Bernard-Soulier syndrome (BSS) belongs to one the rare hereditary platelet disorders.Bernard-Soulier syndrome chaterstically shows giant platelets and thrombocytopenia.Bernard-Soulier syndrome (BSS) was first discovered in 1948.Bernard-Soulier syndrome may be classified into 4 subtypes.Bernard-Soulier syndrome is the result of the absence or decreased expression of the GPIb/IX/V complex on the surface of the platelets.Bernard-Soulier syndrome may be caused by abnormality in the genes for glycoprotein Ib/IX/V.The prevalence of Bernard-Soulier syndrome is approximately 1 per 100,000 individuals worldwide.The initial laboratory test to be done is blood cell counts and blood smears.There are no established risk factors for Bernard-Soulier syndrome.There is sufficient evidence to recommend routine screening for Bernard-Soulier syndrome with newer technologies in current clinical practice.If left untreated, patients with Bernard-Soulier syndrome may progress to develop bleeding manifestations like mucocutaneous bleedings, prolonged bleeding.Patients with bernard soulier syndrome usually remarkable for dysfunctional platelets.There is no specific treatment for Bernard-Soulier syndrome, the mainstay of therapy is supportive care.
Historical Perspective
- Bernard-Soulier syndrome (BSS)/ Hemorrhage Parous thrombocytic dystrophy/ Congenital hemorrhagic parous thrombocytic dystrophy is very rare disease as few as only ~100 cases have been reported in the literature.[1]
- Bernard-Soulier syndrome (BSS) was first discovered in 1948 in a young male by Jean Bernard and Jean-Pierre Soulier who are hematologists from french.[2]
- Bernard-Soulier syndrome (BSS) follows autosomal recessive trait and often associated with consanguinity.[3][4]
- Nurden and Caen, In 1975 reported that platelets showed absence of major surface membrane glycoprotein complex.[5][6][7]
Classification
Bernard soulier syndrome may be classified into 4 subtypes[8][9][10][11][12][13]

---|---|---|---|---|
Bernard-Soulier syndrome, type A1 | 17p13.2 | Autosomal Recessive | GP1BA | 606672 |

Giant platelet disorder, isolated | 22q11.21 | Autosomal Recessive | GP1BB | 138720 |
Pathophysiology
- It is thought that Bernard-Soulier syndrome is the result of the absence or decreased expression of the GPIb/IX/V complex on the surface of the platelets.[14][15][16][17][18][19][20]
- The GPIb/IX/V complex is the receptor for von Willebrand factor (vWF).
- The GPIb/IX/V complex plays a very important role in hemostasis and thrombosis.[21][22]
- The GPIb/IX/V complex and von Willebrand factor (vWF) ensure normal primary hemostasis by initiating platelet adhesion at sites of vascular injury.[23]
- The GPIb/IX/V complex binds to von Willebrand factor (vWF) and that makes the initial contact adhesion of platelets to exposed vascular endothelium.[24]
- The GPIb/IX/V complex along with von Willebrand factor (vWF) also attach to ruptured plaque in damaged blood vessels.[25]
- And this attachment to ruptured plaque in damaged blood vessels is particularly seen at high shear flow rates (>800s-1).[26][27][28]
- In the formation of deep venous thrombosis GPIb/IX/V complex along with von Willebrand factor (vWF) plays a very critical role.[29][30][31][32][33][34]
- In an year, on an average 900 000 people in the United States suffer from deep vein thrombosis (DVT).
- GPIb-IX-V complex is multisubunit in nature consists of 4 subunits.
- Each of the 4 multisubunit is a member of the leucine-rich,which contains ~24 amino acid and are involved in such processes such as cell signaling, cell adhesion, and development.[35][36]
- In addition to its important role in binding to von Willebrand factor (VWF), this N-terminal domain of GPIbα is a pivotal binding site for multiple ligands mediating platelet interactions with matrix which are involved in thrombosis and inflammation.
- On activated platelets and endothelial cells other adhesive ligand include P-selectin, αMβ2 /CD11b/CD18.[37][38][39]
- The GPIb-IX-V complex plays very crucial role in coagulation especially in intrinsic pathway which has tendency to bind the receptors for thrombin, Factors XI and XII(having the shortest half life of all clotting factors), kininogen and at last to high molecular weight (HMW).[40][41]
- With the help of actin filaments ,Trp570, Phe568 and Trp570, GPIb-IX-V plays a crucial role in maintaining the platelets shape.[42]
- GPIb-IX-V/VWF adhesion was enhanced by NADPH(Nicotinamide adenine dinucleotide phosphate) oxidase, (p47 subunit), PI 3-kinase, Hic-5, TRAF4(TNF receptor-associated factor 4) Lyn, and Syk(Spleen tyrosine kinase) proteins.[43][44][45][46][47][48][49]
Causes
- Bernard-Soulier syndrome may be caused by abnormality in the genes for glycoprotein Ib/IX/V.[50][51][52][53][54]
- The genes for glycoprotein Ib/IX/V code for proteins that are usally found on the surface of platelets, the glycoprotein Ib/IX/V receptor.[55]
- Platelets do not adhere to damaged endothelium due to lack of receptors.
- Mutations are found in BP1b-alpha (MW 135 kDa), Gp1b-beta (MW 26 kDa) and GP9 (MW 20 kDa) but not on GP5(MW 82 kDa).[56][57]
Differentiating Bernard-Soulier syndrome from Other Disease
- Bernard-Soulier syndrome must be differentiated from[58][59] [60] [61][62][63] [64]
- Wiskott-Aldrich syndrome (small platelets)
- X-linked thrombocytopenia (small platelets)
- May-Hegglin syndrome(Giant platelets)
- Sebastian syndrome(Giant platelets)
- Fechtner syndrome(Giant platelets)
- Epstein syndrome(Giant platelets)
- Idiopathic thrombocytopenic purpura (ITP)- Most commonly misdiagnosed BSS as ITP.
Epidemiology and Demographics
- The prevalence of Bernard-Soulier syndrome is approximately 1 per 100,000 individuals worldwide.[65][66][67][68]
- Bernard-Soulier syndrome usually very rare that until now only ~100 cases have been reported.
- The severity of Bernard-Soulier syndrome increases with age.
- Bernard-Soulier syndrome commonly affects infants than younger and older people.
- Bernard-Soulier syndrome usually affects individuals of the Japan, Europe and North America.
- In Bernard-Soulier syndrome patients males and females are affected with equal frequency.
- The majority of Bernard-Soulier syndrome cases are reported in whites of European ancestry.
Risk Factors
- There are no established risk factors for Bernard-Soulier syndrome.
- Autosomal recessive genetic pattern was followed by Bernard-Soulier syndrome.
- Risk of Bernard-Soulier syndrome patients can be a carrier when they receive the following
- Risk of Bernard-Soulier syndrome in a child is 25% to 50% with each pregnancy when
- Two carrier parents to both pass the abnormal gene
Screening
- There is sufficient evidence to recommend routine screening for Bernard-Soulier syndrome with newer technologies in current clinical practice like the following.[69][70]
PFA-100(Platelet Function Analyzer)
- The most common screening test used for screening the patients with BSS [71][72][73][74]
- PFA-100 helps in differentiate between
- In other bleeding disorders like storage pool disorders PFA-100 is less sensitive.
Ultegra
- Ultegra an automated whole blood assay.
- Ultegra is very easy to use and can be done at the bedside.
- Ultegra helps in measuring platelet aggregation based on how strong activated platelets binding to fibrinogen.
Natural History, Complications, and Prognosis
- If left untreated, patients with Bernard-Soulier syndrome may progress to develop bleeding manifestations like mucocutaneous bleedings, prolonged bleeding.[75]
- Common complications of Bernard-Soulier syndrome include ante-, intra-, or postpartum hemorrhage in pregnant patients.[76]
- Prognosis is generally good in patients with Bernard-Soulier syndrome is but it is widely based on the severity of the condition.
Diagnosis
Diagnostic Study of Choice
- The initial laboratory test to be done is blood cell counts and blood smears.
- The diagnosis of Bernard-Soulier syndrome is based on the presence of a large platelets (diameter 4–10 μ m) with a rounded shape.
- One of the diagnoses of Bernard-Soulier syndrome is based on the bleeding time, which include
- Moderately bleeding time: 5–10 min
- Severe bleeding time: >20 min
- On blood smear manual counting is necessary as the large platelets is often mistaken by lymphocytes.
- Another unique diagnosing test for Bernard-Soulier syndrome is ristocetin-induced agglutination.
- Ristocetin is a drug that increases adherence between VWF and GP1b and is not seen in Bernard-Soulier syndrome.
- FVIII-von Willebrand factor levels are measured.
- Aggregation responses to thrombin is decreased.
- In Bernard-Soulier syndrome patients on testing we can observe the defect in prothrombin consumption and can help in the diagnosis.
- Defect in prothrombin consumption is due to effective binding of FXI due to a lack of GPIb and decrease in GPIb-fibrin-dependent thrombin.
- CD42 a-d a monoclonal antibody detected in flow cytometry also helps in the diagnosis and confirmation of the diagnosis in the patients with Bernard-Soulier syndrome.
- Genetic abnormalities testing also aid in the diagnosing the patients with Bernard-Soulier syndrome.
- Immunoblotting also helps in diagnosing Bernard-Soulier syndrome.
- Other new tests like platelet glycoprotein analysis by SDS-polyacrylamide gel separation are the news tests in the research which proves that in the diagnosis of the patients with the Bernard-Soulier syndrome.
