Do Hepatic Encephalopathy Patients Really Need a Low Protein in Their Diet

Hepatic encephalopathy (HE) is an extra hepatic complication of liver cirrhosis. The clinical manifestation of HE is a reflection of a low-grade cerebral edema due to astrocyte swelling as a consequence of hyperammonia. HE mostly is induced by precipitating factors. Correcting these identifiable precipitating factors can alleviate this complication. In the past, liver cirrhosis patients were recommended to lower their protein intake. It was assumed that by limiting protein intake, the ammonia production would lower, which can lead to HE recovery. This approach, on the other hand, had worsened the nutritional status that already present in most patients with HE. There are some ways to overcome these problems without restricting protein intake including balance diet, using Branch Chain Amino Acids (BCAA), and frequent small portion diet

Alpha-1-acid glycoprotein as potential biomarker for alpha-fetoprotein-low hepatocellular carcinoma

<p>Abstract</p> <p>Background</p> <p>The outcome of patients with hepatocellular carcinoma (HCC) remains poor because of late diagnosis. We determined the performances of α -1-acid glycoprotein (AAG) and des-γ-carboxy prothrombin (DCP) for the diagnosis of HCC, especially for α-fetoprotein (AFP)-low HCC.</p> <p>Methods</p> <p>Of the 220 patients included in this retrospective study, 124 had HCC, and 61 (49%) of these were AFP-low HCC (AFP ≤ 20 ng/mL). The remaining 96 patients, including 49 with chronic hepatitis B or C and 47 with cirrhosis, were considered as control. Plasma AAG was analyzed using high performance liquid chromatography (HPLC) and confirmed using Western blot technique.</p> <p>Results</p> <p>When all patients with HCC were evaluated, the area under receiver operating characteristic (ROC) curves for AAG (0.94, 95% CI: 0.91-0.97) and DCP (0.92, 95% CI: 0.88-0.95) were similar (<it>P </it>= 0.40). AAG had better area under ROC curve (0.96, 95% CI: 0.94-0.99) than DCP (0.87, 95% CI: 0.81-0.93) for AFP-low HCC (<it>P </it>< 0.05). At the specificity 95%, the sensitivity of AAG was higher in AFP-low HCC than in AFP-high HCC (82% and 62%, respectively). In contrast, higher sensitivity was obtained from DCP in discriminating HCC patients with low AFP than that in high AFP (57% and 90%, respectively).</p> <p>Conclusion</p> <p>Our cross-sectional study showed that AAG was better performance in diagnosing HCC patients with low AFP, while DCP did better in those with high AFP.</p
