D57.02

Clinical Causes: Inherited genetic mutation affecting hemoglobin production (hemoglobin S). Presence of two sickle cell genes inherited from parents, causing the sickling of red blood cells. Triggering factors such as infections, dehydration, or stress that can precipitate splenic sequestration episodes.

Key Symptoms: Sudden and rapid enlargement of the spleen (splenomegaly). Severe abdominal pain and tenderness in the upper left abdomen. Low blood pressure and signs of shock. Weakness, pallor, or fatigue due to anemia. Fever or signs of underlying infection. Rapid heart rate and breathing difficulties. Lethargy or irritability, especially in children.

Diagnosis Path: Diagnosis is established through a combination of clinical evaluation and laboratory tests. Key steps include: - Medical history and physical examination, focusing on spleen size and anemia-related symptoms. - Blood tests such as a complete blood count (CBC) to assess anemia severity. - Hemoglobin electrophoresis to confirm the presence of hemoglobin S. - Imaging studies like ultrasound to evaluate spleen size and detect sequestration episodes. Prompt diagnosis is vital for early intervention and management to prevent serious complications.

Treatment Protocols: Management of Hb-SS disease with splenic sequestration involves urgent medical care during episodes and ongoing preventive strategies: - Emergency treatment often includes blood transfusions to restore normal hemoglobin levels and improve circulation. - Hospitalization may be necessary for close monitoring and supportive care. - Pain management to alleviate discomfort. - Antibiotics to treat or prevent infections that can trigger episodes. - Consideration of splenectomy (surgical removal of the spleen) in recurrent or severe cases. - Long-term management with hydroxyurea or other medications to reduce sickling episodes. - Regular follow-up and comprehensive care to monitor overall health and prevent complications.
