Abstract
Vaso-occlusive crises (VOC) is common and opioids are the treatment of choice.This study compared parenteral pethidine and morphine in the elimination/reduction of pain in acute VOC to tolerable levels. This open-label randomized study compared intravenous morphine 5 mg 4 hourly to intramuscular pethidine 75 mg 4 hourly. Eighty-two consenting adult sickle cell disease participants were recruited from the Korle-Bu Polyclinic. (Forty-one participants in each arm). There were 42 male and 40 female participants. Median age was 25 years. Pethidine participants totalling 31.7% (13/41) and 53.7% (22/41) in the morphine arm had a sustained response within 6 h, p = 0.027. In the pethidine and morphine arms 60.0% (24/40) and 62.5% (25/40) of participants respectively achieved adequate pain control within 72 h of initiating therapy, p = 0.296. Most participants, 96.3% (79/82) had no side effects to opioids. The commonest side effects were generalized pruritus, nausea and vomiting, and headaches. More pethidine than morphine participants experienced side effects 29.3% and 22.0% respectively; p = 0.448. In conclusion, more morphine participants achieved a sustained pain response compared to the pethidine participants. There was no difference in the tolerability and side effect profile of the opioids. No participant experienced respiratory suppression.

Inhibition of DAGLβ as a therapeutic target for pain in sickle cell disease. Haematologica 2023; 108:859-869.

Abstract
Sickle cell disease (SCD) is the most common inherited disease. Pain is a key morbidity of SCD and opioids are the main treatment but their side effects emphasize the need for new analgesic approaches. Humanized transgenic mouse models have been instructive in understanding the pathobiology of SCD and mechanisms of pain. Homozygous (HbSS) Berkley mice express >99% human sickle hemoglobin and several features of clinical SCD including hyperalgesia. Previously, we reported that the endocannabinoid 2-arachidonoylglycerol (2-AG) is a precursor of the pro-nociceptive mediator prostaglandin E2-glyceryl ester (PGE2-G) which contributes to hyperalgesia in SCD. We now demonstrate the causal role of 2-AG in hyperalgesia in sickle mice. Hyperalgesia in HbSS mice correlated with elevated levels of 2-AG in plasma, its synthesizing enzyme diacylglycerol lipase β (DAGLβ) in blood cells, and with elevated levels of PGE2 and PGE2-G, pronociceptive derivatives of 2-AG. A single intravenous injection of 2-AG produced hyperalgesia in non-hyperalgesic HbSS mice, but not in control (HbAA) mice expressing normal human HbA. JZL184, an inhibitor of 2-AG hydrolysis, also produced hyperalgesia in non-hyperalgesic HbSS or hemizygous (HbAS) mice, but did not influence hyperalgesia in hyperalgesic HbSS mice. Systemic and intraplantar administration of KT109, an inhibitor of DAGLβ, decreased mechanical and heat hyperalgesia in HbSS mice. The decrease in hyperalgesia was accompanied by reductions in 2-AG, PGE2 and PGE2-G in the blood. These results indicate that maintaining the physiological level of 2-AG in the blood by targeting DAGLβ may be a novel and effective approach to treat pain in SCD.

Comparing the Effectiveness of Education Versus Digital Cognitive Behavioral Therapy for Adults With Sickle Cell Disease: Protocol for the Cognitive Behavioral Therapy and Real-time Pain Management Intervention for Sickle Cell via Mobile Applications (CaRISMA) Study. JMIR Res Protoc 2021; 10:e29014. [PMID: 33988517 PMCID: PMC8164118 DOI: 10.2196/29014] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 03/29/2021] [Accepted: 03/29/2021] [Indexed: 12/18/2022] Open
Abstract
Background Patients with sickle cell disease (SCD) experience significant medical and psychological stressors that affect their mental health, well-being, and disease outcomes. Digital cognitive behavioral therapy (CBT) has been used in other patient populations and has demonstrated clinical benefits. Although evidence-based, nonpharmacological interventions for pain management are widely used in other populations, these treatments have not been well studied in SCD. Currently, there are no adequately powered large-scale clinical trials to evaluate the effectiveness and dissemination potential of behavioral pain management for adults with SCD. Furthermore, some important details regarding behavioral therapies in SCD remain unclear—in particular, what works best for whom and when. Objective Our primary goal is to compare the effectiveness of two smartphone–delivered programs for reducing SCD pain symptoms: digital CBT versus pain and SCD education (Education). Our secondary goal is to assess whether baseline depression symptoms moderate the effect of interventions on pain outcomes. We hypothesize that digital CBT will confer greater benefits on pain outcomes and depressive symptoms at 6 months and a greater reduction in health care use (eg, opioid prescriptions or refills or acute care visits) over 12 months. Methods The CaRISMA (Cognitive Behavioral Therapy and Real-time Pain Management Intervention for Sickle Cell via Mobile Applications) study is a multisite comparative effectiveness trial funded by the Patient-Centered Outcomes Research Institute. CaRISMA is conducted at six clinical academic sites, in partnership with four community-based organizations. CaRISMA will evaluate the effectiveness of two 12-week health coach–supported digital health programs with a total of 350 participants in two groups: CBT (n=175) and Education (n=175). Participants will complete a series of questionnaires at baseline and at 3, 6, and 12 months. The primary outcome will be the change in pain interference between the study arms. We will also evaluate changes in pain intensity, depressive symptoms, other patient-reported outcomes, and health care use as secondary outcomes. We have 80% power to detect a difference of 0.37 SDs between study arms on 6-month changes in the outcomes with 15% expected attrition at 6 months. An exploratory analysis will examine whether baseline depression symptoms moderate the effect of the intervention on pain interference. Results This study will be conducted from March 2021 through February 2022, with results expected to be available in February 2023. Conclusions Patients with SCD experience significant disease burden, psychosocial stress, and impairment of their quality of life. CaRISMA proposes to leverage digital technology and overcome barriers to the routine use of behavioral treatments for pain and depressive symptoms in the treatment of adults with SCD. The study will provide data on the comparative effectiveness of digital CBT and Education approaches and evaluate the potential for implementing evidence-based behavioral interventions to manage SCD pain.

Abstract
Vaso-occlusive pain crises are the hallmark of sickle cell disease (SCD) and the primary reason for health care utilization. Both national and international guidelines recommend aggressive intravenous opioids, intravenous fluids and anti-inflammatory therapy as the mainstay of treatment for acute SCD pain. However, many vaso-occlusive crises are managed at home with oral medication and supportive care. There are no guidelines on home medication management of SCD-related pain, likely due to the lack of well-defined endpoints for acute events and the lack of funding for already approved pain medications. Amplifying this issue is the growing concern for opioid abuse and misuse in the United States (US) and internationally. This study aimed to evaluate differences in opioid prescribing practices among providers treating SCD in the US and internationally. A survey was disseminated electronically to known providers using a combination of purposive and snowball sampling strategy. There were 127 responses and 17 countries represented. US providers were more likely to prescribe opioids (p < 0.001) and were more likely to be “very comfortable” prescribing opioids than non-US prescribers (p < 0.001). US providers also tended to prescribe more tablets per patient of stronger opioids than non-US physicians. US physicians were more likely to be concerned that patients were abusing opioids than non-US physicians (32% vs. 27%, p < 0.05). There are significant variations in how different parts of the world manage pain in the outpatient setting for SCD. Identifying optimal home pain management strategies is necessary to improve care and long-term outcomes in SCD.

Abstract
Importance The hallmark of sickle cell disease (SCD) is vaso-occlusive pain that may be acute and episodic or may progress to chronic, persistent pain with unpredictable and disabling exacerbations. Patients with SCD rely on opioids almost exclusively for acute and chronic pain management. Objective To understand how the current opioid epidemic and subsequent guidelines from the Centers for Disease Control and Prevention are associated with the management of acute and chronic pain for patients with SCD. Design, Setting, and Participants Qualitative study using semistructured interview guides. Interviews 1 hour or longer were conducted over the telephone. Participants were adults (aged ≥18 years) diagnosed with SCD who experienced pain on 3 or more days per week recruited from national SCD conferences, symposiums, and 2 sickle cell clinics. Open coding analysis facilitated thematic analysis of interview transcripts. Data collection took place from May 2017 to June 2018. Main Outcomes and Measures Participant perspective of any changes to their pain management associated with the 2016 guidelines from the Centers for Disease Control and Prevention. Results The 15 adults interviewed had a median (range) age of 32 (21-52) years; 13 (87%) were female; and all were of African American race/ethnicity. Participants reported that recently their opioid prescriptions had become more restrictive, were more closely monitored, and were increasingly difficult to fill in pharmacies. Participants also described increased stigmatization about opioid use and that their medical care was being affected by the physician's exclusive focus on reducing pain medication use. There was an emerging interest among adult patients in the consideration of the use of alternative therapies, including marijuana, to manage pain. Conclusions and Relevance These findings suggest that from the perspective of adults living with SCD, the opioid epidemic may have negatively affected patients' care by increasing barriers to opioids. Patients reported decreased opioid dosing, increased stigmatization regarding opioid use, physician preoccupation with opioid dosage interfering with comprehensive care, and lack of access to alternative therapies.
