AI Article Synopsis
- MOH (Medication Overuse Headache) can occur from excessive pain relief medication use, but anti-CGRP monoclonal antibodies like galcanezumab have shown promise as preventive treatments.
- A study involving 75 patients compared the effectiveness and safety of galcanezumab alone, galcanezumab with prednisone, and prednisone alone over a 3-month period.
- All treatments reduced headache frequency significantly, but the galcanezumab combined with prednisone resulted in the greatest reduction; however, prednisone had more side effects, suggesting its use should be limited to cases unresponsive to other treatments.
Article Abstract
Background: Medication overuse headache (MOH) is a condition where pain relief medications cause chronic headaches due to excessive use. Recent advancements highlight the effectiveness of preventive treatments like anti-CGRP monoclonal antibodies. Current strategies combine medication withdrawal and preventive treatments, with corticosteroids traditionally used to ease withdrawal symptoms.
Methods: This is a prospective three-arm observational cohort study comparing the effectiveness and safety of galcanezumab alone, galcanezumab plus prednisone and prednisone alone for the treatment of MOH. We enrolled 75 patients. Prednisone was administered at an initial dose of 50mg daily, and then tapered off over 28days. Duration of follow-up was 3months.
Results: All treatments proved effective (P<0.001). We found a significant reduction of mean monthly days with headache in the galcanezumab plus prednisone group (baseline: 25, IQR: 20-30; after 3months: 7, IQR: 5-10), in the galcanezumab group (baseline: 25, IQR: 20-30; after 3months: 10, IQR: 5-14) and in the Prednisone group (baseline: 25, IQR: 20-28; after 3months: median: 15 days, IQR: 8-22days). Patients treated with prednisone reported a higher incidence of side effects (P=0.002).
Conclusion: Our study indicates that both galcanezumab and prednisone decrease the frequency of headaches in patients with MOH. The combined usage of these treatments showed the highest reduction in mean monthly headache days. However, treatment with prednisone determined a significant rate of adverse events, therefore we suggest its use only in unresponsive patients. In all other patients galcanezumab appears to be a safe and effective option.

The rise in antimicrobial resistance is a vital concern, and various factors, such as the overuse of antibiotics in agriculture, have contributed to its development and spread. Livestock farmers, veterinarians, and pharmacies are key prescribers of antibiotics for disease prevention, control, and treatment of ruminant animals. A qualitative study in the Sumbawa District examined their awareness, attitudes, and practices concerning antibiotic use, residues, and resistance, underscoring their vital role in tackling this challenge.
