose of the study was to better investigate the degree of knowledge and the diagnostic approach concerning celiac disease and its extra-intestinal manifestations by general practitioners in Italy. Background: Celiac Disease is a common chronic disease, but often goes undiagnosed because of atypical symptoms or silent disease. Currently there are non-definitive data about the disease management approach concerning celiac disease by general practitioners. Methods: To better investigate the degree of knowledge and the diagnostic approach concerning celiac disease and its extra-intestinal manifestations, questionnaire was used to assess the daily practice of diagnosis, treatment, and follow-up of this condition by general practitioners in two densely populated area in Italy: Monza-Brianza Area and Milan City. The questionnaire was composed of 18 questions that explored 3 precise domains: diagnosis criteria, correct management of celiac disease and availability for training. The frequencies of the domains explored were analyzed, analyzes were carried out to identify differences between the groups of general practitioners interviewed. Results: Analysis of the questionnaires showed a degree of knowledge and preparation comparable to that of other countries, even though not sufficient to guarantee access to early diagnosis for all patients with celiac disease. The knowledge was not influenced by the years of experience or specific curriculum of health professionals. General practitioners under 40 were much more in favor of continuous training and were aware of its importance (OR=10.55; CI95%: 1.62-445.39), although this need was a high priority in the whole group interviewed (84.7%). Conclusion: Continuous specific training aimed at primary care physicians and general practitioners is the first tool to improve early diagnosis. A second opportunity is represented by the continuous dialogue between general practitioners and tertiary level hospitals and universities.

Approaches for Selective Vaccinations in Cirrhotic Patients.

Bacterial and viral infections are common in cirrhotic patients, and their occurrence is associated with the severity of liver disease. Bacterial infection may increase the probability of death by 3.75 times in patients with decompensated cirrhosis, with ranges of 30% at 1 month and 63% at 1 year after infection. We illustrate the indications and the modalities for vaccinating cirrhotic patients. This topic is important for general practitioners and specialists.

Effectiveness of basal LH in monitoring central precocious puberty treatment in girls.

OBJECTIVES: Treatment of central precocious puberty (CPP) is based on administration of GnRH agonists in order to suppress hypothalamic-pituitary-gonadal axis and thus induce the stabilization or regression of pubertal development. Our aim was to determine whether the single basal serum LH and/or FSH concentration could be an effective tool to assess the efficacy of treatment to suppress activation of hypothalamic-pituitary axis. PATIENTS AND METHODS: Serum LH and FSH were measured before and after the GnRH injection, as well as E2 basal levels in 60 girls with documented idiopathic CPP at diagnosis and 18 and 30 months after the beginning of therapy. RESULTS: At diagnosis, peaks of >5 IU/L of LH and of FSH were observed in 100 and 91.6% of girls, respectively, with basal LH values of <1 IU/L in 70% and basal FSH levels of <1 IU/L in 10%. E2 were <20 pg/mL in 36.6%. After 18 months, a suppressed peak (i.e. <3 IU/L) was recorded in 85% of girls (p<0.01) for LH and in 98.3% for FSH (p<0.01). Basal LH <1 IU/L was detected in 85% (p<0.01) and basal FSH ≤1 IU/L in 40% (p<0.01). Serum E2 ≤20 pg/mL was recorded in 61.6% (p<0.01). After 30 months, all patients showed LH suppressed peak (p<0.01) and 98.3% suppressed FSH peak (p<0.01). 100% showed basal LH concentrations <1 IU/L (p<0.01) and 38.3% FSH basal values <1 UI/mL (p<0.01). E2 ≤20 pg/mL was observed in 32.72% (p=NS). CONCLUSIONS: Basal LH values are a reliable indicator of the efficacy of GnRHa therapy after 30 months of GnRHa therapy.

COVID emergency: an opportunity to increase the interaction between hepatologist and primary care physician.

The outbreak of Coronavirus disease 2019 (COVID-19) worldwide had evidenced the opportunity to increase the interaction between specialist and primary care physician (PCP). COVID 19, started in December 2019 in China, has been considered a public health emergency by the Department of Health and Human Services and, now, it is a pandemic disease with worldwide diffusion. The COVID-19 crisis permits to increase the role of telemedicine as a tool for the delivery of health care services at distance and to slow down the virus diffusion. This technology is cheap and easy to use but it is limited by governmental licensing restrictions, reimbursement barriers, lesser extent of infrastructure and difficulties related to the change. During COVID-19 epidemy, telemedicine is safe, low cost and-permits to treat urgent and routine specialist cases without human proximity and contact which would spread infection, particularly to the elderly and immunocompromised patients. In COVID-19 era, the goal of PCP is to reduce travels and visits in specialized center for liver disease patients. A strict collaboration between specialized hepatologist and PCP is needed.

Pneumococcal vaccination in celiac disease.

INTRODUCTION: Celiac disease (CD) is an immune-mediated disorder associated with gluten exposure in genetically predisposed subjects. Areas covered: Infectious disease is one of the causes of morbidity and mortality in CD patients. Invasive streptococcus pneumoniae (pneumococcus) is a particularly dangerous morbid condition in both the general population and celiac patients. Pneumococcal vaccination is the most effective means for its prevention. Expert opinion: In CD, evaluation of spleen function should be useful to select patients who may benefit from vaccination to reduce the risk of pneumococcal disease. Different strategies could be employed: physicians could search for signs of hyposplenism on peripheral blood smear or abdominal ultrasound. However, the best strategy to identify which patients will benefit from pneumococcal vaccination has not yet been defined.

Common features of patients with autoimmune atrophic gastritis.

BACKGROUND & AIMS: Autoimmune atrophic gastritis (AIG) is characterized by immune-mediated chronic inflammation of the gastric body and fundus, leading to hypo-achlorhydria and vitamin B12 deficiency. We analyzed the clinical features of AIG and sought to identify factors that might be used in diagnosis. METHODS: We collected and analyzed clinical data from 99 consecutive patients (age, 59 ± 17 y) who were diagnosed with AIG, based on histologic factors and the presence of autoantibodies against gastric parietal cells. RESULTS: Clinical factors that led to a diagnosis of AIG included hematologic findings related to vitamin B12 deficiency (n = 37), incidental histologic evidence in gastric biopsy specimens (n = 34), immune disorders (n = 18; 9 were celiac disease), neurologic symptoms (n = 6), and a family history of AIG (n = 4). CONCLUSIONS: Based on an analysis of 99 consecutive patients with AIG, this disorder is not solely a condition of the elderly. Other features to look for in making a diagnosis of AIG include vitamin B12 deficiency, histologic factors, and immune disorders.

Mycobacterium avium paratuberculosis in Italy: commensal or emerging human pathogen?

BACKGROUND: Specific bacterial infections or alterations of the gut microbiota likely trigger immuno-pathological phenomena associated with Crohn's disease and ulcerative colitis. Mycobacterium avium subspecies paratuberculosis is a candidate etiological agent of Crohn's disease. Definitive causal connection between Mycobacterium avium subspecies paratuberculosis infection and Crohn's disease has not been demonstrated. AIMS: To determine the circulation of Mycobacterium avium subspecies paratuberculosis in Crohn's disease patients and water supplies in an Italian region where this bacterium is endemic in cattle farms. METHODS: Mycobacterium avium subspecies paratuberculosis screening was performed on biopsies from human patients, and from water samples, using two different PCR procedures. RESULTS: In hospitals where multiple specimens were obtained from different sites in the intestine, the prevalence of Mycobacterium avium subspecies paratuberculosis infection was 82.1% and 40% respectively in Crohn's disease and ulcerative colitis patients; in another hospital, where single specimens were obtained from patients, the bacterium was not detected. Control subjects also harboured Mycobacterium avium subspecies paratuberculosis, but at a lower prevalence. Tap water samples collected in the study area contained Mycobacterium avium subspecies paratuberculosis DNA. DISCUSSION: The results of screenings for Mycobacterium avium subspecies paratuberculosis in humans are deeply influenced by both the number and location of the collected biopsies. There is a wide circulation of the organism in the study area, considering the prevalence in humans and its presence in drinking water.

Effect of aliskiren addition to amlodipine on ankle edema in hypertensive patients: a three-way crossover study.

OBJECTIVE: The aim of this study was to assess the effect of aliskiren and amlopidine on ankle-foot volume (AFV) and pretibial subcutaneous tissue pressure (PSTP). RESEARCH DESIGN AND METHODS: After 4-week placebo, 120 outpatients with grade 1 - 2 hypertension were randomized to amlodipine 10 mg or aliskiren 300 mg or their combination for 8 weeks in three crossover periods. At the end of each treatment, blood pressure, AFV, PSTP, plasma renin activity (PRA) and norepinephrine were assessed. RESULTS: Both monotherapies similarly reduced systolic blood pressure (SBP; p < 0.001) and diastolic blood pressure (DBP; p < 0.001), but the reduction was greater with amlodipine/aliskiren combination (SBP: - 24.6 mmHg, p < 0.001 vs monotherapy; DBP: -20.9 mmHg, p < 0.01 vs monotherapy). Amlodipine increased both AFV (+ 28.4%, p < 0.01) and PSTP (+ 80.4%, p < 0.01), while the combination produced a less marked increase in AFV (+ 6.6%, p < 0.01 vs amlodipine) and PSTP (+ 20.1%, p < 0.01 vs amlodipine). Plasma norepinephrine increased with amlodipine (+ 53.5%, p < 0.01) and this increase was not reduced by aliskiren addition. PRA was unaffected by amlodipine, while it was reduced by both aliskiren monotherapy (- 77.7%, p < 0.01) and aliskiren/amlodipine combination (- 75.7%, p < 0.01). CONCLUSIONS: Direct renin inhibition by aliskiren partially counteracts the microcirculatory changes responsible for calcium-channel-induced edema formation, possibly through preferential vasodilation of venous capacitance vessels.
