Abstract
Retinopathy of prematurity (ROP) and necrotising enterocolitis (NEC) are complications of prematurity. Despite being quite different in terms of incidence, pathogenesis and consequences, both share a pathogenic role of aberrant vascularisation: increased in ROP, deficient for NEC. Current therapy for ROP includes the use of anti-vascular endothelial growth factor (anti-VEGF) agents, which are able to interrupt retinal hypervascularity. Despite being delivered intravitreously, anti-VEGF used in ROP can be absorbed into circulation and exert systemic effects. We present here a case of an ex-27 weeks gestational age infant, presenting multiple NEC risk factors, treated at 2 months of age with low-dose ranibizumab, who developed a large bowel NEC episode in the first week after treatment. We believe that this further report of an association between anti-VEGF agents and NEC could be interesting for the identification of children at risk of severe adverse events and stimulating further research on the topic.

Neurodevelopmental Outcomes for Retinopathy of Prematurity: A Taiwan Premature Infant Follow-up Network Database Study. Am J Ophthalmol 2023; 247:170-180. [PMID: 36343698 DOI: 10.1016/j.ajo.2022.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 10/29/2022] [Accepted: 10/29/2022] [Indexed: 11/06/2022]
Abstract
PURPOSE To evaluate the neurodevelopmental outcomes in premature infants who received intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections to treat retinopathy of prematurity (ROP). DESIGN Retrospective cohort study. METHODS This study was conducted using the database from the Taiwan Premature Infant Follow-up Network. Demographic data, systemic risk factors, ROP status, and neurodevelopmental assessment using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) were collected. Patients were divided into 4 groups: prematurity without ROP, ROP without treatment, ROP with laser treatment, and ROP with intravitreal anti-VEGF treatment. A generalized estimating equation was used for analyzing repeated measurements of Bayley-III at the corrected ages of 6, 12, and 24 months. RESULTS A total of 2090 patients with a mean gestational age of 31.2 weeks were included. The Bayley-III composite scores of patients with ROP treated with anti-VEGF were comparable to those of patients with ROP without treatment (cognitive: P = .491; language: P = .201; motor: P = .151) and premature patients without ROP (cognitive: P = .985; language: P = .452; motor: P = .169) after adjusting for confounders. Patients with ROP treated with laser photocoagulation exhibited poorer cognitive composite scores than did those without treatment (P < .001), premature patients without ROP (P < .001), and those treated with anti-VEGF (P < .001), but they had similar language and motor composite scores. CONCLUSIONS Intravitreal anti-VEGF treatment for ROP was not associated with adverse neurodevelopment in premature infants. Further studies are needed to determine whether general anesthesia or sedation used in laser treatment for ROP has significant impacts on neurodevelopmental outcomes.

Abstract
PURPOSE Retinopathy of prematurity (ROP) progression is an inter-play of various perinatal and neonatal angiogenic and inflammatory cytokines. A small subset of ROP progresses to ROP requiring treatment. The present study was conducted with the aim to determine whether levels of IL-6, IL-8 and VEGF in serum and urine at the time of first ROP screening visit could be a biomarker for the prediction of development of treatable ROP. METHOD Prospective single-center observational study of preterm babies screened for ROP. Blood and urine samples were collected as a part of routine sampling at initial ROP screening visit and stored at -80 °C for further processing. The babies were followed up and grouped into 'Group A' comprising of 35 babies who developed treatable ROP and 'Group B' comprising of 36 babies with regressed ROP or no ROP. The evaluation of blood and urine samples was done for IL6, IL8 and VEGF by solid-phase sandwich RayBio® Human ELISA kit. RESULTS The median serum values for IL-6, IL-8 and VEGF in Group A and Group B were 5.8 pg/ml (IQR 1.5,128.5) and 8.7 pg/ml (IQR 1.5,30.5), 55.9 pg/ml (IQR 28.0, 392.9) and 27.0 pg/ml (IQR 20.5,444.9) and 26.6 pg/ml (IQR 6.3, 39.4) and 30.0 pg/ml (IQR9.2,70.3), respectively. Group A had significantly increased levels of IL-8 (p < 0.05). However, AUROC curve for serum IL-8 demonstrated suboptimal discriminating ability. CONCLUSION Babies developing ROP requiring treatment had significantly increased levels of IL-8 in the serum at the time of initial screening. However, it could not serve as predictor for treatable ROP.

Abstract
Background. To explore clinical characteristics and treatment reasons for intravitreal injection of antivascular endothelial growth factor (anti-VEGF) drugs in the treatment of nontype 1 retinopathy of prematurity (ROP). Methods. A retrospective study was conducted to screen the nontype 1 ROP from the collected ROP patients who received intravitreal injections of anti-VEGF drugs in Henan Eye Hospital from September 2018 to June 2021. Results. A total of 138 ROP cases (262 eyes) were included in this study, including 39 cases (28.3%), 65 eyes (24.8%) that were the nontype 1 ROP. Compared with the type 1 ROP group, the nontype 1 ROP group had slightly later treatment time (39.8 ± 2.7 weeks vs 38.1 ± 2.6 weeks,
) and a higher proportion of fusion protein drugs (87.2% vs 54.5%,
). After intravitreal injection of anti-VEGF drugs, 27 eyes (41.5%) were cured and 38 eyes (58.5%) improved in the nontype 1 ROP group, without recurrence and aggravation cases. There were more lesions in zone II (63 eyes, 96.9%), with stage 2 (40 eyes, 61.5%) and stage 3 (23 eyes, 35.4%), and 58 eyes (89.2%) showed preplus in the nontype 1 ROP group. Treatment reasons included preplus in 58 eyes (89.2%), ridge aggravation in 22 eyes (33.8%), simultaneous treatment of the contralateral eye in 9 eyes (13.8%), no regression of lesions in the persistent stage 2 or 3 over PMA 44 weeks of follow-up in 8 eyes (12.3%), and logistical considerations in 4 eyes (6.2%). Conclusions. Considering some peculiar clinical characteristics, treatment by intravitreal injection of anti-VEGF drugs may be considered carefully for some nontype 1 ROP in critical conditions.

Abstract
The retinopathy of prematurity (ROP), a neovascular retinal disorder presenting in premature infants, is the leading causes of blindness in children. Currently, there is no approved drug therapy for ROP in the U.S., highlighting the urgent unmet clinical need for a novel therapeutic to treat the disease. Secretogranin III (Scg3) was recently identified as a disease-selective angiogenic factor, and Scg3-neutralizing monoclonal antibodies were reported to alleviate pathological retinal neovascularization in mouse models. In this study, we characterized the efficacy and safety of a full-length humanized anti-Scg3 antibody (hAb) to ameliorate retinal pathology in oxygen-induced retinopathy (OIR) mice, a surrogate model of ROP, by implementing histological and functional analyses. Our results demonstrate that the anti-Scg3 hAb outperforms the vascular endothelial growth factor inhibitor aflibercept in terms of efficacy and safety to treat OIR mice. Our findings support the development of anti-Scg3 hAb for clinical application.

Abstract
To investigate VEGF and Ang-2 level changes in the systemic circulation after laser photocoagulation in premature infants with ROP. Methods: Eleven infants (4 girls and 7 boys) had serum levels determined for VEGF and Ang-2, collected 1 day prior to and 7 days after ROP laser therapy. Serum levels of VEGF and Ang-2 were quantified by enzyme-linked immunosorbent assay (ELISA). Results: Serum VEGF levels were significantly lower at 7 days after laser therapy compared to that at 1 day prior to laser therapy (p = 0.045). Serum Ang-2 levels increased significantly at 7 days after laser therapy compared with that at 1 day prior to laser therapy (p = 0.046). Conclusions: Serum VEGF levels in patients with ROP were suppressed and Ang-2 levels elevated significantly after laser therapy. The results suggest that changes in VEGF and Ang-2 serum levels may reflect regression and treatment of ROP.

Abstract
PURPOSE OF REVIEW To review the literature regarding reactivation of retinopathy of prematurity (ROP) after treatment with antivascular endothelial growth factor (anti-VEGF) agents. RECENT FINDINGS Reactivation can occur after anti-VEGF or laser. Risk factors for reactivation include patient and disease-related factors. Various studies are evaluating the use of different anti-VEGF agents and reactivation rates. However, the definition of reactivation varies between studies. SUMMARY The literature has varied definitions of reactivation, which is often used interchangeably with recurrence. It is important to recognize features of reactivation of ROP to appropriately manage patients and conduct clinical trials. The International Classification of ROP 3rd edition has established a consensus guideline regarding terminology describing reactivation.

THE LANCET CHILD & ADOLESCENT HEALTH 2021; 5:698-707. [PMID: 34391532 DOI: 10.1016/s2352-4642(21)00195-4] [Citation(s) in RCA: 44] [Impact Index Per Article: 14.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 06/16/2021] [Accepted: 06/22/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Intravitreal injection of vascular endothelial growth factor (VEGF) inhibitors is increasingly used to treat retinopathy of prematurity (ROP) in the absence of evidence about long-term efficacy or safety. In this prespecified interim analysis of the RAINBOW extension study, we aimed to prospectively assess outcomes at age 2 years. METHODS RAINBOW was an open-label, randomised trial that compared intravitreal ranibizumab (at 0·1 mg and 0·2 mg doses) with laser therapy for the treatment of ROP in very low birthweight infants (<1500 g). Families of the 201 infants that completed the RAINBOW core study were approached for consent to enter the extension study, which evaluates treatment outcomes prospectively through to 5 years of age. At age 20-28 months corrected for prematurity, participants had ophthalmic, development, and health assessments. The primary outcome was the absence of structural ocular abnormalities; secondary outcomes included vision-related quality of life (reported by parents using the Children's Visual Function Questionnaire), development (assessed with the Mullen Scales of Early Learning), motor function, and health status. Investigator-determined ocular and non-ocular serious and other adverse events were recorded. This study is registered with ClinicalTrials.gov, NCT02640664. FINDINGS Between June 16, 2016, and Jan 22, 2018, 180 infants were enrolled in the RAINBOW extension study, and 153 (85%) were evaluated at 20-28 months of age. No child developed new ocular structural abnormalities. Structural abnormalities were present in one (2%) of 56 infants in the ranibizumab 0·2 mg group, one (2%) of 51 infants in the 0·1 mg group, and four (9%) of 44 infants in the laser therapy group. The odds ratio of no structural abnormality was 5·68 (95% CI 0·60-54·0; p=0·10) for ranibizumab 0·2 mg versus laser therapy, 4·82 (0·52-45·0; p=0·14) for ranibizumab 0·1 mg versus laser therapy, and 1·21 (0·07-20; p=0·90) for ranibizumab 0·2 mg vs 0·1 mg. High myopia (-5 dioptres or worse) was less frequent after 0·2 mg ranibizumab (five [5%] of 110 eyes) than with laser therapy (16 [20%] of 82; odds ratio 0·19, 95% CI 0·05-0·69; p=0·012). Composite vision-related quality of life scores seemed higher among the ranibizumab 0·2 mg group (mean 84, 95% CI 80-88) compared with laser therapy (77, 72-83; p=0·063). Mullen Scales T-scores for visual reception, receptive and expressive language were distributed similarly between the three trial groups and there were similar proportions of infants with motor and hearing problems among treatment groups. The proportion of infants with respiratory symptoms and Z scores of standing height, weight, and head circumference were similarly distributed in the treatment groups. There were no adverse events considered by the investigator to be related to the study intervention. INTERPRETATION 2-year outcomes following ranibizumab 0·2 mg for the treatment of ROP confirm the ocular outcomes of the original RAINBOW trial and show reduced high myopia, with possibly better vision-related quality of life. This treatment did not appear to affect non-ocular infant development. FUNDING Novartis Pharma AG.

Association of Systemic or Intravitreal Antivascular Endothelial Growth Factor (Anti-VEGF) and Impaired Wound Healing in Pediatric Patients: Collagen to the Rescue. J Wound Ostomy Continence Nurs 2021; 48:256-261.

Abstract
BACKGROUND Bevacizumab is a humanized monoclonal antibody to vascular endothelial growth factor (VEGF) that has been used as a systemic chemotherapy treatment of various malignancies in adults since 2000. It has been used for pediatric patients over the last decade. In addition, bevacizumab is used for neonatal intravitreal administration for retinopathy of prematurity, a major complication of preterm birth, characterized by incomplete and abnormal vascularization of the retina that can lead to retinal detachment and blindness without treatment. CASES The objective of this multiple case series is to report impaired wound healing seen in 3 adolescents and 1 premature neonate receiving bevacizumab and to propose collagen-based dermal template as a choice for the management of such wounds. The 3 adolescents were undergoing treatment of malignancies and developed wound healing complication within weeks of receiving anti-VEGF. The premature neonate experienced an extravasation and had a slow wound healing trajectory after receiving intravitreal administration of bevacizumab for retinopathy of prematurity. All wounds achieved closure following topical treatment with a collagen dermal template. CONCLUSION Use of bevacizumab is increasing in the pediatric population. Clinicians should be aware of compromised wound healing and higher likelihood of wound dehiscence after bevacizumab administration. We recommend waiting for at least 4 to 6 weeks between anti-VEGF administration (either systemic or vitreous) and elective surgical procedures, consistent with adult literature recommendations. If patient has an existing wound, we assert that bevacizumab should not be administered until that wound is healed. If wound healing is stalled, we recommend dermal template as a safe and effective accelerator of wound healing.

Abstract
Intravitreal anti-vascular endothelial growth factor (VEGF) agents have revolutionized the treatment of retinopathy of prematurity (ROP); however, there are concerns regarding the potential systemic complications caused by those treatments. This study aimed to determine the serum concentrations of cytokines in infants with ROP and to evaluate the changes in serum VEGF concentrations after intravitreal conbercept (IVC). Sixty infants with ROP treated with IVC 0.25 mg were included. Blood samples were collected before treatment as well as 1 week and 4 weeks after treatment. Serum levels of 45 types of cytokines were measured by a multiplex bead assay. We observed that IVC 0.25 mg in ROP patients suppressed the circulating levels of VEGF-A and VEGF-D as of 1 week after injection, and these growth factor levels returned to baseline at 4 weeks. No significant differences were observed in the serum levels of the other cytokines between baseline and 1 or 4 weeks after IVC.

Abstract
Retinopathy of prematurity (ROP) is a neovascular retinal disorder that occurs in infants born prematurely. Nowadays, ROP constitutes a leading cause of childhood blindness worldwide and for decades the standard of care has involved peripheral retinal ablation. However, this type of treatment requires the use of specialized equipment by well-trained physicians, has been associated with poor structural and visual outcomes in some preterm infants, and despite its adequate application, some cases of ROP may continue to progress. Therefore, the need for simpler and more efficient strategies made anti-vascular endothelial growth factor (anti-VEGF) medications an appealing option for treatment. Recently, the use of anti-VEGF agents for ROP has increased worldwide; nevertheless, this practice remains off-label, and there is a lack of information regarding its safety profile and the possibility of unfavorable long-term outcomes causes the utmost concern. This review updates the recent evidence regarding the systemic and ocular safety of anti-VEGF treatment for ROP.
