PROTHROMBIN-COMPLEX CONCENTRATE IN TREATMENT OF CLASSICAL HÆMOPHILIA WITH FACTOR-VIII ANTIBODY

They observed the outcome and drew three conclusions, the second of which was that maternofetal contamination was likely to have been transplacental because the babies had been born by caesarean section and immediately separated from their mother. Although transplacental infection may occur, these cases did not confirm it. It is wrong to suggest that cxsarean section is an "immaculate" delivery in which the baby is not contaminated by the mother’s blood.- Infection could have occurred during delivery.

the inhibitor titre has not been stated in these reports. We have treated 2 patients with classical haemophilia, who also have antibody to factor-vm, with the French prothrombinCase 1.-This 11-year-old boy had a very painful haemarthrosis of the right knee. Aspiration was performed under the cover of two injections of 44 units/kg of factor ix given at 4-hourly intervals. Complete clinical and functional resolution was obtained within 3 days. Case 2.-This 6-year-old boy had a post-traumatic haematoma of the left costal cardiac region. His hasmatocrit was 25%, and he received two injections of 28.5units/kg of factor IX at 4-hourly intervals. Bleeding stopped immediately. Within 5 days his haematocrit had risen to 31 %.
In both cases treatment was monitored by standard tests of haemostasis. Antibody titres were determined at intervals by a modification of the method of Biggs and Bidwell6 and expressed in units as previously described.7 Both patients showed a striking decrease in the kaolin-activated partial thromboplastin-time and the prothromin-time, still present 4 hours after the second injection. No evidence of disseminated intravascular coagulation was observed, since the platelet-count and fibrin(ogen)-degradation products were stable. Before treatment, neither patient had clinical or laboratory signs of liver disease. This treatment was followed by an anamnestic resoonse in both cases. Patient 1 had a pretreatment titre of 1.8units, which rose to 85 units 15 days after treatment. Patient 2 had a titre of 0.2 units before treatment, and after 15 days the antibody level was 0.8 units. Although no factor-vm antigen could be detected by rocket immunoelectrophoresis, the anamnestic response may have been due to the presence of small amounts of factor vm in the concentrate. These two observations confirm that non-activated factor-tx concentrate may be effective in controlling bleeding in patients with classical haemophilia complicated by antibody (inhibitor) and was used without thrombotic complication or disseminated intravascular coagulation. Although clinically active, this material can trigger an anamnestic response. Thus, (1) it is 1. Kurczynski, E. M., Penner, J. A. New Engl. J. Med. 1974, 291, 164. 2. Sultan, Y., Brouet, J.

SIR,—Dr Millward-Sadler and his colleagues (Nov. 22,
p.
1050) refer to the frequent association between serum-ot-antitrypsin deficiency and retention of the antitrypsin as diastaseresistant periodic-acid/Schiff (P.A.S.) positive globular inclusions within the cytoplasm of liver cells.’2 They report, however, two patients in whom liver-cell inclusions, morphologically identical to those seen in «,-antitrypsin deficiency, were associated with normal serum--a,-antitrypsin levels and phenotype. Immunochemical staining of the inclusions in these two cases was negative for «,-antitrypsin. Intracytoplasmic globular inclusions in liver cells have been reported under a variety of experimental conditions3-’ although the staining characteristics of the inclusions is not always recorded. In man, P.A.s.-positive intracytoplasmic globules are often found in hepatomas;6unfortunately a,-antitrypsin concentrations have not been recorded in such cases. Mallory illustrates a paper on alcoholic cirrhosis with a figure (his fig. 4) which depicts intracytoplasmic globular inclusions in liver cells, interpreted as decolorised bile.8 Globular inclusions ultrastructurally quite different from those of &agr;1-antitrypsin deficiency, but of similar morphology on light microscopy, have been described in a patient without evidence of K,-antitrypsin deficiency9 (serum electrophoresis normal, no relevant family history, but serum-cxcantitrypsin not determined during life). It seems, therefore, that the presence of diastase-resistant P.A.s.-positive globules in the cytoplasm of liver cells is not exclusively diagnostic of a,-antitrypsin deficiency. This appearance, on light microscopy, simply reflects the retention of a cell product with the appropriate staining characteristics as globular cytoplasmic inclusions similar to the Russell bodies that are most often found in plasma cells.
