RESUMO
INTRODUCTION: The severity of lupus nephritis (LN) varies between different ethnicities. However, there are limited data regarding disease severity for LN in patients from the Arabian Gulf region; moreover, there are no treatment guidelines developed specifically for this population. The objective of this review was to characterise the incidence of LN, current treatment practices, the severity of LN, and the pathophysiology and biomarkers associated with LN in the Arabian Gulf region. METHODS: A literature search using EMBASE was conducted in October, 2021 to identify publications reporting on the incidence, treatment practices, severity, pathophysiology or biomarkers associated with LN, from countries in the Arabian Gulf region (including Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates). Additional relevant publications were provided by collaborators. A manual review of the publications was conducted to determine their relevance and data on the outcomes of interest were extracted. RESULTS: Of 3705 publications, 54 publications were identified as relevant. LN is one of the most commonly diagnosed renal diseases within the Arabian Gulf and approximately 10%-36% of all renal biopsies are for LN. Treatment patterns within the region appear to vary and generally follow treatment guidelines recommended by the Asia Pacific League of Associations for Rheumatology (APLAR), the European Alliance of Associations for Rheumatology (EULAR) and Kidney Disease Improving Global Outcomes (KDIGO). The majority of patients receive cyclophosphamide for induction therapy, whilst others receive mycophenolate mofetil. Most studies showed that the most frequently diagnosed class of LN within the Arabian Gulf region was Class IV (up to 63% of patients with LN). Sustained or increased levels of serum creatinine and proteinuria; and depressed levels of complement C3/C4 were commonly seen among patients with LN from the Arabian Gulf region. CONCLUSIONS: This review identified that LN may manifest more severely among patients from the Arabian Gulf region than in other populations, such as Caucasian populations. A greater understanding of LN and the treatment practices within the region, as well as the development of more specific treatment guidelines for this population may help improve outcomes for patients with LN in the Arabian Gulf region.

BACKGROUND: In the Commonwealth of Independent States (CIS) countries epidemiology of Bronchial Asthma (BA) is poorly characterized. The objective of this analysis is to present the prevalence, burden and risk factors associated with BA in the CIS countries as part of the CORE study (Chronic Obstructive REspiratory diseases). METHODS: A total of 2842 adults (≥18 years) were recruited (964 in Kiev, Ukraine, 945 in Almaty, Kazakhstan, and 933 in Baku, Azerbaijan) in 2013-2015 during household visits. A two-step cluster random sampling strategy was used. All respondents were interviewed about respiratory symptoms, smoking, medical history. Two definitions were used: (i) "doctor diagnosed asthma" when the respondent reported that he/she had ever been diagnosed with BA by a doctor, (ii) "wheezing symptoms" (when the respondent reported wheezing at the ATS Respiratory Symptoms Questionnaire during the study) using GINA (2012) recommendations. Chi-square tests were used to assess differences in proportions. Binary logistic regression was used to estimate odds ratios (OR) and 95% CI for association between risk factors and BA. RESULTS: Prevalence of "doctor diagnosed asthma" was 12.5, 19.0 and 26.8 per 1000 persons, and prevalence of "wheezing symptoms" was 74.4, 254.8 and 123.4 per 1000 in Ukraine, Kazakhstan, and Azerbaijan, respectively. Statistically significant relationship with "wheezing symptoms" was shown for smoking (OR 1.99 (CI 1.22-3.27) in Ukraine, 2.08 (CI 1.54-2.81) in Kazakhstan, 8.01 (CI 5.24-12.24) in Azerbaijan); overweight/obesity (OR: 1.66 (CI 1.02-2.72); 1.94 (CI 1.44-2.62); 1.77 (CI 1.18-2.68), respectively) and dusty work (OR: 3.29 (CI 1.57-6.89); 1.68 (CI 1.18-2.39); 2.36 (CI 1.56-3.59), respectively), and for tuberculosis in Azerbaijan (OR: 10.11 (CI 3.44-29.69)). Co-morbidities like hypertension, cardiovascular diseases, abnormal blood lipids and a history of pneumonia occurred significantly (p < 0.05) more frequently in respondents with BA compared to those without BA across all participating countries. CONCLUSION: In CIS countries (Ukraine, Kazakhstan and Azerbaijan) the prevalence of doctor diagnosed asthma was significantly lower compared to prevalence of wheezing symptoms underlining that BA is likely to be underreported in these countries. The information provided in this paper will be helpful for healthcare policy makers in CIS countries to instruct BA management strategies and to allocate healthcare resources accordingly.

RESUMO
BACKGROUND: Main treatable Chronic Respiratory Diseases (CRDs) like Chronic Obstructive Pulmonary Disease (COPD), Bronchial Asthma (BA) and Allergic Rhinitis (AR) are underdiagnosed and undertreated worldwide. CORE study was aimed to assess the point prevalence of COPD, BA and AR in the adult population of major cities of Commonwealth of Independent States (CIS) countries - Azerbaijan, Kazakhstan, and Ukraine based on study questionnaires and/or spirometry, and to document risk factors, characterize the COPD, BA and AR population to provide a clearer "epidemiological data". METHODS: A descriptive, cross-sectional, population-based epidemiological study conducted from 2013 to 2015 with two-stage cluster geographical randomization. Interviewers conducted face-to-face visits at respondent's household after informed consent and eligibility assessment including interviews, anthropometry, spirometry (with bronchodilator test) and completion of disease-specific questionnaires. RESULTS: Two thousand eight hundred forty-two respondents (Ukraine: 964 from Ukraine; 945 from Kazakhstan; 933 Azerbaijan) were enrolled. Mean age was 40-42 years and males were 37%-42% across three countries. In Kazakhstan 62.8% were Asians, but in Ukraine and in Azerbaijan 99.7% and 100.0%, respectively, were Caucasians. Manual labourers constituted 40.5% in Ukraine, 22.8% in Kazakhstan and 22.0% in Azerbaijan, while office workers were 16.1%, 31.6% and 36.8% respectively. 51.3% respondents in Ukraine, 64.9% in Kazakhstan and 69.7% in Azerbaijan were married. CONCLUSION: CORE study collected information that can be supportive for health policy decision makers in allocating healthcare resources in order to improve diagnosis and management of CRDs. The detailed findings will be described in future publications. TRIAL REGISTRATION: Study Protocol Summary is disclosed at GlaxoSmithKline Clinical Study Register on Jun 06, 2013, study ID 116757 .

PURPOSE: The LEUKOSPECT study aimed to describe health service utilization and to estimate the direct medical costs (DMCs) of chronic lymphocytic leukemia (CLL) in 2013 in the adult population of three post-Soviet countries - Russia, Ukraine, and Kazakhstan. As oncologic medical care is provided by federal state-owned, specialized medical institutions, the cost estimation in this study primarily informs from a state budget perspective. Patients' contributions to medical costs were not included in the cost evaluation. PATIENTS AND METHODS: This was a multinational, multicenter, retrospective study conducted in eight specialized centers (four in Russia, three in Ukraine, and one in Kazakhstan). The investigators captured data from the medical documents of all adult patients with an established CLL diagnosis before December 31, 2013, and who made at least one visit to their respective center between January 1 and December 31, 2013. RESULTS: A total of 319 adult CLL patients were enrolled (124 in Kazakhstan, 106 in Russia, and 89 in Ukraine). In 2013, the DMCs of CLL management (without CLL therapy) were 215.40 in Kazakhstan, 1,342.20 in Russia, and 13,260.70 in Ukraine. Hospitalizations formed the largest proportion of total cost: 18.1%, 23.1%, and 40.4%, respectively. The mean cost of CLL medical treatment was 13,580.60 (Russia), 399.40 (Kazakhstan), and 7,453.00 (Ukraine). CONCLUSION: CLL treatment standards varied across the selected countries; higher usage of biologic therapy was noted in Russia. Future research is needed to assess DMCs which include CLL treatment, which is another essential factor contributing to CLL DMCs.
RESUMO
PURPOSE: To investigate (in a post hoc analysis of the 2-year CONDUCT study) the characteristics and clinical outcomes of men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression who benefitted from lifestyle changes alone. METHODS: Patients were given lifestyle advice and randomized to a fixed-dose combination (FDC) of dutasteride and tamsulosin or watchful waiting (WW) and followed for 24 months. Patients in the WW group were escalated to tamsulosin if any follow-up International Prostate Symptom Score (IPSS) was equal or greater than the baseline value. Improvements in symptoms (change in IPSS) and quality of life [measured by BPH Impact Index (BII) and question 8 of the IPSS (IPSS-Q8)] were analysed in the FDC group, men who initiated tamsulosin (WW-TAM) and men who received no medical intervention (WW-no treatment) and the impact of baseline variables on IPSS determined. RESULTS: The adjusted mean decrease in IPSS, BII and IPSS-Q8 at each post-baseline visit over 24 months appeared greater in the FDC (n = 369) and WW-no treatment groups (n = 144) than in the WW-TAM group (n = 229). IPSS improvements appeared similar in the FDC group and WW-no treatment subgroup, except in patients with the greatest degree of bother at baseline (BII 7-13). CONCLUSION: BII at baseline may be a more relevant indicator than symptom severity as to whether a patient with moderate symptoms should receive medical therapy or not.

OBJECTIVES: LEUKOSPECT was a retrospective, multicenter, epidemiologic study carried out in Russia and Ukraine, aiming to assess the prevalence and cumulative 5-year incidence of chronic lymphocytic leukemia (CLL) in the adult population. METHODS: All data were collected manually from patient medical records at each of the study sites and from official censuses. CLL prevalence and incidence were determined from a count of CLL cases (previously diagnosed and new cases) in the population who made at least one clinic visit for CLL during the period from 1 January 2009 to 31 December 2013. RESULTS: The recorded cumulative 5-year incidence of CLL during the study ranged from 1.46 per 100 000 persons (95% CI: 0.85-2.34) in Yekaterinburg, Russia, to 4.34 per 100 000 persons (95% CI: 2.48-7.04) in Luhansk, Ukraine. In 2013, the lowest prevalence of CLL was also recorded in Yekaterinburg: 7.11 per 100 000 persons (95% CI: 5.67-8.81). This was approximately 3.1 times lower than in Luhansk (21.92 per 100 000 population; 95% CI: 17.38-27.28). CONCLUSION: The results of this study show diverse CLL incidence and prevalence patterns in the adult population of the Russian Federation and Ukraine. Authors propose a more comprehensive study with large region involvement to provide a more precise description of the incidence and prevalence of CLL in Eastern European countries and to better understand disparities reported versus the USA and other Western countries.

BACKGROUND: Previous studies have suggested a greater benefit for various outcomes in men diagnosed with benign prostatic hyperplasia (BPH) who are treated with dutasteride than for men treated with finasteride. This study investigates whether the rates of BPH-related prostate surgery and acute urinary retention (AUR) differ between dutasteride and finasteride users in the Netherlands. METHODS: From the PHARMO Database Network, men aged ≥50 years with a dispensing of dutasteride or finasteride with or without concomitant alpha-blocker treatment between March 1, 2003 and December 31, 2011 were selected. The incidence of BPH-related prostate surgery and AUR was determined during dutasteride or finasteride treatment and stratified by type of initial BPH-treatment (5-ARI monotherapy or combination with alpha-blocker) and prescriber (general practitioner (GP) or urologist). Comparison of the incidence of BPH-related prostate surgery and AUR between the treatment groups was done by Cox proportional hazard regression. RESULTS: 11,822 dutasteride users and 5,781 finasteride users were identified. Most users started treatment in combination with an alpha-blocker. Overall, dutasteride users had a lower risk of BPH-related prostate surgery was lower among dutasteride users than finasteride users (HR: 0.75; 95 % CI: 0.56-0.99). This lower risk among dutasteride users was also seen when stratifying by monotherapy or combination therapy (HR: 0.73; 95 % CI: 0.54-0.98 for monotherapy and HR: 0.85; 95 % CI: 0.74-0.97 for combination therapy). However, the association was only present among men treated by urologists. For AUR the rates were low and no statistical significant difference was observed between dutasteride and finasteride users. CONCLUSIONS: The risk of undergoing BPH-related prostate surgery was lower among men using dutasteride compared to men using finasteride. The association was observed for monotherapy as well as combination therapy, however, only among men who received their prescription from a urologist.

OBJECTIVE: To investigate whether a fixed-dose combination (FDC) of 0.5 mg dutasteride and 0.4 mg tamsulosin is more effective than watchful waiting with protocol-defined initiation of tamsulosin therapy if symptoms did not improve (WW-All) in treatment-naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression. PATIENTS AND METHODS: This was a multicentre, randomised, open-label, parallel-group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8-19, prostate volume ≥30 mL and total serum PSA level of ≥1.5 ng/mL. Patients were randomised to FDC (369 patients) or WW-All (373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by the IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety. RESULTS: The change in IPSS at 24 months was significantly greater for FDC than WW-All (-5.4 vs -3.6 points, P < 0.001). With FDC, the risk of BPH progression was reduced by 43.1% (P < 0.001); 29% and 18% of men in the WW-All and FDC groups had clinical progression, respectively, comprising symptomatic progression in most patients. Improvements in QoL (BPH Impact Index and question 8 of the IPSS) were seen in both groups but were significantly greater with FDC (P < 0.001). The safety profile of FDC was consistent with established profiles of dutasteride and tamsulosin. CONCLUSION: FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, resulted in rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol.
