Tuberculosis and Diabetes in India: Stakeholder Perspectives on Health System Challenges and Opportunities for Integrated Care.

BACKGROUND: India has a dual burden of tuberculosis (TB) and diabetes mellitus (DM). Integrated care for TB/DM is still in the early phase in the country and can be considerably enhanced by understanding and addressing the challenges identified from stakeholders' perspectives. This study explored the challenges and opportunities at individual, health system and policy level for integrated care of TB/DM comorbidities in India. METHODS: We used an outlier case study approach and conducted stakeholder interviews and focus group discussions with relevant program personnel including field staff and program managers of TB and DM control programs as well as officials of partners in Indian states, Kerala and Bihar. RESULTS: The integrated management requires strengthening the laboratory diagnosis and drug management components of the two individual programs for TB and DM. Focused training and sensitization of healthcare workers in public and private sector across all levels is essential. A district level management unit that coordinates the two vertical programs with a horizontal integration at the primary care level is the way forward. Substantial improvement in data infrastructure is essential to improve decision-making process. CONCLUSION: Bi-directional screening and management of TB/DM comorbidities in India requires substantial investment in human resources, infrastructure, drug availability, and data infrastructure.

Adjuvant antibiotic loaded bio composite in the management of diabetic foot osteomyelitis - A multicentre study.

BACKGROUND: Diabetic foot ulcers are associated with a high morbidity and are common cause of non-traumatic lower limb amputations. The effect of debridement and the use of an adjuvant local antibiotic carrier in the treatment of diabetic foot ulcers with osteomyelitis was evaluated. METHODS: A retrospective review of patients with diabetic foot ulceration and osteomyelitis treated by debridement with adjuvant local antibiotic was performed. Seventy patients with Texas Grade 3B & 3D lesions were included, with a mean age of 68 years. Cerament G, an antibiotic-loaded absorbable calcium sulphate/hydroxyapatite bio-composite was used along with intraoperative multiple bone sampling and culture-specific systemic antibiotics. RESULTS: Patients were followed up until infection eradication or ulcer healing. Mean follow up was 10 months (4-28months). Nine patients had Charcot foot deformity, 14 had peripheral vascular disease. 62% of patients had forefoot, 5% midfoot and 33% hind foot involvement. Fifty-three patients (87%) had polymicrobial infection. Staphylococcus aureus was the most common microorganism isolated. Infection was eradicated in 63 patients (90%) with mean time to ulcer healing of 12 weeks. Seven patients were not cured and required further treatment. Five patients had below knee amputation. CONCLUSIONS: Adjuvant, local antibiotic therapy with an absorbable bio-composite can help achieve up to 90% cure rates in diabetic foot ulceration with osteomyelitis. Cerament G can act as effective void filler allowing dead space management after excision and preventing reinfection and the need for multiple surgical procedures. LEVEL OF EVIDENCE: Level IV- case series.

Single stage treatment of diabetic calcaneal osteomyelitis with an absorbable gentamicin-loaded calcium sulphate/hydroxyapatite biocomposite: The Silo technique.

BACKGROUND: Chronic osteomyelitis necessities appropriate infected bone and soft tissue excision. The authors describe the Silo surgical technique for the treatment of calcaneal osteomyelitis using a new antibiotic-loaded absorbable calcium sulphate/hydroxyapatite biocomposite. METHODS: The Silo method involves debridement of the dead bone and local delivery of antibiotic in drilled tunnels using the biocomposite. It is combined with multiple sampling and culture-specific systemic antibiotic treatment guided by a multidisciplinary team. Twelve consecutive diabetic patients with heel ulcers and calcaneal osteomyelitis were treated with the above method. All had comorbidities (Cierny-Mader (C-M) Class B hosts). The mean age was 68 years (range 50-85). A retrospective review of radiographs and electronic medical records was conducted. RESULTS: Patients were followed up until clinical cure of the ulcer for a mean of 16 weeks (range 12-18). Infection was eradicated in all 12 patients with a single stage procedure following a bone preserving technique. One patient required a subsequent flap operation and six vacuum-assisted closure (V.A.C.). There was also one case of prolonged wound leakage and no calcaneal fractures. CONCLUSIONS: The Silo technique is an effective method of local delivery of antibiotics and can be effectively implemented into the single-stage treatment of calcaneal osteomyelitis offering increased bone preservation and local delivery of antibiotic, decreasing the need for a major amputation. LEVEL OF EVIDENCE: Level IV- case series.
