Detailed Description

Biliary tract disorders including cholelithiasis, cholecystitis, and other diseases of the biliary tract, are one of the most prevalent medical issues in the digestive system, posing a myriad of challenges for health workers and patients. Gallbladder dysfunction is the most frequent cause of symptomatic and complicated biliary tract disorders. Although gallbladder dysfunction is a common condition in Middle East countries, data on the incidence of end-stage renal disease (ESRD) are limited. The occurrence of gallbladder dysfunction in patients fed with low-protein diets suggests that gallbladder stones formation is affected by dietary protein content. Also the lithogenic composition changes of bile, increased nucleation tendency, and impaired motility of gallbladder are important factors in ESRD patients. It has been reported that chronic kidney disease (CKD) patients on regular hemodialysis (HD) have increased bile cholesterol levels and an increased bile saturation index. In addition, the gallbladder is innervated by the autonomic nervous system, which malfunctions in uremia, and it has been shown that gallbladder stasis might cause increased stone formation. In some studies, the prevalence of gallbladder dysfunction has been shown to increase in patients undergoing hemodialysis (HD) treatment for ESRD. So, we focused in this study to try to find association of gallbladder dysfunction in pre-dialysis ESRD and HD patient in comparison to normal renal function individuals.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

individuals visiting outpatient clinics of nephrology, GIT and internal medicine in Assiut hospitals.

Description

Inclusion Criteria:

  • Patients who are diagnosed as CKD with eGFR according to Cockcroft-Gault Equation, whatever they are on regular hemodialysis or pre-dialysis without history of previous gallbladder dysfunction with normal renal function individuals.

Exclusion Criteria:

  • Patients who are younger than 18 years.
  • Patients who are diabetic.
  • Patients who have body mass index (BMI) more than 30.
  • Patients who have family history of gallbladder disorder.

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.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Group I
Gallbladder dysfunction in pre-dialysis CKD patients.
Diagnostic test: abdominal ultrasonography.
Evaluate the gallbladder ejection fraction (EF)
Group II
Gallbladder dysfunction in end stage CKD patients on dialysis.
Diagnostic test: abdominal ultrasonography.
Evaluate the gallbladder ejection fraction (EF)
Control Group
Gallbladder dysfunction in normal renal function participants (control group).
Diagnostic test: abdominal ultrasonography.

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
Gallbladder dysfunction in CKD patients
Time Frame: measuring fasting gallbladder volume (FV) after 10 overnight hours fasting and the residual gallbladder volume (RV) after 30 minutes after standard fixed meal
Evaluate the gallbladder ejection fraction (EF) which will be calculated by following formula. (EF = (fasting gallbladder volume (FV) - residual gallbladder volume (RV)) / fasting gallbladder volume (FV)x 100) EF = (FV - RV) / FV x 100
measuring fasting gallbladder volume (FV) after 10 overnight hours fasting and the residual gallbladder volume (RV) after 30 minutes after standard fixed meal

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 (Estimated)

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.
June 1, 2024

Primary Completion (Estimated)

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.
