Background:Eosinophilic fasciitis (EF) is an uncommon chronic inflammatory disease characterized by myalgia, soft tissue hardening, peripheral eosinophilia and increased acute phase reactants, often triggered after strenuous physical exercise. Its appearance has been described as a rare complication after allogeneic transplantation of hematopoietic progenitors in the context of chronic graft-versus-host disease (cGVHD). Its etiopathogenesis is not well known and usually the treatment with systemic corticosteroids is effectiveObjectives:Describe the clinical and transplant-related characteristics of a cohort of patients with eosinophilic fasciitis-like in the context of cGVHDMethods:Observational, retrospective and descriptive study of the clinical characteristics of 28 patients affected by EF-like followed in a multidisciplinary consultation of cGVHD, started in March, 2014. Regular demographic variables, clinical characteristics related to the transplant and with the cGVHD, laboratory parameters, rescue therapies and their response were collected. The statistical analysis was done with Microsoft Excel 2007.Results:Seventeen (60.7%) patients were male and 11 (39.35%) were women with a mean age of 48.75 years (range from 10 to 74). Acute myeloid leukemia was the most frequent cause of the transplant in 11 patients (39.3%). Transplant related characteristics are reflected in Table 1 and the clinical manifestations, therapies received and their response in Table 2. Four (14.2%) patients died during their follow-up, being the cause of death in 2 cases due to sepsis, and in 1 case attributable to GVHD.Table 1.Baseline and transplant related characteristics (N = 28)..VariablesN (%)Donor Type (related / not related)13(46.4%)/15(53.6%)Type of conditioning (reduced intensity / myeloablative)18(64.25%)/10(35.7%)Source of cells (Peripheral blood / bone marrow)27(96.4%/1(3.6%)cGVHD type quiescent / de novo / progressive11(39.3%)/13(46.4%)/4(14.3%)Other affected organs (cGVHD score)-Mouth6(21.4%)-Eyes10(35.7%)-Lung2(7.1%)-Liver3(10.7%)-Gastrointestinal tract0(0%)-Genital2(7.1%)-Cutaneous16(57.14%)Global ScoreNIH1(mild / moderate / severe)4(14.2%)/14(50%)/10(35.7%)1NIH: National Institute of Health.Table 2.Clinical manifestations and therapies (N = 28)..VariablesN (%)/Median (range)Prodromic symptoms: yes / no20(71%)/8(29%)- Stiffness2(7.1%)- Artromyalgia17(60.7%)- Edema3(10.7%)Time until first visit31.3 months (range 9-73)Contracture Yes / No18(64.3%)/10(35.7%)Mobility limitation (mild / moderate)13(46.4%)/9(32.1%)ECOG1affected11(39.2%)Eosinophilia17(60.7%)Positive autoantibodies8(28.5%)First line therapies (corticosteroids)28(100%)Extracorporeal photoapheresis19(67.9%)Therapies of 2nd line/ 3rd or more6(21.4%)/12 (42.8%)Physiotherapy14 (50%)Response: complete / sequels10(35.7%)/18(64.2%)1ECOG: Eastern Cooperative Oncology Group scale to assess the quality of lifeConclusion:Nonspecific joint symptoms such as stiffness, edema or arthromyalgia in patients undergoing allogeneic transplantation of hematopoietic progenitors may be factors that predict the development of sclerotic GVHD type eosinophilic fasciitis-like and should be closely monitored in order to be able to perform early stage diagnoses of the disease. It is necessary to deepen the pathogenesis of this entity and the multidisciplinary approach to improve the prognosis of patients with GVHDReferences:[1]Inamoto Y.
