Through this research, case studies were reviewed which reviewed the dermatology department at Tishreen University Hospital in Lattakia and specialized centers for leishmaniasis and parasitic diseases in Lattakia and Tartous governorates from the beg
inning of April 2018 until the end of December 2019. Where Syria is one of the areas endemic with cutaneous leishmaniasis, as we have noticed in recent years the number of skin infections has increased dramatically in all Syrian governorates, which has made leishmaniasis an important health problem that warrants study. In order to isolate and determine the type and strains of the parasite responsible for skin injuries in Syria, in order to develop a plan to combat this disease and limit its spread. Microscopy and transplantation methods are the gold standard for diagnosing cutaneous leishmaniasis, especially in poor areas where this disease is common. Through this study it was found that the age group most exposed to infection is between 16 - 40 years and that the highest incidence was among males. As for the distribution of skin lesions, the highest percentage was recorded on the face, upper and lower extremities.
The present study was performed on blood samples belong to 15 patients( 12 males,3
females) infected with cutaneous leishmaniasis, and their healing was also proved after
submitting local treatment. Study tests were performed on 2 stages, the first
after infection,
and the second two months at least after healing. Every patient was subject of the
following tests: total, and differential white blood cells count and hematocrit value. In
addition ,a study of the morphological changes of white blood cells was conducted.
This study was performed on blood samples of 60 people [21females, 39
males]which have visited the center of leishmaniasis in lattakia city, and their infection
with cutaneous leishmaniasis was confirmed. The people were divided into three age
gro
ups where each group contained 20 patients, the first group [10-18 years,3females and
17males], the second group [19-30 years,8 females,12males],and the third group [31-
50years,10 females and 10males]. The following tests were evaluated to each blood
sample: total white blood cell count, differential white blood cells count, hematocrit test,
and blood group type test.
The aim of this work was determining the role of
Protein kinase C (PKC) signaling pathway in apoptosis of
Leishmania tropica promastigotes, through studying effects of PKC
specific inhibitor Staurosporine (STS) on the parasite. Our results
showed
that treated L. tropica with Staurosporine was
enough to inhibit PKC pathway completely, while viability test
showed that the concentration of STS to inhibit cell growth by 50%
(IC50 = 2.146μM).
Leishmaniasis spreads in eighty-eight countries, including the Syrian Arab
Republic. This disease is caused by a protozoic parasite of the genus
Leishmania. Twenty-two species of leishmania were reported to be pathogenic
for human. The disease is
presented in three clinical forms: cutaneous,
mucocutaneous and visceral leishmaniasis. A set of methods for diagnosis and
identifying the type of parasite have been developed in order to give
appropriate treatment. These methods include isoenzyme analysis, serological
and immunological methods and DNA hybridization. The polymerase chain
reaction (PCR), using genomic or kinetoplastid DNA; provides an excellent tool
for diagnosis and characterization of leishmania species. In this work, the two
types of DNA were extracted in one step from cultured isolates taken from
patients. We have used kinetoplastid DNA and specific primers to determine
parasite species by PCR. These primers amplify species specific fragment. In
this study, we have determined that the causative species of the cutaneous
leishmaniasis in all patients was L.tropica.
