42 episodes of verified or clinically suspected cytomegalovirus (CMV) infection in 40 bone marrow transplant (BMT) recipients were treated with foscarnet (trisodium phosphonophormate hexahydrate). CMV infection was verified in 31/42 treatment episodes. Symptoms treated were pneumonia (n = 17), pancytopenia with or without fever (n = 12), enteritis (n = 5), fever (n = 4), encephalitis (n = 2), retinitis (n = 1) and hepatitis (n = 1). Foscarnet was given as a continuous intravenous infusion. Side-effects observed were increase in serum creatinine (38%), decrease in serum calcium (19%), increase in serum bilirubin (12%), decrease in hemoglobin concentration (7%), increase in serum calcium (5%), increase in serum transaminase (5%), hypophosphatemia (2%) and tremor (2%). CMV was eradicated from blood and/or urine in 11/25 (44%) of assessable treatment episodes with infection verified by isolation. Overall clinical improvements including eradication of CMV, afebrility and/or improvements in laboratory abnormalities were seen in 14/31 (45%) episodes of verified infection. All 15 patients with CMV interstitial pneumonia (CMV IP) died. We conclude that foscarnet is nephrotoxic but otherwise well tolerated with moderate clinical and virostatic effects on CMV infection. The effect on CMV IP is discouraging.

Patients with haematological malignancies with HLA-identical marrow donors were randomized to treatment with cyclosporin (CSA) or methotrexate (MTX). Two of the 29 patients randomized to MTX died before engraftment compared with none of the 30 treated with CSA. Engraftment by leucocytes (P less than 0.0001), granulocytes (P less than 0.02), and reticulocytes (P less than 0.01) was faster among the CSA patients. There were no significant differences between the two groups regarding transfusions, hospitalization and incidence of early septicaemia. Granulocyte transfusions were required in seven of 29 MTX and two of 30 CSA patients (not significant: NS). Overall (grade I-IV) acute graft-versus-host disease (GVHD) was more common (P = 0.001) in the CSA patients. Grade II-IV acute GVHD was seen in 40% of the CSA patients compared with 22% in the MTX patients (NS). In the adult patients grade II-IV GVHD was slightly more common (P less than 0.05) in those treated with CSA compared with MTX. Chronic GVHD appeared in 30 and 39% in the two groups respectively. Actuarial 3-year survival was 58% for the CSA patients and 69% for the MTX patients. There were no significant differences regarding the incidence of interstitial pneumonitis or relapses between the two groups. The side-effects of CSA treatment includes nephrotoxicity (83%), hepatotoxicity (20%), hirsutism (43%), hypertension (23%), tremor (27%) and gingival hyperplasia (27%). Serum creatinine values were increased at 3 and 6 months in the CSA group but were within the normal range after 6 months. A blind study on oral side-effects revealed that CSA patients more often had a normal mucosa (P = 0.025) and less frequently had mucositis (P = 0.01) compared with the MTX group.

Theophylline toxicity has been recognized since its introduction into clinical medicine. Clarithromycin is a new oral macrolide antibiotic with excellent antibacterial activity and rare adverse effect. Patients with upper respiratory infection are often treated with theophylline and clarithromycin concurrently. We report a case of acute renal failure due to acute rhabdomyolysis caused by the interaction of theophylline and clarithromycin. A 72-year-old man visited our hospital because of coughing and a sore throat continuing for 1 week. He was diagnosed as having the common cold with a bronchial asthmatic symptom and was prescribed 200 mg/day of sustained-release theophylline for the treatment of asthma for 7 days. One week later, he visited our hospital again. Radiographic study of the chest revealed mild interstitial pneumonia and 200 mg/day of sustained-release theophylline and 400 mg/day of clarithromycin were administrated concomitantly. Five days after the second visit, the patient was admitted to our hospital because of generalized twitching, muscular weakness, high fever and serious general condition. He experienced generalized muscular twitching and tremor. Blood urea nitrogen was 106.1 mg/dl, serum creatinine was 7.4 mg/dl, serum creatinine kinase (CK) was 36,000 IU/l (normal 15-130 IU/l), CK isozyme revealed the following ratio: BB 0%, MB 1% and MM 99%. He was diagnosed as having acute renal failure with rhabdomyolysis caused by the interaction of theophylline and clarithromycin. Hemodialysis therapy was started. After 5 weeks, his serum creatinine was markedly decreased. It is well-known that clarithromycin enhances the serum concentration of theophylline by inhibition of the cytochrome P450-dependent pathway in hepatocytes. Theophylline toxicity may be enhanced when clarithromycin is administrated concomitantly, especially to elderly patients with dehydration.

We report a 60-year-old man with a 6-year history of tremor in his hands. He noted the onset of short of breath and gait disturbance in 1994; both of these symptoms were slowly progressive. Then recently he developed fever two months prior to the present admission. He was admitted to the rheumatology department of our hospital and neurological consultation was asked on December 13, 2000. On neurologic examination, he showed Gottron sign and fine crackle in both lungs. Pertinent neurological findings were bilateral dysmetria in finger-to-nose and heel-to-knee tests and a broad-based gait. In addition, he showed intention tremor in upper extremities more on the left. Romberg sign was positive. Deep tendon reflexes were decreased. Vibratory sensation was reduced at the wrists. The patient's hemoglobin was 11.1 g/dl, with a mean corpuscular volume of 92.0 fl. Vitamin B12 level was 190 (reference range, >230 pg/ml). Serum lactic acid, pyruvic acid and ceruloplasmin were slightly elevated. Chest X-ray showed interstitial pneumonia. Muscle biopsy showed grouping of small angular fiber. Brain MRI showed diffuse atrophy of the cerebral cortex and the cerebellum hemisphere. Thalamotomy did not improve his tremor. He was admitted again in November 2001. General worsening of his neurological findings was observed. IL2-receptor was markedly elevated. Serum anti-Hu, Yo and Ri antibodies were negative. An anaplastic carcinoma was found in his jejunum. He died from respiratory failure in February 2002. He was discussed in a neurological CPC and the chief discussant arrived at a conclusion that the patient had paraneoplastic syndrome. Other diagnosis entertained included MERRF, GSS, Ramsay Hunt syndrome, subacute combined degeneration, spinocerebellar degeneration. Majority of the participants thought that paraneoplastic syndrome was most likely. Post-mortem examination revealed poorly differentiated carcinoma in the small intestine. Myeline pallor was noted in the posterior and the lateral columns in the thoracic spine. Neuronal cell loss was observed in the Purkinje cell and granular cell layer in the cerebellum. Sural nerve demonstrated loss of myelinated fibers and grouping of small fibers. Neuropathological findings were consistent with Friedreich ataxia; nevertheless, no mutation was reported in frataxin in Japan. The neuropathologist concluded that neuropathological diagnosis was a spinocerebellar ataxia with neuropathological similarities to Friedreich ataxia.

The aim of this observational prospective study was to assess the incidence rate and the characteristics of adverse drug reactions (ADRs) induced by amiodarone during the long-term follow-up of 98 French patients. Inclusions were performed between March 1994 and April 1997. Eligible patients were consecutive outpatients for whom amiodarone was initiated for the first time. The treatment had to be taken for at least 6 months if no ADR required its withdrawal. A cohort of 57 men and 41 women, mean age 72.6 years (SD: 8.6), was followed for a mean period of 38 months. The incidence rate of ADRs during the overall follow-up period was 13.91 cases for 100 person-years. Recorded ADRs were 13 hypothyroidism (incidence rate for 100 person-years: 4.61 [95% confidence interval: 4.58-4.63], 5 hyperthyroidism (1.62 [1.60-1.63]), 10 bradycardia and/or conduction ADRs (3.48 [3.46-3.50]), 7 photosensitivity (2.27 [2.25-2.28]), 1 storage disease (0.33 [0.32-0.33]), 3 interstitial pneumonitis (0.97 [0.96-0.98]), 2 peripheral neuropathies (0.65 [0.64-0.66]), 1 tremor (0.32 [0.32-0.33]) and 1 gastrointestinal disturbances (0.32 [0.32-0.33])). Thyroid and cardiac ADRs occurred mainly during the first 6 months. According to the French system of pharmacovigilance, 27 ADRs were "probable/likely" and 14 were "possible." Hypothyroidism, cardiac ADRs, and photosensitivity were the most frequent ADRs. None of the ADRs had a fatal outcome in this study.

Because of its excellent optical performance and electrical properties, TiO2 has a wide range of applications in many fields. It is often considered to be physiologically inert to humans. However, some recent studies have reported that nano-sized TiO2 may generate potential harm to the environment and humans. In this paper the in vivo acute toxicity of nano-sized TiO2 particles to adult mice was investigated. Mice were injected with different dosages of nano-sized TiO2 (0, 324, 648, 972, 1296, 1944 or 2592 mg kg(-1)). The effects of particles on serum biochemical levels were evaluated at various time points (24 h, 48 h, 7 days and 14 days). Tissues (spleen, heart, lung, kidney and liver) were collected for titanium content analysis and histopathological examination. Treated mice showed signs of acute toxicity such as passive behavior, loss of appetite, tremor and lethargy. Slightly elevated levels of the enzymes alanine aminotransferase and aspartate aminotransferase were found from the biochemical tests of serum whereas blood urea nitrogen was not significantly affected (P < 0.05). The accumulation of TiO2 was highest in spleen (P < 0.05). TiO2 was also deposited in liver, kidney and lung. Histopathological examinations showed that some TiO2 particles had entered the spleen and caused the lesion of spleen. Thrombosis was found in the pulmonary vascular system, which could be induced by the blocking of blood vessels with TiO2 particles. Moreover, hepatocellular necrosis and apoptosis, hepatic fibrosis, renal glomerulus swelling and interstitial pneumonia associated with alveolar septal thickening were also observed in high-dose groups.
