RESUMO

The benefits of branched-chain amino acid (BCAA) administration after hepatic intervention in patients with liver diseases remain unclear. We conducted a systematic review and meta-analysis to evaluate the effects of BCAA on patients undergoing hepatectomy, trans-arterial embolisation and radiofrequency ablation. Relevant randomised controlled trials (RCT) were obtained from PubMed, EMBASE and Cochrane Library databases. A meta-analysis was performed to calculate the pooled effect size by using random-effects models. The primary outcomes were survival and tumour recurrence. The secondary outcomes were hospital stay, nutrition status, biochemistry profile, complication rate of liver treatment and adverse effect of BCAA supplementation. In total, eleven RCT involving 750 patients were included. Our meta-analysis showed no significant difference in the rates of tumour recurrence and overall survival between the BCAA and control groups. However, the pooled estimate showed that BCAA supplementation in patients undergoing hepatic intervention significantly increased serum albumin (mean difference (MD): 0·11 g/dl, 95 % CI: 0·02, 0·20; 5 RCT) at 6 months and cholinesterase level (MD: 50·00 U/L, 95 % CI: 21·08, 78·92; 1 RCT) at 12 months and reduced ascites incidence (risk ratio: 0·39, 95 % CI: 0·21, 0·71; 4 RCT) at 12 months compared with the control group. Additionally, BCAA administration significantly increased body weight at 6 months and 12 months and increased arm circumference at 12 months. In conclusion, BCAA supplementation significantly improved the liver function, reduced the incidence of ascites and increased body weight and arm circumference. Thus, BCAA supplementation may beneficial for selected patients undergoing liver intervention.

RESUMO

INTRODUCTION: Oxaliplatin is a third-generation platinum-based antineoplastic drug that is widely used to treat patients with colorectal cancer. Reported adverse reactions include hepatic sinusoidal obstruction syndrome and liver fibrosis, but there are few reports of cirrhosis associated with chemotherapy. In addition, the pathogenesis of cirrhosis remains unclear. CASE REPORT: We report a case of suspected oxaliplatin-induced liver cirrhosis, an adverse reaction that has not been previously reported. MANAGEMENT AND OUTCOME: A 50-year-old Chinese man was diagnosed with rectal cancer and underwent laparoscopic radical rectal cancer surgery. The patient had a history of schistosomiasis, but history and serology showed no evidence of chronic liver disease. However, after five oxaliplatin-based chemotherapy cycles, the patient presented dramatic changes in liver morphology and developed splenomegaly, massive ascites, and elevated CA125 levels. Four months after discontinuing oxaliplatin, the patient's ascites had decreased significantly and CA125 levels declined from 505.3 to 124.6 mU/mL. After 15 weeks of follow-up, CA125 levels decreased to the normal range, and there has been no increase in ascites in this patient. DISCUSSION: Oxaliplatin-induced cirrhosis may be a serious complication and should be discontinued based on clinical evidence.

RESUMO

Background and Objectives: To find low-cost markers that can identify the hepatitis C virus cirrhotic patients that are at risk for long-term severe adverse liver effects (ascites, ascites or upper gastrointestinal bleeding, hepatocellular carcinoma), after treatment. There is established evidence for the benefits of treating hepatitis C virus cirrhotic patients, but there is still some need for clarification concerning the real impact on the long-term evolution after achieving sustained virological response; there is no general consensus in the literature about identifying the patients that do not improve post-treatment. Materials and Methods: Our retrospective analysis investigated the long-term (2 years) evolution of 46 patients with cirrhosis with thrombocytopenia, previously infected with VHC, treated and who obtained an SVR after DAA treatment. Results: Despite the overall improvement, 8.7% patients developed hepatocellular carcinoma and 6.5% patients ascites/upper GI bleeding. We found that FIB-4, MELD and AFP changes at 1 year were the most significant predictors for these outcomes. Additionally, a drop in leukocyte count after 1 year seemed to indicate a risk for hepatocellular carcinoma, but this was not consistent. Conclusions: It might be beneficial to intensify the surveillance for post-treatment adverse liver effects for the patients with these marker changes at 1 year.

RESUMO

Common side effects of mycophenolate mofetil (MMF) are diarrhea, leukopenia, and infectious complication. The polymorphisms of enzymes affecting MMF clearance could be related to MMF toxicity, and in vitro study revealed that high MMF levels might cause endothelial dysfunction. A 7-year-old Korean male with end-stage renal disease on peritoneal dialysis due to mesangial proliferative glomerulonephritis received a kidney transplantation (KT) from a deceased donor, and immunosuppressive medications including MMF, tacrolimus, and methylprednisolone were started after KT. The patient developed oliguria immediately after surgery, and therapeutic plasmapheresis was initiated with continuous renal replacement therapy for the possibility of graft dysfunction and nephrotic syndrome relapse. Renal function recovered 4 days later, but the patient developed ascites. Diagnostic paracentesis revealed findings that were interpreted as uncomplicated ascites in cirrhosis, not of renal origin. Abdominal ultrasonography showed increased parenchymal echogenicity without cirrhotic change in the liver. Based on a case report and differential diagnosis, we replaced MMF with azathioprine, and 4 weeks later a sudden increment in urine output was detected. Eleven months after KT, the patient is free from ascites. The UGT2B7 802 polymorphism was tested, and wild-type UGT2B7 802 was detected, which is related to low MMF clearance. The low clearance of MMF by UGT2B7 802 wild-type polymorphism might have led to MMF toxicity affecting endothelial dysfunction. This case suggests that refractory ascites could be induced by MMF, and endothelial damage is a possible mechanism.

RESUMO

Ascites syndrome (AS) is a harmful disease in fast-growing broilers characterized by heart failure and serious fluid accumulation in the abdominal cavity. One of the known functions of zinc transporter ZIP12 is an important regulator in pulmonary hypertension (PH) in rat. Whether chicken ZIP12 is involved in the process of AS need to be explored. Here, chicken ZIP12 was sequenced and expression pattern and histological distribution were detected in broilers of AS induced by intravenous cellulose microparticle injection. Phylogenetic analysis showed that ZIP12 was significantly different between chicken and mammalian. The relative mRNA expression level of ZIP12 in the liver and lung in AS and pre-ascites (PAS) groups were significantly higher (P < 0.01) than that in control. The immunohistological staining using rabbit anti-chicken ZIP12 IgG and integrated optical density analysis showed the positive cells of ZIP12 distributed in detected tissues and the expression level of ZIP12 protein increased in AS and PAS groups compared to control. The results will provide the basic data of ZIP12 in the pathological process of AS in broiler chickens and offer an important reference for prevention and control of the disease.

RESUMO

Water accumulation in the interstitium (edema) and the peritoneum (ascites) of nephrotic patients is classically thought to stem from the prevailing low plasma albumin concentration and the decreased transcapillary oncotic pressure gradient. However, several clinical and experimental observations suggest that it might also stem from changes in capillary permeability. We addressed this hypothesis by studying the peritoneum permeability of rats with puromycin aminonucleoside-induced nephrotic syndrome. The peritoneum of puromycin aminonucleoside rats displayed an increase in the water filtration coefficient of paracellular and transcellular pathways, and a decrease in the reflection coefficient to proteins. It also displayed oxidative stress and subsequent activation of NF-κB. Scavenging of reactive oxygen species and inhibition of NF-κB prevented the changes in the water permeability and reflection coefficient to proteins and reduced the volume of ascites by over 50%. Changes in water permeability were associated with the overexpression of the water channel aquaporin 1, which was prevented by reactive oxygen species scavenging and inhibition of NF-κB. In conclusion, nephrotic syndrome is associated with an increased filtration coefficient of the peritoneum and a decreased reflection coefficient to proteins. These changes, which account for over half of ascite volume, are triggered by oxidative stress and subsequent activation of NF-κB.

RESUMO

Although autologous stem cell transplantation can achieve excellent responses in patients with POEMS syndrome, the optimal regimen for peripheral blood stem cell (PBSC) collection is still controversial. We retrospectively investigated the safety and efficacy of 41 PBSC collecting procedures in 37 patients with POEMS syndrome. PBSC mobilization was performed using cyclophosphamide + granulocyte colony-stimulating factor (G-CSF) (CG, n = 14) or G-CSF alone (G, n = 27). Twelve (85.7%) patients in the CG group and all (100%) patients in the G group received induction chemotherapy before PBSC collection. The proportions of good mobilizers (≥2.0 × 106 CD34+ cells/kg) were comparable between the 2 groups (CG versus G: 78.6% versus 70.4%, P = .71). Two (14.3%) patients in the CG group developed severe capillary leak symptoms during the PBSC mobilization period, whereas no patient in the G group experienced severe adverse events. Appropriate induction therapies followed by the G-CSF monotherapy compose an optimal strategy for PBSC collection.

RESUMO

Veno-occlusive disease (VOD), or sinusoidal obstruction syndrome, is a well-recognised, serious complication associated with the chemotherapy conditioning therapy used in hematopoietic stem cell transplantation (HSCT). Fluid management is typically challenging in children with this condition. We describe effective early use of peritoneal dialysis catheters to drain extravascular, intra-abdominal fluid in children with VOD, allowing intravascular fluid administration to preserve renal perfusion and function, preventing multi-organ dysfunction. All but one of the children are long-term survivors, both of their significant VOD and their HSCT. The child that did not survive died from their underlying metabolic illness, not VOD.

RESUMO

BACKGROUND: Mycophenolic acid (MPA), either given as an ester pro-drug or as an enteric-coated sodium salt, is the most commonly prescribed anti-proliferative immunosuppressive agent used following organ transplantation and widely applied in immune-mediated diseases. Clinicians are well aware of common adverse reactions related to MPA treatment, in particular diarrhea, leukopenia and infections. Here we report a case of severe, persistent ascites associated with MPA treatment. The otherwise unexplained and intractable ascites, requiring repeated paracenteses for more than 8 months, rapidly ceased with stopping the MPA treatment. To our knowledge this is the first case of severe ascites associated with MPA treatment reported in the scientific literature. CASE PRESENTATION: A 45-year old female with type 1 diabetes mellitus received a simultaneous kidney-pancreas transplant. The surgery was uneventful. However, post-operatively she developed severe transudative ascites requiring in total more than 40 paracenteses treatments draining in the average 2.8 l of ascites fluid. The ascites formation persisted despite exclusion of a surgical complication, fully functioning kidney and pancreas allografts, lack of any significant proteinuria, normalization of circulating albumin levels, intensive use of diuretics and deliberate attempts to increase the intervals between the paracentesis treatments. Various differential diagnoses, including infectious, hepatic, vascular and cardiac causes were ruled out. Nine months after surgery enteric-coated mycophenolate sodium was switched to azathioprine after which ascites completely resolved. When mycophenolate was recommenced abdominal fullness and weight gain reoccurred. The patient had to be switched to long-term azathioprine treatment. More than 1 year post-conversion the patient remains free of ascites. CONCLUSION: MPA is the most widely used antimetabolite immunosuppressive agent. We suggest to consider MPA treatment in the differential diagnosis of severe and unexplained ascites in transplant and non-transplant patients.

RESUMO

BACKGROUND: Angioedema is an infrequent complication of the use of angiotensin-converting enzyme inhibitors (ACEi) that has an incidence of up to 0.5%. The oropharynx is most commonly affected. Angioedema of the small bowel is a much rarer occurrence; it uniformly presents with abdominal pain of variable duration. CASE REPORT: A 51-year-old man presented to the emergency department (ED) with generalized abdominal pain, emesis, diarrhea, and bloating. Medical history was significant for hypertension and medications included captopril, metoprolol and aspirin. Vital signs and laboratory tests were unremarkable. Due to the presence of significant abdominal tenderness with guarding on examination, a FAST (focused assessment with ultrasound in trauma) examination was performed and revealed free fluid in the abdomen. A computed tomography scan of the abdomen was quickly obtained, which revealed a large amount of simple-appearing free fluid within the abdomen and mucosal edema throughout the small bowel. The patient underwent an emergent diagnostic laparoscopy and was ultimately diagnosed with angioedema of the small bowel, deemed secondary to captopril usage. Captopril was discontinued and symptoms gradually resolved with supportive care. When imaging is obtained in cases such as this one, small bowel submucosal edema and ascites are often present. Supportive care and cessation of ACEi usage are the cornerstones of treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In patients on ACEi, it is important to keep this diagnosis in mind to potentially avoid an unneeded surgical intervention, as the condition is self-limiting and can be treated primarily with supportive measures.

RESUMO

Occupational and environmental exposure to potassium dichromate (K2Cr2O7), a hexavalent chromium compound, can result in liver damage associated with oxidative stress and mitochondrial dysfunction. The purpose of this study was to evaluate the effect of the antioxidant curcumin (400 mg/kg b.w.) on the K2Cr2O7-induced injury, with special emphasis on ascitic fluid accumulation and oxidative phosphorylation mitochondrial enzymes and the adenosine triphosphate (ATP) levels in isolated mitochondria from livers of rats treated with K2Cr2O7 (15 mg/kg b.w.). Thus, curcumin attenuated the ascites generation, prevented the decrease in the activities of aconitase and F1F0 ATPase, and maintained the ATP levels. The activity of complex II was not completely reestablished by curcumin, whereas complexes III and IV activities were unchanged.

RESUMO

This report describes a 6-year-old boy with disseminated low-grade astrocytoma and ventriculo-peritoneal shunt, who developed recurrent ascites while receiving sorafenib on a clinical trial. Laboratory analysis of the peritoneal fluid showed no elevation of protein content and no evidence of underlying infection or tumor dissemination. This report highlights ascites as a previously unrecognized adverse reaction to sorafenib in a patient with a ventriculo-peritoneal shunt. We conclude that such patients should be closely monitored for this complication when treated with sorafenib.

RESUMO

AIM: To evaluate the technical feasibility of artificial ascites formation using an angiosheath before percutaneous radiofrequency ablation (RFA) for hepatic tumours and to determine predictive factors affecting the technical failure of artificial ascites formation. MATERIALS AND METHODS: This retrospective study was approved by the institutional review board. One hundred and thirteen patients underwent percutaneous RFA of hepatic tumours after trying to make artificial ascites using an angiosheath to avoid collateral thermal damage. The technical success rate of making artificial ascites using an angiosheath and conversion rate to other techniques after initial failure of making artificial ascites were evaluated. The technical success rate for RFA was assessed. In addition, potential factors associated with technical failure including previous history of transcatheter arterial chemoembolization (TACE) or RFA, type of abdominal surgery, and adjacent perihepatic structures were reviewed. Predictive factors for the technical failure of artificial ascites formation were analysed using multivariate analysis. RESULTS: The technical success rates of artificial ascites formation by angiosheath and that of RFA were 84.1% (95/113) and 97.3% (110/113), respectively. The conversion rate to other techniques after the failure of artificial ascites formation using an angiosheath was 15.9% (18/113). Previous hepatic resection was the sole independent predictive factor affecting the technical failure of artificial ascites formation (p<0.001, odds ratio = 29.03, 95% confidence interval: 4.56-184.69). CONCLUSION: Making artificial ascites for RFA of hepatic tumours using an angiosheath was technically feasible in most cases. However, history of hepatic resection was a significant predictive factor affecting the technical failure of artificial ascites formation.

RESUMO

BACKGROUND: Terlipressin has been widely used for various cirrhosis-related complications, but its safety profile remains controversial. Herein, this issue was systematically evaluated. METHODS: All studies reporting adverse events (AEs) of terlipressin in cirrhosis were screened. Incidences were pooled using a random-effects model. Subgroup analyses were performed according to the patient's characteristics and treatment regimens. Interaction among subgroups was evaluated. RESULTS: Seventy-eight studies with 7257 patients with cirrhosis were included. The pooled incidences of any AEs, treatment-related AEs, any serious AEs (SAEs), treatment-related SAEs, treatment withdrawal due to AEs, and treatment withdrawal due to treatment-related AEs were 31%, 22%, 5%, 5%, 4%, and 4% in patients with cirrhosis receiving terlipressin, respectively. Patients with hepatorenal syndrome had higher incidences of any SAEs (29% vs. 0% vs. 0%, pinteraction = 0.01) and treatment-related SAEs (8% vs. 1% vs. 7%, pinteraction = 0.02) than those with variceal bleeding or ascites. Patients who received terlipressin with human albumin had higher incidences of any SAEs (18% vs. 1%, pinteraction = 0.04) and treatment-related SAEs (7% vs. 0%, pinteraction = 0.09) than those without albumin. Patients with total bilirubin level >4.3 mg/dL had higher incidences of any AEs (69% vs. 24%, pinteraction = 0.02), any SAEs (64% vs. 0%, pinteraction < 0.01), and treatment-related SAEs (8% vs. 1%, pinteraction = 0.04) than those ≤4.3 mg/dL. CONCLUSIONS: AEs are common in patients with cirrhosis receiving terlipressin and influenced by clinical scenarios, combination with albumin, and bilirubin levels.

RESUMO

UNLABELLED: Cirrhosis with ascites is associated with a high rate of gut bacterial translocation (GBT) and spontaneous bacterial infections of enteric origin. We addressed the activation state and role of intestinal dendritic cells (DCs) in experimental ascitic cirrhosis and their relationship with GBT. Cirrhosis with ascites was CCl(4) induced in rats. To examine their activation state and functions, DCs (CD103(+) RT1B(+) CD3(-) CD45RA(-) ) were isolated from the intestinal lamina propria and mesenteric lymph nodes (MLNs), and the following parameters were determined by flow cytometry: surface antigen expression; spontaneous or lipopolysaccharide-stimulated tumor necrosis factor alpha (TNF-α) production; and in vitro capacity to phagocytose latex beads and to migrate toward the chemokine (C-C motif) ligand 21. GBT was defined as the growth of bacteria in MLNs culture. Bacterial DNA (Bact-DNA) in MLNs was identified by polymerase chain reaction. In rats with Bact-DNA in MLNs without GBT, intestinal and MLNs CD103(+) -DCs showed features of activation, expansion of the proinflammatory CD4(+) -DC subpopulation, augmented TNF-α production, and increased phagocytic and migratory capacities. In contrast, in rats with GBT, CD103(+) -DCs showed the absence of an activated phenotype, lowered TNF-α production, and relatively deficient phagocytosis and migration capacities. The CD103(+) -DC of rats without Bact-DNA in MLNs or GBT were similar to controls. In cirrhotic rats, bowel decontamination with antibiotics eliminated Bact-DNA in MLNs and GBT, normalized the activation state and functions of CD103(+) -DCs, and increased their TNF-α production. CONCLUSION: In experimental cirrhosis with ascites, continuous pressure of gut bacteria shapes the phenotypic and functional profile of intestinal DCs to produce effects that range from their activation and enhanced functions to their exhaustion and tolerance.

BACKGROUND AND AIM: Worldwide anti-tuberculosis (TB) drug-induced liver disease (DILI) is an important cause of hepatotoxicity, and drug-induced acute liver failure (ALF). Reported series on anti-TB DILI are limited by a mix of cases with mild transaminase elevation or adaptation. Our aim was to analyze the clinical features, laboratory characteristics, outcome, and determine predictors of 90-day mortality. METHODS: Single center analysis of consecutive cases of anti-TB DILI following combination anti-TB drugs exposure from 1997-2011. RESULTS: Of the 269 patients, 191 (71%) experienced jaundice and 69 (25.7%) accounted for ALF. The mean age and treatment duration was 41.3 years and 1.9 months, respectively; males constituted 55.7%. DILI occurred throughout the course of treatment; three-quarters occurred within the first 2 months. HIV infection was present in 21 (7.8%). The 90-day mortality was 22.7%. DILI accompanied by jaundice (n = 191), encephalopathy (n = 69) or ascites (n = 69) resulted in mortality in 30%, 69.6% and 50.7%, respectively (P < 0.001). Age, gender, transaminase levels, HIV or hepatitis B surface antigen (HBsAg) status did not influence survival. Treatment duration, encephalopathy, ascites, bilirubin, serum albumin, international normalized ratio (INR), serum creatinine and leukocyte count were associated with mortality (P < 0.001). Multivariate logistic regression model for mortality, incorporating encephalopathy, albumin, bilirubin, INR, and creatinine yielded a C-statistic of 97%. CONCLUSIONS: Anti-TB DILI occurs throughout treatment duration progressing to ALF in a quarter of patients. The overall mortality is 22.7%, which is higher when accompanied by jaundice, ascites or encephalopathy. An anti-TB DILI model, incorporating bilirubin, INR, encephalopathy, serum creatinine and albumin predicted mortality with C-statistic of 97%.

RESUMO

Hypoxia-inducible factor 1 (HIF-1) is a ubiquitously expressed heterodimeric transcription factor that mediates adaptive responses to hypoxia in all nucleated cells of metazoan organisms. Hypoxia-inducible factor 1α is involved in the pathogenesis of pulmonary hypertension in humans and animals, but whether HIF-1α is associated with the development of pulmonary hypertension syndrome (also known as ascites syndrome, AS) in broiler chickens has not been determined. In the present paper we addressed this issue by measuring the expression of HIF-1α mRNA in hearts and lungs of broiler chickens with AS induced by excess salt in drinking water. We conducted 2 experiments. The first experiment was used to observe the effects of excess salt on AS incidence. The results indicated that total incidence (20%) of AS in excess salt group (receiving 0.3% NaCl in drinking water) was much higher compared with the control group (receiving tap water) over a 43-d time course (P < 0.05). In the second experiment, we determined mean pulmonary arterial pressure (mPAP), ascites heart index (AHI), and expression of HIF-1α mRNA in lungs and hearts of broiler chickens after the excess salt treatment. Our results showed that excess salt induced pulmonary hypertension (indicated by higher mPAP) and right ventricular hypertrophy (greater ascites heart index) in broiler chickens. Meanwhile, the expression levels of HIF-1α mRNA in lungs and hearts were significantly increased at different time points in the excess salt group compared with the control group. Linear correlation analysis showed that the expression of HIF-1α mRNA in lungs was significantly positively correlated with mPAP (correlation coefficient = 0.79, P < 0.001), demonstrating that expression of HIF-1α mRNA was gradually increased in the excess salt group with the increase of pulmonary arterial pressure. In addition, the ascitic chickens showed significantly higher transcriptional levels of HIF-1α in hearts and lungs, compared with the age-matched healthy chickens, respectively. Our findings hinted that HIF-1α might be associated with the development of AS induced by excess salt in drinking water in broiler chickens.

RESUMO

CONTEXT: Trichosanthes dioica Roxb. (Cucurbitaceae), called pointed gourd in English, is a dioecious climber found wild throughout the plains of the Indian subcontinent and traditionally used in India for several medicinal purposes. OBJECTIVE: The present study evaluated the protective effect of the triterpenoid enriched fraction from T. dioica root (CETD) against experimentally induced acute inflammatory ascites in Wistar albino rats. MATERIALS AND METHODS: The CETD was administered orally at the different doses (25, 50 and 100 mg/kg body weight) to overnight fasted rats, and then ascites was induced by intraperitoneal administration of formalin solution. After 7 h, the rats were sacrificed and the volume of ascitic fluid was measured. RESULTS: The CETD demonstrated significant (p < 0.01) reduction of ascitic fluid formation in a dose-dependent manner as compared with control. CONCLUSION: The CETD produced significant and dose-dependent inhibition of experimentally induced inflammatory ascites in Wistar albino rats.
