Abstract. Tuberculosis is one of the leading causes of illness and death in the world. Despite constant improvement in diagnosis, its rapid establishment remains a challenge in signifi cant number of cases. Culture identification of M. tuberculosis remains the gold diagnostic standard. That, however, takes more than two weeks and its diagnostic sensitivity does not exceed 80%. In childhood rapid diagnosis and prompt initiation of specifi c treatment are essential. According to the literature, a very small part of children (8-15%), suffering from tuberculosis, are spreading the infection, meaning that in the children population is diffi cult to fully count on cultural results. Fast diagnosis of tuberculous infection is also diffi cult when tuberculous bacteria cannot be detected in sputum or gastric lavage smears with direct microscopy. For more than ten years now imununological test – IGRA (IFN-gamma Release Assays) tests – QuantiFERON, TSPOT. TB are successfully used in clinical practice for diagnosting of the infectious of the macroorganism with M. tuberculosis. Their main advantage is high specifi city (97.1% [95% CI: 86.8-99.9% for T-SPOT.TB) and sensitivity (95.6%) in patients with active tuberculosis. They are usually performed using venous blood from the patient. Other body fl uid specimens like bronchoalveolar lavage, pleural effusions and cerebrospinal fl uid are successfully used for immunological studied as well. Although not routine in clinical practice T-SPOT.TB offers fast local identifi cation of tuberculous infection and disease. Irrespective of the invasive nature of the method, local immunodiagnosis (using BAL) is a promising and fast method for diagnosis of tuberculous disease in suspected children otherwise negative on sputum and gastric lavage material smears.
Key words: tuberculosis in children, immunological diagnosis, T-SPOT.TB in blood, T-SPOT.TB in bronchoalveolar lavage

Abstract. The review summarizes current accumulated data from molecular genetic studies of hepatitis virus C. The results are interpreted from the perspective of infectious epidemiology. The biological characteristics and specifi cally the genetic variants of the virus are examined according to epidemiological criteria. The historical aspects of the transfer of this bio-pathogen in the different geographic regions have been traced. The contemporary global distribution of the major genetic types, subtypes and quasi-species is shown. On this basis, the endemicity of the viral hepatitis C disease is rationalized in its current stage of development. The perspectives for optimization of the epidemiological theory and prevention of HCV through the use of molecular genetic methods have been discussed. The validation and widespread application of such diagnostic approach will lead to utmost tangibility of the epidemiological research with scientifi c or practical focus.
Key words: hepatitis C virus, molecular epidemiology, evolution, distribution

Abstract. HIV infection continue to be serious problem for Europe, particularly in the Eastern part of the European Region. In 2016, more than 160,000 people were diagnosed with HIV infection – once again the highest annual number for the Region. The vast majority of the new cases – 80% were diagnosed in the East and 18% in EU/EEA. The data presented in this review show worrying signs to increase over the past 10 years the number of new diagnosed cases with HIV infection in the part of East and Central Europe and the trend of stabilization and decreasing morbidity through recent years in some Eastern European countries and countries of EU/EEA. In Bulgaria in 2016 are registered 202 cases of HIV infection, with which the total number of HIV carriers it is offi cial 2505.

The Niemann-Pick disease - Bulgarian medical journal (Български медицински журнал), 11, 2017, № 3, 29-32.

Kr. Koev
Department of Emergency Medicine, Medical University – Sofia
Abstract. The review describes the rare genetic disease of progressive nature  Niemann-Pick disease (NPC). Typical of this disease is the lack of the enzyme named acid sphingomyelinase (ASM), which degrades sphingomyelin, and because of that the lipids are accumulated abnormally in the cells of different body tissues. The individuals with NPCs have mutations in one of the two genes – NPC1 or NPC2. Type A of the disease is severe and with poor prognosis and high lethality. An ocular anomaly called a cherry-red spot occurs in peoples affected by the type A of Niemann-Pick disease. Typically, lung infections and thrombocytopenia are observed in patients with the type B of NPC, and about 1/3 – ocular anomalies (cherry-red spots) or neurological lesions. Treatment is targeted at specifi c symptoms in each individual. Swallowing diffi culties should be regularly monitored and the risk of aspiration should be assessed.
Key words: hepato-/splenomegaly, vertical supranuclear gaze palsy, cherry-red spot, acidic sphingomyelinase, deafness

Toxicology


Sacred plants and mushrooms with psychoactive properties and their use throughout the centuries - Bulgarian medical journal (Български медицински журнал), 11, 2017, №2, 7-14.
J. Radenkova-Saeva

Toxicology Clinic, UMHATEM “N. I. Pirogov” – Sofia
Abstract. Some psychoactive substances have been used in religious ceremonies, shamanic and spiritual rituals since prehistoric times. There is archaeological evidence for the use of psychoactive substances, dating back at least 10,000 years. Most often these are herbs, plants and fungi, which are representatives of hallucinogenic and other substances with psychoactive properties. The author presents some of the traditional „sacred plants“ and active substances with psychoactive properties: cannabis, coca, kykeon, iboga, soma, peyote, ayahuasca, еrginе, “the magical” psilocybe mushrooms, opium and their use throughout the centuries. Although some psychoactive substances are taboo, and most of them are banned in the Christian and Islamic societies, their presence and significance in terms of the spiritual traditions of different cultures is undisputed.
Key words: psychoactive substances, sacred plants, mushrooms, hallucinogens

Abstract. Infl ammatory bowel disease (IBD) includes various intestinal pathologies, the most common of which are ulcerative colitis (UC) and Crohn’s disease (CD). Both, UC and CD, are manifested clinically with similar symptoms which may include diarrhea, rectal bleeding, abdominal pain and weight loss. Anemia is one of the most common symptoms of infl ammatory bowel disease. The pathophysiology of anemia in IBD is complex and may be associated with infl ammation, intestinal bleeding or impaired iron absorption. Other less frequent causes are vitamin B12/folate defi ciency or drug-induced anemia. Recent data suggests that hepcidin is a major mediator of anemia and plays a major role in the homeostasis of the iron metabolism. It regulates iron absorption and its release from the cells by blocking the action of ferroportin, which is the iron intracellular exporter from macrophages, hepatocytes and duodenal enterocytes. Evaluation of serum hepcidin in IBD patients may become a key element in the diagnosis and treatment of anemia in the near future. The quantifi cation of hepcidin has potential usefulness in diagnostic algorithms for differentiating between iron defi ciency anemia (IDA) and anemia in chronic diseases (ACD) and the combination IDA/ACD.

Abstract. Laryngeal squamous cell carcinoma (LSCC) is one of the most common cancers of the head and neck. LSCC is characterized by a high frequency in Bulgaria and Europe, 8.9/100 000 и 3.2/100 000, respectively. No change was observed in the survival, despite the introduction of modern approaches in treatment. It is therefore necessary to establish biomarkers that can be successfully applied in clinical and medical-biological practice for the diagnosis and therapy of patients with LSCC. Micro RNAs are small non-coding sequences that are actively involved in the regulation of cellular processes. Altered expression levels are commonly seen in cancers of the head and neck, including the LSCC, in both tissue samples and in samples of plasma, serum and saliva. It was found that micro RNAs may have oncogenic or tumor suppressor functions in the carcinogenesis of LSCC, which makes them attractive as molecular biomarkers. In this review we summarize current knowledge of the altered expression levels of micro RNAs in patients with LSCC and in malignant cell lines, and their potential as noninvasive biomarkers in clinical practice and their role in the processes of resistance to treatment.

Abstract. The literature review has an aim to summarize the knowledge, and therefore the requirement for introduction into clinical practice of modern immunological methods. Those should help to detect alterations in the macro-organism of patients suffering from circulating in our geographic region contagious infectious diseases. It is necessary to emphasize that the purpose is not to apply etiological methods. The second aim of our article is to apply in clinical practice innovative, reproducible and contemporary immunological laboratory tests using the mechanisms of health insurance. Those new methods should improve not only the diagnosis but also the appropriate administration of immunotherapeutic agents in the course of treatment. In the material are described, based on literature data, which investigations as a part of protocol (algorithm) could be useful for evaluation of alterations in the immune homeostasis of macro-organism in the course of the acute phase of the illness. In the discussion section, the authors discuss the optimal amount of immunoassays, which would satisfy the balance of benefi t and cost.
