ABSTRACT
Bone disease is highly prevalent in patients with chronic kidney disease (CKD), leading to an increased risk of bone fractures. This is due in part to metabolic acid-induced bone dissolution. Bisphosphonates (BPPs) are a potential treatment for inhibiting bone dissolution; however, there are limited studies observing the use of BPPs on acidotic patients. We aimed to determine efficacy of BPPs on maintaining bone health and pH regulation in acid-exposed mice. Using a diet-induced murine model of metabolic acidosis, we examined bone structure, composition, and mechanics as well as blood gases for three groups: control, acidosis, and acidosis + bisphosphonates (acidosis+BPP). Acidosis was induced for 14 days and alendronate was administered every 3 days for the acidosis+BPP group. The administration of BPP had little to no effect on bone structure, mechanics, and composition of the acidosis bones. However, administration of BPP did cause the mice to develop more severe acidosis than the acidosis only group. Overall, we discovered that BPPs may exacerbate acidosis symptoms by inhibiting the release of buffering ions from bone. Therefore, we propose that BPP administration should be carefully considered for those with CKD and that alkali supplementation could help minimize acidifying effects.

Hypocomplementemia urticarial vasculitis syndrome (HUVS) is a rare form of systemic vasculitis which is characterized by the presence of urticaria and hypocomplementemia. The presence of recurrent and chronic urticarial rash is the dominant clinical finding in HUVS. Other manifestations including angioedema, arthritis, gastrointestinal symptoms, ocular inflammation, pulmonary involvement, renal involvement, and central nervous system involvement are also seen. Although the pathophysiology of HUVS is yet to be fully understood, it has been demonstrated that immune complex-mediated injury is the predominant mechanism responsible for severe systemic manifestations; a mechanism of injury similar to systemic lupus erythematosus (SLE). HUVS shared many clinicopathological features with SLE and it is prudent to question whether HUVS is a separate disease entity or SLE in evolution. Herein we present a case of a male patient who was diagnosed with SLE a year after being diagnosed with HUVS.

BACKGROUND: Given the importance of inflammation as a predictor of poor outcomes in End Stage Renal Disease (ESRD), reductions in inflammatory biomarkers have been proposed as a critical target in this population. This study targets chronic periodontitis, an oral inflammatory disease of microbial etiology causing persistent inflammation in ESRD. Unlike the previously reported episodic periodontal interventions, we propose to control periodontal inflammation with a continuous maintenance and oral health behavior modifications. We hypothesize that this strategy will improve systemic inflammation and oxidative stress, oral health and quality of life within the 6-month observation period. METHODS: The rePAIR (novel PAradigm to improve Inflammatory burden in ESRD) study is a pilot and feasibility, parallel-arm, and randomized controlled clinical trial that will recruit 72 ESRD subjects with periodontitis in a model of computerized block randomization. This trial aims to compare the effect of standard-of-care vs. repeated non-surgical periodontal therapy on systemic and oral inflammatory burden. This trial will recruit ESRD adult patients with periodontitis older than 21 years old with a minimum of 12 teeth and no history of periodontal treatment within a year. The trial will examine serum C-reactive protein (CRP) (primary outcome) as a biomarker of inflammation as well as interleukin-6 (IL-6), F2 isofurans and F2 isoprostanes (secondary outcomes) and compare their difference between groups from baseline to 6 months. The trial will also compare the difference between groups in patient-centered and clinical oral outcomes from baseline to 6 months. DISCUSSION: The trial follows a rigorous and transparent study design capturing elements such as pre-specified eligibility criteria, pre-specified primary and secondary outcomes, detailed intervention description to allow replication, intervention random allocation and concealment, blinding in outcome assessment, appropriate sample size calculations, explanation of interim analysis, as per CONSORT Guidelines. Further, gender diversity is secured not only at recruitment but also throughout the trial and during the analysis. Therefore, treatment response outcomes will be examined per gender category. In order to manage anticipated problems, the protocol has included alternative approaches. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03241511 . Registered on 7 August 2017.

Dietary supplements are commonly used by patients as part of their medical care plan. Often clinicians may not be aware of their use, because patients do not always consider these to be medications. All clinicians need to continually ask patients about their use of dietary supplements when collecting a medication history. Dietary supplements and prescription medications often share similar enzymatic pathways for their metabolism. These interactions may lead to severe adverse reactions. This article reviews available evidence for a variety of dietary supplements in select disease categories.

Propofol related infusion syndrome (PRIS) is a rare, but extremely dangerous complication of propofol administration. Unexplained anion-gap metabolic acidosis, rhabdomyolysis, hyperkalemia, acute kidney injury, elevated liver enzymes, and potentially fatal cardiac arrhythmias are characteristic of PRIS. Risk factors for the develop- ment of PRIS include dose and duration of propofol infusion, severe illness, and concomitant administration of catecholamine and glucocorticoids. PRIS causing hyperkalemia is a well-known clinical entity. Although the development of PRIS depends on the duration and total amount of drug infused, repeated boluses of propofol, commonly used for rapid sequence intubation and conscious sedation, can potentially precipitate fatal hyperkalemia. This is of particular concern in advanced chronic kidney disease (CKD) and end stage renal disease (ESRD) patients. We report a case of a propofol induced hyperkalemia causing near fatal cardiac arrhythmia in a dialysis dependent ESRD patient. We report successful revival from cardiac arrest by intensive calcium regimen and hemodialysis. This case highlights underrecognized problem of propofol-induced hy- perkalemia, which can be of particular concerns in advanced CKD and ESRD.

Thyrotoxic Hypokalemic Periodic Paralysis (THPP) is a rare complication of thyrotoxicosis and can sometimes be fatal. It needs early recognition for proper management and prevention of recurrences. Here we describe two cases presenting with acute onset of paresis, low potassium levels, low levels of thyroid-stimulating hormones (TSH), and elevated thyroid hormone levels.
