Navalny's doctors prevented from seeing him at prison clinic

Navalny was transferred Sunday from a penal colony east of Moscow to a hospital unit at a prison in Vladimir, a city 180 kilometers (110 miles) east of the capital after his lawyers and associates said his condition has dramatically worsened.

In a post on his Instagram account, Navalny described a grueling search that lasted for several hours before his transfer and wryly described his condition.

“You would laugh if you see me now — a skeleton staggers around his cell,” the post read. "They can use me to scare children who refuse to eat: If you don''t eat porridge, you will be like that man with big ears, shaven head and hollow eyes.''”Navalny added a serious note that he was glad to hear from his lawyer about broad sympathy and support for him in Russia and abroad.

His lawyer, Vadim Kobzev, tweeted that Navalny so far has received only one glucose injection since Sunday at the hospital unit, which is intended to treat tuberculosis patients.

Six other attempts to give him a shot failed because paramedics apparently weren''t qualified enough to find his vein, he said. “His arms are all blue with the shots,” Kobzev said.

Reports about Navalny''s rapidly deteriorating health have drawn international outrage.

His personal physician, Dr. Anastasia Vasilyeva, led three other medical experts to try to visit Navalny at the prison clinic and the IK-3 prison in the city of Vladimir. They were denied entry after waiting for hours outside the gates.

“It''s a show of disrespect and mockery of the doctors,” Vasilyeva tweeted, adding that Navalny''s “life and health are clearly in danger.”Navalny, who is Russian President Vladimir Putin''s most adamant opponent, has been on a hunger strike since March 31 to protest the refusal by prison officials to let his doctors visit him and provide adequate treatment for back pains and numbness in his legs.

Russia''s penitentiary service insists that Navalny was getting all the medical help he needs.

Navalny was arrested in January upon his return from Germany, where he had spent five months convalescing from the Novichok nerve agent poisoning he blames on the Kremlin — an accusation Russian officials have rejected.

His arrest triggered the biggest protests seen across Russia in recent years. In February, a Moscow court ordered him to serve 2 1/2 years in prison on a 2014 embezzlement conviction that the European Court of Human Rights deemed to be “arbitrary and manifestly unreasonable.”The prison service said in a statement Monday that Navalny''s condition was deemed “satisfactory,” but another of his physicians, Dr. Yaroslav Ashikhmin, said over the weekend that test results provided by his family show Navalny has sharply elevated levels of potassium, which can bring on cardiac arrest, as well as heightened creatinine levels that indicate impaired kidney function.

Despite his worsening condition, Navalny still showed his sardonic humor.

“I laughed when I saw medical luminaries'' comments that with such a level of potassium that I had in my tests, I should have been either in emergency care or in a coffin,” he went on. “No, they wouldn''t get me that easily. I wouldn''t be scared with potassium after Novichok.”In response to Navalny''s deteriorating health, his associates have called for a nationwide rally Wednesday, the same day that Putin is scheduled to deliver his annual state of the nation address.

Russian authorities, meanwhile, have escalated their crackdown on Navalny''s allies and supporters, with the Moscow prosecutor''s office asking a court to brand Navalny''s Foundation for Fighting Corruption and his network of regional offices as extremist organisations.

Human rights activists say such a move would paralyze their activities and expose their members and donors to prison sentences of up to 10 years.
