Abstract
Background and Aim: The heterogenous population of memory T lymphocytes is distinguished based on surface markers and effector functions such as cytokine secretion. Recently, two subsets of memory T cells are defined by expression of chemokine receptor CCR7 and CD45RA designating as "central memory" T cells (TCM) and "effector memory" T cells (TEM). The objective of this staudy was to evaluate the phenotype and function of these lymphocytes in healed cases of cutaneous leishmaniasis.
Methods: The phenotype of lymphocytes were determined in blood samples of 13 volunteers with history of self healing cutaneous leishmaniasis (HCL) and in 6 healthy controls.
Results: No significant difference was found in memory T cell subsets between HCL volunteers and healthy controls using flow cytometry. However, following sorting of different memory subsets, a significantly higher proliferation was seen in cells of HCL volunteers comparing to the control group. A significantly higher IFN-γ response in TEM and a significantly higher IL-2 response in TCM were observed in cell culture of HCL volunteers comparing controls.
Conclusion: The responses were elicited when the cells were stimulate with SLA in vitro, it is concluded Leishmania-specific TEM and Leishmania-specific TCM subsets exist in HCL volunteers and since the volunteers with history of CL presumed to be protected against reinfection, it seems that both TCM and TEM play role in the protection against Leishmania infection in these individuals.

Abstract
Leishmaniasis is a neglected disease caused by different Leishmania species and transmitted by various sand flies. Iran is endemic to both visceral and cutaneous form of the diseases. The aim of this study was to investigate the epidemiological factors of leishmaniasis in patients referred to the Center for Research and Training Skin Disease and Leprosy from 1399-1400. The present study is a cross-sectional study in which every patient with suspected cutaneous leishmaniasis lesion(s) referred to the center during 1399-1400 were included. The results showed a higher number of patients with leishmaniasis are in the age group of 10 to 19 years. Among the mentioned jobs, a higher percentage was assigned to housewives in the affected women and workers in the affected men. According to the results, autumn is the most common season for cutaneous leishmaniasis. The average time from beginning to the diagnosis of leishmaniasis was 1.5-3 months and most patients showed a history of traveling to rural areas. The number of wet type lesions were higher than dry type and most of the lesions were in the hands. Most cases were reported from Isfahan province.

Abstract
Background and Aim: Leishmaniasis is a parasitic disease transmitted by sandflies and is one of the endemic diseases of Iran. With the spread of the Covid-19 epidemic worldwide, the virus will interface with endemic infectious diseases in different regions. In this study, coronavirus disease was evaluated in patients with a history of leishmaniasis referred to the Center of Research and Training in Skin Diseases and Leprosy.
Methods: A total of 91 patients with a history of leishmaniasis were studied for possible SARS-CoV-2 infection. The number of patients referred to the Center of Research and Training in Skin Diseases and Leprosy during the coronavirus epidemic was also compared with the same period before the epidemic
Results: A total of 60% of patients with leishmaniasis
did not report coronavirus disease. Twenty-one percent of cases had a mild corona disease, 13% had a moderate and 3% had severe corona disease. Only a single death was reported in corona patients with a history of cutaneous leishmaniasis. The number of referrals before the beginning of the corona epidemic was twice as high as during the epidemic.
Conclusion: In these participants, mortality and side effects of COVID-19 were significantly less reported. However, further studies are needed to evaluate the immune system and cutaneous leishmaniasis protection against COVID-19. Various factors can be effective in reducing patients during the epidemic, including not going to medical centers, reducing the number of trips, and observance of health issues.

Abstract
Background and Aim: Cutaneous leishmaniasis is one of the most important health problems in Iran. There is still no effective vaccine available against human leishmaniasis and current treatment is based on chemotherapy. Conventional drugs are toxic and expensive, and drug resistance has caused the search for new treatments. Tofacitinib is a Janus kinase inhibitor that disturbs the signaling pathway of several cytokines in the immune system. The aim of this study was to evalute the effect of topical tofacitinib 2% ointment in healing cutaneous leishmaniasis in Balb/C mice.
Methods: This experimental study was performed using tofacitinib and glucantim drugs in 40 female Balb/C mice. The metacyclic form of promastigote of Leishmania major standard strain (MRHO/IR/75/ER) was injected into the footpad of the mice, the mice were divided into 4 treatment groups: tofacitinib, glucantim, tofacitinib-glucantim and control without treatment. The treatment period was 28 days. The footpad thickness of all groups was measured at the end of each week.
Results: After the end of the treatment in the groups treated with tofacitinib, a significant decrease in the size of lesion and the footpad thickness was observed compared to the control group without treatment (P<0.01).
Conclusion: It seems that tofacitinib ointment accelerates lesion healing in Balb/C mice and has worked similarly to standard glucantim treatment. Ointment can be a better option for leishmaniasis treatment and due to its ease of use and no need for painful injections it can be considered as an option for the treatment of patients with cutaneous leishmaniasis.
