Disturbed by a sandfly: visceral leishmaniasis in ileal Crohn´s disease under combined immunosuppression.

This case reports illustrates a 44-year-old Caucasian male with ileal Crohn´s disease under combined immunosuppression that first presented with unspecific constitutional symptoms, newly pancytopenia and elevated inflammatory markers. The infectious screening was negative except for an ileal abscess that resolved with conservative antibiotic therapy. Due to concerns for lymphoproliferative disease in a patient under anti-TNF and azathioprine, a myelogram was performed that ruled out dysplastic changes. After abscess resolution the symptoms relapsed with evening fever, nocturnal sudoresis and worsen pancytopenia. A more thorough work-up was performed with bone marrow and ileal biopsies that demonstrated numerous intra-and-extracellular leishmania amastigote forms, which confirmed the diagnosis of visceral leishmaniasis infiltrating the small bowel. The patient recovered after adequate treatment and withheld of immunosuppression during follow-up.

Metachronous lesions after gastric endoscopic submucosal dissection: first assessment of the FAMISH prediction score.

BACKGROUND: Surveillance after gastric endoscopic submucosal dissection (ESD) is recommended for all patients owing to the persistent risk of metachronous gastric lesions (MGLs). We developed and validated a prediction score to estimate MGL risk after ESD for early neoplastic gastric lesions, to define an individualized and cost-saving approach. METHODS: Clinical predictors and a risk score were derived from meta-analysis data. A retrospective, single-center, cohort study including patients with ≥ 3 years of standardized surveillance after ESD was conducted for score validation. Predictive accuracy of the score by the area under the receiver operating characteristic curve (AUC) was assessed and cumulative probabilities of MGL were estimated. RESULTS: The risk score (0-9 points) included six clinical predictors (scored 0-3): positive family history of gastric cancer, older age, male sex, corpus intestinal metaplasia, synchronous gastric lesions, and persistent Helicobacter pylori infection (FAMISH). The study population included 263 patients. The MGL rate was 16 %. The score diagnostic accuracy for predicting MGL at 3 years' follow-up, measured by the AUC, was 0.704 (95 %CI 0.603-0.806). At 3 years and a cutoff < 2, the score achieved maximal sensitivity and negative predictive value; 15 % of patients could be assigned to a low-risk group, in which the progression to MGL was significantly lower than for the high-risk group (P = 0.04). CONCLUSION: The FAMISH score might be a useful tool to accurately identify patients with low-to-intermediate risk for MGL at 3 years of follow-up who could have surveillance intervals extended to reduce the burden of care.

The Effect of Hyperbaric Oxygen Therapy on Rectal Ulcers after Argon Plasma Coagulation.

Chronic radiation proctitis usually develops 3 months after therapy. Despite the lack of standard guidelines regarding treatment, argon plasma coagulation is often a safe and effective endoscopic therapy. However, rectal ulcers are a common complication after argon plasma coagulation. Nevertheless, most patients are asymptomatic and do not require additional monitoring or treatment. We report a case of an argon plasma coagulation-induced ulcer with relevant symptoms and refractory to medical treatment. The patient was treated with hyperbaric oxygen therapy and had complete resolution of the rectal ulcer. Hyperbaric oxygen therapy has shown efficacy in severe chronic proctitis and radiation-induced rectal ulcers, but no clinical report has ever been published on using hyperbaric oxygen therapy for ulcers after argon plasma coagulation. In this case, hyperbaric oxygen therapy was an effective alternative option and can be considered in patients with refractory argon plasma coagulation-induced rectal ulcers.

A proctite rádica crónica desenvolve-se habitualmente 3 meses após radioterapia. Não obstante a ausência de recomendações em relação ao tratamento desta patologia, a terapêutica endoscópica com árgon-plasma é segura e eficaz. Contudo, as úlceras retais são uma complicação frequente, apesar da maioria dos doentes serem assintomáticos e não requerem vigilância e/ou tratamento. Os autores apresentam um caso clínico de um doente com o diagnóstico de proctite rádica crónica, submetido a terapêutica com árgon-plasma com posterior desenvolvimento de úlcera retal refratária a tratamento médico conservador. O doente foi submetido a oxigenoterapia hiperbárica com resolução completa da úlcera retal. De acordo com a literatura, a oxigenoterapia hiperbárica apresenta eficácia na proctite rádica crónica grave e nas úlceras retais induzidas por radioterapia. Contudo, a utilização da oxigenoterapia hiperbárica nas úlceras retais secundárias a terapêutica com árgon-plasma ainda não foi descrita. Neste caso, a oxigenoterapia hiperbárica foi uma opção terapêutica eficaz, podendo ser considerada nas úlceras retais refratárias secundárias a terapêutica com argon-plasma.

Health-Related Quality of Life in Portuguese Patients with Chronic Hepatitis C.

INTRODUCTION: Chronic hepatitis C virus (HCV) infection impacts multiple health and psychosocial dimensions and encompasses a significant overall burden as it progresses to advanced stages of hepatic disease. AIMS: To evaluate for the first time health-related quality of life (HRQoL) of a subset of Portuguese adult patients with chronic hepatitis C using the Portuguese versions of generic, Short-Form 12 Health Survey (SF-12v2), and disease-specific, Chronic Liver Disease Questionnaire (CLDQ), instruments; to assess psychometric properties of CLDQ, Portuguese version. METHODS: HRQoL was evaluated in Portuguese adult outpatients with chronic hepatitis C attending the Hepatology Clinic at Centro Hospitalar do Porto, using SF-12v2 and CLDQ. This transversal study was conducted between April and October 2015. RESULTS: Eighty outpatients with chronic hepatitis C were enrolled, with mean age 57 years (standard deviation 11), 67.5% male, all Caucasian, 76.3% diagnosed for >10 years, 66.3% with C virus genotype 1, 65.0% with hepatic cirrhosis (94.2% of which Child-Pugh A), and 46.3% under current antiviral treatment. For CLDQ internal consistency, Cronbach's α was 0.88; for construct validity, correlations ranged from 0.36 to 0.80 (p < 0.01). Mean CLDQ scores ranged from 4.25 (Worry) to 5.78 (Abdominal Symptoms). Lower scores were observed for Worry, Fatigue, and Emotional Function domains. Statistically significant differences were found in median values of Worry (CLDQ) and Role Emotional (SF-12) (p < 0.05) for "current antiviral treatment," with higher scores for patients that concluded therapy. CONCLUSION: HRQoL was negatively affected in several domains in Portuguese patients with chronic hepatitis C; oral antiviral treatment correlated with better quality of life, assuring its benefits on this population; the CLDQ Portuguese version revealed adequate psychometric properties, and was useful in assessing quality of life in Portuguese HCV patients.
