Insights

Familial Mediterranean fever (FMF) is an autoinflammatory disease. Despite inflammation increasing clotting risk, thrombotic events are rare in FMF patients, possibly due to counterbalancing anticoagulant changes and colchicine treatment.

Area of Science:

  • Rheumatology
  • Genetics
  • Hematology

Background:

  • Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease.
  • FMF involves recurrent inflammatory episodes like fever, peritonitis, pleuritis, and arthritis.
  • Systemic inflammation can promote a prothrombotic state by altering coagulation factors.

Purpose of the Study:

  • To investigate the occurrence of thrombotic events in patients with Familial Mediterranean fever.
  • To explore potential explanations for the observed frequency of thrombosis in FMF.

Main Methods:

  • Literature review of current available studies on FMF and thrombosis.
  • Analysis of personal clinical experience with FMF patients.

Main Results:

  • Thrombotic events purely related to FMF are reported as very rare in the literature and clinical experience.
  • Acute FMF attacks involve both procoagulant and anticoagulant/antifibrinolytic changes.
  • Colchicine, the primary FMF treatment, may reduce inflammation and hypercoagulability.

Conclusions:

  • The low incidence of thrombosis in FMF patients despite inflammatory triggers suggests complex hemostatic regulation.
  • Concurrent anticoagulant and fibrinolytic activities may counteract the prothrombotic tendency during FMF attacks.
  • Colchicine's anti-inflammatory effects likely contribute to a reduced thrombotic risk in FMF management.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
