Abstract:
Objective:To investigate the clinical efficacy of ventriculo-peritoneal shunt (VPS) in acquired immunodeficiency syndrome (AIDS) patients with cryptococcal neoformans meningitis (CNM).Methods:Patients with AIDS and CNM who were hospitalized in Guangzhou Eighth People′s Hospital, Guangzhou Medical University from January 2015 to June 2020 were included and divided into VPS group and conventional treatment group.The data including symptoms and signs of meningitis, cerebrospinal fluid (CSF) pressure, CSF routine examination, ink staining, Cryptococcus culture and Cryptococcus culture negative time were obtained, and the clinical efficacy compared between the two groups after six and 48 weeks of treatment.Two independent samples t test or chi-square test was used for statistical analysis. Results:Among 66 AIDS patients with CNM, 26 cases in VPS group were (35.7±11.9) years, and 11 cases (42.3%) had CSF pressure> 330 mmH 2O (1 mmH 2O=0.009 8 kPa) at admission, 25 cases (96.2%) were positive for ink staining, and 20 cases (76.9%) had positive culture of Cryptococcus neoformans in CSF. There were 40 cases in the conventional treatment group with age of (38.9±12.9) years, 15 cases (37.5%) had CSF pressure>330 mmH 2O, 32 cases (80.0%) were positive for ink staining, and 31 cases (77.5%) were positive for culture of Cryptococcus neoformans in CSF. There were no significant differences of age, the proportion of patients with CSF pressure>330 mmH 2O, positive rate of ink staining, positive rate of Cryptococcus culture between the two groups ( t=-1.02, χ2=0.15, 3.49 and 0.00, respectively; all P>0.050). All patients were administrated with antifungal treatment, decreasing CSF pressure treatment, nutritional support and symptomatic treatment after admission. VPS was performed in patients with poor responses after medical conservative treatment in VPS group. At week six of treatment, the recovery rate of CSF pressure in VPS group was 57.7%(15/26), and the partial remission rate was 73.1%(19/26), which were both higher than those in conventional treatment group (31.0%(9/29) and 47.5%(19/40), respectively). The differences were both statistically significant ( χ2=3.96 and 4.22, respectively, both P<0.050). At week 48 of treatment, the recovery rate of CSF pressure in VPS group was 92.3%(24/26), the negative rate of Cryptococcus culture in CSF was 100.0%(20/20), and the complete remission rate was 46.2%(12/26), which were all higher than those in conventional treatment group (37.9%(11/29), 67.7%(21/31) and 20.0%(8/40), respectively). The differences were all statistically significant ( χ2=17.52, 8.03 and 5.10, respectively, all P<0.050). In VPS group, 22 cases were complete or partial remission, four cases were ineffective, and no death occurred, while there were 23 cases of complete or partial remission, 12 cases of ineffective and five cases of death in the conventional treatment group. The proportion of ineffective or death in the VPS group was 15.4%(4/26), which was lower than 42.5%(17/40) in the conventional treatment group. The difference was statistically significant ( χ2=5.34, P=0.021). Conclusions:VPS in AIDS patients with CNM could significantly improve the treatment outcomes, and reduce the rates of treatment failure and mortality.
