Pathology, East Africa

Background: The emergence of carbapenem-resistant Acinetobacter baumannii (CRAB) was observed in a Kenyan hospital from 2009 to 2010. Further investigation of the dissemination of CRAB isolates and the molecular characterization of associated resistance determinants were therefore performed.

Methods: Antibiotic susceptibilities were determined by broth microdilution and Etest. Metallo-blactamases were detected by Etest method. Clonal relationships were studied by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). b-Lactam and aminoglycoside resistance determinants and the clonal relatedness to widespread European clones were studied by PCR and sequencing.

Results: Sixteen CRAB isolates from 10 patients possessed six pulsotypes; half of the isolates …

High Hiv Incidence Among Persons Who Inject Drugs In Pakistan: Greater Risk With Needle Sharing And Injecting Frequently Among The Homeless., Rab Nawaz Samo, Arshad Altaf, Ajmal Agha, Omrana Pasha, Shafquat Rozi, Ashraf Memon, Saleem Azam, Meridith Blevins, Sten Vermund, Sharaf Ali Shah

Community Health Sciences

BACKGROUND:

The incidence of HIV among persons who inject drugs (PWIDU) has fallen in many nations, likely due to successes of clean needle/syringe exchange and substance abuse treatment and service programs. However in Pakistan, prevalence rates for PWID have risen dramatically. In several cities, prevalence exceeded 20% by 2009 compared to a 2003 baseline of just 0.5%. However, no cohort study of PWID has ever been conducted.

METHODS:

We enrolled a cohort of 636 HIV seronegative PWID registered with three drop-in centers that focus on risk reduction and basic social services in Karachi. Recruitment began in 2009 (March to June) …

Tumor Necrosis Factor -Α, Interleukin-10, Intercellular And Vascular Adhesion Molecules Are Possible Biomarkers Of Disease Severity In Complicated Plasmodium Vivax Isolates From Pakistan., Afsheen Raza, Najia K. Ghanchi, Ali Bin Sarwar Zubairi, Ahmed Raheem, Sobia Nizami, Mohammad Asim Beg

Department of Medicine

Background: Cytokine-mediated endothelial activation pathway is a known mechanism of pathogenesis employed by Plasmodium falciparum to induce severe disease symptoms in human host. Though considered benign, complicated cases of Plasmodium vivax are being reported worldwide and from Pakistan. It has been hypothesized that P.vivax utilizes similar mechanism of pathogenesis, as that of P.falciparum for manifestations of severe malaria. Therefore, the main objective of this study was to characterize the role of cytokines and endothelial activation markers in complicated Plasmodium vivax isolates from Pakistan.

Methods and Principle Findings: A case control study using plasma samples from well-characterized groups suffering from P.vivax …

Background: Nodular lung disease is a rare presentation of sarcoidosis. Radiologically it can present as multiple pulmonary masses or solitary lung nodule.

Case presentation: We report three cases of nodular sarcoidosis in young females of Asian origin who had initially presented with dry cough and worsening dyspnea non-responsive to initially administered antibiotics. Pulmonary nodules were discovered upon radiographic imaging in all three cases which raised concern for the possibility of neoplastic processes. Subsequent biopsies revealed granulomatous inflammation indicative of sarcoidosis. All cases responded very well to systemic corticosteroids.

Conclusion: Sarcoidosis may present as nodular infiltrates which alerts the treating physician …

A Study On The Geophylogeny Of Clinical And Environmental Vibrio Cholerae In Kenya, J. Kiiru, A. Mutreja, A. A. Mohamed, R. W. Kimani, J. Mwituria, R. O. Sanaya, J. Muyodi, Gunturu Revathi, J. Parkhill, N. Thomson, G. Dougan, S. Kariuki

Pathology, East Africa

Cholera remains a significant public health challenge in many sub-Saharan countries including Kenya. We have performed a combination of phylogenetic and phenotypic analysis based on whole genome DNA sequences derived from 40 environmental and 57 clinical V. cholerae from different regions of Kenya isolated between 2005 and 2010. Some environmental and all clinical isolates mapped back onto wave three of the monophyletic seventh pandemic V. cholerae El Tor phylogeny but other environmental isolates were phylogenetically very distinct. Thus, the genomes of the Kenyan V. cholerae O1 El Tor isolates are clonally related to other El Tor V. cholerae isolated elsewhere …

Mugo, Vanessa Tenet, Folkert J. Van Kemenade, Farzana S. Rana, Samah R. Sakr, Chris J.L.M. Meijer, Peter J.F. Snijders, Silvia Franceschi

Pathology, East Africa

HIV-positive women are infected with human papillomavirus (HPV) (especially with multiple types), and develop cervical intraepithelial neoplasia (CIN) and cervical cancer more frequently than HIV-negative women. We compared HPV DNA prevalence obtained using a GP5+/6+ PCR assay in cervical exfoliated cells to that in biopsies among 468 HIV-positive women from Nairobi, Kenya. HPV prevalence was higher in cells than biopsies and the difference was greatest in 94 women with a combination normal cytology/normal biopsy (prevalence ratio, PR = 3.7; 95% confidence interval, CI: 2.4-5.7). PR diminished with the increase in lesion severity (PR in 58 women with high-grade squamous intraepithelial …

Population Genetics And Drug Resistance Markers: An Essential For Malaria Surveillance In Pakistan, Afsheen Raza, Mohammad Asim Beg

Department of Pathology and Laboratory Medicine

Plasmodium (P.) vivax is the prevalent malarial species accounting for 70% of malaria cases in Pakistan. However, baseline epidemiological data on P. vivax population structure and drug resistance are lacking from Pakistan. For population structure studies, molecular genetic markers, circumsporozoite protein (csp) and merozoite surface protein-1 (msp-1) are considered useful as these play an important role in P. vivax survival under immune and environmental pressure. Furthermore, these genes have also been identified as suitable candidates for vaccine development. While efforts for effective vaccine are underway, anti-malarial agents remain the mainstay for control. Evidence of resistance against commonly used anti-malarial agents, …

Effect Of Mobile Phone Short Message Service On Adherence Rates To Antihypertensives At The Family Medicine Clinic, Barbara Karau

Master of Medicine in Internal Medicine

Background: Systemic arterial hypertension is the main modifiable risk factor for development of cardiovascular disease, which is the number one cause of death in high income countries and is increasingly becoming a cause of concern in Sub-Saharan Africa (1). Awareness, management and overall control of hypertension in Sub-Saharan Africa is poor (2,3). Poor control stems from various causes; one being patient non-adherence with medication, a factor amenable to modification. The use of mobile health for behavioural change from low resource settings is gaining widespread use in management of communicable diseases (4,6). Mobile phone has the potential to significantly influence patients …

Neuropathogenic Escherichia Coli K1 Does Not Exhibit Proteolytic Activities To Exert Its Pathogenicity, Junaid Iqbal, Mehak Rajan, Ruqaiyyah Siddiqu, Naveed Ahmed Khan

Department of Biological & Biomedical Sciences

Background: Proteases are well-known virulence factors that promote survival, pathogenesis and immune evasion of many pathogens. Several lines of evidence suggest that the blood-brain barrier permeability is a prerequisite in microbial invasion of the central nervous system. Because proteases are frequently associated with vascular permeability by targeting junctional proteins, here it is hypothesized that neuropathogenic Escherichia coli K1 exhibit proteolytic activities to exert its pathogenicity.
Methods: Zymographic assays were performed using collagen and gelatin as substrates. The lysates of whole E. coli K1 strain E44, or E. coli K-12 strain HB101 were tested for proteolytic activities. The conditioned media were …

Coital Frequency And Condom Use In Monogamous And Concurrent Sexual Relationships In Cape Town, South Africa, Wim Delva, Fei Meng, Roxanne Beauclair, Nele Deprez, Marleen Temmerman, Alex Welte, Niel Hens

Obstetrics and Gynaecology, East Africa

Introduction: A decreased frequency of unprotected sex during episodes of concurrent relationships may dramatically reduce the role of concurrency in accelerating the spread of HIV. Such a decrease could be the result of coital dilution - the reduction in per-partner coital frequency from additional partners - and/or increased condom use during concurrency. To study the effect of concurrency on the frequency of unprotected sex, we examined sexual behaviour data from three communities with high HIV prevalence around Cape Town, South Africa.

Methods: We conducted a cross-sectional survey from June 2011 to February 2012 using audio computer-assisted self-interviewing to reconstruct one-year …
