Abstract
BACKGROUND Acute hepatitis due to various tropical infections can mimic the clinical picture of acute viral hepatitis(AVH), leading to increased morbidity and mortality. We aimed to identify clinical and laboratory parameters that could help to distinguish acute hepatitis due to tropical infections from AVH. METHODS We retrospectively analyzed our database of 150 children (107 boys) with AVH and 50 children(34 boys)with acute hepatitis due to tropical infections between January 2013 and March 2023. Clinical features, investigations, complications and outcomes were compared. RESULTS Hepatitis A (75%) was the commonest etiology of AVH while enteric fever (34%), dengue (26%), scrub typhus (20%) and leptospirosis (16%) constituted the majority of tropical infections. Persistent fever and skin rashes were found in 88% and 16% of patients respectively in the tropical infection group and none in the AVH group (p < 0.001). On univariate analysis, prodromal symptoms, clinically detectable jaundice, cholestatic pattern, total and direct bilirubin and liver enzymes were significantly higher in AVH while headache, myalgia, leukopoenia, thrombocytopenia, hyponatremia were significantly higher in tropical infections group (all p < 0.05). Multivariate analysis identified thrombocytopenia (Odds ratio [OR] 4.237) as an independent positive predictive factor and markedly elevated total bilirubin (OR 0.575), direct bilirubin (OR 0.498), aspartate aminotransferase (OR 0.841) and alanine aminotransferase (OR 0.863) as independent negative predictive factors for acute hepatitis due to tropical infections. CONCLUSION High index of suspicion for tropical infections is warranted in patients with persistent fever after the onset of jaundice, especially in the presence of skin rash and thrombocytopenia.SUMMARYAcute viral hepatitis and acute hepatitis due to tropical infections can have similar clinical and biochemical parameters. Milder degree of jaundice, lower elevation of serum transaminases and thrombocytopenia can be useful predictors for acute hepatitis due to tropical infections.

Abstract
Typhoid fever is a potentially life-threatening infectious disease that presents itself with a wide array of symptoms ranging from uncomplicated fever to sepsis with multiorgan dysfunction syndrome. An 18-year-old male college student presented with progressively increasing fever with abdominal discomfort, anorexia, and persistent vomiting. Typhoid fever was suspected in view of clinical findings along with leukopenia, grossly elevated transaminases, and acute kidney injury. He was managed with intravenous (IV) antibiotics, which resulted in the resolution of fever and other symptoms. Rhabdomyolysis is an extremely rare complication in typhoid fever, which is a very common cause of fever in tropical countries, leading to acute renal failure, causing very high morbidity and mortality.

Abstract
BACKGROUND A large number of patients admitted to the medical intensive care unit (MICU) have abnormal liver function tests (LFT). This includes patients with critical illness with or without preexisting liver disease and patients with acute primary liver injury. There are very few studies which have investigated the spectrum of liver disease, clinical profile and outcome in patients admitted to the MICU. OBJECTIVE To evaluate the occurrence, etiology, clinical profile, laboratory profile and outcome of hepatic dysfunction in patients admitted to the MICU. To evaluate the utility of model for end-stage liver disease (MELD) score on admission as a predictor of adverse short term outcome in patients with hepatic dysfunction admitted in MICU. METHODS It was a prospective observational study, conducted from December 2017 to December 2018 in a tertiary care hospital. Two hundred and two patients admitted to the MICU with LFTs as per the inclusion criteria were analyzed and their short-term outcome at 7 days was studied in relation to various parameters. RESULTS LFT abnormalities were present in 202/1126 (17.9%) of the patients admitted to MICU. Critical illness associated liver dysfunction was found in 172 (85.2%) patients, chronic liver disease in 11 (5.4%) patients and acute viral hepatitis in 19 (9.4%) patients. Most common symptom was fever (68.3%) followed by vomiting (48.0%). Among LFT abnormalities, elevated transaminases, raised international normalized ratio and high MELD score on admission correlated with poor short-term outcome. Requirement for inotropes and mechanical ventilation correlated with poor short-term outcome. Mortality did not differ significantly between patients with chronic liver disease, patients with acute viral hepatitis and patients with critical illness associated hepatic dysfunction. Hepatic dysfunction in MICU was associated with poor outcome and a high short-term mortality of 56.4% (114/202). CONCLUSION Liver function abnormality is common in patients who are admitted to the MICU and its presence is an indicator of poor short-term outcome.

Abstract
Persistent infections generally involve a complex balance between protective immunity and immunopathology. We used a murine model to investigate the role of inflammatory monocytes in immunity and host defense against persistent salmonellosis. Mice exhibit increased susceptibility to persistent infection when inflammatory monocytes cannot be recruited into tissues or when they are depleted at specific stages of persistent infection. Inflammatory monocytes contribute to the pathology of persistent salmonellosis and cluster with other cells in pathogen-containing granulomas. Depletion of inflammatory monocytes during the chronic phase of persistent salmonellosis causes regression of already established granulomas with resultant pathogen growth and spread in tissues. Thus, inflammatory monocytes promote granuloma-mediated control of persistent salmonellosis and may be key to uncovering new therapies for granulomatous diseases.

Abstract
INTRODUCTION Typhoid fever is a major health problem in developing countries. Extensively drug-resistant (XDR) typhoid is an emerging threat to world health. The objectives of this study were to report our blood culture proven patients having XDR typhoid and compare the rate of gastrointestinal (GI) and hepatobiliary manifestations and complications of antimicrobial sensitive and resistant strains. MATERIALS AND METHODS This prospective observational study was carried out at a tertiary care hospital in Pakistan, from January 2019 till August 2020 on all consecutive blood culture proven patients of Salmonella typhi. A total of 57 cases of Salmonella were identified, of which 10 were nonresistant, seven multi drug-resistant (MDR), 39 extensively drug-resistant (XDR), and one was extended-spectrum beta lactamase (ESBL) positive. Alarmingly, one of the S. typhi isolate in addition to the first line drugs, was also resistant to azithromycin. Patients were treated with antibiotics according to antimicrobial susceptibility of the Salmonella in accordance with the World Health Organization (WHO) and Medical Microbiology and Infectious Diseases Society of Pakistan (MMIDSP) guidelines and GI and hepatobiliary complications were recorded. RESULTS Overall rate of complications was low. Some 10% (1/10) with nonresistant typhoid, 14% (1/7) with MDR, and 15% (6/39) of our patients with XDR typhoid fever had abdominal tenderness (p=0.95). None of the patients had GI bleeding, abdominal abscess, or peritonitis. Some 20% (2/10) patients with nonresistant typhoid, 29% (2/7) with MDR, and 18% (7/39) with XDR typhoid developed acute hepatitis, with greater than three times elevation of liver transaminases. There was no statistically significant difference in the occurrence of hepatitis between these groups (p=0.98). Interestingly, one of our patients with XDR typhoid also developed cholestatic hepatitis. CONCLUSION There is no significant difference in GI and hepatobiliary complications amongst antimicrobial sensitive and resistant strains of typhoid. However, emergence of resistant strains calls for focus on prevention and judicious use of antimicrobials.

Selenium Treatment Enhanced Clearance of Salmonella in Chicken Macrophages (HD11). Antioxidants (Basel) 2019; 8:antiox8110532.

Abstract
As an important micronutrient, selenium (Se) plays many essential roles in immune response and protection against pathogens in humans and animals, but underlying mechanisms of Se-based control of salmonella growth within macrophages remain poorly elucidated. In this study, using RNA-seq analyses, we demonstrate that Se treatment (at an appropriate concentration) can modulate the global transcriptome of chicken macrophages HD11. The bioinformatic analyses (KEGG pathway analysis) revealed that the differentially expressed genes (DEGs) were mainly enriched in retinol and glutathione metabolism, revealing that Se may be associated with retinol and glutathione metabolism. Meanwhile, Se treatment increased the number of salmonella invading the HD11 cells, but reduced the number of salmonella within HD11 cells, suggesting that enhanced clearance of salmonella within HD11 cells was potentially modulated by Se treatment. Furthermore, RNA-seq analyses also revealed that nine genes including SIVA1, FAS, and HMOX1 were differentially expressed in HD11 cells infected with salmonella following Se treatment, and GO enrichment analysis showed that these DEGs were mainly enriched in an extrinsic apoptotic signaling pathway. In summary, these results indicate that Se treatment may not only affect retinol and glutathione metabolism in macrophages, but could also inhibit salmonella-induced macrophage apoptosis via an extrinsic apoptotic signaling pathway involving SIVA1.

Abstract
Slaughterhouse workers (SHW) are at increased risk of hepatitis which can occur due to different organisms and should be investigated for viral, bacterial, and parasitic organisms. Slaughter house personnel including butchers are at a higher risk of infections from cuts and blood-letting, with the possible risk of the transmission of blood-borne pathogens to their colleagues. The objective of this review is to evaluate the common etiologies of hepatitis in SHW which will assist in the assessment of these patients presenting with transaminitis. Types of Microorganisms causing hepatitis with their reservoirs, routes of transmission, laboratory diagnosis, clinical features, treatment options and preventive strategies are included in this review. Proper investigation and awareness is of utmost importance as it causes significant financial constraints derived from workers health cost and from livestock production losses when the disease is confirmed. The work up is essential because infected workers might be a source of infections to other colleagues, family and the consumers.

Abstract
Background Enteric fever, a common infection in the tropics and endemic to India, often manifests as an acute febrile illness. However, presentation as fever of unknown origin (FUO) is not uncommon in tropical countries. Methods We aim to describe the clinical, laboratory and pathological features of patients hospitalized with fever of unknown origin and diagnosed as enteric fever. All culture proven cases of enteric fever were analyzed retrospectively over a period of three years from January 2011 to December 2013. Results Seven of 88 (8%) cases with enteric fever presented as FUO. Abdominal pain was the most common symptom besides fever. Relative bradycardia and splenomegaly were uncommon. Thrombocytopenia was the most common haematological abnormality while leucopenia was rare. Transaminase elevation was almost universal. S. Typhi and S. Paratyphi A were isolated from six cases and one case respectively. Yield of organisms from blood culture was superior to that of bone marrow aspirate. Multiple granulomas were identified in 4 out of 6 (67%) of the bone marrows studied, including that due to S. Paratyphi A and histiocytic hemophagocytosis was noted in two cases. Conclusion FUO is a relatively common manifestation of enteric fever in the tropics. Clinical and laboratory features may be atypical in such cases, including absence of relative bradycardia, leucopenia, and presence of thrombocytopenia, bicytopenia or pancytopenia. In addition, in endemic countries, enteric fever should be considered as a differential diagnosis, next to tuberculosis, in the evaluation of bone marrow granulomas in cases with FUO and culture correlation should be mandatory.

Toll-Like receptor 2 (TLR2) and TLR9 play opposing roles in host innate immunity against Salmonella enterica serovar Typhimurium infection. Infect Immun 2015; 83:1641-9.

Abstract
Toll-like receptors (TLRs) are evolutionarily conserved host proteins that are essential for effective host defense against pathogens. However, recent studies suggest that some TLRs can negatively regulate immune responses. We observed here that TLR2 and TLR9 played opposite roles in regulating innate immunity against oral infection of Salmonella enterica serovar Typhimurium in mice. While TLR9-/- mice exhibited shortened survival, an increased cytokine storm, and more severe Salmonella hepatitis than wild-type (WT) mice, TLR2-/- mice exhibited the opposite phenomenon. Further studies demonstrated that TLR2 deficiency and TLR9 deficiency in macrophages both disrupted NK cell cytotoxicity against S. Typhimurium-infected macrophages by downregulating NK cell degranulation and gamma interferon (IFN-γ) production through decreased macrophage expression of the RAE-1 NKG2D ligand. But more importantly, we found that S. Typhimurium-infected TLR2-/- macrophages upregulated inducible nitric oxide synthase (iNOS) expression, resulting in a lower bacterial load than that in WT macrophages in vitro and livers in vivo as well as low proinflammatory cytokine levels. In contrast, TLR9-/- macrophages showed decreased reactive oxygen species (ROS) expression concomitant with a high bacterial load in the macrophages and in livers of TLR9-/- mice. TLR9-/- macrophages were also more susceptible than WT macrophages to S. Typhimurium-induced necroptosis in vitro, likely contributing to bacterial spread and transmission in vivo. Collectively, these findings indicate that TLR2 negatively regulates anti-S. Typhimurium immunity, whereas TLR9 is vital to host defense and survival against S. Typhimurium invasion. TLR2 antagonists or TLR9 agonists may thus serve as potential anti-S. Typhimurium therapeutic agents.

Abstract
Objective: Early differentiation of enteric (typhoid) fever from other febrile conditions has been difficult due to the non-specific clinical presentations and lack of substantiating laboratory clues. Transaminase alterations in enteric fever were thought to be non-specific and have not been investigated before in comparison with other febrile conditions with regards to their prevalence and the aspartate amino transferase/alanine amino transferase (AST/ALT) ratio. We sought to examine these parameters as triage markers for enteric fever. Methods: We retrospectively studied 106 patients with enteric fever diagnosed by positive blood culture. 112 febrile patients tested negative for malaria were taken as controls. The controls were matched to the test group with respect to demographic and baseline clinical features. Serum AST, ALT values on first visit to the emergency department was noted and AST/ALT ratio was determined. The values between the test and control groups were compared and the results were analyzed using appropriate statistical methods. Results: The mean AST and ALT levels were found to be significantly higher for enteric fever patients than the control group (109.91 U/L ± 76.07 vs. 29.93 U/L ± 16.74; p < 0.0001) and (83.60 U/L ± 68.04 vs. 32.12 U/L ± 21.79; p < 0.0001) respectively. The mean AST/ALT ratio was found to be higher among enteric fever patients compared to the control group (1.42 ± 0.60 vs.1.07 ± 0.44; p < 0.0001). AST/ALT ratio of ≥ 1 combined with AST of ≥ 40 U/L was found in 72.6% of enteric patients vs. 6.2% in the control group (p < 0.0001). Conclusions: As compared to other common febrile conditions, transaminase alterations in enteric fever seem to follow a specific pattern characterized by higher prevalence of mild elevations (mean levels < 3 fold the upper limit of normal) with a general trend of AST/ALT ratios ≥ 1. In the febrile adult, having an AST/ALT ratio of >1 combined with an AST level of >40 U/L, may provide a simple and cheap triage marker for blood cultures and closer observation especially in the emergency department.

Abstract
Salmonella Typhi asymptomatic chronic carriage represents a challenge for the diagnosis and prevention of typhoid fever in endemic areas. Such carriers are thought to be reservoirs for further spread of the disease. Gallbladder carriage has been demonstrated to be mediated by biofilm formation on gallstones and by intracellular persistence in the gallbladder epithelium of mice. In addition, both gallstones and chronic carriage have been associated with chronic inflammation and the development of gallbladder carcinoma. However, the pathogenic relationship between typhoid carriage and the development of pre-malignant and/or malignant lesions in the hepatopancreatobiliary system as well as the host-pathogen interactions occurring during chronic carriage remains unclear. In this study, we monitored the histopathological features of chronic carriage up to 1 year post-infection. Chronic cholecystitis and hepatitis ranging from mild to severe were present in infected mice regardless of the presence of gallstones. Biliary epithelial hyperplasia was observed more commonly in the gallbladder of mice with gallstones (uninfected or infected). However, pre-malignant lesions, atypical hyperplasia and metaplasia of the gallbladder and exocrine pancreas, respectively, were only associated with chronic Salmonella carriage. This study has implications regarding the role of Salmonella chronic infection and inflammation in the development of pre-malignant lesions in the epithelium of the gallbladder and pancreas that could lead to oncogenesis.

Abstract
We report an unusual presentation of sacroiliitis and hepatitis secondary to Salmonella systemic infection. A high index of suspicion, early blood cultures, prompt investigations and treatment with parenteral antibiotics can result in complete resolution of symptoms and prevent long-term sequelae of either condition.

Abstract
Typhoid fever is a very common infectious disease of tropics, associated with high morbidity and mortality. Typhoid fever is often associated with hepatomegaly and mildly deranged liver functions; a clinical picture of acute hepatitis is a rare complication. We report a young patient who presented with fever and jaundice and was found to have acute hepatitis secondary to typhoid fever. Recognition of Salmonella hepatitis is of clinical importance as it can mimic acute viral hepatitis. Early institution of specific therapy can improve the prognosis in these patients.

Abstract
Salmonella infection occurs worldwide and is still an important public health problem in many developing countries. The infection can affect almost all major organs including the liver. Severe hepatic involvement with a clinical feature of acute hepatitis is a rare complication. In this paper, a 39-year-old male with acute cholestatic typhoid hepatitis is presented. The case had a tender hepatomegaly and elevated serum alanine and aspartate transaminase, alkaline phosphatase, and gamma glutamyl transferase levels; these features cannot been distinguished from those of acute viral hepatitis. Serological and viral markers of acute viral hepatitis were negative. No pathology could be determined in abdomen Ultrasonography (USG) or Magnetic Resonance (MR) Cholangiography. As enteric fever is a common infection, the recognition of salmonella hepatitis is of clinical importance. When patients from an endemic or outbreak area present acute febrile hepatitis, typhoid fever should be a consideration.

Abstract
The liver plays an important role in host defense against invasive microorganisms. The effect of microbial pathogens on the liver can vary greatly, presenting with a wide variety of manifestations from asymptomatic increases in aminotransaminases, acute liver failure, hepatic fibrosis, and cirrhosis. In evaluating the liver manifestations of a potential infectious pathogen, diagnosis of some of the less common infectious pathogens is dependent on a high level of suspicion and recognition of some of the key diagnostic clues. Successful diagnosis can only be accomplished through a careful history, including travel and exposures, physical examination, and appropriate microbiologic studies. This article reviews the involvement of the liver during systemic infections with organisms that are not considered to be primarily hepatotropic.

Abstract
BACKGROUND Typhoid fever is caused by Salmonella enterica serotype Typhi (5. typhi). Growing communication between Taiwan and neighboring regions in recent years could be an important source of typhoid fever. The aim of this study was to analyze the clinical characteristics of typhoid fever treated at a medical center in southern Taiwan. METHODS The study group consisted of 33 patients (aged 1-68 years) who had clinical symptoms and culture-confirmed typhoid fever. They were studied over a 20-year period from January 1987 to December 2006 at a tertiary referral hospital in southern Taiwan. Their medical records were reviewed and clinical data were collected. RESULTS The study group included 17 males and 16 females. They were divided into two groups: group I (< or = 17 years; n=14) and group II (>17 years; n=19). Only one patient (7.1%) in group I had a history of travel, compared with 47.4% (n=9) in group II (p = 0.045). Patients in group I also had less chills (group I vs. group 11=7.1% vs. 57.9%, p = 0.004). A higher proportion of group I patients had respiratory problems (cough, group I vs. group II = 57.1% vs. 26.3%) and a higher proportion of group II patients developed complications (group I vs. group II = 14.3% vs. 36.8%), but the differences were not significant. CONCLUSION Pediatric patients with typhoid fever in southern Taiwan had less history of travel and developed fewer chills than adult patients. Careful examination and familiarity with the clinical manifestations are important factors in the early diagnosis of typhoid fever.

Abstract
The innate immune system represents a critical first line of host response to infectious, injurious and inflammatory insults. NKT cells (natural killer T-cells) are an important, but relatively poorly understood, component of the innate immune response. Moreover, NKT cells are enriched within the liver, suggesting that within the hepatic compartment NKT cells probably fulfil important roles in the modulation of the immune response to infection or injury. NKT cells are characterized by their rapid activation and secretion of large amounts of numerous types of cytokines, including those within the Th1-type, Th2-type and Th17-type groups, which in turn can interact with a multitude of other cell types within the liver. In addition, NKT cells are capable of participating in a wide array of effector functions with regards to other cell types via NKT cell-surface-molecule expression [e.g. FASL (FAS ligand) and CD40L (CD40 ligand)] and the release of mediators (e.g. perforin and granzyme) contained in cellular granules, which in turn can activate or destroy other cells (i.e. immune or parenchymal cells) within the liver. Given the huge scope of potential actions that can be mediated by NKT cells, it has become increasingly apparent that NKT cells may fulfil both beneficial (e.g. clearance of virally infected cells) and harmful (e.g. induction of autoimmunity) roles in the setting of liver disease. This review will outline the possible roles which may be played by NKT cells in the setting of specific liver diseases or conditions, and will discuss the NKT cell in the context of its role as either a ‘friend’ or a ‘foe’ with respect to the outcome of these liver disorders.

Abstract
A 27-year-old man was admitted with high fever and shivers eleven days after returning from vacation in Indonesia. Physical examination, laboratory values, abdominal ultrasound, and chest x-ray were not conclusive. All blood cultures yielded growth of Salmonella enterica serovar Typhi, and typhoid fever was diagnosed. Subsequently, the patient developed septic shock and pulmonary edema. In this case report epidemiological, clinical, and therapeutic aspects of typhoid fever are discussed with special emphasis on criteria for severe typhoid fever, which is treated with additional glucocorticoids.

Abstract
Mycoplasma pneumoniae has been associated with cholestatic hepatitis in children, while in adults, the lack of liver involvement has been considered as a typical feature of M. pneumoniae infection. Controversial data have been reported about the possibility of liver involvement with M. pneumoniae community-acquired pneumonia. We present two cases of acute hepatitis associated with M. pneumoniae infection without lung involvement.

Abstract
During the course of typhoid fever, the usual histologic finding of the liver is "nonspecific reactive hepatitis." Hepatic granuloma (HG) is a rare complication of typhoid fever. We present two cases of typhoid fever with HG and review the relevant literature. Case 1 (a 53-year-old female) was found to have both hepatic and splenic granulomas. This is the first case of typhoid fever with splenic granulomas in the English language literature. Case 2 (a 66-year-old male) developed granulomas in the bone marrow in addition to HG. It should be considered that typhoid fever may lead to granulomas in several organs.

Abstract
BACKGROUND & AIMS Toll-like receptors (TLRs) for bacterial constitutes are expressed not only by phagocytes but also by some subsets of T cells. We previously reported that natural killer T cells (NKT cells) play an important role in liver injury induced by Salmonella infection. In the present study, we investigated whether TLRs on NKT cells are involved in Salmonella-induced liver injury. METHODS Gene expression of TLR2 was examined in sorted natural killer, NKT, and T cells from livers of naive mice by the reverse-transcription polymerase chain reaction method. Serum alanine aminotransferase level and FasL expression on liver lymphocytes were examined in TLR2-deficient (TLR2(-/-)) and FasL-deficient gld/gld mice before and after intraperitoneal inoculation of Salmonella choleraesuis 31N-1 using an enzyme-linked immunosorbent assay and flow cytometry. RESULTS TLR2 gene was abundantly expressed by NKT cells freshly isolated from naive mice. FasL expression on liver NKT cells increased in TLR2(+/-) mice but not in TLR2(-/-) mice after Salmonella infection. Serum alanine aminotransferase level was significantly lower in the TLR2(-/-) and gld/gld mice than in the control mice after infection. CONCLUSIONS TLR2 may contribute to liver injury induced by Salmonella infection via FasL induction on liver NKT cells.

Abstract
BACKGROUND Enteric fever remains a major cause of fever in travelers. We evaluated new trends in enteric fever. METHODS We reviewed the epidemiological, clinical, biological, bacteriological data, and outcome of all cases of typhoid and paratyphoid fever seen in our department over the last decade. The inclusion criteria were the presence of signs compatible with enteric fever and isolation of Salmonella typhi or Salmonella paratyphi A, B, or C from blood or stool cultures or any other site. RESULTS Among the 41 patients, 38 (93%) had travel-associated enteric fever. The main geographic source of contamination was the Indian subcontinent. One patient had been vaccinated with parenteral Vi vaccine 1 year previously. Fever and headaches were the only signs which were present in more than 80% of patients. The Widal test at inclusion was positive in 27%, and a second serological test was found to be positive in 50% of evaluated cases. Blood cultures and stool cultures were positive in 34 cases and 10 cases, respectively. Salmonellae spp were isolated in both hemocultures and stool cultures in 4 cases and in urine in 1 case. Two strains of S. typhi were resistant to ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole. One strain of S. typhi and one of S. paratyphi B were nalidixic acid resistant. All evaluable patients were cured with the exception of 2 patients (1 failure, 1 relapse). We observed 3 toxic reactions. No patients died. CONCLUSION The diagnosis and outcome of enteric fever are hampered by the lack of specificity of clinical and biological signs, the increasing rates of antimicrobial resistance, and the occurrence of toxic reactions during treatment.
