Background:
The introduction of complex antiretroviral therapy has resulted in signifi cant decrease in the mortality rate of HIV positive patients, but it still remains unacceptably high, especially in some groups of patients.
Aim:
To investigate the death rate in patients with HIV/AIDS, lethality and mortality in co-infection, and the most common causes and predictors of fatal outcome, focused on early diagnosis and appropriate therapy.
Materials And Methods:
The study included 53 deceased patients with HIV/AIDS, monitored at the Clinic of Infectious Diseases in St George University Hospital, Plovdiv between 01.01.2010 and 31.12.2014. The methods of research included clinical analysis, laboratory tests, microbiological and serological tests (HCV, HBV, toxoplasmosis), ELISA, PCR. Statistical analysis was performed by descriptive statistics, the Student's t-test, the method of Van der Ward, and regression analysis (logistic regression).
Results:
During the study period 316 patients with HIV/AIDS were monitored, 53 of them with lethal outcome. Lethality was 16.7% for the whole group; in intravenous drug users - 13.8%; in co-infected patients: HIV/M. tuberculosis - 46%, in HIV/HCV - 17.8%. Lethality and mortality in HIV(+) patients with co-infections in populations of diff erent age, gender, duration since starting сАRТ and degree of immunodefi ciency (according to CD4, VL) was compared with the lethality and mortality in patients with these conditions from the general population.
Conclusions:
Fatal outcome in patients with HIV/AIDS was most commonly associated with co-infections HIV/M. tuberculosis and HIV/HCV. Predictors of a fatal outcome are pulmonary tuberculosis, advanced immunodefi ciency with VL> 500 000 c/μL and CD4 <100/mm3, absence or non-systemic antiretroviral therapy.

Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
