A novel sickle hemoglobin: hemoglobin S-south end.

J Pediatr Hematol Oncol

Hemoglobin Diagnostic Reference Laboratory, Boston Medical Center, Boston, Massachusetts, USA.

Published: November 2004

Sickle hemoglobin (Hb S; beta Glu6Val) is due to an AGTG; beta Lys132Asn, AAA>AAC). When present alone, the beta Lys132Asn mutation has low oxygen affinity. Therefore, this mutation may enhance the polymerization of the Hb S variant. Furthermore, the variant hemoglobin mimics Hb A on high-pressure liquid chromatography, and its identity is not easily diagnosed. A succinct review of variant sickle hemoglobins is also presented.

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.

Sickle cell disease (SCD) is of global significance due to its severity and occurrence worldwide. Inheritance of the abnormal hemoglobin structure contributes to microvascular events that underlie the development of the multi-systemic complications seen in the disease pathogenesis. Pulmonary complications are common and heterogeneous including pulmonary hypertension, sleep-disordered breathing and lung function abnormalities.

The knowledge of the prevalence and molecular basis of β-hemoglobinopathies constitutes an important prerequisite for an effective prevention program. To address this issue in Iraq's capital, Baghdad, a total of 12526 individuals (6263 couples) attending three main Premarital Screening centers were enrolled. Individuals were labeled as β-hemoglobin disorders based on full blood counts and high-performance liquid chromatography.

Clinical Features: Sickle cell patients may develop a multitude of antibodies and experience life-threatening events with transfusion such as hyperhemolysis syndrome or delayed hemolytic transfusion reaction. Further transfusion may not be possible in such cases.

Therapeutic Challenge: When conventional blood products are not available for transfusion yet the patient requires additional oxygen-carrying support, artificial oxygen carriers may be required.

Sickle cell disease (SCD) primarily affects people of African American descent in the United States. Many individuals do not know their sickle cell trait (SCT) status or might not be aware of SCD. The purpose of this study was to assess SCD knowledge, awareness of SCT status, and its impact on relationships.
