- Anti-Signal Recognition Particle Myopathy in a Geriatric PatientPublication . Ferreira, DM; Mendes, PA; Aragão, A; Veríssimo, T; Carvalho, AAnti-signal recognition particle (SRP) myopathy is a rare idiopathic inflammatory myositis that usually affects middle-age women, and is characterized by rapidly progressive proximal and symmetrical muscle weakness, elevated creatine kinase levels, severe necrotizing immune-mediated myopathy, presence of anti-SRP autoantibodies and poor response to steroid therapy. We report a geriatric case of a previously independent patient, presenting with slow onset of proximal paraparesis, myalgia and severe gait impairment. The patient was treated with steroid and azathioprine, with laboratory and pain response but modest muscle strength improvement. The clinical presentation of this unusual patient was atypical, which hampered the correct diagnosis.
- Hypertriglyceridemic Pancreatitis: Conventional Treatment Versus Therapeutic Plasma ExchangePublication . Ferreira, DM; Lobo, F; Fonseca, JP; Mendes, PA; Aragão, A; Ferreira, M; Tomáz, J; Ferreira, M; Carvalho, AIntroduction: Acute pancreatitis (AP) induced by hypertriglyceridemia (HTG) can be treated with therapeutic plasma exchange (TPE), resulting in rapid reduction of triglyceride level. However, there are no definitive comparative studies that prove the real benefits of this therapy. Objectives: Comparison of treatment methods (TPE versus conventional) in patients with HTG AP during a period of 12 years (2000-2012). Methods: Retrospective, descriptive and inferential analysis of 37 patients, evaluating: gender, age, personal pathologic history, severity of disease, HTG values and evolution depending on treatment with therapeutic plasma exchange (“TPE”) or with conventional therapy (“C”). Results: Both groups TPE and C demonstrated homogeneity considering gender (p = 0.647), age (43.5 ± 9.74 years TPE vs 45.30 ± 9.90 years C; p = 0.320), prior AP episode (40% TPE vs 40.7% C; p = 1.0), chronic alcohol consumption (50% TPE vs 70.4% C; p = 0.275) and severity disease scores: APACHE II (p = 0.054) and Ranson (p = 0.258). More than one secondary HTG risk factor was presented in 45.95% of patients . TPE group presented higher TG levels at admission: 4850 ± 2802 mg/dL vs 1845 ± 1858 mg/dL (p = 0.001). No significant statistical differences were observed considering length of hospital stay [14.2 ± 6.8 days vs 13.5 ± 9.0 days (p = 0.56)] or mortality rate (p = 0.47). At discharge, TG reduction was greater in TPE group: 4433.70 ± 2896.08 mg/dL – 91.41% vs 1582.95 ± 2051.06 mg/dL – 83,92% (p = 0.002). Six minor complications associated to TPE occurred. Discussion/Conclusion: Despite the selection bias (retrospective study), a greater TG reduction was observed with TPE technique. Complications associated with the technique were simple to resolve
- Pancreatite Hipertrigliceridémica: Tratamento Convencional Versus Troca Plasmática TerapêuticaPublication . Ferreira, DM; Lobo, F; Fonseca, JP; Mendes, PA; Aragão, A; Ferreira, M; Tomaz, J; Carvalho, AIntrodução:A pancreatite aguda (PA) por hipertrigliceridemia (HTG) pode ser tratada com troca plasmática terapêutica (TPT), com redução rápida dos valores de triglicerídeos. Contudo, não existem estudos comparativos definitivos que comprovem o real benefício desta terapêutica. Objetivo: Comparação dos métodos de tratamento (troca plasmática terapêutica versus convencional) em doentes com PA HTG, durante um período de 12 anos (2000-2012). Métodos: Estudo retrospetivo descritivo e inferencial de 37 doentes, avaliando: sexo, idade, antecedentes pessoais, gravidade, valores de TG e evolução consoante o tratamento (“TPT” ou terapêutica convencional “C”). Resultados: Os dois grupos TPT e C mostraram-se homogéneos quanto ao sexo (p = 0,647), idade (43,5 ± 9,74 anos TPT versus 45,30 ± 9,90 anos C; p = 0.320), pancreatite prévia (40% TPT vs 40,7% C; p = 1,0) alcoolismo crónico (50% TPT vs 70,4% C; p = 0,275) e gravidade pelo score de APACHE II (p = 0,054) e Ranson às 48 horas (p = 0,258). Dos doentes 45,95% apresentava mais de um fator de risco secundário para HTG. O grupo TPT apresentou maiores valores de TG à admissão: 4850 ± 2802 mg/dL vs 1845 ± 1858 mg/dL (p = 0,001). Não se verificaram diferenças na duração do internamento 14,2 ± 6,8 dias vs 13,5 ± 9,0 dias (p = 0,56) ou na taxa de mortalidade (p = 0,47). À data de alta a redução dos TG foi superior no grupo TPT: 4433,70 ± 2896,08 mg/dL - 91,41% vs 1582,95 ± 2051,06 mg/dL – 83,92% (p = 0,002). De referir seis intercorrências minor durante a troca plasmática terapêutica. Discussão/Conclusões: Apesar do viés de seleção (estudo retrospetivo), foi constatada uma maior redução dos TG por esta técnica. As intercorrências inerentes à técnica de troca plasmática terapêutica foram de simples resolução.
