Item Features of Covid-19 patients detected during community screening: A study from a rural hospital in Sri Lanka.(The Sri Lanka Medical Association., 2020) Senanayake, A.P.; Indrakantha, D.; Sumathipala, S.; Wanigasuriya, K.; Kularathne, S.; Lekamwasam, S.; Jayasinghe, S.; de Silva, H.J.; Siribaddana, S.ABSTRACT: We studied the clinical course and virus shedding of all patients referred to Welikanda Hospital, in one month. There were 53 positives for Covid-19 by PCR. 24 (45%) were male, with an age range of 11-94 years. Of these, 41 (77%) were asymptomatic, 9 had cough, 4 had sore throat and six had fever. Pulse, blood pressure, respiratory rate and capillary oxygen were normal in all. A proportion of them had poor prognostic factors: asthma (n=4), hypertension (n=11), age above 60 years (n=9), and diabetes (n=11). Lymphopenia was seen in 20 and elevated CRP in 14. Viral shedding continued beyond 14 days in several persons and continued in symptomatic patients for a significantly longer time than asymptomatic patients. Covid-19 was an asymptomatic or mild illness in this group of people. Several of them continued to be RT-PCR positive even after 14 days. Such cases are an important source of community spread.Item Hydroxychloroquine for post-exposure prophylaxis of COVID-19 among naval personnel in Sri Lanka: study protocol for a randomized, controlled trial(BioMed Central, 2020) Niriella, M.A.; Ediriweera, D.S.; de Silva, A.P.; Premaratna, R.; Balasooriya, P.; Duminda, K.D.; Malavige, N.G.; Wanigasuriya, K.; Lekamwasam, S.; Kularathne, S.A.; Siribaddana, S.; de Silva, H.J.; Jayasinghe, S.BACKGROUND: The first case of a coronavirus 2019 (COVID-19) infection in a Sri Lankan was reported on March 11, 2020. The situation in Sri Lanka changed with the rapid increase of personnel contracting COVID-19 in a naval base camp that housed more than 4000 people. This provided a unique opportunity to study the effectiveness of hydroxychloroquine (HCQ) for post-exposure prophylaxis (PEP), while taking stringent, non-pharmacologic, public health measures to prevent spread. Our aim is to study the effectiveness and safety of HCQ for PEP among naval personnel with exposure to COVID-19-positive patients. METHODS/DESIGN: This is a placebo-controlled, randomized, clinical trial carried out in the naval base camp and quarantine centers of the Sri Lanka Navy, Ministry of Defense, Sri Lanka. Navy personnel who are exposed to a patient with confirmed COVID-19 infection but test negative for the virus on reverse real-time polymerase chain reaction (rRT-PCR) at recruitment will be randomized, 200 to each arm, to receive HCQ or placebo and monitored for the development of symptoms or rRT-PCR positivity for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus for 14 days. DISCUSSION: This trial will provide high-quality evidence of the effectiveness and safety of HCQ as PEP for COVID-19. The study design is unique due to the circumstances of the outbreak in a confined area among otherwise healthy adults, at a relatively early stage of its spread.
