ABSTRACT
Abstract: BACKGROUND: Patients with systemic lupus erythematosus seem to belong to different serological and clinical subgroups of the disease. Genetic background can cause the appearance of these subgroups. OBJECTIVE: To determine whether Brazilian patients who have systemic lupus erythematosus and Raynaud's phenomenon differ from those who do not. METHODS: Retrospective analysis of 373 medical records of systemic lupus erythematosus patients studied for demographic, clinical and serological data. A comparative analysis was performed of individuals with and without RP. RESULTS: There was a positive association between Raynaud's phenomenon and age at diagnosis (p=0.02), presence of anti-Sm (p=0.01) antibodies and anti-RNP (p<0.0001). Furthermore, a negative association was found between Raynaud's phenomenon and hemolysis (p=0.01), serositis (p=0.01), glomerulonephritis (p=0.0004) and IgM aCL (p=0.004) antibodies. CONCLUSION: Raynaud's phenomenon patients appear to belong to a systemic lupus erythematosus subset with a spectrum of clinical manifestations located in a more benign pole of the disease.

JUSTIFICATIVA E OBJETIVOS: O abscesso esplênico é uma doença rara, porém com um número crescente de casos publicados nos últimos anos. Geralmente, resulta de disseminação hematogênica, especialmente relacionada à endocardite, mas também pode ocorrer por contiguidade e relacionada a outros focos infecciosos.A grande maioria dos casos ocorre em pacientes imunossuprimidos. A doença é responsável por graves complicações e apresenta alto índice de mortalidade na ausência de terapêutica adequada. Oobjetivo deste estudo foi lembrar aos clínicos dessa possibilidade diagnóstica, que exige alto grau de suspeição, devido ao quadro clínico inespecífico. RELATO DO CASO: Paciente do sexo feminino, 44 anos, com quadro clínico de dor abdominal difusa, mais acentuada em flanco esquerdo com evolução de um mês e febre de 40º C com início há 5 dias. Previamente hígida, exceto por história de hipertensão arterial sistêmica, insuficiência cardíaca e prótese metálica em valva mitral. Ao exame encontrava-se em regular estado geral, desorientada,hipotensa, com depleção extracelular de 30%, afebril e eupneica. O abdômen era plano, flácido, doloroso à palpação em flanco esquerdo e hipogástrio e sem sinais de irritação peritoneal. Realizada tomografia computadorizada, que evidenciou imagem hipodensa no interior do baço. Diagnosticado abscesso esplênico,sendo tratada com esplenectomia e antibioticoterapia. CONCLUSÃO: Esse relato demonstrou que o abscesso esplênico pode ocorrer em pacientes imunocompetentes e sem outra fonte de infecção.
BACKGROUND AND OBJECTIVES: Splenic abscess is a rare disease, however the number of cases published in literature has increase in recent years. Generally, it appears after hematogenous dissemination, especially related with endocarditis, but can also occurby contiguity and related with other infections sites. The majorityof the cases happen in immunocompromised hosts. The disease is responsible for serious complications and has high mortality rate without appropriate treatment. The objective of this report was to remind doctors of this diagnostic, which needs a high degree of suspicion due its nonspecific clinical manifestation. CASE REPORT: Female patient, 44-years-old, with clinical symptoms of diffuse abdominal pain, more important in left flank,with one month of evolution, and 40º C fever that started withinfive days. Previously healthy, except for history of hypertension,cardiac failure and metallic prosthesis in the mitral valve. On examinationshe was in regular condition, disoriented, hypotensive, with extracellular depletion of 30%, afebrile and eupneic. The abdomen was flat, flaccid, painful to palpation in the left flank and hypogastric and without signs of peritoneal irritation. A CT scan was performed which showed a hypodense image on spleen. Diagnosed splenic abscess, the patient was treated with splenectomy and antimicrobial therapy. CONCLUSION: This report showed that splenic abscess may occurin immunocompetents patients without other source of infection.
