[Delayed hypersensitivity to protamine and immediate hypersensitivity to insulin].

A 63-year-old female, with type II diabetes mellitus, diagnosed in 1967, was started on combination therapy with sulphonylureas and human depot insulin in May 1989, because of inadequate blood sugar control with sulphonylureas alone. Within 3 months she began to develop nodular skin reactions at the site of injection, 12-24 hours after insulin injections. Intradermal testing demonstrated delayed (Gell and Coombs type IV) hypersensitivity to protamine. No specific IgE or IgG antibodies were demonstrable. She was changed to protamine-free human delayed action insulin. After an initial reaction-free period, red urticarial lesions, attributable to immediate (Gell and Coombs type I) hypersensitivity to human insulin, appeared at the injection sites. There were no other complications with continued insulin therapy, and after about 6 weeks no further local reactions were detectable. When an allergic reaction to an insulin preparation is suspected, careful immunological investigation should be performed, to ensure adequate treatment without risk to the patient.

Effect of mattress encasings on atopic dermatitis outcome measures in a double-blind, placebo-controlled study: the Dutch mite avoidance study.

BACKGROUND: House dust mite (HDM) allergen might induce and maintain atopic dermatitis (AD). Reduction of allergen load by applying encasings might improve the clinical symptoms of AD. OBJECTIVE: We sought to investigate, in a randomized, double-blind, placebo-controlled study, whether reducing HDM allergen levels by using mattress, duvet, and pillow encasings for 12 months will result in improvement in AD symptoms. METHODS: Patients with AD (8-50 years old and allergic to HDM), having a Leicester sign score (a dermatitis score) of at least 1% extent and a severity score of 6 points or greater, were randomly allocated to an active (n = 45) or a placebo allergen-avoidance group (n = 41). Avoidance measures consisted of applying HDM-impermeable encasings for mattresses, pillows, and duvets for the active treatment group and cotton encasings for the placebo group. Effect on allergen concentrations (Der p 1 and Der p 1 plus Der f 1), Leicester sign score extent and severity, visual analogue scale scores for itching and sleeplessness, intradermal test results, atopy patch test results, total serum IgE levels, anti-Der p 1-specific IgE levels, and total blood eosinophil counts were studied. RESULTS: The active encasings reduced the Der p 1 allergen concentration in the mattress after 12 months with a factor 2.1 (P =.007) and the Der p 1 plus Der f 1 allergen concentration with a factor of 2.5 (P =.005); no significant change in allergen concentrations in mattresses was seen in the placebo group. Although the decrease in allergen load was significant, no differences in treatment-induced changes were seen between the placebo and active groups. CONCLUSIONS: Use of HDM-impermeable encasings resulted in a significant decrease in Der p 1 and Der p 1 plus Der f 1 allergen concentrations. However, this reduction in allergen load did not result in significant changes in clinical parameters between the groups. Reduction of allergens in other environments (work, school, and outdoors) might be equally important in improving symptoms of AD.

Hyaluronic acid skin fillers: adverse reactions and skin testing.

BACKGROUND: Hyaluronic acid (HA) fillers have been proposed as alternatives to other temporary skin fillers, such as bovine collagen, for treating facial skin lines and for providing lip augmentation. Several types of commercial HA fillers are now available in many countries. They include Restylane, which is produced by microbiologic engineering techniques, and Hylaform, which is HA extract derived from rooster combs. They have been approved for use in several countries, but not currently in the United States. There are no recommendations to perform pretreatment skin testing by the manufacturers. OBJECTIVE: Our purpose is to describe and comment on our experiences with Hylaform and Restylane fillers. Observation of any side effects and skin testing results were documented. METHODS: Between September 1996 and September 2000, 709 patients were treated with Hylaform and Restylane and were followed up clinically for at least 1 year. Three of these patients (0.42%) developed delayed skin reactions. Three other patients were referred for evaluation of their skin reactions from other practitioners. Five of these 6 patients agreed to skin testing of their forearms. RESULTS: In the 5 patients tested, challenge intradermal skin testing was positive in 4 patients; the reactions started approximately 8 weeks after injection. CONCLUSIONS: There was a slight incidence of delayed inflammatory skin reactions to two HA fillers. Both of these reactions occurred after the first and repeat injections. Challenge skin testing was positive in 4 of 5 tested patients.

Mycobacteria in pond waters as a source of non-specific reactions to bovine tuberculin in New Zealand.

When 71 samples were collected from ponds throughout New Zealand, 35 (49.3%) were found to contain mycobacteria. The majority of these strains (62.9%) belonged to a homogeneous group (tentative designation H-Group, which differed from any known mycobacterial species. Mycobacteria of this H-group had also been found in sphagnum vegetation growing in the immediate vicinity of many of the ponds. H-Group mycobacteria induce sensitization in guinea pigs against bovine tuberculin. The PPD sensitin prepared from these mycobacteria gave rise to larger reactions in guinea pigs than did bovine tuberculin when used in the same concentrations (500 and 50 TU). The possible sensitization of cattle to bovine tuberculin via drinking water containing H-Group mycobacteria, is discussed. The larger size of the delayed hypersensitivity reactions in guinea pigs using the same concentrations of bovine and homologous tuberculin, suggests that comparative intradermal testing might enable this non-specific reaction to be distinguished from the specific reaction developed during bovine tuberculosis infection in cattle.

Localized lymphatic sporotrichosis after fish-induced injury (Tilapia sp.).

Localized lymphatic sporotrichosis generally develops after the fungus Sporothrix schenckii is traumatically introduced into skin or mucosa by contaminated plant material. An 18-year-old male fisherman was injured by spines of the dorsal fin of a fish on the left third finger. The lesion became ulcerated, edematous and suppurative and did not respond to tetracycline and cephalexin. Fifteen days after the accident, a nodular lymphangitic pattern of swelling was observed. Histopathological findings and an intradermal test were suggestive of sporotrichosis and mycological cultures confirmed the diagnosis. The lesions resolved after oral treatment with potassium iodide. Sporotrichosis is a common subcutaneous mycosis in Brazil, and there is a previous report in the literature of this disease being acquired via trauma involving fish spines.

Baseline mycobacterial immune responses in HIV-infected adults primed with bacille Calmette-Guérin during childhood and entering a tuberculosis booster vaccine trial.

BACKGROUND: Most new tuberculosis vaccines will be administered as a booster to subjects primed with bacille Calmette-Guérin (BCG) during childhood. METHODS: We investigated in vivo and in vitro immune responses to mycobacteria in human immunodeficiency virus (HIV)-positive subjects in Tanzania primed with BCG during childhood and entering a tuberculosis booster vaccine trial. Tests included intradermal skin testing for Mycobacterium tuberculosis purified protein derivative (PPD) and Mycobacterium avium sensitin (MAS); lymphocyte proliferation assays and interferon (IFN)-gamma levels after stimulation with Mycobacterium vaccae sonicate (MVS), M. tuberculosis early secreted antigen (ESAT)-6, M. tuberculosis antigen 85 (Ag85), or M. tuberculosis whole-cell lysate (WCL); and determination of serum antibody to lipoarabinomannin (LAM). RESULTS: A total of 888 subjects with CD4 cell counts > or = 200 cells/mm3 were enrolled. PPD and MAS test results were positive in 34% and 30% of the subjects, respectively. Proliferative responses were detected as follows: MVS, 6%; Ag85, 24%; ESAT-6, 21%; and WCL, 59%. IFN-gamma responses were 2%, 6%, 12%, and 38%, respectively. LAM antibody was detected in 28% of the subjects. Subjects were more likely to have detectable proliferative and IFN-gamma responses if they had positive PPD test results or CD4 cell counts > or = 500 cells/mm3. Overall, 94% of the subjects had evidence of primed mycobacterial immune responses. CONCLUSION: Of HIV-positive BCG-immunized adults with CD4 cell counts > or = 200 cells/mm3 in Tanzania, 94% are primed for booster mycobacterial immunization.

Severe adverse cutaneous reaction to insulin due to cresol sensitivity.

We present the case of an 80-year-old lady known to be sensitive to chlorocresol (4-chloro-3-methyl phenol) who developed severe erythrodermic exfoliative dermatitis with atypical features 2 weeks after commencing subcutaneous insulin. All medications except insulin were stopped, without major improvement. It was noted that the insulin contained m-cresol (m-methyl phenol) so a parabens-based insulin was substituted. There was a significant improvement in her clinical condition within 72 hr. Further patch and intradermal testing to the insulin and m-cresol was planned, but she developed a nosocomial infection and died. We hypothesize that the adverse cutaneous reaction was a systemic manifestation of cresol sensitivity, given the rapid clinical resolution on changing insulins and the previously demonstrated sensitivity to chlorocresol, particularly as cross-reactivity between different low molecular weight methyl phenols is documented. Local injection site reactions and systemic side-effects including nausea, diarrhoea and vomiting have previously been reported with cresol-containing insulins, although to our knowledge, this is the first reported case of a severe cutaneous reaction. It is important to be aware of m-cresol as a potential allergen, as it is contained in most commercially available insulins.

Gold sodium thiomalate (GTM) induces hypersensitivity to thiomalate, the thiol carrier of GTM.

A case of the gold sodium thiomalate (GTM)-induced eruptions with thiomalate (TM) hypersensitivity was reported. A 61-year-old Japanese woman developed lichenoid and seborrheic dermatitis (SD)-like eruptions with alopetia, when the total dosage of GTM administered for rheumatoid arthritis became 110 mg. The eruptions slowly disappeared with pigmentation after discontinuance of the GTM therapy, and the resumption resulted in the development of similar eruptions. She showed a positive reaction to GTM in an intradermal test. She also showed a positive response to TM, which is the thiol carrier of GTM, in the patch test, but a negative one to metallic gold. After administration of auranofin (AF), she also developed the SD-like eruptions with hypersensitivity to metallic gold as well as AF on patch testing, but did not develop the lichenoid ones. Our animal experiments revealed an almost complete cross reaction between GTM and TM, but only a partial one between GTM and aurothioglucose, which have dissmilar structures in the carrier part for gold. Probable roles of hypersensitivity to TM and metallic gold, which are metabolites of GTM, were discussed, respectively, in the genesis of the GTM-induced lichenoid eruptions and the AF-induced SD-like eruptions.

Estrogen dermatitis that appeared twice in each menstrual period.

A 23-year-old woman presented with millet-sized red papules that were scattered over her chest and abdomen. She stated that since the age of 20, she had recurrently suffered from pruritic eruptions that coincided with ovulation and the time prior to menstruation, and that they persisted for a few days before vanishing spontaneously leaving some pigmentation. A skin biopsy specimen revealed spongiotic bullae in the epidermis and marked infiltration of lymphocytes accompanied by some histiocytes and eosinophils in the upper dermis. An intradermal test for conjugated estrogen showed an urticarial reaction that faded in about four hours. Although the test did not strictly meet the criterion (erythema to remain for more than 24 hours for papulovesicular eruptions), it was concluded that the timing of the episodes along with the result of the test suggested that a diagnosis of estrogen dermatitis was highly probable. There have been several reports of this condition since it was first reported as a distinct entity in 1995; but whatever the reasons, the flares were observed only before menstruation in these cases, despite the fact that the serum estrogen levels showed a double-peaked pattern during each menstrual period. This is considered to be a rare case of estrogen dermatitis that flared twice in each menstrual period. Limited improvement was noted in the symptoms even without treatment.

Eczematous infiltrated plaques to subcutaneous heparin: a type IV allergic reaction.

Two patients are described who had delayed reactions with eczematous plaques to subcutaneous injections of heparin. Subcutaneous challenge with high and low molecular weight heparin compounds were positive in both patients. Patch and intradermal tests with heparin were positive in one subject. Histological and immunohistochemical studies indicated that it was a type IV allergic reaction.

Foreign-body granuloma and IgE-pseudolymphoma after multiple bee stings.

We report a patient with an unusual combination of an eosinophilic foreign-body granuloma and a pseudolymphoma, with recurrent severe oedema on the forehead, after multiple bee stings. On immunohistology the foreign-body granuloma and lymphoid follicles reacted with monoclonal antibodies against the high- and low-affinity IgE receptors, and against IgE. Prick and intradermal tests with whole-body bee extracts showed positive immediate-type reactions. The eosinophilic granuloma formation and lymphoid follicles may have been induced by a combination of immune complex and cell-mediated hypersensitivity following antigen persistence. Although bee stings are common, as far as we are aware, this complex reaction pattern has not been reported previously.

Progesterone-induced urticaria: response to buserelin.

We report a 41-year-old Caucasian woman with polycystic liver and kidney disease, and a 9-year history of severe cyclical urticaria related to her menses. The urticaria was not adequately controlled by antihistamines or Prempak-C (conjugated oestrogens and norgestrel). Intradermal testing with progesterone was strongly positive at 30 min and 18 h. Buserelin, administered intranasally at doses of up to 800 micrograms daily, controlled the urticaria within 4 weeks, and she was completely symptom-free thereafter. She had therapy-induced amenorrhoea and occasional hot flushes. Unfortunately, her liver cysts progressively enlarged, and a right hepatectomy was performed in June 1992, but she died after complications 3 weeks later. Prior to this she had been free of urticaria for 6 months after starting buserelin. Buserelin, a gonadotrophin-releasing hormone analogue, may be useful in the management of progesterone-induced urticaria, in patients in whom conjugated oestrogens are contraindicated or unhelpful.

IgE antibodies to house dust, mite, animal allergens and moulds in house dust hypersensitivity.

Fifty-three patients were investigated by intradermal tests and Phadebas RAST and, in most cases, the serum IgE level was determined. They were tested for sensitivity to house dust, Dermatophagoides pteronyssinus, cat, dog, horse and mould allergens. All cases with IgE antibodies to house dust were found to have specific IgE to other tested allergens as well. Eighty-nine per cent of the patients being RAST positive for house dust were also positive for D. pteronyssinus and in the majority of those cases IgE antibodies to other allergens were detected. The results reaffirm previous findings that the mite is not the only allergen in house dust and that extract of house dust is a mixture of several allergenic substances, which make it less suitable for differential testing. It is concluded that serum IgE determination is of value as a screening procedure in the diagnosis and that the use of a number of specific allergens in RAST is valuable in pinpointing the offending allergen in house dust hypersensitivity.

Specific IgE antibodies in nasal secretion from patients with allergic rhinitis and with negative or weakly positive RAST on the serum.

Nasal secretions from eighteen patients with allergic rhinitis with a positive case history, intradermal test and nasal provocation test, but with negative or only weakly positive RAST (radioallergosorbent test) on the serum against a total of thirty-five allergens, were studied. In the RAST an immunosorbent-purified anti-IgE with DE2 specificity was used, which raised the detection limit. Nasal secretion was collected by washing the nasal mucosa with 0-9% and 18% NaCl solution respectively, and the latter secretion was also luophilized and concentrated. In ten cases RAST was slightly positive on the nasal secretion, and in three of the concentrated secretions the RAST value was higher than on the serum. In none of the serum or nasal secretion samples was RAST positive according to the cut off value for a positive result defined by the reference system used in Phadebas Rast. From these results it is concluded that RAST analyses of nasal secretion from patients with allergic rhinitis is of no appreciable value in routine clinical allergological diagnosis. However, the increased sensitivity of RAST obtained with isotope-labelled anti-DE2 may be useful in the serological diagnosis of patients with low grade allergy having low levels of IgE antibodies in serum.

Asthma due to Central American walnut (Juglans olanchana) dust.

The purpose of our study was to describe a case of asthma due to Central American walnut (Juglans olanchana) dust and to ascertain whether an IgE antibody mechanism was implicated. The subject was a 48-year-old man who developed asthma following exposure to Central American walnut dust. Although intradermal testing with an aqueous extract of walnut dust produced no response, inhalation challenge with the extract produced significant bronchoconstriction. Another asthmatic person exposed to the wood dust had a positive skin test, but did not respond to the bronchial challenge. A direct radioallergosorbent test (RAST) on both subjects showed no evidence of serum IgE antibodies to Central American walnut dust. Consequently, the mechanism responsible for the sensitivity to the walnut dust remains unknown.

Hypersensitivity to topical corticosteroids.

Contact hypersensitivity from topical corticosteroids is becoming increasingly recognized; it is present in 2-5% of the patients attending contact dermatitis clinics. The use of a corticosteroid series containing tixocortal pivalate 1% (petrolatum), to detect hypersensitivity to hydrocortisone, and other steroids 1% (ethanol), depending on local corticosteroid usage, detects the majority of cases of corticosteroid hypersensitivity. In selected cases, the use of intradermal tests further improves the diagnosis of corticosteroid hypersensitivity. Corticosteroid hypersensitivity occurs most frequently among patients with stasis dermatitis. However, corticosteroid hypersensitivity is also common in other types of dermatitis, occurring as frequently as hypersensitivity to several allergens (e.g. wool alcohols and colophony) in the European standard battery. Although hypersensitivity has mainly been reported with corticosteroids applied to the skin, reactions may also occur on mucosal surfaces, following systemic administration and with sex steroids.

Drug eruptions to contrast media in Japan.

BACKGROUND: In Japan, drug eruptions to nonionic iodinated contrast media have been reported since the products appeared on the market in 1986. OBJECTIVES: To evaluate this clinical finding, we analysed the number of patients with drug eruption to contrast media in our hospital from 1989 to 2003. METHODS: In total, 117 patients suspected of such drug eruptions were patch and intradermal tested with contrast media (as commercially sold). Those who tested positive were evaluated. RESULTS: Of the 117 patients, 69 patients (19 men; 50 women, mean +/- SD age 51.4 +/- 16.5 years, range 17-86) showed positive reactions to contrast media. The number was 6-13 annually from 1989 to 1995, and 1-4 annually from 1996 to 2003. CONCLUSION: Although our data suggest (but do not prove) that patients with drug eruption to contrast media decreased in number, this condition is still not rare in Japan. Higher annual exposure to contrast media, including pretesting, could play an important role in this observation.

Autoimmune progesterone dermatitis.

Hypersensitivity to progesterone is rare, but the occurrence of skin rash in the luteal phase of the menstrual cycle or during pregnancy should alert one to this possibility. The diagnosis can be readily confirmed by intradermal testing and is eminently treatable by ovulation suppression.
