RESUMO

Background and Objectives: Endobiogeny is a global systems approach to human biology based on the concept that the endocrine system manages the metabolism. Biology of function (BoF) indices are diagnostic tools in endobiogenic medicine that reflect the action of the endocrine system on the cells and the metabolic activity of an organism. Kidney transplant recipients are a very specific patient population due to their constant use of immunosuppressive agents such as steroids and anamnesis of chronic kidney disease. The aim of this study was to assess the tendencies of endobiogenic BoF indices in a kidney transplant recipient population and to determine the relationship between BoF index values and histology-proven kidney transplant rejection. Materials and Methods: A total of 117 kidney transplant recipients undergoing surveillance or indication allograft biopsy were included in this study. Endobiogenic BoF indices were calculated from complete blood count tests taken before the kidney biopsy. Histology samples were evaluated by an experienced pathologist according to the Banff classification system. Clinical and follow-up data were collected from an electronic patient medical record system. Results: Overall, <35% of the patients had BoF index values assumed to be normal, according to the general population data. Additionally, >50% of the patients had lower-than-normal adaptation, leucocyte mobilization, genital, and adjusted genital ratio indices, while the Cata-Ana, genito-thyroid ratio, adrenal gland, and cortisol indices were increased in >50% of the transplant recipients. The adaptation index was significantly higher in patients with biopsy-proven transplant rejection and demonstrated an AUC value of 0.649 (95%CI 0.540-0.759) for discriminating rejectors from patients without transplant rejection. Conclusions: Most of the kidney transplant recipients had abnormal BoF index values, reflecting increased corticotropic effects on their cells. The adaptation index distinguished patients with biopsy-proven transplant rejection from those without it.

RESUMO

Background and Objectives: Vaccination is one means of SARS-CoV-2 prevention and control. However, despite the effectiveness of vaccination, adverse reactions continue to require vigilance and monitoring. The researchers emphasize the possibility that some of the reported side effects may be psychological in origin. Based on this hypothesis, the main goal of this study was to evaluate the emotional dispositions of healthcare workers who experienced emotions before vaccination and adverse reactions after vaccination. Materials and Methods: This study was conducted between February and May 2021 in the Kaunas Clinics of the University of Health Sciences. A total of 2117 employees of the clinic departments who were vaccinated with two doses of the Pfizer-BioNTech vaccine participated in this study. Statistical analysis was performed on the data using IBM SPSS Statistics®. Results: Most participants (74.5%) experienced systemic (including local) adverse events; 16.5% experienced only local adverse events, and 9.1% experienced no adverse events. The frequency of systemic (including local) adverse events reduced with increasing age (p < 0.05). The main emotions that participants experienced before vaccination were anxiety (37.88%) and happiness (39.02%). Systemic (including local) adverse events occurred 1.26 times more frequently in women than men (77.44% vs. 61.6%, p < 0.05), while local adverse events occurred 1.4 times more often in male participants than in female participants (21.39% vs. 15.27%, p < 0.05). Among the respondents who did not experience adverse events, the most common emotion felt was happiness (25.5%), and most of the participants who experienced systemic (including local) adverse events felt anxiety (42.6%). Conclusions: The information about vaccination and potential adverse events should be targeted at younger persons. It is recommended that women, more than men, should receive professional counseling from psychologists or psychotherapists. The public dissemination of positive messages about the benefits and safety of vaccines prior to a vaccination campaign may alleviate the tension or anxiety felt regarding potential adverse events. Healthcare specialists-both those who work directly with vaccines and those who do not-should maintain a positive psychological attitude towards vaccination, as this can increase patient satisfaction with the benefits of vaccines.

RESUMO

Background and Objectives: Although multimorbidity poses many challenges for both individuals and healthcare systems, information on how these patients assess the quality of their healthcare is lacking. This study assessed the multimorbid patients' satisfaction with their healthcare. Materials and Methods: This cross-sectional study was a part of a project Joint Action-Chronic Diseases and Promoting Healthy Ageing across the Life Cycle and its implementation. The study included 400 patients with arterial hypertension and at least one concomitant chronic disease. Patients completed The Patient Assessment of Care for Chronic Conditions Plus (PACIC+) questionnaire, EuroQol Five-Dimensions-Three-Level Quality of Life questionnaire, and Hospital Anxiety and Depression scale. Results: The mean age of the participants was 65.38 years; there were 52.5% women. The mean PACIC+ 5As summary score was 3.60. With increasing age, participants rated worse on most PACIC+ subscales. Participants who assessed their quality of life as worse were also less satisfied with their healthcare. The presence of three or more concomitant diseases negatively affected PACIC+ scores. Patients with ischemic heart disease and heart failure had lower PACIC+ scores on most subscales, whereas patients with atrial fibrillation had lower scores only on the Agree subscale. The presence of diabetes was not associated with worse PACIC+ scores; moreover, the scores in Assist and Arrange subscales were even better in diabetic patients (3.36 vs. 2.80, p = 0.000 and 3.69 vs. 3.13, p = 0.008, respectively). Patients with chronic obstructive pulmonary disease, asthma, and musculoskeletal disorders showed lower PACIC+ scores. Conclusions: Older age, worse self-assessed health state, presence of three or more diseases, and certain chronic diseases were associated with lower patients' satisfaction with their healthcare. Personalized healthcare, increasing competencies of primary healthcare teams, healthcare services accessibility, and financial motivation of healthcare providers may increase multimorbid patients' satisfaction with their healthcare.

RESUMO

Background and Objectives: The safety and effectiveness of vaccines are among the key priorities in COVID-19 pandemic management. Moreover, evidence-based data regarding vaccine safety and immunogenicity can play an important role in building the trust of the community regarding vaccination. The aim of this study was to investigate the safety and immunogenicity of Pfizer-BioNTech vaccine among healthcare workers in one hospital, 21 days after first dose. Materials and Methods: This study was conducted in the Hospital of the Lithuanian University of Health Sciences between February and March 2021. Hospital employees who arrived to receive the second dose of the Pfizer-BioNTech vaccine 21 days after the first one were invited to participate in the study: they were asked to complete an anonymous adverse events questionnaire and were offered a SARS-CoV-2 IgG/IgM rapid test. The study was performed at a single point, 21 days after the first dose of the vaccine. Results: Data of 4181 vaccine recipients were analysed. The first vaccine dose was associated with a 53.6% incidence of adverse events, mainly local reactions. Adverse events occurred more frequently in younger participants and women. Moderate adverse events were experienced by 1.4% of the vaccine recipients; 6.2% were incapacitated. Of the 3439 participants who performed a rapid IgG test, 94.5% were positive for IgG antibodies after the first vaccine dose. Seroconversion rates were lower in participants older than 47 years. Conclusions: Despite 1.4% moderate adverse events, no safety concerns or anaphylaxis were identified. The Pfizer-BioNTech vaccine induced an immune response in the overwhelming majority of recipients after a single dose. Younger participants experienced adverse events and were positive for IgG antibodies more frequently than older counterparts. It is important to mention that this study specifically considered short-term safety and reactions following vaccination and that long-term adverse effects were not investigated in the study. Thus, future research into both long-term adverse reactions and immune system programming is essential.

RESUMO

OBJECTIVE: The aim was to identify the critical levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor-A in umbilical cord blood that could be used as markers for predicting the central nervous system (CNS) damage and retinopathy of prematurity (ROP) in preterm infants. STUDY DESIGN: A total of 158 preterm infants, born at 22 to 34 weeks of gestation, were evaluated in the first week after birth and at 36 to 37 weeks of postconceptual age. RESULTS: A significant relationship between CNS changes and concentrations of IL-6 (p < 0.001) and TNF-α (p < 0.001) in umbilical cord blood at 22 to 34 weeks of gestation was determined. The concentration of IL-6 >13.0 pg/mL predicts significant CNS damages in 36 to 37-week infants (p = 0.013). ROP was diagnosed in 24.8% infants (n = 149). It was detected that the levels of TNF-α >116.4 pg/mL (p < 0.001) and IL-6 >13.0 pg/mL (p < 0.05) in umbilical cord blood could predict 2 to 3/3 to 4 stages of ROP. CONCLUSION: Critical values of IL-6 and TNF-α in predicting ≥grade III intraventricular hemorrhage in the early adaptation and in predicting marked CNS damages and severe ROP stages in the later adaptation of preterm infants were determined.

RESUMO

Background and objectives: Reproductive disorders may occur not only due to environmental factors (air pollution, stressful lifestyle, previous abortions or the use of contraceptives) but also due to genetic factors. Materials and Methods: The aim of the study was to identify the range and frequency of chromosomal aberrations in couples (n = 99) with infertility or recurrent miscarriages in Lithuania. The data were collected from the out-patient medical histories. The couples were divided into three groups based on pregnancy, childbirth and the number of miscarriages. The Chi-square test was used to carry out the statistical analysis, and the statistical significance was (p < 0.05). Results: There were 6.6% (n = 13) structural changes observed in the karyotype tests. Chromosomal aberrations were found in 3% (n = 6) of the subjects, while 3.6% (n = 7) of them had chromosomal length polymorphisms. No difference was found between the aberration frequency in the karyotypes of men and women (p > 0.05). The most common aberrations were balanced translocations (23.1%, n = 3) which accounted for 15.4% of the reciprocal (n = 2) and 7.7% of the Robertsonian type (n = 1) of translocations. The most frequent aberrations were found in couples with the inability to conceive (42.9% (n = 3), p = 0.031). The childless couples and those with recurrent miscarriages showed an aberration rate of 8.2% (n = 5), while in the couples with at least one child it was 16.1% (n = 5). The group of couples unable to conceive had a significantly higher aberration rate of 28.6% (n = 2), p = 0.029. Miscarriages in partners' families accounted for 8.1%. Miscarriages on the female side of the family accounted for 4.5% (n = 9), on the male side it accounted for 2.5% (n = 5) and on both sides it accounted for 1.1% (n = 2). There were no statistically significant differences observed between the female and male sides (p > 0.05). The miscarriages observed in the second group of couples (childless with ≥2 miscarriages) were more frequent at 18.1% (n = 11), in the third group (having children ≥2 miscarriages) they were less frequent at 12.9% (n = 4), while no miscarriages were recorded in the first group of infertile couples. In total, 3% of the identified significant chromosomal aberrations were likely to trigger miscarriages or the inability to conceive. Conclusions: In couples with reproductive disorders, chromosomal mutations and chromosomal length polymorphisms were found at similar rates: 3% vs. 3.6%. The highest aberration rate was found in couples that were unable to conceive, a lower one was found in a group with children and ≥2 miscarriages, and the lowest one was found in a childless group of subjects with ≥2 miscarriages. The miscarriage rate in partner families was 8.1%; however, no difference was found between the male and female sides.

RESUMO

Hair loss can significantly impact an individual's psychological state, self-image, and can lead to numerous personal, social, and occupational problems. Although these impairments are well documented in primary studies and reviews, and the need for appropriate psychological help is emphasized, there is still a lack of knowledge for a broader and specific picture. The patient's perspective is vital while seeking to understand the content of the variables like "impaired body image" or "low self-esteem." This article advocates the need for studies involving methodologies allowing to explore the complexity and depth of experience. A better understanding of patients' states, reactions, and needs might contribute to the practice of healthcare professionals seeking the best possible help. This study aimed to explore the lived experience of people with alopecia areata in Lithuania using a phenomenological approach. Experiences of six patients with varying degrees of alopecia areata, four women and two men (mean age 27 years), were explored. Data were obtained using an unstructured interview and were analyzed based on Colaizzi's phenomenological approach. This article explores findings related to patient's psychological state covering two superordinate themes: (a) devastating loss of perceived self and (b) grieving and the process of acceptance. The insights for the appropriate therapeutic intervention were formulated.

RESUMO

Background and objectives: Noninvasive prenatal testing (NIPT), which has been introduced clinically since 2011, uses the circulating cell-free fetal DNA in the maternal blood to evaluate the risk of a chromosomal anomaly. The aim of this study was to examine the effectiveness of NIPT using a single nucleotide polymorphism method. Materials and Methods: A retrospective study was conducted between 2013 and 2019. The Natera Panorama test was used to analyze the risk of trisomies 21, 18, 13, X monosomy, trisomy, and other sex chromosome abnormalities. A positive result of NIPT for aneuploidy was confirmed by invasive testing. Results: 850 women with a singleton pregnancy participated in the study. The median fetal fraction was 9.0%. The fetal fraction was lower in the no-call group (3.1%) compared with the group that received a call (9.1%) (p < 0.001). A positive correlation was determined between the gestational age and the fetal fraction (r = 0.180, p < 0.001). The overall positive predictive value (PPV) of NIPT for trisomy 21 (n = 9), trisomy 18 (n = 3) and XYY syndrome (n = 1) was 100%. Conclusions: The results of present study showed 100% PPV effectiveness of NIPT Panorama test detecting trisomies of 21 and 18 chromosomes, as well as XYY syndrome in the studied cohort. Therefore, NIPT due to its high PPV, significantly reduces the need for invasive testing, thereby reducing the risk of miscarriage and stillbirth.

RESUMO

Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a special form of adult food allergy when allergic symptoms are elicited when triggering factor such as exercise is added after ingestion of wheat. Besides the molecular characteristics of wheat proteins, the gastric function is decisive for the allergenic potential. Alterations in the gastric milieu are frequently experienced during a lifetime either physiologically or as a result of gastrointestinal pathologies. Helicobacter pylori infection can lead to hypoacidity and enhance the sensitization risk for food allergens in adults. Gastric transit of food proteins and alterations in the gastric secretion can be disturbed after bariatric surgery such as the laparoscopic adjustable gastric binding (LAGB) procedure used commonly as therapy for morbid obesity. We report a case of WDEIA in a 42-year-old man with H. pylori positive gastritis, 2 years after bariatric surgery and no history of allergy previously. Our presented case strongly suggests that H. pylori-associated gastritis and gastric anatomy and functional changes after adjustable gastric banding lead to the alterations in gastric milieu and may contribute to a development of food allergy in previously non-sensitized patients.

RESUMO

Stargardt disease is a juvenile macular degeneration most often inherited in an autosomal recessive pattern, characterized by decreased vision in the first 2 decades of life. This report presents a clinical case of Stargardt disease: a 10-year-old female patient complained of blurry vision, and in a 4-year period, her visual acuity was reduced from OD=0.3 and OS=0.3 to OD=0.08 and OS=0.1, respectively. A genetic analysis revealed a rare combination of 2 homozygous recessive mutations in the ABCA4 gene, which caused Stargardt disease. The presence of different genetic mechanisms leading to a severe disease phenotype can challenge molecular geneticists, ophthalmologists, and genetic counselors.

RESUMO

Multiple endocrine neoplasia type 1 (MEN 1) is a rare syndrome inherited in an autosomal dominant pattern, characterized by combinations of tumors of the parathyroid glands, pituitary gland, and pancreatic islet cells and more rare tumors of endocrine organs and nonendocrine tissues. Germline mutations in the MEN1 gene are responsible for the MEN 1 syndrome, leading to an inactive form of menin protein. Benign lesions of the parathyroid glands are characteristic in patients with the MEN 1 syndrome; however, patients can develop parathyroid carcinomas very rarely. This report presents a clinical case of the MEN 1 syndrome: a 39-year-old woman underwent surgery for carcinoma of two parathyroid glands as well as was treated for pituitary prolactinoma, which caused infertility, and malignant insulinoma; the patient had multiple subcutaneous lipomas as well. Genetic analysis revealed a novel germline mutation in the MEN1 gene - a nucleotide insertion at codon 43 in exon 2 (c.129insA), which caused the occurrence of the MEN1 syndrome. The clinical case of the MEN 1 syndrome presented here is relevant in gathering the data on etiopathogenesis of not only MEN 1 syndrome, but an extremely rare pathology - parathyroid carcinoma - as well.

RESUMO

OBJECTIVE: The aim was to investigate the rates of respiratory and sleep disturbances in infants whose mothers experienced amniocentesis. MATERIAL AND METHODS: Infants whose mothers have undergone midterm amniocentesis (between 16 and 20 weeks) and no invasive procedure (controls) were enrolled. RESULTS: The study analyzed 50 infants whose mothers have undergone amniocentesis (amniocentesis group) and 47 controls. Amniocentesis group had higher incidence of sleep disturbances: 30 cases (60 %), compared with 11 controls (23.4 %) (P = 0.001). In the amniocentesis group there were 7 children (14 %) with asthma, while in the control group, asthma was confirmed in 1 child (2.1 %) (P = 0.032). CONCLUSION: Our data triggers the hypothesis that associations between midterm amniocentesis, child's asthma and sleep disturbances may exist. These preliminary results reveal the importance of further studies and the need for the analysis of long term effects of invasive testing.

RESUMO

The recognition of bacterial lipopolysaccharide (LPS) is principally mediated by either membrane-bound or soluble form of the glycoprotein CD14 and CD14-associated signal transducer, toll-like receptor 4 (TLR4). Recent findings indicate that the serine protease inhibitor, alpha1-antitrypsin (AAT), may not only afford protection against proteolytic injury, but may also neutralize microbial activities and affect regulation of innate immunity. We postulated that AAT affects monocyte responses to LPS by regulating CD14 expression and soluble CD14 release. Here we show that a short-term (up to 2h) monocyte exposure to AAT alone or in combination with LPS leads to a remarkable induction of CD14 levels. In parallel, a short-term (2h) cell exposure to AAT/LPS significantly enhances LPS-induced NF kappaB (p50 and p65) activation in conjunction with increased TNFalpha, IL-1 beta and IL-8 release. In contrast, longer term incubation (18 h) of monocytes with combined AAT/LPS results in a significant reduction in expression of both CD14 and TLR4, inhibition of LPS-induced TNFalpha, IL-1 beta and IL-8 mRNA and protein expression. These findings provide evidence that AAT is an important regulator of CD14 expression and release in monocytes and suggest that AAT may be involved in LPS neutralization and prevention of over-activation of monocytes in vivo.

RESUMO

In patients with MTHFR (methylenetetrahydrofolate reductase) mutations and hyperhomocysteinemia, recurrent pregnancy loss is a frequent feature. The aim of the study was to evaluate the impact of folic acid, vitamins B6 and B12 supplementation for the lowering of total homocysteine concentrations and pregnancy. 16 patients who had had 3 or more miscarriages and MTHFR mutations were used in the study. They received methylfolate (5mg/day), vitamin B6 (50mg/day) and vitamin B12 (1mg/week). Supplementation induced a decrease in homocysteine from 19.4±5.3µmol/L to 6.9±2.2µmol/L after folate supplementation (p<0.05). During one year 7 women became pregnant and delivered. Two women delivered from the homozygous C677T mutations group (7 patients) and combined heterozygous C677T/A1298C mutations group (5 patients), while 3 deliveries were in A1298C homozygous mutations group (4 patients). In conclusion, supraphysiologic methylfolate, vitamins B6 and B12 supplementation in woman with MTHFR mutations has a beneficial effect on pregnancy outcome.

RESUMO

The recent introduction of cell-free DNA (cfDNA)-based noninvasive prenatal testing (NIPT) offers pregnant women a more accurate method than traditional serum screening methods for detecting fetal aneuploidies. Clinical trials have demonstrated the efficacy of NIPT for Down, Edwards and Patau syndromes. However NIPT approaches that take advantage of single-nucelotide polymorphism (SNP) information potentially allow the identification of triploidy, chromosomal microdeletion syndromes and other unusual genetic variants. To highlight this approach of NIPT we present a rare case of confined placental X chromosome monosomy mosaicism that was prenatally suspected with a single-nucleotide polymorphism-based noninvasive prenatal test. The results of invasive tests (amniocentesis) showed small proportion of X chromosome mosaicism (45, X[5]/46, XX[95]). After birth karyotype of the girl revealed no abnormalities (46 XX), confirming that mosaicism was limited to the placenta. These results highlight the need of patient's informed consent and thorough pretest and postest counseling to ensure that they understand the limitations and advantages of the tests and the implications of the resultss.


La reciente introducción de las pruebas prenatales no invasivas (NIPT, por sus siglas en inglés) basadas en el ADN libre ofrece un método más preciso que los métodos tradicionales de detección en el suero materno para identificar aneuploidías fetales. La eficacia de las pruebas NIPT para detectar los síndromes de Down, Edwards y Patau se ha demostrado en ensayos clínicos. Sin embargo, los enfoques de las pruebas NIPT que aprovechan la información sobre el polimorfismo de un solo nucleótido (SNP, por sus siglas en inglés) tienen el potencial de identificar triploidías, síndromes de microdeleción cromosómica y otras variantes genéticas no habituales. Para destacar este enfoque de las pruebas NIPT, se presenta un caso poco frecuente de monosomía del cromosoma X debido a mosaicismo confinado a la placenta, del que había una sospecha prenatal por el resultado de una prueba prenatal no invasiva basada en el polimorfismo de un solo nucleótido. Los resultados de las pruebas invasivas (amniocentesis) mostraron una pequeña proporción de mosaicismo del cromosoma X (45, X[5]/46, XX[95]). Después del nacimiento, el cariotipo de la niña no reveló anomalías (46 XX), lo que confirmó que el mosaicismo se limitaba a la placenta. Estos resultados ponen de manifiesto la necesidad del consentimiento informado de la paciente, y del minucioso asesoramiento anterior y posterior a las pruebas, para garantizar que comprenda las limitaciones y las ventajas de dichas pruebas, y las repercusiones de los resultados.

RESUMO

Objetivo. Investigar las tasas de trastornos respiratorios y del sueño en los niños cuyas madres se sometieron a una amniocentesis. Materiales y métodos. Se incluyó a niños cuyas madres se sometieron a una amniocentesis en el segundo trimestre (entre las 16 y las 20 semanas) y otros sin procedimiento invasivo (controles). Resultados. Se anallizó a 50 niños en el grupo de amniocentesis y a 47 controles. Hubo mayor incidencia de trastornos del sueño en el grupo de amniocentesis: 30 casos (60 %) frente a 11 controles (23,4 %) (p = 0,001). En el grupo de amniocentesis, 7 niños (14%) tenían asma; en el grupo de referencia, 1 niño (2,1 %) (p = 0,032).Conclusión. Podría haber una asociación entre la amniocentesis en el segundo trimestre, el asma y los trastornos del sueño en los niños. Se requieren estudios futuros y analizar los efectos a largo plazo de las pruebas invasivas.


Objective. The aim was to investigate the rates of respiratory and sleep disturbances in infants whose mothers experienced amniocentesis.Material and methods. Infants whose mothers have undergone midterm amniocentesis (between 16 and 20 weeks) and no invasive procedure (controls) were enrolled.Results. The study analyzed 50 infants whose mothers have undergone amniocentesis (amniocentesis group) and 47 controls. Amniocentesis group had higher incidence of sleep disturbances: 30 cases (60 %), compared with 11 controls (23.4 %) (P = 0.001). In the amniocentesis group there were 7 children (14 %) with asthma, while in the control group, asthma was confirmed in 1 child (2.1 %) (P = 0.032).Conclusion. Our data triggers the hypothesis that associations between midterm amniocentesis, child's asthma and sleep isturbances may exist. These preliminary results reveal the importance of further studies and the need for the analysis of long term effects of invasive testing.

RESUMO

BACKGROUND: An increased incidence of serum alpha-1 antitrypsin deficiency has been reported in patients with chronic obstructive pulmonary disease, but has not been well proven in association with spontaneous pneumothorax. The aim of our study was to evaluate frequency of alpha-1 antitrypsin deficiency in subjects with spontaneous pneumothorax. METHODS: 39 patients with the diagnosis of spontaneous pneumothorax and 100 age- and sex-matched control subjects were included in the study. Alpha-1 antitrypsin concentrations were determined by nephelometry, Serum qualitative Z antitrypsin variant was analyzed using commercial ELISA kits and alpha-1 antitrypsin phenotyping was carried out by means of isoelectric focusing. RESULTS: AAT deficiency phenotypes were detected in 3 (7.7%) patients with spontaneous pneumothorax, and only in 1 (1%) case in the control group. However, the observed differences did not reach statistical significance due to the considerable size disproportion between groups. The mean serum alpha-1 antitrypsin level was significantly higher in patients with spontaneous pneumothorax (1.53 +/- 0.23 g/l) than controls (1.34 +/- 0.37 g/l) (p = 0.03). CONCLUSIONS: Preliminary data confirm the clinical importance of alpha-1 antitrypsin deficiency phenotypes in patients with spontaneous pneumothorax and the need to screen them for alpha1-antitrypsin deficiency.

RESUMO

Kartagener's syndrome is a rare autosomal-recessive genetic disease with progressive damage of the respiratory system and situs inversus. Although the management of patients with Kartagener's syndrome remains uncertain and evidence is limited, it is important to follow up these patients with an adequate and shared care system. This report presents a clinical case of Kartagener's syndrome in a 25-year-old woman. Computed tomography showed dextrocardia and bronchiectasis. Abdominal X-ray and ultrasound confirmed situs inversus totalis. After 7 years, good treatment results were achieved: lung function improved and radiological findings showed no changes. The present case discusses the complex interrelationship between the genetic variation and a proper nonspecific management of Kartagener's syndrome.

RESUMO

BACKGROUND AND OBJECTIVE: Alpha-1 antitrypsin deficiency is an underdiagnosed condition in patients with chronic obstructive pulmonary disease. Diagnosis of this genetic condition is confirmed by genetic verification of pathology, but for screening purposes quantitative methods can be useful. The aim of our study was to evaluate sensitivity and specificity of quantitative methods for alpha-1 antitrypsin deficiency detection. METHODS: Serum alpha-1 antitrypsin concentrations from patients (n = 1167) with chronic obstructive pulmonary disease, defined according to the GOLD criteria, were analysed by nephelometry, alpha-1 antitrypsin genotype was determined by means of isoelectric-focusing. RESULTS: Eight severe alpha-1 antitrypsin deficiency genotypes in homozygous type (ZZ) and 40 in heterozygous genotype (-Z) were identified. Calculated sensitivity of quantitative alpha-1 antitrypsin measurement by nephelometry for heterozygous PI*Z allele is 45% and for homozygous ZZ genotype is 88%. Specificity of quantitative alpha-1 antitrypsin deficiency determining analysis is 99%. CONCLUSIONS: A case detection program of alpha-1 antitrypsin deficiency in patients with chronic obstructive pulmonary disease using quantitative methods is specific, but due to limited sensitivity should be used only in screening programs.

RESUMO

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) has been recently defined as a systemic pulmonary inflammatory disease, and congenital α1 antitrypsin deficiency is one of the well-established genetic risk factors for chronic obstructive pulmonary disease. The aim of our study was to evaluate the possible associations of α1 antitrypsin with inflammatory markers - CRP, sCD14, TNF-α, sTNFR-1, and sTNFR-2 - in patients with COPD with different α1 antitrypsin genotypes. MATERIAL AND METHODS: Serum biomarkers from patients (n = 355) with COPD, defined according to the GOLD criteria, were analyzed using commercial ELISA kits; α1 antitrypsin concentrations were determined by nephelometry, and α1 antitrypsin phenotyping was carried out by means of isoelectric focusing. RESULTS: No significant differences in CRP, TNF-α, sTNFR-1, sTNFR-2, and sCD14 levels were found comparing COPD patients with different genotypes. In patients without α1 antitrypsin deficiency (PI*MM), a significant negative correlation between lung function (FEV(1)) and serum α1 antitrypsin (r = -0.522, p = 0.03) and CRP concentration (r = -0.590, p = 0.011) was detected. The level of α1 antitrypsin positively correlated with: a) CRP concentration (r = 0.671, p = 0.005), b) sCD14 (r = 0.510, p = 0.008) and c) sTNFR-1 (r = 0.567, p = 0.007). CONCLUSIONS: In patients without α1 antitrypsin deficiency, the positive association of α1 antitrypsin concentration with CRP, sCD14, and sTNFR-1 and the negative association with FEV(1) show the importance of α1 antitrypsin as a marker of systemic inflammation.
