Cerebral toxoplasmosis occurs mainly in immunocompromised hosts as a reactivation of latent infection. In the diagnostic process, magnetic resonance imaging (MRI), serum testing, and biopsy are used. We describe a case of a 43-year-old HIV-positive patient presenting with altered levels of consciousness, aphasia, and hemiparesis. The patient had a history of antiretroviral therapy discontinuation for about 3 years. MRI revealed lesions, suggesting cerebral toxoplasmosis and subacute hemorrhage, serum tests for were positive. Antiparasitics and glycocorticosteroids were administered. A decline in viral load and clinical improvement were observed, however CD4+ T-cell count continued to decrease. The patient's state worsened, he developed CMV and bacterial pneumonia, which led to his death. What is crucial in the management of an HIV-infected patient is effective and continuous antiretroviral therapy. Discontinuation of the treatment may result in AIDS and lead to poor recovery of the CD4+ T-cell population, even after reimplementation of antiretroviral therapy and a decrease in viral load.
脑弓形虫病主要发生在免疫功能低下的宿主中,是潜伏感染的重新激活。在诊断过程中,会使用磁共振成像(MRI)、血清检测和活检。我们描述了一例43岁的HIV阳性患者,该患者出现意识水平改变、失语和偏瘫。该患者有大约3年未进行抗逆转录病毒治疗的病史。MRI显示有病变,提示脑弓形虫病和亚急性出血,血清检测呈阳性。给予了抗寄生虫药物和糖皮质激素。观察到病毒载量下降且临床症状有所改善,然而CD4+T细胞计数持续下降。患者病情恶化,并发了巨细胞病毒和细菌性肺炎,最终导致死亡。对于HIV感染患者的管理,关键在于有效的持续抗逆转录病毒治疗。中断治疗可能导致艾滋病,并导致CD4+T细胞群体恢复不佳,即使在重新实施抗逆转录病毒治疗且病毒载量下降之后也是如此。
