Impact of a Pharmacist-Led Hypertension Management Program for Oral Chemotherapy in a Specialty Pharmacy Setting.

INTRODUCTION: Oral chemotherapy agents are a growing area of oncology treatment, but some are associated with a high incidence of hypertension. Management of hypertension in oncology patients may be insufficient due to a variety of reasons. A pharmacist-led hypertension management service within the specialty pharmacy setting has the potential to help patients on oral chemotherapy achieve and maintain adequate blood pressure control. The objective of this study was to assess the impact of a pharmacist-led hypertension management program on the blood pressure control of patients on oral chemotherapy. METHODS: This retrospective, single-center study compared data from two groups of patients receiving oral chemotherapy agents from a health systems specialty pharmacy within an academic medical center, before and after the establishment of a pharmacist-led hypertension management program. RESULTS: Twenty-one of 50 (0.42) patients in the control group had blood pressure overall at goal, compared to 19 of 29 (0.66) patients in the intervention group who had blood pressures at goal at the end of the specified 3-month time period (p = 0.04). In cases where a pharmacist intervention was necessary per the hypertension management program's protocol, the rate of provider acceptance of recommendations regarding modifying or initiating antihypertensive therapy was high. CONCLUSION: When followed with a pharmacist-led hypertension management program, patients on oral chemotherapy showed improved blood pressure control and reduced mean blood pressure readings over time.

IBD Serology and Disease Outcomes in African Americans With Crohn's Disease.

Backgrounds: Recent studies have identified the role of serologic markers in characterizing disease phenotype, location, complications, and severity among Northern Europeans (NE) with Crohn's disease (CD). However, very little is known about the role of serology in CD among African Americans (AA). Our study explored the relationship between serology and disease phenotype in AA with CD, while controlling for genetic ancestry. Methods: AAs with CD were enrolled as participants through multicenter collaborative efforts. Serological levels of IgA anti-Saccharomyces cervisiae antibody (ASCA), IgG ASCA, E. coli outermembrane porin C, anti-CBir1, and ANCA were measured using enzyme-linked immunosorbent assays. Genotyping was performed using Illumina immunochip technology; an admixture rate was calculated for each subject. Multiple imputation by chained equations was performed to account for data missing at random. Logistic regression was used to calculate adjusted odds ratio (OR) for associations between serological markers and both complicated disease and disease requiring surgery. Results: A total of 358 patients were included in the analysis. The majority of our patients had inflammatory, noncomplicated disease (58.4%), perianal disease (55.7%), and documented colonic inflammation (86.8%). On multivariable analysis, both IgG ASCA and OmpC were associated with complicated disease (OR, 2.67; 95% CI, 1.67-4.28; OR, 2.23; 95% CI, 1.41-3.53, respectively) and disease requiring surgery (OR, 2.51; 95% CI, 1.49-4.22; OR, 3.57; 95% CI, 2.12-6.00). NE admixture to the African genome did not have any associations or interactions in relation to clinical outcome. Conclusions: Our study comprises the largest cohort of AAs with CD. The utility of serological markers for the prognosis of CD in NE applies equally to AA populations.

Phase coarsening in multicomponent systems.

A theory for phase coarsening in multicomponent systems is developed in which both the multicomponent thermodynamic effect and kinetic effect from a nonzero volume fraction are considered. In contrast to previous theory, a diffusion screening zone for a coarsening particle due to nonzero volume fraction is introduced. The evolution equation for phase coarsening in multicomponent systems is derived in a rigorous way in the framework of the maximum rate of dissipation with the constraints of mass and energy conservation. Existing previous relations are recovered and generalized. Some findings such as the relationship between the maximum particle size and volume fraction and particle size distribution in multicomponent systems are discovered.

Case-control Association Study of Autoimmunity Associated Variants in PDCD1 and Juvenile Idiopathic Arthritis.

PURPOSE: Variants in the gene encoding Programmed Cell Death-1 (PDCD1) have been associated with susceptibility to Systemic Lupus Erythematosus and other autoimmune diseases. Given that clinically distinct autoimmune phenotypes share common genetic susceptibility factors, variants in PDCD-1 were tested for a possible association with Juvenile Idiopathic Arthritis (JIA). METHODS: Four Single Nucleotide Polymorphisms (SNPS) in the PDCD1 gene were genotyped and analyzed: rs7421861, rs11568821, rs10204525, and rs7568402 in 834 cases and 855 controls of Northern European ancestry. Each variant was examined for possible associations with JIA and then analyzed for association with JIA categories. RESULTS: PDCD1 variants showed no association with JIA in the cohort overall (rs7421861 p=0.63, rs11568821 p=0.13, rs10204525 p=0.31, and rs7568402 p=0.45). Stratification by JIA categories indicated a significant association between systemic JIA and PDCD1 rs7568402 (OR=0.53, p=0.0027), which remained significant after 10,000 permutations, but was not replicated in an independent multi-ethnic systemic JIA cohort. A nominal association between enthesitis-related arthritis and rs115668821 was also observed (OR=0.22, p=0.012). CONCLUSION: Unlike other multiple autoimmune disease associated genetic variants, there was no association between PDCD1 variants and JIA or JIA categories.

Symptoms of periodontitis and antibody responses to Porphyromonas gingivalis in juvenile idiopathic arthritis.

BACKGROUND: The association between rheumatoid arthritis (RA) and periodontitis is well established. Some children with juvenile idiopathic arthritis (JIA) phenotypically resemble adults with RA, characterized by the presence of anti-cyclic citrullinated peptide (CCP) antibodies. We sought to investigate an association between CCP-positive JIA and symptoms of periodontitis and antibodies to oral microbiota. METHODS: Antibodies to oral pathogens Porphyromonas gingivalis, Prevotella intermedia, and Fusobacterium nucleatum were measured using ELISA in 71 children with CCP-positive JIA and 74 children with CCP-negative JIA. Oral health history was collected from 37 children with CCP-positive JIA and 121 children with CCP-negative JIA. T-tests, Chi-square tests, Mann-Whitney U tests, and multivariable regression were used to compare the groups. RESULTS: Compared to those with CCP-negative JIA, children with CCP-positive JIA were more likely to be female, older and non-Caucasian. Anti-P. gingivalis (p <0.003) and anti-P. intermedia (p <0.008) IgG antibody titers were higher in the CCP-positive cohort. Differences in P. gingivalis antibody titers remained significant after adjusting for age (p = 0.007). Children with CCP-positive JIA more likely reported tender/bleeding gums (43 % vs. 24 %, p < 0.02) compared to children with CCP-negative JIA. After controlling for age at collection, the odds of having tender/bleeding gums were 2.2 times higher in the CCP-positive group compared (95 % CI 0.98 - 4.83; p = 0.056). CONCLUSIONS: Children with CCP-positive JIA have higher antibody titers to P. gingivalis and more symptoms of poor oral health, supporting a possible role for periodontitis in the etiology of CCP-positive JIA.
