Acute Kidney Injury
Acute kidney injury (AKI) is a major therapeutic challenge. One of the potential reasons for this, is the difficulty in obtaining an adequate and comprehensive assessment of the renal function. I recently performed a study with my group where I evaluated markers of kidney tubular function to determine if patients with underlying kidney disease and decreased tubular function at baseline were at higher risk of acute kidney injury. I found that two markers of kidney tubular function at baseline can predict future risk of acute kidney injury secondary to hemodynamic changes among patients with chronic kidney disease. My currently goal is to determine if a broader panel kidney function markers are also able to detect future risk of AKI and to expand my currents findings to diverse forms of AKI.
Intradialytic hypotension is the most common complication during dialysis. It has been associated with cardiovascular disease, decreased cerebral blood flow, poor quality of life and it is an independent risk factor for mortality. Our work has demonstrated that decreasing the dialysate temperature in an individualized manner is not only an effective technique to decrease intradialytic hypotension, but it is also well tolerated.
Quality of Life Among Hemodialysis Patients
End stage renal disease or advanced kidney disease requiring dialysis is associated with depression, anxiety, sexual dysfunction and sleep which can impact health-related quality of life. Acupuncture and massage are complementary nonpharmacological interventions that have been used to manage symptoms of chronic illness and reduce their severity. Our work revealed that use of complementary therapies such as massage and acupuncture during hemodialysis may contribute toward improvement of health-related quality of life and thus should be considered when addressing overall health status of these patients.
