A 60-year-old HIV-1 infected woman on antiretroviral therapy (emtricitabine/tenofovir, and ritonavir-boosted atazanavir) developed Hodgkin's lymphoma. The patient initiated ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) chemotherapy and presented with neutropenia and severe hypokalemia. Hypokalemia was considered as part of a proximal tubular renal dysfunction, and other causes of hypokalemia were excluded. Due to suspicion of drug--drug interactions between antiretrovirals and vinblastine, ritonavir-boosted atazanavir was switched to dolutegravir and the patient continued emtricitabine/tenofovir...

OBJECTIVE: For evaluation of primary aldosteronism, international guidelines recommend a 4-6 week withdrawal of spironolactone, eplerenone, and amiloride prior to adrenal vein sampling (AVS). It is not always feasible to withdraw these drugs in patients with severe hypertension and hypokalemia. We present our experience evaluating the efficacy and clinical outcomes of a 2-week protocol for withdrawal of renin-stimulating antihypertensives prior to AVS. DESIGN: A single-center retrospective review of all patients who underwent AVS for primary aldosteronism between January 2014 and December 2015...

Protein kinase CK2 (CK2) is a highly promising target for cancer therapy and anti-CK2 gene expression therapy has shown effectiveness in rodent models of human head and neck cancer (HNC). To date, there has been no large animal model of cancer in which to further explore anti-CK2 therapies. Feline oral squamous cell carcinoma (FOSCC) has been proposed as a large animal model for human HNC and we have previously shown that CK2 is a rational target in FOSCC. We hypothesized that a novel tenfibgen coated tumor-specific nanocapsule carrying RNAi oligonucleotides targeting feline CK2α and CK2α' (TBG-RNAi-fCK2αα') would be safe in cats with FOSCC...

We report the case of a 41-year-old male patient with juvenile onset refractory hypertension while taking four drugs including a diuretic. Fourteen years before he underwent a complete investigation for secondary hypertension (including the aldosterone to renin ratio-ARR) that was negative. Since that, hypertension control gradually worsened, hypertensive organ damage aggravated and hypokalemia developed in spite of ACE inhibitor treatment. At the re-evaluation ARR was elevated, and the further workup for primary aldosteronism demonstrated an unilateral aldosterone producing adenoma that was surgically removed, with subsequent optimal blood pressure control with two anti-hypertensive drugs...

The diuretics are essential medicaments of antihypertensive therapy. They reduce blood pressure and cardiovascular events optimally. With increasing doses of thiazides and thiazide analogs do not come further powerful effect of reducing blood pressure or cardiovascular mortality and morbidity, but clearly elevate the side effects. Because of it, the minimum effective dose level and the fixed-dose combination therapy should be preferred. The use these drugs leads to especially positive outcome in elder patients, isolated systolic hypertension, heart failure, after stroke and in black population...
