Objectives: The purpose of this study was to examine the beneficial effects of balneotherapy in patients with chronic heart failure (CHF).
Background: Some reports have shown that balneotherapy reduces systemic blood pressure in healthy volunteers. However, it is not clear whether balneotherapy improves the status of CHF. We hypothesized that hyperthermia using hot water would improve cardiac and peripheral endothelial function and clinical symptoms.
Methods: Twenty-six patients with chronic systolic heart failure classified as New York Heart Association (NYHA) functional status II or III were divided into two groups. In the balneotherapy group, patients were immersed in a hot spring at 40°C for 10min daily for two weeks; in the control group, patients took a daily shower. We measured plasma brain natriuretic peptide (BNP) and asymmetric dimethylarginine (ADMA). The left ventricular ejection fraction (LVEF) and cardiothoracic ratio (CTR) were evaluated by echocardiography and chest radiography, respectively. Brachial-ankle pulse-wave velocity (baPWV) was measured non-invasively using an automatic device.
Results: Clinical symptoms were improved after two weeks of hot spring therapy. Although heart rate and CTR did not change, clinical symptom and LVEF improved and mean blood pressure, BNP, ADMA and PWV significantly decreased.
Conclusions: Repeated immersion in a hot spring improves peripheral vascular endothelial function, thus leading to improvement of clinical activity and symptoms in patients with CHF.

Endocytoscopy (EC) is a contact-type optical endoscope that allows in vivo cellular observation during gastrointestinal endoscopy and is now commercially available not only in Japan but also in Asian, European Union, and Middle Eastern countries. EC helps conduct a highly accurate pathological prediction without biopsy. Initially, EC was reported to be effective for esophageal diseases. Subsequently, its efficacy for stomach and colorectal diseases has been reported. In this narrative review, we searched for clinical studies that investigated the efficacy of EC. EC seems to accurately diagnose gastrointestinal diseases without biopsy. Most of the studies aimed to clarify the relationship between endocytoscopic findings of gastrointestinal neoplasia and pathological diagnosis. Some studies have investigated non-epithelial lesions or diseases, such as inflammatory bowel disease or infectious diseases. However, there are few high-level pieces of evidence, such as randomized trials; thus, further studies are needed.
