Correlation between the plasma fibrinogen concentration and coronary heart disease severity in Moroccan patients with type 2 diabetes. Prospective study.

AIM: The present study aims at determining the relationship between the plasma fibrinogen concentration and the severity of coronary heart disease in type 2 diabetic patients. METHODS: Prospective analytical survey, based on a sample of 120 subjects divided in four groups: 30 non diabetic coronary patients (G1), 30 coronary diabetic patients (G2), 30 non-coronary diabetic patients (G3), and 30 healthy subjects (G4). RESULTS: The average age was 59.58±7.88 years; female gender predominated by 52.5%. The plasma fibrinogen concentration corresponded to 3.46g/L±0.86 in G1; 3.73g/L±1.11 in G2; 3.06g/L±0.98 in G3 and 2.46g/L±0.51 in G4; with a significant difference between the four groups (P=0.001). The plasma fibrinogen concentration increased in parallel with the cardiovascular risk (P=0.0001); there was also a significant correlation between the plasma fibrinogen concentration and the clinical and para-clinical coronary disease severity (respectively P=0.005 and P=0.0001). A positive correlation between the plasma fibrinogen concentration and hyperglycemia (P=0.035) was found in G4. But no correlation with the lipids parameters, except for the low density-lipoproteins in G3 (P=0.035). CONCLUSION: In the Moroccan population, the plasma fibrinogen concentration was positively and significantly correlated with the coronary heart disease severity.

Hematology reference intervals in Moroccan population.

BACKGROUND: Laboratory reference intervals are important for both clinical orientations and therapeutic decisions. In Morocco, no reference ranges are available for local population. The ranges commonly used in clinical laboratories and by physicians are those of Caucasian population. We have decided that it is relevant to undertake an epidemiological investigation on local adult healthy population, with the aim of establishing hematology reference intervals in Moroccan population. METHODS: Blood samples were taken from healthy adult volunteers of the regional transfusion center and measured on a Sysmex XE-2100 analyzer. We have grouped our data samples with regard to gender and retained donors aged between 18 and 45 years old according to ICSH guidelines 1982. Leucocyte, erythrocyte, and platelet parameters were analyzed. For any sample flagged by the automate or thrombopenia with platelets < 100000/microL, a systematic smear was done and checked. RESULTS: A significant difference between male and female was found with regard to the values for leucocyte, erythrocyte, and platelet parameters as well as for hemoglobin and hematocrit. These data were compared to normal values reported for Arabic, Caucasian, and African population. CONCLUSIONS: As part of this study, we have given a descriptive approach of normal blood cell count and its peculiarities in North African Arabian and Berber population not explored until now. We have established similarities and differences between our population and other African, Arab, and Caucasian populations.

Prevalence and risk factors of hepatitis B and C virus infections among the general population and blood donors in Morocco.

BACKGROUND: Viral hepatitis is a serious public health problem affecting billions of people globally. Limited information is available on this issue in Morocco. This cross-sectional study was undertaken with the aim of determining the seroprevalence and risk factors of hepatitis B virus (HBV) and hepatitis C virus (HCV) among the general population and among blood donors. METHODS: Blood samples from volunteers, have been screened with ELISA tests for detecting the hepatitis-B surface antigen (HBsAg) and anti-HCV. Within the seroreactive patients for HCV in the general population, RT-PCR was performed by the Cobas Ampliprep/Cobas Amplicor. RESULTS: HCV and HBV-seropositivity was documented in 1.58% and 1.81% out of 41269 and 23578 participants respectively from the general population. Two patients were found to be co-infected. HCV-RNA was detected by PCR in 70.9% of the 195 anti-HCV positive subjects. The anti-HCV prevalence was not different among males and females (P = 0.3). It increased with age; the highest prevalence was observed among subjects with >50 years old (3.12%). Various risk factors for acquiring HCV infection were identified; age, dental treatment, use of glass syringes and surgical history. In addition to these factors, gender and sexual risk behaviors were found to be associated with higher prevalence of hepatitis B. The HBV positivity was significantly higher among males than females participants in all age groups (P < 0.01). The peak was noticed among males aged 30-49 years (2.4%). None of the 152 persons younger than 20 years had HBsAg or anti-HCV. The prevalence of anti-HCV and HBsAg among 169605 blood donors was 0.62% and 0.96% respectively. CONCLUSIONS: Our study provided much important information concerning hepatitis B and C prevalence and risk factors; it confirmed the intermediate endemicity for HCV infection and pointed to a decreasing trend of HBV incidence, which might reclassify Morocco in low HBV endemicity area. This could be attributed primarily to the universal HBV vaccination among infants and healthcare workers over the past 13 years. HCV and HBV infections in the present survey were mainly associated with nosocomial exposures. Prevention and control of HBV infection are needed to reduce HBV transmission between adults.
