RESUMO

Lifestyle treatments can be defined as those which may have in impact on quality of life but do not affect health outcomes. Particular treatment options may be preferred by patients because they are for example, easier to use, take up less time or taste better. The impact on adherence needs to be considered. Treatment options that promote greater adherence to therapy are likely to be more efficacious and so are not, by definition, lifestyle treatments. The NHS is facing unprecedented financial pressure and resources are limited. When lifestyle treatments are more expensive than standard therapy, they should not be funded by the NHS.

RESUMO

An 8-year-old boy presented with ulcers on the lip and limbs, scattered pustules, fever, and general malaise. Further investigation revealed splenic and pulmonary lesions. A diagnosis of pyoderma gangrenosum with splenic and pulmonary involvement was made. The authors have not found a previous report of pediatric pyoderma with splenic involvement in the literature.

RESUMO

BACKGROUND: Trachoma, a chronic keratoconjunctivitis caused by Chlamydia trachomatis, is the world's commonest infectious cause of blindness. Blindness is due to progressive scarring of the conjunctiva (trachomatous scarring) leading to in-turning of eyelashes (trichiasis) and corneal opacification. We evaluated the contribution of genetic variation across the chemokine and cytokine clusters in chromosomes 4q and 5q31 respectively to risk of scarring trachoma and trichiasis in a large case-control association study in a Gambian population. METHODS: Linkage disequilibrium (LD) mapping was used to investigate risk effects across the 4q and 5q31 cytokine clusters in relation to the risk of scarring sequelae of ocular Ct infection. Disease association and epistatic effects were assessed in a population based study of 651 case-control pairs by conditional logistic regression (CLR) analyses. RESULTS: LD mapping suggested that genetic effects on risk within these regions mapped to the pro-inflammatory innate immune genes interleukin 8 (IL8) and granulocyte-macrophage colony stimulatory factor (CSF2) loci. The IL8-251 rare allele (IL8-251 TT) was associated with protection from scarring trachoma (OR = 0.29 p = 0.027). The intronic CSF2_27348 A allele in chromosome 5q31 was associated with dose dependent protection from trichiasis, with each copy of the allele reducing risk by 37% (p = 0.005). There was evidence of epistasis, with effects at IL8 and CSF2 loci interacting with those previously reported at the MMP9 locus, a gene acting downstream to IL8 and CSF2 in the inflammatory cascade. CONCLUSION: innate immune response SNP-haplotypes are linked to ocular Ct sequelae. This work illustrates the first example of epistatic effects of two genes on trachoma.

RESUMO

Tumour necrosis factor-alpha (TNF) expression is increased in inflammatory bowel disease (IBD), and TNF maps to the IBD3 susceptibility locus. Transmission disequilibrium and case-control analyses, in two independent Caucasian cohorts, showed a novel association of the TNF(-857C) promoter polymorphism with IBD (overall P=0.001 in 587 IBD families). Further genetic associations of TNF(-857C) with IBD sub-phenotypes were seen for ulcerative colitis and for Crohn's disease, but only in patients not carrying common NOD2 mutations. The genetic data suggest a recessive model of inheritance, and we observed ex vivo lipopolysaccharide-stimulated whole-blood TNF production to be higher in healthy TNF(-857C) homozygotes. We show the transcription factor OCT1 binds TNF(-857T) but not TNF(-857C), and interacts in vitro and in vivo with the pro-inflammatory NF(-kappa)B transcription factor p65 subunit at an adjacent binding site. Detailed functional analyses of these interactions in gut macrophages, in addition to further genetic mapping of this gene-dense region, will be critical to understand the significance of the observed association of TNF(-857C) with IBD.
