It is often accompanied by other autoimmune pathologies. The objective was to study its profile in patients followed in the internal medicine department of the Abass Ndao hospital center. <strong>Methods:</strong> This was a retrospective and descriptive study of patients followed for Biermer’s disease from January 1, 2014 to December 31, 2019 (5 years). <strong>Results:</strong> 57 cases were collected, an incidence of 5.4 in the internal medicine department. The sex ratio was 0.58, an average age of 56.4 years. The circumstances of discovery were dominated by anemic syndrome (87.7%), dermatological (33.3%), digestive (29.8%), neurological (20%) pathologies. The specific signs to Biermer’s disease were digestive manifestations in 70.2% (including 30% Hunter’s glossitis), neurological manifestations in 36.8% (including 17.5% paresthesias), palmoplantar melanoderma in 68.4%. The mean hemoglobin level was 6.8 g/dL with a mean corpuscular volume of 110.7 fl. The myelogram reported megaloblastosis in 100% of the cases. The mean serum vitamin B12 level was 100 pg/ml. The anti-intrinsic factor antibody assay performed in 50 patients was positive in all cases. Upper digestive endoscopy showed an aspect of fundic atrophy in 69%. Histology showed intestinal metaplasia in 2 patients. An autoimmune disease was associated in 21% of cases. All patients had received treatment with vitamin B12 (51 patients took intramuscularly and 6 oral treatment). The course was favorable in all cases with a complete correction of the anemia. <strong>Conclusion:</strong> Biermer’s disease is a reality in Senegal. Its clinical and biological characteristics can be superimposed on the data in the literature. His prognosis under treatment is good whatever the route of administration of vitamin B12.展开更多

It is a rare clinical entity especially in subsahara Africa. Case presentation: We report the case of a 45 years old female patient who consulted for a one month history of generalised muscle cramps, weakness and numbness of all four limbs. Physical examination was relevant for a poor gait, poor coordination of both upper and lower limbs, a positive Romberg sign, normal muscle tone in all four limbs, reduced pallesthesia and deep tendon reflexes, abolished plantar reflexes. Paraclinical investigations revealed macrocytosis without anemia, a low cyanocobalamin (vitamin B<sub>12</sub>) level with a normal folic acid level, an atrophic corporeofundic mucosa which upon pathological analysis revealed a chronic atrophic gastritis with no Helicobacter pylori infection. Anti-intrinsic factor antibodies were positive while anti parietal cells antibodies were negative. The diagnosis of Biermer disease was considered and the patient did well on vitamin B<sub>12</sub> supplementation. Conclusion: Though a rare disease, Biermer disease should be considered in a patient who consults for polyneuropathy even in the absence of anemia.展开更多

These clinical manifestations are polymorphic and severe in our context. The objective of this work is to identify the epidemiological-clinical, therapeutic and evolutionary characteristics of Biermer’s disease in Guinean population. Materials and methods: This was a retrospective of patient files followed for Biermer’s disease at the internal medicine department of Donka National Hospital from January 2012 to December 2021. Results: Eight patients were included including 5 women and 3 men. The average age of the patients was 48 years old. The diagnostic delay was 3.6 years on average. All our patients had bioclinical anemia (8 cases, i.e. 100%) followed by epigastralgia in 4 cases (50%), neurological damage such as sensitive polyneuropathy in 3 cases (37.5%). Four patients had acquired melanoderma (50%). Hypovitaminosis B12 was found in 4 patients. The myelogram performed in three patients (37.5%) found medullary megaloblastosis. One patient had Hashimoto’s disease associated with Biermer’s disease in endoscopy, (FOGD) found fundica trophy on macroscopy in 4 cases (50%). Treatment consisted of B12 vitamin therapy in all cases with a favorable clinical and biological outcome. Conclusion: Biermer’s disease remains common in Africa and is characterized at a younger age in addition to the severity of clinical and biological manifestations. The care consists of taking vitamin B12 which remains accessible in our context.展开更多

The objective was to study their profile at the Medical Clinic II of the Abass Ndao Hospital. Patients and Methods: This was an observational, descriptive and analytical study, lasting 24 months, from January 1, 2020 to December 31, 2022. We assessed the epidemiological, clinical and paraclinical characteristics of the patients and classified the APs found. Results: We included 40 patients divided into type III (38 cases) and IV (2 cases). A female predominance was noted with a sex ratio of 0.21. The mean age was 38.6 years. A family history of component diseases of autoimmune polyendocrine syndrome (APS) was found in 62.5%. Goiter (80%) was the main clinical sign present. All 38 patients with ISAP-3 had autoimmune thyroiditis, including 29 cases of Graves’ disease (72.5%) and 9 cases of Hashimoto’s thyroiditis (22.5%). They were associated with either type 1 diabetes (57.9%), Biermer’s disease (21.1%), vitiligo + alopecia (18.4%), lupus (2.6%). The 2 patients with AP-4 had Biermer’s disease associated with either Addison’s disease or type 1 diabetes. Management depended on the pathologies present and their possible complications. The immunological phenomena were also controlled. Conclusion: This series is globally similar to the literature. The polymorphous character of the clinical pictures requires a better collaboration between specialists leading to a clinical and holistic synthesis.展开更多
