Atteinte osseuse axiale de la sarcoïdose.

INTRODUCTION: Sarcoidosis is a multi-systemic disease characterized by non-caseating granulomas. Bone involvement initially considered as rare and described as a peripheral osteitis of the hands and feet, has recently been reported on the axial skeleton. CASE REPORTS: We report 4 clinical observations of sarcoidosis (3 women, 1 man) with axial bone involvement located to the spine (n = 4), pelvic bone (n = 2), scapular bone (n = 2), sternum (n = 1), mandible (n = 1). Sarcoidosis was already diagnosed in 3 cases. Bone pain was the main symptom, related in 3 cases. Magnetic resonance imaging appeared to be the best imaging test Histological bone analysis revealed typical granulomatous lesions (n = 2). Treatment included corticosteroids (n = 4), hydroxychloroquine (n = 2), and methotrexate (n = 2), with a good efficacy on bone pain in symptomatic patients. CONCLUSION: These 4 cases, as well as recent literature, illustrate bone involvement of sarcoidosis on the axial skeleton. It is symptomatic in around 50% of cases but may be a source of significant disability. Differential diagnosis with neoplasm may require bone histological analysis. This condition appears to be responsive to usual treatments for sarcoidosis.

Haploidentical transplantation with post-infusion cyclophosphamide in advanced Hodgkin lymphoma.

We investigated the use of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) in the treatment of advanced Hodgkin lymphoma (HL). Sixty-two consecutive HL patients underwent haplo-HSCT. Unmanipulated stem cells and post-transplant cyclophosphamide were given to all patients as GVHD prophylaxis. At 100 days, the cumulative incidence of grades 2-3 and grades 3-4 acute GVHD was 23% and 4%, respectively. The chronic GVHD (cGVHD) cumulative incidence was 16%, with one patient experiencing severe cGVHD. The 3-year OS, PFS, relapse rates and 1-year non-relapse mortality (NRM) were 63%, 59%, 21% and 20%, respectively. Uncontrolled disease status and high hematopoietic cell transplantation comorbidity index (HCT-CI) were associated with lower OS, whereas PBSC was an independent protective factor. Uncontrolled disease and HCT-CI >2 was predictive for NRM. Finally, disease status other than CR was predictive of relapse. In conclusion, haplo-HSCT is a valid treatment in advanced HL, offering excellent rates of survival and acceptable toxicities.

T-replete haploidentical allogeneic transplantation using post-transplantation cyclophosphamide in advanced AML and myelodysplastic syndromes.

Unmanipulated haploidentical transplantation (Haplo-SCT) using post-transplantation cyclophosphamide (PT-Cy) represents an alternative for patients with high-risk diseases lacking HLA-identical donor. Although it provides low incidences of GVHD, the efficacy of Haplo-SCT is still questioned, especially for patients with myeloid malignancies. Thus, we analyzed 60 consecutive patients with refractory (n=30) or high-risk CR (n=30) AML or myelodysplastic syndromes (MDSs) who underwent PT-Cy Haplo-SCT. The median age was 57 years (22-73 years), hematopoietic cell transplantation comorbidity index was ⩾3 in 38 patients (63%) and Haplo-SCT was the second allogeneic transplantation for 10 patients (17%). Although most of patients received PBSC as graft source (n=48, 80%), we found low incidences of grade 3-4 acute (2%) and severe chronic GVHD (4%). Among patients with high-risk CR diseases, 1-year non-relapse mortality, cumulative incidence of relapse, progression-free and overall survivals were 20%, 32%, 47% and 62%, respectively. In patients with refractory disease, corresponding results were 34%, 35%, 32% and 37%, respectively. We conclude that PT-Cy Haplo-SCT could provide promising anti-leukemic effect even in the setting of very advanced diseases. Thus, it represents a viable alternative for high-risk AML/MDS patients without HLA-identical donor.

Disseminated Mycobacterium lentiflavum responsible for hemophagocytic lymphohistocytosis in a man with a history of heart transplantation.

Mycobacterium lentiflavum is a nontuberculous, slowly growing mycobacterium usually recognized as a contaminant. Here, we report a case of disseminated M. lentiflavum infection responsible for hemophagocytic lymphohistocytosis in a heart-transplanted man.

[Granulomatosis with polyangiitis (previously Wegener's granulomatosis) mimicking malingering]. / Forme pseudo-pathomimique de granulomatose avec polyangéite (anciennement maladie de Wegener).

INTRODUCTION: ANCA vasculitis may involve the skin and develop slowly without specific histology, and without autoantibodies. CASE REPORT: We report a 50-year-old woman who experienced bilateral mastectomy because of ulcero-necrotic, non-specific inflammatory cutaneous lesions of the breasts. First considered by others as a malinger patient, she developed oto-neurological lesions leading to the diagnosis of Wegener's granulomatosis. Five years later, specific antibodies of the disease were present. CONCLUSION: Cutaneous involvement by ANCA vasculitis can be isolated for a long time. Physicians must have a high degree of suspicion to avoid diagnostic delay of ANCA vasculitis.

[Clinical, laboratory, radiological features, and outcome in 26 patients with aortic involvement amongst a case series of 63 patients with giant cell arteritis]. / Caractéristiques cliniques, paracliniques et profil évolutif de l'atteinte aortique de la maladie de Horton : à propos de 26 cas d'aortite parmi 63 cas de maladie de Horton.

PURPOSE: Aortic involvement that occurs in temporal arteritis is probably underestimated because it is usually asymptomatic. The characteristics of giant cell arteritis with aortic involvement are still poorly described and the relationship between aortitis and vascular outcome of the disease has not been clearly delineated. The objective of this retrospective study of 63 patients with giant cell arteritis, including 26 with aortic involvement, was to compare the features of patients with and without aortitis, and to assess the contribution of CT-scan and FDG-PET-scan in screening for vascular disease, monitoring, and therapeutic management of patients. METHODS: This retrospective study was conducted in the internal medicine department of the university hospital in Marseille, France, from January 1, 2005 to September 30, 2011. Patients had at least three out of the five American College of Rheumatology criteria for temporal arteritis and aortic involvement was investigated in all patients using CT-scan. Aortic wall thickness greater or equal to 3mm was considered to be abnormal. RESULTS: Of 63 patients diagnosed with giant cell arteritis, 26 (41.3%) had aortic involvement diagnosed by aortic CT-scan. Age at diagnosis was significantly younger (66.8 vs 73.8 years; P=0.002) in the group with aortitis. Inflammatory dorsal and low back pain, signs of vascular disease of the upper limbs (P=0.009), and higher level of acute phase reactants were associated with aortitis. Aneurysmal lesions of the aorta were significantly more frequent in the group with aortitis. Twenty patients had both aortic CT-scan and FDG-PET-scan. For patients in whom aortic involvement was not demonstrated with CT-scan, FDG-PET-scan was always non-contributive. With corticosteroids, aortitis resolved within 6 months in all patients as evaluated by aortic CT-scan. However, aortitis persisted in 80% of cases at 6 months when evaluated with FDG-PET-scan, and in 66% of cases at 12 months, without influencing the treatment. CONCLUSION: This case series shows no specific features of aorta and its main roots involvement in giant cell arteritis, justifying a systematic screening by CT-scan. The high frequency of this arterial involvement could help physicians in the diagnosis of giant cell arteritis. Aortitis seems to be associated with vascular complications as highlighted by the frequency of aortic aneurysm and a case of early aortic dissection. Finally, the role of PET-CT-scan for screening vascular disease and therapeutic monitoring remains to be clarified.

[Relapsing meningitis and confusion: limbic encephalitis revealing Hodgkin's disease]. / Méningite et confusion fébrile à rechute: encéphalite limbique révélant une maladie d'Hodgkin.

INTRODUCTION: An observation of limbic encephalitis associated with Hodgkin's disease is compared with rare cases of the literature. The clinical presentation was relapsing episodes of febrile cognitive disorders with confusion and meningitis, curable after treatment of Hodgkin's disease. Recent concepts on limbic encephalitis are discussed. CASE REPORT: A seventy-five-year-old patient was hospitalized because of relapsing feverish confusion episodes with meningitis. During the year before his admission he had experienced four spontaneously regressive episodes of feverish confusion. Exploration of these episodes disclosed a paraneoplastic limbic encephalitis due to an underlying Hodgkin's disease. The treatment of Hodgkin's disease led to perfect recovery of cognitive function, so that the patient could drive his car. CONCLUSION: Lymphoproliferative disease, such as Hodgkin's disease, is a possible diagnosis in patients with limbic encephalitis. A dysimmune process underlying Hodgkin's disease might be operating in this association.

[Occupational exposure and systemic sclerosis. Literature review and result of a self-reported questionnaire]. / Evaluation de l'exposition toxique professionnelle de patients atteints de sclérodermie systémique. Revue de la littérature et résultat d'un auto-questionnaire.

Systemic sclerosis (scleroderma) is a rare auto immune disease. Its physiopathology, based on various mechanisms, involves a predisposing genetic background and some exogenous factors. Among them, the role of toxic products is highly suggested according to several case-control studies. The aim of this study is to review the literature concerning occupational exposure associated with scleroderma. This review is completed by the results of a self-reported questionnaire on occupational exposures sent to 82 scleroderma patients followed in Marseille. Scleroderma associated with silica exposure should be declared as occupational disease. Moreover, the role of other toxic agents such as solvents is highly suspected and scleroderma occurring in case of high exposure should also be declared. Our study performed in Marseilles showed a occupational exposure in 10% of cases (five patients having an occupational exposure that could be involved in the genesis of the disease). One had an occupational silica exposure and was declared as occupational silica disease. Other cases had various toxic exposures including solvents and two were declared as disease of occupational nature. Occupational exposure (labour and leisure) must be searched for when faced with a scleroderma patient for two reasons: the possible declaration of an occupational disease and a better knowledge on toxics involved in scleroderma.

Lymphoma-associated hemophagocytic syndrome: a rare cause of severe prerenal acute renal failure.

We report on a 79-year-old woman having hemophagocytosis and capillary hyperpermeability syndrome who presented with anuric prerenal acute renal failure. The patient eventually died of a hypovolemic shock. Post-mortem biopsies evidenced a highly aggressive B cell intravascular lymphoma without amyloidosis. Physicians should be aware of the risk of anuric prerenal acute renal failure in the course of lymphoma-associated hemophagocytic syndrome.

[Simultaneous occurrence of diffuse Takayasu's arteritis and severe disseminated tuberculosis]. / Survenue simultanée d'une artérite de Takayasu multifocale et d'une tuberculose sévère.

Links between Takayasu's arteritis (TA) and tuberculosis are discussed in the literature. We report the case of a Caucasian woman who was first seen for a regressive fever, associated with a normal clinical and chest and abdominal CT-scan examination. A minor granulomatous hepatitis was documented. She had no symptoms for the following four years. A second episode of persisting fever led to the diagnosis of simultaneous occurrence of diffuse TA and severe disseminated tuberculosis. Both affections were treated and the patient was still in good health after three years of follow-up. Simultaneous occurrence of both diseases in our observation supports evidence for a relationship between those two granulomatous diseases.

Overlap syndrome between FMF and TRAPS in a patient carrying MEFV and TNFRSF1A mutations.

OBJECTIVE: Familial Mediterranean Fever (FMF) and TNF-Receptor Associated Periodic Syndrome (TRAPS) are two inheritable inflammatory disorders. They share some clinical manifestations but their treatments are different. We present here the case of an overlap syndrome of FMF and TRAPS in a patient carrying a mutation in both the MEFV and TNFRSF1A genes. CASE REPORT: A 20-year-old woman of Mediterranean origin had suffered since childhood from attacks of fever and arthritis, with skin and ophthalmic manifestations. The initial diagnosis was FMF. The symptoms responded poorly to colchicine but regressed with steroids. Genetic analysis revealed a homozygous M694V mutation in MEFV and a heterozygous R92Q mutation in TNFRSF1A. We discuss the complexity of this combined FMF-TRAPS phenotype. CONCLUSION: This case shows that mutations in MEFV and TNFRSF1A can occur together in a single patient, a condition that may modify its response to treatment. It would be interesting to evaluate the role of the R92Q mutation in TNFRSF1A in patients of Mediterranean origin with FMF unresponsive to colchicine.
