Risk factors for endogenous endophthalmitis secondary to Klebsiella pneumoniae liver abscess.

BACKGROUND: To identify the risk factors for endogenous endophthalmitis secondary to Klebsiella pneumoniae (KP) liver abscess. METHODS: Retrospective chart review of 200 patients with KP liver abscess from 1990 to 2000 was performed. Data variables included age, sex, past history, systemic condition, initial and final visual acuity, slit lamp biomicroscopy, intraocular pressure, fundus, course and treatment. RESULTS: Extrahepatic metastasis developed in 44 patients, including 18 cases (23 eyes) of endophthalmitis. Seventeen eyes had final vision less than counting fingers. Diabetes had significant association with the development of extrahepatic metastasis (p = 0.045) and the poor visual outcome of endophthalmitis (p = 0.022), whereas, neither the initial vision nor vitrectomy was significantly related to the outcome of endophthalmitis. CONCLUSIONS: The visual prognosis of endogenous endophthalmitis secondary to KP liver abscess is generally poor, and diabetes might be a significant risk factor for the poor visual outcome. Even when the initial vision is as bad as light perception only, some eyes can be saved. Both internists and ophthalmologists should be alert enough to detect and treat these patients early.

Treatment of Toxoplasma brain abscess with clindamycin and sulfadiazine in an AIDS patient with concurrent atypical Pneumocystis carinii pneumonia.

Toxoplasmosis is the most common opportunistic infection of the central nervous system in patients with AIDS. The standard treatment for toxoplasmic encephalitis is pyrimethamine and sulfadiazine. There have been few reports of concurrent Toxoplasma brain abscess and cavitary Pneumocystis carinii pneumonia (PCP) in Taiwan. We report the case of a 26-year-old homosexual man with coexisting infection with Toxoplasma gondii and P. carinii who was successfully treated for brain abscess with clindamycin and sulfadiazine. The cavitary lung lesions, initially diagnosed as pulmonary tuberculosis, were proved to be PCP by lung biopsy. HIV infection and syphilis had been diagnosed 1 year before admission. He presented with general weakness, ataxia, nausea, blurred vision and fever for 2 weeks. Magnetic resonance imaging of the brain revealed multiple ring-enhanced lesions over the cerebrum and cerebellum. Chest roentgenography showed a 3-cm lesion with cavitation over the right upper lung field. Diagnostic computerized tomography-guided lung biopsy revealed P. carinii cysts. Clindamycin, sulfadiazine and trimethoprim (TMP)-sulfamethoxazole (20 mg/kg/day TMP) were given with good response. His CD4 count rose from 40 to 280/microL 4 months later. All antibiotics were discontinued after 4.5 months due to the development of a skin rash. He was well at follow-up 1 year later. This case suggests that the combination of clindamycin and sulfadiazine is an effective treatment for Toxoplasma brain abscess and highlights the importance of diagnostic lung biopsy for cavitary lung lesions, particularly in a region endemic for tuberculosis.
