Acid phosphatase activity of cerebrospinal fluid cells in bacterial and abacterial meningitis
Abstract:
Acid phosphatase staining is performed on cerebrospinal fluid cells of 365 samples from 105 patients with various types of meningitis. This enzyme activity is strongly positive in the early samples of bacterial meningitis, as far as the patients had not received a pretreatment with antibiotics for more than 24 h. It allows monitoring the response to therapy in subsequent samples. Acid phosphatase activity is positive in 2 cases of cryptococcus meningitis. It is negative in all cases of aseptic and Mycoplasma pneumoniae meningitis. The results in herpes encephalitis are variable, depending on the clinical state and the degree of brain destruction. Acid phosphatase staining is a useful and rapid cytological technique for determination of the nature of the meningitis and for monitoring the therapeutical response.
Insights
Acid phosphatase staining is a rapid diagnostic tool for meningitis. It helps differentiate bacterial meningitis and monitor treatment effectiveness in cerebrospinal fluid samples.
Area of Science:
- Neurology
- Clinical Chemistry
- Cytopathology
Background:
- Meningitis diagnosis can be challenging, requiring timely and accurate methods.
- Cerebrospinal fluid (CSF) analysis is crucial for identifying the causative agent of meningitis.
- Acid phosphatase (ACP) is an enzyme with potential diagnostic value in infectious diseases.
Purpose of the Study:
- To evaluate the utility of acid phosphatase staining in CSF for diagnosing various types of meningitis.
- To assess the correlation between acid phosphatase activity and the type and stage of meningitis.
- To determine if acid phosphatase staining can aid in monitoring therapeutic response.
Main Methods:
- Acid phosphatase staining was performed on 365 CSF samples from 105 patients with diverse meningitis types.
- CSF samples were analyzed for enzyme activity.
- Clinical data, including antibiotic pretreatment and patient condition, were correlated with staining results.
Main Results:
- Strongly positive acid phosphatase activity was observed in early bacterial meningitis samples (untreated >24h).
- Positive results were noted in two cases of cryptococcal meningitis.
- Acid phosphatase staining was negative in aseptic and Mycoplasma pneumoniae meningitis.
- Results for herpes encephalitis were variable, linked to clinical status and brain damage.
Conclusions:
- Acid phosphatase staining is a valuable and rapid cytological method for determining meningitis type.
- This technique aids in monitoring the effectiveness of meningitis treatment.
- Acid phosphatase activity in CSF offers differential diagnostic insights for meningitis.
