    ABSTRACT: Pulmonary hypertension (PH) in systemic lupus erythematosus (SLE) is associated with an unfavorable prognosis. We investigated the characteristics of SLE patients with PH. The patients with a pulmonary artery systolic pressure more than 30 mmHg at rest on echocardiogram were diagnosed with PH. Echocardiography was done only in patients with clinical or radiological evidence suggesting PH. Right heart catheterization was not performed. We identified 10 SLE patients with PH between 1980 and 2000. We compared their clinical and laboratory parameters with those of 97 consecutive SLE patients without PH. Nine of the ten patients with PH were females. The mean age at the time of SLE onset was 25.2 ± 6.9 years; the mean duration of follow-up was 93.4 ± 52.8 months, and the interval between the onset of SLE and PH diagnosis was 9.0 ± 4.6 (5-21) years. Antiphospholipid antibody positivity was significantly higher in the PH group (80 vs. 36%; p < 0.05), but there was no significant difference between two groups in regard to secondary antiphospholipid syndrome. The frequency of Raynaud's phenomenon was higher in PH group (60 vs. 27%; p < 0.05). Renal involvement (80 vs. 43%; p < 0.05), neuropsychiatric involvement (40 vs. 7.2%; p < 0.005) and serositis (70 vs. 14.4%; p < 0.001) were significantly more frequent in the PH group. The mean damage score in patients with and without PH were 4.0 ± 2.4 and 0.4 ± 1.0, respectively (p < 0.001). Four patients with PH died during the follow-up. This study reveals that the presence of PH defines a subgroup of patients with a severe disease and increased mortality. Antiphospholipid antibodies and Raynaud's phenomenon may contribute to the pathogenesis of PH. We recommend that all patients with SLE, especially those positive for antiphospholipid antibodies and/or with signs of Raynaud's phenomenon should be regularly evaluated for the development of PH.

    ABSTRACT: To evaluate damage features and impact on survival by Vasculitis Damage Index (VDI) in a cohort of Turkish patients with Wegener's granulomatosis (WG). We enrolled 50 (25 female) patients with WG according to ACR criteria. Birmingham Vasculitis Activity Score (BVAS) and VDI were used to analyze disease activity and damage. Patients had kidney (82%), upper airway (72%), lung (70%), and nervous system (15%) involvement. Median age at diagnosis was 45 years, time to diagnosis was 3.5 months, and total followup time was 35.5 months. All but one patient was positive for antineutrophil cytoplasmic antibodies (ANCA). Mean final dose and duration of corticosteroid and cyclophosphamide was 15 +/- 14 g, 39 +/- 33 months and 36 +/- 34 g, 21 +/- 2 months, respectively. Mean early (e) BVAS were 20.2 +/- 7.1 (4-38) (median 21). Mean e-BVAS and e-VDI scores at presentation and final (f)-VDI scores at last visit were 20.2 +/- 7.1 (4-38), 3.1 +/- 1.7 (median 3) (0-7) and 4.4 +/- 2.6 (0-12), consecutively. Disease related damage was prominent in kidneys (50%) and upper airways (27%). Amenorrhea (90%), cataract (28%), and diabetes (24%) were the most frequent treatment related damages. Rapidly progressive glomerulonephritis at presentation (42%) progressed to endstage renal failure in 20%. Relapses occurred in 25% with mean BVAS of 6.5 +/- 2.3 (4-11). Survival rate was 77% at 37 months. Deaths occurred early (90% in the first year). f-VDI was high in patients who relapsed (6 +/- 3 vs 3.8 +/- 2.1, p = 0.03). Logistic regression analysis demonstrated that age at time of diagnosis and e-VDI were lower in survivors with OR = 0.9 (p = 0.06, 95% CI: 0.78-1) and OR = 0.5 (p = 0.04, 95%CI: 0.25-0.98), respectively. In this cohort, e-VDI score of 5 or more was related to death with 98% sensitivity and 56% specificity (p = 0.004) (CI: 0.66-0.95). Disease related damage outweighed treatment related damage in our cohort of predominantly generalized disease activity. Early damage and older age were found to be predictors of final damage and death.

    ABSTRACT: A 17-year-old female patient presented with chronic symmetrical oligoarthritis of both knees and ankles, xerostomia, xerophthalmia, multiple bilateral lymphadenopathies in the cervical region, and bilateral parotid enlargement with the histological finding of chronic sialoadenitis. She had been already given methotrexate, chloroquine, and corticosteroids with the diagnosis of rheumatoid arthritis (RA) before referral to our outpatient clinic. Because her complaints and the lumps did not remit and she could be classified as neither RA nor primary Sjögren's syndrome (SS) according to 1987 ACR RA criteria or European preliminary criteria for SS, lymph node biopsy was repeated and revealed the diagnosis of Rosai-Dorfman disease (RDD) with the histological findings of histiocytes, phagocyting lymphocytes in enlarged sinuses, and mature plasma cells infiltrating the pulpa. All the medications were stopped after the pathological diagnosis of RDD and consulting with the Division of Hematology. She was reevaluated with magnetic resonance imaging, which showed dense infiltrative areas around knee and ankle joints, and computed tomography that showed a soft tissue mass surrounding the descending aorta and upper part of the abdominal aorta. Activated partial thromboplastin time was found to be prolonged in prebiopsy examinations, and factor XII deficiency was detected after detailed hematological evaluation. The symptoms of joint involvement were relieved with nonsteroidal antiinflammatory drugs. She has been followed-up without medication without obvious clinical or laboratory change. We herein report a patient with RDD mimicking RA and SS. We consider that RDD should be kept in mind especially in patients with resistant symptoms to conventional therapies, younger disease onset, and predominant parotid and lymph node enlargement.

    ABSTRACT: Several criteria are being used for the classification of psoriatic arthritis (PsA) and there is a lack of consensus about PsA as a separate entity. Our aim is to investigate the clinical features of our patients with a clinical diagnosis of PsA, compare the sensitivities of different classification criteria, agreement between the criteria. In this study 86 PsA patients were investigated (48 females, mean age 44). Moll and Wright criteria was fulfilled by 91%, Vasey and Espinoza criteria by 94% and modified European SpA study group criteria by 59%, classification of PsA study group criteria by 86%, modified McGonagle criteria by 96%, Fournie et al. criteria by 84% and Gladman criteria by 95%. Significant agreement was present between criteria but generally kappa-values were less than 0.5. The pattern of PsA can differ with time and the implementation of the available classification criteria showed considerable differences.

    ABSTRACT: Ankylosing spondylitis is strongly associated with HLA-B27. However, the strength of the association with HLA-B27 and the clinical features may vary in different parts of the world. The aim of this study is to compare the clinical features of AS and the frequencies of HLA-B27 and its alleles in patients from Turkey with other series. One hundred and twelve patients (72 male/40 female) fulfilling the modified New York criteria for the classification of AS and 55 (27 male/28 female) healthy controls were typed for HLA-B27 and allele frequencies by sequence specific primer (PCR/SSP) method and assessed for clinical manifestations. Male to female ratio was 1.8, mean age at disease onset was 23.5 and 24.1% of patients reported juvenile onset of symptoms. Peripheral arthritis was seen in 52.7% of patients. Family history (p=0.01) and peripheral arthritis (p=0.02) were more frequent in females and spinal involvement in males. HLA-B27 was found to be positive in 70% of patients and associated with younger mean age, uveitis and shorter time elapsed from symptom to diagnosis. The frequency of HLA-B27 alleles associated with SpA was not different between ankylosing spondylitis patients and healthy controls. Low frequency of HLA-B27 and clinical variations in ankylosing spondylitis may be due to different genetic and/or environmental factors in Turkey.

    ABSTRACT: It is reported that the usage of high-dose intravenous immunoglobulin (HD-IVIG) in systemic autoimmune diseases is associated with various adverse events in a wide range of severity. We aimed to investigate the frequency and profile of adverse events in a group of patients with diffuse connective tissue diseases and Wegener's granulomatosis (WG) who were administrated HD-IVIG for different indications. We recorded the data of 38 patients (25 females and 13 males) aged 38 +/- 15 (12-75) years who were followed up with the diagnosis of systemic autoimmune diseases between 1994 and 2006 according to a predefined protocol. Patients with active disease were treated with HD-IVIG and standard immunosuppressives concomitantly. We evaluated the occurrence of allergy, acute renal failure, thromboembolic events, neutropenia, hemolytic anemia, aseptic meningitis, and vasculitis during infusion therapy of HD-IVIG and in the following 3 weeks. We commenced a total of 130 infusions of HD-IVIG. Patients were administrated 1-12 (3.4 +/- 2.6) infusions of HD-IVIG as needed. Indications for HD-IVIG were unresponsiveness or partial response to standard treatment, severe infections along with disease activity, and severe thrombocytopenia in the preoperative period in 97, 23, and 5% of patients, respectively. Minor adverse events were seen in two patients during HD-IVIG infusions. One patient with WG developed rapidly progressive renal failure during severe disease flare between HD-IVIG infusions. Another patient with WG developed recurrence of deep-vein thrombosis during severe disease flare 3 months after HD-IVIG. Both events were attributed to severe disease activity. Adverse events like allergy, acute renal failure, thromboembolic events, hematological problems, aseptic meningitis, and vasculitis are reported in different frequencies (1-81%) in patients who were administered HD-IVIG for systemic autoimmune diseases. HD-IVIG is considered a safe treatment in selected patients assuring adequate infusion precautions.

    ABSTRACT: To investigate the role of shared epitope (SE) alleles in the short-term clinical response to leflunomide for the treatment of active RA. In an open-label, multi-centre study of 16-weeks duration, 93 patients (82% female) fulfilling ARA 1987 RA criteria were treated with leflunomide (100 mg loading dose for 3 days, then 20 mg/day as the maintenance dose). The primary efficacy criterion was the response status according to the European League Against Rheumatism (EULAR) response criteria using Disease Activity Score-28 (DAS28) activity measure. SE determinations have been undertaken by polymerase chain reaction and sequence-specific oligonucleotide genotyping methods. The mean (s.d.) Disease Activity Score-28 (DAS28) was 5.1 (1.3) before the treatment, which was significantly decreased after 16 weeks [3.0 (1.1), P < 0.001]. According to the EULAR response criteria, 55 patients (59.1%) were classified as good responders. SE was positive in 51 (54.8%) of the patients, with 13 (13.9%) having SE homozygosity or carrying any two SE alleles. Among SE-positive patients, 68.6% (35/51) were good responders, compared with 47.6% (20/42) in SE negatives (P = 0.04). No difference was present according to SE hetero- or homozygosity (68.4 vs 69.2%). RF was also present significantly more frequently in the SE-positive group compared with negatives (78.4 vs 57.1%, P = 0.03). However, no significant difference was observed in the prevalence of RF positivity in patients with a good clinical response (72.7 vs 63.2%, P = 0.32). The results suggest that HLA-DRB1 SE presence may favourably affect the outcome of leflunomide monotherapy in an unselected group of RA patients with an active disease and naive to leflunomide.

    ABSTRACT: Adult-onset Still's disease (AOSD) is a febrile disorder of unknown aetiology characterised by typical spiking fever, evanescent rash, arthralgia and leucocytosis. According to the diagnostic criteria of AOSD, we identified 84 patients between 1990 and 2003. The aim of this study was to analyse the characteristics of AOSD in Turkish patients who were followed-up in a tertiary referral centre. Of 84 patients of AOSD, 59 (70.2%) were female, 25 (29.8%) were male. Arthralgia (96.4%), fever (95.2%), arthritis (69%), sore throat (65.5%) and typical rheumatoid rash (59.5%) were the most common findings. The mean value of laboratory findings were as follows; C-reactive protein level of 11.59 +/- 6.81 mg/dl, erythrocyte sedimentation rate (ESR) of 89.05 +/- 31 mm/h, leukocyte count of 16,234.51 +/- 7785.2/microl. Leucocytosis was present in 69 patients (84.15%). Forty-eight patients had a WBC count >or= 15,000/microl. Hypoalbuminaemia was present in 35 patients. Abnormal levels of aspartate aminotransferase and alanine aminotransferase were observed in 30 patients, whereas abnormal levels of alkaline phosphatase in 16 patients. Thirty-seven patients had an ESR value of more than 100 mm/h. Thirty-two patients had a ferritin value of more than 1000 ng/dl. High fever, sore throat, rheumatoid rash, polyarthritis, hyperferritinaemia (>or= 1000 ng/ml), leucocytosis with a neutrophilic predominance, anaemia and hypoalbuminaemia were remarkable observations in the initial examination.

    ABSTRACT: The objective of this study was to investigate the frequency of antibodies against cyclic citrullinated peptides (anti-CCP) and keratin (AKA) in patients with rheumatoid arthritis (RA) as well as in patients with primary Sjögren's syndrome (pSS) and Wegener's granulomatosis (WG), who may present with rheumatoid factor (RF)-positive arthritis. The study group consisted of 46 patients with RA (26 patients were negative for RF), 32 with pSS, 22 with WG, and 40 healthy controls. The RF, anti-CCP, and AKA were detected in serum using the latex agglutination test, enzyme-linked immunosorbent assay, and indirect immunofluorescence, respectively. The agreement between those tests was evaluated by kappa test. No positive result for AKA was detected in pSS and WG patients, and anti-CCP was found in only one patient with pSS. The results of kappa tests were low, varying between 0.25 (RF-anti-CCP) and 0.02 (RF-AKA). The sensitivity and specificity values were 43 and 44% for RF, 65 and 98% for anti-CCP, and 58 and 100% for AKA, respectively, in RA patients. In the RF-negative RA group, AKA was found to have a high frequency (55%) in comparison to anti-CCP (38%). Seropositivity was found to be 87% for any one of the three autoantibodies tested in RA patients. With a higher specificity, values for RA, anti-CCP, and AKA seem to be helpful for the differential diagnosis of patients with RF-positive arthritis, which may include patients with WG and pSS, and screening of all three antibodies may increase the diagnostic performance.

    ABSTRACT: The aim of this study was to analyze and compare the demographic and clinical features and prognosis of patients with different systemic necrotizing vasculitides (SNV) in Turkey. Twenty-three patients with Wegener's granulomatosis (WG), 15 with polyarteritis nodosa (PAN), and two with Churg-Strauss syndrome were included in the study. The clinical and laboratory features of patients with WG and PAN were compared, and survival analysis was performed for the WG patients. Twenty-one patients with WG had systemic disease involving kidneys, and two had localized disease. Fifteen patients were placed in the PAN group, 12 of whom were classified as having classic PAN and three with microscopic polyangiitis. Median follow-up time was 37 months (range 1-81) for WG patients and 41 months (range 5-132) for the PAN group. Upper respiratory tract, pulmonary, and renal involvement were significantly more frequent in the WG group than in PAN. Peripheral nervous system involvement was more frequent in the PAN group. In WG, survival was calculated as 59% at 35 months. High initial vasculitis damage index scores were found to be predictive for mortality. This study revealed that the most frequent type of SNV was WG in a tertiary rheumatology setting in Turkey. There was initial organ damage in most of the patients, frequently caused by severe renal involvement. In contrast to other published series, overt cardiovascular and gastrointestinal involvement were not observed in our patients with SNV.

    ABSTRACT: This study investigates the clinical and demographic characteristics of familial Mediterranean fever (FMF) patients with and without amyloidosis. The clinical data of 503 patients with FMF (females:males 250:253) were reviewed. Fifty of these patients had amyloidosis (f:m 23:27). The ages of attack onset in patients with and without amyloidosis were 7.8+/-6.2 and 11.1+/-8.5, respectively (P<0.05). The time between disease onset and diagnosis was longer in patients with amyloidosis than those without (187.6+/-99.4 months and 132.5+/-110.2 months, respectively, P<0.001). More patients in the amyloidosis group had positive family histories of FMF (68% vs 54%, P<0.05). The frequencies of chest pain (78% vs 51%, P<0.001), arthritis ( 80% vs 60%, P<0.01), and erysipelas-like erythema (44% vs 16%, P<0.001) were higher in the amyloidosis group. In the amyloidosis group, FMF-related manifestations of chest pain, arthritis, and erysipelas-like erythema are more frequent. Our results also support that long periods between disease onset and diagnosis are associated with a high risk of developing amyloidosis.

    ABSTRACT: We aimed to investigate the efficacy and safety profile of high-dose intravenous immunoglobulin (HD-IVIG) therapy in patients with severe systemic lupus erythematosus (SLE), inflammatory muscle disease (IMD), Wegener's granulomatosis (WG), and/or concurrent infection who failed to respond to standard therapies. We evaluated the records of eight patients with SLE, eight with IMD, and four with WG who were treated with HD-IVIG (2 g/kg per month for 1-12 months) for active disease in 19 patients and concurrent infection in three (mycobacterial in two with SLE and cytomegaloviral in one with WG). Systemic lupus erythematosus disease activity index (SLEDAI) scores before and after HD-IVIG were statistically analysed. Remission was achieved in 14 cases (70%). The SLEDAI scores significantly decreased in patients with SLE (P=0.02). No serious side effect was observed. High-dose IVIG may be used as an adjunctive treatment in connective tissue diseases that do not respond to standard therapies or as alternative treatment for patients with concurrent severe infections or for whom immunosuppressives are contraindicated.

    ABSTRACT: Systemic lupus erythematosus (SLE) is a multi-system autoimmune disorder mainly affecting young women. In this study, we aimed at investigating the clinical, laboratory and management characteristics of our SLE patients with an age of onset > or =50. Twenty patients with late onset SLE (> or =50 years) were identified from the records, on the basis of their first SLE-related symptoms (Group I). A hundred consecutive SLE patients with initial symptoms before the age of 50 were also selected as controls (Group II). Clinical, laboratory and management characteristics of the patients were recorded according to pre-defined protocol and compared by chi(2), Student's t-test and Fisher's exact test. Comparison of the demographic findings between the Group I (F/M: 18/2) and the Group II (F/M: 90/10) were as follows: the mean age of disease onset was 53.9 +/- 4.5 years vs. 26.3 +/- 9.2 years, mean time of follow-up was 44.2 +/- 40.5 months vs. 50.1 +/- 47.4 months, mean damage index was 0.6 +/- 0.6 vs. 0.58 +/- 1.4. There was no significant difference between the two groups with regard to clinical, laboratory parameters, damage index and immunosuppressive treatment characteristics. SLE-related manifestations were similar in two groups except fever (10% in the Group I vs. 41% in the Group II; p = 0.01). The only two patients with pulmonary fibrosis were found in the Group I (p = 0.027). The clinical and laboratory characteristics and the disease outcome in SLE patients with an age of onset > or =50 years did not show significant differences from the control SLE patients with a younger age of onset.

    ABSTRACT: It has been generally accepted that the clinical onset of familial Mediterranean fever (FMF) begins before 20 years of age in most patients. In this study, we aimed to investigate the demographic and clinical characteristics of our FMF patients with an age of onset > or =20. Records of 401 patients (female/male: 204/197) that followed up between 1990 and 1999 were reviewed according to a pre-defined protocol. All patients fulfilled the diagnostic criteria of Livneh et al. The demographic and clinical features of adult-onset FMF patients were compared to those of patients with a disease onset before 20 years of age. There were 57 patients (14%) who experienced symptoms of FMF at > or =20 years of age; 34 of them (8.5%) reported their first attack between 20 and 29 years of age; 18 of them (4.5%) between 30 and 39 years of age and five patients (1.25%) had their first attack after 40 years of age. Arthritis (42 vs. 65%, p = 0.001) and erysipelas-like erythema (7 vs. 17%, p = 0.047) were significantly less frequent in patients with adult-onset FMF compared to patients with disease onset before 20 years of age. Arthritis and erysipelas-like erythema were less frequent in adult-onset patients compared to those with an earlier disease onset. Adult-onset FMF may be a form of disease with distinct clinical, demographic and molecular characteristics. Prospective clinical studies and investigation of genotypic features are needed to identify the characteristics of this phenotypic variant.

    ABSTRACT: The frequency and the distribution of HLA-B27 subtypes in spondylarthropathy (SpA) patients and controls were investigated in a sample Turkish population. B27 subtyping was performed by PCR-SSP method in two groups: 49 unrelated HLA-B27 positive Turkish patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group Criteria, and 55 HLA-B27 positive healthy controls. The frequency of HLA-B*27 was 2.6% in the Turkish population, and B*2705 was the predominant allele among patients with SpA. The difference was mainly between male patients and male controls The proportion of B*2705 among B27-positive patients and controls was significantly different (P=0.02). Our study supports other reports from different populations which showed that B*2705 and B*2702 were more frequent in Caucasian patients with SpA.

    ABSTRACT: The objective was to investigate the frequency and characteristics of tuberculosis (TB) in patients with systemic lupus erythematosus (SLE). We reviewed the charts of 556 patients with SLE who were followed up between 1978 and 2001 in our lupus clinic. Patients who developed TB after the diagnosis of SLE were identified (SLE/TB+). Ninety-six consecutive patients with SLE who did not develop TB during the follow-up were evaluated as a control group (SLE/TB-). Clinical, laboratory and management characteristics of these two groups of patients were recorded according to a predefined protocol, and compared. Of the 556 patients evaluated, 20 patients (3.6%) with TB were identified. Nine of the 20 patients (45%) had extrapulmonary TB (vertebral involvement in three patients, meningeal in two, and joint and soft tissue in four). Arthritis and renal involvement were significantly high in the SLE/TB+ group (P = 0.045, P = 0.009, respectively). The mean daily dose of prednisolone before the diagnosis of TB and the cumulative dose of prednisolone were significantly higher in the SLE/TB+ group compared to the SLE/TB- group (27 +/- 22 g versus 16 +/- 16 g, 24 +/- 45 mg versus 11 +/- 8.5 mg, respectively). In conclusion, we found an increased frequency of TB infection and a high prevalence of extrapulmonary TB in a large cohort of SLE patients. The mean daily dose of prednisolone before the diagnosis of TB and the cumulative dose of prednisolone, which possibly related to disease severity, were important determinants for the increased risk of TB in these patients with SLE.
