Identifying Hemodialysis Patients With the Highest Risk of Staphylococcus aureus Endogenous Infection Through a Simple Nasal Sampling Algorithm.

In contrast to Staphylococcus aureus intermittent nasal carriers, persistent ones have the highest risk of infection. This study reports the usefulness of a simple nasal sampling algorithm to identify the S. aureus nasal carriage state of hemodialysis patients (HPs) and their subsequent risk of infection.

Predicting the risk for dialysis or death in IgA nephropathy.

For the individual patient with primary IgA nephropathy (IgAN), it remains a challenge to predict long-term outcomes for patients receiving standard treatment. We studied a prospective cohort of 332 patients with biopsy-proven IgAN patients followed over an average of 13 years. We calculated an absolute renal risk (ARR) of dialysis or death by counting the number of risk factors present at diagnosis: hypertension, proteinuria ≥1 g/d, and severe pathologic lesions (global optical score, ≥8).

Significant risk factors for occurrence of cancer after renal transplantation: a single center cohort study of 1265 cases.

Occurrence of cancer after renal transplantation remains a major problem, and the second cause of death. We performed a retrospective analysis of first cancer, first skin cancer, and first organ cancer (including posttransplant lymphoproliferative disease [PTLD]) among 1265 cases from 1979 to 2006. The occurrence of cancer was clearly a time-dependent event justifiying the use of Kaplan-Meier survival and Cox regression methods.

Natural history of primary IgA nephropathy.

Primary IgA nephropathy (IgAN) is the most frequent type of primary glomerulonephritis worldwide. The characteristic presentation is gross hematuria at the time of an infectious episode. A renal biopsy still is mandatory for the diagnosis.
