A necrotizing retinitis in children is a rare but vision threatening ocular complication of chickenpox. We report a 10-year-old girl who developed chickenpox one month before presenting with panuveitis and necrotizing retinitis. After prompt antiviral treatment, her inflammatory signs were resolved. Early detection and treatment of varicellar zoster-associated necrotizing retinitis after chickenpox can achieve good visual outcome.

Herpes zoster (HZ) causes an often severe and painful rash in older people and may be complicated by prolonged pain (postherpetic neuralgia; PHN) and by dissemination in immune-compromised patients. HZ results from reactivation of latent varicella-zoster virus (VZV) infection, often associated with age-related or other causes of decreased T cell immunity. A live attenuated vaccine boosts this immunity and provides partial protection against HZ, but this decreases with age and declines over 8 years. Areas covered: A new HZ subunit (HZ/su) vaccine combines a key surface VZV glycoprotein (E) with a T cell-boosting adjuvant system (AS01B) and is administered by two intramuscular injections two months apart...

Herpes zoster (HZ) or "shingles" results from a reactivation of the varicella zoster virus (VZV) acquired during primary infection (chickenpox) and surviving in the dorsal root ganglia. In about 20% of cases, a complication occurs, known as post-herpetic neuralgia (PHN). A live attenuated vaccine against VZV is available for the prevention of HZ and subsequent PHN. The present study aims to update an earlier evaluation estimating the cost-effectiveness of the HZ vaccine from a Swiss third party payer perspective...

BACKGROUND AND OBJECTIVES: Allogeneic hematopoietic stem cell transplantation (HSCT) is a routine clinical procedure performed to treat patients with haematological malignancies, primary immune deficiencies or metabolic disorders. Infections during lymphopenia after allogeneic HSCT are associated with high mortality and morbidity. Typical infectious agents are Epstein-Barr virus, cytomegalovirus, herpes simplex virus, varicella-zoster virus and fungi. The study aim was to evaluate whether measurement of the responses of antigen-specific T-cells, recognizing infectious pathogens would correlate to protective functions in the stem cell recipient post-transplant...

OBJECTIVE: Thyroid hormone (TH) has been suggested to control herpes virus gene expression and replication in neurons via epigenetics through its nuclear receptors. It has previously been shown that patients with hypothyroidism are predisposed to herpes zoster (HZ), suggesting that the TH deficiency may be a risk factor for varicella zoster virus (VZV) reactivation. The aim of this study was to test the hypothesis that TH treatment will ameliorate the complication of HZ. METHODS: This study investigated the hypothesis by enquiring into a comprehensive medical database at Kaiser Permanente Southern California (KPSC) to verify whether patients taking TH medication experience a reduction in HZ occurrence...

Ramsay Hunt syndrome (RHS) is a rare, severe complication of varicella-zoster virus reactivation in the geniculate ganglion, characterized by hearing loss, pain, and vesicles in the ear or mouth along with ipsilateral facial palsy. Although it is rare, it is more commonly found with immunodeficiency conditions. We report a case of a 35-year-old human immunodeficiency virus positive male, having CD4+ count of 336/μl, who presented with RHS and had vertigo, painful vesicular eruptions on the right ear and unilateral sensorineural hearing loss...

Ramsay-Hunt syndrome (RHS) is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus (VZV) infection occurs in the geniculate ganglion. Major clinical findings are peripheral facial nerve palsy accompanied by ipsilateral ear pain and erythematous vesicular rash on the external ear (herpes zoster oticus) and in the mouth. Thus, diagnosis of RHS is usually clinical. However, auricular herpetic eruption is not always present, making diagnosis more difficult. This report describes a case of RHS with left facial palsy without skin lesions in 60-year-old woman...

Although acyclovir prophylaxis against varicella zoster virus (VZV) infection for ≥1 year is recommended after allogeneic hematopoietic cell transplantation (HCT), the emergence of acyclovir-resistant viruses and adverse drug effects cannot be ignored. We investigated the cumulative incidence of VZV infection after allogeneic HCT in children receiving a shorter duration of acyclovir prophylaxis than recommended and evaluated the appropriateness of the short duration of acyclovir prophylaxis.Medical records of 217 children who received allogeneic HCT were retrospectively reviewed until a median of 25 months (range = 1-59 months) after HCT...

Herpes zoster is a reactivation of the latent varicella zoster virus. Among the complications of herpes zoster is zoster-associated limb paresis. The clinical and imaging features of patients with zoster-associated limb paresis due to plexopathies (zoster-associated plexopathy) have had limited description in the literature. The Mayo Clinic patient data base was searched by diagnostic code for patients diagnosed with herpes zoster between January 1, 1996, and September 30, 2012. Patients who met the inclusion criteria for zoster-associated limb paresis or herpes zoster with MRIs obtained were reviewed...

Although a varicella-zoster virus (VZV) vaccine has been used for many years, the neuropathy caused by VZV infection is still a major health concern. ORF7 of VZV has been recognized as a neurotropic gene in vivo, but its neurovirulent role remains unclear. In the present study, we investigated the effect of ORF7 deletion on VZV replication cycle at virus entry, genome replication, gene expression, capsid assembly and cytoplasmic envelopment, and transcellular transmission in differentiated neural progenitor cells (dNPCs) and neuroblastoma SH-SY5Y (dSY5Y) cells...

Post-licensure surveillance for adverse events following immunizations (AEFI) can identify rare complications of vaccinations and rigorous vaccine adverse event causality assessments can help to identify possible causal relationships. We report the development of arm paralysis after varicella vaccination in a 1-year-old child. Paralysis was initially presumed to be due to vOka because of the temporal relationship between vaccination and onset of arm weakness; however, molecular studies identified wild-type varicella zoster virus VZV (WT-VZV) in the CSF, leading the authors to conclude that WT-VZV was the probable cause...

INTRODUCTION: Gastrointestinal complications are common after renal transplantation, including oral lesions, esophagitis, gastritis, diarrhea, and colon carcinoma. The differential diagnosis is difficult in this scenario because multiple factors such as drugs, infections, and preexisting gastrointestinal disease come into play. CASE PRESENTATION: We report a case of varicella zoster virus-induced pancreatitis and hepatitis in a renal transplant recipient. The patient underwent renal transplantation 3 years earlier and now presented with severe pain in the epigastrium radiating to his back and had raised serum lipase levels and skin lesions characteristic of varicella...

Varicella vaccines are highly effective at preventing disease, but varicella may occur among vaccinated persons (termed breakthrough varicella). Breakthrough varicella is generally mild, but severe cases have been reported. The objective of this review is to describe severe breakthrough varicella. Areas covered: We conducted a systematic review of articles published during 1974-2016. A total of 34 articles were included in our review: 21 described breakthrough varicella with disseminated varicella-zoster virus (VZV) infection with other organ involvement in addition to skin (none among two-dose vaccinees); 9 described hospitalized breakthrough varicella without mention of other organ involvement in addition to skin (of which 2 reported 4 two-dose vaccinees); and 4 described both...

BACKGROUND: Immunocompromised patients can experience significant morbidity and occasional mortality from complications associated with herpes zoster (HZ), but live attenuated HZ vaccine is contraindicated for these patients. Inactivated zoster vaccine (ZVIN) is in development for prevention of HZ in immunocompromised patients. However, there are limited data in the literature regarding the effect of anti-CD20 monoclonal antibodies on vaccine-related cell-mediated immune response. This study evaluated safety and immunogenicity of ZVIN in patients with hematologic malignancies (HM) receiving anti-CD20 monoclonal antibodies (alone or in combination chemotherapy regimens) and not likely to undergo hematopoietic cell transplant (HCT) (n=80)...

BACKGROUND: Acyclovir has been widely used to treat infections caused by herpes simplex virus (HSV) and varicella zoster virus (VZV). The common adverse effects of this drug include nausea, diarrhea, headache, dizziness and mental changes. The immune thrombocytopenia induced by acyclovir is rare. CASE PRESENTATION: A 67-year-old Chinese male who was given acyclovir 5 mg kg(-1) 8 hourly intravenously for treatment of VZV infection developed severe thrombocytopenia with fist sign in oral cavity within 10 days of starting using acyclovir...

Human immunodeficiency virus (HIV)-1 directly affects the nervous system, causes distinct neurological symptoms, and indirectly results in opportunistic infections, which include herpes virus simplex (HSV)-1, HSV-2, varicella zoster virus, and cytomegalovirus encephalitis caused by immunodeficiency. Early HIV-1 invasion of the central nervous system is also possible, and acute encephalopathy is a potentially lethal complication. We encountered a case of fulminant encephalopathy as a primary presentation of acute HIV-1 infection, in which highly active antiretroviral treatment resulted in a full clinical recovery...
