AI Article Synopsis
- The study aimed to assess how well combining HPLC and IEF can predict rare hemoglobin variants.
- In a group of 40 patients, this combination correctly diagnosed 97.5% of cases (39 out of 40) versus a much lower accuracy when using each method alone.
- A new PCR test was also developed for a specific hemoglobin variant, showing it can be a quick, simple, and cost-effective diagnostic tool.
Article Abstract
Objective: To investigate the predictive accuracy of using a combination of the high pressure liquid chromatography (HPLC) retention time and the relative isoelectric focusing (IEF) position to diagnose rare hemoglobin variants.
Methods: A selected group of 40 patients with a rare beta-chain variant were assigned a presumed diagnosis following HPLC and IEF screening and then the variant identified in each case by DNA analysis. The study was conducted at the National Hemoglobinopathy Reference Laboratory, Oxford, United Kingdom, from August 2008 to October 2008.
Results: Thirteen out of 14 different variants were predicted accurately in 39 (97.5%) cases, compared to only one each for HPLC and IEF when used individually. A novel amplification refractory mutation system-polymerase chain reaction test was developed for Hb J-Baltimore and used successfully, to provide a simple, rapid, and inexpensive diagnosis.
Conclusion: The use of both HPLC retention time and isoelectric focusing position provides an accurate presumed diagnosis of a rare hemoglobin variant in the majority of cases. Amplification refractory mutation system-polymerase chain reaction test can provide a simple, rapid and inexpensive molecular diagnostic method for rare beta-chain variants.

Introduction: Extramedullary hematopoiesis (EMH) is very rarely described during sickle cell disease (SCD). Our aim was to describe six cases of EMH occurring in adult SCD patients and to conduct a literature review.
Methods: Retrospective, descriptive, and monocentric study, identifying all cases of EMH recorded in our cohort of adult SCD patients, up to April 2024.
