If the delivery has been planned then antigen negative platelets should be available in case the infants platelet count is low on a cord blood sample. After birth
The most rapidly effective treatment in infants with severe hemorrhage and/or a very low platelet count (<30,000  μL−1) is the transfusion of compatible platelets (i.e. platelets from a donor who, like the mother, lacks the causative antigen). If  antigen negative platelets are unavailable, then standard neonatal platelet transfusions should be given until antigen negative platelets become available. If a platelet transfusion is not available immediately then the infant can be given IVIG (1g/kg) however, this will have no effect on the platelet count before 24 to 72 hours.A platelet transfusion is required immediately if there is severe or life-threatening bleeding. If life-threatening bleeding occurs, for example an intracranial hemorrhage, then the platelet count needs to be increased to decrease the risk of further bleeding (> 100,000  μL−1).Any infant with suspected NAIT should have an ultrasound of the head within the first 24 hours after birth to make sure that there is no evidence of an intracranial hemorrhage.If the infant has a platelet count >30,000  μL−1 and no evidence of bleeding, then the baby can be monitored with blood counts until the blood counts return to normal, without the need for any additional treatment. In the past, infusions of IVIG (1 g/kg/day for two days) have been given to the infant and have been shown to rapidly increase the platelet count.
Acropachy is a dermopathy associated with Graves disease. It is characterized by soft-tissue swelling of the hands and clubbing of the fingers. Radiographic imaging of affected extremities typically demonstrates periostitis, most commonly the metacarpal bones. The exact cause is unknown, but it is thought to be caused by stimulating auto-antibodies that are implicated in the pathophysiology of Graves thyrotoxicosis. There is no effective treatment for acropachy. Since it is closely associated with Graves disease, it is associated with other manifestations of Graves disease, such as Graves ophthalmopathy and thyroid dermopathy.Hereditary acropachy (also known as "isolated congenital nail clubbing") may be associated with HPGD.
