Clinical features of HIV seropositive and HIV seronegative patients with tuberculous lymphadenitis in Dar es Salaam.
METHODS
The medical wards of a referral hospital in Dar es Salaam, Tanzania.


OBJECTIVE
To investigate the impact of HIV infection on clinical features in tuberculous lymphadenitis.


METHODS
A prospective clinical study of HIV seropositive and HIV seronegative patients with lymphadenopathy.


RESULTS
Of 128 patients with peripheral lymphadenopathy, 24 had no tuberculosis (TB) and in 10 patients TB was found only in other organs. The remaining 94 patients, of whom 76% were HIV seropositive, formed our study population. TB lymphadenitis was considered proven in 89 and probable in 5 patients. Disseminated TB (both TB adenitis and TB in other organs) was diagnosed more often in HIV seropositive than in HIV seronegative patients (52% versus 26%, P < 0.03). 59% of the 71 HIV-infected patients compared to only 4% of the 23 patients without HIV infection were over 30 years of age (P < 0.02). The following clinical features were significantly associated with HIV infection: dyspnoea, respiratory rate > 20/min, low motility score (bedridden), neurological abnormalities, hepatomegaly, splenomegaly, lymph node size < 2.5 cm, negative PPD skin test, lymphopenia (< 1000/cm3) and presence of pleural fluid.


CONCLUSIONS
Co-infection with HIV influences several clinical and laboratory features in patients with tuberculous lymphadenitis.
