    Gouty arthritis is one of the most common rheumatic diseases. The clinical burden of gouty arthritis has historically been well recognized; however, gout is often misdiagnosed and mismanaged. The prevalence of gout is rising and is likely attributed to several factors including increased incidence of comorbidities, lifestyle factors, and increased use of causative medications. With the increasing prevalence, there have been several innovations and evidence-based updates related to the diagnosis and management of gout. Acute gouty arthritis should be treated with nonsteroidal antiinflammatory drugs (NSAIDs), colchicine, or corticosteroids, or a combination of two agents. Xanthine oxidase inhibitor therapy remains the consensus first-line treatment option for the prevention of recurrent gout. Add-on therapies that reduce serum urate concentration include traditional uricosuric agents and a novel uric acid reabsorption inhibitor. Prophylaxis of acute gout with NSAIDs, colchicine, or corticosteroids is universally recommended when initiating any urate-lowering therapy in order to prevent acute gouty arthritis for a period of at least 6 months. In this review, we discuss the epidemiology and risk factors for gouty arthritis and evaluate diagnostic strategies and therapeutic regimens for the management of gout, including a new drug approval.

    Indium-111-labeled leukocyte scintigraphy was performed on a 66-yr-old male with polyarticular acute gouty arthritis. Images revealed intense labeled leukocyte accumulation in a pattern indistinguishable from septic arthritis, in both knees and ankles, and the metatarsophalangeal joint of both great toes, all of which were involved in the acute gouty attack. Joint aspirate as well as blood cultures were reported as no growth; the patient was treated with intravenous colchicine and ACTH for 10 days with dramatic improvement noted. Labeled leukocyte imaging, repeated 12 days after the initial study, revealed near total resolution of joint abnormalities, concordant with the patient's clinical improvement. This case demonstrates that while acute gouty arthritis is a potential pitfall in labeled leukocyte imaging, in the presence of known gout, it may provide a simple, objective, noninvasive method of evaluating patient response to therapy.

    Chronic kidney disease (CKD) is a comorbid condition that affects, based on recent estimates, between 47% and 54% of patients with gouty arthritis. However, data from randomized controlled trials in patients with gouty arthritis and CKD are limited, and current gouty arthritis treatment guidelines do not address the challenges associated with managing this patient population. Nonsteroidal anti-inflammatory drugs and colchicine are recommended first-line treatments for acute gouty arthritis attacks. However, in patients with CKD, nonsteroidal anti-inflammatory drugs are not recommended because their use can exacerbate or cause acute kidney injury. Also, colchicine toxicity is increased in patients with CKD, and dosage reduction is required based on level of kidney function. Allopurinol, febuxostat, and pegloticase are all effective treatments for controlling elevated uric acid levels after the treatment of an acute attack. However, in patients with CKD, required allopurinol dosage reductions may limit efficacy; pegloticase requires further investigation in this population, and febuxostat has not been studied in patients with creatinine clearance<30 mL/min. This article reviews the risks and benefits associated with currently available pharmacologic agents for the management of acute and chronic gouty arthritis including urate-lowering therapy in patients with CKD. Challenges specific to primary care providers are addressed, including guidance to help them decide when to collaborate with, or refer patients to, rheumatology and nephrology specialists based on the severity of gout and CKD.

    Background The Chuanhu anti-gout mixture has been used for many years in the treatment of gout in Chinese Traditional Medicine, and current methods for treatments for acute gouty arthritis have been either less effective or have had serious side effects. Methods In this 12-week, double-blind, double-dummy, non-inferiority study, outpatient individuals with newly diagnosed acute gouty arthritis were randomly assigned to receive Chuanhu anti-gout mixture or colchicine. Both the study investigators and the participants were masked to the treatment assignments. The primary outcome was the recurrence rate of acute gouty arthritis, and the secondary outcomes were changes in white blood cells (WHC) and C-reactive protein (CRP). This trial is registered at ISRCTN.org as trial ISRCTN65219941. Results A total of 176 patients were randomly assigned to receive either the Chuanhu anti-gout mixture or Colchicine. The overall recurrence rates in the Chuanhu anti-gout mixture group (CH group) and the Colchicine group (Col group) were 12.50% vs 14.77% (difference -2.22%, 95% confidence interval (95% CI): -10.78%~6.23%), meeting the predefined non-inferiority criterion of 15%, as did the data for WHC and CRP. The incidence of adverse events (mainly diarrhea) was less in the Col group than in the CH group (2.27% vs 28.41%, 95% CI 0.01~0.26). In addition, changes in blood uric acid, alanine aminotransferase, aspartate aminotransferase and creatinine in the CH group were significantly larger compared to those in the Col group (P<0.05). Conclusions The Chuanhu anti-gout mixture was non-inferior to colchicine for the treatment of acute gouty arthritis. The study suggested that the Chuanhu anti-gout mixture can be considered an alternative choice for the treatment of acute gouty arthritis because of its lower incidence of adverse events and its protection of kidney and renal function.

    Gouty arthritis is characterized by inflammation induced by monosodium urate (MSU) crystal deposition, which is resulted by an increase of serum urate concentration. The management of gout, especially the recurrent acute attacks of chronic gouty arthritis, is still a problem to be resolved. In this study, we aimed to develop the preventive and therapeutic effect of resveratrol on gouty arthritis. MSU was used to induce gouty arthritis in the foot pad of C57BL/6 mice. Yeast polysaccharide and potassium oxonate were used to induce hyperuricemia in Kunming mice. Resveratrol was intraperitoneal injected to the mice in the treatment group. The pad inflammation and the level of serum uric acid were investigated to estimate the effect of resveratrol in gouty arthritis. Hyperuricemia was significantly detected in the mice treated with yeast polysaccharide and potassium oxonate, and gouty arthritis was successfully induced with MSU in mice. We further identified that resveratrol inhibited pad swelling and pad 99mTc uptake in gouty mice. Moreover, serum uric acid level was also decreased by resveratrol in hyperuricemia mice. This study highlighted that resveratrol might be applied to prevent the recurrent acute attack of gouty arthritis because of its inhibition of articular inflammation and down-regulation of serum uric acid.

    Objective This study assessed the efficacy and safety of canakinumab, a fully human anti-interleukin 1β monoclonal antibody, for prophylaxis against acute gouty arthritis flares in patients initiating urate-lowering treatment. Methods In this double-blind, double-dummy, dose-ranging study, 432 patients with gouty arthritis initiating allopurinol treatment were randomised 1:1:1:1:1:1:2 to receive: a single dose of canakinumab, 25, 50, 100, 200, or 300 mg subcutaneously; 4×4-weekly doses of canakinumab (50+50+25+25 mg subcutaneously); or daily colchicine 0.5 mg orally for 16 weeks. Patients recorded details of flares in diaries. The study aimed to determine the canakinumab dose having equivalent efficacy to colchicine 0.5 mg at 16 weeks. Results A dose-response for canakinumab was not apparent with any of the four predefined dose-response models. The estimated canakinumab dose with equivalent efficacy to colchicine was below the range of doses tested. At 16 weeks, there was a 62% to 72% reduction in the mean number of flares per patient for canakinumab doses ≥50 mg versus colchicine based on a negative binomial model (rate ratio: 0.28–0.38, p≤0.0083), and the percentage of patients experiencing ≥1 flare was significantly lower for all canakinumab doses (15% to 27%) versus colchicine (44%, p<0.05). There was a 64% to 72% reduction in the risk of experiencing ≥1 flare for canakinumab doses ≥50 mg versus colchicine at 16 weeks (hazard ratio (HR): 0.28–0.36, p≤0.05). The incidence of adverse events was similar across treatment groups. Conclusions Single canakinumab doses ≥50 mg or four 4-weekly doses provided superior prophylaxis against flares compared with daily colchicine 0.5 mg. PMID:21540198

    Background At present there are several kinds of medicine for treating acute gout arthritis (AGA). This study compared the efficacy and safety of prednisolone, etoricoxib, and indomethacin in the treatment of AGA. Material/Methods This was an open-label, randomized, active-comparator study in patients with AGA. Patients were randomized to 4 days of prednisolone 35 mg qd, etoricoxib 120 mg qd, or indomethacin 50 mg tid. The primary efficacy endpoint was the reduction of self-assessed pain in the index joint from baseline. Secondary endpoints included changes in physician’s assessment of tenderness, erythema, swelling, and joint activity; patient assessment of response to therapy; and safety. Results We analyzed 113 patients. Baseline demographics were comparable among treatment groups. Oral prednisolone, etoricoxib, and indomethacin were similarly effective in improving pain, tenderness, and joint activity over 4 days. For inflammation, oral prednisolone, etoricoxib, and indomethacin were similarly effective in reducing erythema, but prednisolone might be more effective in reducing swelling than indomethacin. The patient response to therapy was similar in the 3 groups. There were more total adverse events with indomethacin compared with the other 2 drugs. Conclusions Efficacy was comparable among prednisolone, etoricoxib, and indomethacin for the treatment of AGA. Prednisolone might be more effective in reducing inflammation and it had a better safety profile. PMID:26965791

    Percutaneous radiofrequency thermal ablation (RFA) is considered an effective technique for providing local control in the majority of Hepatocellular carcinoma (HCC) patients. Although RFA is generally well tolerated, recent studies have reported complications associated with RFA. We describe a case of acute gouty arthritis in a 71-year-old man with chronic renal failure who was treated with RFA for a HCC lesion and who had hepatitis B-associated cirrhosis and mild renal insufficiency. Regular surveillance of the patient detected a 3.5 cm HCC lesion. Because the patient had declined surgery, RFA was chosen for therapy. On the third post-procedural day, the laboratory results showed increases in his uric acid and potassium levels, which were compatible with a tumor lysis syndrome. On the 6th post-procedural day, the patient complained of new right knee pain. Subsequent joint aspiration revealed monosodium urate monohydrate crystals. We made the diagnosis of acute gouty arthritis arising from tumor lysis and liver infarction caused by HCC ablation, which was aggravated by acute renal insufficiency. After adequate hydration and administration of oral colchicines, the patient’s right knee pain subsided and the uric acid serum level returned to normal. This is the first described case of acute gouty arthritis after RFA for a HCC lesion in a patient with underlying chronic renal insufficiency. To avoid hyperuricemia and an acute attack of gout after RFA therapy for HCC, early identification of patients at risk is warranted, such as those with a large tumor, rapid tumor growth, and renal insufficiency, and preventative measures should be considered.

    Purpose Patients with gout are similar to those with bacterial infection in terms of the nature of inflammation. Herein we compared the differences in procalcitonin (PCT) levels between these two inflammatory conditions and evaluated the ability of serum PCT to function as a clinical marker for differential diagnosis between acute gouty attack and bacterial infection. Materials and Methods Serum samples were obtained from 67 patients with acute gouty arthritis and 90 age-matched patients with bacterial infection. Serum PCT levels were measured with an enzyme-linked fluorescent assay. Results Serum PCT levels in patients with acute gouty arthritis were significantly lower than those in patients with bacterial infection (0.096±0.105 ng/mL vs. 4.94±13.763 ng/mL, p=0.001). However, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels showed no significant differences between the two groups. To assess the ability of PCT to discriminate between acute gouty arthritis and bacterial infection, the areas under the curves (AUCs) of serum PCT, uric acid, and CRP were 0.857 [95% confidence interval (CI), 0.798–0.917, p<0.001], 0.808 (95% CI, 0.738–0.878, p<0.001), and 0.638 (95% CI, 0.544–0.731, p=0.005), respectively. There were no significant differences in ESR and white blood cell counts between these two conditions. With a cut-off value of 0.095 ng/mL, the sums of sensitivity and specificity of PCT were the highest (81.0% and 80.6%, respectively). Conclusion Serum PCT levels were significantly lower in patients with acute gouty attack than in patients with bacterial infection. Thus, serum PCT can be used as a useful serologic marker to differentiate between acute gouty arthritis and bacterial infections. PMID:27401644

    The anti-inflammatory effect of morin, a dietary bioflavanol was explored on monosodium urate (MSU) crystal-induced inflammation in rats, an experimental model for acute gouty arthritis. Morin treatment (30mg/kg b.wt) significantly attenuated the ankle swelling and the levels of lipid peroxidation, nitric oxide, serum pro-inflammatory cytokines (tumor necrosis factor (TNF) -α, interleukin (IL)-1β, and IL-6), monocyte chemoattractant protein (MCP)-1, vascular endothelial growth factor (VEGF), prostaglandin E2 (PGE2), and articular elastase along with an increased anti-oxidant status (catalase (CAT) and superoxide dismutase (SOD)) in the joint homogenate of MSU crystal-induced rats. Histological assessment revealed that morin limited the diffusion of joint space, synovial hyperplasia, and inflammatory cell infiltrations. The mRNA expression of NLRP3 (nucleotide oligomerization domain (NOD)-like receptor family, pyrin domain containing 3) inflammasome, caspase-1, pro-inflammatory cytokines, MCP-1, inflammatory enzymes (inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2)), and nuclear factor-kappa B (NF-κB) p65 was found downregulated and HPRT (hypo-xanthine phospho-ribosyl transferase) mRNA expression was upregulated in morin treated MSU crystal-induced rats. In addition, morin treatment reduced the protein expression of NF-κB p65, p-NF-κB p65, iNOS, COX-2, and TNF-α. The results clearly demonstrated that morin exert a potent anti-inflammatory effect on MSU crystal-induced inflammation in rats. PMID:27268719

    The objective of this work was to evaluate the sonographic features of gouty arthritis and correlate findings with disease duration. The study was conducted on 100 patients in ambulatory care aged ≥40 y. Inclusion criteria included mono- or oligo-arthritis with effusion of the knee or the first metatarsophalangeal (MTP) joint and no known history of gout. A complete medical history was obtained with emphasis on the known risk factors or causes of gouty arthritis. A 12-MHz Medison linear probe was used for ultrasonography (US). Synovial fluid analysis with polarizing light microscopy was performed on all patients. Ninety-eight knee joints and 33 first MTP joints were examined. Gouty arthritis was found by US in four forms: (i) floating echogenic foci in effusion fluid or Baker cysts, (ii) deposits on the cartilage surface (double contour sign), (iii) erosions and (iv) mature tophus/tophi. These were found in 78.9%, 42.3%, 39.4% and 28.2% of patients, respectively. The overall sensitivity and specificity of US in detecting gout (as defined by the clinical gold standard, i.e., detection of urate crystals by polarizing light microscopy) were 85.9% and 86.7%, respectively. Detection of echogenic foci in effusion fluid was associated with the shortest duration of symptoms (median duration 2 y) followed by double contour sign (3.5 y), erosions (4 y) and tophus (12.5 y). Sonographic findings in gout can be assigned a temporal pattern, with echogenic foci being associated with the shortest and full tophus formation with the longest disease duration. PMID:26995154

    A 69-year-old man was given 8 mg of colchicine intravenously to treat an acute attack of gout. A maintenance dose of 2 mg/day of oral colchicine was then used to prevent recurrence. Three months later, the patient developed thrombocytopenia, followed by leukopenia and then by anemia at three and four months distance, respectively. The patient had shown no signs of acute toxicity with intravenous colchicine, but liver enzymes were raised after two months of oral treatment. The sequential involvement of the three blood precursor lines, in the order to their physiological half-lives, suggests direct toxicity, rather than idiosyncrasy, due to slow accumulation of the drug within target cells. The prophylactic use of colchicine, especially in the elderly, is questioned. PMID:6532622

    Thirty patients with gouty arthritis were studied over 3 years. The diagnosis was established with the help of polarised light microscopy. All the patients were males, with a median age of 45 years. They belonged to the middle or upper socio-economic class and were obese (mean body mass index 29.7). Chronic alcoholism, diabetes mellitus and hypertension were present in one patient each. No patient had symptomatic coronary artery disease. Although 6 patients had a history of renal colic, only one had gouty nephropathy with chronic renal failure. Six patients had a positive family history of gout. The disease involved mostly the joints of the lower extremity and podagra was observed in 70% of patients. Eight patients had tophi at various sites. There were 17 'over producers' and 13 'under excretors' of uric acid. The treatment consisted of patient education, symptomatic control with non steroidal anti-inflammatory drugs and/or colchicine and antihyperuricaemic therapy. The overproducers were treated with allopurinol while the under excretors were treated with [corrected] sulfinpyrazone. In general, there was a good response to therapy as indicated by lowering of serum uric acid and the number of painful episodes per year. The overall profile of the disease appears similar to that seen in the West. PMID:2384454

    Acute septic arthritis may develop as a result of hematogenous seeding, direct introduction, or extension from a contiguous focus of infection. The pathogenesis of acute septic arthritis is multifactorial and depends on the interaction of the host immune response and the adherence factors, toxins, and immunoavoidance strategies of the invading pathogen. Neisseria gonorrhoeae and Staphylococcus aureus are used in discussing the host-pathogen interaction in the pathogenesis of acute septic arthritis. While diagnosis rests on isolation of the bacterial species from synovial fluid samples, patient history, clinical presentation, laboratory findings, and imaging studies are also important. Acute nongonococcal septic arthritis is a medical emergency that can lead to significant morbidity and mortality. Therefore, prompt recognition, rapid and aggressive antimicrobial therapy, and surgical treatment are critical to ensuring a good prognosis. Even with prompt diagnosis and treatment, high mortality and morbidity rates still occur. In contrast, gonococcal arthritis is often successfully treated with antimicrobial therapy alone and demonstrates a very low rate of complications and an excellent prognosis for full return of normal joint function. In the case of prosthetic joint infections, the hardware must be eventually removed by a two-stage revision in order to cure the infection. PMID:12364368

    RuPeng15 Powder (RPP15) is a herbal multicompound remedy that originates from traditional Tibetan medicine and possesses antigout, anti-inflammatory, and antihyperuricemic properties based on the traditional conceptions. The present study was undertaken to evaluate the therapeutic effect of PRP15 in rat gouty arthritis induced by monosodium urate (MSU) crystals. In the present study, we found that treatment with RPP15 (0.4, 0.8, and 1.2 g/kg) in rats with gouty arthritis induced by MSU crystals significantly attenuated the knee swelling. Histomorphometric and immunohistochemistry analyses revealed that MSU-induced inflammatory cell infiltration and the elevated expressions of nuclear transcription factor-κB p65 (NF-κB p65) in synovial tissues were significantly inhibited, and enzyme-linked immunosorbent assay (ELISA) result showed that MSU-induced high levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-8 (IL-8) in synovial fluid were reduced by treatment with RPP15 (0.4, 0.8, and 1.2 g/kg). We conclude that RPP15 may be a promising candidate for the development of a new treatment for gout and its activity of antigout may be partially related to inhibiting TNF-α, IL-1β, IL-8, and NF-κB p65 expression in the synovial tissues.

    Based on traditional Chinese medicinal theories on gouty arthritis, Zisheng Shenqi decoction (ZSD), a novel Chinese medicinal formula, was developed due to its multiple functions, including reinforcing renal function, promoting blood circulation and relieving pain. In the present study, the effect of ZSD on monosodium urate (MSU) crystal-induced gouty arthritis in rats was investigated and the underlying mechanisms were examined. The data from these investigations showed that the injection of MSU crystals into the ankle joint cavity caused significant elevations in ankle swelling and inflammatory cell infiltration into the synovium, whereas these abnormal changes were markedly suppressed by oral administration of ZSD (40 mg/kg) for 7 days. Mechanically, ZSD treatment prevented MSU crystal-induced inflammatory responses, as evidenced by downregulation in the expression levels of NACHT domain, leucine-rich repeat and pyrin domain containing protein (NALP) 1 and NALP6 inflammasomes, decreased serum levels of tumor necrosis factor-α and interleukin-1β, and inhibited activation of nuclear factor-κB. In addition, ZSD administration markedly enhanced the anti-oxidant status in MSU crystal-induced rats by the increase in the activities of superoxide dismutase and glutathione peroxidase, and the levels of reduced glutathione. These results indicated that ZSD effectively prevented MSU crystal-induced gouty arthritis via modulating multiple anti-oxidative and anti-inflammatory pathways, suggesting a promising herbal formula for the prevention and treatment of gouty arthritis.

    Gouty arthritis is a rheumatic disease that is characterized by the deposition of monosodium urate (MSU) in synovial joints cause by the increased serum hyperuricemia. This study used a three-dimensional (3D) flowing microfluidic chip to screen the effective candidate against MSU-stimulated human umbilical vein endothelial cell (HUVEC) damage, and found kinsenoside (Kin) to be the leading active component of Anoectochilus roxburghi, one of the Chinese medicinal plant widely used in the treatment of gouty arthritis clinically. Cell viability and apoptosis of HUVECs were evaluated, indicating that direct Kin stimulation and conditioned medium (CM) from Kin-treated macrophages both negatively modulated with MSU crystals. Additionally, Kin was capable of attenuating MSU-induced activation of nuclear factor-κB/mitogen-activated protein kinase (NF-κB/MAPK) signaling, targeting IκB kinase-α (IKKα) and IKKβ kinases of macrophages and influencing the expressions of NF-κB downstream cytokines and subsequent HUVEC bioactivity. Inflammasome NLR pyrin domain-containing 3 (NALP3) and toll-like receptor 2 (TLR2) were also inhibited after Kin treatment. Also, Kin downregulated CD14-mediated MSU crystals uptake in macrophages. In vivo study with MSU-injected ankle joints further revealed the significant suppression of inflammatory infiltration and endothelia impairment coupled with alleviation of ankle swelling and nociceptive response via Kin treatments. Taken together, these data implicated that Kin was the most effective candidate from Anoectochilus roxburghi to treat gouty arthritis clinically. PMID:27584788

    Symptomatic gout in an artificial joint is exceptionally rare. We present a 68-year-old male patient who developed progressive knee pain and swelling one year after the cemented total arthroplasty of his left knee. The diagnosis was confirmed by crystal identification in the synovial fluid. Beside thorough workout to rule out infection in a painful and inflamed prosthetic knee, specific history of gout should be sought and fluid aspirate examined cytologically and under polarised light for crystal arthropathy.

    The present study was undertaken to evaluate the therapeutic effects of Huzhang-Guizhi herb pair (HG), firstly included in Hu-Zhang Power documented in Taiping Shenghui Fang, on monosodium urate (MSU) crystals-induced gouty arthritis in rats. We found that pretreatment with HG in rats with gouty arthritis could significantly attenuate the ankle joint swelling, and this beneficial antigout effect might be mediated, at least in part, by inhibiting tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) production in synovial fluid as well as nuclear transcription factor-κB p65 (NF-κB p65) protein expression in synovial tissue. Moreover, metabonomic analysis demonstrated that 5 and 6 potential biomarkers associated with gouty arthritis in plasma and urine, respectively, which were mainly involved in energy metabolism, amino acid metabolism, and gut microbe metabolism, were identified. HG could reverse the pathological process of MSU-induced gouty arthritis through regulating the disturbed metabolic pathways. These results provided important mechanistic insights into the protective effects of HG against MSU-induced gouty arthritis in rats. PMID:26989428

    Gouty knee arthritis refers to a form of inflammatory diseases caused by deposits of needle-like crystals of uric acid in knee joint. The aim of this study was to assess the efficacy and safety of arthroscopic debridement in combination with oral medication versus oral medication alone for the treatment of gouty knee arthritis. A total of 60 patients with gouty knee arthritis were randomized to receive either arthroscopic surgery in combination with oral medication or oral medication alone. Efficacy was assessed with the angle of motion, functions, and visual analog scale (VAS). These indices were measured prior to treatment and at 2, 4, 12, 24, and 48 weeks posttreatment. Surgery- and medication-related complications were observed. Significant differences in flexion and extension of the knee joint, lymphoma scores, and VAS were detected between the two groups at 2, 4, and 12 weeks posttreatment (P < 0.05) but not at weeks 24 and 48 posttreatment (P > 0.05) . Significant differences in these indices were detected at different time points in each group (P < 0.05), except between weeks 24 and 48 (P > 0.05). Arthroscopic surgery in combination with oral medication is superior to single oral medication in the flexion and extension of the knee joint, lymphoma scores, and pain relief (VAS) before 24 weeks, although no statistical differences were detected in the efficacy after 24 weeks, and in medication-related safety between the two groups. Although arthroscopic debridement cannot replace systemic uric acid-lowering treatments such as medication and dietary control, it is still an effective approach. PMID:26730077

    Sanmiao formula (SM) is a compound prescription, which has been used in traditional Chinese medicine since the Ming Dynasty for gouty and rheumatoid arthritis treatments. However, no evidence has been unfolded to show the relationship between SM and gouty arthritis (GA), particularly inhibiting cartilage matrix degradation. In the present study, we undertook a characterization of anti-GA activity of SM using an in vivo rat model induced by potassium oxonate and cold bath together with in vitro studies with chondrocytes for further molecular characterization. Potassium oxonate and cold bath rats were treated with SM at doses of 7.2g/kg per day for 5days. SM treatments significantly suppressed the swelling rate and the severe pathologic changes in the joints of the animals in gout model. Inflammatory factors count by ELISA analysis, SM exhibited inhibition on IL-1β and TNF-α. Moreover, histological analysis of the joints and SM-serum substantially interfered with the MSU-induced expression of glycosaminoglycans (GAG), up-regulated the content of proteoglycan. Importantly, SM interfered with GA-augmented expression of matrix metalloproteinases (MMPs) -3 and aggrecanases (ADAMTS)-4, which are considered to be key enzymes in cartilage matrix degradation, and simultaneously augmented GA-reduced tissue inhibitors of metalloproteinases (TIMPs) -1 and -3 expression in the joints and chondrocytes. Therefore, SM is looking forward to be a potential novel agent that could prevent cartilage matrix degradation effectively in gouty arthritis, and this provides a new target for development of new medicines.

    Background: Recent studies suggest that blockade of the NLRP3 (cryopyrin) inflammasome interleukin 1β (IL1β) pathway may offer a new treatment strategy for gout. Objective: To explore the potential utility of rilonacept (IL1 Trap) in patients with chronic active gouty arthritis in a proof-of-concept study. Methods: This 14-week, multicentre, non-randomised, single-blind, monosequence crossover study of 10 patients with chronic active gouty arthritis included a placebo run-in (2 weeks), active rilonacept treatment (6 weeks) and a 6-week post-treatment follow-up. Results: Rilonacept was generally well tolerated. No deaths and no serious adverse events occurred during the study. One patient withdrew owing to an injection-site reaction. Patients’ self-reported median pain visual analogue scale scores significantly decreased from week 2 (after the placebo run-in) to week 4 (2 weeks of rilonacept) (5.0 to 2.8; p<0.049), with sustained improvement at week 8 (1.3; p<0.049); 5 of 10 patients reported at least a 75% improvement. Median symptom-adjusted and severity-adjusted joint scores were significantly decreased. High-sensitivity C-reactive protein levels fell significantly. Conclusions: This proof-of-concept study demonstrated that rilonacept is generally well tolerated and may offer therapeutic benefit in reducing pain in patients with chronic refractory gouty arthritis, supporting the need for larger, randomised, controlled studies of IL1 antagonism such as with rilonacept for this clinical indication.

    Objective: Dioscorea nipponica Makino is one of the most common used traditional Chinese drugs which are used to treat gouty arthritis (GA). Nuclear factor-κB (NF-κB) pathway plays an important role during this process. In the present study, we investigated the effects of total saponins from D. nipponica Makino (TDN) on NF-κB pathway in interleukin-1β (IL-1β) induced fibroblast-like synoviocytes (FLS). Materials and Methods: FLS were divided into three groups: Normal group, model group, which was given 10 μg/L IL-1β to induce the proliferation, and TDN group (10 μg/L IL-1β +100 μg/L TDN). 1 h, 24 h, 48 h, and 72 h after treating, immune fluorescence method was used to detect the cell location of NF-κB p65. Electrophoretic mobility shift assay was used to detect the activation of NF-κB p65. Western blot method was used to detect the protein expressions of NF-κB p65, IκBα, and p-IκBα. Results: TDN could inhibit the activation and transfer of NF-κB p65. As time went on, the expression of NF-κB p65 in the cytoplasm was decreased while it was increased in the nucleus. The expression of p-IκBα was increased, whereas the expression of IκBα was not changed. TDN could regulate these abnormal expressions. Conclusion: TDN may treat GA by regulating NF-κB signal pathway. SUMMARY TDN could inhibit the transfer of NF-κB p65.TDN could inhibit the activation of NF-κB p65.TDN could inhibit the expression of p-IκBa.

    Hypoxanthine-guanine phosphoribosyltransferase (HGPRT) (EC 2.4.2.8) reversibly catalyzes the transfer of the 5-phophoribosyl group from 5-phosphoribosyl-alpha-1-pyrophosphate (PRPP) to hypoxanthine or guanine to form inosine monophosphate (IMP) or guanosine monophosphate (GMP) in the purine salvage pathway. To investigate the catalytic mechanism of this enzyme in the intracellular pathogen Legionella pneumophila, we determined the crystal structures of the L. pneumophila HGPRT (LpHGPRT) both in its apo-form and in complex with GMP. The structures reveal that LpHGPRT comprises a core domain and a hood domain which are packed together to create a cavity for GMP-binding and the enzymatic catalysis. The binding of GMP induces conformational changes of the stable loop II. This new binding site is closely related to the Gout arthritis-linked human HGPRT mutation site (Ser103Arg). Finally, these structures of LpHGPRT provide insights into the catalytic mechanism of HGPRT. PMID:26968365

    Background/Aims: Gout is a common inf lammatory arthritis triggered by the crystallization of uric acid in the joints. Serum uric acid levels are highly heritable, suggesting a strong genetic component. Independent studies to confirm the genetic associations with gout in various ethnic populations are warranted. We investigated the association of polymorphisms in the ABCG2 and SLC2A9 genes with gout in Korean patients and healthy individuals. Methods: We consecutively enrolled 109 patients with gout and 102 healthy controls. The diagnosis of gout was based on the preliminary criteria of the America College of Rheumatology. Genomic DNA was extracted from whole blood samples. We identified single nucleotide polymorphism (SNP) changes in the ABCG2 and SLC2A9 genes using a direct sequencing technique. rs2231142 in ABCG2 and rs6449213 and rs16890979 in SLC2A9 and nearby regions were amplified by polymerase chain reaction. Results: Patients with gout had significantly higher A/A genotype (29.3% vs. 4.9%, respectively) and A allele (52.8% vs. 26.5%, respectively) frequencies of rs2231142 in ABCG2 than did controls (χ2 = 29.42, p < 0.001; odds ratio, 3.32; 95% confidence interval, 2.11 to 5.20). We found novel polymorphisms (c.881A>G and c.1002+78G>A) in the SLC2A9 gene. The univariate logistic regression analysis revealed that the c.881A>G and c.1002+78G>A SNPs were significantly higher in patients than in controls. Conclusions: We demonstrated a significant association between rs2231142 in the ABCG2 gene and gout and identified novel SNPs, c.881A>G and c.1002+78G>A, in the SLC2A9 gene that may be associated with gout in a Korean population.

    2016-01-01

    Gout, an extremely painful arthritis with relapsing inflammatory attacks, is a common inflammatory joint disease in adults. We examined the therapeutic effect of ketotifen, a mast cell stabilizer, on monosodium urate (MSU) crystal-induced acute inflammation. Eight-week-old male Wistar rats were injected with MSU crystals (5 mg per rat) into air pouch. Ketotifen (0, 0.1, 03, and 1 mg/kg) was given 1 hour before MSU crystal injection. Lavage histamine, leukocyte counts, mast cell counts, nitric oxide, and proinflammatory mediator levels were assessed 12 hours after MSU injection. Ketotifen significantly inhibited MSU-induced mast cell activation and histamine concentration in air pouch lavage. Ketotifen dose-dependently inhibited MSU-initiated leukocyte infiltration into the air pouch. Furthermore, ketotifen significantly decreased proinflammatory mediators, including nitric oxide, interleukin-1β, and interleukin-6, production in MSU-treated rats. Ketotifen may attenuate MSU-induced acute inflammation by inhibiting mast cell activation and leukocyte infiltration in rats. Furthermore, ketotifen has the potential to be a new approach in managing patients with gouty inflammation in the future. PMID:23884077

    2014-01-01

    Psoriatic arthritis is a seronegative arthropathy occurring in the presence of psoriasis. In majority of cases, typical psoriatic skin lesions precede joint disease, making diagnosis of psoriatic arthritis without typical skin lesions, a diagnostic challenge. Nail lesions are commonly seen in patients affected by this condition, making it a useful clue in the diagnosis of psoriatic arthritis. This is a case of a 58-year-old Filipino woman presenting with sudden acute urinary retention and weakness of both lower extremities accompanied with active polyarthritis. Onycholytic nail changes initially thought to be a fungal nail infection led to the diagnosis of psoriatic arthritis involving the spine. The patient was eventually treated with methotrexate and non-steroidal anti-inflammatory drugs leading to full resolution of symptoms. The patient is currently ambulatory and on regular follow-up. This case report highlights the importance of clinical and physical findings particularly the nails that would lead to a diagnosis of psoriatic arthritis. PMID:24789155

The joint fluid was inflammatory, with no crystals, and laboratory tests showed marked inflammation leading to antibiotic treatment for suspected septic arthritis. The persistent symptoms and negative results of joint fluid and blood cultures led to discontinuation of the antibiotic therapy after 10 days. Anti-inflammatory with rehabilitation therapy of the knee relieved the symptoms, and the patient was discharged home 3 weeks after her admission. Aseptic arthritis induced by repeated Hyaluronic acid injection is the most likely diagnosis. Physicians should be conscious of this extremely severe complication. PMID:22937184

    Background. There are few data on anakinra use after failure of conventional medications for crystal-induced peripheral arthritis and/or crowned dens syndrome among complex hospitalized patients. Methods. We retrospectively analyzed the outcome of six patients affected with subacute crystal-induced arthritis who had received anakinra in second or third line therapy, including three patients with crowned dens syndrome and three others with gouty arthritis. Patients' comorbidities, reasons for anakinra use and associated drugs, and outcomes were recorded. Results. All patients presented with elevated inflammatory syndrome, systemic symptoms with poly/oligoarthritis. Except for absolute contraindications, all patients were previously treated with full or decreased dose of NSAID, colchicine, and/or glucocorticoids, with unsatisfactory response. All three gouty patients exhibited complete responses in all acute involvements under anakinra within 3 to 5 days, including one of them who needed the reintroduction of colchicine treatment that was previously unsuccessful. Crowned dens syndrome patients, including two with pseudogout and one with subacute hydroxyapatite deposition disease, needed 9 to 11 days to achieve complete response. Tolerance to anakinra was good. Conclusion. In case series of complex hospitalized patients, anakinra showed good activity in crowned dens syndrome and associated crystal-induced peripheral arthritis, with longer treatment duration than in gouty arthritis.

    Tumor necrosis factor-α (TNF-α) is the major target of the therapeutic approach in rheumatoid arthritis. A key issue in the approach to chronic arthritis is the understanding of the crucial molecules driving the transition from the acute phase to the chronic irreversible phase of the disease. In this review we analyzed five experimental arthritis animal models (antigen-induced arthritis, adjuvant-induced arthritis, streptococcal cell wall arthritis, collagen-induced arthritis and SKG) considered as possible scenarios to facilitate interpretation of the biology of human rheumatoid arthritis. The SKG model is strictly dependent on interleukin (IL)-6. In the other models, IL-1β and IL-6, more than TNF-α, appear to be relevant in driving the transition, which suggests that these should be the targets of an early intervention to stop the course toward the chronic form of the disease.

    Acute osteomyelitis and septic arthritis are two infections whose frequencies are increasing in pediatric patients. Acute osteomyelitis and septic arthritis need to be carefully assessed, diagnosed, and treated to avoid devastating sequelae. Traditionally, the treatment of acute osteoarticular infection in pediatrics was based on prolonged intravenous anti-infective therapy. However, results from clinical trials have suggested that in uncomplicated cases, a short course of a few days of parenteral antibiotics followed by oral therapy is safe and effective. The aim of this review is to provide clinicians an update on recent controversies and advances regarding the management of acute osteomyelitis and septic arthritis in children. In recent years, the emergence of bacterial species resistant to commonly used antibiotics that are particularly aggressive highlights the necessity for further research to optimize treatment approaches and to develop new molecules able to fight the war against acute osteoarticular infection in pediatric patients.

    Metabolic alterations are associated with arthritis apart from obesity. However, it is still unclear which is the underlying process behind these metabolic changes. Here, we investigate the role of tumor necrosis factor (TNF) in this process in an acute model of antigen-induced arthritis (AIA). Immunized male BALB/c mice received an intra-articular injection of PBS (control) or methylated bovine serum albumin (mBSA) into their knees, and were also pre-treated with different drugs: Etanercept, an anti-TNF drug, DF2156A, a CXCR1/2 receptor antagonist, or a monoclonal antibody RB6-8C5 to deplete neutrophils. Local challenge with mBSA evoked an acute neutrophil influx into the knee joint, and enhanced the joint nociception, along with a transient systemic metabolic alteration (higher levels of glucose and lipids, and altered adipocytokines). Pre-treatment with the conventional biological Etanercept, an inhibitor of TNF action, ameliorated the nociception and the acute joint inflammation dominated by neutrophils, and markedly improved many of the altered systemic metabolites (glucose and lipids), adipocytokines and PTX3. However, the lessening of metabolic changes was not due to diminished accumulation of neutrophils in the joint by Etanercept. Reduction of neutrophil recruitment by pre-treating AIA mice with DF2156A, or even the depletion of these cells by using RB6-8C5 reduced all of the inflammatory parameters and hypernociception developed after AIA challenge, but could not prevent the metabolic changes. Therefore, the induction of joint inflammation provoked acute metabolic alterations which were involved with TNF. We suggest that the role of TNF in arthritis-associated metabolic changes is not due to local neutrophils, which are the major cells present in this model, but rather due to cytokines. PMID:26742100

    Metabolic alterations are associated with arthritis apart from obesity. However, it is still unclear which is the underlying process behind these metabolic changes. Here, we investigate the role of tumor necrosis factor (TNF) in this process in an acute model of antigen-induced arthritis (AIA). Immunized male BALB/c mice received an intra-articular injection of PBS (control) or methylated bovine serum albumin (mBSA) into their knees, and were also pre-treated with different drugs: Etanercept, an anti-TNF drug, DF2156A, a CXCR1/2 receptor antagonist, or a monoclonal antibody RB6-8C5 to deplete neutrophils. Local challenge with mBSA evoked an acute neutrophil influx into the knee joint, and enhanced the joint nociception, along with a transient systemic metabolic alteration (higher levels of glucose and lipids, and altered adipocytokines). Pre-treatment with the conventional biological Etanercept, an inhibitor of TNF action, ameliorated the nociception and the acute joint inflammation dominated by neutrophils, and markedly improved many of the altered systemic metabolites (glucose and lipids), adipocytokines and PTX3. However, the lessening of metabolic changes was not due to diminished accumulation of neutrophils in the joint by Etanercept. Reduction of neutrophil recruitment by pre-treating AIA mice with DF2156A, or even the depletion of these cells by using RB6-8C5 reduced all of the inflammatory parameters and hypernociception developed after AIA challenge, but could not prevent the metabolic changes. Therefore, the induction of joint inflammation provoked acute metabolic alterations which were involved with TNF. We suggest that the role of TNF in arthritis-associated metabolic changes is not due to local neutrophils, which are the major cells present in this model, but rather due to cytokines. PMID:26742100

    The use of immunobiological agents for the treatment of autoimmune diseases is increasing in medical practice. Anti-TNF therapies have been increasingly used in refractory autoimmune diseases, especially rheumatoid arthritis, with promising results. However, the use of such therapies has been associated with an increased risk of developing other autoimmune diseases. In addition, the use of anti-TNF agents can cause pulmonary complications, such as reactivation of mycobacterial and fungal infections, as well as sarcoidosis and other interstitial lung diseases (ILDs). There is evidence of an association between ILD and the use of anti-TNF agents, etanercept and infliximab in particular. Adalimumab is the newest drug in this class, and some authors have suggested that its use might induce or exacerbate preexisting ILDs. In this study, we report the first case of acute ILD secondary to the use of adalimumab in Brazil, in a patient with rheumatoid arthritis and without a history of ILD. PMID:24626274

    Abstract Currently, there are 5 existing classification criteria for gout: the Rome, New York, American Rheumatism Association (ARA), Mexico, and Netherlands criteria. This study was carried out to determine the performance of these classification criteria in Thai patients presenting with acute arthritis. All consecutive patients presenting with acute arthritis and being consulted at the Rheumatology Unit, Chiang Mai University Hospital from January 2013 to May 2015 were invited to join the study. Gout was defined by the presence of monosodium urate crystals in the synovial fluid or tissue examined by experienced rheumatologists. The 5 existing gout classification criteria were performed and evaluated in all of the patients, who were divided in subgroups of early disease (≤2 years), established disease (>2 years), and those without tophus. There were 136 gout and 97 nongout patients. Sensitivity and specificity across all criteria ranged from 75.7% to 97.1% and 68.0% to 84.5%, respectively. Overall, the Mexico criteria had the highest sensitivity (97.1%), and the ARA survey criteria the highest specificity (84.5%), whereas the Mexico criteria performed well in early disease with sensitivity and specificity of 97.1% and 81.7%, respectively. All 5 criteria showed high sensitivity (from 76.4% to 99.1%) but low specificity (from 30.8% to 65.4%) in established disease. In patients without tophus, the sensitivity and specificity ranged from 64.1% to 95.7% and 68.8% to 85.4%, respectively. The ARA survey criteria across all groups showed consistently high specificity for gout. The 5 existing classification criteria for gout had limited sensitivity and specificity in Thai patients presenting with acute arthritis. The ARA survey criteria are the most suitable for diagnosing gout in Thai people when crystal identification is not available. PMID:26844519

    We present a case report of a four-year-old boy with torcicollis and trismus after acute otitis media. Grisel Syndrome diagnosis in association with temporo-mandibular reactive arthritis was admitted, leading to early conservative treatment. GS should be suspected in a child presenting with torticollis after an upper respiratory tract infection or an ENT surgical procedure. The association with temporo-mandibular reactive findings is somehow rarer but not impossible, due to the close vascular communication between retropharyngeal and pterigoid spaces. PMID:26060148

    PubMed Central

    2011-01-01

    There is a debate whether post-streptococcal reactive arthritis (PSRA) is a separate entity or a condition on the spectrum of acute rheumatic fever (ARF). We believe that PSRA is a distinct entity and in this paper we review the substantial differences between PSRA and ARF. We show how the demographic, clinical, genetic and treatment characteristics of PSRA differ from ARF. We review diagnostic criteria and regression formulas that attempt to classify patients with PSRA as opposed to ARF. The important implication of these findings may relate to the issue of prophylactic antibiotics after PSRA. However, future trials will be necessary to conclusively answer that question.

    Systemic administration of the cytokine, TGF beta 1, profoundly antagonized the development of polyarthritis in susceptible rats. TGF beta 1 administration (1 or 5 micrograms/animal), initiated one day before an arthritogenic dose of streptococcal cell wall (SCW) fragments, virtually eliminated the joint swelling and distortion typically observed during both the acute phase (articular index, AI = 2.5 vs. 11; P less than 0.025) and the chronic phase (AI = 0 vs. 12.5) of the disease. Moreover, TGF beta 1 suppressed the evolution of arthritis even when administration was begun after the acute phase of the disease. Histopathological examination of the joint revealed the systemic TGF beta 1 treatment greatly reduced inflammatory cell infiltration, pannus formation, and joint erosion. Consistent with the inhibition of inflammatory cell recruitment into the synovium, TGF beta 1 reversed the leukocytosis associated with the chronic phase of the arthritis. Control animals subjected to the same TGF beta 1 dosing regimen displayed no discernable immunosuppressive or toxic effects even after 4 wk of treatment. These observations not only provide insight into the immunoregulatory effects of TGF beta, but also implicate this cytokine as a potentially important therapeutic agent. Images PMID:1999490

    Flexor tenosynovitis of the hand is often caused by trauma or infection. Gouty tenosynovitis is an uncommon presentation of the condition and is usually misdiagnosed as infection with the patient undergoing surgery. The coexistence of infection and gout causing flexor tenosynovitis has never been described before in the literature; we report the first ever case and emphasise the importance of its awareness for optimal treatment. A 54-year-old man was initially diagnosed and treated as having infective flexor tenosynovitis and, later, due to a lack of improvement in his symptoms, was discovered to also have gout. We review the literature and suggest management strategy for use in daily clinical practice, including an algorithm, for this presentation. PMID:27358092

    Rofecoxib is a selective cyclo-oxygenase (COX)-2 inhibitor which has little or no effect on the COX-1 isoenzyme at doses up to 1000 mg/day. Rofecoxib has greater selectivity for COX-2 than celecoxib, meloxicam, diclofenac and indomethacin. In well-controlled clinical trials, rofecoxib 12.5 to 500 mg/day has been evaluated for its efficacy in the treatment of osteoarthritis, acute pain and rheumatoid arthritis [lower dosages (5 to 125 mg/day) were generally used in the chronic pain indications]. In the treatment of patients with osteoarthritis, rofecoxib was more effective in providing symptomatic relief than placebo, paracetamol (acetaminophen) and celecoxib and was similar in efficacy to ibuprofen, diclofenac, naproxen and nabumetone. Overall, both the physician's assessment of disease status and the patient's assessment of response to therapy tended to favour rofecoxib. In patients with postsurgical dental pain, pain after spinal fusion or orthopaedic surgery, or primary dysmenorrhoea, rofecoxib provided more rapid and more sustained pain relief and reduced requirements for supplemental morphine use after surgery than placebo. Rofecoxib was more efficacious than celecoxib in patients with acute dental pain and pain after spinal fusion surgery, although celecoxib may have been used at a subtherapeutic dose. In comparison with traditional nonsteroidal anti-inflammatory drugs (NSAIDs) ibuprofen, diclofenac and naproxen sodium, rofecoxib was similar in efficacy in the treatment of acute pain. Although naproxen sodium provided more rapid pain relief than rofecoxib in patients with primary dysmenorrhoea, the reverse was true after orthopaedic surgery: rofecoxib provided more rapid pain relief and less supplemental morphine was needed. Rofecoxib was as effective as naproxen in providing symptomatic relief for over 8700 patients with rheumatoid arthritis. Compared with traditional NSAID therapy, rofecoxib had a significantly lower incidence of endoscopically confirmed

    Acute-onset arthritis is a common clinical problem facing both the general clinician and the rheumatologist. A viral aetiology is though to be responsible for approximately 1% of all cases of acute arthritis with a wide range of causal agents recognised. The epidemiology of acute viral arthritis continues to evolve, with some aetiologies, such as rubella, becoming less common due to vaccination, while some vector-borne viruses have become more widespread. A travel history therefore forms an important part of the assessment of patients presenting with an acute arthritis. Worldwide, parvovirus B19, hepatitis B and C, HIV and the alphaviruses are among the most important causes of virally mediated arthritis. Targeted serological testing may be of value in establishing a diagnosis, and clinicians must also be aware that low-titre autoantibodies, such as rheumatoid factor and antinuclear antibody, can occur in the context of acute viral arthritis. A careful consideration of epidemiological, clinical and serological features is therefore required to guide clinicians in making diagnostic and treatment decisions. While most virally mediated arthritides are self-limiting some warrant the initiation of specific antiviral therapy. PMID:27037381

    Fibrosarcoma is a malignant mesenchymal tumor. To the author’s best knowledge, no previous case of fibrosarcoma arising from gouty tophi has been reported. Here we reported the first case of fibrosarcoma arising from gouty tophi. A case of 58-year-old man was presented with a mass with ulcer and infection in the second joint of left middle finger for 2 months, with long standing gouty tophi. The tumor was biopsied and the biopsy showed complete excision of the tumor. With the pathological and immunohistochemical features considered, the diagnosis of fibrosarcoma associated with gouty tophi was made. The clinical findings, pathological characteristics and treatment were described. PMID:26097616

    Infectious arthritis was induced experimentally in one tarsocrural joint of six horses by intra-articular injection of 1 ml Staphylococcus aureus-saline suspension with the addition of 200 mg methylprednisolone acetate. The corresponding contralateral joint was injected with 1 ml of saline with the addition of 200 mg methylprednisolone acetate, and served as a control. The purpose of the experiment was to examine the effect of corticosteroids on the acute clinical signs of infectious arthritis, and the associated changes in synovial fluid, to separate the effects of a steroid injection from those of infection alone. This should aid early diagnosis of infection. The progression of the infectious arthritis was assessed over nine days by clinical examination and sequential synovial fluid analysis. The corticosteroids masked the clinical signs in some horses for up to the third day although changes in the synovial fluid were present earlier. Cellular changes preceded biochemical changes initially. Leucocyte counts showed a significant increase in cell numbers after infection was established. Persistent neutrophilia, over 90 per cent, together with a pH under 6.9 were the most consistent findings in the infected synovia. Total protein values were lower in infected joints with, than those without, corticosteroids; although there was a progressive rise in total protein concentration throughout the experiment in both groups. Serum and synovial glucose difference and synovial lactate had very little diagnostic value because significant increases due to the corticosteroids were documented in the control joints.

    We found previously that crystals of sodium urate and silicon dioxide (silica) can stimulate the production of endogenous pyrogen (EP), now called interleukin-1 (IL-1), the polypeptide mediator of fever and other aspects of inflammation. We have confirmed and extended the work with urate crystals and have examined 2 other crystals associated with joint problems, hydroxyapatite (HA) and calcium pyrophosphate dihydrate (CPPD). The crystals were added to suspensions of human blood leukocytes (2.5 X 10(6) monocytes/dose, with 10% fresh autologous plasma); after 18 hours of incubation, the EP content of the supernatants was assayed in the rabbit pyrogen test. HA and CPPD crystals neither induced EP production nor reduced the amount of staphylococci-induced EP. Presized (10 - 40 micron) urate crystals were pyrogenic, but less so than the unsized and aggregated urate crystals investigated previously and reexamined here. On ultrasonication, the aggregated urate crystals became first more pyrogenic and then less so as the crystals were dispersed and broken down. Ultrasound did not impart pyrogenicity to HA or CPPD crystals: their failure to stimulate EP/IL-1 production from leukocytes in vitro indicates a difference in their phlogistic properties, compared with crystals of urate or silica. The results with urate crystals have pathogenetic implications in a number of areas of gouty inflammation: initiation of the acute attack, other aspects of the acute-phase response, polyarticular involvement, and the inflammatory consequences of chronic stimulation by tophaceous material.

    Aim. The present investigation was designed to evaluate antiarthritic potential of fractions of hydroalcoholic extract from leaves of P. alba. Materials and Methods. Plumeria alba L. leaves were extracted with hydroalcohol (30 : 70) to obtain hydroalcoholic extract of P. alba. This extract was further fractionated with solvents ethyl acetate and n-butanol to obtain EAPA and BPA, respectively. These fractions were tested against formaldehyde and Freund's complete adjuvant (FCA) induced arthritis. Arthritis assessment, paw volume, body weight, motor incoordination, and nociceptive threshold were measured. On day 21, the animals were sacrificed and histopathology was done. Results. The 100 and 200 mg/kg doses of EAPA and BPA caused a significant (P ≤ 0.05–0.01) reduction in paw swelling in both models. Erythrocyte sedimentation rate (ESR) and spleen weight decreased significantly (P < 0.01) in arthritic rats treated with extracts. There was significant (P < 0.05) improvement in thymus weight in EAPA treated rats whereas significant (P < 0.01) improvement was also seen in haemoglobin level (Hb) in diclofenac treated group. Motor incoordination and nociceptive threshold were also significantly (P ≤ 0.05–0.01) improved. Conclusion. The present study suggests that Plumeria alba L. has protective activity against arthritis and supports the traditional use of P. alba for rheumatism and other inflammatory diseases. PMID:25025056

    Circulating immune complexes were identified in cryoproteins isolated from serial samples of serum from six patients with acute viral hepatitis with and without arthritic symptoms. Cryoprecipitates were analyzed for the presence of hepatitis-B surface antigen (HBsAg) and hepatitis-B surface antibody (anti-HBs) by hemagglutination inhibition and hemagglutination. Complement components were detected by counter electrophoresis, and immunoglobulins were detected by gel diffusion. HBsAg, IgG, and IgM were identified in cryoprecipitates from all hepatitis patients, but were higher in concentration in patients with arthritis. Only cryoprecipitates from hepatitis patients with arthritis contained IgA and complement components C3, C4, and C5 as well as IgG and IgM, which disappear with resolution of the arthritis. The subtypes of IgG in these cryoprecipitates were predominantly the complement-fixing IgG1 and IgG3, HBsAg and anti-HBs were concentrated several-fold in the cryoprecipitates when compared to the serum concentration. Sequential studies in two patients demonstrated that the initial appearance of anti-HBs in the cryoprotein complex was associated with the detection in the complex of IgM suggesting a primary immune response to HBsAg. The C3 activator fragment (C3A) of the properdin complex was found in fresh serum obtained from three hepatitis patients with arthritis and not in uncomplicated hepatitis. The cryoprecipitable immune complexes from patients with arthritis converted C3PA in fresh normal sera to C3A in vitro whereas cryoprotein isolated from patients with uncomplicated hepatitis had no such effect. Thus, the transient appearance of circulating complement-fixing immune complexes in patients with the arthritis of acute hepatitis is associated with activation of both classical and alternate complement pathways and suggests that they play an important role in the pathogenesis of these serum sickness-like extrahepatic symptoms.

    Our objective was to analyse the relationship between circulating cytokines, autoantibodies, acute phase reactants, and disease activity in DMARDs-naïve rheumatoid arthritis (RA) patients (n = 140). All cytokines were significantly higher in the RA cohort than in healthy controls. Moderate-to-strong positive intercorrelations were observed between Th1/Th2/macrophage/fibroblast-derived cytokines. RF correlated significantly with IL-1β, IL-2, IL-4, IL-10, IL-12, G-CSF, GM-CSF, IFN-γ, and TNF (P < .0001), and aCCP and aMCV with IL-1β, IL-2, IL-4, and IL-10 (P < .0002), while IL-6 correlated best with the acute phase reactants, CRP, and SAA (P < .0001). In patients with a DAS28 score of ≥5.1, IFN-γ, IL-1β, IL-1Ra, TNF, GM-CSF, and VEGF were significantly correlated (P < .04–.001) with high disease activity (HDA). Circulating cytokines in RA reflect a multifaceted increase in immune reactivity encompassing Th1 and Th2 cells, monocytes/macrophages, and synovial fibroblasts, underscored by strong correlations between these cytokines, as well as their relationships with RF, aCCP, and aMCV, with some cytokines showing promise as biomarkers of HDA.

    We report a case of an acute pseudogout attack following single-bundle anterior cruciate ligament (ACL) reconstruction in a 35-year-old man. At the initial reconstruction surgery, he was found to have early degenerative changes mainly in the lateral compartment. He presented with acute onset pain and swelling following reconstruction of the ACL. Arthroscopic irrigation was performed and the synovial fluid was positive for calcium pyrophosphate crystals. A pseudogout attack must be considered in the differential diagnosis in cases of acute onset pain and swelling after arthroscopic surgery, especially with the background of degenerative knee changes, and this may signify a poorer long-term outcome.

    Bacteria, viruses, fungi, and parasites can all cause arthritis of either acute or chronic nature, which can be divided into infective/septic, reactive, or inflammatory. Considerable advances have occurred in diagnostic techniques in the recent decades resulting in better treatment outcomes in patients with infective arthritis. Detection of emerging arthritogenic viruses has changed the epidemiology of infection-related arthritis. The role of viruses in the pathogenesis of chronic inflammatory arthritides such as rheumatoid arthritis is increasingly being recognized. We discuss the various causative agents of infective arthritis and emphasize on the approach to each type of arthritis, highlighting the diagnostic tests, along with their statistical accuracy. Various investigations including newer methods such as nucleic acid amplification using polymerase chain reaction are discussed along with the pitfalls in interpreting the tests. PMID:26096095

    The study aimed to investigate the effect of the oral administration for 15 days of either Echinacea (E) or genuphil (a composite of chondroitin sulphate, glucosamine and methyl sulfonyl methane [GCM]) nutraceutical supplements on female rat model of acute or chronic arthritis induced by bacterial outer membrane protein (OMP) from faecal flora of healthy and rheumatic humans. Anti-cyclic citrullinated peptide (anti-CCP2), C-reactive protein (CRP) and rheumatoid factor (RF) values increased (p < 0.05) in both arthritic groups as compared to normal values. The rheumatic markers anti-CCP2, CRP and RF values decreased significantly in E- and GCM-treated groups compared to arthritic none-treated acute or chronic groups. The results of RF values of GCM-treated groups in acute and chronic models decreased exhibiting no statistical difference compared with the normal value. Histological examinations of the hind paw sections revealed moderate inflammation, oedema and mild proliferation of synovial cells in acute arthritic rats and more damage to cartilage and bone with severe inflammation in chronic ones. Echinacea acute treated group showed edema with proliferated synovial membrane and partial damage in cartilage and bone. While in the E-chronic treated group, rough edge with destructed cartilage and bone existed. However, the acute GCM group revealed mild cartilage damage. But the chronic GCM group showed mild synovial cells proliferation and revealed no inflammation with mild cartilage damage edge. Results demonstrated the OMP arthropathic property and through promising light on arthritis treatment using E- or GCM, with the advantage of GMC results over that of E-. The composite GCM is needed for further studies over the dose and duration to assess its preventive effects against the bacterial OMP arthrogenicity. PMID:22173958

    Objective Development of an in vivo imaging method to assess lymphatic draining function in the K/B×N mouse model of inflammatory arthritis. Methods Indocyanine green (ICG), a near-infrared (NIR) fluorescent dye, was injected intradermally into the footpad of wild-type mice, the limb was illuminated with an 806 nm NIR laser, and the movement of ICG from the injection site to the draining popliteal lymph node (PLN) was recorded with a CCD camera. ICG-NIR images were analyzed to obtain 5 measures of lymphatic function across time. K/B×N arthritic mice and control non-arthritic littermates were imaged at one-month of age when acute joint inflammation commenced, and repeated at 3 months when joint inflammation became chronic. Lymphangiogenesis in PLNs was assessed by immunochemistry. Results ICG and its transport within lymphatic vessels were readily visualized and quantitative measures derived. During the acute phase of arthritis, the lymphatic vessels were dilated with increased ICG signal intensity and lymphatic pulses, and PLNs became fluorescent quickly. During the chronic phase, new lymphatic vessels were present near the foot. However, ICG appearance in lymphatic vessels was delayed. The size and area of PLN lymphatic sinuses progressively increased in the K/B×N mice. Conclusion ICG-NIR lymphatic imaging is a valuable method to assess the lymphatic draining function in mice with inflammatory arthritis. ICG-NIR imaging of K/B×N mice identified two distinct lymphatic phenotypes during the acute and chronic phase of inflammation. This technique can be used to assess new therapies for lymphatic disorders. PMID:20309866

    The objective of the study was to identify risk factors for acute exacerbation of interstitial lung disease (ILD) during tocilizumab treatment in patients with rheumatoid arthritis (RA). This is a retrospective, case-control study. We reviewed 395 consecutive RA patients who received tocilizumab. First, we divided the patients according to the presence (RA-ILD) or absence of ILD (non-ILD) assessed by chest X-ray or high-resolution computed tomography, and compared them for characteristics relevant to RA-ILD. Subsequently, focusing on the patients with RA-ILD, we assessed their baseline characteristics and clinical courses comparing patients with acute exacerbation to those without. Comparing 78 with ILD and 317 without ILD, the following were identified as factors related to RA-ILD on multivariate analysis: age 60 years or older (OR 4.5, 95 % CI 2.2-9.4, P < 0.0001), smoking habit (OR 2.9, 95 % CI 1.5-5.5, P = 0.002), and high rheumatoid factor levels (OR 2.8, 95 % CI 1.4-5.5, P = 0.002). Of 78 RA-ILD patients, six developed acute exacerbation during tocilizumab treatment. The median duration between the initiation of tocilizumab treatment and the acute exacerbation occurrence was 48 weeks. While baseline characteristics did not differ between acute exacerbation and non-acute exacerbation groups, patients experiencing acute exacerbation had significantly higher Clinical Disease Activity Index (CDAI) at 24 weeks (20.8 vs. 6.2, P = 0.019). Univariate analysis showed that CDAI > 10 at 24 weeks was a risk factor for acute exacerbation (OR 4.7, 95 % CI 2.1-10.4, P = 0.02).

    Summary Background: The most common cause of low back pain is degenerative disease of the intervertebral disc and other structures of the lumbar spine. However, in some cases other less frequent causes of such pain can be seen, for example septic facet joint arthritis. Until now, only 40 cases of such inflammatory changes within the spine have been reported in the literature. The disease is probably underestimated due to improper diagnostic pathway. Case Report: The authors describe a case of a 53-year-old woman who was repeatedly hospitalized during a five-month period because of an acute, severe low back pain, with sphincter dysfunction, partially resembling sciatic symptoms. Physical examinations revealed also focal tenderness in the area of the lumbar spine. Inflammatory markers (ESR – erythrocyte sedimentation rate, CRP – C-reactive protein) were elevated. Conservative analgetic treatment brought only partial and temporary relief of the pain and symptoms. The final accurate diagnosis of isolated septic facet joint arthritis at the level of L5/S1 was established after several months from the onset of the first symptoms, after performing various imaging examinations, including bone scintigraphy as well as CT and MRI of the lumbosacral spine. The patient fully recovered after antibiotic therapy and surgery, which was proven in several follow-up examinations showing no relevant pathology of the lumbar spine. The authors broadly describe the etiology and clinical symptoms of the septic facet joint arthritis as well as the significant role of imaging methods, especially MRI, in diagnostic process. The authors also discuss currently available treatment options, both conservative and surgical. Conclusions: The diagnostic procedure of septic facet joint arthritis requires several steps to be taken. Establishing a correct diagnosis may be difficult, that is why it is important to remember about rare causes of low back pain and to perform detailed physical

    The aim of this study was to develop and validate a new radiographic damage scoring method (DAmagE index of GoUt; DAEGU) in chronic gout using plain radiography. Two independent observers scored foot x-rays from 15 patients with chronic gout according to the DAEGU method and the modified Sharp/van der Heijde (SvdH) method. The 10 metatarsophalangeal (MTP) and 2 interphalangeal (IP) joints of the first toes of both feet were scored to assess the degrees of erosion and joint space narrowing (JSN). The intraobserver and interobserver reliabilities were analyzed by calculating the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). The correlation between the DAEGU and SvdH methods was analyzed by calculating the Spearman's rho correlation coefficients and Kappa coefficients. The DAEGU method was found to be highly reproducible (0.945-0.987 for the intraobserver and 0.993-0.996 for the interobserver ICC values). The erosion, JSN, and total scores exhibited strong positive correlations between the DAEGU and SvdH methods and also within each method (r = 0.860-0.969, P < 0.001 for all parameters). The DAEGU and SvdH methods were in very good agreement as determined by Kappa coefficient analysis [0.732 (0.387-1.000) for erosion and 1.000 (1.000-1.000) for JSN]. In conclusion, this study revealed that DAEGU method was a reliable and feasible tool in the assessment of radiographic damage in chronic gout. The DAEGU method may provide a more easy assessment of structural damage in chronic gout in the real clinical practice. PMID:26955246

    Objective We aimed to evaluate the safety and efficacy of a fixed-dose combination (FDC) of tramadol and diclofenac versus a standard approved FDC of tramadol and paracetamol, in patients with acute moderate to severe pain. Methods A total of 204 patients with moderate to severe pain due to acute musculoskeletal conditions (n=52), acute flare of osteoarthritis (n=52), acute flare of rheumatoid arthritis (n=50), or postoperative pain (n=50) were enrolled in the study at baseline. Each disease category was then randomized to receive either of two treatments for 5 days: group A received an FDC of immediate-release tramadol hydrochloride (50 mg) and sustained-release diclofenac sodium (75 mg) (one tablet, twice daily), and group B received an FDC of tramadol hydrochloride (37.5 mg) and paracetamol (325 mg) (two tablets every 4–6 hours, up to a maximum of eight tablets daily). The primary efficacy end points were reductions in pain intensity from baseline at day 3 and day 5 as assessed by a Visual Analog Scale (VAS) score. Results Group A showed a significant reduction in the VAS score for overall pain from baseline on day 3 (P=0.001) and day 5 (P<0.0001) as compared with group B. The combination of tramadol-diclofenac resulted in few mild to moderate adverse events (nausea, vomiting, epigastric pain, and gastritis), which required minimal management, without any treatment discontinuation. The number of adverse events in group A was nine (8.82%) compared with 22 (21.78%) in group B, after 5 days of treatment. Conclusion An FDC of tramadol-diclofenac showed a significantly greater reduction in pain intensity and was well tolerated compared with tramadol-paracetamol, resulting in better analgesia in patients suffering from moderate to severe pain due to acute musculoskeletal conditions, postoperative pain following orthopedic surgery, or acute flare of osteoarthritis and rheumatoid arthritis.

  18. Femur chondrosarcoma misdiagnosed as acute knee arthritis and osteomyelitis--further developing a hitherto unreported complication of tumor embolic ischemic ileal perforation after arthroscopic lavage.

    The differentiation between osteomyelitis and bone tumor may be difficult due to their overlapping clinical and radiological features. A 25-year-old lady presented with left knee pain and joint effusion associated with redness and hotness. A sub-optimally taken plain radiograph showed mixed osteolytic and osteoblastic lesion in the left lower femur with surrounding soft tissue swelling. Since the clinical diagnosis was acute osteomyelitis and arthritis, arthroscopic lavage was performed as a diagnostic and therapeutic procedure. The removed loose bodies and fibrinous tissue showed pathological features suspicious of chondrosarcoma. Subsequent MRI revealed an infiltrative tumor eroding through the cortex and joint cartilage. En bloc excision of the left lower femur, upper tibia including the knee joint and patella was performed, and the final diagnosis was grade 2 chondrosarcoma. The patient developed bilateral pulmonary metastasis 33 months after operation. Five months later, she suffered from a hitherto undescribed complication of ischemic perforation of the terminal ileum secondary to tumor embolic arterial obstruction with no macroscopic intestinal or peritoneal tumor deposit. The patient developed multiple brain metastases and died 43 months after initial presentation. Our case illustrates that malignant bone tumor as a differential diagnosis of acute osteomyelitis and arthritis merits recognition and exclusion before arthroscopic lavage, which may enhance tumor dissemination and in our patient results in embolic ischemic ileal perforation.

    A 38-year-old man presented with a one-month history of muscle weakness and dysesthesia in the lower extremities, urinary retention, and urinary tract infection after lumbar burst fracture resulted from high fall. During the rehabilitation in our hospital, he had arthritis in both the ankle and knee. However, the patient was treated as gouty arthropathy initially. The arthritis was completely remitted in a few days after the patient was diagnosed as reactive arthritis and started with sulfasalazine therapy and there was no recurrence during 4 months of follow-up. Based on this case, early recognition of reactive arthritis is of major importance to avoid delayed initiation of appropriate treatment in the patients with polyarthritis secondary to neurogenic bladder following cauda equina injury after spine fracture.

    Rheumatoid arthritis (RA) is a chronic autoimmune arthritis that affects approximately 1% of the population. Synovial inflammation cannot fully explain the level of pain reported by patients and facilitation of pain processing at the spinal level has been implicated. We characterized the K/BxN serum transfer arthritis model as a model of joint inflammation-induced pain and examine pharmacologic responsiveness and spinal glia activation. Mechanical allodynia developed congruently with joint swelling. Surprisingly, allodynia persisted after resolution of inflammation. At the peak of joint inflammation, (days 4–10) hypersensitivity was attenuated with i.p. etanercept, gabapentin, and ketorolac. Following resolution of synovial inflammation (day 19–28), only gabapentin relieved allodynia. The superficial dorsal horn of arthritic mice displayed increased staining of microglia at early and late time points, but astrocyte staining increased only during the inflammatory phase. ATF3, a marker of nerve injury, was significantly increased in the lumbar dorsal root ganglia during the late phase (day 28). Hence, serum transfer in the K/BxN serum transfer arthritis model produces a persistent pain state, where the allodynia during the inflammatory state is attenuated by TNF and prostaglandin inhibitors, and the pharmacology and histochemistry data suggest a transition from an inflammatory state to a state that resembles a neuropathic condition over time. Therefore, the K/BxN serum transfer model represents a multifaceted model for studies exploring pain mechanisms in conditions of joint inflammation and may serve as a platform for exploring novel treatment strategies for pain in human arthritic conditions. K/BxN serum transfer arthritis produces persistent mechanical hypersensitivity despite resolution of clinical signs with evidence of transition from an inflammatory to neuropathic pain state.

    We investigated the effects of suppression of complement activation at C3 level and inhibition of C5a on acute synovitis in rats. Acute synovitis was induced in Wistar rats by intra-articular (i.a.) injection into one knee of 0.3 mg of MoAb 6D1 (anti-rat CD59 antibody). In the treatment groups, soluble CR1 (sCR1) or C5a receptor (C5aR) antagonist was administered intra-articularly or intravenously and effects on the course of the acute synovitis were monitored. Synovitis induced by 6D1 was characterized by joint swelling, thickening of synovial tissue, cellular infiltration and deposition of membrane attack complex (MAC) on the synovial surface. Neither inflammatory change nor MAC deposition was found in rats which received an i.a. injection of sCR1 to suppress complement activity in the joint. Intra-articular injection of sCR1 did not reduce plasma complement activity. Intravenous administration of sCR1 suppressed plasma complement activity but had no effect on the course of the arthritis and synovitis with MAC deposition was observed. Neither i.a. nor i.v. injection of C5aR antagonist had any suppressive effects on inflammatory change or MAC deposition in synovium. The data show that inflammatory change induced by 6D1 was mediated by local complement activation and was not accompanied by systemic complement activation. C5a generation was not responsible for the observed inflammation, suggesting that other complement activation products, possibly MAC, mediate the inflammatory change observed in this model of acute synovitis in rats.

  9. MyD88-dependent IL-1 receptor signaling is essential for gouty inflammation stimulated by monosodium urate crystals

    While it is known that monosodium urate (MSU) crystals cause the disease gout, the mechanism by which these crystals stimulate this inflammatory condition has not been clear. Here we find that the Toll/IL-1R (TIR) signal transduction adaptor myeloid differentiation primary response protein 88 (MyD88) is required for acute gouty inflammation. In contrast, other TIR adaptor molecules, TIRAP/Mal, TRIF, and TRAM, are not required for this process. The MyD88-dependent TLR1, -2, -4, -6, -7, -9, and -11 and IL-18 receptor (IL-18R) are not essential for MSU-induced inflammation. Moreover, MSU does not stimulate HEK cells expressing TLR1–11 to activate NF-κB. In contrast, mice deficient in the MyD88-dependent IL-1R showed reduced inflammatory responses, similar to those observed in MyD88-deficient mice. Similarly, mice treated with IL-1 neutralizing antibodies also showed reduced MSU-induced inflammation, demonstrating that IL-1 production and IL-1R activation play essential roles in MSU-triggered inflammation. IL-1R deficiency in bone marrow–derived cells did not affect the inflammatory response; however, it was required in non–bone marrow–derived cells. These results indicate that IL-1 is essential for the MSU-induced inflammatory response and that the requirement of MyD88 in this process is primarily through its function as an adaptor molecule in the IL-1R signaling pathway.

    Lyme arthritis results from acute inflammation caused by the spirochete Borrelia burgdorferi. The number of cases per year has been rising since 2006, with a majority of patients being affected in the northeastern United States. Development of Lyme arthritis is of particular importance to the orthopedic surgeon because Lyme arthritis often presents as an acute episode of joint swelling and tenderness and may be confused with bacterial septic arthritis. Considering the vast difference in treatment management between these 2 pathologies, differentiating between them is of critical importance. Septic arthritis often needs to be addressed surgically, whereas Lyme arthritis can be treated with oral antibiotics alone. Laboratory testing for Lyme disease often results in a delay in diagnosis because many laboratories batch-test Lyme specimens only a few times per week because of increased expense. The authors present a case of Lyme arthritis in the pediatric ankle in an endemic region. No clear algorithm exists to delineate between septic arthritis and Lyme arthritis of the joint. Improved clinical guidelines for the identification and diagnosis of Lyme arthritis of the ankle are important so that appropriate antibiotics can be used and surgery can be avoided. PMID:25275987

    Psoriatic arthritis is an inflammatory rheumatic disorder of unknown etiology occurring in patients with psoriasis. The Classification Criteria for Psoriatic Arthritis study group has recently developed a validated set of classification criteria for psoriatic arthritis with a sensitivity of 91.4% and a specificity of 98.7%. Three main clinical patterns have been identified: oligoarticular (≤ 4 involved joints) or polyarticular (≥ 5 involved joints) peripheral disease and axial disease with or without associated peripheral arthritis. In this context distal interphalangeal arthritis and arthritis mutilans may occur. According to other reports, also in our centre, asymmetric oligoarthritis is the most frequent pattern at onset. Axial disease has been estimated between 5% and 36% of patients. It is characterized by an irregular involvement of the axial skeleton with a predilection for the cervical spine. Recurrent episodes of enthesitis and dactylitis represent a hallmark of psoriatic arthritis. In around 20% of cases distal extremity swelling with pitting edema of the hands or feet is observed. Unilateral acute iridocyclitis, usually recurrent in alternate fashion, is the most frequent extra-articular manifestation, and accelerated atherosclerosis is the prominent comorbidity. The clinical course of peripheral and axial psoriatic arthritis is usually less severe than rheumatoid arthritis and ankylosing spondylitis, respectively. Local corticosteroid injections and non-steroidal anti-inflammatory drugs are recommended in milder forms. Sulphasalazine and methotrexate are effective in peripheral psoriatic arthritis. Recent studies have provided evidence on the efficacy of anti-tumor necrosis factor-α drugs to control symptoms and to slow or arrest radiological disease progression. PMID:21199465

    In this review of the 1990 septic arthritis literature, we revisit synovial fluid leukocytosis, examine the utility of synovial fluid glucose and protein measurements, and look at the levels of two cytokines, tumor necrosis factor and interleukin-1, in infected joint fluids. We see the many faces of gonococcal arthritis and the ravages of septic arthritis when the host has rheumatoid arthritis. Should we recommend antibiotic prophylaxis for the rheumatoid patient with a prosthetic joint who is undergoing a procedure that leads to transient bacteremia? What are some of the salient features of septic arthritis when it involves the sternoclavicular or sacroiliac joints? We also look at some unusual microorganisms, eg, group C Streptococcus, Streptococcus viridans, Listeria monocytogenes, Pseudomonas cepacia, Pseudomonas maltophilia, and Neisseria sicca. In patients with acquired immunodeficiency syndrome, we encounter reports of septic arthritis, osteomyelitis, and spinal epidural abscess caused by opportunistic microorganisms. Two unusual sites of infection include the C1-2 lateral facet joint and subacromial bursa without involvement of the glenohumeral joint. Finally, we examine how to drain a septic knee: the orthopedic point of view. PMID:1911055

    The aim of this systematic review and meta-analysis is to assess the efficacy and safety of tofacitinib for the treatment of patients with acute rheumatoid arthritis (RA) who have had an inadequate response to disease-modifying antirheumatic drug (DMARD). Randomized controlled trials were searched in MEDLINE (1966-2013), Embase (1947-2013), the Cochrane Central Register of Controlled Trials (1948-2013), WHO International Clinical Trial Registration Platform (2004-2013), Clinical Trial.gov (1999-2013), and China Biology Medicine disc (1978-2013). The review included 10 studies involving 4,929 patients. A pooled analysis of six studies showed that tofacitinib had a superior effect over placebo (both with background therapy) at weeks 12 and 24. Also, the pooled results of three studies showed that tofacitinib monotherapy had a significantly greater effect over placebo. Compared to adalimumab, tofacitinib was found to be more efficacious as well. For safety, tofacitinib monotherapy had less serious adverse events (sAE) than placebo but not other adverse effects (oAE). In the comparison of tofacitinib and placebo both with background therapy, no difference in sAE and oAE were found. However, the quality of the evidence was quite low when evaluated using GRADE. Tofacitinib alone, or together with non-biologic DMARDs, was associated with more favorable remission in the signs and symptoms of RA than adalimumab or placebo. Also, tofacitinib monotherapy was safer than placebo with regards to reported sAE, but not oAE. However, the quality of evidence is exceedingly low; long-term, large-scale, and high-quality post-marketing research is suggested to further verify the conclusion. PMID:24389749

  6. Prospective surveillance study of acute respiratory infections, influenza-like illness and seasonal influenza vaccine in a cohort of juvenile idiopathic arthritis patients

    2013-01-01

    Background Acute respiratory infections (ARI) are frequent in children and complications can occur in patients with chronic diseases. We evaluated the frequency and impact of ARI and influenza-like illness (ILI) episodes on disease activity, and the immunogenicity and safety of influenza vaccine in a cohort of juvenile idiopathic arthritis (JIA) patients. Methods Surveillance of respiratory viruses was conducted in JIA patients during ARI season (March to August) in two consecutive years: 2007 (61 patients) and 2008 (63 patients). Patients with ARI or ILI had respiratory samples collected for virus detection by real time PCR. In 2008, 44 patients were immunized with influenza vaccine. JIA activity index (ACRPed30) was assessed during both surveillance periods. Influenza hemagglutination inhibition antibody titers were measured before and 30-40 days after vaccination. Results During the study period 105 ARI episodes were reported and 26.6% of them were ILI. Of 33 samples collected, 60% were positive for at least one virus. Influenza and rhinovirus were the most frequently detected, in 30% of the samples. Of the 50 JIA flares observed, 20% were temporally associated to ARI. Influenza seroprotection rates were higher than 70% (91-100%) for all strains, and seroconversion rates exceeded 40% (74-93%). In general, response to influenza vaccine was not influenced by therapy or disease activity, but patients using anti-TNF alpha drugs presented lower seroconversion to H1N1 strain. No significant differences were found in ACRPed30 after vaccination and no patient reported ILI for 6 months after vaccination. Conclusion ARI episodes are relatively frequent in JIA patients and may have a role triggering JIA flares. Trivalent split influenza vaccine seems to be immunogenic and safe in JIA patients.

    We describe the case of a young patient with calcifying encephalopathy, born to asymptomatic parents. An extensive hypothesis-driven etiological assessment was performed and failed to detect the precise etiology during many years. We therefore decided to perform whole exome sequencing of the child-unaffected parents trio. A de novo pathogenic variant in the IFIH1 gene which has recently been shown to cause autosomal dominant forms of Aicardi-Goutières syndrome was identified. This child presented with a severe form with neonatal thrombocytopenia and hepatomegaly, the latter having been detected during late gestation. Although first milestones were uneventful, he progressively lost motor skills from the age of 12 months and developed severe spastic paraplegia. Brain imaging revealed white matter abnormalities and extensive calcifications. He also presented atypical skin lesions, different from chilblains. His medical history was marked by two episodes of acute pancreatitis. We provide herein the results of pathological examination including detailed description of the neuropathological hallmarks. To our knowledge, this the first detailed clinico-pathological description of a patient with an IFIH1 pathogenic variant. © 2016 Wiley Periodicals, Inc. PMID:26833990

    Rheumatoid arthritis (RA) is an autoimmune disease mediated by inflammatory processes mainly at the joints. Recently, awareness of Epstein-Barr virus (EBV)-associated T-cell lymphoproliferative disorder (T-LPD) has been heightened for its association with methotraxate usage in RA patients. In the contrary, acute myeloid leukemia with multilineage dysplasia (AML-MLD) has never been documented to be present concomitantly with the above two conditions. In this report we present a case of an autopsy-proven co-existence of AML-MLD and EBV-associated T-LPD in a patient with RA. PMID:19566938

    We document the case of a 7-year-old boy who presented with pain in his left ear and trismus after a diagnosis of acute otitis media one week previously. His blood inflammatory markers were raised and magnetic resonance imaging (MRI) showed significant left temporomandibular joint effusion and partial attenuation of the left mastoid. A clinical diagnosis of septic arthritis of the TMJ was made and the patient was commenced on broad-spectrum antibiotics. Analysis using real time PCR enabled identification of the offending organism, confirmation of the diagnosis and antibiotic treatment to be specifically tailored for treatment. PMID:26340928

    Aicardi-Goutières syndrome (AGS) is a rare, genetically determined early-onset progressive encephalopathy. To date, mutations in six genes have been identified as etiologic for AGS. Our Japanese nationwide AGS survey identified six AGS-affected individuals without a molecular diagnosis; we performed whole-exome sequencing on three of these individuals. After removal of the common polymorphisms found in SNP databases, we were able to identify IFIH1 heterozygous missense mutations in all three. In vitro functional analysis revealed that IFIH1 mutations increased type I interferon production, and the transcription of interferon-stimulated genes were elevated. IFIH1 encodes MDA5, and mutant MDA5 lacked ligand-specific responsiveness, similarly to the dominant Ifih1 mutation responsible for the SLE mouse model that results in type I interferon overproduction. This study suggests that the IFIH1 mutations are responsible for the AGS phenotype due to an excessive production of type I interferon. PMID:24995871

    The aim of this study was to observe the effects of uric acid lowering therapy (UALT), febuxostat and allopurinol, on blood pressure (BP) and serum creatinine level. Post-hoc data were derived from a phase-III, randomised, double-blind, 4-week trial of male gouty patients that compared the safety and efficacy of febuxostat and allopurinol in adults with gout. The subjects were randomly assigned to one of five groups, 35-37 in each group (febuxostat: 40, 80, 120 mg/d; allopurinol: 300 mg/d; control group: placebo). Blood pressure and serum creatinine level were measured at baseline and at weeks 2 and 4. Diastolic BP and creatinine level had decreased significantly in the UALT groups compared to the control group at week 4. Diastolic BP had decreased significantly in the allopurinol group and serum creatinine level had decreased significantly in the febuxostat groups at week 4. After adjusting for confounding variables, serum uric acid changes were found to be significantly correlated with changes in serum creatinine level but were not associated with changes in systolic or diastolic BP. UALT in gouty subjects significantly decreased diastolic BP and serum creatinine level. Changes in uric acid were significantly correlated with those in serum creatinine level, suggesting the feasibility of renal function improvement through UALT in gouty men. PMID:25120316

    Midfoot arthritis is a common cause of significant pain and disability. Although the medial tarsometatarsal (TMT) joints provide < 7 degrees of sagittal plane motion, the more mobile lateral fourth and fifth TMT joints provide balance and accommodation on uneven ground. These small constrained TMT joints also provide stability and translate the forward propulsion motion of the hindfoot and ankle joint to the forefoot metatarsophalangeal joints from heel rise to toe-off. Posttraumatic degeneration is the primary cause of midfoot arthritis, although primary degeneration and inflammatory conditions can also affect this area. The result is a painful midfoot that can no longer effectively transmit load from the hindfoot to the forefoot. Shoe modifications and orthotic inserts are the mainstay of nonsurgical management. Successful management of midfoot arthritis with orthoses is predicated on achieving adequate joint stabilization while still allowing function. Surgical intervention typically involves arthrodesis of the medial midfoot, although the best treatment of the more mobile lateral column is a subject of debate. PMID:20595134

    Polymorphonuclear leucocyte (PMN) functions (migration in vitro, chemiluminescence, O-2 production, binding of chemotactic peptide, and aggregation) were studied in HLA-B27 positive patients with previous yersinia arthritis (YA). PMNs of patients whose disease had been severe showed chemokinetic and chemiluminescence responses significantly higher than the PMNs of those with a mild disease. The results support the view that enhanced PMN function contributes to inflammatory symptoms in patients with YA. PMID:3592787

    Aicardi-Goutières syndrome (AGS) is a genetic encephalopathy whose clinical features mimic those of acquired in utero viral infection. AGS exhibits locus heterogeneity, with mutations identified in genes encoding the 3′→5′ exonuclease TREX1 and the three subunits of the RNASEH2 endonuclease complex. To define the molecular spectrum of AGS, we performed mutation screening in patients, from 127 pedigrees, with a clinical diagnosis of the disease. Biallelic mutations in TREX1, RNASEH2A, RNASEH2B, and RNASEH2C were observed in 31, 3, 47, and 18 families, respectively. In five families, we identified an RNASEH2A or RNASEH2B mutation on one allele only. In one child, the disease occurred because of a de novo heterozygous TREX1 mutation. In 22 families, no mutations were found. Null mutations were common in TREX1, although a specific missense mutation was observed frequently in patients from northern Europe. Almost all mutations in RNASEH2A, RNASEH2B, and RNASEH2C were missense. We identified an RNASEH2C founder mutation in 13 Pakistani families. We also collected clinical data from 123 mutation-positive patients. Two clinical presentations could be delineated: an early-onset neonatal form, highly reminiscent of congenital infection seen particularly with TREX1 mutations, and a later-onset presentation, sometimes occurring after several months of normal development and occasionally associated with remarkably preserved neurological function, most frequently due to RNASEH2B mutations. Mortality was correlated with genotype; 34.3% of patients with TREX1, RNASEH2A, and RNASEH2C mutations versus 8.0% RNASEH2B mutation–positive patients were known to have died (P=.001). Our analysis defines the phenotypic spectrum of AGS and suggests a coherent mutation-screening strategy in this heterogeneous disorder. Additionally, our data indicate that at least one further AGS-causing gene remains to be identified. PMID:17846997

    The study analyzed serum hyaluronidase and deoxyribonuclease activity in patients with early arthritis--early rheumatoid arthritis and acute reactive arthritis. The criteria of their differential diagnostics were developed on the basis of data obtained. The genuine methods were applied to analyze hyaluronidase and deoxyribonuclease activity of blood serum based on formation of clot of etacridine acetate (rivanol) with hyaluronic acid and DNA inversely proportionally to their polymerization under the impact of enzymes. The increased serum hyaluronidase and deoxyribonuclease activity was established in patients with early arthritis as compared with control group (p < 0.001). The prevalence of mentioned types of activity under early rheumatoid arthritis as compared with acute reactive arthritis was detected too. The rests for differentiate diagnostics of early rheumatoid arthritis and acute reactive arthritis were developed conformed to criteria of the most useful diagnostic tests in rheumatology.

    The menstrual cycle is characterised by variations in the absolute and relative concentrations of the hormones of the hypothalamic pituitary ovarian axis, which in turn affect cell function and cytokine and heat shock protein production. Menstruation involves the shedding of the secretory endometrium, which is part of the mucosal associated lymphoid tissue and hence is rich in immunologically competent cells such as CD8 T cells and macrophages. The case is reported here of a patient presenting with a recurrent but transient symmetrical inflammatory polyarthritis which only occurred at menstruation with no residual damage. The disease was suppressed by danazol. Endometrial degradation products are suggested as the trigger of this 'menstrual arthritis'. PMID:8427519

    Summary Cutaneous lesions described as chilblain lupus occur in the context of familial chilblain lupus or Aicardi–Goutières syndrome. To date, seven genes related to Aicardi–Goutières syndrome have been described. The most recently described encodes the cytosolic double-stranded RNA receptor IFIH1 (also known as MDA5), a key component of the antiviral type I interferon-mediated innate immune response. Enhanced type I interferon signalling secondary to gain-of-function mutations in IFIH1 can result in a range of neuroinflammatory phenotypes including classical Aicardi–Goutières syndrome. It is of note that none of the patients with a neurological phenotype so far described with mutations in this gene was reported to demonstrate cutaneous involvement. We present a family segregating a heterozygous pathogenic mutation in IFIH1 showing dermatological involvement as a prominent feature, variably associated with neurological disturbance and premature tooth loss. All three affected individuals exhibited increased expression of interferon-stimulated genes in whole blood, and the mutant protein resulted in enhanced interferon signalling in vitro, both in the basal state and following ligand stimulation. Our results further extend the phenotypic spectrum associated with mutations in IFIH1, indicating that the disease can be confined predominantly to the skin, while also highlighting phenotypic overlap with both Aicardi–Goutières syndrome and Singleton–Merten syndrome.

  12. Gait changes precede overt arthritis and strongly correlate with symptoms and histopathological events in pristane-induced arthritis

    PubMed Central

    2010-01-01

    Introduction Pristane-induced arthritis (PIA) in the rat has been described as an animal model of inflammatory arthritis which exhibits features similar to rheumatoid arthritis in humans, such as a chronic, destructive, and symmetrical involvement of peripheral joints. However, so far little is known about the earliest inflammatory events and their influence on locomotor behaviour during the course of PIA. To investigate this issue a detailed analysis of the pathologic changes occurring during the prodromal and early stages of PIA was performed. Methods Arthritis was induced in DA.rats by injection of 150 μl 2,6,10,4-tetramethyl-pentadecane (pristane) at the base of the tail and changes in locomotor behaviour of the affected paws were monitored using the CatWalk quantitative gait analysis system. The pathologic events occurring in the joints of pristane-injected animals were studied before onset, at onset, and during acute phase of arthritis by histological methods. Results Gait analysis revealed that changes in locomotion such as reduced paw print areas and stance phase time are already apparent before the onset of clinically discernible arthritis symptoms (erythema, paw swelling) and correlate with PIA scores. In agreement with these findings, inflammatory tenosynovitis could be observed by histology already before the onset of erythema and swelling of the respective paws. In the most heavily affected rats also irregularities in step sequence patterns occurred A kinetic analysis of clinical and histological findings demonstrated that gait changes precede the pathological changes occurring during the acute phase of pristane-induced arthritis. Conclusions Gait analysis allows for pinpointing the initial inflammatory changes in experimental arthritis models such as pristane-induced arthritis. Analysis of early clinically relevant symptoms in arthritis models may facilitate the search for novel therapeutics to interfere with pain, inflammation and joint destruction

    The authors studied the histopathologic evolution of arthritis in nonirradiated and irradiated hamsters infected with Borrelia burgdorferi. Nonirradiated hamsters injected in the hind paws with B. burgdorferi developed an acute inflammatory reaction involving the synovium, periarticular soft tissues, and dermis. This acute inflammatory reaction was short-lived and was replaced by a mild chronic synovitis as the number of detectable spirochetes in the synovium, periarticular soft tissues, and perineurovascular areas diminished. Exposing hamsters to radiation before inoculation with B. burgdorferi exacerbated and prolonged the acute inflammatory phase. Spirochetes also persisted longer in the periarticular soft tissues. A major histopathologic finding was destructive and erosive bone changes of the hind paws, which resulted in deformation of the joints. These studies should be helpful in defining the immune mechanism participating in the onset, progression, and resolution of Lyme arthritis.

    Adenosine deaminases acting on RNA (ADARs) catalyze the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) and thereby potentially alter the information content and structure of cellular RNAs. Notably, although the overwhelming majority of such editing events occur in transcripts derived from Alu repeat elements, the biological function of non-coding RNA editing remains uncertain. Here, we show that mutations in ADAR1 (also known as ADAR) cause the autoimmune disorder Aicardi-Goutières syndrome (AGS). As in Adar1-null mice, the human disease state is associated with upregulation of interferon-stimulated genes, indicating a possible role for ADAR1 as a suppressor of type I interferon signaling. Considering recent insights derived from the study of other AGS-related proteins, we speculate that ADAR1 may limit the cytoplasmic accumulation of the dsRNA generated from genomic repetitive elements.

    Background To facilitate the development of therapies for rheumatoid arthritis (RA), the Innovative Medicines Initiative BTCure has combined the experience from several laboratories worldwide to establish a series of protocols for different animal models of arthritis that reflect the pathogenesis of RA. Here, we describe chronic pristane-induced arthritis (PIA) model in DA rats, and provide detailed instructions to set up and evaluate the model and for reporting data. Methods We optimized dose of pristane and immunization procedures and determined the effect of age, gender, and housing conditions. We further assessed cage-effects, reproducibility, and frequency of chronic arthritis, disease markers, and efficacy of standard and novel therapies. Results Out of 271 rats, 99.6% developed arthritis after pristane-administration. Mean values for day of onset, day of maximum arthritis severity and maximum clinical scores were 11.8±2.0 days, 20.3±5.1 days and 34.2±11 points on a 60-point scale, respectively. The mean frequency of chronic arthritis was 86% but approached 100% in long-term experiments over 110 days. Pristane was arthritogenic even at 5 microliters dose but needed to be administrated intradermally to induce robust disease with minimal variation. The development of arthritis was age-dependent but independent of gender and whether the rats were housed in conventional or barrier facilities. PIA correlated well with weight loss and acute phase reactants, and was ameliorated by etanercept, dexamethasone, cyclosporine A and fingolimod treatment. Conclusions PIA has high incidence and excellent reproducibility. The chronic relapsing-remitting disease and limited systemic manifestations make it more suitable than adjuvant arthritis for long-term studies of joint-inflammation and screening and validation of new therapeutics.

    The role of trace elements bound to proteins in the etiology and pathogenesis of rheumatoid arthritis (RA) remains unclear. In this sense, the identification and detection of metalloproteins has a strong and growing interest. Metalloprotein studies are currently carried out by polyacrylamide gel electrophoresis (PAGE) associated to inductively coupled plasma mass spectrometry (ICPMS), and despite that complete information can be obtained for metals such as Fe, Cu and Zn, difficulties due to poor sensitivity for other trace elements such as Sn, As, etc, are currently faced. In the present work, a simple and fast method for the determination of trace metals bound to synovial fluid (SF) proteins was optimized. Proteins from SF (long and short-term RA) were separated in ten fractions by native PAGE, then dissolved in nitric acid and peroxide hydrogen, and analyzed by ICPMS. Fifteen metals were determined in each separated protein fraction (band). Adequate calibration of proteins molecular weight allowed stablishing which protein type were bound to different metals.

    The goal of the work described here was to evaluate the role of virtual touch tissue quantification (VTQ) combined with urinary β2-microglobulin (β2-MG) measurement in the early diagnosis of gouty kidney damage. Two hundred fifty-nine patients with gouty kidney damage and 200 healthy control subjects were tested. The shear wave velocity (SWV) of the renal parenchyma and sinus as determined with VTQ and the urinary β2-MG level of the two groups were analyzed. Although there were no significant differences in age, body mass index, creatinine level and blood urea nitrogen between the two groups (all p's > 0.05), the aforementioned parameters were higher in the group with gouty kidney damage than in the control group. Urinary β2-MG levels of the patients with kidney damage were significantly higher than those of the control subjects (t = 6.38, p < 0.01). The SWV of the renal parenchyma was higher than that of the sinus in both groups. Compared with controls, patients with kidney damage had significantly increased renal parenchyma and sinus SWVs (all p-values < 0.05). Urinary β2-MG level was positively linearly correlated with the SWV of renal parenchyma in patients with kidney damage (r = 0.442, p < 0.0001). However, there was no correlation between urinary β2-MG level and the SWV of the sinus in patients with kidney damage (r = 0). In the control group, there was no correlation between urinary β2-MG level and the SWV of the renal parenchyma or sinus. The elasticity of the kidney as determined with VTQ, combined with the urinary β2-MG level, may be helpful in the early diagnosis of gouty kidney damage. PMID:24642221

    The pathological invasion of a joint and subsequent inflammation is known as septic arthritis. The knee and hip are the most frequently involved joints. Staphylococcus aureus is the most common cause of septic arthritis in children. An acute onset of illness with an inflamed painful joint and restricted movements and inability to use joint (pseudoparalysis) clinically indicates septic arthritis. The diagnosis is difficult in a neonate or young child where refusal to feed, crying, discomfort during change of diaper (if hip is involved) or attempted joint movement may be the only findings. Fever and other systemic signs may also be absent in neonates. Septic arthritis is diagnosed clinically, supported by appropriate radiological and laboratory investigations. The peripheral blood white cell count is frequently raised with a predominance of polymorphonuclear cells. The acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often markedly raised. Ultrasonography and MRI are preferred investigations in pediatric septic arthritis. Determination of infecting organism in septic arthritis is the key to the correct antibiotic choice, treatment duration and overall management. Joint aspirate and/or blood culture should be obtained before starting antibiotic treatment. Several effective antibiotic regimes are available for managing septic arthritis in children. Presence of large collections, thick pus, joint loculations and pus evacuating into surrounding soft tissues are main indications for surgical drainage. Joint aspiration can be a practical alternative in case the lesion is diagnosed early, with uncomplicated presentations and superficial joints. PMID:26189923

    It has been postulated that TNF has a pivotal role in a cytokine cascade that results in joint inflammation and destruction in rheumatoid arthritis (RA). To evaluate this, we examined the response of TNF-deficient (Tnf(-/-)) mice in two models of RA. Collagen-induced arthritis (CIA) was induced by injection of chick type II collagen (CII) in CFA. Tnf(-/-) mice had some reduction in the clinical parameters of CIA and, on histology, significantly more normal joints. However, severe disease was evident in 54% of arthritic Tnf(-/-) joints. Tnf(-/-) mice had impaired Ig class switching, but preserved T cell proliferative responses to CII and enhanced IFN-gamma production. Interestingly, CII-immunized Tnf(-/-) mice developed lymphadenopathy and splenomegaly associated with increased memory CD4(+) T cells and activated lymph node B cells. Acute inflammatory arthritis was also reduced in Tnf(-/-) mice, although again some mice exhibited severe disease. We conclude that TNF is important but not essential for inflammatory arthritis; in each model, severe arthritis could proceed even in the complete absence of TNF. These results call into doubt the concept that TNF is obligatory for chronic autoimmune and acute inflammatory arthritis and provide a rationale for further studies into TNF-independent cytokine pathways in arthritis.

    OBJECTIVES—Reactive joint complications triggered by salmonella gastroenteritis are increasingly reported, but the outcome and long term prognosis of the patients is incompletely known. This study looked at the prognosis of salmonella arthritis in patients hospitalised in 1970-1986.
METHODS—Hospital records from two hospitals in southern Finland were screened for patients with the discharge diagnosis of salmonellosis or reactive, postinfectious arthritis or Reiter's disease. For the patients with confirmed diagnosis of reactive salmonella arthritis, data about the acute disease were collected from the hospital records. A follow up study was performed.
RESULTS—There were 63 patients (28 women, 35 men, mean age 36.5 years) with salmonella arthritis. Urethritis occurred in 27%, eye inflammation in 13%, and low back pain in 44% of the patients. HLA-B27 was present in 88%. More men than women were HLA-B27 positive. HLA-B27 positive patients had higher erythrocyte sedimentation rate (mean 80.9 v 46.5 mm 1st h, p = 0.0180). Also, extra-articular features and radiological sacroiliitis were seen only in HLA-B27 positive patients. A follow up study was performed on 50 patients mean 11.0 (range 5-22 years) later. Twenty patients had recovered completely. Ten patients had mild joint symptoms, 11 patients had had a new acute transient arthritis, and five acute iritis. Eight patients had developed chronic spondyloarthropathy. Radiological sacroiliitis was seen in six of 44 patients, more frequently in male than in female patients (32% v 0%; p = 0.0289). Recurrent or chronic arthritis, iritis or radiological sacroiliitis developed only in HLA-B27 positive patients.
CONCLUSION—Joint symptoms are common after reactive salmonella arthritis. HLA-B27 contributes to the severity of acute disease and to the late prognosis.

    2016-01-01

    Septic arthritis of the temporomandibular joint (TMJ) is a rare disease. The most common symptoms of this disease are acute malocclusion, limited mouth opening, swelling, and tenderness of affected TMJ. These symptoms are often confused with internal derangement of the articular disc, rheumatoid arthritis, retrodiscitis, or osteoarthritis. Therefore, differential diagnosis by image examination is required. Usually, antimicrobial treatment and surgical drainage by needle aspiration, arthroscopy, or arthrotomy are effective treatment approaches. In this study, a patient who was diagnosed with septic arthritis was treated with arthrocentesis and antibiotics without significant complications. We present a case report with a review of the literature. PMID:27595091

    2006-07-01

    Reactive arthritis is an important cause of lower limb oligoarthritis, mainly in young adults. It is one of the spondyloarthropathy family; it is distinguishable from other forms of inflammatory arthritis by virtue of the distribution of affected sites and the high prevalence of characteristic extra-articular lesions. Many terms have been used to refer to this and related forms of arthritis leading to some confusion. Reactive arthritis is precipitated by an infection at a distant site and genetic susceptibility is marked by possession of the HLA-B27 gene, although the mechanism remains uncertain. Diagnosis is a two stage process and requires demonstration of a temporal link with a recognised "trigger" infection. The identification and management of "sexually acquired" and "enteric" forms of reactive arthritis are considered. Putative links with HIV infection are also discussed. The clinical features, approach to investigation, diagnosis, and management of reactive arthritis are reviewed. PMID:16822921

    Tumour necrosis factor-alpha (TNF-alpha) is involved in diverse biological processes including immune and inflammatory reactions and the response to surgical stress. Two soluble TNF receptor protein fragments, TNF-sR55 (from the p55 kD TNF receptor) and TNF-sR75 (from the p75 kD TNF receptor), are released by cells during inflammation and may modulate the e effects of TNF-alpha. We have studied the kinetics of secretion of TNF-alpha, TNF-sR55 and TNF-sR75 in the sera of patients with rheumatoid arthritis (RA) and control subjects with osteoarthritis (OA) or chronic osteomyelitis (OM) before and after major surgery. Significantly higher pre-operative levels of TNF-sR55 and TNF-sR75 were found in RA and OM as compared with OA (P < 0.02). Following surgery, TNF-sR55 increased within 24 h in RA, OM and OA (P < 0.05), whereas TNF-sR75 increased significantly only in OM and OA patients (P < 0.05). By contrast, no TNF-alpha was detectable before and after surgery in any of the subjects, but this may have been due to impaired detection (by ELISA) of TNF-alpha when it is bound to TNF-sR. These findings suggest that TNF-sR55 and TNF-sR75 may be further markers of the host's reaction to inflammatory insults. They may also play a role in modulating the immune and inflammatory reactions by inhibiting the systemic effects of TNF-alpha. PMID:8385584

    Arthritis of the hallux metatarsophalangeal joint is a common disorder that affects shoewear, ambulation, and other activities of daily living. Etiologies include degenerative arthritis (hallux rigidus), crystal induced arthropathy (gout, pseudogout), rheumatoid arthritis, the seronegative spondyloathropathies, posttraumatic degeneration, and advanced hallux valgus. Accurate diagnosis and selection of the appropriate intervention depends on recognition of pertinent clinical and radiographic features. This study presents a synopsis of the senior author's (LCS) experience with 439 surgically treated patients with hallux metatarsophalangeal arthritis, focusing on origin and treatment. PMID:9584362

    The purpose of this study was to review the data on the etiology, risk factors, clinical presentations, and diagnosis of acute sacroiliitis. A Pubmed search utilizing the indexing term "acute sacroiliitis" was conducted and the data pertinent to the aim of the review was extracted and organized in accordance with the preplanned structure of the manuscript. The diagnosis of acute sacroiliitis is often challenging because of both the relative rarity of this presentation and diverse character of acute sacroiliac pain, frequently mimicking other, more prevalent disorders. Technetium bone scintigraphy can localize the disease process to the sacroiliac joint, while computed tomography or magnetic resonance imaging can be used for the detailed characterization and the extent of the disease as well as the diagnosis of complications. Pyogenic sacroiliitis is by far the most common cause of acute sacroiliitis. Brucellosis, acute sacroiliitis in the course of reactive arthritis, and crystalline-induced sacroiliitis frequently imitate pyogenic sacroiliitis. Acute sacroiliitis can rarely be also related to hematological malignancies or treatment with isotretinoin. Awareness to the possibility of acute sacroiliitis and a thorough physical examination are the necessary prerequisites to its timely diagnosis, while the appropriate laboratory and imaging studies should confirm the precise diagnosis and direct the appropriate treatment strategy.

    Aicardi–Goutières syndrome (AGS) is a severe childhood inflammatory disorder that shows clinical and genetic overlap with systemic lupus erythematosus (SLE). AGS is thought to arise from the accumulation of incompletely metabolized endogenous nucleic acid species owing to mutations in nucleic acid-degrading enzymes TREX1 (AGS1), RNase H2 (AGS2, 3 and 4), and SAMHD1 (AGS5). However, the identity and source of such immunogenic nucleic acid species remain undefined. Using genome-wide approaches, we show that fibroblasts from AGS patients with AGS1-5 mutations are burdened by excessive loads of RNA:DNA hybrids. Using MethylC-seq, we show that AGS fibroblasts display pronounced and global loss of DNA methylation and demonstrate that AGS-specific RNA:DNA hybrids often occur within DNA hypomethylated regions. Altogether, our data suggest that RNA:DNA hybrids may represent a common immunogenic form of nucleic acids in AGS and provide the first evidence of epigenetic perturbations in AGS, furthering the links between AGS and SLE.

    In humans, loss of function mutations in the SAMHD1 (AGS5) gene cause a severe form of Aicardi-Goutières syndrome (AGS), an inherited inflammatory-mediated encephalopathy characterized by increased type I IFN activity and upregulation of IFN-stimulated genes (ISGs). In particular, SAMHD1-related AGS is associated with a distinctive cerebrovascular pathology that commonly leads to stroke. Although inflammatory responses are observed in immune cells cultured from Samhd1 null mouse models, these mice are physically healthy, specifically lacking a brain phenotype. We have investigated the use of zebrafish as an alternative system for generating a clinically relevant model of SAMHD1-related AGS. Using temporal gene knockdown of zebrafish samhd1, we observe hindbrain ventricular swelling and brain hemorrhage. Furthermore, loss of samhd1 or of another AGS-associated gene, adar, leads to a significant upregulation of innate immune-related genes and an increase in the number of cells expressing the zebrafish type I IFN ifnphi1. To our knowledge, this is the first example of an in vivo model of AGS that recapitulates features of both the innate immune and neurological characteristics of the disease. The phenotypes associated with loss of samhd1 and adar suggest a function of these genes in controlling innate immune processes conserved to zebrafish, thereby also contributing to our understanding of antiviral signaling in this model organism.

    Immunosuppressants have been the mainstay of treatment for certain inflammatory joint conditions for many years. Developments in this field, namely biological treatments, have led to a change in the classical presentation of acute bone, joint and soft tissue infections. The normal findings of severe pain and tenderness on examination may be absent or simply mimic a typical exacerbation of the chronic joint condition. A minimally raised white cell count and elevated C-reactive protein in the absence of systemic signs of infection may be interpreted as further evidence for the diagnosis of an exacerbation of inflammatory arthritis. We present a unique case of recurrent polyarticular septic arthritis in a patient treated with immunosuppression for refractory rheumatoid arthritis. We hope this article will enable doctors to appreciate and recognise the changing face of septic arthritis in the modern era of immunosuppressant treatments. PMID:24780657

    Meningococcal outbreaks are a major health concern in Delhi and adjoining regions. Besides acute pyogenic meningitis, meningococcal disease can also manifest as vasculitis, dermatitis and arthritis. To study the frequency, characteristics and long-term outcome of joint involvement in May 2005 meningococcal outbreak in New Delhi, 24 patients with proven meningococcal disease admitted to the hospital from May, 2005 through August, 2005 were studied for occurrence and outcome of joint involvement, and were followed up and evaluated for any complications. The frequency of arthritis was found to be 20%, which is much higher than reported. Diplococci could be identified in the joint aspirate of all 5 patients who developed arthritis. All patients had features of acute septic arthritis which healed without residual deformity following arthrotomy. A significant percentage of patients can still be expected to develop acute septic arthritis in an outbreak of meningococcal meningitis, and a high index of suspicion should be kept for the same. Prompt diagnosis and management will lead to healing without complications in most cases. PMID:19810382

    Rheumatoid arthritis (RA) leads to a progressive weakening of the skeleton which may result in bone fractures. However, spontaneous fractures (exclusive of stress fractures, vertebral collapse, and superficial articular fragmentation) in patients with rheumatoid arthritis have been only occasionally reported in the medical literature. A case of spontaneous talar and calcaneal fracture in rheumatoid arthritis is described. Bone lesions were identified on radiographs, MR images and scintigraphy in a patient with right ankle pain. The absence of episodes of acute trauma, and the presence of acute clinical manifestations should guide the clinical suspicion. PMID:22470803

    2011-01-01

    Introduction The revised shared epitope (SE) concept in rheumatoid arthritis (RA) is based on the presence (S) or absence (X) of the SE RAA amino acid motif at positions 72 to 74 of the third hypervariable region of the various human leucocyte antigen (HLA)-DRB1 alleles. The purpose of this study was to investigate SE subtypes on the basis of the American College of Rheumatology 1987 revised criteria for the classification of RA in a cohort of South African RA patients (n = 143) and their association with clinical and circulating biomarkers of disease activity (autoantibodies, acute phase reactants and cytokines). Methods Genomic DNA was analysed using high-resolution recombinant sequence-specific oligonucleotide PCR typing of the HLA-DRB1 allele. Subtypes of the SE were classified according to the amino acids at positions 72 to 74 for the RAA sequence, and further sub-divided according to the amino acids at positions 70 and 71, which either contribute to (S2, S3P), or negate (S1, S3D) RA susceptibility. Disease activity was assessed on the basis of (1) Disease Activity Score in 28 joints using C-reactive protein (CRP), (2) rheumatoid factor (RF), (3) CRP and (4) serum amyloid A by nephelometry, anticyclic citrullinated peptide antibodies (aCCP) by an immunofluorometric procedure, and cytokines by multiplex bead array technology. Results Of the 143 RA patients, 81 (57%) were homozygous (SS) and 50 (35%) were heterozygous (SX) for the SE alleles with significant overexpression of S2 and S3P (respective odds ratios (ORs) 5.3 and 5.8; P < 0.0001), and 12 (8%) were classified as no SE allele (XX). Both the SS and SX groups showed a strong association with aCCP positivity (OR = 10.2 and P = 0.0010, OR = 9.2 and P = 0.0028, respectively) relative to the XX group. Clinical scores and concentrations of the other biomarkers of disease activity (RF, CRP and T helper cell type 1 (Th1), Th2, macrophage and fibroblast cytokines) were also generally higher in the SS group than

    In studies of experimental Lyme disease, a major obstacle has been the unavailability of a suitable animal model. We found that irradiated LSH/Ss Lak hamsters developed arthritis after injection of Borrelia burgdorferi in the hind paws. When nonirradiated hamsters were injected in the hind paws with B. burgdorferi, acute transient synovitis was present. A diffuse neutrophilic infiltrate involved the synovia and periarticular structures. The inflammation was associated with edema, hyperemia, and granulation tissue. Numerous spirochetes were seen in the synovial and subsynovial tissues. The histopathologic changes were enhanced in irradiated hamsters. The onset and duration of the induced swelling were dependent on the dose of radiation and the inoculum of spirochetes. Inoculation of irradiated hamsters with Formalin-killed spirochetes or medium in which B. burgdorferi had grown for 7 days failed to induce swelling. This animal model should prove useful for studies of the immune response to B. burgdorferi and the pathogenesis of Lyme arthritis.

    Reactive arthritis is an inflammatory joint disease induced by a preceding, sometimes asymptomatic bacterial infection outside the joints. With an estimated prevalence of 40/100,000 inhabitants, the disease primarily affects adults between the ages of 20 and 40 years. The clinical presentation is typically characterized by monoarthritis to oligoarthritis of the lower extremities with possible accompanying enthesitis, bursitis, tenosynovitis, sacroiliitis, dactylitis and rare extra-articular manifestations. Because of the similar clinical symptoms and an association with HLA-B27, reactive arthritis is attributed to the spondyloarthropathies. Typical triggering pathogens are Chlamydia, Salmonella, Yersinia, Shigella and Campylobacter. In about 20% of the cases the usually self-limiting disease becomes chronic. The pathogenesis is not yet understood in detail but it is currently assumed that the intracellular persistence of the pathogen causes an immune reaction resulting in arthritis. Common international diagnostic criteria do not yet exist; therefore the diagnosis is made largely on the basis of clinical findings, medical history and the direct and/or indirect pathogen detection. Several therapeutic options are used to treat reactive arthritis. Ongoing extra-articular infections, with the exception of enteritis should be treated with antibiotics. Besides symptom-orientated treatment of acute arthritis, in prolonged and chronic reactive arthritis an immunomodulatory therapy with steroids, sulfasalazine or methotrexate is used. The role of long-term antibiotic therapy for eradication of persistent intra-articular pathogens in chronic cases is the subject of current research. PMID:24337200

    We report a case of septic arthritis caused by a Bacillus species, B. pumilus, occurring in a healthy child. This organism rarely causes serious infections and has only been described in newborns and immunocompromised individuals or as a skin infection. This child developed an indolent joint swelling after a minor skin injury, and symptoms were initially thought most consistent with chronic arthritis. The case demonstrates that clinicians should consider joint infection in children presenting with acute monoarticular swelling, even without prominent systemic features. PMID:27366165

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease of unclear etiology that is manifested in by a progressive and destructive polyarthritis in association with serological evidence of autoreactivity. Its diagnosis is based on the classification criteria that involve four parameters: joint involvement, serology (rheumatoid factor and anti-cyclic citrullinated peptide--anti-CCP), levels of acute phase reactants and the duration of the symptoms Aletaha, et al. [1]. This classification simplifies the categorization of the patients with early RA; however, the diagnosis requires highly trained specialists who are able to differentiate early symptoms of RA from other pathologies.

    2007-09-01

    Psoriatic arthritis (PsA) is a common unique form of inflammatory arthritis associated with psoriasis. Its exact prevalence is unknown but 5-30% of the 2-3% of subjects of the general population affected with psoriasis are developing PsA. Typically PsA presents as an oligoarticular asymmetrical arthritis with predominant distal finger joint pattern, presence of spinal involvement enthesitis and dactylitis. There is evidence that T-cells play a key role in the immunopathology of PsA as well as Psoriasis. Leflunomide, a selective pyrimidine synthesis inhibitor with the property to inhibit T-cell activation and proliferation has been shown to improve both joint and skin symptoms in patients with PsA. Significant response rates have been observed for Psoriatic Arthritis Response Criteria (PsARC), modified ACR20 and PASI 50 after 24 weeks of treatment with 20 mg/d Leflunomide orally in a randomised, placebo controlled multicenter trial (TOPAS Study). Leflunomide treatment also improved quality of life and showed a favourable safety profile. It is therefore concluded that Leflunomide offers an efficacious, well tolerated, safe, and relatively inexpensive therapeutic option for the treatment of actively inflamed joints and psoriatic skin lesions in patients with PsA.

Known to be present in Fiessinger-Leroy-Reiter syndrome and psoriasis arthropatica, this skin disease has been classified by Japanese authors as a new nosological entity: pustular osteo-arthritis. Pustulosis palmaris et plantaris seems to represent a meeting point for axial rheumatisms close to ankylozing spondylitis. PMID:3563169

    Objective We have shown in vitro and in vivo that osteoclast maturation requires calcium-release activated calcium (CRAC) channels. In inflammatory arthritis, osteoclasts mediate severe and debilitating bone erosion. In the current study, we assess the value of CRAC channels as a therapeutic target to suppress bone erosion in acute inflammatory arthritis. Methods Collagen-induced arthritis (CIA) was induced in mice. The CRAC channel inhibitor 3,4-dichloropropionaniline (DCPA) and a placebo was administered 1 day prior to collagen II booster to induce arthritis. Effects on swelling, inflammatory cell invasion in joints, serum cytokines and bone erosion were measured. Results Assays, by blinded observers, of arthritis severity showed that DCPA, 21 mg/kg/day, suppressed arthritis development over 3 weeks. Bone and cartilage damage in sections of animal feet was reduced approximately 50%; overall swelling of joints was reduced by a similar amount. Effects on bone density by µCT showed clear separation in DCPA-treated CIA animals from CIA without treatment, while differences between controls without CIA and CIA treated with DCPA differed by small amounts and in most cases were not statistically different. Response was not related to anticollagen titres. There were no adverse effects in the treated group on animal weight or activity, consistent with low toxicity. The effect was maximal 12–17 days after collagen booster, during the rapid appearance of arthritis in untreated CIA. At 20 days after treatment (day 40), differences in arthritis score were reduced and tumour necrosis factor α, interleukin (IL)-1, or IL-6 in the serum of the animals were similar in treated and untreated animals. Conclusions DCPA, a novel inhibitor of CRAC channels, suppresses bone erosion associated with acute arthritis in mice and might represent a new treatment modality for acute arthrits. PMID:26819750

    Primary arthritis of chondrosternal joint is very rare and occurs in infants less than 18 months of age. Presentation is most often subacute but may be acute. Child presents with a parasternal mass with history of fever and/or local signs of infection. Clinical symptoms vary from a painless noninflammatory to a painful mass with local tenderness and swelling, while fever may be absent. Laboratory data show low or marginally raised levels of white blood cells and C-reactive protein, reflecting, respectively, the subacute or acute character of the infection. It is a self-limiting affection due to the adequate immune response of the patient. Evolution is generally good without antibiotherapy with a progressive spontaneous healing. A wait-and-see approach with close follow-up in the first weeks is the best therapeutic option. PMID:25386377

    Aicardi-Goutières syndrome (AGS) is a rare, autosomal recessively inherited, immune-mediated neurodevelopmental disorder. The syndrome causes infantile-onset progressive encephalopathy characterized by the neuroradiologic features of basal ganglia and periventricular white matter calcification, leucodystrophy and cerebral atrophy. Lymphocytosis and elevated levels of interferon alpha (IFN-alpha) in the cerebrospinal fluid are supplementary findings of AGS. It is frequently misdiagnosed as sequelae of congenital infection (pseudo-TORCH) and mostly recognized later. We describe three AGS cases with different clinical presentation, two male siblings with RNASEH2C mutation and a boy with TREX1 mutation. These cases highlight the importance of considering AGS in the differential diagnosis of unexplained leukoencephalopathy and developmental delay. We suggest to search for intracranial calcification, especially if there are more than one affected cases in a family. PMID:27411419

    The authors report a case of calcium oxalate arthropathy in a woman undergoing intermittent peritoneal dialysis who was not receiving pharmacologic doses of ascorbic acid. She developed acute arthritis, with calcium oxalate crystals in Heberden's and Bouchard's nodes, a phenomenon previously described in gout. Intermittent peritoneal dialysis may be less efficient than hemodialysis in clearing oxalate, and physicians should now consider calcium oxalate-associated arthritis in patients undergoing peritoneal dialysis who are not receiving large doses of ascorbic acid.

    Individuals with rheumatoid arthritis are at higher risk for infection than the general population, and surgical site infection after spinal surgery in this population can result in clinically significant complications. The goal of this study was to identify risk factors for acute surgical site infection after spinal surgery in patients with rheumatoid arthritis who were treated with nonbiologic (conventional) disease-modifying antirheumatic drugs (DMARDs) alone or with biologic DMARDs. All patients treated with biologic agents were treated with nonbiologic agents as well. The authors performed a retrospective, single-center review of 47 consecutive patients with rheumatoid arthritis who underwent spinal surgery and had follow-up of 3 months or longer. The incidence of surgical site infection was examined, and multivariate logistic regression analysis was performed to test the association of surgical site infection with putative risk factors, including the use of biologic agents, methotrexate, and prednisolone, as well as the duration of rheumatoid arthritis, the presence of diabetes, patient age, length of surgery, and number of operative levels. After spinal surgery, 14.89% (7 of 47) of patients had surgical site infection. Use of methotrexate and/or prednisolone, patient age, diabetes, duration of rheumatoid arthritis, length of surgery, number of operative levels, and use of biologic DMARDs did not significantly increase the risk of infection associated with spinal surgery. All patients who had surgical site infection had undergone spinal surgery with instrumentation. The findings show that greater attention to preventing surgical site infection may be needed in patients with rheumatoid arthritis who undergo spinal surgery with instrumentation. To the authors' knowledge, this is the first study to show that the use of biologic agents did not increase the incidence of surgical site infection after spinal surgery in patients with rheumatoid arthritis

    Infective mechanisms probably underlie a wide range of inflammatory arthropathies. There appears to be a spectrum of mechanisms ranging from the frankly septic, through low-grade infection with very small numbers of microorganisms in the joint to arthritides in which no hard evidence for an infective cause exists. In the midst of the spectrum lie 'post-infective' and 'reactive' arthritides, characterized clinically, genetically and by epidemiological links with infection. Identification of bacterial components within joint material from such patients suggested that the causes of the arthritis had been found. It is now clear that many bacteria are present in inflamed joints; establishing their significance will be of crucial importance, but not easy. PMID:12406424

    Reactive arthritis is an acute, aseptic, inflammatory arthropathy following an infectious process but removed from the site of primary infection. It is often attributed to genitourinary and enteric pathogens, such as Chlamydia, Salmonella, Shigella, Campylobacter, and Yersinia, in susceptible individuals. An uncommon and less recognized cause of this disease is preceding colonic infection with Clostridium difficile, an organism associated with pseudomembranous colitis and diarrhea in hospitalized patients and those recently exposed to antibiotics. Recognition of this association may be complicated by non-specific presentation of diarrhea, the interval between gastrointestinal and arthritic symptoms, and the wide differential in mono- and oligoarthritis. We present the case of a 61-year-old, hospitalized patient recently treated for C. difficile colitis who developed sudden, non-traumatic, right knee pain and swelling. Physical examination and radiographs disclosed joint effusion, and sterile aspiration produced cloudy fluid with predominant neutrophils and no growth on cultures. Diagnostic accuracy is enhanced by contemporaneous laboratory investigations excluding other entities such as gout and rheumatoid arthritis and other infections that typically precede reactive arthritis. Contribution of Clostridium infection to reactive arthritis is an obscure association frequently difficult to prove, but this organism is warranted inclusion in the differential of reactive arthritis.

    Tumor necrosis factor-α (TNF-α), a proinflammatory cytokine, plays a key role in the pathogenesis of many inflammatory diseases, including arthritis. Neutralization of this cytokine by anti-TNF-α antibodies has shown its efficacy in rheumatoid arthritis (RA) and is now widely used. Nevertheless, some patients currently treated with anti-TNF-α remain refractory or become nonresponder to these treatments. In this context, there is a need for new or complementary therapeutic strategies. In this study, we investigated in vitro and in vivo anti-inflammatory potentialities of an anti-TNF-α triplex-forming oligonucleotide (TFO), as judged from effects on two rat arthritis models. The inhibitory activity of this TFO on articular cells (synoviocytes and chondrocytes) was verified and compared to that of small interfering RNA (siRNA) in vitro. The use of the anti-TNF-α TFO as a preventive and local treatment in both acute and chronic arthritis models significantly reduced disease development. Furthermore, the TFO efficiently blocked synovitis and cartilage and bone destruction in the joints. The results presented here provide the first evidence that gene targeting by anti-TNF-α TFO modulates arthritis in vivo, thus providing proof-of-concept that it could be used as therapeutic tool for TNF-α-dependent inflammatory disorders.

    Interleukin-6 (IL-6) is a representative cytokine featuring pleiotropic activity and redundancy. A transient synthesis of IL-6 contributes to host defense against infectious agents and tissue injuries by inducing acute phase reactions and immunological and hematopoietic responses. However, uncontrolled persistent production of IL-6 may lead to the development of several immune-mediated diseases. Rheumatoid arthritis (RA) is a chronic disease with joint and systemic inflammation resulting from immunological abnormalities and it has been found that IL-6 plays a key role in the development of this disease. Clinical trials in various parts of the world of tocilizumab, a humanized anti-IL-6 receptor antibody, have proved its efficacy and tolerable safety either as monotherapy or in combination with disease-modifying antirheumatic drugs. As a result, it is currently used as a first-line biologic for the treatment of moderate-to-severe RA in more than 100 countries. Clarification of the mechanism(s) through which tocilizumab exerts its effect on RA and of the reason(s) why IL-6 is continuously produced in RA can be expected to lead to the best use of this agent for RA patients and aid in investigations into the pathogenesis of RA.

    On basis of clinical and immunogenetic factors most children with pauciarticular juvenile chronic arthritis can be included in one of the subtypes: type 1 and type 2 pauciarticular JCA. Type 1 occurs in young children, mainly girls, with involvement of knees, ankles or elbows. In the majority of children antinuclear antibodies can be detected. The presence of these autoantibodies is associated with chronic anterior uveitis. Type 2 or the juvenile spondylarthropathies include morbus Bechterew, the reactive arthritides and arthritis associated with psoriasis and inflammatory bowel diseases. Large joints of the lower extremities are involved, back pain is unusual at onset, but enthesitis is frequently present. There is a strong association with HLA-B27. Treatment of both subsets consists of non-steroidal anti-inflammatory drugs, application of intra-articular steroids, physio- and hydrotherapy and splinting. In children with a polyarticular course of type 1, or a prolonged course of type 2 disease modifying drugs are often needed. PMID:1957301

    Psoriatic arthritis (PA) is a chronic inflammatory condition whose symptoms generally appear after the skin symptoms. Making an early diagnosis and treatment of the disease is of vital importance because of the potential development of mutilating and deforming arthritis. Classical treatments of PA include the use of non-steroid anti-inflammatory drugs, disease-modifying antirheumatic drugs (DMARD) such as methotrexate, sulfasalazine, or gold, and finally, leflunomide. Research on the pathophysiology of psoriasis and of the PA has led to the incorporation of biological treatments, specifically anti-TNF drugs. The three treatments used most in PA are etanercept, infliximab and adalimumab. Of all these, we are going to make a systematic review of the principal studies available on etanercept for the treatment of PA. PMID:20492877

The patient had a history of one and half a year of bilateral heel pain, followed by pain in the right knee and ankle and right hip joint. He developed psoriatic lesions affecting his nails and skin. He had increased erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) contents. Human leukocyte antigen (HLA) B27 was detected but serum rheumatoid factor was not in the patient. A skin biopsy revealed psoriasis and ultrasonography demonstrated synovitis in right knee and ankle. Juvenile psoriatic arthritis was diagnosed based on his physical, laboratory and skin biopsy findings. A treatment with nonsteroidal anti-inflammatory drugs and sulfasalazine produced no effect. Leflunomide in conjunction with anti-TNF biologic agents (Etanercept) was administered, followed by symptomatic improvement 2 weeks later. PMID:17706035

    Open prospective studies and randomized controlled trials (RCT) have shown the short-term efficacy of adalimumab (ADA) in psoriatic arthritis (PsA) and psoriasis. ADA effectively treated all varied musculoskeletal manifestations characteristic of PsA, including peripheral arthritis, spinal disease, enthesitis, and dactylitis. ADA significantly inhibited structural changes on radiographs, lessened disability, and improved quality of life in patients with active PsA. One study showed the efficacy of 24-week ADA therapy on bone marrow edema and erosions, as measured by magnetic resonance imaging. The clinical and radiographic efficacy of ADA demonstrated during short-term treatment was sustained during longterm treatment. ADA was generally well tolerated and its safety profile was similar to that reported in studies of ADA in rheumatoid arthritis. Overall, ADA has a favorable risk-benefit profile in PsA. The combination of ADA and cyclosporine seems to be more effective than ADA monotherapy in patients with active PsA and inadequate response to methotrexate; however, this observation must be confirmed in RCT.

    Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder characterized by synovitis that leads to cartilage and bone erosion by invading fibrovascular tissue. Mouse models of RA recapitulate many features of the human disease. Despite the availability of medicines that are highly effective in many patient populations, autoimmune diseases (including RA) remain an area of active biomedical research, and consequently mouse models of RA are still extensively used for mechanistic studies and validation of therapeutic targets. This review aims to integrate morphologic features with model biology and cover the key characteristics of the most commonly used induced and spontaneous mouse models of RA. Induced models emphasized in this review include collagen-induced arthritis and antibody-induced arthritis. Collagen-induced arthritis is an example of an active immunization strategy, whereas antibody- induced arthritis models, such as collagen antibody-induced arthritis and K/BxN antibody transfer arthritis, represent examples of passive immunization strategies. The coverage of spontaneous models in this review is focused on the TNFΔ (ARE) mouse, in which arthritis results from overexpression of TNF-α, a master proinflammatory cytokine that drives disease in many patients.

    Immunodiagnostics play an important role in the differential diagnostics of arthritis but the test results must be interpreted with respect to the clinical context. The detection of antibodies against citrullinated proteins has significantly improved the immunodiagnostics of arthritis, whereas the importance of testing for rheumatoid factor has decreased due to the low specificity. Antibodies against carbamylated or oxidized proteins will expand the immunodiagnostics of arthritis (especially rheumatoid arthritis) in the future. In contrast, the determination of cytokine concentrations in plasma or synovial fluid plays a subordinate role in the differential diagnostics of arthritis. Indirect immunofluorescence continues to be the gold standard in the detection of antinuclear antibodies (ANA) and in the case of positive results further testing for antigen specificity should be carried out. The presence of ANA is not necessarily associated with autoimmune diseases. An example of a non-pathogenic ANA is anti-DFS70 antibodies. PMID:27142378

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease characterized by extensive synovitis resulting in erosions of articular cartilage and marginal bone with joint destruction. The lack of immunological tolerance in RA represents the first step toward the development of autoimmunity. Susceptible individuals, under the influence of environmental factors, such as tobacco smoke, and silica exposure, develop autoimmune phenomena that result in the presence of autoantibodies. HLA and non-HLA haplotypes play a major role in determining the development of specific autoantibodies differentiating anti-citrullinated antibodies (ACPA)-positive and negative RA patients. Rheumatoid factor (RF) and ACPA are the serological markers for RA, and during the preclinical immunological phase, autoantibody titers increase with a progressive spread of ACPA antigens repertoire. The presence of ACPA represents an independent risk factor for developing RA in patients with undifferentiated arthritis or arthralgia. Moreover, anti-CarP antibodies have been identified in patients with RA as well as in individuals before the onset of clinical symptoms of RA. Several autoantibodies mainly targeting post-translational modified proteins have been investigated as possible biomarkers to improve the early diagnosis, prognosis and response to therapy in RA patients. Psoriatic arthritis (PsA) is distinguished from RA by infrequent positivity for RF and ACPA, together with other distinctive clinical features. Actually, specific autoantibodies have not been described. Recently, anti-CarP antibodies have been reported in sera from PsA patients with active disease. Further investigations on autoantibodies showing high specificity and sensibility as well as relevant correlation with disease severity, progression, and response to therapy are awaited in inflammatory arthritides.

    Rheumatoid arthritis (RA) is chronic joint disease which if untreated leads to permanent structural damage and disability. Early diagnosis and therapy are the main requests for good clinical practice. Early diagnosis tools include specific clinical assesment, serological, immunogenetic and radiological evaluation. Disease activity score is cornerstone in clinical assesment, rheumatoid factor and anti-cyclic citrullinated peptide antibodies (anti-CCP) are very specific serological parameters. The shared epitope containing HLA-DRB1* alleles represent the most significant genetic risk for RA. Magnetic resonance and ultrasound imaging are very sensitive methods in early phase of disease.

    Background Sex medicine studies have shown that there are sex differences with regard to disease characteristics in immune-mediated inflammatory diseases, including psoriasis, in immune response and susceptibility to viral infections. We performed a post hoc analysis of the Observational Study of infectious events in psoriasis complicated by active psoriatic arthritis (SYNERGY) study in patients with psoriatic arthritis (PsA) treated with immunosuppressive regimens including cyclosporine, in order to evaluate potential between-sex differences in severity of disease and prevalence of viral infections. Methods SYNERGY was an observational study conducted in 24 Italian dermatology clinics, which included 238 consecutively enrolled patients with PsA, under treatment with immunosuppressant regimens including cyclosporin A. In this post hoc analysis, patients’ demographical data and clinical characteristics of psoriasis, severity and activity of PsA, prevalence of seropositivity for at least one viral infection, and treatments administered for PsA and infections were compared between sexes. Results A total of 225 patients were evaluated in this post hoc analysis, and 121 (54%) were males. Demographic characteristics and concomitant diseases were comparable between sexes. Statistically significant sex differences were observed at baseline in Psoriasis Area and Severity Index score (higher in males), mean number of painful joints, Bath Ankylosing Spondylitis Disease Activity Index, and the global activity of disease assessed by patients (all higher in females). The percentage of patients with at least one seropositivity detected at baseline, indicative of concomitant or former viral infection, was significantly higher among women than among men. No between-sex differences were detected in other measures, at other time points, and in treatments. Patients developed no hepatitis B virus or hepatitis C virus reactivation during cyclosporine treatment. Conclusion Our post hoc

    The role of endogenous glucocorticoids (GCs) in rheumatoid arthritis remains unclear. Herein, we examined the role of osteoblastic GC signaling in collagen antibody-induced arthritis. Intracellular GC signaling was abrogated exclusively in mature osteoblasts via transgenic (tg) expression of 11ß-hydroxysteroid dehydrogenase type 2. Arthritis was induced in 8-week-old male tg mice and their wild-type (WT) littermates. Paw swelling was scored daily from induction to end point (day 14). Inflammation, cartilage degradation, and local bone erosion were assessed at the wrist, knee, and ankle joints. Systemic skeletal changes were determined by microcomputed tomography and histomorphometrical analysis of the tibiae. Both tg and WT mice developed acute arthritis in response to the administration of collagen antibodies. However, compared with WT mice, both clinical and histological indexes of joint inflammation were significantly mitigated in animals with disrupted osteoblastic GC signaling. In WT mice, arthritis was associated with increased bone resorption, decreased bone formation, and significant bone loss. In contrast, bone turnover and bone mass remained unchanged in tg arthritic mice. Disruption of GC signaling in osteoblasts significantly reduces joint inflammation and prevents structural bone and cartilage damage in collagen antibody-induced arthritis. These data corroborate the concept that osteoblasts modulate the inflammatory response in immune-mediated arthritis via a GC-dependent pathway. PMID:26988651

    Granulocyte-macrophage colony-stimulating factor (GM-CSF) is well-known as a haemopoietic growth factor. However, it is also essential in regulating functions of mature myeloid cells such as macrophages. Preclinical studies and observations of flares of arthritis in patients following GM-CSF treatment supported its important contribution to the pathogenesis of rheumatoid arthritis (RA). As the most advanced compound, mavrilimumab, a monoclonal antibody against GM-CSF receptor, has already completed phase II trials with a long term of follow-up period of 74 weeks. During this exposure period, an acceptable sustained safety and tolerability profile has been observed addressing the concerns of development of cytopenias or pulmonary alveolar proteinosis. Of note, a rapid and sustained efficacy and normalisation of acute phase reactants were consistently shown in studies both targeting GM-CSF and its receptor. Its tumour necrosis factor (TNF) independent mode of action with concurrent blockade of GM-CSF as well as IL-17 signalling reported from preclinical studies supports the assumption that it can be a useful biologic and an alternative agent in TNF inhibitor resistant patients with RA. Therefore, subsequent studies are warranted to investigate the safety and efficacy of GM-CSF blocking agents in different subgroups of RA. PMID:27586802

Search terms included: “reactive arthritis”, “spondyloarthropathy”, “Reiter’s syndrome”, “gastroenteritis”, “diarrhea”, “epidemiology”, “incidence”, “prevalence”, and “Campylobacter”. Results The literature available to date suggests that the incidence of Campylobacter reactive arthritis may occur in 1 to 5% of those infected. The annual incidence of ReA after Campylobacter or Shigella may be 4.3 and 1.3 respectively per 100,000. The duration of acute ReA varies considerably between reports, and the incidence and impact of chronic reactive arthritis from Campylobacter infection is virtually unknown. Conclusions Campylobacter associated ReA incidence and prevalence varies widely from reviews such as: case ascertainment differences, exposure differences, lack of diagnostic criteria for ReA and perhaps genetics and ages of exposed individuals. At the population level it may not be associated with HLA-B27 and inflammatory back involvement is uncommon. Follow up for long-term sequelae is largely unknown. Five percent of Campylobacter ReA may be chronic or relapsing (with respect to musculoskeletal symptoms). PMID:17360026

  17. Etodolac: analgesic effects in musculoskeletal and postoperative pain.

    PubMed

    Pena, M

    1990-01-01

    Numerous clinical trials have shown etodolac to be an effective analgesic. The purpose of the present report is to review results of 14 studies that demonstrate the effectiveness of etodolac in a variety of painful conditions. Presented are the results of four postsurgical pain studies, one study of acute gouty arthritis and nine studies of acute musculoskeletal disorders: acute low back pain, acute painful shoulder, tendinitis and bursitis, and acute sports injuries. A single oral dose of etodolac (25, 50, 100, 200, or 400 mg) was compared with aspirin (650 mg) or a combination of acetaminophen (600 mg) plus codeine (60 mg) for the relief of pain up to 12 h following oral, urogenital or orthopedic surgery. In multiple dose studies of acute gouty arthritis and musculoskeletal conditions, etodolac 200 or 300 mg twice a day (b.i.d.) or 200 mg three times a day (t.i.d.) was compared with naproxen 500 mg b.i.d. or t.i.d., diclofenac 50 mg b.i.d. or t.i.d., and piroxicam 20 or 40 mg once a day (o.d.) administered over 5 to 14 days. The efficacy of etodolac was at least equal and in some ways superior to aspirin and acetaminophen plus codeine in the relief of postsurgical pain. In studies of acute gouty arthritis, significant improvement from baseline were seen for all efficacy parameters evaluated for both the etodolac- and naproxen-treated patients. All the present studies of musculoskeletal conditions have shown etodolac to be effective and comparable in analgesic efficacy to naproxen, diclofenac or piroxicam. In summary, etodolac therapy for pain following surgery, in acute gouty arthritis and in acute musculoskeletal conditions resulted in analgesia comparable to that provided by several well-established analgesic or anti-inflammatory agents.

    Chronic neutrophilic leukemia (CNL) is a rare entity amongst myeloproliferative neoplasms (MPNs). The classical presentation of CNL is with splenomegaly, mature neutrophilic leucocytosis and hyperuricemia. We herein report a case who presented with symptoms of acute gouty arthritis. Physical examination showed typical red, tender tophi in the right hand, right foot and both pinnae suggesting an acute episode of gout. During evaluation, moderate splenomegaly, mature neutrophilia, hyperuricemia and sub-nephrotic range range proteinuria were noted. Bone marrow examination and kidney biopsy was done. Final diagnosis of CNL with acute gouty arthritis and chronic renal thrombotic microangiopathy (TMA) was made. Although hyperuricemia is a common finding in MPNs but presentation of our case with symptoms of acute tophi and chronic TMA is atypical. PMID:27408367

    2015-06-01

    Gout is an inflammatory, metabolically conditioned crystal-induced disease. Prevalence of gout is on the increase. In clinical practice it is frequently wrongly diagnosed and the therapy of acute attacks in particular is not adequate. The first part of the publication discusses diagnostic possibilities of gouty arthritis. First of all the advantage of the analysis of synovial exudate and of direct evidence of crystals in the polarization microscope is emphasized. If the material for crystallographic analysis is not available, it is necessary to use a combination of clinical criteria as specified e.g. in the recommendations of the European League Against Rheumatism (EULAR). The second part focuses on the therapy of gout which is divided into the periods of asymptomatic hyperuricemia, acute gouty attack, intercritical and chronic tophaceous gout. Asymptomatic hyperuricemia is only treated when uricemia greater than 540 µmol/l occur repeatedly, or when other risk factors and comorbidities are present. In the treatment of acute gouty attack its early start is more important than the choice of a preparation. Alternatives are NSA, colchicine or glucocorticoids. A newly regist-ered medicine for the treatment of refractory acute inflammation is the IL-1 inhibitor canakinumab. The treatment of hyperuricemia involves regimen and diet measures, abstinence and hypouricemic therapy. Available are the xanthine oxidase inhibitors, allopurinol and febuxostat; the latter is better suited for patients with moderate renal insufficiency. A new medicine for the treatment of severe refractory tophaceous gout is pegloticase.Key words: gouty arthritis - colchicine - nonsteroidal antirheumatic drugs. PMID:26258966

    Juvenile idiopathic arthritis is the most common inflammatory rheumatic disease of childhood and represents a series of chronic inflammatory arthritides of unknown cause. Involvement of the temporomandibular joint has been reported in up to 87% of children with juvenile idiopathic arthritis when based on magnetic tomography imaging; it can be asymptomatic and may lead to severe long term complications. In this review a summary of the contemporary literature of imaging of the temporomandibular joint in children with juvenile idiopathic arthritis will be provided, including ultrasound which is a valuable method for guided joint injections, but does not necessarily allow detection of acute inflammation, cone beam computed tomography, which has emerged as a feasible and accurate low-dose alternative as compared to conventional computed tomography to detect destructive change, and magnetic resonance imaging which is considered the method of choice for assessing acute, inflammatory change, although the lack of normative standards remains a challenge in children.

    Rheumatoid arthritis (RA) is a chronic inflammatory disease caused by both genetic and environmental factors. Smoking has been implicated as one of the most important extrinsic risk factors for its development and severity. Recent developments have shed light on the pathophysiology of RA in smokers, including oxidative stress, inflammation, autoantibody formation and epigenetic changes. The association of smoking and the development of RA have been demonstrated through epidemiologic studies, as well as through in vivo and animal models of RA. With increased use of biological agents in addition to standard disease-modifying antirheumatic drugs (DMARDs), there has been interest in how smoking affects drug response in RA treatment. Recent evidence suggests the response and drug survival in people treated with anti-tumour necrosis factor (anti-TNF) therapy is poorer in heavy smokers, and possible immunological mechanisms for this effect are presented in the current paper.

    Rheumatoid arthritis (RA) is a chronic and painful clinical condition that leads to progressive joint damage, disability, deterioration in quality of life, and shortened life expectancy. Even mild inflammation may result in irreversible damage and permanent disability. The clinical course according to symptoms may be either intermittent or progressive in patients with RA. In most patients, the clinical course is progressive, and structural damage develops in the first 2 years. The aim of RA management is to achieve pain relief and prevent joint damage and functional loss. Physiotherapy and rehabilitation applications significantly augment medical therapy by improving the management of RA and reducing handicaps in daily living for patients with RA. In this review, the application of physiotherapy modalities is examined, including the use of cold/heat applications, electrical stimulation, and hydrotherapy. Rehabilitation treatment techniques for patients with RA such as joint protection strategies, massage, exercise, and patient education are also presented. PMID:15266230

  5. Leflunomide for rheumatoid arthritis.

    PubMed

    2000-07-01

    Disease-modifying antirheumatic drugs (DMARDs) are given to patients with rheumatoid arthritis (RA) to prevent synovitis, slow destruction of articular cartilage and bone, preserve function and control systemic manifestations of the disease. Recognition that irreversible joint damage often occurs early in RA has led to much prompter use of DMARDs, with sulfasalazine or methotrexate commonly considered the treatment of first choice. Leflunomide (Arava-Aventis) is a new DMARD, licensed for the treatment of adults with active RA. The manufacturer claims that leflunomide has "comparable efficacy to methotrexate and sulphasalazine", with a "faster onset of action", and an "acceptable tolerability profile". Here, we consider the place of leflunomide in the management of patients with RA. PMID:11027115

    Juvenile Idiopathic Arthritis (JIA) is the most chronic musculoskeletal disease of pediatric population. The chronic course of disease has a great impact on oral health. Temporomandibular joint is involved in JIA causing limited mouth opening with progressive open bite, retrognathia, microgenia and bird like appearance. Joints of upper and lower extremities are also involved. Effect on upper limb function leads to difficulty with fine motor movements required for brushing and flossing. This increases incidence of caries and periodontal disease in children. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, prognosis has improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage as multidisciplinary management is essential. PMID:24808703

    Rheumatoid arthritis (RA) is associated with excess mortality. Especially, malignancy is a major cause of mortality. According to previous reports, the overall incidence of malignancies in RA patients has been reported to be comparable or slightly higher than that in general population. The increased incidence of malignant lymphoma and lung cancer has been reported to be consistent in most studies. The use of some csDMARD was also reported as risk factors for malignancy. Recently, MTX associated lymphoproliferative disorder(MTX-LPD) is one of the important complications in RA treatment. We revealed the mean MTX dose was demonstrated to be an independent risk factor regarding MTX-LPD onset in RA patients. This data suggest that the treatment with higher MTX dose promotes LPD onset in Japanese RA patients. PMID:27311195

    We assessed the effect of a novel and selective phosphodiesterase 4 (PDE4) inhibitor, ciclamilast, on chronic inflammation in adjuvant-induced arthritis (AIA), a rat model of rheumatoid arthritis (RA), and acute inflammation in the rat and mouse model of carrageenan-induced paw edema and peritonitis. Our results showed that daily oral administration of ciclamilast at 1, 3, and 10 mg/kg dose-dependently inhibited the increase in hind paw volume of rats with AIA. The inhibition of paw edema was associated with inhibition of both the production of cytokines such as TNF-α, IL-1β, and IL-6 and cell infiltration assessed in subcutaneous paw tissue. Moreover, there was significantly less tissue destruction in the ciclamilast-treated rats compared to the vehicle-treated rats, as assessed by radiographic analysis and histopathological evaluation. In the two acute inflammation models, ciclamilast inhibited carrageenan-induced paw edema in rats and inflammatory cell migration into the peritoneal cavity in mice in a dose-dependent manner. These results not only suggest that ciclamilast, as a disease-modifying antirheumatic drug (DMARD), can attenuate RA but also provide proof of principle that a PDE4 inhibitor may be useful for the treatment of arthritis.

    Aicardi-Goutières syndrome (AGS) is an encephalopathy of early childhood which is most commonly inherited as an autosomal recessive trait. The disorder demonstrates significant genetic heterogeneity with causative mutations in five genes identified to date. Although most patients with AGS experience a severe neonatal or infantile presentation, poor neurodevelopmental outcome and reduced survival, clinical variability in the onset and severity of the condition is being increasingly recognized. A later presentation with a more variable effect on development, morbidity and mortality has been particularly observed in association with mutations in SAMHD1 and RNASEH2B. In contrast, the recurrent c.205C > T (p.R69W) RNASEH2C Asian founder mutation has previously only been identified in children with a severe AGS phenotype. Here, to our knowledge, we present the first report of marked phenotypic variability in siblings both harboring this founder mutation in the homozygous state. In this family, one female child had a severe AGS phenotype with an onset in infancy and profound developmental delay, whilst an older sister was of completely normal intellect with a normal head circumference and was only diagnosed because of the presence of chilblains and a mild hemiplegia. An appreciation of intrafamilial phenotypic expression is important in the counseling of families considering prenatal diagnosis, and may also be relevant to the assessment of efficacy in future clinical trials. In addition, marked phenotypic variation raises the possibility that more mildly affected patients are not currently identified. PMID:23322642

    The neuroinflammatory autoimmune disease Aicardi-Goutières syndrome (AGS) develops from mutations in genes encoding several nucleotide-processing proteins, including RNase H2. Defective RNase H2 may induce accumulation of self-nucleic acid species that trigger chronic type I interferon and inflammatory responses, leading to AGS pathology. We created a knock-in mouse model with an RNase H2 AGS mutation in a highly conserved residue of the catalytic subunit, Rnaseh2a(G37S/G37S) (G37S), to understand disease pathology. G37S homozygotes are perinatal lethal, in contrast to the early embryonic lethality previously reported for Rnaseh2b- or Rnaseh2c-null mice. Importantly, we found that the G37S mutation led to increased expression of interferon-stimulated genes dependent on the cGAS-STING signaling pathway. Ablation of STING in the G37S mice results in partial rescue of the perinatal lethality, with viable mice exhibiting white spotting on their ventral surface. We believe that the G37S knock-in mouse provides an excellent animal model for studying RNASEH2-associated autoimmune diseases. PMID:26880576

    Ribonuclease H2 plays an essential role for genome stability as it removes ribonucleotides misincorporated into genomic DNA by replicative polymerases and resolves RNA/DNA hybrids. Biallelic mutations in the genes encoding the three RNase H2 subunits cause Aicardi-Goutières syndrome (AGS), an early-onset inflammatory encephalopathy that phenotypically overlaps with the autoimmune disorder systemic lupus erythematosus. Here we studied the intracellular dynamics of RNase H2 in living cells during DNA replication and in response to DNA damage using confocal time-lapse imaging and fluorescence cross-correlation spectroscopy. We demonstrate that the RNase H2 complex is assembled in the cytosol and imported into the nucleus in an RNase H2B-dependent manner. RNase H2 is not only recruited to DNA replication foci, but also to sites of PCNA-dependent DNA repair. By fluorescence recovery after photobleaching, we demonstrate a high mobility and fast exchange of RNase H2 at sites of DNA repair and replication. We provide evidence that recruitment of RNase H2 is not only PCNA-dependent, mediated by an interaction of the B subunit with PCNA, but also PCNA-independent mediated via the catalytic domain of the A subunit. We found that AGS-associated mutations alter complex formation, recruitment efficiency and exchange kinetics at sites of DNA replication and repair suggesting that impaired ribonucleotide removal contributes to AGS pathogenesis.

    Reactive arthritis has been classically defined as an aseptic arthritis induced by a bacterial infection in another organ. If the classical form of reactive arthritis is in fact a spondyloarthritis triggered by a urogenital or intestinal bacterial infection, it is not necessarily sterile, and in some cases it may be worthwhile to treat a chronic infection with long-term antibiotherapy. In a broader definition, the concept of reactive arthritis is widened to other post-infectious rheumatism, such as post-streptococcal arthritis or post-viral arthritis. PMID:27089639

He did not respond to oral doxycycline and cephalexine for presumed Lyme's disease. Further investigation confirmed strongly positive streptococcal serology. There was absence of clinical or echocardiography evidence of heart involvement and immunological screening for inflammatory arthritis was negative. In the absence of other major Jones criteria for acute rheumatic fever, besides polyarthritis and the serological evidence of a recent streptococcal infection, a diagnosis of post-streptococcal reactive arthritis (PSRA) was also made. He responded well to penicillin therapy and has been started on oral penicillin prophylaxis as per available guidance. As streptococcal infections in the adult population are increasingly reported, it is a timely opportunity to revisit PSRA, and develop comprehensive treatment and antibiotic prophylaxis guidelines.

    1992-12-01

    Corticosteroids were used to treat two children with presumed idiopathic thrombocytopenic purpura and one with juvenile rheumatoid arthritis without examination of the bone marrow. Of the two with presumed idiopathic thrombocytopenic purpura, one had Fanconi's anaemia and the other may have had aplastic anaemia. The third child had acute lymphoblastic leukaemia. The diagnosis of Fanconi's anaemia was delayed. A diagnostic and therapeutic dilemma was caused in the second case. In the third, delayed diagnosis and, perhaps, compromised outlook resulted. These three cases re-emphasize the well aired caveats about the diagnosis of idiopathic thrombocytopenic purpura and juvenile rheumatoid arthritis and provide further support for the arguments of those who believe that if corticosteroids are to be used to treat such children, their bone marrow should be examined first.

    Juvenile idiopathic arthritis (JIA) is a group of diseases defined by the presence of arthritis of more than 6weeks duration in patients aged less than 16years and with unknown etiology. The international classification based on clinical and biological criteria define each type of JIA: systemic, oligoarticular, polyarticular with and without rheumatoid factor, enthesitis-related arthritis, and psoriatic arthritis. However, some discussions persist concerning systemic-onset juvenile idiopathic arthritis, whose clinical symptoms and pathogenic mechanisms are quite similar to those observed in autoinflammatory diseases, arthritis with antinuclear factors (poly- and oligoarticular) that could be considered as a homogenous group, and a family history of psoriasis that frequently led to unclassified arthritis. Better knowledge of the pathogenic mechanisms should improve the initial clinical classification with more homogeneous groups of patients and reduce the number of unclassified cases of arthritis.

    Only six of the many alphavirus known to affect humans can cause articular manifestations. They are the Ross River and Barmah Forest viruses from the South Pacific, the Chikungunya, O'Nyong Nyong and Sindbis viruses from tropical Africa, and the Mayaro virus from South America. In most cases, articular manifestations involve arthralgia or transient arthritis and are usually minor. However in some cases especially involving Ross River virus acute polyarthritis may be the most prominent clinical feature and even develop before fever. Although these joint symptoms may be severe and persist for weeks or months in a subacute mode with slightly inflammatory episodes that can be relieved using analgesics, they never cause permanent damage. Differential diagnosis of alphavirsus-related polyarthritis is simple to diagnosis especially in epidemic outbreaks as is frequently the case for Ross River virus epidemics in Australia. Imported cases should be suspected in patients presenting acute or subacute polyarthritis after a recent stay of any length of time in a tropical country and can be confirmed by ordering serology from a specialized reference laboratory.

  10. Rheumatoid arthritis and pregnancy.

    Klipple, G L; Cecere, F A

    1989-05-01

    The activity of RA is significantly altered by pregnancy with approximately 70 per cent of patients experiencing substantial improvement in symptoms, signs and sometimes extra-articular manifestations. This lessening of disease activity occurs in association with an almost complete cessation of medications. However, whether partial or complete this remission is short-lived with more than 90 per cent of women who improved relapsing by 6 to 8 months postpartum. Further, in approximately 30 per cent of RA patients the course remains unchanged or worsens during gestation and indeed the first symptoms of RA may develop during pregnancy or shortly thereafter. Conversely active rheumatoid arthritis seems to little influence the maternal course or fetal outcome of pregnancy. The multiple and complex immunologic alterations of the pregnant state are designed to ensure survival of the fetal allograft in a foreign host. A number of these alterations particularly involving modulation of cell-mediated immunity, immunoglobulin composition, immune complex generation, or the inflammatory response have the potential to interfere with the pathophysiology of RA. In short, although the specific mechanism remains an enigma, the reason for the amelioration of RA during pregnancy is probably an incidental and fortuitous reaction to one or more of these immunomodulatory factors.

    Patients with rheumatoid arthritis (RA) suffer an increased burden of infectious disease-related morbidity and mortality and have twice the risk of acquiring a severe infection compared to the general population. This increased risk is not only a result of the autoimmune disease but is also attributed to the immunosuppressive therapies that are commonly used in this patient population. Given the increase in infection-related risks in RA, there is great interest in mitigating such risk. A number of vaccines are available to the rheumatologist, with a handful that are of importance for RA patients in the United States. The goal of this paper is to highlight the most recent literature on the key vaccines and the specific considerations for the rheumatologist and their RA patients, with a particular focus on influenza, pneumococcal, and herpes zoster vaccines. It is important for rheumatologist to understand and be aware of which vaccines are live and what potential contraindications exist for giving vaccines to RA patients. PMID:24925587

    The frequency and histopathological characteristics of systemic vasculitis were studied in the autopsy material of 161 patients with rheumatoid arthritis. Systemic vasculitis was observed in 36 case (22.4%). In percentage of all cases with systemic vasculitis, the most frequently involved organs were the heart (66.7%), skeletal muscles (54.8%), and peripheral nerves (52%). The skin was involved only in about one third of 36 cases (36%). In most cases the arterioles and the small arteries were affected by vasculitis. Three types of vasculitis (non specific, fibrinoid necrotic, granulomatous) could be observed simultaneously in different vessels or combined in the same vessel. Different stages of inflammation could be found simultaneously, reflecting the relapsing nature of vasculitis. The frequency, the severity, and the recurrence of vasculitis are different aspects of the same phenomenon running usually parallel to each other in different organs and on different vessels. Vasculitis lead to local ischaemia and regressive changes depend on the number and size of the involved vessels. Systemic vasculitis led to death in 19 of 36 cases. Vasculitis was detected clinically in 7 of 36 cases. Exitus lethalis depend on the localization of the involved vessels. Vasculitis in the heart and brain are more life threatening, than that of localized to the skin. PMID:8757068

    Background and objective Since the original description of psoriatic arthritis (PsA) subgroups by Moll and Wright, there has been some discrepancy in the precise prevalence of the different subgroups and in particular the proportion of patients with polyarthritis. The higher prevalence of the polyarthritis subgroup may be due to the inclusion of patients with seronegative rheumatoid arthritis with coincidental psoriasis. The classification of psoriatic arthritis (CASPAR) study database provided an opportunity to examine this question. Methods The CASPAR study collected clinical, radiological and laboratory data on 588 patients with physician‐diagnosed PsA and 525 controls with other inflammatory arthritis, 70% of whom had rheumatoid arthritis. Patients with PsA were divided into two groups: polyarthritis and non‐polyarthritis (which included the Moll and Wright subgroups of spinal disease, distal interphalangeal predominant and arthritis mutilans) and were compared with patients with rheumatoid arthritis. Comparisons were made between all three groups and, if a significant difference occurred, between the two groups with PsA. Results The three groups differed significantly with regard to all clinical and laboratory variables except duration of disease. Significant differences were also found between the two groups of PsA in terms of age, sex, total number of involved joints, disability score and symmetry. However, no differences were found between the groups of patients with PsA in terms of seropositivity for rheumatoid factor and antibodies to cyclic citrullinated peptide, enthesitis, and spinal pain and stiffness. Further, dactylitis was commonly seen in patients with PsA (57% in the polyarticular group and 45% in non‐polyarticular group), and uncommonly found in patients with rheumatoid arthritis (5%). With the exception of entheseal changes, syndesmophytes and osteolysis, typical radiological features of PsA could not be used to distinguish between the Ps

    Ten episodes of severe pyogenic infection occurring in nine patients with rheumatoid arthritis are reported. There was a wide range of presenting features including pyoarthrosis in 7 episodes. Three cases presented with meningitis, bacterial endocarditis and probable multiple abscesses respectively. Infection was caused by Staphylococcus aureus in 7 episodes and by Staphylococcus epidermidis, Streptococcus pneumoniae and beta-haemolytic Streptococcus in each of one episode. Three infective episodes were fatal. Pyogenic, especially staphylococcal, infection should be considered in patients with rheumatoid arthritis with unexplained illness with or without sudden deterioration in joint symptoms. It is important to recognize and treat infection rapidly. Images Figure 1 Figure 2 PMID:3671222

    Childhood arthritis has now been reclassified into a single internationally recognized entity of juvenile idiopathic arthritis (JIA). Radiology provides an important role in the management of JIA, in helping in the differential diagnosis, monitoring disease progression and detecting complications. Traditionally, plain radiographs have been the imaging investigation of choice but magnetic resonance imaging (MRI) and ultrasound are now providing a more effective and safer alternative. The appropriate use of sequences in MR imaging is important in the early detection of joint abnormalities in JIA. PMID:11798203

    De La Hoz Polo, M; Navallas, M

    2014-01-01

    The term "juvenile idiopathic arthritis" (JIA) encompasses a group of arthritis of unknown cause with onset before the age of 16 years that last for at least 6 weeks. The prevalence of temporomandibular joint involvement in published series ranges from 17% to 87%. Temporomandibular joint involvement is difficult to detect clinically, so imaging plays a key role in diagnosis and monitoring treatment. MRI is the technique of choice for the study of arthritis of the temporomandibular joint because it is the most sensitive technique for detecting acute synovitis and bone edema. Power Doppler ultrasonography can also detect active synovitis by showing the hypervascularization of the inflamed synovial membrane, but it cannot identify bone edema. This article describes the MRI technique for evaluating the temporomandibular joint in patients with juvenile idiopathic arthritis, defines the parameters to look for, and illustrates the main findings.

    Reactive arthritis is a rare complication of Clostridium difficile enterocolitis, especially in children. We review the 6 pediatric cases published in the English and non-English literature and discuss their clinical presentation, outcome, treatment, and pathophysiology. We also report the seventh case of Clostridium difficile reactive arthritis in a 6-year-old boy who was treated with amoxicillin-clavulanate for 10 days because of an upper respiratory infection. After the antibiotic course, the child developed at the same time diarrhea with positive stool culture for Clostridium difficile and an asymmetric polyarthritis. Nonsteroidal anti-inflammatory drugs and metronidazole completely resolved the pain, joint swelling, and diarrhea. After twelve months of follow-up there has been no recurrence. This report confirms the self-limiting course of Clostridium difficile reactive arthritis. Clostridium difficile testing in children with gastrointestinal symptoms and acute onset of joint pain should be always considered. PMID:27190666

    Streptococcal toxic shock syndrome is a potentially lethal condition with an increasing incidence over the last 30 years. We present the case of a 55-year-old patient with signs and symptoms of streptococcal toxic shock syndrome. This patient's presentation was unique in that it was followed by an accumulation of fluid at her breast implant in addition to a polyarticular reactive arthritis. We propose that the patient's reactive arthritis is consistent with the diagnosis of post-streptococcal reactive arthritis, a variant of acute rheumatic fever, which similarly to its variant is immunologically driven. We hypothesize that the fluid collection around the patient's breast implant was triggered by her infection and was also immunologically mediated. PMID:21325958

    Acute sarcoid arthritis may be present in isolation or as part of Löfgren's syndrome. Its true incidence is unclear since the diagnosis may be difficult when patients present with articular symptoms alone. The diagnosis of sarcoid arthritis is based upon suggestive clinical, imaging, synovial fluid findings, and in some cases upon synovial biopsy. The finding of sterile noncaseating granulomatous inflammation on biopsy is supportive, but it is not pathognomic of sarcoidosis. On the other hand, sarcoidosis has been associated with autoimmune diseases, especially with autoimmune thyroid disease. We believe that it might be of interest to evaluate thyroid function testing in patients with clinical features consistent with sarcoid arthritis, and the diagnosis of sarcoidosis should be considered in patients who present with symmetrical arthritis and thyroid autoimmune disease. We describe herein a patient with subclinical autoimmune hypothyroidism and an acute symmetrical oligoarthritis, with a clinical presentation and laboratory data consistent with acute sarcoid arthritis (Ref. 14).

    Spondyloarthritis (SpA) represents a group of inflammatory rheumatic diseases that cluster within families and possess overlapping clinical features. The pathogenesis of SpA encompasses a complex array of genetic, immunological and environmental factors. In this article, we will briefly review the genetics of PsA, and then focus on the genes that may be potentially linked either directly or indirectly to the immunopathology of the Th-17 pathway. The most consistent and dominant genetic effect of PsV and PsA is located on chromosome 6p21.3 within the major histocompatibility complex (MHC) region, which accounts for approximately one-third of the genetic contribution of PsV and PsA. To date, 36 genes have reached genome-wide significance, accounting for approximately 22% of psoriasis (PsV) heritability. Prominent genes identified via GWAS include HLA-Cw6, IL12B, IL23R, IL23A, TNIP1, TNFAIP3, LCE3B-LCE3C, TRAF3IP2, NFkBIA, FBXL19, TYK2, IFIH1, REL, and ERAP1. Genes identified in psoriatic arthritis (PsA) has largely echoed those in PsV and include HLA-B/C, HLA-B, IL-12B, IL-23R, TNIP1, TRAF3IP2, FBXL19, and REL. The lack of identified genetic susceptibility loci is largely attributed to the much smaller number of PsA patients and the greater clinical heterogeneity of PsA. Searching for different types of genetic variants such as small CNVs and/or insertions/deletions has also led to the identification of several genes with a function relative to PsV in particular including DEFB4, LCE3C_LCE3B, and IL-22 gene (exon 1). The candidate genes identified in PsV/PsA have highlighted pathways of critical importance to psoriatic disease including distinct signaling pathways comprised of barrier integrity, innate immune response and adaptive immune response, mediated primarily by Th-17 and Th-1 signalling. While GWAS studies have yielded great insights into the genes that contribute to the pathogenesis of PsV and PsA, replication in large cohorts, fine-mapping and resequencing

    Our understanding of psoriatic arthritis has evolved as new knowledge of the disease has emerged. However, the exact prevalence of psoriatic arthritis is unknown, and its pathogenesis has not been fully elucidated. Genetic, environmental, and immunologic factors have all been implicated in disease development. Early diagnosis and treatment have become primary objectives in clinical rheumatology. Psoriatic arthritis not only causes functional impairment, but also increases mortality risk of patients. The advent of new therapeutic agents capable of arresting the progression of joint damage is expected. However, early psoriatic arthritis assessment remains limited. The objectives of this article are to outline the epidemiology, diagnosis, and treatment of psoriatic arthritis and to suggest a paradigm for identifying early psoriatic arthritis patients.

    A 35-year old woman presented with pustulosis palmaris et plantaris evolving in acute episodes parallel to those of a rheumatic disease consisting of bilateral sacro-iliac arthritis, manubriosternal fusion and sterno-clavicular arthritis. Her brother had spondylitis compatible with the diagnosis of pustular osteo-arthritis though without pustulosis. He presented with bilateral sacro-iliac arthritis, manubriosternal fusion, sterno-clavicular arthritis and an ossified fragment detached from the antero-inferior angle of C6. The two patients had the same HLA phenotype: A1, A9, B5, B41, CW4, DR2, DR4, absence of B27. In a specimen from the sacro-iliac joint the authors found active bone remodelling and inflammatory osteitis with fibrosis and infiltrates rich in mononucleate cells. An electron microscopic study--to the authors' knowledge, the first to be performed in such cases--demonstrated intracytoplasmic filamentous inclusions in two macrophages of the synovial fringe. Only one other case of the familial form has been published so far. Like the rheumatism of acne conglobata, the spondylitis of pustulosis palmaris et plantaris is one of the causes of sterno-costo-clavicular hyperostosis. PMID:3563168

    Psoriatic arthritis (PsA) is a chronic.immune-mediated disease that is observed in 8-30% of psoriatic patients. It has been recently established that PsA and psoriasis are closely associated with the high prevalence of metabolic syndrome, hypertension; abdominal obesity, and a risk for cardiovascular diseases (CVD), including fatal myocardial infarction (Ml) and acute cerebrovascular accidents, which shortens lifespan in the patients compared to the general population. The authors state their belief that the synergic effect of traditional risk factors (RFs) for CYD and systemic inflammation underlie the development of atherosclerosis in PsA. It is pointed out that the risk of CYD may be reduced not only provided that the traditional RFs for CVD are monitored, but also systemic inflammation is validly suppressed. The cardioprotective abilities of methotrexate and tumor necrosis factor-a (TNF-a) inhibitors are considered; the data of investigations showing that the treatment of PsA patients with TNF-a inhibitors results in a reduction in carotid artery intima-media thickness are given. lt is noted that there is a need for the early monitoring of traditional RFs for CVD in patients with PsA and for the elaboration of interdisciplinary national guidelines.
