In the community of Kungsbacka, Sweden, with about 48,000 inhabitants, all subjects with colorectal cancer were studied during a three-year period. The incidence was 30 per 100,000 inhabitants per year. In all there were 42 cases. Blood in the stools, anaemia, tiredness, and dizziness were common initial signs and symptoms. Diarrhoea and constipation were also rather frequent. Positive test for faecal occult blood was observed in 40%, negative tests in 12% while in 48% no such test had been performed. The majority of the subjects (64%) first visited a general practitioner (GP). Mean doctor's delay was five months. More than half the cancers were located in the rectal or sigmoid area. Subjects in whom no metastases were observed had a favourable prognosis, compared with those with distant metastases. Since most patients with colorectal cancer first visit a GP for their symptoms, the GP has an important role in the diagnosis of colorectal cancer.

Symptoms by age and sex were studied in two population studies from Gothenburg, Sweden. In general, men and women showed the same age-related pattern. The prevalence of the following symptoms increased with age--sleeping disturbances, pain in the joints, pain in the legs, breathlessness, and impaired hearing. Six symptoms decreased with age--general fatigue, abdominal pain, nausea, diarrhoea, cough, and headache. A group of symptoms showed a curvilinear shape with a peak at the age of 50. In general, women presented more symptoms than men. This was especially true for symptoms of depression and tension. A possible explanation is that women are more attentive to their internal state. A more probable explanation, supported by our study, is that the mental symptoms are related to the woman's situation in life with double work (responsible for both work and family).

Preclinical data suggest synergy of interleukin-2 (IL-2) combined with alpha-interferon (IFN). In addition, toxicities of IL-2 may be decreased by intermittent continuous infusion. The purpose of this trial was to determine the maximum tolerated dose (MTD) of recombinant IL-2 combined with alpha-IFN in patients with renal cancer, colon cancer, melanoma, and malignant B-cell disease. IL-2 was given by continuous i.v. infusion at an initial dose of 5 X 10(5) units (U)/m2/d for 4 days plus IFN at 6 X 10(6) U/m2/d intramuscularly days 1 and 4 weekly for 4 weeks. Patients who achieved a response or stable disease received an additional 4 weeks of therapy. IL-2 doses were increased to 1, 2, 3, 5, and 7 X 10(6) U/m2/d with three to eight patients at each dose level, at each of the two participating institutions. The dose of IFN was 6 X 10(6) U/m2 days 1 and 4 for all but five patients whose IFN dose was doubled to 12 X 10(6) U/m2/d. Forty-three patients were entered on this study with 34 completing at least 4 weeks of therapy. Six patients were taken off study because of Grades III or IV pulmonary, neurologic, or cardiac toxicity; one for progressive disease; one for CNS metastases, and one for personal reasons. All of the toxicities were reversible. Chills and fever were universal, especially on days 1 and 4. Mild and moderate nausea, vomiting, diarrhea, anorexia, malaise, and cutaneous erythema were present in most patients. Fluid retention and occasional pleural effusions were observed at the higher IL-2 doses but were not dose-limiting. Significant hypotension associated with oliguria was seen, and these patients were treated with vasopressors and colloids. None of the patients required ICU admission. Thirty-four patients were evaluable for response. There were 4/18 (22%) renal cell patients who experienced a partial response. No responses were seen in patients with melanoma, lymphoma, or colorectal cancer. The combined debilitating symptoms of fatigue, diarrhea, hypotension, fluid retention, and anorexia defined the MTD as 5 X 10(6) U/m2/d of IL-2 and 6 X 10(6) U/m2 of alpha-IFN.

Recombinant interferon alfa-2a (rIFN alpha-2a) synergistically augments the cytotoxic effects of the antimetabolite fluorouracil (5-FU) against two human colon cancer cell lines. A pilot clinical trial was initiated to determine whether this same combination of agents would show clinical utility greater than that expected with 5-FU alone in patients with advanced colorectal carcinoma. 5-FU was administered at 750 mg/m2/d for 5 days as a continuous intravenous infusion followed by weekly bolus therapy. rIFN alpha-2a was administered at 9 million units subcutaneously three times per week starting on day 1. Doses of 5-FU were modified for mucosal toxicities and myelo-suppression, and doses of rIFN alpha-2a were modified for fatigue and neurologic toxicities. Thirty-two previously untreated patients with advanced colorectal carcinoma were entered into a clinical trial. With the exception of one patient with a destructive lesion of the sacrum, all patients had metastases to visceral organs, abdominal wall, or pelvis. Twenty patients (63%) achieved a partial response, seven remained stable, and five had progressive disease. Mucosal toxicities limited delivery of full projected dose. Two patients died following episodes of watery diarrhea progressing to sepsis. A third died suddenly, secondary to an interstitial pneumonitis. The remainder of the toxicities were managed with dose reductions. At the median follow-up of 8 months, 23 of 32 patients remain alive. Nine are alive at 16 to 30+ months. The early results of this single-institution study are promising, but will require confirmation in a multi-institutional setting currently being conducted by the Eastern Cooperative Oncology Group.

Travelers' diarrhea is only mild or moderate in the majority of cases. Consequently, severe fluid and electrolyte losses are encountered only rarely. Secretory, osmotic, and inflammatory processes in the intestine result in increased losses of fluid and electrolytes due to diarrhea. Disorders of intestinal motor activity, coupled with fluid secretion, may also have a role in causing an increase in the frequency of bowel movements. Several systemic symptoms, such as malaise, fatigue, anorexia, nausea, and fever, are commonly associated with diarrhea and contribute to significant morbidity, which is often sufficient to compromise effective participation in a vacation or business trip. Several putative mechanisms for the systemic symptoms associated with travelers' diarrhea are discussed in light of recent understanding of the enteric nervous system, intestinal neuropeptides and hormones, and other inflammatory mediators released from the bowel wall during enteric infections.

All major types of human interferons (IFNs) have been purified and clinically administered as antitumor agents. We summarize here experience to date with toxicity of IFNs in cancer patients. The acute syndrome consists of fever, chills, myalgias, arthralgias, and headache, with some variation according to type of IFN, route of administration, schedule, and dose. Fatigue, perhaps reflecting CNS toxicity, is the most prevalent nonacute symptom. At high doses, IFNs are neurotoxic; the abnormalities seen by EEG resemble those in diffuse encephalitis. Hematologic toxicity consists mainly of leukopenia, but anemia and thrombocytopenia occur in some patients. Nausea, vomiting, and diarrhea are the main gastrointestinal symptoms. Elevation of serum transaminases seems to reflect liver toxicity. Renal function is well preserved, except for rare instances of acute renal failure. Cardiac toxicity remains questionable, although heart failure and arrhythmias have been associated with the administration of IFNs. Most, if not all, of these effects are reversible or can be ameliorated. With IFN alpha, the type most widely used in clinical studies, doses of 1 million to 9 million units (MU) are generally well tolerated, but doses greater than or equal to 18 MU yield moderate to severe toxicity. Doses greater than or equal to 36 MU can induce severe toxicity and significantly alter the performance status of the patient.

The safety and tolerability of lisinopril were assessed in 1,476 patients [1,165 hypertensives and 311 patients with congestive heart failure (CHF)] and 211 normal volunteers. The duration of lisinopril therapy ranged from 1 day to 16 months, with a mean duration of 105 days. In the hypertensive population, the most frequent clinical adverse experiences on lisinopril alone were headache, dizziness, cough, and diarrhea. Not all of these adverse experiences were thought to be drug related. Five percent of patients were discontinued because of adverse clinical experiences; cough and dizziness were the most common reasons for discontinuation. Two of 1,165 (0.17%) hypertensive patients treated with lisinopril died, compared to 0.41% of hypertensive patients on other therapies. Neither case was considered to be drug related. In patients with CHF, the most frequent clinical adverse experiences were dizziness, diarrhea, hypotension, fatigue, headache, and rash. Not all of these adverse experiences were thought to be drug related. The percent of CHF patients discontinuing because of an adverse clinical experience was 7.4%; the most frequent causes for discontinuation were hypotension, dizziness, or renal impairment. Twelve deaths occurred in 311 CHF patients treated with lisinopril (3.9%) compared to 4/104 (3.8%) of CHF patients treated with placebo and 2/65 (3.1%) treated with captopril. Hypotension, orthostatic effects, or dizziness following the initial lisinopril dose occurred infrequently in patients treated with lisinopril. In hypertensive patients with normal renal function, including those treated previously or concomitantly with diuretic therapy, a first-dose hypotensive episode was reported in six of 955, or 0.6%. The incidence was higher (6.7%) in hypertensive patients with impaired renal function.(ABSTRACT TRUNCATED AT 250 WORDS)

Diesel motors are employed to an increasing extent for occupational transport and fumes from diesel driven vehicles constitute an increasing problem as regards atmospheric pollution but, in particular, they constitute a considerable risk to health for the workers exposed to diesel exhaust fumes in their daily work. In the clinic for occupational medicine, The University Hospital, Copenhagen, 14 garage workers were examined. Eleven of these had been exposed to great quantities of diesel exhaust fumes for 2 to 29 years. All 11 presented acute symptoms due to diesel exhaust fumes in the form of headache, vertigo, fatigue, irritation of mucous membranes, nausea, abdominal discomfort or diarrhoea. Seven persons had been employed for more than five years as garage workers. Six complained of failure of memory, difficulty in concentration, irritability, increased sleep requirement, psychological changes or reduced libido. Neuropsychological examination was undertaken in these six persons and in five of them organic brain damage, mainly of slight extent, was demonstrated. Diesel exhaust fumes contain many toxic substances: carbon monoxide, nitrous gases, sulphur oxides, aldehydes and hydrocarbons. It is not possible to indicate a single compound which is responsible for possible brain damage and a combination effect may well be concerned. This is a casuistic material. Only few investigations have previously been available which illustrated a possible connection between the neurotoxic effects and, in particular, brain damage. It is now considered important to emphasize that this may constitute a problem on exposure to diesel exhaust fumes.(ABSTRACT TRUNCATED AT 250 WORDS)

AIDS-related gastrointestinal disease is common, presenting a challenge to all nutritional support clinicians. Patients frequently suffer from weight loss, diarrhea, malabsorption, and cachexia. Many factors complicate the course of AIDS-related gastrointestinal disease, including decreased food intake (resulting from fatigue and malaise), increased metabolic demand and nutritional requirements, and identifiable gastrointestinal pathology. Gastrointestinal pathology is well-documented, and in approximately 50% of persons with AIDS-related gastrointestinal disease, a causative agent can be identified. In general, treatment of AIDS-related gastrointestinal disease is not always curative. Much of the chronic gastrointestinal dysfunction is caused by recurring opportunistic pathogens that are resistant to chemotherapy. Often, patient care and long-term management can focus only on fluid and electrolyte balance, nutritional support, and symptom control. Even clinically stable patients have been diagnosed as chronically malnourished and, for reasons that remain unclear, are prone to rapid nutritional deterioration during disease exacerbations. Published reports of nutritional assessment and intervention in persons with AIDS are now appearing in the literature. However, the eventual mortality associated with AIDS still results in a hesitancy on the part of many clinicians to prescribe aggressive nutritional support, especially parenteral nutrition. Who to treat and at what stage of illness becomes the question. As new agents, such as AZT, are prescribed on a more frequent basis for persons with AIDS, the use of nutritional support as adjunctive therapy early in the course of disease becomes an issue. Although improving nutrition has not been shown to reverse any of the cellular immunodeficiency caused by HIV infection, quality of life may be improved. In specific cases, nutritional support, whether through diet counseling, food programs, or intervention with enteral or parenteral nutrition, appears to improve strength and endurance, thus enhancing quality of life.

Based on the synergy of sequential methotrexate (MTX) and 5-fluorouracil (5-FU) in vitro and in vivo and the superior antitumor activity of trimetrexate (TMTX) compared with MTX in preclinical models, we carried out a phase I trial of TMTX and 5-FU (fixed dose, 400 mg/m2 per day), both given as 10-min i.v. infusions daily x 5 days, every 28 days. The TMTX dose was escalated from 3.0 to 14.0 mg/m2 per day. In all, 92 evaluable courses were given to 34 patients, half of whom were heavily pretreated with radiation or cytotoxics. Myelosuppression and mucositis were the dose-limiting toxicities but were not different in heavily or minimally pretreated patients; there were five episodes of moderate to severe mucositis. Rash, fatigue, and diarrhea were mild toxicities. Plasma TMTX elimination was biexponential, with a mean t.1/2 alpha of 0.23 h and a t.1/2 beta of 16.7 h. The area under the plasma TMTX concentration versus time curve increased linearly with dose, suggesting first-order elimination. Total plasma TMTX clearance (mean +/- SD) was 14.3 +/- 5.9 ml/min per m2. Renal clearance accounted for approximately 7% of total clearance, indicating biotransformation as the major route of elimination. TMTX was highly protein-bound (97%). Thus, TMTX can be given with 5-FU (400 mg/m2) on a daily x 5-day bolus schedule at the 12 mg/m2 per day dose level, which was the recommended dose of TMTX as a single agent for phase II studies using the 5-day bolus schedule.
