CID 1996;23 (November) Brief Reports vicular tender mass with a diameter of 5-8 cm was noted, and there was a papulomacular erythematous skin lesion (1 cm in diameter) on top of the mass; tender small axillary lymph nodes were also found. The liver was palpable 5 cm subcostally. The results of laboratory investigations were as follows: erythrocyte sedimentation rate, 80 mm/h; C reactive protein, 60 mg/L; hemoglobin, 13.3 g/dL, WBC count, 15,900/mm 3 ; platelets, 664,000/mm 3 ; and alanine aminotransferase, 37 U/L. Serological investigations for HIV, cytomegalovirus, and hepatitis viruses A, B, and C as well as for Toxoplasma gondii were negative. IgM to EBV viral capsid antigen was detected. A CT scan revealed the supraclavicular lymph node, generalized abdominal lymphadenopathy with tumors of up to 3.6 cm in diameter, and slight enlargement of liver and spleen. Examination of biopsy specimens from the cervical tumor revealed pus, but cultures of these specimens were negative for bacteria and mycobacteria. Histological examination of the biopsy specimens showed necrotic granulomatous inflammation with giant cells; stains for acid-fast bacteria and argyrophilic bacilli were negative. Upon specific questioning, the patient remembered having played with a young cat some weeks before the onset of his present illness. CSD was considered in the patient's differential diagnosis. Serology performed as described in previous reports [3, 4] showed an IgG titer of antibodies to B. henselae of 1:2,048. B. henselaespecific DNA was detected in the tumor biopsy specimen by PCR with use of primers that allow the simultaneous amplification of B. henselae and Bartonella quintana followed by species-specific hybridization [2]. The patient was treated with clarithromycin (500 mg twice daily for 4 weeks), and he felt well afterwards. Six months later, an abdominal ultrasonogram still showed slight hepatosplenomegaly. IgM to EBV viral capsid antigen was no longer detected, and the titer of IgG to B. henselae was 1:512. IgG seroconversion to B. henselae and to nuclear antigen of EBV was documented. The first serum specimen (obtained 20 August 1994) revealed an already positive titer of IgG to EBV viral capsid antigen (table 1). This case emphasizes that CSD may be a severe systemic disease and demonstrates that generalized lymphadenopathy should be carefully investigated. EBV infection may have been reactivated by B. henselae or EBV may have promoted dissemination of B. henselae, which led to our patient's severe illness. Because of the lack of controlled therapeutic trials, it is not known whether antibiotic treatment of immunocompetent patients with CSD is Isolation of Candida norvegensis from Clinical Specimens: Four Case Reports In recent years, we have seen a greater number of previously unusual yeasts isolated from patient specimens; this circumstance corresponds to the increasing population of immunocompro- Reprints or correspondence: Dr. S.

Candida norvegensis was originally isolated in 1954 by Dietrichson [3a] and was later described by other investigators [4]. We searched the world literature and found a single case report of invasive diseak due to C. norvegensis [5]. We describe four seriously ill patients from whom C. norvegensis was isolated; two of these patients had AIDS. To our knowledge, C. norvegensis infection has not previously been reported among patients with AIDS. Patient 1. A 31-year-old HIV-infected man with a history of Pneumocystis carinii pneumonia (PCP) and Kaposi's sarcoma had oropharyngeal candidiasis (OPC), which was treated with fluconazole. He developed cytomegalovirus esophagitis and probable PCP when his CD4 cell count was 12 x 10 6/L. He had another episode of OPC that responded to fluconazole therapy, but his respiratory symptoms persisted, and C. norvegensis was isolated 1186 CID 1996; 23 (November) Brief Reports Table 1.

Two isolates were obtained from these patients. from his sputum on 12 December 1994 (table 1). His respiratory status deteriorated, and he died on 20 January 1995. Patient 2. An HIV-infected man with a history of severe cryptosporidial diarrhea, recurrent OPC, and cerebral toxoplasmosis developed worsening OPC that was unresponsive to treatment with oral fluconazole (150 mg daily). Culture of mouth washings yielded only C. norvegensis (table 1). The OPC did not respond to further oral treatment with fluconazole, itraconazole (200 mg daily), miconazole gel, or amphotericin (200 mg q.i.d.). The patient's condition deteriorated, and he died shortly thereafter. Patient 3. A 63-year-old female ex-smoker underwent laparoscopic cholecystectomy in 1993. She presented on 29 May 1994 with small-bowel obstruction, marked hypotension, and hypoxia while breathing room air. She was resuscitated with intravenous fluids and underwent laparotomy, at which time an adhesive mass and some dilated small bowel was resected. There was no evidence at this time that the bowel was perforated. A fever (temperature, 38.5°C) was noted. The patient was ventilated postoperatively, and treatment with intravenous broad-spectrum antibiotics was begun. She developed hypoxemia, and a chest radiograph showed diffuse bilateral shadowing, consistent with adult respiratory distress syndrome (ARDS). Therapy with high-dose iv hydrocortisone was started. Fast atrial fibrillation and recurrent pyrexia developed. C. norvegensis was isolated from catheter urine and sputum specimens (table 1). Ventilation of the patient remained difficult. No fungal blood cultures were done, and she received no systemic antifungal treatment. C. norvegensis was isolated again from the abdominal wound. Her respiratory function worsened, and she developed pneumothoraces and died on 17 June 1994. Postmortem examination revealed scattered foci of bronchopneumonic consolidation with areas of edematous tissue, consistent with ARDS. The tissue was not examined microscopically. Patient 4. A 65-year-old man had undergone right nephrectomy for renal cell carcinoma and had had a myocardial infarction in 1993. He was admitted to the hospital for evaluation of melena on 19 January 1995. He continued to bleed, and Polya's operation was performed, followed by a second laparotomy for postoperative bleeding. An abdominal CT scan showed probable metastases from a bronchogenic primary lesion. Culture of a throat swab yielded C. norvegensis. Despite further treatment, the patient's condition deteriorated, and he died 9 days after surgery. C. norvegensis isolates were identified for production of pseudohyphae with use of the ID 32C strip (bioMerieux, Marcy l'Etoile, France) and rice-agar-tween medium (bioMerieux). C. norvegensis appears as long oval-to-cylindrical cells that are 2-8 p,m by 5-13 tim after 3 days of growth at 25°C in glucose-yeast extractpeptone water [4]. The cases of the patients described herein do not provide unequivocal evidence of the inherent pathogenicity of C. norvegensis, although this pathogenicity is likely in cases 2 and 3. The common factors (i.e., that all four patients had severe, ultimately fatal underlying conditions and that all were receiving antibiotics) characterize the clinical setting in which this unusual Candida species may be isolated from patients. There are few previous reports of the isolation of C. norvegensis from human specimens. Nielsen et al. [5] reported a similar clinical scenario in which C. norvegensis was cultured in peritoneal fluid from a patient receiving immunosuppresive therapy who was undergoing continuous ambulatory peritoneal dialysis. The patient developed a large gastrointestinal hemorrhage secondary to a perforated duodenal ulcer and subsequently died. The only other published report of C. norvegensis infection cites this case [5] and one other case in which fungemia occurred and two isolates were recovered from urine specimens, with no further clinical details given [8]. The susceptibility test results for our isolates support other evidence that C. norvegensis is a species with a degree of inherent antifungal resistance [9]. All of these isolates were resistant to fluconazole, and two were recovered from patients who had had no previous exposure to any azole. Our method of testing fluconazole susceptibility yields results that correlate with clinical outcome in the context of OPC in patients with AIDS [6, 10] as is demonstrated by case 2. Yeast identification and susceptibility testing are likely to be increasingly helpful in Brief Reports CID 1996;23 (November) patient care given the increasing number of unusual fungi now being recovered.

Hypothermia Following the Intravenous Administration of Amphotericin B We describe a case of severe hypothermia following the intravenous administration of amphotericin B; we believe this is a previously unreported adverse drug reaction. A 41-year-old, HIV-infected male (CD4 cell count, 6/mm 3 ) was admitted to the hospital with a 2-4-day history of fevers, diarrhea, nausea, vomiting, and chills. Physical examination revealed a temperature of 39.2°C, blood pressure of 100/62 mm Hg, and heart rate of 91. No infiltrates were seen on a chest radiograph, and all other laboratory values were within normal limits. Sputum, urine, blood, and stool were cultured. Empirical treatment with intravenous antibiotics was started and consisted of vancomycin, ceftizoxime, and fluconazole. Medications on admission included chlorhexidine gluconate, fluconazole, ethinyl estradiol, conjugated estrogens, medroxyprogesterone, beclomethasone metered dose inhaler, meclizine, omeprazole, and acetaminophen. From hospital day 1 through 5, the patient remained febrile, and cultures were negative. Repeated blood cultures on hospital day 6 were positive for Histoplasma capsulatum. Empirical antibiotic therapy was discontinued, and treatment with peripherally administered intravenous amphotericin B (0.8 mg/ [kg • d]; 50 mg of amphotericin B in 500 mL of 5% dextrose in water with 25 mg of hydrocortisone to be infused over 4 hours) was started. The patient was premedicated with hydrocortisone and acetaminophen 2 hours before infusion. Vital Reprints or correspondence: Dr. Theodore G.

Within 30 minutes, the patient's temperature declined to 35.5°C, and the infusion was discontinued 1 hour later. A total of 20 mg of amphotericin B had been administered when the patient's temperature was noted to be 34.5°C (figure 1). Six hours after the infusion was initiated, the patient's temperature had continued to decline to 32°C, his blood pressure was 140/90 mm Hg, and his pulse rate was 48. A heating blanket was applied. A cortisol stimulation test demonstrated normal adrenal function. An electrocardiogram was remarkable for inverted T waves, consistent with hypothermia. The patient's temperature gradually increased over the next 30 hours to 36.6°C. Treatment with amphotericin B was discontinued, and oral itraconazole therapy (200 mg t.i.d.) was initiated. Over the next several days, the patient's condition continued to deteriorate. Treatment with itraconazole was subsequently discontinued, and amphotericin B was readministered, as described earlier, on hospital day 9. Hydrocortisone, acetaminophen, and diphenhydramine were administered 1 hour before the infusion. The patient's rectal temperature was initially noted to be 40.6°C (figure 1). Six hours and 11 hours after the infusion was initiated, the patient's oral temperature had decreased to 36.7°C and 35.1°C, respectively. Despite aggressive treatment, the patient died on hospital day 11. During more than 40 years of experience with amphotericin B therapy, this is the first time that hypothermia has been associated with use of this drug. Following the first infusion of amphotericin B, the patient's temperature decreased a total of 5°C within 6 hours and did not increase until a heating blanket was applied. On readministration of amphotericin B, the patient's temperature again decreased, this time by 5.5°C. The rechallenge with amphotericin B and the subsequent reoccurrence of the adverse event strongly suggest that amphotericin B was responsible for the hypothermia. Although not well understood, adverse drug reactions and hypersensitivity reactions are more common in HIV-infected
