Typhoid fever (The Enteric Fever)

Def: It is an acute infective disease characterized by continued fever, splenomegaly, bacillaemia, involvement of intestinal lymphatic tissue and usually a roseolar eruption.

Aetiology- Causative organism- Salmonella Typhi (a gram negative bacillus) .Predisposing cause : Age –5 to 35 years. Sex- both, males prcdominate, Season- mostly autumn. Incubation period  about 10 to 14 days.
Source of infection: Food, flies, fingers, faces, filth and fomite etc.

Pathogenesis: After a few days of bacteremia, the bacilli localize mainly in the lymphoid tissue of the small intestine. The typical lesson is in the peyer’s patches and follicles. These swell at first, them ulcerate and ultimate heal, but during this sequence they may perforate or bleed. The mesenteric lymph nodes and spleen are enlarged.

Clinical Features: Onset is insidious.
Stage of invasion (1st week)-1. Temperature rises in a step ladder fashion with a progressive evening rise and ½ to 1 drop each morning, face flushed. 2. Relative bradycardia with dicrotic pules. 3. Coated tongue with red margins and tip. 4. Headache, constipation, loss of appetite, lassitude, malaise. 5. Abdomen swollen with gurgling over caecum, may be pain and discomfort. 6. Spleen just palpable. 7. Rash may appear at the end of week.

State of Fastigium (2nd week)-1. Temperature continuous but high. 2. Headache less marked, becomes mentally dull, week and stuporose. 3. Constipation replaced by peasoup diarrhoea. 4. Dry coated tongue, pulse shows tachycardia, cough may supervene. 5. Distended abdomen and tender on palpation.6. Spleen enlarged and liver may just palpable. 7. Rashes may be present. 8. Evidence of bronchitis and bronchopneumonia (sometime). 9. Muttering delirium, coma and vigil may be present at the end of 2nd week.

Stage of Defervescence (3rd week) – 1. More exhausted, delirium and muscular twitching. 2. Dry and shiny tongue. 3. Muscular wasting. 4. Homorrhage and perforation may occur. 5. Abdomen more distended. 6.Temperature begins to fall by lysis (rarely bycrisis).


Stage of Convalescence (4th week) –1. Temperature normal in the mornings, a little higher in the evening. 2. Abdominal reflexes reappear. 3. Spleen not palpable. [3rd and 4th week-various complications gradually develop. But fortunately now-a-days these] stages are not seen.

Investigations:- Typhoid fever may be mistaken for Influenza Gastroenteritis, Pneumonia, Nephritis or Meningitis.
1st week: 1. Blood culture – positive.
  2.Leucocytecount – leucopenia with relative lyucocytosis.
2nd week: 1. Widal’stest is positive.
3rd and 4th week: 1. Widal’s test positive.2. Stool and urine culture positive.

Complications: 1. Intestinal –  haemorrhage,  perforation and peritonitis. 2. Venous thrombosis. 3. Respiratory – laryngitis, bronchitis, pneumonia, pleural effusion, lung abscess. 4. Cardiac – myocarditis, endocarditis and pericarditis, acute peripheral circulatory failure. 5. Nervous, - Meningitis, convulsion, coma, delirium post-typhoid insanity, typhoid state, meningism, neuritis osteomy-elitis, spondylitis etc.

The Typhoid State:- It is a condition of extreme prostration, often with semi consciousness and delirium, which may rise in any toxaemia of sufficient gravity . The patient may be comatose, restless and confused, with dry skin and sores (crusted sores) around the mouth, also may be incontinent of urine and faces. It is seen in severe toxanemia , viz. typhoid or Typhus fever, Acute Lobar Pneumonia, Acute Pulmonary
tuberculosis, infective endocarditis, Acute meni
ngitis, Encephalitis lethargica.

Treatment of Typhoid Fever: - Prophylaxis – T.A.B. Vaccine 1ml. subcutaneously, repeated after 10 days.

Curative -1. General nursing care including mouth, eyes and skin are important. 2. Bed rest until temperature is normal for 2 weeks. 3. Diet should be high caloric and in the form of liquids. 4. Milk horlicks, fluid and electrolytic balance to be maintained. 5. Purgatives should never the prescribed. 6. For high temperature tepid sponging advised.
