まとめ
常染色体優性多発性嚢胞腎疾患(ADPKD)患者における肝嚢胞感染症は、再発することが多い。抗生物質治療期間の延長(28日以上)により、これらの重篤な感染症に対する治療失敗、再発、再燃のリスクが低減する。
科学分野:
- 腎臓病学、感染症学、肝臓病学
背景:
- 肝嚢胞感染症は、常染色体優性多発性嚢胞腎疾患(ADPKD)において稀ではあるが重篤な合併症である。ADPKD関連肝嚢胞感染症の最適な管理戦略は確立されていない。本研究では、ADPKD患者における肝嚢胞感染症の治療成績を調査する。
主な方法:
- 62人の患者と112件の肝嚢胞感染症エピソードを含む多施設共同後ろ向き研究。感染症は、臨床的、検査室的(CRP 50 mg/l以上)、および画像診断(CT、18FDG-PET/CT、MRI)基準、または嚢胞穿刺により確認された。治療失敗、再発(2ヶ月未満)、再燃(2ヶ月以上)の決定要因を分析した。
結論:
- 肝嚢胞感染症の管理には、抗生物質治療期間の慎重な検討が必要である。28日以上の抗生物質治療は、治療失敗、再発、再燃の減少と関連している。腎嚢胞感染症の既往は再発リスクを高めるため、注意深い経過観察が必要である。

Acute Kidney Injury III: Clinical Manifestations
827
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
