ABSTRACT
Pancreatitis complicating a diagnosis of systemic lupus erythematosus (SLE) is rarely reported in the literature and there are no known published cases thus far in the Caribbean. A 50-year old female diagnosed with SLE and discoid lupus erythematosus (DLE) since 1990, presented in February, 2009, to the University Hospital of the West Indies (UHWI), Kingston, Jamaica, with symptoms suggestive of lupus pancreatitis. Serum amylase level was 2341 IU/L and serum lipase was 203 IU/L. Pancreatitis has a 3-8% rate of occurrence in adult patients with SLE. Aetiology and management of this entity remains controversial in these cases, but one must bear the diagnosis in mind, when faced with a SLE patient presenting with abdominal pain, vomiting and diarrhoea.
La pancreatitis que complica el diagnóstico del lupus eritematoso sistémico (LES), raramente se reporta en la literatura, y hasta hoy no se conoce de caso alguno publicado en el Caribe. Una mujer de 50 años de edad, a quien se le diagnosticara lupus eritematoso sistémico (LES), y lupus eritematoso discoide (LED) desde 1990, acudió en febrero de 2009 al Hospital Universitario de West Indies, Kingston, Jamaica, con síntomas que sugerían una pancreatitis por lupus. El nivel de amilasa sérica fue 2341 IU/L y el de lipasa sérica fue 203 IU/L. La pancreatitis tiene una tasa de ocurrencia de 3-8% en pacientes adultos con LES. La etiología y el tratamiento de esta entidad siguen siendo controversiales en estos casos, pero se debe tener presente el diagnóstico frente a pacientes de SLE que presenten dolor abdominal, vómito y diarrea.

FUNDAMENTOS: Lesão discoide é a manifestação cutânea mais comum do lúpus eritematoso, e formas cutâneas crônicas apresentam características imunológicas próprias, direcionadas ao polo Th1. Diversas doenças possuem associação com grupos sanguíneos, o que não foi ainda estudado no lúpus discoide. OBJETIVO: Investigar a associação entre tipos sanguíneos (ABO e Rh) e lúpus eritematoso discoide. MÉTODOS: Estudo prospectivo tipo transversal envolvendo tipagem sanguínea ABO e Rh, inquérito de dados clínicos e dosagem de FAN e C4 de portadores de lúpus discoide sem critérios de doença sistêmica, atendidos em hospital universitário. RESULTADOS: Foram incluídos no estudo 69 pacientes, sendo 71,0 por cento do sexo feminino (p 1:160, em 31,9 por cento; e níveis baixos de C4, em 8,7 por cento. Não houve diferença significativa entre as frequências dos grupos sanguíneos dos pacientes e da população local; entretanto, o grupo A foi associado às formas disseminadas da doença (OR 4,1 e p < 0,05). CONCLUSÕES: Grupos sanguíneos de pacientes com lúpus discoide apresentam frequência semelhante à da população; porém, formas clínicas disseminadas foram mais prevalentes entre portadores do grupo A.
Background: Discoid lesion is the commonest cutaneous finding in lupus erythematosus and chronic types have their own immunological features, with Th1 inflammation profile. Although many diseases have association with blood-group systems, this fact was not enlightened in discoid lupus erythematosus. Objective: To investigate the association between blood groups (ABO and Rh) and discoid lupus erythematosus. Methods: A prospective cross-sectional study assessing clinical information, blood group systems (ABO and Rh), FAN and C4 serum levels from discoid lupus patients without characteristics of systemic disease, was carried out at a clinic from a Brazilian university hospital. Results: Sixty-nine patients were enrolled in the study, 71.0 percent were females (p1:160 in 31.9 percent, and low levels of C4 in 8.7 percent. There was no significant difference between the frequency of blood groups from discoid lupus patients and local population, however, blood group A was associated to disseminate forms of the disease (OR 4.1 and p < 0.05). Conclusions: Discoid lupus erythematosus patients with ABO and Rh blood groups exhibit similar frequencies as in the general population; nevertheless, disseminate clinical forms were more prevalent among group A patients.
