[Use of intravenous humana immunoglobulin in rheumatic diseases]. / Uso de inmunogtlobulina G humana endovenosa(IGEV) en enfermedades reumáticas.

INTRODUCTION: Preparations of intravenous immunoglobulin (IVIG) are used as treatment in different diseases such primary and secondary immunodeficiencies, autoimmune diseases, systemic inflammatory diseases, infectious diseases and allergic diseases among others. OBJECTIVE: to present 13 of our cases with the use of IVIG in different rheumatic diseases. PATIENTS AND METHODS: we retrospectively studied 13 patients (10 women and 3 men), mean age 29 years with different rheumatic diseases, that underwent conventional treatments without positive response. They received IVIG pulses, trying to improve or induce remission of their previous clinical situation. 6/13 patients met criteria for systemic lupus erythematosus (SLE), 2/13 had primary antiphospholipid syndrome (APL)one had polydermatomyositis (PDM), 1 juvenile arthritis, 1 panarteritis nodosa (cutaneous PAN), one Evans syndrome, and one with autoimmune uveitis. RESULTS: 7 of them had a positive response to therapy with IGEV evaluated by clinical and biochemical parameters. They remained with conventional treatments. One patient received a new IG EV pulse after 24 months, because of panniculitis reactivation. Clinical and biochemical response was poor in 4 of them, and 2 patients died. CONCLUSION: IVIg may be usefull in autoimmune rheumatic diseases when conventional therapies have failed. The therapeutic success is also limited. Only the 55 percent of our patients had a positive clinical response.

Childhood systemic lupus erythematosus in Latin America. The GLADEL experience in 230 children.

To evaluate disease characteristics of childhood onset SLE in Latin America and to compare this information with an adult population in the same cohort of GLADEL. A protocol was designed as a multicenter, multinational, inception cohort of lupus patients to evaluate demographic, clinical, laboratory and serological variables, as well as classification criteria, disease activity, organ damage and mortality. Descriptive statistics, chi square, Fisher's exact test, Student's t test and multiple logistic regression were used to compare childhood and adult onset SLE. 230 patients were <18 years and 884 were adult SLE patients. Malar rash, fever, oral ulcers, thrombocytopenia and hemolytic anemia and some neurologic manifestations were more prevalent in children (p<0.05). On the other hand, myalgias, Sjögren's syndrome and cranial nerve involvement were more frequently seen in adults (p<0.05). Afro-Latin-American children had a higher prevalence of fever, thrombocytopenia and hemolytic anemia. White and mestizo children had a higher prevalence of malar rash. Mestizo children had a higher prevalence of cerebrovascular disease and cranial nerve involvement. Children met SLE ACR criteria earlier with higher mean values than adults (p: 0.001). They also had higher disease activity scores (p: 0.01), whereas adults had greater disease damage (p: 0.02). In Latin America, childhood onset SLE seems to be a more severe disease than adults. Some differences can be detected among ethnic groups.

[Hyperhomocysteine like thrombocytic risk factor in patient with systemic lupus erythematous with antiphospholipid syndrome]. / Hiperhomocisteinemia como factor de riesgo trombótico en pacientes con lupus eritematoso sistémico y síndrome antifosfolípido.

OBJECTIVES: to detect the prevalence of hyperhcy in SLE patients with and without antiphospholipid syndrom; to compare the Hcy levels between those patients and healthy controls and to determine the correlation between hyperhcy and antiphospholipid antibodies. PATIENTS AND METHODS: we studied 44 SLE patients: 17 had antiphospholipid syndrom and 27 didn't have it, and we compared them to 24 healthy controls. All of them where checked clinically and with laboratory tests like anticardiolypin antibodies, lupus anticoagulant and Hcy. Hcy > 9 was considered abnormal. Patient who had hyperhcy were treated with folic acid+vitB6+vitB12 a month along. STATISTICAL ANALYSIS: cualytative variables: chi square or Fischer's; cuantitative variables: Student's T test or Mann-Whitney's test. RESULTS AND CONCLUSIONS: there were 35 trombotic manifestations in 44 patients. Hyperhcy was present in 27 SLE patients (61,4%), 12 of them had antiphospholipid syndrom. Hcy concentrations patients vs.controls was statisticaly different (p=0,002). There was also stastisticaly different the hcy concentration from SLE patients with SAF vs controls (p=0,003) and without SAF vs controls (p= 0,015). From 33 SLE patients, 20 (33%) were aCL(+). 15(75%) of them had hiperhcy.

[Function of flow cytometry on the dosage of antibodies against double stranded DNA in systemic lupus erythematosus]. / Función de la citometría de flujo en el dosaje de anticuerpos anti-DNA de doble cadena en el lupus eritematoso sistémico.

BACKGROUND: Among the diverse number of antibodies observed in systemic lupus erythematosus, antibodies against double stranded DNA (anti-dsDNA) represent important serologic markers for the disease diagnosis and the follow-up of the disease activity. OBJECTIVE: To evaluate the role of a new quantitative methodology to detect antibodies against double stranded DNA in systemic lupus erythematosus and its association with the disease activity. MATERIAL AND METHODS: The performance of the indirect immunofluorescence flow cytometry with Crithidia luciliae as substrate was compared with the Crithidia luciliae indirect immunofluorescence assay and the ELISA technique in order to detect antibodies against double stranded DNA in 54 sera from 47 patient with systemic lupus erythematosus and 100 sera from normal controls. RESULTS: The new method showed a sensitivity of 78% and a specificity of 81% when the Crithidia luciliae indirect immunofluorescence assay was the gold standard. Compared with the ELISA technique, the flow cytometry showed a sensitivity of 78% and a specificity of 86%. No correlation was found among antibodies against double stranded DNA values detected with flow cytometry and the MEX-SLEDAI activity scores. However, the flow cytometry showed a sensitivity of 70% and a specificity of 42% to distinguish patients with systemic lupus erythematosus with and without activity (MEX-SLEDAI score > or = 5). The Rho intra-observer coefficient was 0.61 (p < 0.0001). CONCLUSIONS: In spite of the fact that this new method might represent an interesting advance for antibodies against double stranded DNA quantitative testing, a clear superiority does not emerge when it was compared with more traditional assays. Difficulties related with its reproducibility might represent a limitation in the routine use of this new method.

[Semester direct cost by rheumatoid arthritis in patients in a university hospital]. / Costo directo semestral por artritis reumatoidea en pacientes que concurren a un hospital universitario.

INTRODUCTION: There are no medical publications with economic analysis of rheumatoid arthritis patients (RA) from Argentina are lacking. The objective of the present study is to determine the direct cost and its breakdown in patients with RA. MATERIAL AND METHODS: Fifty-two patients who met the American College of Rheumatology RA criteria were included. Direct cost was calculated over a follow-up period of 6 months during year 2001. Variables were analyzed with Student's T test, Mann-Whitney U Test, c' or ANOVA as corresponded. P values < 0.05 were considered significant. RESULTS: The mean monthly home income was $426.6 SD 272. The mean half-yearly direct costs was $677.5 SD 376.2. The components of the direct cost were identified and the mean for medication cost was $606.7 (89%), for lab tests was $45.5 (7%), for medical attention $12.5 (2%) and other costs $2.4. No differences in total cost or in medication cost were found when compared considering age, evolution time of RA or HAQ scores. CONCLUSION: Half-yearly direct cost in RA is excessively high considering the monthly mean income of the patients being analyzed. The cost of medication was the principal component of the direct cost.

Eficacia, tolerabilidad y seguridad de la ciclosporina para microemulsion en el tratamiento de la artritis reumatoidea activa: estudio abierto / Efficacy, tolerability and safety of cyclosporine for microemulsion in the treatment of the active rheumatoid arthritis: open study

La ciclosporina para microemulsión (cpm) ha sido ampliamente utilizada para el tratamiento de la ar- tritis reumatoidea (AR) con muy buenos resultados sobre la progresión del daño articular según ha sido informado por el grupo de estudio GRISAR1. Para evaluar eficacia, seguridad y tolerabilidad de la cpm en el tratamiento de la AR un grupo local de 12 centros (50 pacientes), realizó un estudio abierto, prospectivo (Neo-Ra-02), de seis meses de seguimiento. Los parámetros considerados para evaluar la eficacia fueron: modificación de la rigidez matutina, pruebas funcionales (índices de HAQ, Ritchie y Lee), de laboratorio y radiológicos (índice de Larsen). Los parámetros usados para evaluar la seguridad fueron: tensión arterial y determinaciones de laboratorio de función renal, hepática y análisis hematológico. Los criterios para la participación de los pacientes fueron: presencia de AR activa (según definición del ACR), estadios anatómicos y funcionales de Steinbrocker del I al III, evolución de la enfermedad no mayor de 5 años, ausencia de historia previa de hipertensión arterial, enfermedad renal o hepática y ausencia de uso de drogas modificadoras de la enfermedad en los dos meses anteriores al estudio. A las 4 semanas del tratamiento se verificó disminución estadísticamente significativa del dolor, rigidez matutina, scores de sensibilidad, entumecimiento articular e índice de Ritchie. No hubo incremento significativo de la creatinina, ni del ácido úrico séricos. Seis casos desarrollaron hipertensión arterial leve. La cpm demostró eficacia con mínima incidencia de efectos adversos (12 por ciento de hipertensión arterial leve) cuando su administración fue en dosis bajas y adecuadamente monitoreada.

Acción de la auroterapia oral sobre la respuesta inmune de pacientes con artritis reumatoidea / Action of oral aurotherapy in immune response of rheumatoid arthritis patients

Se han estudiado las respuestas inmunes celular (RIC) y humoral (RIH) en 13 pacientes afectados de artritis reumatoides (AR) "definida" o "clásica", antes y después de 6 a 12 meses de tratamiento con 6mg/día de auranofin. Se ha observado un aumento en la frecuencia de positividad de algunas pruebas cutáneas (PPD, PHA, candidina) y de estimulación cutánea con DNCB, una reducción o negativización de los títulos de factor reumatoideo y del número de linfocitos B (rosetas EAC) y una normalización de los niveles séricos de IgG y complemento. Se concluye que el auranofin es capaz de influir positivamente en la RIC y normalizar algunos parámetros de la RIH, actuando como un inmunomodulador en el tratamiento de la AR
