Ann Rheum Dis.

Is hydrocortisone replacement more effective than prednisone tapering for glucocorticoid withdrawal in rheumatoid arthritis patients with low disease activity?

Clinical Bottom Line: In patients with rheumatoid arthritis (RA) maintaining low disease activity (LDA) on a stable 5 mg/day prednisone regimen, a hydrocortisone replacement strategy did not prove superior to a gradual prednisone tapering approach for successful glucocorticoid discontinuation.

Summary: The STAR trial compared two approaches for glucocorticoid withdrawal in rheumatoid arthritis patients with stable low disease activity: hydrocortisone replacement and gradual prednisone tapering. After 12 months, both methods had similar success rates in discontinuing glucocorticoids, with no significant differences in flare rates or disease activity. No cases of acute adrenal insufficiency occurred, though some patients showed abnormal ACTH responses. The findings suggest that either strategy can be used safely for glucocorticoid withdrawal in this population.

Tools for Practice

Do gabapentinoids reduce pain in patients with fibromyalgia?

Clinical Bottom Line: Gabapentinoids, such as gabapentin and pregabalin, may provide some pain relief in fibromyalgia, but effectiveness varies, and evidence quality is low. Side effects like dizziness and weight gain are common. They can be considered as part of a personalized treatment plan but are not universally effective.

Summary: Fibromyalgia is a chronic pain condition requiring a multifaceted approach. Gabapentin and pregabalin have shown modest benefits, with pregabalin helping about one in eight patients. However, side effects are frequent, and response is inconsistent. While they may be useful for some, their role in fibromyalgia management should be individualized.

UK Health Security Agency

How should primary care practitioners diagnose and treat Helicobacter pylori infection in patients with dyspepsia?

Clinical Bottom Line: The UK Health Security Agency provides guidance for primary care on the diagnosis and treatment of Helicobacter pylori (H. pylori) infection in patients with dyspepsia. The recommended approach is a “test and treat” strategy, which involves testing for H. pylori and offering eradication therapy if the test is positive. This method aims to effectively manage dyspeptic symptoms and reduce the risk of peptic ulcer disease and gastric cancer.

Summary: Dyspepsia, characterized by upper abdominal discomfort, is commonly associated with H. pylori infection. The UK Health Security Agency’s guidance suggests that primary care practitioners implement a “test and treat” strategy for managing dyspepsia. This involves non-invasive testing for H. pylori, such as urea breath tests or stool antigen tests, and providing eradication therapy to those who test positive. Eradication typically includes a combination of antibiotics and proton pump inhibitors to eliminate the infection and promote mucosal healing. This approach not only alleviates dyspeptic symptoms but also decreases the likelihood of developing more serious gastrointestinal conditions.

CADTH

Is virtual mental health counselling as effective as in-person therapy for depression, anxiety, and PTSD?

Clinical Bottom Line: Virtual mental health counselling is as effective as in-person therapy for depression, anxiety, and PTSD. It is a first-line option for mild depression and a second-line or adjunct treatment for more severe cases, improving access to care.

Summary: A rapid review found virtual counselling comparable to in-person therapy for depression, generalized anxiety, social anxiety, panic disorder, and PTSD. It is recommended as a primary treatment for mild cases and as an adjunct for more severe conditions. For OCD, evidence is mixed. Virtual therapy expands access, especially in underserved areas.

British Columbia Guidelines

How should primary care practitioners in British Columbia manage tobacco use disorder?

Clinical Bottom Line: The BC guidelines recommend managing tobacco use disorder with pharmacotherapy (NRT, varenicline, bupropion) and counseling. The 5 A’s approach (Ask, Advise, Assess, Assist, Arrange) supports smoking cessation, with ongoing intervention needed due to high relapse rates. Cultural sensitivity is key for Indigenous patients.

Summary: Tobacco use disorder is a chronic condition requiring regular screening and a combination of medications and behavioral support. Pharmacotherapy and counseling together are most effective, with motivational interviewing enhancing patient engagement. Continuous follow-up is crucial, and care should be culturally appropriate, especially for Indigenous populations.

FSRH

Do GLP-1 Agonists Affect the Efficacy of Hormonal Contraception?

Clinical Bottom Line: Tirzepatide, a GLP-1 receptor agonist, has been found to significantly reduce the bioavailability of oral contraceptives, potentially decreasing their effectiveness. Other GLP-1 receptor agonists have not shown clinically relevant effects on oral contraceptive efficacy. Healthcare providers should consider alternative or additional contraceptive methods for patients using tirzepatide.

Summary: The Faculty of Sexual & Reproductive Healthcare (FSRH) has issued guidance regarding the interaction between GLP-1 receptor agonists and oral contraceptives. Notably, tirzepatide has been observed to reduce the bioavailability of oral contraceptives, which may compromise their contraceptive effectiveness. In contrast, other GLP-1 receptor agonists have not demonstrated a clinically significant impact on the pharmacokinetics of oral contraceptives. Given these findings, it is advisable for healthcare professionals to discuss alternative or supplementary contraceptive options with patients who are prescribed tirzepatide to ensure effective pregnancy prevention.

JAMA Pediatr.

What are the most effective pharmacologic treatments for managing acute pain in children?

Clinical Bottom Line: NSAIDs, ketamine, and mid- to high-potency opioids effectively reduce acute pain in children. NSAIDs are the preferred first-line option, as they also reduce the need for rescue medication without increasing short-term gastrointestinal risks.

Summary: A systematic review of 41 RCTs (4,935 children) found that NSAIDs, ketamine, and opioids significantly reduced pain. NSAIDs also decreased the need for rescue medication and had no increased risk of short-term GI side effects, making them the optimal first choice for pediatric acute pain.

Therapeutics Letter

Should serotonergic antidepressants be prescribed to individuals with alcohol and other substance use disorders?

Clinical Bottom Line: Serotonergic antidepressants (e.g., SSRIs) are generally ineffective for treating depression in individuals with substance use disorders (SUDs) and may worsen substance use. Treatment should prioritize reducing substance use, which often improves mental health symptoms.

Summary: The Therapeutics Initiative review highlights that depression and anxiety in SUDs are often substance-related. Stopping or reducing use typically leads to symptom improvement. Antidepressants show little benefit and may be harmful, so clinicians should focus on evidence-based addiction treatments instead.

Specialist Pharmacy Service

What are the recommended treatments for hay fever during pregnancy?

Clinical Bottom Line: First-line treatment includes allergen avoidance and saline nasal irrigation. If needed, intranasal corticosteroids or ocular mast cell stabilizers are preferred due to minimal systemic absorption. Loratadine or cetirizine are the safest oral antihistamines. Decongestants should be avoided.

Summary: Hay fever in pregnancy should be managed stepwise:

• Non-drug measures – Avoid triggers, use saline irrigation.
• Topical treatments – Intranasal steroids (e.g., fluticasone) or mast cell stabilizers.
• Oral antihistamines – Loratadine and cetirizine are safest; fexofenadine only if necessary.

Decongestants are not recommended. No extra fetal monitoring is usually needed.
