2. CASE ABSTRACT:
A 50 Year old male was admitted in Karpagam hospital on 21/2/2020
His chief complaints were cough, poor appetite, excessive joint pain for 1
week, chest pain for 1 month, weight loss, evening rise in temperature, and
breathlessness.
On physical examination he was found to be afebrile, conscious and
oriented. On laboratory examination his hemoglobin, total count, lymphocytes,
MCH, MCV, MCHC and RBC levels was found to be decreased. He had a past
medical history of tuberculosis and he discontinued the medications. Finally on
laboratory and specific investigation the patient was diagnosed as
PULMONARY TUBERCULOSIS.
3. • He was treated with following medication
ATT-CAT- II (8MONTHS)
T.Dolo
6. Reasons for admission
Cough
poor appetite
excessive joint pain for 1 week
chest pain for 1 month
weight loss
evening rise in temperature
breathlessness
14. CAUSES:
Tuberculosis is caused by bacteria (Mycobacterium tuberculosis) that spread from person to
person through microscopic droplets released into the air.
This can happen when someone with the untreated active form of tuberculosis coughs, speaks,
sneezes, spits, laughs or sings.
RISK FACTORS:
Low body weight
Babies and young children, whose immune systems have not matured
People with chronic conditions such as diabetes or kidney disease
People with HIV/AIDS
Organ transplant recipients
Cancer patients undergoing chemotherapy
People receiving certain specialized treatments for autoimmune disorders

drug
inhibition of mycolic acid synthesis
inhibits bacterial RNA synthesis by binding strongly to
the beta subunit of DNA-dependent RNA polymerase,
preventing attachment of the enzyme to DNA, and thus
blocking initiation of RNA transcription
inhibition of mycolic acid synthesis
inhibits the synthesis of metabolites, subsequently
impairing cell metabolism and cell multiplication
eventually leading to cell death
inhibit normal bacterial protein synthesis

20. DRUG-DRUG INTERACTION
ISONIAZID -- ACETAMINOPHEN
Concurrent use of ACETAMINOPHEN and ISONIAZID may result in an increased risk of hepatotoxicity.
Mechanism-inhibition of CYP2E1-mediated metabolism of acetaminophen by isoniazid.
Acetaminophen use should be avoided or limited in patients taking isoniazid.
ISONIAZID-RIFAMPIN
Concurrent use of RIFAMPIN and ISONIAZID may result in hepatotoxicity.
Mechanism- increased isoniazid metabolism
For patients on concurrent isoniazid and rifampin, monitor liver function tests
PYRAZINAMIDE-RIFAMPIN
Concurrent use of PYRAZINAMIDE and RIFAMPIN may result in severe hepatic injury.
Patients should be monitored throughout the entire course of therapy since a majority of patients have onset of
symptoms of liver injury after the fourth week of therapy.
21. DRUG-FOOD INTERACTION
ACETAMINOPHEN-CABBAGE
Concurrent use of ACETAMINOPHEN and CABBAGE may result in decreased acetaminophen
effectiveness.
Cabbage may enhance the glucuronidation of acetaminophen to inactive metabolites.
RIFAMPIN-FOOD
Concurrent use of RIFAMPIN and FOOD may result in decreased rifampin concentrations.
Rifampin should be administered one hour before or two hours after a meal with a full glass of water.
ISONIAZID-FOOD
Concurrent use of ISONIAZID and FOOD may result in decreased isoniazid exposure.
Isoniazid should be administered on an empty stomach.
22. PATIENT COUNSELLING
• Educate the patient about the disease severity, the importance of adherence to therapy
and the complications of tuberculosis.
• Patient are advice to use tissues to cover when they cough and sneezes
• Tissues should be disposed appropriately and not left on outer space
• A surgical mask must worn by the patient whenever they leave the isolation room.
• Take medications properly.
23. PATIENT COUNSLLING-BASED ON DRUG
PROFILE
• Isoniazid should be administered on an empty stomach
• Rifampin should be administered one hour before or two hours after a meal with a
full glass of water.
• Rifampin stains body fluids such as urine, saliva, sweat, sputum, etc. orange red
which is harmless.
