Presentation
Material And Methods We present a review of 32 cases of Chronic schistosomiasis presenting over a span of 4 years (2001 to 2005) at King Faisal Hospital, Taif, Kingdom of Saudi Arabia. [ispub.com]
Nuclear and mild cytoplasmic immunoreactivity for HBcAg was present in some hepatocytes. [uscapknowledgehub.org]
Clinical Management Schistosomiasis has a broad spectrum of clinical presentations, and up to 10% of patients may have severe hepatosplenic presentation. [onlinelibrary.wiley.com]
Chronic Schistosomiasis may present in a wide variety of forms: Urinary schistosomiasis usually caused by S. haematobium – painful urination (dysuria), and blood in urine (hematuria). [web.stanford.edu]
If present, it usually takes four to six weeks for symptoms to appear. The first symptom of the disease may be a general ill feeling. [encyclopedia.com]
Entire Body System
- Chills
Within 1-2 months of infection, symptoms may develop including fever, chills, cough, and muscle aches. Without treatment, schistosomiasis can persist for years. [cdc.gov]
Many parasites may cause fever, chills, swollen lymph nodes, and swollen liver and spleen. When the worm first gets into the skin, it may cause itching and a rash (swimmer's itch). In this condition, the schistosome is destroyed within the skin. [ufhealth.org]
Large invasions may cause fever, chills, and lymph node, liver, and spleen enlargement After this initial phase one to three months may pass before the acute phase of the disease is manifested. [web.stanford.edu]
[…] depending on the type of worm involved and the location of the parasite inside the body, and can include initial itching and rash at infection site (“swimmer’s itch”) Frequent, painful or bloody urine Abdominal pain and bloody diarrhea Anemia Fever, chills [sabin.org]
Immune System
- Splenomegaly
Usually, these patients will present with portal hypertension signs and symptoms, including splenomegaly, gastroesophageal varices, hematemesis, and ascites. Hepatic function is commonly preserved until late stages 2. [radiopaedia.org]
Periportal fibrotic bands and widened fissures Capsular calcification (parallel or perpendicular to liver surface) • Portal hypertension in advanced disease Splenomegaly and varices • US: Bull’s-eye lesion: Represents anechoic portal vein surrounded by [radiologykey.com]
Imaging studies may reveal enlargement of the left liver lobe without changes in the liver parenchyma or splenomegaly. [onlinelibrary.wiley.com]
The chronic consequences of Schistosoma mansonii infection include portal hypertension with splenomegaly, esophageal varices, and ascites. [coursera.org]
On examination there was massive splenomegaly with minimal ascites. Magnetic resonance imaging revealed minimally shrunken liver with nodular regenerative hyperplasia. All autoimmune and viral markers were negative. [tropicalgastro.com]
Gastrointestinal
- Constipation
Gastrointestinal (GI) and hepatic S. mansoni and S. japonicum eggs most commonly lodge in the blood vessels of the liver or intestine and can cause diarrhea, constipation, and blood in the stool. [infectiousdiseaseadvisor.com]
Liver, Gall & Pancreas
- Hepatosplenomegaly
The relative risk to develop hepatosplenomegaly in persons infected with S. mansoni have been reported in correlation with HLA-A1 and B5[ 15 ]. [wjgnet.com]
Hepatosplenomegaly and lymphadenopathy are usual. Chronic Schistosomiasis may present in a wide variety of forms: Urinary schistosomiasis usually caused by S. haematobium – painful urination (dysuria), and blood in urine (hematuria). [web.stanford.edu]
Portal hypertension can develop and cause hepatosplenomegaly, ascites, and esophageal varices. [meddean.luc.edu]
[…] nervous system. schistosomiasis manso´ni infection with Schistosoma mansoni, living chiefly in the mesenteric veins but migrating to deposit eggs in venules, primarily of the large intestine; eggs lodging in the liver may lead to peripheral fibrosis, hepatosplenomegaly [medical-dictionary.thefreedictionary.com]
The patients presented with hepatosplenomegaly and portal hypertension. Ultrasound examination showed hepatomegaly and portal fibrosis. [ispub.com]
Skin
- Erythema
Symptoms depend on the severity of the cirrhosis, but may include: appetite loss nausea weight loss general tiredness spidery red veins on the skin (spider angiomas) easily bruised skin yellowing of the skin and eyes (jaundice) reddened palms (palmar erythema [betterhealth.vic.gov.au]
Spider nevi, gynecomastia, and palmar erythema are rare in uncomplicated schistosomiasis. A hard, enlarged liver with a predominant increase of the left lobe is frequently palpable. [elsevier.es]
Workup
X-Ray
- Gastric Varices
varices Pulmonary Venous Hypertension Schistosome eggs can be lodged in the lungs Dyspnea, cough, fatigue, swelling of lower extremities, pulmonary edema Can lead to cardiac failure No cure, only 50% patients clinically responsive to treatment Untreated [quizlet.com]
varices – essentially, varicose veins in the esophagus and stomach, one of the most serious complications because they can rupture and bleed. [liversupport.com]

- Liver Biopsy
Subsequently, a percutaneous ultrasound-guided liver biopsy was performed ( Figure 1 ) that revealed the diagnosis of hepatic schistosomiasis. Figure 1. Histological features of liver biopsy (haemotoxylin & eosin stain). [academic.oup.com]
The liver biopsy is submitted for review. Histological Features The biopsy consisted of two thin cores of liver tissue with 20 portal tracts. [uscapknowledgehub.org]

Treatment
Estimates show that at least 220.8 million people required preventive treatment in 2017. Preventive treatment, which should be repeated over a number of years, will reduce and prevent morbidity. [who.int]

Prognosis
[…] normal-appearing liver • US elastography demonstrates hepatic fibrosis • MR shows same morphologic signs as CT of liver damage and portal hypertension MR elastography provides a measure of extent of hepatic fibrosis, which may determine therapy and prognosis [radiologykey.com]
Outlook (Prognosis) Treatment before significant damage or severe complications occur usually produces good results. [ufhealth.org]
Prognosis If treated early, prognosis is very good and complete recovery is expected. The illness is treatable, but people can die from the effects of untreated schistomiasis. [encyclopedia.com]
What is the prognosis (outcome) for schistosomiasis? Early antiparasitic treatment, especially with acute schistosomiasis, may allow people to recover completely without developing chronic disease. [medicinenet.com]

Prevention Unclean water sources play an essential role in the life cycle of the parasitic worms and must be addressed to improve methods of prevention. [news-medical.net]
Prevention Prevention of the disease involves several targets and requires long term community commitment. Infected patients require diagnosis, treatment, and education about how to avoid reinfecting themselves and others. [encyclopedia.com]
Preventing schistosomiasis There's no vaccine for schistosomiasis, so it's important to be aware of the risks and take precautions to avoid exposure to contaminated water. [nhs.uk]
