Congenital dyserythropoietic anemia type I (CDA1) can present in utero with hydrops fetalis, but more often it presents in childhood or adulthood with moderate macrocytic anemia, jaundice, and progressive iron-overload. [ncbi.nlm.nih.gov]

Patients often present with anemia, jaundice, and variable splenomegaly. Most cases of CDA II are diagnosed at a young age; some patients, however, may remain unrecognized until late adulthood. [scholars.northwestern.edu]

• Splenomegaly

  Congenital dyserythropoietic anemia type II (CDA II) is the most common form of CDA (see this term) characterized by anemia, jaundice and splenomegaly and often leading to liver iron overload and gallstones. [monarchinitiative.org]

  Patients often present with anemia, jaundice, and variable splenomegaly. Most cases of CDA II are diagnosed at a young age; some patients, however, may remain unrecognized until late adulthood. [scholars.northwestern.edu]

  CDA I patients have a moderate macrocytic anemia with frequent splenomegaly and occasional hepatomegaly. [orpha.net]

  Neonatal manifestations (anemia, early jaundice, and/or splenomegaly) and bone abnormalities were present in 11 of the 12 and 6 of the 12 patients, respectively. CDA I was initially misdiagnosed in four children. [ncbi.nlm.nih.gov]

• Splenectomy

  Splenectomy produced an increased hemoglobin (P <.001) and a reduced bilirubin level (P =.007) in comparison with values before splenectomy. Preliminary data indicate that iron overload occurs irrespective of the hemochromatosis genotype. [ncbi.nlm.nih.gov]

  Thirty percent of the patients had splenectomy when last observed. From our analysis, splenectomy is sometimes of benefit because anemia improves and hemolysis decreases. [doi.org]

  Splenectomy, performed in 22 cases, led to moderate increases in hemoglobin values and eliminated the need for transfusions but did not prevent further iron loading. [bloodjournal.hematologylibrary.org]

• Pallor

  Age at onset of pallor ranged from birth to 9 years. Blood transfusion requirements varied from nil to monthly. This is the first report of CDA type I from India. [ncbi.nlm.nih.gov]

  On the other hand chronic blood loss is characterized by pallor out of proportion to distress and possibly signs of congestive cardiac failure, including hepatomegaly. [oncologynurseadvisor.com]

  Symptoms & Diagnosis The most common symptoms of CDA include: Fatigue Lack of energy Jaundice Pale skin (pallor) Enlarged spleen or liver Formation of gallstones Skeletal abnormalities, including missing fingers and toes CDA is diagnosed with: Blood tests [danafarberbostonchildrens.org]

  Physical signs include pallor, signs of a hyperkinetic circulation (tachycardia, wide pulse pressure with capillary pulsation, cardiac murmurs), signs of congestive cardiac failure, and hemorrhages and exudates in the retina. [clinicalgate.com]

• Family History of Anemia

  We present a patient with CDA type 1 who had severe anemia develop during the fetal period resulting in cardiac failure and death. CASE REPORT The patient was born to nonconsanguineous, healthy parents without a family history of anemia. [journals.lww.com]

• Tachycardia

  Symptoms of anemia include fatigue, failure to thrive in infants, headache, dizziness, leg cramps, tachycardia and insomnia. Erythropoiesis is always dysfunctional, as revealed by cellular anomalies and erythroid hyperplasia. [orpha.net]

  Symptoms for both types include: Chest pain Fast heartbeat, or tachycardia Headaches Trouble breathing Weakness and fatigue Treatment for sideroblastic anemia depends on the cause. [webmd.com]

  Acute blood loss at the time of delivery may be characterized by minimal pallor that worsens over the first 24 hours, with rapid, shallow or gasping respiration, tachycardia, and shock with low blood pressure. [oncologynurseadvisor.com]

• Hepatosplenomegaly

  Most affected individuals do not have hepatosplenomegaly, and iron does not build up in tissues and organs. In adulthood, abnormalities of a specialized tissue at the back of the eye (the retina) can cause vision impairment. [ncbi.nlm.nih.gov]

  The resulting shortage of healthy red blood cells leads to the characteristic signs and symptoms of anemia, as well as complications including hepatosplenomegaly and an abnormal buildup of iron. [ghr.nlm.nih.gov]

• Osteoporosis

  Main complications were due to anemia and ineffective erythropoiesis [osteoporosis (8/9, 89%), cholelithiasis (21/30, 70%), pulmonary arterial hypertension (PAH) (6/25, 24%)] and iron overload [hypothyroidism (9/24, 38%), and diabetes mellitus (6/32, [ncbi.nlm.nih.gov]

In 2 exceptional cases, long-standing moderate anemia was investigated in the workup of an unrelated disorder, and the correct diagnosis was recognized at 62 and 78 years, respectively. [doi.org]

• Macrocytic Anemia

  This report describes a case of congenital dyserythropoietic anemia (CDA) type I diagnosed in a 22-year-old woman with a two year history of macrocytic anemia. [ncbi.nlm.nih.gov]

  Three types are described: type I [MIM224120], macrocytic, megaloblastic anemia with erythroblastic internuclear chromatin bridges; type II, [MIM*224100], normoblastic anemia with multinucleated erythroblasts; type III, macrocytic anemia with erythroblastic [medical-dictionary.thefreedictionary.com]

• Macrocytosis

  Herein is described the case of a young woman presenting with iron overload and macrocytosis. The initial diagnosis was hereditary hemochromatosis. [ncbi.nlm.nih.gov]

  The disorder is characterized by mild anemia, macrocytosis in the peripheral blood, and giant multinucleated erythroblasts (containing up to 12 nuclei) in the bone marrow. [rarediseases.info.nih.gov]

  Ineffective erythropoiesis results in an anemia of variable severity associated with a mild macrocytosis, a normal, or at most slightly elevated, absolute reticulocyte count, a moderate increase in unglycosylated (indirect) bilirubin, a low haptoglobin [accessmedicine.mhmedical.com]

• Hemoglobin Decreased

  Cord blood hemoglobin (Hb) at birth in full term infants is 16-17g/dL, does not decrease appreciably during the first week of life, and then declines slowly to a physiological nadir of 11g/dL by 8-12 weeks. [oncologynurseadvisor.com]

• Reticulocytes Increased

  On this treatment, hemoglobin and reticulocytes increased and transfusions became unnecessary. In keeping with a few previous reports, interferon alpha2b proved to be effective in congenital dyserythropoietic anemia, type 1. [ncbi.nlm.nih.gov]

Response to the treatment was monitored using the blood count and reticulocyte count. The patient was age 14 when interferon treatment was started. [ncbi.nlm.nih.gov]
