[A case of recurrent Campylobacter fetus meningitis, occurring two months after the |initial infection was successfully treated].

A 43-year-old man was admitted to our department due to fever and headache. The cerebrospinal fluid analysis confirmed bacterial meningitis. Campylobacter species were isolated from blood cultures on the third day of admission. The patient was treated with meropenem (MEPM) and discharged on the 17th day. However, he experienced a recurrence of meningitis and was readmitted on the 68th day, initiating MEPM therapy. Campylobacter fetus was isolated from cerebrospinal fluid cultures on the 74th day. MEPM was continued until the 81st day, followed by one month of minocycline (MINO) therapy. The patient had an uneventful recovery without further recurrence. This case highlights the potential for recurrence of Campylobacter fetus meningitis approximately two months after the resolution of the initial infection. In addition to carbapenem therapy for at least two weeks, the adjunctive administration of MINO may be beneficial.

Menthol Pretreatment Alleviates Campylobacter jejuni-Induced Enterocolitis in Human Gut Microbiota-Associated IL-10-/- Mice.

Human Campylobacter jejuni infections are of worldwide importance and represent the most commonly reported bacterial enteritis cases in middle- and high-income countries. Since antibiotics are usually not indicated and the severity of campylobacteriosis is directly linked to the risk of developing post-infectious complications, non-toxic antibiotic-independent treatment approaches are highly desirable. Given its health-promoting properties, including anti-microbial and anti-inflammatory activities, we tested the disease-alleviating effects of oral menthol in murine campylobacteriosis. Therefore, human gut microbiota-associated IL-10-/- mice were orally subjected to synthetic menthol starting a week before C. jejuni infection and followed up until day 6 post-infection. Whereas menthol pretreatment did not improve campylobacteriosis symptoms, it resulted in reduced colonic C. jejuni numbers and alleviated both macroscopic and microscopic aspects of C. jejuni infection in pretreated mice vs. controls. Menthol pretreatment dampened the recruitment of macrophages, monocytes, and T lymphocytes to colonic sites of infection, which was accompanied by mitigated intestinal nitric oxide secretion. Furthermore, menthol pretreatment had only marginal effects on the human fecal gut microbiota composition during the C. jejuni infection. In conclusion, the results of this preclinical placebo-controlled intervention study provide evidence that menthol application constitutes a promising way to tackle acute campylobacteriosis, thereby reducing the risk for post-infectious complications.

Campylobacter Infection-Associated Acute Pancreatitis in a Renal Transplant Recipient.

Immunocompromised individuals (patients with cancer, diabetes, HIV/AIDS, transplant recipients) and pregnant women are at greater risk of complicated foodborne illness than the general population. Though rare, Campylobacter enteritis-associated acute pancreatitis has not been reported in an immunocompromised host to our knowledge. Herein, we describe a case of Campylobacter infection-associated pancreatitis in a renal transplant recipient. This case highlights the need for food safety education for the immunocompromised, emphasizes the role of health care providers in encouraging adherence to food safety guidelines, and stresses the need to maintain broad infectious differentials for immunocompromised patient populations, even for conditions which are not commonly associated with an infectious etiology.

Clinical Features, Immunological Characteristics, and Treatment Outcomes of Campylobacter spp. Infections in Patients With Common Variable Immunodeficiency.

BACKGROUND: Campylobacter infection usually causes a self-limited clinical illness lasting 5 to 7 days, resolving without antimicrobial treatment in immunocompetent subjects. However, an inadequate immune response can lead to a prolonged and severe disease requiring antibiotics and more aggressive therapeutic approaches. OBJECTIVE: To comprehensively describe Campylobacter spp. infections in patients with common variable immunodeficiency (CVID). METHODS: A retrospective cohort of 14 CVID patients with Campylobacter infection and 95 CVID controls attending the immunology clinic at a large tertiary hospital was assessed. Immunological, clinical, and microbiological parameters were measured with median follow-up over 20 years in both cohorts. Patients were treated according to a novel algorithm for Campylobacter in antibody-deficient patients. RESULTS: Campylobacter patients had a higher proportion of CD21lowCD38low and transitional B cells (median 38.0% vs 14.2% and 5.4% vs 3.2%) and lower long-term average CD19+ B cells (median 0.06 vs 0.18 × 109/L) and CD4+ T cells (0.41 vs 0.62 × 109/L) in comparison with the controls. Similarly, Campylobacter patients showed a decline in B cells (median 0.02 vs 0.14 × 109/L), CD4+ T cells (0.33 vs 0.59 × 109/L), CD8+ T cells (0.26 vs 0.62 × 109/L), and natural killer cells (0.08 vs 0.18 × 109/L) over time. Antimicrobial resistance, especially to macrolides and fluoroquinolones, was common. Bacterial clearance with associated clinical improvement was obtained after a median of 20 and 113 days for acute Campylobacter (resolution within 3 mo of onset) and chronic Campylobacter (>3 mo) infections, respectively. Seven received first-line treatment (azithromycin or chloramphenicol), 4 second-line (neomycin), and 3 third-line (combination of tigecycline, chloramphenicol, and ertapenem; 1 received gentamicin owing to resistance to carbapenems). CONCLUSIONS: Our study highlights immunological and clinical characteristics of recurrent Campylobacter infections in patients with CVID. Our treatment algorithm was successful and should be evaluated in a larger cohort.

Oncogenic potential of Campylobacter infection in the gastrointestinal tract: narrative review.

BACKGROUND: Campylobacter jejuni is the leading cause of zoonotic gastroenteritis. The other emerging group of Campylobacters spp. are part of human oral commensal, represented by C. concisus (CC), which has been recently linked to non-oral conditions. Although long-term gastrointestinal (GI) complications from these two groups of Campylobacters have been previously reviewed individually, overall impact of Campylobacter infection on GI carcinogenesis and their inflammatory precursor lesions has not been assessed collectively. AIMS: To evaluate the available evidence concerning the association between Campylobacter infection/colonization and inflammatory bowel disease (IBD), reflux esophagitis/metaplasia colorectal cancer (CRC) and esophageal cancer (EC). METHODS: We performed a comprehensive literature search of PubMed for relevant original publications and systematic reviews/meta-analyses of epidemiological and clinical studies. In addition, we gathered additional information concerning microbiological data, animal models and mechanistic data from in vitro studies. RESULTS: Both retrospective and prospective studies on IBD showed relatively consistent increased risk associated with Campylobacter infection. Despite lack of supporting prospective studies, retrospective studies based on tissue/fecal microbiome revealed consistent enrichment of Campylobacter in CRC samples. Studies on EC precursor lesions (esophagitis and metaplasia) were generally supportive for the association with Campylobacter, while inconsistent observations on EC. Studies on both IBD and EC precursors suggested the predominant role of CC, but studies on CRC were not informative of species. CONCLUSIONS: There is sufficient evidence calling for concerted effort in unveiling direct and indirect connection of this organism to colorectal and esophageal cancer in humans.

Campylobacter myocarditis: a rare but potential sequelae of Campylobacter jejuni.

Myocarditis is an inflammatory cardiomyopathy with a diverse range of both infective and non-infective causes. It is an important cause of dilated cardiomyopathy worldwide, with a variable clinical course ranging from a mild self-limiting illness to fulminant cardiogenic shock requiring mechanical circulatory support and cardiac transplantation. Here, we describe a case of acute myocarditis secondary to Campylobacter jejuni infection in a man in his 50s who presented with an acute coronary syndrome following a recent gastrointestinal illness.

Development of Meropenem Resistance in a Multidrug-Resistant Campylobacter coli Strain Causing Recurrent Bacteremia in a Hematological Malignancy Patient.

Campylobacter bacteremia is an uncommon disease that mainly occurs in immunocompromised patients and is associated with antibiotic resistance, particularly in Campylobacter coli. We report a patient with persistent blood infection because of a multidrug-resistant (MDR) C. coli strain over a 3-month period. Through this period monotherapy with meropenem was associated with the development of resistance to it. Improving immunity status and a combined therapy for intestinal decolonization were useful to control persistent C. coli infection in this patient.

Pericarditis due to Campylobacter coli infection: a case report.

Campylobacter spp. is a gram-negative bacillus that causes infectious enteritis and consists of several species, including Campylobacter jejuni, Campylobacter coli, and Campylobacter fetus. Although C. jejuni and C. coli cause infectious enteritis primarily in immunocompetent hosts, C. fetus causes extraintestinal infections such as septicemia, meningitis, and perinatal infections in immunocompromised hosts, as well as myopericarditis in rare cases. Only a few cases of infectious myo(peri)carditis associated with C. coli in immunocompetent hosts have been reported. These studies concentrated on antecedent C. coli enterocolitis and never demonstrated a positive culture in the pericardial fluid.A 72-year-old Japanese man presented with a 2-week fever, cough, and vomiting lasting. He was on hemodialysis for polycystic kidney disease, as well as medication for diabetes and hypertension. A chest computed tomography (CT) scan and a transthoracic echocardiogram revealed bilateral pleural fluid and large pericardial fluid at the time of admission. C. coli was identified from blood culture samples and blood-tinged pericardial fluid. He was successfully treated with antibacterial chemotherapy as well as pericardial fluid drainage and was discharged from the hospital with no complications.In this case, the presence of C. coli in the pericardial fluid confirmed the diagnosis of C. coli pericarditis. C. coli may cause septic pericarditis in immunocompromised hosts, despite typically causing only enteritis.

Intestinal Barrier in Post-Campylobacter jejuni Irritable Bowel Syndrome.

BACKGROUND: Campylobacter jejuni (C. jejuni) is one of the most common causes of bacterial gastroenteritis worldwide. One sequela of this infection is the development of post-infectious irritable bowel syndrome (PI-IBS). It has been suggested that a dysfunctional intestinal barrier may promote IBS development. We aimed to test this hypothesis against the background of the leaky gut concept for low-grade inflammation in PI-IBS. METHODS: We identified patients with persistent PI-IBS symptoms after C. jejuni infection. During sigmoidoscopy, forceps biopsies were obtained for electrophysiological measurements of epithelial transport and barrier function in miniaturized Ussing devices. C. jejuni absence was checked by PCR and cytokine production with immunohistochemistry. RESULTS: In PI-IBS, the epithelial resistance of the colon epithelium was unaltered, reflecting an intact paracellular pathway. In contrast, temperature-dependent horseradish peroxidase (HRP, 44 kDa) permeation increased. Short-circuit current (Isc) reflecting active anion secretion and ENaC-dependent electrogenic sodium absorption was unaffected. Early endosome antigen-1 (EEA1) and IL-4 levels increased. C. jejuni is not incorporated into the resident microbiota of the colon mucosa in PI-IBS. CONCLUSIONS: In PI-IBS after C. jejuni infection, macromolecule uptake via endocytosis was enhanced, leading to low-grade inflammation with pro-inflammatory cytokine release. The findings will allow C. jejuni-induced pathomechanisms to be targeted during infection and, thereafter to reduce sequelae such as PI-IBS.

Clinical manifestations and risk factors of campylobacter gastroenteritis in children in Taiwan.

BACKGROUND: Campylobacteriosis is a common cause of bacterial gastroenteritis worldwide. This study aimed to investigate the potential risk factors, clinical and laboratory manifestations of children with campylobacteriosis under five years old in Taiwan. METHODS: This retrospective case-control study was conducted in ten major hospitals in Taiwan from 2014 to 2017. Laboratory tests and stool specimen were collected and analyzed together with questionnaire survey. Multivariate stepwise logistic regression model was used for identification of risk factors. RESULTS: A total of 64 campylobacteriosis cases were included with a median age of 25 months. We observed a less prolonged vomiting (p = 0.047), more bloody (p < 0.001) and mucoid (p = 0.005) stools, and lower AST levels (p = 0.020) in patients with campylobacteriosis. Lower parental educational attainment (p < 0.001), direct contact with acute gastroenteritis patients (p < 0.001), as well as diarrhea in the mutually cared children (p = 0.007) were linked to campylobacteriosis. Consumption of municipal water (p < 0.001), milk (OR 0.34, 95% CI 0.118-0.979), and soft beverages (OR 0.41, 95% CI 0.192-0.888) were identified as protective factors, while consuming takeout food (p = 0.032) and seafood (p = 0.019) increased risk of campylobacteriosis. CONCLUSIONS: Shorter vomiting duration, bloody and mucoid stool, and less elevated AST levels are manifestations suggestive of campylobacteriosis. Risk factors of campylobacteriosis were low parental educational attainment, direct contact with acute gastroenteritis patients, diarrhea in mutually cared children, takeout food and seafood intake. Potential protective factors include municipal water, milk, and soft beverage intake.

Recurrent Guillain-Barré Syndrome Associated with the Second Episode of Campylobacter jejuni Infection.

Guillain-Barré syndrome (GBS) cases are generally monophasic, and recurrence is rare. However, the pathogenesis and pathophysiology of recurrent GBS remain to be fully elucidated. There are few detailed reports of patients who have been infected twice with Campylobacter jejuni and have developed GBS twice. We herein report a case of recurrent GBS in a 21-year-old man with a history of GBS caused by C. jejuni infection at 19 years old. Although our patient was reinfected with C. jejuni, several different anti-ganglioside antibodies were identified, and the clinical manifestations were more severe than those in the first GBS episode. We compared the anti-ganglioside antibodies and nerve conduction studies findings between the two GBS episodes. This case suggested that different antibodies are involved and produce different symptoms even when C. jejuni infection is the trigger in recurrent episodes.

Campylobacter jejuni and Postinfectious Autoimmune Diseases: A Proof of Concept in Glycobiology.

Glycans, one of the most diverse groups of macromolecules, are ubiquitous constituents of all cells and have many critical functions, including the interaction between microbes and their hosts. One of the best model organisms to study the host-pathogen interaction, the gastrointestinal pathogen Campylobacter jejuni dedicates extensive resources to glycosylation and exhibits a diverse array of surface sugar-coated displays. The first bacterium where N-linked glycosylation was described, C. jejuni can additionally modify proteins by O-linked glycosylation, has extracellular capsular polysaccharides that are important for virulence and represent the major determinant of the Penner serotyping scheme, and has outer membrane lipooligosaccharides that participate in processes such as colonization, survival, inflammation, and immune evasion. In addition to causing gastrointestinal disease and extraintestinal infections, C. jejuni was also linked to postinfectious autoimmune neuropathies, of which Guillain-Barré syndrome (GBS) and Miller Fisher syndrome (MFS) are the most extensively characterized ones. These postinfectious autoimmune neuropathies occur when specific bacterial surface lipooligosaccharides mimic gangliosides in the host nervous system. C. jejuni provided the first proof of concept for the involvement of molecular mimicry in the pathogenesis of an autoimmune disease and, also, for the ability of a bacterial polymorphism to shape the clinical presentation of the postinfectious autoimmune neuropathy. The scientific journey that culminated with elucidating the mechanistic details of the C. jejuni-GBS link was the result of contributions from several fields, including microbiology, structural biology, glycobiology, genetics, and immunology and provides an inspiring and important example to interrogate other instances of molecular mimicry and their involvement in autoimmune disease.

[Campylobacter: a vintage pathogen to the fore].

Campylobacteriosis is caused by Gram bacteria. Most common species are C. jejuni and C. coli. Campylobacteriosis is a rare cause of sepsis, and in some European countries it is more common than salmonellosis, becoming a public health problem. We have treated a 66-year-old patient, hypertensive, ischemic cardiopathic, scheduled for coronary angiography, hospitalized with AKI, in a state of shock after some days of acute diarrhea. Because of the pathogen's seasonal nature and the patient's clinical features, in addition to common coproculture also Campylobacter has been sought, and found. Treated with volume repletion and antibiotics, within one week normal kidney functions were fully restored. He had a coronary angiography a week after being discharged from the hospital.

An International Perspective on Preceding Infections in Guillain-Barré Syndrome: The IGOS-1000 Cohort.

BACKGROUND AND OBJECTIVES: Infections play a key role in the development of Guillain-Barré syndrome (GBS) and have been associated with specific clinical features and disease severity. The clinical variation of GBS across geographical regions has been suggested to be related to differences in the distribution of preceding infections, but this has not been studied on a large scale. METHODS: We analyzed the first 1,000 patients included in the International GBS Outcome Study with available biosamples (n = 768) for the presence of a recent infection with Campylobacter jejuni, hepatitis E virus, Mycoplasma pneumoniae, cytomegalovirus, and Epstein-Barr virus. RESULTS: Serologic evidence of a recent infection with C. jejuni was found in 228 (30%), M. pneumoniae in 77 (10%), hepatitis E virus in 23 (3%), cytomegalovirus in 30 (4%), and Epstein-Barr virus in 7 (1%) patients. Evidence of more than 1 recent infection was found in 49 (6%) of these patients. Symptoms of antecedent infections were reported in 556 patients (72%), and this proportion did not significantly differ between those testing positive or negative for a recent infection. The proportions of infections were similar across continents. The sensorimotor variant and the demyelinating electrophysiologic subtype were most frequent across all infection groups, although proportions were significantly higher in patients with a cytomegalovirus and significantly lower in those with a C. jejuni infection. C. jejuni-positive patients were more severely affected, indicated by a lower Medical Research Council sum score at nadir (p = 0.004) and a longer time to regain the ability to walk independently (p = 0.005). The pure motor variant and axonal electrophysiologic subtype were more frequent in Asian compared with American or European C. jejuni-positive patients (p < 0.001, resp. p = 0.001). Time to nadir was longer in the cytomegalovirus-positive patients (p = 0.004). DISCUSSION: Across geographical regions, the distribution of infections was similar, but the association between infection and clinical phenotype differed. A mismatch between symptom reporting and serologic results and the high frequency of coinfections demonstrate the importance of broad serologic testing in identifying the most likely infectious trigger. The association between infections and outcome indicates their value for future prognostic models.

Campylobacter jejuni subdural hygroma infection in a 2-year old boy: case report and a brief literature review.

BACKGROUND: Campylobacter jejuni is a common cause of acute gastroenteritis, but central nervous system infections are rare manifestations of Campylobacter infection. Therefore, C. jejuni trauma-related subdural hygroma infection in children is poorly described in the literature. CASE PRESENTATION: We described a 2-year old boy with lobar holoprosencephaly presenting with subdural hygroma following head trauma. C. jejuni infection was confirmed from a subdural hygroma sample by culture as well as by DNA sequencing of a broad range 16S rDNA PCR product. Cerebrospinal fluid from the ventriculoperitoneal shunt remained sterile. Combined neurosurgical and antimicrobial treatment led to complete recovery. Review of the literature showed that the most common manifestation of Campylobacter central nervous system infection is meningitis, mostly in neonates, and subdural hygroma infection was described for only one case. CONCLUSIONS: Subdural hygroma infection caused by C. jejuni is a rare clinical condition in children. Molecular methods represent an important tool for the detection of rare or unexpected pathogens. No standard recommendations for antimicrobial treatment of C. jejuni subdural space infection in children are available, but meropenem treatment combined with surgery seems to be an effective approach.

Campylobacter jejuni Pericarditis: A Case Report.

Campylobacter jejuni is one of the most common causes of enteritis. In rare cases, extraintestinal infection can occur, with a handful of cases of cardiac involvement, of which the pathophysiological mechanism is unclear. We report a case of pericarditis in a patient with X-linked agammaglobulinemia presenting with chronic diarrhea and chest pain who evolved to cardiac tamponade, requiring a pericardial window and a long course of broad-spectrum antibiotics. To the best of our knowledge, this is the third case of pericarditis caused by Campylobacter jejuni reported in the literature, the second in a patient with X-linked agammaglobulinemia. Despite its rarity, this case serves as a reminder of Campylobacter as a potential cause of cardiac inflammation for clinicians treating pericarditis/myocarditis, especially in patients with a history of diarrhea or immunosuppression.

A Campylobacter jejuni é uma das causas mais comuns de enterite. A infeção extraintestinal pode ocorrer raramente, estando reportados alguns casos de atingimento cardíaco, de mecanismo fisiopatológico incerto. Reportamos um caso de pericardite num doente com agamaglobulinemia ligada ao X, que se apresentou como diarreia crónica e dor torácica, evoluindo para tamponamento cardíaco com necessidade de confeção de janela pericárdica e tratamento prolongado com antibióticos de largo espectro. Este é, tanto quanto é do nosso conhecimento, o terceiro caso de pericardite por Campylobacter jejuni reportado na literatura, o segundo em doente com agamaglobulinemia ligada ao X. Apesar da sua raridade, este caso serve para reforçar a importância do género Campylobacter como causa de inflamação cardíaca para médicos que tratem pericardite/miocardite, especialmente em doentes com história de diarreia ou imunossupressão.
