Snakebite envenomation (SBE) is a public health issue in sub-Saharan countries. Antivenom is the only etiological treatment. Excellent tolerance is essential in managing SBE successfully. This study aimed to evaluate tolerance of InoserpTM PAN-AFRICA (IPA). It was conducted on fourteen sites across Cameroon. IPA was administered intravenously and repeated at the same dose every two hours if needed. Early and late tolerance was assessed by the onset of clinical signs within two hours and at a visit two weeks or more after the first IPA administration, respectively. Over 20 months, 447 patients presenting with a snakebite were included. One dose of IPA was administered to 361 patients and repeated at least once in 106 patients. No significant difference was shown between the proportion of adverse events in patients who received IPA (266/361, 73.7%) and those who did not (69/85, 81.2%) (p = 0.95). Adverse reactions, probably attributable to IPA, were identified in four (1.1%) patients, including one severe (angioedema) and three mild. All these reactions resolved favorably. None of the serious adverse events observed in twelve patients were attributed to IPA. No signs of late intolerance were observed in 302 patients. Tolerance appears to be satisfactory. The availability of effective and well-tolerated antivenoms would reduce the duration of treatment and prevent most disabilities and/or deaths.

BACKGROUND
Snakebites is a serious public health issue but remains a neglected tropical disease. Data on antivenom effectiveness are urgently needed in Africa. We assessed effectiveness of Inoserp PAN-AFRICA (IPA), the recommended antivenom available in Cameroon.
METHODOLOGY/PRINCIPAL FINDINGS
We enrolled 447 patients presenting with snakebite in 14 health facilities across Cameroon. At presentation, cytotoxicity, coagulation troubles and neurotoxicity were graded. We administered two to four vials of antivenom to patients based on hemotoxic or neurotoxic signs. We renewed antivenom administration to patients with persistence of bleedings or neurotoxicity 2 hours after each injection. We defined early improvement as a reduction of the grade of envenomation symptoms 2 hours after first injection. Medium-term effectiveness was investigated looking at disappearance of symptoms during hospitalization. After hospital discharge, a home visit was planned to assess long-term outcomes.
Between October 2019 and May 2021, we enrolled 447 (93.7%), including 72% from the savannah regions. The median [IQR] age was 25 [14–40]. Envenomation was diagnosed in 369 (82.6%) participants. The antivenom was administered to 356 patients (96.5%) of whom 256 (71.9%) received one administration. Among these patients, cytotoxic symptoms were observed in 336 (94.4%) participants, coagulation disorders in 234 (65.7%) participants and neurotoxicity in 23 (6.5%) participants. Two hours after the first administration of antivenom, we observed a decrease in coagulation disorders or neurotoxicity in 75.2% and 39.1% of patients, respectively. Complete cessation of bleedings and neurotoxicity occurred in 96% and 93% of patients within 24 hours, respectively. Sequelae have been observed in 9 (3%) patients at the home visit 15 days after hospital admission and 11 (3%) died including one before antivenom injection.
CONCLUSIONS/SIGNIFICANCE
We confirmed good effectiveness of the IPA and highlighted the rapid improvement in bleeding or neurotoxicity after the first administration. Sequential administrations of low doses of antivenom, rigorously assessed at short intervals for an eventual renewal, can preserve patient safety and save antivenom.

Despite the fact that HIV can be controlled with medication to undetectable levels where it cannot be passed on, stigmatization of women living with HIV persists. Such stigmatization pivots on stereotypes around sex and sexism and has force in women’s lives. Our aim was to create an inspirational resource for women living with HIV regarding sex, relationships, and sexuality: www.lifeandlovewithhiv.ca (launched in July 2018). This paper describes the development and mixed-method evaluation of our first year and a half activities. We situated our work within a participatory arts-based knowledge translation planning framework and used multiple data sources (Google Analytics, stories and comments on the website, team reflections over multiple meetings) to report on interim outcomes and impacts. In our first 1.5 years, we recruited and mentored 12 women living with HIV from around the world (Canada, Australia, New Zealand, Kenya, South Africa, Spain, Nigeria, and the U.S.) to write their own stories, with the support of a mentor/editor, as a way of regaining control of HIV narratives and asserting their right to have pleasurable, fulfilling, and safer sexual lives. Writers published 43 stories about pleasure, orgasm, bodies, identities, trauma, resilience, dating, disclosure, self-love, and motherhood. Our social media community grew to 1600, and our website received approximately 300 visits per month, most by women (70%) and people aged 25–44 years (65%), from more than 50 cities globally, with shifts in use and demographics over time. Qualitative data indicated the power of feminist digital storytelling for opportunity, access, validation, and healing, though not without risks. We offer recommendations to others interested in using arts-based digital methods to advance social equity in sexual health.
