RESUMO

Objective To evaluate the extended follow-up of the CYCLOFA-LUNE trial, a randomized prospective trial comparing two sequential induction and maintenance treatment regimens for proliferative lupus nephritis based either on cyclophosphamide (CPH) or cyclosporine A (CyA). Patients and methods Data for kidney function and adverse events were collected by a cross-sectional survey for 38 of 40 patients initially randomized in the CYCLOFA-LUNE trial. Results The median follow-up time was 7.7 years (range 5.0-10.3). Rates of renal impairment and end-stage renal disease, adverse events (death, cardiovascular event, tumor, premature menopause) did not differ between the CPH and CyA group, nor did mean serum creatinine, 24 h proteinuria and SLICC damage score at last follow-up. Most patients in both groups were still treated with glucocorticoids, other immunosuppressant agents and blood pressure lowering drugs. Conclusion An immunosuppressive regimen based on CyA achieved similar clinical results to that based on CPH in the very long term.

RESUMO

Neuropsychiatric manifestations are present in 30-40% of patients with systemic lupus erythematosus (SLE). Recently, antibodies to aquaporin-4 (termed AQP4-Ab, or NMO-IgG), a water channel protein, were reported to be present in a subset of patients with SLE and neurological involvement. To evaluate the syndrome specificity and prevalence of serum NMO-IgG/anti-AQP4 antibodies in patients with neuropsychiatric systemic lupus erythematosus (NPSLE). Sera of 76 patients with SLE and neurological symptoms, 50 of whom met the ACR case definitions of NPSLE, were tested for AQP4-Ab in an indirect immunofluorescence assay employing HEK293 cells transfected with recombinant human AQP4. Only one of the examined sera was positive for NMO-IgG/AQP4-Ab. This patient suffered from TM, ranging over two vertebral segments on spinal MRI. None of the 75 NPSLE without TM was found to be seropositive for NMO-IgG/AQP4-Ab. NMO-IgG/AQP4-Ab in NPSLE were present only in a patient with TM and were not detectable in NPSLE patients with other neurological manifestations. Testing for NMO-IgG/AQP4-Ab positivity should be considered in patients presenting with SLE and TM. Non-longitudinally extensive lesions do no not exclude NMO-IgG/AQP4-Ab in patients presenting with SLE and TM.

RESUMO

Intravenous cyclophosphamide is considered to be the standard of care for the treatment of proliferative lupus nephritis. However, its use is limited by potentially severe toxic effects. Cyclosporine A has been suggested to be an efficient and safe treatment alternative to cyclophosphamide. Forty patients with clinically active proliferative lupus nephritis were randomly assigned to one of two sequential induction and maintenance treatment regimens based either on cyclophosphamide or Cyclosporine A. The primary outcomes were remission (defined as normal urinary sediment, proteinuria <0.3 g/24 h, and stable s-creatinine) and response to therapy (defined as stable s-creatinine, 50% reduction in proteinuria, and either normalization of urinary sediment or significant improvement in C3) at the end of induction and maintenance phase. Secondary outcomes were incidence of adverse events, and relapse-free survival. At the end of the induction phase, 24% of the 21 patients treated by cyclophosphamide achieved remission, and 52% achieved response, as compared with 26% and 43%, respectively of the 19 patients treated by the Cyclosporine A. At the end of the maintenance phase, 14% of patients in cyclophosphamide group, and 37% in Cyclosporine A group had remission, and 38% and 58% respectively response. Treatment with Cyclosporine A was associated with transient increase in blood pressure and reversible decrease in glomerular filtration rate. There was no significant difference in median relapse-free survival. In conclusion, Cyclosporine A was as effective as cyclophosphamide in the trial of sequential induction and maintenance treatment in patients with proliferative lupus nephritis and preserved renal function.(ClinicalTrials.gov identifier: NCT00976300)

RESUMO

OBJECTIVE: Systemic lupus erythematosus (SLE) is accompanied by severe oxidative stress. Bilirubin has been reported as a strong negative predictor of oxidative stress-mediated diseases, such as atherosclerosis. The objective of our study was to evaluate the association between serum bilirubin levels and SLE manifestation. METHODS: The study was performed with 259 SLE patients, diagnosed according to American Rheumatism Association (ARA) criteria. A subset of these patients, having normal hepatic function (n = 218, mean age 39.5 years), was studied in greater detail to eliminate the possible confounding effects of any underlying or drug-induced liver disease on the serum bilirubin levels. Age-matched healthy subjects (n = 180) served as the control group. A standard biochemical and immunological work-up was performed on all subjects. RESULTS: Compared to the controls, substantially lower levels of serum bilirubin were detected in SLE patients (p < 10⁻5); these were inversely correlated with disease activity and extent (p < 0.05). Furthermore, each 1 µmol/L decrease in serum bilirubin was associated with a 37% increase in the odds for a positive SLE status [odds ratio (OR) 1.37, 95% confidence interval (CI) 1.28-1.47, p < 10⁻5]. Simultaneously, the odds of unconjugated hyperbilirubinaemia (a phenotypic sign of Gilbert's syndrome) were more than four times lower in SLE patients (OR 0.235, 95% CI 0.072-0.764, p = 0.016). CONCLUSION: Low serum bilirubin represented a strong predictor of the manifestation of SLE symptoms. The most likely explanation for this finding is the increased consumption of bilirubin due to the severe oxidative stress accompanying SLE. Subjects with higher serum bilirubin levels, such as those with Gilbert's syndrome, might be protected from the development of SLE.

RESUMO

OBJECTIVE: The aim of our study was to determine the volume of pathological foci in the brain tissue of patients suffering from systemic lupus erythematosus (SLE) with or without neuropsychiatric manifestations (NP), and also to find out if that volume depends on the study subjects' data and clinical records. Magnetic resonance (MR) scans of patients with SLE and, in particular, signs of neuropsychiatric involvement, show pathological foci in the cerebral white matter. METHODS: A total of 53 SLE patients, 29 with signs of neuropsychiatric syndromes (NPSLE), 24 without, and 16 healthy controls underwent prospective volumetric magnetic resonance imaging in a flow attenuated inversion recovery (FLAIR) sequence. The disease activity was expressed in terms of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). RESULTS: All the patients in this study were found to have a larger volume of pathological foci in the brain tissue than the healthy controls. The NPSLE subgroup had a larger volume of pathological foci than the SLE patients without NP (p<0.001). The largest volume of such foci was found in the patients with a history of cerebrovascular disease (p<0.05). These were also noted for a correlation between the duration of the disease and the period of time elapsed from the onset of the first signs of neuropsychiatric lupus (p<0.01). Correlation with SLEDAI-rated disease activity was found statistically significant in all the patients (p<0.05) and in those with NPSLE at a level of p<0.01. CONCLUSION: We found that the lesion load was significantly larger in NPSLE than in SLE patients free from NP and controls. Our measurement revealed a positive correlation between the lesion load and SLEDAI in the whole SLE patients group, particularly in the subgroup with NP manifestation. In the future, longitudinal volumetry might conceivably facilitate the therapeutical effect rating.

RESUMO

OBJECTIVE: To evaluate the clinical status and radiographic progression in patients with rheumatoid arthritis (RA) being followed by the Czech National Registry of biological treatments. METHODS: Patients who failed at least two disease-modifying antirheumatic drugs and had high disease activity (DAS28 > 5.1) were treated with infliximab. Radiographic progression was measured with a modified version of the Sharp score (TSS) after 54 weeks of treatment. RESULTS: Ninety-nine patients with an average disease duration of 13.7 years were enrolled. The DAS28 dropped from 6.66 to 4.07 (p < 0.001). Before treatment the mean TSS was 90.1 and the mean estimated yearly disease progression was 8.56. After 54 weeks of infliximab, radiographic progression was 4.15 times slower than the estimated rate before treatment and 63 patients did not show any radiographic progression at all. In the remaining 36 patients, the progression rate slowed to 3.8 +/- 0.9 from the estimated TSS of 10.9 +/- 6.9 before the initiation of treatment (p = 0.011). CONCLUSION: Data derived from the Czech National Registry, which reflect general clinical practice, show a significant retardation of radiographic progression in patients treated with anti-TNF and the magnitude of the improvement seen is similar to results from clinical trials.

RESUMO

A case of a female patient suffering from Lyme arthritis (LA) without elevated antibody levels to Borrelia burgdorferi sensu lato is reported. Seronegative Lyme arthritis was diagnosed based on the classic clinical manifestations and DNA-detected Borrelia garinii in blood and synovial fluid of the patient, after all other possible causes of the disease had been ruled out. The disease was resistant to the first treatment with antibacterial agents. Six months after the therapy, arthritis still persisted and DNA of Borrelia garinii was repeatedly detected in the synovial fluid and the tissue of the patient. At the same time, antigens or parts of spirochaetes were detected by electron microscopy in the synovial fluid, the tissue and the blood of the patient. The patient was then repeatedly treated by antibiotics and synovectomy has been performed.

RESUMO

Our objective was to determine the effect of 1 year low-dose cyclosporine A (CSA) treatment on disease activity and renal involvement in systemic lupus erythematosus (SLE). Patients included in the pilot study had an active form of the disease as defined by the SLE Disease Activity Index (SLEDAI). Main organ involvement was represented by lupus nephritis classified in repeated renal biopsies. Eleven patients with SLE were enrolled in the study. In eight of them, previous therapy with cyclophosphamide or azathioprine had to be interrupted due to serious adverse reaction or low efficacy. Nine patients experienced clinical nephrotic syndrome, and two the nephritic syndrome. After 12 months of CSA treatment, the mean SLEDAI score had decreased significantly from 26.18 to 4.00 (P < 0.01). Similarly, the titre of antinuclear and anti-dsDNA antibodies had dropped significantly (P < 0.01). Proteinuria decreased rapidly from 9.10 to 1.70 g/24 h (P < 0.001). According to the WHO classification of renal biopsies, three patients had their class altered from IV to III in response to CSA treatment and five patients had changed the status from the high severity grade to the mild. The adverse reactions included hypertension (45%), gingival hyperplasia (18%) and hirsutism (9%). No significant increase in serum creatinine or any CSA related toxic changes were found in renal biopsies. The favourable response observed in patients with active SLE and with major renal involvement strongly suggests that low-dose CSA is a potent drug as much for the reduction of the disease activity as for lupus nephropathy treatment.
