Despite the elevated levels of lactoferrin and calprotectin, none of HIV+ groups surpassed the established cut-off to determine intestinal inflammation in Inflammatory Bowel Disease (IBD) in non-HIV+ subjects: 7.25 μg/g of stool for lactoferrin and 90.85 μg/g for calprotectin (Table 2); however, 50 and 44% of INRs present elevated levels (above 75th percentile) of lactoferrin and calprotectin, respectively [22–24]. This evidence concerns the gene LTF and gastroenteritis.
