Carboplatin, a new platinum analogue, was administered intravenously on a schedule of a single dose every five weeks to 23 patients with advanced malignant solid tumors. Patients were treated at six dosage levels ranging from 200-550 mg/m2 every five weeks. Thrombocytopenia was dose-limiting. At 550 mg/m2 Carboplatin, the median platelet nadir was 65 000/mm3. Leukopenia was common, but usually of mild to moderate degree. Gastrointestinal upset was commonly seen at all dose levels, but 35% of the patients experienced no vomiting. No significant increase of the serum creatinine following Carboplatin was seen. In 16 patients serial determinations of the creatinine clearance were performed. The median base line creatinine clearance was 87 (50-155) ml/min and dropped to a median lowest creatinine clearance of 69 (23-171) ml/min on day four (p less than 0.05). The median creatinine clearance before the next Carboplatin treatment was 89 (42-155) ml/min. No significant proteinuria or electrolyte disturbances were noted. Carboplatin exhibited antitumor activity in ovarian, endometrial, thyroid and gastric carcinomas. The maximally tolerated dose appears to be 550 mg/m2 every five weeks. A starting dose of 450 mg/m2 seems to be appropriate for Phase II studies. In patients with impaired renal function and/or prior cis-Platin chemotherapy, Carboplatin at doses of 200-500 mg/m2 induced renal and severe hematological toxicity.

Thirty six patients with advanced solid tumors (24 lung: 3 oat-cell, 14 squamous, 7 adenocarcinomas, 3 soft tissue sarcomas, 6 breast carcinomas; 1 seminoma; 2 ovarian adenocarcinomas) entered a phase II study of high-dose ifosfamide (IF) administered in combination with the uroprotective agent sodium 2-mercapto-ethane-sulfonate (Mesna). Fourteen patients had prior treatment; most patients with lung cancer (22/24) were previously untreated; all had measurable disease. The patients median age was 59 (range 31-74). IF was given at 1.8 g/m2 days 1-5 q 4 weeks. Mesna was given after each IF injection at 0, 4 and 8 h randomly, either i.v. (0.36 g/m2) or orally (0.72 g/m2). Twenty-four patients had greater than or equal to 3 courses of therapy, 9 had 2 courses, and 3 had only 1 course; 129 courses were evaluated for toxicity. Mesna was given orally (17 patients, 57 courses) or i.v. (19 patients, 72 courses). The following side-effect were observed: no gross hematuria, microhematuria (14 courses), transitory mild proteinuria (34 courses), leukopenia grade I-II ECOG (26 courses), anemia grade I ECOG (31 courses), 1 case of pancytopenia, alopecia (31 patients), nausea (moderate, 33 courses; severe, 6 courses), vomiting (moderate, 17 courses; severe, 1 course). Five patients showed a partial response (1 oat-cell carcinoma, 2 with squamous lung cancer, 1 with ovarian carcinoma, 1 with breast carcinoma), 14 showed a minor response (2 patients with oat-cell carcinoma, 2 with lung adenocarcinoma, 5 with squamous lung cancer, 1 with seminoma, 1 with sarcoma, 1 with ovarian carcinoma), and 14 showed progression of disease (7 patients with squamous cell lung cancer, 4 with lung adenocarcinoma, 1 with sarcoma, 2 with breast carcinoma). Considering partial plus minor responses, ifosfamide produced some degree of tumor reduction (PR + MR) in 12/23 (52.1%) lung cancer patients. The data reported support the conclusions that Mesna can prevent high-dose IF bladder toxicity, that IF is active in advanced solid tumors, including lung cancer, and that the IF + Mesna combination is a generally safe treatment procedure.

One hundred and twenty-five patients with active rheumatoid arthritis unresponsive to nonsteroidal antiinflammatory drugs were treated at the same center with 156 courses of either hydroxychloroquine (43), gold (29), D-penicillamine (40), or levamisole (44). Life table analysis was used to compare the risks of developing various side effects with treatment termination being the endpoint instead of death. Patients treated with levamisole had the highest risk of developing a complication (67%) and antimalarials the lowest (30%). In terms of long term acceptability, hydroxychloroquine showed fewer complications, gold and D-penicillamine were similar with rash and proteinuria being the main difficulties; however, levamisole caused the most frequent terminations mainly due to rash and leukopenia.

A phase I-II study of KW2083, an analog of mitomycin C (MMC) was performed in a total of 22 patients. KW2083 was escalated by single intravenous administration of 40, 50, 60, 70, and 80 mg/m2 doses. Treatments were repeated every 4-6 weeks unless unacceptable toxicities occurred. The median times taken to reach nadir for each dose level were 9-12 days for leukocytes and 7-13 days for platelets respectively. The median times taken for recovery were 8-22 days for leukopenia and 10-37 days for thrombocytopenia. Variable and non-predictable hematological toxicity was observed in some cases. Biphasic hematological toxicity was observed in 4 courses. Acute toxicity occurred in 17 courses for 11 patients and consisted of nausea (44%), vomiting (13%), diarrhea (2.7%) and stomatitis (2.7%). Nephrotoxicity (elevation of BUN, 8.1% and proteinuria, 5.4%) occurred in 3 patients who had no previous impairment of renal function. Alopecia (8.1%) was also observed. Marked elevations of hepatic enzymes were noted in one patient who developed acute fulminant hepatitis with the second dose of KW2083. Objective response was observed in one of 20 evaluable patients. From this preliminary study, the maximum tolerable dose is 70 mg/m2 and the optimal dose of KW2083 was determined to be 50 mg/m2 at 6-week intervals. KW2083 has been introduced as an MMC analog of potential interest. However, hematological and non of hematological toxicities are very similar to those of MMC and does not appear that KW2083 will supersede MMC.

The Phase I study of N-7-(p-hydroxyphenyl)-mitomycin C (KW 2083, M 83) was performed. The dose-limiting toxicity was leukopenia and thrombocytopenia and a maximum tolerable dose was 70 mg/m2. Nonhematologic toxicities included nausea (44%), vomiting (13%), diarrhea (2.7%), azotemia (8.1%), proteinuria (5.4%), alopecia (8.1%) and elevated hepatic enzymes (2.7%). This Phase I study indicates that the recommended starting dose for Phase II studies for patients without significant myelosuppression would be 50 mg/m2 at 6 week intervals in an intravenous push. KW 2083 should be avoided in patients with impaired renal functions and proteinuria because of permanent renal damages caused by the drug.

Captopril, a competitive antagonist of angiotensin converting enzyme, has been marketed in the United States for the treatment of resistant hypertension. Despite extensive study, its exact mechanism of action remains unclear; decreased renin-angiotensin-aldosterone and sympathoadrenal system activity as well as increased bradykinin and prostaglandin E and F activity have been postulated. The drug decreases peripheral vascular resistance. Controlled trials in resistant hypertension of various etiologies and chronic congestive heart failure have demonstrated sustained effectiveness and therapeutic benefits. Side effects include skin rash, loss of taste, proteinuria, and leukopenia; higher doses and concomitant renal dysfunction appear to be predisposing factors. The benefit-to-risk ratio for captopril clearly justifies its use in resistant cases of hypertension and congestive heart failure, but further experience is needed to evaluate its use in milder forms of these diseases.

The effects on the neonate of severe maternal hypertension originating before the thirty-sixth week of gestation were determined by comparing data obtained on 28 preterm infants born of hypertensive mothers with data from 28 gestational age-matched controls. All hypertensive mothers had diastolic blood pressure greater than or equal to 110 mm Hg, proteinuria, and systemic symptoms of their disease; over half had thrombocytopenia and significant elevations of LDH and SGOT. All hypertensive mothers had been treated intravenously with magnesium sulfate, and 79% received other antihypertensive agents. When compared to control infants, the infants of hypertensive mothers had a significantly higher incidence of somatic growth retardation, microcephaly, thrombocytopenia, leukopenia, neutropenia, low Apgar scores, delayed adaptation, patent ductus arteriosus, hypotonia, and gastrointestinal hypomotility. Apgar scores, platelet count, WBC count, neutrophil count, and weight percentile correlated with the severity of maternal platelet and enzyme abnormalities. The occurrence of gastrointestinal hypomotility, hypotonia, and patent ductus arteriosus may be related to transplacental passage of maternally administered drugs.

Thirty-four cases of SLE treated during the past seven years (1974-1981) in Taipei Municipal Jen-Ai Hospital are reported and analyzed. Diagnosis of SLE was based on ARA preliminary criteria and Hahn's preliminary criteria. There were 32 females (94.2%) and 2 males (5.8%). The mean age at diagnosis was 28.5 years (range 14-51). Clinical manifestations were as follows: facial erythema 24 cases (70.6%), Raynaud's phenomenon 4 cases (11.4%), oral or nasopharyngeal ulceration 7 cases (20.6%), arthritis without deformity 22 cases (64.7%), proteinuria 21 cases (61.8%), pleural or pericardial effusions 13 cases (38.2%), psychosis or convulsions 9 cases (26.5%), hematological abnormalities 25 cases (73.5%). Laboratory findings were as follows: positive ANA test 33/34 (97.0%), hypocomplementemia 10/13 (76.9%), direct Coombs' test 4/18 (22.2%), indirect Coombs' test 1/13 (7.6%), LE cell 19/34 (55.9%), RA Latex 7/17 (41.7%), polyclonal gammopathy 15/17 (88.2%), anemia 25/34 (73.5%), leukopenia 12/34 (35.3%), thrombocytopenia 10/34 (29.4%). Three cases were complicated by herpes zoster, one by hyperthyroidism, and one by autoimmune thyroiditis. Ten cases died, including 4 renal failure, 2 heart failure, 2 cases of committed suicide and 1 case of CNS involvement.

Previous studies provide inconclusive data concerning the nephrotoxicity of myoglobin following muscle injury. We investigated the possibility that released muscle constituents other than myoglobin may be associated with renal damage, and studied accompanying hematological and coagulation changes. An extract of homologous or autologous muscle was infused intravenously in rabbits in a dose of 100 mg of muscle extract protein/kg; equine myoglobin was given to control animals. Experimental animals developed proteinuria, cylindruria, and a 50% reduction in glomerular filtration rate. Leukopenia, thrombocytopenia and evidence of intravascular coagulation also were seen. The muscle extract was shown to have thromboplastic activity; however inhibition of this by phospholipase C did not prevent the changes induced by muscle extract infusion possibly because the intrinsic changes coagulation pathway still was activated. Although moderate hypotension and ECG changes developed in some rabbits, these were not consistent and the renal functional changes appeared to be independent of these factors. Pulmonary and glomerular microthrombi were seen in experimental animals and there was vacuolation of the renal proximal tubular cells. The studies indicate that a number of biological systems are activated following muscle extract infusion and that these may be more important than the nephrotoxicity of myoglobin in the pathogenesis of the renal injury.

Adverse effects to D-penicillamine were studied prospectively over 3 years in 259 patients with rheumatoid arthritis. Ninety-five percent had had gold therapy previously, yet 70% benefited from D-penicillamine therapy. Of the 275 courses given, 160 (58%) were complicated by at least one reaction, including rashes (44%), dysgeusia (20%), gastrointestinal upset (18%), stomatitis (10%), proteinuria (7%), thrombocytopenia (3%), and leukopenia (2%). Their occurrences peaked in the first 6 months of treatment, except for proteinuria and thrombocytopenia, which peaked in the second 6 months. Reactions were commoner at daily doses above 250 mg; mean daily doses for proteinuria, thrombocytopenia, and leukopenia were higher (approximately 600 mg/d) than for the others (approximately 500 mg/d). Of 114 discontinued courses, 73 (27%) were due to adverse reactions. The remaining reactions were controlled by altering dosages and symptomatic treatment. Only obliterative bronchiolitis (two cases) was irreversible; it resulted in the only death in our series, possibly attributable to penicillamine.
