Background: A disturbed glucose metabolism is quite common during pregnancy. It is due to the diabetogenic potential of pregnancy and responsible for many obstetric complications. The glycated hemoglobin is one of the markers used to depict these disorders. Higher concentrations of this marker would be associated with unfavorable results of pregnancy. Objective: To describe the profile of HbA1c in non-diabetic preeclamptic pregnant women and to establish the association between the values of this marker and the maternal and fetal complications. Materials and Method: This is a case-control study of 142 pregnant women in their second and third trimester. They were followed in the maternity hospitals of University Clinics and the General Reference Hospital in Kinshasa, Democratic Republic of Congo between May and October 2019. The sampling of preeclamptic pregnant women was exhaustive. Controls were healthy pregnant women carrying pregnancies of the same type and of the same gestational age as the cases. Ultimately, 71 were preeclamptic and 71 healthy (controls). HbA1c was determined by immunoturbidimetry. Results: A total of 142 pregnant women took part in this study consisting of 71 preeclamptic women (cases) and 71 healthy pregnant women (controls). The average age of these pregnant women was 28.8 ± 6.8 (28.2 ± 6.8 years vs 29.5 ± 6.8 years p = 0.559), with an average parity of 2.3 ± 1.5 (2.2 ± 1.7 vs 2.4 ± 1.2, p = 0.005). The majority were carriers of monofoetal pregnancy. Higher HbA1c values were observed in the preeclamptic pregnant women compared to the controls (5.7 ± 1.3% vs 4.8 ± 0.7%, p 0.001). The proportion of pregnant women with pathological HbA1c values (>5.6%) was also higher in the group of preeclamptic pregnant women (46.5% vs 9.9%, p Conclusion: This study established that 46.5% of non-diabetic pregnant women with preeclampsia have high HbA1c values, which moreover are associated with preeclampsia and its complications. Systematic screening is essen

Objectives: To determine the multiple myeloma (MM) prognostic formulas applicable in Congolese with many aberrant and/or immature plasma cells according to GOASGUEN’s plasma cell morphology algorithm (PMA). Methods: The prospective, observational and descriptive study was carried out at the Ngaliema Clinic in Kinshasa from July 2016 to December 2019. The variables studied were the plasma cell types and the prognosis groups according to GOASGUEN and ZANDECKI. The nucleolus, the chromatin and the N/C ratio of 2 for each plasma cell encountered in multiple myeloma are examined in order by asking three successive questions as follows: 1) Is the nucleolus present? If yes, we denote 1;if not, note 0;2) Is the chromatin thin? If yes, we score 1;if not we score 0;3) The N/C ratio is greater than 6, if so, 1 is noted;if not, we note 0. We obtain a number with 3 successive digits preceded by the letter P for each plasma cell. Results: The overall rate of immature plasma cells and aberrant plasma cells in MM among Congolese was high at 26.6%. Their integration in the prognostic formulas showed for group A" = 22 patients, group B" = 5 patients and group C" = 32 patients. Examination of plasma cell types in the deceased showed that 14/17 had a P001 plasma cell count ≥ 15%. Conclusion: The high rate of aberrant and/or immature plasma cells, the P001 plasma cell type at a rate ≥ 15%, found mostly in group C" with poor prognosis, are responsible for the aggressive nature of MM in Congolese Blacks.
