ABSTRACT Introduction: Granulomatous interstitial nephritis is a rare condition, in which renal involvement is uncommon. Its etiology is variable, and may be medicinal, infectious or inflammatory origin. Case report: This is a 65-year-old male patient with renal lesions of unknown etiology, associated with hypercalcaemia. During the investigation, cardiac insufficiency with diastolic dysfunction and interstitial lung involvement on chest tomography were evidenced. Renal function (glomerular filtration rate) has partially improved with clinical measures. Renal biopsy was performed, which showed moderate interstitial lesion with tuberculoid granulomas without caseous necrosis. Conclusion: The objective of the article was to describe a case of NIG and to alert to the importance of its clinical investigation. In this case, renal biopsy, associated with systemic clinical manifestations, contributed to the diagnosis of sarcoidosis.

We report on a case of a patient with HIV infection, diagnosed 18 months prior to the development of an anti-glomerular basement membrane (anti-GBM) rapidly progressive glomerulonephritis; this is probably the first report of such an association. A 30-year-old white man presented with elevation of serum creatinine (1.3 - 13.5 mg/dL within one month). At admission, the urinalysis showed proteinuria of 7.2 g/L and 8,000,000 erythrocytes/mL. Renal biopsy corresponded to a crescentic diffuse proliferative glomerulonephritis mediated by anti-GBM, and serum testing for anti-GBM antibodies was positive; antinuclear antibodies (ANA) and anti-neutrophilic cytoplasmic antibodies (ANCA) were also positive. The patient underwent hemodyalisis and was treated with plasmapheresis, cyclophosphamide and prednisone. The association described here is not casual, as crescentic glomerulonephritis is not common in HIV-positive patients, anti-GBM glomerulonephritis is rare and anti-GBM antibodies are frequently observed in HIV-positive subjects when compared to the overall population. Based on the current case and on the elevated frequency of the positivity for such antibodies in this group of patients, it is advisable to be aware of the eventual association between these two conditions and to promote an active search for anti-GBM antibodies and early diagnosis of eventual urinary abnormalities in HIV-positive subjects, considering the severity of anti-GBM glomerulonephritis.

- Abstract
Introdução e objetivo: Frequentemente os pacientes críticos com COVID-19 evoluem para lesão renal aguda e necessidade de hemodiálise. O objetivo deste estudo foi comparar o perfil de atendimento aos pacientes críticos submetidos a terapia de substituição renal antes e durante a pandemia pela COVID-19. Métodos: Estudo observacional realizado em um hospital universitário da cidade de São Paulo, Brasil. Participaram do estudo pacientes críticos em hemodiálise de abril a junho de 2019 e abril a junho de 2020. Os dados foram coletados a partir de documentos de atendimento de hemodiálise e prontuário eletrônico. Foram utilizados os testes de Qui-quadrado, Mann-Whitney, Shapiro-Wilk, Teste Exato de Fisher, (significância de 5%). Resultados: Participaram 221 pacientes, sendo 50 em 2019 e 171 em 2020. Em 2019, 30,0% dos pacientes internaram por alterações renais agudas, 90,0% apresentaram creatinina de entrada aumentada, foram encaminhados para terapia intensiva após 4,62±6,38 dias e iniciaram hemodiálise após 17,26±24,53 dias. Em 2020, 66,7% internaram por COVID-19, 77,7% tiveram creatinina de entrada aumentada, foram encaminhados para terapia intensiva após 2,21±3,63 dias e iniciaram a hemodiálise após 10,24±11,99 dias. Foram realizadas 212 sessões de hemodiálise em 2019 e 873 em 2020. Houve mais óbitos em 2020 (p=0,01) e os pacientes com COVID-19 (p=0,014) e instabilidade hemodinâmica (p=0,016) foram os mais acometidos. Conclusão: Em 2020, foi observado aumento de 3,42 vezes no número de pacientes críticos em hemodiálise e aumento de 4,11 vezes no número de sessões quanto comparado ao ano de 2019.

Background: There are few reports of glomerulonephritis (GN) with crescents and a rapidly progressive course that lead to a diagnosis of a previously unsuspected B-cell dyscrasia. Case Presentation: We report a case of rapidly progressive GN: the patient showed no evidence of etiology at the time of biopsy and was diagnosed as IgA multiple myeloma (MM) during investigation based on a renal biopsy. He presented diffuse proliferative and exudative GN and marked plasma cell infiltration of the kidney. Conclusion: The present case raises the possibility that proliferative GN with crescents may be a rare mode of presentation of MM.

- Abstract
Introdução: A lesão renal aguda (LRA) é uma síndrome presente em vários contextos clínicos, e está associada a alta morbidade e mortalidade. A creatinina sérica é o biomarcador mais utilizado, mas apresenta limitações, uma vez que demonstra elevação apenas quando a lesão renal já está instituída. O processo inflamatório renal é um componente importante na fisiopatologia da LRA, não somente quando decorrente de sepse, mas também na lesão renal de origem não-infecciosa. A LRA séptica é uma disfunção orgânica, causada por resposta imune desregulada, após a exposição a um patógeno. A resposta imune inicial desencadeia uma resposta inflamatória secundária complexa, que leva à lesão renal. A rabdomiólise, por sua vez, é uma síndrome desencadeada por lesão extensa do tecido muscular, ocorrendo em diversas condições como no trauma, em intoxicações e como efeito adverso a medicamentos. Peptídeos antimicrobianos (AMPs) são um grupo de proteínas ancestrais, componentes do sistema imune inato, que além de atuarem na lise direta de patógenos, apresentam funções importantes na modulação da resposta imune, ainda não totalmente esclarecidas. Os AMPs mais estudados são as catelicidinas e as defensinas. Utilizando dois modelos experimentais distintos (sepse e rabdomiólise), induzimos LRA em camundongos knockout para o gene da catelicidina (CRAMP KO) e seus controles selvagens (C57BL/6), a fim de investigar potenciais diferenças na resposta imune entre esses diferentes modelos. Metodologia: Camundongos knockout para o gene da catelicidina e controles selvagens C57BL/6 foram submetidos a rabdomiólise por meio de injeção intramuscular de glicerol, após restrição hídrica. Um outro grupo foi submetido à sepse, pelo modelo de ligadura e punção cecal (CLP). Um terceiro grupo não foi submetido a nenhum modelo experimental (controles saudáveis). Foi realizada a dosagem de citocinas e de peptídeos antimicrobianos pelos métodos ELISA e Milliplex®, em material coletado desses animais. A lesão renal também foi avaliada por histologia, utilizando-se um escore de lesão tubular. Resultados: Os animais CRAMP KO submetidos à rabdomiólise apresentaram maior mortalidade do que os correspondentes selvagens, o que foi atribuído à maior inflamação tecidual renal, comprovada pela maior dosagem de IL-1, IL-6 e TNF- no tecido renal. Não houve diferença significativa nos níveis das mesmas citocinas no soro. O modelo de rabdomiólise induziu maior expressão de NGAL e -defensina 3 no tecido renal dos animais CRAMP KO. A maior inflamação no grupo rabdomiólise também foi confirmada por histologia. Em comparação à sepse, o modelo de rabdomiólise induziu maiores valores de creatinina e ureia, embora não tenha havido diferença estatística significativa. Discussão: Estudos prévios demonstraram que os camundongos CRAMP KO são mais resistentes à sepse. No modelo de rabdomiólise, os animais CRAMP KO apresentaram maior mortalidade, associada a maior inflamação renal local, sem repercussão sistêmica ou lesão de órgãos à distância. O modelo de sepse induziu maior expressão de -defensina 1 e 3 no tecido renal em ambos os grupos, mas não houve diferença estatisticamente significativa. Na sepse, a análise dos valores de NGAL e do escore de lesão tubular não mostrou diferença entre os grupos. Conclusão: Camundongos CRAMP KO são mais suscetíveis à lesão renal induzida pelo modelo de rabdomiólise e apresentam maior inflamação tecidual. Entretanto, quando submetidos a um modelo de sepse, são mais resistentes. As catelicidinas, portanto, podem induzir respostas inflamatórias distintas, até mesmo contraditórias, dependendo do contexto celular e patológico subjacentes Introduction: Acute kidney injury (AKI) is a syndrome related to various clinical situations, and is associated with high morbidity and mortality. Even though creatinine is the most frequently used biomarker, it has limitations, since it increases only when kidney injury is already established. Inflammation plays a major role in AKI pathophysiology, not only when it is associated with sepsis, but also in non-infectious diseases. Septic AKI is a frequent organ dysfunction in sepsis, a situation where deregulation of the immune response occurs in consequence of exposure to pathogens. The initial immune response leads to a complex secondary inflammatory response, which triggers renal injury. Rhabdomyolysis is a syndrome caused by extensive muscular damage, which occurs in various conditions, such as trauma, intoxication and adverse drug reactions. Antimicrobial peptides (AMPs) constitute a group of ancestral proteins, which integrate the innate immune system. Beyond their capacity to directly kill pathogens, they are also able to modulate the immune response, through mechanisms not yet fully explained. The most studied AMPs are the cathelicidins and the defensins. Using two experimental models (sepsis and rhabdomyolysis) we induced AKI in mice, to evaluate potential differences in the immune response. Methodology: Wild-type (WT) and cathelicidin-deficient mice (CRAMP KO) were subjected to rhabdomyolysis by intramuscular glycerol injection, after water deprivation. Another group was submitted to sepsis by the cecal ligation and puncture (CLP) model. A third group was not subjected to any experimental procedure (healthy controls). Several cytokines and antimicrobial peptides were measured by ELISA and Milliplex® methods, in samples collected from these animals. Histological evaluation of the kidney tissue was also performed, utilizing a tubular injury score. Results: CRAMP KO mice subjected to rhabdomyolysis had higher mortality than WT animals. This was attributed to a higher renal tissue inflammation, as inferred by the higher local levels of IL-1, IL-6 e TNF-. The same cytokines showed no statistically significant difference in plasma among the study groups. The rhabdomyolysis model induced higher NGAL and -defensin 3 levels in the kidneys of CRAMP KO mice. The histological analysis also showed higher inflammation. Compared to sepsis, the rhabdomyolysis model induced higher creatinine and urea levels, but there was no statistically significant difference. NGAL measures and the tubular injury score also showed no difference in septic animals. Discussion: Previous studies showed that CRAMP KO mice are more resistant to sepsis. In the rhabdomyolysis model, CRAMP KO mice had higher mortality associated to a higher local kidney inflammation, with no systemic repercussion or distant organ dysfunction. The sepsis model induced higher expression of -defensin 1 and 3 in the renal tissue of both groups, but there was no significant difference in the NGAL levels or in tubular injury scores. Conclusion: CRAMP KO mice are more susceptible to AKI induced by rhabdomyolysis and have more tissue inflammation. However, they are more resistant to the sepsis model. Cathelicidins can induce distinct inflammatory responses, even contradictory, depending on the cellular and pathological contexts
