Background/Aims: The Korean guidelines for Helicobacter pylori treatment were revised in 2020, however, the extent of adherence to these guidelines in clinical practice remains unclear. Herein, we initiated a prospective, nationwide, multicenter registry study in 2021 to evaluate the current management of H.pylori infection in Korea. Methods: This interim report describes the adherence to the revised guidelines and their impact on firstline eradication rates. Data on patient demographics, diagnoses, treatments, and eradication outcomes were collected using a web-based electronic case report form. Results: A total of 7,261 patients from 66 hospitals who received first-line treatment were analyzed.The modified intention-to-treat eradication rate for first-line treatment was 81.0%, with 80.4% of the prescriptions adhering to the revised guidelines. The most commonly prescribed regimen was the 14-day clarithromycin-based triple therapy (CTT; 42.0%), followed by tailored therapy (TT; 21.2%), 7-day CTT (14.1%), and 10-day concomitant therapy (CT; 10.1%). Time-trend analysis demonstrated significant increases in guideline adherence and the use of 10-day CT and TT, along with a decrease in the use of 7-day CTT (all p<0.001). Multivariate logistic regression analysis revealed that guideline adherence was significantly associated with first-line eradication success (odds ratio, 2.03; 95% confidence interval, 1.61 to 2.56; p<0.001). Conclusions The revised guidelines for the treatment of H. pylori infection have been increasingly adopted in routine clinical practice in Korea, which may have contributed to improved first-line eradication rates. Notably, the 14-day CTT, 10-day CT, and TT regimens are emerging as the preferred first-line treatment options among Korean physicians.

Purpose: Emphysematous pyelonephritis (EPN) is a life-threatening disease requiring immediate treatment. This multicenter retrospective cohort study aimed to analyze the mortality rate and risk factors associated with EPN. Materials and Methods: Between January 2011 and February 2021, 217 patients diagnosed with EPN via computed tomography who visited 14 teaching hospitals were retrospectively analyzed. Clinical data, including age, sex, comorbidities, Huang and Tseng classification, hydronephrosis, acute kidney injury, blood and urine tests, surgical interventions, percutaneous drainage, and conservative treatments, were compared between the survival and death groups. Risk factors for mortality due to EPN were analyzed using univariate and multivariate methods. Results: The mean age of survivors and deceased patients was 67.8 and 69.0 years, respectively (p=0.136). The sex distribution (male/female) was 48/146 and 8/15, respectively (p=0.298). Of the 217 patients, 23 died, resulting in a mortality rate of 10.6%. In univariate analysis, the Huang and Tseng classification (p=0.004), platelet count (p=0.005), and acute kidney injury (p=0.007) were significantly associated with mortality from EPN. In multivariate analysis, only the Huang and Tseng classification (p=0.029) was identified as a risk factor. Mortality rates according to the Huang and Tseng classification were as follows: class I (5.88%), class II (7.50%), class IIIa (14.28%), class IIIb (25.00%), and class IV (23.07%). Conclusions EPN is associated with a high mortality rate. Among various clinical factors, the Huang and Tseng classification was the most significant indicator for predicting mortality.

Background/Aims: Little is known about the practical clinical application of neuromodulators and psychiatric treatments in patients with functional gastrointestinal disorders (FGIDs). We investigate the knowledge, attitudes, and practices of Korean clinicians regarding the use of neuromodulators and psychiatric treatments for FGIDs. Methods: This prospective, online, cross-sectional study was conducted between May and August 2022. A questionnaire regarding the knowledge, attitude, and practice of neuromodulators and psychiatric treatments for FGIDs was developed and administered to primary care clinicians and gastroenterologists in university hospitals in Korea. Results: Overall, 451 clinicians from primary (n = 179, 39.7%), secondary (n = 113, 25.1%), and tertiary (n = 159, 35.3%) hospitals participated in the survey. Most of them considered that neuromodulators (98.7%) and psychiatric treatment (86.5%) were required for patients with FGIDs. However, approximately one-third of them did not prescribe neuromodulators, mainly due to unfamiliarity with the drugs, and only one-quarter considered psychiatric referral. Compared to gastroenterologists at university hospitals, primary care clinicians’ prescriptions had a lower rate (87.2% vs 64.2%, P < 0.001) and shorter duration of neuromodulator. The psychiatric referral rate was lower for primary care clinicians than for gastroenterologists at university hospitals (19.0% vs 34.2%, P < 0.001). Conclusions Knowledge, attitude, and practice levels regarding neuromodulators and psychiatric treatment among clinicians are inhomogeneous, and a knowledge gap exists between primary care clinicians and gastroenterologists at university hospitals. Encouraging ongoing education for Korean clinicians regarding the appropriate use of neuromodulators and psychiatric treatments in patients with FGIDs is suggested.
