RESUMO

OBJECTIVES: Maraviroc (MVC) is a suitable drug for aviraemic subjects on antiretroviral treatment (ART) developing toxicity. Its prescription requires prior tropism testing. It is unknown if proviral DNA genotypic tropism testing is reliable for guiding MVC initiation in aviraemic subjects, so this study was carried out to address this issue. METHODS: PROTEST was a phase 4, prospective, single-arm clinical trial carried out in 24 HIV care centres in Spain. MVC-naïve HIV-1-infected patients with HIV-1 RNA < 50 copies/mL on stable ART during the previous 6 months who required an ART change because of toxicity and who had R5 HIV, as determined by proviral DNA genotypic tropism testing, initiated MVC with two nucleoside reverse transcriptase inhibitors (NRTIs) and were followed for 48 weeks. Virological failure was defined as two consecutive viral load measurements > 50 copies/mL. RESULTS: Tropism results were available for 141 of 175 (80.6%) subjects screened: 60% had R5 and 85% of these (n = 74) were finally included in the study. Previous ART included protease inhibitors (PIs) in 62% of subjects, nonnucleoside reverse transcriptase inhibitors (NNRTIs) in 36%, and integrase inhibitors (INIs) in 2%. Main reasons for treatment change were dyslipidaemia (42%), gastrointestinal symptoms (22%) and liver toxicity (15%). MVC was given alongside tenofovir (TDF)/emtricitabine (FTC) (54%) and abacavir (ABC)/lamivudine (3TC) (40%) in most patients. Eighty-four per cent of patients maintained a viral load < 50 copies/mL to week 48, whereas 16% discontinued treatment: two withdrew informed consent, one had an R5 to X4 shift between screening and baseline, one was lost to follow-up, one developed an adverse event (rash), two died from non-study-related causes, and five developed protocol-defined virological failure. CONCLUSIONS: Initiation of MVC plus two NRTIs in aviraemic subjects based on genotypic tropism testing of proviral HIV-1 DNA is associated with low rates of virological failure for up to 1 year.

RESUMO

In April 2015, the Spanish National Health System (SNHS) developed a national strategic plan for the diagnosis, treatment, and management of hepatitis C virus (HCV). Our aim was to analyze the impact of this on human immunodeficiency virus (HIV)-infected patients included in the HERACLES cohort during the first 6 months of its implementation. The HERACLES cohort (NCT02511496) was set up in March 2015 to evaluate the status and follow-up of chronic HCV infection in patients co-infected with HIV in the south of Spain. In September 2015, the data were analyzed to identify clinical events (death, liver decompensation, and liver fibrosis progression) and rate of treatment implementation in this population. The study population comprised a total of 3474 HIV/HCV co-infected patients. The distribution according to liver fibrosis stage was: 1152 F0-F1 (33.2 %); 513 F2 (14.4 %); 641 F3 (18.2 %); 761 F4 (21.9 %); and 407 whose liver fibrosis was not measured (12.3 %). During follow-up, 248 patients progressed by at least one fibrosis stage [7.1 %; 95 % confidence interval (CI): 6.3-8 %]. Among cirrhotic patients, 52 (6.8 %; 95 % CI: 5.2-8.9 %) developed hepatic decompensation. In the overall population, 50 patients died (1.4 %; 95 % CI: 1.1-1.9 %). Eight hundred and nineteen patients (23.56 %) initiated interferon (IFN)-free treatment during follow-up, of which 47.8 % were cirrhotic. In our study, during 6 months of follow-up, 23.56 % of HIV/HCV co-infected patients included in our cohort received HCV treatment. However, we observed a high incidence of negative short-term outcomes in our population.

RESUMO

We analysed the efficacy and safety of switching from a regimen based on nonnucleoside reverse transcriptase inhibitors (NNRTI) or integrase inhibitors (INI) to ABC/3TC + RPV in virologically suppressed HIV-infected patients. This multicentre, retrospective study comprised asymptomatic HIV-infected patients who switched from 2 NRTI + NNRTI or 2 NRTI + INI to ABC/3TC + RPV between February 2013 and December 2013; all had undetectable HIV viral load prior to switching. Efficacy and safety, and changes in lipids and cardiovascular risk (CVR) were analysed at 48 weeks. Of 85 patients (74.1 % men, mean age 49.5 years), 83 (97.6 %) switched from a regimen based on NNRTI (EFV 74, RPV 5, ETV 2, NVP 2), and 45 (53 %) switched from TDF/FTC to ABC/3TC. The main reasons for switching were toxicity (58.8 %) and convenience (29.4 %). At 48 weeks, 78 (91.8 %) patients continued taking the same regimen; efficacy was 88 % by intention to treat, and 96 % by per protocol. Two patients were lost to follow-up and five ceased the new regimen (4 due to adverse effects and 1 virologic failure). Mean CD4 cell counts increased (744 vs. 885 cells/µL; p = 0.0001), and there were mean decreases in fasting total cholesterol (-15.9 mg/dL; p < 0.0001) and LDL-cholesterol (-11.0 mg/dL; p < 0.004), with no changes in HDL-cholesterol, triglycerides, total cholesterol:HDL-cholesterol ratio, and CVR. ABC/3TC + RPV is effective and safe in virologically-suppressed patients on antiretroviral therapy (ART). Forty-eight weeks after switching the lipid profile improved with decreases in total and LDL cholesterol.

RESUMO

The implementation of hepatitis C (HCV) direct-acting antiviral drugs is prioritized in several populations in which its application provides the most immediate and impactful benefit. In this scenario, a precise knowledge of the situation of human immunodeficiency virus (HIV)/HCV chronic co-infection is required to adequately address this disease. This cross-sectional study was performed in 21 hospitals in Andalusia (Spain). The study population consisted of HIV-infected patients with an active HCV chronic infection who were not receiving HCV treatment at the time of inclusion. A total of 13,506 HIV-infected patients were included in the study. Of them, 2561 (18.9 %) presented chronic HCV infection. The majority of the patients included were on highly active antiretroviral therapy (HAART; 96.2 %), showed plasma levels with an undetectable HIV viral load (92.5 %), and had a good immunological status (median CD4+ cell count of 486 cells/mL). The HCV genotype distribution was as follows: 58.1 % were genotype 1, 1.1 % were genotype 2, 16.1 % were genotype 3, and 22.1 % were genotype 4 (2.6 % were missing data). In total, 24.8 % of the patients showed liver fibrosis stage F0-F1, 27.9 % showed stage F2, 16.7 % showed stage F3, and 21 % showed stage F4 (9.6 % were missing data). With regards to previous HCV treatment experiences, 68.05 % of the patients were naïve and 31.95 % had failed to respond to a previous treatment. The burden of HCV/HIV co-infected patients in our population was reported as one in five HIV-infected patients requiring HCV treatment. The implementation of extra resources to face this important health challenge is mandatory.

RESUMO

PURPOSE: Tuberculous meningitis (TBM) is one of the most serious and difficult to diagnose manifestations of TB. An ADA value >9.5 IU/L has great sensitivity and specificity. However, all available studies have been conducted in areas of high endemicity, so we sought to determine the accuracy of ADA in a low endemicity area. METHODS: This retrospective study included 190 patients (105 men) who had ADA tested in CSF for some reason. Patients were classified as probable/certain TBM or non-TBM based on clinical and Thwaite's criteria. Optimal ADA cutoff was established by ROC curves and a predictive algorithm based on ADA and other CSF biochemical parameters was generated. RESULTS: Eleven patients were classified as probable/certain TBM. In a low endemicity area, the best ADA cutoff was 11.5 IU/L with 91 % sensitivity and 77.7 % specificity. We also developed a predictive algorithm based on the combination of ADA (>11.5 IU/L), glucose (<65 mg/dL) and leukocytes (≥13.5 cell/mm(3)) with increased accuracy (Se: 91 % Sp: 88 %). CONCLUSIONS: Optimal ADA cutoff value in areas of low TB endemicity is higher than previously reported. Our algorithm is more accurate than ADA activity alone with better sensitivity and specificity than previously reported algorithms.

RESUMO

UNLABELLED: Patients with chronic hepatitis C have low bone mineral density and increased bone resorption related to serum transaminase levels. Elevated serum soluble tumor necrosis factor (sTNFR-55) receptor levels may play a role in the bone mass loss in these patients. Bone mass is improved and bone turnover normalized in patients who respond to antiviral therapy with interferon and ribavirin. INTRODUCTION: Low bone mineral density (BMD) has been described in patients with chronic hepatitis C (HCV). The study objective was to evaluate the effect of antiviral therapy on BMD and bone metabolism in non-cirrhotic HCV patients with sustained virological response. METHODS: We conducted a prospective study in 36 consecutive outpatients from the general community with non-cirrhotic HCV and an early and sustained virological response to peginterferon-alfa and ribavirin therapy. Determinations of BMD (dual X-ray absorptiometry at lumbar spine and femoral neck) and biochemical measurements of bone metabolism and sTNFR-55 were made at baseline, after 24 and 48 weeks of antiviral therapy, and at 48 weeks after the end of treatment. RESULTS: Patients had a significantly reduced BMD, which significantly increased during the follow-up. Serum levels of sTNFR-55 and bone turnover markers were increased at baseline and significantly reduced at all subsequent time points. We found an inverse correlation between BMD and both serum aminotransferase levels and urine deoxypyridinoline (D-pyr) and a positive correlation between serum aminotransferases and both urine D-Pyr and serum sTNFR-55. CONCLUSIONS: Patients with chronic hepatitis C have low bone mass associated with increased bone resorption, and some relationship can be expected between serum aminotransferase levels and the degree of bone mass loss. Bone mass may be improved and bone turnover normalized in patients who respond to antiviral therapy. Elevated serum sTRFR-55 levels may play a role in the bone mass loss of these patients.

RESUMO

There is a paucity of data regarding efficacy and safety of concomitant therapy of daptomycin and statins, so we reviewed patients that concomitantly received daptomycin and statins to identify any potential increase in toxicity in our cohort. This retrospective study included all patients that received >6 mg/kg/day of daptomycin along with statins and had efficacy and safety data. Patients on high dose (>6 mg/kg/day) daptomycin therapy that did not received statins served as controls. One hundred four patients were included. Median daptomycin dose was 7.8 mg/kg/day (range 6.5-10.8 mg/kg/day), for a mean duration of therapy of 17 days (range 10-51 days). Thirty-six patients received daptomycin and statins and 68 received only daptomycin. Muscular toxicity defined as CPK levels>1000 UI/L (2.5 times upper normal limit, range of determination 200-400 UI/L) was equally distributed between both groups (3/36, 8% vs 7/68, 10%; p=0.746). Despite biochemical toxicity, we did not find clinical toxicity and daptomycin treatment was completed in all cases. We did not find predictors of increased CPK during daptomycin therapy. Based on our data, concomitant administration of daptomycin and statins is safe and is not associated with an increased risk of rhabdomyolysis.

RESUMO

INTRODUCTION: Postoperative infection is the most common postsurgical oral complication but no double-blind, randomized, placebo-controlled trial has been made yet to assess amoxicillin prophylaxis for oral surgery. The aim of this pilot study was to assess the effectiveness of prophylactic amoxicillin 3g per os versus placebo in the prevention of postoperative oral infections. METHODS AND MATERIALS: A 5-year, multicentric, randomized, double-blind clinical trial was made on healthy patients undergoing complex oral surgery. Final analysis was by intention to treat. RESULTS: The 286 patients were randomly assigned to the amoxicillin or placebo group. After a mean follow-up of two weeks, 11 patients in the control group and three patients in the amoxicillin prophylaxis group developed a postoperative infection (P=0.001 in unilateral test). The hazard ratio was 0.27 [95% CI: 0.07-0.94]. CONCLUSION: Amoxicillin prophylaxis seems to be effective in preventing postoperative infection in complex oral surgery, especially when mandibular third molars and multiple avulsions are involved.

RESUMO

Remote monitoring of health can reduce frequent hospitalisations, diminishing the burden on the healthcare system and cost to the community. Patient monitoring helps identify symptoms associated with diseases or disease-driven disorders, which makes it an essential element of medical diagnoses, clinical interventions, and rehabilitation treatments for severe medical conditions. This monitoring can be expensive and time-consuming and provide an incomplete picture of the state of the patient. In the last decade, there has been a significant increase in the adoption of mobile and wearable devices, along with the introduction of smart textile solutions that offer the possibility of continuous monitoring. These alternatives fuel a technology shift in healthcare, one that involves the continuous tracking and monitoring of individuals. This scoping review examines how mobile, wearable, and textile sensing technology have been permeating healthcare by offering alternate solutions to challenging issues, such as personalised prescriptions or home-based secondary prevention. To do so, we have selected 222 healthcare literature articles published from 2007 to 2019 and reviewed them following the PRISMA process under the schema of a scoping review framework. Overall, our findings show a recent increase in research on mobile sensing technology to address patient monitoring, reflected by 128 articles published in journals and 19 articles in conference proceedings between 2014 and 2019, which represents 57.65% and 8.55% respectively of all included articles.

RESUMO

AIM: To examine the incidence and the prevalence of neonatal hypoxic-ischemic encephalopathy (HIE) in a tertiary Spanish center over a 9-year period, before the implementation of a hypothermia program. METHODS: All infants > or =34 weeks gestation, born between 2000 and 2008 with evidence of perinatal asphyxia and neonatal encephalopathy were identified. HIE was classified as mild, moderate or severe. Joinpoint regression model was used to identify changes in the trends of HIE incidences. RESULTS: A total of 90,963 live infants were born in La Paz Hospital between 2000 and 2008, and 23.3% of them (21.228) were admitted to the Neonatal Unit. In addition, 200 infants were referred from other centers. A total of 110 infants had HIE, of which 90% were inborn. The overall incidence of HIE was 1.088 per 1,000 live births, and the incidence of clinically significant HIE (moderate and severe grades) was 0.49 per 1,000 live births. The incidence of HIE showed a linear downward trend throughout the study period (slope=-5.37; P<0.05). Fifty-two neonates had moderate or severe HIE, this represents a prevalence of 2.42 per 1,000 infants admitted to the Neonatal Unit and means that 5-6 infants a year would have been candidates for therapeutic hypothermia. CONCLUSIONS: Neonatal HIE, and in particular significant HIE, is an infrequent condition. The low prevalence of HIE requires that these infants are referred to regional centers with sufficient experience in the use of therapeutic hypothermia, and in the management of all the medical problems associated with HIE.

RESUMO

Fever of intermediate duration (FID) is a new nosologic entity defined as fever higher than 38 degrees C that has a duration of between 1 and 4 weeks and that after an initial approach has not been diagnosed. It has clinical similarities with fever of unknown origin, but because of characteristic etiologies it requires the term FID. We describe the clinical characteristics and etiology of FID in the south of Spain and create a treatment algorithm. Retrospective study of the medical charts of patients attending at our Service during 2000 and 2005 who had an initial diagnosis of FID and who had a complete follow-up until the resolution of symptoms. Two hundred and thirty-three patients met the inclusion criteria, of whom 164 were men. Median number of days before being referred to our service was 9 (range 2-28). Half of the patients had elevation of transaminases, and CRP and ESR were slightly elevated, 2.8 mg/dl (range 0.1-50) and 16 mm/h (range 1-131) respectively. A final diagnosis was made in 80 patients, with infection with coxiella (32 patients), CMV (16 patients), rickettsial species (11 patients), VEB virus (6 patients), and brucella (5 patients) being the more frequent entities. Doxycycline was the antibiotic most frequently prescribed. Among patients with Q fever, CMV, and rickettsial infection, the majority had abnormal hepatic function, (87%, 93%, and 55% respectively). In FID, a diagnosis is reached in a minority of patients, although the prognosis is excellent in most of them. In our patients the clinical picture of Q fever, CMV, and rickettsial infections included abnormal hepatic function. In addition, these three infections are the most frequently diagnosed so when treating a patient with FID, if elevation of liver enzymes is present patients should start on doxycycline.

RESUMO

OBJECTIVE: To report the experience of peripheral insertion of double-lumen central catheters (PIDLCC) in preterm and term newborn infants and to analyze the technical characteristics of the procedure and any observed complications. STUDY DESIGN: Retrospective review of 61 newborns that had a PIDLCC between 2003 and 2006. The study comprised clinical data analysis, anthropometrics, indications, duration, complications and reasons for withdrawal of the catheters. RESULT: Weight of the patients was <1 kg in 10%, and >2 kg in 75%. Catheters tip placement was as aimed, mostly superior cava vein (SCV), in 65.5%, and subclavian vein in remaining 34.5% and average duration of catheterization was 13.5+/-9.6 and 8.9+/-5.8 days, respectively. Blood sampling through both lumens was possible especially when the tip was at SCV. Reasons for catheter withdrawal were end of indication (45.9%), phlebitis/edema (21.3%), suspected infection (3.2%), accidental withdrawal (3.2%) and rupture of proximal end (3.2%). In three (4.9%) patients, withdrawal was due to serious complications (two cases of pleural leakage of infusion fluid and one breakage of the metallic guide). About 16.3% of the patients died with the catheter still in situ. Infection findings were positive tip culture (14.7%) and catheter-related sepsis (3.2%). CONCLUSION: Insertion of PIDLCC is possible in neonates. The incidence of complications, mostly mechanical, requires careful evaluation of indications, and strict adherence to the procedure of insertion and manipulation.

RESUMO

INTRODUCTION: Anisakis simplex can be a cause of digestive symptoms. Our aim was to evaluate the epidemiological antecedents and immunological data available for a differentiation between patients with anisakidosis and those with other acute abdominal problems. PATIENTS AND METHODS: this is a prospective cohort study involving 134 patients with acute abdominal problems: 52 patients were diagnosed with anisakidosis by means of surgical and pathological findings and/or specific IgE seroconversion against Anisakis simplex (group A), and in 82 patients anisakidosis had been ruled out (group NA: non-anisakidosis). We evaluated the antecedent of raw fish ingestion, the skin prick test, and IgE immunoblotting as diagnostic tools. RESULTS: patients in groups A and NA differ in terms of prior raw fish ingestion (p < 0.0001) and positive SPT (p < 0.0001), with their respective negative predictive values (NPV) being 98.39% (95%CI: 90.17-99.92) and 95.56% (95%CI: 83.64-99.23). Regarding immunoblotting, in 86.2% of patients in group A a band of 60 kDa was detected, which was also detected in 19.2% of patients in group NA. CONCLUSIONS: a negative answer to the question about raw or undercooked fish ingestion has very high sensitivity and NPV (98.39%), and is thus reasonably reliable to rule out anisakidosis. The absence of cutaneous sensitization to crude A. simplex extract gives a high probability (95.56%) that the illness is absent. The presence of a band of about 60 kDa in immunoblotting would be useful for diagnosis.

RESUMO

OBJECTIVE: To examine whether extremely low birth weight (ELBW) infants who undergo Cardiopulmonary Resuscitation (CPR) in the delivery room present poorer survival and greater short-term neurological and general morbidity than those who do not. METHODS: In a retrospective cohort of 150 ELBW infants born at our hospital between 2000 and 2004, those who needed CPR and those who did not were compared for mortality and short-term general and neurological morbidity. Infants with major birth defects, suspicion of genetic disease and those without a proactive perinatal attitude in the delivery room were excluded. CPR was defined as the administration of chest compressions and/or epinephrine in the delivery room. RESULTS: 150 infants were included, with gestational ages of 23-27 weeks (mean 25.6+/-1.2), birth weight of 425-995 grams (mean 745.2+/-132). Delivery room CPR was given to 32 infants (21.4%). No differences in perinatal characteristics were found except for lower pH and Apgar score and a higher SNAPPE score in infants who underwent CPR. Survival at discharge was similar (62.5% vs 76.3% for those without CPR). Infants who received CPR needed more surfactant, oxygen and higher median airway pressure than infants who did not. Air leaks and coagulopathy were more frequent in CPR infants (p<0.01). Prevalence of bronchopulmonary dysplasia, necrotizing enterocolitis and retinopathy was similar in the two groups. No statistical differences between ELBW infants who needed CPR and those who did not were found in prevalence of intraventricular haemorrhage (IVH) (62.5% vs 52.5%), IVH III (31.2% vs 17.7%), periventricular haemorrhagic infarction (PHI) (18.7% vs 11%) or cystic periventricular leucomalacia (PVL) (15.6% vs 11%). However, in a combined analysis of neurological morbidity (IVH III and/or PVL and/or PHI), significant differences between the two groups were found (46.7% vs 21.6%; p=0.01). CONCLUSION: This study does not support poorer survival or significant non-neurological morbidity during the neonatal period in ELBW infants who receive CPR. Although the prevalence of individual neurological problems was similar in the two groups, CPR was associated with a clear increase in general neurological morbidity, with a three-times greater risk of brain damage.

RESUMO

High-intensity focused ultrasound (HIFU) is a minimally invasive therapy modality in which ultrasound beams are concentrated at a focal region, producing a rise of temperature and selective ablation within the focal volume and leaving surrounding tissues intact. HIFU has been proposed for the safe ablation of both malignant and benign tissues and as an agent for drug delivery. Magnetic resonance imaging (MRI) has been proposed as guidance and monitoring method for the therapy. The identification of regions of interest is a crucial procedure in HIFU therapy planning. This procedure is performed in the MR images. The purpose of the present research work is to implement a time-efficient and functional segmentation scheme, based on the watershed segmentation algorithm, for the MR images used for the HIFU therapy planning. The achievement of a segmentation process with functional results is feasible, but preliminary image processing steps are required in order to define the markers for the segmentation algorithm. Moreover, the segmentation scheme is applied in parallel to an MR image data set through the use of a thread pool, achieving a near real-time execution and making a contribution to solve the time-consuming problem of the HIFU therapy planning.

RESUMO

OBJECTIVES: To determine the cerebrospinal fluid (CSF) white blood cell (WBC) count of normal term neonates, and compare the CSF WBC profile of normal and symptomatic infants without infection of the central nervous system (CNS). METHOD: Neonates were included if (a) they were at risk of congenital Toxoplasma infection and had undergone a lumbar puncture to assess CNS involvement, and (b) serial specific serum IgG and IgM determinations had ruled out congenital infection. According to neonatal chart reviews, 30 consecutive patients without CNS infection were classified as normal (absolutely asymptomatic) or symptomatic (any kind of symptoms). RESULTS: CSF WBC count was higher in 11 symptomatic (7/mm(3), 0-30/mm(3)) than in 19 normal (1/mm(3), 0-5/mm(3)) neonates (p<0.01). CONCLUSION: Normal neonatal CSF contains up to 5 WBCs/mm(3). Mild pleocytosis can be found in symptomatic infants without CNS infection.

RESUMO

Premature babies < or = 35 weeks gestation, with or without chronic lung disease (CLD), and infants affected by severe congenital heart disease should be considered high risk population for RSV infection and hospitalization. Hygienic measures and RSV monoclonal antibodies (palivizumab) have been found useful in decreasing rates of RSV hospitalization in these patients. Guidelines for their administration include: a) strongly recommended use in premature babies < or = 28 weeks gestation, or born between 29-32 weeks gestation and less than 6 months at start of RSV station or discharged along it, or affected by CLD in treatment during last 6 months or by severe congenital heart disease. Last two groups could be prophylaxed for two RSV seasons. b) Recommended use among premature babies between 32-35 weeks gestation and less than 6 months of age and presenting two or more risk factors: chronologic age < 10 weeks at start of RSV station, breastfeeding < or = 2 months (physician prescription), sibling < 14 years old, day-care assistance, family history of wheezing, > or = 4 adults at home, airways malformation or neuromuscular disease.

RESUMO

INTRODUCTION: The gluten-free diet has traditionally been accepted as a healthy diet, but there are articles advocating that it may have some nutritional deficiencies. The current study assesses whether there was any change in the contributions of calories, essential elements, proportion of fatty acids, vitamins, minerals and fiber in children who were diagnosed with celiac diseases, comparing the diet with gluten prior one year after diagnosis with the diet without gluten to the year of diagnosis. The level of clinical or analytical impact that nutritional deficits could have was also assessed. MATERIAL AND METHODS: A prospective,descriptive, observational study in which information was collected from a dietary survey, anthropometric and analytical data at pre-diagnosis of celiac disease and following a gluten diet and one year after celiac disease diagnosis, under gluten-free diet. RESULTS: A total of 37 patients meet the study criteria. A decrease in the intake of saturated fatty acids was found, with an increase of monounsaturated fatty acids and an increase in the intake of phosphorus in the diet without gluten. A deficient intake of vitamin D was found in both diets. Clinically, at year of gluten-free diet there was an improvement in weight and size. Analytically, there was an improvement in hemoglobin, ferritin, vitamin D, and parathyroid hormone in plasma. CONCLUSION: The gluten-free diet has minimal deficiencies, similar to those present in the diet with gluten, with an improvement in the lipid profile by increasing the proportion of monounsaturated fatty acids to the detriment of saturated fatty acids.

RESUMO

The present paper describes the calibration of selected passive samplers used in the quantitation of trichlorophenol and trichloroanisole in wineries' ambient air, by calculating the corresponding sampling rates. The method is based on passive sampling with sorbent tubes and involves thermal desorption-gas chromatography-triple quadrupole mass spectrometry analysis. Three commercially available sorbents were tested using sampling cartridges with a radial design instead of axial ones. The best results were found for Tenax TA™. Sampling rates (R-values) for the selected sorbents were determined. Passive sampling was also used for accurately determining the amount of compounds present in the air. Adequate correlation coefficients between the mass of the target analytes and exposure time were obtained. The proposed validated method is a useful tool for the early detection of trichloroanisole and its precursor trichlorophenol in wineries' ambient air while avoiding contamination of wine or winery facilities.
