Deep vein thrombosis and pulmonary embolism in a child with diabetic ketoacidosis and protein s deficiency: a case report

Fatal Pulmonary Embolism Due to Inherited Thrombophilia Factors in a Child With Wolfram Syndrome

Wolfram syndrome-1 is a rare and severe autosomal recessive neurodegenerative disease characterized by diabetes mellitus (DM), optic atrophy, diabetes insipidus, and deafness. Poorly controlled type 1 DM increases the risk for thrombosis. However, coexistence of DM and hereditary thrombosis factors is rarely observed. Here we present the case of a 13.5-year-old, nonfollowed girl newly diagnosed with poorly controlled Wolfram syndrome on the basis of the results of clinical and laboratory examinations. On the eighth day after diabetic ketoacidosis treatment, pulmonary embolism developed in the subject. Thrombus identified in the right atrium using echocardiography was treated by emergency thrombectomy. Homozygous mutation in the methylenetetrahydrofolate reductase gene C677T, heterozygous factor-V Leiden mutation, and active protein C resistance were identified in the patient. The patient was lost because of a recurring episode of pulmonary embolism on the 86th day of hospitalization. We present this case to highlight the need for investigating hereditary thrombosis risk factors in diabetic patients in whom thromboembolism develops.

Fatal Pulmonary Thromboembolism in Patients with Diabetic Ketoacidosis: A Seven-Case Series and Review of the Literature

Diabetes mellitus is a well-recognized risk factor for arterial thrombosis, however its relationship to venous thromboembolism (VTE) in adults is still debated. We report here seven cases of fatal pulmonary thromboembolism in adults with diabetic ketoacidosis as the underlying cause. In four of seven cases, there was no prior diagnosis of diabetes mellitus and patients were newly diagnosed either upon presenting to the hospital in diabetic ketoacidosis (DKA) or at the time of autopsy by the vitreous glucose concentration. None of the patients had family history, recent surgery, recent trauma, long distance travel, or other strong risk factors for VTE. Only two patients had a body mass index greater than 35 kg/m² and the same two cases had hospital stays that ranged from three to five days. We believe that DKA is a frequently unrecognized and sometimes overlooked risk factor for VTE, particularly in the forensic setting where routine toxicology and vitreous glucose analysis may not be standard practices. We encourage forensic pathologists, medical examiners, and coroners to consider the possibility of diabetic ketoacidosis as a risk factor, and in some cases, the underlying etiology for pulmonary thromboembolism. Additionally, we recommend vitreous glucose testing be performed if there are any signs of DKA or diabetes present, such as acetone in the blood.

Presumed paradoxical embolus in a patient with diabetic ketoacidosis

Thrombotic complications figure among the most frequent causes of mortality in diabetic ketoacidosis (DKA) and hyperosmolar state. We report the case of a 55-year-old woman presenting with DKA whereby a newly discovered patent foramen ovale was found due in part to the observation of bilateral deep vein thrombosis in legs, bilateral multiple pulmonary embolisms, and left subclavian acute artery thrombosis. Diabetes is known as a hypercoagulability state, and DKA is rising as a risk factor for vascular events. The importance of prophylactic anticoagulation should be emphasized in this setting.
