まとめ
本研究は、死亡率が高い疾患である小児敗血症性ショックにおけるコルチコステロイドの使用を調査する。結果は、この重症小児疾患の治療ガイドラインを明確にするだろう。
科学分野:
- 小児集中治療医学
- 小児重症疾患
- 小児集中治療室(PICU)研究
背景:
- 敗血症性ショックは、小児集中治療室への入院の重大な原因であり、罹患率と死亡率が高い。
- 小児敗血症性ショックにおけるコルチコステロイド使用に関する現在のエビデンスは決定的ではなく、臨床管理における不確実性につながっている。
- 既存のガイドラインでは、この患者集団におけるコルチコステロイド投与に関する決定的な推奨が欠如している。
主な方法:
- 約50のPICUが参加する、実用的、多施設共同、国際共同、ランダム化、二重盲検、プラセボ対照試験。
- 敗血症性ショックと診断された最大500人の小児患者(生後1ヶ月から17歳8ヶ月)の登録。
- 経静脈ヒドロコルチゾン(2 mg/kgボーラス、その後1 mg/kgを6時間ごと)またはプラセボを、血管作動性/強心薬注入の中止後12時間、または最大7日間投与する。
結論:
- 本試験は、敗血症性ショックにおけるコルチコステロイドの利点とリスクを評価する、初めて十分に検出力のある小児試験である。
- 本試験の結果は、小児敗血症性ショックの管理における将来の臨床診療ガイドラインに情報を提供する。
- 決定的なデータは、敗血症性ショックを呈する重症児におけるコルチコステロイド投与の決定を導くだろう。

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

COPD: Management Using Bronchodilators and Corticosteroids
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...
Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...
Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
Pharmacokinetics in Pediatric Patients: Drug Distribution
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
Pharmacokinetics in Pediatric Patients: Drug Excretion
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
