[Oxalate nephropathy due to malabsorption syndrome].

Enteric oxalate nephropathy is caused by hyperoxaluria. Factors which contribute to excessive oxalate absorption are an abundance of free fatty acids in the intestine due to malabsorption, changes in the microbiome, and bowel inflammation. We present two cases that illustrate different pathophysiological aspects of this disease.

Total Laparoscopic Colocolpopoiesis in a Kidney Transplant Recipient With Frasier Syndrome.

Background: The absence of a normal functioning vagina can have a profound impact on women's quality of life and psychological well being. Frasier syndrome is a rare autosomal recessive disorder which presents with male pseudohermaphroditism with gonadal dysgenesis, renal failure in early adulthood and increased risk of developing gonadoblastoma. Kidney transplant recipients are reported to have a high complication rate after colorectal surgery, most probably resulting from immunosuppressive therapy.

Dutch guidelines for diagnosis and therapy of proliferative lupus nephritis.

Proliferative lupus nephritis is a strong predictor of morbidity and mortality in patients with systemic lupus erythematosus. Despite improvements in the management of lupus nephritis, a significant number of the patients do not respond to immunosuppressive therapy and progress to end-stage renal failure. In order to optimise the diagnostic strategy and treatment of patients with proliferative lupus nephritis, guidelines are needed.

Circulating lymphocyte subsets in different clinical situations after renal transplantation.

Phenotypic characterization of T and B lymphocytes allows the discrimination of functionally different subsets. Here, we questioned whether changes in peripheral lymphocyte subset distribution reflect specific clinical and histopathological entities after renal transplantation. Sixty-five renal transplant recipients with either histologically proven (sub)clinical acute rejection or chronic allograft dysfunction, or without abnormalities were studied for their peripheral lymphocyte subset composition and compared with 15 healthy control individuals.
