(II) Homage to Dr. Clodomiro Picado. 45th years of the Clodomiro Picado Institute.

2nd PART:
ConCiencia
45th years of the Clodomiro Picado Institute

Before starting, let me give some data about Costa Rica as it will help to understand more the dialogue between the presenter and Dr. Jose Mª Gutierrez. 
Costa Rica (Rich Coast) has a total are of 51.100 Km2 and according to the 2011 census a population of around 4.5 million people!!!, half of them living in the capital of the country, San José. 

They are very advanced in green measures, sustainability and community medicine. 

I've been looking at the census done in 1927, a year after Dr. Clodomiro Picado promote the regulation against snakebites. 



These are the figures:
Total Population: 471.524 habitants. (Urban population: 88.608 habitants, Rural popularion: 382.916 (81.2%)

P: Chema, what was the situation related to snakebite in those times. Was it really necessary to set a program to face those problems?

DrJMG: Yes, in fact it was an important Community Health problem as it was in all the Latin American region. The statistical data in those times were not very clear but the estimated numbers were about five hundred, six hundred snakebite accidents… (seems quite small but related to the total population of the country it is a considerable number of accidents)

P: per year…

DrJMG: Per year, in the country

P: Oh, that is a lot, of course…

DrJMG: In fact, when the minister Aguilar Peralta decided to politically support this project, there is a moment where an ex-director of the Butantan Institute in brought to the country to make an evaluation of the problem itself and also to assess if it was really necessary to develop the snake anti-venom here, at local level, and the adviser conclusions where it was really necessary, that there was an important problem and also that the country was meeting all the scientific and technological requirements to move forward with this project.

P: Nowadays, what is the number of snakebites?

DrJMG: It is similar, is very interesting, same figures, the absolute number continues to be between five and six hundred snakebites…

P: but now the population is bigger than before…

DrJMG: Yes, if we talk in terms of incidence, then the incidence was bigger (see figures at the end 1927 census compared to 2011) and furthermore, the health resources were not so available as today, making the delay time to treatment for this people much bigger and sequels were also more severe as a result of it.

It is important to see that the privileged situation that Costa Rica has in relation to snakebites is not only due to the “Instituto” and the University of Costa Rica but that it was a “Country Project” so to say, because the foundation of the “Instituto” on the 1970 and the trespassing to the University on 1972 concurs with the fantastic development that the Community Medicine had as a national project in that period: the universalization of health services, the foundation of hospitals, the training of professionals in all Health specialities basically done by the University of Costa Rica, the targeted training of those persons on the topic of snakebites, the knowledge that through outreach programs like this one and other kind of activities about the topic… due to all of this, when somebody is bitten by a snake in Costa Rica, as fast as possible this person goes to a hospital or health centre, which is relatively close to the place were the bite happened, where the snake anti-venom is available and where there is skilled staff to treat the bite accident. So, there are all this factors plus the research and other related activities what allows the country to have a worldwide leader position on snakebite topic.

P: Let us talk about this diversification of the research… what other contributions have been done by the Instituto Clodomiro Picado to the research in our country and obviously internationally.

DrJMG: The philosophy of the “Instituto” has been always that to solve a problem, like in this case snakebite, it is necessary to know it, and this is a philosophy that comes from Clodomiro Picado and to know it, it is necessary to develop basic research, applied research, technological research etc. then, always the “Instituto” from the beginning and thanks to the clear sight of Dr. Róger Bolaños that triggered the project, has focused many of his activities on basic research: in short, what are snake venoms from the biochemical point of view, how do they act on the body, which are the mechanism of action… and from this knowledge, besides of being of scientific interest that generates a cultural heritage for the country, generates also ideas and concepts that enable us to improve the snake anti-venoms use for the treatment then… there is a direct line going from basic research passing through applied research, technological investigation, all of it in deep interrelationship  inside the “Instituto” to generate knowledge and the application of that knowledge to solve the problem.

The “Instituto” has always work as a collective, isn’t it?
It is a place where there is a team of people, nowadays we are seventy (she and he) work colleagues that function in unison, each of us in our workplace, each of us fulfilling his duty and at the same time, sharing a collective perspective view where there are many communicating vessels between sections, lots of dialogue, lots of reciprocal support on different things, and all of this allows this collective project to have a very enhanced capability to tackle a problem.

P: You have others elements obviously important as it is academic teaching and social action… and manufacturing, we should not forget that…

DrJMG: Yes, manufacturing is a component of the “Instituto” from the beginning, in fact the “Instituto” started as a manufacturing centre. The other activities where added afterwards. Manufacturing numbers have been rising, at the beginning about 10.000 vials of snake anti-venom were produced per year, enough to provide for Costa Rica requirements and later on we started providing anti-venom for all Central America region, about 60.000 vials, and at present more than 100.000 vials of snake anti-venom are manufactured per year, which allows us to help solving the snakebite problem in Colombia, in Ecuador, currently in Peru… as well as in very far away places like Nigeria, Mali, Burkina Faso, Papua New Guinea and we are starting a project in Sri Lanka (see previous post on Hypnale hypnale!), then… the production has developed a lot, due to the huge professionalism and capability of the production colleagues (she and he) and also due to the inputs coming from research to improve and innovate on the manufacturing process.

P: Do you know, approximately, how many persons have been benefited from the anti-venom?

Echi-Tab anti-venom for Nigeria developed at ICP
DrJMG:  Well, this is difficult to calculate but… let us say that in Costa Rica there are five hundred accidents multiplied by forty-five years… here we could have an idea. I would like to say something, and this about a project where I’m personally involved… since some years we are distributing anti-venom for Nigeria, the anti-venom produced for Nigeria is so effective that the doctors in Nigeria told us that a single vial, of 10 ml of anti-venom, is enough to treat a snakebite patient. For example, recently we exported a batch of 2.200 vials to Nigeria, week before last week, that means that there, the life of 2.200 persons will be saved… from a batch that reaches such a distant place. This gives an idea of the social projection of the “Instituto” at national and global level, isn’t it?

P: Academic teaching and social action… do you have students there… learning from all of you…

DrJMG: Exactly, all the investigators at the “Instituto” are teaching at the University of Costa Rica, many at the Faculty of Microbiology and other in other schools and faculties. The undergraduate teachings are of course given at the faculty and we also have a very important program for graduates, and we also received undergraduate and graduate students for the thesis and PhD works. I would like to say as acknowledgement and homage, that many of the academic developments of the “Instituto” had been developed by their students, that carried out PhD studies of a very good level, guided by the investigators (she and he) of the “Instituto”, contributing in these way to this collective creation that is the Instituto Clodomiro Picado.

to social action, I would like to say that the major component of the social action are the snake anti-venoms by themselves, is there any better social action that saving the life of a human being?... 


but we also have an element of continuous education based on activities like the prevention of the snake accidents in several communities in our country and outside our country too and for specific vulnerable population. We have also a very important element which is directed to specialized training of the health professionals to treat this pathology through symposia, hospital activities, visiting health centers etc.

P: Could we say Chema, that there is an area where do we have a higher incidence of snakebite accidents in Costa Rica?

DrJMG: Yes, this is quite well studied and relates to the regions common habitat for the “serpiente terciopelo” (Velvet snake - Bothrops Asper). The more vulnerable region is the South Pacific and also Caribbean regions and some in Central Pacific.
"Serpiente Terciopelo" Velvet snake Pit Viper - (Bothrops Asper)

P: All the cases related to “terciopelo” …

DrJMG: Most of the cases related to “terciopelo”, that is a very common snake on that regions. At the same time, those are regions where the poverty index in very high so, there is an overlap between the snakebite and poverty. In fact, researchers for other latitudes qualify snakebites as a poverty disease 
(Snake envenoming: A Disease of Poverty. R.A. Harrison et at. PLOS, Dec. 22 2009) 
and this is an element that invites too to the involvement of social science researchers to try to understand this relationship between poverty, environmental conditions and this health issue.

P: Snakebite from “terciopelo” is the most frequent… in second place… what do we have?
Tamagá. (Porthidium nasutum)



DrJMG: Very Very left behind, and this is not very well known because sometimes the people do not identify properly which is the snake responsible for the bite… it could the “tamagá”, it could be the “bocaracá” … but very far away from all of them is the “terciopelo”, in all Central America and part of South America.

Third part of the program the interview continues with Dr. Alberto Alape Jirón, the actual director of the Instituto Clodomiro Picado and also investigator and professor of the Faculty of Microbiology, University of Costa Rica. Next post!










Playing with numbers:I'm taking 550 snakebites/year (between 500 and 600)

Data about mortality. Found this nice article. Clearly mortality decreases after 1970, after the foundation of the Instituto and the local anti-venom started being produced. Also very important, the access to hospitals improved notably after 1980.

Snakebite mortality in Costa Rica.


Abstract

The mortality rate due to snakebite envenomation in Costa Rica was estimated from 1952 to 1993. The highest mortality was observed during the 1950s and 1960s, with the highest rate of 4.83 per 100,000 population in 1953. In contrast, a rate of 0.2 per 100,000 population per year was estimated from 1990 to 1993. The most conspicuous decline in mortality occurred after 1970. The highest mortality rates were observed in the provinces of Limón and Puntarenas, especially in regions where tropical rain forests had been transformed into agricultural fields. The lowest mortality was in the province of Guanacaste, where tropical dry forest predominates and Bothrops asper (terciopelo), the most important poisonous snake in the country, is not abundant. The majority of fatalities occurred in the age groups from 10 to 19 years old. Males were more affected than females in a ratio of 3.6:1. Before 1980 most fatal cases did not receive medical attention in hospitals, whereas after 1980 the majority of cases with fatal outcome were attended in hospitals.
