Post-hepatectomy liver failure(PHLF) is a leading cause of morbidity and mortality following major liver resection. The development of PHLF is dependent on the volume of the remaining liver tissue and hepatocyte function. Without effective pre-operative assessment, patients with undiagnosed liver disease could be at increased risk of PHLF. We report a case of a 60-year-old male patient with PHLF secondary to undiagnosed alpha-1-antitrypsin deficiency(AATD) following major liver resection. He initially presented with acute large bowel obstruction secondary to a colorectal adenocarcinoma, which had metastasized to the liver. There was no significant past medical history apart from mild chronic obstructive pulmonary disease. After colonic surgery and liver directed neo-adjuvant chemotherapy, he underwent a laparoscopic partially extended right hepatectomy and radio-frequency ablation. Post-operatively he developed PHLF. The cause of PHLF remained unknown, prompting reanalysis of the histology, which showed evidence of AATD. He subsequently developed progressive liver dysfunction, portal hypertension, and eventually an extensive parastomal bleed, which led to his death; this was ultimately due to a combination of AATD and chemotherapy. This case highlights that formal testing for AATD in all patients with a known history of chronic obstructive pulmonary disease, heavy smoking, or strong family history could help prevent the development of PHLF in patients undergoing major liver resection. 展开更多

AIM:To evaluate the association between alpha-1 antitrypsin deficiency(A1ATD) and hepatocellular carcinoma(HCC) in patients with end-stage liver disease(ESLD).METHODS:Patients with cirrhosis and ESLD referred to the Cleveland Clinic Foundation for liver transplantation between 2003 and 2014 were included in the study(N = 675). ESLD was defined as having histological features of cirrhosis and/or radiological evidence of cirrhosis in the context of portal hypertension(ascites,variceal bleeding,thrombocytopenia,or hepatic encephalopathy). A1 ATD was diagnosed using phenotype characterization(MZ or ZZ),liver biopsy detection of PAS-positive diastaseresistant(PAS+) globules,or both. Patients with other causes of liver diseases such as hepatitis C virus(HCV),alcoholic liver disease and non-alcoholic steatohepatitis(NASH) or NASH were also included in the study. HCC was diagnosed by using imaging modalities,biopsy findings,or explanted liver inspection. Follow-up time was defined as the number of years from the diagnosis of cirrhosis to the diagnosis of hepatocellular carcinoma,or from the diagnosis of cirrhosis to the last follow up visit. The rate of HCC was assessed using time-tointerval analysis for interval censored data.RESULTS:This study included 675 patients. 7% of subjects had A1ATD(n = 47). Out of all subjects who did not have A1 ATD,46% had HCV,17% had alcoholic liver disease,19% had NASH and 18% had another primary diagnosis. Of the 47 subjects with A1 ATD,15 had a primary diagnosis of A1ATD(PI*ZZ phenotype and PAS+ globules),8 had a PI*MZ phenotype alone,14 had PAS+ alone,and 10 had both the PI*MZ phenotype and PAS+. Median follow-up time was 3.4(25th,75 th percentiles:1,5.2) years. The overall rate of hepatocellular carcinoma in all subjects was 29%(n = 199). In the A1 ATD group,the incidence rate of HCC was 8.5% compared to 31% in the group of patients with other causes of cirrhosis(P = 0.001). Patients with ESLD due to A1 ATD had the lowest yearly cumulative rate of hepatocellular carcinoma at 0.88% per year compared to 2.7% for those with HCV cirrhosis,1.5% in patients with NASH and 0.9% in alcohol-induced liver disease(P < 0.001).CONCLUSION:Within this group of patients with ESLD,there was no significant association between A1 ATD and increased risk of HCC. 展开更多

One hundred and fifty-three consecutive cases of HCC and 25 controls from autopsy material were studied by immunohistochemical method in this paper. A review of the histopathology and demonstration of AFP, alpha- 1-antichymotrypsin (AACT), alpha 1-antitrypsin (AAT) and CEA were made.Among the tumor markers. AACT yielded the highest positive rate, 109 cases (71%) out of 153 HCC. CEA was the next, 95 cases (62%) .AFP and AAT gave the same result, 72 cases (47%) . AACT, AAT and CEA were not found in the controls. AFP was present in a few hepatocytes in 1 of 25 controls. The results were in keeping with serum tests so far as the highest positive rate being AACT was concerned. Therefore, combined determination of AACT and AFP would seem a better screening method than by that of AFP alone for survey of HCC. 展开更多

The study was aimed at the evaluation of the effects of breed, age, different digestion stimulators, and dietary crude protein (CP) level on the activities of proteolytic enzymes in pancreatic tissue and duodenal chymus (in vivo), serum trypsin and α1-proteinase inhibitor (A1PI) concentrations in meat-type chicks. The study of age dynamics of trypsin and A1PI concentrations was performed on the chicks of hybrid cross “Smena-8”and two parental lines (Plymouth Rock and Cornish) fed standard commercial corn-wheat-SBM diets. Twenty birds per breed were euthanized at 1, 7, 14, 21, 28 and 35 days of age to obtain blood samples and pancreatic homogenate. Experiments on the effects of different digestion promotors (probiotic, acidifier, phytobiotic, enzymatic preparation) and different CP levels (finisher diet, CP 20%, vs. ground corn, CP 8.5%) were performed on 12 hybrid chicks with fistulated duodenum from 14 to 50 days of age. The following conclusions were made: 1) At 1 day of age high proteolytic activity in pancreatic tissue and maximal serum concentrations of trypsin and A1PI were found in both hybrid and parental lines. Since 7 to 35 days of age A1PI concentration was nearly constant, serum trypsin concentration decreased while proteolytic activity in pancreatic tissue exhibited undulate increase;2) Proteolytic activity in pancreatic tissue was higher in hybrids compared to the parental lines from 7 to 35 days of age (p 0.05);3) Supplementation of diet with exogenous enzymes stimulated the digestion due to the increase in protease activity in duodenal chymus by 9.1% compared to unsupplemented control (p 0.05);4) Proteolytic activity in duodenal chymus significantly responded to the substitution of ground corn for the complete diet by 2-fold decrease while serum trypsin concentration responded by 2.5-fold increase (p 0.001). This fact can indicate that physiological functions of digestive proteases are not confined to the digestive processes. 展开更多

GFAP is a specific antigen of glial element, but Alpha-1-antichymotrypsin has not been reported in the literature. Alpha-1-antichymotrypsin was guided by GFAP using PAP method to the astrocytes of 137 gliomas. 120 (87%) gliomas were positive for Alpha-1-antichymotrypsin. Of these 120 gliomas, 86 (72%) gave diffuse distribution, 17 (14%) gave focal distribution, and 17 (14%) gave scattered distributions. Alpha-1-antichymotrypsin in glioma tissue may be an important tumor marker for diagnosis. 展开更多

METHODS Multiple databases were searched using combinations of pertinent terms. Articles were selected describing panniculitis treatment in patients with AAT < 11 μmol and/or PiZZ genotype, with no language limitation. All relevant articles were accessed in full text. Independent review of abstracts and full manuscripts was conducted by 2 reviewers, and quality assessment by one reviewer(checked by a second). Data extraction was conducted byone reviewer(checked by a second). Narrative synthesis only was conducted, as data were unsuitable for metaanalysis.RESULTS Thirty-two case reports and 4 case series were found. Augmentation therapy(infusions of plasma-derived AAT) was the most successful, with complete resolution of symptoms in all patients. Dapsone is a less expensive option, and it achieved clinical resolution in 62% of patients, but it is very poorly tolerated. Among other single-agent antibiotics, doxycycline was the most successful with complete clinical resolution seen in 33% of patients. Immunosuppressants were largely unsuccessful; 80% of patients exhibited no response. Liver transplantation and therapeutic plasma exchange displayed complete resolution in 66% of patients. Other strategies, such as non-steroidal anti-inflammatory drugs or antibiotics other than dapsone did not show sufficient response rates to recommend their use. Authors note the risk of bias imposed by the type of evidence(case reports, case series) available in this field.CONCLUSION Dapsone is the recommended first line therapy for AATD panniculitis, followed by augmentation therapy. Plasma exchange may be an alternative in the setting of rapidly progressive disease. 展开更多

Green tea (Camellia sinensis)-associated hepatotoxicity is reported. However, the presence of alpha-1 antitrypsin MZ phenotype as a predisposing factor to green tea-associated drug-induced liver injury (DILI) is unknown. A previously healthy woman with alpha-1 antitrypsin MZ phenotype who took SlimQuick?, an herbal supplement containing green tea extract, developed severe hepatotoxicity requiring corticosteroid treatment. Green tea-associated hepatotoxicity is reviewed and alpha-1 antitrypsin MZ phenotype as a predisposing factor to green tea-associated DILI is discussed. Liver biopsy demonstrated marked inflammation with necrosis suggestive of toxic injury with diffuse alpha-1 antitrypsin globule deposition on immunostaining. Corticosteroid therapy resulted in rapid clinical improvement. Alpha-1 antitrypsin MZ phenotype may increase vulnerability to herbal hepatotoxicity. 展开更多
