Nephrotic Range Proteinuria in Renal Transplantation: Clinical and Histologic C...
Leal, R; Pinto, H; Galvão, A; Santos, L; Romãozinho, C; Macário, F; Alves, R; Pratas, J; Sousa, V; Marinho, C; Prado E Castro, L; Campos, M; Mota, AINTRODUCTION: There is a high incidence of nephrotic proteinuria in renal transplant recipients, which is an accurate predictor of graft loss. Despite this, its histologic correlates and prognostic implications are still not well characterized. We assessed the clinical and histological correlates of kidney transplantation patients with nephrotic range proteinuria. METHODS: We have retrospectively analyzed clini...
Fibrogenesis in Kidney Transplant: Dysfunction Progress Biomarkers
Costa, J S; Alves, R; Sousa, V; Marinho, C; Romãozinho, C; Santos, L; Macário, F; Pratas, J; Prado E Castro, L; Campos, M; Figueiredo, AFibrogenesis markers, such as alpha-actin (AA), CD163 (macrophages), and E-cadherin, have been studied as chronic kidney allograft injury (CAI) predictors, a major cause of allograft failure. OBJECTIVE: Investigate the value of these markers in predicting CAI and initiation of dialysis. MATERIALS AND METHODS: Retrospective analysis of 26 kidney allograft biopsies (from 22 patients with CAI) during 2 years, eval...
Polyomavirus Nephropathy: Ten-Year Experience
Costa, JS; Ferreira, E; Leal, R; Bota, N; Romãozinho, C; Sousa, V; Marinho, C; Santos, L; Macário, F; Alves, R; Pratas, J; Campos, M; Figueiredo, ABACKGROUND: Polyomavirus nephropathy (BKVN) is an important cause of chronic allograft dysfunction (CAD). Recipient determinants (male sex, white race, and older age), deceased donation, high-dose immunosuppression, diabetes, delayed graft function (DGF), cytomegalovirus infection, and acute rejection (AR) are risk factors. Reducing immunosuppression is the best strategy in BKVN. The objective of our study was ...
What Can We Do When All Collapses? Fatal Outcome of Collapsing Glomerulopathy a...
Pinto, H; Leal, R; Rodrigues, L; Santos, L; Romãozinho, C; Macário, F; Alves, R; Pratas, J; Sousa, V; Marinho, C; Prado E Castro, L; Costa, F; Campos, MNTRODUCTION: Collapsing glomerulopathy (CG) is a rare form of glomerular injury. Although commonly associated with human immunodeficiency virus (HIV) infection, it can occur in association with systemic lupus erythematosus (SLE). CASE REPORT: We present the case of a 50-year-old man, with chronic kidney disease secondary to focal and segmental glomerulosclerosis, who received a cadaveric kidney transplant in 20...
Correlation of Helicobacter pylori genotypes with gastric histopathology in the...
Almeida, N; Donato, MM; Romãozinho, JM; Luxo, C; Cardoso, O; Cipriano, MA; Marinho, C; Fernandes, A; Sofia, CBACKGROUND: Outcome of Helicobacter pylori (H. pylori) infection results from interaction of multiple variables including host, environmental and bacterial-associated virulence factors. AIM: This study aimed to investigate the correlation of cagA, cagE, vacA, iceA and babA2 genotypes with gastric histopathology and disease phenotype in the central region of a South-European country. METHODS: This prospective st...
Beyond Maastricht IV: are standard empiric triple therapies for Helicobacter py...
Almeida, N; Donato, MM; Romãozinho, JM; Luxo, C; Cardoso, O; Cipriano, MA; Marinho, C; Fernandes, A; Calhau, C; Sofia, CBACKGROUND: Empiric triple treatments for Helicobacter pylori (H. pylori) are increasingly unsuccessful. We evaluated factors associated with failure of these treatments in the central region of Portugal. METHODS: This single-center, prospective study included 154 patients with positive (13)C-urea breath test (UBT). Patients with no previous H. pylori treatments (Group A, n = 103) received pantoprazole 40 mg 2×...
Triple Therapy with High-Dose Proton-Pump Inhibitor, Amoxicillin, and Doxycycli...
Almeida, N; Romãozinho, JM; Donato, MM; Luxo, C; Cardoso, O; Cipriano, MA; Marinho, C; Sofia, CINTRODUCTION: Helicobacter pylori resistance to antibiotics is steadily increasing and multidrug-resistant strains are common and difficult to eliminate, mainly in countries where bismuth, tetracycline, furazolidone, and rifabutin are unavailable. AIM: To evaluate the efficacy and safety of a triple therapy with proton-pump inhibitor (PPI), amoxicillin, and doxycycline in patients with multidrug-resistant H. py...
Tumor de células de Leydig do ovário: caso clínico
Saleiro, S; Gonçalves, S; Marinho, C; Rebelo, T; Manarte, A; Oliveira, CFLeydig cell tumours account for 0.1% of all ovarian tumours and are a type of steroid cell tumour. According to the World Health Organisation they are classified in the group of sex cord stromal tumours. The clinical presentation is usually a hyperandrogenic state with signs of virilisation, but occasionally patients may exhibit a hyperestrogenic state. The tumour has a benign behaviour, with an excellent progn...
