Diagnosis of post-kala-azar dermal leishmaniasis (PKDL), particularly the macular form, is difficult when based on microscopy. This study compared the results of nested PCR (91.9% positive samples) with imprint smear microscopy (70.9% positive samples) for 62 PKDL samples. We found that nested PCR, which indicated 87.5% positivity for the macular lesions, compared to 41.6% positivity by imprint smear microscopy, is an efficient method for early diagnosis of PKDL.
内脏利什曼病后皮肤利什曼病(PKDL),尤其是斑疹型的诊断,基于显微镜检查时存在困难。本研究比较了62份PKDL样本的巢式PCR(阳性样本91.9%)与印片涂片显微镜检查(阳性样本70.9%)的结果。我们发现,巢式PCR对斑疹性病变的阳性率为87.5%,而印片涂片显微镜检查的阳性率为41.6%,巢式PCR是PKDL早期诊断的有效方法。
