| Resumo: | Cytomegalovirus infection is an important complication after renal transplantation.
The use of immunosuppressants in the prevention of rejection may trigger changes in
the behavior of CMV, it is important to post-transplant viral follow-up, as preventive
measure, to limit clinical impact of this vírus. The objective of this study was to
monitor cytomegalovirus infection in patients who underwent renal transplant in the
Onofre Lopes University Hospital (HUOL), Natal, Rio Grande do Norte. In total were
included 165 patients in the period from 2013 to 2016. Samples of peripheral blood
obtained on the 2nd, 4th, 8th, 12th and 24th weeks post-transplant to molecular
detection of CMV by nested-PCR and quantification of CMV viral load by real-time
PCR. Who renal transplants presented incidence of 59.4% of active CMV infection
was, correlation with the use of everolimus (p = 0.0008) and thymoglobulin (p =
0.0042). Forty-five patients who presented copy numbers above the cut-off point
(4600 copies/mL), with sensitivity of 67.2% and specificity of 70.7%, associated were
clinical signs and symptoms of CMV infection, such as fever, gastrointestinal
disturbance, myalgia, leukopenia and thrombocytopenia. Our results demonstrated a
high incidence of active CMV infection, evidencing the necessity of the early
diagnosis of this infection, in addition to real-time PCR can be using to monitor CMV
symptomatic infections in renal transplant recipients. |
