Cellular immunity in typhoid fever, Legionnaires' disease, amebiasis: role of transfer factor and Levamisole in typhoid fever.

Typhoid fever is an infectious disease commonly seen in the tropics, with multisystem involvement and a high morbidity and mortality rate. Legionnaires' disease: a newly described acute respiratory infection by unusual aerobic gram-negative micro-organisms namely Legionella pneumophila. Cellular immunity: in vitro and in vivo evaluations of cellular immunity using E-rosette formation (E) and 2.4-Dinitrochlorobenzene (D) reaction were made in typhoid fever, amebiasis and Legionnaires' disease. Results will be presented. Three patients with relapsing typhoid fever were given transfer factor and another group with typhoid fever were given Levamisole with sulfamethoxazole-trimethoprim. Up to 90% of the cases receiving immunopotentiating factors/agents improved faster in both general condition, fever and cellular immunity.

[Hemophagocytic lymphohistiocytosis as a manifestation of visceral leishmaniasis].

A 7-year-old previously healthy Czech boy was admitted due to fever, hepatosplenomegaly and pancytopenia. Aspiration of bone marrow revealed no signs of hemoblastosis (nor hemophagocytosis). He was treated with antibiotics and virostatics without effect. Progression of hepatosplenomegaly and pancytopenia induced suspicion of hemophagocytic lymphohistiocytosis (HLH). Five weeks later, bone marrow hemophagocytosis of erythrocytes, nuclear elements and platelets was detected. He was given corticoids and intravenous immunoglobulins and transferred to our haematology department. Laboratory findings of mild pancytopenia, hypofibrinogenaemia, hyperlipidaemia and elevated levels of ferritin, LDH and immunoglobulins were compatible to the diagnosis of HLH. Immunologic evaluation revealed T-lymphocyte activation. Appropriate immunosuppressive treatment with Dexamethasone, etoposide and Cyclosporine A was launched, followed by transient subside of fever and improvement of peripheral blood count, but not regression of hepatosplenomegaly. Four weeks later, relapse of fever and deterioration of blood count led to intensification of immunosuppression. However, no effect was evident. Moreover, hypertrophic cardiomyopathy with ventricular arrhythmia occurred. Treatment with antilymphocytic globulin for resistant course of HLH was planned. Before that, a fifth bone marrow aspiration was performed. Surprisingly, many Leishmania amastigotes were observed within marrow macrophages. Leishmania infection was confirmed by positive serology. Immunosuppressive treatment was withdrawn and changed for causal treatment with liposomal Amphotericin B. Positive clinical effect with subside of fever was evident in ten days, splenomegaly gradually resolved during three weeks, restoration of normal blood count lasted six weeks. No relapses of HLH nor leishmaniasis occurred. In control bone marrow aspirate performed three months later, the parasites were not detected. Ten months after the event, the patient is in complete remission of HLH with normal immunologic parameters. Most probably, he contracted visceral leishmaniasis during a visit of a Neapol area in Italy 3 months before the onset of the disease.

Prolonged and secondary fever in childhood bacterial meningitis.

In order to study the causes of prolonged and secondary fever in bacterial meningitis, a group of 102 infants and children with proven bacterial meningitis were studied. The causative agent was Haemophilus influenzae in 58% of patients, Streptococcus pneumoniae in 25% and Neisseria meningitidis in 17%. Prolonged fever was observed in 12% of the patients. The established causes include, in order of frequency, subdural effusion, drug fever, otitis media, gastroenteritis and urinary tract infection. Secondary fever was noted in 18% of the patients. The causes, in order of frequency, were urinary tract infection, subdural effusion, otitis media, phlebitis, pneumonia and drug fever. Neither relapse of the meningitis nor inadequate response to antibiotic therapy was the cause for prolonged or secondary fever. Neurological sequalae were observed in 21 patients. There was no correlation between prolonged or secondary fever and neurological sequalae. We conclude that prolonged and secondary fever in patients with treated bacterial meningitis is rarely caused by the primary infection.

Relapse of rickettsial Mediterranean spotted fever and murine typhus after treatment with chloramphenicol.

In the years 1975-1984, 132 patients with rickettsial Mediterranean spotted fever and murine typhus were treated with chloramphenicol or tetracycline. Among the 24 patients who received chloramphenicol ten relapsed and one failed to respond at all. None of the 108 recipients of tetracycline suffered a relapse. It appears that tetracycline should serve as first-line therapy in several rickettsial diseases.

Recombinant human interleukin-10 fails to alter proinflammatory cytokine production or physiologic changes associated with the Jarisch-Herxheimer reaction.

Interleukin (IL)-10 may have a role in the treatment of cytokine-associated inflammatory syndromes. The Jarisch-Herxheimer reaction (J-HR), which follows antibiotic treatment of Borrelia recurrentis infection, is a useful model of acute systemic inflammation associated with a cytokine surge and characteristic pathophysiologic changes. In a double-blind, placebo-controlled study, 49 Ethiopian men with B. recurrentis infection were randomized to receive a single intravenous bolus of either 25 microg/kg of recombinant human (rh) IL-10 or vehicle control shortly before receiving intramuscular penicillin. Patients were monitored for physiologic changes, and plasma samples were taken repeatedly for 24 h after treatment. rhIL-10 had no impact on changes in any of the physiologic parameters of J-HR, plasma cytokine levels, or the rate of spirochete clearance. A single intravenous bolus of 25 microgram/kg of rhIL-10 does not seem to have a useful role in the treatment of the J-HR associated with B. recurrentis infection.
