AIM To estimate the risk of end-stage renal disease(ESRD)in patients with inflammatory bowel disease(IBD).METHODS From January 2010 to December 2013, patients with Crohn's disease(CD) and ulcerative colitis(UC) were identified, based on both the International Classification of Diseases, 10 th revision(ICD-10) and the rare,intractable disease registration program codes from the National Health Insurance(NHI) database in South Korea. We compared 38812 patients with IBD to ageand sex-matched non-IBD controls with a ratio of 1:*** newly diagnosed with ESRD were identified with the ICD-10 *** During a mean follow-up of 4.9 years, ESRD was detected in 79(0.2%) patients with IBD and 166(0.1%)controls. The incidence of ESRD in patients with IBD was0.42 per 1000 person-years. Patients with IBD had a significantly higher risk of ESRD than controls [adjusted hazard ratio(HR) = 3.03; 95% confidence interval(CI):1.77-5.20; P < 0.001]. The incidences(per 1000 personyears)of ESRD were 0.51 in patients with CD and 0.13 in controls, respectively(adjusted HR = 6.33; 95%CI:2.75-14.56; P < 0.001). In contrast, the incidence of ESRD was similar between the UC and control groups(0.37 vs 0.37 per 1000 person-years; adjusted HR = 2.01;95%CI: 0.90-4.51; P = 0.089).CONCLUSION The risk of ESRD was elevated in patients with CD, but not UC. Patients with CD should be monitored carefully for signs of renal insufficiency.

Dear editor,Severe acute respiratory syndrome coronavirus2(SARS-CoV-2)infection can lead to severe outcomes in patients with cancer[1].It has been reported that patients with lung cancers disproportionately manifest severe COVID-19 with a high rate of hospitalization and death[2].Notably,the SARS-CoV-2 Spike(S)protein can induce hyper-inflammation in both epithelial cells and macrophages through toll-like receptor(TLR)1/TLR2 or TLR2/6-dependent nuclear factor-kappaB(NF-κB)path-way[3].However,molecular and cellular evidence on whether the SARS-CoV-2 virus affects the severity of lung cancer patients through TLR1/2 or TLR2/6 signaling remains unclear.
