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.

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.

Podophyllum derivatives (CPH 82) compared with placebo in the treatment of rheumatoid arthritis.

The efficacy, tolerance, and safety of CPH 82 (semisynthetic lignan glycosides) (Conpharm AB) for patients with rheumatoid arthritis (RA) were assessed in a 12-week double-blind placebo-controlled study. Thirteen patients out of 15 in the CPH 82 group and 10 out of 15 in the placebo group completed the study. No improvement was seen in placebo treated patients. Patients treated with CPH 82 showed a statistically significant improvement in most clinical and immunological variables. Some patients treated with CPH 82 reported gastrointestinal discomfort (diarrhoea and abdominal pain).
