Excellent chat with many thought provoking comments.
Hosted ably by Gates and Matt Graham-Brown

NephJC needs your help. Time to open your wallet and help keep the lights on at NephJC HQ. Also score some pretty fly NephJC fleece, hats and tote bags. (Yeah, we know that there has never been a “fly” tote bag. Work with us.
The NephJC Kidneys return for the fourth year. Time for #NephTwitter to nominate their favs.
Some cases of ADTKD are due to mutations of the MUC-1 gene, one mutation is a frame shift mutation that results in a premature stop codon. which results in accumulation of the abnormally short, and toxic protein MUC-1 fs . The researchers found a small protein, BRD4780, that reroute MUC-1fs to lysosomes, preventing proteinopathy and possibly altering the natural history of the disease.
This week is a joint #DermJC and #NephJC. We will discuss two articles - here is the summary of the larger case series, from Vandana Niyyar.
This week, we will discuss a perspective peice looking at the use of race in the eGFR formulas routinely used in the hospital. #NephJC chat.
We missed posting the wrap up on this one!
Here are the transcripts
We had two good chats in the shadow of the impending Holiday vacation. Here are the summaries:
We had some great discussion about the trial - and its applicability. Featured input from vascular surgery, anesthesia - and first author Emma Aitken!
Resistant hypertension is an important clinical problem. It is commonly defined as inadequate blood pressure control despite use of three antihypertensive agents of different classes at optimal dosages; one of the three should be an appropriately dosed diuretic. About 10-15% of hypertensive patients have resistant hypertension.
The magical powers of aldosterone antagonists first started to be publicized in the late 90's and in 2003 Calhoun showed a dramatic effect among patients with resistant hypertension:
This was backed up by additional observational data as part of the ASCOT trial experience. The investigators found dramatic efficacy from modest doses of spironolactone among the 1,411 patients that received spironolactone as a fourth line agent:
The first randomized, placebo controlled trial in resistant hypertension was published in 2011. The ASPIRANT trial (PDF) showed a more modest, but still clinically significant reduction blood pressure.
An important caution when looking at spironolactone data is that it appears that black patients are more sensitive to increases in aldosterone, so one could predict more modest blood pressure improvements with spironolactone in a European population. See Tu et al. (Full text).
Another critical aspect of resistant hypertension is addressing non-adherence.
This is why PATHWAY-2's attempt to measure minimize non-adherence is so important.
This week's chat on PATHWAY-2 represents the first randomized controlled trial against an active control group. The fact that aldosterone rises above other fourth line agents to provide meaningful advantages in the treatment of resistant hypertension is important.
We are coming to a new age in hypertension management. On November 9, at 2:00 PM at the AHA meeting in Orlando the SPRINT Trial results will be released. This will almost certainly result in a wave of more aggressive blood pressure control. Almost simultaneously we now have access to the first of the next generation potassium binders, patiromer. This brings the hope of avoiding the most frightening of the side effects from aldosterone antagonists, hyperkalemia. These three seemingly unrelated events are going to be major influences on the treatment of hypertension going forward.
