Human papillomavirus (HPV) genotype prevalence and impact of COVID-19 on the HPV prevention program in Duhok city.

Introduction and aims: Human papillomavirus (HPV) is a sexually transmitted virus that can cause cervical cancer. This study aimed to investigate the prevalence of HPV infection, the prevalent HPV genotypes in women and men with recurrent genital infections, and the impact of the coronavirus disease 2019 (COVID-19) pandemic on the HPV prevention program. Materials and methods: This cross-sectional study was conducted in Duhok city, in the Kurdistan Region of Iraq, between January 2018 and September 2020. We recruited patients from an infectious disease clinic, who were married, were older than 18 years, and agreed to participate in this study. A reverse hybridisation-based assay was used to identify the HPV genotypes prevalent in these patients. Results: Among the patients in the study, 20.9% (67/320) tested positive for HPV infection. The HPV prevalence in females was 18.8% (52/276), which was lower than that in males (34.1%,15/44) (p = 0.21). Thirty-six patients (11.3%) were infected with a single HPV genotype, seventeen (5.3%) with two HPV genotypes, eight (2.5%) with three HPV genotypes, and the remaining six (1.8%) with four or more HPV genotypes. The most common genotypes detected among the patients were HPV-6 (7.2%), -11 (3.8%), and -16 (3.4%). The prevalence of all HPV genotype infections was highest and lowest in the 18-25- and 36-45-year age groups, respectively (X 2 = 8.24; p = 0.041). The number of referred patients substantially reduced from 12 patients per month to 1 patient per month during the COVID-19 pandemic. Conclusion: HPV infection was common in the study population. The most common genotypes were HPV 6, 11, and 16, against which vaccines are available. Further population-based studies are needed to investigate the prevalence of such an infection.

A rare case of absolute thrombocytopaenia in a COVID-19 patient: Case report.

INTRODUCTION: Thrombocytopaenia, one of the most common haematological disorders worldwide, is characterised by platelet counts <150,000/mm3. Patients with coronavirus disease (COVID-19) were found to commonly exhibit haematological abnormalities, often with mild forms of thrombocytopaenia. Absolute thrombocytopaenia tends to be rare among these patients and is believed to be secondary to immune-induced thrombocytopaenia. CASE PRESENTATION: A 53-y-old man presented with fever and generalised body ache that persisted for a few days. His polymerase chain reaction test was positive for COVID-19, for which he was treated with acetaminophen, levofloxacin, and favipiravir. On the third day of treatment, he noticed bruising and bleeding, mainly in the oral cavity, with clot formation. A complete blood picture (CBP) revealed severe thrombocytopaenia with an almost-zero count. Prednisone 1 mg/kg/d and frequent doses of intravenous platelet transfusion were administered as rescue therapy to prevent fatal bleeding. The patient was able to recover. CLINICAL DISCUSSION: Immune thrombocytopaenia should be considered in patients presenting with bleeding tendencies after severe acute respiratory syndrome coronavirus 2 infection. Serial CBP is recommended for vulnerable patients, especially during the second and third weeks of hospitalisation, for the early detection and prevention of life-threatening COVID-19 complications. CONCLUSIONS: Absolute thrombocytopaenia is a rare condition. Such a condition should be considered in patients presenting with bleeding tendencies with severe Covid-19 infection. With early diagnosis and appropriate treatment, patients' lives can be saved.

Home management scheme for patients with severe covid-19 in Duhok city, Kurdistan region of Iraq: a possible role for family physicians.

AIM: This study investigated the clinical characteristics and outcomes of patients with severe coronavirus disease 2019 (COVID-19) who were involved in the home management scheme in Duhok city. MATERIALS AND METHODS: This prospective descriptive study enrolled Kurdish patients diagnosed with severe COVID-19 between June 1 and November 1, 2020, and were treated at home. RESULTS: The average age of the patients was 59.77 ± 14 years and 51 (56.04%) of them were males. Seven of these patients (7.69%) were smokers. Most patients (72.52%) had one or more comorbidities. Fever (87.1%) was the most commonly presented symptom in older patients. The case fatality rate was 3/91 (3.29%). This rate was not found to be associated with sex, history of smoking, or comorbidities. The age of deceased patients (40 ± 25 years) was significantly lower than that of cured patients (60 ± 13 years) (p = -0.025). CONCLUSIONS: The case fatality rate of patients enrolled in this scheme was comparable to those who received treatment in hospitals. Therefore, this scheme could provide a good alternative for treating patients with severe COVID-19 and family physicians could lead the scheme through the primary care network.

A sharp increase in the number of COVID-19 cases and case fatality rates after lifting the lockdown in Kurdistan region of Iraq.

With the appearance of first cases of Coronavirus disease (COVID-19), strict control measures were implemented in the Kurdistan Region of Iraq to combat the infection. These measures included the closure of schools and universities, the closure of borders and airports, cancellation of public and religious gatherings, and mandatory quarantine for persons returning from traveling abroad. Such measures have played a major role in the control of COVID-19 spread. However, due to social and economic pressures, the government relaxed the lockdown. After relaxing the measures, a sharp increase in the number of patients was noticed. Besides, there was a significant increase in the number of symptomatic patients and the case fatality rate was doubled. In addition, the outbreak and outbreak response led to the loss of trust and a breakdown in relations between the society and local authority. To minimize the consequences for population health, local authority should have a plan that balances between health imperatives and socioeconomic imperatives. Finally, to be successful in controlling the infection, the government must rebuild public trust in the handling of COVID-19 outbreak and compensate people for lost earnings.

Impact of Covid-19 pandemic on surgical practice in Kurdistan, Iraq: An online cross-sectional survey.

INTRODUCTION: The COVID-19 pandemic is a major challenge to healthcare services in the world. It has negatively impacted surgical practice, and health workers. We aimed to assess the impact of the COVID-19 pandemic on surgical practice in the Kurdistan Region, Iraq. METHODS: An online cross-sectional study using an online survey was performed between 13 April to 29 April, 2020 in the Kurdistan Region, Iraq. An online cross-sectional study using an online survey was performed between 13 April to 29 April, 2020 in the Kurdistan Region, Iraq. A total of 241 surgeons, aged 28-70 years (mean range 22.2 ± 7.9 SD), were recruited to this study. The questionnaire was designed to evaluate the impact of the COVID-19 pandemic on surgeons' practices. Participants completed a self-developed online questionnaire. RESULTS: The majority of participants (44.39%) were general surgeons, followed by urologists (17.01%). Approximately 82.57% of surgeons performed surgeries during the COVID-19 pandemic and 60.31% undertook emergency surgeries only. There was no significant difference between men and women (P = 0.41) and different age groups (P = 0.08). Only 28.22% of surgeons had access to full personal protective equipment (PPE), and 41.18% believed that wearing PPEs severely affected their skills. Results also found that surgeons aged between 28 and 34 years were more pledged to the use of PPEs, than other age groups (P = 0.001). The use of PPEs during surgeries was significantly higher in the Sulaymaniyah province (P = 0.001). The surgical services were also severely impacted in the Sulaymaniyah province than in the other provinces (p = 0.001). CONCLUSION: The COVID-19 pandemic severely affected surgical practice in the Kurdistan Region, particularly in the Sulaymaniyah province. Males, and young surgeons showed a higher commitment level for using PPE. Additional training and precautions are needed to increase awareness about COVID-19 among surgeons, and the importance of using PPE during surgery.

High Risk Human Papilloma Virus Genotypes in Kurdistan Region in Patients with Vaginal Discharge.

BACKGROUND: The human papilloma virus (HPV) is considered as the major risk factor for the development of cervical cancer. This virus is of different genotypes and generally can be classified into high and low risk types. OBJECTIVE: To determine the rate of high risk HPV genotypes in women with vaginal discharge and lower abdominal pain in Kurdistan region, Iraq. MATERIALS AND METHODS: Cervical swabs were taken from 104 women. DNA was extracted and the polymerase chain reaction (PCR) technique was used to determine the presence of high risk genotypes. RESULTS: It was found that 13/104 (12.5%) of the samples were positive for high risk HPV genotypes. Amongst those who were positive, 4/13 (30.7%) were typed as genotype 16 and 7/13 (53.8%) showed mixed genotyping. On the other hand, genotypes 53 and 56 were found in only one sample each. CONCLUSIONS: High risk HPV genotypes are not uncommon and further community based study is needed to determine the prevalence of HPV and its genotypes and plan for prevention of infection.

Helicobacter pylori vacA transcription is genetically-determined and stratifies the level of human gastric inflammation and atrophy.

AIMS: Helicobacter pylori infection is the major cause of peptic ulceration and gastric cancer, and an important virulence determinant is its vacuolating cytotoxin vacA. Previously, we have described allelic variation in vacA which determines toxin activity and disease risk. Here we aimed to quantify vacA mRNA expression in the human stomach, define its genetic determinants and assess how well it predicts gastric pathology. METHODS: Gastric biopsies were donated by 39 patients with H. pylori infection attending for endoscopy at Queen's Medical Centre, Nottingham, UK. Total RNA was extracted, and vacA mRNA quantified by reverse transcriptase quantitative PCR. Separate biopsies were histologically scored for inflammation and atrophy using the updated Sydney system. H. pylori strains were isolated from further biopsies, and the nucleotide sequence upstream of vacA determined. RESULTS: vacA mRNA levels in human stomachs varied by two orders of magnitude independently of vacA allelic type. Among vacA i1-type (toxic) strains, increased vacA expression was strongly associated with higher grade gastric inflammation (p<0.02), neutrophil infiltration (p<0.005) and the presence of atrophy (p<0.01). A polymorphism at nucleotide +28 near the base of a potential stem-loop structure within the 5' untranslated region was significantly associated with vacA transcript level and inflammation. CONCLUSIONS: Increased gastric vacA expression during H. pylori infection is associated with inflammation and premalignant pathology. The +28 nucleotide within the vacA 5' stem-loop stratifies disease risk among toxic vacA i1-type strains.

Vacuolating cytotoxin genotypes are strong markers of gastric cancer and duodenal ulcer-associated Helicobacter pylori strains: a matched case-control study.

The Helicobacter pylori virulence gene, cagA, and active forms of the vacuolating cytotoxin gene, vacA, are major determinants of pathogenesis. However, previous studies linking these factors to disease risk have often included patients using aspirin/nonsteroidal anti-inflammatory agents (NSAIDs) or acid-suppressing drugs, both of which may confound results. Also, particularly for gastric cancer (GC), controls have often been of quite different ages. Here, we performed a careful study in a "clean" Belgian population with gastric cancer cases age and sex matched to 4 controls and with a parallel duodenal ulcer (DU) group. As in other populations, there was a close association between the presence of cagA and the vacA s1 genotype. For GC, associations were found for vacA s1-positive (P = 0.01, odds ratio [OR], 9.37; 95% confidence interval [CI], 1.16 to 201.89), i1-positive (P = 0.003; OR, 12.08; 95% CI, 1.50 to 259.64), and cagA-positive status (P < 0.05; OR, infinity; 95% CI, 0.76 to infinity). For DU, associations were found with vacA s1 (P = 0.002; OR, 6.04; 95% CI, 1.52 to 27.87) and i1 (P = 0.004; OR, 4.35; 95% CI, 1.36 to 14.78) status but not with cagA status. Neither condition showed independent associations with the vacA m1 allele or with more biologically active forms of cagA with longer 3' variable regions. In this Belgian population, the best markers of gastric cancer- and duodenal ulcer-associated strains are the vacA s1 and i1 genotypes. This fits with experimental data showing that the s and i regions are the key determinants of vacuolating cytotoxin activity.

The distribution of cagA and dupA genes in Helicobacter pylori strains in Kurdistan region, northern Iraq.

BACKGROUND AND OBJECTIVES: Helicobacter pylori is a Gram negative bacteria that causes peptic ulceration and gastric adenocarcinoma. H pylori virulence factors, such as cagA and dupA, are important to study in populations as they contribute to disease risk. This study aimed to look at the distribution of the cagA and dupA genes in H pylori strains isolated from patients suffering from gastroduodenal diseases in Kurdistan region, Iraq. DESIGN AND SETTINGS: A cross-sectional study conducted between June 2011 and January 2012. Biopsies were collected from the Endoscopy Department in Duhok and Sulaimania hospitals, Kurdistan region, northern Iraq. PATIENTS AND METHODS: Upper gastrointestinal (GI) endoscopy examination was performed and 4 gastric biopsies (2 from the antrum and 2 from the corpus) were obtained from 204 patients. H pylori positivity was examined by CLO test; then the association between disease status and virulence factors was assessed by polymerase chain reaction. RESULTS: 154 (75%) of our samples were found to be H pylori + by CLO test. Endoscopic diagnoses for those who were positive were as follows: peptic ulcer disease (PUD) including duodenal ulcer, 45; gastric ulcer, 23; and no ulcer (NPUD), 86. The overall prevalence rates of cagA and dupA were 72.7% and 18.8%, respectively. While a significant association between cagA and PUD was observed (P. ≤.017; OR=0.4; CI=0.18­0.85), no relationship between dupA and PUD could be seen. CONCLUSION: These data suggested that the presence of cagA may be a predictor of clinical outcome in Kurdistan region, northern Iraq.

Intestinal obstruction secondary to primary ileocecal tuberculosis: A case report.

A 22-year-old Iraqi male presented with a case of intestinal obstruction secondary to primary ileocecal tuberculosis (TB). The presumptive diagnosis of either Crohn's disease or neoplasm was expected. A right hemicolectomy was performed. Histopathology revealed an inflammatory mass of TB origin; a polymerase chain reaction (PCR) confirmed the diagnosis. The patient was treated with standard anti-TB drugs for 6months. Following the treatment, the systemic symptoms disappeared and the laboratory investigations returned to normal. Follow-up period showed no recurrence of the disease.

A study of Helicobacter pylori outer-membrane proteins (hom) A and B in Iraq and Turkey.

Helicobacter pylori outer-membrane proteins (hom), especially the homB gene, have been suggested as a novel virulence factor. However, no study has been conducted in Middle Eastern countries regarding the association between these genes and clinical outcome. Gastric biopsies were obtained from 70 and 64 unselected H. pylori+ patients from Iraq and Turkey, respectively. PCR was performed to study the presence of the homA, homB, and cagA. No association was found between homA or homB and clinical outcomes. When Iraqi and Turkish strains were combined as Middle Eastern samples, cagA positivity was significantly higher in patients with peptic ulcer disease (PUD) than those with non-peptic ulcer disease (NPUD) (p=0.003, OR=3.6, CI=1.5-8.8). Two Iraqi strains showed intermediate, non-homA non-homB, length PCR products. The function of such gene is yet to be determined. In conclusion, hom genes might not be a good indicator for disease prediction in the Middle East. More studies are needed to confirm these results and determine the function of intermediate length hom.

Cancer incidence rates in the Kurdistan region/Iraq from 2007-2009.

Cancer is a disease of gradual increase in incidence overall the world. Kurdistan Region in Iraq has been exposed to several carcinogenic hazards. There are few reports about the increased risk of cancer in different cities in Iraq. These reports did not cover Kurdistan region. The aim of this paper was to study cancer incidence and to identify possible risks of cancer in this region. Cancer registries from 9 hospitals in three cities of Kurdistan were used as a source of data. Information on these cases was subjected to careful verification regarding repetition, place of residence and other possible errors. Overall registered cases in 2007, 2008 and 2009 were 1444, 2081, 2356 respectively. 49% of registered cases were males and 51% were female. The Age Standardized Rate of cancer was 89.83/100 000 among male and 83.93/100 000 among female. The results showed major variation in incidence rates of different types of cancer in the three governorates of Kurdistan. Furthermore, there was evidence of increased risks of cancer in Kurdistan Region in Iraq. Hematological malignancies were the most common cancer among male (21.13% of all cancer in males) and second most common in female (18.8% of all cancer in female), only exceeded by breast cancer. To reach sound conclusions about extent and determinants of cancer in Kurdistan, enormous multi-spectrum efforts are now needed.

Helicobacter pylori and gastric cancer in the Middle East: a new enigma?

The Middle East is the home of ethnic groups from three main backgrounds: Semitic (Arabs and Jews), Indo-European (Persians and Kurdish) and Turkic (Turkish and Turkmens). Its geographic location, which has been under continuous influences from Asia, Europe and Africa, has made it an ideal site for epidemiological studies on Helicobacter pylori (H. pylori) infection and genotyping. The gastric cancer rate differs in this region from very high in Iran (26.1/10(5)) to low in Israel (12.5/10(5)) and very low in Egypt (3.4/10(5)). Epidemiological studies showed that the prevalence of H. pylori is almost similar in those countries with a high level of infection in childhood. Importantly, the frequency of vacA s1 and m1 regions and cagA+ genotypes were higher in non Semitic populations who inhabit the North than Semitic populations, the inhabitants of Southern parts of the Middle East. H. pylori infection prevalence, distribution pattern of virulence factors, diet and smoking could not have explained the difference in cancer rate. This reflects the multifactorial aetiology of gastric cancer and suggests that H. pylori infection does not always directly correlate with the risk for gastrointestinal disease, such as gastric cancer. Further detailed investigations and international comparative studies of each risk factor need to be performed to investigate whether this represents a true enigma.

Helicobacter pylori dupA is polymorphic, and its active form induces proinflammatory cytokine secretion by mononuclear cells.

BACKGROUND: Infection with Helicobacter pylori possessing a newly described virulence factor--duodenal ulcer-promoting gene A (dupA)--has been associated with duodenal ulceration and increased gastric inflammation. METHODS: The dupA locus of 34 strains was sequenced. A panel of dupA mutants was generated and cocultured with human gastric epithelial cells and peripheral blood mononuclear cells; proinflammatory cytokine release was measured. IL8 expression was measured in human gastric biopsy specimens and related to the dupA and cagA status of infecting strains. RESULTS: Most H. pylori strains had a dupA allele that was longer (1884 bp; dupA1) than previously described dupA alleles, although some had truncated versions (dupA2). Unlike the best-characterized H. pylori virulence determinant, the cag pathogenicity island (cag PaI), neither dupA type induced release of interleukin (IL)-8 from gastric epithelial cells. However, infections due to dupA-positive strains were associated with higher-level mucosal IL-8 messenger RNA expression in the human stomach than were infections due to dupA-negative strains. To explain this paradox, we found that dupA1 (but not dupA2 or the cag PaI) substantially increased H. pylori-induced IL-12p40 and IL-12p70 production from CD14(+) mononuclear cells. Other T helper 1-associated cytokines were also modestly induced. CONCLUSION: We suggest that virulent H. pylori strains cause inflammation by stimulating epithelial cells through cag-encoded proteins and mononuclear inflammatory cells through dupA1 products.
