Background Low alanine aminotransaminase (LALT) levels may be seen in patients with inflammatory bowel disease (IBD),but there has been no study about the frequency and its clinical significance.We aimed to analyze the frequency of LALT,and its clinical significance in children with IBD.Methods The study included the 89 patients with IBD without hepatobiliary involvement.LALT was defined as ALT levels < 5 U/L.Demographic and clinical findings and outcome of the patients with and without LALT were compared.Results LALT was found 47.1% of the patients.At initial examination,it was more common in female patients (92.3 vs.41.3%,P < 0.001) and patients with CD (57.7 vs.30.2%,P=0.01).75% of the patients with penetrating Crohn's disease (CD) had LALT (P=0.002).Hemoglobin (10.4±2.1 vs.11.7± 1.9 g/dL,P=0.01),folic acid (5.2±3.3 vs.8.6±5.9 ng/mL,P =0.02) and serum albumin levels (3.6 ± 0.8 vs.4.7 ± 5 g/dL,P =0.002) were significantly low in patients with LALT.LALT was associted with the disease relapse within 2 weeks in 12 of the 16 patients with LALT whereas it was seen in 16 of the 73 patients without LALT during the follow-up (75 vs.21.9%,P < 0.001).Additionally,steroid dependency was more common in patients with LALT during the follow-up (62.5 vs.12.3%,P<0.001).Conclusions LALT is common in children with IBD especially in CD and associated with low hemoglobin,albumin and folic acid levels.It may be a marker of relapse and steroid dependency.

Animal Nutrition 2015年第4期1卷 373-377页

作者： Jun Jiang Lin Feng Ling Tang Yang Liu Weidan Jiang Xiaoqiu Zhou College of Animal Science and Technology Sichuan Agricultural University Animal Nutrition Institute Sichuan Agricultural University Fish Nutrition and Safety Production University Key Laboratory of Sichuan Province Sichuan Agricultural University Animal Nutrition Institute Sichuan Academy of Animal Science

The present study investigated the effect of body weight on body composition, digestive and absorptive capacity, transaminase activities in hepatopancreas and muscle, and plasma ammonia concentration of Jian carp(Cyprinus carpio var.Jian). A total of 750 Jian carps(18.0 ± 0.2 g) were randomly distributed into five groups with three replicates and fed the same diet for 56 days. Tissue and plasma samples were collected on days 14, 28,42, and 56. The results were used to develop a mathematical model for specific growth rate, body moisture and fat content, aspartate transaminase activity and alanine aminotransferase activity in hepatopancreas and muscle, plasma ammonia concentration, and trypsin, chymotrypsin, lipase, and amylase activities in hepatopancreas and intestine, activities of creatine kinase, Na^+/K^+-ATPase, alkaline phosphatase, and γ-glutamyl transpeptidase in intestine in Jian carp. There were linear relationships between natural logarithms of above indexes and body weight. The body moisture and fat content, digestive and absorptive enzymes activities, and transaminase activities showed negative allometry against body weight of Jian carp which were partial reasons to explain fish growth rate decreasing.

Journal of Huazhong University of Science and Technology(Medical Sciences) 2006年第3期26卷 384-385页

作者：胡丽华杨菊红崔天盆邢辉蔡鹏程 Department of Laboratory Union Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan 430022 China

In order to explore the value of combined detection of atypical lymphocytes （ATL） and transaminase （alanine aminotransferase, ALT＇ asparate aminotransferase, AST） in the diagnosis of infectious mononucleosis （IM）, The data of blood routine and liver function were collected from 54 IM patients, 34 acute hepatitis （AH） patients, 44 upper respiratory infection （URI） patients in Union Hospital during March 2002 to March 2005. Same data were also collected from 40 healthy children as normal control. These data were analyzed retrospectively. Both proportion of atypical lymphocytes and enzyme activity of transaminase were elevated simultaneously （ALT〉40 IU/L, AST〉45 IU/L） in 57.4% （31/54） IM patients. There was significant difference （P〈0.01） between IM group and the other groups. Combined detection of atypical lymphocytes and transaminase can be regarded as a diagnostic marker of infectious mononucleosis.

AIM: To assess the diagnostic accuracy,of aminotransferase-to-platelet ratio index(APRI) alone and with antischistosomal antibody(Ab) in patients with hepatitis C virus(HCV) and schistosomiasis coinfection. METHODS: This retrospective study included medical records of three hundred and eighty three Egyptianmen patients who had undergone percutaneous liver biopsy between January 2006 to April 2014 in tertiary care hospital in Qatar for diagnosis or monitoring purpose were selected. Data of patients > 18 years of age were included in the study. The values of HCV RNA titer and antischistosomal antibody titer were also taken into consideration. Patients were excluded from the study if they had any other concomitant chronic liver disease,including; history of previous antiviral or interferon therapy,immunosuppressive,therapy,chronic hepatitis B infection,human immunodeficiency virus co-infection,autoimmune hepatitis,decompensated liver disease,hepatocellular carcinoma,prior liver transplantation,and if no data about the liver biopsy present. RESULTS: Median age of patients was 46 years. About 7.1% had no fibrosis,whereas 30.4%,37.5%,20.4%,and 4.6% had fibrosis of stage Ⅰ,Ⅱ,Ⅲ,and Ⅳ respectively. In bivariate analysis,APRI score,levels of AST,platelet count and age of patient showed statistically significant association with liver fibrosis(P < 0.0001); whereas antischistosomal antibody titer(P = 0.52) and HCV RNA titer(P = 0.79) failed to show a significant association. The respective AUC values for no fibrosis,significant fibrosis,severe fibrosis and cirrhosis of APRI score were 63%,73.2%,81.1% and 88.9% respectively. This showed good sensitivity and specificity of APRI alone for grading of liver fibrosis. But the inclusion of anti-Schistosoma antibody did not improve the prediction of fibrosis stage. CONCLUSION: The study results suggest that noninvasive biochemical markers like APRI are sensitive and specific in diagnosing the degree of fibrosis and cirrhosis in patients with coinfection of HCV and schistosomiasis as

Coronavirus disease 2019(COVID-19),caused by the novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is an acute infectious disease that spreads mainly through the respiratory route.Besides interstitial pneumonia,a number of other clinical manifestations were noticed in COVID-19 patients.In particular,liver and spleen dysfunctions have been described both as complications of COVID-19 and as potential predisposing factors for severe COVID-19.Liver damage is rather common in COVID-19 patients,and it is most likely multifactorial,caused by the direct insult of SARS-CoV-2 to the liver by the cytokine storm triggered by the virus,by the use of hepatotoxic drugs,and as a consequence of hypoxia.Although generally mild,liver impairment has been found to be associated with a higher rate of intensive care unit admission.A higher mortality rate was reported among chronic liver disease patients.Instead,spleen impairment in patients with COVID-19 has been poorly described.The main anatomical changes are the architectural derangement of the B cell compartment,white pulp atrophy,and reduction or absence of lymphoid follicles,while,from a functional point of view,the IgM memory B cell pool is markedly depleted.The outcome of COVID-19 in asplenic or hyposplenic patients is yet to be defined.In this review,we will summarise the current knowledge regarding the impact of SARS-CoV-2 on the liver and spleen function,as well as the outcome of patients with a pre-existent liver disease or defective spleen function.

引用

Asian Pacific Journal of Tropical Biomedicine 2011年第3期1卷 193-199页

作者： Mahuya Sengupta Gauri Dutta Sharma Biswajit Chakraborty Department of Biotechnology Assam University Department of Life Science Assam University

Objective:To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl_4 intoxicated Swiss albino mice.Methods:first group of mice(n=5) received CCl_4 treatment at a dose of 0.5 mL/kg bw(i.p.) for 7 days.Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for IS days.The third group was given both the turmeric extract(for 15 days,orally) and CCl_4(for last 7 days,i.p.).The fourth group was kept as a control.To study the liver function,the transaminase enzymes(SGOT and SGPT) and bilirubin level were measured in the serum of respective groups.For assaying the immunotherapeutic action of Curcuma longa(C.longa),non specific host response parameters like morphological alteration,phagocytosis,nitric oxide release,myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups.Results:The result of present study suggested that CCl_4 administration increased the level of SCOT and SGPT and bilirubin level in serum.However,the aqueous extract of turmeric reduced the level of SGOT, SCFT and bilirubin in CCl_4 intoxicated mice.Apart from damaging the liver system,CCl_4 also reduced non specific host response parameters like morphological alteration,phagocytosis, nitric oxide release,myeloperoxidase release and intracellular killing capacity of peritoneal macrophages.Administration of aqueous extract of C.longa offered significant protection from these damaging actions of CCl_4 on the non specific host response in the peritoneal macrophages of CCl_4 intoxicated mice.Conclusions:In conclusion,the present study suggests that C.longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.

AIM: To investigate the efficacy and safety of combined de novo lamivudine (LAM) and adefovir dipivoxil (ADV) therapy in hepatitis B virus (HBV)-related decompensated liver cirrhosis patients. METHODS: One hundred and forty patients with HBVrelated decompensated cirrhosis were recruited, 70 patients were treated with combined LAM and ADV de novo therapy, and the other 70 patients were treated with LAM alone as controls. The follow-up period was 144 wk. All patients with LAM resistance were shifted to ADV. RESULTS: The percentage of HBV-related decompensated cirrhosis patients with undetectable HBV DNA inde novo combination group was 51.6% (33/64), 84.2% (48/57), and 92.3% (49/53) by weeks 48, 96, and 144, respectively. In monotherapy group, HBV DNA negativity rate was 46.1% (30/65), 56.1% (32/57), and 39.2% (20/51) by weeks 48, 96 and 144, respectively. There was a significant difference between the two groups by weeks 96 and 144 (P = 0.012 and 0.001). The hepatitis B e antigen seroconversion rate was 28.1% (9/32), 40.0% (12/30), and 53.6% (15/28) in the combination group by weeks 48, 96 and 144, respectively, and 24.2% (8/33), 31.0% (9/29), and 37.0% (10/27) by weeks 48, 96 and 144, respectively, in monotherapy group. A total of 68.6% (44/64), 84.2% (48/57), and 92.5% (49/53) patients achieved alanine aminotransferase (ALT) normalization by weeks 48, 96 and 144, respectively in the combination group. In monotherpy group, the ALT normalization rate was 64.6% (42/65) by week 48, 73.7% (42/57) by week 96, and 80.4% (41/51) by week 144. No patients in the combination group exhibited detectable resistance for at least 144 wk. The cumulative resistance rate in monotherapy group at weeks 48, 96, and 144 was 20.0%, 36.8%, and 56.9%. Both combination group and monotherapy group demonstrated an improvement in Child-Turcotte Pugh and Model for End-Stage Liver Disease scores at weeks 48, 96, and 144. All patients tolerated both combination and monotherapy. The ceratinine levels and glomerular filtration rate remained normal

Persistent hypertransaminasemia in asymptomatic children: A stepwise approach

引用

World Journal of Gastroenterology 2013年第18期19卷 2740-2751页

作者： Pietro Vajro Sergio Maddaluno Claudio Veropalumbo Department of Medicine and Surgery Pediatrics University of Salerno 84081 Baronissi Italy European Laboratory for Food Induced Disease 84081 Baronissi Italy Department of Translational Medical Sciences Pediatrics Medical School of the University of Naples "Federico Ⅱ" 80131 Naples Italy

We aimed to examine the major causes of isolated chronic hypertransaminasemia in asymptomatic children and develop a comprehensive diagnostic flow diagram. A MEDLINE search inclusive of publications throughout August 2012 was performed. We found only a small number of publications that had comprehensively investigated this topic. Consequently, it was difficult to construct a diagnostic flowchart similar to those already available for adults. In children, a "retesting panel" prescription, including gamma-glutamyl transpeptidase and creatine kinase in addition to aminotransferases, is considered a reasonable approach for proficiently confirming the persistence of the abnormality, ruling out cholestatic hepatopathies and myopathies, and guiding the subsequent diagnostic steps. If re-evaluation of physical and historical findings suggests specific etiologies, then these should be evaluated in the initial enzyme retesting panel. A simple multistep diagnostic algorithm incorporating a large number of possible pediatric scenarios, in addition to the few common to adults, is available. Accurately classifying a child with asymptomatic persistent hypertransaminas-emia may be a difficult task, but the results are critical for preventing the progression of an underlying, possibly occult, condition later in childhood or during transition. Given the high benefit/cost ratio of preventing hepatic deterioration, no effort should be spared in diagnosing and properly treating each case of persistent hypertransaminasemia in pediatric patients.
