Diphenhydramine inhibits voltage-gated proton channels (Hv1) and induces acidification in leukemic Jurkat T cells- New insights into the pro-apoptotic effects of antihistaminic drugs.
Authors: Asuaje A, Martín P, Enrique N, Díaz Zegarra LA, Smaldini P, Docena G, Milesi V Abstract An established characteristic of neoplastic cells is their metabolic reprogramming, known as the Warburg effect, with greater reliance on energetically less efficient pathways (such as glycolysis and pentose phosphate shunt) compared with oxidative phosphorylation. This results in an overproduction of acidic species that must be extruded to maintain intracellular homeostasis. We recently described that blocking the proton currents in leukemic cells mediated by Hv1 ion channels triggers a marked intracellul...

Continuous diphenhydramine infusion and imatinib for KIT-D816V-negative mast cell activation syndrome: a case report
ConclusionsContinuous diphenhydramine infusion can provide promising outcomes following the failure of intermittent antihistamine dosing in patients with severe mast cell activation syndrome. Initiating continuous diphenhydramine infusion may be helpful in an intensive care setting when the patient is particularly prone to anaphylaxis and/or the resources needed to manage anaphylaxis are not available outside the intensive care unit. Furthermore, imatinib provides benefits in KIT-D816V-negative mast cell disorders due to other unknown mutations. (Source: Journal of Medical Case Reports)

Acute masseter dystonia in a pediatric patient receiving aripiprazole and methylphenidate following induction of general anesthesia
Summary An 11‐year‐old male receiving aripiprazole, methylphenidate, and clonidine developed acute masseter dystonia inhibiting tracheal intubation after induction of general anesthesia with propofol and rocuronium. Following emergence, he had trismus and jaw discomfort. Psychiatry consultation suspected an acute dystonic reaction, so diphenhydramine was administered intravenously which resolved symptoms. We suspect chronic aripiprazole and methylphenidate usage combined with propofol administration in the short‐term absence of methylphenidate made this patient susceptible to dystonic reactions.

Pharmacologic Treatment of Cannabinoid Hyperemesis Syndrome: A Systematic Review
ConclusionHigh‐quality evidence for pharmacologic treatment of CHS is limited. Benzodiazepines, followed by haloperidol and capsaicin, were most frequently reported as effective for acute treatment, and TCAs for long‐term treatment. As the prevalence of CHS increases, future prospective trials are greatly needed to evaluate and further define optimal pharmacologic treatment of patients with CHS.This article is protected by copyright.

Abstract P3-13-20: Use of a 3-D bioabsorbable tissue marker in 61 patients over two years
Conclusion:The I-SPY 2 adaptive randomization model efficiently evaluates investigational agents in the setting of neoadjuvant BC. The value of I-SPY 2 is that it provides insight as to the regimen's likelihood of success in a phase 3 neoadjuvant study. Although no signature reached the efficacy threshold of 85% likelihood of success in phase 3, we observed the most impact in HR-/HER2- patients, with a 16% improvement in pCR rate. While our data do not support the continued development of Ganetespib alone for neoadjuvant BC, combinations with Ganetespib, which could potentiate its effect, may be worth pursuing in I-SPY 2 o...

Inhibitory effects of antihistamines, diphenhydramine and chlorpheniramine, on proton currents in BV2 microglial cells.
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. Diphenhydramine and chlorpheniramine reduced the proton currents with almost the same potency, yielding IC50 values of 42 and 43μM, respectively. Histamine did not affect proton currents, excluding the involvement of histamine receptors in their action. Neither drug shifted the voltage-dependence of activation or the reversal potential of the proton currents, even though diphenhydramine slowed the activation and deactivation kinetics. The ...

These findings corroborate the profiling of CNS effects to demonstrate pharmacological selectivity, and further support SPV as biomarker for anxiolysis involving GABA‐ergic neurons. The study also supports the use of prolonged mild threat to demonstrate anxi...

Regenerated cellulose capsules for controlled drug delivery: Part IV. In-vitro evaluation of novel self-pore forming regenerated cellulose capsules.
Abstract In the present work, the release mechanisms of active pharmaceutical ingredients (APIs) enclosed in self-pore forming regenerated cellulose (RC) two-piece hard shell capsules are described. The RC capsules were fabricated using a modified dip-coating approach, which yielded an assembled dosage form that was equivalent in size and shape to a conventional gelatin two-piece hard shell capsule. Drug release characteristics from RC capsules were evaluated using potassium chloride, diphenhydramine hydrochloride, tramadol hydrochloride, niacinamide, acetaminophen and ketoprofen as model APIs. The RC capsules act...

A multi-omic approach to elucidate low-dose effects of xenobiotics in zebrafish (Danio rerio) larvae
Publication date: Available online 18 November 2016 Source:Aquatic Toxicology Author(s): Susie S.Y. Huang, Jonathan P. Benskin, Nik Veldhoen, Bharat Chandramouli, Heather Butler, Caren C. Helbing, John R. Cosgrove Regulatory-approved toxicity assays such as the OECD Fish Embryo Toxicity Assay (TG236) allow correlation of chemical exposure to adverse morphological phenotypes. However, these assays are ineffective in assessing sub-lethal (i.e. low-dose) effects, or differentiating between similar phenotypes induced by different chemicals. Inclusion of multi-omic analyses in studies investigating xenobiotic action provides i...
