Upper Gastrointestinal Endoscopic Findings In Chronic Kidney Disease And Haemodialyzed Patients In Assiut University Hospitals

Chronic Kidney disease (CKD) is Kidney damage for ≥3 months, as defined by structural &or functional abnormalities of the kidney, with or without decreased GFR or GFR <60 mL/min/1.73m2 for ≥3 months, with or without kidney damage.

Stage Description GFR (ml/min/1.73 m2) Stage I Kidney damage >90 with normal or ↑ GFR Stage II Kidney damage with 60-89 mild ↓ in GFR Stage III Moderate ↓ in GFR 30-59 Stage IV Severe ↓ in GFR 15-29 Stage V Kidney failure < 15 < 15 (or dialysis) Or on dialysis

• CKD virtually affect the functions of all systems in our human body and associated with several deleterious effects on different systems which is due to multiple risk factors and associated with several abnormalities in the gastrointestinal tract involving all its segments, which include : Esophagitis: is present in more than a the third of the third of cases of uremic patients. It is due to increase of intra-abdominal pressure and reflux. The treatment of these patients is not different from that given to the general population with proton pump inhibitors, once the endoscopic study has been done.

Gastritis and peptic ulcer:as In patients with CKD and haemodialyzed patients, serum levels of gastrin are increased due to increased its secretion and decrease its excretion as it is eliminated by the kidney; additionally, cholecystokinin and secretin may be elevated. Noninvasive tests (H. pylori) have lower sensitivity in CKD so upper endscopy is needed.

In CKD and ESRD patients have more symptoms than general population.Specifically, gastrointestinal distress symptoms and peptic ulcers . The recurrence of peptic ulcer disease (PUD) after Helicobacter pylori eradication is higher in uremic patients than in non-uremic patients, and patients with ESRD have higher complication rates after ulcer development . Therefore, upper endoscopy should be performed in patients with these risk factors more often to prevent severe complications, such as gastrointestinal bleeding ( Haematemesis and melena). Angiodysplasia: affects the microcirculation of the mucosa and sub mucosa of the entire gastrointestinal tract. It is a frequent cause of bleeding in elderly patients, and its incidence is increased in patients on dialysis. Which diagnosed mainly by upper endoscopy as well as for the treatment with hemostasis techniques. The other option is angiography embolization, .
