Beyond Swollen Limbs, a Disease's Hidden Agony
By DONALD G. McNEIL Jr.
LÉOGÂNE, Haiti ? Like many surgeons, Dr. Yves Laurissaint is a man
supremely sure of himself.
"I've trained a lot of other surgeons to do this operation," he said as he
sliced open the engorged scrotum of 68-year-old Gesner Nicé, emptied more
than a pint of clear liquid, then began trimming away with a cauterizing
scalpel, filling the operating room with the acrid smell of burning skin.
"But they don't do it. They say it's too complicated."
Mr. Nicé, a woodcutter, has lymphatic filariasis, a disease in which
clusters of four-inch worms as fine as blond hairs nest in the lymph nodes,
the body's drainage system, stretching them until lymph fluid can only
To anyone who has visited poor tropical countries or seen pictures of the
disease, the instantly recognizable symptom, which afflicts both men and
women, is elephantiasis: legs so swollen that they resemble an elephant's.
But 10 times as common is the symptom that is almost never spoken of: the
engorged scrotums, known as male hydrocele (Greek for water bulge). In
cities like Léogâne, more than a quarter of the men are tormented by the
condition, their scrotum swelling to the size of a softball, or a
basketball in severe cases.
The operation that Mr. Nicé received will help alleviate his suffering. But
one great tragedy of lymphatic filariasis (pronounced lim-FAT-tick
fill-ahr-EYE-us-sis) is that it is not curable.
Still, it is one of a handful of diseases world health experts hope to
eliminate within a generation, because its spread can be prevented with
deworming drugs that can even be distributed in household salt, an approach
that wiped out the disease in China.
But the task is daunting, not merely because 120 million people in 80
countries have the worms, but also because of the stigma and secret shame
that the affliction causes, particularly in men, turning filariasis into a
disease the world hardly knows. Even where it is endemic ? 40 million
people suffer its symptoms in the world's most downtrodden places ? it is
cloaked in ignorance and misunderstanding.
"It's tied in with grinding poverty ? where you find it maps almost
perfectly with the poorest of the poor," said the Rev. Thomas G. Streit,
director of the University of Notre Dame's tropical disease program in
Léogâne. "And it's just heartbreaking."
Dr. Jaime Z. Galvez Tan, former chairman of the Global Alliance to
Eliminate Lymphatic Filariasis, a partnership of health agencies, donors
and drug companies, called it "the disease at the end of the road."
Imported from Africa with the slave trade, filariasis was long called
"Barbados leg" and found as far north as Charleston, S.C. It can disappear
spontaneously ? as it did in Barbados ? when countries prosper and the poor
are able to afford window screens to block the mosquitoes that transmit the
disease and local governments cover the sewers where they breed.
As common as filariasis remains, it is not easily contracted and is no
threat to tourists. Unlike malaria, which can be transmitted by a single
bite, it usually requires hundreds of bites from mosquitoes carrying male
and female worms, which must crawl into the puncture, find each other in
the victim's body and then mate.
In poor countries like Haiti and Guyana the disease hangs on. It does not
kill, but it crushes people's spirits and often leaves poor farmers unable
to work, which can mean starvation. The most pitiable can be spotted on
rural roads, shuffling slowly along in oversize pants.
In central Nigeria, Dr. John Umaru, a worm-disease expert for the Carter
Center, said he had seen a man "with a hydrocele down beyond his knee who
made a pouch and strapped it around his neck so he could carry it." He had
heard of another who needed a wheelbarrow.
"Some guys just go off in the bush and cut it open," he said. "They can't
live with it anymore. But then they often die of bleeding or infection."
In Mr. Nicé's case, his hydrocele, was about the size of a grapefruit, Dr.
Laurissaint said. He could not lie down comfortably, walking hurt and he
was embarrassed. "I can still climb coconut trees," Mr. Nicé boasted from
the operating table. (His hourlong operation was performed under local
anesthesia.) "And even if you see in me an old man, I can still perform
like a young man. I have nine children."
As for those with swollen legs, there is little relief. All they can do is
to wash their legs and feet daily to forestall infections as the skin
breaks and elevate them to relieve the swelling.
The limbs cannot be surgically drained because the lymph fluid swells all
the tissue instead of filling a pouch. The damage is permanent, because the
overstretched lymph nodes do not shrink again; the worms eventually just
die inside them.
For people with elephantiasis, big pants will not hide their affliction.
Funguses that erupt between toes stink and draw flies. Children can be
mocking. Lovers can be cruel.
Antoinette St. Fab, 30, sells rice and oil in an outdoor Léogâne market.
Both her legs are swollen, but the left is enormous, almost a foot thick.
"In the past, I used to carry things like spaghetti and canned milk on my
head and walk around selling them," she said. "But I can't do that
Because she now washes her legs frequently and smears antibiotic cream on
them, she rarely has the fevers of infected ulcers anymore. But the
pressure hurts, and she has trouble finding even flip-flops to wear. She
tries to hide her legs under ankle-length skirts, but she must slit them
very high to walk.
Her husband left her when he realized that her legs would not shrink, she
said. As her new boyfriend, a handsome out-of-work carpenter, sold goods
nearby, she said, "I don't know if he will leave me, too."
The other market women can be vicious. "I stepped on someone's foot by
accident, and she said, 'Hey, yam leg, don't put your fat foot on me.' I
told her: 'Oh, be quiet. God gave me this leg. Do you think that if I went
to the store to buy a leg, this is the one I'd choose?' "
Ms. St. Fab asked doctors to cut the leg off, but they refused, telling her
a disfigured limb was better than none. Even if they had, the swelling
could begin anew, higher up.
The worst known case was an Egyptian woman whose leg weighed 130 pounds,
more than the rest of her. It literally anchored her to the floor of her
Treating symptoms can be costly. Hydrocele operations run from $30 to $120
in different countries. A program to teach washing and disinfection
techniques costs about $17. But these steps do not aid in eradication,
which is complicated and costlier still, because it means treating millions
of people with deworming drugs every year, drugs that do not cure the
disease itself, but prevent its being passed on by killing the baby worms
that mosquitoes transmit.
Five years ago, the World Health Organization adopted eradication by 2020
as a goal, and progress toward it for the next five years will cost about
$1.5 billion, the Global Alliance said. But that estimate assumes that
billions of deworming pills will be donated by GlaxoSmithKline and Merck,
that technical advisers will be lent by the Centers for Disease Control and
Prevention in Atlanta and that American graduate students and local people
will work for no pay.
It also presumes continued financing from the biggest donors, including the
Bill & Melinda Gates Foundation, the World Health Organization and Unicef.
Even with money, eradication is tricky. When not placed in salt, deworming
drugs must be handed out yearly in remote villages. "Bush laboratories"
with microscopes and equipment to draw blood and track the effort must be
Adding to the challenge, some "night bleed" tests must be done after dark,
because baby worms swarm in the blood only then, when mosquitoes bite.
At Notre Dame's guest house here, all the window grilles have one extra bar
? twisted into the S-shape of the filarial worm. It is called Residence
Filariose. "If I get a donor who'll give a million dollars, I'll rename it
after him," Father Streit joked.
Léogâne, a coastal city of 150,000, has a perfect climate for the disease:
as a sugar-cane area, it is full of rum distilleries. Culex mosquitoes,
which carry the worms, lay their eggs in filthy water; the pools of cane
squeezings and sewage are ideal nurseries.
But ignorance also abets the disease's spread, for the embarrassment
filariasis causes does not lend itself to easy public discussion. During a
week in Haiti, a reporter was told by many people with filariasis that they
had swellings because they were kicked in a soccer game or by a horse, or
fell out of a tree or sat on a bewitched rock.
Ms. St. Fab said her mother, who also has elephantiasis, told her she got
it from jumping rope too much as a schoolgirl.
SeBien Diogi, 80, a local voodoo priest, said gwopye ? Creole for gros pied
or fat foot ? was caused by a white powder sprinkled on the ground, for
which he sells a brown-powder antidote. Other folk healers suggest leeches
and corn-mush poultices.
Even if infected people have a proper understanding of the disease, the
adult worms are frighteningly hardy, too big for deworming drugs to kill
and too deep in the body to remove surgically. Modern drugs aim to destroy
the baby worms, called microfilariae.
Several drugs ? all first developed for deworming cattle and pets ? will
kill the worms. They include Glaxo's albendazole, Merck's Mectizan (sold
under the name Heartgard for dogs) and diethylcarbamazine, which is made
cheaply by several companies, none of which donate as Glaxo and Merck do.
But they are now available in only a quarter of the villages in the world
where they are needed.
When he began working in Haiti in 1981, Dr. Patrick J. Lammie, co-director
of the C.D.C. effort to eliminate filariasis in the Americas, the treatment
was a 12-day course of diethylcarbamazine.
"We went house to house giving people a pill every day for 12 days," he
said. "It was a miserable experience." Even now, with one annual dose, the
task is gargantuan. Adult female worms breed for about six years before
they die, so every infected person in the world must be dewormed annually
for six years.
"Let's say you were trying to make rats extinct, but there was no such
thing as rat poison," explained Dr. Frank O. Richards Jr., a C.D.C.
parasitologist. "Instead, all you had was a form of once-a-year birth
control. You'd have to find a way to make sure that every single female rat
in the world got a dose every year until she reached menopause. Eventually
rats would die out ? but you see how hard the job is. If just a few rats
somewhere stayed untreated, it could bounce back."
Also, the drugs work better when taken together, which complicates
An alluring aspect, however, is that people like their side effects: they
kill other worms. Within days, mothers see their toddlers pass hookworms,
schoolboys with schistosomiasis stop urinating blood and adults see their
lice and scabies fall off.
"People feel a lot better," Dr. Richards said. "Mectizan is sometimes
called 'the poor man's Viagra.' People stop itching, they feel great, and ?
voila! I've heard of babies named Mectizan."
But a big annual dose makes everyone sick for a day or two, and in
dangerous countries like Haiti, pill-distribution days can draw gangs of
thugs. Officials would prefer a slower, gentler method: adding
diethylcarbamazine to household salt.
Thanks to several donors, Haiti has a salt program, but for a poor country,
it is relatively expensive. The program employs about 50 people to buy
local sea-salt brewed in beach pits, pick out rocks and twigs, wash it by
hand, spray it with diethylcarbamazine and iodine and then rebag it.
It costs 26 cents to make each bag of salt, said Jean Marc Brissau, manager
of the plant in Port-au-Prince. But it must be sold for at a loss, for 10
cents, to compete with the grimy local salt, or no one will buy it.
Getting people to accept treated salt can take time, but it is effective.
China eliminated the disease by ordering villagers to use it.
Despite the costs and the obstacles, Dr. Lammie and others, like Dr. Marie
Denise Milord, national director of Haiti's campaign against filariasis,
remain optimistic. Haiti hopes to wipe out the disease by 2012. "If the
world will keep helping," she said, "we will eliminate it."
