Abstract
Background: The long-COVID syndrome is characterised by a plethora of symptoms. Given its social and economic impact, many studies have stressed the urgency of proposing innovative strategies other than hospital settings. In this double-blinded, randomised, case-control trial, we investigate the effects of sulphur thermal water inhalations, rich in H2S, compared to distilled water inhalations on symptoms, inflammatory markers and nasal microbiome in long-COVID patients.
Methods: About 30 outpatients aged 18-75 with positive diagnosis for long-COVID were randomised in two groups undergoing 12 consecutive days of inhalations. The active group (STW) received sulphur thermal water inhalations whereas the placebo group received inhalations of sterile distilled non-pyrogenic water (SDW). Each participant was tested prior treatment at day 1 (T0), after the inhalations at day 14 (T1) and at 3 months follow-up (T2). At each time point, blood tests, nasal swabs for microbiome sampling, pulmonary functionality tests (PFTs) and pro-inflammatory marker measure were performed.
Results: The scores obtained in the administered tests (6MWT, Borg score and SGRQ) at T0 showed a significant variation in the STW group, at T1 and T2. Serum cytokine levels and other inflammatory biomarkers reported a statistically significant decrease. Some specific parameters of PFTs showed ameliorations in the STW group only. Changes in the STW nasopharyngeal microbiota composition were noticed, especially from T0 to T2.
Conclusions: Inhalations of sulphur thermal water exerted objective and subjective improvements on participants affected by long-COVID. Significant reduction of inflammatory markers, dyspnoea scores and quantitative and qualitative changes in the nasopharyngeal microbiome were also assessed.
期刊介绍:
Clinical Medicine is aimed at practising physicians in the UK and overseas and has relevance to all those managing or working within the healthcare sector.
Available in print and online, the journal seeks to encourage high standards of medical care by promoting good clinical practice through original research, review and comment. The journal also includes a dedicated continuing medical education (CME) section in each issue. This presents the latest advances in a chosen specialty, with self-assessment questions at the end of each topic enabling CPD accreditation to be acquired.
