Significance of Urinary Proteome Pattern in Renal Allograft Recipients

Urinary proteomics is developing as a platform of urinary biomarkers of immense potential in recent years. The definition of urinary proteome in the context of renal allograft and characterization of different proteome patterns in various graft dysfunctions have led to the development of a distinct science of this noninvasive tool. Substantial numbers of studies have shown that different renal allograft disease states, both acute and chronic, could portray unique urinary proteome pattern enabling early diagnosis of graft dysfunction and proper manipulation of immunosuppressive strategy that could impact graft prognosis. The methodology of the urinary proteome is nonetheless not more complex than that of other sophisticated assays of conventional urinary protein analysis. Moreover, the need for a centralized database is also felt by the researchers as more and more studies have been presenting their results from different corners and as systems of organizing these newly emerging data being developed at international and national levels. In this context concept of urinary proteomics in renal allograft recipients would be of significant importance in clinical transplantation

Could peak proteinuria determine whether patient with dengue fever develop dengue hemorrhagic/dengue shock syndrome? - A prospective cohort study

BACKGROUND: Worldwide there is a need to develop simple effective predictors that can distinguish whether a patient will progress from dengue fever (DF) to life threatening dengue hemorrhagic (DHF) or dengue shock syndrome (DSS). We explored whether proteinuria could be used as such a marker. METHODS: We included patients admitted to hospital with suspected dengue fever. Starting at enrollment until discharge, each patient's daily spot urine protein creatinine ratio (UPCR) was measured. We classified those with confirmed dengue infection as DF or DHF (including DSS) based on WHO criteria. Peak and day of onset of proteinuria was compared between both groups. RESULTS: Compared to those with DF, patients with DHF had significantly higher median peak proteinuria levels (0.56 versus 0.08 g/day; p < 0.001). For patients with DHF, the median day of onset of proteinuria was at 6 days of defervescence, with a range of -2 to +3 days after defervescence. There were three patients with DF who did not have proteinuria during their illness; the five remaining patients with DF had a median day of onset of proteinuria of was at 6 days of defervescence with a range of 0 to +28 days. CONCLUSIONS: Peak UPCR could potentially predict DHF in patients with dengue requiring close monitoring and treatment
