[Blood count results from hypertensive patients seen in laboratory of CHU-HJRB Antananarivo in 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 31 th 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.
