When patients allergic to penicillin develop life-endangering infections that require treatment with beta-lactam antibiotics, they face a fatal infection or the possibility of a fatal allergic reaction. We have approached this situation by using an oral desensitization procedure before full-dose antibiotic therapy. Thirty consecutive patients with histories of allergic reactions to penicillin, positive immediate wheal and flare skin-test reactions to penicillin determinants, and life-threatening infections were studied. Bacterial endocarditis requiring penicillin G therapy led to desensitization of 19 patients, Pseudomonas sepsis of pneumonia requiring treatment led to desensitization of nine subjects, and staphylococcal infections requiring therapy with a penicillinase-resistant penicillin led to desensitization of two patients. Penicillin G or carbenicillin were administered orally, beginning with 100 U or 60 microgram, respectively. At 15-min intervals, progressively doubled doses were given during continuous monitoring for the appearance of allergic reactions. Within 5 hr, full therapeutic doses were administered intravenously. Skin-test reactions disappeared or diminished in all 23 subjects who were retested after desensitization. Full courses of antibiotic therapy and cure of the infections were accomplished in 30 of 30 patients. No deaths, anaphylaxis, or severe acute allergic reactions occurred. Pruritic cutaneous eruptions appeared in nine patients (30%) 6 to 48 hr after the onset of therapy. One patient developed reversible nephritis 3 wk into therapy with penicillin G. The results of this study suggest that oral desensitization is an effective, relatively safe approach to administering beta-lactam antibiotics to penicillin-allergic patients with life-threatening infections.

Cefozopran (CZOP) was administered via intravenous injection to 9 patients (ages ranging from 1 month to 13 years) with pediatric bacterial infections, at daily dose levels between 56.7 and 200 mg/kg, divided into 3 or 4 doses. The following results were obtained. 1. Eight patients, including 1 with purulent meningitis, 1 with sepsis, 3 with acute pneumonia and 3 with lymphadenitis, were treated and subjected to clinical evaluation. Clinical effects were excellent in 6 cases and good in 2, with an overall efficacy rate of 100%. One case with pyoderma was not evaluated because of a combined use of an external antibiotic. 2. Organisms suspected as pathogens included 5 strains: 3 strains of Haemophilus influenzae, 1 strain of Staphylococcus aureus and 1 of Escherichia coli. Bacteriologically, all the strains were eradicated. 3. Side effects or abnormal laboratory test results were observed in 4 cases; wheal in 1 case, elevated GOT and GPT in 2 cases and eosinophilia in 1 case. 4. From the results described above, we considered that CZOP would be an effective drug for use in pediatric bacterial infections.

I. a. Pneumococcus polysaccharides, when injected intradermally into patients convalescent from pneumonia, are capable of eliciting a response. The polysaccharide inducing a cutaneous reaction was found always to be homologous in type to that of the pneumococcus causing the infection. b. The character of the reaction incited by the protein-free bacterial sugars is of the immediate wheal and erythema type. c. A patient's capacity to react was found to be intimately associated both with recovery from infection and with the presence of type specific antibodies in the circulating blood. II. a. The so-called nucleo-protein of pneumococcus, when injected intradermally, also causes a local cutaneous reaction in patients during convalescence from lobar pneumonia. b. The local lesion resulting from the injection of protein is tuberculin-like in character, and differs from that evoked by the type-specific polysaccharides in gross appearance, time of development, and duration. c. Individuals, acutely ill with and convalescent from pneumococcus pneumonia, possess in their circulating blood, precipitins reactive with pneumococcus protein. In the observations recorded, the concentration of anti-protein antibodies in the blood serum did not seem to influence the patient's capacity to react to intradermal injection of the protein.

The majority of patients convalescent from pneumonia due to Types I, II and III Pneumococcus develop at the time of recovery circulating antibodies for the homologous type of organisms. At the same time an immediate wheal and erythema reaction followed the intradermal injection of the homologous type-specific polysaccharide in 100 per cent of Type I patients, 58.8 per cent of Type II patients, and 44 per cent of Type III patients. In a group of 18 patients repeatedly tested with the type-specific polysaccharides, 10 developed in the second or third week of convalescence circulating antibodies for one or more heterologous types. In none of 21 control patients was this phenomenon observed. It is suggested that the development of circulating antibodies for heterologous types of Pneumococcus was associated with the previous intradermal injections of the type-specific polysaccharides.
