| To evaluate the effect of different patient demographic factors on total weekly warfarin
maintenance dose formula {12.34+ (0.69xBMI)} in antiphospholipid syndrome Jordanian patients.
Methods: Our prospective observational study included 112 patients, of both sexes, aged 29-64years,
classed II-III physical status by the American society of anesthesiologists and presented to the
rheumatology clinic as antiphospholipid syndrome labeled subjects during the year 2013 at King Hussein
hospital, King Hussein medical city, Amman, Jordan, after obtaining approval from our local ethical
board review committee of the royal medical Jordanian military services. Patients were divided into
warfarin dose group I (n= 56, ≥70mg) and warfarin dose group II (n=56, ≤50mg). Patients with target
INR ranges of 2.5 to 3.5 only were included. Demographic patients data were related to target INR and
with the warfarin weekly maintenance dose {12.34+ (0.69xBMI)} .
Results: The mean age was 31.5 years(range of 29-34 years) in group I and 46 years(range of 32-60
years) in group II(P<0.05) The female preponderance was 43(76.8%) in group I and 21(37.5%) in group
II.P<0.05. The mean BMI was 38.3kg/m2 (range of 32.2-39.1) in group I and 28.4kg/m2 (range of 25.6-
29.5) in group II. Patients presented with target INR were 49 patients (87.5%) in group I and 52 patients
(92.9%) in group II. The mean total weekly warfarin dose in group II was 38.1 mg and the mean dose in
group I was 62.5 mg.
Conclusions: Female young Jordanian antiphospholipid syndrome labeled patients need less total
weekly warfarin maintenance dose to achieve INR target of 2.5-3.5 and that the formula cannot be applied
on this group. |
