Abstract
Gut microbial irregularities can lead to increased gut inflammation and gut membrane damage in people with long covid. Symptoms such as cough and breathlessness are apparent in Covid 19 patients with harmful gut bacterial overgrowth. In Covid patients, antibiotic and dexamethasone treatment also aggravates gut microbial imbalances. Lactobacillus supplementation has been shown to lessen upper respiratory tract infection, increase gut bacterial diversity, improve gut wall integrity, reduce gastrointestinal symptoms and gut inflammation, decrease oxidative stress and improve immunity. This study analysed the efficacy of probiotics and prebiotics combined supplements in reducing the severity and longevity of symptomatic Covid infection. 126 participants with Covid symptoms consumed two capsules a day for a month of a supplement containing 5 species of Lactobacillus and chicory inulin. 32% of participants were in the early phase of infection, and 68% were in the late phase. Both early and late phase participants showed significant improvements in cough, fatigue, and subjective wellbeing after 30 days of intervention. The gut symptoms of 82% of the participants improved after a month of intervention. Inulin and Lactobacillus strains need to be studied further robustly to determine whether they provide additional benefits. Healthcare practitioners can use the results of this study to consider symbiotic interventions for those with Covid symptoms.

Plain language summary
Milk and dairy products are good sources of protein, calcium and other nutrients. However, many people experience lactose intolerance due to their digestive tract's inability to digest lactose, resulting in symptoms such as flatulence, abdominal pain and diarrhoea. Oral administration of certain friendly live microorganisms or probiotics can help digest lactose more efficiently as they have greater β-galactosidase (β-gal) activity. β-galactosidase is an enzyme responsible for the digestion of lactose in the dairy products. A total of twelve studies were included in this meta-analysis. The results of this meta-analysis showed an improvement in the symptoms of lactose intolerance in adult patients, following probiotic administration. Probiotic administration was also found to enhance the digestion of lactose and calcium absorption in adult patients. Healthcare professionals can use the results of this study to understand the potential benefits of oral supplementation of probiotics for adult lactose intolerance patients. However, further studies are needed to understand the relationship between calcium absorption and lactose digestion after probiotic administration.
Abstract
This meta-analysis aimed to investigate the effect of probiotic administration on adults with lactose intolerance. Twelve studies were identified from databases such as PubMed, Cochrane Library, and Web of Knowledge based on the inclusion and exclusion criteria. The effect size was estimated using the standardized mean difference (SMD), and Cochrane's Q test was used to evaluate the statistical heterogeneity of the effect size. Moderator analysis, including meta-ANOVA and meta-regression, were performed to determine the cause of heterogeneity in the effect size using a mixed-effect model. Egger's linear regression test was conducted to evaluate publication bias. The results showed that probiotic administration alleviated the symptoms of lactose intolerance, including abdominal pain, diarrhea, and flatulence. Among them, the area under the curve (AUC) showed the greatest decrease following probiotic administration (SMD, -4.96; 95% confidence interval, -6.92 to -3.00). In the meta-ANOVA test, abdominal pain and total symptoms decreased with monostrain probiotic administration. This combination was also effective for flatulence. The dosage of probiotics or lactose was significantly associated with a reduction in the total symptom score, and the linear regression models between the dosage and SMD were found to be Y = 2.3342 × dosage - 25.0400 (R2 = 79.68%) and Y = 0.2345 × dosage - 7.6618 (R2 = 34.03%), respectively. Publication bias was detected for most items. However, even after effect size correction, the probiotic administration effect for all items remained valid. The administration of probiotics was effective at improving adult lactose intolerance, and it is expected that the results of this study could help improve the nutritional status of adults by increasing their consumption of milk and dairy products in the future.

Plain language summary
Psoriasis is an immune-mediated chronic inflammatory skin disorder characterised by plaques and lesions on the skin. While the etiopathogenesis of psoriasis is not completely understood, various mechanisms have been implicated, including changes in the composition of intestinal microbes, oxidative stress and changes in the levels of certain trace elements. Previous research has shown that fluctuations in trace minerals such as zinc and copper may contribute to the progression and progression of psoriasis. It is known that synbiotics, which are combinations of probiotics and prebiotics, have immune-modulating properties, and they may also enhance the absorption of trace minerals from food when consumed. This double-blind, randomised, placebo-controlled trial was conducted to randomly assign sixty-four patients with mild-to-moderate psoriasis to consume Lactocare, a symbiotic containing seven strains of probiotic bacteria and prebiotic fructooligosaccharide twice daily or a placebo for 12 weeks. Serum trace mineral levels were measured after 12 weeks of treatment, including Fe, K, Ca, Mg, P, Zn, Na, and Cu. A significant improvement in serum levels of zinc and calcium was observed in the symbiotic group after 12 weeks of treatment. Additionally, the symbiotic treatment significantly increased the levels of trace minerals such as Fe, Ca, Mg, P, Zn, and Na within the group compared to the baseline. Fe and Cu levels in the treatment group were affected by sex, with male participants showing significant differences. To evaluate the other benefits of symbiotic preparations in patients with psoriasis, further large-scale studies are required. Healthcare professionals can utilise the research to understand the immune-modulating and anti-inflammatory properties of symbiotic formulations such as Lactocare, as well as to understand how the consumption of Lactocare improves the absorption of trace minerals.
Abstract
BACKGROUND Despite the exact etiopathogenesis of psoriasis remains unknown, the increasing or decreasing of some trace elements and oxidative stress status are considered to play a role. In this study, the effect of Lactocare® synbiotic on the serum levels of trace elements including Zn, Cu, Mg, Na, Fe, P, Ca, and K in the patients with mild to moderate psoriasis was investigated. METHODS Sixty-four patients with mild to moderate psoriasis were included. Patients were randomly divided into treatment (n═32) and control (n═32) groups. The treatment group received Lactocare® and the control group received a placebo (two times daily for 12 weeks). Eight patients from the intervention group and 18 patients from the control group discontinued the study because of the recent COVID-19 condition. For routine trace element analysis, the blood samples were collected from all patients at the baseline as well as week 12 post-treatment. The serum was then isolated and the serum levels of trace elements including Fe, K, Ca, Mg, P, Zn, Na, and Cu were measured using an automatic electrolyte analyzer. For confirmation of the effect of Lactocare® on the alteration of serum levels of trace elements, intra-group analysis was performed at two interval times: baseline and week 12 post-treatment. RESULTS The serum levels of K, P, and Ca in the placebo group were significantly higher than that of the treatment group at baseline. Serum levels of Zn and Ca were significantly higher in the treatment group compared to the placebo group at week 12 post-treatment. Moreover, a significantly lower serum level of K, P, and Ca in the treatment group at the baseline compared to the placebo group was compensated on week 12 post-treatment. Intra-group analysis in the treatment group showed that the serum levels of Fe, Ca, Mg, P, Zn, and Na was significantly increased at week 12 post-treatment compared to baseline levels. Whereas, intra-group analysis in the control group showed only Ca has a significant difference between baseline and week 12 post-treatment. CONCLUSION The serum levels of Fe, Zn, P, Mg, Ca, and Na are increased significantly 12 weeks after oral administration of Lactocare® in psoriatic patients. The serum level of Fe and Cu is affected by sex at pre- and post-treatment. This study supports the concept that Lactocare® exerts beneficial effects in the gastrointestinal tract to improve mineral absorption in psoriatic patients.
