Original Abstract of the Article

Major research findings

Sodium polystyrene sulfonate (PSS) is a medication commonly used to treat hyperkalemia. 23 found that administering PSS to lower the potassium concentration in milk delayed the introduction of peritoneal dialysis in a 1-month-old infant with milk allergy. 18 reviewed the efficacy and safety of PSS in treating patients with chronic kidney disease (CKD) and hyperkalemia. 2 conducted a systematic review and meta-analysis to evaluate the association between PSS usage and the risk of intestinal necrosis. 5 reported the potential digestive complications associated with PSS in dialysis patients. 4 investigated the effect of PSS on reducing potassium content in food. examined the clinical effects and side reactions of PSS in treating hyperkalemia associated with renal insufficiency. 17 conducted a case study to understand the influence of salts and sugars on the interaction between bovine serum albumin and PSS. 6 explored the antiplaque effect of PSS in a clinical study. 15 compared a single dose of SZC (Sodium zirconium cyclosilicate) with PSS in hospitalized patients with hyperkalemia. 25 discussed the mechanism, clinical significance, and management of hyperkalemia induced by RAAS (Renin-angiotensin-aldosterone system) inhibitors. 8 assessed the efficacy of single-dose SZC compared to PSS in managing asymptomatic hyperkalemia in hospitalized patients. 20 evaluated the effectiveness and safety of potassium-lowering regimens, including PSS, in treating acute hyperkalemia in hemodialysis patients. 21 conducted an in vitro evaluation of a pH-sensitive hydrogel for controlled drug delivery using PSS. 16 compared the efficacy of patiromer and PSS in reducing potassium levels in chronic hemodialysis patients. 1 compared the effects of calcium and sodium polystyrene sulfonate on mineral and bone metabolism in patients with hyperkalemia. 10 evaluated the efficacy of orally administered montmorillonite in a rat model of myoglobinuric acute renal failure. 24 presented a unique case report of gastric pneumatosis as a rare side effect of PSS. 7 examined the effect of PSS treatment on serum potassium concentrations in mice with lithium toxicity. 12 compared SZC to PSS for the inpatient management of acute hyperkalemia. 11 compared the effectiveness and safety of PSS and SZC for hyperkalemia treatment in hospitalized patients. 1 compared the effects of calcium and PSS on mineral and bone metabolism in patients with hyperkalemia. 19 discussed the role of potassium binders, including PSS, in optimizing therapies for heart failure. 9 reviewed strategies for understanding and treating hypertension and hyperkalemia in CKD patients. 14 reviewed potassium disorders, including hypokalemia and hyperkalemia.

Benefits and Risks

Benefit Summary

PSS has been shown to be effective in treating hyperkalemia. 23 found that administering PSS to lower the potassium concentration in milk delayed the introduction of peritoneal dialysis in a 1-month-old infant with milk allergy. 18 reviewed the efficacy and safety of PSS in treating patients with chronic kidney disease (CKD) and hyperkalemia. 25 discussed the mechanism, clinical significance, and management of hyperkalemia induced by RAAS (Renin-angiotensin-aldosterone system) inhibitors. 19 discussed the role of potassium binders, including PSS, in optimizing therapies for heart failure. 9 reviewed strategies for understanding and treating hypertension and hyperkalemia in CKD patients.

Risk Summary

PSS has the potential to cause gastrointestinal side effects. 2 conducted a systematic review and meta-analysis to evaluate the association between PSS usage and the risk of intestinal necrosis. 5 reported the potential digestive complications associated with PSS in dialysis patients. 24 presented a unique case report of gastric pneumatosis as a rare side effect of PSS.

Comparison of Studies

Commonalities among Studies

Many studies have demonstrated the effectiveness of PSS in treating hyperkalemia. They also consistently mention the possibility of gastrointestinal side effects.

Differences among Studies

There are variations in the efficacy and severity of side effects reported in different studies. 23 found that administering PSS to lower the potassium concentration in milk delayed the introduction of peritoneal dialysis in a 1-month-old infant with milk allergy. 18 reviewed the efficacy and safety of PSS in treating patients with chronic kidney disease (CKD) and hyperkalemia. 25 discussed the mechanism, clinical significance, and management of hyperkalemia induced by RAAS (Renin-angiotensin-aldosterone system) inhibitors. 19 discussed the role of potassium binders, including PSS, in optimizing therapies for heart failure. 9 reviewed strategies for understanding and treating hypertension and hyperkalemia in CKD patients.

Consistency and Discrepancies in Results

Several studies consistently indicate that PSS is effective in treating hyperkalemia. However, the possibility of gastrointestinal side effects is also consistently mentioned, and the extent of these effects varies across studies.

Considerations for Real-Life Applications

PSS is an effective medication for treating hyperkalemia, but it's crucial to use it under the guidance of a healthcare professional due to the potential for gastrointestinal side effects. Additionally, individuals with hyperkalemia should be mindful of their diet and seek dietary guidance as PSS can reduce the amount of potassium in food.

Limitations of Current Research

Despite extensive research on PSS, further investigation is still necessary. Specifically, further research is required to understand the mechanisms underlying PSS-induced gastrointestinal side effects and explore ways to mitigate these side effects.

Future Directions for Research

Future research on PSS should focus on more detailed analysis of its efficacy and safety. Furthermore, elucidating the mechanisms behind PSS-induced gastrointestinal side effects and developing strategies to minimize these side effects are crucial.

Conclusion

PSS is an effective medication for treating hyperkalemia, but it's crucial to use it under the guidance of a healthcare professional due to the potential for gastrointestinal side effects. Further research is needed to improve our understanding of PSS's efficacy and safety. It's important to consult with your healthcare provider if you have hyperkalemia to determine the best course of treatment for your individual needs.
