Nickel is a hard, silver-white metal found typically in nature. It is malleable and cost-effective, making it easy to work with. It is usually blended with different metals to make different things. For instance, beautifying products and contact lens solutions may also contain metals that can trigger an allergic response at the point of contact. Additionally, small amounts of nickel are present in numerous foods, including certain grains, organic products, and vegetables. It is also found in dental restorative material, prostheses (hip, knee, cochlear and cardiac implants),color pigments, stainless steel cutlery, pots and pans.
The exact reason for a nickel sensitivity isn’t known. However, analysts believe that the sensitivity to nickel may be hereditary, that is, acquired from a family member. In contrast to immediate hypersensitivities, (for example, dust, insect venom and food sensitivities), the reaction in nickel allergy is deferred type i.e. it happens some time after the exposure. Following the contact with an allergen, it can take 24 to 72 hours before the principal symptoms show up. This ‘delay’ is caused by what are called as helper T cells (medicinal term: T-lymphocytes). Helper T cells plays an essential role in the immune system and are found in the lymph nodes and inner layers of the skin. Their function is to ensure against certain infections. They append to foreign substances and activate other cells in the immune system to devastate the foreign substances. The so-called memory T cells are then framed. These cells remember precisely which invaders are unwanted so that they can respond quicker in case of re-exposure. In a contact hypersensitivity, the helper T cells probably remember a harmless substance like nickel. Just in case if the skin is again re-exposed to the ecological substance, the helper T cells will transform in the upper skin layers and cause a provocative response.
If earrings irritates your ear auricle or your necklet leaves a rash around your neck, you may be susceptible to nickel. A nickel sensitivity is a response that develops after repeated and prolonged exposure to nickel containing items. Degree of allergic reaction varies from person to person. Individual can be exposed to nickel through regular things, or one might be exposed to nickel in the working environment condition. Excess exposure to nickel makes the skin red and irritated at first – later on tiny blisters can show up, making the skin wet and messy. The skin may then strip off. The rashes can start in one part or at different parts of the body in the meantime. It is feasible for the rash to spread later on to even that body parts which haven’t come into contact with the metal. If the symptoms remains on the skin for the long time, the skin will dry out and ended up being red,scaly and very hard to clear up.
Your specialist may presume metal hypersensitivities based on the combination of your own personal history and your signs and symptoms. To determine possible causes of nickel exposure, your specialist may ask if you have any kind of implants, if you smoke, or if you routinely use any beautifying products. Beside a careful individual history, your specialist may arrange lab tests to affirm whether you have a nickel allergy. These tests involves blood test in laboratory. The laboratory specialists will test the white blood cells for their activity against metal(nickel) ions by utilizing radioisotopes and microscopically observing physical changes within the cells. If the test demonstrates that the white blood cells have increased activity when exposed to the nickel ions, it shows the presence of a nickel allergy.
A dermatologist can conduct a nickel sensitivity test in which they expose various nickel ions to your skin to test for a hypersensitivity response. This sensitivity test is also known as”patch test.”. During the patch test, your specialist applies a little amount of nickel over a patch. The patch is then set on your skin. This test is usually very safe and shouldn’t cause a major allergic response. They should only cause a minor reaction in individuals who are sensitive to nickel. Your specialist will observe your skin for around 48 hours after the patch test and check for signs of an unfavorably susceptible response. If the skin looks irritated, you might be adversely affected by nickel.
How can you prevent the nickel hypersensitivity? The best strategy to prevent a nickel sensitivity from developing is to avoid prolonged exposure to things containing nickel. However, it’s not always easy to keep away from nickel since it is present in huge numbers of items. Home test kits are available to check for nickel in the metal items. The following tips may help you to avoid nickel exposure:

There is no cure for nickel hypersensitivity. The best way to prevent allergic reaction is to avoid the allergen. Several medications including topical steroids, antibiotics may help to treat a rash that results from nickel allergic reaction. Some home cures may relieve and calm the skin. These incorporate calamine lotion, hydrating body moisturizer; cool and wet packs. If medications don’t soothe your symptoms, consult your specialists as soon as possible.
