RESUMO

INTRODUCTION: Spontaneous adrenal hemorrhages (AH) are a rare condition with no consensus about their management. METHODS: Patients were identified using the Medicalization of the Information System Program database, imaging software and a call for observations to internists, intensivists and obsetricians working at our institution. Adult patients whose medical records were complete and whose diagnosis was confirmed by medical imaging were included. RESULTS: From 2000 to 2007, 20 patients were identified, including 15 were women. The clinical onset of AH was non-specific. In five cases, AH occurred during pregnancy; four of them were unilateral and right sided. The etiology of the other fifteen (bilateral adrenal hemorrhage in 11) were as follows: antiphospholipid syndrome (n=8), heparin-induced thrombocytopenia (n=4), essential thrombocythemia (n=3), spontaneous AH due to oral anticoagulants (n=1), complication of a surgical act (n=3), and sepsis (n=3). In seven cases, two causes were concomitant. The diagnosis of AH was often confirmed by abdominal CT. An anticoagulant treatment was initiated in 16 cases. Ten of the eleven patients presenting with bilateral adrenal hematomas were treated using a long-term substitute opotherapy. One patient died because of a catastrophic antiphospholipid syndrome. CONCLUSION: The clinical onset of HS is heterogeneous and non-specific. The confirmatory diagnosis is often based on abdominal CT. The search for an underlying acquired thrombophilia is essential and we found in this study etiological data comparable to the main series in the literature. Adrenal insufficiency is most of the time definitive in cases of bilateral involvement.

RESUMO

The association between thymoma and autoimmunity is well known. Besides myasthenia gravis, which is found in 15 to 20% of patients with thymoma, other autoimmune diseases have been reported: erythroblastopenia, systemic lupus erythematosus, inflammatory myopathies, thyroid disorders, Isaac's syndrome or Good's syndrome. More anecdotally, Morvan's syndrome, limbic encephalitis, other autoimmune cytopenias, autoimmune hepatitis, and bullous skin diseases (pemphigus, lichen) have been reported. Autoimmune diseases occur most often before thymectomy, but they can be discovered at the time of surgery or later. Two situations require the systematic investigation of a thymoma: the occurrence of myasthenia gravis or autoimmune erythroblastopenia. Nevertheless, the late onset of systemic lupus erythematosus or the association of several autoimmune manifestations should lead to look for a thymoma. Neither the characteristics of the patients nor the pathological data can predict the occurrence of an autoimmune disease after thymectomy. Thus, thymectomy usefulness in the course of the autoimmune disease, except myasthenia gravis, has not been demonstrated. This seems to indicate the preponderant role of self-reactive T lymphocytes distributed in the peripheral immune system prior to surgery. Given the high infectious morbidity in patients with thymoma, immunoglobulin replacement therapy should be considered in patients with hypogammaglobulinemia who receive immunosuppressive therapy, even in the absence of prior infection.

RESUMO

INTRODUCTION: Gemcitabine-induced thrombotic microangiopathy is a rare event whose management is not yet consensual. The use of eculizumab could be of interest. CASE REPORT: A 68-year-old woman was treated by gemcitabine as adjuvant chemotherapy of a pancreatic adenocarcinoma. Two months later, the patient presented with mechanical hemolytic anemia, thrombocytopenia and high blood pressure that led to the diagnosis of thrombotic microangiopathy. Gemcitabine was stopped. Plasma exchange therapy was introduced since hematological and renal parameters had worsened. As clinical efficacy was insufficient, eculizumab was introduced at a dose of 900 mg per week 4 times, then 1200 mg every 2 weeks. Symptoms along with hematological and nephrological analysis were back to physiological standards after 7 intravenous injections. CONCLUSION: Eculizumab seems to be an effective treatment against gemcitabine-induced thrombotic microangiopathy in case of severe hematological and renal injuries associated with a lack of response to plasma exchange therapy.

RESUMO

OBJECTIVES: To describe the clinical features, treatment, and outcome of autoimmune diseases (AD) in a cohort of patients with thymoma. DESIGN: Pathological records from three university hospitals, between 2005 and 2011, were reviewed to identify patients with thymoma. Patients with thymoma and AD were compared with patients with thymoma without AD. RESULTS: 47/85 (55%) cases of thymoma had AD, including myasthenia gravis (MG) (n=33), Hashimoto's thyroiditis (n=4), Isaac's syndrome (n=3), Morvan syndrome (n=2), pure red cell aplasia (n=2), systemic lupus (n=2), lichen planus (n=2), and one case of each following conditions: aplastic anemia, autoimmune hemolytic anemia, Good's syndrome, pemphigus, autoimmune hepatitis, Graves' disease, limbic encephalitis, and inflammatory myopathy. Six patients (7%) presented at least 2 ADs. The median duration of follow-up after surgery was 60 months (40-78 months). In 32 patients, the diagnosis of AD preceded the diagnosis of thymoma, in 9 patients, thymoma was diagnosed at the same time as the AD and 7 patients had been operated on when they developed an AD. We found a significative difference on the Masaoka stage between the MG patients and the patients who present another AD (p=0.028). No risk factor for developing an AD after thymectomy was identified. CONCLUSIONS: We describe here the long-term follow-up of a large series of AD related to thymoma. Our results confirm previous data concerning AD occurrence in patients with thymoma and suggest that preexisting autoimmunity is not a risk factor for developing autoimmune manifestations after thymectomy.

RESUMO

AIM: To assess the clinical features and outcome of lymphoma when associated with sarcoidosis and to determine whether this association gives lymphoma a better prognosis. DESIGN: Multicentre retrospective cohort study. METHODS: Retrospective chart review. RESULTS: Twenty-one patients were included (9 males, 12 females). Median age at sarcoidosis diagnosis was 48 years (range: 24-68 years). In 14 cases, lymphoma occurred within a previously known sarcoidosis. Five patients received a concomitant diagnosis of sarcoidosis and lymphoma, whereas lymphoma preceded sarcoidosis in two patients. Three patients were diagnosed with Hodgkin's lymphoma and 18 patients with non-Hodgkin's lymphoma (diffuse large B-cell lymphoma (DLBCL) (n = 11), follicular lymphoma (n = 2), chronic lymphocytic leukemia/small lymphocytic lymphoma (n = 2), anaplastic large cell lymphoma ALK + (n = 1), angioimmunoblastic T-cell lymphoma (n = 1) and T-cell prolymphocytic leukemia (n = 1)). Thirteen patients were alive and in complete remission. Median age at the time of diagnosis of sarcoidosis was lower in patients with concomitant lymphoma compared with patients with sarcoidosis preceding lymphoma (34 years vs. 51 years, P = 0.01). Patients presenting with DLBCL associated with sarcoidosis were compared with DLBCL without sarcoidosis. No statistical difference was found in the risk of death or progression between the two groups (P = 0.685). CONCLUSIONS: We report here the largest series of lymphoma associated sarcoidosis patients. As opposed to previous studies, we observed a predominance of patients with DLBCL. Our study confirms the concept of the sarcoidosis-lymphoma syndrome. Large B-cell lymphoma does not have a better prognosis when associated with sarcoidosis.

RESUMO

BACKGROUND: Transverse myelitis is a rare complication of systemic lupus erythematosus (SLE). This retrospective multicentre study identifies the prognostic factors in a relatively large patient series. PATIENTS AND METHODS: Twenty patients fulfilled the SLE criteria of the ACR classification and the Transverse Myelitis Consortium Working Group. A severe neurological flare was defined as muscle strength grade <3/5 in more than half the muscle groups at the motor neurological level. Inability to run or another significant ambulation-unrelated disability was considered as 'unfavourable neurological outcome'. RESULTS: Myelitis was the first SLE symptom in 12 patients; in the eight others, it occurred 8.6 years (median delay) after SLE onset. Eleven patients presented severe neurological impairments. The treatment included corticosteroids in all patients associated with intravenous cyclophosphamide in 11 and/or hydroxychloroquine in 14. Unfavourable outcomes were observed in 53% of the patients at six months and in 28% at end of follow-up (median: 5.9 years). An initial severe neurological impairment and no cyclophosphamide use were associated with unfavourable neurological outcomes at six months and at end of follow-up, respectively. CONCLUSION: Transverse myelitis may reveal SLE or occur more than 10 years after SLE diagnosis. The initial severity of the neurological flare (with paraplegia) is the main prognostic marker. The study provides arguments for cyclophosphamide use.

RESUMO

PURPOSE: Infectious aortic aneurysms are rare conditions, being responsible of 2% of aortic aneurysms. Most published results are surgical case series concerning infected abdominal aorta. In this retrospective study, we assessed clinical features and outcome of patients presenting infectious thoracic aortic aneurysms. PATIENTS AND METHODS: Diagnosis was based upon a combination of imaging evidence for thoracic aorta aneurysm and evidence for an infective aetiology including a culture of a causative pathogen, or a favourable outcome with anti-infective therapy. Retrospective case series. RESULTS: Six men and one woman were included, with a mean age of 66 years. All the patient presented at least one cardiovascular risk factor or atherosclerosis localisation. Fever (71%) and chest pain (42%) were the most common clinical presenting manifestations. The causative pathogens were: Staphylococcus aureus (N=1), Salmonella enteritidis (N=3) and Candida albicans (N=1). The contrast-enhanced computed-tomography disclosed an aneurysm whose diameter reached more than 50 mm (N=5), that increased rapidly in size (N=5), or presented an inflammatory aspect of the aortic wall (N=4). Management was both medical and interventional: surgery (N=3) or endoluminal repair (N=4). Outcome was favourable in six patients; one patient died from aneurysm-related complications. CONCLUSION: Clinical manifestations revealing an infectious thoracic aneurysm are variable. Diagnosis should be considered in patients presenting a rapidly-growing aneurysm, especially in the presence of elevated acute phase reactants. Endoluminal repair constitutes a treatment option. The role of FDG-PET for diagnosis and follow-up remains to be defined.

RESUMO

PURPOSE: To report on the various clinical presentations, etiological diagnosis, prognosis and treatment of patients with scleritis evaluated at a tertiary care eye center. METHODS: Retrospective, monocentric study on a series of 32 patients in a tertiary center. RESULTS: The mean age of included patients with scleritis was 46.8 years (range, 22 to 77 years). Nineteen patients were women and 13 were men. Twenty-six patients (81%) had anterior scleritis (15 nodular, 8 diffuse and 3 necrotizing), six (19%) had posterior scleritis. Unilateral inflammation was present in 24 patients (75%). Twelve out of the 32 patients (37.5%) had an underlying systemic disease: granulomatosis with polyangiitis (n=3), Behçet's disease (n=2), unspecified inflammatory arthritis (n=2), psoriatic arthritis (n=1), ankylosing spondylitis (n=1), sarcoidosis (n=1), Cogan's syndrome (n=1) and ulcerative colitis (n=1). Six patients (18.8%) were suspected of having infectious disease with herpes virus: clinical context and positive treatment response with oral valacyclovir. Systemic agents and topical agents were required in 28 patients (87.5%). The first line therapy was mainly oral non-steroidal anti-inflammatory drugs in 15 patients (47%) and oral corticosteroids in 8 (25%). Immunosuppressive drugs were required in 6 patients. The mean follow-up was 16.3 months. Six patients (19%) had a decrease in visual acuity. CONCLUSION: The number of systemic disease in our series is similar to the main series in the literature. Treatment with valaciclovir might be effective in patients with suspected herpes simplex scleritis.

RESUMO

Although primary immunodeficiencies (PID) are typically marked by increased susceptibility to infections, autoimmune manifestations have increasingly been recognized as an important component of several forms of PID. Here, we discuss two forms of PID in which autoimmune cytopenias are particularly common and may be the first manifestation of the disease in adults: autoimmune lymphoproliferative syndrome (ALPS) and common variable immunodeficiency (CVID). Approximately one fifth of patients with CVID develop autoimmune diseases, and immune thrombocytopenic purpura (ITP) and autoimmune hemolytic anemia (AHA) are the most common. Since autoimmune cytopenias frequently precede the diagnosis of CVID, testing for immunoglobulin levels should be performed in patients diagnosed with AITP and AHA. Patients with CVID in association with autoimmune cytopenias have a "particular phenotype" with lower susceptibility to infection and higher susceptibility to autoimmune manifestations and, for patients with AHA, a more frequent development of splenomegaly and lymphoma. Corticosteroids and high doses of intravenous immunoglobulins (IVIg) seem to have the same efficacy as in idiopathic AITP and AHA. Splenectomy and rituximab are as effective as in idiopathic autoimmune cytopenias but are associated with an increased risk of severe infection and should, in our opinion, be considered only for those rare patients with "refractory diseases". The course and outcome of autoimmune cytopenias is not affected by supportive IVIg therapy. Autoimmune destruction of blood cells affects over 70% of ALPS patients. The median age of first presentation is 24 months of age, but with increasing awareness of this condition, adults with autoimmune cytopenias are now being diagnosed more frequently. Testing for ALPS should therefore be considered in young adults with unexplained Evan's syndrome. Patients usually respond to immunosuppressive medications, including corticosteroids. Unlike many patients with idiopathic autoimmune cytopenias, the cytopenias in patients with ALPS typically do not respond to IVIg. After corticosteroids, the immunosuppressive drug that is the most studied in ALPS patients is mycophenolate mofetyl. Rituximab and splenectomy are relatively contraindicated in ALPS because of an increase risk of severe infection and should be reserved for patients who fail all other therapies.

RESUMO

AIM: To assess clinical features, treatment and outcome of Hypothalamo-pituitary (HP) sarcoidosis and to determine whether HP is associated with a particular clinical phenotype of sarcoidosis. DESIGN: Multicentric retrospective study. METHODS: Retrospective chart review. Each patient was matched with two controls. RESULTS: Twenty-four patients were identified (10 women, 14 men). Their median age at the sarcoidosis diagnosis was 31.5 years (range: 8-69 years). HP involvement occurred in the course of a previously known sarcoidosis in 11 cases (46%), whereas it preceded the diagnosis in 13 patients (54%). All but two patients had anterior pituitary dysfunction, 12 patients presented with diabetes insipidus. The most common hormonal features were gonadotropin deficiency (n=21), TSH deficiency (n=15) and hyperprolactinemia (n=12). Magnetic Resonance Imaging (MRI) revealed infundibulum involvement (n=8), pituitary stalk thickness (n=12) and involvement of the pituitary gland (n=14). All but two patients received prednisone. After a mean follow-up of 4 years, only two patients recovered from hormonal deficiencies. MRI abnormalities improved or disappeared in 12 cases under corticosteroid. There was no correlation between the hormonal dysfunctions and the radiologic outcomes. Patients with HP sarcoidosis had significantly more frequent sinonasal localizations and neurosarcoidosis and required a systemic treatment more frequently than controls. CONCLUSION: Although HP sarcoidosis is unusual, physicians should be aware that such specific localization could be the first manifestation of sarcoidosis. HP involvement is associated with general severity of sarcoidosis. MRI abnormalities can improve or disappear under corticosteroid treatment, but most endocrine defects are irreversible.

RESUMO

INTRODUCTION: Hypereosinophilic syndromes rarely manifest as polyserositis. Imatinib mesylate is the reference treatment for myeloid variants of FIP1L1-PDGFRA-positive hypereosinophilic syndromes. A response to imatinib has also been reported in FIP1L1-PDGFRA-negative hypereosinophilic syndromes. CASE REPORT: We report a 25-year-old man who presented with a FIP1L1-PDGFRA-negative hypereosinophilic syndrome, with severe pericardial effusion and bilateral pleuritis. Imatinib mesylate at the dose of 100mg daily was started because of high-dose corticosteroids dependence. A response was noted after 15 days of treatment. Corticosteroids were discontinued after 7 months and the patient remained asymptomatic after 23 months of treatment. CONCLUSION: This report evidences the association of polyserositis with hypereosinophilic syndromes and the potential efficacy of imatinib mesylate even in FIP1L1-PDGFRA-negative patients.

RESUMO

BACKGROUND: In 2002, the French Federation of Comprehensive Cancer Centers published clinical practice guidelines (CPGs) for the management of carcinomas of unknown primary (CUP). METHODS: A controlled "before-after" study at two centers (experimental in Lyon, France and control in Edmonton, Canada) to assess the impact of CPGs on CUP management. Fifty-CUP patients treated in 2000-2001, i.e. before CPG publication, and 50 patients treated in 2003-2004, were analyzed for both centers. RESULTS: In both groups, compliance for diagnostic workup was the same before or after CPGs publication. Non-adenocarcinoma histology and performance status (PS) < 2 were independent factors for CPGs compliance. In the experimental group, 75% of patients underwent inappropriate investigations. The proportion of patients from this group with unfavourable clinicopathologic entity and PS < or = 1, who received cisplatin-based chemotherapy did not significantly change (2000-2001: 27% vs. 2003-2004: 37.5%; P = 0.45). However, most patients treated in the pre period received organ-specific regimens, while most patients treated in the post period received taxane or gemcitabine-based regimens. Patients from the control group generally received taxane/carboplatin. CONCLUSIONS: Our study show that simply distributing CUP CPGs did not change practice and underline the necessity to disseminate and implement CPGs, both to oncologists and organ-specialist physicians.

RESUMO

BACKGROUND: Spinal cord involvement in sarcoidosis is rare, occurring in <1% of patients with sarcoidosis. METHODS: We report seven cases of spinal cord sarcoidosis, seen in two French hospitals over a 13-year period. Presentation of disease, methods of diagnosis and response to treatment, with quantification according to the reduction of the modified Rankin scale (MRS), were noted. RESULTS: Six patients presented insidious paresthesias or weakness and one a sudden paraplegia. Average MRS at diagnosis was to 2. Spine MRI showed one or several intramedullary lesions in all cases. Diagnosis was confirmed by extra-neural tissue biopsies in all cases, including mediastinoscopy (two patients), coelioscopy (one patient), bronchoscopy (one patient), salivary gland biopsy (one patient) and skin biopsy (two patients). The average follow-up for the group was 49.4 months. All patients responded to corticosteroid therapy with a median reduction of MRS of one point. Five patients received immunosuppressive therapy: cyclophosphamide (two patients), methotrexate (two patients), azathioprine (one patient), mycophenolate mofetyl (one patient), with an inconstant benefit. Patients who received cyclophosphamide presented severe fungaemia. CONCLUSION: Based on our study and literature analysis, we propose an algorithm for treatment of spinal cord sarcoidosis.

RESUMO

Ectopic adrenocorticotropic (ACTH) syndrome is a rare condition, generally due to lung or carcinoid tumors. 18-fluorodeoxy-glucose positron emission tomography ((18)FDG-PET) can be useful where conventional localization techniques often fail. A 50-year-old man presented with sudden diffuse oedema, hypokaliemic alkalosis, Diabetes mellitus and high serum levels of ACTH and cortisol. Ectopic ACTH syndrome was confirmed leading to ketoconazole treatment. Chest-computed tomography only revealed an aspecific anterior mediastinal nodule that was hypermetabolic on the whole body-(18)FDG-PET. A thymic tumor was suspected and the patient had a thymectomy that revealed an atypical carcinoid tumor with pleural carcinosis. The postoperative course was favorable with clinical and biochemical remission of neoplastic Cushing's syndrome.

RESUMO

INTRODUCTION: Granulomatous myositis is a rare condition that has been described in association with sarcoidosis. In the absence of sarcoidosis or other underlying disease, a diagnosis of isolated granulomatous myositis is considered. OBSERVATION: A 61-year-old African man presented with progressive limitation in running and proximal atrophy of the lower limbs for the past year. Quadricipital muscle biopsy revealed non-caseating epithelioid granulomas and multinuclear giant cells. Whole body fluorodeoxyglucose positron emission tomography ((18)FDG-PET) revealed hypermetabolic activity of salivary and lachrymal glands, and mild hypermetabolism in the mediastinal lymph nodes. Minor salivary gland biopsy was consistent with sarcoidosis. CONCLUSION: To our knowledge, this is the first reported case of sarcoid myopathy demonstrating the diagnostic usefulness of (18)FDG-PET.

RESUMO

This is a multicentric retrospective study of aspergillosis in patients treated by corticosteroids and/or immunosuppressive drugs for systemic diseases and a review of the literature. Nine patients, 5 men and 4 women, mean age of 62.8 years old were included among which Horton's diseases (3 cases), systemic lupus erythematosus (2), polymyositis (1), microscopic polyangiitis (1), idiopathic thrombocytopenic purpura (1), rheumatoid polyarthritis (1). Aspergillosis occurred in average 28.4 month after the diagnosis of systemic disease, and 28 months after the beginning of its treatment: corticosteroids in all cases, at a dose of 50.8 mg/day (equivalent prednisone) in average, cyclophosphamide (2 cases), methotrexate (1), intravenous immunoglobulins (1), leflunomide (1). All cases were invasive or chronic pulmonary aspergillosis located in the lungs (6 cases), or in the brain (3). Revealing symptoms were mild and non specific. Lymphopenia was severe in most cases, in average 472 lymphocytes/mm3 and 283 CD4+/mm3. The diagnosis was confirmed 20.75 days after the first symptoms in invasive aspergillosis, and 18.5 months in the chronic pulmonary cases, by cultures in 7 cases (broncho-alveolar lavage: 4; cerebral biopsy: 3), and direct microscopy examination of broncho-alveolar lavage in 2 cases. Specific serology was positive in 4 cases. Patients were treated by voriconazole (4 cases), itraconazole (2), amphotericin B (1), association of caspofungin and voriconazole (1), successive voriconazole and itraconazole (1). Six patients recovered from aspergillosis with 10.8 months of following time, 3 patients died a few days after confirmation of the diagnosis. Fifty-four cases of the literature are analysed.

RESUMO

BACKGROUND: After exclusion of a masquerade syndrome, uveitis may be associated with infection, systemic diseases, specific ocular diseases, or may be drug-induced. In order to improve diagnostic strategy in uveitis, we performed a comparative study to assess the importance of internist and ophtalmologist's collaboration and we proposed a well-adapted diagnostic procedure. MATERIAL AND METHODS: A comparative study was performed in a tertiary centre. The population was divided in two groups. The first one was retrospective and consisted of patients treated at the Ophthalmology department of Croix Rousse Hospital from 1991 to 2002 without internist's collaboration. The second one was prospective and consisted of patients referred in the same centre in 2003 and 2004 with intervention of an internist. Patients of less than 18 years of age with pre-existent diagnosis, specific ocular diseases, toxoplasmosis infection, or with human immunodeficiency virus infection were excluded. RESULTS: Sixty-six patients were included. Anterior uveitis was the most frequent form (25 cases), followed by panuveitis (20 cases), posterior uveitis (14) and intermediate uveitis (7). The most frequent cause of uveitis was systemic disease (19 cases) followed by infection (7 cases) and neurological entities (4 cases). The rate of diagnosis was 30.3% without internist's intervention and 60.6% when patients were referred to an internist (P=0,01). The internist intervention was contributive in 75% of diagnoses. CONCLUSIONS: The internist intervention significantly enhances the rate of etiological diagnoses in uveitis. These results should further strengthen the internist/ophthalmologist collaboration for patients with uveitis.

RESUMO

PURPOSE: Carcinoma of unknown primary site is a common clinical syndrome, accounting for 2% of cancer patients. Diagnosis is a recurrent challenge for internists. Treatment is difficult and prognosis is still poor. This review presents one synthesis of diagnosis strategies and therapeutic trials. It envisages the interest of new molecular biology methods as well as therapeutic perspectives. CURRENT KNOWLEDGE AND KEY POINTS: Pathologic examination completed with immunohistochemical tests, and, depending on cases, with electron microscopy, cytogenetics, and molecular biology is a key-point for diagnosis. Diagnosis work-up, based on histological type and on individualization of some clinical presentation, proceeds in three steps. Positron emission tomography is recommended when a curative treatment is planed, particularly in cases of isolated metastasis. Functional status analysed using the performance status and simple biologic parameters (serum lactate dehydrogenase, serum alkaline phosphatase) permit us to assess prognosis. Chemotherapy is offered for patients with a good general health status. FUTURE PROSPECTS AND PROJECTS: Further evaluation of positron emission tomography, as well as cost-benefit analyses, is warranted. Further randomised trials are necessary to determine the optimal chemotherapy regimen in good-risk patients and the interest of chemotherapy in patients with poor-risk disease. Gene expression profiling and proteomic evaluation, as well as pharmacogenomic offer new investigation fields.
