Meta-Analysis Review
BACKGROUND
Severe dengue is a life-threatening complication; rapid identification of these cases, followed by adequate management is crucial to improve the clinical prognosis. Therefore, this study aimed to identify risk factors and predictors of severe dengue.
METHODS
A literature search for studies reporting risk factors of severe dengue among individuals with dengue virus infection was conducted in PubMed, Scopus and Web of Science database from inception to December 31, 2020. Pooled odds ratios (ORs) for patients' demographic characteristics, co-morbidities, and warning signs were estimated using an inverse variance heterogeneity model.
RESULTS
We included 143 articles in the meta-analysis from a total of 13 090 articles retrieved from the literature search. The risk factors of severe dengue were: being a child [OR = 1.96; 95% confidence interval (CI): 1.22-3.13], secondary infection (OR = 3.23; 95% CI: 2.28-4.57), and patients with pre-existing diabetes (OR = 2.88; 95% CI: 1.72-4.81) and renal disease (OR = 4.54; 95% CI: 1.55-13.31). Warning signs strongly associated with severe disease were increased haematocrit with a concurrent decrease in platelet count (OR = 5.13; 95% CI: 1.61-16.34), abdominal pain (OR = 2.00; 95% CI: 1.49-2.68), lethargy (OR = 2.73; 95% CI: 1.05-7.10), vomiting (OR = 1.80; 95% CI: 1.43-2.26), hepatomegaly (OR = 5.92; 95% CI: 3.29-10.66), ascites (OR = 6.30; 95% CI: 3.75-10.60), pleural effusion (OR = 5.72; 95% CI: 3.24-10.10) and melena (OR = 4.05; 95% CI: 1.64-10.00).
CONCLUSIONS
Our meta-analysis identified children, secondary infection, diabetes and renal disease(s) as important predictors of severe dengue. Our finding also supports the predictive ability of the WHO warning signs to identify severe dengue. These findings are useful for clinicians to identify severe dengue for management and timely interventions.

Review
UNLABELLED
At present, polyserositis (PS) remains a challenging entity, which resides both in the fact that there is confusion regarding the terminology, and that it is still understudied. We aimed to identify the etiologies of PS, reported in adult patients.
METHODS
We performed a systematic review of the literature on PubMed(MEDLINE) database, using the following (MESH) terms: pleurisy/etiology, pleural effusion/etiology, pericarditis/etiology, pericardial effusion/etiology, pericardial effusion chronic, ascites/etiology, ascitic fluid/etiology, polyserositis, serositis, and serositides.
RESULTS
A total of 1979 articles were identified, dating from 1973 onwards. After screening the articles, we included 114 patients from 23 articles (one case series including 92 patients and 22 case reports) in the final report. The most common diagnosis was neoplasia (30; 26.3%), followed by autoimmune diseases (19, 16.7%) and infections (16, 12.3%). Still, in 35 cases, the etiology of PS remained unkown.
CONCLUSION
PS is a challenging and understudied entity, which is associated with a wide range of diagnoses. However, prospective studies should be developed in order to have a clear understanding regarding its etiologies and their prevalences.

Review
INTRODUCTION
Gastrointestinal involvement is a common complain observed in 40-60% of systemic lupus erythematosus (SLE) patients. We performed a systematic review of clinically severe and potential life-threatening gastrointestinal manifestations and discuss clinical presentation, pathogenesis and treatment.
METHODS
We performed a literature search in English literature using PubMed and Embase from 2000 to December 2020. The following MeSH terms: systemic lupus erythematosus, protein-losing enteropathy, ascites, pancreatitis, vasculitis, intestinal vasculitis, enteritis and diarrhea published in the English literature.
RESULTS
We identified 141 studies (case reports, case series and cohort studies). The most frequent presenting symptoms are acute abdominal pain, nausea, and vomiting. Many of the manifestations were associated with disease activity. Histological features are rarely available, but both vasculitis and thrombosis have been described. There is no treatment guideline. The majority of patients were treated with corticosteroids and the most common immunososupressant were azathioprine, cyclophosphamide and mycophenolate.
CONCLUSION
Vasculitis and thrombosis may be responsible for severe life-threatening manifestations such as pancreatitis, protein loosing gastroenteritis, acalculous cholecistyitis and enteritis.

Meta-Analysis
BACKGROUND & AIMS
Whether non-selective β-blockers can prevent decompensation of cirrhosis warrants clarification. Carvedilol might be particularly effective since its intrinsic vasodilatory activity may ameliorate hepatic vascular resistance, a major mechanism of portal hypertension in early cirrhosis. We assessed whether carvedilol may prevent decompensation and improve survival in patients with compensated cirrhosis and clinically significant portal hypertension (CSPH).
METHODS
By systematic review we identified randomized-controlled trials (RCTs) comparing carvedilol vs. control therapy (no-active treatment or endoscopic variceal ligation [EVL]) in patients with cirrhosis and CSPH without previous bleeding. We performed a competing-risk time-to-event meta-analysis using individual patient data (IPD) obtained from principal investigators of RCTs. Only compensated patients were included. Primary outcomes were prevention of decompensation (liver transplantation and death were competing events) and death (liver transplantation was a competing event). Models were adjusted using propensity scores for baseline covariates with the inverse probability of treatment weighting (IPTW) approach.
RESULTS
Among 125 full-text studies evaluated, 4 RCTs were eligible. The 4 provided IPD and were included, comprising 352 patients with compensated cirrhosis, 181 treated with carvedilol and 171 controls (79 received EVL and 92 placebo). Baseline characteristics were similar between groups. Standardized differences were <10% by IPTW. The risk of developing decompensation of cirrhosis was lower with carvedilol than in controls (subdistribution hazard ratio [SHR] 0.506; 95% CI 0.289-0.887; p = 0.017; I = 0.0%, Q-statistic-p = 0.880), mainly due to a reduced risk of ascites (SHR 0.491; 95% CI 0.247-0.974; p = 0.042; I = 0.0%, Q-statistic-p = 0.384). The risk of death was also lower with carvedilol (SHR 0.417; 95% CI 0.194-0.896; p = 0.025; I = 0.0%, Q-statistic-p = 0.989).
CONCLUSIONS
Long-term carvedilol therapy reduced decompensation of cirrhosis and significantly improved survival in compensated patients with CSPH. This suggests that screening patients with compensated cirrhosis for CSPH to enable the prompt initiation of carvedilol could improve outcomes.

LAY SUMMARY
The transition from compensated cirrhosis to decompensated cirrhosis is associated with markedly reduced life expectancy. Therefore, preventing decompensation in patients with compensated cirrhosis would be associated with greatly improved patient outcomes. There has been controversy regarding the use of non-selective β-blockers (portal pressure-lowering medications) in patients with cirrhosis and elevated portal blood pressure (portal hypertension). Herein, using a competing-risk meta-analysis to optimize sample size and properly investigate cirrhosis as a multistate disease and outcomes as time-dependent events, we show that carvedilol (a non-selective β-blocker) is associated with a reduced risk of decompensating events and improved survival in patients with cirrhosis and portal hypertension.

Review
BACKGROUND AND AIM
Spontaneous bacterial peritonitis is a potentially life-threatening infection in patients with liver cirrhosis and ascites. Its prevention is vital to improve prognosis of cirrhotic patients. The main objective of this systematic review was to evaluate what is the most efficacious and safest antibiotic prophylactic strategy.
METHODS
Studies were located by searching PubMed and Cochrane Central Register of Controlled Trials in The Cochrane Library until February 2019. Randomized controlled trials evaluating primary or secondary spontaneous bacterial peritonitis prophylaxis in cirrhotic patients with ascites were included. The selection of studies was performed in two stages: screening of titles and abstracts, and assessment of the full papers identified as relevant, considering the inclusion criteria. Data were extracted in a standardized way and synthesized qualitatively.
RESULTS
Fourteen studies were included. This systematic review demonstrated that daily norfloxacin is effective as a prophylactic antibiotic for the prevention of spontaneous bacterial peritonitis in patients with cirrhosis. Once weekly ciprofloxacin was not inferior to once daily norfloxacin, with good tolerance and no induced resistance. Trimethoprim-sulfamethoxazole and norfloxacin have similar efficacy for primary and secondary prophylaxis of spontaneous bacterial peritonitis, however, trimethoprim-sulfamethoxazole was associated with an increased risk of developing an adverse event. Rifaximin was more effective than norfloxacin in the secondary prophylaxis of spontaneous bacterial peritonitis, with a significant decrease in adverse events and mortality rate.
CONCLUSIONS
Continuous long-term selective intestinal decontamination with norfloxacin is the most widely used prophylactic strategy in spontaneous bacterial peritonitis, yet other equally effective and safe options are available.

Meta-Analysis Review
BACKGROUND
Portal vein thrombosis (PVT) may be associated with negative outcomes in patients with liver cirrhosis. However, the prevalence and incidence of PVT in liver cirrhosis are heterogeneous among studies and have not been sufficiently determined yet.
METHODS
The PubMed, EMBASE, and Cochrane Library databases were searched. Eligible studies would explore the prevalence and/or incidence of PVT in liver cirrhosis without hepatocellular carcinoma or abdominal surgery. Pooled proportion with 95% confidence interval (CI) was calculated using a random-effect model. Factors associated with the presence/occurrence of PVT were also extracted.
RESULTS
Among the 8549 papers initially identified, 74 were included. Fifty-four studies explored the prevalence of PVT in liver cirrhosis with a pooled prevalence of 13.92% (95%CI=11.18-16.91%). Based on cross-sectional data, Child-Pugh class B/C, higher D-dimer, ascites, and use of non-selective beta-blockers (NSBBs) were associated with the presence of PVT in liver cirrhosis. Twenty-three studies explored the incidence of PVT in liver cirrhosis with a pooled incidence of 10.42% (95%CI=8.16-12.92%). Based on cohort data, Child-Pugh class B/C, higher model of end-stage liver disease score, higher D-dimer, lower platelets count, decreased portal flow velocity, ascites, use of NSBBs, and moderate or high-risk esophageal varices could predict the occurrence of PVT in liver cirrhosis.
CONCLUSION
Approximately one seventh of cirrhotic patients have PVT, and one tenth will develop PVT. Progression of liver cirrhosis and portal hypertension seems to be in parallel with the risk of PVT. Prospective studies with detailed information about classification and extension of PVT in liver cirrhosis are needed.

Meta-Analysis
BACKGROUND
Human albumin infusion is effective for controlling systemic inflammation, thereby probably managing some liver cirrhosis-related complications, such as spontaneous bacterial peritonitis (SBP), hepatic encephalopathy (HE), and hepatorenal syndrome. However, its clinical benefits remain controversial.
METHODS
EMBASE, PubMed, and Cochrane Library databases were searched. Randomized controlled trials (RCTs) regarding use of human albumin infusion in cirrhotic patients were eligible. Mortality and incidence of liver cirrhosis-related complications were pooled. Effect of human albumin infusion on mortality was also evaluated by subgroup analyses primarily according to target population and duration of human albumin infusion treatment. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.
RESULTS
Forty-two RCTs were finally included. Meta-analysis showed that human albumin infusion could significantly decrease the mortality of cirrhotic patients (OR = 0.81, 95% CI = 0.67-0.98, p = 0.03). Subgroup analyses showed that human albumin infusion could significantly decrease the mortality of cirrhotic patients with SBP (OR = 0.36, 95% CI = 0.20-0.64, p = 0.0005) and HE (OR = 0.43, 95% CI = 0.22-0.85, p = 0.02), but not those with ascites or non-SBP infections or undergoing large-volume paracentesis. Short-term human albumin infusion treatment could significantly decrease short-term mortality (OR = 0.67, 95% CI = 0.50-0.89, p = 0.005), but not long-term mortality. Long-term human albumin infusion treatment could not significantly decrease long-term mortality (OR = 0.72, 95% CI = 0.48-1.08, p = 0.11). In addition, human albumin infusion could significantly decrease the incidence of renal impairment (OR = 0.63, 95% CI = 0.45-0.88, p = 0.007) and ascites (OR = 0.45, 95% CI = 0.25-0.81, p = 0.007), but not infections or gastrointestinal bleeding.
CONCLUSIONS
Human albumin infusion may improve the outcomes of cirrhotic patients. However, its indications for different complications and infusion strategy in liver cirrhosis should be further explored.

Review
Ascites is the most common complication of liver cirrhosis. Midodrine is a vasoconstrictor that improves splanchnic and systemic hemodynamics, reduces ascites, and improves clinical outcomes. Here, we aimed to examine the role of midodrine in cirrhosis-related ascites. Scopus, Embase, PubMed, and PubMed Central databases were searched for relevant randomized controlled trials comparing midodrine with other interventions in patients with cirrhotic ascites on November 25, 2020, using appropriate keywords like "midodrine", "ascitic cirrhosis", "peritoneal paracentesis" and suitable Boolean operators. Odds ratio (OR) and mean difference (MD) were used to analyze pool data as appropriate with a 95% confident interval (CI). A total of 14 studies were included in our analysis including 1199 patients. The addition of midodrine resulted in statistically significant improvement in mean arterial pressure (MAP) (MD, 3.95 mmHg; 95% CI, 1.53-6.36) and MELD (Model for End-Stage Liver Disease) score (MD, -1.27; 95% CI, -2.49 to -0.04) compared to standard medical treatment (SMT). There was also a significant improvement in plasma renin activity and plasma aldosterone concentration. However, there was no significant improvement in mortality or serum creatinine compared to SMT. In addition, there was no statistically significant improvement in MAP, plasma renin activity, plasma aldosterone concentration, MELD score, overall mortality, and paracentesis-induced circulatory dysfunction comparing midodrine with albumin. Midodrine alone leads to significant improvement in various clinical parameters in patients with cirrhotic ascites compared to standard medical care. At the same time, it was found to be non-inferior to albumin. Therefore, further well-designed studies need to be carried out on midodrine in addition to albumin for optimal clinical benefits among patients with ascites due to cirrhosis.

BACKGROUND
Natriuretic peptides are involved in the cascade of pathophysiological events occurring in liver cirrhosis, counterbalancing vasoconstriction and anti-natriuretic factors. The effects of natriuretic peptides as treatment of cirrhotic ascites have been investigated only in small studies, and definitive results are lacking.
AIM
To examine the effects and safety of natriuretic peptides in cirrhosis patients with ascites.
METHODS
We searched MEDLINE, Web of Science, Scopus, Cochrane Library and Embase for all available studies applying intravenous administration of any natriuretic peptide to patients suffering from cirrhotic ascites. Inclusion was not limited by treatment duration or dose, or by follow-up duration. Both randomised controlled trials and non-randomised studies were eligible for inclusion. The primary outcome was change in renal sodium excretion. Secondary outcomes included safety measures and changes in renal water excretion, plasma aldosterone concentration, and plasma renin activity.
RESULTS
Twenty-two studies were included. Atrial natriuretic peptide (ANP) was the only intensively studied treatment. Sodium excretion increased in response to continuous ANP infusion and was more pronounced when infusion rates of > 30 ng/kg/min were administered compared with ≤ 30 ng/kg/min ( < 0.01). Moreover, natriuresis was significantly higher in study subgroups with mild/moderate ascites compared with moderate/severe and refractory ascites ( < 0.01). ANP infusions increased renal water excretion, although without reaching a statistically significant dose-response gradient. Plasma aldosterone concentration and plasma renin activity were significantly lower at baseline in study subgroups achieving a negative sodium balance in response to an ANP administration compared with treatment non-responders ( < 0.01). Blood pressure decreases occurred less frequently when ANP doses ≤ 30 ng/kg/min were applied. The quality of evidence for a natriuretic response to ANP was low, mainly due to small sample sizes and considerable between-study heterogeneity. Data were sparse for the other natriuretic peptides; B-type natriuretic peptide and urodilatin.
CONCLUSION
Intravenous ANP infusions increase sodium excretion in patients with cirrhotic ascites. Continuous infusion rates > 30 ng/kg/min are the most effective. However, safety increases with infusion rates ≤ 30 ng/kg/min.

Obstetrics and Gynecology Dec 2021To describe the etiology of isolated fetal ascites and associated perinatal outcomes, and to assess the progression of isolated fetal ascites to fetal hydrops.
OBJECTIVE
To describe the etiology of isolated fetal ascites and associated perinatal outcomes, and to assess the progression of isolated fetal ascites to fetal hydrops.
DATA SOURCES
PubMed, Cochrane Library, Scopus, and ClinicalTrials.gov databases were searched using the following keywords: "fetus" OR "foetal" OR "fetal" OR "foetus" AND "ascites" from inception to February 2020. The search was limited to the English language.
METHODS OF STUDY SELECTION
A total of 1,983 articles were identified through the search strategy. All studies containing five or more cases of isolated fetal ascites were included.
TABULATION, INTEGRATION, AND RESULTS
Eleven studies, involving 315 cases of isolated fetal ascites, were eligible for inclusion in this systematic review. All included studies were evaluated using the tool for evaluating the methodologic quality of case reports and case series described by Murad et al. Data were summarized using narrative review and descriptive statistics. Two-tailed Fisher exact P values calculated from hypergeometric distribution were used to compare outcome by etiology. CIs were calculated with Clopper-Pearson exact binomial interval. The etiologies of isolated fetal ascites are genitourinary (24%), gastrointestinal (20%), viral or bacterial infections (9%), cardiac (9%), genetic disorders not otherwise categorized (8%), chylous ascites (6%), metabolic storage disorders (3%), other structural disorders (4%), other causes (4%) and idiopathic (13%). Survival is most favorable for cases of isolated fetal ascites as a result of chylous (100%), idiopathic (90%), gastrointestinal (77%) and genitourinary (77%) etiologies. Survival is least favorable for fetuses with isolated fetal ascites as a result of structural disorders (25%), cardiac etiology (32%) and metabolic storage disorders (33.3%). When pregnancy terminations were excluded, survival rates were similar between fetuses diagnosed at or after 24 weeks of gestation compared with those diagnosed at less than 24 weeks (74% vs 61%, P=.06). Progression of fetal ascites to fetal hydrops occurred in 6.6% (95% CI 3.6-9.6%) (17/259) of cases when pregnancies that were terminated were excluded.
CONCLUSION
Isolated fetal ascites has a diverse etiology. Outcome is related to the etiology of isolated fetal ascites. In the majority of cases, fetal ascites does not progress to fetal hydrops.
