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.

Plain language summary
Vitamins and minerals are essential for a healthy immune system. The prevalence of vitamin and mineral deficiencies increases with age, and this may contribute to age-related decline of the immune system. The aim of this study was to investigate whether a daily multivitamin and mineral (MVM) supplement could improve the immune function of older people. 42 healthy adults aged between 55 and 75 took part in this single-centre, two-armed, parallel, randomised, double-blinded study. Half of the group was given a MVM supplement called Redoxon Vita Immune (VI) containing the vitamins A, D, E, C, B6, B12 and folate plus iron, copper, zinc and selenium daily for 12 weeks, whilst the other half was given placebo tablets for 12 weeks. Participants were instructed to avoid certain foods high in vitamins and minerals such as oily fish, red meat, liver, and citrus fruits during the study period. Blood and saliva samples were taken from all participants at the beginning and end of the study period, to measure vitamin and mineral status and markers of immune function. Participants also kept a diary to record any illnesses or symptoms. At the end of the study, participants given the MVM supplement had increased their blood levels of vitamin C by 126% and zinc by 43%. There was no significant change in blood levels of vitamin D. There was no significant difference in the potential of blood to kill the introduced bacteria Staphylococcus aureus, or in neutrophil activity, nor were there any significant changes in blood levels of cytokines and chemokines. Participants taking the supplement did however report a shorter length, and lower severity of illnesses compared to those taking the placebo. The authors concluded that their findings support further research to test whether MVM supplementation can improve immune outcomes in older adults.
Abstract
Older adults are at increased risk for vitamin and mineral deficiencies that contribute to age-related immune system decline. Several lines of evidence suggest that taking a multi-vitamin and mineral supplement (MVM) could improve immune function in individuals 55 and older. To test this hypothesis, we provided healthy older adults with either an MVM supplement formulated to improve immune function (Redoxon® VI, Singapore) or an identical, inactive placebo control to take daily for 12 weeks. Prior to and after treatment, we measured (1) their blood mineral and vitamin status (i.e., vitamin C, zinc and vitamin D); (2) immune function (i.e., whole blood bacterial killing activity, neutrophil phagocytic activity, and reactive oxygen species production); (3) immune status (salivary IgA and plasma cytokine/chemokine levels); and (4) self-reported health status. MVM supplementation improved vitamin C and zinc status in blood and self-reported health-status without altering measures of immune function or status or vitamin D levels, suggesting that healthy older adults may benefit from MVM supplementation. Further development of functional assays and larger study populations should improve detection of specific changes in immune function after supplementation in healthy older adults.

Plain language summary
Coronavirus disease (Covid-19) continues to spread globally and to date there are no proven treatments. Current treatment focuses on the management of the associated acute respiratory distress syndrome (ARDS). There are many studies demonstrating that in severe sepsis and ARDS; Vitamin C reduces systemic inflammation, prevents lung damage, reduces the duration of mechanical ventilation (MV) and the length of intensive care unit (ICU) stay in patients. This is a case report where a critically ill patient received high-dose Vitamin C intravenous (IV) infusions and recovered. A 74 year-old woman with Covid-19, developed ARDS and septic shock. Usual medications were given. She needed MV and deteriorated rapidly. On Day 7 she was administered Vitamin C (11g per 24 hours as a continuous IV infusion). Her clinical condition improved slowly after this. In this case, high dose IV Vitamin C was associated with fewer days on mechanical intervention, a shorter ICU stay and earlier recovery. These results show the importance of further investigation of IV Vitamin C to assess its efficacy in critically ill Covid-19 patients requiring mechanical ventilation and ICU care.
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) continues to spread, with confirmed cases now in more than 200 countries. Thus far there are no proven therapeutic options to treat COVID-19. We report a case of COVID-19 with acute respiratory distress syndrome who was treated with high-dose vitamin C infusion and was the first case to have early recovery from the disease at our institute. CASE REPORT A 74-year-old woman with no recent sick contacts or travel history presented with fever, cough, and shortness of breath. Her vital signs were normal except for oxygen saturation of 87% and bilateral rhonchi on lung auscultation. Chest radiography revealed air space opacity in the right upper lobe, suspicious for pneumonia. A nasopharyngeal swab for severe acute respiratory syndrome coronavirus-2 came back positive while the patient was in the airborne-isolation unit. Laboratory data showed lymphopenia and elevated lactate dehydrogenase, ferritin, and interleukin-6. The patient was initially started on oral hydroxychloroquine and azithromycin. On day 6, she developed ARDS and septic shock, for which mechanical ventilation and pressor support were started, along with infusion of high-dose intravenous vitamin C. The patient improved clinically and was able to be taken off mechanical ventilation within 5 days. CONCLUSIONS This report highlights the potential benefits of high-dose intravenous vitamin C in critically ill COVID-19 patients in terms of rapid recovery and shortened length of mechanical ventilation and ICU stay. Further studies will elaborate on the efficacy of intravenous vitamin C in critically ill COVID-19.
