Snakebite not a cause for Chronic Kidney Disease, study reveals

Snakebite is not a cause of the Chronic Kidney Disease of Unknown Aetiology (CKDu) in Sri Lanka, a latest study reveals.Lead researcher of the project Prof. Anjana Silva of the Rajarata Medical Faculty told The Island: “We have so far investigated in depth how snakebite causes paralysis in humans, the effectiveness of anti- venom for treating these patients as well as affordable tests to detect snakebite at the bedside and other long-term effects of snakebite.”

Prof. Silva says there are still many things that the team is not clear about, relating to snakebite so they need to continue the studies in the long run not only to understand more about snakebite but also to make a real improvement in the treatment and prevention of this unfortunate, preventable health hazard

Chronic Interstitial Nephritis of Agricultural Communities (CINAC), also known as Chronic Kidney Disease of Unknown Etiology (CKDu), has been a major health issue in Sri Lanka, and has claimed many lives, especially in the North Central Province, and other agricultural areas.

Although the exact cause of this ‘mysterious’ disease has not been elucidated, several hypothesis, including a mix of possible causes, such as water, agricultural activities, agrochemicals, heavy metals, snakebite and heat stress, have been previously attributed by scientists.

A recent research study, by a team of researchers from the Faculty of Medicine and Allied Sciences of Rajarata University, published in a leading medical journal, Clinical Toxicology, revealed that snakebite is unlike to be a cause of CINAC or CKDu in Sri Lanka. This study was conducted as a part of the PhD study of Dr. Subodha Waiddyanatha, where she followed up 199 snakebite patients, four years after the snakebite, and 168 patients, one year after the snakebite.

“At the time of snakebite, we have collected all the information of these patients, including the data on their kidney function. We compared this data with their kidney function, one and four years after the snakebite, and found no evidence of any association of venomous snakebite, with reduced kidney function. We found that those patients who had kidney failure after the snakebite, completely recovered when we studied them one and four years later,” Dr. Waiddyanatha said.

She said that a small number of patients, who had reduced kidney function, at the follow up, had clearly identifiable other causes of poor kidney function, such as diabetes and hypertension. This means that a snakebite is unlikely to be a cause of CINAC or CKDu in Sri Lanka. “However, we still need to closely monitor a large number of patients who develop severe kidney failure, after snakebite, to clearly understand how many of them could have reduced renal functions in the long run,” Dr. Waiddyanatha added.

“This study was conducted as a part of ‘Anuradhapura Snakebite Cohort’, probably the largest snakebite research study in the world, that was started in 2012 by a team of researchers from the Rajarata Medical Faculty that included Prof. Sisira Siribaddana, Dr. Senaka Pilapitya and myself, in collaboration with one of the foremost snakebite researchers in the world, Professor Geoffrey Isbister from Newcastle University, Australia. South Asian Clinical Toxicology Research Collaboration was instrumental in providing logistics for the study”, she said.

GL: Proposed anti-terror laws will sound death knell for democracy

Published

Prof. Peiris

‘Media freedom will be in jeopardy’

Former Minister of Justice, Constitutional Affairs, National Integration and Foreign Affairs Prof. G. L. Peiris has warned that the proposed Protection of the State from Terrorism Act (PSTA) will deal a severe blow to civil liberties and democratic rights, particularly media freedom and the overall freedom of expression.

Addressing a press conference organised by the joint opposition alliance “Maha Jana Handa” (Voice of the People) in Colombo, Prof. Peiris said the proposed legislation at issue had been designed “not to protect people from terrorism but to protect the State.”

Prof. Peiris said that the proposed law would sound the death knell for the rights long enjoyed by citizens, with journalists and media institutions likely to be among those worst affected.

Prof. Peiris took exception to what he described as the generous use of the concept of “recklessness” in the draft, particularly in relation to the publication of statements and dissemination of material. He argued that recklessness was recognised in criminal jurisprudence as a state of mind distinct from intention and its scope was traditionally limited.

“In this draft, it becomes yet another lever for the expansion of liability well beyond the properly designated category of terrorist offences,” Prof. Peiris said, warning that the elasticity of the term could expose individuals to prosecution on tenuous grounds.

Prof. Peiris was particularly critical of a provision enabling a suspect already in judicial custody to be transferred to police custody on the basis of a detention order issued by the Defence Secretary.

According to the proposed laws such a transfer could be justified on the claim that the suspect had committed an offence prior to arrest of which police were previously unaware, he said.

“The desirable direction of movement is from police to judicial custody. Here, the movement is in the opposite direction,” Prof. Peiris said, cautioning that although the authority of a High Court Judge was envisaged, the pressures of an asserted security situation could render judicial oversight ineffective in practice.

Describing the draft as “a travesty rather than a palliative,” Prof. Peiris said the government had reneged on assurances that reform would address longstanding concerns about existing counter-terrorism legislation. Instead of removing objectionable features, he argued, the new bill introduced additional provisions not found in the current Prevention of Terrorism Act (PTA).

Among them is a clause empowering the Defence Secretary to designate “prohibited places”. That was a power not contained in the PTA but previously exercised, if at all, under separate legislation such as the Official Secrets Act of 1955. Entry into such designated places, as well as photographing, video recording, sketching or drawing them, would constitute an offence punishable by up to three years’ imprisonment or a fine of up to Rs. 3 million. Prof. Peiris said. Such provision would have a “particularly chilling effect” on journalists and media personnel, he noted.

The former minister and law professor also criticised the breadth of offences defined under the draft, noting that it sought to create 13 categories of acts carrying the label of terrorism. This, he said, blurred the critical distinction between ordinary criminal offences and acts of terrorism, which require “clear and unambiguous definition with no scope for elasticity of interpretation.”

He cited as examples offences such as serious damage to public property, robbery, extortion, theft, and interference with electronic or computerised systems—acts which, he argued, were already adequately covered under existing penal laws and did not necessarily amount to terrorism.

Ancillary offences, too, had been framed in sweeping terms, Prof. Peiris said. The draft legislation, dealing with acts ‘associated with terrorism,’ imposed liability on persons “concerned in” the commission of a terrorist offence. “This is a vague phrase and catch-all in nature.” he noted.

Similarly, under the subheading ‘Encouragement of Terrorism,’ with its reference to “indirect encouragement,” could potentially encompass a broad spectrum of protest activity, Prof. Peiris maintained, warning that the provision on “Dissemination of Terrorist Publications” could render liable any person who provides a service enabling others to access such material. “The whole range of mainstream and social media is indisputably in jeopardy,” Prof. Peiris said.

Former Minister Anura Priyadarshana Yapa and SLFP Chairman Nimal Siripala de Silva also addressed the media at the briefing.
