Platelet storage pool deficiency is a type of coagulopathy characterized by defects in the granules in platelets, particularly a lack of granular non-metabolic adenosine diphosphate.[3] Individuals with adenosine diphosphate deficient storage pool disease present a prolonged bleeding time due to impaired aggregation response to fibrillar collagen.[citation needed]
Symptoms and signs
The presentation (signs/symptoms) of an individual with platelet storage pool deficiency is as follows:[1]
- Unusual bleeding(after surgical procedure)
- Anemia
- Decrease mean platelet volume
- Myelodysplasia
Cause
The condition of platelet storage pool deficiency can be acquired or inherited (genetically passed on from the individuals parents[4]).[1] Some of the causes of platelet storage pool deficiency when acquired are:[1]
- Hairy-cell leukemia
- Cardiovascularbypass
Mechanism
In terms of the pathophysiology of platelet storage pool deficiency one must consider several factors including the human body's normal function prior to such a deficiency, such as platelet alpha-granules[citation needed] one of three types of platelet secretory granule[5]
Platelet α–granules are important in platelet activity, α–granules connect with
Diagnosis
The diagnosis of this condition can be done via the following:[1]
- Flow cytometry
- Bleeding time analysis
- Platelet aggregation functionstudy:
ADP | Epinephrine | Collagen | Ristocetin | |
---|---|---|---|---|
P2Y receptor defect[6] (including Clopidogrel) | Decreased | Normal | Normal | Normal |
Adrenergic receptor defect[6] | Normal | Decreased | Normal | Normal |
Collagen receptor defect[6] | Normal | Normal | Decreased or absent | Normal |
Normal | Normal | Normal | Decreased or absent | |
Decreased | Decreased | Decreased | Normal or decreased | |
Storage pool deficiency[7] | Absent second wave | Partial | ||
Aspirin or aspirin-like disorder | Absent second wave | Absent | Normal |
Types
This condition may involve the alpha granules or the dense granules.[8] Therefore, the following examples include:
- Platelet alpha-granules
- Dense granules
- δ-Storage pool deficiency[11]
- Hermansky–Pudlak syndrome[12]
- Chédiak–Higashi syndrome[13]
Treatment
Platelet storage pool deficiency has no treatment however management consists of
