Preliminary clinical results indicate that the cytostatic agent mitoxantrone is an effective and very tolerable substance for treating multiple sclerosis (ms). Our own experience, added to the findings of other pilot studies, seems to indicate that disease progression can be slowed in a majority of patients with rapidly progressive ms. Mitoxantrone is mainly excreted by the hepato-biliary pathways and therefore it can be used in patients with renal insufficiency or chronic cystopyelitis, a frequently occurring condition in ms. The side effects observed in our therapeutic scheme which could be attributed to mitoxantrone were tolerable. Mild gastrointestinal complaints were occasionally reported and vomiting was very rare. A carcinogenic effect from mitoxantrone has not been reported. A decrease in the leucocyte count is to be expected 6-15 days following treatment administration. Potential cardiotoxicity represents the primary long term adverse reaction and thus patients with cardiovascular risk factors should not be treated with mitoxantrone. Once a cumulative dosage of 140 mg/m2 is reached cardiac function tests, including echocardiography with measurement of the left ventricular ejection fraction, should be routinely carried out preceding each treatment administration in all patients. Mitoxantrone is currently not licensed for use in patients with ms and therefore should be restricted to patients with rapid disease progression where other generally accepted treatment modalities have failed.

Hypermagnesemia is a well-known cause of hypotension and cardiac dysfunction but not well recognized is the induction of paralytic ileus. This report details the second and third adult patients reported with hypermagnesemia-induced paralytic ileus. The first patient was a 65-year-old white woman with normal renal function, who had consumed large amounts of magnesium citrate and milk of magnesia. As magnesium blood level fell from 5.1 mg/dl on admission to 2.4 mg/dl on day 3, the vomiting, obstipation, and abdominal distension resolved. The second patient was a 67-year-old woman with mild renal insufficiency, who consumed a large amount of Epsom salts containing magnesium sulfate to treat her constipation. Magnesium levels of 8.1 mg/dl on admission fell to below 3.1 mg/dl on the third hospital day and the paralytic ileus resolved. Mechanical obstruction was ruled out by colonoscopy, gastrographin enema, and barium small bowel series in both patients. Although the clinical findings of muscle weakness, flaccid paralysis, respiratory muscle paralysis or cardiac arrest due to hypermagnesemia are well described in the literature, intestinal smooth muscle dysfunction leading to paralytic ileus has only been reported in one other adult patient. The laboratory and clinical course of these two patients strongly suggest a causal relationship between hypermagnesemia and paralytic ileus.

We evaluated 27 adult patients with chronic hypokalaemia (K+ = 2.9 +/- 0.2 mmol/l), documented over at least 5 years, in whom the cause of the hypokalaemia had not been clarified in spite of previous testing. In 15 patients it was possible to establish a diagnosis by a thorough outpatient workup (diuretic abuse (n = 5), surreptitious vomiting (n = 8), laxative abuse (n = 1), renal tubular acidosis (n = 1)). Commonly utilized tests such as measurements of plasma renin activity, plasma aldosterone, and urinary potassium concentration proved not to be useful in the differential diagnosis of these patients. In contrast the following were diagnostically important: in surreptitious vomiting the hypochloraemia, the mild renal insufficiency, and the extremely low urinary chloride concentration; in diuretic abuse the high urinary concentration of chloride together with repeatedly positive toxicology screens for diuretics; in laxative abuse the high stool weight and extremely low urinary sodium concentration. In the remaining 12 patients none of these diagnoses applied and further tests for suspected Bartter's syndrome were done in the hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Milk-alkali syndrome is characterized by progressive hypercalcemia, systemic alkalosis, and renal insufficiency. After calcium carbonate is ingested with diary products, hypercalcemia and alkalosis may develop in susceptible persons, particularly those with underlying renal insufficiency. We describe a young woman who neither drank milk nor had peptic ulcer disease, yet who ingested enough calcium carbonate to require admission to an intensive care unit for acute renal failure. Chronically bulimic, she was taking Rolaids (Warner-Lambert Co, Morris Plains, NJ), which contained calcium carbonate, and was eating yogurt daily to prevent osteoporosis. We discuss the characteristics and complex metabolic interactions of the milk-alkali syndrome, a critical but generally reversible electrolyte disorder. Early recognition of coincident hypercalcemia and alkalosis and prompt cessation of calcium carbonate ingestion are essential for successful recovery. Finally, we suggest that nephrologists should discourage patients with renal insufficiency and chronic vomiting from consuming calcium-containing antacids and excessive dietary calcium.

A total of 29 patients with stage IV colorectal cancer were entered into a phase II trial of bolus interleukin-2 (IL-2) and interferon-alpha (IFN alpha) (3 x 10(6) U/m2 of each cytokine given i.v. q8h x 15 doses and repeated in 2 weeks). Immunologic parameters measured on isolated peripheral blood lymphocytes revealed increased activated T cells with upregulated natural killer and lymphokine-activated killer activity. Among 24 evaluable patients, there were 4 partial responses (17%) of short duration ( < or = 6 months). Three of the responding patients had been refractory to prior chemotherapy. Overall median survival in the 24 evaluable patients was 18.5 months. Therapy necessitated an inpatient setting, with the most common toxicities being hypotension, hepatic insufficiency, fever, hypocalcemia, nausea/vomiting, and renal insufficiency. There were two treatment-related deaths. Because neither IL-2 nor IFN alpha alone has significant activity against colorectal cancer, the responses observed in this study suggest a potential synergistic effect between the two cytokines. However, the toxicity and short duration of response without survival benefit do not support the routine use of this regimen as a therapeutic modality for this tumor histology.

Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often ineffective. Gastritis, duodenitis and peptic ulcer are often found in adults with CRF on regular haemodialysis and following renal transplantation. Despite persistent hypergastrinaemia, gastric acid secretion is decreased rather than increased in most of these patients, and active peptic disease appears to be promoted by the removal of the acid output inhibition (neutralisation of gastric acid by ammonia) that follows active treatment. Helicobacter pylori, on the other hand, does not seem to play a significant role in the pathogenesis of peptic disease in CRF. Gastro-oesophageal reflux has been found in about 70% of infants and children with CRF suffering from vomiting and feeding problems, and thus appears to be a major problem in these patients. In a number of symptomatic patients with CRF, gastric dysrhythmias and delayed gastric emptying have also been found; hence there appears to be a complex disorder of gastrointestinal motility in CRF. Serum levels of several polypeptide hormones involved in the modulation of gastrointestinal motility [e.g. gastrin, cholecystokinin (CCK), neurotensin] and the regulation of hunger and satiety (e.g. glucagon, CCK) are significantly raised as a consequence of renal insufficiency, and can be reverted to normal by renal transplantation. Furthermore, several other humoral abnormalities (e.g. hypercalcaemia, hypokalaemia, acidosis, etc.) are not uncommon in CRF. By directly affecting the smooth muscle of the gut or stimulating particular areas within the central nervous system, all these humoral alterations may well play a major role in the gastrointestinal dysmotility, anorexia, nausea and vomiting in patients with CRF. Specific pharmacological and nutritional interventions should thus be considered for the treatment of vomiting and feeding problems in CRF.

The authors report a case of post-traumatic rhabdomyolysis in a victim of a car accident who, after having being initially examined at an emergency ward, was sent home having been requested to return for a control visit a few days later. The patient did not attend the control visit on the appointed day but returned to the same emergency ward eight days after the accident suffering from vomiting, general malaise and violent pain in the left forearm that appeared swollen. Anamnesis revealed a severe condition of rhabdomyolysis with dehydration, pale red urine and general signs of marked renal insufficiency. Tests showed marked myoglobinemia and myoglobinuria, very high CPK, azotemia, creatinemia, transaminase and high diastasemia. Given the disappearance of peripheral pulse and the severe neurovascular impairment of the left forearm caused by edematous compression, it was decided to proceed to surgical decompression using extensive longitudinal fasciotomy under supraclavicular anesthesia. After surgery peripheral pulse returned to normal, as was confirmed by Doppler. After adequate hydration while renal insufficiency lasted, hemodialysis was commenced immediately and repeated during the following days. Given that all the tests had improved and results were virtually within the norm, the patient was transferred to the medical ward after eight days for continuation of therapy. It is important to underline the importance of possible signs, such as oleguria, dark urine, swelling and edemas of the limbs, in injured patients. If renal insufficiency occurs, it is important to commence early hemodialysis. On day 23 the patient was again transferred to the intensive care ward because he presented epigastric pain and vomiting. CAT showed acute pancreatitis which resolved leading to full recovery after 20 days.

A dysentery outbreak in the Central African Republic village of Zemio was diagnosed as "Shigella flexneri" by the Pasteur Institute in Bangui (IPB) in February 1996; 2 months later there was an outbreak of hemorrhagic colitis. 108 patients presented with bloody diarrhea; cramping abdominal pain, fever, nausea, and vomiting were uncommon. The illness lasted between 5 days and 3 weeks (average, 8 days). Antibiotics were ineffective. Four patients died and several developed hemolytic-uremic syndrome. Stool cultures done at IPB tested negative. PCR was used to detect enterohemorrhagic Shiga-like toxin (SLT) 1 and 2, the invasivity gene ipaH, and the attaching and effacing gene eaeA. DNA fragments of 130 and 494 nucleotides corresponding to amplified SLT1 and eaeA were found in 80% of the specimens tested. No amplification was obtained for SLT2 or for ipaH in specimens collected during the second epidemic. These results suggest the presence of enterohemorrhagic Escherichia coli and the absence of Shigella. The number of reported cases of acute bloody diarrhea in infants and adults in Bangui has increased since 1996. E. coli O157:H7 was isolated from two fatal adult cases. Smoked zebu meat was suspected in several hospital cases (bloody diarrhea, hemolytic anemia, and renal insufficiency) in which non-fermenting sorbitol E. coli O157:H7 was not isolated. In two cases of acute diarrhea, other serotypes of E. coli were indicated by retrospective PCR on stools which were positive for SLT1 and for eaeA and negative for invasivity. A study was conducted in Bangui on 290 cases (33 with bloody diarrhea) and 140 controls. Patients were not paired because of civil unrest in the city. The questionnaire included demographic and socioeconomic characteristics, environmental factors, and habitual food consumption. The major contributing factor was consumption of locally made meat pies (kanda), which were made with smoked zebu meat. Kanda is stored at ambient temperature, often for days, before it is sold in markets or along roads. Before 1996, E. coli was not reported as a cause of bloody diarrhea in the Central African Republic.

This report describes a 12-year-old girl who developed vaccine-type pneumococcal septicemia (type 4, Danish nomenclature) 2 years after splenectomy for recurrent idiopathic thrombocytopenia despite vaccination with the 23-valent vaccine 4 weeks before surgery and antibiotic prophylaxis with penicillin V. The disease presented as high fever with shivering and vomiting followed by disseminated petechiae and a deteriorated general condition. Initial laboratory studies showed severe sepsis with leucocytopenia and thrombocytopenia, a markedly elevated CRP, and disseminated intravascular coagulation. Despite antibiotic treatment, which was initiated with clindamycin, cefotaxime and trimethoprim/sulfamethoxazole and was switched to cefotaxime and penicillin after the result of the blood culture had been obtained, the patient had to be ventilated, and hemofiltration became necessary because of acute renal insufficiency. Furthermore, she required amputation of all her toes because of severe necrosis. No type-specific pneumococcal antibody titers were detected during and after infection. It remains unclear whether the susceptibility to Streptococcus pneumoniae was due to primary failure of antibody production or a decline in antibody levels after vaccination. Patients and/or their relatives should be informed that neither vaccination nor continuous antibiotic prophylaxis can guarantee full protection against infection with S. pneumoniae in patients after splenectomy.

Previous data suggested interaction of cisplatin with interferon (IFN) in non-small cell lung cancer and a possible effect of IFN in maintaining remission in small cell lung cancer (SCLC). This study was designed to further examine the effect of IFN in the treatment of extensive disease (ED) SCLC. Forty previously untreated patients with performance status (PS) of 0-2 (Zubrod scale) were treated with etoposide (100 mg/m2 for 3 days), cisplatin (25 mg/m2 for 3 days) (EP), and recombinant IFN-alpha2a (rIFN-alpha2a) (5 x 10(6) U/m2 for 3 days) for six cycles (induction), followed by rIFN-alpha2a (5 x 10(6) U/m2) thrice weekly and megestrol acetate (40 mg q.i.d.) as maintenance therapy for 6 months or until progressive disease or intolerable toxicity was documented. Patients were 25 men (62%) and 15 women (38%), median age 58 (28-76), median Zubrod performance status 1 (0-2). Major sites of metastasis include liver (55%), bone (42%), bone marrow (25%), and adrenal gland (18%). Of 40 eligible patients accrued to this trial, 35 were evaluable for response, and 37 were evaluable for toxicity. There were 3 complete and 28 partial responses, for an overall response rate of 89%. With 39 of 40 patients followed until death, median survival (Kaplan-Meier) is estimated at 46 weeks (95% CI range 35-55). Twenty patients completed six cycles of induction, and 16 received maintenance therapy, median 2 cycles (range 1-3). Major toxicity during induction included grade 4 granulocytopenia in 24%, grade 2-3 nausea or vomiting or both in 41%, grade 2 fatigue in 24%, grade 2 anorexia in 22%, and grade 2-3 renal insufficiency in 9% of 175 total courses of chemotherapy administered. Toxicity during the maintenance phase was notable for grade 2-3 fatigue in 43%, grade 2-3 anorexia in 24%, grade 2-3 weight loss in 10%, and grade 3-4 anemia in 17% of 30 courses. There were no treatment-related deaths. The addition of rIFN-alpha2a to EP in induction chemotherapy of ED SCLC, followed by rIFN-alpha2a and megestrol acetate maintenance therapy, was reasonably well tolerated. The complete and overall response rates and duration of remission and survival appear to be similar to those generally obtained with EP alone in similar patients.
