We present the case of a 17-year-old boy who was admitted to the medical ward of MBGH, RNT Medical College, Udaipur with complaints of fever with chills and rigor for 6 days. Patient noticed blackening of his toes and lower limbs on the third day of fever which was associated with pain and numbness. There was no history of trauma, any drug ingestion, alcohol use, and smoking. Examination revealed pulse 110 beats/min, regular, bounding, with all peripheral pulses felt normally, blood pressure - 100/40 mmHg in right brachial artery, temperature of 101.4°F, respiratory rate - 22 breaths/min. On examination, patient was found to have severe pallor, mild icterus, and blackening of third, fourth, and fifth toe of right foot and fifth toe of left foot with circumferentially patchy area of blackening of bilateral lower legs up to mid-shin [Figures and ]. Overlying skin was dry and wrinkled. Per abdominal examination revealed firm splenomegaly 2 cm below costal margin. Neurological examination revealed decreased sensations over hyper-pigmented area. Cardiovascular system examination revealed a soft functional ejection systolic murmur present at pulmonary area heard all over the precordium. Respiratory system examination was unremarkable. Provisional diagnosis of septicemia with SPG was kept and patient was investigated.\nBlood investigation revealed hemoglobin (Hb) 1.1 g%, total leucocytes count (TLC) 1000 cells/mm3, with 55% polymorphs and 40% lymphocytes, platelets 10,000/mm3 with normocytic normochromic picture on peripheral blood film (PBF) with no immature cells and no parasite was seen. Renal and liver functions tests were normal. Malarial parasite quantitative buffy coat was negative but rapid diagnostic kit for P. falciparum was positive. Anti-nuclear antibody, rheumatoid factor, C-reactive protein, human immunodeficiency virus, hepatitis B surface antigen, anti-hepatitis C virus were negative. Prothrombin time-international normalized ratio (PT-INR) was 18 and 1.41 (control 13). Bleeding time, clotting time were normal. Chest X-ray was normal. Ultrasonography of abdomen revealed gall bladder sludge and mild splenomegaly. Blood culture did not show growth of any pathogenic organism. Color Doppler of both lower limbs showed normal caliber, flow and Doppler indices of bilateral femoral, popliteal, anterior and posterior tibial arteries [].\nDiagnosis of complicated P. falciparum malaria with disseminated intravascular coagulation (DIC) with SPG was kept and patient was treated with injection quinine 600 mg intravenous (IV) 12 hourly slow infusion in 10% Glucose Distilled Water, tablet doxycycline 100 mg twice daily, injection ceftriaxone 1 g IV 12 hourly and with supportive three units of packed cell volume and six units of platelets. After a consultation from cardiothoracic vascular surgeon patient was started on low dose heparin infusion for SPG but patient developed epistaxis soon after starting the infusion, so infusion was stopped and managed conservatively. Patient had an uneventful recovery and discharged from hospital after 10 days. On discharge patient's vitals were normal, Hb - 6 g%, PBF showed normocytic normochromic anemia with occasional macrocytes, TLC - 11,000 cells/mm3, platelets - 1.8 lac/mm3, PT-INR - 15 and 1.19.
A 50-year-old uneducated male of low socioeconomic status was scheduled for amputation of toes. To start with, he had complaint of fever associated with chills and rigors for 3 weeks. He consulted a local practitioner who prescribed some tablets about which patient could not give the details. He noticed blackening of toes of both the feet, which was slow and progressive over 1 week. As he was not responding to the treatment, he was rushed to our medical college. There was no history of trauma, significant drug ingestion particularly ergot, alcohol consumption or smoking. On physical examination, he was febrile, dehydrated, and had pallor; there was no icterus, cyanosis, edema, or significant lymphadenopathy. A pulse rate of 120/min, respiratory rate of 24/min, and blood pressure of 90/70 mmHg was recorded. All peripheral pulses were palpable. On systemic examination, mild hepatosplenomegaly was present and rest of the systemic examination was normal. On local examination, there was blackish discoloration of all toes, extending up to malleoli [Figures and ]. Intavenous line was secured. Ringer lactate was started and investigations were sent for. Reports were as follows [].\nPeripheral blood smear showed ring forms of P. falciparum with occasional gametocytes. Three consecutive blood cultures for bacteria were negative. Color Doppler study of the lower limbs revealed normal flow in both the femorals and the popliteal, with slightly reduced flow in tibial and dorsalis pedis artery with hypoechogenic shadow in its lumen.\nThe patient was given i.v. quinine, loading dose of 20 mg/kg followed by a maintenance dose of 10 mg/kg thrice a day for 2 days. Then, the patient was shifted to oral quinine (dose 10 mg/kg) thrice a day and oral paracetamol 500 mg thrice a day for 5 days. Two units of packed cell transfusion were also given. Fever subsided within 5 days of treatment. His peripheral smear for malarial parasite became negative after 7 days of quinine course. Line of demarcation did not progress any further. For management of gangrene, amputation was planned. All repeated blood investigations were within normal limits except prothrombin time 16.5 s, fibrinogen level 2.9 g/L (normal value 1.5-4 g/L), and D-dimer 1.7. The surgery was done under total i.v. anesthesia.
