Vidarabine therapy for severe herpesvirus infections. An unusual syndrome of chronic varicella and transient immunologic deficiency.

Six patients with severe herpesvirus infections were successfully treated with vidarabine. One patient had a previously undescribed syndrome of chronic cutaneous varicella infection of eight months' duration, associated with transient but complete duppression of lymphocyte response to conconavalin A. Other diagnoses were severe varicella pneumonia, progressive cytomegalovirus pneumonia associated with acute lymphocytic leukemia, herpes simplex encephalitis, severe zoster associated with stage IV lymphoma, and disseminated herpes simplex in a patient receiving high doses of steroids. All patients showed cessation of new lesions or abrupt clinical improvement between days 2 and 4 after initiation of therapy, and all were cured of their clinical infection. Dramatic improvement in all of our patients and the minimal toxicity observed make vidarabine suitable for use in severe herpesvirus infections.

Severe Mycoplasma pneumoniae pneumonia.

Four cases of severe Mycoplasma pneumoniae infection are reported which were treated in a single hospital over the course of 4 years. The difficulties in the diagnosis of M. pneumoniae infections are eminently demonstrated by these cases. Because of the fact that it generally takes 2-o weeks to make this diagnosis, the physician must utilize clues of limited reliability. If gram stains and culture of sputum fail to demonstrate any bacterial pathogen and the patient has a chest X-ray compatible with this diagnosis as well as a white blood count less than 15,000/mm3, M. pneumoniae infection may be present. A good antimicrobial choice in such a situation is erythromycin.

Role of infection in chronic bronchitis.

Twenty-five patients with chronic bronchitis were studied intensively from 1968 to 1972. Viral, bacteriologic, mycologic, and mycoplasmal studies, both serologic and cultural, were carried out in an attempt to determine the role these agents play in exacerbations. All of the usual viral agents associated with exacerbations and 2 members of the coronavirus group, 229E and OC43, were detected. One third (33.6 per cent) of the 116 exacerbations observed could be related to viral infection or Mycoplasma pneumoniae (1 exacerbation). Viral infection was also noted to occur during periods of remission but was more commonly associated with periods of exacerbation(P less than 0.001). No interrelationship between viral and bacterial infection was apparent and neither Streptococcus pneumoniae nor Haemophilus influenzae was present more frequently in the sputum of patients in exacerbation. However, the number of S. pneumoniae organisms present in the sputum was significantly greater (P=0.04) during exacerbation than during remission and their presence was significatnly correlated with increases sputum purulence (P LESS THAN 0.01). This was not true of H. influenzae. Ampicillin was effective in clearing the sputum of S. pneumoniae but not of H. influenzae; the reverse was true of tetracycline.

Distressing side-effects of minocycline hydrochloride.

Minocycline hydrochloride is a tetracycline derivative that has been advocated as the drug of choice in the treatment of meningococcal carriers. Recently, we studied a group of 30 patients who experienced a large number of side-effects after receiving minocycline for treatment of meningococcal meningitis. Twenty-seven of 30 (90%) suffered from dizziness, vertigo, ataxia, weakness, nausea, and vomiting. These symptoms appeared within the first 72 hours of taking minocycline, and disappeared within 48 hours of stopping the medication.

Contraception and cervical colonization with mycoplasmas and infection with cytomegalovirus.

The relationship of cervical colonization of genital mycoplasmas and infection with cytomegalovirus (CMV) was studied in 66 intrauterine device (IUD) users as contrasted to 60 patients using oral contraception and 50 patients using neither an IUD nor oral contraception. No significant increase in colonization or genital mycoplasmas or infection with CMV was noted in IUD users. No CMV was isolated from users of the cooper-t IUD. It is unlikely that genital mycoplasmas are related to either the increased immunoglobulin levels seen in patients using the IUD or the antifertility effects of the IUD.

Increased susceptibility of Neisseria gonorrhoea from a rural area.

The in vitro susceptibility of 18 to 24 isolates of Neisseria gonorrhoea were tested against 12 different antimicrobial agents. These isolates represent all of the gonococcal organisms which had been isolated by the bacteriology laboratory of the Vermont State Department of Health from 1 March to 31 July 1972 and originated from patients cultured in Vermont. These isolates were considerably more susceptible to penicillin G and tetracycline than are current isolates from elsewhere in the United States and Canada. Possible explanations for this difference are discussed.
