Brief summary

Applying the ISTH-BAT questionnaire on Egyptian patients with type I VWD aiming to correlate the BS with the laboratory findings

Detailed description

The clinical phenotype of the disease is variable and tends to be mild in type 1 vWD, whereas it shows serious bleeding manifestations in types 2 and 3. Overall, the symptoms reported in vWD include easy bruising, epistaxis, gastrointestinal bleeding, excessive menstrual bleeding, postpartum haemorrhage, and excessive bleeding after surgical operation and minor wounds.However, A distinctive bleeding history is a prerequisite for the diagnosis of any bleeding disorder and should guide further laboratory investigations In an attempt to standardize the diagnostic criteria of VWD, a bleeding questionnaire and a bleeding score were developed The combination of a standardized bleeding questionnaire and a well-defined interpretation grid (for the computation of the final (BS) has been referred to as a Bleeding Assessment Tool (BAT).
