Impact of early-life weight status on urinary tract infections in children: a nationwide population-based study in Korea

Kidney Considerations in Pediatric Obesity

PURPOSE OF REVIEW

Chronic kidney disease (CKD) is a common condition and a major cause of morbidity and mortality in adults, but children and adolescents are also at risk for early kidney injury and development of CKD. Obesity contributes both directly and indirectly to the development of CKD. The purpose of this review is to describe obesity-related kidney disease (ORKD) and diabetic kidney disease (DKD) and their impact in the pediatric population.

RECENT FINDINGS

Although obesity-related CKD in childhood and adolescence is uncommon, nascent kidney damage may magnify the lifetime risk of CKD. Glomerular hyperfiltration is an early phenotype of both ORKD and DKD and typically manifests prior to albuminuria and progressive decline in GFR. Novel treatments for obesity and type 2 diabetes exerting protective effects on the kidneys are being investigated for use in the pediatric population. It is important to understand the impact of obesity on the kidneys more fully in the pediatric population to help detect injury earlier and intervene prior to the onset of irreversible progression of disease and to guide future research in this area.

Childhood Body Mass Index (BMI) and the Risk of Infection: A Narrative Review

Context: Infectious diseases are still one of the main causes of morbidity and mortality in children, especially in developing countries. In various studies, the weight of children has been found to be influential in the risk of occurrence of these diseases or their severity, and sufficient information on this matter can be important in improving the management and prognosis of patients. This study aimed to determine the impact of being underweight or obese on the risk of infection in children Evidence Acquisition: The ISI Web of Sciences, Scopus, PubMed, and Google Scholar databases were reviewed for relevant articles published from 2010 to 2022. The keywords used included: Infections, body mass index, obesity, thinness, underweight, and child. Results: Studies show that underweight children are associated with an increased risk of various parasitic, viral, and bacterial infections or their severity. Being overweight and obese have received less attention, but they have been shown to be effective in some respiratory and urinary infections in children. Conclusions: According to obtained results, being underweight or obese has been linked to an increased risk of various parasitic, viral, and bacterial infections or their severity in children. Therefore, determining the weight of children, even in emergency cases, and considering it, along with other initial evaluations of children with infection, can be effective in improving the management and prognosis of these children.

Obesity and chronic kidney disease: prevalence, mechanism, and management

The prevalence of childhood obesity is increasing worldwide at an alarming rate. While obesity is known to increase a variety of cardiovascular and metabolic diseases, it also acts as a risk factor for the development and progression of chronic kidney disease (CKD). During childhood and adolescence, severe obesity is associated with an increased prevalence and incidence of the early stages of kidney disease. Importantly, children born to obese mothers are also at increased risk of developing obesity and CKD later in life. The potential mechanisms underlying the association between obesity and CKD include hemodynamic factors, metabolic effects, and lipid nephrotoxicity. Weight reduction via increased physical activity, caloric restriction, treatment with angiotensin-converting enzyme inhibitors, and judicious bariatric surgery can be used to control obesity and obesity-related kidney disease. Preventive strategies to halt the obesity epidemic in the healthcare community are needed to reduce the widespread deleterious consequences of obesity including CKD development and progression.
