Varicella zoster virus and cytomegalovirus coinfection in a live related kidney transplant recipient: A case report.

Key Clinical Message: The immunomodulatory effect of CMV makes coinfection with other microbes, like VZV possible and potentially deadlier in the post kidney transplant period. Treatment should be started promptly. Both infections can be treated with Valganciclovir. Abstract: Infections are common complications in kidney transplant recipients owing to the lifelong immunosuppression. Cytomegalovirus (CMV) and Varicella Zoster Virus (VZV) infections are quite common in the posttransplant period. Coinfection with both however has been reported only once. The immunomodulatory effect of CMV makes their interaction with other organisms like VZV potentially sinister. This is a case of a young woman who developed coinfection with HZV and CMV in the first month following a live related kidney transplantation from her mother. Transplant surgery went well with good urine output, but serum creatinine did not fall below 1.7 mg/dL. Immunosuppression consisted of intravenous (IV), followed by oral prednisolone, Mycophenolate Sodium (MPS) and Tacrolimus. 25 days after an uneventful surgery, she developed fever, followed by pain and vesicular eruption on the forehead, typical of VZV infection, along with rising creatinine. CMV PCR yielded 300 copies/mL of DNA, which was undetectable in both donor and recipient pre-transplant. Total white blood cell count fell to 2 × 109/L. MPS was temporarily stopped. Treatment with Valgancyclovir led to resolution of fever, skin lesions and brought serum creatinine down to baseline over 2 weeks.

Proximal tubular dysfunction as a predictor of AKI in Hospitalized COVID-19 patients.

BACKGROUND: High concentration of Angiotensin converting enzyme receptors in the proximal tubules make kidneys an early target in COVID-19. Proximal tubular dysfunction (PTD) may act as an early predictor of acute kidney injury (AKI) and more severe disease. METHODS: This prospective observational study was conducted in the COVID unit, Bangabandhu Sheikh Mujib Medical University. 87 COVID-19 patients without known kidney disease were screened for 6 markers of PTD on admission-hyperuricosuria, normoglycemic glycosuria, proteinuria, renal phosphate leak, sodium leak and potassium leak. Positivity of 2 of the first 4 markers was considered as PTD. 35 patients with PTD and 35 without PTD were followed up throughout their hospital stay. RESULTS: 52.9% had PTD on admission. The most prevalent markers were renal sodium leak (67%), followed by proteinuria (66.7%), hyperuricosuria (42.5%), potassium leak (32.2%), phosphate leak (28.7%) and normoglycemic glycosuria (20.7%). Mean age was 55.7 years. 32.9% patients developed AKI. PTD group had higher odds of developing AKI (odds ratio 17.5 for stage 1, 24.8 for stage 2 and 25.5 for stage 3; p<0.0001). The mean duration of hospital stay was 9 days higher in the PTD group (p<0.001). PTD group also had higher odds of transferring to ICU (OR = 9.4, p = 0.002), need for mechanical ventilation (OR = 10.1, p = 0.002) and death (OR = 10.3, p = 0.001). 32.6% had complete PTD recovery during follow-up. CONCLUSION: Proximal tubular dysfunction is highly prevalent in COVID-19 patients very early in the disease and may act as a predictor of AKI, ICU transfer, need for mechanical ventilation and death.

Quality of Life of Patients With Inflammatory Bowel Disease in Bangladesh.

Introduction The importance of maintaining quality of life in managing inflammatory bowel disease (IBD) has increased in recent years. However, there is a lack of studies examining the health-related quality of life (HRQoL) of IBD patients in Bangladesh. Methodology This cross-sectional study was carried out in the IBD clinic, Bangabandhu Sheikh Mujib Medical University (BSMMU) from 2020 to 2022. Data were collected from both ulcerative colitis (UC) and Crohn's disease (CD) patients. HRQoL was recorded on the EuroQol 5 Dimension 5 Level (EQ-5D-5L) questionnaire. Statistical analysis was done by Statistical Analysis Software (SAS, SAS Institute, Cary, NC). Results The mean age was 36.3 years. The majority of the patients were male and had low incomes. People with more monthly income, more frequent relapse, extraintestinal involvement, and moderate to severe disease had lower utility index (p = 0.01, 0.01, 0.0004, and <0.0001, respectively). Among the five individual components, only usual activity was lower in UC patients (p = 0.03); all the other components and consequently the overall utility index did not vary between UC and CD. The visual analog scale (VAS) score seemed to be comparable in UC and CD patients. Conclusion In more severe and frequently relapsing cases of IBD, the utility index representing HRQoL was found to be lower. Comparatively, the HRQoL was mostly similar between patients with UC and CD. Additionally, the mean utility score in IBD patients was higher than that observed in patients with type 2 diabetes mellitus in Bangladesh.

A Case Report of Moyamoya Disease Presenting as Recurrent Right-Sided Weakness.

Moyamoya disease is a cerebrovascular condition characterized by progressive occlusion of the cerebral vessels, particularly in the circle of Willis. This report describes the case of a 12-year-old boy presenting with a history of recurrent right-sided weakness over a period of seven years. Magnetic resonance imaging revealed evidence of both old and recent infarcts, as well as encephalomalacic changes. The diagnosis was confirmed by magnetic resonance angiography, which demonstrated severe stenosis in both internal carotid arteries and the presence of significant collateral formation. In Bangladesh, surgical revascularization for Moyamoya disease had not been previously attempted, and due to financial constraints, the patient's family opted for conservative management with anti-platelet therapy and regular follow-ups. Although a hereditary component is often presumed in Moyamoya disease, no such familial history was identified in this case. Additionally, no associations with immunological, infectious, hematological, vascular, or congenital syndromes were found. Mortality rates for Moyamoya disease are approximately 10% in adults and 4.3% in children, with a significant proportion of affected individuals experiencing cognitive decline. However, the patient in this case maintained intact cognitive function, and with diligent follow-up and anticoagulation therapy, it was anticipated that his functional capacity would remain stable.
