The effectiveness of autologous demineralized tooth graft for the bone ridge preservation: a systematic review of the literature.

Resorption of alveolar ridge after tooth extraction often compromises dental implant placement and esthetic. Alveolar ridge preservation is a common procedure performed in order to preserve the pontic site for a prosthetically ideal position. This procedure has already become an indisputable need. Tooth matrix as bone substituted material poses osteoconduction and osteoinduction properties and as autologous graft, this material is free of antigenic reaction. This biomaterial allows the threedimensional reconstruction of the bone, is easy to prepare and has a low cost. The aim of this review is to summarize and put in evidence the properties of tooth as bone substitute and its use in alveolar ridge preservation. Keyword: autologous tooth, autologous graft, bone regeneration, bone substitute, alveolar ridge preservation, alveolar ridge augmentation, socket preservation.

Autologous tooth graft: a histological comparison between dentin mixed with xenograft and dentin alone grafts in socket preservation.

The aim of this study is to compare the histological results after socket preservation between dentin mixed with xenograft and dentin alone in tooth graft procedure. Six patients were included in this prospective case series study and treated in three clinical centers using standardized clinical procedures. This clinical trial enrolled patients with three walls post-extractive defects requiring the restoration of bone dimension and shape in mandibular zone. The patients were divided in two groups: extracted teeth alone (first group) and extracted teeth mixed with equal quantity of xenograft (second group). The extracted tooth was cleaned and processed by a recently introduced automated device, that allows fragmentation and partial demineralization of the tooth matrix and used as graft material. The graft obtained in this way, was inserted at the time of the extraction. A covering membrane was used to protect the graft. Implants were placed after 4 months of healing. Bone biopsies of the all grafted sites were taken at the time of implant surgery, for histological analysis. Descriptive statistics was used to synthesize the results, using mean values and standard deviations. Six patients (5 women, mean age at surgery 50.3±12.1 years) were treated and after 4 months of healing both groups, grafts height appeared stable. No signs of infection were present. Bone biopsy were taken in all grafted sites (3 with group one and 3 with group two). The histologic analysis revealed no inflammatory or infective reaction against both groups. The histomorphometry results between the two groups are different. The first group show an amount of new bone greater than the second group (+85.29%) and minor quantity of residual graft (-83.59%). The dentin alone shows a larger amount of new bone.

Rituximab in relapsing and de novo MPO ANCA-associated vasculitis with severe renal involvement: a case series.

BACKGROUND: Antineutrophil cytoplasmic antibody associated vasculitis (AAV) is a group of diseases associated in most cases with the presence of anti-neutrophil cytoplasmic antibodies (ANCAs). Rituximab- based remission induction has been proven effective in ANCA associated vasculitis but scarce data exist in forms with severe renal involvement. In this case series, we report the outcomes in patients with de novo or recurrent MPO-AAV and severe renal involvement treated with rituximab without cyclophosphamide (CYC). METHODS: In this single centre retrospective study, we analysed patients with a clinical diagnosis of de novo or recurrent AAV who met the following criteria: detection of P-ANCA, creatinine clearance lower than 30 ml/min, induction of remission therapy with rituximab without concomitant CYC and a follow up period of at least 6 months. The primary outcomes were complete remission after induction therapy, renal function recovery and mortality after the induction treatment. RESULTS: Eight patients met the inclusion criteria. The M:F ratio was 1:7, the average age was 54 years old and the median follow up was 10 months (7-72); in 2 patients there was a MPA renal limited vasculitis. A renal biopsy was performed in 7 patients. The median BVAS score at rituximab induction was 14(range 6-21). Two patients required haemodialysis before the induction treatment. Four patients developed end stage renal disease (ESRD) that required haemodialysis. These data show a remission of the disease, associated with a stabilization of the kidney function in 50% of patients. In 3 patients who did not show a response, there was also no response to CYC. CONCLUSIONS: This study shows a partial efficacy of rituximab in renal function recovery and a low risk of infectious complications in patients with MPO vasculitis with severe renal involvement, in particular in the short term. The optimal treatment in this subgroup of patients still has to be established because data are lacking.

Incidence of primary and second cancers in renal transplant recipients: a multicenter cohort study.

Limited data exist about cancer prognosis and the development of second cancers in renal transplant recipients. In a retrospective cohort study on 3537 patients incidence rates of the first and, if any, of a second cancer, and standardized incidence ratios [SIR (95% CI)] were computed. Two hundred and sixty-three (7.5%) patients developed a NMSC, and 253 (7.2%) another type of cancer after a median follow-up of 6.5 and 9.0 years, respectively. A statistically significant excess risk, if compared to an age- and sex-matched reference general population, was observed for Kaposi sarcoma and NMSC, followed by non-Hodgkin lymphoma and carcinoma of cervix uteri; a small number of unusual cancers such as tumors of the salivary glands, small intestine and thyroid also were detected at a level worthy of additional scrutiny. Ten-year survival rate of all noncutaneous cancers was 71.3%, with lower rates for lung carcinoma and non-Hodgkin lymphoma (0% and 41.7%, respectively). Patients with NMSC had an increased risk of developing a second NMSC [SIR 8.3 (7.0-10.0)], and patients with a primary noncutaneous cancer had increased risk of developing a second noncutaneous cancer [SIR 1.8 (1.2-2.8)], if compared to the whole cohort. Our study underscore that the high risk of primary and second cancer in renal transplant recipients, including unusual cancers.

Autologous tooth for bone regeneration: dimensional examination of Tooth Transformer® granules.

OBJECTIVE: Since 1967, when the osteoinduction properties of autogenous demineralized dentin matrix were discovered, autologous tooth grafts have been advocated as a viable option to autologous or heterologous bone graft. Tooth graft materials may be extracted from the patient's whole tooth using a granulating device. The aim of this study was to examine the size of granules obtained by the Tooth Transformer (TT)® device, using a laser instrument with high precision. MATERIALS AND METHODS: The TT® device can obtain bone graft material in a short period from an extracted tooth. The resulting material can act as an osteoconductive scaffold, providing a mineral substrate during resorption, including platelet growth factors and morphogenetic proteins. Different studies have investigated the dimension and behavior of various graft material particles, since the size of the grafted particles may play a role in osteogenesis and bone regeneration. RESULTS: Different dimensions of granules are available: small (< 400 µm), medium (400 µm-1,000 µm) and large (1,000 µm-2,000 µm). From 4.03 µm to 100 µm the percentage of granules was 14.52 ± 1.93%. A larger part of the granules was up to 100 µm, while 85.47 ± 1.93% of the granules were from 100 µm to 1,000 µm. CONCLUSIONS: 85% of the granules produced were in accordance with the dimensions suggested in the literature.

Dental erosion and the role of saliva: a systematic review.

OBJECTIVE: This review evaluates the relationship between saliva and dental erosion. The acidic environment that can be established in the mouth leads to dental erosion. Acid pH, low salivary flow, systemic pathologies of patients, intake of acidic foods, and poor oral hygiene contribute to an oral environment that favors the development of dental erosion. MATERIALS AND METHODS: A literature search was performed on PubMed, Scopus, and Web of Science databases to assess the role of saliva and dental erosion. The inclusion criteria for the search were: year of publication from January 1st, 2013, to March 1st, 2023, and English language. RESULTS: A total of 3,597 articles covering our topic were found, of which 15 were selected for qualitative analysis. CONCLUSIONS: Saliva protects against erosion by neutralizing and removing intrinsic and extrinsic acids, promoting the formation of an acquired protective film, and providing mineral substrates for remineralization by maintaining homeostasis in the digestive tract and oral cavity.

Caries prevention and treatment in early childhood: comparing strategies. A systematic review.

OBJECTIVE: Early childhood caries is a common condition that poses a serious risk to children's health because it can progress quickly, resulting in pain, abscesses, and a general decline in health. As a result, invasive therapies are needed, which call for highly skilled personnel. This systematic review of the literature aims to identify the most recent and widely applied early childhood caries (ECC) prevention and treatment approaches. Only substances that act topically and minimally invasive interventions were considered. MATERIALS AND METHODS: The database search was restricted to randomized clinical trials completed within the last five years, specifically those that examined the following procedures: sodium fluoride (NaF) varnish, alternative restorative technique (ART), nano-silver fluoride, silver diamine fluoride, and silver modified atraumatic restorative treatment sealants (SMART). RESULTS: A total of 815 articles were found. After removing duplicates, 584 articles were included, and 567 of them were excluded due to not meeting the predefined inclusion criteria. CONCLUSIONS: Every method considered has been proven to be successful in halting the progression of ECC and is well-liked by patients, even those who are unwilling to cooperate, as well as by parents. The most common unfavorable effect of SDF is irreversible black discoloration in treated tooth surfaces, but this is typically not a problem. They are all low-cost, minimally invasive techniques that might also be widely used in large communities and low socioeconomic settings.

Direct and indirect bonding techniques in orthodontics: a systematic review.

OBJECTIVE: Some of the most significant aspects in orthodontics for achieving favorable treatment outcomes include correct bracket positioning and a shorter period to accomplish bracket bonding. Two different brackets bonding techniques - direct and indirect bonding - are described in the literature. The aim of this review is to evaluate the differences, advantages, and disadvantages of the two techniques. MATERIALS AND METHODS: A literature search was conducted on PubMed, Scopus, and Web of Science databases in a period from January 2013 to April 2023 with English language restriction using the following Boolean keywords: "orthodontic bracket* AND (bonding OR placement)". RESULTS: A total of 3,820 articles were identified by the electronic search, and after duplicate removal, screening, and eligibility, a total of 11 papers were included for the qualitative analysis. CONCLUSIONS: Indirect bonding is more predictable and precise than direct bonding. Indirect bonding has a greater impact on minimizing bracket placement errors than direct bonding, but it still takes longer to complete than the traditional procedure. However, further studies on the differences between direct and indirect bonding, as well as digital bonding, are needed.

Impact of 3 Major Maintenance Immunosuppressive Protocols on Long-term Clinical Outcomes: Result of a Large Multicenter Italian Cohort Study Including 5635 Renal Transplant Recipients.

BACKGROUND: Although optimization of immunosuppressive schemes in renal transplantation have minimized acute posttransplant complications, long-term outcomes are still not optimal and most of the chronic graft damage is drug-related. Therefore, to define the best long-term maintenance immunosuppressive regimen is of major importance in renal transplantation. To assess this objective, we undertook a large, multicenter cohort study in Italy. METHODS: We retrospectively analyzed data of 5635 patients (enrolled from 1983 to 2012) and we assessed the impact of 3 major immunosuppressive regimens (calcineurin inhibitors+antimetabolites+corticosteroids [CNI+ANT+CS] vs CNI+mammalian target-of-rapamycin (mTOR) inhibitors+CS [CNI+mTOR-I+CS] vs CNI+CS) on long-term clinical outcomes by employing several statistical algorithms. RESULTS: The overall difference in the incidence of outcome over time was not statistically different within the first 5 years of follow-up (P = .13); however, it became significant at 10 years and 20 years (P < .01), with the CNI+CS group showing the lowest cumulative incidence of outcome. Compared with the CNI+ANT+CS group, the CNI+mTOR-I+CS group patients had a significantly higher risk of outcome (hazard ratio [HR], 1.30; P = .024); the difference remained significant and even increased in magnitude after adjustment for potential confounders (HR, 1.38; P = .006). Similarly, patients in the CNI+CS group had a significantly higher risk of the outcome (HR, 1.64; P < .001). CONCLUSION: Our data confirm that CNI+ANT+CS is the "gold standard" therapy in renal transplantation, but, whenever required, the introduction of mTOR-Is instead of ANT may not dramatically modify major clinical outcomes. The use of mTOR-I could be a valuable pharmacologic tool to minimize CNI complications and insure adequate immunosuppression.

Anemia and Immunosuppressive Regimen in Renal Transplanted Patients: Single-Center Retrospective Study.

We compared retrospectively the level of hemoglobin and the percentage of patients with anemia among 59 kidney transplant recipients receiving everolimus, cyclosporine, and corticosteroids and 128 treated with cyclosporine, mycophenolic acid, and corticosteroids. We also compared age at the time of transplantation, sex and ferritine, serum creatinine, creatinine clearance, folic acid, cyanocobalamine levels, use od recombinant erythropoietin, mean corpuscolar volume at the last ambulatory control. Statistical analysis included Student t test, χ(2) test, and logistic regression. The analysis was performed using SPSS software. We observed no difference in terms of hemoglobin levels in patients treated with everolimus (12.9 ± 1.6 vs 12.7 ± 1.5 g/dL). Anemia (defined as hemoglobin <13 g/dL in men and <12 g/dL in women, or need to use erythropoietin) was found in 49% and 45% of patients in the 2 groups respectively (P = .6). The other parameters evaluated were similar except for the mean corpuscular volume, which was significantly lower in the everolimus group. In the multivariate analysis only serum creatinine and estimated glomerular filtration rate influenced the level of hemoglobin. We observed no differences in terms of development of anemia in renal transplanted patients treated with everolimus-based regimen.

Laparosopic hand-assisted living donor nephrectomy: the Niguarda experience.

Perioperative donor morbidity, a barrier to living organ donation, may be mitigated by the laparoscopic approach. From September 2002 to September 2004, 15 living donors, of ages ranging from 36 to 59 years, underwent laparoscopic nephrectomy. We used a hand-assisted device to increase the safety of the procedure. The average operating time was 200 minutes. The average blood loss was about 100 mL. The patients resumed oral intake and started walking within 1 day. The average postoperative hospital stay was 6 days. Although laparoscopic operating times were longer than those for traditional surgery, we showed benefits to the laparoscopic donor to be less postoperative pain, better cosmesis, shorter recovery time, and faster return to normal activities. We therefore consider laparoscopic nephrectomy a good alternative to traditional surgery for selected patients. Despite a lack of strong evidence, such as large prospective randomized studies, laparoscopic donor nephrectomy is likely to become the gold standard for donor nephrectomy in the near future.

Advantages of short-time ureteric stenting for prevention of urological complications in kidney transplantation: an 18-year experience.

We retrospectively studied the incidence of urological complications in a consecutive series of 590 patients (group B) who received a kidney transplant (KT) with a ureteral stent from January 1994 to December 2002. The ureteral stent was sewn to the bladder catheter during the surgical procedure and left in situ for a mean time of 10 days (range 8 to 12 days). The results were compared to a consecutive series of 414 patients who received a KT from March 1986 to December 1993 without a ureteral stent (group A). The two groups were comparable in terms of donor and recipient gender, ischemia time, delayed graft function, and chronic rejection incidence, but differed in mean donor age (44.1 vs 36.0 years), mean recipient age (45.4 vs 39.1 years), living/cadaveric donor rate (19.8% vs 11.9%), arterial lesions and bench reconstruction rate (11.1 vs 3.5%), as well as acute rejection episodes (11.7% vs 29.2%). Complications were seen in nine patients in group B (1.5%) and 17 patients in group A (4.1%) (P < .0001). Urinary leaks presented in two patients in group B (0.3%) and 11 patients in Group A (2.6%; P < .0001), while stenosis was present in six patients in group B (1.5%) and 7 in group A (1.2%) (P = NS). Urological complications such as urinary tract infection and macroscopic hematuria were similar in both groups. Time to presentation of a leak was within 2 weeks from KT in 10 patients (92.3%), while stenosis presented early in four patients (one in group B and four in group A). Of the stenoses, 69.3% presented late (beyond 12 weeks) in five patients in group B and three in Group A. In conclusion, our data suggest that routine use of double pigtail ureteral stent significantly decreased the incidence of leaks and early stenoses, but it did not modify late stenosis incidence. In the last decade, risk factors for urological complications have been increasing over time, namely, older donors and older recipients, living donation, length of dialysis, and the use of grafts with arterial lesions. Therefore we believe that a ureteral stent should be routinely considered to afford the advantage to protect the urinary anastomosis in the early postoperative period when the incidence of complications is highest, without the need of cystoscopy for its removal.

Surgical complications are the main cause of pancreatic allograft loss in pancreas-kidney transplant recipients.

We examined surgical complications among a group of diabetic type 1 patients (IDDM) with end-stage renal disease (ESRD) who had undergone pancreas-kidney transplantations (PK). Between October 1993 and August 2004, 70 SPK were performed using bladder (n = 14) or enteric (n = 56) drainage. Donors were selected according to standard criteria (mean age, 27.6 years; range, 17-49). All patients received cyclosporine-based immunosuppression. All pancreata functioned immediately, whereas 2 patients needed postoperative dialysis. Four patients (5.7%) lost their pancreatic graft due to vascular thrombosis; both patients underwent urgent allograft pancreaectomy and pancreas retransplantation (re-PT). One of them (1.4%) experienced a venous thrombosis and died due to a pulmonary embolism at 12 hours after re-PT. The other 3 patients had uneventful postoperative courses and were discharged with good pancreatic and renal function. Three patients in the bladder group (21.4%) had an anastomotic leak, which resolved with a bladder catheter. Four patients in the enteric group (7.1%) who experienced an anastomotic leak needed a second surgical procedure but in 3 of them allograft pancreatectomy was necessary. Relaparotomy was required in the other 3 patients due to hemorrhage (1 patient) or occlusion (2 patients). Acute rejection episodes, which occurred in 16 patients (22.8%), were treated with steroid boluses. With a mean follow-up of 72 months (range, 3-129), 2 patients have died at 8 and at 36 months, respectively, after SPK due to acute myocardial infarction (2.9%). Chronic rejection was the leading cause of pancreatic failure in 5 patients (7.1%) and of renal failure in 2 patients (2.8%). Patient, kidney, and pancreas survival rates were 95.8%, 92.9%, and 81.5%, respectively. Surgical complications were the leading cause of pancreatic allograft loss in IDDM and ESRD patients submitted to SPK.

[Renal transplantation in the North Italy Transplant program (NITp): Organ allocation and results]. / Il trapianto renale nel Nord Italia Transplant program (NITp): assegnazione degli organi e risultati.

Renal transplantation is an effective therapeutic tool for patients with end-stage renal diseases (ESRDs). Data reported in this article summarize the results obtained from 30 years' activity in the North Italy Transplant program (NITp), the first transplant organization in Italy that implemented a donor procurement and organ transplantation network. In the NITp kidney allocation is governed by a computerized algorithm, NITK3, put in place in 1997, aimed at ensuring equity, transparency and traceability during the stages of the allocation decision-making process. The NITp working group has recognized the NITK3 criteria and they are periodically reviewed following the results of the analysis of patients' transplantation odds. The results obtained with the use of the NITK3 algorithm have been very satisfactory: after 6 yrs, a significantly higher percentage of patients at immunological risk (sensitized or waiting for re-transplant), of patients waiting for >3 yrs and of patients with 0-1 HLA A,B,DR mismatches have been transplanted. Moreover, a higher percentage of kidneys were used locally (in a hospital within the procurement area), and this is known to stimulate donor procurement. Finally, we performed a preliminary statistical analysis of transplants carried out from 1998-2002 in 5/16 centers of the NITp area, demonstrating the quality of the NITp program in terms of patient and graft survival, and that donor and recipient age are the variables significantly impacting on transplant results.

Effect of familial hypertension on glomerular hemodynamics and tubulo-glomerular feedback after uninephrectomy.

Familial hypertension, glomerular hemodynamic alterations, and dysregulation of tubulo-glomerular feedback (TGFB) have all been associated with the development of chronic renal failure. In the present study we evaluated renal and glomerular hemodynamics and TGFB responses in healthy kidney donors either with or without familial hypertension, before and after nephrectomy. Para-amino-hippurate plasma clearance (CPAH) and inulin plasma clearance (CInu) were measured in 15 kidney donors before and 1 year after nephrectomy. All subjects were normotensive and were kept in a sodium-replete state. Both clearances were measured after 40 min of constant infusion of PAH and Inu, as well as 20, 30, 50, and 60 min after the intravenous administration of acetazolamide (5 mg/kg). Glomerular hemodynamics were calculated by means of the Gomez formulae. Nephrectomy caused the expected decreases in CPAH and CInu and increase in the filtration fraction (all P < .0001). The decrease in renal resistances of the remaining kidney was greater at the afferent (-24%, P = .0075) than at the efferent arteriolar level (-17%, P < .0001). The TGFB activation was not altered by nephrectomy or by familial hypertension. Effective renal plasma flow (ERPF) decrease after TGFB activation appeared earlier than glomerular filtration rate (GFR) decrease before (P = .01), but not after, nephrectomy (P = .48). The presence of familial hypertension was associated with increased glomerular pressure (P = .0004). This study suggests that uninephrectomy in healthy human subjects causes a greater decrease in afferent arteriolar resistances, but that TGFB responses are not quantitatively altered. Familial hypertension is associated with a tendency toward higher glomerular pressures.

Urinary salt titrator stick: a useful and quick estimate of dietary sodium intake?

Repeated measures of urinary salt excretion are the best compromise between reliability and convenience for estimating dietary salt intake. In order to assess the accuracy of the Uropaper urinary salt titrator stick (giving discrete readings of 4, 6, 8, 10, 12 or 14 g/l of NaCl), 312 urine samples were analysed both with the stick and with an ion-selective electrode. There was a good stick-electrode correlation in all the 312 samples (r = 0.84). With a tolerance of +/- 1 g/l, the percentages of correct estimations dropped from 82% to 33% with increasing concentrations of NaCl in the urinary sample. For NaCl concentrations greater than 8 g/l (137 mmol/l) the error in the stick measurement consisted almost exclusively of overestimation of the electrode readings. These results were unaffected by the concentration of urinary potassium. No discrepancies were found among three different readers. This stick is easy to use and measures, with reasonable accuracy, low urinary NaCl concentrations. It could be useful for self-monitoring during low NaCl diets.

Is lymphocele in renal transplantation an avoidable complication?

BACKGROUND: This study evaluated the impact of surgery in the incidence of lymphocele after kidney transplantation (KTx). METHODS: A prospective randomized study was conducted during a 6-year period on a group of patients undergoing KTx and operated on by the same surgeon (CVS). A total of 280 patients undergoing KTx were randomly allocated into two groups: (1) group C (control group) was 140 patients who were submitted to KTx with standard technique: implantation of the kidney in the controlateral iliac fossa with vascular anastomoses on the external iliac vessels; and (2) group M (modified technique group) was 140 patients who underwent a modified technique with a cephalad implantation of the graft in the ipsilateral iliac fossa and vascular anastomoses in the common iliac vessels. Both groups were comparable for age, cold ischemia time, incidence of rejection episodes, presence of adult polycystic kidney disease, and source of donor graft. RESULTS: Group M showed an incidence of lymphocele production (3 patients, 2.1%) significantly lower than group C (12 patients, 8.5%). Eight patients (1 in group M and 7 in group C) required surgical treatment by peritoneal fenestration. No allograft or recipient was lost as a result of fluid collection but the hospitalization was shorter in group M than in group C. CONCLUSIONS: A cephalad implantation of the renal graft in the ipsilateral iliac fossa has been associated with a lower incidence of lymphocele, probably because vascular anastomoses on the common iliac vessels cause less lymphatic derangement than those performed on the external iliac vessels.

Effect of n-3 polyunsaturated fatty acids on cyclosporine pharmacokinetics in kidney graft recipients: a randomized placebo-controlled study.

Highly concentrated marine polyunsaturated fatty acids (n-3 PUFA), affecting the lipids and lipophilic drugs metabolism, can interfere with cyclosporine (CyA) pharmacokinetics. This prospective, randomized and placebo-controlled, double-blind study involved 42 kidney graft recipients. From day +1, 21 pts (E) received 6 g n-3 PUFA (85% EPA + DHA, Esapent, Pharmacia) and 21 pts (P) received placebo (olive oil), both reduced to 3 g from day +30 on. A quadruple immunosuppressive regimen was employed. Plasma creatinine, lipids and CyA pharmacokinetics were investigated 1, 3, 6, 9 and 12 months after graft. The two groups were comparable for age, weight, M/F ratio, hypertension prevalence and baseline lipids. Active treatment did not affect total and HDL-cholesterol, but significantly lowered triglycerides (E:120 +/- 12 vs P:166 +/- 21 mg/dl, p < 0.0001). At one year, E pts had lower creatinine than P (1.26 +/- 0.06 vs. 1.88 +/- 0.2 mg/dl, p < 0.05), comparable CyA dosage, and a larger CyA area under the curve (AUC) (n.s.), with a higher blood peak level (Cmax) (p < 0.04) and less variance in time to peak (n.s.). The larger AUC in the E group at all intervals and the better pattern of plasma creatinine, with no rise in blood pressure, provided evidence of better CyA absorption and metabolism in n-3 PUFA supplemented kidney graft recipients.

5 year comparison of very low-dose cyclosporine and high-dose everolimus vs standard cyclosporine and enteric-coated mycophenolate in renal transplantation patients.

In this retrospective study, we compared the outcome of renal transplanted patients who received everolimus (EVR) (C0: 8-12 ng/mL)+cyclosporine (CsA) (C2: 150-300 ng/mL)+steroids, vs those who received enteric-coated mycophenolate sodium (EC-MPS) (1,440 mg/d)+CsA (C2: 500-700 ng/mL)+steroids. Efficacy was evaluated at 5 years. We found a nonsignificant trend toward a better 5-year graft survival (81.2% vs 68.6%) and better graft function (estimated glomerular filtration rate 71.8±35.7 vs 60.0±26.2 mL/min, P=.114) in favor of the EVR group. In our experience, EVR with a very low dose of CsA was associated with a nonstatistical trend toward better renal function and graft survival compared to a standard regimen of CsA and EC-MPS.
