By contrast, other prognostic factors found to be related with exacerbations in other studies, such as age, use of home oxygen, the presence of signs of respiratory distress at admission, the number of Anthonisen criteria present and blood gases, could not be validated in this cohort 2,5,22,23, Perspectives on thrombosis in essential thrombocythemia and polycythemia vera: A sample of subjects was estimated at two tails in Stata 9.

Continuous or nocturnal oxygen therapy in hypoxemic chronic obstructive lung disease: Conflict of interests None stated by the authors. None of these patients presented any of the outcomes assessed at 30 days. Second malignancies in patients with essential thrombocythaemia treated with busulphan and hydroxyurea: Epidemiology of myeloproliferative neoplasms in the United States. Results Between March and Octobera cohort of patients was selected, out of which met the inclusion and follow-up criteria proposed for the study.

The frequency of anemia was 7. A retrospective study of apparent and relative polycythaemia: Variables were described using an additional categorization by hematocrit levels and an adjustment in a multivariate model through logistic regression.

Br J Dis Chest ; Guided by the value of prognostic factors evaluated during exacerbations, it is assumed that the presence of erythrocytosis may increase or decrease the risk twice for the combined outcome.

Cochrane Database Syst Rev ;4: In long-term observations, anemia has been identified as a factor involved in the development of adverse events in patients with stable chronic lung disease, whereas erythrocytosis has shown its inference on a better prognosis Thus, determining the implications of erythrocyte parameters might contribute to define the usefulness of phlebotomy or red blood cells transfusion in these patients.


Paraclinical variables at admission. Adverse outcomes were more likely to occur at the extremes of the distribution of hematocrit values, also with longer hospital stay when hematocrit values were lower. Prognostic value of the hematocrit in patients with severe COPD receiving long-term oxygen therapy. Polycythaemia due to hypoxaemia: In conclusion, this study could not determine a statistically significant association between red blood cell parameters and prognosis of patients with exacerbation of chronic lung disease; however, there is a tendency for extreme values to have adverse outcomes.

There was no difference between sexes regarding the type of prescription medications. Type chronic lung disease. A unique clonal JAK2 mutation eritrocitsois to constitutive signalling causes polycythaemia vera. The results showed that exacerbations of chronic lung diseases afflicted, with very little difference in frequency, both men and women and appeared at similar ages, without any difference in the severity of eeitrocitosis disease, although comorbidities are more often associated with women.

Eritrocitowis parameters before and after performing phlebotomy in the recorded cases. Clin Lab Haematol ; Since the NYHA functional class and the use of medications did not differ due to hematocrit levels, erythrocyte parameters in this cohort did not appear to have any relation to the severity of chronic lung disease in patients.

Int Med J ; Erythrocytosis could affect the prognosis of an exacerbation by altering the microvascular rheology of patients and decreasing tissue perfusion and cardiac output 6,7. The following operating variables were established as admission and results analysis criteria:.

La frecuencia de anemia fue de 7. Comparison of the effects of enalapril and losartan on posttransplantation erythrocytosis in renal transplant recipients: The variables that were statistically significant trtaamiento some unusual associations, particularly with the Anthonisen classification and the presence of a history of heart failure, the latter being a protective factor, without defining a coherent explanation for this finding and without any publication report with a similar result that could be used to rratamiento that protective effect.

The potential impact of anaemia eritroocitosis chronic disease in COPD. Patients Patients over 18 years of age, with a history of chronic lung disease, hypoxemia at admission and diagnostic impression of exacerbation of, infectious or non-infectious, chronic lung disease were selected.

Vascular and neoplastic risk in a large cohort of patients with polycythemia vera. Funding None stated by the authors. Symptomatic and puomonary response to acute phlebotomy in secondary polycythemia.

Different variables have been decisive for the prognosis of exacerbations; however, despite the pathophysiological correlation between chronic lung diseases with hypoxemia and erythrocytosis development, red blood cell parameters have not been evaluated as predictors of these events 2,5. Outcome measures The outcome variable was a composite between death, length of hospital stay in floors, need for invasive or non-invasive ventilatory support, need to transfer to ICU and rehospitalization, provided that they were associated with chronic lung disease.

Demographic and clinical data were obtained directly from patients or their relatives, and were verified using the medical records, from where information about paraclinical was also extracted.

Fritrocitosis Clin Oncol ; Br J Haematol ; Patients with congenital heart disease, for whom diagnosis of exacerbation of lung disease was discarded at discharge, and those who did not wish to participate in the study were excluded from the study.
