Treatment of pediatric hyperkalemia with sodium polystyrene sulfonate

Hyperkalemia in Pediatric Severe Malaria

Severe malaria remains an important global cause of mortality, particularly in sub-Saharan Africa, where the majority of deaths occur in children under 5 years of age. Hyperkalemia in severe malaria has not been very well reported but is associated with increased mortality. Severe malaria has several features that predispose patients to hyperkalemia, including acute kidney injury, hemolysis, metabolic acidosis, and severe anemia requiring blood transfusion. Our objective is to discuss the epidemiology of hyperkalemia in severe malaria, provide an overview of potassium homeostasis, and discuss risk factors for elevated potassium levels in severe malaria, as well as management strategies considering the resource-limited settings where malaria is endemic.

Orally administered fluorescent nanosized polystyrene particles affect cell viability, hormonal and inflammatory profile, and behavior in treated mice

Commercially manufactured or generated through environmental degradation, microplastics (MPs) and nanoplastics (NPs) considerably contribute to environmental pollution. There is a knowledge gap in how exposure to MPs/NPs changes cellular function and affects animal and human health. Here, we demonstrate that after oral uptake, fluorescent polystyrene (PS) nanoparticles pass through the mouse digestive system, accumulate and aggregate in different organs, and induce functional changes in cells and organs. Using cochlear explant as a novel in vitro system, we confirmed the consequences of PS-MP/NP interaction with inner ear cells by detecting aggregates and hetero-aggregates of PS particles in hair cells. The testes of treated males accumulated MPs/NPs in the interstitial compartment surrounding the seminiferous tubules, which was associated with a statistically significant decrease in testosterone levels. Male mice showed increased secretion of interleukins (IL-12p35 and IL-23) by splenocytes while cyto- and genotoxicity tests indicated impaired cell viability and increased DNA damage in spleen tissue. Males also showed a broad range of anxiogenic responses to PS nanoparticles while hippocampal samples from treated females showed an increased expression of Bax and Nlrp3 genes, indicating a pro-apoptotic/proinflammatory effect of PS treatment. Taken together, induced PS effects are also gender-dependent, and therefore, strongly motivate future research to mitigate the deleterious effects of nanosized plastic particles.

Nebulized salbutamol diminish the blood glucose fluctuation in the treatment of non-oliguric hyperkalemia of premature infants

BACKGROUND

Hyperkalemia is a risky and potentially life-threatening condition in pre-term infants. Glucose-insulin infusion has been considered a major therapeutic way for non-oligouric hyperkalemia but affects the stability of blood sugar level. We aimed to evaluate the effectiveness of salbutamol nebulization compared to glucose-insulin infusion for the treatment of non-oliguric hyperkalemia in premature infants.

METHODS

Forty premature infants (gestation age ≤36 weeks) with non-oliguric hyperkalemia (central serum potassium level greater than 6.0 mmol/L) within 72 h of birth were enrolled in this study. These infants were randomly assigned into two groups. One group received a regular insulin bolus with glucose infusion (Group A; n = 20), and the other received salbutamol (Ventolin) by nebulization (Group B; n = 20). Potassium level, blood sugar, heart rate, and blood pressure were recorded for each group before treatment and at 3, 12, 24, 48, and 72 h post-treatment.

RESULTS

The serum potassium levels were reduced after treatment in both groups. No significant changes in heart rate or blood pressure were observed in either group. The fluctuation in glucose levels was gentler in the salbutamol-treated group than in the glucose-insulin infusion group.

CONCLUSION

Salbutamol nebulization is not only as effective as glucose-insulin infusion for treating non-oliguric hyperkalemia in premature infants but can avoid potential side effects such as vigorous blood glucose fluctuations.

Pharmacological management of acute kidney injury and chronic kidney disease in neonates

Both acute kidney injury (AKI) and chronic kidney disease (CKD) are seen more frequently in the neonatal intensive care unit (NICU) as advances in supportive care improve the survival of critically ill infants as well as those with severe, congenital kidney and urinary tract anomalies. Many aspects of the infant's care, including fluid balance, electrolyte and mineral homeostasis, acid-base balance, and growth and nutrition require close monitoring by and collaboration among neonatologists, nephrologists, dieticians, and pharmacologists. This educational review summarizes the therapies widely used for neonates with AKI and CKD. Use of these therapies is extrapolated from data in older children and adults or based on clinical experience and case series. There is a critical need for more research on the use of therapies in infants with kidney disease as well as for the development of drug delivery systems and preparations scaled more appropriately for these small patients.
