An Unusual Hematological Complication of Typhoid Fever Case Report.

Typhoid fever is caused by Salmonella species. The most common hematological complications described are anemia and disseminated intravascular coagulation. Splenic infarction is an unusual complication of typhoid fever, and this presentation is rarely described. We report the case of a young female who presented with complaints of severe left upper quadrant pain after being diagnosed with typhoid fever. Computed tomography (CT) revealed multiple wedge-shaped splenic infarcts. She was treated with antibiotics and was also started on antiplatelets. She had a complete recovery with this management, and antiplatelets were tapered off on subsequent visits.

Primary Aortoenteric Fistula Due to Salmonella typhi-related Mycotic Aneurysm.

Primary aortoenteric fistulas (AEF) are rare. The majority of these are due to atherosclerotic aortic aneurysms. Mycotic aortic aneurysms leading to primary AEF are exceedingly uncommon. Here we report a rare case of primary AEF secondary to Salmonella-related mycotic aneurysm and discuss the diagnostic and therapeutic issues.

Defunctioning ileostomy for typhoid ileal perforations: Out of the frying pan into the fire?

Typhoid ileal perforation (TIP) is a common surgical emergency in low-middle income countries (LMICs). Its high surgical morbidity and mortality is due to its often late presentation or diagnosis, the patient's malnutrition, severe peritoneal contamination and unavailability of intensive care in most peripheral hospitals. This prompted the philosophy of minimizing the crisis by avoiding any repair or anastomosis, limiting the surgery in these physiologically compromised patients and performing only a temporary defunctioning ileostomy (DI) which could then be closed 10-12 weeks later.

Enteric Fever-Associated Hemophagocytic Lymphohistiocytosis: A Systematic Review of Clinical Characteristics and Outcomes.

Enteric fever is a major contributor to rising health care costs in developing countries. Associated disease-related complications and drug resistance further compound this problem. Hemophagocytic lymphohistiocytosis (HLH) is an uncommon complication of enteric fever with high morbidity and mortality. This systematic review aimed to evaluate the clinical characteristics and treatment outcomes in enteric fever-associated HLH syndrome. We searched major electronic databases (PubMed, Google Scholar, and Scopus) to identify the cases of enteric fever associated with HLH from inception until June 2023. Prespecified data regarding clinical presentation, outcomes, and HLH therapy were collected. A total of 53 cases of enteric fever with HLH were included in the final analysis. The mean age of patients was 20 years, and the proportions of female and pediatric patients were 52.8% and 45.3%, respectively. The mean duration of illness was 10.4 days. A total of 39.6% of patients had enteric fever-associated complications; coagulopathy and encephalopathy were the most common (23.1% and 13.5%). The overall mortality rate was 9.4% in HLH. A total of 51% of patients received HLH-specific therapy (corticosteroids in 41.5% and intravenous immunoglobulin in 20.8% of patients). On multivariate analysis, high ferritin levels (≥5,000 ng/mL) were significantly associated with mortality (hazard ratio, 3.01; 95% CI = 0.62-14.12, P = 0.041). Enteric fever with secondary HLH is associated with high mortality. This review reveals the potential role of ferritin in disease prognosis. In cases with significantly elevated ferritin levels, the role of immunosuppressants or combination antibiotics should be explored.

Typhoid Fever Presenting with Ileal Perforation and Gastric Perforation.

Typhoid fever is caused by Salmonella typhi and Salmonella paratyphi. It is a disease of developing countries and is seen among people of low socio-economic status. Patients can develop complications like typhoid intestinal perforation which is associated with higher mortality. A 15-year-old female presented to the emergency pediatric unit with fever, abdominal pain and abdominal distension. She was septic, in respiratory distress, and had marked generalized abdominal tenderness with guarding. An assessment of generalized peritonitis secondary to typhoid intestinal perforation was made. She had exploratory laparotomy with intra-operative findings of ileal perforation and gastric perforation. She had repair of the intestinal and gastric perforations. Our patient presented late with concurrent use of NSAIDs and overwhelming sepsis which likely contributed to the gastric perforation as this is not a usual finding in patients with typhoid intestinal perforation. Gastric perforation is an unusual finding in patients with typhoid intestinal perforation. Typhoid fever and its complications can be easily prevented by the provision of safe water, proper facilities for sanitation, and practicing good hygiene.

La fièvre typhoïde est causée par Salmonella typhi et Salmonella paratyphi. C'est une maladie des pays en développement et elle est observée chez les personnes de bas niveau socio-économique. Les patients peuvent développer des complications telles que la perforation intestinale typhoïdique, associée à une mortalité plus élevée. Une adolescente de 15 ans s'est présentée à l'unité de pédiatrie d'urgence avec de la fièvre, des douleurs abdominales et une distension abdominale. Elle était septique, en détresse respiratoire, et présentait une sensibilité abdominale généralisée marquée avec une défense. Une évaluation d'une péritonite généralisée secondaire à une perforation intestinale typhoïdique a été réalisée. Elle a subi une laparotomie exploratrice révélant une perforation iléale et une perforation gastrique. Des réparations ont été effectuées sur les perforations intestinales et gastriques. Notre patiente s'est présentée tardivement avec une utilisation concomitante d'AINS et une septicémie sévère, ce qui a probablement contribué à la perforation gastrique, car cela n'est pas une découverte habituelle chez les patients atteints de perforation intestinale typhoïdique. La perforation gastrique est une découverte inhabituelle chez les patients atteints de perforation intestinale typhoïdique. La fièvre typhoïde et ses complications peuvent être facilement prévenues par la fourniture d'eau potable, d'installations sanitaires adéquates et en pratiquant une bonne hygiène MOTS-CLÉS: fièvre typhoïde, perforation intestinale, perforation gastrique.

Sensorineural hearing loss as an atypical presentation of typhoid fever: A case report.

Typhoid fever, also known as enteric fever, is a multisystemic infection primarily caused by Salmonella enterica serotype Typhi, and less commonly by Salmonella enterica serotypes Paratyphi A, B, and C. The classic presentation includes fever, malaise, diffuse abdominal pain, and constipation. If left untreated, typhoid fever can progress to delirium, obtundation, intestinal haemorrhage, bowel perforation, and death within a month of onset. However, the clinical course can deviate from the classic stepladder fever pattern, which now occurs in as few as 12% of cases.1 In this report, we describe an atypical presentation as sensorineural hearing loss in an otherwise healthy young male.

Hemophagocytic lymphohistiocytosis following enteric fever: A rare autopsy case report.

ABSTRACT: Hemophagocytic lymphohistiocytosis (HLH) is a severe and frequently underdiagnosed disorder of systemic immune dysregulation resulting in hypercytokinemia and histologically evident hemophagocytosis, We report a case of a 34-year-old man who presented with breathlessness, generalized weakness, and fever of unknown origin with pancytopenia. Clinically the patient was admitted for febrile illness, and treated symptomatically but his general condition worsened leading to death within 21 hours of admission. A complete autopsy was performed. The deceased had a significant past history of repeated episodes of fever, weight loss, and axillary lymphadenopathy over a period of 8 months with multiple hospital admissions. He was also diagnosed with enteric fever (Widal test and Typhi IgM positive) at the start of these episodes. Hemogram during this period revealed persistent pancytopenia. Serum ferritin, serum triglycerides, and liver function tests were consistently deranged. Investigations for the etiology of fever and blood cultures were negative while the bone marrow aspirate revealed a normocellular marrow. CT abdomen-pelvis showed mild hepatomegaly with enlarged retroperitoneal lymph nodes. Infective endocarditis, lymphoma, and bronchopneumonia were being considered the clinical diagnoses. The significant autopsy findings were hepatosplenomegaly with retroperitoneal lymphadenopathy and multiple gastric ulcers. On microscopy, the liver, spleen, bone marrow, and lymph nodes showed characteristic hemophagocytosis. Post-mortem histopathological examination clinched the diagnosis of HLH and fulfilled six out of eight diagnostic criteria of the HLH-2004 protocol. We discuss the clinical course and diagnosis of this unique case and strive to create awareness about secondary HLH induced by common diseases, such as enteric fever.

Case Report: A Case of Complicated Typhoid Fever with Rhabdomyolysis and Hemophagocytic Lymphohistiocytosis.

Typhoid fever can have diverse extra-intestinal complications including encephalitis, Guillain-Barré syndrome, endocarditis, myocarditis, osteomyelitis, renal abscess, and splenic abscesses. Secondary hemophagocytic lymphohistiocytosis with rhabdomyolysis is a rare complication of typhoid fever. Here, we present the case of an adolescent with typhoid fever complicated by rhabdomyolysis and hemophagocytic lymphohistiocytosis.

Practical approach to a patient with fever who travelled to the tropics.

By 2030, an estimated 2 billion international tourist trips are expected annually worldwide, with citizens of Poland as important contributors. Illness rates among returnees from developing regions range between 43% and 79%. Properly diagnosing fever in these travelers is vital due to potentially serious implications. After visiting tropical and subtropical zones, the main health complaints are diarrhea, fever, and skin lesions. A reliable diagnosis begins with taking a comprehensive travel history and identifying potential risks. In travelers returning from sub­Saharan Africa, malaria caused by Plasmodium falciparum is the main cause of fever, affecting 50 in every 1000 cases. Among returnees from Southeast Asia, dengue is dominant, occurring in 50-60 per 1000 cases, and its prevalence rises significantly nowadays. Other significant diseases include chikungunya, Zika, typhoid fever, amebic liver abscess, and occasionally viral hemorrhagic fevers. SARS­CoV­2 and influenza viruses are crucial pathogens as well. An in­depth assessment of the travel history, combined with knowledge on tropical diseases, are key to the diagnostic process, and algorithms may be helpful in selecting appropriate tests and treatment methods.

Typhoid spondylodiscitis of the cervical spine.

Spinal infection comprises pyogenic and non-pyogenic spondylodiscitis. This condition may manifest with non-specific clinical symptoms, elevated infective parameters and imaging findings that are difficult to distinguish. The cornerstone of a definitive diagnosis and subsequent successful treatment lies in tissue analysis through culture and histopathological studies. In this context, we present a case of Salmonella pyogenic spondylodiscitis affecting the C5/C6 vertebrae, complicated by Salmonella bacteraemia and characterised by mechanical neck pain that curtails daily activities and overall functioning, although without neurological deficits. The uniqueness of this case stems from its occurrence in an immunocompetent individual from a non-endemic area, with no identifiable sources of Salmonella infection or preceding gastrointestinal symptoms.

Case Report: An Imported Case of Typhoid Fever Combined with Rhabdomyolysis and Multiple Organ Lesions in China.

Here, we report a case of blood culture-confirmed typhoid fever, rhabdomyolysis, and multiple organ damage that arrived in our country from overseas. A 23-year-old male patient presented at our hospital with fever and muscle pain; the condition progressed rapidly. Six days after the onset of symptoms, the patient developed rhabdomyolysis and liver/kidney damage; levels of creatine kinase (CK; maximum peak: 729,869 U/L) and myoglobin (> 3,000 ng/mL) were extremely high, although the extent of renal damage was relatively mild. Blood culture showed Salmonella typhi. The patient received a combination of meropenem and levofloxacin anti-infective therapy, as well as fluid and nutritional metabolic support. He gradually recovered and was discharged after two negative blood cultures. This case highlights the fact that typhoid-induced rhabdomyolysis is a serious, life-threatening disease and that the levels of CK and myoglobin are useful indicators for evaluating typhoid-induced rhabdomyolysis. Clinicians should remain vigilant regarding travel-related illnesses associated with enteric fever.

Investigating the etiology of acute febrile illness: a prospective clinic-based study in Uganda.

BACKGROUND: Historically, malaria has been the predominant cause of acute febrile illness (AFI) in sub-Saharan Africa. However, during the last two decades, malaria incidence has declined due to concerted public health control efforts, including the widespread use of rapid diagnostic tests leading to increased recognition of non-malarial AFI etiologies. Our understanding of non-malarial AFI is limited due to lack of laboratory diagnostic capacity. We aimed to determine the etiology of AFI in three distinct regions of Uganda. METHODS: A prospective clinic-based study that enrolled participants from April 2011 to January 2013 using standard diagnostic tests. Participant recruitment was from St. Paul's Health Centre (HC) IV, Ndejje HC IV, and Adumi HC IV in the western, central and northern regions, which differ by climate, environment, and population density. A Pearson's chi-square test was used to evaluate categorical variables, while a two-sample t-test and Krukalis-Wallis test were used for continuous variables. RESULTS: Of the 1281 participants, 450 (35.1%), 382 (29.8%), and 449 (35.1%) were recruited from the western, central, and northern regions, respectively. The median age (range) was 18 (2-93) years; 717 (56%) of the participants were female. At least one AFI pathogen was identified in 1054 (82.3%) participants; one or more non-malarial AFI pathogens were identified in 894 (69.8%) participants. The non-malarial AFI pathogens identified were chikungunya virus, 716 (55.9%); Spotted Fever Group rickettsia (SFGR), 336 (26.2%) and Typhus Group rickettsia (TGR), 97 (7.6%); typhoid fever (TF), 74 (5.8%); West Nile virus, 7 (0.5%); dengue virus, 10 (0.8%) and leptospirosis, 2 (0.2%) cases. No cases of brucellosis were identified. Malaria was diagnosed either concurrently or alone in 404 (31.5%) and 160 (12.5%) participants, respectively. In 227 (17.7%) participants, no cause of infection was identified. There were statistically significant differences in the occurrence and distribution of TF, TGR and SFGR, with TF and TGR observed more frequently in the western region (p = 0.001; p < 0.001) while SFGR in the northern region (p < 0.001). CONCLUSION: Malaria, arboviral infections, and rickettsioses are major causes of AFI in Uganda. Development of a Multiplexed Point-of-Care test would help identify the etiology of non-malarial AFI in regions with high AFI rates.

Malaria and typhoid fever among patients presenting with febrile illnesses in Ga West Municipality, Ghana.

BACKGROUND: Clinicians in areas where malaria and typhoid fever are co-endemic often treat infected patients irrationally, which may lead to the emergence of drug resistance and extra cost to patients. This study determined the proportion of febrile conditions attributable to either malaria and/or typhoid fever and the susceptibility patterns of Salmonella spp. isolates to commonly used antimicrobial agents in Ghana. METHODS: One hundred and fifty-seven (157) febrile patients attending the Ga West Municipal Hospital, Ghana, from February to May 2017 were sampled. Blood samples were collected for cultivation of pathogenic bacteria and the susceptibility of the Salmonella isolates to antimicrobial agents was performed using the Kirby-Bauer disk diffusion method with antibiotic discs on Müller Hinton agar plates. For each sample, conventional Widal test for the detection of Salmonella spp was done as well as blood film preparation for detection of Plasmodium spp. Data on the socio-demographic and clinical characteristics of the study participants were collected using an android technology software kobo-collect by interview. RESULTS: Of the total number of patients aged 2-37 years (median age = 6 years, IQR 3-11), 82 (52.2%) were females. The proportion of febrile patients with falciparum malaria was 57/157 (36.3%), while Salmonella typhi O and H antigens were detected in 23/157 (14.6%) of the samples. The detection rate of Salmonella spp in febrile patients was 10/157 (6.4%). Malaria and typhoid fever coinfection using Widal test and blood culture was 9 (5.7%) and 3 (1.9%), respectively. The isolates were highly susceptible to cefotaxime, ceftriaxone, ciprofloxacin, and amikacin but resistant to ampicillin, tetracycline, co-trimoxazole, gentamicin, cefuroxime, chloramphenicol, and meropenem. CONCLUSION: Plasmodium falciparum and Salmonella spp coinfections were only up to 1.9%, while malaria and typhoid fever, individually, were responsible for 36.3% and 6.4%, respectively. Treatment of febrile conditions must be based on laboratory findings in order not to expose patients to unnecessary side effects of antibiotics and reduce the emergence and spread of drug resistance against antibiotics.
