RESUMEN
BACKGROUND: Human immunodeficiency virus (HIV)-positive patients coinfected with hepatitis B virus (HBV) are eligible for liver transplantation (LT) in Africa and Southeast Asia, particularly China. However, the outcome of HIV-HBV coinfected patients referred for ABO-incompatible LT (ABOi-LT) is unknown. AIM: To clarify the outcome of ABOi-LT for HIV-HBV coinfected patients with end-stage liver disease (ESLD). METHODS: We report on two Chinese HIV-HBV coinfected patients with ESLD who underwent A to O brain-dead donor LT and reviewed the literature on HIV-HBV coinfected patients treated with ABO-compatible LT. The pretransplantation HIV viral load was undetectable, with no active opportunistic infections. Induction therapy consisted of two sessions of plasmapheresis and a single dose of rituximab in two split doses, followed by an intraoperative regimen of intravenous immunoglobulin, methylprednisolone, and basiliximab. Post-transplant maintenance immunosuppressive agents consisted of tacrolimus and mycophenolate mofetil, and prednisone. RESULTS: At the intermediate-term follow-up, patients showed undetectable HIV viral load, CD4(+) T cell counts greater than 150 cells/µL, no HBV recurrence, and stable liver function. A liver allograft biopsy showed no evidence of acute cellular rejection. Both patients survived at 36-42 mo of follow-up. CONCLUSION: This is the first report of ABOi-LT in HIV-HBV recipients with good intermediate-term outcomes, suggesting that ABOi-LT may be feasible and safe for HIV-HBV coinfected patients with ESLD.

AIM: To compare the clinical outcomes of right hepatectomy for large hepatocellular carcinoma via the anterior and conventional approach. METHODS: We comprehensively performed an electronic search of PubMed, EMBASE, and the Cochrane Library for randomized controlled trials (RCTs) or controlled clinical trials (CCTs) published between January 2000 and May 2017 concerning the anterior approach (AA) and the conventional approach (CA) to right hepatectomy. Studies that met the inclusion criteria were included, and their outcome analyses were further assessed using a fixed or random effects model. RESULTS: This analysis included 2297 patients enrolled in 16 studies (3 RCTs and 13 CTTs). Intraoperative blood loss [weighted mean difference = -255.21; 95% confidence interval (95%CI): -371.3 to -139.12; P < 0.0001], intraoperative blood transfusion [odds ratio (OR) = 0.42; 95%CI: 0.29-0.61; P < 0.0001], mortality (OR = 0.59; 95%CI: 0.38-0.92; P = 0.02), morbidity (OR = 0.77; 95%CI: 0.62-0.95; P = 0.01), and recurrence rate (OR = 0.62; 95%CI: 0.47-0.83; P = 0.001) were significantly reduced in the AA group. Patients in the AA group had better overall survival (hazard ratio [HR] = 0.71; 95%CI: 0.50-1.00; P = 0.05) and disease-free survival (HR = 0.67; 95%CI: 0.58-0.79; P < 0.0001) than those in the CA group. CONCLUSION: The AA is safe and effective for right hepatectomy for large hepatocellular carcinoma and could accelerate postoperative recovery and achieve better survival outcomes than the CA.

Premotor Parkinson's disease (PD) refers to a prodromal stage of Parkinson's disease (PD) during which nonmotor clinical features may be present. Currently, it is difficult to make an early diagnosis for premotor PD. Molecular imaging with position emission tomography (PET) or single-photon emission tomography (SPECT) offers a wide variety of tools for overcoming this difficulty. Indeed, molecular imaging techniques may play a crucial role in diagnosing, monitoring and evaluating the individuals with the risk for PD. For example, dopaminergic dysfunctions can be identified by detecting the expression of vesicular monoamine transporter (VMAT2) and aromatic amino acid decarboxylase (AADC) to evaluate the conditions of dopaminergic terminals functions in high-risk individuals of PD. This detection provides a sensitive and specific measurement of nonmotor symptoms (NMS) such as olfactory dysfunction, sleep disorders, and psychiatric symptoms in the high-risk patients, especially at the premotor phase. Molecular imaging technique is capable of detecting the dysfunction of serotonergic, noradrenergic, and cholinergic systems that are typically associated with premotor manifestations. This review discusses the importance of SPECT/PET applications in the detection of premotor markers preceding motor abnormalities with highlighting their great potential for early and accurate diagnosis of premotor symptoms of PD and its scientific significance.
