Study on the Therapeutic Efficacy of a Polyphitho Therapeutic Compound in Primary and Secondary Lymphedema

Introduction

Primary and secondary lymphedema therapy improves the patient's quality of life in the long term, given the chronic nature of the pathology.^1–4 The various therapeutic proposals, often administered as associations, demonstrate the limits that are observed in clinical practice with respect to these pathological conditions. Surgical treatment, in its various techniques proposed, still shows a high percentage of therapeutic failures (substantially a postoperative immobility) and still today it is not possible to identify patients who are candidates to experience a certain clinical improvement after surgery. ⁵ Physical therapy requires periodic interventions and continuous clinical monitoring that can demonstrate the maintenance of the results obtained thanks to the therapy for shorter or longer periods, this aspect being strongly conditioned by the wearing of an elastic garment for long periods.^6,7 Drug therapy uses the two categories of benzopyrones^8,9: alpha-benzopyrones ¹⁰ (to which coumarins belong) and gamma-benzopyrones (to which bioflavonoids belong). ¹¹ The therapeutic effect,^12,13 not constant, dose dependent and strongly conditioned by the individual response of single patients is highlighted essentially in the I and II clinical stage, when fibrosis has not yet entirely conglobated also the wall of the initial lymphatic vessels and lymphatic collectors that, under these conditions, no longer respond to pharmacological stimuli.^14–20 This study stems from the need to ascertain the effect of Lymdiaral in the cases of primary and secondary stage I and II lymphedema, also considering the multiple effects of the compound both with respect to chronic inflammation (involving the tissues in these clinical forms, which also structurally disrupt the interstitial matrix, a fundamental biological network between cells and vessels and nerves) and toward the resorption of interstitial fluids, the reduced capillary permeability, and the overall draining action.^21,22 The Matrix itself, for too long considered only an “inert tank,” is today seen as a fundamental component in the biological processes of cellular and tissue exchange and remodeling; as a matter of fact, all the fundamental disease categories are born and developed at a matrix level: acute and chronic inflammations, chronic degenerative diseases, dysplasia, and even neoplasms. A fundamental role of physiological and functional balance must be safeguarded, mainly from the oxidative processes that determine aging and loss of function. Hence the need, in a chronic pathology such as lymphedema,^23–28 to resort to active principles capable of keeping the equilibrium of the Matrix alive and vital in its work of continuous and dynamic biofunctional remodeling. ²⁹

Materials and Methods

One hundred thirty-six patients (120 women with a mean age of 54.6 years and 16 men with a mean age of 59.1 years) with primary lymphedema were studied (69, 63 women and 6 men) and secondary lymphedema (67, 56 women and 11 men). One hundred ten (97 women and 13 men) involved the lower limbs and 26 (23 women and 3 men) the upper limbs. Eighty-four (79 women and 5 men) presented a I clinical stage; 52 (41 women and 11 men) a II clinical stage. The following inclusion criteria, more selective than in previous literature, were identified in the study:

- Age between 18 and 70 years (average age 56.4 years)

The following exclusion criteria have also been identified:

The average height of the subjects examined was 165 cm in women and 170 cm in men; the average weight 66.9 and 77.6 kg, respectively. The average body mass index (BMI) was 24.8 in women and 26.7 in men.

All patients underwent a 15-day washout from any specific vasoactive therapies taken for a long time.

All the patients were given 20 drops three times a day for 90 consecutive days of a compound thus constituted (and, reported on the side, there are the daily dosages of each component distributed in the three administrations):

The following parameters were examined before starting the treatment (T0) and at the end of treatment (T1):

In particular, the circumferences in basal conditions and after 90 days of treatment were detected at the following points of reference:

Results

At the end of the 90 days of treatment the checks of the various parameters taken into consideration have demonstrated the following results:

- High-resolution ultrasound probe measurements of the suprafascial thicknesses of the affected limbs have shown an average decrease in the measurements compared with the basal values of 11.5% (12.1 for the upper limb, 11.1 for the lower limb) ±8.1% (Fig. 1).

- In relation to the SF12 quality-of-life questionnaire it was noted in particular that:

With reference to pain as an obstacle to work performance, the percentage of “in no way” responses after treatment has risen to 58.6% compared with 44.1% of responses before the start of treatment with a simultaneous decrease in “much” from 6.3% to 1.8% (Fig. 2a, b). OPEN IN VIEWER

The same limitation in activities that require a moderate physical effort showed a decrease in the response “very limiting” from 14.4% in basal conditions compared with 5.4% after treatment with a simultaneous increase in the response “not limiting” that in basal conditions was 21.6% and became 34.2% after treatment (Fig. 3a, b).

In relation to the overall health status (cenesthesia) at the end of treatment, there was a 15.4% increase in the response “excellent” compared with the basal conditions with a simultaneous decrease in “poor” from 16.8% to 4.9%.

- The BMI did not undergo substantial changes both in the primary and secondary forms of lymphedema (regardless of the location in the lower or upper limbs). The average decrease of 0.9% in the value, found at the end of treatment, judged “not significant” was also linked to the greater physical activity performed on average by the subjects and to the respect of improved dietary regimes. Furthermore, the change in BMI was not influential in the modifications of the lower limbs, whereas it showed a greater influence in the circumference decreases related to the locations in the upper limb.

- In relation to the final circumferences found at the various levels established in the study, an average decrease of 9.8% was found with greater evidence in women compared with men and in the youngsters compared with elderly (both for the forms affecting the lower and upper limbs) (Figs. 4–6).

Discussion and Conclusions

The results on the efficacy of the product are rather encouraging in the control of inflammatory, postsurgical, and primitive enema. The beneficial actions were also useful in the management of pain and symptoms related to edema, making patients more adherent to the medical, physical, and surgical therapies they must or will undergo. The increase in relational abilities, in the long and troubled therapeutic course of lymphedema characterized by exacerbations, recurrences, and sometimes therapeutic failures, allows better clinical results and a significant increase in quality of life.

To date, the natural active ingredients do not replace (nor are they intended to do so) the physical or surgical therapies improved over the years, which at least reduce the worsening of chronic lymphedematous pathology; if anything, the association of these substances to physical therapy, which may precede or follow any surgical treatment, shows the best results with regard to the containment of edema and the related symptoms.

Furthermore, the presence on the market of formulations, which in a single mixture offers a synergistic therapeutic action against phlogosis, pain, tissue oxidation, and the aging of the interstitial matrix (due to the increasing fibrosis) makes pharmacological therapy affordable on the term by almost all patients.

The observations showed stability in the results and the patients continued with the therapy. It was not necessary to carry out a water balance because the indirect diuretic effect also includes protein reabsorption.

The action mechanisms of the single constituents of the compound determine an exclusive overall effect on the interstitial matrix improving its function of biological network, both for the overall anti-inflammatory and draining result.

In the literature, and the clinical results obtained in this study together with the improvement of the quality of life achieved (with the possibility of reducing costs for patients) and the excellent biological tolerability, allow us to advise and extend the combined use of the product with physical therapy to all patients suffering from lymphedema, regardless of its genesis, to obtain the best clinical result, without obviously getting complete recovery from the disease, as no treatment currently available can do. Regarding biological tolerability, the control tests did not show any type of negative side effect on liver and kidney function, nor on myelopoiesis.

The study was appropriately conducted on patients presenting I and II clinical stage lymphedema as in stage III tissue fibrosis that is established at a local level prevents the same substances from acting, above all with the anti-inflammatory effect, given that, in those anatomical conditions, the entire structure of the lymphatic collector is anatomically involved in the fibrosclerotic process developed in chronic progressive forms. This preliminary study demonstrates incontrovertible clinical effects that, however, must be investigated with more numerous and more varied case studies from the point of view of the representativeness of the two genders and of the clinical localizations.
