Prevalence of Coeliac Disease in Omani Adults with Iron Deficiency Anaemia of Unknown Cause: Case-finding study.

Objectives: This study aimed to estimate the serological prevalence of coeliac disease in patients with iron deficiency anaemia (IDA) of unknown cause at a primary healthcare facility in Oman. Methods: This prospective case-finding study was conducted at the primary care clinics in Sultan Qaboos University Hospital, Muscat, Oman from September 2018 to June 2020. Patients aged 18 to 55 years, with a haemoglobin (Hb) level <11.5 g/dL for males and <11.0 g/dL for females and a ferritin level <30 ng/mL for males and <13 ng/mL for females, were included in the study. Blood samples were obtained for initial serological screening using serum immunoglobulin (Ig)A level; those samples with normal levels of IgA, IgA anti-tissue transglutaminase antibody (tTG) and IgA anti-deamidated gliadin peptide (DGP) were determined. Positive IgA-tTG test was confirmed using IgA-endomysial antibodies. Patients with low IgA levels were tested using IgG-tTG and IgG-DGP. Results: A total of 104 patients participated in this study. Eight patients (7.7%) were found to have a positive serological screening result for coeliac disease; of these patients, three (37.5%) had a positive IgA-tTG result. Two of those three (66.7%) had a positive IgA-endomysial antibody. The IgA-DGP result was positive in seven (6.7%) of the 104 patients. Out of those seven patients, two also had a positive IgA tTG. Conclusion: Coeliac disease is not a rare disorder. There is a need to increase awareness among healthcare professionals about coeliac disease and its non-classical manifestations such as IDA.

Etiological profile of Omani women with recurrent pregnancy loss.

OBJECTIVE: To define the different causes of recurrent pregnancy loss (RPL) among Omani women. METHODS: This retrospective study included all women with RPL seen between June 2006 and March 2012 in the RPL outpatient clinic in Sultan Qaboos University hospital, Muscat, Oman. The data were collected from the Hospital Information System by screening the electronic records of these patients. The sample size gathered during the study period was 290 women. RESULTS: One hundred and forty (48%) of the examined patients had an identifiable cause for RPL, while in 150 (52%), no cause was identified. The most common causes were immunological factors (35.4%) and the least common were environmental factors (1.7%). Other causes implicated included: chromosomal abnormalities (8%), anatomical factors (9.4%), endocrine disorders (29.8%), infectious causes (3%), and thrombotic causes (12.7%). CONCLUSION: Recurrent pregnancy loss is prevalent among Omani women. The etiological profile of RPL in Omani women is consistent with that reported elsewhere according to previously published studies, with minor variations.
