Continuous glucose monitoring in patients with remission of type 2 diabetes after laparoscopic sleeve gastrectomy without or with duodenojejunal bypass. Clin Obes 2020; 10:e12409. [PMID: 32892484 DOI: 10.1111/cob.12409] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 07/21/2020] [Accepted: 08/08/2020] [Indexed: 01/09/2023]
Abstract
Bariatric surgery is associated with a high remission rate of type 2 diabetes mellitus. However, it is unclear whether patients showing remission of diabetes actually have normal blood glucose levels throughout the day. We therefore performed continuous glucose monitoring (CGM) in 15 ambulatory patients showing remission of diabetes after laparoscopic sleeve gastrectomy (LSG) without or with duodenojejunal bypass (DJB) at the time of diabetic remission (12.9 ± 1.8 months after bariatric surgery). The definition of remission of diabetes was based on the American Diabetes Association criteria. The mean, SD, and coefficient of variation (CV) of glucose calculated from CGM were 6.2 ± 0.6 mmol/L, 1.5 ± 0.4 mmol/L, and 23.7 ± 6.2%, respectively. These values were higher than those of healthy participants without diabetes previously reported. The percentages of time spent above 10.0 mmol/L and below 3.9 mmol/L were 2.6 (IQR 0-5.0)% and 0 (IQR 0-8.0)%, respectively. Thus, patients with remission of diabetes after LSG or LSG/DJB still had substantial periods of hyperglycemia and hypoglycemia throughout the day. Therefore, we must manage patients with diabetes carefully, even after apparent remission of type 2 diabetes in response to bariatric surgery.

Vascular resistance of carotid and vertebral arteries is associated with retinal microcirculation measured by laser speckle flowgraphy in patients with type 2 diabetes mellitus. Diabetes Res Clin Pract 2020; 165:108240. [PMID: 32502691 DOI: 10.1016/j.diabres.2020.108240] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 03/01/2020] [Accepted: 05/21/2020] [Indexed: 01/31/2023]
Abstract
AIMS Evaluation of the retinal microcirculation is key to understanding retinal vasculopathies, such as diabetic retinopathy. Laser speckle flowgraphy (LSFG) has recently enabled us to directly evaluate the vascular resistance in both retinal vessels and capillaries, non-invasively. We therefore assessed whether retinal vessel blood flow and/or the capillary microcirculation are associated with blood flow in the cervical arteries in diabetic patients without severe retinopathy. METHODS We enrolled 110 type 2 diabetes patients, with no or mild non-proliferative diabetic retinopathy, in this prospective cross-sectional study. We measured the resistivity indices (RIs) of the retinal vessel and capillaries by LSFG and those of cervical arteries by Doppler ultrasonography, followed by analyzing associations. RESULTS The RIs of not only the carotid but also vertebral arteries were associated with those of retinal vessel blood flow and the retinal capillary microcirculation. Multiple regression analyses revealed these associations to be independent of other explanatory variables including age and diabetes duration. CONCLUSIONS We obtained novel and direct evidence demonstrating a close association between the retinal microcirculation and cervical artery hemodynamics in diabetic patients. These findings suggest shared mechanisms to underlie micro- and macro-angiopathies. Thus, high vascular resistance of cervical arteries may be a risk of developing retinopathy.

Molecular typing, antibiotic susceptibility, and biofilm production in nonencapsulated Streptococcus pneumoniae isolated from children in Japan. J Infect Chemother 2019; 25:750-757.

Abstract
The prevalence of nonencapsulated Streptococcus pneumoniae (NESp) has increased with the introduction of pneumococcal conjugate vaccines in children; however, the bacteriological characteristics of NESp have not been sufficiently clarified. In this study, NESp strains isolated from the nasopharyngeal carriage of children from four nursery schools in Japan were analyzed for molecular type, antibiotic susceptibility, and biofilm productivity. A total of 152 putative S. pneumoniae strains were identified by optochin-susceptibility analysis, of which 21 were not serotypeable by slide agglutination, quellung reaction, or multiplex PCR. Among these 21 strains, three were lytA-negative and, therefore, not S. pneumoniae. The remaining 18 strains were positive for lytA, ply, pspK, and bile solubility and were confirmed as NESp. Therefore, the isolation rate of NESp in the S. pneumoniae strains in this study was 12.0% (18/149). Molecular-typing analyses classified five strains as two existing sequence types (STs; ST7502 and ST7786), and 13 strains formed four novel STs. Horizontal spread was suspected, because strains with the same ST were often isolated from the same nursery school. The NESp isolates were generally susceptible to most antimicrobials, with the exception of macrolides; however, all isolates possessed more than one abnormal penicillin-binding protein gene. Furthermore, NESp strains were more effective than encapsulated counterparts at forming biofilms, which showed obvious differences in morphology. These data indicated that NESp strains should be continuously monitored as emerging respiratory pathogens.

Abstract
Soft-drink diabetic ketosis, characterized by acute onset ketosis induced by excessive ingestion of sugar-containing drinks, is often seen in obese, young patients, even with undiagnosed type 2 diabetes. We herein report a 15-year-old obese patient with the apolipoprotein E4/2 phenotype, in whom eruptive xanthomas lead to a diagnosis of soft-drink diabetic ketosis. He developed multiple asymptomatic yellowish papules on the auricles, back, buttocks and the extensor surfaces of the elbows and knees. He initially visited a dermatology clinic and his blood triglyceride and HbA1c levels were found to be 6,490 mg/dL and 16.5%, respectively. He was referred to our hospital for treatment of hyperglycemia and hypertyriglyceridemia. On admission, he had ketonuria and increased blood levels of 3-hydroxybutylate and acetoacetate. He habitually drank 1-3 litters of sweet beverages daily to quench his thirst. Therefore, "soft-drink diabetic ketosis" was diagnosed. Severe hypertriglyceridemia was considered to have been a consequence of impaired insulin action and his apolipoprotein E4/2 phenotype. We treated the diabetic ketosis and hypertriglyceridemia with intensive insulin therapy and a fat-restricted diet. At discharge, he no longer required insulin therapy and his blood glucose levels were controlled with metformin and voglibose. Along with amelioration of the hyperglycemia, triglyceride levels decreased to 247 mg/dL without administration of anti-hyperlipidemia agents. The eruptive xanthoma lesions gradually diminished in size and number and eventually disappeared by 12 months. This case provides an instructive example of eruptive xanthomas serving as a sign of severe dysregulation, not only of lipid, but also glucose, metabolism.

The impact of gender on medical visit communication and patient satisfaction within the Japanese primary care context. PATIENT EDUCATION AND COUNSELING 2018; 101:227-232.

Abstract
OBJECTIVE This study was designed to address significant gaps in the predominantly western-centric research literature by examining the influence of gender concordance in medical communication and patient satisfaction within the Japanese context. METHODS New primary care patients (54 male and 49 female) were randomly assigned to study internists (6 males and 5 females). Recorded visits were coded with the Roter Interaction Analysis System (RIAS). Post-visit, patients completed a Japanese version of the Medical Interview Satisfaction Scale (MISS). RESULTS: Female concordant visits showed higher levels of patient-centeredness than all other gender combinations. Female physicians substantially modified their communication based on patient gender while male physicians did not. Gender concordance was associated with higher female, but lower male patient satisfaction relative to gender discordant visits. CONCLUSION Contrary to normative experience of medicine as a male dominated profession in Japan, and gender-based power differentials, male-gendered clinical communication is less likely to satisfy male than female patients, while female-gendered communication is positively associated with female patient satisfaction. PRACTICE IMPLICATIONS Patient satisfaction ratings reflect greater gender flexibility in terms of acceptable physician behavior than Japanese norms would suggest.

Abstract
In order to clarify the association between hyperglycemia during the early period after allogeneic stem cell transplantation (allo-SCT) and adverse outcomes, we retrospectively analyzed 563 consecutive patients who underwent allo-SCT at our institute between 2008 and 2015. Patients were categorized into three groups according to mean fasting blood glucose levels on days 0-7 (normoglycemia group<110 mg/dL, n=347; mild hyperglycemia group 110-149 mg/dL, n=192 and moderate/severe hyperglycemia group≥150 mg/dL, n=24). The median follow-up was 2.7 years. Patients in the moderate/severe hyperglycemia group had significantly worse characteristics. The cumulative incidences of 2-year non-relapse mortality (NRM) and the probabilities of 2-year overall survival (OS) in the normoglycemia, mild hyperglycemia and moderate/severe hyperglycemia groups were 7.5%, 19% and 29%, respectively (P<0.01), and 69%, 53% and 33%, respectively (P<0.01). In multivariate analyses, hyperglycemia was an independent predictor of high NRM (vs normoglycemia; mild hyperglycemia, hazard ratio (HR) 2.56, 95% confidence interval (CI) 1.56-4.18; moderate/severe hyperglycemia, HR 4.46, 95% CI 1.92-10.3) and poor OS (vs normoglycemia; mild hyperglycemia, HR 1.54, 95% CI 1.14-2.07; moderate/severe hyperglycemia, HR 1.61, 95% CI 0.89-2.91). In conclusion, hyperglycemia on days 0-7 after allo-SCT was associated with inferior outcomes.

Abstract
Three guidelines have recently been published for the diagnosis and treatment of disseminated intravascular coagulation (DIC) in adults. This communication seeks to harmonize the recommendations in these guidelines using a modified GRADE system. The scoring system for diagnosis of DIC using global coagulation tests is known to correlate with key clinical observations and outcomes (Moderate quality). The cornerstone of DIC treatment is the treatment of the underlying condition (Moderate quality). In general, transfusion of platelets or plasma (components) in patients with DIC should be reserved for patients who are bleeding (Low quality). Therapeutic doses of heparin should be considered in cases of DIC where clinical features of thrombosis predominate. Heparin is not recommended in those patients with a high risk of bleeding, (Moderate quality). However, prophylactic doses of unfractionated heparin or low molecular we ight heparin is recommended in critically ill and non-bleeding patients with DIC for prevention of venous thromboembolism (Moderate to High quality). Although further prospective evidence from randomized controlled trials is required, administration of antithrombin or recombinant thrombomodulin may be considered in certain patients with DIC. In general, patients with DIC should not be treated with antifibrinolytic agents (Low quality). However those who present with severe bleeding, that is characterized by a markedly hyperfibrinolytic state such as leukemia (Low quality) and trauma (Moderate quality), may be treated with antifibrinolytic agents. © 2013 International Society on Thrombosis and Haemostasis.

Abstract
The concept of "patient enablement" involves patients' perceptions of ability to understand and cope with illness. Improving enablement is an important goal of medical consultations for patients with chronic illness. To measure "enablement," a post-medical-consultation patient-reported questionnaire was developed and named "Patient Enablement Instrument (PEI)" in the United Kingdom. Unfortunately, there has been no tool to evaluate patient enablement in Japan. Therefore, this study aimed to develop PEI Japanese version, to examine its validity and reliability, and to clarify the constitution of concept about patient enablement among Japanese patients. The translation process included forward translation, expert panel back-translation, following the standard WHO process. Participants were 256 individuals (157 men and 99 women; mean age 62.9 ± 11.8 years) receiving a regular outpatient treatment due to chronic illness at the Department of Cardiology, Respiratory, or Endocrinology and Metabolism in a regional hospital. To assess validity, we compared PEI with Medical Interview Satisfaction Scale (MISS) by correlation coefficient, which was 0.55 (P < 0.01). Furthermore, factor analysis indicated that PEI had two principal factors labeled "coping with illness and health maintenance" and "confidence in oneself and independence". For an evaluation of reliability, internal consistency was calculated (Cronbach's alpha = 0.875). In conclusion, two principal factors comprise patient enablement measured by PEI with satisfactory validity and reliability. PEI Japanese version will be a useful tool to evaluate and improve medical consultations in Japan.

Abstract
To clarify the clinical features and outcome of Stenotrophomonas maltophilia infection among hematopoietic SCT (HCT) recipients, we retrospectively reviewed the records of 1085 consecutive HCT recipients and identified 42 episodes in 31 HCT recipients with S. maltophilia infection. We compared these recipients with 30 non-HCT patients with S. maltophilia infection. The mortality rate in HCT recipients was significantly higher than that in non-HCT patients (relative risk 5.7, P=0.04), and we identified seven patients with pulmonary hemorrhage due to S. maltophilia, exclusively in the HCT cohort. Six of these latter seven patients died within 1 day from the onset of hemorrhage and the isolate was identified after death in most cases; one patient, who received empiric therapy for S. maltophilia and granulocyte transfusion, survived for more than 2 weeks. The patients with pulmonary hemorrhage had a more severe and longer duration of neutropenia, persistent fever despite of the use of broad-spectrum antibiotics, complication by pneumonia and higher C-reactive protein levels than those without pulmonary hemorrhage. In conclusion, S. maltophilia was associated with fulminant and fatal pulmonary hemorrhage in HCT recipients. Empiric therapy with antibiotics before the onset of pulmonary hemorrhage may be effective in HCT recipients who carry the conditions identified.

Comparison of actual tidal volume in neonatal lung model volume control ventilation using three ventilators. Anaesth Intensive Care 2011; 39:599-606.

Abstract
In neonates, small changes in tidal volumes (V(T)) may lead to complications. Previous studies have shown a significant difference between ventilator-measured tidal volume and tidal volume delivered (actual V(T)). We evaluated the accuracy of three different ventilators to deliver small V(T) during volume-controlled ventilation. We tested Servo 300, 840 ventilator and Evita 4 Neoflow ventilators with lung models simulating normal and injured neonatal lung compliance models. Gas volume delivered from the ventilator into the test circuit (V(TV)) and actual V(T) to the test lung were measured using Ventrak respiration monitors at set V(T) (30 ml). The gas volume increase of the breathing circuit was then calculated. Tidal volumes of the SV300 and PB840 in both lung models were similar to the set V(T) and the actual tidal volumes in the injured model (20.7 ml and 19.8 ml, respectively) were significantly less than that in the normal model (27.4 ml and 23.4 ml). PB840 with circuit compliance compensation could not improve the actual V(T). V(TV) of the EV4N in the normal and the injured models (37.8 ml and 46.6 ml) were markedly increased compared with set V(T), and actual V(T) were similar to set V(T) in the normal and injured model (30.2 ml and 31.9 ml, respectively). EV4N measuring V(T) close to the lung could match actual V(T) to almost the same value as the set V(T) however the gas volume of the breathing circuit was increased. If an accurate value for the patient's actual V(T) is needed, this V(T) must be measured by a sensor located between the Y-piece and the tracheal tube.

Abstract
In neonates, small changes in tidal volumes (VT) may lead to complications. Previous studies have shown a significant difference between ventilator-measured tidal volume and tidal volume delivered (actual VT). We evaluated the accuracy of three different ventilators to deliver small VT during volume-controlled ventilation. We tested Servo 300, 840 ventilator and Evita 4 Neoflow ventilators with lung models simulating normal and injured neonatal lung compliance models. Gas volume delivered from the ventilator into the test circuit (VTV) and actual VT to the test lung were measured using Ventrak respiration monitors at set VT (30 ml). The gas volume increase of the breathing circuit was then calculated. Tidal volumes of the SV300 and PB840 in both lung models were similar to the set VT and the actual tidal volumes in the injured model (20.7 ml and 19.8 ml, respectively) were significantly less than that in the normal model (27.4 ml and 23.4 ml). PB840 with circuit compliance compensation could not improve the actual VT. VTV of the EV4N in the normal and the injured models (37.8 ml and 46.6 ml) were markedly increased compared with set VT, and actual VT were similar to set VT in the normal and injured model (30.2 ml and 31.9 ml, respectively). EV4N measuring VT close to the lung could match actual VT to almost the same value as the set VT, however the gas volume of the breathing circuit was increased. If an accurate value for the patient's actual VT is needed, this VT must be measured by a sensor located between the Y-piece and the tracheal tube.

Abstract
Primary pulmonary hypertension is a fatal disease that frequently becomes evident in pregnancy. The management of pregnant women with primary pulmonary hypertension poses a number of difficult problems, especially where regional anesthesia is considered to be contraindicated. A 30-year-old woman who developed primary pulmonary hypertension at 23 weeks of pregnancy was transferred to our hospital. Systolic pulmonary artery pressure and plasma brain natriuretic peptide levels were markedly elevated. Nitric oxide inhalation and prostacyclin prevented the progression of cardiac failure and reduced both plasma brain natriuretic peptide and pulmonary artery pressure. Cesarean section was performed at 32 weeks under general anesthesia. A combination of nitric oxide, prostacyclin, nitroglycerin, and dobutamine were administered during surgery. Intravenous dexmedetomidine was specifically used during emergence and recovery from anesthesia. This provided effective pain relief and hemodynamic stability. Throughout the clinical course, brain natriuretic peptide levels was monitored and used as an indicator of cardiac failure.

Abstract
Some studies have shown that intensive glucose control (IGC) improves outcome in the intensive care unit setting. However, it is the benefit of IGC in hematopoietic SCT (HSCT) that is not well defined. Between June 2006 and May 2007, IGC was maintained prospectively after allogeneic HSCT and clinical outcomes were compared with a cohort matched for conditioning regimen, source of stem cells, age and relation to donor. A stratified Cox regression model was used. There were no significant differences in baseline clinical characteristics. The median age was 43.5 years in both groups. The primary diagnosis was a hematologic malignancy. Patients in the IGC group had a lower glucose level (least-square mean, 116.4 vs 146.8 mg per 100 ml, P<0.001) compared to the standard glucose control group. The incidences of documented infections and bacteremia were significantly lower in the IGC group (14 vs 46%, P=0.004, 9 vs 39%, P=0.002, respectively). IGC tended to reduce the incidence of renal dysfunction (19 vs 37%, P=0.36) and the elevation of C-reactive protein (18 vs 38%, P=0.13). This study suggests that IGC has may have a beneficial effect after HSCT. IGC should be evaluated further in a large prospective, randomized study.

Abstract
BACKGROUND AND OBJECTIVES Genes encoding protein C anticoagulant pathways are candidates for atherothrombotic and other aging-related disorders. METHODS Using a tagSNP approach, and data from the Cardiovascular Health Study (CHS), we assessed associations of common polymorphisms of PROC, PROS1 and PROCR with: (i) plasma protein C, soluble protein C endothelial receptor (sEPCR) and protein S levels measured in a subsample of 336 participants at study entry; and (ii) risk of incident clinical outcomes [coronary heart disease (CHD), stroke, and mortality] in 4547 participants during follow-up. Secondarily, we explored associations between plasma protein C, protein S and sEPCR levels and other candidate genes involved in thrombosis, inflammation, and aging. RESULTS The PROCR Ser219Gly polymorphism (rs867186) was strongly associated with higher sEPCR levels, explaining 75% of the phenotypic variation. The PROCR Ser219Gly variant was also associated with higher levels of circulating protein C antigen. An IL10 polymorphism was associated with higher free protein S levels. The minor alleles of PROC rs2069901 and PROS1 rs4857343 were weakly associated with lower protein C and free protein S levels, respectively. There was no association between PROCR Ser219Gly and risk of CHD, stroke, or mortality. The minor allele of another common PROCR tagSNP, rs2069948, was associated with lymphoid PROCR mRNA expression and with increased risk of incident stroke and all-cause mortality, and decreased healthy survival during follow-up. CONCLUSIONS A common PROCR variant may be associated with decreased healthy survival in older adults. Additional studies are warranted to establish the role of PROCR variants in ischemic and aging-related disorders.

Abstract
Recent clinical neuroimaging studies have suggested that morphological brain changes occur and progress in the course of schizophrenia. Although the neurogenetic and neurotrophic effects of antipsychotics are considered to contribute to the prevention of reduction in brain volume, the cellular molecular mechanisms of action of antipsychotics have not yet been elucidated. We examined the effects of antipsychotics on the endoplasmic reticulum (ER) stress-induced damages of neurons and neural stem cells (NSCs) using cultured cells. In the neuronal cultures, the atypical antipsychotic olanzapine protected neurons from thapsigargin (1 microM)-induced injury. It was observed that a low concentration of thapsigargin (10 nM) that did not affect the neuronal survival could reduce neuronal differentiation of cultured NSCs, suggesting a role of ER stress in the differentiation function of NSCs. Treatment with olanzapine increased the neuronal differentiation suppressed by the exposure to thapsigargin (10 nM). The thapsigargin-induced ER chaperones, GRP78, which indicate the ER stress condition of the cell, were decreased by the treatment with the atypical antipsychotics olanzapine and quetiapine but not by the typical antipsychotic haloperidol. These results indicate that the amelioration of ER-stress might be involved in the cellular mechanisms of atypical antipsychotics to produce neuroprotective and neurogenetic actions in neurons and NSCs, suggesting potential roles of these drugs for treatment of schizophrenia.

Abstract
BACKGROUND AND OBJECTIVE Thiopental has been reported to reduce sympathetic tone, however, it is not clear whether change in heart rate variability is associated with depth of anaesthesia. The purpose of the present study was to evaluate changes in heart rate variability at different depths of hypnosis during induction of anaesthesia with thiopental. METHODS We studied 17 ASA I patients scheduled for minor surgery. The depth of hypnosis was monitored by the BIS. Spectral analysis of heart rate variability using a maximum entropy method resulted in a characteristic power spectrum with two main regions, a high frequency and a low frequency. Haemodynamics, entropy, low frequency, high frequency and low frequency/high frequency were monitored in an awake state and after the induction of anaesthesia. RESULTS Heart rate increased in a BIS-dependent manner, whereas blood pressure showed no significant changes during the study period. High frequency, entropy and low frequency decreased with a reduction in the BIS value. Low frequency/high frequency showed no significant change during the study period. CONCLUSIONS Induction of anaesthesia with thiopental increased heart rate and decreased high frequency, entropy and low frequency in a BIS-dependent manner, indicating that thiopental reduces cardiac parasympathetic tone depending on the depth of hypnosis.

EPCR Ser219Gly: elevated sEPCR, prothrombin F1+2, risk for coronary heart disease, and increased sEPCR shedding in vitro. Atherosclerosis 2006; 183:283-92.

Abstract
We have progressively analysed three studies of coronary heart disease (CHD) for a variant in EPCR (Ser219Gly). Initially, in a prospective study, NPHSII, while no overall CHD-risk was identified in heterozygotes, homozygotes for 219Gly exhibited a three-fold elevated risk (HR 3.3, CI 1.22-8.96). In diabetics within NPHSII, there was a suggestion that 219Gly+ was associated with elevated CHD-risk (HR 1.89, CI 0.39-9.06) although numbers were small. To further assess the effect of the variant in diabetes, a case-control study of MI, HIFMECH, was used, in which previous analysis had defined a group with metabolic syndrome, by factor analysis. A significant CHD-risk interaction was identified between genotype and the 'metabolic syndrome' factor (interaction p=0.009). To further assess CHD-risk for this variant in type-2 diabetes and to assess the effect of the variant upon thrombin generation and plasma levels of soluble EPCR, a cross-sectional study of type-2 diabetes was used. A significant CHD-risk was identified for European Whites (OR 2.84, CI 1.38-5.85) and Indian Asians in this study (OR 1.6, CI 1.00-2.57) and the frequency of 219Gly was two-fold higher in Indian Asians. Soluble EPCR levels were strongly associated with genotype, with homozygotes for 219Gly having four-fold higher levels (p<0.0001). In vitro studies of EPCR-transfected cells suggested increased basal release of sEPCR from cells expressing the 219Gly EPCR phenotype. Furthermore, in base-line samples from NPHSII and in the diabetic study, a significant increase in prothrombin F1+2 level was observed for 219Gly. The increased CHD-risk and thrombin generation appears to be acting through increased shedding of the Gly allele from the cell surface.

Abstract
The biological activity of the Matsucoccus spp. sex pheromones and diene modified analogs has been tested in forests of Israel and Portugal in order to explore the structure-activity relationship of the pine bast scale pheromone/kairomone system. The response of the adult predatory bugs, Elatophilus hebraicus and E. crassicornis and of the brown lacewing, Hemerobius stigma is more selective than that of the conspecific Matsucoccus males. The removal of the terminal methyl group from the diene terminus of both pheromones 1 and 2 eliminates all kairomonal activity but retains moderate pheromonal activity. Addition of a methyl group to the diene terminus of pheromones 1 and 2 sustains full pheromonal and kairomonal activities of the Elatophilus spp. but eliminates entirely the kairomonal activity of H. stigma. Subtle designed alterations in the structure of the diene group, typical of all Matsucoccus pheromones, change the mode of the kairomonal activity markedly.

Abstract
Elevated soluble thrombomodulin (sTM) levels are an accepted marker of endothelial damage. The physiological significance of plasma endothelial protein C receptor (sEPCR) levels is not known. To assess the relevance of this plasma protein in Wegener's granulomatosis (WG), sEPCR levels were measured in sera obtained from WG patients and related to disease activity, sTM levels, and other known markers of disease activity. In total, 129 sera (37 at active disease, 92 during follow-up) from 31 WG patients were tested. During active disease, eight (22%) and 17 (46%) out of 37 active sera had elevated levels of sEPCR and sTM, respectively (NS); sEPCR (r = 0.39; P = 0.02) and sTM (r = 0.53; P <0.01) levels correlated with disease activity (Birmingham Vasculitis Activity Score). Analysis of longitudinal sera revealed a significant increase in sEPCR (P = 0.01) and sTM (P = 0.04) levels prior to the moment of a relapse. Corrected for renal function, the increase in sEPCR remained significant (P =0.04) whereas sTM did not (NS). Levels of sEPCR correlated with sTM levels (r = 0.32; P < 0.001). Plasma levels of sEPCR respond to changes in the disease in patients with WG.
