Specific and total serum IgE measurements in the diagnosis of penicillin allergy. A long term follow-up study.
Kraft D, Roth A, Mischer P, Pichler H, Ebner H.
Sera from 204 patients with acute or former reactions following penicillin treatment were investigated by RAST with specificity for benzylpenicilloyl and phenoxymethyl-penicilloyl. The IgE antibody levels were followed up for of more than 2 years. Positive results could be observed at the time of the acute reactions and the weeks following; later months or years in many cases. Occasionally negative RAST results occurred within 30 days; on the other hand high levels of specific IgE persisted for years in some patients. Total serum IgE measured by RIST and the RAST results showed similar patterns, with mean levels of 568 u/ml between 0 and 30 days after the penicillin allergic reaction, 286 u/ml between 30 days and 1 year, and 195 u/ml in cases after 1 year corresponded well with the observed decline in specific IgE. Skin tests performed with penicilloyl-polylysine in 118 patients showed an overall correlation of 91-5% with the RAST results. Differences between the two test systems were observed in patients with a long interval between the test and the last allergic attack. None of the patients with proved penicillin allergy had atopic diseases or a history of atopy. On the basis of these findings it is suggested that the determination of both circulating specific IgE and total IgE should be of great value for diagnostic purposes during acute drug reactions and in the months immediately afterwards.

The gastrointestinal absorption of penicillin V in children with suspected coeliac disease.
Bolme P, Eriksson M, Stintzing G.
The gastrointestinal absorption of penicillin V (pc-V) was investigated in 6 children, 6-12 months old, with suspected coeliac disease. The diagnosis was set after small bowel biopsy and absorption tests of vitamin A and d-xylose. As control groups served 7 children with diarrhoea but with normal small bowel biopsy and/or absorption tests and a group of 9 children with upper respiratory tract infection of the same ages as the children in the test group. The absorption of calcium pc-V in oil suspension (Penicals) was impaired in the patients with suspected coeliac disease compared to that of the control groups. There was no significantly different absorption of pc-V between the control children with diarrhoea and those with upper respiratory tract infection. After 6-8 months of gluten free diet in the children with suspected coeliac disease their absorptive ability of oral calcium pc-V in suspension form was equal with that of a control group.

Erythromycin in respiratory tract infection.
Gould JC.
One of the main uses of erythromycin in respiratory tract infection has been in the treatment of acute streptococcal tonsillitis as an alternative to penicillin. Studies on the quantitative bacteriology of tonsils obtained at tonsillectomy have shown large numbers of both haemolytic streptococci and Haemophilus species in most samples and these organisms can be effectively reduced in number by preoperative treatment with antibiotics such as erythromycin. Such investigations suggest that erythromycin might have wider use in the treatment of respiratory tract infections, particularly where Haemophilus influenzae and other Haemophilus species are involved. Apart from specific infections such as those due to Mycoplasma pneumoniae, erythromycin is effective in the treatment of acute pneumonia due to organisms such as the pneumococcus, and this paper reports the further use of erythromycin in the treatment of acute exacerbations of chronic bronchitis where the clinical and bacteriological effects of treatment with this antibiotic are compared with those of ampicillin.
