Cerebral Venous Sinus Thrombosis following Diagnostic Curettage in a Patient with Uterine Fibroid

Central retinal vein occlusion secondary to severe iron-deficiency anaemia resulting from a plant-based diet and menorrhagia: a case presentation

In this case presentation, we present a young vegan patient who developed a CRVO secondary to severe iron-deficiency anaemia (IDA) attributable to menstrual losses and limited iron intake. CRVO is a rare complication of IDA.

With rising calls for sustainable diets and rising evidence for a plant-based diet, there has been a rise in popularity of such diet forms. While there are ocular benefits from this diet trend, the potential for nutritional deficiencies including iron needs to be monitored especially in susceptible individuals. Iron is essential for retina metabolism and function; however, excess iron contributes to disease states in the eye. Therefore, supplementation needs to be judicious.

[Iron deficiency, thrombocytosis and thromboembolism]

Iron deficiency, the most common nutritional deficiency worldwide, is often associated with reactive thrombocytosis. Although secondary thrombocytosis is commonly considered to be harmless, there is accumulating evidence that elevated platelet counts, especially in the setting of iron deficiency, can lead to an increased thromboembolic risk in both arterial and venous systems. Here we present the mechanisms of iron deficiency-induced thrombocytosis and summarize its clinical consequences especially in patients with inflammatory bowel diseases, chronic kidney disease or cancer. We hypothesize that iron deficiency is an underestimated thromboembolic risk factor, and that iron replacement therapy can become an effective preventive strategy in a variety of clinical settings.
