Clinical outcome and neurological development of patients with biliary atresia associated with a bleeding tendency: a single institution experience. Surg Today 2024; 54:452-458. [PMID: 37650941 DOI: 10.1007/s00595-023-02744-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 08/20/2023] [Indexed: 09/01/2023]
Abstract
PURPOSE We compared the clinical features of patients with biliary atresia (BA) associated with a bleeding tendency (BT) at the time of the diagnosis with those of patients without a bleeding tendency (NBT). METHODS The patients' background characteristics, age in days at the first visit, Kasai portoenterostomy (KPE), and postoperative course were retrospectively analyzed. RESULTS Nine of the 93 BA patients (9.7%) showed a BT, including 7 with intracranial hemorrhaging (ICH), 1 with gastrointestinal bleeding, and 1 with a prothrombin time (PT) of 0%. The age at the first visit was 62 ± 12 days old for BT patients and 53 ± 27 days old for NBT patients (p = 0.4); the age at KPE was 77 ± 9 days old for BT patients and 65 ± 24 days old for NBT patients (p = 0.2); the time from the first visit to surgery was 13 ± 7 days for BT patients and 11 ± 10 days for NBT patients (p = 0.5); and the native liver survival rate was 56% for BT patients and 58% for NBT patients (p = 1), with no significant difference in any of the parameters. The neurological outcomes of survivors of ICH were favorable. CONCLUSIONS Appropriate BT correction allowed early KPE even after ICH, resulting in native liver survival rates comparable to those of NBT patients without significant neurological complications.

Higher levels of circulating desphospho-uncarboxylated matrix Gla protein over time are associated with worse survival: the prospective Maastricht Intensive Care COVID cohort. J Intensive Care 2023; 11:63. [PMID: 38111069 PMCID: PMC10726599 DOI: 10.1186/s40560-023-00712-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 12/09/2023] [Indexed: 12/20/2023] Open
Abstract
BACKGROUND Extra-hepatic vitamin K-status, measured by dephosphorylated uncarboxylated matrix Gla protein (dp-ucMGP), maintains vascular health, with high levels reflecting poor vitamin K status. The occurrence of extra-hepatic vitamin K deficiency throughout the disease of COVID-19 and possible associations with pulmonary embolism (PE), and mortality in intensive care unit (ICU) patients has not been studied. The aim of this study was to investigated the association between dp-ucMGP, at endotracheal intubation (ETI) and both ICU and six months mortality. Furthermore, we studied the associations between serially measured dp-ucMGP and both PE and mortality. METHODS We included 112 ICU patients with confirmed COVID-19. Over the course of 4 weeks after ETI, dp-ucMGP was measured serially. All patients underwent computed tomography pulmonary angiography (CTPA) to rule out PE. Results were adjusted for patient characteristics, disease severity scores, inflammation, renal function, history of coumarin use, and coronary artery calcification (CAC) scores. RESULTS Per 100 pmol/L dp-ucMGP, at ETI, the odds ratio (OR) was 1.056 (95% CI: 0.977 to 1.141, p = 0.172) for ICU mortality and 1.059 (95% CI: 0.976 to 1.059, p = 0.170) for six months mortality. After adjustments for age, gender, and APACHE II score, the mean difference in plasma dp-ucMGP over time of ICU admission was 167 pmol/L (95% CI: 4 to 332, p = 0.047). After additional adjustments for c-reactive protein, creatinine, and history of coumarin use, the difference was 199 pmol/L (95% CI: 50 to 346, p = 0.010). After additional adjustment for CAC score the difference was 213 pmol/L (95% CI: 3 to 422, p = 0.051) higher in ICU non-survivors compared to the ICU survivors. The regression slope, indicating changes over time, did not differ. Moreover, dp-ucMGP was not associated with PE. CONCLUSION ICU mortality in COVID-19 patients was associated with higher dp-ucMGP levels over 4 weeks, independent of age, gender, and APACHE II score, and not explained by inflammation, renal function, history of coumarin use, and CAC score. No association with PE was observed. At ETI, higher levels of dp-ucMGP were associated with higher OR for both ICU and six month mortality in crude and adjusted modes, although not statistically significantly.

Abstract
Hyperemesis gravidarum (HG), severe nausea and vomiting in pregnancy, can lead to vitamin deficiencies. Little is known about HG-related vitamin K deficiency. We aimed to summarise available evidence on the occurrence of HG-related vitamin K deficiency and corresponding maternal and neonatal complications. A systematic review was conducted, searching Medline and EMBASE from inception to 12 November 2020. We identified 1564 articles, of which we included fifteen in this study: fourteen case reports (n 21 women) and one retrospective cohort study (n 109 women). Nine out of twenty-one women reported in case reports had a prolonged prothrombin time (PT). The cohort study measured PT in 39/109 women with HG, of whom 10/39 women (26 %) had prolonged PT. In total, 30-50 % women received vitamin K supplementation after vitamin K deficiency had been diagnosed. Four case reports (n 4 women) reported corresponding maternal complications, all consisting of coagulopathy-related haemorrhage. Nine case reports (n 16 neonates) reported corresponding neonatal complications including intracranial haemorrhage (n 2 neonates) and embryopathy (n 14 neonates), which consisted of Binder phenotype (n 14 neonates), chondrodysplasia punctata (n 9 neonates) and grey matter heterotopia (n 3 neonates). In conclusion, vitamin K deficiency and related complications occur among women with HG. In our systematic review, we were unable to assess the incidence rate.

Severe Coagulopathy in a Patient With Short Bowel Syndrome. J Emerg Med 2022; 62:e101-e104. [PMID: 35109974 DOI: 10.1016/j.jemermed.2021.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Accepted: 12/23/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Short bowel syndrome (SBS) refers to a malabsorptive state caused by extensive resection of the intestinal tract that leads to chronic diarrhea, electrolyte disturbances, and malnutrition. Although relatively uncommon, patients with SBS can present to the emergency department with more serious complications that are potentially life-threatening. Among these complications, coagulopathy secondary to SBS is an underrecognized condition. CASE REPORT We present a case of severe coagulopathy secondary to vitamin K deficiency in SBS. The patient presented with unexplained coagulopathy and spontaneous bleeding in multiple organs. With a review of surgical history and detailed clinical evaluation, SBS complicated with vitamin K deficiency was diagnosed, and the patient was treated successfully. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: When a patient with a history of repeated intestinal surgery presents with diarrhea, malnutrition, or electrolyte abnormalities, emergency physicians should suspect SBS. Among complications of SBS, vitamin K deficiency is a rare but serious cause of unexplained coagulopathy presenting to the emergency department. Understanding the pathophysiology of SBS facilitates early identification of complications and improves patient outcomes.

Intracranial haemorrhage associated with Vitamin K deficiency in Egyptian infants. Acta Paediatr 2021; 110:2937-2943. [PMID: 34196053 DOI: 10.1111/apa.16011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 06/27/2021] [Accepted: 06/28/2021] [Indexed: 11/30/2022]
Abstract
AIM Intracranial haemorrhage (ICH) in infancy is a rare life-threatening event. The aim of this review is to highlight the association of ICH and potentially preventable vitamin K deficiency and to describe risk factors, presentation and outcome. METHODS Original published data on ICH related to vitamin K deficiency during 2008-2012 were extracted from records of participating centres in Egypt (Cairo and Delta region). Full data on 70 infants (0-24 weeks) have been reported in three publications. RESULTS The first study involved premature infants where ICH was potentially preventable with administration of parenteral vitamin K prophylactic doses to mothers ahead of imminent preterm delivery. The other 2 studies involved term newborns and infants. ICH due to early or classic vitamin K deficiency was reported in nine patients while 44 were due to late vitamin K deficiency. Main risk factors for late onset were exclusive breastfeeding, persistent diarrhoea and/or prolonged antibiotic therapy. CONCLUSION Vitamin K deficiency bleeding is a relatively frequent problem underlying ICH in infancy. Prophylactic vitamin K to mothers when anticipating preterm labour or a vitamin K boost in exclusively breast-fed infants with prolonged antibiotic usage and, or, persistent diarrhoea might have an impact on prevention and outcome.

Abstract
OBJECTIVE Despite operational guidelines, anecdotal evidence suggests that newborn vitamin K1 prophylaxis is not practiced routinely in India. This study determined the coverage of vitamin K1 prophylaxis among newborns in the country. DESIGN Nationwide cross-sectional data on live births and newborns receiving vitamin K1 during the 2019-2020 reporting period were abstracted from the Health Management Information System (HMIS). The coverage estimates of newborn vitamin K1 prophylaxis were derived nationally and also for individual states and union territories (UT). Additionally, coverage heterogeneities were investigated using classifiers, viz. geography, socio-demographic index (SDI), special developmental categories and institutional birth rate (IBR). SETTING India. PARTICIPANTS 20 208 804 newborns documented with HMIS. RESULTS Vitamin K1 was administered to overall 62·36 % newborns (95 % CI: 62·34 to 62·38 %). The Central zone (49·0 %), low SDI states (54·39 %), Empowered Action Group states (53·32 %) and states with low IBR (44·69 %) had the lowest coverage amongst their respective groupings. Across the individual states and UT, the coverage ranged widely from 22·18 % (in Tripura) to 99·38 % (in Puducherry), exhibiting considerable variability (coefficient of variation: 33·74 %) and inequality (Gini coefficient: 0·17). While the coverage in eight states/UT (i.e. Arunachal Pradesh, Manipur, Nagaland, Tripura, Uttar Pradesh, Uttarakhand, Telangana and Andaman & Nicobar Islands) was below 50 %; only five states/UT (i.e. Chandigarh, Gujarat, Goa, Puducherry and Tamil Nadu) achieved above 90 % coverage. CONCLUSION Vitamin K1 prophylaxis was not practiced in more than one-third newborns in India. It calls for identifying the barriers, addressing the gaps and implementing newborn vitamin K1 prophylaxis more effectively throughout the country.

Intracranial hemorrhage secondary to vitamin K deficiency in X-linked myotubular myopathy. Neuromuscul Disord 2021; 31:651-655. [PMID: 34120822 DOI: 10.1016/j.nmd.2021.04.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 04/05/2021] [Accepted: 04/29/2021] [Indexed: 11/16/2022]
Abstract
X-linked myotubular myopathy (XLMTM) is a rare congenital myopathy characterized by profound hypotonia and poor respiratory effort at birth. The condition is associated with multiple morbidities including chronic respiratory insufficiency, feeding tube dependence, and rarely, vitamin K deficiency leading to bleeding and coagulopathy. We report a case of a 6-month-old boy with X-linked myotubular myopathy who experienced a fatal intracranial hemorrhage due to vitamin K deficiency without prior clinical evidence of cholestasis or micronutrient deficiency. We propose clinically non-apparent cholestasis in combination with acute illness and poor weight gain led to his vitamin K deficiency and intracranial hemorrhage. However, the etiology and mechanism of his cholestasis remains unclear. We conclude that children with X-linked myotubular myopathy, especially with gene therapy on the horizon, may benefit from routine hepatic, coagulation, and nutritional screening to prevent potentially catastrophic bleeding.

Abstract
Symptomatic coagulopathies in celiac disease (CD) are rare. Here, we report a profound case of coagulopathy in a celiac. A 66-year old female without liver disease or anti-coagulation therapy presented with multiple ecchymoses, guaiac positive melanic stool, and a recent 4.5kg weight loss. Laboratory values included hemoglobin, 3.8g/dL; MCV, 66 fL; serum iron, 17μg/dL; platelet count, 580K/μL; white count, 14.2K/μL, and vitamin D,<5.0ng/mL. Additional values included partial thromboplastin time (PTT), >200s; prothrombin time (PT), >150s; INR, 20.5, putting her at extreme risk of bleeding. Vitamin K deficiency was assumed. The patient was given two units of fresh frozen plasma, packed red cells, and vitamin K intravenously. Endoscopy and biopsies demonstrated duodenal mucosal atrophy with cobblestoning, erosive gastritis, flattened duodenal villi and numerous intraepithelial lymphocytes. Transglutaminase serology demonstrated IgA TTG>100 U/mL (normal<3U/mL), confirming a diagnosis of CD. The patient's coagulopathy resolved within two days following admission. This case underscores the importance of CD testing in all patients with coagulopathies of unknown origin. Although coagulopathy is an uncommon presentation of CD, in extreme cases such as this, it has the potential to be life-threatening.

Abstract
Infection with Helicobacter pylori causes chronic inflammation and is a risk factor for gastric cancer. Antibiotic treatment or increased dietary folate prevents gastric carcinogenesis in male INS-GAS mice. To determine potential synergistic effects, H. pylori-infected male INS-GAS mice were fed an amino acid defined (AAD) diet with increased folate and were treated with antibiotics after 18 weeks of H. pylori infection. Antibiotic therapy decreased gastric pathology, but dietary folate had no effect. However, the combination of antibiotics and the AAD diet induced anemia, gastric hemorrhage, and mortality. Clinical presentation suggested hypovitaminosis K potentially caused by dietary deficiency and dysbiosis. Based on current dietary guidelines, the AAD diet was deficient in vitamin K. Phylloquinone administered subcutaneously and via a reformulated diet led to clinical improvement with no subsequent mortalities and increased hepatic vitamin K levels. We characterized the microbiome and menaquinone profiles of antibiotic-treated and antibiotic-free mice. Antibiotic treatment decreased the abundance of menaquinone producers within orders Bacteroidales and Verrucomicrobiales. PICRUSt predicted decreases in canonical menaquinone biosynthesis genes, menA and menD. Reduction of menA from Akkermansia muciniphila, Bacteroides uniformis, and Muribaculum intestinale were confirmed in antibiotic-treated mice. The fecal menaquinone profile of antibiotic-treated mice had reduced MK5 and MK6 and increased MK7 and MK11 compared to antibiotic-free mice. Loss of menaquinone-producing microbes due to antibiotics altered the enteric production of vitamin K. This study highlights the role of diet and the microbiome in maintaining vitamin K homeostasis.

Vitamin K deficiency-induced hemorrhagic shock after thoracentesis: a case report. BMC Gastroenterol 2019; 19:58.

Abstract
BACKGROUND Vitamin K deficiency results in serious coagulation dysfunction, but hemorrhagic shock is rare. Herein, we describe a case of vitamin K deficiency and abnormality in the path of the intercostal artery, the combination of which led to hemorrhagic shock. CASE PRESENTATION An 83-year-old woman was hospitalized for suspected gallstones. She developed septic shock after 4 days of hospitalization. We considered cholecystitis or cholangitis and performed abdominal ultrasonography, which revealed gallbladder enlargement, biliary sludge, and hyperplasia of the bile duct wall. Antibiotic treatment with sulbactam/ampicillin (SBT/ABPC) was initiated on day four, and percutaneous transhepatic gallbladder drainage (PTGBD) was performed on day five. The treatment was successful, but the patient developed bilateral pleural effusion because of hypoalbuminemia. We performed drainage for bilateral pleural effusion on days 13 and 17. The patient developed hypotension on day 18; blood tests showed anemia and severe coagulation dysfunction but a normal platelet count. We suspected vitamin K deficiency-induced coagulation dysfunction because of previous antibiotic treatment and restricted diet, and it led to hemorrhagic shock. Massive right hemothorax was observed by computed tomography, and urgent interventional radiology was performed. We observed no injury to the intercostal artery truncus but confirmed an abnormality in the course of the intercostal artery; therefore, we inferred that the cause of hemothorax in this case was injury to a small vessel, not truncus because of the abnormality. Because of the likelihood of rebleeding, we performed coil embolization from the seventh to the ninth intercostal artery. Because we confirmed vitamin K deficiency-induced coagulation dysfunction, we referred to the concentration of protein induced by vitamin K absence/antagonist-II (PIVKA-II), and it was found to increase by 23,000. CONCLUSIONS A combination of vitamin K deficiency and abnormality in the course of the intercostal artery led to hemorrhagic shock. When using certain antibiotics and restricting diet, it is important to measure coagulation function, even if the platelet count is normal. Further, when thoracentesis is performed, abnormalities in the course of the intercostal artery should be identified. Thoracentesis with ultrasound may prevent hemothorax.

Abstract
BACKGROUND Patients with extensive burns usually develop pro-coagulation soon after the injury if there is no sepsis occurred. We describe the case of an extensive burn adult suffering from hypocoagulation not related to sepsis, but secondary to antibiotic treatment. CASE PRESENTATION Here, we report a case of an adult male patient suffering from flame burns of 45% total body surface area (40% full thickness) combined with inhalation injury. Hypocoagulopathy with soaring prolonged activated partial thromboplastin time value occurred on third week post-burn while systemic infection had been under control by application of broad-spectrum antibiotics. Investigations showed that not the infection but vitamin K-related coagulation factor deficiency were responsible for unexpected bleeding. However, supplemental vitamin K was not the key as we expected, which prompted us trying to decode the underlying cause of coagulation disturbance in this patient and pick out the most effective treatment for live-saving. After the withdrawal of highly suspected broad-spectrum antibiotic, Meropenem®, disturbed vitamin K related coagulation factors gradually restored to their optimal levels so as to maintain normal coagulation status. Therefore, surgical procedures without further risk of bleeding could be carried out in time for wound recovery. The patient was discharged on post-burn day 67 and transferred to a secondary hospital for his rehabilitation. CONCLUSION Hypocoagulopathy may be devoted to different reasons other than sepsis in extensive burns. Early recognition of the cause for coagulation disturbance is critical to make appropriate treatment and save patients' lives. This case illustrated the importance of unveiling the mist cause for coagulation disturbance occurred in extensive burn patient, which paved the way for optimal life-saving treatments. And we also recommend burn surgeons to be alerted to antibiotic-induced vitamin K deficiency-related coagulopathy among critical burn patients.

Abstract
Dietary Vitamin K is a well-known anti-hemorrhagic agent that plays an integral role in the coagulation pathway. Vitamin K is involved in synthesis of coagulation factors; II, VII, IX and factor X. Vitamin K deficiency leads to bleeding diathesis. Hemorrhages usually present in deep soft tissue, rather than mucosal or epithelial membranes, bleeding that is generally caused by disorders of platelets. Major causes of vitamin K deficiency include; medications and diseases involving fat metabolism with a resultant fat malabsorption. Warfarin and Cephalosporins are one of the commonly prescribed medications that lead to vitamin K deficiency. Disease affecting fat metabolism pathway, such as; diseases of the pancreas (cystic fibrosis), short gut syndrome and certain pathologies of the biliary tree. Vitamin K deficiency is more common in newborns. In adults it is uncommon because of its ubiquitous nature and the abundance of its sources. Hemorrhagic disorders in adults due to Vitamin K deficiency are not commonly encountered in practice. We are presenting a case of an adult who presented with a compartment syndrome secondary to a traumatic intramuscular bleeding. Our case highlights the importance of considering vitamin K deficiency in the differential diagnosis of unexplained hemorrhages resulting from a coagulopathy.

Abstract
We present here a late preterm infant with extensive brain lesions resulting from vitamin K deficiency. A female infant was born after 35 weeks of gestation by emergent cesarean section because of non-reassuring fetal status. Her mother had severe eating disorder and recurrent vomiting since early pregnancy. She was immediately intubated and ventilated because she was extremely pale, hypotonic, and non-reactive. Cerebral magnetic resonance imaging immediately after birth showed intraparenchymal hemorrhage in the left frontal lobe and cerebellum, marked cerebral edema, and cerebellar hypoplasia. Coagulation studies of the infant showed hepaplastin test <5%, prolonged PT and APTT, and a marked elevation of protein induced by vitamin K absence or antagonist-II. This case highlighted a potential risk of intracranial bleeding due to maternal vitamin K deficiency and difficulty in its prediction before delivery. Vitamin K supplementation to high risk mothers might be indispensable for preventing severe fetal vitamin K deficiency. Even when coagulation studies in mothers is normal, it is imperative to provide vitamin K supplementation for total protection.

Abstract
BACKGROUND Vitamin K is a cofactor for proteins involved in cardiovascular health, bone metabolism and cancer. Measuring uncarboxylated prothrombin, also termed as "protein induced by vitamin K absence or antagonism for factor II (PIVKA-II)", has been used to assess vitamin K status. High levels may indicate vitamin K deficiency. The aim of this study was to measure PIVKA-II and prothrombin time (PT-INR) in intensive care (ICU) patients and correlate vitamin K status with mortality. METHODS Ninety-five patients admitted to the ICU had blood samples taken near admission and every third day. In addition to PIVKA-II and PT-INR, critical-care severity scores were computed. RESULTS The median baseline PIVKA-II was 4.97 μg/L compared to the upper reference of 2.0 μg/L. PIVKA-II further increased at days 3 and 6, (median 7.88 μg/L, p = .047 and median 8.14 μg/L, p = .011) predominantly in cardiac arrest patients (median 21.4 μg/L, day 3). CONCLUSION Intensive care patients have increased PIVKA-II levels at admission, which increases during the ICU stay, especially in cardiac arrest patients. There were no correlations between PIVKA-II and PT-INR, SOFA score or mortality. Further studies are needed to determine why PIVKA-II increases and whether high PIVKA-II levels in ICU patients affect long-term mortality or morbidity.

Abstract
Background To evaluate the hazard of prolonged antibiotic therapy and/or persistent diarrhea on vitamin K1 (VK1) level and bleeding profile in infants (2–24 weeks). Methods A one-year case-control study, conducted at Ain Shams University, Egypt. 338 infants (2–24 weeks) were recruited and divided into 3 groups (1:1:3 ratios); group A (n=67) patients who received antibiotics for ≥10 days, group B (n=67) who had persistent diarrhea ≥ 14 days and group C (n=204) age- and gender- matched infants who had not either received antibiotics nor had diarrhea. All subjected to clinical assessment, bleeding history and had their complete blood count (CBC), PT and PTT, liver transaminases and VK1 level assayed. Results There was a significant increase in frequency of VKDB (vitamin K deficiency bleeding) and abnormal bleeding profile in cases than control group. There was significant negative correlation between VK1 level and duration of diarrhea, length of antibiotics used and bleeding profile. Antibiotic usage has hazardous effect on VK1 level in those with diarrhea; more patients were receiving antibiotic in those with persistent diarrhea and VKDB (N=55) than those with persistent diarrhea and normal VK1 (N=12). The longer duration of antibiotic therapy the lower level of VK1. Combining cephalosporin/penicillin therapy and/or diarrhea, in particular, had an impact on VK1 level. Conclusion VKDB, a preventable cause of life-threatening hemorrhage, is still a major health problem in Egyptian infants, where persistent diarrhea and misuse of antibiotics are prevalent, necessitate a booster dose of VK in those high risk infants.

Hypoprothrombinemia and severe perioperative haemorrhagic complications in cardiac surgery patients treated with high-dose cefazolin for infective endocarditis. Anaesth Crit Care Pain Med 2017; 37:167-170. [PMID: 28870850 DOI: 10.1016/j.accpm.2017.07.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2017] [Revised: 05/24/2017] [Accepted: 07/11/2017] [Indexed: 10/18/2022]
Abstract
Endocarditis is a serious and common disease that requires prolonged antimicrobial therapy. The recent shortage of oxacillin has led to the use of other antimicrobial agents such as cefazolin to treat endocarditis due to methicillin-sensitive Staphylococcus aureus. We describe four cases of life-threatening haemorrhagic complications (fatal in two cases) in patients treated with high-dose cefazolin. All of these patients with major bleeding presented with hypoprothrombinemia secondary to hypovitaminosis K. This adverse event may be due to inhibition of vitamin K epoxide reductase and/or gamma-glutamyl-carboxylase by the 2-methyl-1,2,3-thiadiazol-5-thiol group of cefazolin. This inhibition may result in hypoprothrombinemia by altering the synthesis of vitamin K-dependent coagulation factors. The increasing use of cefazolin, especially at a high dose and for a prolonged period of time, should be accompanied by regular monitoring of coagulation, including prothrombin index, and vitamin K supplementation.

Hemorrhagic diathesis as the presenting symptom of neonatal cholestasis. Pediatr Gastroenterol Hepatol Nutr 2014; 17:191-5. [PMID: 25349836 PMCID: PMC4209325 DOI: 10.5223/pghn.2014.17.3.191] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2014] [Revised: 08/13/2014] [Accepted: 08/23/2014] [Indexed: 11/14/2022] Open
Abstract
A 4-week-old infant presented with a coagulation disorder resulting from a vitamin K deficiency. The vitamin K deficiency was caused by neonatal cholestasis due to biliary atresia. Jaundice, hepatomegaly and pale stools are the predominant presenting symptoms of biliary atresia, none of which were recognized in our patient before admission. However, the patient presented with bleeding caused by vitamin K deficiency. She was fully breastfed and had received adequate doses of vitamin K at birth and from the age of 1 week. In case of a hemorrhagic diathesis due to neonatal cholestasis, timely identification of treatable underlying disorders, in particular biliary atresia, is important because an early surgical intervention results in a better prognosis. Meticulous history taking and a thorough physical exam can be decisive for an early diagnosis and subsequent intervention.

Abstract
OBJECTIVE Although the connection between cholestasis and conjugated hyperbilirubinemia is well known, mild hepatic dysfunction or cholestasis may also be associated with unconjugated hyperbilirubinemia in some infants with prolonged jaundice. The aim of this study was to investigate the relationship between serum bilirubin levels and alanine aminotransferase levels, asparte aminotransferase levels, prothrombin time, activated partial thromboplastin time and international normalization ratio findings in a group of infants. METHODS The study included 77 healthy, term, breast-fed infants with jaundice and 56 age-matched, healthy, term, non-jaundiced controls. The 133 babies were divided into three subgroups according to their total bilirubin levels [group I (controls) <50 μmol/L, group II=50-100 μmol/L, and group III >100 μmol/L, and the findings for the noted parameters were compared]. RESULTS The mean conjugated bilirubin level was significantly higher, and the mean activated partial thromboplastin time significantly longer in group III than in group I. A significant positive correlation was found between bilrubin levels and PT and APTT results. CONCLUSION Clinical vitamin K deficiency appeared unlikely to develop in this group of infants with prolonged unconjugated hyperbilirubinemia. However, a significant positive correlation between bilirubin levels and PT and APTT suggest that a higher bilirubin load to the liver may cause some degree of vitamin K deficiency due to mild cholestasis. The importance of this finding, and the possible benefits of vitamin K supplementation in 1-month-old breast-fed infants with bilirubin levels higher than 100 μmol/L require further investigation.

Canadian Paediatric Surveillance Program confirms low incidence of hemorrhagic disease of the newborn in Canada. Paediatr Child Health 2004; 9:235-8.

Abstract
OBJECTIVES To determine the incidence of hemorrhagic disease of the newborn (HDNB) in Canada and its relationship to the administration of vitamin K(1) (hereafter referred to as vitamin K) following birth. METHODS The Canadian Paediatric Surveillance Program sent monthly surveys to over 2100 Canadian paediatricians requesting identification of infants with defined criteria for HDNB. Reports were confirmed with subsequent case-specific data, including coagulation test results. RESULTS Of the 26 reports (10 in 1997, eight in 1998, four in 1999, four in 2000), two were from before the start of the study, three were duplicate reports, four cases erroneously identified hemolytic disease of the newborn, three had coagulation studies which were normal or not done, and seven had other disorders with bleeding. Of the six confirmed cases of infants with HDNB (one classic, five late), all had intracranial bleeding and five suffered neurological sequelae. The estimated incidence of HDNB in Canada (including infants who had oral vitamin K prophylaxis or did not receive vitamin K) is approximately 0.45/100,000. CONCLUSION This study confirmed the relatively low incidence of HDNB in Canada and validated the Canadian Paediatric Society's recommendation that all newborns should be given intramuscular vitamin K shortly following birth. To alleviate confusion with haemolytic disease of the newborn, Britain and Australia modified the title of their subsequent HDNB study to vitamin K deficiency bleeding.
