Psoriasis has been considered an autoimmune, T cell-mediated disorder in which adaptive immune responses predominate over those of non-antigen-specific innate immunity. To test this hypothesis, we profiled the transcriptome of psoriatic tissue and compared the data with that from cultured human keratinocytes exposed to the proinflammatory cytokine(More)
Genome-wide association studies (GWASs) have primarily focused on marginal effects for individual markers and have incorporated external functional information only after identifying robust statistical associations. We applied a new approach combining the genetics of gene expression and functional classification of genes to the GWAS of basal cell carcinoma(More)
Atopic dermatitis (AD) results from strong genetic and environmental interactions. AD shows genetic linkage to Chromosome 1q21. This region contains the epidermal differentiation complex (EDC), which consists of genes that form essential components of epidermal surfaces. Filaggrin (FLG) is one of these. Mutations in FLG/(R501X and 2282del4) are reported to(More)
In an open, multicentre evaluation carried out in Brazil, Canada and South Africa we have demonstrated that fluconazole 8 mg kg-1 once weekly is effective in tinea capitis caused by Trichophyton and Microsporum species. There were 61 children, aged (mean +/- SE) 5.0 +/- 0.3 years; weight (mean +/- 5.6) 20.0 +/- 0.9 kg; 41 males, 20 females; one Asian, 57(More)
Atopic dermatitis (AD) is a chronic itching (pruritic) skin disease. It results from a complex interplay between strong genetic and environmental factors. Genome screens of families with AD have implicated chromosomal regions that overlap with other skin diseases and with inflammatory and autoimmune diseases. These, together with candidate gene studies,(More)
Gene expression levels can be an important link DNA between variation and phenotypic manifestations. Our previous map of global gene expression, based on ~400K single nucleotide polymorphisms (SNPs) and 50K transcripts in 400 sib pairs from the MRCA family panel, has been widely used to interpret the results of genome-wide association studies (GWASs). Here,(More)
BACKGROUND Pemphigus is an autoimmune disease characterized by intraepidermal blistering. We describe the demography, prevalence, clinical features, response to treatment, and human leukocyte antigen (HLA) characteristics of pemphigus in Kwa-Zulu Natal, South Africa. METHODS All patients with pemphigus were prospectively recruited over 12 years from(More)
Tinea capitis is a relatively common fungal infection of childhood. Griseofulvin has been the mainstay of management. However, newer oral antifungal agents are being used more frequently. A multicenter, prospective, randomized, single-blinded, non-industry-sponsored study was conducted in centers in Canada and South Africa to determine the relative efficacy(More)
Atopic dermatitis (AD) is the most common dermatological disease of childhood. Many children with AD have asthma and AD shares regions of genetic linkage with psoriasis, another chronic inflammatory skin disease. We present here a genome-wide association study (GWAS) of childhood-onset AD in 1563 European cases with known asthma status and 4054 European(More)
UNLABELLED Background Erythroderma has protean underlying causes. There have been isolated case reports suggesting an association between erythroderma and the human immunodeficiency virus (HIV). OBJECTIVE To describe and characterize further the prevalence, etiology, and metabolic sequelae of erythroderma in HIV positive and negative patients. In a subset(More)
