RESUMO

BACKGROUND AND AIMS: Cardiovascular disease (CVD) is one of the leading causes of mortality in obese patients. We aimed to investigate the influence of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on carotid intima media thickness (CIMT) and epicardial fat thickness (EFT) which are the independent predictors of subclinical atherosclerosis. METHODS AND RESULTS: Patients were recruited for standard indications. A total of 105 patients (79 women and 26 men) with the mean age of 43.61 ± 12.42 were prospectively enrolled. On B-mode duplex ultrasound; the mean CIMT at the far wall of both left and right common carotid arteries were measured. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Delta (Δ) values were obtained by subtracting sixth month values from the baseline values. Body mass index (BMI) was significantly reduced from 46.95 ± 7.54 to 33.54 ± 6.41 kg/m2 (p < 0.001) in sixth months after LSG. Both EFT and CIMT were significantly decreased after surgery (8.68 ± 1.95 mm vs. 7.41 ± 1.87 mm; p < 0.001 and 0.74 ± 0.13 mm vs. 0.67 ± 0.11 mm; p < 0.001 respectively). A significant correlation between ΔEFT and ΔBMI (r = 0.431, p < 0.001) was shown. ΔCIMT is significantly correlated with ΔEFT, ΔBMI and Δ systolic blood pressure (r = 0.310, r = 0.285 and r = 0.231 respectively, p < 0.05 for all). In multivariate stepwise linear regression analysis; among variables only ΔBMI was the independent predictor of ΔEFT (ß = 153, p = 0.001). CONCLUSION: Early atherosclerotic structural changes may be reversed or improved by sustained weight loss after LSG in asymptomatic obese patients.

RESUMO

BACKGROUND: The observation that long-standing hyperuricemia is associated with chronic tubulointerstitial disease, afferent arteriolopathy, intrarenal vasoconstriction, and increased vascular resistance raises the hypothesis that hyperuricemia might contribute to chronic cyclosporine (CsA) nephropathy. The aim of the present study was to investigate the effect of hyperuricemia on chronic CsA nephropathy. METHODS: Patients who were treated with CsA-based immunsuppressive regimens and underwent a renal biopsy were enrolled in this case-control study. We retrospectively obtained posttransplant baseline serum creatinine, uric acid (UA), mean serum UA, and creatinine values 3 months prior to biopsy. CsA trough levels, mean blood pressure, diuretic and antihypertensive treatment were recorded. Biopsy specimens showing CsA nephropathy (n = 34) were revaluated by a pathologist to score CsA nephropathy according to recent quantitative criteria for calcineurin inhibitor arteriolopathy as proposed by M.J. Mihatsch. RESULTS: As compared with the non-CsA nephropathy group, recipient and donor ages, donor origin and cold ischemia times were similar for the CsA nephropathy group (P > .05). Mean CsA doses, CsA trough (C(0)), and C(2) levels were not different between the groups (P > .05). Systolic and diastolic blood pressure, glomerular filtration rate, diuretic usage, and antihypertensive treatment were also similar in CsA nephropathy and non-CsA nephropathy groups (P > .05). Mean serum UA level within 3 months prior to biopsy in the CsA nephropathy and non-CsA nephropathy groups were 7.5 +/- 1.4 mg/dL versus 5.7 +/- 1.4 mg/dL, respectively (P < .001). CONCLUSION: Hyperuricemia seems to exacerbate CsA-induced nephropathy.

RESUMO

BACKGROUND: Vascular endothelial growth factor (VEGF) expression influences tubular repair and promotes angiogenesis. The aim of the present study was to determine the relation of VEGF expression and cortical vascularity with renal pathological changes and clinical parameters in allograft biopsies. MATERIALS AND METHODS: Sections from 50 renal allograft biopsies were evaluated by streptavidine-biotin immunohistochemistry by primary antibodies against VEGF and CD34. Cortical tubulointersititial (TI) VEGF expression was scored by light microscopic examination considering intensity and density. Glomerular expression was scored as 0: no staining; 1: faint staining in less than 50% of glomeruli; 2: moderate to strong staining in more than 50% of glomeruli. We determined the number of vessels per cortical high power field (Nves) highlighted by CD34 staining. The clinical and pathological features were retrieved from patient files. RESULTS: Nves was decreased with interstitial fibrosis (IF): 56.3 +/- 3.7; 53.3 +/- 9.8, 46.6 +/- 10.5, 36.75 +/- 1.89 for cases with no IF to mild, moderate, and severe forms, respectively (P << .000). There was increased TI VEGF expression: 1.86 +/- 2.12, 5.8 +/- 3.1, 5.85 +/- 4.4, 10.25 +/- 2.06, respectively (P = .004). The NVes values were not different for cases with high and low to negative VEGF expression scores. There was a negative correlation between Nves values and creatinine at the time of biopsy and time from transplantation to biopsy (r = -.325, P = .024 and r = -.294, P = .038, respectively). Nves and VEGF scores were not different when acute rejection scores or cyclosporine toxicity were considered (P > .05), while Nves were significantly different for chronic allograft nephropathy scores (P = .05). CONCLUSIONS: Chronic renal changes seemed to be associated with decreased cortical vascularity in renal allografts, while the TI VEGF expression was increased. In contrast Nves was not increased with VEGF expression in this series. It seems that along with VEGF, other factors are required for protection against vascular reduction. The aging of the allograft is also a negative influence on cortical vascularity.

RESUMO

Acute humoral rejection (AHR) is generally less responsive to conventional anti-rejection treatment with consequent allograft losses. Therapeutic options include antilymphocyte antibody (ATG), intravenous immunglobulin (IVIG), plasmapheresis, or immunoadsorption with protein A together with intensification of immunsuppression with a tacrolimus/mycophenolate mofetil combination. This report describes a transplant recipient who responded to rituximab therapy as treatment for steroid-, ATG-, IVIG-, and plasmapheresis-resistant AHR.

RESUMO

Patients with systemic amyloidosis often have symptoms related to impared gastrointestinal motility due to delayed gastric emptying, which results from autonomic nerve or smooth muscle infiltration with amyloid. There is no current report about gastric delaying secondary to amyloidosis due to familial Mediterranean fever. In this report, we have described a renal transplant recipient with delayed gastric emptying secondary to amyloidosis due to familial Mediterranean fever, which improved with erithromycin treatment.

RESUMO

INTRODUCTION: Primary hyperoxaluria type-1 (PH1) is an autosomal recessive disorder caused by impaired activity of the hepatic peroxisomal alanine-glyoxilate aminotransferase, which leads to end-stage renal disease (ESRD) and requires combined liver-kidney transplantation (CLKT). Herein, we have reported 3 children diagnosed with PH1 who received CLKT. CASE 1: A 4.5-year-old boy with an elder brother diagnosed with PH1 was diagnosed during family screening when the sonography showed multiple calculi. Within 5 years he experienced flank pain, hematuria attacks, and anuric phases due to obstruction and received hemodialysis (HD) when ESRD appeared. CLKT was performed from his full-match sister at the age of 9.5. He is doing well at 5.5 years. CASE 2: A 7-year-old boy was admitted with polyuria, polydypsia, and stomach pain with renal stones on sonography. PD was instituted when serum creatinine and BUN levels were measured as high values. At the age of 10, CKLT was performed from his mother. His liver and renal function tests are well at 14 months after CKLT. CASE 3: A 2.5-year-old girl had attacks of dark urine without any pain; renal stones were imaged on sonography. She was diagnosed with PH1 and operated on several times due to obstruction. She received peritoneal dialysis and a cadaveric CLKT was performed when she was 9 years old. At the age of 16, she experienced chronic allograft nephropathy requiring HD and subsequent cadaveric donor renal transplantation at 1.5 years after initiation of HD. CONCLUSION: Herein, we have presented the favorable clinical outcomes of patients with CKLT to indicate the validity of this treatment choice for PH1.

RESUMO

INTRODUCTION: Because of the shortage of organs available for transplantation, living related sequential transplantation with the use of liver and a kidney from the same donor has emerged as a reasonable therapeutic alternative. However, there is insufficient literature about the complications that living donors experience after simultaneous kidney and liver transplantations. METHODS: From December 2001 to October 2009, 5 living donors provided simultaneous donation of livers and kidneys and 1 living donor donated first her kidney and then her liver. Demographic data of the donors and information concerning the surgery and postoperative observation were collected prospectively. RESULTS: All of the donors were female. The median age was 27.5 (range, 19-36) years. Indications requiring the simultaneous transplantation of livers and kidneys were primary hyperoxaluria type 1 (PH1) in 5 potential recipients and cirrhosis due to chronic hepatitis B infection and idiopathic chronic renal insufficiency in 1 potential recipient. Four recipients underwent right hepatectomy (segments 5-8) and right nephrectomy; 1 recipient underwent left hepatectomy (segments 2-4) and right nephrectomy; and 1 recipient underwent left lobectomy (segments 2-3) and right nephrectomy. There were no complications except in 1 donor (postoperative ileus). No donor developed hypertension or microalbuminuria. CONCLUSIONS: With the right indications, appropriate preoperative evaluation, meticulous surgical technique, proper postoperative care, and long-term close monitoring to minimize morbidity and mortality risks, liver and kidney donation from the same donor can be considered for simultaneous kidney and liver transplantation.

RESUMO

OBJECTIVE: To test the hypothesis that the renal medulla may reflect rejection related changes and thus have a predictive value in the assessment of acute renal allograft rejection or chronic graft damage. METHODS: 75 post-transplant biopsies from 57 patients were scored according to the Banff 1997 scheme. The biopsies with adequate cortical and medullary tissue (n = 23) were selected and medullary tissues were reviewed for rejection related lesions except intimal arteritis. Chronic damage was determined by image analysis depending on periodic acid-methenamine silver (PAMS)-Masson trichrome (MT) staining. Medullary and cortical changes were compared. RESULTS: Interstitial inflammation and tubulitis were more frequent and severe in the cortex (p<0.001). Medullary tubulitis was associated with intimal arteritis (p = 0.003, r = 0.598). Medullary interstitial inflammation (n = 8) and tubulitis (n = 4) were associated with cortical borderline changes (n = 5) or allograft rejection (n = 3). The sensitivity, specificity, and positive and negative predictive values of medullary inflammatory changes in predicting cortical allograft rejection were 43%, 69%, 37%, and 73%, respectively. A significant association was observed between medullary MT-SAP and cortical PAMS-SAP values (p = 0.02, R(2) = 0.23). CONCLUSIONS: Acute rejection related lesions are more common and severe in the cortex, and the renal medulla does not sufficiently reflect cortical rejection. The positive and negative predictive values of medullary changes for allograft rejection are low, and medullary inflammation is not a reliable indicator of allograft rejection. Increased medullary fibrosis is correlated with chronic cortical damage.

RESUMO

INTRODUCTION: The impact of obesity, a frequent problem after renal transplantation, which has been associated with poor graft and patient survival, was evaluated on renal function and cyclosporine (CsA) blood levels. PATIENTS: We retrospectively evaluated the data of adolescent renal recipients between 1994 and 2004. Patients with serum creatinine > or = 2.5 mg/dL were excluded. We grouped the data with regard to the body mass index (BMI) percentiles as group I (BMI > 95th), group II (BMI < 95th), group III (BMI > 85th), group IV (BMI < 85th). We compared the clinical and laboratory findings between groups I and II and between groups III and IV. RESULTS: We evaluated 778 visits of 27 patients (M/F: 19/8). There were 30 visits in the obesity period (group I) and 72 visits after the overweight periods were added (group III). Serum creatinine levels were significantly higher and glomerular filtration rate levels significantly lower among obese and/or overweight than lean periods (P < .05). Proteinuria levels were similar in groups I and II, but significantly higher in group III than group IV (P = .356 and .000, respectively). CsA(mg/bw), CsA(mg/bmi), and CsA(mg/bsa) levels were significantly lower in group I than group II and in group III than group IV (P < .05), while C0 and C2 levels were similar (P > .05). CONCLUSION: Weight gain is associated with worse renal functions but not greater proteinuria in our patients. Smaller CsA doses were sufficient to maintain C0 and C2 levels similar to the lean patients, results that were parallel to those of adult renal recipients.

RESUMO

Hyperlipidemia is a frequent complication after renal transplantation. Cyclosporine therapy is an important cause of hyperlipidemia. It is still controversial whether C0 or C2 is the most effective way to monitor blood cyclosporine concentrations to guide dosages. We sought to evaluate the relationship of C0 or C2 to serum lipid levels in the early and late posttransplant periods among adolescent renal transplant recipients. The posttransplantation charts of 26 adolescent renal transplant recipients were evaluated retrospectively. Serum C0 and C2 levels and serum lipid (triglyceride and total cholesterol) levels were analyzed both in the early (first 6 months) and the late (thereafter) posttransplant periods. Hypertriglyceridemia and hypercholesterolemia were defined as levels above the 95th percentile adjusted for age and gender. To evaluate the influence of C0 and C2 levels on serum lipids, we excluded one patient with familial hyperlipidemia. In addition, serum lipid levels of the remaining 25 patients were excluded in acute rejection periods and when the serum creatinine levels were above 2.5 mg/dL, representing chronic allograft nephropathy. Concurrently recorded serum C0 and C2 levels were present for only 21 patients. Overall, we evaluated the records of 245 visits for these 21 patients. The incidence of hyperlipidemia decreased in the late posttransplant period, being significant for hypercholesterolemia. C2 had strong negative correlation with serum lipids; it was significant for total cholesterol in the early posttransplant period (r=-0.542, P=.005), but weaker in the late posttransplant and whole posttransplant periods. Thus correlation of C2 with serum lipids showed differences during posttransplant follow-up. C0, on the other hand, was positively correlated with total cholesterol levels in all periods, being significant for the whole posttransplant period (r=0.293, P=.000) and for the late posttransplant period (r=0.196, P=.025). Although not statistically significant, C0 levels were higher among hypertriglyceridemic or hypercholesterolemic episodes both in the early and the late posttransplant periods. When only the C0 levels of all 25 patients were analyzed (789 visits), C0 and serum cholesterol levels were positively correlated both in the early and the late posttransplant periods (P=.013, r=0.198 and P=.000, r=0.177, respectively). We concluded that C0 has a more predictable correlation with serum cholesterol levels after renal transplantation in adolescent patients.

RESUMO

The aim of this retrospective study was to investigate the results of kidney transplantation in patients with renal amyloidosis. We analyzed the results of renal transplantation in 13 amyloidotic transplant recipients compared with those in a control group of 13 nonamyloidotic patients. While the etiology of amyloidosis was rheumatoid arthritis in one patient, in all of the others it was secondary to familial Mediterranean fever. Acute rejection episodes developed once in six and twice in one patient. The renal function in these patients was improved by antirejection treatment. Chronic rejection did not develop in any patient. However six patients (46%) died due to various complications despite functional grafts. The others are still being followed with well-functioning grafts. Among the control group, acute and chronic rejection were diagnosed in three and two patients, respectively: one patient returned to hemodialysis after 26 months of transplantation, while the others are still alive with functional grafts. There was no death in the control group. The 5- and 10-year actuarial patient survival rates of the amyloidosis and control groups were 52.2%, 26.6%, and 100%, 100%, respectively (P = .002). However, the graft survivals of the amyloidosis versus control groups were 100%, 100%, versus 87.5%, 87.5, respectively (P = .47). In conclusion, we observed a high rate of early mortality among recipients with amyloidosis associated with infectious complications. Moreover, patient survivals were lower among amyloidotic renal recipients.

RESUMO

The mechanism of posttransplantation avascular osteonecrosis (AVN) is controversial. Besides an increased bone marrow pressure due to reduced blood supply, enhanced coagulation has been considered. We investigated the associations of factor V Leiden, prothrombin G20210A, and MTHFR C677T mutations as well as cumulative corticosteroid doses with AVN in renal allograft recipients. The records of 39 volunteer patients and 11 patients in whom osteonecrosis was previously identified were reviewed for cumulative corticosteroid dosages during the first year. All patients were screened for factor V Leiden, prothrombin G20210A, and MTHFR C677T mutations by direct sequencing of genomic DNA. The cumulative corticosteroid dosages at 3, 6, and 12 months in the osteonecrotic group (5033.5 +/- 1565.3, 7164.9 +/- 2063.1, 8835.1 +/- 2216.8 mg) were significantly higher than in the control group (3629 +/- 1504.1, 4784.5 +/- 1568.7, 6322.4 +/- 1686.6 mg; P = .013, P = .001, P = .001, respectively). No significant difference in factor V Leiden, prothrombin G20210A, and MTHFR C677T mutations was observed between the osteonecrotic and control groups (P > .05). In conclusion, an association between the first year (3, 6, and 12 month) cumulative corticosteroid dosages and AVN was demonstrated in renal transplant recipients. However, no correlation was determined between factor V Leiden, prothrombin G20210A, and MTHFR C677T mutations and osteonecrosis.

RESUMO

BACKGROUND: Obesity is increasing in Turkey. The first experience with vertical banded gastroplasty (VBG) with regular intermediate-term follow-up in the Aegean Region of Turkey is presented. METHODS: From November 1993 to August 1999, 40 morbidity obese patients underwent VBG. The patients were evaluated on the basis of excess weight loss (EWL) and satisfaction with the operation. RESULTS: Regular follow-up was obtained in 38 patients (95%), with mean follow-up 27.2 months (14-85). Average preoperative body weight (BW) was 141.4 kg (93-238) and body mass index (BMI) was 52.3 kg/m2 (41-77.8). Average EWL was 64.1% (21.2-92.3). Average postoperative BW and BMI were 93.3 kg (70-145) and 34.4 kg/m2 (25.1-53) respectively. 35 of 38 patients (92%) lost more than 25% of EW and 28 of 38 (73.6%) lost more than 50% of EW. After weight loss, hypertension disappeared or improved in 86% of patients and diabetes resolved in 75%. Sleep apnea disappeared in 100% of patients. The early and late complication rates were 7.9% and 15.8% respectively. 33 of 38 patients (87%) were satisfied with the operation. CONCLUSION: VBG was safe and effective, resulted in acceptable weight loss, and the vast majority of patients were satisfied.

RESUMO

In a series of 9,312 women who consulted one of the authors with a complaint of disease of the breast between 1959 and 1991, nipple discharge was the presenting symptom in 448 (4.8 percent). Nipple discharge was spontaneous in 243 (2.6 percent) and provoked in 205 (2.2 percent) of the patients. The ages of the patients ranged from 13 to 75 years (mean of 42.5 years) in the spontaneous and 16 to 70 years (mean of 37.8 years) in the provoked discharge group. When a palpable mass was found, biopsy was undertaken, while in instances of nipple discharge only, subareolar exploration was performed. Of the 115 patients in the spontaneous and 25 patients in the provoked groups who underwent biopsy, the most frequent cause of nipple discharge was intraductal papilloma (47.8 percent). Nipple discharge was the result of carcinoma in 35 patients (14.4 percent) in the spontaneous and six patients (2.9 percent) in the provoked group, respectively. In patients with a palpable mass, the incidence of carcinoma was 61.5 percent compared with 6.1 percent in patients with nipple discharge only. Patients presenting with nipple discharge should undergo biopsy or subareolar exploration based on the presence or absence of a palpable tumor. The patients in whom no clinical findings could be detected should have follow-up evaluation at regular intervals.

RESUMO

The clinical and histological appearance of gingiva was evaluated in renal transplant recipients (RTR) receiving immunosuppressive drugs, in patients with chronic renal failure (CRF) undergoing hemodialysis, and systemically healthy individuals with periodontitis. Although the amount of bacterial plaque accumulation was similar among the groups (P greater than 0.05), the gingival inflammation was significantly less in RTR when compared to the other 2 groups (P less than 0.05). In light microscopic investigation the overall appearance of the connective tissue was similar in all of the groups. A mononuclear cell infiltration was present in all of the specimens; however, the number of inflammatory cells in patients with periodontitis was significantly higher than the other 2 groups (P less than 0.05). Prominent epithelial changes in the superficial layers of the oral epithelium; i.e., areas showing desquamation-like appearance, were noticed in patients with CRF. In electron microscopic investigation, fibroblasts and plasma cells with well-developed granular endoplasmic reticulum were found in connective tissue in RTR patients. In patients with CRF, epithelial cells presented swollen granular endoplasmic reticulum cisternae resembling vacuoles, indicating the presence of degeneration. It was suggested that with the use of immunosuppressive drugs the response to bacterial plaque did not diminish completely.

RESUMO

CD44 is a type I transmembrane glycoprotein serving as a cell adhesion receptor, whose main ligand is hyaluronic acid, but also may interact with collagen, laminin, fibronectin, and osteopontin. This marker is involved in cell migration, homing, activation, metastasis, and inflammation. Tubular CD44 expression has been shown to correlate with scarring in renal diseases, but there is little data on allograft biopsies. This deficiency is important since experimental studies have shown that blockade of the CD44-hyaluronic acid interaction may prolong allograft survival. In an attempt to clarify the role of tubular CD44 expression in renal allografts, CD44 expression was determined immunohistochemically in 37 allograft and 10 implantation biopsies, as the percentage of tubules expressing this marker. For implantation biopsies the mean tubular CD44 expression was 6% +/- 14%; for allograft biopsies, 13% +/- 20% (P =.17, Mann-Whitney U). By the Spearman correlation test, CD44 expression did not correlate with Banff scores, but was moderately correlated with serum creatinine values at the time of biopsy (P =.017, r =.4). These findings suggest an important role of tubular CD44 expression in renal allografts. It appears to be induced by more than one pathway, resulting in a pattern of expression that correlated with renal function. However larger series are required before recommending the routine use of this marker.

RESUMO

To investigate the parameters affecting systemic blood pressure in pediatric renal transplant recipients, we retrospectively examined the data from 19 adolescent renal transplant recipients including 6 girls overall, mean age of 15,47 +/- 3.56 years. Serum creatinine (Scr), fractional extraction of sodium (FENa), whole blood trough cyclosporine(C0), plasma total cholesterol (TC) and triglyceride levels, and systolic and diastolic blood pressure (SBP and DBP) were monitored during a total of 677 visits. SBP and DBP, classified as <95p (groups 1s and 1d) and >95p (groups 2s and 2d), were correlated with differences between groups 1 and 2. Group 2s Scr and FENa levels were higher than group 1s (P =.002 and P =.048, respectively), whereas C0 and FENa levels were higher in Group 2d than Group 1d (P = 0.028 and P = 0.036, respectively). Among the entire group, SBP and DBP positively correlated with C0; Scr and SBP, with FENa. While there was a positive correlation between SBP and C0 in groups 1s and 2s (r = 0.188, P <.000; and r = 0.145, P =.040), DBP was only associated with C0 in group 1d (P =.03, r = 0.156). In contrast, DBP showed a positive correlation with Scr in group 2d (P =.023, r = 0.132), and SBP with Scr in Group 1s. C0 and Scr levels were correlated in Groups 1s, 1d and 2d. At high BP levels (>95p), SBP is mostly affected by C0; DBP, with Scr. However, in both groups these two parameters positively correlate with each other. Thus, in adolescent renal transplant recipients the cause of high blood pressure does not appear to be solely related to cyclosporine related to induced allograft dysfunction.

RESUMO

Because of the inadequate numbers of organ donors, transplant surgeons are obliged to search for new horizons. Also, traditional beliefs are changing. The shortage of organs for transplantation, has led us to try certain arrangements so that suitable elderly organ donors may be included, as in many other transplant centers. We have now done 34 kidney transplantations from living related donors, who were 60 years of age and older. Donor-specific transfusions and low-dose triple drugs were used for all recipients. The overall patient survival was 97.5% and graft survival was 85.29%. In the light of these results we conclude that elderly living donor kidneys can be used satisfactorily with low-dose triple therapy.
