Anti-Phosphatidylethanolamine and Anti-Phosphatidylserine Antibodies-Association with Renal Involvement, Atherosclerosis, Cardiovascular Manifestations, Raynaud Phenomenon and Disease Activity in Polish Patients with Systemic Lupus Erythematosus.

OBJECTIVE: To evaluate the association between anti-phosphatidylethanolamine (aPE) and anti-phosphatidylserine (aPS) antibodies and cardiovascular risk, organ involvement and disease activity in systemic lupus erythematosus (SLE) patients. METHODS: We studied 93 SLE patients and 30 controls. We analyzed levels of anti-phospholipid antibodies, including aPS and aPE, the profiles of antinuclear, anti-neutrophil cytoplasmic (ANCA) and anti-endothelial antibodies, carotid intima-media thickness (cITM) and atherosclerotic plaque presence, ankle-brachial and high resistance indices, atherosclerotic risk factors, organ manifestations and treatment. RESULTS: Levels of aPS and aPE were significantly higher in SLE patients in comparison with the controls (p = 0.038 and p = 0.044, respectively). aPS was associated with the risk of Raynaud's phenomenon (p = 0.021) development. aPE increased the risk of renal involvement (p = 0.049), cerebral stroke (p = 0.050), high vlues of cIMT (p = 0.041) development as well as occurrence of selected serological markers associated with activity of the disease such as anti-double stranded DNA (p = 0.021). The long duration of regular smoking (p = 0.021) and the high number of cigarettes/day (p = 0.015) were significantly associated with the risk of aPE occurrence. CONCLUSIONS: Patients with aPS and aPE are at risk of vascular involvement. Especially the presence of aPE may significantly increase the risk of thrombotic complications development in SLE patients without classical serological markers of APS. Finally, aPE might be used as a marker of disease activity and risk of renal injury development in this patient group. The classical atherosclerotic markers including lipid indices play an important role in complex analysis of cardiovascular risk in lupus patients and enable to identify patients at the highest risk and implement effective preventive, diagnostic and therapeutic procedures.

Respiratory involvement in antineutrophil cytoplasmic antibody-associated vasculitides: a retrospective study based on POLVAS registry.

OBJECTIVES: The study aimed to characterise the Polish population of (ANCA)-associated vasculitides (AAV) with respiratory involvement (RI), in comparison to the subgroup without lung manifestations and the other cohorts. METHODS: Retrospective analysis of the Polish population of AAV with RI was conducted, based on data from the POLVAS registry. Standard descriptive statistics, χ2 test, and Mann-Whitney U test were used to perform comparisons. RESULTS: Among 461 cases qualified to this study, there were 316 cases with RI (68.5%), 206 with granulomatosis with polyangiitis (GPA) (65.2%), 80 with eosinophilic granulomatosis with polyangiitis (EGPA) (25.3%) and 30 with microscopic polyangiitis (MPA) (9.5%). Proportion of RI in GPA, MPA, and EGPA accounted for 67.8%; 40.0%; 97.6%, respectively. The number of relapses was higher in the RI group (median 1.0 vs. 0.0; p=0.01). In the subgroup of combined GPA and MPA with RI, the trends toward higher proportion of deaths (11.7% vs. 5.7%; p=0.07), relapses requiring hospitalisation (52.2% vs. 42.4%, p=0.07) and relapses requiring admission to the intensive care unit (5.6% vs. 1.4%, p=0.09) were observed, median maximal concentration of CRP was higher (46 vs. 25 mg/l; p=0.01) and more aggressive treatment was administered. CONCLUSIONS: Prevalence of RI in the Polish population of AAV is similar to the values reported in the literature, however, the proportion observed in GPA is closer to those presented in Asian than Western European cohorts. RI seems to be associated with a more severe course of disease and its presence prompts more aggressive treatment.

Association of antineutrophil cytoplasmic antibody (ANCA) specificity with demographic and clinical characteristics of patients with ANCA­associated vasculitides.

INTRODUCTION: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by the presence of proteinase­3 (PR3) or myeloperoxidase (MPO) ANCA. In over 90% of cases, PR3­ANCA is associated with granulomatosis with polyangiitis (GPA). However, it is also rarely found in microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). On the other hand, MPO­ANCA being characteristic of MPA (>90% of cases), is also found in about 40% of EGPA and 5% of GPA patients. On the ground of this overlap, clinical importance of ANCA specificity identification has been questioned. OBJECTIVES: In this study, we analyzed the clinical and demographic characteristics of AAV subgroups identified by ANCA serotype. PATIENTS AND METHODS: We conducted a multicenter study of AAV patients (417 GPA, 106 MPA, 102 EGPA; diagnosed between 1990 and 2016), included in the POLVAS registry. The data were systematically collected according to a standardized protocol. RESULTS: In the ANCA-positive group (anti­MPO, anti­PR3) a male-to-female ratio was 1:1, whereas in the ANCA-negative group it was 1:2, regardless of AAV diagnosis. Anti­MPO antibodies were present in significantly older patients. Patients with MPO+GPA and MPO+EGPA were older than those with corresponding ANCA­negative GPA and EGPA as well as PR3+AAV. Moreover, ANCA­negative AAV was characterized by a low risk of end­stage kidney disease and death. CONCLUSIONS: The presence and specificity of ANCA in AAV patients are related to sex and age, determine their organ involvement and influence mortality as previously shown. Patients with MPO­ANCA-positive AAV constitute a clinically homogeneous group, whereas PR3­ANCA-positive patients are much more clinically heterogeneous. ANCA-negative AAV patients are characterized by better prognosis. Thus, ANCA identification is an indispensable element and should not be omitted in establishing AAV diagnosis.

ANCA-associated vasculitis patients treated in Polish intensive care units - retrospective characteristics based on the POLVAS registry.

INTRODUCTION: ANCA-associated vasculitides (AAV) is a group of rare disorders where inflammation and damage of the small blood vessels lead to dysfunction of the supplied organs. In severe flares of the disease patients may require intensive care unit (ICU) admission and treatment. The study aims to characterize Polish patients with AAV who were admitted to the ICU and compare them to the others. MATERIAL AND METHODS: An observational, retrospective study based on the POLVAS - registry of Polish adult patients with AAV was carried out. Patients admitted to the ICU (ICU group) were identified and compared with the patients who did not require ICU admission (non-ICU group). Characteristics and comparison between groups were made using standard statistic descriptive methods. RESULTS: 30 patients admitted to the ICU were identified among 573 cases included in the registry. All patients in the ICU group with available data were ANCA positive. The clinical manifestations related to the ICU admission were respiratory, renal and central nervous system involvement. The treatment regimen for remission induction was similar in both groups. Almost half of the patients in the ICU-group (48.3%) required dialysis, whereas in the non-ICU group it was 21.8% (P = 0.01). Infections were also more frequent in the ICU group (72.4% vs. 36.9% P < 0.001). The mortality rate among patients who needed ICU treatment was significantly higher when compared to the rest of the patients (53.6% vs. 7.8%; P < 0.001). CONCLUSIONS: In the Polish AAV cohort one in twenty patients required ICU admission. This group was characterized by multiple organ involvement and high mortality.

Treatment and its side effects in ANCA-associated vasculitides - Study based on POLVAS registry data.

PURPOSE: The aim of this study is to present the treatment modalities and associated side effects in a Polish nation-wide ANCA-associated vasculitides (AAV) patients' cohort. MATERIALS AND METHODS: Retrospective analysis of patients diagnosed with AAV between 1990 and 2016, included in the POLVAS registry was performed. Standard descriptive statistic methods were used with an emphasis on the treatment modalities. RESULTS: There were 625 patients diagnosed with AAV included in this study: 417 cases of granulomatosis with polyangiitis (GPA; 66.7%), 106 cases of microscopic polyangiitis (MPA; 17.0%) and 102 cases of eosinophilic granulomatosis with polyangiitis (EGPA; 16.3%). The mean age at the date of diagnosis was 50.4 (±15.7) years and the median observational period amounted to 4.0 (2.0-8.0) years. Glucocorticosteroids (GCs) were the medicaments most frequently used for remission induction (593/622; 95.3%), followed by cyclophosphamide (487/622; 78.3%), rituximab (44/622; 7.1%), and methotrexate (39/622; 6.3%). GCs were also most frequently administered for maintenance therapy (499/592; 84.3%), followed by azathioprine (224/592; 37.8%), methotrexate (136/592; 23.0%) and mycophenolate mofetil (99/592; 16.7%). The median cumulative doses of cyclophosphamide and rituximab equalled 7.99 g (4.18-14.0) and 2000 mg (1500-2800), respectively. The most commonly observed adverse events included: infections - 214/551 cases (38.8%), which were associated with the time of observation (OR = 1.05; 95% CI 1.01-1.10), the use of GCs intravenous pulses (OR = 2.76; 95% CI 1.68-4.54) and need for haemodialysis (OR = 1.73; 95% CI 1.10-2.71). CONCLUSIONS: Polish patients with AAV were predominantly treated according to appropriate guidelines. The most frequent adverse events were typical for usually administered immunosuppressive treatment.

Serum Interleukin-23 in Polish Patients with Systemic Lupus Erythematosus: Association with Lupus Nephritis, Obesity, and Peripheral Vascular Disease.

OBJECTIVES: To analyze the correlation between the serum concentration of interleukin- (IL-) 23 and atherosclerotic changes, traditional atherosclerotic risk factors, the autoantibody profile, and involvement of selected organs in systemic lupus erythematosus (SLE) patients. PATIENTS AND METHODS: We studied 94 SLE patients and 27 controls. We analyzed the IL-23 serum concentration, autoantibodies, carotid intima-media thickness and atherosclerotic plaque, the ankle-brachial index, atherosclerotic risk factors, and organ manifestations. RESULTS: Concentrations of IL-23 significantly differed between SLE patients and the controls (p = 0.0015). On the basis of multivariate stepwise analysis, we revealed that high levels of IL-23 were associated with atherosclerotic plaque in common femoral arteries (OR = 12.67; 95% CI: 1.41-113.84), lupus nephritis (OR = 3.69; 95% CI: 1.16-12.22), and obesity (OR = 4.21; 95% CI: 1.40-12.67). Autoantibodies related to IL-23 were anti-phosphatidylethanolamine antibodies (OR = 11.06; 95% CI: 1.24-98.65) and anti-SS-B/La antibodies (OR = 15.43; 95% CI: 1.73-137.25). CONCLUSIONS: IL-23 may be involved in lupus nephritis pathogenesis. Through its association with obesity and selected antiphospholipid antibodies, IL-23 might promote a hypercoagulable state contributing to atherothrombosis development in SLE patients.

[Adverse effects of cyclosporin a observed in rheumatoid arthritis and psoriatic arthritis]. / Dzialania niepozadane w czasie leczenia cyklosporyna a u chorych na reumatoidalne i Luszczycowe zapalenie stawów-obserwacje wlasne.

INTRODUCTION: Rheumatoid arthritis (RA) and psoriatic arthritis (PA) represent diseases which often demand aggressive therapy in order to control the process and inhibit lesion formation in joints and organs. This kind of therapy can be achieved with cyclosporin A (CsA), particularly when combined with methotrexate (MTX). This combination is far more effective than single-drug therapy and is capable of significantly reducing the number of articular lesions. Considering the fact that monotherapy is associated with many adverse effects, it is feared that both drugs in combination may produce cumulative toxicity. The aim of this work was to determine the frequency of adverse effects caused by CsA in patients treated for RA and PA at the Outpatient Rheumatology Clinic of the First Public Hospital in Szczecin. MATERIAL AND METHODS: Our study group consisted of 61 patients, including 47 with RA--35 females, mean age 51 yrs (range: 21-69 yrs), mean disease duration 9.9 yrs (range: 2-23 yrs); 12 males, mean age 51.8 yrs (range: 33-74 yrs), mean disease duration 8 yrs (range: 3-14 yrs) and 14 with PA--6 females, mean age 41.1 yrs (range: 33-55 yrs), mean disease duration 7.8 yrs (range: 2-16 yrs); 8 males, mean age 42.9 yrs (range: 35-50 yrs), mean disease duration 7.0 yrs (range: 0.5-21 yrs). All patients were on MTX. During 11 years of follow-up, CsA was withdrawn due to adverse effects in 20 patients (32.8%). The following adverse effects were observed: arterial hypertension (n=19), hand tremor (n=11), hirsutism (n=7), elevated creatinine (n=17), gingival hypertrophy (n=9), abnormal appetite (n=2), peripheral neuropathy (n=1), lymphocytosis (n=1), skin lesions (n=1), diarrhea (n=2), recurrent infections (n=1), candidiasis (n=1), zoster (n=1), and neoplasm (n=2). Adverse effects responsible for withdrawal of CsA in 14 patients (23%) appeared more frequently during the first 12 months of therapy. Our observations indicate that CsA is well tolerated. The majority of adverse effects subsided after dose reduction or temporary withdrawal of the drug.

[Cardiovascular manifestations of seronegative inflammatory spondyloarthropathies]. / Zmiany w ukladzie sercowo-naczyniowym w przebiegu seronegatywnych spondyloartropatii zapalnych.

Cardiovascular manifestations of seronegative spondyloarthropathies represent an important clinical problem which has not been fully elucidated. Clinically significant cardiovascular symptoms are present in 10% of patients with ankylosing spondylitis (AS), usually in the case of long-standing disease. The following echocardiographic abnormalities have been reported in AS: ascending aortitis, aortic insufficiency (1-34%), mitral insufficiency (1-76%), mitral valve prolapse (5.7-10%), and diastolic dysfunction (20-50%). Abnormalities of the cardiac conduction system may develop in 1% to 33% of AS patients as a consequence of postinflammatory scarring of the myocardium. Cardiovascular diseases are the leading cause of death (36.2%) of patients with psoriatic arthritis (PsA). The risk of death in PsA is 1.3 times greater than in the general population. The following echocardiographic abnormalities can be seen in PsA: fibrinous pericarditis (18.2%), myocarditis (15.9%), and valvular disease (5.7%). Diastolic dysfunction in PsA correlates with the presence of articular lesions and duration of psoriasis. The importance of a thorough investigation of the cardiovascular system in patients with seronegative spondyloarthropathies is emphasized.

[Glottis morphology in rheumatoid arthritis]. / Morfologia glosni w reumatoidalnym zapaleniu stawów.

UNLABELLED: Rheumatoid arthritis (RA) is an inflammatory disease of the connective tissue, which can affect larynx and cricoarytenoid (CA) joints, as well. The AIM of this study was assessment of 1) glottis morphology and frequency of laryngeal structures involvement in RA of peripheral joints and 2) evaluation of rheumatoid patients' complaints which can indicate the laryngeal involvement. MATERIAL: 77 patients were examined (71 women and 16 men) in the age from 19 to 77 (mean 56,69). RA duration was from 1 month to 29 years (mean 9,38). RA was active in 61% of patients. METHOD: Anamnesis, physical examination, videolaryngoscopy, computer tomography, electromyography. RESULTS: The most frequent complaints were: foreign body sensation in the throat (51%), hoarseness (47%) with accompanying weakness of voice and dysphagia. In videolaryngoscopic examination swelling and/or redness of mucosal tissue in CA area was observed in 45% of patients. In 3 women impairment of vocal folds was stated, in 1 it was limitation of right vocal fold mobility and in 2 bilateral vocal folds immobility and tracheotomy was necessary. In patients with active RA and with foreign body sensation in the throat significantly more often inflammatory changes in larynx were visible. CONCLUSIONS: 1. Rheumatoid inflammation in the larynx is demonstrated by swelling and/or redness of mucosal tissue in CA area and in some individuals by its immobilization. 2. In the periods of RA intensification complains of foreign body sensation in the throat and hoarseness may indicate on laryngeal involvement. Our study results justify a suggestion of continuation of the morphological and functional changes estimation in patients with peripheral RA.

Cardiac arrhythmias and conduction disturbances in patients with ankylosing spondylitis.

Conduction disturbances, aortic incompetence, and myocardial fibrosis are known complications in adult patients with ankylosing spondylitis (AS). Its incidence has been reported to be 10% to 30%; however, less attention has been paid to all cardiac arrhythmias. The aim of this study was to evaluate arrhythmias and conduction disturbances in patients with AS using electrocardiograms and Holter monitoring (including heart rate variability analysis) and to estimate its relationships with age, gender, clinical features, and duration of AS. Thirty-one patients with AS (20 to 69 years old, mean 50 +/- 14) and 22 healthy volunteers (26 to 69 years old, mean 49 +/- 13) underwent rheumatologic and cardiologic evaluations. Ventricular extrasystoles were present in 55% of AS patients and in 28% of controls. Supraventricular extrasystoles were present in 94% of AS patients and 100% of controls. The frequency of ventricular extrasystoles was found to be higher in the AS patients than in the control subjects. Significant differences were found in heart rate variability analyses: ultra low-frequency power and root mean square recessive difference (r-MSSD) were lower in the AS group. When the AS group was divided into subgroups (stages 3 and 4), significant differences were found between control subjects and stage 3 patients in PR interval, heart rate (HR), T-wave duration, ultra low frequency, and r-MSSD and between controls and stage 4 patients in HR, T-wave duration, and r-MSSD. QTc and QTd were not significantly different in groups and subgroups and were not correlated with any other clinical or electrocardiographic parameter. Cardiac arrhythmias were more frequent in patients with AS than in the healthy population. Simple electrocardiograms and Holter parameters do not correlate with the incidence of VESs, age, gender, clinical features, and duration of AS.

[Activity of the disease and selected echocardiographic abnormalities in ankylosing spondylitis]. / Wystepowanie wybranych zmian w badaniu echokardiograficznym u chorych na zesztywniajace zapalenie stawów kregoslupa w zaleznosci od aktywnosci choroby.

UNLABELLED: Cardiovascular involvement in the course of ankylosing spondylitis (AS) is a very important problem. The aim was to assess the influence of the activity of the disease on echocardiographic abnormalities in ankylosing spondylitis. MATERIAL AND METHODS: We studied 38 AS patients. Activity of the disease was assessed according to the ESR and following indexes: BASMI, BASFI, BASDAI, BASG-t, BASG-6. Using 2-dimensional echo Doppler (Acuson 128XP) the heart dimensions were determined according to the American Society of Echocardiography guidelines. RESULTS: Patients with mitral valve prolapse compared with the group of the AS patients without this abnormality had significant higher (p = 0.05) activity of the disease assessed by ESR. Patients with aortic incompetence compared with the group of the AS patients without this abnormality, had significant (p = 0.04) lower disease activity assessed by BASG-6. We found significant negative correlation between EF and disease duration, and significant lower disease activity assessed by BA SG-6. Patients with pericardial effusion compared with group without this had significant shorter (p = 0.05) disease duration. CONCLUSION: There was no significant influence of the following indexes: BASMI, BASFI, BASDAI, BASG-t, BASG-6 of the activity of the disease on echocardiographic abnormalities in ankylosing spondylitis.

[SAPHO syndrome--clinical features]. / Zespól SAPHO--obraz kliniczny.

OBJECTIVE: Presentation of clinical features of the SAPHO syndrome. MATERIALS AND METHODS: Seventeen patients (15 women and 2 men) with confirmed diagnosis of the SAPHO syndrome was presented. The culture of biopsy of pustulotic skin lesions was performed in 11 patients. ESR, C-reactive protein level and Waaler-Rose test were determined in all patients, and antinuclear antibodies and bone scintigraphy were performed in 16 patients. X-ray of the sterno-clavicular joints was performed in 15 patients. RESULTS: The age of patients was 22-59 yr. (mean: 47.1 yr). The duration of joint symptoms was 0.1-25 yr. (mean: 4.4 years). Pustulosis was presented in 16 patients, only 1 patient had acne. All patients suffered from pain localized on the anterior chest wall. Tenderness of the peripheral joints: wrist (in 7 patients), shoulder (in 7 patients), knee (in 4 patients) was shown. In 6 patients, skin changes preceded joint symptoms, in 2 patients skin changes followed joint symptoms after 5 and 10 yr., respectively. All patients had negative the Waaler-Rose test. Active inflammatory process characterized by an increased ESR and C-reactive protein level was present in 12 patients. Abnormalities in x-ray of the sterno-clavicular joints were present in 4 patients. Characteristic alternations for the SAPHO syndrome in scintigraphic picture of the skeleton were observed in 14 patients. All patients were treated with non-steroidal anti-inflammatory drugs. In 8 patients, treatment with antibiotics, in 11 patients--with sulfasalazine, in 3 patients--with methotrexate and low doses of glucocorticosteroids, in 1 patient--with colchicines was performed. CONCLUSIONS: Association of typical skin changes with pain of the anterior chest wall is the key for diagnosis of the SAPHO syndrome. It seems that this syndrome is more common in Poland than it has been previously estimated.

[Quality of life and activity of disease in patients with rheumatoid arthritis]. / Jakosc izycia i aktywnosc choroby u chorych na reumatoidalne zapalenie stawów.

PURPOSE: The aim of this study was to evaluate the quality of life in patients with rheumatoid arthritis (RA) considering their age, activity of the disease, its duration and radiological stage. MATERIAL AND METHODS: The study group consisted of 151 women (mean age 55.0 years, mean duration of RA 9.4 years) and 45 men (mean age 55.0 years, mean duration of RA 9.4 years). All subjects were treated at the Department of Rheumatology and at the SPSK-1 rheumatology outpatient clinic in Szczecin. Diagnosis of RA was established according to ARA criteria of 1987. The radiological stage of the disease was established according to Steinbrocker's criteria. The patient's quality of life was evaluated with the Health Assessment Questionnaire. The activity of RA was determined with the Disease Activity Score DAS 28. RESULTS: Significant correlation between HAQ score and DAS 28 was found (correlation coefficient--R = 0.38; p < 0.001). Age (R = 0.31, p < 0.001) and radiological stage of RA (R = 0.26, p < 0.001) were also found to affect the quality of life. CONCLUSIONS: The quality of life of patients with rheumatoid arthritis is significantly influenced by their age, activity of the disease, and radiological stage of RA.

[Adult-onset Still's disease]. / Choroba Stilla u doroslych.

INTRODUCTION: The authors present the course and manifestations of adult-onset Still's disease on the basis of five cases diagnosed at the Department of Rheumatology, Pomeranian Medical University in Szczecin. MATERIAL AND METHODS: The usefulness of two most popular sets of diagnostic criteria of adult-onset Still's disease (Yamaguchi and Cush) was analyzed. At onset of the disease, two out of five patients met both sets of the diagnostic criteria, two others met criteria of Yamaguchi and one of Cush. During follow-up, criteria of Yamaguchi were met in all cases. RESULTS: The authors suggest to use the Cushs criteria of adult-onset Still's disease when the patient does not meet the criteria of Yamaguchi and other causes of fever are excluded.

[Fixation of the crico-arythenoid joints in rheumatoid arthritis--preliminary report]. / Unieruchomienie w stawach pierscienno-nalewkowych w przebiegu reumatoidalnego zapalenia stawów--doniesienie wstepne.

Rheumatoid arthritis (RA) is a systemic disease of connective tissue which affects joints lined with synovial membrane. Laryngeal joints also have such a structure. Among all reasons leading to their inflammation rheumatoid arthritis is mentioned on the first place. In larynx RA mostly affects cricoarythenoid joints (CA). RA of the CA joints is found in 27% to 78% suffering from RA. In the acute phase of the disease patients complain of burning and foreign body sensation in the throat, hoarseness, pain on speaking, voice fatigability, problems with swallowing. Chronic RA of the CA joints can lead to their fixation and dyspnoea, requiring emergency tracheotomy. According to the literature, this state occurs in 10% to 25% patients suffering from RA. A case of 75 years old woman is presented, who was admitted to our Clinic with severe inspiratory dyspnoea requiring tracheotomy. She was suffering from RA for 26 years. She complained of effort dyspnoea, problems with swallowing and tightness sensation in the throat for 4 years. Patient complained also about cervical spine pain, upper right extremity and knee joint periodic oedema. The patient was suffering from so severe lower extremities pain and rheumatoid changes in knee joints that she had to walk on crutches. Little hands' joints were deformed with significant ulnarisation. Videolaryngostroboscopic examination showed no movement in CA joints, paramedian position of the vocal folds and narrowing of the glottic rim to 1.5 mm. Phonatory mobility of the vocal folds was preserved. Electromiographic examination of the internal laryngeal muscles made a) during phonation--showed bilateral normal bioelectrical record from thyroarythenoid muscles, b) at rest--there was no denervation activity. In computerized tomography study no degenerative changes in CA joints were found. On the basis of clinical view and examinations results, there was considered that fixation in CA joints was due to degenerative changes, which were the result of their rheumatoid inflammation. It was emphasized that this subject has been mentioned only several times in laryngological and phoniatric handbooks and in few articles.

The urinary excretion of pyridinoline and deoxypyridinoline during rheumatoid arthritis therapy with infliximab.

Rheumatoid arthritis is a systemic disease that causes inflammation and joint destruction. As a result of pathological destruction in bone and cartilage, crosslinks in collagen are resorbed more rapidly. This causes a rise in circulating collagen crosslink levels and their urinary excretion. In RA, apart from the crosslink resorption at the site of inflamed joints, there may be increased resorption due to general bone loss associated with disease activity. The aim of this study was to evaluate the influence of therapy with infliximab on urinary excretion of pyridinoline (PYD) and deoxypyridinoline (DPYR) as a markers of collagen degradation and its correlation with clinical and biochemical parameters of disease activity. Seventeen patients with active rheumatoid arthritis treated with infliximab were recruited into the study. The therapy resulted in the reduction in the symptoms of RA and urinary excretion of PYD and DPYR. The urinary excretion of PYD correlated with a number of swollen joints, morning stiffness, CRP and ESR. The urinary excretion of DPYR correlated during infliximab therapy with the number of swollen and tender joints and morning stiffness. The measurement of urinary excretion of PYR and DPYR may give insight into bone metabolism and help us to better understand the actual changes in bone and cartilage caused by RA and its treatment.
