    Description / Table of Contents: Summary Complement fixation tests and precipitin reactions in agar with gliadin as antigen were compared in cases of celiac disease. Pseudopositiv reactions did not occur in 285 controll cases when the precipitin test of Ouchterlony was used, but were seen in two cases of 189 controlls with the complement fixation test. If only one of the two reactions was positive and this was considered as a sufficient proof for the formation of gliadin antibodies those were found in 11 of 12 cases of clinically confirmed celiac disease. In those cases the agreement of the two methods was good, but not so in not confirmed cases where complement fixation tests gave more positive results than the precipitin reaction. It is proposed to use both methods for diagnostic help and to repeat the tests if the reactions are negativ.
    Notes: Zusammenfassung Die Methoden der Komplement-bindung und der Präcipitinreaktion in Agar mit Gliadin als Antigen wurden vergleichend auf ihre Anwendbarkeit in der Diagnostik der Cöliakie geprüft. Beim Präcipitinversuch kamen pseudopositive Reaktionen bei 285 Kontrollen nie vor, bei der Komplementbindung zweimal bei 189 Kontrollen. Zwölf sichere Cöliakiefälle ergaben vergleichend geprüft acht bzw. neun positive Reaktionen, wobei die negativen Befunde für die beiden Verfahren nicht das gleiche Serum jeweils betrafen. Wurde die positive Reaktion in nur einer Methode als ausreichend betrachtet, so war das Ergebnis: elf positive Reaktionen auf zwölf Fälle. Während bei klinisch bestätigter Cöliakie die Übereinstimmung der beiden Methoden gut war, war dies bei den bloßen Verdachtsfällen nicht der Fall. Hier gab es bei der Komplementbindung mehr positive Resultate als bei der Präcipitinreaktion. Es wird vorgeschlagen, beide Methoden nebeneinander anzuwenden und sie bei negativem Ausfall zu wiederholen, wobei die gegebenen diätetischen Richtlinien einzuhalten sind. Als Antigen kann ein Glycerinextrakt aus Gluten verwendet werden, wenn gereinigtes Gliadin nicht zur Verfügung steht. Extrakte mit heißem Wasser geben zu viele pseudopositive Reaktionen.

    Notes: Summary In the present vaccination trial, 202 seronegative schoolchildren comprising both sexes and aged 11 to 12 years were vaccinated i.m. in the upper arm with either the subunit vaccine at a dosage of 600 CCA or 200 CCA or with a whole-virus vaccine at a dosage of 200 CCA, using the double-blind procedure. Both vaccines were prepared from the strain A/New Jersey/76 (x 5 3a-recombinant). The vaccination was followed four weeks later by a booster injection. In tests of local and systemic reactogenicity, it was found that at both dosages the subunit vaccine caused a low frequency of minor adverse reactions. The whole-virus vaccine was marked by a significantly higher rate of adverse reactions, whether of the local or systemic variety. The whole-virus vaccine had, however, a higher immunogenicity than the subunit vaccine, and due to the relatively high rate of adverse reactions it causes, it is not recommended for the vaccination of seronegative children. Because of its low reactogenicity, the subunit vaccine can be given at higher dosage, and it is a matter for consideration whether a better antibody response might not result from two booster injections.

    Notes: Abstract Screening for coeliac disease (CD) with serum antigliadin antibodies (AGA) was performed in 1032 diabetic children and adolescents. In 8 children CD had been diagnosed before study entry. Of the remaining 1024 children, 33 had an elevated AGA titre in the first serum sample. On follow-up an elevated AGA titre was confirmed in only 17 of 31 patients. Nine of the repeatedly positive patients underwent jejunal biopsy, and CD was diagnosed in two asymptomatic patients; both were positive for IgG- and IgA-AGA. Among 10 AGA-positive patients in whom biopsies could not be performed, only 1 showed IgA-AGA and thus carried a high risk for CD. From our results we estimate a prevalence of CD in Swiss and German diabetic children between 1.1% and 1.3%. Falsepositive AGA titres occurred significantly more often in patients with diabetes duration of less than 1 year. AGA testing teached a specificity of 99% if performed at least 1 year after the onset of diabetes. Children suffering from both diabetes and CD showed a diabetes manifestation at a significantly younger age than non-coeliac patients, whereas CD tended to be diagnosed at a remarkably late age.

    Notes: Abstract The diagnostic value of gliadin IgG, IgA and IgE antibody (AB) determinations using the fluorescent immunosorbent test was examined in 586 children with malabsorptive disorders and/or failure to thrive. All patients underwent jejunal biopsy and were on a gluten-containing diet. IgG AB were found in all patients (331/331) with untreated coeliac disease (CD) in our study, but IgA AB in only 295/331 (89%). Therefore a screening test based only on IgA AB determinations is not recommended. By contrast, 203 (80%) of 255 children with other malabsorptive disorders had no gliadin AB, 43 (16.5%) had only IgG AB and only 9 (3.5%) had IgG and IgA AB. IgE AB proved to be of no additional value as a diagnostic tool because they were found in a quarter of the children without CD. Statistical evaluation of combined IgG and IgA AB determination showed at least 96% sensitivity and a specificity of 97%. The subjective (“Bayesian”) probability that an actual patient with a given AB test result has CD, is considered: a patient very probably has CD in the case of positive IgG and IgA AB, and no CD in the case of a negative AB result. In the case of negative IgA AB but positive IgG AB the physician's judgement (“prior probability”) influences the (“posterior”) probability of CD for an actual patient. In contrast to IgG AB, IgA AB decline rapidly after the introduction of a gluten-free diet and may be used for diet control after diagnosis. Antibodies against cow's milk proteins, though present in 72% of the 331 patients with CD, are of no therapeutic significance in CD and are of no value for its diagnosis.

    Notes: Abstract The diagnostic value of the fluorescent immunosorbent test for IgG gliadin antibodies (FIST) has been investigated in comparison with the LIF test—the competence of the gluten subfractions B2 and B3 in releasing lymphokines from peripheral lymphocytes in vitro—in 96 patients with coeliac disease (CD) under various dietary conditions. In untreated children with CD during their first 2 years of life, the FIST showed 100% sensitivity with 95% specificity, whilst the LIF test showed only 70% sensitivity and 73% specificity. Therefore it can be concluded that the FIST as a screening test is superior to the LIF. In older children with a proved recurrence of the mucosal abnormality after reintroduction of a normal diet, only 44% showed increased IgG gliadin antibody titres whereas 70% proved to be positive in the LIF test. Under a controlled gluten challenge all six patients reacted with a distinct increase in gliadin antibody titres whereas the LIF test changed from positive to negative and vice versa without following any clear principle. These results emphasize the inadequacy of the LIF test as a diagnostic method, both in untreated CD and under controlled gluten challenge.

    Notes: Abstract Antibodies of various immunoglobulin classes to different cow's milk proteins were studied with the fluorescent immunosorbent test in 601 newborns, infants, children and adults (A). The antibody levels, expressed as the geometric mean (gm) of four antibody titres to casein, β-lactoglobulin, α-lactalbumin and bovine serum albumin, showed a clear dependence on age. They were compared with the antibody levels in children with cow's milk protein intolerance (C), other gastrointestinal disorders (B) and coeliac disease (D). The 20 children with cow's milk protein intolerance clearly differed (significance level 2×10-11) from those of the two control groups (A, B) insofar as the criterion adopted was not the titre against a single protein but the gm of the four antibody titres, and insofar as allowance was made for the age of the patients. All patients with cow's milk protein intolerance also showed elevated gm titres of IgE, IgA and IgM antibodies. However, since a number of children in the control groups also showed higher values, particularly with regard to IgE antibodies, the determination of the IgE, IgA and IgM antibodies adds little to the diagnosis and at best provides a further discriminatory aid. Although antibody titres fall immediately after placing the child on a milk-free diet, it is a matter of months before they become negative (titre 〈1∶20). After challenge titres rise again. In a longitudinal study of 25 children with acute gastroenteritis (E) it was shown that the antibody titres remained unchanged during and after the attack. This contradicts the often expressed opinion that the cow's milk antibodies frequently observed in healthy infants are induced as a consequence of gastroenteritis. In contrast to the other groups, all 26 children with proven coeliac disease (D) had antibodies to gliadin, irrespective of whether their gm cow's milk antibody titre was high or low.

    Notes: Abstract The effect of different feeding regimens, notably the use of hydrolysed cow’s milk formulas, on the development of allergic reactions and the development of cow’s milk protein-IgG antibodies is still disputed. We prospectively compared the development of allergic manifestations and cow’s milk protein-IgG antibodies in a total of 702 infants who were divided into six groups: 1. exclusively breast milk for at least 4 weeks (n = 206). 2. Breast milk plus initial partially hydrolysed formula (n = 104). 3. Breast milk plus extensively hydrolysed formula (n = 50). 4. Breast milk plus initial conventional cow’s milk formula (n = 73). 5. Conventional cow’s milk with or without breast milk throughout (n = 187). 6. Extensively hydrolysed cow’s milk formula for 2 months, followed by conventional cow’s milk (n = 82).

    Description / Table of Contents: Zusammenfassung Eine radioimmunologische Bestimmung von Virusantikörpern mittels eines an Mikrotiterplatten fest gebundenen Antigens wurde entwickelt zur Bestimmung von Mumpsantikörpern. Als Antigen diente ein käufliches Komplementbindendes Mumps-Antigen. Die Methode ist empfindlicher als die Hämagglutinationshemmung; sie liegt im Bereich der Empfindlichkeit der Virusneutralisation auf Hühnerfibroblasten. Ihre Anwendung ist vor allem geeignet für große Serien von Antikörperbestimmungen in Humanseren, z. B. im Zusammenhang mit Impfprogrammen.
    Notes: Summary A solid phase radioimmunoassay on microtiter plates was adapted for the estimation of mumps antibodies using commercially available complement-fixing mumps antigen. The sensitivity of the test is superior to that of hemagglutination inhibition and lies in the same range as the virus neutralization test performed on chick fibroblasts. The method is useful for screening large series of human sera, for instance in connection with vaccination programs.

    Description / Table of Contents: Zusammenfassung Bei erwachsenen Freiwilligen wurden Immunisierungsversuche mit lebenden Zytomegalieviren, welche durch 125 Passagen ausschließlich auf WI-38 Zellen attenuiert worden waren (TOWNE 125 Stamm), durchgeführt. Orale/nasale Applikation induzierte keine Antikörperbildung. Fluoreszierende IgG-Antikörper konnten bei allen zehn sero-negativen Probanden, welche die attenuierten Zytomegalieviren in einer Dosis von 103 TCD50 intramuskulär erhielten, vier Wochen nach Immunisierung gefunden werden. Zum Auftreten von IgM-Antikörpern kam es bei sieben der zehn Sero-Negativen. Klinisch traten nur geringfügige Lokalreaktionen und eine relative Lymphozytose auf. Es konnte keine Virusausscheidung nachgewiesen werden. Verschiedene bis jetzt noch ungeklärte Fragen müssen zuerst durch weitere „Impfversuche“ an Freiwilligen geklärt werden, bevor an eine generelle Durchimpfung weiblicher Adoleszenten gegen Zytomegalie gedacht werden kann.
    Notes: Summary Trials with live cytomegalovirus (TOWNE 125 strain), which was attenuated by 125 passages exclusively on WI-38 cells, were done in adult volunteers. No virus take occured after oral/nasal application. When 103 TCD50 was given intramuscularly an IgG antibody response was detected at four weeks in all of ten volunteers tested by immunofluorescence; an IgM response was found in seven. Only mild local side-effects and relative lymphocytosis were observed. No virus excretion was found. Many questions remain to be answered by further trials before a cytomegalovirus vaccine can be given to adolescent girls.
