Abstract

Objective To investigate the diagnostic value of cerebrospinal fluid GeneXpert MTB/RIF and cerebrospinal fluid LAMP for tuberculous meningitis. Methods Selected 110 cases of tuberculous meningitis in patients who were diagnosed and treated,60 patients were treated as tuberculous meningitis group A randomly,50 patients were used as tuberculous meningitis group B,in addition,20 patients with another central nervous system infection were collected as control group,Group A were extracted cerebrospinal fluid in order to send cerebrospinal fluid routine,biochemical,tuberculous smear,GeneXpert MTB/RIF,Group B take cerebrospinal fluid routine biochemical,tuberculous smear,tuberculous culture and LAMP,and cerebrospinal fluid routine,biochemical tuberculous smear,tuberculous culture,GeneXpert MTB/RIF and LAMP were taken from control group. Results In the group A,32 patients were positive in cerebrospinal GeneXpert MTB/RIF,the cerebrospinal fluid GeneXpert MTB/RIF lifampin resistance gene was positive in 3 patients,5 patients were positive in cerebrospinal tuberculous smear with positive rate was 8.3%,10 patients were positive in cerebrospinal fluid tuberculous culture,and the posi⁃ tive rate was 16.7%,32 patients were diagnosed with cerebrospinal fluid GeneXpert MTB/RIF lead to 53.0% posi⁃ tive rate,In the group B,the positive rates of cerebrospinal fluid tuberculous smear,tuberculous culture and LAMP were 8.0%,18.0% and 58.0%,respectively. In the control group,patients had negative result in cerebrospi⁃ nal fluid tuberculous smear,tuberculous culture,GeneXpert MTB/RIF and LAMP. Conclusions Cerebrospinal fluid GeneXpert MTB/RIF and LAMP are good methods for early diagnosis of tuberculous meningitis.
