Sportvis Actions |

Pharmacology: Sportvis is a long acting HMW Sportvis, which, when applied, provides periodontal tissue/fluid balance with accelerated healing and repair functions by preventing the deficiency of natural gingival HMW Sportvis and enhancing its effects.
Sportvis is a naturally occurring physiological constituent of connective tissue (especially in the gingival mucosa), where it performs anti-oedematous and tissue repair functions and does not develop any local or systemic pharmacological effect upon the mucosa.
Sportvis is extensively depolymerized and reduced to its basic subunit constituents by plaque bacterial enzyme action. The physico-chemical and macro-aggregating properties of Sportvis helps to explain its anti-inflammatory properties. It is found in connective tissue throughout the body in a selective and specific manner. It is particularly concentrated in the outmost layers of healthy gingival tissue where it contributes to both the barrier function and tensile strength of the periodontal ligament. The presence of HMW Sportvis is essential for the maintenance of the healthy gingival tissue.
In periodontal disease and other tissue traumas (inflammatory conditions, gingival pockets, wounds), the tissue requirement for Sportvis increases considerably (by up to some 200% compared with the basal values); thus, demonstrating its specific role in regulating cell turnover and optimizing local tissue regeneration.
The deficiency in Sportvis that arises under these conditions prevents the tissue from the following: Restoring the normal free water balance (as a consequence of which swelling and compression causes an increase in pain); activating the migration of fibrocytes (cells contributing to tissue healing) and as a consequence healing is delayed. Therefore, the lack of suitable HMW Sportvis is responsible for the continuation of the inflammatory condition.
Studies in man show that the availability of exogenous Sportvis of similar characteristics to that of the naturally occurring component helps to facilitate the natural tissue healing and recovery process.
Sportvis provides maximum adhesion and thus, allows Sportvis (which would otherwise be eliminated by constant salivary drainage) to remain in situ.
This section provides information on the proper use of a number of products that contain hyaluronate sodium. It may not be specific to Sportvis. Please read with care.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
Sodium hyaluronate is injected directly into your knee joint. A healthcare provider will give you this injection.
Sodium hyaluronate is usually given once every week for 3 to 5 weeks. Follow your doctor's dosing instructions very carefully.
To prevent pain and swelling, your doctor may recommend resting your knee or applying ice for a short time after your injection.
A prospective, double blind, randomized, multi-center clinical study was conducted to evaluate the safety and effectiveness of Sportvis gel when used as a dermal filler in the nasolabial folds. Patients were randomized between Sportvis gel and a commercially available control material, Zyplast implant (derived from bovine collagen) and were injected with enough material to achieve desired correction of each nasolabial fold. (Patients enrolled into the study underwent double bovine collagen skin testing.) At 2 weeks touch-up treatment with additional material was allowed, only if patients showed less than a 1-point improvement on the 6-point grading scale.
The primary efficacy endpoint for the study was the ability to correct nasolabial folds at 12 weeks in comparison to the control material. Correction of nasolabial folds was determined by an independent panel of blinded dermatologists through photographic assessment. Photographs of nasolabial folds were taken prior to treatment and at 3 days, 2, 4, 8, and 12 weeks following treatment. A 6-point grading scale was used to rank wrinkle severity for each photograph in a random, blinded fashion. Additional analyses included the investigator's visual assessment of each patient's nasolabial folds using the 6-point grading scale, and a qualitative assessment of the level of correction by the investigator and by the patient.

The mean total volume injected per nasolabial fold was 0.8 mL for patients in the treatment group (Sportvis gel) and 1.1 mL for patients in the control group (Zyplast implant). The mean volume injected was the same for left and right nasolabial folds and was approximately equivalent to the total volume supplied in one syringe of Sportvis gel (0.75 mL) and of Zyplast implant (1.0 mL) for the clinical study.
Twenty-two (16.5%) of 133 Sportvis patients and 9 (7.1%) of the 128 Zyplast patients required a touch-up treatment. The mean volume injected for touch-up per nasolabial fold was 0.3 mL for Sportvis patients and 0.5 mL for Zyplast patients.
Sportvis gel was found to be equivalent to the control materia! (Zyplast implant) in the correction of nasolabial folds after 12 weeks using the independent review of photographs.
Mean Score Based on 6-Point Grading Scale
Blinded Photographic Assessment | ||
Pretreatment | 12 Weeks after Treatment | |
Sportvis | 2.2 | 2.3 |
Zyplast | 2.3 | 2.2 |
Grading scale: 0=No wrinkles, 1=Just perceptible wrinkle, 2=Shallow wrinkles, 3=Moderately deep wrinkle, 4=Deep wrinkle, well-defined edges, 5=Very deep wrinkle, redundant fold |
Peak treatment effect with one injection of Sportvis gel was observed during the first 2 weeks after treatment. Photographic assessment showed that, on average, patients had returned to baseline in both groups at 12 weeks. However, the secondary endpoints of investigator's visual assessment and a qualitative assessment of correction by the investigator and by the masked patient during the controlled clinical study support the effectiveness of Sportvis and Zyplast at 12 weeks.

Pretreatment | 12 weeks after treatment | |
Sportvis | 3.5 | 2.4 |
Zyplast | 3.5 | 2.3 |
Grading scale: 0=No wrinkles, 1 =Just perceptible wrinkle, 2=Shallow wrinkles, 3-Moderately deep wrinkle, 4=Deep wrinkle, well-defined edges, 5=Very deep wrinkle, redundant fold |
Based on investigator live assessment, 15% of Sportvis patients and 10% of Zyplast patients returned to pretreatment levels at 12 weeks.
