Instability of tear film and loss of meibomian glands in patients with acne vulgaris / Instabilidade do filme lacrimal e perda de glândulas meibomianas em pacientes com acne vulgaris

ABSTRACT Purpose: In this prospective study, we compared ocular clinical variables in patients with acne vulgaris with those of healthy controls. These variables included tear film break-up time, meibomian gland dropout rate, and anterior chamber parameters. Methods: Our sample comprised 73 eyes from 73 patients with acne vulgaris and 67 eyes from 67 healthy controls. All participants underwent a non-invasive first tear film break-up time test and the average tear film break-up time was evaluated. Meibography was used to identify any meibomian gland dropout. The parameters of the cornea and anterior chamber were measured using Scheimpflug topography imaging. Finally, the ocular surface disease index questionnaire was administered to score each participant on their subjective experience of ocular complaints. Results: The noninvasive first tear film break-up time values of the acne vulgaris Group and the control Group were 4.7 ± 2.8 and 6.4 ± 3.5 sec, respectively. There was a significant difference between the groups (p=0.016). The number of eyes with tear break-up at any time during the measurement period was also significantly higher in the acne Group (p=0.018). In the acne vulgaris Group, the mean meibomian gland dropout rates were 33.21 ± 15.5% in the upper lids and 45.4 ± 14.5% in the lower lids. In the control group, these rates were 15.7 ± 6.9% and 21 ± 9.7% respectively. Dropout was significantly higher in the acne group for both the upper and lower lids (p=0.000). Conclusion: We found impaired tear stability in patients with acne vulgaris and a high rate of meibomian gland dropout. These glands play a key role in tear stability and their dropout is likely to result in evaporative dry eye. Measurement of the variables in this study allows objective diagnosis of this condition using a non-invasive, dye-free methodology, with minimum contact.

RESUMO Objetivo: Neste estudo prospectivo, pacientes com acne vulgaris e indivíduos saudáveis do grupo controle foram comparados em relação ao tempo de ruptura do filme lacrimal, taxa de abandono de glândulas meibomianas e parâmetros da câmara anterior, usando o tempo de ruptura do filme lacrimal topográfico não invasivo, meibografia não invasiva e fotografia de Scheimpflug, respectivamente. Métodos: Setenta e três olhos de 73 pacientes com acne vulgaris e 67 olhos de 67 indivíduos saudáveis foram incluídos. Todos os participantes submetidos ao primeiro tempo de ruptura do filme lacrimal não-invasivo e ao tempo médio de ruptura do filme lacrimal não-invasivo foram avaliados pelo uso do tempo de ruptura do filme lacrimal; perda de glândulas meibomianas foram avaliadas por meibografia; os parâmetros da córnea e da câmara anterior foram medidos por fotografia de Scheimpflug; e, finalmente, as queixas oculares subjetivas foram pontuadas com o uso do questionário do Indice de doenças de superfície ocular. Resultados: Os valores do tempo de ruptura do primeiro filme lacrimal não-invasivo do Grupo com acne vulgaris e do Grupo controle foram 4,7 ± 2,8 e 6,4 ± 3,5 segundos, respectivamente, refererindo-se a uma diferença significativa entre os valores dos grupos (p=0,016). Qualitativamente, o número de olhos com ruptura lacrimal a qualquer momento durante o período de medição foi significativamente maior no grupo de pacientes. (p=0,018). No Grupo com acne vulgaris, a perda de glândulas meibomianas nas pálpebras superiores foi de 33,21 ± 15,5% e nas pálpebras inferiores foi de 45,4 ± 14,5%; por outro lado, no Grupo controle foi de 15,7 ± 6,9% e 21 ± 9,7% respectivamente; ambos os casos referem-se a uma diferença significativa entre os grupos (p=0,000). Conclusão: Encontramos estabilidade comprometida do filme lacrimal em pacientes com acne vulgaris. No entanto, o comprometimento foi de grau muito menor, em comparação com a taxa de perda das glândulas meibomianas que desempenham um papel fundamental na estabilidade do filme lacrimal. Esta condição pode ser documentada de forma objetiva - uma metodologia parcialmente sem contato, totalmente não-invasiva e livre de corantes.

Una carga ignorada del acné en adolescentes: el bienestar psicosocial de la familia / An overlooked burden of acne in adolescents: The psychosocial wellbeing of their families

Introducción: El acné vulgar se asocia significativamente con un incremento en la carga de cuidados y tiene un impacto importante sobre la calidad de vida (CV) y la autoestima de los afectados. El objetivo de nuestro estudio fue evaluar la CV de los adolescentes con acné y sus familiares, así como la asociación entre la calidad de vida y la gravedad del acné, la respuesta al tratamiento, la duración del acné y la región del cuerpo afectada. Material y métodos: La muestra incluyó a un total de 100 adolescentes con acné, 100 controles sanos y sus padres. Se utilizaron la escala global de severidad del acné, el índice dermatológico de calidad de vida infantil (CDLQI) y el índice dermatológico de calidad de vida familiar (FDLQI). Resultados: La puntuación media de los pacientes en el CDLQI fue de 7,89 (desviación estándar [DE]: 5,43) y la puntuación media de sus familiares en el FDLQI de 6,01 (DE: 6,11). La puntuación media de los controles sanos en el CDLQI fue de 3,92 (DE: 3,88) y la puntuación media de sus familiares en el FDLQI fue de 2,12 (DE: 2,91). Hubo diferencias estadísticamente significativas entre los grupos de casos y de control en las puntuaciones en el CDLQI y el FDLQI (p<0,001). También se encontraron diferencias estadísticamente significativas en las puntuaciones del CDLQI según la duración del acné y la respuesta al tratamiento. Conclusiones: En los pacientes con acné y sus familiares la calidad de vida era inferior en comparación con los controles sanos. El acné se asoció a una merma en la CV familiar. La evaluación de la CV de la familia además de la del paciente puede contribuir a mejorar el manejo del acné vulgar. (AU)

Introduction: Acne vulgaris is significantly associated with an increased burden of care and has an important impact on the quality of life (QoL) and self-esteem of affected individuals. We aimed to assess the QoL of adolescents with acne and their families as well as the association of QoL with acne severity, treatment response, duration of acne and localization of lesions. Material and methods: The sample included a total of 100 adolescents with acne vulgaris, 100 healthy controls and their parents. We collected data on sociodemographic characteristics, presentation of acne, duration of acne, treatment history, treatment response, and parental sex. We used the Global Acne Severity scale, Children's Dermatology Life Quality Index (CDLQI), and the Family Dermatology Life Quality Index (FDLQI). Results: In the group of patients with acne, the mean CDLQI score in the patients was 7.89 (SD, 5.43) and the mean FDLQI score in the parents was 6.01 (SD, 6.11). In the control group, the mean CDLQI score in healthy controls was 3.92 (SD, 3.88) and the mean FDLQI score in their family members was 2.12 (SD, 2.91). We found a statistically significant difference between the acne and control groups in CDLQI and FDLQI scores (P<.001). There were also statistically significant differences in the CDLQI score based on the duration of acne and the response to treatment. Conclusions: Patients with acne and their parents had a decreased QoL compared with healthy controls. Acne was associated with impaired QoL in family members. Assessing QoL in the family in addition to that of the patient may allow an improved management of acne vulgaris. (AU)

Characterization of the newly isolated phage Y3Z against multi-drug resistant Cutibacterium acnes.

Cutibacterium acnes (C. acnes) is a symbiotic bacterium that plays an important role in the formation of acn e inflammatory lesions. As a common component of the acne microbiome, C. acnes phages have the potential to make a significant contribution to treating antibiotic-resistant strains of C. acnes. However, little is known about their genetic composition and diversity. In this study, a new lytic phage, Y3Z, infecting C. acne, was isolated and characterized. Electron microscopy analysis revealed this phage is a siphovirus. Phage Y3Z is composed of 29,160 bp with a GC content of 56.32%. The genome contains 40 open reading frames, 17 of which had assigned functions, while no virulence-related genes, antibiotic resistance genes or tRNA were identified. The one-step growth curve showed the burst size was 30 PFU (plaque-forming unit)/cell. And it exhibited tolerance over a broad range of pH and temperature ranges. Phage Y3Z could infect and lyse all C. acnes isolates tested, though the host range of PA6 was restricted to C. acnes. Based on the phylogenetic and comparative genomic analyses, Y3Z may represent a new siphovirus infecting C. acnes. Characterization of Y3Z will enrich our knowledge about the diversity of C. acnes phages and provide a potential arsenal for thetreatment of acne infection.

Assessments of the ocular surface and meibomian gland morphology in patients with treatment-naive acne vulgaris / Avaliação da superfície ocular e da morfologia das glândulas meibomianas em pacientes com acne vulgar virgens de tratamento

ABSTRACT Purpose: To investigate ocular surface and meibomian glands in patients with treatment-naive acne vulgaris. Methods: The Ocular Surface Disease Index (OSDI) questionnaire, invasive tear film breakup time, fluorescein staining of the ocular surface, and Schirmer II test were performed for all subjects. Total eyelid and meibomian gland secretion scores were assessed. Non-contact meibography was performed with the Sirius corneal topographic device. Results: The right eyes of 35 patients with acne vulgaris and 35 healthy volunteers were included the study. While the OSDI and staining scores were significantly higher in the acne group than in the control group (p=0.01 and p=0.003, respectively), the invasive tear film breakup time and Schirmer measurements were significantly lower in the acne group (p=0.000 and p=0.003, respectively). The total eyelid and meibomian gland secretion scores were also higher in the acne group than in the control group (p=0.003 and p=0.000, respectively). On the morphological evaluation of the meibomian glands, the thickening, thinning, tortuosity, and presence of ghost areas were statistically significantly more common in the acne vulgaris group than in the control group (p=0.000, p=0.001, p=0.05, and p=0.006, respectively). The percentage of the meibomian gland loss area was significantly high in the acne vulgaris group on both upper and lower meibography. The meibomian gland loss area positively correlated with total eyelid and meibomian gland secretion scores. Conclusion: Acne vulgaris may have a predisposition to meibomian gland dysfunction and ocular surface damage. Early recognition of meibomian gland and ocular surface alterations seems important, especially in acne vulgaris cases for which oral isotretinoin treatment is planned.

RESUMO Objetivo: Todos os indivíduos responderam ao questionário Ocular Surface Disease Index (OSDI) e tiveram avaliados o tempo de ruptura do filme lacrimal pelo método invasivo, a coloração da superfície ocular com fluoresceína e o teste de Schirmer II. Foram ainda avaliados o escore palpebral total e o de secreção das glândulas meibomianas. Foi realizada meibografia sem contato com um dispositivo topográfico corneano Sirius. Métodos: Todos os indivíduos responderam ao questionário Ocular Surface Disease Index (OSDI) e tiveram avaliados o tempo de ruptura do filme lacrimal pelo método invasivo, a coloração da superfície ocular com fluoresceína e o teste de Schirmer II. Foram ainda avaliados o escore palpebral total e o de secreção das glândulas meibomianas. Foi realizada meibografia sem contato com um dispositivo topográfico corneano Sirius. Resultados: Foram incluídos no estudo os olhos direitos de 35 voluntários com acne vulgar e 35 saudáveis. Os escores do Ocular Surface Disease Index e da coloração foram significativamente maiores no grupo com acne em comparação com o grupo controle (p=0,01 e p=0,003, respectivamente), mas o tempo de ruptura do filme lacrimal pelo método invasivo e as medidas do teste de Schirmer II foram significativamente menores (p=0,000 e p=0,003, respectivamente). O escore palpebral total e o escore de secreção das glândulas meibomianas também foram maiores no grupo com acne que no grupo controle (p=0,003 e p=0,000). Na avaliação morfológica das glândulas meibomianas, o espessamento, o afinamento, a tortuosidade e a presença de áreas fantasmas nas glândulas foram mais comuns no grupo acne vulgar que no grupo controle, com significância estatística (p=0,000, p=0,001, p=0,05 e p=0,006 respectivamente). A porcentagem da área de perdas das glândulas meibomianas foi significativamente mais alta no grupo com acne vulgar, tanto na meibografia superior quanto na inferior. A área de perda das glândulas meibomianas demonstrou uma correlação positiva com o escore palpebral total e com o escore de secreção das glândulas meibomianas. Conclusão: A acne vulgar pode levar a uma predisposição para a disfunção das glândulas meibomianas e para danos na superfície ocular. Parece ser importante reconhecer precocemente as alterações das glândulas meibomianas e da superfície ocular, especialmente nos casos de acne vulgar para os quais se planeja o tratamento oral com isotretinoína.

Acne and diet: a review of pathogenic mechanisms.

Acne is a chronic inflammatory disease of the pilosebaceous unit with multifactorial etiology. Abnormal proliferation of keratinocytes, altered sebum production, inflammation of the sebaceous follicle, and colonization by Cutibacterium acnes have been traditionally implicated. However, the diet has also been highlighted in the pathogenesis because of its direct relation with some biochemical markers and the transcription of specific genes associated with sebaceous gland activity, inflammation, and bacterial proliferation, which together promote the development of the disease, affect the severity of the condition, and modify its response to treatment.

El acné es una enfermedad inflamatoria crónica de la unidad pilosebácea de etiología multifactorial, en la que clásicamente se han implicado la proliferación anormal de queratinocitos, la producción alterada de sebo, la inflamación del folículo sebáceo y la colonización por Cutibacterium acnes. Sin embargo, también destaca la dieta en la patogenia al relacionarse directamente con la alteración de algunos marcadores bioquímicos y transcripción de ciertos genes que se asocian con la actividad de la glándula sebácea, la inflamación y la proliferación bacteriana, que en conjunto promueven el desarrollo de la enfermedad, afectan la gravedad del cuadro y modifican su respuesta al tratamiento.

Dermoscopy as an Auxiliary Tool in the Assessment of Malassezia Folliculitis: An Observational Study. / [Artículo traducido] Dermatoscopia como herramienta auxiliar en la evaluación de foliculitis por Malassezia: estudio observacional.

Malassezia folliculitis is an under-recognized entity commonly affecting the face and upper trunk. Clinical picture mimics acne vulgaris and diagnosis is challenging at times. Ten percent potassium hydroxide examination is usually performed to confirm the diagnosis. This study sought to describe the dermoscopic features in Malassezia folliculitis. Patients diagnosed clinically with Malassezia folliculitis and confirmed by 10% potassium hydroxide preparation were included in the study. Dermoscopy was performed with a videodermatoscope (Dino-Lite AM413ZT; Polarizer) from the most representative lesion. A total of 45 patients (M:F=1:0.8) were recruited. All patients had monomorphic papulo-pustular lesions. Itching was present in 64.4% patients. Dermoscopy reveled folliculocentricity (100%), perilesional background erythema (100%), dotted/linear/tortous vessels (88.9%), dirty white scaling (77.8%), hypopigmentation of hair follicle (64.4%), coiled/looped hairs (57.8%) and broken hairs (13.3%). In conclusion, dermoscopy shows typical features in Malassezia folliculitis and can serve as a office-based tool for identification of this entity.

Microagulhamento e fator de crescimento epidérmico (EGF) como estratégias para o tratamento de cicatrizes de acne / Microneedling and epidermal growth factor (EGF) as strategies for the acne scars

Introdução: a técnica de microagulhamento e aplicação de drug delivery transdérmico é indicada para o tratamento das cicatrizes de acne. Objetivos: avaliar a técnica de microagulhamento associada à aplicação de fator de crescimento epidérmico (EGF) em drug delivery. Métodos: ensaio clínico duplo-cego randomizado, com seleção de 30 pacientes, divididos em dois grupos: (1) duas sessões de microagulhamento com intervalo de 30 dias e (2) duas sessões de microagulhamento com mesmo intervalo e associação de drug delivery de EGF. Os pacientes foram submetidos à avaliação clínica (escala global de cicatriz de acne - Goodman e Baron, 2006), a avaliação por imagem multiespectral e por questionários de autopercepção. A avaliação estatística (Teste T Student, Teste SNK, análise de variância) foi realizada com o software estatístico SisVar (UFLA, 1996). Resultados: os grupos foram homogêneos quanto à idade, sexo e fototipo. Na avaliação clínica, houve redução dos escores de gravidade para ambos os grupos. A análise multiespectral revelou redução das porfirinas (p=0,0296) e melhora da textura da pele, ambas para o grupo 2. Conclusão: a terapia com microagulhamento foi eficaz e segura para o tratamento de cicatrizes de acne, e o EGF demonstrou ser um ativo promissor.
