    Balneotherapy as providing Whole Body Hyperthermia
    Sinan Kardeş | Department of Medical Ecology and Hydroclimatology, İstanbul Faculty of Medicine, İstanbul University
    Interesting article with attractive non-pharmacological treatment option! The results indicate that single session Whole Body Hyperthermia (core body temperature reach 38.5°C) improves symptoms of major depressive disorder. This improvement persists throughout the entire 6-week duration of follow-up.

    The whole body hyperthermia can also be reached by immersion of whole body (head-out immersion) in thermal water. This approach as a balneotherapy is widely used in many European countries and Turkey [1-3].

    The beneficial effects of balneotherapy or spa therapy in reducing depressive symptoms or stress have demonstrated in several studies conducting in fibromyalgia patients [4-6] and in healthy people [7-9].

    In balneotherapy trials
    observed clinical effects are of course mainly attributed to the balneotherapy. On the other hand, in spa therapy trials the observed clinical effects may also mainly attributed to the balneotherapy because it is main and and core intervention in spa therapy; however, the other interventions included in spa therapy regimens (i.e Turkish bath (hamam), mud-pack therapy, massage, physical therapy modalities, and aquatic/land based exercise…) and the other factors (climatotherapy, changes in environmental and social milieu…) must be taken into account as contributing factors to the clinical benefits when interpreting the results of spa therapy trials. Indeed, most spa therapy trials have aimed to evaluate efficacy of spa therapy as a whole rather than focusing each individual components of spa therapy separately as a responsible factor for improvement of symptoms [4, 10, 11].

    In short, spa therapy regimens comprising balneotherapy may considered as providing whole body hyperthermia for the management of the depressive disorders in many European countries and Turkey where these therapies are widely available and reimbursed by health health insurance systems.

    Abstract

    Importance  Limitations of current antidepressants highlight the need to identify novel treatments for major depressive disorder. A prior open trial found that a single session of whole-body hyperthermia (WBH) reduced depressive symptoms; however, the lack of a placebo control raises the possibility that the observed antidepressant effects resulted not from hyperthermia per se, but from nonspecific aspects of the intervention.

    Objective  To test whether WBH has specific antidepressant effects when compared with a sham condition and to evaluate the persistence of the antidepressant effects of a single treatment.

    Design, Setting, and Participants  A 6-week, randomized, double-blind study conducted between February 2013 and May 2015 at a university-based medical center comparing WBH with a sham condition. All research staff conducting screening and outcome procedures were blinded to randomization status. Of 338 individuals screened, 34 were randomized, 30 received a study intervention, and 29 provided at least 1 postintervention assessment and were included in a modified intent-to-treat efficacy analysis. Participants were medically healthy, aged 18 to 65 years, met criteria for major depressive disorder, were free of psychotropic medication use, and had a baseline 17-item Hamilton Depression Rating Scale score of 16 or greater.

    Interventions  A single session of active WBH vs a sham condition matched for length of WBH that mimicked all aspects of WBH except intense heat.

    Main Outcomes and Measures  Between-group differences in postintervention Hamilton Depression Rating Scale scores.

    Results  The mean (SD) age was 36.7 (15.2) years in the WBH group and 41.47 (12.54) years in the sham group. Immediately following the intervention, 10 participants (71.4%) randomized to sham treatment believed they had received WBH compared with 15 (93.8%) randomized to WBH. When compared with the sham group, the active WBH group showed significantly reduced Hamilton Depression Rating Scale scores across the 6-week postintervention study period (WBH vs sham; week 1: −6.53, 95% CI, −9.90 to −3.16, P < .001; week 2: −6.35, 95% CI, −9.95 to −2.74, P = .001; week 4: −4.50, 95% CI, −8.17 to −0.84, P = .02; and week 6: −4.27, 95% CI, −7.94 to −0.61, P = .02). These outcomes remained significant after evaluating potential moderating effects of between-group differences in baseline expectancy scores. Adverse events in both groups were generally mild.

    Conclusions and Relevance  Whole-body hyperthermia holds promise as a safe, rapid-acting, antidepressant modality with a prolonged therapeutic benefit.
