BACKGROUND: The number of available reports regarding the influence of ethnicity on clinical features of allergic rhinitis (AR), especially disease severity in tropical climates, is limited. We aimed to compare clinical parameters and disease severity in AR patients of different ethnicities.

METHODS: Malay, Chinese, and Indian AR patients (n = 138) with confirmed sensitivity to Dermatophagoides pteronyssinus, Dematophagoides farinae, and Blomia tropicalis were tested for mite-specific immunoglobulin E (sIgE) levels. A detailed questionnaire was used to collect data on nasal symptom score (NSS), ocular symptom score (OSS), sum of symptoms score (SSS), quality of life score (QLS), symptomatic control score (SCS), and total sum of scores (TSS) and correlate the derived data with patients' demography, mite-polysensitivity, and sIgE levels.

RESULTS: AR-related symptoms were most severe in Malays and least in Chinese (p < 0.01). Age (r = 0.516 to 0.673, p < 0.05) and duration of AR (r = 0.635 to 0.726, p < 0.01) correlated positively with severity domains (NSS, SSS, QLS, and TSS) in Chinese. Duration of concurrent allergies was highest in Malays (p < 0.05). Polysensitivity predicted increased sIgE levels in Malays (r = 0.464 to 0.551, p < 0.01) and Indians (r = 0.541 to 0.645, p < 0.05) but affected NSS, SSS, and TSS only in Indians (r = 0.216 to 0.376, p < 0.05). sIgE levels were lowest among Chinese but correlated strongly with NSS, OSS, SSS, and TSS (r = 0408 to 0.898, p < 0.05).

CONCLUSION: Clinical parameters in AR may be influenced by race. Symptoms were most severe among Malays but did not correlate with other variables examined. Although Indian ethnicity did not impact disease severity, duration of concurrent allergies and mite-polysensitivity was associated with more severe disease. Age, duration of disease, and sIgE levels may be useful indicators of disease severity in Chinese.

Specific IgE in the identification of allergens in allergic rhinitis Malaysian patients

Choon-Kook S, Teck-Soong SL

Asian Pac J Allergy Immunol, 1995 Jun;13(1):23-7.

PMID: 7488340

The specific serum IgE levels to 20 allergens were determined by enzyme immunoassay in 90 Malaysian patients with allergic rhinitis. Ninety-two percent of patients had elevated IgE to at least 1 of the allergens. The housedust mites D. pteronyssinus and D. farinae were the major allergens, elevated IgE to either allergen being present in 86% of the patients. Prick skin tests were carried out in some of the patients, housedust mites, cat fur, dog hair and shrimp were the allergens used. Close correspondence was found between IgE and prick skin tests to the mites.

Fulltext Early gut colonization by Bifidobacterium breve and B. catenulatum differentially modulates eczema risk in children at high risk of developing allergic disease

Ismail IH, Boyle RJ, Licciardi PV, Oppedisano F, Lahtinen S, Robins-Browne RM, et al.

Pediatr Allergy Immunol, 2016 12;27(8):838-846.

PMID: 27590263 DOI: 10.1111/pai.12646

BACKGROUND: An altered compositional signature and reduced diversity of early gut microbiota are linked to development of allergic disease. We investigated the relationship between dominant Bifidobacterium species during the early post-natal period and subsequent development of allergic disease in the first year of life.

METHODS: Faecal samples were collected at age 1 week, 1 month and 3 months from 117 infants at high risk of allergic disease. Bifidobacterium species were analysed by quantitative PCR and terminal restriction fragment length polymorphism. Infants were examined at 3, 6 and 12 months, and skin prick test was performed at 12 months. Eczema was diagnosed according to the UK Working Party criteria.

RESULTS: The presence of B. catenulatum at 3 months was associated with a higher risk of developing eczema (ORadj = 4.5; 95% CI: 1.56-13.05, padj = 0.005). Infants colonized with B. breve at 1 week (ORadj = 0.29; 95% CI: 0.09-0.95, padj = 0.04) and 3 months (ORadj = 0.15; 95% CI: 0.05-0.44, padj = 0.00001) had a reduced risk of developing eczema. Furthermore, the presence of B. breve at 3 months was associated with a lower risk of atopic sensitization at 12 months (ORadj = 0.38; 95% CI: 0.15-0.98, padj = 0.05). B. breve colonization patterns were influenced by maternal allergic status, household pets and number of siblings.

CONCLUSIONS: Temporal variations in Bifidobacterium colonization patterns early in life are associated with later development of eczema and/or atopic sensitization in infants at high risk of allergic disease. Modulation of the early microbiota may provide a means to prevent eczema in high-risk infants.

Fulltext Lupus band test in systemic lupus erythematosus

Gangaram HB, Kong NCT, Phang KS, Suraiya H

Med J Malaysia, 2004 Dec;59(5):638-48.

PMID: 15889567

The usefulness of the direct immunofluorescent antibody technique--lupus band test--for the diagnosis of systemic lupus erythematosus (SLE) has been well established. The aims of the study were to determine the prevalence of the LBT at various sites of the skin in a cross section of patients with SLE and its correlation with disease activity. The LBT was demonstrated in 64% of skin lesions, 63% in non-lesional sun-exposed (NLSE) skin and 25% in non-lesional sun-protected (NLSP) skin. The prevalence of the LBT in lesional and NLSE groups was significantly different from the NLSP group (p = 0.03 and 0.005 respectively). There was a significant correlation between the presence of a positive LBT in NLSE skin with the presence of the LE cell phenomenon (p = 0.04) and anti - ds DNA antibody (0.02). In addition, there was a significant correlation between IgG LBT in the NLSE skin with serum hypocomplementaemia (p = 0.03) and anti - ds DNA antibody (p = 0.04). Other than these, no significant correlation was detected between the LBT from the 3 sites with overall clinical activity, renal disease, active skin lesions, or other laboratory indices of activity. These findings suggest that the LBT is mainly indicated as a diagnostic tool and has little role in assessing disease activity.

Fulltext Development of ELISA for diagnosis of allergy to Dermatophagoides farinae

Ho TM, Radha K, Shahnaz M, Singaram SP

Med J Malaysia, 1993 Sep;48(3):308-12.

PMID: 8183144

An indirect enzyme linked immunosorbent assay (ELISA) was developed for the diagnosis of allergy to a house dust mite, Dermatophagoides farinae. The efficacy of the ELISA was then evaluated against a prick test using a commercial allergen. Eighty five suspected allergic rhinitis patients from the Otorhinolaryngology Department, Kuala Lumpur General Hospital, were tested with the ELISA and prick test. Prick test and ELISA results were positive in 84.7% and 80.0% of the patients respectively. The ELISA was found to have 87.5% sensitivity, 61.5% specificity, 92.6% positive predictive value, 47.1% negative predictive value, 7.4% false positive and 52.9% false negative. There was total agreement between the prick test and ELISA for prick test grades of 3+ and 4+. It is concluded that the ELISA is a useful assay for detection of individuals who are highly sensitive to D. farinae.

PMID: 26668407 DOI: 10.11622/smedj.2015171

The prevalence of perceived food allergies exceeds that of true food allergies. Unnecessary food avoidance may increase parental and patient anxiety, reduce quality of life and increase the risk of nutritional deficiency. An oral food challenge (OFC) can provide an objective measure regarding the presence or absence of food allergies in a child. This study reviews the indications for and outcomes of OFCs performed on children.

Asthmatic patients constitute up to 5% of admissions to medical wards in our area. Analysis of 1099 adult asthmatic admissions over a 3-year period showed that Malays composed 31% of patients (expected 23%), Indians composed 36% (expected 31%) and Chinese only 32% (expected 46%). There was a reduced prevalence of asthma in the Chinese (P less than 0.001). Male asthmatic admissions showed a non-seasonal cyclic variation (P less than 0.01) with an increasing trend in the number of admissions (P less than 0.02). The proportion of male to female asthmatic admissions did not differ. In a sample of 50 asthmatic patients, studied in detail, the mean age of onset was 33.3 years (range 6-74) while only 14% of subjects had onset of asthma before the age of 10 years. Although the clinical features of these patients differ from those of Caucasian asthmatics, skin prick tests and other features suggest that the majority of our patients suffer from extrinsic atopic asthma.

Crab meat is a valuable source of proteins and functional lipids and it is widely consumed worldwide. However, the prevalence of crab allergy has increased over the past few years. In order to understand crab allergy better, it is necessary to identify crab allergens. The aim of the present study was to compare the IgE-binding proteins of raw and cooked extracts of mud crab (Scylla serrata). Raw and cooked extracts of the mud crab were prepared. Protein profiles and IgE reactivity patterns were identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) followed by immunoblotting using sera from 21 skin prick test (SPT) positive patients. In SDS-PAGE, 20 protein bands (12 to 250 kDa) were observed in the raw extract while the cooked extract demonstrated fewer bands. Protein bands between 40 to 250 kDa were sensitive to heat denaturation and no longer observed in the cooked extract. In immunoblotting experiments, raw and cooked extracts demonstrated 11 and 4 IgE-binding proteins, respectively, with molecular weights of between 23 and 250 kDa. A heat-resistant 36 kDa protein, corresponding to crab tropomyosin was identified as the major allergen of both extracts. In addition, a 41 kDa heat-sensitive protein believed to be arginine kinase was shown to be a major allergen of the raw extract. Other minor allergens were also observed at various molecular weights.

Fulltext Atopic sensitization of children with rhinitis in Malaysia

Gendeh BS, Mujahid SH, Murad S, Rizal M

Med J Malaysia, 2004 Oct;59(4):522-9.

PMID: 15779586 MyJurnal

Atopy is defined as the genetic propensity to develop immunoglobulin E antibodies in response to exposure to allergens and assessed by skin prick test (SPT) responses to common allergens, which may contribute to the development of the clinical disorders (phenotype). Although it is generally agreed that atopy is an important risk factor for allergic diseases such as asthma, rhinitis, and eczema, the extent to which atopy accounts for these diseases is controversial. One hundred forty one children (up to 12 years) were skin prick tested to evaluate 16 foods common to the Malaysian diet and 4 common aeroallergens. Eighty-five percent of patients had positive SPT reactivity. The most commonly implicated aeroallergen and food allergen was house dust mite (HDM) and Prawn. Seventy percent had positive SPT reactivity results to HDM and 24.8% to prawns. Fifty five percent were positive to more than one allergen and 17.7% positive to single aeroallergen. The prevalence of atopy in children with history of eczema was 90%. The incidence of HDM and food allergy especially crabs and prawns, is significantly greater in Malaysian Children with rhinitis symptoms.

Fulltext The Kveim test in lepromatous and tuberculoid leprosy

Pearson JMH, Pettit JHS, Siltzbach LE, Ridley DS, Hart PD, Rees RJ

Int. J. Lepr. Other Mycobact. Dis., 1969;37(4):372-81.

PMID: 5394258

Kveim tests using a validated material have been undertaken in Malaysia on 39 patients (32 Chinese; 4 Malay and 3 Aboriginal) with lepromatous or tuberculoid leprosy. All the patients had been treated for leprosy, most for two or more years. The tests were read microscopically. Of the 21 lepromatous patients one gave a weak positive and two an equivocal Kveim test whereas four of the nine tuberculoid patients gave equivocal or weak Kveim positivity. Only the tuberculoid form elicits a higher proportion of granulomas than might be expected in a comparable normal population. Of nine patients (8 lepromatous; 1 tuberculoid ) who failed to sensitize well to tuberculin
following two BCG vaccinations, two gave equivocal Kveim tests similar in appearance to those in the other groups.

Nasopharyngeal carcinoma and nasal allergy: any correlation?

Prepageran N, Lingham OR, Krishnan G, Jalaludin MA, Raman R

Ear Nose Throat J, 2003 Jun;82(6):438-40.

PMID: 12861869

Although it has been observed that nasal allergy is rarely seen in patients who have nasopharyngeal carcinoma, to our knowledge, no actual study of such a lack of association has been previously reported. To fill this void, we conducted a pilot study to investigate any such inverse relationship. We conducted skin-prick allergen tests on 22 patients with newly diagnosed but not-yet-treated nasopharyngeal carcinoma. Combining these test results with findings on the history and clinical examination, we concluded that only one of the 22 cancer patients (4.5%) had allergic rhinitis. Our study also confirmed the validity of using findings on the history, clinical examination, and skin-prick testing as a reliable means of diagnosing allergic rhinitis.

Three groups of people with different clinical histories and manifestations to house dust were skin tested with Dermatophagoides pteronyssinus extracts. The results showed close correlation between positive skin tests and clinical sensitivity to dust. The correlation was not, however, perfect and, although D. pteronyssinus is a major factor in house dust allergy, it does not appear to be the sole antigen involved.

Low prevalence of latex sensitivity in South African spina bifida children in Cape Town

Johar A, Lim DL, Arif SA, Hawarden D, Toit GD, Weinberg EG, et al.

Pediatr Allergy Immunol, 2005 Mar;16(2):165-70.

PMID: 15787875

Spina bifida children have a high prevalence of latex allergy in studies reported from Europe and the USA. This study investigated the prevalence of latex allergy in a cohort of 24 spina bifida children at the Red Cross Children's Hospital from Cape Town, South Africa. The children were investigated using a detailed questionnaire, skin prick tests (ALK-Abello), ImmunoCap RASTs, Western blotting and ELISA, using the purified latex proteins Hev b1 and Hev b3 and whole latex preparation. A low overall prevalence of latex sensitization of 16.7% was found in the children. Children who were sensitive reacted to water insoluble to Hev b1 and Hev b3 proteins. The low prevalence of latex sensitization in the South African children may not be entirely explained by stringent latex avoidance. The children were from a low socioeconomic social status and 'hygiene' and other factors should be considered.
