Since vitamin K2 (VitK2) syrup prophylaxis has become a routine measure for neonates and young infants, the incidence of vitamin K deficiency (VitK-D) in infancy has markedly decreased. However, we recently experienced 2 infantile cases of VitK deficiency, in whom intracranial hemorrhage (ICH) was the first clinical sign of CMV hepatitis. Case 1 is a breast-fed boy who received VitK2 syrup orally at birth and at the age of 1 month. He did not suckle well and developed a generalized tonic convulsion twice at the age of 8 weeks. Case 2 is a mixed-fed boy who also received VitK2 syrup twice but developed vomiting and drowsiness at the age of 4 months. In both cases, laboratory tests showed anemia, leukocytosis, liver dysfunction with cholestasis, and coagulopathy, consistent with VitK-D abnormality. Their serological analyses showed that cytomegalovirus (CMV) IgG and IgM were both positive. In case 1, CMV DNA was positive, as judged by the PCR method. In case 2, CMV antigenemia was positive. Hence we diagnosed these two patients as having VitK-D ICH caused by CMV hepatitis with cholestasis. CMV hepatitis is a risk factor of VitK-D ICH.

Cystic fibrosis (CF) is the most common life-limiting inherited disease in the Caucasian population. Coagulation disorder in infancy is a rare presentation of CF, with few recent cases reported in the English literature. We report a case of an infant with CF who presented to our hospital with bruising, occult gastrointestinal bleeding, and anemia secondary to vitamin K deficiency.

The authors present a case of a 36-day-old infant with intracranial and intramuscular hemorrhage due to vitamin K deficiency bleeding, who received intramuscular vitamin K prophylaxis at birth. In this case, laboratory tests showed anemia, liver dysfunction with cholestasis, and coagulopathy, consistent with vitamin K deficiency abnormality. Serological analyses showed that cytomegalovirus immunoglobulin (Ig)M and IgG avidity were both positive. The infant was treated successfully with intravenous ganciclovir and blood products. This case suggests that it is imperative to meticulously investigate the etiology in neonates with late-onset hemorrhagic disease of the newborn. Cholestatic liver disease caused by congenital cytomegalovirus infection should be in mind in term infants who presented with late-onset hemorrhagic disease.

A 36-year-old woman with a 4 year history of lower legs edema, hypermenorrhea and melena without medical treatment was admitted to our hospital. At 18 days before admission, anasarca and general fatigue appeared and she was admitted to another hospital. Her hemoglobin concentration was 1.4 g/dl and chest X-ray showed cardiomegaly. Heart failure with severe chronic anemia was diagnosed, and blood transfusion was performed. Her hemoglobin concentration increased to 10 g/dl and the anasarca disappeared. The day after discharge, she was referred to our hospital with generalized convulsion. We diagnosed posterior reversible encephalopathy syndrome (PRES) from the typical MRI imaging. We started treatment and her consciousness recovered steadily. At a week after admission, left hemiparesis appeared. Her brain imaging revealed multiple intracranial hemorrhages. In addition, her visual disturbance revealed vitamin A and vitamin K deficiency. PRES sometimes occur secondary to blood transfusion, but secondary brain hemorrhage is rare. Her fat-soluble vitamin deficiency, which resulted from a peculiar eating habit, may have contributed to the brain hemorrhage.

We report herein a case of early vitamin K deficiency bleeding (VKDB) in a neonate associated with maternal Crohn's disease. A female neonate was born at 37 weeks' gestation and weighed 2778 g. She developed broad purpura on her back on day 1. Laboratory data showed anemia, prolonged coagulation time and elevated protein induced by vitamin K absence or antagonist-II. Early VKDB has not been reported in a neonate born from mother with active Crohn's disease. It is essential to give vitamin K selectively as soon as possible after birth to prevent early VKDB in neonates.

Acquired factor VII (FVII) deficiency in the absence of vitamin K deficiency, oral, synthetic liver dysfunction, or DIC is rare, with only a handful of cases published in literature. Congenital deficiency of FVII is well known but, little is known about secondary FVII deficiency and its management. The knowledge of this syndrome should avoid false diagnosis of congenital factor VII deficiency. Here, we present the report of a young woman who presented with pyelonephritis, anaemia, prolonged prothrombin time and normal activated partial prothrombin time (aPTT). She was diagnosed to have acquired FVII deficiency and this was the first such case with pyelonephritis.

Exocrine pancreatic insufficiency is an important cause of chronic malnutrition, secondary to maldigestion-malabsorption, which can be caused in children especially by cystic fibrosis, but also by other much rarer diseases. The case of a 6 months and 3 weeks old male pediatric patient is reported, who was admitted to the clinic for head and forearms bruising. Laboratory findings identified vitamin K deficiency as the cause of the cutaneous hemorrhagic syndrome. Further investigations revealed association of steatorrhea (which is a marker of fat malabsorption), iron-deficiency anemia and hypovitaminosis D, which had been produced by nutritional deficiencies caused by malabsorption syndrome. From the numerous disorders that could be associated with pancreatic insufficiency in children, the following conditions had been excluded: cystic fibrosis (mucoviscidosis), cow's milk protein intolerance, gluten-sensitive enteropathy (coeliac disease), Shwachman-Diamond syndrome, abetalipoproteinemia, etc. Based upon decreased levels of stool pancreatic elastase in repeated measurements, together with low serum lipase, the final diagnosis of exocrine pancreatic insufficiency was established. Treatment of this case consisted mainly in pancreatic enzyme replacement therapy, but also oral iron supplementation and dietary supplements with fat-soluble vitamins (A, D, E, K). The outcome was favorable, characterized by normalization of intestinal passage, ascending growth curve and normalization of the majority of laboratory tests values that were modified between the time of patient admission to our clinic and initiation of specific therapy (serum level of vitamin K, vitamin D and lipase, coagulation profile, hemoglobin and red blood cell indexes), as well as higher value of fecal pancreatic elastase.

This case involves a 73-year-old man who visited a clinic because he was experiencing dyspnea on exertion and acid reflux. He was diagnosed with anemia and referred for a medical check-up and treatment by his primary care physician. Iron deficiency anemia and prolonged prothrombin time were confirmed with a blood test and an abdominal enhanced CT revealed marked expansion of the afferent loop after a gastrectomy. The medical check-up revealed abnormal blood coagulation due to afferent loop obstruction, which resulted in vitamin K deficiency. He was supplemented with vitamin K, and surgery was performed for the afferent loop obstruction. Postoperatively, his anemia, nutritional status, serum vitamin K levels, and prothrombin time improved steadily. In conclusion, nutrient malabsorption may occur in cases of afferent loop obstruction and abnormal blood coagulation due to vitamin K deficiency.
