Clinical difference between single subtype and mixed subtype chronic urticaria: A retrospective study.

BACKGROUND: The subtypes of chronic urticaria share a common clinical expression, but may show differences phenotypically. Meanwhile, two or more different subtypes of chronic urticaria can coexist in any given patient which may involve different phenotypes. AIMS: The study aims to compare the two phenotypes in terms of demographics, clinical profile and treatment response. METHODS: In this retrospective study, 2678 chronic urticaria patients were divided into the single subtype chronic urticaria group and mixed subtype chronic urticaria group as was appropriate.The differences in the clinical features, possible causes, urticaria activity score of seven days, dermatology life quality index score, laboratory investigations and response to treatments were evaluated among the two groups. RESULTS: An obvious female predominance was detected in chronic urticaria, especially in mixed subtype chronic urticaria patients. Of the 2678 chronic urticaria patients, there were 837(31.25%) mixed subtype chronic urticaria. Chronic spontaneous urticaria combined with symptomatic dermographism was the most common group in the mixed subtype chronic urticaria. Patients with mixed subtype chronic urticaria were more likely to have associated chest tightness/shortness of breath and showed greater urticaria activity. In patients with single subtype chronic urticaria, the positive rate of family history with allergic rhinitis, asthma or urticaria was lower. Based on evaluation of the treatment, control with second-generation antihistamines at licensed doses was achieved in only 38.83% of mixed subtype chronic urticaria patients, compared with 56.32% of patients with single subtype. LIMITATIONS: First, this study was a single-center design retrospective study. Second, omalizumab treatment was not included. Third, the differences between different subtypes of mixed subtype chronic urticaria were not discussed in detail. CONCLUSION: This study showed that mixed subtype chronic urticaria had some distinct features. Comprehensive knowledge about it may help us define effective therapeutic strategies and improve symptom control and the quality of life for chronic urticaria patients.

The unprecedented epidemic-like scenario of dermatophytosis in India: I. Epidemiology, risk factors and clinical features.

Dermatophytosis has attained unprecedented dimensions in recent years in India. Its clinical presentation is now multifarious, often with atypical morphology, severe forms and unusually extensive disease in all age groups. We hesitate to call it an epidemic owing to the lack of population-based prevalence surveys. In this part of the review, we discuss the epidemiology and clinical features of this contemporary problem. While the epidemiology is marked by a stark increase in the number of chronic, relapsing and recurrent cases, the clinical distribution is marked by a disproportionate rise in the number of cases with tinea corporis and cruris, cases presenting with the involvement of extensive areas, and tinea faciei.

Leprosy in the elderly population of an endemic state in the Brazilian Northeast (2001-2017): epidemiological scenario

Abstract This ecological study aims to analyze both the tendency and the characteristics of leprosy in the elderly population in the state of Bahia, 2001-2017. The tendency was analyzed through joinpoint regression. Epidemiological variables were also included in the study. The average detection rate was 38.73/100,000, with prevalence of men (45.19/100,000). A downward trend occurred in both genders, from 2004, with a greater magnitude in women (annual percent change [APC] = −3.4%). Men presented higher proportions of the multibacillary forms and physical disabilities. The epidemiological scenario indicates the need of implementation of actions that stimulate early diagnosis and treatment of the elderly population.

Leprosy: prevalence and factors associated with seropositivity for anti-NDO-LID antibodies in children under 15 years of age.

BACKGROUND: A high prevalence of leprosy among children under 15 years of age indicates the need to implement actions to prevent new cases of the disease. Serological tests have been developed with the aim of helping to control the disease by indicating, through seropositivity, the presence of infection. OBJECTIVE: To analyze the prevalence and factors associated with seropositivity rate for anti-NDO-LID antibodies in children under 15 years of age, contacts of leprosy patients. METHOD: We performed a cross-sectional study with 210 children under 15 years old of age. Of them, 50 were household contacts and 160 were neighborhood contacts living in the municipality of Cuiabá, state of Mato Grosso, in 2016. The data were obtained from interviews and the NDO-LID rapid test during home visits from February to July 2016. For the analysis, we used Poisson regression and prevalence ratio. RESULTS: Seropositivity in contacts was 6.2%. Variables associated with seropositive tests included sex (PR = 1.05; 95% CI: 1.01 - 1.08), race/skin color (PR = 0.95; 95% CI: 0.90 - 0.99), residence area (PR = 1.05; 95% CI: 1.01 - 1.09), and number of people per household (PR = 1.06; 95% CI: 1.02 - 1.08). STUDY LIMITATIONS: The small sample size, besides leading to wide confidence intervals, may have been a limitation for the identification of associated factors. CONCLUSIONS: The prevalence of seropositivity was high. Variables associated with NDO-LID seropositivity included female sex, not to be brown skinned, live in urban areas, and live with five or more people.

Hansen's disease in children under 15 years old in the state of Tocantins, Brazil, 2001-2012: epidemiological patterns and temporal trends. / Hanseníase em menores de 15 anos no estado do Tocantins, Brasil, 2001-2012: padrão epidemiológico e tendência temporal.

INTRODUCTION: Tocantins is the most hyperendemic state for leprosy in Brazil. OBJECTIVE: To describe the epidemiological characteristics and temporal trends of leprosy indicators in children under 15 years old in Tocantins between the years of 2001 and 2012. METHODOLOGY: Data analysis of the Notification of Injury Information System (SINAN). New cases under the age of 15 have been included in the state. The indicators were calculated and the temporal trends were analyzed through the join-point regression. RESULTS: There were 1,225 cases in children, mean age of 10.8 years, and male predominated (52%). The mode of detection by spontaneous demand prevailed (55.8%) and more than 9% had some physical disability. Detection in < 15 years was significantly increased between 2001 and 2008 (anual percent change - APC = 3.8%; confidence interval of 95% - 95%CI 0.1 - 7.6), and showed significant decline between 2008 and 2012 (APC = -9.4%; 95%CI -17.2 - -0.8). There was stability for the detection of grade 2 cases (APC = 4.2%; 95%CI -6.7 - 16.3), proportion of grade 2 cases (APC = 4.1%; 95%CI 6.7 - 16.3), proportion of grade 1 cases (APC = 1.3%; 95%CI -6.2 - 9.3), multibacillary ratio (APC = 2.9%; 95%CI -1.7 - 7.7), and proportion of paucibacillary (APC = 2.9%; 95%CI -1.7 - 7.7). CONCLUSION: Leprosy remains an important public health problem in Tocantins, with active transmission and persistence of transmission foci. The stability of the indicators points out the permanence of the late diagnosis and the repressed demands.

The spatial epidemiology of leprosy in Kenya: A retrospective study.

BACKGROUND: Leprosy elimination defined as a registered prevalence rate of less than 1 case per 10,000 persons was achieved in Kenya at the national level in 1989. However, there are still pockets of leprosy in some counties where late diagnosis and consequent physical disability persist. The epidemiology of leprosy in Kenya for the period 2012 through to 2015 was defined using spatial methods. METHODS: This was a retrospective ecological correlational study that utilized leprosy case based data extracted from the National Leprosy Control Program database. Geographic information system and demographic data were obtained from Kenya National Bureau of Statistics (KNBS). Chi square tests were carried out to check for association between sociodemographic factors and disease indicators. Two Spatial Poisson Conditional Autoregressive (CAR) models were fitted in WinBUGS 1.4 software. The first model included all leprosy cases (new, retreatment, transfers from another health facility) and the second one included only new leprosy cases. These models were used to estimate leprosy relative risks per county as compared to the whole country i.e. the risk of presenting with leprosy given the geographical location. PRINCIPAL FINDINGS: Children aged less than 15 years accounted for 7.5% of all leprosy cases indicating active leprosy transmission in Kenya. The risk of leprosy notification increased by about 5% for every 1 year increase in age, whereas a 1% increase in the proportion of MB cases increased the chances of new leprosy case notification by 4%. When compared to the whole country, counties with the highest risk of leprosy include Kwale (relative risk of 15), Kilifi (RR;8.9) and Homabay (RR;4.1), whereas Turkana had the lowest relative risk of 0.005. CONCLUSION: Leprosy incidence exhibits geographical variation and there is need to institute tailored local control measures in these areas to reduce the burden of disability.

Performance of diagnostic tests for pulmonary tuberculosis in indigenous populations in Brazil: the contribution of Rapid Molecular Testing.

OBJECTIVE: To evaluate the accuracy of rapid molecular testing as a diagnostic tool and estimate the incidence of smear-positive pulmonary tuberculosis among the indigenous population. METHODS: This is an epidemiological study based on secondary data. We calculated the incidence of smear-positive pulmonary tuberculosis between January 1st, 2011 and December 31, 2016, and the performance of bacilloscopy and rapid molecular testing in diagnosing pulmonary tuberculosis compared to sputum culture (standard test). RESULTS: We included 4,048 cases of indigenous people with respiratory symptoms who provided sputum samples for analysis. Among them, 3.7%, 6.7%, and 3.7% had positive results for bacilloscopy, sputum culture, and rapid molecular testing, respectively. The mean incidence of pulmonary tuberculosis was 269.3/100 thousand inhabitants. Rapid molecular testing had 93.1% sensitivity and 98.2% specificity, compared to sputum culture. Bacilloscopy showed 55.1% sensitivity and 99.6% specificity. CONCLUSIONS: Rapid molecular testing can be useful in remote areas with limited resources and a high incidence of tuberculosis, such as indigenous villages in rural regions of Brazil. In addition, the main advantages of rapid molecular testing are its easy handling, fast results, and the possibility of detecting rifampicin resistance. Together, these attributes enable the early start of treatment, contributing to reduce the transmission in communities recognized as vulnerable to infection and disease.

Leprosy in the post-elimination era: a clinico-epidemiological study from a northern Indian tertiary care hospital.

INTRODUCTION: Leprosy is a chronic disease caused by Mycobacterium leprae. Despite being eliminated from India in 2005, there are still a considerable number of leprosy cases. METHODS: A prospective hospital-based study involving all leprosy patients attending the leprosy clinic at the Department of Dermatology from January 2015 to December 2016. RESULTS: A total of 220 patients visited the leprosy clinic during the study period. Most of the patients (48.7%) were 20 to 40 years old. Multibacillary disease was more common in females (84.7%) than males (67.6%), and in rural patients (80.9%) than urban patients (64.8%). Borderline lepromatous leprosy was the most common (38.2%) type of leprosy seen, followed by lepromatous leprosy (28.2%) and borderline tuberculoid leprosy (21.4%). CONCLUSIONS: Despite elimination, leprosy continues to be a health problem in this part of the world. We have shown that females and the rural population are more susceptible to multibacillary disease.

Psoriasis increases the risk of concurrent inflammatory bowel disease: A population-based nationwide study in Korea.

BACKGROUND: The epidemiology of the association between psoriasis and inflammatory bowel disease is poorly defined and remains controversial. AIM: To evaluate the prevalence of inflammatory bowel disease in patients with psoriasis compared with the general population. METHODS: We searched the nationwide health claims database between 2011 and 2015 and evaluated the prevalence of inflammatory bowel disease, including Crohn's disease and ulcerative colitis. RESULTS: Prevalence of inflammatory bowel disease, Crohn's disease and ulcerative colitis in patients with psoriasis vs the general population in 2011 were 0.16, 0.05 and 0.12% vs 0.08, 0.03 and 0.06%, respectively, which increased significantly with time between 2011 and 2015. Patients with psoriasis consistently revealed higher standardized prevalence (age and sex adjusted) of inflammatory bowel disease, Crohn's disease and ulcerative colitis compared with the general population. Subgroup analysis revealed the highest risk of prevalent inflammatory bowel disease in patients younger than 19 years (crude odds ratio 5.33, 95% confidence interval 3.74-7.59). Severe psoriasis demonstrated higher odds of inflammatory bowel disease (odds ratio 2.96, 95% confidence interval 2.54-3.45) than mild psoriasis (odds ratio 1.68, 95% confidence interval 1.51-1.88). LIMITATIONS: Limited data for doing adjustment and cross-sectional study design. CONCLUSIONS: Psoriasis patients revealed higher risk of inflammatory bowel disease. In particular, young patients and those with severe psoriasis may require closer monitoring and comprehensive management.

Linking of psoriasis with osteopenia and osteoporosis: A cross-sectional study.

BACKGROUND/PURPOSE: Psoriasis is a multisystem disease which has been related to vitamin-D deficiency through chronic inflammation. This psoriasis-related inflammatory state and vitamin-D deficiency may induce bone mineral density loss. The purpose of this study is to assess the relationship of psoriasis with bone mineral density, by comparing psoriatic patients with healthy controls and patients with osteopenia/osteoporosis. METHODS: A total of 185 subjects were studied; 58 psoriatic patients who had not been under systemic or biological treatment were included. Age, gender, body mass index, phosphocalcic metabolic parameters and hip and lumbar (L4) bone mineral density data were collected. These variables were compared with those collected in 61 healthy controls and 67 patients with osteopenia/osteoporosis. RESULTS: Psoriatic patients showed worse hip and lumbar spine bone mineral density levels than healthy controls (P = 0.001) and better levels than osteoporotic patients (P < 0.001). Multivariate analysis demonstrated a negative association of age and a positive association of body mass index in hip bone mineral density in psoriatic patients. LIMITATIONS: The main limitations are those of cross-sectional studies, such as a lack of follow up period, and a male predominance in the psoriatic group, which is corrected employing a multivariate analysis with an adjusted model for confounding factors. CONCLUSIONS: Bone mineral density levels in psoriatic patients are situated halfway between healthy controls and patients with osteopenia/osteoporosis. In addition, the higher body mass index in patients with psoriasis appears to confer a protective effect against further development of lower bone mineral density.

RESUMO Objetivo: Avaliar a acurácia do teste rápido molecular como ferramenta diagnóstica e estimar a incidência de casos pulmonares positivos entre a população indígena. Métodos: Estudo epidemiológico baseado em dados secundários. Foi calculada a incidência de casos de tuberculose pulmonar positiva entre 1° de janeiro de 2011 e 31 de dezembro de 2016, e o desempenho da baciloscopia e do teste rápido molecular no diagnóstico de tuberculose pulmonar, em comparação à cultura de escarro (teste padrão). Resultados: Foram incluídos 4.048 casos de indígenas considerados sintomáticos respiratórios, que forneceram amostras de escarro para análise. Destes, 3,7%, 6,7% e 3,7% apresentaram resultados positivos para baciloscopia, cultura e teste rápido molecular, respectivamente. A incidência média de tuberculose pulmonar foi de 269,3/100 mil habitantes. A sensibilidade do teste rápido molecular, em relação à cultura, foi 93,1% e a especificidade foi 98,2%. A baciloscopia apresentou sensibilidade 55,1% e especificidade 99,6%. Conclusões: O teste rápido molecular pode ser útil em áreas remotas, com recursos limitados e incidência de tuberculose elevada, como as aldeias indígenas nas áreas rurais do país. Ademais, o teste rápido molecular apresenta como principais vantagens o fácil manuseio, os resultados rápidos e a possibilidade de identificar a resistência à rifampicina. Em conjunto, esses atributos facilitam o início do tratamento precoce, contribuindo para reduzir a transmissão em comunidades reconhecidamente vulneráveis à infecção e à doença.

Profile of dermatological consultations in Brazil (2018)

Abstract: Background: Dermatological diseases are among the primary causes of the demand for basic health care. Studies on the frequency of dermatoses are important for the proper management of health planning. Objectives: To evaluate the nosological and behavioral profiles of dermatological consultations in Brazil. Methods: The Brazilian Society of Dermatology invited all of its members to complete an online form on patients who sought consultations from March 21-26, 2018. The form contained questions about patient demographics, consultation type according to the patient's funding, the municipality of the consultation, diagnosis, treatments and procedures. Diagnostic and therapeutic decisions were compared between subgroups. Results: Data from 9629 visits were recorded. The most frequent causes for consultation were acne (8.0%), photoaging (7.7%), nonmelanoma skin cancer (5.4%), and actinic keratosis (4.7%). The identified diseases had distinct patterns with regard to gender, skin color, geographic region, type of funding for the consultation, and age group. Concerning the medical conducts, photoprotection was indicated in 44% of consultations, surgical diagnostic procedures were performed in 7.3%, surgical therapeutic procedures were conducted in 19.2%, and cosmetic procedures were performed in 7.1%. Study limitations: Nonrandomized survey, with a sample period of one week. Conclusion: This research allowed us to identify the epidemiological profiles of the demands of outpatients for dermatologists in various contexts. The results also highlight the importance of aesthetic demands in privately funded consultations and the significance of diseases such as acne, nonmelanoma skin cancer, leprosy, and psoriasis to public health.
