Sickle cell anaemia is an inherited blood disorder affecting the production of red blood cells, causing them to be sickle-shaped and unable to carry oxygen properly. The spelling of this word is based on the International Phonetic Alphabet (IPA) transcription, which is represented as /ˈsɪkəl sɛl əˈniːmiə/. The initial sound /s/ is followed by a short /i/ as in "sit", then /k/ and /l/ consonants followed by a short /e/ sound as in "bet". Finally, the word ends with a long /i:/ as in "me". Sickle cell anaemia affects millions of people worldwide, particularly in Africa and regions with high prevalence of malaria.
Sickle cell anaemia is a genetic blood disorder that primarily affects individuals of African, Middle Eastern, Indian, Mediterranean, and Latin American descent. It is a form of sickle cell disease characterized by the presence of abnormal crescent-shaped red blood cells (RBCs).
In normal circumstances, RBCs are round and flexible, allowing them to easily travel through blood vessels to transport oxygen to different parts of the body. However, in individuals with sickle cell anaemia, the red blood cells become rigid and assume a sickle shape. These abnormal cells can easily get trapped, causing blockages and reducing the overall oxygen supply to various organs and tissues.
The symptoms of sickle cell anaemia can range from mild to severe and usually manifest within the first year of life. Common symptoms include chronic fatigue, shortness of breath, frequent infections, delayed growth, and episodes of severe pain referred to as "sickle cell crisis." This disorder is caused by mutations in the gene responsible for producing hemoglobin, the protein that enables RBCs to carry oxygen.
While there is currently no cure for sickle cell anaemia, treatments focus on managing symptoms and preventing complications. This may involve blood transfusions, pain medications, and antibiotics to manage infections. Additionally, patients are encouraged to adopt a healthy lifestyle, including proper hydration, regular exercise, and avoidance of factors that may trigger a sickle cell crisis, such as extreme temperature changes or dehydration.
Sickle cell anaemia can significantly impact an individual's quality of life and requires ongoing medical care and support. Genetic counseling is crucial for affected individuals and their families to understand the inheritance pattern of the disorder and make informed decisions regarding family planning.
