Anguillulosis: circumstances of infestation and evolution towards the malignant form

INTRODUCTION

Anguillulosis is a ubiquitous digestive parasitosis. Rare in Tunisia, it is due to a round worm, strongyloid stercoralis, whose natural lodging is the duodeno-jejunal mucosa. Its malignant form is rare but it represents a potentially life-threatening disease.

AIM

We report a case of malignant anguillulosis occurring in a context of immunosuppression.

OBSERVATION

The case we report is about a 46-year-old man treated by a long-term corticosteroid therapy for Takayasu disease. He was hospitalized for an acute digestive syndrome. Biopsies were performed but the evolution was rapidly marked by multiorgan failure, sepsis and death of the patient. Histological analysis of the digestive biopsies concluded to an oeso-gastroduodenal anguillulosis.

CONCLUSION

Anguillulosis is a rare parasitosis but it can pose a health problem especially in its malignant form wich can be a life-threatening.

Utility of qSOFA and modified SOFA in severe malaria presenting as sepsis

Sepsis can be caused by malaria infection, but little is known about the utility of the quick Sequential (Sepsis-Related) Organ Failure Assessment (qSOFA) and SOFA score in malaria. We conducted a prospective observational study from March 2013 to February 2017 to examine adults admitted with community-acquired infection in a tertiary-care hospital in Ubon Ratchathani, Northeast Thailand (Ubon-sepsis). Subjects were classified as having sepsis if they had a modified SOFA score ≥2 within 24 hours of admission. Serum was stored and later tested for malaria parasites using a nested PCR assay. Presence of severe malaria was defined using modified World Health Organization criteria. Of 4,989 patients enrolled, 153 patients (3%) were PCR positive for either Plasmodium falciparum (74 [48%]), P. vivax (69 [45%]), or both organisms (10 [7%]). Of 153 malaria patients, 80 were severe malaria patients presenting with sepsis, 70 were non-severe malaria patients presenting with sepsis, and three were non-severe malaria patients presenting without sepsis. The modified SOFA score (median 5; IQR 4–6; range 1–18) was strongly correlated with malaria severity determined by the number of World Health Organization severity criteria satisfied by the patient (Spearman’s rho = 0.61, p<0.001). Of 80 severe malaria patients, 2 (2.5%), 11 (14%), 62 (77.5%) and 5 (6%), presented with qSOFA scores of 0, 1, 2 and 3, respectively. Twenty eight-day mortality was 1.3% (2/153). In conclusion, qSOFA and SOFA can serve as markers of disease severity in adults with malarial sepsis. Patients presenting with a qSOFA score of 1 may also require careful evaluation for sepsis; including diagnosis of cause of infection, initiation of medical intervention, and consideration for referral as appropriate.

Severe Plasmodium knowlesi infection with multiorgan involvement in north east peninsular Malaysia

Plasmodium knowlesi has been recently identified as the "fifth human malaria species" following the discovery in Malaysian Borneo of a large focus of this simian malaria parasite in humans. Even though it shares microscopic similarities with Plasmodium malariae, it may cause severe illness with risk of fatality. We describe a case of P. knowlesi infection causing multi-organ failure in a patient who was successfully managed due to early recognition of the infection. Clinicians in this region should be more aware of the infection as it is not as rare as previously thought. This case write up highlight the case of severe malaria infection which presented with multi organ involvement which is caused by P. knowlesi.

Plasmodium vivax malaria--is it really benign?

It is believed that most of the serious and life threatening complications are caused only by P falciparum infection while P vivax infections are relatively mild and run a benign course and usually not required hospitalisation but in the last few years hospitalisation rate and complications are also increasing in P vivax infection; so we planned this study to evaluate the severity and complicated presentation of P vivax malaria. This hospital-based study conducted in Jawahar Lal Nehru Hospital Ajmer, India. One hundred and two indoor patients with isolated P vivax malaria were included in this study with exclusion of other causes of fever including P falciparum malaria. All patients of severe and complicated P vivax malaria were admitted and treated as severe P falciparum malaria. Severe complications like significant hepatomegaly, thrombocytopenia, acute renal failure, severe anaemia, leucopoenia, electrolyte disturbance, acute respiratory distress syndrome, cerebral malaria, multiorgan dysfunction, hepatic dysfunction, pancytopenia, and death seen in 21.57%, 18.63%, 11.76%, 8.82%, 5.88%, 5.88%, 3.92%, 2.94%, 1.96%, 1.96%, 0.98%, 1.96% patients respectively. A significant proportion of morbidity and mortality in malaria also observed in P vivax infection as seen in P falciparum infection and require hospitalisation.

Strongyloides stercoralis septicaemia following steroid therapy for eosinophilia: report of three cases

Three apparently immunocompetent patients died in the intensive care unit at Loni Hospital, Ahmednagar, Maharashtra, India, between 2001 and 2006 due to multiorgan failure and Strongyloides stercoralis septicaemia following a short course of corticosteroid (prednisolone) therapy of 6-17 days for peripheral blood eosinophilia associated with urticaria and angioneurotic oedema, bronchospasm, and generalised aches and pains, respectively. None of the patients had any obvious lymphoproliferative disorder, solid tumour or HIV 1+2 infection as an underlying immunosuppressive condition. These three patients highlight the extreme caution that must be exercised in administering a moderate dose of oral corticosteroid even for a short period of time as well as the high degree of suspicion that needs to be maintained if there is clinical deterioration following corticosteroid therapy.

Malarial hepatitis as a component of multiorgan failure--a bad prognostic sign

A prospective study among the patients (n = 301) belonging to the coastal districts of Orissa having complicated falciparum malaria with multiorgan failure fulfilling modified APACHE II criteria, for a period of two years in this hospital setting was carried out with particular emphasis on hepatic involvement. There were 206 males and the rest females. Hepatic involvement in the form of raised serum bilirubin levels > or = 6 mg% and prothombin time > 4 compared to controls was found in 192 cases (63.8%). On analysis out of 192 cases predominantly conjugated hyperbilirubinaemia, mixed patterns and unconjugated hyperbilirubinaemia were seen in 115 (59.9%), 64 (33.3%) and 13 (6.8%) cases respectively. Serum bilirubin ranged from 6 to 38 mg%. Aminotransferase aspartate (AST, SGOT) and aminotransferase alkaline (ALT, SGPT) were raised almost two-fold in 98% cases of multiorgan failure with hepatic failure with mean values of 78 +/- 30.4 IU/l and 81 +/- 29.06 IU/l respectively. Nearly three-fold elevation of alkaline phosphatase was observed in 80% cases with mean (315 +/- 39.4 IU/l). Prothombin time was prolonged with mean 7 +/- 3 seconds. Serum proteins and albumin/globulin ratio were normal. There was no difference in glycaemic status over controls. In selected cases, liver histopathological study showed abnormalities in the form of Kupffer cell hyperplasia, mononuclear cell infiltration, hepatocyte necrosis, fatty changes and cholestasis. Majority of patients in multiorgan failure who died, had hepatic failure.

Drotrecogin alfa (activated) in severe falciparum malaria

Drotrecogin alfa (activated) is a drug licensed for the treatment of severe sepsis. We describe the care of a 61-year-old man who developed multi-organ failure secondary to severe falciparum malaria infection with parasitaemia levels of 40%. Included in his care were an exchange blood transfusion and an infusion of Drotrecogin alfa (activated). Within hours of starting the infusion of Drotrecogin alfa (activated), the patient's clinical condition stopped deteriorating. Steady improvement followed with weaning from ventilatory assistance on day 14 post admission. The patient made a full recovery and was discharged home following rehabilitation. The indications for Drotrecogin alfa (activated) and the appropriateness of its use in severe malaria with multi-organ failure are discussed. Drotrecogin alfa (activated) may be a useful treatment in patients with multi-organ failure resulting from severe malaria.

Plasma glucose and tumour necrosis factor-alpha in adult patients with severe falciparum malaria

Plasma glucose was assessed in 81 patients with severe falciparum malaria at the time of presentation along with tumour necrosis factor-alpha (TNF-alpha). The lowest plasma glucose value was 3.38 mmol/l and none of the patients had hypoglycaemia at admission. Plasma glucose values were not significantly lower in those with multiple organ dysfunction (MOD) than in patients with single organ dysfunction (cerebral malaria only) and in those who died compared with patients who survived. Conversely, TNF-alpha showed a good correlation with depth of coma and was significantly higher in patients who had MOD and those who died. There was no correlation between plasma glucose and TNF-alpha values.

Intensive care management of multiple-organ dysfunction due to falciparum malaria in a married couple

A married couple presented simultaneously with malignant tertian malaria and rapidly developed septicaemia and severe multiple-system organ failure. Despite schizonticidal treatment and multisystem support in intensive care the husband died. The selection of chemoprophylactic agents for this couple was not ideal and the duration of therapy before exposure to risk was inadequate. Severe infection with plasmodium falciparum is life-threatening and requires early diagnosis. It is best managed in an intensive care unit where continuous assessment may enable rapid detection of clinical deterioration and allow appropriate treatment to be instituted. The diagnosis should be considered in symptomatic patients who have travelled through areas where malaria is endemic. Recognised guidelines for the prescription of malarial chemoprophylaxis should be followed to ensure adequate protection.

[Multiple organ failure (MOF) in tertian malaria. Report of a clinical case]

The authors describe a malignant malaria clinic case complicated by shock, disseminated intravascular coagulation (DIC) and multiple organ failure (renal, heart, lung failure): MOF. Early diagnosis and suitable therapy, with multiple organ failure intensive care allowed a good patient outcome.
