Background: Patients with end-stage kidney disease (ESKD) on maintenance dialysis have a high risk of developing hyperkalemia. In addition to traditional approaches, a new option for the management of patients on dialysis includes the use of a potassium binder, sodium zirconium cyclosilicate (SZC). We evaluated the effect and safety of SZC in patients with chronic PD. Objective: To present a case series that illustrates the real-world use of new potassium-binders in hyperkalemic patients on peritoneal dialysis. Methods: This case series collected 9 patients on PD with baseline potassium values > 5.5 mmol/l and who were treated with SZC 5 g once a day. Data were collected at baseline and at 1, 2, and 3 months after initiation of treatment. Results: The median age of patients was 64.5 years and the median duration of observation was 90 ± 5 days. It was observed that median serum potassium decreased (5.8 mmol/l at baseline with a range of 5.8 mmol/L - 6.8 mmol/L versus 4.5 in the third month with a range of 3.6 mmol/L - 5.3 mmol/L) after SZC treatment. Adverse events were observed in 2 (22.2%). The unique adverse event was constipation and presented in 2 patients (22.2%). Constipation was mild and transient during the observation period. No adverse events of special interest were reported. Conclusion: Normokalemia was established and maintained in this series of patients treated with SZC. No episodes of hyper- or hypo-kalemia were observed. SCZ had a good safety profile and was well tolerated over 3 months.

Successful Treatment of Peritoneal dialysis Related Peritonitis from Multi-Drug Resistant Sphingomonas paucimobilis with Combination Therapy: A Case Report

引用

Open Journal of Nephrology 2022年第2期12卷 228-234页

作者： Gennaro Argentino Silvio Borrelli Ciro Paglionico Andrea Camocardi Mario Iorio Alessandra Antonia Mele Andrea Pota Adelia Sagliocca Stefania Brancaccio lucia di micco “Ospedale del Mare” Nephrology and Dialysis Unit ASL Napoli 1 Centro Naples Italy Nephrology and dialysis Unit University of Studies of Campania “Luigi Vanvitelli” Naples Italy

Sphingomonas paucimobilis is an emerging gram-negative aerobic bacterium, generally causing infections in immunocompromised patients. Few data are available about peritonitis in peritoneal dialysis due to this pathogen. The clinical courses and outcomes of peritonitis are variable, with a high frequency of catheter removal and peritoneal dialysis withdrawal. No guidelines are available for the treatment of Sphingomonas paucimobilis related peritonitis, due to its emerging role as pathogen, the high antibiotic resistance and unpredictable antibiotic sensitivity. Here, we describe a case of Sphingomonas paucimobilis peritonitis in a 52-year-old diabetic patient in Continuous Cycler-Assisted Peritoneal dialysis (CCPD) for 4 months, successfully treated with a combined intraperitoneally administration of meropenem (250 mg/L) and ciprofloxacin (100 mg/L) for 21 days. No hospital admission and change of peritoneal dialysis scheme were needed;no relapses of peritonitis were observed during 18 months of follow-up.

Therapeutic implications of colon cancer stem cells

Colorectal cancer is the second most common cause of cancer-related death in many industrialized countries and is characterized by a heterogenic pool of cells with distinct differentiation patterns. Recently, the concept that cancer might arise from a rare population of cells with stem cell-like properties has received support with regard to several solid tumors, including colorectal cancer. According to the cancer stem cell hypothesis, cancer can be considered a disease in which mutations either convert normal stem cells into aberrant counterparts or cause a more differentiated cell to revert toward a stem cell-like behaviour; either way these cells are thought to be responsible for tumor generation and propagation. The statement that only a subset of cells drives tumor formation has major implications for the development of new targeted therapeutic strategies aimed at eradicating the tumor stem cell population. This review will focus on the biology of normal and malignant colonic stem cells, which might contribute to our understanding of the mechanisms responsible for tumor development and resistance to therapy.

Neurotrophins are a family of proteins that support neuronal proliferation, survival, and differentiation in the central and peripheral nervous systems, and are regulators of neuronal plasticity. Nerve growth factor is one of the best-described neurotrophins and has advanced to clinical trials for treatment of ocular and brain diseases due to its trophic and regenerative properties. Prior trials over the past few decades have produced conflicting results, which have principally been ascribed to adverse effects of systemic nerve growth factor administration, together with poor penetrance of the blood-brain barrier that impairs drug delivery. Contrastingly, recent studies have revealed that topical ocular and intranasal nerve growth factor administration are safe and effective, suggesting that topical nerve growth factor delivery is a potential alternative to both systemic and invasive intracerebral delivery. The therapeutic effects of local nerve growth factor delivery have been extensively investigated for different ophthalmic diseases, including neurotrophic keratitis, glaucoma, retinitis pigmentosa, and dry eye disease. Further, promising pharmacologic effects were reported in an optic glioma model, which indicated that topically administered nerve growth factor diffused far beyond where it was topically applied. These findings support the therapeutic potential of delivering topical nerve growth factor preparations intranasally for acquired and degenerative brain disorders. Preliminary clinical findings in both traumatic and non-traumatic acquired brain injuries are encouraging, especially in pediatric patients, and clinical trials are ongoing. The present review will focus on the therapeutic effects of both ocular and intranasal nerve growth factor delivery for diseases of the brain and eye.
