- A single-centre, retrospective study of the incidence of invasive fungal infections during 85 years of autopsy service in Brazil(2021) DANTAS, Katia Cristina; MAUAD, Thais; ANDRE, Carmen D. Saldiva de; BIERRENBACH, Ana Luiza; SALDIVA, Paulo Hilario NascimentoAutopsy continues to play an essential role in monitoring opportunistic fungal infections. However, few studies have analysed the historical trends of fungal infections in autopsies. Here, we analyse available data on fungal infections obtained from autopsy reports during 85 years of autopsies performed by the largest autopsy service in Brazil. All invasive fungal infections presented in autopsy reports between 1930 and 2015 were included. Of the 158,404 autopsy reports analysed, 1096 involved invasive fungal infections. In general, paracoccidioidomycosis (24%) was the most frequent infection, followed by candidiasis (18%), pneumocystosis (11.7%), cryptococcosis (11%), aspergillosis (11%) and histoplasmosis (3.8%). Paracoccidioidomycosis decreased after the 1950s, whereas opportunistic fungal infections increased steadily after the 1980s during the peak of the AIDS pandemic. The lung was the most frequently affected organ (73%). Disseminated infection was present in 64.5% of cases. In 26% of the 513 cases for which clinical charts were available for review, the diagnosis of opportunistic fungal infections was performed only at autopsy. Our unique 85-year history of autopsies showed a transition from endemic to opportunistic fungal infections in SAo Paulo, Brazil, reflecting increased urbanization, the appearance of novel diseases, such as AIDS in the 1980s, and advances in medical care over time.

- Diffuse alveolar damage patterns reflect the immunological and molecular heterogeneity in fatal COVID-19(2022) ERJEFALT, Jonas S.; COSTA, Natalia de Souza Xavier; JONSSON, Jimmie; COZZOLINO, Olga; DANTAS, Katia Cristina; CLAUSSON, Carl-Magnus; SIDDHURAJ, Premkumar; LINDO, Caroline; ALYAMANI, Manar; LOMBARDI, Suzete Cleusa Ferreira Spina; MENDRONI JUNIOR, Alfredo; ANTONANGELO, Leila; FARIA, Caroline Silverio; DUARTE-NETO, Amaro Nunes; MONTEIRO, Renata Aparecida de Almeida; PINHO, Joao Renato Rebello; GOMES-GOUVEA, Michele Soares; PEREIRA, Roberta Verciano; MONTEIRO, Jhonatas Sirino; SETUBAL, Joao Carlos; OLIVEIRA, Ellen Pierre de; THEODORO FILHO, Jair; SANDEN, Caroline; ORENGO, Jamie M.; SLEEMAN, Matthew A.; SILVA, Luiz Fernando Ferraz da; SALDIVA, Paulo Hilario Nascimento; DOLHNIKOFF, Marisa; MAUAD, ThaisBackground Severe COVID-19 lung disease exhibits a high degree of spatial and temporal heterogeneity, with different histological features coexisting within a single individual. It is important to capture the disease complexity to support patient management and treatment strategies. We provide spatially decoded analyses on the immunopathology of diffuse alveolar damage (DAD) patterns and factors that modulate immune and structural changes in fatal COVID-19. Methods We spatially quantified the immune and structural cells in exudative, intermediate, and advanced DAD through multiplex immunohistochemistry in autopsy lung tissue of 18 COVID-19 patients. Cytokine profiling, viral, bacteria, and fungi detection, and transcriptome analyses were performed. Findings Spatial DAD progression was associated with expansion of immune cells, macrophages, CD8+ T cells, fibroblasts, and (lymph)angiogenesis. Viral load correlated positively with exudative DAD and negatively with dis-ease/hospital length. In all cases, enteric bacteria were isolated, and Candida parapsilosis in eight cases. Cytokines correlated mainly with macrophages and CD8+T cells. Pro-coagulation and acute repair were enriched pathways in exudative DAD whereas intermediate/advanced DAD had a molecular profile of elevated humoral and innate immune responses and extracellular matrix production. Interpretation Unraveling the spatial and molecular immunopathology of COVID-19 cases exposes the responses to SARS-CoV-2-induced exudative DAD and subsequent immune-modulatory and remodeling changes in proliferative/advanced DAD that occur side-by-side together with secondary infections in the lungs. These complex features have important implications for disease management and the development of novel treatments.
