[Aspergillosis in systemic diseases treated with steroids and/or immunosuppressive drugs: report of 9 cases and review of the literature].

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.

[Interest of an internist's consultation in uveitis. Comparative study in 66 cases].

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.

[Carcinoma of unknown primary site].

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.

[Lemierre syndrome variant: Hepatic abscesses and hepatic venous thrombosis due to Fusobacterium nucleatum septicemia].

INTRODUCTION: Like Fusobacterium necrophorum, Fusobacterium nucleatum is capable causing Lemierre's syndrome. Various locations of venous thrombosis have been described associated with Fusobacterium sp. septicemia. EXEGESIS: We describe a 43-year old alcoholic patient with F.nucleatum septicemia complicated with hepatic abscesses, middle hepatic venous thrombosis, osteomyelitis and infiltrative pneumonia. A pancreatic prosthesis was the only potentially identified infectious entrance. CONCLUSION: Our patient showed an alternative presentation of Lemierre's syndrome, a "digestive variant". To the best of our knowledge, this is the first report of Fusobacterium septicemia associated with hepatic venous thrombosis. This report is close to the cases of portal thrombosis and opens the clinical sphere of the lemierre's syndrome, whose incidence is increasing.

Treatment of isolated severe immune hemolytic anaemia associated with systemic lupus erythematosus: 26 cases.

The aim of this study was to evaluate the response to treatment and the long-term outcome in a cohort of patients in whom severe autoimmune hemolytic anaemia (AHA) was the leading manifestation of systemic lupus erythematosus (SLE). Twenty-six women with severe isolated AHA were included. Corticosteroids were used as the initial treatment for all patients in our study. An initial response was obtained in all but one patient (96%). The overall recurrence rate was three per 100 person-years, with an expected recurrence-free proportion of 73% with a 180 months median follow-up. Seven patients (27%) experienced a relapse of AHA. We found a higher proportion of pleuritis in relapsing patients. Only three patients experienced multiple relapses despite splenectomy and several immunosuppressants. Steroid-sparing effect of hydroxychloroquine and azathioprine could not be assessed because most of the patients received these treatments for other reasons than AHA. Intravenous immunoglobulins induced transient response in three cases. Splenectomy was efficient to definitively control AHA in one patient but two patients quickly experienced relapses while one patient did not benefit. Five patients received immunosuppressants that induced only transient responses. Rituximab was long-term efficient in one case. In conclusion, severe AHA is a serious complication of SLE that warrants appropriate management. On the basis of our experience, the ideal treatment of isolated AHA should be oral corticosteroids in first-line treatment. Our study does not support an important role for splenectomy. Patients refractory to conventional therapy should be treated either with few toxic immunosuppressive drugs, danazol or rituximab.

[Common variable immunodeficiency with autoimmune manifestations: study of nine cases; interest of a peripheral B-cell compartment analysis in seven patients].

PURPOSE: Autoimmune manifestations (AIM) are associated to common variable immunodeficiency (CVI) in about 20 to 25% of the cases. This study presents the clinical, biological characteristics and the evolution of nine patients developing CVI and AIM. A peripheral B-cell compartment analysis has been performed in seven cases. METHOD: This multicenter retrospective study analyses nine patients, six men and three women, within a population of 32 CVI. RESULTS: The mean age was 27 years at the time of diagnosis of AIM and 30 years at the time of diagnosis of CVI. The diagnosis of AIM preceded the diagnosis of CVI in five cases. Thirteen AIM of different types were observed: autoimmune hemolytic anemia (AHA, 3), immune thrombocytopenic purpura (ITP, 2), Evan's syndrome (2), primary biliary cirrhosis (1), rheumatoid arthritis (1), alopecia totalis (1), myasthenia gravis (1). The peripheral B-cell compartment was investigated in seven patients: five patients with autoimmune cytopenia presented with a diminution of memory B cells (CD27+IgD-) and immature B cells (CD21-) levels; the patient with primary biliary cirrhosis and myasthenia gravis had only a diminution of memory B cells level; the last patient with ITP presented with a normal level of memory B cells. Five among the seven patients with autoimmune cytopenia required a specific treatment using corticosteroids, high dosages of intravenous immunoglobulin, then splenectomy after failure of the medical management, with severe infectious complications in one case. CONCLUSION: The association of AIM and CVI is not fortuitous. The most common AIM is autoimmune cytopenia. The peripheral B-cell compartment analyses show that a majority of patients have a defect in memory B-cells. Treatment regimens are not standardized and splenectomy increases the risk of infectious complications.

Carbimazole induced eosinophilic granulomatous vasculitis localized to the stomach.

Vasculitis associated with anti-neutrophil cytoplasmic antibodies has been reported in patients treated with anti-thyroid drugs and especially propylthiouracil. We report here a case of granulomatous eosinophilic vasculitis mimicking gastric neoplasm and peripheral eosinophilia in a 27-year-old man who was treated with carbimazole for 5 months for Graves' disease. Clinical and morphologic features resolved within 2 months after stopping the drug, suggesting a causative role for the drug. To our knowledge, this is the first biopsy-proven granulomatous eosinophilic vasculitis associated with this drug.

[Systemic manifestations of Parvovirus B19 infections].

PURPOSE: Parvovirus B19 (B19) causes many clinical disorders, of which the most common are erythema infectiosum, aplastic crisis complicating chronic hemolytic anemia, and hydrops fetalis. In young adults, the skin eruption caused by B19 is accompanied by polyarthritis and polyarthralgia in 60% of the cases. Rheumatoid factors and other antibodies including antinuclear antibodies, anti-ADN, and antiphospholipids can be produced in the wake of B19 infection. CURRENT KNOWLEDGE AND KEY POINTS: These features may simulate systemic diseases as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) (lupus-like eruption over the cheeks, cytopenia, etc.) or vasculitis (purpura, renal involvement). In addition, there have been a few reports of SLE, vasculitis and other connective tissue diseases developing shortly after a B19 infection associated with virus clearance suggesting that B19 can act as a trigger of systemic disease. However, studies in large series indicate that in fact B19 is probably an extremely rare cause of RA, SLE or vasculitis. FUTURE PROSPECTS AND PROJECTS: In fundamental studies B19 interacts with inflammatory cells by regulation of cytokines. More recently, two studies suggest that viral infection due to B19 may affect the course of SLE, leading to specific biological subsets. These preliminary findings require confirmation to elucidate the significance of the presence of B19 in systemic disease.

[Systemic lupus erythematosus with disease onset after age 65].

OBJECTIVES: Systemic lupus erythematosus with disease-onset in the elderly has rarely been studied (only one report about 21 patients with disease onset at 65 and older). Is the management of this pathology modified in this population? METHODS: Seventeen hospitalised cases of lupus patients with disease onset at 65 or older are retrospectively reported between 1988 and 2000. The results are compared with those of younger subjects. RESULTS: The female to male ratio is 1.83. Mean age at disease onset is 71.9 +/- 3.5 years. Mean duration of follow-up is 3.5 +/- 2.4 years. Main initial symptoms are: deterioration of general status (41%), arthritis (35%), cutaneous manifestations (35%), thrombo-embolism (24%) and pleuritis (18%). Malar rash is uncommon (12%). Nephropathy is never a revealing symptom and is rarely serious during the disease's evolution. Like in neurologic manifestations, the etiology has to be discussed in relation to associated co-morbidities. Concerning haematologic features, lymphopenia is found in 82% of the cases with a questionable specificity. Antinuclear antibodies are constant, anti-dsDNA antibodies are found in 82% of the cases, antibodies to extractable nuclear antigens in 50%, and anticoagulant circulating activity in 59%. Prognosis is difficult to assess in such a limited series but 5-years survival probability is 83%. Glucocorticoid lead to 50% of major complications. CONCLUSIONS: This study focuses on the particular initial manifestations of systemic lupus erythematosus in the elderly (deterioration of general status, thrombosis, unusual cutaneous symptoms), and on the specificity of differential diagnosis and treatment.

[Adult Kawasaki disease].

PURPOSE: Review of the literature on adult Kawasaki disease. CURRENT KNOWLEDGE AND KEY POINTS: Kawasaki disease is an acute multisystemic vasculitis affecting predominantly young children. Several studies have suggested that Kawasaki disease is mediated by bacterial superantigens. The diagnosis is established on clinical criteria since no specific laboratory test yet exists for this disorder. The severity of Kawasaki disease relates to the possible occurrence of coronary aneurysms in 20% of childhood cases. Treatment with intravenous immunoglobulins before day 10 is recommended to prevent aneurysm formation. The occurrence of Kawasaki disease is unusual in adults and 52 cases only have been reported in adult patients. Seventy-one per cent of cases occur between 18 and 30 years. The incidence of specific clinical features is quite similar between adults and children. However meningitis and thrombocytosis are more common in children than in adults, while conversely both arthralgias and liver function abnormalities are more common among adults. Coronary aneurysms are less common in the adults with Kawasaki disease. Other diseases with similar clinical presentation such as drug hypersensitivity reaction and the toxic shock syndrome must be ruled out. Kawasaki disease is often diagnosed after the acute phase at the step of desquamation, when it is too late to expect any beneficial effect from immunoglobulins. FUTURE PROSPECTS AND PROJECTS: Diagnostic criteria of Kawasaki disease have not been validated in an adult population. Criteria of exclusion are necessary to eliminate toxic shock syndrome and drug hypersensitivity syndrome. An international retrospective study to collect data on epidemiologic, clinical, laboratory, and cardiovascular features of adult Kawasaki disease is necessary to validate specific diagnostic criteria and to improve the knowledge on this disease.
