נוגד קרישה זאבתי (Lupus anticoagulant) הוא כינוי לנוגדנים הגורמים להארכה של תבחיני קרישה, התלויים בפוספוליפידים. נוגדנים אלה נחשבים כגורמי סיכון לאירועי פקקת ולסיבוכי הריון הקשורים לתסמונת נוגדנים נגד פוספוליפידים.

תסמונת נוגדנים נגד פוספוליפידים היא תסמונת קלינית המבוססת על שילוב של אירוע פקקת בווריד או בעורק או\ו על סיבוכי הריון – בעיקר הפלות נשנות, והיא מאובחנת בבדיקת מעבדה.  אבחון המעבדה מתבסס על נוכחות נוגד קרישה זאבתי, נוגדנים כנגד קרדיוליפין ו/או נוגדנים כנגד b2 Glycoprotein I בשתי לקיחות דם, המרוחקות זו מזו בזמן של 12 שבועות לפחות.

למרות שאבחון מעבדה של נוכחות LAC נמצא בהתאמה הטובה ביותר עם אירועי פקקת, האבחון בעייתי בהיעדר סטנדרטיזציה בינלאומית.

במאמר זה מדווח על האבחון במעבדה של נוגד קרישה זאבתי, מפורטות הבדיקות המומלצות על ידי תת הוועדה למעבדות הקרישה של האיגוד להמטולוגיה בישראל, מובאות אפשרויות האבחון בחולים המטופלים בנוגדי קרישה, ומפורטת דרך ההתייחסות לתוצאות.

We assessed the prevalence of self-reported medical complaints among the community-dwelling elderly receiving regular medication, and determined associations between health and sociodemographic variables, and the prevalence of complaints.

The study included 170 patients, 60-90 years of age, living at home. Participants were recruited from the 3 main primary care clinics in Rishon LeZion. All were receiving chronic medication and were followed-up utilizing a long-term medication card. Data were gathered in interviews held in patients' homes using a structured questionnaire which included sociodemographics, diseases and medication, mental state assessment by Katzman's score, and a list of 15 medical complaints common among the aged. Relations to age, gender, education, living arrangements, number of diseases and number of medications per patient were determined.

Mean age of participants was 73.2±6.0 years and they suffered an average of 4.07±2.16 diseases and took 5.10±2.83 types of drugs. The most prevalent complaints were: weakness and fatigue (65.0%), agitation and restlessness (56.4%), dry mouth (45.6%), constipation (43.6%) and dizziness (43.2%). The number of diseases, gender, education and age had the strongest associations with the prevalence of specific complaints, as well as their total number. The association between number of medications and mean number of complaints was of borderline significance.

Direct self-referral to a consultant is common in the Israeli health system. Yet patients' reasons for their urgent, unscheduled self-referrals for ambulatory consultations (UUSR) have not been explored. We studied such consultations in an urban multi-disciplinary consultation center serving a population of approximately 100,000. Over a 3-month period such consultations in ophthalmology, ear-nose-and-throat and dermatology clinics were treated by a duty family physician (FP). The FP was instructed to focus on the urgent complaint and either to give definitive treatment and schedule a consultation when needed, or refer the patient for immediate specialist consultation. Patients treated by the FP were asked to fill an anonymous questionnaire, which 347/645 (55.4%) did.

Among the reasons for UUSR were that the patient thought that his/her complaints should be treated by a consultant (29%), the patient was sent by the FP without a consultation note (13.9%), the FP was not available (10.4%), or the patient wished to see the consultant for a second opinion (8.2%). In only 7.8% had the patient noted that his complaint needed urgent consultation. Duration of complaints, but not prior efforts to schedule a consultation, were associated with different reasons for asking for an UUSR. For various reasons patients preferred an UUSR rather than seeing their own FP. Patients' opinions regarding self-referrals are important in planning primary care facilities and FP training.

Abnormal Liver Function Tests in the Primary Care Setting

Results of laboratory tests ordered during a primary care encounter may reveal findings of abnormal liver function tests, including elevated liver enzymes, hyperbilirubinemia, hypoalbuminemia or abnormal coagulation tests. The object of this study was to describe the spectrum of these liver function test (LFT) abnormalities in primary care.

Results of all laboratory tests ordered during 10 months in an urban primary care clinic were retrospectively reviewed and the medical charts of patients with abnormal LFTs were studied. In 217/1088 (20%) of the tests at least 1 LFT abnormality was found in 156 patients. New diagnoses were made in 104 patients. The main diagnostic groups were: non-alcoholic fatty liver changes, Gilbert's disease, acute infectious hepatitis, alcoholic liver disease and cirrhosis and hepatotoxic drug injury. In 60 patients the physician classified the abnormality as negligible and not associated with significant disease. However, an abnormal test that had been ordered for evaluation of a specific complaint, was indeed likely to represent significant disease (X²=29.5, p<0.001). We conclude that finding abnormalities in liver function tests is common in the primary care clinic but does not often indicate significant liver disease.

The use of oral anticoagulant therapy (OAT) to prevent thromboembolism has been widespread in recent years. The concept of high- and low-intensity regimens has facilitated treatment for many, and has lowered the hazards of overly intense anticoagulation. However, a significant proportion of patients suited to the low intensity regimen are not being treated. It is not clear whether its wider use is limited by continued debate, lack of resources, lack of expertise, or other causes. We retrospectively reviewed the medical records of 32 patients treated with OAT administered in the primary care setting. The average age was 66±11 years (range 34-84). 9 were treated with high-intensity OAT: 8 due to artificial heart valves, and 1 due to a hypercoagulable syndrome with recurrent thromboembolism. 23 were treated with low-intensity OAT, 17 of whom had atrial fibrillation. 11 were also being treated continuously with other medication which interacted with OAT or interfered with other coagulation pathways. Such medication included: aspirin, dipyridamole, amiodarone, bezafibrate and allopurinol. Of 414 coagulation tests, 57% and 65% were in the therapeutic range in the high- and low-intensity OAT groups, respectively. There was no major bleeding event, but in 2 of 8 who bled, gastrointestinal bleeding led to hospitalization. Treatment was discontinued in 1 patient because of difficulties in achieving target INR, and in the 2 hospitalized for bleeding. The percentages of test results in, above and below the therapeutic range were similar to those in other large series, for both intensity regimens. We found that a significant proportion of patients were under chronic treatment with other medication which interacted with OAT. To estimate the rate of complications in primary care OAT, larger series are needed. We conclude that OAT can be given and monitored by the family physician, and that awareness of long and short term drug interactions with OAT is mandatory.
