OBJECTIVE: This report describes a case of mitomycin-induced pulmonary toxicity and reviews the incidence of this adverse effect, reported patterns of toxicity and associated dosages of the drug, and the use of corticosteroids in the management of pulmonary toxicity. DATA SOURCES: Information about our patient was obtained in part from the medical chart; we had also treated him personally in the past. We conducted a MEDLINE search of the English language literature (restricted to human studies) from 1966 to 1991 and manually searched Index Medicus for current information. STUDY SELECTION: All case reports that described pulmonary toxicity possibly associated with mitomycin were reviewed. DATA EXTRACTION: Studies were evaluated for the dosages of mitomycin given to patients, the nature and onset of symptoms, management course, and corticosteroid use. DATA SYNTHESIS: Our case is similar to others described in the literature. The incidence of mitomycin-induced pulmonary toxicity has been reported to range from 2 to 38 percent. Concurrent vinca alkaloid administration may potentiate the risk of an acute pulmonary insult secondary to mitomycin use. The toxicity is usually of slow onset and the average total dosage of drug implicated is 78 mg. A formal evaluation of corticosteroid treatment has not been performed, but various authors have reported success with different regimens. CONCLUSIONS: The incidence of pulmonary toxicity associated with mitomycin is unpredictable, but more likely to occur at higher dosages. Treatment with corticosteroids is encouraged to improve pulmonary response.

Objective To describe a case of isoniazid-associated psychosis and review the incidence of this adverse effect. Data Sources Information about the patient was obtained from the medical chart. A MEDLINE search of the English-language literature published from 1950 to 1992 was conducted and Index Medicus was manually searched for current information. Study Selection All case reports describing isoniazid-associated psychosis were reviewed. Data Extraction Studies were evaluated for the use of isoniazid, symptoms of psychosis, onset of symptoms, and dosage of isoniazid. Data Synthesis The case report is compared with others reported in the literature. The incidence of isoniazid-associated psychosis is rare. Conclusions The mechanism of isoniazid-associated psychosis is uncertain. It appears that isoniazid was associated with the psychosis evident in our patient and in the cases reviewed.

Objective: To review the literature discussing the use of dexrazoxane (e.g., Zinecard, ICRF-187) to prevent doxorubicin-induced cardiotoxicity. Data Sources: Pertinent English-language reports of studies in humans were retrieved from a MEDLINE search (January 1980-January 1997); search terms included chelating agents, razoxane, dexrazoxane, Zinecard, ICRF-187, ADR-529, and ICRF-159. Study Selection: Representative articles discussing the chemistry, pharmacology, pharmacokinetics, dosing, and administration of dexrazoxane and those discussing clinical trials were selected. Data Extraction: Data were extracted and analyzed if the information was relevant and consistent. Studies were selected for review in the text on the basis of study design and clinical end points. Data Synthesis: Dexrazoxane is a chemoprotective agent developed to prevent cardiac tissue toxicity. Dexrazoxane exerts a cardioprotective effect with some clinically significant toxicities; it may also interfere with the antitumor activity of doxorubicin. Until there are sufficient data to support its use in first-line supportive care therapy, dexrazoxane should be reserved for use in patients responding to doxorubicin-based chemotherapy but who have risk factors for cardiac toxicity or have received a cumulative doxorubicin bolus dose of 300 mg/m2. Conclusions: The management of doxorubicin-induced cardiotoxicity has led to the development of supportive care drugs that specifically counteract the dose-limiting toxicities. Dexrazoxane may not completely eliminate the concern about doxorubicin-induced cardiotoxicity, but it may open new avenues for continuing doxorubicin-based chemotherapy.

Tolerance Study

Objective: To review rifabutin-associated uveitis and discuss the mechanism and potential role of drug interactions with clarithromycin and fluconazole in contributing to this adverse event. Data Sources: A MEDLINE search (1991 through September 1994) of English-language literature using the main MeSH headings “rifabutin” and “uveitis” and the subheadings “adverse effects” and “chemically induced.” Relevant articles also were selected from references of identified articles. Abstracts from recent medical conferences of infectious diseases, pharmacology, and HIV were screened for additional data. Study Selection and Data Extraction: All articles and abstracts reporting uveitis potentially related to rifabutin were considered for inclusion. Fifty-four cases were identified. Pertinent information from the case reports, as judged by the authors, was selected and synthesized for discussion. Data Synthesis: Rifabutin is being prescribed increasingly for the treatment and prophylaxis of Mycobacterium avium complex (MAC) infection in the HIV-infected population. Uveitis was initially thought to be a rare, dose-limited complication of rifabutin therapy. In an early dose-ranging tolerance study, uveitis was associated with daily doses of 1200 mg or more. Because this toxicity appeared to be dose-related, lower dosages (300–600 mg/d) of rifabutin were selected for study in subsequent clinical trials. More recent reports noting the association of uveitis with these lower dosages of rifabutin have raised concerns about the prevalence of this adverse event. In the 54 identified cases, patients presented with symptoms of unilateral or bilateral uveitis from 2 weeks to more than 7 months following initiation of rifabutin therapy. In all reported cases, patients were receiving concurrent therapy with clarithromycin and/or fluconazole, both of which have inhibitory effects on rifabutin metabolism. In most cases, uveitis resolved within 1–2 months following discontinuation of rifabutin with or without administration of topical corticosteroids. Conclusions: Rifabutin is prescribed frequently for the prophylaxis and treatment of MAC infection, especially in patients with HIV. Uveitis is a rare, dose-related toxicity of this therapy. The risk of rifabutin-associated uveitis may be increased in patients receiving concurrent therapy with clarithromycin or fluconazole because of drug interactions. Patients receiving therapy with combinations of any of these agents should be warned about signs and symptoms of uveitis and be monitored closely for the development of rifabutin toxicity. If uveitis develops, rifabutin therapy should be discontinued promptly.

New Treatment

OBJECTIVE: To review the pharmacology, pharmacokinetics, clinical efficacy, adverse effects, drug interactions and precautions, and dosing recommendations of rifaximin, a new nonabsorbed antimicrobial agent for travelers' diarrhea. DATA SOURCES: A MEDLINE search (1966–July 2004) was conducted to extract human and animal research data in the English language on rifaximin. STUDY SELECTION AND DATA EXTRACTION: Randomized, double-blind, placebo-controlled trials were reviewed and included to evaluate the efficacy of rifaximin in the treatment of travelers' diarrhea. DATA SYNTHESIS: Rifaximin is approved for the treatment of travelers' diarrhea in patients ≥12 years of age with diarrhea caused by noninvasive strains of Escherichia coli. Rifaximin was superior to placebo and trimethoprim/sulfamethoxazole and equivalent to ciprofloxacin in the primary clinical endpoint of the time to the last unformed stool passed. CONCLUSIONS: Rifaximin is a viable alternative to ciprofloxacin for the treatment of travelers' diarrhea. As rifaximin is not systemically absorbed, it offers the advantage of leading to the development of less resistance compared with systemically absorbed antibiotics, in addition to fewer systemic adverse effects and drug interactions. However, the potential for cross-resistance between rifaximin and rifampin, as well as with other classes of antibiotics, is of concern and needs to be elucidated.

OBJECTIVE: To review information on desloratadine, a nonsedating antihistamine. DATA SOURCES: An English-language MEDLINE search was conducted (1966–July 2002). References of identified articles were subsequently reviewed for additional data. Schering Corporation provided unpublished information. STUDY SELECTION/DATA EXTRACTION: Articles and abstracts pertaining to desloratadine were considered for inclusion, with emphasis on randomized, placebo-controlled, double-blind trials. DATA SYNTHESIS: Desloratadine is approved for the treatment of symptoms associated with seasonal allergic rhinitis (SAR), perennial allergic rhinitis (PAR), and chronic idiopathic urticaria (CIU) in patients aged ≥12 years. In placebo-controlled trials, desloratadine demonstrated superior efficacy as a once-daily treatment of SAR, PAR, and CIU. Data suggest that desloratadine has antiinflammatory and decongestant activity. CONCLUSIONS: Desloratadine appears to be a “me-too” agent, with no major differences compared with other second-generation antihistamines.

The Relationship

Objective: To evaluate whether there is a relationship between antimicrobial therapy and the development of thrombocytosis. Data Sources: Literature was accessed through EMBASE (1977-June 2012) and MEDLINE (1977-June 2012) using the terms thrombocytosis and antimicrobial. In addition, reference citations from publications identified were reviewed. Study Selection and Data Extraction: All English-language publications identified were evaluated. For case reports, the Naranjo probability scale was used to calculate the likelihood of the drug causing the reaction. Data Synthesis: Thrombocytosis occurring during antimicrobial therapy is well documented, with several case reports and clinical trial observations. However, a direct causal relationship is not yet supported by the available literature. Platelets are welt known to be an acute phase reactant, with an elevated count occurring after acute conditions such as blood loss, inflammation, or infection. Thrombocytosis during antimicrobial therapy may be the result of an infectious process and not an adverse drug event. Conclusions: Based on the current available literature, a definitive link cannot be established between antimicrobial therapy and occurrence of thrombocytosis.

OBJECTIVE: TO summarize the pharmacology, pharmacokinetics, efficacy, and safety of acetazolamide and to evaluate its therapeutic role in patients with epilepsy. DATA SOURCES: A computerized search of the MEDLINE (OVID) database (1966–1994) was used to identify publications regarding acetazolamide. The MEDLINE search was supplemented by information from textbooks. STUDY SELECTION: Included were English-language review articles, clinical trials, cohort studies, and case reports. Topics investigated included basic pharmacology, therapeutics, toxicology, adverse reactions, dosage, administration, and pharmacokinetics of acetazolamide. DATA SYNTHESIS: Acetazolamide, a carbonic anhydrase inhibitor, has been approved for the treatment of epilepsy since 1953. Acetazolamide is primarily used in combination therapy with other antiepileptic medications in both children and adults although it may be used as monotherapy. Drug concentration monitoring has not been found to be routinely beneficial. Adverse effects include kidney stones, metabolic acidosis, lethargy, appetite suppression, paresthesias, and rare blood dyscrasias. Partial tolerance may develop to the antiepileptic activity. CONCLUSIONS: Acetazolamide is a beneficial adjunctive agent in the pharmacotherapy of epilepsy and should be considered in refractory epilepsy. Although it may be useful in partial, myoclonic, absence, and primary generalized tonic—clonic seizures uncontrolled by other marketed agents, acetazolamide has been inadequately studied by current standards and its use has been limited.

OBJECTIVE: TO review the literature that compares Zolpidem with triazolam, with an emphasis on efficacy and safety in humans. DATA SOURCES: Information was retrieved from a MEDLINE search (1983–1996) of the English-language literature using the terms triazolam and zolpidem. STUDY SELECTION: Reports of clinical trials comparing the safety and efficacy of zolpidem and triazolam were included in this review. DATA EXTRACTION: Data were evaluated according to study design, efficacy, and adverse effects. Pertinent information was selected and the data synthesized into a review format. DATA SYNTHESIS: Zolpidem and triazolam have similar pharmacokinetic and pharmacodynamic effects in humans. Clinical trials have shown that usually recommended, equipotent dosages of zolpidem and triazolam do not differ with respect to pharmacokinetics, efficacy, tolerability, residual effects, memory impairment, rebound insomnia, abuse potential, or other adverse effects. CONCLUSIONS: Zolpidem offers no distinct therapeutic advantage over triazolam for the treatment of insomnia.

OBJECTIVE: TO review the symptoms, pathophysiology, and treatment of the serotonin syndrome (SS). DATA SOURCES: A MEDLINE search (1957–1995) of the English-language literature pertaining to the SS was performed. Additional literature was obtained from reference lists of pertinent articles identified through the search. STUDY SELECTION AND DATA EXTRACTION: All articles were considered for possible inclusion in the review. Pertinent information, as judged by the authors, was selected for discussion. DATA SYNTHESIS: The SS, an occasionally fatal disorder, is characterized by symptoms such as mental status changes, seizures, myoclonus, and blood dyscrasias. Both the central and peripheral serotonergic systems and several serotonin receptor types are involved in the symptomatology of the SS. The pathogenesis of SS may be due to endogenous as well as iatrogenic deficits in peripheral serotonin metabolism, a stimulus for release of serotonin, and interactions with other neurotransmitter systems. Lorazepam, serotonin-blockers, and nitroglycerin have been used successfully to treat SS. CONCLUSIONS: The SS is increasingly recognized and reported in the literature. Clinical and basic science research have increased our understanding of the pathophysiology, conditions, and agents that may predispose to the development of the syndrome. Newer treatment strategies are discussed.
