- Atypical renal presentation of antiphospholipid syndromePublication . Gaspar, A; Manso, RT; Pereira, F; Cunha, L; Inchaustegui, L; Serra, A; Rodrigues, B; Correia, PAntiphospholipid syndrome (APS) is a systemic autoimmune disease which can occur as a primary disease or in association with other autoimmune diseases, the most frequent being Systemic Lupus Erythematosus (SLE). Although renal manifestations of SLE are well known, antiphospholipid syndrome renal manifestations such as antiphospholipid syndrome nephropathy and glomerulopathies have yet to be better characterized. The authors present the case of a 39 -year -old Caucasian woman with antiphospholipid syndrome diagnosis and a previous history of deep venous thrombosis and intermittent polyarthralgia, who was referred to a nephrology consultation for proteinuria and microscopic haematuria with preserved renal function. The renal biopsy showed a pattern of membranous glomerulopathy and thrombotic microangiopathy in association with antiphospholipid syndrome nephropathy. This case report illustrates a complex clinical and anatomopathological case of a 39 - year -old woman with a previous antiphospholipid syndrome diagnosis who presented with unspecific manifestations such as proteinuria and microscopic haematuria and preserved renal function. The histological findings alert us to the range of possible renal manifestations of APS and the need to better characterize these patients by preforming renal biopsy.

- Severe Systemic Lupus Erythematosus presentation in patient with alternative complement pathway mutationsPublication . Pereira, F; Cunha, L; Campos, P; Gaspar, A; Manso, RT; Soto, KSystemic lupus erythematosus (SLE) is an autoimmune disease which can involve almost any organ, making its difficult therapeutic approach. Immune complex deposition can often activate complement, accounting for many of SLE clinical manifestations and laboratory findings. We present a case of a patient who presented with acute pancreatitis and acute kidney injury as onset manifestations of SLE, later developing neurological manifestations, who was successfully treated with rituximab, plasma exchange and steroids as induction therapy. Persistently low C3 level led to a genetic analysis of the complement system components. We found three polymorphisms in the alternative pathway of complement regulators (complement factor H c2669 G>T, p.Ser890Ile and c3019 G>T, p.Val1007Leu and complement factor I c.482+6 G>T), two of which have been correlated with atypical haemolytic uraemic syndrome and dense deposit disease and also complement factor H -related protein (CFHR1 and CFHR3) mutations by deletion. This raises the question whether these polymorphisms and mutations played any role in our patient’s clinical course.
- Therapeutic plasma exchange in patients in a portuguese ICUPublication . Calça, R; Gaspar, A; Santos, A; Aufico, A; Freitas, PT; Coelho, SPurpose: The aim of this study is to characterize a Portuguese Intensive Care Unit experience in therapeutic plasma exchange in critically ill patients. Methods: We performed a retrospective analysis of the patients treated with therapeutic plasma exchange between 2000 and 2019. Data on patient characteristics, therapeutic plasma exchange prescription, adjuvant therapy used, adverse events and outcome under treatment were collected. Results: A total of 101 therapeutic plasma exchange procedures in 20 patients were studied. Mean number of therapeutic plasma exchange sessions per patient was 5.1±1.3. The most frequent indications to begin this treatment were myasthenia gravis (25.0%) and anti -neutrophil -cytoplasmic antibody -associated vasculitis (15.0%). There were 45.5% adverse events and the most frequent was hypotension (15.2%). 98% of the complications were mild -to -moderate. The outcome was favorable in 60.0% of patients. Conclusion: Therapeutic plasma exchange is an effective and safe therapy in many diseases that had high morbidity and mortality prior to the use of this technique.
- Tirosinemia Tipo 1: O Passado e o Presente Numa Unidade de Doenças MetabólicasPublication . Oliveira, J; Rodrigues, M; Costa, C; Janeiro, P; Almeida, I; Vilarinho, L; Gaspar, AIntrodução: A ti rosinemia ti po I é uma doença hereditária do metabolismo por défi ce de fumarilacetoacetase, com uma pre- valência ao nascimento de 1:100000 e potencialmente fatal. O plano alimentar individualizado, o transplante hepato-renal e a niti sinona são algumas das estratégias terapêuti cas. Métodos: Estudo retrospeti vo, observacional e descriti vo de oito doentes acompanhados numa unidade de doenças meta- bólicas, entre janeiro de 1981 e dezembro de 2012. Analisaram-se dados demográfi cos, manifestações clínicas, terapêuti ca, evolução clínica e laboratorial. Resultados: Na década de 80 do século passado foram diagnosti cados quatro doentes, dos quais dois faleceram em contexto de insufi ciência hepáti ca e carcinoma hepatocelular, uma doente foi submeti da a transplante hepáti co e outra a transplante hepato-renal. Ambas estão clinicamente bem, mantendo terapêuti ca imunossupressora. Na década seguinte foram diagnos- ti cados dois doentes, dos quais um faleceu aos 3 meses por insufi ciência hepáti ca aguda e carcinoma hepatocelular. A outra doente iniciou terapêuti ca com niti sinona e plano alimentar personalizado, com boa evolução clínica e laboratorial até à ado- lescência, altura em que surgiram difi culdades escolares e de controlo metabólico, possivelmente relacionadas com períodos de incumprimento dietéti co. O rastreio metabólico neonatal alargado permiti u diagnosti car dois doentes às 3 semanas de vida em fase pré-sintomáti ca. Estes iniciaram plano alimentar personalizado e niti sinona e mantêm bom controlo metabólico e desenvolvimento psicomotor adequado. Discussão: A possibilidade de diagnósti co precoce e uti lização da niti sinona revolucionaram o prognósti co dos doentes com ti rosinemia ti po 1. O risco de carcinoma hepatocelular e outras complicações implicam vigilância clínica, laboratorial e imagio- lógica regular.
