[Analysis of tuberculosis mortality in Armenia]. / Analiz smertnosti tuberkulezom v Armenii.

The outpatient and patient histories were analyzed in 198 dead patients with tuberculosis. Particular concern is caused by an increase in mortality due to tuberculosis within a month after its detection. Clinically, there are predominant patients with progressive destructive forms of the disease. A total of 86.4% of the patients died directly from tuberculosis and its complications, the remaining (16.6%) patients died from other non-tuberculous diseases. The main cause of death from tuberculosis was its progression (50.1%), cardiopulmonary failure (34.3%), pulmonary hemorrhage (9%). A combination of several causes of death was noted in 33.1% of the patients who died from generalized tuberculosis.

[Epidemiologic situation of tuberculosis in Armenia under the present condition]. / Epidemiologicheskaia situatsiia po tuberkulezu v Armenii v sovremennykh usloviiakh.

The epidemiological situation in Armenia is very grave: the tuberculosis cases registered in 1994 are 19.6 per 100,000 inhabitants, this is 16.6% higher than the figure in 1993. Mortality rates in 1994 are 3.1 per 100,000 persons. Morbidity in males is 2.5 times higher than that in females. The greatest proportion of the first cases detected is in the age group of 25-34 years. Infiltrative tuberculosis with multiple decay and its acute course is prevalent in the pattern of tuberculosis morbidity. Activities in prophylactic measures drastically has declined due to power crisis and grave socioeconomic conditions of the republic. Groups of migrants as potential carriers of undiagnosed tuberculosis forms are gaining a great significance among patients with tuberculosis.

[Class I and II antigens and levels of IgG antibodies in patients with infiltrative tuberculosis of the lungs]. / Antigeny I i II klassa i uroven' IgG-antitel u bol'nykh infil'trativnym tuberkulezom legkikh.

Sixty patients with infiltrative tuberculosis of the lungs showing different dynamics of the process were examined. In the patients with unfavourable process of the disease antigens A2, B13, B16 and DR2 were more frequent than in the patients with favourable process of the disease in whom antigens A9, B12, Cw4 and DR5 were more frequent. It suggested that the presence of antigen DR2 was a certain risk factor as to development of tuberculosis and its presence in tuberculous patients could indicate unfavourable outcome of the disease. The levels of the specific antituberculous antibodies to PPD were also indicative of favourable and unfavourable processes of pulmonary tuberculosis.
