Chronic Kidney Disease Stage and Cardiovascular and Mortality Events Among Older Adults: The SPRINT Trial.

Rationale & Objective: The risk implications of the Kidney Disease: Improving Global Outcomes (KDIGO) chronic kidney disease classification in older adults are controversial. We evaluated the risk of adverse outcomes in this population across categories of estimated glomerular filtration rate (eGFR) and urinary albumin-creatinine ratio (UACR). Study Design: Prospective cohort. Settings & Participants: In total, 2,509 participants aged ≥75 years in the Systolic Blood Pressure Intervention Trial (SPRINT). Exposure: KDIGO eGFR and UACR categories. We combined KDIGO categories G1 and G2, G3b and G4, as well as A2 and A3. Outcomes: Primary SPRINT outcome (composite of myocardial infarction, other acute coronary syndromes, stroke, heart failure, or death from cardiovascular causes), and all-cause death. Analytical Approach: Multivariable Cox proportional hazard models. Results: Mean age was 79.8 years, and 37.4% were female. The mean eGFR was 64.0 mL/min/1.73 m2, and the median UACR was 13.1 mg/g. In multivariable Cox proportional hazard analysis, compared with participants with eGFR ≥ 60 mL/min/1.73 m2 and UACR < 30 mg/g, there was no statistically significant difference in the risk of the primary outcome among participants with eGFR 45-59 or 15-44 mL/min/1.73 m2 and UACR < 30 mg/g. However, those with eGFR 45-59 or 15-44 mL/min/1.73 m2 and UACR ≥ 30 mg/g had higher risk of the primary outcome (HR [95% CI], 1.97 [1.27-3.04] and 3.32 [2.23-4.93], respectively). The risk for all-cause death was higher for each category of abnormal eGFR and UACR, with the highest risk observed among those with eGFR 15-44 mL/min/1.73 m2 and UACR ≥ 30 mg/g (3.34 [2.05-5.44]). Limitations: Individuals with diabetes and urine protein >1 g/day were excluded from SPRINT. Conclusion: Among older adults SPRINT participants, low eGFR without albuminuria was associated with higher mortality but not with increased risk of cardiovascular events. Additional studies are needed to evaluate an adapted chronic kidney disease stage-based risk stratification for older adults.

Using data from participants in the SPRINT trial, we evaluated the association of chronic kidney disease stage with adverse clinical outcomes among adults older than 75 years without diabetes. We found that low level of kidney function determined by a low estimated glomerular filtration rate with moderately or severely increased urine albumin excretion was associated with increased risk for cardiovascular events and all-cause mortality. However, low estimated glomerular filtration rate with normal or mildly increased urinary albumin excretion was not consistently associated with these adverse outcomes. This finding supports the need for additional studies to evaluate an age-adapted classification of chronic kidney disease to improve risk stratification among older adults.

Cardiac Magnetic Resonance Imaging Used to Determine a Rare Etiology of a Layered Left Ventricular Apical Thrombus.

Eosinophilic myocarditis (EM) is a rare disease, often associated with hypereosinophilic syndrome (HES). Historically, the diagnostic gold standard was endomyocardial biopsy (EMB). We present a unique case of a 58-year-old female who presents after a syncopal episode and was found to have a layered left ventricular (LV) thrombus. Using laboratory studies and cardiac magnetic resonance imaging (MRI), we were able to delineate the etiology, avoiding any invasive testing.

Progression of a Rare Disease, Takayasu Arteritis, With Hematologic and Gastrointestinal Manifestations: A Four-Year Follow-Up Study.

Takayasu arteritis (TA) is a heterogeneous disease whose presentation and progression have not yet been well described. An elderly female was diagnosed with TA after presenting with bilateral arm claudication, elevated ESR, and bilateral subclavian arterial stenosis. In the first two years after diagnosis, she was diagnosed with monoclonal gammopathy of undetermined significance and alpha thalassemia minor. For the next two years, she presented with a non-ST elevation myocardial infarction, three oozing Dieulafoy lesions, and eosinophilic esophagitis. As we observed, TA can have an unusual and unpredictable progression. Therefore, a multidisciplinary approach and clinical surveillance are paramount.

Willingness to receive COVID-19 vaccination in people living with HIV/AIDS from Latin America.

BACKGROUND: Prior research has established some risk factors for an increased risk of severe disease and mortality from coronavirus disease 2019 (COVID-19). However, the impact of HIV infection on SARS-CoV-2 susceptibility and severity is a significant gap in the literature. In the same way, not many studies across the globe have analyzed the degree of vaccination willingness among people living with HIV/AIDS (PLWHA) and considerations regarding prioritizing this population during vaccination plans, particularly in developing countries. METHODS: A descriptive-analytical cross-sectional study was conducted. Self-completed electronic surveys directed to PLWHA were performed via Twitter in February 2021, using accounts of HIV activists. RESULTS: 460 (87.1%) participants were willing to be vaccinated with any COVID-19 vaccine. The reasons for that were listed as 1) the belief that vaccination prevents both the COVID-19 infection (81.3%) as well as being a spreader (52.2%); 2) having a high occupational risk of becoming infected with COVID-19 (22%); and 3) the belief that they would be at high risk of death because of COVID-19 (21.3%). Only 56 (10.6%) participants expressed hesitancy toward vaccination, and 12 (2.2%) stated they did not want to get vaccinated. CONCLUSIONS: Our results may support the prioritization of people living with HIV during the implementation of vaccination plans in developing countries. New strategies should be adopted to overcome the hesitancy and unwillingness toward the COVID-19 vaccination, especially in populations with risk factors for severe disease.
