Dengue Virus Infection in Solid Organ Transplant Recipients: A Case Series and Literature Review

Abstract

Dengue fever is the most prevalent arbovirus infection among humans, and tropical regions are hyperendemic for this infection. The number of solid organ transplant recipients is continuously increasing, and there are few data regarding the clinical course and outcomes of dengue infection among this population. We report on a retrospective case series of solid organ transplant recipients with dengue virus infection from 2001 to 2018 at Fundación Valle del Lili in Cali, Colombia. A total of 20 patients were included. The median age was 50.5 years (interquartile range [IQR] = 31-63.5 years) and 65% were female. Regarding the clinical course, 75% of patients had at least one warning sign, 45% were managed in the intensive care unit, and 30% had severe dengue. The median of time from transplant and dengue infection was 27.6 months (IQR = 3.82-59.12 months), and three patients had the disease in the first month after the transplant. All patients were discharged, and none of them had graft rejection. Dengue is an endemic disease in our region and represents a threat among solid organ transplantation recipients. All patients had a full recovery after the infection, suggesting that timely and effective management of patients and the access to high-complexity services could prevent fatal cases.
