A Case Report of a Suspected Neonatal Alloimmune Thrombocytopenia in a Tertiary Health Institution

Fetal and neonatal alloimmune thrombocytopenia FNAIT is the leading cause of severe thrombocytopenia in the fetus and neonate leading to serious bleeding, intracranial haemorrhage and death and also intracranial haemorrhage in full-term infants.

We reported a case of a 33-year-old woman who was delivered of a male neonate via Emergency lower segment Cesarean section CS on account of premature rupture of the membrane with oligo hydramnios at an estimated gestational age EGA of 29 weeks 3 days. Her blood group is O Rhesus D positive, and Genotype HbAA. No known premorbid illness. Her last confinement was of a male child delivered via CS and died within 12 hours of birth.

This reported case of suspected FNAIT was a baby received alive after CS with birthweight of 1,060g and APGAR score of 7185 transiently, and was noticed to be bleeding from the mouth and anus shortly after birth. Thereafter, he had thrombocytopenia, persistent anaemia, several apneic attacks, seizures, desaturation and died after 42 hours of life despite all prompt clinical interventions. Autopsy summary includes anaemia, central cyanosis, petechial hemorrhage, diffuse alveolar damage, cerebral edema, acute tubular necrosis, small for gestational age and placental vasculopathy.

Conclusion: Fetal and neonatal alloimmune thrombocytopenia is a rare disorder and yet poses a challenging diagnosis and treatment plan in resource-limited centres especially in developing countries. Although the clinical findings of the reported suspected case were not classical as previously reported by other studies, they’re pointers to our curiosity and open to further criticism.
