Morphine and Methadone for Neonatal Abstinence Syndrome: A Systematic Review.

PURPOSE: To compare the effects of morphine and methadone on length of hospital stay (LOS) or treatment (LOT) and adverse effects in infants with neonatal abstinence syndrome (NAS). DESIGN: Systematic review. SAMPLE: PubMed, Google Scholar, Cochrane library, CINAHL, IPA, American Academy of Pediatrics, and clinicaltrials.gov were systematically searched to identify randomized controlled trials (RCTs) and observational studies. comparing morphine and methadone for NAS. OUTCOMES: LOS, LOT, adverse effects. RESULTS: One RCT, two cohort studies, and two chart reviews met inclusion criteria. Each had a low risk of bias. LOS ranged from 12.08 to 36 days with morphine and 21 to 44.23 days with methadone. LOT ranged from 7.46 to 22.9 days (morphine) and 13.9 to 38.08 days (methadone). Adverse effects were not reported. Clinical evidence comparing morphine to methadone for NAS treatment is limited and conflicting. A recommendation for one over the other cannot be made based on these outcomes.

Probiotics for the Treatment of Infantile Colic: A Systematic Review.

OBJECTIVE: To evaluate whether clinical data support the safety and efficacy of probiotics for the management of infantile colic. BACKGROUND: Probiotics have been suggested as a potential strategy for infantile colic, and the specific species that have been studied in healthy infants are considered to be safe. METHODOLOGY: A systematic review was conducted to identify randomized controlled trials (RCTs) evaluating the use of probiotic supplementation in infants with colic. RCTs with a primary end point assessing crying or fussing time were selected. A meta-analysis comparing "responders" to "nonresponders" in infants receiving probiotic versus control was conducted. The quality of trials selected was assessed. RESULTS: Five RCTs assessing 2 different strains of the probiotic Lactobacillus reuteri in mostly breastfed infants were identified. Analysis of response rates showed that infants receiving probiotics had a 2.3-fold greater chance of having a 50% or greater decrease in crying/fussing time compared to controls ( P = .01). Probiotic supplementation was not associated with any adverse events. CONCLUSION: Supplementation with the probiotic L. reuteri in breastfed infants appears to be safe and effective for the management of infantile colic. Further research is needed to determine the role of probiotics in infants who are formula-fed.

Dietary supplement interactions with antiretrovirals: a systematic review.

Many patients who take antiretroviral drugs also take alternative therapies including dietary supplements. Some drug-supplement combinations may result in clinically meaningful interactions. We aimed to investigate the evidence for dietary supplement interactions with antiretrovirals. A systematic review was conducted using multiple resources including PubMed, Natural Medicine Comprehensive Database, The Review of Natural Products, and Google Scholar. All human studies or case reports evaluating an interaction between a dietary supplement and an antiretroviral were selected for inclusion. Twenty-eight pharmacokinetic studies and case-series/case reports were selected for inclusion. Calcium carbonate, ferrous fumarate, some forms of ginkgo, some forms of garlic, some forms of milk thistle, St. John's wort, vitamin C, zinc sulfate, and multivitamins were all found to significantly decrease the levels of selected antiretrovirals and should be avoided in patients taking these antiretrovirals. Cat's claw and evening primrose oil were found to significantly increase the levels of antiretrovirals and patients should be monitored for adverse effects while taking these dietary supplements with antiretrovirals. This systematic review shows the importance of screening all human immunodeficiency virus patients for dietary supplement use to prevent treatment failure or adverse effects related to an interaction.

Characterization of Complementary and Alternative Medicine-Related Consultations in an Academic Drug Information Service.

PURPOSE: To characterize requests received through an academic drug information consultation service related to complementary and alternative medicines. METHODS: A retrospective review and descriptive analysis of drug information consultations was conducted. RESULTS: A total of 195 consultations related to complementary and alternative medicine were evaluated. All consultation requests involved questions about dietary supplements. The most common request types were related to safety and tolerability (39%), effectiveness (38%), and therapeutic use (34%). Sixty-eight percent of the requests were from pharmacists. The most frequent consultation requests from pharmacists were questions related to drug interactions (37%), therapeutic use (37%), or stability/compatibility/storage (34%). Nearly 60% of complementary and alternative medicine-related consultation requests were able to be completely addressed using available resources. Among review sources, Natural Medicines Comprehensive Database, Clinical Pharmacology, Micromedex, and Pharmacist's Letter were the most common resources used to address consultations. CONCLUSION: Utilization of a drug information service may be a viable option for health care professionals to help answer a complementary and alternative medicine-related question. Additionally, pharmacists and other health care professionals may consider acquiring resources identified to consistently answering these questions.

Regulatory alerts for dietary supplements in Canada and the United States, 2005-13.

PURPOSE: Dietary supplement regulatory alerts published by the Food and Drug Administration (FDA) and Health Canada were evaluated and characterized. METHODS: FDA MedWatch and Health Canada websites were reviewed to identify regulatory alerts regarding dietary supplements from January 1, 2005, through December 31, 2013. Alerts were analyzed to identify product characteristics that may be predictive of product quality issues and potential patient harm. RESULTS: A total of 1560 dietary supplement-related regulatory alerts were identified. Of those, 1287 (83%) were identified through Health Canada, and 273 (18%) were identified through FDA MedWatch. The country of origin of dietary supplements associated with regulatory alerts was not provided in most regulatory alerts; however, when their origin was provided, the United States was the most common. Dietary supplements intended for sexual enhancement were the subject of 33% of all regulatory alerts identified. Products purchased online were the most likely to be associated with a regulatory alert. Dietary supplements intended for sexual enhancement, weight loss, and bodybuilding or athletic performance appeared to pose the greatest risk for patient harm due to product contamination with a pharmaceutical such as a phosphodiesterase-5 inhibitor or sibutramine. CONCLUSION: Analysis of Canadian and U.S. regulatory alerts concerning dietary supplements revealed that more than 80% of the composite alerts were issued by Health Canada. The most common intended uses of supplements for which alerts were issued were sexual enhancement, weight loss, and bodybuilding or athletic performance. The most common reason for alerts was the presence of a pharmaceutical contaminant.

Dietary Supplements and Alternative Therapies for Pain Management.

The use of complementary and alternative medicines (CAM) continues to grow in North America. The most recent National Health Interview Survey found that in 2012, 33.2 percent of respondents reported usage of some form of CAM in the previous 12 months. A survey of adult patients in a U.S. dental school clinic found that 24 percent reported the use of herbal supplements. Dietary supplements and alternative therapies are often used for pain management.

Dietary supplements as disease-modifying treatments in osteoarthritis: a critical appraisal.

An array of natural substances purported to possess disease-modifying qualities for osteoarthritis are designated as "dietary supplements" and thus avoid rigorous FDA regulation. Substantial scientific evidence for the efficacy of these agents is elusive.

Comparison of Vitamin D Label Dosing Recommendations to North American National Guidelines.

Supplementation with vitamin D has become increasingly popular over the past decade, and numerous organizations have developed recommendations for the appropriate intake of vitamin D. Vitamin D supplements come in a variety of formulations and strengths and vary in their directions for use. This study was designed to compare vitamin D label dosing information with the recommendations in North American guidelines. A systematic search was conducted to identify 62 single-ingredient vitamin D products of which 1000 IU was the most common strength. Assessment of North American guidelines found recommended vitamin D dosing to range from 400 to 1000 IU daily, depending on age. Twenty-four (39%) of the products recommended a maximum dose within the range of 400 to 1000 IU daily. Thirty-eight (61%) and 19 (31%) products recommended maximum doses more than 1000 IU daily and 2000 IU daily, respectively. Labeled dosing recommendations of commercially available vitamin D supplements are largely inconsistent with North American recommendations.

Survey and Systematic Literature Review of Probiotics Stocked in Academic Medical Centers within the United States.

BACKGROUND: Probiotics have a wide variation in their effectiveness in preventing or treating conditions due to the varying beneficial effects of specific probiotic strains. In other words, there is no "generic equivalency" between different probiotic species. However, it is has been noted that many practitioners consider probiotics in generic terms and may not realize the impact of these differences between probiotics. OBJECTIVE: The aims of this study were to identify probiotics used in US academic medical centers and to determine whether those probiotics were supported by a reliable evidence base. METHODS: A phone survey of 126 inpatient pharmacies in US academic medical centers was conducted to determine which probiotics were stocked. A systematic search was conducted to identify relevant studies that were then critically evaluated to determine whether the identified probiotics are supported by a reliable evidence base. RESULTS: There was a 90.5% (114/126) response rate of academic medical centers that were contacted through the phone survey. Ten probiotic products were identified through the phone survey. The probiotic most often stocked in academic medical centers was Culturelle (27.2%) followed by Lactinex (25.4%). The systematic search identified evidence that evaluated Culturelle, Florastor, Lactinex, and VSL #3. Of those 4 probiotics, none were supported by a strong evidence base. However, the results suggested that both Culturelle and Florastor appear to be supported by more evidence compared to other probiotics. CONCLUSION: A majority of academic medical centers did not stock a probiotic that was supported by a reliable evidence base.

Factors associated with potential medication-herb/natural product interactions in a rural community.

CONTEXT: Use of both conventional medicines and herbs/natural products are increasing in the United States. Consequently, individuals are more likely to be exposed to potentially harmful interactions between these products. OBJECTIVE: To examine the use of both herbs/natural products and conventional medications in a rural community, examine the prevalence of potential interactions between herbs/natural products and conventional medications, and identify factors associated with exposure to such interactions. DESIGN: Population-based epidemiological study. SETTING: Data for this paper were collected between 1999 and 2004 as part of the Johnston County Osteoarthritis Project. PARTICIPANTS: Limited to civilian, noninstitutionalized, white or African American residents, aged 45 years or older, of Johnston County, North Carolina. Data used in this paper are from 2523 individuals who completed face-to-face interviews. MAIN OUTCOME MEASURES: Prevalence of herb/natural product use and exposure to potential interactions between these products and conventional medications. RESULTS: Nineteen percent (n=488) of participants used at least 1 herb/natural product. Among those who used both conventional medications and herbs/natural products, more than 1 in 5 (97 [21.9%]) were using a combination of products associated with a potential interaction. Odds of exposure to a potential interaction were lower among people who had health insurance and increased with the number of products used. CONCLUSIONS: Many people are exposed to potential interactions between herbs/natural products and conventional medications. Research is needed to better understand the effect such interactions may have on patient care.

Complementary and alternative medicine for the allergist-immunologist: where do I start?

Complementary and alternative medicine (CAM) therapies present a growing information management challenge for physicians because nearly 40% of their patients may be using and another 50% may be considering use of CAM as part of their healthcare regimen. The National Health Statistics Reports for 2007 described the most commonly used nonvitamin, nonmineral therapy as natural products (eg, herbals at 17.7%). More than 5% of children under the age of 18 years used CAM for allergic conditions including asthma. The amount and quality of information available and concerns about liability risk represent a challenge for most physicians. This review focuses on considerations for approaching a CAM-related consultation, incorporating legal and logistic factors affecting how such an encounter should be approached. A 10-step process is presented that addresses different components of CAM consultations and what should be documented. Access to timely, high-quality information regarding product specific efficacy and safety data, as found in the Natural Medicines Comprehensive Database, is needed to support CAM consultation efficiently. Understanding of serious adverse events associated with CAM is limited; an international need exists for improved safety surveillance and information sharing. Allergy-immunology, as a specialty with expertise in adverse drug reaction evaluation and management, has a unique opportunity to support enhanced CAM-related adverse events evaluations, reporting, and research.

Dietary supplements for osteoarthritis.

A large number of dietary supplements are promoted to patients with osteoarthritis and as many as one third of those patients have used a supplement to treat their condition. Glucosamine-containing supplements are among the most commonly used products for osteoarthritis. Although the evidence is not entirely consistent, most research suggests that glucosamine sulfate can improve symptoms of pain related to osteoarthritis, as well as slow disease progression in patients with osteoarthritis of the knee. Chondroitin sulfate also appears to reduce osteoarthritis symptoms and is often combined with glucosamine, but there is no reliable evidence that the combination is more effective than either agent alone. S-adenosylmethionine may reduce pain but high costs and product quality issues limit its use. Several other supplements are promoted for treating osteoarthritis, such as methylsulfonylmethane, Harpagophytum procumbens (devil's claw), Curcuma longa (turmeric), and Zingiber officinale (ginger), but there is insufficient reliable evidence regarding long-term safety or effectiveness.

Evaluation of the stimulant content of dietary supplements marketed as "ephedra-free".

BACKGROUND: With the removal of stimulant herb ephedra from the market, dietary supplement manufacturers are coming out with many ephedra-free products. Some of these products appear to simply replace ephedra with stimulants by another name. OBJECTIVE: To determine the stimulant content of dietary supplements marketed as ephedra-free. DESIGN: Survey of the ingredients of dietary supplements that are stated as "ephedra-free" in the label or promotional material. RESULTS: Out of 36 products marketed as ephedra-free, 32 (89%) contained a methylxanthine such as caffeine or theobromine, 21 (58%) contained the stimulant synephrine, and 20 (56%) contained both a methylxanthine and synephrine. LIMITATIONS: The results of this evaluation pertain only to products discovered through Internet and database searching. CONCLUSIONS: Most dietary supplement makers have substituted stimulants by a different name for ephedra in their "ephedra-free" products. Patients need to be advised that ephedra-free products are not necessarily stimulant free and may present a significant risk.

Inhibition of warfarin anticoagulation associated with chelation therapy.

Chelation therapy originally was administered exclusively to patients with heavy metal poisoning. Now some physicians are administering this therapy for numerous conditions, most commonly coronary heart disease. A 64-year-old man experienced impaired warfarin anticoagulation after undergoing chelation therapy His international normalized ratio (INR) fell from 2.6 the day before to 1.6 the day after therapy was administered. Whether chelation therapy decreases the effectiveness of warfarin anticoagulation is uncertain. However, because of this potential interaction, clinicians should consider increased INR monitoring in patients undergoing chelation therapy.
