A case of contact urticaria associated with a serous rhinitis, dyspnea, wheezing, and a dry cough appearing after the application of a hair conditioner on the scalp is reported. Prick test results with the conditioner diluted at 1/16 and 1/8 were strongly positive (+3), as well as a prick test (+3) with one component of the conditioner called "hydrolyzed proteins," which contained hydrolyzed bovine collagen and stearyl trimethylammonium chloride.

Hypersensitivity to natural rubber latex (NRL) in health care personnel exposed to powdered latex gloves appears as conjunctivitis, rhinitis, nasal congestion, cough, dyspnea, or bronchial asthma in approximately 30% of all cases with latex allergy while most of the patients have contact urticaria. The purpose of the present study was to determine the prevalence of latex-induced allergic rhinitis in health care workers using NRL gloves on a daily basis. Clinical examination accompanied by skin prick test (SPT) with latex glove extracts and common aeroallergens, measurements of specific IgE to NRL, and lung function tests were performed in 25 symptomatic workers and 11 latex-exposed asymptomatic controls. Sensitization to NRL was detected using SPT in one (4%) of 25 symptomatic workers but not in any of the asymptomatic controls. Positive SPT to aeroallergens was demonstrated in 8/25 symptomatic workers and 6/11 controls. Measurements of forced vital capacity, forced expiratory volume in I sec, and bronchial methacholine challenge did not show any significant differences between the study groups. In conclusion, NRL-aeroallergen-induced occupational rhinitis may occur among physicians and nurses who have a frequent use of latex gloves on a daily basis at hospital work. However, a relatively low prevalence of NRL-induced occupational rhinitis is associated with profuse consumption of no-powder sterile gloves.

In a retrospective analysis, 79 allogeneic bone marrow recipients treated with AmBisome prophylactically or because of proven or suspected invasive fungal infection (IFI) were evaluated in 92 episodes. The median duration of treatment was 14 (range 1-112) days. The mean maximum dose given was 1.64 +/- 0.8 mg kg-1 day-1 and the mean total dose was 1.29 +/- 2.28 g. The overall incidence of reported adverse events was 194, of which none had a serious outcome. In six cases, the drug was withdrawn as a result of toxic or allergic reactions: dyspnoea and flush (3), urticaria (1), cholecystitis (1) and disorientation (one case, probably not related to AmBisome). No anaphylactoid reactions were seen. Laboratory findings, including low serum potassium (48% of the episodes), increased serum creatinine (38%) and increased serum sodium levels (7%), caused no major clinical problems. Thirteen cases of verified IFI were evaluated regarding the efficacy of AmBisome. Survival or cure of the mycotic infection occurred in 5/13 patients (38%). Two patients were treated with AmBisome (3.6 and 3.3 mg kg-1 day-1) because of verified IFI before BMT. One died of IFI. The other died of venoocclusive disease of the liver (VOD) without histological evidence of active IFI. We found a significant (P < 0.05) reduction in autopsy-proven IFI, 12/199 (6%) compared to the period when only conventional doses of amphotericin B were used, 26/227 (11%).

We retrospectively studied anaphylaxis in an A&E department from computerized records. In 1993 (Study A), of 55,000 patients seen in casualty, nine had severe anaphylaxis (ANA) with loss of consciousness (LOC) or fainting (about 1: 6000). Fifteen had generalized allergic reactions (GR) without LOC or fainting, but including dyspnoea due to laryngeal oedema or asthma, angioedema and/or urticaria. Thus there were 24 (about 1:2300) generalized reactions involving hypotension and/or respiratory difficulty. A further case diagnosed as hyperventilation syndrome was probably a wasp sting GR. Six cases of urticaria and/or angioedema were also identified. Of the nine with ANA, a possible cause was identified in eight (3 stings; 2 drugs; 3 foods). There was delay in arrival in A&E: hypotension was noted in three and had resolved spontaneously in six. Only 3/9 were related with adrenaline: i.v. hydrocortisone and chlorpheniramine was the mainstay of treatment. No investigation was recommended nor advice given on future management. Four patients were later referred to our allergy clinic by their GPs. In study B (aug-Oct 1994), nine cases of ANA were identified (1:1500), eight due to bee or wasp stings. The increased incidence was probably related to more detailed history-taking. Only three were treated with adrenaline. The use of adrenaline for future anaphylaxis was discussed with six patients, and five were referred to our allergy clinic. A reaction to the same allergen had occurred previously in 24%. Improved awareness of anaphylaxis and its management is necessary.

The anti-CD25 immunotoxin (IT), RFT5-SMPT-dgA, was used in a phase I dose escalation trial in patients with refractory Hodgkin's lymphoma. The IT was constructed by linking the monoclonal antibody RFT5 via a sterically hindered disulfide linker to deglycosylated ricin-A. All patients in this trial were heavily pretreated with a mean of 5 (range, 2 to 8) different prior therapies, including autologous bone marrow transplantation in 8 of 15. The mean age was 29 years (range, 19 to 34 years). Thirteen of 15 patients had advanced disease (stage IV) with massive tumor burdens and 6 of 15 had B symptoms. The IT was administered intravenously over 4 hours on days 1, 3, 5, and 7 for total doses per cycle of 5, 10, 15, or 20 mg/m2. Patients received one to four cycles of treatment. The peak serum concentration of intact IT varied from 0.2 to 9.7 micrograms/mL. The serum half life (T1/2) of the IT ranged from 4.0 to 10.5 hours (mean, 6.1 hours). Side effects were related to vascular leak syndrome (VLS), ie, decreases in serum albumin, edema, weight gain, hypotension, tachycardia, myalgia, and weakness. Two patients had a National Cancer Institute (NCI) grade 2 allergic reaction with generalized urticaria and mild bronchospasm. At 15 mg/m2, 1 patient experienced a grade 3 myalgia. All 3 patients receiving 20 mg/m2 experienced NCI grade 3 toxicities (edema, nausea, dyspnea or tachycardia) and 1 patient had NCI grade 4 myalgia. Thus, the maximal tolerated dose was 15 mg/m2. Seven of 15 patients made human antiricin antibodies (> or = 1.0 microgram/mL) and 6 of 15 developed human antimouse antibodies (> or = 1.0 microgram/mL). Clinical response included 2 partial remissions, 1 minor response, 3 stable diseases, and 9 progressive diseases. As has been predicted from the preclinical tests, these data seem to indicate clinical efficacy of this new IT in heavily pretreated Hodgkin's patients, thus warranting further clinical investigation.

Hypersensitivity resulting from the ingestion or inhalation of buckwheat allergen causes immediate manifestation of symptoms including urticaria, wheezing, dyspnea, anaphylactic shock, which is considered to be IgE-mediated type I hypersensitivity. Using sera of patients with buckwheat allergy the immuno-reactivity to purified buckwheat protein was investigated by enzyme-linked immunosorbent assay (ELISA) and immunoblotting method. The incidence of positive RAST value to buckwheat was 80% in the patients and 66.6% in the RAST-positive controls, whereas the RAST-negative controls showed all negative. The sera of both patients and RAST-positive controls showed significantly higher levels of specific IgG antibodies against salt-soluble and salt-insoluble fractions of buckwheat protein than the RAST-negative controls. By means of IgG-immunoblotting analysis, ten polypeptide bands of salt-soluble fraction and six polypeptides bands of salt-insoluble fraction were detected in all sera of the patients. In contrast, the patterns of IgE-immunoblots varied depending on the sera used. Taken together, the immune activation to buckwheat protein in patients with buckwheat allergy is not restricted to IgE antibody formation but extends to other immunoglobulin class. IgG, which indicating that the overall immune activation to buckwheat protein may be the basic characteristics of buckwheat allergy. Additionally, other factor is necessary for the manifestation of symptoms.

It has recently been published patients suffering from urticaria or anaphylaxia induced by nematodes usually parasitizing fishs or cephalopode, in whom, Anisakis simplex (AK) sensitization prevalence was detected up to 37%. We tried out a prospective study to evaluate the presence of AK specific-IgE in an asthmatic population, comparing to other group of patients with urticaria. Complaints related to food ingestion were recorded in both, and dietetic measures were advised. Thirteen patients (13/66; 20%) showed AK specific IgE. Nine of them were asthmatics (p < 0.01), and only 4 suffered from urticaria. Four patients, three of them asthmatics, could link symptoms after fishs, cephalopode or, surprisingly, seafood intake, including epigastralgia, rhinorrhea, conjunctivitis, hives, and dyspnea. Atopia was not a consistent status, only five AK sensitized patients also did to common inhalants (all skin prick-test positive to house dust mites). Asthmatic AK-sensitized patients were older than non AK-sensitized asthmatics (46.23 vs 30.1; p < 0.05). The way of sensitization could be inhalative or through digestive mucosa parasitization by live larvae. Possibility that an AK allergen can play a role in adult asthma, should be considered specially in countries with high fish or seafood diet content.

Two women aged 29 and 27 years, with complaints ranging from itching and swelling during or after cohabitation to anaphylactic symptoms comprising generalized urticaria, angioedema and dyspnoea, were found to be allergic to human semen. The total amount of serum IgE had increased in both, and the amount of semen albumin-specific IgE in one of them; both showed a positive reaction to an intracutaneous test with seminal plasma. The women were given a course of hyposensitization treatment, after which the problems disappeared.

In four patients, two women aged 40 and 42 years and two men aged 49 and 37 years, type I allergy to Ficus benjamina was established. Two patients had been sensitized by contact with these pot plants at their homes. The other two patients were plant growers. F. benjamina is a non-flowering, currently very popular pot plant to be found in both private houses and public buildings. The symptoms comprise itching and swelling of the eyelids, tears, running nose, wheezing and dyspnoea. In one plant grower contact urticaria progressing to dermatitis of the hand was the main symptom. Only one patient had a clear-cut atopy. Both plant growers showed a cross-allergy to other Ficus species. Two patients had a cross-allergy to latex and the associated cluster of tropical fruit (banana, kiwi, avocado, and chestnut). Removal of the ficus plants from the homes and change to another crop or to another occupation completely resolved the complaints of these patients.

Eight glove-wearing hospital personnel were evaluated for suspected type I-like allergic manifestations due to corn-starch powder. All subjects were clinically examined, the presence of atopy was assessed by administration of a questionnaire, the on-off test was verified (the clinical feature behavior was verified with regard to the beginning and the cessation of the work shift), levels of specific serum IgE for maize and latex were measured, and prick tests for the same allergens were performed. The on-off test was positive for everyone. The symptom associated with glove use was urticaria, which was also associated in one case with intermittent dyspnea and in another with oculorhinitis, angioedema, and asthma. Five workers were atopic. The serum IgE test found three positive responses to maize, three positive responses to both latex and maize, and two negative responses to both. However, in the two patients testing negative to IgE, the prick tests were positive: one for maize and the other for both maize and latex. All workers evaded further relapses by avoiding exposure to powdered gloves. There is general agreement that corn-starch powder may cause irritant dermatitis and that it may be a vehicle for other allergens. This study seems to suggest that corn-starch powder may act as a type I allergen itself. Further studies on a larger number of subjects and further research on the chemical properties of corn-starch powder, in particular on its protein content, are needed to confirm this hypothesis.
