RESUMO

BACKGROUND: Vitamin D levels have been linked to certain pain states, including migraine. This study investigated whether vitamin D supplementation would be beneficial for adult patients with migraine (ClinicalTrials.gov Identifier: NCT01695460). METHODS: A randomized, double-blinded, placebo-controlled parallel trial was conducted in migraine patients (36 women and 12 men, 18-65 years of age). A 4-week baseline period was conducted before randomization to 24 weeks of treatment. Participants were assigned to receive D3-Vitamin (n = 24, 18 women and 6 men, 100 µg/day D3-Vitamin) or placebo (n = 24, 18 women and 6 men). Migraine attacks and related symptoms were assessed by self-reported diaries. The response rate (i.e. experiencing a 50% or greater reduction in migraine frequency from baseline to week 24), change in migraine severity, and number of migraine days were recorded. Changes in migraine-related symptoms, HIT-6TM scores, and pain sensitivity tests (pressure pain threshold and temporal summation) were also evaluated. Serum levels of both 25 (OH)D and 1,25 (OH)2D were assessed from baseline to week 24. RESULTS: The number of headache days changed from 6.14 ± 3.60 in the treatment group and 5.72 ± 4.52 in the placebo group at baseline to 3.28 ± 3.24 and 4.93 ± 3.24 by the end of the trial, respectively. Migraine patients on D3-Vitamin demonstrated a significant decrease (p < .001) in migraine frequency from baseline to week 24 compared with placebo. However, migraine severity, pressure pain thresholds, or temporal summation did not show a significant change. 25(OH)D levels increased significantly for the D3-Vitamin group during the first 12 weeks of treatment. There was no significant change in 1,25(OH)2D. No side-effects were reported or noted. CONCLUSIONS: D3-Vitamin was superior to placebo in reducing migraine days in migraine patients. Larger studies are required to confirm that vitamin D3 might be one of the prophylactic options for adult patients with migraine.

RESUMO

CONTEXT: Denosumab and zoledronic acid (ZOL) are parenteral treatments for patients with osteoporosis. OBJECTIVE: The objective of the study was to compare the effect of transitioning from oral bisphosphonates to denosumab or ZOL on bone mineral density (BMD) and bone turnover. DESIGN AND SETTING: This was an international, multicenter, randomized, double-blind trial. PARTICIPANTS: A total of 643 postmenopausal women with osteoporosis previously treated with oral bisphosphonates participated in the study. INTERVENTIONS: Subjects were randomized 1:1 to sc denosumab 60 mg every 6 months plus iv placebo once or ZOL 5 mg iv once plus sc placebo every 6 months for 12 months. MAIN OUTCOME MEASURES: Changes in BMD and bone turnover markers were measured. RESULTS: BMD change from baseline at month 12 was significantly greater with denosumab compared with ZOL at the lumbar spine (primary end point; 3.2% vs 1.1%; P < .0001), total hip (1.9% vs 0.6%; P < .0001), femoral neck (1.2% vs -0.1%; P < .0001), and one-third radius (0.6% vs 0.0%; P < .05). The median decrease from baseline was greater with denosumab than ZOL for serum C-telopeptide of type 1 collagen at all time points after day 10 and for serum procollagen type 1 N-terminal propeptide at month 1 and at all time points after month 3 (all P < .05). Median percentage changes from baseline in serum intact PTH were significantly greater at months 3 and 9 with denosumab compared with ZOL (all P < .05). Adverse events were similar between groups. Three events consistent with the definition of atypical femoral fracture were observed (two denosumab and one ZOL). CONCLUSIONS: In postmenopausal women with osteoporosis previously treated with oral bisphosphonates, denosumab was associated with greater BMD increases at all measured skeletal sites and greater inhibition of bone remodeling compared with ZOL.

RESUMO

BACKGROUND: The prognostic impact of tumour-promoting immune cells in cervical cancer is unclear. METHODS: Federation of Gynaecology and Obstetrics (FIGO) stage IB and IIA cervical cancer patients (N=101) were assessed for tumour-associated CD66b(+) neutrophils and CD163(+) macrophages by immunohistochemistry in whole tissue sections using stereology. Results were correlated with previous results on tumour-infiltrating CD3(+), CD4(+), and CD8(+) lymphocytes in the same cohort with recurrence-free survival (RFS) as end point. RESULTS: The highest densities of CD66b(+) neutrophils and CD163(+) macrophages were observed in the peritumoural compartment (median 53.1 cells mm(-2) and 1.3% area fraction, respectively). Above median peritumoural and stromal CD66b(+) neutrophils and peritumoural CD163(+) macrophages were significantly associated with short RFS. Multivariate analysis identified high peritumoural neutrophils (HR 2.27; 95% CI 1.09-4.75; P=0.03), low peritumoural CD8(+) lymphocytes (HR 3.67; 95% CI 1.63-8.25; P=0.002), and lymph node metastases (HR 2.70; 95% CI 1.26-5.76; P=0.01) as independent prognostic factors for short RFS, whereas CD163(+) macrophages were not significant. An index of combined intratumoral and peritumoral CD66b(+) neutrophils to CD8(+) lymphocytes had good discriminatory power for each quartile with 5-year RFS of 92%, 80%, 62%, and 44% (P=0.001). CONCLUSION: Tumour-associated neutrophil count is an independent prognostic factor for short RFS in localised cervical cancer. Combining CD66b and CD8 may further improve prognostic stratification. These findings require prospective validation.

RESUMO

CONTEXT: Treatment of osteoporosis with subcutaneous (SC) injections of rhPTH(1-34) or rhPTH(1-84) is associated with significant improvements in BMD and reductions in osteoporotic fractures. However, subcutaneous injections can be associated with discomfort and thus deteriorating compliance. OBJECTIVE: The UGL-OR1001 trial aimed to establish the efficacy and safety parameters of a novel oral tablet formulation of rhPTH(1-31)NH(2) and matching placebo tablets and open-label teriparatide positive control in postmenopausal women with osteoporosis. DESIGN: 24 weeks of randomized, double-blind treatment with once daily doses of 5mg oral treatment or corresponding placebo, or open-label subcutaneous teriparatide. PATIENTS OR OTHER PARTICIPANTS: Women diagnosed with postmenopausal osteoporosis as detected by lumbar spine DXA, with an exclusion of those with prior treatment with bone active agents. INTERVENTION(S): Orally formulated recombinant human PTH(1-31)NH(2) and placebo, or open-label subcutaneous teriparatide as a positive control. MAIN OUTCOME MEASURE(S): The primary endpoint was to characterize the percent change from baseline in bone mineral density (BMD) at L1-L4 axial lumbar spine after 24 weeks in the rhPTH(1-31)NH(2) arm. Secondary and exploratory endpoints included safety and tolerability of the oral formulation, measurement of biochemical markers of bone turnover, and evaluation of the PK profile at first and last dose. The study was registered at ClinicalTrials.gov with the identifier: NCT01321723. RESULTS: The oral tablet formulation of rhPTH(1-31)NH(2) resulted in similar PK profiles at both timepoints with mean C(max) values similar to subcutaneous administration. In the rhPTH(1-31)NH(2) arm, a 2.2% increase in lumbar spine BMD was observed compared to baseline (p<0.001), while no change was observed in the placebo arm. Open-label teriparatide resulted in a 5.1% increase in LS BMD (p<0.001). In the oral PTH study arm, the bone formation marker osteocalcin was increased by 32%, 21% and 23% at Weeks 4, 12 and 24, respectively. There was no significant increase in the level of the bone resorption marker CTx-1. CONCLUSIONS: In summary, these data demonstrate that enteric-coated oral tablet formulation technology consistently generated robust levels of exposure of rhPTH(1-31)NH(2) leading to induction of bone formation without inducing bone resorption resulting in significantly increased levels of LS BMD. Few adverse events were observed, recommending this orally delivered drug candidate for further development.

RESUMO

The purpose of this study was to investigate the prognostic value of the primary in situ cellular immune response in cervical squamous cell carcinoma. A study of 102 women treated for stage IB and IIA disease, between 1990 and 2000, was performed. Paraffin-embedded cervical tissue processed at the time of diagnosis was immunostained for CD3+ (T cells), CD4+ (T helper/regulatory T cells) and CD8+ (cytotoxic T cells) cells. Immune cell profile densities were estimated using stereology. Both intra- and peritumoural cell densities were estimated. Using Cox's proportional hazards regression modelling we found an increase in cell density to decrease the risk of relapse for all three cell types. The density of peritumoural CD3+ cells seems to have the strongest potential for predicting relapse. An increase in CD3+ cell density from 795 to 2043 cells per mm(2) (25-75 percentile) reduced the hazard ratio to 0.27.
