For the last few years it has been known that high molecular weight circulating immune complexes containing IgM, other immunoglobulins and complement are usually present in TSS. Similar material to be found in the Kupffer cells of affected patients, and on the surfaces of their red cells. The recent demonstration that the immune complexes contain malarial antibody activity strengthens the belief that they also contain malarial antigen and are due to the basic immunological abnormality. As indicated in this review, further studies are required fully to confirm their role in the production of the splenomegaly, the auto-immune phenomena and the haemolysis of TSS. The balance of evidence favours a genetic rather than a purely environmental basis for development of the syndrome. Treatment is simple, inexpensive and relatively free of risk. It is feasible even in rural communities pending the advent of successful malaria eradication, the ultimate means of prevention and cure.

Serum immunoglobulin concentrations, malarial antibodies and schistosomal antibodies were measured in 33 patients with a provisional diagnosis of schistosomal splenomegaly, 16 with TSS of presumed malarial aetiology and in 52 controls. IgG and IgM were higher in both splenomegaly groups than in the controls and IgG was significantly higher in patients with schistosomal splenomegaly than in TSS. Although a very high IgM was found more often in the TSS group, there was no significant difference between the mean IgM levels in the two splenomegaly groups. The mean antischistosomal antibody titres were significantly higher in the schistosomal group than in those with TSS but there was no difference in the antimalarial antibody titres. These results emphasise the problems of diagnosis of gross splenomegaly in areas where schistosomiasis and malaria coexist.

Identification of the cause and subsequent specific therapy are indicated for those prolonged or relapsing fevers that follow abdominal surgery. On rare occasions, these fevers can be attributed to potentially life-threatening occult infections, including maxillary sinusitis, acute cholecystitis, antibiotic-related pseudomembranous colitis, toxic shock syndrome, systemic candidiasis, and transfusion-related cytomegalovirus disease, malaria, and babesiosis. Early recognition and appropriate treatment of these infections relieve anxiety, reduce hospital costs, and increase patient survival rates.

Serological investigations (immunoglobulin, haptoglobin, cryoglobulin, and antibody determination against Plasmodium falciparum and P. malariae antigens) were performed in 64 adults of the Albert-Schweitzer-Hospital, Lambarene, Gabon. The patients were referred consecutively for ultrasound examination of the upper abdominal tract. 31 patients had clinically and sonographically an enlarged spleen, whereas 34 had a normal-sized spleen. 18 patients were regarded as having a gross splenomegaly without an obvious underlying cause (tropical splenomegaly (TSS]. No significant differences were seen between the patient groups with regard to immunoglobulin M or antiplasmodial antibody concentration. Thus, a causal association of splenomegaly with chronic malaria infections could not be established. The haptoglobin levels were significantly (P less than 0.01) reduced in patients with splenomegaly. Peripheral T-lymphocyte subsets as defined by monoclonal antibodies showed in all 4 cases with gross splenomegaly examined distinct abnormalities. Tropical splenomegaly is thought to encompass a variety of diseases, most of them presenting an intermediate stage of reactive to autonome disorders of the lymphatic system.

The Department of Health and Human Services (DHHS) has played a critical lead role over the past two years in fostering activities associated with the medical and public health response to bioterrorism. Based on a charge from Secretary Donna Shalala in 1998, the Centers for Disease Control and Prevention (CDC) is leading public health efforts to strengthen the nation's capacity to detect and respond to a bioterrorist event. As a result of our efforts, federal, state, and local communities are improving their public health capacities to respond to these types of emergencies. For many of us in public health, developing plans and capacities to respond to acts of bioterrorism is an extension of our long-standing roles and responsibilities. These are stated in the CDC Mission Statement: to promote health and quality of life by preventing and controlling disease, injury, and disability, and the Bioterrorism Mission: to lead the public health effort in enhancing readiness to detect and respond to bioterrorism. CDC's infectious diseases control efforts are summarized below: --Initially formed to address malaria control in 1946; --Established the epidemic Intelligence Service in 1951; --Participated in global smallpox eradication and other immunization programs; --Estimated 800-1,000 + field investigations/year since late 1990s; --New diseases: Legionnaire's Disease, toxic shock syndrome, Lyme disease, HIV, hantavirus pulmonary syndrome, West Nile, etc. -- Today: focus on emerging infections and bioterrorism. Over the past 50 years, CDC has seen a decline in the incidence of some infectious diseases and an increase in some, whereas others continue to present on a more unpredictable basis (i.e., hantavirus). Outbreak identification, investigation, and control have been an integral part of what we do for more than 50 years. We estimate that 800 to 1,000 field investigations have occurred every year since the late 1990s. Today, however, we have a new focus on emerging infectious diseases and bioterrorism.

Fatal complications of Plasmodium falciparum malaria have been reported. However, complicated P. vivax malaria is rare. We observed two unusual cases of P. vivax malaria who presented with clinical pictures of toxic shock. Both showed disseminated intravascular coagulation with marked thrombocytopenia, oliguric renal failure, and pulmonary edema. Examination of initial blood smears showed a P. vivax parasitemia of 2,352/microL and 12,376/microL, respectively. The patients were treated with hydroxychloroquine and primaquine without an antibacterial agent. These cases emphasize the importance of considering the possibility of P. vivax malarial infection in patients with a clinical picture resembling toxic shock if they have a travel history to malaria-endemic areas.

Sepsis accounts for approximately 10% of all maternal deaths. Pregnant women are susceptible to certain infections because of alterations in their cell-mediated immunity. Obstetric sepsis requires early broad-spectrum antibiotic therapy and may necessitate surgical intervention. Group A streptococcal infection may produce necrotizing fasciitis and toxic shock. Pyelonephritis remains a common cause of sepsis during pregnancy, and associated acute respiratory distress syndrome occurs more commonly than in the nonpregnant population. Severe pneumonitis caused by influenza virus and varicella zoster infection may occur. Malaria may be more severe in the pregnant woman, and carries significant risk to both mother and fetus.

Seriously ill patients presenting with purpura fulminans, sepsis and multi-organ failure often require extensive diagnostic workup for proper diagnosis and management. Host of common infections prevalent in the tropics, e.g. malaria, dengue; other septicemic infections e.g. meningococcemia, typhoid, leptospirosis, toxic shock syndrome, scarlet fever, viral exanthems like measles, infectious mononucleosis, collagen vascular diseases (Kawasaki disease, other vasculitis) diseases, and adverse drug reactions are often kept in mind, and the index of suspicion for rickettsial illness is quite low. We present a case of Indian tick typhus presenting with purpura fulminans (retiform purpura all over the body), sepsis and multiorgan failure without lymphadenopathy and eschar, successfully treated with doxycycline and discharged home. Hence, a high index clinical suspicion and prompt administration of a simple therapy has led to successful recovery of the patient.
