Antibiotic Resistance among Patients with Urinary Tract Infections in Kandahar, Afghanistan.

Background: Antimicrobial resistance is a global public health threat. Highest burden of resistance is reported from low- and middle-income countries. Objectives: To investigate and report the current scenario of increased antibiotic resistance of uropathogens among symptomatic urinary tract infection patients in Kandahar, Afghanistan. Methods: From January 2018 to December 2021, this retrospective study was carried out at two main hospitals in Kandahar City, Afghanistan. Here, culture and sensitivity profiles of uropathogens were studied among symptomatic Bacteriuria in the presence of genitourinary symptoms (i.e., dysuria, suprapubic pain or tenderness, frequency, or urgency) (UTI) patients. Results: Among urine samples of 1589 patients, 1047 (65.9%) were culture positive and included in this study. Most of these patients (626/1047 [59.8%]) were females, with majority (818 [78.1%]) having age between 19 and 39 years. Gram-negative bacteria were the most prevalent (840/1047 [80.2%]), with E. coli (653/1047 [62.4%]) as the most common isolated uropathogen. Overall gram-negative bacteria had higher resistance against commonly used antibiotics of cotrimoxazole (62.8%), ciprofloxacin (56.0%), levofloxacin (47.5%), cefixime (44.5%), fosfomycin (41.5%), and even ceftriaxone (48.3%). Conclusions: Kandahar province has higher resistance rates against commonly used empirical antibiotics like norfloxacin, ciprofloxacin, levofloxacin, and cefixime. Nitrofurantoin should be used as the first-line antibiotic in treating UTI patients. Public health authorities should make strict regulations and policies to reduce irrational use, inappropriate prescription, and over-the-counter availability of antibiotics in Kandahar.

Treatment outcome of tuberculosis treatment regimens in Kandahar, Afghanistan.

BACKGROUND: Tuberculosis (TB) is a chronic disease that mostly affects low-income countries. TB is transmitted through droplet aerosolization from a person with active pulmonary TB. Afghanistan is one of the 22 high TB burden countries where 39,445 people develop this disease and 7840 people die each year. Treatment outcome is one of the best measurements that explain how the current regimen works. MATERIAL AND METHODS: This was a retrospective cohort study, conducted in Kandahar Province, to find out the treatment outcome of anti-TB drugs regimens in TB patients. Data of pulmonary and extra-pulmonary TB patients, who fulfilled the eligible criteria of the study and were treated from 2005 to 2015, was retrieved from their medical record forms. RESULTS: Among 1000 TB patients, 599 (59.9%) were females and 401 (40.1%) males; most of the patients (678/1000 [67.8%]) were from Kandahar city while 322/1000 (32.2%) were from the other districts of Kandahar. Mean age of the patients were 36.1 years with SD of 19.3 years. Main signs and symptoms of fever, cough, and weight loss were present in 949/1000 (94.9%), 880/1000 (88%), and 544/1000 (54.4%) of the patients, respectively. On first visit 459/1000 (45.9%) patients were sputum AFB (acid fast bacilli) positive. Majority (247/459 [53.8%]) of these patients were AFB 2+. After 2 months of intensive anti-TB treatment, 9/459 (1.9%) patients were still AFB positive (1+). Treatment outcome of these 1000 patients showed that 479 (47.9%) completed the treatment, 298 (29.8%) were cured, 35 (3.5%) failed the anti-TB treatment, while 5 (0.5%) patients died. CONCLUSION: This clearly shows that TB is still one of the major threats to the people of Kandahar Province. There are cases of TB who do not respond to the first line regimens of anti-TB drugs advised by WHO and Afghan Ministry of Public Health (MoPH).

Determinants of treatment failure among tuberculosis patients in Kandahar City, Afghanistan: A 5-year retrospective cohort study.

Background: Tuberculosis (TB) is a preventable and treatable chronic disease. Afghanistan is among the high-TB-burden countries. The aim of this study is to find the determinants of treatment failure among TB patients in Kandahar City, Afghanistan. Methods: This was a retrospective cohort study conducted in Kandahar City during a period of 5 years (August 2014-July 2019). For data analysis; descriptive statistics, Chi-square test, and logistic regression were used. Results: Among 1416 TB patients, 894/1416 (63.1%) had pulmonary TB (PTB), whereas 522/1416 (36.9%) had extrapulmonary TB (EPTB). Mean age in these patients was 34.7 years while most of them were females in PTB (530/894 [59.3%]) and EPTB (340/522 [65.1%]) patients. Sputum smear was positive in 618/860 (71.9%) and 16/404 (4%) of PTB and EPTB patients, respectively. TB treatment failure was more in PTB (56/894 [6.3%]) than EPTB (4/522 [0.8%]). Chi-square test of TB cases showed that statistically significant determinants that may cause the treatment failure were re-treatment cases (crude odds ratio [COR] 7.7, P < 0.001), absence of fever (COR 5.2, P < 0.001), absence of cough (COR 1.7, P = 0.004), living in rural areas (COR 1.4, P = 0.035), and no weight loss (COR 1.3, P = 0.033). Binary logistic regression of the statistically significant variables revealed only absence of fever (adjusted odds ratio 6.0, P < 0.001) as the risk factor for treatment failure in TB patients. Conclusion: TB is still a major threat for Kandahar City. Low treatment success rate and increased number of defaulted cases are the major threats.
