To evaluate the consequences of receiving human immunodeficiency virus type 1 (HIV-1)-seropositive blood, 90 HIV-1-seronegative recipients of HIV-1-seropositive blood (case patients) and 90 HIV-1-seronegative recipients of HIV-1-seronegative blood, matched for age, sex, number of transfusions, diagnosis, and severity of illness (controls), were followed for 12 months after transfusion at Mama Yemo Hospital in Kinshasa, Zaire. Of case patients and controls, 72% were children transfused for anemia caused by malaria. Of the 46 case patients case patients alive 6 months after transfusion and for whom HIV-1 serologic results were obtained, 44 (96%) had seroconverted. Significantly more case patients (47%) than controls (16%) died within 1 year after transfusion (P less than .001). In the first 3 months after transfusion, fatigue, diarrhea, fever, cough, pruritus, pallor, oral candidiasis, polyadenopathy, hepatosplenomegaly, and rhinorrhea were observed more often among seroconverters than controls (P less than .04). Six percent of case patients and no controls had developed clinical AIDS after 12 months of follow-up. These findings underscore the urgent need for appropriate HIV screening facilities in transfusion centers worldwide.

The 11 cases of malaria admitted to Kaohsiung Medical College Hospital in the past 10 years were analyzed to assess the characteristics of patients who acquired malaria parasite infection. Nine of the patients contracted malaria in Southeast Asia. Two men had received antimalarial chemoprophylaxis before they went abroad and another two men relapsed after antimalarial treatment. The initial symptoms and signs were nonspecific, including fever, chills, abdominal pain and hepatosplenomegaly. Seven patients responded well to the antimalarial regimens. Two persons developed meningeal malaria. Resistance to chloroquine and primaquine and even to quinine was noted in another two cases. Hypoglycemia was diagnosed in one of latter two patients who developed heavy parasitemia (26%), acute renal failure and died 5 days after treatment. Peripheral blood smear examination is a simple and quick method to make a diagnosis in any suspicious case. Resistance to chloroquine and primaquine is not uncommon, especially in those who acquired the infection in Southeast Asia. Changing to more potent agents and aggressive management in complicated cases is necessary.

In a prospective, hospital-based study in North India, malaria accounted for 1.5% of paediatric outpatient attendances during 1 year. A marked increase in the prevalence of malaria was noted during the post-monsoon months. Plasmodium falciparum was the causative species in 44.4% of cases, contrary to previous reports of low prevalence of this parasite in the area. Pyrexia with or without chills or rigor, vomiting, pallor and hepatosplenomegaly were the common presenting clinical features. Splenic and hepatic enlargement were seen more frequently with P. vivax than P. falciparum infections (P less than 0.001 and P less than 0.01, respectively). Convulsions were present in 20% of cases.

Thirty-two patients of smear positive Plasmodium falciparum malaria having jaundice were analysed retrospectively. Majority of the cases were in the age group of 31-40 years. Serum bilirubin levels ranged from 2 mg to 40 mg%. Fourteen (42.6%) had serum bilirubin above 10 mg%. Conjugated bilirubinaemia was found in twenty one patients (65.5%), unconjugated in 4 (12.5%) while 7 patients (21.8%) had a mixed pattern. Serum transaminases were high in 21.8% patients. Twenty five patients (78%) had associated azotaemia, 11(34.3%) had intravascular haemolysis and 3(9.3%) had possible cerebral malaria. Hepatosplenomegaly was seen in all the 32 patients. Mortality was 21% but none died of hepatic encephalopathy. Histologically the most consistent finding in liver biopsies was reticulo-endothelial cell hyperplasia. Pigmentation in kupffer cells, fatty change, sinusoidal and portal infiltration and cholestasis were the other features seen.

Some 200 cases of malaria are officially reported yearly in Switzerland. It is estimated that 2000-8000 Swiss travellers are infected by the anopheles mosquito annually, with 90% protected by chemoprophylaxis. An attack of malaria appears to have a better prognosis when the symptoms start in Africa, since treatment is initiated immediately, than in industrialized countries where the mortality is 1-4%. Failure to inquire into travel history is often responsible for the delay in initiating treatment. Severe falciparum malaria is treated by repeated slow quinine infusions followed by 1500 mg sulfadoxine, 75 mg pyrimethamine and 750 mg mefloquine (single dose). This adult dose corresponds to 3 tablets of Lariam and 3 of Fansidar (or 3 of Fansimef). The increase in chloroquine resistance among falciparum strains has led to the use of Fansidar for chemoprophylaxis, followed by the use of mefloquine when Fansidar resistance occurs. The dosage of mefloquine is 250 mg weekly (1 tablet Lariam) for 4 weeks, followed by 1 tablet every fortnight. Treatment is continued for 1 month after return. If the risk of transmission is low, chemoprophylaxis may be replaced by prescription of a reserve drug to be taken in case of fever and headache. A sulfadoxine-pyrimethamine-mefloquine combination (i.e. 3 tablets Fansimef) has been tested in this indication. Ineffective chemoprophylaxis may lead to atypical clinical syndromes, e.g. anemia, hepatosplenomegaly and jaundice, without episodes of fever. HIV positive subjects may risk travelling in tropical countries if they have undergone correct chemoprophylaxis.

Fatal cases of experimental Plasmodium falciparum (Indochina I) in Bolivian squirrel monkeys (Saimiri sciureus boliviensis) were examined by histologic and ultrastructural methods. Gross lesions were characterized by hepatosplenomegaly and interstitial pulmonary changes. Histologically, there was marked diffuse reticuloendothelial hyperplasia, pulmonary alveolar septal thickening, mesangioproliferative glomerulonephropathy, sequestration of parasitized erythrocytes in deep vascular beds, degenerative parenchymal changes in the liver and myocardium, and in one case retinal and cerebral hemorrhage. These data indicate that the Bolivian squirrel monkey is a good model for studying pathologic changes associated with human falciparum malaria.

Acute clinical malaria caused by Plasmodium inui was diagnosed in an adult female cynomolgus monkey (Macaca fascicularis) 4 years after importation into the United States. Stress and immunosuppression associated with experimentation completed 2 weeks earlier may have contributed to the development of severe clinical disease. Clinical findings included severe regenerative anemia, hepatosplenomegaly, weakness, lethargy, weight loss, and anorexia. The infection was treated and successfully eliminated with chloroquine hydrochloride administered intramuscularly at a dose of 5 mg/kg base given at 0, 6, 24, 48, and 72 hours. Treatment also included a blood transfusion and intensive supportive care.

Malaria manifested during the first few months of life may be result of acquisition during pregnancy, at the time of delivery, or by mosquito bite after birth. Both congenital and perinatal malaria are acquired by the transmission of parasitized maternal erythrocytes across the placenta. An infant is described whose mother was diagnosed to have malaria at six months of gestation. The infant developed intermittent fever at 5 weeks of age and presented with anemia and hepatosplenomegaly at 3 months of age at which time Plasmodium falciparum parasites were found on examination of thick smears of the infant's blood. IgG and IgM antimalarial antibodies were detected in maternal blood, but only IgG antibodies were found in the infant's blood at delivery and at the time of diagnosis. These transplacentally transmitted antibodies may afford transient protection for the infant and thus delay the onset of clinical manifestations. Due to the absence of an exoerythrocytic life cycle in congenitally acquired malaria, chloroquine is the drug of choice for treatment. Infections with chloroquine-resistant strains require multiple drug therapy.

Clinical analysis of 293 cases of cirrhosis from two moderate sized hospitals in the city of Dacca has been presented. Maximum number of cases were in the age group over 40 with 150 (51.2%) males and 19 (5.8%) females. Significant past history included viral hepatitis (21.5%), kala-azar (11.6%) and malaria (10.24%). History of alcoholism was present only in 16 (5.5%) cases. Weakness (84.3%), weight loss (72%) and anorexia (39.3%) constituted the most common symptoms. Ascites (45%), haematemesis (11.6%) and melaena (28.7%) were the next common symptoms. Hepatosplenomegaly was found in about one-third of the cases. Testicular atrophy was recorded in 41.63% cases whereas gynaecomastia was relatively less common (5.5%). Scanty body hair and white nails were present in almost equal number of cases (14.7% and 18%). The cases presented here are those with overt manifestation. Nevertheless, the clinical features are not materially different from those reported by other authors. In the absence of alcoholism, viral hepatitis is presumably the most important aetiological factor in our cases and the clinical features compare favourably with non-alcoholic cirrhosis of the western writers. Cryptogenic cirrhosis has been considered to be most common type constituting 43.7% of our cases.

Cryptic/sporadic malaria is rare in the United States. We describe a patient who developed malaria in New York City without any known contact with, or travel to, a malaria-endemic area. The patient presented with symptoms of gastroenteritis. Later, she developed hemolysis and hepatosplenomegaly, and Plasmodium falciparum was found in blood smears. Possible sources of malaria could be an indigenous infected mosquito or a transported infected mosquito from a local international airport.
