Abstract
BACKGROUND Growing evidence suggests that vitamin D deficiency might be implicated in the development of active tuberculosis (TB). We evaluated vitamin D levels in children with active TB compared to children with latent TB infection (LTBI), non-TB pneumonia (NTBP) and healthy controls to determine if there was a difference. METHODS In this prospective study, vitamin D levels were measured and compared between the four groups and adjusted for age, ethnicity, gender and season of sample collection. RESULTS Fifty-seven children were included: 24.6% active TB, 28.1% LTBI, 22.8% NPTB and 24.6% healthy controls. 36.8% of all children tested had an insufficient or deficient vitamin D level. Vitamin D level was significantly lower in active TB compared to other groups (p = 0.004). CONCLUSIONS Our study showed a correlation between hypovitaminosis D and active pulmonary TB.

Abstract
OBJECTIVE Immunotherapy using vitamin D (vitD3 ) and phenylbutyrate (PBA) may support standard drug regimens used to treat infectious diseases. We investigated if vitD3 + PBA enhanced clinical recovery from pulmonary tuberculosis (TB). METHODS A randomized controlled trial was conducted in Addis Ababa, Ethiopia. Patients with smear-positive or smear-negative TB received daily oral supplementation with 5000 IU vitD3 and 2 × 500 mg PBA or placebo for 16 weeks, together with 6-month chemotherapy. Primary end-point: reduction of a clinical composite TB score at week 8 compared with baseline using modified intention-to-treat (mITT, n = 348) and per-protocol (n = 296) analyses. Secondary end-points: primary and modified TB scores (week 0, 4, 8, 16, 24), sputum conversion, radiological findings and plasma 25(OH)D3 concentrations. RESULTS Most subjects had low baseline plasma 25(OH)D3 levels that increased gradually in the vitD3 + PBA group compared with placebo (P < 0.0001) from week 0 to 16 (mean 34.7 vs. 127.4 nmol L-1 ). In the adjusted mITT analysis, the primary TB score was significantly reduced in the intervention group at week 8 (-0.52, 95% CI -0.93, -0.10; P = 0.015) while the modified TB score was reduced at week 8 (-0.58, 95% CI -1.02, -0.14; P = 0.01) and 16 (-0.34, 95% CI -0.64, -0.03; P = 0.03). VitD3 + PBA had no effect on longitudinal sputum-smear conversion (P = 0.98). Clinical adverse events were more common in the placebo group (24.3%) compared with the vitD3 + PBA group (12.6%). CONCLUSION Daily supplementation with vitD3 + PBA may ameliorate clinical TB symptoms and disease-specific complications, while the intervention had no effect on bacterial clearance in sputum.

Abstract
The already enormous burden caused by tuberculosis (TB) will be further aggravated by the association of this disease with modern epidemics, as human immunodeficiency virus and diabetes. Furthermore, the increasingly aging population and the wider use of suppressive immune therapies hold the potential to enhance the incidence of TB. New preventive and therapeutic strategies based on recent advances on our understanding of TB are thus needed. In particular, understanding the intricate network of events modulating inflammation in TB will help to build more effective vaccines and host-directed therapies to stop TB. This review integrates the impact of host, pathogen, and extrinsic factors on inflammation and the almost scientifically unexplored complexity emerging from the interactions between these three factors. We highlight the exciting data showing a contribution of this troika for the clinical outcome of TB and the need of incorporating it when developing novel strategies to rewire the immune response in TB.

Polymorphisms in the vitamin D receptor gene are associated with reduced rate of sputum culture conversion in multidrug-resistant tuberculosis patients in South Africa. PLoS One 2017; 12:e0180916. [PMID: 28700743 PMCID: PMC5507304 DOI: 10.1371/journal.pone.0180916] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Accepted: 06/22/2017] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Vitamin D modulates the inflammatory and immune response to tuberculosis (TB) and also mediates the induction of the antimicrobial peptide cathelicidin. Deficiency of 25-hydroxyvitamin D and single nucleotide polymorphisms (SNPs) in the vitamin D receptor (VDR) gene may increase the risk of TB disease and decrease culture conversion rates in drug susceptible TB. Whether these VDR SNPs are found in African populations or impact multidrug-resistant (MDR) TB treatment has not been established. We aimed to determine if SNPs in the VDR gene were associated with sputum culture conversion among a cohort of MDR TB patients in South Africa. METHODS We conducted a prospective cohort study of adult MDR TB patients receiving second-line TB treatment in KwaZulu-Natal province. Subjects had monthly sputum cultures performed. In a subset of participants, whole blood samples were obtained for genomic analyses. Genomic DNA was extracted and genotyped with Affymetrix Axiom Pan-African Array. Cox proportional models were used to determine the association between VDR SNPs and rate of culture conversion. RESULTS Genomic analyses were performed on 91 MDR TB subjects enrolled in the sub-study; 60% were female and median age was 35 years (interquartile range [IQR] 29-42). Smoking was reported by 21% of subjects and most subjects had HIV (80%), were smear negative (57%), and had cavitary disease (55%). Overall, 87 (96%) subjects initially converted cultures to negative, with median time to culture conversion of 57 days (IQR 17-114). Of 121 VDR SNPs examined, 10 were significantly associated (p<0.01) with rate of sputum conversion in multivariable analyses. Each additional risk allele on SNP rs74085240 delayed culture conversion significantly (adjusted hazard ratio 0.30, 95% confidence interval 0.14-0.67). CONCLUSIONS Polymorphisms in the VDR gene were associated with rate of sputum culture conversion in MDR TB patients in this high HIV prevalence setting in South Africa.

Abstract
BACKGROUND Vitamin D is recognised to have multiple actions, including role in immune modulation. The prevalence and impact of vitamin D deficiency (VDD) in abdominal tuberculosis is unknown. METHODS We report the prevalence and clinical impact of VDD in patients with abdominal tuberculosis. The patients were divided into two groups: VDD (<20 ng/ml) or vitamin D sufficient (VDS) (⩾20 ng/ml). Groups were compared for extent (abdominal alone or extra-abdominal also) of disease and pattern of involvement (intestinal, peritoneal or both) and inflammatory response [serum C-reactive protein (CRP)]. RESULTS Of 63 patients, 53 had complete data (mean age: 36.3 ± 14.43, 31 males). Fourty-five (84.9%) patients had VDD and mean VD levels were 11.1 ± 10.1 ng/ml. Of 8 patients with VDS, 1 (12.5%) had extra-abdominal involvement while 13 (28.9%) with VDD had extra-abdominal involvement (p = 0.066). The mean CRP in patients with VDD was 42.9 ± 34.9 mg/dl vis-a-vis 105.38 ± 64.8 in VDS (p ⩽ 0.05). All seven patients with both intestinal and peritoneal involvement had VDD. CONCLUSION VDD is common in abdominal tuberculosis and may be associated with more extensive involvement albeit a reduced inflammatory response.

Abstract
Although tuberculosis is largely a curable disease, it remains a major cause of morbidity and mortality worldwide. Although the standard 6-month treatment regimen is highly effective for drug-susceptible tuberculosis, the use of multiple drugs over long periods of time can cause frequent adverse drug reactions. In addition, some patients with drug-susceptible tuberculosis do not respond adequately to treatment and develop treatment failure and drug resistance. Response to tuberculosis treatment could be affected by multiple factors associated with the host-pathogen interaction including genetic factors and the nutritional status of the host. These factors should be considered for effective tuberculosis control. Therefore, therapeutic drug monitoring (TDM), which is individualized drug dosing guided by serum drug concentrations during treatment, and pharmacogenetics-based personalized dosing guidelines of anti-tuberculosis drugs could reduce the incidence of adverse drug reactions and increase the likelihood of successful treatment outcomes. Moreover, assessment and management of comorbid conditions including nutritional status could improve anti-tuberculosis treatment response.
