Fanconi's anemia. Clinical study of six cases
Insights
This study presents six children with Fanconi's anemia, a rare blood disorder. Androgen therapy proved effective, improving outcomes for some patients with this genetic condition.
Area of Science:
- Hematology
- Genetics
- Pediatrics
Background:
- Presents six pediatric cases of constitutional aplastic anemia, specifically Fanconi's anemia.
- Focuses on the clinical and biological features of affected children.
Observation:
- All patients exhibited congenital abnormalities, including skin pigmentation, renal anomalies, and growth retardation.
- Common initial symptoms were anemia and thrombocytopenia; leukopenia was less frequent.
- Bone marrow analysis revealed hypocellularity, and chromosomal studies identified various abnormalities.
Findings:
- Five patients showed elevated fetal hemoglobin levels.
- Androgen therapy was administered to five cases, resulting in a positive response in all.
- Two patients remain alive and well, while four have died.
Implications:
- Highlights the significant role of androgen therapy in managing Fanconi's anemia.
- Emphasizes the observed androgen dependence in all treated cases.
- Correlates clinical and biological findings with existing literature on the condition.
Abstract:
Six cases of constitutional aplastic anemia (Fanconi's anemia), including four boys and two girls who were between 6 and 10 years of age, are presented. Congenital abnormalities were observed in all the patients, especially skin pigmentations, renal anomalies, and growth retardation. The initial symptoms were insidious, mainly related to the anemia. All patients were anemic and thrombocytopenic, but only three were leukopenic. Five cases showed increased levels of fetal hemoglobin, which was marked in two. Bone marrow obtained by aspiration and/or biopsy was hypocellular in all cases. Chromosomal studies showed breaks, ring- or cross-chromosomes, chromosome exchanges, and endoreduplications. Five cases were treated with androgens and a good response was obtained in all of them. Four patients died, and the remaining two are alive and well. The clinical and biological features of these patients are in accordance with those of previous reports. The importance of the androgen therapy is stressed; androgen dependence was observed in all cases.
