Herpes zoster occurred with high frequency in patients with PM-DM. The clinical courses of zoster infections were uneventful; no severe complications nor deaths occurred, and only one patient had postherapeutic neuralgia. No specific therapy for this infection was necessary. Zoster tended to occur in the inactive stage of PM-DM. PM-DM patients with herpes zoster had a significantly higher incidence of antinuclear antibody. There seemed to be no relationship between steroid therapy and herpes zoster infection. Introduction PM-DMare diffuse inflammatory diseases of the striated muscle wich may lead to muscle atrophy and proximal muscle weakness involving the limb, pharynx, face and neck. The etiology of PM-DM is an autoimmune disease mediated lymphocytes' and that some patiets have humoral immuodeficiency2).Such patients have a susceptibility to infections, and corticosteroid therapy may lead to further reduction in host defence to infection3). Herpes zoster, an inflammatory human disease by the varicella-zoster virus, is characterized by papulovesicular along several dermatomes. The varicella-zoster virus may produce varicella as a primary infection and herpes zoster as a secondary infection. Zoster represents reactivation of latent varicellazoster virus that has remained dormant in the dorsal root ganglia, the activation being caused by aging, radiation, immunosuppressive agents and so on4).In addition, this infection appears to be more frequent in certain immunocompromised patients5). In the present study, the clinical characteristics of herpes zoster infections in patients with PM-DM are retrospectively analyzed. In addition, we examined possible predisposing factors of zoster infections in these patients. Materials and Method Subjects The clinical records of all patients with a diagnosis of polymyositis or dermatomyositis from the First Department of Internal Medicine, Yokohama City University Hospital during the interval 1973 through 1983 were reviewed retrospectively and certain features were critically evaluated: Twenty-two patients 別刷 請 求 先: (〒232)横 浜 市 南 区浦 舟 町3-46 横浜 市 立 大学 医 学 部第1内 科 谷 賢治 感 染 症 学 雑誌 第64巻 第11号 Herpes Zoster and PM-DM 1395 who had no family history of myopathy and who fulfilled the Bohan's criteria were selected6).Twenty cases of non Hodgkin's lymphoma and twenty-two cases of SLE in whom age of patients was matched to it of PM-DM patients, were studied as a disease control (Table 1). The American Rheumatism Association criteria were used for selecting patients with SLE7).All patiens with these diagnosis were seen by authors. The diagnosis of herpes zoster was accepted if varicella-zoster virus was isolated from skin lesions. In those ptients with absence of viral cultures, seologic tests, i.e. herpes zoster titer in the serum increasing more than 4 times, were done on these patients to support the conclusion of the diagnosis. Laboratory testsAntinuclear antibody was measured using an indirect immunofluorescent technique') and rat liver as substrate. A reaction was considered positive at a titre of 1:20 or greater. Anti-DNAantibodies were measured using a DNA binding technique. Herpes zoster titer in the serum was measured using the method described elsewhere1°). Statistical analysis Correlation between herpes zoster and other features in patients with PM-DM studied retrospectively were evaluated using t test. Results Incidence of Herpes Zoster in Patients with Polymyositisand Dermatomyositis Five of the 22 patients with PM-DM (22.7%)had a history of herpes zoster infection during 180.4 observation years. On the other hand, 40.9%of the patients with SLE during 171.6 observation years, 10.0% of those with non Hodgkin's lymphoma developedzoster during observation 56 years (Table 1). The duration of PM-DMin these patients prior to the time of development of herpes zoster varied from eleven to 93 months. All cases tended to have an inactive stage of PM-DM when they had an attack of herpes zoster: 4 patients were an inactive stage of PM-DM at the time of herpes zoster infection and only Table *The two patients Table 平 成 2年11月20日 of PM 2 1 Incidence overlapped Clinical with of Herpes classical Manifestations Zoster in Patients RA or SLE of Herpers with PM-DM . Zoster in 5 Patients with PM-DM 1396 Shohei NAGAOKA et al one had a slight elevation of serum aldolase without clinical muscle manifestations when zoster developed. Clinical Manifestations of Herpes Zoster in Five Patients with PM-DM (Table 2) The dermatomal distributions of herpes zoster were thoracic (3 cases) and lumbosacral area (2 cases). The duration from onset to disappearing of all symptoms of herpes zoster ranged from 10 to 30 days with an average duration of 17.6 days. No patients had multiple episodes. In clinical courses of herpes zoster, there were no severe complications such as disseminated zoster and death. Only one of the five patients had persistent neuralgia of the left Th-10 area at the age 69. Interval to the attack of herpes zoster from the onset to PM-DMranged from 1 to 93 months with an average duration of 38.6 months. Activity changes of myositis by herpes zoster infection were as follows: four patients were inactive and one patient had a slight increase of serum muscular enzyme. These patients did not receive specific therapy for herpes zoster. Relationship between Herpes Zoster Infection and Clinical and Laboratory Manifestations of PM-DM (Table 3) The five patients with herpes zoster infection were compared with the seventeen patients without zoster infection, with regard to difference in sex, age at onset of PM-DM,and frequencies of manifestations of PM-DM(both clinical and laboratory). The sex distribution and mean age at onset of PM-DMwere not significantly different between the two groups. As noted in the Table 3, there was a highly significant difference in the frequencies of antinuclear antibody among the two groups (80.0%versus 17.6%).The patterns of antinuclear antibody in PM-DM patients with herpes zoster were various, speckled and/or homogenous, but its tendency as similar in those patients without zoster. Two of the five PM-DM patients with zoster infection overlapped other collagen disorders. One was overlap RA" and the other with SLE. The two groups showed no significant difference in the frequencies of lung fibrosis, cardiac damage, Table 3 ClinicalFeatures in 22 patients with PM-DM * Statiatically significant difference 1) Herpes zoster infected patients , p<0.01 with PM-DM 2) Herpes zoster no infected patients with PM-DM 感 染 症 学 雑誌 第64巻 第11号 Herpes Table Raynaud's phenomenon, Relationship All patients suppressive The The with mg initial was mg 29.0 of Prednisolone malignancy Infection received (range ranged and and lung Treatment steroid tuberculosis. of PM-DM therapy steroid no therapy.
