Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Based on clinical diagnosis, SBP is commonly underdiagnosed because of its nonspecific or asymptomatic presentation. Therefore, a diagnostic paracentesis should be performed in all cirrhotic patients with ascites who require emergency room care or hospitalization, who demonstrate signs/symptoms suggesting SBP, or who present gastrointestinal bleeding, in order to exclude SBP. Several non-invasive methods were tried in many studies for SBP diagnosis, as alternatives to diagnostic paracentesis, e.g., fecal calprotectin. Moreover, numerous scores were proposed for SBP diagnosis with variable accuracies, such as procalcitonin, ESR, and CRP (PEC) index, the modified Wehmeyer SBP scoring system, and Mansoura scoring system. This study aims at evaluating the diagnostic accuracy of serum procalcitonin, PEC index, modified Wehmeyer, and Mansoura scoring systems for SBP in cirrhotic patients with ascites. participants will be subjected to: Clinical evaluation: medical history and physical examination, Routine Laboratory investigations, Serum procalcitonin, Ascitic fluid study, Ascitic fluid culture with antibiotic sensitivity, Abdominal ultrasonography. The following scores will be calculated: Modified Child Pugh score, MELD score, MELD Na score, PEC index, Modified Wehmeyer score, and Mansoura score.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
SBP group
Patients diagnosed as spontaneous bacterial peritonitis based on ascitic fluid study.
non-SBP group
Patients without spontaneous bacterial peritonitis based on ascitic fluid study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PEC index
Time Frame: five months
procalcitoin × (ESR + CRP)
five months
Modified Wehmeyer score
Time Frame: five months
a score is calculated based on age, CRP level, and platelet count using a scale from 0 to 5 as follows: age >60 years: 1 point. platelet count <100,000/mL: 1 point CRP between 13.5 and30 mg/L: 1 point CRP between 30 and 60 mg/L: 2 points CRP above 60 mg/L: 3 points
five months
Mansoura score
Time Frame: five months
score is calculated based on age, mean platelets volume, neutrophil lymphocytic ratio, and CRP using a scale of 0 to 5 as follows: Age ≥55 years: 1 point MPV ≥8.5 fl: 1 point NLR≥2.5: 1 point CRP≥40 mg/l: 2 points
five months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 15, 2023

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
