Glomerular tip adhesions predict the progression of IgA nephropathy

Background

Focal segmental glomerulosclerosis-like lesions have been proposed to be predictive factors for IgA nephropathy. This single center, retrospective cohort study was designed to clarify which clinical and pathological factors are predictive of decreased estimated glomerular filtration rate (eGFR) at 5 and 10 years in IgA nephropathy patients.

Methods

Of the 229 patients with IgA nephropathy who were admitted to Aichi Medical University Hospital between 1986 and 2010, 57 were included in this study during the 5 to 10 years after renal biopsy. Clinical, laboratory, and pathological parameters were analyzed by multiple linear regression analysis with backward elimination to determine independent risk factors. After identifying such factors, we compared patients with and without each factor using the Student’s t test, Wilcoxon test, or Mann–Whitney U test.

Results

Four variables were identified as predictive factors for progression of IgA nephropathy: initial eGFR (p?=?0.0002), glomerular tip adhesion (p?=?0.004), global sclerosis (p?=?0.019), and diastolic blood pressure (p?=?0.024). The annual decrease in eGFR of patients with (n?=?9) or without glomerular tip adhesions (n?=?48) was 4.13?±?3.58 and 1.49?±?2.89 ml/min/1.73 m2, respectively (p?=?0.015). Serum total cholesterol levels were 231?±?45 mg/dl and 196?±?42 mg/dl, respectively (two-sided p?=?0.064; one-sided p?=?0.032).

Conclusions

The presence of glomerular tip adhesions predicts the progression of IgA nephropathy. High levels of serum total cholesterol may affect glomerular tip adhesions.

     

Efficacy and safety of mycophenolate mofetil treatment in IgA nephropathy: a systematic review

Background

IgA nephropathy is the most common primary glomerular disease worldwide and also the most frequent cause of kidney failure. Mycophenolate mofetil (MMF) is a selective immunosuppressant widely used in many autoimmune diseases. However, the benefits and risks of MMF for the treatment of IgA nephropathy remain uncertain.

Methods

A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed to assess the efficacy and safety of MMF in IgA nephropathy patients, using the statistical software Review Manager 5.1.

Results

Eight RCTs involving 357 patients were identified and included in this review. Overall, no statistical difference was found in the therapeutic effect of MMF treatment compared with other therapies. MMF had no significant effects on reducing proteinuria or protecting renal function. However, subgroup analysis indicated that relatively short-term therapy (<18 months) might be beneficial in IgA nephropathy patients while longer term MMF use conferred no advantage. There was also no statistical difference between MMF and control groups in the incidence of side effects. When compared with other immunosuppressants, MMF was considered superior to cyclophosphamide in terms of better therapeutic effects and fewer adverse reactions, but no difference was found between MMF and leflunomide.

Conclusions

Our current evidence indicates that a relatively short course of MMF may be beneficial in treating IgA nephropathy. However, high-quality RCTs with large sample size as well as a well-designed study to evaluate the long-term effects of MMF are needed to further evaluate the efficacy and safety of MMF in this disease.

     

Hepatogener Diabetes

Background

Disturbances of glucose metabolism are common in chronic liver disease and about 30–40?% of patients with liver cirrhosis develop type 2 diabetes. The diabetes may be a direct consequence of the hepatic disease due to excessive insulin resistance or may be caused by classical type 2 diabetes.

Blood glucose determination

Patients with chronic liver disease frequently have a normal fasting glucose despite manifest type 2 diabetes with postprandial excessive increases in glucose. Therefore, oral glucose tolerance tests should be performed after diagnosis of hepatic cirrhosis.

Prognosis

Diabetes mellitus is associated with increased mortality and an increased risk of complications of liver cirrhosis including premature death, hepatocellular carcinoma, hepatic encephalopathy, and spontaneous bacterial peritonitis. Therapy of diabetes should include metformin and α?glucosidase inhibitors which can reduce the risk of these complications. Therefore, the diagnosis of diabetes has important consequences in chronic liver disease.

     

Cystatin C Is a Gender-Neutral Glomerular Filtration Rate Biomarker in Patients with Cirrhosis

Background

Lower serum Cr levels in women as compared to men result in underestimation of renal dysfunction and lower model for end-stage liver disease-sodium scores leading to reduced access to liver transplantation in women compared to men with comparable hepatic dysfunction.

Aim

The aim of this study was to determine the gender differences in serum Cr, cystatin C, and other endogenous glomerular filtration rate (GFR) biomarkers, measured and estimated GFR, Cr clearance, and Cr production rates.

Methods

We measured GFR by iothalamate plasma clearance in 103 patients with cirrhosis and assessed gender differences in GFR, Cr clearance and production rate, serum Cr, cystatin C and other endogenous GFR biomarkers including beta-trace protein, beta-2 microglobulin, and dimethylarginines.

Results

Comparison of men and women showed significantly lower values for mean serum Cr (0.97 vs. 0.82 mg/dl, P = 0.023), and Cr production rate (13.37 vs. 11.02 mg/kg/day, P = 0.022). In contrast to the serum Cr and Cr production rate, men and women exhibited no significant differences in the means of serum cystatin C and other GFR biomarkers, measured GFR, GFR estimated using Cr–cystatin C GFR equation for cirrhosis, measured and estimated Cr clearances. After controlling for age, race, weight, height, and GFR, female gender remained associated with lower serum Cr levels (P = 0.003). Serum cystatin C levels were not associated with gender, age, race, weight, height, C-reactive protein, and history of hypothyroidism.

Conclusions

Our results suggest that cystatin C and endogenous GFR biomarkers other than Cr, measured GFR, GFR estimated by Cr–cystatin C GFR equation for cirrhosis, measured and estimated Cr clearance minimized between-gender biases in accounting for renal function in patients with cirrhosis. Therefore, serum cystatin C should be measured as a complementary test to serum Cr when renal function is assessed in patients with cirrhosis, particularly in women and those with sarcopenia.

     

Transjugular liver biopsy in severe alcoholic hepatitis

Background

Alcoholic hepatitis and cirrhosis although part of spectrum of alcoholic liver disease can have overlapping features, and differentiating them using clinical, biochemical, and imaging features is not always possible. Standard therapy for each differs, and steroid therapy while beneficial in alcoholic hepatitis may be detrimental in cirrhosis due to high infectious complications. We analyzed our experience with liver biopsy in patients with severe alcoholic hepatitis.

Methods

Male patients in the age group of 25–65 years who were clinically diagnosed with severe alcoholic hepatitis (DF > 32) were retrospectively analyzed and included in this study. All of them had undergone transjugular liver biopsy within the first 7 days of hospitalization.

Results

Thirty patients were included. Most were in the 35–55 age group. Jaundice was present in all patients with fever and tender hepatomegaly also being common. On histopathological evaluation, 33.3% (n = 10) suspected clinically to have alcoholic hepatitis had underlying cirrhosis.

Conclusion

Cirrhosis is found in one third of patients with severe alcoholic hepatitis. This may alter our approach to management of this condition.

     

Hepatitis delta infection in Italian patients: towards the end of the story?

Background

The endemicity of hepatitis delta virus infection in Italy has decreased in the last decades.

Aim

To evaluate the current epidemiology of chronic delta infection in Italy and to compare the present findings with the corresponding figures from the previous studies.

Methods

A cross-sectional study involving 16 referral centres scattered all over the country in 2014.

Results

Out of the 513 hepatitis B surface antigen-positive subjects enrolled, 61 (11.9%) were anti-delta positive, with a sex ratio (M/F) of 2.05. The majority (80.3%) of them was 50 years or older, while the proportion of subjects younger than 30 years of age was as low as 3.3%. No difference was detected by geographical area of residence. The presence of liver cirrhosis was diagnosed in 52.4% of cases. In comparison to previous studies, a further shift towards the oldest age groups and an increasing proportion of subjects having liver cirrhosis among all anti-delta-positive subjects are observed.

Conclusions

Currently, hepatitis delta infection mostly affects old people who have an advanced but indolent liver disease, reflecting a survival effect. The defective hepatitis delta virus is near to disappear in the country, where it has been discovered in the second half of 70s.

     

The Portosystemic Shunt Syndrome and Role of Shunt Embolization in the Management of Hepatic Encephalopathy

Purpose of Review

Portosystemic shunting (PSS) is a result of changes in hepatic hemodynamics where portal flow diverts away from the liver due to increased intrahepatic resistance from cirrhosis and is associated with hepatic encephalopathy (HE). Over time, increased PSS may directly lead to worsening liver failure because of severely decreased loss of effective portal inflow towards the liver and result in recurrent or persistent HE. This clinical scenario has been recently defined as “portosystemic shunt syndrome” and has been associated with poor clinical outcomes.

Recent Findings

The presence of PSS is common in patients with cirrhosis and increased PSS size appears to correlate with recurrent or persistent HE. Recent studies have shown that patients with Model for End-Stage Liver Disease (MELD) score <?11 have demonstrated high clinical benefit in recurrent or persistent HE when treated with shunt embolization.

Summary

There is a growing literature that demonstrates potential clinical benefit using PSS embolization for selected patients, particularly with MELD under 11, with recurrent or persistent HE. Further investigation into improved risk stratification in order to determine effective treatments is necessary as well as heightened detection of the portosystemic shunt syndrome in its earlier and possibly reversible stages.

     

Non-HFE iron overload as a surrogate marker of disease severity in patients of liver cirrhosis

Background

Decompensated liver cirrhosis is an important cause of mortality worldwide. Various modifiable and non-modifiable factors are involved in the pathogenesis of cirrhosis and its complications. This study was aimed to evaluate the association of iron overload and disease severity in patients of liver cirrhosis and its association with HFE gene mutation.

Methods

Forty-nine patients with decompensated liver cirrhosis were recruited. Clinical and laboratory parameters were compared in patients with and without iron overload. C282Y and H63D gene mutation analysis was performed in all patients with iron overload.

Results

Iron overload was found in 20 (40.82 %) patients. A significant positive correlation of transferrin saturation with Child-Turcotte-Pugh (CTP) score (r?=?0.705, p?<?0.001) and model for end-stage liver disease (MELD) score (r?=?0.668, p?<?0.001) was found. Transferrin saturation was also independently associated with high CTP and MELD score on multivariate analysis. Mortality over 3 months was significantly more common in iron-overloaded patients (p?=?0.028). C282Y homozygosity or C282Y/H63D compound heterozygosity was not found in any of the patients with iron overload.

Conclusion

Iron overload was significantly associated with disease severity and reduced survival in patients of decompensated liver cirrhosis.

     

Prevalence of celiac disease among pediatric patients with cryptogenic cirrhosis and effect of gluten-free-diet

Background

Liver involvement in celiac disease (CD) is classified into autoimmune and cryptogenic. The association between CD and autoimmune liver diseases like autoimmune hepatitis, primary biliary cirrhosis, and primary sclerosing cholangitis is well-established; however, the data on patients with cryptogenic cirrhosis, particularly from India, are scanty. So we did this study to find the prevalence of CD in patients with cryptogenic cirrhosis.

Methods

This was a prospective observational study, involving children of less than 18 years old attending Pediatric and Gastroenterology clinic with a diagnosis of cryptogenic cirrhosis. The patients were evaluated for CD and divided into two groups: chronic liver disease (CLD) with CD, and CLD without CD. Both the groups were followed up for 6 months. CLD with CD group was treated with gluten-free-diet (GFD) and CLD without CD group was followed up without any specific intervention except standard care of CLD.

Results

Out of 84 patients, 11 (13.1%) were diagnosed as CLD with CD. There was an improvement in hemoglobin levels, liver function tests, and Child-Pugh score after initiation of GFD in CLD with CD group.

Conclusion

The prevalence of CD in cryptogenic cirrhosis was 13.1%. Screening for CD is recommended for cryptogenic cirrhosis. Hepatic functions improve with a GFD in CD patients with cirrhosis.

     

Nichtalkoholische Steatohepatitis und ihre Folgen

Background

The prevalence of nonalcoholic fatty liver disease (NAFLD) continues to increase. An estimated 25?% of the adult population worldwide and more than 50?% of patients with type 2 diabetes or obesity have NAFLD.

Objectives

An overview of the natural history and complications of NAFLD is provided.

Materials and methods

Following an extensive literature research, the current guidelines, expert opinions and studies focusing on NAFLD were analyzed.

Results

The term NAFLD includes the entities nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH), which are defined by histological parameters. Importantly, “benign” NAFL may progress towards more aggressive NASH with the development of liver fibrosis. The grade of fibrosis is the most important predictor for overall and liver-related mortality in NAFLD patients and patients suffering from type 2 diabetes mellitus have a higher risk for progressive fibrosis. Progressive NAFLD can develop into liver cirrhosis with the potential of fatal complications of portal hypertension and liver failure. Notably, hepatocellular carcinoma may also develop in noncirrhotic NAFLD. Furthermore, NAFLD is an independent risk factor for cardiovascular disease and extrahepatic malignancy, which represent the two most frequent causes of death in NAFLD patients. To date, a lifestyle intervention aiming at weight reduction and increased physical activity is the first-line therapy for NAFLD.

Conclusions

NAFLD is one of the most common liver diseases and is associated with relevant hepatic and extrahepatic morbidity and mortality.

     

Role of Non-hepatic Medical Comorbidity and Functional Limitations in Predicting Mortality in Patients with HCV

Background

Medical comorbidities and functional status limitations are determinants of mortality in many chronic diseases. The extent to which survival in the rapidly aging cohort of patients with HCV is affected by these competing causes of mortality remains unclear.

Aim

We sought to determine the effect of medical/functional comorbidities on survival after adjusting for liver disease severity in a cohort of patients with HCV infection.

Methods

We prospectively recruited consecutive patients from an HCV clinic 2009–2014. We calculated an index of survival (Schonberg Index, SI) based on age, gender, medical comorbidities, and functional status variables. We defined cirrhosis with the FibroSure test (F3/4–F4). We used multivariable Cox modeling to assess association between functional/survival measure and survival after adjustment for severity of liver disease.

Results

The cohort consisted of 1052 HCV patients. The average age was 56.8 years; 36 % had cirrhosis. The mean SI was 8.2 (SD = 2.7). During a mean follow-up of 5610 person-years, 102 (9.7 %) patients died. In unadjusted analysis, higher baseline SI predicted mortality (HR 1.17; 95 % CI 1.09–1.25). SI similarly predicted mortality in cirrhotic patients (HR 1.23, 95 % CI 1.13–1.34) and non-cirrhotic patients (HR 1.21, 95 % CI 1.08–1.36). This did not change after adjusting for age, drug use, or coronary artery disease.

Discussion

Comorbidities and functional limitations predict higher mortality in patients with HCV; this relationship is independent of cirrhosis. Use of general prognostic indices may help identify HCV patients at high risk for mortality, which could further guide clinical care in a manner not achievable with assessment of liver disease alone.

     

Complement 5a is an indicator of significant fibrosis and earlier cirrhosis in patients chronically infected with hepatitis B virus

Purpose

To investigate the association between serum complement 5a (C5a) concentration and liver fibrosis and cirrhosis in a large cohort of patients chronically infected with hepatitis B virus (HBV).

Methods

Five hundred and eight patients with chronic HBV infection undergoing liver biopsy were included. Serum concentrations of C5a was measured by Luminex screening system. Ishak histological system was obtained.

Results

C5a levels were negatively associated with liver fibrosis stages and significantly declined in patients with severe fibrosis and cirrhosis (P < 0.001). Multiple analysis showed C5a, AST, laminin, Co-IV, platelet count, albumin, HBsAg associated with liver fibrosis independently. Based on the markers above, we created two scores, Fib-model for significant fibrosis and Cirrh-model for earlier cirrhosis. Fib-model was performing better to differentiate from significant fibrosis, with an AUROC of 0.82 (95 % CI 0.78, 0.86), in comparison to existed models APRI, FIB-4 and Forns’ index with AUROCs of 0.71 (95 % CI 0.66, 0.76), 0.72 (95 % CI 0.67, 0.77), 0.77 (95 % CI 0.72, 0.81), respectively. Although, Cirrh-model showed AUROC of 0.85 (95 % CI 0.80, 0.91) for evaluation of earlier cirrhosis, superior to APRI, and Forns’ index, C5a + FIB-4 performed best with an AUROC of 0.94 (95 % CI 0.90, 0.97).

Conclusion

In patients with chronic HBV infection, serum C5a concentration significantly decreased in severe fibrosis stages and earlier cirrhosis. Fib-model and C5a + FIB-4 performed better than existed models for assessment of significant fibrosis and earlier cirrhosis, respectively.

     

Hospital Cirrhosis Volume and Readmission in Patients with Cirrhosis in California

Background

Patients with cirrhosis are at high readmission risk. Using a large statewide database, we evaluated the effect of hospital cirrhosis-related patient volume on 30-day readmissions in patients with cirrhosis.

Methods

We conducted a retrospective study of the Healthcare Cost and Utilization Project State Inpatient Database for adult patients with cirrhosis, as defined by International Classification of Diseases, Ninth Revision (ICD-9) codes, hospitalized in California between 2009 and 2011. Multivariable logistic regression analysis was performed to evaluate the effect of hospital volume on 30-day readmissions.

Results

A total of 69,612 patients with cirrhosis were identified in 405 hospitals; 24,062 patients were discharged from the top 10% of hospitals (N = 41) by cirrhosis volume, and 45,550 patients in the bottom 90% (N = 364). Compared with higher-volume centers, lower-volume hospitals cared for patients with similar average Quan–Charlson–Deyo (QCD) comorbidity scores (6.54 vs. 6.68), similar proportion of hepatitis B and fatty liver disease, lower proportion of hepatitis C (34.8 vs. 41.5%) but greater proportion of alcoholic liver disease (53.1 vs. 47.4%). Multivariable logistic regression analysis demonstrated admission to a lower-volume hospital did not predict 30-day readmission (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.92–1.01) after adjusting for sociodemographics, QCD score, cirrhosis severity, and hospital characteristics. Instead, liver transplant center status significantly decreased the risk of readmission (OR 0.87, 95% CI 0.80–0.94). Ascites, hepatic encephalopathy, hepatocellular carcinoma, higher QCD, and presence of alcoholic liver disease and hepatitis C were also independent predictors.

Conclusions

Readmissions within 30 days were common among patients with cirrhosis hospitalized in California. While hospital cirrhosis volume did not predict 30-day readmissions, liver transplant center status was protective of readmissions. Medically complicated patients with cirrhosis at hospitals without liver transplant centers may benefit from additional support to prevent readmission.

     

Fettleberdiagnostik bei Diabetes mellitus Typ 2

Definition of terms

Under the term non-alcoholic fatty liver disease (NAFLD) both simple hepatic fat accumulation and non-alcoholic steatohepatitis (NASH) are combined. NASH is associated with liver fibrosis, cirrhosis and hepatocellular carcinoma (HCC).

Epidemiological importance

In 2020, NAFLD will be the leading cause for liver transplantation in the USA, with rising financial costs for the healthcare system.

Comorbidities, diagnosis, and treatment

Type 2 diabetes (T2D) and metabolic syndrome (MetS) are important risk factors for the development of NAFLD, whereby these three diseases share similar pathophysiologic conditions, e.g., insulin resistance, obesity, and metabolic inflammation. Due to the rising number of patients with T2D and MetS, clinicians should aim to diagnose NAFLD early in this patient population and if necessary start treatment.

Goal

The aim of this work is to give an overview over the topic of NAFLD and diagnostic approaches in patients with T2D.

     

Diabetestherapie bei nichtalkoholischer Fettlebererkrankung

Background

Nonalcoholic fatty liver disease (NAFLD) is defined by hepatocellular fat accumulation of more than 5?% (fatty liver, NAFL, steatosis) and also comprises steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma. No specific drug treatment for NAFLD in type 2 diabetes mellitus (T2D) is approved.

Methods

In a Medline search, randomized controlled trials on weight- and/or blood glucose-lowering therapies in NAFLD and T2D with the primary endpoints reduction of liver fat content and/or improvement in liver histology were identified.

Results

Lifestyle modification (weight loss of >7?%) and bariatric surgery reduce inflammation and hepatocellular ballooning in NASH. Pioglitazone therapy can improve inflammation and ballooning in prediabetes or T2D within 6 months. This effect remains for at least 3 years. Liraglutide results in reduction of liver fat content and improvement of inflammation and ballooning in NASH, with fewer liraglutide-treated individuals showing an aggravation of fibrosis. Metformin, sulfonylureas and insulin have no clinically relevant effect on liver fat content and liver histology.

Conclusions

Beyond lifestyle modification, the benefit of pioglitazone, liraglutide and bariatric surgery for reduction of liver fat content and NASH must be balanced against the risks and costs. Further specific therapeutic recommendations will require studies on novel drugs and longer-term controlled prospective trials.

     

Very Low Viral Load (VLVL) Relapse Following Treatment of Naïve Patients with Chronic Hepatitis C

Background

Sustained virologic response (SVR) to treatment of naïve patients with chronic hepatitis C (HCV) with pegylated interferon and ribavirin is 50–60%. Patients who relapse have a poor response to re-treatment. We report a group of relapse patients with SVR to low-dose re-treatment after 6 months.

Aim

Characterization of HCV relapse patients with very low viral load (VLVL) (HCV RNA <5,000 IU/ml) 6 months after stopping full-dose initial treatment.

Methods

We identified 120 consecutive naïve patients over 4 years treated with pegylated interferon alpha-2a and ribavirin with full-dose therapy for 24 weeks (non-genotype 1) or 48 weeks (genotype 1) with baseline liver biopsy and at least 6 months of follow-up after treatment. HCV RNA by PCR and hepatic blood tests were obtained monthly during treatment and at least 1, 3, and 6 months post treatment.

Results

Of the initially treated patients, 54.2% had SVR, 25% non-response and 20.8% relapsed. Four of 25 who relapsed (16%) and one similar patient referred to our program had HCV RNA <5,000 IU/ml 6 months after stopping treatment (VLVL relapse). Significant differences (P < 0.05) compared with the 21 other relapse patients included all five patients who were genotype 1; 4/5 had cirrhosis, baseline HCV RNA was lower, and all had SVR to less intensive re-treatment for 6 months.

Conclusion

VLVL relapse patients should be sought, because SVR to re-treatment is common despite genotype 1 cirrhosis.

     

Transplantation sites for porcine islets

Aims/hypothesis

Xenotransplantation has great potential to provide beta cell replacement and thereby provide a cure for large numbers of people with type 1 diabetes. Crucial to the success of xenotransplantation is establishment of the most viable sites for transplantation.

Methods

We compared porcine islet tissue transplanted into kidney, liver and spleen in pig recipients as assessed by blood glucose levels and IVGTT.

Results

Kidney was the superior site for porcine islet tissue transplantation, followed by liver then spleen. This was demonstrated by IVGTTs showing significant difference between the peak glucose levels: 22.8 ± 2.9 mmol/l for kidney compared with 26.8 ± 1.3 mmol/l for spleen and 24.7 ± 1.7 mmol/l for liver.

Conclusions/interpretation

Kidney grafts are not as feasible in humans and liver results were relatively poorer than spleen. For islet transplantation to be viable and successful in the longer term, there remains a need for future investigation of alternative sites.

     

Non-variceal upper gastrointestinal bleeding in cirrhotic patients in Nile Delta

Background and Study Aims

Acute upper gastrointestinal bleeding (AUGIB) in cirrhotic patients occurs mainly from esophageal and gastric varices; however, quite a large number of cirrhotic patients bleed from other sources as well. The aim of the present work is to determine the prevalence of non-variceal UGIB as well as its different causes among the cirrhotic portal hypertensive patients in Nile Delta.

Methods

Emergency upper gastrointestinal (UGI) endoscopy for AUGIB was done in 650 patients. Out of these patients, 550 (84.6 %) patients who were proved to have cirrhosis were the subject of the present study.

Results

From all cirrhotic portal hypertensive patients, 415 (75.5 %) bled from variceal sources (esophageal and gastric) while 135 (24.5 %) of them bled from non-variceal sources. Among variceal sources of bleeding, esophageal varices were much more common than gastric varices. Peptic ulcer was the most common non-variceal source of bleeding.

Conclusions

Non-variceal bleeding in cirrhosis was not frequent, and sources included peptic ulcer, portal hypertensive gastropathy, and erosive disease of the stomach and duodenum.

     

Microwave ablation of hepatocellular carcinoma with portal vein tumor thrombosis after transarterial chemoembolization: a prospective study

Aims

To prospectively assess the use of microwave ablation (MWA) to treat hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) after transarterial chemoembolization (TACE), and to evaluate factors that significantly affect treatment outcomes.

Methods

Sixty patients with HCC [55 male, 5 female; mean age, 54.1 ± 10.2 (range 36–77) years] + PVTT were enrolled. Patients were treated with MWA after TACE. Results were compared with those of 54 patients treated by TACE alone in another retrospective study. Data analyzed included patient demographics, Eastern Cooperative Oncology Group performance status, liver cirrhosis, liver volume, Child-Pugh class, Cancer of the Liver Italian Program (CLIP) score, and imaging findings. Survival time (from occurrence of PVTT to last follow-up) and predictive factors and their correlation with survival were statistically evaluated.

Results

The median 3-year overall survival (OS) duration was 13.5 months, and the 1- and 3-year OS rates were 48 and 23 %, respectively. Cox hazards regression analysis revealed that change in the neutrophil-to-lymphocyte ratio, CLIP score, and treatment efficacy were the only independent predictive factors for outcome (p = 0.035, 0.024, and 0.000, respectively).

Conclusions

Combination therapy with MWA after TACE may provide a substantial benefit for patients with HCC + PVTT type I, II, or partial III and Child-Pugh class A or B by reducing the tumor burden.

Portale Hypertension: Varizen

Background

Variceal hemorrhage is a major cause of morbidity and mortality in patients with cirrhosis. However, mortality rates have been substantially reduced in recent years due to improved diagnostic and therapeutic workup.

Therapy

Patients who present with active variceal hemorrhage require immediate hemodynamic resuscitation and early upper gastrointestinal endoscopy. Endoscopic variceal ligation (EVL) is the treatment of choice for esophageal varices, whereas cyanoacrylate injection is preferably used for the treatment of gastric varices. If endoscopic therapy fails to control bleeding, balloon tamponade or stent placement may be required. Emergency transjugular intrahepatic portosystemic shunt (TIPS) placement is a more definite option, when available.

Prophylaxis

For primary prophylaxis of variceal hemorrhage, treatment with a nonselective beta blocker or EVL is recommended whereas a combination of the two is recommended for secondary prophylaxis.
