The carambolo , a star-like fruit originating in Asia, could be causing severe damage to patients with kidney problems . To this conclusion came a study led by Professor Diego Rosselli, from the Department of Clinical Epimediology of the Pontificia Universidad Javeriana , and published in the Saudi Journal of Kidney Diseases.
This fruit, despite being harmless to most people, can generate neufrotóxicos and neurotoxic effects thanks to two components: the caramboxin acid or caramboxina, and the oxalic acid, which can develop problems in the kidneys and stimulate the main inhibitor of the system central nervous
This is why people who report carambol poisoning usually present symptoms such as hiccups, altered states of consciousness , vomiting, psychomotor agitation, epilepsy and even reaching a coma.
To reach this conclusion, Rosselli and his team analyzed the scientific literature that was available in three databases: PubMed, Litacs and Embase. In total, they found 26 articles that included 123 cases . In 99 of these, cautions the study, the carambolo intoxication was related to chronic renal failure while the remaining 20% (24 patients), three ended with chronic renal failure and two became dependent on dialysis.
“The highest risk is presented by people with terminal renal failure, those who are in dialysis programs, to whom this fruit should be prohibited. But there are many people, particularly diabetics or poorly controlled hypertensives who may have kidney failure without knowing that they could be at risk, “the researchers note in a statement.
As for the neurological effects that can cause a carambolo intoxication the study indicates the following: 36 of the 99 patients with renal failure cases presented confusion or speech inconsistent , 29 had seizures, 22 alterations of consciousness and 11 came to be in states comatose On the other hand, of the 24 cases that did not have a previous renal diagnosis, two had insomnia and only one presented confusion, seizures and altered state of consciousness. Of the 123 cases analyzed, in addition, 28 deaths were reported , that is, 22% of the sample.
The study was conducted with 47 cases in Brazil, 36 cases in Taiwan, 20 cases in Bangladesh, eight cases in China and France, two cases in Sri Lanka and only one case in Thailand and Colombia.
“The intoxication to consume carambolo, in spite of being relatively rare, is a global phenomenon. While the majority of cases apparently occur in Asia, where their production and consumption is higher, there are sporadic cases described around the world, “the study concludes.
“Given the growing popularity of this fruit it is vital to increase awareness among patients and doctors about the risks of its consumption. Patients with kidney failure or those at risk of developing should be the most warned about it. People with normal renal function, on the other hand, should avoid or at least limit the intake of the carambolo, since they could also be affected. “
