Clinical characteristics and risk factors for lupus flares in sub-Saharan Africa-retrospective cross-sectional study.

Systemic lupus erythematosus (SLE) is an autoimmune disease with a variable course with unpredictable flares. Identifying predictors of these flares is essential for monitoring and timely hospital care. To characterize the prevalence of flares within the first five years of SLE diagnosis and determine the clinical and immunological characteristics associated with flare development among patients attending the Rheumatology Clinic at Tikur Anbesa Specialized Hospital (TASH) and Lancet General Hospital. A multicenter, cross-sectional study was conducted from May 2023 to November 2023 at TASH and Lancet General Hospital. The data was collected from electronic medical records and analyzed using SPSS version 26. Logistic regressions were used to determine factors associated with lupus flare. Most patients with SLE were female (95.4%). The most common clinical presentations were musculoskeletal (71.8%), cutaneous (55%), and constitutional (22%). Almost half (44.3%) of the patients had comorbidity illness. Positive ANA test was found in 96.5% of the patients, whereas only 55% had positive anti-dsDNA test. The prevalence of SLE flare in the first five years of SLE diagnosis was 38.9%, and most flares occurred within the first year of diagnosis. Patients with the following characteristics were more likely to have flare-ups: younger age at diagnosis (less than 25 years old), initial presentation with vasculitis, renal flare, and being on low-dose prednisolone. The most common clinical presentations were musculoskeletal, dermatologic, and constitutional manifestations. Age < 25 years at diagnosis, initial clinical presentation with renal manifestation, and being on low-dose prednisolone were predictors of SLE flare. Key Points • This study found a significant gender disparity, with 95% female. • Nearly 39% of patients experienced an SLE flare within the first five years of diagnosis. • Over three-quarters (77%) of flares occurred within the first year of diagnosis. • Age less than 25 years, initial presentation with vasculitis, renal involvement, and being on low-dose prednisolone were identified as predictors of flares.

Unveiling the nephrotoxic profile of BCR-ABL tyrosine kinase inhibitors: A real-world experience in Africa.

Introduction: The efficacy of BCR-ABL tyrosine kinase inhibitors (TKIs) in treating chronic myelogenous leukemia and other malignancies is well-documented. However, concerns about potential nephrotoxicity have raised questions. This study, conducted at Tikur Anbesa Specialized Hospital (TASH) in Addis Ababa, Ethiopia, aimed to investigate the association between TKIs and renal toxicities. Methods: A hospital-based cross-sectional design was used to enroll 260 TASH patients actively receiving BCR-ABL TKIs. Demographic information, diagnoses, treatment details, and laboratory test results were collected for each participant's Electronic Medical Record. The primary goal was to assess adverse renal events, a combination of events of a decrease in estimated glomerular filtration rate (eGFR) exceeding 30% from baseline, significant proteinuria, and a diagnosis of acute kidney injury (AKI) or chronic kidney disease (CKD). A logistic regression model was used to analyze the data and identify factors associated with developing adverse renal events. Results: Our analysis revealed a statistically significant decrease in eGFR following treatment with TKIs. However, the observed rate of adverse renal events (13.1%) was lower than reported in some previous studies. Factors significantly associated with adverse renal events included longer TKI duration, male sex (protective), hypertension, HIV infection, and achieving complete molecular remission and/or a complete hematologic response. No significant associations were found with diabetes mellitus, age, angiotensin-converting enzyme inhibitors use, or baseline creatinine level. Conclusions: While this study found that BCR-ABL TKIs can lead to a decline in eGFR, AKI, and CKD, it also demonstrated that they were relatively safer in our study population.

The Role of Extracorporeal Photopheresis in the Management of Graft Versus Host Disease: Narrative Review.

Hematopoietic stem cell donation is a method used to treat both blood-related and non-blood-related malignancies. Graft-versus-host disease is a potentially life-threatening complication that can occur following a stem cell transplant from a donor. This happens after the transplanted grafts attack the recipient's body as foreign cells, causing significant morbidity and mortality. Clinically, this condition can be classified as acute or chronic based on onset and pathophysiology. This review aims to provide an overview of recent studies on extracorporeal photopheresis as a treatment strategy option for graft-versus-host-diseased patients. It will explain how it treats graft-versus-host disease, summarize its promising effects, and provide future recommendations for its use in treating this illness. Extracorporeal photopheresis is used to treat graft-versus-host disease by collecting and separating white blood cells from the patient. This blood is fractionated into different parts, and white blood cells undergo treatment with 8-methoxy psoralen, a photoactivable drug, before exposure to ultraviolet light A. Lastly, the cells that have been treated are reinfused into the recipient's body. It prompts the programmed cell death of lymphocytes and the engulfment of cellular debris by host antigen-presenting, leading to a subsequent rise in T regulatory cells. However, more experimental and randomized controlled studies are required to identify the best patient selection requirements, environments, and treatment regimens for graft-versus-host disease.

Uptake of Immediate Postpartum LARCs and Associated Factors among Mothers Who Gave Birth at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia.

Background: Postpartum family planning is an effective strategy for reducing maternal and childhood morbidity and mortality by preventing unintended pregnancy and short interpregnancy intervals. Despite the paramount advantages of long-acting reversible contraceptives (LARC), their uptake remains low in Ethiopia. Therefore, the aim of this study was to assess the uptake of immediate postpartum LARC methods and its associated factors among women who gave birth in Hawassa University Comprehensive Specialized Hospital, Hawassa city, Southern Ethiopia. Methods: An institution-based cross-sectional study was conducted among 418 eligible mothers who were in the immediate postpartum period. Data were collected using a pretested structured questionnaire before their discharge from the hospital and analyzed by using SPSS version 20. The statistical significance was declared at P value less than 0.05. Results: The uptake LARCs among immediate postpartum mothers was 25.4%. The most commonly reported reasons for not using LARC were preference to start contraception after six weeks of delivery (43.3%) and the need to use other methods of contraception (26%). Having unplanned birth (AOR: 1.97; 95% CI: 1.04-3.71) and receiving family planning counselling on LARCs during the postpartum period (AOR: 21.1; 95% CI: 6.49-68.66) were factors significantly associated with immediate postpartum LARC use. Conclusion: Low utilization of immediate postpartum LARC uptake was found in the current study setting. There was increased utilization of immediate postpartum LARC among mothers who received family planning counselling during the postpartum period. Therefore, strengthening family planning counselling during the immediate postpartum period is crucial to enhance postpartum LARC use.
