Final answer:
A 15-year-old female with recurrent epistaxis, heavy menses, petechiae, and abnormal clotting tests likely has von Willebrand disease. Treatments include desmopressin acetate (DDAVP) and VWF-containing concentrates to improve clotting function.
Step-by-step explanation:
The patient, a 15-year-old female, presenting with recurrent epistaxis, heavy menses, petechiae, normal platelet count, increased bleeding time, and prolonged partial thromboplastin time (PTT) is suggestive of a bleeding disorder. Given these symptoms and laboratory findings, the most likely diagnosis is von Willebrand disease, which is a genetic disorder caused by a deficiency or dysfunction of von Willebrand factor (VWF), a critical clotting protein.
Treatment for von Willebrand disease typically involves managing symptoms and improving clotting function. Two common treatments are desmopressin acetate (DDAVP), which can stimulate the body to release more von Willebrand factor and factor VIII, and VWF-containing concentrates, which can be infused to replace missing von Willebrand factor.
