My lab is certified
by CLIA and the College of American Pathologists for blood parasitology. I examine blood for bloodborne parasites:
Plasmodium (malaria), Babesia, Trypanosomes – flagellates, microfilaria. Today
I became aware of a bacterium which may appear in the blood but is not
bloodborne. Nocardia. I have a patient with this infection. I have been
treating her for a long time. We think Nocardia
infection it is chronic along with tickborne pathogens. The bacterium is found
in soil and water and is ubiquitous, there are numerous species, some not yet
speciated/characterized. We (the patient and me) have thought she suffers with
chronic nocardiosis. She has a clear,
documented history of Nocardia: positive pulmonary infiltrate and positive
blood culture. This is a slow growing organism. Texts say this rarely seen
organism cultures slowly, 3-5 days. Her culture was positive only after 28
days. Nocardia infections is thought to primarily occur in patients with impaired
immunity. She lacked clear evidence of immune dysfunction. The bacteria forms
lesions in the skin, lungs and brain. Generally, IV antibiotics are recommended
initially followed by oral therapy. Standard sources say skin infection is
always curable, lung infection is usually curable and brain infection is curable
half the time. Texts don’t address chronic nocardiosis, but I haven’t done a
literature search.
This
bacterium takes on an unusual appearance. We are accustomed to rods, cocci and spirochetes. Microscopically these appear as fungal-like
filamentous structures. The filaments
vary in length. Over the years I seen
similar things I thought they were contaminants or artifacts and most likely
were (not using the same stain). Perhaps
I missed something. Of course, this was
not on my radar. Images are startling. Images
of clumped filamentous structures, looking not like bacteria at all but rather the
dense threads seen with Morgellons appear. The images, if correct (I have not
validated them) can be found on google images. I know for a fact that some images
on google images are incorrect.
Then there
are patient images of skin lesions of the cutaneous form of the disease. Some look
horrible. Some clearly resemble lesions
seen with Morgellons.
The chest X rays
and brain MRIs are distinct from those seen with tickborne disease.
Again, this
organism is found on skin and in the lungs and brains. In severe cases it may also
appear in blood, gram stains. I don’t know if it also appears in Giemsa stains
I perform.
I wonder if
some cases of Morgellons are misdiagnosed nocardiosis. I wonder if Lyme immunosuppression
plays a role in the pathogenesis of the disease. Antibiotics recommended are some of the same
ones used for Lyme but not exactly the same ones. The initial early treatment
recommended is IV Bactrim.
Most readers
have some familiarity with the liver and gallbladder. The biliary (bile duct) system includes the
gallbladder and a collection of ducts coming from the liver which join to enter
the first part of the small intestines, the duodenum, the first part of the
small intestines (bowel) just below the stomach.
The liver is
best known as our body’s detoxification organ (along with kidneys). The liver “metabolizes,” alters
and excretes medicines and other substances.
The liver makes
bile, a yellow viscous fluid stored in the gallbladder, located directed under
the liver. The gallbladder contracts with meals. Bile made of bile acids, from cholesterol,
aid in the digestion of fat (an emulsifier) but has many other functions.
The liver
detoxifies medications and toxins through a system of enzymes with names like
cytokine P450. Toxins and medications may end up in bile.
Adsorption
of medications may be dependent on something called the enterohepatic
recirculation of bile.
Most bile is
recycled from the gut which is considered 95% efficient. A particular bile acid
molecule may be used 20 times before it is replaced. This is not necessarily a
bad thing. The process of repeated cycling may enhance the function of therapeutic drugs
and delay their excretion. For liver toxins this works the other way. Proper functioning of the enterohepatic
system depends in part on a healthy gut flora and specific bacterial enzymes. Higher doses of antibiotics may be required
because disruption of normal flora and necessary enzymes caused by the antibiotic(s).
The use of
bile acid sequestrants to remove unknown toxins like cholestyramine is not
supported by scientific evidence.
Some
antibiotics promote the production of biliary cholesterol sludge and gall
stones, primarily Rocephin, the popular intravenous drug used to treat Lyme
disease. Cholecystitis (gall bladder attacks) with or without the presence of gall stones is a common occurrence.
Lyme anecdotally can attack the biliary
system. Cases of positive Lyme PCR/DNA from gallbladder tissues are known to me but there are no published reports to date.
Published
reports have established Lyme liver disease in the form of granulomatous hepatitis.
Tests like
sonogram, HIDA/CCK scan and others may be used diagnostically for problems with
gallbladder and bile ducts. Negative
test results do not rule out gallbladder/biliary disease.
I am
treating a patient with primary biliary cholangitis (PBC). Generally, the disorder is
considered autoimmune, “idiopathic,” which of course means the patient is
pathological and the doctor is an idiot. Some European literature (this patient
is European) connects Lyme with this enigmatic illness. The patient has a clear
history of Lyme. No such connection is made in the U.S. PBC is now a treatable disease.
Bile via an
array of ducts ultimately empties into the common bile duct. Bile the empties
into the duodenum into a structure called the Ampulla of Vater. The flow of
bile is regulated by a muscle called the sphincter of Oddi.
After cholecystectomy,
(surgical removal of the gallbladder), prior gallbladder pain may seem to recur.
The bile ducts may become dilated. When a medical workup excludes a left-over stone
stuck in bile duct, liver disease, pancreatic disease and other rare diseases,
the diagnosis may be post-cholecystectomy syndrome or sphincter of Oddi dysfunction.
These
syndromes are more common in Lyme patients, many of whom suffer with
gallbladder disease and biliary tract disease and have had their gallbladders
removed.
The diagnosis
is commonly missed or not taken seriously. The disorder can be disabling. Effective
medical therapy, in my recent experience, is available but overlooked.
