RESUMO

Objectives The objectives of this study were to examine the demographic and clinical features associated with the occurrence of pleuropulmonary manifestations, the predictive factors of their occurrence and their impact on mortality in systemic lupus erythematosus (SLE) patients. Materials and methods The association of pleuropulmonary manifestations with demographic and clinical features, the predictive factors of their occurrence and their impact on mortality were examined in GLADEL patients by appropriate univariable and multivariable analyses. Results At least one pleuropulmonary manifestation occurred in 421 of the 1480 SLE patients (28.4%), pleurisy being the most frequent (24.0%). Age at SLE onset ≥30 years (OR 1.42; 95% CI 1.10-1.83), the presence of lower respiratory tract infection (OR 3.19; 95% CI 2.05-4.96), non-ischemic heart disease (OR 3.17; 95% CI 2.41-4.18), ischemic heart disease (OR 3.39; 95% CI 2.08-5.54), systemic (OR 2.00; 95% CI 1.37-2.91), ocular (OR 1.58; 95% CI 1.16-2.14) and renal manifestations (OR 1.44; 95% CI 1.09-1.83) were associated with pleuropulmonary manifestations, whereas cutaneous manifestations were negatively associated (OR 0.47; 95% CI 0.29-0.76). Non-ischemic heart disease (HR 2.24; 95% CI 1.63-3.09), SDI scores ≥1 (OR 1.54; 95% CI 1.10-2.17) and anti-La antibody positivity (OR 2.51; 95% CI 1.39-4.57) independently predicted their subsequent occurrence. Cutaneous manifestations were protective of the subsequent occurrence of pleuropulmonary manifestations (HR 0.62; 95% CI 0.43-0.90). Pleuropulmonary manifestations independently contributed a decreased survival (HR: 2.79 95% CI 1.80-4.31). Conclusion Pleuropulmonary manifestations are frequent in SLE, particularly pleuritis. Older age, respiratory tract infection, cardiac, systemic and renal involvement were associated with them, whereas cutaneous manifestations were negatively associated. Cardiac compromise, SDI scores ≥1 and anti-La positivity at disease onset were predictive of their subsequent occurrence, whereas cutaneous manifestations were protective. They independently contributed to a decreased survival in these patients.

RESUMO

The objective of the study is to find predictors of remission, radiographic progression (RP), and erosive disease in a cohort of patients with early onset rheumatoid arthritis (EORA) that followed a therapeutic protocol aiming at remission, in a real world tight-control setting. EORA patients were enrolled in a 3-year follow-up study. Clinical, biological, immunogenetic, and radiographical data were analyzed. Radiographs were scored according to Sharp-van der Heijde (SvdH) method. RP was defined by an increase of 3 units in 36 months. Remission was defined as DAS28 <2.6. A stepwise multiple logistic regression model was used to identify independent predictors of the three target outcomes. One hundred twenty-nine patients were included. Baseline disease activity was high. Significant overall improvement was observed, but only 33.3 % achieved remission. At 36 month, 50.4 % (65) of patients showed erosions. RP was observed in 62.7 % (81) of cases. Statistical analysis showed that baseline SvdH score was the only predictive factor associated with the three outcomes evaluated. Lower HAQ-DI and absence of autoantibodies were predictive of remission. Higher levels of ESR and presence of erosions at entry were predictive of RP. Independent baseline predictors of incident erosive disease were anti-CCP and RF positivity, symptom duration at baseline >3 months, and presence of HLA-DRB1 shared epitope. Radiographic damage at baseline was the main predictor of outcomes. Autoantibodies, HAQ and ESR at baseline, symptom duration before diagnosis, and HLA-DRB1 status had influence on clinical course and development of structural joint damage in Colombian RA patients.

RESUMO

INTRODUCTION: Late-onset systemic lupus erythematosus (SLE) represents a specific subgroup that is defined as onset after 50 years of age. Late-onset lupus may have a different clinical course and serological findings, which may delay diagnosis and timely treatment. OBJECTIVES: The objective of this paper is to determine the clinical, serologic, and immunogenetic differences among Colombian patients with late-onset SLE versus conventional SLE patients. METHODOLOGY: This was a cross-sectional study in a Colombian population. Patients and their medical records were analyzed from the services of Rheumatology in Bogotá and met the criteria for SLE, according to the American College of Rheumatology (ACR) revised criteria for the classification of SLE.In a reference group of late-onset SLE patients (98 participants, with an onset after 50 years of age) and a group of conventional SLE patients (72 participants, with an onset of age of 49 years or less), multiple clinical variables (age, clinical criteria for lupus, alopecia, weight loss, fever, Raynaud's phenomenon) and multiple serological variables (blood count, blood chemistry profile, autoantibodies) were analyzed. Additionally, the HLA class II (DRB1) of all the patients was genotyped, including an additional group of patients without the autoimmune disease. Statistical analysis was performed using the STATA 10.0 package. RESULTS: In the group of late-onset lupus, there was a higher frequency of pleurisy (p = 0.002), pericarditis (p = 0.026), dry symptoms (p = 0.029), lymphopenia (p = 0.007), and higher titers of rheumatoid factor (p = 0.001) compared with the group of conventional SLE. Late-onset SLE patients had a lower seizure frequency (p = 0.019), weight loss (p = 0.009), alopecia (p < 0.001), and Raynaud's phenomenon (p = 0.013) compared to the conventional SLE group. In late-onset SLE, HLA DR17 (DR3) was found more frequently compared with individuals without autoimmune disease (OR 3.81, 95% CI 1.47 to 10.59) (p = 0.0016). CONCLUSION: In the Colombian SLE population analyzed, there may be a probable association of several clinical and serologic variants, which would allow the differentiation of variables in the presentation of the disease among patients with late-onset SLE vs. conventional SLE.

RESUMO

Relapsing polychondritis (RP) is an autoimmune disease characterized by inflammation and destruction of all type of body cartilage, and the cartilage trauma may be a trigger of the disease in a susceptible person. We describe the clinical and laboratory findings in a group of 18 patients with RP with (7 cases) or without (11 cases) anteceding cartilage trauma. The mean age was 41 years in the group with cartilage trauma and 55 years in the group without cartilage trauma. For both groups, female gender was predominant. All patients presented with auricular chondritis. Systemic manifestations and autoimmunity were more common in patients with anteceding trauma.

RESUMO

We have previously developed and validated a self-administered questionnaire, modelled after the Systemic Lupus International Collaborating Clinics Damage Index (SDI), the Lupus Damage Index Questionnaire (LDIQ), which may allow the ascertainment of this construct in systemic lupus erythematosus (SLE) patients followed in the community and thus expand observations made about damage. We have now translated, back-translated and adapted the LDIQ to Spanish, Portuguese and French and applied it to patients followed at academic and non-academic centres in North and South America, Portugal and Spain while their physicians scored the SDI. A total of 887 patients (659 Spanish-speaking, 140 Portuguese-speaking and 80 French-speaking patients) and 40 physicians participated. Overall, patients scored all LDIQ versions higher than their physicians (total score and all domains). Infrequent manifestations had less optimal clinimetric properties but overall agreement was more than 95% for the majority of items. Higher correlations were observed among the Spanish-speaking patients than the Portuguese-speaking and French-speaking patients; further adjustments may be needed before the Portuguese and French versions of the LDIQ are applied in community-based studies. The relationship between the LDIQ and other outcome parameters is currently being investigated in a different patient sample.

RESUMO

Propuesta: las vasculitis primarias se expresan de forma variable entre pacientes y entre regiones, con frecuencias variables a través del mundo. Su incidencia promedio está calculada en 0,3 a 20 casos por millón de habitantes. Nosotros describimos la frecuencia de las vasculitis primarias en Colombia y la comparamos con lo informado en otros países de Latinoamérica (LA). Métodos: se revisó lo publicado en la literatura de vasculitis primaria en Colombia y en LA desde 1945 hasta 2007 en OLD Medline, Pub Med, BIREME, SciELO Colombia, LILACS. FEPAFEN, incluyendo publicaciones en inglés, español y portugués. La literatura incluye la información publicada del Hospital San Juan de Dios, Bogotá, Colombia y casos sin publicación enviados directamente por los autores. Nosotros calculamos el porcentaje para todos los casos que fueron informados para Colombia. Resultados: se identificaron 857 casos de vasculitis primaria en Colombia. La arteritis de Takayasu fue la vasculitis más frecuente en un 13,3% (114 casos) seguida de la enfermedad de Buerger en 11,2% (96 casos), las vasculitis cutáneas primarias y la poliarteritis nodosa en un 10% (86 casos) cada una. En niños, la vasculitis más frecuente fue la púrpura de Henoch Schönlein en un 24% (206 casos). En Latinoamérica se publicaron 177 artículos con 1605 casos informados. Se evidenció mayor presencia de arteritis de Takayasu en México y Brasil, y de poliangeítis microscópica en Chile y Perú. Conclusión: la mayoría de publicaciones sobre vasculitis primarias provienen de Europa, Norteamérica, Japón, Kuwait y Nueva Zelanda. Existen una serie de publicaciones y experiencia con estas patologías en LA. Un número considerable de publicaciones y casos con vasculitis primarias se han informado en Colombia en los recientes años, incluyendo la reciente descripción de la variante nodular de la vasculitis cutánea. La arteritis de Takayasu fue la variante más reportada del promedio de vasculitis, al igual que en Brasil y México. En contraposición a los hallazgos realizados en Brasil, Colombia y Mexico, las vasculitis asociadas a ANCA fueron la forma más informada en países como Chile y Perú. La mayoría de casos informados en LA provienen de México, siendo Colombia el segundo país en frecuencia. Es posible que exista más información pero no la conocemos, por no estar publicada. No existen estudios de incidencia y prevalencia. A escala mundial solo existen estudios de incidencia de las vasculitis primarias, y solo se han realizado estudios de incidencia y prevalencia en la granulomatosis de Wegener.

Purpose: primary vasculitis occurs with variable expression in individual patients and regions, and variable frequency throughout the world. Their overall incidence has been calculated to be 40 cases per million populations. We sought to describe the frequency of vasculitis in Colombia and compare it with vasculitis reported from other countries of Latin America (LA). Methods: review of available published literature on vasculitis in LA from 1945 to 2007 in OLD Medline, Pub Med, BIREME, SciELO Colombia, LILACS, FEPAFEN, including publications in English, Spanish and Portuguese. The literature included published information from San Juan de Dios hospital, Bogota, Colombia, and unpublished cases submitted directly to the authors. We calculated the percentage of all cases which are reported from Colombia. Results: we identified 857 cases of primary vasculitis in Colombia. Takayasu arteritis was the most common vasculitis in 13.3% (114 cases) followed by Buerger's disease in 11.2% (96 cases), primary cutaneous vasculitis and polyarteritis nodosa in a 10% (86 cases) each. In children, the vasculitis was more frequent in Henoch Schonlein purpura in 24% (206 cases). In Latin America, 177 articles were published in 1605 reported cases. It showed increased presence of Takayasu's arteritis in Mexico and Brazil, and microscopic poliangeiitis in Peru and Chile. Conclusion: while the majority of publications on primary vasculitis are from Europe and North America, there is a substantial literature and experience with these disorders in LA. A considerable number of publications and cases have emerged from Colombia in recent years, including case descriptions of a recently described variant of nodular cutaneous vasculitis. Takayasu arteritis was the most frequently reported form of primary vasculitis overall, and also from Brazil and Mexico. However, ANCA related vasculitis were the most commonly reported forms in Chile and Peru instead. The greatest numbers of cases were reported from Mexico, the LA's most populous country, with Colombia a close second.

RESUMO

OBJECTIVE: To describe the occurrence of erosive arthropathy in systemic lupus erythematosus (SLE) and its relationship to anti-CCP antibodies. METHODS: Retrospective medical record review of a case series of five female patients with SLE and erosive arthropathies. RESULTS: The initial disease presentation in all patients was a polyarthritis. Anti-CCP antibodies were detected in 4 out of 5 (80%) patients, 2 of whom had a positive rheumatoid factor. CONCLUSION: Erosive arthritis was strongly associated with the presence of anti-CCP antibodies in these patients with SLE, who presented with polyarthritis. Anti-CCP in patients with SLE may be a marker of a more severe joint disease.

RESUMO

BACKGROUND: Poststreptococcal reactive arthritis (PSReA) is a recognized inflammatory articular syndrome that follows group A streptococcal infection in persons not fulfilling the Jones criteria for the diagnosis of acute rheumatic fever. Characteristic features include nonmigratory arthritis, lack of response to aspirin or nonsteroidal anti-inflammatory agents, and the presence of extra-articular manifestations, including vasculitis and glomerulonephritis. Whether or not patients with PSReA develop carditis is a point of contention. METHODS: We analyzed the clinical features, laboratory findings, response to therapy, and outcome in patients diagnosed with PSReA between 1983 and 1998 and observed through April 2000. All patients were contacted, reexamined, and repeat antistreptolysin, rheumatoid factor, C3 and C4 complement components, and echocardiograms were performed. RESULTS: Seventeen patients (4 men and 13 women) were included. All were of low socioeconomic status. All patients had acute severe arthritis that began shortly after a sore throat episode. Extra-articular involvement including tenosynovitis, vasculitis, and glomerulonephritis was relatively common. More importantly, none exhibited clinical and/or echocardiographic evidence of cardiac involvement. Longterm antibiotic therapy was not given. CONCLUSION: Cardiac involvement did not occur in this group of patients with PSReA. Prolonged prophylactic antibiotic therapy may not be required for adult patients presenting with PSReA.

RESUMO

We performed HLA Class I and Class II typing in 16 patients (15 women, one man) with a confirmed diagnosis of Takayasu arteritis. We did not find any of the previously described associations with HLA-B52, and/or HLA-DRB1*1301 alleles. However, in our patients, HLA-DRB1*1602 and HLA-DRB1*1001 were significantly increased. The association of Takayasu arteritis with Amerindian and Asian HLA-DRB1 alleles (DRB1*1602 and DRB1*1001) in the Colombian mestizo patients reported here, and with HLA-B*3906 previously reported in Mexicans, suggest the possibility that some HLA and disease associations are markers for ethnicity of a population carrying a disease gene which is present in an admixed population with the disease.

RESUMO

OBJECTIVE: We investigated the distribution of HLA-B27 subtypes in patients with ankylosing spondylitis (AS) belonging to two ethnic groups of Colombia. MATERIAL AND METHODS: PCR-SSOs was used to detect the polymorphism in exons 2 and 3 of HLA-B27 in two groups of patients: 39 Mulattos and 20 Mestizos. Fifty-nine of them suffered of ankylosing spondylitis (AS), including two patients with ankylosing spondylitis plus anterior uveitis (AU). Only two out of eight HLA-B27 subtypes studied (B*2701-B*2708) were found. RESULTS: The distribution of these alleles in the whole population was: B*2705: 87.1% and B*2702: 12.8% in the Mulattos group; 80% were B*2705 and 20% B*2702 in Mestizos group. The distribution of HLA-B27 subtypes was: 84.74% of patients with AS were B*2705 and 15.26% B*2702. CONCLUSIONS: There was no significant difference in the distribution of HLA-B27 subtypes among the patients ethnic groups studied. Other authors have shown that B*2705, B*2702 and B*2704, the more frequent subtypes, are equally associated to the disease. Although population studies need to be done to analyze the distribution of subtypes between patients and controls, the low frequency of HLA-B27 within the normal population does not permit to do a representative number of controls; our results suggest that HLA-B*2705 and HLA-B*2702 are the subtypes more frequently associated with AS in patients from the two more prevalent patients ethnic groups in Colombia.

RESUMO

OBJECTIVES: To know the clinical characteristics in the presentation of Buerger's disease in San Juan de Dios Hospital, Bogota, Colombia, between 1986 and 1996, and compare them with a previous series from the same Hospital and another reported in international literature; To determine the changes in the form of appearance of the disease. METHODS: We reviewed the clinical information of 22 patients with diagnosis of Buerger's disease, observed between 1986 and 1993, and we added the information of the clinical histories of eight other patients with equal diagnosis, observed between 1994 and 1996 in our Unit. RESULTS: We observed 30 patients: 28 men (93%) and two women (7%), with a ratio M:F of 14:1, with an average age of 39+10 years (range from 18 to 52 years). Sixty percent were younger than 40 years and only the 10% were older than 50 years. The most frequent reasons for consultation were: pain in rest in the affected extremity, gangrene and ulceration in more than 50%. Raynaud's phenomenon in 30%, and the related surgical history in 40%. The pedal pulse was the most compromised followed by popliteal, poster or tibial and femoral. We did not observe the presence of thrombophlebitis. Eighty percent showed compromise of more than one extremity. All of them were active smokers. Three patients showed IgG anticardiolipine antibodies at high level. CONCLUSIONS: The clinical characteristics are similar to those reported, we find also a reduction of the disease diagnosis. It calls to our attention that no thrombophlebitis was found in the present series and the less compromise of the upper extremities with a frequent femoral compromise. All this points toward a change in the natural history of the disease.

RESUMO

Osteopoikilosis is a benign and rare disorder characterized by abnormal calcium phosphate deposition in the articular cartilage. It usually is an incidental radiologic finding. Chondrocalcinosis is characterized by calcium pyrophosphate deposition in the articular cartilage. Both diseases can be asymptomatic. We describe some radiographic features that distinguish osteopoikilosis from other similar conditions and report a young female patient with osteopoikilosis associated with chondrocalcinosis. To the best of our knowledge, this is the first time these processes have been found in the same patient.

RESUMO

A case presentation of a patient with SLE associated with papulonodular mucinosis, generalized lymphadenopathy and splenomegaly is reported, along with a review of the literature. This 24 year old woman had biopsy-proven, skin lesions consistent with dermal mucinosis and a non-homogeneous immunofluorescence pattern. Serum anti-nuclear and anti-DNA antibodies were present and a mesangioproliferative glomerulonephritis was documented. The patient responded dramatically to standard therapy with prednisolone. The nature of the mucin deposits and the pattern of immunofluorescence deposition in the skin are discussed based on the findings reported in the literature.
