RESUMO

BACKGROUND: Vulvovaginitis is common in women of reproductive age group characterized by purulent white discharge. The incidence of vulvovaginitis has risen recently due to the resistance of Candida species to commonly used antifungal agents and recurrent infections. OBJECTIVE: The study aimed to determine the prevalence, associated factors, and antifungal susceptibility patterns of vaginal candidiasis among pregnant women attending Bule Hora University Teaching Hospital. METHODS: A hospital-based cross-sectional study was conducted from May 2023 to August 2023. Using systematic random sampling, 317 pregnant women participated in the study. Sabouraud Dextrose Agar and Chromogenic Candida Differential Agar were used to isolate and identify Candida species from clinical samples. Antifungal susceptibility was performed using a modified disc diffusion method. Epi data version 4.6 was used for data entry and Statistical Packages for Social Sciences version 25 was used for statistical analysis. A P-value < 0.05 was declared statistically significant. RESULT: The prevalence of vaginal candidiasis was 26.8% (95%, CI 21.9-31.72%). History of using contraceptives (AOR = 5.03, 95%CI, 1.21-11.37), past vaginal candidiasis (AOR = 6, 95%CI, 1.61-12.92), pregnant women infected with human immunodeficiency virus (HIV) (AOR = 4.24, 95%CI, 1.23-14.14), diabetic mellitus (AOR = 2.17, 95%CI, 1.02-4.64), history of antibiotic use (AOR = 3.55, 95%CI, 1.67-12.75), pregnant women in third trimester (AOR = 8.72, 95%CI, 1.30-23.07), were the significantly associated factors for vaginal candidiasis. The study revealed that itraconazole, amphotericin B, and miconazole were the most effective antifungal drugs for all Candida isolates. CONCLUSION: The present study has identified a high prevalence of vaginal candidiasis among pregnant women. The isolated Candida species showed resistance to fluconazole, ketoconazole, and clotrimazole. Therefore, healthcare providers should increase awareness of the risks of Candida infections to reduce Candida species among pregnant women. Physicians should prescribe suitable medications based on antifungal drug test outcomes to treat pregnant women with vaginal candidiasis.

RESUMO

OBJECTIVES: This systematic review and meta-analysis aimed to evaluate the clinical and mycological effectiveness of mucoadhesives as vehicles for drugs or natural products in the treatment of oral candidiasis. MATERIALS AND METHODS: The search for articles was carried out in the Medline/PubMed, SCOPUS, EMBASE, Web of Science, Cochrane Library, and SciELO databases before August 2023. We selected the studies, extracted the data, evaluated the study quality, graded the evidence, performed the risk of bias, and carried out meta-analysis. RESULTS: A total of 389 potentially relevant articles were identified, and 11 studies (1869 participants) met the inclusion criteria of the systematic review. The overall risk of bias was considered low. The most common presentation of mucoadhesives was tablets, with miconazole being the most frequently drug used in the delivery system. Mucoadhesives demonstrated comparable efficacy with topical or systemic antifungal agents, with no significant differences between treatments in terms of clinical (RR = 0.907; 95CI = 0.3-1.297; p = 0.591; I2 = 64.648) or mycological (RR = 0.95; 95CI = 0.667-1.360; p = 0.789; I2 = 73.271) efficacy. CONCLUSIONS: Mucoadhesives may be a suitable alternative to conventional treatments, with the advantage of reducing the frequency of application by up to 5 times and the daily dosage by up to 20 times.

RESUMO

BACKGROUND: Oral thrush is the most common occurring fungal infection in the oral cavity in uncontrolled diabetic patients, it is treated by various antifungal drugs according to each case. This study aimed to evaluate the therapeutic effects of topical application of miconazole and miconazole-loaded chitosan nanoparticles in treatment of diabetic patients with oral candidiasis. METHODS: In this randomized controlled clinical trial. A total of 80 diabetic patients presenting with symptomatic oral candidiasis were randomly assigned into two treatment groups: miconazole and miconazole-loaded chitosan nanoparticles. The patients were treated for 28 days, and clinical assessments were conducted at baseline, 7, 14, 21 and 28 days. Clinical parameters, including signs and symptoms of oral candidiasis were evaluated and microbiological analysis was performed to determine the Candida species and assess their susceptibility to the antifungal agents. Statistical analysis was done to the categorical and numerical data using chi-square test and Kruskal Wallis test. RESULTS: The antifungal efficacy between the miconazole and miconazole-loaded chitosan nanoparticles (CS-MCZ) groups insignificant difference (P >  0.05) was observed. Both treatment modalities exhibited comparable effectiveness in controlling oral candidiasis symptoms and reducing Candida colonization as miconazole-loaded chitosan nanoparticles group showed a significant difference in the clinical improvement in respect of both signs and symptoms from baseline (70%) until the end of study at 28 days (5%) (P <  0.05) Moreover, miconazole-loaded chitosan nanoparticles, there was a significant reduction in the number of colonies forming units of Candida albicans from baseline until the end of the study at 28-day with P value <  0.000. CONCLUSIONS: This randomized controlled clinical trial and microbiological analysis demonstrate that both miconazole and miconazole-loaded chitosan nanoparticles are effective in the treatment of oral candidiasis in diabetic patients with no adverse reactions. TRIAL REGISTRATION: NCT06072716 with first registration first registration in 10/10/2023.

RESUMO

People with immune deficiency are at risk of developing infections caused by several bacterial and fungal species. In this work, chitosan-coated miconazole was developed by a simple sol-gel method. Miconazole is considered an effective drug to treat vaginal infection-causing bacteria and fungi. The coating of chitosan with miconazole nitrate showed the highest drug loading efficiency (62.43%) and mean particle size (2 µm). FTIR spectroscopic analysis confirmed the entrapment of miconazole nitrate into chitosan polymer. The antifungal result demonstrated that MN@CS microgel possessed notable anti-Aspergillus fumigatus and Candida albicans activity in lower doses. Antibacterial activity results revealed excellent bacterial growth inhibition of MN@CS microgel towards human skin infectious pathogens Escherichia coli and Staphylococcus aureus. The biocompatibility studies of In vitro cell viability and Artemia salina lethality assay suggested that MN@CS microgel is more biosafe and suitable for human external applications. In the future, it will be an efficient anti-inflammatory agent for the treatment of vaginal infections.

RESUMO

PURPOSE: Our previous clinical pilot study reported that miconazole (MCZ) prevented morbidity from surgical necrotizing enterocolitis (NEC). The present study re-investigated this effect in a long-term cohort over 20 years. METHODS: We conducted a retrospective cohort study from April 1998 to March 2020. A total of 1169 extremely low-birth-weight infants (ELBWIs) admitted to our neonatal intensive care unit, including 45 with NEC (3.8%), underwent surgery. Since 2002, protocol MCZ administration for 3 weeks has been applied for neonates born before 26 weeks' gestation or weighing under 1000 g. We compared the background characteristics and clinical outcomes between patients with and without MCZ administration. RESULTS: The morbidity rate decreased after applying the MCZ protocol, but no improvement in mortality was seen. A propensity score-matched analysis indicated that treated patients by MCZ showed a delay in developing surgical NEC by 12 days. The MCZ protocol also helped increase body weight at surgery. Prophylactic MCZ administration did not improve the neurological development of the language-social and postural-motor domains in the surgical NEC patients. But cognitive-adaptive domain caught up by a chronological age of 3 years old. CONCLUSIONS: Revising the protocol to extend the dosing period may improve the outcomes of surgical NEC after the onset.

RESUMO

OBJECTIVE: To evaluate the clinical efficacy of photodynamic therapy (PDT) as an adjunct or alternative to traditional antifungal drugs in the treatment of oral candidiasis, and to provide evidence-based medical evidence for its use in the treatment of oral candidiasis. METHODS: Computer combined with manual retrieval of China Academic Journals Full-text Database (CNKI), China Biomedical Literature Database (CBM), Chinese Science and Technology Journal Database (VIP), Wanfang Database, PubMed, Web of Science, Cochrane Library, Embase, Scopus retrieval for articles published before January 2023, basic information and required data were extracted according to the inclusion and exclusion criteria, and the Revman V5.4 software was used to conduct Meta-analysis of the included literature. RESULTS: A total of 11 articles were included, 7 of which used nystatin as an antifungal drug, 2 of which were combined treatment of PDT and nystatin, 2 of the remaining 4 articles were treated with fluconazole, and 2 were treated with miconazole. Meta results showed that PDT was superior to nystatin in reducing the number of oral candida colonies in the palate of patients MD = -0.87, 95%CI = (-1.52,-0.23), P = 0.008, the difference was statistically significant, and the denture site MD = -1.03, 95%CI = (-2.21, -0.15), P = 0.09, the difference was not statistically significant; compared with the efficacy of fluconazole, RR = 1.01, 95%CI = (0.56,1.83), P = 0.96; compared with miconazole RR = 0.55, 95%CI = (0.38, 0.81), P = 0.002; PDT combined with nystatin RR = 1.27, 95%CI = (1.06, 1.52), P = 0.01; recurrence rate RR = 0.28, 95%CI = (0.09, 0.88), P = 0.03. CONCLUSIONS: PDT was effective in the treatment of oral candidiasis; PDT was more effective than nystatin for the treatment of denture stomatitis in the palate, while there was no significant difference between the two for the denture site; The efficacy of PDT for oral candidiasis was similar to that of fluconazole; PDT was less effective than miconazole for oral candidiasis; Compared with nystatin alone, the combination of PDT and nystatin is more effective in treating oral candidiasis with less risk of recurrence.

RESUMO

BACKGROUND: Treatment of Malassezia pachydermatis dermatitis can be performed by systemic or topical route. As M. pachydermatis is located on the stratum corneum, topical therapy alone may be sufficient to resolve the infection. Owing to systemic antifungal resistance and adverse effects, topical treatment alone may improve treatment outcome. HYPOTHESIS/OBJECTIVES: To evaluate the efficacy of a topical spray composed of sodium benzoate, alcohol and botanical oils, compared to a shampoo containing 2% chlorhexidine gluconate and 2% miconazole nitrate for the treatment of Malassezia pachydermaitis dermatitis in dogs. ANIMALS: Sixteen client owned dogs diagnosed with symmetrical interdigital lesions as a result of secondary Malassezia dermatitis. METHODS: The study design was prospective, randomised and single-blinded, using a split body protocol. Malassezia yeasts were determined by cytology at the inclusion day (day0) and after treatment (day14). All dogs were treated during 14 days with both shampoo at one paw and spray on the other paw. RESULTS: At day 14 a reduction of Malassezia dermatitis was shown at both paws. No statistical difference was demonstrated between treatment with shampoo or spray. CONCLUSIONS AND CLINICAL IMPORTANCE: We could not show a difference in efficacy between application of the test spray once daily and the topical use of 2%miconazole/2%chlorhexidine shampoo every other day. No adverse effects were reported.


Contexte - Le traitement de la dermatite à Malassezia peut être réalisé par voie systémique ou topique. Comme M. pachydermatis est situé sur la couche cornée, un traitement topique seul peut suffire à résoudre l'infection. En raison de résistance antifongique systémique et d'effets indésirables, le traitement topique seul peut améliorer les résultats du traitement. Hypothèses/Objectifs - Évaluer l'efficacité d'un spray topique composé de benzoate de sodium, d'alcool et d'huiles végétales, par rapport à un shampooing contenant 2 % de gluconate de chlorhexidine et 2 % de nitrate de miconazole pour le traitement de la dermatite à Malassezia chez le chien. Animaux - Seize chiens appartenant à des clients ont reçu un diagnostic de lésions interdigitées symétriques à la suite d'une dermatite à Malassezia secondaire. Méthodes - La conception de l'étude était prospective, randomisée et en simple aveugle. Les levures Malassezia ont été évaluées par cytologie au jour de l'inclusion (jour0) et après traitement (jour14). Tous les chiens ont été traités pendant 14 jours avec du shampooing sur une patte et un spray sur l'autre patte. Résultats - Au jour 14, une réduction de la dermatite à Malassezia a été observée aux deux pattes. Aucune différence statistique n'a été mise en évidence entre le traitement shampooing ou spray. Conclusions et importance clinique - Nous n'avons pas pu montrer de différence d'efficacité entre l'application du spray test une fois par jour et l'utilisation topique du shampooing 2%miconazole/2%chlorhexidine tous les deux jours. Aucun effet indésirable n'a été signalé.


Introducción- el tratamiento de la dermatitis por Malassezia pachydermatis se puede realizar por vía sistémica o tópica. Como M. pachydermatis se encuentra en el estrato córneo, la terapia tópica sola puede ser suficiente para resolver la infección. Debido a la resistencia antifúngica sistémica y los efectos adversos, el tratamiento tópico podría mejorar los resultados terapeúticos. Hipótesis/Objetivos - Evaluar la eficacia de un spray tópico compuesto por Benzoato de Sodio, alcohol y aceites botánicos, en comparación con un champú que contiene gluconato de clorhexidina al 2% y nitrato de miconazol al 2% para el tratamiento de la dermatitis por M. Paquydermatis en perros. Animales- dieciséis perros de propietarios particulares diagnosticados con lesiones interdigitales simétricas como resultado de una dermatitis secundaria por Malassezia. Métodos- el diseño del estudio fue prospectivo, al azar y simple ciego, utilizando un protocolo de cuerpo dividido. La presencia de levaduras Malassezia se determinó mediante citología el día de inclusión (día 0) y después del tratamiento (día 14). Todos los perros fueron tratados durante 14 días con champú en una pata y spray en la otra pata. Resultados- en el día 14 se mostró una reducción de la dermatitis por Malassezia en ambas patas. No se demostró diferencia estadística entre el tratamiento con champú o spray. Conclusiones e importancia clínica- no pudimos demostrar una diferencia en la eficacia entre la aplicación del aerosol a prueba una vez al día y el uso tópico de champú con miconazol al 2%/clorhexidina al 2% en días alternos. No se detectaron efectos adversos.


Contexto - O tratamento da dermatite por Malassezia pachydermatis pode ser realizado por via sistêmica ou tópica. Como a M. pachydermatis fica localizada no estrato córneo, a terapia tópica unicamente pode ser suficiente para resolver a infecção. Devido à resistência antifúngica e aos efeitos adversos, terapia tópica em monoterapia pode melhorar o resultado do tratamento. Hipótese/Objetivos - Avaliar a eficácia de um spray tópico contendo benzoato de sódio, álcool e óleos botânicos, comparado a um shampoo de gluconato de clorexidina a 2% e nitrato de miconazol a 2% para o tratamento de dermatite por Malassezia pachydermaitis em cães. Animais - Dezesseis cães de clientes diagnosticados com lesões interdigitais simétricas resultantes de infecção secundária por Malassezia. Métodos - O delineamento do estudo foi prospectivo, randomizado e simples-cego, utilizando um protocolo de corpo dividido. As leveduras identificadas como Malassezia foram determinadas por citologia no dia da inclusão (dia 0) e após o tratamento (dia 14). Todos os cães foram tratados por 14 dias com shampoo em uma pata e spray na outra. Resultados - No dia 14, observou-se um declínio na dermatite por Malassezia em ambas as patas. Não houve diferença estatística entre o tratamento com shampoo ou spray. Conclusões e importância clínica - Não pudemos encontrar diferenças na eficácia entre a aplicação do spray teste uma vez ao dia e o uso tópico de um shampoo contendo 2%miconazol/2%clorexidine em dias alternados. Não foram relatados efeitos adversos.

RESUMO

Objective: To test the antibiotic susceptibility of vulvovaginal candidiasis pathogenic strains to 5 antifungal drugs commonly used in clinic. Methods: A total of 1 200 vulvovaginal candida patients from 23 gynecological and family planning outpatient departments in China were enrolled. Their vaginal secretions were collected for candida strain isolation and species identification. According to Clinical and Laboratory Standards Institute (CLSI) M27-S3, the sensitivity of 1 200 strains to clotrimazole, fluconazole, miconazole, itraconazole and nystatin was tested. Results: (1) The sensitivity and resistance of 1 200 vulvovaginal candidiasis pathogens to 5 antifungal drugs were statistically different (χ2=3 513.201, P<0.01). (2) All strains had higher sensitivity to nystatin [99.92% (1 199/1 200)], followed by miconazole [92.25% (1 107/1 200)] and clotrimazole [87.17% (1 046/1 200)]. All strains had higher resistance to fluconazole [69.17% (830/1 200)], while itraconazole was 50.83% (610/1 200). (3) There was no significant difference between candida albicans and non-candida albicans in drug sensitivity to nystatin (P=0.315) and miconazole (P=0.425). (4) Candida albicans and non-candida albicans showed different sensitivity to clotrimazole, fluconazole and itraconazole, respectively. Compared with non-candida albicans, candida albicans showed higher sensitivity to clotrimazole [susceptibility rate: 73.01% (165/226) vs 90.45% (881/974); P<0.001] and higher resistance to fluconazole [resistance rate: 50.88% (115/226) vs 73.41% (715/974); P<0.001]. Although the drug sensitivity of itraconazole was not high, the susceptibility rate of candida albicans to itraconazole was slightly higher than that of non-candida albicans [37.68% (367/974) vs 23.89% (54/226)], and the drug resistance rate was lower [49.28% (480/974) vs 57.52% (130/226)]. Conclusions: The sensitivity of 1 200 strains of candida to 5 antifungal drugs is significantly different, the sensitivity rate of nystatin, miconazole and clotrimazole are higher, but the resistance rate of fluconazole and itraconazole are higher. The sensitivity of candida albicans and non-candida albicans to the same drug is also significantly different. It is suggested that in clinical diagnosis and treatment, we should pay attention to the identification of candida and drug sensitivity test, so as to select antifungal drugs rationally.

RESUMO

Vulvovaginal candidiasis (VVC) is caused mainly by the opportunistic fungus Candida albicans, and its yeast to hyphae transition is considered a major virulence factor. Farnesol is a molecule that inhibits yeast to hyphae transition. The increased incidence of VVC has influenced a need for developing new therapeutic strategies. The objective was to develop a mucoadhesive nanostructured system composed of miconazole and farnesol co-encapsulated within chitosan nanoparticles. The miconazole presented a minimal inhibitory concentration (MIC) of 1 µg/ml against C. albicans. The farnesol was capable of inhibiting yeast to hyphae transition at levels greater or equal to 300 µM. The combination of miconazole and farnesol showed no change in miconazole MIC. Chitosan nanoparticles containing miconazole and farnesol were prepared by ionic gelation and showed favorable characteristics for use on mucous membranes. They showed size variation and polydispersion index (PDI) after 30 days, but the efficiency of drug encapsulation was maintained. Regarding toxicity in cultured fibroblasts (BALB/c 3T3) the nanoparticles were considered nontoxic. The nanoparticles showed antifungal activity against the C. albicans strain used with MICs of 2.5 µg/ml and 2 µg/ml for nanoparticles containing miconazole or miconazole/farnesol, respectively. Nanoparticles containing farnesol inhibited yeast to hyphae transition at concentrations greater than or equal to 240 µM. The in vivo antifungal activity was assessed in the murine model for VVC. The results suggested that chitosan nanoparticles containing miconazole and farnesol were effective at inhibiting fungal proliferation. Additionally, chitosan nanoparticles containing farnesol were capable of decreasing the pathogenicity of infection, demonstrated through the absence of inflammation.

RESUMO

Cutaneous candidiasis is a common skin disease, and several treatments have been investigated within the last fifty years. Yet, systematic reviews are lacking, and evidence-based topical and systemic treatment strategies remain unclear. Thus, the aim of this review was to summarize efficacy and adverse effects of topical and oral therapies for cutaneous candidiasis in all age groups. Two individual researchers searched PubMed and EMBASE for 'cutaneous candidiasis' and 'cutaneous candidiasis treatment', 'intertrigo', 'diaper dermatitis' and 'cheilitis'. Searches were limited to 'English language', 'clinical trials' and 'human subjects', and prospective clinical trials published in abstracts or articles were included. In total, 149 studies were identified, of which 44 were eligible, comprising 41 studies of 19 topical therapies and four studies of three systemic therapies for cutaneous candidiasis. Topical therapies were investigated in infants, children, adolescents, adults and elderly, while studies of systemic therapies were limited to adolescents and adults. Clotrimazole, nystatin and miconazole were the most studied topical drugs and demonstrated similar efficacy with complete cure rates of 73%-100%. Single-drug therapy was as effective as combinations of antifungal, antibacterial and topical corticosteroid. Four studies investigated systemic therapy, and oral fluconazole demonstrated similar efficacy to oral ketoconazole and topical clotrimazole. Limitations to this review were mainly that heterogeneity of studies hindered meta-analyses. In conclusions, clotrimazole, nystatin and miconazole were the most studied topical drugs and demonstrated equal good efficacy and mild adverse effects similar to combinations of antifungal, antibacterial and topical corticosteroids. Oral fluconazole was as effective as topical clotrimazole and is the only commercially available evidence-based option for systemic treatment of cutaneous candidiasis.

RESUMO

A 6 month-old-female infant from Bahrain visiting Germany with her family for a holiday was seen by us for extensive dermatophytosis of the back, buttocks, chest and groins. Topical treatment by terbinafine for over 2 months was not successful. Other family members including adults and children were treated in Bahrain with topical antifungals and oral voriconazole which was not helpful. Mycological examination performed in Germany revealed the detection of the zoophilic dermatophyte Trichophyton (T.) mentagrophytes. The newly described genotype VIII within the species T. mentagrophytes was identified by sequencing of the "internal transcribed spacer" (ITS) region of the fungal rDNA. This genotype of T. mentagrophytes is the main causative agent of the current epidemic of chronic recalcitrant dermatophytoses in India. Transmission of this Indian genotype of T. mentagrophytes to other countries due to globalization is a serious issue to be considered. Moreover, a significant percentage of these Indian T. mentagrophytes strains are resistant to terbinafine both in vitro and by the way of genetic point mutations in the squalene epoxidase (SQLE) gene. Some are also found to be partially resistant against itraconazole and voriconazole. The point mutation TTC/TTA was found by SQLE mutation analysis in this particular T. mentagrophyte isolate from Bahrain. This point mutation is closely associated with F397L amino acid substitution of the enzyme indicative of in vitro resistance of the dermatophyte against terbinafine. The girl was successfully treated by topical miconazole and later by ciclopirox olamine. This is the first report on an infection due to a terbinafine-resistant T. mentagrophytes strain of the ITS genotype VIII from India in Germany.

RESUMO

BACKGROUND: Candidiasis is one of the most common opportunistic oral infections that presents different acute and chronic clinical presentations with diverse diagnostic and therapeutic approaches. The present study carries out a bibliographic review on the therapeutic tools available against oral candidiasis and their usefulness in each clinical situation. MATERIAL AND METHODS: Recent studies on treatment of oral candidiasis were retrieved from PubMed and Cochrane Library. RESULTS: Nystatin and miconazole are the most commonly used topical antifungal drugs. Both antifungal drugs are very effective but need a long time of use to eradicate the infection. The pharmacological presentations of miconazole are more comfortable for patients but this drug may interact with other drugs and this fact should be assessed before use. Other topical alternatives for oral candidiasis, such as amphotericin B or clotrimazole, are not available in many countries. Oral fluconazole is effective in treating oral candidiasis that does not respond to topical treatment. Other systemic treatment alternatives, oral or intravenous, less used are itraconazole, voriconazole or posaconazole. Available novelties include echinocandins (anidulafungin, caspofungin) and isavuconazole. Echinocandins can only be used intravenously. Isavuconazole is available for oral and intravenous use. Other hopeful alternatives are new drugs, such as ibrexafungerp, or the use of antibodies, cytokines and antimicrobial peptides. CONCLUSIONS: Nystatin, miconazole, and fluconazole are very effective for treating oral candidiasis. There are systemic alternatives for treating recalcitrant infections, such as the new triazoles, echinocandins, or lipidic presentations of amphotericin B.

RESUMO

INTRODUCTION: Improving axonal outgrowth and remyelination is crucial for peripheral nerve regeneration. Miconazole appears to enhance remyelination in the central nervous system. In this study we assess the effect of miconazole on axonal regeneration using a sciatic nerve crush injury model in rats. METHODS: Fifty Sprague-Dawley rats were divided into control and miconazole groups. Nerve regeneration and myelination were determined using histological and electrophysiological assessment. Evaluation of sensory and motor recovery was performed using the pinprick assay and sciatic functional index. The Cell Counting Kit-8 assay and Western blotting were used to assess the proliferation and neurotrophic expression of RSC 96 Schwann cells. RESULTS: Miconazole promoted axonal regrowth, increased myelinated nerve fibers, improved sensory recovery and walking behavior, enhanced stimulated amplitude and nerve conduction velocity, and elevated proliferation and neurotrophic expression of RSC 96 Schwann cells. DISCUSSION: Miconazole was beneficial for nerve regeneration and functional recovery after peripheral nerve injury. Muscle Nerve 57: 821-828, 2018.

RESUMO

BACKGROUND: Spontaneous abortions are the most common complication of pregnancy. Clotrimazole and miconazole are widely used vaginal-antimycotic agents used for the treatment of vulvovaginal candidiasis. A previous study has suggested an increased risk of miscarriage associated with these azoles, which may lead health professionals to refrain from their use even if clinically indicated. OBJECTIVE: The aim of the current study was to assess the risk for spontaneous abortions following first trimester exposure to vaginal antimycotics. STUDY DESIGN: A historical cohort study was conducted including all clinically apparent pregnancies that began from January 2003 through December 2009 and admitted for birth or spontaneous abortion at Soroka Medical Center, Clalit Health Services, Beer-Sheva, Israel. A computerized database of medication dispensation was linked with 2 computerized databases containing information on births and spontaneous abortions. Time-varying Cox regression models were constructed adjusting for mother's age, diabetes mellitus, hypothyroidism, obesity, hypercoagulable or inflammatory conditions, recurrent miscarriages, intrauterine contraceptive device, ethnicity, tobacco use, and the year of admission. RESULTS: A total of 65,457 pregnancies were included in the study: 58,949 (90.1%) ended with birth and 6508 (9.9%) with a spontaneous abortion. Overall, 3246 (5%) pregnancies were exposed to vaginal antimycotic medications until the 20th gestational week: 2712 (4.2%) were exposed to clotrimazole and 633 (1%) to miconazole. Exposure to vaginal antimycotics was not associated with spontaneous abortions as a group (crude hazard ratio, 1.11; 95% confidence interval, 0.96-1.29; adjusted hazard ratio, 1.11; 95% confidence interval, 0.96-1.29) and specifically for clotrimazole (adjusted hazard ratio, 1.05; 95% confidence interval, 0.89-1.25) and miconazole (adjusted hazard ratio, 1.34; 95% confidence interval, 0.99-1.80). Furthermore, no association was found between categories of dosage of vaginal antimycotics and spontaneous abortions. CONCLUSION: Exposure to vaginal antimycotics was not associated with spontaneous abortions.

RESUMO

The liver fluke Opisthorchis felineus (Rivolta, 1884) is the causative agent of opisthorchiasis felinea in Eurasia. Opisthorchiasis is a serious human and fish-eating animal's disease affecting bile ducts and the gall bladder. Currently, the main drug for specific therapy of opisthorchiasis is praziquantel. We have previously shown that azole inhibitors of O. felineus cytochrome P450 significantly reduced survival of the worms in vitro. Here, we studied in vitro anthelmintic effects of drug combinations involving azole substances approved by the US Food and Drug Administration together with praziquantel against adult or juvenile O. felineus liver flukes. A synergistic interaction was shown for praziquantel-clotrimazole (CI = 0.68) combination and for praziquantel-miconazole (CI = 0.68) combination against adult helminths in vitro. Praziquantel-miconazole (CI = 0.30) had a strongly synergistic effect against newly excysted metacercariae. We also tested anthelmintic effects of azole substances and their combinations with praziquantel in vivo in an animal model of chemotherapy. The treatment of juvenile worms (1 day postinfection) with 100 mg/kg miconazole resulted in a worm burden reduction (WBR) of 37.5% (P = 0.049), with 100 mg/kg clotrimazole causing a WBR of 31.25% (P = 0.025). The treatment of adult worms (5-6 weeks postinfection) with 100 mg/kg or 200 mg/kg miconazole yielded a WBR of 23.8% (P = 0.01) and 21.4% (P = 0.006), respectively. When praziquantel was administered together with clotrimazole or with miconazole, a WBR slightly greater than the effect of ED50 praziquantel was observed (WBR of 59.5 and 54.7%, respectively).In conclusion, the synergistic effect of the praziquantel-clotrimazole and praziquantel-miconazole combinations observed in vitro was not confirmed in vivo. Thus, this combination chemotherapy revealed no benefits over praziquantel monotherapy in the treatment of opisthorchiasis felinea.

RESUMO

Background: Evidence suggests that specific vaginal bacteria associated with bacterial vaginosis (BV) may increase the risk of adverse health outcomes in women. Among women participating in a randomized, double-blinded trial, we assessed the effect of periodic presumptive treatment (PPT) on detection of select vaginal bacteria. Methods: High-risk women from the United States and Kenya with a recent vaginal infection received intravaginal metronidazole 750 mg plus miconazole 200 mg or placebo for 5 consecutive nights each month for 12 months. Vaginal fluid specimens were collected via polyester/polyethylene terephthalate swabs every other month and tested for bacteria, using quantitative polymerase chain reaction (PCR) assays targeting the 16S ribosomal RNA gene. The effect of PPT on bacterium detection was assessed among all participants and stratified by country. Results: Of 234 women enrolled, 221 had specimens available for analysis. The proportion of follow-up visits with detectable quantities was lower in the PPT arm versus the placebo arm for the following bacteria: BVAB1, BVAB2, Atopobium vaginae, Leptotrichia/Sneathia, and Megasphaera. The magnitude of reductions was greater among Kenyan participants as compared to US participants. Conclusions: Use of monthly PPT for 1 year reduced colonization with several bacteria strongly associated with BV. The role of PPT to improve vaginal health should be considered, and efforts to improve the impact of PPT regimens are warranted.

RESUMO

In an effort to increase the efficacy of topical medications for treating onychomycosis, several new nail penetration enhancers were recently developed. In this study, the ability of 10% (wt/wt) miconazole nitrate combined with a penetration enhancer formulation to permeate the nail is demonstrated by the use of a selection of in vitro nail penetration assays. These assays included the bovine hoof, TurChub zone of inhibition, and infected-nail models.

RESUMO

A female North American porcupine ( Erethizon dorsatum ) was evaluated for a unilateral pedal crusting and alopecic dermatopathy. Fungal culture and histopathology testing revealed Microsporum gypseum dermatophytosis. Treatment with topical miconazole was initiated and then discontinued after 9 days and changed to oral terbinafine. Twenty-eight days after initial examination, clinical signs were improving, and fungal cultures of the front foot, muzzle, and noninfected area along the dorsum were negative for M. gypseum. Visual exams were conducted on a regular basis. Eighty-three days after initial evaluation, clinical signs had completely resolved and repeat fungal cultures were negative. One of the animal's keepers was suspected to have acquired a dermal fungal infection 3 days after contact with this porcupine, and lesions had resolved after treatment with topical ketoconazole. To the authors' knowledge, this is the first report of M. gypseum diagnosed and treated in a captive North American porcupine. Veterinary staff and zookeepers should be aware of this potentially zoonotic infection.

RESUMO

The objective of this study is to assess the efficacy and safety of miconazole for treating oral candidiasis. Twelve electronic databases were searched for randomized controlled trials evaluating treatments for oral candidiasis and complemented by hand searching. The clinical and mycological outcomes, as well as adverse effects, were set as the primary outcome criteria. Seventeen trials were included in this review. Most studies were considered to have a high or moderate level of bias. Miconazole was more effective than nystatin for thrush. For HIV-infected patients, there was no significant difference in the efficacy between miconazole and other antifungals. For denture wearers, microwave therapy was significantly better than miconazole. No significant difference was found in the safety evaluation between miconazole and other treatments. The relapse rate of miconazole oral gel may be lower than that of other formulations. This systematic review and meta-analysis indicated that miconazole may be an optional choice for thrush. Microwave therapy could be an effective adjunct treatment for denture stomatitis. Miconazole oral gel may be more effective than other formulations with regard to long-term results. However, future studies that are adequately powered, large-scale, and well-designed are needed to provide higher-quality evidence for the management of oral candidiasis.
