Hémogramme chez les hypertendus vus au laboratoire du CHU-HJRB d'Antananarivo en 2013

INTRODUCTION: The blood count is a routine laboratory test prescribed to patients suffering from high blood pressure. This study aims to describe the results of blood count from hypertensive patients and to identify conditions associated. METHODS: This retrospective and descriptive study concerns the period from the 1st of December 2012 to 31th of December 2013 in the laboratory of University Hospital Center CHU-HJRB of Antananarivo. All records of results from hypertensive patients who requested blood count have been exploited. RESULTS: Among 151 hypertensive patients, 91 (60.3%) had pathological blood counts. Of these, 64 (70.4%) showed one type of abnormality and 27 (29.6%) had multiple abnormalities. The anaemia (33.91%), the leukocytosis (33.04%), the polycythemia (10.43%) and the leukopenia (9.57%) are the most frequent. Among the multiple abnormalities, anaemia associated with leukocytosis is the most observed (29.6%). The microcytosis anaemia (41%) and the neutrophil polymorphonuclear leukocytosis are the most dominant (47.4%). Patients in nephrology (90%) and in endocrinology (81.3%) are the most concerned (p = 0,008). Hypertensive under 20 years old (100%) and women (61.5%) are the most affected (p > 0, 05). The seizures (100%), the edema of the lower limbs (100%) and diabetes (70%) are the signs and pathology most encountered. CONCLUSION: The blood count should be prescribed for all hypertensive patients to identify the affections that will be treated simultaneously with the high blood pressure. Thus, hypertensive patients will have a good follow-up and their life expectancy will be improved.
