The human immunodeficiency virus (HIV) epidemic is associated with a marked increase of tuberculosis cases. The influence of HIV on diagnostic methods for tuberculous lymphadenitis is less clear. In an environment of high HIV and tuberculosis prevalence in Blantyre, Malawi, a prospective study compared results of basic procedures diagnosing tuberculous lymphadenitis with the outcome of histology and/or culture. One hundred out-patients, aged 15-55 years, with extra-inguinal lymphadenopathy not responding to general antibiotics, entered the study. Among 52 cases, with whom all procedures were carried out in accordance with the protocol, 38 (73%) were diagnosed as tuberculous lymphadenitis; 84% of the latter (32/38) were seropositive for HIV. Needle aspirate and biopsy smears stained by the Ziehl-Neelsen technique contributed little to detecting tuberculosis, 8% and 11% respectively. In contrast, macroscopic caseation of excised lymph nodes showed a high yield of 82%, which was similar to histology, and higher than that of Löwenstein-Jensen culture (61%). The study suggested that HIV positivity of tuberculous lymphadenitis patients decreased the possibility of histology and culture both being indicative of tuberculosis (odds ratio 0.10; P = 0.06). Consequently histology results, often used as the single definitive method, failed to diagnose 18% (7/38) of tuberculosis cases. However, it was reassuring that 4 simple methods, which can safely be carried out at district level, could be expected to diagnose 80-95% of tuberculous lymphadenitis cases in a timely and cost-effective manner.

PIP: A prospective study conducted in 1994-95 in Blantyre, Malawi, investigated the influence of HIV on diagnostic methods for tuberculous lymphadenitis in 100 outpatients 15-55 years old with extra-inguinal lymphadenopathy not responsive to general antibiotics. For the 52 cases for which all diagnostic procedures were carried out, 38 (73%) were diagnosed as tuberculous lymphadenitis; 32 (84%) of these patients were HIV-positive. Needle aspirate and biopsy smears stained by the Ziehl-Neelsen technique contributed only 8% and 11%, respectively, to detecting tuberculosis. In contrast, macroscopic caseation of excised lymph nodes, histology, and Lowenstein-Jensen culture had yields of 82%, 82%, and 61%, respectively. These findings indicate that, in tuberculous lymphadenitis patients, HIV infection decreases the diagnostic power of culture and histology. However, use of the other methods can diagnose 80-95% of tuberculous lymphadenitis cases in a cost-effective manner in areas with high prevalences of both HIV and tuberculosis.
