- Brucelose osteo-articular: um retrato dos últimos 10 anosPublication . Santiago, T; Rovisco, J; Silva, J; Pereira da Silva, JAOBJECTIVES: Characterize Osteoarticular Brucellosis in the University Hospital of Coimbra (HUC) in the past decade. MATERIAL AND METHODS: A retrospective study of the cases diagnosed between January/2000 and December/2009 in the HUC. RESULTS: Ninety patients were admitted with the dia-gnosis of brucellosis in our hospital, of whom 44 (49%; 18 men; 26 women, mean 49.5 years) had osteoarticular complications. Twenty-five (45%) patients had a positive epidemiological context. The most frequent clinical manifestation was local pain (73%) followed by polyarthralgias and constitutional symptoms. The C-reactive protein was the inflammatory marker most often increased (82%). The Rose Bengala test was positive in 42 patients, and a Wright's sero-aglutination above than 1/160 was detected in 28 patients. An etiologic agent was isolated in 28 (64%) patients, with 70% of positive blood cultures. The imaging procedure of choice was magnetic resonance imaging (MRI) (46%). The osteo-articular manifestation most frequent was spondylodiscitis (57%) with a lumbosacral involvement in 40%. All patients completed antibiotic therapy. One patient underwent surgery to drain the abscess. Patients had an average length of admission of 28.3 days, with a good outcome in 60%, and a reasonable outcome in 20%, despite 20% of the patients lost follow-up. CONCLUSIONS: Brucellosis is a disease of obligatory declaration not eradicated in Portugal, with a great impact on socio-economic and public health. So, this epidemiological knowledge of brucellosis cases, allows an early intervention and therapy.
- A case of infliximab-induced lupus in a patient with ankylosing spondylitis: is it safe switch to another anti-TNF-α agent?Publication . Santiago, T; Santiago, MG; Rovisco, J; Duarte, C; Malcata, AB; Pereira da Silva, jaAnti-TNF-α therapies are the latest class of medications found to be associated with drug-induced lupus, a distinctive entity known as anti-TNF-α-induced lupus (ATIL) (Williams et al., Rheumatology (Oxford) 48:716-20, 2009; De Rycke et al., Lupus 14:931-7, 2005; De Bandt et al., Clin Rheumatol 22:56-61, 2003). With the widespread use of these agents, it is likely that the incidence of ATIL will increase. The onset of ATIL in patients with rheumatoid arthritis and Crohn's disease has been described, but the literature regarding the occurrence of this entity in patients with ankylosing spondylitis (AS) is scarce (De Bandt et al., Clin Rheumatol 22:56-61, 2003; Ramos-Casals et al., Autoimmun Rev 9:188-93, 2010; Perez-Garcia et al., Rheumatology 45:114-116, 2006). To our knowledge, few reports of switching anti-TNF-α therapy after ATIL in AS have been reported (Akgül et al., Rheumatol Int, 2012). Therefore, it is not clear whether the development of ATIL should prohibit switch to another therapy, since patients may respond to another anti-TNF-α agent (Akgül et al., Rheumatol Int, 2012; Bodur et al., Rheumatol Int 29:451-454, 2009; Mounach et al., Clin Exp Rheumatol 26:1116-8, 2008; Williams and Cohen, Int J Dermatol 50:619-625, 2011; Ye et al., J Rheumatol 38:1216, 2011; Wetter and Davis, Mayo Clin Proc 84:979-984, 2009; Cush, Clin Exp Rheumatol 22:S141-147, 2004; Kocharla and Mongey, Lupus 18:169-7, 2009). A lack of published experience of successful anti-TNF-α switching is a cause of concern for rheumatologists faced with this challenging clinical scenario. We report the case of a 69-year-old woman with AS who developed infliximab-induced lupus, which did not recur despite the subsequent institution of etanercept. The authors review and discuss ATIL and the possible implications for subsequent treatment with alternative anti-TNF-α agents.

- Coexisting primary Sjögren’s syndrome and sarcoidosis: coincidence, mutually exclusive conditions or syndrome?Publication . Santiago, T; Santiago, M; Rovisco, R; Ferreira, J; Duarte, C; Malcata, AB; Pereira da Silva, JAHerein, we describe a 44-year-old female diagnosed with histologically proven coexistence of primary Sjögren's syndrome and sarcoidosis with pulmonary and muscular involvement. The differential diagnosis may be difficult, but this is not an exceptional case, which highlights the need to critically revise the consideration of sarcoidosis as an exclusion for primary Sjögren's syndrome, as established in current classification criteria.

- Hipovitaminose D em doentes internados num serviço de medicina internaPublication . Santiago, T; Rebelo, M; Porto, J; Silva, N; Vieira, JD; Nascimento-Costa, JMIntrodução: A hipovitaminose D (hipoD) é uma carência vitamínica cada vez mais frequente nos países desenvolvidos, devido não só a erros alimentares, mas também à pouca exposição solar e ao sedentarismo. Objectivo: Determinar a prevalência de hipoD em doentes internados num Serviço de Medicina Interna e identificar possíveis variáveis associadas. Método: Estudo transversal e observacional onde foram incluídos 123 doentes internados, no período de Abril e Maio. Foram determinados os níveis séricos de vitamina D [25-hidroxivitamina D, 25(OH)D] e subdividida a amostra em três grupos com base nos níveis da 25(OH)D: hipoD grave (<10 ng/mL); hipoD moderada (>10 ng/mL e <20 ng/mL) e um terceiro grupo com níveis adequados de 25(OH) D (>20 ng/mL). Foram registadas variáveis demográficas e factores potencialmente relacionados com a deficiência de vitamina D. Resultados: Nesta amostra de doentes (52,0% mulheres) a média das idades foi 71±17 anos; 67,5% dos indivíduos apresentavam hipoD grave; 25,2% hipoD moderada e 7,3% níveis normais de vitamina D. Os doentes do grupo com hipoD grave eram mais idosos (p=0,027). O mesmo grupo apresentava um maior número de doentes acamados (p=0,022), índices funcionais mais elevados (p=0,009) e maior percentagem de indivíduos com IRC (p=0,011). A análise multivariada com aplicação de modelo de regressão logística revelou que as variáveis associadas a uma probabilidade aumentada de desenvolver hipoD grave foram: consumo de diuréticos (furosemida) [OR=3,673 (1,232-10,956) p=0,020] e a albumina ≤3,25 [OR=5,617 (2,257-13,981) p<0,001]. Conclusão: A elevada prevalência de hipoD grave (67,5%) neste grupo de doentes, alerta para a necessidade da determinação e monitorização das concentrações plasmáticas de 25(OH)D, de modo a iniciar tratamento precoce nos doentes com níveis insuficientes. Os doentes que apresentam consumo de furosemida e a hipoalbuminemia têm uma probabilidade aumentada de desenvolver hipoD grave. O tratamento desta hipovitaminose justifica-se não só pelo conhecimento das consequências clínicas relacionadas com a perda de massa óssea, mas também pela sua associação com a hipoalbuminemia que é um marcador de risco de mau prognóstico em doentes internados.
