Background.Dacarbazine(DTIC)is the first-line chemotherapy for metastatic malignant melanoma without cerebral metastasis.Its clinical and hematological safety is usually good.Hypersensitivity in hepatic failure patients is the most serious side effect described.Patients and methods.This was a retrospective study of the prevalence of hypersensitivity in patients treated with DTIC for metastatic melanoma between 11/01/2002 and 10/31/2003.Hypersensitivity was diagnosed in the event of fever,hypereosinophilia(>500/mm3)with or without liver dysfunction(> twice pre-therapeutic values).Clinical data,DTIC administration modalities,number of courses and clinical and laboratory safety data were recorded.Results.Twenty patients were included,11 women and 9 men of median age 58.6 years(22-82 years)with multiple metastases in all cases.DTIC was the first-line treatment for 19 patients,being administered for 4 days to 10 patients and for 1 day to the other 10 patients,depending on their overall health status.Five hypersensitivity-like manifestations were observed,all in the 4-day treatment group.In 3 patients,fever and hypereosinophilia were seen without liver dysfunction at D3 of the second course of treatment.In 2 patients,treatment was stopped after the second course because of disease progression.In the third patient,4 courses were given with recurrence of symptoms,although the latter were controlled during the fifth course with corticosteroids and antihistamines given 15 minutes before the start of treatment.Two patients experienced severe forms of hypersensitivity with fever,hypereosinophilia,liver dysfunction(cytolysis and cholestasis)and delayed medullar aplasia,after the first and second course respectively.In one patient,bone marrow examination showed a block at the promyelocytic stage consistent with a toxic etiology.Treatment with DTIC was stopped,and all signs regressed with symptomatic treatment.Discussion.Hypersensitivity with DTIC seems to be frequent,being observed in 20%of our patients,with early onset(after the first or second course)and absence of dose-dependence.We describe for the first time two cases of medullar aplasia occurring in association with DTIC hypersensitivity.During phase I studies,the hematologic toxicity of DTIC was moderate,rarely affecting red cells,and was observed with higher doses than those used in metastatic malignant melanoma.We suggest that this aplasia forms part of the signs of hypersensitivity because of the bone marrow morphology,the existence of anemia and concomitant resolution with all the others signs of hypersensitivity.Conclusion.Laboratory monitoring(NFS,liver enzymes)is thus justified,particularly after the first and second courses of DTIC.In case of fever and hypereosinophilia without liver dysfunction,DTIC may be continued together with symptomatic treatment.In the event of hepatic dysfunction,and of course severe hematological disorders,potentially fatal complications can occur and treatment must be stopped. 展开更多

In order to gain further insight on the role of Kaposi’ s sarcoma associated herpesvirus (KSHV) in classic and endemic Kaposi’ s sarcoma (KS) pathogenesis, we aimed to determine (i) whether KSHV is detectable in peripheral blood mononuclear cells (PBMCs), (ii) which PBMCs subpopulation harbor the virus, (iii) which clinical, histologic, and immunologic parameters are associated with KSHV viremia in a population of classic and endemic KS. KSHV viremia and various immunologic parameters were screened on 81 patients. KSHV viremia was positive in 58% of the patients. KSHV was detected in B cells, T cells, and monocytes. CD34+ cells depleted in circulating endothelial cells (CECs) were never infected and 50% of the patients tested had CECs infected by KSHV. We observed a significant increase of IL-2 and IFN-γ production by CD4 T cells and an increase of IFN-γ production by CD8 T cells compared to control patients. KS progression (P=0.001) and KS staging (P=0.03) were significantly and independently associated with positive KSHV viremia. Our results show that there is no specific immunosuppression in classic or endemic KS. We showed that KSHV can be detected within CECs and that KSHV viremia could be an indicator of circulating mature or precursor spindle cells. 展开更多

Background: Systemic capillary leak syndrome (SCLS) is a severe disorder characterized by unexplained rapid transferof considerable volumes of plasma from the intravascular to the extravascular compartment. For some cases of SCLS, no aetiology is evident and these cases are reported as idiopathic (ISCLS). Objectives: To describe the cutaneous findings in 3 patients with ISCLS. Results: Cutaneous involvement consisted in sclerosis, livedo, purpura and photodistributed maculopapular erythematous rash. Dermal mucinosis was proven by biopsy in 1 patient. No underlying disease was diagnosed during follow-up. Conclusion: The above-mentioned cutaneous findings can be present during acute attacks of ISCLS.They seem specifically related to the ISCLS and not indicative of an underlying disease. 展开更多
