Predictive Factors of the Use of Rituximab and Belimumab in Spanish Lupus Patients.

Objectives: To analyze the characteristics and the predictive factors of the use of rituximab and belimumab in daily practice in patients from the inception cohort Registro Español de Lupus (RELES). Material and methods: The study included 518 patients. We considered patients treated with biologics who received at least one dose of rituximab or belimumab, and possible indications of those manifestations registered at the same time or in the previous 2 months of the start of the therapy. Results: In our cohort, 37 (7%) patients received at least one biological treatment. Rituximab was prescribed in 26 patients and belimumab in 11. Rituximab was mainly prescribed for hemolytic anemia or thrombocytopenia (11 patients, 42%), lupus nephritis and neuropsychiatric lupus (5 patients each, 19%). Belimumab was mostly used for arthritis (8 patients, 73%). In the univariate analysis, the predictive factors at diagnosis for the use of biologic therapy were younger age (p = 0.022), a higher SLEDAI (p = 0.001) and the presence of psychosis (p = 0.011), organic mental syndrome (SOCA) (p = 0.006), hemolytic anemia (p = 0.001), or thrombocytopenia (p = 0.01). In the multivariant model, only younger age, psychosis, and hemolytic anemia were independent predictors of the use of biologics. Conclusions: Rituximab is usually given to patients with hematological, neuropsychiatric and renal involvement and belimumab for arthritis. Psychosis, hemolytic anemia and age at the diagnosis of lupus were independent predictive factors of the use of biological agents. Their global effects are beneficial, with a significant reduction in SLE activity and a low rate of side effects.

Pragmatic, open-label, single-center, randomized, phase II clinical trial to evaluate the efficacy and safety of methylprednisolone pulses and tacrolimus in patients with severe pneumonia secondary to COVID-19: The TACROVID trial protocol.

INTRODUCTION: Some COVID-19 patients evolve to severe lung injury and systemic hyperinflammatory syndrome triggered by both the coronavirus infection and the subsequent host-immune response. Accordingly, the use of immunomodulatory agents has been suggested but still remains controversial. Our working hypothesis is that methylprednisolone pulses and tacrolimus may be an effective and safety drug combination for treating severe COVID-19 patients. METHODS: and analysis: TACROVID is a randomized, open-label, single-center, phase II trial to evaluate the efficacy and safety of methylprednisolone pulses and tacrolimus plus standard of care (SoC) versus SoC alone, in patients at advanced stage of COVID-19 disease with lung injury and systemic hyperinflammatory response. Patients are randomly assigned (1:1) to one of two arms (42 patients in each group). The primary aim is to assess the time to clinical stability after initiating randomization. Clinical stability is defined as body temperature ≤37.5 °C, and PaO2/FiO2 > 400 and/or SatO2/FiO2 > 300, and respiratory rate ≤24 rpm; for 48 consecutive hours. DISCUSSION: Methylprednisolone and tacrolimus might be beneficial to treat those COVID-19 patients progressing into severe pulmonary failure and systemic hyperinflammatory syndrome. The rationale for its use is the fast effect of methylprednisolone pulses and the ability of tacrolimus to inhibit both the CoV-2 replication and the secondary cytokine storm. Interestingly, both drugs are low-cost and can be manufactured on a large scale; thus, if effective and safe, a large number of patients could be treated in developed and developing countries.

Clinical characteristics during diagnosis of a prospective cohort of patients with systemic lupus erythematosus treated in Spanish Departments of Internal Medicine: The RELES study. / Características clínicas al diagnóstico de una cohorte prospectiva de pacientes con lupus eritematoso sistémico atendidos en servicios de Medicina Interna españoles: estudio RELES.

INTRODUCTION: Patient registries are useful tools for assessing rare diseases. Our objective is to present the Spanish registry of patients with systemic lupus erythematosus (Registro español de pacientes con lupus eritematoso sistémico, RELES). PATIENTS AND METHODS: RELES was started in 2008 as an observational, prospective, multicentre cohort registry that included patients from the time they were diagnosed. The registry's objective is to analyse the incidence and noninflammatory complications of systemic lupus erythematosus (SLE). The departments of internal medicine of 38 Spanish hospitals participate in this registry. RESULTS: A total of 298 patients with a mean age of 40.8±15.7 years were included, 88.9% of whom were women and 85.6% of whom were white. In the first visit, there was a predominance of joint manifestations (74.5%). One hundred and seventy-seven patients (59.4%) were positive for anti-native DNA. In these patients, there was a higher rate of lupus nephritis (26.7% vs. 14%, p=.009; relative risk [RR], 1.33), haemolytic anaemia (13.6% vs. 4.1%, p=.07; RR, 1.46) and lymphopenia (55.4% vs. 43.8%, p=.05; RR, 1.21). The median Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI 2K) score was 9.64 points (interquartile range, 4-13). The patients treated with antimalarial drugs before the diagnosis of SLE had a median SLEDAI score in the first visit of 5, compared with 8 for those who were not treated with these drugs (p=.02). CONCLUSIONS: RELES constitutes the first Spanish patient cohort with SLE recorded from the time of the diagnosis. The presence of anti-DNA has been related to severe manifestations such as nephritis and haemolytic anaemia. Treatment with antimalarial drugs before the diagnosis was associated with less active disease at the initial presentation.

First month prednisone dose predicts prednisone burden during the following 11†months: an observational study from the RELES cohort.

AIM: To study the influence of prednisone dose during the first month after systemic lupus erythematosus (SLE) diagnosis (prednisone-1) on glucocorticoid burden during the subsequent 11 months (prednisone-2-12). METHODS: 223 patients from the Registro Español de Lupus Eritematoso Sistémico inception cohort were studied. The cumulative dose of prednisone-1 and prednisone-2-12 were calculated and recoded into a four-level categorical variable: no prednisone, low dose (up to 7.5 mg/day), medium dose (up to 30 mg/day) and high dose (over 30 mg/day). The association between the cumulative prednisone-1 and prednisone-2-12 doses was tested. We analysed whether the four-level prednisone-1 categorical variable was an independent predictor of an average dose >7.5 mg/day of prednisone-2-12. Adjusting variables included age, immunosuppressives, antimalarials, methyl-prednisolone pulses, lupus nephritis and baseline SLE Disease Activity Index (SLEDAI). RESULTS: Within the first month, 113 patients (51%) did not receive any prednisone, 24 patients (11%) received average low doses, 46 patients (21%) received medium doses and 40 patients (18%) received high doses. There was a strong association between prednisone-1 and prednisone-2-12 dose categories (p<0.001). The cumulative prednisone-1 dose was directly associated with the cumulative prednisone-2-12 dose (p<0.001). Compared with patients on no prednisone, patients taking medium (adjusted OR 5.27, 95% CI 2.18 to 12.73) or high-dose prednisone-1 (adjusted OR 10.5, 95% CI 3.8 to 29.17) were more likely to receive prednisone-2-12 doses of >7.5 mg/day, while patients receiving low-dose prednisone-1 were not (adjusted OR 1.4, 95% CI 0. 0.38 to 5.2). If the analysis was restricted to the 158 patients with a baseline SLEDAI of ≥6, the model did not change. CONCLUSION: The dose of prednisone during the first month after the diagnosis of SLE is an independent predictor of prednisone burden during the following 11 months.

Clinicopathological correlations and prognostic factors in lupus nephritis.

OBJECTIVE: To define prognostic factors at the moment of the diagnosis in lupus nephritis, and to assess the contribution of renal histologic data. PATIENTS AND METHODS: Sixty-two patients with systemic lupus erythematosus (SLE) and histologic evidence of nephritis were studied for renal outcome. Correlations between clinical or biological and histological data were carried out as an indicator of the utility of the renal biopsy. RESULTS: There were no significant differences in creatinine between the different histologic classes at the moment of the diagnosis, although the WHO classification correlated well with proteinuria and immunologic activity. There was a strong correlation between clinical and histological activity as measured by the activity index in proliferative glomerulonephritis, mainly with creatinine and proteinuria, but not with haematuria or immunological activity. Young age at the time of renal biopsy, proliferative classes III and IV, and the chronicity index were associated with a poorer renal prognosis. CONCLUSIONS: High immunologic activity, mainly elevated anti-DNA titers and decreased levels of CH100, is highly suggestive of proliferative glomerulonephritis. Proliferative classes III and IV and high chronicity indexes are associated with a worse prognosis in lupus nephritis.

[The involvement of the parenchyma of the central nervous system in Behçet disease]. / Afectación parenquimatosa del sistema nervioso central en la enfermedad de Behçet.

INTRODUCTION: Behçet disease is a systemic form of vasculitis which presents with neurological symptoms with a frequency varying between 16 and 40%. Involvement of the parenchyma has been found to worsen the prognosis in patients with neuroBehçet (NB). OBJECTIVE: To review the clinical features and course of patients with NB involving the parenchyma of the central nervous system (CNS). CLINICAL CASES: Seven patients with Behçet disease and neurological localizing signs were seen in our hospital between 1989 and 1996. The initial diagnosis was of ischemic ictus in five of the seven patients. Both neuroimaging studies and investigation of the cerebrospinal fluid were always pathological in all cases. Vascular studies (arteriography and echo-Doppler of the supra-aortic trunks) were normal. One patient died. Four patients had serious sequelae following treatment. CONCLUSION: NB should be included in the different diagnosis of ictus. Involvement of the parenchyma of the CNS was accompanied by lymphocytic meningitis, perhaps also leading to a worse functional prognosis.

[Osteonecrosis in systemic lupus erythematosus. Report of 3 cases]. / Osteonecrosis en el lupus eritematoso sistémico. Presentación de tres casos.

We present three cases of patients with systemic lupus erythematosus (SLE) and osteonecrosis or avascular necrosis (AV). Although, the pathogenesis of osteonecrosis is controversial and multifactorial, the glucocorticoids therapy is the most important factor contributing to the lesion. We report the clinical presentation of the three patients. We comment the characteristics of AV, the diagnosis and the treatment of this uncommon complication in SLE patients.

Nuestro objetivo es presentar el «Registro español de pacientes con lupus eritematoso sistémico» (RELES). Pacientes y métodos. RELES se inició en 2008, como un registro multicéntrico de cohortes, observacional, prospectivo, incluyendo a pacientes desde el momento del diagnóstico, cuyo objetivo es analizar la incidencia y complicaciones no inflamatorias del lupus eritematoso sistémico (LES). Participan los servicios de Medicina Interna de 38 hospitales españoles. Resultados. Se incluyó a 298 pacientes con una edad media de 40,8±15,7 años, de los que el 88,9% eran mujeres y el 85,6% de raza caucásica. En la primera visita, predominaron las manifestaciones articulares (74,5%). Ciento setenta y siete pacientes (59,4%) mostraban positividad para anti-DNA nativo, siendo superior en estos la frecuencia de nefritis lúpica (26,7% vs. 14%, p=0,009; riesgo relativo [RR] 1,33), de anemia hemolítica (13,6% vs. 4,1%, p= 0,07; RR 1,46) y linfopenia (55,4% vs. 43,8%, p=0,05; RR 1,21). La mediana del Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI 2K) fue de 9,64 puntos (rango intercuartílico 4-13). Los tratados con antipalúdicos antes del diagnóstico de LES tenían una mediana de SLEDAI en la primera visita de 5, frente a 8 en los que no los tomaban (p=0,02). Conclusiones. RELES constituye la primera cohorte de pacientes con LES recogidos desde el momento del diagnóstico en España. La presencia de anti-DNA se ha relacionado con manifestaciones graves como nefritis y anemia hemolítica. El tratamiento con antipalúdicos antes del diagnóstico se asoció con una enfermedad menos activa al comienzo (AU)

Dual effects of interleukin 4 on antigen-activated human B cells: induction of proliferation and inhibition of interleukin 2-dependent differentiation.

We analyzed the effects of interleukin 2 (IL 2) and IL 4 isolated and in association on the specific response of human B cells triggered by trinitrophenylated polyacrylamide beads (TNP-PAA). IL 2 induced an increase (more than 10 times) in the number of hapten-binding cells [detected by a rosette-forming cell (RFC) assay] as well as the generation of antibody-producing cells [detected by a plaque-forming cell (PFC) assay]. IL 4 induced an isolated RFC response without PFC response. We verified that the IL 4 (as well as 12)-induced RFC were hapten specific and mediated through membrane IgM. Density fractionation experiments showed that IL 4-induced RFC were equally distributed between high-density and intermediate-density B cells. IL 2 appeared to drive more B cells into the intermediate density fraction. IL 2-induced PFC belonged to the RFC population and were intermediate-size B cells. IL 2 drove more RFC into an activated stage and it induced the differentiation of a number of them into antibody-producing cells. The evaluation of the proportion of RFC able to incorporate thymidine showed that both IL induced a substantial proliferation of antigen-activated B cells. However, IL 4 inhibited the IL 2-dependent PFC without affecting the number of RFC nor the proportion of proliferating RFC induced by this IL. These results directly demonstrate that human IL 4 triggers the expansion of antigen-activated B cells and selectively inhibits the IL 2-induced differentiation.

Loss of bone mineral density in premenopausal women with systemic lupus erythematosus.

OBJECTIVE: To evaluate bone mineral density (BMD) in premenopausal patients with systemic lupus erythematosus (SLE). METHODS: We measured BMD by dual energy x ray absorptiometry at lumbar vertebrae L2-4 and at the right femoral neck in 74 premenopausal white patients (mean age 30.8 years) with SLE who were receiving glucocorticoid therapy, and in a control group. RESULTS: The mean cumulative dose of prednisone was 32.5 (SD 28) g. The mean dose at the time of absorptiometry was 13.7 (6.9) mg. BMD was significantly reduced at the spine and at the femoral neck in SLE patients when compared with the control group: L2-4 = 0.943 (0.1) g/cm2 v 1.038 (0.1) g/cm2 (p < 0.001); femoral neck = 0.766 (0.09) g/cm2 v 0.864 (0.1) g/cm2 (p < 0.001). Nine patients (12.1%), but none of the control group, had a BMD less than the reference range. CONCLUSION: BMD in premenopausal patients with SLE was less than that in a control group and less than the reference range of values defining the presence of osteoporosis in 12.1%. We did not find a relationship between BMD and either cumulative or baseline dose of corticosteroid therapy.

[Herpes-zoster virus infection in patients with systemic lupus erythematosus]. / Infección por virus del herpes zoster en pacientes con lupus eritematoso sistémico.

The prevalence of infection with VZV in 145 patients with SLE was investigated, with a mean follow-up of 7.6 years; its relationship with different variables, particularly with therapy of the underlying disease, was analyzed. Twenty episodes of VZV infection in 19 patients were diagnosed (13.1%). In no case was the therapeutic regime changed nor was worsening of SLE observed. There was neither dissemination of herpes nor superinfection. An increase in the number of VZV infections was observed in patients with SLE under corticosteroid therapy (p = 0.04) and particularly when drug administration was on a daily basis (p = 0.00006). Cytotoxic agents also favored the infection (p = 0.0014). VZV infection is of a benign nature in SLE and its emergence is favored by immunosuppressive agents. The risk is lower if corticosteroid administration is on alternate days. There is no need to decrease therapy for SLE.

Chronic ascites in late onset systemic lupus erythematosus with antiphospholipid antibodies.

Because doctors are reluctant to diagnose systemic lupus erythematosus (SLE) in elderly patients, the initial diagnosis in this age group is usually tardy. Furthermore, the presenting manifestations in these patients are commonly atypical. We describe a 72-year-old woman in whom chronic ascites with antiphospholipid antibodies was the initial predominant manifestation of subsequently fatal SLE. Only 13 cases of chronic lupus ascites have been reported in the English and French literature. Our patient represents the first case reported in an elderly person.

Mild presentation of systemic lupus erythematosus in elderly patients assessed by SLEDAI. SLE Disease Activity Index.

OBJECTIVE: Systemic lupus erythematosus (SLE) predominantly affects young patients. SLE starting in later life has a clinical presentation different than in younger patients. We have used the SLE Disease Activity Index (SLEDAI) to explore the relationship between age of onset and disease activity. METHODS: We selected all patients controlled in our hospital at the moment of clinical diagnosis of SLE (100 patients; 85 females and 15 males). They were classified in two groups: those with early onset (>50 y) and those with late onset (>50 y) based on their age at the moment of clinical diagnosis of SLE. RESULTS: In 12 patients the onset of SLE was >50 y (10 females and two males; mean age 59 y). The early onset patients had significantly higher SLEDAI values at the presentation and during the first year of disease with respect to elderly patients. Antibodies to DNA and hypocomplementemia were detected more often in younger patients. CONCLUSION: Our results confirm using SLEDAI, that the lupus of the elderly patients is a distinct clinical subgroup with a milder course of disease.

High disease activity at baseline does not prevent a remission in patients with systemic lupus erythematosus.

OBJECTIVE: To evaluate the utility of systemic lupus erythematosus (SLE) initial clinical manifestations and the SLE Disease Activity Index (SLEDAI) for identifying patients who will have a remission. METHODS: We studied 100 SLE patients (85 females, 15 males) and identified all patients who had remission (defined as at least one continuous year during which lack of disease activity permitted withdrawal of all treatment to suppress general lupus activity of a particular clinical manifestation). Changes in laboratory parameters without clinical activity, thus not requiring treatment, did not invalidate remission. We did not include any patient who had never required treatment. We evaluated the SLEDAI values and the main SLE manifestations at the time of diagnosis of SLE, and also every 3 months during the first year of disease. RESULTS: Twenty-four of the 100 SLE patients achieved remission that occurred a mean of 64 months after the diagnosis. They remained in remission for a mean of 55 months. There were no statistical differences in SLEDAI values and the initial manifestations (including renal and cerebral) between patients who reached remission and those who did not. The patients who have a higher SLEDAI score take longer to achieve remission. CONCLUSION: SLE patients with severe initial clinical manifestations and higher SLEDAI values may achieve clinical remission.

Bone mineral density and hormonal status in men with systemic lupus erythematosus.

A loss in bone mass was reported in premenopausal systemic lupus erythematosus (SLE) women, but this problem has not been studied in SLE males. We evaluated bone mineral density (BMD) in SLE males and the relationship between prolactin (PRL) and testosterone with BMD. We also studied the controversial effect of steroid therapy on BMD in these patients. We measured BMD in the lumbar spine and at the hip in 20 SLE men (mean age 37 y) and in the controls (n = 40). We measured PRL and testosterone in serum and saliva. The mean dose of prednisone at the time of study was 11.6 mg; and cumulative dose was 17.6 g. No significative decrease in BMD was detected in SLE males vs controls; either in the lumbar spine (1.00 +/- 0.1 vs 1.05 +/- 0.1 g/cm2) or in the femoral neck (0.84 +/- 0.1 vs 0.87 +/- 0.1 g/cm2). No patient or control had osteoporosis or fractures. We did not find any relationship between BMD and cumulative dose and baseline dose of corticosteroids. The mean values of PRL and testosterone (serum and salivary) were in the normal range. We did not find any correlation between BMD, PRL and androgens. This study did not show a loss in bone mass in SLE men on corticosteroid therapy.

[Antiphospholipid antibodies and epilepsy in patients with systemic lupus erythematosus]. / Anticuerpos antifosfolípido y epilepsia en los pacientes con lupus eritematoso sistémico.

OBJECTIVE: To verify the possible relationship between the presence of antiphospholipid antibodies (APLA) and the presence of epileptic seizures in patients with systemic lupus erythematosus (SLE). METHODS: A total of 168 patients with SLE were studied. Fifteen patients had antecedents of epilepsy which were non attributable to a cause other than SLE. Epilepsy was diagnosed on clinical and electroencephalographic grounds. Antibodies to cardiolipin (CLa) and lupus anticoagulant (LA) were measured. RESULTS: Epileptic seizures were generalized in 13 and partial in two patients. The lupus anticoagulant was positive in 40% of patients with epilepsy compared to 32% in the control group; CLa IgG in 53.5% compared to 65.6%, and CLa IgM in 40% compared to 35.2%. Differences were never statistically significant. Neither when patients with moderate/high CLa levels were studied. Seven patients (40%) had some of the classical manifestations of antiphospholipid syndrome. CONCLUSIONS: No association was found between positive APLA and epilepsy in patients with SLE.
