We surveyed stool and urine specimens from 245 Saudi Arabian trainees for parasites. Schistosoma mansoni eggs were found in the stool in 66 (26.9%) and S. haematobium eggs were recovered from the urine in 1 (0.4%). Additional parasites were recovered in 167 (68.2%) of the survey group and were not more common in those with schistosomiasis (P greater than .10). Schistosome egg counts ranged from 0--6,320 eggs/g feces (mean 447.9). When patients with high egg counts (over 400 eggs/g) were compared with uninfected controls, abdominal complaints and fatigue were found to be more frequent (P less than .05) in the infected group, as was eosinophilia (P less than .001). Other laboratory and physical examination findings were equally present in both groups. This study reaffirms the value of quantitative examination of stool specimens for schistosome eggs.

Two of three members (a 29-year-old man [case 1] and a 26-year-old woman [case 2]) of a tourist party to the tropics (Mali) developed a high fever (less than or equal to 40 degrees C), headache, cough, weight loss (less than or equal to 5 kg) and tiredness 3-4 weeks after returning to Germany. In case 1, acute schistosomiasis was tentatively diagnosed as the cause because he reported an attack of dermatitis after exposure to fresh water in an endemic schistosomiasis region and had marked eosinophilia (2118/microliters; 28%) on admission. Serological tests were positive (ELISA with adult antigen, O.D. 0.65 [normal less than 0.15]; with egg antigen O.D. 1.73 [normal less than 0.30], antibody titre in the immunofluorescence test 1:320 [normal less than 1:80]) supported the diagnosis and it was confirmed by demonstrating the parasite, Schistosoma mansoni, in stool but not urine. Findings in case 2 were similar. The third member of the group [case 3], a 58-year-old woman, was symptom-free, but tests revealed schistosomiasis. All three patients were treated with a single dose of Praziquantel (40 mg/kg). A second course of praziquantel (single dose of 40 mg/kg as well as 20 mg/kg three times daily for 3 days) became necessary in case 1, while in case 3 a further single dose of 40 mg/kg was given to ensure a parasite-free state. A follow-up scheme is suggested: clinical examination with white cell and differential counts 1, 3, 6 and 12 months after treatment; three stool and/or urine examinations 3, 6 and 12 months after treatment.

Morbidity due to infection with Schistosoma mansoni was investigated in a recently discovered highland focus around Lake Cohoha, Burundi. The distribution of the infection was very focal and morbidity patterns in populations from an endemic area A (prevalence 38%, mean egg load of positive subjects 231 eggs per gram [epg]), a less affected area B (16%, 90 epg) and a virtually non-endemic area C (5%, 45 epg), were compared; apart from schistosomiasis, the profiles of these populations were highly similar. The overall frequencies of diarrhoea were 36%, 25%, and 19%, respectively; of abdominal pain 86%, 78%, and 83%; of fatigue 7%, 2%, and 1%; of left lobe hepatomegaly 30%, 18%, and 9%; of right lobe hepatomegaly 18%, 10%, and 5%; of splenomegaly 18%, 10%, and 7%. Organomegaly was generally mild, even in area A. Within area A, the association between the presence of infection and diarrhoea, fatigue, hepatomegaly and splenomegaly was significant, but far less impressive than the results of the community-based comparison with areas B and C. The correlation with intensity was limited to an increased prevalence of diarrhoea and fatigue in the highest egg count group, and a more gradual increase (varying with age) in hepatomegaly and splenomegaly. The data are compared to other morbidity studies in subsaharan Africa, in particular one in the nearby Rusizi Plain. The lesser impact of malaria, the higher egg loads, the recent establishment of the focus and possibly parasite strain differences may account for the more apparent and more important schistosomiasis morbidity in the Cohoha focus.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical features in 173 white expatriates returning to Britain with the sole diagnosis of schistosomiasis were compared with those in non-infected control subjects, matched for age and sex, returning from similar endemic areas. Infection was, with one exception, acquired in Africa. Schistosoma mansoni was found in 135 patients, S haematobium in 29, and mixed infection in 9. 79% of patients with S haematobium had symptoms, compared with 47% of patients with S mansoni. Tiredness, headache, and gastrointestinal disturbance were no more frequent in symptomatic patients than in control subjects. In over 50% of patients with schistosomiasis the diagnosis was established from snips of rectal mucosa, and this raises the question of how best to look for infection in those who have been exposed. Urine examination and schistosomal serology appear to be the best screening methods; patients with haematuria or seropositivity should be investigated further.

Two young men with Salmonella bacteraemia, active schistosomiasis and the acquired immunodeficiency syndrome are reported. The clinical presentation comprised nonspecific signs and symptoms, such as fatigue, malaise, weight loss, diarrhoea, prolonged fever, and hepatosplenomegaly. In one patient, liver biopsy showed poorly formed granulomata around Schistosoma mansoni eggs and hepatitis. Treatment of schistosomiasis alone induced consistent clinical improvement with eventual cure of both Salmonella and S. mansoni infections. Recognition of the Salmonella-S. mansoni association in patients with AIDS is important because treatment of schistosomiasis makes a difference, improving the prognosis of this otherwise, recurrent, potentially fatal bacteraemia.

In areas where there is a low prevalence of schistosomiasis mansoni, faecal examination is a relatively insensitive method of detection and infected people may also be missed because most show only mild morbidity. In such settings, serology may be a more useful diagnostic tool than microscopy. In the present study, the clinical and biochemical characteristics of individuals who were stool-positive for Schistosoma mansoni eggs were compared with those of individuals, from the same low-prevalence area of Brazil, who were stool-negative but seropositive for the parasite. Overall, 269 subjects were checked both for schistosome eggs in their faeces (using Kato-Katz smears and Lutz sedimentation) and for anti-S. mansoni IgG in their sera (using an ELISA). Although 128 (48%) of these subjects were found seropositive, only 26 (10%) were found to be egg excretors and two of the egg excretors were seronegative. Compared with the seropositive egg-negatives, the egg excretors had significantly higher frequencies of fatigue, melaena, jaundice and swelling of the abdomen. The egg excretors also had higher frequencies of hepatomegaly (20% v. 16%) and splenomegaly (4% v. 1%). In both groups of subjects, mean concentrations of serum proteins and haemoglobin and mean leucocyte counts were in the normal range whereas most blood concentrations of alanine aminotransferase and many of those of aspartate aminotransferase were slightly elevated. Although the egg excretors tended to have low-intensity infections, it seems possible that the seropositive nonexcretors had even milder infections that could not be detected by faecal examination. The high frequency of cure observed when the egg excretors were given praziquantel at 40 mg/kg (94%) is probably another indication that most had light infections when they were treated.

Schistosomiasis is caused by trematode parasites of one of five species, Schistosoma mansoni, Schistosoma haematobium, Schistosoma japonicum, Schistosoma intercalatum, or Schistosoma mekongi, acquired via skin contact with fresh water containing infectious larval cercariae. Between 1 and 8 weeks after exposure, acute schistosomiasis presents as dermatitis, fever, fatigue, or eosinophilia. If untreated, long-term infection may cause anemia or undernutrition and may progress to liver fibrosis, portal hypertension, or hydronephrosis. Schistosomiasis represents a threat to residents and visitors in all endemic areas of Africa, Asia, and South America. Travelers should be made aware of infection risk if they become exposed to untreated fresh water. New immigrants and those returning to high-risk areas to visit friends and family should be screened for signs and symptoms of acute and chronic schistosomiasis. Physicians caring for travelers and immigrants must be familiar with the signs and symptoms of schistosomiasis and must be able to diagnose and treat it correctly.
