Herpes Zoster oftálmico e posterior acidente vascular cerebral: relato de caso

A sixty-nine year old man suffered a stroke fourteen weeks after the onset of right herpes zoster ophthalmicus (HZO). Hemispheric infarction was documented by a computed tomography which showed a small hypodense zone in the right internal capsula; after contrast there was enhancement of this hypodense area. Cerebral angiography and cerebral-spinal fluid were not done. Despite of a diagnosis of probability the authors report the case and review the literature. A long latency between the HZO and onset of neurological deficit is stressed. New antiviral agents may prevent the ictus.

Incidence, Risk Factors, and Outcome of Herpes Zoster in Systemic Lupus Erythematosus

Background: The incidence and outcome of Herpes zoster (HZ) in systemic lupus erythematosus (SLE) are not completely defined as well as the relevance to HZ of disease and therapy factors. Objective: To determine HZ features in SLE. Patients and Methods: SLE patients ( 1997 update of the American College of Rheumatology classification criteria) with definitive HZ infection were identified from our Lupus Clinic computerized database of 1145 patients. Results: HZ was diagnosed in 51 SLE patients (4.45%) with an annual incidence rate of 6.4 events/1000 patient-years. At HZ diagnosis, mean disease duration was 9.78 +/- 8.37 years, median Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) was 1, and only 17.6% had SLEDAI >= 8. Frequency of manifestations and immunosuppressor use were similar between patients with and without HZ. Forty-two patients (82.5%) with HZ were under prednisone with concomitant immunosuppressive therapy in 66.7%. Thirty-five patients (68.6%) were using immunosuppressors: azathioprine (39.2%), cyclophosphamide (9.8%), and mycophenolate mofetil ( 9.8%). The mean lymphocyte count was 1219 +/- 803/mm(3) (43.1% < 1000/mm(3) and 17.6% < 500/mm(3)). Only patients using azathioprine and cyclophosphamide had lymphocyte counts < 500/mm(3) (15% and 40%). All patients received acyclovir, 19.6% had postherpetic neuralgia, and recurrence occurred in only 7.8%. Thoracic nerves were the most involved site (56.8%) followed by lumbar (23.5%). Bacterial suprainfection occurred in 11.7% but was not associated with therapy, lymphocyte count, or SLEDAI scores ( P > 0.05). Conclusion: This is the largest cohort to determine that HZ is a late SLE complication with some peculiar features, such as good prognosis and typical dermatomal distribution. In addition, we have identified that the major trigger factor for this viral infection in SLE is therapy, particularly the concomitant use of corticosteroid and immunosuppressors, and not active disease.

Soropositividade para HIV em doentes de herpes zoster

Os autores estudam a relação de zoster com soropositividade para HIV. Foram testados soros de 66 pacientes (31 homens e 35 mulheres) com quadro agudo de zoster, usando-se o método de ELISA para detectar anticorpos anti-HIV. Não houve seleção dos pacientes, evitando assim lidar com amostra viciada. Entre os 7 HIV +, 6 pertenciam a grupo de risco para AIDS, todos eram do sexo masculino e seis tinham idade entre 19 e 39 anos (idade média de 31,7 anos). Os resultados sugerem que o diagnóstico de herpes zoster em pacientes jovens não se vincule necessariamente à infecção pelo HIV. Quando, no entanto, o doente pertence a grupo de risco para AIDS, independentemente de sua idade, existe associação estatisticamente significativa, tornando-se imperativa a pesquisa de anticorpos anti-HIV.

Herpes Zoster na Infância

O herpes zoster (HZ) surge por reactivação do vírus varicella zoster, latente na raiz dorsal dos gânglios sensoriais. A incidência aumenta com a idade, sendo raro na infância. São descritos os casos de duas crianças de dez e 16 meses,previamente saudáveis, internadas por exantema vesicular localizado, respectivamente, aos dermátomos T11-T12 e ramo oftálmico do trigémio. Foram medicadas com aciclovir com boa evolução e o estudo da imunidade efectuado não apresentava alterações. A aquisição precoce de HZ é rara e tem sido atribuída à imaturidade do sistema imunitário da criança e à interferência com os anticorpos maternos. Numa criança pequena, previamente saudável, o HZ é um diagnóstico possível e a exclusão de imunodeficiência subjacente não é obrigatória.

Abdominal wall protrusion following herpes zoster

We present the case of a 62-year-old woman with abdominal segmental paresis consequent to radiculopathy caused by zoster, which was confirmed by electroneuromyography. The paresis resolved completely within three months. Recognition of this complication caused by zoster, which is easily misdiagnosed as abdominal herniation, is important for diagnosing this self-limited condition and avoiding unnecessary procedures.

Pseudo-myocardial infarction during an episode of herpes zoster

The patient arrived at the emergency unit with a history of acute myocardial infarction, for which she was treated. Without improvement in the pain, the patient developed heart failure and underwent a hemodynamic study, which showed normal coronary arteries and extensive ventricular impairment. During evolution, the clinical findings improved and herpes zoster appeared on the right shoulder. In a few months the clinical findings subsided, and the findings of the electrocardiogram, chest X-ray, and ventricular function were normal. The patient is currently asymptomatic.

Incidence and clinical characteristics of herpes zoster after lung transplantation.

BACKGROUND: Solid-organ transplant recipients are at high risk for the development of herpes zoster. Epidemiologic data in lung transplant recipients are lacking. We determined the incidence and clinical characteristics of herpes zoster, and the risk factors for developing herpes zoster, after lung transplantation. METHODS: We retrospectively reviewed all adult (&gt;18 years old) lung transplants performed at our institution between January 2001 and December 2005. Clinical characteristics of herpes zoster and potential risk factors associated with herpes zoster were assessed. RESULTS: Two hundred thirty-nine lung transplant recipients were included in the analysis. Median time of follow-up was 722 days (range 18 to 1,943 days). Thirty-five episodes of herpes zoster occurred in 29 patients, with a calculated incidence of 55.1 cases per 1,000 person-years of follow-up. The cumulative probability of herpes zoster was 5.8% at 1 year, 18.1% at 3 years and 20.2% at 5 years post-transplant. Only 2 of the 35 (5.7%) patients had disseminated cutaneous infection and none had visceral involvement. Recurrence of herpes zoster was seen in 13.8% of patients. Post-herpetic neuralgia was detected in 20% of cases. Anti-viral prophylaxis, primarily for cytomegalovirus (CMV), was protective against herpes zoster. No significant epidemiologic risk factors associated with herpes zoster could be identified. CONCLUSIONS: Herpes zoster is a common complication after lung transplantation with a peak incidence at between 1 and 4 years post-transplant. Preventive strategies would be beneficial for this population.
