Adult-onset still disease: manifestations, treatment, outcome, and prognostic factors in 57 patients

We conducted a retrospective observational study to describe a cohort and identify the prognostic factors in adult-onset Still disease (AOSD). Patients enrolled in this retrospective chart review fulfilled either Yamaguchi or Fautrel criteria. Candidate variables were analyzed with logistic unadjusted and adjusted regression models. Fifty-seven patients were seen in the internal medicine (75%) and rheumatology (25%) departments over a mean period of 8.4 years. The median time to diagnosis was 4 months. The course of AOSD was monocyclic in 17 patients, polycyclic in 25, and chronic in 15. The assessment of glycosylated ferritin (GF) in 37 patients was correlated with early diagnosis. Nine F-fluorodeoxyglucose positron emission tomography (FDG-PET) scans identified the lymph nodes and glands as the main sites of hypermetabolism. Complications were frequent (n = 19), including reactive hemophagocytic syndrome (n = 8). None of the 3 deaths could be attributed to AOSD. Corticosteroid dependence, as predicted by a low GF level, occurred in 23 patients (45%). A quarter of the patients received tumor necrosis factor-α blockers or anakinra with good tolerance. Fever >39.5 °C was predictive of monocyclic AOSD, while arthritis and thrombocytopenia were associated with chronic and complicated AOSD, respectively. The youngest patients had the highest risks of resistance to first-line treatments.AOSD remains difficult to diagnose. Mortality is low despite frequent complications. GF and FDG-PET scans were of value in the diagnostic approach. The condition in highly symptomatic patients evolved to systemic AOSD, whereas more progressive patterns with arthritis predicted chronic AOSD.

[Autoimmune diseases and cancers. Part I: cancers complicating autoimmune diseases and their treatment]

The link between systemic disease and cancer is not fortuitous. An autoimmune disease can represent the starter for developing a non-Hodgkin lymphoma. This is particularly true for Sjögren's syndrome that is associated with the highest risk of lymphoma (odds ratio up to 44). Other systemic autoimmune diseases concerned are systemic lupus with an odds ratio of 4.5 and rheumatoid arthritis with an odds ratio of 2 to 3. It is now well established that high inflammatory activity, rather than immunosuppressive treatment, is the major risk determinant. The association between solid cancer and autoimmune systemic disease is uncommon and concerns in particular scleroderma and lung cancer. Concerning biotherapy-induced cancers, there is no demonstrated increased risk with anti-TNFα (except for cutaneous carcinoma and maybe melanoma) or with tocilizumab and abatacept even if studies with longer follow-up are needed at least for these two last drugs.

[Is a patient's knowledge of cardiovascular risk factors better after the occurrence of a major ischemic event? Survey of 135 cases and 260 controls]

AIM

We hypothezised that patients (cases) who are hospitalized for a major ischemic event--myocardial infarction, stroke, decompensation of peripheral arterial disease--acquire better knowledge than a control population--atheromatous patients without a major ischemic event, patients consulting for a vein disease or a diabetes evaluation, and accompanists--about cardiovascular risk factors (smoking, hypertension, diabetes, dyslipidemia, obesity) and have a better understanding of the usefulness of making changes in their lifestyle (quit smoking, regular exercise, Mediterranean diet, low salt diet, weight control, diabetes care).

METHODS

A questionnaire was proposed at vascular surgery consultations and vascular and cardiac functional explorations, at the M Pavillon of the Édouard-Herriot hospital, Lyon, France. In five months, 395 questionnaires (135 cases and 260 controls) were analyzed.

RESULTS

The global knowledge score was statistically higher for cases than for controls (cases 3.23±1.81; controls 2.77±2.03; P=0.037). Cases did not abide by monitoring and dietary rules better, except as regards the management of diabetes. Regular physical activity was statistically more prevalent among controls than among cases. Cases mainly received their information from their doctors (general practitioner for 59% of controls and 78% of cases, cardiologist for 25% of controls and 57% of cases) while controls got their information more through magazines or advertising.

CONCLUSION

Our results show that after a major ischemic event, cases' knowledge of risk factors is better than the rest of the population without improved rules lifestyle changes. This suggests the usefulness of evaluating a therapeutic education program for atheromatous disease.

[Venous air emboli in a 4 year old child]

A 4 year old girl is referred to our institution for resection of a nephroblastoma with an extension of the tumor into the lumen of the inferior vena cava. To perform a correct resection of the tumor, the operation was conducted under cardiopulmonary bypass. At the end of the procedure, a bilateral mydriasis was noticed. A CT-scan concluded to a massive venous air emboli. As the procedure was unventful, and no other cause of air emboli was found, the etiology of this emboli is problably retrograde because of the large opening of the inferior vena cava that was required to remove the tumor. To avoid similar case the use of transcranial doppler monitoring may be of interest.

Safety and efficacy of rituximab treatment for vasculitis in hepatitis B virus-associated type II cryoglobulinemia: a case report

Introduction

Systemic B-cell depletion and clinical remission of the systemic effects of cryoglobulins have already been achieved using rituximab in hepatitis C virus-positive immunocompetent patients. Conversely, to the best of our knowledge there are no reports in the literature regarding the use of rituximab in hepatitis B virus-associated cryoglobulinemia.

Case presentation

We report here the case of a 60-year-old Caucasian man who presented with hepatitis B virus-associated type II cryoglobulinemia with severe multisystem disease, including membranoproliferative glomerulonephritis with acute renal failure. The vasculitis was refractory to conventional and antiviral therapy but rituximab use led to a fall in cryoglobulin levels and disease control. The B-cell depletion was safe and efficient to induce a complete remission of the disease.

Conclusion

Our case highlights the benefit and the efficacy of rituximab in association with antiviral therapy in small vessel vasculitis related to hepatitis B virus-associated mixed cryoglobulinemia.

Esophageal dysmotility associated with systemic sclerosis: a high-resolution manometry study

Esophageal involvement occurs in about 80% of patients with systemic sclerosis, with a marked diminution of peristaltic pressures in the distal two-thirds of the esophagus. Our aims were to more fully characterize esophageal motility disorders in systemic sclerosis using high-resolution manometry (HRM) and to determine predictive factors of esophageal involvement. Fifty-one patients (46 females) with systemic sclerosis were included in this retrospective study. Esophageal motility was characterized with HRM. The demographic data, esophageal symptoms, presence of other organ involvement, and autoantibody profile (anti-Scl70 antibodies [Scl70], anticentromere antibodies [ACA]) were recorded for all patients. Esophageal body dysmotility was present in 33 patients (67.3%) and was associated with hypotensive esophagogastric junction in 27 patients (55.1%). The velocity of proximal contractions was higher in patients with esophageal body dysmotility compared to patients with normal peristalsis (median 10.8 cm/s vs. 5.5, P = 0.04). The amplitude of middle esophageal contraction but not of distal esophageal contraction was reduced in patients with hypoperistalsis. Diffuse esophageal skin involvement, presence of Scl70 and absence of ACA were associated with esophageal involvement. Esophageal symptoms encountered in 87.5% of patients were not predictive of esophageal dysmotility. This HRM series confirms the high prevalence of esophageal body dysmotility in systemic sclerosis. Diffuse skin involvement, positive Scl70 and negative ACA, but not esophageal symptoms, may predict esophageal body dysmotility.

F-18 FDG-PET/CT in aseptic abscesses with recurrent febrile abdominal pain

OBJECTIVE

Mendelian and complex autoinflammatory disorders frequently manifest as recurrent abdominal pain and fever. Diagnosis may be difficult and scant data are available about the interest of 2-deoxy-2-[18F]fluoro-D-glucose-positron emission tomography/computed tomography (FDG-PET/CT) in such conditions, particularly aseptic abscesses (AA).

MATERIAL AND METHODS

We analyzed five cases of AA in which FDG-PET/CT was performed at diagnosis (n = 2) and after a suspected relapse (n = 5). Follow-up FDG-PET/CT was performed in two patients 9 days and 6 weeks after the initiation of oral corticosteroids.

RESULTS

FDG-PET/CT showed intense uptake foci in the abdominal lymph nodes (n = 4), liver (n = 2) and spleen (n = 4) before treatment. A marked metabolic response was observed while patients were being treated. In a relapsing patient with abdominal pain but no raised CRP, although CT scan was unchanged, abnormal uptake of FDG was observed. By contrast, some lesions previously observed on CT scan displayed no fixation on new FDG-PET/CT and were suggestive of sequelae in three patients.

CONCLUSION

Although nonspecific, FDG-PET/CT may be an interesting tool for the diagnosis and management of recurrent and febrile abdominal pain in AA. At the time of relapse, it can differentiate between a sequela of previous flares and a new localization. It can be used for whole-body screening to look for other asymptomatic disease localizations.

The systemic capillary leak syndrome: a case series of 28 patients from a European registry

BACKGROUND

The systemic capillary leak syndrome (SCLS) is a rare disease characterized by life-threatening attacks of capillary hyperpermeability.

OBJECTIVE

To describe the clinical characteristics, laboratory findings, treatments, and outcomes of patients with SCLS who were not previously reported in the literature.

DESIGN

Case series.

SETTING

Patients referred to a European multicenter SCLS registry between January 1997 and July 2010.

PATIENTS

28 patients with SCLS.

MEASUREMENTS

Frequency, severity of attacks, and vital status were assessed every 6 months, from diagnosis to the end of the study.

RESULTS

13 men and 15 women referred to the registry who were not previously reported in the literature had 252 attacks. Median age at disease onset was 49.1 years (range, 5.4 to 77.7 years), and median annual frequency of attacks was 1.23 (range, 0.13 to 21.18) per patient. Monoclonal IgG gammopathy was observed in 25 patients (89%). Preventive treatment included intravenous immunoglobulin (n = 18), terbutaline (n = 9), and aminophylline (n = 10). Eight patients died (29%); 1-year survival was 89%, and 5-year survival was 73%. Death was directly related to SCLS attacks in 6 of 8 cases (75%). In 10 patients with a prediagnosis period greater than 6 months who received preventive treatment, the annual frequency of attacks after diagnosis decreased by a median of 1.55 (range, 0.14 to 8.84) per patient. Five years after diagnosis, survival was 85% in 23 patients who had received prophylactic treatment and 20% in 5 patients who had not.

LIMITATION

The benefits of preventive treatment could not be precisely ascertained because of the small sample size and because most patients received several treatments.

CONCLUSION

Clinical experience with these 28 patients with SCLS suggests that prophylactic treatment with β(2)-agonists or intravenous immunoglobulin may reduce the frequency and severity of attacks and may improve survival.

[Recurrent aseptic meningitis secondary to nonsteroidal anti-inflammatory drugs in a patient with lupus]

We report a 39-year-old woman with systemic lupus who presented with recurrent aseptic meningitis secondary to treatment with nonsteroidal anti-inflammatory drugs (NSAIDs). She presented two episodes following ibuprofen administration that were characterized by aseptic meningitis with high protein level in cerebrospinal fluid, and increased serum acute phase reactants. No evidence of an infection or vasculitis was documented. Clinical manifestation resolved rapidly with ibuprofen discontinuation, and corticosteroids therapy was unnecessary. Aseptic meningitis related to NSAIDs reported in lupus patients should be considered because of their specific modality of care and their favourable outcome.

Reactive hemophagocytic syndrome in adult-onset Still disease: clinical features and long-term outcome: a case-control study of 8 patients

Reactive hemophagocytic syndrome (RHS) is a rare, life-threatening, and little-known complication of rheumatic diseases. This disorder is characterized by fever, pancytopenia, liver failure, coagulopathy, and neurologic symptoms. RHS may develop in patents who have lymphoma, organ transplantation, serious infection, and rheumatic diseases, most notably systemic lupus erythematosus and adult-onset Still disease (AOSD). Observations of specific cases of RHS in AOSD remain rare, and the significance of this syndrome during the course of AOSD remains unknown. We retrospectively studied 16 episodes of AOSD-associated RHS in 8 patients. To determine whether RHS is associated with a particular phenotype of AOSD, we conducted a case-control study from the cohort of AOSD patients seen during the same period. The estimated frequency of RHS in AOSD patients from our cohort was 15.3% (8/52). The median age at RHS diagnosis was 44.5 years. We collected clinical and laboratory data. RHS was the first manifestation of AOSD in 7 cases. The main symptoms were fever (n = 8), salmon rash (n = 6), arthralgia (n = 7), lymphadenopathy (n = 6), and shock (n = 4). Serum ferritin concentration was consistently elevated (>1000 microg/L in 8 cases), and the level of glycosylated ferritin was low in all cases (<5% in 7 cases, 15% in 1 case). Six patients presented with coagulopathy; hypertriglyceridemia was found in 6 cases. Admission to the intensive care unit was required in 4 cases. Treatment included corticosteroids (n = 8) and intravenous immunoglobulin (n = 6), cyclophosphamide in 2 cases, infliximab in the same 2 cases, and cyclosporine in 1 case. With a follow-up ranging from 2 to 15 years, the patients were in remission with prednisone plus methotrexate (n = 4), prednisone plus infliximab (n = 2), and low-dose prednisone alone (n = 2). We compared the 8 patients included in this study with 44 control patients with AOSD without RHS. Low haptoglobin levels, very high ferritin levels (>10,000 microg/L), and a normal or low neutrophil count seem to be predictive factors of the occurrence of RHS in AOSD.
