摘要:
目的 探究不同浓度碳酸氢钠漱口液联合制霉菌素对系统性红斑狼疮(SLE)患者口腔及肺部感染的预防效果,为临床防治提供科学参考。 方法 选取2023年4月—2024年5月中国人民解放军空军军医大学第一附属医院收治的97例SLE患者为研究对象,采用随机数字表法分为A组32例、B组32例、C组33例。A组使用制霉菌素漱口液,B组在A组的基础上加用2%碳酸氢钠漱口液,C组在A组的基础上加用4%碳酸氢钠漱口液。比较3组患者口腔及肺部感染率、感染发生和治愈时间、口腔pH值和疼痛程度。 结果 C组口腔真菌感染率[9.09%(3/33) vs. 37.50%(12/32) vs. 31.25%(10/32)]和肺部真菌感染率[6.06%(2/33) vs. 31.25%(10/32) vs. 25.00%(8/32)]低于A组和B组(P<0.05)。口腔真菌感染、肺部真菌感染发生时间A组<B组<C组,治愈时间A组>B组>C组(P<0.05)。A组和B组口腔感染程度较C组严重(P<0.05)。患者第1天、第5天及第10天含漱后的口腔pH值与VAS评分A组<B组<C组(P组间<0.05),且随着时间延长,VAS评分差异逐渐减小(P交互<0.05)。 结论 4%的碳酸氢钠漱口液联合制霉菌素漱口液可提高SLE患者口腔pH值,降低口腔及肺部真菌感染率,缩短治疗时间,预防效果显著。 Abstract:Objective To investigate the preventive efficacy of sodium bicarbonate mouthwash at various concentrations combined with nystatin against oral and pulmonary infections in patients with systemic lupus erythematosus(SLE), and to provide evidence for clinical prevention and treatment. Methods A total of 97 SLE patients admitted to the First Affiliated Hospital of the Military Medical University of the Chinese People's Liberation Army Air Force from April 2023 to May 2024 were randomly assigned to three groups: Group A (n=32), Group B (n=32) and Group C (n=33). Group A received nystatin mouthwash alone. Group B received nystatin plus 2% sodium bicarbonate mouthwash. Group C received nystatin plus 4% sodium bicarbonate mouthwash. We compared oral and pulmonary fungal infection rates, time to infection onset and resolution, oral pH levels and pain intensity among the groups. Results Group C had lower rates of oral fungal infection[9.09% (3/33) vs.37.50% (12/32) vs.31.25% (10/32)] and pulmonary fungal infection [6.06% (2/33) vs.31.25% (10/32) vs.25.00% (8/32)] compared to Groups A and B(P < 0.05). The onset of both oral and pulmonary fungal infections occurred earliest in Group A and latest in Group C, while cure times were longest in Group A and shortest in Group C (P < 0.05). Oral infection severity was higher in Groups A and B than in Group C(P < 0.05). After mouth rinsing on days 1, 5, and 10, oral pH and VAS scores were lowest in Group A and highest in Group C (Pintergroup < 0.05). These differences decreased over time(Pinteraction < 0.05). Conclusion Combining 4% sodium bicarbonate mouthwash with nystatin increases oral pH in SLE patients, reduces the risk of oral and pulmonary fungal infections, shortens treatment time and provides effective prophylaxis. -
