Neonatal Presentation of Severe Hemophilia A: An Original Case Report and a Literature Review

Children (Basel). 2024 Nov 6;11(11):1352. doi: 10.3390/children11111352.

ABSTRACT

Introduction: We report the case of a neonate diagnosed with severe hemophilia A (HA) and conduct a literature review of cases of severe HA presenting at the neonatal age to help define the clinical diagnostic findings and existing differences between the sporadic and familial onset of this condition. Report of a Case: A 6-day-old newborn presented with worsening pallor, inappetence, and hyporeactivity for 48 h. The diagnosis was severe hemophilia A (HA), leading to an unfavorable outcome. A literature review focusing on case reports and series focusing on the clinical expression of HA in neonates was conducted, documenting clinical presentation, family history, and outcomes. Literature review: Forty patients were included. HA was observed in five cases (12.5%) of very preterm births (≤32 weeks) and in four cases (10%) of moderately or late preterm births. Seventeen patients (43%) had a family history, with inheritance being sporadic (21 newborns, 53%) or acquired (2 cases, 4%). Clinical onset typically occurred within the first week of life (approximately 8 out of 10 cases), while only three cases (7.5%) had onset after the first month. Inherited cases presented with hemorrhagic states (nine cases), hypovolemic shock (five cases), or intracranial hypertension (two cases). Sporadic cases showed localized bleeding (11 cases), hypovolemic shock (5 cases), or neurological symptoms like seizures and anisocoria (5 cases). Acquired cases included severe intracranial hemorrhage in one case. Conclusions: Neonatal HA can manifest with severe symptoms and rapid progression, making early diagnosis crucial. Non-specific signs and the absence of coagulophaty disorders in family history can delay diagnosis. Symptoms like prolonged bleeding, cutaneous hematomas, or intracranial bleeding necessitate ruling out major coagulopathy, and neurological signs require immediate imaging to exclude intracranial bleeding.
