7/µL. Despite several peritoneal punctures, L loa could not be detected in ascitic fluid. The treatment consisted of an initial dose of ivermectin (150 µg/kg) and after a treatment-free period of 5 days, a 3-week course of diethylcarbamazine (DEC) was started. Following 5 days and a cumulative dose of 93.75 mg (first day 6.25 mg; second day 12.5 mg; third day 25 mg; fourth day 50 mg, and the dose given the fifth day was insignificant) of

DEC, an acute and severe encephalopathy concomitant to a respiratory distress appeared. This was unexpected since microfilaremia load was low. The patient developed a confusional state characterized by blurred vision and disorientation without any specific neurological defect. Albendazole 200 mg b.i.d was initiated 5 days after the neurological event and pursued for 4 weeks. This treatment has induced an important reduction in ascites and pleurisies. No neurological sequelae Olaparib order were noted at discharge and follow-up period. Microbiological cure was confirmed by the disappearance of blood microfilaremia. During 4 months of follow-up, there was

no reappearance of signs and symptoms suggesting the relapse of the disease. This case shows an original presentation with visceral involvement find more but absence of Calabar swellings, migration of the adult worm through the conjunctiva, and blood hypereosinophilia. In addition, the outcome was surprising given the occurrence of DEC-related encephalopathy despite low microfilaremia. Calabar swellings are angioedemas and the absence Chlormezanone of such clinical signs in our patient could be linked to an immune dysfunction, related to the patient’s cachexia. Patients may also experience the passage of the adult worm through the conjunctiva but this is an uncommon feature although it is one of the most commonly reported. These symptoms and signs may last for a long time, since adult worms may live for more than 17 years.1 Atypical cases of loiasis

involving visceral sites have been seldom reported. Indeed, macrofilaria is not known to enter into the organs, though extra-cutaneous manifestations of loiasis have been rarely described and most often limited to pleuropulmonary manifestations.2 Cases of isolated pleural and ascetic effusions have also been described3,4 and may be related to a very high parasitic load. However, this report is the first to describe a case of pleuroperitoneal loiasis associated with low parasitic load. Although L loa could not be isolated from peritoneal fluid, the clinical response to anti-helminthic treatment can reasonably be considered as a proof of diagnosis. Another explanation for the worms’ intrusion into pleuroperitoneal spaces may be due to extreme cachexia of our patient causing weak osmotic pressure due to very low albuminemia. The pathogenesis of the cardiac failure remains unclear. Cardiothyrotoxicosis is generally characterized by a hyperdynamic circulatory state.
