ABSTRACT

It has been emphasized that prurigo simplex subacuta may be associated with various disorders and may be clinically confused with dermatitis herpetiformis. Aim of the study was to evaluate the value of our set of tests for finding possible associations and for the aforementioned differential diagnosis. Rates of implementations and abnormal results in our set of tests, including skin prick test, skin biopsy, complete blood count, blood chemistry panel, and psychiatric evaluation were analyzed retrospectively between the years of 2010 and 2015 in 130 patients clinically diagnosed with prurigo simplex subacuta. The set of tests was implemented completely in 43.8% patients and with only a single missing test in 31.5% of the patients. The least implemented procedure was psychiatric evaluation (66.9%). The most commonly found issues were psychiatric abnormalities (55.2% of 87 psychiatrically evaluated patients) and atopy (53.8% of 104 skin prick tested patients). The most common finding suggestive of internal diseases was hyperglycemia (25.4% of 130 patients). It was a striking result that hematological malignancies were suspected upon complete blood count and peripheral blood smear and confirmed by further investigations in 4 of 102 patients. Dermatitis herpetiformis was diagnosed in 2 of 120 skin biopsied patients. Because of the substantial rate of implementation, the high frequencies of psychiatric abnormalities and atopy, and detection of hematological malignancies and dermatitis herpetiformis even in just a few patients, we recommend our set of tests for patients clinically diagnosed as prurigo simplex subacuta.

ABSTRACT

BACKGROUND: Both performer- and device-dependent variabilities have been reported in sizes of wheal responses to skin prick tests. OBJECTIVE: We aimed to evaluate whether or not variabilities in sizes of wheal responses influence the final interpretation of skin prick tests; in other words, the decision on whether or not there is an allergy to a given antigen. METHODS: Skin prick tests with positive and negative controls and extracts of Dermatophagoides farinae and Dermatophagoides pteronyssinus were done for 69 patients by two different persons, using two different puncturing devices- disposable 22-gauge hypodermic needles and metal lancets. RESULTS: Among four different skin prick tests, the average coefficients of variation in sizes of wheal responses were near to or higher than 20% for all of them. On the other hand, in the final interpretation of results, kappa values indicated substantial or almost perfect agreements between these tests. However, the frequency of establishing allergy to the house dust mites widely ranged in these tests (20.8-35.8% for D. farinae and 20.8-28.3% for D. pteronyssinus). LIMITATIONS: The conduction of the study in a single center and the comparisons of results of only two performers. CONCLUSION: We feel that variabilities in sizes of wheal responses of skin prick test can influence its categorical results.

ABSTRACT

OBJECTIVE: To report isolation of Leishmania major strains obtained from 18 Turkish autochthonous cutaneous leishmaniasis (CL) patients infected with L. major between 2011 and 2014. METHODS: Initial diagnosis relied on microscopy and culture in enriched medium, prepared by adding specific amounts of liver extract, protein and lipid sources to NNN medium. Promastigotes were then transferred to RPMI medium including 10% of foetal calf serum for mass culture. Species-specific real-time PCR targeting ITS1 region of Leishmania spp. was performed using both lesion aspiration samples and cultured promastigotes. Two of 18 isolates were identified by isoenzyme analysis in the Leishmaniasis Reference Center in Montpellier, France. Each isolate was inoculated into the footpads of six mice to observe the pathogenicity of L. major. Developing lesions were observed, and the thickening of footpads was measured weekly. RESULTS: Melting curve analyses of 18 isolates showed a peak concordant with L. major, and two of them were confirmed by isoenzyme analyses as L. major zymodeme MON103. In the mouse model, acute lesions seen on day 21 were accepted as an indication of heavy infection. Severe impairments were observed on all mouse footpads over 3 weeks, which even progressed to extremity amputation. CONCLUSION: Cutaneous leishmaniasis-causing L. major was recently identified in Adana province in southern Turkey, with PCR. Our study shows that such CL cases are not limited to Adana but currently present from western to Southeastern Anatolia, and along the Mediterranean coast. The role of small mammals, the main reservoirs of L. major in Anatolia, needs to be elucidated, as do the underlying factors that cause severe clinical manifestations in L. major infections in Turkey, contrary to the infections in neighbouring countries.
