RESUMEN

INTRODUCTION: Rheumatoid arthritis has a low level of medication adherence. Abroad, the community pharmacist has a positive impact on the patients' adherence in several chronic diseases. In France, community pharmacists' missions are developing with the implementation of pharmaceutical interviews. OBJECTIVE: To evaluate community pharmacists' perceptions on the interest and feasibility of pharmaceutical interviews targeting patients with rheumatoid arthritis. METHOD: Semi-structured interviews were conducted between August and October 2017, with pharmacists in the Auvergne-Rhône-Alpes region. The inductive analysis of the interview verbatim was realized by two independent persons. RESULTS: Fifteen community pharmacists highlighted barriers in recruiting patients for the interviews currently possible at the pharmacy, the complexity of the organization and the financing, a weakness of the hospital-to-community liaison. Nevertheless pharmacists were motivated to expand the service to other pathologies. Regarding rheumatoid arthritis, pharmacists would see them in the form of structured interviews preferentially at the pharmacy, in connection or even "prescribed" by physicians for optimal and multi-professional information sharing. Prior training and funding for these interviews should be considered to motivate pharmacists to this activity. CONCLUSION: This study allowed to discuss with community pharmacists their expectations and needs to widen the service of pharmaceutical interviews in the rheumatoid arthritis. These results will have to be taken into account to build a support interviews model for rheumatoid arthritis patients who can be integrated in their daily pharmaceutical activity.

RESUMEN

Articular cartilage is a specialized connective tissue containing chondrocytes embedded in a network of extracellular macromolecules such as type II collagen and presents poor capacity to self-repair. Autologous chondrocyte transplantation (ACT) is worldwide used for treatment of focal damage to articular cartilage. However, dedifferentiation of chondrocytes occurs during the long term culture necessary for mass cell production. The aim of this study was to investigate if addition of bone morphogenetic protein (BMP)-2, a strong inducer of chondrogenic expression, to human chondrocytes immediately after their isolation from cartilage, could help to maintain their chondrogenic phenotype in long-term culture conditions. Human articular chondrocytes were cultured according to the procedure used for ACT. Real-time PCR and Western blotting were performed to evaluate the cellular phenotype. Exogenous BMP-2 dramatically improves the chondrogenic character of knee articular chondrocytes amplified over two passages, as assessed by the BMP-2 stimulation on type II procollagen expression and synthesis. This study reveals that BMP-2 could potentially serve as a therapeutic agent for supporting the chondrogenic phenotype of human articular chondrocytes expanded in the conditions generally used for ACT.

RESUMEN

OBJECTIVE: Cartilage morphology displays sensitivity to change in osteoarthritis (OA) with quantitative MRI (qMRI). However, (sub)regional cartilage thickness change at 3.0 Tesla (T) has not been directly compared with radiographic progression of joint space narrowing in OA participants and non-arthritic controls. METHODS: A total of 145 women were imaged at 7 clinical centres: 86 were non-obese and asymptomatic without radiographic OA and 55 were obese with symptomatic and radiographic OA (27 Kellgren-Lawrence grade (KLG)2 and 28 KLG3). Lyon-Schuss (LS) and fixed flexion (FF) radiographs were obtained at baseline, 12 and 24 months, and coronal spoiled gradient echo MRI sequences at 3.0 T at baseline, 6, 12 and 24 months. (Sub)regional, femorotibial cartilage thickness and minimum joint space width (mJSW) in the medial femorotibial compartment were measured and the standardised response means (SRMs) determined. RESULTS: At 6 months, qMRI demonstrated a -3.7% "annualised" change in cartilage thickness (SRM -0.33) in the central medial femorotibial compartment (cMFTC) of KLG3 subjects, but no change in KLG2 subjects. The SRM for mJSW in 12-month LS/FF radiographs of KLG3 participants was -0.68/-0.13 and at 24 months was -0.62/-0.20. The SRM for cMFTC changes measured with qMRI was -0.32 (12 months; -2.0%) and -0.48 (24 months; -2.2%), respectively. CONCLUSIONS: qMRI and LS radiography detected significant change in KLG3 participants at high risk of progression, but not in KLG2 participants, and only small changes in controls. At 12 and 24 months, LS displayed greater, and FF less, sensitivity to change in KLG3 participants than qMRI.

RESUMEN

BACKGROUND: Measurement of radiographic joint space width (JSW) and of joint space narrowing (JSN) is the currently recommended method for assessment of anatomical severity and structural progression of osteoarthritis (OA), respectively. A standard radiographic view of the pelvis is commonly used for measurement of hip OA but other views are available. OBJECTIVES: To evaluate the inter-intra reader reproducibility and the sensitivity to change of a new automated method of measurement of the hip JSW and to assess which radiographic view [pelvis anteroposterior (AP) view, hip AP view, hip oblique view] provides the greatest accuracy for JSW and JSN measurements. MATERIAL AND METHODS: An AP pelvis radiograph, an AP radiograph centered on the target hip (AP hip) and an oblique view were performed at baseline (M0) and 3 years later (M36) in 50 hip OA patients. Two readers, blinded to each other's results and time sequence, measured twice, at a minimum 15 day interval, the six radiographs of each patient, using a novel version of a previously validated software program whose edge-based algorithm automatically detects the joint space contours. Inter-observer cross-sectional (M0+M36) and longitudinal (M0-M36) reproducibility of JSW measurement was assessed by the intra-class correlation coefficient (ICC) and the Bland-Altman method. Sensitivity to change was estimated by the standardized response mean (SRM). An ANOVA was used to analyze differences related to the observer and the view. RESULTS: Intra-observer reproducibility: For JSW measurement, the ICC value, for observers 1 and 2 respectively, were 0.92 and 0.83 for the pelvic view, 0.96 and 0.88 for the hip AP view, and 0.90 and 0.86 for the oblique view. For JSN, ICC was 0.94 and 0.82 for the pelvic view, 0.97 and 0.78 for the hip AP view, and 0.95 and 0.86 for the oblique view. Inter-observer reproducibility: For JSW measurement, ICC was 0.87 for the pelvic view, 0.98 for the hip AP view, and 0.87 for the oblique view. The mean inter-observer difference (SD) was 0.0 (0.31), -0.01 (0.15) and -0.04 (0.4)mm for pelvic, AP and oblique views respectively. For JSN, ICC was 0.91 for the pelvic view, 0.93 for the hip AP view, and 0.90 for the oblique view. Sensitivity to change: SRM values were 0.61 (observer 1) and 0.65 (observer 2) for the pelvic view, 0.68 and 0.75, respectively, for the hip AP view, 0.64 and 0.66, respectively, for the oblique view. JSN did not vary significantly with the observer and the view. In 27% of cases intervention by the observer was necessary to correct the computer's identification of the acetabular edge in the area of interest. CONCLUSION: Computer measurement of the radiographic hip joint space provided good intra- and inter-observer reproducibility and good sensitivity to change. However, it was necessary for the observer to intervene frequently to select the area of interest and adjust detection of the bone edge. The hip AP view performed better than the pelvis and oblique views, but not significantly so.

RESUMEN

OBJECTIVE: To identify subregional differences in femorotibial cartilage morphology between healthy controls and women with different grades of radiographic knee osteoarthritis (OA). DESIGN: 158 women aged > or =40 years were studied. Weight-bearing extended anterior-posterior (AP) and Lyon schuss radiographs were obtained and the Kellgren Lawrence grade (KLG) determined. 97 women had a body mass index (BMI)< or =28, no symptoms, and were AP KLG0. 61 women had a BMI> or =30, symptoms in the target knee, and mild (KLG2=31) to moderate (KLG3=30) medial femorotibial radiographic OA in the AP views. Coronal spoiled gradient echo water excitation sequences were acquired at 3.0 Tesla. Total plate and regional measures of cartilage morphology of the weight-bearing femorotibial joint were quantified. RESULTS: KLG2 participants displayed, on average, thicker cartilage than healthy controls in the medial femorotibial compartment (particularly anterior subregion of the medial tibia (MT) and peripheral [external, internal] subregions of the medial femur), and in the lateral femur. KLG3 participants displayed significantly thinner cartilage than KLG0 participants in the medial weight-bearing femur (central subregion), in the external subregion of the MT, and in the internal subregion of the lateral tibia. These differences were generally unaffected when possible effects of demographic covariates were considered. CONCLUSIONS: The results indicate that in femorotibial OA regional cartilage thickening and thinning may occur, dependent on the (radiographic) disease status of the joint. These changes appear to display a heterogeneous spatial pattern, where certain subregions are more strongly affected than others.

RESUMEN

AIM OF THE STUDY: Cartilage has a limited capacity for healing after trauma. Autologous chondrocyte implantation is widely used for the treatment of patients with focal damage to articular cartilage. Chondrocytes are isolated from biopsy specimen, cultured in monolayers on plastic then transplanted over the cartilage defect. However, chondrocyte amplification on plastic triggers their dedifferentiation. This phenomenon is characterized by loss of expression of type II collagen, the most abundant cartilage protein. The challenge for autologous chondrocyte implantation is to provide patients with well-differentiated cells. The aim of the present study was to test the capability of bone morphogenetic protein (BMP)-2 to promote redifferentiation of human chondrocytes after their expansion on plastic. MATERIALS AND METHODS: Chondrocytes extracted from nasal cartilage obtained after septoplasty were serially cultured in monolayers. After one, two or three passages, BMP-2 was added to the culture medium. The cellular phenotype was characterized at the gene level by using RT-PCR. The expression of genes coding for type II procollagen with the ratio of IIB/IIA forms, aggrecan, Sox9, osteocalcin and type I procollagen was monitored. RESULTS: Our results show that BMP-2 can stimulate chondrogenic expression of the chondrocytes amplified on plastic, without inducing osteogenic expression. However, this stimulatory effect decreases with the number of passages. CONCLUSION: The efficiency of autologous chondrocyte implantation could be improved by using chondrocytes treated with BMP-2 during their in vitro preparation.

RESUMEN

OBJECTIVE: The Lyon Schuss (LS) and fixed flexion (FF) views of the knee are superior to a conventional standing anteroposterior view in evaluating joint space narrowing (JSN) in osteoarthritis (OA). Both position the knee identically but only the LS aligns the medial tibial plateau (MTP) with the x-ray beam fluoroscopically. The present study provides the first head-to-head comparison of the LS and FF views. METHODS: At baseline and 12 months, 62 OA and 99 control knees were imaged twice on the same day with LS and FF views. Minimum joint space width (mJSW) was measured by computer and MTP alignment was assessed from the distance between anterior and posterior margins of the MTP (intermargin distance, IMD). Reproducibility of measurements of mJSW and sensitivity to change were evaluated. RESULTS: In normal knees, JSW did not vary over 12 months with either view. In OA knees, 12-month mJSN was 0.22 (0.43) mm with the LS view and -0.01 (0.46) mm with the FF view (p = 0.0002 and p = 0.92, respectively). Mean IMD was only half as large in LS as in FF views (0.9 (0.5) mm vs 1.9 (1.2) mm, p<0.0001). CONCLUSIONS: LS and FF radiographs offer similar reproducibility in JSW measurement. However, presumably due to its superiority in aligning the MTP, the LS view is much more sensitive to JSN in OA knees.

RESUMEN

BACKGROUND: Cartilage destruction in osteoarthritis (OA) involves excessive degradation and increased synthesis of cartilage matrix macromolecules including type II collagen and proteoglycans. Cartilage biomarkers exist for the measurement of cartilage matrix turnover and may reveal differences in patients with OA. OBJECTIVE: To determine whether there are detectable differences in and relationships between biomarkers of type II collagen (CII) degradation (C2C, C1, 2C) and synthesis (CP II) in patients with only hip OA (OHOA) and those suffering from multiple sites OA (MSOA). PATIENTS AND METHODS: Fifty-six patients classified as MSOA or OHOA. Minimum hip joint space width (Min JSW) measured by computer from standard radiographs. Serum measurement of CII synthesis C-propeptide (CPII) and cleavage of type II (C2C) and types I and II (C1, 2C) collagens. Aggrecan metabolism was assessed by serum CS 846 assay. Step to step logistic regression to determine the effect of the quantitative data on the assignment to each subgroup. RESULTS: Twenty-four subjects were classified with MSOA. Among the 32 OHAO patients, 15 had bilateral hip OA and 17 had unilateral hip OA. The latter were classified with "Isolated hip OA" (IHOA). CPII levels were significantly lower in patients with MSOA than in those with OHOA (99.9+/-50.3ng/mL versus 141.9+/-81.2ng/mL, p=0.04. OR= 0.18 for CPII >120 ng/mL, p<0.005). C2C levels were also lower in MSOA (9.7+/-2.3ng/mL) versus OHOA (11.4+/-3.2ng/mL, p=0.03. OR= 0.26 for C2C >10 ng/mL, p=0.02). There was an inverse correlation between min JSW and C2C only in patients with IHOA (r=0.50, p= 0.02). CONCLUSION: Hip OA, in patients with MSOA, might be related to alteration in CII metabolism which may result in a deficient type II collagen repair process. The significant relationship between C2C and JSW in IHOA suggests that this marker is of value in assessing cartilage degradation patients with involvement of a single joint.

RESUMEN

OBJECTIVE: Lack of osteophytes (atrophic form) has been shown to be a factor in the severity of hip osteoarthritis (OA). The aim of this study was to determine the epidemiological, radiological and biological differences between the hypertrophic and atrophic forms of hip osteoarthritis. METHODS: 25 patients with symptomatic hip OA (ACR criteria) and classified as having an atrophic form of OA based on the lack of osteophytes on standard radiograph of the pelvis, were matched for joint space width with 25 subjects with evidence of the hypertrophic form of hip OA. OA radiological severity was assessed using a scoring system and by computer measurement of the joint space width. Angles of hip dysplasia were measured. Serum hyaluronic acid, cartilage oligomeric matrix protein, collagenase, Type I procollagen, C-terminal crosslinking telopeptide of type I collagen and tissue inhibitor of métalloproteases-1 were assayed by immunoassay and C-reactive protein by ultrasensitive immunonephelemetry. Statistical analysis was performed using logistic regression, taking into account age, sex, body mass index, and bilaterality. RESULTS: Compared to hypertrophic OA, atrophic OA affected chiefly elderly women and was characterized by a smaller centre-edge angle and diffuse superior femoral head migration. It was less frequently bilateral. No statistically significant difference was found in the biological data between the two groups. CONCLUSION: An atrophic bone response in hip OA occurs chiefly in women and is associated with poor coverage of the femoral head. Serum biomarkers able to demonstrate differences between the atrophic and hypertrophic patterns of OA are lacking.

RESUMEN

STUDY DESIGN: Prospective study of phospholipase A2 activity in the serum and intervertebral discs of patients undergoing surgery for sciatica due to disc herniation. OBJECTIVES: To determine correlations between herniated disc phospholipase A2 and clinical, radiographic, and anatomic signs of common sciatica; to evaluate serum phospholipase A2 activity as a marker of disc phospholipase A2; and to investigate the in vivo effect of piroxicam on disc phospholipase A2. SUMMARY OF BACKGROUND DATA: Several studies suggest disc inflammation as a mechanism of sciatica due to disc herniation, and phospholipase A2 emerges as a key enzyme of cartilage and disc tissues. METHODS: Phospholipase A2 activity was determined, using the degradation of a specific substrate, in the serum and discs of 31 patients (14 treated with acetaminophen and 17 treated with piroxicam) undergoing surgery for sciatica due to lumbar disc herniation. Visual analog scale for pain, Dallas Pain Questionnaire, Lasègue's sign, radiographic stage of degeneration of the herniated disc, volume of disc herniation shown by computed tomography, and surgical findings were recorded. RESULTS: Disc phospholipase A2 activity was independent of the patient's age or sex, the radiologic stage of disc degeneration, and the volume of the herniation, and showed no significant correlation with Lasègue's sign or pain measured on a visual analog scale. The correlation between disc phospholipase A2 and the Dallas category of items measuring the impact of pain on daily activities approached the level of significance (P = 0.07). Disc phospholipase A2 activity was significantly higher in cases of sequestrated discs than in other herniations. Disc phospholipase A2 was significantly correlated with serum phospholipase A2, and was significantly lower in patients treated with piroxicam than in those treated with acetaminophen. CONCLUSIONS: Disc phospholipase A2 is thought to participate in the physiopathology of sciatica and to bemodulated by nonsteroidal anti-inflammatory drug therapy. Serum phospholipase A2 is suggested as a biologic marker of disc inflammation in patients with sciatica.

RESUMEN

Atherosclerosis results from a multifactorial process. For that reason, primary prevention of cardiovascular diseases requires several measures that should exhibit antiatherogenic, antithrombotic, antioxidative and antihypertensive properties. Two types of therapeutic strategies can be individualized. Nutritional interventions are the first line measures for population wide primary prevention in subjects at low risk of developing atheroscleric diseases. In high risk individuals who have either one major risk factor (LDL cholesterol above 190 mg/dL) or several additional risk factors, dietary measures must be frequently combined with drug treatments. However, the cost-effectiveness ratio should be weighed prior to any treatment especially with statins. Dietary measures consist to reduce caloric intakes in overweight subjects, or more generally to adopt eating patterns which correspond to the following recommendations: (i) proteins = 15% of total calories; (ii) saturated and polyunsatured fats = 10% each; (iii) carbohydrates plus monounsaturated fats = 65%. Such dietary instructions permit individual dietary changes, just by adjusting the carbohydrates/monounsaturates balance, the sum of both nutrients remaining in all cases equal to two-thirds to total calories. Drug treatments are only indicated after secondary dietary failure. They are generally based on the use of statins since the efficacy of these treatments has been clearly established by such preventive trials as the WOSCOP Study, provided that the therapeutic interventions result in significant reduction of LDL cholesterol levels over several years. Antiplatelet agents (aspirin), antihypertensive therapies, antioxidant supplementations with vitamins E or C are also recommended in some individuals for completing the beneficial effects of the above mentioned measures.

RESUMEN

Primary systemic amyloidosis rarely affects the walls of small and medium-sized vessels. We report a case of primary AL amyloidosis masquerading as giant cell arteritis at the onset of the disease, revealed by the temporal arteritis biopsy, and successfully treated by corticotherapy for three years. Histology of temporal arteritis confirms the diagnosis of amyloidosis (characteristic birefringence with Congo red). We discuss in this case the diagnosis of primary amyloidosis revealed by Horton disease, or the coincidental association of these two diseases.

RESUMEN

In this prospective study, serum hyaluronate (SH) was assayed using a radiometric method (Pharmacia) in 73 osteoarthritis patients and 39 controls. All assays were performed between 8 h 00 and 9 h 00 a.m. because SH levels exhibit circadian variations. SH levels were significantly higher in patients with osteoarthritis than in controls (92 +/- 66 micrograms/l and 39 +/- 21 micrograms/l, respectively, p = 0.0001). Among 50 patients with osteoarthritis, including 29 with knee involvement and 21 with hip involvement, SH levels were not correlated with morning stiffness, duration of symptoms, Lequesne's algofunctional index, erythrocyte sedimentation rate, C-reactive protein, severity of roentgenographic changes in the affected knee or hip, disease extension, or severity. The lack of any relationship between changes in SH levels and Lequesne's is index values in 25 patients or between SH levels and joint space narrowing evaluated retrospectively in 16 patients, as well as the prompt return to high SH levels after arthroplasty and synovectomy in 14 patients with hip joint osteoarthritis, suggest that this potential marker is not useful for monitoring osteoarthritis in a single joint.

RESUMEN

Joint surface area (JSA) and mean joint space width (MJSW) at the hip were measured using a ICMS-Techline computer program to analyze digitalised frontal weight-bearing roentgenograms of the pelvis. With this technique, the portion of joint space studied is always the same in a given patient and is enclosed within an acute ECS angle whose apex C is the center of the head of the femur and whose ends E and S are the lateral rim of the acetabulum and the highest point of the homolateral sacral wing respectively. ECS varies across individuals but remains constant in a given hip. Twenty hips were included in the first part of the study. For each hip, three roentgenograms were taken at five-minute intervals by three different radiologists who used their own constants (settings, position of the subject). JSA and MJSW are determined five times on each film by two different observers who had no information on the films under study. The interobserver coefficient of variation (CV) was 4.7% for JSA and 3.3% for MJSW. Intra-observer CVs were 2.97 and 3.54% for MJSW and 4.32% and 5.13% for JSA. There was a very close correlation between MJSW and JSA (r = 0.87, p < 0.0001). MJSW was then determined for roentgenograms of 30 hips with osteoarthritis. Results were compared with the values obtained using Lequesne's method of joint space measurement at the site of maximum narrowing. Measurements were performed in a double-blind fashion by two observers. The correlation coefficient was r = 0.89 (p < 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Serum phospholipase A2 activity in 67 osteoarthritis patients and 17 controls was determined using a radiolabeled specific substrate. Serum phospholipase A2 activity was significantly higher in osteoarthritis patients (115 +/- 73.6 dpm/h/ml) than in controls (45 +/- 25 dpm/h/ml) (p = 0.002). In 41 osteoarthritis patients, serum phospholipase A2 activity was unrelated to age, time since onset of osteoarthritis symptoms, duration of morning stiffness, Lequesne's index, roentgenographic stage of osteoarthritis, number of joints with osteoarthritis, erythrocyte sedimentation rate, or serum C-reactive protein levels. In 12 osteoarthritis patients who were evaluated twice at a mean interval of 46 days, changes in serum phospholipase A2 activity were unrelated to changes in Lequesne's index. Blind evaluation of long-term joint space loss was performed in 14 patients; serum phospholipase A2 activity increased only in those patients with progressive joint space loss, but the difference was not statistically significant as compared with the controls. These data suggest that serum phospholipase A2 activity is not useful in practice as a marker for osteoarthritis.

RESUMEN

BACKGROUND: Autologous chondrocyte implantation (ACI) was introduced in 1987 in Sweden by Brittberg and Peterson for the treatment of severe chondral defects of the knee. Here, our objective was to evaluate mid-term outcomes of ACI in young athletic patients with deep chondral defects of the knee after trauma. HYPOTHESIS: ACI is effective in filling full-thickness chondral defects of the knee. PATIENTS AND METHODS: We prospectively monitored 14 patients, with International Cartilage Repair Society grade III or IV lesions, who underwent ACI between 2001 and 2006. Standard evaluation measurements were used. Mean age at surgery was 37.7 years (range, 30-45). A history of surgery on the same knee was noted in ten (67%) patients. The defect was on the medial femoral condyle in 11 patients, lateral femoral condyle in two patients, and both femoral condyles in one patient. Mean defect surface area after debridement was 2.1cm(2) (1-6.3). RESULTS: After a mean follow-up of six years, improvements were noted in 12 (86%) patients, with an International Knee Documentation Committee (IKDC) score increase from 40 (27.6-65.5) to 60.2 (35.6-89.6) (P=0.003) and a Brittberg-Perterson score decrease from 54.4 (11.8-98.2) to 32.9 (0-83.9) (P=0.02), between the preoperative assessment and last follow-up. The visual analogic scale pain score decreased from 66.3 (44-89) to 23.2 (0-77) (P=0.0006). In two (14%) patients, no improvements were detectable at last follow-up. The remaining 12 patients were satisfied and able to resume sporting activities, albeit at a less strenuous level. Two ACI-specific complications occurred, namely, periosteal hypertrophy treated with debridement in one patient and transplant delamination in another. DISCUSSION: Our findings are consistent with previous reports but cover a longer follow-up period. Although the outcomes are promising, longer follow-ups are needed to confirm the long-term effectiveness of ACI. LEVEL OF EVIDENCE: IV, prospective therapeutic study.
