  • Prenatal diagnosis of hemophilia B by an immunoradiometric assay of factor IX

    • An immunoradiometric assay of factor IX was developed based on homologous antibodies that arose in a hemophilic patient. With this assay, 11 of 12 patients with severe hemophilia B had factor IX antigen levels below 1 U/dl and 6 patients with mild hemophilia B had various levels. Factor IX antigen in 8 fetuses (16th-20th gestational week) aborted for therapeutic reasons ranged from 1.8 to 10.0 U/dl. Six amniotic fluids contained 0.28-1.2 U/dl factor IX antigen. Using the immunoradiometric assay, we could diagnose hemophilia B prenatally in one fetus at risk. No factor IX antigen (< 0.2 U/dl) was detectable in the fetoscopic sample. After termination of the pregnancy, analysis of blood from the abortus confirmed the diagnosis of severe hemophilia B. We conclude that very sensitive immunologic assays, such as the one described here, will prove useful in prenatal diagnosis of severe hemophilia B, since determination of factor IX activity in fetoscopic samples is unrealiable because of possible contamination with thromboplastic material.

  • Effect of specific binding of human albumin, fibrinogen, and immunoglobulin G on surface characteristics of bacterial strains as revealed by partition experiments in polymer phase systems
  • 1980
  • Ingår i: Infection and Immunity. - American Society for Microbiology. - 1098-5522. ; 29:3, s. 879-885
  • Tidskriftsartikel (refereegranskat)abstract
    • Four strains of gram-positive cocci with different combinations of positive binding of human proteins were investigated with respect to changes in physicochemical surface properties after specific protein binding. Staphylococcus aureus Cowan I, two group A beta-hemolytic streptococci, and one group G streptococcal strain were studied; they represented three different combinations of reactivity for human serum albumin, human immunoglobulin G, and fibrinogen. Using single-tube partition of bacterial cells in a dextran-polyethylene glycol system of constant polymer concentration but varying ionic compositions, it was possible to detect changes in the partition of bacteria after specific protein binding. There was a correlation between the binding of radiolabled human proteins to the bacterial strains and the effect of human proteins on the partition of the bacteria in the phase systems. Thus, the specific binding of proteins to the bacteria changes their physicochemical surface properties. These types of bacteria-protein interactions may play an important role in modulating host-parasite relationships.

  • High isolation rate of Branhamella catarrhalis from the nasopharynx in adults with acute laryngitis
  • 1980
  • Ingår i: Scandinavian Journal of Infectious Diseases. - Informa Healthcare. - 1651-1980. ; 12:4, s. 277-280
  • Tidskriftsartikel (refereegranskat)abstract
    • Branhamella catarrhalis was isolated from the nasopharynx in 55% of 40 noncompromised adult patients suffering from acute laryngitis. Diplococcus pneumoniae and haemophilus influenzae were found in another 5 and 8%, respectively; one patient had group A streptococci in the throat specimen. In 90% of the patients the laryngitis complaints were preceded by symptoms of an acute respiratory tract infection. Two of the patients with B. catarrhalis showed a significant titre conversion against influenza B and parainfluenza type e virus, respectively. Attempts to isolate virus failed in all cases. The results indicate that B. catarrhalis, known to cause acute otitis media in small children and respiratory tract infections in adult compromised hosts, may be involved in the etiology of acute laryngitis in otherwise healthy adults.

  • [Comparison between hysterosalpingographic findings and lesions observed by laparoscopy and laparotomy (author's transl)]. Vergleich zwischen Hysterosalpingographie, Laparoskopie und Laparotomie.
  • 1980
  • Ingår i: RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin. - 1438-9029. ; 133:5, s. 510-3
  • Tidskriftsartikel (refereegranskat)abstract
    • Laparoscopy and/or laparotomy had been performed in 91 patients also examined by hysterosalpingography (HSG) during two years. The comparison of the radiological and the operative findings shows, that total occlusion and hydrosalpinx are radiological signs of adhesions in the pelvis. A depot of contrast medium remaining around the fimbriated end of the oviduct is also a sign of adhesions. More than half of the patients with adhesions surrounding the oviducts and/or endometriosis had however normal hysterosalpingograms. Thus, the radiological examination, hysterosalpingography, has a low sensitivity rate concerning pelvic abnormalities.
