RESUMEN
AIMS: The mortality rate for -COVID-19 infection varies significantly depending on age and comorbidities but remains high in hospitalized patients overall. Several retrospective studies have identified patients with end-stage kidney disease (ESKD) to be at increased risk. The objective of this study was to study in-hospital outcomes of ESKD patients at an academic medical center and identify characteristics that place them at a higher risk for in-hospital mortality. MATERIALS AND METHODS: A retrospective chart review was conducted including adult patients (≥ 18 years old) admitted to Loma Linda Medical Center for COVID-19 infection with a previous diagnosis of ESKD. Patients with prior kidney transplants were excluded. The main outcome of this study was the rate of in-hospital mortality. RESULTS: 21 of the 91 patients died with a mortality rate of 23%. Age, D-dimer > 0.4 µg/mL, ejection fraction less than 50%, and ferritin > 300 ng/mL were predictors for mortality in unadjusted univariate analysis. Adjusted multivariable analysis demonstrated that only an ejection fraction of less than 50% was associated with increased mortality risk. CONCLUSION: Cardiovascular disease is the leading cause of mortality for ESKD patients and also places them at increased risk of mortality in the setting of severe COVID-19 infection.
RESUMEN
Lupus nephritis (LN), a severe complication of systemic lupus erythematosus (SLE), leads to significant kidney inflammation and damage and drastically increases mortality risk. Predominantly impacting women in their reproductive years, LN poses specific risks during pregnancy, including pre-eclampsia, growth restrictions, stillbirth, and preterm delivery, exacerbated by lupus activity, specific antibodies, and pre-existing conditions like hypertension. Effective management of LN during pregnancy is crucial and involves carefully balancing disease control with the safety of the fetus. This includes pre-conception counseling and a multidisciplinary approach among specialists to navigate the complexities LN patients face during pregnancy, such as distinguishing LN flare-ups from pregnancy-induced conditions. This review focuses on exploring the complex dynamics between pregnancy and LN, emphasizing the management difficulties and the heightened risks pregnant women with LN encounter.
RESUMEN
Delayed-release (DR) budesonide received expedited approval from the US Food and Drug Administration (FDA) as a treatment for reducing proteinuria in individuals with primary IgA nephropathy (IgAN) who are at significant risk of disease progression. The approval was based on clinical trials primarily involving patients with an estimated glomerular filtration rate (eGFR) greater than 30 mL/min/1.73 m2. However, the efficacy of DR budesonide in reducing kidney function decline, especially in patients with an eGFR less than 30 mL/min/1.73 m2 and proteinuria less than 1 g/d, remains unclear. We report the case of a 43-year-old man with a long-term history of hypertension and biopsy-proven IgAN who experienced a progressive increase in proteinuria and serum creatinine, along with a decline in eGFR to 28 mL/min/1.73 m2 despite maximal supportive management. Following therapy with DR budesonide, a decreasing trend in proteinuria and a stabilization of eGFR were observed in the recent measurements. While initial data suggested the effectiveness of DR budesonide primarily in patients with an eGFR over 30 mL/min/1.73 m2, our case demonstrates the potential of DR budesonide for use in scenarios beyond its currently approved indications. This underscores the need for additional research on patients with advanced stages of chronic kidney disease.

Calciphylaxis is a rare and severe disease characterized by calcification, fibrosis, and thrombosis of small blood vessels. Although it primarily affects patients with end-stage renal disease (ESRD) on dialysis, limited cases have been reported of calciphylaxis in patients with acute kidney injury (AKI) and lupus. This case report describes the occurrence of calciphylaxis in a 35-year-old female recently diagnosed with lupus nephritis class IV and AKI requiring dialysis.
