Trichomonas vaginalis infection is one of the sexually transmitted diseases. It is a health problem all over the world, including Iraq. It has also been associated with adverse outcomes of pregnancy and increased risk of HIV. Trichomoniasis typically elicits aggressive local cellular immune responses with inflammation of the vaginal epithelium and exocervix in women and urethra in men. The present study was aimed to assess serum level of interferon gamma (IFN-γ), Interleukin 10 (IL-10), C-reactive protein, antiphospholipid, anticardiolipin antibodies with eosinophil count as well. Four hundred and forty women with ages ranging between 16 and 60 years old (average of 34.2 years) who attended Maternity Teaching Hospital and a number of public health centers in Erbil Governorate were screened for trichomoniasis by direct wet mount preparation and culture technique. Serum IFN-γ, IL-10, antiphospholipid, and anticardiolipin were assessed by enzyme-linked immunosorbent assay. C-reactive protein (CRP) and eosinophil count were assessed by I CROMA and Coulter, respectively. The results revealed that IL-10 level (96.46 ± 1.97 pg/ml vs. 91.86 ± 1.48 pg/ml), eosinophil count (0.1 ± 0.07 × 10³/μL vs. 0.1 ± 0.01 × 10³/μL), and CRP concentration (2.55 ± 0.74 mg/l vs. 2.27 ± 0.37 mg/l) were non-significantly (P > 0.05) changed in infected women in comparison with negative control group. However, serum IFN-γ level (484.83 ± 38.35 pg/ml vs. 372.15 ± 9.49 pg/ml) was significantly (P < 0.05) elevated in infected women in comparison to the control group. The results also revealed significant increase (P < 0.05) of antiphospholipid immunoglobulin G (IgG) antibodies (4.75 ± 0.3 U/ml vs. 3.79 ± 0.11 U/ml) in the sera of infected women, but antiphospholipid immunoglobulin M (IgM), anticardiolipin IgG, and anticardiolipin IgM antibodies were non-significantly altered in response to T. vaginalis infection.
Background and objectives: Echinococcus granulosus exists as a complex of different strains that differ in a wide variety of criteria that impact on the epidemiology, immunology, pathology and control of hydatid disease. This study was undertaken to investigate both humoral and cellular immune responses that are developed against hydatid cysts in Erbil. Methods: Thirty patients (9 males and 21 female) with surgically confirmed cystic echinococcosis and 10 apparently healthy individuals were included in this study. IgG ELISA was performed to asses humoral immune responses. CD4/ CD8 ratio, eosinophil count and lymphocyte transformation response were done to asses the cellular immune responses. The level of IFN-γ and TNF-α was also assayed. Results: The sensitivity of ELISA to detect anti-hydatid antibodies was shown to be 83.33%. CD4 / CD8 ratio was significantly (P< 0.001) decreased in patients with cystic echinococcosis as compared to normal control group, while eosinophil count (P< 0.001), lymphocyte transformation response (P< 0.001) and IFN-γ level (P< 0.01) were significantly increased. In contrast the level of TNFα was non- significantly changed in echinococcosis patients. Conclusion: The current study showed that the local strain of Echinococcus granulosus induces both cellular and humoral immune responses, and the number of peripheral blood CD8 T cells was significantly increased in cystic echinococcosis patients. However, hyporesponsivness to hydatid specific antigens has not been induced.
ABSTRAK (11,7%). Puncak infeksi terjadi selama musim semi 9 (65,9% vs 14,1%, p<0,05). ,5%). Tingkat deteksi rotavirus (32,0%) sedikit lebih tinggi pada laki-laki (34,4% vs 30,0%) dan anak usia 1 sampai 3 tahun (39,3%). Tingkat deteksi tertinggi (38,6%) terjadi selama musim dingin (Januari dan Februari). Infeksi lebih tinggi bermakna pada anak yang tidak divaksin Kesimpulan: Insidens cryptosporidiosis mengalami penurunan tetapi gastroenteritis akibat rotavirus cukup banyak terjadi pada anak-anak di Erbil. Vaksin rotavirus menurunkan insidens infeksiakibat rotavirus secara bermakna. ABSTRACTBackground: Watery diarrhea is the most common medical problem among infants and young children, caused by different microbial etiology including Cryptosporidium spp. and rotavirus, which are usually misdiagnosed in conventional stool test. This study aimed to investigate the incidence of Cryptosporidium and rotavirus gastroenteritis among children in Erbil as well as evaluate the efficacy of rotavirus vaccination procedure applied in Erbil.
Helicobacter pylori is resident in human stomach and causes chronic disease (peptic ulcer and gastritis). The mouth and colon were both known to host a large number of microbes. This study was carried out to investigate the seroprevalence of H. pylori infection among Cihan University students. A total of 197 blood samples were collected from the students (53 females and 144 males) from 13 departments of Cihan University, Erbil, and tested for anti-H. pylori antibodies, using rapid immunochromatography assay. Among 197 students tested, 44 (22.3%) showed positive reaction for H. pylori, 32 males and 12 females. It was non-significantly higher among students with ages ranged between 29 and 32 years old. Twenty-one of infected students were using tap water for drinking. Twenty-six (59.1%) of positive students experienced no symptoms and 18 (40.9%) were symptomatic (13.63% epigastric pain and 27.2% abdominal pain).
Diagnosis of cystic echinococcosis is complex and has to be confirmed by the combination of immunological tests and imaging techniques. In this study heat shock proteins were induced and their immunoreactivity was assessed by ELISA. Sera were collected from 34 hydatid patients who were admitted to the Rizgary Teaching Hospital through October 2013 to July 2017, in addition to 29 healthy donors and 18 non-hydatid cases. For heat shock response, two batches of 25000 protoscoleces (Ps) were incubated separately at 42°C and 45 °C for 4 hours. Heat treated and normal Ps were disrupted and the extracts were divided into two parts. One part was directly used as source of antigens (PE, PE42 and PE45) and the other one was partially purified on Sephadex G150. The immunoreactivity of these antigens, as well as hydatid fluidwas assessed by ELISA. The cutoff value to differentiate positive from negative sera was established by receiver operating characteristic (ROC) analysis. Two peaks of PE42 and three peaks of PE45 resulted by Sephadex G150. Extracts of 42ºC treated Ps resulted in two protein peaks and were used as PE42P1 and PE42P2 antigens. For 45°C treated Ps, the chromatography patterns resulted in three protein peaks and were used as PE45P1, PE45P2 and PE45P3 antigens. Highest rates of sensitivity, specificity and diagnostic accuracy were detected with PE42P2 (91.2%) and PE45P2 (91.2%). Sensitivity of ELISA was consistent for liver cysts with all applied antigens. Hydatid antigens extracted from heat treated Ps markedly raised the sensitivity of ELISA to detect anti-hydatid IgG.
