The therapeutic potential of bone marrow-derived mesenchymal stem cells on hepatic cirrhosis

Hepatic cirrhosis is the end-stage of chronic liver diseases. The majority of patients with hepatic cirrhosis die from life-threatening complications occurring at their earlier ages. Liver transplantation has been the most effective treatment for these patients. Since liver transplantation is critically limited by the shortage of available donor livers, searching for an effective alternative therapy has attracted great interest in preclinical studies. The transplantation of autologous bone marrow-derived mesenchymal stem cells holds great potential for treating hepatic cirrhosis. Mesenchymal stem cells can differentiate to hepatocytes, stimulate the regeneration of endogenous parenchymal cells, and enhance fibrous matrix degradation. Experimental and clinical studies have shown promising beneficial effects. This review is intended to translate the bench study results to the patients' bedside. The potential interventions of mesenchymal stem cells on cirrhosis are illustrated in terms of the cellular and molecular mechanisms of hepatic fibrogenesis.     

Immunopathogenesis of primary biliary cirrhosis: an old wives' tale

Primary biliary cirrhosis (PBC) is a cholestatic liver disease characterised by the autoimmune destruction of the small intrahepatic bile ducts. The disease has an unpredictable clinical course, but may progress to fibrosis and cirrhosis. Although medical treatment with urseodeoxycholic acid is largely successful, some patients may progress to liver failure requiring liver transplantation. PBC is characterised by the presence of disease specific anti-mitochondrial (AMA) antibodies, which are pathognomonic for PBC development. The disease demonstrates an overwhelming female preponderance and virtually all women with PBC present in middle age. The reasons for this are unknown; however several environmental and immunological factors may be involved. As the immune systems ages, it become less self tolerant, and mounts a weaker response to pathogens, possibly leading to cross reactivity or molecular mimicry. Some individuals display immunological changes which encourage the development of autoimmune disease. Risk factors implicated in PBC include recurrent urinary tract infection in females, as well as an increased prevalence of reproductive complications. These risk factors may work in concert with and possibly even accelerate, immune system ageing, contributing to PBC development. This review will examine the changes that occur in the immune system with ageing, paying particular attention to those changes which contribute to the development of autoimmune disease with increasing age. The review also discusses risk factors which may account for the increased female predominance of PBC, such as recurrent UTI and oestrogens.

In-hospital cerebrovascular complications following orthotopic liver transplantation: A retrospective study

Background

Cerebrovascular complications are severe events following orthotopic liver transplantation (OLT). This study aimed to observe the clinical and neuroimaging features and possible risk factors of in-hospital cerebrovascular complications in the patients who underwent OLT.

Patients and methods

We retrospectively reviewed 337 consecutive patients who underwent 358 OLTs. Cerebrovascular complications were determined by clinical and neuroimaging manifestations, and the possible risk factors were analyzed in the patients with intracranial hemorrhage.

Results

Ten of 337 (3.0%) patients developed in-hospital cerebrovascular complications (8 cases experienced intracranial hemorrhage and 2 cases had cerebral infarction), and 6 of them died. The clinical presentations were similar to common stroke, but with rapid deterioration at early stage. The hematomas on brain CT scan were massive, irregular, multifocal and diffuse, and most of them were located at brain lobes and might enlarge or rebleed. Infarcts presented lacunar and multifocal lesions in basal gangliar but with possible hemorrhagic transformation. The patients with intracranial hemorrhage had older age and a more frequency of systemic infection than non-intracranial hemorrhage patients. (P = 0.011 and 0.029, respectively).

Conclusion

Posttransplant cerebrovascular complications have severe impact on outcome of the patients who received OLT. Older age and systemic infection may be the possible risk factors of in-hospital intracranial hemorrhage following OLT.     

The course of liver cirrhosis not preceded by viral hepatitis with p articular reference to toxic etiology]

The study was aimed at analysing the epidemiological structure of patients with liver cirrhosis without HBsAg treated in 1980-1988. There were 231 of such cases in this period of time. The most frequent cause of liver cirrhosis in patients under 60 years of life was chronic alcoholism whereas 40% of the diagnosed liver cirrhosis in older persons was of unclear etiology. Patients complaints, clinical examinations, and results of the laboratory tests were analysed. The course of the disease was more severe in alcohol-produced liver cirrhosis leading to the haemorrhage from esophageal varices in 36%, and coma in 8% of cases. Alcohol-produced liver cirrhosis promoted other complications such as: cancer of the liver, hepato-renal syndrome or encephalopathy. Liver cirrhosis of unclear etiology in the elderly may be a consequence of the prolonged exposition to environmental pollutants. More severe course of alcohol-produced liver cirrhosis may depend on simultaneous action of two harmful factors: alcohol and environmental pollutants.     

Frequency of poor quality of life and predictors of health related quality of life in cirrhosis at a tertiary care hospital Pakistan

ABSTRACT: BACKGROUND: Cirrhosis produces variety of symptoms which eventually lead to a negative impact on Health Related Quality of Life (HRQOL). The general aim of this study was to evaluate the magnitude of poor HRQOL and to assess factors related with HRQOL in patients with CLD in Pakistan. FINDINGS: This was a cross sectional study conducted in gastroenterology outpatient clinics of Aga Khan University Hospital, Karachi on adult patients with cirrhosis. In this study chronic liver disease questionnaire (CLDQ) was used to assess HRQOL of these patients and CLDQ score was used as an outcome measure to determine factors related with HRQOL. 273 participants were recruited in the study; 155 (57%) were males. Mean age of participants was 49 [PLUS-MINUS SIGN] 11 years. The most common cause for cirrhosis was viral infection 247(91.5%). Mean Model for End Stage Liver Disease (MELD) score was 12.6 [PLUS-MINUS SIGN] 6.8 and 2/3 of patients 209 (76.6%) had advanced cirrhosis in Child Turcot Pugh (CTP) B or C stage. Poor HRQOL was seen in 187(69%; 95% C.I.: 63%, 74%) of the participants. Mean CLDQ score was 4.36 [PLUS-MINUS SIGN]1.1. Amongst all of the domains, fatigue domain had lower CLDQ score. Hemoglobin (beta = 0.09 [SE = 0.04]), Albumin (beta = 0.32[SE = 0.09]), Diastolic Blood Pressure (DBP) (beta = 0.01[0.005) prior history of decompensation (beta = 0.98[SE = 0.39] were significant factors associated with HRQOL in patients with liver cirrhosis. CONCLUSION: Frequency of poor health related quality of life determined by CLDQ score is high in patients with liver cirrhosis. Hemoglobin, serum albumen, prior history of decompensation (like encephalopathy and upper gastro intestinal bleed), are associated with health related quality of life.     

Liver transplantation in patients with alcoholic cirrhosis: selection criteria and rates of survival and relapse.

OBJECTIVE--To evaluate the outcome of liver transplantation in patients with alcoholic cirrhosis with respect to selection criteria, survival, and evidence suggesting a return to harmful drinking. DESIGN--Nine year retrospective study. SETTING--Cambridge and King''s College Hospital liver transplant programme. SUBJECTS--24 Patients (three women, 21 men) with alcoholic cirrhosis. MAIN OUTCOME MEASURES--Survival, rehabilitation, and clinical and laboratory evidence of a return to harmful drinking after transplantation. RESULTS--15 Patients were selected for transplantation because of repeated admission to hospital for the complications of advanced portal hypertension despite abstinence, and six because they had a hepatocellular carcinoma superimposed on alcoholic cirrhosis. Three patients who were not abstinent received transplants. The one year survival rate was 66%, and of the 18 patients surviving at least three months, 17 had been rehabilitated. In three patients laboratory variables and histological examination of the liver suggested a return to drinking, though they did not admit to taking alcohol. These patients represented the only cases in the series that were not abstinent before transplantation. CONCLUSIONS--The survival and rehabilitation of patients who received transplants for alcoholic cirrhosis compared favourably with those of patients who received transplants for cirrhosis of other aetiology. The criteria for selection for liver transplantation in patients with alcoholic cirrhosis should include recurrent complications related to severe portal hypertension despite maximum medical treatment in addition to a minimum period of six months of abstinence before transplantation.
