BACKGROUND: Measurement of disease activity guides treatment of chronic spontaneous urticaria (CSU). A weekly Urticaria Activity Score-here, the average of twice-daily patient assessment of itch and hives scores summed over 1 week (UAS7TD )-measures severity from 0 to 42. Insufficient evidence exists whether disease activity states, defined by categorical UAS7TD scores, correlate with other patient-reported outcomes and treatment response. OBJECTIVE: To evaluate and compare categorical UAS7TD scores with selected measures of disease-related quality of life and impact...

Chelsey Edmonds, Michael Swanoski
Geriatric patients often experience insomnia because of physiological and neurological changes that occur during the aging process. Use of benzodiazepines, nonbenzodiazepine hypnotics, and diphenhydramine for the treatment of insomnia pose an increased risk of cognitive impairment, falls, and fractures in this patient population. Therapeutic alternatives approved by the Food and Drug Administration include suvorexant, doxepin, ramelteon, and tasimelteon, which have shown efficacy and safety in various studies...

Drug-induced liver injury (DILI) is the most common cause of acute liver failure in the Unites States and accounts for 10% of acute hepatitis cases. We report the only known case of diphenhydramine-induced acute liver injury in the absence of concomitant medications. A 28-year-old man with history of 13/14-chromosomal translocation presented with fevers, vomiting, and jaundice. Aspartate-aminotransferase and alanine-aminotransferase levels peaked above 20,000 IU/L and 5,000 IU/L, respectively. He developed coagulopathy but without altered mental status...

Various biological factors have been implicated in convulsive seizures, involving side effects of drugs. For the preclinical safety assessment of drug development, it is difficult to predict seizure-inducing side effects. Here, we introduced a machine learning-based in vitro system designed to detect seizure-inducing side effects. We recorded local field potentials from the CA1 alveus in acute mouse neocortico-hippocampal slices, while 14 drugs were bath-perfused at 5 different concentrations each. For each experimental condition, we collected seizure-like neuronal activity and merged their waveforms as one graphic image, which was further converted into a feature vector using Caffe, an open framework for deep learning...

Elotuzumab, an immunostimulatory SLAMF7-targeting monoclonal antibody, induces myeloma cell death with minimal effects on normal tissue. In a previous phase 3 study in patients with relapsed/refractory multiple myeloma (RRMM), elotuzumab (10 mg/kg, ∼3-hour infusion), combined with lenalidomide and dexamethasone, demonstrated durable efficacy and acceptable safety; 10% (33/321) of patients had infusion reactions (IRs; Grade 1/2: 29; Grade 3: 4). This phase 2 study (NCT02159365) investigated an accelerated infusion schedule in 70 patients with newly diagnosed multiple myeloma or RRMM...

Significant histamine H1 receptor occupation in the central nervous system (CNS) is associated with sedation. Here we examined the time profiles of the H1 receptor occupancy (RO) in the CNS using sedative (diphenhydramine and ketotifen) and non-sedative (bepotastine and olopatadine) antagonists at their therapeutic doses by integrating in vitro and animal data. A pharmacokinetic model was constructed to associate plasma concentrations and receptor binding in the brain. Dissociation and association rate constants with the H1 receptor and plasma and brain unbound fractions were determined in vitro...

BACKGROUND AND AIMS: Current guidelines recommend diphenhydramine in patients undergoing endoscopy who are not adequately sedated with a benzodiazepine and opioid combination. Because this practice has not been adequately assessed, we performed a randomized, double-blind trial comparing diphenhydramine with continued midazolam in such patients. METHODS: Patients undergoing elective colonoscopy with moderate sedation were eligible. Sedation was measured with the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score with adequate sedation defined as 3 on a 0- to 5-point scale...

The purpose of the study was to evaluate suppression of the bitterness intensity of bitter basic drugs by chlorogenic acid (CGA) using the artificial taste sensor and human gustatory sensation testing and to investigate the mechanism underlying bitterness suppression using (1)H-NMR. Diphenhydramine hydrocholoride (DPH) was the bitter basic drug used in the study. Quinic acid (QNA) and caffeic acid (CFA) together form CGA. Although all three acids suppressed the bitterness intensity of DPH in a dose-dependent manner as determined by the taste sensor and in gustatory sensation tests, CFA was less effective than either CGA or QNA...

The purpose of this study was to evaluate the taste-masking effects of chlorogenic acid (CGA) on bitter drugs using taste sensor measurements and surface plasmon resonance (SPR) analysis of CGA-drug interactions. Six different bitter drugs were used: amlodipine besylate (AMD), diphenhydramine hydrochloride (DPH), donepezil hydrochloride (DNP), rebamipide (RBM), diclofenac sodium (DCF) and etodolac (ETD). Taste sensor outputs were significantly inhibited by the addition of CGA to all drugs. The inhibition ratio of the taste sensor output decreased in the following order DPH>DNP>AMD≈DCF≈RBM≈ETD...

Jiwon Kim, Jin-Ho Song
Microglial NADPH oxidase is a major source of toxic reactive oxygen species produced during chronic neuroinflammation. Voltage-gated proton channel (HV1) functions to maintain the intense activity of NADPH oxidase, and channel inhibition alleviates the pathology of neurodegenerative diseases such as ischemic stroke and multiple sclerosis associated with oxidative neuroinflammation. Antagonists of histamine H1 receptors have beneficial effects against microglia-mediated oxidative stress and neurotoxicity. We examined the effects of the H1 antihistamines, diphenhydramine and chlorpheniramine, on proton currents in BV2 microglial cells recorded using the whole-cell patch clamp technique...

Coughing in a child induced by upper respiratory tract infections (URTIs) can be a problem, both for the child and its parents. Current studies show a lack of proven efficacy for over-the counter (OTC) medications, but promising data support the use of honey for children. The aim of this study was to compare the effects of two kinds of Iranian honey with diphenhydramine (DPH) on nocturnal pediatric coughs and the sleep quality of children and their parents. This was a clinical trial (registered in IRCT; No...

Extrapyramidal symptoms are an uncommon but well-recognized side effect after the administration of general anesthesia in patients without a significant neurologic history. Several case reports implicate propofol as the likely causative agent producing these symptoms, which include ballismus, dystonia, choreoathetosis, and opisthotonus. Currently, there is no clear consensus on first-line treatment of these symptoms. In each of the published cases, anticholinergic medications and benzodiazepines were central to initial management, although the speed and extent of symptom resolution were variable...
