Ninety-nine consecutive patients who received cytotoxic therapy for acute leukemia were retrospectively studied to determine the pattern of infection at the Tata Memorial Hospital, Bombay, India. In all, 224 infective episodes occurred in these patients. Bacterial infection was the commonest type, accounting for 152 (67.9%) of 224 infective episodes, followed by fungal and viral infections (15.6% and 14.3%, respectively). Gram-negative organisms (Pseudomonas and Klebsiella) were the commonest bacterial organisms isolated, constituting 38 (76%) of 50 positive cultures; infection with Staphylococcus was rare (10%). Infective hepatitis, malaria, and systemic tuberculosis were responsible for fever with neutropenia in 20, 4, and 2 patients, respectively. Three hundred fifty-two patients with lymphoproliferative malignancies were also retrospectively studied to determine the pattern of infection. Only 53 infective episodes were recorded. In these patients, in contrast to those with acute leukemia, viral infection (33 [62.3%] of 53) and pulmonary tuberculosis (18 [34%] of 53) were frequently seen. It is interesting that 50% of our patients with hairy cell leukemia also had tuberculosis. Bacterial infection was conspicuous by its absence. Knowledge of the prevailing pattern of infection permits the development of investigative and therapeutic approaches of optimal efficacy.

A 25-year-old male, who had returned from the Republic of Mali in Africa, was admitted to our hospital because of a 3-day history of high fever, on the first of October 1996. He was diagnosed as Plasmodium falciparum malaria by peripheral blood smear. From the admission day he was treated with quinine HCL, 1,500 mg per day, and sulfamethoxazole 2,400 mg trimethoprim 480 mg per day, but on October 2nd blood examination showed 35% parasite density and he was given mefloquine. However he was complicated with DIC on October 3rd, ARDS on October 5th. By anti-coagulant therapy and methylprednisolone pulse therapy he became afebrile and respiratory function improved rapidly. ARDS should be emphasized as a severe complication of imported severe malaria.

There are several clinical advantages of spleen targeting of nanocarriers. For example, enhanced splenic concentration of active agents could provide therapeutic benefits in spleen resident infections and hematological disorders including malaria, hairy cell leukemia, idiopathic thrombocytopenic purpura, and autoimmune hemolytic anemia. Furthermore, spleen delivery of immunosuppressant agents using splenotropic carriers may reduce the chances of allograft rejection in organ transplantation. Enhanced concentration of radiopharmaceuticals in the spleen may improve visualization of the organ, which could provide benefit in the diagnosis of splenic disorders. Unique anatomical features of the spleen including specialized microvasculature environment and slow blood circulation rate enable it an ideal drug delivery site. Because there is a difference in blood flow between spleen and liver, splenic delivery is inversely proportional to the hepatic uptake. It is therefore desirable engineering of nanocarriers, which, upon intravenous administration, can avoid uptake by hepatic Kupffer cells to enhance splenic localization. Stealth and non-spherical nanocarriers have shown enhanced splenic delivery of active agents by avoiding hepatic uptake. The present review details the research in the field of splenotropy. Formulation strategies to design splenotropic drug delivery systems are discussed. The review also highlights the clinical relevance of spleen targeting of nanocarriers and application in diagnostics.

Invasive Aspergillus tracheobronchitis is a relatively rare form of invasive pulmonary aspergillosis characterized by invasion of the tracheobronchial tree by Aspergillus spp. Invasive pulmonary aspergillosis is predominantly detected in severely immunocompromised patients. Notably however, pulmonary and tracheobronchial cases of invasive aspergillosis have also been reported, particularly in the context of severe malaria caused by Plasmodium falciparum. Herein, we present a case of invasive Aspergillus tracheobronchitis in a patient with hairy cell leukemia and previous Plasmodium falciparum infection.
