For contrast-enhanced CT examinations, there is a lack of comprehensive optimal management strategies of risk factors to reduce the risk of iodinated contrast media (ICM)-induced acute adverse reactions (AAR). Here, we determine the relationship between the rate of ICM-AAR and a stratified assessment and warning (SAW) regimen, which integrated risk identification, stratification, early warning, and prevention. A total of 120,822 cases in the conventional assessment period (58 years ± 15, 55...

Since the advent of computed tomography (CT), iodinated contract media (ICM) has become one of the most regularly administered intravenous medications in clinical settings. Although considered generally safe, ICM is one of the most common causes of adverse drug reactions in clinical practice, accounting for more than two million adverse reactions worldwide. Currently, there are few useful tools to diagnose patient hypersensitivity, with the major limitation being the lack of consensus regarding the mechanisms of hypersensitivity to ICM...

The efficacy and adverse reaction (AR) of the three groups are observed during 12 months of treatment and after drug withdrawal, and the clinical efficacy and safety of the three treatment methods are evaluated...

Medical imaging is required for a complete clinical evaluation to identify lung involvement or pulmonary embolism during SARS-CoV-2 infection or pulmonary and cardiovascular sequelae. Contrast media (CM) have undoubtedly been useful in clinical practice due to their ability to improve medical imaging in COVID-19 patients. Considering their important use, especially in hospitalized COVID-19 patients, and that increased use of a medical tool could also be associated with its deeper knowledge, we chose to explore if new information emerged regarding CM safety profiles...

In order to explore more ideal intravenous anesthesia drug in clinical practice, the analgesic effect of remazolam combined with etomidate in painless gastroenteroscopy and its effect on stress response is investigated. A total of 100 patients are selected for the gastric disease screening, and they are randomly divided into the single-drug group and composite group, with 50 cases in each group. Etomidate, mazzolone, and etomidate are used to anesthetize the patients, and then, the effects of different solutions on analgesia, sedation, and stress response are compared and analyzed, and the adverse reactions are improved...

INTRODUCTION: The recurrence rates of immediate adverse drug reactions (ADRs) to the alternative radiocontrast media (RCM) are not well known. Previous studies suggest selection of alternative RCM considering carbamoyl side chains; however, its usefulness for preventing the recurrence of ADRs has not been clearly verified. OBJECTIVE: The aim of this study was to verify the recurrence rate of immediate ADRs according to the alternative RCM. METHOD: This retrospective study analyzed 6420 contrast-enhanced computed tomography (CT) cases of 2009 patients registered in the ADR system from 861,664 CT cases in a single tertiary hospital between 2015 and 2020...

Background: Western drugs effectively manage persistent depressive disorder (PDD) but are associated with side effects. Objective: To observe the efficacy and safety of modified Xiaochaihu Decoction combined with mirtazapine in treating PDD. Methods: Patients with PDD were enrolled at the Naval General Hospital (06/2018-02/2019) and randomized to modified Xiaochaihu Decoction and modified Xiaochaihu Decoction with mirtazapine. The self-rating depression scale (SDS) and traditional Chinese medicine (TCM) scale were assessed at baseline and after 12 weeks...

Iodinated- (ICM) and gadolinium-based (GCM) contrast media are used in radiology imaging techniques, such as computer tomography (CT) and magnetic resonance (MR), respectively. The paper aims to analyze the adverse drug reactions of ICM and GCM on different sites of the body in a highly polluted environment. We analyzed the pharmacovigilance in contrast media on the basis of reports submitted to the Regional Center for Monitoring of Adverse Drug Reactions (ADR) at the Department of Clinical Pharmacology in Wrocław...

At present, iodinated contrast media (ICM) are mostly non-ionic, have low osmolality, and are safe. Even if adverse drug reactions (ADRs) occur, most are chemo-toxic symptoms and require only observation or H1 antihistamines. However, rare, unpredictable, and even life-threatening hypersensitivity can still occur. The aim of this review is to summarize the issues that all relevant staff need to know about and be able to respond to. The most significant risk factor for ICM hypersensitivity is a history of ICM hypersensitivity...

BACKGROUND: The epidemiology of drug-induced anaphylaxis (AN) using the Japanese nationwide database has not been reported, even though drugs are a common trigger of AN. OBJECTIVE: This study aimed to describe the epidemiological profile of drug-induced AN, including fatal cases, using the Japanese Adverse Drug Event Report database (JADER). METHODS: We extracted data regarding drug-induced adverse events between April 2004 and February 2018 published in JADER by the Pharmaceuticals and Medical Devices Agency...

In evaluating adverse drug reactions (ADRs), patch tests (PTs), skin prick tests (SPTs), and intradermal tests (IDTs) are useful tools for identifying responsible drugs and finding safe alternatives. Their diagnostic value depends on the clinical features of the ADR and on the drug tested. PTs have a good sensitivity in assessing acute generalized exanthematous pustulosis and drug rash with eosinophilia and systemic symptoms. SPTs done with all drugs except opiates are used for immediate hypersensitivity reactions...
