RESUMO
This article presents a case of rapidly progressive glomerulonephritis following the Oxford-AstraZeneca COVID-19 vaccine in a female patient 58 years old. After 5 days, she presented fatigue, paleness, arthralgia on hands, knees, ankles, foamy urine, and elevated blood pressure. Exams showed serum creatinine of 2.2 mg/dL (baseline creatinine of 1.0 mg/dL). Urinalysis revealed hematuria, and her 24-h urinary protein excretion was 4.4 g. Additional exams showed hypercholesterolemia, severe anemia, and normal serum albumin. Testing of antineutrophil cytoplasmic antibodies anti-myeloperoxidase was positive at a titer of 1/80. Serum and urine protein electrophoresis and other exams showed no alterations. She was started on steroid pulse therapy after worsening kidney function, reaching serum creatinine of 3.3 mg/dL. A kidney biopsy revealed crescentic glomerulonephritis with glomerular sclerosis, fibrous crescents, interstitial fibrosis, and tubular atrophy. Induction therapy was given with intravenous cyclophosphamide 0.5 g/m2 for 6-monthly pulses, followed by maintenance therapy with oral azathioprine at 2 mg/kg and prednisone tapering. The patient did not develop any complications during the induction therapy, and is currently on maintenance therapy with a serum creatinine of 1.87 mg/dL.
RESUMO
The sundown syndrome is a complex neurobehavioral disorder in patients with dementia associated with high financial cost and significant caregiver burden. It is a multifactorial phenomenon with unclear pathophysiology, characterized by the presence of neuropsychiatric symptoms in the evening period. OBJECTIVE: To analyze the main neuropsychiatric symptoms, their correlation with one another, with comorbidities, and with time of day of greatest symptom intensity in patients with Alzheimer's disease dementia. METHODS: This is a cross-sectional, observational and explanatory study in which caregivers/relatives of elderly patients with dementia were interviewed using a structured tool called the Neuropsychiatric Inventory (NPI). RESULTS: The sample studied was composed of 38 patients, 60.5% female and 39.5% male, with mean age of 81±6 (67-94) years. A high frequency of neuropsychiatric symptoms in the evening period was observed, predominantly irritability (55.3%), nocturnal behavior (47.4%), and aggressiveness (42.1%). Only 36.8% of the family caregivers used non-pharmacological strategies. CONCLUSION: The frequency of neuropsychiatric symptoms was exacerbated in the evening among patients with Alzheimer's disease, especially for those behavioral symptoms that had a positive correlation with one another.
A síndrome do entardecer ou "pôr do sol" - "sundown syndrome" - é uma alteração neurocomportamental complexa em pacientes portadores de demência que geram custos financeiros excessivos e desgaste importante a seus cuidadores. Trata-se de um fenômeno multifatorial com fisiopatologia incerta, que caracteriza-se pela presença de sintomas neuropsiquiátricos no período vespertino. OBJETIVO: Analisar os principais sintomas neuropsiquiátricos, sua correlação entre si, com comorbidades e o horário do dia de maior intensidade destes em pacientes portadores de demência da doença de Alzheimer. MÉTODOS: Trata-se de um estudo analítico transversal, observacional e explanatório no qual foram entrevistados cuidadores/familiares de pacientes idosos portadores de demência utilizando uma ferramenta estruturada denominada Neuropsychiatric Inventory (NPI). RESULTADOS: A amostra estudada foi de 38 pacientes, 60,5% feminino e 39,5% masculino, com 81±6 (67-94) anos de idade. Foi observada uma alta frequência de sintomas neuropsiquiátricos no período vespertino, principalmente irritabilidade (55,3%), comportamento noturno (47,4%), agressividade (42,1%). Apenas 36,8% dos cuidadores familiares empregavam estratégias não farmacológicas. CONCLUSÃO: A frequência dos sintomas neuropsiquiátricos são exacerbados ao entardecer em pacientes com doença de Alzheimer; principalmente os sintomas comportamentais com correlação positiva entre si.
