| description | BACKGROUND
Celiac disease (CD) is usually missed, if the serology is negative. We aimed to evaluate the clinicopathological characteristics of seronegative CD (SNCD) and its response to gluten-free diet (GFD) in adult patients.
METHODS
This observational study was carried out at the Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, Pakistan from 2009 to 2015. All consecutive adult patients (≥17 years) with features of marked villous atrophy (Marsh class≥III) on duodenal biopsy, negative tissue transglutaminase IgA and IgG antibodies (anti-tTg IgA and IgG) and human leukocyte antigen (HLA) DQ2 or DQ8 serotypes were studied. Clinical characteristics, laboratory parameters, and response to GFD were analyzed by SPSS software version 20. Median and interquartile range (IQR) were used for summarizing quantitative data. Frequency (percentages) was used for qualitative data.
RESULTS
A total of 12 patients with median age of 31.5 years (IQR: 19.75-46.75 years), of whom five (41.6%) were men were studied. The presenting complaints were: weight loss in 11 (91.6%) and abdominal pain in 9 (75%) patients. Anemia was observed in 10 (83.3%) patients with median hemoglobin of 9.5 g/dL (IQR: 6.3-13.25 g/dL). Median alanine transaminase (ALT) was 21 U/L (IQR: 13–27 U/L) and median albumin was 3 g/dL (IQR: 2.4-3.6 g/dL). Anti-tTg IgA and IgG were negative in all patients. HLA DQ serotyping showed homozygous DQ2 and DQ8 in four and one patients, respectively; while heterozygous DQ2 and DQ8 in five and two patients, respectively. All patients were advised to receive GFD. Nine (75%) patients showed complete clinical response. Two patients were non-compliant and one with non-alcoholic fatty liver disease (NAFLD)-related cirrhosis had partial clinical response. Out of the nine responders, two patients showed response within 6 months while the remaining showed improvement over a year period.
CONCLUSION
The diagnosis of SNCD is rewarding as it responds favorably to GFD in most patients. HLA serology provides an important tool for diagnosis of this entity. |
