PPD skin reactivity and anergy in HIV-infected patients in Hawaii.
نویسندگان
چکیده
This study was a prospective screening study for PPD and anergy skin test reactivity in 304 HIV-positive individuals. A PPD positivity rate of 4.1% and an anergy rate of 50.5% were observed. The Hawaii HIV population has a relatively low prevalence of latent TB compared with the high prevalence of TB in the Hawaii population at large.

Antigen-specific and persistent tuberculin anergy in a cohort of pulmonary tuberculosis patients from rural Cambodia.
Purified protein derivative (PPD) skin testing is used to identify persons infected with Mycobacterium tuberculosis (Mtb) and to assess cell-mediated immune responses to Mtb. However, lack of skin induration to intradermal injection of PPD or PPD anergy is observed in a subset of patients with active tuberculosis (TB). To investigate the sensitivity and persistence of PPD reactivity and its in ...
متن کاملDelayed-type hypersensitivity skin test responses to PPD and other antigens among BCG-vaccinated HIV-1-infected and healthy children and adolescents.
INTRODUCTION Among HIV-1-infected patients, CD4+ T cell counts are well-established markers of cell-mediated immunity. Delayed-type hypersensitivity (DTH) skin tests can be used to evaluate in vivo cell-mediated immunity to common antigens. METHODS DTH responses to tuberculin purified protein derivative (PPD), sporotrichin, trichophytin, candidin and streptokinase/streptodornase antigens were...

INH preventive therapy (IPT) has been shown in several randomized controlled trials to reduce the risk of developing active TB in tuberculin skin test (TST) or purified protein derivative (PPD) positive HIV infected individuals. Detection of latent tuberculosis by TST and determination of factors associated with the PPD positivity in HIV-infected persons are important for the targeting of chemo...

BACKGROUND The objective of this study was to determine the frequency of positive purified protein derivative (PPD) skin test in those infected with human immunodeficiency virus (HIV) and to investigate its association with CD4-positive T cell count, demographic factors, and possible routes of transmission in Iran. METHODS Fifty-one (36 males and 15 females) patients from an HIV clinic were s...
متن کاملAnergy in active pulmonary tuberculosis. A comparison between positive and negative reactors and an evaluation of 5 TU and 250 TU skin test doses.
Based on induration of less than 10 mm at 48 and 72 hours, 49 of 200 (25 percent) patients with active pulmonary tuberculosis failed to respond to intermediate (5TU) strength PPD. Distribution of reactors vs nonreactors was similar with regard to sex but not race, with more white subjects proving to be nonreactive. Additional comparisons between the two groups revealed significantly higher valu...
