Vibrio vulnificus infection with septicemia is a life threatening disease in the immunocompromised hosts. Renal involvement has not been documented. We reported herein 8 patients with V. vulnificus septicemia. All were immunocompromised hosts. Four patients had cirrhosis of the liver, 3 were heavy alcohol drinkers and one had systemic lupus erythematosis. Presenting symptomatology included fever, chills, leg pain and skin rash. Renal failure was observed in 6 patients. Four patients died shortly after admission. Two survived with clinical course of tubular necrosis. Renal failure is therefore common in V. vulnificus infection. This should be brought to attention, and vigorous antibiotic treatment is required. The disease may be confused with leptospirosis, scrub typhus, malaria and other forms of sepsis which also present with renal failure.

We report the clinical presentation and outcome of 299 Malawian children with non-typhoidal Salmonella (NTS) bacteraemia and no evidence of focal sepsis, admitted to Queen Elizabeth Central Hospital (QECH), Blantyre, over a 26-month period (February 1996-April 1998). A peak incidence during the rainy season was noted. Salmonella typhimurium (79%) and S. enteritidis (13%) were the commonest isolates. For children aged > 6 months, NTS bacteraemia was significantly associated with malarial parasitaemia (RR 1.5 [1.2, 2.2], P < 0.01) and with severe anaemia (RR 7.2 [3.4, 15.3], P < 0.0001), when compared to other common pathogens causing childhood bacteraemia. Clinical overlap with malaria and anaemia, and the presence of malarial parasitaemia on admission, may delay diagnosis. NTS bacteraemia was commonly diagnosed following blood transfusion. Resistance in vitro to ampicillin (79%), co-trimoxazole (72%) and gentamicin (55%) was very common, and was rare to chloramphenicol (0.3%) which is the antibiotic of choice for NTS sepsis at QECH. Overall mortality was high (23%). Young age and clinical HIV infection were risk factors for mortality. Recurrences of NTS bacteraemia following antibiotic therapy were common among children with clinical HIV infection.

Acute renal failure (ARF) associated with liver disease is a commonly encountered clinical problem of varied etiology and high mortality. We have prospectively analyzed patients with liver disease and ARF to determine the etiology, clinical spectrum, prognosis and factors affecting the outcome. Other than hepatorenal syndrome patients, out of 221 cases, 66 developed ARF secondary to various liver disease like cirrhosis (n = 29, mortality 8, risk factors-older age p < 0.01, grade III/IV encephalopathy p < 0.05), fulminant hepatic failure (n = 25, mortality 15, risk factor-prolonged prothrombin time p < 0.01), and obstructive jaundice (n = 12, mortality 7, risk factor-sepsis p < 0.01). In these three groups the factors leading to ARF were volume depletion (24), gastrointestinal bleed (28), sepsis (34), drugs (27) [aminoglycosides (9) and NSAID (18)] along with hyperbilirubinemia. Various types of ARF with contemporaneous liver injury were malaria (n = 37, mortality 15, risk factors-higher bilirubin p < 0.001, higher creatinine p < 0.05, anuria p < 0.05 and dialysis dependency p < 0.05), sepsis (n = 36, mortality 22, risk factors-age p < 0.001, higher bilirubin p < 0.01, oliguria p < 0.05), hypovolemia with ischemic hepatic injury (n = 14, mortality 5, risk factors-higher creatinine p < 0.05 and SGPT p < 0.01), acute pancreatitis (n = 12, mortality 4, risk factors-higher bilirubin p < 0.001, higher SGPT p < 0.01, dialysis dependency p < 0.05), rifampicin toxicity (n = 10, no mortality), paroxysmal nocturnal hemoglobinuria (n = 3, no mortality), CuSO4 poisoning (n = 3 mortality 2), post abortal (n = 11, mortality 6, risk factors higher creatinine p < 0.05 and SGPT p < 0.01), ARF following delivery including HELLP syndrome (n = 12, mortality 4, risk factors-higher bilirubin p < 0.01 and SGPT p < 0.01), and of uncertain etiology (n= 14 mortality 4). 133 patients (60.2%), required hemodialysis hemodialfiltration or peritoneal dialysis. ARF associated with liver disease is having high mortality (42.5%). Avoidance of dehydration, hypotension, nephrotoxic drugs and sepsis, with promote dialytic support are necessary to reduce mortality and morbidity.

Falciparum malaria remains a major killer in developing countries, particularly for African children. Moreover, France is the leading European country in term of incidence of imported malaria. Parasitized erythrocytes, which can form rosettes or auto-agglutinate, are sequestrated in the deep microvasculature and stick to activated endothelium by the mean of various receptors. Activation of T lymphocytes and macrophages induces secretion of proinflammatory cytokines, including tumour necrosis factor, which contributes to severe disease. However, the pathophysiology of coma remains poorly understood. In nonimmune adults, besides cerebral malaria, pictures of severe sepsis with shock, acute renal failure and respiratory distress syndrome are common. Although chemotherapy of malaria is challenged by the continuing evolution of antimalarial resistance, quinine remains the first-line drug for severe imported disease. In addition, early symptomatic management in the intensive care unit setting is of paramount importance. Prevention of severe imported malaria lays on prophylactic measures during travel, as well as adequate management of uncomplicated disease after return. In developing countries, early and adequate treatment of uncomplicated disease using cheap alternatives to classical compounds should contribute to "roll back" malaria, particularly in sub-Saharan Africa.

In the tropical north of Australia there are high rates of infections in Aboriginal children living in remote communities. In addition to the burden of respiratory infections, diarrhoeal disease and skin sepsis, there are high rates of acute rheumatic fever, outbreaks of poststreptococcal glomerulonephritis and gonococcal conjunctivitis, endemic trachoma and various intestinal parasites. A number of infections generally restricted to the tropics are also present and can cause disease in both indigenous and non-indigenous children. These include melioidosis, Murray Valley encephalitis and dengue on the east coast. With global warming, these infections may become more common and more widespread within Australia and the potential for establishment of introduced infections such as Japanese encephalitis and malaria may increase.

Reye's syndrome virtually disappeared from much of the world after the use of salicylate in febrile children was successfully discouraged. This severe sepsis-like disease was thought to be caused by a hypersensitivity to salicylates in children with mild viral infections, although no mechanism consistent with this proposal was ever established. Salicylate toxicity in African children has been noted to have many clinical features in common with severe falciparum malaria, including acidosis, altered consciousness, convulsions, and hypoglycaemia. Salicylates are widely available in various formulations in many African countries, and are commonly used for initial treatment of the symptoms that malaria shares with other diseases. There is now experimental evidence that salicylate increases and prolongs the activity of key elements along the signalling pathway through which interferon gamma generates inducible nitric oxide synthase (iNOS), and we have shown that iNOS is strongly expressed in fatal malaria and other acute fevers in African children. We further propose that, in areas where salicyaltes are still used to treat the symptoms of febrile illnesses in children, this mechanism could exacerbate potentially serious infectious diseases, including falciparum malaria. In contrast, the absence of salicylate use in children in some Pacific islands could contribute to the milder outcome of falciparum malaria than is observed in Africa. Widespread expression of iNOS has also been seen in the tissues of a patient with fatal clinically defined Reye's syndrome. This finding suggests that Reye's syndrome can be mediated through salicylate enhancement of iNOS expression, the initial trigger in this instance usually being a viral infection.

An increasing number of genetic association studies have implicated polymorphisms of cytokine genes as host genetic factors influencing susceptibility to infectious disease, primarily using a candidate gene approach based on knowledge of disease pathogenesis. The application and limitations of association studies are reviewed together with the impact of recent advances in single nucleotide polymorphism mapping on strategic approaches to defining genetic susceptibility loci. It often remains unclear whether associated genetic polymorphisms are themselves functionally relevant or acting only as markers within an extended haplotype, and experimental approaches to investigating the functional impact of polymorphisms in noncoding regulatory DNA sequences are discussed. An overview of genetic associations of cytokine genes with infectious disease is presented, together with discussion of recent studies in a number of infectious diseases including hepatitis, HIV, malaria, and sepsis.

Patients who lack a functioning spleen become vulnerable to sepsis caused by bacteria and, occasionally, protozoa. The risk is higher in children and in those who have had immunosuppressive treatment, and the risk remains lifelong. Overwhelming post-splenectomy infection (OPSI) occurs at an estimated incidence of 0.23-0.42% per year, with a lifetime risk of 5%. Episodes of OPSI are emergencies, requiring immediate parental antibiotics and intensive care; intravenous immunoglobulins may be useful. OPSI carries a mortality of 38-69%. Streptococcus pneumoniae is the commonest infecting organism, accounting for 50-90% of isolates from blood cultures in reported series; it is particularly common in children with sickle cell disease. Less commonly, the infecting organisms are other bacteria, Babesia or Ehrlichia. OPSI may be, to some extent, preventable by several interventions. These are surgical conservation of the spleen; immunization against S. pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis; prophylactic antibiotics; stand-by antibiotics; patient information sheets; and a medical alert bracelet. Asplenic patients living in malaria-endemic areas require optimal prophylaxis. The initial step in prevention of OPSI is the creation of an asplenia register, as many patients are not covered by these simple measures.

A study of 256 annual reports from 17 rural tropical hospitals in 4 African countries over a period of 16 years showed an absolute increase in the number of patients admitted with infectious diseases. Admissions were highest for malaria, followed by pneumonia and gastroenteritis. Admissions for immunisable diseases are decreasing in all countries. Fever remains the most important indicator of infectious diseases. Analysis of fever patients in rural tropical hospitals relies on knowledge of the epidemiology of diseases, plus expertise in physical examination. In this study, a detailed analysis of 900 fever patients indicated that 4% showed no infection, 21% of infections could be diagnosed by physical examination, 35% were diagnosed with the help of additional laboratory tests and 40% of patients were diagnosed as FUO (fever of unknown origin). 17% of FUO patients had a short, self limiting fever, but the remaining 23% were severely ill, suggesting bacterial sepsis, as was indicated by earlier studies. Undiagnosed fevers with resulting over-treatment and high resistance are costly and dangerous. These effects stress the need for better and more laboratory facilities, including possibilities for bacterial cultures. At present, patients are generally over-treated with antimalarials and antibiotics, since further diagnostic facilities are not available. Resistance is high for antimalatials ( Malaria) and for Amoxycillin, Cotrimoxazole and Gentamicin (Gram-bacteria from urine and blood).

An estimated 15 million children under 5 die each year, most of them in developing countries. Some 1/2 million women die of causes related to pregnancy, leaving at least 1 million children orphaned. The World Fertility Surveys of the 1970s demonstrated the direct relationship between family planning and maternal-child health. Between 1985-2000, some 2 billion children are expected to be born, 87% of them in developing countries. Some 240 million will die before 5 years. The main causes of death in small children are acute diarrheal disease, respiratory infections, transmissible diseases preventable with vaccination, malaria, malnutrition, and high fertility. 3 aspects of reproduction have significant effects on child survival: spacing, parity, and maternal age. In 1986, approximately 2 million children under 5 died because of risks associated with rapid procreation, and it is estimated that 1/5 of all child deaths could have been prevented with longer birth intervals. Maternal exhaustion and the inability to give adequate care to several small children at once are believed to be the main causes. The problem of abortion or fetal death increases significantly beginning at the 3rd birth, and the proportion of low birth weight babies increases at the 4th birth. The risk of malnutrition increases in large families with limited resources. The safest ages for childbearing are 20-34 years; the worldwide infant mortality rate for mothers under 20 is about 126/1000. Adolescent mothers are at increased risk of problems in the pregnancy and delivery. Family planning can reduce risks related to spacing, family size, and maternal age, and also risk of congenital defects that increase for older mothers. According to the World Health Organization, each year there are some 500,000 maternal deaths, only 6000 of which occur in developed countries. Immediate causes of maternal death in developing countries include hemorrhage, sepsis, eclampsia, dystocic delivery, and induced abortion, but the underlying causes are related to the poor situation of the woman: poverty, illiteracy, lack of adequate prenatal health care, and childbearing at extreme ages. Estimates based on the World Fertility Survey suggest that if all women stating they wanted no more children used contraception, 30% of maternal deaths would be avoided. It is estimated that some 15 million women undergo induced abortions each year, with 100,000-200,000 resulting deaths.
