A basic solution for a complex problem: does treatment of metabolic acidosis slow CKD progression?

PURPOSE OF THIS REVIEW: Metabolic acidosis is frequently encountered in patients with chronic kidney disease (CKD), with increasing prevalence as kidney function worsens. Treating electrolyte disturbances is the sine qua non of Nephrologists, and alkali therapy to normalize serum bicarbonate levels and slow progression of kidney disease has been embedded in clinical practice guidelines for decades on the basis of animal models and controversial clinical trials. This review will critically appraise the literature base for this recommendation and determine whether the available evidence supports this common practice, which is a timely endeavor considering the impending demotion of metabolic acidosis treatment from recommendation to practice point in forthcoming KDIGO guidelines. RECENT FINDINGS: Earlier, open-label, studies supporting the utility of sodium bicarbonate therapy to slow progression of chronic kidney disease have been challenged by more recent, blinded, studies failing to show benefit on CKD progression. This was further demonstrated in the absence of concomitant sodium administration with the hydrochloric acid binder veverimer, which failed to demonstrate benefit on renal death, end stage kidney disease or 40% reduction in estimated glomerular filtration rate in a large multicenter trial. SUMMARY: The current body of literature does not support the routine treatment of metabolic acidosis in patients with CKD and the authors agree with the forthcoming KDIGO guidelines to de-emphasize this common practice.

Treatment of hypokalemia with amiloride unmasked hypercalcemia and hyperparathyroidism: A case report.

Colonic pseudo-obstruction, also called Ogilvie's syndrome, occurs due to impaired intestinal propulsion, and may be caused by electrolyte imbalances such as hypokalemia and some endocrine disorders such as hyperparathyroidism. Secretory diarrhea due to intestinal pseudo-obstruction can cause hypokalemia. Diuretics such as amiloride can be used to treat hypokalemia, however in this case, treatment with amiloride induced hypercalcemia and unmasked hyperparathyroidism. A 73-year-old female with a history of hypertension and parathyroid adenoma presented with recurrent colonic pseudo-obstruction and chronic hypokalemia. Her hypokalemia was treated with amiloride, causing hypercalcemia of 14.4 mg/dL, elevated PTH, and altered mental status. Amiloride was subsequently discontinued with improvement in her symptoms, and her hyperparathyroidism was treated with cinacalcet. To our knowledge, this is the first report of amiloride unmasking hyperparathyroidism and inducing hypercalcemia.

"I'm Not Good with Money" and Other Lies Residents Tell Themselves about Personal Finance.

OBJECTIVES: Some physicians believe that they have difficulty managing their own personal finances, and many medical schools and residences do not have formal financial curricula embedded in education. Given that many medical students have >$200,000 in school loans, physicians are expected to navigate the complex financial world without guidance. METHODS: In this article, the authors developed a personal finance curriculum for Internal Medicine residents with the aim of evaluating the proportion of residents engaging in active personal finance activities, increasing their knowledge of financial literacy and their comfort with personal finance concepts using a pre- and postintervention survey. The content of the curriculum included four modules structured around different financial themes and delivered to trainees in 45-minute sessions. RESULTS: A majority of the residents were able to participate in workplace retirement, log into their retirement account, possessed a Roth individual retirement account, manage a budget, and check their credit score. An area prompting concern postintervention was the level of discomfort engaging with personal finance that disproportionally affected the female trainees more than their male counterparts. CONCLUSIONS: It is likely that an individual's comfort level managing finances stems from money beliefs, rather than actual ability given the requirements to graduate from medical school and the demands of an Internal Medicine residency.

Concomitant Lung and Kidney Disorders in Critically Ill Patients: Core Curriculum 2022.

The lungs and kidneys are cooperative and interdependent organs that secure the homeostasis of the body. Volume and acid-base disorders sit at the nexus between these two systems. However, lung-kidney interactions affect the management of many other conditions, especially among critically ill patients. Therefore, management of one system cannot proceed without a thorough understanding of the physiology of the other. This installment of AJKD's Core Curriculum in Nephrology discusses the complex decision-making required in treating concomitant respiratory and kidney disorders. We cover systemic diseases of the pulmonary and glomerular capillaries, acute decompensated heart failure, management of acid-base disorders in acute respiratory distress syndrome and chronic obstructive pulmonary disease, and venous thromboembolism. Through a case-based approach, we weigh the factors affecting the risks and benefits of therapies to enable the reader to individualize treatment decisions in these challenging scenarios.

Person-Centered Care for Older Adults With Kidney Disease: Core Curriculum 2019.

This Core Curriculum article models a person-centered approach to care for older adults with kidney disease. We provide background information on the principles of person-centered care and outline ways in which this approach contrasts with the more disease-based approaches that dominate current medical education and practice. Using hypothetical cases, we discuss 3 clinical scenarios that arise commonly when caring for older adults with kidney disease: (1) a moderate reduction in estimated glomerular filtration rate, (2) new-onset nephrotic-range proteinuria, and (3) the prospect of starting dialysis. For each scenario, we summarize relevant available evidence and model what a person-centered approach might look like. In discussing each scenario, we highlight: (1) the considerable heterogeneity in clinical presentation, circumstances, priorities, and values that exist among older adults with kidney disease; (2) the importance of interpreting available evidence and clinical practice guidelines in the context of what is relevant to each patient; (3) methods for grounding discussions about care and treatment options in the realities of each patient's situation and what is most meaningful to them; and (4) the importance of setting aside one's own biases and practice style to ensure that patients' own values and goals guide their care.
