RESUMO

OBJECTIVES: To describe the Quality of Life (QOL) of breast-cancer patients diagnosed with COVID-19 and analyse its evolution, compare the QOL of these patients according to the COVID-19 wave in which they were diagnosed, and examine the clinical and demographic determinants of QOL. METHODS: A total of 260 patients with breast cancer (90.8% I-III stages) and COVID-19 (85% light/moderate) were included (February-September 2021) in this study. Most patients were receiving anticancer treatment (mainly hormonotherapy). Patients were grouped according to the date of COVID-19 diagnosis: first wave (March-May 2020, 85 patients), second wave (June-December 2020, 107 patients) and third wave (January-September 2021, 68 patients). Quality of Life was assessed 10 months, 7 months, and 2 weeks after these dates, respectively. Patients completed QLQ-C30, QLQ-BR45, and Oslo COVID-19 QLQ-PW80 twice over four months. Patients ≥65 also completed QLQ-ELD14. The QOL of each group and changes in QOL for the whole sample were compared (non-parametric tests). Multivariate logistic regression identified patient characteristics related to (1) low global QOL and (2) changes in Global QOL between assessments. RESULTS: Moderate limitations (>30 points) appeared in the first assessment in Global QOL, sexual scales, three QLQ-ELD14 scales, and 13 symptoms and emotional COVID-19 areas. Differences between the COVID-19 groups appeared in two QLQ-C30 areas and four QLQ-BR45 areas. Quality of Life improvements between assessments appeared in six QLQ-C30, four QLQ-BR45 and 18 COVID-19 questionnaire areas. The best multivariate model to explain global QOL combined emotional functioning, fatigue, endocrine treatment, gastrointestinal symptoms, and targeted therapy (R2  = 0.393). The best model to explain changes in global QOL combined physical and emotional functioning, malaise, and sore eyes (R2  = 0.575). CONCLUSIONS: Patients with breast cancer and COVID-19 adapted well to illness. The few differences between wave-based groups (differences in follow-up notwithstanding) may have arisen because the second and third waves saw fewer COVID restrictions, more positive COVID information, and more vaccinated patients.

RESUMO

Cyclooxygenase-2 (COX-2) and its metabolic product prostaglandin E2 (PGE2 ) are induced in response to growth factors, inflammatory cytokines, tumor promoters, activated oncogenes, and, in the skin, ultraviolet (UV) radiation. Accumulating evidence suggests a role for the COX-2/PGE2 pathway in tumorigenesis in various tissue types including cutaneous squamous cell carcinoma. There is also strong evidence for a role in the development of actinic keratoses (AKs) - common dysplastic lesions of the skin associated with UV radiation overexposure - considered as part of a continuum with skin cancer. Non-steroidal anti-inflammatory drugs (NSAIDs) exert their anti-inflammatory, analgesic, and antipyretic effects by reversibly or irreversibly acetylating COX isoforms, inhibiting downstream prostaglandins, and may have a chemopreventive role in malignancies, including skin cancer. Topical treatment of AK lesions with the NSAID diclofenac sodium 3% in combination with hyaluronic acid 2.5% has been shown to be effective and well tolerated, although the mechanism of action remains to be elucidated.

RESUMO

Molecular methods are increasingly used for both species identification of sandflies and assessment of their population structure. In general, they are based on DNA sequence analysis of targets previously amplified by PCR. However, this approach requires access to DNA sequence facilities, and in some circumstances, it is time-consuming. Though DNA sequencing provides the most reliable information, other downstream PCR applications are explored to assist in species identification. Thus, it has been recently proposed that the amplification of a DNA region encompassing partially both the cytochrome-B (cytb) and the NADH dehydrogenase 1 (nd1) genes followed by RFLP analysis with the restriction enzyme Ase I allows the rapid identification of the most prevalent species of phlebotomine sandflies in the Mediterranean region. In order to confirm the suitability of this method, we collected, processed, and molecularly analyzed a total of 155 sandflies belonging to four species including Phlebotomus ariasi, P. papatasi, P. perniciosus, and Sergentomyia minuta from different regions in Spain. This data set was completed with DNA sequences available at the GenBank for species prevalent in the Mediterranean basin and the Middle East. Additionally, DNA sequences from 13 different phlebotomine species (P. ariasi, P. balcanicus, P. caucasicus, P. chabaudi, P. chadlii, P. longicuspis, P. neglectus, P. papatasi, P. perfiliewi, P. perniciosus, P. riouxi, P. sergenti, and S. minuta), from 19 countries, were added to the data set. Overall, our molecular data revealed that this PCR-RFLP method does not provide a unique and specific profile for each phlebotomine species tested. Intraspecific variability and similar RFLP patterns were frequently observed among the species tested. Our data suggest that this method may not be applicable throughout the Mediterranean region as previously proposed. Other molecular approaches like DNA barcoding or phylogenetic analyses would allow a more precise molecular species identification.

RESUMO

PURPOSE: More research is needed into Quality of Life (QoL) in young early-stage breast cancer patients in the long-term. Knowledge of long-term effects of surgery on QoL in breast cancer patients is limited. The purpose of this study was to assess QoL in premenopausal Spanish early- stage breast cancer patients over a long follow-up period and evaluate differences among surgery-treated groups and the influence of time on patient QoL. METHODS: 243 premenopausal stage I-III relapse-free breast cancer patients completed the EORTC QLQ-C30 and QLQ-BR23 questionnaire once during follow-up (5-20 years after surgery). Univariate and multivariate logistic regression analyses were performed to estimate the results. RESULTS: QoL mean scores were high in most areas (>80 points in functioning: <20 points in symptoms areas). Limitations were moderate (>30 points) in global QoL, sleep disturbance, future perspective, sexual areas, and hot flashes. Mastectomized patients had a 4-fold greater risk of low scores in body image. Patients with a longer follow-up showed lower systemic side effects, hot flashes and breast symptoms. CONCLUSIONS: QoL in Spanish premenopausal early-stage breast cancer patients in a long follow-up after surgery is high. Differences in QoL among surgery-treated groups are limited. Time since surgery influences treatment side effects.

RESUMO

AIM OF THE STUDY: Quality of life (QL) is important in premenopausal long-term breast cancer survivors. In this study we assessed QL and factors associated with future perspective and global QL in premenopausal early-stage long-term breast cancer survivors from Spain. MATERIAL AND METHODS: 243 premenopausal stage I-IIIA relapse-free breast cancer patients who had received surgery 5-20 years previously completed EORTC QLQ-C30 and QLQ-BR23 questionnaires once during follow-up. Univariate and multivariate logistic regression analyses were performed. RESULTS: QL mean scores were high in most areas (> 80 in functioning; < 20 in symptoms). The main factors for future perspective were emotional and social functioning, fatigue, breast symptom, and body image. The main factors for global QL were fatigue, pain and physical functioning, and emotional and social functioning. The best logistic model to explain future perspective associated high emotional and social functioning and low breast symptoms with a lower risk of low future perspective (R(2) = 0.56). Higher scores in physical and emotional functioning and lower scores in fatigue were associated with a lower risk of low global QL (R(2) = 0.50). CONCLUSIONS: Psychological, social, and physical factors were found to be possible determinants of global QL and future perspective. QL in premenopausal early-stage long-term breast cancer survivors may benefit from multidisciplinary treatment.

RESUMO

BACKGROUND: Intralesional injection of Candida antigen appears to be an effective alternative for the treatment of warts. AIM: To determine the efficacy and safety of this treatment. METHODS: We retrospectively reviewed records of all children who received intralesional injection of Candida antigen at our center from January 2008 to July 2013. RESULTS: From a total of 220 patients, 156 (70.9%) had a complete response, 37 (16.8%) had a partial response, and 27 (12.2%) had no improvement. An average of 2.73 treatments was needed. Forty-seven of the patients with more than one wart (21.3%) also noted at least partial resolution of untreated warts at distant sites. Twenty-seven of the 47 patients (57.4%) had complete resolution. All treated patients experienced some discomfort at the time of the injection, but no serious side effects were reported. DISCUSSION: We report our results using this approach in a large group of children. CONCLUSION: Intralesional injection of Candida antigen is an effective and safe therapy for children with multiple and recalcitrant cutaneous warts.

RESUMO

This article reviews the contemporary and inclusive definition of cancer survivorship, including patients with and without disease who have completed or continue to undergo treatment. The Spanish Society of Medical Oncology (SEOM) describes in this article the needs of these patients and outlines a care model based on an estimation of cancer incidence and identification of patient needs, to enable the provision of practical actions to achieve effective care. The objectives of this review are to identify the main effects of cancer on survivors and to establish appropriate ways of measuring these effects, as well as discussing the management of physical, psychological and social, occupational, financial, and other health-related needs. We suggest a multidisciplinary care model and training programs for the different professionals involved in care, and highlight challenges and the future role of the SEOM and health-care policy in ensuring optimum care of cancer survivors.

RESUMO

This revised consensus statement of the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Pathological Anatomy (SEAP) updates the recommendations for biomarkers use in the diagnosis and treatment of breast cancer that we first published in 2018. The expert group recommends determining in early breast cancer the estrogen receptor (ER), progesterone receptor (PR), Ki-67, and Human Epidermal growth factor Receptor 2 (HER2), as well as BReast CAncer (BRCA) genes in high-risk HER2-negative breast cancer, to assist prognosis and help in indicating the therapeutic options, including hormone therapy, chemotherapy, anti-HER2 therapy, and other targeted therapies. One of the four available genetic prognostic platforms (Oncotype DX®, MammaPrint®, Prosigna®, or EndoPredict®) may be used in ER-positive patients with early breast cancer to establish a prognostic category and help decide with the patient whether adjuvant treatment may be limited to hormonal therapy. In second-line advanced breast cancer, in addition, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) and estrogen receptor 1 (ESR1) should be tested in hormone-sensitive cases, BRCA gene mutations in HER2-negative cancers, and in triple-negative breast cancer (TNBC), programmed cell death-1 ligand (PD-L1). Newer biomarkers and technologies, including tumor-infiltrating lymphocytes (TILs), homologous recombination deficiency (HRD) testing, serine/threonine kinase (AKT) pathway activation, and next-generation sequencing (NGS), are at this point investigational.

RESUMO

OBJECTIVE: This study evaluates satisfaction with care (SC) in cancer patients treated at a Spanish day hospital to identify SC determinants and assess the relationship between SC and quality of life. METHODS: One hundred seventy-six patients with different tumour sites and disease stages completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Cancer Outpatient Satisfaction with Care questionnaire for chemotherapy (OUT-PATSAT35 CT), the Oberst patients' perception of care quality and satisfaction scales, and an item on intention to recommend the hospital. Frequencies in the SC instruments, Spearman correlations between each scale of the OUT-PATSAT35 CT and overall satisfaction and between the subscales of OUT-PATSAT35 CT and of QLQ-C30 were calculated, and the determinants of patients' SC were calculated through multivariate regression models. RESULTS: Satisfaction with care was high: mean scores were >70 in all OUT-PATSAT35 CT areas except doctor availability and environment. These scores were in line with the other SC instruments. Correlation with overall satisfaction was high and statistically significant (p < 0.01) for all subscales, especially for the nurses domain, which also had higher SC scores. Correlations between the EORTC QLQ-C30 and the OUT-PATSAT35 CT were low (≤ 0.35). Younger patients and those with breast cancer showed significantly lower satisfaction in most subscales. Unmarried patients and patients that had undergone surgery reported lower satisfaction only in specific subscales. CONCLUSIONS: Satisfaction with care among cancer patients treated at the day hospital is high. Nurses play a key and successful role. Age and tumour location revealed stronger relationships with SC. Correlations between SC and quality of life indicate that these concepts are complementary.

RESUMO

OBJECTIVE: In this article, the quality of life (QOL) of Spanish postmenopausal early-stage breast cancer patients who have finished endocrine therapy (ET), QOL changes after endocrine therapy cessation, and the differences between two endocrine therapy modalities (tamoxifen or aromatase inhibitor [AI]) are studied. More QOL information after endocrine therapy cessation is needed. METHODS: A prospective cohort study was performed. Participating in the study were 158 postmenopausal patients who had received tamoxifen or AI for 5 years. In some cases, endocrine therapy may have changed during those 5 years.Patients completed the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR45 questionnaires at baseline, after 6 months, and after 1 year of follow-up. Patients older than 65 years also completed the QLQ-ELD14. Linear mixed-effect models were used to evaluate longitudinal changes in QOL and differences in QOL between endocrine therapy modalities. RESULTS: QOL scores for the whole sample throughout follow-up were high (>80/100 points) in most QOL areas. Moderate limitations (>30 points) occurred in the QLQ-BR45 in sexual functioning and sexual enjoyment, future perspective, and joint symptoms. Moderate limitations also occurred in the QLQ-ELD14 in worries about others, maintaining purpose, joint stiffness, future worries, and family support. In those who had finished endocrine therapy, pain was reduced in all three assessments conducted during the 1-year follow-up period in both groups. Tamoxifen patients showed better QOL in functioning (role functioning, global QOL, financial impact), symptoms (pain), and emotional areas (future perspective and worries about others) than AI patients but worse QOL in skin mucosis symptoms. CONCLUSIONS: The results of this study show that postmenopausal early-stage breast cancer patients adapted well to their disease and endocrine therapy treatment. QOL improvements in the 1-year follow-up period appeared in one key area: pain. Differences between endocrine therapy modalities suggested QOL was better in the tamoxifen group than in the AI group.

RESUMO

BACKGROUND: The addition of dendritic cell vaccines (DCV) to NAC could induce immune responses in those patients with residual disease (RD) by transforming the tumor microenvironment. METHODS: Core diagnostic biopsies and surgical specimens from 80 patients (38 in the vaccinated group plus NAC (VG) and 42 in the control group (CG, treated only with NAC) were selected. We quantify TILs (CD8, CD4 and CD45RO) using immunohistochemistry and the automated cellular imaging system (ACIS III) in paired samples. RESULTS: A CD8 rise in TNBC samples was observed after NAC plus DCV, changing from 4.48% in the biopsy to 6.70% in the surgical specimen, not reaching statistically significant differences (p = 0.11). This enrichment was seen in up to 67% of TNBC patients in the experimental arm as compared with the CG (20%). An association between CD8 TILs before NAC (4% cut-off point) and pathological complete response in the VG was found in the univariate and multivariate analysis (OR = 1.41, IC95% 1.05-1.90; p = 0.02, and OR = 2.0, IC95% 1.05-3.9; p = 0.03, respectively). CONCLUSION: Our findings suggest that patients with TNBC could benefit from the stimulation of the antitumor immune system by using DCV together with NAC.

RESUMO

Background: Metastatic breast cancer (mBC) causes nearly all BC-related deaths. Next-generation sequencing (NGS) technologies allow for the application of personalized medicine using targeted therapies that could improve patients' outcomes. However, NGS is not routinely used in the clinical practice and its cost induces access-inequity among patients. We hypothesized that promoting active patient participation in the management of their disease offering access to NGS testing and to the subsequent medical interpretation and recommendations provided by a multidisciplinary molecular advisory board (MAB) could contribute to progressively overcome this challenge. We designed HOPE (SOLTI-1903) breast cancer trial, a study where patients voluntarily lead their inclusion through a digital tool (DT). The main objectives of HOPE study are to empower mBC patients, gather real-world data on the use of molecular information in the management of mBC and to generate evidence to assess the clinical utility for healthcare systems. Trial design: After self-registration through the DT, the study team validates eligibility criteria and assists patients with mBC in the subsequent steps. Patients get access to the information sheet and sign the informed consent form through an advanced digital signature. Afterwards, they provide the most recent (preferably) metastatic archival tumor sample for DNA-sequencing and a blood sample obtained at the time of disease progression for ctDNA analysis. Paired results are reviewed by the MAB, considering patient's medical history. The MAB provides a further interpretation of molecular results and potential treatment recommendations, including ongoing clinical trials and further (germline) genetic testing. Participants self-document their treatment and disease evolution for the next 2 years. Patients are encouraged to involve their physicians in the study. HOPE also includes a patient empowerment program with educational workshops and videos about mBC and precision medicine in oncology. The primary endpoint of the study was to describe the feasibility of a patient-centric precision oncology program in mBC patients when a comprehensive genomic profile is available to decide on a subsequent line of treatment.

RESUMO

PURPOSE: The OUT-PATSAT35 CT questionnaire evaluates satisfaction with care expressed by cancer outpatients receiving chemotherapy. This study assesses the psychometric properties of the OUT-PATSAT35 CT when applied to a sample of Spanish patients. METHODS: One hundred seventy-six patients with different tumour sites and disease stages completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30, the OUT-PATSAT35 CT, the Oberst patients' perception of care quality and satisfaction scales (OS) and the item on intention to recommend the hospital (IR). Psychometric evaluation of the structure, reliability and validity of the questionnaire was conducted. RESULTS: Multitrait scaling analysis showed that 32 of 34 item-scale correlation coefficients met the standards for convergent validity and that many of them met the standards for discriminant validity. Cronbach's coefficients were good (0.78-0.97) for all scales except doctor availability and environment. Correlations between the QLQ-C30 and the OUT-PATSAT35 CT were low (≤0.40). Correlations between IR and the OUT-PATSAT35 CT were moderate, and correlations between this questionnaire and the OS were fairly low. Areas whose contents were more related had higher correlation coefficients (>0.50) and vice versa (<0.1). Male patients, elderly patients, those with higher education levels, those with higher scores in four OS and patients who had not received surgery showed higher satisfaction with care in several OUT-PATSAT35 CT areas. CONCLUSIONS: The OUT-PATSAT35 CT is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the validation study conducted by the authors of the questionnaire and with the validation study for Spain of the OUT-PATSAT35 RT.

RESUMO

A large area of the terrestrial land surface is used for livestock grazing. Trees on grazing lands provide and can enhance multiple ecosystem services such as provisioning, cultural and regulating, that include carbon sequestration. In this study, we assessed the above- and belowground carbon stocks across six different land-uses in livestock-dominated landscapes of Mexico. We measured tree biomass and soil organic carbon (SOC) stocks in fodder banks, live fences, pasturelands with dispersed trees, secondary forests, and primary forests from three different geographical regions and compared them with conventional open pasturelands respectively. We also calculated tree diversity indices for each land-use and their similarity with native primary forests. The aboveground woody biomass stocks differed significantly between land-uses and followed the gradient from less diverse conventional open pasturelands to silvopastoral systems and ecologically complex primary forests. The SOC stocks showed a differential response to the land-use gradient dependent on the study region. Multivariate analyses showed that woody biomass, fine root biomass, and SOC concentrations were positively related, while land-use history and soil bulk density showed an inverse relationship to these variables. Silvopastoral systems and forest remnants stored 27-163% more carbon compared to open pasturelands. Our results demonstrate the importance of promoting appropriate silvopastoral systems and conserving forest remnants within livestock-dominated landscapes as a land-based carbon mitigation strategy. Furthermore, our findings also have important implications to help better manage livestock-dominated landscapes and minimize pressures on natural protected areas and biodiversity in the hotspots of deforestation for grassland expansion.

RESUMO

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer (BC) subtype and lacks targeted treatment. It is diagnosed by the absence of immunohistochemical expression of several biomarkers, but this method still displays some interlaboratory variability. DNA methylome aberrations are common in BC, thereby methylation profiling could provide the identification of accurate TNBC diagnosis biomarkers. Here, we generated a signature of differentially methylated probes with class prediction ability between 5 non-neoplastic breast and 7 TNBC tissues (error rate = 0.083). The robustness of this signature was corroborated in larger cohorts of additional 58 non-neoplastic breast, 93 TNBC, and 150 BC samples from the Gene Expression Omnibus repository, where it yielded an error rate of 0.006. Furthermore, we validated by pyrosequencing the hypomethylation of three out of 34 selected probes (FLJ43663, PBX Homeobox 1 (PBX1), and RAS P21 protein activator 3 (RASA3) in 51 TNBC, even at early stages of the disease. Finally, we found significantly lower methylation levels of FLJ43663 in cell free-DNA from the plasma of six TNBC patients than in 15 healthy donors. In conclusion, we report a novel DNA methylation signature with potential predictive value for TNBC diagnosis.

RESUMO

INTRODUCTION: Tularemia is a zoonotic disease that has been regularly reported in Spain since 1997. This study analyzes suspected, probable, and confirmed cases of tularemia in the province of Soria, and compares them with tularemia cases recorded in the autonomous community of Castilla y Léon, which, with the exception of 1 sporadic case, occurred in 2 epidemic outbreaks in 1997/1998 and 2007/2008. METHODS: We studied all patients (53) with signs and symptoms of tularemia in the period of 1997 to 2008. Sixty-three serum samples from these patients were tested by a microagglutination assay for antibodies against Francisella tularensis; additionally 10 blood cultures and 1 culture of abscess exudate from an enlarged lymph node were carried out. RESULTS: Over the last decade, 19 cases of tularemia have been diagnosed in Soria (1 sporadic case in 1996, 5 associated with an outbreak reported in 1997/98 and 13 associated with an outbreak occurring in 2007/08). In 95% of the cases, previous contact with hares was reported. The ulceroglandular type was most frequently (62%) observed. F. tularensis was isolated on blood culture in 2 cases. The remaining patients were diagnosed by serology (4 confirmed cases, 13 probable cases). CONCLUSION: The cases of tularemia documented in Soria showed clinical and epidemiological features (predominant ulceroglandular clinical presentation and previous contact with hares) identical to the 1997/98 tularemia outbreak in Castilla y Léon, but contrasted with the 2007/08 outbreak in Castilla y León where typhoidal clinical forms of the disease and a relationship with an increased rodent population (Mycrotus spp) were predominant.

RESUMO

INTRODUCTION: The annual incidence of tuberculosis (TB) from Mycobacterium bovis in humans has considerably declined in industrialised countries since the early twentieth century. The objective of this study was to determine the epidemiological, clinical and microbiological characteristics of patients with this illness in Castile and León (CyL). METHODS: Retrospective study of all M. bovis TB cases in CyL over a 10-year period, comparing the risk factors, the epidemiology and the clinical course between pulmonary (PTB) and extrapulmonary TB (EPTB). RESULTS: 75 cases of TB were due to M. bovis: 45 PTB and 31 EPTB. The annual incidence of TB due to M. bovis was 0.3 cases per 100,000. It remained stable between the first and second five-year period (0.27 vs. 0.33, p=0.656). However, the overall incidence of TB fell in both five-year periods (13.58 vs. 10.71, p<0.0001). The mean age was 66.2+21.3 years, mainly men (63%) and Spanish patients (92%). PTB was significantly more frequent in men, aged over 66 years, with immunosuppressive conditions or who were smokers. Mortality was 9%, associated with higher age, immunosuppression or treatment different from that recommended by the WHO. CONCLUSIONS: The incidence of M. bovis TB in CyL was higher than that for Spain and for other European countries, and remained stable despite the decreased the TB due to MTC. It affected mostly Spanish-born patients who lived in rural areas and with a high mean age.

RESUMO

PURPOSE: This paper studies the Quality of Life (QL) of elderly early-stage breast cancer survivors. The aims are to compare the QL scores of these patients after follow-up with their scores before the start of radiotherapy (RT) and compare QL among different axillary treatment groups. METHODS: Of 173 patients over 65 who began treatment and completed the EORTC QLQ-C30 and QLQ-BR23 and the Interview for Deterioration in Daily Living Activities in Dementia (IDDD) before RT, 138 also completed these questionnaires three years after RT. Longitudinal changes in QL were assessed for the whole sample using linear mixed-effect models. Also assessed were differences in QL scores between axillary treatment groups (axillary node dissection ALND, sentinel lymph node biopsy SLNB, and no surgery) at the end of the follow-up (Anova or Kruskal-Wallis) and differences in the evolution of QL from baseline among these groups (linear regression models). RESULTS: QL scores in the follow-up were high (>70/100 points) in most QL areas, with moderate limitations (>30) in sexual functioning and enjoyment. Five areas (pain, nausea/vomiting, financial impact, breast symptoms and IDDD) improved significantly (<6 points) in the follow-up. The ALND group scored less for the future perspective item (15-20 points) in the follow-up than the other two axillary treatment groups. No differences between the pre-treatment and follow up assessments regarding treatment were found among the axillary treatment groups. CONCLUSIONS: Our results suggest that early-stage breast cancer patients adapted well both to their disease and treatments over the follow-up period and to the administration of RT. There were few QL differences between the axillary treatment groups.

RESUMO

INTRODUCTION AND OBJECTIVES: A retrospective study was conducted by collecting microbiological tuberculosis (TB) data in Castile and León during the year 2013 in order to determine the incidence and distribution of TB, and resistance to the tuberculostatic drug, and compare them with the epidemiological data provided by the Department of Epidemiological Surveillance (SIVE). MATERIAL AND METHODS: Microbiologists of the 14 hospitals of the Castile and León public health network (GRUMICALE) collected epidemiological, microbiological, and management data from the Microbiology laboratories in the community during the year 2013. A single isolate of Mycobacterium tuberculosis complex (MTC) per patient was considered. RESULTS: The study included a total of 270 MTC isolates (an incidence rate of 11.63 cases/100,000 inhab./year). A total of 288 cases of TB (11.43 cases/100,000 inhab. year) were recovered using epidemiological data, which included 243 confirmed, 29 suspected, and 16 as probable cases. Pulmonary TB was predominant, followed a long way off by the pleural TB and the remaining locations. A total of 27,620 samples were processed for mycobacterial detection. Mycobacterial growth was observed in 3.46% of automated fluid cultures, and 50.37% were positive by direct staining of the smear. Resistance to one tuberculostatic drug, mostly to isoniazid, was observed in 16 (5.92%) isolates of Mycobacterium tuberculosis (MT). The province with greater incidence and number of isolates was León (24.23 cases/100,000 inhab./year), with the highest being observed in El Bierzo health area (30.46 cases/100,000 inhab./year). CONCLUSIONS: An adequate collection of microbiological information is essential to determine the epidemiology of TB in our region.
