Zoster sine herpete después de infección leve por SARS-CoV-2 / Zoster sine herpete after mild SARS-CoV-2 infection

El SARS-CoV-2 es un virus de afectación sistémica que impacta con gran intensidad en el sistema inmunológico; esto permite que virus de naturaleza latente, como el virus de Varicela Zoster (VVZ), tengan oportunidad de reactivarse y agravar el cuadro respiratorio con afectaciones cutáneas, mucosas y neurológicas. Se presenta un caso de Zoster sine herpete, durante la convalecencia del SARS-CoV-2, en un paciente masculino de 43 años, que acudió a consulta por dolor precordial de gran intensidad, sensación de escozor en tórax posterior y dificultad respiratoria; 10 días después de prueba de hisopado nasofaríngeo positiva para antígeno de SARS-CoV-2. Es importante no olvidar la probabilidad de presentaciones atípicas de virus latentes con el fin de realizar un diagnóstico y tratamiento oportuno a los pacientes.

SARS-CoV-2 is a systemic virus that has a strong impact on the immune system; this allows latent viruses, such as varicella-zoster virus (VZV), to reactivate and aggravate the respiratory symptoms with cutaneous, mucosal and neurological involvement. We present a case of Zoster sine herpete, during convalescence from SARS-CoV-2, in a 43-year-old male patient who presented with severe precordial pain, stinging sensation in the posterior thorax and respiratory distress; 10 days after a positive nasopharyngeal swab test for SARS-CoV-2 antigen. It is important not to forget the probability of atypical presentations of latent viruses to make a timely diagnosis and treatment of patients.

Diverse clinical manifestations caused by varicella-zoster virus reactivation / 영남의대학술지

The two distinctive clinical features of varicella-zoster virus (VZV) are varicella (chickenpox) by primary infection and zoster (singles) by the reactivation of latent infection. In addition to the two typical clinical symptoms mentioned above, diverse clinical manifestations have been reported as a result of VZV reactivation, including chronic radicular pain without rash, visual loss, facial palsy, dysphagia, sore throat, odynophagia, otalgia, hearing loss, dizziness, headache, hemiplegia, etc. Most of these symptoms are derived from neuropathy and vasculopathy of affected nerves and arteries. Diagnosis of VZV disease can be difficult if there is no appearance of a skin rash during development of atypical symptoms. In addition to natural infection, vaccination and anti-viral agent treatment have influenced the changes of epidemics and clinical presentations of varicella and zoster. In this article, diverse clinical manifestations caused by VZV reactivation, particular without skin rash, are reviewed.

Parálisis Parcial del Nervio Oculomotor Secundaria a Zoster Sine Herpete: Reporte de Un Caso / Partial Palsy of the Oculomotor Nerve Due to Zoster Sine Herpete: A Case Report

Introducción: Herpes Zoster es la reactivación del Virus Varicela Zóster en los ganglios sensoriales y/o autonómicos, típicamente caracterizado por dolor profundo de distribución dermatómica y erupciones vesiculares en piel. De manera infrecuente, puede presentarse el Zoster Sine Herpete, condición en la cual se presenta la distribución dermatómica del dolor en ausencia de lesiones dérmicas, convirtiendo el diagnóstico en un reto clínico. Caso clínico: Hombre de 69 años con dolor periorbitario, epifora, ptosis y pérdida de la aducción del ojo derecho. Los estudios imagenológicos y de laboratorio fueron normales, descartando así las principales causas de parálisis del nervio oculomotor. Se hizo diagnóstico presuntivo de Zoster Sine Herpete y se inició prueba terapéutica con valaciclovir, observándose resolución total de la sintomatología seis semanas después. Discusión: Este caso puede ser el primero en describir una parálisis parcial dolorosa del nervio oculomotor como única manifestación clínica de la reactivación del Virus Varicela Zóster y busca alertar al personal médico sobre una enfermedad latente que hace de sus reapariciones una gama de presentaciones no siempre fáciles de identificar.

Introduction: Herpes zoster is the reactivation of the varicella zoster virus in the sensorial and/ or autonomic ganglia, typically characterized by cutaneous vesicular eruptions and deep pain with dermatomal distribution. Infrequently can occur the Zoster Sine Herpete; condition in which there is dermatomal distribution of the pain in absence of dermic injuries, making the diagnosis a challenge for the clinician. Case report: 69 years old man with periorbital pain, epiphora, ptosis and loss of adduction of the right eye. The imaging and laboratory studies were normal, excluding with this the main causes of oculomotor nerve palsy. A presumptive diagnosis of Zoster Sine Herpete was done and a therapeutic test with valacyclovir was initiated, showing complete resolution 6 weeks later without sequelaes. Discussion: This case may be the first in describing partial painful oculomotor nerve palsy as the only manifestation of the varicella zoster virus reactivation and seeks to aware the medical staff about a latent disease that makes from his reappearances a wide range of presentations not always easily to identify.

Spinal Arteriovenous Malformation Masquerating Zoster Sine Herpete

Zoster sine herpete (ZSH) is difficult to diagnosis during an acute period due to the absence of the characteristic zosteriform dermatomal rash; therefore, progression to postherpetic neuralgia is more common than typical zoster. In addition, misdiagnosis of other neuropathic pain as ZSH is common in clinical situations. Here, we report a case of spinal arteriovenous malformation that mimics ZSH. This is a rare condition; therefore, high clinical suspicion for a correct diagnosis and proper examination are not easy. However, early diagnosis and definitive treatment are essential to prevent neurologic deficit and mortality.

Herpes Sine Zoster: Is the Cause for the Segmental Intercostal Neuralgia of Unknown Cause?: A case report / 대한통증학회지

Zoster sine herpete (ZSH) is a varicella zoster virus (VZV) reactivation without a zoster that is difficult to diagnose early after onset. This study examined 12 patients who presented with intercostal neuralgia, had no history of trauma, cutaneous eruption and no scar of a herpes zoster on the lesion. Two patients had a vertebral compression fracture. Two patients had a history of a zoster in the other site. No other suspicious findings were observed. Ten of the twelve patients were checked for the IgG and IgM varicellar zoster virus antibody. All the patients tested positive to the Ig G antibody test and only one patient tested positive to the IgM antibody test. One patient was confirmed to have ZSH and the other patients were suspected of having ZSH. All the patients were treated for postherpetic neuralgia, resulting in a significant decrease in the intercostal neuralgia.

Ramsay Hunt Syndrome during the Treatment of Zoster Sine Herpete / 대한마취과학회지

Ramsay Hunt syndrome (RHS) might cause serious complications, such as facial paralysis and hearing loss if diagnosis and treatments are delayed. Early diagnosis is therefore very important to avoid such serious complications. We report a case of RHS that was occurred during the treatment of postherpetic neuralgia resulted from zoster sine herpete. The patient showed severe segmental intercostal neuralgia at the right 11 and 12th thoracic level. There were no history of the trauma, operation and skin rash and vesicle on the lesion site. Varicellar-zoster virus (VZV) IgG Antibody was positive but VZV IgM antibody was negative. Pain nature was severe sharp, electrical shock like pain, but no paresthesia and dysesthesia was not existed. About two month later, small painful vesicular eruptions were occurred around the ipsilateral auricle. At this time, VZV IgM antibody was positive. Acyclovir, prednisolone, fexofenadine were immediately prescribed. The patient relieved from RHS without any complications. Clinician should be suspect the possibility of zoster sine herpete if the patient showed severe atypical chest wall pain.

A Case of Herpes Zoster Sine Herpete following Pediatric Penetrating Keratoplasty

Herpes zoster ophthalmicus sine herpete(HZSH), which means herpes zoster ophthalmicus(HZO)without skin eruption, is one of the atypical manifestations of varicella-oster virus(VZV)infection. Idiopathic iridocyclitis or acute retinal necrosis without skin lesion secondary to varicella-oster virus are good examples. Diagnosing zoster iridocyclitis without skin eruption is difficult because in the absence of typical skin eruption it is difficult to suspect varicella-zoster virus as the cause of inflammation in the absence of typical skin eruption. We describe here a rare case of a pediatric patient with severe iridocyclitis in a pediatric patient after penetration of keratoplasty in whom VZV DNA was detected using the DNA amplification and polymerase chain reaction(PCR)method. To our best knowledge, this is the first case report of varicella-zoster virus iridocyclitis in a pediatric patient after penetrating keratoplasty.
