Hypersensitivity reactions to proton pump inhibitors. An EAACI position paper.

Proton pump inhibitors (PPIs) are invaluable therapeutic options in a variety of dyspeptic diseases. In addition to their well-known risk profile, PPI consumption is related to food and environmental allergies, dysbiosis, osteoporosis, as well as immediate and delayed hypersensitivity reactions (HSRs). The latter, although a rare event, around 1%-3%, due to the extraordinarily high rate of prescription and consumption of PPIs are related to a substantial risk.

A practical guide to address reactions to vaccines in children.

Currently available vaccines are safe, but, potentially, any vaccine can cause an allergic reaction and, albeit very rare, anaphylaxis can occur. Although its rarity, the precise diagnostic management of a suspected anaphylaxis postvaccination is of paramount importance due to the risk of a potentially serious reaction after re-exposure, while a misdiagnosis might lead to an increase in the number of children that interrupt vaccinations resulting in an unjustifiably individual and collective risk of loss of protection against immune preventable diseases. In the light that most cases of suspected allergy to a vaccine are not effectively confirmed in up to 85% of the cases referred for an allergy evaluation, patients can continue the vaccination schedule with the same formulation and tolerance of the booster doses.

Diagnosis and treatment of chronic synovitis in patients with haemophilia: consensus statements from the Italian Association of Haemophilia Centres.

Although synovitis is recognized as a marker of joint disease activity, its periodic assessment is not included in routine clinical surveillance of patients with haemophilia (PwH). In order to evaluate the current knowledge and to identify controversial issues, a preliminary literature search by the Musculoskeletal Committee of the Italian Association of Haemophilia Centres (AICE) has been conducted. Statements have been established and sent to the Italian AICE members to collect their level of agreement or disagreement by a Delphi process.

Depth of Intestinal Wall Infiltration and Clinical Presentation of Deep Infiltrating Endometriosis: Evaluation of 553 Consecutive Cases.

Introduction: Intestinal involvement in endometriosis was first described by Sampson in 1922. The reported incidence ranges between 3% and 37% in patients diagnosed with endometriosis. In literature, there are few studies that correlate the severity of endometriosis (in terms of intestinal infiltration) and its clinical presentation.

Use of NeuroEyeCoach™ to Improve Eye Movement Efficacy in Patients with Homonymous Visual Field Loss.

Visual field deficits are common in patients with damaged retinogeniculostriate pathways. The patient's eye movements are often affected leading to inefficient visual search. Systematic eye movement training also called compensatory therapy is needed to allow patients to develop effective coping strategies.

Assessment and treatment of severe pancreatitis. Protease inhibitor.

From the theoretical point of view, antiproteolytic therapy would seem to be the rationale for acute pancreatitis management. Unfortunately, clinical human trials studying the role of antiproteases in the treatment of acute pancreatitis differ in several respects in terms of their basic design. As a consequence, any form of homogeneous analysis of the reported data as a whole is impossible.

Surgical treatment of pancreatic metastases from renal cell carcinomas.

Pancreatic metastases from a renal cell carcinoma are rare and may occur long after manifestation of the primary disease. Resection of the metastases should be regarded as the best treatment. In our center, owing to the slow evolution of these secondaries, we perform resections capable of limiting the destruction of the pancreatic parenchyma as far as possible.

Controlled clinical trial of pefloxacin versus imipenem in severe acute pancreatitis.

Background & Aims: Antibiotic prophylaxis in severe pancreatitis has recently yielded promising clinical results, with imipenem significantly reducing the incidence of infected necrosis compared with an untreated control group. On the bases of pefloxacin's spectrum of action and pancreatic penetration, we investigated whether such drugs represent a valid alternative to imipenem.

Methods: In a multicenter study, 60 patients with severe acute pancreatitis with necrosis affecting at least 50% of the pancreas were randomly allocated to receive intravenous treatment for 2 weeks with pefloxacin, 400 mg twice daily (30 patients), or imipenem, 500 mg three times daily (30 patients), within 120 hours of onset of symptoms.

Pancreatic cystic manifestations in von Hippel-Lindau disease.

Conclusion: In view of the frequent absence of symptoms related to pancreatic lesions, screening tests for VHL should always include assessment of the pancreas and, considering the frequency of polycystic manifestations, VHL should always be borne in mind in the differential diagnosis of multiple pancreatic cysts, especially when occurring in young patients and in the absence of a positive history of pancreatic disease.

Background: Von Hippel-Lindau disease (VHL) is a hereditary disease transmitted with an autosomal dominant character and characterized by hemangioblastomas of the central nervous system and retina, renal tumors and cysts, and pheochromocytoma. Pancreatic manifestations of VHL are reported in the literature with incidences ranging from 16 to 29% of cases and consist mainly in cystadenomas of the serous type and in multiple cystic lesions, often with complete replacement of the gland.

Gabexate mesilate in the treatment of acute pancreatitis.

Despite controversial experimental and clinical findings, the use of Aprotinin (A) in the treatment of acute pancreatitis (AP) is still widespread in our country. Compared to A, Gabexate Mesilate (FOY) should have the following advantages: lack of antigenicity, low molecular weight with better cellular penetrance, wide inhibitory spectrum (against phospholipase A2 too) and good tolerability. In order to verify the efficacy of FOY versus, we decided to carry out a prospective multicenter (34 centers) randomized double blind trial in moderate-severe AP with FOY 3g/day versus A 1,500,000 U.

Effectiveness of 5-aminosalicylic acid for maintaining remission in patients with Crohn's disease: a meta-analysis.

Objectives: We conducted a meta-analysis of the published randomized clinical trials to evaluate the effectiveness of 5-aminosalicylic acid (5-ASA) for maintaining remission in inactive Crohn's disease.

Methods: The trials were identified by standard computerized techniques for literature search. All studies included in the meta-analysis were aimed at evaluating the effectiveness of 5-ASA in comparison with a control group receiving either no treatment or placebo.

Pharmacokinetics of amikacin in neonates.

Only a few data have thus far been published on the pharmacokinetics of amikacin in neonates. To gain further information on this issue, we studied a series of 32 neonates who were treated with amikacin for suspected or documented bacterial infection. Nineteen neonates were preterm (mean gestational age = 32.

PKRD: a pharmacokinetic program for least-squares and bayesian analysis of repeated-dose pharmacokinetic curves.

A microcomputer program is presented which analyses multiple-dose pharmacokinetic curves using either a least-squares nonlinear analysis or a bayesian fit. The least-squares subroutine is designed to fit retrospective pharmacokinetic curves and can generate the so-called population pharmacokinetic parameters using the Standard Two-Stage method. The bayesian subroutine can instead be used prospectively to individualise the dosage regimen of a patient based on the concentrations measured in the initial phases of the drug treatment.
