BACKGROUND: Sapovirus is a common cause of self-limiting diarrhea. In immunocompromised individuals chronic infections occur, but are incompletely investigated. OBJECTIVES: To investigate viral evolution in immunocompromised hosts during chronic sapovirus infection. STUDY DESIGN: From January 2010 to September 2018 stool samples of 5333 in-patients were analyzed for the presence of sapovirus RNA by real-time RT-PCR. In follow-up samples of chronic diarrhea cases nucleic acid sequencing of sapovirus genomes was performed...

An 85-year-old woman hospitalized for rehabilitation after cerebral infarction developed persistent bloody diarrhea and was transferred to our hospital (day 1). Contrast-enhanced computed tomography of the abdomen showed edematous thickening extending from the left side of the transverse colon to the rectum, with decreased mucosal enhancement. She was diagnosed with ischemic enteritis. She fasted and was treated with fluids and antibiotics. The bloody diarrhea stopped, and she was restarted on the direct oral anticoagulant (DOAC) edoxaban on day 5...

Cryptosporidiosis is one of the leading causes of moderate to severe diarrhea in children in low-resource settings. The therapeutic options for cryptosporidiosis are limited to one drug, nitazoxanide, which unfortunately has poor activity in the most needy populations of malnourished children and HIV infected persons. This paper describes the discovery and early optimization of a class of imidazopyridine-containing compounds with potential for treating Cryptosporidium infections. The compounds target the Cryptosporidium methionyl-tRNA synthetase (MetRS), an enzyme that is essential for protein synthesis...

BACKGROUND: Previous research suggests an age differential in health-related quality of life (HRQOL) among long-term (5-10 years post-diagnosis, LTS) colorectal cancer (CRC) survivors. Few studies have specifically addressed the association of age differentials with HRQOL for very long-term CRC survivors (>10 years post-diagnosis, VLTS) and non-cancer population controls. We aimed to assess possible deficits in HRQOL of disease-free CRC-LTS and CRC-VLTS in comparison with non-cancer population controls, and whether the observed pattern varies by age and time since diagnosis...

We investigated the potential for viremic sera from cattle persistently infected with bovine viral diarrhea virus to create false-negative antibody results when testing pools of 10 sera by indirect or blocking ELISAs. Seronegative viremic sera ( n = 23) were each added to a series of artificially constructed pools containing various percentages (0-90%) of antibody-positive sera, and the resulting pools were assayed for antibody. In all 23 cases, a negative antibody result was obtained in the pool containing no seropositive sera...

Shigella is one of the major enteric pathogens worldwide. We present a murine model of S. flexneri infection and investigate the role of zinc deficiency (ZD). C57BL/6 mice fed either standard chow (HC) or ZD diets were pretreated with an antibiotic cocktail and received S. flexneri strain 2457T orally. Antibiotic pre-treated ZD mice showed higher S. flexneri colonization than non-treated mice. ZD mice showed persistent colonization for at least 50 days post-infection (pi). S. flexneri-infected mice showed significant weight loss, diarrhea and increased levels of fecal MPO and LCN in both HC and ZD fed mice...

BACKGROUND: Clostridium difficile (C. difficile) infection is an important cause of healthcare-associated diarrhea. Several factors such as admission of colonized patients, levels of serum antibodies in patients, and control strategies may involve in determining the prevalence and the persistence of C. difficile in a hospital unit. METHODS: We develop mathematical models based on deterministic and stochastic frameworks to investigate the effects of control strategies for colonized and symptomatic patients and admissions of colonized and symptomatic patients on the prevalence and the persistence of C...

BACKGROUND: There is an increasing recognition that children remain at elevated risk of death following discharge from health facilities in resource-poor settings. Diarrhea has previously been highlighted as a risk factor for post-discharge mortality. METHODS: A retrospective cohort study was conducted to estimate the incidence and demographic, clinical, and biochemical features associated with inpatient and 1-year post-discharge mortality amongst children aged 2-59 months admitted with diarrhea from 2007 to 2015 at Kilifi County Hospital and who were residents of Kilifi Health and Demographic Surveillance System (KHDSS)...

BACKGROUND Olmesartan, an angiotensin receptor blockade class of antihypertensive medication has recently been associated with a seronegative sprue like enteropathy. Patients typically present with diarrhea and weight loss often prompting exhaustive diagnostic workup. Discontinuation of the drug leads to dramatic recovery and hence, physicians need to be aware of olmesartan associated enteropathy (OAE) in order to avoid unnecessary testing. CASE REPORT A 59-year-old Caucasian male was admitted to the hospital with complaints of intractable diarrhea, vomiting and considerable weight loss...

BACKGROUND: Over half a million children die each year of diarrheal illness, although nearly all deaths could be prevented with oral rehydration salts (ORS). The literature on ORS documents both impressive health benefits and persistent underuse. At the same time, little is known about why ORS is underused and what can be done to increase use. We hypothesized that price and inconvenience are important barriers to ORS use and tested whether eliminating financial and access constraints increases ORS coverage...

BACKGROUND: Patients with neuroendocrine tumors (NETs) and carcinoid syndrome experience considerable morbidity and mortality; carcinoid syndrome may be associated with shorter survival. Carcinoid syndrome is linked to tumoral secretion of serotonin and other bioactive substances. The subsequent debilitating diarrhea and urgency to defecate pose significant health risks. In previous studies, telotristat ethyl, a tryptophan hydroxylase inhibitor, was effective and well tolerated in treating carcinoid syndrome diarrhea...

In the course of the years 1983-1989, 5511 foreigners in the age of 20 to 40 years old from 87 countries were examined for human parasites. Everyone was examined within 1 months of arrival in the Czech Republic in the Active Case Detection (ACD) program. The intensity of infection was measured in those parasites which do not reproduce in the human body. Intensity of infection with geohelmints was express as a number of eggs per gram of feaces (EPG). 1079 foreigners infected with Trichuris trichiura are in 94,8 % suffering of light infection, the cohort of 694 foreigners infected with Ascaris lumbricoides suffered in 49,8 % of light infection, and 349 individuals infected with hookworms suffer in 96,0 % of cases of light infection...

Dermatitis might occur in mucosal disease (MD) caused by bovine viral diarrhea virus (BVDV). This study describes the pathological and virological features of skin lesions associated with BVDV infection in four persistently infected (PI) cattle. Skin samples were reprocessed for histopathology and IHC. BVDV isolates were obtained and were genetically characterized. In addition to upper alimentary system ulcerative lesions, all cattle (one outbreak and three individual cases) presented focal crusty and ulcerative lesions affecting the mucocutaneous and skin-horn junctions, interdigital clefts, pastern, and areas surrounding the dewclaws and diffuse thickened skin within 7-20 days of infection...
