          Abstract

          Minocycline is an antibiotic of tetracycline derivatives that is commonly used in the treatment of moderate to severe acne vulgaris. It has been reported to cause rare adverse events from mild cutaneous eruption to severe forms including drug-induced lupus, serum sickness-like reaction, and hypersensitivity reactions, etc. The risks of adverse events attributed to minocycline have not been ascertained reliably and there are concerns about the safety of minocycline which could possibly result in life-threatening events such as the Stevens-Johnson syndrome. Here we demonstrate an unusual case of Stevens-Johnson syndrome in conjunction with bilateral parotitis after the intake of minocycline in a Korean boy suggesting discreet use of the drug.

          Clinical classification of cases of toxic epidermal necrolysis, Stevens-Johnson syndrome, and erythema multiforme.

          To conduct a prospective case-control study about causative factors of severe bullous erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis, we needed to define criteria for classifying the cases and standardize the collection of data so that cases could be reliably diagnosed according to this classification. Based on review of case histories and photographs of patients, a group of experts proposed a classification based on the pattern of erythema multiforme-like lesions (categorized as typical targets, raised or flat atypical targets, and purpuric macules) and on the extent of epidermal detachment. An atlas illustrating this classification that included photographs and schematic drawings was developed. We compared the evaluations of 28 cases by four nonphysicians relying on the atlas with the evaluations of the same cases by five experts not using the atlas to determine the usefulness of this atlas for classifying cases according to our nosologic schema. The following consensus classification in five categories was proposed: bullous erythema multiforme, detachment below 10% of the body surface area plus localized "typical targets" or "raised atypical targets"; Stevens-Johnson syndrome, detachment below 10% of the body surface area plus widespread erythematous or purpuric macules or flat atypical targets; overlap Stevens-Johnson syndrome-toxic epidermal necrolysis, detachment between 10% and 30% of the body surface area plus widespread purpuric macules or flat atypical targets; toxic epidermal necrolysis with spots, detachment above 30% of the body surface area plus widespread purpuric macules or flat atypical targets; and toxic epidermal necrolysis without spots, detachment above 10% of the body surface area with large epidermal sheets and without any purpuric macule or target. Using the atlas, the nonexperts showed excellent agreement with the experts. This study suggests that an illustrated atlas is a useful tool for standardizing the diagnosis of acute severe bullous disorders that are attributed to drugs or infectious agents. Whether the five categories proposed represent distinct etiopathologic entities will require further epidemiologic and laboratory investigations.

            Clinical heterogeneity of drug hypersensitivity.

            Skin is the most frequent target of drug reactions that are reported, may be because they are easily detected. Most (probably more than 90%) are related to drug hypersensitivity, i.e. an individually tailored, unexpected effect mediated by a drug specific activation of the immune response. The clinical presentation of "drug eruptions" is highly variable, from the most common transient and benign erythema that occurs 6-9 days after the introduction of a new drug in 1 to 3 % of users to the most severe forms, that fortunately affect less than 1/10,000 users. Even though there are some overlapping or unclassifiable cases, it is important for clinicians to recognize and categorize severe cutaneous adverse reactions/SCAR (bullous fixed drug eruptions/bFDE, acute generalized exanthematous pustulosis/AGEP, drug reaction with eosinophilia and systemic symptoms/DRESS, Stevens-Johnson syndrome/SJS, toxic epidermal necrolysis/TEN). First they must suspect rapidly that an unusual eruption with high fever and severe constitutional symptoms is caused by a medication and not by an infection. Second they have to look for involvement of organs that differ according to the type of reaction. Third they can determine a prognosis, the mortality rate being virtually 0 for bFDE, 5% for AGEP, 10% for "hypersensitivity syndrome"/DRESS and 25% for SJS or TEN. In addition if some medications are "usual suspects" for all types (e.g. anticonvulsants), some other are more specific of a given pattern (pristinamycine, hydroxychloroquine, diltiazem for AGEP, minocycline for DRESS, anti-infectious sulfonamides, allopurinol for epidermal necrolysis). The "phenotypic" diversity of the final expression drug reactions can be explained by the engagement of a variety of cytokines and inflammatory cells and by regulatory mechanisms. For example, memory cytotoxic T-Cells are key effectors in both localized blisters of bFDE and in extensive blisters of epidermal necrolysis.

              Correlations between clinical patterns and causes of erythema multiforme majus, Stevens-Johnson syndrome, and toxic epidermal necrolysis: results of an international prospective study.

              It was proposed that Stevens-Johnson syndrome and toxic epidermal necrolysis differed from erythema multiforme majus by the pattern and localization of skin lesions. To evaluate the validity of this clinical separation. Case-control study. Active survey from 1989 to 1995 of 1800 hospital departments in Europe. A total of 552 patients and 1720 control subjects. Cases were sorted into 5 groups (erythema multiforme majus, Stevens-Johnson syndrome, Stevens-Johnson syndrome-toxic epidermal necrolysis overlap, toxic epidermal necrolysis, and unclassified erythema multiforme majus or Stevens-Johnson syndrome) by experts blinded as to exposure to drugs and other factors. Etiologic fractions for herpes and drugs obtained from case-control analyses were compared between these groups. Erythema multiforme majus significantly differed from Stevens-Johnson syndrome, overlap, and toxic epidermal necrolysis by occurrence in younger males, frequent recurrences, less fever, milder mucosal lesions, and lack of association with collagen vascular diseases, human immunodeficiency virus infection, or cancer. Recent or recurrent herpes was the principal risk factor for erythema multiforme majus (etiologic fractions of 29% and 17%, respectively) and had a role in Stevens-Johnson syndrome (etiologic fractions of 6% and 10%) but not in overlap cases or toxic epidermal necrolysis. Drugs had higher etiologic fractions for Stevens-Johnson syndrome, overlap, or toxic epidermal necrolysis (64%-66%) than for erythema multiforme majus (18%). Unclassified cases mostly behaved clinically like erythema multiforme. This large prospective study confirmed that erythema multiforme majus differs from Stevens-Johnson syndrome and toxic epidermal necrolysis not only in severity but also in several demographic characteristics and causes.
