Critères d’indications de la biopsie rénale chez les patients diabétiques de type 2 protéinuriques : enquête auprès des néphrologues français

National audienceDiabetic nephropathy is usually a presumptive diagnosis based on clinical and biological evidence. Renal biopsies are performed in diabetic patients with atypical findings evoking non-diabetic renal disease who could benefit from specific therapies. French speaking nephrologists were asked which criteria they retain to indicate renal biopsy in patients with type 2 diabetes and albuminuria>0.5g/day or equivalent through an online anonymous questionnaire. Among the suggested criteria were absence of diabetic retinopathy, hematuria, rapid decrease in GFR, short diabetes duration or rapid raise of proteinuria. 188 people answered the poll among whom interns (12%), fellows (13%), university hospital practitioners (26%), general hospital practitioners (24%), practitioners in a non-profit organization (13%), practitioners on private activity (10%), multi-modal practitioners (3%) and people without clinical activity (2%). Increasing proteinuria was retained as an indication criterion for renal biopsy by 51% of respondents, nephrotic syndrome by 56% of respondents, absence of diabetic retinopathy by 57% of respondents, short diabetes duration by 65% of respondents, rapid GFR decline by 75% of respondents and hematuria by 78% of respondents. These data highlight the high diversity of opinions on this topic and their discrepancies with guidelines and current literature regarding the association between non-diabetic renal disease and clinical and biological features. The lack of adhesion of nephrologists to guidelines was especially noteworthy regarding the absence of diabetic retinopathy. These results emphasize the need for studies focusing on biopsy indication criteria in patients with type 2 diabetes

Unexpected overdose of oral cyclosporine in a kidney transplant patient: a case report

International audienceCyclosporine is a widely used immunosuppressive agent to prevent rejection of solid organ transplant. Here, we describe the case of a 71-year-old man who received the prescribed dose of cyclosporine 10 times 6 days after a kidney transplantation because of a concentration miscalculation involving two galenic forms. The patient presented gastrointestinal and neurological disorders. Therapeutic drug monitoring revealed high cyclosporine blood concentrations (693 ng/mL, therapeutic range 100-300 ng/mL). Symptomatic management of digestive disorders was performed, and haemodialysis was started the day after the cyclosporine overdose in the face of acute renal failure. The patient’s disorders were quickly resolved. The dosing regimen was adapted in order to administer the most appropriate galenic form and to avoid another administration error. Long-term follow-up showed no failure of renal transplantation. The purpose of this case report is to warn physicians and clinical pharmacists about the vigilance required on cyclosporine prescription, especially when two galenic forms are administered to obtain the prescribed dose

Maternal, foetal and child consequences of immunosuppressive drugs during pregnancy in women with organ transplant: a review

International audienceAlthough pregnancy remains exceptional in women after heart, liver or lung transplant, obstetricians and nephrologists are regularly confronted with pregnancy in renal transplant recipients. National and international registries have described the epidemiology of maternal, foetal and neonatal complications, and transplantation societies have published recommendations on the monitoring of these high-risk pregnancies. In this review, we summarize the existing data on maternal and foetal complications of pregnancies in women after renal transplant, especially the management of immunosuppression. We also describe the few available data on the middle- and long-term outcomes of their children who were exposed in utero to immunosuppressive drugs
