Urinary tract infection analysis in a spinal cord injured population undergoing rehabilitation--how to treat?

STUDY DESIGN: Cross sectional study, including 38 outpatients. Standardized questionnaire was used and urine cultures were performed. OBJECTIVES: To study spinal cord-injured (SCI) patients bladder management, clinical aspects that symptomatic urinary tract infection (SUTI) may present and asymptomatic bacteriuria (AB) incidence with its antimicrobial susceptibility profile. SETTING: Spinal cord injury outpatient rehabilitation clinic. RESULTS: Clean intermittent catheterization is used by 71% of the patients. SUTI may have atypical clinical presentation (shivers, spasticity increase, headaches). In total, 65.7% (N=25) of the patients presented AB. Among these, the microorganisms isolated were resistant mainly to Ampicillin, Sulfamethoxazole-Trimethoprim and Norfloxacin, whose resistance rates were, respectively 73.3%, 60% and 33.3%. CONCLUSION: Special attention should be given to possible atypical symptoms for SUTI. Although a small amount of urine samples was analyzed, resistance rates against Ampicillin, Sulfamethoxazole-Trimethoprim, Ciprofloxacin and Nitrofurantoin appear to be higher among SCI patients compared to the general population, thus demonstrating the need for continuous monitoring of microorganisms susceptibility, in order to avoid therapeutic failure when dealing with this specific population.

Delayed graft function in renal transplant recipients: risk factors and impact on 1-year graft function: a single center analysis.

UNLABELLED: Delayed graft function (DGF), a frequent complication after kidney transplantation, occurs among about 60% of recipients of kidneys from deceased donors. DGF has a multifactorial etiology. It is characterized by acute tubular necrosis (ATN) upon biopsy. In this study we sought to identify among a group of recipients of kidneys from deceased donors, the incidence, risk factors, and impacts on patient and graft survivals of DGF. MATERIALS AND METHODS: We retrospectively analyzed medical records from renal transplant recipients aged >18 years who received a deceased donor kidney graft between January 2003 and December 2006. Kidneys lost during the first week posttransplantation were excluded from this series. RESULTS: Among 165 transplants, 111 (67%) displayed DGF, defined as the need for dialysis during the first week posttransplantation. The incidence of DGF was higher among patients with a cold ischemia time (CIT) > 24 hours: 85% vs 60%, DGF vs no DGF (P < .05), as well as for grafts from older donors. After 1-year follow-up, the DGF group showed worse graft function (serum creatinine 1.6 +/- 0.7 vs 1.3 +/- 0.4 mg/dL; P < .05) as well as a greater incidence of graft loss. CONCLUSION: Prolonged cold ischemia and older donor age were associated with a greater incidence of DGF in this series, leading to prolonged hospitalization, increased risk for an acute rejection episode, and reduced graft function and survival after 1 year.
