What is pilocarpine iontophoresis?
Pilocarpine nitrate is a cholinergic agent that binds to muscarinic receptors of eccrine sweat glands and induces sweat production.
What is iontophoresis?
Iontophoresis is a treatment for hyperhidrosis — or excessive sweating. It involves sending a gentle electrical current through water to shut down your sweat glands temporarily. If it works for you, you’ll have to keep doing the treatments to maintain the results.
What is the process of iontophoresis?
Iontophoresis is the process of passing a weak electrical current through the skin. Iontophoresis has a variety of uses in medicine. This article discusses the use of iontophoresis to decrease sweating by blocking sweat glands.
What is pilocarpine in cystic fibrosis?
Cystic fibrosis is diagnosed in infants by estimating the levels of chloride ions present in the sweat induced by iontophoresis of pilocarpine solution. Elevated levels of chloride (≥60 mMol/L) in sweat are indicative of cystic fibrosis.
How does sweat chloride test work?
The sweat test measures the amount of chloride in sweat. Kids with cystic fibrosis can have two to five times the normal amount of chloride in their sweat. In a sweat test, the skin is stimulated to produce enough sweat to be absorbed into a special collector and then analyzed.
Why is chloride increased in cystic fibrosis?
People who have CF have higher levels of chloride in their sweat because chloride is unable to move in or out of the body’s cells, which is what causes it to build up. A sweat test is usually done if a child may be at risk for inheriting CF, or if he or she is showing symptoms.
What causes cystic fibrosis?
It’s an inherited disease caused by a defective gene that can be passed from generation to generation. Cystic fibrosis affects the cells that produce mucus, sweat and digestive juices. These secreted fluids are normally thin and slippery. But in people with CF, they’re thick and sticky.
What is a normal sweat chloride level?
Normal sweat chloride concentration is 29 mmol/L or less (Farrell 2017). Intermediate sweat chloride concentration is 30-59 mmol/L (Farrell 2017). Intermediate sweat chloride values have been documented in genetically proven cystic fibrosis.
What causes high chloride in sweat?
A sweat test measures the amount of chloride, a part of salt, in Sweat. It is used to diagnose cystic fibrosis (CF). People with CF have a high level of chloride in their sweat. CF is a disease that causes mucus build-up in the lungs and other organs.
Why sweat is salty in cystic fibrosis?
Why do people with CF have salty skin? In people with CF there is a problem in the transport of chloride across cell membranes. This causes thicker, stickier mucus in the lungs and digestive system, but also results in higher levels of chloride (as salt) in sweat compared with those who do not have cystic fibrosis.
