Journal Club: Dry weight adjustment in dialysis

Agarwal continues his streak of important studies on blood pressure in dialysis patients. This study shows that reducing the dry weight results in reductions in ambulatory blood pressures done between dialysis sessions. Agarwal had previously demonstrated that in-center blood pressure readings poorly correlated with ambulatory blood pressure. One of the key findings was that the systolic fell twice as much as the dialtolic blood pressure. This means they did not only reduce the blood pressure but they also reduced the pulse pressure, something which we really are unable to do with antihypertensive drug therapy (which reduces both the systolic and diastolic blod pressure and have little affect on the pulse pressure).

Personal note: Agarwal was one of my attendings when I was a resident and wrote one of my letters of recommendation for fellowship.
