 Abstract | | |
The incidence of infection is significantly elevated in renal transplant recipients,but native kidney infection is an uncommon event in these patients. We describe a 52-year-old renal transplant recipient with infection of the native kidneys that had atypical clinical presentation and a unusual course. Keywords: Renal transplantation, Urinary tract infections, Mixed infections

| Introduction | |  |
Incidence of infection is significantly higher in renal transplant recipients than general population. transplant recipients have several defects in immune system that result in decreased host resistance to infection. [1] Urinary tract infections (UTIs) are the most common bacterial infections that occur in renal transplant recipients, particularly in the first few months post transplant. [2] However, native kidney infection occurs rarely and this may mislead the physician mostly because of their little role in urine production. 1 Moreover, due to low glomerular filtration and renal uptake of the native kidneys, interpretation of diagnostic methods such as radionuclide methods is difficult. [3]
We present a renal transplant recipient patient with prolonged fever complicated consecutive infections with different etiology and unusual source.
| Case Report | | |
A 52-year-old man suffered from chronic renal failure (CRF) of unknown etiology and had been maintained on hemodialysis therapy for five years before he received a living unrelated kidney transplant. He complained of fever and malaise without any other problem.
On physical examination the patient's oral temperature was 38.5°C, the transplanted kidney, urine output, and other systems were unremarkable. The chest x-ray and laboratory findings including urinalysis, BUN, and serum creatinine were within normal limits. Blood and urine cultures were negative [Table 1]. The titer of CMV IgM antibody was elevated and PCR study of CMV antigen revealed positive particles. Ultrasonography revealed small multicystic native kidneys and normal allograft.
The patient was originally on triple immuno-suppressive therapy that included cyclosporine 100 mg twice daily, azathioprine 50 mg daily, and prednisolone 5 mg daily. Azathioprine was discontinued and empiric intravenous gancyclovir was initiated and continued for 1 month. The fever subsided within 5 days and oral preparation of the drug was administered for the following two months.
The patient was discharged with good general condition on outpatient clinic visit at the end of the first month. However, after 2 months, the patient was referred again for severe fever and shaking chill. On physical exam, he looked toxic and ill with oral temperature of 39°C. Blood and urine cultures and CMV antigen and antibody assays were requested, and empiric broad spectrum antibiotic therapy was initiated. The cultures were negative, and the CMV assays were within normal limits. Unfortunately, the patient remained febrile despite the administration of broad spectrum antibiotics, and even after modifying them. The bone marrow culture was also negative and repeated ultrasonography showed the same findings as the previous one.
The renal function tests remained normal during hospitalization. A Gallium-67 citrate scan revealed low uptake of gallium in lower and posterior portions of the liver, which had normal size and function.
Overall, with these findings we concluded that the right small native kidney might be infected as an occult site of infection. The patient was scheduled for urgent surgical exploration, which revealed a severely infected right kidney and was excised. Two days after the surgical resection, the patient expired because of severe septicemia.
| Discussion | | |
Infection remains a significant cause of morbidity and mortality in renal transplant recipients. [4] However, infections in patients with long-term successful allografts are typically similar to those that develop in the general population. [5]
Factors that confound the diagnosis of infection in the renal recipient include delays in clinical diagnosis due to modified clinical and radiological signs in the immunocompromised hosts, multiple antibiotic courses, inherent diagnostic uncertainty due to a preceding CMV infection, and involvement of extra-allograft sites, [6] as what happened in our patient who developed infection in the native kidneys. In renal recipient patients, infections of the native kidneys occur rarely because of low renal blood flow, renal fibrosis, and low urine output unless urine stasis is detected such as in cysts similar to this patient, [7] who also suffered from a recent and prolonged CMV infection that was another predisposing factor.
The diagnosis of infection in the native kidney was complicated because of the low kidney uptake of gallium and the need for nephrectomy, which was a high risk surgical operation in an ill patient with probable eventual loss of the transplanted kidney. Moreover, the late diagnosis of the source of infection may result in a prolonged recovery period and antibiotic resistance. UTIs developing more than three to six months post transplant, are considered more benign than early ones. [8] How-ever, some evidence suggests that late UTIs are not necessarily benign and may be associated with an increased risk of mortality as was found in one large retrospective cohort study. [9]
