Results of a study on bone marrow (BM) cytology and cellularity, BM granulocytic-macrophage colony formation (GM-CFU-C), peripheral blood (PB) colony stimulating factor (CSF) and serum lysozyme activity in 20 elderly people aged from 64 to 89 are presented. Besides slight iron deficiency anemia, no hematological abnormality was detected. No change in PB and BM differential counts was found as compared to those obtained for normal adults. The BM cellularity and colony incidence were assessed using aliquots of the same specimen. GM-CFU-C frequency ranged from 15 to 156 (average 67.5) per 2 X 10(5) BM cells seeded. The largest number of colonies was observed in hypocellular BM samples (p less than 0.002). The level of serum lysozyme activity for the entire group was significantly higher than that obtained in healthy persons up to the age of 60 (p less than 0.001). The overall results support the notion that in old age, increased proliferation of committed granulopoietic stem cells in hypoplastic areas of the BM, assure normal numbers of mature blood cells in the periphery.

Haematological abnormalities are frequently encountered in patients with systemic lupus erythematosus (SLE). Anaemia is the most common hematological abnormality in SLE, it is multifactorial. The most common form of anaemia is that of chronic disease, and it is relate with inflammatory cytokines. Other tips of anaemia are: iron deficiency anaemia, autoimmune haemolytic anaemia, pure red cell aplasia. Leucopenia is related to neutropenia and/or lymphopenia. Thrombocytopenia is common, autoimmune and associated with a decreased survival. The presence of antiphospholipid antibodies increase risk of thrombosis in patients with SLE.

An important indication for bone marrow investigation is the presence of bone marrow failure, which manifests itself as (pan)cytopenia. The causes of cytopenia are varied and differ considerably between childhood and adulthood. In the paediatric age group inherited bone marrow failure syndromes are important causes of bone marrow failure, but they play only a minor role in later life. This review gives a comprehensive overview of bone marrow failure disorders in children and adults. We classified the causes of bone marrow failure according to the main presenting haematological abnormality, i.e. anaemia, neutropenia, thrombocytopenia or pancytopenia. The following red cell disorders are discussed: red cell aplasia, sideroblastic anaemia, congenital dyserythropoietic anaemia, haemolytic anaemia, paroxysmal nocturnal haemoglobinuria, iron deficiency anaemia, anaemia of chronic disease and megaloblastic anaemia. The neutropenias occur in the context of Shwachman-Diamond syndrome (SDS), severe congenital neutropenia, cyclic neutropenia, immune-related neutropenia and non-immune neutropenia. In addition, the following causes of thrombocytopenia are discussed: congenital amegakaryocytic thrombocytopenia, thrombocytopenia with absent radii, immune-related thrombocytopenia and non-immune thrombocytopenia. Finally, we pay attention to the following pancytopenic disorders: Fanconi anaemia, dyskeratosis congenita, aplastic anaemia, myelodysplastic syndromes and human immunodeficiency virus (HIV) infection.
