Study Description
Brief Summary:
The purpose of this study is to determine whether HGF serum concentration might be raised in vivo by administering nadroparin given with prophylactic purpose to gynecological patients.

Condition or disease
Genital Diseases, Female Ovarian Neoplasms Urogenital Neoplasms

Detailed Description:

The study consisted of two phases. In the first phase, the main HGF pharmacokinetic parameters were evaluated, comparing a group of six women treated with a single dose of calcic nadroparin to a control group of six untreated women. Venous blood was drawn in both groups at 0, 30, 60, 90, 120, 150, 180, 240, 300, 360, 480 and 720 min. In the second phase, the HGF basal and maximum concentrations were measured in 17 women, undergoing one month of calcic nadroparin daily treatment. Venous blood was drawn twice on day 1 (at 0 and 90 min after nadroparin administration), then once on days 8 and 28 (at 90 min after LMWH injection). Calcic nadroparin was given subcutaneously at 2850 IU/0.3 ml anti-Xa.

Patients' characteristics:

In the first phase, 12 patients were enrolled, 6 treated with nadroparin for prophylactic anticoagulation and another 6 untreated as the control group. The six nadroparin-group patients were affected by benign pelvic gynaecologic diseases: three requiring laparoscopy and three laparotomy.

In the control group, four were healthy women volunteers and two patients submitted to gynaecological pelvic surgery, but these women were not treated with prophylactic LMWH.

In the second phase, 17 patients were enrolled among women planning gynaecological pelvic surgery and treated for 4 weeks with nadroparin for prophylactic anticoagulation. All these patients underwent laparotomy; ten were affected by malignancy (ECOC) and seven by benign (uterine fibroma, ovarian cystadenoma) pelvic gynaecologic diseases.

Groups and Cohorts

Nadroparin/control (phase 1)
patients affected by benign pelvic gynaecologic diseases were enrolled and treated with nadroparin for prophylactic anticoagulation; patients untreated with nadroparin were as control group.
Nadroparin (phase 2)
patients were enrolled among women planning gynaecological pelvic surgery and treated for 4 weeks with nadroparin for prophylactic anticoagulation. All these patients underwent laparotomy;
