Introduction. Few data are available on vitamin A deficiency in the gastric bypass population.Methods. We performed a retrospective chart review of gastric bypass patients (n=69, 74% female). The relationship between serum vitamin A concentration and markers of protein metabolism at 6-weeks and 1-year post-operative were assessed.Results. The average weight loss at 6-weeks and 1-year following surgery was20.1±9.1 kg and44.1±17.1 kg, respectively. At 6 weeks and 1 year after surgery, 35% and 18% of patients were vitamin A deficient, (<325 mcg/L). Similarly, 34% and 19% had low pre-albumin levels (<18 mg/dL), at these time intervals. Vitamin A directly correlated with pre-albumin levels at 6 weeks (r=0.67,P<0.001) and 1-year (r=0.67,  P<0.0001). There was no correlation between the roux limb length measurement and pre-albumin or vitamin A serum concentrations at these post-operative follow-ups. Vitamin A levels and markers of liver function testing were also unrelated.Conclusion. Vitamin A deficiency is common after bariatric surgery and is associated with a low serum concentration of pre-albumin. This fat-soluble vitamin should be measured in patients who have undergone gastric bypass surgery and deficiency should be suspected in those with evidence of protein-calorie malnutrition.

Nutritional Vitamin

A 42-year-old man who developed severe night blindness 15 years following jejunoileal bypass surgery for morbid obesity is described. Ophthamological testing, including dark adaptation, electroretinography and serum vitamin A levels, confirmed a diagnosis of vitamin A deficiency. Oral vitamin A 25,000 iu/day for two months resulted in a full recovery of visual deficits. Nutritional vitamin A deficiency is discussed in the context of intestinal bypass surgery.

Body Contour

Forty morbidly obese patients had plastic surgery to remove redundant tissues after gastric bypass surgery (GBP). The average weight reduction was 62 kg (range 29–95 kg) and the average age at operation was 36.5 years. Abdominoplasty was the most common procedure and no mortalities were recorded. The postoperative complications were related mostly to wound healing. The average hospitalization time was 8 days (range 5–11 days) and the patient's new body image was satisfactory.

Vitamin A Status

Yearling Hereford steers in store condition (average weight 585 lb) were fed whole wheat grain, or equal parts whole wheat grain and cereal hay, each diet supplying an estimated 2 lb of starch equivalent per head per day. After the different rations had been fed for 20 weeks, followed by hay-grain rations for 1 week to equalize gastro-intestinal fill, the cattle fed an all-grain ration had lost an average of 1.03 lb per day and those fed a hay-grain ration had lost 0.84 lb per day. The final difference in weight was not significant. All cattle remained in good health. Serum vitamin A levels declined during the experiment to subnormal levels, particularly in the all-grain group, but clinical signs of vitamin A deficiency ware not evident. Coprophagia, hair chewing, and biting of woodwork were observed, particularly in the all-grain group. It is concluded that all-grain rations may be satisfactorily used for drought feeding of cattle.

Obesity is now a common problem among HIV-infected patients receiving antiretroviral therapy<br />(ART). Until recently, HIV infection has been considered a contraindication to bariatric surgery for<br />various reasons. Insurance carriers have considered HIV a terminal disease, and surgeons have been<br />reluctant to operate HIV-infected patients because of this, as well as the associated risk of infectious<br />transmissions, although this has been changing. Gastric bypass surgery may be an option for some<br />patients who have failed diet and therapeutic lifestyle changes, modification in ART or other treatment<br />modalities for HIV/ART-related lipohypertrophy and obesity. However, few data are available regarding<br />HIV-related outcomes after such surgery and its impact on ART tolerability. The aim of this study is to<br />review bariatric surgery in HIV-infected patients.
