Pakistan's HIV high-risk populations: Critical appraisal of failure to curtail spread beyond key populations.

Pakistan has been a hub of several HIV outbreaks over the last 2 decades, with four major outbreaks being registered since 2018. There has been a recent rise in HIV infections, especially in high-risk populations, mainly consisting of people who inject drugs, men who have sex with men, prisoners, the transgender women community, and female sex workers. Consistently poor infection control practices, unregulated unsafe blood transfusion, questionable ethical practices by healthcare providers, and a general lack of awareness are the main drivers of recent HIV outbreaks, with these issues exacerbated by the presence of untrained health care providers. To stop the spread of HIV systemically and sustainably, aggressive measures need to be taken at all levels by all concerned stakeholders that not only deal with building up testing, tracing, and treatment capabilities but also address underlying grassroots problems that have largely been ignored to date.

Pathways to prevention: insights on stemming HIV outbreaks in Larkana, Pakistan.

In the past two decades, Pakistan has faced multiple human immunodeficiency virus outbreaks, with Larkana appearing to be the hub of such outbreaks. While the previous Larkana outbreaks happened in high-risk populations, the alarming outbreak in 2019 occurred in a low-risk paediatric population, raising several concerning questions. Human immunodeficiency virus infections spilling into the general population is indicative of a steady increase in the number of cases, and the failure of control strategies to stem the concentrated epidemic from evolving. Although several causative factors have been identified from previous outbreaks, the one that occurred in 2019 may have been influenced by an additional, hitherto unexplored factor; child sexual abuse. The current narrative review was planned to summarise human immunodeficiency virus risk factors and causes identified in previous Larkana epidemics, to explore potential reasons for the outbreaks in children, and to discuss possible steps needed for stemming human immunodeficiency virus outbreaks in Pakistan.

Review of sepsis in Pakistan: how far have we come?

Pakistan is a low-middle-income country (LMIC) with a high burden of sepsis, yet there is a profound dearth of data regarding sepsis with no comprehensive review. In Pakistan, access to competent healthcare services is delayed and in places, often not available. Patients may present with sepsis after common community-acquired infections; the commonest sources of sepsis are the respiratory tract followed by the urinary tract. Gram-negative organisms are responsible for a large majority of cases of sepsis. Unfortunately, compliance with sepsis guidelines remains poor, and sepsis-related statistics do not seem to be improving significantly. Adult sepsis presents a significant burden on healthcare services, particularly in LMICs, and is a leading cause of morbidity and mortality. Many factors which affect outcomes and cost of care are amenable to prompt interventions. Consequently, there is a dire need to make concentrated efforts in implementing simple, cost-effective, and context-specific guidelines and monitoring strategies regarding the diagnosis and management of sepsis. The collection and analysis of information on sepsis in Pakistan hence remains imperative, in order to prospectively assess the effects of guideline compliance on outcomes and to formulate and refine new schemata to address emerging problems.

SARS-CoV-2 induced coagulopathy and potential role of anticoagulation: Scoping review of literature.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can vary on a spectrum of asymptomatic disease to rarer manifestations like hypercoagulability especially among elderly patients admitted in the intensive care unit (ICU) and those with preexisting comorbidities. The exact mechanism behind this phenomenon is still unclear, however studies have shown an association with elevated cytokines and severe inflammatory response which encompasses this disease. Hypercoagulability can be limited to the lungs, or present as systemic manifestations of arterial and venous thrombosis leading to mortal outcomes. Thus, careful evaluation of risk factors should be performed by physicians and treatment with anticoagulants should be modified accordingly. All Coronavirus Disease 2019 (COVID-19) in-patients should receive thromboprophylactic therapy, with increased dosages administered to patients with increased disease severity or those with a high risk. D-dimer levels and sepsis-induced coagulopathy (SIC) score aid in identifying high risk patients and predicting outcome. This article highlights the pathophysiology behind hypercoagulability, its clinical associations and discusses therapeutic modalities to combat this fatal consequence of SARS-CoV-2.
