QUALITY OF LIFE EVALUATION IN CELIAC PATIENTS FROM SOUTHERN BRAZIL

BACKGROUND Restrictions imposed by the gluten-free diet generate large changes in the daily habits of the celiac patient, causing a negative impact on quality of life. OBJECTIVE This study aimed to evaluate the quality of life of patients with celiac disease on a capital in Southern Brazil. METHODS Patients older than 18 years were included, with confirmed celiac disease for at least 60 days in the period from June to October 2013. A validated questionnaire, with specific questions to assess the patients quality of life celiac was applied. A total score ranged from 20 to 100 points; the higher the score, worse quality of life. RESULTS A total of 103 questionnaires were evaluated, 96 (93.2%) female, with average score 56.6±12.35 (28 to 88 points). The comparison between the questionnaire scores and family income was not significant (P=0.139). Patients diagnosed less than 1 year have poorer quality of life than those with more than 10 years (P=0.063). Patients older than 60 years had better quality of life compared with the younger ones (P=0.04). CONCLUSION There was no association between quality of life and factors such as family income, length of diet and age at diagnosis. Chronological age greater than 60 years has positively influenced the quality of life of celiac patients.

Fecal calprotectin: : levels for the ethiological diagnosis in Brazilian patients with gastrointestinal symptoms

BACKGROUND Determination of fecal calprotectin can provide an important guidance for the physician, also in primary care, in the differential diagnosis of gastrointestinal disorders, meanly between inflammatory bowel diseases and irritable bowel syndrome. Objectives The aims of the present study were to prospectively investigate, in Brazilian adults with gastrointestinal complaints, the value of fecal calprotectin as a biomarker for the differential diagnosis between functional and organic disorders and to correlate the concentrations with the activity of inflammatory bowel diseases. METHODS The study included consecutive patients who had gastrointestinal complaints in which the measurement levels of fecal calprotectin were recommended. Fecal calprotectin was measured using a Bühlmann (Basel, Switzerland) ELISA kit. RESULTS A total of 279 patients were included in the study, with median age of 39 years (range, 18 to 78 years). After clinical and laboratorial evaluation and considering the final diagnosis, patients were allocated into the following groups: a) Irritable Bowel Syndrome: 154 patients (102 female and 52 male subjects). b) Inflammatory Bowel Diseases group: 112 patients; 73 with Crohns disease; 38 female and 35 male patients; 52.1% (38/73) presented active disease, and 47.9% (35/73) had disease in remission and 39 patients with ulcerative colitis;19 female and 20 male patients; 48.7% (19/39) classified with active disease and 49.3% (20/39) with disease in remission. A significant difference (P<0.001) was observed between the median value of fecal calprotectin in Irritable Bowel Syndrome group that was 50.5 µg/g (IQR=16 - 294 µg/g); 405 µg/g (IQR=29 - 1980 µg/g) in Crohns disease patients and 457 µg/g (IQR=25 - 1430 µg/g) in ulcerative colitis patients. No difference was observed between the values found in the patients with Crohns disease and ulcerative colitis. Levels of fecal calprotectin were significantly lower in patients with inflammatory bowel diseases in remission when compared with active disease (P<0.001). CONCLUSIONS The present study showed that the determination of fecal calprotectin assists to differentiate between active and inactive inflammatory bowel diseases and between inflammatory bowel diseases and irritable bowel syndrome.

Celiac disease screening in Brazilian patients with osteoporosis

OBJECTIVE To analyze if it is worthwhile to screen Brazilian osteoporotic patients for celiac disease (CD). SUBJECTS AND METHODS One hundred patients with osteoporosis and 97 controls were evaluated for IgA-EmA (IgA anti-endomysial antibodies) by indirect immunofluorescence method and IgG-anti-tTG (tissue transglutaminase) by ELISA assay. Positive patients were invited to have gastrointestinal endoscopy with jejunal biopsy. RESULTS Two patients had positive IgG-anti-tTG test and one of them also showed positive IgA-EmA. Only the latter had a positive duodenal biopsy for CD. None of the controls were positive for either auto-antibodies. CONCLUSION We observed low prevalence of CD in osteoporotic Brazilian patients. This finding does not support routine screening for CD in patients with osteoporosis in our geographic region.

Blood discard rate in a blood center in Curitiba – Brazil. Ten years of study

INTRODUCTION Development of technologies to reduce transfusion risks of infectious diseases is a major characteristic of hemotherapy. Thus, each donation undergoes clinical and serological screening tests to ensure the donated blood do not offer risks to the receiver. OBJECTIVE Evaluate the prevalence of positive serology in blood donations rejected by Hemobanco (Curitiba - PR) in the period ranging from January 2003 to December 2012. METHODOLOGY During the period studied, we observed the total number of donations and its division according to gender. We also analyzed the number of rejected donations due to seropositivity, considering the diseases investigated routinely in blood banks in Brazil, and the frequency of discards according to age groups. RESULTS Within the period studied, 399,280 donations were performed. 62.0% donors were male. Comparing 2003 to 2012, we noticed a significant decrease of discards, from 10.2% to 5.0%, respectively. There was a reduction of seropositivity for HIV, HBsAg and anti-HBc and an increase for Chagas Disease, hepatitis C, syphilis and HTLV. The age group with the highest prevalence for discards changed: it used to be the 40-59 years old group in 2003, and became the 20-39 years old group in 2012. CONCLUSION There was an increase in the number of donations in Hemobanco and a decrease in total discards due to seropositive donations. Most donors were male. The most prevalent cause of discards only amongst seropositive donation discards is seropositivity for anti-HBc. There was a significant increase of donors aged between 20 and 39 years old.

Associação entre cardiopatias congênitas e infeções graves em crianças com síndrome de Down

INTRODUCTION There is a high prevalence of congenital heart disease (CHD) in Down syndrome (DS) patients. Children with DS and CHD also present greater susceptibility to pulmonary infections than those without CHD. AIM To investigate the prevalence and types of CHD and their association with severe infections in children with DS in southern Brazil seen in a reference outpatient clinic. METHODS Children aged between six and 48 months with a diagnosis of DS were included consecutively in the period May 2001 to May 2012, and the presence of CHD and severe infections (pneumonia and sepsis) was investigated, classified and analyzed. RESULTS A total of 127 patients were included, of whom 89 (70.1%) had some type of CHD, 33 (37.7%) of them requiring surgical correction. Severe infections (pneumonia and sepsis) were seen in 23.6% and 5.5%, respectively. Of the cases of pneumonia, 70% had associated CHD (p=0.001) and of those with sepsis, 85% presented CHD (p=0.001). CONCLUSIONS Our study showed a high prevalence of CHD and its association with severe infections in children with DS seen in southern Brazil.

Epidemiological analysis of occupational dermatitis notified in Brazil in the period 2007 to 2012

BACKGROUND Occupational dermatitis affects the quality of life and productivity of workers. Studies on the subject are scarce in Brazil. It is estimated that the disease is underreported and that many affected patients do not seek health care. OBJECTIVES To conduct an epidemiological analysis of occupational dermatitis notified via SINAN in Brazil from January 2007 to December 2012; evaluate the profile of patients assisted; and check the main etiological agents involved. METHODS We analyzed the compulsory notification forms of cases of occupational dermatitis filled nationwide during January 2007 to December 2012. RESULTS During the study period 3027 cases of occupational dermatitis were notified in Brazil. In 61.4% of cases patients were men aged between 35-49 years (39.6%). The most described etiological agent was chromium (13.9%). The location of the body most affected was the hands, with 28.4% of cases. The construction sector is implicated in 28.7% of cases and domestic services by 18%. Allergic contact dermatitis is the most prevalent occupational dermatitis (20.6%) and the region with the highest number of notifications was the Midwest, with 376.4 cases per million inhabitants. CONCLUSIONS The profile of patients most affected by occupational dermatitis in Brazil during the study period was: men with elementary school, aged between 20 and 49 years old and working in the construction industry. The most common occupational dermatitis were allergic contact dermatitis caused by chromium after years of exposure, being the hands and head the parts of the body most affected.

LOW BONE MINERAL DENSITY IN BRAZILIAN PATIENTS AT DIAGNOSIS OF CELIAC DISEASE

BACKGROUND Low bone mineral density is considered an extra-intestinal manifestation of celiac disease with reduced bone mass, increased bone fragility, and risk of fractures. Celiac disease is considered a condition at high risk for secondary osteoporosis and the evaluation of bone density is very important in the clinical management of these patients. OBJECTIVE The present study aimed to investigate bone alterations in celiac patients from Curitiba, South Region of Brazil at diagnosis, correlating the findings with age and gender. METHODS Patients who were included in the study were attended to in a private office of the same physician from January 2009 to December 2013. The diagnosis of celiac disease was done through clinical, serological and histological findings. All data were collected from the medical charts of the patients. After the diagnosis of celiac disease, evaluation for low bone mineral density was requested by dual-energy X-ray absorptiometry (DEXA). DEXA bone densitometer was used to estimate low bone mineral density at the lumbar spine and femur. RESULTS A total of 101 patients, 82 (81.2%) female and 19 (18.8%) male subjects, with mean age of 39.0±3.03 years were included. At celiac disease diagnosis, 36 (35.6%) were younger than 30 years, 41 (40.6%) were between 31 and 50 years, and 24 (23.8%) were older than 50 years. Among the evaluated patients, 69 (68.3%) presented low bone mineral density, being 47% with osteopenia and 32% with osteoporosis. Patients who were older than 51 years and diagnosed with celiac disease presented low bone mineral density in 83.3% (20/24) of the cases. As expected, age influenced significantly the low bone mineral density findings. Among women, low bone mineral density was present with high frequency (60%) from 30 to 50 years. In patients diagnosed older than 60 years (n=8), all the women (n=5) and two of the three men had osteoporosis. CONCLUSION This study demonstrated that 69% of Brazilian patients with celiac disease at diagnosis had low bone mineral density, being more frequent in women older than 50 years.

Analysis of knowledge of the general population and health professionals on organ donation after cardiac death.

Objective To evaluate the knowledge and acceptance of the public and professionals working in intensive care units regarding organ donation after cardiac death. Methods The three hospitals with the most brain death notifications in Curitiba were selected, and two groups of respondents were established for application of the same questionnaire: the general public (i.e., visitors of patients in intensive care units) and health professionals working in the same intensive care unit. The questionnaire contained questions concerning demographics, intention to donate organs and knowledge of current legislation regarding brain death and donation after cardiac death. Results In total, 543 questionnaires were collected, including 442 from family members and 101 from health professionals. There was a predominance of women and Catholics in both groups. More females intended to donate. Health professionals performed better in the knowledge comparison. The intention to donate organs was significantly higher in the health professionals group (p = 0.01). There was no significant difference in the intention to donate in terms of education level or income. There was a greater acceptance of donation after uncontrolled cardiac death among Catholics than among evangelicals (p < 0.001). Conclusion Most of the general population intended to donate, with greater intentions expressed by females. Education and income did not affect the decision. The type of transplant that used a donation after uncontrolled cardiac death was not well accepted in the study population, indicating the need for more clarification for its use in our setting.

Anti-alpha-fodrin antibodies in patients with Sjögren's syndrome secondary to rheumatoid arthritis

Introduction: The Sjogrens syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration. The currently most researched antibodies for its diagnosis are anti-La and anti-Ro, which, however, have low specificity in the case of SS secondary to rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The antibodies against alpha-fodrin (AF) have been proposed to diagnose SS. Objective: In the present study, we investigated the anti-AF antibody in a group of RA patients with and without secondary SS (sSS). Methods: Were studied 90 consecutive patients with RA (48.8% of them with SS), and samples of 45 healthy volunteers. Anti-AF immunoglobulin class G (IgG) and anti-AF immunoglobulin class A (IgA) were investigated by enzyme-linked immunosorbent assay (ELISA) and were considered positive when >15 U/ml. Demographic, clinical, and serological data were obtained from chart reviews. Results: Anti-AF IgA was positive in 46/90 (51.1%) of the RA sample and 3/45 (6.7%) of controls (p < 0.001); anti-AF IgG was found in 21/90 (23.3%) of RA patients and none of controls (p = 0.037). Neither IgA nor IgG anti-AF antibodies showed significant difference in patients with and without sSS. Conclusion: In our study, anti-AF IgA and anti-AF IgG neither alloweded diagnosis of sSS in RA patients, nor marked any special clinical or serological finding.

Infections and systemic lupus erythematosus

ABSTRACT Objective To determine the incidence of infections in a population of systemic lupus erythematosus individuals and the characteristics of infections regarding original site, as well as to study the possible associations between infections and treatment. Methods An analytical retrospective study using data from medical charts of systemic lupus erythematosus patients from a single university hospital. A total of 144 patients followed up for five years were included. Data collected comprised age of patients and age at onset of lupus, sex and ethnicity, disease duration before the study period, medications, cumulative dose of prednisone, occurrence of infections and their original site. Results The most frequent infections were urinary tract infections (correlated to use of prednisone − p<0.0001 and cyclophosphamide − p=0.045), upper airways infections (correlated to use of prednisone − p=0.0004, mycophenolate mofetil − p=0.0005, and cyclosporine − p=0.025), and pneumonia (associated to prednisone − p=0.017). Conclusion Prednisone was the drug more often associated with presence of infections, pointing to the need for a more judicious management of this drug.
