Corrigendum to "celiac Disease or Positive Tissue Transglutaminase Antibodies in Patients Undergoing Renal Biopsies" [dig Liver Dis (2018);50:27-31].

The authors deeply apologize for an error that appeared in the article by Nurmi et al. in the issue of January 2018 of the Digestive and Liver Disease (Dig Liver Dis. 2018;50:27–31), entitled ‘Celiac disease or positive tissue transglutaminase antibodies in patients undergoing renal biopsies’. The error concerns the formula of eGFR (estimated glomerular filtration rate), which was formed erroneously. However, the correct values of creatinine and age were used. The wrong formula neither changes the end results nor the message of the study. The corrected sentences are as follows: ‘At the time of kidney biopsy and after a median follow-up of 5 to 6 years, renal function measured by estimated glomerular filtration rate (eGFR) was inferior in IgA nephropathy patients with celiac autoimmunity compared to those without it (P = 0.073 and P = 0.062, respectively)’ (in the abstract) and ‘It is notable that patients having celiac disease autoimmunity were found to have more severe kidney disease defined by the higher levels of creatinine and lower eGFR among this patient group’ (in the discussion). The new Table 3, which shows the correct values of eGFR is published in full below.
