Single center analysis of therapy and outcomes of hepatocellular carcinoma in Sub-Saharan Africa.

PURPOSE: To evaluate the characteristics and response to therapy for HCC in sub-Saharan Africa. PATIENTS AND METHODS: We retrospectively evaluated demographic, clinical and outcome variables of HCC in a referral clinic in Ethiopia from 2016 to 2018. Survival assessment was performed using the Mann-Whitney test. Associations between categorical variables was assessed using Pearson Chi-square test. RESULTS: We report 46 HCC cases with a median age of 54 years (IQR 45-62) and 50% female. Viral hepatitis was the most common underlying etiology, with 41% of subjects infected with hepatitis B virus (HBV) and 45% with hepatitis C. The median MELD was 12 (IQR 8-17), we found no association between survival and a MELD score 15, regardless of underlying disease (pr=0.61, p>0.05). 31% of individuals underwent supportive treatment with a median survival of 27 days (IQR 19-181), 18% used Sorafenib (median survival of 94 days, IQR 24-121), and trans-arterial chemoembolization (TACE) was utilized in 16% (median survival of 352 days, IQR 30-436). HBV cases were diagnosed younger (31% before the age of 40) and those on Tenofovir had a longer median survival than those off Tenofovir (121 vs 34 days). CONCLUSION: Our study found that antiviral treatment of HBV infection was associated with longer survival in HCC. Furthermore, Sorafenib seemed beneficial in patients that used this modality and NLR was a good prognostic factor.

Incidence and Etiology of Drug-Induced Liver Injury in Mainland China.

BACKGROUND & AIMS: We performed a nationwide, retrospective study to determine the incidence and causes of drug-induced liver injury (DILI) in mainland China. METHODS: We collected data on a total of 25,927 confirmed DILI cases, hospitalized from 2012 through 2014 at 308 medical centers in mainland China. We collected demographic, medical history, treatment, laboratory, disease severity, and mortality data from all patients. Investigators at each site were asked to complete causality assessments for each case whose diagnosis at discharge was DILI (n = 29,478) according to the Roussel Uclaf Causality Assessment Method. RESULTS: Most cases of DILI presented with hepatocellular injury (51.39%; 95% confidence interval [CI] 50.76-52.03), followed by mixed injury (28.30%; 95% CI 27.73-28.87) and cholestatic injury (20.31%; 95% CI 19.80-20.82). The leading single classes of implicated drugs were traditional Chinese medicines or herbal and dietary supplements (26.81%) and antituberculosis medications (21.99%). Chronic DILI occurred in 13.00% of the cases and, although 44.40% of the hepatocellular DILI cases fulfilled Hy's Law criteria, only 280 cases (1.08%) progressed to hepatic failure, 2 cases underwent liver transplantation (0.01%), and 102 patients died (0.39%). Among deaths, DILI was judged to have a primary role in 72 (70.59%), a contributory role in 21 (20.59%), and no role in 9 (8.82%). Assuming the proportion of DILI in the entire hospitalized population of China was represented by that observed in the 66 centers where DILI capture was complete, we estimated the annual incidence in the general population to be 23.80 per 100,000 persons (95% CI 20.86-26.74). Only hospitalized patients were included in this analysis, so the true incidence is likely to be higher. CONCLUSIONS: In a retrospective study to determine the incidence and causes of DILI in mainland China, the annual incidence in the general population was estimated to be 23.80 per 100,000 persons; higher than that reported from Western countries. Traditional Chinese medicines, herbal and dietary supplements, and antituberculosis drugs were the leading causes of DILI in mainland China.

Nutrition therapy: Integral part of liver transplant care.

Managing malnutrition before liver transplantation (LTx) while on the waiting list and, excessive weight gain/metabolic disturbances in post-surgery are still a challenge in LTx care. The aim of this review is to support an interdisciplinary nutrition approach of these patients. Cirrhotic patients are frequently malnourished before LTx and this is associated with a poor prognosis. Although the relation between nutritional status versus survival, successful operation and recovery after LTx is well established, prevalence of malnutrition before the operation is still very high. Emerging research has also demonstrated that sarcopenia pre and post-transplant is highly prevalent, despite the weight gain in the postoperative period. The diagnosis of the nutritional status is the first step to address the adequate nutritional therapy. Nutritional recommendations and therapy to manage the nutritional status of LTx patients are discussed in this review, regarding counseling on adequate diets and findings of the latest research on using certain immunonutrients in these patients (branched chain amino-acids, pre and probiotics). Nutrition associated complications observed after transplantation is also described. They are commonly related to the adverse effects of immunosuppressive drugs, leading to hyperkalemia, hyperglycemia and weight gain. Excessive weight gain and post-transplant metabolic disorders have long been described in post-LTx and should be addressed in order to reduce associated morbidity and mortality.

Effects of a respiratory physiotherapeutic program in liver transplantation candidates.

BACKGROUND: Candidates for liver transplantation may have malnutrition, fatigue, loss of muscle mass and function. The combination of these factors leads to overall physical disability and physical inactivity. OBJECTIVE: The aim of the study was to evaluate the effects of a respiratory physiotherapeutic program on liver transplantation candidates. METHOD: Forty-two patients were evaluated by respiratory muscle strength, surface electromyography of the rectus abdominis and diaphragm, and spirometry. We also applied the SF-36. The patients were divided into two groups: 12 randomly assigned to the control group and 5 in the intervention group. The intervention consisted of an explanatory and illustrative manual to be followed at home with diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT, lifting the upper limbs with a bat, and strengthening the abdominals. RESULTS: Significant difference was found between initial forced expiratory flow (FEF)25-75% (P = .042) and final FEF25-75 in the intervention group. The control group had significant difference (P = .036) in the diaphragm RMS between initial time and end time. In conclusion, the control group showed greater electrical activity of the diaphragm after 3 months. CONCLUSION: The intervention group benefited from the exercise, thus improving the FEF25-75%.

Nutrition support in end-stage liver disease.

Protein-calorie malnutrition is common in end-stage liver disease, irrespective of cause, and adversely affects clinical outcomes. Early diagnosis is important to allow appropriate intervention to prevent malnutrition-associated complications. Correction of nutrient deficiencies through oral supplementation, enteral tube feeding, or parenteral feeding can improve clinical outcomes in this patient population. This article addresses the causes of malnutrition, methods used to assess nutritional status, and treatment strategies in end-stage liver disease.
