Comparative assessment of T helper type 1 (Th1) cytokines and parasite load in post‐kala‐azar dermal leishmaniasis (PKDL). The levels of interferon (IFN)‐γ and tumour necrosis factor (TNF)‐α in culture supernatant upon total soluble Leishmania antigen (TSLA) stimulation of peripheral blood mononuclear cells (PBMCs) from patients with PKDL (n = 16) were measured by cytometric bead array (CBA) and parasite load in tissue lesions was determined by quantitative polymerase chain reaction (qPCR). Correlation was calculated by Spearman's rank correlation test. Diagonal line represents the best‐fitting line.
