Evaluation of Safety and Pharmacotherapeutic Efficacy of Cycloferon in Treatment of Astrakhan Rickettsial Fever
Abstract
Clinicopathogenetic impact of cycloferon, an endogenous interferon inductor, on the process of Astrakhan rikettsial fever, its complications and outcomes was analysed. The treatment scheme with addition of cycloferon to the complex therapy was optimized. The specificity of the disease clinical process and the level of the interferon status in the patients treated with cycloferon alone or with combination of the standard therapy and cycloferon was shown. It was observed that in the patients with moderate severity of the disease the combined use of the standard therapy and cycloferon was in favour of arresting the disease clinical signs (fever, headache, weakness, eruption, hepatomegaly, arthralgia and myalgia, lymphatic gland inflammation, primary affect) and lowered the hospitalization term vs. the standard therapy alone. In the patients with moderate severity of the disease the levels of the serous interferon-α before the treatment were found lower, while those of interferon-γ were higher. The use of cycloferon in the treatment scheme resulted in increase of the interferon-α levels and decrease of the higher levels of interferon-γ. The standard therapy in combination with cycloferon in the patients with moderate severity of the disease provided changes in the immune status: increase of the relative content of T- and B-lymphocytes and normalization of their absolute number. Normalization of the phagocytic activity and the coefficient of the active phagocytes, as well as increase of the phagocytic index, the levels of immunoglobulins G, A and M and the number of the circulating immune cells were stated. The standard therapy with addition of cycloferon resulted in normalization of the levels not only of succinic denydrogenase, lactate dehydrogenase and glucose-6-dehydrogenase but also of alpha-naphthylacetate esterase and alpha-naphthylbutirate esterase in the neutrophils, as well as of the whole spectrum of the monocyte enzymes, except NAD-diaphorase. The adverse reactions were observed in 2.5% of the cases (9 subjects). All of them were mild and did not require discontinuation of the drugs use.
