Sažetak
Repetitive transcranial magnetic stimulation (rTMS) is an evidence-based treatment option for major depressive disorder (MDD). However, comparisons of efficacy between the two FDA- approved protocols of rTMS modalities are lacking. The aim of this industry-independent, randomized-controlled, single-blind trial was to evaluate clinical outcome of the two FDA- approved rTMS protocols delivered by H1-coil and the figure-8-coil, in MDD patients. A total of 228 MDD patients were randomized to 20 sessions of H1-coil or 8-coil as an adjunct to standard- of-care pharmacotherapy, or standard- of-care pharmacotherapy alone. Baseline MDD symptom severity was almost the same in the three groups. Hamilton depression rating scale (HAM- D17) mean score was 17 (5.3) in H1-coil, 17 (5.4) in 8-coil, and 19 (6.1) in control group. The primary outcome was the proportion of patients achieving remission defined as HAM- D17 score ≤7 at end-of-treatment at week-4. In the intention-to-treat analysis odds ratio for remission was 1.74 (CI95% 0.79-3.83) in H1-coil compared to the 8-coil group. The difference between two rTMS protocols was not significant. Remission rate was significantly greater in both HF-rTMS groups compared to the control: 60% (CI95% 48-71%), 43% (CI95% 31-55%) and 11% (CI95% 5-20%) respectively. The response was significantly better in H1-coil, than in 8-coil group OR = 2.33 ; CI95% 1.04-5.21 (P = 0.040). The HAM-D17 was lowered by 59% in the H1-coil, 41% in the 8-coil (P = 0.048), and 17% in the control group (P < 0.001 vs H1-coil ; P = 0.003 vs 8-coil). Safety, tolerability, and the changes in quality of life were comparable. We confirmed the safety and efficacy of both FDA- approved protocols as adjunctive treatments of MDD. Better response rate and greater reduction of depression severity were observed in the H1- coil group, but without a significant difference in the remission rate between the two rTMS modalities.
