The Tale of TB


Since time immemorial, tuberculosis has been one of humanity's greatest nemesis. The earliest of human civilizations have suffered tremendous wrecks from this dreadful and fatal disease. Mummies from Egypt beginning 2400 BCE are proofs of the long-enduring curse of tuberculosis. Even the ancient Greece have their share of tuberculosis plague. It is from Greek literature that the word phthisis, which means consumption, was first discovered. It was prevalent that Hippocrates called it as the most fatal disease of their time.

The bacteria by the name of Mycobacterium tuberculosis is the identified cause of tuberculosis. More popularly known as TB, tuberculosis is misconceived by many as a disease exclusive to the lungs. While it mainly affects the lungs, some body parts, or almost every body part actually, can be affected by TB. The central nervous system, lymphatic system, circulatory system, genitourinary system, bones, and joints are just some other body parts that can be harmed by TB.

Mycobacterium tuberculosis is an aerobis bacterium that grows slowly that it takes 16 to 20 hours to divide. When this bacteria is inhaled, it settles around the lung area and its eventual multiplication leads to pneumonia. Lymph nodes connected to the lungs can also be affected by the infection. These lymph nodes become enlarged and its normal healthy processes gets badly affected. The bacteria that causes TB is highly probable to spread around the nearby areas and can reach other body parts as well. As a natural response to any bacteria, the human body's immune system would act by producing scar tissues (fibrosis) to fence the bacteria in the hope of containing its spread. The main goal of our body's immune system's response is to isolate the bacteria from the other tissues and organs of our body. If a person's immune system succeeds in doing so, the disease may be made inactive. People whose immune system successfully mitigates the spread of the bacteria generally show no signs and symptoms of the infection. However, constant production of fibrosis can lead to yet another bad effect. When massive deposits of calcium go to the scar tissues, calcification, the lymph nodes, and the scar tissues are likely to harden like stone.

The success of our body's immune system on quelling or at least, containing the harmful effects of the bacteria lies on the assumption that it remains well and healthy. But if our body's immune system is deteriorated by other factors or infections, TB bacteria is very well able of escaping the fences of the scar tissues and proceed with its natural way of living-- replication and invasion of other body parts. When this happens, pneumonia is very likely to happen again and again. Worse and highly probable, the bacteria may invade the kidneys, bone, spinal cord, and brain lining.

Mycobacterium tuberculosis is characterized by its staining capabilities. Even if the bacteria is treated, it can leave some strains especially if it had been treated with an acidic solution.

Mycobacterium tuberculosis has three other myobacteria-- M.microti, M.bovis, and M.africanum-- that can cause tuberculosis. There are also other myobacteria (nontuberculous myobacteria) that can cause TB-like pulmonary diseases, skin disease, and lymphadenitis.

The primary mode of transmission is the inhalation of infected air exhaled by a TB carrier. The bacteria is transported outside the lungs and mix with the air everytime a TB-infected person sneezes, spits, coughs, or even shouts. People at a close distance can then easily get easily get the bacteria and get infected.

When the TB infection is active, one that has not been contained by scar tissues, a number of symptoms can easily manifest. Patients with an active TB infection show symptoms of poor general health condition, noticeable weight loss, fever, and night sweats. If the lungs get so infected, chest pain, coughing up of sputum and/or blood, and poor breathing generally occur.

A combination of Myambutol, Rifadin, pyrazinamide, together with isoniazid is the most common treatment for TB infections that are active and progressive. In cases of patients not being able to comply with oral medications, injection of Streptomycin is given. The duration and intensity of medication depends on how grave or serious the case already is. Patients who had an early detection of the infection are more likely to be cured immediately than those at late detection.

Uric Acid Testing

Definition
Uric acid tests are tests that are done to measure the levels of uric acid in blood serum or in urine.
Purpose
The uric acid tests are used to evaluate the blood levels of uric acid for gout and to assess uric acid levels in the urine for kidney stone formation. The urine test is used most often to monitor patients already diagnosed with kidney stones, but it can also be used to detect disorders that affect the body's production of uric acid and to help measure the level of kidney functioning.
Uric acid is a waste product that results from the breakdown of purine, a nucleic acid. (Nucleic acids are the building blocks of DNA.) Uric acid is made in the liver and excreted by the kidneys. If the liver produces too much uric acid or the kidneys excrete too little, the patient will have too much uric acid in the blood. This condition is called hyperuricemia. Supersaturated uric acid in the urine (uricosuria) can crystallize to form kidney stones that may block the tubes that lead from the kidneys to the bladder (the ureters).
Precautions
Blood test
Patients scheduled for a blood test for uric acid should be checked for the following medications: loop diuretics (Diamox, Bumex, Edecrin, or Lasix); ethambutol (Myambutol); vincristine (Oncovin); pyrazinamide (Tebrazid); thiazide diuretics (Naturetin, Hydrex, Diuril, Esidrix, HydroDiuril, Aquatensen, Renese, Diurese); aspirin (low doses); acetaminophen (Tylenol); ascorbic acid (vitamin C preparations); levodopa (Larodopa); or phenacetin. These drugs can affect test results.
Certain foods that are high in purine may increase the patient's levels of uric acid. These include kidneys, liver, sweetbreads, sardines, anchovies, and meat extracts.
Urine test
Patients should be checked for the following medications before the urine test: diuretics, aspirin, pyrazinamide (Tebrazid), phenylbutazone, probenecid (Benemid), and allopurinol (Lopurin). If the patient needs to continue taking these medications, the laboratory should be notified.
The laboratory should also be notified if the patient has had recent x-ray tests requiring contrast dyes. These chemicals increase uric acid levels in urine and decrease them in blood.
Description
The uric acid blood test is performed on a sample of the patient's blood, withdrawn from a vein into a vacuum tube. The procedure, which is called a venipuncture, takes about five minutes. The urine test requires the patient to collect all urine voided over a 24-hour period, with the exception of the very first specimen. The patient keeps the specimen container on ice or in the refrigerator during the collection period.
Preparation
The uric acid test requires either a blood or urine sample. For the blood sample, the patient should be fasting (nothing to eat or drink) for at least eight hours before the test. The urine test for uric acid requires a 24-hour urine collection. The urine test does not require the patient to fast or cut down on fluids. Some laboratories encourage patients to drink plenty of fluids during the collection period.
Risks
Risks for the blood test are minimal, but may include slight bleeding from the puncture site, a small bruise or swelling in the area, or fainting or feeling lightheaded.
Normal results
Blood test
Reference values for blood uric acid vary from laboratory to laboratory but are generally found within the following range: Male: 2.1-8.5 mg/dL; female: 2.0-6.6 mg/dL. Values may be slightly higher in the elderly.
Urine test
Reference values for 24-hour urinary uric acid vary from laboratory to laboratory but are generally found within the following range: 250-750 mg/24 hours.
Abnormal results
The critical value for the blood test is a level of uric acid higher than 12 milligrams per deciliter (about 3.4 ounces).
Increased production of uric acid may result from eating foods that are high in purine. Increased uric acid levels due to overproduction may also be caused by gout, by a genetic disorder of purine metabolism, or by metastatic cancer, destruction of red blood cells, leukemia, or cancer chemotherapy.
Decreased excretion of uric acid is seen in chronic kidney disease, low thyroid, toxemia of pregnancy, and alcoholism. Patients with gout excrete less than half the uric acid in their blood as other persons. Only 10-15% of the total cases of hyperuricemia, however, are caused by gout.
Abnormally low uric acid levels may indicate that the patient is taking allopurinol or probenecid for treatment of gout; may be pregnant; or suffers from Wilson's disease or Fanconi's syndrome.
