Objective: Chronic pain is a common symptom experienced among patients with sickle cell disease (SCD). Our aims were to assess the feasibility and acceptability of performing acupuncture for the treatment of chronic pain in adults with SCD. Methods: This was a single-arm, prospective pilot study of six adults with SCD. Participants reported ⩾ 3 months of chronic pain and were > 18 years of age. Per protocol, acupuncture was to be administered twice per week for 5 weeks, for 30 min per session. All treatments were performed in the acupuncture treatment laboratory at the University of Illinois Chicago College of Nursing. Pain intensity, pain interference, and other symptoms were measured at baseline and after the intervention. Participants completed a semi-structured interview and a protocol acceptability questionnaire after the acupuncture intervention. Results: Six participants (mean age 52.5 years, six Black) were enrolled. Although the study was suspended due to COVID-19 and not all participants completed the 10-session protocol, completion rates were high with no missed appointments. One participant did not complete the study due to hospitalization unrelated to acupuncture. No adverse events were reported. At completion of the intervention at 4–5 weeks post-baseline, all participants had reduced pain intensity and pain interference. The mean acceptability score on the protocol acceptability questionnaire was 82%. Conclusion: It was feasible and acceptable to implement acupuncture in adults with SCD. This study can be used to guide a larger randomized controlled trial to evaluate the effect of acupuncture on reducing chronic pain in adults with SCD.

Summary Haemolysis and vaso‐occlusion underlie multi‐organ system complications in sickle cell disease (SCD). We assessed real‐world biomarkers in University of Illinois adult SCD patients, categorised as severe (HbSS/Sβ0‐thalassaemia; n = 342) or mild (HbSC/Sβ+‐thalassaemia; n = 100) genotypes and stratified according to treatment. African‐American controls from the National Health and Nutrition Examination Survey (NHANES) were matched with each genotype category. Most measures of haemolysis, anaemia, inflammation and function of kidneys, liver and lungs differed markedly in untreated severe genotype patients compared to NHANES controls. These same biomarkers were significantly closer to the NHANES control range in untreated mild versus severe genotype patients, but they were not improved in severe genotype patients receiving treatment with hydroxycarbamide or blood transfusions, except that haemoglobin and HbF were higher with hydroxycarbamide. Systolic blood pressures did not differ among the SCD and NHANES groups, but diastolic pressures were higher in mild genotype patients. Ferritin in severe genotype patients on chronic transfusions was 50‐fold higher than NHANES controls. The cross‐sectional real‐world biomarkers of patients on hydroxycarbamide or transfusions were not markedly improved compared to untreated patients. This may be due partly to poor compliance or more severe disease. Our findings highlight the need for more effective treatments.
