Extractions: Factor V Leiden is een aangeboren en erfelijke bloedstollingziekte. Door Factor V Leiden blijft het bloed stollen. De factor V in het bloed is afwijkend. Daardoor kan het APC niet functioneren. APC betekent: geactiveerd Proteïne C. Het APC heeft een taak bij het stoppen van de bloedstolling. Als iemand een wondje heeft komt daar door bloedstolling een korstje op. Eerst vormt zich een voorlopig afdeklaagje. Aan dit afdeklaagje hechten zich stoffen, onder andere factor V. Factor V heeft de functie de bloedstolling te stoppen zodra het korstje stevig genoeg is. Maar bij ongevoeligheid voor APC (APC resistentie) reageert Factor V te langzaam op de werking van APC. Daardoor wordt het bloed te stolbaar. Stolseltjes kunnen vervolgens aangroeien en ergens in het lichaam een verstopping in de bloedbaan veroorzaken. Dit leidt tot trombose. Trombose komt vaak voor in de bloedvaten van de benen. Trombose kan ook op andere plaatsen in het lichaam voorkomen. Als het in de longen optreedt is er sprake van longembolie. Sommige situaties verhogen de kans dat Factor V Leiden opspeelt. Zoals het gebruik van de anticonceptiepil, zwangerschap, roken of te weinig bewegen.

De mate waarin Factor V Leiden invloed op je leven heeft, kan sterk verschillen. Sommigen merken er niets van, anderen worden er dagelijks mee geconfronteerd. Om klachten tot een minimum te beperken hebben wij een paar tips voor je bij elkaar gezet. Direct hieronder tref je algemene tips aan. Bovenaan kies je uit specifieke onderwerpen, maar kijk ook eens bij: Algemene tips: Meldt bij iedere arts dat je Factor V Leiden hebt en of je anti-stollingsmedicijnen gebruikt. Dit is namelijk belangrijk als je geopereerd moet worden. Ook is het nodig je tandarts op de hoogte te brengen van het gebruik van anti-stollingsmedicijnen. Bij het trekken van kiezen of tanden kan hij dan in overleg met de trombosedienst je medicatie tijdelijk laten aanpassen. Draag een medische kaart of SOS Ketting bij je waarin je medicatie staat vermeld. Zorg ervoor dat je bloed goed kan circuleren. Knellende kleding of een houding waarbij je de bloedcirculatie belemmert, moet je vermijden. Denk bijvoorbeeld ook:

Factor V Leiden Syndrome
factor v leiden Thrombophilia is the most common inherited disorder of blood clotting.
http://ibis-birthdefects.org/start/f5fact.htm

Extractions: Report Broken Links Exchange Banners Contact Us Factor V Leiden Syndrome See I.B.I.S in English Spanish Russian Ukranian Search Factor V Leiden Syndrome Abstract Factor V Leiden Thrombophilia is the most common inherited disorder of blood clotting. It is the result of a specific mutation in the gene for factor V which leads to increased risk for clots in the large veins of the legs (deep venous thrombosis), or clots that travel though the bloodstream and embed in the lungs (pulmonary embolism). It is inherited in an autosomal dominant manner. If a person inherits one copy of the mutated gene, he or she has a 2 to 8 times risk (2 to 8 in 1,000) for developing clots. If a person inherits two copies of the factor V Leiden mutation, the risk increases up to 80 times (80 in 1,000). It is estimated that three to eight per cent of the Caucasian population and 1.2 percent of the African-American population in the U.S. carry one copy of the gene and about 1 in 1000 Caucasians have two copies of the gene. Testing: DNA analysis of the Factor V gene.

Extractions: A simple functional Screening Test for Factor V (Leiden) Factor V Leiden and APC resistance The Factor V (Leiden) mutation has been identified as the most important underlying cause of hereditary thrombophilia. This mutation in clotting factor V confers resistance to normal proteolytic cleavage by activated protein C (APC), resulting in impaired function of an important regulatory mechanism in the clotting process. Factor V Leiden has traditionally been first detected by screening tests using addition of exogenous APC to patient plasma in an APTT test, where the clotting time for normal patients is prolonged, while individuals with a mutation in Factor V exhibit shorter clotting time results. However the mutation can also be detected by a Dilute-Russell's Viper Venom Time (DRVVT) based test. The DRVVT method avoids limitations inherent in the APTT based method, which requires a normal baseline APTT and may be affected by high concentrations of Factor VIII, Lupus Anticoagulant and anticoagulant therapy. The use of a DRVVT test also eliminates the requirement to pre-dilute patient samples with Factor V deficient plasma. GradiLeiden V GradiLeiden V is a simple alternative to the APTT based procedure for detecting resistance to Activated Protein C caused by the Factor V (Leiden) defect. This system is based on the activation of the patients endogenous Protein C by pre-incubation with Agkistodon contortrix venom reagent (VACL). A Phospholipid Rich Russell's Viper Venom reagent (PR3V) is then used to perform a Dilute Russell's Viper Venom Time (DRVVT) test on the plasma

Activated Protein C Resistance and the Factor V Leiden Mutation [CO004550] Related Information Synonyms Activated Protein C Resistance; APC; Protein C Resistance, Activated Abstract Resistance to activated protein C (APC) is a condition which leads to a hypercoagulable state with an increased risk for venous thrombosis. The effect of exogenous APC on patient's clotting time [usually activated partial thromboplastin time (PTT)] is used to detect presence of resistance to APC (as occurs in individuals with the factor V Leiden mutation). A few laboratories might use clotting times other than the PTT. DNA-based assays can be used to directly detect the presence of the factor V Leiden mutation.

Factor V Leiden [CO006300] Related Information Abstract See Activated Protein C Resistance and Factor V Leiden Mutation . The term "factor V Leiden" is often used interchangeably with activated protein C resistance, although they are not true synonyms. The factor V Leiden mutation causes the vast majority of cases of activated protein C resistance. Whether or not additional mutations other than factor V Leiden can cause clinically-significant activated protein C resistance is under continued investigation.

Extractions: When I was 19 years old, I developed my first venous thrombosis. I had been on oral contraceptives for about three months at the time and they felt this was the cause of my first deep vein thrombosis (DVT). Three years later, following the birth of my second child, I developed my second DVT, I was 22 years old. Of course this was assumed to be related to childbirth. Both DVTs had been in my left calf, so I wore my support stocking and tried to elevate my legs as much as possible. Although that leg was never quite the same again. Three years after my second child was born I was in my first year of college. My son was in the second grade and was going to have some time off, so my mother met us at school to take him home with her for a few days. She looked great, happy and full of her usual energy. We had coffee and talked for awhile, then I went to class. I never saw her alive again. She died very suddenly that night. Dad thought she was having a nightmare, he tried to awake her, but she was gone. They had to take her out of the home with my little son there. She was 46 years old, it was ten days before her 47th birthday. We never found out why she died, although it always haunted me. I wanted to live longer than my mom. Two years ago I lost my big brother Mike, this was very sudden also and just as shocking for us. He was 47 years old. Six months older than mom was. He died of a sudden heart attack.

Extractions: Thromboses are caused by disorders of the coagulation system. One later complication can be the development of a lung emboly. One of the regulating factors of the coagulation system is Activated Protein C (APC), which is a serin protease influencing the coagulation process together with a cofactor by proteolytic inactivation of Factor Va and VIIIa, two components of the coagulation cascade. Factor Va is derived from the Factor V-Protein by cleavage, which in turn is mediated by Factor IIa. According to current knowledge, the resistance against Activated Protein C (APC) is the most common genetic risk factor for venose coagulation disorders. The cause is a point mutation in the Factor V-gene bringing about a substitution of guanin (G) by adenin (A) at position 1691. In the translated protein this results in the substitution of the amino acid arginin by glutamin at the position 506 (FV:Q ). The altered Factor V gene product is called Factor V Leiden (FVL).
