Acta Medica Colombiana , 2007,
Abstract: in colombia, the official anti malaria treatments, falciparum and vivax, suddenly changed in october 2006. the objective of this work is to state the reasons why it is appropriate to maintain the above mentioned therapeutic schemes and to point out the problems that arise with the governmentês decision, as well as to suggest tasks for the immediate future. as of october 2006 the anti malaria falciparum treatment will be as follows: in the pacific coast, (chocó, valle, cauca, nari?o and the municipalities in antioquia, vigía del fuerte and murindó) the combination artemeter-lumefantrine will be given; in antioquia and córdoba the combination artesunate-mefloquine. malaria vivax shall be treated with chloroquine-primaquine, administering primaquine 0,60 mg/kg/day in seven days instead of 0,25 mg/kg/day in 14 days. the field assessments of the treatments in force until october 2006 showed the following efficacy levels: according to the who protocols, a) amodiaquine-sulphadoxine-pirimetamine for malaria falciparum 98%; cloroquine-primaquine 100% to cure acute attacks and 82% to prevent relapses. we do not know of any assessment carried out in colombia with the schemes. the worldwide experience with the adopted schemes is rather scarce and the efficiency is not better than the one found here for amodiaquine-sulfadoxine-pirimetamine. it is expected that the new treatments for malaria falciparum show efficacy levels of more than 90%, as well as the new malaria vivax scheme in cases of acute attacks but it is not expected to be the same or better for relapses. several immediate tasks are suggested to the health authorities.

Abstract: background: it is postulated that rh negative pregnant women have significantly less plasma cholinesterase activity than the rh positive, although others have not found this relationship. in addition, such association is not seen in non-pregnant women or in men. objective: to find the relationship among abo-rh blood groups and the levels of erythrocytes and plasma cholinesterase, in the general population according to gender as well as in pregnant women. methodology: descriptive, cross-sectional and prospective design. samples from adult working population (18-59 years) were taken, they had not been previously exposed to inhibiting cholinesterase pesticides (icp) and worked in companies affiliated to the social security, located in the valle de aburrá and the near east of antioquia, colombia. erythrocyte and plasma cholinesterase were measured by five different methods and the commercial serums were used to identify the phenotypes abo and rh. results: the smallest values of the erythrocytes enzyme always corresponded to group b - negative rh and the greatest values to group ab - positive rh. this regularity was not observed in the plasma enzyme, however, the erythrocytes, plasma and total blood enzymes did not show significant difference according to neither group abo or rh factor within any layer region-gender. in this study, all the pregnant women were positive rh and it was not possible to be evaluated the relation between cholinesterase and rh group in them. conclusion: a) we did not find any association between blood group abo and rh with any cholinesterase level in non-pregnant women, in men and in the general population. b) we could not assess the relationship between cholinesterase and rh in pregnant women.

Abstract: introduction: in latin america and colombia, there are few reports about links between malaria and nutritional status indicators. objective: to explore correlations between anthropometric and biochemical indicators of malnutrition. methodology: children (aged 4-11 years; residing either in el bagre or in turbo [antioquia, colombia]) participated in two different projects, with prospective, cross design. the first study worked with a sample of 100 children (aged 4-9 years), 51 with malaria and 49 without the disease. the second study evaluated 93 children (aged 4-10 years) with malaria. they received treatment, were cured, and reexamined after a 30-day period, already without malaria. two anthropometric indicators of long-term malnutrition (weight/age and height/age) were measured, as well as five visceral plasma proteins (albumin, prealbumin, apolipoprotein-a1, transferrin, ferritin), retinol, zinc, hemoglobin and c-reactive protein crp. results: significant “r” coefficients were weak (r <0600), generally positive: a) in the presence of malaria: cpr with hemoglobin (negative) and ferritin; hemoglobina-ferritina (negative); retinol with zinc and prealbumin; zinc with prealbumin and ferritin; apoa1 with albumin and transferrin, ferritin and prealbumin albumin; albumin and transferrin with zinc. b) in the absence of malaria: pcr with hemoglobin (negative), ferritin, retinol (negative) and apoa1 (negative); retinol with hemoglobin, zinc and prealbumin; zinc-prealbumin; apoa1-albúmina; prealbumin with albumin and transferrin. the only significant correlations between anthropometric and biochemical indicators were the following: a) height / age with transferrin (negative) in the presence of malaria and with apolipoproteína1 (negative) in the absence of malaria (both p <0.10), b) weight / age with apolipoprotena1: negative in the presence of malaria, positive in the absence of malaria (both p <0.05). conclusion: there were several significant correlations between biochemic

Abstract: antecedentes y problema: en 1998-2002 se investigó en antioquia (turbo, zaragoza y el bagre), la eficacia terapéutica de medicamentos y combinaciones antimaláricos. la interpretación de la respuesta terapéutica (adecuada, fallas precoz y tardía) requiere información adicional para una mejor comprensión. objetivo: definir un marco de referencia para interpretar los resultados de las evaluaciones de respuesta terapéutica antimalárica, constituido por información sobre el comportamiento de los programas antimaláricos en colombia y por información demográfica, epidemiológica, climatológica y socioeconómica sobre el departamento de antioquia, las regiones de urabá y bajo cauca y los municipios de turbo y el bagre. metodología: se usó información oficial secundaria y en menor cantidad, información primaria. con los datos recogidos se construyeron cuadros y gráficos, y se hicieron cálculos sobre otras variables. resultados: se describe la malaria (paludismo) en colombia en 1960-2002. en 2002, de los 43,707 millones de habitantes, 22,403 millones (51,17%) están expuestos (41,88% con bajo riesgo). el p. vivax es la especie predominante (66% de los casos), excepto en la región del pacífico, donde el p. falciparum causa el 75% de los casos. hay brotes de malaria cada 2 a 7 a?os; la más intensa epidemia en la historia conocida ocurrió en 1998. la mortalidad ha pasado de 25 por cien mil en 1983 a 3 por cien mil en 2000. el índice parasitario anual (ipa) ha estado alrededor de 8 por mil expuestos después de 1990, valor que es el cuádruple del existente en 1960-1970. la ineficacia del programa ha sido evidente casi desde su inicio en 1958 y la tendencia de la enfermedad siempre ha sido creciente. el fracaso de los programas gubernamentales antimalaria no tiene origen en fenómenos principalmente biológicos (resistencias del plasmodio a los medicamentos y del anofeles a los insecticidas), ni tampoco en las ''condiciones de orden público''. las principales responsables de la situació

Abstract: problem: in the past 5 years we have studied the treatment response to antimalarials and their combinations in the antioquia region (turbo, zaragoza and el bagre municipalities). the interpretation and better understanding of the treatment outcome (adequate clinical response, early treatment failure or late treatment failure) require further information since this response depends on host’s and parasite’s factors, independently of the characteristics of the antimalarial administered. objectives: to define an adequate reference frame which allows for interpretation of results obtained during antimalarials treatment assessment studies. this would include demography, epidemiology, climatic and social-economic information about colombia, antioquia, the regions of uraba, bajo cauca and the municipalities of turbo and el bagre. methodology: research of secondary information (publications reports and internet resources), and some primary information (taken from sistema de vigilancia epidemiológica de antioquia (sivigila) of dirección seccional de salud de antioquia dssa). data about treatment response were primary information (produced by grupo malaria, universidad de antioquia), or obtained from other authors. with the gathered data, tables and graphs were produced and calculations were carried out using other variables. results: the frequency of malaria is presented for colombia during the period 1960-2002 and the results of the malaria eradication and control programs, and their failure, are described. similarly, the frequency of malaria in antioquia during 1959- 2003 is discussed and presented in terms of incidence rates and parasite annual indexes (pai). non adjusted and adjusted rates and pai were obtained, therefore adjusted rates are presented by exposed population, which is less of 20%. adjusted results are 5-6 fold higher that non-adjusted values in antioquia. however this is not true for the uraba and bajo cauca regions, where 100% of the population is exposed t
La primaquina tiene alta eficacia en la quimioprofilaxis primaria simple antipalúdica: Metanálisis

Iatreia , 2006,
Abstract: background : there are many reportss about primaquine as primary chemoprophylactic (1-cp) in humans, but we do not know of any metaanalysis about this subject. specific questions : is primaquine effective to prevent malaria in humans? does primaquine efficacy to prevent malaria depend on the place, the age of patients, or the plasmodium species? methodology : procedures recommended for metanalysis were applied. results : four laboratory experimental studies (les) in humans and seven clinical controlled studies (ccs) were included. according to les the adequate primaquine dose as 1-cp for adults is 30 mg/day from the day before exposition and during the time of exposition. according to ccs protection was 93% in people that received primaquine and 45% in those who did not receive it (p = 0.0000000). conclusions : primaquine is highly effective for 1- cp of malaria, its efficacy is similar against both p. falciparum and p. vivax, it protects adults as well as children and 1-cp with primaquine must be adopted as a valid alternative. field studies are necessary in order to know the security and toxicity in children younger than eight years.

Abstract: introduction: worldwide, the efficacy of cloroquine-primaquine for treating acute plasmodium vivax malarious attacks has not been thoroughly evaluated. in latin america such studies are scarce, and in colombia, almost nonexisting. objective: to assess the efficacy of two regimens for administration of primaquine in children aged less than 18 years. methodology: a clinical, controlled, unmasked study was carried out, with randomized administration of two primaquine regimens, namely: 0.50 mg/kg/day for 7 days (0.50-7) vs. 1.17 mg/kg/day for 3 days (1.17-3). results: a. healing of the acute attack: efficacy was 100% in both groups. b. prevention of recurrences during 120 days: recurrences occurred in 68.4% of children treated with the 1.17-3 regimen, and in 34.2% of those receiving the 0.5-7 one. conclusions: 1. proportion of recurrences during the 120 days follow-up was significantly lower (34.2%) in children receiving the 0.50-7 regimen than in those treated with the 1.17-3 one (68.4%). the length ofadministration of the same total dose of primaquine influenced its efficacy against recurrences: shorter periods of administration were associated with lesser efficacy.
