CLINICAL IMMUNOLOGY AND SEROLOGY
FIFTH EDITION EXAM SCRIPT 2026 QUESTIONS
WITH CORRECT SOLUTIONS 100% VERIFIED
◉ Hepatitis Be antigen. Answer: presence indicates active viral
replication, and HBV is most infectious when the Be antigen is
detectable
◉ antibodies to HBV antigen. Answer: appear shortly after the
antigen disappears
presence in patients with acute HBV suggests that the infection is
resolving
◉ antibodies to HBV antigen. Answer: in most chronic cases, these
indicate that the infection is resolving or that there is no
complicating liver disease
may be seen in chronic asymptomatic
◉ HCV. Answer: average incubation period is 7-8 weeks
may be acute or chronic
,~50% of infected patients are chronic carriers, ~20% of those
patients eventually develop cirrhosis and ~20% of those patients
develop hepatocellular carcinoma
◉ secondary syphilis. Answer: usually occurs 6-8 weeks after the
chancres first appear
characterized by a generalized rash
secondary lesions may develop in the eyes, joints, or CNS
lesions are highly contagious, but heal within 2-6 weeks
serologic tests are positive
antibodies are mainly IgG
◉ latent stages of syphilis. Answer: contagious and generally
considered to begin after the second year of infection
no clinical symptoms, although serologic tests are still positive
, after 4 years, it's not usually contagious but can be passed from
mother to fetus
◉ tertiary syphillis. Answer: characterized by granulomatous lesions
known as gummata
these lesions may develop in skin, mucous membranes, joints,
muscles, and bones, causing little or no clinical problems
◉ tertiary syphillis. Answer: ~80% of patients experience CNS
involvement, which can result in paralysis or dementia
~10% of patients develop CV problems, which can result in aortic
aneurysm
◉ congenital syphills. Answer: can be transmitted to a fetus after
18th week of gestation
treatment of the infected mother before the 18th week will prevent
infection, treatment after will cure it
◉ syphilis treatment. Answer: drug of choice is penicillin, but can
use tetracycline or erythromycin
