Burden of chronic kidney diseases and underlying causes in Zambia: evidence from the global burden of disease study 2019. BMC Nephrol 2023; 24:39. [PMID: 36800948 PMCID: PMC9938689 DOI: 10.1186/s12882-023-03078-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 02/01/2023] [Indexed: 02/20/2023] Open
Abstract
INTRODUCTION Chronic kidney disease (CKD) has been a global public health problem and a major source of suffering and poor quality of life for those afflicted. Using data from the global burden of disease (GBD) study 2019, we estimated the magnitude of the burden of CKD as well as the underlying causes of CKD in the Zambian population. METHOD The data used for this study were extracted from the GBD 2019 study. The GBD 2019 provides estimates of several metrics of disease burden including the commonly used disability-adjusted life year (DALYs) for over 369 diseases and injuries, and 87 risk factors and combinations of these in 204 countries and territories from 1990 to 2019. We estimated the burden of CKD as the number and rates (per 100,000 population) of DALYs, disaggregated by year, sex, and age group. We examined the underlying causes of CKD by estimating the population attributable fraction as the percentage contributions of risk factors to CKD DALY. RESULTS The number of DALYs for CKD was estimated as 76.03 million (95% UI: 61.01 to 93.36) in 2019 compared to 39.42 million (95% UI: 33.09 to 45.90) in 1990, representing 93% increase whereas the DALYs rate per 100,000 population was estimated as 416.89 (95% UI: 334.53 to 511.93) in 2019 compared to 496.38 (95% UI: 416.55 to 577.87) in 1990, representing 16% reduction. CKD due to hypertension accounted for 18.7% of CKD DALYs and CKD due to diabetes (types 1 and 2) accounted for 22.7%, while CKD from glomerulonephritis accounted for the most DALYs at 33%. The age group most impacted from CKD were adolescents and young adults. CONCLUSION The burden of CKD remains high in the Zambian population with diabetes, high blood pressure, and glomerulonephritis as important causes. The results highlight the need to develop a comprehensive action plan to prevent and treat kidney disease. Increasing the awareness of CKD among the public as well as adaptation of guidelines for treating patients with end stage kidney disease are important considerations.

Abstract
Glomerular diseases account for a significant proportion of chronic kidney disease in low-income and middle-income countries (LMICs). The epidemiology of glomerulonephritis is characterized inadequately in LMICs, largely owing to unavailable nephropathology services or uncertainty of the safety of the kidney biopsy procedure. In contrast to high-income countries where IgA nephropathy is the dominant primary glomerular disease, focal segmental glomerulosclerosis is common in large populations across Latin America, Africa, Middle East, and South East Asia, while IgA nephropathy is common in Chinese populations. Despite having a high prevalence of known genetic and viral risk factors that trigger focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis also is common in adults and children in some African countries. Treatment of glomerular diseases in adults and children in LMICs largely is dependent on corticosteroids in combination with other immunosuppressive therapy, which often is cyclophosphamide because of its ready availability and low cost of treatment, despite significant adverse effects. Partial and/or complete remission status reported from studies of glomerular disease subtypes vary across LMIC regions, with high rates of kidney failure, mortality, and disease, and treatment complications often reported. Improving the availability of nephropathology services and ensuring availability of specific therapies are key measures to improving glomerular disease outcomes in LMICs.

[PMID: 36625011 PMCID: PMC9898043 DOI: 10.7555/jbr.36.20220094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 07/31/2022] [Accepted: 08/04/2022] [Indexed: 01/11/2023] Open
Abstract
Lupus nephritis (LN) has a high incidence in systemic lupus erythematosus (SLE) patients, but there is a lack of sensitive predictive markers. The purpose of the study was to investigate the association between the CD4 +CD8 + double positive T (DPT) lymphocytes and LN. The study included patients with SLE without renal impairment (SLE-NRI), LN, nephritic syndrome (NS), or nephritis. Peripheral blood lymphocyte subsets were analyzed by flow cytometry. Biochemical measurements were performed with peripheral blood in accordance with the recommendations proposed by the National Center for Clinical Laboratories. The proportions of DPT cells in the LN group were significantly higher than that in the SLE-NRI group ( t=4.012, P<0.001), NS group ( t=3.240, P=0.001), and nephritis group ( t=2.57, P=0.011). In the LN group, the risk of renal impairment increased significantly in a DPT cells proportion-dependent manner. The risk of LN was 5.136 times (95% confidence interval, 2.115-12.473) higher in cases with a high proportion of DPT cells than those whose proportion of DPT cells within the normal range. These findings indicated that the proportion of DPT cells could be a potential marker to evaluate LN susceptibility, and the interference of NS and nephritis could be effectively excluded when assessing the risk of renal impairment during SLE with DPT cell proportion.

Management practice and treatment outcomes of adult patients with Lupus Nephritis at the Renal Clinic of St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia. BMC Nephrol 2022; 23:214. [PMID: 35715762 PMCID: PMC9206350 DOI: 10.1186/s12882-022-02846-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 06/08/2022] [Indexed: 12/01/2022] Open
Abstract
Background Lupus nephritis (LN) is the most common severe complication of systemic lupus erythematosus (SLE) which results in high morbidity and mortality. Up to 60% of adult patients with SLE develop the renal disease with different severity. Even with potent anti-inflammatory and immunosuppressive therapies, many LN patients still progress to chronic kidney disease or end-stage renal disease. Thus, this study aimed to assess the management practice, treatment outcomes and to identify the associated factors of poor renal outcome in adult LN patients at the renal clinic of St. Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia. Methods A retrospective cross-sectional study design was used to collect the data using an abstraction tool from patients’ records. The Kidney Disease Improving Global Outcomes (KDIGO) criteria were used to diagnose LN among SLE patients. Logistic regression was used to determine crude and adjusted odds ratio and a p-value of < 0.05 was considered statistically significant. Ethical approval was obtained from the ethical review committee of the School of Pharmacy, Addis Ababa University and institutional review board of St. Paul’s Hospital Millennium Medical College. Results Out of 168 study participants enrolled from September 1, 2016 to October 30, 2020, a total of 114 adult LN patients were included for final analysis. The mean (± SD) age of the LN patients at onset was 29.10 ± 9.67 years and 99 (86.8%) of all the patients were females. More than three-fourths (78.9%) of the LN patients had a good prognosis. However, 24 (21.1%) of the patients who didn’t achieve complete or partial remission had a poor prognosis. A kidney biopsy was done for 71 patients at initial presentation with class IV and III as the commonest class. The commonly prescribed immunosuppressive medications were cyclophosphamide as induction therapy in 67 (58.7%) and mycophenolate mofetil (MMF) as maintenance therapy in 76 (66.7%). Gastrointestinal intolerances like abdominal pain, nausea, or diarrhea from MMF were the most common 27(31.2%) treatment-related adverse events reported. Acute kidney injury (AKI) at onset (AOR = 4.83, P = 0.026), high serum creatinine (SCr) at six months (AOR = 0.12, P = 0.003), no response at six months to attain complete remission (AOR = 0.05, P = 0.041) and presence of flare (AOR = 0.04, P = 0.004) were predictors poor treatment outcomes. Conclusion Despite good response with the present immunosuppressive regimens, relapse, treatment-related complications and adverse events are major problems that require close monitoring. The results and identified gaps of this study are used as an input to improve the management practice of LN in the study setting. Overall, this study is comparable with other findings and strengthen the present available literatures.

Abstract
BACKGROUND Treatment of patients with lupus nephritis (LN) requires judicious use of immunosuppression. Novel biomarkers may be useful for monitoring disease activity and treatment response. We assessed the utility of urinary monocyte chemoattractant protein-1 (uMCP-1) and urinary tumour necrosis factor-like weak inducer of apoptosis (uTWEAK) for disease activity and treatment response monitoring in South Africans with LN. METHODS We recruited consenting patients with active LN confirmed on kidney biopsy. Urinary levels of MCP-1 and TWEAK were assayed at baseline and after completion of induction therapy using ELISA methods. We also collected relevant demographic, clinical and biochemical data for patients included in this study. RESULTS The mean age of patients in this study was 29.8 ± 10.7 years, 60% were patients of mixed ancestry, 70% had proliferative LN and mean spot urine proteinuria at baseline was 0.37 (0.18-0.59) g/mmolCr. At completion of induction therapy, the level of uMCP-1 had reduced to 314.5 (IQR: 197.0-622) pg/mgCr from a baseline of 1092.7 (IQR 578.6-1848) pg/mgCr (P = 0.06) while uTWEAK had reduced to 36.0 (IQR 17.0-88.0) pg/mgCr from 159.0 (IQR: 88.5-295.5) pg/mgCr (P = 0.03). For patients reaching early complete or partial remission (n = 17), both biomarkers had significantly declined in their urine: uMCP-1 (P = 0.018) and uTWEAK (P = 0.015). There was no reduction of both biomarkers in patients not achieving remission and no association between uMCP-1 or uTWEAK with renal histological features. CONCLUSION Our study shows that uMCP-1 and uTWEAK are elevated in patients with active LN, correlated with the remission status (response to treatment) at the end of induction therapy and can, therefore, be useful for monitoring disease activity and treatment response.

Abstract
Background Lupus nephritis (LN) can be complicated with requirement for kidney replacement therapy and death. Efficacy of induction therapies using mycophenolate mofetil (MMF) or intravenous cyclophosphamide (IVCYC) has been reported from studies, but there is limited data in Africans comparing both treatments in patients with proliferative LN. Methods This was a retrospective study of patients with biopsy-proven proliferative LN diagnosed and treated with either MMF or IVCYC in a single centre in Cape Town, South Africa, over a 5-year period. The primary outcome was attaining complete remission after completion of induction therapy. Results Of the 84 patients included, mean age was 29.6 ± 10.4 years and there was a female preponderance (88.1%). At baseline, there were significant differences in estimated glomerular filtration rate (eGFR) and presence of glomerular crescents between both groups (p ≤ 0.05). After completion of induction therapy, there was no significant difference in remission status (76.0% versus 87.5%; p=0.33) or relapse status (8.1% versus 10.3%; p=0.22) for the IVCYC and MMF groups, respectively. Mortality rate for the IVCYC group was 5.5 per 10,000 person-days of follow-up compared to 1.5 per 10,000 person-days of follow-up for the MMF group (p=0.11), and there was no significant difference in infection-related adverse events between both groups. Estimated GFR at baseline was the only predictor of death (OR: 1.0 [0.9-1.0]; p=0.001). Conclusion This study shows similar outcomes following induction treatment with MMF or IVCYC in patients with biopsy-proven proliferative LN in South Africa. However, a prospective and randomized study is needed to adequately assess these outcomes.

Abstract
BACKGROUND Renal involvement is common among Asians with systemic lupus erythematosus and long-term renal outcomes have been described in homogeneous Caucasian and East Asian populations with lupus nephritis, but data are scarce for other ethnicities. AIM To evaluate the incidence and risk factors for progressive chronic kidney disease (CKD) in multi-ethnic Southeast Asians with lupus nephritis. METHODS This is a single-centre retrospective cohort study of adults with biopsy-proven lupus nephritis diagnosed between May 2001 and May 2009. Demographic and clinical data were retrieved from electronic medical records. Patients were excluded if baseline comorbid, renal function or pharmacotherapy data were incomplete or if they default follow-up within 3 months from time of diagnosis. Primary outcome was progressive CKD, defined by end-stage renal disease or persistent doubling of serum creatinine or reduction in eGFR ≥50% for ≥3 months from baseline. RESULTS We studied 113 patients with newly diagnosed biopsy-proven lupus nephritis. Median age was 42 (interquartile range 29-52) years; the majority were Chinese (76%; Malay 13% and others 11%) and female (81%). Two-thirds had International Society of Nephrology and Renal Pathology Society Class III or IV nephritis; serum creatinine was 86 (67-125) μmol/L with heavy proteinuria (6.3 (2.5-12.2) g/g creatinine). Median follow-up was 110 (83-142) months. Remission (partial and complete) occurred in 96% at 3.1 (1.6-5.2) months after diagnosis. Among patients who achieved remission, 56% had disease relapse at 19.0 (6.0-40.2) months after remission. Patients with progressive CKD (n = 13, 11%) had lower baseline CKD Epidemiology Collaboration estimated glomerular filtration rate (37.3 (16.5-82.0) vs 79.4 (57.5-101.0) mL/min/1.73 m2 , P = 0.03) and higher chronicity index (5 (3-6) vs 3 (2-3), P = 0.04) than those who did not. Remission, early remission within 6 months, complete remission and non-relapse were less frequently associated with progressive CKD (P < 0.01). CONCLUSION Multi-ethnic Southeast Asians with biopsy-proven lupus nephritis had high remission rates and low incidence of progressive CKD. Progressive CKD was associated with poorer baseline renal function, higher histological chronicity index, failure to achieve remission and occurrence of relapse.

Abstract
There are varying observations on the influence of ethnicity on the clinical spectrum and response to treatment in lupus nephritis (LN). We studied a multiethnic South African LN cohort to determine the clinical manifestations, histological involvement and response to therapy. We reviewed the records of LN patients at Inkosi Albert Luthuli Central Hospital in Durban. There were 105 patients, 92.5% females and they comprised 49.1% Indians and 45.3% African Blacks. The mean age was 31.3 ± 12.5 years, and 41.5% had LN at first presentation of lupus. The most common histological classes were Class V alone in 34.9%, Class IV (± Class V) in 25.5% and Class III (±Class V) in 22.6%. The estimated glomerular filtration rate was reduced (<30 ml/min) at presentation in 15 (14.2%). Eighty-seven patients received therapy for LN. A response to induction therapy was noted in 81.6% and maintenance therapy (12 months) in 73.6%. Response to mycophenolate mofetil (MMF) was 80.4% and 68.4% during induction and maintenance therapy, respectively. There was no ethnic difference in the histological class or response to MMF but African Blacks had more severe renal disease at presentation. In conclusion, our multiethnic LN cohort shows a high prevalence of membranous LN and good response to treatment.

Abstract
Background Repeat renal biopsies in patients with lupus nephritis are usually done to guide treatment or to establish disease chronicity. Their value is not clear from available literature. There are also no available data in Africa to guide clinicians. Methods This was a retrospective study of patients undergoing a repeat renal biopsy between January 2003 and December 2014 from a single centre in Cape Town, South Africa. Relevant demographic, clinical and histological records of patients with repeat renal biopsies were documented. Comparison of data from first and second renal biopsy was performed. Results Forty-four patients had at least two biopsies done during the study period. Most patients were females (81.8%). The mean biopsy interval was 2.8 ± 1.8 (range 0.38–9.4) years. Proteinuria was the main indication for the repeat biopsy (36.1%). The glomerular filtration rate and proteinuria worsened between the two biopsies ( p = 0.001 and 0.019, respectively) suggesting disease progression. Most patients (65.4%) with a non-proliferative class of lupus nephritis at first biopsy progressed into a proliferative class, whereas patients with initial proliferative lupus nephritis at first biopsy (77.8%) remained as proliferative at repeat biopsy. Treatment was changed in 85% of patients at second biopsy. Conclusion Repeat renal biopsies in patients with lupus nephritis presents a useful means of assessing disease progression and provides guidance regarding modification of treatment. More studies are, however, required to evaluate the value of repeat biopsies and perhaps the need for protocol renal biopsies in patients with lupus nephritis.
