ABSTRACT
Backgrounds People living with human immunodeficiency virus (HIV) are at a greater risk of chronic kidney disease (CKD) compared to people not having HIV. Evaluating the prevalence of CKD in people living with HIV in Dammam, Saudi Arabia was the main objective of this study. Methods This cross-sectional study included adult HIV patients who were followed at Dammam Medical Complex. The patients' demographic data, comorbid conditions, and HIV history were reviewed from their electronic medical records. Results A total of 729 patients were counted. The glomerular filtration rate (GFR) of 235 patients could not be estimated. The data for the remaining 494 patients were analyzed. The cohort consisted of 406 male patients (82.19%) and 88 female patients (17.81%). The mean ± standard deviation for the patients' age and HIV duration were 39.08±10.93 years and 4.37±3.15 years, respectively. Ten patients (2.02%) had a GFR of <60 mL/min/1.73 m2. Among 136 patients who had an estimated GFR of ≥60 mL/min/1.73 m2 and were tested by a urine examination, 27 patients (19.85%) had albuminuria. Combining the two figures resulted in an estimated prevalence of CKD in HIV patients of 21.47%. Only one patient (0.02%) was receiving dialysis. Conclusions The prevalence of CKD in people living with HIV in Dammam, Saudi Arabia was higher than the general population. The findings highlight the elevated risk of CKD among people living with HIV and emphasize the importance of regular monitoring and early detection of kidney dysfunction in this population.
ABSTRACT
Background Hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections are more prevalent in hemodialysis patients compared to the general population. The objective of this study was to evaluate the prevalence of HBV, HCV, and HIV infections in hemodialysis patients dialyzing regularly at Kano Kidney Center (KKC) in the Eastern Health Cluster of Saudi Arabia in 2022. Methods This retrospective study included all hemodialysis patients who were dialyzed regularly at KKC during 2022. Their electronic medical records were reviewed for the results of HBV, HCV, and HIV along with the patient's demographics, comorbid conditions, and dialysis history. The study was approved and monitored by the Institutional Review Board of Dammam Medical Complex. Results A total of 239 regular hemodialysis patients were included, consisting of 142 males and 97 females (59.41% and 40.59%, respectively), with a mean age of 52.71±15.83 years. Most of the patients were Saudis (156 patients, 65.27%) with the non-Saudi patients being composed mostly of Arabian patients. Nine patients (3.77%) tested positive for hepatitis B surface antigen (HBsAg), the serologic hallmark of HBV infection. Two patients (0.84%) had resolved HBV infections as evidenced by positive hepatitis B core antibody (anti-HBc) and hepatitis B surface antibody (anti-HBs). However, the majority (226 patients, 94.56%) were never tested for anti-HBc. Anti-HBs, which can imply long-term immunity against HBV from prior immunizations or infections, were positive in 165 patients (69.04%). A protective anti-HBs level of ≥ 10 IU/L was detected in 158 patients (66.11%) including 104 patients (43.51%) having ≥ 100 IU/L. Eighteen patients (7.53%) had reactive HCV antibodies. Four patients (1.67%) had chronic HCV infection as they had detectable HCV RNA. The remaining 14 patients (5.86%) cleared HCV either spontaneously (seven patients, 2.93%) or by medications (seven patients, 2.93%). HIV screening tests were negative in all 239 patients (100%). HBsAg-positive patients did not have any statistically significant differences from HBsAg-negative patients. On the other hand, the patients who were positive for HCV antibodies were older than the patients who were negative for HCV antibodies (60.66 vs 52.05 years on average, p-value <0.05). They also contained a statistically larger proportion of non-Saudi patients than the patients with no evidence of prior infections (61.11% vs 32.13%, p-value <0.05). Conclusions The study found that the prevalence of HBV and HCV infections among hemodialysis patients in KKC at 3.77% and 1.67%, respectively, is higher than that reported in the general population in Saudi Arabia, with non-Saudis having a higher prevalence rate of HCV infection than Saudis. However, the current prevalence rate is lower compared to the previous studies that were conducted in Saudi Arabia in the first decade of the 21st century, and there were no cases of HIV infections. Nevertheless, a significant proportion of patients had unprotective or negative anti-HBs antibody titers, indicating the need for strict vaccination protocols and monitoring of antibody titers to ensure optimal protection.
ABSTRACT
Background Malaria transmission was stopped on most of the vast area of the Kingdom of Saudi Arabia. However, the pandemic of coronavirus disease (COVID-19) has negatively affected the efforts to control malaria. For instance, COVID-19 was reported to induce a relapse of malaria that is caused by Plasmodium vivax. Furthermore, physicians' attention toward COVID-19 can only result in neglect and delayed diagnosis of complicated malaria cases. These factors, among others, might have contributed to an increase of malaria cases in Dammam, Saudi Arabia. Thus, this study was conducted to examine the effects of COVID-19 on malarial cases. Methods The medical records of all patients who were treated at Dammam Medical Complex for malaria between July 1, 2018, and June 30, 2022, were reviewed. Malaria cases were compared between the pre-COVID-19 period (between July 1, 2018, and June 30, 2020) and the COVID-19 period (between July 1, 2020, and June 30, 2022). Results A total of 92 malaria cases occurred in the total study period. There were 60 cases of malaria in the COVID-19 period as opposed to only 32 cases in the pre-COVID-19 period. All the cases were imported from the endemic Saudi southern areas or from outside the country. Eighty-two patients (89.1%) were males. Most of them were Sundaneses (39 patients, 42.4%), Saudis (21 patients, 22.8%), and tribal peoples (14 patients, 15.2%). Fifty-four patients (58.7%) were infected with Plasmodium falciparum. Seventeen patients (18.5%) were infected with Plasmodium vivax. Another 17 patients (18.5%) had a mixed infection with both Plasmodium falciparum and Plasmodium vivax. A trend toward more infected stateless tribal patients was observed in the COVID-19 period compared to the pre-COVID-19 period (21.7% vs 3.1%). A similar trend was noticed for mixed malarial infections with both Plasmodium falciparum and Plasmodium vivax (29.8% vs 0%) with a P value of less than 0.01. Conclusion Malaria cases were almost doubled during the COVID-19 pandemic as compared to the pre-pandemic era signifying the negative effects of the pandemic on malaria epidemiology. The cases increased for a variety of causes that include alternation of health-seeking behaviors, changes in healthcare structures and regulations, and the interruption of malaria preventive services. Future research is needed to study the long-term effects of the changes imposed by the COVID-19 pandemic and to mitigate the effects of any future pandemic on malaria control. As two patients from our cohort were diagnosed with malaria based on blood smears, although they had negative rapid detection tests (RDTs), we recommend testing all the patients who are suspected to have malaria with both RDTs and peripheral blood smears.
ABSTRACT
INTRODUCTION: Glomus tumors are rare neoplasms that aris-e from neuromyoarterial canal or glomus body. They are mainly found in the peripheral soft tissue, extremities and rarely developed inside the gastrointestinal tract. In the gastrointestinal tract, the stomach is the most common site for the development of glomus tumors, and most often found in the antrum. Usually, the symptoms of gastric glomus tumors are non specific i.e (abdominal pain, GI bleeding and/or perforation) and possibly discovered incidentally during upper GI endoscopy. CASE PRESENTATION: This is a-56-year-old-male, presented to the emergency department with upper GI bleeding i.e (melena), and signs of shock (HR: 110; BP:80/60), Blood tests showed Hemoglobin level: 5 g/dl. Resuscitation was started with IV fluid and transfusion of 4 units of PRBCs. After resuscitation, He gave a 10 days history of passing black tarry stool, palpitation, headache, dizziness, easily fatigability, malaise, and colicky epigastric abdominal pain. His abdomen was soft, lax with no tenderness, there was fullness at the left upper quadrant. Upper GI endoscopy was performed that showed a large gastric ulcer with adherent clots, necrotic base and oozing at the proximal part of the greater curvature, after that the bleeding was managed with a heater probe and epinephrine injections. The histopathological examination of the biopsy revealed a spindle and epithelioid tumor with the top differential diagnosis being GIST, however other submucosal lesions cannot be excluded. After that, He underwent exploratory laparotomy and wedge resection of the tumor. The final histopathology showed a malignant glomus tumor. CLINICAL DISCUSSION: Due to overlapping clinical and radiological features between glomus, GIST and other submucosal lesions, the histopathological examination is considered to be the gold standard for the diagnosis. Surgical resection with negative margin is the treatment of choice for gastric glomus tumors. CONCLUSION: Although gastric glomus tumor is a rare entity and accounts for 1% of all gastric mesenchymal tumors, it should be considered in the differential diagnosis, since preoperative biopsy is difficult and overlapping features with other submucosal lesions. Surgical treatment is the preferred option for gastric glomus tumor and long-term follow-up is required due to high metastatic and recurrence rate in the malignant type.
