Since their introduction in clinical practice in 1980, ACE inhibitors have been found useful in the treatment of hypertension and CHF. In hypertension, they are effective as monotherapy in 40% to 50% of the patients, and in combination with diuretics or calcium antagonists, they are effective in up to 85% of the patients. They are well tolerated, are not associated with depression, impotence, bronchospasm or metabolic derangements such as hypokalemia, hyperuricemia or hyperglycemia, and do not have adverse effects on the quality of life. As a result, they are preferred in hypertensive patients with CHF, left ventricular dysfunction, mental depression, older age, coronary artery disease, metabolic disorders, chronic destructive pulmonary disease, and peripheral vascular disease. In CHF they cause long-lasting hemodynamic and symptomatic improvement, improve exercise tolerance, and may lower mortality in certain patient subsets. Evolving new indications for ACE inhibitors include the diagnosis of renovascular hypertension, the prediction of surgical success, the treatment of scleroderma renal crisis, the reduction of proteinuria, renal protection, cardioprotection, the improvement of arterial compliance, in Bartter's syndrome and idiopathic edema, etc. ACE inhibitors are usually well tolerated but in some instances they may cause class-specific side effects such as hypotension; usually reversible azotemia or renal failure, especially in patients with renal artery stenosis or with CHF with low blood pressure; cough; angioedema; and hyperkalemia. Differences among ACE inhibitors are emerging and include chemical class (e.g., zinc ligand), biotransformation, potency, pharmacokinetics, prodrugs, tissue effects, additional pharmacologic properties, and drug interactions.

Between January 1992 and December 1998 we collected clinical, epidemiological and treatment data on all patients diagnosed of tuberculosis in our specialized unit. Five hundred sixty-seven patients (70% male and 30% female) were studied prospectively. The rate of new cases increased until 1995 and decreased during the last three years of study. Mean patient age was 38.8 years, with nearly 64% of patients under 45 years of age. Predisposing disease, mainly chronic alcoholism, was present in 36%. Fifteen percent belonged to a high-risk social group (6.5% were drug addicts and 6.3% lived inside secure institutions). The mean time elapsing from the appearance of symptoms until referral to our service was 80.4 days and the most common clinical picture at presentation was general unwellness with cough and expectoration (46%) followed by hemoptysis (18%). Cavitation was visible in 48.5% of x-rays, while alveolar infiltrates were seen in 33%, pleural effusion in 12% and lymph node involvement in 10%. Adult tuberculosis was diagnosed in 80% of cases, 10% were reactivations and 9% were primary. Bacteriological diagnosis was available for 85%. Therapy usually involved six months with hydrazide, rifampicin and pyrazinamide (81%). Therapy was generally well-tolerated, although analyses revealed some anomalies, such as transaminase alteration (18%) and hyperuricemia (19%). Therapy was changed because of toxicity in only 2.6%. Follow-up after therapy was strict and the rate of successful cure was 97.5%. We conclude that diagnosis was not prompt enough and believe that knowledge of epidemiological, clinical and evolutionary data, as well as monitoring of real rates of cure of treated patients justifies the existence of specialized centers for managing tuberculosis.

All currently available antihypertensive drugs can cause adverse drug reactions. Potential adverse drug reactions should already be taken into account when a new antihypertensive regimen is started. It is furthermore important to ask at follow-up visits specifically about common adverse reactions. The aims of this article are therefore to shortly summarise common and typical adverse drug reactions of antihypertensives. All antihypertensives may cause dizziness, hypotension, allergies, rashes, gastrointestinal complaints and dry mouth. Thiazide diuretics furthermore may cause electrolyte disturbances, dehydration and hyperuricemia, betablockers may cause bronchospasm, bradycardia, cold extremities and sleep disturbances and calcium antagonists may cause flushing, ankle oedema and gingival hyperplasia. Concerning potential lethal adverse drug reactions, it is important to know that ACE inhibitors and angiotensin receptor antagonists are contraindicated in all patients with a history of angioedema. However, angiotensin receptor antagonists are well-suited alternatives for patients with ACE inhibitor-induced cough or hypogeusia. Rare adverse drug reactions are commonly recognised only after drug approval based on spontaneous reporting. This demonstrates the importance of considering medications as potential causes of new complaints and symptoms and to reports such suspected adverse drug reactions to the national pharmacovigilance centres. Only the local or international accumulation of comparable spontaneous reports allows the drug regulation agencies to recognise new and unexpected adverse drug reactions early and to initiate appropriate measures.

BACKGROUND Tumor lysis syndrome is common in hematological malignancy, but less frequent in chronic and solid tumors. Almost always it is observed after chemotherapy or radiotherapy initiation, but rarely occurs spontaneously. CASE REPORT A 89-year-old female with stable chronic lymphocytic leukemia was admitted to the hospital because of worsening dyspnea and dry cough. Her vital signs were normal, except for sinus tachycardia. On physical examination, she appeared distressed, dyspneic, sweaty but afebrile, anxious, but alert and well oriented. Lung examination revealed reduced air entry with bibasilar crackles. No peripheral edema was seen, pulses were normal, and no signs of deep vein thrombosis were observed. Laboratory analysis revealed leukocytosis; but normal hematological and biochemical parameters. Intravenous (IV) furosemide and antibiotics (IV ceftriaxone and orally azithromycin) were started along with steroid therapy (methylprednisolone 62.5 mg, IV). The treatment with steroids lasted for 1 day only, and in the following day, the patient was switched to prednisone (20 mg/day orally) for only 1 additional day. White blood cell count increased on day 1, 2 and 3 after admission, along development of hyperuricemia, hyperphosphatemia, hyperkalemia, acute renal failure and elevated troponin levels. Hemodiafiltration/hemodialysis was initiated, and the patient was discharged after serum concentrations of these electrolytes and kidney function were restored. One month after discharge, the patient denied any malaise and was at stable condition. CONCLUSIONS Herein, we present a case of a patient with stable chronic lymphocytic leukemia, who developed spontaneous tumor lysis syndrome after short low dose of steroid therapy. This case highlights the importance of including spontaneous tumor lysis syndrome in the differential diagnosis of any acute renal failure in the constellation of any malignancy.
