Fever as a risk factor for increased response to vitamin K antagonists: a review of the evidence and potential mechanisms.
Numerous factors affect the response to vitamin K antagonists (VKA) including age, dietary vitamin K, other drugs, pharmacogenetics, and disease states. In antithrombotic guidelines, fever is mentioned as a factor that may increase response to VKA. The purpose of this article is to review the available evidence regarding the effect of fever on response to VKA, and to discuss possible mechanisms of this effect. We performed a search of the English literature from 1943 to June 2014, using the key words fever AND warfarin, acenocoumarol, phenprocoumon, coumarin anticoagulants and VKA; fever AND vitamin K dependent clotting factors II, VII, IX, and X. One animal investigation and 6 studies in humans suggest fever increases response to VKA, but one study did not find a significant effect. The magnitude of this effect is variable. Possible mechanisms for the increased effect of VKA associated with fever are increased catabolism of vitamin K dependent clotting factors, decreased vitamin K intake, and inhibition of VKA metabolism. More rigorous studies are needed to confirm that fever increases response to warfarin and other VKA.

Randomised trial of a clinical dosing algorithm to start anticoagulation with phenprocoumon.
Prospective validation of two algorithms for the initiation of phenprocoumon treatment.. Inpatients with new-onset anticoagulation were randomised to one of two computer assisted dosing algorithms, or to a control arm. The primary outcome measure was the time to achieve therapeutic anticoagulation without overshooting (INR >4.0 within 10 days). Secondary outcomes included overshooting INR values, death, or bleeding within 30 days. In addition, predictors of the dosing algorithms for the loading dose and the maintenance dose including genetic parameters were reassessed.. 105 patients were randomised to arm A, 103 to arm B and 93 to the control arm. Arms A and B needed a median of 7 days to reach a therapeutic INR, arm C 6 days (p = 0.5). Overshooting INR was observed in 3.8%, 1.9% and 4.3% respectively (p = 0.6). Bleeding was found in 0%, 1.9%, and 5.4% (p = 0.06) and 30-day mortality was 0%, 1%, and 2.2% respectively (p = 0.2). VKORC1:c.-1639 G>A was associated with lower loading doses whereas VKORC1:c.-1453 G>A needed higher doses. VKORC1:c.-1639 G>A was also associated with lower maintenance doses.. Both algorithms allow safe initial dosing of phenprocoumon but they are not superior to anticoagulation by trained physicians. Dosing aids for coumarins with readily available clinical parameters may nevertheless be helpful for use in polymorbid hospitalised patients. Clinical data and the INR-response to treatment provides powerful information and delaying initiation of anticoagulation while awaiting genetic tests is not expected to increase drug safety.

[Coumarin-induced necrotic purpura of the skin -- case report and review of the literature].
We report the case of a 28-year old woman with extensive red-black colored lesions of the skin on the left thigh, which appeared without trauma. The disease arrived during longterm coumarin therapy because of a deep vein thrombosis and an antiphospholipid syndrome. After consideration of the differential diagnoses and due to the typical clinical picture we made the diagnosis of coumarin necrosis. We review the clinical and therapeutic features for this rare complication.

Patients with an ApoE epsilon4 allele require lower doses of coumarin anticoagulants.
Vitamin K is an essential cofactor for the synthesis of several blood coagulation factors. It has been suggested that the apolipoprotein E (ApoE) genotype has profound effects on vitamin K status. Therefore, we investigated whether this common genetic polymorphism influenced dose requirements and effects of coumarin anticoagulants.. We did a cohort study in 1637 patients from an outpatient anticoagulation clinic treated with acenocoumarol or phenprocoumon.. To attain the same level of anticoagulation, patients with genotype epsilon4/epsilon4 and genotype epsilon3/epsilon4 required respectively 3.4 mg (95%CI: -6.0 to -0.9) and 0.8 mg (95%CI: -1.6 to 0.1) acenocoumarol per week less than patients with genotype epsilon3/epsilon3. Patients homozygous for the epsilon2 allele required 3.5 mg (95%CI: 0.1 to 6.9) acenocoumarol per week more than patients with genotype epsilon3/epsilon3. The acenocoumarol maintenance dose showed a gene dose effect of the epsilon4 allele, but not of the epsilon2 allele. No significant dose difference was observed for phenprocoumon, possibly because of low numbers.. The ApoE genotype affects the dose requirements of acenocoumarol.

[The clinical course of coumarin-induced necrosis].
In three patients painful reddening of a well-circumscribed area of the skin occurred within five days of starting anticoagulant treatment with phenprocoumon (Marcumar), and within a short time it developed into a full-blown picture of coumarin necrosis. The indication for phenprocoumon was, in the first patient (a 29-year-old mother lying-in after her second child had been born) an increased platelet count and the presence of high risk factors for thromboembolism. In the second patient (25-year-old man) and the third one (45-year-old woman) it was secondary prophylaxis after pulmonary embolus and deep-vein thrombosis, respectively. All three patients were very obese and had a drug allergy, as well as other allergies (bronchial asthma in Cases 1 and 2; allergic rhinitis in Case 3). Phenprocoumon was at once discontinued in all three patients and low-dose heparin administration (Cases 1 and 3) or dextran infusion (Case 2: heparin intolerance) started. All three needed excision of the necrotic tissue with grafting to the skin defect. The coexistence of obesity and allergic diathesis may thus present an especially high risk for coumarin necrosis.
