ABSTRACT
BACKGROUND: Mucous membrane pemphigoid (MMP) still represents a potentially life- and sight-threatening disease. Immunosuppressants, such as cyclophosphamide (CYC), are indicated for patients with severe and/or refractory MMP. OBJECTIVES: To evaluate the efficacy and safety of daily oral CYC without corticosteroids as therapy for severe MMP. METHODS: Thirteen patients with severe refractory MMP, who received oral CYC at an initial dose of 2 mg kg(-1) without corticosteroids, were retained. Previous treatments, for example dapsone, sulfasalazine or topical agents, were maintained during CYC treatment. Initial clinical severity and response to treatment were assessed by scoring. CYC was stopped after complete remission (CR), or when MMP progressed or lymphopenia (< 0·7 × 10(9) cells L(-1) ) occurred. RESULTS: After 52 weeks of CYC treatment, the overall response rate was 69% (9/13 patients) with a median time to disease control of 8 weeks (range 4-52 weeks). Seven patients (54%) entered CR with a median time to CR of 24 weeks (range 16-52 weeks), all remaining in CR at week 52. The mean duration of CYC administration was 12 weeks (range 2-52 weeks). The most common side effect was lymphopenia (10/13 patients), which led to CYC withdrawal for six patients. No sepsis was observed. CONCLUSIONS: CYC without corticosteroids had rapid efficacy in patients with severe refractory MMP and was safe.

BACKGROUND: Patients with cancer are at a high risk of thromboembolism (TE), which contributes to morbidity and mortality. Several case reports of thromboembolic events have been reported in patients with melanoma in the literature. OBJECTIVE: The aim of this study was to evaluate the prevalence of venous thromboembolism (VTE) in stage IV melanoma and determine risk factors, outcomes associated with the development of VTE and the number of haemorrhagic complications in patients under anti-coagulant treatment. PATIENTS AND METHODS: In this retrospective study, we included all consecutive patients with stage IV melanoma among 290 patients followed-up in the department of Dermatology each year between January 2005 and 31 December 2007. The diagnosis of VTE was confirmed by venous ultrasound, pulmonary perfusion-ventilation technetium scan and angiography. The primary outcome was to evaluate the number of TE diagnosed in stage IV melanoma patients. The secondary outcomes were to study the influence of TE on survival, its prevalence according to metastatic sites and to evaluate the number of haemorrhagic complications. RESULTS: Twenty-four VTE events were found [25.2% (CI: 16.5-34)]. Eighteen VTE were deep venous thrombosis in lower limbs associated with pulmonary embolism (PE) in 50% of cases. Twenty-five percent were asymptomatic and were revealed in the pulmonary scan performed for follow-up. Eight percent of VTE events revealed stage IV melanoma. Seventeen patients developed thrombosis at home after stopping heparin prophylaxis. Seven thrombotic events occurred during oral anti-coagulant therapy. CONCLUSION: We found as high a prevalence of VTE in stage IV melanoma as in lung and gastrointestinal cancers. All patients suffered thrombotic events when they were treated with chemotherapy and at home when they stopped heparin prophylaxis. Therefore, heparin prophylaxis should be maintained at home.
