AKI is an important complication of anabolic steroid and vitamin supplement abuse. The exact pathophysiology of this type of AKI remains unclear. The main cause of renal dysfunction in these cases seems to be the vitamin D intoxication and drug-induced interstitial nephritis. It is mandatory to start early treatment for serious hypercalcemia, with vigorous venous hydration, diuretics and corticosteroids.

BackgroundThere is no information about HRQoL, depression and associated factors in adult with nephrotic syndrome-associated glomerulopathy.Methodology/Principal FindingsPatients with primary glomerulopathy where compared with age and sex-matched hemodialysis patients and healthy subjects. Laboratory data, medical history, comorbid conditions were collected to evaluate factors associated with HRQoL (SF-36) and Depression (Hamilton Depression Rating Scale - HAMD). Glomerulopathy patients had low HRQoL in all eight SF-36 domains and two composite scores (physical and mental) in comparison with healthy subjects. HAMD score also was elevated and there was high depression prevalence. Overall, these data were comparable between glomerulopathy and hemodialysis patients. Using multiple regression analysis, factors associated with low HRQoL physical composite score were: last 24 h-urine protein excretion (−0.183, 95%CI −0.223 to −0.710 for each gram of proteinuria, p = 0.01) and cyclosporine use (−15.315, 95%CI −25.913 to −2.717, p = 0.03). Low HRQoL mental composite score was associated with last 24 h-urine protein excretion (−0.157, 95%CI −0.278 to −0.310 for each gram of proteinuria, p = 0.03) and HMAD score was independently associated with age (0.155, 95%CI 0.318 to 0.988 for each year, p = 0.04), female sex (4.788, 95%CI 1.005 to 8.620, 0 = 0.03), disease duration (0.074, 95%CI 0.021 to 0.128 for each month, p = 0.01) and last 24 h-urine protein excretion (0.050, 95%CI 0.018 to 0.085 for each gram of proteinuria, p = 0.02).Conclusions/SignificanceNephrotic-syndrome associated glomerulopathy patients have low HRQoL and high prevalence of depression symptoms, comparable with those of hemodialysis patients. Last 24 h-protein excretion rate is independently associated with physical and mental HRQoL domains in addition to depression.

Introdução: Estudos comparam taxa de óbitos de Unidade de Terapia Intensiva (UTI) no Brasil que se encontra acima da internacional, não se sabendo se isso é devido ao sistema público brasileiro ou a falhas de registro. Objetivo: Traçar uma relação entre mortalidade prevista e características dos pacientes internados na UTI de hospital terciário de grande porte do município de Fortaleza, Ceará. Métodos: Trata-se de um estudo retrospectivo, analítico e transversal sobre pacientes internados na UTI do Hospital Geral de Fortaleza de janeiro a novembro de 2016. Resultados: No período da pesquisa, foram estudados 137 pacientes; desse total vieram a óbito 31 pacientes (24,48%). De acordo com a prioridade estabelecida pela Society Critical Care Medicine para Unidade de Terapia Intensiva, tivemos 53,3% na prioridade I, 10,0% na prioridade II, 30,0% na prioridade III, 3,3% na prioridade IVA e 3,3% na prioridade IVB, resultados estatisticamente significantes (p=0,012). Constatou-se neste trabalho que 80,6% dos óbitos haviam desenvolvido sepse durante o internamento na UTI (p<0,001). Aplicando-se os escores de mortalidade APACHE-II e SOFA, observa-se que o APACHE-II com escore médio de 22 pontos e com mortalidade prevista média de 55,7 (p<0,001), enquanto, o SOFA teve média no primeiro dia de 7 pontos (p<0,001), no quinto dia de 5 pontos (p=0,004) e no décimo dia de 5 pontos (p=0,004). Conclusão: Observou-se a importância da análise epidemiológica em relação aos óbitos ocorridos em Unidades de Terapia Intensiva, visando demonstrar a necessidade de se conhecer melhor a aplicabilidade dos escores SOFA e APACHE II e as medidas que devem ser adotadas.

BackgroundThe 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 presentationCase 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.ConclusionsIn 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.

CONTEXT AND OBJECTIVE: Glomerular disease registries are increasing all around the world. The aim of this study was to evaluate the clinical characteristics and treatment response among patients with glomerular diseases followed up in a tertiary hospital in Brazil. DESIGN AND SETTING: Analytical cross-sectional study; tertiary-level public hospital. METHODS:This study included patients with glomerular diseases followed up at a tertiary hospital in Fortaleza, northeastern Brazil. Clinical and laboratory data on each patient were registered. The response to specific treatment was evaluated after 3, 6 and 12 months. RESULTS:The study included 168 patients of mean age 37 ± 14 years. The main clinical presentations were nephrotic proteinuria (67.3%) and renal insufficiency (17.9%). The mean proteinuria value decreased after the treatment began. Regarding 24-hour proteinuria on admission, there was no significant difference between patients with a good response and those with no response (7,448 ± 5,056 versus 6,448 ± 4,251 mg/24 h, P = 0.29). The glomerular disease with the highest remission rate was MCD (92%). Absence of interstitial fibrosis presented a strong correlation with remission (remission in patients without fibrosis = 83.4% versus 16.3% in those with fibrosis, P = 0.001).CONCLUSIONS: The present study found that the most frequent glomerular disease was FSGS, followed by MCD, MN and LN. The presence of interstitial fibrosis was a predictor of poor therapeutic response. Com relação à proteinúria de 24 horas na admissão, não houve diferença significativa entre os pacientes com boa resposta ao tratamento e aqueles sem resposta (7.448 ± 5.056 versus 6.448 ± 4.251 mg/24 h, P = 0,29). A doença com maior índice de remissão foi a DLM (92%). A ausência de fibrose intersticial apresentou forte correlação com a remissão (remissão em pacientes sem fibrose = 83,4% versus 16,3% naqueles com fibrose, P = 0,001). CONCLUSÕES: O presente estudo encontrou como glomerulopatia mais frequente a GESF, seguida da DLM, NM e NL. A presença de fibrose intersticial foi um preditor de pobre resposta terapêutica. RESUMO

A doença inflamatória intestinal (DII) possui etiologia incerta, mas fatores ambientais, genéticos e imunológicos podem juntos justificar a patogênese, clínica e prognóstico desses pacientes. A manifestação clínica é diversa, sendo o acometimento renal um dos mais prevalentes, quando se exclui o trato gastrointestinal. Ademais, o papel genético na DII já foi mostrado em diversos trabalhos, principalmente em irmãos monozigóticos. A indução e manutenção do tratamento de casos leves/moderados de pacientes em remissão clínica apresenta boa eficácia com o uso de ácido 5-aminosalicílicos (mesalazina). Essa medicação, apesar de raro, também pode levar ao acometimento renal, com a nefrite intersticial sendo uma das principais etiologias. A seguir, descrevemos o caso de irmãos monozigóticos portadores de DII que desenvolveram nefrite intersticial em vigência de tratamento com mesalazina.
