まとめ
サルコイドーシスリンフォーマ症候群は,腎臓を巻き込むこともあります. 研究者らは,がん細胞が腎臓に直接浸透することなくとも,慢性リンパ球性白血病/小リンパ球性リンパ腫の患者で,粒状間位性腎炎を発見した.
科学分野:
- ネフロロジーはネフロロジーを用います.
- 腫瘍学 腫瘍学
- 病理学 パトロジー
背景:
- サルコイドーシスリンフォーマ症候群は,サルコイドーシスをリンパ性腫瘍と関連付けています.
- 腎臓の粒状間位性腎炎は,慢性リンパ球性白血病/小リンパ球性リンパ腫 (CLL/SLL),通常はがん細胞の近くで知られている.
- 同時期にCLL/SLLの浸透を伴わない腎臓の粒状間接性腎炎の詳細については,これまでの報告はありません.
研究 の 目的:
- CLL/SLL患者の腎臓における粒状間位性腎炎の症例を報告する,しかし,直接的な腫瘍浸透がない.
- サルコイドーシスリンパ腫症候群における腎臓の関与の明確なプレゼンテーションを強調するために.
主な方法:
- 急性腎臓損傷 (AKI) を呈したCLL/SLL患者2人の症例報告.
- AKIの原因を特定するために腎臓生検の分析.
- リンパ腺症を含む放射線学的発見のレビュー.
主要な成果:
- 両方の患者は,AKIと広範なリンパ腺症を患っていました.
- 腎臓バイオプシでは,CLL/SLLの証拠のない分散型粒状間位性腎炎が予期せぬ形で明らかになった.
- 患者は免疫抑制薬および/またはクローン指向療法を受けた.
結論:
- 同時期にCLL/SLLの浸透がない場合,腎臓における粒状間位性腎炎の最初の組織学的に確認された症例を提示します.
- 腎臓の粒状間位性腎炎は,直接の腫瘍浸透とは無関係に,CLL/SLL患者で発生することが示されている.
- 免疫抑制薬/クローン指向療法による治療は,これらの患者で腎臓の機能を改善した.

Kidney Structure
75.5K
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.

Data Reporting and Recording
5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Antigens Involved in Adaptive Immunity
1.6K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Nephrotic Syndrome I : Introduction
697
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...
