The outcome measures were psychological general well-being and the plasma total homocysteine (tHcy) level, marker of B vitamin status.<\/p>\n<p style=\"text-align: justify\">Fifty-seven patients (88%) completed the trial. The tHcy level was baseline median 11.7 micromol\/L (7.4-23.0), significantly higher than in matched population controls [10.2 micromol\/L (6.7-22.6)].

Apart from generalized weakness, he reported no other symptoms. Physical examination revealed carpopedal spasm, clubbing of fingers and cachexia (body mass index 14 kg\/m2). This patient was found to have several unusual features of celiac disease, including a low vitamin B12 level causing anemia, severe hypocalcemia and electrolyte disturbances as the initial manifestations, minimal gastrointestinal symptoms, and negative tTG-antibodies.<\/p>\n<p style=\"text-align: justify\">Blood tests showed severe hypocalcemia, with a total serum calcium of 1.06 mmol\/L (normal range [NR] 2.05-2.55 mmol\/L). He also had low serum potassium (2.8 mmol\/L; NR 3.5-5.5 mmol\/L) and magnesium (0.36 mmol\/L; NR 0.65-1.05 mmol\/L). Other significant results included hemoglobin 10.6 g\/dL (NR 13-18 g\/dL), mean corpuscular volume 98.1 fl (NR 82-98 fl), vitamin B12 157 ng\/L (NR &gt; 165 ng\/L), folate 2.8 g\/L (NR 3.1-17.5 \u03bcg\/L), ferritin 252 \u03bcg\/L (NR 30-250 \u03bcg\/L), prothrombin time 20 s (NR 11-14 s), thyroid stimulating hormone 0.87 mu\/L (NR 0.35-4.5 mu\/L), phosphate 0.57 mmol\/L (NR 0.8-1.45 mmol\/L), albumin 32 g\/L (NR 34-48 g\/L) and alkaline phosphatase 313 IU\/L (NR 47-141 IU\/L). Subsequent results revealed vitamin D deficiency with a low serum 25-OH vitamin D of &lt; 7 \u03bcg\/L (NR 7-40 \u03bcg\/L), a low 24-hour urinary calcium excretion of 0.9 mmol (NR 2.5-7.5 mmol) and a raised serum parathyroid hormone of 22.7 pmol\/L (NR 1.6-6.9 pmol\/L). Serology for tissue transglutaminase (tTG) antibodies was negative, and a serum IgA level of 4.95 g\/L (NR 0.8-4.0 g\/L) excluded selective IgA deficiency. Electrocardiograph at admission showed prolonged QT interval.<\/p>\n<p style=\"text-align: justify\">In view of cachexia, clubbing and negative tTG-antibodies, he was further investigated for an occult malignancy. Barium meal and follow through showed dilated proximal bowel loops and absence of normal feathery pattern of the jejunum, features suggestive of a malabsorptive state. Upper gastroscopic examination was normal; however, the duodenal biopsy showed partial and subtotal villous atrophy with increased intra-epithelial lymphocyte infiltration, consistent with the diagnosis of celiac disease.<a href=\"#footnote_16_3322\" id=\"identifier_20_3322\" class=\"footnote-link footnote-identifier-link\" title=\"Schmidt K, Powari M, Shirazi T, Vaidya B.
