Tuberculosis is a major cause of mortality among AIDS patients in the developing world. The diagnosis of tuberculosis in HIV infected children is complicated by inefficient and expensive tuberculosis tests and vague diagnostic criteria. This study will evaluate the accuracy and efficiency of several different tuberculosis tests that could be used in developing countries.
HIV infection has been shown to increase mortality from tuberculosis (TB) fivefold in parts of Subsaharan Africa. Increasingly, HIV infected children in developing countries are becoming infected with Mycobacterium tuberculosis (Mtb) and dying at an early age. This project will evaluate novel approaches to the diagnosis of AIDS-related pediatric TB in a hyperendemic setting using rapid, cost-effective Mtb culture and susceptibility methods based on direct microscopic observation techniques. This study will utilize alternative noninvasive Mtb tests that are performed on nasopharyngeal aspirates (NPA) and stool. An optional component will assess improved rapid detection of Mtb by a semi-nested polymerase chain reaction assay (N2 PCR), a technique appropriate for regional reference laboratories in developing countries.
Two hundred-sixty children with clinically diagnosed pulmonary TB (including at least 100 HIV infected children) from the Hospital del Nino, Lima, Peru, and 260 age-matched controls will be enrolled in this study. Mtb will be detected in NPAs and stool by new and traditional culture methods and by N2 PCR. Gastric aspirates from children with a clinical diagnosis of TB will also be tested. Children with a positive N2 PCR but without clinical evidence of TB requiring antituberculous therapy will be followed longitudinally.

The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.
Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)
Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.
TUBERCULOSIS that involves any region of the GASTROINTESTINAL TRACT, mostly in the distal ILEUM and the CECUM. In most cases, MYCOBACTERIUM TUBERCULOSIS is the pathogen. Clinical features include ABDOMINAL PAIN; FEVER; and palpable mass in the ileocecal area.
