ENTERIC FEVER

Enteric Fever

Aka typhoid fever Systemic febrile illness that is most

commonly caused by Salmonella typhi less frequent causes are S. paratyphi A, S.

paratyphi B (S. schottmuelleri), and S. paratyphi C (Salmonella hirschfeldii).

Non-typhoidal Salmonellae (S. enteritidis and S. typhimurium)

classically present with sustained fever, abdominal tenderness, and hepatosplenomegaly

Uptodate Medical Desktop 17.1

Epidemiology

Most often foodborne Paratyphoid fever: exposures outside the home

purchase of food from street vendors) Typhoid fever: exposure within the household

Sharing utensils, presence of a patient with typhoid, lack of soap or adequate toilet facilities

Most px to hospitals with typhoid fever are children or young adults from 5-25 years old. <5 years old nonspecific illness that is not

recognized clinically as typhoid.

347, No. 22

Pathogenesis

Ingestion of contaminated food or water Infectious dose:103 – 105 CFU

Gastrointestinal infection: survive the gastric acid barrier* adhere and invade the small intestines M cell- epithelial cells overlying the Payer’s

Patches Direct penetration into the epithelial cells

S. typhi in the lamina propria recruitment of mononuclear cells and macrophage ingested but survive

Parry, C.; Dougan G; White N; Farrar J. (2002) Typhoid Fever. N Engl J Med, Vol. 347, No. 22

Pathogenesis

Incubation phase: Some remain in SI lymphoid tissues, others drain into mesenteric lymph nodes reticuloendothelial cells of the liver and spleen Incubation period ranges 3-60 days (usually 7-14d) Survive and multiply in the mononuclear phagocytic

cells of the lymphoid follicles, liver and spleen. Bacteremic phase: bacteria released from

sequestered intracellular habitat into bloodstream induce systemic and local humoral and cellular immune responses MC sites of secondary infection: liver, spleen, bone

marrow, gallbladder and payer’s patch of the terminal ileum


Pathogenesis

Chronic carrier (4%): asymptomatic carriers after acute infection persistence of Salmonellae in stool or urine for

more than one year. immunologic equilibrium- virulent bacteria

persist without causing disease but cannot be eliminated women Persons with biliary abnormalities such as gallstones Defect in the urinary tract (eg, urolithiasis, prostatic

hyperplasia) or concurrent bladder infection with Schistosoma

Clinical Manifestation

Febrile illness for 7-14d after ingestion of the causative microorganism in contaminated food or water ONSET: fever and malaise Presentation (end of the 1st week): fever,

influenza-like symptoms with chills (although rigors are rare), a dull frontal headache, malaise, anorexia, nausea, poorly localize abdominal discomfort, a dry cough, and myalgia, but with few physical signs

Relative bradycardia or pulse-temperature dissociation – not consistent



Diarrhea – more common in children Constipation – more common in adults Bronchitic cough – common in the early stage of

the illness Rose spots on the chest, abdomen and back Arthalgia and myalgia Bacteremic seeding focal extra-intestinal

complications of the central nervous system, hepatobiliary, cardiovascular, respiratory, genitourinary, and musculoskeletal systems (uncommon)



Classic Manifestation of untreated individuals: First week of illness — rising ("stepwise")

fever and bacteremia Second week — abdominal pain and rash

(rose spots, which are faint salmon colored macules on the trunk and abdomen)

Third week — hepatosplenomegaly, intestinal bleeding and perforation, related to ileocecal lymphatic hyperplasia of the Peyer's patches, may occur with secondary bacteremia and peritonitis.Uptodate Medical Desktop 17.1

Clinical and Laboratory Presentation of Typhoid Fever

Yaramis A; Yilchim I, Katar S; Ozbek M, Yakjin, Tas A, Hosoglu SInternational Pediatrics/Vol. 16/No. 4/2001 227

typical symptoms in adults such as cough, headache and constipation were uncommon, tending to occur in older children.

Common clinical signs of typhoid fever in adults such as relative bradycardia and rose spots were seldom documented

Complications

Occur in 10-15% of patients, more likely in patients who have been ill for >2 weeks.

Complications

GI bleeding, (MC): 10% Erosion of necrotic Payer’s patch through the wall

of the enteric vessel Intestinal perforation: 1-2%

Most serious comp Manifest as acute abd or increasing abdominal

pain, rising pulse, and hypotension. Typhoid encelopathy:

Often accompanies shock Commonly apathetic although arousable. Can be severely agitated, delirious, or obtunded.

Diagnosis

Diagnosis

Isolation of the microorganism Stool culture (30-40%)

often negative by the time systemic symptoms arise Blood culture (60-80%)

higher in the first week Reduced by prior use in antibiotics

Bone marrow culture (80-95%) especially useful if antibiotics therapy have already

been started Urine, rose spots and duodenal content (string

capsule) culture


Diagnosis

Serologic Test: detects agglutinating antibodies to O and H antigens of S. typhi Controversial High false positive because shares antigens with

other salmonella serotypes and cross-reacting epitopes with other Enterobacteriaceae.

Laboratory Findings Anemia Leukopenia Leukocytosis (more common in children) Aminotransaminases elevated


Mean total WBC was 7.3x103/mm3. Shift to left was found in 78%

38% anemic (Hb<12/dl), 10% thrombocytopenic (<105/mm3)

Elevated serum ALT and AST in 32% Antibiotic resistance were found as follows: (>50) levels were observed in 100 (32%)

ampicillin(17%); trimethoprim-sulfamethoxazole (5%); Ceftriaxone (4%); sulbactam-ampicillin (6%). No resistance to quinolones and chloramphenicol.

Yaramis A; Yilchim I, Katar S; Ozbek M, Yakjin, Tas A, Hosoglu SInternational Pediatrics/Vol. 16/No. 4/2001 227

Diagnosis

Confirmed Case

•Fever (T>38oC) > 3 days•Laboratory confirmed positive culture (blood, bone marrow, bowel fluid)

Probable Case

•Fever (T>38oC) > 3 days•(+) Serodiagnosis or antigen detection test•w/o isolation

Chronic Carrier

•Excretion of S. typhi in stools or urine >1 year after typhoid fever

Treatment

Treatment

60-90% are managed at home with antibiotics and bed rest.

Fluoroquinolones are the most effective drugs for the treatment of typhoid fever more rapidly effective and are associated with lower rates of

stool carriage than the traditional first-line drugs (chloramphenicol and trimethoprim–sulfamethoxazole).

Average fever-clearance time is less than four days, and the cure rates exceed 96 percent

no evidence of bone or joint toxicity, tendon rupture, or, in long-term followup, impairment of growth

Used at the maximal possible dose for a minimum of 10 to 14 days, and the patients should be carefully followed to determine whether they are excreting S. enterica serotype typhi in their feces


Treatment

2nd line: 3rd gen cephalosporins (ceftriaxone, cefixime, cefotaxime, and cefoperazone) and azithromycin are also effective drugs for typhoid.

3rd line: Aztreonam and Imipenem

Chloramphenicol, amoxicillin, and trimethoprim–sulfamethoxazole remain appropriate for the treatment in areas of the world where the bacterium is still fully susceptible to these drugs and where the fluoroquinolones are not available or affordable. inexpensive, widely available, and rarely associated

with side effects.Parry, C.; Dougan G; White N; Farrar J. (2002) Typhoid Fever. N Engl J Med, Vol.
