Skłonność do zakrzepicy
Leczenie
Trombofilia to stan predysponujący do nadmiernej aktywacji układu krzepnięcia i powstawania zakrzepów, który może mieć charakter wrodzony lub nabyty. Leczenie przeciwzakrzepowe jest wskazane przede wszystkim po epizodach zakrzepicy żylnej lub tętniczej, u pacjentów z wysokim ryzykiem nawrotów oraz w sytuacjach przejściowego zwiększenia ryzyka (np. ciąża, zabiegi operacyjne, unieruchomienie). Farmakoterapia opiera się na antykoagulantach, takich jak heparyna drobnocząsteczkowa (LMWH), warfaryna (monitorowana wskaźnikiem INR w zakresie 2,0-3,0), nowe doustne antykoagulanty (NOAC/DOAC) oraz fondaparinuks. W ciąży preferowana jest LMWH, natomiast warfaryna i DOAC są przeciwwskazane. Czas leczenia zależy od etiologii i przebiegu zakrzepicy: od 3-6 miesięcy po epizodzie wywołanym czynnikiem przejściowym do leczenia długoterminowego lub bezterminowego w przypadku nawrotów lub wysokiego ryzyka, zwłaszcza u pacjentów z homozygotycznymi mutacjami czynnika V Leiden, protrombiny G20210A lub niedoborem antytrombiny.
Leczenie skłonności do zakrzepicy
Skłonność do zakrzepicy (trombofilia) to stan zwiększonej tendencji do tworzenia zakrzepów krwi. Leczenie trombofilli zależy od wielu czynników, w tym typu trombofilli (wrodzona lub nabyta), obecności czynników ryzyka, historii epizodów zakrzepowych oraz specyficznych okoliczności, takich jak ciąża. Warto podkreślić, że nie wszystkie osoby z trombofilią wymagają leczenia – około 90% osób z trombofilią nigdy nie doświadcza zakrzepicy.12
Wskazania do leczenia
Leczenie trombofilli jest zazwyczaj podejmowane w następujących sytuacjach:345:
- Po wystąpieniu epizodu zakrzepicy żylnej lub tętniczej
- U osób z wysokim ryzykiem rozwoju zakrzepicy
- W sytuacjach tymczasowego podwyższonego ryzyka zakrzepicy (np. zabieg operacyjny, ciąża, unieruchomienie)
- U pacjentów z nawracającymi epizodami zakrzepicy
Warto podkreślić, że samo stwierdzenie trombofilli bez wystąpienia epizodu zakrzepowego zwykle nie jest wskazaniem do długoterminowego leczenia przeciwkrzepliwego.89 Decyzja o leczeniu powinna być zawsze podejmowana indywidualnie, po dokładnej ocenie stosunku korzyści do ryzyka (głównie ryzyka krwawienia).10
Leki przeciwkrzepliwe
Podstawą leczenia trombofilli jest farmakoterapia lekami przeciwkrzepliwymi (antykoagulantami). Najczęściej stosowane leki to:111213
- Heparyna – stosowana w początkowej fazie leczenia, działa szybko, bezpieczna w ciąży. Najczęściej stosowana jest heparyna drobnocząsteczkowa (LMWH) podawana podskórnie.
- Warfaryna (Coumadin, Jantoven) – lek doustny, wymaga regularnego monitorowania czasu protrombinowego i wskaźnika INR.
- Nowe doustne antykoagulanty (NOAC/DOAC) – takie jak riwaroksaban (Xarelto), apiksaban (Eliquis), dabigatran (Pradaxa) – nie wymagają regularnego monitorowania, lecz są przeciwwskazane w ciąży.
- Fondaparinuks – syntetyczny inhibitor czynnika Xa stosowany w leczeniu i profilaktyce zakrzepicy.
- Kwas acetylosalicylowy (aspiryna) w małych dawkach – stosowany głównie w przypadku zespołu lepkiej płytki (SPS) i niektórych postaci trombofilli, szczególnie w ciąży.1415
Wybór odpowiedniego leku przeciwkrzepliwego zależy od wielu czynników, w tym rodzaju trombofilli, wieku pacjenta, funkcji nerek i wątroby, interakcji z innymi lekami oraz preferencji pacjenta.1617 Istotne jest też ustalenie optymalnej dawki leku, by uzyskać równowagę między skutecznością przeciwzakrzepową a ryzykiem krwawienia.18
Czas trwania leczenia
Czas leczenia przeciwkrzepliwego zależy od rodzaju trombofilli, rodzaju epizodu zakrzepowego (wywołany czynnikiem przejściowym czy samoistny) oraz indywidualnego ryzyka nawrotu zakrzepicy.1920 Ogólne zasady dotyczące czasu leczenia:
- Pierwszy epizod zakrzepicy wywołanej przemijającym czynnikiem ryzyka (np. zabieg operacyjny) – leczenie przez 3-6 miesięcy
- Pierwszy epizod samoistnej zakrzepicy – leczenie przez minimum 3-6 miesięcy, a w przypadku wysokiego ryzyka nawrotu – rozważenie leczenia bezterminowego
- Nawracające epizody zakrzepicy – zazwyczaj leczenie długoterminowe lub bezterminowe
- Zakrzepica zagrażająca życiu (np. zatorowość płucna) – rozważenie długoterminowego leczenia
Pacjenci z homozygotyczną postacią mutacji czynnika V Leiden, homozygotyczną postacią mutacji protrombiny G20210A, złożoną heterozygotycznością dla obu tych mutacji, a także pacjenci z niedoborem antytrombiny zwykle wymagają dłuższego leczenia ze względu na wyższe ryzyko nawrotu zakrzepicy.24
Leczenie trombofilli w ciąży
Ciąża stanowi szczególne wyzwanie w leczeniu trombofilli ze względu na fizjologiczny stan nadkrzepliwości oraz konieczność unikania leków potencjalnie szkodliwych dla płodu.2526 W przypadku kobiet ciężarnych z trombofilią:
- Preferowanym lekiem jest heparyna drobnocząsteczkowa, która nie przechodzi przez łożysko
- Warfaryna jest przeciwwskazana, szczególnie w pierwszym trymestrze ciąży ze względu na potencjalne działanie teratogenne
- Nowe doustne antykoagulanty (DOAC) są przeciwwskazane w ciąży
- W niektórych przypadkach stosuje się małe dawki kwasu acetylosalicylowego (75-100 mg) w połączeniu z heparyną drobnocząsteczkową
- Leczenie przeciwkrzepliwe zwykle kontynuuje się przez 6-12 tygodni po porodzie (okres podwyższonego ryzyka zakrzepicy)
Decyzja o profilaktyce przeciwzakrzepowej w ciąży powinna uwzględniać typ trombofilli, historię zakrzepicy u pacjentki oraz wywiad rodzinny.3031
Profilaktyka przeciwzakrzepowa
Profilaktyka przeciwzakrzepowa u osób z trombofilią jest wskazana w sytuacjach podwyższonego ryzyka zakrzepicy:3233
- Przed planowanym zabiegiem operacyjnym
- W trakcie unieruchomienia (np. długotrwałe loty, unieruchomienie kończyny)
- W ciąży i połogu (szczególnie u kobiet z wysokim ryzykiem)
- W trakcie hospitalizacji z powodu ostrej choroby
Profilaktyka może obejmować stosowanie heparyny drobnocząsteczkowej, stopniowanych pończoch uciskowych lub przerywanej kompresji pneumatycznej.3435
Metody niefarmakologiczne
Oprócz farmakoterapii, w leczeniu i profilaktyce trombofilli istotną rolę odgrywają metody niefarmakologiczne:3637
- Pończochy uciskowe – zmniejszają ryzyko zakrzepicy żył głębokich, szczególnie po przebytej zakrzepicy
- Aktywność fizyczna – regularny ruch poprawia przepływ krwi i zmniejsza ryzyko zakrzepicy
- Utrzymanie prawidłowej masy ciała – otyłość zwiększa ryzyko zakrzepicy
- Unikanie długotrwałego unieruchomienia – podczas długich podróży zaleca się okresową aktywność fizyczną
- Odpowiednie nawodnienie – zapobiega zagęszczeniu krwi
W przypadku kobiet z trombofilią należy rozważyć unikanie estrogenowej antykoncepcji hormonalnej i hormonalnej terapii zastępczej, które zwiększają ryzyko zakrzepicy.3839
Leczenie specyficznych typów trombofilli
Niektóre typy trombofilli wymagają specyficznego podejścia terapeutycznego:404142
- Zespół antyfosfolipidowy – zwykle wymaga długotrwałego leczenia przeciwkrzepliwego, często z docelowym wyższym INR (2,5-3,5) w przypadku stosowania warfaryny
- Niedobór antytrombiny – może wymagać suplementacji koncentratem antytrombiny w sytuacjach wysokiego ryzyka zakrzepowego
- Niedobór białka C lub S – szczególne ryzyko martwicy skóry indukowanej warfaryną; rozpoczęcie leczenia warfaryną powinno być poprzedzone terapią heparyną
- Zespół lepkiej płytki (SPS) – leczenie opiera się głównie na lekach przeciwpłytkowych (kwas acetylosalicylowy)
Monitorowanie leczenia
Prawidłowe monitorowanie leczenia przeciwkrzepliwego jest kluczowe dla jego skuteczności i bezpieczeństwa.4344 Monitorowanie obejmuje:
- Regularne badania laboratoryjne – w przypadku warfaryny monitorowanie wskaźnika INR (docelowy zakres zwykle 2,0-3,0)
- Ocenę skuteczności leczenia – ustąpienie objawów, brak nowych epizodów zakrzepowych
- Monitorowanie działań niepożądanych – głównie krwawień
- Ocenę przestrzegania zaleceń przez pacjenta
- Okresową ponowną ocenę stosunku korzyści do ryzyka związanego z kontynuacją leczenia
Pacjenci stosujący warfarynę powinni regularnie kontrolować wskaźnik INR, podczas gdy pacjenci przyjmujący DOAC wymagają okresowej oceny funkcji nerek i wątroby.45
Trombofilia a badania diagnostyczne
Warto zwrócić uwagę na zagadnienie badań diagnostycznych w kierunku trombofilli, które ściśle wiąże się z decyzjami terapeutycznymi. Współczesne wytyczne sugerują selektywne podejście do badań w kierunku trombofilli:464748
- Nie zaleca się rutynowych badań w kierunku trombofilli u wszystkich pacjentów z zakrzepicą żylną
- Badania mają sens tylko wtedy, gdy ich wynik wpłynie na decyzje terapeutyczne
- Nie należy wykonywać badań w ostrej fazie zakrzepicy ani w trakcie pierwszych 3 miesięcy leczenia przeciwkrzepliwego (ryzyko fałszywych wyników)
- Badania mogą być wskazane u pacjentów z nieprowokowaną zakrzepicą, u których rozważa się zaprzestanie leczenia przeciwkrzepliwego
- Rozważenie badań u pacjentów z zakrzepicą w młodym wieku, zakrzepicą o nietypowej lokalizacji lub z dodatnim wywiadem rodzinnym
Ważnym aspektem jest fakt, że badanie w kierunku trombofilli ma ograniczoną wartość w prognozowaniu ryzyka nawrotu zakrzepicy i często nie wpływa na długość leczenia przeciwkrzepliwego.5354
Podsumowanie
Leczenie trombofilli powinno być zindywidualizowane i oparte na dokładnej ocenie ryzyka zarówno zakrzepicy, jak i krwawienia. Niezbędna jest współpraca między specjalistami różnych dziedzin (hematologia, kardiologia, położnictwo) w celu zapewnienia optymalnej opieki.5556 Leczenie przeciwkrzepliwe pozostaje podstawą terapii u pacjentów z trombofilią, którzy doświadczyli zakrzepicy lub są w grupie wysokiego ryzyka jej wystąpienia.57
Warto podkreślić, że u znacznej większości osób z trombofilią nigdy nie dochodzi do zakrzepicy, dlatego rutynowe leczenie przeciwkrzepliwe bez objawów zakrzepowych nie jest zalecane.58 Celem leczenia jest zarówno zapobieganie nowym epizodom zakrzepowym, jak i ograniczenie długoterminowych powikłań zakrzepicy, takich jak zespół pozakrzepowy lub nadciśnienie płucne.5960

- #1 Thrombophilia: Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/21797-thrombophilia
Thrombophilia treatment for acquired or inherited types of the condition may include compression stockings for your legs or medicine to prevent or break up a blood clot. Some people may need surgery to remove a blood clot. […] Providers order medications, such as: Blood thinners (anticoagulants) like heparin, warfarin (Coumadin or Jantoven) or newer blood thinners like rivaroxaban or apixaban. […] Although you cant cure the kind of thrombophilia that you inherit, you can treat it. […] Its important to know that blood thinners dont dissolve blood clots. They stabilize the blood clots so they dont move or get bigger, and allow your bodys natural resources to absorb the clot over time. […] If youre at a high risk of blood clots, your provider may give you: Heparin after surgery if youre at risk for a venous thromboembolism (VTE). […] Nearly 90% of people who have thrombophilia never get a blood clot, but some people get one or more serious clots. […] You may need to take blood thinners if your risk of forming more blood clots is high.
- #2 Thrombophiliahttps://www.nhs.uk/conditions/thrombophilia/
There is currently no cure for thrombophilia that’s caused by altered genes you inherit from your parents (inherited thrombophilia). […] Thrombophilia that starts later in life (acquired thrombophilia) can sometimes get better if the underlying cause is treated. […] If you need treatment, you’ll usually be offered anticoagulant medicine. It works by making your blood less sticky so it’s less likely to clot.
- #3 Thrombophilia: Causes, Symptoms, and Treatmenthttps://patient.info/allergies-blood-immune/blood-clotting-tests/thrombophilia
What is the treatment for thrombophilia? […] The first step is for you and your doctor to consider how much risk there is of you developing a blood clot. […] Possible treatments for thrombophilia are: […] Low-dose aspirin inhibits the action of platelets, so can help to prevent blood clots. […] Anticoagulation is often called 'thinning’ of the blood. […] Anticoagulant medication is commonly used to treat a venous thrombosis (such as a DVT) or a pulmonary embolism. […] In thrombophilia, anticoagulant medication may be advised if: […] You have had a blood clot, to prevent another one. […] You have not had a blood clot but have a high risk of developing one. […] You have a temporary situation that puts you at high risk of a blood clot. […] Warfarin is the usual anticoagulant.
- #4 Thrombophilia: Causes, Symptoms, and Treatmenthttps://patient.info/allergies-blood-immune/blood-clotting-tests/thrombophilia
The aim is to get the dose of warfarin just right so the blood will not clot easily. […] An INR of 2.5 is usually the aim if you take warfarin to prevent a blood clot in thrombophilia or to treat a DVT or pulmonary embolism. […] Heparin is an injectable anticoagulant. […] If you are pregnant or planning a pregnancy, discuss this with your doctor, and tell your midwife and doctor specialising in pregnancy and childbirth (obstetrician) about the thrombophilia. […] Treatment for thrombophilia may be different in pregnancy because: […] Some women with certain types of thrombophilia are advised to take low-dose aspirin while pregnant, to help prevent miscarriage or pregnancy problems. […] The pregnancy itself increases the risk of a venous thrombosis – this applies to the whole pregnancy and especially to the six weeks after childbirth.

1. Treatment modalities and outcomes of acute VTE in patients with thrombophilia are the same as in patients with other forms of venous thrombosis. In patients with severe deficiency of natural anticoagulants, additional options (substitution) should be considered. The presence of a thrombophilia may influence the duration of treatment. […] 2. In patients who would otherwise be discontinuing anticoagulants, lifelong secondary antithrombotic prevention with a VKA or DOAC could be considered after the first episode of VTE in patients with AT deficiency, homozygotes for factor V Leiden, or patients with the 20210A variant of the prothrombin gene, as well as patients with coexisting heterozygosity for these conditions, or in patients with antiphospholipid syndrome with an unprovoked VTE event. After the first episode of unprovoked thrombosis in patients with types of thrombilia other than those mentioned above, anticoagulant treatment should be continued for 3 months. Consideration for extended-duration therapy in such patients (particularly men) is reasonable if the risk of bleeding is low to moderate. […] 3. Patients with suspected TTS should have diagnostic testing performed before treatment with high-dose IV immunoglobulins and nonheparin anticoagulants is initiated, but likely without waiting for results.
- #6 Thrombophilia: Inherited, Symptoms, Screen Test, Treatment, Causehttps://www.healthline.com/health/thrombophilia
You may not need treatment at all unless you develop a blood clot or are at high risk of developing one. Some factors that can influence treatment decisions are: […] Medications may include anticoagulants such as warfarin or heparin. Warfarin (Coumadin or Jantoven) is an oral drug, but it takes a few days to start working. If you have a clot that needs immediate treatment, heparin is a fast-acting injectable drug that can be used with the warfarin. […] If you have thrombophilia, or if you’re taking anticlotting medications, be sure to inform all healthcare professionals before having medical procedures. […] In some cases, your doctor may recommend long-term use of blood thinners, which will require periodic blood testing. […] Thrombophilia can be successfully managed.
- #7 Blood Clotting Disorders: Types, Signs and Treatmenthttps://my.clevelandclinic.org/health/diseases/16788-blood-clotting-disorders-hypercoagulable-states
A blood clotting disorder makes your blood form clots too easily. This is also called a hypercoagulable state or thrombophilia. […] In most cases, you only need blood clotting disorder treatment when a blood clot develops in a vein or artery. Anticoagulants decrease your blood’s ability to clot and prevent additional clots from forming. […] Anticoagulant medications include: Aspirin, Warfarin (Coumadin or Jantoven), Heparin, Low-molecular weight heparin, Fondaparinux, Direct oral anticoagulants (tablets) such as rivaroxaban, apixaban or dabigatran. […] Your healthcare provider will talk to you about the benefits and risks of these medications. This information, along with your diagnosis, will help determine the type of anticoagulant medication you will take, how long you will need to take it, and the type of follow-up monitoring you need.
- #8 What Is Thrombophilia?https://www.webmd.com/dvt/thrombophilia-overview
There is no treatment for thrombophilia until you get a blood clot. What happens then depends on where the clot is, its size, and other things. […] If you have the antiphospholipid antibody syndrome form of thrombophilia, you may need long-term treatment with blood thinners. […] If you’re a woman, you may need to avoid certain forms of hormonal birth control that have estrogen. You could take progestin-only pills instead. Your doctor also may recommend staying away from hormone replacement therapy for menopause symptoms. […] If you have thrombophilia, you can lower your chances of having unwanted blood clots with lifestyle changes, including: Exercise, Keeping a healthy weight, Limiting salt, saturated fats, and cholesterol, Avoiding long periods of not moving.
- #9 Thrombophilia | nidirecthttps://www.nidirect.gov.uk/conditions/thrombophilia
Many people with thrombophilia won’t need treatment. You’ll only need treatment if you develop a blood clot or you’re at risk of developing a clot. […] If you have been diagnosed with thrombophilia, the healthcare professional managing your care will discuss with you the most appropriate treatment options.
- #10 Thrombophilia: Causes, Symptoms, and Treatmenthttps://patient.info/allergies-blood-immune/blood-clotting-tests/thrombophilia
Certain situations can temporarily put you at high risk of having a blood clot, and in these situations you may be advised to take extra treatment for a while. […] If you are having any medical treatment or surgery, tell your doctor/nurse/pharmacist about the thrombophilia. […] It is therefore important to be aware of the symptoms and seek treatment immediately if you suspect any kind of blood clot. […] Many forms of thrombophilia are mild, so that the outlook (prognosis) for many people with thrombophilia means that they have no problems from their condition. […] Treatment with anticoagulant medication has to be carefully assessed, as its use also has certain risks, such as bleeding.

- #12 Thrombophilia | Clotting Disorders | UC Davis Hemostasis and Thrombosis Centerhttps://health.ucdavis.edu/hemophilia/clotting-disorders/thrombophilia.html
Thrombophilia is a condition in which there’s an imbalance in naturally occurring blood-clotting proteins, or clotting factors. This can put people at risk of developing blood clots. […] Treatment may not be needed at all unless a blood clot develops, or if an individual is at high risk of developing one. […] Medications may include anticoagulants such as warfarin or heparin. Warfarin (Coumadin or Jantoven) is an oral drug, but it takes a few days to start working. In the case of a clot that needs immediate treatment, heparin is a fast-acting injectable drug that can be used with the warfarin. […] Regular blood testing needs to be done to make sure that the right amount of warfarin is being taken. Blood tests include the prothrombin time test and International Normalized Ratio (INR).

- #14 Primary thrombophilia XV: antithrombotic treatment of sticky platelet syndrome worldwide – GarcÃa-Navarrete – Annals of Bloodhttps://aob.amegroups.org/article/view/5039/html
Sticky platelet syndrome (SPS) is a common but under-recognized cause of thrombosis. Treatment with antiplatelet drugs results in a low re-thrombosis rate. […] Most patients with SPS are treated with antiplatelet drugs worldwide, the re-thrombosis rate is very low. Physicians worldwide are aware of the fact that the best treatment for persons with the SPS is the use of antiplatelet drugs. […] Treatment of SPS relies on diminishing the inherent platelet hyperaggregability by means of anti-platelet drugs; in most cases, aspirin appears adequate but there are situations in which other anti-platelet drugs must be employed. […] By using antiplatelet drugs, mainly aspirin, the platelet hyperreactivity of patients can be reverted and that this translates into a low re-thrombosis rate. […] The re-thrombosis rate for patients given antiplatelet drugs was 5/332 (1.5%) and only 3 patients died.
- #15 Primary thrombophilia XV: antithrombotic treatment of sticky platelet syndrome worldwide – GarcÃa-Navarrete – Annals of Bloodhttps://aob.amegroups.org/article/view/5039/html
The re-thrombosis rate that we found in our previous prospective study (3.6%), contrasts with that observed in the whole group of patients which we are presenting here (1.5%); this may stem from the fact that the data collection period in our group is substantially longer. […] For patients with history of thrombosis and the SPS phenotype, in a prospective study, we found that the platelet hyperaggregability can be reverted by means of aspirin in most cases (75%), whereas other/additional antiplatelet drugs were needed in the remaining 25%. […] In summary, we have found that physicians worldwide are aware of the fact that the best treatment for persons with the SPS is the use of antiplatelet drugs. The rethrombosis rate is very low.

- #18 Thrombophilia – Blood Clotshttps://www.stoptheclot.org/about-clots/thrombophilia/thrombophilia/
People with HAD are often treated by getting extra antithrombin to compensate for the antithrombin that is missing from the body. Treatment is more common in certain high-risk situations such as surgery, pregnancy and childbirth, or when the person already has a blood clot. […] Blood clots are managed with anticoagulants, also known as blood thinners. […] The goal will be to maximize treatment benefits while minimizing adverse effects.
- #19 Inherited and Secondary Thrombophilia: Clinician Updatehttps://pmc.ncbi.nlm.nih.gov/articles/PMC3979345/
Thrombophilia is defined as a predisposition (susceptibility) to thrombosis. […] Most persons with a thrombophilia do not develop thrombosis. Thus, thrombophilia must be considered in the context of other risk factors for incident thrombosis, or predictors of recurrent thrombosis, when estimating the need for primary or secondary prophylaxis, respectively. […] In general, patients with an inherited or acquired thrombophilia and a first-lifetime venous thromboembolism should be managed in standard fashion with intravenous unfractionated heparin, low-molecular-weight heparin (LMWH), fondaparinux, or rivaroxaban. […] Secondary prophylaxis may be recommended after completion of acute treatment for patients at high risk for VTE recurrence and acceptable risk for a bleeding complication. […] Secondary prophylaxis may be recommended for idiopathic, recurrent, or life-threatening venous thromboembolism (e.g., pulmonary embolism, especially in association with persistently reduced cardiopulmonary functional reserve due to chronic cardiopulmonary disease; phlegmasia with threatened venous gangrene; or purpura fulminans), persistent clinical risk factors (e.g., active cancer, chronic neurological disease with leg paresis, or other persistent secondary causes of thrombophilia), a persistent lupus anticoagulant and/or high-titer anticardiolipin or anti-beta2 glycoprotein-1 antibody, antithrombin, protein C or protein S deficiency, increased basal factor VIII activity or hyperhomocysteinemia, combined heterozygous carriers for more than one familial thrombophilia (e.g., heterozygous for the factor V Leiden and prothrombin G20210A mutations, etc.), or homozygous carriers, a persistently increased plasma fibrin D-dimer, and possibly residual vein thrombosis.
- #20 Inherited and Secondary Thrombophilia: Clinician Updatehttps://pmc.ncbi.nlm.nih.gov/articles/PMC3979345/
The risk of recurrence among isolated heterozygous carriers for either the factor V Leiden or prothrombin G20201A mutations is relatively low and insufficient to warrant secondary prophylaxis. […] The risk of venous thromboembolism recurrence decreases with time following the incident event, and the risk of anticoagulant-related bleeding also may vary over time. Consequently, the benefits and risks of secondary prophylaxis must be continually re-evaluated. […] Special coagulation testing for an inherited or acquired thrombophilia showed reduced plasma antithrombin activity and antigen. […] Secondary prophylaxis was recommended after acute treatment was completed. […] Hyperhomocysteinemia is a weak risk factor for incident and recurrent VTE. […] For both of these cases, thrombophilia testing identified treatable and acquired important risk factors for VTE and guided recommendations for secondary prophylaxis.

- #22 Recurrent Venous Thromboembolism | AAFPhttps://www.aafp.org/pubs/afp/issues/2022/0400/p377.html
Venous thromboembolism (VTE) recurrence rates are three times higher in patients with chronic or no risk factors compared with those who have transient risk factors after stopping anticoagulation therapy. […] Thrombophilia evaluation should be considered only in selected patients because routine evaluation has not been shown to improve outcomes. […] Patients with VTE should receive three months of anticoagulation therapy. […] There is growing evidence regarding the use of risk assessment models to determine risk of recurrence, but this has not been incorporated into guidelines. […] Do not routinely test for thrombophilia in patients with provoked VTE. Routine testing in patients with unprovoked VTE is discouraged. […] Patients with VTE due to chronic risk factors or with no identifiable risk factors (unprovoked) should continue anticoagulation indefinitely unless they are at high risk of bleeding.

Thrombophilia treatment and management […] The use of short- or long-term anticoagulation should be considered, weighing up the reduction of VTE risk against the risk of serious haemorrhage. This depends on the individual diagnosis and any other medical conditions. Guidelines suggest that, as a general rule: […] All patients with known thrombophilia or previous VTE – consider short-term thromboprophylaxis at times of increased VTE risk. […] Patients with 2 spontaneous VTEs – consider indefinite anticoagulation. […] Patients with recurrent VTEs linked to a provoking factor (eg, surgery, pregnancy, oestrogen use) may not require long-term anticoagulation but do require prophylaxis during any further high-risk situations. […] Asymptomatic family members found to have a thrombophilic genotype – the risk of long-term anticoagulation outweighs the benefits. Consider short-term prophylaxis to cover periods of high VTE risk.

1. Treatment modalities and outcomes of acute VTE in patients with thrombophilia are the same as in patients with other forms of venous thrombosis. In patients with severe deficiency of natural anticoagulants, additional options (substitution) should be considered. The presence of a thrombophilia may influence the duration of treatment. […] 2. In patients who would otherwise be discontinuing anticoagulants, lifelong secondary antithrombotic prevention with a VKA or DOAC could be considered after the first episode of VTE in patients with AT deficiency, homozygotes for factor V Leiden, or patients with the 20210A variant of the prothrombin gene, as well as patients with coexisting heterozygosity for these conditions, or in patients with antiphospholipid syndrome with an unprovoked VTE event. After the first episode of unprovoked thrombosis in patients with types of thrombilia other than those mentioned above, anticoagulant treatment should be continued for 3 months. Consideration for extended-duration therapy in such patients (particularly men) is reasonable if the risk of bleeding is low to moderate. […] 3. Patients with suspected TTS should have diagnostic testing performed before treatment with high-dose IV immunoglobulins and nonheparin anticoagulants is initiated, but likely without waiting for results.

The decision to provide thromboprophylaxis to pregnant patients depends on the following: […] These factors affect the decision to provide prophylaxis, as well as the timing (antenatal or postpartum only) and intensity of therapy. Early recognition of risk factors and wide implementation of thromboprophylaxis guidelines in the UK found a significant decrease in their maternal mortality due to thromboembolisms. […] A systematic review by Croles et al reported that antepartum or postpartum thrombosis prophylaxis, or both should be considered for women with antithrombin, protein C, or protein S deficiency or with homozygous factor V Leiden. […] For patients who meet the criteria for obstetric antiphospholipid syndrome, the American College of Rheumatology (ACR) strongly recommends combined lowdose aspirin and prophylacticdose heparin (usually LMWH).

[…] Because data on the maternal and fetal safety of direct oral anticoagulants (DOACs) are scant, these agents are generally avoided in pregnancy.
- #29 Thrombophilia – Wikipediahttps://en.wikipedia.org/wiki/Thrombophilia
There is no specific treatment for most thrombophilias, but recurrent episodes of thrombosis may be an indication for long-term preventive anticoagulation. […] In those with unprovoked and/or recurrent thrombosis, or those with a high-risk form of thrombophilia, the most important decision is whether to use anticoagulation medications, such as warfarin, on a long-term basis to reduce the risk of further episodes. […] Those with antiphospholipid syndrome may be offered long-term anticoagulation after a first unprovoked episode of thrombosis. […] Women with a thrombophilia who are contemplating pregnancy or are pregnant usually require alternatives to warfarin during pregnancy, especially in the first 13 weeks, when it may produce abnormalities in the unborn child. Low molecular weight heparin (LMWH, such as enoxaparin) is generally used as an alternative. […] When women experience recurrent pregnancy loss secondary to thrombophilia, some studies have suggested that low molecular weight heparin reduces the risk of miscarriage.

Sticky platelet syndrome (SPS) is a common but under-recognized cause of thrombosis. Treatment with antiplatelet drugs results in a low re-thrombosis rate. […] Most patients with SPS are treated with antiplatelet drugs worldwide, the re-thrombosis rate is very low. Physicians worldwide are aware of the fact that the best treatment for persons with the SPS is the use of antiplatelet drugs. […] Treatment of SPS relies on diminishing the inherent platelet hyperaggregability by means of anti-platelet drugs; in most cases, aspirin appears adequate but there are situations in which other anti-platelet drugs must be employed. […] By using antiplatelet drugs, mainly aspirin, the platelet hyperreactivity of patients can be reverted and that this translates into a low re-thrombosis rate.

Thrombophilias are hereditary and/or acquired conditions that predispose patients to thrombosis. Testing for thrombophilia is commonly performed in patients with venous thrombosis and their relatives; however such testing usually does not provide information that impacts management and may result in harm. […] We recommend that thrombophilia testing not be performed in most situations. When performed, it should be used in a highly selective manner, and only in circumstances where the information obtained will influence a decision important to the patient, and outweigh the potential risks of testing. Testing should not be performed during acute thrombosis or during the initial (3-month) period of anticoagulation. […] Testing for thrombophilias should only be performed when results will be used to improve or modify management. Testing has been suggested to assist with secondary prevention (determining the duration of anticoagulation following a thrombotic event); and for hereditary disorders, to aid in primary prevention in relatives of affected patients.

The majority of patients with venous thromboembolism (VTE) should not be tested for thrombophilia. Data supporting clinical usefulness and benefits are limited or nonexistent. […] Most patients with inherited thrombophilia can be identified by coagulation experts based on the patients personal and family history of VTE. Thrombophilia testing is usually not required. […] Do not perform thrombophilia testing at the time of a VTE event, as it can be inaccurate (often false positive). Perform testing (when indicated) after completion of initial therapy and if it might change management strategies. […] The goal of thrombophilia testing should be to aid decision making regarding future VTE prophylaxis, to guide testing of family members, and to determine the cause in severe or fatal VTE.

- #49 Dissecting the Complexities of Thrombophilia Screening – Hematology Advisorhttps://www.hematologyadvisor.com/features/thrombophilia-screening-dissecting-complexities-treatment-risk/
Investigations into the presence of inherited/acquired thrombophilia are primarily driven by the need to prevent or reduce associated morbidity and mortality. […] At this stage, evidence of thrombosis is taken as the basis for launching further investigations into possible causes in the hopes that appropriate prophylactic treatment may be administered. […] This means that thrombophilia screening, which may seem like a rational next step in all instances in which a clinician would like to rule out an identifiable etiology of thrombophilia, is potentially unnecessary or even harmful in some cases, especially when results do not meaningfully impact clinical decision making. […] Even though the debate on which clinical situations warrant screening for inherited thrombophilia remains unresolved, there is agreement that screening can be beneficial when it informs management.
- #50 Dissecting the Complexities of Thrombophilia Screening – Hematology Advisorhttps://www.hematologyadvisor.com/features/thrombophilia-screening-dissecting-complexities-treatment-risk/
Essentially, there are only 3 potential clinical decisions that can arise from thrombophilia screening: Whether treatment for the secondary prevention of VTE should be continued or discontinued. […] Deciding if anticoagulation prophylaxis is appropriate to lower the risk of thromboembolic events. […] Whether it would be desirable to withhold hormonal treatments that may heighten the risk of VTE among women. […] Should thrombophilia screening fail to lead to one of these 3 decisions, its cost-benefit ratio then tilts heavily towards the former and it should not be performed. […] The American Society of Hematology (ASH) has issued a series of screening criteria that are both wide-ranging and stringent. […] Thrombophilia screening should also be considered in ambulatory cancer patients with a family history of VTE or are known to have low-to-intermediate risk of VTE; this allows clinicians to assess whether pharmacological thromboprophylaxis would prove helpful.
- #51 Dissecting the Complexities of Thrombophilia Screening – Hematology Advisorhttps://www.hematologyadvisor.com/features/thrombophilia-screening-dissecting-complexities-treatment-risk/
In addition, screening is recommended in individuals with a family history of VTE or high-risk thrombophilia; the purpose of this is to assess if pharmacological thrombosis prophylaxis is necessary when transient thrombosis risk factors occur. […] These guidelines demonstrate that thrombophilia screening is most useful when it can lead to meaningful intervention that lowers the risk of thromboembolic events. […] Virtually all available guidelines are unanimous in advising against the routine ordering of coagulation factor tests to assess the risk of thrombosis. […] The BSH cautions against the blanket use of thrombophilia screening in all cases of thrombosis. […] Testing patients with VTE or relatives of patients with VTE and thrombophilia has a moderate to high chance of finding a positive test result, suggesting that the incremental value of knowing about the presence or absence of thrombophilia may be low.
- #52 Who should be tested for thrombophilia? | Genetics in Medicinehttps://www.nature.com/articles/gim920114
No general consensus exists in the medical profession as to which patients with venous thromboembolism (VTE) and which family members should be tested for thrombophilias. […] Thrombophilia testing remains a complex issue, difficult to condense in a short clear guideline. There are two valid reasons for the clinician to consider undertaking a thrombophilia workup in a patient with unprovoked (also referred to as idiopathic or spontaneous) VTE. […] Finding a thrombophilia in this patient population does not change that recommendation, and absence or presence of inherited thrombophilia has, therefore, not been used in the 2008 American College of Chest Physician guidelines as a major factor to guide duration of anticoagulation. […] This is the patient group where finding a strong thrombophilia, i.e., one that predicts a higher risk of recurrence, may be of relevance, where continued anticoagulation becomes beneficial and acceptable, despite an increased risk of bleeding or inconvenience. These are the patients I consider for thrombophilia testing.
