まとめ
高齢および腎機能低下は、カペシタビンとオキサリプラチンの併用(CAPOX)化学療法を受けている患者における重度下痢の主なリスク因子である。アンジオテンシン受容体拮抗薬(ARB)またはACE阻害薬の使用は、このリスクを増加させなかった。
科学分野:
- 腫瘍学
- 消化器病学
- 薬理学
背景:
- 以前の研究では、カペシタビンとオキサリプラチンの併用(CAPOX)とアンジオテンシン受容体拮抗薬(ARB)の関連が、重度の下痢リスクを増加させることが示唆されていた。
- 他の潜在的なリスク因子を考慮して、これらの所見を検証するために、より大規模な多施設共同研究が実施された。
研究 の 目的:
- CAPOXとARB/ACE阻害薬の併用および重度の下痢/腸炎との関連を検証すること。
- CAPOXで治療された患者における重度の胃腸毒性の独立したリスク因子を特定すること。
主な方法:
- CAPOXで治療された362人の大腸がん患者の後ろ向き多施設共同研究。
- 主要評価項目:グレード3以上下痢および/または腸炎。
- リスク因子を評価するためにロジスティック回帰モデル(未調整および調整済み)を使用した。
主要な成果:
- 多変量解析において、65歳以上(OR 2.71)および推定糸球体濾過量(eGFR)60 ml/分未満(OR 5.4)が、重度の下痢/腸炎の有意な独立したリスク因子であった。ARBまたはACE阻害薬の併用は、リスク増加と有意な関連は見られなかった。
結論:
- 年齢および腎機能障害は、重度のCAPOX誘発性下痢/腸炎の重要な独立したリスク因子である。
- ARB/ACE阻害薬とCAPOXによる重度の胃腸毒性との間に以前示唆されていた関連は、この大規模な研究では確認されなかった。

Factors Affecting the Risk of Infection
13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Drugs for Treatment of Diarrhea-Predominant IBS
722
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Relative Risk
2.2K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Transcription Factors
82.8K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Induced Pluripotent Stem Cells
28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Factors Affecting Solubility
37.2K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:
