Rifampin, a broad-spectrum antibiotic able to penetrate intracellularly, was used for treatment of infections with Brucella melitensis in mice and Brucella abortus in guinea pigs. Treatments were administered for seven, 14, or 21 days; mice were given 25 mg of rifampin/kg per day, and guinea pigs 100 mg/kg per day. Efficacy of the drug was determined by comparison of rifampin-treated animals with saline-treated controls and with tetracycline-treated mice (200 mg/kg per day) according to the following criteria: (1) primary infections of the spleen and (in guinea pigs) of the lymph nodes; (2) residual infections of the spleen, i.e., infections shown after complementary treatment with suspensions of killed Corynebacterium parvum or with cortisone; (3) splenomegaly; and (4) serological response (in guinea pigs). Treatment with rifampin, even for one or two weeks, drastically reduced the number of infections by all of these criteris, and treatment for three weeks cured nearly all mice; the incidences of primary and residual infections in rifampin-treated mice after three weeks were 0 and 8.5%, respectively, as compared with 70.3% and 73.5%, respectively, in tetracycline-treated mice. Of 25 guinea pigs treated with rifampin for three weeks, spleen infection was shown in one, and lymph node infections in 10.

An 18-year-old Turkish farmer was admitted to the hospital because of fever, painful scrotal swelling, generalized lymph-node enlargement and splenomegaly. After an incubation period of six days Brucella melitensis was isolated in blood culture. The diagnosis of acute brucellosis with lymphadenopathy, splenomegaly and epididymitis was made. He was treated with doxycycline and Rifampicin for six weeks and recovered completely. Three months after therapy he felt well. A relapse did not occur.

Streptovaricins (Sv), ansa macrolide antibiotics, inhibited Rauscher leukemia virus (RLV) splenomegaly by 25-50%. All streptovaricins tested were effective when administered orally either by diet ad lib or by intubation from infection to time of killing. When delivered by intubation, Sv was measurable in plasma for up to 6 h. SvC, at 300 mg/kg/day, reduced mean spleen weight of infected mice from 478 plus or minus 51 (SE) mg to 300 plus or minus 55 (SE) mg. Rifampicin, at 250 mg/kg/day, had no similar activity. Decrease in caloric intake and in body-weight gain also resulted in an inhibition of RLV splenomegaly; although Sv-treated mice gained weight, the increase was usually slightly less than controls. However, mice treated with a Sv diet for a week prior to infection, after an initial period of weight loss, gained at a rate equivalent to control group, and when killed had a marked reduction in splenomegaly. The selectivity of streptovaricins and specificity for viral events was suggested by several observations: (1) Splenomegaly and mortality, induced by L1210 or a non-infective transplantable tumor of RLV origin, was not inhibited. (2) No inhibition of normal hematopoietic spleen colonies was observed. (3) Host immune responses, including cellular and humoral immunity and interferon production and action, were not inhibited. Thus, although the effect of slightly decreased weight and intake could not be unequivocally established, the findings were most compatible with a selective inhibition of RLV splenomegaly by Sv.

Splenic abscess is a rare clinical condition and yet rarer is a tubercular splenic abscess. Here we report a case of tubercular splenic abscess. A forty years old male patient was admitted in Medicine unit of Mymensingh Medical College Hospital (MMCH) on 09-08-2006 with the complaints of Left upper quadrant abdominal pain and fever for 15 days and Respiratory difficulty for 2 days. Two days after admission he developed generalized abdominal pain and distension. Pain was not associated with vomiting. Patient was transferred to surgical unit for features of peritonitis. Ultrasonogram of whole abdomen revealed moderately enlarged spleen showing 8.8 x 9.7 cm semicystic mass, which may represent an abscess. There was mild free fluid collection in the lower abdomen. X-ray chest P/A view showed bilateral pleural effusion. On laparotomy huge amount of free pus was found in the peritoneal cavity and the spleen was hugely enlarged with a burst abscess cavity in it. Splenectomy and thorough peritoneal toileting was done. Postoperative recovery was uneventful except few stitch infections. Pus culture revealed no growth but histopathology of spleen confirmed Tubercular Splenic Abscess. Patient was given an antitubercular regimen with Rifampicin, Isoniazid, Ethambutol and Pyrazinamide for initial two month which to be followed by Rifampicin and Isoniazid for another ten months.

Hemophagocyticlymphohistocytosis (HLH) is a proliferation of histiocytes with importanthemophagocytosisoccurring in different organs such as the spleen and the bone marrow. HLH is now increasingly diagnosed in the context of infections, malignancies and connective tissue diseases. Although brucellosis is an endemic infection in Tunisia, its association with HLH is a very rare condition which should be considered in patients with splenomegaly and cytopenia. Here, we describe brucellosis associated HLH in a 31 year-old man. The patient was admitted to our hospital with fever, sweating, and fatigue. Physical and laboratory findings revealed splenomegaly, pancytopenia, elevated serum transaminases, triglycerides, lactate dehydrogenase, and ferritin, and bone marrow hemophagocytosis. The Brucella agglutination test was positive. The patient improved after treatment with Rifampin and doxycyclin.
