The confusion was due to the fact that riboflavin (B 2) deficiency causes stomatitis symptoms similar to those seen in pellagra, but without the widespread peripheral skin lesions. For this reason, early in the history of identifying riboflavin deficiency in humans the condition was sometimes called "pellagra sine pellagra" (pellagra without ...
Vitamin deficiency is the condition of a long-term lack of a vitamin. When caused by not enough vitamin intake it is classified as a primary deficiency, whereas when due to an underlying disorder such as malabsorption it is called a secondary deficiency. An underlying disorder can have 2 main causes:
Riboflavin: Riboflavin deficiency can cause ariboflavinosis, which may result in cheilosis (cracks in the lips), high sensitivity to sunlight, angular cheilitis, glossitis (inflammation of the tongue), seborrheic dermatitis or pseudo-syphilis (particularly affecting the scrotum or labia majora and the mouth), pharyngitis (sore throat ...
Gastroenterostomy can also cause pellagra. [10] Chronic alcoholism can also cause poor absorption, which combined with a diet already low in niacin and tryptophan produces pellagra. [10] Hartnup disease is a genetic disorder that reduces tryptophan absorption, leading to pellagra. Alterations in protein metabolism may also produce pellagra-like ...
As vitamins go, vitamin B12 is a pretty important one. Vitamin B12 has a broad range of roles in our body -- from helping to make DNA and transport iron throughout our systems to protecting our ...
Riboflavin-responsive exercise intolerance (SLC25A32 deficiency) is a rare disorder caused by mutations of the SLC25A32 gene that encodes the mitochondrial folate transporter. Patients suffer from exercise intolerance and may have disrupted motor function.
In children a frequent cause is repeated lip-licking, and in adults it may be a sign of underlying iron deficiency anemia, or vitamin B deficiencies (e.g., B 2-riboflavin, B 9-folate, or B 12-cobalamin, which in turn may be evidence of poor diets or malnutrition such as celiac disease).
Potential deficiencies linked to hair health include vitamins B12, D, E, A, and biotin, riboflavin, folate, zinc, and iron. Ensuring sufficient amounts may help prevent hair loss. But, getting ...
