Chylous ascites as the main manifestation of left ventricular dysfunction: a case report

BACKGROUND: Ascites is one of the most common complications of liver diseases, even though in 15% of the cases it is related to extrahepatic diseases; 3% are of cardiac nature and they appear associated with signs and symptoms of heart failure. CASE PRESENTATION: A 70 year old man was admitted with more than one year history of abdominal distension and a weight gain of 10 kilograms. He is asymptomatic and walks 2000–3000 meters a day without angor or dyspnea. The physical examination shows moderate abdominal distension, with no hepatosplenomegaly or edema, and there is mild jugular vein distension. The studies performed (complete laboratory work up, paracentesis, liver biopsy, echocardiogram, intrahepatic pressure measurements, etc.) showed a chylous ascites related to portal hypertension, and left ventricular dysfunction was the only probable cause found. CONCLUSION: Asymptomatic heart dysfunction can mimic liver disease and should be kept in mind as a cause of chylous ascites

Short and long term outcome of kidney transplanted patients with chronic viral hepatitis B and C

Introduction. Liver disease related to chronic viral hepatitis is a major cause of morbidity and mortality in renal transplant patients. There is no agreement upon the influence of chronic hepatitis B (HBV) and hepatitis C (HCV) infection in patient and graft survival.Aims. The aim of the study was to evaluate the influence of HBV and HCV on patient and graft short and long term survival, in the patients transplanted at our institution.Materials and methods. We evaluated the influence of antiHCV and HBsAg status (positive vs. negative); sex; age (> 49 years vs. 3 vs. < 3 years); acute rejection; kind of graft (deceased vs. living donor, and kidney versus kidney and pancreas); number of transplantations; use of induction immunosuppression; and maintenance immunosuppression treatment (comparing the traditional triple therapy containing azathioprine, cyclosporine and prednisone vs. newer regimens which include tacrolimus, mycophenolate mofetil, sirolimus, etc) on the survival, long term and within the first month of transplantation, of the graft and the patients transplanted in our Institution between January 1991 and August 2009.Results. We included 542 patients, 60% males’ median age of 42.03 years (SD 13.06 years). 180 patients (33%) were antiHCV positive and 23 (4%) were HBsAg positive. AntiHCV positive, traditional triple therapy and acute rejection were associated with diminished graft survival. Older age, antiHCV positive, HBsAg positive, deceased donor, kidney-pancreas transplantation and traditional triple therapy were associated with diminished patient survival. Traditional triple therapy was associated with diminished one month graft survival; and older age and antiHCV positive were associated with diminished one month patient survival.Conclusion. In our experience, antiHCV positive status was associated with diminished long term patient and graft survival, and diminished six month graft survival; and HBsAg positive was associated with diminished patient survival

Genetic variation in interleukin-28B predicts SVR in hepatitis C genotype 1 Argentine patients treated with PEG IFN and ribavirin

BACKGROUND AND AIMS: Genetic variations in the interleukin 28B (IL28B) gene have been associated with viral response to PEG-interferon-α/ribavirin (PR) therapy in hepatitis C virus (HCV) genotype 1 infected patients from North America, Europe and Asia. The importance of these IL28B variants for Argentine patients remains unknown. MATERIAL AND METHODS: IL28B host genotypes (rs8099917 and rs12979860) were determined in a population of Argentine patients with European ancestry. Results were analyzed looking for their association with sustained virologic response (SVR) to PR therapy and compared with other baseline hosts' biochemical, histological and virological predictors of response. RESULTS: We studied 102 patients, 60% were men, and 40% of them were rs8099917 TT and 18% rs12979860 CC. Mean baseline serum HCV RNA was 1.673.092 IU/mL and mean F score was: 2.10 ± 1.18 (21% cirrhotic). SVR rate was higher in rs8099917 TT genotypes (55%) when compared to GT/GG (25%) (p = 0.002) and in rs1512979860 CC (64%) than in CT/TT (30%) (p = 0.004). The univariate analysis showed that rs8099917 TT (OR 3.7; 95 %CI 1.5-8.7; p = 0.002), rs12979860 CC (OR 4.6; 95%CI 1.5-13.7; p = 0.006), low viral load (OR 4.6; 95% CI 1.7-12.6; p = 0.002) and F0-2 (OR 8.5; 95% CI 2.3-30.6; p = 0.001) were significantly associated with SVR. In the multivariate analysis, rs12979860 CC, rs8099917 TT, viral load < 400.000 IU/mL and F0-2 were associated with SVR rates (p = 0.029, p = 0.012, p = 0.013 and p = 0.004, respectively). CONCLUSION: IL28B host genotypes should be added to baseline predictors of response to PR therapy in Latin American patients with European ancestry.Fil: Ridruejo, Ezequiel.

Ultra-sensitive procalcitonin may help rule out bacterial infections in patients with cirrhosis

Background. Bacterial infections are frequent complications in patients with cirrhosis. Since they are associated with poor outcomes, antibiotics are frequently over-prescribed. Surrogate markers of bacterial infections, like procalcitonin, are needed to better discriminate between infected and not infected patients.Aims. To evaluated the diagnostic accuracy of an ultra-sensitive procalcitonin assay for the diagnosis of bacterial infections in patients with cirrhosis.Material and methods. In a single-center prospective study, we determined the basal levels of procalcitonin in 106 episodes of admissions to the emergency department in 84 cirrhotic patients. Patients were classified as infected or not infected by two independent hepatologists blinded to the procalcitonin result.Results. The prevalence of bacterial infection was 28% (29 episodes). The median procalcitonin was significantly higher in the infected group than in the not infected group (0.45 vs. 0.061 ng/mL, p < 0.001). The diagnostic accuracy of procalcitonin for bacterial infection estimated by the ROC curve was 0.95 (CI: 95%, 0.91-0.99). When selecting a cutoff value of 0.098 ng/mL a sensitivity of 97% and a negative predictive value 98% were found.Conclusions. The use of an ultra-sensitive procalcitonin assay identifies patients with cirrhosis at very low risk of bacterial infections

Efficacy and safety of long term entecavir in chronic hepatitis B treatment naïve patients in clinical practice

Background and aims. Entecavir (ETV) is effective and safe in patients with chronic hepatitis B in the short term, but its long term efficacy and safety has not been established.Material and methods. We evaluated HBV DNA clearance, HBeAg/antiHBe and HBsAg/antiHBs seroconversion rates in HBeAg-positive and negative NUC naïve HBV patients treated with ETV for more than 6 months, and predictors of response.Results. A hundred and sixty nine consecutive patients were treated with ETV for a median of 181 weeks. 61% were HBeAg positive, 23% were cirrhotics, and mean HBV-DNA levels were 6,88 ± 1,74 log10 lU/mL. Overall, 156 (92%) patients became HBV DNA undetectable, 92 (88%) HBeAg positive and 64 (98%) HBeAg negative patients. Seventy four (71%) patients cleared HBeAg after a median of 48 weeks of treatment, 23 (14%) patients cleared HBsAg (19 HBeAg positive and 4 HBeAg negative, p 0.025) after a median of 96 weeks of treatment, and 22 (13%) patients developed protective titers of anti-HBs. At the end of the study, 35 (20%) patients had discontinued therapy: 33 HBeAg positive and 2 HBeAg negative; 9 of them (26%) developed virological relapse after a median of 48 weeks of stopping treatment. None of the patients had primary non response and one patient developed breakthrough. Two patients developed HCC, three underwent liver transplantation and 3 deaths were attributable to liver-related events. No serious adverse events were reported.Conclusion. Long term ETV treatment showed high virological response rates, and a favorable safety profile for NUC-naive HBeAg-positive and negative patients treated in clinical practice
