Medication and the patient-doctor relationship: a qualitative study with patients suffering from fibromyalgia.

BACKGROUND: Fibromyalgia is characterized by a diffuse and predominantly axial and chronic pain, for which there is no explicit rationale for treatment options. OBJECTIVE: This qualitative study aims to understand the medication experience of patients with fibromyalgia and their relationship with the doctors derived from treatment negotiation. DESIGN: A qualitative approach was used, based on interviews with patients. SETTING AND PARTICIPANTS: Semi-structured interviews were held in a public hospital, with 35 patients diagnosed with fibromyalgia. Qualitative content analysis was performed. RESULTS: The first axis is centred on the unsuccessful quest for an effective treatment for pain and the feeling of dismissal of patients, who are in search of validation and recognition. The second part of the accounts explains the medication adjustments and the search for collaboration. Developing a model of partnership with the doctor enables the patients to shape their own illness, through the medication. DISCUSSION: It is by mediating their relationship with medication that patients gain access to this state of co-expertise and that they put sense into the collaboration they develop with their doctors. Through this collaboration, useful drugs are identified and adjusted to treat the pain.

Echocardiographic evidence for valvular toxicity of benfluorex: a double-blind randomised trial in patients with type 2 diabetes mellitus.

OBJECTIVES: REGULATE trial was designed to compare the efficacy and safety of benfluorex versus pioglitazone in type 2 diabetes mellitus (DM) patients. METHODS: Double-blind, parallel-group, international, randomised, non-inferiority trial. More than half of the 196 participating centres were primary care centres. Patients eligible had type 2 DM uncontrolled on sulfonylurea. 846 were randomised. They received study treatment for 1 year. 423 patients were allocated to benfluorex (150 to 450 mg/day) and 423 were allocated to pioglitazone (30 to 45 mg/day). Primary efficacy criterion was HbA(1c). Safety assessment included blinded echocardiographic evaluation of cardiac and valvular status. RESULTS: At baseline, patients were 59.1 ± 10.5 years old with HbA1c 8.3 ± 0.8%, and DM duration 7.1 ± 6.0 years. During the study, mean HbA1c significantly decreased in both groups (benfluorex: from 8.30 ± 0.80 to 7.77 ± 1.31 versus pioglitazone: from 8.30 ± 0.80 to 7.45 ± 1.30%). The last HbA1c value was significantly lower with pioglitazone than with benfluorex (p<0.001) and non-inferiority of benfluorex was not confirmed (p = 0.19). Among the 615 patients with assessable paired echocardiography (310 benfluorex, 305 pioglitazone), 314 (51%) had at least one morphological valvular abnormality and 515 (84%) at least one functional valvular abnormality at baseline. Emergent morphological abnormalities occurred in 8 patients with benfluorex versus 4 with pioglitazone (OR 1.99), 95% CI (0.59 to 6.69). Emergent regurgitation (new or increased by one grade or more) occurred more frequently with benfluorex (82 patients, 27%) than with pioglitazone (33 patients, 11%) (OR 2.97), 95% CI (1.91 to 4.63) and were mainly rated grade 1; grade 2 (mild) was detected in 2 patients with benfluorex and 3 with pioglitazone. There was no moderate or severe regurgitation. CONCLUSION: After 1 year of exposure, our results show a 2.97 fold increase in the incidence of valvular regurgitation with benfluorex and provide evidence for the valvular toxicity of this drug.

IgG4-related systemic disease: features and treatment response in a French cohort: results of a multicenter registry.

IgG4-related systemic disease is now recognized as a systemic disease that may affect various organs. The diagnosis is usually made in patients who present with elevated IgG4 in serum and tissue infiltration of diseased organs by numerous IgG4+ plasma cells, in the absence of validated diagnosis criteria. We report the clinical, laboratory, and histologic characteristics of 25 patients from a French nationwide cohort. We also report the treatment outcome and show that despite the efficacy of corticosteroids, a second-line treatment is frequently necessary. The clinical findings in our patients are not different from the results of previous reports from Eastern countries. Our laboratory and histologic findings, however, suggest, at least in some patients, a more broad polyclonal B cell activation than the skewed IgG4 switch previously reported. These observations strongly suggest the implication of a T-cell dependent B-cell polyclonal activation in IgG4-related systemic disease, probably at least in part under the control of T helper follicular cells.

Dysferlin deficiency treated like refractory polymyositis.

When an adult suffers from muscular symptoms, the diagnosis of polymyositis is often accepted if muscular biopsy reveals necrosis, fibrosis and cellular infiltrate with high expression of major histocompatibility complex class I. Late-onset limb-girdle muscular dystrophy (LGMD) can also be considered. We report the case of a young woman who suffers from dysferlin deficiency, and who was mistakenly treated for refractory polymyositis for 5 years. In LGMD, standard pathological analysis can indeed wrongly give a diagnosis of polymyositis. Immunofixation must be performed to avoid this mistake.

Yield of bone marrow examination in diagnosing the source of fever of unknown origin.

BACKGROUND: Fever of unknown origin (FUO) still remains a diagnostic challenge, while diagnosis may remain obscure for several weeks or months. The role of tissue biopsy is crucial in the diagnostic approach. We report a series of 130 consecutive patients with FUO who had undergone a bone marrow biopsy (BMB). METHODS: Among 280 consecutive nonimmunocompromised patients hospitalized between 1995 and 2005 for a febrile illness of uncertain cause, lasting at least 3 weeks, with no diagnosis after an appropriate minimal diagnostic workup, 130 underwent BMB. RESULTS: Overall, a specific diagnosis was achieved by BMB and histological examination in 31 cases (diagnostic yield, 23.7%). Three types of diseases were found: hematological malignant diseases in 25 cases, including 19 patients with malignant lymphoma, 4 with acute leukemia, 1 with hairy cell leukemia, and 1 with multiple myeloma; infectious diseases in 3 cases; systemic mastocytosis in 2 cases; and disseminated granulomatosis in 1 case. Thrombocytopenia (odds ratio, 4.9; 95% confidence interval, 1.04-9.30) and anemia (odds ratio, 3.24; 95% CI, 1.13-9.34) were the most reliable predictive factors regarding the usefulness of BMB. Bone marrow cultures had very limited value in our cohort. Finally, corticosteroid use did not seem to affect the yield of BMB. CONCLUSIONS: Bone marrow biopsy is a useful technique for the diagnosis of prolonged fever in immunocompetent patients. Thrombocytopenia and anemia seem to be correlated with the value of this test.

Recurrent cerebral venous thrombosis revealing paraneoplastic angiitis in Hodgkin's lymphoma.

Recurrent cerebral venous thrombosis (CVT), as a manifestation of paraneoplastic angiitis and revealing of nodular lymphocyte predominant Hodgkin's disease (NLPHD), is an extremely rare condition. We herein report a 55-year-old man who developed recurrent CVT despite efficacious anticoagulant therapy and subsequent stenting of the superior longitudinal sinus. Progressive neurological deterioration ensued and a body scan revealed axillary lymph nodes. Pathological analysis led to a diagnosis of NLPHD. Conventional angiography showed CVT and multiple arterial narrowings. A paraneoplastic primary cerebral angiitis with prominent venous structure involvement was suspected. Immunotherapy using rituximab and steroids provided a dramatic recovery. This case of CVT due to paraneoplastic cerebral angiitis is a rare condition and represents a new, very rare manifestation of nodular lymphocyte predominant Hodgkin's disease.

[Management of cancer-related fatigue]. / Prise en charge de l'asthénie associée au cancer.

INTRODUCTION: Cancer-related fatigue is very common but its management remains frustrating. We thus sought to review current knowledge in this field: epidemiologic data, pathophysiological mechanisms, assessment, and treatment. METHODS: We queried the Medline database for all articles on this topic published between 1997 and 2007 and analyzed the articles published in English and French, as well as some of the essential earlier work. RESULTS: Approximately 60 to 96% of patients treated for cancer report fatigue. The prevalence of fatigue that persists after the disease is considered to be in remission is substantial. Fatigue is a multidimensional problem with biological, psychological, social, and personal aspects. Physical causes must be systematically considered (comorbidities, anemia, and endocrine disorders), but most cases remain unresolved. Many may be attributed to deconditioning. There is not now any pharmacological therapy that treats this symptom effectively. Some psychostimulants are being tested, but the initial results of the studies are contradictory. Exercise is the intervention for which there is the most evidence of effectiveness. CONCLUSION: Cancer-related fatigue is a very common symptom for which no specific cause can usually be identified. In this situation, rest may be more harmful than exercise.

Angioimmunoblastic T-cell lymphoma: clinical and laboratory features at diagnosis in 77 patients.

We retrospectively analyzed 77 patients with pathologically diagnosed angioimmunoblastic T-cell lymphoma from a single city. There were 43 men and 34 women; the median age was 64.5 years (range, 30-91 yr). Average time between first symptoms of the disease and diagnosis was 3.6 months. At diagnosis, peripheral nodes were present in all but 1 patient, and were generalized in 90% of cases. Constitutional symptoms were reported in 77% of cases and spleen enlargement in 51%. A cutaneous eruption--morbilliform, urticarial, or more polymorphic--was present in 45% of patients; in one-third of them, the eruption occurred after drug administration. Other clinical manifestations included pleuritis (22%); arthralgia or arthritis (17%); ear, nose, and throat involvement (14%); central or peripheral neurologic manifestations (10%); and ascites (5%). Most patients presented with advanced disease at diagnosis (bone marrow involvement in 60% of cases). The main laboratory abnormalities were elevated lactate dehydrogenase levels (71%), inflammatory syndrome (67%), hypergammaglobulinemia (50%), anemia (51%), and lymphopenia (52%). Auto- or disimmune manifestations were reported in one-third of patients: autoimmune hemolytic anemia was present at diagnosis in 19% of patients and thrombocytopenic purpura in 7%. Documented vasculitis was described in 12% of cases. Clonality was analyzed in lymph nodes in 47 patients: T-cell and B-cell clones were found in 45 (96%) and 20 (45%) patients, respectively. Chromosomal abnormalities were identified in 62% of cases: trisomies 3, 5, 18, 19, additional X chromosome, and deletion of chromosome 7 were the most common abnormalities. The current study underlines the diversity of presenting manifestations of angioimmunoblastic T-cell lymphoma.

Clinical significance of anti-histidyl-tRNA synthetase (Jo1) autoantibodies.

The clinical significance of a discovery of anti-histidyl-tRNA synthetase (Jo1) autoantibodies patients was established in the early diagnosis of antisynthetase syndrome (ASS) as the common form of this pathology is characterized by interstitial lung disease (ILD), inflammatory muscle disease, and production of anti-Jo1 autoantibodies. However, the specificity of such autoantibodies has to be evaluated in daily clinical practice. In this study, the clinical and prognostic profiles of 45 patients displaying anti-Jo1 autoantibodies were determined. Among 36 patients with a titer of anti-Jo1 autoantibodies above the cutoff value suggested by the manufacturer (40 AU/mL), three different groups were identified. The first group (n = 26) suffered from a complete or incomplete ASS and showed anti-Jo1 autoantibodies mostly above 60 AU/mL. A second group (n = 7) suffered from another autoimmune disease, that is, a systemic lupus erythematosus, cutaneous lupus and rheumatoid arthritis, and Crohn's disease with anti-Jo1 autoantibodies mostly below 60 AU/mL. The third group (n = 3) did not suffer from any autoimmune disease and presented anti-Jo1 autoantibodies below 60 AU/mL. The nine doubtful cases (titer of anti-Jo1 autoantibodies of 30-39 AU/mL) were from patients with no ASS nor myositis. Only 27 out of 45 patients showed antinuclear antibodies with 15 sera showing a pattern characteristic of anti-Jo1 autoantibodies by indirect immunofluorescence on HEp2 cells. In conclusion, this study underlines the need to search for anti-Jo1 autoantibodies even if antinuclear antibodies are negative by indirect immunofluorescence and underlines the usefulness of anti-Jo1 antibodies of titer above 60 AU/mL in the diagnosis of complete or incomplete ASS.

Aseptic abscesses: a study of 30 patients with or without inflammatory bowel disease and review of the literature.

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.

Neurological manifestations and neuroradiological presentation of Erdheim-Chester disease: report of 6 cases and systematic review of the literature.

Erdheim-Chester disease (ECD) is a rare, non-Langerhans form of histiocytosis of unknown etiology that affects multiple organs. We report 6 cases of ECD with neurological involvement and neuroradiological abnormalities on brain MRI. A literature review revealed 60 other cases of ECD with neurological involvement. We therefore analyzed 66 ECD patients with neurological involvement. Cerebellar and pyramidal syndromes were the most frequent clinical manifestations (41% and 45% of cases), but seizures, headaches, neuropsychiatric or cognitive troubles, sensory disturbances, cranial nerve paralysis or asymptomatic lesions were also reported. Neurological manifestations were always associated with other organ involvement, especially of bones (at least 86%) and diabetes insipidus (47%). Neurological involvement was responsible for severe functional handicaps in almost all patients and was responsible for the death of 6 of the 66 patients (9%). Neuroradiological findings could be separated into three patterns: the infiltrative pattern (44%), with widespread lesions, nodules or intracerebral masses, the meningeal pattern (37%), with either thickening of the dura mater or meningioma-like tumors, and the composite pattern (19%), with both infiltrative and meningeal lesions.

Systemic mastocytosis: predictable factors of poor prognosis present at the onset of the disease.

Systemic mastocytosis (SM) refers to a group of heterogeneous diseases that can be divided into indolent SM, for which prognosis is favorable, and malignant SM, which has a poor prognosis. While the diagnosis of SM is often a challenge since clinical and biological abnormalities are not specific, prognosis is even more difficult to predict. Thus, we aimed to highlight predictable factors in a cohort of 28 cases of SM. Among the 13 women and 15 men studied were 7 patients who had an aggressive form of SM that ultimately led to death in 3 of them. We found common characteristics among these seven patients. First, they were older when the first symptoms appeared and when the diagnosis was confirmed. Second, ascitis, lymphadenopathy, anemia, and thrombocytopenia were significantly more frequent, while cutaneous lesions and flush were less frequent. Moreover, general symptoms, gastrointestinal disorders, neutropenia, and coagulation abnormalities also seemed to characterize this group of patients. Understanding the factors that predict SM is essential in order to provide patients with the malignant form of the disease with specific treatments.

Lupus-like presentation of parvovirus B19 infection.

OBJECTIVES: To describe 2 cases of parvovirus B19 (B19) infection mimicking systemic lupus erythematosus (SLE) and to identify all cases of SLE imitated by and/or associated with B19 in the medical literature. METHODS: A computer-assisted (PubMed) search of the medical literature from 1975 to 2003 was performed using the following key words: parvovirus, B19, SLE, lupus, antibodies, auto-immunity. RESULTS: Thirty-eight patients were identified: 35 women, 3 men; mean age = 28.8 years. Clinical manifestations were as follows: fever (24 patients); articular involvement (36 patients); cutaneous lesions (28 patients); lymphadenopathy (9 patients); hepato- and/or splenomegaly (6 patients); serositis (6 patients); renal involvement (4 patients); cerebral impairment (10 patients). Cytopenia was observed in 23 cases. Antinuclear antibodies were detected in 34 patients, anti-double-stranded DNA antibodies in 20 patients, anti-Sm antibodies in 4 patients, antinuclear ribonucleoprotein antibodies in 5 patients, anti-Ro-SSA antibodies in 4 patients, anti-La-SSB antibodies in 4 patients, and anticardiolipin and/or anti-beta2-glycoprotein I antibodies in 8 patients. Hypocomplementemia was found in 15 of 26 patients. In 19 cases, the B19 infection had a self-limiting course. In 6 cases, B19 infection occurred in a context of previously established SLE, simulating SLE exacerbation. In 6 observations, symptoms persisted several months after the viral infection. In 7 cases, the exact relationship between SLE and B19 could not be determined. CONCLUSIONS: B19 infection may present a clinical and serological tableau making it difficult to distinguish between a viral infection and the first episode of SLE. Although B19 may modulate the clinical and biological features of rheumatic disease, studies in large series do not support a causative role for B19 in the pathogenesis of SLE.

Prevalence and pattern of antinuclear autoantibodies in 347 patients with non-Hodgkin's lymphoma.

The presence of antinuclear autoantibodies (ANA) was investigated in a large cohort of patients with non-Hodgkin's lymphoma (NHL) in order to assess their frequency, specificity and prognostic relevance. ANA were analysed in 347 patients with different histological subgroups of NHL and in 213 controls using an indirect immunofluorescence technique on HEp2 cells. As the appearance of autoantibodies may be found after treatment of NHL, samples were collected at the time of diagnosis of NHL before any therapy. Sixty-six (19%) NHL patients and 12 (5.6%) patients from the control group displayed ANA. The prevalence between the two groups was found to be significantly higher in NHL patients (P < 0.0001) with a marked increased prevalence in follicular and mantle cell lymphoma subgroups. Autoantibodies directed against mitotic proteins or mitotic-associated proteins were found in 6.9% of NHL patients versus 0.5% in the control group (P < 0.001), with a significantly increased incidence in follicular and mantle cell lymphoma subgroups (P < 0.0001). Some 28% of the patients with positive ANA displayed clinical symptoms that could correspond to classical autoimmune manifestations, this frequency appearing to be higher in the marginal zone/mucosa-associated lymphoid tissue lymphoma subgroup. These data demonstrate a significant incidence of ANA before any treatment in NHL occurrence, which seems to be higher in some histological subgroups with particular ANA, such as ANA directed against mitotic proteins or mitotic-associated proteins.

[Acquired angioneurotic edema induced by hormonal contraception]. / Oedème angio-neurotique acquis induit par la contraception hormonale.

OBJECTIVE: Although frequently pointed out in the aetiology of chronic angioedema or chronic abdominal pain, food allergy is frequently a diagnosis for lack of anything better, as exemplified by disappointing results of eviction regimens. This has resulted in the search for other aetiologies, such as an iatrogenic effect of oral contraceptives. METHODS: Detailed medical history was obtained on 38 young women, aged a mean of 26 years, experiencing chronic angioedema initially ascribed to food hypersensitivity, but in whom a deficit in C1 inhibitor was demonstrated. We investigated the effects of oral contraception on their level of C1-INH, functional C1-INH assay and their clinical symptoms. RESULTS: An interruption of oral contraception induced an increase of the C1-INH level from 0.201 to 0.224 g/L (p < 0.002) and of the C1-INH functional assay fom 0.396 to 0.702 U (p < 0.0001), associated with a recovery or a marked improvement of the clinical symptoms formerly ascribed to food allergy. The replacement of the initial contraception containing ethinyloestradiol by a progestogen maintained or even improved their clinical and biological state. CONCLUSION: Exogenous estrogen such as those contained in most oral contraceptive may play an iatrogenic role in the aetiology of chronic angioedema.

Exogenous oestrogen as an alternative to food allergy in the aetiology of angioneurotic oedema.

Although frequently reported as an aetiology for chronic angioneurotic oedema or urticaria, food allergy is often a diagnosis proposed in the absence of more convincing evidence, as illustrated by the disappointing results of eviction regimens. We report a series of women with an initial diagnosis of food allergy, but in whom the role of oral contraceptives was subsequently demonstrated. Detailed medical history was obtained from 26 young women presenting with chronic angioneurotic oedema or urticaria initially attributed to food allergy, but in whom C1-esterase inhibitor (C1 INH) deficiency was demonstrated. We investigated the effects of oral contraception on C1 INH levels, C1 INH activity and clinical symptoms of these patients. Discontinuation of oral contraception induced an increase in C1 INH levels and C1 INH activity, associated with recovery or marked improvement of the clinical symptoms formerly attributed to food allergy. The relatively high frequency of women taking cyproterone acetate in this population appeared to be a remarkable finding. Replacement of the initial contraception containing ethinylestradiol by a progestogen maintained or even accentuated these good therapeutic results. Exogenous oestrogens, such as those contained in most oral contraceptives, may play an iatrogenic role in the aetiology of chronic angioneurotic oedema or urticaria.

Neurologic presentation of Whipple disease: report of 12 cases and review of the literature.

We report 12 cases of Whipple disease in patients with prominent neurologic symptoms, along with 122 cases of Whipple disease with nervous system involvement reported in the literature. We analyzed the clinical signs and results of additional examinations in 2 groups: the first group included patients with predominantly but not exclusively neurologic signs, and the second included patients with clinically isolated neurologic presentation of the disease. Whipple disease is a multisystemic infectious disease due to Tropheryma whippelii that may present with prominent or isolated symptoms of either the central or the peripheral nervous system. Recent reports stress the importance of polymerase chain reaction (PCR) analysis of cerebrospinal fluid, magnetic resonance imaging (MRI) during follow-up, and prolonged antibiotic therapy with drugs able to cross the blood-brain barrier. Cerebrospinal fluid should be analyzed repeatedly during follow-up, and treatment should be discontinued only when the results of PCR assay performed on cerebrospinal fluid are negative. Other examinations to be done include searching for gastrointestinal tract involvement with multiple duodenal biopsies and searching for systemic involvement with lymph node biopsies, which should be analyzed with light microscopy, electron microscopy, and PCR. When all examinations are negative, if Whipple disease is suspected and a lesion is found on brain MRI, a stereotactic cerebral biopsy should be performed. Treating Whipple disease with long-term trimethoprim-sulfamethoxazole is usually effective, but the use of third-generation cephalosporins in case of incomplete response deserves further attention.
