zithromax and Leishmaniasis--Cutaneous

On the American continent, cutaneous and mucocutaneous leishmaniasis (CL and MCL) are diseases associated with infection by several species of Leishmania parasites. Pentavalent antimonials remain the first-choice treatment. There are alternative interventions, but reviewing their effectiveness and safety is important as availability is limited. This is an update of a Cochrane Review first published in 2009.. To assess the effects of interventions for all immuno-competent people who have American cutaneous and mucocutaneous leishmaniasis (ACML).. We updated our database searches of the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, LILACS and CINAHL to August 2019. We searched five trials registers.. Randomised controlled trials (RCTs) assessing either single or combination treatments for ACML in immuno-competent people, diagnosed by clinical presentation and Leishmania infection confirmed by smear, culture, histology, or polymerase chain reaction on a biopsy specimen. The comparators were either no treatment, placebo only, or another active compound.. We used standard methodological procedures expected by Cochrane. Our key outcomes were the percentage of participants 'cured' at least three months after the end of treatment, adverse effects, and recurrence. We used GRADE to assess evidence certainty for each outcome.. We included 75 studies (37 were new), totalling 6533 randomised participants with ATL. The studies were mainly conducted in Central and South America at regional hospitals, local healthcare clinics, and research centres. More male participants were included (mean age: roughly 28.9 years (SD: 7.0)). The most common confirmed species were L. braziliensis, L. panamensis, and L. mexicana. The most assessed interventions and comparators were non-antimonial systemics (particularly oral miltefosine) and antimonials (particularly meglumine antimoniate (MA), which was also a common intervention), respectively. Three studies included moderate-to-severe cases of mucosal leishmaniasis but none included cases with diffuse cutaneous or disseminated CL, considered the severe cutaneous form. Lesions were mainly ulcerative and located in the extremities and limbs. The follow-up (FU) period ranged from 28 days to 7 years. All studies had high or unclear risk of bias in at least one domain (especially performance bias). None of the studies reported the degree of functional or aesthetic impairment, scarring, or quality of life. Compared to placebo, at one-year FU, intramuscular (IM) MA given for 20 days to treat L. braziliensis and L. panamensis infections in ACML may increase the likelihood of complete cure (risk ratio (RR) 4.23, 95% confidence interval (CI) 0.84 to 21.38; 2 RCTs, 157 participants; moderate-certainty evidence), but may also make little to no difference, since the 95% CI includes the possibility of both increased and reduced healing (cure rates), and IMMA probably increases severe adverse effects such as myalgias and arthralgias (RR 1.51, 95% CI 1.17 to 1.96; 1 RCT, 134 participants; moderate-certainty evidence). IMMA may make little to no difference to the recurrence risk, but the 95% CI includes the possibility of both increased and reduced risk (RR 1.79, 95% CI 0.17 to 19.26; 1 RCT, 127 participants; low-certainty evidence). Compared to placebo, at six-month FU, oral miltefosine given for 28 days to treat L. mexicana, L. panamensis and L. braziliensis infections in American cutaneous leishmaniasis (ACL) probably improves the likelihood of complete cure (RR 2.25, 95% CI 1.42 to 3.38), and probably increases nausea rates (RR 3.96, 95% CI 1.49 to 10.48) and vomiting (RR 6.92, 95% CI 2.68 to 17.86) (moderate-certainty evidence). Oral miltefosine may make little to no difference to the recurrence risk (RR 2.97, 95% CI 0.37 to 23.89; low-certainty evidence), bu. Evidence certainty was mostly moderate or low, due to methodological shortcomings, which precluded conclusive results. Overall, both IMMA and oral miltefosine probably result in an increase in cure rates, and nausea and vomiting are probably more common with miltefosine than with IMMA. Future trials should investigate interventions for mucosal leishmaniasis and evaluate recurrence rates of cutaneous leishmaniasis and its progression to mucosal disease.

Cutaneous leishmaniasis (CL) treatment is based on pentavalant antimony (sbv) drugs which are accompanied by many side effects and are facing ever-increasing resistance. Topical treatment of CL is an attractive alternative avoiding toxicities of parenteral therapy while being administered through a simple painless route. The liposomal formulations of different drugs have recently been increasingly used in the treatment of several types of leishmaniasis. The efficacy of a topical liposomal azithromycin formulation was compared with intralesional meglumine antimoniate (glucantime) in the treatment of CL. Sixty-six patients with 97 lesions who met our inclusion criteria were randomly divided into two groups. One group was administered with the topical liposomal form of azithromycin twice daily. The other group was treated by weekly intralesional injections of glucantime with a volume of 0.5-2 cm3 into each lesion till complete blanching of the lesion occurred. Clinical evaluations were performed weekly during the treatment course (8 weeks) by a single dermatologist for both groups. Per-protocol analysis showed no statistically significant difference between the two groups (p = 0.84, 95% confidence interval (CI) = 0.764 (0.714-0.821). Serious drug side effects were not observed in either group. Topical liposomal azithromycin has the same efficacy as intralesional glucantime in the treatment of CL.

Old World cutaneous leishmaniasis (OWCL) is an endemic and major health problem in Iran. The optimal treatment of OWCL is unknown, and current treatments are not ideally effective and have many adverse effects. To compare the efficacy and tolerability of combined oral azithromycin and allopurinol with intramuscular Glucantime in the treatment of OWCL, we conducted a prospective randomized clinical trial. A total of 86 patients with OWCL were assigned and divided randomly into two groups; they received a combination of azithromycin capsule 10 mg/kg/d and allopurinol tablet 10 mg/kg/d for two months or IM injection of Glucantime 20 mg/kg of antimony daily for 20 days. All patients were followed for two months after termination of treatment. Although immediately at the end of the treatment period, complete response was seen in 27.8% of patients on combination therapy vs. 0% in the Glucantime group. The combination of azithromycin and allopurinol had a better outcome; two months after the end of the treatment period, complete, partial, and no responses were seen in 38.9%, 22.2%, and 38.9% in combination therapy and 40%, 31.4%, and 28.6% in the Glucantime group. There was no significant difference between the response rate in both groups after two months (P = 0.5). No severe adverse effect occurred. This study demonstrated that the efficacy of combined oral azithromycin and allopurinol at the above doses and duration was similar to that of IM Glucantime in the treatment of OWCL.

Cutaneous leishmaniasis (CL) treatment is painful, and cosmetic results are often unsatisfying. Azithromycin has been reported to be effective in treatment of CL caused by Leishmania viannia braziliensis. The efficacy of azithromycin was compared with Glucantime in treatment of Old World leishmaniasis. Of 49 patients, 22 received 500 mg/day azithromycin for 5 days/month. Treatment cycles were repeated monthly to a maximum of 4 months; 27 patients received 60 mg/kg intramuscular meglumine antimoniate for 20 days. Both groups were followed up for 16 weeks. In the azithromycin group, 2 patients withdrew because of GI symptoms. The response rates of 20 patients (29 lesions) were as follows: full improvement, 10.3%; partial improvement, 27.6%; and 62.1%, no response. In the glucantime group with 27 patients (58 lesions), these rates were 34.4%, 13.8%, and 51.7%, respectively (P = 0.036). Azithromycin was determined to be not as effective as Glucantime in treatment of Old World CL.

Azithromycin was compared with meglumine antimoniate for treatment of patients with cutaneous leishmaniasis. Patients were randomized to receive oral azithromycin, 500 mg/day (22 patients) or intramuscular meglumine antimoniate, 10 mg Sb/kg/day (23 patients), both for 28 days, with a second cycle of 15 days if necessary, and followed-up for one year after completion of treatment. Efficacy, defined as complete re-epithelization without relapse for 12 months after completing therapy, was 82.6% (95% confidence interval [CI] = 67-98%) for meglumine antimoniate and 45.5% (95% CI = 25-66%) for azithromycin. All patients who failed treatment with azithromycin were treated with meglumine antimoniate and clinically cured. Azithromycin was well tolerated; meglumine antimoniate caused arthralgias and local symptoms in 78% of the patients. In 17 cases, species identification was obtained; Leishmania (Viannia) braziliensis was identified in all of them. For the treatment of American cutaneous leishmaniasis caused by L. (V.) braziliensis, meglumine antimoniate is significatively more efficacious than azithromycin, which was clinically curative in almost half of the patients and well-tolerated.

In the present study, we reported the natural infection by Leishmania sp. in a domestic cat, in which the amastigote forms of the parasite were observed within a lesion on its ear-tip. Fragment of the lesion was obtained and cultured in NNN medium, and PCR-RFLP analysis of the isolated sample was performed, which revealed that the profile was compatible with Leishmania (L.) amazonensis. This is the first proven case of a cat infected by L. (L.) amazonensis reported in Belém city, Pará state, northern Brazil.
