Aneurysm Repair

Introduction Endovascular aneurysm sealing (EVAS) is a sac-filling device with a blunted systemic inflammatory response compared to conventional endovascular aneurysm repair (EVAR), with a suggested impact on all-cause mortality. This study compares mortality after both EVAS and EVAR. Materials and Methods This is a retrospective observational study including data from 2 centres, with ethical approval. Elective procedures on asymptomatic infrarenal aneurysms performed between January 2011 until April 2018 were enrolled. Laboratory values (serum creatinine, haemoglobin, white blood cell count, platelet count) were measured pre- and postoperatively and at 1 and 2 years, respectively. Mortality and cause of death were recorded during follow-up. Results A total of 564 patients were included (225 EVAS, 369 EVAR), after propensity score matching there were 207 patients in both groups. Baseline characteristics were similar, except for larger neck angulation and more pulmonary disease in the EVAR group. The median follow-up time was 49 (EVAS) and 44 (EVAR) months. No significant differences regarding creatinine and haemoglobin were observed. Preoperative white blood cell count was higher in the EVAR group (p=0.011), without significant differences during follow-up. Median platelet count was lower in the EVAR group preoperatively (p=0.001), but was significantly higher at 1 year follow-up (p=0.003). There were 43 deaths within the EVAS group (20.8%) and 52 within the EVAR group (25.1%) (p=0.293). Of these, 4 were aneurysm related (EVAS n=3, EVAR n=1; p=0.222) and 14 cardiovascular (EVAS n=6, EVAR n=8, p=0.845). For the EVAS cohort, survival was 95.5% at 1 year and 74.9% at 5 years. For the EVAR cohort, this was 93.3% at 1 year and 75.5% at 5 years. No significant differences were observed in causes of death. Conclusion This study showed comparable survival rates through 5 years between EVAS and EVAR with a tendency toward higher inflammatory response in the EVAR patients through the first 2 years.

Reactive Thrombocytosis

Abstract Background Enoxaparin is an anticoagulant that falls in the class of medications called low molecular weight heparins (LMWHs), and is used to prevent or treat patients with deep vein thrombosis (DVT) and pulmonary embolism. Enoxaparin is the most widely used LMWH for DVT prophylaxis following knee or hip replacement surgery. Common side effects of enoxaparin include bleeding, petechiae at the injection site, and thrombocytopenia. However, reactive thrombocytosis is a rarely reported adverse reaction. We managed a patient who developed enoxaparin-associated thrombocytosis, which was completely resolved after treatment cessation. Case presentation A 78-year-old female was hospitalized for post-hip replacement rehabilitation. Low molecular weight heparin 40 mg/day was administered subcutaneously to prevent deep venous thrombosis (DVT). At admission, her platelet count was normal (228 × 109/L) and her white blood cell count was slightly elevated (12.91 × 109/L). Seven days after admission, the patient developed thrombocytosis, which peaked on the 14th day (836 × 109/L), while her white blood cell count had returned to normal (8.86 × 109/L). Her therapeutic regimen was reviewed, and enoxaparin was identified as a potentially reversible cause of reactive thrombocytosis. Switching from enoxaparin to rivaroxaban lead to a gradual decrease in the patient’s platelet count, which eventually returned to normal levels 16 days after enoxaparin was discontinued. No complications secondary to thrombocytosis was observed, and no conclusion was reached on the use of small doses of aspirin for antithrombotic therapy under these circumstances. Conclusion Enoxaparin-induced reactive thrombocytosis should be suspected in patients with thrombocytosis following enoxaparin administration as an anticoagulant to prevent certain complications.

IntroductionSplenectomy-induced thrombocytosis and leukocytosis may obscure the early diagnosis of post-operative infection or sepsis. In trauma patients after splenectomy, a platelet-to-white blood cell ratio of <20 has been shown to reliably differentiate post-operative sepsis from transient physiological responses.ObjectiveTo determine whether the platelet-to-white blood cell ratio can be applied to differentiate between reactive post-operative changes and latent infection.MethodsAll consecutive patients with ovarian cancer who underwent splenectomy between January 2013 and October 2018 in two large European gynecological cancer centers were retrospectively evaluated. Main outcome measures were white blood cell count, platelet count, and platelet-to-white blood cell ratio on post-operative days 1, 5, and 7. These were correlated with surgical outcome and morbidity according to the Clavien-Dindo classification. A binomial logistic regression was applied to assess the predictive value of day 5 platelet-to-white blood cell ratio, white blood cell count, and platelet count for predicting grade III post-operative sepsis.ResultsNinety-five patients with ovarian cancer (mean age 54 years, range 18–75) were identified. Seventeen patients (17.9%) developed a grade III post-operative sepsis. In all post-operative patients, mean white blood cell count on day 5 decreased (from 15.4×103/μL to 11.4×103/μL), while the mean platelet count rose (from 260.7×103/μL to 385.3×103/μL). A high platelet count (>313×103/μL) failed to show any predictive value (OR=0.94; 95% CI 0.30 to 3.0; p=0.921). A low platelet-to-white blood cell ratio (<26) (OR=3.49; 95% CI 1.18 to 10.32; p=0.0241) and high white blood cell count (>14.5×103/μL) on day 5 (OR=11.0; 95% CI 3.3 to 36.2; p<0.001) were significant for predicting sepsis. Despite a significant OR, the sensitivity and specificity were low; day 5 platelet-to-white blood cell ratio at a cut-off point of 26 achieved a sensitivity of 72% and specificity of 53% (area under the curve 0.637, 95% CI 0.480 to 0.796) in predicting grade III post-operative sepsis.ConclusionsPlatelet-to-white blood cell ratio after cytoreductive surgery for ovarian cancer with splenectomy does not appear to have a strong predictive value in differentiating between sepsis and reactive splenectomy-induced changes. Leukocytosis, in combination with clinical assessment, may remain the most useful tool for prediction of sepsis after cytoreductive surgery with splenectomy.

Abstract A definition of response by cytoreductive therapy in essential thrombocythemia was recently provided by the European LeukemiaNet (ELN). Complete, partial, or no clinicohematologic responses were defined on the bases of platelet count, disease-related symptoms, spleen size, and white blood cell count. To provide estimates and clinical correlation of responses according to these criteria, we retrospectively examined 416 essential thrombocythemia patients treated with hydroxyurea for at least 12 months. Complete response, partial response, and no response were 25%, 58%, and 17%, respectively. Age more than 60 years and JAK2V617F mutation were significant predictors of response. After a median follow-up of 3.9 years, we registered 23 deaths, 16 hematologic transformations, and 27 thrombotic events (rate, 1.66% patients/year). Age, previous thrombosis, leukocytosis (white blood cell count > 10 × 109/L), but not ELN responses, were independently associated with higher risk of thrombosis. The actuarial probability of thrombosis was significantly influenced by leukocytosis (P = .017) and not by platelet count, indicating that platelet number does not seem of prime relevance in the definition of ELN response.

Histologic Response

European experts were convened to develop a definition of response to treatment in polycythemia vera (PV) and essential thrombocythemia (ET). Clinicohematologic (CH), molecular, and histologic response categories were selected. In ET, CH complete response (CR) was: platelet count less than or equal to 400 × 109/L, no disease-related symptoms, normal spleen size, and white blood cell count less than or equal to 10 × 109/L. Platelet count less than or equal to 600 × 109/L or a decrease greater than 50% was partial response (PR). In PV, CH-CR was: hematocrit less than 45% without phlebotomy, platelet count less than or equal to 400 × 109/L, white blood cell count less than or equal to 10 × 109/L, and no disease-related symptoms. A hematocrit less than 45% without phlebotomy or response in 3 or more of the other criteria was defined as PR. In both ET and in PV, molecular CR was a reduction of any molecular abnormality to undetectable levels. Molecular PR was defined as a reduction more than or equal to 50% in patients with less than 50% mutant allele burden, or a reduction more than or equal to 25% in patients with more than 50% mutant allele burden. Bone marrow histologic response in ET was judged on megakaryocyte hyperplasia while on cellularity and reticulin fibrosis in PV. The combined use of these response definitions should help standardize the design and reporting of clinical studies.

Proporsi perokok pasif di Indonesia mencapai 40,5 persen dan 78,4 persen perokok pasif banyak terpapar asap rokok di dalam rumah.Setiap hembusan asap rokok mengandung 1015 radikal bebas oksidatif dan nikotinpenyebab leukositosis di dalam darah sebagai bentuk respon inflamasi.Jenis leukosit penunjuk inflamasi akibat asap rokok diawali neutrofilia, neutropenia, limfositosis, limfopenia dan monositosis sebagai bentuk respon inflamasi. Analisis deskriptif dengan rancangan cross sectional digunakan untuk memberikan gambaran respon inflamasi ditinjau dari jumlah leukosit dan jenis leukosit pada perokok pasif yang tinggal di kecamatan Pahandut kota Palangka Raya. Sampel yang diperoleh sebanyak 30 orang diambil dengan teknik Purposive Sampling dimulai dengan observasi, pembagian lembar inform consent, wawancara, pengisian kuesioner, pengambilan sampel darah dan pemeriksaan laboratorium menggunakan hematology analyzer dan apusan darah tepi. Data yang diperoleh dimuat dalam bentuk tabel dan dianalisis dan dideskripsikan dalam bentuk persentase (%). Pada 5 orang (17%) terjadi leukositosis, 2 orang (6%) neutropenia, 1 orang (3%) neutrofilia, 1 orang (3%) limfopenia, dan 6 orang (20%) limfositosis. Leukositosis menunjukkan penanda adanya perubahan imun sistemik, dimana selanjutnya terjadi rekrutmen sel inflamasi diantaranya neutrofil dan limfosit. Radikal bebas dan nikotin memicu inflamasi ditandai dengan neutrofilia dengan limfopenia relatif pada awal inflamasi dan selanjutnya berkembang menjadi limfositosis dengan neutropenia relatif.Proportion of passive smokers in Indonesia reached 40,5% and 78,4% of them were exposure of cigarette smoke in the house. Each puff of cigarette smoke contains 1015 of oxidative free radicals and nicotine that causes leukocytosis in the blood where it found as an inflammatory response. Either free radicals or nicotine can also cause of neutrophilia, neutropenia, lymphocytosis, lymphopenia, and monocytosis. This study aimed to overview of the inflammatory response in terms of white blood cell count and differential counting of leukocytes in passive smokers (housewives) who live in the district of Pahandut, Palangka Raya. Descriptive analysis with cross sectional design was used in this study. Samples obtained by 30 people were taken with Purposive Sampling technique. Procedure of collecting data starts from observation, distribution of informed consent, interview, answered of questionnaire, blood sampling and laboratory examination using hematology analyzer for measured of white blood cell count and peripheral blood smear for measured of differential counting of leukocytes. The data obtained were analyzed and described in percentage (%). This study found 5 people (17%) of leukocytosis, 2 people (6%) of neutropenia, 1 person (3%) of neutrophilia, 1 person (3%) of lymphopenia, and 6 people (20%) of lymphocytosis. Leukocytosis occurs because of the mechanism of leukocytes recruitment into inflammatory tissues and the types of leukocyte that increased are neutrophils and lymphocytes. Free radicals and nicotine play a major role in triggering inflammation. Acute inflammation cause of exposure of cigarette smoke characterized by neutrophilia and relative lymphopenia in the blood and it will be develop into chronic inflammation that characterized by lymphocytosis and relative neutropenia.
