The impact of delayed graft function (DGF) on the outcome of renal transplantation remains controversial. We analyzed the risk factors for DGF and its impact on graft and patient survival. A total of 354 renal transplants performed between June 1986 and April 2000 were analyzed. Variables analyzed included donor and recipient age, method and duration of renal replacement therapy, HLA mismatch, cold and warm ischemia times, biopsy-confirmed acute rejection, length of stay in the hospital, serum creatinine at the end of first hospitalization as well as graft and patient survival at one, three, five and ten years. The study patients were divided into two groups: patients with DGF (G1) and those without DGF (G2). DGF occurred in 50 patients (14.1%), and it was seen more frequently in patients transplanted from deceased donors (60% vs. 40%, P <0.0001). The cause of DGF was acute tubular necrosis, seen in 98% of the cases. Univariate analysis showed a statistically significant difference between the two groups G1 and G2 in the following parameters: average duration on dialysis (52.3 vs. 36.4 months, P = 0.006), HLA mismatch (44.9% vs. 32.11% P = 0.015), donor age (35.9 vs. 40.2 years, P = 0.026), cold ischemia time (23 vs. 18.2 h, P = 0.0016), warm ischemia time (41.9 vs. 38.6 mn, P = 0.046), length of stay in the hospital during first hospitalization (54.7 vs. 33.2 days, P <0.0001), serum creatinine at the end of first hospitalization (140 vs. 112 μmol/L, P <0.0001) and at three months following transplantation (159 vs. 119 μmol/L, P = 0.0002). Multivariate analysis revealed the following independent risk factors for DGF: deceased donor (RR = 13.2, P <0.0001) and cold ischemia time (RR = 1.17, P = 0.008). The graft survival at one, three, five and ten years was 100%, 93%, 88.3% and 78.3% in G1 versus 100%, 95.9% 92.8% and 82.3% in G2; there was no statistically significant difference. The patient survival at one, three, five and ten years was 100%, 91.3%, 83.6% and 74.4% in G1 versus 100%, 95.9%, 94% and 82.6% in G2 with a statistically significant difference (P = 0.04). Prolonged cold ischemia time and transplantation of kidneys from deceased donors were the main risk factors for DGF in our study. Also, DGF significantly affected patient survival but had no influence on graft survival.

The combination of surgery and rituximab achieved lasting pain relief with no recurrence of exophthalmos.

KS is the most post KT malignancy observed in our country and is characterized by a predominance of limited superficial forms.

Introduction: Mycophenolate Mofetil (MMF) is an immunosuppressive drug usually used in kidney transplants to prevent rejection. It has various adverse effects such as leucopenia, anemia, diarrhea but Mouth ulcers are rarely reported. Methods: We present a case report of MMF-induced mouth ulcers in an African patient. Case Report: A 41-year-old African-male patient has painful oral ulcers which developed 5 months after kidney transplantation. The immunosuppressive maintenance regimen comprised Steroids, Tacrolimus and MMF. Results: These ulcers were firstly related to a fungic or viral infection so the patient was prescribed Fluconazole and Aciclovir without any improvement. Then, Tacrolimus blood level was checked and it was in a therapeutic range. Finally, we decide to stop MMF and the ulcers healed quickly. Discussion: Oral ulcers are frequently seen complications in immunosuppressant patient but are rarely described with MMF. These ulcers can become large and very painful and degrade patient's life quality. So when infections causes are excluded, we have to keep in mind that these ulcers can be a drug adverse effect.

Th17 cell subset has been implicated in autoimmune diseases, tumor immunity and, transplant rejection. In order to investigate the role of IL-17/IL-23 pathway in allograft outcome, intragraft expression of IL-17 mRNA and single nucleotide polymorphisms (SNPs) of IL-17A, IL-17F, IL-17RC, and IL23R genes were evaluated with a quantification of IL-17A, IL-17F, and IL-23 plasma levels. This study revealed that recipients with acute rejection (AR) had a significant increase in IL-17A mRNA expression levels after transplantation compared to controls (P = 0.037). Moreover, IL-17A plasma levels were significantly higher in AR group; pretransplantation (Day-1 [D-1]): P = 0.00022 and posttransplantation (Day 7 [D7]): P < 10 . IL-17F and IL-23 plasma levels were significantly higher in AR at D7 only (47.86 vs. 22.99 pg/ml; and 33.82 vs. 18.811 pg/ml; P = 0.015 and P < 10 , respectively). Using receiver-operating characteristic curves, D7 IL-17A and IL-23 plasma levels exhibited excellent sensitivities and specificities for predicting AR. Genetic study revealed no association between IL-17A, IL-17F, IL-17RC, and IL23R studied SNPs and AR. Nevertheless, a significant improvement of graft survival was found in kidney transplant recipients carrying IL-17F-rs763780*A/A, IL-17RC*G/G, and *G/A genotypes. Besides, IL-17A mRNA levels were significantly higher in patients carrying the IL-23R*G/G genotype comparatively to those with *G/A genotype. Based on these findings, significant increase of IL-17A mRNA and protein levels in AR recipients that are genetically controlled highlights the role of this cytokine that can be a useful clinical biomarker to predict early acute renal allograft rejection.

The aim of this study is to evaluate the features of visceral leishmaniasis (VL) in adults with nephropathy, who were not infected with the human immunodeficiency virus. This is a retrospective study of 14 adults hospitalized between 2000 and 2014, with VL and renal involvement. Clinical, biological, and therapeutic data were collected from the patients' medical files. Eleven women and three men, most of whom were from the North of the country, with a mean age of 40.5 years were studied. Lupus was present in five cases, the Sicca syndrome in three cases, diabetes in one case, renal failure on dialysis in two cases, and there were three renal transplant recipients. Major clinical symptoms were fever and weakness in all cases. Enlargement of the spleen was present in eight cases and hepatomegaly in six cases. Biologic inflammatory syndrome and anemia were present in all cases, and pancytopenia was present in seven cases. Renal insufficiency was noted in all cases. Diagnosis of VL was confirmed by bone marrow examination or serology. Treatment consisted of antimoniate in 10 cases and amphotericin B in four cases. Seven deaths were recorded. Clinical symptoms of VL are atypical in patients with nephropathy and therefore, the diagnosis should be suspected in such patients because VL is still endemic in our country.
