AI Article Synopsis
- Preeclampsia affects 3-5% of pregnancies and can pose serious risks to both the parent and child, influenced by various socioeconomic and racial factors in the U.S.
- A study of over 16 million pregnant patients from 2015 to 2019 revealed that those with chronic kidney disease faced a significantly higher risk of developing mild to severe preeclampsia, regardless of the disease stage.
- The research found notable regional disparities in kidney disease severity, with the Northeast reporting milder cases compared to the South and West, and identified higher incidences of eclampsia and mortality among Black and Latinx patients, although socioeconomic status did not correlate with kidney disease rates.
Article Abstract
Background: Preeclampsia occurs in 3% to 5% of pregnancies and can lead to potentially fatal outcomes for parent and child. Disparities in socioeconomic status, medical access, racial or ethnic, and regional background within the United States result in a very heterogenic population.
Objective: We aimed to assess the regional differences in the severity of chronic kidney disease in pregnant patients as well as the risk of preeclampsia in a contemporary cohort within the United States.
Study Design: Pregnant patients were identified within the National Inpatient Sample database between 2015 and 2019. Patients were stratified by diagnosis of end-stage kidney disease or chronic kidney disease. The primary endpoint of this study was to determine the incidence of mild preeclampsia, severe preeclampsia, and eclampsia in hospitalized pregnant patients with kidney dysfunction compared with controls. Secondary endpoints were to determine regional, racial or ethnic, and socioeconomic differences within the United States.
Results: A total of 16,343,563 pregnant patients were identified from 2015 to 2019. Presence of chronic kidney disease increased risk of mild and severe preeclampsia independent of the stage of chronic kidney disease (odds ratio >2 each). There was a markedly difference in prevalence of chronic kidney disease in regard to geographic location within the United States, with patients in the Northeast having predominantly milder stages of chronic kidney disease and patients in the South and West having more progressive kidney disease. There was a significant difference in chronic kidney disease distribution in relation to racial/ethnic background within the United States. Black and Latinx patients were at increased risk of eclampsia and death. There was no significant difference regarding chronic kidney disease and socioeconomic background. However, a larger proportion of patients with very low income had advanced stages of chronic kidney disease.
Conclusion: Our data add to the previous findings that patients with chronic kidney disease are at increased risk of developing preeclampsia even in the modern era of medical management, independent of the cause of chronic kidney disease. Racial or ethnic and geographic differences in chronic kidney disease prevalence exist. A multidisciplinary team approach to follow-up with pregnant patients with chronic kidney disease could decrease maternal and neonatal mortality.

Chronic kidney disease (CKD) is one of the leading health problems in the world. It is silent in the early stages and gradually progresses, inducing renal physiological and structural alterations. Moreover, CKD is associated with impaired life quality, increased risk for cardiovascular diseases, and reduced life expectancy.

Introduction: Lower estimated glomerular filtration rate (eGFR) in patients who have chronic kidney disease (CKD) is associated with increased risk of complications following total knee arthroplasty (TKA). However, there is a lack of literature that identifies eGFR levels those are associated with notable differences in risk of these complications. The purpose of this study was to create eGFR strata for CKD patients that are associated with varying risks of 90-day major complications following TKA.

Renal osteodystrophy is commonly seen in patients with chronic kidney disease (CKD) due to disrupted mineral homeostasis. Given the impaired renal function in these patients, common anti-resorptive agents, including bisphosphonates, must be used with caution or even contraindicated. Therefore, an alternative therapy without renal burden to combat renal osteodystrophy is urgently needed.

Background: Arteriovenous (AV) fistulas are the preferred access for dialysis but have a high incidence of failure. This study aims to understand the crosstalk between skeletal muscle catabolism and AV fistula maturation failure.
Methods: Skeletal muscle metabolism and AV fistula maturation were evaluated in mice with chronic kidney disease (CKD).

Background: In an Italian cohort of lupus podocytopathy patients, we aimed to characterize the presenting features, therapy, and outcomes, and explore differences between relapsing and non-relapsing patients.
Methods: We identified 29 patients with lupus podocytopathy from 1994 to 2023 in 11 Italian Nephrology/Rheumatology Units, and divided them into two groups: relapsing and non-relapsing. Given the limited sample size, a p-value ≤ 0.
