Crystalline Nephropathy in Renal Transplant: A Series of 4 Cases.

Crystals are particles of endogenous inorganic or organic composition that can trigger kidney injury when deposited or formed inside the kidney. The most common forms of crystalline nephropathies (CNs) are nephrocalcinosis and oxalate nephropathy. The causes of early allograft dysfunction are changing constantly, and recently calcium oxalate (CaOx) crystal deposition has been added to this list.

Angiogenic activity in the sera of patients with post-kidney transplant erythrocytosis.

Post-kidney transplant erythrocytosis (PTE) is one of the hematological complications in the renal transplant patients. While its pathogenesis still remains to be elucidated completely, a number of therapies are available for the management of PTE. The aim of this prospective study was to investigate whether angiogenesis may be involved in the pathogenesis of post-transplant erythrocytosis by comparing its level with those of different classes of erythrocytosis [polycythemia vera (PV), idiopathic erythrocytosis and secondary erythrocytosis].

BK virus-associated hemophagocytic syndrome in a renal transplant recipient.

Hemophagocytic syndrome (HPS) is a life-threatening hematological disorder in immunocompromised patients. Reactive HPS is observed in patients with systemic infection, neoplasia or auto-immune diseases. It is a rare hematological disorder after renal transplantation and must be suspected when fever and pancytopenia are seen in association with viral infections.

Secondary oxalosis due to excess vitamin C intake: a cause of graft loss in a renal transplant recipient.

Renal oxalate deposition can be seen with primary hyperoxaluria, malabsorptive states, ethylene glycol toxicity and, rarely, with excessive vitamin C ingestion. We report a case of secondary hyperoxaluria in which the diagnosis was not considered initially because there was no past history of urinary calculi and no evidence of nephrocalcinosis on plain X-ray of the abdomen and ultrasonography. The disease was detected and diagnosed only after kidney transplantation.

Living and cadaver donor transplant programs in the Maghreb.

In the Maghreb, organ failure constitutes a major public health problem, especially given the increasing number of patients with chronic renal failure and the high cost of care. In this study, we attempted to seek the recommendations, through a questionnaire, of various officials related to organ transplantation as well as leaders of ethics committees and religious groups in different countries of the Maghreb. The objective was to improve the rate of organ donation and transplantation.

Atypical presentation of a brown tumor in a kidney transplant recipient: a case report.

Brown tumor is a rare complication of secondary hyperparathyroidism. It is exceptionally encountered after kidney transplantation. We here report on a 54-year-old male recipient who developed a brown tumor localized in the right forearm, and whose initial presentation was atypical, mimicking a bone tumor.

Sirolimus for the treatment of Kaposi sarcoma after renal transplantation: a series of 10 cases.

The incidence of Kaposi sarcoma (KS) has substantially increased among immunocompromised patients, suggesting a role for immunosuppressive drugs. The aim of this study was to evaluate the incidence, features, and outcome of KS among 307 kidney transplantation patients at our center between January 1994 and June 2010. During the study period, the 10 patients who developed KS (3.

Atypical presentation of cutaneous leishmaniasis in a renal transplant recipient successfully treated with allopurinol and fluconazole.

Leishmaniasis is a zoonotic infection acquired through the bite of a female sandfly, which introduces the amastigotes of Leishmania into the bloodstream. Cutaneous leishmaniasis is rare after solid organ transplantation. Its diagnosis is difficult in immunosuppressed patients.

Early onset of paucisymptomatic cryptococcal meningitis in a kidney transplant patient: a case report and review of the literature.

Fungal infections of the central nervous system are rare and are more frequently encountered in immunocompromised patients. Cryptococcocal infection is the most common opportunistic fungal infection after Candida and Aspergillus in organ transplant recipients. Atypical manifestations and nonspecific neuroradiological findings due to the lack of inflammatory response in these immunocompromised patients are responsible for a delay in diagnosis.

Primary adenocarcinoma in a kidney allograft: a case report and review of the literature.

De novo tumors are common complications after solid organ transplantation. Lymphoma and skin cancers are the most frequently observed malignancies. However, graft carcinomas can be observed to be five times more frequent after kidney transplantation compared to their incidence in the general population.

Evolution of impaired renal function after external continent urinary diversion (Mitrofanoff principle).

Objective: To study the evolution of impaired renal function after external continent urinary diversion (Mitrofanoff principle) (ECUD-M) associated with ileocystoplasty.

Patients And Methods: Over 18 years from 1992 to 2009, ECUD-M with ileocystoplasty was performed in 120 patients with mean age of 25.5 years.

Simultaneous Hodgkin's disease and Kaposi sarcoma in a renal transplant recipient.

A 38-year-old women underwent first cadaver kidney transplantation. Her panel reactive antibody was 0%, and she had never previously been transfused nor pregnant. She received induction therapy with antithymoglobulin (ATG) as standard protocol and maintained on immunosuppressive treatment of cyclosporine A, mycophenolate mofetil (MMF), and prednisone.

Factors predisposing to post-renal transplant erythrocytosis: a retrospective study.

A retrospective study was conducted on 143 consecutive renal transplant recipients who had a functioning graft for three months or longer, to evaluate the prevalence of post-transplant erythrocytosis (PTE) and its potential risk factors. True PTE was defined as hematocrit (Ht) above 52% and hemoglobin (Hb) above 18 g/dl in males, and Ht above 50% and Hb above 17 g /dl in females. A total of 31 patients (21.

Successful treatment of post-renal transplant gastric and pulmonary Kaposi's sarcoma with conversion to rapamycin treatment.

The incidence of Kaposi's sarcoma (KS) is higher in organ transplant recipients. The lesions are mainly cutaneous and isolated visceral involvement is rare. We herewith report a 38-year-old male patient, who underwent a cadaveric donor renal transplantation for chronic interstitial nephropathy.

[Renal biopsy findings in diabetes mellitus].

Background: The prevalence of diabetic patients with endstage renal disease is increased overall the word. Renal biopsy is sometimes necessary to precise the type of renal damage.

Aim: To precise the type and the frequency of non diabetic nephropathy in diabetic patients.

Infection in kidney transplant recipients in Tunisia.

To determine the patterns of infectious complications in the renal transplant recipients in our center, we evaluated 18 patients (13 males and five females) who were transplanted between 1994-1998. The average age of the patients was 28 years. Sixteen (88%) and 2 (12%) transplants were from living-related and cadaver donors, respectively.

Asymptomatic gastric angiodysplasia in chronic hemodialysis patients: case reports.

Gastrointestinal (GI) angiodysplasia is a vascular lesion. It is a common cause of GI bleeding in chronic renal failure (CRF). We report three adult chronic hemodialysis patients with asymptomatic angiodysplasia.

Autosomal dominant Alport's syndrome: study of a large Tunisian family.

Alport's syndrome is a hereditary nephritis that may lead to end-stage renal disease (ESRD) in early adult life. It is a clinically and genetically heterogeneous nephropathy. Alport's syndrome is often associated with sensorineural deafness and/or ocular abnormalities.

Infectious complications in kidney transplant recipients: a single-center experience.

To determine the patterns of infectious complications in renal transplant recipients in our center, we evaluated 48 patients (29 men and 19 women) who were transplanted between 1994 and 2003. The average age of the patients was 29 years. Thirty (62.
