Background: Vitamin D might be promising to serve as an adjunctive therapy for pulmonary tuberculosis (TB). However, the results remained controversial. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of vitamin D in patients with pulmonary TB. Methods: Medline, SCOPUS, Google Scholar, EMBASE, Springer, and Science Direct were searched electronically from inception to Oct 2016. Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) assessing the effect of vitamin D plus anti-tuberculosis treatment (ATT) versus placebo plus ATT on the treatment of pulmonary TB were included...

The role of vitamin D in tuberculosis (TB) has been a hot topic for decades, and it is still an unresolved matter. Vitamin D deficiency and other micronutrient deficiencies have been considered as important risk factors for TB and malnutrition is overall a highly important risk factor for TB. In fact with the highest population attributable fraction (PAF) for TB at 27% (1), which means the fraction of all TB cases that would NOT have occurred if exposure (to e.g. malnutrition) was not there.

Low vitamin D (vitD₃) is one of the most common nutritional deficiencies in the world known to be associated with numerous medical conditions including infections such as tuberculosis (TB). In this study, vitD₃ status and its association with the antimicrobial peptide, human cathelicidin (LL-37), was investigated in Ethiopian patients with different clinical forms of TB. Patients with active TB ( n = 77) and non-TB controls ( n = 78) were enrolled in Ethiopia, while another group of non-TB controls ( n = 62) was from Sweden...

Background Vitamin D is an immunomodulator, and its deficiency is associated with tuberculosis (TB) infection. Bronchoalveolar lavage fluid (BALF) is a rich milieu of macrophages that forms the first line of defense against invading TB bacilli. Because there is an increased prevalence of vitamin D deficiency in TB and human-immunodeficiency virus-1 (HIV-1) subjects, we intend exploring the possibility of a localized deficiency of vitamin D metabolites in BALF of these patients. OBJECTIVE: The primary objective was to assess the level of 25D3 in serum and BALF of subjects and look for a significant difference among patients and controls...

Tuberculosis (TB) has troubled mankind for millennia, but current treatment strategies are long and complicated and the disease remains a major global health problem. The risk of Mycobacterium tuberculosis (Mtb) infection or progression of active TB disease is elevated in individuals with vitamin D deficiency. High-dose vitamin D was used to treat TB in the pre-antibiotic era, and in vitro experimental data show that vitamin D supports innate immune responses that restrict growth of Mtb. Several randomised controlled trials have tested whether adjunctive vitamin D supplementation enhances the clinical and microbiological response to standard antimicrobial chemotherapy for pulmonary TB...

BACKGROUND: The inherent risk of developing tuberculosis (TB) in HIV- infected individuals is further enhanced by hypovitaminosis D. Interventions that offset HIV-associated immune deterioration potentially arrest disease progression and incidence of opportunistic infections including TB. Despite conflicting reports on association between vitamin D deficiency (VDD) and risk of TB, vitamin D (VD) supplementation remains a promising intervention. METHODS: We conducted a comparative cross-sectional study on 145 HIV+ /pulmonary TB+ (PTB) and 139 HIV+ /PTB- hospitalised patients to investigate association of vitamin D status and risk of PTB...

Development of Mycobacterium tuberculosis (Mtb) infection depends on the ability of the host to elicit the protective immune response to the pathogen. Cathelicidin plays a role in antibacterial innate immunity mechanisms. This peptide contributes to the barrier function of respiratory epithelium and takes part in controlling pulmonary bacterial infections. LL-37 (leucine-leucine-37) is involved in host defense and innate immune response to mycobacterial infections, as well. This study aims to evaluate the serum concentrations of LL-37 in individuals with active pulmonary tuberculosis (TB) and to determine whether any correlations between peptide LL-37, tumor necrosis factor (TNF) and vitamin D serum levels exist...

There is little research on how individuals suffering from tuberculosis may differ from those not infected in terms of overall skeletal morphology. Tuberculosis was endemic in 19th and early 20th century Finland making documented skeletal collections of Finns ideal to study effects of the disease on bone. The present study compares long bone cross-sectional total area between individuals who died of tuberculosis and those with another recorded cause of death in a Finnish sample. Adult male individuals (N = 105) were selected for analysis...

Poor vitamin D status has been associated with tuberculosis (TB); whether poor status is cause or consequence of disease is uncertain. We conducted a case-control study and two nested case-control studies to determine whether vitamin D levels were associated with active TB, tuberculin skin test (TST) conversion, and risk of progression to the active TB in prisoners in Brazil. In multivariable conditional logistic regression, subnormal vitamin D levels (OR, 3.77; 95% CI, 1.04-13.64) were more likely in prisoners with active TB...

Purpose of review With established immunosuppressant treatment regimens for anti-neutrophil cytoplasm antibody-associated vasculitides (AAV), prognosis has significantly improved. The mainstay of treatment still comprises high-dose corticosteroids and cyclophosphamide for severe forms, although rituximab is being increasingly utilised instead of cyclophosphamide as induction therapy. AAV patients experience an excess of infections, malignancies and cardiovascular events as compared to the general population, which is a combination of the systemic inflammatory process associated with vasculitis and the adverse events from treatment...

Worldwide, tuberculosis (TB) is still a serious and significant health concern, more so with the emergence of multidrug-resistant-TB. The inability of mankind to control this infection stems from the fact that the vaccines and drugs that were once effective against TB are no longer efficacious. This has led to a search for new antituberculous agents and adjuvant therapy. Vitamins are being revisited for their role in pathogenicity as well as for their antimycobacterial properties. Vitamins such as biotin and thiamin are essential for Mycobacterium tuberculosis and are required for establishment of infection...

Tuberculosis (TB), caused by Mycobacterium tuberculosis ( Mtb ), remains a leading cause of morbidity and mortality in humans worldwide. Currently, the standard treatment for TB involves multiple antibiotics administered for at least 6 months. Although multiple antibiotics therapy is necessary to prevent the development of drug resistance, the prolonged duration of treatment, combined with toxicity of drugs, contributes to patient non-compliance that can leads to the development of drug-resistant Mtb (MDR and XDR) strains...
