Cytostatic illness

Cytostatic illness — a complex of the syndromes developing at use of intensive cytostatic care, caused by its toxic influence on various phases of a cellular cycle.

The cytostatic illness often meets in oncohematological practice as the aspiration to gain necessary medical effect is followed by various collateral manifestations caused by toxic influence of the used antineoplastic himiopreparat.

Etiology and pathogeny
Expressiveness of a cytostatic illness depends on a number of circumstances, generally on a dose of the applied means, duration of treatment, ways of their introduction and sensitivity of various cells of an organism to their toxic action (for example, Vincristinum most damages a peripheral nervous system, Cyclophosphanum — an epithelium of a digestive tract and skin, anthracyclines — a myocardium etc.).

All himiopreparata affect mainly the sharing cells owing to what arise miyelodepressivny, dispepsichesky, hepatic, immunodepressive and other syndromes.

There is a tropnost of drugs to this or that cellular line. Vincristinum toxic influences on granulotsito-and a monocytopoiesis, Dopanum, leukeranum, Degranolum, vinblastine, Natulanum and Cyclophosphanum — a lymphocytopoiesis; sarcolysine, Amethopterinum, 6 Mercaptopurinum, Cytarabinum and daunomitsin to the same extent suppress granulo-and a lymphocytopoiesis. Possess thrombocytopenic action miyelobromol, Bruneomycinum, rubomitsin.

Vincristinum and rubomitsin give myelotoxic effect in 4 — 7 days and its duration makes from 7 to 10 days, limfotoksichesky action of Natulanum is shown only in 25 — 36 days after the beginning of therapy and 2 — 3 weeks can remain.

Definition of a state can be considered as factors of increase of risk of development of a cytostatic illness. So, disturbance of zhelchevydelitelny function of a liver leads to accumulation in plasma of the himiopreparat allocated with bile; at a renal failure concentration in blood of drugs and their metabolites owing to their broken removal with urine increases; the cachexia is followed by increase of a catabolism and disturbance of exchange processes.

On expressiveness of a combination of various clinical syndromes of a cytostatic illness allocate easy, average and heavy its forms.

Approximate formulation of the diagnosis:
The cytostatic illness at an acute miyeloblastny leukosis owing to use of modern programs of polychemotherapy which was complicated by pneumonia and sepsis.

In the table the characteristic of clinical syndromes of a cytostatic illness is provided. At a combination of myelotoxic, dispepsichesky and immunodepressive syndromes danger to life of the patient increases. In development of a cytostatic illness the organospetsifichnost of cytostatic means matters. So, as a result of hepatotropic action of himiopreparat (L-asparaginase, a methotrexate, 6 Mercaptopurinum, Cytarabinum, Myelosanum) there can be disturbances from the fast-taking place functional frustration to toksiko-allergic hepatitis with the phenomena of a liver failure. Cardiotoxicity can be caused by antineoplastic antibiotics of group of anthracyclines, Vincristinum possesses a neurotoxicity.

Moderate hair loss, xeroderma

Reversible alopecia, skin peeling, formation of vesicles, itch

Irreversible alopecia, necroses, dermatitis


The localized infections

Heavy extensive infectious and inflammatory complications

Heavy it is purulent - necrotic processes, sepsis


Verification of the diagnosis
The cytostatic illness is diagnosed on the basis of a complex of characteristic syndromes.

Treatment of a cytostatic illness

In therapy of a miyelodepressivny syndrome at a cytostatic illness the main place belongs to haemo component therapy.

The Dispepsichesky syndrome demands active disintoxication treatment, correction of a water salt metabolism. The enveloping and adsorbing means (white clay, Almagel, Enterodesum), the astringents (broths of a St. John's Wort, a camomile, oak bark, bismuth drugs), the antiseptic and antibacterial drugs, means normalizing flora of a digestive tract, influencing a peristaltics (cerucal), fermental drugs are applied (panzinorm, festal, digestal). In hard cases temporarily resort to parenteral food. In cases when ulcer and necrotic damage of a mucous membrane of a digestive tract is complicated by perforation, there can be a question of surgical intervention.

At the expressed abnormal liver functions cancel antileukemic means and appoint active gepatozashchitny therapy (5% glucose solution, Haemodesum, Prednisolonum, a diet); at disturbances of belkovoobrazovatelny function transfusions of albumine, a plasma concentrate are shown. Beneficial effect is exerted by hyperbaric oxygenation.

Cardiotoxic influence of cytostatic drugs demands their cancellation and the corresponding cardiological correction against disintoxication therapy and the rational mode.
At nephrotoxic complications intravenous administrations and appointment in neutral and subacidic liquids, a diet, use of the uroseptic and removing uric acid drugs are shown (Allopyrinolum).

At infectious and infectious and necrotic processes the combination of antibiotics of a broad spectrum of activity and immune drugs (immunoglobulins, immune plasm) is used. At development of viral infections — antiviral drugs (zaveraks); at fungal — antifungal means (Amphotericinum In, nystatin).

At skin infections use antiseptic, antibacterial, immune drugs, surgical treatment of wounds. Toxic defeats of a nervous system will most difficult respond to treatment.
