Medication knowledge in patients with chronic kidney disease

O adequado conhecimento dos pacientes sobre os medicamentos que utilizam é considerado um fator fundamental para a adesão ao tratamento. O nível de conhecimento sobre a terapia farmacológica de pacientes com doença renal crônica (DRC) e os fatores associados a este conhecimento foram avaliados em um estudo transversal envolvendo 130 indivíduos em uso contínuo de algum medicamento pertencente aos grupos C, H02 ou L04 da classificação Anatomical Therapeutic Chemical e que não estivessem sendo submetidos a qualquer terapia de substituição renal. O nível de conhecimento foi mensurado através de um questionário e um escore de zero a dez pontos. Foram estabelecidos três níveis de conhecimento: baixo (menos de seis pontos), médio (seis a oito pontos) e bom (mais de oito pontos). O escore médio foi de 7,8 ± 1,7 pontos e 51,5% dos pacientes apresentaram nível de conhecimento baixo ou médio. Os fatores associados ao alto nível de conhecimento foram: declínio rápido do ritmo de filtração glomerular, controle da pressão arterial e crença do paciente em já ter sofrido reação adversa a algum medicamento prescrito. A maioria dos entrevistados possuía conhecimentos insuficientes para o uso seguro e eficaz dos medicamentos, o que sugere a necessidade de melhor orientação aos pacientes.The suitable patients' medication knowledge is a essential factor for the medication compliance. The level of medication knowledge in patients with chronic kidney disease (CKD) and the medication knowledge associated factors were assessed in a cross-sectional study performed with 130 subjects from a nephrology outpatient university clinic, continuously taking some self-administered drug from the C, H02 or L04 groups of the Anatomical Therapeutic Chemical classification system and who were not on a kidney replacement therapy. The level of medication knowledge was measured through a researcher-administered questionnaire and a score ranking from zero to ten points. Three levels of knowledge were defined: low (less than six points), moderate (six to eight points) and high (more than 8 points). The patients' medication knowledge average score was 7.8 ± 1.7 points and 51.5% of the patients showed low or moderate level of knowledge. The factors associated to the high level of medication knowledge were: fast decline of the glomerular filtration rate, control of the blood pressure and the patients' belief that they suffered adverse drug reaction to any of the prescribed medicines. Most patients had insufficient knowledge for a safe and effective use of prescribed medicines, so a better patient counseling is necessary

Granuloma Piogênico em Receptor de Transplante Renal

Objetivos: Este trabalho descreve um caso clínico de granuloma piogênico com apresentação e evolução atípicas, e traça uma breve revisão bibliográfica sobre a entidade nosológica. Introdução: O granuloma piogênico é uma lesão cutânea benigna comum, geralmente pequena, com algumas localizações mais comuns e predomínio no sexo feminino na idade adulta. Tem correlação com trauma e medicamentos. Sua fisiopatologia está em fase inicial de compreensão. Tem como alteração histopatológica típica um arranjo lobular dos capilares na base. O tratamento é cirúrgico, com baixa taxa de recidiva; há alternativas não-cirúrgicas. Relato do Caso: trata de um paciente de 25 anos, que 2 anos após realizar transplante renal de doador falecido desenvolve um granuloma piogênico gigante em antebraço direito após um trauma leve. Realiza sucessivas excisões cirúrgicas, apresenta recidivas, e evolui com resolução apenas após suspensão do tacrolimus e realização de radioterapia. As peculiaridades deste caso são: status de póstransplante renal, grande tamanho, recidivas após cirurgia e realização de radioterapia. Conclusões: Um paciente com granuloma piogênico, com evolução atípica, teve desfecho favorável após identificação e retirada de fator causal e terapia alternativa. Porém, este relato tem limitado potencial de generalização. Há poucas publicações de séries de casos envolvendo situações não-usuais, além do acometimento de mucosa oral, regiões paraungueais/subungueais e casos em gestantes. A radioterapia é uma intervenção pouco realizada, que pode ter valor em casos refratários. Mais estudos são necessários para atingir maior compreensão desta patologia e para descrever alternativas de tratamento

Association between stress and breast cancer in women: a meta-analysis

The objective of the current meta-analysis was to verify the association between stressful life events and primary breast cancer incidence in women. A total of 618 studies from 1982-2007 were found in the PubMed, LILACS, and Cochrane Library databases. Methodological quality was evaluated according to the Downs &amp; Black criteria. Eight studies were selected (six case-controls and two cohorts). The studies were grouped in three analyses, two of which based on the categories widowhood and divorce and the other based on self-rated intensity and frequency of stressful events. Relative risks were: widowhood 1.04 (95%CI: 0.75-1.44; p = 0.800); divorce 1.03 (95%: 0.72-1.48; p = 0.850); and intensity/frequency of stress 1.73 (95%CI: 0.98-3.05; p = 0.059). We conclude that stressful life events as a whole are not associated with risk of breast cancer in women. However, it is not possible to rule out high-intensity stress as a risk factor for breast cancer

Spectrum of acute kidney injury associated with cocaine use: report of three cases

Abstract Background The consequences of cocaine use are multisystemic, such as, for instance, renal failure, hepatotoxicity and pulmonary toxicity, with renal alterations being the focus of the present study. The use of substances that modify the base composition of cocaine (or adulterants) aiming to potentiate its effects also has an impact on these manifestations. The present study aims to report three cases with different diagnosis of acute kidney injury related to cocaine use. Case presentation Case 01 - A 30-year-old female patient, who regularly used cocaine, started to have lower-limb edema, which showed a progressive and ascending evolution, affecting the face a few days later, associated with an isolated febrile episode and oligoanuria. The presence of cytoplasmic antineutrophil cytoplasmic antibodies (C-ANCA) was verified: reactive 1:80, with renal biopsy compatible with rapidly progressive glomerulonephritis (RPGN). Case 02 - A 34-year-old female patient, with difficult-to-control hypertension and a frequent user of cocaine, showed generalized sudden edema together with diffuse and progressive pruritus associated with oliguria, fever, nausea, and vomiting. Schistocyte screening was positive, with negative direct Coombs test, and negative serologies for hepatitis B, C and HIV, as well as negative anti-double-stranded DNA, Anti-SSA and Anti-SSB. The renal biopsy was compatible with thrombotic microangiopathy, associated with moderate interstitial fibrosis and acute tubular necrosis Case 03 - A 25-year-old male patient who had been a cocaine user for 5 years had a sudden onset of generalized disabling myalgia (especially in the lower limbs) associated with recent frontotemporal headache, palpitation, dizziness, and a non-measured febrile episode; the patient had used cocaine at the night before symptom onset. CPK was 1731 U/L.The final probable diagnosis was AKI secondary to cocaine-induced rhabdomyolysis. Conclusions In conclusion basically, 05 etiologies of acute kidney injury should always be remembered: rhabdomyolysis, thrombotic microangiopathy, vasculitis, acute interstitial nephritis and renal infarction. Emphasis should be given to rhabdomyolysis due to its higher prevalence. Considering the increasing rates of cocaine use, especially with the use of adulterating substances, these pathologies will likely be increasingly prevalent

The impact of deceased donor maintenance on delayed kidney allograft function: A machine learning analysis.

BACKGROUND:This study evaluated the risk factors for delayed graft function (DGF) in a country where its incidence is high, detailing donor maintenance-related (DMR) variables and using machine learning (ML) methods beyond the traditional regression-based models. METHODS:A total of 443 brain dead deceased donor kidney transplants (KT) from two Brazilian centers were retrospectively analyzed and the following DMR were evaluated using predictive modeling: arterial blood gas pH, serum sodium, blood glucose, urine output, mean arterial pressure, vasopressors use, and reversed cardiac arrest. RESULTS:Most patients (95.7%) received kidneys from standard criteria donors. The incidence of DGF was 53%. In multivariable logistic regression analysis, DMR variables did not impact on DGF occurrence. In post-hoc analysis including only KT with cold ischemia time<21h (n = 220), urine output in 24h prior to recovery surgery (OR = 0.639, 95%CI 0.444-0.919) and serum sodium (OR = 1.030, 95%CI 1.052-1.379) were risk factors for DGF. Using elastic net regularized regression model and ML analysis (decision tree, neural network and support vector machine), urine output and other DMR variables emerged as DGF predictors: mean arterial pressure, ≥ 1 or high dose vasopressors and blood glucose. CONCLUSIONS:Some DMR variables were associated with DGF, suggesting a potential impact of variables reflecting poor clinical and hemodynamic status on the incidence of DGF

Prognostic factors for chronic kidney disease and end-stage renal disease in patients with lupus nephritis: A retrospective cohort study

Background: Lupus Nephritis (LN) occurs in approximately half of all patients with Systemic Lupus Erythematosus (SLE) and it is the most common cause of morbidity and mortality in patients with SLE. Factors associated with poor renal outcome vary among studies, and researches coming from Brazil are scarce. Objectives: To identify the prognostic factors associated to the development of Chronic Kidney Disease (CKD) and End Stage Renal Disease (ESRD) in LN patients followed in a tertiary hospital. Design and Settings: We conducted a retrospective cohort study set in a tertiary hospital in Fortaleza, Cear&aacute;, Brazil. Methods: We compiled a total of 214 LN patients diagnosed between 1983 and 2015. Data was collected from medical records and further analyzed using logistic regression. Results: LN prevalence was 53.9%. The cohort had a mean follow-up of 11.2 years (SD &plusmn; 7.2 years). At the end of follow-up, 93 of 197 patients (47.2%) had CKD, and 49 of 191 (25.6%) were on regular dialysis. The main factors associated for developing CKD after logistic regression analysis were the following predictors: hypertension (HR 2.80; 95% CI 1.30-6.01; p = 0.008), time between diagnosis of SLE and diagnosis of LN (HR 0.98; 95% CI 0.97-0.99; p = 0.009) and discontinuation of medications (HR 2.41; 95% CI 1.08-5.37; p = 0.03). Conclusion: Hypertension, discontinuation of medications, and time between diagnosis of SLE and diagnosis of LN are independent variables associated with the development of CKD and ESDR in our study.&nbsp

Prevalence of clinically validated primary causes of end-stage renal disease (ESRD) in a State Capital in Northeastern Brazil

<div><p>ABSTRACT Introduction: Knowledge of validated primary causes of end-stage renal disease (ESRD) is extremely relevant in the realm of public health. The literature lacks validated studies on the primary causes of ESRD. Objective: The aim of this study was to estimate the prevalence of the causes of ESRD in a State Capital in Northeastern Brazil. Methods: This cross-sectional study was based on the analysis of medical records of patients on hemodialysis at five specialized centers in Fortaleza, CE, Brazil. Deaths and patients referred to other centers outside Fortaleza were excluded from the study. The data of 830 patients were initially collected, but 818 remained enrolled after the exclusion criteria were applied, the equivalent to 48% of the patents on dialysis in the city. Results: 61.1% of the patients were males. Twenty-two percent of all enrolled individuals were aged 60-69 years. Patient mean age was 55.7 ± 16 years. The most common validated cause of ESRD was unknown (35.3%), followed by diabetes mellitus (26.4%), adult polycystic kidney disease (6.2%), graft failure (6.2%), obstructive uropathy (5.7%), and primary glomerulonephritis (5.3%). Before validation, primary hypertension was the most frequent cause of chronic kidney disease (22.9%), decreased to 3.8% after validation. Conclusion: The data contradicted national studies reporting primary hypertension as the main cause of chronic kidney disease (CKD). A high rate of unknown causes and categorization bias were observed mainly in relation to primary hypertension as a cause of CKD, which affects the overall prevalence of causes of ESRD in patients on dialysis.</p></div
