Insights

Stiffness of the liver, spleen, and kidneys is increased in children with HIV. Shear wave elastography (SWE) can detect early organ changes in these patients, even with normal lab tests and ultrasounds.

Area of Science:

  • Pediatric Medicine
  • Hepatology
  • Nephrology

Background:

  • Human Immunodeficiency Virus (HIV) infection can affect multiple organs.
  • Assessing organ stiffness may reveal subclinical changes in pediatric HIV.
  • Shear wave elastography (SWE) is a non-invasive imaging technique.

Purpose of the Study:

  • To evaluate liver, spleen, and kidney stiffness in HIV-monoinfected children using SWE.
  • To compare organ stiffness between HIV-infected children and healthy controls.
  • To determine if SWE can detect early parenchymal changes.

Main Methods:

  • Ultrasound and SWE examinations of the liver, spleen, and kidneys.
  • Inclusion of 21 HIV-monoinfected children and 37 healthy controls.
  • Comparison of stiffness values between groups and correlation with laboratory and ultrasonographic findings.

Main Results:

  • HIV-monoinfected children showed significantly higher liver, spleen, and kidney stiffness compared to controls.
  • Increased stiffness was observed even in children with normal laboratory parameters and ultrasonographic findings.
  • Minor ultrasonographic abnormalities like hepatosplenomegaly and hepatosteatosis were noted in a small subset of patients.

Conclusions:

  • Organ stiffness is elevated in HIV-monoinfected children.
  • SWE is a valuable tool for detecting early parenchymal changes in pediatric HIV.
  • SWE can identify subclinical organ alterations undetectable by standard lab tests and ultrasound.

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

The Wave Nature of Light02:12

The Wave Nature of Light

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Kidney Structure01:45

Kidney Structure

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.
