Abstract:
Olmesartan induced enteropathy was first described in 2012. It is a rare adverse effect of this antihypertensive drug. The clinical presentation commonly includes severe chronic diarrhea leading to weight loss and a variable degree of dehydration. Histological findings are most commonly observed in the duodenum and consist of partial or total villous atrophy, increased intraepithelial lymphocytes and inflammation in the lamina propria. Involvement of gastric and colic mucosa has also been described. We report on the case of a 63-year-old man, treated by olmesartan, who presented with severe chronic diarrhea. Biopsies from different levels of the gastrointestinal tract revealed a pandigestive intraepithelial lymphocytosis.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
