Effect of cetuximab on development of viral infectious complications in laryngeal cancer.

e17578 Background: Cytostatic treatment was shown to influence significantly reactivation of latent viral infections. Our purpose was to study the possible effect of cetuximab on activation of herpesvirus infections. Methods: The blood serum of patients with histologically confirmed laryngeal squamous cell carcinoma was studied before and after chemotherapy. The main group included 9 pts receiving cetuximab+cisplatin+5-fluorouracil, the control group – 9 pts, cisplatin+5-fluorouracil. Antibodies (AB) against viral proteins were detected by ELISA. Results: 6 (66.7%) pts of the main group had primary advanced cancer, 3 (33.7%) – recurrent laryngeal cancer; in control group - 7 (77.7%) and 2 (22.2%), respectively. All pts in both groups were seropositive for HSV 1,2, CMV and EBV before chemotherapy; 4 (44.4%) pts in main group and 7 (77.8%) controls were HPV 6 seropositive. Serological markers of activation of herpes virus infection (IgM or IgG against early viral proteins) after chemotherapy were detected in the main group in 8 (88.9%): HSV 1,2 - 5 (55.6%), CMV - 2 (22.2%), EBV - 3 (33.3%). HSV 1,2, CMV and EBV infections in the control group were activated equally often and found in 3 (33.3%) pts. Clinical signs of herpes virus infection were not observed in either group. A sharp decline in AB titers, sometimes up to their complete disappearance, was registered in 3 (33.3%) pts in the main group and in 6 (66.7%) controls. 1 pt of the main group showed a decline in EBV AB titers and absence of HPV 6 AB titers, 1 pt - a decline in CMV and EBV AB, 1 pt - a decline in HSV 1,2, CMV and EBV AB and absence of HPV 6 AB titers. 2 pts of the control group showed a decrease in HPV 6 AB, 2 pts – their absence, 2 pts – absence of HPV 6 AB and a decline in HSV 1,2, CMV and EBV AB. It could be associated with a greater degree of bone marrow hematopoiesis inhibition during cytostatic therapy. Lymphopenia was registered in the control group more frequently than in the main one. Conclusions: Cetuximab inclusion into chemotherapy does not have an additional negative impact on the development of viral infectious complications. A higher rate of registration of specific antibodies typical of the acute infection phase in the cetuximab group could indicate an adequate response to viral infection.

Aim. Study the role of herpes viruses and pneumocystis in infectious complications in children from HIV-infected mothers. Materials and methods. Sera and blood cells from 59 children from HIV-infected mothers were studied for the presence of various markers of herpes virus infections and pneumocystosis by a complex of methods of modem laboratory diagnostics. Results. Frequency of detection of markers of herpes virus infection was from 10% for chicken pox in children with non-final HIV test to 93% for herpes simplex virus in HIV-infected children from closed organized groups. Signs of active infection in children with laboratory confirmed HIV infection were diagnosed 2.5 times more frequently for HSV infection and chicken pox and 1.8 times more frequently for HHV-6 and pneumocystis than in children with non-final HIV test. Markers of various disease stages with opportunistic infections (01) were detected in children with confirmed HIV-infection: primary acute and latent forms of the infection, reactivation, reconvalescence, whereas in children with non-final HIV test maternal antibodies against herpes virus and pneumocystis predominated. Markers of active infections excluding HSV and HHV-6 were more frequently detected in children from families than in children from closed organized groups. Conclusion. The feature detected - a lower percentage of detection of markers of active forms of 01 in HI V-infected children from social institutions - is determined by the fact that observation of these children is carried out by medical personnel that have the knowledge and experience of prophylaxis of infectious complications in HIV-infected children, whereas quality anti-epidemic regimen is frequently not maintained regarding home children with HIV infection. Another factor facilitating spread of opportunistic infections is the asocial lifestyle of most of the examined families. These data dictate the necessity of enhancement of anti-epidemic regimen and prophylaxis of opportunistic infections in family loci. Not only HIV-infected children, but also all the family members should be examined for markers of herpes virus infection and pneumocystosis in order to detect sources of the infection and timely execution of the prophylaxis measures.

The objective: to evaluate the social and health aspects of the association of HIV and herpes infections (GVI) in pregnant women. Patients and methods. Clinical and statistical analysis of 1177 individual cards of pregnant women with HIV for 5 years. The control group consisted of 200 pregnant women with physiological pregnancy. Results. Analysis of individual cards of pregnant women with HIV found insufficient to TORCH-infection survey (74,7%). The frequency of herpes infections in HIV-infected patients was 42,3%. The most common laboratory revealed HSV1/2 – 41,9%, CMV – 22,4% and mixed infection (both HSV1/2 and CMV) – 28,1%, other types of AIT is quite rare. At 8,5% of pregnant women stated primary infection herpes viruses, 27,2% – the reactivation of infection. HIV infection is often associated with other infections: hepatitis, fungal infections, toxoplasmosis, papillomavirus infections, respiratory infections, infections of the genitourinary system. Fixed low social status of HIV-infected women with AIT, the presence of harmful habits, a high frequency of co-infections and low compliance to treatment, are additional factors of perinatal risk. History data indicate a high rate of abortions and missed abortion in women with HIV infection and GVI. Going the way of HIV infection with parenteral on sex strengthens the role of herpes virus infection as a cofactor transition from HIV to AIDS, and the development of perinatal complications. The current pregnancy burdened with 84,3% of women: high incidence of placental insufficiency (41,3%), the threat of miscarriage and preterm labor, fetal distress. Maternal mortality in 5 years was noted in 2 cases (0,1‰), both women were GVI, perinatal – in 12 cases, 8 (21,5‰) of them women with AIT. 12,1% of children were born in a state of severe asphyxia, malnutrition with 31,3%, from 3,8% of the children at the end of 1st day intrauterine diagnosed pneumonia. Conclusions. The high frequency of co-infection of HIV and herpes viruses, joining other infections and comorbidity in these women, their low social adaptation, and susceptibility to treatment, the negative impact of herpes infection in the course of HIV infection, the condition of women during pregnancy, the fetus and the newborn, which requires individual approach to the management of women based on established medical and social aspects of the problem.
