概括
维生素D缺乏 (25(OH) D) 与犬类肠道病有关,与其他形式相比,蛋白质丧失肠道病 (PLE) 和免疫抑制剂反应性肠道病 (IRE) 的水平较低. 在这些狗中,炎症对25(OH) D有负面影响.
科学领域:
- 兽医医学 兽医医学 兽医医学
- 狗胃肠病学 狗胃肠病学
- 营养生物化学 营养生物化学
背景情况:
- 维生素D缺乏是已知的慢性肠道病变 (CE) 和失去蛋白质的肠道病变 (PLE) 的负面预后因素.
- 在CE中,25-基维生素D (25(OH) D) 状态和特定的临床表型之间的关系尚未得到充分研究.
研究的目的:
- 为了研究不同犬类肠病治疗反应组之间的25...OH) D水平的差异.
- 为了确定25...OH) D状态和CE.狗的临床/诊断数据之间的关联.
主要方法:
- 追溯分析91个狗肠道病变病例.
- 分类为食物反应性肠病 (FRE),微生物群相关调制反应性肠病 (MrMRE),免疫抑制剂反应性肠病 (IRE) 和PLE组.
- 使用UHPLC-MS/MS和多变量线性回归分析量化血清25(OH) D.
主要成果:
- 在肠道病变组之间观察到25...OH) D水平的显著差异 (p < 0.001).
- 与FRE (33 ng/mL) 和MrMRE (37 ng/mL) 组相比,PLE组表现出明显较低的中位数25(OH) D (10.3 ng/mL).
- 与FRE和MrMRE组相比,IRE组也显示了25(OH) D (20 ng/mL) 的降低 (p = 0.006).
- 果糖胺和与25OH) D正相关,而C反应蛋白与25OH) D负相关.
结论:
- 血清25(OH) D水平在不同的犬肠病治疗反应组之间有显著差异.
- 在CE中,炎症会对25(OH) D状态产生负面影响,这与临床严重程度和血清蛋白生物标志物有关.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
