Presentation
We present two cases of congenital sideroblastic anemia with their clinico-hematological profile. Case 1 A 1.5 year-old-male child presented in the outpatient department of hematology with complaints of pallor since birth. [ijpmonline.org]
/INSERT} {INSERT-2-3} Stand out and be remembered with Prezi, the secret weapon of great presenters. Present to your audience Start remote presentation. An autosomal dominantly inherited form anemia sideroblastica exists but is extremely rare. [pdfoftheworld.us]
Patients can present at any age with symptoms of anemia or iron overload. 4, 11 Physical examination is unremarkable although mild hepatosplenomegaly may be present. [clinicalgate.com]
Patients of CSA presents with hereditary hypochromic anemia which is apparently not due to iron deficiency or thalassemia. The two infants in this report presented at an early age with pallor and hepatospleno-megaly. [indianpediatrics.net]
This is also appreciated by an elevated RDW (this is a measure of the variation in red cell diameter and size, the result is presented on the CBC slip) value on the complete blood count (CBC). [psychiatryadvisor.com]
Entire Body System
- Fatigue
Moderate to severe anemia with fatigue, dizziness, and dyspnea should prompt an evaluation for SA. Symptoms of anemia, including fatigue, dizziness, and dyspnea ( 3 )[ A ] Alcohol or drug ... Treatment is largely supportive ( 2 )[ A ]. [5minuteconsult.com]
Iron builds up in red blood cells, and patients may have a hard time breathing and feel weak and fatigued. All types of blood cells are low. [cincinnatichildrens.org]
The signs and symptoms of this condition may include fatigue, breathing difficulties, weakness, and enlargement of the liver or spleen. [rarediseases.info.nih.gov]
This is due to the mutations in the erythroid-specific ALA synthase gene (ALAS). [3] Shortness of breath on exertion on exertion [7] malaise, fatigue These are symptoms of anemia, Anaemia cause low oxygenation of the blood, Hypoxia can be sensed by the [explainmedicine.com]
Weakness, fatigue and palpitations are due to cardiac involvement. Iron toxicity leads to defective hormone production which can lead to growth delay. [themedicalbiochemistrypage.org]
Cardiovascular
- Ejection Murmur
A systolic ejection murmur and hepatomegaly were present on physical examination. Laboratory values are shown in Table 1. [nature.com]
Eyes
- Abnormal Eye Movement
Mild speech difficulties (dysarthria), tremor, and abnormal eye movements have also been reported in some affected individuals. [ Read More ] X-linked sideroblastic anemia X-linked sideroblastic anemia is an inherited disorder that prevents developing [icdlist.com]
Face, Head & Neck
- Frontal Bossing
On examination, severe pallor and frontal bossing were noted. There was no icterus, cyanosis, clubbing or lymphadenopathy. Liver was palpable 4 cm below costal margin and spleen was not palpable. The milestones were normal for age. [ijpmonline.org]
Urogenital
- Kidney Failure
Heart disease, liver damage, and kidney failure can result from iron buildup in these organs. [slideshare.net]
Heart disease, liver damage, and kidney failure can result from iron buildup in these organs. [7] Causes [ edit ] Causes of sideroblastic anemia can be categorized into three groups: congenital sideroblastic anemia, acquired clonal sideroblastic anemia [en.wikipedia.org]
Neurologic
- Headache
You may be short of breath or have a headache. Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have. [icdlist.com]
Headache. Irritability and other mood disturbances. Mental confusion. Loss of sexual drive. Shortness of breath on exertion. [doctor-clinic.org]
The symptoms and signs of congenital sideroblastic anemia (CSA) in children are primarily related to the anemia and its severity: Fatigue, weakness Irritability Exercise/feeding intolerance Exertional dyspnea Headache, vertigo Pale or yellow skin Some [danafarberbostonchildrens.org]
Workup
Workup may include a complete blood count (CBC), peripheral smear, iron studies (eg, ferritin and total iron-binding capacity [TIBC]), bone marrow aspiration and biopsy, and other studies as appropriate. [emedicine.medscape.com]
Serum
- Lymphopenia
B cell lymphopenia, variable panhypogammoglobulinemia and/or low levels of mature CD19+ B cells in the blood. [autoinflammatory-search.org]
Biopsy
- Bone Marrow with Ringed Sideroblasts
The ICD code D640 is used to code Sideroblastic anemia Sideroblastic anemia or sideroachrestic anemia is a form of anemia in which the bone marrow produces ringed sideroblasts rather than healthy red blood cells (erythrocytes). [icd.codes]

Treatment
After all tests are completed, the hematologist will be able to outline the best treatment options. How is congenital sideroblastic anemia treated? Treatment for CSA depends on the exact type and severity of the disorder. [danafarberbostonchildrens.org]

Management and treatment Treatment is supportive and involves hematological monitoring, the surveillance of iron levels, lifetime pyridoxine supplementation in those who respond and folic acid supplementation. [orpha.net]
Treatment The underlying cause determines the course of treatment. Hereditary sideroblastic anemia usually responds to several weeks of treatment with high doses of pyridoxine. [doctor-clinic.org]
Molecular analysis of these cases will contribute not only to the development of effective treatment, but also to the understanding of mitochondrial iron metabolism. [ncbi.nlm.nih.gov]
Prognosis
A normal karyotype carries the most favorable prognosis. Monosomy 7 or deletions of the long arms of chromosome 7 are associated with a worse prognosis. “What if” scenarios. [psychiatryadvisor.com]
Prognosis Prognosis is variable but for patients with pyridoxine-responsive anemia whose iron stores are kept low, normal life expectancy should be achievable The documents contained in this web site are presented for information purposes only. [orpha.net]
Few patients are eligible for transplant. [ 1 ] Prognosis [ 9 ] The prognosis is very variable. Reversible causes (eg, alcohol or drugs) appear to have no long-term effects if the underlying cause is successfully treated or removed. [patient.info]
The prognosis of sideroblastic anemia is highly variable. Share anemia sideroblastica and questions with Physicians on Medscape consult. [pdfoftheworld.us]
Course and prognosis Sideroblastic anemia’s are often described as responsive or non-responsive in terms of increased Hb level to pharmacological doses of vitamin B6. 4. بالتوفيق لي ادعو Page 4 [slideshare.net]

Etiology SA is due to inherited or de novo mutations in the ALAS2 gene (Xp11.21) encoding the erythroid form of delta amino levulinic acid synthase (ALAS2), which altered function leads to impaired heme synthesis. [orpha.net]

Prophylactic occasional phlebotomy can be performed to prevent iron overload, if anemia is very mild or corrected by pyridoxine. [orpha.net]
ALAS2 mutations impair the activity of erythroid ALA-synthase, which disrupts normal heme production and prevents erythroblasts from making enough hemoglobin. [ghr.nlm.nih.gov]
