RESUMO

It is known that the inflammation process leading to oxidative stress and thyroid hormone metabolism dysfunction is highly altered in metabolic dysfunction associated with steatotic liver disease (MASLD). This study aims to address the effect of ornithine aspartate (LOLA) and vitamin E (VitE) in improving these processes. Adult Sprague-Dawley rats were assigned to five groups and treated for 28 weeks: controls (n = 10) received a standard diet (for 28 weeks) plus gavage with distilled water (DW) from weeks 16 to 28. MASLD groups received a high-fat and choline-deficient diet for 28 weeks (MASLD group) and daily gavage with 200 mg/kg/day of LOLA, or twice a week with 150 mg of VitE from weeks 16-28. LOLA diminished collagen deposition (p = 0.006). The same treatment diminished carbonyl, TBARS, and sulfhydryl levels and GPx activity (p < 0.001). Type 3 deiodinase increased in the MASLD group, downregulating T3-controlled genes, which was corrected in the presence of LOLA. LOLA also promoted a near-normalization of complex II, SDH, and GDH activities (p < 0.001) and improved reticulum stress, with a reduction in GRP78 and HSPA9/GRP75 protein levels (p < 0.05). The enhanced energy production and metabolism of thyroid hormones, probably because of GSH replenishment provided by the L-glutamate portion of LOLA, opens a new therapeutic approach for MASLD.

RESUMO

Morphometry of striated muscle fibres is critical for monitoring muscle health and function. Here, we evaluated functional parameters of skeletal and cardiac striated muscle in two experimental models using the Morphometric Analysis of Muscle Fibre tool (MusMA). The collagen-induced arthritis model was used to evaluate the function of skeletal striated muscle and the non-alcoholic fatty liver disease model was used for cardiac striated muscle analysis. After euthanasia, we used haeamatoxylin and eosin stained sections of skeletal and cardiac muscle to perform muscle fibre segmentation and morphometric analysis. Morphometric analysis classified muscle fibres into six subpopulations: normal, regular hypertrophic, irregular hypertrophic, irregular, irregular atrophic and regular atrophic. The percentage of atrophic fibres was associated with lower walking speed (p = 0.009) and lower body weight (p = 0.026), respectively. Fibres categorized as normal were associated with maximum grip strength (p < 0.001) and higher march speed (p < 0.001). In the evaluation of cardiac striated muscle fibres, the percentage of normal cardiomyocytes negatively correlated with cardiovascular risk markers such as the presence of abdominal adipose tissue (p = .003), miR-33a expression (p = .001) and the expression of miR-126 (p = .042) Furthermore, the percentage of atrophic cardiomyocytes correlated significantly with the Castelli risk index II (p = .014). MusMA is a simple and objective tool that allows the screening of striated muscle fibre morphometry, which can complement the diagnosis of muscle diseases while providing functional and prognostic information in basic and clinical research.

RESUMO

BACKGROUND: Metabolic-dysfunction associated steatotic liver disease (MASLD) is a hepatic manifestation of metabolic syndrome. Studies suggest ornithine aspartate (LOLA) as drug therapy. AIM: To analyze the influence of LOLA intake on gut microbiota using a nutritional model of MASLD. METHODS: Adult male Sprague Dawley rats were randomized into three groups: Control (10 rats fed with a standard diet), MASLD (10 rats fed with a high-fat and choline-deficient diet), and LOLA (10 rats receiving 200 mg/kg/d LOLA, after the 16th week receiving high-fat and choline-deficient diet). After 28 wk of the experiment, animals were euthanized, and feces present in the intestine were collected. Following fecal DNA extraction, the V4 region of the 16S rRNA gene was amplified followed by sequencing in an Ion S5™ system. RESULTS: Alpha and beta diversity metrics were comparable between MASLD and LOLA. 3 OTUs were differentially abundant between MASLD and LOLA, which belong to the species Helicobacter rodentium, Parabacteroides goldsteinii, and Parabacteroides distasonis. The functional prediction provided two different metabolic profiles between MASLD and LOLA. The 9 pathways differentially abundant in MASLD are related to a change in energy source, adenosine/purine nucleotides degradation as well as guanosine and adenosine deoxyribonucleotides biosynthesis. The 14 pathways differentially abundant in LOLA are associated with four major metabolic functions primarily influenced by L-aspartate, including tricarboxylic acid cycle pathways, purine/guanosine nucleotides biosynthesis, pyrimidine ribonucleotides biosynthesis and salvage as well as lipid IVA biosynthesis. CONCLUSION: Although LOLA had no influence on alpha and beta diversity in this nutritional model of MASLD, it was associated with changes in specific gut microbes and their related metabolic pathways.

RESUMO

Background and aim: Considering the increasing prevalence of non-alcoholic steatohepatitis (NASH) and treatment gaps, this study aimed to evaluate the effect of probiotic supplementation on liver function markers, nutritional status, and clinical parameters. Methods: This double-blind, randomized clinical trial (ClinicalTrials.gov ID: NCT0346782) included adult outpatients with biopsy-proven NASH. The intervention consisted of 24 weeks of supplementation with the probiotic mix Lactobacillus acidophilus (1 × 109 CFU) + Lactobacillus rhamnosus (1 × 109 CFU) + Lactobacillus paracasei (1 × 109 CFU) + Bifidobacterium lactis (1 × 109 CFU), or placebo, twice a day. The following parameters were evaluated: demographic and clinical data, transient elastography (FibroScan), liver enzymes, NAFLD fibrosis score, fatty liver index, laboratory assessment, serum concentration of toll-like receptor-4 (sTLR-4) and cytokeratin 18 (CK-18), anthropometric data, dietary intake, and physical activity. Regarding data analysis, the comparison between the groups was based on the delta of the difference of each variable analyzed (value at the end of treatment minus the baseline value) using the t-test for independent samples or the Mann-Whitney U-test. Results: Forty-four patients with NASH completed the trial (51.4 ± 11.6 years). At baseline, 87% of participants had a mild liver fibrosis degree on biopsy, normal values of liver enzymes, transient elastography values consistent with grade 1 fibrosis in both groups, increased waist circumference (WC), a BMI of 30.97 kg/m2, and 76% presented with metabolic syndrome (MetS). After the intervention, no differences were observed between the probiotic and placebo groups in terms of MetS, WC, BMI scores, or liver enzyme levels (p > 0.05 for all). The elastography values remained consistent with grade 1 fibrosis in both groups. Although CK-18 was reduced in both groups, a larger effect size was noted in the probiotic group (D = 1.336). sTLR-4 was also reduced in both groups, with no difference between groups (p = 0.885). Conclusion: Intervention with probiotics in the early stages of NASH demonstrated no significant change in hepatic and clinical parameters. Clinical trial registration: ClinicalTrials.gov, identifier NCT0346782.

RESUMO

BACKGROUND: Alcoholic liver disease (ALD) and metabolic-dysfunction associated steatotic liver disease (MASLD) are common, and gut microbiota (GM) is involved with both. Here we compared GM composition in animal models of MASLD and ALD to assess whether there are specific patterns for each disease. METHODS: MASLD model- adult male Sprague Dawley rats, randomized into two groups: MASLD-control (n=10) fed a standard diet; MASLD-group (n=10) fed a high-fat-choline-deficient diet for 16 weeks. ALD model- adult male Wistar rats randomized: ALD-control (n=8) fed a standard diet and water+0.05% saccharin, ALD groups fed with sunflower seed and 10% ethanol+0.05% saccharin for 4 or 8 weeks (ALC4, n=8; ALC8, n=8). ALC4/8 on the last day received alcoholic binge (5g/kg of ethanol). Afterwards, animals were euthanized, and feces were collected for GM analysis. RESULTS: Both experimental models induced typical histopathological features of the diseases. Alpha diversity was lower in MASLD compared with ALD (p<0.001), and structural pattern was different between them (P<0.001). Bacteroidetes (55.7%), Firmicutes (40.6%), and Proteobacteria (1.4%) were the most prevalent phyla in all samples, although differentially abundant among groups. ALC8 had a greater abundance of the phyla Cyanobacteria (5.3%) and Verrucomicrobiota (3.2%) in relation to the others. Differential abundance analysis identified Lactobacillaceae_unclassified, Lachnospiraceae_NK4A136_group, and Turicibacter associated with ALC4 and the Clostridia_UCG_014_ge and Gastranaerophilales_ge genera to ALC8. CONCLUSION: In this study, we demonstrated that the structural pattern of the GM differs significantly between MASLD and ALD models. Studies are needed to characterize the microbiota and metabolome in both clinical conditions to find new therapeutic strategies. BACKGROUND: •Changes in the composition of the intestinal microbiota are related to the development of alcoholic liver disease and metabolic-dysfunction associated steatotic liver disease. BACKGROUND: •The diversity of the intestinal microbiota was lower in animals with MASLD compared to ALD. BACKGROUND: •The structural pattern of the intestinal microbiota was significantly different among the experimental groups. BACKGROUND: •Studies are needed to characterize the composition of the intestinal microbiota and metabolome to find new therapeutic strategies.

RESUMO

Background/Aims: Extracellular vesicles (EVs) are promising as a biomarker of metabolic dysfunction associated steatotic liver disease (MASLD). The objective is to study EVs and their involvement in MASLD concerning the disease's pathogenesis and progression characteristics. Methods: Male adult Sprague Dawley rats were randomly assigned into two experimental models of MASLD: MASLD-16 and MASLD-28, animals received a choline-deficient high-fat diet (CHFD) and Control-16 and Control-28, animals received a standard diet (SD) for 16 and 28 weeks, respectively. Biological samples from these animal models were used, as well as previously registered variables. EVs from hepatic tissue were characterized using confocal microscopy. EVs were isolated through differential ultracentrifugation from serum and characterized using NanoSight. The data from the EVs were correlated with biochemical, molecular, and histopathological parameters. Results: Liver EVs were identified through the flotillin-1 protein. EVs were isolated from the serum of all groups. There was a decrease of EVs concentration in MASLD-28 in comparison with Control-28 (P < 0.001) and a significant increase in EVs concentration in Control-28 compared with Control-16 (P < 0.001). There was a strong correlation between serum EVs concentration with hepatic gene expression of interleukin (Il)6 (r2 = 0.685, P < 0.05), Il1b (r2 = 0.697, P < 0.05) and tumor necrosis factor-alpha (Tnfa; r2 = 0.636, P < 0.05) in MASLD-16. Moreover, there was a strong correlation between serum EVs size and Il10 in MASLD-28 (r2 = 0.762, P < 0.05). Conclusion: The concentration and size of EVs correlated with inflammatory markers, suggesting their involvement in the systemic circulation, cellular communication, and development and progression of MASLD, demonstrating that EVs have the potential to serve as noninvasive biomarkers for MASLD diagnosis and prognosis.

RESUMO

BACKGROUND: Prevalence of hepatocellular carcinoma (HCC) is increasing, especially in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). AIM: To investigate rifaximin (RIF) effects on epigenetic/autophagy markers in animals. METHODS: Adult Sprague-Dawley rats were randomly assigned (n = 8, each) and treated from 5-16 wk: Control [standard diet, water plus gavage with vehicle (Veh)], HCC [high-fat choline deficient diet (HFCD), diethylnitrosamine (DEN) in drinking water and Veh gavage], and RIF [HFCD, DEN and RIF (50 mg/kg/d) gavage]. Gene expression of epigenetic/autophagy markers and circulating miRNAs were obtained. RESULTS: All HCC and RIF animals developed metabolic-dysfunction associated steatohepatitis fibrosis, and cirrhosis, but three RIF-group did not develop HCC. Comparing animals who developed HCC with those who did not, miR-122, miR-34a, tubulin alpha-1c (Tuba-1c), metalloproteinases-2 (Mmp2), and metalloproteinases-9 (Mmp9) were significantly higher in the HCC-group. The opposite occurred with Becn1, coactivator associated arginine methyltransferase-1 (Carm1), enhancer of zeste homolog-2 (Ezh2), autophagy-related factor LC3A/B (Map1 Lc3b), and p62/sequestosome-1 (p62/SQSTM1)-protein. Comparing with controls, Map1 Lc3b, Becn1 and Ezh2 were lower in HCC and RIF-groups (P < 0.05). Carm1 was lower in HCC compared to RIF (P < 0.05). Hepatic expression of Mmp9 was higher in HCC in relation to the control; the opposite was observed for p62/Sqstm1 (P < 0.05). Expression of p62/SQSTM1 protein was lower in the RIF-group compared to the control (P = 0.024). There was no difference among groups for Tuba-1c, Aldolase-B, alpha-fetoprotein, and Mmp2 (P > 0.05). miR-122 was higher in HCC, and miR-34a in RIF compared to controls (P < 0.05). miR-26b was lower in HCC compared to RIF, and the inverse was observed for miR-224 (P < 0.05). There was no difference among groups regarding miR-33a, miR-143, miR-155, miR-375 and miR-21 (P > 0.05). CONCLUSION: RIF might have a possible beneficial effect on preventing/delaying liver carcinogenesis through epigenetic modulation in a rat model of MASLD-HCC.

RESUMO

BACKGROUND & AIM: Patatin-like phospholipase domain-containing 3 gene (PNPLA3) polymorphism has been implicated in susceptibility to non-alcoholic fatty liver disease (NAFLD), with evidence for potential interaction with nutrition. However, the combination of meat consumption with genetic polymorphism has not been tested. Therefore, this study aims to test the association between the joint presence of PNPLA3 rs738409 G-allele with high meat consumption and NAFLD in populations with diverse meat consumption. METHODS: A cross-sectional study among Israeli screening and Brazilian primary healthcare populations. Food consumption was assessed by a food-frequency questionnaire. PNPLA3 polymorphism was defined as homozygous (GG) or heterozygous (GC). Inconclusive/probable NAFLD was defined as a fatty liver index (FLI) ≥ 30 and probable NAFLD as FLI ≥ 60. RESULTS: The sample included 511 subjects from the screening and primary healthcare populations (n = 213 and n = 298, respectively). Genetic polymorphism (homozygous GG or heterozygous GC) combined with high consumption of total meat, red and/or processed meat, unprocessed red meat, and processed meat was associated with the highest odds for inconclusive/probable NAFLD (OR = 2.75, 95%CI 1.27-5.97, p = 0.011; OR = 3.24, 1.43-7.34, p = 0.005; OR = 2.92, 1.32-6.47, p = 0.008; OR = 3.16, 1.46-6.83, p = 0.003, respectively), adjusting for age, gender, BMI, alcohol consumption, carbohydrate, and saturated fat intake. In addition, genetic polymorphism combined with high processed meat consumption was associated with the highest odds for probable NAFLD (OR = 2.40, 95%CI 1.04-5.56, p = 0.040). CONCLUSIONS: High red meat intake may confer a greater risk for NAFLD among PNPLA3 polymorphism carriers. Prospective studies are needed to confirm these findings and consider minimizing red and processed meat consumption among PNPLA3 polymorphism carriers.

RESUMO Contexto: A doença hepática alcoólica (DHA) e a doença hepática esteatótica associada à disfunção metabólica (MASLD) são comuns, e a microbiota intestinal (MI) está envolvida em ambas. Aqui, comparamos a composição da MI em modelos animais de MASLD e DHA para avaliar se existem padrões específicos para cada doença. Métodos: Modelo de MASLD - ratos machos adultos da linhagem Sprague Dawley, randomizados em dois grupos: MASLD-controle (n=10) alimentados com uma dieta padrão; grupo MASLD (n=10) alimentados com uma dieta rica em gordura e deficiente em colina por 16 semanas. Modelo de DHA - ratos machos adultos da linhagem Wistar randomizados: DHA-controle (n=8) alimentados com uma dieta padrão e água+0,05% de sacarina; grupos DHA alimentados com semente de girassol e 10% de etanol+0,05% de sacarina por 4 ou 8 semanas (DHA4, n=8; DHA8, n=8). DHA 4/8 no último dia receberam binge alcoólico (5 g/kg de etanol). Posteriormente, os animais foram sacrificados, e as fezes foram coletadas para análise da MI. Resultados: Ambos os modelos experimentais induziram características histopatológicas típicas das doenças. A diversidade alfa foi menor na MASLD em comparação com a DHA (P<0,001), e o padrão estrutural foi diferente entre elas (P<0,001). Bacteroidetes (55,7%), Firmicutes (40,6%) e Proteobactérias (1,4%) foram os filos mais prevalentes em todas as amostras, embora com abundâncias diferenciadas entre os grupos. DHA8 teve uma maior abundância dos filos Cyanobacteria (5,3%) e Verrucomicrobiota (3,2%) em relação aos outros. A análise de abundância diferencial identificou Lactobacillaceae_unclassified, Lachnospiraceae_NK4A136 e Turicibacter associados ao grupo DHA4, e os gêneros Clostridia_UCG_014_ge e Gastranaerophilales_ge associados ao DHA8. Conclusão: Neste estudo, demonstramos que o padrão estrutural da MI difere significativamente entre os modelos de MASLD e DHA. Estudos são necessários para caracterizar a microbiota e os metabólitos ativos em ambas as condições clínicas, a fim de encontrar novas estratégias terapêuticas.

RESUMO

A leishmaniose visceral, conhecida também como calazar, trata-se da forma mais grave das leishmanioses por ser uma enfermidade sistêmica e com um grande espectro clínico e um caráter irregular. Desse modo, objetivou-se avaliar a situação epidemiológica da leishmaniose visceral no Estado de Goiás, bem como o caráter dessa doença e o perfil mais atingido. Para isso, foi realizada uma pesquisa retrospectiva compreendendo o período de 2012 a 2021, com os casos notificados de leishmaniose visceral no Estado de Goiás. A busca pelos dados ocorreu por meio dos SINAN/DATASUS do Ministério da Saúde. Os dados encontrados foram tabulados e analisados por meio do programa Excel da Microsoft®. No período avaliado, foram notificados 388 casos de LV em Goiás, distribuídos em 47 municípios goianos. 66,23% das ocorrências pertenciam ao sexo masculino; 25,51% eram adultos com idade entre 20- 39 anos; 74,48% eram moradores da zona urbana; além disso, 9,27% do total de casos notificados em Goiás evoluíram para óbito. Há ainda uma a taxa de coinfecção LV/HIV de 12,11% do total de casos notificados. Constatou-se, portanto, que algumas localidades possuem registros consequentes de LV, levando a existência de áreas endêmicas no estado. Existe um perfil de acometimento em Goiás, no período de análise, direcionado para o sexo masculino, de cor parda, jovens adultos, com baixa escolaridade, vivendo nas cidades e grandes centros urbanos. Destaca-se o elevado quantitativo de dados identificados como ignorado/branco, que podem interferir significativmente em análises epidemiológicas.


Visceral leishmaniasis, also known as kala-azar, is the most serious form of leishmaniasis because it is a systemic disease with a wide clinical spectrum and an irregular character. Thus, the objective was to evaluate the epidemiological situation of visceral leishmaniasis in the State of Goiás, as well as the character of this disease and the most affected profile. For this, a retrospective survey was carried out covering the period from 2012 to 2021, with reported cases of visceral leishmaniasis in the State of Goiás. The search for data took place through the SINAN/DATASUS of the Ministry of Health. The data found were tabulated and analyzed using the Microsoft® Excel program. In the period evaluated, 388 cases of VL were reported in Goiás, distributed in 47 munic- ipalities in Goiás. 66.23% of the occurrences were male; 25.51% were adults aged be- tween 20-39 years; 74.48% were residents of the urban area; in addition, 9.27% of the total cases reported in Goiás evolved to death. There is also a LV/HIV co-infection rate of 12.11% of the total reported cases. It was found, therefore, that some localities have consequent records of VL, leading to the existence of endemic areas in the state. There is a profile of involvement directed towards males, of mixed race, young adults, with low education, living in cities and large urban centers. The high quantity of data identified as ignored/white stands out, which can significantly interfere in epidemiological analyses. KEYWORDS: Epidemiology; Leishmania; Notification.

Existe también una tasa de coinfección LV/VIH de 12,11% del total de casos notificados. Se constató, por lo tanto, que algunas localidades tienen registros consecuentes de LV, llevando a la existencia de áreas endémicas en el estado. Existe un perfil de envolvimiento dirigido a hombres, mestizos, adultos jóvenes, con baja escolaridad, residentes en ciudades y grandes centros urbanos. Se destaca la elevada cantidad de datos identificados como ignorados/blancos, lo que puede interferir significativamente en los análisis epidemiológicos.
