Effect of the varicella vaccination on the clinical characteristics of herpes zoster cases aged 20 years and under / 中华预防医学杂志

To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q1,Q3)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

Research progress on the incidence and economic burden of herpes zoster disease in immunocompromised population / 中华预防医学杂志

With the increase of age or the impairment of immune function, the specific cellular immune level against varicella zoster virus (VZV) in the body decreases, and the latent VZV in the ganglion can be reactivated to cause herpes zoster (HZ). HZ and its main complication postherpetic neuralgia (PHN) can seriously affect the quality of life of patients. The immunocompromised (IC) population is more prone to HZ than the immunocompetent population due to diseases and therapeutic drugs. This paper reviews the incidence, risk factor and economic burden of HZ in IC population with special health status, to provide ideas for research and adjustment of immunization strategies in the future.

Burden of herpes zoster among Brazilian adults: a hospital-based study / Carga da herpes zoster em adultos brasileiros: um estudo de base hospitalar

OBJECTIVE: To describe the clinical features of herpes zoster in adult patients treated at a large tertiary care hospital in Brazil over a 5-year period. METHODS: The medical records of suspected herpes zoster cases (based on ICD-10 codes) were identified for full review. Convenience sampling was used to select the medical records from a tertiary hospital in São Paulo. We collected data about co-existing medical conditions, medication use, herpes zoster-related clinical features and outcomes, and healthcare resource utilization. RESULTS: A total of 249 individuals whose first episode of herpes zoster occurred between 2010 and 2014 were included. The mean patient age was 55 years (range 18­96), and the majority were women (63.05%) and aged ≥ 50 years (63.86%). Medical comorbidities were reported in 92.77%, including diabetes (19.68%) and HIV infection (7.63%). Current/recent use of immunosuppressive agents was reported in 31.73%. A total of 65.86% of the patients were hospitalized: 102 patients (40.96%) were admitted for herpes zoster management, while 62 (24.90%) were already receiving inpatient care. The mean hospital length of stay was 16.60 days. One-third (34.14%) were managed as outpatients. Postherpetic neuralgia was reported as a complication in 18.07%. CONCLUSIONS: This retrospective descriptive study found a high frequency of herpes zoster episodes in older adults with comorbidities who sought medical care at a tertiary hospital. These results also underscore the importance of understanding the epidemiology of this disease and developing control strategies for these at-risk populations in Brazil.

Tissue-Clearing Technique and Cutaneous Nerve Biopsies: Quantification of the Intraepidermal Nerve-Fiber Density Using Active Clarity Technique-Pressure Related Efficient and Stable Transfer of Macromolecules Into Organs

BACKGROUND AND PURPOSE: Cutaneous nerve biopsies based on two-dimensional analysis have been regarded as a creditable assessment tool for diagnosing peripheral neuropathies. However, advancements in methodological imaging are required for the analysis of intact structures of peripheral nerve fibers. A tissue-clearing and labeling technique facilitates three-dimensional imaging of internal structures in unsectioned, whole biological tissues without excessive time or labor costs. We sought to establish whether a tissue-clearing and labeling technique could be used for the diagnostic evaluation of peripheral neuropathies. METHODS: Five healthy individuals and four patients with small-fiber neuropathy (SFN) and postherpetic neuralgia (PHN) were prospectively enrolled. The conventional methods of indirect immunofluorescence (IF) and bright-field immunohistochemistry (IHC) were adopted in addition to the tissue-clearing and labeling method called active clarity technique-pressure related efficient and stable transfer of macromolecules into organs (ACT-PRESTO) to quantify the intraepidermal nerve-fiber density (IENFD). RESULTS: The mean IENFD values obtained by IF, bright-field IHC, and ACT-PRESTO in the healthy control group were 6.54, 6.44, and 90.19 fibers/mm², respectively; the corresponding values in the patients with SFN were 1.99, 2.32, and 48.12 fibers/mm², respectively, and 3.06, 2.87, and 47.21 fibers/mm², respectively, in the patients with PHN. CONCLUSIONS: This study has shown that a tissue-clearing method provided not only rapid and highly reproducible three-dimensional images of cutaneous nerve fibers but also yielded reliable quantitative IENFD data. Quantification of the IENFD using a tissue-clearing and labeling technique is a promising way to improve conventional cutaneous nerve biopsies.

A clinico-epidemiological multicenter study of herpes zoster in immunocompetent and immunocompromised hospitalized children

PURPOSE: There are limited population-based data regarding herpes zoster in children. Thus we conducted a multi-institutional epidemiological analysis of herpes zoster in children and comparative analysis according to their immune status. MATERIALS AND METHODS: The study included 126 children under the age of 18 years who were hospitalized for herpes zoster at 8 hospitals in South Korea, between July 2009 and June 2015. The subjects were divided into 2 groups according to their immune status, and medical records were reviewed. RESULTS: There were 61 cases (48.4%) in the immunocompetent group and 65 cases (51.6%) in the immunocompromised group. Median age was older in immunocompromised group (11.4 vs. 8.6) (p<0.001). The mean duration of hospitalization was longer in immunocompromised group (11.0 vs. 6.6) (p<0.001). Patients were treated with oral or intravenous antiviral agents. A total of 12 in immunocompetent group were cured only by oral acyclovir. No treatment failure was found in both groups. Six immunocompromised patients had postherpetic neuralgia and 1 case was in immunocompetent group. In immunocompetent children, herpes zoster was likely caused by early varicella infection. There was no increase in progression of severity in both groups due to appropriate treatment. CONCLUSION: Early initiation of therapy is necessary for those in immunocompromised conditions. And inactivated herpes zoster vaccination may be considered in immunocompromised adolescents in the future.

Suspected transcutaneous cerebral spinal fluid leakage without postural headache after implantable intrathecal drug delivery system removal: A case report

A 55-year-old man with an implantable intrathecal drug delivery system (IDDS) implant removal surgery was performed to control a suspected implant infection. Clear discharge from a lumbar wound was detected after IDDS removal, but transcutaneous cerebral spinal fluid (CSF) leakage was not suspected because the patient did not suffer from a postural headache. Finally, a suspected CSF leakage was resolved with a single epidural blood patch.

Facial Herpes Zoster: A 15-year Retrospective Single-Center Study / 대한피부과학회지

BACKGROUND: Many studies about herpes zoster exist in the Korean dermatologic literature. However, few studies have reported about facial herpes zoster and its complications. OBJECTIVE: The purpose of this study was to investigate the epidemiology, clinical features, and complications of facial herpes zoster. METHODS: We analyzed the medical records of 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized patients into 8 groups based on the dermatomal distribution of herpetic lesions. We investigated the correlations between clinical features, prognosis, and complications. RESULTS: We analyzed the medical records of 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized patients into 8 groups based on the dermatomal distribution of herpetic lesions. We investigated the correlations between clinical features, prognosis, and complications. Results: The most common site of involvement of facial herpes zoster was the ophthalmic branch of the trigeminal nerve (59.2%). Herpes zoster involving the ophthalmic and the maxillary branches of the trigeminal nerves showed a significantly higher incidence rate of herpes zoster ophthalmicus than that observed with herpes zoster involving only the ophthalmic branch (odds ratio 7.373). Age and periorbital swelling were significantly correlated with herpes zoster ophthalmicus (p<0.001). Facial palsy was significantly correlated with otalgia and cutaneous ear involvement (p<0.001). Postherpetic neuralgia (PHN) occurred in 41% of patients with facial herpes zoster. Patients who received antiviral treatment within 3 days showed lower rates of PHN (35.8%) than patients who received treatment after 4 days (45.4%) (p=0.002). CONCLUSION: Facial herpes zoster is associated with several neurological complications. Variables including age, periorbital swelling, otalgia, and cutaneous ear involvement are useful predictors of complications and prognosis. Early institution of antiviral treatment and appropriate interdepartmental consultations are required for better treatment outcomes.

The efficacy of selective nerve root block for the long-term outcome of postherpetic neuralgia / 대한통증학회지

BACKGROUND: Several nerve blocks can reduce the incidence of postherpetic neuralgia (PHN) as well as relieve acute zoster-related pain, but the long-term outcome of PHN has not been clearly determined. This study investigated the efficacy of selective nerve root block (SNRB) for herpes zoster (HZ) on the long-term outcome of PHN. METHODS: We prospectively conducted an interview of patients who had undergone an SNRB for HZ from January 2006 to December 2016 to evaluate their long-term PHN status. The relationship between the time from HZ onset to the first SNRB and the long-term outcome of PHN was investigated. RESULTS: The data of 67 patients were collected. The patients were allocated to acute (SNRB ≤ 14 days, n = 16) or subacute (SNRB > 14 days, n = 51) groups. The proportions of cured patients were 62.5% and 25.5% in the acute and subacute groups (P = 0.007), respectively. In logistic regression, an SNRB >14 days was the significant predictor of PHN (adjusted odd ratio, 3.89; 95% confidence interval, 1.02–14.93; P = 0.047). Kaplan–Meier analysis revealed that time from the SNRB to the cure of PHN was significantly shorter in the acute group (2.4 ± 0.7 yr) than in the subacute group (5.0 ± 0.4 yr; P = 0.003). CONCLUSIONS: An early SNRB during the acute stage of HZ (within 14 days) appears to decrease the incidence and shorten the duration of PHN, with a median of 5.0 years of follow-up.

Postherpetic Neuralgia Aggravated by Upper Complete Denture / 이화의대지

Postherpetic neuralgia (PHN) is a chronic and refractory pain disease. It requires longterm treatment and follow-up. Comorbid diseases can change or aggravate the pain condition and responsiveness of patients to PHN treatment. In such cases, the cause of pain should be identified through proper testing, and appropriate treatment should be administered. Herein, we report the case of a 67-year-old man with PHN in the maxillary nerve. As the pain was being controlled with medication and infraorbital nerve block, the patient experienced deterioration of pain caused by a newly worn upper complete denture. The patient's pain was relieved following correction of the upper complete denture.

Measuring herpes zoster disease burden in São Paulo, Brazil: a clinico-epidemiological single-center study

OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital's emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor's office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.

Usefulness of Inflammatory Markers for the Prediction of Postherpetic Neuralgia in Patients with Acute Herpes Zoster

BACKGROUND: Increasing evidence suggests a pivotal role for neuronal inflammation in response to replicating varicella zoster virus in the development of postherpetic neuralgia (PHN). OBJECTIVE: In this study, we investigated the value of serum levels of various inflammatory markers in acute herpes zoster (HZ) as predictors for the development of PHN. METHODS: A total of 116 patients with acute HZ were enrolled in this study. We measured scores on the pain visual analogue scale (VAS) at baseline and at 1, 3, and 6 months after diagnosis of HZ. We defined PHN as pain greater than 1 on the VAS lasting for more than 6 months. Serum samples for laboratory assay, including complete blood count were obtained at the initial visit. Correlations between the levels of each inflammatory marker and the development of PHN were evaluated. RESULTS: Levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), lymphocyte count, and albumin showed significant correlations with development of PHN in univariate analysis. Levels of ESR, CRP, and lymphocyte count also showed significant correlations in multivariate analysis. ESR level showed stronger correlations with development of PHN than levels of CRP and lymphocyte count. CONCLUSION: In this study, we confirmed that elevated ESR was an independent and significant predictor of PHN in patients with acute HZ. To validate these results, further well-designed, randomized clinical trials are needed.

Comprehensive review and update on herpes zoster

Herpes zoster (HZ) is the result of reactivation and multiplication of latent varicella zoster virus that persisted in latent form within the sensory ganglia following an earlier attack of varicella. It occurs most frequently in older adults and immunosuppressed individuals. Classically, the rash presents as painful, erythematous, maculopapular, and vesicular lesions that typically involve single dermatome, and usually do not cross the midline. The diagnosis is mainly made clinically, except in patients with atypical manifestations in which laboratory virologic testing is required. HZ has been associated with several complications, of which postherpetic neuralgia is the most common and debilitating. The treatment of HZ includes the use of antiviral agents, analgesics for control of acute zoster pain, good skin care for healing, and prevention of secondary bacterial infection. Antiviral agents should be started within 72 hours of onset to reduce the severity of the infection, the duration of the eruptive phase, and the intensity of acute pain. The options for treating postherpetic neuralgia include lidocaine patch, high dose capsaicin patch, gabapentin, pregabalin, opioids, and tricyclic antidepressants. A live attenuated zoster vaccine reduces the incidence of by one-half and the incidence of postherpetic neuralgia by two-thirds. We herein review the recent data on the epidemiology, pathophysiology, diagnosis and management of HZ including HZ vaccine.

Use of stellate ganglion block for treatment of recurrent syncope followed by chest pain / 영남의대학술지

Syncope is defined as a transient loss of consciousness and postural tone, characterized by rapid onset, short duration, and spontaneous recovery. Stellate ganglion block (SGB) is a nerve block method that is used for treatment of neuropathic pain in the head, neck and upper extremities, especially trigeminal neuralgia, postherpetic neuralgia and complex regional pain syndrome. SGB can modulate and stabilize the sympathetic nervous system, which prevents it from overexcitation and improves symptoms of syncope. The authors report a patient who was treated for pain and edema of both upper extremities with SGB, then showed improvement in recurrent syncope followed by chest pain and overall quality of life.

Modalities in managing postherpetic neuralgia

Postherpetic neuralgia (PHN) is the most troublesome side effect of Herpes Zoster (HZ), which mainly affects the elderly and immunocompromised populations. Despite the current advancement of treatments, PHN persists in many individuals influencing their daily activities and reducing their quality of life. Anticonvulsants, antidepressants, topical therapies including lidocaine and capsaicin, and opioids, are the most widely used therapies for the treatment of PHN. These medications come with their adverse effects, so they should be used carefully with the elderly or with patients with significant comorbidities. Other measures like botulinum toxin, nerve blocks, spinal cord stimulation, and radiofrequency have also contributed significantly to the management of PHN. However, the efficacy, safety, and tolerability of these invasive methods need to be carefully monitored when administering them. Early diagnosis and early initiation of treatment can reduce the burden associated with PHN. The zoster vaccine has effectively reduced the incidence of HZ and PHN. In this article, we discuss the treatment options available for the management of PHN, mainly focusing on the efficacy and safety of different therapeutic modalities.
