CAYO, Emerson et al. HEMOGLOBIN LEVELS IN CHOROLQUE HIGHLANDERS AT 5000 MASL. Rev. Méd. La Paz [online]. 2020, vol.26, n.1, pp.32-37. ISSN 1726-8958.

Introduction. Hemoglobin values in a population depend on several variables, including altitude and time of residence. Populations living at high altitudes have peculiar hemoglobin levels, Tibetan hemoglobin levels are similar to those of sea level; while in Aymaras those are increased. Chorolque is a mining district located at 5000 masl and inhabited for 100 years approximately, in this sense, its hematological values require to be elucidated. Objective. To describe hemoglobin levels and prevalence of pathological erythrocytosis in Chorolque high altitude dwellers. Material and methods. Cross-sectional descriptive study carried out through a retrolective review of 1328 (men=1176, women=142) blood cell counts and epidemiological data. Preliminary normal hemoglobin parameters (males 17-20 g/ dl, females 16-19 g/dl) were established considering the altitude and hemoglobin levels in other high altitude populations. Erythrocytosis was considered when Hb was >18 g/dl in women and >19 g/dl in men. Results. The average age was 39 years for men and 45 years for women. A mean Hb of 18.5 g/dl in women and 20.8 g/dl in men were observed. Regarding the preliminary normal parameters, the mean Hb was 17.5 g/dl in women (n=83) and 18.0 g/dl in men (n=282). Additionally, 8 % of women reflected Hb <16 g/dl and 2 % of men Hb <17 g/dl. Erythrocytosis was considered in 34% of women and 74% ofmen, mean Hb of 20.7 g/dl and 21.8 g/dl respectively. Conclusion. The average hemoglobin levels in Chorolque highlanders evidences unreported hematological values in Bolivia. Biomolecular studies will allow to characterize normal hemoglobin values and pathological erythrocytoses in this population
