SUMMARYWhipple's disease is a rare systemic infectious disorder caused by the bacterium Tropheryma whipplei. We report the case of a 61-year-old male patient who presented to emergency room complaining of asthenia, arthralgia, anorexia, articular complaints intermittent diarrhea, and a 10-kg weight loss in one year. Laboratory tests showed the following results: Hb = 7.5 g/dL, albumin = 2.5 mg/dL, weight = 50.3 kg (BMI 17.4 kg/m 2 ). Upper gastrointestinal endoscopy revealed areas of focal enanthema in the duodenum. An endoscopic biopsy was suggestive of Whipple's disease. Diagnosis was confirmed based on a positive serum polymerase chain reaction. Treatment was initiated with intravenous ceftriaxone followed by oral trimethoprim-sulfamethoxazole. After one year of treatment, the patient was asymptomatic, with Hb = 13.5 g/dL, serum albumin = 5.3 mg/dL, and weight = 70 kg (BMI 24.2 kg/m 2 ). Whipple's disease should be considered a differential diagnosis in patients with prolonged constitutional and/or gastrointestinal symptoms. Appropriate antibiotic treatment improves the quality of life of patients.
AIMTo investigate whether the use of proton pump inhibitors (PPIs) increases the incidence of spontaneous bacterial peritonitis (SBP) in patients with cirrhosis and ascites.METHODSAn historical cohort study was carried out in cirrhotic outpatients with ascites followed in a specialized clinic at a tertiary hospital in Southern Brazil. Patient charts were reviewed to collect information on the variables of interest as the use of PPIs. Primary outcome was defined as development of SBP during the study period. SBP was diagnosed based on ascitic fluid polymorphonuclear cell count ≥ 250 cells/mm³ without evidence of an intra-abdominal, surgically treatable source of infection.RESULTSOf 738 cirrhotic patients, 582 (58.2% male) were enrolled, with mean age of 53.6 ± 12 years. Hepatitis C virus infection (36.2%) and alcohol abuse (25.6%) were the main etiologies of cirrhosis. The presence of ascites was detected in 299 (51.4%) patients during the development of the study. Nineteen patients with previous diagnosis of SBP undergoing secondary prophylaxis and 22 patients with insufficient PPI data were further excluded. Of 258 patients with ascites, 151 used PPIs, and 34 developed SBP (22.5%). Among 107 non-users of PPIs, 23 developed SBP (21.5%) (HR = 1.44, 95%CI: 0.85-2.47, P = 0.176). The median follow-up time of patients using PPI was 27 mo vs 32 mo for non-users. Univariate analysis of the risk factors associated with the development of SBP revealed a significant association of SPB with the severity of liver disease according to the Child-Turcotte-Pugh (CTP) score. Multivariate analysis confirmed that CTP score was the only independent variable influencing the occurrence of SBP. Survival at 60 mo (Kaplan-Meier analysis) was similar in users and non-users of PPI, independently of the presence of SBP (58.4% vs 62.7% respectively, P = 0.66). For patients with SBP, survival at 60 mo was 55.1%, vs 61.7% in patients without SBP (P = 0.34).CONCLUSIONIn conclusion, the rate of SBP was not significantly different in users or non-users of PPIs in this cohort of cirrhotic with ascites.
Probiotics are commonly prescribed as an adjuvant in the treatment of antibiotic-associated diarrhea caused by Clostridium difficile. We report the case of an immunocompromised 73-year-old patient on chemotherapy who developed Saccharomyces cerevisiae var. boulardii fungemia in a central venous catheter during treatment of antibiotic-associated pseudomembranous colitis with the probiotic Saccharomyces cerevisiae var. boulardii. Fungemia was resolved after interruption of probiotic administration without the need to replace the central venous line.
SUMMARYChromoblastomycosis is a chronic human melanized fungi infection of the subcutaneous tissue caused by traumatic inoculation of a specific group of dematiaceous fungi through the skin, often found in barefooted agricultural workers, in tropical and subtropical climate countries. We report the case of a male patient presenting a slow-growing pruriginous lesion on the limbs for 20 years, mistreated over that time, which was diagnosed and successfully treated as chromoblastomycosis. Besides the prevalence of this disease, treatment is still a clinical challenge.
Turner syndrome is an exclusively female genetic disease caused by complete or partial absence of the second X chromosome. It is classically characterized by congenital lymphedema, short stature, and gonadal dysgenesis. In addition, the syndrome is associated with several other abnormalities. One of them is gastrointestinal bleeding, which is frequently associated with inflammatory bowel disease, but it can also be caused by vascular lesions such as hemangioma, vascular ectasia, and telangiectasia. We report the case of a patient with Turner syndrome with an episode of gastrointestinal bleeding, outlining our pathway for the investigation and treatment of this condition.
AIMTo determine the incidence of hepatocellular carcinoma (HCC) and the impact of HCC surveillance on early diagnosis and survival of cirrhotic outpatients.METHODSIn this retrospective cohort study, cirrhotic outpatients undergoing HCC surveillance between March 2005 and March 2014 were analyzed. Exclusion criteria were HIV coinfection; previous organ transplantation; diagnosis of HCC at first consultation; missing data in the medical chart; and less than 1 year of follow-up. Surveillance was carried out every six months using ultrasound and serum alpha-fetoprotein determination. Ten-year cumulative incidence and survival were estimated through Kaplan-Meier analysis.RESULTSFour hundred and fifty-three patients were enrolled, of which 57.6% were male. Mean age was 55 years. Hepatitis C virus and heavy use of alcohol were the main etiologic agents of cirrhosis. HCC was diagnosed in 75 patients (16.6%), with an estimated cumulative incidence of 2.6% in the 1st year, 15.4% in the 5th year, and 28.8% in the 10th year. Median survival was estimated at 17.6 mo in HCC patients compared to 234 mo in non-HCC patients (P < 0.001). Early-stage HCC was more often detected in patients who underwent surveillance every 6 mo or less (P = 0.05). However, survival was not different between patients with early stage vs non-early stage tumors [HR = 0.54 (0.15-1.89), P = 0.33].CONCLUSIONHCC is a frequent complication in patients with cirrhosis and adherence to surveillance programs favors early diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
