Pressure and stiffness of a new air-inflated compression wrap

OBJECTIVE

To report pressure and stiffness, in healthy volunteers, of a new compression device with an air bladder inflated by a pump to regulate pressure.

METHODS

The device was applied to 60 legs of 30 volunteers and set to exert different pressures of 20-50 mmHg. The exerted pressure was measured in supine and standing positions and during simple physical exercises; static stiffness index, dynamic stiffness index, and walking pressure amplitudes were calculated.

RESULTS

The exerted pressure showed a good correlation with the expected pressure at each pressure range. The stiffness indices were >10 mmHg in the range of inelastic materials. The device was considered very easy to apply and use by the testing researchers.

CONCLUSIONS

The device stiffness is in the same range as the inelastic bandages. Consequently, similar hemodynamic effectiveness could be expected but must be proved. Unlike inelastic bandages, this device was easy to apply and use.

Black holes in compression therapy: A quest for data

OBJECTIVE

Although compression therapy (CT) is considered a crucial conservative treatment in chronic venous disease, strong evidence is missing for many clinical indications. This literature review aims to point out what strong evidence we have for CT and all the clinical scenarios where strong evidence still needs to be included.

METHODS

The research was conducted on MEDLINE with PubMed, Scopus and Web of Science. The time range was set between January 1980 and October 2022. Only articles in English were included.

RESULTS

The main problem with CT is the low scientific quality of many studies on compression. Consequently, we have robust data on the effectiveness of CT only for advanced venous insufficiency (C3-C6), deep vein thrombosis and lymphedema. We have data on the efficacy of compression for venous symptoms control and in sports recovery, but the low quality of studies cannot result in a strong recommendation. For compression in postvenous procedures, superficial venous thrombosis, thromboprophylaxis, post-thrombotic syndrome prevention and treatment, and sports performance, we have either no data or very debated data not allowing any recommendation.

CONCLUSIONS

We need high-level scientific studies to assess if CT can be effective or definitely ineffective in the clinical indications where we still have a paucity of or contrasting data.

Effects of lower limb muscle strengthening on interface pressure in older adults undergoing inelastic compression: Randomized controlled clinical trial

OBJECTIVE

To analyze the effects of lower limb muscle strengthening on interface pressure (IP), static stiffness index (SSI), dynamic stiffness index (DSI), and walking pressure amplitude (WPA) in older adults undergoing inelastic compression therapy.

METHOD

Forty-three healthy older adults of both sexes (Age: 66.2 ± 4.4 years) met the eligibility criteria and completed all stages of the study (Resistance Training - RT: N = 20; Control - CONT: N = 23). Body composition, strength and functional mobility of lower limbs, IP, SSI, DSI, and WPA were evaluated before and after intervention.

RESULTS

The two-way ANOVA with repeated measures demonstrated a significant time-group interaction effect on muscular strength for 1-RM [F (1, 41) = 21.091; p ≤ 0.001], IP in the orthostatic position [F (1, 41) = 5.124; p ≤ 0.05], minimum WPA [F (1, 41) = 10.999; p ≤ 0.05], maximum WPA [F (1, 41) = 8.315; p ≤ 0.05], DSI minimum (F (1, 41) = 4.608; p ≤ 0.05), DSI maximum (F (1, 41) = 8.926; p ≤ 0.05), and on the delta DSI (F (1, 41) = 7.891; p ≤ 0.05).

CONCLUSIONS

In RT group, the increase in lower limb muscle strength was accompanied by an increase in IP in foot dorsiflexion and plantar flexion maneuvers, both in the standing position (DSI) and during gait (WPA).

Rationale and current evidence of aquatic exercise therapy in venous disease: A narrative review

Chronic venous disorders (CVD) of the lower limbs can be treated with different strategies. Typically, conservative management is based on compression therapy, anticoagulants and venoactive drugs. Endovenous treatments remain the gold standard to treat saphenous insufficiency, with sclerotherapy and surgery maintaining a role in selected cases. In addition, several 'unconventional' approaches have been proposed to prevent CVD progression and complications, minimize symptoms and improve the quality of life and postoperative outcomes. Among these, balneotherapy and aquatic exercises are proving as valid and effective supporting treatments, as mentioned in a growing number of scientific publications. Moreover, aquatic protocols have been studied for both venous and lymphatic insufficiency. For these reasons, they were mentioned in the last CVD guidelines provided by the European Society for Vascular Surgery. The aim of this narrative review is to overview and summarize current literature evidences on the role and effectiveness of aquatic rehabilitative protocols in CVD, reviewing old and current literature. Furthermore, the physical basis of the effects of water immersion on lower limb venous and tissues modifications are also described.

No More Venous Ulcers-What More Can We Do?

Venous leg ulcers (VLUs) are the most severe complication caused by the progression of chronic venous insufficiency. They account for approximately 70-90% of all chronic leg ulcers (CLUs). A total of 1% of the Western population will suffer at some time in their lives from a VLU. Furthermore, most CLUs are VLUs, defined as chronic leg wounds that show no tendency to heal after three months of appropriate treatment or are still not fully healed at 12 months. The essential feature of VLUs is their recurrence. VLUs also significantly impact quality of life and could cause social isolation and depression. They also have a significant avoidable economic burden. It is estimated that the treatment of venous ulceration accounts for around 3% of the total expenditure on healthcare. A VLU-free world is a highly desirable aim but could be challenging to achieve with the current knowledge of the pathophysiology and diagnostic and therapeutical protocols. To decrease the incidence of VLUs, the long-term goal must be to identify high-risk patients at an early stage of chronic venous disease and initiate appropriate preventive measures. This review discusses the epidemiology, socioeconomic burden, pathophysiology, diagnosis, modes of conservative and invasive treatment, and prevention of VLUs.

Sclerotherapy of lower limb veins: Indications, contraindications and treatment strategies to prevent complications - A consensus document of the International Union of Phlebology-2023

BACKGROUND

Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events.

OBJECTIVES

To categorise contraindications to sclerotherapy based on the available scientific evidence.

METHODS

An international, multi-disciplinary panel of phlebologists reviewed the available scientific evidence and developed consensus where evidence was lacking or limited.

RESULTS

Absolute Contraindications to sclerotherapy where the risk of harm would outweigh any benefits include known hypersensitivity to sclerosing agents; acute venous thromboembolism (VTE); severe neurological or cardiac adverse events complicating a previous sclerotherapy treatment; severe acute systemic illness or infection; and critical limb ischaemia. Relative Contraindications to sclerotherapy where the potential benefits of the proposed treatment would outweigh the risk of harm or the risks may be mitigated by other measures include pregnancy, postpartum and breastfeeding; hypercoagulable states with risk of VTE; risk of neurological adverse events; risk of cardiac adverse events and poorly controlled chronic systemic illness. Conditions and circumstances where Warnings and Precautions should be considered before proceeding with sclerotherapy include risk of cutaneous necrosis or cosmetic complications such as pigmentation and telangiectatic matting; intake of medications such as the oral contraceptive and other exogenous oestrogens, disulfiram and minocycline; and psychosocial factors and psychiatric comorbidities that may increase the risk of adverse events or compromise optimal treatment outcomes.

CONCLUSIONS

Sclerotherapy can achieve safe clinical outcomes provided that (1) patient-related risk factors and in particular all material risks are (1a) adequately identified and the risk benefit ratio is clearly and openly discussed with treatment candidates within a reasonable timeframe prior to the actual procedure; (1b) when an individual is not a suitable candidate for the proposed intervention, conservative treatment options including the option of 'no intervention as a treatment option' are discussed; (1c) complex cases are referred for treatment in controlled and standardised settings and by practitioners with more expertise in the field; (1d) only suitable individuals with no absolute contraindications or those with relative contraindications where the benefits outweigh the risks are offered intervention; (1e) if proceeding with intervention, appropriate prophylactic measures and other risk-mitigating strategies are adopted and appropriate follow-up is organised; and (2) procedure-related risk factors are minimised by ensuring the treating physicians (2a) have adequate training in general phlebology with additional training in duplex ultrasound, procedural phlebology and in particular sclerotherapy; (2b) maintain their knowledge and competency over time and (2c) review and optimise their treatment strategies and techniques on a regular basis to keep up with the ongoing progress in medical technology and contemporary scientific evidence.

Effectiveness of Blue light photobiomodulation therapy in the treatment of chronic wounds. Results of the Blue Light for Ulcer Reduction (B.L.U.R.) Study

BACKGROUND

Lower limb ulcers not responding to standard treatments after 8 weeks are defined as chronic wounds, and they are a significant medical problem. Blue light (410-430 nm) proved to be effective in treating wounds, but there is a lack of data on chronic wounds in clinical practice. The study's purpose was to determine if Blue Light photobiomodulation with EmoLED medical device in addition to Standard of Care is more effective compared to Standard of care alone in promoting re-epithelialization of chronicwounds of lower limbs in 10 weeks.

METHODS

90 patients affected by multiple or large area ulcers were enrolled. To minimize all variabilities, each patient has been used as control of himself. Primary endpoint was the comparison of the re-epithelialization rate expressed as a percentage of the difference between the initial and final area. Secondary endpoints were: treatment safety, pain reduction, wound area reduction trend over time, healing rate.

RESULTS

At week 10, the wounds treated with EmoLED in addition to Standard Care showed a smaller residual wound area compared to the wounds treated with Standard of Care alone: 42.1% vs 63.4% (p=0.029). The difference is particularly evident in venous leg ulcers, 33.3% vs 60.1% (p=0.007). 17 treated wounds and 12 controls showed complete healing at week 10. Patients showed a significant reduction in pain (p = 2*10-7).

CONCLUSIONS

Blue Light treatment in addition to Standard of Care accelerates consistently the re-epithelialization rate of chronic wounds, especially venous leg ulcers and increases the chances of total wound healing in 10 weeks.

The ICC Compression Questionnaire: A Comprehensive Tool to Evaluate Compression Materials or Devices Applied in Subjects with Lymphedema or Chronic Venous Disease

Background:

Compression therapy is an important part of the treatment of patients with lymphedema or chronic venous disease. However, there is no validated questionnaire evaluating the effect of compression and its acceptance by the patient. Therefore, the aims of this study were to construct a questionnaire evaluating the effect of compression and its acceptance by the patient, that is, the Dutch ICC Compression Questionnaire (ICC-CQ), to investigate its reliability and validity, and to translate it into English.

Methods and Results:

Eleven experts in applying compression and 51 Dutch patients with experience of using compression were involved in the construction process. One part of the ICC-CQ has to be completed by the patient and evaluates seven domains. The other part has to be completed by the health care provider and comprises three domains. Reliability and validity of the final version was investigated in a new group of 79 Dutch-speaking patients with lymphedema or chronic venous disease, wearing compression garments (N = 52) or bandages (N = 27). Except for one domain, the Intraclass Correlation Coefficients for test–rest/interrater reliability ranged from 0.55 to 0.93. Cronbach's alpha for internal consistency ranged from 0.71 to 0.97. Eighty-nine percent of the patients fully understood the questionnaire indicating good face validity, and 87% found it complete indicating good content validity. Construct validity was considered good since 10 out of 11 hypotheses were accepted.

Conclusion:

The ICC-CQ is the first reliable and valid questionnaire evaluating different kinds of compression and the experience by patients with lymphedema or chronic venous disease.

The effects of water immersion and walking on leg volume, ankle circumference and epifascial thickness in healthy subjects with occupational edema

BACKGROUND

Balneotherapy has been considered beneficial in patients with chronic venous disease due to patient-reported positive outcomes on improvement of symptoms and quality of life.Study aim: Assessing the effects of prolonged water immersion (WI) on leg edema and epifascial thickness and to compare these data with those achieved after continuous walking on ground.

MATERIAL AND METHODS

On three consecutive days, 14 otherwise healthy volunteers (9 females, 5 males, mean age 53 ± 10 years) affected by occupational edema (OE), defined as the edema developing during the time period of the working day and disappearing overnight, stayed standing immobile in a swimming pool for 30 minutes (30'), continuously walking again for 30' in the same pool and walking on ground for 30' without interruptions in a randomized sequence. Leg volume, ankle circumference and epifascial thickness of both legs were assessed each day before and after each intervention.

RESULTS

Leg volume showed a median reduction by 4.20% (IQR 5-3.6) (p = 0.0002) after 30' of immobile standing immersion and by 6.50% (IQR 7.30-5.61) (P < 0.0001) when the patients walked in the pool. Ankle circumference showed a median reduction by 2.89% (IQR 4.23-2.03) (p = 0.02) with the subjects staying standing still in water and by 5.98% (IQR 7.47-4.14) (p = 0.0002) after 30' walking in the pool. Epifascial thickness showed a median reduction by 24.35% (IQR 35.26-22.5) (P < 0.0001) when the volunteers remained standing still and by 32.66% (IQR 36.91-28-84) (P < 0.0001), when walking in water. Leg volumetry showed a median reduction by 0.20% (IQR-0.44-0.29) (p = 0.375) after walking on ground for 30'. Ankle circumference and epifascial thickness did not show any difference walking on ground compared to baseline situation.

CONCLUSIONS

This study showed that 30' of WI, especially when associated with walking, reduced leg volume in otherwise heathy subjects with OE and that walking outside the water did not.

Compression Stocking With 100% Donning and Doffing Success: An Open Label Randomised Controlled Trial

OBJECTIVE

The aim of this study was to test whether an investigational two layer stocking exerting 27-29 mmHg pressure at the medial supramalleolar level, but without compression in the foot and heel, is easier to put on and take off than a standard stocking of the same compression class (23-32 mmHg), and also to assess the prevention of diurnal oedema with both types of stocking.

METHODS

This was an open label randomised controlled trial, which included 47 patients. All participants were at least 65 years of age and suffered from chronic venous disease class C3 - C6 in one leg. The primary end point was donning success; secondary endpoints were doffing success, prevention of diurnal oedema over one day, and the comfort of wearing the stocking. Patients were randomly allocated to one of two groups. Both types of compression stocking were compared in each group for ease of donning and doffing in the manner of a crossover study. Subsequently, patients wore the stocking type assigned to their group for a whole day to evaluate comfort and the effect on diurnal leg volume.

RESULTS

All participants were able to don the investigational stocking unaided, compared with 75% for the standard stocking (p < .001). Unaided removal success was 100% with the investigational stocking vs. 66% for the standard stocking (p < .001). There was no significant difference in leg volume reduction between the study groups after a day of wear. The investigational stocking was also rated as being more comfortable than the standard stocking (p < .001).

CONCLUSION

The investigational stocking, which has no compression in the foot or heel area, is significantly easier to don and doff, with no inferiority in oedema prevention, compared with a standard stocking of the same compression class.

Bioimpedance spectroscopy and volumetry in the immediate/short-term monitoring of intensive complex decongestive treatment of lymphedema

AIMS

To assess (a) immediate/short-term outcomes of intensive complex decongestive treatment of lower limb lymphedema, by means of bioimpedance spectroscopy and tape measurement-based volumetry, and (b) correlation between these two methods.

PATIENTS AND METHODS

Cohort study on patients affected by unilateral primary or secondary lymphedema, stage II or III. Patients underwent complex decongestive treatment (manual and electro-sound lymphatic drainage, compression bandage, exercises, low-carb nutrition, and dietary supplements) for six days. Before (D0), three and six days after complex decongestive treatment (D3 and D6), volumetry and bioimpedance spectroscopy data of the total limb and lower leg were collected. Statistical analysis was applied to pre-post treatment outcomes and to the volumetry/bioimpedance spectroscopy correlation.

RESULTS

Forty-one patients (15 males and 26 females, mean age: 50.7 years) were included. A progressive improvement of volumetry and bioimpedance spectroscopy figures was recorded. Total limb and leg volumetry (mean value in cc) was, respectively, 11,072.9 and 3150.8 at D0, 10,493 (-5.2%, p = 0.001) and 2980.2 (-5.4%, p < 0.001) at D6. Total limb lymphatic index at D0 and D6 was 18.9 and 14.8 (-21.5%, p < 0.001). Total limb resistance at D0, D3, and D6 was 200.4, 225.7, and 237.5 (+18.5%, p < 0.001), respectively; leg resistance at D0 and D6 was 117.5 and 150 (+27.7%, p < 0.001), respectively. Total limb reactance at D0, D3, and D6 was 12.2, 15, and 16.6 (+35.5%, p < 0.001), respectively. Leg reactance at D0 and D6 was 7.7 and 11.5 (+ 49.6%, p < 0001), respectively. Correlation volumetry/bioimpedance spectroscopy data were (a) total limb volumetry/resistance rho = -0.449, p < 0.01; volumetry/reactance rho=-0.466, p < 0.01; volumetry/lymphatic index rho = 0.581, p < 0.01; (b) leg volumetry/resistance rho=-0.579, p < 0.01; volumetry/reactance rho=-0.469, p < 0.01; volumetry/lymphatic index rho = 0.466, p < 0.05.

CONCLUSIONS

Complex decongestive treatment on lymphedematous limbs was effective at short term; both volumetry and bioimpedance spectroscopy showed a statistically significant improvement. Resistance and reactance increase, with lymphatic index decrease, correlated with volumetry decrease. Bioimpedance spectroscopy proved to help to assess fluid decrease and the tissue-related parameters variations.

Risks and contraindications of medical compression treatment - A critical reappraisal. An international consensus statement

Objectives

Medical compression therapy is used for non-invasive treatment of venous and lymphatic diseases. Medical compression therapy-associated adverse events and contraindications have been reported, although some contraindications are theoretically based. This consensus statement provides recommendations on medical compression therapy risks and contraindications.

Methods

A systematic literature search of medical compression therapy publications reporting adverse events up until November 2017 was performed. A consensus panel comprising 15 international experts critically reviewed the publications and formulated the recommendations.

Results

Sixty-two publications reporting medical compression therapy adverse events were identified. The consensus panel issued 21 recommendations on medical compression therapy contraindications and adverse event risk mitigation, in addition to reviewing medical compression therapy use in borderline indications. The most frequently reported non-severe medical compression therapy-associated adverse events included skin irritation, discomfort and pain. Very rare but severe adverse events, including soft tissue and nerve injury, were also identified.

Conclusion

This consensus statement summarises published medical compression therapy-associated adverse events and contraindications, and provides guidance on medical compression therapy. Severe medical compression therapy-associated adverse events are very rarely encountered if compression is used correctly and contraindications are considered.

Photodynamic therapy in infected venous and mixed leg ulcers: a pilot experience

OBJECTIVE

To assess the tolerability and efficacy of photodynamic therapy (PDT) with RLP068, a novel phthalocyanine-derived photosensitiser, in controlling the bacterial load in different leg ulcers, due to vascular pathophysiology.

METHOD

An observational study of patients with infected leg ulcers of different pathophysiology, admitted to the hospital for a skin grafting procedure, were included. All patients underwent two sessions of PDT at time zero and after 72 hours. A semi-quantitative swab was taken before and 30 minutes after both sessions of PTD. During the time interval between the two treatments the ulcer was covered with foam dressing and compression therapy was applied to all patients. No systemic or topical antibiotics were administered. Statistical analysis of results was performed.

RESULTS

A total of 36 patients (13 males, 23 females; aged 72.4±8.6 years, range: 55-85 years) were recruited; two had ulcers on both legs. PDT was shown to be effective in reducing bacterial load after the first treatment. Before the second PDT treatment (72 hours after first PDT treatment), a slight increase of the bacterial load was observed in all ulcers. However, after the second PDT session, bacterial swab results were negative in all but two ulcers. The procedure was well tolerated in all but four patients, who reported a very severe pain at baseline, which increased during treatment.

CONCLUSION

In this study, PDT was effective in reducing bacterial load in patients with infected vascular leg ulcers, and allowed successful skin grafting to take place in all patients. The treatment was generally well tolerated. Studies with a greater number of patients and a control group are planned to confirm these results.

Global guidelines trends and controversies in lower limb venous and lymphatic disease: Narrative literature revision and experts' opinions following the vWINter international meeting in Phlebology, Lymphology & Aesthetics, 23-25 January 2019

Guidelines are fundamental in addressing everyday clinical indications and in reporting the current evidence-based data of related scientific investigations. At the same time, a spatial and temporal issue can limit their value. Indeed, variability in the recommendations can be found both among the same nation different scientific societies and among different nations/continents. On the other side, Garcia already published in 2014 data showing how, after three years in average, one out of five recommendations gets outdated (Martinez Garcia LM, Sanabria AJ, Garcia Alvarez E, et al. The validity of recommendations from clinical guidelines: a survival analysis. CMAJ 2014;186(16):1211–1219). The present document reports a narrative literature revision on the major international recommendations in lower limb venous and lymphatic disease management, focusing on the different countries’ guidelines, trends and controversies from all the continents, while identifying new evidence-based data potentially influencing future guidelines. World renowned experts’ opinions are also provided. The document has been written following the recorded round tables scientific discussions held at the vWINter international meeting (22–26 January 2019; Cortina d’Ampezzo, Italy) and the pre- and post-meeting literature search performed by the leading experts.

Case-control evaluation of the impact of below 20 mmHg elastic compression stockings on lower limb volume serial variations in standardized flights

Background

Graduated compression stocking (GCS) use during flights demonstrated to positively impact leg oedema. Nevertheless, these data were collected in a single flight, mainly at the ankle, and using greater than 20 mmHg GCS. This investigation reports data from 16 flights in which the same passenger’s leg circumferences variation were assessed wearing non-graduated ankle-sock or a below-knee 15–20 mmHg GCS.

Methods

The limb was divided by the circumferences in eight sectors, every 4 cm, labelled from 1 to 8, starting from the ankle up. The assessment was done at the take-off and after a 4-h flight time, for a total of 16 flights. The subject used non-graduated ankle socks (elastic band at 4 cm from B-point) during the outgoing flight and below-knee GCS (15–20 mmHg) during the return flight. Interface pressure was assessed at the ankle point of minimum girth (B) and ascending proximally every 4 cm (B+cm) for the GCS, and at B and at the elastic band level (B + 4 cm) for the sock.

Results

GCS interface pressure was 13.3 ± 2.5 mmHg in B and 18.1 ± 2.4 mmHg in B + 4 cm. The sock interface pressure was 3.1 ± 0.7 mmHg in B and 8.1 ± 0.9 mmHg at the band level (B + 4 cm). Socks led to a significant total volume increase (117.3 ± 25.8 mL; 5.2% ±1.1%; P < 0.0001). GCS led to a non-significant total volume decrease (–3.1 ± 14.4 mL; –0.1 ± 0.6%; P = 0.3964) and did not allow for volume increase. The different sectors showed a heterogeneous volume variation, not following a precisely graduated or progressive compression profile.

Conclusions

Leg oedema following a 4-h flight is controlled by <20 mmHg GCS. Leg fluids, with and without GCS, are mobilized in a non-graduated profile from the ankle to the knee after prolonged sitting on a plane.

Adjustable compression wrap devices are cheaper and more effective than inelastic bandages for venous leg ulcer healing. A Multicentric Italian Randomized Clinical Experience

Introduction

Compression therapy by inelastic bandages is highly effective in achieving venous leg ulcer healing. Inelastic bandages may be expensive as they need to be changed and discarded at every dressing change. In addition, correct application is difficult in the clinical practice, even by expert healthcare personnel. The aim of our work was to assess whether adjustable compression wraps are more cost effective and more effective than inelastic bandage to achieve venous leg ulcer healing.

Methods

Sixty-six venous leg ulcer patients were randomized to be treated by adjustable compression wrap (CircAid® JuxtaCure®) ( n = 33) and inelastic bandage (Coban 2 Layer®) ( n = 33). Study duration was 12 weeks. During weekly visits, the ulcers were cleansed and dressed with the same products, and the only variable was the compression device. Ulcer size, ulcer pain, patient’s perception of compression systems, and compression pressure were assessed during the visits, and the material cost was evaluated at the 12th week.

Results

Adjustable compression wraps were significantly cheaper than bandages (p < 0.0001) and were also more effective (not significantly) in achieving ulcer healing. To heal one ulcer patient, €228 had to be spent when applying an adjustable compression wrap and €381 if inelastic bandages were used. About 26/33 (78.8%) patients in the adjustable compression wrap group were healed after 12 weeks versus 23/33 (69.7%) in the inelastic bandage group (n.s.). Ulcer pain was reduced by both compression devices. Patient perception of compression pressure was similar with both compression devices. Compression pressure was similar at application but better maintained by adjustable compression wrap over time.

Conclusions

Adjustable compression wraps are significantly cheaper and more effective (not significantly) in achieving venous leg ulcer healing. Self-applicable, adjustable compression wraps are therefore a powerful, cost-effective alternative to inelastic bandages in treating venous leg ulcer.

Lymphedema and nutrition: A review

Nutrition is considered a basic component in the management of any vascular disease. Lymphedema is characterised by an increase of interstitial fluid due to a lymphatic system morphological and/or functional alteration. Therapeutic management of lymphedema includes a multi-faceted approach based on compression and physiotherapy mainly. Weight control and antiinflammatory and anti-edema diet are two additional necessary components of the holistic therapy in presence of primary or secondary limb lymphedema. This narrative review provides the available information derived from the scientific literature on nutrition in lymphedema, which anyway lacks robust evidence. Additional information and speculations are provided on the role of food, diet, nutraceuticals and fasting on the basic processes at the root of the chronic progressive degeneration of tissue lymph stasis, i.e. weight excess, inflammation, edema, fibroadiposis. More targeted and randomized studies are needed in order to assess and standardise the obvious, so far neglected, role of nutrition in lymphedema patients.

Compression therapy in lymphedema: Between past and recent scientific data

Aim

To extrapolate and discuss the scientific data on compression in lymphedema treatment, so to review old and innovative concepts about pressure, stiffness and other interplaying factors related to its efficacy and comfort.

Material and methods

Narrative review based on search in Medline/Google Scholar through key-words related to compression in lymphedema.

Results

Currently available literature lacks relevant details about data on protocol, devices, techniques, interface pressure, stiffness, as well as biases are represented by the different descriptions to present the outcomes. More recent evidence from adjustable wrap devices and elastic garments question the need for high pressure (especially for the upper limb) and stiffness in lymphedema treatment.

Conclusions

At present time a very strong compression pressure exerted by material with high stiffness seem to be questionable in lymphedema treatment. A low pressure provides the best outcomes in arm lymphedema, while a pressure in the range of 40–60 mm Hg seems to provide higher efficacy in lower limb lymphedema, provided it is maintained overtime. A high stiffness seems to be unnecessary to treat chronic edema. Future clinical trials, including proper description of treatment methodology and adequate investigating instrumental tools, are awaited to possibly corroborate the conclusive outcomes of our review.

The Static Stiffness Index: an important parameter to characterise compression therapy in vivo

The compression pressure, which corresponds to the dosage of compression therapy, has been widely neglected up to now, not only concerning scientific literature, but also in clinical practice. It is evident that compression pressures in the upright position and during walking are clinically more relevant than just the resting pressure. The Static Stiffness Index (SSI), which is the difference between standing and resting pressure, is a valuable parameter characterising the efficacy of a specific compression product to narrow/occlude the venous lumen. This is a prerequisite for reducing venous reflux and exerting a massaging effect necessary to improve the venous pumping function during movement. This article provides an overview of the recent literature on the SSI, which supports the recommendations of the International Compression Club. In addition, it aims to provide an insight on the importance of the SSI in daily practice, as an educational tool as well as in defining the properties of applied compression therapy in clinical research.

Management of Patients With Venous Leg Ulcers: Challenges and Current Best Practice

Introduction It is well documented that the prevalence of venous leg ulcers (VLUs) is increasing, coinciding with an ageing population. Accurate global prevalence of VLUs is difficult to estimate due to the range of methodologies used in studies and accuracy of reporting. (1) Venous ulceration is the most common type of leg ulceration and a significant clinical problem, affecting approximately 1% of the population and 3% of people over 80 years of age (2) in westernised countries. Moreover, the global prevalence of VLUs is predicted to escalate dramatically, as people are living longer, often with multiple comorbidities. Recent figures on the prevalence of VLUs are based on a small number of studies, conducted in Western countries, and the evidence is weak. However, it is estimated that 93% of VLUs will heal in 12 months, and 7% remain unhealed after five years. (3) Furthermore, the recurrence rate within 3 months after wound closure is as high as 70%. (4) (-6) Thus, cost-effective adjunct evidence-based treatment strategies and services are needed to help prevent these ulcers, facilitate healing when they occur and prevent recurrence. The impact of a VLU represents social, personal, financial and psychological costs on the individual and further economic drain on the health-care system. This brings the challenge of providing a standardised leg ulcer service which delivers evidence-based treatment for the patient and their ulcer. It is recognised there are variations in practice and barriers preventing the implementation of best practice. There are patients not receiving appropriate and timely treatment in the initial development of VLUs, effective management of their VLU and preventing recurrence once the VLU has healed. Health-care professionals (HCPs) and organisations must have confidence in the development process of clinical practice guidelines and have ownership of these guidelines to ensure those of the highest quality guide their practice. These systematic judgments can assist in policy development, and decision making, improve communication, reduce errors and improve patient outcomes. There is an abundance of studies and guidelines that are available and regularly updated, however, there is still variation in the quality of the services offered to patients with a VLU. There are also variations in the evidence and some recommendations contradict each other, which can cause confusion and be a barrier to implementation. (7) The difference in health-care organisational structures, management support and the responsibility of VLU management can vary in different countries, often causing confusion and a barrier to seeking treatment. These factors further complicate the guideline implementation process, which is generally known to be a challenge with many diseases. (8).

Compression with 23 mmHg or 35 mmHg stockings after saphenous catheter foam sclerotherapy and phlebectomy of varicose veins: A randomized controlled study

Objectives

To compare two different medical compression stockings after varicose vein treatment.

Patients and methods

A randomized single-blind controlled study on two compression regimes after saphenous catheter foam sclerotherapy + phlebectomy was performed. After pads and 5 mmHg contention sock, 23 mmHg (group A, Struva 23®) or 35 mmHg (group B, Struva 35®) medical compression stocking was applied 24 h/day for seven days; subsequently 21–23 mmHg medical compression stocking in daytime. Symptoms, compliance, skin findings, and bioimpedance spectroscopy parameters were assessed.

Results

A total of 94 patients (48 and 49 limbs in groups A and B, respectively) were enrolled. Three (T3) and seven (T7) days post-operatively, most symptoms were significantly milder in group B, especially pain and heaviness at T7 and at day 40 (T40). Ambulation, medical compression stocking stability/tolerability and skin healing were significantly better in group B, with p = 0.046, 0.021/0.060, and 0.010, respectively, at T7. Bioimpedance parameters increased at T7 and decreased at T40 in both groups; leg reactance and limb L-Dex improved in group B at T7 and T40, respectively (p = 0.039 and 0.012).

Conclusions

Compression with 23 and 35 mmHg medical compression stocking after catheter foam sclerotherapy + phlebectomy was effective and well tolerated at immediate/short term. Compression with 35 mmHg medical compression stocking provided less adverse post-operative symptoms and better tissue healing. Bioimpedance results confirmed a slightly better edema improvement with 35 mmHg medical compression stocking.

Indications for medical compression stockings in venous and lymphatic disorders: An evidence-based consensus statement

Objective Medical compression stockings are a standard, non-invasive treatment option for all venous and lymphatic diseases. The aim of this consensus document is to provide up-to-date recommendations and evidence grading on the indications for treatment, based on evidence accumulated during the past decade, under the auspices of the International Compression Club. Methods A systematic literature review was conducted and, using PRISMA guidelines, 51 relevant publications were selected for an evidence-based analysis of an initial 2407 unrefined results. Key search terms included: 'acute', CEAP', 'chronic', 'compression stockings', 'compression therapy', 'lymph', 'lymphatic disease', 'vein' and 'venous disease'. Evidence extracted from the publications was graded initially by the panel members individually and then refined at the consensus meeting. Results Based on the current evidence, 25 recommendations for chronic and acute venous disorders were made. Of these, 24 recommendations were graded as: Grade 1A (n = 4), 1B (n = 13), 1C (n = 2), 2B (n = 4) and 2C (n = 1). The panel members found moderately robust evidence for medical compression stockings in patients with venous symptoms and prevention and treatment of venous oedema. Robust evidence was found for prevention and treatment of venous leg ulcers. Recommendations for stocking-use after great saphenous vein interventions were limited to the first post-interventional week. No randomised clinical trials are available that document a prophylactic effect of medical compression stockings on the progression of chronic venous disease (CVD). In acute deep vein thrombosis, immediate compression is recommended to reduce pain and swelling. Despite conflicting results from a recent study to prevent post-thrombotic syndrome, medical compression stockings are still recommended. In thromboprophylaxis, the role of stockings in addition to anticoagulation is limited. For the maintenance phase of lymphoedema management, compression stockings are the most important intervention. Conclusion The beneficial value of applying compression stockings in the treatment of venous and lymphatic disease is supported by this document, with 19/25 recommendations rated as Grade 1 evidence. For recommendations rated with Grade 2 level of evidence, further studies are needed.

Rehabilitation of patients with venous diseases of the lower limbs: State of the art

BACKGROUND

To date, no document comprehensively focused on the complex issue of the rehabilitation of chronic venous diseases of the lower limbs.

METHOD

This article overviews and summarizes current strategies concerning venous rehabilitation of lower limbs.

RESULTS

Venous rehabilitation is based on four main strategies: (1) lifestyle adaptations and occupational therapies; (2) physical therapies; (3) adapted physical activities; (4) psychological and social support. Rehabilitative protocols must be tailored to the specific needs of each patient, depending on the severity of chronic venous disease and on the location and pattern of venous lesion(s), but also on age, motor deficits, co-morbidities and psychosocial conditions.

CONCLUSIONS

Venous rehabilitation consists of non-pharmacologic and non-surgical interventions aiming at prevention of venous disease progression and complications, reduction of symptoms and improvement of quality of life. Well-designed clinical trials are required to evaluate the efficacy of the described rehabilitative protocols in influencing the evolution of venous disorders.

The treatment of venous leg ulcers with a specifically designed compression stocking kit

Traditionally, venous leg ulcers are treated with firm nonelastic bandages. Medical compression stockings are not the first choice although comparative studies found them equally effective or superior to bandages. Patients, methods: We report on a multi-center randomized trial with 60 patients treated with either short stretch multi-layer bandages or a two-stocking system (Sigvaris® Ulcer X® kit). Three patients have been excluded because their ankle movement was restricted to the extent that they could not put on the stockings and 1 patient withdrew consent. Patient characteristics and ulcer features were evenly distributed. The proportion of ulcers healed within 4 months and the time to completion of healing were recorded. Subjective appraisal was assessed with a validated questionnaire. Results: Complete wound closure was achieved in 70.0% (21 of 30) with bandages and in 96.2% (25 of 26) with the ulcer X kit (p = 0.011). Ulcers with a diameter of up to about 4cm healed twice as rapidly, the larger ones as fast with the stocking kit as with bandages. The sum of problems encountered with bandages was significantly greater than that observed with the stocking kit (p < 0.0001). Pain at night and in the morning was absent with stockings but reported by 40% and 20% in the bandage group, respectively. The cardinal features associated with delayed or absent healing were ulcer size and pain. Conclusions: Common venous ulcers can readily be treated with the ulcer X compression kit provided the ankle movement allow its painless donning. Bandages, even when applied by the most experienced staff are less effective and cause more problems.

Self-management by firm, non-elastic adjustable compression wrap device [Translation of Druckmessungen unter Klettverschluss-Kompression - Selbstbehandlung durch feste, unelastische Beinwickelung]

<p>Severe forms of chronic venous insufficiency and lymphedema require strong compression-pressure, which exceeds the pressure exerted by medical compression stockings (&gt;40 mmHg). The aim was to investigate if patients are able to apply a Velcro-band compression device (Circaid Juxta Lite™) themselves with sufficient pressure. Thirty-one patients (CEAP C6=23, C5=5, C3=2, mixed ulcer=1) applied Juxta Lite™ on their own legs after a short instruction and were asked to readjust the pressure by their subjective feeling. Sub- bandage pressure was measured after application and 24 h later. In 30 patients without arterial occlusive disease the median sub- bandage pressure values on day 1 and day 2 were 44,5 mmHg (IQR 42-48), and 46 mmHg (IQR 44-48,25) respectively. One patient with an arterialvenous leg ulcer showed pressures of 34 and 36 mmHg. All measured pressure values corresponded to the pursued target range, demonstrating that adequate self application of Velcro bands is feasible and that patents can maintain this pressure by re-adjustment.</p><p><em>Source: this paper is an abridged translation of Mosti G, Partsch H.

A Polyphenol-Based Multicomponent Nutraceutical in Dysmetabolism and Oxidative Stress: Results from a Pilot Study

To assess short-term efficacy and safety of a multicomponent nutraceutical (MCN) on dysmetabolism and oxidative stress, a pilot prospective observational study was performed on 21 individuals (12 men and 9 women) who took, for 60 days, 2 tablets per day of an MCN based on antioxidants and metabolism regulators: hydroxytyrosol (15 mg), maqui (300 mg), amla (200 mg), monacolin K (10 mg), berberine (245 mg), astaxanthin (0.5 mg), coenzyme Q10 (100 mg), and folic acid (200 mcg). On day 0 (T0) and day 60 (T60), all participants underwent laboratory tests related to lipid profile, carbohydrate metabolism, oxidative stress, and cellular inflammation. Statistical analysis was applied to the resulting data. A significant improvement of most atherogenesis and oxidative stress biomarkers was recorded (mean figure at T0 and T60, p value): total cholesterol 243.50/194.83 mg/dl, p =.0002; low-density lipoproteins 174.50/124.58 mg/dl, p =.0001; glycemia 96.25/88.50 mg/dl, p =.035; total free radicals 306.44/280.93 U.Carr., p =.036; serum antioxidant capacity 2103.00/2246.06 umol/l, p =.0042; oxidized cholesterol 680.33/597.25 uEq/l, p =.0511. Insulinemia, microalbuminuria, high-density lipoproteins, C-reactive protein, and triglycerides had no statistically significant variation. Body weight and systo-diastolic pressure showed no significant change from T0 to T60. No relevant side effects were reported. The investigated MCN (Eonlipid), based on polyphenols, significantly improved the oxidative stress parameters and decreased the majority of atherogenesis parameters at short term. No significant side effects were reported. Further placebo-controlled studies should possibly corroborate the promising results of this pilot study.

Chronic venous disease - Part II: Proteolytic biomarkers in wound healing

Venous leg ulcers (VLU) are characterized by sustained proteolytic microenvironment impairing the healing process. Wound fluid (WF) reflect the biomolecular activities occurring within the wound area; however, it is unclear if WF from different healing phases have different proteolytic profiles and how VLU microenvironment affects the wound healing mechanisms. We investigated the proteolytic network of WF from distinct VLU phases, and in WF- and LPS-stimulated THP-1 monocytes treated with glycosaminoglycan sulodexide, a well known therapeutic approach for VLU healing. WF were collected from patients with VLU during inflammatory (Infl) and granulating (Gran) phases. WF and THP-1 supernatants were analyzed for nine matrix metalloproteinases (MMP) and four tissue inhibitors of metalloproteinases (TIMP) by multiplex immunoassays. Our results demonstrated that: 1) WF from Infl VLU contained significantly increased concentrations of MMP-2, MMP-9, MMP-12, TIMP-1, and TIMP-2 compared to Gran WF; 2) WF from Gran VLU showed significantly increased levels of MMP-1, MMP-7, MMP-13, and TIMP-4 compared to Infl WF; 3) LPS- and WF-stimulation of THP-1 cells significantly increased the expression of several MMP compared to untreated cells; 4) Sulodexide treatment of both LPS- and WF-stimulated THP-1 significantly down-regulated the release of several MMPs. Our study provides evidence-based medicine during treatment of patients with VLU. WF from Infl and Gran VLU have different MMP and TIMP signatures, consistent with their clinical state. The modulation of proteolytic pathways in wound microenvironment by glycosaminoglycan sulodexide, provide insights for translating research into clinical practice during VLU therapy.

A Review of Microvascular Measurements in Wound Healing

The microcirculatory evaluation in patients affected by arteriopathic or venous ulcers is usually carried out using laser Doppler flowmetry, transcutaneous oxygen (transcutaneous pressure of oxygen, TcPO2), and carbon dioxide (transcutaneous pressure of carbon dioxide, TcPCO2) measurements and capillaroscopy. These techniques provide significant pathophysiologic and prognostic information. TcPO2 and TcPCO2 diagnose and classify the extent of arterial disease in the leg ulcers caused by arterial disease; the prognostic value is recognized, though doubts about its prognostic potential exist in the case of leg ulcer. Laser Doppler flowmetry is able to identify the first functional impairment in the early stages of the arterial disease and in the complicated venous insufficiency. Capillaroscopy gives us morphological and quantitative parameters of the capillary bed that is damaged in arteriopathic and venous ulcers; nevertheless, it does not provide us with definite prognostic indexes. Combining the 3 methods may contribute to yield objective measures in the clinical management of lower extremity ulcers.
