Background:The problem of infectious complications in patients receiving bDMARDs deserves special attention. Serious infectious adverse events (SIAE) are a most important issue. To develop measures for their prevention it is necessary to know the predisposing factors.Objectives:to detect predictors of serious infections among patients with rheumatoid arthritis receiving targeted therapyMethods:The study includes patients with rheumatoid arthritis from the Moscow Unified Arthritis Registry (MUAR), receiving treatment with biologics or tofacitinib. Search for predictors was carried out in two steps. At first step we selected patient related predictors (confounders) that significantly correlate with risk of SIAE. At the second step in the Cox risk regression model by forward stepwise selection were identified independent significant predictors of risk. which demonstrated significant correlation with development of serious infections. Then data about the treatment was added to the generated model: used targeted DMARDs, doses of glucocorticoids (GC), doses of methotrexate (MTX).Results:Analysis includes 1052 treatment events in 772 patients. There were 44 serious infections. The mean age was 57,1 ± 12,8 years. The mean observation time – 5.3 years. Independent patient related predictors of SIAE risk were the age RR - 1.12 per year (CI: 1.06-1.19), the age of onset disease RR - 0.94 per year (CI: 0.90-0.98), the year of inclusion in the registry RR - 0.64 per year (CI: 0.49-0.85). The dose of MTX and the doses of GC positively correlate with SIAE risk. RR for MTX is 1.05 per mg (CI: 1.005-1.109), RR for GC - 1.11 per mg (CI: 1.004-1.236).Used targeted DMARD didn’t show any significant correlation with SIAE risk.Conclusion:Higher doses of methotrexate and glucocorticoids are independent significant predictors of serious infections in RA patients receiving targeted DMARDs.Disclosure of Interests:Ekaterina Koltsova: None declared, Galina Lukina Speakers bureau: Novartis, Pfizer, UCB, Abbvie, Biocad, MSD, Roche, Evgeniya Shmidt Speakers bureau: MSD, Novartis, Pfizer, Karine Lytkina Speakers bureau: Novartis, Eli Lilly, Pfizer, UCB, Abbvie, Biocad, MSD, Jonson&Jonson, Evgeniy Zhilyaev Speakers bureau: Novartis, UCB, Pfizer, Biocad, Abbvie, MSD, Roche

Objective.To compare clinical characteristics and treatment between simultaneously investigated Sudanese and Swedish outpatients with rheumatoid arthritis (RA).Methods.Outpatients with RA from Sudan (n = 281) and Sweden (n = 542) diagnosed according to the 1987 American College of Rheumatology criteria were recruited between December 2008 and September 2010 and compared concerning clinical presentation, treatment, and laboratory findings, including immunoglobulin M with rheumatoid factor (IgM-RF).Results.Sudanese patients had lower inclusion age (median 49 vs 68 yrs), disease duration (48 vs 107 mos), and disease onset age (43 vs 56 yrs) as compared with Swedish patients (p < 0.0001 for all). When stratified concerning the age of inclusion, Swedish patients between 41–50 years had, however, a significantly lower age of onset, with a similar trend for all age groups above 30 years. The female preponderance was higher among Sudanese patients (89.3% vs 72.5%, p < 0.0001), and smoking was nonexistent among Sudanese female patients (p < 0.0001). Erythrocyte sedimentation rate levels and number of tender joints were significantly higher among Sudanese patients. The proportion of IgM-RF positivity was lower among Sudanese patients with RA (52.4% vs 75.5%, p < 0.0001). Higher proportions of Sudanese patients with RA were treated with methotrexate (MTX) and disease-modifying antirheumatic drug combinations, but none of them used biologics. Sudanese patients used lower doses of MTX and sulfasalazine (p < 0.0001) and higher doses of prednisolone (p < 0.0001) than Swedish patients.Conclusion.Sudanese patients with RA have significantly higher disease activity and are often IgM-RF–seronegative. Together with reports from Uganda and Cameroon, our data indicate a cluster of highly active and often seronegative RA in central Africa.

Immunomodulatory therapy for rheumatoid arthritis (RA) carries risk for infectious complications. Understanding the risks of different therapeutic options is essential for making treatment decisions and appropriately monitoring patients. This review examines data on the risks for serious infections and other key infections of interest for the major classes of agents in use for RA: glucocorticoids, conventional synthetic disease-modifying antirheumatic drugs (DMARDs), biologics and Janus kinase (JAK) inhibitors. Conventional synthetic DMARDs have an excellent safety profile with recent data available supporting the relative safety of methotrexate. Tumour necrosis factor (TNF) inhibitors are associated with an increase in the risk of serious infections. Risk with other biological agents and with JAK inhibitors varies somewhat but overall appears similar to that of TNF inhibitors, with JAK inhibitors also associated with a greater risk of herpes zoster. Glucocorticoids have a dose-dependent effect on serious infection risk—at higher doses risk of infection with glucocorticoids is substantially greater than with other immunomodulatory therapies, and even low-dose therapy carries a risk of infection that appears to be similar to that of biological therapies.

Objectives:To study infectious complications of therapy with biologics, analyze the frequency of withdrawal of bDMARDs due to infectious complications.Methods:The ambispective analysis included data on 505 cases of prescribing biologics with different mechanism of action in 188 patients with rheumatoid arthritis (160 women, 28 men).Results:Patients in the study group received from 2 to 5 bDMARDs, mediana (25% -75%) 2 (2-3). Biologics were discontinued 326 times, of which due to the development of serious adverse reactions - 70 times, of which due to the development of infectious complications - 16 times (5% of all cases of discontinuations, 29% of all serious adverse reactions). During treatment with the first bDMARD, infectious complications that required discontinuation of the drug developed in 5.3% of cases (N = 10), with the second bDMARD - in 5.2% of cases (N = 4), no statistical differences were found between these groups. On the background of treatment with the third bDMARD, infectious complications led to the withdrawal of treatment in 14.3% of cases (N = 1), in the fourth - 0%, and in the fifth - 33.4% of cases (N = 1). There was no correlation between the number of sequentially prescribed biologics and the incidence of infectious complications. Most often, serious infections developed during treatment with drugs of the TNF-α inhibitor group (infliximab, etanercept, adalimumab, golimumab, certolizumab pegol) and tofacitinib. Out of 16 cases of infectious complications, 5 were associated with tuberculosis infection.Conclusion:Infectious complications make up a significant proportion (29%) of all serious adverse reactions leading to the discontinuations of biologics in patients with rheumatoid arthritis. The frequency of discontinuation of bDMARDs due to infectious complications was about 5% and did not change during treatment with both the first and second biologics. It is necessary to remain alert about tuberculosis infection and examine patients before prescribing and during treatment with bDMARDs.Disclosure of Interests:None declared

ABSTRACT Eight female and eight male rats were castrated at the age of 8 to 10 weeks. Four spayed and four orchidectomized rats received one oestrone/cholesterol pellet (200 μg oestrone) on the day of operation (day 0), a second pellet on day 11 and a third on day 23. The remaining animals received four oestrone/cholesterol pellets at these times. The fluctuations in the prolactin levels in the circulation induced by the oestrogen challenges in these animals were followed during 31 days by radioimmunoassays performed on days 3, 7, 9, 14, 15, 17, 23, 24, 25, 28 and 31. The results suggested that the homoeostatic mechanism regulating plasma levels of prolactin was capable of withstanding the three time-spaced oestrogen challenges only in the spayed animals receiving the lower doses of oestrogen, since it allowed the mean values of the prolactin levels to remain fairly constant during the first 4 weeks. The levels in this group rose to much higher levels only on day 31. The higher doses of oestrone in the spayed rats and both dose levels of oestrone in the orchidectomized animals apparently resulted in a primary break-down of the homoeostatic mechanism, since the prolactin levels in the animals of these groups rose to much higher levels either on day 7 or on day 9. This was followed by a period during which the prolactin levels appeared to be more or less under control, until a second and probably definitive failure of the homoeostatic mechanism allowed the mean levels to rise sharply again.

ABSTRACT The authors have endeavoured to clarify the frequency of the hyperoestrogenismus syndrome in women with rheumatoid arthritis, aged 17–38 years, by means of clinical and cytologic studies, and by hormonal analyses. The material comprises 32 patients. Of these, 30 were suitable for cytologic observation. In 5 (17 %) of these 30 patients, the hyperoestrogenismus syndrome (17 %) may be considered definitely established. Aggravation of the joint symptoms in the pre-menstrual phase was reported by 41 % of the patients. Values for excretion of oestrogen exceeding 200 mouse units/24 hours were noted one week before menstrual bleeding in 8 of 19 women; the mean for oestrogen excretion was 268 mouse units/24 hours. Gonadotrophins were studied in the same urine samples, and the mean excretion was 22 mouse units/24 hours (range 7–65 m. u.). The excretion mean for 17-ketosteroids, simultaneously studied, was 9.1 mg/24 hours (range 2.3–18.0 mg). Side-finding in the material were made: incipient cervical cancer in one patient, ovarial tumour in one, and trichomoniasis in seven.

This study was initiated on 24 prepubertal Holstein x Kankrej crossbred heifers of nearly identical age (7-9 months) and body weight (130-140 kg) at University farm to evaluate the effect of high plane of nutrition on blood biochemical and minerals profile and the age at puberty. Twelve heifers were managed under routine farm feeding (control) and the rest 12 under ideal optimum feeding regime (treatment) that included extra 1 kg concentrate, 30 g min mix and ad-lib dry fodder. The body weight and ovarian ultrasonography together with blood sampling was carried out at monthly interval from 10 to 18 months of age to study the ovarian dynamics and blood biochemical changes. High plane of nutrition to growing heifers was beneficial in reducing the age of onset of puberty (by 2-3 months) compared to routine farm fed group. The mean plasma total protein and cholesterol concentrations showed a rising trend with significant variations from 10 to 16 months of age, where it got mostly stabilized indicating adult profile. The activity of enzymes GOT and GPT also rose gradually and significantly from 10 months till 14-15 months of age, and thereafter it remained more or less static till 18 months of age. The levels of both these enzymes were higher, with lower protein and cholesterol, in control than the treatment group from 15-16 months of age onwards. The mean plasma levels of both calcium and phosphorus increased gradually and significantly with advancing age till 16-17 months of age, with little higher values in supplemented than a control group. The plasma levels of zinc, iron, copper, and cobalt also showed rising trend with significant differences between 10th and 12th-14th months of age, and from 15th to 18th months of age the levels were statistically the same in all the groups with slightly higher values in the treatment group.

Background:Enthesitis is the clinical hallmark of spondylarthritis. It refers to the inflammation of joint attach in the bone. Several sites enthesitis may be affected, and a wide variety of scoring systems were available.Objectives:We aimed to determine the prevalence of axial enthesitis in the anterior chest wall (ACW), and its correlation with peripheral sites especially, the Achilles tendon (AT).Methods:We conducted a prospective study including patients with SpA according to the ASAS criteria. Sociodemographic data, as well as disease characteristics, were recorded. The Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) was used to assess clinical entheses (first and seventh costochondral joints, posterior superior iliac spine, anterior superior iliac spine, iliac crest, and Achilles tendon insertion). The presence of enthesitis on the US was then assessed in the right and left sternoclavicular (SCJ), manubriosternal (MSJ) joints, as well as in the AT, using Esaote My Lab 50.Results:The study included 47 patients with SpA: axial (n=26), axial and peripheral (n=21). There was a female predominance (sex ratio: 0.2). The mean age was 42.2 years ± 12.6 [11-70]. The age of onset of the disease was <40 years in 59.6% of cases. Tenderness in entheseal sites was found in 63.8% of patients, especially in the plantar fascia and AT (32.7%, 6%, respectively). The mean MASES score was 2.9 [0-13]. Clinical ACW involvement (29.1%) was at follows: 1st right chondro-sternal joint (CSJ) (19.1%), 1st left CSJ (25.5%), 7th right CSJ (27.7%) and 7th left CSJ (31.9%).US involvement of the ACW was 14.3%. Enthesitis of the AT was found in 70% of cases on US examination. ACW US involvement was correlated neither to the BMI nor to MASES score (p=0.16, p=0.6 respectively). Similarly, there was no correlation between the presence of US ACW enthesitis and clinical nor the US AT enthesitis (p=0.09, p=0.209, respectively).Conclusion:Our study showed that ACW enthesitis is frequent in SpA, especially by US screening. This axial enthesitis, don’t necessarily reflect a simultaneous clinical or US involvement of the peripheral entheses. Further studies are needed to characterize this subtype of SpA.References:[1]Verhoeven F, Guillot X, Godfrin-Valnet M, Prati C, Wendling D.

Foot Disease

Background:Foot disease is a common problem in rheumatoid arthritis (RA). Therapeutic decisions are often based on clinical examination (CE) alone, which can be adversely affected by factors such as deformity, obesity, and peripheral edema. Ultrasonography (US) has previously been shown to be more sensitive than CE for detecting synovitis and tenosynovitis in RA forefeet, but few data exist for the hindfoot and ankle.Objectives:The aim of this study was to compare CE and US for the detection of hindfoot and ankle synovitis and tenosynovitis in patients with established RA.Methods:We conducted a cross-sectional study including patients with RA (ACR/EULAR 2010). Demographic data and disease parameters were collected. CE was performed by a rheumatologist for the presence or absence of tenderness, swelling, and mobility restriction of both ankles. The following tendons were examined for tenosynovitis: tibialis anterior (TA) and posterior (TP), fibularis longus (FL), and brevis (FB) (assessed together). In a second time, US examination of the tibiotalar, talonavicular, and subtalar joints and the same tendons as CE was performed by a blinded radiologist experienced in musculoskeletal imaging using a Philips HD11 device with a high-frequency linear transducer. The presence or absence of synovitis and tenosynovitis was recorded, and the composite synovitis score (power doppler / grayscale ultrasound (PDUS)) was measured for each joint. The US score of each patient was defined by the sum of the composite scores of the joints studied (0-30). A p-value <0.05 was considered significant.Results:Sixty-two feet were examined in 31 RA patients (25 women and six men) with a mean age of 54.8±10.8 years old [32-70]. The mean disease duration was 8.5±7.2 years [1-37]. Rheumatoid Factor (RF) and Anti-Citrullinated Peptides Antibodies (ACPA) were positive in 61.3% and 83.8% of cases. The mean DAS28 ESR was 3.8±1.5 [0.6-7].Clinical examination of ankles revealed tenderness in 57.4% of cases, swelling in 38.8% of cases, and restriction in the range of motion in 11.1% of cases. TA tenosynovitis was noted in 14.8% of cases, TP tenosynovitis in 22.2% of cases, and FL and FB tenosynovitis in 31.5% of cases.US showed tibiotalar synovitis in 59.3% of cases, talonavicular synovitis in 64.8% of cases, and subtalar synovitis in 46.3% of cases. TA tenosynovitis was noted in 5.6% of cases, TP tenosynovitis in 22.2% of cases, and FB and FL tenosynovitis in 25% and 11.1% of cases respectively.An association was found between clinical tenderness and US synovitis of the tibiotalar joint (p=0.013) and the talonavicular joint (p=0.027). No association was noted between clinical swelling and US synovitis in these joints.No association was noted between clinical and US tenosynovitis of TA (p=0.279), TP (p=0.436), FB (p=0.495) and FL (p=0.315).Conclusion:Clinical examination of RA ankles may be challenging and needs to be coupled with US, which is more sensitive and accurate in the detection of synovitis and tenosynovitis.Disclosure of Interests:None declared

Background:Musculoeskeletal ultrasound (MSUS) is frequently used in several rheumatology units to detect subclinical inflammation in patients with joint symptoms suspected for progression to inflammatory arthritis (IA). Synovitis grade I (EULAR-OMERACT combined score) is known to be a casual finding in healthy individuals, but studies headed to unravel its possible role on rheumatic diseases are sparse.Objectives:To investigate the correlation between synovitis grade I, and the diagnosis of IA made after a year follow-up period since MSUS findings, in patients of an MSUS-specialized unit of a Rheumatology Department.Methods:We conducted a descriptive, retrospective and unicentric study. 30 patients were selected from the MSUS-specialized unit of our Rheumatology Department from July-18 to January-19. Patients presenting synovitis grade 0 (exclusively), 2 and/or 3 on combined score were excluded. Data collection at baseline included age, sex, immunological profile and previous physical examination to the MSUS findings, as well as the diagnosis made by the rheumatologist in 1-year visit follow-up: dividing the patient sample into two groups: those who were diagnosed with IA and those not. Non-parametric statistical tests for comparing means were used.Results:The mean age was 51,6 years and 70% were females. 6 (20%) patients were diagnosed with inflammatory arthritis after a year follow-up: 2 (4,8%) psoriatic arthritis, 1 (3,3%) undifferentiated arthritis, 1 (3,3%) rheumatoid arthritis, 1 (3,3%) Sjögren’s syndrome. Non-inflammatory arthropathies were also found 24 (80%), of which, 12 (40%) were non-specific arthralgias and 8 (19%) osteoarthritis.In the group of patients who did not developed an IA the mean C-reactive protein (CPR) value was 3,12 mg/L and erythrocyte sedimentation rate (ESR) was 8,2 mm; all of them were rheumatoid factor (RF) positive and ACPA-negative except one patient. 5 (31,3%) patients presented low antinuclear antibodies (ANAs) levels. In those who HLA B-27 and Cw6 were tested (4,25%); both were negative except for one that was HLA B-27 positive. The median number of swollen and painful joint count was 0, and the mean of joints with MSUS involvement was 3,5; the mean involved metacarpophalangeal (MCP) joints was 1,83; proximal interphalangeal (PIP) joints was 1,48 and distal interphalangeal (DIP) joints 0,21.Among the group of patients that developed an IA the mean of CPR and ESR was 9,27 mg/L and 14,17 mm respectively; 2 (33%) patients were RF- positive, and 1 ACPA-positive. ANAs were positive in 3 cases (50%). The median of swollen joint count was 2 and for painful joint count was 0, the median of joints with MSUS involvement was 4,5. The mean of MSUS involvement was for MCP, PIP and DIP joints: 1,67, 2 and 0. Comparing the means of CPR values in the two groups with Student’s t-test we obtained a statistically significant difference (p=0,023). No other significant differences were found.Conclusion:Despite the limitations and possible statistical bias, the presence of MSUS-defined synovitis grade I and elevated CRP levels could be related to further diagnoses of inflammatory arthropathy. Besides, the absence of synovitis in DIP joints might have a diagnostic role. Normal physical exploration and normal levels of CRP might suggest low MSUS value. However, further research is needed to clarify the role of MSUS-defined synovitis grade I.References:[1]D’Agostino MA et al.
