Impact of Obesity on a Chinese Population with Erosive Esophagitis and Barrett's Esophagus

BACKGROUND/AIMS: The aim of this study was to investigate the associations between obesity and erosive esophagitis (EE) or Barrett's esophagus (BE) in a Chinese population. METHODS: Data from subjects were retrospectively collected from 2006 to 2009. Individuals with BE were identified and age- and sex-matched at a 1:2 ratio with normal esophagocardial junction and EE patients. The subjects were stratified into two groups: the normal weight group and overweight/obesity group (body mass index ≥25 mg/m²) or the normal waist group and abdominal obesity group (waist circumference ≥90 cm for men and ≥80 cm for women). RESULTS: Overall, 45%, 72%, and 52% were overweight/obese and 23%, 65%, and 18% had abdominal obesity in the normal, EE, and BE groups, respectively. Positive associations were identified between EE and overweight/obesity (odds ratio [OR], 3.14; 95% confidence interval [CI], 1.75 to 5.66) and abdominal obesity (OR, 6.22; 95% CI, 3.34 to 11.57); however, the associations were nonsignificant between BE and overweight/obesity (OR, 1.32; 95% CI, 0.67 to 2.61) or abdominal obesity (OR, 0.73; 95% CI, 0.31 to 1.73). Female BE patients had a significantly increased rate of being overweight/obese. CONCLUSIONS: Obesity is a contributing factor in EE. The association of BE and obesity was not significant, with the exception of female BE cases.

Sequential Treatment with Lamivudine and Peg-interferon Therapy in Patients with E-positive Chronic Hepatitis B and High Viral Load.

Background: Patients with chronic hepatitis B virus (HBV) who are positive for e antigen (HBeAg) and have a high viral load are considered to be poor therapeutic responders to pegylated interferon (PEG-IFN). The aim of this study was to assess the therapeutic response of sequential therapy, lamivudine (LAM) followed by PEG-IFN, in these cases. Methods: Chronic HBV patients who were HBeAg positive, with HBV DNA over 107 IU/ml and ALT 2-10 times the upper normal limit, and who were treatment naive were included in our study. Those with concurrent hepatitis C or HIV infection, liver cirrhosis or decompensated cirrhosis, or pregnancy were excluded. The enrolled cases received therapy with PEG-IFN monotherapy for 48 weeks (PEG-IFN group) or sequential therapy with lamivudine (LAM) for 4 weeks followed by PEG-IFN therapy for 48 weeks (LAM/ PEG-IFN group). Results: There were 10 patients in each group, and there were no differences in age, gender, HBV genotype, pre-treatment ALT, and HBV DNA levels between the two groups. The biochemical, virological and serologic responses within 24 weeks after treatment were 40%-60%, 30-50%, and 40-50%, respectively, in the PEG-IFN group, compared with 70%, 20-40%, and 20-40%, respectively, in the LAM/PEG-IFN group. The rates of positive EOT were 30% and 10% in the PEG-IFN group and the LAM/PEG-IFN group, respectively, with rates of 40% and 10% in the SVR-12-week subgroup, and 30% and 20%, respectively, in the SVR-24-week subgroup. The therapeutic responses between the two groups showed no differences. Conclusion: In chronic HBV patients who were positive for HBeAg positive and with a high viral load at baseline, similar therapeutic responses were noted between the sequential LAM/PEG-IFN therapy group and the PEG-IFN monotherapy group. Further research with a higher number of patients and a prolonged LAM course are needed to confirm the efficacy of this approach.

Impact of overlapping functional gastrointestinal disorders on the presentation and quality of life of patients with erosive esophagitis and nonerosive reflux disease

The aim of this study was to investigate the impact of overlapping functional gastrointestinal disorder [FGID] on the quality of life of patients with nonerosive reflux disease [NERD] and erosive esophagitis [EE]. Data from patients with NERD and EE were collected between January 2009 and March 2010. These cases were further stratified into the subgroups of overlapping NERD-functional dyspepsia [FD] NERD-irritable bowel syndrome [IBS], EE-FD, EE-IBS, and NERD or EE alone according to the symptoms. All patients completed the modified Chinese GERDQ and the SF-36 questionnaires. Of the 222 enrolled patients, 96 [43.2%] had NERD and 126 [56.8%] had EE. Overlap of FGID occurred in 43.8-45.8% of the NERD patients, and in 41.3-44.4% of EE cases. The impact of overlapping FGID on patient quality of life was greater in the patients with overlapping NERD-FD compared to those with NERD alone [mean SF-36 total scores 59 vs. 72, adjusted p = 0.025] and the cases with overlapping EE-FD compared to those with EE alone [mean SF-36 total scores 53.19 vs. 73.11, adjusted p = 0.047]. There were no significant differences between the individuals with overlapping NERD/EE-IBS and those with NERD/EE alone. There was a high prevalence of overlapping FGID, with both FD and IBS, among the GERD patients. The individuals with overlapping GERD and FD had lower quality of life scores than those with GERD alone

The Risk Factors and Quality of Life in Patients with Overlapping Functional Dyspepsia or Peptic Ulcer Disease with Gastroesophageal Reflux Disease

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD), functional dyspepsia (FD), and peptic ulcer disease (PUD) impact the daily lives of affected individuals. The aim of this study was to compare the risk factors and impacts on life quality of overlapping FD or PUD in patients with GERD. METHODS: Data from patients diagnosed with GERD were collected between January and November 2009. FD was defined using the Rome III diagnostic criteria. The overlapping GERD-FD or GERD-PUD groups were classified as concomitant GERD and FD or peptic ulcers. The characteristics of these individuals were analyzed. RESULTS: There were 63, 48, and 60 patients in the GERD only, overlapping GERD-FD, and overlapping GERD-PUD groups, respectively. Significantly younger age, female gender, lower body weight and body mass index, and higher rates of tea consumption were noted in the GERD-FD group. Patients in the GERD-FD group exhibited the lowest quality of life scores, both with respect to physical and mental health, on the Short Form 36 domains. CONCLUSIONS: Patients with concomitant GERD and FD were more likely to be younger and female. Overlapping GERD and FD had the worst impact on the quality of life of the affected individuals.

Characteristics of symptom presentation and risk factors in patients with erosive esophagitis and nonerosive reflux disease

The aim of this study was to investigate the effect of gender on symptom presentation and quality of life of patients with erosive esophagitis [EE] and nonerosive reflux disorder [NERD]. Medical records from patients with gastroesophageal reflux disease [GERD] between January and December 2009 were reviewed. The patients were assigned to either the EE or the NERD group. The general demographic data, the modified Chinese GERDQ scores and the Short Form [SF]-36 life quality questionnaire scores of the two groups of patients were compared. Of the 261 patients, 87 [33.3%], 86 [33.0%] and 88 [33.7%] patients were classified into the EE, the NERD and the control groups, respectively. The patients in the EE group were significantly older [48.94 +/- 17.38 vs. 43.34 +/- 12.67 years], were predominately male [58.6 vs. 39.5%], had more frequently hiatal hernia [34.5 vs 17.4%], had a higher body weight [67.57 +/- 15.13 vs. 61.06 +/- 11.08 kg] and a higher body mass index [24.09 +/- 4.61 vs. 22.68 +/- 3.12] than those in the NERD group. The GERD-specific symptom scores and the general life quality scores of the EE and the NERD groups were similar, and both groups had lower life quality scores than the control group did. The female patients with NERD had a higher frequency of GERD symptoms and lower quality of life scores. Gender had no effect on symptom scores or life quality scores in the EE group. The GERD-specific symptom severity and general quality of life scores of the EE and the NERD patients were similar. Gender had a great influence on symptom presentation and quality of life in patients with NERD, but not in those with EE

The suitable range of PT-INR for Chinese people with acute deep venous thrombosis treated by warfarin anticoagulation therapy / 中国综合临床

Objective To explore the suitable range of PT-INR for Chinese people with acute deep venous thrombosis (DVT) treated by warfarin anticoagulation therapy. Methods Eighty seven DVT patients with indications to warfarin anticoagulation therapy were enrolled into the study and divide into two groups randomly. Patients from group A (n=47) took warfarin to adjust the PT-INR to range 1.7-2. 5,and patients from group B (n =40) took warfarin to adjust the PT-INR to range 2. 0-3. 0. The therapeutic effectiveness and the incidence of bleeding complications were compared between two groups. Results Forty-six patients (46/47,98%) had limb swelling symptoms relief in group A with one exception,which was diagnosed as pelvic tumor by ultrasonography,CT and tumor markers examination later. No patient underwent bleeding in group A Thirty eight patients (38/40,93%) had limb swelling symptoms relief in group group B with two exceptions,of which one case had Cockett syndrome and the other one had unknown aetiology. The total effective rate of group B was 95% . As to the complications of this group,3 patients had slight gum and nasal mucous membrane bleeding, 1 patient developed gastrointestinal bleeding. No patients had pulmonary embolism in both groups. Conclusion For Chinese people,anticoagulation therapy of acute deep venous thrombosis to adjust the range of PT-INR to 1.7-2. 5, shows good effectiveness and significantly reduced bleeding complications.

Clinical application of xenogenic (porcine) acellular dermal atrix (ADM) in scar treatment / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the role of xenogenic (porcine) ADM as dermal substitute in scar treatment.</p><p><b>METHODS</b>After scar excision, the wounds were covered with composite grafts of DR procine ADM and autologous thin split-thickness grafts in one stage or in two stages.</p><p><b>RESULTS</b>22 out of 47 cases were treated in two-staged procedure. After the ADMs were applied to the wound, the autologous thin split-thickness grafts were implanted 7 days later. 25 cases were treated in one-staged procedure. The survival rates of composite grafts were (88.3 +/- 3.7)% for subcutaneous recipient bed and (89.7 +/- 3.4)% for deep fascia recipient bed in group with two-staged procedure, compared with (92.5 +/- 4.1)% and (93.2 +/- 5.2)%, respectively, in group with one-staged procedure. Early after grafts taken, the grafts had a pink colour and smooth surface. The patients were followed up for 90 days at most. The survived composite grafts were durable, elastic, smooth and soft with good function and appearance like normal skin. They could even be pinched up. The scar along the edge of the grafts was slightly hypertrophic.</p><p><b>CONCLUSIONS</b>The survival rate of composite graft is higher in patients with one-staged procedure. The elasticity and textural of the taken grafts are better on subcutaneous recipient bed than on deep fascia recipient bed, though the function has no difference. Xenogenic (porcine) ADM can be an optimal dermal substitute for wound coverage after scar excision.</p>
