Prevalence and prognosis of fulminant type 1 diabetes mellitus in The Middle East: a comparative analysis in a 5-year nationwide cohort.

PURPOSE: To analyze the prevalence and progression of fulminant type 1 diabetes (FT1D) in Qatar. METHODS: This retrospective study analyzed consecutive index- diabetic ketoacidosis (DKA) admissions (2015-2020) among patients with new-onset T1D (NT1D) in Qatar. RESULTS: Of the 242 patients, 2.5% fulfilled the FT1D diagnostic criteria. FT1D patients were younger (median-age 4-years vs.15-years in classic-T1D). Gender distribution in FT1D was equal, whereas the classic-T1D group showed a female predominance at 57.6% (n = 136). FT1D patients had a mean C-peptide of 0.11 ± 0.09 ng/ml, compared to 0.53 ± 0.45 ng/ml in classic-T1D. FT1D patients had a median length of stay (LOS) of 1 day (1-2.2) and a DKA duration of 11.25 h (11-15). The median (length of stay) LOS and DKA duration in classic-T1D patients were 2.5 days (1-3.9) and 15.4 h (11-23), respectively. The FT1D subset primarily consisted of moderate (83.3%) and severe 916.7%) DKA, whereas classic T1D had 25.4% mild, 60.6% moderate, and 14% severe DKA cases. FT1D was associated with a higher median white cell count (22.3 × 103/uL) at admission compared to classic T1D (10.6 × 103/uL). ICU admission was needed for 66.6% of FT1D patients, compared to 38.1% of classic-T1D patients. None of the patients in the FT1D group had mortality, while two died in the classic-T1D group. CONCLUSION: This is the first study establishing the existence of FT1D in ME, which presented distinctively from classic-T1D, exhibiting earlier age onset and higher critical care requirements. However, the clinical outcomes in patients with FT1D seem similar to classic T1D.

Differential evolution of diabetic ketoacidosis in adults with pre-existent versus newly diagnosed type 1 and type 2 diabetes mellitus.

BACKGROUND: Diabetic ketoacidosis (DKA) was once known to be specific to type-1 diabetes-mellitus (T1D); however, many cases are now seen in patients with type-2 diabetes-mellitus (T2D). Little is known about how this etiology shift affects DKA's outcomes. METHODS: We studied consecutive index DKA admissions from January 2015 to March 2021. Descriptive analyses were performed based on pre-existing T1D and T2D (PT1D and PT2D, respectively) and newly diagnosed T1D and T2D (NT1D and NT2D, respectively). RESULTS: Of the 922 patients, 480 (52%) had T1D, of which 69% had PT1D and 31% NT1D, whereas 442 (48%) had T2D, of which 60% had PT2D and 40% NT2D. The mean age was highest in PT2D (47.6 ± 13.1 years) and lowest in PT1D (27.3 ± 0.5 years) (P < 0.001). Patients in all groups were predominantly male except in the PT1D group (55% females) (P < 0.001). Most patients were Arabic (76% in PT1D, 51.4% in NT1D, 46.6% in PT2D) except for NT2D, which mainly comprised Asians (53%) (P < 0.001). Patients with NT2D had the longest hospital length of stay (LOS) (6.8 ± 11.3 days) (P < 0.001), longest DKA duration (26.6 ± 21.1 h) (P < 0.001), and more intensive-care unit (ICU) admissions (31.2%) (P < 0.001). Patients with PT1D had the shortest LOS (2.5 ± 3.5 days) (P < 0.001), DKA duration (18.9 ± 4.2 h) (P < 0.001), and lowest ICU admissions (16.6%) (P < 0.001). CONCLUSIONS/INTERPRETATION: We presented the largest regional data on differences in DKA based on the type and duration of diabetes- mellitus (DM), showing that T2D is becoming an increasing cause of DKA, with worse clinical outcomes (especially newly diagnosed T2D) compared to T1D.

Post-COVID-19-associated multiorgan complications or "long COVID" with literature review and management strategy discussion: A meta-analysis.

Objective: To investigate the post-COVID-19 long-term complications or long COVID of various organ systems in patients after 3 months of the infection, specifically before the Omicron variant, with comparative literature analysis. Methods: A systemic literature search and meta-analysis were conducted using multiple electronic databases (PubMed, Scopus, Cochrane library) with predefined search terms to identify eligible articles. Eligible studies reported long-term complications of COVID-19 infection before the Omicron variant infection. Case reports, case series, observational studies with cross-sectional or prospective research design, case-control studies, and experimental studies that reported post-COVID-19 complications were included. The complications reported after 3 months after the recovery from COVID-19 infection were included in the study. Results: The total number of studies available for analysis was 34. The effect size (ES) for neurological complications was 29% with 95% confidence interval (CI): 19%-39%. ES for psychiatric complications was 24% with 95% CI: 7%-41%. ES was 9% for cardiac outcomes, with a 95% CI of 1%-18%. ES was 22%, 95% CI: 5%-39% for the gastrointestinal outcome. ES for musculoskeletal symptoms was 18% with 95% CI: 9%-28%. ES for pulmonary complications was 28% with 95% CI: 18%-37%. ES for dermatological complications was 25%, with a 95% CI of 23%-26%. ES for endocrine outcomes was 8%, with a 95% CI of 8%-9%. ES size for renal outcomes was 3% with a 95% CI of 1%-7%. At the same time, other miscellaneous uncategorized outcomes had ES of 39% with 95% CI of 21%-57%. Apart from analyzing COVID-19 systemic complications outcomes, the ES for hospitalization and intensive care unit admissions were found to be 4%, 95% CI: 0%-7%, and 11% with 95% CI: 8%-14%. Conclusion: By acquiring the data and statistically analyzing the post-COVID-19 complications during the prevalence of most virulent strains, this study has generated a different way of understanding COVID-19 and its complications for better community health.

A retrospective study on comparison of clinical characteristics and outcomes of diabetic ketoacidosis patients with and without acute pancreatitis.

The co-existence of diabetic ketoacidosis (DKA) with acute pancreatitis (AP) is associated with unfavorable clinical outcomes. However, diagnosing AP in DKA patients is challenging and often missed due to overlapping symptoms. The aim of this retrospective observational study was to compare the clinical characteristics and outcomes of patients with concomitant DKA and AP or DKA alone. Data of patients with DKA admitted between January 2015 to August 2021 to four hospitals in Qatar was extracted from the electronic health record (Cerner). American Diabetes Association criteria and Atlanta criteria were used for DKA and AP diagnosis, respectively. Independent T-test or Mann-Whitney U test was used to analyze continuous variables, whereas categorical variables were analyzed via Chi-square or Fischer exact tests as appropriate. Univariate and multivariate logistic regression models were generated to assess the correlations. A p-value of < 0.05 was considered statistically significant. Of 936 patients with DKA, 84 (9.0%) had coexisting AP. AP was most common in the Asian race (66%, p < 0.001). Patients with DKA and AP were older, had higher admission anion-gap, white cell count, hemoglobin (hb), neutrophil/lymphocyte ratio, urea, creatinine, maximum blood glucose during the episode, total cholesterol and triglyceride level (TGL) (p < 0.05). They had a lower admission venous pH and bicarbonate at 6 h. Patients in the DKA with AP group also had a longer length of stay (LOS), DKA duration and a higher rate of ICU admission (p-values ≤ 0.001). In-hospital mortality, 3-month all-cause readmission, 6-month and 12-month DKA recurrence did not differ between the two groups. Univariate logistic regression analysis showed age, Asian ethnicity, male gender, T2D, admission WBC count, hb, urea, creatinine, potassium, venous pH, bicarbonate, anion gap, total cholesterol, TGL and LDL level were significantly associated with the development of DKA with AP (p < 0.05). In multivariate logistic regression analysis, age and total cholesterol level were associated with concomitant DKA and AP (p < 0.05). Patients with concomitant DKA and AP have more severe derangement in markers of DKA severity, inflammation, kidney injury and metabolic profile, along with a longer DKA duration, LOS and requirement for ICU support compared to DKA patients without AP. This highlights the clinical significance of diagnosing the co-existence of DKA with AP, as the combination results in significantly worse clinical outcomes and greater healthcare utilization than in patients with only DKA.

Humoral Response of Patients With Autoimmune Rheumatic Disease to BNT162b2 Vaccine: A Retrospective Comparative Study.

Objective The effectiveness and safety of SARS-CoV-2 vaccines in patients with autoimmune rheumatic diseases (ARDs) treated with immunomodulators remain uncertain. Therefore, this study aimed to evaluate whether the humoral immune response to the BNT162b2 vaccine differs between patients without and with ARDs treated with immunomodulators. Methods We retrospectively reviewed 3208 electronic medical records from the database of the Hamad Medical Corporation (HMC) outpatient rheumatology clinics to capture patients with ARDs and control patients without autoimmune inflammatory diseases. All patients who were SARS-CoV-2 infection-naïve, had received two doses of BNT162b2 vaccination, and had been serologically tested using Elecsys® anti-SARS-CoV-2 S immunoassays (Roche Holdings AG, Basel, Switzerland), were included in the analysis. Patients with ARD were classified into six subgroups according to the received ARD immunomodulators: methotrexate monotherapy (MTXM), a combination of conventional synthetic disease-modifying antirheumatic drugs (Cs-DMARDs), tumor necrosis factor inhibitor (TNF-i), rituximab, interleukin-6 inhibitor (IL6-i), and Janus kinase inhibitor (JAK-i). Samples with an anti-SARS-CoV-2 S titer of <0.8 and <132 binding antibody unit (BAU)/mL were defined as negative and poor seroconversion, respectively. The overall mean of anti-SARS-CoV-2 S titer and its level at <0.8 and <132 were compared between the six subgroups of patients with ARD and the controls by performing an unpaired t-test and Chi-squared or Fisher's exact test as appropriate. Results The mean (SD) age of 110 patients with ARDs and 20 controls was 47.1 (12) and 59.3 (8.9) years (P < 0.001), respectively, and women predominated both groups (60% vs. 75%, P = 0.20). The most frequently prescribed Cs-DMARDs was methotrexate in 50 (45.5%) patients, followed by TNF-i in 46 (41.8%), rituximab in 20 (18.2%), JAK-i in 12 (10.9%), and IL6-i in 7 (6.4%) patients. The mean (SD) anti-SARS-CoV-2 S antibody titer of only the rituximab subgroup significantly differed from the controls (P = 0.012). Conclusion The most prevalent ARD immunomodulators (Cs-DMARDs, TNF-i, JAK-i, and IL6-i) were associated with comparable seroconversion rates to the BNT162b2 vaccine. In comparison, rituximab was significantly associated with decreased immunogenicity.

Risk Factors, Clinical Presentation, Diagnosis, and Treatment Outcomes of Portal Vein Thrombosis: A Five-Year Hospital-Based Study From Qatar.

Background: There is a lack of robust epidemiological information on portal vein thrombosis (PVT) in Qatar. This study aimed to describe the risk factors, clinical presentation, diagnosis, and treatment outcomes of PVT in patients with and without liver cirrhosis admitted to Hamad General Hospital. Methods: This retrospective observational study was conducted at Hamad General Hospital, Doha, Qatar. Consecutive patients with PVT between January 1, 2015 and December 31, 2019 were included in this study. Results: We included 363 cases representing 0.05% of all inpatients admitted to our hospital during the study period. Their mean age was 47.79 ± 14.48 years. There were 258 (71.1%) males and 105 (28.9%) females. Abdominal pain was the most common presenting symptom (160 (44.1%)), while splenomegaly was the most common presenting sign (158 (43.5%)). Liver cirrhosis was the most frequent risk factor for PVT (147 (40.5%)), while no risk factors were identified in 49 (13.5%) patients. Anticoagulant therapy was given to 171/207 (82.6%) patients with acute PVT and 19/156 (12.2%) patients with chronic PVT. The options used for anticoagulation treatment were: low molecular weight heparin (LMWH) or unfractionated heparin alone, LMWH/unfractionated heparin followed by warfarin, and direct-acting oral anticoagulants (rivaroxaban). Out of the 262 patients in whom PVT recanalization was assessed, 43.8% of the cases had recanalization after anticoagulation treatment, while 12.6% of them had spontaneous recanalization without such therapy. A comparison between different anticoagulants used in this study showed no significant difference in the effectiveness of the three regimens used. The 30-day mortality was recorded for 71 patients (19.5%). The major risk factors for 30-day mortality were: age over 45 years, male sex, hepatic failure, malignancies, and bilirubin > 34 µmol/L. Conclusion: PVT is a rare clinical entity in Qatar with liver cirrhosis being the most common risk factor. Early administration of anticoagulation therapy is associated with a significant recanalization, while age > 45 years, male sex, hepatic failure, malignancies, and bilirubin > 34 µmol/L are independent risk factors for 30-day mortality.

The demographics of Tolosa-Hunt syndrome in Qatar.

BACKGROUND: Tolosa Hunt syndrome (THS) is a rare disease that manifests mainly as painful unilateral ophthalmoplegia. It is caused by an inflammatory process of unknown aetiology within the cavernous sinus with a rare intracranial extension. The International Classification of Headache Disorders (ICHD)- 3 diagnostic criteria aids in its diagnosis. There is limited literature on its varied presentations, diagnosis, and management. Steroids are used in the treatment of THS with varied success. METHODS: We conducted a single-center-retrospective-study and included all patients admitted with a diagnosis of THS from January 2015 to December 2020. Descriptive and summary statistics were used to describe the study cohort's socio-demographic parameters. RESULTS: Among 31 THS patients (predominantly Asians (18) and Arabs (9)), visual disturbance was commonest presenting complaint. Third-nerve paralysis was seen in 70.9% cases. Magnetic-resonance-imaging (MRI) was abnormal in 64.5%. 93.5% patients received steroids, with a response-rate of 70.9% and a recurrence-rate of 9.7%. A previous history of THS and female gender were associated with recurrence (p-value 0.009 and 0.018). Recurrence was seen in 66.7% fully recovered and 33.3% partially recovered cases (p-value 0.04). Among the benign and inflammatory subtypes of THS, the ICHD-3 criteria were applicable in 85% of inflammatory THS. CONCLUSIONS: THS is a rare disease with ethnic variation in presentation and response to treatment. In our cohort female gender and a previous history of THS were associated with recurrence. ICHD-3 diagnostic criteria had a higher validity in our patients compared to prior studies, especially among the inflammatory THS.

Autoimmune hemolytic anemia associated with vitamin B12 deficiency and viral illness in DiGeorge syndrome. Case report and literature review.

Vitamin B12 plays a crucial role in cell maturation and differentiation. Its deficiency can lead to cytopenias and even hemolysis. We suggest regular monitoring and maintenance of Vit B12 levels in DiGeorge syndrome patients to prevent such triggers.

Favism-induced methemoglobinemia in a G6PD deficient male with a subsequent hemolytic cascade, a therapeutic challenge: Case report and review of literature.

The co-occurrence of acute hemolysis and methemoglobinemia secondary to favism in G6PD deficient individuals is rare. Identifying it promptly is of high clinical significance as treating methemoglobinemia (with methylene blue) can worsen hemolysis.

Rare Association of Patent Foramen Ovale and Atrial Septal Aneurysm Leading to Branch Retinal Artery Occlusion in a Young Healthy Man.

Retinal artery occlusion (RAO) occurs in the elderly population above the age of 60 years due to carotid atherosclerosis as a consequence of long-standing hypertension, diabetes mellitus, smoking, and hyperlipidemia. It can also develop due to paradoxical emboli from patent foramen ovale (PFO), which can happen in a relatively younger population. Early diagnosis mandates prompt management; otherwise, it may lead to vision loss. We present a rare case of branch RAO (BRAO) in a healthy young gentleman with concurrent PFO and large atrial septal aneurysm, which has not been reported much in the literature. Our patient presented with sudden left-sided blurriness of vision, which was diagnosed as BRAO on ophthalmoscope examination. Multidisciplinary teams were involved in reaching the underlying etiology of such a presentation in a young, healthy person. Urgent head CT with cerebral angiography and head MRI was unremarkable for any acute insult. The autoimmune screen and thrombophilia workup were unremarkable. After thorough investigations, a small PFO with a large atrial septal aneurysm was found to be correlating with his clinical picture. We aim to highlight the importance of timely diagnosis and further management in such clinical scenarios, where permanent vision loss can compromise someone's quality of life.

A Conundrum of Diagnostic Analogy Between Constrictive Pericarditis and Pericardial Tamponade.

Constrictive pericarditis and cardiac tamponade are two key pathologies of the pericardium. Both increase the intrapericardial pressure and cause adverse effects on the physiological distention and relaxation of the heart's chambers. They share multiple overlapping features and, therefore, can be very challenging to differentiate between the two with regards to clinical presentation and non-invasive imaging techniques. We present a similar case with a diagnostic challenge from the laboratory investigations and non-invasive imaging. We have discussed the pathophysiology with the common and distinguishing features of the two pathologies when there is an ambiguity.

Tuberculous Adenitis with Concurrent Hodgkin Lymphoma: A Case Report.

The concomitant occurrence of tuberculous adenitis and Hodgkin lymphoma is rare, posing a diagnostic dilemma since both have similar symptoms, such as lymphadenopathy, weight loss, fever, and night sweats. We reported such a case in a 15-year-old girl who presented with fever and neck swelling and was found to have lymphadenopathy. A biopsy of the right supraclavicular lymph node showed Reed-Sternberg cells and stained positive for acid-fast bacilli and tuberculosis culture. The patient was diagnosed with tuberculous adenitis with concurrent Hodgkin lymphoma in the same lymph node. She was started on anti-tubercular medications and chemotherapy and showed clinical improvement. This case highlights the need for suspicion in order to identify these two disorders in the same patient, since missing one of them is possible and may lead to fatal complications.
