RESUMO

AIM: To assess the impact of complementary feeding bottles given at maternity hospital and/or over the first month after discharge from the maternity ward on cow's milk allergy (CMA) risk in breastfed infants. METHODS: Case-control study involving infants aged 6-9 months and who were breastfed for at least 1 month. RESULTS: In 554 cases with a diagnosis of CMA and 211 controls, feeding bottles at maternity hospital, feeding bottles during the first month of life, avoidance of dairy products during pregnancy or breastfeeding, family history of allergy, intake of antibiotics and consumption of proton-pump inhibitors or antacids by the infant during the first month of life were associated with increased risk of CMA in a univariate model. In a multivariate model, only feeding bottle at maternity hospital (OR = 1.81 [1.27; 2.59]), family history of allergy (OR = 2.83 [2.01; 3.99]) and avoidance of dairy products during pregnancy or breastfeeding (OR = 5.62 [1.99; 15.87]) were independent risk factors of CMA. CONCLUSION: Complementary bottles given at maternity hospital to newborns who will be exclusively breastfed increases the later risk of CMA. Similarly, avoidance of dairy products during pregnancy or breastfeeding should be discouraged.

RESUMO

Background: Hereditary angioedema (HAE) is characterized by unpredictable and potentially life-threatening attacks of cutaneous and submucosal swelling. Over the past decade, new agents, based on a better understanding of the underlying biologic mechanisms of HAE, have changed the face of long-term prophylaxis (LTP). Objective: The objective was to describe current practices and unmet needs with regard to LTP for HAE in expert centers in France. Methods: The study was conducted in France in 2020. Based on their experience with patients with HAE who had visited their center at least once in the past 3 years, physicians from 25 centers who are expert in the management of HAE were requested to fill in a questionnaire that encapsulated their active patient list, criteria for prescribing LTP, and medications used. They were asked about potential unmet needs with currently available therapies. They were asked to express their expectations with regard to the future of HAE management. Results: Analysis was restricted to 20 centers that had an active patient file and agreed to participate. There were 714 patients with C1 inhibitor (C1-INH) deficiency, of whom 423 (59.2%) were treated with LTP. Altered quality of life triggered the decision to start LTP, as did the frequency and severity of attacks. Ongoing LTP included androgens (28.4%), progestins (25.8%), lanadelumab (25.3%), tranexamic acid (14.2%), intravenous C1-INHs (5.6%), and recombinant C1-INH (0.7%). Twenty-nine percent of the patents with LTP were considered to still have unmet needs. Physicians' concerns varied among therapies: poor tolerability for androgens and progestins, a lack of efficacy for tranexamic acid and progestins, dosage form, and high costs for C1-INHs and lanadelumab. Physicians' expectations encompassed more-efficacious and better-tolerated medications, easier treatment administration for the sake of improved quality of life of patients, and less-expensive therapies. Conclusion: Despite the recent enrichment of the therapeutic armamentarium for LTP, physicians still expressed unmet needs with currently available therapies.

RESUMO

OBJECTIVES: Systemic lupus erythematosus (SLE) is a chronic autoimmune multi-organ disease with an unpredictable course. SLE causes functional disability, changes in body appearance, and psychological distress. When faced with SLE, patients have to implement coping strategies. Therefore, the aim of this study was to describe patients' coping strategies, consider the implications for a personalised practice of patient education and evaluate patients' adherence to HCQ treatment. METHODS: One hundred and fifty-eight SLE patients receiving hydroxychloroquine (HCQ) treatment entered a prospective, non-comparative, longitudinal study aimed at describing patients' coping strategies and evaluating their adherence to the HCQ regimen. Coping strategies were evaluated using an abbreviated French version of the WCC-27 exploring 3 dimensions of coping: problem-centered coping, emotion-centered coping and search for social support. Adherence was assessed by the MASRI, the MMAS-8 and also objectively assessed by the patient's serum level of HCQ. Data collected at study entry also included disease activity: SLEDAI, and disease extent: SLICC damage index. The prevalence of anxious and depressive symptoms was evaluated with the HADS. Quality of life was evaluated using the LupusQoL questionnaire. RESULTS: Patients were clustered using an unsupervised hierarchical classification based on coping strategies. Four clusters of patients were individualised. The cluster of patients with low problem-centered coping, high emotion-centered coping and the lowest search for social support had worse quality of life and more psychological distress. We did not find any inter-cluster differences in terms of compliance to HCQ. CONCLUSIONS: Patients' knowledge is not the only parameter to consider for a personalised educational therapy: psychological parameters such as coping must also be considered to ensure the best possible quality of life. For educational therapy purposes, it is important not to group patients with the same coping style; heterogenous groups will enable patients to share their experiences and learn from the coping strategies of others.

RESUMO

PURPOSE: Subcutaneous immunoglobulin replacement therapy (IgRT) may be administered once a week with a pump or every other day with a syringe (rapid push). The objective of the study was to compare the impact of pump and rapid push infusions on patient's life quality index (LQI). METHODS: This study was a randomized, crossover, multicenter, non-inferiority trial conducted in adults with primary immunodeficiency (PID) accustomed to weekly infusions at home by pump. Patients used pump or rapid push for 3 months each according to the randomized sequence. Main criterion was PID-LQI factor I (treatment interference). Non-inferiority ratio was set at 90%. RESULTS: Thirty patients entered the study; 28 completed the two periods. IgRT exposure was similar during each period. At the end of each period, mean LQI factor 1 was 87.0 (IC95% [80.3; 94.3]) and 77.80 (IC95% [71.5; 84.7]) for pump and rapid push, respectively. There was a slightly larger effect of rapid push on treatment interference than with pump so that the primary endpoint could not be met. No difference was found on other LQI components, satisfaction (TSQM), or quality of life (SF36v2). Eight patients declared to prefer rapid push while 19 others preferred pump. Of rapid push infusions, 67.2% led to local reactions vs 71.8% of pump infusions (p = 0.11) illustrating its good tolerance. Rapid push and pump infusions achieved similar trough IgG levels with similar incidence of infections. Rapid push saved 70% of administration cost when compared to pump. CONCLUSIONS: Since IgRT is a lifelong treatment in PID patients, individualization of treatment is of paramount importance. Rapid push is a new administration method in the physician's armamentarium which is preferred by some patients and is cost-effective. CLINICALTRIALS. GOV IDENTIFIER: NCT02180763 CLINICAL IMPLICATIONS: Self-administration of small volumes of immunoglobulins at home, every other day, using a syringe (rapid push) is a cost-effective alternative to administration of larger volumes by pump once a week. This study compared subcutaneous infusions of immunoglobulins either weekly via a pump or every other day via a syringe (rapid push). Rapid push is preferred by some patients and is cost-effective, therefore completing a physician's armamentarium.

RESUMO

OBJECTIVE: To describe the characteristics of patients suffering from secondary immunodeficiencies (SID) associated with hematological malignancies (HM), who started immunoglobulin replacement therapy (IgRT), physicians' expectations regarding IgRT, and IgRT modalities. METHODS: Non-interventional, prospective French cross-sectional study. RESULTS: The analysis included 231 patients (66 ± 12 years old) suffering from multiple myeloma (MM) (N = 64), chronic lymphoid leukemia (CLL) (N = 84), aggressive non-Hodgkin B-cell lymphoma (aNHL) (N = 32), indolent NHL (N = 39), acute leukemia (N = 6), and Hodgkin disease (N = 6). Of the HM, 47% were currently treated, 42% were relapsing or refractory, 23% of patients had received an autologous hematopoietic stem-cell transplant, and 1% had received an allograft. Serum immunoglobulin trough levels in 195 individuals were less than 5 g/L in 68.7% of cases. Most patients had a history of recurrent infections. Immunoglobulin dose was about 400 mg/kg/mo. Half of patients started with subcutaneous infusion. When starting IgRT, physicians mainly expected to prevent severe and moderate infections. They also anticipated improvement in quality of life and survival which is beyond evidence-based medicine. CONCLUSION: NHL is a frequent condition motivating IgRT besides well-recognized indications. Physicians mainly based the decision of starting IgRT on hypogammaglobulinemia and recurrence of infections but, irrespective of current recommendations, were also prepared to start IgRT prophylactically even in the absence of a history of infections.

RESUMO

OBJECTIVE: To assess the effect of sildenafil, a phosphodiesterase type 5 inhibitor, on digital ulcer (DU) healing in systemic sclerosis (SSc). METHODS: Randomised, placebo-controlled study in patients with SSc to assess the effect of sildenafil 20 mg or placebo, three times daily for 12 weeks, on ischaemic DU healing. The primary end point was the time to healing for each DU. Time to healing was compared between groups using Cox models for clustered data (two-sided tests, p=0.05). RESULTS: Intention-to-treat analysis involved 83 patients with a total of 192 DUs (89 in the sildenafil group and 103 in the placebo group). The HR for DU healing was 1.33 (0.88 to 2.00) (p=0.18) and 1.27 (0.85 to 1.89) (p=0.25) when adjusted for the number of DUs at entry, in favour of sildenafil. In the per protocol population, the HRs were 1.49 (0.98 to 2.28) (p=0.06) and 1.43 (0.93 to 2.19) p=0.10. The mean number of DUs per patient was lower in the sildenafil group compared with the placebo group at week (W) 8 (1.23±1.61 vs 1.79±2.40 p=0.04) and W12 (0.86±1.62 vs 1.51±2.68, p=0.01) resulting from a greater healing rate (p=0.01 at W8 and p=0.03 at W12). CONCLUSIONS: The primary end point was not reached in intention-to-treat, partly because of an unexpectedly high healing rate in the placebo group. We found a significant decrease in the number of DUs in favour of sildenafil compared with placebo at W8 and W12, confirming a sildenafil benefit. TRIAL REGISTRATION NUMBER: NCT01295736.

RESUMO

OBJECTIVES: Despite the wide use of the 6 min walk distance (6MWD), no study has ever assessed its validity as a surrogate marker for haemodynamics and predictor of outcome in isolated pulmonary arterial hypertension associated with systemic sclerosis (SSc-PAH). We designed this work to address this issue. METHODS: Treatment-naïve patients with SSc-PAH were prospectively included from two sources: the French PAH Network (a prospective epidemiological cohort) (n=83) and randomised clinical trials submitted for drug approval (Food and Drug Administration) (n=332). Correlations between absolute values of the 6MWD and haemodynamics at baseline, as well as between variations of 6MWD and haemodynamics during follow-up, were studied in both populations. RESULTS: In the French cohort, baseline cardiac output (CO) (R(2)=0.19, p=0.001) and New York Heart Association class (R(2)=0.10, p<0.001) were significantly and independently correlated with baseline 6MWD in multivariate analysis. A significant, independent, but weaker, correlation with CO was also found in the Food and Drug Administration sample (R(2)=0.04, p<0.001). During follow-up, there was no association between the changes in 6MWD and haemodynamic parameters in patients under PAH-specific treatments. CONCLUSIONS: In SSc-PAH, CO independently correlates with 6MWD at baseline, but accounts for a small amount of the variance of 6MWD in both study samples. This suggests that other non-haemodynamic factors could have an impact on the walk distance. Moreover, variations of 6MWD do not reflect changes in haemodynamics among treated patients. Our results suggest that 6MWD is not an accurate surrogate marker for haemodynamic severity, nor an appropriate outcome measure to assess changes in haemodynamics during follow-up in treated SSc-PAH.

RESUMO

OBJECTIVE: To obtain perspective on epilepsy in patients referred to tertiary centers in France, and describe etiology, epilepsy syndromes, and identify factors of drug resistance and comorbidities. METHODS: We performed a cross-sectional analysis of the characteristics of 5,794 pediatric and adult patients with epilepsy included in a collaborative database in France between 2007 and 2013. Comparisons between groups used Student's t-test or Fisher's exact test for binary or categorical variables. Factors associated with drug resistance and intellectual disability were evaluated in multi-adjusted logistic regression models. RESULTS: Mean age at inclusion was 17.9 years; children accounted for 67%. Epilepsy was unclassified in 20% of patients, and etiology was unknown in 65%, including those with idiopathic epilepsies. Etiologies differed significantly in adult- when compared to pediatric-onset epilepsy; however, among focal structural epilepsies, mesial temporal lobe epilepsy with hippocampal sclerosis began as often in the pediatric as in adult age range. Drug resistance concerned 53% of 4,210 patients evaluable for seizure control and was highest in progressive myoclonic epilepsy (89%), metabolic diseases (84%), focal cortical dysplasia (70%), other cortical malformations (69%), and mesial temporal lobe epilepsy with hippocampal sclerosis (67%). Fifty-nine percent of patients with focal structural epilepsy and 69% with epileptic encephalopathies were drug resistant; however, 40-50% of patients with West syndrome and epileptic encephalopathy with continuous spike-and-waves during sleep were seizure-free. Ages at onset in infancy and in young adults shared the highest risk of drug resistance. Epilepsy onset in infancy comprised the highest risk of intellectual disability, whereas specific cognitive impairment affected 36% of children with idiopathic focal epilepsy. SIGNIFICANCE: Our study provides a snapshot on epilepsy in patients referred to tertiary centers and discloses needs for diagnosis and treatment. Large databases help identify patients with rare conditions that could benefit from specific prospective studies.

RESUMO

BACKGROUND: The aim of this study was to assess health-related quality of life in patients with pulmonary arterial hypertension associated with CHD and correlations with clinical status. METHODS: This prospective cross-sectional observational study included CHD patients with pulmonary arterial hypertension in 14 tertiary-care centres in France. We used two health-related quality of life questionnaires - SF-36 and Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) - and one anxiety/depression Hospital Anxiety and Depression Scale (HADS) questionnaire. RESULTS: Clinical data were collected for the 208 included patients (mean age: 42.6 years, range from 15.1 to 85.8 years, 69.7% female). Most patients were in NYHA functional class II (48.1%) and III (37.5%). Patients' phenotype was classified as Eisenmenger syndrome (70.7%), pulmonary arterial hypertension associated with systemic-to-pulmonary shunts (12.0%), with small defects (3.4%), or after corrective cardiac surgery (13.9%). In total, 76.4% of the patients were receiving pulmonary arterial hypertension-specific treatments. SF-36 scores showed impairment compared with normalised data. Health-related quality of life scores were significantly lower in females than in males for most dimensions of both questionnaires and were independent of the patients' phenotype, even after gender adjustment - except for CAMPHOR functioning - but significantly depended on NYHA functional class. The Hospital Anxiety and Depression Scale (HADS) scores suggested anxiety and depression associated with increasing NYHA functional class but independent of patients' phenotype. NYHA functional class, 6-minute walk distance, HADS, gender, and recent stressful event significantly affected quality of life in the multivariate analysis. CONCLUSIONS: This study showed impairment of quality of life in a large cohort of patients with pulmonary arterial hypertension associated with CHD with both generic and specific questionnaires. NYHA functional class and HADS scores were predictive of most quality of life scores.

RESUMO

OBJECTIVES: The reciprocal links between comorbidities and gout are complex. We used cluster analysis to attempt to identify different phenotypes on the basis of comorbidities in a large cohort of patients with gout. METHODS: This was a cross-sectional multicentre study of 2763 gout patients conducted from November 2010 to May 2011. Cluster analysis was conducted separately for variables and for observations in patients, measuring proximity between variables and identifying homogeneous subgroups of patients. Variables used in both analyses were hypertension, obesity, diabetes, dyslipidaemia, heart failure, coronary heart disease, renal failure, liver disorders and cancer. RESULTS: Comorbidities were common in this large cohort of patients with gout. Abdominal obesity, hypertension, metabolic syndrome and dyslipidaemia increased with gout duration, even after adjustment for age and sex. Five clusters (C1-C5) were found. Cluster C1 (n=332, 12%) consisted of patients with isolated gout and few comorbidities. In C2 (n=483, 17%), all patients were obese, with a high prevalence of hypertension. C3 (n=664, 24%) had the greatest proportion of patients with type 2 diabetes (75%). In C4 (n=782, 28%), almost all patients presented with dyslipidaemia (98%). Finally, C5 (n=502, 18%) consisted of almost all patients with a history of cardiovascular disease and renal failure, with a high rate of patients receiving diuretics. CONCLUSIONS: Cluster analysis of comorbidities in gout allowed us to identify five different clinical phenotypes, which may reflect different pathophysiological processes in gout.

RESUMO

OBJECTIVE: The aim of this study was to assess the prognostic value of systolic pulmonary artery pressure (sPAP) estimated by echocardiography in the multinational European League Against Rheumatism Scleroderma Trial and Research (EUSTAR) cohort. METHODS: Data for patients with echocardiography documented between 1 January 2005 and 31 December 2011 were extracted from the EUSTAR database. Stepwise forward multivariable statistical Cox pulmonary hypertension analysis was used to examine the independent effect on survival of selected variables. RESULTS: Based on our selection criteria, 1476 patients were included in the analysis; 87% of patients were female, with a mean age of 56.3 years (s.d. 13.5) and 31% had diffuse SSc. The mean duration of follow-up was 2.0 years (s.d. 1.2, median 1.9). Taking index sPAP of <30 mmHg as reference, the hazard ratio (HR) for death was 1.67 (95% CI 0.92, 2.96) if the index sPAP was between 30 and 36 mmHg, 2.37 (95% CI 1.14, 4.93) for sPAP between 36 and 40 mmHg, 3.72 (95% CI 1.61, 8.60) for sPAP between 40 and 50 mmHg and 9.75 (95% CI 4.98, 19.09) if sPAP was >50 mmHg. In a multivariable Cox model, sPAP and the diffusing capacity for carbon monoxide (DLCO) were independently associated with the risk of death [HR 1.833 (95% CI 1.035, 3.247) and HR 0.973 (95% CI 0.955, 0.991), respectively]. sPAP was an independent risk factor for death with a HR of 3.02 (95% CI 1.91, 4.78) for sPAP ≥36 mmHg. CONCLUSION: An estimated sPAP >36 mmHg at baseline echocardiography was significantly and independently associated with reduced survival, regardless of the presence of pulmonary hypertension based on right heart catheterization.

RESUMO

BACKGROUND: The prevalence and characteristics of pulmonary hypertension in adults with sickle cell disease have not been clearly established. METHODS: In this prospective study, we evaluated 398 outpatients with sickle cell disease (mean age, 34 years) at referral centers in France. All patients underwent Doppler echocardiography, with measurement of tricuspid-valve regurgitant jet velocity. Right heart catheterization was performed in 96 patients in whom pulmonary hypertension was suspected on the basis of a tricuspid regurgitant jet velocity of at least 2.5 m per second. Pulmonary hypertension was defined as a mean pulmonary arterial pressure of at least 25 mm Hg. RESULTS: The prevalence of a tricuspid regurgitant jet velocity of at least 2.5 m per second was 27%. In contrast, the prevalence of pulmonary hypertension as confirmed on catheterization was 6%. The positive predictive value of echocardiography for the detection of pulmonary hypertension was 25%. Among the 24 patients with confirmed pulmonary hypertension, the pulmonary-capillary wedge pressure was 15 mm Hg or less (indicating precapillary pulmonary hypertension) in 11 patients. Patients with confirmed pulmonary hypertension were older and had poorer functional capacity and higher levels of N-terminal pro-brain natriuretic peptide than other patients. In contrast, patients who had a tricuspid regurgitant jet velocity of at least 2.5 m per second without pulmonary hypertension and patients with a tricuspid regurgitant jet velocity of less than 2.5 m per second had similar clinical characteristics. CONCLUSIONS: In this study of adults with sickle cell disease, the prevalence of pulmonary hypertension as confirmed on right heart catheterization was 6%. Echocardiographic evaluation alone had a low positive predictive value for pulmonary hypertension.

RESUMO

OBJECTIVE: To assess the survival and prognostic factors in patients with newly diagnosed incident systemic sclerosis (SSc)-associated pulmonary arterial hypertension (PAH) in the modern management era. METHODS: Prospectively enrolled SSc patients in the French PAH Network between January 2006 and November 2009, with newly diagnosed PAH and no interstitial lung disease, were analysed (85 patients, mean age 64.9±12.2 years). Median follow-up after PAH diagnosis was 2.32 years. RESULTS: A majority of patients were in NYHA functional class III-IV (79%). Overall survival was 90% (95% CI 81% to 95%), 78% (95% CI 67% to 86%) and 56% (95% CI 42% to 68%) at 1, 2 and 3 years from PAH diagnosis, respectively. Age (HR: 1.05, 95% CI 1.01 to 1.09, p=0.012) and cardiac index (HR: 0.49, 95% CI 0.27 to 0.89, p=0.019) were significant predictors in the univariate analysis. We also observed strong trends for gender, SSc subtypes, New York Heart Association functional class, pulmonary vascular resistance and capacitance to be significant predictors in the univariate analysis. Conversely, six-min walk distance, mean pulmonary arterial and right atrial pressures were not significant predictors. In the multivariate model, gender was the only independent factor associated with survival (HR: 4.76, 95% CI 1.35 to 16.66, p=0.015 for male gender). CONCLUSIONS: Incident SSc-associated PAH remains a devastating disease even in the modern management era. Age, male gender and cardiac index were the main prognosis factors in this cohort of patients. Early detection of less severe patients should be a priority.

RESUMO

Human fibrinogen concentrate (Fibryga) received temporary approval for fibrinogen replacement therapy in France (2017), with subsequent full approval for congenital and acquired hypofibrinogenemia. We evaluated real-world use for on-demand treatment of bleeding and prophylaxis to enhance our knowledge on fibrinogen concentrate as an option for fibrinogen replacement. Data were retrospectively collected from adult and pediatric patients with fibrinogen deficiency. The primary end point was indication for fibrinogen concentrate use; the secondary end point was treatment success for on-demand treatment/perioperative prophylaxis. The study included 150 adult (median age, 62 years; range, 18-94 years) and 50 pediatric (median age, 3 years; range, 0.01-17 years) patients with acquired fibrinogen deficiency. Fibrinogen concentrate was administered to 47.3% for nonsurgical bleeding, 22.7% for surgical bleeding, and 30.0% for perioperative prophylaxis in adult patients, and to 4.0% for surgical bleeding and 96.0% for perioperative prophylaxis in pediatric patients. Cardiac surgeries accounted for 79.5%/75.0% perioperative prophylaxis and 82.4%/100.0% surgical bleeding cases in adult/pediatric patients, respectively. The mean ± standard deviation (SD, median) total fibrinogen doses were 3.06 ± 1.69 g (32.61 mg/kg), 2.09 ± 1.36 g (22.99 mg/kg), and 2.36 ± 1.25 g (29.67 mg/kg) for adult nonsurgical bleeding, surgical bleeding, and perioperative prophylaxis, respectively; doses of 0.75 ± 0.35 g (47.64 mg/kg) and 0.83 ± 0.62 g (55.56 mg/kg) were used for pediatric surgical bleeding and perioperative prophylaxis, respectively. Treatment success was 85.7%/97.1/93.3% in adults and 50.0%/87.5% in pediatrics for nonsurgical bleeding (adults only), surgical bleeding, and perioperative prophylaxis, respectively. Fibrinogen concentrate demonstrated favorable effectiveness and safety across the age groups. This study contributes to evidence supporting fibrinogen concentrate for bleeding control/prevention in real-world clinical practice, particularly for patients with acquired fibrinogen deficiency.

RESUMO

OBJECTIVE: Pulmonary arterial hypertension (PAH) is a severe, life-limiting complication of systemic sclerosis (SSc). Guidelines recommend early detection and management of SSc-PAH. However, little is known about the impact of detection programs on patients with SSc-PAH. This study was undertaken to assess the clinical characteristics of patients with SSc-PAH at diagnosis and their long-term outcomes. METHODS: Two incident cohorts of patients with SSc-PAH from the same management era (2002/2003) were studied. The first cohort (designated the routine practice cohort) included consecutive adult patients with symptomatic SSc in whom a diagnosis of PAH was made by right-sided heart catheterization (RHC) at the time of recruitment into the French PAH Registry. The second cohort (designated the detection cohort) comprised consecutive patients with SSc who entered a systematic PAH detection program and were subsequently found to have PAH on RHC. Clinical characteristics at diagnosis of PAH and subsequent 8-year mortality were compared between the cohorts. RESULTS: There were 16 patients in each cohort. At the time of PAH diagnosis, patients in the detection cohort had less advanced pulmonary vascular disease compared with patients in the routine practice cohort, as evidenced by more patients being in New York Heart Association class I and class II, a lower mean pulmonary artery pressure and pulmonary vascular resistance index, and a higher cardiac output. Patients in the detection cohort were less likely to receive diuretics and warfarin, but there was no difference in exposure to PAH-specific therapies between the cohorts. The 1-, 3-, 5-, and 8-year survival rates were 75%, 31%, 25%, and 17%, respectively, in the routine practice cohort compared with 100%, 81%, 73%, and 64%, respectively, in the detection cohort (P = 0.0037). CONCLUSION: Compared with patients in routine clinical practice, PAH detection programs in SSc are able to identify patients with milder forms of the disease, allowing earlier management.

RESUMO

INTRODUCTION: Prothrombin Complex Concentrate (PCC) is a key treatment in the management of bleeding related to Vitamin K antagonists (VKA). This study aimed to evaluate prospectively PCC use in patients with VKA-related bleeding in view of the French guidelines published in 2008. METHODS: All consecutive patients with VKA-related bleeding treated with a 4-factor PCC (Octaplex®) were selected in 33 French hospitals. Collected data included demographics, site and severity of bleeding, modalities of PCC administration, International Normalized Ratio (INR) values before and after PCC administration, outcomes and survival rate 15 days after infusion. RESULTS: Of 825 patients who received PCC between August 2008 and December 2010, 646 had severe bleeding. The main haemorrhage sites were intracranial (43.7%) and abdominal (24.3%). Mean INR before PCC was 4.4 ± 1.9; INR was unavailable in 12.5% of patients. The proportions of patients who received a PCC dose according to guidelines were 15.8% in patients with initial INR 2-2.5, 41.5% in patients with INR 2.5-3, 40.8% in patients with INR 3-3.5, 26.9% in patients with INR > 3.5, and 63.5% of patients with unknown INR. Vitamin K was administered in 84.7% of patients. The infused dose of PCC did not vary with initial INR; the mean dose was 25.3 ± 9.8 IU/Kg. Rates of controlled bleeding and target INR achievement were similar, regardless of whether or not patients were receiving PCC doses as per the guidelines. No differences in INR after PCC treatment were observed, regardless of whether or not vitamin K was administered. INR was first monitored after a mean time frame of 4.5 ± 5.6 hours post PCC. The overall survival rate at 15 days after PCC infusion was 75.4% (65.1% in patients with intracranial haemorrhage). A better prognosis was observed in patients reaching the target INR. CONCLUSIONS: Severe bleeding related to VKA needs to be better managed, particularly regarding the PCC infused dose, INR monitoring and administration of vitamin K. A dose of 25 IU/kg PCC appears to be efficacious in achieving a target INR of 1.5. Further studies are required to assess whether adjusting PCC dose and/or better management of INR would improve outcomes.

RESUMO

OBJECTIVES: New Caledonia is a Pacific island of 270,000 inhabitants with mixed ethnicities, including Polynesians (10.2%), people from European ancestry (27.2%), and Melanesians (39.1%),. This study aimed at determining the prevalence of gout and hyperuricemia in the general population and the various ethnicities of New Caledonia. METHODS: A 3-degree random sample of the population aged 18 to 60 years was adjusted according to the 2014 New Caledonia census. Face-to-face planned interviews and physical measurements were performed by trained nurses. All consenting participants underwent capillary measurement of creatinine; all consenting men and only women older than 40 years underwent point-of-care uricemia testing. Gout was defined by a validated algorithm. Two definitions of hyperuricemia were used: capillary level equivalent to plasma uric acid level>360µmol/l (6mg/dl) and>420µmol/l (7mg/dl) and/or urate-lowering drug treatment for both thresholds. RESULTS: We included 1144 participants (adjusted mean age 37.7±12.0 years; adjusted sex ratio 50.4% men). The adjusted prevalence of gout was 3.3% (95% confidence interval 2.2-4.9). Prevalence was 6.7% (2.5-16.8), 4.1% (1.8-8.9), and 2.6% (1.4-4.7) for Polynesians, Europeans and Melanesians, respectively, and 1.9% (0.5-6.6) for other ethnicities. Prevalence of hyperuricemia, determined in 658 participants, was 67.0% (61.9-71.6) and 37.0% (32.3-42.0) for the 360- and 420-µmol/l thresholds, respectively, and was significantly greater for Polynesians and Melanesians than Europeans for both thresholds. CONCLUSIONS: The prevalence of gout and hyperuricemia in New Caledonia was high, including in patients of European descent.

RESUMO

PURPOSE: The purpose of the APRIM study (for Adherence Polyarthrite Rhumatoïde Injection Methotrexate) was to investigate the change in treatment adherence of patients with rheumatic arthritis (RA) who switched from oral to subcutaneous methotrexate (MTX). PATIENTS AND METHODS: Prospective, observational study in RA patients treated with MTX and switching from oral to subcutaneous (SC) route in real-life conditions. Data on motivations for switch, disease activity (DAS28-CRP), quality of life (AISM-2 SF), disability (HAQ-DI), and adherence to MTX were collected at inclusion (M0) and 6 months later (M6). Adherence was assessed by the 8-item Morisky Medication Adherence Scale (MMAS-8) and defined as high (MMAS-8 = 8), medium (MMAS-8 = 6 or ≤8) or low (MMAS-8 < 6). The primary evaluation criterion was the proportion of patients who maintained strong adherence or improved adherence by at least one category (from low to medium or strong or from medium to strong) between M0 and M6. RESULTS: The analysis involved 207 patients (age 60.4±12.7 years, 75.2% females). 6.7% were in remission and 15.5% had low disease activity (LDA) at baseline. 58.5% reached the primary criterion and strong adherence rate increased from 42.0% to 50.7%. Change of route was combined with increased MTX dose in 34.8% of patients. Switch to SC route increased the proportion of patients with remission or LDA from 22.8% to 52.9% and increased quality of life even in patients with unchanged MTX dose. CONCLUSION: Overall, change from oral to SC route improved adherence to MTX, RA control and quality of life independently of change in MTX dose.

RESUMO

OBJECTIVE: To describe the history of SSc-associated pulmonary arterial hypertension (SSc-PAH) in patients with New York Heart Association (NYHA) functional class (FC) II dyspnoea at diagnosis. METHODS: Data at the time of diagnosis were collected and analysed retrospectively for 77 consecutive patients with SSc-PAH. RESULTS: Twelve patients (15.6%) presented with PAH and NYHA FC II dyspnoea. After a mean follow-up of 44 months, only 4 out of the 12 PAH patients remained stable in FC II, while 8 showed worsening to FC III or IV. Three patients died during the observation period; two from PAH and one from rectal cancer. Survival in patients in FC II at diagnosis was 100, 91 and 80% at 1, 2 and 3 years, respectively. CONCLUSIONS: A majority of patients with mildly symptomatic SSc-PAH in NYHA FC II at diagnosis have a severe disease with poor prognosis.
