BACKGROUND: Biliary atresia is an extrahepatic progressive obliterate cholangiopathy that occurs in infants. Kasai procedure, a surgical method that can help re-establish bile flow from the liver into the intestine, is its first line treatment. Since infants with biliary atresia already have advanced hepatic dysfunction, all kinds of schemes should be considered to minimize further liver damage during surgery. The objective of this study was to compare the postoperative hepatic functions between the two commonly used inhalational anesthetics in infants undergoing the Kasai procedure (i.e., desflurane and sevoflurane). METHODS: This prospective, randomized, double-blind, single-center, and parallel group study included 40 children undergoing Kasai procedure. They were randomly allocated to Group S (sevoflurane) or Group D (desflurane). All the patients were anesthetized with designated anesthetic agent with the end-tidal concentration of about 0.8–1 minimum alveolar concentration. Postoperative hepatic functions were assessed by aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, prothrombin time, and total bilirubin. RESULTS: A total of 38 patients were selected for the study. In both groups, AST, ALT were increased in magnitude to the peak on postoperative day 0 and decreased to preoperative value at postoperative day 3. There were no significant differences between the groups in any laboratory results related to liver function. CONCLUSIONS: Sevoflurane and desflurane, inhalation anesthetics for maintaining anesthesia used in infants undergoing the Kasai procedure, did not show any difference in preserving postoperative hepatic function.

BACKGROUND: Pyridoxal-5'-phosphate (P5P), a coenzyme of the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) reactions, is required to measure aminotransferase levels (IFCC method). However, a modified IFCC method that uses a reagent devoid of P5P is commonly used in laboratories in Korea. To determine the differences between the two methods, we compared aminotransferase levels measured by using the IFCC method and modified IFCC method. METHODS: Serum levels of AST and ALT, with and without P5P, were measured in 2,318 patients. Based on the allowable limits of performance set by the Royal College of Pathologists of Australasia (RCPA), differences between the two methods were analyzed under various conditions. RESULTS: Higher AST and ALT values were obtained by the IFCC method compared to modified IFCC method, showing significant differences between the two methods (AST, 5.8±14.2 IU/L; ALT, 2.8±6.9 IU/L) (P<0.001). Values exceeding RCPA criteria were more frequently observed in emergency orders (AST, 65.8%; ALT, 14.4%) than in routine orders (AST, 3.2%; ALT, 9.6%), as well as in inpatient wards (AST, 70.4%; ALT, 18.5%) compared to outpatient clinics (AST, 56.6%; ALT, 10.0%). However, the differences between the two methods were not significant among the disease groups, except for the acute myocardial infarction group. CONCLUSIONS: The method using reagents without P5P underestimated aminotransferase activity. The effect of P5P was more significant in patients with acute myocardial infarction, considered as P5P-deficient. In conclusion, the IFCC method with P5P should be applied for measuring AST and ALT serum levels.

BACKGROUND/AIMS: We investigated the time of onset of antituberculous drug-induced hepatotoxicity (ADIH) and related characteristics. METHODS: Adult patients (n = 1,031) treated with first-line antituberculous drugs between February 2009 and January 2013 were enrolled. RESULTS: Of the 1,031 patients, 108 patients (10.5%) developed ADIH a mean of 39.6 +/- 43.7 days after treatment initiation. Twenty-eight patients (25.9%) developed ADIH within 7 days, 73 (67.6%) within 30 days, and the rest after 30 days. The < or = 30-day group was characterized by higher peak alanine aminotransferase (ALT) level and a high proportion of patients with maintenance of first-line antituberculous drugs compared to the > 30-day group. In subgroup analysis, the < or = 7-day group was characterized by higher baseline aspartate aminotransferase and ALT, high proportion of patients with maintenance of first-line antituberculous drugs, and high proportion of patients with extrapulmonary tuberculosis compared to patients with ADIH that developed beyond 7 days. In multivariate analysis, serum ALT > 40 IU/L (odds ratio [OR], 2.995; 95% confidence interval [CI], 1.580 to 5.680; p = 0.001) and presence of anti-hepatitis C virus (OR, 4.204; 95% CI, 1.822 to 9.700, p = 0.001) were independent risk factors for development of ADIH. CONCLUSIONS: Approximately 70% of the cases of ADIH occurred in the first month of antituberculous treatment, and were associated with continuation of the first-line drug regimen.

Based on their ability to differentiate into multiple cell types including hepatocytes, the transplantation of mesenchymal stem cells (MSCs) has been suggested as an effective therapy for chronic liver diseases. The aim of this study was to evaluate the safety, efficacy and therapeutic effects of MSCs in patients with chronic liver disease through a literature-based examination. We performed a systematic review (SR) and meta-analysis (MA) of the literature using the Ovid-MEDLINE, EMBASE and Cochrane Library databases (up to November 2014) to identify clinical studies in which patients with liver diseases were treated with MSC therapy. Of the 568 studies identified by the initial literature search, we analyzed 14 studies and 448 patients based on our selection criteria. None of the studies reported the occurrence of statistically significant adverse events, side effects or complications. The majority of the analyzed studies showed improvements in liver function, ascites and encephalopathy. In particular, an MA showed that MSC therapy improved the total bilirubin level, the serum albumin level and the Model for End-stage Liver Disease (MELD) score after MSC treatment. Based on these results, MSC transplantation is considered to be safe for the treatment of chronic liver disease. However, although MSCs are potential therapeutic agents that may improve liver function, in order to obtain meaningful insights into their clinical efficacy, further robust clinical studies must be conducted to evaluate the clinical outcomes, such as histological improvement, increased survival and reduced liver-related complications, in patients with chronic liver disease.

OBJECTIVETo investigate the efficacy of hematopoietic stem cell (HSC) transplantation via the hepatic artery vs. the portal vein for end-stage liver disease (ESLD).

METHODSPatients with hepatic decompensation were prospectively recruited from September 2010 to September 2012 to receive HSC transplantation via the hepatic artery or the portal vein. Liver function was examined at 3, 6, and 12 months after transplantation. Liver biopsy Results were analyzed using the Knodell score.

RESULTSEighty patients (58 males and 22 females) were enrolled in the study. The Child-Pugh score was grade B in 69 cases, and grade C in the remaining 11 cases. HSC transplantation was performed via the portal vein in 36 patients and via the hepatic artery in 44 patients. ALT levels decreased while serum albumin levels increased significantly in both groups at 6 and 12 months after HSC transplantation (P<0.05 compared with pre-transplantation levels). Total bilirubin levels decreased significantly in both groups at 3, 6, and 12 months after HSC transplantation (P<0.05 compared with pre-transplantation levels). Additionally, prothrombin time decreased in both groups at 12 months after HSC transplantation (P<0.05 compared with pre-transplantation level). There were no significant differences in ALT, total bilirubin and prothrombin time between the two groups either before or after transplantation. Moreover, Knodell score decreased significantly at 6 and 12 months. Histological examination showed that liver cell edema, degeneration, necrosis, and inflammation were significantly relieved at 3, 6, and 12 months after transplantation. The incidence of portal vein thrombosis, upper gastrointestinal bleeding, and hepatic encephalopathy were 1.25%, 3.75%, and 2.5% respectively. The one-year survival rate was 100%.

CONCLUSIONSAutologous HSC transplantation improves liver function and histology in ESLD patients. The administration route of HSC has no significant impact on the efficacy of transplantation.

OBJECTIVETo investigate the clinical application, indication, timing and prognosis of blood purification (artificial liver, BP) in treatment of acute liver failure in children.

METHODArtificial liver was used to treat 30 cases of pediatric acute liver failure (PALF), who were hospitalized in pediatric intensive care unit of Bayi Children's Hospital Affiliated to Beijing Military Command General Hospital, during March 2010 to July 2013. Simple plasma exchange (PE) mode was used for PALF without complications, while PE combined with continuous veno-venous hemodiafiltration (CVVHDF) mode was used for PALF with cerebral edema and/or hepatorenal syndrome and/or serious abnormality of electrolyte and acid-base balance.

RESULTSixteen cases survived and restored hepatic function, with a survival rate of 53.3%. Single PE therapy could significantly decrease total bilirubin (TBIL) from (293.96 ± 214.52) µmol/L to (155.64 ± 140.97) µmol/L (P = 0.033), increase prothrombin time activity (PTA) from (34.50 ± 18.34) % to (60.50 ± 33.97) % (P = 0.013), while it did not significantly influence ammonia from (156.43 ± 67.23) µmol/L to (124.03 ± 62.58) µmol/L (P = 0.156) and alanine transarninase (ALT) from (752.53 ± 1 291.84) U/L to (132.00 ± 98.57) U/L (P = 0.066). PE + CVVHDF therapy could significantly ameliorate TBIL from (326.90 ± 233.85) µmol/L to (157.53 ± 125.31) µmol/L (P = 0.033), ALT from (1 476.64 ± 1 728.18) U/L to (169.38 ± 207.18) U/L (P = 0.019), ammonia from (215.83 ± 83.92) µmol/L to (141.25 ± 63.09) µmol/L (P = 0.022) and PTA from (36.68 ± 23.13)% to (71.75 ± 50.50) % (P = 0.044). Prothrombin time (PT) from (29.71 ± 17.75)s to (16.27 ± 6.38)s (P = 0.008) , ALT from (1 574.11 ± 1 775.96) U/L to (145.81 ± 113.89 ) U/L (P = 0.003) , TBIL from (233.16 ± 219.70) µmol/L to (75.19 ± 86.07) µmol/L (P = 0.012) , ammonia from (182.75 ± 90.07) µmol/L to (101.81 ± 37.14) µmol/L (P = 0.002) and PTA from (38.38 ± 20.39)% to (83.13 ± 41.68)% (P = 0.001) in survived cases significantly ameliorated after BP therapy. TBIL from (394.04 ± 192.80) µmol/L to (249.34 ± 113.97) µmol/L (P = 0.023) in died cases declined significantly after BP therapy, while alteration of PT, ALT, ammonia , and PTA had no statistical significance (P > 0.10) after BP therapy.

CONCLUSIONPE + CVVHDF therapy could significantly ameliorate not only TBIL and PTA but also ammonia and ALT compared with single PE therapy. The decline of only an index like TBIL or ALT after BP therapy could not improve the prognosis. The inconsistency between serum bilirubin and ALT levels was an important factor that suggested poor prognosis of ALF, and it might increase survival rate to use BP therapy before that inconsistency emerged.

OBJECTIVETo evaluate the influence of liver function on pregnancy outcome of women who are infected with the hepatitis B virus (HBV) and who receive individualized nutrition management during the perinatal period.

METHODSA total of 210 pregnant women were enrolled for study between January 2011 and July 2013. The women were divided into the following groups according to self-selected participation in individualized nutritional treatment and management plans (n =87, observation group) or in routine prenatal care without any nutrition management plan (n =123, control group). Inter-group differences in pregnancy complications, liver function and perinatal outcome were assessed statistically.

RESULTSThe following pregnancy complications were recorded during the study:hypertension disorder, gestational diabetes, anemia and fetal growth restriction; however, the rates of these complications were significantly lower in the observation group than in the control group (P less than 0.05). The observation group also had significantly lower incidence rates of preterm labor, fetal distress and neonatal asphyxia (P less than 0.05). The observation group also had significantly lower proportions of hypoalbuminemia and abnormal liver function, and correlation analysis indicated that birth weight is correlated with the pregnant woman's energy and protein intake.

CONCLUSIONWomen with HBV can benefit from individualized nutrition management during the prenatal period, experiencing improved pregnancy outcome and reduced occurrence of pregnancy complications. The application of individualized and balanced nutrition management had no effect on fetal growth and development.

OBJECTIVE: To investigate and analyze the changes of postmortem human biochemical indexes. METHODS: Subclavian venous blood samples were collected from 81 cases of traffic fatalities. Thirteen blood biochemical indexes including liver function (ALT, AST, TBIL and DBIL), renal function (UA and Cr), cardiac function (CK, CK-MB and LDH), electrolytes (K+, Na+ and Cl-), and glucose (GLU) were tested by Roche cobas c311 automatic biochemical analyzer. The descriptive analysis was made by SPSS 17.0 statistical software. RESULTS: The values of ALT, AST, CK, CK-MB, LDH and K+ were higher than normal reference values with more fluctuations. The values of TBIL, DBIL, UA, Cr, Na+, Cl- and GLU were relatively stable with less fluctuations. CONCLUSION The postmortem human blood biochemical indexes of liver function, renal function, cardiac function, electrolytes and glucose could be affected by the factors, especially hemolysis and autolysis. The biochemical indexes, particularly enzymes, increased significantly with higher standard deviation.

OBJECTIVETo investigate the safety of treatment with ophthalmic artery cannulation for intra-arterial chemotherapy (IAC) for children with intraocular retinoblastoma (RB).

METHODIn the RB Treatment Center of General Hospital of Armed Police Forces between January 2009 and September 2011, 42 patients who were diagnosed intraocular RB and treated with ophthalmic artery cannulation for IAC, 8 patients were treated 1 circle, 31 patients were treated 2 circles and 3 patients were treated 3 circles (total, 96 times). Each month had IAC once. The ophthalmic and the whole body evaluations were performed during IAC and after IAC for each circle, the blood cell count, alanine aminotransferase (ALT), serum creatinine (Scr), CK-MB content before and after IAC for 1 circle, 2 circles and 3 circles were determined.

RESULT(1) In 52 eyes of 42 patients, 44 eyes (84.6%) were in remission. (2) Successful IAC was achieved in all cases, no severe side effects occurred during IAC. (3) The main ophthalmic complications were eyelid edema and blepharoptosis after IAC, the incidence for 1 circle was 18% (2/11) and 9% (1/11); for 2 circles was 29% (11/38) and 21% (8/38); for 3 circles was all 100% (3/3). The rare complications were vitreous hemorrhage and heterotropia, the incidence was all 2% (1/42). The incidence of eyelid edema and blepharoptosis had no significant differences for 1 circle IAC compared with 2 circles (P > 0.05); the incidence of eyelid edema and blepharoptosis had significant differences for 3 circles IAC compared with 2 circles and 1 circle (P < 0.01). (4) No fever, septicemia and other systemic toxic effects occurred. (5) ALT of 19% patients (8/42) elevated temporarily and CK-MB of 24% patients (10/42) increased. The blood cell counts, ALT, Scr, and CK-MB content before IAC had no significant differences compared with that at 24 h after IAC for 1 circle, 2 circles and 3 circles (P > 0.05).

CONCLUSIONOphthalmic artery cannulation for IAC is a safe and effective method in treating intraocular stage retinoblastoma.

A 58-year-old Chinese woman presented with deranged liver function tests, which was discovered incidentally during surveillance for statins therapy. Ultrasonography and computed tomography revealed a large lipoma originating from the greater omentum, which was treated with surgical resection. This case is reported due to the rare occurrence of omental lipomas.
