Multiple sclerosis broke my heart.

We report 5 cases of acute heart failure (AHF) related to multiple sclerosis (MS) relapses. AHF was inaugural in 3 patients, always preceded or accompanied by signs of brainstem dysfunction; it was severe, requiring intensive care management. Echocardiography showed left ventricular hypokinesis. No other cause of AHF has been found. All patients showed a new medullary lesion on brain magnetic resonance imaging. All had rapid and complete recovery of ventricular function after intravenous corticosteroids. We concluded that the cases represent a takotsubo phenomenon. Physicians should be aware of rare cases of takotsubo cardiomyopathy in MS relapses. Ann Neurol 2017;81:754-758.

Rituximab versus azathioprine for maintenance in ANCA-associated vasculitis.

BACKGROUND: The combination of cyclophosphamide and glucocorticoids leads to remission in most patients with antineutrophil cytoplasm antibody (ANCA)-associated vasculitides. However, even when patients receive maintenance treatment with azathioprine or methotrexate, the relapse rate remains high. Rituximab may help to maintain remission. METHODS: Patients with newly diagnosed or relapsing granulomatosis with polyangiitis, microscopic polyangiitis, or renal-limited ANCA-associated vasculitis in complete remission after a cyclophosphamide-glucocorticoid regimen were randomly assigned to receive either 500 mg of rituximab on days 0 and 14 and at months 6, 12, and 18 after study entry or daily azathioprine until month 22. The primary end point at month 28 was the rate of major relapse (the reappearance of disease activity or worsening, with a Birmingham Vasculitis Activity Score >0, and involvement of one or more major organs, disease-related life-threatening events, or both). RESULTS: The 115 enrolled patients (87 with granulomatosis with polyangiitis, 23 with microscopic polyangiitis, and 5 with renal-limited ANCA-associated vasculitis) received azathioprine (58 patients) or rituximab (57 patients). At month 28, major relapse had occurred in 17 patients in the azathioprine group (29%) and in 3 patients in the rituximab group (5%) (hazard ratio for relapse, 6.61; 95% confidence interval, 1.56 to 27.96; P=0.002). The frequencies of severe adverse events were similar in the two groups. Twenty-five patients in each group (P=0.92) had severe adverse events; there were 44 events in the azathioprine group and 45 in the rituximab group. Eight patients in the azathioprine group and 11 in the rituximab group had severe infections, and cancer developed in 2 patients in the azathioprine group and 1 in the rituximab group. Two patients in the azathioprine group died (1 from sepsis and 1 from pancreatic cancer). CONCLUSIONS: More patients with ANCA-associated vasculitides had sustained remission at month 28 with rituximab than with azathioprine.

How Admission to a Vascular Surgery Department Improves Medical Treatment in Patients with Lower Extremity Peripheral Arterial Disease.

BACKGROUND: All patients with lower extremity peripheral arterial disease (LE-PAD) should benefit from recommended pharmacologic therapies including antiplatelet agents, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers (ARBs), and hydroxy-methyl-glutaryl-coenzyme A reductase inhibitors (statins). In the present study, this triple therapy was defined as the best medical treatment. This study was designed to determine the number of patients who received best medical treatment at admission and at discharge from a vascular surgery department. We also examined the number of patients who received adapted medical treatment and every pharmacologic class separately. Finally, we investigated whether there were differences in prescribing rates according to patient characteristics and cardiovascular history, clinical grade of LE-PAD, and the type of surgery practiced. MATERIALS AND METHODS: This study is a retrospective chart analysis of 140 consecutive patients admitted to the vascular surgery department of our university hospital, between January 1, 2013, and June 30, 2013. To be included, patients required a vascular surgery for peripheral arterial disease with atherosclerosis. Data from guideline-recommended classes of medications (antiplatelet agents, ACE, ARBs, and statins) at the time of admission and discharge were collected and compared. RESULTS: Best medical treatment was prescribed in 44% patients before hospital admission and in 50% at discharge (P = 0.10). Before hospital admission, 84% of patients had antiplatelet therapy compared with 96% at discharge (P = 0.0004); 73% had a statin, compared with 83% at discharge (P = 0.001); 64% had an ACE inhibitor or ARB, compared with 63% at the time of discharge (P = 1).The proportion of patients receiving best medical treatment at admission and discharge increased in case of coronary artery disease (P = 0.004). There was no difference in prescriptions of best medical treatment and best or adapted treatments at admission and discharge according to the severity of LE-PAD or type of revascularization. CONCLUSIONS: Admission to a vascular department significantly increased the rate of prescription of antiplatelet and statin therapy, but no significant improvement was achieved for the prescription of best medical treatment and best or adapted treatments.

Factors associated with Clostridium difficile infection: A nested case-control study in a three year prospective cohort.

BACKGROUND: Clostridium difficile infection (CDI) is a serious medical condition that is associated with substantial morbidity and mortality. Identification of risk factors associated with CDI and prompt recognition of patients at risk is key to successfully preventing CDI. METHODS: A 3-year prospective, observational, cohort study was conducted in a French university hospital and a nested case-control study was performed to identify risk factors for CDI. Inpatients aged 18 years or older, suffering from diarrhea suspected to be related to CDI, were asked to participate. RESULTS: A total of 945 patients were included, of which 233 cases had a confirmed CDI. CDI infection was more common in men (58.4%) (P = 0.04) compared with patients with diarrhea not related to C. difficile. Previous hospitalization (P < 0.001), prior treatment with antibiotics (P = 0.001) or antiperistaltics (P = 0.002), liver disease (P = 0.003), malnutrition (P < 0.001), and previous CDI (P < 0.001) were significantly more common in patients with CDI. Multivariate logistic regression analysis showed that exposure to antibiotics in the last 60 days (especially third generation cephalosporins and penicillins with ß-lactamase inhibitor), chronic renal or liver disease, malnutrition or previous CDI, were associated with an independent high risk of CDI. Age was not related with CDI. CONCLUSIONS: This study showed that antibiotics and some comorbid conditions were predictors of CDI. Patients at high risk of acquiring CDI at the time of admission may benefit from careful monitoring of antibiotic prescriptions and early attention to infection control issues. In future, these "high-risk" patients may benefit from novel agents being developed to prevent CDI.

Rituximab versus azathioprine for ANCA-associated vasculitis maintenance therapy: impact on global disability and health-related quality of life.

OBJECTIVES: To investigate the effects on health-related quality of life (HRQOL) and functional capability of rituximab vs azathioprine for ANCA-associated vasculitis (AAV) maintenance therapy. METHODS: In a 24-month phase III randomised-controlled trial, 115 patients over time received rituximab or azathioprine for AAV maintenance therapy. Mean changes of 36-item Short-form Health Survey (SF-36) and Health Assessment Questionnaire (HAQ) scores from baseline were analysed. RESULTS: Mean improvements of HAQ scores, from baseline to month 24 were significantly better for the rituximab (0.16 points lower) than the azathioprine group (p=0.038). As demonstrated by SF-36, study patients' baseline HRQOL was significantly impaired compared with age- and sex-matched US norms. At month 24, mean changes from baseline of SF-36 physical component score tended to be better for the rituximab group (+3.95 points, p=0.067) whereas mean changes from baseline of the SF-36 mental component score were significantly better for the azathioprine group (+4.23 points, p=0.041). CONCLUSIONS: Azathioprine-treated patients' for AAV maintenance therapy showed a decline in physical abilities when compared to RTX at M24 in the MAINRITSAN trial.

Validity of the global anti-phospholipid syndrome score to predict thrombosis: a prospective multicentre cohort study.

OBJECTIVE: To investigate the validity of the global APS score (GAPSS) to predict thrombosis in patients with autoimmune diseases. METHODS: This prospective cohort study included consecutive patients with aPL or SLE. aPL, aPS-PT and GAPSS were determined. A Cox proportional hazards model assessed the validity of GAPSS and identified other potential independent predictors of thrombosis. RESULTS: One hundred and thirty-seven patients [43.5 (s.d. 15.4) years old; 107 women] were followed up for a mean duration of 43.1 (s.d. 20.7) months. Mean GAPSS was significantly higher in patients who experienced a thrombotic event compared with those without [10.88 (s.d. 5.06) vs 8.15 (s.d. 5.31), respectively, P = 0.038]. In univariate analysis, age [hazard ratio (HR) = 1.04 (95% CI 1.01, 1.08)] and GAPSS above 16 [HR = 6.86 (95% CI 1.90, 24.77)] were each significantly associated with thrombosis during follow-up, while history of arterial thrombosis [HR = 2.61 (95% CI 0.87, 7.82)] failed to reach significance. Among aPL assays, IgG aPS/PT--a component of the GAPSS--was significantly associated with thrombosis [HR = 2.95 (95% CI 1.02, 8.51)]. In multivariate analysis, GAPSS above 16 remained the only significant predictor of thrombosis [HR = 6.17 (95% CI 1.70, 22.40)]. CONCLUSION: This first external validation study confirmed that GAPSS can predict thrombosis in patients with aPL and associated autoimmune diseases.

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 ß(2)-agonists or intravenous immunoglobulin may reduce the frequency and severity of attacks and may improve survival.

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.

A risk score for the management of pregnant women with increased risk of venous thromboembolism: a multicentre prospective study.

Patients with thrombophilia and/or a history of venous thromboembolism (VTE) exhibit a high risk of thrombosis during pregnancy. The present multicentre study prospectively assessed a prophylaxis strategy, based on a risk score, in pregnancies with increased risk of VTE. Among 286 patients included in the study, 183 had a personal history of VTE (63.98%) and 191 patients (66.8%) had a thrombophilia marker. Eighty nine (46.6%) thrombophilic women had a personal history of VTE. Patients were assigned to one of three prophylaxis strategies according to the risk scoring system. In postpartum, all patients received low molecular weight heparin (LMWH) prophylaxis for at least 6 weeks. In antepartum, LMWH prophylaxis was prescribed to 61.8% of patients with high risk of VTE. Among them, 37.7% were treated in the third trimester only and 24.1% were treated throughout pregnancy. In this cohort, one antepartum-related VTE (0.35%) and two postpartum-related VTE (0.7%) occurred. No case of pulmonary embolism was observed during the study period. The rate of serious bleeding was 0.35%. There was no evidence of heparin-induced thrombocytopenia or osteoporosis. The use of a risk score may provide a rational decision process to implement safe and effective antepartum thromboprophylaxis in pregnant women at high risk of VTE.

Influence of age at disease onset in the outcome of paediatric systemic lupus erythematosus.

OBJECTIVES: The aim of this study was to investigate the influence of age at disease onset in the outcome of paediatric SLE (pSLE). METHODS: Fifty-six patients with pSLE, divided into three groups (pre-pubertal, peripubertal and post-pubertal onset), were studied. The SDI (SLICC/ACR Damage Index for SLE), patients' characteristics, disease manifestations and treatments were compared using Fisher's exact test and Kruskal-Wallis test. Kaplan-Meier curves were constructed to compare the risk of damage occurrence. RESULTS: The risk of damage (SDI >or=1) significantly decreased when age at disease onset increased (89% in pre-pubertal pSLE, 57% in peripubertal pSLE and 38% in post-pubertal pSLE). This excess of risk was found in all disease duration intervals studied (1-3, 3-5, 5-8, 8-10, >10 years) and at the end of follow-up. Kaplan-Meier curves indicated a higher and earlier risk of damage in younger patients. Young children showed higher frequency of autoimmune family history. The frequency of neuropsychiatric disorders and damages decreased with age at disease onset (P < 0.05). Cumulative duration of high-dose prednisone (> 0.5 mg/kg/day) and number of immunosuppressive drugs used that seem to contribute to damage significantly increased when age at disease onset decreased. CONCLUSIONS: The risk of damage is inversely correlated with age at disease onset in pSLE. The poorer outcome observed in younger children may be explained by a more severe disease expression, may be a higher infectious susceptibility, and a more aggressive therapy, particularly within the first 6 months of disease course.

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.

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.

Marked improvement of Churg-Strauss vasculitis with intravenous gamma globulins during pregnancy.

Churg-Strauss syndrome (CSS) is an extremely rare disease, and even less common in women of childbearing age. Patients with severe disease or those who are un-responsive to corticosteroids are usually treated with cytotoxic drugs, especially cyclophosphmide. Intravenous immunoglobulin (IVIg) has became a promising, but not completely accepted, form of treatment for systemic vasculitis that is un-responsive to standard therapy. We report a case of a woman who presented with a CSS flare during pregnancy. Because of mono-neuritis, treatment with IVIg was instituted with successful results. Our case not only supports the beneficial effect of IVIg in CSS, but it also illustrates its successful and safe use in a patient who was pregnant. We discuss the indication of IVIg during the course of anti-neutrophil cytoplasm antigen (ANCA) vasculitis during the pregnancy.

Intravenous Immunoglobulins Improve Survival in Monoclonal Gammopathy-Associated Systemic Capillary-Leak Syndrome.

BACKGROUND: Monoclonal gammopathy-associated systemic capillary-leak syndrome, also known as Clarkson disease, is a rare condition characterized by recurrent life-threatening episodes of capillary hyperpermeability in the context of a monoclonal gammopathy. This study was conducted to better describe the clinical characteristics, natural history, and long-term outcome of monoclonal gammopathy-associated systemic capillary-leak syndrome. METHODS: We conducted a cohort analysis of all patients included in the European Clarkson disease (EurêClark) registry between January 1997 and March 2016. From diagnosis to last follow-up, studied outcomes (eg, the frequency and severity of attacks, death, and evolution toward multiple myeloma) and the type of preventive treatments administered were monitored every 6 months. RESULTS: Sixty-nine patients (M/F sex ratio 1:1; mean ± SD age at disease onset 52 ± 12 years) were included in the study. All patients had monoclonal gammopathy of immunoglobulin G type, with kappa light chains in 47 (68%). Median (interquartile range) follow-up duration was 5.1 (2.5-9.7) years. Twenty-four patients (35%) died after 3.3 (0.9-8) years. Fifty-seven (86%) patients received at least one preventive treatment, including intravenous immunoglobulins (IVIg) n = 48 (73.8%), theophylline n = 22 (33.8%), terbutaline n = 22 (33.8%), and thalidomide n = 5 (7.7%). In the 65 patients with follow-up, 5- and 10-year survival rates were 78% (n = 35) and 69% (n = 17), respectively. Multivariate analysis found preventive treatment with IVIg (hazard ratio 0.27; 95% confidence interval, 0.10-0.70; P = .007) and terbutaline (hazard ratio 0.35; 95% confidence interval, 0.13-0.96; P = .041) to be independent predictors of mortality. CONCLUSIONS: We describe the largest cohort to date of patients with well-defined monoclonal gammopathy-associated systemic capillary-leak syndrome. Preventive treatment with IVIg was the strongest factor associated with survival, suggesting the use of IVIg as the first line in prevention therapy.

Use of calibrated automated thrombinography +/- thrombomodulin to recognise the prothrombotic phenotype.

There is currently no validated method to detect a prothrombotic phenotype. The question remains, can tissue factor (TF) induced thrombin generation (TG), as measured with the calibrated automated thrombinography (CAT) technique, according to Hemker et al., recognise a prothrombotic state either as such, or when the activated protein C (APC)-system is boosted with thrombomodulin (TM)? We determined the normal range of CAT-TG +/- TM in a group of 71 healthy blood donors, in 11 healthy women using oral contraceptives (OC), and in 89 patients with a history of venous thromboembolism (VTE), divided into a group of 50 in which a prothrombotic risk factor could be found (VTEprf+) and 39 others (VTEprf-). The endogenous thrombin potential (ETP) in the OC, VTEprf+ and VTEprf- group was significantly higher than for the controls. In the presence of TM, the differences were significantly higher than in its absence. The VTEprf+ group had a higher ETP, +/- TM than the VTEprf-group. In conclusion, TG, measured with the CAT technique in the presence of TM is capable of detecting the prothrombotic phenotype with a high sensitivity of 0.93 (95% confidence limits 0.82-0.99).

Long-Term Followup of a Multicenter Cohort of 101 Patients With Eosinophilic Granulomatosis With Polyangiitis (Churg-Strauss).

OBJECTIVE: To assess the long-term outcome in eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA). METHODS: A total of 101 patients fulfilling the American College of Rheumatology criteria for EGPA were included between 1990 and 2011. Clinical features, antineutrophil cytoplasm autoantibodies (ANCAs), and Five-Factors Score (FFS) were assessed at diagnosis. Overall and cumulative survival rates, relapse-free survival, and sequelae were studied based on ANCA status and FFS. RESULTS: The rate of cardiomyopathy did not differ according to ANCA status. A total of 79.6% of patients achieved first remission, but 81.1% relapsed. ANCA-positive patients did not relapse more frequently but exhibited more severe disease with mononeuritis (P = 0.0004) and renal involvement (P = 0.02). Being Italian was the only prognostic factor associated with a higher relapse-free survival (P = 0.01), thanks to a longer maintenance of immunosuppressive drugs, suggesting the need for prolonged low-dose corticosteroids. Overall, survival reached 93.1% after a median followup of 6 years. No factor was associated with mortality, but patients over age 65 years with cardiomyopathy or ANCA positivity had more serious outcomes. Sequelae affected 83.2% of patients. Ear, nose, and throat (ENT) involvement was a protective factor for renal (P = 0.04) and cardiac (P = 0.03) morbidity. ANCA positivity was correlated with chronic kidney disease (P = 0.03) and chronic neurologic disability (P = 0.02). CONCLUSION: The actual challenges of EGPA management concern morbidity prevention and quality of life improvement. Long-term corticosteroid treatment appears to reduce relapse risk. ENT involvement is associated with less renal and cardiac morbidity. ANCA positivity predicts renal and neurologic damage.

Observational Study of a French and Belgian Multicenter Cohort of 23 Patients Diagnosed in Adulthood With Mevalonate Kinase Deficiency.

The aim of this study was to describe the clinical and biological features of Mevalonate kinase deficiency (MKD) in patients diagnosed in adulthood. This is a French and Belgian observational retrospective study from 2000 to 2014. To constitute the cohort, we cross-check the genetic and biochemical databases. The clinical, enzymatic, and genetic data were gathered from medical records. Twenty-three patients were analyzed. The mean age at diagnosis was 40 years, with a mean age at onset of symptoms of 3 years. All symptomatic patients had fever. Febrile attacks were mostly associated with arthralgia (90.9%); lymphadenopathy, abdominal pain, and skin lesions (86.4%); pharyngitis (63.6%); cough (59.1%); diarrhea, and hepatosplenomegaly (50.0%). Seven patients had psychiatric symptoms (31.8%). One patient developed recurrent seizures. Three patients experienced renal involvement (13.6%). Two patients had angiomyolipoma (9.1%). All but one tested patients had elevated serum immunoglobulin (Ig) D level. Twenty-one patients had genetic diagnosis; most of them were compound heterozygote (76.2%). p.Val377Ile was the most prevalent mutation. Structural articular damages and systemic AA amyloidosis were the 2 most serious complications. More than 65% of patients displayed decrease in severity and frequency of attacks with increasing age, but only 35% achieved remission. MKD diagnosed in adulthood shared clinical and genetic features with classical pediatric disease. An elevated IgD concentration is a good marker for MKD in adults. Despite a decrease of severity and frequency of attacks with age, only one-third of patients achieved spontaneous remission.

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.

Hemophagocytic Lymphohistiocytosis in Intensive Care Unit: A 71-Case Strobe-Compliant Retrospective Study.

Hemophagocytic lymphohistiocytosis (HLH) is a critical condition that may lead to organ failure and early death. The aim of this retrospective observational study was to describe a cohort of HLH patients admitted to intensive care unit (ICU) and investigate the risk factors of early death.A positive HLH diagnosis was defined by an HScore ≥ 169. Univariate and multivariate analyses were carried out to investigate hospital and 28-day mortality risk factors. Between January 2002 and July 2014, 71 HLH cases were seen at our institution.The overall 28-day mortality (start at ICU admission) and hospital mortality were 38% and 68%, respectively. The factors associated with increased 28-day mortality were the sequential organ failure assessment score at ICU admission (P < .001) and advance in age (P = 0.03). The factors associated with increased hospital mortality were a high sequential organ failure assessment score at ICU admission (P < 0.01), advance in age (P = 0.04), and the presence of lymphoma-related HLH or HLH of unknown origin (P < 0.01).Organ failure overtops the classical early-death risk factors in adult ICU-admitted HLH patients. This failure and the subsequent early death may be prevented by timely specific cytotoxic therapies and the control of the underlying disease.

Treatment of systemic necrotizing vasculitides in patients aged sixty-five years or older: results of a multicenter, open-label, randomized controlled trial of corticosteroid and cyclophosphamide-based induction therapy.

OBJECTIVE: To investigate a new therapeutic strategy, with rapid corticosteroid dose tapering and limited cyclophosphamide (CYC) exposure, for older patients with systemic necrotizing vasculitides (SNVs; polyarteritis nodosa [PAN], granulomatosis with polyangiitis [Wegnener's] [GPA], microscopic polyangiitis [MPA], or eosinophilic GPA [Churg-Strauss] [EGPA]). METHODS: A multicenter, open-label, randomized controlled trial comprising patients ≥65 years old and newly diagnosed as having SNV was conducted. The experimental treatment consisted of corticosteroids for ∼9 months and a maximum of six 500-mg fixed-dose intravenous (IV) CYC pulses, every 2-3 weeks, then maintenance azathioprine or methotrexate. The control treatment included ∼26 months of corticosteroids for all patients, combined with 500 mg/m(2) IV CYC pulses, every 2-3 weeks until remission, then maintenance for all patients with GPA or MPA and for those with EGPA or PAN with a Five-Factors Score (FFS) of ≥1. Randomization used a 1:1 ratio computer-generated list and was performed centrally with sealed opaque envelopes. The primary outcome measure was ≥1 serious adverse event (SAE) occurring within 3 years of followup. Secondary outcome measures included remission and relapse rates. RESULTS: Among the 108 patients randomized, 4 were excluded (early consent withdrawal or protocol violation). Mean ± SD age at diagnosis was 75.2 ± 6.3 years. Analysis at 3 years included 53 patients (21 GPA, 21 MPA, 8 EGPA, and 3 PAN) in the experimental arm and 51 patients (15 GPA, 23 MPA, 6 EGPA, and 7 PAN) in the conventional arm. In total, 32 (60%) versus 40 (78%) had ≥1 SAE (P = 0.04), most frequently infections; 6 (11%) versus 7 (14%) failed to achieve remission (P = 0.71); 9 (17%) versus 12 (24%) died (P = 0.41); and 20 (44%) of 45 versus 12 (29%) of 41 survivors in remission experienced a relapse (P = 0.15). CONCLUSION: For older SNV patients, an induction regimen limiting corticosteroid exposure and with fixed low-dose IV CYC pulses reduces SAEs in comparison to conventional therapy, and does not affect the remission rate. Three-year relapse rates remain high for both arms.
