Comparison of demographic, clinic and radiological features of patients with axial spondyloarthritis accompanying familial Mediterranean fever to patients with each condition alone.

OBJECTIVE: To compare the demographic, clinical, and radiological features of patients with axial spondyloarthritis (axSpA) accompanying familial Mediterranean fever (FMF) to patients with each condition alone. METHOD: Hacettepe University Hospital database was screened regarding ICD-10 codes for FMF (E85.0) and axSpA (M45). The diagnosis of FMF was confirmed by Tel-Hashomer criteria, and axSpA by the presence of sacroiliitis according to the modified New York criteria or active sacroiliitis on magnetic resonance imaging. As control groups, 136 gender-matched, consequent FMF patients without axSpA and 102 consequent axSpA patients without FMF previously treated with any biological agents were included in the analysis. RESULTS: In patients with FMF + axSpA compared to the axSpA group, age at axSpA symptom onset and age at diagnosis were lower [median with interquartile range (IQR): 21 (17-30) vs 27 (21-37), p < 0.001; 23 (21-38) vs 32 (24-43) years, p = 0.001], moderate to severe hip disease and total hip replacement were more prevalent (23.4% vs 4.7%, p < 0.001; 11.2% vs 2.8%, p = 0.016). In patients with FMF + axSpA compared to the FMF group, age at FMF symptom onset and age at diagnosis were higher [13 (6-30) vs 11 (5-18), p = 0.057; 23 (13-33) vs 18 (10-31) years, p = 0.033] and amyloidosis was more prevalent (6.6% vs 2.2%, p = 0.076). Although the M694V variant (in one or two alleles) was more prevalent in the FMF + axSpA group, the difference was not statistically significant. CONCLUSION: In patients with FMF + axSpA, the age of onset of axSpA was significantly earlier, moderate to severe hip involvement and amyloidosis were more common than in patients with each condition alone.

Comparing immunoglobulin A vasculitis (Henoch-Schönlein purpura) in children and adults: a single-centre study from Turkey.

OBJECTIVE: Immunoglobulin A vasculitis/Henoch-Schönlein purpura (IgAV/HSP) is a systemic vasculitis involving small vessels with the deposition of immune complexes containing IgA. It is the most common primary systemic vasculitis of childhood and is much less common in adults. Our aim was to investigate the differences and similarities between adult and paediatric patients with IgAV/HSP. METHOD: We retrospectively evaluated the medical records of 35 adult and 159 paediatric (˂ 18 years old) patients with a clinical diagnosis of IgAV/HSP who were seen at the Departments of Rheumatology and Pediatric Rheumatology, Hacettepe University, Ankara, Turkey. The paediatric and adult patients were classified with IgAV/HSP according to the Ankara 2008 and American College of Rheumatology 1990 criteria, respectively. RESULTS: Upper respiratory tract infection was a common predisposing factor for both adults (34.3%) and children (21.4%). Creatinine and C-reactive protein were higher; and skin biopsy, hypertension, renal involvement, haematuria, proteinuria, and renal insufficiency at diagnosis were more frequent in adults than in children. Thrombocyte count was higher in children than in adults. Follow-up without treatment and complete recovery were more frequent in children, while persistent haematuria, chronic renal failure, relapse, and the use of corticosteroids/azathioprine were more frequent in adults. The only independent predictive factor for relapse was persistent haematuria. CONCLUSION: Various clinical and laboratory characteristics differ between children and adults with IgAV/HSP. Overall, IgAV/HSP has a self-limiting course in children but represents a more severe form of disease in adults, with more severe renal involvement. Persistent haematuria is a predictive factor for relapse.

Assessment of the HScore for reactive haemophagocytic syndrome in patients with rheumatic diseases.

OBJECTIVES: Reactive haemophagocytic syndrome (RHS) is a hyperinflammatory disorder often occurring in the background of several disorders such as infections, malignancies, and rheumatic diseases. Recently, a score known as the HScore was developed for the diagnosis of RHS. In the original study, most of the patients had underlying haematological malignancy or infection and the best cut-off value for the HScore was 169 (sensitivity 93%; specificity 86%). In this study we aimed to analyse the performance of the HScore in rheumatic disease-related RHS. METHOD: The patients with rheumatic disorders evaluated in the Departments of Rheumatology and Paediatric Rheumatology at Hacettepe University, Ankara, Turkey between 2002 and 2014 were reviewed retrospectively. The first group (n = 30) consisted of patients with RHS; the control group (n = 64) included patients with active rheumatic diseases without RHS. RESULTS: In the RHS group, 14 (46.7%) had adult-onset Still's disease (AOSD), 10 (33.3%) systemic juvenile idiopathic arthritis (SJIA), and six (20%) systemic lupus erythematosus (SLE). The control group (n = 64) consisted of 32 (50%) AOSD, 13 (20.3%) SJIA, and 19 (29.7%) SLE patients. Applying the HScore to the RHS patients, the best cut-off value was 190.5 with a sensitivity of 96.7% and specificity of 98.4%. When we excluded the patients from the control group who had not had bone marrow aspiration (n = 23), the same cut-off (190.5) performed best (sensitivity 96.7%; specificity 97.6%). Applying the 2004 haemophagocytic lymphohistiocytosis (HLH-2004) criteria gave a sensitivity of 56.6% and a specificity of 100% in the whole study group. CONCLUSIONS: In our study, a cut-off value for the HScore different from the original study performed better. Further studies are warranted to determine optimum cut-off values in different studies.

Aspirin resistance in systemic lupus erythematosus. A pilot study.

Systemic lupus erythematosus (SLE) patients are at increased risk of thrombosis and cardiovascular diseases. Aspirin is an effective treatment option for these patients. The aim of this study was to investigate the presence of aspirin resistance in SLE patients. We studied aspirin resistance in 33 SLE patients and nine healthy controls by using a Multiplate® impedance aggregometer (Dynabyte GmbH, Munich, Germany). Twenty-six SLE patients were on regular aspirin treatment. Aspirin resistance was found in five (19.2%) out of 26 patients who were on aspirin treatment. When the tests were repeated by adding acetylsalicylic acid in the medium, all of these patients became responsive to the aspirin. SLE disease activity, body mass index, smoking status, and the presence of anticardiolipin antibodies or positive lupus anticoagulant test results were no different in patients with or without aspirin resistance. (p>0.05 for all). Our results suggest that there may be a considerable number of SLE patients with aspirin resistance.

Infliximab, a TNF-α antagonist treatment in patients with ankylosing spondylitis: the impact on depression, anxiety and quality of life level.

The objective of this study was to assess the effect of infliximab on depression, anxiety and quality of life in patients with active ankylosing spondylitis (AS). In this 6-week longitudinal study, 16 patients with AS were assessed. Active disease as defined by BASDAI ≥4.0 was sought for inclusion. Infliximab was administered 5 mg/kg at 0, 2 weeks and 6 weeks. Collected data included age, sex and date of onset of rheumatologic disease. Activity of disease was measured using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Biological activity was evaluated with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). ESR and CRP were assessed at baseline and day 42. The Hospital Anxiety and Depression scale (HADS), Beck Depression Inventory (BDI) and 36-item Short Form Health Survey (SF-36) were used to evaluate anxiety, depression and quality of life. BASDAI, SF-36, HADS and BDE were assessed prior to the initial infliximab dose and at 2nd, 14th and 42nd day. Seven (43.8%) AS patients had depression scores above the cut off value for both the HADS depression (HADS-D) and BDI and 4 (25 %) had high HADS anxiety scores at baseline. Significant time effect for BDI and HADS-D scores were observed. Although significantly lower BDI scores were found after first, second and third infusions of infliximab, compared to initial score, the significant decrease in HADS-D appeared after second and third infusions. A significant time effect for HADS-anxiety scores were found as well. All of the subscales of SF-36 improved significantly during the course, with an exception of role emotional, for which the difference approached to the significance. The change in BASDAI scores and CRP and ESR, in the treatment process, were not correlated with the change in depression and anxiety scores. Infliximab which is an anti-TNF-α drug, may be effective in the treatment of depression accompanying AS. Possible implications for the treatment of major depressive disorder were discussed, as well.

Endothelial nitric oxide gene polymorphism and risk of systemic sclerosis: predisposition effect of T-786C promoter and protective effect of 27 bp repeats in Intron 4.

OBJECTIVES: An impaired availability of nitric oxide (NO), related to polymorphisms in endothelial nitric oxide synthase (eNOS) gene, may influence the microvasculature in systemic Sclerosis (SSc). Three potential eNOS gene polymorphisms [tandem 27-bp repeats (VNTR) in intron 4, T786C in promoter region and G894T in exon 7] were investigated to affect the susceptibility to and the clinical course of SSc. METHODS: Fifty-nine patients with SSc (mean age 47,1+/-12,1 years) and 83 control subjects (mean age 41,1+/-12,8 years) were studied. Genotypes were determined through PCR with or without RFLP. RESULTS: Genotype distribution was significantly different between SSc patients and controls for intron 4aa (alleles for four repeats), genotype frequency being 3.4% and 17.1%, respectively (odds ratio for dominant effect, 0.35; 95% CI, 0.17 to 0.78; p=0.004). The CC genotype of the promoter was significantly high in frequency in the SSc patients (16.9%) compared to controls (7.3%) (odds ratio for dominant effect, 2.26; 95% CI: 1.14 to 4.48; p=0.020). CONCLUSIONS: Intron 4 aa genotype of eNOS gene is protective and homozygosity (CC) of T-786C promoter region is a risk factor for SSc in Turkish population. Our results highlight a possible mechanism by which a potential reduced availability of NO, related to VNTR in intron 4 and T-786C promoter polymorphism, may influence the predisposition to SSc.

Takayasu's arteritis in Turkey - clinical and angiographic features of 248 patients.

OBJECTIVE: Takayasu's arteritis (TA) is a chronic, inflammatory vasculitis affecting the aorta and its major branches. Although it is more prevalent in Far-East Asia, the distribution of the disease is worldwide with different vascular involvement patterns and clinical manifestations. The objective of this study was to evaluate the demographic, clinical, angiographic and prognostic features of TA patients in Turkey. METHODS: Clinical and angiographic findings of 248 TA patients (228 female, 27 male) followed at 15 Rheumatology Centers were prospectively evaluated according to a predefined protocol. RESULTS: The mean age was 40.1 years (30.2 years at the clinical onset). Clinical manifestations included constitutional symptoms in 66%, absent or diminished pulses in 88%, bruits in 77%, extremity pain in 69%, claudication in 48%, hypertension in 43% and cerebrovascular accidents (CVA) in 18% of the patients. Renal artery stenosis, aortic regurgitation and pulmonary hypertension were present in 26%, 33% and 12%, respectively. According to the new angiographic classification, type V (50.8%) and Type I (32%) were the most frequent types of involvement. Corticosteroids were the main treatment in 93% of the patients alone (9%) or in combination with immunosuppressive agents (84%). Most frequently preferred immunosuppressive agents were methotrexate (63%), azathioprine (22%) and cyclophosphamide (13%). Remission was observed at least once in 94% of the patients and sustained remission in 71% during follow-up. CONCLUSION: The demographical, clinical and angiographic findings of TA patients in our series were similar to those reported from Japan, Brazil and Colombia. Combination therapies with immunosuppressive agents were the preferred choice of treatment in Turkey.

PTPN22 gene polymorphism in Takayasu's arteritis.

OBJECTIVE: Takayasu's arteritis (TA) is a chronic, rare granulomatous panarteritis of unknown aetiology involving mainly the aorta and its major branches. In this study, genetic susceptibility to TA has been investigated by screening the functional single nucleotide polymorphism (SNP) of PTPN22 gene encoding the lymphoid-specific protein tyrosine phosphatase. METHODS: Totally, 181 patients with TA and 177 healthy controls are genotyped by PCR-RFLP method for the SNP rs2476601 (A/G) of PTPN22 gene. Polymorphic region was amplified by PCR and digested with Xcm I enzyme. RESULTS: Detected frequencies of heterozygous genotype (AG) were 5.1% (9/177) in control group and 3.8% (7/181) in TA group (P = 0.61, odds ratio: 0.75, 95% CI: 0.3, 2.0). No association with angiographic type, vascular involvement or prognosis of TA was observed either. CONCLUSION: The distribution of PTPN22 polymorphism did not reveal any association with TA in Turkey.

Plasma and platelet serotonin levels in familial Mediterranean fever.

OBJECTIVE: Familial Mediterranean fever (FMF) is the most common auto-inflammatory syndrome with exaggerated acute phase and inflammatory response. After revealing the MEFV gene mutation with the finally disturbed end product pyrin, some of the mechanisms were explained. However it is still unknown what triggers or ends these periodical attacks. Moreover, the treatment of up to 30% of the patients, that are resistant to colchicine is still a problem. In this study we investigated the role of serotonin in colchicine-resistant FMF patients. METHODS: Twenty-four FMF patients (male/female: 15/9) and 32 age- and sex-matched healthy controls (male/female: 17/15) were included into the study. Patients were subdivided into two groups. Thirteen had FMF attacks despite regular colchicine (colchicine-resistant group), other 11 had disease under control with colchicine for at least 6-months. Sampling was done both during the attack and ten days after its cessation. Plasma and platelet serotonin levels and acute phase reactants were studied in patients and controls. RESULTS: Colchicine-resistant patients had plasma serotonin (5-HT) levels of 7.85 +/- 1.0 nmol/l during acute attacks which significantly reduced to the levels of 6.3 +/- 0.6 nmol/l (p < 0.001), after 10 days of acute attacks and these levels were significantly lower than those of attack-free patients' and controls' (10.7 +/- 0.2 nmol/l and 10.1 +/- 0.3 nmol/l, respectively). Platelet 5-HT level was 6.4 +/- 0.3 nmol/10(9) platelets during acute attack, and this level was increased to 9.8 +/- 0.5 nmol/10(9) platelets on the 2(nd) sampling, 10 days after the cessation of the acute attack (p < 0.001). They were both significantly higher than those of attack-free FMF patients (5.9 +/- 0.1 nmol/10(9) platelets) and healthy controls (5.7 +/- 0.3 nmol/10(9) platelets). There was a negative correlation between plasma and platelet 5-HT levels (r=-0.77, p < 0.001). CONCLUSION: Changes in plasma and platelet 5-HT levels may be related to the disturbances in 5-HT transport mechanisms or may also be attributed to the potential role of serotonin in the inflammatory cascade. Last but not least, serotonin may have a role in the pathogenesis of FMF.

Interferon-gamma assays for the diagnosis of tuberculosis infection before using tumour necrosis factor-alpha blockers.

OBJECTIVES: Patients who receive tumour necrosis factor-alpha (TNF-alpha) blockers are mostly immunosuppressed. A study was performed to investigate whether an interferon-gamma (IFN-gamma) assay could represent an alternative approach to the tuberculin skin test (TST) for the diagnosis of latent tuberculosis infection (LTBI) in these patients. DESIGN: We prospectively enrolled 106 individuals into the study in two groups. Group 1 consisted of 38 healthy individuals and Group 2 included 68 patients with chronic inflammatory diseases evaluated for LTBI before the use of TNF-alpha blockers. RESULTS: Of all participants, nine had indeterminate IFN-gamma test results. Agreement between the two tests was poor in both groups (kappa values respectively -0.54 and 0.18). In a total of 97 subjects, 10 (10.3%) were positive by the IFN-gamma test and 49 (50.5%) by TST. CONCLUSION: We found poor agreement between TST and the IFN-gamma test in our study. Our limited preliminary data should be accepted as a basis for designing future studies that will be helpful for physicians to decide whether the IFN-gamma test is more sensitive than the TST test in detecting LTBI before the use of TNF-alpha blockers.

Circulating thrombomodulin levels in familial Mediterranean fever.

Increments in circulating thrombomodulin levels reflect endothelial cell injury. Thrombomodulin can also be synthesized by several inflammatory cells including monocytes, neutrophils, and thrombomodulin itself can modulate the inflammatory response. In this study, we assessed circulating thrombomodulin concentrations in patients with familial Mediterranean fever (FMF). Twenty-five patients with FMF (F/M: 14/11) (mean age: 31.1 +/- 9.7 years) and 25 healthy controls (F/M: 13/12) (mean age: 34.6 +/- 7.0 years) were involved in the study. Thrombomodulin levels were measured by commercially available enzyme-linked immunosorbant assay (ELISA) (Immunoassay of thrombomodulin Diagnostica Stago, Asnieres-Sur-Seine, France). Twenty of the patients were in attack-free period and the remaining five had been during acute FMF attacks. Thrombomodulin levels were higher in the study group (20.9 +/- 12.1 ng/ml) than healthy controls (14.1 +/- 8.4 ng/ml) (p < 0.05). Circulating thrombomodulin levels were also higher in attack-free FMF patients (22.4 +/- 12.9 ng/ml) than controls. This study disclosed for the first time significantly higher increments in the circulating levels of thrombomodulin in FMF. This observation could be a consequence of injured endothelium and/or activated inflammatory cells.

Interleukin (IL)-12, IL-2, and IL-6 gene polymorphisms in Takayasu's arteritis from Turkey.

Takayasu's arteritis (TA) is a chronic arterial inflammation of unknown etiology involving mainly the aorta and its major branches. Genetic polymorphisms of cytokines are screened as susceptibility factors for TA in Turkey. A total of 94 patients with TA were investigated for the genetic polymorphisms of the interleukin genes IL12, IL2,and IL6 and were compared with 108 healthy control subjects using polymerase chain reaction-sequence-specific primer method. The frequencies of IL12B 1188 C allele (p = 0.03, OR = 1.7) and CC genotype (p = 0.007, OR = 3.7) were both higher in TA patients than in control subjects. TT genotype at IL2-330 (p = 0.006, OR = 2.4) and GG genotype at IL6-174 (p = 0.04, OR = 1.9) were more frequent in TA patients. Lower prevalence of GT genotype at IL2-330 (p = 0.005, OR = 0.4), CG genotype at IL6-174 (p = 0.001, OR = 0.4), and AG genotypes at IL6-598 (p = 0.01, OR = 0.4) were also detected. The polymorphism of IL-12 as well as IL-6 and IL-2 genes may contribute to susceptibility and pathogenesis of TA by altering cytokine production and inducing inflammation.

Extra-articular manifestations of rheumatoid arthritis: results of a university hospital of 526 patients in Turkey.

OBJECTIVE: Presence of extra-articular manifestations (EAM) in rheumatoid arthritis (RA) is associated with more severe disease and increased mortality. Prevalence of EAM may vary in different geographic areas and in different ethnic populations. In this study we investigated the frequency of EAM in 526 RA patients from a single university hospital in Turkey. METHODS: The hospital records of patients who had been diagnosed as RA in Hacettepe University Department of Rheumatology between the years 1988 and 2003 were retrospectively evaluated. There were 73 males and 453 females, and mean age of the patients was 48.0 +/- 12.3 years. The mean follow-up period was 4.8 +/- 4.1 years. Three hundred and fifty-nine patients were rheumatoid factor (RF) positive (68.3%). RESULTS: The overall frequency of EAM was 38.4% (202 patients). The most common EAM was rheumatoid nodules (18.1%). Sicca symptoms, pulmonary findings, Raynaud's phenomenon, livedo reticularis, carpal tunnel syndrome, vasculitis, amyloidosis, and Felty syndrome were present in 11.4%, 4.8%, 3%, 4.8%, 2.8%, 1.3%, 1.1%, and 0.3% of the patients, respectively. Overall EAM and rheumatoid nodules were significantly more common in RF positive patients than RF negative patients. The frequency of rheumatoid nodules was significantly higher in males than in females. CONCLUSION: The prevalence of EAM in Turkey is higher than East Asia and Africa, and lower than UK and North America. Excluding secondary Sjögren's syndrome, our results are similar to other Mediterranean populations like Italy.

Nosocomial meningitis in a university hospital between 1993 and 2002.

The aim of this study was to establish the relationship between nosocomial meningitis (NM) and surgical interventions, type of pathogens and other hospital infections (HIs). Fifty-one patients diagnosed with NM, according to the criteria of the Centers for Disease Control and Prevention, in the Neurosurgery Department of Ibn-i Sina Hospital of Ankara University between 1993 and 2002 were evaluated retrospectively. All individuals with NM were hospitalized in the intensive care unit. Third-generation cephalosporins were used for surgical prophylaxis and broad-spectrum antibiotics were used for treatment. NM occurred in 0.34% of all admissions and accounted for 0.53% of all HIs. Fourteen cases (28%) had at least one concurrent HI, mainly originating from surgical wounds and related secondary bacteraemia. Four cases had NM following surgical site infection with the same causative agent and three cases had bacteraemia. All the individuals had surgical interventions and 26 (51%) had operations concerning ventriculoperitoneal shunt. A positive microbiological cause was found in the cerebrospinal fluid of 49 patients, with 16 cases having a polymicrobial cause. Of all 67 micro-organisms isolated, 41 (61%) were Gram-negative bacilli, 23 (34%) were Gram-positive cocci and the remaining three (5%) were Candida spp. Staphylococci were the most common pathogens (30%), followed by non-fermentative Gram-negative bacilli (22%).

Serum interleukin 17 and interleukin 18 levels in familial Mediterranean fever.

OBJECTIVE: Familial Mediterranean fever (FMF) attacks are characterized by serosal inflammation rich in PMNL leukocytes and activation of a definite cytokine network. Moreover, there is sustained inflammation in attack-free FMF patients. Interleukin (IL)-17 and IL-18 are recently described proinflammatory cytokines, which can modulate certain neutrophil functions. In this study we measured serum levels of IL-17 and IL-18 in FMF patients. METHODS: The study groups comprised of 18 FMF patients in attack-free period (mean age: 30.2 +/- 9.5 years; male/female: 10/8), and 18 patients with an acute FMF attack (mean age: 25.4 +/- 4.9 years; male/female: 10/8). Twenty age-matched healthy subjects were included as a control group (male/female: 10/10). Levels of IL-17 and IL-18 were determined by commercial ELISA kits (Biosource International, USA). RESULTS: Serum IL-17 levels were 42.8 +/- 3.7, 42.7 +/- 3.2, and 39.9 +/- 2.3 pg/mL for FMF patients in attack-free period, FMF patients with acute attack, and healthy controls, respectively. Serum IL-18 levels were 878.8 +/- 315.0, 854.2 +/- 261.4, and 314.6 +/- 80.8 pg/mL for FMF patients in an attack-free period, FMF patients with acute attack, and healthy controls, respectively. Levels of both IL-17 and IL-18 were significantly higher in FMF patients with and without acute attack compared to control group (p < 0.05). Concentrations of those cytokines were comparable in FMF patients with acute attack and in attack-free period (p > 0.05). CONCLUSION: Our data suggest that IL-17 and IL-18 contribute to the cytokine network in the inflammatory cascade of FMF. However, their roles for the initiation of FMF attacks remain to be established.

The efficacy of continuous interferon alpha administration as an adjunctive agent to colchicine-resistant familial Mediterranean fever patients.

OBJECTIVE: About 10-20% of familial Mediterranean fever (FMF) patients are resistant to regular colchicine treatment and have painful recurrent attacks due to polyserositis. In clinical practice there is no alternative drug for such patients. In a previous pilot study on a small number of colchicine-resistant patients, interferon-alpha (IFN-alpha) was administered when painful attacks were about to occur. METHODS: In this study we gave IFN-alpha continuously to 8 colchicine-resistant FMF patients in a schedule while the colchicine therapy had been continued. All those patients were complicated with vasculitis or arthritis or together during the FMF course. Those complications were treated with the other immunosuppressive drugs. While they were under intense immunosuppressive therapy, the abdominal and the other serosal attacks remained to continue. RESULTS: After the administration of IFN-alpha therapy only one out of eight patients had abdominal painful attacks in twice, and one patient had arthritis in knees and ankles, the others responded well. Observed side effects were generally mild and acceptable. CONCLUSION: Continuous IFN administration in addition to the regular colchicine treatment may be useful for the colchicine-resistant attacks in FMF patients.

The contribution of underlying systemic rheumatic diseases to the mortality in patients admitted for intensive care: a matched cohort study.

OBJECTIVE: The aim of this study was to determine the outcome of patients with systemic rheumatic diseases admitted to our medical-intensive care unit (ICU) in comparison to the outcome of patients with non-rheumatic diseases in the same ICU. METHODS: The hospital files of 50 patients with systemic rheumatic diseases who were treated in the medical-ICU of Hacettepe University Hospital, Ankara between 1995 and 2001 were retrospectively evaluated. 50 patients without any underlying systemic rheumatic diseases admitted to the medical-ICU in the same time period and matched for age, gender and acute physiology and chronic health evaluation scores were included in the control group. ICU outcome was compared between the two groups. RESULTS: The acute physiology score of the study group was lower than that of the control group (13.4 +/- 5.7 [SD] vs. 17.3 +/- 7.2, p = 0.04). Moreover, the study group received more immunosuppressive treatment but less invasive procedures (i.e. mechanical ventilation and central venous catheterization). Mortality rates (56% vs. 54%, respectively, p = 0.5), lengths of stay in the ICU and in the hospital, the infection rates were similar between the rheumatic disease group and the control group. CONCLUSION: The presence of a systemic rheumatic disease seems to negatively affect the outcome in patients under intensive care.

The efficacy of oral cyclophosphamide plus prednisolone in early diffuse systemic sclerosis.

Pharmacological treatment of diffuse systemic sclerosis (SSc) directed at the tissue fibrosis has generally been ineffective. Many immunosuppressive drugs have been tried as therapy for SSc, regardless of the disease subtype and/or stage. The aim of this study was to show the efficacy and the toxicity of oral cyclophosphamide and prednisolone therapy on the prevention of fibrosis-based tissue damage in the early stages of the diffuse SSc. Twenty-seven patients with early diffuse SSc were treated with oral cyclophosphamide (1-2 mg/kg/day) plus oral prednisolone (40 mg/every other day) between the years 1995 and 1998. The results regarding the efficacy and toxicity of cyclophosphamide were compared with those of 22 early SSc patients who had been treated with oral D-penicillamine between 1992 and 1995. All the patients were evaluated using clinical and laboratory parameters every 6 months for 2 years. There was a significant improvement on the skin score, maximal oral opening, flexion index, predicted forced vital capacity (FVC) and carbon monoxide diffusing capacity (DLCO) in the cyclophosphamide group. The decrease in skin score in the cyclophosphamide group started earlier than in the D-penicillamine group. No life-threatening or irreversible adverse reaction was observed. This open study supports the use of oral cyclophosphamide plus prednisolone therapy to prevent fibrosis and its complications in the early stages of diffuse SSc.

Frequency of lymphadenopathy in rheumatoid arthritis and systemic lupus erythematosus.

This study aimed to assess the frequency of all palpable lymph nodes during active disease and remission in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Hospital records of 100 SLE patients, 100 RA patients, 100 spondyloarthropathy patients, and 150 osteoarthritis patients, treated in our rheumatology department, were evaluated retrospectively. Overall frequencies of enlarged lymph nodes in patients with active RA and SLE were 82% and 69%, respectively. Enlarged lymph nodes associated with RA were mostly located in the axillary region, and in SLE the nodes were smaller and lymphadenopathy was more generalized compared with RA. Palpable lymph nodes disappeared in the majority of patients during remission. Lymphadenopathy was significantly less frequent in patients treated with steroids before admission. Lymph node enlargement is an important physical finding associated with RA and SLE disease activity. Atypical locations and unusually large lymph nodes should raise clinical suspicion of another underlying disease.
