Real-World Experience with a Human Fibrinogen Concentrate: Clinical Data from Adult and Pediatric Patients Requiring Fibrinogen for Bleeding Control and Prevention.

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.

Long-term prophylaxis in hereditary angioedema management: Current practices in France and unmet needs.

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.

Epidemiology of gout and hyperuricemia in New Caledonia.

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.

Complementary bottles during the first month and risk of cow's milk allergy in breastfed infants.

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.

Benefits of Switch from Oral to Subcutaneous Route on Adherence to Methotrexate in Patients with Rheumatoid Arthritis in Real Life Setting.

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.

Adherence to hydroxychloroquine in patients with systemic lupus: Contrasting results and weak correlation between assessment tools.

OBJECTIVES: Hydroxychloroquine (HCQ) is an anchor drug in the treatment of systemic lupus erythematosus (SLE). Adherence to HCQ is key for efficacy. Inaccurate evaluation of adherence could lead to non-justified switch to more expensive or less tolerated drugs. METHODS: Severe non-adherence rate to HCQ was estimated in a sample of SLE patients during a routine visit using blood HCQ concentration<200µg/L. Adherence was assessesd by the Medication Adherence Self-Report Inventory (MASRI)<80/100, 8-item Morisky Medication Adherence Scale (MMAS-8) ≤6/8, Health Care Provider (HCP) visual analog scale (VAS)<80/100. Same procedures were to be repeated during a further routine visit 6 to 12 months later. We described agreement and correlations between tools and compared severely non-adherent patients and others on their characteristics. RESULTS: The study involved 158 patients (86.1% females) aged 42.2±12.6 years treated with HCQ for 9.6±6.9 years. Blood HCQ concentration (mean±standard deviation) was 1046±662µg/L at visit 1 and 855±577µg/L at visit 2. At visit 1, the non-adherence rate varied from 3.2% (blood HCQ level<200µg/L) to 7.7% (MASRI), 12.4% (HCP-VAS) or 32.5% (MMAS-8). 37.8% of patients met at least one of the definitions of non-adherence. Patients' characteristics including SLE activity, damage and quality of life were similar between severely non-adherent patients and others. Correlations between blood HCQ-concentration and self-questionnaires were weak (r<0.25) and agreement between methods was poor. CONCLUSION: Blood HCQ concentration<200µg/L reveals severe non-adherence. Combining blood HCQ concentration with MASRI and MMAS-8 may help to better identify non-adherence in SLE. Agreement between methods was poor and correlations with HCQ level and SLE activity were weak.

Recovering autonomy is a key advantage of home-based immunoglobulin therapy in patients with myositis: A qualitative research study.

Immunoglobulins are 2nd or 3rd-line treatments in dermatomyositis (DM) or polymyositis (PM) refractory to high-dose corticosteroids and immunosuppressants. Immunoglobulins (2 g/kg/mo) are usually administered intravenously (IVIg) once a month and the patients stay at hospital for a few days. Recently, subcutaneous injections (SCIg) were proposed 2 to 3 times per week, in some dysimmune diseases. SCIg are administered at home preferably by the patient or by a nurse. We investigated the needs and attitudes of DM and PM patients with experience of IVIg and SCIg.Seven patients (6 PM and 1 DM) from a single center participated in a focus group (N = 6) or underwent in-depth interview (N = 1). Six had the experience of both IVIg at hospital and SCIg at home; 1 has received only IVIg at hospital. Verbatim was recorded and transcribed for further content analysis and computer-aided textual analysis.Clinical profiles and stories were heterogeneous. At diagnosis, muscle weakness, severe pain, and fatigue were at the forefront of patients' complaints impairing daily life. Patients reported considerable improvement with immunoglobulins. SCIg were described as easy, less disruptive for daily life, well tolerated, and less time-consuming. SCIg self-administration at home restored the feeling of autonomy and control.Interviews of DM and PM patients revealed that recovering autonomy and control was a central advantage of home-based SCIg that were efficient, well tolerated, and perceived as a good compromise between treatment burden and efficacy.

Consideration of coping strategies for patients suffering from systemic lupus erythematosus: reflection for a personalised practice of patient education.

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.

Evaluation of serum thymidine kinase 1 activity as a biomarker for treatment effectiveness and prediction of relapse in dogs with non-Hodgkin lymphoma.

BACKGROUND: Serum thymidine kinase 1 (sTK1) activity is closely correlated with DNA synthesis. OBJECTIVES: Evaluate sTK1 activity as a biomarker for treatment response and early detection of relapse in dogs with lymphoma. ANIMALS: Ninety-seven client-owned dogs with naive or relapsed lymphoma and 23 healthy dogs. METHODS: Prospective study. Serum TK1 activity measured by refined ELISA-based method (DiviTum assay, Biovica International) before treatment, at clinical response, and every 4 weeks until relapse or last follow-up. RESULTS: Serum TK1 activity was ≤20 Du/L in 96% (22/23) of healthy dogs. Pretreatment sTK1 activity was >20 Du/L in 88% (85/97) dogs with lymphoma. At clinical response, sTK1 activity was significantly lower in dogs with complete (CR, n = 36) versus partial (PR, n = 29) response (P < .0001). Sensitivity (Se) and specificity (Sp) of sTK1 activity for detecting nonfully responders were 76% and 100%, respectively, with cutoff of 119.5 Du/L (AUC, 0.90; 95%-CI, 0.81-0.98; P < .0001). In dogs with CR, a 5-fold increase in sTK1 activity at a 4-week interval predicted relapse at the subsequent 4-week assessment with a Se 50% and Sp 94% (AUC, 0.72; 95%-CI, 0.55-0.90; P = .02). An increase of sTK1 activity (>2.7-fold value measured at clinical response) predicted relapse at subsequent 4-week assessment with a Se 61% and Sp 88% (AUC, 0.79; 95%-CI, 0.64-0.95; P = .004). CONCLUSIONS AND CLINICAL IMPORTANCE: Monitoring sTK1 activity could help to detect complete responders and early disease progression in dogs with lymphoma.

The use of octagam and gammanorm in immunodeficiency associated with hematological malignancies: a prospective study from 21 French hematology departments.

OBJECTIVE: Immunoglobulin replacement therapy (IgRT) is increasingly used in secondary immunodeficiency (SID) related to hematological malignancies (HM) to prevent infections. Study's objective was to document prospectively the efficacy and safety of IgRT in patients with HM-associated SID. METHODS: Non-interventional, prospective French longitudinal study. RESULTS: One-hundred and sixty patients starting IgRT for HM-associated SID (myeloma: 54 cases, chronic lymphoid leukemia: 54, aggressive non-Hodgkin B-cell lymphoma: 19, indolent non-Hodgkin B-cell lymphoma: 29, and Hodgkin disease: 4. entered an observational, prospective, longitudinal study and were followed-up for 8.7 ± 4.0 months. Seventeen patients died (five within the context of sepsis). Compared to baseline, IgRT increased serum immunoglobulin levels by 3.4 ± 2.4 g/L and decreased frequency and severity of infections. Treatment was discontinued in 9% of patients, stopped for futility in 31%, temporally interrupted in 8%, suspended during summertime in 14% and pursued without interruption in 38% of patients. CONCLUSION: Our data confirm the efficacy of IgRT in reducing the risk of infections in HM-associated SID therefore fulfilling physicians' main expectations. They also illustrate the heterogeneity of management policies within the community setting.

Rapid Push vs Pump-Infused Subcutaneous Immunoglobulin Treatment: a Randomized Crossover Study of Quality of Life in Primary Immunodeficiency Patients.

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.

Clinical phenotypes and survival of pre-capillary pulmonary hypertension in systemic sclerosis.

Pre-capillary pulmonary hypertension (PH) in systemic sclerosis (SSc) is a heterogeneous condition with an overall bad prognosis. The objective of this study was to identify and characterize homogeneous phenotypes by a cluster analysis in SSc patients with PH. Patients were identified from two prospective cohorts from the US and France. Clinical, pulmonary function, high-resolution chest tomography, hemodynamic and survival data were extracted. We performed cluster analysis using the k-means method and compared survival between clusters using Cox regression analysis. Cluster analysis of 200 patients identified four homogenous phenotypes. Cluster C1 included patients with mild to moderate risk pulmonary arterial hypertension (PAH) with limited or no interstitial lung disease (ILD) and low DLCO with a 3-year survival of 81.5% (95% CI: 71.4-88.2). C2 had pre-capillary PH due to extensive ILD and worse 3-year survival compared to C1 (adjusted hazard ratio [HR] 3.14; 95% CI 1.66-5.94; p = 0.0004). C3 had severe PAH and a trend towards worse survival (HR 2.53; 95% CI 0.99-6.49; p = 0.052). Cluster C4 and C1 were similar with no difference in survival (HR 0.65; 95% CI 0.19-2.27, p = 0.507) but with a higher DLCO in C4. PH in SSc can be characterized into distinct clusters that differ in prognosis.

Accuracy of the HumaSensplus point-of-care uric acid meter using capillary blood obtained by fingertip puncture.

BACKGROUND: The uric acid (UA) level in patients with gout is a key factor in disease management and is typically measured in the laboratory using plasma samples obtained after venous puncture. This study aimed to assess the reliability of immediate UA measurement with capillary blood samples obtained by fingertip puncture with the HumaSensplus point-of-care meter. METHODS: UA levels were measured using both the HumaSensplus meter in the clinic and the routine plasma UA method in the biochemistry laboratory of 238 consenting diabetic patients. HumaSensplus capillary and routine plasma UA measurements were compared by linear regression, Bland-Altman plots, intraclass correlation coefficient (ICC), and Lin's concordance coefficient. Values outside the dynamic range of the meter, low (LO) or high (HI), were analyzed separately. The best capillary UA thresholds for detecting hyperuricemia were determined by receiver operating characteristic (ROC) curves. The impact of potential confounding factors (demographic and biological parameters/treatments) was assessed. Capillary and routine plasma UA levels were compared to reference plasma UA measurements by liquid chromatography-mass spectrometry (LC-MS) for a subgroup of 67 patients. RESULTS: In total, 205 patients had capillary and routine plasma UA measurements available. ICC was 0.90 (95% confidence interval (CI) 0.87-0.92), Lin's coefficient was 0.91 (0.88-0.93), and the Bland-Altman plot showed good agreement over all tested values. Overall, 17 patients showed values outside the dynamic range. LO values were concordant with plasma values, but HI values were considered uninterpretable. Capillary UA thresholds of 299 and 340 µmol/l gave the best results for detecting hyperuricemia (corresponding to routine plasma UA thresholds of 300 and 360 µmol/l, respectively). No significant confounding factor was found among those tested, except for hematocrit; however, this had a negligible influence on the assay reliability. When capillary and routine plasma results were discordant, comparison with LC-MS measurements showed that plasma measurements had better concordance: capillary UA, ICC 0.84 (95% CI 0.75-0.90), Lin's coefficient 0.84 (0.77-0.91); plasma UA, ICC 0.96 (0.94-0.98), Lin's coefficient 0.96 (0.94-0.98). CONCLUSIONS: UA measurements with the HumaSensplus meter were reasonably comparable with those of the laboratory assay. The meter is easy to use and may be useful in the clinic and in epidemiologic studies.

A French observational study describing the use of human polyvalent immunoglobulins in hematological malignancy-associated secondary immunodeficiency.

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.

In-depth interviews of patients with primary immunodeficiency who have experienced pump and rapid push subcutaneous infusions of immunoglobulins reveal new insights on their preference and expectations.

PURPOSE: Patients with primary immunodeficiency (PID) often receive immunoglobulin replacement therapy (IgRT). Physicians and patients have the choice between various methods of administration. For subcutaneous immunoglobulin infusions, patients may use an automated pump (P) or push the plunger of a syringe (rapid push [RP]). P infusions are performed once a week and last around 1 hour. RP decreases the duration of administration, but requires more frequent infusions. PATIENTS AND METHODS: Eight out of 30 patients (coming from a single center) who had participated in the cross-over, randomized, open-label trial comparing P and RP participated in a focus group or underwent in-depth interviews. Patients had a long history of home-based subcutaneous immunoglobulin using P. The trial suggested that RP had slightly greater interference on daily life than P, but similar efficacy and better cost-effectiveness. When asked about the delivery method they had preferred, around one-third of patients pointed out RP rather than P. In-depth interviews may reveal unforeseen reasons for patients' preferences. RESULTS: Interviews underlined the complexity of the relationship that the patients maintain with their disease and IgRT. Even if they recognized the genetic nature of the disease and claimed PID was a part of them, patients tried not to be overwhelmed by the disease. IgRT by P was well integrated in patients' routine. By contrast, RP too frequently reminded the patients of their disease. In addition, some patients pointed out the difficulty of pushing the plunger due to the viscosity of the product. Coming back too frequently, RP was not perceived as time saving over a week. Long-lasting use of P could partly explain patients' reasonable reluctance to change to RP. CONCLUSION: In-depth interviews of PID patients highlighted unforeseen reasons for patients' preference that the physician needs to explore during the shared medical decision-making process.

Pulmonary Arterial Hypertension Associated With Systemic Lupus Erythematosus: Results From the French Pulmonary Hypertension Registry.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare complication of systemic lupus erythematosus (SLE). METHODS: We identified all patients with SLE and PAH (SLE-PAH) who were enrolled in the French Pulmonary Hypertension Registry with a diagnosis confirmed by right heart catheterization (RHC). A control group of 101 patients with SLE without known PAH was selected from SLE expert centers participating in the Pulmonary Hypertension Registry. Survival was estimated by the Kaplan-Meier method. Hazard ratios associated with potential predictors of death were estimated using Cox proportional hazard models. RESULTS: Of the 69 patients with SLE-PAH identified in the French Pulmonary Hypertension Registry, 51 were included in the study. They did not differ from the control group regarding age, sex, or duration of SLE at the time of the analysis but had a higher frequency of anti-SSA and anti-SSB antibodies. The delay between SLE diagnosis and PAH diagnosis was 4.9 years (range, 2.8-12.9) years. The 3- and 5-year overall survival rates were 89.4% (95% CI, 76.2%-96.5%) and 83.9% (95% CI, 68.8%-92.1%), respectively. The survival rate was significantly better in patients with anti-U1-RNP antibodies (P = .04). CONCLUSIONS: Patients with SLE-PAH have an overall 5-year survival rate of 83.9% after the PAH diagnosis. Anti-SSA/SSB antibodies may be a risk factor for PAH, and the presence of anti-U1-RNP antibodies appears to be a protective factor regarding survival.

Dyslipidemia, Alcohol Consumption, and Obesity as Main Factors Associated With Poor Control of Urate Levels in Patients Receiving Urate-Lowering Therapy.

OBJECTIVE: In real life, in a substantial proportion of gouty patients receiving urate-lowering therapy (ULT), urate levels are not maintained below the target of 6.0 mg/dl. We aimed to search for factors associated with poor control of serum uric acid (UA) levels in a large population of patients with gout receiving ULT. METHODS: This cross-sectional study involved adults with gout in primary care who were receiving ULT. Demographics, gout history, comorbidities, lifestyle, clinical factors, concomitant treatments, and laboratory data were compared in well-controlled gout (serum UA ≤6.0 mg/dl) versus poorly controlled gout (serum UA >6.0 mg/dl) on univariate and multivariate analyses. RESULTS: Among the 1,995 patients receiving ULT, only 445 (22.3%) had reached the target of 6.0 mg/dl serum UA. Such patients had a lower rate of gout flares within the previous year than patients without the target (mean ± SD 1.7 ± 1.4 versus 2.1 ± 1.4; P < 0.0001). The main factors associated with poor serum UA level control in multivariate analysis were low high-density lipoprotein cholesterol level (adjusted odds ratio [OR] 0.5 [95% confidence interval (95% CI) 0.26-0.96]; P = 0.04), high total cholesterol level (OR 1.83 [95% CI 1.29-2.60]; P = 0.0007), increased waist circumference (OR 1.55 [95% CI 1.11-2.13]; P = 0.008), and alcohol consumption (OR 1.52 [95% CI 1.15-2.00]; P = 0.003). CONCLUSION: Dyslipidemia, abdominal obesity, and alcohol consumption are the main factors associated with a poor response to ULT. Knowledge of these factors might help physicians identify cases of gout that may be less likely to achieve target urate level.

A cohort of French pediatric patients with primary immunodeficiencies: are patient preferences regarding replacement immunotherapy fulfilled in real-life conditions?

OBJECTIVE: To assess quality of life and satisfaction regarding immunoglobulin-replacement therapy (IgRT) treatment according to the route (intravenous Ig [IVIg] or subcutaneous Ig [SCIg]) and place of administration (home-based IgRT or hospital-based IgRT). SUBJECTS AND METHODS: Children 5-15 years old treated for primary immunodeficiency disease (PIDD) with IgRT for ≥3 months were included in a prospective, noninterventional cohort study and followed over 12 months. Quality of life was assessed with the Child Health Questionnaire - parent form (CHQ-PF)-50 questionnaire. Satisfaction with IgRT was measured with a three-dimensional scale (Life Quality Index [LQI] with three components: factor I [FI], treatment interference; FII, therapy-related problems; FIII, therapy settings). RESULTS: A total of 44 children (9.7±3.2 years old) receiving IgRT for a mean of 5.6±4.5 years (median 4.1 years) entered the study: 18 (40.9%) were receiving hospital-based IVIg, two (4.6%) were receiving home-based IVIg, and 24 (54.6%) were treated by home-based SCIg. LQI FIII was higher for home-based SCIg than for hospital-based IVIg (P=0.0003), but there was no difference for LQI FI or LQI FII. LQI FIII significantly improved in five patients who switched from IVIg to SCIg during the follow-up when compared to patients who pursued the same regimen (either IVIg or SCIg). No difference was found on CHQ-PF50 subscales, LQI FI, or LQI FII. CONCLUSION: Home-based SCIg gave higher satisfaction regarding therapy settings than hospital-based IVIg. No difference was found on other subscales of the LQI or CHQ-PF50 between hospital-based IVIG and home-based SCIG.

Controlling the digital ulcerative disease in systemic sclerosis is associated with improved hand function.

OBJECTIVES: Ischemic digital ulcers (DU) represent a major complication of systemic sclerosis (SSc). We investigated the impact of controlling the ulcerative disease on disability, pain, and quality of life in SSc patients receiving bosentan. METHODS: ECLIPSE (Study AC-052-517) is a 2-year prospective, multicenter, and observational study. Patients with SSc who experienced at least 1 DU in the previous year and received bosentan were included between October 2009 and March 2011. Disability scores [Cochin Hand Function Scale (CHFS) and Health Assessment Questionnaire Disability Index (HAQ-DI)], pain scores (visual analog scale), and quality-of-life scores (SF-36) were collected at inclusion and 1 year later (primary endpoint). A controlled ulcerative disease was defined by the absence of ongoing/new DU episode between inclusion and 1-year follow-up. RESULTS: Data were available at 1 year for 120 patients out of 190 included. During follow-up, 46 (38.3%) patients experienced a new DU episode. The number of DU per patient decreased from 1.4 ± 1.8 at inclusion to 0.6 ± 1.6 (p < 0.0001) at 1 year. Disability scores decreased from 1.0 ± 0.7 to 0.9 ± 0.7 (p = 0.04) for the HAQ-DI and from 29 ± 20 to 25 ± 20 (p = 0.005) for the CHFS; the pain score decreased from 4.3 ± 3.1 to 2.9 ± 2.8 (p < 0.0001). This improvement was attributed to patients with a controlled ulcerative disease (48.3%), who significantly improved HAQ-DI (p = 0.04), CHFS (p = 0.04), and pain score (p = 0.046). CONCLUSIONS: In patients with SSc, control of the ulcerative disease for 1 year was associated with significant attenuation of hand disability.
