An abnormal fibrinogen was found in a patient associated with disabling recurrent phlebitis and pulmonary emboli, pseudotumor cerebri, gout and endometriosis. The fibrinogen is characterized by (1) abnormal side-to-side and end-to-end polymerization, (2) abnormal fibrinopeptide release, (3) a delayed gamma-gamma dimerization of the non cross-linked fibrin, (4) a pH optimum of 7--7.8, and (5) a deviation from normal amino acid composition with regard to lysine, aspartic acid, glutamic acid and serine. Since no defect has been found in any of her three children, and since the prothromin and partial thromboplastin times vary from time to time, it is assumed that the defect is acquired. Liver disease, usually associated with acquired abnormal fibrinogen, has been excluded as an etiological cause since liver function tests and biopsy are completely normal.

A patient with factor XII deficiency, gout, and angioimmunoblastic lymphadenopathy (AIL) was seen initially for an acute myocardial infarction, gout, and unexplained urticaria. The patient eventually was found to have AIL and a prolonged partial thromboplastin time. There was no evidence of a circulating anticoagulant. A factor XII deficiency (Hageman factor) was discovered. The coexistence of a factor XII deficiency, AIL, and gout in the same person raises some interesting questions regarding the basic mechanisms of the inflammatory process.

A 62-year-old man with a typical history of gout was admitted to the hospital with left-sided hemiplegia. His serum uric acid level was 10.3 mg/dL, his partial thromboplastin time was 198 s, and his Hageman factor (factor XII) coagulant activity and antigen were less than 1% of normal. Aspiration of synovial fluid from his inflamed knee disclosed urate crystals and abundant leukocytes but an absence of Hageman factor antigen. The presence of acute gouty arthritis in a patient with Hageman trait challenges the role of Hageman factor in the pathogenesis of gouty arthropathy.

Lesinurad is a selective uric acid reabsorption inhibitor approved for use in combination with xanthine oxidase inhibitors for the treatment of hyperuricemia associated with gout. In vitro, lesinurad was shown to be a weak inhibitor of cytochrome P450 (CYP)2C9 and a weak inducer of CYP3A4. Warfarin is a widely prescribed oral coumarin-based anticoagulant commonly prescribed in gout patients. In an open-label clinical study in healthy adult male subjects, the effects of multiple daily doses of 400 mg lesinurad on the pharmacokinetics and pharmacodynamics of a single dose of 25 mg warfarin (racemic mixture of R- and S- enantiomers) were evaluated. Lesinurad had no effect on the absorption or the exposure (area under the concentration-time curve [AUC] and peak concentration) of the more active S-warfarin enantiomer. A slight reduction (19%) in overall plasma exposure (AUC) was observed for the R-warfarin enantiomer. Lesinurad had no meaningful clinical impact on anticoagulation activity as measured by prothrombin time, activated partial thromboplastin time, and international normalized ratio of prothrombin time and Factor VII clotting activity. Overall, the administration of warfarin in the presence of multiple-dose lesinurad was devoid of clinically significant drug-drug interaction.
