Impetiginous Cutaneous Leishmaniasis after COVID-19 Infection in a Patient with Poor Cardiac Profile: A Case Report and Literature Review

Cutaneous leishmaniasis incidence has been rising in the past couple of decades. Standard therapy often includes antileishmanial drugs; however, due to their low safety and toxicity threshold, alternative treatments are being investigated. The association between COVID-19 and cutaneous leishmaniasis remains unclear and exploring this connection may offer crucial insights into the pathophysiology of and treatment strategies for infected patients. In this article, we describe a case of a male patient with a history of cardiac and other comorbidities who presented with cutaneous leishmaniasis in the form of impetigo-like skin lesions after being infected with COVID-19. Due to the patient's poor cardiac profile, sodium stibogluconate was not used and an alternative therapeutic approach was employed. The patient was treated with oral terbinafine, cryotherapy on specific lesions, and a course of cephalexin. Following the course of treatment and subsequent follow-up, the patient exhibited complete resolution and healing of the lesions with scarring, and no active lesions or recurrence were observed. This case highlights the potential for alternative treatment strategies for cutaneous leishmaniasis in patients with comorbidities and emphasizes the importance of further research to better understand the link between COVID-19 and cutaneous leishmaniasis.

Topical terbinafine in the treatment of cutaneous leishmaniasis: triple blind randomized clinical trial

Leishmaniasis is a spectrum of disease condition with considerable health impacts, caused by different species of Leishmania. This disease is currently endemic in 98 countries and territories in the world. There are many treatment modalities for cutaneous leishmaniasis. The use of topical terbinafine in the treatment of cutaneous leishmaniasis has recently been considered. Eighty-eight participants more than two years old with proven acute CL by a positive direct smear were randomly allocated to one of the two study arms: first group received meglumine antimoniate (Glucantime) 20 mg/kg/day intramuscular injection (IM) plus a placebo ointment (Mahan Vaseline) for 20 days. The second group received meglumine antimoniate (Glucantime) 20 mg/kg/day IM plus topical terbinafine, for 20 days and were monitored closely by dermatologist during the course of the study. Crude regression analysis showed that there was no significant difference between placebo and intervention group regarding partial or complete treatment (partial treatment: HRcrude = 1.1, CI 95 % = 0.7-1.7; complete treatment: HRcrude = 1.1, CI 95 % = 0.8-1.7). Although, there was no statistically significant different between the two treatment groups, but clinically it seems that the treatment rate in those who receive glucantime plus terbinafine was more effective than the other group. However this rate depended on the type of lesions. As data indicated ulcerated nodules, papules and plaque in experimental group have been completely improved two times faster than placebo group. Ulcerated nodules, nodules and plaque were partially improved faster in those used tebinafine than placebo ointment.

Syndrome de Stevens-Johnson et aggravation d’un lupus systémique induits par la terbinafine

BACKGROUND

There have been published reports of induction and aggravation of subacute systemic lupus erythematosus of lupus by terbinafine. We report the case of female patient with systemic lupus erythematosus who, after treatment with terbinafine, presented a Stevens Johnson syndrome eruption, together with renal exacerbation of her connective tissue disease.

OBSERVATION

A 25 - year-old woman was followed for 4 years for systemic lupus erythematosus was no renal involvement. The patient was stable under corticosteroids (20 mg/d) and chloroquine (200 mg/d). She was treated with terbinafine onychomycosis caused by Trichophyton rubrum. Seven days after trunk and limbs, with cheilitis affecting the mucous membrane and bilateral conjunctivitis. This rash was followed by epidermolysis involving 10% of the cutaneous area. Stevens-Johnson syndrome was diagnosed. Laboratory tests indicated massive hematuria and proteinuria, and the renal needle biopsy sample showed signs of class III lupus glomerulonephritis. The anti-histone antibodies were highly positive. The patient was treated with systemic corticosteroids (1 mg/kg/d), chloroquine was recommenced and cyclophosphamides were given in a bolus. The outcome of the patient's eruption and lupus was favorable.

DISCUSSION

Although induction and worsening of lupus by terbinafine have already been reported, the present case differs through the concomitant occurrence of eruption on treatment with terbinafine and severe relapse of lupus, thus suggesting the involvement of a shared immunological mechanism.

Pigmentierung des Gesichtes unter Therapie mit Terbinafin

A 65-year-old patient presented with grey-brownish maculae localized on the face. He had been treated with oral terbinafine due to onychomycosis, and the first spots manifested after 4 weeks of therapy. Other drugs were not taken by the patient, who was otherwise in a healthy condition. Histology showed melanin localized within macrophages in the upper and lower dermis. Cutaneous side effects are well described in patients treated with terbinafine and usually present as urticaria or eczema. Severe reactions may occur in rare cases. Hyperpigmentation has not yet been described as a consequence of oral terbinafine. Grey hyperpigmentation as it occurred in our patient has been described as a side effect of therapy with minocycline, amiodarone, tricyclic antidepressants, or heavy metals. This case report shows that drug-induced hyperpigmentation should also be considered if the patient takes drugs not known for this kind of side effect.

Erythema multiforme ID reaction in atypical dermatophytosis: a case report

BACKGROUND

Erythema multiforme (EM) is an uncommon mucocutaneous disorder, characterized by widespread erythematous-oedematous targetoid lesions, considered as a reaction pattern to many different stimuli.

OBSERVATION

Presentation is made of a classical EM eruption concomitant to an inflammatory, atypical dermatophytosis of the ala nasi, observed in a 37-year-old male at the Dermatology Department of Cagliari, Italy.

METHODS

Laboratory investigations revealed normal complete blood count and biochemistry profile. A direct microscopic examination with 20% potassium hydroxide of the nasal skin scales and of the vibrissae indicated the presence of dermatophyte hyphae and spores invading the rhinothrix. Culture confirmed a Trycophyton mentagrophytes infection. Specific determination of antiviral immunity in the blood (TORCH) was negative for recent infections, while the cell-mediated response, investigated with a delayed skin multitest, showed a marked positivity for the tricophyton antigen. Systemic therapy with terbinafine (250 mg/day) led to complete clinical and mycological recovery of the atypical ringworm in 30 days. Multiforme lesions rapidly improved and completely disappeared in 7 days.

CONCLUSIONS

ID reaction to a distant focus of dermatophyte infection very rarely presents as EM. The presented case fits all the essential criteria required for the diagnosis of an ID reaction. The atypical clinical presentation of the ringworm infection, with marked involvement of the intranasal hairs, seems to have induced an inflammatory allergic response, similar to that evoked by sycosis.

Itraconazole versus terbinafine in the management of onychomycosis: an overview

Ever since the introduction of itraconazole and terbinafine in the management of onychomycosis, there has been a revival of interest in the latter. In order to comprehend the intricate emerging scenario, an endeavor has been made to form a distinct outline in the shape of an overview on several of their facets. The review, therefore, envisages forming and facilitating instant decision-making.

Association between terbinafine and arthralgia, fever and urticaria: symptoms or syndrome?

PURPOSE

The antifungal agent terbinafine has been approved for marketing in The Netherlands since 1992. Adverse drug reactions (ADRs) may occur in about 10% of the patients, the majority gastrointestinal disorders and skin reactions. Since the introduction of terbinafine, the Netherlands Pharmacovigilance Foundation Lareb received eight reports of arthralgia during the use of this drug. In four reports the additional presence of skin reactions was mentioned, two of these reports concerned urticaria. Two patients who reported arthralgia also had a fever. These reports were described in more detail, and analysed statistically in order to determine whether symptoms are interrelated.

METHODS

All reports with known gender and a reporting date between 1 March 1992 and 1 January 1999, concerning patients older than 10 years, were included. The extent to which the symptoms urticaria, fever and arthralgia were interrelated was examined by logistic regression modelling.

RESULTS

Case series as well as the results of the statistical analysis show a clustering of symptoms among reports of patients using terbinafine. Both urticaria and arthralgia were statistically significantly associated with reports on terbinafine compared to all other reports in the database.

CONCLUSION

The findings might point towards a clustering of these symptoms in patients using terbinafine. Possibly these symptoms have a shared aetiology, presumably an immunological reaction.

Cutaneous adverse effects associated with terbinafine therapy: 10 case reports and a review of the literature

Terbinafine is an allylamine antifungal agent widely used to treat dermatophyte onychomycosis and dermatomycoses. We report 10 severe cutaneous adverse reactions associated with terbinafine therapy which required discontinuation of the antifungal agent: erythema multiforme (five patients), erythroderma (one), severe urticaria (one), pityriasis rosea (one) and worsening of pre-existing psoriasis (two patients). The spectrum of cutaneous adverse effects associated with terbinafine therapy is reviewed. Patients should be counselled about discontinuing terbinafine at the onset of a cutaneous eruption and about seeking medical advice about further management.

Terbinafine: an update

Oral terbinafine was first introduced in the United Kingdom in February 1991 and was approved for the treatment of onychomycosis in the United States in May 1996. It is estimated that 4 million patients worldwide have been treated with oral terbinafine as of December 1996. The efficacy of terbinafine in the treatment of onychomycosis and other dermatomycoses is reviewed. The adverse-effects profile of oral terbinafine is evaluated.

Terbinafine therapy may be associated with the development of psoriasis de novo or its exacerbation: four case reports and a review of drug-induced psoriasis

Adverse effects may occur in 10.4% of patients receiving terbinafine therapy, with cutaneous reactions in 2.7%. We describe the development of psoriasis in four patients who took oral terbinafine. Two patients had plaque-type psoriasis that flared 12 and 17 days, respectively, after starting terbinafine. Another patient developed pustular-type psoriasis de novo after 27 days of terbinafine therapy. The fourth patient was a psoriatic with stable plaque disease who experienced a pustular flare after taking terbinafine for 21 days. We are aware of only one report in the literature in which a patient developed pustular psoriasis de novo after 5 days of terbinafine therapy. In all patients the psoriasis cleared or lessened after discontinuation of terbinafine and institution of antipsoriatic therapy.

Oral terbinafine in tinea capitis in children

Tinea capitis is a disease that frequently affects children. In most cases systemic antimycotic treatment is necessary Griseofulvin is still the drug of choice, but requires prolonged periods of treatment (several months). To estimate the efficiency and tolerability of terbinafine for treatment of tinea capitis in children, four patients (aged 3-9 years) with tinea capitis proven by culture were treated with terbinafine at a dose of 125 mg a day for different periods (4-10 weeks). Isolates were subjected to minimal inhibitory concentration testing against terbinafine and griseofulvin. In all four cases terbinafine treatment resulted in complete remission. The clinical response was accompanied by negative culture results on follow-up. Terbinafine was well tolerated in each case. Determination of the minimal inhibitory concentration confirmed the excellent in vitro activity of terbinafine against dermatophytes. Controlled studies involving a larger number of children are necessary to answer questions concerning dose and duration of terbinafine treatment as well as the frequency and severity of drug-related side-effects.
