Congenital dyserythropoietic anemia (CDA) is a rare disorder, which manifests clinically with varying degrees of anemia and hepatosplenomegaly. These features are not pathognomic and a diagnosis of CDA is generally considered after other causes of chronic hemolytic anemia have been ruled out. The clinico-hematological profile of 10 patients with CDA is presented in this communication. Six patients had CDA type II and four had CDA type I. 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.

A case of congenital malaria infection has been studied in a 46-day old female Korean infant. Her mother suffered from malaria infection during pregnancy in Uppervolta, Africa, and returned to Korea at the 9th month of gestation for delivery. At 39 days of age, the clinical features characterized by fever, irritability, pallor, jaundice and hepatosplenomegaly were developed. The laboratory data revealed a hemolytic anemia with thrombocytopenia, hyperbilirubinemia and increased hepatic enzyme values. A peripheral blood smear demonstrated intraerythrocytic malarial parasites snd gametocytes of Plasmodium falcifarum. She was successfully treated with quinine sulfate (25 mg/kg/day in three doses for 5 days) and trimethoprim/sulfamethoxazole (8 mg/kg/day in two doses for 5 days) orally, and repeated blood smear had been negative for malaria. This report also signifies the frst description of congenital malaria in Korea imported from Uppervolta in Africa. A brief review of related literature was made.

Ataxia-telangiectasia (AT) is an autosomal recessive syndrome of combined immunodeficiency. Hallmarks of the disease comprise progressive cerebellar ataxia, oculocutaneous telangiectasia, cancer susceptibility and variable humoral and cellular immunodeficiency. We describe a patient with AT presenting with autoimmune haemolytic anaemia, neutropenia, hepatosplenomegaly, lymphadenopathy and hyper-IgM at the age of 6 months. At the age of 26 months she developed persistent fever, progressive lymphadenopathy and pulmonary nodular infiltrates, which were responsive to steroid therapy.

Hemoglobin Hammersmith, a rare, unstable hemoglobin variant, was diagnosed in a 9-year-old Japanese girl. She presented with the typical manifestations of this disorder, including neonatal hyperbilirubinemia, followed by progressive hepatosplenomegaly, jaundice, and bilirubinuria. Because of severe hemolytic anemia, she received transfusions of red blood cells every 3 to 4 weeks. However, she underwent splenectomy at the age of 4 years and has continued to be in partial remission without requiring further transfusions. DNA sequence analysis of the polymerase chain reaction-amplified beta-globin gene revealed a point mutation (T --> C) in the second nucleotide of the 42nd codon of the beta-globin chain (beta 42(CD1) Phe --> Ser).

Leukoerythroblastosis is a rarely observed disease characterized by the presence of leukocytosis, erythroid and myeloid blast cells in peripheral blood. To our knowledge, it had not been diagnosed in a premature newborn before the case we report have.A female baby weighing 1164 grams, who was born prematurely at the 29th week of gestation by Cesarean section was referred to our newborn intensive care unit due to prematurity and respiratory distress with no prenatal pathological findings. Physical examination revealed tachypnea and hepatosplenomegaly. Routine laboratory measurements showed significant leukocytosis (85,000/mm3) and anemia (Hb: 9.6 g/dL and Hct: 27.6%). The platelet count was normal. The peripheral blood smear suggested leukoerythroblastosis with the presence of nucleated erythrocytes, monocytosis, and 4% blasts. Bone marrow cytogenetic examination was normal. Parvovirus B19 Ig G and M serology were detected to be positive. The etiological factors observed in leukoerythroblastosis occurring during neonatal and early childhood period are congenital-postnatal viral infections, juvenile myelomonocytic leukemia and osteopetrosis. To our knowledge, no case of leukoerythroblastosis in such an early phase has been reported in the in literature. As a result, premature delivery and leukoerythroblastosis were thought to have developed secondary to intrauterine parvovirus B19 infection. Leukoerythroblastosis is a rarely observed disease characterized by the presence of leukocytosis, erythroid and myeloid blast cells in peripheral blood. It is reported that it can be observed following hematologic malignancies especially juvenile myelomonocytic leukemia, acute infections, hemolytic anemia, osteopetrosis, myelofibrosis, neuroblastoma and taking certain medicines. To our knowledge, it has not been diagnosed in a premature newborn before. Here we the case of a newborn who was referred to our intensive care unit due to being born prematurely at the 29th week of gestation and diagnosed with leukoerythroblastosis.

Congenital erythropoietic porphyria (CEP) is a recessive autosomal disorder characterized by a deficiency in uroporphyrinogen III synthase (UROS), the fourth enzyme of the heme biosynthetic pathway. The severity of the disease, the lack of specific treatment except for allogeneic bone marrow transplantation, and the knowledge of the molecular lesions are strong arguments for gene therapy. An animal model of CEP has been designed to evaluate the feasibility of retroviral gene transfer in hematopoietic stem cells. We have previously demonstrated that the knockout of the Uros gene is lethal in mice (Uros(del) model). This work describes the achievement of a knock-in model, which reproduces a mutation of the UROS gene responsible for a severe UROS deficiency in humans (P248Q missense mutant). Homozygous mice display erythrodontia, moderate photosensitivity, hepatosplenomegaly, and hemolytic anemia. Uroporphyrin (99% type I isomer) accumulates in urine. Total porphyrins are increased in erythrocytes and feces, while Uros enzymatic activity is below 1% of the normal level in the different tissues analyzed. These pathological findings closely mimic the CEP disease in humans and demonstrate that the Uros(mut248) mouse represents a suitable model of the human disease for pathophysiological, pharmaceutical, and therapeutic purposes.

Patients with systemic lupus erythematosus (SLE) have an extremely variable prognosis and mortality. The purpose of this report is to highlight the importance of looking for lupus parameters in patients with autoimmune haemolytic anaemia (AIHA) and/or immune thrombocytopenia (ITP) as this represents a subgroup of systemic lupus erythematosus (SLE) patients with a fairly good prognosis. We report a case of an 8-year-old Malay boy who was admitted to hospital with fever and gum bleeding. Physical examination revealed a malar rash, oral ulcers, petechial haemorrhages and bruises over the limbs, generalised lymphadenopathy and hepatosplenomegaly. Laboratory investigations confirmed the diagnosis of SLE. The patient's serum showing the presence of antinuclear factor, antiphospholipid antibodies and a biological false-positive test for syphilis. Immunological and haematological parameters were in keeping with combined AIHA and ITP (Evans' syndrome). No organ involvement was present and the patient responded well to corticosteroid therapy. This case demonstrates the importance of making an early diagnosis of SLE with haematological complications, in order to ensure full benefit of therapy and emphasises the good prognosis expected in this subgroup of SLE patients.

Hb Southampton (also known as Hb Casper) is characterized by the substitution of a leucine residue for a proline at codon beta106 (CTG-->CCG). This mutation breaks the G helix and severely distorts the tertiary structure of the molecule, producing an unstable hemoglobin (Hb) and severe hemolysis. We identified this hemoglobinopathy in a young patient with severe hemolytic anemia and hepatosplenomegaly.

Transaldolase (TALDO) deficiency is a newly recognized metabolic disease, which has been reported so far in 2 patients presenting with liver failure and cirrhosis. We report a new sibship of 4 infants born to the same consanguineous parents; all presented at birth or in the antenatal period with dysmorphic features, cutis laxa and hypertrichosis, hepatomegaly, splenomegaly, liver failure, hemolytic anemia, thrombocytopenia, and genitourinary malformations. The clinical courses were variable: the first child died of liver failure at 4 months of age; the second pregnancy was medically terminated at 28 weeks gestation because of hydrops fetalis with oligohydramnios. The third child is doing well at age 7 with liver fibrosis and mild kidney failure. The fourth child is now 21 months old and has hepatosplenomegaly, mild anemia, and thrombocytopenia. Urine assessment of polyols showed elevations of erythritol, arabitol, and ribitol consistent with TALDO deficiency. TALDO activity was undetectable in the patients' tissues, and mutation in the TALDO1 gene was found in the 4 patients.

Amiodarone therapy is associated with several adverse effects, including hematologic ones such as pancytopenia, hemolytic anemia, and aplastic anemia. Very few cases of amiodarone-associated bone marrow granulomas have been reported. We report 2 cases of amiodarone-associated bone marrow granulomas. Patient 1 was an 81-year-old man who presented with leukopenia, thrombocytopenia, and hepatosplenomegaly after 2 years of amiodarone therapy. Patient 2 was an 80-year-old man who presented with pancytopenia 2 1/2 years after starting amiodarone treatment. Both patients had normal blood counts before amiodarone therapy. Bone marrow biopsies showed noncaseating granulomas in both patients. We reviewed the literature available on Medline for amiodarone-associated bone marrow granulomas and found 8 reported cases of amiodarone-associated bone marrow granulomas. One case also featured amiodarone-associated hepatic granulomas. Amiodarone therapy was stopped in 5 cases, with improvement of the granulomas occurring in 3 cases. We conclude that bone marrow granulomas, although rare, should be considered as a differential diagnosis for patients undergoing amiodarone therapy and presenting with cytopenias.
