The major role of immunophenotyping is in the diagnosis of the chronic lymphoproliferative disorders and of acute leukaemia which is not obviously myeloid.

The ML patients received granulocyte colony stimulating factor (G-CSF) in addition after chemotherapy. During the leucopenic phase only reticulocytes of low fluorescence ratio (LFR) at extremely low concentration (< 10 x 10(9)/l) were found. After a median interval of 17 days (range 8-43), the middle fluorescence fraction (MFR) began to rise, preceding high fluorescence ratio (HFR) reticulocytes by a median of 1 day in AL patients with complete or partial remission. In ML patients, MFR and HFR reticulocytes appeared more often simultaneously after a median interval of only 11 days (range 8-15) and increased faster during the first week of marrow recovery showing a pattern different from AL. Granulocytes passed the critical limit of 0.5 x 10(9)/l at a median of 5 days after appearance of MFR reticulocytes in AL but in ML on the same day as MFR and HFR (day 0). The absolute reticulocyte concentration reached the lower limit of the reference range after about 10 days in AL. Thus, finding MFR and, to a lesser extent, HFR at very low cell concentrations, may serve as sensitive early indicators of marrow recovery after chemotherapy and are much more sensitive parameters than the absolute reticulocyte concentration. The higher median values for reticulocytes (total, HFR and MFR) after G-CSF therapy suggests that G-CSF is not lineage specific and may also stimulate erythroid precursor cells.</p>","PeriodicalId":10285,"journal":{"name":"Clinical and laboratory haematology","volume":"18 Suppl 1 ","pages":"39-43"},"PeriodicalIF":0.0,"publicationDate":"1996-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20010359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, measurement of the RNA content of reticulocytes makes possible the identification of the youngest highly fluorescent macroreticulocytes (HFR) prematurely delivered from bone marrow in conditions of increased erythropoietic stimulation. The aim of this study was the definition, using the dedicated flow cytometers Sysmex R-1000 or R-3000 (Toa Medical Electronics Ltd, Kobe, Japan), of reticulocyte absolute number and HFR percentage in patients with haematological disorders prior to any treatment. Analysis of 54 healthy subjects and 100 untreated patients with five types of haematological disease is presented. In haemolytic anaemias (15 cases) both the reticulocyte count and HFR were greatly increased and the reticulocyte count was inversely correlated with Hb level, as in the reference population. In polycythaemia vera (20 cases) reticulocytes were moderately increased and directly correlated with Hb. In dyserythropoietic syndromes (20 cases) reticulocytes were low and HFR moderately increased; HFR showed an inverse correlation with Hb. In acute myeloid leukaemia (30 cases) reticulocytes were low and HFR increased; reticulocytes correlated with both HFR and Hb. In acute lymphoid leukaemia (15 cases), while the reticulocyte count did not differ from the reference group, the HFR was increased. These results provide reference values for the evaluation of reticulocyte counts and HFR in haematological diseases. From a physiopathological standpoint, they suggest that in anaemic patients the reticulocyte count directly reflects effective bone marrow erythrocyte production, while the proportion of circulating HFR more closely reflects the intensity of erythropoietic stimulation.</p>","PeriodicalId":10285,"journal":{"name":"Clinical and laboratory haematology","volume":"18 Suppl 1 ","pages":"29-34"},"PeriodicalIF":0.0,"publicationDate":"1996-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20012536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
