A primary HIV infection presenting as an acute viral syndrome in 31-years-old male drug addict is described. Two weeks after the probable infection the patient presented with fever, sweats, anorexia, vomiting, diarrhoea, myalgia, arthralgia, headaches, macular eruption, generalized lymphadenopathy, paresthesia and thrombocytopenia. These symptoms lasted 7 weeks. The immune abnormalities included an increase of CD8+ lymphocyte percentage resulting in decrease od CD4/CD8 ratio. HIV antigenemia was found 4 weeks after the presumed exposure whereas anti-HIV became detectable 2 weeks later.

Preclinical and clinical studies have demonstrated the effectiveness of granisetron in preventing emesis induced by antineoplastic chemotherapy. This comparative study was undertaken to investigate the efficacy and safety of granisetron (40 micrograms/kg) and granisetron plus methylprednisolone (MPL; 10 mg/kg). Sixty-eight patients were given granisetron 170 times and thirty-nine patients were given a combination of granisetron and MPL 81 times. Sixty-one patients received the treatment in crossover fashion during the same chemotherapy regimens. The emetic and nausea episodes were counted during the 24 hours following each chemotherapy treatment. Complete response, no emesis or less than two episodes, were obtained in 75.3% (128/170 times) of patients receiving granisetron alone compared to 85.2% (69/81 times) of patients receiving the combination of granisetron plus MPL. There were no significant differences in complete responses between the two groups, male and female, and each age group. However, 11 of eighteen patients receiving granisetron alone who responded mildly, if at all, with respect to nausea and vomiting, showed a complete or major response when MPL was added to granisetron. There were two patients who developed temporal paresthesia of the both hands as an adverse effect, but there was spontaneous recovery after 3 hours. Our data suggested that granisetron plus MPL was slightly more effective than granisetron alone and a safe antiemetic drug.

Clinical data on the first 100 patients who underwent dipyridamole-thallium stress testing in our hospital were reviewed in order to re-evaluate safety guidelines and diagnostic utility in patients with coronary artery disease. Forty patients developed symptoms, including three major ones. One patient had significant bronchospasm, and two others developed significant hypotension with near syncope. The rest had nonspecific chest, shoulder, arm or throat pain, dyspnea, nausea, vomiting, and paresthesia. Most symptoms occurred within the first 10 minutes of dipyridamole infusion. Twenty-eight patients required treatment with intravenous (IV) aminophylline. Of the remaining 60 patients, 30 became hypotensive but remained asymptomatic. Fourteen of 20 patients who underwent coronary angiography had coronary disease. Thirteen were correctly identified by thallium imaging, and only one was identified by electrocardiogram (EKG). Six patients' angiographies showed no evidence of coronary disease. Five of these patients developed perfusion abnormalities during thallium scintigraphy. These results suggest that dipyridamole is a relatively safe drug for pharmacologic stress testing even though the incidence of side effects is relatively high. The high incidence of thallium perfusion abnormalities in patients without coronary disease probably reflects bias in patient selection for coronary angiography, resulting in a relatively small sample of catheterized patients. However, this requires further investigation.

Forty-two patients affected by either stage III and IV ovarian cancer with residual tumor after surgery or recurrent ovarian cancer entered a phase II study of the combination carboplatin 300 mg/m2 and cyclophosphamide 600 mg/m2 every 28 days. Thirty-eight patients were evaluable for response and of these 27 obtained complete or partial remission with a 71% overall remission (clinical complete remission 45%; partial remission 26%). Treatment tolerability was on the whole good. The most frequent side effects were leukopenia (76%), anemia (67%) and nausea/vomiting (60%). Thrombocytopenia was present in 31% of the patients, but nearly always to a mild degree except for one grade 4 case. No other grade 4 side effect was observed. We did not observe any cases of nephrotoxicity and only two patients complained of paresthesia. This carboplatin-cyclophosphamide combination in advanced ovarian carcinoma produces comparable results, in terms of objective responses, to those obtained with standard cisplatin-based regimens, with suggestion of a better toxicological profile.

Ninety-two adult patients scheduled for automated percutaneous discectomy (PERC) were assigned to receive either local anesthesia supplemented with monitored i.v. analgesia (MIVA) or general endotracheal anesthesia (GA-LITE). Patients were examined 1 week post-PERC for the presence of new paresthesias, and they completed a questionnaire 6-18 weeks after PERC about changes in their pain. Sixty-four percent of MIVA patients and 83% of GA-LITE patients had diminished pain following PERC. Results did not show any difference between the two groups for new paresthesias after PERC. There were no differences in postoperative pain medication requirements, but the GA-LITE group reported more postoperative nausea, vomiting, and sore throat. GA-LITE patients averaged 1.06 +/- 0.3 h in the recovery room compared with 0.70 +/- 0.3 h for MIVA patients. Although the use of general anesthesia for PERC has been contraindicated because of fear of damaging the nerve root in the sleeping patient, we conclude that general anesthesia does not increase nerve injuries attributable to instrumentation. However, general anesthesia did cause a higher incidence of minor complications such as nausea, vomiting, and sore throat in the immediate postoperative period than did MIVA.

Since the discovery of the biologically active platinum complexes 30 years ago, 2 agents have become widely established in clinical oncology practice. Both cisplatin and carboplatin are platinum(II) complexes with 2 ammonia groups in the cis- position. However, they differ in their solubility, chemical reactivity, dichloride or alicyclic oxygenated leaving groups, pharmacokinetics and toxicology. Cisplatin causes severe renal tubular damage and reduces glomerular filtration, and requires concurrent saline hydration and mannitol diuresis to eliminate potentially lethal and unacceptable damage to the kidneys. Carboplatin, at conventional doses, causes no decrease in glomerular filtration and only minor transient elevations in urinary enzymes. Cisplatin is the most emetic cancer drug in common use, while nausea and vomiting associated with carboplatin are moderately severe. Serotonin release from enterochromaffin gut mucosal cells and stimulation of serotonin 5-HT3-receptors mediates acute emesis. Selective inhibitors of the 5-HT3-receptor protect against cisplatin- and carboplatin-induced nausea and vomiting. Peripheral neurotoxicity is the most dose-limiting problem associated with cisplatin. Loss of vibration sense, paraesthesia and sensory ataxia comes on after several treatment cycles. Carboplatin, however, is relatively free from peripheral neurotoxicity. Audiometry shows cisplatin-induced ototoxicity in 75 to 100% of patients, which may be associated with tinnitus and hearing loss. Ototoxicity is rare with conventional dose carboplatin therapy. Monitoring hearing with audiograms may identify early signs before significant impairment occurs. Cisplatin causes mild haematological toxicity to all 3 blood lineages. Haematological toxicity is dose-limiting for carboplatin, with thrombocytopenia being a greater problem than leucopenia. Although carboplatin is not toxic to the kidney, renal function markedly affects the severity of carboplatin-induced thrombocytopenia. The major clearance mechanism of cisplatin is irreversible binding in plasma and tissues, while carboplatin is cleared by glomerular filtration. Metabolism of cisplatin to aqua, amino acid and protein species is extensive, whereas carboplatin exists mainly as the free unchanged form. Strong relationships between carboplatin renal clearance, glomerular filtration rate, area under the plasma concentration-time curve (AUC) of filterable platinum and severity of thrombocytopenia have prompted dose adjustment according to renal function. New analogues such as JM216 offer the potential advantages of oral administration and few nonhaematological toxicities. Analogues based on the diaminocyclohexane ligand have encountered problematic neurotoxicity.

The activity of single-agent paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been documented in untreated and previously treated metastatic breast cancer, including both patients with anthracycline-resistant disease and those with extensive pretreatment. Such activity has prompted investigations of the optimal doses and schedules of paclitaxel/doxorubicin combinations. With one exception, paclitaxel has been administered as either a 24- or a 3-hour infusion, while the administration times for doxorubicin vary from bolus injection to 72-hour infusion. Results of these completed phase I and II trials are reviewed. Also reported are two European trials that have achieved promising results. In Milan, a phase I/II trial has shown a preliminary response rate exceeding 90% in 32 chemotherapy-naive patients treated with an alternating schedule of paclitaxel given over 3 hours and intravenous bolus doxorubicin. At doses of paclitaxel 200 mg/m2 and doxorubicin 60 mg/m2, the dose-limiting toxicities were neutropenia, oral mucositis, myalgias, and peripheral neuropathy. Congestive heart failure occurred in six patients. A phase I/II study of a 30-minute doxorubicin infusion preceding a 3-hour paclitaxel infusion every 3 weeks in minimally pretreated patients also is reported. Of 29 patients evaluable for response, 17 have achieved partial responses and seven complete responses, for an overall response rate of 83% (95% confidence interval, 79% to 99%). Toxicities observed were grades 3 to 4 neutropenia and moderate paresthesias, nausea/vomiting, alopecia, myalgia, and mucositis. Cardiotoxicity also occurred, as 15 patients had a significant decrease in left ventricular ejection fraction measured by isotope cardiography. Six of these developed congestive heart failure. This effect has been observed only in studies using short infusions of both drugs, and it is now being investigated whether lowering the peak doxorubicin concentration will preclude it.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is an effective drug in the treatment of metastatic breast cancer (MBC). In the salvage setting, 5-fluorouracil (5-FU) and folinic acid have proved to be effective against MBC as well. Recent preclinical data suggest that paclitaxel plus 5-FU has additive cytotoxicity. Given these observations, we initiated a phase II trial in which 38 women with MBC have been treated with a combination of all three drugs. All patients are currently evaluable for toxicity and 34 are evaluable for response. All women had histologically proven and assessable disease. Patients with prior exposure to paclitaxel were ineligible. Patient characteristics include a median age of 51 years (age range, 31 to 73 years) and a median performance status of 1 (range, 0 to 2). Thirty-three patients have received prior chemotherapy, of whom 23 had adjuvant chemotherapy only. Fifty-eight percent of the patients (22 of 38) had received prior doxorubicin or mitoxantrone; four patients had only hormonal therapy. Four patients had bone-only disease, and three patients had lymphangitic spread or cytologically positive pleural effusion as the only evaluable disease. Treatment consisted of paclitaxel 175 mg/m2 over 3 hours (day 1 only), followed by folinic acid 300 mg over 1 hour, followed by 5-FU 350 mg/m2 on days 1 to 3. Patients received standard paclitaxel premedications. To date, 175 cycles have been administered (median cycle length, 29 days; median number of cycles per patient, five). Toxicities included grade 3/4 infections in nine cycles (5%), grade 3/4 mucositis in three cycles, grade 3/4 nausea/vomiting in three cycles, grade 1 paresthesias in 12 patients (32%), alopecia 100%, and 17 cycles (10%) associated with dose reduction. Based on Cancer and Leukemia Group B toxicity criteria, arthralgia/myalgias were modest and graded mild (32 cycles), moderate (nine cycles), or severe (two cycles). There were two major hypersensitivity reactions, prompting removal of those patients from further protocol treatment. Four patients are unassessable for response due to hypersensitivity reactions (two) and unevaluable disease (two). Among the 34 patients evaluable for response, there were three complete responses, 18 partial responses, one minor response, nine stable disease, and three progressive disease (response rate, 62%). Responses were seen in patients who had received prior doxorubicin or mitoxantrone (11 of 22 patients) and in anthracycline/naive patients (10 of 16 patients). Responses were observed in all metastatic sites: soft tissue, viscera, and bone. Paclitaxel/5-FU/folinic acid appears to be an effective and well-tolerated outpatient regimen for women with MBC, even after failure of anthracycline-containing therapy.

Desmopressin is a commonly used, well-tolerated agent for the treatment of primary nocturnal enuresis and central diabetes insipidus. Intranasal desmopressin provides symptomatic relief with few serious complications. A 29-year-old woman with a long history of primary nocturnal enuresis began treatment with intranasal desmopressin. Although the enuresis ceased, she developed throbbing headaches, nausea, vomiting, paresthesia, lethargy, fatigue, and altered mental status over the next 7 days. When she came to the emergency room her sodium concentration was 127 mmol/L. The history of desmopressin use was not obtained at that time. She was treated with intravenous fluids and discharged. The symptoms returned and worsened over the next 4 days, and she returned to the emergency room stuporous. A repeat sodium was 124 mmol/L, and she was admitted. The history of desmopressin use was still not available. Medical evaluations included computerized tomography, lumbar puncture, complete blood counts, serum chemistries, and serologies. The next morning the woman was improved and informed clinicians of her desmopressin use. Without other causes for the hyponatremia, she was diagnosed with the syndrome of inappropriate antidiuretic hormone, presumably caused by desmopressin. Within 24 hours of fluid restriction and cessation of desmopressin, her symptoms and hyponatremia resolved. A review of the literature found 11 children and 2 adults in whom intranasal desmopressin was associated with hyponatremia, all of whom experienced seizures or altered mental status. Our patient illustrates the importance of early recognition and treatment of hyponatremia before the onset of seizures. When vague symptoms develop during desmopressin therapy, hyponatremia must be considered as part of the differential diagnosis. It may also be prudent to screen for electrolyte abnormalities in patients taking this agent to prevent serious iatrogenic complications.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is active against advanced breast cancer and anthracycline-resistant breast cancer. We assessed the efficacy and toxicity of doxorubicin followed by a 3-hour infusion of paclitaxel in women with advanced breast cancer. Participants could have received at most one prior adjuvant chemotherapy regimen, but no previous exposure to anthracyclines or taxanes was permitted. The patients were treated every 3 weeks with doxorubicin (50 or 60 mg/m2) followed 30 minutes later by paclitaxel (155, 175, or 200 mg/m2). After reaching the maximum cumulative doxorubicin dose, treatment could be continued with paclitaxel alone. Thirty women were included, of whom 29 were evaluable for response. The overall response rate was 83% (95% confidence interval, 64% to 94%), with 24% of patients attaining complete remission. Median response duration for complete responders was 8+ months (range, 4 to 13 months) and median time to progression was 9 months (range, 2 to 18 months). Main toxicities were neutropenia, paresthesia, nausea/vomiting, alopecia, myalgia, and cardiotoxicity. In 15 patients (50%), the left ventricular ejection fraction decreased to below normal levels; six patients (20%) developed congestive heart failure. In conclusion, the combination of doxorubicin and paclitaxel is highly active; dose-limiting toxicities are neutropenia, neuropathy, and cumulative cardiotoxicity.
