Epidemiology and outcome of tuberculosis in immunocompromised patients.

Saudi J Kidney Dis Transpl 2017 Jul-Aug;28(4):806-817

The Saudi Center for Organ Transplantation, Riyadh, Saudi Arabia.

The United States Renal Data System showed 1.2% and 1.6% incidences of tuberculosis (TB) in patients on peritoneal dialysis and hemodialysis (HD), respectively. Kidney transplant (KTX) patients have higher rates. We studied the epidemiology and outcome of TB in patients with kidney dysfunction in a tertiary care hospital in the past decade. We examined data of patients with TB with and without kidney dysfunction from 2006 to 2015 through an electronic system. Statistical analysis was completed using Stata software, Chicago, IL, USA. We found 581 patients with active TB of whom 37 had renal dysfunction including chronic kidney disease, HD, and KTX. No difference was found in the prevalence, age, or gender predilection. The age ranged from 1 to 95 with a mean (standard deviation) of 38.6 (21.1) years. The incidence of TB is 3 per 100,000. The number of patients per year with active TB ranges from 52 to 128 and 3 to 4 in the general population and kidney dysfunction group, respectively. Sixty-five percent of patients with kidney dysfunction had pulmonary TB, 5% had pleurisy, and 30% had extrapulmonary TB. Eighty-four percent of patients with kidney dysfunction completed the course of treatment with 16% treatment failure and 0.4% developed multidrug-resistant TB; 8% were lost to follow-up and 8% died during the treatment period. This study showed no gender predilection for TB in the general population and immunocompromised. Duration of symptoms before diagnosis of TB was shorter in kidney dysfunction patients in comparison to the general population. TB cultures were the most positive tests whereas bronchoalveolar lavage and skin test were the least positive for detecting TB in the kidney dysfunction group. Improvement in registries and screening is required to enhance the capturing rate and detection among this group, as well as providing accurate data to health authorities and the public about the magnitude, future trends, treatments, and outcomes regarding TB in kidney dysfunction.

Clinical features of Sarcoidosis in Oman: A report from the Middle East region.

Sarcoidosis Vasc Diffuse Lung Dis 2016 Oct 7;33(3):201-208. Epub 2016 Oct 7.

Sultan Qaboos University.

Background: Though clinical features of sarcoidosis follow a similar pattern, some heterogeneity is seen in different ethnic and racial groups.

Objectives: To describe for the first time the clinical characteristics of sarcoidosis patients in the Sultanate of Oman.

Methods: The data on all cases of sarcoidosis followed up in the two tertiary hospitals in Oman were retrieved retrospectively.

Results: Of the 92 patients, for representing the ethnic data only Omani patients (n=83) were included. The mean age was 52.90±12.35 years. Majority were females (72.3%, n=60). Cough (n=44, 53.0%), dyspnea (n=39, 47%), arthralgia (n=26, 31.3%) and fatigue (30.1%) were the major symptoms. Arthralgia was reported by 41.7% of the females and 4.3% of the males (p= 0.001). Uveitis was present in 16 (19.3%), erythema nodosum in 8 (9.6%) and hypercalcemia in 13 (15.7%). The radiological stage at presentation was stage 0, 18.7%; I, 28%; II, 17.3%; III, 24% and IV, 12%. Majority (61.4%) of the patients had tissue diagnosis; intra-thoracic site 70.6%. Pulmonary function showed abnormal diffusion in 75%. Sixty eight received treatment, 81.9% took prednisolone. Based on radiograph good outcome (Resolving) was noted in 20.9%, intermediate (Stable) in 73.1% and poor (Progressive) in 6%. Lung function wise, resolving, stable and progressive disease was seen in 31.4%, 40.0% and 28.6% respectively.

Conclusion: The clinical picture of the patients with sarcoidosis from Oman was similar to that reported from the rest of the world. Region wise, our patients were older and arthralgia and hypercalcemia were more common. The management of sarcoidosis needs a more organized approach in the country with clear guidelines on monitoring and treatment.

The Burden of Asthma in Oman.

Sultan Qaboos Univ Med J 2015 May 28;15(2):e184-90. Epub 2015 May 28.

Department of Medicine, Respiratory Unit and, Royal Hospital, Muscat, Oman.

Asthma is a common lung disease worldwide, although its prevalence varies from country to country. Oman is ranked in the intermediate range based on results from the International Study of Asthma and Allergies in Childhood. A 2009 study revealed that the majority of asthmatic patients in Oman reported both daytime and nocturnal symptoms, while 30% of adults and 52% of children reported absences from work or school due to their symptoms. Despite these findings, there is little data available on the economic burden of asthma in Oman. The only accessible information is from a 2013 study which concluded that Oman's highest asthma-related costs were attributable to inpatient (55%) and emergency room (25%) visits, while asthma medications contributed to less than 1% of the financial toll. These results indicate a low level of asthma control in Oman, placing a large economic burden on healthcare providers. Therefore, educating asthmatic patients and their families should be prioritised in order to improve the management and related costs of this disease within Oman.
