The comparative efficacy and safety of herpes zoster vaccines: A network meta-analysis.

Vaccine 2019 Apr 11. Epub 2019 Apr 11.

ICON plc, De Molen 84, Houten 3995 AX, the Netherlands.

Background: We estimated the relative efficacy and safety of vaccines for prevention of herpes zoster (HZ) using network meta-analysis (NMA) based on evidence from randomized controlled trials.

Methods: A systematic literature review evaluated two different HZ vaccines: adjuvanted recombinant zoster vaccine (RZV) and zoster vaccine live (ZVL), with different formulations assessed. Detailed feasibility assessment indicated that a NMA was feasible for efficacy (incidence of HZ and postherpetic neuralgia [PHN]) and safety (serious adverse events [SAE] and reactogenicity [injection-site reactions, systemic reaction]) outcomes.

The efficacy of pregabalin for the treatment of neuropathic pain in Japanese subjects with moderate or severe baseline pain.

J Pain Res 2019 22;12:1061-1068. Epub 2019 Mar 22.

Global Statistics, Pfizer Inc, New York, NY, USA.

Purpose: Although analyses of pooled clinical trial data have reported how international populations respond to pregabalin by baseline neuropathic pain (NeP) severity, no studies have evaluated this specifically in patients from Japan. Thus, this post hoc pooled analysis evaluated the efficacy of pregabalin in Japanese subjects for treating moderate or severe baseline NeP.

Patients And Methods: Data were pooled from three placebo-controlled trials enrolling Japanese subjects with postherpetic neuralgia (PHN), diabetic peripheral neuropathy (DPN), and spinal cord injury (SCI). Read More

Effects of mirogabalin, a novel ligand for the α₂δ subunit of voltage-gated calcium channels, on N-type calcium channel currents of rat dorsal root ganglion culture neurons.

Pharmazie 2019 Mar;74(3):147-149

Mirogabalin, which is a novel ligand for the α₂δ subunit of voltage-gated calcium channels, is being developed for treating neuropathic pain including diabetic peripheral neuropathy and postherpetic neuralgia. Mirogabalin possesses unique α₂δ subunit binding characteristics and has potent and long-lasting analgesic effects in neuropathic pain models. In the present study, we investigated the effects of mirogabalin on N-type calcium channel currents of the rat dorsal root ganglion (DRG) culture neurons using the whole-cell patch clamp technique.

Herbal medicinal products or preparations for neuropathic pain.

Cochrane Database Syst Rev 2019 Apr 2;4:CD010528. Epub 2019 Apr 2.

School of Health Sciences, Ulster University, Jordanstown campus, Shore Road, Newtownabbey, County Antrim, UK, BT37 0QB.

Background: Neuropathic pain is a consequence of damage to the central nervous system (CNS), for example, cerebrovascular accident, multiple sclerosis or spinal cord injury, or peripheral nervous system (PNS), for example, painful diabetic neuropathy (PDN), postherpetic neuralgia (PHN), or surgery. Evidence suggests that people suffering from neuropathic pain are likely to seek alternative modes of pain relief such as herbal medicinal products due to adverse events brought about by current pharmacological agents used to treat neuropathic pain. This review includes studies in which participants were treated with herbal medicinal products (topically or ingested) who had experienced neuropathic pain for at least three months. Read More

Rethinking the causes of pain in herpes zoster and postherpetic neuralgia: the ectopic pacemaker hypothesis.

Authors:
Marshall Devor

Pain Rep 2018 Nov 7;3(6):e702. Epub 2018 Nov 7.

Department of Cell and Developmental Biology, Institute of Life Sciences, and Center for Research on Pain, The Hebrew University of Jerusalem, Jerusalem, Israel.

Introduction: Pain in herpes zoster (HZ) and postherpetic neuralgia (PHN) is traditionally explained in terms of 2 processes: irritable nociceptors in the rash-inflamed skin and, later, deafferentation due to destruction of sensory neurons in one virally infected dorsal root ganglion.

Objectives And Methods: Consideration of the evidence supporting this explanation in light of contemporary understanding of the pain system finds it wanting. An alternative hypothesis is proposed as a replacement. Read More

Genital Herpes Zoster as Possible Indicator of HIV Infection.

Acta Dermatovenerol Croat 2018 Dec;26(4):337-338

Associate Professor Suzana Ljubojević Hadžavdić, MD, PhD, Department of Dermatology and Venereology, University Hospital Center Zagreb, University of Zagreb School of Medicine, Šalata 4, 10000 Zagreb, Croatia;

Herpes zoster (HZ) is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus (VZV) (1). It is a frequent medical condition with an incidence rate of 2-3 cases per 1000 person/years in the general population and 7-10 cases per 1000 person/years after the age of 50 (1,2). Risk factors and triggers for reactivation of HZV have not yet been determined precisely, but are likely to include malignancies, immune deficiencies, solid organ and bone marrow transplant recipients, autoimmune diseases, psychological conditions, emotional stress, human immunodeficiency virus (HIV) infection, and other patients receiving immunosuppressive therapies (1,3).

Severe Herpes Zoster Following Varicella Vaccination in Immunocompetent Young Children.

J Child Neurol 2019 Jan 10:883073818821498. Epub 2019 Jan 10.

4 Division of Child Neurology, Children's Hospital, University of Iowa, Iowa City, IA, USA.

Varicella vaccination is now virtually universal in North America, as well as in some European and Asian countries. Since varicella vaccine is a live attenuated virus, the virus replicates in the skin after administration and can travel via sensory nerves or viremia to become latent in the dorsal root ganglia. In some immunized children, virus reactivates within a few months to a few years to cause the dermatomal exanthem known as herpes zoster (shingles). Read More

Cervical and High-Thoracic Dorsal Root Ganglion Stimulation in Chronic Neuropathic Pain.

Neuromodulation 2019 Jan 8. Epub 2019 Jan 8.

Department of Functional Neurosurgery and Stereotaxy, Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Germany.

Introduction: Dorsal root ganglion stimulation is a meanwhile established but rather new technique of neuromodulation to treat chronic pain states of different origin. While being primarily used in the lumbar region, dorsal root ganglion (DRG) stimulation also can be used in the upper thoracic and cervical region with slight alterations of the surgical approach. This offers new therapeutic options especially in the treatment of neuropathic pain states of the upper extremities. Read More

Bidirectional alterations in ALFF across slow-5 and slow-4 frequencies in the brains of postherpetic neuralgia patients.

J Pain Res 2019 18;12:39-47. Epub 2018 Dec 18.

Department of Pain, The First Affiliated Hospital, Nanchang University, Nanchang, Jiangxi, People's Republic of China,

Purpose: Postherpetic neuralgia (PHN) detrimentally affects brain function. Recent studies have suggested that frequency-dependent changes in electroencephalography in chronic pain patients and blood oxygenation level dependent (BOLD) fluctuations can reflect neuronal activity in different frequencies. The current study aimed to investigate PHN-related brain oscillatory activity in a specific frequency band by using the amplitude of low-frequency fluctuation (ALFF) method. Read More

J Pain 2019 Apr 5;20(4):369-393. Epub 2018 Dec 5.

Department of Anesthesiology and Washington University Pain Center, Washington University School of Medicine, St Louis, MO.

Peripheral neuropathic pain is among the most prevalent types of neuropathic pain. No comprehensive peripheral neuropathic pain classification system that incorporates contemporary clinical, diagnostic, biological, and psychological information exists. To address this need, this article covers the taxonomy for 4 focal or segmental peripheral neuropathic pain disorders, as part of the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership and the American Pain Society (APS) collaborative to develop a standardized, evidence-based taxonomy initiative: the ACTTION-APS Pain Taxonomy (AAPT).

Department of Pediatrics, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA.

Varicella-zoster virus (VZV) is a pathogenic human herpes virus that causes varicella (chickenpox) as a primary infection, following which it becomes latent in peripheral ganglia. Decades later, the virus may reactivate either spontaneously or after a number of triggering factors to cause herpes zoster (shingles). Varicella and its complications are more severe in the immunosuppressed. Read More
