RESUMO

Engineered probiotics (EPs) can be used to treat/manage chronic and congenital diseases. However, to the best of our knowledge, no systematic review has evaluated the effects of EPs on congenital metabolic disorders in murine models and human subjects. Thus, the present study systematically reviewed interventional studies that assessed the effects of EPs on congenital metabolic disorders. PubMed, Web of Science, and Scopus databases were searched up to February 2023 to retrieve related publications. Seventy-six articles were obtained in the primary step. After screening the titles/abstracts based on the inclusion and exclusion criteria, 11 papers were included. Finally, only seven articles were included after performing full-text evaluation. The included articles evaluated the effects of EPs on managing phenylketonuria (PKU, n=4) and hyperammonemia (n=3). Moreover, these studies examined mice and/or rats (n=6), monkeys (n=1), and humans (n=2). Studies on EPs and hyperammonemia revealed that some wild strains such as Lactobacillus plantarum have an innate ammonia-hyper-consuming potential; thus, there was no need to manipulate them. However, manipulation is needed to obtain a phenylalanine-metabolizing strain. In conclusion, EPs can be used to manage or treat congenital metabolic diseases including PKU.

RESUMO

Rheumatoid arthritis (RA) and osteoarthritis (OA) both are chronic diseases affecting joints. Immune response against collagen in both diseases may have a role in the initiation and progression of the disease. There is a hypothesis that suppression of immune response vs collagen could be a therapeutic approach in RA and OA. Exposure of gut immune system to collagen is a way to suppress immune response against collagen in the joints. So, the current systematic review is aimed to evaluate the effects of collagen supplementation in OA and RA patients. In the current systematic review, online electronic databases including PubMed/MEDLINE, Web of Sciences and Scopus were searched and finally 19 articles were included. The enrolled articles evaluated the effects of collagen supplementation on treatment of OA (n = 9) and RA (n = 10). Intact (n = 4) and hydrolyzed (n = 5) collagen were used to treat OA. All of the studies on RA used intact and type II collagen in their intervention. The last trials on collagen supplementation in RA and OA patients were performed in 2011 and 2016, respectively. High adverse effects of collagen supplementation and its low efficiency compared to routine treatments were reported by several included studies. Also, risk of bias assessment showed that most of the studies had poor quality. Therefore, it is not possible to definitely decide on the beneficial or detrimental effects of collagen supplementation on OA and RA patients. Further studies are needed to reach a final decision.

RESUMO

Purpose: A body shape index (ABSI) and visceral; adiposity index (VAI) can reflect some cardio-metabolic risk factors in the population. To the best of our knowledge, there are no previous studies conducted on the assessment of the association between neurotrophic factors, Ghrelin and Obestatin with ABSI and VAI. We aimed to investigate this association among apparently healthy women. Methods: Ninety apparently healthy women were recruited in the present study. All participants were in need of dietary intervention for weight loss and participated in the study before receiving any intervention. Dietary, anthropometric, physical activity, stress level and biochemical assessments, as well as blood pressure measurements were done for all participants. Results: Women in the highest tertile of ABSI had significantly lower SBP compared to the lowest ABSI tertile. Women who were in the highest tertile of VAI had significantly lower serum Obestatin levels compared to the first and second tertiles in both crude and adjusted comparisons. Serum NGF, Obestatin and Ghrelin levels were significantly lower in the highest tertile of VAI compared to the lowest tertile in both crude and adjusted comparisons. HOMA-IR, serum insulin, LDL-C, TG and TC were significantly higher in the highest tertile of VAI compared to the lowest tertile. QUICKI in the highest tertiles were significantly lower than the first tertile in adjusted model. Conclusion: This evidence can be useful for researchers in applying appropriate anthropometric indices regarding different populations with multifactorial metabolic complications. The current findings need approving by prospective population study and also clinical trial researches.
