Neutropenia is common in the practice of both primary care physicians and sub-speciality. Congenital neutropenia are rare diseases; they can be isolated independent diseases accompany a number other inborn errors immunity. The clinical course range from asymptomatic patients with mild to life-threatening infections cases severe neutropenia. Treatment congenital remains discutable this day. most...
The term congenital neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, severe (<0.5 G/l) or mild (between 0.5-1.5 G/l), which may also affect other organ systems such as the pancreas, central nervous system, heart, muscle and skin. Neutropenia can lead to life-threatening pyogenic infections, acute gingivostomatitis and chronic parodontal disease, and ea...
2007;39:86-92. 3. Person RE, Li FQ, Duan Z, et al. Mutations in proto-oncogene GFI1 cause human neutropenia and target ELA2. Nat Genet. 2003;34:308-312. 4. Donini M, Fontana S, Savoldi G, et al. G-CSF treatment of severe congenital neutropenia reverses neutropenia but does not correct the underlying functional deficiency of the neutrophil in defending against microorganisms. Blood. 2007;109:471...
Severe congenital neutropenia a clinically and genetically heterogeneous disorder. Mutations in different genes have been described as causative for severe neutropenia, e.g. ELANE, HAX1 and G6PC3. Although congenital neutropenia is considered to be a group of monogenic disorders, the phenotypic heterogeneity even within the yet defined genetic subtypes points to additional genetic and/or epigen...
Congenital neutropenia and cyclic neutropenia are disorders of neutrophil production predisposing patients to recurrent bacterial infections. Recently the locus for autosomal dominant cyclic neutropenia was mapped to chromosome 19p13.3, and this disease is now attributable to mutations of the gene encoding neutrophil elastase (the ELA2 gene). The authors hypothesized that congenital neutropenia...
BACKGROUND AND OBJECTIVES The two main complications of severe chronic neutropenia are fatal sepsis and myelodysplasia/acute leukemia (MDS/AL). Granulocyte colony-stimulating factor (G-CSF) therapy has significantly reduced the frequency and severity of infections, but its possible influence on the risk of malignancy is not known. DESIGN AND METHODS The French Severe Chronic Neutropenia (SCN)...
Several congenital disorders may cause neutropenia. The recent advances in the field of molecular biology have facilitated our knowledge concerning pathophysiological mechanisms leading to these disorders. The molecular basis of disorders with defective myelopoiesis (severe congenital neutropenia and cyclic neutropenia) and disorders due to defective RNA processing (Shwachman Diamond syndrome a...
