Skin ulcers complicating sickle cell disease: an interlinked reparative model

Area of Science:

• Hematology
• Dermatology
• Vascular Medicine

Background:

• Skin ulcers are a frequent and debilitating complication of sickle cell disease (SCD), predominantly affecting the lower extremities, especially in homozygous forms.
• These ulcers result from multifactorial pathogenetic mechanisms, including chronic microvascular disturbances and capillary stasis in areas with limited subcutaneous fat, leading to significant impacts on patient quality of life.

Observation:

• The case involves a young woman with severe skin complications secondary to sickle cell disease (drepanocytosis).
• Her ulcers were chronic, unhealable, and had a significant impact on her pain and psycho-physical well-being, despite previous care attempts.

Findings:

• Higher fetal hemoglobin (HbF) concentrations may offer protection against sickle hemoglobin (HbS) polymerization, potentially influencing ulcer healing.
• Clinical features of the ulcer were key predictors for determining the optimal treatment strategy.
• An integrated treatment model combining surgery, advanced medications, and adequate transfusional support, particularly in the early stages, led to successful clinical outcomes.

Implications:

• This case highlights the potential of a multidisciplinary, interlinked reparative model for managing recalcitrant sickle cell-related skin ulcers.
• Early and adequate transfusional support, alongside surgical and pharmacological interventions, can be crucial for achieving healing in complex cases.
• Successful management of these ulcers can significantly improve the quality of life for patients suffering from hemoglobinopathies.
