Sexually transmitted infections and HIV in ophthalmology.

The ocular and periocular manifestations of sexually transmitted infections are heterogeneous in etiology, manifestations, and complications. Etiologic agents include bacteria, viruses, parasites, and protozoa, which are most frequently transmitted via direct ocular contact with an active lesion or infected bodily fluid, autoinoculation, or dissemination from a distant site. Vertical transmission most commonly occurs perinatally during vaginal delivery. The complications of ophthalmia neonatorum can be severe, with the potential for permanent blindness or life-threatening systemic involvement if untreated. Clinical features, diagnostic modalities, and therapeutic regimens vary based on etiology and are summarized in this review. Prompt diagnosis is imperative, given the severe sequelae that may result from ocular involvement in these infections, including permanent vision loss. A multidisciplinary approach, involving both ophthalmology and dermatology, to diagnosis and management is essential to mitigate the risk of morbidity associated with sexually transmitted infections resulting in eye disease.

Is Ophthalmia Neonatorum Associated With Invasive Bacterial Infection? A Single-Center Retrospective Study.

OBJECTIVE: Ophthalmia neonatorum (ON) is a conjunctivitis occurring in neonates and can be caused by multiple bacterial pathogens. The risk of invasive bacterial infection (IBI) in neonates with ON is poorly known. Our objectives were to document the association of ON with IBI in term neonates and to investigate practice variation. METHODS: This was a retrospective observational study of all neonates who presented to a single emergency department (ED) between January 2018 and December 2019. Participants were all children with a final diagnosis of ON according to the treating physician as registered in the ED computerized database. Newborns with craniofacial malformations and premature infants were excluded. The primary outcome was IBI as defined by growth of any bacterial pathogen in the blood or cerebrospinal fluid. Perinatal risk factors, ED visit details (symptoms on presentation, management, and treatment plan) as well as complications (ocular morbidity, death, and unscheduled return visits) were collected. Data were analyzed using descriptive statistics. RESULTS: Fifty-two term neonates were included. There were no cases of IBI associated with ON (0%; 95% confidence interval [CI], 0%-6.9%). Six ocular bacterial infections were identified, one of which was Chlamydia trachomatis . Although there were no IBIs, ocular complications, deaths, or unscheduled return visits to the ED, there was a wide variation in physician's management of ON. Physicians ordered investigations in 49% (95% CI, 34%-62%) of neonates, prescribed antibiotics to 87% (95% CI, 74%-94%), and involved specialists in 39% (95% CI, 27%-52%) of cases. CONCLUSIONS: Emergency department presentations of term neonates with ON are associated with a low risk of IBI. A better understanding of the current practice variation is needed to inform clinical guidelines for the management of neonates with ON presenting to the ED.

Antibiotic prophylaxis for ophthalmia neonatorum in Italy: results from a national survey and the Italian intersociety new position statements.

BACKGROUND: Ophthalmia neonatorum is an acute conjunctivitis that occurs in newborns within the first month of life. The most serious infections are due to Chlamydia trachomatis and Neisseria gonorrhoeae, that may cause permanent damages. The use of ophthalmic prophylaxis varies widely around the world, according to the different health and socio-economic contexts. To date in Italy there is no a clear legislation regarding ophthalmia neonatorum prophylaxis at birth. METHODS: We invited all birth centers in Italy to carry out a retrospective survey relating the last three years. We collected data regarding demographics of neonates, drugs used for ophthalmic prophylaxis and results of the screening of pregnant women for Chlamydia trachomatis and Neisseria gonorrhoeae vaginal infections. RESULTS: Among 419 birth centers, 302 (72,1%) responded to the survey. Overall 1041384 neonates, 82,3% of those born in the three years considered, received ophthalmic prophylaxis. Only 4,585 (0,4%) of them received one of the drugs recommended by the WHO. The Centers that participated to the survey reported 12 episodes of Chlamydial conjunctivitis and no Gonococcal infection in the three years. Only 38% of the Centers performed vaginal swabs to pregnant women: 2,6% screened only for Neisseria, 9,6% only for Chlamydia and 25,8% for both germs. CONCLUSIONS: The data obtained from the survey showed a low incidence of neonatal conjunctivitis due to either Neisseria gonorrhoeae or Chlamydia trachomatis in Italy. Due to the lack of legislation regulating the prophylaxis of ophthalmia neonatorum in newborns, the Italian Society of Neonatology, the Italian Society of Obstetrics and Gynecology and the Italian Society of Perinatal Medicine have recently issued new recommendations on this topic.

Ophthalmia Neonatorum, Helen Keller, and the Social Dimensions of Eye Disease.

PURPOSE: The aim of this study was to describe how an early 20th-century American celebrity attempted to influence public perception of ophthalmic neonatorum. METHODS: This study reviews the editorial written by Helen Keller in the 1909 Ladies' Home Journal and related historical documents about the prevention of blindness from neonatal conjunctivitis. RESULTS: Although blind, deaf, and nulliparous, Helen Keller at the age of 29 sensed that the newborn children of many American women were being denied preventative treatment for ophthalmia neonatorum. In her editorial in the Ladies' Home Journal discussing the complications of venereal disease she urged women to become proactive in matters of personal and family health care. CONCLUSIONS: Helen Keller viewed blindness from ophthalmia neonatorum as a failure of the American health care system. Her solution was to impart women with enough knowledge to seek care from educated medical professionals. The observation that many women and their children were receiving substandard care reflected a fundamental problem with disparities in the delivery of perinatal health care. Her insights are as relevant today as they were in 1909.

Case series and literature review of chlamydial ophthalmia neonatorum in Botswana.

BACKGROUND: We describe 12 cases of chlamydial ophthalmia neonatorum and the current scientific evidence on its prevention and treatment. The data presented were obtained from the "Maduo" study, a prospective observational study of the relationship between curable sexually transmitted infections and adverse neonatal outcomes at four antenatal clinics in Gaborone, Botswana. METHODS: Infants of mothers with perinatal chlamydia infection were evaluated for chlamydial ophthalmia neonatorum based on clinical presentation of conjunctivitis or positive test via GeneXpert CT/NG assay. Data on 29 infants born to mothers with postnatal C. trachomatis infection were analysed. RESULTS: 12 infants were diagnosed with chlamydial ophthalmia neonatorum. Eight of those cases were confirmed with the GeneXpert CT/NG assay while four were identified as probable cases based on clinical history and presentation. Overall, nine infants presented with signs of conjunctivitis, while three who had a positive diagnostic test result had asymptomatic infection. All but one infant had received ocular 1% tetracycline prophylaxis at birth, and four infants had signs suggestive of chlamydial pneumonia at presentation. Two out of five symptomatic cases whose mothers reported completion of their treatment course with erythromycin had lingering symptoms. CONCLUSIONS: Our findings affirm that the current prophylaxis and treatment modalities for chlamydial ophthalmia neonatorum are inadequate. To the extent feasible in low- and middle-income countries, we recommend implementation of routine C. trachomatis screening and treatment in pregnant women.

Neonatal ocular prophylaxis in the United States: is it still necessary?

INTRODUCTION: Much has changed since Credé reported that silver nitrate decreases the incidence of ophthalmia neonatorum. Prenatal screening and treatment of pregnant women for Neisseria gonorrhoeae became standard in the 1950s and for Chlamydia trachomatis in 1993. Neonatal gonococcal and chlamydial conjunctivitis are consequently uncommon today. Currently, only 0.5% erythromycin ophthalmic ointment is available in the United States (U.S.) for neonatal ocular prophylaxis, which is ineffective against C. trachomatis. AREAS COVERED: This article addresses the altered epidemiology of ophthalmia neonatorum in the U.S. since prophylactic practices began, the lack of data supporting ophthalmic erythromycin for prevention of neonatal gonococcal and chlamydial conjunctivitis, and the impact of prenatal screening and treatment of pregnant women for N. gonorrhoeae and C. trachomatis on conjunctivitis incidence. The authors discuss why erythromycin ophthalmic ointment is likely ineffective against gonococcal ophthalmia, including the development of macrolide resistance. Physiologic limitations and pharmacokinetic properties are considered with respect to ophthalmic erythromycin for the prevention of gonococcal and chlamydial conjunctivitis. EXPERT OPINION: Administration of erythromycin ophthalmic ointment for the prevention of neonatal conjunctivitis is not literature-supported. Prenatal screening and treatment of pregnant women is the most effective way to prevent ophthalmia neonatorum. National mandates for prophylaxis should be withdrawn.

Universal ophthalmia neonatorum prophylaxis in Ontario: a cost-effectiveness analysis.

BACKGROUND: Although prophylaxis for ophthalmia neonatorum at birth is required by law in Ontario, declining prevalence of disease and efficacy of prophylaxis have called this practice into question. The objective of this modelling study was to assess the cost-effectiveness of universal prophylaxis for ophthalmia neonatorum to inform decision-makers on the potential impact of a change in this policy. METHODS: We compared the cost-effectiveness of prophylaxis for ophthalmia neonatorum with no prophylaxis through cost-utility analysis with a lifetime time horizon, considering a provincial government payer, for a hypothetical population of newborns in Ontario. We assessed both the mean incremental costs of prophylaxis and its mean incremental effectiveness using a hybrid (part decision tree, part Markov) model. We used a scenario analysis to evaluate alternative time horizons and discount rates. We conducted a threshold analysis to evaluate the impact of variations in the cost of prophylaxis and in the prevalence of sexually transmitted infections (gonorrhea and chlamydia). RESULTS: In our model, prophylaxis for ophthalmia neonatorum did not meet a willingness-to-pay threshold of Can$50 000 per quality-adjusted life-year (QALY). Although prophylaxis was effective in reducing morbidity associated with ophthalmia neonatorum, the number needed to treat to prevent 1 case of ophthalmia neonatorum blindness was 500 000, with an associated cost of more than Can$4 000 000. When compared with no prophylaxis, prophylaxis had an incremental cost of Can$355 798 per long-term QALY gained (incremental cost-effectiveness ratio). INTERPRETATION: We found that prophylaxis for ophthalmia neonatorum, although individually inexpensive, leads to very high costs on a population level. These findings contribute to the discussion on mandatory prophylaxis currently underway in several jurisdictions.

A Newborn with a Purulent Ocular Discharge.

An 11-day-old girl, who was diagnosed with Neisseria gonorrhoeae ophthalmia neonatorum, presents with a purulent ocular discharge. Although rare in regions with high implementation rates of ocular prophylaxis, ophthalmia neonatorum remains an important diagnostic consideration, especially in developing countries and areas of low socioeconomic status. In this article, we review the evolving epidemiology, diagnostic considerations, prevention, and treatment of ophthalmia neonatorum. [Pediatr Ann. 2022;51(5):e206-e208.].

Severe ophthalmia neonatorum in Southwest China: a 5-year review of demographics, microbiological results, and risk factors.

PURPOSE: To evaluate the microbiological characteristics and risk factors of severe ophthalmia neonatorum (ON) in Southwest China. METHODS: In this retrospective review, data on demography, microbiological results, and risk factors were analyzed. Data were obtained from medical records of patients with severe ON treated at Children's Hospital of Chongqing Medical University from January 2015 to December 2019. To understand the risk factors for severe ON, maternal and neonatal factors were compared between the severe and non-severe ON groups. RESULTS: A total of 1397 neonates with ON were included, of whom 12% (n = 172) had severe ON, and 88% (n = 1225) had non-severe ON. Microbial detection and drug susceptibility tests were performed on 169 patients with severe ON. Culture results were positive for 76 patients, with gram-positive bacteria in 71.1% (n = 54), gram-negative bacteria in 25.0% (n = 19), and multiple microorganisms in 3.9% (n = 3) neonates. The most commonly detected organisms were Staphylococcus aureus (29%) and Staph. epidermis (27%), followed by Escherichia coli (8%). Neisseria gonorrhea (8%), Moraxella catarrhal (5%), Streptococcus pneumoniae (4%), Haemophilus influenza (4%), and Chlamydia trachomatis (1%). The main risk factors for severe ON were obstruction of the nasolacrimal duct (χ2 = 10.794, P = 0.001), meconium aspiration syndrome (χ2 = 6.252, P = 0.012), and cesarian section (χ2 = 5.118, P = 0.024). Neonatal ocular prophylaxis was a protective factor for severe conjunctivitis (χ2 = 6.905, P = 0.009). CONCLUSIONS: Staphylococcus is the most common pathogen of severe ON. Nasolacrimal duct obstruction (NLDO) is a risk factor for ON.

Ophthalmia neonatorum in a tertiary referral children's hospital: A retrospective study.

OBJECTIVES: The purpose of this study was to examine the aetiology, investigation and management of ophthalmia neonatorum (ON) presenting to a tertiary referral children's hospital over 5 years. METHODS: The eye swab data of all neonates presenting to Children's Health Ireland at Temple Street (Dublin, Ireland) between 1st January 2013 and 3rd September 2018 was analysed. The medical records of all patients with positive eye swab results were retrospectively reviewed. RESULTS: A total of 157 neonates had positive eye swab results. 54 cases were identified as ON. Chlamydia trachomatis (20.4%) was the most common organism identified, followed by Staphylococcus aureus (18.5%), Haemophilus influenzae (14.8%), Moraxella catarrhalis (7.4%), Streptococcus pneumoniae (5.6%), Escherischia coli (3.7%), Klebsiella pneumoniae (1.9%) and Pseudomonas aeruginosa (1.9%). A bacterial culture swab was tested in all cases (100%), a C. trachomatis/N. gonorrhoeae PCR swab in 70.4% and a viral PCR swab in 35.2%. On subanalysis of the cases that had C. trachomatis/N. gonorrhoeae PCR testing, C. trachomatis was responsible for 28.9% of cases. 50% of cases were hospitalised, intravenous antibiotics were administered in 46.3% and macrolide therapy was prescribed in 38.9%. CONCLUSIONS: C. trachomatis was the most common cause of ON in this study and may be responsible for an even higher proportion of cases due to incomplete testing. In keeping with studies in different populations, S. aureus, H. influenzae and S. pneumoniae were also common. As a result, an improved management algorithm for cases of ON has been introduced in this centre.

OPHTHALMIA NEONATORUM in Italy: it is time for change.

Ophthalmia neonatorum (ON) refers to any conjunctivitis occurring in the first 28 days of life. In the past Neisseria gonorrhoeae was the most common cause of ON. It decreased with the introduction of prophylaxis at birth with the instillation of silver nitrate 2% (the Credè's method of prophylaxis). Today, the term ON is used to define any other bacterial infection, in particular due to Chlamydia Trachomatis. Currently, the WHO reccomends topical ocular prophylaxis for prevention of gonococcal and chlamydial conjunctivitis for all neonates. On the contrary, several European countries no longer require universal prophylaxis, opting for screening and treatment of pregnant women at high risk of infection. And what about Italy? Have a look on Italian history of prophylaxis, starting by the first decree issued in 1940, signed by Benito Mussolini. In the following decades the law has undergone many changes. At the moment, legislation is unclear, therefore careful consideration is required in order to draft the correct appoach.

Culture Positive Cases of Ophthalmia Neonatorum in a Tertiary Care Centre of Nepal: A Descriptive Cross-sectional Study.

INTRODUCTION: Ophthalmia neonatorum although runs a benign course mostly, sometimes may progress to sight threatening complications. The study was conducted to find the prevalence of culture positive cases of opthalmia neonatorum. METHODS: It was a descriptive cross-sectional study conducted at a tertiary care center from January to December 2019. Ethical clearance was obtained from institutional review committee of Kathmandu Medical College. Convenience sampling was done. All data were entered into excel and, then for analysis, exported to Statistal Package for Social Sciences version 21. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: The prevalence of culture positive cases of opthalmia neonaturum is 10 (55.55%) (32.61-78.49 at 95% Confidence Interval). The causative organisms were coagulase negative Staphylococcus 4 (40%), Staphylococcus aureus 3 (30%), Klebsiella 2 (20%) and Pseudomonas 1 (10%). Culture sensitivity of the isolated organisms were different according to the patient even in case of the same organism. Vancomycin 7 ( 70%) was the most sensitive antibiotic followed by Ciprofloxacin 6 (60%), Amikacin 5 (50%) and Cloxacillin 5 (50%) while Azithromycin 1 (10%), Cefixime 1 (10%) and Cotrimoxazole 1 (10%) were the least sensitive. CONCLUSIONS: Staphylococcus species was the most common organism isolated from neonates with ophthalmia neonatorum and vancomycin was the most sensitive antibiotic.

Ophthalmia neonatorum as the presenting sign of SARS-CoV-2.

The most common ocular manifestation of SARS-CoV-2 in adults and children is acute conjunctivitis. We report the case of a 4-day-old infant who presented with acute-onset mucopurulent discharge of the left eye as well as subconjunctival hemorrhage and palpebral injection, without corneal findings. A diagnosis of ophthalmia neonatorum was established, for which ocular cultures and Gram staining were performed. No bacterial growth was noted, and polymerase chain reaction (PCR) testing for Chlamydia trachomatis, Neisseria gonorrhea, and herpes simplex were negative. Nasopharyngeal and conjunctival SARS-CoV-2 PCR were positive. Given the identification of SARS-CoV-2 illness, lack of other underlying bacterial or viral etiology on testing, and the well-documented ability for SARS-CoV-2 to cause conjunctivitis, the clinical picture was supportive of ophthalmia neonatorum secondary to SARS-CoV-2. The infant was treated with ceftriaxone and azithromycin prior to culture results. During admission, no systemic findings of Covid-19 illness were observed.

Adverse pregnancy and neonatal outcomes associated with Neisseria gonorrhoeae: systematic review and meta-analysis.

OBJECTIVE: To examine associations between Neisseria gonorrhoeae (NG) infection during pregnancy and the risk of preterm birth, spontaneous abortion, premature rupture of membranes, perinatal mortality, low birth weight and ophthalmia neonatorum. DATA SOURCES: We searched Medline, EMBASE, the Cochrane Library and Cumulative Index to Nursing and Allied Health Literature for studies published between 1948 and 14 January 2020. METHODS: Studies were included if they reported testing for NG during pregnancy and compared pregnancy, perinatal and/or neonatal outcomes between women with and without NG. Two reviewers independently assessed papers for inclusion and extracted data. Risk of bias was assessed using established checklists for each study design. Summary ORs with 95% CIs were generated using random effects models for both crude and, where available, adjusted associations. RESULTS: We identified 2593 records and included 30 in meta-analyses. Women with NG were more likely to experience preterm birth (OR 1.55, 95% CI 1.21 to 1.99, n=18 studies); premature rupture of membranes (OR 1.41, 95% CI 1.02 to 1.92, n=9); perinatal mortality (OR 2.16, 95% CI 1.35 to 3.46, n=9); low birth weight (OR 1.66, 95% CI 1.12 to 2.48, n=8) and ophthalmia neonatorum (OR 4.21, 95% CI 1.36 to 13.04, n=6). Summary adjusted ORs were, for preterm birth 1.90 (95% CI 1.14 to 3.19, n=5) and for low birth weight 1.48 (95% CI 0.79 to 2.77, n=4). In studies with a multivariable analysis, age was the variable most commonly adjusted for. NG was more strongly associated with preterm birth in low-income and middle-income countries (OR 2.21, 95% CI 1.40 to 3.48, n=7) than in high-income countries (OR 1.38, 95% CI 1.04 to 1.83, n=11). CONCLUSIONS: NG is associated with a number of adverse pregnancy and newborn outcomes. Further research should be done to determine the role of NG in different perinatal mortality outcomes because interventions that reduce mortality will have the greatest impact on reducing the burden of disease in low-income and middle-income countries. PROSPERO REGISTRATION NUMBER: CRD42016050962.

Prophylaxis for ophthalmia neonatorum in Brazil: A snapshot using a multi-professional national survey.

BACKGROUND: Brazil is a large country with an elevated incidence of Chlamydiatrachomatis (CT) and Neisseriagonorrhoeae (NG) during pregnancy and variable access to health care. The objective of the study was to identify ophthalmia neonatorum prophylaxis practices in the country. METHODS: A prospective multidisciplinary survey was conducted using a closed social media group. Fifteen questions were developed after literature review. Specific content included categorization of respondents and practices such as type of medication, age at administration, occurrence of clinical and/or chemical conjunctivitis and microbiology identification. Questions were multiple choice, but some allowed written response. RESULTS: A total of 1.015 professionals responded, representing 24 states (92%) and 181 cities; mainly neonatologists (64%) and general pediatricians (21%). 96% of respondents reported performing prophylaxis at their institutions, mostly at birth or <1 h of life (99%), and regardless the mode of delivery (73%). Frequently used medications are: 1% silver nitrate (64%), 2.5% povidone iodine (18%) or 10% silver vitelinate (12%), with some regional variations. Occurrence of chemical conjunctivitis was stated by 58% of the respondents and microbiology identification was unusual. CONCLUSIONS: Ophthalmia neonatorum prophylaxis Brazil is almost universal and mainly performed by the use of anti-septic medications, with some regional variability. However, identification and treatment of CT and NG in both parents and newborns is not accomplished.
