Résumé

Introdução: O diagnóstico da hanseníase possui números significativos que causam preocupação à saúde pública. Os casos de resistência medicamentosa nessa doença se iniciaram em meados dos anos 60 e diante do problema, a Organização Mundial da Saúde instituiu em 1981 a poliquimioterapia, associação dos antibióticos rifampicina, dapsona e clofazimina, tratamento atual de escolha. A resistência aos fármacos na hanseníase é reportada pela literatura, desvelando um obstáculo à sua eliminação. Apresentamos nessa revisão os principais aspectos da resistência medicamentosa no tratamento para hanseníase e seus impactos. Metodologia: Revisão sistemática sobre os aspectos da resistência medicamentosa utilizando a pesquisa exploratória como metodologia de abordagem. Foram pesquisados os termos resistência medicamentosa, hanseníase, recidiva, alterações genéticas e os operadores booleanos "and" e "or" na busca. Resultados e discussão: A dificuldade de tomar a medicação corretamente foi um dos principais fatores que acarretaram resistência do bacilo Mycobacterium leprae aos fármacos. Homens de países norte e sul-americanos e asiáticos foram os mais atingidos por episódios de resistência. A resistência medicamentosa é uma das principais causas de recidivas em hanseníase. O principal fármaco causador de resistência medicamentosa descrito nos trabalhos foi a dapsona (46,6%) e a maioria das alterações genéticas encontradas estão no gene rpoB; 23,2% dos registros relatados foram de resistência secundária aos fármacos e, também, sete casos de resistência múltipla a esses medicamentos. Conclusão: Os principais aspectos da resistência medicamentosa na hanseníase são os equívocos ao ingerir os medicamentos e as alterações genéticas na bactéria. Os impactos causados estão na dificuldade de refazer o tratamento, a possibilidade de nova transmissão e o aparecimento de sintomas mais graves.


Introduction: The diagnosis of leprosy has significant numbers causing public health concern. Reports of drug resistance in this disease begun in the mid-1960s and due to this problem, the World Health Organization instituted a multidrug therapy with rifampicin, dapsone, and clofazimine antibiotic association in 1981, which is currently the first-choice treatment for leprosy. Cases of drug resistance have been reported in literature, revealing an obstacle to the eradication of the disease. This paper has the purpose of presenting the key aspects and impacts of drug resistance in the treatment for leprosy. Methods: Systematic review of the drug resistance aspects using exploratory research as an approach methodology. The authors searched the terms drug resistance, leprosy, recurrence, genetic alterations, and the Boolean operators "and" and "or" between them. Results and discussion: The difficulty in taking the medication correctly was one of the key factors that led to drug resistance for Mycobacterium leprae. Men from North and South American, as well as from Asian countries, were the most affected by episodes of resistance. Drug resistance is one of the main causes of leprosy recurrences. Dapsone was the most frequently identified drug resistance in the studies (46.6%), while most of the genetic alterations were found in the rpoB gene; 23.2% of the cases were from secondary resistance episodes, and seven cases of multiple resistance were reported. Conclusion: The misconceptions when taking the treatment and the Mycobacterium leprae genetic alterations have been described as the key aspects of drugs resistance in leprosy and the impacts caused are the difficulty in redoing the treatment, the possibility of new transmission, and the appearance of more severe symptoms.

Résumé

Abstract Leprosy is one of the neglected diseases in the world and Brazil is the second country with more cases. A retrospective study was conducted based on the medical records of 196 leprosy patients diagnosed during the course of 13 years at a university hospital. The aim was to describe the adverse effects of polychemotherapy, as well the most prevalent and most vulnerable populations. In the study, dapsone was the most implicated drug, especially in women, and the risk increased with age. The authors conclude that with this patient profile, greater vigilance should be taken regarding possible adverse effects, especially anemia.

Résumé

ABSTRACT Given the global burden of tuberculosis, shortened treatment regimens with existing or repurposed drugs are needed to contribute to tuberculosis control. The long duration of treatment of drug-susceptible tuberculosis (DS-TB) is associated with nonadherence and loss to follow up, and the treatment success rate of multidrug-resistant tuberculosis (MDR-TB) is low (approximately 50%) with longer regimens. In this review article, we report recent advances and ongoing clinical trials aimed at shortening regimens for DS-TB and MDR-TB. We discuss the role of high-dose rifampin, as well as that of clofazimine and linezolid in regimens for DS-TB. There are at least 5 ongoing clinical trials and 17 observational studies and clinical trials evaluating shorter regimens for DS-TB and MDR-TB, respectively. We also report the results of observational studies and clinical trials evaluating a standardized nine-month moxifloxacin-based regimen for MDR-TB. Further studies, especially randomized clinical trials, are needed to evaluate regimens including newer drugs, drugs proven to be or highly likely to be efficacious, and all-oral drugs in an effort to eliminate the need for injectable drugs.


RESUMO Em virtude da carga global da tuberculose, esquemas mais curtos de tratamento com medicamentos já existentes ou reaproveitados são necessários para contribuir para o controle da doença. A longa duração do tratamento da tuberculose sensível (TBS) está relacionada com não adesão e perda de seguimento, e a taxa de sucesso do tratamento da tuberculose multirresistente (TBMR) é baixa (de aproximadamente 50%) com esquemas mais longos. Neste artigo de revisão, relatamos avanços recentes e ensaios clínicos em andamento cujo objetivo é encurtar os esquemas de tratamento de TBS e TBMR. Discutimos o papel da rifampicina em altas doses, assim como o da clofazimina e linezolida em esquemas de tratamento de TBS. Relatamos também os resultados de estudos observacionais e ensaios clínicos de avaliação de um esquema padronizado de nove meses à base de moxifloxacina para o tratamento de TBMR. Mais estudos, especialmente ensaios clínicos randomizados, são necessários para avaliar esquemas que incluam medicamentos mais novos, medicamentos comprovadamente ou provavelmente eficazes e medicamentos exclusivamente orais na tentativa de dispensar o uso de medicamentos injetáveis.

Résumé

ABSTRACT Rapidly progressive glomerulonephritis (RPGN) is a renal disease with an extensive differential diagnosis. This paper reports the case of a 55-year-old female patient diagnosed with Hansen's disease with acute progressive renal impairment after developing lower limb pyoderma. The association between Hansen's and kidney disease has been well documented, with glomerulonephritis (GN) ranked as the most common form of renal involvement. Post-infectious glomerulonephritis (PIGN) in adults has been associated with a number of pathogens occurring in diverse sites. The patient described in this case report had RPGN and biopsy findings suggestive of PIGN with C3 and IgA detected on immunofluorescence and kidney injury secondary to recent infection by Staphylococcus, a well-documented manifestation of renal impairment in patients with Hansen's disease.


RESUMO A Glomerulonefrite Rapidamente Progressiva (GNRP) é um padrão de doença renal com amplo diagnóstico diferencial. O caso reporta uma paciente de 55 anos com deterioração aguda e progressiva da função renal após quadro de piodermite em membro inferior com diagnóstico concomitante de hanseníase. Associação da hanseníase com doença renal é bem descrita, sendo a GN a forma de acometimento renal mais comum. As glomerulonefrites pós-infecciosas (GNPIs) em adultos ocorrem devido a um grande número de patógenos, nos mais diversos sítios. A paciente do caso relatado apresentava quadro de GNRP e achados de biópsia que sugerem GNPI com marcação de C3 e IgA na imunofluorescência, sugestiva de lesão renal secundária a infecção recente por Staphylococcus, uma manifestação bem descrita de doença renal em pacientes com hanseníase.

Résumé

The pathogen Mycobacterium avium complex (MAC) is the most common cause of nontuberculous mycobacterial pulmonary disease worldwide. The decision to initiate long-term antibiotic treatment is difficult for the physician due to inconsistent disease progression and adverse effects associated with the antibiotic treatment. The prognostic factors for the progression of MAC pulmonary disease are low body mass index, poor nutritional status, presence of cavitary lesion(s), extensive disease, and a positive acid-fast bacilli smear. A regimen consisting of macrolides (clarithromycin or azithromycin) with rifampin and ethambutol has been recommended; this regimen significantly improves the treatment of MAC pulmonary disease and should be maintained for at least 12 months after negative sputum culture conversion. However, the rates of default and disease recurrence after treatment completion are still high. Moreover, treatment failure or macrolide resistance can occur, although in some refractory cases, surgical lung resection can improve treatment outcomes. However, surgical resection should be carefully performed in a well-equipped center and be based on a rigorous risk-benefit analysis in a multidisciplinary setting. New therapies, including clofazimine, inhaled amikacin, and bedaquiline, have shown promising results for the treatment of MAC pulmonary disease, especially in patients with treatment failure or macrolide-resistant MAC pulmonary disease. However, further evidence of the efficacy and safety of these new treatment regimens is needed. Also, a new consensus is needed for treatment outcome definitions as widespread use of these definitions could increase the quality of evidence for the treatment of MAC pulmonary disease.

Résumé

Mycobacterium abscessus is the second most important pathogen in pulmonary disease caused by nontuberculous mycobacteria (NTM), following Mycobacterium avium. Mycobacterium abscessus is classified into three subspecies: M. abscessus subsp. abscessus, M. abscessus subsp. massiliense, and M. abscessus subsp. bolletii. Mycobacterium abscessus is the most difficult to treat NTM due to its resistance to many antibiotics. Treatment should include an initial regimen of 2–3 injectable and oral antibiotics for several weeks or months, followed by inhaled amikacin and 1–3 oral antibiotics, depending on the subspecies and drug susceptibility patterns, including macrolide susceptibility. The continuation phase should be continued for a minimum of 12 months after culture conversion. Suitable injectable antibiotics include amikacin, imipenem, cefoxitin, and tigecycline, while oral antibiotics include macrolides (azithromycin or clarithromycin), clofazimine, linezolid, and moxifloxacin. Surgery can be a useful adjunctive therapy for some patients with refractory disease. However, the overall treatment prognosis is still unsatisfactory. Therefore, novel and more effective interventions are required for the treatment of M. abscessus pulmonary disease.

Résumé

Abstract: BACKGROUND: The Clinical Trial for Uniform Multidrug Therapy for Leprosy Patients in Brazil (U-MDT/CT-BR), designed to evaluate the effectiveness of a six-months regimen, assessed the adverse effects caused by the drugs. OBJECTIVE: Describe adverse effects due to MDT in U-MDT/CT-BR, comparing the uniform regimen (U-MDT) to the current WHO regimen (R-MDT). Patients and methods: After operational classification, patients were randomly allocated to the study groups. U-MDT PB and U-MDT MB groups, received the U-MDT regimen, six doses of MB-MDT (rifampicin, dapsone and clofazimine). R-MDT PB and R-MDT MB groups, received the WHO regimens: six doses (rifampicin and dapsone) for PB and 12 doses (rifampicin, dapsone and clofazimine) for MB. During treatment, patients returned monthly for clinical and laboratorial evaluation. Patients with single lesion were not included in this trial. RESULTS: Skin pigmentation (21.7%) and xerosis (16.9%) were the most frequent complaints among 753 patients. Laboratory exams showed hemoglobin concentration lower than 10g/dL in 23.3% of the patients, glutamic oxaloacetic transaminase (GOT) above 40U/L in 29.5% and glutamic pyruvic transaminase (GPT) above 40U/L in 28.5%. Twenty-four patients (3.2%) stopped dapsone intake due to adverse effects, of whom 16.6% due to severe anemia. One case of sulfone syndrome was reported. STUDY LIMITATIONS: Loss of some monthly laboratory sample collection. CONCLUSIONS: There was no statistical difference regarding adverse effects in the R-MDT and U-MDT groups but anemia was greater in patients from R-MDT/MB group, therefore adverse effects do not represent a constraint to recommend the six-month uniform regimen of treatment for all leprosy patients.

Résumé

Abstract: Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up.

Résumé

La lepra es una infección crónica, granulomatosa, producida por Mycobacterium leprae, que afecta piel y nervios periféricos. Se describen dos tipos de reacciones leprosas: tipo I y tipo II, las que corresponden a cuadros agudos que exacerban la enfermedad. Estas leproreacciones pueden ocurrir antes, durante o después del tratamiento. Se presenta el caso de un paciente masculino que acude a consultar con lesiones cutáneas y resultado de biopsia de piel con diagnóstico de lepra. Se inicia tratamiento multidroga OMS-MB1. Posteriormente presenta una leproreacción tipo I, por lo que se le realiza tratamiento con prednisona.


Leprosy is a chronic granulomatous infection of the skin and peripheral nervous system produced by Mycobacterium leprae. Two types of acute leprosy reactions have been described: type I and type II. These reactions can occur before, during or after treatment. We present the case of an adult male patient presenting with skin lesions and skin biopsy diagnostic for leprosy. A multidrug WHO-MB 1 treatment was initiated, after which he presents with type I lepra reaction requiring corticosteroids.

Résumé

Abstract: Ashy dermatosis is a rare condition, of unknown aetiology, in which mucous membranes are typically spared. The authors report the case of a 57-year-old female with a history of asymptomatic gray-bluish macules located on the trunk and oral mucosa. There were no relief changes on examination. Skin biopsies from the oral mucosa and trunk were performed and both were compatible with ashy dermatosis. The patient started treatment with oral clofazimine but due to the absence of clinical improvement the drug was discontinued three months later. This case report illustrates an atypical case of ashy dermatosis owing to the involvement of mucous membranes, which is rarely described in the literature.

Résumé

Resumen El tratamiento de las tuberculosis multidrogorresistentes (TBC-MDR) se basa en esquemas de fármacos con diseños muy variables, en pacientes con patrones de resistencia heterogéneos y seguimientos no estandarizados, lo que hace dificil plantear recomendaciones con fuerte nivel de evidencia. Además, sólo una minoría de estos enfermos recibe tratamiento a nivel mundial y con los actuales esquemas menos del 50% de los que logran ser tratados curan. Afortunadamente, durante los últimos años han aparecido nuevos medicamentos, (bedaquilina, delamanid y pretomanid), que están demostrando ser de real utilidad para estos pacientes en ensayos con mejor diseño y seguimiento, donde se puede establecer con mayor precisión la eficacia, toxicidad y grado de recaídas. Además, algunos fármacos ya conocidos, (fluoroquinolonas, linezolid, clofazimina) están siendo introducidos dentro de los nuevos esquemas de tratamiento.


Abstract Therapy of multi-drug resistant tuberculosis (MDR TB) is based on trials with drugs with highly variable patterns of resistance and non-standardized follow-ups that make it difficult to provide recommendations with strong levels of evidence. Also, the vast majority of MDR-TB patients fail to receive therapy and those who receive it, only achieve around 50% of good results. Fortunately new drugs have emerged (bedaquiline, delamanid, pretomanid) that are being useful for these patients with better designed trials and monitoring, in which the efficacy, toxicity and degree of relapses can be evaluated more accurately. Some drugs already known (fluorquinolones, linezolid and clofazimine) are also being introduced in new schemes of therapy.

Résumé

La dermatosis cenicienta es una hipermelanosis idiopática con máculas de color azul grisáceo, que fue descrita inicialmente en El Salvador por Oswaldo Ramírez en 1957. Predomina en la población hispana de piel fototipo IV, siendo más común en adultos entre la segunda y tercera década de la vida. Aunque se desconoce la etiología, se han identificado factores predisponentes como la ingesta de nitrato de amonio, benzodiacepinas, exposición a pesticidas y fungicidas como clorotalonil, entre otros. A nivel histopatológico se visualiza degeneración e hiperpigmentación de la capa basal. Clínicamente, el tórax y las extremidades proximales son las áreas anatómicas comúnmente afectadas en esta enfermedad asintomática y de curso crónico. La historia clínica y el examen físico son la base del diagnóstico, así como una biopsia de piel de los bordes activos para confirmar el mismo. Aunque existen diversas opciones terapéuticas, solamente la clofazimina y la dapsona han mostrado eficacia en el tratamiento de la dermatosis cenicienta. El líquen plano pigmentado y la pigmentación macular eruptiva idiopática son dos de los principales diagnósticos diferenciales que el clínico debe considerar.


Ashy dermatoses is an idiopathic hypermelanosis with blue-gray macules, which was first described by Oswaldo Ramírez in El Salvador in 1957. It predominates in the Hispanic population with skin type IV, being most common in adults between the second and third decade of life. Although the etiology is unknown, predisposing factors have been identified as the intake of ammonium nitrate, benzodiazepines, exposure to pesticides and fungicides such as chlorothalonil, etc. Degeneration and hyperpigmentation of the basal layer is the main histopathologycal characteristics. Clinically, the chest and the proximal extremities are the anatomical areas commonly affected in this asymptomatic disease with chronic course. The clinical history and the physical examination are the basis of diagnosis, the biopsy of the skin active borders confirms it. Although there are several treatment options, only dapsone and clofazimine have shown efficacy in the ashy dermatosis treatment. Lichen planus pigmentosus and idiopathic eruptive macular pigmentation are two of the main differential diagnoses, the clinician should consider.

Résumé

PURPOSE: To report a case of secondary pigmentary glaucoma due to clofazimine treatment for extensive drug-resistant tuberculosis. CASE SUMMARY: A 23-year-old man presented with blurred vision in both eyes. The patient started to take clofazimine for extensive drug-resistant tuberculosis six months prior, after which his facial skin color changed to a dark-brown. Intraocular pressure (IOP) was 50 mm Hg in the right eye and 48 mm Hg in the left eye. Slit lamp examination revealed corneal edema, opacity, and flare in the anterior chamber in both eyes. A color vision test revealed a mild color defect in both eyes. Visual field (VF) test revealed superior temporal VF loss in the left eye. Gonioscopy revealed open angles with high pigmentation in the trabecular meshwork in both eyes. The patient was diagnosed with pigmentary glaucoma, and maximum tolerated medical therapy was performed. However, the IOP was uncontrolled. Trabeculectomy was performed in both eyes. Postoperative IOP was measured to be 12 mm Hg in both eyes without medication, and visual acuity measured 20/22 in the right eye and 20/17 in the left eye. CONCLUSIONS: To the best of our knowledge, this report is the first case of clofazimine being a possible cause of pigmentary glaucoma in a patient with extensive drug-resistant tuberculosis.

Résumé

Despite global efforts to control tuberculosis (TB), multidrug-resistant TB (MDR-TB) is still a serious problem worldwide. The diagnosis of MDR-TB is based on mycobacterial culture followed by drug susceptibility testing, with results available in weeks to months. This requirement calls for rapid direct tests, especially genotypic tests, in which specimens are amplified directly for the detection of MDR-TB. The treatment of MDR-TB is challenging because of the high toxicity of second-line drugs and the longer treatment duration required compared to drug-susceptible TB. The selection of drugs in MDR-TB is based on the treatment history, drug susceptibility results, and TB drug resistance patterns in each region. Recent World Health Organization guidelines recommend the use of at least four second-line drugs (i.e., a newer fluoroquinolone, an injectable agent, prothionamide, and cycloserine or para-aminosalicylic acid) in addition to pyrazinamide. Kanamycin is the initial choice of an injectable drug, and newer fluoroquinolones include levofloxacin and moxifloxacin. For extensively drug-resistant TB, group 5 drugs such as linezolid and clofazimine need to be included. New drugs such as delamanid and bedaquiline have recently been approved for treating MDR-TB and other agents with novel mechanisms of action that can be given for shorter durations (6-12 months) for MDR-TB are under investigation.

Résumé

A hanseníase é uma doença infecciosa crônica que se caracteriza por um espectro de manifestações clínicas dermatoneurológicas associadas com diferentes padrões de resposta imune. [...] O estudo realizado foi retrospectivo, de coorte, a partir do levantamento de dados dos pacientes diagnosticados com hanseníase no Ambulatório Souza Araújo /Fiocruz,Rio de Janeiro, que receberam tratamento padrão com poliquimioterapia entre os anos de 1997 e 2007.O presente estudo analisou as características epidemiológicas, clínicas e laboratoriais do grupo em abandono do tratamento com a poliquimioterapia (PQT) e as características do grupo alta por cura. A proporção de abandono foi baixa, provavelmente em razão do local do estudo ser um centro de referência para tratamento e pesquisa. Houve um predomínio do sexo masculino nos dois grupos,a idade média em ambos os grupos foi em torno de 40 anos que corresponde a faixa etária economicamente ativa da população, o nível de escolaridade no grupo em abandono e dos que obtiveram alta por cura foi baixo, ocorreu predomínio de paucibacilares nos dois grupos, porém a maioria apresentou Mitsuda negativo.O grau de incapacidade zero e o índice baciloscópico zero predominaram nos dois grupos...

[...] This study is a retrospective cohort study based ona survey of data from patients diagnosed with leprosy at the Ambulatório Souza Araújo / FIOCRUZ , Rio deJaneiro , who received standard treatment with multidrug therapy between 1997 and 2007.The present workexamines the epidemiological, clinical and laboratory characteristics of the group in abandonment of treatmentwith multidrug therapy ( MDT ) and the characteristics of the group adherent to treatment. The proportion ofdropout was low, probably because the study site is a referral center for treatment and research. There was apredominance of males in both groups, the mean age in both groups was around 40 years which corresponds tothe economically active age group of the population, the level of education in the group was leaving and stickdown, there was a predominance of paucibacillary in both groups, but the majority showed Mitsuda negativo.Zero degree of disability and the bacterial index zero predominated in both groups. A higher proportion of casesof abandonment in the first months of treatment. Study evaluated the relationship between noncompliance MDTand the occurrence of leprosy reactions , as well as epidemiological, clinical and laboratory characteristics of thedifferent groups of treatment with MDT...

Résumé

Relatamos a ocorrência da Síndrome Inflamatória da RecuperaçãoImune (IRIS), após reversão de agranulocitose, induzida por poliquimioterapia,em paciente do sexo feminino acometida por hanseníasedimorfa-virchowiana. Propomos que em todos os pacientes submetidosà poliquimioterapia para hanseníase sejam efetuados periodicamenteexames laboratoriais que possam identificar precocementedistúrbios hematológicos graves


We report the occurrence of Immune Reconstitution InflammatorySyndrome (IRIS) after reversal of agranulocytosis provoked by drugor drugs used in the treatment of leprosy. After suspension of thedrugs under suspicion and the recovery of the hematologic disturbanceand as consequence the restoration of the immune conditionwe started an alternate treatment for Hansen’s disease. Takingthis case as an example, we propose that all patients with leprosyand under treatment with drugs such as dapsone and/ or rifampicinshould have a periodical hemogram to identify premature hematologicanomalies.

Résumé

BACKGROUND: After the introduction of the multidrug therapy, there was a decline in the coefficients of prevalence and detection of new cases of leprosy. However, the records of drug resistance and relapses are threatening factors in leprosy control. Hence, new alternative schemes and monitoring of adverse effects to avoid treatment abandonment are important considerations. OBJECTIVE: Describe the side effects of a multidrug regimen containing minocycline, ofloxacin, and clofazimine in multibacillary leprosy patients. METHODS: We conducted a prospective, descriptive, and observational study with multibacillary patients, including cases of intolerance to standard MDT and relapses. The study was carried out at Fundação Alfredo da Matta (Alfredo da Matta Foundation), in Manaus, Amazonas, from April 2010 to January 2012. The patients received alternative therapy, which consisted of daily self-administered doses of 100mg of minocycline, 400 mg of ofloxacin, and 50mg of clofazimine and a supervised monthly dose of 300mg of clofazimine for six months, followed by eighteen months of daily doses of ofloxacin 400mg, clofazimine 50mg, and a supervised monthly dose of clofazimine 300mg. Results: Twenty-one cases were included. Mild and transitory side effects occurred in 33.3% of patients. Of the total episodes, 45.9% were attributed to ofloxacin and they included abdominal pain, nausea, vomiting, headache, and insomnia; 21.6% were due to clofazimine, with 100% of patients presenting skin pigmentation. The mean time for the development of adverse effects after beginning the therapy was 15.2 days. CONCLUSION: All patients tolerated the drugs well, and compliance was satisfactory, with no serious events. Unlike other standard MDT studies ...


FUNDAMENTOS: Após introdução do esquema poliquimioterápico padrão, houve declínio nos coeficientes de prevalência e detecção de casos novos; entretanto, os registros de resistência medicamentosa e recidivas representam ameaça para o controle da hanseníase. Dessa forma, a proposição de novos esquemas alternativos e a necessidade de monitorar efeitos adversos são importantes para evitar o abandono do tratamento. OBJETIVO: Descrever efeitos adversos do esquema alternativo contendo clofazimina, ofloxacina e minociclina em pacientes com hanseníase multibacilar. MÉTODOS: Estudo prospectivo, descritivo e observacional de casos multibacilares, incluindo recidivas ou intolerância à poliquimioterapia padrão, realizado na Fundação Alfredo da Matta, Manaus, Amazonas, de abril de 2010 a janeiro de 2012. Os indivíduos receberam a terapia composta de doses diárias auto-administradas de 100mg de minociclina, 400mg de ofloxacina e 50mg de clofazimina e mensais supervisionadas de 300mg de clofazimina por seis meses, seguidas de 18 meses de doses diárias de ofloxacina 400mg, clofazimina 50 mg e supervisionadas mensais de clofazimina 300mg. Resultados: 21 pacientes foram incluídos. Efeitos adversos leves e transitórios foram observados em 33,3% dos pacientes; 45,9% foram atribuídos à ofloxacina, como dor abdominal, náuseas, vômitos, cefaléia e insônia; 21,6% foram associados à clofazimina, com relatos e observação em 100% dos pacientes de hiperpigmentação cutânea. O tempo médio de desenvolvimento das reações adversas a partir do início do esquema foi de 15,2 dias. ...
