Despite the widespread of coronavirus disease-19 (CO­VID-19) infection around the world, there are very scarce reported literature about the care of patients with a known diagnosis of hemoglobin disorders such as sickle cell disease (SCD) or thalassemia and confirmed COVID-19 infection. Thalassemia International Federation issued a position statement to include patients with thalassemia and SCD among the high-risk groups of patients. Here, we present an interesting case of a 42-year-old patient know to have SCD presenting with Vaso-occlusive (VOC) pain episode in the absence of COVID-19 signs and symptoms, who tested positive for COVID-19 infection and had a smooth recovery. This case highlights the importance of screening SCD patients presenting with VOC-related events even in the absence of COVID-19 signs and symptoms.

Sickle cell disease (SCD) is the most common genetic disease in sub-Saharan Africa. The signs and symptoms of SCD usually begin in early childhood. Characteristic features of this disorder include anaemia, repeated infections, and periodic episodes of pain. Malaria is one of the infections that can occur in patients with SCD in endemic countries. Many guidelines recommend antimalarial chemoprophylaxis in these patients, although the debate on which drug should be used is still ongoing. Hydroxyurea (HU), which is considered a safe and effective treatment for both children and adults with SCD, seems to affect the incidence and severity of malaria, although these impacts have yet to be fully demonstrated. We report a case of an eight-and-a-half-year-old Sudanese boy with SCD treated with HU admitted for suspected severe malaria who showed a recrudescence after first-line treatment. Although he had undergone splenectomy and thus belonged to a category of patients at high risk for infectious complications, he was not receiving any malaria chemoprophylaxis. This case emphasises the importance of the routine administration of malaria prophylaxis to children with SCD living in endemic areas, even when they are treated with HU, and especially if they are at high risk for infectious complications because they have undergone splenectomy. There is an urgent need for further research to evaluate the most appropriate regimen and its optimal duration.

Abstract Background: The Stroke Prevention Trial in Sickle Cell Anemia (STOP) and Optimizing Primary Stroke Prevention in Sickle Cell Anemia (STOP 2) established routine transcranial Doppler ultrasound (TCD) screening with indefinite chronic red cell transfusions (CRCT) for children with abnormal TCD as standard of care. To identify children at high-risk of stroke, annual TCD screening is recommended from ages 2 to 16 years, with more frequent monitoring if the result is not normal. A reduction in stroke incidence in children with SCD has been reported in several clinical series and analyses utilizing large hospital databases when comparing rates before and after the publication of the STOP study in 1998. We sought to determine the rate of first ischemic stroke in a multicenter cohort of children who had previously participated in the STOP and/or STOP 2 trials and to determine whether these strokes were screening or treatment failures. Subjects and Methods: Between 1995 and 2005, STOP and STOP 2 (STOP/2) were conducted at 26 sites in the US and Canada. These studies included 3,835 children, ages 2 to 16 y with SCD type SS or S-beta-0-thalassemia. Participation in STOP/2 ranged from a single screening TCD to randomization. STOP 2 also had an observational arm for children on CRCT for abnormal TCD whose TCD had not reverted to normal. The Post-STOP study was designed to follow-up the outcomes of children who participated in one or both trials. 19 of the 26 original study sites participated in Post-STOP, contributing a total of 3,539 (92%) of the STOP/2 subjects. After exit from STOP/2, these children received TCD screening and treatment according to local practices. Data abstractors visited each clinical site and obtained retrospective data from STOP/2 study exit to 2012-2014 (depending on site) including follow-up TCD and brain imaging results, clinical information, and laboratory results. Two vascular neurologists, blinded to STOP/2 status and prior TCD and neuroimaging results, reviewed source records to confirm all ischemic strokes, defined as a symptomatic cerebral infarction; discordant opinions were resolved through discussion. For the first Post-STOP ischemic stroke, prior TCD result and treatment history subsequently were analyzed. Results: Of the 3,539 subjects, follow-up data were available for 2,850 (81%). Twelve children who had a stroke during STOP or STOP2 were excluded from these analyses resulting in data on 2,838 subjects. The mean age at the start of Post-STOP was 10.5 y and mean duration of follow-up after exiting STOP/2 was 9.1 y. A total of 69 first ischemic strokes occurred in the Post-STOP observation period (incidence 0.27 per 100 pt years). The mean age at time of stroke was 14.4±6.2 (median 13.8, range 3.5-28.9) y. Twenty-five of the 69 patients (36%) had documented abnormal TCD (STOP/2 or Post-STOP) prior to the stroke; 15 (60%) were receiving CRCT and 9 (36%) were not (treatment data not available for 1 subject). Among the 44 subjects without documented abnormal TCD, 29 (66%) had not had TCD re-screen in the Post-STOP period prior to the event; 7 of these 29 (24%) were 16 y or older at the start of Post-STOP, which is beyond the recommended screening age. Four of the 44 (9%) patients had inadequate TCD in Post-STOP (1 to 10.7 y prior to event). Six (14%) had normal TCD more than a year before the event (1.2 - 4 y); all but one of these children were younger than 16 y at the time of that TCD. Only 5 (11%) had a documented normal TCD less than 1 year prior to the event. Conclusions: In the Post-STOP era, the rate of first ischemic stroke was substantially lower than that reported in the Cooperative Study of Sickle Cell Disease, prior to implementation of TCD screening. Many (39%) of the Post-STOP ischemic strokes were associated with a failure to re-screen according to current guidelines, while only 11% occurred in children who had had recent low-risk TCD. Among those known to be at high risk prior to stroke, treatment refusal or inadequate treatment may have contributed. While TCD screening and treatment are effective at reducing ischemic stroke in clinical practice, significant gaps in screening and treatment, even at sites experienced in the STOP protocol, remain to be addressed. Closing these gaps should provide yet further reduction of ischemic stroke in SCD. Disclosures No relevant conflicts of interest to declare.

Nigeria leads the world in the number of cases of sickle cell disease (SCD). An estimated 150,000 babies are born annually in Nigeria with SCD, a heredity disorder, and 70-90% die before age 5. Only a small portion of affected infants and children in sub Saharan Africa (SSA) reach adolescence. Over 650 children die per day in sub-Saharan Africa from SCD. These dismal statistics are in sharp contrast to outcomes in high-income countries (HICs) where more than 90% of SCD patients reach adulthood. The World Health Organization (WHO) estimates that 70% of deaths could be prevented with a low cost diagnostic and treatment plan. Meaningful preventive care and treatment cannot be implemented without a structured plan for early diagnosis and patient tracking.Early diagnosis requires improved access to parents and guardians of children with SCD, and gaining this access remains a challenge in most of SSA. In 2015, Nigeria's Kano state government, with support from foreign partners, established a community-based program for newborn registration. This platform provides unique access to newborn babies in one of Nigeria's most populous cities, but still lacks a functioning patient testing, tracking, and monitoring system, which we plan to address in our ongoing study. This study will introduce mobile health in a low-income country with low literacy rate and hopefully accustom that segment of the population to more varied mobile health applications that will ultimately improve their health in the long run. Our current operational platform in Kano, Nigeria provides access to a large population with a high prevalence of SCD. We have previously completed pilot testing of 315 subjects for SCD using our microchip electrophoresis test. We are planning to test up to 4,500 additional subjects less than 5 years of age at Murtala Muhammed Specialist Hospital. The hospital staff includes 97 physicians and 415 nurses and outpatient clinics serve about 30,000 patients monthly. The maternity department has a 200-bed capacity and the antenatal clinic performs about 1,000 deliveries and serves an average of 3,000 mothers monthly. Enrollment is planned to start on September 15, 2019 and medical staff are currently being trained to run the tests. Our study is registered in the United States National Library of Medicine's ClinicalTrials.gov (Identifier: NCT03948516). Our technology is uniquely paired with an automatic reader and an Electronic Medical Record (EMR) and patient management solution to record POC test results, register new cases, and track patients for follow-up (Fig. 1). The reader enables automated interpretation of test results, local and remote test data storage, and includes geolocation (Global Positioning System) (Fig. 2). The system will generate reports for all cases of SCD, track hospital visits, appointments, lab tests, and will have mobile and dashboard applications for tracking patients and samples. The application will be installed on mobile devices provided to users. The proposed system will be compliant with the existing privacy standards to handle medical data (e.g., HIPAA in the US and GDPR in the EU). All communications between the parties will be secured via end-to-end encryption as a safeguard. We anticipate that our project will increase the rates of screening, diagnosis and timely treatment of SCD in Kano State of Nigeria. The project's broader impact will likely be the ability to track and monitor screening, disease detection, diagnosis and treatment, which can be scaled up to the whole nation of Nigeria, then to sub-Saharan Africa. The data obtained and analyzed will be the first of their kind and will be used to inform the design of programs to improve access to, and availability of, effective care for this underserved populations. The importance of increased access to diagnosis and treatment should not be underestimated - it is crucial for realizing effective management of people with SCD. The impact can be enhanced by complementing diagnosis and patient tracking with education for the families so they can provide or seek the necessary preventative treatment. Identification of the location of the patients in need would help identify the areas where family, parent, caregiver education should be provided.

Chronic Intrahepatic Cholestasis

Sickle cell/β+thalassemia (Hb S/β+thal) is considered as a variant form of sickle cell disease. Acute episodes of vasoocclusive pain crisis are characteristic for sickle cell disorders and may be complicated by an acute or chronic life-threatening organ dysfunction. Chronic intrahepatic cholestasis is a rare and severe complication in sickle cell disease, characterized by marked hyperbilirubinemia and acute hepatic failure with an often fatal course. Despite the fact that patients with Hb S/β+thal usually have a mild type of disease, herein we describe an interesting case of chronic intrahepatic cholestasis with successful outcome in an adult patient with Hb S/β+thal.
