RESUMO
OBJECTIVES: To report the safety and efficacy of tocilizumab in patients with severe and refractory non-infectious uveitis. METHODS: Eight consecutive unselected patients with severe and refractory non-infectious uveitis [Birdshot chorioretinopathy (n=1), Behçet's disease (n=1) and idiopathic bilateral panuveitis (n=6)] treated with tocilizumab (8mg/kg every 4 weeks intravenously) were included. The primary outcome was the response to treatment, defined by decrease of inflammatory ocular signs. RESULTS: Four (50%) patients were of female gender and the median (IQR) age was 41 (31-47) years. The median number of previous immunosupressants was of 5.5 (4-6.7). Seven patients had been previously treated with anti-TNF-α [infliximab (n=5) and adalimumab (n=2)]. The immunosupressive drugs used in association with tocilizumab were azathioprine (n=2), mycophenolate mofetil (n=2) and methotrexate (n=2). After a median follow-up of 8 months (6-25), 6/8 (75%) improved under tocilizumab and 2 (25%) were non-responders. The visual acuity improved in five patients. The median dose of prednisolone decreased from 16mg/day (10.6-20.5) to 10 mg/day (10-13.7), at baseline and at the end of follow-up, respectively. Tolerance of tocilizumab was satisfactory and side effects included bronchitis (n=1) and grade 1 leukopenia (n=1) and thrombocytopenia (n=1). CONCLUSIONS: Tocilizumab seems to be a safe and promising therapy in severe and refractory non-infectious uveitis.

OBJECTIVE: To describe the interplay between Behçet's disease (BD) and pregnancy. METHODS: This retrospective study included 76 pregnancies in 46 patients fulfilling the international criteria for BD. The median age of the patients at the time of entry into the study was 28.4 years (interquartile range 22.8-30.9 years). Patients were used as their own historical controls to assess the incidence of BD flares during pregnancy and before or after pregnancy. Factors associated with the occurrence of complications during pregnancy were assessed. RESULTS: Among the 76 pregnancies with BD analyzed, 27 (35.5%) were associated with worsening of the symptoms of BD flare; oral and genital ulcerations (78.4% and 67.6%, respectively) as well as ocular complications (32.4%) were the most frequent. The mean ± SD annual rates of BD flares were 0.49 ± 0.72 during pregnancy and 1.46 ± 2.42 during the nonobstetric period (P = 0.018). The proportion of BD flares tended to be lower in patients treated with colchicine (27.9% versus 45.4% of patients not treated with colchicine; P = 0.11). The overall rate of complications during pregnancy was 15.8%. The complications included miscarriage (5 patients), cesarean delivery (3 patients), medical termination of pregnancy (2 patients), hemolysis, elevated liver enzymes, and low platelets syndrome (1 patient), and immune thrombocytopenia (1 patient). There was a statistically significant association between a history of deep vein thrombosis in BD and the risk of obstetric complications (odds ratio 7.25, 95% confidence interval 1.21-43.46, P = 0.029). Neither gestational age at delivery nor neonatal outcome was influenced by BD. CONCLUSION: The disease course in BD seems to improve during pregnancy, mostly in patients who are treated with colchicine. Pregnancy in patients with BD appears not to be associated with an increased rate of pregnancy-related complications.

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans histiocytosis, with noncodified therapeutic management and high mortality. No treatment has yet been shown to improve survival in these patients. We conducted a multicenter prospective observational cohort study to assess whether extraskeletal manifestations and interferon-α treatment would influence survival in a large cohort of ECD patients. To achieve this goal, we thoroughly analyzed the clinical presentation of 53 patients with biopsy-proven ECD, and we performed a survival analysis using Cox proportional hazard model. Fifty-three patients (39 men and 14 women) with biopsy-proven ECD were followed up between November 1981 and November 2010. Forty-six patients (87%) received interferon-α and/or PEGylated interferon-α. Multivariate survival analysis using Cox proportional hazard model revealed that central nervous system involvement was an independent predictor of death (hazard ratio = 2.51; 95% confidence interval, 1.28-5.52; P = .006) in our cohort. Conversely, treatment with interferon-α was identified as an independent predictor of survival (hazard ratio = 0.32; 95% confidence interval, 0.14-0.70; P = .006). Although definitive confirmation would require a randomized controlled trial, these results suggest that interferon-α improves survival in ECD patients. This may be seen as a significant advance, as it is the first time a treatment is shown to improve survival in this multisystemic disease with high mortality.

OBJECTIVE: To describe the pseudotumoural presentation of neuro-Behçet's disease (NBD). METHODS: We report here the main characteristics, treatment and outcome of 23 patients (5 personal cases and 18 patients from the literature) with a pseudotumoural presentation of NBD. Pseudotumoural NBD patients were compared with 69 consecutive patients, with a classical form of NBD. RESULTS: The median age was 39 (range 27-48 years) years, with a male predominance (65.2%). Clinical features of the pseudotumoural NBD included hemi- or tetra-pyramidal symptoms (n = 20), headache (n = 17), cerebellar syndrome (n = 3), sphincter impotence (n = 3) and pseudobulbar signs (n = 2). CNS imaging showed pseudotumoural lesions mainly in the capsulo-thalamic area (69.6 vs 11.6% for classical NBD; P < 0.01). Histological analysis revealed necrotic lesions with perivascular inflammatory infiltrate without signs of tumoural or infectious lesions. Patients with pseudotumoural NBD had more severe initial disability status (Rankin's score ≥3 in 65.2 vs 24.7%; P < 0.01) and had a 3 years' longer duration between neurological signs and BD diagnosis (P = 0.01) compared with patients with classical NBD. Treatment consisted of CSs (n = 21, 95.5%) and immunosuppressive agents (n = 10, 35.7%) that led to complete clinical and imaging remission in 60.9% of patients. Two (8.7%) of the 23 patients with pseudotumoural NBD died of bedridden state complications. CONCLUSION: The pseudotumoural form of NBD is a rare and life-threatening condition.

OBJECTIVE: To analyse therapeutic management of eosinophilic fasciitis (EF). METHODS: We reviewed 34 adult patients with biopsy-proven EF. Analyses focused on the therapeutic management, including treatment modalities, responses and associated or predictive factors. RESULTS: Thirty-four patients were included with a diagnosis age of 53 (15) years. They were featured by cutaneous manifestations (88%) including morphoea (41%), myalgia (86%) and hypereosinophilia (85%). Thirty-two patients (94%) were eligible for treatment evaluation and all received CSs as a first-line therapy. Fifteen patients (47%) received methylprednisolone pulses (MPPs) at treatment initiation and 14 patients (44%) received an immunosuppressive drug (ISD), usually MTX (86%), as a second-line therapy. Complete remission was achieved for 69% of patients, remission with disability 19% and failure 12%. A poor outcome was associated with a diagnosis time delay of >6 months [odds ratio (OR) = 14.7] and the lack of MPPs (OR = 12.9). CONCLUSION: Our study reports new insights into the therapeutic management of EF: (i) CS treatment remains the standard therapy for EF, taken alone or in association with an ISD; (ii) MPPs at initiation of treatment are associated with a better outcome and a lower need of ISD use; (iii) an ISD, usually MTX, might be useful as a second-line therapy, mainly in patients with morphoea-like lesions. Naturally, these practical conclusions should be confirmed by a prospective and multicentre study.

BACKGROUND: Behçet disease (BD) is a chronic systemic inflammatory disorder of unknown etiology. OBJECTIVE: To determine the nature of T cells driving inflammatory lesions in BD. METHODS: T cell homeostasis and cytokines production were analyzed in peripheral blood and brain inflammatory lesions from 45 adult patients with BD (active and untreated BD [n = 25] and patients in remission [n = 20]) and 20 healthy donors, using Luminex, flow cytometry, immunohistochemistry, and immunofluorescence analysis. RESULTS: We found a marked increase in T(H)17 cells and a decrease in the frequency of CD4(+) forkhead box P3(+) regulatory T cells (Tregs) in peripheral blood that were induced by IL-21 production and that correlate with BD activity. The addition of serum from patients with active BD in a sorted CD4(+) T cells culture of healthy donors induced a significant and dose-dependent production of IL-17A and a decrease in forkhead box P3 expression. We demonstrated the presence of IL-21- and IL-17A-producing T cells within the cerebrospinal fluid, brain parenchyma inflammatory infiltrates, and intracerebral blood vessels from patients with active BD and central nervous system involvement. The stimulation of CD4(+) T cells with IL-21 increased T(H)17 and T(H)1 differentiation and decreased the frequency of Treg cells. Conversely, IL-21 blockade with an IL-21R-Fc restored the T(H)17 and Treg homeostasis in patients with BD. CONCLUSION: We provided here the first evidence of the critical role of IL-21 in driving inflammatory lesions in BD by promoting T(H)17 effectors and suppressing Treg cells. IL-21 represents a promising target for novel therapy in BD.

OBJECTIVE: The aim of this work was to describe chorea during systemic lupus erythematosus or antiphospholipid antibodies and its long-term outcome. METHODS: We retrospectively analyzed clinical features, laboratory findings, imaging characteristics, and outcome in a series of 32 patients. RESULTS: Most patients were women (28 of 32), and mean age at onset of chorea was 20.6 (9-62) years. Chorea was inaugural for 28 patients. Improvement was observed with various treatments. During follow-up (12.2 ± 11.3 years), severe manifestations of systemic lupus erythematosus were rare. Antiphospholipid antibodies were repeatedly positive for 90% of the patients. Twelve patients developed arterial thrombosis. Prophylactic treatment with antithrombotic therapy might reduce the risk of further thrombosis (8% versus 57%; P = 0.01). Cardiac valvulopathy occurred in 22 patients during follow-up. Chorea relapsed in 8 cases. CONCLUSIONS: Chorea had a good outcome in itself. This long-term follow-up shows, for the first time, that these patients have substantial risk for further arterial thrombosis.

Behçet's disease (BD) is a systemic variable vessel vasculitis that involves the skin, mucosa, joints, eyes, arteries, veins, nervous system and gastrointestinal system, presenting with remissions and exacerbations. It is a multifactorial disease, and several triggering factors including oral cavity infections and viruses may induce inflammatory attacks in genetically susceptible individuals. BD vasculitis involves different vessel types and sizes of the vascular tree with mixed-cellular perivascular infiltrates and is often complicated by recurrent thrombosis, particularly in the venous compartment. Several new therapeutic modalities with different mechanisms of action have been studied in patients with BD. A substantial amount of new data have been published on the management of BD, especially with biologics, over the last years. These important therapeutic advances in BD have led us to propose French recommendations for the management of Behçet's disease [Protocole National de Diagnostic et de Soins de la maladie de Behçet (PNDS)]. These recommendations are divided into two parts: (1) the diagnostic process and initial assessment; (2) the therapeutic management. Thirty key points summarize the essence of the recommendations. We highlighted the main differential diagnosis of BD according to the type of clinical involvement; the role of genetics is also discussed, and we indicate the clinical presentations that must lead to the search for a genetic cause.

OBJECTIVES: To study the pediatric presentation and evolution of relapsing polychondritis (RP), a rare inflammatory disease characterized by recurrent inflammation of cartilage. STUDY DESIGN: We retrospectively collected data from 10 patients observed in 3 French hospitals for relapsing polychondritis, with an age at onset <18 years. We also analyzed 37 cases of pediatric-onset RP from a systematic review. RESULTS: The mean age at first symptoms was 8.6 years, and the sex ratio was 6 male patients and 4 female patients. Children came to medical attention with joint pain, ocular inflammation, and chondritis. Outcomes included severe visual impairment, chronic destructive chondritis, and 1 death caused by aortic dilatation. Treatment mainly consisted of non-steroidal-anti-inflammatory drugs, corticosteroids, and immunosuppressants. Growth was normal in 7 examined patients. Systematic literature review also suggested a high number of tracheostomy in pediatric cases, but this was not confirmed in our series. CONCLUSION: RP in childhood shares the main clinical features of its adult counterpart, including destructive chondritis and systemic symptoms, but unlike adults, children frequently have a family history of autoimmunity and infrequently have other associated autoimmune diseases. RP can be fatal; close screening for complications is mandatory. Growth does not appear to be impaired by cartilage inflammation.

BACKGROUND: The neuro-ophthalmological manifestations of Behcet's disease (BD) are rare, and data regarding their characteristics and outcome are lacking. OBJECTIVE: To report prevalence, main characteristics and outcome of neuro-ophthalmological manifestations in BD. PATIENTS AND METHODS: This is a retrospective monocentric study of 217 patients diagnosed with neuro-Behçet's disease (NBD), of whom 29 (13.3%) patients presented with neuro-ophthalmological manifestations (55% of men and mean±SD age of 26±8 years). All patients underwent a detailed ophthalmological examination and were followed up in the internal medicine and the ophthalmology departments. RESULTS: Neuro-ophthalmological manifestations were the first presentation of BD in 45% of patients and developed later in the course of the disease in 55% of patients. They are divided into parenchymal (PM) and non-parenchymal (NPM)-related manifestations in, respectively, 13 patients (45%) and 16 patients (55%). PM included papillitis in seven patients (53.8%), retrobulbar optic neuritis in four patients (30.8%) and third cranial nerve palsy in two patients (15.4%). NPM included papilloedema related to cerebral venous thrombosis in all 16 patients, of whom 6 patients (37.5%) had sixth cranial nerve palsy. At initial examination, 93.1% of patients had visual alterations, including mainly decreased visual acuity visual field defects and/or diplopia. All patients were treated with corticosteroids and 79% of patients received immunosuppressive agents. After treatment, the visual outcome improved or stabilised in 66.7% of patients while it worsened in 33.3. The mean±SD logarithm of the minimum angle of resolution visual acuity improved from 0.4±0.3 at diagnosis to 0.2±0.3 after therapy. 10.3% and 3.4% of patients were legally blind at diagnosis and after therapy, respectively. CONCLUSION: Neuro-ophthalmological manifestations of BD represented 13% of NBD. They could be potentially severe and disabling. Prompt treatment is the key factor in improving visual outcome.

OBJECTIVE: Arterial aneurysms are characteristic of medium-size vessel vasculitis but are a very unusual feature of Wegener's granulomatosis (WG). We describe a typical WG case, complicated by arterial aneurysms and review previously reported cases. METHODS: Medline database search of cases published between January 1978 and July 2006, in English, reporting arterial aneurysms complicating WG. RESULTS: Five years after diagnosis, a 29-year-old man with typical WG developed macro- and microaneurysms located on branches of the hepatic and renal arteries during a disease relapse. The main symptoms were abdominal pain, vomiting, and altered general status. He was successfully treated by coil embolization in combination with prednisone, intravenous mycophenolate mofetil, and high-dose immunoglobulins. Twelve additional cases of WG complicated by arterial aneurysms are reported in the English literature. This represents a life-threatening complication since rupture occurred in half of the patients. CONCLUSIONS: Although small-vessel injury predominates in WG, inflammation of medium-size arteries may occur and lead to aneurysm formation. Abdominal angiography should be recommended when unexplained abdominal pain occurs during a WG flare.

CONTEXT: Erdheim-Chester disease (ECD) is a rare non-Langerhans form of histiocytosis characterized by xanthomatous tissue infiltration with CD68(+) CD1a(-) foamy histiocytes. Endocrine problems, such as diabetes insipidus and hypogonadotropic hypogonadism, frequently occur in ECD, but bilateral adrenal infiltration has rarely been reported in this disease. OBJECTIVE: The aim of the study was to describe adrenal and periadrenal infiltration in ECD. PATIENTS: A total of 22 patients with ECD undergoing systematic computed tomography to search for signs of adrenal enlargement participated in the study. RESULTS: Of the 22 patients with ECD, seven (31.8%) displayed adrenal infiltration on computed tomography. In one case, autopsy confirmed that the adrenal enlargement was due to foamy histiocyte infiltration in the adrenal glands. Possible adrenal insufficiency was assessed in five of the seven patients. One developed signs of adrenal insufficiency, which was confirmed by adrenocorticotropin stimulation tests. Adrenal involvement was reported in only 15 of the 240 ECD cases published up to May 2006. This frequency is significantly lower than that in our series (P = 0.0008; Fisher's exact test). CONCLUSION: Physicians should be aware of ECD as a possible cause of morphological changes in adrenal size and infiltration.

Aseptic abscesses (AA) are characterized by deep, sterile, round lesions consisting of neutrophil that do not respond to antibiotics but improve dramatically with corticosteroids. We report the clinical, laboratory, and radiologic characteristics and the associated conditions of 29 patients from the French Register on AA plus 1 patient from the Netherlands.The mean age of patients at AA diagnosis was 29 years (SD = 14). The main clinical manifestations of AA were fever (90%), abdominal pain (67%), and weight loss (50%). Duration of symptoms was 4.7 months on average until abscesses were discovered. The abscesses involved the spleen in 27/29 patients (93%; the thirtieth patient had a personal history of splenectomy after a trauma). In 7 they were unifocal and in the others they were multifocal, involving in addition the abdominal lymph nodes in 14 (48%), liver in 12 (40%), lung in 5 (17%), pancreas in 2 (7%), and brain in 2 (7%). They were not splenic in 3, including 2 with abdominal lymph nodes and 1 with superficial lymph nodes and testicle and lung involvement. Twenty-two patients (70%) had elevated white blood cell and neutrophil count; antineutrophil cytoplasmic autoantibodies with a perinuclear, cytoplasmic or atypical pattern (negative for antiproteinase 3 and negative for antimyeloperoxidase except for 1) were positive in 21% of the 24 patients tested. Twenty-one patients had inflammatory bowel disease (IBD), which preceded the occurrence of abscesses in 7, was concomitant in 7, and appeared secondarily in 7. Six patients had neutrophilic dermatosis (20%), 3 had relapsing polychondritis as an associated condition, and 3 others had monoclonal gammopathy of undetermined significance. Three patients had no associated condition. Splenectomy was performed in 15 (52%) patients. All patients received steroid therapy. Thirteen (43%) were given additional immunosuppressive therapy, 1 immediately and the others after a relapse, of whom 3 were also treated by anti-tumor necrosis factor-alpha agents. Mean follow-up was 7 years. Eighteen (60%) patients experienced 1 or several relapses, but there was no death related to AA. Relapses occurred on immunosuppressive therapy in 2 patients and off immunosuppressive therapy in the others while corticosteroids were being tapered. We surveyed the literature and analyzed 19 additional cases. AA is an emergent and probably underrecognized entity. It represents an apparently noninfectious inflammatory disorder involving neutrophils that responds to corticosteroid therapy. AA mainly affects patients with IBD but also affects those with other conditions, or with no other apparent disease.

AIM: Severe uveitis is potentially associated with visual impairment or blindness in young patients. Therapeutic strategies remain controversial. The efficacy of interferon alpha-2a (IFN-alpha2a) in severe uveitis, refractory to steroids and conventional immunosuppressive agents, was evaluated. PATIENTS AND METHODS: Patients were included after a major relapse of uveitis following corticosteroids and immunosuppressants. IFN-alpha2a (3 million units three times a week) was administered subcutaneously. Efficacy was assessed by improvement in visual acuity, decrease in vitreous haze, resolution of retinal vasculitis and macular oedema, assessed by fundus examination and fluorescein angiography, and decrease in oral prednisone threshold. RESULTS: 45 patients were included. Median age was 32.3 years (range 8-58) and sex ratio (F/M) was 0.66. Uveitis was associated with Behçet's disease in 23 cases (51.1%) and with other entities in 22 cases (48.9%). Median duration of uveitis before interferon therapy was 34.9 months (range 3.4-168.7) and an average of 3.26 relapses following corticosteroids and immunosuppressants was noted. Uveitis was controlled in 82.6% of patients with Behçet's disease and 59% of patients with other types of uveitis (p = 0.07). During a mean follow-up of 29.6 months (range 14-55), median oral prednisone threshold decreased significantly from 23.6 mg/day (range 16-45) to 10 mg/d (range 4-14) (p<0.001). Interferon was discontinued in 10 patients (22.2%) with Behçet's disease and in four patients without Behçet's disease. Relapses occurred in four and one cases, respectively. CONCLUSIONS: Interferon therapy appears to be an efficient strategy in severe and relapsing forms of Behçet's disease but also in other uveitic entities. However, it seems to act more to suspend rather than cure the disease. Therefore, IFN-alpha2a may be proposed as a secondline strategy after failure of conventional immunosuppressants.

The antimalarial agents, chloroquine (CQ) and hydroxychloroquine (HCQ) are used in long-term treatment of connective tissue diseases and dermatological disorders and are generally regarded as safe. We present one case of cardiotoxicity in a 59-year-old woman treated with antimalarials during 13 years for a discoid lupus erythematosus. She progressively developed conduction disturbances and congestive heart failure (CHF). When the diagnosis of antimalarials toxicity was suspected, CQ was withdrawn. However, heart transplantation had to be performed in the following 4 months for severe CHF. Indeed, rare but severe cardiotoxicity may develop following prolonged use of antimalarials with both conduction disturbances (45 patients) and CHF (25 patients). These cardiac toxic effects have been reported with CQ and less frequently with HCQ use alone. Diagnoses are often delayed since the toxicity of the drug might be misattributed to other factors in these patients. The endomyocardial biopsy, or in some cases the muscle biopsy, are essential to confirm the antimalarials toxicity. Antimalarials have been stopped in 12 cases of CHF, leading to improvement in 8 cases (within 3 months to 5 years) and to deaths or to heart transplantation in 4 cases (within 1 week to 3 months). In the latter cases, as in our patient, the lack of improvement may have been explained by the severity of the cardiomyopathy at diagnosis and the short delay since withdrawal. As a consequence, the potential for reversibility and the severity in undiagnosed cases of these toxic cardiomyopathies emphasize the importance of recognizing early signs of toxicity in order to withdraw antimalarials before the occurrence of life-threatening CHF.

Erdheim-Chester disease is a non-Langerhans cell histiocytosis, classically thought to be rare, but diagnosed more frequently nowadays (250 published cases). Histiocytes of Erdheim-Chester disease are positive for CD68 but not for CD1a, contrary to Langerhans cell histiocytosis. Two signs highly evocative of this diagnosis are nearly constant tracer uptake by the long bones on (99)Tc bone scintigraphy and a "hairy kidney" appearance on abdominal CT scan. A more "elegant" diagnostic method is ultrasound-guided biopsy of the perirenal infiltration. Cardiovascular involvement, which affects the aorta ("coated aorta") as well as all the cardiac layers, leads to one third of the deaths related to this disease. Central nervous system infiltration (especially cerebellar) is severe and difficult to treat. The prognosis is extremely variable and is often worse when there is a cardiovascular and/or central nervous system involvement. The treatment, decided upon on a case-by-case basis at a specialist center, often begins with interferon alpha.

OBJECTIVE: To compile and assess data about complication and success rates for in vitro fertilization (IVF) of women with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). To date, such data are sparse. METHODS: This retrospective study described women with SLE and/or APS who have had at least 1 IVF cycle. RESULTS: Thirty-seven women with SLE (n = 23, including 8 with antiphospholipid antibodies), SLE with APS (n = 4), or primary APS (n = 10) underwent 97 IVF procedures. For 43% of cases, the infertility was female in origin, for 19% male, 14% mixed, and 24% unexplained. No women had premature ovarian insufficiency because of cyclophosphamide. Median age at IVF was 34 years (range 26-46). The median number of IVF cycles was 2.6 (1-8). Patients were treated with hydroxychloroquine (72%), steroids (70%), azathioprine (3%), aspirin (92%), and/or low molecular weight heparin (62%). There were 27 (28%) pregnancies, 23 live births among 26 neonates (3 twin pregnancies), 2 miscarriages, and 2 terminations for trisomy 13 and 21. Six spontaneous pregnancies occurred during the followup. Finally, 26 women (70%) delivered at least 1 healthy child. Complications occurred in or after 8 IVF cycles (8%): SLE flares in 4 (polyarthritis in 3 and lupus enteritis in 1) and thromboembolic events in 4 others. One SLE flare was the first sign of previously undiagnosed SLE. Poor treatment adherence was obvious in 2 other flares and 2 thromboses. No ovarian hyperstimulation syndrome was reported. CONCLUSION: These preliminary results confirm that IVF can be safely and successfully performed in women with SLE and/or APS.

We postulated that high-dose chemotherapy (HDC) followed by peripheral autologous hematopoietic stem cell transplantation might help to control refractory central nervous system (CNS) histiocytic disorders. Six patients with histiocytic CNS involvement were treated in this way. Two patients achieved non-active disease status, although one relapsed at 84 months. Two patients had regressive disease, one of whom progressed at 21 months. One patient had progressive disease at 14 months. One patient had extra-CNS progression but CNS regression. After a median follow-up of 22.4 months, only one of the six patients still has non-active disease. Treatment was effective on craniofacial and space-occupying brainstem lesions, and was ineffective on neurodegenerative lesions.

Dermatomyositis and polymyositis patients have an increased risk of developing cancers. We have assessed the diagnostic values of serum tumor markers for the detection of solid cancer in dermatomyositis/polymyositis patients. Serum carcinoembryonic antigen, CA15-3, CA19-9, and CA125 were assayed by immunoradiometric methods in 102 dermatomyositis/polymyositis patients. All the patients had complete physical examination, chest X-ray, echocardiogram, gastrointestinal tract endoscopic explorations, thoracoabdomino-pelvic computed tomography scan, and all women had gynecologic examination and mammogram. Exclusion criteria for study were childhood dermatomyositis, inclusion body myositis, myositis associated with a connective tissue disease, prior history of cancer, and the presence of benign conditions known to elevate serum tumor markers. After a median follow-up of 59 months, 10 (9.8%) patients had a solid cancer. Initial elevation of CA125 was associated with an increased risk of developing solid cancer [P = 0.0001 by Fisher's exact test; odds ratio (OR), 29.7; 95% confidence interval (95% CI), 8.2-106.6]. For CA19-9, there was a trend towards a significant association (P = 00.7; OR, 4.5; 95% CI, 1-18.7, respectively). Diagnostic values of elevated CA125 and CA19-9 at screening increased when the study analysis was restricted to patients who developed a cancer within 1 year (P < 0.0001 and P = 0.018, respectively) or to patients without interstitial lung disease (P = 0.00001; OR, 133; 95% CI, 6.5-2733 and P = 0.027; OR, 9; 95% CI, 1.5-53, respectively). Individual comparisons of the baseline and the second CA125 value showed that three of the eight patients with cancers versus 3 of the 76 patients without, displayed an increase of their CA125 level (P = 0.01 by Fisher's exact test). We conclude that CA125 and CA19-9 assessment could be useful markers of the risk of developing tumors for patients with dermatomyositis and polymyositis and should therefore be included in the search for cancer in dermatomyositis/polymyositis patients, especially for patients without interstitial lung disease.
