Frequncy and etiology of lymphadenopathy in Iranian HIV/AIDS patients

ABSTRACT

<p><b>OBJECTIVE</b>To estimate and outline the frequency and etiology of lymphadenopathy in HIV/AIDS patients.</p><p><b>METHODS</b>This study was conducted on 178 consecutive HIV/AIDS patient files for etiologies (categorized into three sub-groups definite, probable and possible) and associated factors of local and generalized lymphadenopathy.</p><p><b>RESULTS</b>Seventy-two (40.45%) patients including 63 male patients (87.5%) developed lymphadenopathy. HIV in lymphadenopathy(+) patients was most commonly transmitted intravenously (n=49). Generalized and localized lymphadenopathy respectively occurred in 27 (37.50%) and 45 (62.50%) patients, mainly in the cervical region (28.9% for local and 63% for generalized lymphadenopathy). The most common causes of lymphadenopathy were tuberculosis (n=24, 33.3%) and lymphoma (n=12, 16.6%). The frequency of lymphadenopathy was non-significantly higher in patients with AIDS (CD4 count <200 cell/µL) vs. HIV(+) patients (CD4 count >200 cell/µL).</p><p><b>CONCLUSIONS</b>Lymphadenopathy in HIV/AIDS patients may reflect a serious condition, most likely tuberculosis and lymphoma. Since patients might underestimate lymphadenopathy, physicians would rather list these entities for diagnosis.</p>
