Abstract

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.

 

Resumo

Objetivo: Avaliar a adesão ao tratamento de paracoccidioidomicose. Métodos: Estudo conduzido com 188 pacientes com paracoccidioidomicose atendidos em um hospital terciário na Região Centro-Oeste do Brasil, de 2000 a 2010, para avaliar adesão ao tratamento. Foram considerados aderentes pacientes que tiveram o seguinte critério: retiraram os medicamentos na farmácia e autorrelataram a utilização de, no mínimo, 80% de dispensação dos antifúngicos prescritos na última consulta. Resultados: A maioria dos pacientes era homem (95,7%), tinha a forma crônica da doença (94,2%) e foi tratada com sulfametoxazol/trimetropim (86,2%). Apenas 44,6% dos pacientes aderiram ao tratamento. A maior perda de seguimento foi observada nos primeiros 4 meses de tratamento (p < 0,02). Adesão ao tratamento foi maior em pacientes com do que sem envolvimento pulmonar (RC: 2,986; IC95% 1,351-6,6599) e maior para os pacientes com do que sem tuberculose associada (RC 2,763; IC95% 1,004-7,604). Conclusões: A adesão ao tratamento da paracoccidioidomicose foi baixa e os primeiros 4 meses constituíram o período com maior evasão. Pacientes com envolvimento paracocidióidico pulmonar ou tuberculose associada revelaram maior adesão ao tratamento da paracoccidioidomicose.

INTRODUCTION

Paracoccidioidomycosis (PCM) is a systemic mycosis caused by Paracoccidioides brasiliensis and Paracoccidioides lutzii that is endemic in Latin America.(1) Cases diagnosed in other countries are usually imported ones involving people who moved from Latin America.(1,2) In Brazil, the mortality rate for PCM is 1.45 per 1 million inhabitants, making it the eighth most common cause of mortality among chronic recurrent infectious and parasitic diseases. (3) The fatality rate is between 5 and 27%.(3,4) The main therapeutic challenges of PCM are its long duration, the high frequency of relapses and sequelae, and comorbidities. The most frequently observed comorbidities are endemic diseases such as tuberculosis, intestinal helminthiases, and cigarette smoking.(5,6) PCM treatment continues until an apparent cure is reached; the term "apparent cure" is preferred to that of "cure" because it is impossible to confirm the eradication of the fungus from the affected individual.(7) Treatment duration depends on host immunity, virulence of the isolate, Paracoccidioides sp inoculum size, and the antifungal compound used. The duration of the treatment is usually maintained until the recovery of cell-mediated immunity(8,9) to avoid reactivation of the fungal cells, which can persist as latent foci.

Compliance, i.e. the act of taking medications as prescribed, is a highly complex clinical behavior, and its evaluation remains problematic.(10) Non-compliance to chronic disease therapy is a problem faced by many health services and is the main obstacle to cure.(11) It may result in disease progression and, when caused by an infectious agent, resistant microorganisms. Long-term treatment of PCM can lead to a non-compliance.(5,12-14)

The purpose of this study was to assess the factors associated with treatment compliance for patients with PCM, aiming to design interventions to improve the care and quality of life for these patients.

METHODS

This study was conducted at the Hospital Dia Professora Esterina Corsini at the Universidade Federal de Mato Grosso do Sul, which is a reference center for PCM. All patients with active PCM admitted between January 2000 and December 2010 were invited to participate in the present investigation. Only confirmed cases, characterized by the presence of clinical manifestations compatible with PCM and the identification of typical Paracoccidioides spp. yeast forms using direct mycological or histopathological examination, were included in this study. Patients who died at the beginning of their treatment were excluded. This study used data collected prospectively by a standardized form with demographic, epidemiological, and clinical data. The same physician supervised the patients throughout the study period.

The antifungal compounds used for initial treatment were selected considering severity of disease, possibility of gastrointestinal absorption of the drug, and the presence of associated diseases. For some cases of severe forms, the dose of conventional amphotericin B 0.5 to 0.7 mg/kg/day was indicated. Intravenous trimethoprim-sulfamethoxazole combination (cotrimoxazole) was prescribed at a dose of 800mg/160mg every 8 hours for at initial treatment of some severe cases. For most of the cases, cotrimoxazole was administered at a dose of 1,200 mg/240 mg every 12 hours or itraconazole 200mg once at day was indicated. For complementary treatment, cotrimoxazole was prescribed at a dose of 800mg/160mg every 12hours, while itraconazole was prescribed at the same dose as during initial treatment.

The follow-up regimen included re-evaluation after 1 month of treatment, then every 2 months thereafter until clinical cure was reached. Clinical cure was defined as the disappearance of the previously observed symptoms and normalization of the erythrocyte sedimentation rate. Patients were then evaluated every 2 to 3 months until serological cure by immunodiffusion.(7) Treatment with itraconazole was maintained for at least 1 year, whereas the cotrimoxazole was continued for at least 2 years. After this period, the drug was suspended if the patient had reached and maintained serological cure for 6 months. Patients whose initial serology was unreactive or not performed used the time for treatment above described. All the antifungal compounds were provided to the patients at no cost.

Treatment compliance was defined by the presence of two conditions: (1) appointment compliance of, at least 80% of appointments during the follow-up period; and (2) medication compliance, having pharmacy confirmed drug dispensing and the patient reported the administration of at least 80% of the antifungal doses prescribed since their previous appointment.

Cigarette smoking, alcoholism and tuberculosis were included in the analysis as co-morbidities. We defined smokers as those who reported smoking one or more cigarettes per day, while alcohol users were those who reported regularly drinking alcohol, and tuberculosis was defined by the identification of acid-fast bacilli in histopathological examination, sputum smears, or culture of clinical specimens.

Statistical analysis was performed using Epi InfoT 7 (Centers for Disease Control and Prevention, Atlanta, GA, USA). Categorical variables were expressed as percentages and were compared using the Chi-squared test, or the Fisher's exact test. The Cochran Q test was used to compare percentages in dependent populations. Odds ratios (OR) and 95% confidence intervals (95%CI) were used to assess the association of the variables with compliance. Confounding effects were minimized by performing binary logistic regression adjusting for potential confounders identified in the analysis. These potential confounders are variables that were found to have p ≤ 0.20. The level of significance used in the analysis was 0.05.

This study was approved by the Ethics Committee of the Universidade Federal de Mato Grosso do Sul (CAE 05200812.0.0000.0021).

RESULTS

A total of 188 patients were initially enrolled in the study, with a mean of 17 cases per year. As 4 patients (2.1%) died at the beginning of the initial therapy and were excluded from the study, 184 cases were analyzed (Figure 1). The patients' ages ranged from 4 to 94 years (median: 48 years). The male-to-female ratio was 22.5:1.0. In all, 82.4% of patients were rural workers, 93.1% were cigarette smokers, and 81.9% had alcoholism. The median time between onset of symptoms and diagnosis was 5 months, ranging from 1 to 120 months. Sequelae characterized by fibrotic scars occurred in 77 (41%) patients, with predominance in the lungs, where it was detected in 66 (35.8%) patients, by thorax radiography or computed tomography (CT scan). Other sites with fibrotic scars were observed in adrenal glands (8 patients; 4.3%) by CT scan; in the larynx (6 patients; 3.3%) by laryngoscopy, in the mouth (4 patients; 2.2%) and skin (3 patients; 1.6%) through physical examination.




Eighty-six patients completed the treatment, 45 (52.3%) of them had serological cure; at admission, 21 (24.4%) patients showed no reagent serology at admission, and in 20 (23.2%) the serological evaluation was not carried out.

This study shows that only 82 (44.6%) patients were treatment compliant. The main loss to follow-up was observed in the first 4 months of treatment, which was showed by the decrease in the prevalence of the appointments. This prevalence was stable until the 12th month of follow-up, when a new decrease could be observed (Figure 2).




Demographic and epidemiological characteristics were not associated with treatment compliance; however pulmonary paracoccidioidal involvement and PCM tuberculosis co-infection were associated with higher treatment compliance, 2.99 and 2.76 times more, respectively (Tables 1 and 2).







DISCUSSION

The profile of patients with PCM included in this study was in line with the characteristics most frequently reported in the literature − middle-aged males, whose professional activity was associated with intense contact with soil, as well as increased prevalence of the chronic form of the disease.(12-14) Poor treatment compliance was also observed in our study. In developing countries, treatment compliance for chronic conditions often reaches only 20%, leading to negative health statistics and very high costs to society, government, and families of patients.(11)

In contrast, a Brazilian study carried out in 2008 reported a global attendance of scheduled follow-ups, and treatment compliance of 88.2%.(10) In that study, the average individual clinic attendance compliance (ICAC) of 132 patients, with at least 10 routine appointments was 90.3%, with 85.6% of patients attending at least 80% of these clinical evaluations. Mean (± standard deviation) ICAC did not vary with clinical presentation: 90.8 ± 11.9% for patients with the chronic form of the disease and 88.2 ± 9.9% for those with the acute/subacute form (p > 0.05). It should be noted that this service has different characteristics from the other care centers in the country, with a greater emphasis on patient follow-up.

In this same study, the antifungal compliance (appropriate sulfonamide serum levels) of 95 patients treated with trimethoprim-sulfamethoxazole combination therapy was 42.1%, showing that patient self-reporting, in order to assess medication-taking, tends to overestimate compliance.(10) Blood level monitoring of sulfonamides in PCM(15) and of itraconazole(16) in systemic mycosis have been described, however they has not been used to assess compliance in the routine clinical setting, in contrast to other diseases, such as epilepsy. We believe that assessing antifungal therapeutic levels is a feasible strategy, and could be useful in controlling PCM treatment.

In our study, the highest loss to follow-up rate occurred in the first 4 months of treatment. Compliance to prolonged treatments for chronic infectious diseases is a clinical challenge. Patients with tuberculosis also present high rates of discontinuation of treatment, despite presenting different demographic and epidemiological profile of patients with PCM. A study on tuberculosis showed a similar time frame for the discontinuation of the treatment, the median time of which was 4.0 (range 0.5 to 28.9) months.(17) A low perception of disease severity may be a risk factor for treatment abandonment.(18) In patients with PCM, clinical improvement or clinical cure (characterized respectively by a decrease or disappearance of the symptomatology, such as dyspnea and skin/mucous membrane lesions) gives the patient the impression of being "cured".(7) This time period is critical, during which treatment compliance should be the focus; this should be emphasized during the follow-up appointments.

In our study, demographic and epidemiologic variables, such as sex, age range, residence, and rural work activities, were not associated with compliance to a therapeutic regimen, which is in line with previous reports.(10) The geographic location of the patients, i.e. metropolitan or rural areas, may have an effect on accessibility to medical care; however, it did not affect treatment compliance in our study. The World Health Organization considers illiteracy, poor economic conditions, and unemployment to be determinants of poor compliance to treatment of chronic comorbidities. (10,11) However, in our study, no association between education level and treatment compliance was observed.

Our study also showed no association between alcohol consumption and treatment compliance. Using a different approach, another study showed that alcohol intake over 50 mg/day had no impact on age at the onset of illness.(6) However, in our clinical practice, wives and children of patients have reported treatment withdrawal due to alcohol abuse, which is directly related to disease development.(6) This apparent contradiction may be due to the use of a dichotomous variable for frequent alcohol intake in this study, rather than a measurement of its amount.


An analysis of the association between compliance and the organs or systems affected by PCM revealed that pulmonary involvement, identified by radiography or CT scan, is a positive factor for compliance. These pulmonary symptoms are speculated to motivate the patients to attend follow-up appointments. Moreover, the respiratory symptoms can cause greater limitation in daily life, leading patients to be more concerned about their treatment.(19)

Compliance to therapeutic follow-up was also higher for patients with PCM-tuberculosis co-infection. The highest rate of follow-up loss occurred in the first 4 months, when patients with PCM and tuberculosis comorbidity were still on tuberculosis treatment. This finding may be related to the efforts enacted by the National Tuberculosis Control Program in Brazil, with community health workers involved in a directly observed treatment strategy.(20) Additionally, many campaigns have emphasized the importance of never abandoning tuberculosis treatment, which could have influenced the patients' behavior in not abandoning their PCM treatment as well.

The use of itraconazole could be associated with higher compliance rates due to its easier treatment regimen (2 pills/day for itraconazole and 4 to 6 pills/day for cotrimoxazole) and shorter treatment duration. (21) However, our study showed no difference between medications, possibly due to the small number of patients who used itraconazole. As it was reported in the Brazilian literature, the most commonly used antifungal compound to treat PCM is cotrimoxazole. (14,22) Cotrimoxazole is still the most used drug to treat PCM in Brazil because it is given free of charge to the patients through the public health system.

Treatment is considered completed after at least 12 months, if itraconazole was used, or 24 months if cotrimoxazole was used, and until the patient reaches and sustains serological cure for 6 months.(23) Therefore, immunodiffusion is very useful in the follow-up of patients, and when they do not present a significant decrease in the serological titres, it is suspected that they are not complaining to the treatment. In many patients, the serological cure criteria could not be used because serological examination was not performed or was negative at admission. About one-fifth of the patients had negative serology at admission, and this could be explained by the use of antigen obtained from P. brasiliensis strain B339 for serological test in our service.

The lack of standardization in antigen production for PCM serology makes the control of cure difficult in some services. The recent molecular identification of several species of fungi of the genus Paracoccidioides revealed different antigenic compositions among the species. (24) As the serological reactions are specific, patients with PCM caused by P. lutzii produce antibodies that are rarely detected by reactions in which the antigen used was isolated from P. brasiliensis species. As the highest concentration of P. lutzii was described in the Center-West Region of Brazil, it is possible that our serological negative cases at admission were caused by P. lutzii. Recently, a P. lutzii antigen has been identified and isolated,(25) which is not yet available for the vast majority of the clinical services. The same work of antigen identification and antigen validation for double immunodiffusion reactions should be done for all new recognized species.

It should be noted that research is being done to identify biomarkers in the serum of patients with PCM that can confirm this disease in its different stages − active untreated disease, active disease under treatment, clinical cure and serological cure, and when it is the case, PCM relapse.(26)

Some limitations of this study are the absence of objective parameters to evaluate compliance, such as follow-up of the serum levels of the antifungal compounds. More than a century after the first report by Adolfo Lutz,(27) PCM continues to be a relevant public health issue, especially regarding its treatment.

Our results showed the importance of the treatment compliance evaluation in patients with PCM, whose clinical cure is reached much before the immunological recovery. Thus, treatment compliance should be routinely performed in every appointment, including with the support of the social service, to call the patients who did not came to the appointment.
