“…En cuanto a las manifestaciones oculares, se han publicado varios casos clínicos que sacan a la luz el amplio espectro de manifestaciones derivadas de la DVA tras técnicas de cirugía bariátrica malabsortiva, fundamentalmente en forma de nictalopia, xeroftalmia y retinopatía (8,9). Incluso se ha descrito un caso de ceguera neonatal transitoria en un paciente hijo de una madre con hipovitaminosis A (10).…”

Vitamin A defi ciency is uncommon in developed countries. Bariatric surgery emerges a an important risk factor for vitamin A defi ciency and some clinical cases have been described, specially associated with malabsorptive surgical techniques, such as biliopancreatic diversion. In this paper we report a clinical case of a patient who developed blindness, ophthalmological disease and cutaneous alterations secondary to vitamin A defi ciency after gastric bypass. A review of other publications and recommendations on this important subject is also included. ResumenLa defi ciencia de vitamina A es infrecuente en los países desarrollados. La cirugía bariátrica constituye un factor de riesgo de defi ciencia de esta vitamina. Se han descrito varios casos en pacientes sometidos a técnicas con un importante componente malabsortivo, como la derivación biliopancreática. En este artículo se describe un caso de defi ciencia clínica de vitamina A con manifestaciones oculares y cutáneas tras bypass gástrico y se revisan las publicaciones sobre este tema y las recomendaciones para la prevención de esta importante complicación.

“…A study showed that 10% of patients after a Roux-en-Y procedure developed vitamin A deficiency [17], while both ocular and skin symptoms may become evident several years afterwards [18]. The mechanism of vitamin A deficiency relates to fat-soluble vitamin malabsorption induced by bile acid deficiency and possibly to zinc deficiency that impairs protein synthesis and transport of retinol from the liver to other organs [14].…”

Bariatric surgery aims at weight reduction of severely obese patients. The Roux-en-Y technique is one of the most common bariatric procedures and is occasionally accompanied by nutrient insufficiencies and metabolic changes. According to the literature, skin architecture and immunity change after bariatric surgery and may lead to inflammation and increased susceptibility to pathogens. Additionally, vitamin and mineral deficiencies frequently develop in these patients and affect the skin's defense mechanisms, possibly contributing to dermatological complications. Knowledge and recognition of skin changes after bariatric surgery make an important asset for the dermatologist and help in the proper treatment of these patients. We report 2 cases of infectious skin lesions where vitamin and trace element deficiencies have possibly contributed to their persistence and resistance to traditional treatments.

“…Most cases in the latter relate to inflammatory bowel disease, pancreatitis, upper gastrointestinal surgery and chronic liver disease (including alcoholism). [1][2][3][4] We present a case series of patients who had hypovitaminosis A and responded markedly to oral vitamin A supplementation, resulting in an improved final visual outcome.…”
