Neonatal acute renal failure

Objective: Covid-19 poses a major risk during pregnancy and postpartum, resulting in an increase in maternal mortality worldwide, including in Brazil; however, little research has been conducted into cases of a near miss. This study aimed to describe the frequency of COVID-19-related near miss and deaths during pregnancy or in the postpartum in referral centers in northeastern Brazil, as well as the clinical, epidemiological, and laboratory characteristics of the women who experienced a severe maternal outcome...

The primary objective was to determine the epidemiologic influence of AKI awareness among physicians in a mixt paediatric population, including neonates. This single-centre, multiyear, observational retrospective study included all admitted patients between first of July 2014 and 31 December 2021. AKI was identified in 2194 patients out of the 128,036 hospital admissions with 129,936 serum creatinine measurements. Matching comparisons were used between AKI aware and AKI non-aware patients. The overall incidence of AKI was 1...

OBJECTIVE: To evaluate whether there are individual- and population-level associations between chronic hypertension and pregnancy complications, and to assess differences across seven racial-ethnic groups. METHODS: This population-based study used linked vital statistics and hospitalization discharge data from all live and stillbirths in California (2008-2018), Michigan (2008-2020), Oregon (2008-2020), Pennsylvania (2008-2014), and South Carolina (2008-2020). We used multivariable log-binomial regression models to estimate risk ratios (RRs) and population attributable risk (PAR) percentages with 95% CIs for associations between chronic hypertension and several obstetric and neonatal outcomes, selected based on prior evidence and pathologic pathways...

INTRODUCTION: Unique aspects of neonatal renal physiology enhance the occurrence of Acute Kidney Injury (AKI) as a complication of neonatal sepsis. The study sought to determine prevalence of AKI and its characteristics in neonates with suspected sepsis. METHODS: A cross-sectional study was conducted at Kenyatta National Hospital among neonates aged 0-28 days. AKI was defined as serum creatinine of more than 100µmmol/l. RESULTS: Among 332 neonates included 120 had AKI giving a prevalence of 36...

Generalized arterial calcification of infancy (GACI) is a rare condition characterized by diffuse arterial calcification within the internal elastic lamina associated with intimal proliferation leading to stenosis of great and medium-sized vessels, which causes end-organ damage and loss of life during infancy. The clinical presentation of acute renal failure with normal cardiac function is rare. A 7-day-old female neonate was admitted with a clinical impression of late-onset neonatal sepsis, meningitis, and acute kidney injury after developing a high-grade fever, abnormal body movements, and vomiting of the ingested matter associated with decreased urinary output...

Acute kidney injury is a frequent complication for critical newborns. Its management is a significant challenge, especially in extremely low-birth-weight (ELBW) infants. Currently, peritoneal dialysis (PD) is the most manageable treatment. However, data are lacking regarding when diuresis can be declared irreversible relative to the start of PD. A female infant born at 28 + 0 weeks with a birth weight of 800 g by monochorionic diamniotic pregnancy, complicated by twin-to-twin transfusion syndrome, developed acute renal failure on the second day of life because of long-term intrauterine hypoperfusion...

INTRODUCTION: Nephrotoxic medication (NTM) is one of the common causes of acute kidney injury (AKI) in critically ill infants. Current knowledge about the long-term effects of NTM exposure and associated AKI during the neonatal period and early infancy is limited. Hence, we aimed to explore the risk of chronic kidney disease (CKD) after NTM-AKI in this age group. METHODS: We performed a cross-sectional study including children 2-7 years of age, who had a history of high NTM exposure during NICU hospitalization...

UNLABELLED: Continuous Renal Replacement Therapy (CRRT) machines are used off-label in patients less than 20 kg. Infant and neonates-dedicated CRRT machines are making their way into current practice, but these machines are available only in select centres. This study assesses the safety and efficacy of CRRT using adult CRRT machines in children ≤ 10 kg and to determines the factors affecting the circuit life in these children. DESIGN: Retrospective cohort study of children ≤ 10 kg who received CRRT (January 2010-January 2018) at a PICU in a tertiary care centre in London, UK...

BACKGROUND: Acute kidney injury occurs commonly in the Neonatal Intensive Care Unit and is associated with increased mortality and morbidity. We report a case of a neonate with congenital heart disease who developed acute kidney injury after cardiac surgery, administration of iodinated contrast media for cardiac catheterization, and a combination of nephrotoxic drugs. CASE REPORT: A term neonate without a prenatal diagnosis of congenital heart disease and with a good postnatal transition was transferred at 13 days of life to the MS Curie Emergency Hospital for Children, Newborn Intensive Care Unit, from a regional hospital where he was admitted at 10 days of life with severe general status, respiratory distress, cyanosis, and arterial hypotension...

Background One of the most prevalent medical issues observed during pregnancy is hypertension. Hypertensive disorders of pregnancy (HDP) and their consequences affect around 5-10% of all pregnancies globally. Preeclampsia is caused by endothelial dysfunction, which causes widespread endothelial leakage and contributes to potentially fatal consequences, such as eclampsia, placental abruption, disseminated intravascular coagulation (DIC), severe renal failure, pulmonary edema, and hepatocellular necrosis. As a result, looking for predictive markers for at-risk pregnancies that can suggest poor maternal or fetal outcomes is critical...

UNLABELLED: Abdominal wall defects are serious birth defects, with long periods of hospitalization and significant costs to the medical system. Nosocomial infection (NI) may be an additional risk factor that aggravates the evolution of newborns with such malformations. METHODS: in order to analyze the factors that may lead to the occurrence of NI, we performed a retrospective study over a period of thirty-two years (1990-2021), in a tertiary children's hospital; 302 neonates with omphalocele and gastroschisis were eligible for the study...

The rate of solid organ transplant in reproductive-aged patients has increased in the past 3 decades. Concurrently, the range of medical immunosuppressive agents has increased, making it safer for reproductive-aged individuals who have received transplants to attempt and continue a pregnancy. In this Consult, we review the general considerations and contemporary approach to medical and obstetrical management of pregnant solid organ transplant recipients, discuss the perinatal outcomes and incidence of graft rejection specific to the most common types of organ transplants, and provide management recommendations based on the available evidence...

INTRODUCTION: Patent ductus arteriosus (PDA) causes severe morbidity in premature infants. Although the use of indomethacin is the standard therapy for PDA, it is sometimes not applicable because of its adverse effects, such as renal and platelet dysfunctions. Paracetamol has emerged as an alternative to indomethacin owing to its excellent safety profile in infants. Of the recently reported case series and clinical trials on the use of paracetamol for PDA, there are few reports in Japan on paracetamol use in preterm infants...

BACKGROUND: The mortality rate of acute kidney injury (AKI) in low-birth-weight premature infants with acute renal failure is extremely high. Since small hemodialysis catheters do not exist, peritoneal dialysis (PD) is the most suitable dialysis method. At present, only a few studies have reported cases of PD in low-birth-weight newborns. CASE DESCRIPTION: On September 8, 2021, a 10-day-old, low-birth-weight preterm infant, who presented with neonatal respiratory distress syndrome and acute renal failure, was admitted to the Second Affiliated Hospital of Kunming Medical University, China...

Fetal urinomas are often diagnosed in prenatal ultrasonography. The etiology is usually an obstructive uropathy leading to hydronephrosis and increased intrarenal pressure putting future kidney function at risk. Rupture of pyelocaliceal system in such cases may lead to retroperitoneal urinoma or urinary ascites, sepsis, uraemia, and acute renal failure. On the other hand, this may serve as "pop-off valve" mechanism decreasing intrarenal pressure and protecting from definitive kidney function loss. We present a case of a newborn girl with a retroperitoneal urinoma, ascites, uraemia, and obstruction of a solitary right kidney, which was successfully treated minimally invasively through peritoneal and retroperitoneal drainage and intubation of the right ureter with a DJ stent shortly after birth...

The work describes a case of rare neonatal systemic juvenile xanthogranuloma with an initial damage of the scalp, limbs, back and abdomen, multiple damages of the parenchyma of both lungs, spleen and liver with the development of a severe form of congenital cholestatic hepatitis. The diagnosis was established on the basis of histopathological and immunohistochemical examination of the skin nodules. The child on the background of therapy under the Langerhans cell histiocytosis III program achieved a partial response, which was manifested by a reduction of granulomatous formations on the skin, elimination of liver failure, but retained hepatosplenomegaly, specific lesions of the lung parenchyma, liver, and left kidney...

BACKGROUND: Kidney function impairment in pregnancy is challenging, with incidence and prognosis only partially known. Studies concerning maternal and fetal outcomes in pregnancies occurring in patients with renal injury and the therapeutic strategies for improving the prognosis of these patients are scarce due to the limited number of cases reported. OBJECTIVES: We aimed to establish correlations between the main maternal and fetal outcomes in patients with severe CKD or AKI in pregnancy to improve the prognosis, referring to a control group of patients with mild kidney impairment...

BACKGROUND: The incidence of pregnancy-associated cancer (PAC), comprising cancer diagnosed during pregnancy or within one year postpartum, is increasing. We investigated the obstetric management and outcomes of women with PAC and their babies. METHODS: A population-based observational study of all women who gave birth between 1994 and 2013 in New South Wales, Australia. Women were stratified into three groups: those diagnosed during pregnancy (gestational cancer group), those diagnosed within one year of giving birth (postpartum cancer group), and a no-PAC group...

OBJECTIVE: To evaluate whether urine output (UO), rarely assessed in the literature, is associated with relevant neonatal outcomes in very preterm infants, and which UO threshold may be the most clinically relevant. DESIGN: Retrospective cohort study. SETTING: Two Level IV neonatal intensive care units. PATIENTS: Very preterm infants born between 240/7 and 296/7 weeks of gestation documented with eight UO measurements per day between postnatal day 1 and day 7...

Aim To determine an outcome of acute kidney injury (AKI) in critically ill children (CIC) who needed renal replacement therapy (RRT) and were admitted to the Paediatric and Neonatal Intensive Care Unit (PICU and NICU) at the Paediatric Clinic, University Clinical Centre Sarajevo (UCCS). Methods The research included 81 children with AKI. The Kidney Disease: Improving Global Outcomes (KDIGO) criteria to define AKI was used. Other laboratory findings and imaging tests were made depending on children's primary disease that led to the AKI...
