Is there a cure for sjögren syndrome?
Sjögren syndrome
Neither a cure for SS nor a specific treatment is known to permanently restore gland secretion. Instead, treatment is generally symptomatic and supportive.
Conrad Elvehjem
Picking up on the work of Joseph Goldberger, he found that nicotinic acid cured black tongue in dogs, an analogous disease to pellagra. In the previous year, Elvehjem and his colleague Carl J. Koehn had found that a filtrate factor from a liver extract could cure diet-induced pellagra in chicks. That filtrate extract was designated as the vitamin G fraction, after the late Goldberger. To confirm their findings in dogs, they induced black tongue in these animals with the Goldberger diet of yellow corn, before supplementing the diet with the vitamin G fraction. Elvehjem and his colleagues later were able to isolate and identify nicotinamide and nicotonic acid from vitamin G as the curative factors for black tongue in dogs. He also contributed greatly to the identification of vitamin B complex and was co-author of more than 780 scientific papers on biochemistry and nutrition.
