Our purpose was to examine prospectively the relationship between systemic hypertension and vascular events in patients with SLE. SLE patients followed in the University of Toronto Lupus Clinic presenting between 1980 and 1988 and within one year of their diagnosis of SLE were identified. Standard definitions were used for hypertension and for all vascular events (MI, angina, CVA, PVD). The presence of traditional CAD risk factors, along with disease- and therapy-related risk factors for the development of vascular disease, were compared in the hypertensive and normotensive group. A multivariate logistic regression was performed to determine the best predictor of a vascular event. One hundred and fifty patients were identified in our inception cohort [75 hypertensive (50%) and 75 (50%) normotensive]. Seventeen hypertensive patients (22.7%) had at least one vascular event as compared to six (8.0%) normotensive patients (p = 0.022). The vascular events included 7 with CAD, 5 with CVA, and 5 with PVD in the hypertensive group while in the normotensive group 3 patients developed CAD, 2 CVA and 1 PVD. Fifteen deaths were recorded in the hypertensive group as compared to eight deaths in the non-hypertensive groups (P = 0.09). The groups were comparable with respect to associated risk factors, except for higher frequency of hypercholesterolemia (P = 0.003), azotemia (P = 0.001) and corticosteroid use (P = 0.038) in the hypertension group. In a multivariate analysis the best predictor of a vascular event was hypercholesterolemia (OR 6.9, 95% CI 2.4-24.8, P < 0.001). We conclude that systemic hypertension is associated with an increased frequency of vascular events in SLE. This is best explained by its association with hypercholesterolemia.

The first case of a cutaneous cryptococcosis associated with systemic erythematous lupus (SLE) diagnosed in our Mycology Reference Centre is presented: a 24-year-old female patient diagnosed with SLE, nephrotic syndrome, arterial hypertension, renal insufficiency due to glomerulonephritis type IV and cellulitis in the right thigh and gluteus. Cryptococcus neoformans was isolated by cutaneous biopsy and haemoculture. Cryptococcal antigen was detected in serum by the latex agglutination test. As the patient did not respond to fluconazol intravenous treatment, amphotericin B administration was performed. She died of acute renal insufficiency.

Among connective tissue diseases, systemic lupus erythematosus is the illness that is most concerned by hormonal life events. The sex ratio is 9/1, and symptoms begin mostly during the third decade, sometimes during birth pill contraception or during pregnancy. As soon as systemic lupus is under control of an efficient treatment, pregnancy is no longer contra-indicated. A medical multidisciplinary surveillance is required. Complicated pregnancy concerns mother and baby. Lupus flares are more frequent during the second and third trimesters as well as during the post-partum period. Usually the intensity is moderate. Severe flares concern patients with renal involvement, hypertension and renal insufficiency and are mostly seen in patients with unplanified pregnancy and yet with still active lupus. Foetal death occurs in 10-30% of the cases, depending on the lupus activity and severity (renal lupus). Prematurity remains an important cause of morbidity (30% of live births). Foetal deaths and prematurity are even more frequent if the patient has an antiphospholipid syndrome. Neonatal cutaneous lupus and auriculo-ventricular congenital heart block is infrequent (1% of SLE patients with anti-Ro/SSA antibodies). Among other connective tissue diseases, polymyositis has a very severe obstetrical prognosis for both mother and foetus. Among primary vasculitis, polyarteritis nodosa, as found during pregnancy, can herald a very bad prognosis.

The Systemic Lupus International Collaborating Clinics/American College of Rheumatology (ACR) Damage Index (SDI) is an accepted instrument to ascertain damage. It has been shown to vary among different SLE populations. The aim of this study was to assess SDI score, pattern and factors related to damage in Brazilian SLE outpatients. The SDI was obtained in 105 patients with a median age of 41 (5-95%, 19-61.7) years and a median SLE duration of 127 (17.6-345.9) months. Patients had a median SDI of 2 (0-8) and 81.9% had some damage (SDI > 0). Damage was associated with a higher number of ACR criteria for SLE in multivariate analysis (OR = 2.32, 95%CI = 1.23-4.37, P = 0.009). Antiphospholipid syndrome (APS) (OR = 9.82, 95%CI = 2.74-35.23, P < 0.001), methylprednisolone pulses (OR = 3.91, 95%CI = 1.19-12.81, P = 0.024), age (OR = 1.70, 95%CI = 1.02-1.13, P = 0.011) and prednisone use duration (OR = 1.01, 95%CI = 1.002-1.02, P = 0.020) were related to severe damage (SDI > or = 4). Hypertension was associated with renal, cardiac and atherosclerotic damage, as cyclophosphamide pulses were with premature menopause. In conclusion, damage was very frequent in Brazilian SLE patients, mainly due to skin involvement, compared to other SLE populations. The presence of APS was the major independent contributor to the development of severe damage. Arterial hypertension was identified as a common risk factor for renal, cardiac and atherosclerotic damage.

Systemic lupus erythematosus is a hormone-dependent disorder predominantly affecting young women in whom changes in hormonal activity affect the course of the disease. More specifically, pregnancy is associated in 50 to 60% of cases with a clinical flare manifesting as renal or hematological symptoms, usually during the second or third trimester but occasionally in the postpartal period. Patients should be strongly advised to start a pregnancy only if their disease has been stable for at least 6 months, and they should be informed of the few contraindications. Severe flares are uncommon (10%) and the risk of maternal death is now 2 to 3%. The risk of the fetus remains high, however. Thus, fetal loss is common, particularly in patients with a lupus anticoagulant, renal failure, or arterial hypertension. Preterm birth occurs in 25% to 50% of cases and intrauterine growth retardation in 30%. Neonatal lupus with or without congenital heart block is exceedingly rare, being seen in the 1% of SLE women who have anti-SSA (Ro) and/or SSB (La) antibodies. To ensure a favorable outcome for both the mother and the child, the pregnancy should be planned, started during a period of disease stability, monitored closely (physical examination, laboratory tests, and Doppler ultrasound), and treated as needed (with antimalarial therapy throughout the pregnancy). Even with these precautions, however, preterm birth remains common.

1. The numbers of CGN patients have decreased, with a corresponding increase in transplants into IDDM. HTN and MHT have also increased in recent years. 2. Waiting time on dialysis has increased, with an increase in patient age. 3. Transfusions have decreased for all diseases, although less so for SLE. 4. Disease recurrence was highest in FGS, IgA, SLE and CGN. The incidence of recurrence has decreased in recent years. 5. Tacrolimus-MMF and Neoral-MMF were superior to CsA-AZ for all diseases with respect to 5-year graft survival. 6. Systemic diseases such as SLE and IDDM had lower graft survival rates than IgA, PC and ALP. Exclusion of deaths made functional graft survival of all diseases quite similar. 7. Blacks had lower graft survival rates than Whites, Hispanics, and Asians for all diseases. 8. SPK had higher graft survivals than KA in Blacks and Whites. 9. PC patients with HLA-DR1 had a statistically significant higher graft survival than those without DR1 in Whites and Hispanics. 10. IDDM patients with HLA-DR4 had a statistically significantly higher graft survival rates than those without DR4 in Blacks, Whites, Hispanics, and Asians. 11. PC, IgA, and ALP patients had a lower incidence of rejection before discharge than other patients. HTN and IDDM patients had the highest rate of first day non-function and need for dialysis. 12. Need for dialysis and rejection before discharge led to 20 percentage points lower 5-year graft survival compared with those patients who were free of these complications. 13. First day anuria led to 10 percentage point lower 5-year graft survival compared with those with first day diuresis.

Genetic polymorphisms of the renin-angiotensin system (RAS) has been associated with cardiovascular events and the progression of nephropathy in several diseases. The objective of this study was to evaluate a possible association of the genetic polymorphisms of RAS with the development and/or progression of lupus nephritis in a Brazilian population. Seventy-five SLE patients with lupus nephropathy (LN group) were compared to 72 SLE patients without LN (SLE group) and 65 healthy individuals (CONTROL group), of sex and ethnic matched, in a Brazilian population sample. Mean global follow-up was 9 +/- 6 years for lupus without nephropathy and 11 +/- 7 years for lupus nephropathy. Following the extraction of genomic DNA from the leukocytes in the peripheral blood, angiotensin converting enzyme (ACE I/D), angiotensinogen (AGT M(235)T) and angiotensin II type 1 receptor (AGTR1 A(1166)C) genotypes were determined by the polymerase chain reaction. No significant difference of ACE, AGT and AGTR1 genotypes distribution between groups was observed in this study. There was no significant association between the variables of the RAS genotypes and the presence of hypertension in SLE. However, an increased frequency ofDD genotype (ACE I/D) was observed in SLE patients with LN who progressed to CRF compared to healthy controls (DD 60%, DI 26.7%, II 13.3% versus 27.7%, 60% and 12.3%, respectively; chi2 = 6.299, P = 0.0429). In the population studied, there was no influence of the RAS genetic polymorphisms in the development of lupus nephropathy, but the progression to CRF was associated with ACE DD polymorphism.

Inflammatory rheumatic diseases are associated with a substantial increase in accelerated atherosclerosis, with complex interactions between traditional and disease-related risk factors. Therefore, cardiovascular risk reduction should be considered as integral to the control of disease activity in the care plans of patients with RA, SLE and, arguably any chronic inflammatory disease. Shared care structures, already established for the monitoring of DMARDs, could be adapted to communicate and monitor cardiovascular risk reduction objectives. We review the evidence for the efficacy of a range of therapeutic strategies, the majority of which impact on both disease activity and cardiovascular risk. The algorithm proposed here attempts to distil the latest advice from specialist panels at the National Cholesterol Education Program and the British Hypertension Society, as well as incorporating the existing data on SLE and RA patients. The algorithm is structured to minimize clinic time and resources necessary to stratify patients into groups for ROUTINE, SUBSTANTIAL or INTENSIVE risk management; the associated table summarizes optimal therapeutic objectives in each of these groups. The implication of this algorithm is that management of cardiovascular risk should be much more aggressive than is currently the norm in patients with chronic inflammatory diseases, such as RA and SLE. Long-term studies of such interventions are needed to further clarify the benefits of intensive cardiovascular risk management in these patients.

The objective of the study was to evaluate the influence of the male gender in the clinical presentation and outcome of systemic lupus erythematosus in a prospective inception cohort of Latin-American patients. Of the 1214 SLE patients included in the GLADEL cohort, 123 were male. Demographic characteristics as well as clinical manifestations, laboratory profile, activity and damage scores were evaluated at onset and during the course of the disease and compared with female patients. The median age at onset of the male patients was 27 and that at diagnosis 29.2 years. Delay to diagnosis was shorter in males (134 versus 185 days, P = 0.01). At onset, men more frequently showed fever (42.3 versus 27.0%, P = 0.001) and weight loss (23.6 versus 11.8%, P = 0.001). During disease course the incident of symptoms was: fever, 67.8 versus 55.6%, P = 0.012; weight loss, 47.2 versus 24.3%, P = 0.001; arterial hypertension, 37.4 versus 25.8%, P = 0.007; renal disease (persistent proteinuria and/or cellular casts), 58.5 versus 44.6%, P = 0.004); and hemolytic anemia, 19.5 versus 10.9%, P = 0.008. The laboratory results showed that: men more frequently had IgG anticardiolipin antibodies (68.2 versus 49%, P = 0.02) and low C3 (61.3 versus 48.1%, P = 0.03); 5/123 men died (4%) compared with 29/1091 women (2.7%). In conclusion, 10% of GLADEL's cohort patients were male. They showed a distinctive profile with shorter delay to diagnosis, higher incidence of fever, weight loss, arterial hypertension, renal disease, hemolytic anemia, IgG anticardiolipin antibodies and low C3. Although not statistically significant, mortality was higher in men.

The objective of this study is to evaluate the efficacy, toxicity, and long-term outcome of low-dose IV cyclophosphamid therapy with repeated frequent intervals in combination with oral and IV methylprednisolone in patients with SLE nephritis. In this study, 113 patients diagnosed as having SLE and glomerulonephritis were assessed in between 1993 and 2002, with a median follow-up of 44.1+/-41.2 months. The patients were treated with 500 mg IV cyclophosphamide and 1 g IV methylprednisolone together with 60 mg/alternate-day oral methylprednisolone in a given schedule. The clinical and laboratory data were evaluated. There were significant improvements in the clinical and the laboratory parameters. Six patients died shortly after being hospitalized due to the disease activity itself. Eight patients were excluded from the study because of low compliance. The renal functions of the patients remained stable throughout the therapy; only 16/99 patients needed one or two additional pulses. Temporary leukopenia developed in 18/99 patients and diminished with the suspension or prolongation of the IV cyclophosphamide administration. Gastrointestinal side effects, which needed extra medication, developed in 20 patients. Hematuria was observed in 6/99 patients. Menstrual abnormalities were seen in 7/99 patients. No serious infections due to immunosuppression were observed with the given regimen. Hypertension was observed in 13 patients (minimum of 140/90 mmHg, maximum of 190/110 mmHg) and controlled with angiotensine-converting enzyme inhibitors. Mild central obesity was observed in 15 of the patients. Leimyosarcoma was observed in one patient who died during the follow-up period. Therapy starting with the weekly low-dose IV cyclophosphamide to induce remission together with IV and oral steroids, followed by prolonged intervals with the same doses for 2 years, appears to be useful in preserving renal function without major side effects in patients with lupus nephritis, in comparison to other studies.
