为了研究用化妆品进行斑贴试验时所需浓度,探讨用患者使用过的可疑化妆品进行斑贴试验在诊断化妆品皮炎中的应用价值,将各种化妆品以不同浓度对35例健康者,38例非接触性皮炎湿疹类患者进行斑贴试验。然后用患者各自的可疑致敏化妆品对62例化妆品皮炎患者进行斑贴试验。结果:初步认为护肤类膏剂、唇膏、护发类发乳、头油、摩丝等类产品可用原物进行斑贴试验,染发剂、清洁类香皂、护发类油用2%,清洁类香波用2%和5%,冷烫精、指甲油、香水用5%或10%。可疑化妆品斑贴试验的阳性率为95.16%。本研究表明:用可疑化妆品作斑贴试验时,不同类型的产品,其斑贴试验浓度并不相同,用患者的可疑化妆品进行斑贴试验是诊断化妆品皮炎的重要手段。这项研究为进一步研究我国化妆品皮炎标准筛选系列抗原提供了必要资料。 相似文献

2-day (2-D) closed patch tests are often used in daily clinical practice and useful for evaluating the cause of allergic contact dermatitis. However, even when 2-D closed patch tests at appropriate concentrations are performed for suspected allergic contact dermatitis based on clinical findings, positive reactions are not always obtained. Therefore, although the use of the allergen again induces similar symptoms, a definite diagnosis cannot be made in some cases. We report a case of allergic contact dermatitis due to phenylephrine hydrochloride in eyedrops, with an unusual patch test reaction. Although the results of the routine 2-D closed patch test were negative, a definite diagnosis could be made by closed scratch-patch test. In addition, long-lasting allergic patch test reactions were observed at the positive scratch-patch test site for about 3 months. We speculated that these unusual results on patch testing in our case were associated with the degree of percutaneous absorption of causative agents. Therefore, even when 2-D closed patch tests are negative, scratch-patch tests may be indicated for patients in whom clinical symptoms continue strongly to suggest contact dermatitis. 相似文献

Putative allergens in, clinical manifestations of, and patch tests with traditional Chinese medicinal materials (CMM) causing contact dermatitis (CD) were studied. 14 patients with CMM CD and 351 controls were patch tested with the standard series of allergens of Beijing Medical University and the suspected drug, as is. It was found that most CMM CD was caused by the CMM frequently used topically for analgesic and anti-inflammatory effect. All patients patch tested with the suspected drug gave positive results. Some patients also reacted to fragrance mix. Colophony, rubber mix and ammoniated mercury. The positively rates of fragrance mix and colophony in CMM CD patients were significantly higher than in controls (55.6% versus 16.5% for fragrance mix, X 2 = 11. 86, P < 0.01; and 55.6% versus 5.1% for colophony, X 2 = 29.35. P < 0.01), while not those of rubber mix and ammoniated mercury. Results indicated that the topical analgesic and anti-inflammatory CMM, especially those containing fragrance, may cause contact sensitization. Clinical findings in CMM CD included cutaneous irritation, allergic contact dermatitis. immediate contact reactions and systemic contact dermatitis. CMM CD can he diagnosed by patch testing the putative drug, as is. 相似文献

As many new cosmetic products are introduced into the market, attention must be given to contact dermatitis, which is commonly caused by cosmetics. We investigate the prevalence of preservative allergy in 584 patients with suspected cosmetic contact dermatitis at 11 different hospitals. From January 2010 to March 2011, 584 patients at 11 hospital dermatology departments presented with cosmetic contact dermatitis symptoms. These patients were patch-tested for preservative allergens. An irritancy patch test performed on 30 control subjects using allergens of various concentrations showed high irritancy rates. Preservative hypersensitivity was detected in 41.1% of patients. Allergens with the highest positive test rates were benzalkonium chloride (12.1%), thimerosal (9.9%) and methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) (5.5%). Benzalkonium chloride and chlorphenesin had the highest irritancy rate based on an irritancy patch test performed using various concentrations. Seven of 30 normal subjects had a positive irritant patch reading with 0.1% benzalkonium chloride and eight of 30 normal subjects had a positive irritant patch reading at 4 days with 0.5% chlorphenesin in petrolatum. Although benzalkonium chloride was highly positive for skin reactions in our study, most reactions were probably irritation. MCI/MI and thimerosal showed highly positive allergy reactions in our study. The optimum concentration of chlorphenesin to avoid skin reactions is less than 0.5%. 相似文献
