RESUMO

BACKGROUND: We aimed to evaluate the interaction between colorectal adenoma risks among asymptomatic individuals in terms of metabolic health status and obesity, and examine the normal waist-to-hip ratio (WHR) in adults with colorectal adenoma risk. METHODS: A cross-sectional, retrospective study was conducted at MacKay Memorial Hospital involving 16,996 participants who underwent bidirectional gastrointestinal endoscopy between 2013 and 2023. The study recorded important clinicopathological characteristics, including age, body mass index and WHR, Framingham Risk Score (FRS), blood glucose level, and Helicobacter pylori (H. pylori) infection status. RESULTS: Multivariate logistic regression analysis demonstrated that elevated hemoglobin A1C (HbA1c), increased FRS, positive H. pylori infection, and WHR ≥ 0.9 are independent risk factors for colorectal adenoma. In examining the interaction between FRS and WHR using multivariate logistic regression to evaluate adenoma risk, the OR for the interaction term was 0.95, indicating a decline in adenoma risk when considering the interaction between these two factors. Incorporating HbA1c into the analysis, evaluating the interaction between FRS and WHR still demonstrated a statistically significant impact on adenoma risk (OR 0.96, p < 0.001). Participants with WHR < 0.9, elevated FRS, positive H. pylori infection, and increased HbA1c levels were associated with a higher risk of colorectal adenoma formation. Remarkably, the increased risk of adenoma due to rising HbA1c levels was statistically significant only for those with a WHR < 0.9. CONCLUSIONS: An increase in FRS and HbA1c or a positive H. pylori infection still warrants vigilance for colorectal adenoma risk when WHR is 0.9. These factors interacted with each other and were found to have a minimal decline in adenoma risk when considering the interaction between WHR and FRS.

RESUMO

Helicobacter pylori (H. pylori) has infected approximately fifty percent of humans for a long period of time. However, improvements in the public health environment have led to a decreased chance of H. pylori infection. However, a high infection rate is noted in populations with a high incidence rate of gastric cancer (GC). The worldwide fraction of GC attributable to H. pylori is greater than 85%, and a high H. pylori prevalence is noted in gastric mucosa-associated lymphoid tissue lymphoma patients. These results indicate that the majority of GC cases can be prevented if H. pylori infection is eliminated. Because H. pylori exhibits oral-oral or fecal-oral transmission, the relationship between this microorganism and other digestive tract malignant diseases has also attracted attention. This review article provides an overview of H. pylori and the condition of the whole gastrointestinal tract environment to further understand the correlation between the pathogen and the host, thus allowing improved realization of disease presentation.

RESUMO

BACKGROUND: Helicobacter pylori infection and hyperglycemia are associated with an increased risk of colorectal neoplasm, and may have a synergistic effect in combination. However, these 2 factors that affect colorectal neoplasm remain controversial. We aimed to carry out a meta-analysis to evaluate the study population diabetes prevalence rate and H pylori infection rate with colorectal adenoma risk for adults. METHODS: We conducted systemic research through English databases for medical reports. We also recorded the diabetes prevalence and H pylori infection prevalence in each study. We classified these studies into 4 subgroups as their background population diabetes prevalence <6% (Group 1); between 6% and 8% (Group 2); between 8% and 10% (Group 3), and more than 10% (Group 4). The random-effects model had used to calculate pooled prevalence estimates with 95% confidence interval (CI). RESULTS: Twenty-seven studies were finally eligible for meta-analysis. The random-effects model of the meta-analysis was chosen, showing pooled odds ratio (OR) equal to 1.51 (95% CI 1.39-1.63). The subgroup meta-analyses showed in Group 1 the H pylori infection associated colorectal adenoma risk OR was 1.24 (95% CI 0.86-1.78). As the diabetes rate exceed 6%, the H pylori infection became the more significant increased risk of colorectal adenoma (Group 2: OR 2.16 (95% CI 1.61-2.91); Group 3: OR 1.40 (95% CI 1.24-1.57); and Group 4: OR 1.52 (95% CI 1.46-1.57)). CONCLUSIONS: The results of this meta-analysis showed elevated diabetes prevalence combined H pylori infection increasing the risks of colorectal adenoma in the adult population.

RESUMO

FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin), a 5-fluorouracil (5-FU)-based chemotherapy regimen, is one of most common therapeutic regimens for colorectal cancer. However, intestinal mucositis is a common adverse effect for which no effective preventive strategies exist. Moreover, the efficacy and the safety of fecal microbiota transplants (FMT) in cancer patients treated with anti-neoplastic agents are still scant. We investigated the effect of FMT on FOLFOX-induced mucosal injury. BALB/c mice implanted with syngeneic CT26 colorectal adenocarcinoma cells were orally administered FMT daily during and two days after five-day injection of FOLFOX regimen for seven days. Administration of FOLFOX significantly induced marked levels of diarrhea and intestinal injury. FMT reduced the severity of diarrhea and intestinal mucositis. Additionally, the number of goblet cells and zonula occludens-1 decreased, while apoptotic and NF-κB-positive cells increased following FOLFOX treatment. The expression of toll-like receptors (TLRs), MyD88, and serum IL-6 were upregulated following FOLFOX treatment. These responses were attenuated following FMT. The disrupted fecal gut microbiota composition was also restored by FMT after FOLFOX treatment. Importantly, FMT did not cause bacteremia and safely alleviated FOLFOX-induced intestinal mucositis in colorectal cancer-bearing mice. The putative mechanism may involve the gut microbiota TLR-MyD88-NF-κB signaling pathway in mice with implanted colorectal carcinoma cells.

RESUMO

Neutrophil-to-lymphocyte ratio (NLR) serves as a strong prognostic indicator for patients suffering from various diseases. Neutrophil activation promotes the recruitment of a number of different cell types that are involved in acute and chronic inflammation and are associated with cancer treatment outcome. Measurement of NLR, an established inflammation marker, is cost-effective, and it is likely that NLR can be used to predict the development of metabolic syndrome (MS) at an early stage. MS scores range from 1 to 5, and an elevated MS score indicates a greater risk for MS. Monitoring NLR can prevent the risk of MS.A total of 34,013 subjects were enrolled in this study. The subjects (score 0-5) within the 6 groups were classified according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria, and all anthropometrics, laboratory biomarkers, and hematological measurements were recorded. For the 6 groups, statistical analysis and receiver operating characteristic (ROC) curves were used to identify the development of MS.Analysis of the ROC curve indicated that NLR served as a good predictor for MS. An MS score of 1 to 2 yielded an acceptable discrimination rate, and these rates were even higher for MS scores of 3 to 5 (P < .001), where the prevalence of MS was 30.8%.NLR can be used as a prognostic marker for several diseases, including those associated with MS.

RESUMO

Atherosclerosis has severe consequences on human health. Carotid artery plaques are a condition typically caused by atherosclerosis. Previous studies showed that nonalcoholic fatty liver disease (NAFLD) and Helicobacter pylori (H pylori) are risks factors for carotid artery plaque formation. We hypothesize that the combination of NAFLD with H pylori infection increases the risk of carotid artery plaque formation.A total of 4669 subjects aged > 40 years who underwent routine health checkups between January 2006 and December 2015 were retrospectively reviewed. A serial examination, including abdominal ultrasound, carotid artery ultrasound and esophago-gastroduodenoscopy (EGD), and biopsy urease testing, was conducted.In total, 2402 subjects were enrolled. There were no differences in H pylori infection status among patients with or without NAFLD. There was a trend of more participants with both NAFLD and H pylori infection (number [N]=583) presenting carotid artery plaque (N = 187,32.08%) than participants without NAFLD and H pylori infection (N = 589) who presented plaque formation (N = 106, 18.00%). Participants who had both H pylori infection and NAFLD had the highest risk of any carotid artery plaque (odds ratio [OR], 1.93; 95% confidence interval [CI], 1.413-2.636) based on a multivariate logistic regression analysis. This analysis also showed that age >60 years, male sex, low-density lipoprotein (LDL) >130 mg/dL, and H pylori infection were independent risk factors for concomitant NAFLD and carotid artery plaque formation.The combination of H pylori infection and NAFLD increases carotid artery plaque formation. H pylori eradication and NAFLD control may be warranted to prevent carotid artery plaque formation.

RESUMO

BACKGROUND AND AIM: Several strategies have been proposed to increase the eradication rate of Helicobacter pylori. However, the widespread increasing resistance rates to current multiple-dose oral antibiotic therapies call for alternative therapeutic approaches. We aim to develop a novel intraluminal therapy for H. pylori infection (ILTHPI). METHODS: From April 2017 to December 2017, 100 H. pylori-infected treatment-naïve patients with upper abdominal pain or discomfort underwent endoscopic examinations and concomitant ILTHPI, which comprised the control of intragastric pH, the irrigation of gastric mucosal surface with a mucolytic agent, and the application of single-dose medicaments containing antibiotic powders. The safety profiles while conducting ILTHPI and adverse events after ILTHPI were evaluated. The success of eradication was assessed based on the result of the 13 C-urea breath test 6 weeks after ILTHPI. In addition, a patient with successful ILTHPI was reconfirmed by a negative H. pylori stool antigen test four to 6 months after ILTHPI to exclude short-term recurrence. RESULTS: All the 100 enrolled patients completed the ILTHPI with good safety profiles and mild adverse events (6%). Five patients dropped out, and 51 of 95 patients (53.7%) achieved successful eradication immediately after endoscopic examinations. All 51 patients revealed negative stool H. pylori antigen tests four to 6 months after successful ILTHPI. No short-term recurrence was observed. CONCLUSIONS: We have developed a novel therapeutic approach. With the ILTHPI, H. pylori can be eradicated immediately by administrating a single-dose regimen while conducting an endoscopic examination. CLINICAL TRIALS NUMBER: NCT03124420.

RESUMO

Nucleos(t)ide analogs are used for preventing liver cirrhosis in chronic hepatitis B patients, but the risk factors of hepatocellular carcinoma (HCC) in these patients remain unclear. We designed this retrospective cohort study, the aim is to determine the risk factors for HCC development and its image presentation under nucleos(t)ide analogs treatment.In this study, patients were treated with lamivudine (LAM), entecavir 0.5 mg (ETV), or telbivudine (LdT), and followed-up for at least 2 years to detect HCC and its presentation. Assessment of the risk factors for HCC included age, sex, HBeAg, viral load, liver cirrhosis, current and previous medications, and liver function tests.Totally, 396 patients were recruited, and 18 patients developed HCC. The mean time from the treatment to HCC development was 28.5 ±â€Š16.7 months. The clinical characteristics in HCC and no-HCC groups showed significant differences among age (52.8 ±â€Š6.1 vs 47.1 ±â€Š12.6 years, P <.01), baseline alanine transaminase (ALT) levels (161.4 ±â€Š177.3 vs 361.7 ±â€Š496.3, P <.01), and baseline liver cirrhosis (72.2% vs 29.9%, P <.01). In patients aged ≥45 years, the hazard ratio of HCC was 10.2 and liver cirrhosis was 4.1. Majority of HCCs developed in the right liver (14/18), were single numbered (13/18), had tumor size about 1.9 ±â€Š0.7 cm, were classified as T1 (14/18, TNM staging), and the atypical image occupied 88% of the HCC cases.The patients aged ≧45 years on long-term nucleos(t)ide analog therapy, and with baseline liver cirrhosis were at a high risk of HCC. Regular alpha-fetoprotein (AFP) assessment and image study of these patients are the gold standards for early HCC detection in patients with high percentage atypical HCC appearances.

RESUMO

BACKGROUND: Clinical characteristics and risk factors for mortality of Acinetobacter bacteremia in cirrhotic patients have not been investigated. METHODS: Acinetobacter bacteremia cases from four medical centers were collected from 2009 to 2014, to compare between patients with and without liver cirrhosis. Risk factors for mortality of Acinetobacter bacteremia among cirrhotic patients were identified using multivariate logistic regression. RESULTS: Among the patients with Acinetobacter bacteremia, 72 had liver cirrhosis and 816 had not. Patients with cirrhosis were younger (57.5 [50-71] vs. 72 [50.25-71], p < 0.001), had more solid tumor (51.4% vs. 31.4%, p = 0.001), lower Acute Physiology and Chronic Health Evaluation II (APACHE II) scores (17 [12-24] vs. 20 [13-28], p = 0.012), less sourced from pneumonia (19.4% vs. 35.8%, p = 0.008), and less caused by Acinetobacterbaumannii (33.3% vs. 50.6%, p = 0.007) than those without. After matching for age, sex, and causative pathogens, the 30-day mortality (34.7% vs. 29.2%, p = 0.592) and APACHE II scores (17 vs. 17, p = 0.769) were not significant. APACHE II score (odds ratio [OR], 1.146; 95% confidence interval [CI], 1.035-1.268; p = 0.009), bacteremia caused by A. baumannii (OR, 20.501; 95% CI, 2.301-182.649; p = 0.007), and solid tumor (OR, 18.073; 95% CI, 1.938-168.504; p = 0.011) were independent risk factors for 30-day mortality of cirrhotic patients with Acinetobacter bacteremia. CONCLUSION: Even though cirrhotic patients with Acinetobacter bacteremia were younger and had lower APACHE II scores than non-cirrhotic patients, the mortality rates were insignificantly different between the two groups.

RESUMO

BACKGROUND: Helicobacter pylori infection is associated with colorectal adenoma and confers a 1.3- to 2.26-fold increased risk. We evaluated the association between H. pylori and the progression of colorectal adenoma. METHODS: This retrospective cohort study included 615 adults with no history of colorectal adenoma or cancer at baseline who participated in a repeated, regular health screening examination, which included a bidirectional gastrointestinal endoscopy, between July 2006 and June 2015. A gastric biopsy specimen from each subject was tested for H. pylori. RESULTS: During follow-up, the incidence rates of colorectal adenoma progression in participants with persistent H. pylori infections (persistent group) and those whose infections had previously been successfully eradicated (eradication group) were 160.52 and 51.60 per 1000 person-years, respectively (P = .0003). After adjustment for confounding factors, the persistent group exhibited a higher risk of colorectal adenoma than the eradication group (hazard ratio = 3.04, 95% CI 1.899, 5.864). The colorectal adenoma ratio of patients uninfected with H. pylori was similar to that of the eradication group (23.93% vs 20.12%, P = .328). CONCLUSIONS: Persistent H. pylori infection was associated significantly with the independent development of colorectal adenoma. H. pylori infection may have a pathophysiological role in colorectal adenoma development and, after successful eradication of H. pylori, the colorectal adenoma ratio might decrease.

RESUMO

BACKGROUND: The overlapping symptoms and pathophysiological similarities between burn injury and chronic fatigue syndrome (CFS) are noteworthy. Thus, this study explores the possible association between burn injury and the subsequent risk of CFS. METHOD: We used data from the Taiwan National Health Insurance system to address the research topic. The exposure cohort comprised of 17,204 patients with new diagnoses of burn injury. Each patient was frequency matched according to age, sex, index year, and comorbidities with four participants from the general population who did not have a history of CFS (control cohort). Cox proportional hazards regression analysis was conducted to estimate the relationship between burn injury and the risk of subsequent CFS. RESULT: The incidence of CFS in the exposure and control cohorts was 1.61 and 0.86 per 1000 person-years, respectively. The exposure cohort had a significantly higher overall risk of subsequent CFS than did the control cohort (adjusted hazard ratio [HR] = 1.48, 95% confidence interval [CI] = 1.41-1.56). The risk of CFS in patients with burn injury in whichever stratification (including sex, age, and comorbidity) was also higher than that of the control cohort. CONCLUSION: The findings from this population-based retrospective cohort study suggest that thermal injury is associated with an increased risk of subsequent CFS and provided a point of view suggesting burn injuries in sun- exposed areas such as the face and limbs had greater impact on subsequent development of CFS compared with trunk areas. In addition, extensively burned areas and visible scars were predictors of greater physiological and psychosocial that are needed to follow-up in the long run.

RESUMO

BACKGROUND AND AIM: To assess the detection rates of Helicobacter pylori colonization in the gastric cardia with two commercial kits of rapid urease test: 5 min UFT300 and 24 h CLO test in H. pylori-infected patients. METHODS: Eighty consecutive dyspeptic patients with confirmed H. pylori infection (serology and 13C-urea breath test) were prospectively studied. During endoscopy, tissue samples using separate biopsy forceps from the cardia were taken for the UFT300 and CLO tests. The results of the UFT300 were read at 5 and 30 min, and those of the CLO test were read at 24 h. RESULTS: Of 80 enrolled patients, 17 (21.3%) and 44 (55%) had positive findings with the UFT300 at 5 and 30 min, respectively, while 72 (90%) had positive findings with the CLO test at 24 h. The CLO test is significantly more sensitive than the UFT300 in evaluating H. pylori status in the cardia. On comparing patients with and without carditis, the detection rates of the CLO test were similar (91.1% vs 88.6%; P = 0.724), and the rates of the UFT300 were also similar at 5 and 30 min. CONCLUSIONS: The rate of H. pylori colonization in the gastric cardia was 90% in H. pylori-infected patients detected with the CLO test. Although the UFT300 provides a more rapid reading of H. pylori status, the diagnostic yield of the CLO test is much higher than that of the UFT300. However, a positive result of the UFT300 may indicate a higher bacterial load in the cardia, which warrants a more effective therapeutic strategy.

RESUMO

Adjuvant 5-fluorouracil (5-FU)-based chemotherapy, including FOLFOX (5-FU, leucovorin, and oxaliplatin), is recommended for colorectal cancer. However, intestinal mucositis remains a common adverse effect for which no effective preventive strategies are available. To develop a convenient and novel way to alleviate mucositis, we investigated the effect of Lactobacillus casei variety rhamnosus (Lcr35) on FOLFOX-induced mucosal injury. BALB/c mice subcutaneously injected with syngeneic CT26 colorectal adenocarcinoma cells were orally administered Lcr35 daily before, during, and after 5-day injection of FOLFOX regimen, for 14 days. The following methods were used: diarrhea score for toxicity, ELISA for cytokine production, histopathology for intestinal injury, immunohistochemistry for apoptosis/proliferation and regulatory proteins, RT-PCR for cytokine mRNA expression, and DNA sequencing for fecal gut microbiota. FOLFOX administration to colorectal cancer-bearing mice significantly inhibited tumor growth and the accompanying marked diarrhea and intestinal injury histologically characterized by the shortening of villi and destruction of intestinal crypts. Preventive administration of Lcr35 dose-dependently reduced the severity of diarrhea and intestinal mucositis without affecting the anti-tumor effect of FOLFOX. The numbers of apoptotic, NF-κB-, and BAX-activated cells increased after FOLFOX, and these responses were mitigated by Lcr35. TNF-α and IL-6 upregulation by FOLFOX treatment was attenuated by Lcr35. The fecal gut microbiota composition of Firmicutes and Bacteroidetes disturbed by FOLFOX was significantly reversed by Lcr35 toward a preferential profile. In conclusion, the oral probiotic Lcr35 prevented FOLFOX-induced intestinal mucositis in colorectal cancer-bearing mice. The putative mechanism might involve modulation of gut microbiota and proinflammatory responses with suppression of intrinsic apoptosis in intestinal injury.

RESUMO

Ulcerative colitis (UC) is a chronic inflammation of the large bowel characterized by diarrhea and a negative stool culture. However, several enteropathogens have been implicated as causative agents in UC. The differentiation between chronic infectious colitis (IC) and UC with concurrent infection is difficult owing to their similar clinical presentations. The study aimed to explore the presentations and diagnostic clues that enable differentiation between UC with concomitant infections and chronic IC. The study included 17 UC patients with a bacterial infection and 46 with chronic IC. The UC patients (47 ± 19 years) were younger than the chronic IC patients (58 ± 20 years) (P = 0.022). Bloody diarrhea was more common in UC than in chronic IC (58.8% vs 10.9%, P < 0.001). Previous antibiotic usage was a risk factor for chronic IC (5.9% vs 32.6%, P = 0.031). Malignancy was a common comorbidity of chronic IC (5.9% vs 34.8%, P = 0.022). UC patients had lower antibiotic response rates than chronic IC patients (60.0% vs 87.2%, P = 0.026). Aeromonas species and Clostridium difficile were common in both groups. Histological features of cryptitis and crypt abscess were useful in the diagnosis of UC (P = 0.052 and P = 0.016, respectively). Bloody diarrhea in a young adult, decreased response to antibiotic treatment, and results of endoscopy with biopsy are important features in the diagnosis of UC with bacterial infection.

RESUMO

Context: Both Helicobacter pylori and type 2 diabetes mellitus are possible risk factors for colon adenoma. Objective: The purpose of this study was to assess the interaction between H. pylori and hyperglycemia status on the risk of colon adenoma. Design, Setting, and Participants: This was a cross-sectional, retrospective study conducted at the MacKay Memorial Hospital, Taiwan. The study included 3943 subjects aged >40 years undergoing bidirectional gastrointestinal endoscopy on the same day between July 2006 and June 2015. All subjects had a gastric biopsy specimen tested for H. pylori. Main Outcome Measure: Colon adenoma with and without H. pylori infection at different hemoglobin A1c (HbA1c) levels. Results: The prevalence of colorectal adenomas in patients who were H. pylori-positive and H. pylori-negative was 37.3% and 27.29%, respectively. Multivariate logistic regression analysis identified male sex, age, body mass index, H. pylori infection, and HbA1c ≥6.5% as independent risk factors for adenoma; use of hypoglycemic agents decreased this risk. The prevalence of adenoma was increased with elevated HbA1c levels regardless of H. pylori status. The odds ratio (OR) for adenoma was 1.44 (95% confidence interval [CI], 1.20 to 1.73) if H. pylori was present or 1.68 (95% CI, 1.05 to 2.70) in patients who were H. pylori-negative but had HbA1c ≥7.0%. If both conditions were present, the OR was 4.79 (95% CI, 2.92 to 7.84). A 1% increase in HbA1c was associated with an increased prevalence of adenoma by 42.4% in H. pylori-positive subjects. Conclusions: The combination of H. pylori infection and elevated HbA1c is associated with an increased risk of colon adenoma.

RESUMO

Hepatic stem/progenitor cells (HPC) have been considered as a potential cell source of an alternative to liver transplantation. Production of large numbers of autologous HPC from small pieces of live tissue is crucial for the application of HPC-based liver therapy. In this study, we demonstrated that a synthetic 44-amino acid peptide (44-mer) derived from pigment epithelium-derived factor (PEDF) can facilitate the production of a large number of actively dividing HPC from normal adult rat livers in a 35-day culture period. The phenotypic properties of HPC were characterized by morphological observation, colony formation and high expression of classical HPC markers including epithelial cell adhesion molecule (EpCAM), leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) and tumor-associated calcium signal transducer (TROP2). The 44-mer stimulated HPC proliferation in vitro and in mouse livers injured by a single intraperitoneal injection of carbon tetrachloride. In addition, the 44-mer induced the phosphorylation of ERK1/2 and STAT3 in HPC. Blocking the activity of ERK or STAT3 with pharmacological inhibitors attenuated the effects of the 44-mer on the induction of HPC proliferation. The long-term expanded HPC still possessed a bipotent ability to differentiate towards bile duct cells and mature hepatocytes. These results imply that the PEDF peptide may be a simple and effective agent to improve HPC-based liver therapy.

RESUMO

BACKGROUND: The change of estimated glomerular filtration rate (eGFR) with off-treatment nucleos(t)ide analogues (NA) in chronic hepatitis B patients (CHB) is unclear. This study is aimed to evaluate the off-treatment eGFR after 3 years of therapy with telbivudine (LdT) or entecavir (ETV) and to assess predictive factors for eGFR improvement. METHODS: From January 2009 to December 2011, we identified NA-naïve patients who were at least 20 years of age diagnosed with compensated CHB. All patients received a 3-year NA treatment and 1 year off-treatment follow-up; the initial selection of patients for LdT or ETV treatment was at the physicians' discretion. An increase of more than 10% in eGFR from the baseline was identified as an improvement. The change of chronic kidney disease stages were recorded and compared with baseline at year 3 and year 4, respectively. RESULTS: This study included two groups consisting of 46 patients each (each with3 years of treatment with LdT or ETV). In LdT-treated patients, the mean eGFR increased from 94.3 ± 28.3 to 104.0 ± 31.2 mL/min/1.73 m2 in year 3 (p = 0.01) and from 104.0 ± 31.2 to 104.0 ± 28.8 mL/min/1.73 m2 in year 4 (p = 0.99). However, in ETV-treated patients, the mean eGFR decreased from 93.1 ± 26.1 to 85.5 ± 25.1 mL/min/1.73 m2 in year 3 (p = 0.0009) and from 85.5 ± 25.1 to 87.7 ± 24.8 mL/min/1.73 m2 in year 4 (p = 0.2). After a multivariate analysis, the predictors for the off-treatment eGFR improvement were the LdT treatment (odds ratio [OR], 3.97 (1.37-11.5), p = 0.01) and pre-treated eGFR (OR, 0.98 (0.95-1.00), p = 0.04). CONCLUSIONS: At year 4, 48.8 and 21.3% patients had an improved eGFR from baseline in LdT and ETV patients, respectively. Telbivudine may have a protective renal effect that can last for one year after treatment in non-cirrhotic CHB patients without a virological breakthrough.

RESUMO

BACKGROUND: Cardiovascular disease and colorectal cancer have severe consequences to human health and may occur simultaneously or sequentially. Carotid artery plaque is a predictor of cardiovascular disease, and colorectal adenoma is a premalignant lesion of colorectal cancer. We investigated the core risk factors of carotid artery plaque and colorectal adenoma. RESULTS: In total, 2361 subjects were enrolled. In multivariate analysis, age ≥ 60 years, male sex, BMI > 27, LDL > 130 mg/dL, HbA1c ≥ 6.5%, hs-CRP > 0.3 mg/L and H. pylori infection were independent risk factors for synchronous colorectal adenoma and carotid artery plaque formation. In the H. pylori-positive and -negative groups, the proportions and odds ratio (OR) for synchronous colon adenoma and carotid artery plaque increased with increasing HbA1c. OR for synchronous colon adenoma and carotid artery plaque was significantly higher in the participants with HbA1c levels of 5.7%-6.4% and HbA1c ≥ 6.5% than in those with normal HbA1c in the H. pylori-negative group. The OR was more significant increased for H. pylori-positive patients when HbA1c level ≥ 6.5% was 15.87 (95% CI 8.661-29.082, p < 0.0001). MATERIALS AND METHODS: The records of 4669 subjects aged > 40 years who underwent bidirectional gastrointestinal endoscopy and carotid artery ultrasound examination on the same day or within 12 months of endoscopy examination from January 2006 to December 2015 were reviewed. All subjects had a gastric biopsy specimen tested for Helicobacter pylori. CONCLUSIONS: Hyperglycemia combined with H. pylori infection was an increased risk factor for synchronous colorectal adenoma and carotid artery plaque formation. Diabetes control and H. pylori eradication may be warranted in higher prevalence areas.

RESUMO

Common bile duct (CBD) stones are common in elderly adults, but the effect of aging on the presentation of CBD stones remains to be evaluated. Recent studies have demonstrated that the clinical presentation of CBD stones may vary with age. Younger adults may present with classical biliary colic symptoms, whereas elderly adults may have no unapparent clinical features. Younger adults with CBD stones were significantly more likely to have abnormal liver function tests than those without. The sensitivity and accuracy of transabdominal ultrasound scans in screening for CBD stones increases with age. Antibiotic agents should be promptly administered to individuals with CBD stones complicated by cholangitis, but the effects of pharmacotherapy on renal function should be considered in elderly adults. Endoscopic retrograde cholangiopancreatography (ERCP) is considered to be first-line treatment for CBD stones, and endoscopic biliary sphincterotomy (EST) or endoscopic papillary balloon dilation (EPBD) along with ERCP is an adequate biliary drainage method in individuals with CBD stones. EPBD has a lower bleeding risk but higher post-ERCP risk of pancreatitis than EST. Longer-duration (>1 minute) EPBD may be preferred over EST because it is associated with a comparable risk of pancreatitis but a lower rate of overall complications, although recurrent cholangitis or unfavorable outcomes will increase during CBD dilation or in the presence of residual CBD stones.
