Podophyllum toxicity: case report and literature review.

A case is reported of apparent podophyllum toxicity. The patient was a 17-year-old female Indian who had received some 3 to 8 cc of a 20 percent mixture of podophyllum resin in compound tincture of benzoin (approximately equal to 0.4 gm of podophylotoxin) as an application to her vulvar condylomata. She returned to the hospital 20 hours after application in a comatose state. On examination she demonstrated severe toxicity including bone marrow, liver, and central nervous system. She required a charcoal hemoperfusion at the University of Colorado, and six months after the event has several neurologic and physiologic sequelae. Podophyllum is a potentially severely toxic drug. Great care must be taken when treating patients with this drug. A large mass of condylomata or the status of pregnancy should be relative contraindications to the use of podophyllum.

Retrospective findings of the clinical benefits of podophyllum resin 25% sol on hairy leukoplakia. Clinical results in nine patients.

Hairy leukoplakia was first described as an oral marker of human immunodeficiency virus infection in 1984. The clinical significance of this lesion in an otherwise healthy, high-risk symptom-free person is that it can be an early manifestation of human immunodeficiency virus infection. Because of its benign nature and the lack of clinical evidence that treatment of the lesion improves the prognosis of human immunodeficiency virus-infected patients, systemic therapy with antiviral drugs does not seem warranted at this time. Topical retinoids (Retin-A sol) and systemic antivirals such as acyclovir have been previously tried; however, lesions tend to recur a few days after treatment is discontinued. Nine patients with oral hairy leukoplakia seen at the Oral Medicine Clinic, University of California San Francisco were offered treatment with podophyllum resin 25% sol. All patients had a complete remission of their condition within 1 week (5 patients) or after the second application a week later (4 patients). Side effects were transient and reversible. These remissions of oral hairy leukoplakia lasted from 2 to 28 weeks, which suggests that podophyllum may be a relatively safe and cost-effective treatment of this otherwise symptom-free lesion.

Treatment of HIV-related hairy leukoplakia with podophyllum resin 25% solution.

Ten HIV-infected patients who had bilateral hairy leukoplakia on the tongue were treated with topical podophyllum resin 25% solution. Only one side of the bilateral lesion was treated and the other side served as the control and was not treated. The lesions on both the treatment and control sides were evaluated at day 2, 7, and 30 by an investigator who had not been involved in the initial treatment and had no knowledge of which side had been treated. Therefore the treatment side is compared with the control side in a single-subject design, single-blind control setting. The lesions were judged by the degree of resolution and assigned a number of 0 to 4 with 4 indicating the highest degree of resolution and 0 indicating no resolution or worsening of the condition. The results were analyzed by Student's t test. Significant resolution of hairy leukoplakia was noted on the treatment side compared with the control side at the 2-, 7-, and 30-day levels; the 2-day results were the most significant. Furthermore, the patients reported minimal side effects, which included burning sensation, bad or altered taste, and pain, that were of mild intensity and short duration. The side effects were reported to occur immediately after the topical application. Patient tolerance and acceptance were found to be very favorable. No systemic side effect was reported. We conclude that single topical application of podophyllum resin 25% solution is efficacious in producing significant short-term resolution of HIV-related oral hairy leukoplakia. We also conclude that it is a safe topical regimen with minimal side effects.

Laryngeal papilloma: results of treatment with the CO2 laser and podophyllum.

From 1976 to 1982, 109 patients with recurrent laryngeal papillomas were treated with a total of 548 CO2 laser excisions followed by podophyllum painting. There was high incidence of multiple sites of involvement, especially the tracheobronchial tree (18.3%) and palate (8.3%). Four patients had pulmonary parenchymal involvement. Patients were treated at 2-month intervals until they entered remission. Thereafter, microdirect laryngoscopies were advised at longer intervals. Remission was achieved in 41%; it occurred at all ages although it was most common during adolescence and rarest in the very young and very old. Many patients obtained remission with the CO2 laser after multiple prior cup forceps removals had not achieved remission. Only two tracheotomies (1.8%) were required and no deaths occurred. When compared with mechanical methods of papilloma removal, CO2 laser excision with podophyllum painting represents a clear advance in terms of preservation of laryngeal physiology and avoidance of life-threatening complications.

Podophyllum: suspected teratogenicity from topical application.

A case demonstrating suspected teratogenic effects of topical podophylium is presented. Podophyllum resin was applied five times for a duration of 4 hr from the 23rd to the 29th week of pregnancy. At birth a simian crease on the left hand and a preauricular skin tag were noted. It is suggested that podophyllum be avoided during pregnancy. Alternative treatment for warts of the vaginal, perineal, or anal area are presented.

Podophyllum toxicity: a report of a fatal case and a review of the literature.

A 59-yr-old male ingested 10 g of podophyllum in a fatal suicide attempt. Previously unreported nuclear and cytoplasmic changes were observed in circulating leukocytes. Symptoms did not occur until 10 h after ingestion with loss of reflexes, coma, and a marked lactic acidosis. Despite hemoperfusion, the patient expired 39 h after ingestion. The literature on podophyllum toxicity is reviewed.

Dense bodies and Langerhans granules after application of podophyllum resin.

The application of an alcoholic solution of podophyllum resin at concentrations above 10% for seven hours on guinea-pig udders increases the number of dense intracytoplasmic bodies in the Langerhans cells localized in the epidermis. A close relationship can be established between these inclusions and the typical Langerhans granules in view of the numerous intermediate forms with features of one or the other. Serial sections of these structures confirm the irregularity not only of the lysosome-like bodies but also of the Langerhans granules, which may be fusiform or oblong or even present two vesicular dilatations, one at each end of the rod.

An investigation of the antiviral activity of Podophyllum peltatum.

The antiviral activity of an aqueous extract of Podophyllum peltatum was investigated. The extract was fractionated by reversed-phase chromatography, and podophyllotoxin was found to be the most active component in inhibiting the replication of measles and herpes simplex type I viruses. beta-Peltatin and desoxypodophyllotoxin produced marginal antiviral effects, while alpha-peltatin and picropodophyllotoxin were inactive at the levels tested.

Determination of the aryltetralin lignan content of podophyllum resins and roots/rhizomes.

A simple, quantitatively reproducible method for determining the aryltetralin lignan content of the resins and roots/rhizomes of Podophyllum hexandrum and P. peltatum is described. The method confirms that P. hexandrum resins and roots/rhizomes contain approximately four times the quantity of lignans as do those of P. peltatum and also that there is a significant variation in the lignan content of P. hexandrum resins.

Guinea pig maximization test: Podophyllum lignans.

The guinea pig maximization test was used to study the sensitizing potential of Podophyllum lignans; 0.5% of each drug in propylene glycol was used for induction and 0.01%, 0.05%, 0.1% and 0.5% preparations for topical challenge. The 0.1% and 0.5% preparations caused non-allergic toxic reactions associated with the cutaneous destructive influence of these drugs; allergic responses did not occur.

Intralesional interferon alfa-2b treatment of condylomata acuminata previously resistant to podophyllum resin application.

The safety and efficacy of intralesionally administered interferon alfa-2b were assessed in 11 patients suffering from condylomata acuminata for four to 10 months for whom application of podophyllum resin had proved unsuccessful. Three warts from each patient were injected with 10(6) IU interferon alfa-2b three times a week for three weeks. Treatment was followed by a 13 week observation period. Interferon alfa-2b treatment resulted in a highly significant (p less than 0.0001) reduction in the mean size of the treated warts, which decreased from an initial size of 29 mm2 to 2-3 mm2 by week 16. In six out of the 10 patients completing the trial, both the test condylomata and adjacent control warts cleared completely; a recurrence was observed in one of these six patients. Influenza like symptoms (headache and myalgia) were the most common side effects reported, though they were mild in nature and not disabling. These results corroborate those of previous trials with interferon preparations and indicate that its antiviral activity makes it a possible treatment for this sexually transmitted disorder.

[Bacterial leaf blight affecting Syngonium podophyllum in Argentina].

Bacterial leaf blight of Syngonium podophyllum caused by Xanthomonas campestris pv. syngonii is recorded for the first time in Argentina. The first symptom of the disease was an interveinal watersoaking of leaves, the tissues became chlorotic and finally necrotic over areas of about 4 cm. The identification of the causal microorganism was based on disease symptoms, morphological, physiological and biochemical characteristics and pathogenicity test.
