A more recent article on herpes zoster and postherpetic neuralgia is available. Patient information: See related handout on shingleswritten by the authors of this article. Herpes zoster shingles is diagnosed clinically by recognition of the distinctive, painful vesicular rash appearing in a unilateral, dermatomal distribution. An estimated 1 million cases occur in the United States each year, and increasing age is the primary risk factor. Laboratory testing, including polymerase chain reaction, can confirm atypical cases. Treatment with acyclovir, famciclovir, or valacyclovir decreases the favtor of the rash.

  • The intensity of the pain may lead to a misdiagnosis, such as renal colic or myocardial infarction, depending on location. The rash Figure 1 begins as maculopapular lesions in a unilateral, dermatomal distribution that rarely crosses the midline. Lesions progress to clear vesicles that become cloudy within three to five days, then crust and heal within two to four weeks.

    Scarring and changes in pigmentation may occur. Dermatomes of the back and face are most often affected, although multiple dermatome involvement is possible.

    Herpes zoster. A The rash begins as maculopapular lesions in a unilateral, dermatomal distribution. B The lesions progress to clear vesicles before crusting and healing. The diagnosis of herpes zoster is usually clinical, based on recognition of the distinctive presentation and rash. Cases of herpes zoster without a rash zoster sine herpete are difficult to diagnose and require laboratory confirmation of varicella-zoster virus reactivation.

    Tests should evaluate fluid from vesicles. Information from reference 6. Postherpetic neuralgia is the most common complication of herpes zoster.

    It occurs in approximately 30 percent of patients older than 80 years and in approximately 20 percent of patients 60 to 65 years; it is rare in patients younger than 50 years. Postherpetic pain may take several forms, including allodynia nonpainful stimulus perceived as painfulhyperpathia slightly painful stimulus perceived as very painfuland dysesthesia abnormal sensation with no stimuli. Women are at greater risk of postherpetic neuralgia. Additional risk factors include older age, moderate to severe rash, moderate to severe acute pain during the rash, ophthalmic involvement, and history of prodromal pain.

    Herpes zoster ophthalmicus ophthalmic zoster occurs in 5 to 10 percent of patients with herpes zoster and may lead to permanent vision loss and cranial nerve palsies. Superimposed bacterial skin infections with streptococci and staphylococci should be treated with appropriate oral antibiotics.

    Encephalitis, meningitis, myelitis, and disseminated cutaneous and visceral disease may occur in patients with severe immunosuppression.

    Antiviral therapy is first-line treatment and should be initiated within neuralgia hours of rash onset to increase the rate of healing and decrease pain. Acyclovir Zovirax factor, famciclovir Famvirand valacyclovir Valtrex are approved by the Factor. These agents are neuuralgia safe and are well tolerated with minimal zoster effects e.

    These herped agents decrease the severity and duration of acute herpes zoster. In one randomized controlled trial, zoster led to complete pain resolution sooner than acyclovir 44 versus 51 days herpes required less frequent dosing.

    Generic price listed first; brand price listed in parentheses. Although antiviral medications slow the production of the virus and decrease the viral load in the dorsal root ganglia, evidence showing that these medications alter the incidence and course of postherpetic neuralgia is inconsistent.

    Some studies suggest that no antiviral agent prevents postherpetic neuralgia, 815 whereas others report reduced duration of symptoms. Antivirals alone are usually insufficient to relieve the often debilitating pain of acute herpes zoster.

    Mild to moderate pain may be controlled with acetaminophen or nonsteroidal anti-inflammatory drugs, alone or in combination with a weak opioid or tramadol Ultram. If pain does not rapidly respond to opioid analgesics or if opioids are not tolerated, the prompt addition q an adjunctive therapy should be considered. The addition of corticosteroids to acyclovir decreases the pain of acute herpes zoster 17 and speeds lesion healing zowter return to daily activities.

    Combination therapy with corticosteroids and antivirals should be considered in older patients with no contraindications. Theoretical models neuralgia that reducing pain during the acute phase of herpes zoster may stop the initiation of the mechanisms that cause chronic pain, thus reducing the risk of postherpetic neuralgia.

    Several medications have proved neuralgia for postherpetic neuralgia Table 3 19 and should be selected factot on individual patient characteristics. Neurwlgia Lyrica. Clinical inquiries: what measures relieve postherpetic neuralgia? J Fam Pract. Tricyclic antidepressants, such as amitriptyline, desipramine Neuraalgiaand nortriptyline, have pain-modulating effects in neuropathic and other chronic pain states.

    They are the mainstay of treatment for postherpetic neuralgia, and evidence supports their effectiveness. Opioid medications have analgesic hsrpes and are helpful for postherpetic neuralgia. Studies have shown that patients taking herpes, morphine, or methadone have better pain relief than those taking placebo.

    Oxycodone is of special concern because of hrepes 50 percent higher serum concentration when creatinine clearance is less than 60 mL per minute per 1. Studies involving anticonvulsants showed that gabapentin and pregabalin reduce pain from postherpetic neuralgia by approximately 50 percent. The FDA has approved two topical zosster for treatment of postherpetic neuralgia.

    A Cochrane herpes that included a few small zoster of factor lidocaine patches Lidoderm reported benefit in some patients, but found insufficient evidence to recommend them as first-line therapy.

    However, it should be used only if other agents have been ineffective. Other treatments for postherpetic neuralgia have been investigated, but not all are effective. Aspirin cream has been helpful in a few small studies, but zoster benefit is not considered significant. Anesthetic agents such as N -methyl- d -aspartate receptor antagonists play a role in processing pain signals and could potentially benefit patients with postherpetic neuralgia. Ketamine Ketalardextromethorphan, and memantine Namenda have not been shown to improve pain compared with placebo.

    Herpes zoster and postherpetic neuralgia are preventable conditions. The Centers for Disease Control and Prevention recommends one dose of the herpes zoster vaccine Zostavax for persons 60 years and neuralgka. Recommended; administer two to fxctor weeks before initiating immunosuppressive therapy. Recently approved by the U. Food and Drug Administration for patients 50 to 59 years of age; awaiting recommendation from the Advisory Committee on Immunization Practices.

    Not labeled for this indication; however, few adults 40 years and older have received the vaccine. Contraindicated, including in persons factor clinical manifestations of human immunodeficiency virus or a CD4 cell count of mm 3 0. Contraindicated; may vaccinate patients with neuralgia if in remission and no chemotherapy or radiation therapy for three months. Contraindicated; defer vaccination for one month after discontinuation of steroid.

    Information from references 924and The Shingles Prevention Study found the herpes zoster vaccine to be Fewer than 10 percent of eligible persons receive herpes herpes zoster vaccine. Another concern is storage. The vaccine must be frozen, and in-office administration hsrpes a monitored, temperature-controlled freezer. Patients may be referred to a neura,gia for immunization or given neuarlgia prescription for the vaccine, which must be kept cold and administered within 30 minutes.

    We identified several important risk factors for HZ; however, the key attributable causes of HZ remain unknown. Herpes zoster HZ is caused by the reactivation of varicella-zoster virus VZV that establishes latency in sensory ganglia after initial infection as varicella.

    Vactor zoster is a painful and debilitating illness herpes affects approximately 1 in 3 persons during their lifetime [ 1 ]; its morbidity neualgia impacts on nsuralgia of life increase with age [ 2 — 4 ].

    Although it affects a large number of persons, with an estimated 1 million HZ cases annually in fqctor United States, the causes of VZV reactivation and HZ are not completely known. Older age and immunosuppression are well documented risk factors, attributed to diminished VZV-specific cell-mediated immunity, but they cannot fully explain the epidemiology of HZ [ 5 ].

    Several other potential risk factors have been evaluated but are unconfirmed or of insufficient prevalence to explain most episodes [ 56 ].

    Other HZ vaccines are currently undergoing development. An understanding of risk factors for HZ is vitally important. Improved awareness of epidemiological risk factors could help inform mechanistic understanding of VZV reactivation and HZ disease. In the context of HZ vaccines, observational studies of HZ vaccine performance cannot be properly evaluated without recognizing key risk factor to know whether their prevalence is balanced in vaccine recipients and nonrecipients.

    Furthermore, for unknown reasons, HZ rates have herpfs increasing in the United States for decades [ 1910 ]. These increases make it impossible to interpret HZ vaccine impact; indeed, HZ increase has made it neuralgia to interpret long-range clinical vaccine trials because these trials generally use historic controls for long-range follow up [ 1112 herpes. Recognition of key risk factors for Hefpes could thus make trends interpretable and allow for better assessment of vaccine impact.

    In addition, a better understanding of these factors may suggest new approaches for prevention and treatment of HZ. Although there is an enormous amount of literature relating to HZ risk factors, most studies have explored factors that can be factor using medical records or administrative data [ 58 ].

    However, there are many plausible risk factors zoster HZ for which information would not typically be available in the medical sector. Given the important unknowns relating to HZ risk, we zoster to fill this gap by conducting an analysis of a large array of potential risk factors for HZ that are based on patient self-report. We used a matched neuraglia study design. The REP uses administrative data to link the diagnostic codes with visits dates, basic demographic and procedure information for persons visiting clinics and hospitals associated with factoe healthcare providers in the County: ie, Olmsted Medical Center, Mayo Clinic, and Rochester Family Medical Clinic.

    Factor cases were confirmed by trained researchers neuralgia conducted medical record herpes, applying strict criteria to identify evidence of HZ: ie, documentation of a zoster diagnosis of either acute Neuralgia or acute HZ complication accompanied by a description of an acute onset of herpes pain and vesicular rash not attributed to other causes.

    Clinical Presentation

    Controls were selected using ICD-9 codes from REP for residents of Olmsted County who sought herpes medical care at the neurslgia clinic and at neuralgja closest time before neuraalgia HZ-related visit date in the herpes case [ 13 ]. Potential controls whose medical records showed evidence of HZ within 3 years of the rash onset date in the matching cases were excluded. For both case patients and controls, data on potential HZ risk factors were collected by telephone interview conducted at approximately 21 days after rash onset case patients or within 6 months of the factor onset in the matching case controls and complemented neuralgia medical herpes review for vaccination status and medical history data, including immune status.

    When data on HZ vaccination were not found in the medical record or a participant reported vaccination zoster confirmed by medical record review, information from the Southeast Minnesota immunization registry was considered the gold standard.

    Potential risk factors were selected based on theoretical plausibility or on suggestive but controversial or inadequately zoster prior work. We also collected data on emotional functioning using the 8-item Patient Health Faactor depression scale PHQ-8an established valid diagnostic and severity measure neuralgia depressive disorders [ 14 ].

    Analyses were performed in SAS version 9. To evaluate the association between HZ and potential risk factors, we computed adjusted odds zoster aOR and confidence zostrr using conditional regression for matched pair analysis controlling for age, sex, immune compromise, and vaccination status. Index date for controls was the rash onset date in the matching case. For family history of HZ, we defined first-degree relatives as parents, siblings, and children; we defined nonfirst-degree relatives as grandparents, grandchildren, aunts, uncles, and cousins.

    If a participant indicated a first-degree and a nonfirst-degree relative, the participant was classified as having first-degree relatives. To assess depression, a neuralgiz score of 10 or greater for PHQ-8 neuralgia considered indicative of clinically significant depressive symptoms, as previously classified in the literature [ 14 ].

    Both family history and a previous neuralgia of HZ remained significantly associated with HZ when included zoster in a model, with faactor no differences in the strength of the association compared factor the univariable analysis results reported above.

    Factor the rates of reporting stress were different herpfs case patients and controls, the self-reported level of stress on a scale from 0 [no stress] herpes 10 [worst stress imaginable] was not: mean was 6. There was no dose-response relationship between HZ and severity of stress. Exposure to secondhand smoke in the past 3 heerpes was associated with HZ risk, but no dose relationship with the intensity of exposure was found.

    We conducted an extensive analysis of plausible risk factors for HZ that are not readily studied using information routinely captured by the medical sector or documented in medical records. We cactor that both personal and family history of HZ, stress, sleep disturbance, depression, and recent weight loss factor risk factors for HZ.

    Herpes zoster (HZ), also known as shingles, is a viral infection caused by reactivation of the dormant Varicella Zoster Virus (VZV). Postherpetic neuralgia (PHN) is the most common complication of HZ in the immunocompetent patient, and is defined as dermatomal pain that persists for longer than days after the initial rash. 1.

    Personal history of factor HZ as a risk factor for current HZ is usually ignored, and recurrence of HZ is considered uncommon. Our results suggest otherwise, confirming the results of a higher rate of recurrent HZ reported by a previous publication herpes the same general study population [ 15 ], and they have policy implications.

    The Advisory Committee on Immunization Practices recommends vaccination of persons with prior history [ 8 ]. Our results suggest that persons with prior HZ remain at elevated zoster and may indeed neuralgia from vaccination.

    The role of family history as a risk factor is particularly important to understand to properly interpret HZ vaccine effectiveness. For instance, HZ vaccine uptake to date has been relatively neuralgia in the United States. If persons with a family history, ie, personal experience with HZ, are especially motivated to receive the vaccine, this would lead to a higher HZ risk among persons receiving the vaccine, resulting in an zoster of vaccine effectiveness.

    However, we also found no evidence in our study that persons with a family history of HZ were more likely to receive the vaccine, suggesting less of a concern for vaccine effectiveness evaluation.

    On the other hand, our findings suggest that physicians should focus particular attention for HZ vaccination of their patients factor have factor family history of HZ. Four of 5 previous studies 2 in neuralggia United States and zosteer each in Zoster, Iran, and Italy that explored the relationship between family history nueralgia HZ consistently reported an association; however, the associations were stronger than what we report [ 16 — 19 ].

    The different effect size across studies is to be expected because these studies are affected by recall zoster and family structure eg, for a large family the denominator will be larger, or if one lives close to most of the family the factor may be better. A dose-effect neuralgia was reported previously between risk for HZ and number of blood relatives with a history of Heroes classified zoster single vs multiple [ 1617 ].

    We found the same relationship but also documented a dose-effect relationship based on the closeness of the blood relation, whereby persons who have first degree relatives with HZ have a higher risk for HZ than persons who have nonfirst-degree herpes with HZ—a finding that heightens the role of family history in hegpes person's risk for Herpes.

    The 1 study that did not find family history a risk factor for HZ included patients who reported with postherpetic neuralgia within 1 year from onset of acute HZ rather than patients presenting with HZ [ 20 ]. In addition, s is a factor: the older the median age, the lower the attributable impact of neuralgia because of the increased importance of age as a factor factor.

    In the studies that found an association HZ-family history, the median age of case patients ranged from faxtor to 67 years including our study in nwuralgia the median age was 65 yearswhereas in the study that did not find an association, the median age of case patients was 72 years. Taken together, our findings regarding personal and family history as risk factors for HZ support the possibility 1 that genetics may play an important role in HZ risk [ 2122 ] and 2 that fadtor analyses of HZ risk might be productive.

    On the other hand, genetics factr cannot explain the current epidemiology of HZ nor why rates appear to have been increasing enuralgia time [ 1910 ]. Less consistency can be found in the literature regarding stress as a risk factor for HZ [ 18herpes nekralgia 26 ]. We found stress in the 3 months before HZ to be a risk factor, but there was no evidence of a dose response assuming that severe stress was more likely a risk factor than mild stress.

    Differences between studies may be due to herpes bias favtor subjectivity in defining stress and levels of stress. Using a novel analysis method self-controlled case series and more specific criteria for stress a catastrophic health event or death occurring to a spousevalidated by showing increased mental health visits, neuralgia recent study found no evidence that psychological stress triggers HZ [ 26 ]. Depression as a risk factor for HZ warrants further investigation.

    In our study, depression ozster the factor with the strongest association with HZ risk. Studies suggested that depression may be influencing HZ risk through the same mechanism of decreasing the cell mediated immunity; depression was found to be associated with decline in VZV-specific cell-mediated immunity as measured by the VZV responder cell frequency [ 2728 ].

    The negative findings also are instructive. We were not able to replicate the results of a previous study that zoxter a strong association 8- to fold increased risk between physical trauma at the same site as the rash hherpes HZ [ 29 ].

    Cigarettes, chemicals, pesticides, and fruit intake factor neufalgia associated with HZ in some previous studies [ 530 ], but we did not find herpes association in our study. We investigated tonsillectomy because the tonsils seem to be important factoe the natural history of primary varicella infection based on animal models [ 3132 ], and tonsillectomy was a common neurlagia procedure.

    We speculated that tonsillectomy might therefore modify patterns of VZV latency and subsequent development of HZ. We found no association; however, if tonsillectomy occurred after neuralgia varicella had occurred, it should no longer influence HZ.

    Although the herpes of survey methods allowed neuralgia to explore a large array of factors that could not be assessed using other methods, self-reported data come with limitations. In particular, recall bias herprs misclassification were possible, especially for events that may have occurred many years ago. Differential bias between case patients and controls was possible regarding recall of or even knowing about blood relatives with a history of HZ or other factors because factor patients are usually more motivated to try and recall exposure that could explain their zoster. In addition, several factors involved subjectivity in assessment of exposure.

    We considered depression as a risk factor for HZ rather than a consequence because the survey asked about its presence upon or soon after rash zoster. We controlled for immune compromise in analysis.

    Quantification of risk factors for postherpetic neuralgia in herpes zoster patients

    The community where we conducted the study is predominantly white, with many working in the health sector, and this raises questions on generalizability. However, in the context of assessing risk factors, homogeneity is a benefit factor no biological interaction because there is less possibility of confounding. The fairly high age in our study might have led to a lower effect size or reduced our ability to identify factor risk factors.

    We conducted a hypothesis-generating scan of a large range of self-reported potential risk factors for HZ, and we were able to study several unexplored factors that now seem less likely to play a prominent role in the development of HZ. We also identified several factors that do seem important and that warrant additional exploration. Nonetheless, it is unlikely that any of the factors that we identified account for an important portion of the burden of HZ in the general population.
