A 2020 guideline for acute and chronic pain management in patients with sickle cell disease (SCD) by the American Society of Hematology (ASH) suggests tailored opioid therapy, when indicated, for adults and children with SCD in the acute care setting (adults: conditional recommendation, moderate certainty; children: conditional recommendation, low certainty). The ASH also suggests a short course (5 to 7 days) of nonsteroidal anti-inflammatory drugs (NSAIDs) in addition to opioids for acute pain (conditional recommendation, low certainty), and regional anesthesia for localized pain (conditional recommendation, low certainty). For acute pain related to SCD in hospitalized adult and pediatric patients, adjunctive subanesthetic ketamine infusion is suggested with refractory pain or after opioid monotherapy is deemed ineffective (conditional recommendation, low certainty). However, due to an absence of data, ASH guidelines were unable to derive recommendations for buprenorphine use for patients with pain associated with SCD. The panel followed with research priorities, which included a need for comparative-effectiveness studies between full agonist opioids and partial agonist opioid therapy, such as buprenorphine. [1]
A 2020 review explored the multifaceted aspects of chronic pain management in patients with SCD, particularly focusing on the challenges of distinguishing pain types and treatment limitations. Chronic pain in SCD often coexists with mental health disorders, including depression and anxiety, further complicating treatment. The inadequacy of chronic opioid therapy (COT) as an optimal treatment strategy for SCD-related chronic pain is noted, due to its association with opioid-induced hyperalgesia, opioid toxicity, and opioid withdrawal symptoms, which are often misdiagnosed as vaso-occlusive crisis (VOC) symptoms, leading to frequent acute care utilization. The review analyzed two real-world case studies where treatment regimens focused on identifying non-SCD-related contributors to pain and addressing opioid dependency issues through the careful use of sublingual buprenorphine/naloxone and optimizing SCD-modifying therapies, such as hydroxyurea or L-glutamine. In one case where a 25-year-old African American woman with SCD and diagnosis of physiologic opioid dependence and cyclic opioid withdrawal was transitioned from as-needed oxycodone and frequent intravenous (IV) opioids to sublingual buprenorphine/naloxone, the patient’s acute care use significantly decreased, hydroxyurea adherence improved, Hb F rose from 8% to 42% over 12 months, and no ED visits during this 12-month period. Despite a lack of strong evidence supporting buprenorphine products for chronic pain in SCD, buprenorphine/naloxone may be worth considering for patients with SCD on COT who have a high opioid risk score, are experiencing cyclic opioid withdrawal, or meet criteria for physiologic opioid dependence.
