No cure for<unk>  is known, although treatments may reduce the severity and frequency of flares. Humidity A humidifier can be used to prevent low indoor humidity during winter (especially with indoor heating), and dry season. And a dehumidifier can be used during seasons with excessive humidity. Applying moisturisers may prevent the skin from drying out and decrease the need for other medications. Affected persons often report that improvement of skin hydration parallels with improvement in<unk>  symptoms. Lifestyle Health professionals often recommend that persons with<unk>  bathe regularly in lukewarm baths, especially in salt water, to moisten their skin. Avoiding woolen clothing is usually good for those with<unk> . Likewise silk, silver-coated clothing may help. Dilute bleach baths have also been reported effective at managing<unk> . Diet The role of vitamin D on<unk>  is not clear, but some evidence shows that vitamin D supplementation may improve its symptoms. Studies have investigated the role of long-chain polyunsaturated fatty acid (LCPUFA) supplementation and LCPUFA status in the prevention and treatment of<unk> , but the results are controversial. Whether the nutritional intake of n-3 fatty acids has a clear preventive or therapeutic role, or if n-6 fatty acids consumption promotes<unk>  diseases is unclear. Several probiotics seem to have a positive effect, with a roughly 20% reduction in the rate of<unk> . The best evidence is for multiple strains of bacteria. In people with celiac disease or nonceliac gluten sensitivity, a gluten-free diet improves their symptoms and prevents the occurrence of new outbreaks. Medication<unk> al corticosteroids, such as hydrocortisone, have proven effective in managing<unk> . If<unk> al corticosteroids and moisturisers fail, short-term treatment with<unk> al calcineurin inhibitors such as tacrolimus or pimecrolimus may be tried, although their use is controversial, as some studies indicate that they increase the risk of developing skin cancer or lymphoma. A 2007 meta-analysis showed that<unk> al pimecrolimus is not as effective as corticosteroids and tacrolimus. A 2015 meta-analysis, though, indicated that<unk> al tacrolimus and pimecrolimus are more effective than low-dose<unk> al corticosteroids, and found no evidence for increased risk of malignancy or skin atrophy. In 2016, crisaborole, an inhibitor of PDE-4, was approved as<unk> al treatment for mild-to-moderate eczema. Other medications used for<unk>  include systemic immunosuppressants such as ciclosporin, methotrexate, interferon gamma-1b, mycophenolate mofetil, and azathioprine. Antidepressants and naltrexone may be used to control pruritus (itchiness). Leukotriene inhibitors such as monteleukast are of unclear benefit as of 2018. In 2017, the monoclonal antibody(mAb) dupilumab under the trade name Dupixent was approved to treat moderate-to-severe eczema. In 2021, an<unk> ditional monoclonal antibody, tralokinumab, was approved in the EU & UK with the trade name<unk> tralza then later in the US as<unk> bry for similarly severe cases.
