Cryptococcal meningitis (CM) caused by encapsulated opportunistic yeast Cryptococcus neoformans is an important contributor to morbidity and mortality in people living with human immunodeficiency virus/acquired immunodeficiency syndrome (PLHAs). Early diagnosis of such patients is the key to their therapeutic success. A retrospective study was conducted to evaluate the clinical features, laboratory findings, and prevalence of CM among hospitalized PLHAs in a tertiary care setting.
A total of 112 clinically diagnosed CM patients were subjected to cerebrospinal fluid analysis and tests for human immunodeficiency virus antibodies by the standard laboratory operating procedures.
Out of 112, 16 showed a definite diagnosis of C. neoformans with the prevalence of 14.3%. Males in the age group of 21-40 years were most commonly affected than females. The clinical manifestations observed were fever and headache (100%), followed by altered sensorium (93.7%), neck stiffness (75%), and vomiting (62.5%). Overall, Cluster of differentiation 4 (CD4) T-lymphocytes count was <100 cells/μl except 1 case in which the CD4 T-lymphocytes count was 137 cells/μl. No concomitant cryptococcal and tubercular meningitis case was detected. All 16 patients responded initially to induction therapy of IV amphotericin B 1 mg/kg and fluconazole 800 mg daily for 2 weeks. Subsequently, 4 (25%) patients were lost for follow-up and 2 (12.5%) patients expired during their hospital stay.
As the clinical and radiological pictures of CM are often non-pointing, routine mycological evaluation is necessary for early definite diagnosis and subsequent initiation of appropriate therapy as the majority of patients respond well to treatment if started early.
由包膜机会性酵母新型隐球菌引起的隐球菌性脑膜炎(CM)是导致人类免疫缺陷病毒/获得性免疫缺陷综合征(PLHAs)患者发病和死亡的重要因素。对此类患者进行早期诊断是治疗成功的关键。本研究进行了一项回顾性研究,以评估三级医疗机构中住院PLHAs患者的CM临床特征、实验室检查结果及患病率。
共112例临床诊断为CM的患者按照标准实验室操作程序接受了脑脊液分析及人类免疫缺陷病毒抗体检测。
112例患者中,16例确诊为新型隐球菌感染,患病率为14.3%。21至40岁年龄组的男性比女性更易受影响。观察到的临床表现为发热和头痛(100%),其次是意识改变(93.7%)、颈部僵硬(75%)和呕吐(62.5%)。总体而言,除1例CD4 T淋巴细胞计数为137个/μl外,分化簇4(CD4)T淋巴细胞计数均<100个/μl。未检测到合并隐球菌性和结核性脑膜炎病例。所有16例患者最初对静脉注射两性霉素B 1mg/kg和氟康唑每日800mg的诱导治疗反应良好,持续2周。随后,4例(25%)患者失访,2例(12.5%)患者在住院期间死亡。
由于CM的临床和影像学表现往往不具有指向性,因此进行常规真菌学评估对于早期明确诊断及随后开始适当治疗是必要的,因为大多数患者如果早期开始治疗,对治疗反应良好。
