FREEDOM'S TOLL

Infectious Diseases Rising Again in Russia

By ABIGAIL ZUGER

VORONEZH, Russia — Natalia Kostina lay flat on her back on a metal examining table in this city's tuberculosis hospital, staring impassively at the ceiling. In an instant, a doctor jabbed into her abdomen a thick needle attached to a syringe and pushed in a few cubic inches of air.

A moment later the needle was withdrawn and Ms. Kostina, silent and stoic, got off the table and returned to her room. Her treatment was over for another week.

Injecting air into the abdomen is a painful, archaic, last-ditch way to battle tuberculosis when medications are scarce or can no longer help. It has not been used in the West for decades.

But this is Russia, where TB, once nearly under control, has become epidemic since the collapse of the Soviet Union. Doctors often use air injections to fight TB strains that resist the most commonly used drugs. The technique compresses infected lungs, giving them time to rest and heal.

Ms. Kostina, 24, was healthy until two years ago, working as a nurse at the local prison, just a mile down the road from this hospital. There, as in most of Russia's overcrowded prisons, tuberculosis has been spiraling out of control. When she fell ill with fever and a cough, doctors quickly ascertained that she had caught tuberculosis from one of her inmate patients.

Despite months of treatment, her disease got worse. All four of the antituberculosis drugs she tried were powerless against it. Moreover, during the year she spent traveling from work to home, then into the hospital, then to a convalescent home, then back to the hospital, she had undoubtedly exposed dozens of others to her drug-resistant germs.

Russia's political turmoil, its economic crisis and its new freedoms have been accompanied by a wave of old diseases. Tuberculosis is flooding the country, producing what some authorities are calling the world's largest outbreak of the drug-resistant variety, one of medicine's most ominous problems.

Rates of other infections, including hepatitis, syphilis and AIDS, are skyrocketing. An epidemic of diphtheria swept through in the mid-1990's. Reports of smaller, regional outbreaks of encephalitis, typhoid fever, malaria, polio, pneumonia and influenza pepper the nightly news.

Health experts describe Russia's prison system as an "epidemiologic pump," continuously seeding the country with pockets of tuberculosis that can spread on their own. Increasingly, TB cases of Russian origin are turning up in the Baltic countries and even farther afield — for instance, Germany and Israel.

Specialists worry that if the rising rates of infectious diseases in Russia continue unabated, the country itself may turn into an epidemiologic pump, sending infectious diseases into the rest of the world.

"It's not surprising to see a case here," said Barry N. Kreiswirth, a tuberculosis expert at the Public Health Research Institute in New York City, "but it's a good reminder that it doesn't take much for one person to be a vector and start an epidemic."

An Old Scourge Made New

Tuberculosis is hardly new in Russia. It ravaged the country in the 19th century and the first half of the 20th. But before the Soviet Union fell it was finally being brought under control, through major government effort and expense. Infection rates, though roughly three times higher than in the United States, were falling in parallel with those in Europe and developed countries elsewhere.

This victory bred "a tremendous pride on the Russian side," said Dr. Mario Raviglione, coordinator for TB activities at the World Health Organization in Geneva.

That has changed.

With thin budgets, government health programs are no match for infections given new momentum by increasing poverty, stress, alcoholism, overcrowding and intravenous drug use.

Mortality from infectious diseases has not reached third world rates here. Last year, infections were estimated to account for 2 percent of all deaths.

But that is still four times higher than in most developed nations. "The total cost of infectious diseases in Russia is not that great," said Martin McKee, an expert in Russian public health at the London School of Hygiene and Tropical Medicine, "but the important thing is that it is going up and up and up." As AIDS becomes more firmly entrenched, that cost is expected to rise even faster. Deaths due to tuberculosis alone rose 30 percent in 1999.

In the days of the Soviet Union, the powerful Sanitation and Epidemiology Service, or "SanEp," sought out infectious diseases and stamped them out with compulsory vaccinations and annual disease screenings: chest X-rays for tuberculosis, blood tests for syphilis. People suspected of harboring infection were removed from society for as long as it took to guarantee that they were no longer contagious. The SanEp tactics were brutal — people were often taken from their families and hometowns for months to years — but they were effective.

"Now, instead, we have human rights," said Alla Loseva, the Voronezh tuberculosis hospital's deputy chief doctor, rolling her eyes. SanEp is but a poorly funded shell of its former self. Its job has fallen instead to doctors like Ms. Loseva, struggling to contain the epidemic with minuscule budgets and skeletal staffs.

A colleague, Dr. Galina Chervanova, said that when she arrived at the hospital in 1987, "there was even talk of eliminating TB completely."

"Now we are not even close to that anymore," added Dr. Chervanova, the hospital's deputy chief superintendent. "The number of sick people has risen, and we are seeing many, many difficult, chronic cases."

Prisons as Incubators

When it comes to TB, this faded industrial city 300 miles south of Moscow mirrors the nation. As elsewhere, the number of TB patients has almost doubled since 1993 — and the source of most of the local epidemic is the prison down the road.

After the Soviet Union collapsed, prison populations soared in Russia, which now shares with the United States the highest per capita rates of incarceration in the world. From overcrowding and weak health programs came breeding grounds for tuberculosis, which is transmitted by particles coughed or sneezed into crowded spaces.

Without a steady supply of the right medications, TB becomes resistant to drugs and much harder to treat. This was the case in the prisons, where anti-TB medications are continually running short, and prisoners still in need of treatments are released or transferred.

An epidemic-within-an-epidemic of drug-resistant disease soon arose and began percolating out of the prisons, carried by workers, like Ms. Kostina, or by released prisoners. Periodic prison amnesties also flooded the country with prison-bred TB — last year, Dr. Chernova said, more than 1,000 prisoners with active tuberculosis were released into the Voronezh area.

"In Russia at one point," said Dr. Paul E. Farmer, a TB authority, "80 percent of the index cases of drug- resistant disease in the community could be traced to the prisons." Dr. Farmer is a Harvard anthropologist and infectious disease physician.

As many as 10 percent of Russia's million prisoners now have active tuberculosis, Dr. Farmer and his colleagues estimated in a report issued last year by Harvard University and the Open Society Institute at the Soros Foundation. More than half of those cases are resistant to at least one anti-TB drug, and 20 percent to 30 percent of them are resistant to several.

The Cost of Drug Resistance

Treating drug-resistant tuberculosis is among the greatest of medical challenges. It requires expensive, "second-line" drugs, which must be taken for years instead of months, and which have many side effects.

Dr. Raviglione of the World Health Organization estimated that drugs to treat an ordinary case of TB in Russia would cost $20. But he put the bill for a drug-resistant case at $13,000.

In Voronezh, Ms. Kostina has been luckier than most. To supplement the painful weekly injections of air into her abdomen, which let her infected lung rest, doctors found her a last- ditch pair of medications: a spray she inhales directly into the lung, and expensive American pills imported by the Russian government and doled out in tiny quantities to outlying hospitals.

With this concoction of archaic and cutting-edge treatments, she has gotten better. Her fever is gone. She has gained weight, and the cavities in her lungs have shrunk. She left the hospital last September to convalesce at home. So far none of her family has come down with TB.

But the expensive pills she takes twice a day use up her hospital's entire allotment. As long as she needs the medication, the hospital has none for anyone else.

In the face of desperate medicine shortages, nearly a dozen private and public international health organizations are now collaborating with Russian experts to regain control of the disease.

Although they represent an international investment of hundreds of millions of dollars, these efforts involve only about a dozen of the country's 70 provinces, Dr. Raviglione said, reaching a "pretty small percentage" of the population.

Nor is it very clear how best to use the money. The W.H.O. prefers to treat TB with a carefully monitored combination of standard first-line drugs. But that method is at best ineffective in treating drug-resistant TB. At worst, it risks increasing levels of drug resistance.

Yet freer use of the longer-term drugs has perils, too.

"We are terribly afraid of liberal use of second-line drugs," Dr. Farmer said.

Some experts fear that without close monitoring, such an approach would breed a form of disease resistant even to those drugs and essentially untreatable.

Sex, Drugs and Disease

Further, an epidemic in one disease could easily ignite epidemics in others. Infection with H.I.V., the virus that causes AIDS, is rising faster in Russia than almost anywhere else, according to estimates from the Joint United Nations Program on H.I.V./AIDS. And syphilis and hepatitis B cases skyrocketed during the 1990's.

This is an explosive combination: syphilis enhances the sexual transmission of H.I.V., and tuberculosis can worsen the immune deficiency caused by H.I.V. An H.I.V. infection, in turn, can cause syphilis and tuberculosis to take unusual forms, making them both harder to diagnose and harder to treat.

The resulting cyclone of mutually enhancing infections can tax medical ingenuity and budgets everywhere. In New York City in the early 90's, for instance, an outbreak of tuberculosis among H.I.V.-infected people and their contacts — involving about 1,000 cases of drug-resistant disease — cost more than $1 billion to squelch, by some estimates.

In Russia, H.I.V. is largely confined to intravenous drug users. An estimated three million Russians use such drugs, with H.I.V. infection rates among them in some areas as high as 30 percent. Public health authorities know that H.I.V. will soon begin to spread among this population's sexual partners.

Pavel Ryabov, 21, works in a Moscow candy factory and has used intravenous drugs for the last two years.

He has hepatitis B and C, which are usually contracted through sharing needles with infected people, and he was admitted to a Moscow hospital over the summer with meningitis.

From his hospital bed, Mr. Ryabov expressed fear of AIDS, but said he nonetheless routinely shared needles with drug-using friends and did not use condoms with his two girlfriends.

"Yes, so maybe I'll stop using drugs," he said. "I've already begun to drink instead."

Risk of disease increases drastically, of course, where drugs and sex intersect. Recent studies have shown, for example, that in some groups of drug-using prostitutes here, H.I.V. infection rates have exceeded 50 percent. And prostitution, in turn, has been driven up by deepening levels of poverty.

Dr. Olga Loseva, chief of the venereal diseases department at the Central Research Institute for Skin and Venereal Diseases in Moscow, called sex "a new form of currency here."

"We really have had a sexual revolution here," she said. "People have earlier sexual relationships, more partners, more one-night stands, more children born out of wedlock."

In Soviet times, a system of screening and treatment, in combination with fines, unemployment and even imprisonment for some patients, kept syphilis and other venereal diseases in check.

While the punishments have been eliminated, the stigma of syphilis lingers. In Moscow and other cities where rates are particularly high, there are underground clinics that, for a price, guarantee anonymity. But they frequently fail to treat patients effectively and do not reliably keep track of the number of infections they see.

Thus, although figures over the last three years show a 30 percent drop in syphilis cases, public health authorities are skeptical.

"We're hopeful these figures really reflect a decrease in disease," said Dr. Caroline Ryan, associate director for international activities in the division of sexually transmitted disease prevention in the Centers for Disease Control and Prevention in Atlanta. But the decrease may merely reflect underdiagnosis or underreporting of cases, she said.

The worry is that the stigma factor may drive the young H.I.V. epidemic partly underground too, making it even more difficult to control.

Looming Infection

Here in Voronezh, as in most of Russia, these brewing infections seem invisible. Doctors say they have seen only a single case of AIDS, in an Ethiopian woman who got sick while visiting five years ago. Syphilis rates are low and stable, according to the city health commissioner, Dr. Michael V. Ivanov, and no cases of H.I.V. infection have surfaced.

But at the edge of the city, within the complex of infectious disease hospitals where pear and apricot trees separate the tuberculosis hospital from the region's largest infectious disease hospital for children, the doctors can hear the hoofbeats of trouble ahead.

The city's pediatricians are now seeing about 50 cases of congenital syphilis a year, a disease they only used to read about, said the hospital's pediatric epidemiologist, Dr. Emilia Bashenova.

And a steep increase in hepatitis B, which is far more contagious than H.I.V., has been ascribed to increasing intravenous drug use and sexual transmission of the infection.

Diphtheria cases soared nationwide in the early 90's, the combined result of declining childhood vaccination rates and the vulnerability of adults who had received shoddy Soviet vaccines as children. Since a new vaccination campaign backed by international aid, diphtheria is now rare again.

But the low numbers don't tell an accurate story, Dr. Bashenova said. "Even though numerically they are not up," she explained, "the cases of infections are more serious, and we see more complications from each. Immunity is down among our children here. It comes from poverty, from too little food, not enough vitamins, from more difficult access to health care — the children are sick more often, and more seriously sick."

This city lies halfway between Moscow and Chechnya, and already Chechen refugees have turned up with TB. Doctors have been alerted that cholera, polio and the plague from that region may soon start showing up as well.

Dr. Bashenova shook her head doubtfully. "We're prepared," she said.
