In Latin America, social security and public sectors represent the largest financiers and providers of health care. Many countries in the region have compulsory packages of basic health care benefits. As part of an effort to improve quality of care and access, several health technology assessment agencies, both governmental and academia, among a number of Latin American countries have been formally established in the past few years. Several Latin American countries have recently developed and published methodological guidelines in economic evaluation, indicating that there is a growing interest in evaluating health-related products, drugs, and technologies used by the population. Presentations on the health care system and the role of health technology assessment, pharmacoeconomics, and risk sharing policies, from the public sector perspective, in the Latin American countries Argentina, Brazil, Colombia, and Mexico were made at the 3rd Latin American ISPOR Conference held in Mexico City in 2011 and are discussed in this article. In conclusion, there is a clear need for Latin American countries to evaluate the value of new technologies that are being incorporated into their health care system. In addition, health technology assessment guidelines are important for their local needs in terms of regulation along with common country unions. In the future, the Latin American region needs to increase drug access along with implementing cost-containment measures to improve quality and health outcomes.

BACKGROUND In Colombia, HIV and AIDS constitute one of the major diseases of high cost to the health system, making necessary health risk management of patients with this disease through comprehensive health care programs with their respective evaluation of results. OBJECTIVE To evaluate the relative cost-effectiveness of a care program for patients with HIV/AIDS affiliated to a health insurer in Colombia, comparing their results in three Health care provider (HCP). METHODS The study population corresponded to a cohort of patients older than 18 years with HIV/AIDS and affiliated to a health insurer in Colombia during 2011 and 2012. A cost-effectiveness and cost-utility analysis of a health care program for this population was performed on the basis of a Markov model, in which quality-adjusted life-years (QALYs) and life-years gained were assessed. This analysis was conducted from the insurer perspective. The time horizon was life expectancy. A discount rate of 3% was applied. RESULTS Drugs accounted for 80.54% of care costs. The average annual cost of patients in health state 5 was 3 times higher than that of patients in state 1. HCP A compared with HCP B generated an additional 1.53 QALYs, with a rate of incremental cost-effectiveness of

2400 per QALY gained. HCP C showed a dominated behavior. The variables that most influence the uncertainty were the cost of HCP A in health state 5 (55.52%) and the cost of HCP B in state 3 (27.51%). CONCLUSIONS HCP A is a very cost-effective option considering a threshold of 1 time the per-capita gross domestic product.

Abstract Sterol compositions of the cold water ophiuroids Ophioplocus januarii and Ophionotus victoriae and of the tropical ophiuroids Ophiocoma echinata and Ophiocoma wendtii are reported. The four sterol mixtures contain Δ 5 mono- and di-unsaturated common 3β-hydroxy-sterols. Ophioplocus januarii and O. victoriae contain 24-methylcholesta-5,24(28)-dien-3β-ol and 24ζ-ethylcholesta-5,24(28)-dien-3β-ol in higher abundance than in O. echinata . These sterols were not found in O. wendtii . An interesting finding is the presence of Δ 5,24(28) -24- n -propylidenecholesterol in 7.6% in Ophionotus victoriae .

OBJECTIVE To assess the cost-effectiveness of prophylactic administration of Granulocyte Colony-Stimulating Factor (G-CSF) compared with no use of it, during the induction phase of chemotherapy in Adults with Acute Lymphoblastic Leukemia (ALL) in Colombia. METHODS A decision tree with a time horizon of 30 days was built under colombian health system perspective including only direct costs. The costs of procedures and medications were taken from official sources and an institution of national reference of oncology services. The safety and effectiveness data were taken from the literature and two Colombian cohorts with patients older than 15 years. The unit of outcome was the proportion of deaths avoided. RESULTS Base-case results on a clinical trial indicate that using factor is a dominant strategy. The variable that most impacted the outcome was the incidence of febrile neutropenia. Considering a threshold of

22.228 USD in 80% of cases using factor was cost effective. However, the use of factor is not cost-effective for the country for incidences of febrile neutropenia > 48%. It was not possible to establish cost-effectiveness of pegfilgrastim because no information was found. CONCLUSION As per Colombian data, the use of prophylactic factor under chemotherapeutic induction in adults with ALL, turns out to be not cost effective. The difference in the results suggests the need of a careful extrapolation of information from clinical trials (ideal world) for developing economic evaluations in Colombia.
