Plasma Cystatin C Level is a Prognostic Marker of Morbidity and Mortality in Hospitalized Decompensated Cirrhotic Patients.

J Med Invest 2021 ;68(3.4):302-308

Division of Gastroenterology, Department of Internal Medicine, Faculty of Medicine, Thammasat University, Pathumthani, Thailand.

Introduction : Cystatin C (CysC) is biomarker for early detection of acute kidney injury (AKI). However, there is limited evidence in decompensated cirrhotic patients without AKI at admission. This study aimed to assess CysC as a predictor of 90-day mortality. Methods : Decompensated cirrhotic patients without AKI were prospectively enrolled. CysC and creatinine were measured within 24 hours of admission and compared between patients with in-hospital complications (AKI, hepatorenal syndrome (HRS), acute-on-chronic liver failure (ACLF)) vs. those without, and survivors vs. non-survivors. The AUROC and cut-off point of CysC in predicting 90-day mortality were determined. Results : Of 137 decompensated cirrhotic patients, 46 without AKI at admission were included (58.7% male, age 60.8 ± 11.2years, MELD 13.1 ± 5.1, ChildA / B / C 43.5% / 39.1% / 17.4%). The mean CysC level tended to be higher in patients with ACLF (1.52 ± 0.60 vs. 1.11 ± 0.28, p = 0.05), and significantly higher in non-survivors than survivors (1.61 ± 0.53 vs. 1.08 ± 0.28, p = 0.013). The 90-day mortality rate was 21.7%. After adjusting with age and bacterial infection on admission, CysC level  ≥ 1.25 mg / L was significantly associated with 90-day mortality. The CysC cut-off level  ≥ 1.25 mg / L provided 80% sensitivity and 75% specificity for predicting 90-day mortality. Conclusion : Plasma CysC within 24 hours could be used as a predictor for 90-day mortality and development of ACLF in decompensated cirrhotic patients. J. Med. Invest. 68 : 302-308, August, 2021.

Antiviral treatment could not provide clinical benefit in management of mild COVID-19: A Retrospective Experience from Field hospital.

J Infect Public Health 2021 09 31;14(9):1206-1211. Epub 2021 Jul 31.

Chairman of the Executive Committee, Thammasat University Hospital, Pathumthani, Thailand.

Background: Coronavirus disease 2019 (COVID-19) has affected over 145 million infected people and 3 million deaths worldwide. There has been limited data to recommend either for or against use of antiviral regimens in mild COVID-19 patients. This study aimed to compare clinical outcomes between mild COVID-19 patients receiving antiviral drugs and those without.

Method: Thai patients diagnosed with COVID-19 at field hospital affiliated to Thammasat University Hospital, Thailand were evaluated between January 1, 2020 and April 13, 2021. Patients' data, clinical presentation, past medical history, laboratory results, and treatment outcomes were extensively reviewed.

Results: Five hundred patients with positive tests were included in the study. The mean age was 35.9 years; 46% males. There were 225 (45%), 207 (41.4%), 44 (8.8%), 18 (3.6%), 6 (1.2%) patients with asymptomatic, mild, moderate, severe, and critical COVID-19, respectively. Of 207 mild COVID-19 patients, 9 (4.3%) received lopinavir/ritonavir or darunavir/ritonavir, 17 (8.2%) received favipiravir, while 175 (84.5%) had only supportive care. Mild COVID-19 patients receiving antiviral treatment had longer median length of hospital stay [13 days (IQR 11-14) vs. 10 days (IQR 8-12), p < 0.001] than patients having only supportive treatment. Antiviral drug use was significantly associated with longer hospital stay (>10 days) in mild COVID-19 patients (OR 5.52; 95%CI 2.12-14.40, p < 0.001). Adverse drug reactions such as diarrhea, abdominal pain, and hepatitis were also demonstrated in our COVID-19 patients with antiviral treatments. Majority of patients (97.6%) recovered without any complications and were discharged home. Two deaths were caused by acute respiratory distress syndrome from severe COVID-19 pneumonia.

Conclusion: Antiviral treatment could not provide superior clinical outcomes to supportive care in mild COVID-19 patients. Mild COVID-19 patients receiving antiviral medication had longer length of hospital stay than those without. Standard supportive care and regular monitoring of disease progression might be keys for successful management of mild COVID-19.

Predictors for regression and progression of intestinal metaplasia (IM): A large population-based study from low prevalence area of gastric cancer (IM-predictor trial).

PLoS One 2021 11;16(8):e0255601. Epub 2021 Aug 11.

Department of Environmental and Preventive Medicine, Faculty of Medicine, Oita University, Yufu, Japan.

Background: Gastric intestinal metaplasia (IM) can lead to gastric cancer. Until now, there have been limited studies of predictors for regression and progression of IM. This study aimed to determine risk factors associated with regression or progression of IM for guiding proper management and prevention of gastric cancer.

Methods: 2,025 patients undergoing gastroscopy in Thammasat University Hospital, Thailand were enrolled during September 2017-August 2019. Patients' data including baseline characteristics, laboratory results, and histopathology of gastric biopsies from University medical database were extensively reviewed.

Results: 2,025 patients had mean age of 61.3 years and 44.2% were males. Overall H. pylori prevalence was 47.5%. There were 1,551(76.6%) patients with chronic gastritis and 361(17.8%) with IM. Of 400 patients with chronic gastritis having follow-up endoscopy and repeated gastric biopsies, 104(26%) had persistent H. pylori infection and 27(26%) developed IM during mean follow-up time of 24 months. Persistent H. pylori infection was significantly associated with development of IM (OR 3.16, 95%CI 1.56-6.39, p = 0.001). Regression, persistence, and progression of IM were demonstrated in 57.3%, 39.2%, and 3.5% of patients, respectively. Age >65 years, persistent H. pylori infection, and diabetes mellitus were significantly associated with persistent IM or progression to dysplasia with OR 2.47(95%CI 1.33-4.61, p = 0.004), OR 2.64(95%CI 1.13-6.18, p = 0.025), and OR 2.54(95%CI 1.16-5.54, p = 0.019), respectively. Patients without H. pylori infection had more IM regression than patients with persistent infection (60.4%vs.39.4%, p = 0.035). Patients with persistent H. pylori infection significantly had higher IM progression to dysplasia (15.2%vs.2.1%; OR 11.15, 95%CI 1.18-105.24, p = 0.035) than noninfected. During 24 months of study, 30 patients (1.5%) were diagnosed with gastric cancer.

Conclusion: Regression of IM could be achieved by successful H. pylori eradication. Persistent H. pylori infection was significantly associated with development and progression of IM to dysplasia. Age >65 years and diabetes mellitus were also significant predictors for IM progression.

Clinical Features and Overall Survival of Females with Hepatocellular Carcinoma: A Retrospective Study and Review of the Literature in the Association of Southeast Asian Nations.

Int J Womens Health 2021 22;13:717-725. Epub 2021 Jul 22.

Department of Medicine, Chulabhorn International College of Medicine (CICM) at Thammasat University, Pathumthani, Thailand.

Introduction: Hepatocellular carcinoma (HCC) causes more than 200,000 women deaths annually. This study aimed to investigate the clinical features, provide prognostic factors for female patients with HCC, and performed a literature review on them in the Association of Southeast Asian Nations (ASEAN).

Materials And Methods: We conducted a retrospective cohort study of female patients with HCC at Thammasat University Hospital, Thailand between January 2009 and January 2019. Furthermore, important aspects of female patients with HCC in the ASEAN published in PubMed and Scopus up to October 2020 were extensively reviewed.

Results: A total of 187 female patients with HCC were included (mean age 65.7±11.9 years). Elderly females were diagnosed with HCC at a more advanced stage than younger individuals (37.0% vs 23.2%, p=0.049, OR 1.94, 95% CI 1.00-3.78) and the younger group had a significantly higher overall 2-year survival rate than the elderly group (65.0% vs 45.5%, p=0.03, OR 2.23, 95% CI 1.09-4.57). Abdominal pain (HR 9.89, 95% CI 2.85-34.38, p<0.001), ascites at presentation (HR 2.77, 95% CI 1.11-6.92, p=0.03), ruptured hepatoma (HR 14.68, 95% CI 12.60-83.09, p=0.002), advanced-stage HCC (HR 9.74, 95% CI 1.89-50.26; p=0.007), and serum hypoalbuminemia (HR 4.67, 95% CI 1.62-13.50, p=0.004) were significantly associated with poor survival rate. From the ASEAN, a total of 543 females HCC patients from 6 studies were extensively reviewed. Chronic hepatitis B infection was among the pre-existing liver disease leading to HCC in ASEAN. HCC in females of the ASEAN occurred most often at an advanced age and had a grave prognosis.

Conclusion: HCC affects a large number of females, especially in Thailand and the ASEAN, is diagnosed at an advanced stage and had a grave prognosis. Abdominal pain, ascites, ruptured HCC, advanced-stage HCC, and serum hypoalbuminemia are associated with poor prognosis. Early detection of HCC and prompt treatment in patients at risk could result in better survival outcomes.

Gastrointestinal manifestation as clinical predictor of severe COVID-19: A retrospective experience and literature review of COVID-19 in Association of Southeast Asian Nations (ASEAN).

JGH Open 2020 Dec 12;4(6):1096-1101. Epub 2020 Sep 12.

Gastroenterology Unit, Department of Medicine, Faculty of Medicine Thammasat University Hospital Khlong Nueng Thailand.

Background And Aim: Coronavirus disease 19 (COVID-19) has caused over 200 000 deaths worldwide. Thailand announced the first confirmed case outside mainland China in January 2020. The disease also spread widely across Association of Southeast Asian Nations (ASEAN). Gastrointestinal manifestations could be presenting symptoms of COVID-19. This study aimed to determine the prevalence of gastrointestinal manifestations of COVID-19 patients in Thailand and review important aspects of this disease in ASEAN.

Methods: Thai patients diagnosed with COVID-19 at Thammasat University Hospital, Thailand, were evaluated between 1 January 2020 and 30 April 2020. Patients' data, clinical presentation, exposure risk, past medical history, laboratory results, and treatment outcomes were extensively reviewed.

Results: A total of 352 COVID-19 tests were performed, and 40 patients with positive tests were studied. The mean age was 30.5 years, and 55% were female. Most (82.5%) had no underlying diseases. Comorbidities were associated with severe COVID-19 (odds ratio [OR] 29.93; 95% confidence interval [CI] 2.31-388.40, = 0.009). Gastrointestinal symptoms were present in 12 patients (30%). The most common presenting symptoms were anorexia (17.5%) and diarrhea (15%). Gastrointestinal symptoms developed before (9.1%), concurrent with (63.6%), and after (27.3%) respiratory symptoms. Diarrhea was significantly associated with severe COVID-19 (OR 38.52; 95% CI 3.11-476.70, = 0.004). Twenty-four patients (60%) received antiviral drugs; 40% had only supportive care. Only one patient required intensive care. No patient died.

Conclusions: Gastrointestinal manifestations in COVID-19 patients are common symptoms and can occur anytime during the disease course. Patients presenting with only gastrointestinal symptoms should raise clinical suspicion for COVID-19 in areas with high disease incidence. Clinically severe COVID-19 was associated with comorbidities and diarrhea.

Prognostic factors for survival in patients with gastric adenocarcinoma.

Cancer Rep (Hoboken) 2021 02 19;4(1):e1305. Epub 2020 Oct 19.

Gastroenterology Unit, Thammasat University Hospital, Pathumthani, Thailand.

Background: Gastric cancer ranks as a leading cause of cancer deaths worldwide. Information of prognostic factors related to gastric cancer are limited.

Aim: This study aimed to gather clinical data and prevalence of prognostic factors related to gastric adenocarcinoma in Thailand.

Methods And Results: This retrospective cohort study was conducted at Thammasat University Hospital, Thailand between January 2010 and July 2018. Gastric adenocarcinoma patients were enrolled and followed up for at least 5 years. Total of 210 gastric tumor patients were enrolled. One hundred patients were diagnosed with gastric adenocarcinomas (57 men and 43 women, mean age = 61.1 years). The leading presenting symptoms were weight loss (65%), followed by dyspepsia (54%) and UGI bleeding. Common clinical manifestations were thrombocytosis (26%), followed by syndrome of inappropriate antidiuretic hormone (SIADH; 15%). Eosinophilia was present in early cancer (25.0% vs 6.5%, P = .123), while SIADH and thrombocytosis were more common in advanced stages (16.3% vs 0%, P = .602, and 28.3% vs 0%, P = .108, respectively). SIADH was significantly related to reduced 1-year survival rate compared to normal serum sodium levels (21.4% vs 71.4%, OR 0.109, 95% CI 0.024-0.497, P = .004). Five-year survival rates were worse in patients with SIADH, but better in patients with eosinophilia compared to patients without these conditions (0% vs 27.8%, P = .058 and 20.0% vs 7.8%, P = .375, respectively).

Conclusion: Thrombocytosis and SIADH were common in gastric cancer. SIADH was significantly correlated with poor 1-year survival. These clinical manifestations might be useful for predicting gastric cancer prognosis.

Predictors for development of complete and incomplete intestinal metaplasia (IM) associated with H. pylori infection: A large-scale study from low prevalence area of gastric cancer (IM-HP trial).

PLoS One 2020 1;15(10):e0239434. Epub 2020 Oct 1.

Digestive Diseases Research Center (DRC), Thammasat University Hospital, Pathumthani, Thailand.

Background: Gastric intestinal metaplasia (IM) is precancerous lesion of gastric cancer related to H. pylori infection. There has been limited data about IM and associated risk factors. This study aimed to determine risk factors related to development of IM to guide proper management.

Methods: 1,370 patients undergoing UGI endoscopy at Thammasat University Hospital, Thailand were included between January 2018-August 2019. Patients' data including baseline characteristics, laboratory results, and histopathology from medical database were extensively reviewed. Immunohistochemical staining for p53 expression from gastric biopsies was also performed.

Results: Overall H. pylori prevalence was 43.8%. Mean age was 60.7 years and 45% of whom were males. Chronic gastritis was observed in 1,064(77.7%) patients, while 223(16.3%) had IM. Of 223 patients with IM, 194(87%) patients had complete IM, while 29 (13%) had incomplete IM. In groups of complete and incomplete IM, current H. pylori infection rates were 66.5% and 58.6%, respectively. The BMI of incomplete IM group(27.4) was significantly higher than BMI of complete IM group (23.6). Overweight and obese patients (BMI ≥23 kg/m2) were significantly associated with higher risk for the development of incomplete IM (OR 3.25; 95%CI 1.14-9.27, p = 0.027). Males, age >50 years, and current H. pylori infection were significantly higher in IM than chronic gastritis group with OR 1.43 (95%CI 1.01-2.03, p = 0.048), OR 1.67 (95% CI 1.08-2.57, p = 0.021), and OR 3.14 (95% CI 2.29-4.30, p<0.001), respectively. During 20 months of study, there were 15 patients (1.1%) diagnosed with gastric cancer and 1-year survival rate was only 60%.

Conclusions: Males, age >50 years, and current H. pylori infection are significant predictors for the presence of intestinal metaplasia. BMI might be beneficial for using as a predictive risk factor to reduce the development of incomplete intestinal metaplasia. H. pylori eradication could be an effective way to prevent the development of gastric precancerous lesions.

Population-based study of Helicobacter pylori infection and antibiotic resistance in Bhutan.

Int J Infect Dis 2020 Aug 29;97:102-107. Epub 2020 May 29.

Department of Environmental and Preventive Medicine, Oita University Faculty of Medicine, Yufu, Japan.

Objectives: Bhutan suffers from a high prevalence of Helicobacter pylori (H. pylori) infection and gastric cancer-related mortality. In preparation for a countrywide H. pylori eradication program, the antibiotic resistance patterns of H. pylori infection were surveyed in different geographical regions.

Methods: Dyspeptic patients in 6 districts including Thimphu, Punakha, Wangdue, Trongsa, Bumthang, and Haa underwent upper gastrointestinal endoscopy during GASTROCAMP and were enrolled between December 2010 and April 2015. Gastric biopsies were obtained for rapid urease test, histopathology, and H. pylori culture. Antimicrobial susceptibility testing was later performed if the culture was positive.

Results: A total of 1178 patients were surveyed. The overall H. pylori infection in Bhutan was 66.2%. Punakha had the highest prevalence of H. pylori infection (85.6%). Thimphu and Punakha (city areas) had higher prevalence of H. pylori infection than rural districts (73.5% vs 63.3%, OR=1.61, 95% CI 1.22-2.13, p=0.0008). There were 357 patients (30.3%) with positive H. pylori culture completed antimicrobial susceptibility testing. The mean age was 40.5 years with female predominance (57.1%). No amoxicillin resistant strains were found. Metronidazole resistance was 81% followed by levofloxacin resistance (8.1%). Clarithromycin (2%) and tetracycline (0.6%) resistance was rare except in Thimphu, the capital city (10%) vs 0% in rural areas, p<0.001. The metronidazole resistance rate remained stable at approximately 80% during the past 5 years of study. Levofloxacin-resistant strains gradually rose from 5.3% in 2010 to 9.9% in 2015.

Conclusions: Bhutan had a high prevalence of H. pylori infection. Metronidazole resistance was extremely high, whereas clarithromycin resistance was quite low in this specific area. Antibiotic resistance pattern could be good evidence for guiding a proper treatment regimen for H. pylori infection in Bhutan.

Prevalence and Antibiotic Resistance Patterns of Helicobacter pylori Infection in Koh Kong, Cambodia.

Asian Pac J Cancer Prev 2020 May 1;21(5):1409-1413. Epub 2020 May 1.

Department of Environmental and Preventive Medicine, Oita University Faculty of Medicine, Yufu, Japan.

Background: Gastric cancer, which is the leading cause of cancer mortality in Cambodia, can be prevented by Helicobacter pylori (H. pylori) eradication. There is limited data about H. pylori strains in Cambodia. This study aimed to evaluate H. pylori prevalence and antibiotic resistance in Koh Kong, Cambodia.

Methods: 118 Cambodian dyspeptic patients were scheduled to enter this study and 58 were enrolled between July and September 2019. All patients underwent upper GI endoscopy. 3 gastric biopsies were obtained for rapid urease test, H. pylori culture with E-test and GenoType® HelicoDr (Hain Lifescience factory, Germany). 3-mL blood sample was collected for CYP2C19 genotyping.

Results: 58 subjects were enrolled (40 females, 18 males, mean age 43.8 years). Overall H. pylori prevalence was 31.0%. Antibiotic resistance rates were 78.6% for metronidazole, 50.0% for fluoroquinolones, and 27.8% for clarithromycin. There was no amoxicillin and tetracycline resistance. More than half of H. pylori strains (57.1%) were multidrug-resistant. Most (35.7%) were resistant to metronidazole and quinolone. Poor, intermediate and rapid metabolizers were 5.5%, 38.9% and 55.6%, respectively.

Conclusions: H. pylori infection remains common infection in Cambodia. High prevalence of clarithromycin, metronidazole, levofloxacin and multidrug-resistant H. pylori is still major problems in Cambodia. Treatment regimens without clarithromycin and quinolone such as 14-day bismuth-based quadruple therapy might be an appropriate choice for H. pylori eradication in this particular area.

Efficacy of Omeprazole, Tetracycline, and 4 Times Daily Dosing of Amoxicillin in Helicobacter pylori Eradication in Limited Resource Area in Bhutan: A Prospective Randomized Trial (BHUTAN Study).

Asian Pac J Cancer Prev 2020 Apr 1;21(4):1109-1114. Epub 2020 Apr 1.

Department of Environmental and Preventive Medicine, Oita University Faculty of Medicine, Yufu, Japan.

Backgrourd: H. pylori-associated gastric cancer is the first cancer-related death in Bhutan. Effective regimen for H. pylori eradication is essential to reduce risk of developing gastric cancer. Clarithromycin is not widely used in this limited resource country. Aim of this study was to evaluate proper regimen and prevalence of antibiotic resistance pattern for H. pylori eradication in Bhutan.

Methods: Five hundred and forty-six patients underwent gastroscopy during GASTROCAMP between October 2014 and April 2015 in Bhutan and 77 patients were enrolled. Four gastric biopsies were obtained for rapid urease test, histopathology, H. pylori culture with Epsilometer test. All H. pylori-positive patients were randomized to receive either 7-day or 14-day of 500 mg amoxicillin four times daily, 500 mg tetracycline four times daily, and 20 mg omeprazole twice daily.

Results: Seventy-seven subjects were enrolled (54 females, 23 males, mean age = 45.4 years). Of 77 patients, 52 (67.5%) received 7-day regimen while 25 (32.5%) had 14-day regimen. Prevalence of H. pylori was 38.2%. Antibiotic resistance was 80.0% for metronidazole, 11.1% for levofloxacin and no resistance seen in amoxicillin, tetracycline and clarithromycin. Overall eradication rates of 7-day and 14-day regimens were 51.9% and 80.0%, p = 0.02. Female and age ≥40 years had significantly higher eradication rate when receiving 14-day compared to 7-day regimen (94.1% vs. 45.9%, OR = 18.82; 95% CI 2.26-157.02, p = 0.0007 and 86.7% vs. 50.0%, OR = 6.50; 95% CI 1.25-33.91, p = 0.02, respectively).

Conclusions: Fourteen-day regimen might be an acceptable regimen for H. pylori eradication in limited resource area such as Bhutan. Female and age ≥40 years should receive longer duration of treatment. This 14-day regimen could at least reduce the risk of developing H. pylori-associated diseases especially peptic ulcer with complications and gastric cancer which lead to many deaths in Bhutan.

High Efficacy of Rapid Urine Test for Diagnosis of Helicobacter pylori Infection in Thai People

Asian Pac J Cancer Prev 2019 May 25;20(5):1525-1529. Epub 2019 May 25.

Digestive Diseases Research Center of Thailand, Pathumthani, Thailand.

Background: Accurate diagnosis of Helicobacter pylori (H. pylori) infection plays an important role in further effective treatment. Rapid urine test (RAPIRUN) is a test developed for qualitative detection of urine H. Pylori antibody and use for determine the sensitivity, specificity and accuracy. However, the test needs validation in Thai population before using in clinical practice. Objective: This study aimed to compare performance of different diagnostic tests on H. pylori detection in Thai population. Methods: Total of 94 patients with dyspepsia who referred to Thammasat University Hospital, Pathumthani, Thailand, between December 2012 and April 2013 were enrolled in this study. All patients underwent gastroscopy. Then, 3 biopsies at antrum were taken for H. pylori diagnosis. including rapid urease test (Pronto Dry, Eisai, Thailand), H. pylori culture, and histopathology. Urine samples were also collected at the same time for rapid urine test (RAPIRUN H. pylori Antibody, Otsuka Pharmaceutical Co., Ltd.). Patients were diagnosed with H. pylori-positive if their culture or rapid urease tests plus histopathology yielded positive results. Results: Total of 29 patients (30.9%) were infected with H. pylori. Prevalence of H. pylori infection by rapid urease test, histopathology, culture and rapid urine test were 25.5%, 28.7%, 29.8%, and 32.9% respectively. We observed that rapid urease test, histopathology, culture, and rapid urine test had sensitivity of 82.8%, 93.1%, 93.1% and 86.2%; specificity of 100%, 100%, 100%, and 90.8%; and accuracy of 95.7%, 97.9%, 97.9%, and 89.4%, respectively. Conclusion: Rapid urine test (RAPIRUN) provided a reliable result for diagnosis of H. pylori infection. Furthermore, this rapid urine test demonstrated high accuracy, reliable, safe handle and easy to use. We suggested rapid urine test for diagnosis of H. pylori infection in Thai population since we found it less invasive and with higher reliable efficacy.
