RÉSUMÉ
Background@#This study evaluated the efficacy and safety of add-on gemigliptin in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycemic control with metformin and dapagliflozin. @*Methods@#In this randomized, placebo-controlled, parallel-group, double-blind, phase III study, 315 patients were randomized to receive either gemigliptin 50 mg (n=159) or placebo (n=156) with metformin and dapagliflozin for 24 weeks. After the 24-week treatment, patients who received the placebo were switched to gemigliptin, and all patients were treated with gemigliptin for an additional 28 weeks. @*Results@#The baseline characteristics were similar between the two groups, except for body mass index. At week 24, the least squares mean difference (standard error) in hemoglobin A1c (HbA1c) changes was –0.66% (0.07) with a 95% confidence interval of –0.80% to –0.52%, demonstrating superior HbA1c reduction in the gemigliptin group. After week 24, the HbA1c level significantly decreased in the placebo group as gemigliptin was administered, whereas the efficacy of HbA1c reduction was maintained up to week 52 in the gemigliptin group. The safety profiles were similar: the incidence rates of treatment-emergent adverse events up to week 24 were 27.67% and 29.22% in the gemigliptin and placebo groups, respectively. The safety profiles after week 24 were similar to those up to week 24 in both groups, and no new safety findings, including hypoglycemia, were noted. @*Conclusion@#Add-on gemigliptin was well tolerated, providing comparable safety profiles and superior efficacy in glycemic control over placebo for long-term use in patients with T2DM who had poor glycemic control with metformin and dapagliflozin.
RÉSUMÉ
Background@#To evaluate the effects of teneligliptin on glycosylated hemoglobin (HbA1c) levels, continuous glucose monitoring (CGM)-derived time in range, and glycemic variability in elderly type 2 diabetes mellitus patients. @*Methods@#This randomized, double-blinded, placebo-controlled study was conducted in eight centers in Korea (clinical trial registration number: NCT03508323). Sixty-five participants aged ≥65 years, who were treatment-naïve or had been treated with stable doses of metformin, were randomized at a 1:1 ratio to receive 20 mg of teneligliptin (n=35) or placebo (n=30) for 12 weeks. The main endpoints were the changes in HbA1c levels from baseline to week 12, CGM metrics-derived time in range, and glycemic variability. @*Results@#After 12 weeks, a significant reduction (by 0.84%) in HbA1c levels was observed in the teneligliptin group compared to that in the placebo group (by 0.08%), with a between-group least squares mean difference of –0.76% (95% confidence interval [CI], –1.08 to –0.44). The coefficient of variation, standard deviation, and mean amplitude of glycemic excursion significantly decreased in participants treated with teneligliptin as compared to those in the placebo group. Teneligliptin treatment significantly decreased the time spent above 180 or 250 mg/dL, respectively, without increasing the time spent below 70 mg/dL. The mean percentage of time for which glucose levels remained in the 70 to 180 mg/dL time in range (TIR70–180) at week 12 was 82.0%±16.0% in the teneligliptin group, and placebo-adjusted change in TIR70–180 from baseline was 13.3% (95% CI, 6.0 to 20.6). @*Conclusion@#Teneligliptin effectively reduced HbA1c levels, time spent above the target range, and glycemic variability, without increasing hypoglycemia in our study population.

RÉSUMÉ
Hypoglycemia is common but can lead to life-threatening consequences. Accurate diagnosis is important to establish the appropriate treatment strategy. Most cases of hypoglycemia are caused by hypoglycemic agents, although it can occur in individuals without diabetes. A systemic and comprehensive diagnostic approach is required to diagnose hypoglycemia in patients without diabetes. It is important to perform appropriate blood testing during an episode of hypoglycemia. This review will focus on the definition, differential diagnosis, causes, and treatment of hypoglycemia, particularly in people without diabetes.

Hypertension is a major risk factor for cardiovascular disease in diabetic as well as non-diabetic patients. Moreover, the presence of diabetes increases the risk of developing hypertension. The management of these two diseases will become even more important in our aging society. Despite significant advances in our understanding of the pathophysiology and treatment of hypertension, the management of hypertension remains controversial, especially in patients with diabetes. In particular, the blood pressure at which to initiate drug therapy and blood pressure target remain unclear. Recently, the Korean Diabetes Association published “Treatment Guideline for Diabetes 2019”. This review will mainly compare major guidelines from other countries and discuss how to select a target goal for blood pressure control in Korean diabetic patients. Lifestyle modification and the use of anti-hypertensive agents for the management of hypertension will also be discussed.

Purpose@#This study sought to investigate the prognostic significance of tumor-infiltrating lymphocytes (TILs) in relation to tumor location within the stomach. @*Materials and Methods@#The densities and prognostic significance of TIL subsets were evaluated in 542 gastric cancer patients who underwent gastrectomy. Immunohistochemical staining for CD3, CD4, CD8, forkhead/winged helix transcription factor (Foxp3), and granzyme B was performed. @*Results@#Cardia cancer was associated with significantly lower densities of CD8 T-cells and higher densities of Foxp3 and granzyme B T-cells than non-cardia tumors. Multivariate analysis showed that advanced age (hazard ratio [HR], 1.023; 95% confidence interval [CI], 1.006–1.040), advanced T classification (HR, 2.029; 95% CI, 1.106–3.721), lymph node metastasis (HR, 3.319; 95% CI, 1.947–5.658), low CD3 expression (HR, 0.997; 95% CI, 0.994–0.999), and a high Foxp3/CD4 ratio (HR, 1.007; 95% CI, 1.001–1.012) were independent predictors of poor overall survival in cardia cancer patients. In non-cardia cancer patients, total gastrectomy (HR, 2.147; 95% CI, 1.507–3.059), advanced T classification (HR, 2.158; 95% CI, 1.425–3.266), lymph node metastasis (HR, 1.854; 95% CI, 1.250–2.750), and a low Foxp3/CD4 ratio (HR, 0.978; 95% CI, 0.959–0.997) were poor prognostic factors for survival. @*Conclusions@#The densities and prognostic effects of TILs differed in relation to the location of tumors within the stomach. The contrasting prognostic effects of Foxp3/CD4 ratio in cardia and non-cardia gastric cancer patients suggests that clinicians ought to consider tumor location when determining treatment strategies.
RÉSUMÉ
PURPOSE: The efficacy of exclusive enteral nutrition (EEN) with a polymeric diet has not been confirmed in Korean pediatric patients with Crohn's disease (CD). This study aimed to compare the effectiveness of EEN with a specific polymeric diet (Encover®) and corticosteroids (CSs) for the induction of remission in Korean pediatric CD patients. METHODS: We retrospectively compared data from 51 pediatric CD patients who underwent induction therapy with EEN (n=19) or CSs (n=32) at Severance Children's Hospital or Incheon St. Mary's Hospital in Korea. The primary endpoint of this study was the rate of clinical remission, defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score < 10, after 8 weeks of induction treatment. Clinical, laboratory, and growth data at post-induction as well as their changes from baseline were also compared between groups. RESULTS: After 8 weeks of induction therapy, clinical remission rates were 78.9% (15/19) and 65.6% (21/32) in the EEN and CS groups, respectively (p=0.313). No significant differences in PCDAI scores, laboratory variables, and growth parameters were noted between the two groups at post-induction. However, significant changes in albumin levels at post-induction were observed in the EEN group compared to the CS group (p=0.038). CONCLUSION: Our results suggest that the effectiveness of EEN with a polymeric diet and CSs for induction therapy did not differ in Korean pediatric CD patients. EEN with a polymeric diet is a good first-line treatment option for the induction of remission in these patients.

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association revised and updated the 6th Clinical Practice Guidelines in 2019. Targets of glycemic, blood pressure, and lipid control in type 2 diabetes mellitus (T2DM) were updated. The obese and overweight population is increasing steadily in Korea, and half of the Koreans with diabetes are obese. Evidence-based recommendations for weight-loss therapy for obesity management as treatment for hyperglycemia in T2DM were provided. In addition, evidence from large clinical studies assessing cardiovascular outcomes following the use of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide 1 receptor agonists in patients with T2DM were incorporated into the recommendations.

PURPOSE: The aim of this study was to evaluate the clinical significance of inflammatory biomarkers in acute infectious diarrhea among children. METHODS: Clinical parameters including fever, bacterial and viral etiology based on stool culture and multiplex polymerase chain reaction, and nine biomarkers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leukocytes in blood and calprotectin, lactoferrin, myeloperoxidase, polymorphonuclear elastase, leukocytes, and occult blood in feces were evaluated in children who were hospitalized due to acute diarrhea without underlying disease. RESULTS: A total of 62 patients were included. Among these patients, 33 had fever, 18 showed bacterial infections, and 40 patients were infected with 43 viruses. Of all the biomarkers, CRP was significantly correlated with fever (p<0.001). CRP, ESR, calprotectin, lactoferrin, myeloperoxidase, fecal leukocytes, and occult blood were significantly associated with infection with bacterial pathogens (p<0.001, p=0.04, p=0.03, p=0.003, p=0.02, p=0.03, p=0.002, respectively). The combination of CRP and fecal lactoferrin at their best cut-off values (13.7 mg/L and 22.8 µg/mL, respectively) yielded a sensitivity of 72.2%, and a specificity of 95.5% for bacterial etiology compared with their individual use. CONCLUSION: Blood CRP is a useful diagnostic marker for both fever and bacterial etiology in acute pediatric diarrhea. The combination of CRP and fecal lactoferrin yields better diagnostic capability for bacterial etiology than their use alone for acute diarrhea in children without underlying gastrointestinal disease.

Diabetes mellitus is associated with a high frequency of complications related to cardiovascular disease as well as microvascular complications such as nephropathy, retinopathy, and neuropathy. Prevention of these vascular complications is the main issue for diabetic patients. Hyperglycemia, hypertension, and dyslipidemia are well-known risk factors for complications in diabetic patients. Moreover, these chronic conditions are often seen in many diabetic patients. So, multifactorial interventions are needed to manage these risk factors and prevent diabetic complications. However, there is still a debate about the optimal level required for glycemic control, the appropriate blood pressure target, and dyslipidemia management. Although many countries have written their own guidelines, there are some discrepancies between these different guidelines. Recently, the Korean Diabetic Association issued new guidelines for Korean diabetic patients. Here, I will introduce these new guidelines and discuss the optimal management of risk factors such as hyperglycemia, hypertension, and dyslipidemia in diabetic patients.

Cardiovascular disease, including stroke, is one of the major causes of death in diabetes. Numerous studies have long suggested reducing macrovascular complication such as ischemic vascular disease through intensive glycemic control, but none was successful proving the effect of glycemic control. Recently, new possibilities in cardiovascular disease reduction have been proposed through cardiovascular safety trials of newly developed anti-hyperglycemic agents. The purpose of this review is to introduce the traditional and newly developed anti-diabetic medications and review their effects regarding cardiovascular outcomes mainly focusing on stroke.

Streptococcus dysgalactiae has two main subspecies: S. dysgalactiae subsp. equisimilis (SDSE) and S. dysgalactiae subsp. dysgalactiae (SDSD). SDSE often colonizes and causes infections in humans; however, SDSD is an animal pathogen which often causes pyogenic infection in domestic animals. We present a case of meningitis with SDSD and herpes simplex virus in a 22-day-old newborn baby who had no exposure to animals.

BACKGROUND: We evaluated the clinical characteristics of insulin resistance and β-cell dysfunction in newly diagnosed, drug-naive people with type 2 diabetes by analyzing nationwide cross-sectional data. METHODS: We collected the clinical data of 912 participants with newly diagnosed diabetes from 83 primary care clinics and hospitals nationwide from 2015 to 2016. The presence of insulin resistance and β-cell dysfunction was defined as a homeostatic model assessment of insulin resistance (HOMA-IR) value ≥2.5 and fasting C-peptide levels < 1.70 ng/mL, respectively. RESULTS: A total of 75.1% and 22.6% of participants had insulin resistance and β-cell dysfunction, respectively. The proportion of participants with insulin resistance but no β-cell dysfunction increased, and the proportion of participants with β-cell dysfunction but no insulin resistance decreased as body mass index (BMI) increased. People diagnosed with diabetes before 40 years of age had significantly higher HOMA-IR and BMI than those diagnosed over 65 years of age (HOMA-IR, 5.0 vs. 3.0; BMI, 28.7 kg/m2 vs. 25.1 kg/m2). However, the β-cell function indices were lower in people diagnosed before 40 years of age than in those diagnosed after 65 years of age (homeostatic model assessment of β-cell function, 39.3 vs. 64.9; insulinogenic index, 10.3 vs. 18.7; disposition index, 0.15 vs. 0.25). CONCLUSION: We observed that the main pathogenic mechanism of type 2 diabetes is insulin resistance in participants with newly diagnosed type 2 diabetes. In addition, young adults with diabetes are more likely to have higher insulin resistance with obesity and have higher insulin secretory defect with severe hyperglycemia in the early period of diabetes than older populations.

PURPOSE: The tumor microenvironment is known to be associated with the metabolic activity of cancer cells and local immune reactions. We hypothesized that glucose metabolism measured by 2-deoxy-2-(¹⁸F)fluoro-D-glucose (¹⁸F-FDG) positron emission tomography (PET)-computed tomography (CT) (¹⁸F-FDG PET-CT) would be associated with local immune responses evaluated according to the presence of tumor infiltrating lymphocytes (TILs). MATERIALS AND METHODS: We retrospectively reviewed 56 patients who underwent ¹⁸F-FDG PET-CT prior to gastrectomy. In resected tumor specimens, TIL subsets, including cluster of differentiation (CD) 3, CD4, CD8, Forkhead box P3 (Foxp3), and granzyme B, were subjected to immunohistochemical analysis. The prognostic nutritional index (PNI) was calculated as: (10×serum albumin value)+(0.005×peripheral lymphocyte counts). Additionally, the maximum standard uptake value (SUVmax) was calculated to evaluate the metabolic activity of cancer cells. RESULTS: The SUVmax was positively correlated with larger tumor size (R=0.293; P=0.029) and negatively correlated with PNI (R=−0.407; P=0.002). A higher SUVmax showed a marginal association with higher CD3 (+) T lymphocyte counts (R=0.227; P=0.092) and a significant association with higher Foxp3 (+) T lymphocyte counts (R=0.431; P=0.009). No other clinicopathological characteristics were associated with SUVmax or TILs. Survival analysis, however, indicated that neither SUVmax nor Foxp3 held prognostic significance. CONCLUSIONS: FDG uptake on PET-CT could be associated with TILs, especially regulatory T cells, in gastric cancer. This finding may suggest that PET-CT could be of use as a non-invasive tool for monitoring the tumor microenvironment in patients with gastric cancer.

Familial adenomatous polyposis (FAP) is a precancerous clinical entity, which is characterized by the development of numerous adenomatous polyps throughout the colon and rectum. The majority of FAP are associated with mutations of the adenomatous polyposis coli (APC) gene. Until now, more than 1,000 different APC mutations have been reported and some mutations express attenuated phenotypes which are milder forms with 10~100 colorectal polyps. We identified a novel mutation of APC gene which expressed an attenuated FAP but caused large gastroduodenal tubular adenomas requiring repeated endoscopic resections. A 16-year-old girl was referred to Incheon St. Mary's Hospital for evaluation of gastric polyposis. Initial esophagogastroduodenoscopy (EGD) showed numerous gastric polyps in the fundus and upper body and a few polyps in the duodenum. Pathologic examination confirmed gastric polyps as fundic gland polyps and duodenal polyps as tubular adenomas. Only a few colonic polyps of 2 to 5 mm in size were found on colonoscopy. Genetic analysis using polymerase chain reaction and direct sequencing revealed a novel stop codon mutation at codon 1522 in exon 16 of APC gene. At 12-month, 18-month, and 35-month follow-up EGD, large duodenal polyp and gastric polyps were removed endoscopically.
