Effects of 3 month therapy with danazol after laparoscopic surgery for stage III/IV endometriosis: a randomized study. (1/116)

The effect of treatment with danazol was evaluated with respect to expectant management after laparoscopic conservative surgery. All patients conservatively operated at laparoscopy for stage III-IV endometriosis from July 1994 to October 1996 were requested to enter the study. Patients who underwent surgery for recurrent endometriosis were excluded from the study, as well as patients who had taken hormonal therapies before laparoscopy. Informed consent was obtained from 77 women who were randomized after surgery to treatment with danazol 600 mg daily for 3 months (n = 36) or to expectant management (n = 41). All patients were regularly followed up every 6 months for evaluation of fertility, recurrence of pain symptoms and disease. During the follow-up, six (55%) of the 11 infertile women allocated to danazol and eight (50%) of the 16 given no treatment became pregnant (not significant). Moderate/severe pelvic pain recurred during follow-up in seven (23%) of the 31 women with pelvic pain allocated to the danazol group and nine (31%) of the 29 allocated to no treatment; the respective cumulative pain recurrence rates at 12 months were 26 and 34% (log rank test, not significant). Three women (8.3%) treated with danazol and six (15%) who received no treatment had disease recurrence as demonstrated by gynaecological examination and/or pelvic ultrasonography (not significant). Our results do not demonstrate a significant advantage of 3 month danazol therapy after laparoscopic surgery for stage III-IV endometriosis with respect to postoperative expectant management.  (+info)

Low-dose danazol after combined surgical and medical therapy reduces the incidence of pelvic pain in women with moderate and severe endometriosis. (2/116)

The most effective therapy for endometriosis is a matter for debate. The aim of the present randomized study was to evaluate the efficacy of low doses of danazol on recurrence of pelvic pain in patients with moderate or severe endometriosis, who had undergone laparoscopic surgery and 6 months of gonadotrophin-releasing hormone analogue (GnRHa) therapy. After surgery, 28 patients with moderate or severe endometriosis underwent therapy for 6 months with GnRHa i. m. every 4 weeks. They were then randomized into two groups: group A (14 subjects) was treated with 100 mg/day danazol for 6 months; group B (14 subjects, control) did not receive any type of therapy. After 12 months of treatment, group A had a significantly (P < 0.01) lower pain score than group B. There was no significant difference between the groups in oestrogen concentrations, bone mineral density or side-effects. The results suggest that low-dose danazol therapy reduces recurrence of pelvic pain in patients with moderate or severe endometriosis, treated surgically, and has few or no metabolic side-effects.  (+info)

Danazol treatment of idiopathic myelofibrosis with severe anemia. (3/116)

BACKGROUND AND OBJECTIVE: Severe anemia is an important problem in patients with idiopathic myelofibrosis (IM). When other therapeutic measures are unsuccessful or not applicable, 40-50% favorable responses are obtained with androgen therapy. Oxymetholone is the drug usually employed, but good results have also been reported with danazol, although the experience is limited to a few patients. The aim of the present study was to evaluate the effect of danazol on the anemia of IM. DESIGN AND METHODS: Seven out of 22 consecutive IM patients were eligible for danazol treatment because of severe anemia not treatable with (four cases) or refractory to (three cases) other therapies. Danazol (600-800 mg/day) was given orally for six months and thereafter progressively tapered to the minimum effective dose in responding patients or discontinued in non-responders. Complete response was considered cessation of transfusion requirements with normalization of hemoglobin (Hb) values; partial response was defined as a > 30% reduction in transfusional needs or an increase > 10 g/L in the Hb. The effect on platelet counts was also analyzed. RESULTS: One patient splenectomized three years earlier achieved a complete response and three a partial response, giving an overall response rate of 57 %. A significant increase in platelet counts was also observed in three responders. The responses were first seen between three and six months after the start of treatment, which was usually well tolerated. INTERPRETATION AND CONCLUSIONS: Danazol, given at an appropriate dosage for a sufficient time, is an effective treatment for a substantial proportion of IM patients with severe anemia without marked splenomegaly or who have been previously splenectomized.  (+info)

Is endometrial pre-treatment of value in improving the outcome of transcervical resection of the endometrium? (4/116)

The aim of this study was to determine whether or not the use of medical pre-treatment of the endometrium improves the outcome of transcervical resection of the endometrium with regards to long-term operative outcome, histological findings and patient satisfaction. A prospective randomized trial comparing three endometrial pre-treatment agents (danazol, medroxyprogesterone acetate or nafarelin) with no pre-treatment was conducted. The main outcome measures were: (i) thickness of the endometrium and myometrium resected; (ii) histological stage of the endometrium at the time of operation; (iii) the presence or absence of menses and (iv) patient satisfaction 1 year post-operatively. Of the three pre-treatments studied, danazol produced a lower median endometrial thickness than the control, showed the greatest ability to induce atrophy of the endometrial glands and stroma (not statistically significant) and produced the highest rate of amenorrhoea (not different to the control). Danazol and nafarelin produced significantly lower median endometrial thickness than no pre-treatment. There were, however, no significant differences in the rates of amenorrhoea in any of the pre-treatment groups compared with that in the control group. No improvement in clinical outcome or patient satisfaction is conferred by the use of medical pre-treatments if transcervical resection of the endometrium is performed in the proliferative phase of the menstrual cycle.  (+info)

Immunosuppressive therapy using antithymocyte globulin, cyclosporine, and danazol with or without human granulocyte colony-stimulating factor in children with acquired aplastic anemia. (5/116)

A prospective multicenter trial of 119 children 1 to 18 years of age with newly diagnosed aplastic anemia (AA) was conducted, comparing treatment using antithymocyte globulin (ATG), cyclosporine (CyA), and danazol (DAN) with or without rhG-CSF (400 microg/m(2), day on days 1-90). All children with very severe AA received rhG-CSF (VSAA group, n = 50). The other children were randomized to receive ATG, CyA, DAN, and rhG-CSF (G-CSF+ group, n = 35) or ATG, CyA, and DAN without rhG-CSF (G-CSF- group, n = 34). After 6 months, the hematologic response rate was 71%, 55%, and 77% in the VSAA group, G-CSF+ group, and G-CSF- group, respectively. There was no difference in the incidence of febrile episodes and documented infections between the G-CSF+ and G-CSF- groups. Bone marrow transplantation (BMT) was attempted in 22 patients in whom initial immunosuppressive therapy (IST; n = 18) failed or in whom a relapse occurred after an initial response (n = 4). Nineteen of the 22 patients are alive and well after a median follow-up of 18 months (range, 3 to 66 months) since BMT. The probability of survival at 4 years was 83% +/- 7% in the VSAA group, 91% +/- 5% in the G-CSF+ group, and 93% +/- 6% in the G-CSF- group. Myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) developed in one patient in each of the three groups; the overall risk for MDS/AML was 3% +/- 2% at 4 years. Because the results of IST were encouraging, it is suggested that children with AA receive IST as first-line therapy if there is no human leukocyte antigen-matched sibling donor.  (+info)

The possible anti-inflammatory role of circulating human leukocyte antigen levels in women with endometriosis after treatment with danazol and leuprorelin acetate depot. (6/116)

BACKGROUND: Endometriosis is defined as an inflammatory condition of the female reproductive tract, a state often associated with infertility and miscarriage. Many exogenously administered factors (treatments) control the disease via as yet unknown pathways. Possible candidate molecules involved in these mechanisms could be the serum-soluble human leukocyte antigens (sHIA) that have been detected in a variety of human body fluids and that are associated with several diseases. AIMS: We here examine how danazol and leuprorelin acetate depot treatments exert their anti-inflammatory action. It is plausible that subtle alterations mediated by these treatments and in relation to sHLA may explain the pathophysiology of endometriosis and provide insights towards new therapeutic protocols. METHODS: Indirect enzyme-linked immunosorbent assay (ELISA), using specific monoclonal antibodies, determined serum-soluble class-I and class-II HLA levels. ELISA readings from treated women were compared with normal healthy subjects. RESULTS: Serum-soluble class-I and class-II HLA levels are statistically significantly lower (P < 0.001) in women with endometriosis than in the control groups. However, danazol but not leuprorelin acetate depot administration augments soluble HLA class I and class II (P < 0.01 and P < 0.001, respectively) to normal levels during the treatment period, an increase that may account for the anti-inflammatory effect and the remission observed. CONCLUSIONS: It is shown that one of the underlying causes of endometriosis may be the lack of both circulating class-I and class-II antigen levels. Danazol administration acts via an induced release of these antigens, whose presence correlates with the degree of the inflammatory alleviation obtained. We thus provide evidence that the inflammatory state of the disease appears to be associated with soluble HLA levels because, 3 months after ceasing therapy, the circulating antigens in the serum return to the same levels that correspond to the pathological condition.  (+info)

Danazol and limb-threatening arterial thrombosis: two case reports. (7/116)

Danazol is a synthetic androgenic steroid used clinically for the treatment of a wide variety of disorders. Although there is no extensive evidence that androgens are thrombogenic in humans, there are case reports of cerebral, coronary, and peripheral arterial thrombosis in young male athletes abusing anabolic-androgenic steroids. There are also two reported cases of arterial and venous thrombotic events attributed to danazol therapy. We report two additional cases of limb-threatening arterial thrombosis in patients undergoing danazol therapy, and suggest the possibility that danazol may be an independent risk factor for arterial thrombosis.  (+info)

Allogeneic stem cell transplantation for Evans syndrome. (8/116)

Evans syndrome is a rare disorder characterized by combined autoimmune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA). Standard treatments consist of transfusions, corticosteroids, splenectomy, IVIG, anabolic steroids, vincristine, alkylating agents, or cyclosporine. In a patient with refractory disease, an allogeneic hematopoietic stem cell transplant (HSCT) resulted in complete clinical and serologic remission for more than 30 months. Allogeneic HSCT may be the only current curative therapy for Evans syndrome but may also be complicated by significant toxicities.  (+info)
