While there are increasing reports of acute kidney injury among hospitalized adults with COVID-19, there is still limited information on renal complications associated with COVID-19 in children. The ...cause of kidney involvement in COVID-19 is likely multifactorial, and appears to involve a complex process, including complement dysregulation and thrombotic microangiopathy. We present a pediatric case of COVID-19 and renal failure due to thombotic microangiopathy, successfully treated with eculizumab.
The success of genomic medicine hinges on the implementation of genetic knowledge in clinical settings. In novel subspecialties, it requires that clinicians refer patients to genetic evaluation or ...testing, however referral is likely to be affected by genetic knowledge.
An online survey was administered to self-identified nephrologists working in the United States. Nephrologists’ demographic characteristics, genetic education, confidence in clinical genetics, genetic knowledge, and referral rates of patients to genetic evaluation were collected.
In total, 201 nephrologists completed the survey. All reported treating patients with genetic forms of kidney disease, and 37% had referred <5 patients to genetic evaluation. A third had limited basic genetic knowledge. Most nephrologists (85%) reported concerns regarding future health insurance eligibility as a barrier to referral to genetic testing. Most adult nephrologists reported insufficient genetic education during residency (65%) and fellowship training (52%). Lower rating of genetic education and lower knowledge in recognizing signs of genetic kidney diseases were significantly associated with lower number of patients referred to the genetic evaluation (P < .001). Most nephrologists reported that improving their genetic knowledge is important for them (>55%).
There is a need to enhance nephrologists’ genetic education to increase genetic testing use in nephrology.
Multisystem inflammatory syndrome in children (MIS-C) is a recently identified entity in association with COVID-19. AKI has been widely reported in patients with primary COVID-19 infection. However, ...there is a paucity of literature regarding renal injury in MIS-C. We aim to characterize AKI in MIS-C in this cohort identified at a major children's hospital in New York City during the COVID-19 pandemic.
We conducted a retrospective cohort study of children 0-20 years old admitted to Morgan Stanley Children's Hospital (MSCH) between April 18th and September 23rd, 2020. Patients were included if they met criteria for MIS-C on the basis of CDC guidelines. All patients were evaluated for the presence of AKI, and AKI was staged according to KDIGO criteria.
Of the 57 children who met inclusion criteria, 46% (26 of 57) were found to have AKI. The majority of patients (58%; 15 of 26) were classified as KDIGO stage 1. AKI was present upon admission in 70% of those identified. All patients had resolution of AKI at discharge, with 61% achieving recovery by day 2. One patient required dialysis. When compared with those without renal injury, the AKI cohort was older (
<0.001) and had higher median peak values of CRP (
<0.001), IL-6 (
=0.02), ferritin (
<0.001), and procalcitonin (
=0.02). More patients with AKI had left ventricular systolic dysfunction (
<0.001) and lymphopenia (
=0.01) when compared with those without AKI. No differences in body mass index or sex were found.
Although children with MIS-C may develop AKI, our study suggests that most experience mild disease, swift resolution, and promising outcome. Older age, increased inflammation, and left ventricular systolic dysfunction may be risk factors. Our study highlights the substantial differences in epidemiology and outcomes between AKI associated with pediatric MIS-C versus primary COVID-19 infection.
To evaluate whether hypertensive disorders of pregnancy, including gestational hypertension, preeclampsia, and eclampsia, are associated with cognitive decline later in life among U.S. ...Hispanic/Latina individuals.
The HCHS/SOL (Hispanic Community Health Study/Study of Latinos) is a prospective population-based study of Hispanic/Latino individuals aged 18-74 years from four U.S. communities. This analysis included parous individuals aged 45 years or older who participated in the HCHS/SOL clinic study visit 1 (2008-2011) neurocognitive assessment and subsequently completed a repeat neurocognitive assessment as part of the Study of Latinos-Investigation of Neurocognitive Aging ancillary study visit 2 (2015-2018). Hypertensive disorders of pregnancy were assessed retrospectively by self-report of any gestational hypertension, preeclampsia, or eclampsia. Cognitive functioning was measured at both study visits with the Brief Spanish-English Verbal Learning Test, Digit Symbol Substitution, and Word Fluency. A regression-based approach was used to define cognitive decline at visit 2 as a function of cognition at visit 1 after adjustment for age, education, and follow-up time. Linear regression models were used to determine whether hypertensive disorders of pregnancy or their component diagnoses were associated with standardized cognitive decline after adjustment for sociodemographic characteristics, clinical and behavioral risk factors, and follow-up time.
Among 3,554 individuals included in analysis, the mean age was 56.2 years, and 467 of individuals (13.4%) reported at least one hypertensive disorder of pregnancy. Individuals with hypertensive disorders of pregnancy compared with those without were more likely to have higher mean systolic blood pressure, fasting glucose, and body mass index. After an average of 7 years of follow-up, in fully adjusted models, gestational hypertension was associated with a 0.17-SD relative decline in Digit Symbol Substitution scores (95% CI, -0.31 to -0.04) but not other cognitive domains (Brief Spanish-English Verbal Learning Test or Word Fluency). Neither preeclampsia nor eclampsia was associated with neurocognitive differences.
The presence of preeclampsia or eclampsia was not associated with interval neurocognitive decline. In this cohort of U.S. Hispanic/Latina individuals, gestational hypertension alone was associated with decreased processing speed and executive functioning later in life.
