Cervical cancer in southern Malawi: A prospective analysis of presentation, management, and outcomes

Background: Malawi has the highest age standardised rate of cervical cancer in the world. This study describes the presentation, management and short-term outcomes of patients with newly diagnosed cervical cancer at Queen Elizabeth Central Hospital (QECH), in Southern Malawi.Methods: All patients with a new diagnosis of cervical cancer presenting to QECH between 1st January-1st July 2015 had demographic data, referral pathway, stage, histology and management prospectively recorded at presentation, and at two months after initial presentation.Results: 310 women presented with cervical cancer to QECH and 300 were included (mean age 44.9 years; HIV 47%), representing 8% of the estimated annual number of new presentations in Malawi. Mean age of patients with HIV was 6.9 years younger compared to those without HIV (p<0.05). 132 (44%) patients had stage 1 cervical cancer and 168 (56%) presented with more advanced disease (stage II-IV). There was a mean delay of 23.1 weeks between onset of symptoms and being seen by a clinician and a further 19 weeks before attending QECH. Most common management plans at initial consultation were: same day biopsy (n=112, 37.3%);, booking for curative surgery (n=76, 25.3%);, and referral to palliative care (n=93, 31%). At 2 months, 64 (57%) biopsies were reported, 31 (40.8%) operations were completed and 27 (29%) patients had attended the palliative clinic.Conclusions: Patients presenting with cervical cancer to QECH were young, with a high prevalence of HIV, and late stage disease. The lack of pathological and surgical capacity and the absence of radiotherapy severely limited the possibility of curative treatment. Access to quality palliative care remains an important component of management in low resource settings. Improving awareness of cervical cancer in the community, and better recognition and management within the health service, are important in reducing the cancer burden for women in Malawi

Assisted partner notification as a strategy to enhance Pre-Exposure Prophylaxis (PrEP) screening and uptake – results from a prospective cohort study in Lilongwe, Malawi

Background Pre-exposure prophylaxis (PrEP) prevents HIV acquisition but strategies are needed to improve uptake among high-risk groups. Assisted partner notification (aPN), proven for HIV case-finding, may expand PrEP services to sexual partners of sexually transmitted infection (STI) patients. While passive (index-led) partner notification for STI treatment receipt is standard, offering an assisted strategy may increase linkage to PrEP for HIV vulnerable partners who may otherwise be missed. This study explored the feasibility and outcomes of integrating aPN into PrEP programs at an STI clinic in Malawi. Methods Between March 2022 and January 2023, this prospective cohort study enrolled men and women presenting for STI services who were initiating PrEP (index PrEP user) and their referred sexual partners. Using World Health Organization-recommended aPN methods, recent (within last 6 months) sexual partners named by index participants were traced via phone or in-person. We assessed demographic characteristics of index participants and referred partners, tracing outcomes, and PrEP initiation among partners. Results 174 index PrEP user participants were enrolled, most were male (109/174; 63%) with median age of 27 years (IQR 22, 32). The 174 index participants were asked to provide contact information for their partners, 69 of whom did. These 69 participants named 101 sexual partners (57% female). Partners were named as primary partners (53%), casual partners (41%), or sex workers (6%). Tracing efforts were employed for 52 partners with phone tracing yielding a 57% contact success and physical tracing yielding a 10% contact success. 58 partners (including those not traced) presented at the clinic for screening. Most presenting partners were female (39/58; 67%) and the median age was 28 years (IQR 23, 31). Among the presenting partners, 34/58 were eligible for PrEP, and 31/34 (91%) initiated PrEP. 20 of 55 named partners who agreed to testing were HIV positive, with 20% of these newly diagnosed during PrEP screening. Conclusions aPN, including passive notification, effectively identifies and links at-risk partners of persons initiating PrEP to HIV prevention services, achieving high rates of PrEP uptake among eligible presenting partners, though less than half of index PrEP users named partners for tracing. Notably, phone tracing was more effective than physical tracing, but phone number availability was limited. This study highlights the potential of aPN in expanding PrEP access and strengthening HIV prevention efforts among persons seeking STI services.Trial registrationThis trial is registered on 5 October, 2023 at ClinicalTrials.gov NCT05307991

Geospatial and phylogenetic clustering of acute and recent HIV infections in Lilongwe, Malawi

HIV transmission during early HIV infection impedes efforts to end HIV as a public health threat, as diagnosis typically occurs after this period of elevated transmission risk. To guide diagnosis and prevention strategies, we evaluated the geospatial and phylogenetic clustering of acute and recent HIV infection in Lilongwe, Malawi. We identified people with acute (pre-seroconversion) HIV infection (AHI) and a random sample of people with post-acute HIV infection who presented to a sexually transmitted infections (STI) clinic in Lilongwe, Malawi between 2015 and 2019. We evaluated infection recency in people with post-acute HIV using a LAg-Avidity assay. We mapped the household locations of people with AHI and identified geospatial clusters using a flexible scan statistic. We constructed consensus sequences from deep sequencing reads to identify phylogenetic clusters through genetic distance thresholds and maximum likelihood trees. We identified 141 people with AHI, 30 people with recent HIV, and 652 people with chronic (non-recent) HIV. We identified four geospatial clusters that contained the residences of 30% of clinic attendees with AHI, despite comprising just 0.8% of the populated land area and 3.5% of the population. We also identified fourteen distinct two-person phylogenetic clusters. Ten of the fourteen were male-female pairs, nine of which were clinic referral pairs. The remaining four were same-sex pairs who had not referred each other to the clinic and may have been missing network intermediaries. Three of the fourteen phylogenetic pairs consisted of only acute/recent members, and zero phylogenetic linkages were located within geospatial clusters. AHI detection programs anchored in STI clinic populations and their neighborhoods could facilitate identification of early HIV infection, enabling treatment initiation and transmission prevention efforts during this most infectious period. Future studies of intervention packages and deployment approaches can help inform the optimal design and implementation of AHI-focused strategies for reducing HIV incidence

Distinct clinical and immunological profiles of patients with evidence of SARS-CoV-2 infection in sub-Saharan Africa

Clinical management of COVID-19 in resource-poor settings has distinct challenges and detailed patient characterisation is needed. Here, the authors describe the clinical and immunological profiles of patients at a hospital in Malawi with confirmed and suspected COVID-19

Distinct clinical and immunological profiles of patients with evidence of SARS-CoV-2 infection in sub-Saharan Africa

Although the COVID-19 pandemic has left no country untouched there has been limited research to understand clinical and immunological responses in African populations. Here we characterise patients hospitalised with suspected (PCR-negative/IgG-positive) or confirmed (PCR-positive) COVID-19, and healthy community controls (PCR-negative/IgG-negative). PCR-positive COVID-19 participants were more likely to receive dexamethasone and a beta-lactam antibiotic, and survive to hospital discharge than PCR-negative/IgG-positive and PCR-negative/IgG-negative participants. PCR-negative/IgG-positive participants exhibited a nasal and systemic cytokine signature analogous to PCR-positive COVID-19 participants, predominated by chemokines and neutrophils and distinct from PCR-negative/IgG-negative participants. PCR-negative/IgG-positive participants had increased propensity for Staphylococcus aureus and Streptococcus pneumoniae colonisation. PCR-negative/IgG-positive individuals with high COVID-19 clinical suspicion had inflammatory profiles analogous to PCR-confirmed disease and potentially represent a target population for COVID-19 treatment strategies

Self-Determination in Global Health Practices – Voices from the Global South

Despite the commendable progress made in addressing global health challenges and threats such as child mortality, HIV/AIDS, and Tuberculosis, many global health organizations still exhibit a Global North supremacy attitude, evidenced by their choice of leaders and executors of global health initiatives in low- and middle-income countries (LMICs). While efforts by the Global North to support global health practice in LMICs have led to economic development and advancement in locally led research, current global health practices tend to focus solely on intervention outcomes, often neglecting important systemic factors such as intellectual property ownership, sustainability, diversification of leadership roles, and national capacity development. This has resulted in the implementation of practices and systems informed by high-income countries (HICs) to the detriment of knowledge systems in LMICs, as they are deprived of the opportunity to generate local solutions for local problems. From their unique position as international global health fellows located in different African countries and receiving graduate education from a HIC institution, the authors of this viewpoint article assess how HIC institutions can better support LMICs. The authors propose several strategies for achieving equitable global health practices; 1) allocating funding to improve academic and research infrastructures in LMICs; 2) encouraging effective partnerships and collaborations with Global South scientists who have lived experiences in LMICs; 3) reviewing the trade-related aspects of intellectual property Rights (TRIPS) agreement; and 4) achieving equity in global health funding and education resources

High blood pressure comes from thinking too much: Understandings of illness among couples living with cardiometabolic disorders and HIV in Malawi.

Cardiometabolic disorders (CMD) such as hypertension and diabetes are increasingly prevalent in sub-Saharan Africa, placing people living with HIV at risk for cardiovascular disease and threatening the success of HIV care. Spouses are often the primary caregivers for people living with CMD, and understanding patients and partners conceptions of CMD could inform care. We conducted semi-structured interviews with 25 couples having a partner living with HIV and either hypertension or diabetes. Couples were recruited from HIV clinics in Malawi and were interviewed on beliefs around symptoms, causation, prevention, and treatment for CMD. Data were analyzed at the individual and dyadic levels using framework analysis and Kleinmans theory of explanatory models as a lens. On average, participants were 51 years old and married for 21 years. Approximately 57%, 14%, and 80% had hypertension, diabetes, and HIV. Couples endorsed a combination of biomedical explanatory models (beliefs around physical and mental health) and traditional explanatory models (beliefs around religion and natural remedies), although tended to emphasize the biomedical model. Half of couples believed stress was the main cause of hypertension. For diabetes, diet was believed to be a common cause. In terms of prevention, dietary changes and physical activity were most frequently mentioned. For disease management, medication adherence and diet modifications were emphasized, with some couples also supporting herbal remedies, stress reduction, and faith in God as strategies. Participants were generally more concerned about CMD than HIV due to poor access to CMD medications and beliefs that CMD could lead to sudden death. Within couples, partners often held many of the same beliefs but diverged around which etiological or preventive factors were most important (e.g., stress versus diet) and the best diet for CMD. Health education programs should involve primary partners to build knowledge of CMD and address overlap with HIV, and reinforce accurate information on lifestyle factors for the prevention and treatment of CMD
