A Phase II Randomized, Controlled Trial of S-Adenosylmethionine in Reducing Serum α-Fetoprotein in Patients with Hepatitis C Cirrhosis and Elevated AFP.

In animal models of hepatocellular carcinoma (HCC), deficiency of S-adenosylmethionine (SAMe) increased the risk of HCC whereas administration of SAMe reduced HCC. The aim of this trial was to determine whether oral SAMe administration to patients with hepatitis C cirrhosis would decrease serum α-fetoprotein (AFP) level, a biomarker of HCC risk in hepatitis C. This was a prospective, randomized, placebo-controlled, double-blind trial of SAMe, up to 2.4 g/d, for 24 weeks as compared with placebo among subjects with hepatitis C cirrhosis and a mildly elevated serum AFP. Primary outcome was change in AFP between baseline and week 24. Secondary outcomes included changes in routine tests of liver function and injury, other biomarkers of HCC risk, SAMe metabolites, markers of oxidative stress, and quality of life. One hundred ten subjects were randomized and 87 (44 SAMe and 43 placebo) completed treatment. There was no difference in the change in AFP during 24 weeks among subjects receiving SAMe as compared with placebo. Changes in markers of liver function, liver injury, and hepatitis C viral level were not significantly different between groups. Similarly, SAMe did not change markers of oxidative stress or serum glutathione level. SAMe blood level increased significantly among subjects receiving SAMe. Changes in quality of life did not differ between groups. Overall, this trial did not find that SAMe treatment improved serum AFP in subjects with advanced hepatitis C cirrhosis and a mildly elevated AFP. SAMe did not improve tests of liver function or injury or markers of oxidative stress or antioxidant potential.

Proactive case finding to improve concurrently curative and palliative care in patients with end-stage liver disease.

BACKGROUND: Palliative care and preparation for liver transplantation are often perceived as conflicting for patients with end-stage liver disease (ESLD). We sought to improve both simultaneously through a case finding and care coordination quality improvement intervention. METHODS: We identified patients with cirrhosis using validated ICD-9 codes and screened them for ESLD by assessing medical records at a VA hospital for either a model for end-stage liver disease (MELD) ≥14 or a diagnosis of hepatocellular carcinoma (HCC) between October 2012 and January 2013. A care coordinator followed veterans from the index hospitalization through April 2013 and encouraged treating physicians to submit liver transplant evaluation consults for all veterans with a MELD ≥14 and palliative care consults for all veterans with a MELD ≥20 or inoperable HCC. RESULTS: We compared rates of consultation for 49 hospitalized veterans and compared their outcomes to 61 pre-intervention veterans. Veterans were more likely to be considered for liver transplantation (77.6% versus 31.1%, p<0.001) and receive palliative care consultation during the intervention period, although the latter finding did not reach statistical significance (62.5% versus 47.1%, p=0.38). CONCLUSIONS: Active case finding improved consideration for liver transplantation without decreasing palliative care consultation.

Recommendations for the diagnosis and treatment of the acute porphyrias.

The acute porphyrias, 4 inherited disorders of heme biosynthesis, cause life-threatening attacks of neurovisceral symptoms that mimic many other acute medical and psychiatric conditions. Lack of clinical recognition often delays effective treatment, and inappropriate diagnostic tests may lead to misdiagnosis and inappropriate treatment. We review the clinical manifestations, pathophysiology, and genetics of the acute porphyrias and provide recommendations for diagnosis and treatment on the basis of reviews of the literature and clinical experience. An acute porphyria should be considered in many patients with unexplained abdominal pain or other characteristic symptoms. The diagnosis can be rapidly confirmed by demonstration of a markedly increased urinary porphobilinogen level by using a single-void urine specimen. This specimen should also be saved for quantitative measurement of porphobilinogen, 5-aminolevulinic acid, and total porphyrin levels. Intravenous hemin therapy, started as soon as possible, is the most effective treatment. Intravenous glucose alone is appropriate only for mild attacks (mild pain, no paresis or hyponatremia) or until hemin is available. Precipitating factors should be eliminated, and appropriate supportive and symptomatic therapy should be initiated. Prompt diagnosis and treatment greatly improve prognosis and may prevent development of severe or chronic neuropathic symptoms. We recommend identification of at-risk relatives through enzymatic or gene studies.

Acute pancreatitis associated with interferon and ribavirin therapy in patients with chronic hepatitis C.

Acute pancreatitis is a rare complication of interferon (IFN) and ribavirin (RBV) therapy. The aim of this study was to determine the incidence, clinical presentation, and outcome of acute pancreatitis in patients with chronic hepatitis C virus (HCV) infection treated with IFN and RBV combination therapy. We conducted a retrospective review of 1706 HCV-infected patients treated with IFN alpha-2b and RBV. The diagnosis of drug-induced acute pancreatitis was made based on the presence of epigastric pain, elevated amylase and lipase levels, and the absence of other identifiable causes of pancreatitis. Acute pancreatitis was diagnosed in 7 of 1706 HCV-infected patients (0.4%; 95% CI, 0.2 to 0.8%) who were treated with IFN alpha-2b and RBV. The mean age of the patients (four males and three females) was 51.4 +/- 4.7 years and the median duration of therapy prior to development of pancreatitis was 12.0 weeks (range, 4.0-21.0 weeks). All patients presented with epigastric pain associated with nausea, vomiting, and/or fever. The median amylase and lipase values at the time of diagnosis of pancreatitis were 330.0 U/L (range, 182.0-1813.0 U/L) and 500.0 U/L (range, 171.0-2778.0 U/L), respectively. IFN and RBV were discontinued in all patients at the time of diagnosis and six of the seven patients were hospitalized; one patient refused hospital admission. Pancreatitis resolved in all seven patients and none of these individuals had recurrent pancreatitis during a median follow-up of 18.0 months (range, 3.0-27.0 months). In conclusion, IFN and RBV combination therapy is a potential cause of drug-induced pancreatitis in patients with chronic HCV. In these individuals, pancreatitis is often severe enough to warrant hospital admission, although symptoms resolve promptly after discontinuation of antiviral therapy.
