猪链球菌致脑膜炎并发双耳全聋1例报告

A Case Report of Meningitis Caused by Streptococcus suis Complicated with Total Deafness in Both Ears

摘要: 目的：本研究报道一例猪链球菌感染导致的化脓性脑膜炎合并双侧极重度混合性聋的临床病例，旨在为该疾病的诊断和治疗提供临床参考依据。方法：通过对该病例的系统分析，并结合文献复习，探讨其临床特征及干预治疗策略。结果：病例分析显示，该患者为中年男性，急性起病，主要表现为发热、头痛、头晕及快速进展的双侧听力下降，经病原学检测确诊为猪链球菌性脑膜炎。经过规范的抗感染治疗(包括敏感抗生素和糖皮质激素的应用)，患者感染得到有效控制，但双侧仍遗留严重的永久性听力损失。结论：本案例提示，猪链球菌感染起病急骤，病情进展迅速，听力障碍并发症发生率高。对于此类患者，在感染控制后可尽早行听力康复评估，当传统治疗无效时，可考虑早期人工耳蜗植入等干预措施以改善预后。

Abstract: Objective: This study reports a clinical case of purulent meningitis caused by Streptococcus suis infection complicated with bilateral extremely severe mixed deafness, aiming to provide clinical reference for the diagnosis and treatment of this disease. Methods: Through systematic analysis of the case and literature review, the clinical characteristics and intervention treatment strategies were explored. Results: The case analysis showed that the patient was a middle-aged male with acute onset mainly presenting with fever, headache, dizziness and rapidly progressing bilateral hearing loss. The diagnosis of Streptococcus suis meningitis was confirmed by pathogen detection. After standardized anti-infection treatment (including the application of sensitive antibiotics and glucocorticoids), the infection was effectively controlled, but severe permanent bilateral hearing loss remained. Conclusion: This case suggests that Streptococcus suis infection has an acute onset, rapid disease progression, and a high incidence of hearing impairment complications. For such patients, hearing rehabilitation assessment should be conducted as early as possible after infection control. When traditional treatment is ineffective, early cochlear implantation and other intervention measures can be considered to improve prognosis.
