INTRODUCTION: Absence of fever is associated with higher mortality in septic patients, but the reason for this is unknown. Immune dysfunction may be a potential link between failure to mount a fever and poor outcomes. The purpose of this study was to evaluate monocyte function and clinical surrogates of immunity (i.e. mortality and acquisition of secondary infections) in febrile and afebrile septic patients. METHODS: Single-center, prospective cohort study of 92 critically ill septic patients...

BACKGROUND: Diagnostic tests are performed in a subset of the population who are at higher risk, resulting in undiagnosed cases among those who do not receive the test. This poses a challenge for estimating the prevalence of the disease in the study population, and also for studying the risk factors for the disease. METHODS: We formulate this problem as a missing data problem because the disease status is unknown for those who do not receive the test. We propose a Bayesian selection model which models the joint distribution of the disease outcome and whether testing was received...

Recent outbreaks of Ebola virus disease and Zika virus disease highlight the need for disseminating accurate predictions of emerging zoonotic viruses to national governments for disease surveillance and response. Although there are published maps for many emerging zoonotic viruses, it is unknown if there is agreement among different models or if they are concordant with national expert opinion. Therefore, we reviewed existing predictions for five high priority emerging zoonotic viruses with national experts in Cameroon to investigate these issues and determine how to make predictions more useful for national policymakers...

A 78-year-old man with chief complaints of cough and lower limb numbness was admitted to our hospital. Serum myeloperoxidase-antineutrophil cytoplasmic antibody titer (MPO-ANCA) was elevated (48.8U/ml), and a diagnosis of microscopic polyangiitis (MPA) was made. After admission, the patient developed a fever and right upper quadrant pain. Ultrasonography and computed tomography revealed an acute cholecystitis of unknown cause, and laparoscopic cholecystectomy was performed. Histopathological examination of the resected gallbladder revealed necrotizing vasculitis along with the infiltration of eosinophils, lymphocytes, and plasma cells around the small arteries in the muscular layer of the gallbladder, which are characteristics of MPA...

A 24-year old woman with a history of Crohn's disease developed bloody diarrhea and multiple abdominal abscesses, daily fever, leukocytosis, and elevated CRP several months after her immunosuppressive therapy with azathioprine was stopped. Recurrent abscess punctures did not detect any pathogenic germs and neither clinical nor serological response was achieved by administration of different antimicrobial therapies. Additionally, new splenic abscesses arose despite ongoing therapy. Under the suspicion of the rare aseptic abscess syndrome, representing an auto-inflammatory, extra-intestinal manifestation of Crohn's disease, the antimicrobial therapy was stopped and an intravenous therapy with prednisolone was initiated...

Background: Histoplasmosis is a fungal infection associated with exposure to bat guano. An outbreak of an unknown severe febrile illness occurred among tunnel workers in the Dominican Republic (DR), and resulted in several deaths. We conducted an investigation to confirm etiology and recommend control measures. Methods: A case was defined as fever and ≥2 symptoms consistent with histoplasmosis in a tunnel worker, July-September, 2015. We interviewed workers and family members, reviewed medical records, tested serum and urine for Histoplasma antigen/antibody, and conducted a cohort study to identify risk factors for histoplasmosis and severe infection (intensive care)...

Postpericardiotomy syndrome (PPS) is a common complication following cardiac surgery. In most cases it develops 2 to 3 weeks after the operation. An inflammatory reaction develops in the pericardium or pleural space with fever, chest pain and dyspnea as typical symptoms. The disease process is usually self-limiting. At present, the etiology is unknown, but an immunological mechanism is suspected as the cause of the disease. The incidence of PPS is essentially dependent on diagnostic criteria, patient group and type of operation...

BACKGROUND: Human parechovirus (HPeV) and human non-polio enterovirus (EV) are important causes of fever without sources (FWS) in young infants. Their prevalence and clinical characteristics are largely unknown in Asian countries. This study was conducted to elucidate the epidemiology and clinical characteristics of HPeV and EV infections in febrile young infants in Japan. METHODS: During February 2010 - August 2015, we obtained 53 stool, 44 throat swab, and 20 cerebrospinal fluid (CSF) samples from 56 infants (<3 months) with FWS at a single hospital...

Lactobacillus species are a commensal flora of the human gastrointestinal and the female genitourinary tract. Lactobacilli especially the rhamnosus species, are common components of commercial probiotics. They are rarely associated with pathology in immunocompetent people, but they have been known to cause dental caries, bacteremia, and endocarditis in patients with suppressed immune function. Cases of Lactobacillus bacteremia have been reported in patients with acute myeloid leukemia, large granular lymphocytic leukemia, and in transplant recipients...

Crimean-Congo hemorrhagic fever virus (CCHFV) is a negative-sense, single stranded RNA virus with a three-segmented genome that belongs to the genus Nairovirus within the family Bunyaviridae. CCHFV uses Hyalomma ticks as a vector to infect humans with a wide range of clinical signs, from asymptomatic to Zika-like syndrome. Despite significant progress in genomic analyses, the influences of viral relationships with different hosts on overall viral fitness, survival, and evading the host's immune systems remain unknown...

Fever of unknown origin, or FUO, is a challenging condition for patients and clinicians. In up to 50% of cases no diagnosis is established. Patient workup begins with comprehensive history, physical examination and laboratory tests. Radionuclide imaging has been a second-line procedure. Gallium-67 citrate, which accumulates in infection, inflammation, and tumor, was for many years, the radionuclide test of choice in the workup of FUO. The 24-72 hours between injection and imaging, relatively high radiation dose to patients, and suboptimal image quality are significant disadvantages; imaging results are variable...

Fevers of unknown origin complicate treatment and prevention of infectious diseases and are a global health burden. We examined risk factors of self-reported fever-categorized as "malarial" and "nonmalarial"-in households adjacent to national parks across the Ugandan Albertine Rift, a biodiversity and emerging infectious disease hotspot. Statistical models fitted to these data suggest that perceived nonmalarial fevers of unknown origin were associated with more frequent direct contact with wildlife and with increased distance from parks where wildlife habitat is limited to small forest fragments...

A 26-year-old female was admitted for fever of unknown origin (FUO), headaches, left ankle edema, and a lower extremity rash consistent with erythema nodosum. She had no respiratory symptoms or family history of autoimmune diseases. A chest X-ray was negative for pneumonia or hilar adenopathy. Extensive autoimmune workup was negative. A chest, abdomen, and pelvis computed tomography scan was unremarkable and laboratory studies revealed no source of infection. On hospital day 5, the patient developed a mild productive cough...

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammation caused by uncontrolled proliferation of activated lymphocytes and histiocytes. Often, HLH is an acquired syndrome. We report a case of a nine month-old-boy presented with hepatosplenomegaly, severe anemia, thrombocytopenia, hypertriglyceridemia and high hyperferritinemia. These clinical features of HLH prompted a wide range of infectious and auto-immune tests to be performed. After an extensive diagnostic workup, he was referred to the immune-hematologic unit for HLH suspicion with an unknown cause...

Balloon-assisted enteroscopy (BAE) is an emerging standard procedure by utilizing distensible balloons to facilitate deep endoscopy. Intestines are known to harbor abundant microflora. Whether balloon distension causes perturbation of blood flow and gut barrier dysfunction, and elicits risk of bacterial translocation remains unknown. Our aims were to 1) conduct a prospective study to gather microbiological and molecular evidence of bacterial translocation by BAE in patients, 2) establish a murine model of colonic balloon distension to investigate tissue hypoxia and intestinal barrier, and 3) assess the effect of short- and long-term hypoxia on epithelial permeability using cell lines...

Disseminated cryptococcosis is infrequent in immunocompetent children. Pulmonary and central nervous system are the commonly involved sites of infection in an immunocompromised host. We report a fatal case of disseminated cryptococcosis in an immunocompetent host presenting as fever of unknown origin with miliary shadows on chest radiograph, mimicking tuberculosis. In countries with the heavy burden of tuberculosis, a high index of suspicion is needed for early diagnosis of its close mimics like disseminated cryptococcosis...

BACKGROUND: More than a decade after the outbreak of human coronaviruses (HCoVs) SARS in Guangdong province and Hong Kong SAR of China in 2002, there is still no reoccurrence, but the evolution and recombination of the coronaviruses in this region are still unknown. Therefore, surveillance on the prevalence and the virus variation of HCoVs circulation in this region is conducted. METHODS: A total of 3298 nasopharyngeal swabs samples were collected from cross-border children (<6 years, crossing border between Southern China and Hong Kong SAR) showing symptoms of respiratory tract infection, such as fever (body temperature > 37...
