Chronic Kidney Disease Management in the Middle East and Africa: Concerns, Challenges, and Novel Approaches.

The burden of chronic kidney disease (CKD) and other comorbidities, such as hypertension and diabetes, which increase the risk of developing CKD, is on the rise in the Middle East and Africa. The Middle East and Africa CKD (MEA-CKD) steering committee, comprising eminent healthcare specialists from the Middle East and Africa, was formed to identify and propose steps to address the gaps in the management of CKD in these regions. The current article lists the MEA-CKD steering committee meeting outcomes and evaluates the available evidence supporting the role of novel therapeutic options for patients with CKD. The need of the hour is to address the gaps in awareness and screening, early diagnosis, along with referral and management of patients at risk. Measures to bring about appropriate changes in healthcare policies to ensure access to all benefit-proven protective therapies, including novel ones, at community levels are also vital for reducing the overall burden of CKD on the healthcare system as well as governing bodies, especially in developing countries of the Middle East and Africa.

Diagnostic values of CD64, C-reactive protein and procalcitonin in ventilator-associated pneumonia in adult trauma patients: a pilot study.

BACKGROUND: Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infections; however, its diagnosis remains difficult to establish in the critical care setting. We investigated the potential role of neutrophil CD64 (nCD64) expression as an early marker for the diagnosis of VAP. METHODS: Forty-nine consecutive patients with clinically suspected VAP were prospectively included in a single-center study. The levels of nCD64, C-reactive protein (CRP), and serum procalcitonin (PCT) were analyzed for diagnostic evaluation at the time of intubation (baseline), at day 0 (time of diagnosis), and at day 3. The receiver operating characteristic curves were analyzed to identify the ideal cutoff values. RESULTS: VAP was confirmed in 36 of 49 cases. In patients with and without VAP, the median levels (interquartile range, IQR) of nCD64 did not differ either at baseline [2.4 (IQR, 1.8-3.1) and 2.6 (IQR, 2.3-3.2), respectively; p=0.3] or at day 0 [2 (IQR, 2.5-3.0) and 2.6 (IQR, 2.4-2.9), respectively; p=0.8]. CRP showed the largest area under the curve (AUC) at day 3. The optimum cutoff value for CRP according to the maximum Youden index was 133 mg/dL. This cutoff value had 69% sensitivity and 76% specificity for predicting VAP; the AUC was 0.73 (95% CI, 0.59-0.85). The nCD64 and PCT values could not discriminate between the VAP and non-VAP groups either at day 0 or day 3. CONCLUSIONS: The results of this pilot study suggest that neutrophil CD64 measurement has a poor role in facilitating the diagnosis of VAP and thus may not be practically recommended to guide the administration of antibiotics when VAP is suspected.

Prevention of renal disease progression and renal replacement therapy in emerging countries.

Chronic kidney disease is increasing in both developed and emerging countries with progressive encroachment on health services budgets. In spite of the lack of accurate registries, we tried to focus on the magnitude of the problem on different continents. Prevention of progression has been a remote but reachable goal. Many health foundations including the International Society of Nephrology gave recommendations for prevention and slowing progression, but these are again confronted by lack of resources. Integration of governmental, community, and expert efforts is necessary to set prevention priorities including affordable screening programs and increasing access to renal replacement therapy by different modalities.
