A survival case of visceral disseminated varicella zoster virus infection in a patient with systemic lupus erythematosus.

BACKGROUND: Visceral disseminated varicella zoster virus (VZV) infection is a rare but life-threatening complication in immunosuppressed patients. Herein, we report a survival case of visceral disseminated VZV infection in a patient with systemic lupus erythematosus (SLE). CASE PRESENTATION: A 37-year-old woman was diagnosed as SLE and initial induction therapy was started. Two months after starting the immunosuppressive therapy consisting of 40 mg of prednisolone (PSL) and 1500 mg of mycophenolate mofetil (MMF) daily, she suddenly developed strong abdominal pain, which was required opioid analgesics, followed by systemic skin blisters, which were diagnosed as varicella. Laboratory findings showed rapid exacerbation of severe liver failure, coagulation abnormalities and increased numbers of blood VZV deoxyribonucleic acid (DNA). Therefore, she was diagnosed as visceral disseminated VZV infection. Multidisciplinary treatment with acyclovir, immunoglobulin and antibiotics was started, the dose of PSL was reduced, and MMF was withdrawn. By their treatment, her symptoms were resolved and she finally discharged. CONCLUSIONS: Our case highlights the importance of a clinical suspicion of visceral disseminated VZV infections, and the necessity of immediate administration of acyclovir and reduced doses of immunosuppressant to save patients with SLE.

Disseminated varicella-zoster virus infection in an aplastic anemia- paroxysmal nocturnal hemoglobinuria syndrome patient: A case report.

Background: Varicella-zoster virus (VZV) is a common and widespread human-restricted pathogen. It is famous for its dermatological manifestations, such as varicella and herpes zoster. Patients with aplastic anemia-paroxysmal nocturnal hemoglobinuria (AA-PNH) syndrome complicated with fatal disseminated varicella zoster virus infection are very rare and in danger. Patient concerns: A 26-year-old man with a history of AA-PNH syndrome was receiving cyclosporine and corticosteroid treatment in the hematology department. During his hospitalization in our hospital, he developed fever, abdominal pain, and lower back pain, and his face, penis, trunk, and limbs developed itchy rash. Subsequently, the patient had to undergo cardiopulmonary resuscitation because of sudden cardiac arrest, and be transferred to ICU for treatment. It was presumed that the cause is unknown severe sepsis. The patient's condition quickly progressed to multiple organ failure, accompanied by liver, respiratory, and circulatory failure, and signs of disseminated intravascular coagulation. Unfortunately, the patient died after 8 h of active treatment. Finally, we collected all the evidence and concluded that the patient died of AA-PNH syndrome combined with poxzoster virus. Conclusion: AA-PNH syndrome patients treated with steroids and immunosuppressants are prone to various infections, considering that herpes virus infection with chickenpox and rash as the initial manifestations is characterized by rapid progress and often accompanied by serious complications. It is more difficult to distinguish it from AA-PNH syndrome with skin bleeding points. If it is not identified in time, it may delay the treatment opportunity, make the condition worse, and cause serious adverse prognosis. Therefore, clinicians need to pay attention to it.

Severe varicella-zoster virus meningoencephalomyelitis coexisting with visceral disseminated varicella-zoster virus infection in a patient with lupus nephritis: A case report.

RATIONALE: Meningoencephalomyelitis and visceral dissemination infection are rare but life-threatening complications of either the primary infection or reactivation of varicella-zoster virus (VZV) in immunocompromised patients. To date, few studies have reported the co-existence of VZV meningoencephalomyelitis and the visceral dissemination of VZV infection. PATIENT CONCERNS: A 23-year-old male was diagnosed with lupus nephritis class III and was being treated with oral prednisone and tacrolimus. The patient exhibited herpes zoster 21-day after the initiation of therapy and experienced unbearable abdominal pain and generalized seizures 11 days after the onset of a zoster rash. Magnetic resonance imaging showed progressive lesions in the cerebrum, brainstem, and cerebellum, as well as meningeal thickening and thoracic myelitis. Computed tomography showed pulmonary interstitial infiltration, partial intestinal dilatation, and effusion. Metagenomic next-generation sequencing revealed 198,269 and 152,222 VZV-specific reads in the cerebrospinal fluid and bronchoalveolar lavage fluid, respectively. DIAGNOSES: Based on the clinical and genetic findings, this patient was finally diagnosed with VZV meningoencephalomyelitis and visceral disseminated VZV infection. INTERVENTIONS: The patient received intravenous acyclovir (0.5 g every 8 hours) combined with plasma exchange and intravenous immunoglobulin. Treatment against secondary bacterial and fungal infections, organ support therapy and rehabilitation training were given simultaneously. OUTCOME: The patient's peripheral muscle strength did not improve and repeated metagenomic next-generation sequencing showed the persistence of VZV-specific reads in the cerebrospinal fluid. The patient finally abandoned therapy due to financial constraints at the 1-month follow-up. LESSONS: Patients with autoimmune diseases receiving immunosuppressive therapy should be warned about the possibility of developing serious neurological infections and visceral disseminated VZV infections as side effects. Early diagnosis and the early initiation of intravenous acyclovir therapy are important for such cases.

Zoster Sine Herpete: two unusual cases of varicella-zoster reactivation with atypical complaints of acute chest pain and severe headache.

In this case report, we describe two unusual presentations of varicella-zoster virus (VZV) reactivation without rash, a condition known as Zoster Sine Herpete (ZSH). In Case 1, a 58-year-old woman presented with severe right-sided chest pain under her breast that radiated to the ipsilateral back. After the initial workup ruled out cardiac and musculoskeletal etiologies, the characteristic dermatomal distribution of pain made us suspect VZV reactivation. A diagnosis of ZSH was made with positive VZV IgG and IgM serologies and symptomatic relief after famciclovir treatment. In Case 2, a 43-year-old woman presented with a severe headache and resolved sharp right flank pain. She was diagnosed with varicella meningitis after cerebrospinal fluid showed positive VZV DNA. Intravenous acyclovir treatment resulted in symptom resolution. The most common presentation of VZV reactivation is Herpes Zoster, or shingles, making ZSH a frequently missed diagnosis. High clinical suspicion is warranted to prevent life-threatening complications of ZSH.

[Varicella-zoster virus infection with concomitant lower cranial polyneuropathy in the absence of fever, headache and meningeal signs].

We present varicella-zoster virus (VZV) infection with concomitant lower cranial polyneuropathy in the absence of meningeal symptoms. Physical examination showed involvement of cranial nerves IX and X in Case 1 and of cranial nerves IX, X, and XI in Case 2. Cerebrospinal fluid (CSF) analysis revealed mild lymphocytic pleocytosis, normal protein levels, and absence of VZV-DNA based on polymerase chain reaction (PCR) analysis. Serum anti-VZV antibody testing showed positive results in both cases, which confirmed the diagnosis of VZV infection. VZV infection accompanied by lower cranial polyneuropathy is rare; therefore, it is important to consider VZV reactivation as an etiopathogenetic contributor to pharyngeal palsy and hoarseness. We emphasize the importance of serological analysis for precise diagnosis in VZV infection with multiple lower cranial nerve palsies because the VZV-DNA PCR test may show negative results in patients without meningitis symptoms or in those with normal CSF protein levels.

Herpes Simplex Virus and Varicella Zoster Virus Infections in Cancer Patients.

Herpes simplex virus (HSV) and varicella zoster virus (VZV) are alpha herpesviruses that establish life-long latent infection in neuronal ganglia after primary infection. Periodic reactivation of these viruses results in recurrent infections that can have significant impact on patients' quality of life. HSV commonly causes oral and genital mucocutaneous infections whereas VZV is responsible for varicella/chickenpox and herpes zoster/shingles, but cancer patients are at particularly higher risk of complications including disseminated and visceral infections due to impaired cell-mediated immunity. While diagnosis of more common HSV and/or VZV infections is frequently clinically based, immunocompromised hosts may have atypical skin presentation or visceral involvement. Thus, diagnostic confirmation using virus-specific tests such as polymerase chain reaction or immunohistochemical staining is crucial in some cases. Oral acyclovir, valacyclovir and famciclovir are usually used for mild to moderate infections and intravenous acyclovir is the drug of choice for severe or disseminated infections. Foscarnet can be used when acyclovir-resistance is confirmed or suspected. Pharmaceutical prophylaxis against HSV and/or VZV should be considered in high-risk cancers patients. Currently, there is no commercially available vaccine against HSV, but VZV vaccines are available to prevent varicella and zoster.

Visceral disseminated varicella zoster virus infection during non-intensive maintenance therapy in a patient with systemic lupus erythematosus.

Visceral disseminated varicella zoster virus infection (VD-VZV) is a rare complication in immunocompromised patients. Although systemic lupus erythematosus (SLE) patients have a higher risk of VZV infection, only a few reports describe VD-VZV in SLE. Here, we report a 48-year-old woman with SLE who had received maintenance therapy. She was transferred to the hospital because of severe epigastric pain. There were no significant abnormalities in abdominal computed tomography and upper gastrointestinal endoscopy. On hospital day 4, she developed vesicular eruption on her face and abdomen. VZV antigen was detected in specimens obtained from skin lesions, and treatment with acyclovir was started. VZV DNA in blood turned out to be positive, and the epigastric pain was thought to be caused by VD-VZV. There is a risk of VD-VZV in patients with SLE, even in those receiving non-intensive maintenance therapy.

Thrombotic Microangiopathy Secondary to Disseminated Varicella Zoster Virus Infection in an Adult Patient.

BACKGROUND Thrombotic microangiopathy (TMA) is a life-threatening condition caused by small-vessel platelet microthrombi. While various disease triggering factors, including infections, have been well described, there have been few reports of an association between TMA and varicella zoster virus (VZV) infection. VZV infection is rare among people age 20 and older, and infection-induced TMA is mostly reported in the pediatric age group. We report a case of TMA induced by a disseminated VZV infection in an adult. CASE REPORT A 43-year-old man presented with a 3-day duration of fever, headache, vomiting, and bloody diarrhea. He also reported body rash after a recent contact with a few roommates with chickenpox. On presentation, the patient developed convulsive seizures. His laboratory test results were significant for acute kidney injury (AKI) and thrombocytopenia. Atypical hemolytic uremic syndrome (aHUS) and thrombotic thrombocytopenic purpura (TTP) were suspected but further diagnostic testing was negative. The treatment plan included acyclovir, therapeutic plasma exchange, and high-dose oral prednisolone (1.5 mg/kg). The clinical and biochemical profile significantly improved, and the patient was discharged home. CONCLUSIONS TMA is a life-threatening hematological emergency with a high mortality rate. Compared to the pediatric population, VZV infection tends to be more severe in the adult age group. This case demonstrates that a high index of suspicion for TMA in adult patients with VZV who present with thrombocytopenia, even when there is no definitive diagnosis, can result in early management with favorable outcome.

Atypical anti-NMDA receptor encephalitis associated with varicella zoster virus infection.

The triggering effect of herpes simplex virus infection on the development of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is now well established. However, there are very few reports that has linked a varicella zoster virus (VZV) reactivation with anti-NMDAR encephalitis. In this report, we describe a case of a 57-year-old man presented with atypical clinical presentation of anti-NMDAR encephalitis with gait ataxia, complete ophtalmoplegia, and abolished reflexes followed by drowsiness and confusion. Initial diagnosis of Bickerstaff's brainstem encephalitis was suspected. Few days later, the patient developed herpes zoster in a localized right T1-T2 dermatome. Cerebrospinal fluid (CSF) polymerase chain reaction (PCR) for VZV was negative. CSF anti-NMDA antibodies were proved positive. A diagnosis of anti-NMDAR encephalitis with concomitant VZV skin reactivation was retained. Favorable outcome with combined antiviral treatment and immunomodulatory therapy was observed. Concomitant VZV reactivation with autoimmune encephalitis is possible. Prognosis and therapeutic options in this rare condition remain to be clarified.

[A 73-year-old man with polyradiculopathy and multiple cranial neuropathies emerging separate from the originating dermatome of a varicella zoster skin lesion].

A 73-year-old man developed delayed-onset multiple cranial neuropathies of cranial nerves V, VII and VIII, and segmental paresis in the ipsilateral upper extremity related to the C4 to Th1 segment, after all skin lesions with varicella zoster (VZV) on the left neck of the C3-4 dermatome had dried and crusted over. On admission, cerebrospinal fluid (CSF) revealed pleocytosis (all mononuclear cells, 12/µl). Treatment was started with intravenous acyclovir (10 mg/kg, every 8 h for 14 days) and methylprednisolone (1,000 mg/day for 3 days). Four days after starting treatment, left segmental paresis was improved, but the multiple cranial neuropathies persisted. Oral prednisolone (0.5 mg/kg/day) was administered for 5 days, then tapered off. All neurological symptoms had disappeared by hospital day 23. Of particular interest was the discrepancy between skin regions affected by VZV (C3-4) and the regions of cranial neuropathy (cranial nerves V, VII, and VIII) and muscle weakness innervated by C4-Th1. Although CSF was negative for VZV DNA according to PCR testing, the antibody index for VZV was elevated. This suggests intrathecal synthesis of VZV antibodies and supports the diagnosis of VZV meningitis. Also, all cranial nerves involved in this case were reported to have the cranial nerve ganglia where VZV could have established latency and been reactivated. This suggests concurrent reactivation on each cranial nerve ganglia without cutaneous lesions, as zoster sine herpete. In addition, anastomoses among the upper cervical nerves, which are found in some patients, may have contributed to this condition. These mechanisms underlie various neurological symptoms associated with VZV infection.

Visceral disseminated varicella zoster infection: a rare cause of acute abdomen in a patient with well-controlled diabetes mellitus-a case report.

BACKGROUND: Visceral disseminated varicella zoster virus (VZV) infections frequently affect immunocompromised patients. Diabetes mellitus has been associated with VZV infection, and most cases of disseminated infection involve patients with poorly controlled blood glucose levels. It initially presents as severe abdominal pain, which is evaluated as an acute abdomen, however, the cause is typically unidentified due to unremarkable computed tomography (CT) findings. We report a case of visceral disseminated VZV infection in a patient with well-controlled diabetes mellitus with fat stranding around the celiac and superior mesenteric artery on CT. CASE PRESENTATION: A 61-year-old Japanese woman with well-controlled diabetes mellitus presented to the emergency department with severe abdominal pain that gradually worsened. She had stable vital signs and skin rashes, suggestive of varicella. Abdominal CT showed fat stranding around the celiac and superior mesenteric arteries. The patient tested positive for the VZV antigen and was diagnosed with a visceral disseminated VZV infection. Acyclovir was administered, and the patient was discharged on the 14th day. CONCLUSIONS: Visceral disseminated VZV infection may affect patients with well-controlled diabetes mellitus and causes acute abdomen. Periarterial fat stranding on CT is associated with abdominal pain due to visceral disseminated VZV infection.

Visceral disseminated varicella-zoster virus infection in an immunocompetent host.

Varicella-zoster virus (VZV) can cause visceral disseminated VZV infection in immunocompromised patients. We experienced visceral disseminated VZV infection in an immunocompetent host. A 78-year-old woman visited our hospital complaining of abdominal pain that had persisted for 7 days. On day 3 after admission, a skin rash with blisters appeared mainly on her head and trunk that was diagnosed as generalized zoster via rapid skin VZV diagnostic kit. Esophagogastroduodenoscopy showed gastric erosions, and VZV was detected by real-time polymerase chain reaction testing of the gastric mucosal biopsy specimen. Computed tomography imaging also revealed pancreatitis and colitis, and she was diagnosed as having visceral disseminated VZV infection involving multiple organs. She was treated with acyclovir intravenously, after which her skin rash and abdominal pain disappeared. Because visceral disseminated VZV infection can occur in immunocompetent patients, this disease should be considered in patients with unexplained inflammatory lesions of the gastrointestinal tract or pancreas.

Varicella Zoster With Pemphigus-like Reaction.

ABSTRACT: We present a case of a 55-year-old man with a rash on his right foot that was biopsied and diagnosed as a Varicella Zoster virus infection with an accompanying positive immunohistochemical study with antiviral antibodies. He concomitantly suffered from a Varicella Zoster virus meningitis. The skin biopsies not only showed clear histologic signs of viral cytopathic effects but also showed intercellular IgG and C3 intraepidermal staining by direct immunofluorescence study, findings which are typically consistent with pemphigus vulgaris. However, the patient did not have any history of pemphigus; there was no mucosal involvement, and serum antibodies to desmoglein 1 and 3 were negative. After discharge, the patient continued to have right-sided foot pain, and he continued the acyclovir treatment.

An Autopsy Case of Disseminated Varicella Zoster Virus Infection during the Treatment of Nephrotic Syndrome.

A 68-year-old woman developed systemic blisters while receiving treatment for nephrotic syndrome. As she also developed marked liver dysfunction and disseminated intravascular coagulation, she was admitted to our hospital. She was diagnosed with varicella zoster virus (VZV) infection. Treatment was administered in the intensive-care unit, but the patient died on day 24 post-admission after severe VZV infection. A post-mortem examination showed micro-abscesses and necrosis caused by varicella zoster infection in multiple organs, including the liver, kidneys, and gastrointestinal tract. Because VZV infection can become severe in immunocompromised patients, careful consideration is needed for the prevention and treatment of the viral infection.

The Efficacy of Amenamevir for the Treatment of Disseminated Herpes Zoster Complicated with Probable Varicella-zoster Pneumonia in an Immunocompromised Patient.

We herein report the case of a 78-year-old woman who was diagnosed as having disseminated herpes zoster (DHZ) complicated with probable varicella-zoster pneumonia during maintenance therapy for microscopic polyangiitis. Because the patient had severe renal dysfunction, amenamevir administration was started to avoid any neurotoxicity of acyclovir, which is suggested to be optimal for treatment. It ameliorated her symptoms without any adverse events. This is the first report suggesting the efficacy of amenamevir in the treatment of severe herpes zoster infection with coexisting DHZ and probable varicella-zoster pneumonia. Amenamevir could thus be a treatment option for severe varicella zoster virus infections.
