Abstract

Objective:

To evaluate the diagnostic value of serum cryptococcal capsular polysaccharide antigen latex agglutination test (LA) for pulmonary cryptococcosis.

Methods:

Serum and lung biopsy specimens of 27 patients, who were suspected of having pulmonary cryptococcosis based on clinical presentations and imaging features, were collected from July 2000 to July 2007 in the First Hospital of Peking University. LA test and histopathological examination were performed in all the patients.

Results:

Histopathological examination confirmed pulmonary cryptococcosis in 9 cases, all of whom were positive for serum LA test. The other 18 cases were confirmed to have no cryptococcosis and all of them were negative for serum LA test. Therefore, the sensitivity and specificity of LA test were both 100%.

Conclusion:

The diagnostic value of serum LA test for pulmonary cryptococcosis is high.

Cryptococcal Meningitis

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
