This study shows that a substantial majority of sickle cell patients live with pain on a regular basis and that there is substantial CAM use in the adult Sickle cell disease population. Being female and having a high school or higher education were significantly correlated with the use of CAM in sickle cell patients. A variety of CAM therapies are used, with the most common being prayer.

BACKGROUND: Chronic non-cancer pain (CNCP) is highly prevalent in older adults and long-term opioid therapy (LTOT) has been used to manage chronic pain. However, the safety of LTOT among older adults with CNCP is not well-established and there is a need to identify therapyrelated risk factors of opioid-related adverse events among older adults. OBJECTIVE: To evaluate the relationship between opioid dose and formulation and the risk of opioid-related adverse events among Medicare-eligible older adults on LTOT. DESIGN: Nested case-control study. PARTICIPANTS: Older Medicare beneficiaries (N=35,189) who received > 3 opioid prescriptions with a total dayssupply of >45 days within a 90-day period for CNCP between 2012 and 2016. MAIN MEASURES: This study utilized Medicare 5% medical and prescription claims data. Outcome measures included opioid-induced respiratory depression (OIRD), opioid overdose, all-cause mortality, and a composite outcome, defined as the first occurrence of any of the previous three events. Key independent variables were opioid formulation and opioid dose (measured in morphine milligram equivalents (MME)) prescribed during LTOT. KEY RESULTS: Seventy-four OIRD, 133 overdose, 982 all-cause mortality, and 1122 composite outcome events were observed during follow-up. In unadjusted analyses, the use of combination opioids (OR: 4.52 [95%CI: 1.51-13.47]) was significantly associated with OIRD compared to short-acting (SA) opioids. In adjusted analyses, opioidrelated adverse events were significantly associated with the use of LA (overdose OR: 13.00 [95%CI: 1.30-130.16] and combination opioids (overdose OR: 6.27 [95%CI: 1.91-20.55]; mortality OR: 2.75 [95%CI: 1.87-4.04]; composite OR: 2.82 [95%CI: 2.01-3.96]) when compared to SA opioids. When compared to an average dose of less than 20 MME, outcomes were significantly associated with doses of 20-50 MME (mortality OR

Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are overlapping manifestations on a spectrum of acute drug-induced conditions associated with severe blistering, skin peeling, and multi-organ damage. TEN is an eruption resembling severe scalding, with ≥30% skin detachment. SJS is a mild form of TEN, characterized histologically by epidermal keratinocyte apoptosis with dermo-epidermal separation and extensive small blisters with <10% body surface skin detachment. The syndrome can be induced by numerous medications and typically occurs 1–4 weeks after the initiation of therapy. Granulysin is found in the lesions of patients with SJS/TEN and plays a significant pathogenic role in the condition, but the overall mechanisms linking medications, granulysin, and disease manifestations remain obscure. This paper reviews evidence suggesting that the different medications implicated in SJS/TEN have the common property of interacting and synergizing with endogenous retinoids (vitamin A and its congeners), in many instances causing the latter to accumulate in and damage the liver, the main storage organ for vitamin A. It is hypothesized that liver damage leads to the spillage of toxic retinoid compounds into the circulation, resulting in an endogenous form of hypervitaminosis A and cytotoxicity with widespread apoptosis, mediated by granulysin and recognized as SJS/TEN. Subject to testing, the model suggests that symptom worsening could be arrested at onset by lowering the concentration of circulating retinoids and/or granulysin via phlebotomy or plasmapheresis or by pharmacological measures to limit their expression.
