==Overview==
The majority of patients with schistosomiasis in early phase are asymptomatic, unless Katayama fever, an acute immune complex disease, occurs. Late Schistosomiasis is symptomatic and includes hepatosplenic schistosomiasis (presinusoidal portal hypertension), urinary and urogenital schistosomiasis (urinary obstruction, genital symptoms), schistosomal glomerulopathy (chronic immune complex deposition in the kidney), and ectopic disease in areas such as the lungs and central nervous system (CNS).

Overview

The majority of patients with schistosomiasis in early phase are asymptomatic, unless katayama fever, an acute immune complex disease, occurs. Late schistosomiasis is symptomatic and includes hepatosplenic schistosomiasis (presinusoidal portal hypertension), urinary and urogenital schistosomiasis (urinary obstruction, genital symptoms), schistosomal glomerulopathy (chronic immune complex deposition in the kidney), and ectopic disease in areas such as the lungs and central nervous system (CNS).

History

The significant information that needs to focused in the history of the patient includes

  • Any history of travel to the endemic areas
  • Any ill contact with similar complaints

Symptoms

Clinical manifestations of schistosomiasis can be divided into:

  • Schistosome dermatitis
  • Acute schistosomiasis (katayama fever)
  • Chronic schistosomiasis[1]

Acute schistosomiasis(Katayama fever)

Chronic schistosomiasis

Intestinal schistosomiasis

Schistosomal nephropathy

Urogenital schistosomiasis

Pulmonary schistosomiasis

Neuroschistosomiasis

  • In hospitalized adult patients with S. japonicum infection, cerebral schistosomiasis occurs in 1.7 to 4.3%.
  • It may occur as early as 6 weeks after infection, and the most common sign is focal jacksonian epilepsy.
  • Signs and symptoms of generalized encephalitis may occasionally be found.
  • In S. mansoni infection, neurologic involvement is rare and mainly characterized by transverse myelitis, which occurs mainly in patients without liver fibrosis and hepatosplenomegaly.

Schistosome dermatitis

  • Schistosome dermatitis, or swimmer's itch, is an uncommon manifestation seen mainly when avian cercariae penetrate the skin and are destroyed.[7][8]
  • Schistosome dermatitis is a sensitization phenomenon occurring in previously exposed persons.
  • The cercariae evoke an acute inflammatory response with edema, early infiltration of neutrophils and lymphocytes, and later invasion of eosinophils.
  • A pruritic papular rash occurs within 24 hours after the penetration of cercariae and reaches maximal intensity in 2 to 3 days.

The table below summarizes the symptoms of schistosomiasis

Symtoms
Acute schistosomiasis

(Katayama fever)

Chronic schistosomiasis Schistosomal nephropathy present with varying degrees of fatigue and asthenia
Intestinal schistosomiasis may develop episodic intestinal bleeding and tenesmus.

Hepatosplenic schistosomiasis may present with cataclysmic esophageal variceal hemorrhage.

Neuro-schistosomiasis may present with seizures, transverse myelitis or symptoms similar to those of cauda equina syndrome (eg, low back pain, lower extremity weakness, bowel and bladder symptoms) due to inflammation at the nerve roots

Granulomatous inflammation in the CNS can result in conus medullaris syndrome or schistosomal cerebritis (most commonly caused by S. japonicum)

Pulmonary schistosomiasis experience dyspnea on exertion, fatigue, and hemoptysis.
Schistosome dermatitis

Uncommon manifestation.

A pruritic papular rash occurs within 24 hours after the penetration of cercariae and reaches maximal intensity in 2 to 3 days.
