Abstract

In infants and toddlers (N = 8) with infantile spasms, visual and somatosensory evoked potentials (VEP, SEP) were recorded during the course of the illness. During hypsarrhythmia the pattern evoked potential was missing (7/8) or grossly abnormal (1/8), indicating functional amaurosis. Flash evoked responses were normal in 50% even during the EEG-status, showing the superiority of pattern versus flash evoked potentials for visual functions in infancy. The alterations were reversible after successful treatment. Early SEP-components remained normal even during the bioelectrical status but later cortical components were altered in a reversible manner. The results show the objective state of functional sensory block during the EEG-status and underline the necessity of quick and effective treatment to avoid delayed visual maturation.

Safety of a quadrivalent meningococcal conjugate vaccine (MenACYW-TT) administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in USA and Puerto Rico: Results from a Phase III, randomized, active-controlled study.

MenACYW-TT, a quadrivalent meningococcal tetanus toxoid-conjugate vaccine, is approved for prevention of invasive meningococcal disease in infants ≥ 6 weeks of age in the USA. This Phase III study (NCT03673462; September 17, 2018 - March 16, 2023) evaluated the safety of MenACYW-TT compared with a licensed quadrivalent meningococcal oligosaccharide diphtheria CRM197-conjugate vaccine (MenACWY-CRM) when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in a four-dose series (3+1 schedule). Participants were randomized 3:1 to receive MenACYW-TT (Group 1; n = 2080) or MenACWY-CRM (Group 2; n = 697) at 2, 4, 6, and 12 months of age, with concomitant administration of routine pediatric vaccines (DTaP5-IPV/Hib, PCV13, rotavirus, hepatitis B, MMR, and varicella vaccines). Safety assessments included immediate unsolicited adverse events within 30 minutes post-vaccination, solicited injection site and systemic reactions within 7d, unsolicited AEs within 30d, serious adverse events (SAEs) including adverse events of special interest (AESIs), and medically attended adverse events (MAAEs) throughout the study. MenACYW-TT and MenACWY-CRM were overall well tolerated, and safety profiles were comparable. Solicited injection site reactions occurred in 84.9% and 84.6% of participants in Groups 1 and 2, respectively; solicited systemic reactions in 87.1% and 88.2%, respectively. During the entire study, 5.2% in Group 1 and 3.0% in Group 2 experienced at least one SAE; 0.9% and 0.1%, respectively, reported at least one AESI. Three deaths occurred in Group 1. All SAEs, AESIs, and deaths were unrelated to study vaccines. This study supports the safety profile of MenACYW-TT in infants and toddlers aged ≥ 6 weeks.Study registration: Clinicaltrials.gov: NCT03673462; EudraCT: 2019-004459-35.

Two new cases of fragile X syndrome without CGG triplet expansion. Clinical-molecular characterization and review of the literature.

Fragile X syndrome (FXS) is classically caused by CGG repeat expansion in the FMR1 gene leading to gene silencing. We describe two unrelated patients with clinical features consistent with FXS but harbouring distinct molecular mechanisms. The first patient had a pathogenic intronic variant in FMR1, predicted to impair protein function, and no repeat expansion. The second patient carried a complete deletion of the FMR1 gene, resulting in loss of gene expression. Both individuals presented with developmental delay, intellectual disability, and behavioural manifestations typical of FXS. These cases expand the causal heterogeneity underlying a clinically recognizable phenotype. They reinforce the concept that comprehensive molecular testing beyond repeat expansion analysis is mandatory in individuals with a strong clinical suspicion of FXS, in absence of a typical CGG triplet expansion.

Unveiling clinical and genetic landscapes of MMA and CBS: insights from whole exome sequencing in a tertiary care setting.

BACKGROUND: MMA and CBS deficiency are rare autosomal recessive metabolic disorders caused by defects in cobalamin metabolism and cystathionine-beta-synthase activity, respectively. Advanced molecular genetic techniques, have become essential for diagnosing these conditions. This study aimed to analyze the genetic variations in three MMA and four CBS deficiency cases using WES and correlate the findings with clinical, biochemical, and treatment outcomes. METHODS: Clinical evaluation, biochemical testing, neuroimaging, and WES were performed. WES data were analyzed using the reference genome GRCh37, and variants were classified according to ACMG guidelines. Treatment outcomes were monitored for three months post-intervention. RESULTS: In MMA cases, a homozygous pathogenic variant (c.394 C > T, p.Arg132Ter) in MMACHC was identified in all three patients. Biochemical abnormalities included methylmalonic aciduria, elevated homocysteine, and megaloblastic anemia. Hydroxycobalamin therapy improved behavioral, cognitive, and dermatological symptoms, though residual neuropathy persisted in one case. In CBS deficiency, pathogenic variants in CBS (c.992 C > T, p.Ala331Val; c.862 G > A, p.Ala288Thr; c.700 G > A, p.Asp234Asn) were identified. Clinical features included developmental delayed milestones, lens dislocation, and vascular complications. Treatment outcomes varied based on early diagnosis and compliance. CONCLUSION: This study highlights the importance of newborn screening program with WES in diagnosing and managing MMA and CBS deficiency, facilitating early intervention, improving clinical outcomes, and supporting precision medicine approaches. IMPACT: Early newborn screening and diagnosis are critical for effective treatment and improved patient outcomes. Novel clinical and pathogenic variants will expand the current understanding of these disorders. WES enhances the diagnostic precision for MMA and CBS deficiency, facilitating timely intervention and superior clinical management. Accurate and early detection of treatable IEMs through NBS can significantly reduce disease burden and healthcare costs.
