Patient presents with Hb-5 g%, TLC-9000/cc, DLC-Neutrophils-3%, Lymphoblasts-75% and fever for 1 mth. Drug used is – a) iv Ciprofloxacin b) Colony stimulating factor c) Packed cell transfusion d) Oral Ciprofloxacin
**Question:** Patient presents with Hb-5 g%, TLC-9000/cc, DLC-Neutrophils-3%, Lymphoblasts-75% and fever for 1 mth. Drug used is –
a) iv Ciprofloxacin
b) Colony stimulating factor
c) Packed cell transfusion
d) Oral Ciprofloxacin
**Core Concept:** Leukemia is a group of blood-related cancers characterized by an overproduction of abnormal white blood cells. In this case, the patient has lymphoblasts constituting 75% of TLC.
**Why the Correct Answer is Right:** Lymphoblasts are immature lymphocytes, and their overproduction indicates acute lymphoblastic leukemia (ALL). In this context, the correct answer is iv Ciprofloxacin, which is a potent antibiotic used to treat bacterial infections, especially those involving Gram-negative bacteria. It helps to cover the bacterial infection that might be coexisting with the leukemia.
**Why Each Wrong Option is Incorrect:**
**A. iv Ciprofloxacin (Correct)**: As mentioned above, iv Ciprofloxacin is used to treat bacterial infections, which is essential in the context of a patient with leukemia.
**B. Colony Stimulating Factor (CSF):** Colony-stimulating factors are substances that stimulate the growth and differentiation of hematopoietic cells, particularly granulocytes and macrophages. In this context, CSF would be used to stimulate the bone marrow to produce normal blood cells, not to treat bacterial infections.
**C. Packed Cell Transfusion:** Packed cell transfusion involves transfusing red blood cells to correct anemia. While anemia is a common complication in leukemia, this option focuses on treating the anemia rather than addressing the underlying issue of leukemia.
**D. Oral Ciprofloxacin:** Oral Ciprofloxacin is less potent than IV Ciprofloxacin in terms of fighting bacterial infections, and thus, it is less appropriate for treating the patient's severe infection.
**Clinical Pearl:** It is essential to differentiate between leukemia and its complications like bacterial infections. In this case, the patient has both leukemia and a severe bacterial infection, necessitating the use of iv Ciprofloxacin.
**Correct Answer Explanation:** In the context of the patient's presentation, iv Ciprofloxacin is used to treat the bacterial infection that is likely coexisting with the leukemia. The patient's severe infection requires a potent antibiotic like iv Ciprofloxacin, while oral Ciprofloxacin is less potent due to the patient's low hemoglobin (Hb-5 g%) and neutropenia (TLC-9000/cc with neutrophils <1% and lymphocytes <1%). **Why Each Wrong Option is Inappropriate:** **A. Colony-stimulating Factor (CSF):** Although CSF can help stimulate hematopoiesis, it is primarily used to stimulate the growth and
