RESUMO

Purpose: This is a secondary analysis examining a six-month home-based Prostate Cancer-Patient Empowerment Program (PC-PEP) on patient-reported urinary, bowel, sexual, and hormonal function in men with curative prostate cancer (PC) against standard of care. Methods: In a crossover clinical trial, 128 men scheduled for PC surgery (n = 62) or radiotherapy with/without hormones (n = 66) were randomized to PC-PEP (n = 66) or waitlist-control and received the standard of care for 6 months, and then PC-PEP to the end of the year. PC-PEP included daily emails with video instructions, aerobic and strength training, dietary guidance, stress management, and social support, with an initial PFMT nurse consultation. Over 6 months, participants in the PC-PEP received optional text alerts (up to three times daily) reminding them to follow the PFMT video program, encompassing relaxation, quick-twitch, and endurance exercises; compliance was assessed weekly. Participants completed baseline, 6, and 12-month International Prostate Symptom Score (IPSS) and Expanded Prostate Cancer Index Composite (EPIC) questionnaires. Results: At 6 months, men in the PC-PEP reported improved urinary bother (IPSS, p = 0.004), continence (EPIC, p < 0.001), and irritation/obstruction function (p = 0.008) compared to controls, with sustained urinary continence benefits at 12 months (p = 0.002). Surgery patients in the waitlist-control group had 3.5 (95% CI: 1.2, 10, p = 0.024) times and 2.3 (95% CI: 0.82, 6.7, p = 0.11) times higher odds of moderate to severe urinary problems compared to PC-PEP at 6 and 12 months, respectively. Conclusions: PC-PEP significantly improves lower urinary tract symptoms, affirming its suitability for clinical integration alongside established mental health benefits in men with curative prostate cancer.

RESUMO

BACKGROUND: Although survival rates for newly diagnosed prostate cancer patients are very high, most of them will likely suffer significant treatment-related side effects, depression, or anxiety, affecting their quality of life. OBJECTIVE: The aim of this study was to examine the effects of a 6-mo online home-based physical, mental, and social support intervention, the Prostate Cancer Patient Empowerment Program (PC-PEP), on preventing psychological distress among men undergoing curative prostate cancer treatment. DESIGN, SETTING, AND PARTICIPANTS: In a crossover randomized clinical trial of 128 men aged 50-82 yr scheduled for curative prostate cancer surgery or radiotherapy (± hormone treatment), 66 received the 6-mo PC-PEP intervention and 62 were randomized to a waitlist-control arm and received the standard of care for 6 mo, and then PC-PEP to the end of the year. The PC-PEP intervention consisted of daily e-mails with video instructions providing education, patient activation, and empowerment on healthy living including physical and mental health, dietary recommendations, social support, physical and pelvic floor fitness, stress reduction using a biofeedback device, social connection and intimacy, and social support. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was nonspecific psychological distress (clinical cutoff ≥20) measured at baseline, and at 6 and 12 mo using the Kessler Psychological Distress Scale (K10). RESULTS AND LIMITATIONS: At 6 mo, patients in the waitlist-control group had 3.59 (95% confidence interval: 1.12-11.51) times higher odds for nonspecific psychological distress and need for psychological treatment than men who received the PC-PEP intervention. At 12 mo, the wait-list control group that received the intervention at 6 mo had higher psychological distress than the early group. CONCLUSIONS: PC-PEP delivered early following diagnosis significantly prevented the burden of psychological distress in men undergoing curative prostate cancer treatment compared with standard of care, or late (6 mo later) intervention. PATIENT SUMMARY: In this report, we looked at the effectiveness of a program (Prostate Cancer Patient Empowerment Program: PC-PEP) developed with patients' engagement on the mental distress of patients awaiting curative treatment for their prostate cancer. The PC-PEP program lasted for 6 mo, and it prescribed, described, and demonstrated daily aerobic and strength training, kegels (pelvic floor training to help with urinary and sexual function), dietary changes that have been shown to be helpful in the prevention of prostate cancer and prostate cancer progression, stress reduction using a biofeedback device, as well as social and emotional support. All patients in the PC-PEP program were invited to a monthly video conference with the leads of the program who appeared in the 6 mo of daily videos prescribing the activities the patients were asked to watch and follow. The leads were a prostate cancer oncologist and a scientist in prostate cancer quality of life research. Half of the patients in this study received PC-PEP daily for the first 6 mo and were re-assessed at the end of the year. The other half received standard of care for 6 month and then received the intervention to the end of the year. The results of the study show that, at 6 mo, this intervention was effective at reducing the mental distress that accompanies a prostate cancer diagnosis and treatment compared with the standard of care. Mental distress was significantly reduced when the intervention was received early, compared with that received late (6 mo after scheduled curative treatment). We conclude that multi-faceted patient education and empowerment programming of this kind that is developed with patient engagement from the start is crucial to the care of patients diagnosed with prostate cancer and should be implemented in the standard of care. While treatment for prostate cancer is highly successful, side effects that accompany most treatments significantly affect the quality of life of patients. Here, we describe PC-PEP, a patient education and activation program that is cost effective, highly enforced by patients, and successful at reducing the impact of prostate cancer active treatment-related side effects on their psychological state.

The program is now being tested in a phase 4 implementation trial throughout Canada and internationally (New Zealand), and is being expanded and tested for other types of cancer.

RESUMO

OBJECTIVE: With a prolonged natural history compared with many other cancers, prostate cancer patients have high rates of mental illness over the duration of their treatment. Here, we examine the relationship between personality and mental health distress in a sample of prostate cancer patients. METHODS: This study was conducted in the Canadian Maritime provinces, where a cohort of 189 men with prostate cancer were invited to complete a quality-of-life online survey between May 2017 and December 2019. The presence or absence of screening positive for mental health illness was the primary outcome and was assessed using Kessler's 10-item scale (K10). Urinary symptoms were assessed using the International Prostate Symptom Score (IPSS). The ten-item personality inventory (TIPI) assessed extraversion, agreeableness, conscientiousness, emotional stability (or neuroticism), and openness to experiences. A multivariate logistic regression model was created to examine the association between personality, urinary symptoms, and mental health distress, while controlling for time from diagnosis, treatment type, age, and multimorbidity. RESULTS: Screening positive for mental illness (18.0%) was associated with personality traits of low levels of emotional stability (OR = 0.07, 95% CI: 0.03-0.20) and moderate to severe urinary problems (OR = 5.21, 95% CI: 1.94-14.05)). There was no identified association between treatment received for prostate cancer and personality type. CONCLUSION: Screening for mental health illness in this population may help reduce morbidity associated with cancer treatment, as well as identify patients who may be at risk of mental health distress and could benefit from individualized mental health support services. These findings suggest that multidisciplinary care is essential for the management of these patients.

RESUMO

Recent reviews and observational studies have reported that patients with prostate cancer (PCa) are at increased risk of mental health issues, which in turn negatively affects oncological outcomes. Here, we examine possible explanatory variables of mental distress in a population-based cohort of men who have undergone radical prostatectomy (RP). Data were derived from a Maritimes-Canada online survey assessing patient-reported quality of life outcomes between 2017 and 2019 administered to 136 men (47-88 years old, currently in a relationship) who have undergone RP for their PCa diagnosis. The primary outcome was a validated assessment of mental distress, the Kessler Psychological Distress Scale (K10). Urinary function was assessed using the International Prostate Symptom Score, and relationship satisfaction was assessed using the Dyadic Assessment Scale. A multivariate logistic regression assessed the contribution of urinary function, relationship satisfaction, age, multimorbidity, additional treatments, medication for depression and/or anxiety, and survivorship time. A total of 16.2% men in this sample screened positive for mental distress. The severity of urinary problems was positively associated with increased mental distress (OR = 4.79, 95% CI [1.04, 22.03]), while increased age (OR = 0.87, 95% CI [0.78, 0.97]), relationship satisfaction (OR = 0.14, 95% CI [0.3, .077]), and current medication for anxiety, depression, or both (OR = 0.09, 95% CI [0.02, 0.62]) were protective factors. Survivorship time, the presence of additional comorbidities, or PCa treatments were not identified to be statistically significant contributions to the fitted model. Here, we report that RP survivors are prone to presenting with increased mental distress long after treatment. Screening for mental distress during RP survivorship is recommended.

RESUMO

INTRODUCTION: Although survival rates are highest among prostate cancer survivors compared to any other forms of cancer, nearly 60% suffer from mental distress. Here we examine urinary function and psychosocial stressors and their association with poor mental health in a younger group of prostate cancer survivors who have undergone curative treatment. METHODS: The study includes 128 men (47 to 70 years old) who received active treatment for prostate cancer, and completed a survivorship online survey between 2017 and 2018. Psychological distress was assessed with Kessler Psychological Distress Scale. International Prostate Symptom Score subscales (incomplete urinary emptying, frequency, intermittency, urgency, weak stream, straining and nocturia) and number of current prostate cancer survivorship stressors were predictors. Multivariate logistic regression was used to fit the model while controlling for months of survivorship since diagnosis, the presence or absence of surgery, radiation or hormone therapy treatment, current medication for depression and demographics. RESULTS: A total of 19.5% of men scored positive for current mental health issues. Prostate cancer survivors who reported increased number of current survivorship stressors (OR 1.48, 95% CI 1.09-2.01), had higher frequency of urination (OR 2.05, 95% CI 1.15-3.64), history of radiation treatment (OR 7.15, 95% CI 1.02-50.35) and were currently on prescribed medication for depression (OR 33.47, 95% CI 3.80-294.87) had higher odds for screening positive for psychological distress compared with their counterparts. CONCLUSIONS: These results corroborate recent findings showing an intersection between urological oncology and poor mental health during survivorship, and warrant the development of multidisciplinary teams in addressing survivorship issues in this population.

RESUMO

The vertebral, anal, cardiac, tracheoesophageal, renal, and limb birth defects (VACTERL) association is a rare, non-random constellation of congenital abnormalities among which urinary tract anomalies can be included. In the presence of these anomalies, patients are suspected to have a higher rate of renal failure than average. We report a case of a 22-year-old woman with VACTERL association and consequent end stage renal failure. A live-related kidney transplant was carried out successfully and the postoperative course was uncomplicated. The patient had immediate graft function. Risk factors that may complicate kidney transplant surgery in this patient population as well as considerations relevant to peritransplant management are discussed.

RESUMO

INTRODUCTION: To develop a classification tree for the preoperative prediction of benign versus malignant disease in patients with small renal masses. MATERIALS AND METHODS: This is a retrospective study including 395 consecutive patients who underwent surgical treatment for a renal mass < 5 cm in maximum diameter between July 1st 2001 and June 30th 2010. A classification tree to predict the risk of having a benign renal mass preoperatively was developed using recursive partitioning analysis for repeated measures outcomes. Age, sex, volume on preoperative imaging, tumor location (central/peripheral), degree of endophytic component (1%-100%), and tumor axis position were used as potential predictors to develop the model. RESULTS: Forty-five patients (11.4%) were found to have a benign mass postoperatively. A classification tree has been developed which can predict the risk of benign disease with an accuracy of 88.9% (95% CI: 85.3 to 91.8). The significant prognostic factors in the classification tree are tumor volume, degree of endophytic component and symptoms at diagnosis. As an example of its utilization, a renal mass with a volume of < 5.67 cm3 that is < 45% endophytic has a 52.6% chance of having benign pathology. Conversely, a renal mass with a volume ≥ 5.67 cm3 that is ≥ 35% endophytic has only a 5.3% possibility of being benign. CONCLUSIONS: A classification tree to predict the risk of benign disease in small renal masses has been developed to aid the clinician when deciding on treatment strategies for small renal masses.

RESUMO

Intestinal type villous adenomas are uncommon in the genitourinary tract. Most reported cases have been located in the urinary bladder or urachus. Villous adenoma arising in the renal pelvis or ureter is very rare. We present a case of an 81-year-old female who presented with difficulty voiding and mucosuria. A computed tomography scan identified right-sided hydronephrosis, renal parenchymal atrophy, nonobstructing calculi and a lower pole renal mass. She underwent open right nephrectomy. Histopathologic examination of the kidney revealed an intestinal type villous adenoma of the renal pelvis with high-grade dysplasia and focal areas suspicious for invasive adenocarcinoma. We review the four previously reported cases of intestinal type villous adenoma in the renal pelvis and discuss diagnosis and management of this unusual neoplasm.

RESUMO

BACKGROUND: Most studies have found cold ischemic time to be an important predictor of delayed graft function in kidney transplantation. Relatively less is known about the warm time associated with vascular anastomosis and early outcomes. METHODS: A retrospective cohort of 298 consecutive solitary deceased donor kidney recipients from January 2006 to August 2012 was analyzed to examine the association between anastomosis time and delayed graft function (need for dialysis) and length of hospital stay. RESULTS: Delayed graft function (DGF) was observed in 56 patients (18.8%). The median anastomosis time was 30 minutes (interquartile range 24, 45 minutes). Anastomosis time was independently associated with DGF in a multivariable, binary logistic regression analysis (odds Ratio (OR) 1.037 per minute, 95% CI 1.016, 1.057, P = 0.001). An anastomosis time >29 minutes was also associated with a 3.5 fold higher (OR 3.5, 95% CI 1.6, 7.3, P = 0.001) risk of DGF. Median days in hospital was 9 (interquartile range 7, 14 days). Every 5 minutes of longer anastomosis time (0.20 days per minute, 95% CI 0.13, 0.27, P <0.001) was associated with 1 extra day in hospital in a multivariable linear regression model. An anastomosis time >29 minutes was associated with 3.8 (95% CI 1.6, 6.0, P <0.001) more days in hospital. CONCLUSION: Anastomosis time may be an underappreciated but modifiable variable in dictating use of hospital resources. The impact of anastomosis time on longer term outcomes deserves further study.

RESUMO

BACKGROUND: Given the unpredictable timing of deceased donor organs and the need for blood transfusion, this study was carried out to determine the rate and risk factors for transfusion in order to identifying a low-risk cohort in the face of a critical blood shortage. METHODS: This retrospective chart review examined 306 consecutive deceased solitary kidney transplant recipients from January 2006 to August 2012. RESULTS: Records show that 80 (26.1%) patients were transfused with a total of 300 units (0.98 units/transplant) during their first hospital stay. Transfusions were higher in patients on warfarin (8/14, 57%, 5.1 units/transplant) and antiplatelet agents (46/136, 33.8%, 1.1 unit/transplant) compared to no anticoagulants (74/156, 16.7%, 0.47 units/transplant). In a multivariable logistic regression analysis warfarin (odd ratio (OR) 8.2, 95% confidence interval (CI) 2.5-27, P=0.001), antiplatelet agents (OR 2.9, 95% CI 1.6-5.3, P=0.001), recipient age ≥55 years (OR 2.2, 95% CI 1.2-3.9, P=0.008), recipient male (OR 0.36, 95% CI 0.2-0.64, P=0.001) and preop hemoglobin ≥115 g/L (OR 0.32, 95% CI 0.18-0.57, P<0.001) were independent predictors of blood transfusion. Lower bleeding cohorts with transfusion rates <5% could not be identified. CONCLUSION: The need for blood is significantly higher in subjects on either warfarin or antiplatelet agents. These patients might be avoided if kidney transplantation is to occur during a critical blood shortage. Unfortunately even patients not on anticoagulation are at some risk.

RESUMO

BACKGROUND: Studies have shown that achieving adequate exposure of mycophenolic acid (MPA) early post transplant is associated with less acute rejection in kidney recipients. Intensified dosing with the equivalent of mycophenolate mofetil (MMF) 3 g daily in tacrolimus-treated patients has been shown to increase exposure however about 15% remain below the lower therapeutic threshold of MPA area under the curve (AUC) of 30 mg · hr⁻¹ · L⁻¹ early post transplant. A post hoc analysis of this study showed that a target MPA AUC >40 mg · hr⁻¹ · L⁻¹ was most effective. The primary objective of this study was to determine whether 4 g daily of MMF would result in a greater proportion achieving adequate MPA exposure. MATERIALS AND METHODS: MMF 4 g daily was used in tacrolimus treated de novo kidney transplant recipients. A 3-point limited sample strategy was used to measure MPA AUC on days 5 and 14. Doses were adjusted at day 5 if exposure was high. RESULTS: In 30 patients, the mean AUC was 63 ± 28 mg · hr⁻¹ · L⁻¹ on day 5, with 13% (4/30) ≤ 30 mg · hr⁻¹ · L⁻¹ and 57% (17/30) >60 mg · hr⁻¹ · L⁻¹. The target MPA AUC was <40 mg · hr⁻¹ · L⁻¹ in 23% (7/30). Three patients developed gastrointestinal toxicity and required dose changes. Acute rejection occurred in only 2 patients (grade 1A and 2B) within 3 months (day 5 MPA AUCs were 29.9 and 33 mg · hr⁻¹ · L⁻¹. On day 14 the mean AUC was 46 ± 17 mg · hr⁻¹ · L⁻¹. Many were on MMF doses >2 g daily (8 on 3 g and 9 on 4 g daily). CONCLUSION: Compared to MMF 3 g daily, 4 g daily dose not result in a greater proportion adequately exposed. Rejections were few and occurred in the lower MPA exposed recipients. More than 50% of patients needed doses of MMF >2 g daily for 2 weeks to avoid underexposure. If intensified MPA dosing is considered, exceeding 3 g daily in tacrolimus-treated patients provides no added benefit.

RESUMO

BACKGROUND: Active surveillance (AS) represents a treatment option for renal masses in patients who are not surgical candidates either because of existing comorbidities or patient choice. Among renal masses undergoing AS, some grow rapidly and require treatment or progress to metastatic disease. Patient and tumour characteristics related to this more aggressive behaviour have been poorly studied. OBJECTIVE: To report the analysis of a multi-institutional cohort of patients undergoing AS for small renal masses. DESIGN, SETTING, AND PARTICIPANTS: This prospective study included 82 patients with 84 renal masses who underwent AS in three Canadian institutions between July 2001 and June 2009. INTERVENTION: All patients underwent AS for renal masses presumed to be renal cell carcinoma (RCC) as based on diagnostic imaging. MEASUREMENTS: Age, sex, symptoms at presentation, maximum diameter at diagnosis (cm), tumour location (central/peripheral), degree of endophytic component (1-100%), and tumour consistency (solid/cystic) were used to develop a predictive model of the tumour growth rate using binary recursive partitioning analysis with a repeated measures outcome. RESULTS AND LIMITATIONS: With a median follow-up of 36 mo (range: 6-96), the mean annual renal mass growth rate for the entire cohort was 0.25 cm/yr (standard deviation [SD]: 0.49 cm/yr). Only one patient (1.2%) developed metastatic RCC. Amongst all variables, maximum diameter at diagnosis was the only predictor of tumour growth rate, and two distinct growth rates were identified. Masses that are ≥2.45 cm in largest diameter at diagnosis grow faster than smaller masses. This series was limited by its moderate sample size, although it is the largest published prospective series to date. CONCLUSIONS: We confirm that most renal masses grow slowly and carry a low metastatic potential. Tumour size is a predictor of tumour growth rate, with renal masses <2.45 cm growing more slowly than masses >2.45 cm.

RESUMO

Three male physicians underwent transrectal ultrasound guided prostate biopsies for elevated prostate-specific antigen levels or irregular digital rectal exam findings. All three of these patients developed urosepsis secondary to multi-drug resistant organisms despite antibiotic prophylaxis. There are increasing reports of infectious complications following prostate biopsy caused by multi-drug resistant organisms. These cases highlight the potentially lethal risks to healthcare workers who are more likely to harbor multi-drug resistant organisms than the general population. Further research into preoperative assessment and appropriate antibiotic prophylaxis in all potentially high risk patients is warranted.

RESUMO

BACKGROUND: Several single nucleotide polymorphisms (SNPs) in the multidrug resistance (MDR1) gene may play a role in the interindividual variation of cyclosporine A (CsA) absorption in renal transplant patients. METHODS: An analysis of CsA absorption measured by the dose- and weight-adjusted 4 hr area under the time-concentration curve, AUC(0-4)/mg doseCsA/kg, was conducted on day 3 after transplantation, in 69 de novo renal transplant patients who were genotyped for MDR1 SNPs. Follow-up pharmacogenomic analysis at 1 month posttransplant was performed utilizing dose- and weight-adjusted 2-hour postdose CsA concentration (C2). RESULTS: AUC(0-4)/mg doseCsA/kg was significantly higher (P=0.024) in (C/C)3435 individuals than in a grouped population of (C/T)3435 and (T/T)3435 patients on postoperative day 3. G2677T variants were not significantly correlated with CsA absorption (P=0.084). The number of C3435-G2677 haplotypes was the best predictor of CsA exposure. At 1 month posttransplant, no correlation was seen between MDR1 SNPs and CsA exposure. The frequency of wild-type variants for C3435T and G2677T were 61% and 77.6%, respectively. SNPs at G2677T and C3435T loci were found to be in linkage disequilibrium. CONCLUSIONS: MDR1 polymorphisms are associated with differences in CsA exposure only in the first posttransplant week.

RESUMO

PURPOSE: In adults renal cell carcinoma (RCC) accounts for over 85% of all diagnosed renal cancers. A much more rare and aggressive malignant tumor of the kidney is angiosarcoma (AS) with less than 25 cases described internationally. Both RCC and AS have similar radiological appearances and thus require histological evaluation for definitive diagnosis. We present a case of renal AS in a 63-year old male who was initially radiologically diagnosed as RCC, and review the current renal AS literature. METHODS: The current English literature from 1981 and onwards on renal AS was reviewed and compared to our current case. RESULTS: The median age and sex of patients with renal AS at presentation was 63 years old (mean 61 years) and common in males with a left kidney predominance. Symptoms included flank pain, palpable mass, and hematuria with imaging suggestive of RCC. Hematogenous metastatic spread often occurred with median survival time of 3.5 months from time of diagnosis (mean 5.8 months). Histologically, the tumors have classical features of angiosarcoma with numerous blood-filled vascular spaces lined by plump pleomorphic endothelial cells with CD31 and CD34 staining positivity. Overall treatment was radical nephrectomy with radiation therapy for local control and metastases. The use of chemotherapy was not consistent. CONCLUSION: Although RCC accounts for the majority of malignant renal tumors, the poor prognosis of AS and its similar radiological appearance to RCC imparts the importance of histological evaluation and the potential radiological mimicry of AS.

RESUMO

INTRODUCTION: The purpose of this study was to determine the prevalence of erectile dysfunction (ED) at our institution in the postrenal transplant population and to compare those patients who had ED with those who did not have ED, with respect to several patient characteristics. METHODS: We conducted a cross-sectional study of male renal transplant recipients who were in attendance at the transplant clinic from April 1, 2004, to March 31, 2006. Erectile function was evaluated using the International Index of Erectile Function short form questionnaire. Patients were also screened for depression using the Beck Depression Inventory. We performed a chart review to obtain various patient characteristics. RESULTS: This study involved 55 patients. Their average age was 50 years old and the mean duration of the current transplant was 7.9 years. ED was identified in 28 of the patients (51%). More patients with ED were over age 50 years (64% v. 26%, p = 0.004). There was a higher prevalence of diabetes mellitus (39% v. 11%, p = 0.02) in patients with ED compared with those patients without ED. More patients with ED were depressed compared with those patients who did not have ED (29% v. 7%, p = 0.04). These 3 factors were significantly associated with ED and this relationship was confirmed on multivariate analysis. CONCLUSION: ED remains a common problem in the renal transplant population. The cause of ED is multifactorial, with increasing age and the presence of diabetes mellitus and depression increasing the risk of ED.

RESUMO

We report an unusual case of recurrent primary focal segmental glomerulosclerosis in an apparent low-risk cadaveric renal allograft recipient only 2 days after transplantation, who did not respond to repeated courses of plasmapheresis.

RESUMO

BACKGROUND: It has become increasingly important to refine therapeutic strategies according to individual patient characteristics. We evaluated the long-term impact of renal function at the time of withdrawing cyclosporine (CsA) in renal allograft recipients receiving sirolimus (SRL), CsA, and steroids (ST). METHODS: At 3 months+/-2 weeks, 430 of 525 patients were eligible to be randomized to remain on triple-therapy (SRL-CsA-ST, n=215) or to have CsA withdrawn (SRL-ST, n=215). Patients were divided into quartiles according to their baseline (last value before randomization) calculated GFR: 45 to 56 ml/min (quartile 2, n=105), >56 to 67 ml/min (quartile 3, n=112), and >67 ml/min (quartile 4, n=107). All data were included (ITT analysis). RESULTS: At 4 years, calculated GFR for SRL-CsA-ST vs. SRL-ST was 22.1 vs. 37.7 ml/min (P=0.017), 38.6 vs. 56.6 ml/min (P<0.001), 50.7 vs. 66.8 ml/min (P=0.006), and 62.7 vs. 71.4 ml/min (P=0.436), for quartiles 1 to 4, respectively. Death-censored graft loss ranged from 21.2% vs. 7.7% (SRL-CsA-ST vs. SRL-ST, P=0.092) in quartile 1 to 5.5% vs. 1.9% (P=0.618) in quartile 4. The incidence of death and biopsy-confirmed acute rejection also decreased with increasing baseline GFR, but was not significantly different between treatments. Overall, more patients remained on therapy in the SRL-ST group (46.3% vs. 57.9%, P=0.020). CONCLUSIONS: Early and complete withdrawal of CsA from a combination of SRL, CsA, and steroids was preferable to continuing on this regimen, regardless of baseline renal function. The benefit was most marked in patients with a baseline calculated GFR

RESUMO

We report the 48-month results of a trial testing whether withdrawal of cyclosporine (CsA) from a sirolimus (SRL)-CsA-steroid (ST) regimen would impact renal allograft survival. Eligible patients receiving SRL-CsA-ST from transplantation were randomly assigned at 3 months to remain on triple therapy (SRL-CsA-ST, n = 215) or to have CsA withdrawn and SRL trough concentrations increased (SRL-ST, n = 215). SRL-ST therapy resulted in significantly better graft survival, either when including death with a functioning graft as an event (84.2% vs. 91.5%, P = 0.024) or when censoring it (90.6% vs. 96.1%, P = 0.026). Calculated glomerular filtration rate (43.8 vs. 58.3 ml/min, P < 0.001) and mean arterial blood pressure (101.3 vs. 97.1 mmHg, P = 0.047) were also improved with SRL-ST. Differences in the incidences of biopsy-proven acute rejection after randomization (6.5% vs. 10.2%, SRL-CsA-ST versus SRL-ST, respectively) and mortality (7.9% vs. 4.7%) were not significant. SRL-CsA-ST-treated patients had significantly higher incidences of adverse events generally associated with CsA, whereas those in the SRL-ST group experienced greater frequencies of events commonly related to higher trough levels of SRL. In conclusion, early withdrawal of CsA from a SRL-CsA-ST regimen rapidly improves renal function and ultimately results in better graft survival.

RESUMO

The use of older cadaveric donors in kidney transplantation is increasing. The transplant outcome of the single older kidney is generally inferior prompting some to recommend dual kidney transplantation. The ability to predict the outcome of the solitary marginal kidney becomes clinically important. Such insight might allow for better allocation strategies that would minimize poorer outcomes while permitting optimal rationalization of this scarce resource. A retrospective, single center review of 79 single kidney transplants from 50 donors aged > or =55 yr was performed. We tested the validity of published scoring strategies to predict subsequent recipient kidney function. Receiver operating characteristic curve analysis was used to quantify the donor strategies separating good and poor outcomes based upon recipient creatinine clearance (CrCl) <30 mL/min. Two pre-transplant donor assessment strategies, Nyberg score and donor CrCl (dCrCl) were found to predict subsequent kidney function in recipients. When Nyberg variables (cold ischemia time, donor diabetes and hypertension status, incremental donor age >55 yr and cause of death) in conjunction with the dCrCl were considered, they were no better than dCrCl alone. Although dCrCl had a reasonable negative predictive ability, the positive predictive value was <50%. Our analysis suggests that a dCrCl of > or =70 mL/min is a better discriminator of subsequent kidney function outcomes than a dCrCl of 90 mL/min as recommended by the Dual Transplant Registry.
