ObjectivesTo define the frequency of cytomegalovirus disease among kidney transplant
patients in an intensive care unit in which this complication was suspected
and to identify predisposing factors and their possible impact on clinical
outcome.MethodsRetrospective observational study in which kidney transplant patients over
the age of 18 years were hospitalized for any reason in an intensive care
unit with at least one collection of samples to test for the presence of
antigenemia or cytomegalovirus via polymerase chain reaction during
hospitalization. Cytomegalovirus disease was defined as positive antigenemia
or polymerase chain reaction above 500 copies/mL in the presence of symptoms
and in the appropriate clinical setting, as judged by the attending
physician.ResultsA total of 99 patients were included (age: 53.4 ± 12.8 years, 71.6%
male). Cytomegalovirus disease was diagnosed in 39 patients (39.4%).
Respiratory symptoms (51%), non-specific clinical worsening (20%) or
gastrointestinal symptoms (14%) were the main reasons for exam collection.
Transplant time was lower in those with cytomegalovirus disease than in
those without this diagnosis (6.5 months and 31.2 months, p = 0.001), along
with pulse therapy in the last 6 months (41% and 16.9%, p = 0.008) and
previous use of thymoglobulin in the last year (35.9% and 6.8%, p <
0.001). In the logistic regression model, only the transplant time and the
use of thymoglobulin were associated with a higher frequency of
cytomegalovirus. There was no difference in clinical evolution between
patients with and without cytomegalovirus disease.ConclusionIn kidney transplant patients suspected of cytomegalovirus disease, the
prevalence was high. Transplant time less than 6 months, and the use of
thymoglobulin in the last year should increase the intensivist's suspicion
for this complication.
