FEATURE “We definitely understand the need for limitation and proper use of opioids, but the more restrictions we put on patients who need opioids to treat their conditions at home, the more it has a downstream effect of increased suffering and reliance on the ED, when [patients] could have potentially treated their pain at home,” Dr. Brandow explained. “We can’t lose sight of the fact that patients living with these chronic conditions need pain treatment.” The lack of alternatives to opioids also highlights the necessity of the drugs. Ac- cording to Dr. Brandow, there is no body of evidence to support the use of other medications for sickle cell pain, though, in recent years, research has shed more light on the pain that people with SCD experience, with the ultimate goal of identifying “opioid- sparing” pain-management options. “In the past, people with SCD only lived into their teens or early 20s,” Dr. Clauw noted. “Now that they are living longer, it appears that the type of pain they experience is changing – from acute pain to a more centralized pain.” When sickle cell crises begin, opioids work well to manage the acute pain, he said. However, as with many chronic pain conditions, the type of pain – and the therapy needed to address it – changes over time. “In the beginning, pain was likely due to damage or inflammation in peripheral tissues, but as the disease continues, pain becomes driven by changes in the brain and central nervous system – a type of pain called central sensitization,” he explained. “This type of pain is coming more from the brain and spinal cord than the peripheral nervous system, and opioids don’t seem to work for that type of pain.” When people use opioids to treat long-term, chronic pain, they are likely to develop tolerance to the medications.
