RESUMO

Inmunoglobulina G Endovenosa UNC is a 5% liquid Argentine intravenous immunoglobulin obtained from South American donors. This prospective trial was designed to evaluate if the product meets the minimal efficacy requirement of the US Food and Drug Administration of <1 serious infection/subject/year as well as its safety in pediatric patients with Primary Immunodeficiency Diseases. Thirty patients under the age of 18, with well-defined Primary Immunodeficiency Diseases received Inmunoglobulina G Endovenosa UNC (330-700 mg/kg every 3-4 weeks) for 6 months. Vital signs, laboratory abnormalities, adverse events and viral tests were assessed to evaluate safety. Two serious infections occurred (pneumonia and bacteriemia). The estimated infection rate was 0.114 serious infection/subject/year (95% CI, 0.003-0.2277). Minor adverse events occurred in 5.5% of infusions; fever and headache were the most common. Neither severe adverse events, nor abnormal laboratory values were observed. All viral assessments were negative. Inmunoglobulina G Endovenosa UNC meets the minimal efficacy requirement of the US Food and Drug Administration for pediatric Primary Immunodeficiency Diseases patients and showed efficacy and safety data comparable with other data published.

RESUMO

INTRODUCTION: Intravenous immunoglobulin (IVIG) therapy is an effective treatment in patients with different diseases. This product must comply with all the regulatory requirements established by the World Health Organization and the European Pharmacopoeia for clinical tolerance, therapeutic efficacy, and viral safety. Although IVIG are effective and safe products, in some patients they may cause adverse reactions. OBJECTIVES: The aim of this study was to assess the clinical tolerance of two pharmaceutical forms (lyophilized and liquid) of Imunoglobulina G Endovenosa UNC (IVIG UNC), a regional IVIG preparation, and to compare the reported data. PATIENTS AND METHODS: The pharmacovigilance reports of 149 infusions in 51 patients treated with lyophilized IVIG UNC and of 157 infusions in 53 patients treated with liquid IVIG UNC were statistically evaluated. Clinical tolerance was evaluated through the adverse reactions reported. RESULTS: Lyophilized IVIG UNC: adverse reactions were reported in 6.7 % of the total number of infusions. Of these reactions, 4.0 % were mild, 2.0 % were moderate, and 0.7 % severe. Liquid IVIG UNC: adverse reactions were reported in 3.2 % of the total number of infusions; of these, 1.3 % were mild, 1.9 % were moderate, and 0.0 % were severe. Statistical analysis showed no association between tolerance and the pharmaceutical form used (p > 0.05) and indicated similar tolerance for both preparations. CONCLUSIONS: Based on the results obtained, the excellent clinical tolerance of both pharmaceutical forms of IVIG UNC can be confirmed.

RESUMO

BACKGROUND: Intravenous immunoglobulin preparations are an effective therapy in several processes: primary and secondary immunodeficiencies, autoimmune and inflammatory disorders, infectious diseases and allergies, among others. This biological medicine must comply with three conditions: clinical tolerance, therapeutic efficacy and viral safety. OBJECTIVES: The aim of this study was to assess the therapeutic efficacy, clinical tolerance and viral safety of a regional intravenous immunoglobulin, manufactured by the Hemoderivatives Laboratory of the National University of Cordoba in Argentina (Inmunoglobulina G Endovenosa UNC), with plasma obtained from voluntary, unremunerated donors from Argentina, Chile and Uruguay. PATIENTS AND METHODS: The pharmacovigilance records of 448 infusions in 111 patients with different diseases were statistically evaluated. Clinical tolerance was evaluated by recording of adverse events, therapeutic efficacy was evaluated by taking into account the specific parameters of each disease, and viral safety was evaluated by analysis of serological markers of hepatitis B, hepatitis C and human immunodeficiency viruses before and after infusion. RESULTS: Adverse effects were observed in 4.6 % of total infusions, of which 3.1 % were mild, 1.3 were moderate and 0.2 % were severe. The therapeutic efficacy of the product was recorded in all diseases in which it was administered. Regarding viral safety, no seroconversions were registered in any of the records evaluated. CONCLUSIONS: The results of this study indicate that Inmunoglobulina G Endovenosa UNC is well tolerated, with good therapeutic efficacy and viral safety.

RESUMO

Immune thrombocytopenic purpura (ITP) is a bleeding disorder characterized by accelerated splenic removal of platelets opsonized with autoantibodies. Several different treatments have been tried in acute ITP patients, including intravenous immunoglobulin (IVIG) therapy. The aim of this paper was to assess the therapeutic efficacy, clinical tolerance and viral safety of Inmunoglobulina G Endovenosa-UNC, manufactured by Laboratorio de Hemoderivados, Cordoba National University, in the treatment of acute ITP patients. A prospective longitudinal study was carried out on 8 children, who were admitted to the Hospital de Niños de Córdoba, from July 1998 to June 1999. A dose of 1 g/Kg/day of Inmunoglobulina G Endovenosa-UNC was administered to those children whose platelet values remained < or = 20,000/mm3, 21 days after the first IVIG cycle. The observed results led us to conclude that Inmunoglobulina G Endovenosa-UNC is well tolerated and therapeutically effective in the treatment of acute ITP in children, with platelet values recovery, similar to those obtained with other IVIG. Moreover, it proved to be virally safe since the 8 patients were non reactive for viral markers of hepatitis B, hepatitis C and human immunodeficiency, 12 months after ending the treatment.

RESUMO

BACKGROUND AND OBJECTIVES: Intravenous immunoglobulin G (IVIG) preparations are used in several disorders: primary and secondary immunodeficiencies, autoimmune and systemic inflammatory diseases, and in infectious diseases as effective therapy. In this work, we report a method of processing IVIG (lyophilized and liquid) from Cohn fraction II (FII) paste. MATERIALS AND METHODS: The process included the following steps: virus inactivation by heat in a solution of FII, ultrafiltration, treatment at pH 4 with traces of pepsin, diafiltration and final formulation. Optimizations for each step on a small scale are described. The method has been effectively scaled-up. RESULTS: The final product contained at least 99% monomers plus dimers of IgG, a low anti-complementary activity (AcA) < 1 CH50/mg, and the remaining quality parameters fell within the range fixed by the European Pharmacopoeia. CONCLUSION: The method described is an effective way of preparing large quantities of IVIG (lyophilized and liquid) which fulfils the standard requirements of both the European Pharmacopoeia and the World Health Organization.

RESUMO

A survey was conducted among 110 Schools of Nursing in USA and 5 Schools in Latin America and the Caribbean (LAC) to identify the international health (IH) component in nursing education, practice and research. A significant part of U.S. schools and all 5 LAC schools have international activities, and this interest has started basically in the last 5 to 10 years. There was difference in the structure of IH activities among U.S. and LAC nursing schools, but they were similar in the type of support offered to IH initiatives. IH content in nursing education among U.S. schools was related to culture, health systems and community health; in LAC schools, IH content was related to health promotion, health policy and strategies and nursing perspectives. U.S. and LAC schools with international activities have only 10% of their faculty and students involved with IH initiatives. The nursing schools still lack courses and activities that the Schools of Public Health have implemented to deal with IH. The article observes areas that need to be strengthened so that nursing professionals can expand their leadership roles in research and practice in international health.

RESUMO

PURPOSE: To identify international health activities in United States, Latin American, and Caribbean schools of nursing. In the international community, nurses face challenges similar to those in related professions, but without the benefit of a long tradition. There is little research about how nursing education and associated activities prepare nurses to deal with international health, and little information about the extent of international health activities in U.S. schools of nursing. DESIGN: Descriptive. METHOD: Using a questionnaire with 16 items, a survey was conducted in 1995 on a random sample of representatives from 100 university schools of nursing in the United States plus 15 schools with known international activities (10 from the United States and 5 from Latin America and the Caribbean). FINDINGS: International health as a program topic was found in one-third of U.S. schools of nursing. However, nursing curriculums do not integrate international health with other subjects. Also, partnerships with foreign institutions are incipient and international health activities are usually individual initiatives with little institutional support. CONCLUSIONS: For nurses to become major contributors to international health, nursing curriculum content must shift from "international nursing" to "international health." Programs of nursing education should include study of social, economic, and political factors that affect health care systems. Schools should develop partnership agreements.

RESUMO

Trematodes found in the intestines of dogs from Chillan, VIII region of Chile, were studied. The species identified was Phagicola longa, a fluke of the Heterophyidae family, parasites of fish-eating birds or mammals in several countries. P. longa is very similar to P. arnaldoi, a species described in dogs from South America. The number of vitelline follicles and the distribution of cuticular spines are the only distinctive features for the two species. However, many authors report the same number of vitelline follicles for P. arnaldoi and P. longa. Furthermore, the distribution of cuticular spines is very similar. P. longa has a small area devoid of spines when compared to P. arnaldoi but a wide variability of this generic character in the Heterophyidae was observed. As previously reported, P. arnaldoi could be a recent synonym of P. longa, which is the only species of Phagicola that can be found in South American dogs. This is in agreement with the study of metacercariae found in Mugilidae, the intermediate hosts of Phagicola, from American waters in which P. longa is the only species found. The authors emphasize the finding of this trematode in dogs, since it could possibly cause also human infection.

RESUMO

Nursing in Latin America is facing a number of serious challenges significantly affecting the contributions its personnel con make to the health of the people they serve. This article presents an overview of nursing as an important component of the health system in Latin America through the prospective and orientation provided by strategic planning. The author, following an analysis of the nursing situation in the Region, identifies several problems and then creates a vision for the future. The article looks at the possibilities of developing and implementing projects and action plans to address the priority problems. It sees strategic thinking as a possible means for nursing to reflect on and maximize its contribution and presence in the solution of the health problems in the current decade and into the next century.
