Effect of treatment with activated prothrombin complex concentrate (FEIBA) on factor VIII-antibody level.

The influence of treatment with an activated prothrombin complex preparation (FEIBA) on the antibody level was studied in 10 haemophiliacs with an antibody to factor VIII. The antibody level was observed to rise at least once in five patients, while in the remaining five patients no rise occurred. In all, 6 out of 31 treatments were followed by an anamnestic rise of the antibody level, corresponding to 19.4%. A rise of the inhibitor level following FEIBA treatment is likely to occur in patients who show a marked antibody rise after factor VIII treatment (good responders), but have a low antibody level at the time of treatment. High doses of FEIBA and simultaneous of red cells may also enhance the likelihood of an anamnestic response. Stimulation of antibody production is probably due to the presence of small amounts of factor VIII in this preparation.

[Splenectomy in idiopathic thrombocytopenic purpura: short- and long-term results (author's transl)].

The results of splenectomy in 25 patients with chronic idiopathic thrombocytopenic purpura (ITP) are reported. Splenectomy was performed when the platelet count was consistently less than 30,000/mm3 in spite of glucocorticoid therapy over an observation period of at least six months. Following splenectomy, 13 patients showed complete remission, 9 partial remission, whilst in 3 cases the condition was unaffected by splenectomy. It is not possible to predict a successful response to splenectomy on the basis of preoperative laboratory findings. A rise in thrombocyte count to over 400,000/mm3 during the first 2 weeks after splenectomy makes complete remission very likely.

[Sonography for clarify complications after renal transplantation (author's transl)].

The diagnostic value of the ultrasound method was studied via 170 individual examinations in 75 patients. The method is particularly well suited for an accurate determination of the location and size of the transplanted kidney and for demonstrating perirenal growing and displacing processes such as cystic lymphangiomas, haematomas and abscesses. In addition, ultrasound supplies information on the area covered by lacunae. However, the use of the method for diagnosing casting-off reactions is limited on account of the great variability of the dimensional parameters. It can be used without risk in followup studies of patients with transplanted kidneys, since it is a non-invasive method. It deserves preference among the possible methods of investigation, especially when growing and displacing processes have to be identified.

[Differential diagnosis of liver disease by means of sonography: correlation with scintigraphy and angiography (author's transl)].

The value of sonography of the liver is assessed and compared with angiography and scintigraphy on the basis of case material from 102 patients, representing localized and diffuse liver processes. The diagnostic accuracy depends on the characteristic acoustic impedance differences in the examined tissue. Diffuse liver disease and processes without clearly defined acoustic borderlines may cause diagnostic difficulties and differentiation can only be attempted by additional clinical information. Defined tumours represent the main field of application. The combined use of ultrasound, scintigraphy and angiography permits a correct diagnosis to be made in nearly 90% of cases. Differential diagnosis between cystic and solid processes is possible only by ultrasound.

[Antithrombin III deficiency and tendency to thrombosis (author's transl)].

Antithrombin III (AT III) was determined in 290 patients with deep venous thrombosis and/or pulmonary embolism by immunological methods (radial immunodiffusion, Laurell technique) and by biological activity (heparin cofactor activity and anti-Xa activity). Patients with venous thrombosis had a significantly lower AT III concentration, as determined by the immunological methods or biological method (heparin cofactor activity), than normal persons without any history of venous thrombosis. A decreased level of AT III was found in 27 patients. In these patients the immunoreactive antithrombin III was decreased to the same degree as biological activity (heparin cofactor activity or anti-Xa activity). Thirteen out of these 27 patients belonged to 9 families and, hence, congenital AT III deficiency can be assumed in these cases. The aetiology was unknown in the other half. Patients with AT III deficiency are prone to spontaneous and/or recurrent venous thrombosis. A high incidence of pulmonary embolism and particularly, of fatal pulmonary embolism is remarkable. In more than half of the patients the first thrombotic event occurred before the age of 35. The treatment of choice in such patients is with oral anticoagulants of the coumarin group.

[Synovectomy in the prevention of recurrent joint bleedings in haemophilia (author's transl)].

Synovectomy was performed in seven patients with severe haemophilia A, one with moderately severe haemophilia A and one with severe haemophilia B. Frequently recurring haemorrhages into one knee and demonstrated hypertrophic synovitis were the indications for operation in all. No serious bleeding complications occurred during or after the operations. After synovectomy the frequency of haemarthroses in the synovectomised joint decreased significantly. Satisfactory joint function was eventually achieved in all by gymnastic exercises and physiotherapy over a long period. The operation should only be done in large haemophilia centres were there is sufficient experience.

Sonography: a method for localization of hematomas in hemophiliacs.

Sonography was used to visualize hematomas in hemophilic patients. The method is especially helpful for the diagnosis of psoas hematoma and retroperitoneal hematoma and allows the follow-up of hematomas of the cervical region and muscle hematomas. The method is simple, rapid, painless and has no known adverse effects.
