Hepatic micro-abscesses as an unusual initial presentation of systemic lupus erythematosus: A case report.

Key Clinical Message: Hepatic micro-abscesses can be a rare initial presentation of systemic lupus erythematosus (SLE). This case highlights the importance of considering autoimmune etiologies when infectious causes are ruled out and emphasizes the need for early recognition and appropriate treatment of atypical hepatic manifestations in SLE to achieve favorable outcomes. Abstract: Systemic lupus erythematosus (SLE) is an autoimmune disease that affects multiple organs, including the liver. While hepatic involvement in SLE is typically subclinical or associated with mild liver enzyme elevations, rare manifestations such as hepatic micro-abscesses and hepatic vasculitis have been reported. We report the case of a 27-year-old female who presented with persistent high-grade fever, bilateral exudative lymphocytic pleural effusion, hepatic micro-abscesses, anemia, and lymphopenia. Despite extensive investigations and antibiotic therapy, the patient's condition continued to worsen. The diagnosis of hepatic vasculitis, a rare manifestation of SLE, was ultimately made based on clinical suspicion, positive autoimmune markers, and negative septic workup. The patient responded well to high-dose corticosteroid therapy and intravenous immunoglobulin, with resolution of liver lesions and clinical improvement. Hepatic involvement in SLE is diverse, and atypical presentations can pose diagnostic challenges. Hepatic vasculitis, although rare, should be considered in SLE patients presenting with liver lesions. The management involves immunosuppressive therapy, and prompt diagnosis is crucial to prevent further vascular damage. Hepatic micro-abscesses, another rare manifestation of SLE, are thought to result from immune complex deposition. The exact pathogenesis remains unclear. Hepatic micro-abscesses can have both infectious and non-infectious causes, and it is very important to rule out common microbial pathogens. Treatment focuses on managing the underlying SLE activity with immunosuppressive agents. This case highlights the diagnostic challenges and management considerations in atypical hepatic manifestations of SLE. Awareness of rare presentations and collaboration among multiple specialties are essential for accurate diagnosis and appropriate treatment.

Thyroid Storm-Induced Refractory Multiorgan Failure Managed by Veno-Arterial Extracorporeal Membrane Oxygenation Support: A Case-Series.

BACKGROUND Severe hyperthyroidism, including thyroid storm, can be precipitated by acute events, such as surgery, trauma, infection, medications, parturition, and noncompliance or stoppage of antithyroid drugs. Thyroid storm is one of the serious endocrinal emergencies that prompts early diagnosis and treatment. Early occurrence of multiorgan failure is an ominous sign that requires aggressive treatment, including the initiation of extracorporeal membrane oxygenation (ECMO) support as a bridge to stability and definitive surgical treatment. Most adverse events occur after failure of medical therapy. CASE REPORT We described 4 cases of fulminating thyroid storm that were complicated with multiple organ failure and cardiac arrest. The patients, 3 female and 1 male, were between 39 and 46 years old. All patients underwent ECMO support, with planned thyroidectomy. Three survived to discharge and 1 died after prolonged cardiac arrest and sepsis. All patients underwent peripheral, percutaneous, intensivist-led cannulation for VA-ECMO with no complications. CONCLUSIONS Early recognition of thyroid storm, identification of the cause, and proper treatment and support in the intensive care unit is essential. Patients with thyroid storm and cardiovascular collapse, who failed to improve with conventional supportive measures, had the worst prognosis, and ECMO support should be considered as a bridge until the effective therapy takes effect. Our case series showed that, in patients with life-threatening thyroid storm, VA-ECMO can be used as bridge to stabilization, definitive surgical intervention, and postoperative endocrine management. Interprofessional team management is essential, and early implantation of VA-ECMO is likely beneficial in patients with thyroid storm after failure of conventional management.

Prevalence of neutropenia among adult Arabs in Qatar: Relation to other hematological parameters and anthropometric data.

Neutropenia ranges from a normal variant to life-threatening acquired and congenital disorders. This study aims at providing baseline information regarding the prevalence and spectrum of neutropenia in the Arab blood donors who are living in Qatar. This retrospective cohort study was conducted to review the data of healthy Arab individuals (≥18 years) who donated blood between January 1, 2015 to May 15, 2019. A complete blood count was performed using automated analyzers. The prevalence of neutropenia was 10.7%. The prevalence in females was 32% and in males, it was 6%. Absolute neutrophil count (ANC) below 1 × 109/L was detected in 10% of Arab females and 1.8 % of Arab males. In females, the neutropenic group had significantly lower hemoglobin (Hb) levels and higher red cell distribution width, and lower total white blood cells and lymphocyte counts (P < .001) compared to the group with ANC > 1.5 × 109/L. Significant correlations were found between the ANC and Hb (r = 0.33, P < .05) and ANC and total white blood cells (r = 0.45, P < .01). The prevalence of neutropenia is considerably high in Arab adult females compared to other ethnic groups. Besides the genetic constitution of Arabs, the lower Hb and higher red cell distribution width in females suggest that iron deficiency could contribute to the development of neutropenia.

Hematological indices reference intervals for a healthy Arab population in Qatar: Effect of age, gender, and geographic location.

ABSTRACT: Hematologic reference intervals vary with gender, age, ethnicity, and geographic area. Therefore, local or national laboratory reference ranges are essential to enhance the accuracy when diagnosing health conditions. Still, no comprehensive list of reference ranges tailored to the Arab population living in Qatar. Accordingly, this study aims at establishing a hematology reference guide for Arabs in Qatar.This is a retrospective study where 750 healthy volunteers (18-69 years) from 2015 to 2019 were included, analyzed by an automated hematology analyzer. Arab adults were divided into African (Egypt, Libya, Tunisia, Morocco) and Asian (Syria, Lebanon, Jordon, Palestine, Qatar). The Cell-Dyn and Sysmex were used for measuring hematological parameters.The mean +/- 2SD were established for all the study groups. Arab males had significantly higher Hb, Hct, red cell distribution width, absolute neutrophil count, lymphocytes, and monocyte counts than females. Asian-Arab males had significantly higher Hb concentration and higher WBC, lymphocytes, and eosinophils than African Arabs. Asian-Arab young (>18: < 40 years) males had significantly higher Hb and lymphocytes and lower monocytes than older males (>40 years). African-Arab young males had significantly higher lymphocytes and lower monocytes than older males. Asian-Arab young females had higher WBC and absolute neutrophil count than older Asian Arabs.The findings of this study will help in establishing specific reference intervals in the Arab world. The differences in hematology reference intervals considering age, gender, and geographical location highlight the importance of establishing blood reference intervals in each country considering the ethnic diversity of each country.
