RESUMEN
OBJECTIVES: Asthma is a chronic airway disorder associated with variable airflow limitations, which are triggered by different stimuli. The reversibility of airflow limitations reflects patients' responses to the therapy with bronchodilators and improvements in airflow. This study aims to determine the treatment outcomes (improvements in forced expiratory volume in the first second (FEV1) and the number of asthma exacerbations) associated with the presence of airflow reversibility. METHODS: This retrospective cohort study included 154 adults (>18 years) who were diagnosed with asthma and had pulmonary function testing (PFT) at a tertiary care centre in KSA between January 1st, 2014 and May 31st, 2019. Smokers and patients with comorbidities or medications that could affect PFT were excluded from the analysis. Patients were classified as having a reversible airflow limitation when they exhibited a post-bronchodilator FEV1 increase of 12% and 200 mL. Exacerbations were defined as the need to use oral corticosteroids. Chi-square tests were used for comparative analyses. RESULTS: From our cohort, 42 patients exhibited reversibility. In contrast, 112 patients did not show any sign of reversibility. Asthmatics with baseline reversible airflow limitations experienced significant worsening of FEV1 during the follow-up period compared with those with no reversibility, showing a mean difference of 19.96 mL (p = 0.0206). There was no significant association between asthma reversibility and exacerbations (p = 0.23). CONCLUSION: In our study, during the follow-up of patients with asthma, we found that the reversibility of airflow was associated with significantly worse FEV1, although this did not have a significant effect on exacerbations. Therefore, we recommend regular spirometry follow-ups, particularly for patients with significant airway reversibility.
RESUMEN
BACKGROUND: Accumulating evidence demonstrates that white-coat hypertension (WCH) are associated with several risks and complications. In this study, we aimed to investigate the adverse effects of WCH compared with hypertensive and normotensive patients. METHODS: A retrospective cohort study was conducted over five years. Blood pressure (BP) data was collected from both clinic visits and 24-h ambulatory blood pressure monitoring (ABPM) reports. Epidemiological data and complications, cardiac and noncardiac, were also recorded. RESULTS: In total, 286 participants who were followed up for at least three years were included. The sample was divided into 99 normotensive patients (as a control group), 94 patients with clinically diagnosed hypertension (HTN), and 93 patients with WCH. Ischemic heart disease (IHD) was the most noted complication in the WCH group with a relative risk of 9.58 (1.23-74.16) (P = 0.008). Acute coronary syndrome (ACS) was significantly correlated with a relative risk of 2.06 (0.52-13.38). No significant correlation was noted with noncardiac complications. Both HTN and WCH groups showed a significant association with blood pressure variability (BPV). WCH was associated with an increased BPV in ambulatory daytime systolic measurements (P = 0.031) and a unique increase in diastolic measurement variability in office BP measurements (P = 0.020). CONCLUSION: WCH should be managed as HTN. WCH is associated with cardiac complications, particularly IHD, specifically in patients 55 years and older. WCH was significantly associated with a higher BPV in both ABPM and office-based measurements.
RESUMEN
Aim To identify the types of glaucoma and associated comorbidities among patients attending the ophthalmology clinic at King Abdulaziz Medical City (KAMC) in Jeddah. Methods A cross-sectional study that included all glaucoma patients at KAMC in Jeddah between June 1st, 2016 and November 30th, 2020. Data were collected through retrospective chart review from the electronic medical record system (BestCare) and utilized a structured data collection sheet. Results A total of 283 patients met the inclusion criteria. The most common type was primary open-angle glaucoma (POAG; 53%) followed by secondary glaucomas (SG; 26.5%) then childhood glaucoma and primary angle-closure glaucoma (CG, PACG; 7.4%). The majority of secondary glaucoma cases were due to neovascular glaucoma (NVG; 44.9%), followed by phacomorphic glaucoma (17.9%) and phacolytic glaucoma (10.3%). Hypertension (60.8%) and diabetes (58.3%) were the most prevalent systematic comorbidities, and cataract (49.1%) was the most prevalent ocular comorbidity. Conclusion POAG was the most common glaucoma type, followed by SG, CG, and PACG. Among secondary glaucoma types, neovascular glaucoma was found to be the most common subtype. Hypertension was the most prevalent comorbid condition.
RESUMEN
Objectives Alopecia areata (AA) is a common immune-mediated hair disorder that presents in different clinical patterns. This study aims to find the association between vitamin D and zinc levels with AA phenotypes, to determine the common comorbidities in AA patients, and to assess the influence of age, gender, and body mass index (BMI) on AA phenotypes. Methods This is a cross-sectional study conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Data were collected through retrospective chart review of the electronic medical record system (BestCare) and by utilizing a structured data collection sheet. Results A total of 177 patients were clinically diagnosed with AA with a mean age of 28.37 ± 12.68 years. The mean vitamin D level was 49.14 ± 29.09 nmol/L. Zinc levels were reported in only 22 patients, among which, only one patient had deficient levels. The mean zinc level was 9.8 ± 1.5 µmol/L. Patchy alopecia areata (60.45%) was the most common phenotype followed by universalis (9%) and totalis (7%). Hypothyroidism (11.8%) was the most prevalent comorbidity followed by atopic diseases (10.7%), then both diabetes and mood disorders (6.2%). Conclusion Deficient serum vitamin D levels were present in 62.7% of patients with AA. Nevertheless, no statistically significant relation was detected between vitamin D status and patterns of alopecia areata (P=0.108). A limited number of our sample had records of zinc levels with a mean serum of 9.8 ± 1.5 µmol/L and only one patient was found to be deficient.
RESUMEN
BACKGROUND: Psoriasis is a chronic, inflammatory, and immune-mediated dermatological disease of unknown etiology with predominant involvement of the skin, nails, and joints. This study aimed to assess comorbidities patterns in psoriasis patients. METHODS: This is a cross-sectional study conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Data were collected through a retrospective chart review of the electronic medical record system (Bestcare, Ezcaretech, Seoul, Korea) and by utilizing a structured data collection sheet. RESULTS: A total of 128 confirmed psoriasis cases were included with a mean age of 44.2 ± 17.3. The sample had 45.7% females and 54.3% males. Nearly half the patients (46.1%) had no comorbidities, followed by those who had at least one comorbidity (24.2%) and those who had two or more comorbidities (29.7%). Most patients were classified as plaque psoriasis (57.0%), followed by those who had psoriatic arthritis (13.3%). There was no statistical significance between gender, body mass index (BMI), and smoking with the number of comorbidities (P= 0.422, P=0.361, P=0.772); 41.2% of psoriatic arthritis patients and all erythrodermic arthritis patients had two or more comorbidities, which is statistically significant at p-value <0.018. CONCLUSION: This study demonstrated the prevalence of different comorbidities associated with psoriasis patients; 41.2% of psoriatic arthritis patients and all erythrodermic arthritis patients had two or more comorbidities, which was statistically significant. This necessitates closer monitoring of different comorbidities a psoriasis patient might present with. Especially those who are diagnosed with psoriatic arthritis and erythrodermic arthritis.
