ABSTRACT

Introduction: The term candiduria refers to the presence of yeast in urine and Candida albicans is the most common agent. In general, routine laboratories do not perform identification and cultivation of yeast. Objectives: To determine the prevalence of Candida species and to evaluate the antifungal susceptibility of the species isolated in urine of outpatients Jataí-GO, between January-October 2013. Material and method: Urine samples containing fungal structures were plated out on Sabouraud agar with chloramphenicol. Differentiation was taken with the urease test, nitrogen and carbon sources assimilation, germ tube test, morphology on cornmeal agar and chromogenic agar cultivation. Susceptibility was evaluated at antifungal itraconazole, fluconazole, amphotericin B and ketoconazole. Results: 1,215 urine tests were performed, and 64 had fungal structures (5.3%). Two samples were lost, thus here we considered 62 isolates. From this total, 43 were identified as C. albicans (67.2 %), eight C. glabrata (12.5 %), five C. krusei (7.8%), three C. tropicalis (4.7%), and three could not determine the species (4.7%). Amphotericin B and ketoconazole inhibited 94.9% of the isolates. On the other hand, 55.9% and 54.2 % were resistant to itraconazole and fluconazole, respectively. The resistance rates of both fluconazole and itraconazole for C. glabrata and C. albicans, as fluconazole for C. albicans and C. krusei, showed significant differences (p < 0.05). Conclusion: These data demonstrate the importance of conducting a full identification and susceptibility to antifungal agents in samples with yeast infection...


Introdução: O termo candidúria designa a presença de leveduras na urina e Candida albicans é o agente mais comum. Em geral, os laboratórios de rotina não realizam o cultivo e a identificação da levedura. Objetivos: Determinar a prevalência de espécies de Candida e avaliar o perfil de sensibilidade aos antifúngicos das espécies isoladas em urina de pacientes ambulatoriais do município de Jataí-GO, entre janeiro e outubro de 2013. Material e método: Amostras de urina que continham estruturas fúngicas foram semeadas em ágar Sabouraud com cloranfenicol. A diferenciação foi feita com provas da urease, assimilação de fontes de nitrogênio e carbono, tubo germinativo, morfologia em ágar fubá e cultivo em ágar cromogênico. Foi avaliada a sensibilidade aos antifúngicos itraconazol, fluconazol, anfotericina B e cetoconazol. Resultados: Foram realizados 1.215 exames de urina, sendo que 64 apresentaram estruturas fúngicas (5,3%). Houve perda de duas amostras, assim, considerou-se 62 isolados. Desse total, 43 foram identificadas como C. albicans (67,2%); oito, C. glabrata (12,5%); cinco, C. krusei (7,8%); três, C. tropicalis (4,7%); e em três não foi possível determinar a espécie (4,7%). Anfotericina B e cetoconazol inibiram 94,9% dos isolados. Por outro lado, 55,9% e 54,2%, respectivamente, apresentaram resistência a itraconazol e fluconazol. As taxas de resistência a itraconazol e fluconazol de C. glabrata e C. albicans e também do fluconazol entre C. albicans e C. krusei apresentaram diferenças significativas (p < 0,05). Conclusão: Os dados demonstram a importância de se realizar a identificação completa e também o antifungigrama para amostras que apresentam infecção por leveduras...

ABSTRACT

Treating sexual partners of women with vaginal candidiasis and bacterial vaginosis is an issue in debate. Despite the present recommendations of the international guidelines to not to treat the asymptomatic sexual partners, this is a frequent practice between gynecologists. Objective: evaluate the influence of treating asymptomatic sexual partner of women with recurrent vulvovaginitis. Methods: databases searched: PubMed, Embase, Scielo and CINAHAL. Selection criteria: randomized clinical trials published from 1982 to 2012 were included. Studies involving pregnant women were excluded. Methodological quality was assessed using the Jadad scale. Data collection and analysis: Review Manager 5.1 was used for statistical analysis. Results: eight randomized clinical trials were included based on the chosen criteria: 1,088 women were enrolled. For bacterial vaginosis, the RR for cure was 1.00 (95%CI: 0.95?1.05) (p = 0.13), and for recurrence 0.84 (95%CI: 0.62-1.14) (p = 0.34). Vaginal candidiasis had a RR of 1.03 (95%CI: 0.94-1.14) (p = 0.48) for cure, and 1.02 (95%CI: 0.77?1.33 p = 0.91) for recurrence. Conclusion: treatment of asymptomatic sexual partners of women with vaginal candidiasis or bacterial vaginosis does not affect the cure or recurrence rates and may increase the risk of side effects and unnecessary financial costs.

ABSTRACT

BACKGROUND: Pityriasis versicolor is a fungal infection caused by Malassezia spp. that has frequent relapses. OBJECTIVES: The main objective of this research was to perform phase I and II clinical studies, using formulations containing essential oil of Cymbopogon citratus in patients with pityriasis versicolor. METHODS: Phase I study included twenty volunteers to ascertain the safety of the formulations. In phase II, 47 volunteers randomly received essential oil formulations at 1.25 μL/mL concentration, for forty days. The shampoo should be applied three times a week and the cream twice a day. A control group in phase II, consisting of 29 volunteers, received the same formulations but with 2% ketoconazole as the active ingredient. RESULTS: No significant adverse events were observed in volunteers during Phase I. In Phase II, 30 (63.83%) volunteers using essential oil and 18 (62.07%) using ketoconazole remained until the end of the study. We observed a predominance of lesions in disseminated form, with M. sympodialis detected as the predominant agent identified in cultures. After 40 days of treatment, the rate of mycological cure was 60% (p <0.05) for the group treated with essential oil of C. citratus and over 80% (p <0.05) for the group treated with ketoconazole formulations. CONCLUSIONS: Notwithstanding the safety and antifungal effects observed in this study after application of formulations containing the essential oil of C. citratus, further studies with larger populations should be performed to confirm the actual potential of these formulations in the treatment of patients with Pityriasis versicolor. .


FUNDAMENTOS: Pitiríase versicolor é uma micose causada pela Malassezia spp., e que apresenta frequentes recidivas. OBJETIVOS: Este trabalho objetivou realizar estudos clínicos de fase I e II, para essa patologia, com óleo essencial de Cymbopogon citratus. MÉTODOS: Na fase I, participaram vinte voluntários para averiguar a segurança das formulações. Na fase II, 47 voluntários receberam as formulações do óleo essencial a 1,25 μL/mL, as quais deveriam ser utilizadas por quarenta dias, sendo o xampu três vezes por semana e o creme duas vezes ao dia. Um grupo controle na fase II, constituído por 29 voluntários recebeu as mesmas formulações, com cetoconazol a 2%. RESULTADOS: Verificada a segurança das formulações com a finalização da fase I, onde nenhuma reação adversa significativa foi observada nos indivíduos sadios, conduziu-se a fase II. Nesta segunda fase, 30 (63,83%) voluntários utilizando óleo essencial e 18 (62,07%) cetoconazol permaneceram até o final do estudo. Observaram-se nos pacientes com pitiríase versicolor predomínio de lesões na forma disseminada e M. sympodialis foi o agente predominante identificado em cultura. Após 40 dias de tratamento, obteve-se um percentual de cura micológica de 60% (p < 0,05) para o grupo tratado com óleo essencial de C. citratus e superior a 80% (p < 0,05) para o grupo tratado com cetoconazol. CONCLUSÕES: Apesar da segurança e efeito antifúngico observados após aplicação das formulações contendo óleo essencial de C. citratus, outros estudos com maior número de portadores de pitiríase versicolor precisam ser realizados para confirmar o real potencial destas f...

ABSTRACT

Glucocorticoid hypersensitivity syndrome has been reported to date only in several patients. This article describes a unique case of this syndrome in a 24-year old female admitted to hospital because of arterial hypertension and obesity. Although her clinical picture suggested Cushing's syndrome, she had low adrenocorticotropic hormone (ACTH) and cortisol levels with a poor response to corticotrophin-releasing hormone and Synacthen. In turn, an overnight dexamethasone suppression test with 0.25 mg of dexamethasone led to a dramatic decrease in morning cortisol. A diagnosis of glucocorticoid hypersensitivity was made and the patient started treatment with ketoconazole and cabergoline, which resulted in some clinical improvement. This case illustrates the need for clinical awareness of glucocorticoid hypersensitivity in patients suspected of Cushing's syndrome.


El síndrome de la hipersensibilidad glucocorticoidea ha sido reportado hasta la fecha en varios pacientes. Este artículo describe un caso único de este síndrome en una mujer de 24 años, ingresada en el hospital debido a hipertensión arterial y obesidad. Aunque su cuadro clínico hizo pensar en el síndrome de Cushing, presentaba un bajo nivel tanto de hormona adrenocorticotropa (ACTH) como de cortisol, acompañado de una respuesta pobre a la hormona liberadora de corticotropina y al synacthen. A su vez, una prueba de supresión de la dexametasona realizada durante la noche con 0.25 mg de dexametasona, condujo a una disminución dramática del cortisol en la mañana. Se hizo un diagnóstico de hipersensibilidad glucocorticoide, y la paciente empezó el tratamiento con ketoconazol y cabergolina, lo cual trajo como consecuencia cierta mejoría clínica. Este caso ilustra la necesidad de una mayor conciencia clínica en torno a la hipersensibilidad glucocorticoidea en pacientes sospechosos de padecer el síndrome de Cushing.

ABSTRACT

La candidiasis orofaríngea (COF) permanece como una de las principales infecciones oportunistas en pacientes infectados con el virus de la inmunodeficiencia humana (VIH) y con el síndrome de inmunodeficiencia adquirida (sida), y aunque su incidencia ha disminuido con la introducción de la terapia antirretroviral de alta eficacia, continúa siendo una afección característica en estos pacientes. En el presente trabajo se realizó un estudio de susceptibilidad in vitro mediante la metodología del CLSI, frente a itraconazol, ketoconazol y clotrimazol de 144 aislamientos clínicos de Candida, aisladas de la cavidad oral de pacientes infectados con el VIH/sida con cuadros clínicos de COF. La identificación de los aislamientos demostró que más del 90% pertenecían a Candida albicans. Al determinar el patrón general de susceptibilidad frente a los azoles estudiados mediante el método de microdilución en caldo del documento M27-A2 del Clinical and Laboratory Standard Institute, C. albicans exhibió valores de concentración mínima inhibitoria (CMI) en un rango de 0,01 a 8µg/mL para el itraconazol y el ketoconazol y de 0,01 a 2 g/mL para el clotrimazol. Sólo el 2,1 % de los aislamientos mostró franca resistencia frente al itraconazol, en tanto que el 3,5 % quedó clasificado dentro de la categoría “susceptible dosis-dependiente” para este triazol. La mayoría de los aislamientos de C. albicans mostraron valores de CMI frente al ketoconazol y al clotrimazol menores a 0.06 g/mL, siendo de un 96,9% (129 aislamientos) y de un 97,7% (129 aislamientos), respectivamente. El clotrimazol tuvo una mejor actividadin vitro comparado con los restantes azoles frente a los aislamientos estudiados. Candida spp. Mostró una elevada sensibilidad in vitro a los azoles estudiados. Se hace necesario continuar realizando estudios epidemiológicos para determinar los patrones de susceptibilidad y tasas de resistencias frente a los agentes...


The oropharyngeal candidiasis (OFC) remains as one of the principal opportunistic infections in patients infected with the human immunodeficiency virus (HIV) and with the acquired immunodeficiency syndrome (aids), and although his incidence has declined with the introduction of the highly active anti-retroviral therapy (HAART), remains as a typical complaint in these patients. A study of antifungal in vitro susceptibility testing, following the CLSI methodology, was realized against itraconazole, ketoconazole and clotrimazole of 144 clinical isolations of Candida, isolated from the oral cavity of patients infected with HIV/aids, with clinical pictures of OFC. The isolation’s identification, demonstrated that more than 90% belonged to Candida albicans. The determination of the general pattern of susceptibility, following the document M27-A2 of the Clinical and Laboratory Standard Institute, against to the studied azoles by means of the method of microdilution in liquid medium, show that the majority of C. albicans isolates showed values of MIC against ketoconazole and clotrimazole lower than 0.06 g/mL, representing a 96,9% (129 isolations) and a 97,7% (129 isolations), respectively. C. albicans exhibited the widest range of minimal inhibitory concentration (MIC). Only 2.1% of the isolations showed resistance against to itraconazole, while 3.5 % remained classified in the category “sensible dose - dependent” for this triazole. The majority of the strains showed values of MIC against ketoconazole and clotrimazole below 0.06 g/mL. The clotrimazole had a better in vitro activity compared with the remaining azoles opposite to the isolations. Candida spp. showed a high in vitro sensibility to the azoles studied. It becomes necessary the maintenance of epidemiologic studies for the determination of susceptibility patterns and of resistances rates against to the antifungal agents

ABSTRACT

FUNDAMENTO: A pitiríase versicolor é uma doença infecciosa causada por várias espécies de Malassezia com uma tendência a se tornar recidivante ou crônica. OBJETIVOS: Este trabalho foi conduzido na tentativa de conhecer a evolução clínica da pitiríase versicolor em relação ao número de recidivas após um tratamento adequado no período de 12 meses e correlacionar o número de recidivas com as espécies de Malassezia isoladas. MATERIAL E MÉTODOS: Cento e dois pacientes com diagnóstico clínico e laboratorial de pitiríase versicolor foram acompanhados por um período de 12 meses para observarmos o número de recidivas da doença. RESULTADOS: A pitiríase versicolor, após um tratamento adequado, apresentou três tipos de evolução clínica num período de 12 meses: pitiríase versicolor sem nenhum episódio de recidiva (32,35 por cento); pitiríase versicolor recidivante, com um a quatro episódios de recidiva (52,94 por cento) devidos a fatores de predisposição relacionados; e pitiríase versicolor crônica, com mais de quatro episódios de recidiva (14,70 por cento) sem nenhuma relação com fatores de predisposição. CONCLUSÕES: A pitiríase versicolor apresentou uma evolução clínica de acordo com o número de episódios de recidiva da doença analisados durante um período de 12 meses que pode ser considerada da seguinte maneira: pitiríase versicolor com cura clínica e micológica, pitiríase versicolor recidivante e pitiríase versicolor crônica.


BACKGROUND: Pytiriasis versicolor is an infectious disease caused by several Malassezia species which has a tendency to become relapsing or chronic. OBJECTIVES: This study was conducted in an attempt to investigate the clinical course of pityriasis versicolor with regard to the number of relapses after a 12-month therapy and correlate this number with isolates of Malassezia species. MATERIAL AND METHODS: 102 patients with clinical and laboratory diagnosis of pityriasis versicolor were monitored for 12 months to investigate the number of relapsing episodes of the disease. RESULTS: After appropriate treatment, pityriasis versicolor presented three types of clinical course: pity - riasis versicolor without relapsing episodes (32.35 percent), relapsing pityriasis versicolor with one to four relapsing episodes (52.94 percent ) due to associated predisposing factors, and chronic pityriasis versicolor with more than four relapsig episodes (14.70 percent) with no relation to predisposing factors. CONCLUSIONS: The clinical course of pityriasis versicolor varied according to the number of relapsing episodes of the disease analyzed over a period of 12 months and can be classified as follows: pityriasis versiolor with clinical and mycological clearing, relapsing pityriasis versicolor and chronic pityriasis versicolor.

ABSTRACT

Mycetoma is a pathological process in which eumycotic (fungal) or actinomycotic causative agents from exogenous source produce grains. It is a localized chronic and deforming infectious disease of subcutaneous tissue, skin and bones. We report the first case of eumycetoma of the oral cavity in world literature. CASE REPORT: A 43-year-old male patient, complaining of swelling and fistula in the hard palate. On examination, swelling of the anterior and middle hard palate, with fistula draining a dark liquid was observed. The panoramic radiograph showed extensive radiolucent area involving the region of teeth 21-26 and the computerized tomography showed communication with the nasal cavity, suggesting the diagnosis of periapical cyst. Surgery was performed to remove the lesion. Histopathological examination revealed purulent material with characteristic grain. Gram staining for bacteria was negative and Grocott-Gomori staining for the detection of fungi was positive, concluding the diagnosis of eumycetoma. The patient was treated with ketoconazole for nine months, and was considered cured at the end of treatment. CONCLUSION: Histopathological examination, using histochemical staining, and direct microscopic grains examination can provide the distinction between eumycetoma and actinomycetoma accurately.


Micetoma é um processo patológico no qual agentes eumicóticos (fungos) ou actinomicóticos de origem exógena podem causar formação de grãos. É uma doença infecciosa localizada, crônica e deformante do tecido subcutâneo, pele e ossos. Relatamos o primeiro caso de eumicetoma da cavidade bucal da literatura mundial. RELATO DE CASO: Paciente masculino, de 43 anos, com queixa de edema e fístula no palato duro. Ao exame clínico, observava-se edema da região anterior e média de palato duro, com fístula drenando líquido escuro. A radiografia panorâmica mostrou área radiolúcida extensa, envolvendo a região dos dentes 21 ao 26 e a Tomografia computadorizada evidenciou comunicação com a cavidade nasal, sugerindo o diagnóstico de cisto periapical. Foi realizada cirurgia para remoção da lesão. O exame histopatológico revelou material purulento com grãos característicos. A coloração de Gram para pesquisa de bactérias foi negativa e a coloração de Gomori-Grocott para pesquisa de fungos foi positiva, concluindo o diagnóstico de eumicetoma. O paciente foi tratado com Cetoconazol durante nove meses, obtendo cura ao final do tratamento. CONCLUSÃO: O exame histopatológico, usando colorações histoquímicas, e o exame dos grãos por microscopia direta podem proporcionar adequada distinção entre eumicetoma e actinomicetoma.

ABSTRACT

INTRODUCTION: Histoplasmosis is a systemic mycosis endemic in Brazil, especially in the State of Rio Grande do Sul, where Histoplasma capsulatum was isolated from the soil. H. capsulatum may compromise unusual areas, including the oropharynx, particularly in patients presenting disseminated histoplasmosis; which is associated with a state of immunosuppression, such as AIDS. METHODS: During database analysis of a total of 265 cases of histoplasmosis, the medical records of 11 patients with histological or microbiological diagnoses of oral histoplasmosis (OH) between 1987 and 2008 were retrospectively reviewed. RESULTS: This work reports 11 cases of OH, the majority presenting histopathological or microbiological evidence of disseminated histoplasmosis (DH). In the patients with DH, OH was the first manifestation of histoplasmosis. Five of the 11 patients discussed were HIV-seropositive with clinical and laboratory findings of AIDS. Four patients presented active pulmonary tuberculosis concomitant with histoplasmosis. Treatment was based on the use of itraconazole and amphotericin B deoxycholate. Eight patients responded successfully to therapy after one year, two did not come back for reevaluation and one died despite adequate therapy. CONCLUSIONS: Oral histoplasmosis is closely associated with immunosuppression status, especially in patients presenting AIDS; moreover, in many cases, OH is the first sign of disseminated histoplasmosis.


INTRODUÇÃO: Histoplasmose é uma micose sistêmica, endêmica no Brasil, especialmente no Estado do Rio Grande do Sul, onde Histoplasma capsulatum foi isolado do solo. H. capsulatum pode acometer áreas não-usuais, como cavidade orofaríngea, particularmente em pacientes com histoplasmose disseminada, por sua vez, associada com estado de imunossupressão, como na AIDS. MÉTODOS: A partir de 265 casos de histoplasmose em um banco de dados de um laboratório de micologia, foram analisados retrospectivamente 11 prontuários de pacientes com diagnóstico histológico ou microbiológico de histoplasmose oral (HO) entre 1987 e 2008. RESULTADOS: Reportamos neste trabalho onze casos de HO, a grande maioria com evidências histopatológicas e microbiológicas de histoplasmose disseminada (HD). Nos pacientes com HD, HO foi a primeira manifestação de histoplasmose. Cinco dos onze casos relatados eram portadores do vírus do HIV, todos com diagnóstico clínico e laboratorial de AIDS. Quatro pacientes do total tinham concomitantemente tuberculose pulmonar e histoplasmose. Tratamento foi baseado no uso de itraconazol e anfotericina B principalmente. Oito pacientes tiveram sucesso terapêutico após um ano, dois não retornaram para reavaliação e um faleceu apesar da adequada terapia antifúngica. CONCLUSÕES: Histoplasmose oral está associada muitas vezes com estado de imunossupressão, especialmente em pacientes com AIDS. Em muitos casos pode representar o primeiro sinal indicativo de histoplasmose disseminada.

ABSTRACT

INTRODUCTION: Sporotrichosis is the most common subcutaneous mycosis observed in Brazil and it is generally consequent to a little trauma caused by vegetal particles or spines which inoculate the fungi in the subcutaneous area. Although sporotrichosis had been frequently mentioned with armadillo hunting this form has not been widely reported in Brazil until now. In this study we report ten cases of sporotrichosis evolving the armadillo's hunting diagnosed in some towns located in the central and west regions of Rio Grande do Sul State. METHODS: The cases were established based on clinical and classic mycological laboratorial techniques. The susceptibility tests were conducted by microdilution technique according to M38-A2 CLSI documents. RESULTS: Ten cases of sporotrichosis associated with armadillo hunting detected in the State of Rio Grande do Sul were diagnosed by mycological methods. The susceptibility tests of Sporothrix schenckii isolates to antifungal agents itraconazole, ketoconazole and terbinafine showed that all the isolates were susceptible. CONCLUSIONS: The paper discusses some cultural aspects related to hunting of this wild animal as well as possible causes of this unexpected occurrence in southern Brazil.


INTRODUÇÃO: A esporotricose constitui-se na micose subcutânea mais frequentemente observada e, na maioria dos casos, a infecção é decorrente de pequenos traumas envolvendo fragmentos vegetais ou espinhos que inoculam o fungo no tecido subcutâneo. Embora frequentemente relacionada a caça a tatus, esta ocorrência tem sido raramente relatada no Brasil. Neste estudo relatamos dez casos envolvendo esta prática, observados em várias cidades das regiões centro e oeste do Estado do Rio Grande do Sul. MÉTODOS: o diagnóstico clínico foi confirmado pelos métodos clássicos de cultura em ágar Mycobiotic, identificação micromorfológica seguida de reversão a fase leveduriforme em ágar BHI. Os testes de suscetibilidade foram realizados pela técnica de microdiluição em caldo, de acordo com as normas estabelecidas pelo documento CLSI M38-A2 (2008). RESULTADOS: A esporotricose, decorrente de lesões causadas pela caça ao tatu foi confirmada pelo métodos microbiológicos. Os testes de suscetibilidade indicaram que todos os isolados eram sensíveis ao itraconazol, cetoconazol e terbinafina. CONCLUSÕES: O artigo discute aspectos ambientais e culturais relacionados a caça a este animal silvestre bem como àqueles relacionados a esta inesperada ocorrência.

ABSTRACT

The treatment of choice for Cushing's syndrome remains surgical. The role for medical therapy is twofold. Firstly it is used to control hypercortisolaemia prior to surgery to optimize patient's preoperative state and secondly, it is used where surgery has failed and radiotherapy has not taken effect. The main drugs used inhibit steroidogenesis and include metyrapone, ketoconazole, and mitotane. Drugs targeting the hypothalamic-pituitary axis have been investigated but their roles in clinical practice remain limited although PPAR-gamma agonist and somatostatin analogue som-230 (pasireotide) need further investigation. The only drug acting at the periphery targeting the glucocorticoid receptor remains Mifepristone (RU486). The management of Cushing syndrome may well involve combination therapy acting at different pathways of hypercortisolaemia but monitoring of therapy will remain a challenge.


O tratamento de escolha para a síndrome de Cushing ainda é a cirurgia. O papel da terapia medicamentosa é duplo: ele é usado para controlar o hipercortisolismo antes da cirurgia e otimizar o estado pré-operatório do paciente e, adicionalmente, quando ocorre falha cirúrgica e a radioterapia ainda não se mostrou efetiva. Os principais medicamentos são empregados para inibir a esteroidogênese e incluem: metirapona, cetoconazol e mitotano. Medicamentos visando o eixo hipotálamo-hipofisário têm sido investigados, mas seu papel na prática clínica permanece limitado, embora o agonista PPAR-gama e análogo de somatostatina, som-230 (pasireotídeo), requeira estudos adicionais. A única droga que age perifericamente no receptor glicocorticóide é a mifepristona (RU486). O manejo da síndrome de Cushing deve envolver uma combinação terapêutica atuando em diferentes vias da hipercortisolemia, mas o monitoramento dessa terapia ainda permanece um desafio.

ABSTRACT

GH responses to ghrelin, GHRP-6, and GHRH in Cushing’s disease (CD) are markedly blunted. There is no data about the effect of reduction of cortisol levels with steroidogenesis inhibitors, like ketoconazole, on GH secretion in CD. ACTH levels during ketoconazole treatment are controversial. The aims of this study were to compare the GH response to ghrelin, GHRP-6, and GHRH, and the ACTH and cortisol responses to ghrelin and GHRP-6 before and after one month of ketoconazole treatment in 6 untreated patients with CD. Before treatment peak GH (mg/L; mean ± SEM) after ghrelin, GHRP-6, and GHRH administration was 10.0 ± 4.5; 3.8 ± 1.6, and 0.6 ± 0.2, respectively. After one month of ketoconazole there was a significant decrease in urinary cortisol values (mean reduction: 75 percent), but GH responses did not change (7.0 ± 2.0; 3.1 ± 0.8; 0.9 ± 0.2, respectively). After treatment, there was a significant reduction in cortisol (mg/dL) responses to ghrelin (before: 30.6 ± 5.2; after: 24.2 ± 5.1). No significant changes in ACTH (pg/mL) responses before (ghrelin: 210.9 ± 69.9; GHRP-6: 199.8 ± 88.8) and after treatment (ghrelin: 159.7 ± 40.3; GHRP-6: 227 ± 127.2) were observed. In conclusion, after short-term ketoconazole treatment there are no changes in GH or ACTH responses, despite a major decrease of cortisol levels. A longer period of treatment might be necessary for the recovery of pituitary function.


Na doença de Cushing (DC), as respostas do GH à ghrelina, ao GHRP-6 e ao GHRH estão diminuídas. Não existem dados sobre o efeito da redução dos níveis de cortisol, após cetoconazol, na secreção de GH na DC. Nessa situação, os níveis de ACTH são variáveis. Os objetivos do estudo são comparar as respostas do GH à administração de ghrelina, GHRP-6 e GHRH, e de ACTH e cortisol à ghrelina e ao GHRP-6 antes e após um mês de tratamento com cetoconazol em 6 pacientes com DC não tratados. Antes do tratamento, o pico de GH (mg/L; média ± EPM) após a administração de ghrelina, GHRP-6 e GHRH foi de 10,0 ± 4,5; 3,8 ± 1,6 e 0,6 ± 0,2, respectivamente. Após um mês de cetoconazol, ocorreu diminuição significante do cortisol urinário (redução média: 75 por cento), mas as respostas de GH permaneceram inalteradas (7,0 ± 2,0; 3,1 ± 0,8; 0,9 ± 0,2, respectivamente). Após o tratamento, houve redução da resposta de cortisol (mg/dL) à ghrelina (antes: 30,6 ± 5,2; após: 24,2 ± 5,1), mas não ocorreram mudanças nas respostas de ACTH (pg/mL) (ghrelina antes: 210,9 ± 69,9; após: 159,7 ± 40,3; GHRP-6 antes: 199,8 ± 88,8; após: 227 ± 127,2). Assim, o tratamento a curto prazo com cetoconazol não modificou as respostas de GH ou ACTH, apesar da redução do cortisol. Para a recuperação da função hipofisária deve ser necessário um período de tratamento maior.

ABSTRACT

El síndrome de Cushing (SC) es un trastorno grave que requiere frecuentemente tratamiento medicamentoso. Cincuenta y cuatro pacientes (44 mujeres, 10 varones) de 14-63 años de edad con SC, recibieron ketoconazol (KTZ) previo a cirugía (n=27), como complemento luego de cirugía y/o radioterapia (n=16), o como tratamiento primario (n=11). La dosis de mantenimiento fue de 600 (500 - 600) mg/día (mediana-IC95) durante 15 días a 13 años. Los signos clínicos, hepatograma y cortisol libre urinario (CLU) fueron evaluados antes y durante tratamiento con KNZ. El CLU cayó a valores normales o subnormales en 85% de los pacientes, 5 a 150 días luego de iniciar el tratamiento; aún sin normalizar, el CLU disminuyó a 12-48% de los valores pre-tratamiento en el resto de los pacientes acompañándose de mejoría de los signos clínicos. Los efectos colaterales fueron: insuficiencia adrenal (18.5%), toxicidad hepática reversible (11%), "rash" cutáneo (5.5%) e intolerancia gástrica (3.7%); en 11% de los pacientes se observó un fenómeno de "escape". Veinticuatro pacientes (44.4%) fueron tratados por períodos prolongados, de uno a trece años. Este estudio confirma que el KTZ constituye un tratamiento eficaz y generalmente bien tolerado del SC, en particular: a) como preparación para cirugía b) en casos de hipercortisolismo residual luego de cirugía o en espera de resultados de radioterapia, c) como una alternativa razonable en pacientes con SC de origen desconocido y, d) como tratamiento crónico en casos de hipercortisolismo no resuelto luego de fracaso de las terapéuticas habituales.


Cushing's syndrome (CS) is a serious condition requiring drug management in diverse clinical settings. Fifty four patients (44 females, 10 males) with CS, aged 14-63, received ketoconazole (KTZ) prior to surgery (n= 27), as complementary therapy after surgery and/or radiotherapy (n= 16), or as primary treatment (n= 11). It was given at a 600 (500 - 600) mg/day (median - CI95) maintenance dose for periods ranging from 15 days to 13 years. Clinical signs, hepatic enzymes and urinary free cortisol (UFC) were evaluated before and during KTZ treatment. UFC normalised or decreased to subnormal values in 85% of the patients, in 5 to 150 days after starting treatment; although failing to normalise, UFC decreased to 12-48% of pre-treatment values in the remaining patients. Clinical signs improved throughout. Side effects were adrenal insufficiency (18.5%), reversible hepatic toxicity (11%), allergic skin rash (5.5%) and gastric intolerance (3.7%); in 11% of patients, an "escape phenomenon" was observed. Twenty-four out of the total (44.4%) were treated for prolonged periods, from one up to 13 years. In conclusion, this study confirms that KTZ is an effective and generally well tolerated treatment for CS particularly: a) shortly before surgery, b) because of persistent hypercortisolism after surgery or awaiting the results of radiotherapy, c) as a reasonable option in patients with CS of unknown aetiology and, d) as long-term therapy in any case of unsolved hypercortisolism after failure of current treatments.

ABSTRACT

Estudo de 38 crianças com paracoccidioidomicose, até 14 anos de idade, tratados por 24-30 meses, com um derivado sulfamídico ou cetoconazol, desde o início do tratamento ou em seguida ao uso da anfotericina B. Dados laboratoriais à admissão foram analisados e comparados com exames seqüenciais até 30 meses de acompanhamento. Anemia, eosinofilia e bilirrubinas e aminotransferases elevadas normalizaram-se, na maioria, até os três meses de tratamento e, hipoalbuminemia, até os seis meses, sugerindo que esses achados sejam bons parâmetros para o monitoramento da resposta terapêutica inicial. Leucócitos periféricos, velocidade de hemossedimentação, IgG e títulos sorológicos para o Paracoccidioides brasiliensis estavam elevados e normalizaram-se, freqüentemente, após nove a 12 meses de tratamento, o que sugere utilidade desses exames no monitoramento de todo o tratamento e enfatiza a necessidade de curso terapêutico prolongado da paracoccidioidomicose na infância.


The study of 38 children with paracoccidioidomycosis, aged up to 14, treated for 24 to 30 months with either a sulfonamide derivative or ketoconazole either alone or, after the use of amphotericin B. Laboratory data at admission were analyzed and compared with those of sequential tests after up to 30 months follow-up. Anemia, eosinophilia, increased bilirubin and aminotransferases normalized, in most patients, after three months treatment and hypoalbuminemia normalized after six months, suggesting that these laboratory findings are useful for monitoring early therapeutic response. Peripheral leucocytes, erythrocyte sedimentation rate, IgG, and serological titers for Paracoccidioides brasiliensis were increased and frequently normalized after nine to 12 months of treatment. They may be useful for monitoring the entire treatment and emphasize the need for long term treatment of paracoccidioidomycosis in children.

ABSTRACT

Os autores descrevem um caso de entomoftoromicose em paciente previamente saudável, que apresentou abscesso em nádega direita, evoluindo, após drenagem cirúrgica, para tumoração retroperitoneal. Após ressecção da massa, o paciente obteve melhora clínica, em uso de cetoconazol. A análise histopatológica evidenciou fenômeno de Splendore-Hoeppli, sugerindo infecção por Basidiobolus ranarum, uma zigomicose geralmente restrita ao tecido subcutâneo, com raro comprometimento gastrintestinal.
