Atopic eczema is a chronic inflammatory disease where the skin barrier has become leaky, and inflammation occurs. It affects up to 20% of children and 3% of adults worldwide, manifesting as red itchy patches of skin with varying severity. This review aims to investigate the leaky skin barrier and immune mechanisms from the perspective of potential novel treatments. The complexity of atopic eczema as a disease is what makes it difficult to treat. Genome-wide association studies have highlighted possible genetic variations associated with atopic eczema, however in some cases, individuals develop the disease without these genetic risk factors. Loss of function mutations in the filaggrin gene are one of these associations and this is plausible due to its key role in barrier function. The Th2 immune response is the link with regards to the immune mechanisms as atopic inflammation often occurs through increased levels of interleukin(IL)-4 and IL-13. Eczematous inflammation also creates susceptibility to colonisation and damage by bacteria such as Staphylococcus aureus. Potential novel treatments are becoming ever more specific, offering the hope of fewer side effects and better disease control. The best new treatments highlighted in this review target the immune response with human beta defensin 2, phosphodiesterase-4 inhibitors and monoclonal antibodies all showing promise.展开更多

As such, these products need to be tested to evaluate their skin irritation and sensitization potential before use. The products were evaluated with two separate tests. The first test was conducted in a single-center, within-subject comparison using assessor-blind, randomised human skin irritation patch test (48 hour/96 hour exposure) and conducted on healthy adults with sensitive, atopic skin. The second test was conducted in a single-center, controlled (sterile water), within subject using human repeat-insult patch tests (HRIPTs) and conducted on healthy female Indonesian and Asian adult female subjects, with sensitive skin. The sensitization potential of each product was determined from International Contact Dermatitis Research Group (ICDRG) scores at 30 minutes, 24 hours, 48 hours and 72 hours after patch removal. Skin irritation tests show that all products were significantly lower than the positive control sodium lauryl sulphate (SLS) (p < 0.05) but not significantly different to the negative control (sterile water) in terms of irritation scores at the respective time points. HRIPTs results show that Cussons Baby Sensicare Range was non-sensitizing. As such, it can be concluded that the Cussons Baby Sensicare Range tested is well tolerated on skin and has low skin irritation and sensitization potential. Thus, they can be considered hypoallergenic on sensitive skin and suitable for eczema prone skin.展开更多
