    Allergy to Dermatophagoides pteronyssinus was determined in 61 rhinitis patients using prick test (PT), enzyme-immunoassay (EIA) and enzyme-linked immunosorbent assay (ELISA). A total of 43 patients tested positive with PT. Forty six patients were positive when tested with EIA and ELISA. With PT as standard test, EIA was found to have 83.7% sensitivity and 44.4% specificity; ELISA had 81.4% sensitivity and 38.9% specificity. There was a linear relationship between absorbance values obtained by EIA and ELISA. The performance time was 8 hours, 24 hours and 30 minutes for ELISA, EIA and PT respectively. The cost per test for ELISA, EIA and PT was US$ 0.20, US$ 5.20 and US$ 0.14 respectively. It was concluded that ELISA was more cost-effective than EIA should be used to supplement PT for a more complete diagnosis of allergy.

    Infants, one to 56-weeks-old, presenting with persistent diarrhoea were placed on a diet free of cow's milk protein which improved their clinical condition. Six weeks later, 67 infants were challenged with a low-lactose cow's milk formula and jejunal biopsy was taken before and 24-hours after challenge. On the basis of histological changes in the intestinal mucosa and development of clinical symptoms the infants were categorised into three groups: Group 1 (n = 16) with no clinical or mucosal abnormality, Group 2 (n = 20) with mucosal abnormality but lacking clinical symptoms, and Group 3 (n 31) with manifestation of mucosal abnormality and clinical symptoms. In addition to the total IgE the radioallergosorbent test (RAST) was performed on sera from the infants taken before and after milk provocation. The mean total serum IgE level ranged from 288 to 560 IU/ml. In Groups 2 and 3 the prechallenge serum IgE levels were significantly higher than the postchallenge levels but in Group 1 the levels remained unchanged on challenge. A positive RAST to milk proteins was observed in five infants (7.4%), that is, one in Group 2 and four in Group 3, of 67 infants studied. In a survey of 405 consecutive paediatric-age patients admitted for a variety of symptoms, 90 were positive for RAST specific for milk proteins. Interestingly the majority of the patients positive for RAST presented with gastrointestinal ailments. The measurement of specific IgE appears not to be a useful adjunct in the diagnosis of CMPSE in Malaysian children.

    Serum immunoglobulin G, A, M, D and E levels were determined in the forest-dwelling Orang Asli of age group 8 to 64 years. The levels are higher than observed for urban Malaysians and comparable to levels reported for populations residing in the tropics. There was no significant difference in serum levels of all the immunoglobulins studied in both sexes. The elevated serum immunoglobulins levels are discussed in terms of the nature of the immune defence developed in the Orang Asli to contend with the many parasites prevalent in their environment.

    The diverse clinical syndromes characterized by asthmatic symptoms, transient pulmonary infiltrates, and eosinophilia have tended to obscure the specific association of one such entity with filarial infections. Serum IgE levels were determined before and after therapy in a group of well-characterized patients with tropical eosinophilia (TE), studied earlier in Singapore. The mean serum IgE level in 14 cases before treatment with diethylcarbamazine was 2,355 ng. per milliliter, with a trend but statistically nonsignificant decrease in levels to 600-1,000 ng. occurring 8 to 12 weeks after therapy. Leukocyte and eosinophil counts showed a rapid reduction after treatment, and although mean complement-fixing (cf) titers to Dirofilarial antigen tended to decrease, they were not significantly reduced until 5 to 6 weeks. The historical development of evidence supporting the filarial etiology of TE was reviewed. Many basic questions engendered by the clinical syndrome of tropical eosinophilia make it an excellent model for study of the immunopathology of parasitic infections.

    BACKGROUND: Specific immunoglobulin E (sIgE) within the nasal airway is likely to be the most ideal marker of allergic status, but little is known of the normative values in asymptomatic patients and those with rhinitis.

    OBJECTIVE: The aim of this study was to assess the diagnostic characteristics of inferior turbinate tissue biopsy sIgE in asymptomatic and rhinitic patients.

    METHODS: A diagnostic cross-sectional study was undertaken, involving patients who underwent inferior turbinate surgery with or without other surgical interventions. Inferior turbinate tissue biopsy was performed during surgery and was assessed for allergen sIgE (dust mite, grass [temperate or subtropical], and animal epithelium) using an automated immunoassay. Tissue sIgE was assessed among asymptomatic patients and those with nasal symptoms. Data were presented as median (interquartile range). A receiver operating curve was used to predict the diagnostic utility of turbinate tissue sIgE in determining allergic rhinitis.

    RESULTS: A total of 160 patients (41.89 ± 14.65 years, 36.9% females) were included. The median tissue sIgE concentration among the asymptomatic nonatopic group of patients was 0.09 (0.08-0.10) kUA/L and tissue sIgE > 0.10 kUA/L was determined as a positive threshold. Inferior turbinate tissue sIgE was shown to be a predictive test for allergic rhinitis (area under curve: 0.87, 95% confidence interval: 0.84-0.90) with 90% sensitivity and 89% negative predictive value.

    CONCLUSION: Inferior turbinate tissue biopsy sIgE is a sensitive tool to predict allergic rhinitis. The threshold value of 0.1 kUA/L corresponded well with the asymptomatic nonatopic group of patients. This method detects sIgE in the nasal mucosa and may be a useful test for allergic rhinitis in future research.

    Three patients presenting with parotid, submandibular, and/or lymph node masses were subjected to fine-needle aspiration cytology. Smears showed dissociated and clustered endothelial cells, eosinophils, lymphocytes, and Warthin Finkeldey giant cells. In two cases a diagnosis of Kimura's disease was suggested from the FNA cytologic smears. In the third case the presence of mononucleate cells with prominent nucleoli led to a suspicion of Hodgkin's disease. Excision biopsy and histopathologic study established a diagnosis of Kimura's disease in all three cases.

    The present study was conducted with the aim to investigate the immuno-modulatory and histological stabilization effects of nanocarrier-based transcutaneous co-delivery of hydrocortisone (HC) and hydroxytyrosol (HT). In this investigation, the clinical and pharmacological efficacies of nanoparticle (NP)-based formulation to alleviate 2,4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis (AD) was explored by using an NC/Nga mouse model. Ex vivo visual examination of AD induction in experimental mice indicated remarkable control of NP-based formulations in reducing pathological severity of AD-like skin lesions. Therapeutic effectiveness of NP-based formulations was also evaluated by comparing skin thickness of AD-induced NP-treated mice (456±27 µm) with that of atopic mice (916±37 µm). Analysis of the immuno-spectrum of AD also revealed the dominance of NP-based formulations in restraining immunoglobulin-E (IgE), histamine, prostaglandin-E2 (PGE2), vascular endothelial growth factor-α (VEGF-α), and T-helper cells (TH1/TH2) producing cytokines in serum and skin biopsies of tested mice. These anti-AD data were further supported by histological findings that revealed alleviated pathological features, including collagen fiber deposition, fibroblasts infiltration, and fragmentation of elastic fibers in experimental mice. Thus, NP-mediated transcutaneous co-delivery of HC and HT can be considered as a promising therapy for managing immunological and histological spectra associated with AD.
