The sickle cell gene in India represents a separate occurrence of the HbS mutation (the Asian haplotype), which has occurred against a genetic background characterised by high levels of fetal haemoglobin and widely varying frequencies of alpha thalassaemia. These features, which tend to inhibit sickling, change the expression of the disease, which, in India, may be further modified by poor nutrition, malaria and other infections, and limited public health resources. Sickle cell disease in Jamaica is predominantly of African origin (the Benin haplotype) and faces some similar challenges. This review assesses similarities and differences between disease expression in the two countries and seeks to explore lessons from Jamaica, which may be relevant to Indian health care. In particular, it addresses common causes of hospital admission as detailed from Indian clinical experience: anemia, bone pain crisis, and infections.

Sickle cell anemia (SCA) is a monogenic blood disease with complex and multifactorial pathophysiology. The endocannabinoid system (ECS) could be a candidate for modulating SCA complications, such as priapism, as it has demonstrated an essential role in hematopoiesis, platelet aggregation, and immune responses. We evaluated the association of ECS-related single nucleotide polymorphisms (SNP) (FAAH rs324420, MAGL rs604300, CNR1 rs7766029, and CNR2 rs35761398) with priapism in a Brazilian SCA cohort.

This quality improvement initiative aimed to reduce the no-show rate at a hospital-based tertiary sickle cell ophthalmology clinic. Missed appointments place a significant burden on the healthcare system, resulting in prolonged waiting times and underutilized clinical resources that impact the quality of care provided. Individuals with sickle cell disease commonly require multiple appointments to address the myriads of comorbidities associated with their disease.

Spontaneous epidural hematoma (EDH) is a rare sickle cell disease (SCD) complication. We report 3 pediatric cases with SCD and spontaneous EDH and 1 with subgaleal hematomas in the setting of vaso-occlusive crises and elaborate on their presentation and management. Through a scoping review, we identified 71 additional cases reported from 1970 to 2024 and highlighted notable features.

Autoimmune hemolytic anemia (AIHA) is a multifactorial disease that causes immune-mediated red blood cell destruction, resulting in anemia and hemolysis symptoms. Despite a significant understanding of its pathogenesis, the precise causes of AIHA remain largely unclear and are thought to be multifactorial. In this paper, we presented a case of sickle cell anemia who developed severe AIHA that failed to maintain response to multiple treatment lines, including steroids, intravenous immunoglobulin, rituximab, and immune suppressive medications.

Background: Sickle cell disease (SCD) and β-thalassemia patients with elevated gamma globin (HBG1/G2) levels exhibit mild or no symptoms. To recapitulate this natural phenomenon, the most coveted gene therapy approach is to edit the regulatory sequences of HBG1/G2 to reactivate them. By editing more than one regulatory sequence in the HBG promoter, the production of fetal hemoglobin (HbF) can be significantly increased.
