Summary
Sodium polystyrene sulphonate (SPS), used for hyperkalemia, can cause colonic necrosis, even with low sorbitol. Physicians should consider safer alternatives to manage high potassium levels.
Area of Science:
- Nephrology
- Gastroenterology
- Internal Medicine
Background:
- Sodium polystyrene sulphonate (SPS) is a potassium-binding resin used to treat hyperkalemia.
- It is often co-administered with sorbitol to prevent gastrointestinal complications.
- Kayexalate is a common formulation of SPS.
Observation:
- A case of colonic necrosis occurred in a patient treated with Kayexalate.
- This severe complication arose despite the presence of minimal sorbitol.
- The patient's hyperkalemia was being managed with Kayexalate.
Findings:
- Kayexalate administration, even with low sorbitol, poses a risk of colonic necrosis.
- This adverse event highlights a serious complication of SPS therapy.
- The efficacy of SPS in reducing potassium levels is overshadowed by this potential risk.
Implications:
- Physicians must exercise caution when prescribing Kayexalate for hyperkalemia.
- Alternative medications for potassium reduction with a better safety profile should be considered.
- Awareness of Kayexalate-induced colonic necrosis is crucial for patient safety.

01:14Prevention of Further Absorption of Poison
818
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:29Drugs for Treatment of Ulcerative Colitis in IBD
138
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...
