BACKGROUND: Hand eczema is a common chronic and relapsing skin disease with various clinical features. Hand eczema aetiology can be allergic contact dermatitis (ACD), irritant contact dermatitis (ICD), atopic dermatitis (AD) and unknown or combination causes. If the causative agents are not detected treatment of hand eczema will be a failure. A patch test can be useful to detect causative agents in suspected allergic contact hand eczema. Then patients will avoid contacting them. This results in the improvement of hand eczema. In Vietnam, patch test has not been used before, so we conduct this study. AIM: To identify causative allergens by using patch test with 28 standard allergens in consecutive patients. METHODS: A group of 300 HE patients from the National Hospital of Dermatology and Venereology (NHDV) in Vietnam were enrolled in this study. They were divided into 4 groups-ACD, ICD, AD and unknown aetiology. The patient was patch tested with 28 standard allergens to identify the causative agents. RESULTS: Among the 300 HE enrolled patients, ACD accounted for 72.7%, AD and ICD had the same rate of 12.7%. 39.3% of the patients had a positive patch test. Reaction to nickel sulfate was the most common (10.3%), followed by potassium dichromate (9.7%), cobalt (4%) and fragrance mix (3.1%). About one-third of the cases had relevant clinical reactions correlated with the contact agents and clinical history. Males reacted to cement, thiuram mix and formaldehyde more than females, while females reacted to a nickel more than males. CONCLUSIONS: Hand eczema has variable clinical features and diverse aetiology. ACD is an important cause of hand eczema that can be managed with a patch test to detect causative allergens. Nearly 40% of HE cases had positive patch test. Relevant patch test reactions were seen in one-third of the patients. We propose using patch test detect causative agents in suspected allergic contact hand eczema. Then patients will avoid contacting them. This results in the improvement of hand eczema.

Objectives: Chronic spontaneous urticaria (CSU) is defined as short lived (< 24h) wheals occurring spontaneously without any triggering factors, daily or almost daily for at least 6 weeks. Though CSU is mainly a Type 1 hypersensitivity reaction, earlier studies suggested contact allergy may have some role to play an important role in the etiopathogenesis of CSU. The objective of the study is to find out the relevance of patch test in the etiopathogenesis of and its correlation with serum IgE level. Materials and Methods: Thirty-one patients of CSU were thoroughly evaluated for clinical and laboratory parameters. We conducted patch testing with Indian Standard Series (ISS) in all of them and tried to find out the relevance of every positive reaction. Relevant positive cases were asked to avoid exposure for 2 months and were maintained only in breakthrough antihistamines. Furthermore, correlation of positive patch test reaction with high IgE and eosinophil count were studied. Results: Seventeen (55%) cases came positive for patch test. Potassium dichromate, lanolin, benzocaine, and fragrance mix were the most common offenders. Patients with very high IgE count had patch test positivity with multiple allergens. Seven of the fifteen patients who had relevant positive patch results could be followed up to remission; three were lost to follow-up. Conclusion: Patch test with ISS may give important clue to in a subset of patients of CSU and thus may be considered an important part of routine investigations of CSU.

Background and Objective. The pattern of contact sensitization among patients with chronic leg ulcers depends on the local practice of wound treatment along with demographic and clinical confounders. The study was aimed at revealing the associations between chronic leg ulcers and contact sensitization. Material and Methods. Between 2006 and 2008, 35 patients with chronic leg ulcers and surrounding dermatitis and 59 patients with contact dermatitis of the lower leg or foot were prospectively recruited at the Department of Skin and Venereal Diseases, Lithuanian University of Health Sciences. Demographic and clinical data were collected in accordance with the “minimal data set” of the European Surveillance System on Contact Allergy. Patch testing was performed with the allergens of the European baseline series. Results. At least one positive patch test reaction was found in 28 (80%) of the patients with chronic leg ulcers and in 24 (41%) of the patients with dermatitis of the lower leg or foot (P<0.001). Sensitization to some of the most common allergens, namely colophony, Myroxylon pereirae resin, and methyldibromo glutaronitrile, was prevalent in both the groups of patients, whereas sensitization to benzocaine, p-phenylenediamine, and lanolin alcohol was associated with the presence of chronic leg ulcers. Benzocaine was found to be the leading allergen among patients with chronic leg ulcers (positive patch test reactions in 34.4% of the patients). Conclusions. Contact sensitization to benzocaine, p-phenylenediamine, and lanolin was found to be associated with the presence of chronic leg ulcers.

Objectives: The objective of the study was to identify the allergens showing positive patch test reaction (using Indian standard battery of allergens) in cement workers with clinically diagnosed allergic contact dermatitis (CD) to cement attending a tertiary referral center. Materials and Methods: We included cement workers with clinically diagnosed allergic CD to cement who attended the dermatology outpatient clinic of our tertiary referral center from January 2013 to December 2013. We did patch testing in all the cases ( after subsidence of active dermatitis) with Indian standard battery of patch test allergens and documented the allergens that showed a positive reaction. Results: Forty-seven (94%) of the 50 study participants showed a positive reaction to one or more of the allergens. The most common allergen that showed a positive reaction was potassium dichromate (43/50, 86%). Twenty-five patients (50%) showed positive reactions to more than 1 allergen. Four patients (8%) showed positive reactions only to allergens that were not seen in cement. Limitations: Small sample size and lack of information on clinical response of dermatitis to avoidance of identified allergen were the major limitations. Conclusion: Twenty-five (50%) patients showing positive reactions to more than 1 allergen tested and 4 (8%) showing positive patch test reaction to none of the allergens in cement (but to other allergens) highlight the role of patch testing in identifying the probable allergens in patients with clinically diagnosed allergic CD to cement.
