[Cross-sectional study of iron level during pregnancy at the Mohamed V Military Training Hospital, Rabat]. / Etude transversale du statut martial au cours de la grossesse à l'Hôpital Militaire d'Instruction Mohamed V, Rabat.

Iron deficiency is the most widespread nutritional disorder. Anaemia during pregnancy is common in developing countries. The purpose of this study was to check iron levels during pregnancy by evaluating laboratory indicators of iron deficiency. Our study was conducted in the Department of Obstetrics and Gynaecology of the Mohamed V Military Training Hospital (MVMTH) and included 66 patients monitored during three trimesters of pregnancy. Biochemical tests including ferritin, serum iron, CRP and blood counts were performed. The average age of patients was 28.3 years, with a standard deviation of 5.2. The prevalence of iron deficiency was 15.2% (n = 10), 25.8% (n = 17) and 42.2% (n = 28) in the first, second and third trimester, respectively. Anemia progressed from 10% (n = 7), 24% (n = 16) to 42% (n = 28). ANOVA test was used to compare the means for the parameters serum ferritin and iron, hemoglobin and hematocrit within the three trimesters. This showed a significant difference with p = 0.001. This study highlights a high prevalence of iron deficiency during pregnancy, especially in the third trimester, that would justify a systematic iron supplementation.

Hypovitaminosis D and prevalent asymptomatic vertebral fractures in Moroccan postmenopausal women.

BACKGROUND: Hypovitaminosis D is associated to accentuated bone loss. However, association between osteoporotic vertebral fractures (VFs) and vitamin D status has not been clearly established. OBJECTIVE: To determine serum vitamin D status and to assess the association of vitamin D status with bone mineral density (BMD) and asymptomatic VFs prevalence using vertebral fracture assessment (VFA) in a cohort of Moroccan menopausal women. METHODS: from June to September 2010, 178 menopausal women 50 years old and over were enrolled in this cross-sectional study. The mean ± SD (range) age, weight, height and BMI were 58.8 ± 8.2 (50 to 79) years, 73.2 ± 13.8 (35 to 119) Kgs, 1.56 ± 0.06 (1.43 - 1.79) m and 29.8 ± 5.9 (17.5 - 49.8) kg/m2, respectively. VFA images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genant semiquantitative approach and morphometry. Serum levels of 25-hydroxyvitamin D (25(OH)D) were measured. RESULTS: Among the 178 women, 45 (25.2%) had densitometric osteoporosis, and on VFA, VFs (grade 2 or 3) were detected in 20.2% while grade 1 were identified in 33.1%. The mean values of serum levels of 25(OH)D were 15.8 ± 11.6 ng/ml (range: 3.0 - 49.1) with 152 patients (85.3%) having levels <30 ng/ml (insufficiency) and 92 (51.6%) <10 ng/ml (deficiency). Stepwise regression analysis showed that presence of VFs was independently related to age, 25(OH)D and densitometric osteoporosis. CONCLUSION: our study shows that advanced age, hypovitaminosis D and osteoporosis are independent risk factors for asymptomatic VFs in Moroccan postmenopausal women.

[Sensitization to aeroallergens at Mohamed V Hospital (Rabat, Morroco)]. / Étude des IgE réactives aux pneumallergènes chez les consultants de l'hôpital militaire Mohamed V de Rabat (Maroc).

This transversal case study aimed at drawing the biological profile of sensitized patients consulting for respiratory allergies at Mohamed V Military Hospital-Rabat. One hundred four patients were included in the case study, who have benefitted from specialized medical consultation and those who came to the biochemistry laboratory holding a medical check-up prescription for allergy (NFS and biochemical check-up). The biochemical analysis were made up of TMA Phadiatop(®), correct proportioning of specific IgE serum, and complete IgE. The different anamnestic and clinical parameters acting upon the sensitization to respiratory allergens have been collected through a multiple choice question survey. Statistical analysis has been performed by a SPSS software version 13.0. The Phadiatop(®) was positive at 54.8% of our patients with a masculine predominance (H/F sex-ratio = 1.4). The recurring symptoms were the rhinitis (36.8%) and the asthma (10.5%). The allergen d1 Dermatophagoides pteronyssinus was the most incriminated pneumallergens (59.6%). For 19.3% of the patients sensitized, a polysensitization (superior to three) was noted, due to dust mite, cockroaches, pollen and animals. 93.6% of the Phadiatop(®) positive patient had a hypereosinophilia (p < 0.001). The complete IgE had been prescribed to 29 patients and had been increased among 19 patients in 66% of the cases. Among the patients having a rate of elevated complete IgE, 8 (42.1%) had a negative Phadiatop(®) (p = 0.019). Our survey showed the strong prevalence of the respiratory sensitization at our population. The allergen d1 is the most incriminated. It also put in evidence the weak diagnostic value of the dosage of the complete IgE in the respiratory allergy.

[Lipid profile of patients on chronic hemodialysis (Morocco)]. / Profil lipidique dans l'insuffisance rénale chronique au stade d'hémodialyse : étude marocaine.

INTRODUCTION: Patients with end-stage renal disease (ESRD) receiving chronic hemodialysis show a high incidence and prevalence of cardiovascular disease of multifactorial etiology and an association between dyslipidemia and accelerated atherosclerosis. OBJECTIVE: Our aim was to study lipid profiles in ESRD patients receiving dialysis regularly at our hospital (Morocco).Subjects and methods : The patient population consisted of 30 ESRD patients on maintenance haemodialysis. Matched control subjects were recruited among healthy normolipidemic patients. Concentrations of triglycerides (TG), total cholesterol (TC), high-density-lipoprotein cholesterol (HDL-C) and low-density-lipoprotein cholesterol (LDL-C) were measured. The atherogenic index (AI = TC/HDL-C ratio) was calculated. RESULTS: The TG, the HDL-C levels and atherogenic index were significantly higher in groups of hemodialysis patients. We saw no increase in the levels of TC and LDL-C. The prevalence of dyslipidemia in hemodialysis group was high (80%). The most frequent lipid alterations were decreased HDL-C (70%), increased TG (33,3%) and increased LDL-C (23,3%); 50% of ESRD patients have more than two different dyslipidemic findings. AI was higher (≥ 5) in 33,3% of cases. CONCLUSION: The prevalence of dyslipidemia is higher than normal in ESRD patients on maintenance hemodialysis. Classically, these patients have had low levels of HDL-C and elevated TG levels. Strict control of dyslipidemia should be part of the cardiovascular risk prevention strategy in this population.

Bone turnover markers, anterior pituitary and gonadal hormones, and bone mass evaluation using quantitative computed tomography in ankylosing spondylitis.

The objective of this study was to determine bone mineral density (BMD) distribution in ankylosing spondylitis (AS) using quantitative computed tomography (QCT), to study bone turnover and anterior pituitary and gonadal hormonal axis in AS, and to look for correlations between BMD, bone remodeling markers and gonadal and anterior pituitary hormones. Forty-three male consecutive patients with AS were enrolled prospectively [mean (SD) age of 36.4 (11.3) years (range: 17-67) and mean disease duration of 6.8 (5.2) years (range: 0.4-19)]. Spine BMD was measured in all patients by QCT, and the results were compared to 29 male patients undergoing lumbar CT scan for sciatica. Bone turnover and anterior pituitary and gonadal axis were assessed in 29 patients, and the results were compared to 30 male healthy blood donors. The mean (SD) BMD was 127.7 mg/cm(3) (48.9) (range: 8.8-265.7) and 152.1 (25.3) (range: 34.2-190.4) in patients and controls, respectively (p = 0.018). Patients had lower serum levels of osteocalcin and higher levels of serum testosterone, luteinizing hormone (LH), and prolactin than controls with a significant statistical difference. There was a positive significant statistical correlation between BMD and chest expansion, Schober's test, C7-wall distance, and negative significant statistical correlation with age, disease duration, Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Radiology Index (BASRI), and serum prolactin. No correlation was observed between bone turnover parameters and AS symptomatic and structural severity indexes. BMD is lower with increasing age and late and severe disease. Decreased bone formation with normal resorption and increased levels of serum prolactin may be involved in its pathophysiology.

Bone metabolism in male patients with type 2 diabetes.

Few reports are available on bone turnover in type 2 diabetes. Impaired bone turnover in type 2 diabetes appears to result from decreased bone formation. Studies also suggest that poor glycaemic control in type 2 diabetes may contribute to osteopaenia. The aim of this study was to investigate biochemical markers of bone turnover in males with poorly controlled type 2 diabetes and look for correlations with glycaemic control and gonadal and hypophyseal hormonal axis. Consecutive male patients with poorly controlled type 2 diabetes and attending the internal medicine department during a period of 6 months were enrolled. The patients were receiving oral hypoglycaemic agents (metformin or sulphonylureas or both). None of the patients had any evidence of macroangiopathy, nephropathy or neuropathy. Only two patients had proliferative retinopathy. Serum osteocalcin, crosslaps (C-telopeptide, CTx), parathyroid hormone (PTH), testosterone, oestrogen, prolactin, follicle-stimulating hormone (FSH) and luteinising hormone (LH) were measured in 35 patients and 35 controls. The mean age of the study population was 53.7 (10.3) years (range: 50.2-57.3) and the mean disease duration was 8.6 (6.0) years (range: 6.5-10.7). No differences between patients and controls were observed in serum calcium, phosphorus, creatinine, albumin, PTH, CTx, oestrogen, testosterone, LH, FSH, prolactin and urinary calcium. Patients had lower serum levels of osteocalcin than controls with a significant statistical difference [15.3 (4.1) vs 18.3 (5.3), p=0.012]. There was a negative significant statistical correlation between CTx levels and HbA1c (r=-0.41, p< 0.05). Our study suggested that bone formation is altered in type 2 diabetes and that bone turnover is affected by glycaemic control status.

Serum tumor markers in hemodialysis patients.

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.

[Utility of hCG dosage in the management of gestational trophoblastic diseases]. / Intérêt du dosage de l'hormone chorionique gonadotrope dans les maladies trophoblastiques gestationnelles.

Measurement of hCG remains today central for diagnosis, treatment and follow-up of gestational trophoblastic diseases (GTD). In order to evaluate this contribution, we conducted a prospective cohort study in the Service of high-risk pregnancy of Rabat Maternity Les Orangers and the Laboratory of Rabat Military Teaching Hospital Mohammed V over a period of eighteen months. 35 patients were included. The hCG assay was determined by electrochemiluminescence. The general frequency of the GTD is of 0.33/100 childbirth. The average age of our patients was 30.5 years. 26 patients had hCG level abnormal and higher than 200 000 UI/mL when diagnosed with GTD; 34 patients had simple endo-uterine aspiration and 1 a chemotherapy. Among 34 patients, 25 (73.5%) had a favourable evolution characterized by normal hCG level within 3 to 13 weeks and complete remission. Serum hCG remained stable and negative in all these patients with a follow-up of 18 months. 9 patients had unfavourable evolution characterized by reaxent after negativation or stagnation of hCG levels. A rigorous monitoring of hCG levels during treatment and follow-up is essential to improve forecast of these diseases.
