Disease activity score for still's disease.

OBJECTIVE: To develop the Still's Disease Activity Score (SDAS). METHODS: We used data from the prospective adult-onset Still's disease cohort study and evaluated the disease activity. An expert group selected the most frequent, reproducible, and objective variables significantly modified in statistical analysis when comparing patients in the active group and in the remission group. These criteria were weighted to design the Still's Disease Activity Score (SDAS). The Delphi method was used to appreciate the level of disease activity. Total SDAS was calculated for each patient and compared to final consensus experts. RESULTS: At the diagnosis, all patients had an active disease (n = 80), while 48 patients were in remission at 6 months. The SDAS criteria were weighted as follows: fever ≥ 38.5 °C (1 point), rash (1 point), joint involvement (arthralgia: 1 point, swollen joints count "SJC": 1-3 SJC: 2 points, ≥ 4 SJC: 3 points), physician global assessment VAS ≥ 5/10 or a raise in physician VAS ≥ 2/10 (3 points), patient VAS ≥ 5 or a raise in patient VAS ≥ 2/10 (1 point), and CRP (> 10 mg/l: 1 point, ≥ 100 mg/l: 2 points). At 6 months, the consensus was achieved for 76 (95%) patients with 40 in remission (0-1 point), 8 in low disease activity (2-3 points), 16 in moderate disease activity (4-7 points), and 12 in severe disease activity (≥ 8 points). CONCLUSION: The Still's Disease Activity Score is a valid and sensitive assessment of the disease activity and the therapeutic response in Still's disease, despite its heterogeneous manifestations and patterns with systemic and articular forms. Key Points • The Still's Disease Activity Score (SDAS) is a good simple tool to assess the activity of the disease in a stable state for a week. • The SDAS is developed specifically for Still's disease without the need for an application or a calculator to calculate SDAS in routine clinical practice. • SDAS is a composite score classifying the disease activity in remission, low disease activity, moderate disease activity, and severe disease activity despite its heterogeneous patterns (systemic and articular forms). • The SDAS is a valid, reliable, and sensitive score and can be useful to guide the therapeutic strategy in clinical practice and in research.

Proposal of a new diagnostic algorithm for adult-onset Still's disease.

OBJECTIVE: This study was performed to develop a new diagnostic algorithm for adult-onset Still's disease (AOSD). METHODS: We conducted a multicenter prospective nationwide case-control study in tertiary Internal Medicine, Rheumatology, and Infectious Diseases departments, to include successively patients with suspected AOSD based on the presence of two or more major criteria of Yamaguchi and/or Fautrel classifications. Patients were classified as AOSD or controls according to a predefined procedure. A receiving operating characteristic curve was used to determine the best cutoff value of the points-based score for disease classification. A diagnostic algorithm was developed to help the physician in the diagnostic approach. RESULTS: A total of 160 patients were included, 80 patients with AOSD and 60 controls with different diagnoses. Twenty patients with incomplete data were excluded. In the multivariate analysis, 6 items remained independently associated with AOSD diagnosis: typical rash (OR: 24.01, 3 points), fever ≥ 39 °C (OR: 17.34, 3 points), pharyngitis (OR: 10.23, 2 points), arthritis (OR: 9.01, 2 points), NLR ≥ 4 (OR: 11.10, 2 points), and glycosylated ferritin ≤ 20% (OR: 1.59, 1 point). AOSD should be considered if the patient satisfies 7 points with a sensitivity of 92.5%, specificity of 93.3%, and accuracy of 92.8% (area under the curve (AUC): 0.97 [95% CI: 0.94-0.99]). The present points-based score was more accurate and sensitive than the Yamaguchi classification (78.8%, 92.5%, p = 0.01) and Fautrel classification (76.3%, 92.5%, p = 0.004). A typical rash associated with a points-based score ≥ 7 points leads to a very likely disease. CONCLUSION: The proposed new algorithm could be a good diagnostic tool for adult-onset Still's disease in clinical practice and research. Key Points • A diagnostic algorithm was performed to help the physician in the diagnostic approach of AOSD. • The points-based score included in this algorithm had a high sensitivity and accuracy. • This diagnostic algorithm can be useful in the clinical research.

Validation of the neutrophil-to-lymphocyte ratio as a new simple biomarker of adult onset Still's disease: A STROBE-Compliant prospective observational study.

This study was performed to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of adult onset Still disease (AOSD) and its performance to improve the sensitivity of the classifications criteria (Yamaguchi and Fautrel Classifications). We conducted a multicenter prospective nationwide case-control study in Internal medicine, Rheumatology and Infectious disease departments, to include successively patients with suspected AOSD (2 or more major criteria of Yamaguchi or Fautrel classifications). All clinical and biological features were collected in a consensual and standardized clinical assessment at baseline and during follow-up. A receiving operating characteristic (ROC) curve was used to reassess the cutoff value of NLR. After determination of the cutoff value for NLR by ROC curve, 2 composite sets (Yamaguchi classification + NLR as a major criterion and Fautrel classification + NLR as a major criterion) were performed and evaluated. One hundred sixty patients were included, 80 patients with AOSD and 60 controls with different diagnoses. Twenty patients with incomplete data were excluded. The cutoff value for NLR equals 4 (area under the curve, AUC: 0.82). The NLR was ≥ 4 in 93.7% (75/80) of AOSD patients with a sensitivity of 93.8% and specificity of 61.7%. The association of NLR as a major criterion with the classification of Yamaguchi or Fautrel improved their sensitivity, respectively for Fautrel (76.3% to 92.5%, P = .004) and Yamaguchi (78.8% to 90%, P = .05). This study validates the NLR as a good simple biomarker of AOSD with a cutoff value of 4 and high sensitivity (93.8%). The addition of NLR (NLR ≥ 4) as a major criterion to the classifications (Yamaguchi and Fautrel) improved significantly their sensitivity and accuracy.

Throwing a spotlight on under-recognized manifestations of Gaucher disease: Pulmonary involvement, lymphadenopathy and Gaucheroma.

BACKGROUND: Gaucher disease (GD) is a rare lysosomal storage disorder classically subdivided into type 1 (non-neuronopathic) GD, and types 2 and 3 (neuronopathic) GD. It is typically characterized by clinical manifestations including anemia, thrombocytopenia, hepatosplenomegaly, bone lesions, and (in more severe forms) neurological impairment. However, less-commonly reported and often under-recognized manifestations exist, which potentially have a significant impact on patient outcomes. Greater efforts are needed to understand, recognize, and manage these manifestations. OBJECTIVES: This review provides a synthesis of published information about three under-recognized GD manifestations (pulmonary involvement, lymphadenopathy, and Gaucheroma) and recommends diagnostic, management, and treatment strategies based on the available literature and author experience. The authors aim to raise awareness about these serious, progressive, and sometimes life-threatening conditions, which are often diagnosed late in life. CONCLUSIONS: Little is known about the incidence, pathophysiology, prognostic factors, and optimal management of pulmonary involvement, lymphadenopathy, and Gaucheroma in patients with GD. Enzyme replacement therapy (ERT) has shown limited efficacy for the prevention and treatment of these manifestations. More research is needed to evaluate the potential effect of substrate reduction therapy (SRT) with glucosylceramide synthase (GCS) inhibitors, and to develop additional approaches to treat these GD manifestations. Improvements in data collection registries and international data-sharing are required to better understand the impact of these manifestations on GD patients, help develop effective management strategies, and, ultimately, improve patient outcomes.

Achievement of low-density lipoprotein cholesterol goals in 18 countries outside Western Europe: The International ChoLesterol management Practice Study (ICLPS).

Background Little is known about the achievement of low density lipoprotein cholesterol (LDL-C) targets in patients at cardiovascular risk receiving stable lipid-lowering therapy (LLT) in countries outside Western Europe. Methods This cross-sectional observational study was conducted in 452 centres (August 2015-August 2016) in 18 countries in Eastern Europe, Asia, Africa, the Middle East and Latin America. Patients ( n = 9049) treated for ≥3 months with any LLT and in whom an LDL-C measurement on stable LLT was available within the previous 12 months were included. Results The mean±SD age was 60.2 ± 11.7 years, 55.0% of patients were men and the mean ± SD LDL-C value on LLT was 2.6 ± 1.3 mmol/L (101.0 ± 49.2 mg/dL). At enrolment, 97.9% of patients were receiving a statin (25.3% on high intensity treatment). Only 32.1% of the very high risk patients versus 51.9% of the high risk and 55.7% of the moderate risk patients achieved their LDL-C goals. On multivariable analysis, factors independently associated with not achieving LDL-C goals were no (versus lower dose) statin therapy, a higher (versus lower) dose of statin, statin intolerance, overweight and obesity, female sex, neurocognitive disorders, level of cardiovascular risk, LDL-C value unknown at diagnosis, high blood pressure and current smoking. Diabetes was associated with a lower risk of not achieving LDL-C goals. Conclusions These observational data suggest that the achievement of LDL-C goals is suboptimal in selected countries outside Western Europe. Efforts are needed to improve the management of patients using combination therapy and/or more intensive LLTs.

[Preliminary evaluation of the antioxidant trace elements in an Algerian patient with type 2 diabetes: special role of manganese and chromium]. / Évaluation primaire du statut antioxydant oligominéral chez le patient diabétique de type 2 algérien : intérêt particulier du manganèse et du chrome.

In type 2 diabetes, the relationship between antioxidants and insuline-like trace elements is very complex during oxidative stress, being mediated by hyperglycemia, dyslipidemia and inflammation. We investigated the antioxidant status, particularly Mn and Cr on the diabetes metabolic control, and their interaction with the metabolic syndrome (MS) parameters. The study was undertaken on 278 Algerian diabetic subjects who were divided in 2 groups according to glycated hemoglobin (HbA(1c)) <7% or >7% value, attesting for a good or poor metabolic control of diabetes, respectively. The MS was defined according to NCEP-ATPIII. Insulin resistance was evaluated by HOMA-IR model. The plasma manganese concentrations was significantly increased in both diabetics groups, independently of metabolic control. However, chromium (Cr) seems to play a determinant action in metabolic control, as shown by better values of insulin resistance (HOMA-IR) and HbA(1c). The selenium status was positively correlated with glutathion peroxidase activity. Copper and zinc plasma levels in the diabetic patients were similar to those of control subjects. In conclusion, our results suggest that Mn play a crucial role in antioxidant capacity and we hypothesize that antioxidant defense is preserved in the cytosol (superoxide dismutase Cu/Zn -SOD), whereas it is impaired in mitochondria (Mn-SOD), which makes this cell organelle a true therapeutic target in diabetes.
