A look at risk factors of proteinuria in subjects without impaired renal filtration function in a general population in Owerri, Nigeria

Early detection of renal disease among truck drivers through organized screening

BACKGROUND

Trucking industry is the backbone of trade and economy and in India, truck drivers are occupationally faced with various challenges. Several risk factors including stress and abnormal lifestyle predisposes this group to non-communicable disease and chronic kidney disease (CKD) is one of the major threats. This study was carried out to evaluate the prevalence and risk factors of chronic kidney disease.

METHODS

The present cross-sectional study was carried out as a population-based screening programme among 3,200 truck drivers in Tamil Nadu for a period of 1 year in 2018. A structured proforma was used to obtain information regarding the diabetic and hypertensive status. Body mass index was calculated and blood pressure was measured using standard equipments. Urine dipstick method was used to detect the presence of albumin and glucose in the urine.

RESULTS

The mean age of the participants was 40.3 years. Overweight and obesity was seen in 49.9% of the participants, while elevated blood pressure was observed in 41.1%. About 12.4% of the participants were known hypertensives on medications. Albuminuria was present in 19.7% of the participants. Albuminuria was significantly associated with elevated blood pressure, high body mass index and elevated random blood sugars (P < 0.0001). In 83.7% of the participants, random blood sugar was elevated beyond 200 mg/dl.

CONCLUSION

The screening programme can be enhanced when coupled with an awareness campaign, with due focus on culturally relevant information delivered by trained health educators in the native language, so as to bring about adequate education through effective communication.

Prevalence and burden of chronic kidney disease among the general population and high-risk groups in Africa: a systematic review

OBJECTIVES

While increasing attention is paid to the rising prevalence of chronic diseases in Africa, there is little focus on chronic kidney disease (CKD). This systematic review assesses CKD burden among the general population and high-risk groups on the entire African continent.

DESIGN, SETTING AND PARTICIPANTS

We searched Medline and PubMed databases for articles published between 1 January 1995 and 7 April 2017 by sensitive search strategies focusing on CKD surveys at the community level and high-risk groups. In total, 7918 references were evaluated, of which 7766 articles were excluded because they did not meet the inclusion criteria. Thus, 152 studies were included in the final analysis.

OUTCOME MEASUREMENT

The prevalence of CKD in each study group was expressed as a range and pooled prevalence rate of CKD was calculated as a point estimate and 95% CI. No meta-analysis was done. Data were presented for different populations.

RESULTS

In the community-level studies, based on available medium-quality and high-quality studies, the prevalence of CKD ranged from 2% to 41% (pooled prevalence: 10.1%; 95% CI 9.8% to 10.5%). The prevalence of CKD in the high-risk groups ranged from 1% to 46% (pooled prevalence: 5.6%; 95% CI 5.4% to 5.8%) in patients with HIV (based on available medium-quality and high-quality studies), 11%-90% (pooled prevalence: 24.7%; 95% CI 23.6% to 25.7%) in patients with diabetes (based on all available studies which are of low quality except four of medium quality) and 13%-51% (pooled prevalence: 34.5%; 95 % CI 34.04% to 36%) in patients with hypertension (based on all available studies which are of low quality except two of medium quality).

CONCLUSION

In Africa, CKD is a public health problem, mainly attributed to high-risk conditions as hypertension and diabetes. The poor data quality restricts the validity of the findings and draws the attention to the importance of designing future robust studies.
