Objective: To evaluate the treatment compliance of patients with paracoccidioidomycosis. Methods: We studied 188 patients with paracoccidioidomycosis admitted to a tertiary referral hospital in the Central-West Region of Brazil from 2000 to 2010, to assess their compliance to treatment. In order to be considered compliant, patients needed to present two established criteria: (1) receive medicines from the pharmacy, and (2) achieve a self-reported utilization of at least 80% of the dispensed antifungal compounds prescribed since their previous appointment. Results: Most patients were male (95.7%), had the chronic form of the disease (94.2%), and were treated with cotrimoxazole (86.2%). Only 44.6% of patients were treatment compliant. The highest loss to follow-up was observed in the first 4 months of treatment (p < 0.02). Treatment compliance was higher for patients with than for those without pulmonary involvement (OR: 2.986; 95%CI 1.351-6.599), and higher for patients with than without tuberculosis as co-morbidity (OR: 2.763; 95%CI 1.004-7.604). Conclusions: Compliance to paracoccidioidomycosis treatment was low, and the period with the highest loss to follow-up corresponds to the first four months. Pulmonary paracoccidioidal involvement or tuberculosis comorbidity predicts a higher compliance to paracoccidioidomycosis therapy.

On HRCT scans, lung cysts are characterized by rounded areas of low attenuation in the lung parenchyma and a well-defined interface with the normal adjacent lung. The most common cystic lung diseases are lymphangioleiomyomatosis, Langerhans cell histiocytosis, and lymphocytic interstitial pneumonia. In a retrospective analysis of the HRCT findings in 50 patients diagnosed with chronic paracoccidioidomycosis, we found lung cysts in 5 cases (10%), indicating that patients with paracoccidioidomycosis can present with lung cysts on HRCT scans. Therefore, paracoccidioidomycosis should be included in the differential diagnosis of cystic lung diseases.

Primary infection with Paracoccidioides brasiliensis has rarely been observed. A 28-year-old male patient presented with a three-month history of fever, respiratory symptoms and malaise. Chest X-rays revealed bilateral apical infiltrates, right pleuritis and hilar lymphadenomegaly. The patient presented with leukocytosis, severe eosinophilia and increasing titers of anti-P. brasiliensis antibodies in serum. To our knowledge, this is the first report of the primary pulmonary lymph node complex of paracoccidioidomycosis accompanied by hypereosinophilia and affecting a previously healthy adult.

Objective: To determine the compliance with tuberculosis treatment among patients enrolled the tuberculosis control program in the city of Carapicuíba, Brazil, before and after the implementation of the directly observed treatment, short-course (DOTS) strategy. Methods: A retrospective historical cohort study of operational aspects based on records of attendance and treatment evolution of patients in self-administered treatment (SAT) and of those submitted to DOTS. Monthly treatment outcome tables were created, and the probability of compliance with the treatment was calculated for both groups of patients. Results: A total of 360 patients with tuberculosis met the inclusion criteria: 173 (48.1%) in the SAT group; and 187 (51.9%) in the DOTS group. Treatment compliance was 6.1% higher in the DOTS group than in the SAT group. The proportion of patients completing the six months of treatment was 91.6% and 85.5% in the DOTS group and in the SAT group, respectively. Conclusions: The results of this study show that DOTS can be successfully implemented at primary health care clinics. In this population of patients, residents of a city with low incomes and a high burden of tuberculosis infection, DOTS was more effective than was SAT.

Paracoccidioidomycosis is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis. The disease is restricted to Latin America. It is the principal systemic mycosis in Brazil, with higher incidences in the southern, southeastern and central regions. The disease is acquired by inhaling fungal propagules. In endemic areas, the primary infection occurs during childhood and involves the immune system. The most common chronic form of paracoccidioidomycosis in adults is the multifocal form, in which there is dissemination to the lungs, lymph nodes, skin and mucosae. This form of the disease has a chronic progression, and the diagnosis is typically delayed. Cough, dyspnea and weight loss due to cutaneous and mucosal lesions are evident and are the principal complaints reported by paracoccidioidomycosis patients. Chest X-rays reveal diffuse reticulonodular infiltrates, which are more evident in the upper lobes. The etiologic diagnosis is based on the identification of P. brasiliensis in clinical specimens, such as lymph node aspirates or BAL fluid, by direct microscopy and culture. Histopathological testing of tissue samples reveals the thick birefringent cell wall of the fungus and the typical pattern of multiple budding around the mother cell. Double agar gel immunodiffusion is useful for the diagnosis when the fungus cannot be detected through mycological tests. Although paracoccidioidomycosis is most often treated with the sulfamethoxazole-trimethoprim combination, itraconazole is preferable. Amphotericin B is used in severe cases.

Objective: To evaluate treatment compliance and use of inhaled medications of patients with asthma receiving complementary pharmaceutical care. Methods: A controlled prospective parallel study involving a study group and a control group. We selected 60 patients with persistent asthma and using metered-dose inhalers (MDIs), dry powder inhalers (DPIs) or both. The patients were evaluated three times over 60 days. Instructions were provided to the patients in the study group at all visits but only at the first visit to those in the control group. The patients using < 80% or > 120% of the total number of prescribed doses were classified as noncompliant. The inhalation technique was quantified by a scoring system. A satisfactory technique was defined as a score higher than 7 (maximum, 9) for MDIs and higher than 4 (maximum, 5) for DPIs. Results: The final study sample comprised 28 study group patients and 27 control group patients, of whom 18 (64.3%) and 20 (74.7%), respectively, were considered treatment compliant. From the first to the third visits, there were increases, in the study and control groups, in the median MDI-use score (from 3 [range, 0-5] to 8 [range, 8-9]; p < 0.001; and from 5 [range, 2-6] to 7 [range, 6-8]), as well as in the median DPI-use score (from 3 [range, 2-4] to 5 [range, 4-5] and from 3 [range, 2-4] to 4 [range, 3-5]). Conclusions: The counseling provided by the pharmacist to the patient was important to assist in the implementation of the appropriate inhalation technique, especially for MDI use.

Objective: To analyze the association between paracoccidioidomycosis (Pcm) and cancer in a series of 25 cases and to review the literature on this topic. Methods: A retrospective review of 25 cases diagnosed with Pcm and cancer, retrieved from a series of 808 consecutive adult patients diagnosed with Pcm based on tests conducted in the Mycology Laboratory of the Santa Casa Complexo Hospitalar, in the city of Porto Alegre, Brazil, between 1972 and 2007. The diagnosis of Pcm was confirmed by means of direct microscopic examination, histopathological examination or immunodiffusion test. All cancer cases were confirmed by histopathological or cytopathological examination. Results: Respiratory symptoms were the principal complaints of the patients evaluated. Pulmonary involvement predominated, followed by skin and lymph node involvement. The most prevalent tumor was bronchial carcinoma, in 15 patients, followed by other types of carcinoma, and 1 patient had Hodgkin's lymphoma. In 16 patients (64%), the site of the Pcm was the same as that of the tumor. In most cases, Pcm treatment consisted of the isolated administration of sulfanilamide, sulfamethoxazole-trimethoprim, ketoconazole, itraconazole or amphotericin B. The most common treatment for cancer was surgery, followed by radiotherapy and chemotherapy. Of the 25 patients, 12 were cured of Pcm, and 4 died. In 9 patients, the final outcome was unknown. In the general population of the area under study, the prevalence of lung cancer was significantly higher in smokers with Pcm than in smokers without Pcm (p < 0.001). Conclusions: A diagnosis of Pcm appears to increase the risk of lung cancer.

Objective: To determine the rate of compliance with preventive treatment of moderate and severe persistent asthma. Methods: Physicians at various medical centers across the country were invited to nominate patients for participation in the study. Inclusion criteria were being over the age of 12 and presenting moderate or severe persistent asthma. Participating patients received salmeterol/fluticasone 50/250 µg by dry powder inhaler for 90 days and were instructed to return the empty packages at the end of the study as a means of determining the total quantity used. In order to evaluate compliance, a member of the research team contacted each patient via telephone at the study outset and again at the end of the 90-day study period. Asthma patients were considered compliant with the treatment if they used at least 85% of the prescribed dose. The following variables were studied: gender, age, race, marital status, years of schooling, smoking habits, other atopic conditions, comorbidities, asthma severity, use of other medication and number of hospital admissions for asthma. Results: A total of 131 patients from fifteen states were included. The overall rate of compliance was found to be 51.9%. There was a significant difference in compliance in relation to asthma severity: compliance was greater among patients with severe persistent asthma than among those with moderate persistent asthma (p = 0.02). There were no statistically significant differences among any of the other variables. Conclusion: The overall rate of compliance with maintenance treatment of asthma was low.

Objective: To evaluate the frequency of the real association between paracoccidioidomycosis (PCM) and tuberculosis (TB) as well as the rate of previous TB misdiagnosis in individuals with PCM among the patients treated in the Pulmonology Division of the State University of Campinas Hospital das Clínicas, Campinas, Brazil. Methods: A retrospective study of 227 adult patients with PCM (chronic form) treated between 1980 and 2005. Results: Of the 227 patients studied, 36 (15.8%) had been previously treated for TB. However, only 18 (7.9%) presented positive sputum smear microscopy results. The remaining 18 (7.9%) neither presented positive sputum smear microscopy nor showed improvement after receiving specific anti-TB treatment. Conclusion: Although the existence of an association between PCM and TB has been documented in the literature, misdiagnosis is common due to the superimposition of and the similarity between their clinical and radiographic presentations, thereby warranting the need for bacteriological diagnosis before initiating specific treatment.

The incidence of pulmonary fungal infections is very low in Uruguay, and such infections typically affect immunocompromised patients. We report the case of an immunocompetent patient presenting with a two-month history of cough, dyspnea, and fever. The patient resided in a rural area. Imaging tests revealed extensive pneumonitis and pulmonary fibrosis. On the basis of direct mycological examination, culture, and serological testing, we made a diagnosis of concomitant histoplasmosis and paracoccidioidomycosis. The patient presented arterial hypotension that was diagnostic of adrenocortical insufficiency. Although the pulmonary fibrosis and pneumonia were irreversible, the clinical condition of the patient improved after antifungal treatment. This was an exceptional case of two pulmonary fungal infections occurring simultaneously in the same patient.

Objective: To compare the frequency of unfavorable outcome (death or default and treatment failure) between tuberculosis (TB)/HIV co-infected patients treated for TB after laboratory confirmation of the diagnosis and TB/HIV co-infected patients who were so treated without diagnostic confirmation. Methods: A retrospective cohort of TB/HIV co-infected patients who started TB treatment between July of 2002 and June of 2004 at an HIV/AIDS referral center in Recife, Brazil. The main exposure variable, laboratory confirmation of TB, was adjusted for three different sets of variables: sociodemographic variables; HIV/AIDS-related variables; and TB-related variables. In order to evaluate the statistical significance of the results, we calculated odds ratios, with 95% confidence intervals, and p values (from chi-square tests and likelihood ratio tests). Results: A total of 262 patients were studied. No association was found between laboratory confirmation of the diagnosis of TB at treatment outset and unfavorable outcome, even after adjustment for confounders. In the final multiple logistic regression model, the following variables remained: the presence of other opportunistic diseases; CD4 lymphocyte count below 50 cells/mm3; viral load between 10,000 and 100,000 copies/mL; dyspnea; the disseminated form of TB; and change in the TB treatment regimen due to adverse reactions or intolerance. Conclusions: Our results suggest that TB treatment in TB/HIV co-infected patients without etiologic confirmation of TB, at the discretion of experienced physicians in referral centers, did not increase the risk of unfavorable outcomes. In addition, it allowed the identification of groups that should be closely monitored due to a greater risk of unfavorable outcomes.

Objective: To determine, through home visits, the rate of compliance with environmental control measures in the homes of children with asthma. Methods: This study involved 98 asthma patients between the ages of 4 and 15. The parents of those children and adolescents received instruction in how to carry out environmental control measures and were encouraged to perform such measures continuously for a period of 90 days. Home visits, which included direct inspection of the domicile and administration of a questionnaire, were made before and after this 90-day period. In cases of noncompliance, parents were asked to explain why they did not carry out the control measures. Statistical analysis was performed using the McNemar test. Results: Overall compliance with the various items studied was 11.1%, ranging from -4.1% (for curtain control, p = 0.63) to 22.6% (for stuffed toys, p < 0.001). Passive smoking was reduced to 9.7% (p = 0.02). Among the families studied, the mean monthly income was 2.5 times the national minimum wage. When asked why they had not adopted the recommended measures, noncompliant parents gave, among others, the following explanations: "economic hardship" (60.1%); "the measures were too difficult to carry out" (6.1%); "nonparticipation of the father" (4%); and "lack of time on the part of the mother" (4%). Conclusion: Environmental control measures were carried out sporadically, possibly reflecting the influence of socioeconomic and cultural factors.

Objective: To characterize the clinical and histological profile, as well as treatment patterns, of patients with early-stage, locally advanced (LA), or advanced/metastatic (AM) lung cancer, diagnosed between 2000 and 2014, in Brazil. Methods: This was an analytical cross-sectional epidemiological study employing data obtained for the 2000-2014 period from the hospital cancer registries of two institutions in Brazil: the José Alencar Gomes da Silva National Cancer Institute, in the city of Rio de Janeiro; and the São Paulo Cancer Center Foundation, in the city of São Paulo. Results: We reviewed the data related to 73,167 patients with lung cancer. The proportions of patients with early-stage, LA, and AM lung cancer were 13.3%, 33.2%, and 53.4%, respectively. The patients with early-stage lung cancer were older and were most likely to receive a histological diagnosis of adenocarcinoma; the proportion of patients with early-stage lung cancer remained stable throughout the study period. In those with LA lung cancer, squamous cell carcinoma predominated, and the proportion of patients with LA lung cancer decreased significantly over the period analyzed. Those with AM lung cancer were younger and were most likely to have adenocarcinoma; the proportion of patients with AM lung cancer increased significantly during the study period. Small cell carcinoma accounted for 9.2% of all cases. In our patient sample, the main treatment modality was chemotherapy. Conclusions: It is noteworthy that the frequency of AM lung cancer increased significantly during the study period, whereas that of LA lung cancer decreased significantly and that of early-stage lung cancer remained stable. Cancer treatment patterns, by stage, were in accordance with international guidelines.

Abstract Objective: To determine the rate of adherence to treatment with inhaled corticosteroids in patients with severe asthma, to identify predictive factors for adherence and to evaluate the relationship between adherence to treatment and parameters of clinical and functional response. Methods: Prospective cohort study of patients enrolled in the Program for the Control of Asthma and Allergic Rhinitis in the state of Bahia, Brazil. The study comprised 160 patients with severe asthma, monitored for 180 days in order to evaluate adherence (dependent variable) to the prescribed inhaled corticosteroid. Independent variables were assessed at baseline and for a six-month follow-up period by means of interviews and the completion of a standardized questionnaire. Patients recorded the missed doses in a diary. Results: Of the 160 patients, 158 completed the study. Adherence rate was 83.8%. Of the 158 patients, 112 (70.9%) were considered adherent (cut-off point: 80% of prescribed doses administered). There was a significant association between asthma control and adherence to treatment. Predictors of poor adherence were adverse effects, living far from the referral center, limited resources to pay for transportation and dose schedule. Other factors, such as depressive symptoms, religion and economic status, were not associated with poor adherence. Conclusions: Adherence to asthma treatment was high and was associated with the clinical response to treatment, in a sample of patients with severe asthma enrolled in a public program that provides free medication and the assistance of a multiprofessional specialized team in a referral center.

Objective: Early tuberculosis diagnosis and treatment are determinants of better outcomes and effective disease control. Although tuberculosis should ideally be managed in a primary care setting, a proportion of patients are diagnosed in emergency facilities (EFs). We sought to describe patient characteristics by place of tuberculosis diagnosis and determine whether the place of diagnosis is associated with treatment outcomes. A secondary objective was to determine whether municipal indicators are associated with the probability of tuberculosis diagnosis in EFs. Methods: We analyzed data from the São Paulo State Tuberculosis Control Program database for the period between January of 2010 and December of 2013. Newly diagnosed patients over 15 years of age with pulmonary, extrapulmonary, or disseminated tuberculosis were included in the study. Multiple logistic regression models adjusted for potential confounders were used in order to evaluate the association between place of diagnosis and treatment outcomes. Results: Of a total of 50,295 patients, 12,696 (25%) were found to have been diagnosed in EFs. In comparison with the patients who had been diagnosed in an outpatient setting, those who had been diagnosed in EFs were younger and more socially vulnerable. Patients diagnosed in EFs were more likely to have unsuccessful treatment outcomes (adjusted OR: 1.54; 95% CI: 1.42-1.66), including loss to follow-up and death. At the municipal level, the probability of tuberculosis diagnosis in EFs was associated with low primary care coverage, inequality, and social vulnerability. In some municipalities, more than 50% of the tuberculosis cases were diagnosed in EFs. Conclusions: In the state of São Paulo, one in every four tuberculosis patients is diagnosed in EFs, a diagnosis of tuberculosis in EFs being associated with poor treatment outcomes. At the municipal level, an EF diagnosis of tuberculosis is associated with structural and socioeconomic indicators, indicating areas for improvement.

Objective: To evaluate the association between adherence to treatment and mortality among Chronic Obstructive Pulmonary Disease (COPD) patients treated in the Brazilian public health system. Methods: This is cohort study of moderate-to-severe COPD patients monitored in a public pharmaceutical care-based Disease Management Program (DMP). All subjects who died one year after the beginning of the cohort were age-matched with those who remained alive at the end of the cohort period. Treatment adherence was measured through pharmacy records. Patients who received at least 90% of the prescribed doses were considered adherent to treatment. Results: Of the 333 patients (52.8% age = 65 years, 67.9% male), 67.3% were adherent to treatment (adherence rate, 87.2%). Mortality was associated with lack of adherence (p = 0.04), presence of symptoms (mMRC = 2) and COPD treatment use. The death was associated with non-adherence, presence of symptoms and previous hospitalization. After adjustment, non-adherent patients to treatment were almost twice times likely to die compared to those adherents (Hazard Ratio (HR) 1.86; CI 1.16-2.98, p = 0.01). Conclusion: Non-adherence to treatment was associated with higher mortality among moderate-to-severe COPD patients treated in the Brazilian public health system. Strategies to monitor and optimize adherence should be strengthened to reduce COPD-related mortality.

Objective: To analyze factors predictive of noncompliance with pulmonary tuberculosis treatment. Methods: A historical cohort study involving 481 of the 529 active tuberculosis patients registered with the Tuberculosis Control Program in the city of Cuiabá, located in the state of Mato Grosso, during the 1998-2000 period. Data were obtained by analyzing medical charts and registration records. In the bivariate analysis, the chi-square test was used to calculate noncompliance rate ratios (relative risk), 95% confidence intervals were determined, and Fisher's exact test was used. The choice to estimate the rate of incidence was the method of density and a multivariate logistic regression model was constructed in order to identify the variables that were most predictive of noncompliance, using a level of statistical significance of p < 0.05. Results: The global rate of incidence was 27.3%, equivalent to 5.1 noncompliant patients/100 patients/month, increasing in the second and third months of treatment. In the final logistic regression model, the following were considered predictors of noncompliance: unsupervised treatment (odds ratio: 2.58; 95% confidence interval: 1.64 - 4.06; p < 0.001); having been treated during the 1998-1999 period (odds ratio: 1.43; 95% confidence interval: 1.14 - 1.80; p = 0.002); being male (odds ratio: 1.39; 95% confidence interval: 1.10 - 1.76; p = 0.005) and having been out of compliance with previous treatment regimes (odds ratio: 1.37; 95% confidence interval: 1.06 - 1.78; p < 0.017). Conclusion: The results indicate an elevated incidence of noncompliance and show that unsupervised treatment, year in which treatment was received, male gender and prior noncompliance were predictors of future noncompliance.

Objective: To analyze the association between clinical/epidemiological characteristics and outcomes of tuberculosis treatment in patients with concomitant tuberculosis and chronic kidney disease (CKD) in Brazil. Methods: We used the Brazilian Ministry of Health National Case Registry Database to identify patients with tuberculosis and CKD, treated between 2007 and 2011. The tuberculosis treatment outcomes were compared with epidemiological and clinical characteristics of the subjects using a hierarchical multinomial logistic regression model, in which cure was the reference outcome. Results: The prevalence of CKD among patients with tuberculosis was 0.4% (95% CI: 0.37-0.42%). The sample comprised 1,077 subjects. The outcomes were cure, in 58%; treatment abandonment, in 7%; death from tuberculosis, in 13%; and death from other causes, in 22%. The characteristics that differentiated the ORs for treatment abandonment or death were age; alcoholism; AIDS; previous noncompliance with treatment; transfer to another facility; suspected tuberculosis on chest X-ray; positive results in the first smear microscopy; and indications for/use of directly observed treatment, short-course strategy. Conclusions: Our data indicate the importance of sociodemographic characteristics for the diagnosis of tuberculosis in patients with CKD and underscore the need for tuberculosis control strategies targeting patients with chronic noncommunicable diseases, such as CKD.
