Severe persistent unremitting dermatitis, chronic diarrhea and hypoalbuminemia in a child; Hartnupdisease in setting of celiac disease. Celiac disease (CD) is a complex autoimmune disorder that can lead to an inflammatory small intestinal villous atrophy and malabsorption. Hartnupdisease is an autosomal recessive disorder caused by increased urinary excretion of neutral amino acids. Co -occurrence of Hartnupdisease and CD is extremely rare with only a single case reported. We report a 3-year girl with chronic diarrhea, Hypoalbuminemia and exfoliative erythema. She was diagnosed with celiac disease, which did not improve on gluten free diet. Hartnupdisease was suspected and was confirmed by neutral aminoaciduria. Niacin was started and followed by dramatic improvement. Presence of Celiac
syrup urine disease, pyruvate dehydrogenase deficiency, and Hartnupdisease can also present with intermittent ataxia during times of stress or illness [1,36,37]; imaging in these cases may be helpful in identifying and characterizing the underlying neurometabolic disease. Children with rotational occlusion of the vertebral artery, also known as bow hunter syndrome, may present
groups:Diets based mainly on corn (low in tryptophan and niacin) - eg, China, Africa and India.Alcoholics - usually deficient in other vitamins also.Eating disorders - eg, anorexia nervosa.[2]Hartnup'sdisease - congenital malabsorption of tryptophan from the intestine and kidney.Carcinoid syndrome - tryptophan is increasingly converted to serotonin.There is concern that the number of cases of pellagra
-protein diet, avoidance of sunlight, use of sun protection and neurological and psychiatric treatment where there is CNS involvement.Nicotinic acid or nicotinamide at 50 mg to 300 mg daily can provide remission from both the skin and neurological manifestations. Maternal Hartnupdisease does not have an adverse effect on the fetus.[18]ComplicationsSevere CNS involvement may, rarely, be fatal diseases.

loss of function of NAPRT1 leads to abnormal brain development. Bioinformatic analyses and cellular and zebrafish gene expression studies implicate NAPRT1 as a novel susceptibility gene. Given this gene's role in niacin metabolism and the evidence for niacin deficiency provoking schizophrenialike symptoms in neuropsychiatric diseases such as pellagra and Hartnupdisease, these results suggest

availability of tryptophan may lead to a secondary deficiency of the vitamin niacin (nicotinic acid). [26, 27] * * Gene, inheritance, and pathogenesis: The locus associated with Hartnupdisease is 5p15. This autosomal recessive disorder is caused by defective intestinal transport and renal tubular reabsorption of neutral amino acids (primarily tryptophan). Hartnup disorder is caused by mutations
