- A 35-year-old woman with a history of recurrent anaemia was noted to have target cells and Howell-Jolly bodies on a blood film examination.

Investigations revealed:

Haemoglobin 7.0 g/dL (11.3-16.5)
MCV 77 fl (80-96)
MCH 26.2 pg (28-32)
Serum B12 140 ug/L (160-760)
Red cell folate 95 ug/L (160-640)
Serum ferritin 10 ug/L (15-300)

What disease specific antibody is most likely to be present?

1) Anti-endomysial.

2) Anti-gastric parietal cell.

3) Anti-glutamic acid decarboxylase.

4) Anti-intrinsic factor.

5) Antimitochondrial.

This was the one which was the toughest one Kudos to u Mytimne atleast u tried n didnt give up

1) Anti-endomysial.

The patient has hyposplenism as suggested by the blood film and a mixed anemia. Celiac disease could therefore fit the above picture with anti-endomysial antibodies being the most appropriate selection from the above list. Antimitochonrial antibodies are seen in PBC, anti-gastric and anti intrinsic Abs are seen in pernicious anemia. Anti-GAD abs are found in auto-immune DM.

Screening for celiac disease should include high-risk groups such as anemia (iron or folate deficiency), hyposplenism, reduced bone density and infertility.

"Anti-endomysial IgA antibodies are extremely specific markers for CD and for dermatitis herpetiformis. These antibodies are directed to a component of the gut endomysial (connective tissue surrounding smooth muscle fibers of the gut)."

Wouldn't have known this one .........

Target cells and Howell-Jolly bodies are seen in megaloblastic anemia, I pick anti-intrinsic factor antibodies, which is a cause of vitamin B12 deficiency and this anemia.
