Tratamiento homeopático para el vitiligo: un estudio piloto abierto observacional / Homoeopathic treatment of vitiligo: an open observational pilot study

Antecedentes: El vitiligo es un trastorno común de hipopigmentación que genera un impacto psicológico muy importante. En una clínica de atención ambulatoria en Bengala Occidental, India, se realizó una evaluación del tratamiento homeopático en individuos con vitiligo. Métodos: Se reclutaron 30 pacientes (edad media de 27 años; 57% femeninos) para un estudio piloto prospectivo abierto, y se manejaron con tratamiento homeopático individualizado durante seis meses. Se evaluó La eficacia del tratamiento a los tres y seis meses, utilizando el Índice de Puntuación del Área con Vitiligo (Vitiligo Area Scoring Index, VASI), la escala de la Comisión Europea de Vitiligo (Vitiligo European Task Force, VETF) y el Índice de Calidad de Vida en Dermatología (Dermatological Life Quality Index, DLQI), los cuales validaron el índice de mejoría tomando en cuenta el área, la intensidad, la extensión de La despigmentación de las lesiones de vitiligo y la calidad de vida (QoL). Resultados: Un total de 27 pacientes completaron el estudio; tres desertaron. Después de seis meses de tratamiento, la medida media de VASI mejoró significativamente en 0.1 unidades (p=0.003), de 0.8 (0.5, 1.5) a 0.7 (0.3, 0.8) en una escala de 0 (sin despigmentación) y 100 (completamente despigmentada). Del mismo modo, la media del VETF mejoró su puntuación por 2 unidades (p=0.0001), de 1 (0.1) a -1 (-1.0), y el marcador de estadificación varió de 1 (1.2) a 1 (0.1), p=0.002. La media de La puntuación total de DLQI disminuyó de 21 (17, 22) a 13.6 (10, 17), con variación de 7.4 (p=0.0001); dicha variación también fue corroborada por los componentes del DLQI. Conclusiones: El tratamiento homeopático individualizado se asoció con una mejoría significativa de las puntuaciones en VASI, VETF y DLQI. La premisa de que los efectos observados se deben a placebo se debe aclarar en futuros ensayos clínicos aleatorios doble ciego, precedidos por estudios de viabilidad.

Background: Vitiligo is a common hypopigmentation disorder with significant psychological impact. An evaluation of homeopathic treatment was performed in individuals with vitiligo in a hospital outpatient clinic in West Bengal, India. Methods: 30 participants (median age 27 years old, 57% female) were recruitedfor a prospective open-label pilot study and treated with individualized homeopathic medicines for six months. Efficacy was assessed after three months and six months using Vitiligo Area Scoring Index (VASI) score, Vitiligo European Task Force (VETF)score, and Dermatological Life Quality Index (DLQI) score, which are validatedoutcome measures evaluating the area, intensity, spread of depigmentation ofvitiligo lesions, and quality of life (QoL). Results: A total of 27 participants completed the trial; 3 dropped out. After 6 months of treatment, the median VASI total score improved significantly by 0.1 units (p=0.003), from 0.8 (0.5, 1.5) to 0.7 (0.3, 0.8) on a scale from 0 (no depigmentation) to 100 (completely depigmented). Similarly, the VETF median score improved by 2 units (p=0.0001) from 1 (0, 1) to -1 (-1, 0) and the staging score changed from 1 (1, 2) to 1 (0, 1), p=0.002. The total DLQI median score exhibited significant reduction from 21 (17, 22) to 13.6 (10, 17), change 7.4 (p=0.0001), as also did its components. Conclusions: Individualized homeopathictreatment associated with significant improvement of VASI, VETF and DLQI scores. The extent to which the observed effects were due to placebo needs clarificationin future randomized double-blind clinical studies preceded by feasibility studies.

A survey exploring research perception of homeopathic undergraduate students in West Bengal, India

Background: Prioritizing undergraduate research is emphasized to develop critical analytical skills and thinking, independent writing, future clinical practice, enhanced employability, and improved research productivity. Despite far reaching consequences, research perception of homeopathic undergraduate students has barely been investigated to date. Poor participation of homeopathic undergraduates in research is reflected by a single MEDLINE indexed publication with adequate students’ contribution in the last decade. We aimed to assess their knowledge and attitude towards research and to identify barriers towards successful conduct of research. Methods: Institutional cross-sectional survey was carried out during August-September, 2013 in the four Government undergraduate homeopathic schools in West Bengal, India involving 902 participants. A semi-structured questionnaire was developed for the purpose depending on earlier studies on medical undergraduates. 364 completed responses were analyzed in the end. Results: Study sample mostly spanned 18-25 years of age group (94%), belonged to urban families (44.8%), with no gender differences (almost 1:1) and no physicians in family (73.1%). Maximum complete responses were obtained from 3rd year students (61.5%) and students of Calcutta Homeopathic Medical College and Hospital (51.2%). In spite of willingness to participate and keeping a positive attitude towards research, current involvement, training, knowledge and awareness remained quite unsatisfactory. Lack of infrastructure was identified as the chief barrier towards research. Conclusion: Undergraduates had a positive attitude towards homeopathic research, but need a realistic understanding of the research process. Opportunities for research skill development are underdeveloped.

Introdução: Estimular a pesquisa no nível de graduação é considerado um recurso importante para o desenvolvimento da capacidade de análise e pensamento críticos, redação independente, prática clínica futura, melhorar as possibilidades de inserção no mercado de trabalho e a produtividade em pesquisa. Apesar dessas consequências de amplo alcance, a percepção sobre pesquisa de estudantes de graduação em homeopatia tem sido raramente investigada. A escassa participação em pesquisas de estudantes de graduação em homeopatia é evidenciado pelo achado de um único trabalho indexado em MedLine com expressiva participação de estudantes nos últimos 10 anos. O nosso objetivo consistiu em avaliar o conhecimento e atitude em relação à pesquisa e identificar as barreiras que impedem o sucesso na realização de pesquisas. Métodos: Um estudo transversal foi realizado entre agosto e setembro de 2013 nas quatro faculdades públicas de homeopatia na Bengala Ocidental, Índia, com um total de 902 participantes. Um questionário semiestruturado foi desenvolvido especificamente para este estudo baseado nos resultados de estudos anteriores realizados com estudantes de medicina. Um total de 364 questionários completos foi incluído na análise. Resultados: A maioria dos participantes tinha entre 18 e 25 anos de idade (94%), residia em áreas urbanas (44.8%) e não incluía médicos na família (73,1%). A amostra apresentou homogeneidade em relação ao sexo (quase 1:1). O maior número de questionários completos correspondeu a estudantes do 3o ano (61,5%) e da Faculdade e Hospital Homeopático de Calcutá (51,2%) [...] Conclusão: Os estudantes manifestaram atitude positiva em relação à pesquisa em homeopatia, porém precisam adquirir uma compreensão mais realista do processo de pesquisa. As oportunidades para desenvolvimento de competências de pesquisa são muito escassas.

Understanding of biostatistics among the homeopathic fresh graduates and post-graduate trainees in West Bengal, India

Background: A basic understanding of biostatistics is essential, both for designing quality research and evaluating medical literature. We evaluated the understanding of biostatistics and interpretation of research results among homeopathic fresh graduates’ (House Staffs; HSs) and postgraduate trainees’ (PGTs) in West Bengal, India. Methods: A cross-sectional survey of homeopathic HSs and PGTs in the four government homeopathic schools in West Bengal, India, using a pre-tested, valid and reliable biostatistics multiple choice knowledge, confidence and attitude test questionnaire. Results: Internal consistency of the used questionnaires was acceptable (Cronbach’s á = 0.611 – 0.672). Response rate was only 55.6%. Research journal reading habit was seriously lacking. No one had ever taken any research courses or possessed any advanced degrees or diplomas. The overall mean% correct on statistical knowledge was very poor, 1.0% (95% CI 0.1 – 1.9%) vs. 10.0% (95% CI 8.6 – 11.6%) for HSs and PGTs (P < 0.0001). Comparatively, higher knowledge scores were found in respondents from Mahesh Bhattacharyya Homeopathic Medical College and Hospital (P = 0.003). No one could interpret an unadjusted odds ratio, Kaplan-Meier analysis results, and determine strength of evidence for risk factors. Percentages of correct answers for all other knowledge-based questions ranged between only 2.7 – 9.5%. Respondents’ self-assessed confidence in ability to understand biostatistics ranged between 41 – 60%. Positive attitude towards biostatistics was elicited in 16 – 63% respondents. Conclusions: The respondents seriously lacked knowledge in biostatistics needed to interpret research results. Training programs needs to undergo massive and immediate transformation to include more effective biostatistics training in curricula to encourage meaningful research.

Self-medication tendencies of patients visiting out-patient departments of Government homoeopathic medical colleges and hospitals in West Bengal, India

Self-medication is mostly prevalent in the low- and middle-income population segments of developing countries, thus reflecting the status of health services. Self-medication has frequently been held responsible for inducing drug resistance, higher cost of further treatment, and other complications. The World Health Organization (WHO) promotes self-medication in rural and remote areas to reduce the burden of health services. In this study, the researchers sought to establish the prevalence, consequences, and causes of self-medication. Methods: Multicenter, institution-based, cross-sectional study conducted with 456 participants in May, 2013 at the outpatient clinics of 2 Government homeopathic medical colleges in West Bengal, India. A pilot-tested structured questionnaire consisting of 12 self-administered questions in local vernacular Bengali was used; 8 were close-ended questions providing multiple answer options, while 4 were open-ended. Results: Overall, 12.7% of interviewees admitted to perform self-medication; 57.7% and 66.0% had appropriate knowledge of the medicines and dose regimens, respectively. Females (64.3%) predominated and self-medication was mostly found in age range 31-45 years old (32.5%). Conventional Western medicine (82.2%) was most preferred therapy, and fever (35.7%), hyperacidity (25.4%) and loose stool (24.3%) the most frequently reported complaints. The main causes for self-medication were feeling no need to consult doctor (32.5%), busy schedule (16.4%), family members advice (16.0%), over-the-counter (OTC) availability of medicines without prescription (12.5%), direct consumer pharmaceutical advertisement (12.1%), and high expenditure in private institutes (10.1%). The chi-square distribution of determinants across the two samples differed significantly. The tendency increased proportionately with literacy (Yates’ ÷2=175.731; p=0.000) and poverty (Yates’ ÷2=426.817; p=0.000).

A prevalência da automedicação é mais elevada nos segmentos populacionais de baixa e média renda nos países em desenvolvimento, como reflexo de nível de atenção pública. A automedicação é frequentemente considerada como causa de resistência a medicamentos, aumento do custo do tratamento e outras complicações. Os autores do presente estudo objetivaram investigar a prevalência, consequências e causas da automedicação. Métodos: estudo multicêntrico, institucional e transversal incluindo 456 indivíduos que consultaram em maio de 2013 os ambulatórios de 2 hospitais universitários homeopáticos públicos em Bengala Ocidental, Índia. Foi distribuído para auto-aplicação um questionário estruturado previamente validado num teste piloto. O questionário incluía com 8 perguntas fechadas, com múltiplas opções de resposta, e 4 abertas, na língua vernácula local. Resultados: Aproximadamente 12,7% dos entrevistados admitiram se utilizar de automedicação; 57,7% e 66,0% tinham conhecimento adequado sobre o medicamento utilizado e posologia, respectivamente. A amostra esteve composta predominantemente por mulheres (64,3%), e a faixa etária com maior frequência de automedicação foi a de 31-45 anos (32,5%). A medicina convencional foi indicada como a preferida (82,2%) e as queixas mais frequentes foram febre (35,7%), azia (25,4%) e diarreia (24,3%). As principais causas para a escolha de automedicação foram: sem necessidade de consultar um médico (32,5%), falta de tempo (16,4%), conselho de familiares (16.0%), existência de medicamentos de venda livre (12.5%), publicidade farmacêutica dirigida diretamente ao consumidor (12.1%) e alto custo de serviços de saúde privados (10,1%). O teste de qui quadrado identificou diferença significativa na distribuição dos determinantes entre os dois grupos. A tendência para uso de automedicação aumentou paralelamente ao nível de educação (Yates χ2=175,731; p=0.000) e à pobreza (Yates χ2=426.817; p=0,000).

Homoeopathic treatment of vitiligo: an open observational pilot study

Background: Vitiligo is a common hypopigmentation disorder with significant psychological impact. An evaluation of homeopathic treatment was performed in individuals with vitiligo in a hospital outpatient clinic in West Bengal, India. Methods: Thirty participants (median age 27 years old, 57% female) were recruited for a prospective open-label pilot study and treated with individualized homeopathic medicines for 6 months. Efficacy was assessed after 3 months and 6 months using Vitiligo Area Scoring Index (VASI) score, Vitiligo European Task Force (VETF) score, and Dermatological Life Quality Index (DLQI) score, which are validated outcome measures evaluating the area, intensity, spread of depigmentation of vitiligo lesions, and quality of life (QoL). Results: A total of 27 participants completed the trial; 3 dropped out. After 6 months of treatment, the median VASI total score improved significantly by 0.1 units (p=0.003), from 0.8 (0.5, 1.5) to 0.7 (0.3, 0.8) on a scale from 0 (no depigmentation) to 100 (completely depigmented). Similarly, the VETF median score improved by 2 units (p=0.0001) from 1 (0, 1) to –1 (–1, 0) and the staging score changed from 1 (1, 2) to 1 (0, 1), p=0.002. The total DLQI median score exhibited significant reduction from 21 (17, 22) to 13.6 (10, 17), change 7.4 (p=0.0001), as also did its components. Conclusions: Individualized homeopathic treatment associated with significant improvement of VASI, VETF and DLQI scores. The extent to which the observed effects were due to placebo needs clarification in future randomized double-blind clinical studies preceded by feasibility studies.

Introdução: Vitiligo é uma desordem de hipopigmentação de ocorrência comum, com impacto psicológico significativo. Foi avaliado o tratamento homeopático de indivíduos com vitiligo no ambulatório de um hospital em Bengala Ocidental, Índia. Métodos: Trinta participantes (idade mediana 27 anos, sendo 57% do gênero feminino) foram recrutados para o presente estudo piloto prospectivo aberto e tratados com medicamentos homeopáticos individualizados por 6 meses. A eficácia do tratamento foi avaliada aos 3 e 6 meses mediante Vitiligo Area Scoring Index (VASI) score, Vitiligo European Task Force (VETF), e Dermatological Life Quality Index (DLQI), que são medidas validadas de desfecho correspondendo à área, intensidade e disseminação da depigmentação causada por vitiligo, assim como a qualidade de vida (QV). Resultados: Um total de 27 participantes completou o estudo, sendo que 3 abandonaram. Depois de 6 meses de tratamento, a mediana do escore total do VASI apresentou melhora significativa de 0,1 unidade (p=0,003) passando de 0,8 (0,5, 1,5) para 0,7 (0,3, 0,8), numa escala de 0 (sem depigmentação) a 100 (depigmentação completa). De modo similar, a mediana do escore VETF de disseminação melhorou em 2 unidades (p=0,0001) de 1 (0, 1) a –1 (–1, 0), e o escore de estadiamento variou de 1 (1, 2) para 1 (0, 1), p=0,002. O escore total mediano de DLQI diminuiu de 21 (17, 22) a 13,6 (10, 17), com uma variação de 7,4 (p=0,0001); variação também foi constatada nos componentes de DLQI. Conclusões: O tratamento homeopático individualizado se associou com melhora significativa nos escores de VASI, VETF e DLQI. A parte dos efeitos possivelmente devida a efeito placebo precisa ser determinada em futuros estudos clínicos randomizados e duplo cego, após a realização de estudos de factibilidade.
