AIMTo summarize and compare the clinical characteristics of drug-induced liver injury (DILI) and primary biliary cirrhosis (PBC).METHODSA total of 124 patients with DILI and 116 patients with PBC treated at Shengjing Hospital Affiliated to China Medical University from 2005 to 2013 were included. Demographic data (sex and age), biochemical indexes (total protein, albumin, alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, indirect bilirubin, alkaline phosphatase, and gamma glutamyltransferase), immunological indexes [immunoglobulin (Ig) A, IgG, IgM, antinuclear antibody, anti-smooth muscle antibody, anti-mitochondrial antibody, and anti-mitochondrial antibodies] and pathological findings were compared in PBC patients, untyped DILI patients and patients with different types of DILI (hepatocellular type, cholestatic type and mixed type).RESULTSThere were significant differences in age and gender distribution between DILI patients and PBC patients. Biochemical indexes (except ALB), immunological indexes, positive rates of autoantibodies (except SMA), and number of cases of patients with different ANA titers (except the group at a titer of 1:10000) significantly differed between DILI patients and PBC patients. Biochemical indexes, immunological indexes, and positive rate of autoantibodies were not quite similar in different types of DILI. PBC was histologically characterized mainly by edematous degeneration of hepatocytes (n = 30), inflammatory cell infiltration around bile ducts (n = 29), and atypical hyperplasia of small bile ducts (n = 28). DILI manifested mainly as fatty degeneration of hepatocytes (n = 15) and spotty necrosis or loss of hepatocytes (n = 14).CONCLUSIONAlthough DILI and PBC share some similar laboratory tests (biochemical and immunological indexes) and pathological findings, they also show some distinct characteristics, which are helpful to the differential diagnosis of the two diseases. 相似文献

AIM: To compare the effect of percutaneous transhepatic portal vein embolization (PTPE) and unilateral portal vein ligation (PVL) on hepatic hemodynamics and right hepatic lobe (RHL) atrophy.METHODS: Between March 2005 and March 2009, 13 cases were selected for PTPE (n = 9) and PVL (n = 4) in the RHL. The PTPE group included hilar bile duct carcinoma (n = 2), intrahepatic cholangiocarcinoma (n = 2), hepatocellular carcinoma (n = 2) and liver metastasis (n = 3). The PVL group included hepatocellular carcinoma (n = 2) and liver metastasis (n = 2). In addition, observation of postoperative hepatic hemodynamics obtained from computed tomography and Doppler ultrasonography was compared between the two groups.RESULTS: Mean ages in the two groups were 58.9 ± 2.9 years (PVL group) vs 69.7 ± 3.2 years (PTPE group), which was a significant difference (P = 0.0002). Among the indicators of liver function, including serum albumin, serum bilirubin, aspartate aminotransferase, alanine aminotransferase, platelets and indocyanine green retention rate at 15 min, no significant differences were observed between the two groups. Preoperative RHL volumes in the PTPE and PVL groups were estimated to be 804.9 ± 181.1 mL and 813.3 ± 129.7 mL, respectively, with volume rates of 68.9% ± 2.8% and 69.2% ± 4.2%, respectively. There were no significant differences in RHL volumes (P = 0.83) and RHL volume rates (P = 0.94), respectively. At 1 mo after PTPE or PVL, postoperative RHL volumes in the PTPE and PVL groups were estimated to be 638.4 ± 153.6 mL and 749.8 ± 121.9 mL, respectively, with no significant difference (P = 0.14). Postoperative RHL volume rates in the PTPE and PVL groups were estimated to be 54.6% ± 4.2% and 63.7% ± 3.9%, respectively, which was a significant difference (P = 0.0056). At 1 mo after the operation, the liver volume atrophy rate was 14.3% ± 2.3% in the PTPE group and 5.4% ± 1.6% in the PVL group, which was a significant difference (P = 0.0061).CONCLUSION: PTPE is a more effective procedure than PVL because PTPE is able to occlude completely the portal branch throughout the right peripheral vein. 相似文献

BACKGROUND: Biochemical marker combinations, including alpha2-macroglobulin, haptoglobin, apolipoprotein A1, gamma-glutamyl transpeptidase, and total bilirubin (all part of FibroTest) plus alanine aminotransferase (all part of ActiTest), are being developed as alternatives to liver biopsy in patients with chronic hepatitis C and other various chronic liver diseases. Considering this premise, the primary aim of this study was to assess the impact of meal intake on FibroTest and ActiTest results. Such studies are very important for patients, as many clinical errors have been related to the absence of baseline evidence. RESULTS: Intra-individual variation was assessed for the 6 above components and for FibroTest and ActiTest, by measuring time dependent variations before and one hour after a standard meal in 64 subjects. These consisted of 29 healthy volunteers and 35 patients with chronic liver diseases. Meal intake had no significant impact on any of the six components, or on FibroTest or ActiTest, as assessed by repeated measure variance analyses (ANOVA all p > 0.90); the Spearman correlation coefficient ranged from 0.87 (total bilirubin) to 0.995 (gamma-glutamyl transpeptidase). The coefficients of variation (CV) between fasting and postprandial measurements fluctuated for the six components from 0.09 (apolipoprotein A1) to 0.14 (alpha2-macroglobulin), and from 0.09 for FibroTest to 0.13 for ActiTest. In contrast, meal intake had a significant impact on triglycerides (ANOVA p = 0.01, CV = 0.65) and glucose (ANOVA p = 0.04, CV = 0.31). As for the prediction of liver injury, the concordance between fasting and postprandial predicted histological stages and grades was almost perfect, both for FibroTest (kappa = 0.91, p < 0.001) and ActiTest (kappa = 0.80, p < 0.001). CONCLUSIONS: The intra-individual variation of biochemical markers was low, and it was shown that measurements of FibroTest, ActiTest and their components are not significantly modified by meal intake. This fact makes the screening of patients at risk of chronic liver diseases more convenient. 相似文献

The hydrogen breath test after a lactulose oral load in the fasting period is currently used to measure mouth to cecum transit time (MCTT). However, the reproducibility of this test is poor, and normal values are very scattered. The aim of the study was to determine the reproducibility of hydrogen breath test for MCTT measurement and hydrogen production after administration of 2 disaccharides: lactulose and lactitol ingested in the fasting state and postprandial period. Twelve healthy volunteers (6 men and 6 women; mean age = 34.6 +/- 9.6 years) were studied eight times in a random order, each disaccharide being studied twice in the fasting state and twice in the postprandial period. In the later, lactulose or lactitol was ingested 30 min after a liquid meal completely absorbed (400 kcal; glucide: 55 p. 100, lipid: 30 p. 100, protein: 15 p. 100; 400 ml of Inkopeptide). The MCTT was significantly increased with both disaccharides in the postprandial period as compared with the fasting state (P less than 0.0001). There was nos significant correlation between the 2 measurements of the MCTT in the fasting state, in contrast, the 2 measurements of the MCTT were closely related in the fed state (r = 0.62, P less than 0.05, et r = 0.79, P less than 0.003 for lactulose and lactitol respectively). During both periods no significant difference was found in the MCTT between lactulose and lactitol. As well, hydrogen production did not differ between the 2 disaccharides, but was significantly increased in the postprandial period, and in non methane producers.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

AIM: To investigate the relationship between plasma acylated ghrelin levels and the pathophysiology of functional dyspepsia.METHODS: Twenty-two female patients with functional dyspepsia and twelve healthy volunteers were recruited for the study. The functional dyspepsia patients were each diagnosed based on the Rome III criteria. Eligible patients completed a questionnaire concerning the severity of 10 symptoms. Plasma acylated ghrelin levels before and after a meal were determined in the study participants using a commercial human acylated enzyme immunoassay kit; electrogastrograms were performed for 50 min before and after a standardized 10-min meal containing 265 kcal.RESULTS: There were no significant differences in plasma acylated ghrelin levels between healthy volunteers and patients with functional dyspepsia. However, in patients with functional dyspepsia, there was a negative correlation between fasting plasma acylated ghrelin levels and the sum score of epigastric pain (r = -0.427, P = 0.047) and a positive correlation between the postprandial/fasting plasma acylated ghrelin ratio and the sum score of early satiety (r = 0.428, P =0.047). Additionally, there was a negative correlation between fasting acylated ghrelin plasma levels and fasting normogastria (%) (r = -0.522, P = 0.013). Interestingly, two functional dyspepsia patients showed paradoxically elevated plasma acylated ghrelin levels after the meal.CONCLUSION: Abnormal plasma acylated ghrelin levels before or after a meal may be related to several of the dyspeptic symptoms seen in patients with functional dyspepsia. 相似文献

AIM:To investigate the outcome of living donor liver transplantation(LDLT)recipients transplanted with small-for-size grafts(SFSGs).METHODS:Between November 2001 and December2010,196 patients underwent LDLT with right lobe liver grafts at our center.Recipients were divided into 2 treatment groups:group A with an actuarial graft-to-recipient weight ratio(aGRWR)<0.8%(n=45)and group B with an aGRWR≥0.8%(n=151).We evaluated serum liver function markers within 4 wk after transplantation.We also retrospectively evaluated the outcomes of these patients for potential effects related to the recipients,the donors and the transplantation procedures based upon a review of their medical records.RESULTS:Small-for-size syndrome(SFSS)developed in 7 of 45 patients(15.56%)in group A and 9 of 151patients(5.96%)in group B(P=0.080).The levels of alanine aminotransferase and aspartate aminotransferase in group A were higher than those in group B during early period after transplantation,albeit not significantly.The cumulative 1-,3-and 5-year liver graft survival rates were 82.22%,71.11%and 71.11%for group A and 81.46%,76.82%,and 75.50%for group B patients,respectively(P=0.623).However,univariate analysis of risk factors associated with graft survival in group A demonstrated that the occurrence of SFSS after LDLT was the only significant risk factor affecting graft survival(P<0.001).Furthermore,multivariate analysis of our data did not identify any additional significant risk factors accounting for poor graft survival.CONCLUSION:Our study suggests that LDLT recipients with an aGRWR<0.8%may have liver graft outcomes comparable to those who received larger size grafts.Further studies are required to ascertain the safety of using SFSGs. 相似文献

Aim: The primary aim of this study was to investigate the effects of different audio stimulations on gastric myoelectrical activity and sympathovagal balance in adolescents compared with adults. Methods: The study was performed in 11 adults and 12 adolescents. Each subject underwent two sessions, one for classical music, and the other for noise. Each session consisted of 30 min of baseline, 30 min of fasting audio stimulation, a test meal, 30 min of fed audio stimulation, and 30 min of recovery. Electrocardiogram and electrogastrogram were both recorded throughout each session. Results: (i) In the fasting state, both classical music and noise impaired gastric slow wave activity in adolescents. In adults, noise had no effects while classical music moderately improved slow wave rhythmicity. (ii) In the fed state, neither noise nor music had any effects on gastric slow waves. (iii) In the fasting state, both noise and music increased the sympathovagal balance in adolescents; in adults only noise had such an effect. (iv) The test meal increased the sympathovagal balance in all groups. Conclusions: Gastric slow waves and the sympathovagal balance are more strongly affected by audio stimulation in adolescents than in adults. The test meal normalizes the audio stimulation‐induced differences between the groups. 相似文献

AIM: To observe the effect of response-guided add-on therapy with adefovir(ADV) and lamivudine(LAM) in cirrhotic hepatitis B(CHB) patients.METHODS: A total of 100 patients with CHB and cirrhosis were divided into three arms according to hepatitis B virus(HBV) DNA level after 24 wk LAM monotherapy: Arm A(complete response, HBV DNA ≤ 60 IU/m L, n = 49), Arm B(partial response, HBV DNA: 60-2000 IU/m L, n = 31) and Arm C(inadequate response, HBV DNA 2000 IU/m L, n = 20). ADV was added to LAM at week 48 in Arms A and B, but at week 24 in Arm C. Virological response, YMDD mutations, biochemical response, and liver function were evaluated.RESULTS: Comparison of the three arms demonstrated that early complete virologic response at week 24was associated with maintained viral suppression(undetectable rate of HBV DNA at week 144 was 95.96%, 66.67% and 35.29%, respectively, P = 0.000) and reduced YMDD mutations(mutation rate at week 144 was 0%, 3.23% and 15%, respectively, P = 0.015) after 144 wk treatment. For patients who failed to achieve complete virological response at week 24, switching to combination therapy further decreased HBV DNA level by 1 log10 IU/m L. All three arms obtained biochemical benefits including decline of alanine aminotransferase and elevation of albumin. In patients who developed HBV DNA breakthrough for YMDD mutations, ADV add-on therapy did not induce further multiple drug resistance to LAM or ADV.CONCLUSION: Optimized response-guided add-on therapy of ADV and LAM maintains long-term suppression of HBV DNA and improves liver function in CHB patients with compensated liver cirrhosis. 相似文献

The aim of the present study was to determine whether glycogen confers protection on hepatocytes during hypothermic ischemic liver preservation. Sixteen male Wistar rats (250–300 g) were divided into two groups. FAST animals (n = 8) were fasted (low hepatic glycogen levels) and FEED animals (n = 8) were fed (high hepatic glycogen levels). The livers were removed and preserved in Euro-Collins solution at 2–4°C after increasing times of ischemia, i.e. time 0 (immediately after perfusion), 3 h, 6 h and 24 h. Liver samples were collected at each time for biochemical determination of hepatic glycogen and for study of ADP-activated state III mitochondrial function. The FAST group showed a lower glycogen level than the FEED group. There was a significant fall in glycogen levels in each group which started at 6 h of preservation in FAST group and 24 h of preservation in FEED group (P < 0.05). The mitochondrial oxygen consumption during state III mitochondrial respiration did not differ between groups or times. These data show that the capacity of oxidation-phosphorylation of the liver was maintained intact regardless of glycogen levels. 相似文献

The aim of the study was to investigate the incidence, the clinical course and outcome of liver involvement and autoimmune hepatic diseases in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Liver function tests (LFT) (i.e. aspartate and alanine aminotransferase [AST, ALT], gamma-glutamyl transpeptidase [gamma-GT], alkaline phosphatase [ALP] and total bilirubin) were analysed at disease onset in therapy-naïve patients and during remission in patients with granulomatosis with polyangiitis (GPA, n?=?67), microscopic polyangiitis (MPA, n?=?28) and eosinophilic granulomatosis with polyangiitis (EGPA, n?=?14). Results were correlated to the Birmingham Vasculitis Activity Score version 3 (BVAS v.3). Also, serologic tests for other autoimmune hepatic diseases were performed in these patients. During the active state, LFT abnormalities could be detected in 54 AAV patients (49.4 %). ALT, gamma-GT and ALP were significantly higher in GPA patients compared to MPA or EGPA patients at disease onset (p?<?0.05). Increased values for gamma-GT in GPA patients correlated with the BVAS (p?<?0.01) and were associated with pulmonary involvement, pulmonary-renal syndrome and a longer time to remission. Increased LFT in GPA patients decreased subsequently towards normal levels after initiation of therapy (p?<?0.01). No case of severe liver involvement or autoimmune hepatic liver diseases was found in AAV patients. Liver involvement was mainly restricted to GPA patients, is associated with the disease activity and indicates a poorer outcome in patients with GPA. Progressive liver involvement or autoimmune hepatic diseases were not observed. 相似文献

AIM: Obesity is positively associated with hyperinsulinaemia, and it has been suggested that hyperinsulinaemia may contribute to maintain the obese state in insulin-resistant obese individuals. The aim of the present study was to investigate the effect of inhibition of insulin secretion by diazoxide on weight loss in obese, normoglycaemic (fasting plasma glucose of > or =6.1 mmol/l), hyperinsulinaemic (fasting plasma insulin of > or =100 pmol/l) adults during a 2.5 MJ/day energy-deficient diet. METHODS: In an 8-week, double-blind, placebo-controlled parallel design, 35 overweight and obese subjects (age: 23-54 years, body mass index: 27-66 kg/m(2)) were randomized either to 2 mg/kg/day (maximum 200 mg/day) of oral diazoxide or to placebo. Body composition and resting energy expenditure (REE) were measured before and after the intervention. Blood samples, and appetite sensations by visual analogue scales, were collected during fasting, during an oral glucose tolerance test (OGTT) and 4 h postprandially after a test meal. Subsequently, an ad libitum meal was given. RESULTS: Thirty-one subjects completed the protocol. Eight weeks of diazoxide decreased incremental area under the response curve (iAUC) for insulin (iAUC(insulin)) and for C-peptide (iAUC(C-peptide)) and increased iAUC for glucose (iAUC(glucose)) during the OGTT and the test meal compared with the use of placebo (p < 0.003). No differences in changes between the groups in body weight, body fat, REE or appetite were observed during the 8-week trial. CONCLUSION: These findings do not suggest that hyperinsulinaemia per se contributes to maintenance of the obese state, and insulin secretion inhibition seems not a promising drug target. 相似文献

Electrogastrography (EGG) permits measurements of the gastric electrical activity. However, normal values of electrical activity are poorly defined. In addition, limited data are available on the effect of age and gender. Therefore, in 40 healthy subjects (age range: 19–90 years) normal values for several EGG parameters were assessed after an overnight fast for 1 hr in the fasting and fed state after ingestion of a standardized solid-liquid meal. The electrical signals were capture by a pair of surface electrodes sonographically placed on the skin overlying the gastric antrum. The dominant electrical frequency was predominantly in the defined normal frequency range between 2 and 4 cycles per minute (cpm) (P<0.001) and was higher in the postprandial than in the preprandial period (3.1 cpm vs 2.8 cpm,P=0.02). The instability of the electrical rhythm calculated by a dominant frequency instability coefficient (DFIC) was postprandially lower than in the fasting state (P=0.04). The electrical power (amplitude) increased postprandially (postprandial to fasting power ratio =2.4). To evaluate the influence of age and gender on normal values the subjects were divided into four groups (median age: male, 28 and 69 years; female, 25 and 67 years). The most parameters did not differ significantly between the groups. However, DFIC was different between the groups (P<0.05), with elderly women revealing lowest DFIC. In conclusion, normal values for several EGG parameters evaluated in this study should be included in the analysis of gastric electrical activity. The magnitude of electrical frequency and power are not influenced by age and gender, whereas the instability of the electrical frequency is influenced by these factors. 相似文献

Background
During surgery, ischaemic pre- (IPC) and post-conditioning (IPO) protects the liver against ischaemia/reperfusion injuries (I/R-injuries). The impact of ischaemic conditioning on liver regeneration has been less well studied. Angiogenesis is an important part of liver regeneration after hepatectomy. The aim of the present study was to investigate the effect of ischaemia/reperfusion and ischaemic conditioning on the expression of genes with angiogenic potential in a model of rat liver ischaemia.Methods
A model of total liver ischaemia (30 min) and reperfusion (30 min) was employed using Wistar rats. Rats were randomized into five groups: (C) control (IRI) ischaemic, IPC, IPO and IPC + IPO. Liver enzymes were sampled at the end of reperfusion. Liver biopsies were analysed using cDNA microarrays.Results
Alanine aminotransferase (ALT) increased significantly in all the ischaemic groups compared with controls (P = 0.000). Searching databases 99 genes involved in rat liver angiogenesis were identified. Compared with group (C) the number of genes significantly up-regulated was as follows: IRI (n = 5), IPC (n = 24), IPO (n = 33) and IPC + IPO (n = 18). No genes were down-regulated in the four groups compared with controls.Conclusion
Ischaemic conditioning, as demonstrated in the present study, seems to be potent activators of angiogenic genes. This might be favourable to the regenerating liver. 相似文献15.

AIM: To test whether colchicine would be an effective antifibrotic agent for treatment of chronic liver diseases in patients who could not be treated with α-interferon.METHODS: Seventy-four patients (46 males, 28 females) aged 40-66 years (mean 53 ± 13 years) participated in the study. The patients were affected by chronic liver diseases with cirrhosis which was proven histologically (n = 58); by chronic active hepatitis C (n = 4), chronic active hepatitis B (n = 2), and chronic persistent hepatitis C (n = 6). In the four patients lacking histology, cirrhosis was diagnosed from anamnesis, serum laboratory tests, esophageal varices and ascites. Patients were assigned to colchicine (1 mg/d) or standard treatment as control in a randomized, double-blind trial, and followed for 4.4 years with clinical and laboratory evaluation.RESULTS: Survival at the end of the study was 94.6% in the colchicine group and 78.4% in the control group (P = 0.001). Serum N-terminal peptide of type III procollagen levels fell from 34.0 to 18.3 ng/mL (P = 0.0001), and pseudocholinesterase levels rose from 4.900 to 5.610 mU/mL (P = 0.0001) in the colchicine group, while no significant change was seen in controls. Best results were obtained in patients with chronic hepatitis C and in alcoholic cirrhotics.CONCLUSION: Colchicine is an effective and safe antifibrotic drug for long-term treatment of chronic liver disease in which fibrosis progresses towards cirrhosis. 相似文献

AIM: To analyze the associations of pancreatic fat with other fat depots and β-cell function in pediatric nonalcoholic fatty liver disease (NAFLD).METHODS: We examined 158 overweight/obese children and adolescents, 80 with NAFLD [hepatic fat fraction (HFF) ≥ 5%] and 78 without fatty liver. Visceral adipose tissue (VAT), pancreatic fat fraction (PFF) and HFF were determined by magnetic resonance imaging. Estimates of insulin sensitivity were calculated using the homeostasis model assessment of insulin resistance (HOMA-IR), defined by fasting insulin and fasting glucose and whole-body insulin sensitivity index (WBISI), based on mean values of insulin and glucose obtained from oral glucose tolerance test and the corresponding fasting values. Patients were considered to have prediabetes if they had either: (1) impaired fasting glucose, defined as a fasting glucose level ≥ 100 mg/dL to < 126 mg/dL; (2) impaired glucose tolerance, defined as a 2 h glucose concentration between ≥ 140 mg/dL and < 200 mg/dL; or (3) hemoglobin A1c value of ≥ 5.7% to < 6.5%.RESULTS: PFF was significantly higher in NAFLD patients compared with subjects without liver involvement. PFF was significantly associated with HFF and VAT, as well as fasting insulin, C peptide, HOMA-IR, and WBISI. The association between PFF and HFF was no longer significant after adjusting for age, gender, Tanner stage, body mass index (BMI)-SD score, and VAT. In multiple regression analysis with WBISI or HOMA-IR as the dependent variables, against the covariates age, gender, Tanner stage, BMI-SD score, VAT, PFF, and HFF, the only variable significantly associated with WBISI (standardized coefficient B, -0.398; P = 0.001) as well as HOMA-IR (0.353; P = 0.003) was HFF. Children with prediabetes had higher PFF and HFF than those without. PFF and HFF were significantly associated with prediabetes after adjustment for clinical variables. When all fat depots where included in the same model, only HFF remained significantly associated with prediabetes (OR = 3.38; 95%CI: 1.10-10.4; P = 0.034).CONCLUSION: In overweight/obese children with NAFLD, pancreatic fat is increased compared with those without liver involvement. However, only liver fat is independently related to prediabetes. 相似文献

AIM: To elucidate the prevalence and risk factors for gallstones, primarily focusing on Helicobacter pylori(H. pylori) infection. METHODS: A total of 10016 Chinese subjects, who had undergone physical examination, fasting 13 C urea breath test and abdominal ultrasonography, had sufficient blood test data, and had finished a questionnaire, were included in this cross-sectional study. Participants(n = 1122) who had previous eradication of H. pylori were studied separately. RESULTS: Gallstones were discovered in 9.10% of men and 8.58% of women, with no significant sex difference. Multivariate analyses displayed that age, aspartate aminotransferase, total cholesterol, H. pylori infection, hepatitis C virus(HCV) infection, and fattyliver had a significant association with gallstones(P 0.05). Successive multiple logistic regression analysis including index of odds ratio(OR) and standardized coefficient(β) indicated that older age(OR/β = 1.056/0.055), H. pylori infection(OR/β = 1.454/0.109), HCV infection(OR/β = 1.871/0.123), and fatty liver(OR/β = 1.947/0.189) had a significant positive association with gallstones. After age stratification, H. pylori infection and fatty liver still had a significant positive association with gallstones in any age-specific groups, whereas HCV infection had a significant positive association in patients aged 40 years. The prevalence of gallstones among H. pylori-positive, H. pylori-eradicated, and H. pylori-negative subjects was 9.47%, 9.02%, and 8.46%, respectively. The matched analysis showed that gallstones among H. pylori eradicated subjects was significantly lower compared with H. pylori-positive subjects(P 0.05).CONCLUSION: H. pylori infection and fatty liver have a significant positive association with gallstones. H. pylori eradication may lead to prevention of gallstones. 相似文献

Impaired gastric slow wave rhythmicity in patients after bone marrow or stem cell transplant 总被引:2,自引:0,他引:2
Patients after bone marrow or stem cell transplant often develop gastrointestinal symptoms. The aim of this study was to investigate possible impairment of gastric myoelectrical activity in these patients. The study was performed in 15 patients who had had bone marrow or stem cell transplant and 13 healthy subjects. Gastric myoelectrical activity was assessed using electrogastrography. The electrogastrogram (EGG) was made for 30 min in the fasting state and 60 min after a test meal (475 kcal; turkey sandwich). Overall and minute-by-minute spectral analyses were performed to derive various parameters of the EGG. Compared with the healthy controls, the patients showed a significantly higher percentage of arrhythmia (no obvious rhythmicity observed in the EGG) in both fasting (17.6 ± 3.8% vs 7.1 ± 2.17%, P < 0.02) and fed (11.4 ± 2.65% vs 4.19 ± 1.04%, P < 0.02) state. The patients showed a significantly higher instability coefficient of the dominant frequency in the fasting state than in the controls (0.51 ± 0.06 vs 0.29 ± 0.18, P < 0.008). The total average symptom score was 3.93 ± 0.84 in the patients and 0 in the controls, and a relatively weak but significant correlation was found between the symptom scores and the percentage of arrhythmia in the patients in fed state (r = 0.69, P < 0.02). It was concluded that patients with bone marrow or stem cell transplant have excessive arrhythmia that is correlated with their dyspeptic symptoms. 相似文献

Aim: To clarify the impact of visceral fat on chronic liver diseases such as non‐alcoholic fatty liver disease (NAFLD) and hepatitis C, we investigated the effects of lifestyle modifications on the amount of visceral fat, liver biochemistry and serum ferritin levels in patients with liver disease. Methods: Eighty‐two patients (NAFLD, n = 37; hepatitis C, n = 45) were advised to adopt lifestyle modifications, including dietary changes and exercise, and these were maintained for 6 months. Bodyweight, percentage of body fat, visceral fat area (VFA) and serum alanine aminotransferase (ALT) and ferritin were measured before and after intervention. Results: In NAFLD, the mean VFA of 134.5 cm2 was significantly reduced to 125.3 cm2 after 6 months (P < 0.001). ALT levels improved significantly between the values measured before and after intervention (P = 0.039). The VFA prior to intervention was 100 cm2 in hepatitis C patients and it was reduced significantly after 6 months to 95.6 cm2 (P < 0.001). ALT levels also improved significantly in the hepatitis C patients (P < 0.001). The serum ferritin levels also reduced in these patients. Improvements in serum ALT and ferritin levels correlated with the amount of visceral fat reduction in both groups (P = 0.046, P = 0.008, respectively). Conclusion: These findings demonstrate that restriction of calorie and iron intake results in reduction of visceral fat, liver enzymes and ferritin in patients with chronic liver disease. Visceral fat may be a central target for future interventions, not only in NAFLD but also in hepatitis C. 相似文献
