Question

a 45 - year - old male was admitted to the hospital for an acute gastrointestinal infection. the offending organism was identified and successfully eradicated. during the routine lab work, however, abnormalities were found that prompted further investigation. among other abnormal findings, the patient exhibited elevated alkaline phosphatase and normal ggt. this is most likely indicating:
a) prostate cancer
b) liver cirrhosis
c) bone pathology
d) viral hepatitis
e) acute lymphocytic leukemia

Explanation:

Alkaline phosphatase (ALP) is an enzyme found in many tissues, including bone and liver. Gamma - glutamyl transferase (GGT) is mainly found in the liver. In bone pathology, ALP can be elevated due to increased osteoblast activity (as osteoblasts produce ALP), while GGT remains normal because there is no liver - specific pathology (GGT is not significantly affected by bone conditions). In liver cirrhosis, both ALP and GGT are often elevated. In viral hepatitis, ALP may be elevated (but usually not as prominently as in some obstructive or cirrhotic liver conditions) and GGT is also elevated. Prostate cancer (in the absence of bone metastasis) does not typically cause these specific ALP and GGT changes. Acute lymphocytic leukemia is more likely to present with changes in white blood cell counts, anemia, and thrombocytopenia rather than these specific ALP and GGT patterns.

Answer:

c) Bone Pathology
