title: Comparison of cytologic giemsa and real-time polymerase chain reaction technique for the diagnosis of cutaneous leishmaniasis on scraping smears.
abstract: OBJECTIVE
  To compare the results of real-time polymerase chain reaction (RT-PCR) for detection of Leishmania DNA in Giemsa-stained skin scraping slides with direct microscopic evaluation of Giemsa-stained skin scrapings and to estimate the sensitivity and specificity of RT-PCR.
  
  
  METHODS
  We used 30 samples from cases diagnosed with cutaneous leishmaniasis (CL), 16 from clinically suspected individuals but negative in direct microscopic evaluation and 50 normal individuals from nonendemic dry type CL areas.
  
  
  RESULTS
  All samples of CL positive and 8 of suspected cases were positive for RT-PCR, and all nonleishmaniasis cases were negative. The sensitivity and specificity of RT-PCR were 100% (95% CI 88-100%) and 88% (95% CI 78-95%), respectively. We also found an inverse association between the number of lympnocytes (OR = 0.90, 95% CI 0.83-0.97%), neutrophils and Leishman bodies.
