Scleroderma A
chronic manifestation of
progressive systemic sclerosis in which the skin is taut, firm, and
edematous, limiting movement. Localized patches of linear sclerosis of the
skin, mainly of the face and hands..
Scleroderma also affects the blood vessels and connective tissue of the
skin, lungs, and other internal organs, causing them to turn leathery and
hide-bound; losing elasticity. The symptoms are like rheumatoid
arthritis. It occurs most often in middle-aged women. Steroid drugs are
used in treatment, but there is no cure.
Sjogren's
Syndrome
Sjogren's syndrome and
hepatitis C virus. Ramos-Casals M, Garcia-Carrasco M, Cervera R, Font J
Systemic Autoimmune Diseases Unit, Hospital Clinic, Barcelona, Catalonia,
Spain. Sjogren's Syndrome (SS) is an autoimmune disease that mainly affects
exocrine glands and usually presents as a persistent dryness of the mouth
and eyes. The spectrum of the disease extends from an organ-specific
autoimmune disease to a systemic process. Viral infection has long been
suspected as a potential cause of SS because several viruses have been
incriminated in the aetiology of this disease, and a possible relationship
between SS and hepatitis C virus (HCV) was postulated in 1992. In this
paper, we review the literature concerning SS and HCV infection and
summarise the current knowledge regarding their association and their
pathogenic, clinical and immunological significances. The main conclusions
of this review are that the prevalence of antibodies to HCV in patients with
primary SS ranges between 14 and 19% using third-generation ELISA, chronic
HCV infection may mimic the main clinical, histological and immunologic
features of 'primary' SS and, finally, testing for HCV infection must be
performed in patients with SS, especially in those patients with evidence of
liver involvement or associated cryoglobulinaemia. HCV seems to be a rare
cause of 'primary' SS in the absence of recognised liver disease or
cryoglobulinaemia. Publication Types: Review
In Sjogren's syndrome,
changes occur in the immune system - the body's defense against disease. In
Sjogren's, the immune system lacks the usual controls. This causes white
blood cells to invade glands in the body that produce moisture, such as the
tear and salivary glands, and the Bartholins glands in the vagina. They can
destroy the glands and cause them to stop producing moisture.
Sjogren's syndrome can also cause problems in other parts of the body,
including the joints, lungs, muscles, kidneys, nerves, thyroid gland, liver,
pancreas, stomach, and brain.
In people with no other health problems, the most common early symptom is
the onset of severe dry mouth and eyes. In people with rheumatoid arthritis
or related conditions, dry eyes and mouth develop more slowly. In this case,
Sjogren's may be difficult to diagnose.
Sjogren's syndrome affects everyone differently. You may not have every
symptom listed here, and you may have only minor problems with those you do
have. The symptoms may seem worse at some times than at others.
Symptoms include:
Dry mouth: The mouth normally contains saliva, which aids chewing and
swallowing. In people with Sjogren's syndrome, the amount of saliva is much
less. This makes chewing, swallowing, and speaking difficult. It may also
cause a decreased sense of taste.
Dry eyes: Your eyes may feel dry, "gritty," or "sandy." They may burn and
look red. A thick substance may accumulate in the inner corner of your eyes
while you sleep. Your eyes may be more sensitive to sunlight.
If not properly treated, Sjogren's syndrome can lead to ulcers of the
cornea (the clear covering of the eyeball}. On rare occasions, this can
cause blindness.
Swollen salivary glands: There are three set of glands that produce
saliva. They're located under your tongue, in the cheeks in front of your
ears, and in the back of your mouth. They may feel swollen and tender. This
may occur along with a fever. This affects about one-half of people with the
disorder.
Dental cavities: This is a common problem that results from a dry mouth.
Saliva fights bacteria and defends against cavities. Because you have
decreased saliva, your teeth may develop cavities more easily.
Dry nose, throat, and lungs: This may make your throat feel dry and
tickly. You may have a dry cough, hoarseness, a decreased sense of smell,
and nosebleeds. It can also lead to pneumonia, bronchitis, and ear problems.
Dryness of the vagina: This can cause painful intercourse for women with
Sjogren's syndrome.
Fatigue is a common complaint. You may get easily exhausted and feel
tired and worn out.
Other problems: Sjogren's syndrome can affect other parts of the body,
such as blood vessels, the nervous system, muscles, skin, and other organs.
This can lead to muscle weakness, confusion and memory problems, dry skin,
and feelings of numbness and tingling.
Sjogren's syndrome can also affect the liver and pancreas. When it does,
there is a greater chance for developing cancer of the lymph tissue.
Although this is unusual, it is one reason why medical exams and continued
follow-up are important.
The causes of this condition are not known. There is some evidence that
viral infections, heredity, and hormones may in some way contribute to
Sjogren's syndrome.
Sjogren's syndrome can affect people of any race and any age. It usually
affects women. It affects more than one million people in the U.S.
Your doctor may do several things to find out if you have Sjogren's
syndrome. This includes:
Physical examination: Your doctor will ask you to describe your symptoms,
and will look for other symptoms, such as red, itchy eyes; swollen salivary
glands; a dry, cracked tongue; and enlarged lymph glands in your neck.
Blood tests: Tests for specific blood markers can determine if you have
Sjogren's syndrome. However, not everyone with Sjogren's has these markers.
Schirmer test: This helps determine how dry your eyes may be. It involves
placing a small piece of filter paper under the lower eyelid to measure the
amount of tears your eyes produce.
Slit-lamp examination: This is a more accurate way to find out if your
eyes are dry. In this test, the doctor puts a drop of dye into your eye and
examines the eye with a special instrument called a slit lamp. The dye will
stain dry or eroded areas of the eye. This test is often done by an
ophthalmologist (eye doctor}.
Lip biopsy: In this test, the doctor removes a few salivary glands from
inside your lip. The tissue is examined under a microscope. The appearance
of the tissue helps determine if you have Sjogren's syndrome.
Salivary function tests: These measure the actual amount of saliva you
produce, to help determine if you have Sjogren's.
Urine tests: These may be done to test your kidney function.
Chest x-ray: This can help detect changes in your lungs.
As yet, there is no cure for Sjogren's syndrome. But proper treatment can
help relieve symptoms so you can live a comfortable and productive life.
The main goal of treatment is to relieve discomfort and lessen the
effects of the dryness. Since Sjogren's syndrome affects everyone
differently, your treatment plan will be based on your specific needs.
Your treatment may include different ways to relieve your symptoms, such
as those listed below. If you have arthritis or another condition, you will
also want to follow specific treatment for that condition.
See your family doctor and your dentist regularly. Since Sjogren's
syndrome can affect many parts of the body, regular checkups can help detect
and prevent future problems. You may also need regular check ups with an
arthritis specialist) and an eye specialist.
For dry mouth:
* Sip fluids throughout the day.
* Use sugar-free gum or candies to stimulate saliva production.
* Try saliva substitutes or mouth coating products. They may be useful in
some people, and are available without a prescription.
To prevent dental cavities:
* Have frequent dental checkups.
* Use mouth rinses that contain fluoride.
* Brush and floss your teeth regularly.
* Use sugar-free products.
For dry eyes:
* Use artificial tears or eye drops to help relieve the discomfort of dry
eyes. Use preservative-free products, if you apply the drops more than four
times per day.
* Try lubricating ointments or small, long-acting pellets for overnight
or long-lasting relief.
* Your ophthalmologist may recommend a simple operation that blocks tear
drainage from your eye.
For dry skin:
* Use moisturizing lotions for sensitive skin.
* Avoid drafts from air conditioners, heaters, and radiators, when
possible.
* Use a humidifier in your house and at work.
For vaginal dryness:
* Use lubricants made specifically to help vaginal dryness. Do not use
petroleum jelly.
Medications
Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) help reduce
joint swelling and stiffness, as well as muscle aches.
If you have serious complications, your doctor may recommend stronger
medicines.
Exercise
Mild exercise, such as walking or swimming, can help keep joints and
muscles flexible. Exercise may also protect against further joint damage.
A note about pregnancy: A certain blood marker often found in women with
Sjogren's syndrome can, very rarely, be associated with heart problems in
newborn babies. If you're a woman with Sjogren's syndrome who is planning to
become pregnant, see your doctor about testing for this marker. If it is
present, ask your doctor whether pregnancy is advisable. If you do become
pregnant, you and your doctor can work out the best plan to manage the
situation.
Sjogren's syndrome is generally not life-threatening. The outlook for
people with this condition is usually good. Dryness, however, may last for
the rest of your life. By using artificial moisture and practicing good oral
hygiene, you can help prevent serious problems.
If you have Sjogren's syndrome and a rheumatic disease, make sure you
follow your doctor's complete treatment program.

Skin and Hepatitis C
Hepatitis C Virus–Related Skin
Diseases
Marie-Sylvie
Doutre, MD

THE HEPATITIS C virus (HCV) was identified 10 years ago thanks to
research in molecular biology.1
At present, HCV infection is a major public health problem in many
countries, with the worldwide prevalence of HCV markers ranging from
from 0.1% to 5% (including 150 million chronic carriers). Infection
becomes chronic in 70% to 80% of cases and is complicated by cirrhosis
within 20 years of contamination in about 20% of them. Once the
cirrhotic process has begun, the incidence of hepatocellular carcinoma
ranges from 1% to 4%. Factors leading to more severe liver injury
include excessive alcohol comsumption, older age at the time of initial
infection, immunosuppression, and specific genotypes. During the course
of HCV infection, many extrahepatic manifestations have been reported.2
IS THIS VIRUS CAPABLE OF INDUCING CUTANEOUS
DISEASES?
YES, CERTAINLY.

Hepatitis C viral infection is clearly involved in cases of mixed
cryoglobulinemia (MC) and porphyria cutanea tarda (PCT). Recent evidence
has incriminated HCV in many cases that, in the past, would have been
diagnosed as essential MC. This syndrome is characterized by palpable
purpura, arthralgias, and general weakness associated with cryoglobulins
composed of different immunoglobulins with a monoclonal component
(rheumatoid factor) in type II and polyclonal immunoglobulins in type
III.
Since the initial observations in 1990,3
several reports have described MC in about half of all patients with
chronic hepatitis.4-8
Patients with cryoglobulinema had cirrhosis more frequently and had a
longer history of hepatitis than those without.9
Similarly, 50% to 90% of patients with MC had anti-HCV antibodies and
liver dysfunction.
Affected patients often present with signs and symptoms of vasculitis
involving one or more organ systems. An increasing number of recent
reports suggest that cutaneous lesions are a major presenting feature in
some patients and even lead to the discovery of occult HCV infection.10
There is a correlation between the presence of palpable purpura, the
most frequent cutaneous lesion, and cryoglobulin levels. Several
findings confirm that HCV is the etiologic agent for MC and that the
virus may be involved in the pathogenesis of the vasculitis.10
Hepatitis C virus RNA sequences and HCV antibodies have been found in
sera and cryoprecipitates, more concentrated in cryoprecipitates than in
supernatants.11
By immunohistochemical or in situ hybridization methods, HCV has been
found in association with IgM and IgG in the cutaneous vasculitic
lesions of some patients.12-14
More often than not, type I interferons have proven effective in
treating cryoglobulinemia and improving the results of liver function
tests, which suggests a direct role for HCV in the development of MC.15,
16 On the other hand, in systemic
vasculitis, as in polyarteritis nodosa, HCV does not seem to play an
important role.17-19
A very strong association (50%-90%) between sporadic PCT and HCV
infection has been demonstrated in patients from the European
Mediterranean basin (Italy, Spain, and France),20-27
the United States,28
and Japan.29
In other countries (eg, Germany and New Zealand), the prevalence is low,
indicating that there is not significant association between HCV and
PCT.30,
31 Hepatitis C viral infection is
associated with an increased severity of liver histologic changes,
chronic hepatitis, and cirrhosis. Some cases of hepatocellular carcinoma
complicating PCT may also be linked to HCV infection.
Yes, Probably.
Lichen planus (LP) is possibly associated with HCV infections. In 1991,
LP was described in a patient with chronic hepatitis and HCV antibodies.32
Since then, numerous cases of LP associated with HCV infection have been
published. Several studies have been performed to gather information on
the prevalences of HCV infection in patients with LP. The reported
prevalence of HCV infection in patients with LP show wide variations,
from 3.8% in France33
to 62% in Japan,34
probably owing to the various techniques used to detect HCV: second- or
third-generation assays (enzyme-linked immunosorbent assays or
immunoblot assays) for the detection of anti-HCV antibodies and
polymerase chain reaction for the detection of HCV RNA. Account must
also be taken of the prevalence of the infection in a control population
from the same geographic region.
Yes, Perhaps.
Various skin diseases have also been described with HCV infection: acute
and chronic urticaria,35-37
pruritus and prurigo,38
and psoriasis.39
However, epidemiological studies are essential to determine the real
prevalence of these dermatoses in the course of HCV infection. The
prospective case-controlled study of Cribier et al40
in this issue of the ARCHIVES proves that at least in Europe, HCV rates
in chronic urticaria are similar to those of the general population.
HOW DOES THE VIRUS ACT?

In cryoglobulinemia, one possible mechanism is that antigen-antibody
complexes made of viral particles and anti-HCV antibodies might be
linked by IgM pentamers with rheumatoid factor activity directed at
anti-HCV antibodies. Immune complexes initiate activation of endothelial
cells, leading to altered vascular permeability, neutrophil
infiltration, and vessel wall damage. However, the presence of a
cryoglobulin does not necessarily result in vascular damage, which
depends on the presence of factors of the complement in the
cryoprecipitate, the physical and chemical characteristics of the
antigen-antibody complex, and probably on other local and/or circulatory
factors. An alternative mechanism was suggested by the findings of HCV
in vascular endothelial cells. Antibodies or T cells sensitized to HCV-containing
endothelial cells may initiate the process.
In PCT, HCV probably acts as a nonspecific factor that reveals the
enzymatic deficit of uroporphyrinogen decarboxylase in a genetically
determined terrain. The role of HCV in LP remains unclear: is it an
alteration of epidermal antigenicity? A replication of virus in skin and
mucosal lesions? This latter hypothesis is in fact unlikely, since
treatment with interferons more often than not results in the eruption
or aggravation of lesions.41
HOWEVER, WHY DO THESE SIGNS APPEAR ONLY IN
CERTAIN PATIENTS?

Viral, genetic, or environnemental factors may be reponsible for
cutaneous diseases associated with HCV infection only in some patients.
Several reasons have been proposed.
Viral Genotypes?
The distribution of HCV genotypes varies according to the region
studied. In most studies there is no predominance of any given genotype
compared with a control population devoid of any cutaneous
manifestation.42
In cryoglobulins, no predominance of a genotype has been noted except
in 2 Italian studies.43,
44 Three studies reported the
genotype distribution of HCV-infected patients with LP; this was similar
to that of patients with chronic hepatitis without LP.45-47
Viral Load?
Quantitation of viral load by reverse-transcription polymerase chain
reaction may offer a reliable marker of disease status. However, viral
load does not influence the occurrence of cutaneous signs in relation to
a cryoglobulin.
Genetic Predisposition of the Host?
Hepatitis C virus induces nonhepatic autoimmune manifestations only in
susceptible individuals, particularly those carrying the HLA A1, B8, DR3
haplotypes or the DR4 allotype.48
Recently, mutations in the HFE gene associated with hereditary
hemochromatosis (Cys 282 tyr, His 63 Asp) have been associated with
sporadic and familial PCT, suggesting that inheritance of
hemochromatosis alleles may be a susceptibility factor for the
development of the disease.49,
50 Hepatitis C viral infection
and these mutations might synergize to produce clinically manifest PCT.
Coinfections With Other Viruses?
Coinfection with hepatitis B virus and HCV is frequent in PCT.
Anti–hepatitis B virus and anti-HCV antibodies and/or hepatitis B virus
DNA and HCV RNA were simultaneously detected in the serum of about 30%
of patients.23-26
In patients with human immunodeficiency virus, both the human
immunodeficiency virus and the HCV are etiologic factors for PCT.
However, HCV probably plays the major role.
Hepatitis G virus is part of RNA virus, transmitted by the same route
as HCV. Some studies suggest that hepatitis G virus is not associated
with extrahepatic manifestations.40-51
When faced with leukocytoclasic vasculitis, a PCT, and probably a
lichen, especially an oral, erosive lichen, the physician must look for
a possible HCV infection. With other cutaneous diseases such as
psoriasis and prurigo, no systematic screening is possible without
further epidemiological studies, like that of Cribier et al40
with chronic urticaria.

Itching in Liver Disease
By Nora V. Bergasa, M. D.
Itching secondary to liver diseases, including primary
biliary cirrhosis, primary sclerosing cholangitis, and
hepatitis C, is a very difficult symptom for patients to
endure and for physicians to manage. The reason why patients
with liver disease itch is not known. It has been thought
that some substances accumulate in the blood as a result of
liver disease, causing itch.
Although the nature of the substance(s) that cause itch in
liver disease is not known, evidence has been accumulating
over the past several years to suggest that some substances
that are found normally in plasma known as endogenous
opioids (e.g. enkephalins), contribute, at least in part to
the itch secondary to liver disease. It has been proposed
that these neurotransmitters cause itch by acting on special
areas of the brain. Other substances that also accumulate in
the blood in liver disease, including bile acids, may also
play a role in this type of itch. There is no strong
evidence, however, to support that bile acids cause this
type of itch.
Traditionally, the way itch has been studied has been by
measuring the concentration of substances known to
accumulate in the blood of patients with liver disease who
itch. This method, however, has not advanced the
understanding of what causes this type of itch.
In order to conduct scientific investigation,
investigators have to apply reliable methods that allow for
the collection of information that can be analyzed and
interpreted in an objective way. The need for the
availability of good methods has been recognized for many
years by investigators in the field of itch. In this spirit,
an instrument was designed over ten years ago that allows
for the measurement of the human behavior that results from
feeling the sensation of itch: scratching. Several clinical
trials that use this method to record scratching have been
conducted. These studies have provided some insight into
itching and scratching, including the demonstration that
some patients scratch with a 24-hour rhythm, known as
circadian rhythm. This finding has suggested further that
the itch secondary to liver disease is mediated in the
brain.
At present there are several medications that are used
for the treatment of itch in liver disease. These
medications include cholestyramine, the antibiotic
rifampicin, the opiate antagonists naloxone and naltrexone,
and the serotonin type-3 receptor antagonist. These
medications appear to decrease itching in many patients, but
there is no medication that works well for all the patients.
This reality underscores the need to continue to look for
other medications that may relief the itch secondary to
liver disease.

THE FAMILY DOCTOR / Treating
Skin Blotches From Hepatitis Virus
Dr. Allen Douma
Q. My sister is 43 and has been suffering from
hepatitis C for some time. She has light-colored
blotches on her face and is ashamed to go out because it
looks so bad. - A.H., Far Rockaway
A. Hepatitis is inflammation of the liver. A
common cause is a viral infection, but toxic chemicals such
as alcohol can cause it as well.
Hepatitis C is a viral infection and is the most
common cause of liver disease except perhaps for alcoholism.
The hepatitis C infection is transmitted from an
infected person to an uninfected person. It is most commonly
transmitted by unsterile needles shared by intravenous drug
users.
Hospital and clinic workers can be infected by exposure
to the blood of infected patients. Transfusions with
infected fluids is another cause. Transmission by sexual
contact or from mother to fetus can also happen, but is not
very common.
Many people with acute (short-term) viral hepatitis
can recover within months, with or without treatment. In
fact, most of the time, medical treatment is unnecessary for
acute hepatitis, although hospitalization is
sometimes required. However, if the acute
hepatitis was caused by the hepatitis C
virus, there is a much greater chance of having significant
problems that may last for a long time.
Symptoms can begin with a general feeling of illness,
fatigue and poor appetite. A low fever and abdominal
discomfort may also be seen.
For acute hepatitis, bed rest is recommended as
needed. Interferon with ribavirin provides some benefit
about 50 percent of the time.
Within a month or so, a longer-acting form of interferon
should be available that decreases the number of shots
needed from three to one a week.
Both hepatitis and the drugs used to treat it have
been reported to cause light blotches of the skin called
vitiligo. However, vitiligo occurs more frequently in people
with thyroid problems, diabetes, pernicious anemia or
Addison's disease. This depigmentation of the skin can also
be secondary to atopic dermatitis, lupus and psoriasis.
Often no underlying cause is found. Although vitiligo may
be an indication of a serious underlying disease, its major
problem is that sometimes a person thinks he or she is
cosmetically disfigured, causing serious emotional
consequences.
If your sister's vitiligo is caused by her treatment of
hepatitis C, then stopping treatment may reverse the
condition, but it also may worsen her hepatitis.
Treatment of vitiligo has improved during the past
decade. Several treatments used more recently include:
light-sensitive drugs plus ultraviolet light (PUVA),
narrowband ultraviolet therapy (UVB), and local
corticosteroids plus ultraviolet light.
Often these treatments do not result in complete
repigmentation. Try one and, if it doesn't work well, try
another one.

Stroke
Magazine: Hepatitis Weekly, September 9, 1996 Section: Case Reports (HCV)
STROKES SEEN IN HEPATITIS PATIENTS WITH MIXED CRYOGLOBULINEMIA
---------------------------
Two cases of cerebral stroke
occurring in patients with hepatitis C virus infection and mixed
cryoglobulinemia are good arguments in favor of testing for these conditions
in patients with unexplained cerebral ischemias. Recent reports have
emphasized the association between HCV infection and mixed cryoglobulinemia.
Palpable purpura glomerulonephritis. arthralgias. and cutaneous and
peripheral nervous system vasculitis are the hallmarks of this disorder.
"Central nervous system (CNS) disease has been reported only rarely in
patients with mixed cryoglobulinemia from any cause. and no detailed
descriptions of intracranial vasculopathy and cerebral ischemia due to HCV
infection and mixed cryoglobulinemia are available." researcher George W.
Petty and colleagues wrote ("Cerebral Ischemia in Patients with HCV
Infection and Mixed Cryoglobulinemia." Mayo Clinic Proceedings. July
1996:71:671-678). "We describe two patients evaluated at our institution
with cerebral ischemia in the setting of HCV infection and mixed
cryoglobulemia." Patient 1, a 36-year old woman, was in otherwise good
health when left parietal cerebral infarction developed, and she was found
to have narrowing of the supraclinoid internal carotid artery siphon,
anterior cerebral artery A1. and middle cerebral artery M 1 segments
bilaterally. Subsequent evaluation revealed abnormal liver enzymes, mixed
cryoglobulinemia (type Ill), hypocomplementemia and a high positive test
result for rheumatoid factor. The second patient was a 35 year old woman who
was referred to Mayo Clinic Rochester because of headaches and seizures. She
had a history of nephritis (at age 12 years), treatment with glucocorticoids,
and subsequent development of avascular necrosis of both hips. When she was
31 years old, purpura caused by vasculitis developed, and she subsequently
had intermittent arthralgias. When she was 33 years old, type II mixed
cryoglobulinemia was diagnosed, and she was treated with prednisone. A
kidney biopsy specimen showed mesangial hypercellularity. Azathioprine was
added to the therapeutic regimen because of recurrent vasculitic skin
lesions. The researchers found that ischemic encephalopathy developed about
the time of treatment with plasmapheresis or institution of interferon alpha
(IFN-alpha) treatment (or both). Both women were found to have HCV infection
using polymerase chain reaction detection of hepatitis C virus RNA. "We
cannot comment on the efficacy of IFN-alpha in the treatment of CNS
involvement in patients with HCV infection and mixed cryoglobulinemia,"
George W. Petty and colleagues wrote. "Recombinant IFN-alpha has been shown
to be effective in controlling disease activity, as measured by
normalization of serum alanine aminotransferase levels and histologic
improvement on liver biopsy specimens in patients with chronic HCV
infection. "Both of our patients were treated with IFN-alpha. In one patient
(case 2), IFN-alpha had been used only for a brief period before cerebral
infarction developed. Whether her neurologic improvement was related to
treatment with prednisone only or whether she received some benefit from the
limited course of administration of IFN-alpha is speculative. The other
patient (case 1) had persistent changes of intracranial vasculopathy on
brain MR angiography after being treated with IFN-alpha for four months."
The authors conclude that cerebral ischemia may be the initial manifestation
of HCV infection and mixed cryoglobulinemia. "HCV serologic tests and
cryoglobulins should be considered in patients with cerebral ischemia of
inobvious cause, particularly in young patients and in those with abnormal
liver enzymes," they wrote. The corresponding author for this study is G.W.

Systemic Lupus
Erythematosus
WESTPORT,
CT (Reuters Health) Jan 05 - The prevalence of hepatitis C virus
(HCV) infection is higher in patients with systemic lupus
erythematosus (SLE) than in healthy control subjects, according
to a report published in the December issue of Arthritis and
Rheumatism. Also, the usual clinical manifestations of SLE are
different in patients infected with HCV, the authors state.
Dr. Josep
Font and colleagues from the University of Barcelona in Spain
studied the prevalence and clinical significance of HCV
infection in 134 consecutive SLE patients and 200 healthy
subjects.
The
authors found that HCV infection was present in 11% of SLE
patients and in 1% of healthy subjects. Compared with SLE
patients without infection, HCV-infected SLE patients had a
lower frequency of cutaneous manifestations and
anti-double-stranded DNA positivity. These infected patients,
however, had a higher frequency of hepatic involvement,
cryoglobulinemia, and low C4 and CH50 levels.
The
current study represents the largest series of SLE patients ever
analyzed for HCV infection, the researchers point out. The
findings also "suggest a possible link between HCV infection and
SLE."
Based on
their results, the investigators divided SLE patients with anti-HCV
antibodies into three groups: 1) Patients with a false-positive
result on the antibody assay; 2) Patients with HCV infection and
"true" SLE; and 3) Patients with a "lupus-like syndrome" that
may have been caused by HCV infection.
"We
suggest that HCV testing should be considered in the diagnosis
of SLE, especially in patients without" typical SLE
manifestations, the authors state. "Conversely, patients with
chronic HCV infection and extra-hepatic features mimicking SLE
should be tested for the presence of antinuclear antibodies and
anti-double-stranded DNA."

Involvement of the liver in SLE is a frequently misunderstood
complication of the disease. The liver can be affected as a result of lupus
itself, as well as the medications used to treat inflammation caused by
lupus. There is also a specific inflammatory disease of the liver, related
to SLE, called lupoid hepatitis. This column attempts to reconcile our
perceptions of what "lupus in the liver" really means.
Lupus can affect the liver in numerous ways that are delineated below:
- ENLARGEMENT OF THE LIVER, or hepatomegaly, is found in 10% of
SLE patients. The liver is rarely tender unless the enlargement is so
great that the capsule (or covering) of the organ is stretched. The most
common cause of large livers in lupus include lupoid hepatitis, congestive
heart failure, or cirrhosis.
- JAUNDICE, in which the person's skin has a yellowish hue, is
seen in 1-4% of patients with SLE. Manifested by high levels of bilirubin
which are responsible for this pigmentation, jaundice results from
autoimmune hemolytic anemia, viral hepatitis, cirrhosis, or bile duct
obstruction (from gallstones, tumor, or pancreatitis). Occasionally,
certain medications including nonsteroidal anti- inflammatory drugs and
azathioprine may produce jaundice.
- HEPATIC VASCULITIS, or inflammation of the small and medium
sized arteries of the liver, is extremely rare and is noted in one lupus
patient per thousand. It responds to corticosteroids.
- BUDD-CHIARI SYNDROME (which is very rare) results from a blood
clot in the portal veins which drain materials from the liver. Lupus
patients with the lupus anticoagulant, anticardiolipin antibody, or
antiphospholipid syndrome appear to be uniquely at risk for developing
these clots. Additionally, hepatic artery clots may occur. Untreated Budd-Chiari
can lead to ascites, portal hypertension, and liver failure. The preferred
treatment of Budd-Chiari syndrome is anticoagulation (blood thinning).
- ASCITES is a term which refers to fluid in the abdomen as a
result of the manufacture of this liquid by the peritoneum, or lining of
the abdominal cavity. Often associated with serositis (or similar fluid
being made by the pleura or pericardium which line the lung and heart),
ascites causes swelling of the abdomen and is noted in 10% of patients
with SLE. Usually reflecting active disease, it may be painless or painful
and can be mistaken for a "surgical abdomen" resulting in unnecessary
surgery. If an infection is ruled out, ascites is treated with
antiinflammatory medication, gentle diuresis, and occasionally periodic
drainage. Ascites also may result from liver failure or nephrotic
syndrome.
- ABNORMAL LIVER FUNCTION TESTS may be found in 30-60% of
patients with SLE. Blood enzyme evaluations included in routine blood
panels such as the AST (also called SGPT), ALT (also called SGOT),
alkaline phosphates and GGT may be slightly elevated as a result of a
variety of mechanisms. First of all, nearly all nonsteroidal
antiinflammatory agents, as well as aspirin, can elevate these enzymes,
and lupus patients appear to be particularly susceptible to this. These
minor abnormalities are usually of little consequence and I ignore them
unless they are greater than three times normal. Also, active lupus can
elevate these enzymes. Most nonsteroidals can be stopped for a week or two
and the enzymes rechecked. If they remain increased, the possibilities for
this elevation include hepatitis, infection, biliary disease, alcoholism,
or active lupus.
This leaves us with the most perplexing problem to discuss: lupoid
hepatitis. Described by Joske and King in 1955 and named by Mackay in 1956,
lupoid hepatitis has undergone many changes in definitions. The overwhelming
majority of patients who were told they had lupoid hepatitis between 1955
and 1975 would not fulfill current criteria for this disease. Initially
thought of as the presence of chronic active hepatitis (hepatitis means
inflammation of the liver) with LE cells, the term "autoimmune hepatitis"
seemed more appropriate since few of these patients had typical clinical
lupus. The development of diagnostic tests to detect hepatitis A, B, and
more recently C changed our concepts of lupoid hepatitis. The current
working definition of lupoid hepatitis is:
- liver pathology consistent with chronic active hepatitis
- absence of evidence for active hepatitis virus A, B or C infection
- a positive ANA or LE cell prep
Even using these criteria, only 10% of patients at the Mayo Clinic
fulfilled the American College of Rheumatology (ACR) criteria for SLE.
Although fevers, joint aches, malaise and loss of appetite are common (as
well as jaundice with itching), many of the physical findings we associate
with SLE (rashes, other organ involvement) are usually absent. This is
further complicated by the knowledge that lupus patients have compromised
immune systems and can develop a viral hepatitis, take liver-toxic
medications, and some abuse alcohol just as non-lupus patients do, which can
lead to chronic active hepatitis. Thirty to sixty percent of patients with
"autoimmune hepatitis", which is the term I prefer, also have antibodies to
smooth muscle or mitochondria (AMA or SMA)
Untreated, autoimmune hepatitis is fatal within five years. It can
respond to prednisone, steroids, alpha interferon, and azathioprine. Two of
our patients have undergone successful liver transplants. We have come a
long way in our understanding of liver disease in SLE and lupoid hepatitis,
but it still takes a great of skill to sort out what is autoimmune versus
viral versus medication related.
