Extrapulmonary Tuberculosis

Abstract

rom 1985 until 1992 there was a resurgence of tuberculosis in the United States that coincided with the epidemic of acquired immunodeficiency syndrome (AIDS). 1 Although the U.S. incidence of tuberculosis has since been in decline, this disease remains a major problem for much of the world, with a global prevalence of infection estimated at 32 percent. 2 Thus, the percentage of U.S. cases that occur among foreign-born persons is increasing (53 percent in 2003). 1 Extrapulmonary tuberculosis has become more common since the advent of human immunodeficiency virus (HIV) infection. 3 Extrapulmonary Tuberculosis and HIV Infection Extrapulmonary involvement can be seen in more than 50 percent of patients with concurrent AIDS and tuberculosis. 3-5 The risk of extrapulmonary tuberculosis and mycobacteremia increases with advancing immunosuppression. 6 Unique features of AIDS-associated tuberculosis include extra

“…Twenty-three lymph node aspirates and one body fluid specimens were also smear positive with Ziehl Neelsen staining technique. The cytological result of the current study was higher than the other studies conducted in Saudi Arabia (42.9%) and Ethiopia (39.7%) [26,27]. …”

“…Previously, age was reported as an independent risk factor for EPTB infection in high-burden countries [26,32,33]. This is consistent with other studies in San Francisco, Saudi Arabia, India and Tanzania which showed that high prevalence of EPTB among productive age groups [26,28,30,34].…”

“…Previously, age was reported as an independent risk factor for EPTB infection in high-burden countries [26,32,33]. This is consistent with other studies in San Francisco, Saudi Arabia, India and Tanzania which showed that high prevalence of EPTB among productive age groups [26,28,30,34]. Most of tuberculosis cases in this population might be largely related to ongoing tuberculosis transmission, given that the associated age group (31–40 years) is known as the most unstable and high risk group for TB transmission.…”
