Table 4. Usefulness of both IEL flow cytometric pattern and IF pattern for the diagnosis of CD in patients with lymphocytic enteritis (Marsh 1 type lesion).

Parameter	Serum anti-TG2+	Serum anti-TG2−			Overall
	‘Gold standard’+n = 12	‘Gold standard’+n = 8	‘ProbableCD’ n = 7*	‘Non-celiac’n = 43	‘Gold standard’+n = 20
Complete FCP	9	4	7	0	13 (65%)**
Incomplete FCP	3	3	0	2	6 (30%)**
IF pattern	8	4+	1	3	12 (60%)
Incomplete/IF pattern	1	2	0	0	3 (15%)

FCP: Flow cytometric pattern.

*A GFD could not be started in 3 patients (1 not accepted, 2 non-symptomatic first degree relatives); Response to a GFD not evaluable in 4 patients (2 lost in follow-up, 2 with associated psychiatric disorders).

⁺1 patient with an isolated CD IF pattern at inclusion developed positive EmA and the complete CD cytometric pattern in a follow-up duodenal biopsy.

**Positive FCP (65%+30% = 95%) vs positive IF pattern (60%), p = 0.039 (McNemar Test).
