Introduction: The U.S. pharmaceutical industry is defined by the U.S. Census Bureau as “companies engaged in researching, developing, manufacturing and marketing of medicines and biological for human or veterinary use”. Besides its main role in improving human health, the US pharmaceutical industry represents one of the most critical, key decision makers’ lobbying prone and competitive sectors in the economy. The cost in the environment of very limited government price regulation remains one of the major problems fuelling aggregate health care cost inflation. Pharmaceuticals have created huge benefits for public health and economic productivity by the means of saving lives, increasing life expectancy, reducing illness related suffering, preventing surgeries and decreasing hospital stays. Purpose: The goal of this review paper is to show the present conditions and future trends of the pharmaceutical industry in the U.S. Methodology: This paper represents a thorough literature review of the multifaceted sources including: studies, books, peer reviewed journals, U.S. government sources (i.e. U.S. Census Bureau, U.S. Bureau of Economic Analysis, etc.). Discussion: In the thirty years pharmaceutical companies have consistently developed and launched new medicines, bringing hope to sick or – at risk patients. They also usually provide above the average financial returns for its shareholders. U.S. pharmaceutical companies had as their goal to discover blockbuster drugs. Blockbuster drugs are generally defined as drugs that solve medical problems common to hundreds of millions of people and, at the same time generate large sales increases and profits for the pharmaceutical companies. The main approach of these companies includes huge investments in research and development (R&D), innovation, marketing and sales. The trend analysis shows that for the most part the era of blockbuster drugs is nearing an end. Conclusion: Numerous blockbuster drugs will be coming off patent in the next few years, opening the way to generics and eliminating a major source of the industry’s profits. Still, there is plenty of room for improvement in the medications people take while there is no shortage of human suffering to alleviate. It is doubtful whether big pharmaceutical firms will be able to pursue these goals within the old model of developing exclusive new drugs that can be sold further in the future. In the past, medicines for the ailments that were never before addressed, like anti-cholesterol or anti-depression drugs were developed. Currently, and in the future, it is expected that only blockbuster modifications will be developed. This phenomenon is expected to create market saturation, which will significantly reduce profits. The business model that drove the major drug makers’ success is not working anymore. Pharmaceutical companies must create new ways and to bring new ideas. The survivors will be those that market strategies supported by innovative approaches and winning capabilities.

Introduction: Hypoxia is a basic stimulant in production of erythropoietin (EPO). The primary function of erythrocytes is the transport of oxygen to tissues. Erythropoietin stimulates erythropoiesis which leads to increased production of erythrocytes- their total mass. This increases the capacity of the blood to carry oxygen, reduces the hypoxic stimulus and provides a negative feedback of stopping EPO production. The aim of this study was to establish a quantitative relationship between the concentration of erythropoietin, hemoglobin and hematocrit in different values of renal insufficiency. Material and methods: The survey was conducted on 562 subjects divided into two groups: with and without renal insufficiency. EPO, hemoglobin, hematocrit, serum creatinine and additional parameters iron, vitamin B12, and folic acid were determined by using immunochemical and spectrophotometric methods and glomerular filtration rate (GFR) was calculated as well. Results: EPO values (median) grow to the first degree of renal insufficiency, as compared to EPO values of healthy subjects, this increase is statistically significant, p=0.002. With further deterioration of renal function the values of EPO between all pathological groups are decreasing, and this decrease is statistically significant between first and second degree of renal insufficiency (RI) p<0.001. In the group of healthy subjects EPO is correlated rho = -0.532, p <0.0005 with hematocrit. The correlations are negative and strong and can be predicted by regression line (EP0 = 41.375- Hct * .649; EPO = 61.41–Hb * 0.355). In the group of subjects with the first degree of renal insufficiency EPO is in correlation with hematocrit rho=-0.574, p<0, 0005. It is also correlated with hemoglobin rho=-0.580, p< 0.0005. The correlation is negative (EP0= 42.168- Hct * 0.678). In the group of subjects with the third degree of renal insufficiency EPO is in correlation with hemoglobin rho=0.257, p=0.028. The correlation is medium strong and positive. In the group of subjects with third and fourth degree of renal insufficiency EPO is not in correlation with hemoglobin and hematocrit p>0.05. Conclusion: Renal dysfunction, depending on the level of RI effects differently on the biosynthesis of EPO in a diseased kidney, and consequently it also has a different effect on biosynthesis of HB in bone marrow and its content in the blood.

Introduction: Regulatory T cells (Treg) play a central role in the immunopathogenesis of psoriasis. Immunoregulatory T cells (Tregs) are involved in important homeostatic mechanism for maintaining tolerance and preventing autoimmunity, and autoimmune diseases. The aim of this study was to examine the role of Tregs cells in the pathogenesis of psoriasis, and determine the range value for Treg cells (CD4+ CD25+) in the peripheral blood of patients with psoriasis compared to the severity of disease. Material and methods: The study included 51 patients diagnosed with psoriasis and 25 healthy individuals. Phenotype profile of peripheral blood lymphocytes was determined by flow cytometry, and assessment of severity of disease was determined on the basis of PASI score (e.g. Psoriasis Area and Severity Index). Results: Proportion of CD4+CD25+T cells in the control group was significantly higher than in the patients with psoriasis [6,4% ±(5,4-7,6) vs. 4,1% (3,1 -5,8)–Mann–Whitney U test, p <0.001]. In the present study we did not find a statistically significant correlation between the levels of CD4+CD25+cells, in patients with psoriasis, compared to the severity of disease–PASI. (i.e. Pearson correlation, r = 0.197, p = 0.194). Conclusion: The stratification of patients, according to the severity of the clinical course was not possible on the basis of Treg cells’ level. ROC curve analysis of the optimal cutoff (PASI=10) and the CD4+CD25+, which distinguishes between patients and healthy individuals was 5% of CD4+CD25+ of the total number of CD4+ lymphocytes with specificity of 69% and sensitivity of 84%.

Introduction: Anti GAD (antibodies on glutamic acid decarboxylase) and anti-IA2 antibodies (against tyrosine phosphatase), today, have their place and importance in diagnosis and prognosis of Type 1 diabetes. Huge number of patients with diabetes mellitus type 1 have these antibodies. Insulin antibodies are of critical importance in diagnosis of diabetes mellitus type 1 for pediatric population. Materials and methods: During 2014, the samples of 80 patients from Clinical Center University Sarajevo (CCUS) Pediatrics clinic’s, Endocrinology department were analyzed on anti-GAD and IA2 antibodies. The samples of serums of all patients were analyzed with ELISA tests using Anti GAD ELISA (IgG) kites from EUROIMMUN company. These are quantitative in vitro tests for human antibodies against decarboxylase of glutamine acid (GAD) and IA2, in serum or EDTA plasm. Results: During the period of one year, in CCUS’s Organizational unit, Institute for Clinical Immunology, 80 samples of patients with anti GAD and IA2 antibodies were analyzed. Out of total number of samples, 41 were male patients, or 51% and 39 female, or 49%. The youngest patient was born in 2012, and the oldest in 1993. Age average was represented by the patients born in 2001. Share of positive results for IA2 antibodies and GAD antibodies was 37% for IA2 antibodies, and 63% for GAD antibodies. Discussion: During an autoimmune – mediated Diabetes mellitus type 1 leads to T-cell mediated destruction of beta cells of pancreatic islets, reduced production of insulin and glucose metabolism. Studies have shown that these bodies are the most intense single marker for identifying persons with increased risk for diabetes development.

Summary Background: The production of erythrocytes is regulated by the hormone erythropoietin (EPO), which maintains the blood haemoglobin (Hb) levels constant under normal conditions. Human EPO is a glycoprotein hormone and its synthesis is controlled by the hypoxia-inducible transcription factor. The aim of this study was to establish EPO and Hb levels in patients with chronic kidney disease (CKD), as well as in control subjects, and to investigate the relationship between these parameters. Methods: This cross-sectional, observational study included 356 subjects with CKD divided into 4 subgroups according to their glomerular filtration rate (GFR). The control group consisted of 206 age and sex matched healthy subjects with GFR rate ≥90 mL/min/1.73 m2. EPO, Hb and serum creatinine levels were determined by using immunochemical and spectrophotometric methods. GFR was determined using the MDRD formula. Results: The CKD patients had significantly lower levels of haemoglobin (p<0.0005) and hematocrit (p<0.0005) compared to control group. Our results showed that Hb levels decreased, whereas serum creatinine increased with the increasing renal failure. The CKD patients in all four groups had significantly lower (p<0.0005) Hb levels, and significantly higher (p<0.0005) creatinine levels compared to the control group. The median EPO in group I and II were significantly higher (p=0.002; p=0.018), while median EPO in group III and IV were significantly lower (p=0.03; p=0.011) compared to the control group. Conclusions: In patients with CKD, GFR positively correlated with Hb and EPO, while the correlation between GFR and serum creatinine was negative.

Aim: The main aim of this research was to determine the influence of socioeconomic status and residence/living conditions on the status of oral health (e.g. health of mouth and teeth) in primary school students residing in Canton Central Bosnia. Methods: The study was designed as a cross-sectional study. Our research included two-phased stratified random sample of 804 participants. The quantitative research method and newly designed survey instrument were utilized in order to provide data on the oral health of the examined children. The alternate hypothesis foresaw that “there were significant statistical differences between the levels of incidence of dental caries in comparison to the incidence in children of different socioeconomic status. Results: The Chi square () of 22.814, degree of freedom (Df) = 8, coefficient of contingency of 0.163 and T-test (Stat) of–0.18334 showed that there were no significant statistical differences at p < 0.05 level between the primary school children from urban and rural areas. The obtained results showed that the caries indexes in elementary schools in Central Bosnia Canton were fairly uniform. Research showed that there were a difference in the attitudes towards a regular dental visits, which correlated with social-educational structure of the childrens’ families. Conclusion: According to the results, we can see that the socioeconomic status of patients had an effect on the occurrence of dental caries and oral hygiene in patients in relation to the rural and urban areas, because we can see that by the number of respondents, the greater unemployment of parents in both, rural and urban areas, caused a host of other factors, which were, either, directly or indirectly connected with the development of caries.
