Inclusion of medication-related fall risk in fall risk assessment tool in geriatric care units.

BACKGROUND: Falls are common undesirable events for older adults in institutions. Even though the patient's fall risk may be scored on admission, the medication-induced fall risk may be ignored. This study developed a preliminary categorization of fall-risk-increasing drugs (FRIDs) to be added as a risk factor to the existing fall risk assessment tool routinely used in geriatric care units. METHODS: Medication use data of older adults who had experienced at least one fall during a hospital ward or a nursing home stay within a 2-year study period were retrospectively collected from patient records. Medicines used were classified into three risk categories (high, moderate and none) according to the fall risk information in statutory summaries of product characteristics (SmPCs). The fall risk categorization incorporated the relative frequency of such adverse drug effects (ADEs) in SmPCs that were known to be connected to fall risk (sedation, orthostatic hypotension, syncope, dizziness, drowsiness, changes in blood pressure or impaired balance). Also, distribution of fall risk scores assessed on admission without considering medications was counted. RESULTS: The fall-experienced patients (n = 188, 128 from the hospital and 60 from nursing home records) used altogether 1748 medicaments, including 216 different active substances. Of the active substances, 102 (47%) were categorized as high risk (category A) for increasing fall risk. Fall-experienced patients (n = 188) received a mean of 3.8 category A medicines (n = 710), 53% (n = 375) of which affected the nervous and 40% (n = 281) the cardiovascular system. Without considering medication-related fall risk, 53% (n = 100) of the patients were scored having a high fall risk (3 or 4 risk scores). CONCLUSION: It was possible to develop a preliminary categorization of FRIDs basing on their adverse drug effect profile in SmPCs and frequency of use in older patients who had experienced at least one documented fall in a geriatric care unit. Even though more than half of the fall-experienced study participants had high fall risk scores on admission, their fall risk might have been underestimated as use of high fall risk medicines was common, even concomitant use. Further studies are needed to develop the FRID categorization and assess its impact on fall risk.

Pancytopenia, panhypopituitarism and liver cirrhosis: analysis of a difficult clinical case.

Panhypopituitarism following craniopharyngioma resection has systemic impact with potential influence on physio-logical hematopoiesis. There is a growing body of evidence of liver fibrosis/cirrhosis risk development due to altered metabolism and lipid accumulation. The authors present a case report of a woman with a history of craniopharyngioma resection followed by aggravating pancytopenia with suspected indolent lymphoproliferative disorder and possible acquired bone marrow aplasia syndrome due to paroxysmal nocturnal hemoglobinuria. A complex hemostasis disorder with deficiency of multiple coagulation factors (FXII, FXI, FX, FIX, FVII, FX, FV, FXIII, antitrombin, protein C, protein S) was accidentally detected. Despite normal sonographic liver imaging, all possible causes of chronic liver disease were systematically excluded (viral hepatitis, hemochromatosis, Wilson´s disease, α-1-antitrypsin deficiency); anti-LKM-1 and anti-ENA antibodies were detected. Finally, the magnetic resonance imaging confirmed image of liver cirrhosis - with signs of portal hypertension.

Antithrombotics today.

Over the last 10 years some new drugs affecting blood clotting - antithrombotics - were invented. For more than half a century only warfarin and heparin were available. A better understanding of the pathways involved in activation of blood clotting, the links between these systems, and the impact of thrombosis on inflammation, have led to identification of new targets and development of new drugs, especially new antiplatelet drugs and anticoagulants. With the advent of new drugs into clinical practice, treatment options of thrombotic complications are expanding. However, it is always necessary to get familiar with the drug and its properties and to know its limitations. This is the only way to offer patients the best practices. Key words: anticoagulant - antithrombotic - Direct Oral AntiCoagulant (DOAC) - laboratory monitoring - Low-Molecu-lar-Weight Heparins (LMWH) - New Oral Anticoagulants/Non-vitamin K Oral AntiCoagulants (NOAC) - unfractionated heparin (UFH) - warfarin.

Well-managed warfarin therapy remains an important method of anticoagulation in the 21st century, despite the introduction of new antithrombotics into the clinical practice. The main advantages of warfarin are decades of treatment experience, the possibility to monitor its anticoagulant effect using the INR and the last, but not least, the low cost. Currently, approximately 75 % of anticoagulated patients in the Czech Republic are treated with warfarin and warfarin remains the only option for oral anticoagulant therapy in certain clinical conditions (particularly in patients with valvular atrial fibrillation or mechanical heart valves). For physicians across specialties it is still indispensable to master the basics of safe and effective warfarin therapy, including the management of treatment complications.Key words: anticoagulant therapy - INR - thrombosis - warfarin.

In recent years the options of anticoagulant/antithrombotic therapy have extended with new - direct oral anticoagulants, comprising direct thrombin inhibitors (dabigatran etexilate) and direct factor Xa inhibitors (rivaroxaban, apixaban). These agents represent another progress towards "the ideal antithrombotic drug", and thus towards a safe and effective antithrombotic therapy. The following article provides actual review and recommendations for clinical practice, including laboratory assessment and management of emergency situations. The approval of idarucizumab as a specific antidote for dabigatran has marked an important step in safety of this treatment.Key words: apixaban - dabigatran - DOAC - NOAC - rivaroxaban.

There are presently new oral anticoagulants (NOAC) for prevention and the treatment of thromboembolic diseases and they are registered in CZ. It concerns of orally direct inhibitors of thrombin (dabigatran etexilate), inhibitors of factor Xa (apixaban, rivaroxaban), respectively, with advantage of some properties not being seen in "classical" anticoagulants. In the use of new anticoagulants, however, are some problems - such as laboratory monitoring in urgent situations of effective treatment and the absence of specific antidote - resolved.
