The results showed that vitamin D levels were much lower in COVID-19 patients than in the healthy control group. The lowest vitamin D levels were found in the most severe…

Vitamin D reduces the need for ICU treatment

Summary This study measured the effects of vitamin D supplementation on Intensive Care Unit Admission and death rate among 76 hospitalized COVID-19 patients. The supplementation of a high dose of vitamin D showed that the need for Intensive Care Unit Treatment decreased and reduced the severity of the disease. Further details can be found in…

Vitamin A deficiency is associated with tuberculosis

Summary In this study the association between vitamin A deficiency and tuberculosis was investigated. 300 participants were categorized as mild tuberculosis and severe tuberculosis. The results showed that severe tuberculosis was associated with vitamin A deficiency. Further details can be found in the study.

Micronutrients improve tuberculosis therapy

Summary Micronutrient deficiency is a key factor in the progression of tuberculosis. Based on this understanding, the present study evaluated the effect of a micronutrient supplementation, including vitamin A, B, C, E and selenium, in adults with tuberculosis. 471 adults infected with human immunodeficiency virus (HIV) and 416 HIV-negative adults with tuberculosis were investigated. The…

Green tea extract inhibits Mycobacterium tubercolosis

Summary This study evaluated the effects of epigallocatechin gallate (EGCG, the main component of green tea) and triclosan (antibacterial agent) against Mycobacterium tuberculosis, the bacterium that causes tuberculosis. The experiments showed that EGCG inhibited Mycobacterium tuberculosis and increased the inhibitory activity of triclosan against this bacterium. More details can be found in the study. References…

Vitamin D accelerates tuberculosis recovery

Summary This study evaluated the effect of vitamin D on tuberculosis, as indicated by “sputum culture conversion”, i.e. an analysis showing that a patient is cured of tuberculosis. 146 patients with tuberculosis were given either vitamin D or no supplementation. The results showed that vitamin D administration hastened recovery from tuberculosis. Further details can be…

Blood levels of antioxidants are reduced in tuberculosis patients

Summary This study evaluated the blood levels of antioxidants (vitamins C, E and glutathione) in tuberculosis patients and healthy persons. Reduced levels of antioxidants were found in tuberculosis patients who, consequently, were more susceptible to oxidative stress, which is an imbalance between the production of free radicals and the body´s antioxidant defences. More details can…

Vitamin E reduces the risk of stone formation in tuberculosis patients

Summary This study analysed oxidative stress – the imbalance between the production of free radicals and the body´s ability to counteract their harmful effects through antioxidants – in tuberculosis patients, which is a predisposing factor for renal stone formation. Patients were divided in four groups: healthy people, tuberculosis patients a day before treatment, tuberculosis patients…
