A randomized double blind study was performed to evaluate the tolerance and the acceptance of mefloquine alone (Lariam) compared to a combined drug regimen consisting of mefloquine, sulfadoxine and pyrimethamine (MSP; Fansimef) in the prophylaxis of malaria. 175 Europeans travelling to different malaria endemic areas received either mefloquine alone (250 mg/week) or its combination with sulfadoxine (500 mg/week) plus pyrimethamine (25 mg/week). One person taking mefloquine and two taking MSP discontinued the drug intake because of moderate clinical side effects. Mild and moderate adverse clinical reactions predominantly concerning the gastro-intestinal tract and the autonomous nervous system were reported with a significantly higher occurrence in the MSP group. With both prophylactic regimens, reversibly elevated liver enzyme activities (glutamate oxalate transaminase and glutamate pyruvate transaminase [GPT]) were observed after prophylaxis. The increase of GPT serum activity correlated significantly with relatively high GPT levels before prophylaxis in both groups. This finding suggests a limited use of both regimens in cases of liver dysfunction. One case of mefloquine-resistant Plasmodium falciparum malaria was observed from West Africa; this patient was cured by a standard regimen of chloroquine.

Between January and December 1996, we observed 64 children (mean age 8.3 years range 4.2 to 11.2 years) who required dialysis for severe acute renal failure secondary to Falciparum Malaria. All received anti malarial therapy and other supportive therapy as well as peritoneal dialysis. Out of these 28 died (43.8%). The children who died (Group I) compared to those who survived (Group II) differed significantly in age (mean +/- SD) (7.2 +/- 1.3 years vs. 9.2 +/- 2.1 years P < 0.05), plasma creatinine at presentation (645 +/- 104 mumol/L vs. 438 +/- 87 mumol/L P < 0.05), plasma bilirubin (2.1 +/- 0.3 mg/dL vs. 1.2 +/- 0.2 mg/dL P > 0.02) systolic BP (50 +/- 11 mmHg vs. 90 +/- 12 mmHg P0 < 0.01), diastolic BP (20 +/- 4 mmHg vs. 60 +/- 9 mmHg P < .01) .Hb level 5.3 +/- 0.4 g/dL vs. 8 +/- 1.3 gm/dL P < .02), time from diagnosis to referral (5.3 +/- 1.3 days vs. 8.9 +/- 2.1 days P < .05) and urine output (200 +/- 49 mL/24 h vs. 600 mL +/- 131 mL P < .01). There was no significant difference in gender, alanine transaminase (ALT) level, degree of fever, plasma Na or plasma K. Diarrhea was present in 29% of the children who died and in only 11% of those who survived (P > 0.05) and splenomegaly was found in 3% and 18% respectively (PO > .05).

In a study of the influence of malaria-associated renal impairment on plasma concentrations of bilirubin, 111 Indian cases of Plasmodium falciparum malaria who had >34.2 microM total bilirubin/litre plasma were investigated. As the aim was to exclude those cases who had concomitant hepatic or (non-malarial) renal dysfunction, 19 cases who had serum concentrations of alanine aminotransferase (ALT) or alkaline phosphatase (AP) that were at least double the normal mean values were withdrawn. Of the remaining 92 patients, 47 showed evidence of renal impairment, the other 45 having plasma concentrations of creatinine that were <177 microM/litre. Plasma concentrations of the liver enzymes ALT and AP were similar for those with and without renal impairment. The plasma concentration of conjugated bilirubin (P<0.02), that of total bilirubin (P<0.05) and the ratio between the two (P<0.01) were, however, all significantly higher in the 47 patients with renal impairment than in the 45 with apparently normal renal function. The plasma concentration of creatinine was found to be not only positively correlated with the plasma concentrations of total (r=0.34; P<0.01) and conjugated (r=0.41; P<0.001) bilirubin but also negatively correlated with the urinary excretion rate for conjugated bilirubin (r=-0.34; P<0.001). The malaria-associated mortality was significantly higher among the patients with renal impairment than among those with apparently normal renal function, with 12 and three deaths, respectively (P<0.001). With increasing renal impairment there therefore appears to be a fall in the renal excretion of conjugated bilirubin. This leads to a disproportionate rise in the plasma concentration of conjugated bilirubin and this, since bilirubin can be toxic to renal tissue, may further worsen the renal impairment.

Clinical presentation of Plasmodium falciparum malaria reflects a continuum from asymptomatic to multi-organ manifestation and death. Severe malaria is defined by the World Health Organization as a qualitative variable. We used the multi-organ dysfunction score (MODS) as a quantitative approach for severity in 29 patients with severe and complicated P. falciparum malaria to test its usefulness in discriminating different severity levels. The MODS on admission was highly correlated with the duration of symptoms after admission (r = 0.73, P < 0.001) and the serum level of tumor necrosis factor alpha (r = 0.41, P = 0.03). In addition, the simplified MODS, based mainly on clinical findings, was also correlated with liver and renal dysfunction during hospitalization (alanine transaminase, r = 0.42, P = 0.02; blood urea nitrogen, r = 0.45, P = 0.015). A score >or= 16 was associated with significantly longer disease duration (P = 0.018). Thus, this score might provide a predictive value for morbidity in P. falciparum malaria.

Western Bahr el Ghazal State is located in northwestern South Sudan, which is a tropical area subject to Plasmodium falciparum malaria epidemics. The aim of this study is to explore the epidemiological and clinical features of Plasmodium falciparum malaria in United Nations personnel stationed in this area. From July 2006 to June 2009, epidemiological data and medical records of 678 patients with Plasmodium falciparum malaria at the U.N. level 2 hospital were analyzed. The U.N. personnel were divided into individuals not immune to Plasmodium falciparum and individuals semi-immune to Plasmodium falciparum. The patients were divided into a chemoprophylaxis group (non-immune individuals who complied with the chemoprophylaxis regimen, 582 cases) and a no/incomplete chemoprophylaxis group (non-immune individuals who either did not fully comply with chemoprophylaxis or did not use it at all and semi-immune individuals who did not use chemoprophylaxis, 96 cases). Overall morbidity was about 11.3%. There was a significant difference in the morbidity of semi-immune and non-immune individuals (1.3% vs. 15.1%, P<0.001). Out of the total, 82.9% of cases occurred during the rainy season. The incidence of fever in the chemoprophylaxis group was significantly lower than in the no/incomplete chemoprophylaxis group (36.8% vs. 96.9%, P<0.001). Significant differences were observed between the two groups with respect to all other malaria-like symptoms except gastrointestinal symptoms, serum glucose level, platelet count, and alanine aminotransferase level. The incidence of complications was 1.2% (chemoprophylaxis group) and 44.8% (no/incomplete chemoprophylaxis group).The most common complication was thrombocytopenia, which was seen in 40.6% of the no/incomplete chemoprophylaxis group. In summary, Plasmodium falciparum malaria mainly occurred in rainy season. Gastrointestinal symptoms are an important precursor of malaria. Blood smears and rapid diagnostic tests should be performed after the onset of gastrointestinal symptoms. Appropriate chemoprophylaxis is necessary for reducing the severity of malaria.

Plasmodium falciparum malaria is the most common infection in Yemen. The present study aims to investigate changes in hematological and hepatic function indices of P. falciparum infected individuals. This study included 67 suspected falciparum malarial patients attended in clinics and rural Abs Hospital (Tehama, Hajjah), Yemen, from October 2013 to April 2014. The diagnosis of malaria was confirmed by thick and thin film with Giemsa staining of malaria parasite. Hematological parameters and serum levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), and bilirubin (total and direct) as test indicators of liver function were studied. Patients with parasitaemia tended to have significantly lower hemoglobin, hematocrit, white blood cell count, lymphocytes, and platelets, compared with healthy normal subjects. Neutrophils levels were significantly higher in cases of falciparum malaria in comparison to healthy normal subjects. Serums AST, ALT, ALP, and bilirubin (total and direct) in falciparum malaria patients were significantly higher (p < 0.0001) than those of falciparum malaria of free individuals. Hematological and liver dysfunctions measured parameters were seen associated with moderate and severe parasitaemia infection. This study concludes that hematological and hepatic dysfunction parameters could be indicator of malaria in endemic regions.
