High incidence of intracranial haemorrhage in Egyptian children with congenital afibrinogenaemia.

INTRODUCTION: Intracerebral hemorrhage (ICH) is associated with high morbidity and mortality in patients with congenital afibrinogenaemia. Details on location of cerebral haemorrhage, management and neurological outcomes are lacking. METHODS: We performed a retrospective study on Egyptian children with congenital afibrinogenaemia who experienced ICH, in order to estimate frequency, symptoms and neurological outcomes. RESULTS: Among 58 children with congenital afibrinogenaemia treated on demand, 18 (31%) had an history of ICH (28 episodes). The first ICH occurred at a median age of 1 year (Q1-Q3 1-7 years). Impaired consciousness level, vomiting and seizures were the most common presenting symptoms. Spontaneous bleeding was associated with a more severe clinical presentation and worse neurological outcomes, including hydrocephaly and impaired cognitive development. Only half of ICH events (n = 14) were treated in less than 24 h from the onset of symptoms. Fibrinogen replacement by Fresh Frozen Plasma (FFP), cryoprecipitate or fibrinogen concentrates was administered in seven (25%), 19 (68%) and three (10%) ICH events, respectively. Overall, seven (25%) ICH occurring in four patients required a surgical intervention. After the ICH, six patients started secondary prophylaxis. The cumulative incidence of ICH at 10 years was 35% (95% CI 23-51) and at 20 years was 40% (95 CI% 26.7-58.8). CONCLUSION: In our cohort of children with congenital afibrinogenaemia, ICH was very frequent and associated with adverse neurological outcomes and death. Further studies are required to determine whether primary prophylaxis starting early in childhood is indicated after diagnosis.
