Propylthiouracil Induced Pulmonary-Renal Syndrome: a Case Report.

Propylthiouracil (PTU) is known to induce antineutrophil cytoplasmatic antibody (ANCA) seropositivity; however, small vessel vasculitis (SVV) with pulmonary and renal involvement is rare. We present the case of an 81-year-old woman on PTU treatment due to toxic nodular goitre who developed alveolar hemorrhage and rapidly progressive glomerulonephritis. The authors highlight the importance of early recognising drug-induced pulmonary-renal syndrome (PRS) in order to avoid unnecessary tests, a delay in the diagnosis and evolution to end-stage kidney disease or life-threatening conditions.

Renal Transplantation in HIV-Infected Patients: The First Portuguese Review

INTRODUCTION: With the introduction of combination antiretroviral therapy (cART), prognosis of human immunodeficiency virus (HIV) infection has been improved and kidney transplantation (KT) in HIV-positive patients became possible. METHODS: We reviewed the demographic, clinical, laboratory, and therapeutic data of all the HIV-infected patients who underwent KT between 2009 (first KT in Portugal in a HIV-infected patient) and May 2014. Case accrual was through all Portuguese KT centers where a KT in an HIV-infected patient was performed. Patients were transplanted following the American and Spanish guideline recommendations that included maintenance on cART, undetectable plasma HIV RNA copies, and absolute CD4 counts of ≥ 200 cells/μL in the last 6 months. RESULTS: Fourteen KT were performed on men and 3 on women. The mean age of patients at the time of transplantation was 49.9 ± 11.7 years. HIV status was known for 12 ± 5 years. Eight patients had AIDS in the past and all patients received grafts from deceased donors. Twelve patients (64.7%) underwent induction therapy with basiliximab and 2 patients experienced early graft loss. In 2 patients, humoral rejection was diagnosed and in 3 patients, cellular rejection. Two patients died and an additional patient had early graft loss. CONCLUSION: KT is a possible, but challenging, renal replacement therapy in selected HIV-positive patients. Even in those with AIDS criteria in the past, when the disease is controlled, and after the reconstitution of the immune system with cART, KT can be performed. Nevertheless, the risk-benefit ratio for each patient needs to be taken in consideration.

Hemangioma Cavernoso da Supra-Renal

INTRODUÇÃO: O hemangioma cavernoso da glândula supra-renal é um tumor benigno, raro, com menos de uma centena de casos reportados na literatura. É caracterizado na sua constituição por formações vasculares dilatadas e delimitadas por células endoteliais. Apresenta-se caracteristicamente como um incidentaloma e o seu diagnóstico é habitualmente estabelecido apenas no pós-operatório. CASO CLÍNICO: Doente de 73 anos referenciada por nódulo de 45mm da glândula supra-renal esquerda diagnosticado incidentalmente no seguimento de lesão quística renal. A avaliação imagiológica por TC revelou nódulo sólido de 45x28mm na glândula supra-renal esquerda. Realizou estudo para avaliar a autonomia do nódulo, e que revelou uma hipersecreção adrenérgica. Colocada a hipótese diagnóstica de feocromocitoma e proposta para cirurgia ablativa. Foi submetida a suprarrenalectomia esquerda laparoscópica, que decorreu sem intercorrências. O resultado histológico da peça operatória revelou um hemangioma cavernoso da supra-renal. DISCUSSÃO / CONCLUSÃO: A forma de apresentação mais comum do hemangioma cavernoso da supra-renal é a de um incidentaloma, implicando o diagnóstico diferencial com os vários tipos de lesões ocupando espaço deste órgão. Este facto associado à falta de especificidade dos exames pré-operatórios e à raridade da patologia compromete a acuidade diagnóstica. No presente caso, assim como na maioria dos reportados na literatura, esta patologia foi somente estabelecida no pós-operatório através do resultado anátomo-patológico.
