Changes in Characteristics of Patients with Liver Cirrhosis Visiting a Tertiary Hospital over 15 Years: a Retrospective Multi-Center Study in Korea

Background@#Liver cirrhosis has become a heavy burden not only for patients, but also for our society. However, little is known about the recent changes in clinical outcomes and characteristics of patients with cirrhosis-related complications in Korea. Therefore, we aimed to evaluate changes in characteristics of patients with liver cirrhosis in Daegu-Gyeongbuk province in Korea over the past 15 years. @*Methods@#We retrospectively reviewed the medical records of 15,716 liver cirrhotic patients from 5 university hospitals in Daegu-Gyeongbuk province from 2000 to 2014. The Korean Standard Classification of Diseases-6 code associated with cirrhosis was investigated through medical records and classified according to the year of first visit. @*Results@#A total of 15,716 patients was diagnosed with cirrhosis. A number of patients newly diagnosed with cirrhosis has decreased each year. In 2000, patients were most likely to be diagnosed with hepatitis B virus (HBV) cirrhosis, followed by alcoholic cirrhosis. There was a significant decrease in HBV (P < 0.001), but alcohol, hepatitis C virus (HCV), and non-alcoholic fatty liver disease (NAFLD) showed a significant increase during the study period (alcohol, P = 0.036; HCV, P = 0.001; NAFLD, P = 0.001). At the time of initial diagnosis, the ratio of Child-Turcotte-Pugh (CTP) class A gradually increased from 23.1% to 32.9% (P < 0.001). The most common cause of liver-related hospitalization in 2000 was hepatocellular carcinoma (HCC) (25.5%); in 2014, gastrointestinal bleeding with esophageal and gastric varices (21.4%) was the most common cause. Cases of hospitalization with liver-related complication represented 76.4% of all cases in 2000 but 70.9% in 2014. Incidence rate of HCC has recently increased. In addition, HCC-free survival was significantly lower in CTP class A than in classes B and C. Finally, there was significant difference in HCC occurrence according to causes (P < 0.001). HBV and HCV cirrhosis had lower HCC-free survival than alcoholic and NAFLD cirrhosis. @*Conclusion@#In recent years, the overall number of cirrhosis patients has decreased. This study confirmed the recent trend in decrease of cirrhosis, especially of cirrhosis due to HBV, and the increase of HCV, alcoholic and NAFLD cirrhosis. Targeted screening for at-risk patients will facilitate early detection of liver diseases allowing effective intervention and may have decreased the development of cirrhosis and its complications.

A Case of Gastro-Gastric Intussusception Secondary to Primary Gastric Lymphoma / 대한소화기학회지

In adults, most intussusceptions develop from a lesion, usually a benign or malignant neoplasm, and can occur at any site in the gastrointestinal tract. Intussusception in the proximal gastrointestinal tract is uncommon, and gastro-gastric intussusception is extremely rare. We present a case of gastro-gastric intussusception secondary to a primary gastric lymphoma. An 82-year-old female patient presented with acute onset chest pain and vomiting. Abdominal CT revealed a gastro-gastric intussusception. We performed upper gastrointestinal endoscopy, revealing a large gastric mass invaginated into the gastric lumen and distorting the distal stomach. Uncomplicated gastric reposition was achieved with endoscopy of the distal stomach. Histological evaluation of the gastric mass revealed a diffuse large B cell lymphoma that was treated with chemotherapy.

Comparison between Endoscopic Therapy and Medical Therapy in Peptic Ulcer Patients with Adherent Clot: A Multicenter Prospective Observational Cohort Study / 대한소화기학회지

BACKGROUND/AIMS: The optimal management of bleeding peptic ulcer with adherent clot remains controversial. The purpose of this study was to compare clinical outcome between endoscopic therapy and medical therapy. We also evaluated the risk factors of rebleeding in Forrest type IIB peptic ulcer. METHODS: Upper gastrointestinal (UGI) bleeding registry data from 8 hospitals in Korea between February 2011 and December 2013 were reviewed and categorized according to the Forrest classification. Patients with acute UGI bleeding from peptic ulcer with adherent clots were enrolled. RESULTS: Among a total of 1,101 patients diagnosed with peptic ulcer bleeding, 126 bleedings (11.4%) were classified as Forrest type IIB. Of the 126 patients with adherent clots, 84 (66.7%) received endoscopic therapy and 42 (33.3%) were managed with medical therapy alone. The baseline characteristics of patients in two groups were similar except for higher Glasgow Blatchford Score and pre-endoscopic Rockall score in medical therapy group. Bleeding related mortality (1.2% vs. 10%; p=0.018) and all cause mortality (3.7% vs. 20.0%; p=0.005) were significantly lower in the endoscopic therapy group. However, there was no difference between endoscopic therapy and medical therapy regarding rebleeding (7.1% vs. 9.5%; p=0.641). In multivariate analysis, independent risk factors of rebleeding were previous medication with aspirin and/or NSAID (OR, 13.1; p=0.025). CONCLUSIONS: In patients with Forrest type IIB peptic ulcer bleeding, endoscopic therapy was associated with a significant reduction in bleeding related mortality and all cause mortality compared with medical therapy alone. Important risk factor of rebleeding was use of aspirin and/or NSAID.

Trend in the Eradication Rates of Helicobacter pylori Infection in the Last 8 Years in Daegu: A Single Center Experience

BACKGROUND/AIMS: Helicobacter pylori eradication rates achieved by first-line triple treatment with proton pump inhibitor (PPI), clarithromycin, and amoxicillin have decreased to 70~85%, in part due to increasing antimicrobial resistance. This study evaluated the trend in H. pylori eradication rates during the most recent 8 years in Daegu, Korea and analyzed different clinical factors between success group and failure group of H. pylori eradication. MATERIALS AND METHODS: This was a retrospective study at a single institution. A total of 768 H. pylori-positive patients who received one or two weeks of first-line triple regimens were included between January 2007 and October 2014. RESULTS: The overall H. pylori eradication rate was 86%. The eradication rate from years 2007 to 2014 was 80.5%, 89.4%, 95.6%, 85.5%, 87.9%, 75.8%, 83.3%, and 85.8%, respectively (P=0.027). There was no significant difference in the eradication rate among various PPIs (P=0.358). In addition, there were no significant difference of clinical factors between success and failure group of H. pylori eradication. CONCLUSIONS: The eradication rates of first-line triple therapy for H. pylori over 8 years were 75.8~95.6%. No significant difference in clinical factors were noted between success and failure group of H. pylori eradication. Triple therapy may be a useful regimen for H. pylori eradication in Daegu.

Renal Infarction in Antiphospholipid Antibody-negative Pediatric Systemic Lupus Erythematosus Patient

Systemic lupus erythematosus (SLE) is an autoimmune disease affecting multiple organ systems, and is characterized by the deposition of immune complexes and a large array of autoantibodies. Thrombosis is a relatively frequent and serious complication of SLE; however, renal infarction in young patients with antiphospholipid antibody-negative lupus has rarely been reported, and no pediatric case has been reported in Korea. A 12-year-old female patient was presented to our hospital with a 3-day history of nausea, vomiting, and right flank pain. She was diagnosed with SLE and lupus nephritis two years ago and was treated with corticosteroids and hydroxychloroquine, azathioprine. Abdominal computed tomography (CT) showed renal infarction in the upper pole of the right kidney. Subcutaneous low molecular weight heparin was started, and warfarin was also started simultaneously and continued for 3 months. After 3 months, only minimal atrophic changes were seen on the abdominal CT. She is doing well by maintaining oral anticoagulant therapy and is being followed up regularly through outpatient clinic visits.

Prognostic Factors of the RA Patients with ILD

OBJECTIVE: Interstitial lung disease (ILD) is a common pulmonary manifestation of rheumatoid arthritis (RA), and an important cause of morbidity and mortality in RA. We compared demographic and clinical characteristics of usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) patterns in RA patients and determined the prognostic factors that influence the survival of RA-ILD patients. METHODS: 51 enrolled RA patients (male n=21, female n=30) with ILD underwent HRCT. We categorized ILD into two groups, as the UIP pattern and the NSIP pattern, using HRCT. HRCT scans were scored to investigate the extent of the ILD. We divided the extent of the interstitial lung disease into 4 groups 1~14%, 15~19%, 20~24%, >25%. RESULTS: There were no significant differences between the UIP and NSIP pattern in the clinical characteristics, except for age at the time of the study (RA-NSIP pattern vs RA-UIP pattern 62.3+/-11.7 vs 68.2+/-8.4, p=0.042). There were no significant differences in survival time between the RA-UIP and RA-NSIP pattern (Log rank p=0.985). The extent of ILD on chest HRCT was significantly associated with mortality (HR=1.044, 95% CI 1.019~1.069) and patients that were diagnosed with ILD at an older age (HR=1.109, 95% CI 1.024~1.200) were associated with a worse prognosis. Comparing four groups divided by the extent of the lung disease, there were significant differences in survival estimates (Log-rank p-value<0.001) based on an ILD extent of 15%. CONCLUSION: Our study reveals that the extent of ILD on chest HRCT was found to be significantly associated with poor prognosis of RA-ILD patients.

Remission of Lymphocytic Interstitial Pneumonia in Sjogren's Syndrome after Autologous Peripheral Blood Stem Cell Transplantation

Interstitial pneumonia occurs in approximately 25% of patients with primary Sjogren's syndrome. Interstitial pneumonia combined with primary Sjogren's syndrome usually responds well to systemic steroids, and fatal cases are rare. Lymphocytic interstitial pneumonia shows diffuse infiltration of polyclonal B and T cells. Autologous stem cell transplantation is performed in cases of primary Sjogren's syndrome as an optional treatment when the condition responds poorly to conventional treatment. The hypothesis that primary Sjogren's syndrome improves after transplantation relies on the role of B-cell abnormalities in pathogenesis or the strong effects of immunosuppressive therapy. We experienced the case of a patient diagnosed with primary Sjogren's syndrome and lymphocytic interstitial pneumonia progression refractory to conventional treatment (steroid and immunosuppressive drugs) and cyclophosphamide pulse therapy. Our patient demonstrated improvement of lung manifestations and autoimmune disease activity after autologous stem cell transplantation.

Pandemic H1N1 Influenza Vaccination Responses in Rheumatoid Arthritis and Systemic Lupus Erythematosus Patients

OBJECTIVE: We investigated the efficacy and safety of pandemic H1N1 vaccine in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) patients, and evaluated its correlation with serum cytokine level. METHODS: A total of 43 RA patients and 31 SLE patients were enrolled in the study and were compared with age, sex-matched 40 healthy controls (HC). The blood samples drawn from selected patients before vaccination and in post-vaccination at week 4 were assayed in one session to measure the titers of antibodies against haemagglutinin specific for influenza virus strains: A/California/7/2009 NYMC X-179A (H1N1). Serum IL17 and CXCL13 levels were measured in the same session by enzyme-linked immunosorbent assay. The association of serum cytokine level with anti-influenza antibody titer and mean fold increase (MFI) was investigated. Each specific side effect after vaccination was monitored in both the patients and control groups. RESULTS: The geometric mean antibody titer (GMT) for pre- and post-vaccination at week 4 was not significantly different between RA and HC, SLE and HC. The seroconversion rate in HC and RA was not significantly different, whereas the seroprotection rate is significantly higher in HC (82.5%) than RA (55.8%) (p<0.05). MFI in HC, RA, SLE were 19.65, 6.00 and 6.06, which were significantly higher in HC. Serum IL17 level was 6.28+/-2.89 pg/mL and 7.56+/-3.34 pg/mL in pre-, post-vaccination SLE patients, 33.85+/-15.62 pg/mL and 38.04+/-18.60 pg/mL in RA patients and was significantly lower in SLE patients. Serum CXCL13 level was 518.73+/-720.29 pg/mL and 431.53+/-601.23 pg/mL in pre-, post-vaccination SLE patients, which was significantly higher than HC (149.64+/-248.81 pg/mL and 147.36+/-213.92 pg/mL in each pre-, post-vaccination) and was not significantly different with the level of RA patients. In SLE patients, significant correlations were detected between cytokine level and post-vaccination antibody titer (r=0.22 p=0.026 between IL 17 and GMT; r=0.44, p<0.05 between CXCL13 and GMT). CONCLUSION: The increase in post-vaccination antibody titer is weaker in both RA and SLE patients group than the HC group. Post-vaccination antibody titer was positively correlated with B lymphocyte chemoattractant and CXCL13 in SLE patients, but not in RA patients.
