Epidemiological and clinical study of cases of endemic pemphigus foliaceus and pemphigus vulgaris in a reference center in the state of Minas Gerais, Brazil

Abstract Background: Pemphigus constitutes a group of autoimmune bullous diseases. A reduction in the incidence of endemic pemphigus foliaceus and an increase in pemphigus vulgaris has been described, but there are no studies in Minas Gerais that address the subject. Objective: To describe the epidemiological and clinical profile of patients with pemphigus treated at the Dermatology Service of a public University Hospital in the state of Minas Gerais, Brazil. Methods: An observational, descriptive, and cross-sectional study was carried out of cases of endemic pemphigus foliaceus and pemphigus vulgaris, for a period of six months. A questionnaire was filled out with epidemiological and clinical data on the disease. Results: A total of 122 patients were included in the study, 64 with endemic pemphigus foliaceus and 58 with pemphigus vulgaris. When comparing patients with endemic pemphigus foliaceus and those with pemphigus vulgaris, a statistical difference was observed between the median age of initial disease manifestation (p = 0.001), patient occupation (p = 0.010), area of residence (p = 0.000), forests (p = 0.000) and rivers/streams close to the dwelling (p = 0.001) and the number of systemic medications required to control the disease (p = 0.002). When comparing patients with endemic pemphigus foliaceus to those evaluated in a study carried out at the same service in 2008, there was a statistical difference in the area of residence (p = 0.030). Study limitations: The assessed population comes from a tertiary care service that is not a reference for the entire state. Conclusions: Patients with endemic pemphigus foliaceus and pemphigus vulgaris maintain statistically significant differences regarding their main variables in the literature, such as age and area of residence. Historically, there has been a reduction in cases of endemic pemphigus foliaceus and an increase in cases of pemphigus vulgaris in this population.

Acute cellulitis with Shewanella algae bacteremia

ABSTRACT Shewanella algae are gram-negative bacteria commonly found in aquatic environments. Infections caused by this agent are rarely documented; however, they are increasingly reported, mainly in countries with warm to temperate climates. Herein, we present a case of a 46-year-old immunocompetent woman with acute cellulitis and S. algae bacteremia (the first isolation culture performed at our hospital). To better understand the epidemiology, clinical outcomes, and treatment possibilities for S. algae bacteremia, we searched literature for similar cases; however, we did not find any cases of infections caused by this microorganism reported in Portugal or the Azores.

Depression rather than liver impairment reduces quality of life in patients with hepatitis C

Objective: Patients with chronic hepatitis C (CHC) have a poorer quality of life than those with other chronic liver diseases. However, some of the factors that determine health-related quality of life (HRQOL) in these patients, such as the degree of liver fibrosis, are still controversial. Therefore, the aim of the present study was to investigate the impact of CHC on HRQOL by conducting clinical, psychiatric, and sociodemographic evaluations. Methods: One hundred and twenty-four consecutive patients attending a referral center for hepatitis were evaluated using the Mini-International Neuropsychiatry Interview, the Hamilton Depression Rating Scale, the Hospital Anxiety and Depression Scale, and the Medical Outcomes Study 36-Item Short-Form Health Survey. Multiple linear regression analyses were used to quantify independent associations between HRQOL and the clinical, psychiatric, and sociodemographic variables of interest. Results: Reduced HRQOL was independently associated with major depressive disorder (MDD) and with elevated levels of alanine aminotransferase, but was not associated with hepatic cirrhosis. Conclusions: MDD rather than the grade of liver fibrosis was strongly associated with HRQOL impairment in patients with CHC. These findings highlight that, in patients with CHC, the psychological effects of the disease deserve more attention and the implementation of integrated medical, psychiatric, and psychological care may be helpful. .

Atividade física e hepatite C crônica / Physical activity and chronic hepatitis C

A hepatite crônica causada pelo vírus C (VHC) constitui problema relevante de saúde pública no mundo. A infecção associada a esse vírus é considerada causa significativa de cirrose e respectivas complicações: hipertensão portal, descompensação da função hepática e carcinoma hepatocelular. A atividade física é amplamente incentivada no tratamento de diversas doenças crônicas. Entretanto, pouco tem sido pesquisado sobre o efeito da atividade física no curso evolutivo da hepatopatia associada ao VHC. Ainda, sabe-se que indivíduos com hepatite C crônica podem desenvolver outras afecções devido à inatividade física que podem interferir no curso da doença viral. Portanto, o objetivo do presente estudo foi realizar revisão bibliográfica sobre a relação entre atividade física e hepatite C crônica.

Chronic hepatitis caused by hepatitis C virus (HCV) is relevant for the public health problem in the world. The infection associated with this virus is considered a significant cause of cirrhosis and its complications: portal hypertension, decompensation of the liver function and hepatocellular carcinoma. Physical activity is widely encouraged in the treatment of various chronic diseases. However, little has been done on the effect of physical activity on the evolutionary course of the HCV-related liver disease. It is known that individuals with chronic hepatitis C may develop other disorders due to physical inactivity that may interfere in the course of the viral disease. Therefore, the objective of the present study was to conduct a literature review on the relationship between physical activity and chronic hepatitis C.
