RELATIONSHIP BETWEEN SICKLE CELL NEPHROPATHY AND SOME BIOCHEMICAL MARKERS OF HAEMOLYSIS AMONGST PATIENTS WITH SICKLE CELL ANAEMIA IN KANO, NORTHWESTERN NIGERIA

Introduction

Advancements in the care of patients with sickle cell anaemia have led to significant improvement in survival with many patients reaching adulthood. As they age, long-term complications of the disease manifest in them, notable amongst which is nephropathy which is one of the leading causes of morbidity and mortality in them. There is limited information about sickle cell nephropathy and some biochemical markers of haemolysis that can detect it early in our setting. This study aimed to determine the relationship between some indirect markers of haemolysis and sickle cell nephropathy.

Methodology

The study was a descriptive cross-sectional one where 204 adolescent and adult patients with sickle cell anaemia attending the clinic of AKTH Kano were recruited. An interviewer-administered questionnaire was utilized. Blood samples were taken for determination of serum bilirubin, LDH, and reticulocyte count. Spot urine was used to quantitatively determine albumin to creatinine ratio. Data collated was analyzed using SPSS version 22.0. P-value <0.05 was considered significant.

Result

Two hundred and four (204) participants were enrolled in to the study. Their mean age was 19.6±5years. Females were the majority 131/204 (64.2%). The median (IQR) serum lactate dehydrogenase, bilirubin, direct bilirubin, and reticulocyte count were 607.0(487.3-758.5) U/L, 54.5(37.0-119.0) umol/L, 16.0(11.3-29.0) umol/L and 4.0(3.0-8.4%) respectively. Sickle cell nephropathy was found in 29/204 (14.2%). There were positive significant associations between sickle cell nephropathy with raised serum bilirubin and serum lactate dehydrogenase (p-value = 0.02 and 0.032 respectively).

Conclusion

Sickle cell nephropathy is common amongst patients with sickle cell anaemia and raised serum bilirubin and lactate dehydrogenase are predictors of sickle cell nephropathy.

Correlation between Red Cell Distribution Width and Glycaemic Control among Adults with Type II Diabetes Mellitus at Aminu Kano Teaching Hospital, North-Western Nigeria

BACKGROUND

Red Blood Cell Distribution Width (RDW) measures the degree of variation in red blood cell size and it is a good predictor of complications in many conditions such as diabetes mellitus (DM). This study aimed to determine the relationship between RDW and glycaemic control in patients with type II DM.

MATERIALS AND METHODS

It was a cross-sectional comparative study where patients with type II DM and apparently healthy non-DM volunteers were recruited. Blood samples were collected and analysed for RDW, Fasting Plasma Glucose (FPG) level and Glycated Haemoglobin (HbA1c). Data were analyzed using Statacorp version 13.

RESULTS

A total of 180 participants were enrolled (90 cases, 90 controls). The mean (±SD) ages of cases and controls were 42 (± 11.94) and 34 (± 9.5) years, respectively. Females constituted the majority (49/90; 54.4%) in both groups. The cases had higher RDW than the controls (15.5 ± 1.0% versus 14.3 ± 1.7 %, p=0.630). The correlation between RDW and HbA1c revealed a weak statistically significant relationship (r=0.096, p=0.03) while a weak negative relationship was observed between the RDW and FPG (r = -0.006, p=0.956) which was not statistically significant. However, a negative finding showed a positive correlation between RDW and MCH (p-value = 0.003) and MCHC (p-value = 0.0002).

CONCLUSION

Red cell distribution width has a direct relationship with HbA1c in patients with DM. Therefore, we recommend that clinicians pay attention to this detail while evaluating patients with DM.

Acute Leukaemias in Bauchi State, Northeastern Nigeria: Pattern of Presentations and Clinical Entities

BACKGROUND

Acute leukaemias are very aggressive diseases that run a rapidly fatal course if not promptly diagnosed and appropriately treated. The clinical presentations range from bone marrow failure such as anaemia, neutropenia or thrombocytopenia to features of organ infiltrations such as lymphadenopathy, splenomegaly, etc, but presentations may be non-specific. Misdiagnosis is very common with delay in diagnosis and prompt treatment being the causes of high morbidity and mortality in acute leukaemias. This study aims to determine the pattern of presentation and various clinical entities of acute leukaemias in Bauchi State, North-Eastern Nigeria.

SUBJECTS, MATERIALS AND METHODS

This was a three year retrospective study in which records of cases of acute leukaemias diagnosed in the Haematology Department of Abubakar Tafawa Balewa University Teaching Hospital (ATBUTH) Bauchi from the bone marrow aspiration cytology register from 1st January, 2018 to 31st December, 2020 were collected. Data on socio-demographic characteristics of the patients that include age, gender, diagnosis as well as subtypes of some of the malignancies diagnosed were also collated. The collated data were analyzed using SPSS Version 20.0. A p-value of < 0.05 was considered significant.

RESULTS

Twenty-nine cases of acute leukaemias were diagnosed during the period under review. Majority of cases had acute lymphoblastic leukaemia (ALL) 19/29 (65.5%) while acute myeloid leukaemia (AML) was seen in 10/29 (34.5%). The mean ± SD age of the patients was 22.2±9.2 years with a range 6 months to 60 years. Males constituted 75.9% (22/29) of the cases of acute leukaemias diagnosed. The male to female ratios for AML and ALL were 2:1 and 2.6:1 respectively. The mean±SD ages for AML and ALL were 27±9.2years and 17.3±11.3 years respectively. The most common form of presentation of acute leukaemia in this study is recurrent anaemia necessitating blood transfusion while proptosis and epistaxis were the least forms of presentation.

CONCLUSION

Acute lymphoblastic leukaemia is the commonest form of acute leukaemias while recurrent anaemia is the commonest form of clinical presentations in our setting. Early referral of patients with clinical features suggestive of acute leukaemias is recommended.
