Safety monitoring of bivalent mRNA COVID-19 vaccine among pregnant persons in the vaccine adverse event reporting System - United States, September 1, 2022 - March 31, 2023.

BACKGROUND: Pregnant persons are at increased risk of severe COVID-19 illness. Bivalent mRNA COVID-19 vaccination is recommended for everyone, including pregnant persons. However, data are limited on the safety of bivalent mRNA COVID-19 vaccination during pregnancy. OBJECTIVE: To evaluate and summarize reports to the Vaccine Adverse Event Reporting System (VAERS), a national spontaneous reporting system, among pregnant persons who received bivalent mRNA COVID-19 vaccine. METHODS: VAERS U.S. reports of adverse events (AEs) in pregnant persons who received the bivalent mRNA COVID-19 vaccine from 9/1/2022-03/31/2023 were identified. Clinicians reviewed all reports and available medical records. AEs of these reports were compared with AEs reported to VAERS following monovalent mRNA COVID-19 booster vaccination in pregnancy. RESULTS: VAERS received 136 reports for pregnant persons who received bivalent mRNA COVID-19 vaccine; 87 (64 %) after BNT162b2 (Pfizer-BioNTech), and 48 (35 %) after mRNA-1273 (Moderna); 28 (20.6 %) reports were classified as serious. The most common pregnancy-specific outcomes reported included 12 (8.8 %) spontaneous abortions (<20 weeks gestation), 6 (4.4 %) episodes of preterm delivery, and 5 (3.7 %) reports of preeclampsia. One stillbirth (≥20 weeks gestation) was reported. No maternal or infant deaths were reported. There were 6 reports of AEs in infants, which included 3 reports of admissions to the neonatal intensive care unit: two infants with low birth weight, and one infant with a patent ductus arteriosus and patent foramen ovale. Non-pregnancy-specific adverse events were mostly COVID-19 infection and systemic reactions (e.g., headache, fatigue). Pregnancy-specific conditions were reported less frequently after bivalent mRNA COVID-19 vaccination compared to monovalent mRNA COVID-19 booster vaccination (3rd and 4th dose). CONCLUSIONS: Based on this review of reports to VAERS, the safety profile of bivalent mRNA COVID-19 vaccination in pregnant persons was comparable to that observed for monovalent mRNA COVID-19 booster vaccination (3rd and 4th dose) in pregnant persons.

COVID-19 vaccine safety inquiries to the centers for disease control and prevention immunization safety office.

BACKGROUND: Following the authorization and recommendations for use of the U.S. COVID-19 vaccines, the Centers for Disease Control and Prevention (CDC)'s Immunization Safety Office (ISO) responded to inquiries and questions from public health officials, healthcare providers, and the general public on COVID-19 vaccine safety. METHODS: We describe COVID-19 vaccine safety inquiries, by topic, received and addressed by ISO from December 1, 2020-August 31, 2022. RESULTS: Of the 1978 COVID-19 vaccine-related inquiries received, 1655 specifically involved vaccine safety topics. The most frequently asked-about topics included deaths following vaccination, myocarditis, pregnancy, and reproductive health outcomes, understanding or interpreting data from the Vaccine Adverse Event Reporting System (VAERS), and thrombosis with thrombocytopenia syndrome. CONCLUSIONS: Inquiries about vaccine safety generally reflect issues that receive media attention. ISO will continue to monitor vaccine safety inquiries and provide accurate and timely information to healthcare providers, public health officials, and the general public.

Acute and early developmental outcomes of children with Duarte galactosemia.

A recent study demonstrated that children with Duarte galactosemia (DG) do not show increased prevalence of detectable developmental complications when 6-12 years old. However, that study left unanswered whether infants with DG might be at increased risk for acute problems when drinking milk or whether children with DG younger than 6 years might show increased prevalence of perhaps transient developmental challenges. Here, we have addressed both of these questions by analyzing parent/guardian-reported data collected retrospectively for 350 children, 206 with DG and 144 unaffected siblings from the same families. The variables analyzed included whether each child had experienced (1) acute complications in infancy, (2) early intervention services when <3 years old, and/or (3) special educational services when 3-5 years old. For each case-control comparison, or case-by-diet comparison, we used logistic regression that included the following potential covariates: age, sex, race, family income, and parent education, as appropriate. We found that none of the three outcome variables tested showed significant differences between cases and controls, or among cases as a function of galactose exposure in infancy. To the limits of our study, we therefore conclude that regardless of whether a child with DG drinks milk or low-galactose formula as an infant, they are not at increased risk for acute complications or early childhood developmental challenges that require intervention.

Feasibility of Social Media Recruitment for Orofacial Cleft Genetic Research.

OBJECTIVE: This study assessed the feasibility of unpaid social media advertising to recruit participants affected with an orofacial cleft (OFC) for a genetic study. DESIGN: This is a retrospective analysis of recruitment based on enrollment and participation in a genetic study. Participants completed a series of enrollment surveys, provided saliva samples, and completed postparticipation feedback surveys. PARTICIPANTS: Participants were eligible if they or a minor in their care were affected by an OFC, the affected participant was not adopted, and the mother of the affected individual had not taken antiseizure medication during pregnancy. MAIN OUTCOME MEASURES: Success of recruitment was evaluated from the number of enrolled participants and sample return rate. RESULTS: In the first 12 months of recruitment, 313 individuals completed initial screening surveys; of these, 306 participants were eligible. A total of 263 individuals completed all online surveys and were sent DNA sample kits. One hundred sixty-two subject DNA samples were returned within 12 months of sending, for a return rate of 62%. Approximately two-thirds (66.3%) of all returned samples were sent back within the first 6 weeks after receiving DNA kits. CONCLUSIONS: Unpaid social media advertising enabled the recruitment of a large cohort of participants in a short time (12 months). The resulting study population was limited in racial and ethnic diversity, suggesting that other recruitment strategies will be needed for studies seeking specific demographic or socioeconomic groups. Nonetheless, social media recruitment was efficient and effective for recruiting participants for a genetic study in comparison to traditional clinic-based modes of recruitment.

Hand fine motor control in classic galactosemia.

Classic galactosemia (CG) is a rare inborn error of metabolism that results from profound deficiency of galactose-1-P uridylyltransferase (GALT). Despite early detection and rapid and lifelong dietary restriction of galactose, which is the current standard of care, most patients grow to experience a broad range of complications that can include motor difficulties. The goal of this study was to characterize hand fine motor control deficit among children and adults with classic galactosemia (CG). Specifically, we used Neuroglyphics software to collect digital Archimedes spiral drawings on a touch screen from 57 volunteers with CG (cases) and 80 controls. Hand fine motor control was scored as root mean square (RMS) of spirals drawn relative to an idealized template. Presence of tremor was defined as a peak in periodicity of changes in drawing speed or direction in the 4-8 Hz range. We observed a highly significant difference (P < .001) in RMS scores between cases and controls, with almost 51% of cases showing at least 1 of 4 spirals scoring outside the 95th percentile for controls. The corresponding prevalence for controls was 10%. Similarly, more than 35% of cases, and almost 14% of controls, showed at least 1 of 4 spirals with a tremor amplitude above the 95th % cutoff for controls. Our results both confirm and extend what is known about hand fine motor control deficit among children and adults with CG and establish digital assessment as a useful approach to quantify this outcome.

Deep phenotyping in 3q29 deletion syndrome: recommendations for clinical care.

PURPOSE: To understand the consequences of the 3q29 deletion on medical, neurodevelopmental, psychiatric, brain structural, and neurological sequalae by systematic evaluation of affected individuals. To develop evidence-based recommendations using these data for effective clinical care. METHODS: Thirty-two individuals with the 3q29 deletion were evaluated using a defined phenotyping protocol and standardized data collection instruments. RESULTS: Medical manifestations were varied and reported across nearly every organ system. The most severe manifestations were congenital heart defects (25%) and the most common were gastrointestinal symptoms (81%). Physical examination revealed a high proportion of musculoskeletal findings (81%). Neurodevelopmental phenotypes represent a significant burden and include intellectual disability (34%), autism spectrum disorder (38%), executive function deficits (46%), and graphomotor weakness (78%). Psychiatric illness manifests across the lifespan with psychosis prodrome (15%), psychosis (20%), anxiety disorders (40%), and attention deficit-hyperactivity disorder (ADHD) (63%). Neuroimaging revealed structural anomalies of the posterior fossa, but on neurological exam study subjects displayed only mild or moderate motor vulnerabilities. CONCLUSION: By direct evaluation of 3q29 deletion study subjects, we document common features of the syndrome, including a high burden of neurodevelopmental and neuropsychiatric phenotypes. Evidence-based recommendations for evaluation, referral, and management are provided to help guide clinicians in the care of 3q29 deletion patients.

Developmental Outcomes in Duarte Galactosemia.

: media-1vid110.1542/5849572227001PEDS-VA_2018-2516Video Abstract OBJECTIVES: For decades, infants with Duarte galactosemia (DG) have been identified by newborn screening (NBS), but whether they should be treated with dietary restrictions of galactose has remained unknown. To clarify, we conducted a study of dietary and developmental outcomes in 206 children with DG (case patients) and 144 controls, all of whom were 6 to 12 years old. METHODS: We recruited case patients from states where they were identified by NBS; unaffected siblings served as controls. Diet in infancy was ascertained by retrospective parent surveys; developmental outcomes were assessed in 5 domains, yielding 73 outcome measures for each child. We divided subjects randomly into independent discovery (n = 87) and validation (n = 263) sets. We tested the discovery set to order the 73 outcome measures by ascending P values and tested the 10 outcomes with the lowest P values for possible association with DG in the validation set. We also tested these same 10 outcomes for possible association with milk exposure in infancy among case patients in the validation set. RESULTS: None of the 73 outcomes tested in the discovery set revealed significant association with DG, and none of the 10 outcomes tested in the validation set revealed either significant association with DG or significant association with milk exposure among children with DG. CONCLUSIONS: Through our results, we demonstrated that there were no significant differences in outcomes tested between case patients and controls or among case patients as a function of milk exposure in infancy. In this study, we provide a long-needed foundation of knowledge for health care providers, families, and NBS professionals seeking to make evidence-based decisions about DG.

Presentation, progression, and predictors of ovarian insufficiency in classic galactosemia.

Classic galactosemia (CG) is an inherited metabolic disorder that affects about 1 in 50,000 live births in the United States and many other countries. With the benefit of early detection by newborn screening and rapid dietary restriction of galactose, generally achieved by removing dairy from the diet, most affected infants are spared the acute and potentially lethal symptoms of disease. Despite early detection and life-long dietary intervention, however, most patients grow to experience a constellation of long-term complications that include premature ovarian insufficiency in the vast majority of girls and young women. Our goal in the study reported here was to define the presentation, progression, and predictors of ovarian insufficiency in a cohort of 102 post-pubertal girls and women with CG. To our knowledge, this is the largest cohort studied to date. We found that 68% of the girls and women in our study achieved spontaneous menarche, while 32% achieved menarche only after starting hormone replacement therapy (HRT). Of those who achieved spontaneous menarche, fewer than 50% were still cycling regularly after 3 years, and fewer than 15% were still cycling regularly after 10 years. Of factors tested for possible association with spontaneous menarche, only detectable (≥ 0.04 ng/mL) plasma anti-Müllerian hormone (AMH) level was significant. These results extend substantially from prior studies and confirm that detectable plasma AMH is a useful predictor of ovarian function in girls and women with CG.
