Insights

Statins did not prevent chronic kidney disease (CKD) in HIV-infected men, though they were linked to higher albumin-to-creatinine ratio (ACR) and a modest slowing of kidney function decline in those with proteinuria.

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Pharmacology

Background:

  • Chronic kidney disease (CKD) is prevalent in HIV-infected individuals.
  • Statins possess cholesterol-lowering and pleiotropic properties that may mitigate CKD development and progression.

Purpose of the Study:

  • To investigate the association between statin use and kidney damage biomarkers in HIV-infected men.
  • To evaluate the impact of statins on the progression of kidney function and the incidence of CKD in this population.

Main Methods:

  • Cross-sectional and longitudinal analyses were performed on 850 HIV-infected men from the Multicenter AIDS Cohort Study.
  • Urine biomarkers of kidney damage and estimated glomerular filtration rate (eGFR) were assessed.
  • Inverse probability weighting was used to control for confounding factors related to statin use.

Main Results:

  • Statin use was associated with a 4.0% increase in baseline albumin-to-creatinine ratio (ACR) but not other urine biomarkers.
  • No overall association was found between statin use and annual eGFR decline.
  • Among participants with proteinuria, statin use showed a modest association with slower eGFR decline.

Conclusions:

  • Statin use was linked to elevated baseline ACR but not tubulointerstitial injury biomarkers.
  • A modest benefit on eGFR decline was observed only in HIV-infected men with pre-existing proteinuria.
  • Findings suggest a limited role for statins in reducing CKD risk among HIV-infected men, though confounding by indication is a consideration.

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.

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Association Areas of the Cortex01:21

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Associative Learning01:27

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Somatosensory, Motor, and Association Cortex

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
