RT-PCR on Urine Samples: Added Value for the Diagnosis of Chikungunya Virus Infection

CHIK_urine
Start date: March 2016
Phase: N/A
Study type: Observational [Patient Registry]

Retrospective laboratory evaluation of the detection rate of CHIKV infection by real-time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) on urine. Urine and serum samples from patients with confirmed CHIKV infections from an endemic area (Aruba) and from ITM will be analyzed. The results will be evaluated on a case-by-case basis: time since onset, patient characteristics, severity of symptoms, serology results. The positivity in-time of CHIKV RNA in urine will be evaluated in comparison with viremia. Patients with suspected acute CHIKV infection will be asked (by written informed consent; annex 1) to provide urine samples within 72 hours after onset of disease, followed by urine samples on day 7, day 10, day 14 and three urine samples 3, 4 and 12 weeks after onset. They will be asked to provide serum samples within 72 hours after onset of disease, followed by serum samples on day 7, day 10, day 14. In total, twenty patients with an initial positive result of CHIKV RT-PCR on serum will be included for follow-up. The number of urine samples that will be tested is 140.
