Testosterone Treatment in Adult Men With Age-Related Low Testosterone: A Clinical Guideline From the American College of Physicians

Description: The American College of Physicians (ACP) developed this guideline to provide clinical recommendations based on the current evidence of the benefits and harms of testosterone treatment in adult men with age-related low testosterone. This guideline is endorsed by the American Academy of Family Physicians. Methods: The ACP Clinical Guidelines Committee based these recommendations on a systematic review on the efficacy and safety of testosterone treatment in adult men with age-related low testosterone. Clinical outcomes were evaluated by using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system and included sexual function, physical function, quality of life, energy and vitality, depression, cognition, serious adverse events, major adverse cardiovascular events, and other adverse events. Target Audience and Patient Population: The target audience includes all clinicians, and the target patient population includes adult men with age-related low testosterone. Recommendation 1a: ACP suggests that clinicians discuss whether to initiate testosterone treatment in men with age-related low testosterone with sexual dysfunction who want to improve sexual function (conditional recommendation; low-certainty evidence). The discussion should include the potential benefits, harms, costs, and patient's preferences. Recommendation 1b: ACP suggests that clinicians should reevaluate symptoms within 12 months and periodically thereafter. Clinicians should discontinue testosterone treatment in men with age-related low testosterone with sexual dysfunction in whom there is no improvement in sexual function (conditional recommendation; low-certainty evidence). Recommendation 1c: ACP suggests that clinicians consider intramuscular rather than transdermal formulations when initiating testosterone treatment to improve sexual function in men with age-related low testosterone, as costs are considerably lower for the intramuscular formulation and clinical effectiveness and harms are similar. Recommendation 2: ACP suggests that clinicians not initiate testosterone treatment in men with age-related low testosterone to improve energy, vitality, physical function, or cognition (conditional recommendation; low-certainty evidence).

Overdose Prevention Through Medical Treatment of Opioid Use Disorders

Management of Suspected Opioid Overdose With Naloxone in Out-of-Hospital Settings: A Systematic Review: Annals of Internal Medicine: Vol 167, No 12

Background: Naloxone is effective for reversing opioid overdose, but optimal strategies for out-of-hospital use are uncertain. Purpose: To synthesize evidence on 1) the effects of naloxone route of administration and dosing for suspected opioid overdose in out-of-hospital settings on mortality, reversal of overdose, and harms, and 2) the need for transport to a health care facility after reversal of overdose with naloxone. Data Sources: Ovid MEDLINE (1946 through September 2017), PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL, U.S. Food and Drug Administration (FDA) materials, and reference lists. Study Selection: English-language cohort studies and randomized trials that compared different doses of naloxone, administration routes, or transport versus nontransport after reversal of overdose with naloxone. Main outcomes were mortality, reversal of overdose, recurrence of overdose, and harms. Data Extraction: Dual extraction and quality assessment of individual studies; consensus assessment of overall strength of evidence (SOE). Data Synthesis: Of 13 eligible studies, 3 randomized controlled trials and 4 cohort studies compared different administration routes. At the same dose (2 mg), 1 trial found similar efficacy between higher-concentration intranasal naloxone (2 mg/mL) and intramuscular naloxone, and 1 trial found that lower-concentration intranasal naloxone (2 mg/5 mL) was less effective than intramuscular naloxone but was associated with decreased risk for agitation (low SOE). Evidence was insufficient to evaluate other comparisons of route of administration. Six uncontrolled studies reported low rates of death and serious adverse events (0% to 1.25%) in nontransported patients after successful naloxone treatment. Limitation: There were few studies, all had methodological limitations, and none evaluated FDA-approved autoinjectors or highly concentrated intranasal formulations. Conclusion: Higher-concentration intranasal naloxone (2 mg/mL) seems to have efficacy similar to that of intramuscular naloxone for reversal of opioid overdose, with no difference in adverse events. Nontransport after reversal of overdose with naloxone seems to be associated with a low rate of serious harms, but no study evaluated risks of transport versus nontransport.

Pharmacologic Treatment of Seasonal Allergic Rhinitis: Synopsis of Guidance From the 2017 Joint Task Force on Practice Parameters

Description: The Joint Task Force on Practice Parameters, which comprises representatives of the American Academy of Allergy, Asthma and Immunology (AAAAI) and the American College of Allergy, Asthma and Immunology (ACAAI), formed a workgroup to review evidence and provide guidance to health care providers on the initial pharmacologic treatment of seasonal allergic rhinitis in patients aged 12 years or older. Methods: To update a prior systematic review, the workgroup searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from 18 July 2012 to 29 July 2016 to identify studies that addressed efficacy and adverse effects of single or combination pharmacotherapy for seasonal allergic rhinitis. In conjunction with the Joint Task Force, the workgroup reviewed the evidence and developed recommendations about initial treatment approaches by using the Grading of Recommendations Assessment, Development and Evaluation approach. Members of the AAAAI, the ACAAI, and the general public provided feedback on the draft document, which the Joint Task Force reviewed before finalizing the guideline. Recommendation 1: For initial treatment of seasonal allergic rhinitis in persons aged 12 years or older, routinely prescribe monotherapy with an intranasal corticosteroid rather than an intranasal corticosteroid in combination with an oral antihistamine. (Strong recommendation) Recommendation 2: For initial treatment of seasonal allergic rhinitis in persons aged 15 years or older, recommend an intranasal corticosteroid over a leukotriene receptor antagonist. (Strong recommendation) Recommendation 3: For treatment of moderate to severe seasonal allergic rhinitis in persons aged 12 years or older, the clinician may recommend the combination of an intranasal corticosteroid and an intranasal antihistamine for initial treatment. (Weak recommendation)

Treatment-Free Remission After Second-Line Nilotinib Treatment in Patients With Chronic Myeloid Leukemia in Chronic Phase: Results From a Single-Group, Phase 2, Open-Label Study: Annals of Internal Medicine: Vol 168, No 7

Background: Treatment-free remission (TFR)—that is, stopping tyrosine kinase inhibitor (TKI) therapy without loss of response—is an emerging treatment goal in chronic myeloid leukemia (CML). Objective: To evaluate TFR after discontinuation of second-line nilotinib therapy. Design: Single-group, phase 2, open-label study. (ClinicalTrials.gov: NCT01698905) Setting: 63 centers in 18 countries. Patients: Adults with CML in chronic phase who received TKI therapy for at least 3 years (>4 weeks with imatinib, then ≥2 years with nilotinib) and achieved MR4.5 (BCR-ABL1 ≤0.0032% on the International Scale [BCR-ABL1 IS]) while receiving nilotinib entered a 1-year consolidation phase. Those with sustained MR4.5 during consolidation were eligible to enter TFR. Interventions: Patients received nilotinib during consolidation; those who entered TFR stopped treatment. Patients with loss of major molecular response (MMR) (BCR-ABL1 IS ≤0.1%) or confirmed loss of MR4 (BCR-ABL1 IS ≤0.01%) during TFR reinitiated nilotinib treatment. Measurements: Proportion of patients without loss of MMR, confirmed loss of MR4, or treatment reinitiation within 48 weeks of stopping treatment (primary end point). Results: 163 patients who had switched from imatinib to nilotinib (for reasons including resistance, intolerance, and physician preference) enrolled in the study and entered the consolidation phase. Of these patients, 126 met the criteria for entering the TFR phase, and 73 (58% [95% CI, 49% to 67%]) and 67 (53% [CI, 44% to 62%]) maintained TFR at 48 weeks (primary end point) and 96 weeks, respectively. Of the 56 patients who reinitiated nilotinib therapy, 55 regained MMR or better and 52 regained MR4.5. None had CML progression to accelerated phase or blast crisis. Musculoskeletal pain was more frequent during the first 48 weeks after nilotinib discontinuation. Limitation: The study included a heterogeneous patient population and was not designed to compare outcomes between patients continuing and those stopping treatment. Conclusion: TFR seems achievable in patients with sustained MR4.5 after switching to nilotinib. Primary Funding Source: Novartis Pharmaceuticals Corporation.
