Genetic insights into the gut microbiota, herpes zoster, and postherpetic neuralgia: a bidirectional two-sample Mendelian randomization study

BackgroundAn increasing amount of evidence suggests that gastrointestinal diseases are risk factors for herpes zoster (HZ) and postherpetic neuralgia (PHN). Among them, the gut microbiota may play a crucial role in this process. Therefore, this study aims to explore the potential causal association between the gut microbiota and HZ and PHN.MethodsBidirectional two-sample Mendelian randomization (MR) analysis was used to detect the causal effect between HZ and PHN and the gut microbiota. Gut microbiota data were derived from the MiBioGen consortium, while HZ and PHN data were obtained from the FinnGen database. We selected single-nucleotide polymorphisms (SNPs) as instrumental variables with a threshold of p < 1 × 10⁻⁵ for the association with the gut microbiota in forward MR analysis and p < 5 × 10⁻8 for the association with HZ or PHN in reverse MR analysis and then removed SNPs in linkage disequilibrium (r2 < 0.001) within a distance of 10,000 kb for both the gut microbiota and HZ and PHN. These SNPs were utilized to assess the causal effect between exposures and outcomes using inverse-variance weighting (IVW), MR–Egger, weighted mean, and weighted median tests.ResultsThe class Deltaproteobacteria, order Desulfovibrionales, family Desulfovibrionaceae, and genus Coprococcus 2 were found to reduce the risk of HZ, while the phylum Cyanobacteria, genus Eubacterium rectale group appeared to increase it. The class Coriobacteriia, order Coriobacteriales, family Coriobacteriaceae, genus Lachnospiraceae NK4A136 and genus Ruminococcaceae UCG011 were found to reduce the risk of PHN, while the genus Candidatus Soleaferrea, genus Eubacterium rectale group, and genus Methanobrevibacter appeared to increase it. Moreover, the onset of HZ was found to increase the level of the genus Eubacterium rectale group. These findings remained robust and unaffected by heterogeneity or horizontal pleiotropy among SNPs in both forward and reverse MR analysis.ConclusionThis MR study provided evidence supporting a potential causal relationship between the gut microbiota and HZ and PHN. Moreover, we found that the causal effect between the gut microbiota and HZ is bidirectional. Further studies are required to clarify the biological mechanisms linking the gut microbiota and these conditions.

Risk Factors and the Effect of Antiviral Prophylaxis for Herpes Zoster in Multiple Myeloma Patients

To study the incidence and risk factors of herpes zoster in patients with multiple myeloma and to evaluate the preventive effect of antiviral therapy. The clinical features of multiple myeloma patients with herpes zoster were retrospectively analyzed, the risk factors of herpes zoster and the effect of antiviral prophylaxis were analyzed. Among 180 patients with multiple myeloma, 23 cases developed herpes zoster (12.8%). The incidence of herpes zoster was 19.1% in patients with renal dysfunction and 23.5% after autologous hematopoietic stem cell transplantation (ASCT). The incidence of herpes zoster was higher in patients receiving bortezomib-containing regimens (21/137, 15.3%) than that in those without bortezomib (2/43, 4.7%), but there was no statistical difference (P =0.067). Antiviral prophylaxis was associated with fewer zoster infections, 8/111(7.2%) developed herpes zoster in patients who received antiviral prophylaxis, and 15/69 (21.7%) in those receiving no prophylaxis(P =0.005). 65.2% of patients with herpes zoster did not receive antiviral prophylaxis. Multivariate analysis showed that bortezomib treatment, AHSCT and renal dysfunction were independent risk factors for multiple myeloma with herpes zoster, while antiviral prophylaxis was independently associated with reducing the risk of herpes zoster. Herpes zoster had no effect on OS in patients with multiple myeloma. The risk of herpes zoster in multiple myeloma patients was increased. Antiviral prophylaxis can reduce the risk of herpes zoster in patients on bortezomib-based therapy.

441. Prior SARS-CoV-2 Diagnosis is a Risk Factor for Herpes Zoster in Younger Adults: A Nested Case-control Study in the EPICC Cohort

Abstract Background Prior studies suggest SARS-CoV-2 (SC2) infection and vaccination are risk factors for the development of Herpes Zoster (HZ). We performed a nested case-control study using data from the Epidemiology, Immunology and Clinical Characteristics of Emerging Infectious Diseases of Pandemic Potential (EPICC) cohort to evaluate the impact of SC2 exposure (positive SC2 test or COVID-19 vaccination) on the odds of HZ diagnosis. Methods The EPICC cohort is comprised primarily of younger (median age 34.6 years) Military Health System (MHS) beneficiaries who were either tested for SC2 and/or received COVID-19 vaccination. MHS Data Repository (MDR) records were evaluated for HZ diagnosis. Information about SC2 diagnosis and COVID-19 vaccination was aggregated from participant survey data and MDR records. Cases were defined as adult participants with an HZ ICD-10 code after 3/1/2020. Controls were selected randomly and matched individually to cases on age, race, sex, and time period. We defined exposure as ≥ 1 SC2 positive test or COVID-19 vaccination 0-365 days before HZ diagnosis. We used conditional logistic regression to explore the association between SC2 diagnosis, or COVID-19 vaccination, and HZ diagnosis, adjusting for comorbidities and HZ vaccination. Results Between 3/2020 and 12/2022, 7,394 were enrolled in the EPICC study, and a total of 94 HZ cases were identified. The median age at HZ diagnosis was 39 years (IQR: 33, 48). There was no difference between the median age of HZ cases with and without SC2 diagnosis (38.5 and 39.4 years respectively, p=0.96). Among HZ cases, 28 (30%) had ≥ 1 SC2 diagnosis in the year prior, compared to 12 controls (13%) (Table 1). Participants with a known history of SC2 diagnosis were more likely to be HZ cases (OR 2.7; 95% CI: 1.3, 5.8), adjusting for HZ vaccination and Charlson Comorbidity Index (Table 2). No significant association was found between COVID-19 vaccination and HZ (OR: 1.0; 95% CI: 0.4, 2.5). Sensitivity analyses (exposure 1-90 days prior to HZ diagnosis) found similar results (Table 2). Conclusion In a cohort primarily comprised of younger individuals, SC2 diagnosis, but not COVID-19 vaccination, was associated with increased risk for HZ diagnosis. Disclosures Mark P.

The value of herpes zoster prevention in people aging with HIV: A narrative review.

Review the evidence on the incidence and impact of herpes zoster among people living with HIV and the potential impact of recombinant zoster vaccine for people aging with HIV. Narrative review. Although antiretroviral therapy has substantially reduced the risk of herpes zoster among people living with HIV, they remain at an increased risk compared with the general population. Among people aging with HIV, aging per se is now the main risk factor for herpes zoster. Beyond pain, herpes zoster is also associated with a risk of sight-threatening complications in case of trigeminal involvement, disseminated diseases and stroke. Post-herpetic neuralgia is also a potential threat to the quality of life of people aging with HIV. The recombinant zoster vaccine has demonstrated high and sustained efficacy in the prevention of herpes zoster, post-herpetic neuralgia, and other herpes zoster complications in the general population. Immunogenicity data among people living with HIV with high CD4+ T-cell count and controlled viral load are comparable to those among the general population. Real-life effectiveness data indicate high vaccine efficacy among immunocompromised patients other than people living with HIV. High vaccine price, vaccine hesitancy, and limited disease and vaccine awareness represent potential hurdles for high vaccine uptake among people aging with HIV in Europe. Herpes zoster, and its complications, is a vaccine-preventable disease of aging people. Given its impact on quality of life, herpes zoster prevention using recombinant zoster vaccine is a safe strategy to be considered in every person aging with HIV.

Prevalence and risk factors of herpes zoster infection in patients with rheumatic diseases not receiving biologic or targeted therapies.

The objective was to study the prevalence and risk factors of herpes zoster (HZ) infection in patients with rheumatic diseases. Consecutive patients with rheumatic diseases not receiving biologic/targeted DMARDs who attended our rheumatology clinics between March and August 2019 were retrospectively reviewed. Episodes of HZ infection since their first clinic attendance were identified. Laboratory results (total white cell count, neutrophil-to-lymphocyte ratio (NLR), serum albumin, globulin, and creatinine) and use of immunosuppressive medications were compared between those with (preceding infection) and without (preceding last visit) HZ infection. Cox regression analysis was performed to identify factors associated with the first HZ infection in all patients. 1,479 patients were studied (88.3% women, age 45.0 ± 15.8years). Systemic lupus erythematosus (SLE) (38.7%) and rheumatoid arthritis (28.3%) were the commonest rheumatic diseases. After a follow-up of 14,715 patient-years (9.9 ± 7.0years), 219 (14.8%) patients developed 258 episodes of HZ infection, giving an overall prevalence of 1.75/100-patient years. The prevalence rates of HZ were highest in SLE and inflammatory myopathies (2.54 and 2.58 per 100 patient-years, respectively). Patients who experienced HZ reactivation were younger, more likely to have SLE, and had significantly lower serum albumin/globulin levels but higher NLR. Significantly more patients with HZ reactivation were using prednisolone and other immunosuppressive drugs in the visits preceding HZ infection. The cumulative risk of having HZ reactivation at 24 and 48months was 4.9% and 7.6%, respectively. Cox regression analysis revealed that a diagnosis of SLE, increasing age, higher NLR, use of cyclophosphamide, and increasing doses of prednisolone, azathioprine, hydroxychloroquine and leflunomide were independently associated with HZ infection. Reactivation of HZ is fairly common in patients with rheumatic diseases. Underlying SLE, age, neutrophil/lymphocyte ratio, and immunosuppressive therapies are independent risk factors. Key Points • Herpes zoster (HZ) infection is fairly common in patients with rheumatic diseases undergoing conventional DMARD or immunosuppressive therapies. • Underlying SLE, increasing age, higher neutrophil/lymphocyte ratio and increasing dosages of immunosuppressive drugs are independent risk factors. • Patients with rheumatic diseases, particularly SLE, should be encouraged to receive HZ vaccination.

Study of risk factors of postherpetic neuralgia

Objective: To analyze the clinical features and risk factors of herpes zoster and the risk factors of postherpetic neuralgia (PHN). Methods: A total of 2 840 patients diagnosed with herpes zoster in Peking University People's Hospital from January 2021 to April 2022 were included. The patients with herpes zoster were aged (59±16), and of which 1 314 (46.3%) patients were male. The patients were divided into PHN group and non-PHN group according to whether the patients with herpes zoster developed PHN. And there were 442 (15.6%) patients developed PHN aged (68±12), and of which 189 (42.8%) were male. The information and medical history of PHN group and non-PHN group were collected. The information of the use of glucocorticoids, immunosuppressive agents, biological agents and targeted medicine within 2 months before herpes zoster occurred, history of surgery within 6 months before herpes zoster occurred, and the duration of PHN were collected. Logistic regression analysis was used to analyze the risk factors of PHN. Results: Out of 2 840 patients, 2 056 (72.4%) with herpes zoster aged 50 years and above. Intercostal nerves was mostly involved in patients with herpes zoster, with a total of 1 532(53.9%). Hypertension (465 cases, 16.4%) accounted for the highest number of patients with chronic diseases, followed by diabetes (337 cases, 11.9%) and coronary heart disease (283 cases, 10.0%). Rheumatoid arthritis (41 cases, 1.4%) accounted for the highest number of patients with connective tissue diseases, followed by Sjogren's syndrome (31 cases, 1.1%), systemic lupus erythematosus (28 cases, 1.0%). Logistic regression analysis showed that age≥50 years old (OR: 4.581; 95%CI: 3.131-6.705),lesion on the upper limb and shoulder (OR: 1.858; 95%CI: 1.129-3.059), hypertension (OR: 1.963; 95%CI: 1.513-2.546) and immunosuppressive treatments (OR: 2.170; 95%CI: 1.254-3.753) were independent risk factors for PHN (all P<0.05). Conclusions: Herpes zoster mostly occurs in people aged 50 and above, and mainly affected intercostal nerves. The most common complications are hypertension and rheumatoid arthritis. Age≥50, lesion on upper limbs and shoulders, hypertension, and immunosuppressive treatments may be independent risk factors of PHN.

Prevalence of and factors associated with herpes zoster in England: a cross-sectional analysis of the Health Survey for England

BackgroundHerpes zoster (commonly called shingles) is caused by the reactivation of varicella zoster virus, and results in substantial morbidity. While the risk of zoster increases significantly with age and immunosuppression, relatively little is known about other risk factors for zoster. Moreover, much evidence to date stems from electronic healthcare or administrative data. Hence, the aim of this study was to explore potential risk factors for herpes zoster using survey data from a nationally-representative sample of the general community-dwelling population in England.MethodsData were extracted from the 2015 Health Survey for England, an annual cross-sectional representative survey of households in England. The lifetime prevalence of self-reported herpes zoster was described by age, gender and other socio-demographic factors, health behaviours (physical activity levels, body mass index, smoking status and alcohol consumption) and clinical conditions, including; diabetes, respiratory, digestive and genito-urinary system and mental health disorders. Logistic regression models were then used to identify possible factors associated with shingles, and results were presented as odds ratios with 95% confidence intervals.ResultsThe lifetime prevalence of shingles among the sample was 11.5% (12.6% among women, 10.3% among men), which increased with age. After adjusting for a range of covariates, increased age, female gender (odds ratio: 1.21; 95%CI: 1.03, 1.43), White ethnic backgrounds (odds ratio: 2.00; 95%CI: 1.40, 2.88), moderate physical activity 7 days per week (odds ratio: 1.29; 95%CI: 1.01, 1.66) and digestive disorders (odds ratio: 1.51; 95%CI: 1.13, 1.51) were each associated with increased odds of having had herpes zoster.ConclusionsAge, gender, ethnicity and digestive disorders may be risk factors for herpes zoster among a nationally representative sample of adults in England. These potential risk factors and possible mechanisms should be further explored using longitudinal studies.

Cumulative incidence of and risk factors for herpes zoster among patients with diabetes mellitus: Results from a 10-year nested case-control study

BackgroundDiabetes mellitus (DM) is a well-known risk factor for herpes zoster (HZ). Data specific to the incidence of and risk factors for HZ among Thai DM patients are scarce. MethodsThis nested case-control study evaluated a 10-year cohort of DM patients (N = 1428) treated at Siriraj Hospital (Bangkok, Thailand). We included 40 cases with ≥1 episode of HZ, and we randomly sampled 175 non-HZ controls. Data were obtained from chart review and the ICD-10 diagnosis code, pharmacy database, and laboratory database. ResultsDuring 2005–2014, the cumulative incidence and incidence rate of HZ among all study patients was 2.80% [95%CI: 2.00–3.79%] and 3.96 [95%CI: 2.90–5.28] per 1000 person-years, respectively. The most common site was trunk (27.5%) followed by zoster ophthalmic (22.5%). Only 1 case required hospitalization. Independent risk factors for HZ included underlying hypertension [aOR: 3.48, 95%CI: 1.28–9.43; p = 0.01], number of hypoglycemic drugs used [aOR: 1.46, 95%CI: 1.03–2.08; p = 0.04], and previous herbal remedy use [aOR: 3.83, 95%CI: 1.06–13.84; p = 0.04]. Higher body mass index was a protective factor against HZ [aOR: 0.89, 95%CI: 0.81–0.98; p = 0.02]. ConclusionThe incidence of HZ among DM patients at our center is comparable to other Asian countries. The identified independent risk factors can be used to discern patients who would benefit most from preventive interventions.

Diabetes and Herpes Zoster Association: A systematic Review and Meta-analysis

Background: Diabetes mellitus is known to be a potential risk factor for herpes zoster (HZ). The aim of the present study was to investigate the relationship between diabetes and HZ statistically. What is the status of diabetes in people with HZ, and are diabetes and HZ associations statistically significant? Answering these questions is the main purpose of this study. Methods: Systematic search was carried out in four major international databases, including PubMed, Scopus, Web of Science, and Google scholar for eligible records between January 2000 and December 2020. The overall prevalence of diabetes in HZ people, studies heterogeneity, as well as geographical distribution were estimated by a random-effect model applied in comprehensive meta-analysis (V2, BioStat) software. Results: Ultimately, 28 studies (29 datasets) were included in the present meta-analysis. The overall prevalence of diabetes in HZ people was estimated to be 12.7% (95% CI: 11.5%- 14%), the highest and lowest prevalence rates were 17.4% and 4% in Southeast Asian and American regions, respectively. Additionally, the odds ratio (OR) results suggested a significant association between HZ and diabetes (OR: 1.28, 95% CI: 1.18-1.38). Conclusion: The results indicate a significant association between HZ and diabetes, and this association should not be neglected. Future studies may reflect the effect of vaccination more seriously by considering this association.

Complications and cost estimations in herpes zoster - a retrospective analysis at a Swiss tertiary dermatology clinic.

Herpes zoster is the common reactivation of latent varicella zoster virus infection and is associated with substantial morbidity and costs. Age, immunosuppression, diabetes and active cancer are important risk factors for developing herpes zoster. The recombinant herpes zoster vaccine is highly effective in preventing this infection. To inform cost-effectiveness analyses of vaccination in risk groups, it is important to define the rates of complications, mortality, and hospitalisation and its costs. In this single-centre, investigator-initiated, retrospective study we analysed herpes zoster patients treated in our tertiary dermatology referral centre between 2005 and 2019. Case costs were calculated using health insurance invoices and by estimating the drug-related costs. The associations between patients' characteristics and complications were assessed using logistic regression models. A total of 355 herpes zoster patients were analysed (mean age 61.5 ± 18.8 years; 56.6% women). The complication rate was 30.1% (n = 107) with post-herpetic neuralgia being the most frequent (37/355, 10.4%). The herpes zoster-related hospitalisation rate was 19.2% (n = 68), the herpes zoster-related mortality rate 0.85% (n = 3). Of all patients, 22.8% (n = 81) had herpes zoster risk factors. The odds ratio for complications (multivariate analysis) was 2.5 (95% confidence interval [CI] 1.12-5.72) in cancer patients and 1.04 (1.02-1.05) for each additional year of age (1.41 for 10 years). The cost ratio (median) of in- vs outpatient treatment was 26.9 (CHF/case 9029 vs 335), of all complicated vs non-complicated herpes zoster patients 6.6 (CHF/case 2203 vs 332) and of complicated vs non-complicated herpes zoster outpatients 4.3 (CHF/case 1331 vs 306). In this herpes zoster population at a university hospital, one in three patients was affected by herpes zoster-related complications. Age and cancer were independently associated with a high complication rate, suggesting a need to vaccinate cancer patients. Herpes zoster-related complications and the need for inpatient treatment escalated the costs per case.

Plantar fascial fibromatosis and herpes zoster.

PurposeInfection, chronic pain and depression are considered risk factors for herpes zoster (HZ). However, the correlation between plantar fascial fibromatosis (PFF) and HZ remains unknown. This study investigated HZ risk in patients with PFF.MethodsData was extracted from the Longitudinal Health Insurance Database 2000, which is a subsample of the Taiwan National Health Insurance (NHI) Research Database and contains 1 million NHI beneficiaries. Between 2000 and 2012, patients diagnosed as having PFF were included in the case cohort. Every case was age and sex-matched with individuals without PFF through 1:4 frequency matching (control cohort). The end of the follow-up was defined as December 31, 2013, the date of HZ diagnosis, death, emigration, or withdrawal from the NHI program.ResultsIn total, 4,729 patients were diagnosed as having PFF and were matched with 18,916 individuals without PFF. Patients with PFF were 1.23 times more likely to develop HZ than were those without PFF. Among those aged ≥65 years, patients with PFF had a higher HZ risk than did those without PFF (adjusted hazard ratio [aHR] = 1.48). Men with PFF had a significantly higher risk of HZ than did men without PFF (aHR = 1.44).ConclusionPatients with PFF, particularly older and male patients, having a high HZ risk and may thus be vaccinated for HZ.

Incidence and risk factors for herpes zoster in patients with rheumatoid arthritis receiving upadacitinib: a pooled analysis of six phase III clinical trials

BackgroundUpadacitinib (UPA) is an oral Janus kinase (JAK) inhibitor approved for the treatment of rheumatoid arthritis (RA). JAK inhibitors have been associated with an increased risk of herpes zoster (HZ)...

Risk of herpes zoster in patients with rheumatoid arthritis in the biologics era from 2011 to 2015 and its association with methotrexate, biologics, and corticosteroids.

To elucidate the incidence and risk factors of herpes zoster (HZ) in patients with rheumatoid arthritis (RA) in the biologics era. We determined the rate of HZ occurrence among the RA patients that participated in the Institute of Rheumatology, Rheumatoid Arthritis surveys from 2011 to 2015, by assessing medical records. The standardised incidence rate per 1000 patient-years with a 95% confidence interval (CI) was calculated, and risk factors for HZ were analysed using a time-dependent Cox regression analysis. Among 7815 patients (female, 84.7%) contributing to 25,863 patient-years of observation, 340 HZ events in 309 patients were confirmed. The standardised incidence rate (95% CI) per 1000 patient-years was 8.5 (6.9-10.5) in total, 6.0 (3.7-9.2) in men, and 11.0 (8.7-13.7) in women. Risk factors for HZ were age per 10 years (hazard ratio 1.14, 95% CI 1.03-1.26, p < .05), Japanese version of the Health Assessment Questionnaire (J-HAQ) score of 0.5-1.5 (versus J-HAQ = 0; 1.51, 1.09-2.10, p < .05), methotrexate use (1.58, 1.06-2.36, p < .05), and biologic use (1.88, 1.44-2.47, p < .01). In the era when biologics were frequently used and corticosteroid use and doses were decreasing, methotrexate and biologics increased the risk for HZ.

Risk Factors for Herpes Zoster in Patients with Chronic Kidney Disease: A Case-Control Study.

(1) Background: Chronic kidney disease (CKD) increases the susceptibility to the presence of herpes zoster (HZ). Little is known about the risk factors of HZ in CKD patients; (2) Methods: This is a case-control study. CKD patients diagnosed with HZ between January 2015 and June 2021 in a tertiary hospital were identified. One age- and gender- matched control was paired for each case, matched to the date of initial HZ diagnosis. Conditional multiple logistic regression was used to evaluate the risk factors associated with the presence of HZ; (3) Results: Forty-seven HZ patients and controls were identified. In general, about 73.40% (69 out of 94) patients were classified at IV to V stages of CKD. Immunosuppressive agents (p = 0.0012) and dialysis therapy (p = 0.021) were reported more frequently in the HZ cohort. Compared with the control group, the total white cell count and lymphocyte count were significantly lower in the HZ group (p value of 0.032 and 0.003, respectively). The conditional logistics regression model revealed that previous immunosuppressants administration (odds ratio: 10.861, 95% CI: 2.092~56.392, p = 0.005) and dialysis therapy (odds ratio: 3.293, 95% CI: 1.047~10.355, p = 0.041) were independent risk factors of HZ in the CKD population; (4) Conclusions: Dialysis and immunosuppressants therapy were associated with greater risk of HZ disease in CKD patients. Further guideline may highlight the necessity of zoster vaccine for patients with CKD, who undertake associated treatment.

Hypertension and dyslipidemia are risk factors for herpes zoster in patients with rheumatoid arthritis: a retrospective analysis using a medical information database

This study used data from a large-scale multicenter medical information database in Japan to estimate the incidence rate of herpes zoster (HZ) and to examine the relationship between hypertension, dyslipidemia, and diabetes mellitus (DM), and the risk of HZ among patients with rheumatoid arthritis (RA). The research dataset consisted of 221,196 records of potential target patients with RA extracted between April 1, 2008 and August 31, 2017 from the Medical Data Vision database. To assess the association between hypertension, dyslipidemia, and DM and the risk of HZ, a case–control study was set up. Records of 101,498 study subjects met the inclusion criteria. During the observation period, 2566 patients developed HZ and the overall incidence rate was 5.2 (95% confidence interval: 5.0–5.4 per 1000 patient-years). Hypertension, dyslipidemia, and DM were significantly associated with an increased risk of HZ after adjustment for sex, age, hospital size, and use of anti-rheumatic drugs. When mutual adjustment was made for hypertension, dyslipidemia, and DM, the positive associations between hypertension and dyslipidemia and the risk of HZ remained significant; however, the positive association with DM completely disappeared. RA patients with hypertension or dyslipidemia may be at higher risk of HZ.

Recurrent Herpes Zoster as a Sign of HIV Infection

Herpes Zoster is characterized with painful dermatomal blisters, which commonly seen in elderly or immuncompromised people. It is caused by varicella zoster virüs (VZV). HIV infection is known as a risk factor for herpes zoster and for developments of its complications. Cutaneous findings can be the presenting symptom for HIV infection. In the presence of HIV infection, HZ can be prolong or can complicate evet its recurrence rate increases. HZ recurrences are usually seen in immuncompromised individuals. In the presence of HIV infection, the risk of HZ increases up to 12-17 fold. Prophylaxis with daily asiclovir decrease the risk of HZ by 68%. Vaccination for HZ was found safe and effective in HIV patients with CD4+ cell count more than 200 cells/. Skin findings are frequent in HIV patients and its diversity change according to the stages of the disease. Here we report a case of recurrent HZ which later diagnosed with positive for HIV, therefore, to mention HIV as a risk factor in cases of recurrent HZ.

The incidence of herpes zoster in patients with diabetes mellitus: A meta-analysis of cohort studies.

The research has correlated the risk factors of herpes zoster with some chronic diseases. This meta-analysis aimed to assess the incidence of herpes zoster in patients with diabetes mellitus.We conducted a literature search using Web of Science and PubMed for articles published from January 1, 2000 to December 31, 2019. The incidence rate ratio and 95% confidence interval for herpes zoster associated with diabetes mellitus was calculated.We included 5 cohort studies for a meta-analysis. The pooled incidences of herpes zoster in patients with diabetes mellitus and in patients without diabetes mellitus were 7.22 and 4.12 per 1000 person-years. The overall risk of developing herpes zoster was significantly higher in patients with diabetes mellitus when compared to those with no diabetes mellitus (incidence rate ratio = 1.60, 95% confidence interval = 1.33–1.93).Patients with diabetes mellitus are substantially at increased risk for the development of herpes zoster. Patients with diabetes mellitus should take into consideration the vaccination to prevent herpes zoster.

Systematic Review and Meta-analysis of Herpes Zoster Vaccine in Patients With CKD

IntroductionChronic kidney disease (CKD) is a risk factor for herpes zoster (HZ) infection. Few studies have examined HZ vaccine (HZV) in this population. We conducted a systematic review and meta-analysis investigating the efficacy and safety of HZV in patients with renal disease (CKD, dialysis, and transplant).MethodsMEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases (up to May 2020) were searched for randomized controlled trials and nonrandomized controlled studies evaluating HZV in patients with CKD for effectiveness and adverse event risks. Studies without a control group (placebo or no vaccine) were excluded. Extraction of prespecified data and risk of bias assessments using the Newcastle-Ottawa scale for cohort studies and the Cochrane Risk of Bias Tool for randomized controlled trials were done by 3 authors. Random-effects meta-analysis was used to generate pooled treatment effects and 95% confidence intervals.ResultsIncluded were 404,561 individuals from 8 studies (3 randomized controlled trials and 5 nonrandomized). All 8 studies examined HZ as an outcome, with 3 reporting adverse events. Risk of HZ was lower in patients who received HZV compared with controls (hazard ratio, 0.55; 95% confidence interval, 0.37–0.82; P < 0.01); however, heterogeneity was high (I2 = 88%, P < 0.01). There was no significant difference in adverse events associated with HZV (hazard ratio, 1.03; 95% confidence interval, 0.54–1.28; P = 0.8).ConclusionsHZV compared with control significantly lowers the risk of HZ without an increase in adverse events in CKD patients. However, significant heterogeneity was present. HZV should be actively considered in CKD patients because the prevalence of HZ is higher in this population.

Analysis of Risk Factors of Herpes Zoster in Patients with Multiple Myeloma Treated with Bortezomib

To explore and analyze the risk factors of herpes zoster in patients with multiple myeloma (MM) during the chemotherapy with bortezomib. Clinical data of 85 MM patients treated with bontizomib from January 2015 to January 2019 were selected and divided into case group and control group accroding to the occurred of herpes zoster. The clinical characteristic, treatment outcome and related factor of herpes zoster were retrospective analyzed. Twenty of the 85 patients with MM treated with bortezomib developed herpes zoster occurred (23.5%). Single-factor analysis showed that age≥65 years, lymphocytopenia occurred before treatment, neutropenia occurred before treatment, ECOG score≥2, application of cyclophosphamide, absence of preventive antiviral therapy were associated with the genesis of herpes zoster (P＜0.05). Multivariate logistic regression analysis showed that lymphocytopenia occurred before treatment, the application of cyclophosphamide and the absence of preventive antiviral therapy were the independent risk factors for herpes zoster (P＜0.05). The incidence of herpes zoster is high in the multiple myeloma patients treated with bortezomib. Lymphocytopenia occurred before treatment, the application of cyclophosphamide, and the absence of prophylactic antiviral therapy are the important risk factors for herpes zoster, for which the clinicians should attach great importance.
