[A foci of Schistosomiasis mekongi rediscovered in Northeast Cambodia: cultural perception of the illness; description and clinical observation of 20 severe cases].
In 1992 a foci of Schistosomiasis mekongi was rediscovered in the province of Kracheh in Northeast Cambodia. Severe clinical signs due to portal hypertension, which were frequently observed in this population, allowed the discovery of this 'forgotten' focus. Elements of the perception of the population and clinical observations of 20 severe cases due to S. mekongi infections are presented. Interviews with patients and villagers of the area of Kracheh showed severe psychosocial impact including fear from death, infirmity and invalidity. The symptoms of schistosomiasis were well known by the population and were reported to have increased in frequency in the last two decades. They have received traditional names and specific traditional treatment. The description of the clinical cases illustrates the severe pathology, which was observed in the hospital of Sambour, in the north of the province of Kracheh. It shows the pathogenic potential of S. mekongi in all age groups (from 7 to 58 years old): cachexia, hepatosplenomegaly, stunting and retardation of puberty, decompensation of portal hypertension with ascites and rupture of oesophagual varicies. The efficacy of the treatment in the severe stages varies. A follow-up after 30 months showed that 5 patients died, 5 initially improved but then relapsed, 3 remained unchanged and only 5 patients clearly improved. Two patients could not be followed-up. The clinical observations and interviews show severe pathology with impact at both individual and community level. The infection with S. mekongi is the main factor but additional concomitant factors are responsible for this fact. At a certain stage of the disease the prognosis for successful treatment is very low. These observations show the importance of the foci in the Province of Kracheh, Cambodia and underline the need for a long-term global intervention.
