Weakness Experience by Most Acute Porphyrics

Most all acute porphyria patients experience muscle weakness from time to time and especially during and immediately following an acute attack of porphyria.

Muscle weakness or a lack of strength is a reduction in the strength of one or more muscles.

Such weakness in porphyria is a very important symptom.

The feeling of weakness may be subjective.

"Subjective" means that the person feels weak but has no measurable loss of strength or "concrete evidence" which is defined as a measurable loss of strength.

Weakness may be generalized or defined as a total body weakness. Weakness may also be localized to a specific area such as a limb, one side of the body, a side of the head, and such.

A subjective feeling of weakness usually is generalized and associated with infectious diseases such as infectious mononucleosis and influenza.

Weakness is particularly important when it occurs in only one area of the body. Such a weakness is considered a localized or focal weakness.

Localized weakness may follow an acute attack of porphyria. Often such weakness is found in conjunction peripheral nerve problems.

The common cause of such muscle weakness may result from a variety of conditions including metabolic, neurologic, and toxic disorders. This includes most of the porphyrias.

The toxic triggering of muscle weakness has been found to be largely in part due to pesticides, fungicides, herbicides, rodenticides, and paint and other chemical inhalations.

In most porphyria patients such weakness results in periodic paralysis which is potassium related, such as hypokalemic periodic paralysis which occurs when the potassium blood serum levels diminish.

Also other medical conditions by porphyria patients especially autoimmune disorders that interfere with the transmission of nerve impulses to muscle.

Porphyria patients that use chloroquine will also experience extreme muscle weakness. and while used to treat one form of porphyria the use of chloroquine by the other seven main forms of porphyria is contraindicated.

There may be other causes of weakness. This list is not all inclusive, and the causes are not presented in order of likelihood. . Furthermore, the muscle weakness may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as location, quality, time course, aggravating factors, relieving factors, and associated complaints.

Insurance Coverage for Porphyria Testing & Treatment

Disorders of porphyrin metabolism are now widely accepted by the medical community and coding is firmly establish .

The "porphyrinurias" have been listed by the International Classification of Diseases since 1920 (currently ICD 277.1).

The diagnostic need for detailed biochemical testing has been well established in the medical literature (urine and/or stool testing alone are insufficient).

Also among medical insurance providers there is broad agreement that the primary focus of treatment in acute cases must be on the avoidance of exposures that may trigger an attack. A few people are having problems with getting cocerage for home infusion, but the majority are having full coverage. [In some states home infusion is considered home care and unless you are HOMEBOUND you can not receive coverage.

It is recommended by medical insurance providers that if this is your case that you have your PCP contact their office and ask for the specific "CASE MANAGEMENT" which will allow for home infusion without being home bound.

Since so many types of porphyria have such potentially serious consequences, there is no excuse for denying complete and prompt evaluation in any suspected case.

If a person has bills where the coverage has been denied the majority of today's hospital and major clinic have Patient Representatives which will help patients get proper medical coding and insurance coverage.

Brain Fog is considered a Cognitive Disturbance.

Acute porphyria patients often describe their ability to focus and remember or function as being in a "brain fog". Such "brain fog" is actually known as a cognitive disturbance.

Cognitive disturbances involve a difficulty in basic mental operations such as memory, paying attention or focusing attention on something, and in prolonged concentration.

They also involve shifting attention from one subject or idea to another.

People with cognitive disturbances have trouble in perceiving accurate spatial relationships between objects, in comprehending or expressing language, and performing calculations, and in a number of other areas.

There is a decreased ability to track two processes at once, something we usually take for granted. This ability requires a rapid shifting of attention. Many porphyria patients during the height of an acute attack find this normally simple task as most difficult or impossible.

Suddenly there are two things that you need to monitor and pay attention to at the same time. This might have come easily to you at one time, but if you now have 'brain fog," it's very hard.

Brain fog is the having of conflicting emotions inside of you You csuddenly find that you have the inability to prioritize and use an effective order in carrying out details.

When there are two different things you want to do at the same time. Other dimensions of CNS disturbances often are present which leads to sometimes disorientation, anxiety and the sensation of confusion.

Because of the porphyria patient's cognitive problems one may find it very difficult to express confusion.

There is also the difficulty in handling sequences. Again prioritizing is next to impossible. It pertains to the mixing up of words and syllables when you're speaking.

It also includes the transposing or reversing of letters or numbers. In addition there is the having trouble tracking the flow of a normal conversation or the sequence of events in a story or article.

Often there is decreased mental stamina. Focus is next to impossible. Concentration is very hard.

Intellectual concentration is very fatiguing. Many porphyria patients relate that they find it most difficult if at all possible to finish watching a 90 minute video.

There is also decreased memory retrieval ability.

Decreased sense of internal certainty. Porphyria patients find them most unsure of common ordinarily experiences.

Many times porphyria patients reflect on the dimensions of brain fog and state that they experience a decreased ability to grasp the large whole concept.

For most acute porphyria patients the negative aspects of "brain fog" disappear as does the acute attack itself.

In those porphyria patients with chronic smoldering effects and especially for those with chronic pain "brain fog" will often linger. Exercise and quality rest are the essentials to fighting such "brain fog."

Urine Color An Evidential Clue in Suspecting Porphyria

The first porphyria test that most porphyria patient have had is that of urine tests. For most patients it was a 24 hour collection, but for others it has been the simple "window sill" test.

And the "window sill" test is about darkening and various colors. If one remembers the documentary film "The Maddening of King George III" you will recall vividly how the royal court paraded around hoisting the "royal pee" that was said to be a royal wine purple.

However in most people urine color ranges from light yellow to dark amber, depending on the concentration of solutes in the urine.

Pigment gives the urine the various colors and shades. The pigment is known as urochrome which characteristically is a yellow color.

Most often the urine of porphyria patients may only appear after the urine contacts the container or the water in the toilet bowl. Sometimes the urine has to sit in the sun or a bright light before the color appears.

For most people today it is unusual for individuals to even take note of coloration since most have been properly trained not to loiter in the bathroom therefore flushing away the urine, washing our hands and leaving, urine coloration unnoticed.

What do various urine colors mean in normally healthy persons? White or cloudy urine is most commonly a result of phosphaturia or due to pyruia.

Pink or red urine should prompt a call to your physician and a dipstick test for blood carried out. This could mean hemoglobinuria.

Red blood cells in the urine may be from kidney loss (termed "glomerular" blood cells) in patients with renal disease. Red cells in the urine of these individuals will usually be misshapen and accompanied by protein in the urine. If this is ruled out then a full urinalysis needs to be undertaken.

Complete urine testing (called "urinalysis") for the presence of bacteria and white blood cells, urine culture, cystoscopy, intravenous pyelogram, and/or other imaging studies my be necessary to clarify the source of the blood.

Some medications can turn the urine shades of red or pink. It is important to let the physician know every mediciation you have taken including OTC medications.

Orange urine may be produced by phenazopyridine (Pyridium) or ethoxazene (Serenium).

The drugs Rifampin, phenacetin, sulfasalazine, Vitamin C, riboflavin, and carrots will also turn urine dark yellow to orange.

Blue or green urine may be caused by a blue dye such as methylene blue, a component in several medications The anesthetic, propofol can also cause green coloration of the urine. Amitriptyline, indomethacin, resorcinol, triamterine, cimetidine, phenergan, and several multivitamins also lend a blue-green tint to the urine.

Brown or black urine may be due to copper or phenol poisoning The eating of large amounts of rhubarb, fava beans, or aloe can cause dark brownish black urine. The drugs chloroquine and primaquine, furazolidone, metronidazole, nitrofurantoin, cascara/senna laxatives, methocarbamol, and sorbitol can also produce a black urine.

In porphyria patients, again urine will present in various colors.The general spectrum runs from reddish wine to dark brown tea colors. Urine collected in a glass container and set in the sunlight will darken significantly in porphyria patients.
