Distribution of virulence genes and phylogenetics of uropathogenic Escherichia coli among urinary tract infection patients in Addis Ababa, Ethiopia.

BACKGROUND: Urinary tract infection (UTI) is a common cause of morbidity worldwide. Uropathogenic Escherichia coli (UPEC) bacteria are the major cause of urinary tract infections. UPEC strains derive from different phylogenetic groups and possess an arsenal of virulence factors that contribute to their ability to overcome different defense mechanisms and cause disease. The objective of this study was to identify phylogroup and virulence genes of UPEC among urinary tract infection patients. METHODS: A cross sectional study was conducted from January 1, 2017 to October 9, 2017. E. coli bacteria were isolated from UTI patients using culture and conventional biochemical tests. Identification of phylogroup and genes that encodes for virulence factors was done using multiplex polymerase chain reaction (PCR). Data was processed and analyzed with SPSS version16.0 and Epi-info version 3.4.1 software. RESULTS: The most common urologic clinical manifestation combinations in this study were dysuria, urine urgency and urgency incontinence. The frequent UPEC virulence gene identified was fimH 164 (82%), followed by aer 109 (54.5%), hly 103 (51.5%), pap 59 (29.5%), cnf 58 (29%), sfa 50 (25%) and afa 24 (12%).There was significant association between pap gene and urine urgency (p-0.016); sfa and dysuria and urine urgency (p-0.019 and p-0.043 respectively); hly and suprapubic pain (p-0.002); aer and suprapubic pain, flank pain and fever (p-0.017, p-0.040, p-0.029 respectively). Majority of E. coli isolates were phylogroup B2 60(30%) followed by D 55(27.5%), B1 48(24%) and A 37(18.5%). There was significant association between E. coli phylogroup B2 and three virulence genes namely afa, pap, and sfa (p-0.014, p-0.002, p-0.004 respectively). CONCLUSION: In this study the most frequent E. coli virulence gene was fimH, followed by aer, hly, pap, cnf, sfa and afa respectively. There was significant association between E. coli virulence genes and clinical symptoms of UTI. The phylogenetic analysis indicates majority of uropathogenic E. coli isolates were phylogroup B2 followed by phylogroup D. Phylogroup B2 carries more virulence genes. Hence, targeting major UPEC phylogroup and virulence genes for potential vaccine candidates is essential for better management of UTI and further research has to be conducted in this area.

Depression and social support among breast cancer patients in Addis Ababa, Ethiopia.

BACKGROUND: Depression is a common co-morbid, disabling disorder that affects 10-25% of cancer patients. It causes substantial functional impairment and lowers survival rate of breast cancer patients. Therefore, the aim of this study is to determine the magnitude of depression and its association with social support among breast cancer patients in Addis Ababa, Ethiopia. METHODS: A cross-sectional study which included 428 breast cancer patients was conducted in seven health facilities in Addis Ababa, Ethiopia. Depression and Social Support were assessed using standard tools Patient Health Questionnaire 9 (PHQ 9) and Multidimensional Scale of Perceived Social Support (MSPSS) respectively. Descriptive statistics were done based on the standard PHQ9 cut off points (0-4, 5-9, 10-14, 15-19 and ≥ 20). Mann-Whitney and Kruskal Wallis tests were employed to compare MSPSS score among depressed and non-depressed patients and across the different levels of depression. Bivariate and multivariate logistic regression was done to identify factors associated with depression. RESULT: The prevalence of depression among breast cancer patients was 25% (107/428), andaccording to the PHQ9 score categorization, 70/428 (16.4%), 30/428 (7.01%) and 7/428 (1.64%) of these patients were having moderate, moderately severe and severe depression respectively. Age, occupation, type of health facility treated, severity of pain, hormonal therapy and having problem with employer/ family were significantly associated with depression. The participants' MSPSS total score was overall found to be high (70.35 ± 16.81). Those women who had moderate and severe depression had lower mean MSPSS scores compared to women with none/ minimal depression (P = 0.002). CONCLUSION: This study found that one in four breast cancer patients had depression. Depression is associated with poor social support given by family, friends and significant others. Therefore, screening for depression and psychosocial service should be integrated in the routine breast cancer care in Ethiopia.

Bacteremic Community-Acquired Pneumonia in Ethiopian Children: Etiology, Antibiotic Resistance, Risk Factors, and Clinical Outcome.

BACKGROUND: Community-acquired pneumonia (CAP) remains a leading cause of morbidity and mortality. We sought to determine the magnitude, etiology, and risk factors of CAP in children 5 years after introduction of pneumococcal conjugate vaccine (PCV) 10 in Ethiopia. METHODS: We conducted a prospective observational study on the bacterial etiology and risk factors of CAP among children aged 0-15 years in 2 pediatric emergency departments in Addis Ababa, Ethiopia. Blood culture, antibiotic susceptibility testing, and amplification of pneumococcal lytA and cpsB genes were performed. Serotypes of Streptococcus pneumoniae were determined by Quellung reaction and sequencing the cpsB gene. RESULTS: Out of 643 eligible children, 549 were enrolled. The prevalence of bacteremic pneumonia was 5.6%. Staphylococcus aureus (26.5%) was the predominant pathogenic species, followed by Enterococcus faecium (11.8%), Escherichia coli (11.8%), and Klebsiella pneumoniae (11.8%). In univariate analysis, parental smoking and nonvaccination with PCV10 were associated with bacteremic CAP. In multivariable analysis, female sex (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.1-4.9), weight-for-age z-score (WAZ) <-2 SDs (aOR, 2.2; 95% CI, 1.1-4.8), and lower chest indrawing (aOR, 0.44; 95% CI, 0.2-0.95) were independently associated with bacteremic CAP. The overall in-hospital case fatality rate was 2.37% (13/549), and WAZ <-3 SDs (OR, 13.5; 95% CI, 3.95-46.12) was associated with mortality. CONCLUSIONS: Five years after the introduction of PCV10 in Ethiopia, S. aureus was the main cause of bacteremic CAP in children, the contribution of S. pneumoniae was low, and there was a high level of antibiotic resistance among isolates.

FACTORS ASSOCIATED WITH TREATMENT OUTCOME OF PEDIATRIC CANCERPATIENTS ADMITTED WITH FEBRILE NEUTROPENIA IN TIKURANBESSA SPECIALIZED TEACHING HOSPITAL, ADDIS ABABA, ETHIOPIA.

Background: Cancer treatment is associated with variable degrees of myelosupression. Infection is often a life-threatening complication of chemotherapy-induced neutropenia, and it is also considered an oncologic emergency. Febrile neutropenia is a common, costly and potentially fatal complication in oncology. Objective: To assess factors affecting treatment outcome of cancer patients with chemotherapy induced febrile neutropenia. Method: We conducted a review of records of pediatric patients hospitalized and treated for chemotherapy-induced febrile neutropenia from January 1, 2013 to December 31, 2013 and met the selection criteria. Result: A total of 60 patients (36 males and 24 females) fulfilled the selection criteria. Twelve of them died while in hospital. The mean (SD) age of patients who died was 4.78 (±2.48) years and the mean (SD) hospital stay before death was 20.2 (±5.26) days. Ten children had hematologic malignancy and two had a solid tumor. Ten of the 12 patients had an absolute neutrophil count of less than 100/mm3 (p=0.008, OR=20.3) and a platelet count of less than 50,000/mm3. Six of the 10 children (10%) had sepsis. Patients with profound neutropenia, platelet count of less than 50,000 and sepsis were more likely to die (P=0.048, OR=7). Conclusion: The result of this study showed that absolute neutrophil count of less than 100/mm3, platelet count of less than 50,000/mm3 and a diagnosis of sepsis were factors affecting outcome patients with febrile neutropenia. Careful evaluation of these factors and assessing severity of patients' clinical condition at time of admission can be useful for triaging children with febrile neutropenia.

Frontal Lobe Tuberculoma: A Clinical and Imaging Challenge.

BACKGROUND: Pediatric nervous system tuberculomas are usually infra-tentorial and multiple. A frontal lobe location is rare. CASE DETAILS: We report a 10 year-old boy who presented with a chronic headache and episodes of loss of consciousness. He had no signs of primary pulmonary tuberculosis and a diagnosis of frontal tuberculoma was made upon a post-operative biopsy. He improved following treatment with anti-tubercular drugs. CONCLUSION: Tuberculosis should be considered in children with a chronic headache or focal neurologic deficit and a supra-tentorial intracranial mass in endemic countries like Ethiopia.

Tuberculous Dactylitis: An Uncommon Presentation of Skeletal Tuberculosis.

BACKGROUND: Skeletal involvement accounts 1-5% of all cases of Tuberculosis. The vertebrae are more commonly affected. The bones of the hands are more affected than the bones of the feet. The term "spina ventosa" has been used to describe this disorder because of its radiographic features of cystic expansion of the involved short tubular bones. Tuberculous dactylitis mainly occurs through lympho-hematogenous spread. The lung is the primary focus in 75% of cases. CASE DETAILS: A 4 years old female child developed a painless swelling on her left index finger two months prior to her presentation. Following an unsuccessful treatment as a case of osteomyelitis with antibiotics, imaging showed an expansile lytic lesion with sclerosis, and fine needle aspiration confirmed tuberculous dactylitis. The child was initiated on anti-tubercular treatment with subsequent marked clinical and radiologic improvement. CONCLUSION: Presence of longstanding finger swelling and pain should alert a clinician to consider active disseminated tuberculosis. Furthermore, proper interpretation of imaging and use of fine needle aspiration has been highlighted.
