Signs and Symptoms
For PLWHIV the clinical presentation of active TB varies with CD4 count. In patients with high CD4 counts, pulmonary TB is the most common manifestation. The proportion of patients presenting with extrapulmonary TB increases with decreasing CD4 count.1,2
Active pulmonary TB may cause symptoms such as: 3,4
- a cough lasting 3 weeks or longer
- chest pain
- coughing up blood or sputum
- weakness or fatigue
- weight loss
- loss of appetite
- night sweats
- Early symptoms may be vague and could be unnoticed by the affected person4
Extrapulmonary TB is more common in PLWHIV, particularly as CD4 count decreases, compared with non HIV-infected individuals.1,2,5 Symptoms include constitutional symptoms such as fever, anorexia, weight loss, malaise and fatigue alongside the following:5,6
Lymph node TB:
- persistently swollen lymph nodes (usually nodes in the neck)
- discharge of fluid from swollen nodes through the skin
- arthralgia of the affected bone or joint
- curving of the affected bone or joint
- loss of articulation or sensation in the affected bone or joint
- weakened bone that may be prone to fracture
- abdominal pain
- anal bleeding
- aseptic pyuria
- painful urination (dysuria)
- groin pain
Central nervous system TB:
- stiff neck
- changes in mental state, e.g. confusion
- blurred vision
- fever (for several weeks)
- weight loss
- organ specific symptoms, although organ involvement is usually asymptomatic
Common extrapulmonary manifestations in PLWHIV
Presentations among PLWHIV co-infected with TB include:8
- pleural effusion
- pericardial disease
- miliary TB
- Many patients with extrapulmonary TB have coexistent pulmonary TB8
- In PLWHIV infected with TB, lymphadenopathy with multifocal involvement, intrathoracic and intraabdominal lymphadenopathy are more common than in TB patients not infected with HIV6
- Hepatobiliary and pancreatic TB are rare and occur more often in immunocompromised patients than in immunocompetent patients6
Isolated splenic tuberculosis is very rare in immunocompetent persons
- splenic tuberculosis can present as hypersplenism, splenic abscess, or as a solitary splenic lesion
- multiple splenic tuberculosis abscesses have been described in patients with HIV infection6
For further information on extrapulmonary TB, refer to this review from Sharma SK, Mohan A. (2004) Extrapulmonary tuberculosis.6
- Latent TB is asymptomatic, but PLWHIV who have latent TB are more likely to develop active TB than the general population.9,10
- Screening for TB in PLWHIV is critically important as latent TB infection can be managed with isoniazid preventive therapy.11
