Ehrlich ascites carcinoma provokes renal toxicity and DNA injury in mice: Therapeutic impact of chitosan and maitake nanoparticles.

In this study, the impact of chitosan (CS) and maitake (GF) nanoparticles towards the renal toxicity induced by Ehrlich ascites carcinoma (EAC) in vivo model was conducted. Besides benchmark negative control group, EAC model was constructed by intraperitoneal injection (i.p.) of 2.5 × 106 cells. Alongside positive control, two groups of EAC-bearing mice received 100 mg/kg of CS and GF nanoparticles/body weight daily for 14 days. The kidney function was conducted by measuring urea, creatinine, ions, (anti)/oxidative parameters and DNA damage. Also, measuring immunoreactivity of P53, proliferating cell nuclear antigen (PCNA), and B-cell lymphoma 2 (Bcl-2) and apoptosis protein. The outcomes illustrated notable kidney toxicity, which indicated by elevations in urea, creatinine, oxidative stress, DNA damage and induction of apoptosis. These events were supported by the drastic alteration in kidney structure through histological examination. Administration of CS and GF nanoparticles was able to enhance the antioxidant power, which further reduced oxidative damage, DNA injury, and apoptosis. These results indicated the protective and therapeutic role of biogenic chitosan and maitake nanoparticles against nephrotoxicity.

Gansui Banxia decoction modulates immune-inflammatory homeostasis to ameliorate malignant ascites in rats.

BACKGROUND: "Gansui Banxia decoction" (GBD) is a classical traditional Chinese medicine formula for treating abnormal accumulation of fluid, such as malignant ascites (MA). Although GBD has shown definite water-expelling effects, its exact underlying mechanism has not been elucidated. PURPOSE: This study aimed to investigate the drug effects of GBD on MA rats and its underlying mechanisms. METHODS: The main chemical composition was determined by ultra-high performance liquid chromatography. The drug effects of GBD was evaluated in the established cancer cell-induced MA rat model. The symptoms were analyzed, and biological samples were collected for detecting immune and inflammation-related indicators by enzyme-linked immunosorbent assays, western blot, and flow cytometry. RESULTS: GBD increased urine discharge, decreased ascites production, and alleviated cachexia. After GBD treatment, the expression of TLR4, MyD88, and NF-кB and the release of pro-inflammatory cytokines such as interleukin (IL)-1ß, IL-6, and tumor necrosis factor (TNF)-α were reduced. In addition, GBD increased G1 phase arrest and inhibit excessive proliferation of cells in bone marrow while alleviating G1 phase arrest and increasing proliferation of cells in the thymus. Correspondingly, the development and maturation of T cells also changed. GBD increased the proportion of mature T-cells (CD4+CD8- and CD4-CD8+ single-positive (SP) T-cells), and decrease the proportion of immature cells (CD4+CD8+ double-positive (DP) T-cells and CD4-CD8- double-negative (DN) T-cells) in the blood or tumor microenvironment (TME, the ascites microenvironment). Finally, we further analysis of immune cell subsets, GBD decreased the proportion of immunosuppressive T-cells in the blood (CD4+CD25+Foxp3+T-cells) and TME (CD8+CD25+Foxp3+T-cells), and increased the proportion of anti-tumor immune cells (CD8+CD28+T-cells and NK cells) in the TME. CONCLUSION: These findings indicated that the drug effects of GBD were attributed to regulating the immune-inflammatory homeostasis, thereby mitigating the destruction of cancer cells and reducing the generation of ascites, which provided theoretical support for the clinical rational application and extended the scientific connotation of "water-expelling" of GBD.

Advances in the treatment of malignant ascites in China.

PURPOSE: Malignant ascites (MA) often occurs in recurrent abdominal malignant tumors, and the large amount of ascites associated with cancerous peritonitis not only leads to severe abdominal distension and breathing difficulties, but also reduces the patient's quality of life and ability to resist diseases, which usually makes it difficult to carry out anti-cancer treatment. The exploration of MA treatment methods is also a key link in MA treatment. This article is going to review the treatment of MA, to provide details for further research on the treatment of MA, and to provide some guidance for the clinical treatment of MA. METHOD: This review analyzes various expert papers and summarizes them to obtain the paper. RESULT: There are various treatment methods for MA, including systemic therapy and local therapy. Among them, systemic therapy includes diuretic therapy, chemotherapy, immunotherapy, targeted therapy, anti angiogenic therapy, CAR-T, and vaccine. Local therapy includes puncture surgery, peritoneal vein shunt surgery, acellular ascites infusion therapy, radioactive nuclide intraperitoneal injection therapy, tunnel catheter, and intraperitoneal hyperthermia chemotherapy. And traditional Chinese medicine treatment has also played a role in enhancing efficacy and reducing toxicity to a certain extent. CONCLUSION: Although there has been significant progress in the treatment of MA, it is still one of the clinical difficulties. Exploring the combination or method of drugs with the best therapeutic effect and the least adverse reactions to control MA is still an urgent problem to be solved.

The effect of peroxisome proliferator-activated receptor gamma (PPARγ) as a mediator of dietary fatty acids and thiazolidinedione in pulmonary arterial hypertension induced by cold stress of broilers.

The objective of this experiment was to evaluate the effects of dietary fish oil and pioglitazone as peroxisome proliferators-activated receptor gamma (PPARγ) activating ligands on the reduction of cold-induced ascites in broiler chickens. A total of 480 one-day-old (Ross 308) male chicks were randomly allocated to four treatment groups with eight replicates of 15 birds each. The following treatments were used: 1) ambient temperature (negative control), with basal diet; 2) cold-induced ascites (positive control), with basal diet; 3) cold-induced ascites, with basal diet +10 mg/kg/day pioglitazone and 4) cold-induced ascites, with basal diet +1% of fish oil. When compared with the positive control, body weight gain was higher (P ≤ 0.05) for broilers fed diets containing fish oil and pioglitazone at 28, 42, and 0-42 d. Broilers under cold-induced ascites had the highest blood pressure at 21 and 42 d, while fish oil and pioglitazone treatment reduced the blood pressure (P ≤ 0.05). Red blood cells, white blood cells, hematocrit, erythrocyte osmotic fragility, bursa of Fabricius and spleen weights were improved (P ≤ 0.05) for chickens fed fish oil diets and pioglitazone compared to the cold-induced ascites (positive control). Exposure to cold temperature resulted in an increase in plasma T3 and T3/T4 ratio and decline in plasma T4 (P ≤ 0.05). In conclusion, PPARγ agonist pioglitazone and fish oil as source of omega-3 polyunsaturated fatty acid could be used as a strategy to reduce the negative effects of pulmonary arterial hypertension and ascites in broiler chickens.

An Emulated Clinical Trial of Deprescribing Proton Pump Inhibitors in Patients With Cirrhosis.

INTRODUCTION: Proton pump inhibitors (PPI) are overused and carry harms in cirrhosis. Deprescribing is advocated but has not been trialed. METHODS AND FINDINGS: We emulated a clinical trial using Medicare data. All patients were receiving chronic PPI therapy before a compensated cirrhosis diagnosis. We compared the risk death/decompensation over 3 years between continuous users and deprescribers. We find that PPI deprescription is associated with less ascites and that cumulative PPI use is associated with more ascites and encephalopathy. Ultimately, 71% of deprescribers restart PPIs. DISCUSSION: PPI deprescribing has benefits but requires ongoing support and alternative therapies for gastrointestinal symptoms.

Effects of branched-chain amino acids supplementation on patients undergoing hepatic intervention: a meta-analysis of randomised controlled trials.

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.

A case of pseudomyxoma peritonei arising from a perforated intraductal papillary mucinous neoplasm that underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Pseudomyxoma peritonei (PMP) of pancreatic origin arising from an intraductal papillary mucinous neoplasm (IPMN) is rare. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has been established as the optimal treatment for PMP. However, the benefits and safety of CRS with HIPEC for treating PMP of pancreatic origin remain unclear. Herein, we describe a case of PMP of pancreatic origin that was treated with CRS and HIPEC without postoperative complications. A 75-year-old woman was referred to our department. Computed tomography (CT) revealed a multilocular cystic tumor in the pancreatic tail, notable mucinous ascites in the abdominal cavity, and scalloping of the liver and spleen. CT did not reveal the appendix, and the ovaries were normal in size. The patient was diagnosed with PMP of pancreatic origin, and CRS and HIPEC were performed. Intraoperatively, the pancreatic tumor was perforated, and there was a large amount of mucinous ascites. We performed distal pancreatectomy in addition to CRS and HIPEC, with no intraoperative complications. The postoperative course was uneventful, and the patient survived after 6 months without recurrence. CRS with HIPEC may be a feasible treatment option for PMP of pancreatic origin.

Progress in the treatment of malignant ascites.

Malignant ascites occurs as a symptom of the terminal stage of cancer, affecting the quality of life through abdominal distension, pain, nausea, anorexia, dyspnea and other symptoms. We describe the current main drug treatments in addition to surgery according to the traditional and new strategies. Traditional treatments were based on anti-tumor chemotherapy and traditional Chinese medicine treatments, as well as diuretics to relieve the patient's symptoms. New treatments mainly involve photothermal therapy, intestinal therapy and targeted immunity. This study emphasizes that both traditional and new therapies have certain advantages and disadvantages, and medication should be adjusted according to different periods of use and different patients. In conclusion, this article reviews the literature to systematically describe the primary treatment modalities for malignant ascites.

Evaluation of antioxidant, anti-inflammatory, anticancer activities and molecular docking of Moringa oleifera seed oil extract against experimental model of Ehrlich ascites carcinoma in Swiss female albino mice.

The current research intended to evaluate the antitumor properties of Moringa oleifera oil extract (MOE). Fifty-six female Swiss albino mice were employed in this study. Animals were assigned into four groups: control (C) group, moringa oil extract (MOE) group administered (500 mg/kg b. wt) MOE daily via gavage, Ehrlich ascites carcinoma (EAC) group and EAC group administered daily with (500 mg/kg b.wt) MOE for two weeks (EAC/MOE). The results showed that MOE significantly ameliorated the EAC increase in body weight and reduced the EAC cell viability. In addition, they upgraded the levels of hepatic and renal functions, inflammatory cytokines, oxidative stress markers and EAC-induced hepatic and renal histopathological changes. Treatment of EAC with MOE induced antitumor, anti-inflammatory and antioxidant effects and normalized most of the tested parameters besides the histopathological alterations in both renal and hepatic tissues. HPLC for the MOE identified Cinnamic acid, Ellagic acid, Quercetin, Gallic acid, Vanillin and Hesperidin as major compounds. The molecular docking study highlighted the virtual binding of the identified compounds inside the GSH and SOD proteins, especially for Quercetin which exhibited promising binding affinity with good interactive binding mode with the key amino acids. These results demonstrate that the antitumor constituents of MOE against EAC induced oxidative stress and inflammation by preventing oxidative damage and controlling EAC increase.

Use of metagenomic next-generation sequencing for diagnosis of peritonitis in end-stage liver disease.

Background: Conventional methods are low in positive rates and time-consuming for ascites pathogen detection in patients with end-stage liver disease (ESLD). With many advantages, metagenomic next-generation sequencing (mNGS) may be a good alternative method. However, the related studies are still lacking. Methods: Ascites from 50 ESLD patients were sampled for pathogen detection using mNGS and conventional methods (culture and polymorphonuclear neutrophils detection) in this prospective observational study. Results: Forty-two samples were detected positive using mNGS. 29 strains of bacteria, 11 strains of fungi, and 9 strains of viruses were detected. 46% of patients were detected to be co-infected with 2 or more pathogens by mNGS. Moreover, mNGS showed similar and high positive rates in ESLD patients with different clinical characteristics. Compared to conventional methods, mNGS had higher positivity rates (84% vs. 20%, P<0.001), sensitivity (45.2% vs. 23.8%, P=0.039), broader pathogen spectrum, shorter detection time (24 hours vs. 3-7 days), but lower specificity (25% vs 100%, P = 0.010). Furthermore, compared to conventional methods, mNGS showed similar consistence with final diagnosis (42% vs. 36%, P=0.539). Conclusions: mNGS may be a good supplement for conventional methods and helpful to early etiological diagnosis of peritonitis, and thus improve ESLD patients' survival.

Propolis-loaded nanostructured lipid carriers halt breast cancer progression through miRNA-223 related pathways: an in-vitro/in-vivo experiment.

The most frequent malignant tumor in women is breast cancer, and its incidence has been rising every year. Propolis has been used for its antibacterial, antifungal, and anti-inflammatory properties. The present study aimed to examine the effect of the Egyptian Propolis Extract (ProE) and its improved targeting using nanostructured lipid carriers (ProE-NLC) in Ehrlich Ascites Carcinoma (EAC) bearing mice, the common animal model for mammary tumors. EAC mice were treated either with 5-fluorouracil (5-FU), ProE, ProE-NLC, or a combination of ProE-NLC and 5-FU. Their effect on different inflammatory, angiogenic, proliferation and apoptotic markers, as well as miR-223, was examined. ProE and ProE-NLC have shown potential anti-breast cancer activity through multiple interrelated mechanisms including, the elevation of antioxidant levels, suppression of angiogenesis, inflammatory and mTOR pathways, and induction of the apoptotic pathway. All of which is a function of increased miRNA-223 expression. The efficiency of propolis was enhanced when loaded in nanostructured lipid carriers, increasing the effectiveness of the chemotherapeutic agent 5-FU. In conclusion, this study is the first to develop propolis-loaded NLC for breast cancer targeting and to recommend propolis as an antitumor agent against breast cancer or as an adjuvant treatment with chemotherapeutic agents to enhance their antitumor activity and decrease their side effects. Tumor targeting by ProE-NLC should be considered as a future therapeutic perspective in breast cancer.

Euphorbia factor L1 suppresses breast cancer liver metastasis via DDR1-mediated immune infiltration.

Euphorbia factor L1 (EFL1), a lathyrane-type diterpenoid from the medicinal herb Euphorbia lathyris L., has been documented to possess various pharmacologic actives. However, the function of EFL1 on breast cancer is not clear. In this study, we explored the effect and mechanism of EFL1 on breast cancer liver metastasis. Female BALB/c mice were subjected to breast cancer-surgical hepatic implantation (SHI) to establish breast cancer liver metastasis model in vivo. At 10 days post-surgery, mice were administrated with EFL1 once daily for a total of 2 weeks. Serum AST and ALT activities, abdominal circumference, peritoneal fluid, tumor weight and volume were determined to assess liver and mesenteric re-metastasis of breast cancer. H&E staining was used to observe morphology changes in tumor, liver and small intestine tissues. ELISA was applied to observe inflammatory levels. Tumor DDR1 expression and immune infiltration were determined using western blotting, immunohistochemistry and flow cytometer methods. Our results showed that EFL1 administration improved liver function (AST and ALT activities), ascites, liver metastasis and mesenteric re-metastasis in SHI mice. Also, SHI-induced inflammatory cell infiltration and IL-1ß, IL-6, TNF-α generation in ascites were decreased by EFL1 treatment. Mechanism study revealed that EFL1 intervention enhanced the ratios of CD4+ and CD8+ and CD49b+(NK) T lymphocytes and decreased Treg cells through downregulating DDR1 in the tumor of SHI mice. Furthermore, overexpression of DDR1 abolished the anti-liver metastasis effect and pro-immune infiltration action of EFL1 in SHI mice. Together, our findings suggested that EFL1 protects against breast cancer liver metastasis in vivo by targeting DDR1-mediated immune infiltration.

Surgical management of peritoneal metastasis: Opportunities for pharmaceutical research.

Cytoreductive surgery (CRS) has emerged as a survival-extending treatment of peritoneal metastasis (PM); recent advances include using intraperitoneal chemotherapy (IPC) at normothermic or hyperthermic temperatures, or under pressure (CRS + IPC). Clinical CRS + IPC research has established its highly variable efficacy and suggested tumor size, tumor locations and presence of ascites as potential determinants. On the other hand, there is limited knowledge on the effects of pharmaceutical properties on treatment outcomes. The present study investigated the inter-subject variability of paclitaxel binding to proteins in patient ascites because some PM patients show accumulation of ascites and because activity and transport of highly protein-bound drugs such as paclitaxel are affected by protein binding. Ascites samples were collected from 26 patients and investigated for their protein contents using LC/MS/MS proteomics analysis and for the concentrations of total proteins and two major paclitaxel-binding proteins (human serum albumin or HSA and α-1-acid glycoprotein or AAG). The association constants of paclitaxel to HSA and AAG and the extent of protein binding of paclitaxel in patient ascites were studied using equilibrium dialysis. Proteomic analysis of four randomly selected samples revealed 288 proteins, >90% of which are also present in human plasma. Between 72% - 94% of paclitaxel was bound to proteins in patient ascites. The concentrations of HSA and AAG in ascites showed substantial inter-subject variations, ranging from 14.7 - 46.3 mg/mL and 0.13-2.56 mg/mL, respectively. The respective paclitaxel association constants to commercially available HSA and AAG were âˆ¼ 3.5 and âˆ¼ 120 mM. Calculation using these constants and the HSA and AAG concentrations in individual patient ascites indicated that these two proteins accounted for >85% of the total protein-binding of paclitaxel in ascites. The extensive drug binding to ascites proteins, by reducing the pharmacologically active free fraction, may lead to the diminished CRS efficacy in PM patients with ascites. Clinical advances in CRS + IPC have outpaced current knowledge of pharmaceutical properties in this setting. IPC, as a locally acting therapy, is subjected to processes different from those governing systemic treatments. This study, to our knowledge, is the first to illustrate the implications of drug properties in the CRS + IPC efficacy against PM. While drugs are now an integral part of PM patient management, there is limited pharmaceutical research in this treatment setting (e.g., effects of hyperthermia or pressure on drug transport or release from delivery systems, pharmacokinetics, pharmacodynamics). Hence, CRS + IPC of PM represents an area where additional pharmaceutical research can assist further development and optimization.

Successful Treatment of Cirrhotic Chylous Ascites using Orlistat and Dietary Modifications: A Case Study and Literature Review.

BACKGROUND Chylous ascites (chyloperitoneum), a condition arising from lymphatic leakage in the peritoneal cavity, is rare in liver cirrhosis patients, accounting for less than 1% of cases. Treatment typically involves therapeutic paracentesis, dietary modifications, a low-fat, high-protein diet, and medium-chain triglyceride (MCT) supplementation. Orlistat, a fat absorption inhibitor, has been reported to show potential efficacy in treating chylous ascites. CASE REPORT We detail the case of a 59-year-old male patient admitted for decompensated liver disease and worsening ascites. Diagnostic paracentesis identified chylous ascites, indicated by a 3.5 mmol/L triglyceride level. Despite administering therapeutic paracentesis, dietary modifications, MCT supplementation, Spironolactone, and Terlipressin for a presumed hepatorenal syndrome, the patient's ascites remained chylous for two weeks. On administering orlistat, a significant reduction in ascites volume and chylous content was observed, with triglyceride levels dropping to 0.7 mmol/L. CONCLUSIONS Our case illustrates the potential of orlistat in managing chylous ascites in liver cirrhosis patients, marking only the second such case reported in the existing literature. It encourages further exploration of orlistat's therapeutic potential in treating chylous ascites.

Peroxisome proliferator-activated receptor gamma (PPARγ) activation: a potential treatment for ascites syndrome in broiler chickens.

Ascites (serous fluid accumulation in the abdominal cavity) has been observed worldwide in fast growing broilers. Pulmonary vascular remodeling is an important pathological feature of broiler ascites syndrome. Peroxisome proliferators-activated receptor gamma (PPARγ) and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) are expressed in pulmonary vascular endothelial cells and vascular smooth muscle cells (VSMC) where they participate in the regulation of normal pulmonary vascular function. The objective of the present study was to investigate the effects of omega-3 fatty acids (found in fish oil) and pioglitazone (PIO) as natural and synthetic PPARγ ligands supplementation on PPARγ and PGC-1α expression in the prevention of pulmonary arterial hypertension (PAH) syndrome in broiler chickens. The experiment was conducted with 4 treatment groups: 1) negative control, normal temperature conditions with basal diet; 2) positive control, low-temperature conditions with basal diet; 3) positive control + 10 mg PIO/kg of weight/d and 4) positive control + 1% FO. Each treatment had 5 replicates. Ascites heart index (RV/TV) was significantly (P < 0.05) reduced in chickens receiving FO (0.20) and PIO (0.21) compared to the positive control group (0.26). The addition of PIO in broilers under cold-induced ascites significantly increased the expression of PPARγ (9.44) and PGC-1α (5.81) genes in lung tissue compared to the negative control group (1.03, P < 0.05). Proliferative indexes of VSMC in pulmonary arteries such as PMT, PIT, and percentage wall thickness were significantly elevated in positive control group, indicating that pulmonary vascular remodeling occurred following VSMC proliferation in ascites. The vessel internal diameter was increased in FO and PIO groups. Based on these results, activation and expression of PPARγ and PGC-1α genes as a critical regulator of pulmonary artery smooth muscle cell using ligands, especially PIO, can be effective in reducing the incidence of PAH in broiler chickens.

Anticancer potential of Nymphaea nouchali Brum flowers against Ehrlich ascites carcinoma cell lines.

Background: Nymphaea nouchali Brum is exotic and medicinal plant in India. Aim of the Study: The main of this study is to evaluate the anticancer properties of Nymphaea nouchali Brum flowers against Ehrlich ascites carcinoma (EAC)-induced Swiss albino mice. Materials and Methods: The anticancer properties of Nymphaea nouchali Brum dry and fresh methanol extracts was investigated using EAC in Swiss albino mice. After inoculation of EAC cells into mice, treatment with NNDM flower extract (200 and 400 mg/kg) and standard drug 5-Fluorouracil (20 mg/kg) was continued for 9 days. The evaluation of the effect of drug response was made by the study of tumor growth response including increase in lifespan, the study of hematological parameters, biochemical estimations, and antioxidant assay of liver tissue compared to EAC control. The viability of cancer cell lines (such as HeLa, MCF-7, and MDA-MB 231 cells) was evaluated by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay. Results: Therefore, from the results of the present study, it can be concluded that NNDM exhibited significant antitumor activity against EAC in Swiss albino mice. The effect of NNDM on viability of cancer cell lines (such as HeLa, MCF-7, and MDA-MB 231 cells) was evaluated by MTT assay, apoptosis in HeLa cell lines was evaluated by DNA laddering assay, HeLa cells treated with NNDM exhibited a characteristic "ladder" pattern after separation of the fragments by agarose gel electrophoresis and subsequent visualization, by ethidium bromide staining. NNDM exhibited a significant effect on cell viability. Conclusions: Based on results, it was concluded that NNDM exhibited cytotoxic effect on cancer cells and, from DNA laddering assay, it can be concluded that NNDM-induced apoptosis in EAC cells.

Liver cirrhosis following oxaliplatin-based adjuvant chemotherapy for rectal cancer.

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.

The role of oxidative stress parameters in the differential diagnosis of malignant and benign ascites.

OBJECTIVE: Ascites is the pathological fluid accumulation in the peritoneal cavity and there are mainly two reasons for its etiology. These are malignant diseases such as hepatoma or pancreas cancer and benign diseases such as liver cirrhosis and heart failure. In this study, we investigated the diagnostic utility of arylesterase (ARES), paraoxonase (PON), stimulated paraoxonase (SPON), catalase (CAT) and myeloperoxidase (MPO) in the differential diagnosis of malignant and benign ascites. PATIENTS AND METHODS: This study was conducted between February and September 2016. Patients with acute infection, those taking vitamin supplements and antioxidant medication, smoking, and drinking alcohol were excluded from the study. RESULTS: The study population consisted of 60 patients: 36 had benign (60%) and 24 had malignant (40%) ascites. The mean age of the patients was 63.3 years. MPO levels (14.2 vs. 4.2; p=0.028) were found to be higher and PON (2.6 vs. 4.5; p<0.001), SPON (10.7 vs. 23.9; p<0.001), ARES (615.7 vs. 823.5, p<0.001) and CAT (13.3 vs. 36.8; p=0.044) were found to be lower in malignant patients compared to benign patients. There was a positive correlation between PON, SPON, and ARES levels, and a negative correlation between MPO levels and SPON, ARES, and CAT levels. MPO levels showed superior diagnostic performance compared to ARES and CAT levels (p<0.05) for predicting malignancy but showed no diagnostic superiority compared to PON and SPON levels (p>0.05). CONCLUSIONS: PON, SPON, ARES, CAT, and MPO can be used with high sensitivity and specificity in the differential diagnosis of malignant and benign ascites.

Clinical outcomes associated with complementary and alternative medicine-related "immunity-boosting" practices in patients with cirrhosis during the COVID-19 pandemic - an observational study.

During the coronavirus disease 2019 pandemic, Ayurvedic herbal supplements and homeopathic immune boosters (IBs) were promoted as disease-preventive agents. The present study examined the clinical outcomes among patients with chronic liver disease who presented with complications of portal hypertension or liver dysfunction temporally associated with the use of IBs in the absence of other competing causes. This single-center retrospective observational cohort study included patients with chronic liver disease admitted for the evaluation and management of jaundice, ascites, or hepatic encephalopathy temporally associated with the consumption of IBs and followed up for 180 days. Chemical analysis was performed on the retrieved IBs. From April 2020 to May 2021, 1022 patients with cirrhosis were screened, and 178 (19.8%) were found to have consumed complementary and alternative medicines. Nineteen patients with cirrhosis (10.7%), jaundice, ascites, hepatic encephalopathy, or their combination related to IBs use were included. The patients were predominantly male (89.5%). At admission, 14 (73.75%) patients had jaundice, 9 (47.4%) had ascites, 2 (10.5%) presented with acute kidney injury, and 1 (5.3%) had overt encephalopathy. Eight patients (42.1%) died at the end of the follow up period. Hepatic necrosis and portal-based neutrophilic inflammation were the predominant features of liver biopsies. IB analysis revealed detectable levels of (heavy metals) As (40%), Pb (60%), Hg (60%), and various hepatotoxic phytochemicals. Ayurvedic and Homeopathic supplements sold as IBs potentially cause the worsening of preexisting liver disease. Responsible dissemination of scientifically validated, evidence-based medical health information from regulatory bodies and media may help ameliorate this modifiable liver health burden.

Update in the Treatment of the Complications of Cirrhosis.

Cirrhosis consists of 2 main stages: compensated and decompensated, the latter defined by the development/presence of ascites, variceal hemorrhage, and hepatic encephalopathy. The survival rate is entirely different, depending on the stage. Treatment with nonselective ß-blockers prevents decompensation in patients with clinically significant portal hypertension, changing the previous paradigm based on the presence of varices. In patients with acute variceal hemorrhage at high risk of failure with standard treatment (defined as those with a Child-Pugh score of 10-13 or those with a Child-Pugh score of 8-9 with active bleeding at endoscopy), a pre-emptive transjugular intrahepatic portosystemic shunt (TIPS) improves the mortality rate and has become the standard of care in many centers. In patients with bleeding from gastrofundal varices, retrograde transvenous obliteration (in those with a gastrorenal shunt) and/or variceal cyanoacrylate injection have emerged as alternatives to TIPS. In patients with ascites, emerging evidence suggests that TIPS might be used earlier, before strict criteria for refractory ascites are met. Long-term albumin use is under assessment for improving the prognosis of patients with uncomplicated ascites and confirmatory studies are ongoing. Hepatorenal syndrome is the least common cause of acute kidney injury in cirrhosis, and first-line treatment is the combination of terlipressin and albumin. Hepatic encephalopathy has a profound impact on the quality of life of patients with cirrhosis. Lactulose and rifaximin are first- and second-line treatments for hepatic encephalopathy, respectively. Newer therapies such as L-ornithine L-aspartate and albumin require further assessment.
