Exploring terminology for puerperal sepsis and its symptoms in urban Karachi, Pakistan to improve communication, care-seeking, and illness recognition.

Puerperal sepsis is an important cause of maternal morbidity and mortality in developing countries. Awareness of local terminology for its signs and symptoms may improve communication about this illness, what actions to take when symptoms appear, timely care seeking, and clinical outcomes. This formative research aimed to improve recognition and management of postpartum sepsis in Pakistan by eliciting local terms used for postpartum illnesses and symptoms. We conducted 32 in-depth interviews with recently delivered women, their relatives, traditional birth attendants, and health care providers to explore postpartum experiences. Terms for symptoms and illness are used interchangeably (i.e. bukhar, the Urdu word for fever), many variations exist for the same term, and gradations of severity for each term as not associated with different types of illnesses. The lack of a designated term for postpartum sepsis in Urdu delays care-seeking and proper diagnosis, particularly at the community level. Ideally, a common lexicon for symptoms and postpartum sepsis would be developed but this may not be feasible or appropriate given the nature of the Urdu language and local understandings of postpartum illness. These insights can inform how we approach educational campaigns, the development of clinical algorithms that focus on symptoms, and counselling protocols.

A Retrospective Study of Laboratory-Based Enteric Fever Surveillance, Pakistan, 2012-2014.

Introduction: The Surveillance for Enteric Fever in Asia Project (SEAP) is a multisite surveillance study designed to capture morbidity and mortality burden of enteric fever (typhoid and paratyphoid) in Bangladesh, Nepal, and Pakistan. We aim to describe enteric fever disease burden, severity of illness, and antimicrobial resistance trends in Pakistan. Methods: In this retrospective, cross-sectional study, laboratory records of hospitalized patients who received a blood culture in any of 3 Aga Khan University hospitals in Karachi and Hyderabad, Pakistan, from 2012 to 2014 were reviewed. A case was defined as having a positive blood culture for Salmonella Typhi (S. Typhi) or Salmonella Paratyphi (S. Paratyphi). Antimicrobial sensitivity patterns were characterized for all S. Typhi and S. Paratyphi isolates. Medical records were available for abstraction (demographics, clinical features, complications) only among hospitalized cases. Results: Of the 133017 blood cultures completed during the study period, 2872 (2%) were positive-1979 (69%) for S. Typhi and 893 (31%) for S. Paratyphi. Fluoroquinolone resistance was present in >90% of both the S. Typhi and the S. Paratyphi isolates; almost none of the isolates were resistant to cephalosporins. Multidrug resistance (resistance to ampicillin, chloramphenicol, and cotrimoxazole) was observed in 1035 (52%) S. Typhi isolates and 14 (2%) S. Paratyphi isolates. Among S. Typhi and S. Paratyphi isolates, 666 (23%) were linked to hospitalized patients with medical records. Of the 537 hospitalized S. Typhi cases, 280 (52%) were aged 5-15 years, 133 (25%) were aged 2-4 years, 114 (21%) were aged >15 years, and 10 (2%) were aged 0-1 years. Among the 129 hospitalized S. Paratyphi cases, 73 (57%) were aged >15 years, 41 (32%) were aged 5-15 years, 13 (10%) were aged 2-4 years, and 2 (2%) were aged 0-1 years. Significant differences in symptomology between S. Typhi and S. Paratyphi cases were observed for nausea/vomiting, diarrhea, loss of appetite, and headache. Leukopenia, thrombocytopenia, and encephalopathy were the most commonly reported complications among enteric fever cases. No deaths were reported. Conclusion: Evidence of high antimicrobial resistance levels and disease severity support the need for continued surveillance and improved diagnostics for typhoid. Further prospective studies on vaccination as a tool for prevention of enteric fever in Pakistan are needed to inform disease intervention strategies.

High heterotrophic counts in potable water and antimicrobial resistance among indicator organisms in two peri-urban communities of Karachi, Pakistan.

OBJECTIVE: Fecal contamination of potable water leads to unsafe water supply. Although many urban areas of large metropolitan cities receive safe water, peri-urban areas are often not monitored by public health authorities and water supply and quality remain unknown. We assessed microbiological quality and rates of antimicrobial resistance in viable indicator bacteria in two peri-urban communities of Karachi, Pakistan. Water samples were collected over 5 months (October 2015 to February 2016) from these peri-urban communities and samples were processed for microbiological quality as per Standing Committee of Analysts, United Kingdom and World Health Organization guidelines and criteria for drinking water. RESULTS: Both communities received unimproved water. Potable water samples collected from 100 households showed that 96% of samples were unsafe for consumption. Extended spectrum beta lactamases production was found in 29.2% of fecal indicator organisms (coliforms). Use of unimproved water sources and unsafe potable water quality in peri-urban Karachi deserve immediate attention and upgrade. The study is instrumental in attracting the attention of authorities to the state of water resources in peri-urban communities in Karachi with a view to influence improvement of services and effects on human health.
