Despite a sunny environment, we found in this study a high prevalence of hypovitaminosis D (insufficiency + deficiency) in Moroccan men over 50 years old and postmenopausal women.
Background Monoclonal gammopathies are a group of disorders associated with clonal proliferation of plasma cells that produces a monoclonal protein. Aims The main objective of this study was to describe the epidemiological and immunochemical characteristics of monoclonal gammopathies diagnosed during 19 years in a Moroccan teaching hospital. Materials and Results This retrospective study enrolled 443 Moroccan patients with monoclonal gammopathy, patients meeting the inclusion and exclusion criteria in at the biochemistry department of Military Hospital in Rabat, the capital of Morocco, from January 2000 to August 2019. Of the 443 enrolled patients, 320 (72.23%) were men and 123 (27.77%) were women. All patients were of Caucasian origin, from 12 Moroccan regions. The patient's samples were collected and subjected to serum protein electrophoresis and serum immunofixation electrophoresis to further characterize the monoclonal protein. The mean ± SD age of the 443 participants was 62.24 ± 13.14 years. Reasons for being admitted to the hospital were as follows, bone pain (41.60%), renal failure (19.08%), alteration of the general condition (12.21%), and anemia (10.69). Plasma cell proliferative disorders in our study were as follows, multiple myeloma (MM) (45.65%), Monoclonal gammopathies of undetermined significance (MGUS) (39.05%), Waldenstrom's macroglobulinemia (5.58%), Lymphoma (2.27% + 1.2%), Chronic Lymphocytic Leukemia (2.48%), Plasma cell leukemia (1.86%), Plasmacytoma (0.62%), POEMS syndrome (0.41%), and Amyloidosis (0.84%). The most frequent isotypes in MM were the IgGκ (62) 36.5%, IgGλ (52) 30.6%, IgAκ (27) 15.9%, and the IgAλ (19) 11.2%. It is also worth noting that Free light chain MM represents 20% of all cases of MM. Conclusions We found that monoclonal gammopathies are age‐related and affects men more than women, also the results of this study point to the delayed diagnosis of monoclonal gammopathies, since most of our patients were diagnosed at the MM stage. The most frequent isotypes were the IgGκ and IgGλ in MM and MGUS, in Waldenström macroglobulinemia were IgMκ and IgMλ and the oligoclonal profile represented only 3.70%.
Aims The main objective of this work was to evaluate the influence of end-stage renal disease (ESRD) on concentrations of five tumor markers (TMs): carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9 (CA19-9), CA15-3, CA125, and prostate specific antigen (PSA) in a group of chronic hemodialysis patients (CHPs); and to study the influence of hemodialysis (HD) sessions on concentrations of the same TMs. Methods We compared TMs levels in CHP before HD sessions to a control group of 50 healthy volunteers, the dosages were determined before and immediately after the HD session Comparisons were made before and after correction for dialysis-induced hemoconcentrations. Results We enrolled 74 CHPs, all TM concentrations were higher in this group compared to control group, but this increase was significant for CEA (4.25 ± 2.89 vs 2.41 ± 1.81ng/ml; p<0.0001), CA125 (27.84 ± 92.27 vs 13.30 ± 9.85 ng/ml; p = 0.048) and CA19-9 (19.65 ± 25.02 vs 10.23 ± 11.00 U/ml; p = 0.011). Post-dialysis levels were significantly higher than those in pre-dialysis. CEA (3.35 [2,46-5.51] vs 4,06 [2.60-6.78] ng/ml; p<0.0001), CA125 (13.24 [9.66-18.63] vs 16.01 [11.33-22.53] ng/ml; p<0.0001), CA19-9 (12.29 [5.59-21.97] vs 16.29 [7.18-24.7] U/ml; p<0.0001), CA15-3 (13.06 [10.05-17.48] vs 14.58 [11.72-19.35] ng/ml; p<0.0001 and PSA (0.83 [0.5-1.24] vs 1.06 [0.62-1.43] ng/ml; p<0.0001). Conclusions Our work confirms that HD increases concentrations of the five TMs evaluated and suggests that the use of CA15-3 and PSA remains valid in CHPs since their concentrations were not altered by ESRD, unlike CEA, CA125, and CA19-9.
The aim of this study was to describe biological features and aetiology of monoclonal gammopathy diagnosed during a 10-year period in the biochemistry department of the Moroccan Military Hospital Mohamed V in Rabat. The study was performed from 1 January 2000 to 31 December 2009. The records of 261 patients living in the Rabat area in which either serum protein electrophoresis and serum and/or urine immunofixation were performed at the biochemistry department of Military Instruction Hospital in Rabat were analysed. A cohort of 182 (70%) men and 79 (30%) women, the mean ± SD (range) ages were 60.21 ± 12.56 years. All patients were Caucasian. Electrophoresis found that 211 (80.84%) of the patients had a monoclonal gammopathy. Immunofixation confirmed that 251 (96.17%) patients had a monoclonal band in serum. In our cohort, MM was the most frequent diagnosis, our patients were late diagnosed.
BackgroundThe retinopathy is an uncommon complication in individuals with sickle cell trait except for the cases of sickle cell trait associated with systemic arterial hypertension, diabetes mellitus, syphilis, tuberculosis and sarcoidosis.Case PresentationA retinopathy in a 16 year-old child with no history of consanguinity in the parents revealed a sickle S trait associated to heterozygous alpha thalassemia. His mother has Sickle cell anaemia (Hb SS) and his father is a carrier of heterozygous alpha-thalassemia status that it was unknown before.ConclusionThis case report describes a proliferative retinopathy in a 16 year-old patient with co-inheritance of heterozygous alpha + −thalassemia and sickle trait.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
