Efficacy and safety of Pien Tze Huang capsules in patients with herpes zoster: A multicenter, randomized, double-blinded, and placebo-controlled trial.

BACKGROUND: Herpes zoster (HZ) is a common medical condition accompanied by several distressing symptoms, including acute pain. Pien Tze Huang (PZH) is a well-known traditional Chinese medicine (TCM) with numerous pharmacological effects, including antiviral properties, neuroprotection, and immunity regulation. PURPOSE: To investigate the efficacy and safety of PZH capsules in patients with HZ. STUDY DESIGN: A multicenter, double-blinded, randomized, and placebo-controlled trial from 8 hospitals in 5 cities of China. METHODS: Eligible participants were randomly assigned to the PZH capsule and placebo group at a 1:1 ratio. Treatment was conducted for 14 days with a window period of no more than 2 days. For the first 7 days, participants received antiviral drugs combined with PZH capsules (0.6 g/time, 3 times a day) or placebos. For the remaining 7 days, they were only treated with PZH capsules (0.6 g/time, 3 times a day) or placebos. RESULTS: We included 222 patients in the full analysis set (FAS), and 187 patients in the per protocol set (PPS). The change of numeric rating scale pain scores from baseline to the seventh day (±1 day) after treatment in the PZH capsule group was statistically superior to the placebo group (FAS: 2.33 vs. 1.71, 97.5%CI: 0.03 ∼ 1.19; PPS: 2.29 vs. 1.51, 97.5%CI: 0.18 ∼ 1.38). In the PPS, there was a significant difference in the time (days) of pain relief between the placebo group and the PZH capsule group (Mean (SD): 5.71 (3.76) vs. 4.69 (3.57), p = 0.046). On the seventh day (±1 day) after treatment, the level of CD8+ cells in the PZH capsule group were higher than those of the placebo group (FAS: Mean (SD): 24.08 (6.81) vs. 21.93 (8.19), p = 0.007; PPS: Mean (SD): 24.26 (6.93) vs. 22.15 (8.51), p = 0.012). The level of cytotoxic lymphocyte cells found similar results on the seventh day (±1 day) (FAS: Mean (SD): 12.17 (4.65) vs. 10.55 (4.15), p = 0.018; PPS: Mean (SD): 12.25 (4.65) vs. 10.11 (3.93), p = 0.002). No serious adverse events were noted and PZH capsules were well tolerated. CONCLUSION: PZH capsules confer therapeutic effects on HZ with the TCM symptom of stagnated heat of liver channel by substantially reducing the pain intensity, shortening the time of pain relief as well as regulating the immune function. On the basis of the efficacy and safety profiles, PZH capsules may be a promising complementary therapy for the treatment of HZ.

Professor FU Wenbin's experience of "acupuncture-moxibustion-consolidation" holistic idea in treatment of laryngeal herpes zoster with vocal cord paralysis. / 符文彬教授整合思维"一针二灸三巩固"模式治疗喉带状疱疹伴声带麻痹的临床经验.

This paper introduces professor FU Wenbin's clinical experience in the treatment of laryngeal herpes zoster with vocal cord paralysis, using the holistic mode of treatment, in which, acupuncture, moxibustion and consolidation regimens are integrated. Regarding the core pathogenesis of the disease, the invaded exogenous toxic heat is transformed into fire that flows to the throat. Soothing liver and releasing heat is the general principle of treatment, guiding the entire process of treatment. For acupuncture regimen, the filiform needling is used and the acupoint prescription is composed of Baihui (GV 20), Yintang (GV 24+), Lianquan (CV 23), the four-gate points (bilateral Hegu [LI 4] and Taichong [LR 3]), the group points for conducting qi back to the primary (Zhongwan [CV 12], Xiawan [CV 10], Qihai [CV 6] and Guanyuan [CV 4]), as well as bilateral Fengchi (GB 20), Wangu (GB 12) and Yifeng (TE 17). Besides, the pricking technique is delivered to the posterior wall of the pharynx for soothing the liver, regulating the spirit, reducing the heat and benefiting the throat. For the moxibustion regimen, moxibustion is applied to Fengchi (GB 20), Feishu (BL 13), the four-flower points (bilateral Geshu [BL 17] and Danshu [BL 19]), Shenshu (BL 23) and Mingmen (GV 4), which nourishes the spleen and stomach and reduces the heat pathogen through the heating action of moxibustion specially. In the stage of consolidation, the bloodletting and cupping technique is used at Xinshu (BL 15), Ganshu (BL 18) and Jianjing (GB 21) to eliminate the liver stagnation and the intradermal needling is delivered to sustain the needling stimulation and consolidate the therapeutic effect.

To analyze the research hotspots, frontiers and trends of fire needle clinical randomized controlled trial (RCT) literature in the past 10 years by using bibliometrics and knowledge mapping methods. Six Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, PubMed and Web of Science ( WOS ) were searched for RCT research literature on fire needle. CiteSpace V6.1.R6 and VOSviewer V1.6.18 software were used to analyze the cooperation network, keyword co-occurrence, keyword clustering, keyword timeline, keyword emergence, etc., and to draw a visual knowledge map. A total of 1 973 Chinese articles and 3 English articles were included. The top three institutions that publish articles were Guangzhou University of CM, Heilongjiang University of CM and Beijing Hospital of TCM Affiliated to Capital Medical University. The fire needle was often combined with acupuncture, cupping and bloodletting therapy in the treatment of acne, vitiligo, lumbar disc herniation, herpes zoster, stroke sequelae, facial paralysis, knee osteoarthritis and so on. The research frontiers included the combined application of fire needle and other therapies, clinical mechanism research and efficacy evaluation index research. In the future, we should expand the dominant diseases, optimize the research design, strengthen the cooperation between the teams, and carry out high-level clinical research.

Crohn's Disease and Herpes Zoster: Being Mindful of Vaccination.

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract. Immunosuppressive therapy is the main treatment modality in Crohn's disease. Herpes zoster (HZ), caused by Varicella-zoster virus, is a relatively common albeit burdensome clinical picture mainly affecting adult population with immunosuppressive status. In this paper, we aimed to report a Crohn's disease patient with HZ to raise awareness on vaccination. There are commercially available vaccines that are shown to be safe and effective against HZ reactivation. Crohn's disease patients should be evaluated and informed about preventive options against HZ to prevent unwanted HZ-related complications.

Effect of high dose vitamin D supplementation on subsequent immune responses to administration of the live herpes zoster vaccine to long-term care residents.

Thirty-three long-term care residents (mean age 76.5 years), who were participating in a study in which they were randomized to receive either oral daily standard dose (400-1000 IU/day) 25-hydroxy vitamin D (vitamin D3) (SD) or high dose (3000-4000 IU/day) (HD) vitamin D3, were vaccinated with the live, attenuated herpes zoster vaccine. Blood was drawn at vaccination and three weeks later to determine varicella-zoster virus (VZV) antibody and T-cell mediated immune responses. ELISA and neutralizing antibodies increased significantly, but to the same extent, in both groups. The antibody avidity significantly increased from pre- to post-vaccination only in the HD group. VZV-CMI, as measured by FLUOROSPOT significantly increased post-vaccination in both groups, but the difference in interferon-γ spot-forming cells (SFC) and interleukin-2 SFC was lower in the HD than SD group. The increase in VZV-CMI correlated inversely with circulating regulatory T cells in the HD group. We conclude that pre-treatment with HD vitamin D3 does not appreciably enhance the antibody response to a live vaccine and that VZV-CMI responses were diminished in HD vitamin D3 recipients.

Augmentation of immune response to vaccinations through osteopathic manipulative treatment: a study of procedure.

CONTEXT: Anecdotal evidence suggested that osteopathic manipulative treatment (OMT) may have imparted survivability to patients in osteopathic hospitals during the 1918 influenza pandemic. In addition, previous OMT research publications throughout the past century have shown evidence of increased lymphatic movement, resulting in improved immunologic function qualitatively and quantitatively. OBJECTIVES: The following is a description of a proposed protocol to evaluate OMT effects on antibody generation in the peripheral circulation in response to a vaccine and its possible use in the augmentation of various vaccines. This protocol will serve as a template for OMT vaccination studies, and by adhering to the gold standard of randomized controlled trials (RCTs), future studies utilizing this outline may contribute to the much-needed advancement of the scientific literature in this field. METHODS: This manuscript intends to describe a protocol that will demonstrate increased antibody titers to a vaccine through OMT utilized in previous historical studies. Confirmation data will follow this manuscript validating the protocol. Study participants will be divided into groups with and without OMT with lymphatic pumps. Each group will receive the corresponding vaccine and have antibody titers measured against the specific vaccine pathogen drawn at determined intervals. RESULTS: These results will be statistically evaluated. Our demonstration of a rational scientific OMT vaccine antibody augmentation will serve as the standard for such investigation that will be reported in the future. These vaccines could include COVID-19 mRNA, influenza, shingles, rabies, and various others. The antibody response to vaccines is the resulting conclusion of its administration. Osteopathic manipulative medicine (OMM) lymphatic pumps have, in the past through anecdotal reports and smaller pilot studies, shown effectiveness on peripheral immune augmentation to vaccines. CONCLUSIONS: This described protocol will be the template for more extensive scientific studies supporting osteopathic medicine's benefit on vaccine response. The initial vaccine studies will include the COVID-19 mRNA, influenza, shingles, and rabies vaccines.

Combination of phototherapy for treatment of labial necrotizing lesion: case report

Lip necrotizing lesions are painful, complex to heal, and negatively impact the patient's orofacial condition. The present study reports a clinical case of a necrotizing lesion on the lower lip in a 38-year-old male patient, previously healthy, five days after receiving the first dose of the SARS-COV-2 vaccine, with an initial diagnosis of labial herpes zoster, with secondary infection and unsatisfactory response to clinical treatment. After debridement of the necrotic tissue, followed by a combination of antimicrobial photodynamic therapy (aPDT), photobiomodulation therapy (PBMT) and hydrofiber dressing with silver, the patient evolved with complete healing of the lip lesion and satisfactory restoration of orofacial functions after 7 days. According to the present case report, this combination of phototherapy modalities suggests to be a promising tool for the treatment of necrotizing labial lesions.

Effectiveness of the live zoster vaccine during the 10 years following vaccination: real world cohort study using electronic health records.

OBJECTIVES: To assess the effectiveness of live zoster vaccine during more than 10 years after vaccination; and to describe methods for ascertaining vaccine effectiveness in the context of waning. DESIGN: Real world cohort study using electronic health records. SETTING: Kaiser Permanente Northern California, an integrated healthcare delivery system in the US, 1 January 2007 to 31 December 2018. POPULATION: More than 1.5 million people aged 50 years and older followed for almost 9.4 million person years. MAIN OUTCOME MEASURE: Vaccine effectiveness in preventing herpes zoster, postherpetic neuralgia, herpes zoster ophthalmicus, and admission to hospital for herpes zoster was assessed. Change in vaccine effectiveness by time since vaccination was examined using Cox regression with a calendar timeline. Time varying indicators were specified for each interval of time since vaccination (30 days to less than one year, one to less than two years, etc) and adjusted for covariates. RESULTS: Of 1 505 647 people, 507 444 (34%) were vaccinated with live zoster vaccine. Among 75 135 incident herpes zoster cases, 4982 (7%) developed postherpetic neuralgia, 4439 (6%) had herpes zoster ophthalmicus, and 556 (0.7%) were admitted to hospital for herpes zoster. For each outcome, vaccine effectiveness was highest in the first year after vaccination and decreased substantially over time. Against herpes zoster, vaccine effectiveness waned from 67% (95% confidence interval 65% to 69%) in the first year to 15% (5% to 24%) after 10 years. Against postherpetic neuralgia, vaccine effectiveness waned from 83% (78% to 87%) to 41% (17% to 59%) after 10 years. Against herpes zoster ophthalmicus, vaccine effectiveness waned from 71% (63% to 76%) to 29% (18% to 39%) during five to less than eight years. Against admission to hospital for herpes zoster, vaccine effectiveness waned from 90% (67% to 97%) to 53% (25% to 70%) during five to less than eight years. Across all follow-up time, overall vaccine effectiveness was 46% (45% to 47%) against herpes zoster, 62% (59% to 65%) against postherpetic neuralgia, 45% (40% to 49%) against herpes zoster ophthalmicus, and 66% (55% to 74%) against admission to hospital for herpes zoster. CONCLUSIONS: Live zoster vaccine was effective initially. Vaccine effectiveness waned substantially yet some protection remained 10 years after vaccination. After 10 years, protection was low against herpes zoster but higher against postherpetic neuralgia. TRIAL REGISTRATION: ClinicalTrials.gov number NCT01600079; EU PAS register number EUPAS17502.

[Clinical efficacy of fire needling combined with cupping therapy on herpes zoster of acute stage and the effect on Th17/Treg cellular immune balance].

OBJECTIVE: To compare the clinical efficacy between the combined therapy of fire needling and cupping, and western medication on herpes zoster of acute stage, as well as the effects on Th17 and Treg cells and inflammatory factors, i.e. IL-10 and IL-17 in the peripheral blood. METHODS: Eighty patients with herpes zoster of acute stage were randomly divided into a combined therapy (fire needling plus cupping) group and a western medication group, 40 cases in each one. In the combined therapy group, the pricking and scattering techniques with fire needle were used at ashi points and Jiaji (EX-B 2) corresponding to the affected spinal segments; afterwards, cupping therapy was delivered. The combined treatment was given once daily. In the western medication group, valaciclovir hydrochloride tablet and vitamin B1 tablet were administered orally. The duration of treatment in each group was 10 days. Before each treatment from day 1 to day 10 and on day 11 , the score of symptoms and physical signs was observed in the two groups separately. Before each treatment from day 1 to day 10 and on day 11, 30, 60, the score of visual analogue scale (VAS) and skin lesion indexes were observed in the two groups. On day 60, the incidence of postherpetic neuralgia was recorded in the two groups. The levels of Th17 and Treg cells, Th17/Treg ratio in the peripheral blood, as well as serum levels of IL-10 and IL-17 were detected before and after treatment in the two groups. The clinical efficacy was compared between the two groups. RESULTS: From day 6 to day 10 during treatment and on day 11, the scores of symptoms and physical signs in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 3, day 6 to day 10 during treatment and day 11, day 30, VAS scores in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 60, the incidence of postherpetic neuralgia in the combined therapy group was lower compared with that in the western medication group (P<0.05). The blister arresting time and scabbing time in the combined therapy group were shorter than those of the western medication group (P<0.05). After treatment, the level of Th17, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 were all lower in comparison with those in the western medication group (P<0.05). The curative and remarkably effective rate was 82.5% (33/40) in the combined therapy group, higher than 62.5% (25/40) in the western medication group (P<0.05). CONCLUSION: The early application of fire needling combined with cupping therapy can effectively treat herpes zoster of acute stage, relieve pain, and reduce the incidence of postherpetic neuralgia, which may be related to reducing the levels of Th17 and Treg cells, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 so that the cellular immune balance is modulated.

Comparison of efficacy of acupuncture-related therapy in the treatment of herpes zoster: A network meta-analysis of randomized controlled trials.

OBJECTIVE: A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted to evaluate the efficacy and safety of acupuncture-related therapy in the treatment of herpes zoster (HZ) and to provide a reference for the clinical treatment of herpes zoster. METHODS: PubMed, Cochrane Library, EMBASE, Web of Science, CNKI, VIP database, Wanfang Database, and SinoMED Chinese and English databases were systematically searched for RCTs on acupuncture-related therapy for HZ until February 2023. Literature screening, data extraction, and risk of bias assessment were performed independently by 2 researchers. R4.2.1 and Stata15.1 software were used for data analysis. RESULTS: A total of 26 RCTs involving 1929 HZ patients were included, and the network meta-analysis results showed that acupotomy appeared to be most effective in terms of improving VAS scores and the time of incrustation; SUCRA cumulative probability ranking showed the best efficacy of bloodletting in improving efficiency and the time of ceasing new blisters, acupuncture in improving the time of decrustation, and moxibustion in reducing the incidence of postherpetic neuralgia (PHN). CONCLUSIONS: Through a comprehensive comparison of 9 different acupuncture therapies, acupotomy was the optimal treatment to improve VAS pain scores and the time of incrustation; bloodletting, acupuncture, fire needle, and moxibustion could be effective intervention measures to improve the time of ceasing new blisters and decrustation and reduce the incidence of PHN; Western medicine was closely related to adverse reactions. The conclusions need to be further verified due to the limitations of the study.

The Homeopathic Approach to the Treatment of Acute Herpes Zoster.

Despite its demonstrated efficacy, the conventional pharmacologic approach to the treatment of Herpes zoster often has shortcomings-delayed treatment response times, limited treatment window to prevent PHN, and outright treatment failures. It is obvious in light of the foregoing evidence that other treatment options merit consideration, complementary and/or alternative medical disciplines among them. Homeopathic medicine, based on extensive clinical experience, coupled with its remarkable safety profile and convenience of administration, is one such discipline.

Clinical efficacy of LED golden light combined with acyclovir in the treatment of herpes zoster: a single-center prospective study.

This study aimed to explore the safety and clinical efficacy of light emitting diode (LED) golden light combined with acyclovir in treating herpes zoster (HZ). According to the random number table, 54 inpatients with HZ were divided into control group, golden-light group, and red-light group, with 18 cases in each group. The control group received acyclovir intravenous drip, while the patients in the red-light group received acyclovir intravenous drip and red-light LED phototherapy, and the golden-light group received acyclovir intravenous drip and golden-light LED phototherapy. Primary assessments included herpes stopping time, incrustation time, decrustation time, pain visual analog scale scores (VAS), and incidence of postherpetic neuralgia (PHN) on the 30th and 90th days. Golden-light group and red-light group showed a shorter herpes stopping time, incrustation time, and decrustation time (P < 0.05) compared to the control group (P < 0.05), while the golden-light group showed a shorter incrustation time and decrustation time than the red light group (all P < 0.05). After treatment VAS scores, the golden-light group showed a significant improvement compared to the control group. The golden-light group showed a better PHN incidence than the control group at 30 days follow-up. Compared with the comprehensive curative effect, the total effective rates of the golden-light group, red-light group, and control group were 88.89%, 77.78%, and 72.22%, respectively, and the efficacy of the golden-light group was better than that of the control group and red-light group. Golden light combined with acyclovir can shorten the course of HZ, relieve pain, and reduce the occurrence of PHN, and the effect is better than that of the red-light group and the control group.

Segmental zoster paresis of the lower extremity: Case report.

Herpes zoster (HZ) is a segmental vesicular eruption, pain, and sensorial symptoms. Segmental motor weakness can rarely be seen as a complication of HZ. Here, we present two cases of motor paresis associated with HZ, case 1 was L2 and L3 segmental motor paresis with femoral neuropathy and case 2 was L5 and S1 segmental motor paresis with sensorial ganglion involvement. In both cases after electrotherapy, exercise program, and medication for pain, there were no motor weakness and pain. Zoster motor paresis is a rare complication that responds to treatment and physicians should be careful about its presence in clinical follow-up.

Effect of Herpes Zoster Treatment and Sudden Sensorineural Hearing Loss Using National Health Insurance Claims Data of South Korea.

Background and objectives: Herpes zoster (HZ) is caused by the reactivation of a pre-existing latent varicella zoster virus, which is one of the viruses that causes hearing loss, and hearing loss may occur due to a systemic immune response even if it does not invade the auditory nerve. This study aimed to determine the correlation between sudden sensorineural hearing loss (SSNHL) in older adult patients who received HZ treatment. Materials and Methods: We used the cohort data of patients aged 60 years and above (n = 624,646) between 2002 and 2015 provided by the National Health Insurance Service. The patients were divided into two groups: those who were diagnosed with HZ between 2003 and 2008 (group H, n = 36,121) and those who had not been diagnosed with HZ between 2002 and 2015 (group C, n = 584,329). Results: In the main model (adjusted HR = 0.890, 95% CI = 0.839-0.944, p < 0.001) adjusted for sex, age, and income, and the full model (adjusted HR = 0.894, 95% CI = 0.843-0.949, p < 0.001) adjusted for all comorbidities, group H had a lower risk of SSNHL than group C. Conclusions: This study showed that patients who received HZ treatment had a lower incidence of SSNHL within five years after diagnosis.

Comparison of human monkeypox, chickenpox and smallpox: a comprehensive review of pathology and dermatological manifestations.

Variola virus, the causing agent of smallpox, was eradicated in 1980s and today no new cases are reported. The first human infectious illness to be eliminated globally is variola. On the contrary to Variola, monkeypox, which is a zoonotic and variola-like disease, has nowadays turned to be a major health problem worldwide. VZV is a neurotropic virus and the cause of varicella (chickenpox) and herpes zoster (shingles), which is also a highly infectious disease, especially prevalent in children. These three skin diseases-monkeypox, smallpox, and chickenpox-are frequently mistaken with one another due to similar manifestations including fever, rash, myalgia, chills and headache, but they can all be distinguished by their distinctive symptoms. Although these rash-causing disorders might present different skin lesions; diagnostic tests can be extremely useful in their differentiation. We searched for these concepts on a search engine like Google Scholar, scanning the results for alternative words and phrases, and examined relevant abstracts or articles for alternative words. The clinical diagnosis of monkeypox infection is commonly made based on the occurrence pattern of its skin rash. It is possible in varicella to concurrently identify lesions in their various stages including macular, papular, vesicular, pustular, and crusts; however, monkeypox lesions are all in the same stage and evolve with the same rate. In this review, we have tried to provide a holistic and comprehensive comparison between these three skin infections with a focus on the newly epidemic monkeypox, bringing about the most recent knowledge about its features and its diagnosis.

Severe Herpes Zoster Secondary to Systemic Lupus Erythematosus Successfully Treated with Ultraviolet A1 Phototherapy: A Case Report.

Background: The incidence of herpes zoster (HZ) in systemic lupus erythematosus (SLE) patients is high, and the symptoms are usually severe and resistant to treatment, and the prognosis is poor. Ultraviolet (UV) A1 is a band of UV light, and UVA1 phototherapy has been widely used to treat various inflammatory skin diseases. Objective: At present, UVA1 has been considered as a potential adjuvant therapy for HZ in SLE patients. To the best of our knowledge, this is the first case report concerning the successful application of UVA1 in the treatment of HZ secondary to SLE. Methods: In this article, a clinical case report is presented, wherein the patient did not respond to conventional treatment, but was markedly responsive to the treatment of UVA1 phototherapy, and well tolerated. Results: A 29-year-old woman with severe HZ secondary to SLE was successfully treated with UVA1 phototherapy. Conclusions: UVA1 phototherapy can be used as an effective adjuvant treatment for HZ secondary to SLE.

Systematic review with network meta-analysis: Risk of Herpes zoster with biological therapies and small molecules in inflammatory bowel disease.

BACKGROUND: Biologics and small molecules for inflammatory bowel disease (IBD) may increase infection risk. Herpes zoster causes acute and long-term symptoms, but vaccination is not recommended in patients with IBD, unless >50 years of age. AIMS: To examine risk of Herpes zoster infection with all licensed biologics and small molecules for IBD using network meta-analysis. METHODS: We searched the literature to 4th October 2022, for randomised controlled trials of these drugs in luminal Crohn's disease or ulcerative colitis reporting data on occurrence of Herpes zoster infection during follow-up. We used a frequentist approach and a random effects model, pooling data as relative risks (RRs) with 95% confidence intervals (CIs). RESULTS: We identified 25 trials (9935 patients). Only tofacitinib 10 mg b.d. (RR = 6.90; 95% CI 1.56-30.63, number needed to harm (NNH) = 97; 95% CI 19-1022) and upadacitinib 45 mg o.d. (RR = 7.89; 95% CI 1.04-59.59, NNH = 83; 95% CI 10-14,305) were significantly more likely to increase risk of Herpes zoster infection. Janus kinase inhibitors were the most likely drug class to increase risk of infection, and risk increased with higher doses (RR with lowest dose = 3.16; 95% CI 1.02-9.84, NNH = 265; 95% CI 65-28,610, RR with higher dose = 5.91; 95% CI 2.21-15.82, NNH = 117; 95% CI 39-473). CONCLUSIONS: In a network meta-analysis, the janus kinase inhibitor tofacitinib, and all janus kinase inhibitors considered as a class, were most likely to increase risk of Herpes zoster infection. Risk increased with higher doses.
