NEJMがとても役立ちますよ、ということを以前お話ししましたが、
最新号の“Case Records of the MGH”を紹介します。

「Case 28-2019: A 22-Year-Old Woman with Dyspnea and Chest Pain.（NEJM 2019;381:1059-1067.）」

とても深いですね。
鑑別疾患や本病態の解説は学ぶところが多いです。


ついでに、最近のNEJM論文も紹介します。

「CLINICAL PROBLEM-SOLVING: A Terminal Event.（NEJM 2019;381:970-976.）」

画像的にも臨床的にも大変興味深く、勉強になる症例です。
実臨床で、かなり困って二転三転しているのがよくわかります。



「ORIGINAL ARTICLE: Inhaled GM-CSF for Pulmonary Alveolar Proteinosis.（NEJM 2019;381::923-932.）」

日本発の原著論文です。
軽症～中等症の肺胞蛋白症に対するGM-CSF吸入治療に関して検討されています。

Pulmonary alveolar proteinosis is a disease characterized by abnormal accumulation of surfactant in the alveoli. Most cases are autoimmune and are associated with an autoantibody against granulocyte–macrophage colony-stimulating factor (GM-CSF) that prevents clearing of pulmonary surfactant by alveolar macrophages. An open-label, phase 2 study showed some therapeutic efficacy of inhaled recombinant human GM-CSF in patients with severe pulmonary alveolar proteinosis; however, the efficacy in patients with mild-to-moderate disease remains unclear.

In this randomized, controlled trial, inhaled recombinant human GM-CSF was associated with a modest salutary effect on the laboratory outcome of arterial oxygen tension, and no clinical benefits were noted.
