Bilateral Otic Manifestation of Pseudogout: A Unique Case Report of Conductive Hearing Loss.

Pseudogout is characterized by the deposition of calcium pyrophosphate dihydrate crystals (CPPD), primarily affecting large joints. Extra-articular manifestations, particularly in the head and neck region, are exceedingly rare. We report a unique case of bilateral isolated pseudogout of the middle ear manifesting with progressive conductive hearing loss as the first and only symptom of pseudogout. Otoscopy and CT scan often yield a differential diagnosis that includes tumors or cholesteatoma, necessitating surgery with histopathological examination. The definitive diagnosis is confirmed upon identification of calcium pyrophosphate dihydrate crystals. In most cases, removal of the crystals results in resolution of conductive hearing loss.

[Diffuse alveolar hemorrhage - acute, life-threatening situation in rheumatology]. / Difuzní alveolární hemoragie - akutní, zivot ohrozující stav v revmatologii.

Diffuse alveolar hemorrhage (DAH) is a life-threatening acute manifestation of systemic diseases, the most commonly of systemic vasculitis. Clinically DAH manifests by a rapidly progressive respiratory and renal failure. The decisive for diagnose is immediate bronchoscopic examination with the bronchoalveolar lavage examination. CT mostly show bilateral pulmonary infiltrates, in blood picture rapidly come to anemia. In the majority of patients it can be found positive ANCA antibodies. DAH should be suspected in the case of acute respiratory failure also in patients without history of systemic disease. On the set of 33 patients with acute DAH episode, we demonstrate the importance of rapid diagnosis and aggressive therapy. In a third of our patients was DAH the first manifestation of systemic disease. Immunomodulatory treatment must be initiated immediately after diagnose. Hospital mortality in our group was 27 %, although 42 % of the patients were required ventilation support and one-third of patients had acute renal failure. After handling of acute episode of DAH is the prognosis quoad vitam promising.Key words: bronchoalveolar fluid - diffuse alveolar haemorrhage - granulomatosis with polyangiitis - intensive care in rheumatology - vasculitis.

The plausible association of MTHFR and ADORA2A polymorphisms with nodules in rheumatoid arthritis patients treated with methotrexate.

OBJECTIVE: The treatment of rheumatoid arthritis (RA) patients with methotrexate (MTX) is linked to the development or progression of rheumatoid nodules. The aim of this study was to determine whether folate and adenosine pathways-related single nucleotide polymorphisms might be predictive of increased nodule formation in RA patients treated with oral MTX. METHODS: A total of 185 Caucasian RA patients were enrolled in this cross-sectional study, all of whom fulfilled the 1987 RA criteria of the American College of Rheumatology; each patient had a history of MTX treatment. RESULTS: A higher frequency of the MTHFR 1298AA genotype was found in 17 (70.8%) of 24 patients with general nodules [odds ratio (OR)=3.08, 95% confidence interval (CI): 1.20-7.69] and in 14 (73.7%) of 19 patients who developed nodules during MTX treatment (OR=3.55, 95% CI: 1.22-10.32). In contrast, a negative association with nodules during MTX treatment (OR=0.29, 95% CI: 0.08-1.10) was found for 19 (79.2%) patients with the TT genotype (rs2298383) in the adenosine A2a receptor gene (ADORA2A). However, the significance did not remain upon correction for multiple testing. The combination of MTHFR 1298AA along with ADORA2A rs2298383 CC or CT genotypes occurring in one-third of RA patients showed a higher frequency of general nodules 15/59 (25.4%) as well as developing nodules during MTX treatment 13/59 (22.0%) in comparison with the overall studied group: 24/185 (13.0%) and 19/185 (10.3%), respectively. CONCLUSION: This exploratory study indicates for the first time a plausible association of adenosine and folate pathways single nucleotide polymorphisms in nodules' etiopathogenesis.

Methotrexate impact on radiographic progression in biologic-treated rheumatoid arthritis under clinical remission: A case report on monozygotic Caucasian twins.

We describe Caucasian monozygotic twin brothers with rheumatoid arthritis (RA) and discuss influence of predictors to methotrexate (MTX) outcome treatment. Single nucleotide polymorphisms (SNPs) of the MTX metabolic pathways were genotyped. Twins have multiple mutations: a CC mutation of SNP 1298A>C in methylenetetrahydrofolate reductase (MTHFR) gene, CC mutations of three SNPs in the adenosine receptor gene ADORA2A (rs3761422_4217241T>C, rs2267076_4221164T>C, rs2236624_4226593T>C), and a heterozygous genotype in SNPs ATIC_rs2372536_347C>G, MTHFD1_rs2236225_1958G>A. These mutations are known to predict a worse outcome of MTX treatment. The twins had different lifestyles (alcohol drinking and smoking in Twin 1, regular coffee consumption in Twin 2), but a very similar clinical presentation of the outset of RA, radiographic scoring according to the Sharp/van der Heijde method with an almost identical antibodies presentation. The period of the patients before anti-TNFα treatment was characterized by unsuccessful per oral MTX pharmacotherapy in both cases (a low effect of MTX in Twin 1; an early discontinuation of MTX due to an adverse event in Twin 2). In both twins, the outcome of well-controlled anti-TNFα treatment (co-medication with MTX in Twin 1) for 10 years was expressed as low disease activity measured using composite index DAS28. It is interesting that Twin 2 had an unfavorable radiographic scoring after a 10-year follow-up than Twin 1 in spite of the comparable DAS28 in Twin 2 and smoking in Twin 1. In conclusion, co-medication of MTX with biologics may impact on RA radiographic progression despite predicted bad MTX outcome based on pharmacogenetic analysis.

Wireless Capsule Enteroscopy in Healthy Volunteers.

INTRODUCTION: The aim of our prospective study was to define endoscopy appearance of the small bowel in healthy volunteers. METHOD: Forty-two healthy volunteers underwent wireless capsule endoscopy, clinical investigation, laboratory tests, and completed a health-status questionnaire. All subjects were available for a 36-month clinical follow-up. RESULTS: Eleven subjects (26%) had fully normal endoscopy findings. Remaining 31 persons (74%), being asymptomatic, with normal laboratory results, had some minor findings at wireless capsule endoscopy. Most of those heterogeneous findings were detected in the small intestine (27/31; 87%), like erosions and/or multiple red spots, diminutive polyps and tiny vascular lesions. During a 36-month clinical follow-up, all these 42 healthy volunteers remained asymptomatic, with fully normal laboratory control. CONCLUSIONS: Significant part of healthy subjects had abnormal findings at wireless capsule endoscopy. These findings had no clinical relevance, as all these persons remained fully asymptomatic during a 36-month follow-up. Such an endoscopic appearance would be previously evaluated as "pathological". This is a principal report alerting that all findings of any control group of wireless capsule endoscopic studies must be evaluated with caution.

Small intestinal injury in NSAID users suffering from rheumatoid arthritis or osteoarthritis.

The goal of this prospective study was to assess non-steroidal anti-inflammatory drug (NSAID)-induced enteropathy in patients with rheumatoid arthritis (RA) or osteoarthritis (OA) by means of non-invasive wireless capsule enteroscopy. A total of 143 patients (74 with RA, 69 with OA) treated with NSAIDs (>1 month) and 42 healthy volunteers were included. All subjects underwent capsule endoscopy, laboratory tests and filled in questionnaires. The severity of small bowel injury was graded as: mild (red spots or sporadic erosions), moderate (10-20 erosions) or severe (>20 erosions or ulcers). Capsule endoscopy identified small bowel lesions in 44.8 % of patients (mild 36.4 %, moderate 3.5 % and severe in 4.9 %). Mild non-specific lesions were found in 11.9 % healthy volunteers. There was a significantly higher prevalence of enteropathy in RA (56.8 %) compared to OA (31.9 %, p < 0.01). A significant difference between NSAID users (RA and OA) with and without enteropathy was observed in erythrocytes (p < 0.01), the leucocyte count (p < 0.05), haemoglobin (p < 0.05), haematocrit (p < 0.05), serum albumin (p < 0.01) and erythrocyte sedimentation rate (p < 0.05). No relationship was found between enteropathy and dyspepsia, gender or age. NSAID therapy is associated with a significant risk of small bowel injury. The risk is significantly higher in RA patients suggesting a possible influence of the underlying disease. TRIAL REGISTRATION NUMBER: DRKS00004940.

Application of the DETECT algorithm for detection of risk of pulmonary arterial hypertension in systemic sclerosis: data from a Czech tertiary centre.

OBJECTIVE: The early, simple and reliable detection of pulmonary arterial hypertension (PAH) in SSc (DETECT) study described a new algorithm for early detection of PAH in patients with SSc. The aim of this retrospective, single-centre, cross-sectional study was to apply a modified DETECT calculator in patients with SSc in the East Bohemian region, Czech Republic, to assess the risk of PAH and to compare these results with PAH screening based on the European Society of Cardiology/European Respiratory Society (ESC/ERS) 2009 guidelines. METHODS: Sixty patients were recruited with a diagnosis of SSc (according to ACR criteria), aged 27-78 years. A modified DETECT algorithm using the modified parameter of (1.4 × right ventricle diameter)(2) in place of right atrium area was applied to all patients. Right heart catheterization (RHC) was performed in all patients with an estimated (by echocardiography) increased systolic pulmonary artery pressure ≥50 mm Hg in accordance with the ESC/ERS guidelines; however, RHC was not performed in patients solely recommended for RHC using the modified DETECT algorithm. RESULTS: Using the modified DETECT calculator, 24/58 (41.4%) patients were recommended for RHC, compared with 14/58 (24.1%) when applying the ESC/ERS 2009 guidelines. PAH was diagnosed in 7/58 (12.1%) patients. During follow-up, PAH was diagnosed in six patients. Of these, four were modified DETECT score-positive for 2 years and all for 1 year before PAH diagnosis. CONCLUSION: The modified DETECT algorithm detects all patients with PAH diagnosed according to ECS/ERS 2009 guidelines and RHC. Data of the 2-year follow-up indicate a possible positive predictive role for the modified DETECT calculator.

The impact of C677T and A1298C MTHFR polymorphisms on methotrexate therapeutic response in East Bohemian region rheumatoid arthritis patients.

Some single-nucleotide polymorphisms (SNPs) might be predictive of methotrexate (MTX) therapeutic outcome in rheumatoid arthritis (RA). The aim of this study was to determine whether SNPs in the methylenetetrahydrofolate reductase (MTHFR) gene are predictive of MTX response. Comparison was made using EULAR response criteria and according to the change of DAS28 (∆DAS28) after a 6-month MTX treatment in RA patient cohort. The two SNPs C677T (rs1801133) and A1298C (rs1801131) have been genotyped. A total of 120 patients were enrolled in the study, and all of them fulfilled the American College of Rheumatology 1987 RA criteria and are currently or previously taking MTX oral treatment, either as a monotherapy (n = 65) or in a combination with other disease-modifying antirheumatic drugs (n = 55). Genotyping was performed using qPCR allelic discrimination. We did not found any association of C677T and A1298C genotypes with MTX treatment inefficacy in dominant model (OR 1.23, 95 % CI 0.57-2.65, P = 0.697; and OR 0.98, 95 % CI 0.47-2.14, P = 1.0, respectively), or in recessive and codominant models. However, when ∆DAS28 after a 6-month therapy was used as a measure of treatment efficacy, the 677CT and 1298AC genotypes were found to be significantly associated with less favorable response to MTX (P = 0.025 and P = 0.043, respectively). In addition, even lower ∆DAS28 was determined for double-mutated 677CT-1298AC heterozygotes. It means that a synergistic effect of 677CT and 1298AC genotypes was observed. Nevertheless, the DAS28 baseline was lower here comparing to other genotypes. Unexpectedly, quite the opposite trend-i.e., better response to MTX-was found in genotypes 677CC-1298CC and 677TT-1298AA. It is an intriguing finding, because these double-mutated homozygotes are known for their low MTHFR-specific activity. Global significance was P = 0.013, η (2) = 0.160-i.e., large-size effect. Thus, our data show greater ability of 677CC-1298CC and 677TT-1298AA genotypes to respond to MTX treatment.

The VEGF and BMP-2 levels in patients with ankylosing spondylitis and the relationship to treatment with tumour necrosis factor alpha inhibitors.

INTRODUCTION: Ankylosing spondylitis (AS) is an inflammatory rheumatic disease characterized by the development of osteoproductive changes in the spine which could possibly result in ankylosis. Treatment with tumour necrosis factor alpha (TNFα) inhibitors has proved to be an important step forward in the treatment of this disease, but for the time being it is not clear whether it favourably influences radiographic progression of the disease. Vascular endothelial growth factor most probably plays a role in the development of osteoproductive changes and recently its predictive influence on radiographic progression has been demonstrated. Bone morphogenic protein 2 (BMP-2) participates in the regulation of bone proliferation and its increased serum level has been demonstrated in patients with advanced AS and correlated with the degree of radiographic changes. AIM: The study aims to evaluate the VEGF and BMP-2 levels in patients with ankylosing spondylitis and how these levels relate to the concurrent treatment with TNFα inhibitors. METHODS: Sera were evaluated from patients at the Rheumatologic Clinic of the Hradec Králové Faculty Hospital who fulfilled the modified New York Criteria for AS (n = 55). In these patients, the parameters of the activity of the disease (BASDAI = Bath Ankylosing Spondylitis Disease Activity Index, CRP = C-reactive protein) and the concurrent therapy (TNFα inhibitors, n = 21, vs. non-anti TNFα, n = 34) were recorded. The levels of VEGF and BMP-2 were analyzed using the ELISA method. RESULTS: In patients treated with TNFα inhibitors, a significantly lower VEGF level was found when compared to untreated patients (140.3 (109.4; 262.2) vs. 261 (172.4; 396.6) pg/ml; p = 0.02). No difference was found between BMP-2 levels in both groups (treated vs. untreated patients) (254.8 (2301; 267.3) vs. 261.1 (248.6; 273.5) pg/ml; p = 0.24). A correlation analysis did not reveal any relationship between VEG F and BMP-2 (r = 0.057; p = 0.68). Serum levels of VEGF correlated with serum levels of CRP (r = 0.56; p = 0.00001) and the BASDAI value (r = 0.33; p = 0.015). CONCLUSION: Significantly lower VEGF levels were found in patients treated with TNFα inhibitors versus the untreated patients. These findings are in harmony with some hitherto published analyses and may give evidence of a favourable effect of TNFα inhibitors on radiographic progression. Neither influence on the BMP-2 level by treatment with TNFα inhibitors nor correlation with VEGF levels was demonstrated.

NSAID-Induced Enteropathy in Rheumatoid Arthritis Patients with Chronic Occult Gastrointestinal Bleeding: A Prospective Capsule Endoscopy Study.

Background. The purpose of study was to evaluate the diagnostic yield of capsule endoscopy for NSAID-induced enteropathy and clinical, laboratory, and endoscopic characteristics of disease in patients with rheumatoid arthritis. Methods. 37 rheumatoid arthritis patients (30 women; mean age 55) treated with NSAIDs (>1 month), presented with anaemia and/or positive faecal occult blood testing, entered the study and underwent capsule endoscopy (EndoCapsule; Olympus), laboratory tests, and filled in questionnaires. Results. The prevalence of NSAID-induced enteropathy diagnosed by capsule endoscopy was 68% (25/37), classified as mild (red spots or erosions) in 18 (49%), moderate (10-20 erosions) in 4 (11%), and severe enteropathy (>20 erosions or ulcers) in 3 (8%) patients. We did not find statistically significant relationship between the enteropathy and gender, age, haemoglobin, leukocytes, albumin and CRP, or dyspepsia. The difference between subgroups of NSAIDs according to the COX specificity was not statistically significant. Conclusions. Capsule endoscopy is a highly accurate noninvasive method for evaluation of NSAID-induced enteropathy. It was revealed in a substantial section of the patients with rheumatoid arthritis and occult gastrointestinal bleeding, mostly classified as mild damage. No simple clinical or laboratory markers of the presence or severity of NSAID-induced enteropathy were recognised. This trial is registered with DRKS00004940.
