tetrachlorodecaoxide and Skin-Ulcer

Extravasation of some cytostatics applied i.v. can often cause local edema with skin redness, thrombophlebitis and not infrequently skin necrosis with chronic ulcera. Local treatment is usually ineffective, and so far surgical excision of ulcera is the only curative approach. Tetrachlorodecaoxygen anion complex (TCDO) has shown high activity in healing chronic leg ulcera, by increasing pO2 in hypoxic wound tissue and stimulating phagocytosis as one of anti-inflammatory processes To study the local activity of TCDO in tissue necrosis and chronic ulcera caused by cytostatic extravasation, 23 patients with local skin complications underwent local treatment with TCDO, made as isotonic water solution. Seventeen patients experienced only local edema with redness, while 6 patients showed deep chronic ulcera. All the skin changes were complications after i.v. doxorubicin, cisplatinum, dactinomycin or vinblastine application. The treatments with TCDO followed 1-3 months after ulcera appeared, while skin inflammations were treated 1-8 days after they occurred. TCDO was applied locally twice a day by impregnated cotton tissue for 4-6 weeks. Evaluable were only measurable lesions. From 17 patients with only skin inflammation 3 patients obtained complete resolution, 8 partial resolution and 6 had stable lesions. Thus, overall response was recorded in 65% of patients (11/17). In 6 patients with deep chronic ulcera a longer treatment (6 weeks) was needed, and in 5 of them the complete epithelization and resolution occurred. One patient had a partial wound healing. No side effects of treatment were observed. The effect of locally applied TCDO in chronic ulcera seems to be preferable to surgical treatment. A controlled study will show the exact therapeutic value of this new anti-inflammatory compound.

Local tetrachlorodecaoxygen anion complex (TCDO) had three therapeutic effects in difficult wounds, substantiated on day 14 in a multicentre double-blind randomised clinical trial on 271 inpatients with 0.9% saline as control. Wound cleansing was intensified, the formation of new tissue (granulations, epithelium) was promoted, and, irrespective of the different wound types, wound surfaces decreased more quickly, by a factor of 2.4. A novel quantity (eta) was derived as an indicator of wound healing promotion. eta NaCl (= -0.14) did not differ among different wound diagnoses. eta TCDO values were significantly better in relation to wound diagnosis, to smear (detritus), and to epithelialisation. Local TCDO was well tolerated.

63 transcutaneous measurements of oxygen pressure and 36 series of infrared thermograms in 9 hypoxic wounds showed that topical administration of tetrachlorine decaoxide (TCDO) results in increased oxygen supply of the wound. This effect is associated with improvement of the skin temperature and decrease of the pathological temperature difference between the wound and the surrounding tissue. TCDO can induce physiological wound healing, since it improves the mechanisms of the immune defence system, wound cleansing, granulation, and epithelialization in slow-healing wounds.
