“Boswellia serrata
Description
Boswellia serrata (frankincense) is a moderate-to-large branching tree (growing to a height of 12 feet) found in India, Northern Africa, and the Middle East. Strips of Boswellia bark are peeled away, yielding a gummy oleo-resin. Extracts of this gummy exudate have been traditionally used in the Ayurvedic system of medicine as an antiarthritic, astringent, stimulant, expectorant, and antiseptic.”
Low vitamin D status has been associated with multiple sclerosis (MS) prevalence and risk, but the therapeutic potential of vitamin D in established MS has not been explored. Our aim was to assess the tolerability of high-dose oral vitamin D and its impact on biochemical, immunologic, and clinical outcomes in patients with MS prospectively.
An open-label randomized prospective controlled 52-week trial matched patients with MS for demographic and disease characteristics, with randomization to treatment or control groups. Treatment patients received escalating vitamin D doses up to 40,000 IU/day over 28 weeks to raise serum 25-hydroxyvitamin D [25(OH)D] rapidly and assess tolerability, followed by 10,000 IU/day (12 weeks), and further downtitrated to 0 IU/day. Calcium (1,200 mg/day) was given throughout the trial. Primary endpoints were mean change in serum calcium at each vitamin D dose and a comparison of serum calcium between groups. Secondary endpoints included 25(OH)D and other biochemical measures, immunologic biomarkers, relapse events, and Expanded Disability Status Scale (EDSS) score.
Forty-nine patients (25 treatment, 24 control) were enrolled [mean age 40.5 years, EDSS 1.34, and 25(OH)D 78 nmol/L]. All calcium-related measures within and between groups were normal. Despite a mean peak 25(OH)D of 413nmol/L, no significant adverse events occurred. Although there may have been confounding variables in clinical outcomes, treatment group patients appeared to have fewer relapse events and a persistent reduction in T-cell proliferation compared to controls.
High-dose vitamin D (~10,000 IU/day) in multiple sclerosis is safe, with evidence of immunomodulatory effects.
This trial provides Class II evidence that high-dose vitamin D use for 52 weeks in patients with multiple sclerosis does not significantly increase serum calcium levels when compared to patients not on high-dose supplementation. The trial, however, lacked statistical precision and the design requirements to adequately assess changes in clinical disease measures (relapses and Expanded Disability Status Scale scores), providing only Class level IV evidence for these outcomes.
Multiple sclerosis (MS) has a well-documented geographic distribution, with increasing prevalence and risk with increasing distance from the equator.1–4 Limited sunlight and UVB exposure, MS risk factors based on observational studies, are intermediaries between latitude and MS.2–5 Low serum 25(OH)D also appears to be a risk factor, and is a direct product of skin exposure to UVB.4–7
Patients with MS have relatively low serum 25(OH)D, with evidence that disease activity may increase when UVB exposure is limited.8–10 Additionally, increased sun exposure in early life significantly reduces disease development.5
In studies of vitamin D and calcium in experimental autoimmune encephalitis (EAE), preinduction treatment prevents disease development, while postinduction treatment ameliorates disease activity.11 Vitamin D has antiinflammatory actions in vitro, including enhanced Th2 and decreased Th1 cytokine production, dendritic cell effects, and enhanced macrophage phagocytosis.12
Vitamin D clearly has utility in MS prevention, but its role in established MS remains unknown. Observational studies have shown patients with MS respond to vitamin D and sun exposure.4–6,8–10,12 Physiologically, serum 25(OH)D acquired through sun exposure ranges up to 220 nmol/L with no recognized toxicity.13 Furthermore, patients with MS tolerated a pilot dose-escalation trial up to 40,000 IU/day.14
The present trial was undertaken to establish tolerability of high-dose vitamin D with calcium in a larger sample of patients with MS over 52 weeks. The hypothesis was that such doses are safe as measured by serum calcium over the dosing regimen. Secondary outcomes included serum parathyroid hormone (PTH), 25(OH)D, creatinine, transaminases, urinary calcium, relapses, disability (Expanded Disability Status Scale [EDSS]), T-cell reactivity, cytokines, and matrix-metalloproteinases.
The trial was approved by the institutional review boards at St. Michael’s Hospital (University of Toronto, Toronto, Canada) and McGill University (Montreal, Canada) and Health Canada for experimentation in human subjects. The trial was also registered with Clinicaltrials.gov through the National Institute of Health (ID NCT00644904). All patients provided written informed consent and were enrolled by the primary author.
Enrollment was limited to Multiple Sclerosis Clinic patients at St. Michael’s Hospital between June 2006 and March 2007, with the last patient completing the 52-week trial in March 2008. All patients were asked if they were interested in participating in any of the trials at the center for which they were eligible by clinic physicians. If patients were interested in the vitamin D trial, authors Dr. Burton or S. Kimball would speak with the patients at their request. Relapse assessments were performed by authors Dr. Burton and Dr. O’Connor.
Patients were eligible for inclusion if they were 18–55 years of age with clinically definite MS according to McDonald criteria and an EDSS score of 0–6.5.15,16 Patients could continue with their MS disease-modifying medication while in the trial, the monitoring of which was performed by authors Dr. Burton and Dr. O’Connor. Patients with the following were excluded: relapse within 60 days, steroid use within 30 days, chemotherapy within 12 months, pregnancy/inadequate contraception, vitamin D intake >4,000 IU/day, serum 25(OH)D level >150 nmol/L, lymphoma, granulomatous disease, cardiac arrhythmia, kidney dysfunction, or disordered calcium metabolism.
This was a phase I/II randomized open-label trial focusing on vitamin D safety. This design provides Class II level evidence for the primary outcome of serum calcium values across the treatment dosing regimen.
Patients were matched for age (18–30 years, 31–40 years, 41–55 years), disease duration (0–9 years, 10–19 years, ≥20 years), EDSS (≤2.5, 3.0–5.5, 6.0–6.5), and disease-modifying drug (interferon, glatiramer acetate, none). Members of pairs were randomized to treatment or control groups based on blinded drawing from a hat.
Treatment patients began calcium supplementation (1,200 mg) at visit 1 and initiated vitamin D 2 weeks later following the dosing regimen shown in table 1. Control patients were permitted to take ≤4,000 IU/day of vitamin D and supplemental calcium if desired.
All patients had EDSS and general medical examinations at baseline and end of the trial. Serum calcium, albumin, 25(OH)D, PTH, transaminases (alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [ALP]), creatinine, urea and urinary calcium/creatinine ratios were measured in treatment patients at all visits. Treatment patients were seen every 6 weeks for the above testing and to obtain subsequent doses of vitamin D. Renal ultrasounds to monitor for calcifications were performed at baseline and weeks 29 and 52, while EKGs were performed at baseline and week 52. Serum was drawn and cryopreserved for cytokine analysis and matrix metalloproteinase-9 (MMP-9)/tissue inhibitory of metalloproteinase-1 (TIMP-1) in all patients while fresh blood was drawn at baseline and week 52 for T-cell assays. Control patients had 25(OH)D and calcium/albumin levels and T-cell reactivity testing at weeks 1 and 52, while MMP-9/TIMP-1 and cytokines were assessed at weeks 1, 11, 29, and 52 (see table e-1 on the Neurology® Web site at www.neurology.org for schedule).
Patients experiencing relapse (defined as an objective new/reemerging neurologic abnormality present for at least 24 hours in the absence of fever/infection) or adverse events were seen within 72 hours by the treating physician. Patients experiencing relapse events received steroids (IV methylprednisolone or oral prednisone) as deemed appropriate by the treating physician. All events were documented on adverse event reporting forms.
The preparation and quality testing of ethanol solutions of vitamin D has been previously described.14 Hyperconcentrated solutions were supplied in amber glass vials at every dose-changing visit. Patients were instructed to take anywhere between 1 and 4 mL/wk orally (depending on that week’s concentration) to achieve the desired dose, but only after serum calcium and urinary calcium/creatinine measured at that time were found to be within normal limits. Patients also received tricalcium phosphate powder and were instructed to take a measured amount equivalent to 1,200 mg/day by mouth. Consistent failure of 25(OH)D to increase with increasing dose was taken as evidence of possible noncompliance.
Peripheral blood T-cell proliferative responses to a panel of 13 MS-related and dietary antigens and 4 control test antigens were measured as previously described.17 For comparisons over time and among groups, a T-cell score (TCS) was generated from the number of positive responses to these antigens.
Serum levels of matrix metalloproteinases (MMP-9 and TIMP-1) were measured with the Quantikine ELISA system (R&D Systems Inc., Minneapolis, MN) according to manufacturer’s directions. MMP-9, TIMP-1, and MMP-9/TIMP-1 were evaluated at weeks 1, 11, 29, and 52 in all patients.
Cytokine samples were drawn from serum and from the supernatant of the T-cell proliferation assays at baseline and end of trial in all patients, and in the treatment group patients at weeks 2 and 11 to reduce statistical error. Cytokine concentrations (interleukin [IL]-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12p40, IL-13, interferon-γ, and tumor necrosis factor–α [TNFα]) were measured simultaneously by multiplex bead immunoassays and read on the Luminex LX100 as previously described.18
All analyses assumed a 2-sided test of hypothesis with an overall α value of 0.05. Immunologic end points and post hoc analyses, which included all time points, were considered exploratory and were not adjusted for multiple comparisons. Descriptive statistics were presented as means with SD. Nonparametric tests were used to compare characteristics between treatment groups.
Sample size was based on a power of 0.90 at a 2-sided 0.05 significance level, if the true difference between the treatment and control groups was 1 SD. This would have been a clinically meaningful increase in the calcium-related measures most likely to be adversely affected by the vitamin D including renal and hepatic markers. A sample of 60 patients provided >0.90 power with an α of 0.05 for the primary meaningful effect size of a 0.30 mmol/L difference in serum calcium (α of 0.05).
For outcomes, sign/sign rank tests were used to evaluate continuous outcomes. McNemar testing was used to analyze categorical and binary outcomes while repeated measures were calculated using mixed modeling procedures and time series analysis. For nonparametric testing on unpaired continuous data, the Wilcoxon rank sum test was used. All statistical tests were performed using SAS 9.1.3™.
Between June 2006 and March 2007, 51 patients were screened and 49 matched for age, disease duration, EDSS, and disease-modifying drug (25 treatment, 24 control). Due to feasibility constraints, enrollment was stopped at 51 subjects, but this still provided >0.90 power for the primary endpoint and was approved by the institutional review boards at participating centers. Baseline demographics are outlined in table 2. Three subjects did not have exact matches. Forty-five patients had relapsing-remitting MS and 4 had secondary progressive MS. Forty women and 9 men participated. The mean age of all subjects was 40.5 years (21–54), with mean EDSS 1.34 (0–6.0) and disease duration of 7.8 years (1–25). At trial entry, mean baseline calcium was 2.32 mmol/L (2.08–2.57) and mean was 25(OH)D 78 nmol/L (38–154). There were no differences between groups for these or any baseline characteristics including pretrial vitamin D intake and relapse rate. Two patients in each group withdrew during the trial, none related to adverse events (figure 1).
The primary outcome, serum calcium at each dose in the treatment regimen, was evaluated by repeated measures/mixed modeling procedures. The influence of season was ruled out using time series analysis. No significant difference in serum calcium occurred at any point along the dosing regimen, nor did any serum calcium values exceed the upper limit of the reference range (2.10–2.60 mmol/L) (figure 2, A and B).
Urinary calcium was evaluated in a similar manner, and during the weeks at the highest doses of vitamin D (weeks 17–29), urinary calcium/creatinine ratios rose to a maximum mean of 0.61 (mixed modeling least squares [LS] means, p = 0.014), but always below the cutoff of 1.0 (figure 2C). PTH varied significantly over the trial, but within the normal range (1.3–5.4 pmol/L) and not influenced by vitamin D dose (mixed modeling LS means, p = 0.02) (table e-2).
As expected, serum 25(OH)D rose considerably, reaching a maximum mean of 413 nmol/L following the 40,000 IU/day dosing period. This value is well above the cited “toxic” value of 250 nmol/L.13 In fact, patient mean serum 25(OH)D values were above this threshold for over 18 weeks with no adverse consequences (figure 2D).
Renal and hepatic function was assessed by creatinine/urea and ALT/AST/ALP at all visits in the treatment group. There were no cases of disordered creatinine, urea, ALT, AST, or ALP (table e-2).
No patient had evidence of renal calcification on ultrasound. Incidental chronic pelviectasis was found in one asymptomatic patient without nephrolithiasis. Another patient had preexisting chronic hemangiomas while a third had transient fatty liver attributed to recent steroid therapy. No disturbances of cardiac rhythm were seen.
As this trial was unblinded, all clinical results are exploratory and subject to bias. Mean annualized relapse rate in treatment patients decreased from 0.44 to 0.26, while in control patients, it also decreased, from 0.54 to 0.45, although this was not significant by sign test (table 3). The proportion of treatment patients experiencing relapses during the trial was 0.16 vs 0.37 in the control group (McNemar, p = 0.09). Some trends favoring the treatment group were seen in EDSS measures, but the majority of patients had low EDSS scores throughout the trial with changes typically of 0.5 to 1 EDSS point (table 3).
T-cell proliferative responses were compared at the first and final visits, 52 weeks apart, in all patients. The total TCS, a tally of the number of positive proliferative responses over the trial in response to antigenic stimulation, decreased significantly in the treatment group (sign test, p = 0.002), with no change in controls. The proportion of patients who completed the trial with a total TCS below the predetermined threshold of 4 was greater in the treatment group (McNemar, p = 0.052). When comparing those who completed the trial with a 25(OH)D level = >100 nmol/L to those with values <100 nmol/L, a significantly larger proportion of those with decreased TCS was seen in those with levels ≥100 nmol/L (Wilcoxon rank sum test, p = 0.032).
Repeated measurements of MMP-9 and its inhibitor TIMP-1 over 4 time points during the trial revealed small reductions between visits over the course of the trial in both treatment and control groups. Neither magnitude nor direction of change differed significantly between groups.
Cytokine measures were carried out in duplicate, and the mean of these measures was used in all subsequent analyses. Analysis for IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12p40, IL-13, interferon-γ, and TNFα was carried out in both serum samples collected at the indicated time points, as well as in supernatants of the lymphocyte response assay samples described above. There were no consistent patterns of change in cytokine titers within or between groups over the 52-week period (data not shown).
A separate report by this group on the immunologic outcomes is currently in preparation.
No adverse events with the use of vitamin D were reported. Four treatment patients experienced mild constipation early in the trial attributed to calcium supplementation in powdered form. All symptoms resolved with calcium formulation change or discontinuation.
We have demonstrated that high-dose oral vitamin D in patients with MS, at doses resulting in serum 25(OH)D concentrations approximately double the physiologic rage obtainable by UV exposure, did not result in clinical, biochemical, or radiologic adverse events.13 Neither hypercalcemia nor persistent hypercalciuria occurred, nor did any disruption in renal or hepatic function. Treated patients spent 36/52 weeks on doses of 10,000 IU/day of VD3 or greater, with a mean daily dose of roughly 14,000 IU/day, reaching a mean peak of serum 25(OH)D >400 nmol/L.
The trial was not powered nor blinded to properly address clinical outcomes, but we did observe that clinical outcomes appeared to favor the treatment group.
T-cell reactivity and proliferation dropped significantly in treatment patients over the 52-week period, while no change was seen in controls. This decrease was most pronounced in patients who maintained a 25(OH)D level ≥100 nmol/L at 52 weeks. While long-term treatment of larger cohorts is required to seek relationships between clinical course improvements and T-cell reactivity, the latter observation may provide a first, tentative target range for therapeutic serum 25(OH)D levels in patients with MS. Unfortunately, measurement of more surrogate markers of proinflammatory and antiinflammatory markers in serum and T-cell culture supernatants disappointed. MMP-9/TIMP-1 values changed over the trial, but the nature and magnitude of change did not differ between groups, and cytokine profiles did not yield meaningful patterns of change under trial conditions. The explanation for these outcomes may ultimately be the true lack of impact of VD3 on such markers or confounding supplementation use with vitamin D or other agents in controls, but may also be related to methodologic limitations including power, regression to the mean, or degradation of sample integrity after prolonged cryopreservation. Additionally, changes in these markers may occur over much briefer time periods or to a much smaller extent than could be detected, and were missed.
Unlike earlier trials using low-dose vitamin D or calcitriol in MS, our trial used high-dose vitamin D (the direct product of UVR exposure of human skin), and was the first controlled trial to test the safety of such high doses over an extended period of time.19,20 A major strength was the novel titration schedule used, minimizing the risk of toxicity at higher doses because doses were only increased after the safety of preceding doses was confirmed. As well, the addition of calcium supplementation allowed safety data to be generalized to those already on calcium supplementation, and the combination of vitamin D and calcium appears most effective in both EAE models and human cancer prevention trials.11,18 The present trial’s sample size provided sufficient power for primary endpoints of safety measures, namely serum calcium levels, and the use of vitamin D (cholecalciferol) provided additional safety from hypercalcemia, as this inactive precursor of the hormonal metabolite, calcitriol, has low calcemic potential.19,20 An earlier trial of calcitriol in MS led to several instances of hypercalcemia.19,20
Our trial, however, is not without limitations. The matching design limited patient enrollment and recruitment duration, and selection and volunteer bias cannot be ruled out. Although the primary outcomes (serum calcium values) were not vulnerable to a lack of blinding, clinical outcomes certainly may have been. More frequent monitoring of the treatment group could have been a factor in the disclosure of relapses and may have missed possible events or use of undisclosed agents in the less frequently assessed control group.21 Furthermore, changes in EDSS were admittedly typically no greater than 0.5 to 1 point, and in a group with a relatively low EDSS at baseline. Additionally, while more robust results may have been seen had the control group not taken any vitamin D, such restrictions were deemed unethical.
We have demonstrated that vitamin D intake well above current recommendations, and 25(OH)D levels beyond the physiologic range, do not expose patients with MS to adverse biochemical or clinical events. Compared to a control group whose intake of vitamin D generally exceeded the current North American recommendations, only those on the treatment regimen had evidence of immunologic effects. Whether toxicity emerges upon longer exposures remains to be established, but the trial identified achievable, nontoxic target levels of serum 25(OH)D that may be sufficient to impact inflammatory activity. If, as supported by previous studies and the present trial, vitamin D promotes a shift away from T-cell proliferation and proinflammatory activity, there is reason to hypothesize that vitamin D could potentially reduce the inflammatory activity complicit in relapses and the neuronal damage implicated in disability and progression. Our results provide preliminary evidence to support studying this hypothesis. Certainly it appears that in the case of MS, a “normal” 25(OH)D level may not be optimal or sufficient to derive benefit at the immunologic level.
Development of a multicenter, randomized, blinded, controlled phase II proof-of-concept trial, powered for MRI and clinical outcomes, is presently underway and is likely the only way to truly define the impact of vitamin D on outcomes meaningful to patients with MS.

Abstract
The purpose was to investigate the relationship between anxiety, depression, and quality of life in patients with glaucoma. This case-control study was carried out with 121 participants with glaucoma (M age=64.2, SD=13.2; 68 women, 76.0% married) and 64 controls. The data were collected by using a data collection form involving questions on patients’ specific characteristics, the Hospital Anxiety and Depression Scale, and the National Eye Institute Visual Function Questionnaire. Rate of clinical anxiety was 14.0% and depression 57.0% among the participants with glaucoma. The anxiety risk in women with glaucoma was found to be 7.5 times higher than in men. Risk of depression was 2.94 times higher in unmarried compared to married participants. Anxiety scores were higher in unmarried participants and women. The mean Depression score was statistically significantly higher for unmarried participants. The incidence of depression and anxiety increased with decreasing quality of life scores. Quality of life was associated negatively with anxiety and depression in patients with glaucoma. Evaluating quality of life, anxiety, and depression in older individuals who have glaucoma and examining the risk factors are important to provide earlier health care service and preventive psychological treatment.
