Abdominal Wall Hernias in Peritoneal Dialysis Patients: Risk Factors and Techni...
Alferes,Daniela; Almeida,Catarina; Faria,Vitória; Dias,Joana; Carmo,Rute; Lopes,Daniela; Fernandes,João Carlos; Almeida,Clara; Gomes,Ana MartaABSTRACT Introduction: Peritoneal dialysis patients are at increased risk of developing abdominal wall complications, including hernias. This study aimed to determine the incidence of hernias in peritoneal dialysis patients, identify risk factors, and evaluate their impact on technique survival. Methods: A retrospective cohort study was conducted, including prevalent peritoneal dialysis patients in a single cen...
A New Approach for Histamine Functionalized Nanoparticles as Sorbent Phase for ...
Lopes,Daniela; Morés,Lucas; Bernardi,Gabrieli; Campedelli,Roberta R.; Pinheiro,Gabriela; Souza,Bruno S. de; Carasek,EduardoIn this study, for the first time, histamine-functionalized magnetic nanoparticles (HIS-MNP) were used as sorbent phase combined with bar adsorptive microextraction (BAµE) for the determination of methylparaben (MP), ethylparaben (EP), propylparaben (PP), and butylparaben (BP) in water samples by high performance liquid chromatography coupled with diode array detection (HPLC-DAD). Extraction and desorption cond...
Encapsulating peritoneal sclerosis: from early diagnosis to successful kidney t...
Reis,Marina; Gomes,Ana Marta; Santos,Clara; Lopes,Daniela; Fernandes,João CarlosAbstract Encapsulating peritoneal sclerosis is an uncommon but serious complication of peritoneal dialysis. In most cases, the symptoms appear after peritoneal dialysis withdrawal, which hampers its diagnosis. We present the case of a 44-years-old Caucasian male who had been on peritoneal dialysis for 6 years and 3 months and was switched to hemodialysis due to ultrafiltration failure. During his last months on...
Is COVID-19 that different in hemodialysis patients?: A single-center experience
Reis,Marina; Almeida,Catarina; Ventura,Ana; Ribeiro,Catarina; Gomes,Ana Marta; Lopes,Daniela; Santos,Clara; Sousa,Sónia; Fernandes,João CarlosABSTRACT Coronavirus disease 2019 (COVID-19) has affected millions worldwide, and in particular the care of patients on maintenance hemodialysis. These patients are thought to be at high risk of severe SARS-CoV-2 infection due to their older age and multiple comorbidities. The aim of this study was to compare hemodialysis and non-dialysis COVID-19 patients and find possible risk factors for mortality in hemodia...
Cerebral vasculitis - a rare presentation of antineutrophil cytoplasmic antibod...
Rodrigues,Sara Daniela; Ventura,Ana Maria; Lopes,Daniela; Pereira,Susana; Almeida,Maria Clara; Gomes,Ana Marta; Fernandes,João CarlosAntineutrophil cytoplasmic antibody (ANCA) associated vasculitis commonly involves kidney, lung, upper respiratory tract, skin, gastrointestinal and occasionally peripheral nervous system. Central nervous system is less commonly affected and is generally part of a multi-organ scenario. We present a case of a 21-year-old female with chronic kidney disease secondary to myeloperoxidase ANCA associated vasculitis, ...
Survival of hemodialysis patients: A new reality?
Belino,Carolina; Coelho,Augusto; Pereira,Susana; Lopes,Daniela; Gomes,Ana Marta; Ventura,AnaIntroduction: Survival rates of haemodialysis patients have increased worldwide over the last decade. The purposes of this study were to analyze the 10-year survival rate and to identify mortality risk factors in a Portuguese cohort. Subjects and Methods: Data was collected from 273 incident patients on facility haemodialysis treatments between 2005 and 2015. Sociodemographic data, medical history, clinical and...
A rare case of cutaneous involvement in atypical haemolytic uraemic syndrome su...
Lopes,Daniela; Gomes,Ana Marta; Cunha,Cátia; Pereira,Susana; Tente,David; Fernandes,João CarlosAtypical haemolytic uraemic syndrome (aHUS) is a rare, life-threatening, genetic disease, due to uncontrolled alternative pathway complement activation. Although the renal microvasculature appears to be the predominantly affected target, other organ pathology compatible with local thrombotic microangiopathy has been reported. Eculizumab is a humanized antibody therapy that has been associated with significant i...
Idiopathic nodular glomerulosclerosis: a case report
Cunha,Catia; Gomes,Ana Marta; Lopes,Daniela; Sousa,Sonia; Pereira,Susana; Campelos,Sofia; Tente,David; Fernandes,Joao CarlosThe histological pattern of nodular glomerulosclerosis is typical of diabetic nephropathy, but it can be found in other diseases, such as chronic membranoproliferative glomerulonephritis, amyloidosis, monoclonal immunoglobulin deposition and fibrillary/immunotactoid glomerulopathies. Additionally, there are few reports of idiopathic nodular glomerulosclerosis, an exclusion diagnosis, which has been associated w...
Renal Involvement in Multiple Myeloma: an experience of a single centre
Santos,Clara; Lopes,Daniela; Barreto,Patricia; Cunha,Catia; Gomes,Ana Marta; Ventura,Ana; Coelho,Henrique; Seabra,JoaquimIntroduction: Multiple myeloma is a plasma cell dyscrasia that accounts for almost 10% of all haematologic malignancies. It often presents with acute kidney injury that has long been associated with a poor prognosis. It is important to recognize markers of poor prognosis to promote an early and aggressive management of the disease, to improve disease outcomes. Subjects and Methods: We have, therefore, investiga...
