Abstract |
One of the inherent features of clinical microbiology is that substantial time is required for the
culture of infectious organisms. Especially acid fast bacilli require extensive time and labaratory
facilities for reliable recovery. This makes it difficult for clinicians to use the results in early
decisions concerning management of the patient. For these reasons, there has been increasing interest
in developing or refining methods that allow direct detection and identification of microorganisms or
specific immunoglobulins in clinical specimens. The purpose of this article is to define the diagnostic
efficacy of ELISA method in tuberculous meningitis.
PPD-specific Ig G was measured in serum and cerebrospinal fluid of tuber-culous meningitis
patients using ELISA.
1) PPD-specific Ig G in CSF were significantly increased in tuberculous meningitis patients com-
pare to those of control and non-tuberculous menigitis patients.
2) PPD-specific Ig G in CSF were relatively increased in patients with pulmonary tuberculosis
compare to those in control group.
3) PPD-specific Ig G in serum were also increased and approximately the same level in patients
with pulmonary tuberculosis regardless of meningeal involvement. However, PPD-specific Ig G in
CSF were significantly increased in patients with meningitis compare to those in patients without
meningitis.
These results suggest that detecting PPD-specific Ig G in CSF using ELISA can be efficiently used
for diagnosis of tuberculous meningitis. The increment of PPD-specific Ig G in CSF may be due to
local production in central nervous system, and also in part a simple diffusion. Further studies will
be required. |
