Electrocardiographic changes and myocarditis in trichinellosis: a retrospective study of 154 patients.

The frequencies of electrocardiographic (ECG) abnormalities and myocarditis were determined, retrospectively, among 154 cases of trichinellosis [101 males and 53 females, with a mean (S.D.) age of 35.60 (14.64) years] who were hospitalized at the University Hospital for Infectious Diseases in Zagreb, Croatia, over a 5-year period. Eighty-seven (56%) of the patients, most of them in the invasive phase of infection with Trichinella spiralis, were found to have abnormalities when examined by 12-lead, resting electrocardiography. The ECG disorder most frequently observed was a non-specific ventricular repolarization disturbance (with ST-T wave changes), followed by bundle-branch conduction disturbances, and sinus tachycardia. The other ECG disorders recorded, during various phases of the infection, were sinus bradycardia, right bundle-branch block, supraventricular and ventricular extrasystoles, low-voltage QRS complexes in standard limb leads, first-degree atrio-ventricular block, and atrial fibrillation. Eighteen (12%) of the patients were identified as cases of myocarditis (13 in the invasive phase and five in the convalescent) and two (1.3%) as cases of myopericarditis. One patient developed acute myocardial infarction 28 days after the onset of disease and died soon thereafter; an autopsy revealed multiple necroses and fibroses of the myocardium and thrombus of a coronary artery. Although ECG abnormalities appear to be a common feature of trichinellosis, especially during the invasive phase of the disease, they are rarely associated with a poor prognosis. A transient, non-specific, ventricular-repolarization disturbance is the abnormality most commonly observed.

Duration of clinical symptoms in female patients with acute urethral syndrome caused by Chlamydia trachomatis treated with azithromycin or doxycycline.

One hundred fifty-one female patients with acute urethral syndrome caused by Chlamydia trachomatis were examined. First, patients were divided into two groups, those with clinical symptoms present < 3 weeks before the start of treatment, and those with clinical symptoms > or = 3 weeks prior to the beginning of therapy. Then patients were further divided into groups and randomized to receive azithromycin once daily in a single dose of 1.0 g or 500 mg once daily for 6 days, or to receive doxycycline 100 mg b.i.d. for 14 days or 100 mg b.i.d. for 7 days (8 study groups in all). Clinical and bacteriological efficacy was evaluated 3 weeks after the end of therapy. In the group of patients with disease symptoms lasting for 3 weeks or longer, the eradication and clinical cure rates were significantly higher after administration of azithromycin in a dose of 1x500 mg/6 days than after a single dose of 1.0 g (p<0.01), and after administration of doxycycline 2x100 mg/14 days than by using doxycycline 2x100 mg/7 days (p<0.05).

[Clinical and epidemiologic characteristics of hemorrhagic fever with renal syndrome].

Clinical and epidemiological data on 16 patients with HFRS admitted to the University Hospital of Infectious Diseases in Zagreb during the past 10 years (1977-1986) are reported. In 13 of them, the diagnosis was confirmed serologically by indirect fluorescent method. All but two were men between 20 and 45 years of age (80% of patients). The disease appeared sporadically only. According to the domicile, way of living and working all the patients but three mentioned the contact with rodents in the fields or in other places (mill, storehouse). Three patients live in Zagreb and there was no possibility to get infected out of the town. The disease had moderate course, more rarely severe course when shock and acute renal failure developed. General symptoms with fever and algias dominated (febrile stage). Some of the patients had ophthalmic disturbances. Patients with a pronounced gastroenteritis developed shock the most frequently. In some of the patients back and abdominal pains followed by obstipation appeared. HFRS was incriminated disease because of febrile stage followed by the acute renal failure, oliguria, azotemia, polyuria and low urine osmolity. One female patient with active rheumatoid arthritis died after two-week staying in hospital due to irreversible shock followed by cardiopulmonary and renal failure.

[Comparative study of thiabendazole and mebendazole in strongyloidiasis].

Taking into consideration some statements about better efficacy and good tolerability of mebendazole and since thiabendazole has not been produced in our country the past few years we have conducted a study evaluating mebendazole, in comparison with thiabendazole in the treatment of patients with strongyloidiasis. Strongyloidiasis is a disease that should be treated with an effective and active drug since it can rapidly progress and be fatal in patients with disturbed immunocompetence. One hundred and ten patients with strongyloidiasis were treated with oral thiabendazole in a dosage of 50 mg/kg daily for two days; the other group of 41 patients was given mebendazole in a dosage of 10 mg/kg/day orally for five days. Clinical evaluations, parasitologic and hematologic tests were performed within three months after the therapy. Patients were considered to have been cured if parasitologic findings were negative and abnormal blood eosinophilia decreased below 0.09 (733/microliters). According to these criteria thiabendazole was effective in 96.4% of patients and mebendazole in 44% of patients only. We conclude that thiabendazole has still to be regarded the drug of choice in treating patients with strongyloidiasis. Mebendazole is far less effective in patients with this helminthiasis and very probably only suppresses the infection. The reports of other studies on the effect of some of the newer benzimidazole antihelmintics as cambendazole, albendazole and flubendazole have shown that they are toxic or less effective in the treatment of strongyloidiasis.
