SGK1 mediates herpes simplex keratitis via the PI3K/SGK1/ Wnt signaling pathways.

Herpes simplex virus type 1 (HSV-1) is a common virus infecting the ocular tissue. It infects eye tissues, such as the eyelid, cornea, and conjunctiva. Corneal HSV-1 infection causes herpes simplex keratitis (HSK), which can induce vision loss. Current treatments for eye infections targeting HSV-1 can led to various sequelae. Antiviral drugs only work during active viral replication, and viral resistance has been recorded in numerous cases. Therefore, it is necessary to determine the molecular mechanisms underlying HSV-1 infection and identify new antiviral drugs. There are no reports on wheth…

KEY CLINICAL MESSAGE: Oral Erythema Multiforme (EM) is considered rare and less described variant in the world of EM. Examination of oral ca … rious etiological factors including infections, medications, autoimmune diseases, and malignancies; herpes simplex being the most common infection accounting for almost 90 percent of the overall cases. Here, we report a case of EM in an 8-year-old female child. The patient presented with an acute onset of crusting ulcers in the lips and oral cavity along with sp …

[Herpes simplex encephalitis complicated with cerebral salt wasting syndrome: a case study].

A 78-year-old man was admitted to the hospital with a 4-day history of fever and confusion. Physical examination revealed oral dryness and decreased skin turgor. Blood tests showed hyponatremia (121.5 ‍mEq/l), and cerebrospinal fluid examination revealed positivity for herpes simplex virus 1 (HSV-1) via polymerase chain reaction. He was diagnosed with herpes simplex encephalitis and initiated acyclovir treatment. The hyponatremia was diagnosed as cerebral salt wasting syndrome (CSWS) and treated with hypertonic saline infusion and fludrocortisone. The cerebrospinal fluid HSV-1 DNA became negat…

Herpes simplex virus dissemination with necrotizing hepatitis following Descemet membrane endothelial keratoplasty.

BACKGROUND: Corneal transplants are the most common type of transplant and increasing in frequency. Donor cornea tissues are a rare source of herpes simplex virus (HSV) transmission and not routinely tested for presence of HSV. Donor graft-to-recipient transmission typically causes graft failure and anterior uveitis, and extra-ocular HSV disease has not been previously reported. We present a case of HSV transmission from donor cornea tissue that nearly cost the corneal transplant recipient his life. CASE REPORT: An elderly immunocompetent man developed an acute illness 10 days after having do…

"Knife-cut" intertriginous ulcers related to herpes simplex virus in three patients.

Linear intertriginous erosions and ulcerations related to herpes simplex virus (HSV) infection have been reported in patients with underlying immunosuppression. This rare presentation of HSV seems to occur predominantly in patients undergoing treatment of hematologic malignancies and rheumatologic conditions. Herein, we report three cases of linear "knife-cut" ulcerations in patients who were not undergoing active pharmacologic immunosuppressive therapy and lacked coexisting malignancy or autoimmune disease. Close examination of the skin folds for HSV infection is warranted to rule out dissemi…

Histone deacetylase inhibitors enhance oncolytic herpes simplex virus therapy for malignant meningioma.

Approximately 20% of meningiomas are not benign (higher grade) and tend to relapse after surgery and radiation therapy. Malignant (anaplastic) meningioma (MM) is a minor subset of high-grade meningioma that is lethal with no effective treatment options currently. Oncolytic herpes simplex virus (oHSV) is a powerful anti-cancer modality that induces both direct cell death and anti-tumor immunity, and has shown activity in preclinical models of MM. However, clinically meaningful efficacy will likely entail rational mechanistic combination approaches. We here show that epigenome modulator histone …

BACKGROUND: Herpes simplex virus (HSV) is a rare cause of acute viral hepatitis but has high mortality rates and primarily affects immunocompromised hosts. We report a case of HSV hepatitis in a 20-year-old female kidney transplant recipient who had 1000-fold elevations in transaminases on post-transplant day 14, and the strategies employed for diagnoses and…

Herpes Simplex Virus-2 Encephalitis Complicated with Multiple Cranial Neuritis and Dysautonomia.

INTRODUCTION: Herpes simplex encephalitis (HSE) is mainly caused by herpes simplex virus-1 infection (HSV-1). Herpes simplex virus-2 (HSV-2) infection is rare except in neonates or the immune-compromised. Cranial neuritis is rarely reported in association with HSE. This case study in an eleven-month-old followed by a literature review on cranial neuritis in HSE in children is presented due to the rarity of both situations. CASE REPORT: An eleven-month old otherwise healthy infant presented with encephalitis due to HSV-2 infection which was complicated with dysautonomia manifesting as blood pr…

[Herpes Simplex Virus Infection in Two Premature Infants - Diagnostic and Therapeutic Management].

Herpes simplex virus type 1 or 2 (HSV 1/2)-related infections in neonates are rare but associated with high morbidity and mortality, especially if specific treatment is delayed. Due to immaturity of the immunological system, premature infants are particularly at risk. In addition, symptoms of neonatal HSV infections may imitate prematurity-related problems, such as sepsis. So, a thorough patient's history and appropriate diagnostic measures are important to confirm the diagnosis. We present 2 premature infants with systemic HSV infections and discuss diagnostic and therapeutic management. Both…

Use of pritelivir in refractory aciclovir-resistant herpes simplex virus type 2.

Recurrence of mucocutaneous herpes simplex virus (HSV) infections is common in immunosuppressed patients. Thymidine kinase mutations conferring resistance to the antiviral agent aciclovir have been observed in such patients. Recommended second-line therapeutic agents against HSV are associated with significant side effects contributing to disease burden. We present a case of aciclovir-resistant herpes simplex virus 2 (HSV-2) in an immunosuppressed (HIV negative) allogenic peripheral blood stem cell transplant (SCT) recipient which was refractory to second-line therapy. Compassionate acquisitio…

Herpes simplex encephalitis in patients receiving chemotherapy and whole-brain radiation therapy.

Herpes simplex encephalitis (HSE) is a very severe infection of the central nervous system (CNS) caused mainly by herpes simplex virus type 1 (HSV-1) and occasionally by herpes simplex virus type 2 (HSV-2). After relapse or drug-resistant to chemotherapy, whole-brain radiation therapy (WBRT) is a mainstay of treatment in patients with both identifiable brain metastases and CNS lymphoma. Although HSV-1 encephalitis predominantly affects immunocompetent host, HSV encephalitis may be more common in immune-suppressed patients than is currently recognized. Disease presentation may be atypical inclu…

Thrombocytopenia Secondary to Herpes Simplex Virus-2 Infection Successfully Treated by Acyclovir.

Thrombocytopenia is a common clinical condition associated with a wide variety of clinical conditions including infections, malignancy, medications, liver disorder, and autoimmune conditions, etc. The association between thrombocytopenia and herpes simplex virus (HSV) is reported only once in a case report dating back to 1978. We report a case of a 66-year-old female with generalized weakness, mechanical fall, genital ulcerations, and breast fold and genital area skin redness, warmth, and mild tenderness. Initial labs showed mild leukocytosis, normal platelet count, mild lactic acidosis, and u…

The controversial natural history of oral herpes simplex virus type 1 infection.

The natural history of oral herpes simplex virus type 1 (HSV-1) infection in the immunocompetent host is complex and rich in controversial phenomena, namely the role of unapparent transmission in primary infection acquisition, the high frequency of asymptomatic primary and recurrent infections, the lack of immunogenicity of HSV-1 internalized in the soma (cell body) of the sensory neurons of the trigeminal ganglion, the lytic activity of HSV-1 in the soma of neurons that is inhibited in the sensory neurons of the trigeminal ganglion and often uncontrolled in the other neurons, the role of kera…

Successful Therapy of Severe Oro-Labial Herpes Simplex With Muco-Adhesive Acyclovir.

Although muco-adhesive acyclovir 50mg tablets are only approved for the management of recurrent oro-labial HSV-1 infections, their ability to achieve extremely high concentrations in saliva and oral tissues suggests the potential for other uses. In this case, the agent was successfully utilized as a single tablet monotherapy leading to rapid clinical resolution of severe post-operative oro-labial infection. <p><em>J Drugs Dermatol. 2018;17(4):479-480.</em></p>.
