[Recurrent herpetic erosion of the cornea: diagnosis, treatment and prevention of recurrences]. / gerpeticheskaya retsidiviruyushchaya eroziya rogovitsy: diagnostika, lechenie i preduprezhdenie retsidivov.

A group of patients was found to have a special form of recurrent corneal erosion caused by types I and II herpes virus. This form represents an independent form of ophthalmic herpes - herpetic recurrent erosion (HRE) of the cornea. The herpetic etiology of recurrent corneal erosion was confirmed by the immunofluorescence study of scraping from the conjunctiva, which revealed a high concentration of the herpes simplex virus antigen. Treatment of patients (171 patients, 182 eyes) with HRE included 2 consecutive stages: stage I - relief of acute symptoms of the disease with the help of conservative treatment (instillations of interferon inducers, autologous serum, corneal protectors, tear substitutes, use of therapeutic soft contact lenses); in some cases, phototherapeutic keratectomy was used in the absence of the effect of conservative therapy, as well as in the localization of the focus in the optical zone. Stage II involved anti-relapse therapy based on the use of a Russian-produced herpes vaccine in the intercurrent period. After vaccination, observation for 2 years or more showed that 81.3% of patients achieved clinical recovery (complete cessation of HRE recurrences), 15.8% had a decrease in the frequency and severity of relapses, while 2.9% of patients did not respond to the treatment.

Herpes Simplex Keratitis as a Complication of Pterygium Surgery.

BACKGROUND Infectious keratitis after pterygium surgery is a rare but potentially devastating complication. The present study presents 5 cases of herpes simplex keratitis (HSK) after pterygium surgery. CASE REPORT This study was conducted in our clinic in a 5-year period from February 2017 to September 2021. The 5 patients were men, aged between 42 and 73 years, with no prior history of herpes simplex virus (HSV) infections. Symptoms appeared near 1 month (median 30 days, range 10 to 70 days) after primary pterygium surgery. Diagnosis was based on clinical symptoms and laboratory test results, such as tear HSV-sIgA, corneal tissue polymerase chain reaction, and next-generation sequencing of metagenomics. The epithelial (1/5) and stromal (4/5) subtypes of HSK were identified. The patients received topical ganciclovir gel, immunosuppressive eyedrops, and oral acyclovir tablets, along with additional surgical interventions if necessary. Three were healed with conservative therapy, 1 eye required amniotic membrane transplantation due to corneal melt, and 1 was perforated and followed by corneal grafting. Finally, a literature review of previous publications on HSK after ocular surgeries was conducted. CONCLUSIONS HSK is a rare but serious complication that can arise after uneventful pterygium surgery. It is worthy of attention that both epithelial and stromal forms can occur. Timely diagnosis and treatment are crucial to prevent unfavorable outcomes. Consequently, routine corneal fluorescein staining, tear sIgA examination, and corneal scraping for polymerase chain reaction or next-generation sequencing of metagenomics should be performed in any suspected cases.

New-Onset of Herpes Simplex Keratitis After Blepharoplasty, Case Series and Review of the Literature.

PURPOSE: To report 3 cases of new-onset herpes simplex keratitis (HSK) after uncomplicated extraocular plastic surgery and discuss potential risk factors. METHODS: This case series includes 3 patients who underwent uncomplicated blepharoplastic surgery. Within 2 weeks postoperatively, all patients reported ocular discomfort, and their ophthalmic examinations revealed corneal lesions suspicious of HSK. One case was confirmed as an active herpes infection, and the other 2 cases were clinically diagnosed with HSK. The patients were treated with oral acyclovir and followed up for up to 6 weeks. RESULTS: All patients demonstrated improvement without sequelae at follow-up visits from 5 days to 4 weeks after initiating acyclovir treatment. CONCLUSIONS: Risk factors for new-onset HSK after uncomplicated extraocular surgeries may be related to an immunocompromised state, postoperative administration of topical or periocular corticosteroids, or environmental factors such as psychological stress. Ophthalmologists, particularly plastic surgeons, should be vigilant for ocular discomfort following eyelid surgeries and consider the possibility of herpes infection. This report highlights the importance of recognizing and managing HSK in the context of extraocular plastic surgery.

Herpetic Eye Disease Following the SARS-CoV-2 Vaccinations.

PURPOSE: To describe herpetic ocular infections following SARS-CoV-2 vaccinations. METHODS: A retrospective study of herpetic ocular infections after BNT162b2mRNA vaccination and a literature review. RESULTS: A cohort of five patients: three varicella zoster virus (VZV) and two herpes simplex virus (HSV) cases, as well as 19 literature cases: 9 cases of VZV and 10 cases of HSV post BNT162b2mRNA, AZD1222, mRNA-1273, and CoronaVac vaccinations. All cases presented within 28 days post vaccination. Most VZV and HSV cases (15/19) reported in the literature presented post first vaccine dose, while in our cohort 2 VZV cases presented post second dose and both HSV cases and one VZV case post third dose. The most common presentations were HZO with ocular involvement and HSV keratitis. All eyes had complete resolution; however, one had retinal detachment and three corneal scars. CONCLUSION: Herpetic ocular infections may develop shortly after SARS-CoV-2 vaccinations. Overall, the outcome is good.

Herpes simplex keratitis following Smart Pulse Technology assisted transepithelial photorefractive keratectomy: a case report.

BACKGROUND: Herpes simplex keratitis (HSK) is a rare and sight-threatening complication following refractive surgery. SmartSurfACE surgery is the result of combining transepithelial photorefractive keratectomy (trans-PRK) with Smart Pulse Technology (SPT) to diminish surface irregularities of the residual stromal bed after surgery with less pain, faster re-epithelialization, and better postoperative visual acuity. In this article, we report the first case of HSK following SmartSurf ACE without history of herpetic eye disease. CASE PRESENTATION: A 21-year-old woman underwent bilateral SmartSurfACE without history of clinical herpetic infection, active eye disease, or systemic disease. Mild superficial punctate keratitis occurred on the tenth postoperative day. The condition was not improved by ophthalmic drugs of anti-inflammation or epithelial healings. Dendritic corneal ulcer appeared within one month, which is the commonly recognized clinical manifestation of herpes simplex keratitis. The patient was managed with topical and systemic antiviral agents. After nine days of antiviral therapy, the lesion healed up, remaining mild stromal scarring in both eyes ultimately. CONCLUSION: Herpes simplex keratitis is a rare but sight-threatening complication following refractive surgery. For the ocular irritation symptoms of postoperative patients, we should consider the possibility of HSK and give timely treatment.

Reactivation of Herpes Simplex Keratitis on a Corneal Graft Following SARS-CoV-2 mRNA Vaccination.

Background: Ocular herpes simplex is usually caused by herpes simplex virus type 1 (HSV-1) and less commonly by the type 2 virus (HSV-2). Ocular manifestations of HSV include blepharitis, conjunctivitis, lacrimal system obstruction, corneal involvement, and uveitis. Corneal involvement is one of the causes of loss of vision and can be epithelial herpetic keratitis or stromal herpetic keratitis. Objective: A significant population has a colonization of herpes viruses. Under certain circumstances, these viruses can reactivate with a significant ocular morbidity. Globally, COVID-19 vaccines are recommended; however, the vaccine safety data are limited. Case report: Herein, we reported a case of herpetic keratitis reactivation that occurred 2 days after receiving SARS-CoV-2 mRNA vaccine. The patient is a 50-year-old man who underwent penetrating keratoplasty (PKP) in 2020 for corneal opacity caused by a previous herpes simplex keratitis in 2013. Herpetic keratitis was treated successfully with topical antiviral acyclovir along with topical moxifloxacin and artificial tears. After treatment, prophylactic oral acyclovir was started. Conclusion: Both ophthalmologist and patients should be aware of this phenomenon. Long-term prophylactic antiviral treatment may be recommended for those patients.

Stromal and endothelial herpes simplex virus keratitis reactivation in the convalescent period of COVID-19 - A case report.

A 73-year-old lady presented with a white spot and redness in the left eye for 1 month and had been treated elsewhere as a case of fungal keratitis. She had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral infection 2 months before. Her past ocular history and examination gave a probable diagnosis of herpetic stromal and endothelial keratitis. She responded to oral acyclovir and topical steroid, leading to resolution of stromal edema and inflammation. Anterior chamber fluid polymerase chain reaction (PCR) confirmed pathogen herpes simplex virus (HSV)-1. HSV ocular reactivation after coronavirus disease 2019 (COVID-19) has been reported currently. The present report will add knowledge about this potential opportunistic ophthalmic infection during the recovery phase of COVID-19 disease.

Herpes Simplex Virus Keratitis Reactivation after SARS-CoV-2 BNT162b2 mRNA Vaccination: A Report of Two Cases.

PURPOSE: To report two cases of herpes simplex virus keratitis reactivation following Pfizer-BioNTech COVID-19 (BNT162b2) mRNA vaccination. METHODS: Two patients (one male, age 42 years, and one female, age 29 years) who are known to have herpetic keratitis presented to our emergency room in a time frame between 4 days and 4 weeks of receiving the vaccine. One patient presented with necrotizing stromal keratitis; the other presented with endotheliitis and epithelial keratitis. PCR for herpes simplex virus (HSV) was obtained from the two patients, and all cases received systemic acyclovir. RESULTS: PCR for HSV came positive in both cases. Patients responded well to the provided treatment. CONCLUSION: Ocular herpetic infection may be activated by COVID-19 (BNT162b2) mRNA vaccine. Treating physician should be alert to such associations, and patients should be followed closely. No direct causality has been proven, but further reporting and investigating similar conditions is recommended.

Polluted Air Exposure Compromises Corneal Immunity and Exacerbates Inflammation in Acute Herpes Simplex Keratitis.

Air pollution is a serious environmental issue worldwide in developing countries' megacities, affecting the population's health, including the ocular surface, by predisposing or exacerbating other ocular diseases. Herpes simplex keratitis (HSK) is caused by the herpes simplex virus type 1 (HSV-1). The primary or recurring infection in the ocular site causes progressive corneal scarring that may result in visual impairment. The present study was designed to study the immunopathological changes of acute HSK under urban polluted air, using the acute HSK model combined with an experimental urban polluted air exposure from Buenos Aires City. We evaluated the corneal clinical outcomes, viral DNA and pro-inflammatory cytokines by RT-PCR and ELISA assays, respectively. Then, we determined the innate and adaptive immune responses in both cornea and local lymph nodes after HSV-1 corneal by immunofluorescence staining and flow cytometry. Our results showed that mice exposed to polluted air develop a severe form of HSK with increased corneal opacity, neovascularization, HSV-1 DNA and production of TNF-α, IL-1ß, IFN-γ, and CCL2. A high number of corneal resident immune cells, including activated dendritic cells, was observed in mice exposed to polluted air; with a further significant influx of bone marrow-derived cells including GR1+ cells (neutrophils and inflammatory monocytes), CD11c+ cells (dendritic cells), and CD3+ (T cells) during acute corneal HSK. Moreover, mice exposed to polluted air showed a predominant Th1 type T cell response over Tregs in local lymph nodes during acute HSK with decreased corneal Tregs. These findings provide strong evidence that urban polluted air might trigger a local imbalance of innate and adaptive immune responses that exacerbate HSK severity. Taking this study into account, urban air pollution should be considered a key factor in developing ocular inflammatory diseases.

Production of the Cytokine VEGF-A by CD4+ T and Myeloid Cells Disrupts the Corneal Nerve Landscape and Promotes Herpes Stromal Keratitis.

Herpes simplex virus type 1 (HSV-1)-infected corneas can develop a blinding immunoinflammatory condition called herpes stromal keratitis (HSK), which involves the loss of corneal sensitivity due to retraction of sensory nerves and subsequent hyperinnervation with sympathetic nerves. Increased concentrations of the cytokine VEGF-A in the cornea are associated with HSK severity. Here, we examined the impact of VEGF-A on neurologic changes that underly HSK using a mouse model of HSV-1 corneal infection. Both CD4+ T cells and myeloid cells produced pathogenic levels of VEGF-A within HSV-1-infected corneas, and CD4+ cell depletion promoted reinnervation of HSK corneas with sensory nerves. In vitro, VEGF-A from infected corneas repressed sensory nerve growth and promoted sympathetic nerve growth. Neutralizing VEGF-A in vivo using bevacizumab inhibited sympathetic innervation, promoted sensory nerve regeneration, and alleviated disease. Thus, VEGF-A can shape the sensory and sympathetic nerve landscape within the cornea, with implications for the treatment of blinding corneal disease.

Fetal and neonatal abnormalities due to congenital herpes simplex virus infection: a literature review.

OBJECTIVE: Herpes simplex virus (HSV) infection during pregnancy can cause severe neonatal infections. It is also a rare cause of congenital infections. We aimed to describe fetal and neonatal abnormalities of congenital HSV infection in order to define the features that are accessible to prenatal diagnosis during ultrasound screening and/or during a work-up for congenital malformations. METHODS: We analysed all cases of congenital HSV infection (CHI) described before and/or after birth and identified in Pubed and classified the findings as accessible or not to prenatal diagnosis. RESULTS: Thirty-six cases of congenital herpes infection were reported, of which 15 were described prenatally and 21 postnatally. The most frequently reported malformations accessible to prenatal diagnosis were cerebral anomalies. The most common abnormalities described after birth were skin lesions and keratitis, which are not considered amenable to prenatal ultrasound detection. CHI can due to either HSV1 or HSV2 infection, whether primary or non-primary infection, with or without the presence of maternal symptoms. CONCLUSION: Prenatal ultrasound abnormalities due to CHI are rare, varied and non-specific. There is no clear role for fetal ultrasound in the routine management of women with primary or non-primary HSV infection in pregnancy. However, in fetuses with ultrasound abnormalities suggestive of congenital infection, HSV should still be considered as a differential diagnosis after the more common in utero infections, such as cytomegalovirus, are excluded.

Epithelial keratitis mimicking herpes simplex keratitis in a patient after cataract surgery: A case report.

RATIONALE: Epithelial keratitis is a common complication after cataract surgery. Many factors have been attributed to this clinical phenomenon. PATIENT CONCERNS: An 82-year-old woman without previous herpes simplex keratitis (HSK) underwent an uncomplicated clear corneal phacoemulsification procedure in the right eye. In the late postoperative period, epithelial keratitis developed in this same eye. DIAGNOSIS: An initial diagnosis of HSK was made clinically. The lesion was refractory to antiviral treatment and had progressed. After topical acyclovir cessation and vigorous lubrication, a diagnosis of toxic keratitis was finally made. OUTCOMES: The corneal epithelial defect and dendritic lesion presented initially. Responding to antiviral treatment, this corneal lesion aggravated and revealed large epithelial erosion. After topical acyclovir cessation and initiation of vigorous lubrication, the toxic keratitis was completely resolved. LESSONS: Epithelial keratitis following cataract surgery is a common complication and can be misdiagnosed early in its disease course. Physicians should be alert to the possibility of HSK. Polymerase chain reaction detection is helpful in diagnosing this disease.

Bilateral herpes simplex keratitis reactivation after lacrimal gland botulinum toxin injection.

Botulinum toxin A (BTA) injections into lacrimal gland are being used for refractory epiphora due to intractable lacrimal disorders with success rates reported from 18% to 86%. Most common side effects are transient ptosis and diplopia. We report a case of a 59-year-old female injected with 2.5 units of BTA injection in each lacrimal gland for functional epiphora. The patient had a history of herpes simplex viral keratitis that was quiescent for more than 2 years. After 3 weeks, she developed reactivation of viral keratitis bilaterally, which was successfully managed with antivirals and topical steroids. Reactivation of quiescent herpes simplex keratitis is a possibility after lacrimal gland BTA and caution should be exercised in such cases.

[Uveitis treated with biotherapy and/or DMARD: Analysis from the French Pharmacovigilance Study Base]. / Uvéites sous biothérapies et/ou DMARDs en rhumatologie : analyse de la base de données déclarative de la pharmacovigilance nationale française.

PURPOSE: To report the characteristics of uveitis cases occurring while on biologic therapy or disease-modifying antirheumatic drugs (DMARDs) reported to the French national pharmacovigilance database. METHODS: All the uveitis cases occurring in patients with chronic rheumatologic diseases, chronic inflammatory intestinal diseases or connective tissue diseases, while treated with DMARDs and/or biologic therapies between 2000 and 2015 and reported to the French National Pharmacovigilance Database were collected. RESULTS: During the study period, 32 cases of uveitis were reported (15 men, 17 women). Two patients were treated with one DMARD alone, 24 with biologic therapy alone, and six with both treatments. Anterior uveitis was diagnosed in 19 patients (8 cases were bilateral); intermediate uveitis was found (unilaterally) in one patient; posterior and diffuse uveitis occurred in 5 and 2 cases respectively. Five cases were inconclusive with regard to the anatomical type of uveitis. The uveitis was of infectious origin in 5 cases: 2 toxoplasmosis, 2 herpes virus and 1 tuberculosis. In the 27 other cases, it was not possible to state whether the uveitis was associated with the underlying disease (uncontrolled) or a side effect of the biologic/DMARD treatments. The occurrence of the uveitis led to 9 switches in biologic therapy and 13 discontinuations of treatment (8 complete discontinuations, 5 discontinuations only until uveitis remission was obtained). In 4 cases, the treatments were not modified. The database does not specify the ultimate course or rheumatologic disease activity at the time of the uveitis. CONCLUSIONS: The presence of uveitis while on biologic therapy must not be taken to indicate a therapeutic failure, especially if the ocular manifestation is isolated. In the case of uveitis occurring in patients treated with biologic therapies and/or DMARDs, infectious complications should be ruled out.
