Vitamin D Levels Among Rheumatoid Arthritis Sudanese Patients: Prevalence and Correlation to Disease Activity - A Bicentric Study.

Purpose: To evaluate vitamin D levels among adult Sudanese RA patients and identify its correlation with RA disease activity. Patients and Methods: A bicentric cross-sectional analytical hospital-based study was performed in two Khartoum State Hospitals between October 2019 and January 2020, enrolling 90 Sudanese patients with RA. Serum vitamin D levels were measured with a standard reference level of 30ng/mL-100ng/mL. A detailed interview-based questionnaire was used to collect the patient's information, clinical data and lab results-disease activity was assessed via the DAS-28 score. The data was then analyzed using SPSS v-24. Results: Vitamin D levels were low in 79 candidates (87.8%), 53 of which (67.1%) showed moderate insufficiency (10-30ng/mL), and 26 candidates (32.9%) had severe deficiency (less than 10 ng/mL). Regarding the disease activity, 57 participants (63.3%) had moderate disease activity (DAS-28=3.2-5.1), and 22 participants (24.4%) had high disease activity (DAS-28 >5.1). A significant negative correlation was reported between high DAS-28 scores and low vitamin D levels with p-value = <0.001 (95% CI: -0.8591 to 0.0015) and r = -0.44. Conclusion: Most adult Sudanese rheumatoid arthritis patients showed low vitamin D levels (87.8%), which was also significantly correlated with increased disease activity (P-value <0.05). Moreover, the prevalence of low vitamin D levels was significantly higher than in numerous countries worldwide.

Anti-Ribosomal-P Antibody Association with Neuropsychiatric Lupus in Sudanese Patients Attending Rheumatology Clinic in Omdurman Military Hospital.

Purpose: To assess and establish the relationship between neuropsychiatric systemic lupus erythematosus (NPSLE) involvement and serological biomarkers like antiribosomal-P antibodies. Patients and Methods: This is an analytical cross-sectional hospital-based study conducted on patients attending Omdurman Military Hospital from July 2019 to December 2019. A total of 90 patients were enrolled, 30 of whom had NPSLE compared with 60 SLE patients without NPSLE. SLE diagnosis was established based on the revised SLICC criteria (presence of at least 4 criteria) for SLE classification, with neuropsychiatric manifestations defined based on the ACR nomenclature. The immunological examination results have been performed by (ELISA immune-enzymatic method, immunofluorescence, and Western immunoblotting test). SPSS v 21.0 software was utilised for data analysis. Results: NPSLE patients exhibited +ve ANA in 96.7% vs 75% in non-NPSLE (P-value = 0.008), antiribosomal-P antibodies (46.7% vs 20%; P-value = 0.0001), anti-nucleosome antibodies (26.7% vs 5%; P-value = 0.005), and anti-histones antibodies (40% vs 20%; P-value = 0.04). ANA antibodies were significantly associated with neurological manifestations as ANA antibodies were common in epilepsy (n = 9; 91%) and stroke (n = 8; 27.6%) (P-value < 0.001). Conclusion: Neuropsychiatric manifestation of systemic lupus erythematosus exhibits variable clinical manifestations. Neuropsychiatric manifestations of SLE are strongly associated with the anti-ribosomal P antibody presence and can be employed as a powerful diagnostic tool.

Prevalence and risk factors of functional seizures among adult Sudanese patients with epilepsy, a cross-sectional clinic-based study.

Background: Epilepsy can be associated with functional seizures. Our main aim is to assess functional seizures' prevalence and risk factors among adult Sudanese patients with epilepsy. Methods: This cross-sectional clinic-based study was conducted from January to February 2021 at Daoud Charity Clinic in Omdurman city, Sudan. Ninety-nine adult Sudanese patients with epilepsy were included. Data were collected using a validated interview-based semi-structured questionnaire. A senior consultant neurologist and a consultant psychiatrist diagnosed the functional seizures based on full clinical history and investigations. The diagnosis was performed according to International League against epilepsy (ILAE) classification. Results: This study included 99 patients with epilepsy, 57% were females, 79% reside in Khartoum state, and 32% reached secondary school. The main types of epilepsy were generalized tonic-clonic (68%), followed by focal seizures with impaired awareness (11%). The majority of the patients have been diagnosed with epilepsy for over three years (65%). Comorbid epilepsy and functional seizures were found in 29% of the patients, with a significantly higher prevalence in patients with social problems and depression (p = 0.005 and p < 0.01, respectively). Patients with depression had a 14 times higher risk of functional seizures than those without depression, 95% CI [3.8, 52.3]. Conclusion: A remarkably high prevalence of functional seizures was found among adult patients with epilepsy. Patients suffering from social problems and/or depression and poor economic status had a higher tendency to develop functional seizures, especially after two to three years of treatment and above.

Rheumatoid Vasculitis, an Uncommon Complication of Non-Deforming Rheumatoid Arthritis: A Case Report.

We present an 18-year-old female from South Sudan presented with right fingertips ulceration and black discolouration associated with bilateral wrist/metacarpophalangeal joints pain for five months. The ulceration began at the tip of the right middle finger and gradually progressed to involve the rest of the hand and was associated with agonizing pain. A Doppler study of the right upper limb revealed thrombosis of the antecubital portion of the basilar, ulnar, and part of the distal radial arteries. Blood investigations showed high anti-CCP, doubtful rheumatoid factor titre and ANA titre of 1:320 with coarse and nucleated cells; however, all ANA parameters were negative. A definitive diagnosis of rheumatoid arthritis complicated by rheumatoid vasculitis was made. Unfortunately, the middle finger could not be preserved and ended up amputated, and the patient was commenced on steroids, DMARDs and warfarin. The patient responded very well to the management plan with pain alleviation, ulcers healing and clot resolution.

Diabetic myonecrosis, an uncommon presentation of diabetes mellitus in tropical area: A case report.

Diabetic myonecrosis is an uncommon complication related to long-standing poorly controlled diabetes. A 33-year-old Sudanese male patient with type one diabetes presented with progressive, severe bilateral thigh pain with low-grade fever. Laboratory results show hyperglycemia with ketonuria and elevated creatine kinase but normal white cell blood count. The patient was diagnosed initially with diabetic ketoacidosis with pyomyositis and received analgesic and insulin; the patient partially improved. After the second evaluation, bilateral thigh MRI was requested and shows diffuse edema involving the medial muscle group of the upper third of the right side with intramuscular facial edema, appearing as low signal in T1 and high signal in T2 and fat suppression images with no evidence of collection or abscess. Diagnosis of diabetic myonecrosis was made. The patient was managed conservatively and discharge on aspirin with full recovery.

Severe SARS-COV-2 infection in pediatric patient with atypical Hemolytic Uremic Syndrome: A case report.

INTRODUCTION AND IMPORTANT: There is a high incidence of acute kidney injury with COVID-19 infections. We report a child with atypical Hemolytic Uremic Syndrome (aHUS) admitted to Intensive care Unit (ICU) due to severe SARS-COV-2 infection. Children are recognised as at lower risk of severe COVID-19 compared with adults, but the impact of atypical Hemolytic Uremic Syndrome is yet to be determined. CASE PRESENTATION: An eleven years old male presented to Mohammed Alamin Hamid Pediatric Hospital with generalize body swelling, skin rash and red urine. Examination reveal hepatomegaly and hemic murmur. Investigations reveal anemia, normal platelets, and impaired renal function. Peripheral blood picture shows shistocytes, crenated RBCs, occasional poikilocytes and mild neutrophilia.During hospital stay the patient developed severe shortness of breath and fever, diagnosed as COVID-19 and required ICU admission 2 days later due to severe respiratory compromised. CLINICAL DISCUSSION: An atypical Hemolytic Uremic Syndrome with normal platelets is extremely rare condition. SARS-COV-2 infection in patients atypical Hemolytic Uremic Syndrome has not been reported in literature. CONCLUSION: Our study shown that severe SARS-COV-2 infection can be developed in pediatric patients patients with co-existing atypical Hemolytic Uremic Syndrome.
