To determine the outcome and identify risk factors for evolution into systemic lupus erythematosus (SLE) in a population of incomplete lupus erythematosus (ILE) patients, we studied the clinical and serologic manifestations in a cohort of 87 ILE patients. ILE patients had at least one but less than four of the American College of Rheumatology (ACR) classification criteria of SLE and did not present distinctive clinical features or meet classification criteria of other connective tissue diseases. The patients that remained with ILE were compared with patients that evolved into SLE and with a cohort of 94 SLE patients. The mean disease duration and follow up of ILE patients were 4.4 +/- 4.1 and 2.2 +/- 2.4 years respectively. Eight patients evolved into SLE, but none presented major organ damage. At baseline, patients that remained with ILE were less likely to have photosensitivity, elevated anti-dsDNA and decreased C3 complement than patients that evolved into SLE. At the end of the study, malar rash and oral ulcerations were also less frequent in the ILE group. Compared with all SLE cases, ILE patients were less likely to have photosensitivity, malar rash, oral ulcers, Raynaud's phenomenon, arthritis, low C3, low C4, positive anti-dsDNA, anti-Sm, anti-RNP, anti-Ro and anti-La antibodies at baseline. Hazard analyses showed that malar rash, oral ulcers, elevated anti-dsDNA and decreased C4 were associated with SLE occurrence. In conclusion, this study suggests that ILE represents a mild spectrum of lupus in which mucocutaneous and serological abnormalities are associated with progression into SLE.

The aim of this study was to determine the factors associated with metabolic syndrome in patients with systemic lupus erythematosus from Puerto Rico. A total of 204 patients with systemic lupus erythematosus (per the American College of Rheumatology classification criteria) were evaluated. Metabolic syndrome was assessed using the American Heart Association and the National Heart, Lung, and Blood Institute classification. Socioeconomic-demographic parameters, health-related behaviours, clinical manifestations, autoantibodies, pharmacological treatments, disease activity (per the Systemic Lupus Activity Measure-Revised), and damage accrual (per the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index) were determined at study visit. Factors associated with metabolic syndrome were examined by univariable analyses and multivariable logistic regression models. A total of 196 (96.2%) were women. The mean age at study visit was 43.6 ± 13.0 years, and the mean disease duration was 8.7 ± 7.7 years. Seventyeight patients (38.2%) had metabolic syndrome. In the multivariable analysis, age (odds ratio [OR] = 1.05; 95% confidence interval [CI] 1.02-1.09), government health insurance (OR = 2.06; 95% CI 1.07-4.22), exercise (OR = 0.33; 95% CI 0.14-0.92), thrombocytopenia (OR = 4.19; 95% CI 1.54-11.37), erythrocyte sedimentation rate (OR = 1.64; 95% CI 1.03-2.63), disease activity (OR = 1.14; 95% CI 1.00-1.30), and prednisone >10 mg/day (OR = 3.69; 95% CI 1.22-11.11) were associated with metabolic syndrome. In conclusion, older age, low socioeconomic status, lack of exercise, thrombocytopenia, increased erythrocyte sedimentation rate, higher disease activity, and prednisone >10 mg/day were independently associated with metabolic syndrome in patients with systemic lupus erythematosus from Puerto Rico.

To gain a better understanding of systemic lupus erythematosus (SLE) in Puerto Ricans we studied the clinical and serologic manifestations in a cohort of 134 patients. The female to male ratio was 18:1. Mean age at diagnosis was 32 +/- 12 y. The mean duration of disease and follow-up were 7.4 +/- 6.0 and 5.8 +/- 6.0 years respectively. Mortality was 3%. Photosensitivity (76.9%) and malar rash (71.9%) were the most common clinical manifestations. Arthritis was observed in 67.5% of patients. Anemia was seen in 67.2% of patients, but only 12.7% had autoimmune hemolytic anemia. Leukopenia (41.8%) and lymphopenia (64.9%) were also common. Serositis was observed in only 28%. Severe kidney damage such as nephrotic syndrome (14.2%) or renal failure (4%) was infrequent. Cardiovascular (12.7%) and neurologic (9.0%) manifestations were also uncommon. Antinuclear antibodies (ANA) were detected in 93.3%, anti-dsDNA antibodies in 54.5%, anti-Ro antibodies in 30.1% and anti-La antibodies in 14.2%. Low C3 and low C4 were observed in 38.3% and 35.7% respectively. This study suggests that Puerto Ricans with SLE present a mild form of disease predominantly manifested by cutaneous, musculoskeletal and hematologic involvement, but low prevalence of major organ damage and low mortality.

There are few cases of Guillain-Barré syndrome (GBS), particularly of atypical variants, occurring in association with systemic lupus erythematous (SLE). Reports addressing a specific therapy thus remain almost anecdotal. It is therefore challenging to determine the treatment that is best suited for this subset of patients, especially if initial conventional therapy for GBS fails. We present two cases of GBS-like acute axonal neuropathies, one with acute motor axonal neuropathy (AMAN), and another with acute motor sensory axonal neuropathy (AMSAN), presenting early in the course of SLE. The first case failed to respond to therapy with intravenous immunoglobulins (IVIG) and plasmapheresis, but achieved a favorable outcome when high-dose glucocorticoids along with low-dose intravenous (IV) cyclophosphamide pulses were given. The second case responded favorably to high-dose glucocorticoids, IVIG, and low-dose IV cyclophosphamide pulses. Both patients have remained in clinical remission and without neurologic sequelae after 10 and three years of follow-up, respectively.

Objective The objective of this report is to determine the impact of remission and low disease activity state (LDAS) on damage accrual and mortality in systemic lupus erythematosus (SLE) patients. Patients and methods Visits from the Lupus in Minority populations: Nature vs. Nurture (LUMINA) cohort were categorized into remission (Systemic Lupus Activity Measure (SLAM) score = 0 and prednisone ≤ 5 mg/day and no immunosuppressants), LDAS ((not on remission), SLAM score ≤ 3, prednisone ≤ 7.5 mg/day, no immunosuppressants), or neither: active. Remission and LDAS visits were combined because of the relatively small number of remission visits. Their impact on damage accrual and mortality were examined by Poisson and logistic multivariable regressions adjusting for variables known to affect these outcomes. Results A total of 3879 visits for 558 patients (28% Caucasian, 37% African descent, 35% Hispanic) were studied. These visits corresponded to 71 in remission, 585 in LDAS, and 3223 active. The longer the percentage of time the patients were in remission/LDAS, the less damage accrual observed (rate ratio 0.1773 (95% confidence interval (CI) 0.1216 to 0.2584) p < 0.0001). A trend was observed in terms of mortality although statistical significance was not reached (odds ratio 0.303 (95% CI 0.063 to 1.456), p = 0.1360). Conclusions The longer the patient's state on Remission/LDAS, the less damage accrual that occurs. The protective effect on mortality was not statistically significant.
