Proton pump inhibitors (PPI) are the most commonly used medication in the world. They are prescribed as an effective treatment choice for gastrointestinal system diseases linked to hyperacidity, especially. Additionally, non-indication and unnecessary use are very common. Many publications in recent times have reported significant side effects. However, there are insufficient studies about the mechanism for these side effects.
Twenty-four Wistar albino rats were used in this study. Rats were divided into 3 groups of control, group-administered H2 receptor blockers and a group-administered PPI. Medications were administered for 30 days intraperitoneal. After 30 days, rats were euthanized and lung tissue was obtained. Lung was stained for immunohistochemical catalase, superoxide dismutase, Glutathione peroxidase, myeloperoxidase, and toluidine blue and investigated with a light microscope. Transmission electron microscopy (TEM) was used to investigate lung tissues and neutrophil leukocytes. Additionally, lung tissue had biochemical hydrogen peroxide (H2O2) levels researched.
H2O2 amounts, produced by lysosomes with important duties for neutrophil functions in lung tissues, were found to be statistically significantly reduced in the group-administered PPI. Results from investigations of specimens obtained with immunohistochemical staining observed increases in antioxidant amounts in the PPI group. Investigation with TEM identified more inflammation findings in the lung tissue from the group-administered PPI compared to the control group and the group-administered H2 receptors.
In conclusion, we identified long-term PPI use disrupts neutrophil leukocyte functions in the lung. All clinicians should be much more careful about PPI use.
质子泵抑制剂(PPI)是世界上最常用的药物。它们被用作治疗胃酸相关胃肠道系统疾病的有效选择,特别是在非适应证和不必要使用的情况下非常常见。最近有许多出版物报道了这些药物的显著副作用。然而,对于这些副作用的机制研究还不够充分。
本研究使用了 24 只 Wistar 白化大鼠。将大鼠分为 3 组:对照组、给予 H2 受体阻滞剂组和给予 PPI 组。药物通过腹腔内注射给药 30 天。30 天后,处死大鼠并获取肺组织。对肺组织进行免疫组织化学染色,检测过氧化氢酶、超氧化物歧化酶、谷胱甘肽过氧化物酶、髓过氧化物酶和甲苯胺蓝,并在光镜下进行观察。使用透射电子显微镜(TEM)观察肺组织和中性粒细胞。此外,还研究了肺组织中的生化过氧化氢(H2O2)水平。
在给予 PPI 的组中,发现肺组织中溶酶体产生的、对中性粒细胞功能至关重要的 H2O2 量显著减少。免疫组织化学染色标本的研究结果表明,PPI 组的抗氧化剂含量增加。TEM 研究发现,与对照组和给予 H2 受体阻滞剂组相比,给予 PPI 的组的肺组织中炎症发现更多。
总之,我们发现长期使用 PPI 会破坏肺内中性粒细胞的功能。所有临床医生在使用 PPI 时都应该更加小心。
