    Notes: The clinical and immunologic response to a modified rapid (r) regimen of venom immunotherapy was evaluated and compared to a traditional (t) therapeutic regimen. Nineteen patients in the r group received a starting dose of 0.01 μg and reached a maintenance dose of 50 μg in 7 weeks. Twelve patients in the t group received an average of twenty-one injections on a weekly basis, reaching the same maintenance dose. The age and sex distribution and pre-treatment venom-specific IgE titres (RAST) of both groups were comparable.There were thirteen local reactions to venom therapy in both groups and no systemic reactions. Following therapy, most patients developed a rising titre of serum venom-specific IgG (V-IgG). Serum venom-specific IgE (V-IgE) changes were similar in the two groups; over half of the patients had a falling titre when on maintenance dose.Twelve patients were re-stung after reaching maintenance dose. Only one developed a mild systemic reaction, an individual who failed lo show a V-IgG response with rapid therapy. Five of nine patients did not have an anamnestic V-IgE response.This rapid method of venom immunotherapy appears to be safe, clinically effective, and comparable to traditional dosing without additional adverse reaction.

    Notes: In a double-blind study the therapeutic effect of a 4% disodium cromoglycate (DSCG) nasal solution was evaluated in thirty-nine patients with acute symptoms of ragweed hay fever. Patients were randomly assigned to the DSCG or placebo group as they presented with allergic rhinitis. Overall, the DSCG was not more effective than placebo in controlling the symptoms of rhinitis or in decreasing the need for concomitant antihistamines or corticosteroids. Among patients with the highest pretreatment serum ragweed-specific IgE (RW IgE) levels, drug-treated patients had some reduction in symptoms as compared to their placebo controls during the peak of the ragweed pollen season. DSCG treatment did not influence the usual seasonal rise in RW IgE. Side effects from both the active and placebo aerosols were frequent but mild.We conclude that DSCG nasal solution used for the treatment of seasonal ragweed allergic rhinitis is relatively ineffective.

    Notes: In 1979, pre-seasonal local nasal immunotherapy (LNIT) was found to be an effective treatment for ragweed hay fever. In 1980. this study was continued to evaluate the clinical and immunologic responses of a second year of LNIT. Patients received either pre-seasonal treatment with an unmodified ragweed extract (RW) or a polymerized ragweed extract (PRW), or no treatment. The results of the second year of treatment were the same as the first year. Adverse reactions were significantly higher in the RW-treated group than in the PRW-treated group (P 〈 0.001), Symptom/medication scores (SMS) in the RW-treated group were significantly lower than in the control group (P 〈 0.005). Although SMS in the PRW-treated group were lower than in the control group, this difference was not significant. The immunologic response was evaluated by measurements of serum (S) RW-specific IgE and IgG and nasal secretory (NS) RW-specific IgE, IgG, and IgA, After treatment, serum IgE titres and secretory IgA titres rose in the RW-treated patients. Nasal secretory-IgG and NS-IgA titres increased with PRW treatment. The only immunologic response observed in the control group was a rise in S-IgE titres after the ragweed season. There was no substantial difference in immunologic measurements observed in the 1979 and 1980 seasons, except that the pre-treatment NS-IgE level was higher in 1980 (P 〈 0.02). No significant correlations were found between antibody response and SMS. This study supports the efficacy of LNIT but does not support the protective role for NS-ragweed-specific IgA or IgG.

    Notes: The potency of various bee antigens including bee venom, several whole bee body extracts and fractions of bee venom was studied using the RAST inhibition method. As compared to whole bee body extract, bee venom was a much more potent inhibitor of both bee venom and whole body RAST, suggesting that venom has a greater capacity to bind specific bee IgE antibodies. Whole body extracts also varied substantially in their inhibiting activity. Phospholipase A and hyaluronidase were the most potent of the bee venom fractions suggesting their potential use as an assay for standardization of insect extracts.

    Notes: Following insect sting anaphylaxis, twenty-five patients of over 500 evaluated, did not have detectable serum venom-specific IgE. Twenty-two were evaluated within 1 year of the reaction, fifteen within 6 months. Anaphylaxis occurred in six patients after their first sting exposure. The clinical features of the sting reaction were typical of the reaction occurring in insect-allergic patients with serum venom-specific IgE. Eleven of the twenty-five patients had negative venom skin tests. These observations suggest that a non-IgE mechanism may be responsible for a minority of insect sting reactions.

    Notes: Measurements of serum venom specific IgE were used to gain further insight into the aetiology and natural history of stinging insect allergy. Several aspects were studied.(a) Following sting reactions, sequential sera were examined in the absence of venom immunotherapy. There was a marked individual patient variation in the persistence of venom specific IgE. In nine patients, antibody levels dropped to insignificant levels, suggesting the possibility that sensitivity can be lost spontaneously.(b) Details of four patients with anamnestic IgE antibody responses after sting reactions are presented. These responses occurred even when prior antibody titres were negligible, suggesting that patients mentioned above (No. 1) will require careful monitoring. The anamnestic responses are insect specific.(c) Eighteen patients were studied who had typical insect sting anaphylaxis and subsequent insignificant serum levels of venom specific IgE. One third also had negative direct skin tests with venom. These observations suggest that the possibility for a non-IgE pathogenesis for some insect sting reactions may have to be considered.(d) One patient was identified who became sensitized to non-venom protein in whole body insect extracts as the result of whole body extract therapy.

    Notes: Serum venom-specific IgE and IgG were monitored in twenty-three patients receiving venom immunotherapy for more than 3 years. Two response patterns of IgE antibody were found. Following initiation of therapy, seven patients had a rise in serum venom-specific IgE, peaking at one year, then decreasing. Sixteen patients had a persistent fall in IgE antibody titres following initiation of therapy. At the end of 3 years, levels of serum venom-specific IgE in both groups were comparable. The presence of atopy may have influenced the rising IgE antibody response.Serum venom-specific IgG either rose or remained elevated if the pretreatment titres were high. After several years of therapy, there was generally a decrease in serum venom-specific IgG.
