Clinical Manifestations of Monkeypox.

Monkeypox is a global health issue caused by the monkeypox virus. It can spread from person to person through respiratory secretions, direct exposure to dermatological lesions of infected patients, or exposure to contaminated objects. It is more common in homosexual men, and most patients are asymptomatic. The gold standard for diagnosis is a real-time polymerase chain reaction. In the absence of testing facilities, clinicians rely upon detailed history to exclude other causes of fever with rashes. Initially, there is a prodrome phase of a few days, which is followed by the appearance of rashes. The dermatological manifestations are in the form of an exanthematous rash, which transforms through a macular, papular, and vesicular phase and disappears after crusting in approximately 3 weeks. There can be associated lymphadenopathy in these patients. Respiratory manifestations include nasal congestion and shortness of breath that may result in secondary bacterial infections. Additionally, patients can have neurological involvement in the form of encephalitis. Furthermore, ocular involvement can occur in the form of conjunctivitis, keratitis, and corneal ulceration. Other symptoms can include diarrhea, vomiting, myalgia, and backache. Since most patients do not require hospitalization, the approach to treatment is mainly vigilant monitoring, antiviral therapy, and management of associated complications.

Does This Patient With Acute Infectious Conjunctivitis Have a Bacterial Infection?: The Rational Clinical Examination Systematic Review.

Importance: Acute infectious conjunctivitis is characterized by ocular redness and discharge, and is a common clinical entity. Evidence-based tools to aid the clinical diagnosis of viral vs bacterial conjunctivitis are lacking and may contribute to overprescribing of topical antibiotics. Objective: To determine the relative prevalence of viral vs bacterial conjunctivitis in adults and children, and to determine which symptoms or signs are suggestive of a viral vs bacterial etiology. Data Sources: A MEDLINE search (January 1946-March 2022) yielded 1891 articles. Included articles were rated using a quality score based on a modified Rational Clinical Examination grading system. Methodological quality levels 1 through 4 required a microbiological reference standard for diagnosis, whereas quality level 5 (the lowest quality) used a clinical reference standard for diagnosis. Study Selection: Consecutive series of patients presenting with acute infectious conjunctivitis and case series of viral or bacterial conjunctivitis alone. Thirty-two studies were included in a meta-analysis to determine prevalence and diagnostic accuracy measures; 27 used a microbiological reference standard for diagnosis and 5 used a clinical reference standard for diagnosis. Results: In studies involving children (5 studies; 881 patients; mean age, 4.7 years [age range, 1 month-18 years]), the prevalence of bacterial conjunctivitis was higher than viral conjunctivitis (71% vs 16%, respectively, P = .01). In the only study of adults (n = 207 patients; mean age, 25.7 years), the prevalence of viral conjunctivitis was higher than bacterial conjunctivitis (78% vs 16%, respectively, P < .001). For the primary analysis of level 1 (n = 6) and level 2 (n = 5) studies (1725 patients total), the clinical findings that best distinguished a viral etiology for conjunctivitis from a bacterial etiology included pharyngitis (sensitivity range, 0.55-0.58; specificity range, 0.89-0.94; positive likelihood ratio [LR] range, 5.4-9.9), preauricular lymphadenopathy (sensitivity range, 0.17-0.31; specificity range, 0.93-0.94; positive LR range, 2.5-5.6), and contact with another person with red eye (sensitivity, 0.18 [95% CI, 0.14-0.22]; specificity, 0.93 [95% CI, 0.90-0.95]; positive LR, 2.5 [95% CI, 1.6-3.7]). Mucopurulent ocular discharge (sensitivity, 0.76 [95% CI, 0.60-0.87); specificity, 0.66 [95% CI, 0.58-0.73]; positive LR, 2.1 [95% CI, 1.7-2.6]) and otitis media (sensitivity, 0.24 [95% CI, 0.20-0.29]; specificity, 0.91 [95% CI, 0.85-0.94]; positive LR, 2.5 [95% CI, 1.5-4.4]) were associated with the presence of bacterial conjunctivitis. Conclusions and Relevance: In this review, bacterial conjunctivitis was more common than viral conjunctivitis in children and viral conjunctivitis was more common than bacterial conjunctivitis in adults, although the prevalence estimates were based on limited evidence. Symptoms and signs associated with a higher likelihood of viral conjunctivitis in adults and children included concomitant pharyngitis, an enlarged preauricular node, and contact with another person with red eye, and signs associated with a higher likelihood of bacterial conjunctivitis included the presence of mucopurulent discharge and otitis media, but no single symptom or sign differentiated the 2 conditions with high certainty.

[Ophthalmological manifestations of post-COVID-19 syndrome]. / Oftal'mologicheskie proyavleniya postkovidnogo sindroma.

The review presents data on damage to the organ of vision in patients recovered from the new coronavirus infection reflecting on the results obtained by various researchers from examining patients with varying severity of the disease, both during the active stage and after recovery. Possible ways of transmission of the infectious agent into the organ of vision were analyzed. The most common ocular manifestation of COVID-19 is conjunctivitis, while lesions of the retina and optic nerve were noted less often. The article also outlines the strategy for treatment and describes infection prevention measures for doctors and patients.

An Eye on COVID-19: A Meta-analysis of Positive Conjunctival Reverse Transcriptase-Polymerase Chain Reaction and SARS-CoV-2 Conjunctivitis Prevalence.

SIGNIFICANCE: This analysis and review demonstrate that, although emerging data indicate that the prevalence of severe acute respiratory coronavirus 2 (SARS-CoV-2) on the ocular surface and coronavirus disease 2019 (COVID-19) conjunctivitis is rare, the ocular surface remains of interest as a potential inoculation and transmission site for SARS-CoV-2. Continued safety precautions should be taken as more data become available.COVID-19, caused by SARS-CoV-2, is a novel, global pandemic that has infected millions and, up to this point, caused more than two million fatalities worldwide. The ocular surface has become of interest as a possible vector for transmission by acting as a direct inoculation site, being a conduit for the virus into the respiratory system or as a method of transmission from potentially infected conjunctiva or tears. The components necessary for SARS-CoV-2 to theoretically infect ocular tissues are present: binding receptors (angiotensin-converting enzyme 2 and cluster of differentiation 147) and mechanisms for cell entry (transmembrane protease serine 2 and cathepsin L). This meta-analysis of COVID-19 prevalence data indicates that SARS-CoV-2 RNA has been infrequently found in conjunctival samples when tested with reverse transcriptase-polymerase chain reaction. This review estimates the prevalence of SARS-CoV-2 on the ocular surface and prevalence of conjunctivitis in patients with laboratory-confirmed COVID-19. There is much to be learned regarding ocular tropism of SARS-CoV-2.

Quantitative Investigation of Viral Load in Acute to Subacute Human Adenovirus Type 54 Conjunctivitis.

To understand the clinical course of human adenoviral (HAdV) conjunctivitis and establish a better treatment regimen, 38 eyes of 19 patients with HAdV-54 conjunctivitis for less than one week from onset were evaluated for clinical signs and symptoms and DNA copy numbers. A viral load of 104-105 is required to develop symptoms of HAdV conjunctivitis, as symptoms were present in eyes with viral loads of ≥104 at least once during the course. Next, it was observed that asymptomatic infections in the contralateral eyes are common, as the virus was detected in most eyes that did not develop conjunctivitis. Furthermore, there was no rapid decrease in the viral load in healed eyes; on the contrary, the viral load in the healed eyes on day 15 was significantly higher than that in the unhealed eyes. This was likely due to corticosteroid instillation, which rapidly alleviated symptoms but prolonged the duration of viral shedding. Recently, combination treatment with iodine and corticosteroids has been recommended for HAdV conjunctivitis. Assessing changes in the viral load and clinical symptoms would be helpful to better understand the clinical course of this disease.

SARS-CoV-2-associated inflammatory multisystem disease in a 15-year-old boy / SARS-CoV-2-fertozéshez társuló többszervi megbetegedés 15 éves fiúban.

Összefoglaló. Újabb megfigyelések szerint a SARS-CoV-2-fertozést követoen gyermekekben a paediatric inflammatory multisystem syndrome (PIMS) elnevezésu, sokkállapottal szövodött Kawasaki-megbetegedéshez hasonlító, többszervi elégtelenségnek megfelelo tünetegyüttes alakulhat ki. A gyermekek többségében ilyenkor a direkt víruskimutatás már sikertelen, azonban a SARS-CoV-2 ellen képzodött antitest igazolhatja a diagnózist. Dolgozatunk célja az egyik elso hazai eset ismertetése. Egy 15 éves fiú került gyermek intenzív osztályos felvételre több napon át észlelt magas láz, kesztyu-, zokniszeru exanthema, conjunctivitis, többszervi elégtelenség, szeptikus sokk tüneteivel, akut gyulladásra utaló laboratóriumi eltérésekkel és diffúz hasi panaszokkal. Felvételét megelozoen néhány héttel SARS-CoV-2-fertozésen esett át. Felvételekor a direkt víruskimutatás sikertelen volt, ám a SARS-CoV-2 elleni antitest vizsgálata pozitív lett. Komplex intenzív terápia mellett állapota stabilizálódott. Az irodalmi ajánlásoknak megfeleloen immunglobulin-, acetilszalicilsav- és szteroidkezelésben részesítettük, melynek hatására állapota maradványtünetek nélkül rendezodött. A növekvo esetszámú gyermekkori SARS-CoV-2-fertozés mellett egyre gyakrabban várható a SARS-CoV-2-fertozést követo, a Kawasaki-betegség tüneteire emlékezteto PIMS kialakulása. Gyermekekben súlyos szeptikus állapot és többszervi elégtelenség esetén gondolni kell a PIMS lehetoségére, mely esetenként intenzív osztályos ellátást és célzott terápiát igényel. Legjobb tudomásunk szerint a leírásra került beteg a Magyarországon diagnosztizált egyik legkorábbi eset. Orv Hetil. 2021; 162(16): 602-607. Summary. Recently following SARS-CoV-2 infection, a new, multisystem disease (paediatric inflammatory multisystem syndrome, PIMS) with fever was recognized in children with shock and multiorgan failure. On of the first Hungarian cases will be described. A 15-year-old boy was admitted to the Paediatric Intensive Care Unit with persistent high fever, diffuse abdominal pain, septic shock, multiple organ failure, gloves- and socks-shaped cutan exanthema, conjunctivitis and laboratory signs of inflammation. Some weeks preceding his admission, symptoms of mild SARS-CoV-2 infection were revealed. At admission, the SARS-CoV-2 PCR and antigen tests were negative, however, the presence of IgG antibody was shown. Following complex supportive intensive care along with internationally recommended immunoglobulin, aspirin and steroid treatment, the patient was completely cured without any sequalae. In children after SARS-CoV-2 infection, PIMS could occur mimicking Kawasaki syndrome. At this time, in children virus PCR or antigen tests are usually negative already, but the presence of SARS-CoV-2 antibody could prove the preceding disease. Due to the increasing number of SARS-CoV-2 infections, the occurrence of post-SARS-CoV-2 PIMS in childhood is expected to increase. For paediatric patients, in case of severe septic state and multiple organ failure, PIMS should be also considered, which may require intensive care and targeted therapy. As far as we know, the described case is one of the earliest cases of PIMS in Hungary. Orv Hetil. 2021; 162(16): 602-607.

An Update on COVID-19 Related Ophthalmic Manifestations.

Purpose: To summarize ophthalmic manifestations of coronavirus disease (COVID-19) reported in the literature thus far.Methods: The PubMed database was systematically searched through October 24, 2020, to identify relevant articles using the following search terms: ("COVID-19" OR "SARS-CoV-2") AND ("eye" OR "ophthalmology" OR "retina" OR "retinal findings" OR "cornea" OR "conjunctiva"). Only articles published in English were included in this review.Results: The reported prevalence of ophthalmic manifestations is generally low, but correlates positively with the severity of the disease. Most commonly reported ocular manifestations are conjunctivitis, conjunctival hyperemia and chemosis. Retinal findings include microhemorrhages and flame-shaped hemorrhages, cotton wool spots, dilated veins, and tortuous vessels.Conclusion: Considering the COVID-19 cases have reached pandemic dimensions and are surging, yet again, it is of utmost importance to determine its ophthalmic manifestations and prevent their vision threatening complications. Further studies are warranted to establish whether the retinal findings appear due to the COVID-19 or are an incidental finding in patients with a preexisting diabetic or hypertensive retinopathy.

Evaluation of Nasopharyngeal and Conjunctival Swab Samples of Hospitalised Patients with Confirmed COVID-19.

PURPOSE: To evaluate the results of conjunctival and nasopharyngeal swab tests in patients with confirmed COVID-19. METHODS: This prospective study included 45 patients who were hospitalized for confirmed COVID-19. Nasopharyngeal swab samples were obtained from the patients before hospitalization. Only one eye of each patient was randomly selected for-conjunctival sampling. All participants underwent a complete slit-lamp examination. Conjunctival and nasopharyngeal swab samples were analyzed by reversetranscriptase-polymerase-chain reaction (RT-PCR). RESULTS: Twenty seven (60%) of the patients were male and 18 (40%) were female. Conjunctival swab was positive in only one (2.22%) patient. None of the COVID-19 patients showed ocular changes and symptoms. There were no abnormalities of the ocular surface, anterior chamber or posterior segment at slit-lamp examination. CONCLUSIONS: The RT-PCR was not high positive in the conjunctiva as in nasopharyngeal swabs. Ocular changes were not common in COVID-19 patients.

Herpes Simplex Virus-Related Conjunctivitis Resistant to Aciclovir: A Case Report and Review of the Literature.

PURPOSE: To report a rare case of herpes virus type 2-related conjunctivitis, resistant to aciclovir (ACV). METHODS: Case report and review of literature. RESULTS: A 28-year-old human immunodeficiency virus-positive man presented with chronic, recurrent follicular conjunctivitis. Multiplex reverse transcription polymerase chain reaction assay testing was positive for herpes simplex virus (HSV); subsequent typing with HSV assay revealed the presence of HSV type 2. Oral ACV failed to control the disease, and the patient continued to worsen clinically until resistance testing was performed. This revealed an M183stop within thymidine kinase, thus confirming the suspected resistance. The patient improved after 14 days of high-dose continuous intravenous infusion of ACV. CONCLUSIONS: This is a rare case of isolated conjunctivitis due to herpes virus type 2, in an human immunodeficiency virus-positive patient, which was found to be resistant to ACV. Drug-resistant HSV is likely to emerge as an important clinical entity in the future, increasing the need for new drugs with novel mechanisms of action.

Conjunctivitis Related to not Severe COVID-19: A Case Report.

PURPOSE: The purpose of this article is to report a bilateral conjunctivitis case in a patient with confirmed 2019 novel coronavirus disease (COVID-19). CASE REPORT/OBSERVATIONS: A 24-year-old healthy man developed severe conjunctivitis in his right eye, followed by his left eye 4 days after fever and myalgia. He reported yellowish conjunctival discharge, foreign body sensation, redness, and tearing, and those symptoms were resolved in 10 days. Analyses of nasopharyngeal secretions identified SARS-CoV-2 by polymerase chain reaction (PCR). CONCLUSION: Mild COVID-19 can cause severe bilateral conjunctivitis. The ophthalmologist may be aware of conjunctival secretions, a possible path of infection, during eye checkup.

Outcomes of the Ophthalmic Examinations in Patients Infected by SARS-CoV-2.

Purpose: To evaluate ophthalmic examination results which were performed with slit-lamp biomicroscope, in patients with laboratory-confirmed SARS-CoV-2 infection.Methods: In the present study, 50 patients with laboratory-confirmed SARS-CoV-2 infection, were enrolled. Ophthalmic examination with slit-lamp biomicroscopy was performed and the results were evaluated.Results: The mean age of 50 patients (24 females, 26 males) included in this study, was 58,26 ± 18,91 years. In nine patients, bilateral acute follicular conjunctivitis was present. In two patients, acute anterior uveitis was seen. Optic disc and macula were normal in all patients. Preauricular lymphadenopathy (LAP) was found in 6 (12%) patients. Of these six patients, five had follicular conjunctivitis, and one had anterior uveitis.Conclusion: Acute follicular conjunctivitis with preauricular LAP and anterior uveitis were detected and no fundus pathologies were found in detailed ophthalmic examination in patients with laboratory-confirmed SARS-CoV-2 virus infection.

The efficacy and safety of Yuxingcao eye drops in the treatment of COVID-19 conjunctivitis: A protocol for a systematic review.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a global pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). There is no specific cure for this disease, and the clinical management mainly depends on supportive treatment. This disease may affect SARS-CoV-2 conjunctivitis. Yuxingcao eye drops is used in treating COVID-19 conjunctivitis in China. METHODS: A comprehensive literature search will be conducted. Two methodological trained researchers will read the title, abstract, and full texts and independently select the qualified literature according to inclusion and exclusion criteria. After assessment of the risk of bias and data extraction, we will conduct meta-analyses for outcomes related to COVID-19 conjunctivitis. The heterogeneity of data will be investigated by Cochrane X and I tests. Then publication bias assessment will be conducted by funnel plot analysis and Egger test. RESULTS: The results of our research will be published in a peer-reviewed journal. CONCLUSION: Our study aims to systematically present the clinical evidence of Yuxingcao eye drops in treating COVID-19 conjunctivitis, which will be of significant meaning for further research and clinical practice.

Ocular surface manifestations of coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis.

PURPOSE: This study was performed to determine the occurrence of ocular surface manifestations in patients diagnosed with coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: A systematic search of electronic databases i.e. PubMed, Web of Science, CINAHL, OVID and Google scholar was performed using a comprehensive search strategy. The searches were current through 31st May 2020. Pooled data from cross-sectional studies was used for meta-analysis and a narrative synthesis was conducted for studies where a meta-analysis was not feasible. RESULTS: A total of 16 studies reporting 2347 confirmed COVID-19 cases were included. Pooled data showed that 11.64% of COVID-19 patients had ocular surface manifestations. Ocular pain (31.2%), discharge (19.2%), redness (10.8%), and follicular conjunctivitis (7.7%) were the main features. 6.9% patients with ocular manifestations had severe pneumonia. Viral RNA was detected from the ocular specimens in 3.5% patients. CONCLUSION: The most common reported ocular presentations of COVID-19 included ocular pain, redness, discharge, and follicular conjunctivitis. A small proportion of patients had viral RNA in their conjunctival/tear samples. The available studies show significant publication bias and heterogeneity. Prospective studies with methodical collection and data reporting are needed for evaluation of ocular involvement in COVID-19.

Management of conjunctivitis and other causes of red eye during the COVID-19 pandemic.

BACKGROUND: Patients with red eyes frequently present to general practitioners (GPs). Although infrequent, some patients with COVID-19 may present with features typical of viral conjunctivitis. SARS-CoV-2 is expressed at a low rate in tears, which may be a source of infection to GPs caring for patients at high risk of COVID­19. OBJECTIVE: The aims of this article are to outline: 1) ophthalmic complications of SARS-CoV-2 infection, 2) triage and management of patients with potential COVID-19 conjunctivitis, and 3) triage and management of patients with red eyes during the current COVID-19 pandemic. DISCUSSION: It is important that GPs: 1) have a high index of suspicion that patients with apparently typical viral conjunctivitis may have an uncommon presentation of COVID-19 illness, 2) develop appropriate telephone triage systems to reduce patient consultations, and 3) foster relationships with their ophthalmologist and optometrist colleagues who can provide phone advice, guidance on treatment initiation and definitive care when necessary.

Retinal involvement and ocular findings in COVID-19 pneumonia patients.

Changes in immune and coagulation systems and possible viral spread through the blood-brain barrier have been described in SARS-CoV-2 infection. In this study, we evaluated the possible retinal involvement and ocular findings in severe COVID-19 pneumonia patients. A cross-sectional study was conducted on 46 patients affected by severe COVID-19 who were hospitalized in one intensive care unit (ICU) and in two infectious disease wards, including bedside eye screening, corneal sensitivity assessment and retinography. A total of 43 SARS-CoV-2-positive pneumonia patients affected with COVID-19 pneumonia were included, including 25 males and 18 females, with a median age of 70 years [IQR 59-78]. Except for one patient with unilateral posterior chorioretinitis of opportunistic origin, of whom aqueous tap was negative for SARS-CoV-2, no further retinal manifestation related to COVID-19 infection was found in our cohort. We found 3 patients (7%) with bilateral conjunctivitis in whom PCR analysis on conjunctival swabs provided negative results for SARS-CoV-2. No alterations in corneal sensitivity were found. We demonstrated the absence of retinal involvement in SARS-CoV-2 pneumonia patients. Ophthalmologic evaluation in COVID-19, particularly in patients hospitalized in an ICU setting, may be useful to reveal systemic co-infections by opportunistic pathogens.
