Midodrine plus propranolol versus propranolol alone in preventing first bleed in patients with cirrhosis and severe ascites: a randomized controlled trial.

Propranolol, a non-selective beta-blocker, commonly used to prevent variceal bleed, but might precipitate circulatory dysfunction in severe ascites. Midodrine, an alpha-1 adrenergic agonist improves renal perfusion and systemic hemodynamics. Addition of midodrine might facilitate higher maximum tolerated dose (MTD) of propranolol, thereby less risk of variceal bleed in cirrhosis patients with severe ascites. 140 patients with cirrhosis and severe/refractory ascites were randomized- propranolol and midodrine (Gr.A,n = 70) or propranolol alone (Gr.B,n = 70). Primary outcome was incidence of bleed at 1year. Secondary outcomes included ascites control, achievement of target heart rate (THR), HVPG response and adverse effects. Baseline characteristics were comparable between two groups. Cumulative incidence of bleed at 1year was lower in Gr.A than B (8.5%vs.27.1%,p-0.043). The MTD of propranolol was higher in Gr.A (96.67 ± 36.6mg vs. 76.52 ± 24.4mg; p-0.01) and more patients achieved THR (84.2%vs.55.7%,p-0.034). Significantly higher proportion of patients in Gr.A had complete resolution of ascites [17.1%vs.11.4%,p-0.014), diuretic tolerance (80%vs.60%,p-0.047) at higher doses(p-0.02) and lesser need for paracentesis. Patients in Gr.A also had greater reduction in variceal grade (75.7%vs.55.7%;p-0.01), plasma renin activity (54.4% from baseline) (p = 0.02). Mean HVPG reduction was greater in Gr.A than B [4.38 ± 2.81mmHg(23.5%) vs. 2.61 ± 2.87mmHg(14.5%),p-0.045]. Complications like post-paracentesis circulatory dysfunction and spontaneous bacterial peritonitis on follow-up were higher in Gr.B than A (22.8%vs.51.4%,p = 0.013 and 10%vs.15.7%, p = 0.03, respectively). Addition of midodrine facilitates effective use of propranolol in higher doses and greater HVPG reduction, thereby preventing first variceal bleed, reduced paracentesis requirements with fewer ascites- related complications in patients with cirrhosis with severe/refractory ascites.

Critical care outcomes in decompensated cirrhosis: a United States national inpatient sample cross-sectional study

BackgroundPrior assessments of critical care outcomes in patients with cirrhosis have shown conflicting results. We aimed to provide nationwide generalizable results of critical care outcomes in patients with decompensated cirrhosis.MethodsThis is a retrospective study using the National Inpatient Sample from 2016 to 2019. Adults with cirrhosis who required respiratory intubation, central venous catheter placement or both (n = 12,945) with principal diagnoses including: esophageal variceal hemorrhage (EVH, 24%), hepatic encephalopathy (58%), hepatorenal syndrome (HRS, 14%) or spontaneous bacterial peritonitis (4%) were included. A comparison cohort of patients without cirrhosis requiring intubation or central line placement for any principal diagnosis was included.ResultsThose with cirrhosis were younger (mean 58 vs. 63 years, p < 0.001) and more likely to be male (62% vs. 54%, p < 0.001). In-hospital mortality was higher in the cirrhosis cohort (33.1% vs. 26.6%, p < 0.001) and ranged from 26.7% in EVH to 50.6% HRS. Mortality when renal replacement therapy was utilized (n = 1580, 12.2%) was 46.5% in the cirrhosis cohort, compared to 32.3% in other hospitalizations (p < 0.001), and was lowest in EVH (25.7%) and highest in HRS (51.5%). Mortality when cardiopulmonary resuscitation was used was increased in the cirrhosis cohort (88.0% vs. 72.1%, p < 0.001) and highest in HRS (95.7%).ConclusionsOne-third of patients with cirrhosis requiring critical care did not survive to discharge in this U.S. nationwide assessment. While outcomes were worse than in patients without cirrhosis, the results do suggest better outcomes compared to previous studies.

Dynamic liver volume change in predicting hepatic decompensation and long-term effects of stereotactic body radiation therapy.

This study aimed to investigate the association between liver volume change and hepatic decompensation and compare the risk of hepatic decompensation in patients with liver cirrhosis (LC) and hepatocellular carcinoma (HCC) who underwent stereotactic body radiation therapy (SBRT). A retrospective review of SBRT-treated HCC and compensated LC without HCC patients was conducted. Liver volume was measured using auto-segmentation software on liver dynamic computed tomography scans. The decompensation event was defined as the first occurrence of refractory ascites, esophageal variceal bleeding, hepatic encephalopathy, or spontaneous bacterial peritonitis. We evaluated the association between the rate of liver volume decrease and hepatic decompensation and compared decompensation events between the SBRT and LC cohorts using propensity score matching. A total of 138 patients from the SBRT cohort and 488 from the LC cohort were analyzed. The rate of liver volume decrease was associated with the risk of decompensation events in both cohorts. The 3-year rate of decompensation events was significantly higher in the group with a liver volume decreasing rate>7%/year compared with the group with a rate<7%/year. In the propensity score-matched cohort, the 3-year rate of decompensation events after a single session of SBRT was not significantly different from that in the LC cohort. The rate of liver volume decrease was significantly associated with the risk of hepatic decompensation in both HCC patients who received SBRT and LC patients. A single session of SBRT for HCC did not result in a higher decompensation rate compared with LC.

Clinical evaluation of droplet digital pcr for suspected ascites infection in patients with liver cirrhosis.

Droplet digital PCR (ddPCR) is increasingly used in diagnosing clinical pathogens, but its effectiveness in cirrhosis patients with suspected ascites infection remains uncertain. The diagnostic performance of ddPCR was assessed in 305 ascites samples, utilizing culture and clinical composite standards. The quantitative value and potential clinical impact of ddPCR were further analyzed in patients with spontaneous bacterial peritonitis. With culture standards, ddPCR demonstrated a sensitivity of 86.5% and specificity of 83.2% for bacterial or fungal detection. After adjustment of clinical composite criteria, specificity increased to 96.4%. Better diagnostic performance for all types of targeted pathogens, particularly fungi, was observed with ddPCR compared to culture, and more polymicrobial infections were detected (30.4% versus 5.7%, p < 0.001). Pathogen loads detected by ddPCR correlated with white blood cell count in ascites and blood, as well as polymorphonuclear cell (PMN) count in ascites, reflecting infection status rapidly. A positive clinical impact of 55.8% (43/77) was observed for ddPCR, which was more significant among patients with PMN count ≤ 250/mm3 in terms of medication adjustment and new diagnosis. ddPCR results for fungal detection were confirmed by clinical symptoms and other microbiological tests, which could guide antifungal therapy and reduce the risk of short-term mortality. ddPCR, with appropriate panel design, has advantages in pathogen detection and clinical management of ascites infection, especially for patients with fungal and polymicrobial infections. Patients with atypical spontaneous bacterial peritonitis benefited more from ddPCR.

Cost-effectiveness of albumin in the treatment of decompensated cirrhosis in resource-limited healthcare settings.

Human albumin (HA) is an effective adjuvant treatment for patients with cirrhosis developing spontaneous bacterial peritonitis (SBP), hepatorenal syndrome (HRS) and ascites requiring large-volume paracentesis (LVP). However, cost remains a barrier to use, particularly in resource-limited settings. This study aims to assess the cost-effectiveness of HA in patients with cirrhosis with SBP, HRS or ascites requiring LVP in the Indonesian healthcare system as a representative of a resource-limited setting. Three decision-tree models were developed to assess the cost-effectiveness of (1) antibiotics and HA versus antibiotics alone in patients with SBP, (2) terlipressin and HA versus terlipressin alone in patients with HRS, and (3) LVP and HA versus LVP and gelatine for patients with ascites. Clinical utility and economic inputs were pooled from the available literature. Time horizon was 3 months. Outcomes were expressed as incremental cost-effectiveness ratios (ICER) reported as 2021 IDR per quality-adjusted life year (QALY) (exchange rate June 30, 2021: 1 EUR = 17,245 IDR). Willingness-to-pay thresholds considered were: three times the GDP per capita (199,355,561 IDR/QALY; 11,560 EUR/QALY) and one time the GDP per capita (66,451,854 IDR/QALY; 3853 EUR/QALY). The ICER for antibiotics and HA (versus antibiotics alone) for SBP was 80,562,652 IDR per QALY gained (4672 EUR/QALY). The ICER for terlipressin and HA (versus terlipressin) for HRS was 23,085,004 IDR per QALY gained (1339 EUR/QALY). The ICER for LVP and HA versus LVP and gelatine was 24,569,827 IDR per QALY gained (1425 EUR/QALY). Adjunctive HA may be a cost-effective treatment for SBP, HRS and LVP in resource-limited settings.

Beta-blockers or Placebo for Primary Prophylaxis (BOPPP) of oesophageal varices: study protocol for a randomised controlled trial

BackgroundLiver disease is within the top five causes of premature death in adults. Deaths caused by complications of cirrhosis continue to rise, whilst deaths related to other non-liver disease areas are declining. Portal hypertension is the primary sequelae of cirrhosis and is associated with the development of variceal haemorrhage, ascites, hepatic encephalopathy and infection, collectively termed hepatic decompensation, which leads to hospitalisation and mortality. It remains uncertain whether administering a non-selective beta-blocker (NSBB), specifically carvedilol, at an earlier stage, i.e. when oesophageal varices are small, can prevent VH and reduce all-cause decompensation (ACD).Methods/designThe BOPPP trial is a pragmatic, multicentre, placebo-controlled, triple-blinded, randomised controlled trial (RCT) in England, Scotland, Wales and Northern Ireland. Patients aged 18 years or older with cirrhosis and small oesophageal varices that have never bled will be recruited, subject to exclusion criteria. The trial aims to enrol 740 patients across 55 hospitals in the UK. Patients are allocated randomly on a 1:1 ratio to receive either carvedilol 6.25 mg (a NSBB) or a matched placebo, once or twice daily, for 36 months, to attain adequate power to determine the effectiveness of carvedilol in preventing or reducing ACD.The primary outcome is the time to first decompensating event. It is a composite primary outcome made up of variceal haemorrhage (VH, new or worsening ascites, new or worsening hepatic encephalopathy (HE), spontaneous bacterial peritonitis (SBP), hepatorenal syndrome, an increase in Child–Pugh grade by 1 grade or MELD score by 5 points, and liver-related mortality. Secondary outcomes include progression to medium or large oesophageal varices, development of gastric, duodenal, or ectopic varices, participant quality of life, healthcare costs and transplant-free survival.DiscussionThe BOPPP trial aims to investigate the clinical and cost-effectiveness of carvedilol in patients with cirrhosis and small oesophageal varices to determine whether this non-selective beta-blocker can prevent or reduce hepatic decompensation. There is clinical equipoise on whether intervening in cirrhosis, at an earlier stage of portal hypertension, with NSBB therapy is beneficial. Should the trial yield a positive result, we anticipate that the administration and use of carvedilol will become widespread with pathways developed to standardise the administration of the medication in primary care.Ethics and disseminationThe trial has been approved by the National Health Service (NHS) Research Ethics Committee (REC) (reference number: 19/YH/0015). The results of the trial will be submitted for publication in a peer-reviewed scientific journal. Participants will be informed of the results via the BOPPP website (www.boppp-trial.org) and partners in the British Liver Trust (BLT) organisation.Trial registrationEUDRACT reference number: 2018–002509-78.ISRCTN reference number: ISRCTN10324656. Registered on April 24 2019.

Side effects of proton pump inhibitors: how real are they in clinical practice?

The presented article discusses the risk of side eff ects when using proton pump inhibitors (PPI): infectious complications (small intestinal bacterial overgrowth, Clostridium difficile-associated disease, community-acquired pneumonia, spontaneous bacterial peritonitis), stomach cancer, myocardial infarction, hypomagnesemia, iron and vitamin B12 deficiency, kidney damage, bone fractures, dementia, Alzheimer’s disease. An analysis of the literature indicates a weak causal relationship between the occurrence of these diseases and the use of PPI. Nevertheless, it is necessary to strive for the appointment of these drugs in the minimum effective dose and for as short a time as possible.

Albumin: a comprehensive review and practical guideline for clinical use.

Nowadays, it is largely accepted that albumin should not be used in hypoalbuminemia or for nutritional purpose. The most discussed indication of albumin at present is the resuscitation in shock states, especially distributive shocks such as septic shock. The main evidence-based indication is also liver disease. In this review, we provided updated evidence-based instruction for definite and potential indications of albumin administration in clinical practice, with appropriate dosing and duration. Data collection was carried out until November 2023 by search of electronic databases including PubMed, Google Scholar, Scopus, and Web of Science. GRADE system has been used to determine the quality of evidence and strength of recommendations for each albumin indication. A total of 165 relevant studies were included in this review. Fluid replacement in plasmapheresis and liver diseases, including hepatorenal syndrome, spontaneous bacterial peritonitis, and large-volume paracentesis, have a moderate to high quality of evidence and a strong recommendation for administering albumin. Moreover, albumin is used as a second-line and adjunctive to crystalloids for fluid resuscitation in hypovolemic shock, sepsis and septic shock, severe burns, toxic epidermal necrolysis, intradialytic hypotension, ovarian hyperstimulation syndrome, major surgery, non-traumatic brain injury, extracorporeal membrane oxygenation, acute respiratory distress syndrome, and severe and refractory edema with hypoalbuminemia has a low to moderate quality of evidence and weak recommendation to use. Also, in modest volume paracentesis, severe hyponatremia in cirrhosis has a low to moderate quality of evidence and a weak recommendation. Albumin administration is most indicated in management of cirrhosis complications. Fluid resuscitation or treatment of severe and refractory edema, especially in patients with hypoalbuminemia and not responding to other treatments, is another rational use for albumin. Implementation of evidence-based guidelines in hospitals can be an effective measure to reduce inappropriate uses of albumin.

Manual method versus flow cytometry for diagnosing spontaneous bacterial peritonitis

ABSTRACT Background Diagnosing spontaneous bacterial peritonitis (SBP) requires a high clinical index of suspicion because the clinical presentation varies widely. Early detection and treatment of SBP are crucial for improving survival rates. Ascitic fluid neutrophil count ≥ 250 cells/mm3 is the only required criterion to diagnose SBP, regardless of culture results. The most frequently used manual ascitic neutrophil counting is difficult and time-consuming, and it often leads to frequent delays in obtaining results and a possible under- or overestimation of the neutrophilic count. The flow cytometric counting provides results in 30 minutes and is more accurate, with sensitivity and specificity approaching 100%. Objective This study aimed to assess the diagnostic efficacy of manual counting of neutrophils in comparison to flow cytometry for detecting SBP. Patients and methods In a cross-sectional study, we included 140 cirrhosis-related ascites patients who were clinically suspected to have SBP and admitted to the Alexandria Main University Hospital in the Department of Internal Medicine. Participants with ≥ 250 neutrophil cells/mm3 in ascitic fluid by flow cytometry were defined as SBP patients. In contrast, those with fewer than 250 neutrophil cells/mm3 in ascitic fluid using the flow cytometric method were defined as patients without SBP. Results At a cutoff value of 250 cells/mm3, the ROC curve showed that the manual ascitic fluid method had lower sensitivity, specificity, positive and negative predictive values (67.19%, 86.84%, 81.13%, and 75.86%, respectively, with AUC = 0.945, 95% CI, 0.91–0.97, p < 0.001) in diagnosing SBP than the flow cytometric method. Conclusions Using the flow cytometric method significantly improved diagnostic precision. Its use may be recommended to replace the traditional manual method, which may have unaccepted false-negative results.

Decompensated liver cirrhosis: assessment of complications and mortality in hospitalised patients

Background. Liver cirrhosis is a severe, progressively fatal disease if untreated. Hospitalised patients face high mortality rates, and current methods for assessing prognosis vary widely. The research aims to investigate complications and predictors of mortality in patients admitted for decompensated cirrhosis to a tertiary care centre in Tirana, Albania. Materials and methods. The retrospective study included 212 patients aged (58.67 ± 10.09) years: 174 (82.1 %) men, 38 (17.9 %) women. The Child-Turcotte-Pugh, MELD, MELD-Na, MELD 3.0, iMELD, MESO, and UKELD scales were used to assess the severity of the condition and risk stratification of patients. The number of patients with a fatal outcome was 43 (20.3 %). Results. Among participants with different etiological factors of liver cirrhosis, the mortality rate did not differ significantly (p = 0.873). The presence of hepatic encepha­lopathy (0.43; p = 0.001), acute-on-chronic liver failure (r = 0.47; p = 0.001) and hepatorenal syndrome (r = 0.49; p = 0.001), and, to a lesser extent, ascites (r = 0.18; p = 0.006) and spontaneous bacterial peritonitis (r = 0.23; p = 0.041) was a marker of unfavourable prognosis of hospitalisation. Also, the risk of death increased in the presence of leukaemia (hazard ratio = 4.21 (1.65; 10.74); p = 0.003). Conclusions. The MELD 3.0 and MELD-Na scores, calculated based on laboratory values obtained within 48–72 hours of hospitalisation, were found to be the prognostically significant (p &lt; 0.05)

Neutrophil percentage-to-albumin ratio is a new diagnostic marker for spontaneous bacterial peritonitis: a prospective multicenter study

BackgroundThe neutrophil percentage-to-albumin ratio (NPAR) is a novel measure of systemic inflammation and infection. Low albumin levels increase the risk of infection, while high neutrophil counts indicate the presence of infection. Spontaneous bacterial peritonitis (SBP) is a serious infection in cirrhotic ascites, and the potential of NPAR in diagnosing SBP is not yet established.ObjectiveThe objective of this study is to determine the diagnostic value of NPAR in identifying SBP.PatientsThis prospective multicenter study included 465 patients diagnosed with cirrhotic ascites and SBP according to international guidelines. Demographic, clinical, and laboratory data were collected. The sensitivity and specificity of NPAR values for diagnosing SBP were assessed using the receiver operating characteristic curve.ResultsFor SBP diagnosis in the total cohort, NPAR of > 17 had a sensitivity of 85.71%, specificity of 66.67%, and 95% CI (42.1–99.6). In culture-positive SBP, the NPAR at a cut-off > 5.2 had a sensitivity of 85.71%, specificity of 83.33%, and 95% CI (0.709 to 0.979), while in culture-negative SBP, the NPAR at a cut-off > 2.1 had a sensitivity of 92.86%, specificity of 33.33% and CI (0.367 to 0.764). The multivariate analysis revealed that albumin (OR = 2.78, [1.11;3.98], INR (OR = 0.198, [0.066;0.596], creatinine (OR = 0.292, [0.1; 0.81], CRP (OR = 3.18, [1.239;4.52] total leukocytic count (TLC) (OR = 1.97, [1.878; 2.07], platelets (OR = 2.09, [0.99; 2.31] and neutrophil (OR = 3.43, [1.04;3.89] were significantly associated with higher prediction rates for culture positive SBP.ConclusionsNPAR could be a new, affordable, noninvasive test for diagnosing SBP.

Listeria monocytogenes-associated spontaneous bacterial peritonitis in France: a nationwide observational study of 208 cases

Listeriosis is a foodborne infection caused by Listeria monocytogenes. Three main forms of listeriosis are well characterised, but little is known about L monocytogenes-associated spontaneous bacterial peritonitis. We used data from the French national surveillance of listeriosis to perform a nationwide retrospective study. All patients with L monocytogenes isolated by culture from a peritoneal fluid sample in France between April 1, 1993, and Dec 31, 2022, were included. Individuals for whom bacterial peritonitis was not confirmed and those who also had another type of invasive listeriosis were excluded. A standardised checklist was used to collect demographic, clinical, and biological data as well as antibiotic treatment and follow-up data. The primary outcome was to determine the characteristics of L monocytogenes-associated spontaneous bacterial peritonitis. We did descriptive analyses and assessed risk factors for 1-month mortality using an exploratory multivariable Cox model analysis. Among the 8768 L monocytogenes cases reported, 208 (2%) were patients with L monocytogenes-associated spontaneous bacterial peritonitis. Mean age was 65 years (SD 13), 50 (24%) of 208 patients were female, and 158 (76%) were male (no data on race or ethnicity were available). 200 (98%) of 205 patients with L monocytogenes-associated spontaneous bacterial peritonitis with available data had immunosuppressive comorbidities, including cirrhosis (148 [74%] of 201 with available data), ongoing alcoholism (58 [62%] of 94), and ongoing neoplasia (60 [31%] of 195). Causes of ascites included cirrhosis (146 [70%] of 208), ongoing neoplasia (26 [13%]), end-stage heart failure (13 [6%]), and peritoneal dialysis (11 [5%]). Among those with available data, presentation was pauci-symptomatic and non-specific; only 67 (50%) of 135 patients presented with fever, 49 (37%) of 132 with abdominal pain, and 27 (21%) of 129 with diarrhoea. 61 (29%) of 208 patients were dead at 1 month, 92 (44%) were dead at 3 months, and 109 (52%) were dead at 6 months after diagnosis. Ongoing neoplasia (hazard ratio 2·42 [95% CI 1·05-5·56]; p=0·039), septic shock (8·03 [2·66-24·02]; p=0·0021), and high blood leukocyte count (1·05 [1·00-1·09]; p=0·045) were independently associated with 1-month mortality. Despite the non-specific and mild presentation of L monocytogenes-associated spontaneous bacterial peritonitis, the outcome is poor and similar to that of neurolisteriosis, and so identification of L monocytogenes in ascitic fluid samples requires urgent parenteral amoxicillin-based treatment to avoid a fatal outcome.

Retrospective study of the incidence, risk factors, treatment outcomes of bacterial infections at uncommon sites in cirrhotic patients.

Bacterial infections (BI) negatively affect the natural course of cirrhosis. The most frequent BI are urinary tract infections (UTI), pneumonia, and spontaneous-bacterial peritonitis (SBP). To assess the relevance of bacterial infections beyond the commonly recognized types in patients with cirrhosis and to investigate their relationship with other clinical variables. We retrospectively analyzed patients with cirrhosis and BI treated between 2015 and 2018 at our tertiary care center. BIs were classified as typical and atypical, and clinical as well as laboratory parameters were compared between the two groups. In a cohort of 488 patients with cirrhosis, we identified 225 typical BI (95 UTI, 73 SBP, 72 pulmonary infections) and 74 atypical BIs, predominantly cholangitis and soft tissue infections (21 each), followed by intra-abdominal BIs (n = 9), cholecystitis (n = 6), head/throat BIs (n = 6), osteoarticular BIs (n = 5), and endocarditis (n = 3). We did not observe differences concerning age, sex, or etiology of cirrhosis in patients with typical vs atypical BI. Atypical BIs were more common in patients with more advanced cirrhosis, as evidenced by Model of End Stage Liver Disease (15.1 ± 7.4 vs 12.9 ± 5.1; P = 0.005) and Child-Pugh scores (8.6 ± 2.5 vs 8.0 ± 2; P = 0.05). Atypical BIs in cirrhosis patients exhibit a distinct spectrum and are associated with more advanced stages of the disease. Hence, the work-up of cirrhosis patients with suspected BI requires detailed work-up to elucidate whether typical BI can be identified.

Assessment of the 2021 AASLD Practice Guidance for Albumin Infusion in Elective Therapeutic Paracentesis: A Regression Discontinuity Design.

The 2021 American Association for the Study of Liver Disease (AASLD) Practice Guidance recommends albumin infusion when removing ≥ 5 liters of ascites to prevent post-paracentesis circulatory dysfunction. However, the optimal criteria and scenarios for initiating albumin infusion subsequent to therapeutic paracentesis (TP) have been subject to limited scientific inquiry. We conducted a retrospective cohort study at a U.S. academic healthcare center. Participants received elective, outpatient TP between July 2019 and December 2022. Patients with spontaneous bacterial peritonitis, post-TP clinical adjustments, and/or hospitalization were excluded. The institution strictly followed the AASLD Guidance. We employed a sharp regression discontinuity (RD) design to estimate the effect of albumin infusion at the AASLD Guidance-recommended cutoff of 5 liters on serum creatinine and sodium trajectory post-TP. Over the study period, 1457 elective TPs were performed on 235 unique patients. Albumin infusion at the threshold of 5 liters of ascites removal reduced serum creatinine levels by 0.046 mg/dl/day (95% CI: 0.003 to 0.116, p-value=0.037) and increased serum sodium levels by 0.35 mEq/L/day (95% CI: 0.15-0.55, p=0.001) compared to those who did not receive albumin infusion. The RD plots indicated worsened serum creatine/sodium levels after draining 3 liters of fluid, approaching levels similar to or worse than with albumin infusion at 5 liters or more. Our RD models supported the 2021 AASLD Guidance with robust estimation of causal effect sizes at the cutoff level of 5 liters. Nevertheless, the findings also highlight the need to further evaluate the efficacy of albumin infusion in patients who undergo elective TP and have 3-5 liters of ascites removed.
