SummaryIn human plasma, heparin cofactor II (HCII) is a thrombin inhibitor, whose deficiency has been reported to be associated with recurrent thrombosis. The finding of two cases of low plasma HCII activity in two patients infected with the human immunodeficiency virus (HIV) led us to investigate this coagulation inhibitor in the plasma of a larger population of HIV-infected patients. The mean plasma HCII activity was significantly lower in 96 HIV-infected patients than in 96 age- and sex-matched healthy individuals (0.75 ± 0.24 vs 0.99 ± 0.17 U/ml, p <0.0001). HCII antigen concentration was decreased to the same extent as the activity. The proportion of subjects with HCII deficiency was significantly higher in the HIV-infected group than in healthy individuals (38.5% vs 2.1%). In addition, HCII was significantly lower in AIDS patients than in other HIV-infected patients, classified according to the Centers for Disease Control (CDC) on the basis of an absolute number of circulating CD4+ lymphocytes below 200 x 106/1. The link between HCII and immunodeficiency is further suggested by significant correlations between HCII activity and both the absolute number of CD4+ lymphocytes and the CD4+ to CD8+ lymphocyte ratio. Nevertheless, the mean HCII level was not different in the various groups of patients classified according to clinical criteria, except in CDC IVD patients in whom HCII levels were significantly lower. In addition, no correlation could be demonstrated between HCII and protein S activities, another coagulation inhibitor whose plasma level was also found to be decreased in HIV-infected patients. A similar prevalence of HCII deficiency was also found in a small series of 7 HIV-infected patients who developed thrombotic episodes, an unusual complication of the infection. This suggests that, in HIV-infected patients, HCII deficiency is not in itself the causative factor for the development of thrombosis.

The Right

The presence of a pathologic mass in the right ventricle (RV) may lead to hemodynamic consequences and to a life-threatening incident of pulmonary embolism. The diagnosis of an unstable thrombus in the right heart chamber usually necessitates intensive treatment to dissolve or remove the pathology. We present a report of an unusual complication of severe ketoacidosis: thrombus in the right ventricle, removed from the tricuspid valve (TV) apparatus. A four-year-old boy was diagnosed with diabetes mellitus (DM) type I de novo. During hospitalization, a 13.9 × 8.4 mm tumor in the RV was found in a routine cardiac ultrasound. The patient was referred for surgical removal of the floating lesion from the RV. The procedure was performed via midline sternotomy with extracorporeal circulation (ECC) and mild hypothermia. Control echocardiography showed complete tumor excision with normal atrioventricular valves and heart function. Surgical removal of the thrombus from the tricuspid valve apparatus was effective, safe, and a definitive therapy for thromboembolic complication of pediatric severe ketoacidosis.<br /><br />

Grisel’S Syndrome

Objective: “La maladie de Grisel” (Grisel's syndrome) is a spontaneously occurring atlantoaxial subluxation with torticollis. We present a case of atlantoaxial subluxation occurring in a 20-year period of pharyngoplasty surgery. The occurrence of a “spontaneous” atlantoaxial subluxation after oral cavity or pharynx operations is rare. Because some neck pain and stiffness are commonly seen after these kinds of operations, we would like to draw attention to this unusual complication. Symptoms associated with a torticollis after an operation in the oral cavity or pharynx requires additional investigation to exclude this rare complication. A review of the available literature concerning etiology and treatment of la maladie de Grisel is presented.
