Thrombotic microangiopathy triggered by podocytopathy.

Thrombotic microangiopathy (TMA) is a rare group of diseases characterized by microangiopathic hemolytic anemia, thrombocytopenia, and target organ damage. It can be divided into primary and secondary TMA. Herein we report a case of TMA associated to a primary glomerular disease. We report the case of a 31-year-old Black male from Cape Verde admitted in March 2018 with nephrotic syndrome and upper gastrointestinal bleeding, the latter due to severe erythematous gastritis. He was discharged after clinical stabilization. The patient came to Portugal 8 months later. On admission, he presented with rapid deterioration of kidney function and hyperkalemia. The etiologic study revealed microangiopathic hemolytic anemia, nephrotic syndrome and microscopic hematuria. Immunologic study and viral serology were negative. ADAMTS13 activity and inhibitor testing were within normal range, genetic complement evaluation showed CFH-H3 in homozygosity, functional complement studies revealed decreased function of alternative pathway. Kidney biopsy was consistent with the diagnosis of TMA, and electron microscopy was compatible with minimal change disease. Patient underwent plasmapheresis with resolution of hemolysis, fluid overload and recovery of renal function. Two months later, he presented with nephrotic syndrome and started prednisolone with remission. Six months later, the nephrotic syndrome relapsed, and it became steroid-, MMF-, and rituximab-resistant. Tacrolimus was initiated, achieving partial remission. Atypical hemolytic uremic syndrome is an uncommon disease and is rarely reported as secondary to glomerular diseases. This case showcases the challenges regarding treatment options in a resistant glomerulopathy and the implications of therapeutic choices and kidney outcomes with the coexisting TMA.

Unexpected success in early post-transplantation renal vein thrombosis: A case report and literature review.

BACKGROUND: Allograft renal vein thrombosis can cause graft loss during the early postoperative period. This diagnosis is sometimes elusive, requiring a strong suspicion. On the other hand, several authors have recognized risk factors for allograft renal vein thrombosis, but neither a preventive approach nor a treatment have been recommended for this complication. CASE PRESENTATION: We present a case report of early allograft renal vein thrombosis, preceded by femoral common deep vein thrombosis in a recipient of a third kidney transplant. Despite femoral common deep vein thrombosis treatment with low-molecular-weight heparin and progressive improvement of renal function to a nadir serum creatinine of 0.51 mg/dL, the patient experienced a sudden episode of anuria on postoperative day 5. Doppler ultrasonography strongly suggested the diagnosis of allograft renal vein thrombosis. The patient underwent balloon catheter and aspiration venous thrombectomy, followed by unfractionated heparin perfusion. After 4 days of anuria and multiple blood transfusions, when allograft nephrectomy was contemplated, diuresis suddenly resumed. After 1 year of follow-up, the patient still has a normal renal function. CONCLUSION: This case report shows successful treatment of allograft renal vein thrombosis associated with deep vein thrombosis in the first week of transplantation, using balloon catheter and aspiration venous thrombectomy followed by perfusion of unfractionated heparin. The authors suggest this technique as a treatment option for transplant renal vein thrombosis. However, they reinforce the importance of individualized treatment and they remind that a delay may jeopardize the potential benefit of the procedure.

Kinetics of torquetenovirus DNA load in a recent kidney transplant recipient with mild SARS-CoV-2 infection and a failed antibody response.

Kidney transplant (KT) recipients are at an increased risk for severe COVID-19 because of their immunosuppressed state. A 42-year-old KT patient was diagnosed with COVID-19 three months after KT. Despite lymphopenia and several risk factors, he had a mild disease course. Nasopharyngeal real-time reverse transcriptase polymerase chain reaction for SARS-CoV-2 became negative 48 days after detection. SARS-CoV-2 IgG antibodies became negative after day 40. TTV DNA load increased with the onset COVID-19 and reduced after its resolution. This is the first report where TTV DNA load was measured during the course of COVID-19.

High-grade urothelial carcinoma in a kidney transplant recipient after JC virus nephropathy: The first evidence of JC virus as a potential oncovirus in bladder cancer.

Kidney transplant (KT) recipients have an increased risk for urothelial carcinoma. A role for JC virus (JCV) in human cancers is not yet proved but there is an increasingly reported association between BK virus (BKV) nephropathy and renourinary neoplasms. We report a KT recipient who developed a high-grade urothelial carcinoma 5 years after a diagnosis of JCV nephropathy and 9 years after kidney transplantation. Neoplastic tissue was positive for JCV DNA by real-time polymerase chain reaction (PCR). Immunochemical staining showed strong positivity for cell cycle markers (p16, p53, and Ki67) and for early viral protein JCV large T antigen (JCV LTag; using a broad polyomavirus antibody); however, late viral protein (VP1) stained negative. In contrast, in non-neoplastic urothelium, JCV DNA and all immunochemical markers were negative. These facts suggest that malignancy was induced by JCV. To the best of our knowledge, this is the first report of urothelial high-grade carcinoma associated with JCV nephropathy in a KT recipient.

Impact of Transcatheter Aortic Valve Implantation on Kidney Function / Impacto do Implante Percutâneo de Válvula Aórtica na Função Renal

Abstract Background: Chronic kidney disease (CKD) is frequently present in patients with aortic valve disease. Decreased kidney perfusion as a consequence of reduced cardiac output may contribute to renal dysfunction in this setting. Objective: Given the potential reversibility of kidney hypoperfusion after valve repair, this study aimed to analyze the impact of percutaneous transcatheter aortic valve implantation (TAVI) on kidney function. Methods: We performed a retrospective analysis of 233 consecutive patients who underwent TAVI in a single center between November 2008 and May 2016. We assessed three groups according to their baseline estimated glomerular filtration rate (eGFR) (mL/min/1.73 m2): Group 1 with eGFR ≥ 60; Group 2 with 30 ≤ eGFR < 60; and Group 3 with eGFR < 30. We analyzed the eGFR one month and one year after TAVI in these three groups, using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula to calculate it. Results: Patients from Group 1 had a progressive decline in eGFR one year after the TAVI procedure (p < 0.001 vs. pre-TAVI). In Group 2 patients, the mean eGFR increased one month after TAVI and continued to grow after one year (p = 0.001 vs. pre-TAVI). The same occurred in Group 3, with the mean eGFR increasing from 24.4 ± 5.1 mL/min/1.73 m2 before TAVI to 38.4 ± 18.8 mL/min/1.73 m2 one year after TAVI (p = 0.012). Conclusions: For patients with moderate-to-severe CKD, kidney function improved one year after the TAVI procedure. This outcome is probably due to better kidney perfusion post-procedure. We believe that when evaluating patients that might need TAVI, this 'reversibility of CKD effect' should be considered.

Resumo Fundamento: Pacientes com doença valvar aórtica frequentemente apresentam doença renal crônica (DRC). Diminuição da perfusão renal como consequência da redução do débito cardíaco pode contribuir para a disfunção renal neste cenário. Objetivo: Dado o potencial de reversibilidade da hipoperfusão renal após o reparo valvar, este estudo teve o objetivo de analisar o impacto do implante percutâneo de válvula aórtica (TAVI - transcatheter aortic valve implantation) na função renal. Métodos: Foi realizada uma análise retrospectiva de 233 pacientes consecutivos submetidos ao TAVI em um único centro, entre novembro de 2008 e maio de 2016. Três grupos foram avaliados de acordo com a taxa de filtração glomerular estimada (TFGe) basal (mL/min/1,73 m2): Grupo 1 com TFGe ≥ 60; Grupo 2 com 30 ≤ TFGe < 60; e Grupo 3 com TFGe < 30. O TFGe foi analisado nestes três grupos um mês e um ano após o TAVI e calculado usando a fórmula do Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI). Resultados: Os pacientes do Grupo 1 tiveram um declínio progressivo da TFGe um ano após o procedimento TAVI (p < 0,001 vs. pré-TAVI). Nos pacientes do Grupo 2, a média da TFGe aumentou um mês depois do TAVI e continuou crescendo depois de um ano (p = 0,001 vs. pré-TAVI). O mesmo ocorreu no Grupo 3, com a média da TFGe subindo de 24,4 ± 5,1 mL/min/1,73 m2 antes do TAVI para 38,4 ± 18,8 mL/min/1,73 m2 um ano após o TAVI (p = 0,012). Conclusões: Em pacientes com DRC moderada a grave, a função renal melhorou um ano após o procedimento TAVI. Este resultado é provavelmente devido à melhora da perfusão renal pós-procedimento. Acredita-se que, ao avaliar pacientes que possam precisar de TAVI, este 'efeito de reversibilidade da DRC' deva ser considerado.

Sexual Dysfunction and Satisfaction in Kidney Transplant Patients.

INTRODUCTION: 10% of the world's population suffers from chronic kidney disease. Kidney transplants provide an improvement in the quality of life of those patients. Sexual dysfunction is common after kidney transplantation, and its etiology is presumed to be multifactorial. It has a negative impact on sexual satisfaction and health-related quality-of-life. The integration of a new organ into the body can imply an adjustment of body image, which may eventually have a negative influence on intimacy and sexual behaviors. AIM: To evaluate male sexual function, sexual satisfaction, and body image satisfaction among a convenience sample of patients who have had a kidney transplant. METHODS: This is a cross-sectional study that included 460 patients, from a single healthcare center, who had undergone a kidney transplant procedure >4 weeks ago. A total of 112 respondents (mean = 55.5 years, SD = 11.4) answered the questionnaires properly. MAIN OUTCOME MEASURES: All recruited patients answered a self-reported sociodemographic questionnaire, in addition to the International Index of Erectile function, the New Scale of Sexual Satisfaction, the Brief Symptom Inventory, and the Body Image Scale. RESULTS: A correlation was found between sexual function and sexual satisfaction (r = 0.598, P < .001, n = 112), as well as between body image satisfaction and sexual function (r = -0.193, P = .042, n = 112). The length of time after a kidney transplant (≤ or >36 months) was not associated with a difference in sexual functioning or sexual satisfaction. CLINICAL IMPLICATIONS: This study showed the obvious implications of sexual function on sexual satisfaction, which should alert healthcare professionals to the importance of identifying and managing sexual dysfunction in patients with chronic kidney disease, to optimize their global and sexual health satisfaction. STRENGTH & LIMITATIONS: This study identified a high prevalence of sexual dysfunction among kidney transplant recipients. This should reinforce the need for the medical community to evaluate the quality-of-life domains of patients with chronic disease. There is still a lack of information concerning any longitudinal evaluation of kidney transplant patients' sexual function and the effects that this surgery has on sexuality. CONCLUSIONS: This study corroborated the severe effects that kidney transplant patients often report regarding their sexuality. Among the patients who participated in the study, sexual function proved to be relevant in relation to sexual satisfaction. Mota RL, Fonseca R, Santos JC, et al.

The impact of functioning hemodialysis arteriovenous accesses on renal graft perfusion: Results of a pilot study.

INTRODUCTION: After a kidney transplant, it is unknown whether the maintenance of a functioning hemodialysis arteriovenous access could have deleterious effects on renal grafts. We hypothesize that maintaining an arteriovenous access can deviate a significant proportion of the cardiac output from the renal graft. The aim of this study was to investigate whether a temporary closure of the arteriovenous access could lead to an increase in graft perfusion. METHODS: We conducted a study in 17 kidney-transplanted patients with a functioning arteriovenous access. We evaluated, at baseline and 30 s after compression of the arteriovenous access (access flow occlusion), the hemodynamic parameters and the renal resistive index of the graft by Doppler ultrasound. RESULTS: After arteriovenous access occlusion 82.4% (n = 14) of the patients had a decrease in resistive index. All patients had a decrease in heart rate (67 vs 58 bpm, p < 0.001) and 14 (82.4%) had an increase in mean blood pressure (98.3 vs 101.7 mm Hg, p = 0.044). There was a significant decrease in the resistive index (ΔRI) after the access occlusion (0.68 vs 0.64, p = 0.030). We found a negative correlation in Qa (r2 = -0.55, p = 0.022) with the ΔRI, and Qa was an independent predictor of ΔRI in a model adjusted to pre-occlusion resistive index. CONCLUSION: Our results showed that temporary occlusion of an arteriovenous access causes a significant decline in renal graft resistive index and this decline is higher with the occlusion of accesses with higher Qa. These results suggest that the maintenance of arteriovenous accesses, mainly those with higher Qa, can decrease renal graft perfusion.

Risk of hepatitis B reactivation in hepatitis B surface antigen seronegative and core antibody seropositive kidney transplant recipients.

BACKGROUND: Previous contact with Hepatitis B virus (HBV) is common in patients undergoing hemodialysis. Literature has shown conflicting results on the risk of HBV reactivation in kidney transplant (KT) recipients with serologic evidence of past HBV infection. METHODS: We reviewed 631 consecutive KT recipients and selected 70 patients simultaneously HBsAg negative and anti-HBc positive before KT, regardless of hepatitis B surface antibody (anti-HBs) status. Demographic characteristics, coinfection with other viruses, the presence of a previous KT, induction and maintenance immunosuppression, length of follow up, biopsy-proven acute rejection episodes, incidence of impaired liver function, and causes of graft loss and mortality were collected. Hepatitis B virus reactivation was defined as detection of HBV DNA viral load >2000 IU/mL during follow up. Outcome data included HBV reactivation episodes, graft function, and patient survival. RESULTS: Median follow-up was 151 months; 91.4% of patients were positive to anti-HBs prior to KT. No patient received HBV prophylaxis and 11 patients (15.7%) received rituximab as part of induction therapy. Anti-HBs titers remained stable in all patients throughout the observation period but two patient showed evidence of HBV reactivation after KT. CONCLUSION: Hepatitis B virus reactivation in HBsAg-negative and anti-HBc-positive after KT is rare but possible. We suggest evaluating HBV serologies, HBV DNA viral load, and liver enzymes before KT and routinely monitoring serologic HBV markers after KT. As only two patients experienced HBV reactivation, it is neither possible to define risk factors for HBV reactivation nor to evaluate the impact of different immunosuppressants or the benefit of prophylactic regimens. Further studies regarding HBV reactivation in solid organ transplant recipients are necessary.

Comparação da qualidade microbiológica de sanduíches comercializados em estabelecimentos do tipo fast food franqueados e não franqueados / Comparison of the microbiological quality of commercialized sandwiches in franchised and non-franked fast food establishments

Este trabalho objetivou comparar a qualidade microbiológica e higienicossanitáriade sanduíches comercializados por restaurantes do tipo fast food, franqueados e não-franqueados. Sanduíches de mesmo padrão foram adquiridos, sob a forma de consumidor, em 4 estabelecimentos franqueados e 4 não-franqueados, em três dias diferentes durante a semana, incluindo o final de semana. As temperaturas dos lanches foram aferidas no momento da compra e, em laboratório, as amostras foram analisadas para contagem de colônias e identificação das bactérias com os testes Enterokit B e Staphy Test da Probac do Brasil. Os estabelecimentos franqueados apresentaram mais sanduíches contaminados por coliformes fecais e S. aureus. Quanto à temperatura no momento da compra, por vários dias, ambos os tipos de estabelecimento não atenderam à legislação, apresentando valores inferiores a 60ºC, mas não houve diferença estatisticamente significante entre franqueados e não-franqueados. Estabelecimentos não-franqueados são mais contaminados, mas as lojas franqueadas também não conseguem colocar em prática o que a legislação preconiza para Boas Práticas higienicossanitárias.

This study aimed to compare the microbiological and sanitary conditions between sandwiches sold by fast food restaurants, franchised and nonfranchised. The same standard sandwiches were purchased by consumers on 4 franchised restaurants and 4 non-franchised, on three different days of the week, including the weekend. Temperatures were measured at the time of purchase, and in the laboratory, the samples were immersed in BHI broth and subsequently inoculated in Agar MacConkey, Agar Salmonella Shigella and Agar BairdParker for colony counting and identification of bacteria with Enterokit B and Staphy tests Test the Probac Brazil.The franchised outlets had more sandwiches contaminated by fecal coliforms and S.aureus. When it comes to temperature at the time of purchase, in several days, both types of establishment did not comply the legislation, presenting values inferior than 60° C, but there wasn't statistically significant difference between franchised and non-franchised. Nonfranchised outlets are more contaminated, but the franchised stores also fail to put into practice what the legislation proposes for Best Practice Sanitary Hygienic.

Gastrointestinal Bleeding and Diffuse Skin Thickening as Kaposi Sarcoma Clinical Presentation.

A 56-year-old African patient received a kidney from a deceased donor with 4 HLA mismatches in April 2013. He received immunosuppression with basiliximab, tacrolimus, mycophenolate mofetil, and prednisone. Immediate diuresis and a good allograft function were soon observed. Six months later, the serum creatinine level increased to 2.6 mg/dL. A renal allograft biopsy revealed interstitial fibrosis and tubular atrophy grade II. Toxicity of calcineurin inhibitor was assumed and, after a switch for everolimus, renal function improved. However, since March 2014, renal function progressively deteriorated. A second allograft biopsy showed no new lesions. Two months later, the patient was admitted due to anuria, haematochezia with anaemia, requiring 5 units of packed red blood cells, and diffuse skin thickening. Colonoscopy showed haemorrhagic patches in the colon and the rectum; histology diagnosis was Kaposi sarcoma (KS). A skin biopsy revealed cutaneous involvement of KS. Rapid clinical deterioration culminated in death in June 2014. This case is unusual as less than 20 cases of KS with gross gastrointestinal bleeding have been reported and only 6 cases had the referred bleeding originating in the lower gastrointestinal tract. So, KS should be considered in differential diagnosis of gastrointestinal bleeding in some kidney transplant patients.

[Urinary tract infections in a cohort of kidney transplant recipients]. / Infeções do trato urinário numa coorte de transplantados renais.

INTRODUCTION: Urinary tract infection is the most common infectious complication following renal transplantation and its frequency is insufficiently studied in Portugal. The aim of this study was to characterize the incidence of urinary tract infections and recurrent urinary tract infections in renal transplant recipients. MATERIAL AND METHODS: This was a retrospective cohort observational study, obtained from clinical files of all patients who received a renal transplant at the Hospital of Santa Cruz, from January 2004 to December 2005, with a mean follow-up period of five years or until date of graft loss, death or loss of follow-up. After a descriptive analysis of the population, we used bivariate tests to identify risk factors for urinary tract infections. RESULTS: A total of 127 patients were included, with a 593 patients.year follow-up. We detected 53 patients (41.7%) presenting with at least one episode of urinary tract infection; 21 patients (16.5%) had recurrent urinary tract infection. Female gender was the only risk factor associated with the occurrence of urinary tract infections (p < 0.001, OR = 7.08, RR = 2.95) and recurrent urinary tract infections (p < 0.001, OR = 4.66, RR = 2.83). Escherichia coli (51.6%), Klebsiella pneumoniae (15.5%) and Enterobacter spp (9.9%) were the most frequently identified pathogens. Patients did not reveal an increased mortality or allograft loss. However, urinary tract infections were the most important cause of hospital admissions. DISCUSSION: Female gender was the only risk factor for urinary tract infections in this population. Escherichia coli was the most frequent agent isolated. CONCLUSION: Despite preventive measures, urinary tract infections remain an important cause of morbidity and hospital admissions.

Introdução: A infeção do trato urinário é a complicação infeciosa mais comum no período pós transplante renal, estando a sua frequência pouco caracterizada na população portuguesa. Este trabalho teve como objetivo determinar a incidência de infeções do trato urinário e infeções do trato urinário recorrentes em transplantados renais. Material e Métodos: Tratou-se de um estudo observacional de coorte retrospetiva, com consulta dos processos clínicos de doentes transplantados entre Janeiro de 2004 e Dezembro de 2005, no Hospital de Santa Cruz, com seguimento durante cinco anos ou até à data de perda de enxerto, morte ou perda de follow-up. Após uma análise descritiva da população, utilizámos testes bivariados para identificação de fatores associados a infeções do trato urinário. Resultados: Em 127 doentes incluídos com seguimento de 593 doentes/ ano, 53 (41,7%) tiveram pelo menos um episódio de infeção do trato urinário e 21 (16,5%) tiveram infeções do trato urinário recorrentes. O género feminino foi o único fator associado com ocorrência de infeções do trato urinário (p < 0,001, OR = 7,08, RR = 2,95) e infeções do trato urinário recorrentes (p < 0,001, OR = 4,66, RR = 2,83). Os agentes etiológicos mais frequentes foram Escherichia coli (51,6%), Klebsiella pneumoniae (15,5%) e Enterobacter spp (9,9%). As infeções do trato urinário não causaram aumento de mortalidade ou perda de enxerto, mas foram a principal causa de internamentos hospitalares. Discussão: Na nossa população, apenas o género feminino foi identificado como fator de risco para o desenvolvimento de infeções do trato urinário, recorrentes ou não. Escherichia coli foi o agente etiológico mais frequente. Conclusão: Apesar das medidas preventivas adotadas, as infeções do trato urinário continuam a ser uma importante causa de morbilidade e de internamentos hospitalares.

Peripheral artery disease: a cause of refractory hypertension after renal transplantation.

The authors report the case of a 44-year-old man, with a history of hypertension, smoking, peripheral artery disease and chronic renal failure. After renal transplantation, the patient developed persistent high blood pressure, despite optimal medical therapy. When angiotensin-converting enzyme (ACE) inhibitor therapy was begun, he developed acute anuric renal failure, which was reversed after interruption of the ACE inhibitor. After the initial clinical evaluation, the patient was referred for renal angiography, which revealed critical stenosis of the proximal left common iliac artery, just above the renal graft artery anastomosis. The patient underwent successful angioplasty and stenting of the lesion, with complete normalization of blood pressure.

O autor estudou a eficácia terapêutica e a tolerabilidade do terconazol creme vaginal 0,8 por cento em dois grupos de pacientes portadoras de candíase vaginal: 21 grávidas e 19 nåo grávidas. A confirmaçäo diagnóstica, anterior ao tratamento, e a comprovaçäo da cura, pós-tratamento, foram realizadas através da cultura em meio de Nickerson. O medicamento foi utilizado na posologia de um aplicador vaginal durante cinco noites consecutivas. A avaliaçäo do quadro clínico, antes e depois do terconazol, mostrou rápido alívio dos sintomas, logo após as primeiras aplicaçöes. A cura micológica foi de 100 por cento nas pacientes grávidas e de 95 por cento nas pacientes näo grávidas. A avaliaçäo global do efeito terapêutico revelou resultados excelentes e bons em 90 por cento das pacientes grávidas. Conclusäo é de que o terconazol constitui alternativa eficaz e segura na terapêutica da candidíase vaginal

Secnidazol em dose única no tratamento da tricomoníase vaginal: comparaçäo entre a administraçäo matinal e a noturna / Single-dose of secnidazole in the treatment of vaginal trichomoniasis: a comparison between matinal and evening dosis

Este foi um estudo comparativo, simples-cego, com grupos paralelos, onde se avaliou a eficácia e a tolerabilidade do secnidazol, administrado em dose única de dois gramas (4 comprimidos de 500 mg) no tratamento da tricomoníase vaginal. Uma populaçäo de 111 pacientes foi incluída no estudo, dividida em dois grupos: um grupo de 68 pacientes recebeu o secnidazol no café da manhä e duas cápsulas de placebo no jantar, enquanto que o outro, com 43 pacientes, teve tratamento invertido. O mesmo esquema foi adotado para os parceiros sexuais. A eficácia do secnidazol foi considerada excelente, tendo havido cura da tricomoníase em 100% das pacientes no 7§ dia após o tratamento. A tolerabilidade foi melhor no grupo que recebeu secnidazol no período vespertino em relaçäo ao número e intensidade de reaçöes colaterais, quando comparado ao grupo matinal de tratamento
