No results posted yet for this study

Summary

Intravesical BCG is the mainstay adjuvant management of high risk NMIBC. Adequacy of immune system stimulation is the determinant factor for patient response to BCG. Immunological markers for BCG-response could be helpful for urologists especially in the era of BCG shortage.

Objectives: To assess the predictive performance of different immunological markers on BCG-response in high risk NMIBC BCG-naïve patients.

Conditions

Interventions

DIAGNOSTIC_TEST

Urine ELISA for immunological markers (IL-2 and IL-10)

IL-2 and IL-10 levels were measured in the supernatants. Natural human-produced IL-2 and IL-10 concen¬trations were determined in the urine of all patients and controls by solid phase ELISA Quantikine IL-2 Immunoassay and IL-10 Immunoassay, respectively

DIAGNOSTIC_TEST

Reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) analysis

blood samples using QIAamp® RNA Blood Mini kit (QIAGEN, USA). 1 μg of total RNA was reverse transcribed with random primers, using High Capacity cDNA Archive Kit (Applied Biosystems, Foster City, CA, USA). RT-qPCR analysis was carried out with SYBER Green PCR Master Mix (Applied Biosystems, Foster City, CA, USA). Primers for TNF-α, CTLA4, T-bet+, GATA3+, FoxP3+ and GABDH as PCR control
