Insights
Sickle cell disease (SCD) diagnosis is improving, but symptom severity factors remain unclear. Red blood cell lysis resistance shows promise as an additional diagnostic tool for SCD patients with sickle cell hemoglobin (HbS).
Area of Science:
- Hematology
- Medical Diagnostics
- Genetics
Background:
- Sickle cell disease (SCD) is a genetic blood disorder with complex pathophysiology.
- Current diagnostic methods for sickle cell hemoglobin (HbS) are efficient but do not fully explain symptom variability.
- Understanding factors influencing SCD severity is crucial for patient management.
Purpose of the Study:
- To review the current knowledge on SCD pathophysiology, clinical complications, and diagnostic techniques.
- To highlight red blood cell lysis resistance as a potential additional diagnostic tool in SCD.
- To identify areas needing further research in SCD diagnostics and pathophysiology.
Main Methods:
- Literature review of existing studies on sickle cell disease.
- Analysis of current diagnostic approaches for sickle cell hemoglobin (HbS) status.
- Evaluation of red blood cell lysis resistance as a diagnostic marker.
Main Results:
- Fast and economical laboratory methods exist for determining sickle cell hemoglobin (HbS) status.
- The pathophysiology of SCD is well-studied, but factors influencing symptom severity and some lab findings require further investigation.
- Red blood cell lysis resistance is proposed as a valuable additional diagnostic tool.
Conclusions:
- While SCD diagnostics have advanced, further research is needed on factors affecting disease severity.
- Red blood cell lysis resistance warrants further investigation as a diagnostic aid for patients with sickle cell hemoglobin (HbS).
- Continued research is essential to fully understand and manage SCD complications.
Abstract:
We review the current knowledge of the pathophysiology of sickle cell disease (SCD), the clinical complications and the state of the art in SCD diagnostics. Today, a flexible laboratory concept allows the fast and economic clarification of the patients' sickle cell hemoglobin (HbS) status, e.g. additional compound heterozygosities. In contrast to a well-investigated pathophysiology of the disease, factors influencing the severity of symptoms as well as some laboratory findings in SCD still lack a final explanation. In this review, we focus on red cell lysis resistance as an additional diagnostic tool in SCD. There is a need for further studies regarding lysis resistance in blood samples from patients with HbS.
