まとめ

腎臓の脂肪濃度 (PFT) はBMIよりも腎臓の結石の予測に優れている. 肥満に関連したこのマーカーは特定の遺伝子と炎症経路に関わっている可能性があります

科学分野:

腎臓科
放射線科
ゲノミクス
代謝健康

背景:

腎石疾患 (KSD) は,世界的に増加する健康問題です.
肥満 (OB) はKSDの主要なリスク因子であり,代謝機能障害と炎症に関連しています.
体重指数 (BMI) は一般的な肥満の測定値ですが,内臓脂肪については特異性はありません.

研究の目的:

KSDの診断におけるPFTの臨床的有用性を評価する.
OBとKSDを結びつける分子メカニズムを解明する.

主な方法:

413人の患者 (265人のKSD,148人の対照群) の遡及分析.
腹部コンピュータトモグラフィを用いてPFTを測定する.
機械学習 (WGCNA,微分発現分析) を遺伝子発現データに適用する.
内部および外部データセットを使用した診断ノモグラムの開発と検証.
パスウェイの濃縮分析

主要な成果:

KSD患者は対照群と比較してPFTが増加し,BMIよりも診断の精度が高かった.
PFTはKSDの独立した予測因子 (OR=1. 20,P<0. 001) として特定された.
FAM20AとDHRS9が鍵となるハブ遺伝子として,OBに関連する8つの異なる発現遺伝子が発見されました.
診断ノモグラムは高い予測精度を示した.
濃縮分析では,IL-6/JAK/STAT3とTNF-α/NF-κBのシグナル伝達経路が,腎周脂肪とKSDの結合に関与していることが判明した.

結論:

PFTは,KSDリスクの実用的で信頼できるマーカーであり,BMIを上回り,臨床統合に適しています.
FAM20AとDHRS9は,炎症経路経由で腎周脂肪と結石を結びつける可能性があります.
これらの発見は,肥満に関連するKSDの管理のための潜在的な治療目標を提供します.

Urinary Tract Calculi IV: Nutrition Therapy and Prevention

Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

External Anatomy of the Kidney

1.6K

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
