RESUMO
BACKGROUND: Lymphedema is a debilitating illness caused by insufficient lymph drainage, which can have serious physical and psychological consequences. Although water-based exercise can be useful, at present, little evidence is available regarding the outcomes of aquatic treatment for patients with lymphedema. Therefore, the aim of the present scoping review was to evaluate, from reported studies, the effects of water-based exercise on pain, limb motor function, quality of life (QoL), and limb volume among patients affected by primary and secondary upper and lower limb lymphedema. METHODS: We performed a scoping review to examine clinical studies and randomized controlled trials reported in English from 2000 to 2021 by screening the MEDLINE (PubMed) and PEDro databases. RESULTS: The search produced a total of 88 studies. Eight randomized controlled trials and one clinical study of patients with primary or secondary lymphedema of upper or lower limbs who had undergone water-based treatment were included in the present study. Most trials had focused on breast cancer-related lymphedema. The shoulder range of flexion, external rotation, and abduction have been shown to improve after performing a water-based exercise protocol. Some evidence has also demonstrated that the lymphedematous limb strength can improve. Moreover, water-based exercise seemed to improve pain perception and QoL for patients with upper or lower limb lymphedema. In contrast, in the control groups, the QoL showed a tendency to worsen over time. Although some studies had not reported beneficial effects on the lymphedematous limb volume, most of the studies examined had reported a reduction in volume, especially in the short term. No adverse events were reported in the included studies. CONCLUSIONS: The findings from the present review have shown the potential for aquatic exercise in lymphedema management. However, at the same time, the findings underline the multiple limitations resulting from the heterogeneity in the study populations and related physical activity protocols. The role of aquatic exercise in the conservative treatment of lymphedema requires further investigation in the future to define specific protocols of application.

OBJECTIVE: The present investigation aims to compare the effect of a standardized exercise protocol in thermal aquatic immersion vs dryland (DL) on patients with chronic venous disease (CVD). METHODS: Thirty-four patients with CVD (C3,Ep,As,Pr) were included in the study and randomly assigned to perform a standardized exercise protocol in a DL environment (DL group) or in a thermal water (TW group) from a natural hot spring at 33°C with a high mineral content. Leg volumetry, ankle range of motion (ROM), ultrasound-detected subcutaneous tissue and great saphenous vein (GSV) diameter were assessed. Quality of life was measured by VVSymQ and CIVIQ-20. RESULTS: After five TW sessions the average volume decrease was -432.4 ± 122.4 mL (P < .0001) in the right leg and -358.8 ± 109.3 mL (P < .0001) in the left. No significant volume change was reported at the end of the five sessions in DL. In TW, the subcutaneous tissue thickness significantly decreased (all assessment points P < .0001 right and P < .0001 left). In contrast, no significant changes were found in the DL group. The TW group showed a significant great saphenous vein caliber reduction, both in the right and left legs (6.2 ± 5.9%, P < .002; 6.1 ± 2.2%, P < .0001), whereas in the DL group no significant differences were found. After five sessions, ankle ROM significantly increased in both groups, both in dorsiflexion and in plantarflexion (right leg: TWdorsiflexionP < .0001, TWplantarflexionP < .0001; DLdorsiflexionP < .003, DLplantarflexionP < .007) (left leg: TWdorsiflexionP < .0001, TWplantarflexionP < .0001; DLdorsiflexionP < .006, DLplantarflexionP < .001). Only the TW group showed a linear correlation between volume and ankle ROM variation (right leg: R2 = 0.80, R2 = 0.75, P < .0001; left leg: R2 = 0.82, R2 = 0.81, P < .0001). The VVSymQ and CIVQ20 scores significantly improved in TW (P < .0001 and P < .0001, respectively), whereas DL showed a significant improvement only in CIVQ20 score (P < .02). CONCLUSIONS: Thermal aquatic immersion enhances the clinical benefits of a standardized exercise protocol for patients with CVD. Compared with the data available in the literature on non-TW, the present investigation shows a potential role of higher density types of water in lower limb volume control. Intense and rigorous data collection is needed to move from empirical evidence to evidence-based science in TW, a potentially very useful treatment modality for CVD.

Large vein endothelium plays important roles in clinical diseases such as chronic venous disease (CVD) and thrombosis; thus to characterize CVD vein endothelial cells (VEC) has a strategic role in identifying specific therapeutic targets. On these bases we evaluated the effect of the natural anti-inflammatory compounds α-Lipoic acid and Ginkgoselect phytosome on cytokines/chemokines released by CVD patient-derived VEC. For this purpose, we characterized the levels of a panel of cytokines/chemokines (n = 31) in CVD patients' plasma compared to healthy controls and their release by VEC purified from the same patients, in unstimulated and TNF-α stimulated conditions. Among the cytokines/chemokines released by VEC, which recapitulated the systemic profile (IL-8, TNF-α, GM-CSF, INF- α2, G-CSF, MIP-1ß, VEGF, EGF, Eotaxin, MCP-1, CXCL10, PDGF, and RANTES), we identified those targeted by ex vivo treatment with α-Lipoic acid and/or Ginkgoselect phytosome (GM-CSF, G-CSF, CXCL10, PDGF, and RANTES). Finally, by investigating the intracellular pathways involved in promoting the VEC release of cytokines/chemokines, which are targeted by natural anti-inflammatory compounds, we documented that αLipoic acid significantly counteracted TNF-α-induced NF-κB and p38/MAPK activation while the effects of Ginkgo biloba appeared to be predominantly mediated by Akt. Our data provide new insights into the molecular mechanisms of CVD pathogenesis, highlighting new potential therapeutic targets.
